Finally, FIG. 4 shows the mobile cleaning unit 410 populated with the various components in a side view. These figures will be discussed collectively below.

[0128] The mobile cleaning unit 410 illustrated in a side view in FIG. 4 comprises a trolley 310, which is illustrated in FIGS. 3A and 3B and which, in this exemplary embodiment, is designed by way of example as a roller trolley 312, or comprises a roller trolley 312 of said type. For example, it may be a standardized roller container which, in terms of basic dimension and preferably also of other dimensions, can be accommodated in a firefighting vehicle, an implement truck or, as illustrated in FIG. 3C, a roller container 314 for firefighting deployments. The trolley 310 comprises at least one support surface 316, for example in the form of a surface of a base plate 318, and a running gear 320. Furthermore, the trolley 310 may have at least one handle 324 and preferably at least one brake 326, for example a dead man's brake. As a possible exemplary embodiment of a trolley 310 of said type, reference may be made for example to universal roller containers from Gunzburger Steigtechnik GmbH, 89312 Gunzburg, Germany. Other trolleys, roller trolleys or roller containers may however also basically be used. In particular, use may also be made of entirely or partially closed roller containers.

[0129] As will be discussed in more detail further below, various elements of the mobile cleaning unit 410 are fixedly or detachably mounted on the trolley 310. In particular, as can be seen in FIG. 4, the mobile cleaning unit 110 comprises at least one cleaning appliance 110 and at least one pressurized-gas source 416. Further details will be described in more detail further below.

[0130] FIG. 1 illustrates an exemplary embodiment of the cleaning appliance 110, which is configured for cleaning one or more breathing apparatus 112 and which can be used in the mobile cleaning unit 410, for example as per FIG. 4. The cleaning appliance 110 is shown schematically in a sectional illustration in FIG. 1. The cleaning appliance 110 may be designed for example as a washer 114, wherein it is for example possible for industrial dishwashers to be correspondingly modified, for example under-counter washers from Meiko Maschinenbau GmbH & Co. KG, 77652, Offenburg. The cleaning appliance 110 comprises a cleaning chamber 116, for example a washing chamber 118. Said cleaning chamber 116 can for example be opened by means of a door 120, for example a pivoting door, a sliding door or a flap, and/or by means of some other opening appliance. Alternatively or in addition, the cleaning chamber 116 may also be designed as a cleaning chamber covered by means of a hood. In the exemplary embodiment illustrated in FIG. 1, the washer 114 is designed for example as a front-loader washer. Other embodiments are however also possible.

[0131] The cleaning appliance 110 has at least one fluid device 122 for applying one or more cleaning fluids to the breathing apparatus 112 accommodated in the cleaning chamber 116. For example, the fluid device 122 may comprise one or more nozzles 124 which may be arranged for example above and/or below the breathing apparatus 112 and/or at other locations within the cleaning chamber 116, for example on one or more side walls. For example, the fluid device 122 may, as in the illustrated exemplary embodiment as per FIG. 1, comprise a washing nozzle system 126, also referred to as wash nozzle system, for example with one or more nozzle arms which are accommodated below and/or above the breathing apparatus 112 and which are preferably mounted in a rotatable and/or pivotable manner and which have multiple nozzles 124. Alternatively or in addition, the fluid device 122 may also comprise a rinsing nozzle system 128, for example with one or more rinsing nozzle arms, which are preferably in turn mounted so as to be rotatable and/or pivotable and which may for example in turn be arranged above and/or below the breathing apparatus 112. Other arrangements and/or configurations are however basically also possible.

