Description

Technical field

[0001] The invention relates to a cleaning device and a method for cleaning items. Furthermore, the invention relates to the use of the proposed cleaning device for cleaning personal protective equipment. The cleaning device and the method can be used, for example, in the field of cleaning personal protective equipment, and in particular respiratory masks and / or breathing apparatus. However, the invention can also be used in other areas, for example, in dishwashing technology, especially in the field of commercial dishwashing technology. Thus, the invention can be used, in particular, in commercial kitchens where heavily soiled items, such as containers or large cooking pots, need to be cleaned. Other areas of application are also conceivable. Technical background

[0002] A variety of cleaning devices, also known as cleaning equipment, are known from the prior art, which can clean and / or disinfect items. Examples of such cleaning devices can be found in DE 10 2004 056 052 A1 or DE 10 2007 025 263 A1.

[0003] It is the opinion of the Examining Division that JP 2002 065564 A describes a cleaning device according to the preamble of claim 1. KR 101 296 291 B1 describes a dishwasher having a rotating brush.

[0004] Without limiting further possible embodiments, the invention is described below with reference to items to be cleaned, which include personal protective equipment. Alternatively or additionally, items to be cleaned could also include, for example, items used for serving, preparing, or storing food, or other types of items.

[0005] Personal protective equipment (PPE) is used, for example, by rescue workers, armed forces, and security forces. An important component of PPE is typically respiratory protection equipment and its parts, such as respirators and / or demand valves. A wide variety of respiratory protection devices for different applications are currently available. For example, rescue workers like firefighters use respirators with filters to remove harmful substances from the inhaled air. In many cases, a demand valve is used, either as an alternative or in addition to a filter, which allows the user to be ventilated with a breathing gas, such as compressed air.Demand valves, also frequently referred to as breathing regulators, generally allow a user to breathe from a compressed gas cylinder or other compressed gas supply, thus enabling them to operate, for example, underwater or in other unbreathable or toxic atmospheres. To achieve this, the demand valve adjusts the pressure of the compressed gas, such as compressed air, from the gas supply to a pressure appropriate for the user's working environment.

[0006] Breathing apparatus or its components must generally be cleaned, sanitized, dried, inspected, and, if necessary, repaired and repackaged after each use. Cleaning is intended to remove all contamination resulting from use or storage, ensuring that the breathing apparatus is macroscopically clean and hygienically sound before being made available, for example, for the next steps in reprocessing. The same requirements generally apply to other components of breathing apparatus, such as attachments and accessories for breathing masks, like carrying frames, compressed gas cylinders, filters, or demand valves. Since breathing apparatus and its components are generally safety-relevant devices, several requirements must be observed when cleaning them.In addition to thorough cleaning and sanitization, it is often necessary to ensure that accessories remain assigned to their respective breathing masks for technical reasons. Furthermore, it is generally required that gas-carrying areas of certain components of breathing apparatus, such as gas-carrying areas of demand valves, must not come into contact with cleaning fluid, such as water and / or cleaning solution.

[0007] In many cases, respiratory equipment, such as breathing masks and their accessories, is either cleaned by hand or washed in modified washing machines using protective bags and / or adapters. For example, EP 0 935 687 B1 discloses a washing machine that has a tub with a drum. The drum's outer shell has a convex structure facing inwards, with holes arranged at the corners of the convexity's outer edges. Such washing machines allow for particularly gentle cleaning of equipment for rescue workers.

[0008] From EP 1 088 928 A1, a holding system for respiratory masks in a laundry treatment machine is known. The holding system has a carrying handle which is arranged to rotate in a drum of the laundry treatment machine and to which the respiratory masks can be attached.

[0009] Devices for treating protective suits are known from DE 200 03 743 U1 and DE 298 22 172 U1. These devices use clothes hangers that incorporate flexible air outlet nozzles. The clothes hangers are each attached to a swiveling device. Cleaning breathing apparatus using these devices is generally not possible or only possible with great difficulty.

