DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0142] FIGS. 1 to 3 show a schematic structure of the device for cleaning and disinfecting objects, in particular for cleaning and disinfecting the interior of objects such as medical equipment, shoes, helmets, gloves, sports equipment, T-shirts, shirts, suits (garments) and bags. The device comprises a box RB having a chamber 2/cleaning chamber formed herein in a housing 1, wherein the housing 1 is insertable into and withdrawable from a cabinet body 1a of the box RB enclosing the housing 1 via a rail system (not shown). The cabinet body 1a is open in the direction of the housing 1 (via a vertically extending undesignated opening), so that the housing 1 can be pushed into it. Otherwise, the cabinet body is closed off at the bottom, top, sides and rear. The housing 1 with the chamber 2 (cleaning chamber), which can be pushed into the cabinet body 1a, is preferably frame-like in this case. The housing 1 has a base B and a lid D, wherein the base B and the lid D are connected to one another via two end-side vertical and mutually parallel side parts S1, S2. The side part S1 is arranged in the direction towards the cabinet body 1a and the side part S2 is arranged opposite thereto. The side part S2 closes the cabinet body 1a in the inserted state. (See FIG. 1)

[0143] The device has in the lower region an air supply 3 in the form of a channel, wherein the housing 1 has at its front an opening in the form of an air inlet 3.1 for the air supply 3 leading into the chamber 2, wherein a fan 3.2 is arranged at the housing-side end of the air supply 3, which forms the air inlet 3.1. The fan 3.2 is designed in such a way that fresh air is drawn in from the environment and can be conveyed through the air supply 3 into the chamber 2.

[0144] The air supply 3 is preferably of tubular design and has an angle at its chamber-side end 3.3, preferably of 90°. The angle acts as a guide for the air, whereby a central outflow of the aspirated air in the chamber 2 can be achieved.

[0145] Two hollow-shaped main bodies 4 are provided, both of which are connected to the chamber-side end of the air supply and extend upwards into the chamber 2.

[0146] Each main body 4 has an air guide by means of which the air flow guided through the end on the chamber side can be divided into a first and second air flow. For each air flow, each main body has a UV radiation source arranged at an outlet opening of the air flow.

[0147] Depending on the design of the main body, the outlet openings are arranged radially or, in the example shown, axially with respect to the flow of air.

[0148] The wavelength of the ultraviolet radiation is preferably between 100 and 300 nm. The ultraviolet radiation is so short-wave and energy-rich that it is absorbed by molecular oxygen (O.sub.2). In this process, the molecular oxygen (O.sub.2) is split into two free oxygen radicals (2 O°), each of which reacts further with another molecule of oxygen (O.sub.2) to form ozone (O.sub.3).

[0149] The ozone thus formed at the UV lamp 5 disinfects the objects against germs, fungi and bacteria.

[0150] Furthermore, the chamber 2 (main chamber or cleaning chamber) comprises an exhaust device 6 in the ceiling area of the chamber 2. The suction device 6 is preferably arranged in the upper region of the device, here at the top in the side part S2, and comprises, for example, an air outlet 6.1 leading outwards through the housing 1 at its front, in which a second fan 6.2 is mounted. The fan 6.2 is configured to draw air out of the chamber 2, thereby creating a negative pressure. An alternating pressure is achieved in the chamber 2, and the suction device 6 may be configured such that a vacuum can also be generated in the chamber 2. The vacuum-air alternating system removes dead, living and eliminated organisms from the objects. The suction device 6 with the air outlet 6.1 may be preceded by a replaceable filter, which is not shown, so that the polluted air can be cleaned and the ozone removed before it exits the chamber.

[0151] For more effective cleaning, the air in the region of the air supply 3 is heated or cooled or alternately heated and cooled. For this method step, a heating device 3.4 is arranged in the region of the air supply 3, which is preferably wound around the air supply 3 in the form of a heating coil. Alternatively, a fan heater can also be used as a combination of heating device 3.4 and fan 3.2. The air flowing through the air supply 3 is heated in the region of the heating device 3.4. Alternatively or additionally, a cooling element 6.1 can be provided in the area of the air supply 3.

[0152] It is also possible to heat or cool a heating or cooling element in the cleaning chamber 2 and accordingly the interior of the chamber.

[0153] In an advantageous design, according to FIGS. 1 and 2, a water tank 7 with a heating element 7.1 arranged therein is provided in the base region of the device. The water is heated in such a way that water vapor is produced, wherein the water vapor is supplied to the air supply 3 via a conduit 7.2.

[0154] Mixing of heated air and the generated water vapor takes place, wherein the mixture is fed to chamber 2 via the chamber-side end 3.3.

[0155] The garment to be cleaned is smoothed by the moisture-enriched air, which eliminates the need for subsequent ironing. The water tank 7 is advantageously designed to be filled via a side opening or to be completely removable.

[0156] It is also possible for the base B to be double walled and for air to be directed into the chamber 2 from the air inlet 3.3 via the air supply 3 through the base-side cavity formed as a result. Similarly, water vapor may also flow through the base-side cavity into the chamber 2 via the air inlet 3 or another inlet (not shown).