[0132] The fluid device 122 may furthermore comprise one or more further elements such as for example one or more pipelines, one or more pumps and/or one or more tanks. For example, in the exemplary embodiment illustrated, at least one washing line system 130 is thus provided for charging the washing nozzle system 126 with cleaning fluid 132, for example cleaner solution, from one or more washing tanks 134. For example, a washing tank 134 may be provided in the base region of the cleaning chamber 116, and/or connected in some other way to the cleaning chamber 116, such that cleaning fluid 132, after being applied to the breathing apparatus 112, can flow and/or drip back into the washing tank 134. For the charging of the washing nozzle system 126 with the cleaning fluid 132 from the washing tank 134, the fluid device 122 may furthermore have one or more circulating pumps 136. Furthermore, one or more heating elements 138 may be provided for warming the cleaning fluid 132 of the washing tank 134 and/or of other tanks, for example in the form of a washing tank heater within the washing tank 134. To monitor the heating of the cleaning fluid 132, one or more temperature sensors 140 may be provided, for example within the washing tank 134. Furthermore, one or more level sensors 142 may be provided, for example one level sensor 142 as a level sensor of the washing tank 134.

[0133] The washing tank 134 may for example be capable of being emptied via a discharge line 144 and optionally via a discharge pump 146 into a drain 148. The drain 148 may for example be connected to a waste water tank 412 of the mobile cleaning unit 410, which waste water tank is illustrated for example in FIG. 4 and is accommodated for example on the trolley 310. Alternatively or in addition, discharging into an on-site drain is also possible. Both possibilities may also be used in combination, including the option of switching between the two possibilities, for example if a waste water tank has reached its capacity limit. Furthermore, the mobile cleaning unit 410 may, as stated above, have a waste water lifting system (not illustrated here), for example for compensating differences in waste water level. In this regard, reference may for example be made to lifting systems from SFA Sanibroy GmbH, 63128 Dietzenbach, Germany.

[0134] It is optionally also possible for one or more feeds (not illustrated in FIG. 1) to the washing tank 134 to be provided in order to fill the latter with cleaning fluid 132. Said feeds may optionally be connected to an on-site supply and/or connected to a fresh water tank 414, which is shown for example in FIG. 4. Alternatively or in addition, filling may however also be realized via the rinsing nozzle system 128 that will be described in more detail below, for example via a fresh water feed 171. The fresh water feed 171 may for example be connected to a fresh water tank 414 of the mobile cleaning unit 410, optionally via the reverse osmosis device 170 that will be described in more detail further below.

[0135] Furthermore, a dosing system 150 may be provided, for example at least one dosing system for introducing one or more additives, for example a cleaner concentrate, a rinsing aid, a disinfection agent or combinations of these and/or other additives, into the cleaning fluid 132 of the washing tank 134. Storage vessels for the dosing system 150 may for example likewise be accommodated on the trolley 310.

[0136] The cleaning fluid 132 may in particular be applied to the breathing apparatus 112 in a circulation operating mode by virtue of the cleaning fluid 132 from the washing tank 134 being sprayed onto the breathing apparatus 112 by means of the wash nozzle system or washing nozzle system 126, before then running off or dripping off back into the washing tank 134 in order to be reused from there. It is optionally possible for one or more filters, for example coarse filters and/or fine filters, to be provided in order to at least partially purify the cleaning fluid 132 of the washing tank 134.

[0137] The rinsing nozzle system 128 may be charged with a further cleaning fluid 154, for example a rinsing liquid, for example via at least one rinsing line system 152. Here, FIG. 1 shows an optional embodiment in which the cleaning appliance 110 is designed as a two-circuit system. Accordingly, the second cleaning fluid 154 is provided for example from a separate tank, which in the exemplary embodiment illustrated is designed as a rinsing tank 156, which is formed separately from the washing tank 134. For example, said rinsing tank 156 may be in the form of a boiler, and may for example comprise a rinsing tank heater 158. Alternatively or in addition to a rinsing tank heater 158, it is also possible for other types of heating elements, for example one or more flow heaters, to be provided for the second cleaning fluid 154. The same also applies to the first cleaning fluid 132 in the washing tank 134. It is in turn possible for one or more temperature sensors 160 and/or one or more level sensors 162 to be provided in the rinsing tank 156, and the rinsing tank 156 may be fed with cleaning fluid 154, for example fresh water, via one or more feeds 164. The at least one feed 164 may have one or more valves 166. For example, the feed 164 may be connected or connectable via the fresh water feed 171 to an on-site fresh water connector, or may optionally be connected directly or indirectly to the fresh water tank 414, as stated above. A combination of the stated possibilities, including the option of switching between the two options, may also be realized. Alternatively or in addition, it is possible for at least one reverse osmosis device 170 to be provided on-site, as a constituent part of the cleaning appliance 110 or as a constituent part of the mobile cleaning unit 410, by means of which at least one reverse osmosis device the rinsing tank 156 and/or one or more other tanks of the cleaning appliance 110 can be charged with a permeate, for example purified water. Furthermore, it is in turn possible for at least one dosing system 168 to be provided, by means of which one or more additives, for example one or more rinsing aid concentrates, can be admixed to the cleaning fluid 154 in the rinsing tank 156.