[0010] From DE 10 2005 033 618 B3, a device for cleaning respiratory masks is known. The device comprises a lockable housing and at least one receptacle arranged in a carrier for at least one respiratory mask. Furthermore, a nozzle arrangement and a brush arrangement are provided, whereby brushing of the respiratory masks occurs through movement of the masks. However, the disclosed device does not allow for the individual assignment and cleaning of mask accessories. Furthermore, the cleaning of gas-carrying elements, such as demand valves, is not possible with the disclosed device. Also known from DE 200 03 744 U1 is a device for cleaning, disinfecting, and drying respiratory masks, which has a carrying frame with an associated nozzle system and individual treatment stations.This device is also fundamentally unsuitable for cleaning gas-carrying elements and accessories.

[0011] A cleaning device for compressed air breathing apparatus is known from DE 10 2007 009 936 A1. This device has a receiving chamber limited by a protective grille and rotating nozzle carriers. The nozzle carriers are located outside the protective grille. A disadvantage of the illustrated device, however, is that cleaning fluid can penetrate into gas-carrying areas.

[0012] The cleaning of sensitive components of respiratory devices, such as demand valves, is generally carried out manually. Manual cleaning can sometimes be supplemented by placing the components in ultrasonic cleaning devices. A method and a device for cleaning demand valves are known from DE 10 2007 012 768 B4. In this process, the items to be cleaned are placed on holders of a rotating element and immersed several times in a liquid bath containing cleaning fluid, disinfectant, and rinsing fluid. Demand valves are first pressurized with compressed air to create a seal between the valve and hose connection and then immersed in the liquid bath.However, a disadvantage of such immersion methods is that elaborate supports with corresponding actuators are required to ensure the removal of cleaning fluid from the various cavities after cleaning through appropriate movements.

[0013] DE 100 20 835 A1 describes a device for treating respiratory masks. It includes a receptacle for loading respiratory masks, to which the masks are connected via the breathing apparatus connection. The document further describes that a collection unit for collecting treatment agents and a pump for supplying these agents are provided in a compartment of the device.

[0014] US Patent 3,881,503 A discloses a device for washing and decontaminating anesthesia equipment. It features a nozzle system through which high-pressure jets of water can be sprayed onto the items being cleaned.

[0015] German patent DE 11 74 169 B describes a device for cleaning respiratory masks. A rotatably mounted tubular frame is provided in a housing, in which the masks to be cleaned are clamped onto holders. The respirators are moved by the rotating frame through a bath of cleaning fluid in a trough.

[0016] WO 2011 / 144518 A2 describes a cleaning device for cleaning breathing apparatus. The cleaning device comprises at least one cleaning chamber for accommodating at least one breathing apparatus and at least one fluid system for supplying the breathing apparatus with at least one cleaning fluid. The cleaning device further comprises at least one pressurization device with at least one pressure port. The pressure port is connectable to at least one gas-carrying element of the breathing apparatus. The pressurization device is configured to pressurize the gas-carrying element with pressurized gas.

[0017] US 2012 / 0284938 A1 describes a dishwasher that uses the abrasive forces of brushes to clean dishes. The dishes are held from above by a frame of parallel bars, allowing the upper oscillating brush to reach through the frame and clean the outside of the dishes. The dishes are held from below by the axis of the lower rotating brush, causing the brush to rotate and clean the inside of the dishes. The dishwasher also includes a rotating frame that holds the dishes at the beginning and throughout the wash cycle. This rotating frame consists of bars that support the dishes, a water slot to direct wash water into the wash chamber, and a movable lid that regulates the flow of wash fluid into the appropriate chambers.

[0018] DE 10 2017 202 055 A1 describes a cleaning device for cleaning items, comprising at least one cleaning chamber and at least one application device for applying at least one cleaning fluid to the items in the cleaning chamber. Furthermore, the cleaning device includes at least one control unit configured to operate the cleaning device in at least two modes. The control unit is also configured to record at least one usage variable. This usage variable characterizes the current use of the cleaning device. The control unit is further configured to assign at least one weight to this usage variable.The control system also includes at least one counting device, which is set up to accumulate weighted usage times of the cleaning device and to generate at least one usage information about a use of the cleaning device.