[0157] The fan 3.2, the heating device 3.4, the water tank 7 and the heating element 7.1 are then also arranged in the base-side cavity.

[0158] In addition, a fragrance capsule 8 may be insertable into the air supply 3 to produce a fresh scent of the objects. The released fragrances may be added with the air drawn in by the air supply 3 and directed into the chamber 2. Preferably, the fragrance intensity is adjustable via a manual controller 8.1 or via the control unit 9 with a front display of the device.

[0159] The device also offers the possibility to gently dry damp objects in a short time.

[0160] With the device according to the invention, an environmentally friendly cleaning and disinfection of the objects is possible without the addition of chemical cleaning agents. Viruses, bacteria, germs and fungi and their spores according to Table 1 and other pathogens are effectively eliminated.

[0161] In FIG. 1, the device is shown in the closed state. The insert in the form of the housing 1 is inserted into the cabinet body 1a of the box RB, with the side part S2 closing off the cabinet body 1a. A seal may be provided between the side part 1 and the cabinet body 1a.

[0162] The side part S2 contains the display 9, the air inlet 3.1 and the air outlet 6.1. Alternatively, the air inlet 3.1 and the air outlet may also be located in the rear side part S1 (not shown), in which case the cabinet body 1a should be open at its rear side, which is not designated, at least in these areas.

[0163] The device is operated by means of the display 9 or also via an app.

[0164] It is possible to arrange one or more main bodies in the chamber 2, so that one or more objects can be disinfected and refreshed simultaneously.

[0165] According to FIGS. 2 and 3, the housing 1 of the box RB has a chamber 2 (main chamber or cleaning chamber) with an air supply 3 with an air inlet 3.1 arranged in the front and an alternatively designed main body 4. The main body 4, which is of hollow construction, is directly connected at its underside to the air supply 3 and extends upwards in a branching configuration and is in the form of a first adapter 4.5 and a second adapter 4.6, which extend upwards into the chamber 2. The first and second adapters 4.5, 4.6 of the main body 4 are of course also hollow and have an air guide 4.5.1, 4.6.1, by means of which the air flow guided through the chamber-side end 3.3 to each adapter 4.5, 4.6 can be divided and thus leads in a first air flow into the first adapter 4.5 and in a second air flow into the second adapter 4.6.

[0166] The first adapter 4.5 and the second adapter 4.6 each have two branches. In the area of each branch at least one outlet opening 4.5.2, 4.6.2 is provided, according to FIG. 2 a total of four outlet openings (two for each adapter 4.5, 4.6), in the area of each of which a UV radiation source 5 is arranged. The outlet openings can be arranged radially or axially with respect to the individual air flow. In the present example according to FIG. 5, the first adapter is of Y-shaped (Y) design and has a first and second UV radiation source 5 at its chamber-side end. Such an adapter is particularly suitable for positioning objects forming a cavity in the form of shoes, gloves, breathing masks, helmets and the like, as these are placed or plugged onto a single UV radiation source 5 or two UV radiation sources 5 in a spanning manner.

[0167] The second adapter 4.6 differs in its shape from the first adapter 4.5 in such a way that the two air flows or air channels are brought together again, or are connected to each other. The shape of the second adapter 4.6 corresponds to a “koppa” (o Greek alphabet). The UV radiation sources 5 are arranged in the region of the two divided air streams. With such a design of an adapter 4.6 textile objects can be hung up without a further hanger.

[0168] In the chamber 2 (main chamber or cleaning chamber), a main body with preferably two adapters is thus arranged here, wherein two adapters of the first adapter type 4.5, two adapters of the second adapter type 4.6 or one adapter each of the first type 4.5 and the second type 4.6 are used. Preferably, in the first and second adapters 4.5, 4.6 the wirings for the connection of the UV radiation sources 5 are provided.

[0169] The adapters 4.5, 4.6 may have symmetrically and/or asymmetrically distributed holes and/or passages throughout for distributing the air or water vapor.

[0170] Above the area of the air supply 3.3 arranged on the chamber side in the base B, a vertically extending area of an air channel 4A is provided. Adjacent to its upper end are the first and second adapters 4.5 and 4.6 of the main body 4, which are of channel-like design and through which the air flow is further divided.

[0171] It is possible that the adapters 4.5 and 4.6 are formed integrally with the air channel 4A and are removably and interchangeably attached to the base, or that the adapters 4.5 and 4.6 are formed separately and are removably attached to the upper end of the air channel 4A.

[0172] In any case, for example, only one or two or more first adapters 4.5 or one or two or more second adapters or a different number and combination of adapters may be used, depending on the object to be cleaned.

[0173] According to FIGS. 5 and 6, the water tank 7 of the box RB with a heating element not shown arranged therein is arranged in the region of the transition between the chamber-side end 3.3 of the air supply and the first and second adapters 4.5, 4.6, here in the region of the air channel 4A. The water is heated in such a way that water vapor is formed, wherein the water vapor is supplied to the air supply 3 via an undesignated conduit.

[0174] The heated air and the generated water vapor are mixed, and the mixture is fed via the chamber end 3.3 to the cavities formed in the adapters and is conducted via these to the UVC radiation sources.