[0138] The charging of the rinsing nozzle system 128 may preferably be performed in a single operating mode, that is to say not in a circulation operating mode, such that the rinsing fluid from the rinsing tank 154 is applied to the breathing apparatus 112 only once. For the application, the fluid device 122 may for example comprise one or more pressure-increasing pumps 172.

[0139] The cleaning of the breathing apparatus 112 in the cleaning appliance 110 as per FIG. 1 may for example be performed by virtue of firstly one or more breathing apparatus 112 being introduced into the cleaning chamber 116 by means of a suitable holder 174, which will be discussed in more detail further below. Subsequently, the door 120 can be closed, and it is preferably possible for a cleaning program to be started which can be controlled for example by means of a controller 176, for example a central machine controller or a peripheral controller. Here, it is for example possible for firstly the washing tank 136 to be filled by means of the rinsing nozzle system 128 with cleaning fluid 132 and/or with a precursor of said cleaning fluid 132, for example fresh water, in particular demineralized fresh water. This may then be conditioned within the washing tank 134, for example by admixing of one or more additives via the nozzle system 150 and/or by warming by means of the heating element 138. Alternatively or in addition, the cleaning fluid 132 may also have remained in the washing tank 134 after a rinsing program of a preceding cleaning cycle in order to be utilized in a subsequent cleaning cycle as cleaning fluid 132 and/or as a constituent part thereof, because rinsing fluid generally has a relatively high degree of purity even after being applied to the breathing apparatus 112.

[0140] The breathing apparatus 112 may subsequently be cleaned, in particular washed, preferably in a circulation operating mode, in one or more washing program steps. Here, adherent contaminants can be removed from the breathing apparatus 112, and/or hygienization of the breathing apparatus 112 can be performed.

[0141] Following the at least one washing program step, it is preferably possible for one or more rinsing steps to be performed. For this purpose, the washing tank 134 may optionally be emptied via the discharge line 144 and the discharge pump 146. The rinsing tank 156 may already have been filled with the rinsing fluid 154, for example fresh water with or without additives, for example demineralized fresh water, during the at least one washing program step. It is subsequently possible for one or more additives to be admixed by means of the dosing system 150, and/or warming of the cleaning fluid 154 as rinsing fluid may be performed by means of the rinsing tank heater 158 and/or by means of a flow heater. The rinsing fluid 154 that has been preconditioned in this way can then, in the at least one rinsing step, be applied via the rinsing nozzle system 128 to the breathing apparatus 112, such that said breathing apparatus are rinsed. The at least one rinsing step may optionally in turn be followed by at least one drying step, which may be of passive form, by means of a simple waiting time, or which may also be actively assisted, for example by means of at least one drying fan and/or some other type of drying appliance of the cleaning appliance 110, for example an infrared radiator system and/or a microwave radiation system. Various embodiments are conceivable. Following the optional drying step, the door 120, which has optionally preferably been locked up until this point, can be automatically released and/or opened. The entire program sequence may for example be controlled by means of the controller 176, wherein it is also possible for multiple program sequences to be selectable.

[0142] It is pointed out that the exemplary embodiment of the cleaning appliance 110 illustrated in FIG. 1 represents only one of several different exemplary embodiments. For example, it is possible for individual or several or even all of the elements described above to also be implemented in a different scope. Alternatively or in addition to the rigid, positionally fixed embodiment as per FIG. 1, the washing chamber 118 may also be designed to be pivotable and/or rotatable. It is furthermore also possible for the illustrated fluid circuit to be considerably modified.