[0019] Despite the advantages achieved with the devices and methods described above, numerous technical challenges remain. One particular challenge is that personal protective equipment (PPE) often accumulates combustion residues, specifically soot, on its outer surfaces. These residues are often difficult to remove using conventional methods, especially since many PPE items, such as self-contained breathing apparatus (SCBA), can only be cleaned at relatively low temperatures. Surface effects play a significant role here, causing soot to adhere particularly strongly to various plastic surfaces due to electrostatic charging. Consequently, completely rinsing off the combustion residues, especially at low temperatures, is practically impossible. Object of the invention

[0020] It would therefore be desirable to provide a cleaning device and a method for cleaning items that largely avoid the disadvantages of known devices and methods of the aforementioned type. In particular, the cleaning device and method should be suitable for cleaning items with burnt residues, such as personal protective equipment or pots. General description of the invention

[0021] This problem is addressed by a cleaning device according to claim 1 and a method for cleaning items according to claim 9, as well as by a proposed use of the cleaning device for cleaning personal protective equipment, with the features of independent claim 1, according to claim 10. Advantageous embodiments, which can be implemented individually or in any combination, as is apparent to the person skilled in the art, are presented in the dependent claims.

[0022] In the following, the terms "have," "exhibit," "comprise," or "include," or any grammatical variations thereof, are used in a non-exclusive manner. Accordingly, these terms can refer both to situations in which, apart from the features introduced by these terms, no other features are present, and to situations in which one or more additional features are present. For example, the expression "A has B," "A exhibits B," "A comprises B," or "A includes B" can refer both to the situation in which, apart from B, no other element is present in A (i.e., a situation in which A consists solely of B) and to the situation in which, in addition to B, one or more other elements are present in A, such as element C, elements C and D, or even further elements.

[0023] Furthermore, it should be noted that the terms "at least one" and "one or more," as well as grammatical variations of these terms, when used in connection with one or more elements or features and intended to express that the element or feature may be present once or multiple times, are generally used only once, for example, when the feature or element is first introduced. Upon subsequent mention of the feature or element, the corresponding term "at least one" or "one or more" is generally no longer used, without restricting the possibility that the feature or element may be present once or multiple times.

[0024] Furthermore, the terms "preferably," "in particular," "for example," or similar terms are used in the following text in conjunction with optional features without limiting alternative embodiments. Features introduced by these terms are optional features, and it is not intended that these features limit the scope of protection of the claims, and in particular the independent claims. As the person skilled in the art will recognize, the invention can also be implemented using other embodiments. Similarly, features introduced by "in one embodiment of the invention" or by "in an exemplary embodiment of the invention" are understood as optional features without limiting alternative embodiments or the scope of protection of the independent claims.Furthermore, these introductory expressions are intended to leave all possibilities of combining the features introduced herein with other features, whether optional or non-optional features, unaffected.

[0025] The first aspect of this proposal is a cleaning device for cleaning items. As stated above, the items to be cleaned can include at least one piece of personal protective equipment, specifically at least one item comprising at least one breathing apparatus. Alternatively or additionally, as stated above, other types of items are also conceivable, such as one or more items used for serving, preparing, or storing food. In general, items to be cleaned can include those bearing combustion residues, particularly soot.

[0026] The term "cleaning device," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a device designed to remove adhering macroscopic or microscopic contaminants from items being cleaned, or at least to partially remove such contaminants. An additional disinfection effect can optionally be achieved. As will be explained in more detail below, the cleaning device can be designed in particular as a dishwasher, for example, a dishwasher for personal protective equipment and / or a dishwashing machine, for example, a container washer.The dishwasher can be designed as a single-chamber dishwasher, particularly as a commercial single-chamber dishwasher with a multi-circuit washing system, as a front-loading dishwasher, or as a hood-type dishwasher, particularly as a pass-through dishwasher. Dishwashers with water exchange, especially so-called single-circuit systems, can also be used. Alternatively or additionally to dishwashers, other types of cleaning equipment can also be used.

[0027] The cleaning device comprises at least one cleaning chamber for the stationary mounting of at least one cleaning basket containing the items to be cleaned. The term "cleaning chamber," as used here, is a broad term and should be understood in its usual and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a fully or partially enclosed chamber within which the cleaning process can be carried out completely or partially. The cleaning chamber can, in particular, have at least one housing that fully or partially encloses the cleaning chamber. A single cleaning chamber may be provided, or, in principle, several cleaning chambers may be provided, for example, sequentially.The cleaning chamber can, for example, have at least one opening for loading the items to be cleaned. This could be an opening with a flap located on the front and / or top of the cleaning chamber. Alternatively, hoods can be used to close the cleaning chamber, for example, in so-called hood-type dishwashers or pass-through dishwashers. Other designs are also possible.

