[0032] With reference to the aforementioned figures, the tableware hydro-cleaning apparatus of the present invention, generally indicated with the reference numeral 10 in the aforementioned figures, substantially comprises two units defined by a first unit 12 and by a second unit 14 not rigidly connected to each other, separable, movable and positionable/repositionable independently with respect to each other.

[0033] The first unit 12 defines a control unit which houses the components/devices required for the operation of the hydro-cleaning apparatus, with said components housed in single and separate compartments, said components/devices housed in said compartments and comprising a pump 13 (preferably of the diaphragm type and, preferably, a pump operating at a pressure of 3-9 Bar, a flow rate of about 4-4.5 Litres/minute and a temperature comprised between 60 and 65° C.), a transformer 15, a socket or terminal 11 for connection to the power supply mains and an on/off switch (the transformer being suitable to supply the pump 13), a duct or cannula 16 provided with a nozzle 17 (for example of the shower-head type or with a flat blade type or of another type suitable for the purpose) connected to the pump 13 for spreading a washing liquid on the tableware (as detailed hereinafter) and a container 20 comprised in the volume of the first unit 12 that is slidable and partially extractable and positionable/orientable with respect thereto (for the loading of the water and washing detergent).

[0034] The container 20 externally comprises a handle 20′ (or a knob or an equivalent grip means) to allow the extraction of the container when using the hydro-cleaning apparatus and so as to allow the repositioning thereof when the apparatus is not in use.

[0035] Said container 20 can provide for the possibility of being extracted with respect to the first unit 12 and oriented with respect thereto in order to be able to adapt to all the configurations of positioning the tap of the sink or the overall dimensions of the sink, as schematically shown in FIG. 4.

[0036] In this case, the container comprises a rotational constraint connection (of the hinge type or similarly known and suitable for the purpose) with respect to the first unit 12 which allows a rotation of said container with respect to the first unit 12 (according to a vertical rotation axis) once said container 20 is extracted with respect to said first unit 12; in particular, the container 20 is extracted with respect to the first unit according to a longitudinal extension direction of said container (direction indicated by the arrow “X” in FIG. 3 and FIG. 4) and, once extracted (at the end of the stroke thereof), said container 20 can be rotated by 90° with respect to the first unit, to the right or to the left, so as to be able to achieve, as a whole, a rotation by 180° (it is to be understood that the container can also be rotated and positioned in all positions included in a 180° angle, in order to be able to orient the container 20 as a function of the position of a tap 44 of a sink 40).

[0037] Also arranged inside the first unit 12 is a means or device 50 for supplying the detergent (typically tableware liquid soap) to be mixed with the water of the container 20, with said device 50 which comprises a manually controlled valve 51 which comprises a plunger 51′ comprising: in the preferred embodiment, an elastic return spring (not shown) (however, the return to the “zero” position of said plunger 51′ can also be actuated manually or with a mechanism of the “interlocking” type), with said plunger 51 which, when (in the preferred embodiment shown in the figures) is pulled/moved upwards (in a vertical direction as indicated by the arrow “K” of FIG. 5), allows the descent—by gravity—of the detergent contained in a compartment 51″′ which is mixed with the water of the container (water and soap mixture—as indicated by the conduit 52 of FIG. 5) and which is drawn from the pump 13 and conveyed to the duct or cannula 16 (as indicated by the conduit 54 of FIG. 5) and which—when released—returns to the initial position due the return action of the spring and so as to shut/interrupt the supply of the soap to the container 20; the actuation of said valve, as indicated previously, is of the manual type and it is carried out by means of a knob 51″ which, in the preferred embodiment of the figures, allows the gripping to manually lift said plunger.

[0038] The container 20 further comprises an “overflow” valve 54 with the function of indicating an excessive filling of the container 20 by the water coming from the tap 44.

[0039] According to the preferred embodiment, the functional components described above and housed in the first unit 12 are tendentially arranged according to horizontal planes parallel to each other in a configuration of the “tower” type, in order to reduce the overall dimensions of the aforementioned first unit 12, with said first unit 12 which, as schematically shown in FIG. 2, is arranged beside and adjacent to the second unit 14.

[0040] FIGS. 7 to 9 illustrate an alternative embodiment of the hydro-cleaning apparatus of the invention, indicated in its entirety with 10′ and in which the details shared with the aforementioned preferred embodiment (FIGS. 1 to 6) are indicated using the same numerical reference.

[0041] The first unit 12′ houses the components/devices required for the operation of the hydro-cleaning apparatus housed in single and separate compartments and, as in the aforementioned case, these components consist of a pump 13 (similar to the one described with reference to the preferred embodiment), a transformer 15, a socket or terminal 11 for connection to the power supply mains and an on/off switch, a duct or cannula 16 provided with a nozzle 17 (for example of the shower head type or with a flat blade or of another type suitable for the purpose) connected to the pump 13 for spreading a washing liquid on the tableware (as detailed hereinafter) and a container 60 comprised in the volume of the first unit 12′ that is slidable and partially extractable by means of a handle or gripping element 60′ and positionable/orientable with respect to said first unit in a manner similar to the one described above with reference to the preferred embodiment (therefore, it is not described in further detail.)