[0175] The air enriched with moisture smooths the object to be cleaned, eliminating the need for subsequent ironing.

[0176] The additional use of a special ironing liquid is also possible, so that instead of water the ironing liquid is filled into the schematically indicated water tank 7.

[0177] The smoothing of the objects by means of steam is preferably carried out after the UV radiation sources have been switched off and thus after the object has been treated with UV radiation.

[0178] For more effective cleaning, the air in the area of the air supply 3 is heated or cooled as already described or alternately heated and cooled. For this purpose, the heating device 3.4 is arranged in the area of the air supply 3. Alternatively, a fan heater can also be used as a combination of heating device 3.4 and fan 3.2. The air flowing through the air supply 3 is heated or cooled in the area of the heating device 3.4. The temperature is adjustable and/or variable in a temperature range from −50° C. to 100° C., preferably in a temperature range from −30° C. to 60° C., particularly preferably in a temperature range between −10° C. and 50° C.

[0179] In a further design, a fragrance capsule 8 is arranged in the region of the air supply 3 for generating a fresh fragrance of the objects into the air supply 3. The released fragrances can be added with the air sucked in by the air supply 3 and fed into the chamber 2 (main chamber or cleaning chamber).

[0180] According to the preceding figures, the chamber 2 (main chamber or cleaning chamber) according to the exemplary embodiment in FIGS. 5 and 6 comprises a suction device 6 in the ceiling area of the chamber 2. The suction device 6 is preferably arranged in the upper region of the device and has an air outlet 6.1 directed upwards and outwards, in which likewise a fan (not shown) is provided. The suction device 6 can also be supplemented with a replaceable filter, not shown, so that the polluted air can be cleaned and the ozone removed before it exits the chamber. The filter is preferably arranged in the area of the fan and the suction device 6.

[0181] Also according to FIGS. 2 and 3, an alternating pressure can be achieved in the chamber 2 with the suction device 6 and the air supply 3, wherein the suction device 6 can be designed in such a way that a vacuum can also be generated in the chamber 2. For such a design, the chamber 2 is preferably air-tight.

[0182] From FIG. 3 it can be seen that the suction device 6 with one or more air outlets 6.1 can also be arranged in the lid D. In this case, there are outlet openings 6.1.1 in the undesignated upper side of the cabinet body 1a, through which the extracted air can escape. In the inserted state of the housing 1, the outlet openings 6.1.1 of the cabinet body 1a are located above the air outlets 6.1 in the lid D of the housing 1.

[0183] Furthermore, it is possible to arrange an additional pressure system 11 in the area of the base B of the chamber 2, by means of which the air supply 3 and the suction device 6 are supported to generate a negative or positive pressure.

[0184] The pressure in the chamber 2 can be adjustable and/or variable in a pressure range between 0.001 bar and 10 bar, in particular between 0.1 bar and 2 bar.

[0185] The use of a filter is particularly recommended as even low concentrations of escaping ozone are harmful to health due to irritation of the respiratory tract.

[0186] FIG. 4 shows a representation of a box RB, similar to FIG. 6 but without a lid in the insertion and instead with cross-struts 12 between the sides S1 and S2, which stabilize the sides S1, S2 relative to each other and ensure that the objects to be cleaned do not protrude laterally from the housing 1 and prevent them from being inserted into the body. It is possible here to insert the objects to be cleaned from above.

[0187] The suction device (not shown here) is then arranged in the front side part S2 as in FIG. 1 or also in the rear side part S2, in which case corresponding air outlets are then present in the cabinet body 1a in the rear wall.

[0188] In this variant, it is indicated that the first and second adapters 4.5 and 4.6 are detachably connected to the air channel 4A of the main body 4.

[0189] Instead of cross-struts, one or more plate-like elements may extend between side parts S1, S2.

[0190] Such cross-struts or plate-like elements can also be used in the variants described above.

[0191] Furthermore, it is possible according to FIG. 7 that, for example, the first adapter 4.5 has a joint G1 and G2 in each of the two upwardly extending regions of the air guides 4.5.1. The region shown here extending vertically upwards, for example in an initial position, is thereby designed to be pivotable about a horizontal axis A1, A2, which is indicated by the double arrows. As a result, the upper ends of the two air guides 4.5.1 of the adapter 5.5 can be pivoted towards and away from each other, and thus their distance can be adapted to the objects to be accommodated.

[0192] With the device according to the invention, the air flow supplied to the chamber 2 (main chamber or cleaning chamber) is divided in the chamber via the channels formed by the adapter elements and is guided in each case to a UV radiation source 5.

[0193] The number of channels formed in an adapter corresponds to the number of UV radiation sources 5 provided on the adapter.

[0194] It is thus also possible to provide a main body 4 or adapter not only with two, but also with three, four or more upwardly extending branches, each of which guides the air flow to a UV radiation source 5.

[0195] Preferably, the UV radiation sources 5 are located at the air outlet areas of the adapters.

[0196] The adapters also form the receptacles for the objects to be cleaned.

[0197] The adapters can be designed in such a way that the distance between the upper areas that receive the objects to be cleaned can be changed.