[0143] As illustrated above, the at least one breathing apparatus 112 is held within the cleaning appliance 110 preferably by means of at least one holder 174. Such a holder 174 is shown by way of example in an enlarged sectional illustration in FIG. 2. The holder 174 may be produced for example from plastic and/or metal, and may for example be designed as a basket, as shown in FIG. 2. The holder 174 may comprise one or more support surfaces 178 and/or one or more holding elements 180, for example one or more baskets 182 and/or one or more connecting elements 184 for a mechanical connection to the breathing apparatus 112 and/or for the fixing thereof. Accordingly, the holder 174 may for example be designed to orient and/or to fix one or more components of the breathing apparatus 112 relative to one or more of the nozzles 124. For example, the breathing apparatus 112 may for example comprise at least one respiratory mask 186, wherein the orientation by means of the support surface 178 may for example be performed such that a visor 188 always points toward the upper nozzle system, whereas the inner side of the respiratory mask 186 points downward, such that cleaning fluid 132, 154 entering via the lower nozzles can run off again after being applied, without residues remaining within the respiratory mask 186. The basket 182 may for example be configured to accommodate accessories 190, which may likewise be constituent parts of the breathing apparatus 112, for example in order to maintain an assignment to other components of the breathing apparatus 112 during the cleaning process. In this way, it is for example possible to ensure that different types of breathing apparatus 112 can be cleaned without incompatible accessory parts being mixed up. Furthermore, the breathing apparatus 112 may for example comprise one or more breathing regulators 192 and/or one or more stages of such breathing regulators 192. Breathing regulators 192 of said type generally comprise, in their interior, one or more valves 194, for example diaphragm and/or toggle valves, by means of which one or more gas-conducting elements 196 are separated from an exterior space. For example, gas-conducting elements 196 may be provided in the interior of one or more gas lines 198 of the breathing regulator 192, wherein the inner walls of the gas line 198 generally must not come into contact with cleaning fluid 132, 154. The gas line 198 may for example end in one or more connectors 200, for example in one or more quick-action couplings.

[0144] In order to prevent the at least one gas-conducting element 196 of the breathing apparatus 112, for example the gas line 198 of the breathing regulator 192, from coming into contact with cleaning fluid 132, 154, provision is made for said gas-conducting element 196 to be charged with pressurized gas, for example during one or more program steps in which the cleaning fluid 132, 154 is applied to the breathing apparatus 112. For this purpose, the cleaning appliance 110 in this exemplary embodiment, or also in other exemplary embodiments, has at least one pressure-applying appliance 202. Said pressure-applying appliance 202 is configured to charge the at least one gas-conducting element 196 with pressurized gas. For this purpose, the pressure-applying appliance 202 has at least one pressure connector 204, which is connectable to the gas-conducting element 196 such that such charging with gas can be performed. In the exemplary embodiment illustrated, said pressure connector 204 is formed for example as a constituent part of the holder 174. Alternatively or in addition, however, the pressure connector 204 may also be provided at other locations in the cleaning appliance 110, preferably in the interior of the cleaning chamber 116. In the exemplary embodiment illustrated, the pressure connector 204 may for example be designed as a connector 206 for the breathing regulator 192. In this exemplary embodiment or also in other exemplary embodiments, the pressure connector 204 may in this case be generally designed such that it can be connected to several types of gas-conducting elements 196, for example to different types and/or different forms of gas-conducting elements 196. For example, the pressure connector 204 may comprise a multiplicity of adapters 205, and/or the cleaning appliance 110 may be supplied with an adapter set with multiple adapters 205 of different pressure connectors 204, such that there is a high level of flexibility with regard to the type of the gas-conducting elements 196. For example, the connector 206 may comprise, for the breathing regulator 192, a quick-action coupling which corresponds to the connector 200 of the gas line 198 and which is preferably connectable in pressure-tight fashion thereto. In this or also in other cases, the pressure connector 204 may thus also comprise at least one connecting element 208 and/or be designed as a connecting element 208 for producing a mechanical connection to the breathing apparatus 112 and in particular to the gas-conducting element 196.