[0028] The cleaning chamber is designed to accommodate at least one cleaning basket. For this purpose, the cleaning chamber may, for example, have at least one basket receptacle, such as at least one rail into which the cleaning basket can be inserted, and / or at least one holding device or transport device by means of which the basket can be transported into, out of, or through the cleaning chamber.

[0029] The cleaning device is designed, as described above, such that the cleaning basket is held in a fixed position during cleaning, particularly during the application of at least one cleaning fluid, as described in more detail below. This can mean, in particular, that the cleaning basket is held on or in at least one basket holder during cleaning and is not, for example, swiveled, rotated, lifted, immersed, or moved in any similar manner during cleaning. Thus, the cleaning basket can remain stationary, for example, during the application of the at least one cleaning fluid.The cleaning chamber can, for example, be designed as a single chamber in which at least one cleaning basket can be accommodated, for instance, in a basket holder. The basket holder is designed in such a way that the cleaning basket remains stationary during cleaning, particularly during exposure to the cleaning fluid, and is therefore not moved translationally or rotationally. Specifically, the bottom of the cleaning basket can remain in a horizontal position during cleaning. However, it remains possible for the cleaning basket to be removed manually or automatically from the cleaning chamber or the corresponding cleaning zone after exposure to the cleaning fluid, allowing for subsequent cleaning and / or other treatment.

[0030] The cleaning device further comprises at least one application device for applying at least one cleaning fluid to the item being cleaned. The term "application device," as used here, is a broad term and should be understood to have its usual and common meaning as understood by a person skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to any device by means of which the item being cleaned can be applied to the cleaning fluid, in particular to at least one cleaning fluid, within the cleaning chamber.

[0031] The term "exposure" can generally be understood as any contact between the item being cleaned and the cleaning fluid. This can be done, in particular, by direct exposure, for example, by spraying, dripping, irradiating, or a combination of these and / or other direct exposure methods, in which the pre-cleaning fluid directly impacts the item being cleaned, for example, the breathing apparatus and / or the breathing mask, preferably with a pulse greater than zero. Exposure can be carried out in a simple operation by applying the cleaning fluid to the item only once. Alternatively or additionally, cleaning can also be carried out in a recirculating operation by applying the cleaning fluid to the item multiple times. Such recirculating operations and cycles are known, for example, from conventional dishwashers or washing machines.A recirculation system can be implemented, for example, using at least one recirculation pump, which collects the cleaning fluid already applied to the items being cleaned and reuses it for further application. A combination of a simple operation and a recirculation system is also possible, for example, by performing at least one washing step with at least one washing fluid in a recirculation mode, followed by at least one rinsing step, also known as a clear rinsing step, in which the items are applied with at least one rinse fluid in a simple operation.

[0032] The application device can, in particular, comprise at least one nozzle system, for example, at least one nozzle arm, for example, at least one rotatably mounted nozzle arm. For example, at least one nozzle arm, for example, a rotatably mounted nozzle arm, can be arranged below the item to be cleaned in the cleaning chamber, and at least one nozzle arm, for example, a rotatably mounted nozzle arm, can be arranged above the item to be cleaned. Separate nozzle arms for washing fluid and rinsing fluid can be provided above and below the item to be cleaned, for example. Furthermore, the application device can comprise at least one pump and at least one piping system for supplying cleaning fluid to the nozzle system.This may include, for example, a nozzle system and a piping system for supplying cleaning fluid from at least one tank, such as at least one wash tank, as well as at least one pump, such as at least one wash pump. Furthermore, at least one nozzle system and at least one piping system for supplying cleaning fluid from at least one optional rinse tank may be provided, which is preferably separate from the wash tank and in which the rinse fluid can be treated separately from the wash tank, as well as at least one rinse pump. By providing at least one rinse tank separate from the wash tank, the cleaning device can be designed for commercial use, as heating time can be saved during a single wash step through separate treatment of the rinse fluid.For example, the rinse tank can be designed as a boiler and / or can have an instantaneous water heater.