[0042] According to the alternative embodiment, the means or device 50 for supplying the washing detergent has the same characteristics as in the preferred embodiment, with the difference lying in the fact that it is housed differently in the first unit 12′ and, more particularly, it differs from the manual actuation of the plunger 51 which, tendentially, will move according to a horizontal axis.

[0043] According to such embodiment, the components inside the first unit 12′ are arranged according to a substantially horizontal plane.

[0044] The second unit 14 defines the tableware washing chamber which is completely similar to the second unit according to the preferred embodiment described with reference to FIGS. 1 to 6 and it is therefore not the subject of further description.

[0045] With reference to the alternative embodiment, the first unit 12′ is configured to define a support base for the second unit which is positioned above said first unit 12′, as schematically shown in FIG. 7.

[0046] FIGS. 1 and 2 schematically illustrate the tableware hydro-cleaning apparatus of the present invention when arranged on a conventional kitchen sink 40 or the like.

[0047] In particular, FIGS. 1 and 2 illustrate hydro-cleaning apparatus comprising the first unit 12 with a tower-like configuration, with the second unit 14 arranged adjacent to said first unit 12.

[0048] FIG. 9 illustrates the tableware hydro-cleaning apparatus of the present invention, according to the alternative embodiment, when arranged on a conventional kitchen sink 40 or the like.

[0049] The hydro-cleaning apparatus, when in use for washing tableware arranged in the washing compartment 22 of the second unit 14, is arranged on a dripping surface 42 of the sink 40 with the cannula 16 provided with the nozzle 17 which is positioned in correspondence with the second unit 14 with the nozzle 17 arranged above the washing compartment 22 and with the container 20 and the drain valve 30 arranged in an position for the outflow, respectively, from the first unit 12 and from the second unit 14.

[0050] Once extracted with respect to the first unit 12 (12′), the container 20 (or 60) is oriented as a function of the position of the tap 44 of the sink 40.

[0051] For washing the tableware, the hydro-cleaning apparatus is connected to the power supply mains, the container 20 (60) is filled with water coming from a tap 44 of the sink 40 and the manual valve is actuated for the outflow of the detergent from the dedicated reservoir and, once the operation of the first unit 12 (12′) has been activated by means of the on/off switch 56, the user manually orients the washing nozzle 17 to facilitate an accurate cleaning of the dishes in the washing compartment 22.

[0052] Once the washing operation has been completed, the first unit 12 (12′) is switched off by means of the on/off switch with the waste water which is expelled through the drain valve 30. During the tableware washing step, the tap remains open to maintain an adequate and sufficient level of water in the container 20 (60); however, according to an alternative embodiment, the container 20 (60) is dimensioned according to the sufficient amount of water to carry out a complete washing and, in this case, the container is filled and then the tap is subsequently shut.

[0053] Once the washing has been completed and when the hydro-cleaning apparatus is not in use, it can be displaced and kept in a place at will, thus vacating the space on the sink. The washing operation by means of the hydro-cleaning apparatus of the invention requires about 60 to 120 seconds with a consumption (from experimental tests conducted) comprised between about 4 and 8 litres; tests conducted found that the washing time is about 1-2 min with a water consumption of less than 5 L per minute.

[0054] The advantages attained by the hydro-cleaning apparatus of the present invention are observable in the light of the above.

[0055] The tableware hydro-cleaning apparatus of the present invention has the advantage of being compact and small in size and the two units it consists of, separate with respect to each other and positionable and repositionable, allow an easy adaptability of the apparatus to sinks of different types and sizes.

[0056] Further advantageous is the fact that the two units (first unit and second unit) that the hydro-cleaning apparatus consists of, being separate from each other, allow to reduce space even when the hydro-cleaning apparatus is not in use.

[0057] A further advantage of the hydro-cleaning apparatus of the invention lies in the fact that being separate from the first unit, the second unit (which defines the washing chamber) can be easily washed (to eliminate any stains or lime residues that can be formed after several washing cycles). In addition, it is easy to dry so it can be repositioned when not in use.

[0058] Further advantageous is the fact that in case of malfunction or failure even just one of the two units can be replaced, with an ensuing saving in terms of costs.

[0059] A further advantage lies in the fact that the hydro-cleaning apparatus of the invention allows to carry out a complete washing in short times ranging from 1 to 2 minutes with a very low water consumption and less than 5 litres per minute.

[0060] Though the invention has been described above with reference to the embodiments thereof provided solely by way of non-limiting example, numerous modifications and variants shall be clear to a man skilled in the art in the light of the description above. Thus, the present invention protects all modifications and variants that fall within the scope of protection of the claims that follow.