[0145] For the charging of the pressure connector 204 and of the gas-conducting element 196 with pressurized gas, for example pressurized air, the cleaning appliance 110 and/or the mobile cleaning unit 410 may, in the exemplary embodiment illustrated or also in other embodiments, comprise at least one internal and/or at least one external pressurized-gas source 416, as shown in FIG. 4. For example, a pressurized-gas source 416 may be arranged on the trolley 310. Said pressurized-gas source 416 may for example comprise at least one compressor and/or at least one pressurized-gas bottle. Alternatively or in addition, the cleaning appliance 110 may also, as illustrated in FIG. 1, be equipped, by way of at least one external pressure connector 210, for being connected by way of said external pressure connector 210 to at least one external pressurized-gas source, for example an external pressurized-gas bottle and/or an external pressurized-gas line, which may be provided for example on site or on an implement truck or other firefighting vehicles. The external pressure connector 210 and/or the internal pressurized-gas source 416 may for example be connected via at least one pressurized-gas line 212 to the pressure connector 204. If the pressure connector 204 has been connected to a holder 174, as illustrated in FIGS. 1 and 2, then the pressurized-gas line 212 can for example be detachably connected to the holder 174 and/or to the pressure connector 204 in order to optionally permit a reversible removal of the holder 174 from the cleaning appliance 110. For example, for this purpose, one or more couplings 214 may be provided, which may for example in turn be connected via one or more pressurized-gas lines 216 to the pressure connector 204. It is also possible for a distributor system to be provided within or outside the holder 174, for example in order to be able to charge a multiplicity of pressure connectors 204 with pressurized gas by means of one pressurized-gas line 212. It is in turn also possible for one or more adapters 205 to be provided, for example in order to permit an adaptation to a multiplicity of different types of gas-conducting elements 196 and/or breathing apparatus 112. The pressure-applying appliance 202 may be designed to be separable at one or more points, for example in order to make it possible for the holder 174 to be removed from the cleaning chamber 116 and, for example, populated. For this purpose, the coupling 214 may for example be designed to be releasable. Furthermore, in this exemplary embodiment or also in other exemplary embodiments of the cleaning appliance 110, the pressure-applying appliance 202 may optionally comprise one or more valves 218, for example controllable valves, for example (as illustrated in FIG. 1) in the pressurized-gas line 212 and/or in or upstream of the external pressure connector 210. Said valves 218 may for example be controlled by the controller 176. It is thus possible, for example in this way or also in some other way, for the application of pressure to the at least one gas-conducting element 196 by means of the pressure-applying appliance 202 to be performed in controlled fashion in this exemplary embodiment or also in other exemplary embodiments of the invention, for example by virtue of the application of pressure being performed in targeted fashion prior to the commencement of an application of cleaning fluid 132, 154 to the breathing apparatus 112. Alternatively or in addition, the application of pressure may also be performed only in one or more program steps, for example only in one or more program steps during an application of cleaning fluid 132, 154 to the breathing apparatus 112. Optionally, the charging with pressurized gas, for example compressed air, may, by contrast, be deactivated and/or performed in some other form, for example with changed pressure, during other program steps. In this way, the application of pressure can for example be adapted to the various program steps.

[0146] The mobile cleaning unit 410 shown in FIG. 4 may comprise further elements aside from the elements mentioned above. In particular, the mobile cleaning unit may have at least one pressurized-gas pistol 418 connected to the pressurized-gas source 416. Furthermore, it is for example possible for a cabinet element 420 and/or a work surface 422 to be provided. Furthermore, on the trolley 310, there may for example be provided a washbasin 424, preferably with at least one hand shower 426, which may for example be designed as an extendable hand shower.

[0147] It is for example possible for cleaning agents 428 and/or other utensils to be stored in the cabinet element 420. Furthermore, it is possible for one or more of the abovementioned elements of the mobile cleaning unit 410 to be accommodated entirely or partially in the cabinet element 420.