[0198] It is possible to arrange several of the substantially parallelepipedal devices according to the invention side by side and/or one above the other in a battery-like manner. The devices can also be connected to each other.

[0199] Furthermore, it is also alternatively possible to provide a cabinet body with a pivotable or laterally displaceable door, in which case the chamber/cleaning chamber is formed in the cabinet body.

[0200] Depending on the object to be cleaned, the individual parameters such as pressure, temperature, UV radiation and ozone can be set. For example, when cleaning leather, it is advisable to use the maximum power of the device, while cashmere, for example, should only be treated gently.

[0201] In FIGS. 5 to 7, a further variant of a device according to the invention is illustrated. Here, no housing 1 is provided which can be pushed into a cabinet body 1a of the box RB, but the housing 1 forms the cabinet body 1a. The chamber 2 (main chamber or cleaning chamber) is thus not withdrawable here, but is formed in the cabinet body 1a. The device thus has a body 1a in which the chamber 2 (cleaning chamber) is formed. Here, two main bodies 4 are provided in the chamber 2 for receiving objects, namely a first main body 4.5 for accommodating a pair of shoes or a pair of gloves or protective masks and a second main body 4.6 for accommodating clothing in the form of shirts, gowns, jackets and the like. The first and second main bodies 4.5, 4.6 are hollow and have an air supply in their interior leading through the hollow structure which is not visible. The air stream flowing in via a conduit can be divided into a first and a second air stream for each adapter 4.5, 4.6 and flows past the UV lamps of the adapters 4.5, 4.6 which are not visible here and are not designated. These UV lamps are arranged at outlet regions of the adapters 4.5, 4.6, so that the air flow emerging from the adapters 4.5, 4.6 flows past the UV lamps.

[0202] The first main body 4.5 branches upwards into two unnamed adapter elements with outflow openings (not shown) in which UV-C lamps are arranged and has a size which allows a pair of shoes, gloves, protective masks and the like to be positioned on it, so that the UV lamps are at least partially located in the objects to be cleaned and the air flow emerging from the first adapter 4.5 penetrates the object with the ozone formed by the UV lamp and possibly also penetrates it (in the case of textile material).

[0203] The second main body 4.6 is also of hollow design and has a bow-shaped design in its upper region, so that a shirt, a jacket, a smock, items of Table 2 and the like can be hung up above it. For this purpose, two projections V facing laterally away from each other and angled downwards with undesignated openings extend on the upper region of the second main body 4.4, in which the UV-C lamps are arranged.

[0204] Preferably the second main body 4.6 can be pulled out of the device in the direction of the bold arrow, for example, via an upper rail-like suspension 13 (see FIG. 10), so that the clothing or other objects can be better positioned above it. At opposite projections V of the hanger-shaped region there are undesignated outlet openings, and within each end there is a UV lamp. After receiving the objects, the second adapter 4.6 is pushed back into the device. During cleaning operations, the air flow is directed into the second hollow shaped adapter 4.6 either from above or from below, flows past undisclosed UV lamps and out of the outlet openings in the bracket shaped area. Two upwardly facing projections V are additionally provided on the lower region of the second main body 4.6. These have lateral slots 4.6″ through which ozone-enriched air can flow into the chamber 2. In the case of longer items of clothing, this also ensures cleaning of the lower region if these reach over the lower projections V.

[0205] A second chamber 2.2 extends below the chamber 2 and laterally thereof in the body 1a. The second chamber 2.2 is separated from the second chamber 2.2 by a horizontal wall W1 and a vertical wall W2. Below the second chamber 2.2 a third chamber 2.3 is arranged, which is separated from the second chamber 2.2 by a horizontal wall W3. Above the first chamber 2 and the vertical region of the second chamber 2.2 is a fourth chamber 2.4 separated therefrom by a horizontal wall W4. Below the third chamber, the cabinet body has a base 1B, a rear wall 1R, a lid 1d, two side walls 1S (only one of which is visible) and a door (not shown here) arranged below the display 9.

[0206] In order to be able to represent the interior design of the device, a side wall and the door were not drawn in.

[0207] Laterally in the lower area of the third chamber 2.3 there are recesses 3 for the air supply. In the lower third chamber 2.3 there is further provided an air supply 3.1 in the base 1B and an inlet pump or fan 3.2. An inlet regulation 3.3′ leads to the second chamber 2.2 from the third chamber 2.3 and via this the air supply, not designated here, into the second chamber 2.2. The air is heated in the second chamber 2.2 by means of a heating element 3.4 to the desired/preset temperature. The air flows in the lateral area of the second chamber 2.2 upwards into the fourth chamber 2.4 and in the vertical separation W3 between the chamber 2 and the second chamber 2.2 there are apertures 2.2′ through which a part of the sucked air can enter the chamber 2.