[0033] The term "cleaning fluid," as used here, is a broad term and should be understood in its usual and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer to any fluid, and in particular any liquid, which, upon contact with the item being cleaned, can have a cleaning effect. In particular, the cleaning fluid can be aqueous, for example, water and / or water with one or more additives, such as one or more cleaning concentrates and / or rinse aids and / or disinfectants. The cleaning device can be configured to use a single cleaning fluid or a combination of several cleaning fluids.If multiple cleaning fluids are used, the items to be cleaned can be treated with the different cleaning fluids simultaneously or sequentially. For example, as described above, the items can remain stationary within the cleaning chamber and be treated with the different cleaning fluids one after the other. Alternatively, the items can be treated sequentially in different locations, such as different chambers, with different types of cleaning fluids. This could involve, for instance, the items first remaining stationary in a first cleaning chamber, being treated with at least one cleaning fluid, and then being moved to at least a second cleaning chamber, where they remain stationary and are treated with at least one second cleaning fluid.

[0034] Without limiting further possible configurations, the following refers to automated cleaning machines in which the items to be cleaned remain stationary in a single cleaning chamber during the cleaning process.

[0035] The cleaning device can, for example, be configured to carry out at least one cleaning program by means of the application device, for example, controlled by at least one control unit of the cleaning device, in which the item to be cleaned, for example, the at least one cleaning basket containing the item, is stationary in the cleaning chamber and is successively exposed to cleaning fluid in one or more cleaning steps of the cleaning program in different ways, for example, first in at least one washing step with the at least one washing fluid and in at least one rinsing step with the at least one rinse fluid. Furthermore, at least one drying step can be provided, which, for example, can be located in one of the cleaning chambers after the item to be cleaned has been stationary and exposed to the cleaning fluid.Accordingly, the cleaning device can be designed in particular as a programmed automatic cleaning system.

[0036] The term "tank," as used here, is a broad term and should be understood in its usual and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a completely or partially enclosed container designed to hold at least one cleaning fluid, especially at least one liquid. As explained above, the at least one tank may, for example, comprise at least one wash tank. This at least one wash tank may, for example, be located in the base of the cleaning chamber or be fluidically connected to the base of the cleaning chamber so that cleaning fluid can flow from the cleaning chamber into the wash tank. For example, the wash tank may be separated from the cleaning chamber by at least one sieve.In addition to the at least one wash tank, the at least one tank can also include one or more further tanks. For example, the at least one tank can have at least one rinse tank, which may be separate from the wash tank. In the at least one rinse tank, at least one rinse fluid, also known as a clear rinse fluid, can be prepared, for example, heated, while a further washing step takes place in the cleaning chamber. The rinse tank can, for example, include at least one boiler.

[0037] The cleaning device further comprises a plurality of movable cleaning elements. The movable cleaning elements are arranged to be movable relative to the cleaning basket and are designed to remain in the cleaning chamber during the exposure of the item to be cleaned to the cleaning fluid. Furthermore, the movable cleaning elements are designed to be set in motion by the cleaning fluid, in particular by a flow of the cleaning fluid, and are designed to exert a mechanical cleaning effect on the item to be cleaned during this exposure.

[0038] The term "cleaning element," as used here, is a broad term and should be understood in its usual and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer, in particular, to a device of any shape that is designed to act mechanically on items to be cleaned in order to achieve a mechanical cleaning effect. The device can, in particular, be made wholly or partially of one or more solids, i.e., one or more materials of a solid phase, which may preferably be flexible or deformable. Accordingly, the term "cleaning element," as used here, should be understood in this way. It, too, should be understood in its usual and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning.The term can, without limitation, refer in particular to a cleaning element as defined above, which is designed to be at least partially movable. This mobility can be such that the cleaning element can move freely within the cleaning chamber. This can be the case, for example, if the movable cleaning elements, or at least some of them, comprise a number of solid bodies, such as spheres or other three-dimensional objects, which are free to move within the cleaning chamber but cannot leave it. Alternatively or additionally, the movable cleaning elements can also be designed with only partial mobility.This partial mobility can be achieved, for example, by having the movable cleaning elements attached at least at one point, such as to at least one wall of the cleaning chamber and / or to the cleaning basket, and designed to be movable at least at one other point, so that at least the movable part can mechanically act on the items being cleaned in the cleaning basket. This can be accomplished, for example, by designing the cleaning elements as belts, loops, or threads, which are attached at one end or at one point, such as to at least one wall of the cleaning chamber, particularly in the area of ​​the ceiling of the cleaning chamber, and / or to the cleaning basket, and which have at least one freely movable part or section, such as a freely movable end, that can mechanically act on the items being cleaned.For example, the movable cleaning elements can be dimensioned in such a way that they extend from the fixed part at least to the cleaning basket, in particular to the bottom of the cleaning basket or just above it, so that these movable cleaning elements can mechanically act upon the item being cleaned. The mobility can therefore refer in particular to the mobility of at least one free part of the cleaning elements, for example, at least one free end that can move freely relative to the cleaning basket.