[0208] The aspirated air is guided into the interior of the main bodies 4.5, 4.6. This is carried out either from below from the second chamber 2.2 via a supply line 3.5 (shown here dashed) or from above from the fourth chamber 2.4 via a supply line not shown here. In the base or the horizontal wall W3 of the second chamber there are openings 14 through which water vapor can be supplied for smoothing the objects. This is preferably supplied under pressure from an evaporator 7.3 provided for this purpose. Water is supplied to the evaporator 7.3 from a water tank 7, which is arranged here in the upper fourth chamber 2.4 and is connected to the evaporator 7.3 via a conduit not shown. The hot water vapor additionally serves to kill viruses, bacteria, fungi and other germs.

[0209] Furthermore, openings 14.2 may be provided in the bottom (wall W2) of the chamber 2 for generating a circulating air between the chamber 2 and the second chamber 2.2. Furthermore, a connection 15 for a vacuum pump is provided in the third chamber 2.3, by means of which a vacuum can be generated in the chamber 2. The vacuum is formed in the chamber 2 and in the second chamber 2.2.

[0210] As in the example described above, a fragrance capsule 8 is also provided, here arranged in the fourth chamber 2.4 (optional).

[0211] The electronics are also located in the fourth chamber 2.4 and the control unit 9 with a corresponding operating display is provided on the front side thereof. The lid 1D of the fourth chamber 2.4 is preferably pivotable upwards. Openings 16 are arranged in the lid 1D, which serve to cool the electronics and in/under which one or more fans may be arranged.

[0212] The chambers, at least chamber 2, are closed in an airtight manner, preferably via a door with an appropriate closing mechanism.

[0213] The temperature in the second chamber is also in a temperature range of −50° C. to 100° C., preferably in a temperature range of −30° C. to 60° C., particularly preferably in a temperature range between −10° C. and 50° C.

[0214] The pressure in the chamber 2 can also be adjustable and/or variable in a pressure range between 0.001 bar and 10 bar, in particular between 0.1 bar and 5 bar.

[0215] A plurality of first and second adapters may also be provided in this embodiment variant according to the invention.

[0216] It is particularly advantageous here that the main body parts can be pulled out of the device, whereby they can be very easily fitted with the object to be cleaned in the form of jackets, gowns and the like.

[0217] FIG. 7 shows the air flow (in the device). The air enters the third chamber 2.3 (main flow L1—through line) and passes via the inlet regulation 3.3 into the second chamber 2.3. From there this is divided into [0218] a first air flow L4.5 (shown dashed), which leads from below into the first main body 4.5, [0219] a second air flow L4.6 (dash-dot line), which leads from below into the second main body 4.6, [0220] a third air flow L2 (thinner through line), which is led laterally upwards via the second chamber 2.2 and enters the first chamber 2 laterally via the apertures and ventilation slots, [0221] a fourth air flow L4 (represented by the bold arrows) which creates a circulation of air between the first chamber 2 (main chamber/cleaning chamber), the second chamber and the fourth chamber L.4, preferably when there is no vacuum in the chamber 2 and the second chamber 2.2.

[0222] The second air flow L4.5 emerges from through-flow openings (not designated) of the first main body 4.5 after passing the UV lamp (not shown).

[0223] After flowing through the second main body 4.6, the third air flow L4.6 also exits at outlet openings in the projections V in the upper region or next to the projections V located here at the bottom in the area of the UV lamps.

[0224] As already described above, the main bodies 4 (4.5, 4.6) can be of different design and also several different ones can be integrated in one device, preferably interchangeably.

[0225] This is then implemented via an interface between main body 4, 4.5, 4.6 and cabinet body or device, wherein the interface is intended to ensure easy removal of a main body and insertion of a new main body.

[0226] The interface is preferably designed in the form of a rail system by means of which the receiving element 4 (4.5, 4.6) can also be pulled out of the device or the box/cabinet body to such an extent that it can be easily loaded with the objects to be cleaned or in order to remove the cleaned objects.

[0227] Alternatively, the air flow may enter the chamber 2 through a double lateral wall of the chamber and enter the adapters, which are rotated 90° and guided as in the previous text.

[0228] In FIGS. 8 to 11, two different main bodies 4 are shown by way of example, which have a plurality of receptacles in the form of projections V arranged opposite one another and one above the other.

[0229] According to FIGS. 8 and 9, a hollow and vertically extending main body 4 has on opposite sides 4.7a a plurality of projections V extending laterally and obliquely upwards. The projections V are each formed here in pairs in the form of mutually parallel webs 4.7.2 (see FIG. 12). A slot-like aperture 4.7.3 is present in each web.

[0230] A through-flow opening 4.7.4 is present in the respective side 4.7.a of the main body 4 between each two webs 4.7.2 arranged in pairs. Furthermore, the UV radiation source 5, preferably a UVC lamp, is arranged between the two webs 4.7.2.

[0231] Between the two sides 4.7a a front side 4b and a rear side 4.7.c extend respectively.

[0232] Preferably, front side 4.7b and rear side 4.7c with the adjoining webs are cut from one plate and are spaced apart from each other over the sides 4.7.a.

[0233] Front side 4.7b, rear side 4.7c and sides 4.7.a are preferably made of wood, in particular plywood, and joined together—glued and/or screwed—so that the hollow body is formed in the shape of the main body 4.

[0234] On the upper side of the third adapter 4.7 there is a rail 17, via which the third adapter 4.7 can be connected to the cabinet body not shown here and can be pushed into and out of it. Furthermore, at the upper end there is an inlet opening 18 through which air flows into the third adapter 4.3 during operation.

[0235] During the cleaning process, air thus flows via the inlet opening 18 into the main body 4 into its cavity and via the through-flow openings 4.7.4 to the outside and thereby past the UV radiation sources 5 and between the projections 4.7.1 and thus the webs 4.7.2 and their openings 4.7.3. If one or more objects are placed above one or more projections V, these objects are reliably disinfected by the ozone-carrying air stream and the UVC light, optionally in conjunction with a set temperature and/or a pressure, preferably a negative pressure, in the chamber 2 (cleaning chamber) not shown here.

[0236] FIGS. 10 and 11 show a detailed diagram of a further variant of a main body 4 for one or more objects according to FIG. 7, in which the rails are not shown.

[0237] This is also designed as a hollow body and is composed of panels, in particular of wood or plastic, but preferably of plywood.

[0238] It has sides 4.6.a and a front side 4.6.b and a rear side 4.6.c which are joined together. In the front side 4.6.a and the rear side 4.6.b, apertures are arranged in the upper area as inlet openings 18.

[0239] The front side 4.6b is thereby preferably detachably connected to the sides 4.6a. Here, too, the main body 4 has projections V. The projections V adjoin the main body 4 in pairs. In this case, two projections V are arranged facing away from each other, opposite each other in the upper region, and two projections V are arranged facing away from each other, opposite each other in the lower region of the main body 4. The two upper projections V are angled slightly downward in opposition to each other so as to form a hanger-shaped receptacle for garments in the form of jackets, coats, gowns and the like. The two lower projections V project upwardly and outwardly at an angle. In the area of the projections V, the UV radiation sources 5, which are shown here as dashed lines, are arranged. Preferably, these are located within or in the region of through-flow openings of the main body not shown here in front of the projections V. In the projections V, apertures not visible here are arranged through which the air flows out.

[0240] Shoes, gloves, respiratory masks and the like can be positioned above the lower projections.

[0241] In the case of longer garments that extend over the lower projections V, the garments are also disinfected safely and reliably on/in their underside.

[0242] Cables run inside or along the outside of the main body 4, via which the power supply to the UV radiation sources 5 (preferably UVC lamps, in particular UVC LEDs) is implemented. This is also implemented in this way in the other designs of main bodies. Otherwise, the structure of the main body 4 corresponds to the design shown in FIG. 5.

[0243] Preferably, the interfaces of receiving elements to the cabinet body 1a are designed the same for the different main bodies in order to ensure their interchangeability.

[0244] In FIG. 12 it is indicated that the main body 4, which is in the form of a hollow body, can be formed from two half shells 4a, 4b.

[0245] FIG. 13 shows as a principle sketch that the main body 4 is composed of a half shell 4a and a plate 4c.

[0246] Both parts (half-shells) 4a, 4b, or 4a, 4c are joined together, e.g. non-detachably by gluing or welding or also by means of a detachable connection, in the case of plastic for example by a clip system or in the case of sheet metal e.g. by screw connections.

[0247] In this case, the main body 4 is made of plastic or sheet metal, for example, and the half-shell is made by deep drawing, for example.

[0248] If plastic is used, the receiving element could also be produced in one piece by blow molding.

[0249] FIG. 14 shows the device in the form of a box RB whose cabinet body 1a can be closed at the front by means of a door 19, in the open position of the door 19. It can be seen in the box RB a main body 4 arranged in the chamber 2.

[0250] According to FIG. 15, the main body 4 has been pulled out of the chamber 2 by means of rails 17 and can now be loaded. The front side 4.6b and the rear side of the main body 4, which is not indicated here, are aligned substantially parallel to the side walls 1S of the cabinet body 1a of the box RB. After the second main body 4 has been pushed back into the chamber 2, the door 19 is closed (preferably in an airtight manner) and the parameters required for cleaning can be set and the cleaning process started via the display 9 of the control unit. Alternatively, it is possible to use an app via a mobile device (e.g. laptop or smartphone) to set, start and stop the cleaning process and also to lock, unlock and inform the cleaning device of the status and completion of the cleaning process.

[0251] FIG. 16 shows a further variant of a box RB, in which a main body is aligned with its front side 4.6b substantially parallel to the rear wall 1R of the cabinet body 1a, in comparison with FIGS. 14 and 15. Again, the main body 4 may be replaceable and/or withdrawable from the device via an interface, although this is not shown. The box RB also has here a preferably hinged lid 1D, which allows access to exchangeable functional elements in the upper fourth chamber not designated here. Input is provided via the display 9. The front is formed by a hinged door 19. This can be made here and also in the aforementioned exemplary embodiments of UV-stable material, preferably plastic, polymer mixtures, coated glass or of metal or wood. The main body 3 is also designed as a hollow body and is preferably formed in two layers (from two half shells). In the area of the UV radiation sources, the adapter 4.6 has air outlets in the article made of textile material, which is not shown here, however.

[0252] A double-walled rear wall 1R with adapted air apertures 2.2′ to the chamber 2 is provided. In the double-walled side walls 1S there are likewise air apertures 2.2′ to the chamber 2. Furthermore, there is an additional outlet for, for example, water vapor 14 in the bottom of chamber 2.

[0253] In a side wall 1s there is an air inlet 3.1 at the bottom and an air outlet 6.1 at the top. This constructive design of the device, in particular of the cabinet body, can of course also be provided for a different design, arrangement or accommodation of the main body.

[0254] In particular, when a negative pressure is generated in the chamber 2, it is advantageous if the air can be exhausted via the double rear wall 1R the double side walls 1S via the air apertures.

[0255] It is also possible to introduce hot air into chamber 2 via the air openings 2.2″.

[0256] The generation of negative pressure in chamber 2 and the introduction of hot air into chamber 2 do not occur simultaneously.

[0257] A further design of the main body 4 is provided in FIG. 20 in front view, in FIG. 21 in top view (shown enlarged) and in FIG. 22 when arranged in the chamber 2 of a box RB.

[0258] The main body 4 is formed in the shape of a tubular hollow body, on the circumference of which a plurality of projections 4V each extend in a plane, and a plurality of projections 4V are arranged one above the other. The projections V face obliquely outwardly and upwardly. Each projection 4V adjoins an aperture of the main body 4, which is not shown here. A UV radiation source 5, in particular a UVC lamp (preferably a UVC LED), is arranged within each projection V, which is indicated here by dashed lines. The projections V have openings 4.8.3 and are open at their free end.

[0259] The air supply is provided at the bottom or top of the adapter 4.8. The air flows into the main body 4 and through its through-flow openings, not visible and not designated here, into the projections V, past the UVC radiation sources 5 and through the projections V open towards the front and their openings 4.8.3.

[0260] According to FIG. 19, the main body 4 arranged in the chamber 2 is rotatably mounted at its lower end for loading (here from the direction of the arrow).

[0261] It is also possible that the main body 4 also rotates during cleaning in the chamber 2. In this case, a rotary drive is operatively connected to the main body 4 and the power supply to the UV radiation sources must also be ensured during rotation (e.g. via sliding contacts or via cables and a back and forth rotation with a rotation angle of less than 360°).

[0262] By rotating the main body 4 during cleaning, faster drying, better removal of dirt and better removal of allergy-causing pollen can be realized.

[0263] Especially when cleaning shoes, the centrifugal force occurring during the rotation promotes the preservation of the shoe shape.

[0264] Here, too, as an alternative or in addition to the rotatable mounting in the chamber, the extraction can be provided by means of a rail system, which may also be arranged at the bottom of the receiving element.

[0265] In the presented embodiment variants, the projections V can be formed integrally with the main body of the receiving element or can be detachably or non-detachably connected to the receiving element. A detachable connection enables the projections to be replaced.

[0266] FIGS. 20 and 21 show a device in the form of a box RB with a cleaning chamber K in which a plurality of tubular main bodies 4 are arranged, which are arranged next to one another and extend vertically upwards and, here by way of example, are connected to one another at their lower ends by a connecting line 20.

[0267] Next to the cleaning chamber K is a technical chamber T, in which all technical components such as control unit, pump(s), filter and the like are arranged.

[0268] The connecting pipe 20 is composed of a plurality of pipe sections 21 and T-shaped fittings 22 (pipe connectors). The T-shaped fittings 22 have connections on both sides to the pipe sections 21 and a connection, facing upwards here, to a respective tubular main body 4. At its end facing away from the technical chamber, the connecting pipe 20 is supported by means of a foot 23 at the bottom on the base of the box RB, which is not designated, and in the direction towards the technical chamber T, the connecting pipe 20 is connected to the partition wall to the technical chamber T, which is not designated, via a connecting flange 24. In the region of the connecting flange 24, an aperture is arranged in the partition wall, so that a pump and/or vacuum pump (not shown) is connected to the connecting pipe 20, so that air flows into the connecting pipe under pressure via the pump(s) or air is extracted. In the technical chamber T there is an aperture 25 through which air can flow in or out. Furthermore, an air flow inlet 25.1 leads from the technical chamber T through the partition wall to the cleaning chamber K, which is not designated.

[0269] Control knobs 26 are provided in the front of the technical chamber T.

[0270] Three tubular main bodies 4, shown here on the left, extend substantially continuously upwardly from the connecting pipe 20. Each of the three main bodies 4 shown here on the left has, in the upper region in the direction of the front and in the direction of the rear of the box RB, downwardly angled projections V in the form of 90° angle pieces 27, into which UVC lamp means 5 are screwed so as to project downwardly. On these main bodies, for example, jackets or gowns can be hung. Somewhat below the UVC lamps 5, there are further flow-through openings 4.7.4 in the tubular main body 4, which are formed in cross-shaped fittings 28. Each cross-shaped fitting 28 has four connections. A lower and an upper fitting are connected to vertically extending pipes of the main body, the second lateral fittings are open so that air can flow out of them.

[0271] Garments such as jackets or gowns can be hung over the left-hand main bodies 4 with their projections V, for example.

[0272] Two tubular main bodies 4 are shown on the right, consisting of shorter pipe sections 21 connected to each other. Three rows of horizontal pipe elements of T-shaped fittings 22, 90° elbow fittings 27 (angled upwards) and cross-shaped fittings 28 each with three upwardly facing projections V with undesignated through-flow openings, into which UVC lamps 5 are screwed, extend from vertical tubular pieces 21. These serve, for example, to receive smaller objects such as breathing masks and the like. The doors are not shown in FIGS. 20 and 21.

[0273] FIG. 22 shows the device according to FIGS. 20 and 21 from a different perspective with undesignated doors and an exemplary gown J or jacket positioned above the main body 4.

[0274] It is of course possible to arrange more or less of the main bodies in a box and to design the structure of the main bodies and the number and orientation of the projections V with the UVC lamps as desired.

[0275] FIGS. 23 and 24 show a device which is substantially as in FIGS. 20 to 22, but with only three main bodies 4 which have projections V arranged one above the other and side by side and facing upwards, like the two right-hand main bodies 4 shown in FIGS. 20 to 22.

[0276] Also in the variant according to FIGS. 23 and 24, the main bodies 4 are composed of several pipe sections and pipe connecting elements. These are pipe sections 21, T-shaped fittings 22, 90° angle pieces 27 and cross-shaped fittings 28. The 90° angle pieces 27, which are angled upwards, form upwardly facing projections V into which the UVC lamps 5 are screwed.

[0277] Above the UVC lamps 5 located at the top, additional angle pieces 27 are arranged here, the flow openings 4.7.4 of which face downwards.

[0278] The other angle pieces 27, which support the UVC lamps 5, also have unmarked through-flow openings in the direction of the UVC lamps 5. In the intermediate wall (not designated) between the cleaning chamber K and the technical chamber T there are an air flow inlet 25.1, a filter battery and an exhaust air system 29 as well as a circulating air generator and heating element 30 (see FIG. 23).

[0279] Again, the number and design of the main bodies 4 and the number, design and orientation of the projections V and the number and orientation of the UVC lamps 4 can be designed to suit individual requirements.

[0280] In FIG. 25, a device is shown which has only a cross-shaped hollow main body 4 formed by a cross-shaped fitting 28. There are three upwardly facing projections V. The left and right projections V are each formed by angled pieces 27 screwed into lateral connections of the main body 4 and angled upwardly. The middle projection V is formed by the upwardly facing connection of the main body 4. The upwardly facing projections V of these pipe connecting elements have through-flow openings 4.7.4. In these through-flow openings 4.7.4 adapter elements 31 are inserted, which accommodate the UVC lamps 5 and which are provided with slots 32 through which the air flow can exit to flow past the UVC lamps. The UVC lamps 5 are arranged in the three adapter elements 31 of the projections V.

[0281] An aperture 25 is arranged in a side wall of the box RB, which forms an air flow inlet. A recirculation channel 33 opens into the intermediate wall to a technical chamber not shown here on the rear side.

[0282] The main body V is attached by means of an angle piece 27, which adjoins the downwardly facing connection of the cross-shaped fitting 27 and is attached to the rear wall of the box RB by means of a connecting flange 24. In the rear wall, an aperture not visible here is provided in this area, through which air flows into the main body 4, which flows past the UVC lamps 5 via the projections V and the adapter elements 31. Only a control knob 26 for switching on and off is provided on this device. The box RB can be closed with an undesignated door during the cleaning process.

[0283] FIG. 26 shows a partial view of the device according to FIG. 25 with objects to be cleaned in the form of breathing masks M received by two UVC lamps 5.

[0284] FIG. 27 also shows a main body 4 arranged in a box RB, which has three upwardly directed short projections V with through-flow openings 4.7.4 and adapter elements 31 with slots 32 seated therein. The main body 4 has been produced here, for example, by 3D printing or injection molding.

[0285] Here, too, the UVC lamps 5 facing upwards are fixed in the adapter elements 31, above which, for example, breathing masks can be positioned.

[0286] Several hooks 34 are provided at the front of the main body, on which objects to be cleaned, such as respirator masks, can be accommodated.

[0287] The projections V have through-flow openings 4.7.1 to the individual adapter elements 31 on their upper side.

[0288] An aperture 25 is provided in a side wall, which forms an air flow inlet, and a recirculation channel 33 opens into the rear wall of the cleaning chamber K. An undesignated lockable door is also provided. There is also only one control knob for starting and stopping the cleaning process.

[0289] It is also possible that the control button is only used to start the cleaning process and that this process is automatically ended after a certain time.

[0290] The adapter elements used in FIGS. 25 and 27 can also be used in the other solutions described above, in particular in the variants illustrated in FIGS. 17 to 24.

[0291] In particular, due to the modular design, which is possible by using pipes, pipe sections, pipe connecting elements, the devices can be designed variably with regard to the number and size of the main bodies, the number and arrangement of the UVC lamps.

[0292] It is possible to provide a modular system with which the device can be adapted to individual requirements.

[0293] The solution according to the invention enables for the first time a versatile possibility of accommodating a wide variety of objects to be cleaned in a corresponding device, as well as their efficient cleaning and elimination of pathogens.