[0039] As described above, the movable cleaning elements are designed to remain in the cleaning chamber while the items to be cleaned are exposed to the cleaning fluid. This can be achieved, in particular, by attaching at least one part of the movable cleaning elements to the cleaning chamber and / or the cleaning basket. Alternatively, as described above, the movable cleaning elements can also move freely within the cleaning chamber. In this case, at least one sieve and / or at least one grid can be used, for example, to ensure that these cleaning elements do not leave the cleaning chamber. Alternatively, the cleaning elements can also be dimensioned in such a way that they cannot leave the cleaning chamber, for example, by being larger than the cross-sectional area of ​​a drain.Alternatively or additionally, the cleaning elements can be contained in at least one retention element within the cleaning chamber, for example at least one basket, so that, for example, the cleaning basket itself can also be designed as a closed basket with the cleaning elements contained therein and freely movable within it.

[0040] The movable cleaning elements are, as described above, designed to be set in motion by the cleaning fluid, in particular a flow of the cleaning fluid. The movable cleaning elements can be arranged, in particular, in the area of ​​droplets or jets of cleaning fluid emerging from the application device, especially one or more nozzles of the application device, and can be designed with regard to their mass and / or density as well as their mobility such that these droplets or jets from the application device set the movable cleaning elements in motion, either wholly or partially.For example, the application device can be configured such that, for instance, a pump output and / or an orientation of the nozzle elements of the application device are set for the appropriate impingement of the movable cleaning elements with a pulse from drops and / or jets of the cleaning fluid. If the movable cleaning elements are, for example, designed wholly or partially as belts or threads which, for instance, extend vertically in a resting state due to their gravity, the application device can, for example, be configured such that the drops and / or jets of the cleaning fluid strike the movable cleaning elements with a direction of movement perpendicular to the vertical, thereby imparting a pulse with at least one pulse component in the horizontal direction and setting them in motion.

[0041] As described above, the movable cleaning elements are designed to exert a mechanical cleaning effect on the item being cleaned while it is exposed to the cleaning fluid. This can be achieved, in particular, by allowing at least a portion of the movable cleaning elements, which is imparted with an impulse by the cleaning fluid during exposure, to act upon the item in the cleaning basket. As described above, this movable portion can be, in particular, a movable end of the movable cleaning elements, for example, a free end. Alternatively or additionally, as described above, the movable cleaning elements can also be movable as a whole and act upon the item as a whole.In general, mechanical action can cause abrasion, in particular the removal of combustion residues such as soot, from at least one surface of the item being cleaned. Other types of contaminants, such as grease and / or adhering starch, can also be removed from the at least one surface by mechanical action.

[0042] The movable cleaning elements can, as described above, be made at least partially from at least one flexible material. A flexible material in this context can be understood to be, in particular, a deformable material, especially one that can reversibly deform under the influence of its own weight. This flexible material can exhibit elastic or plastic properties. Combinations of several materials are also possible.

[0043] In particular, the movable cleaning elements may be made at least partially from at least one textile material. Textile materials may, in particular, comprise at least one material selected from the group consisting of: a woven fabric; a knitted fabric; a braided fabric; a sewn knit fabric; a nonwoven fabric; a felt. Natural materials or synthetic materials may be used. In particular, the textile material may comprise at least one material selected from the group consisting of: a natural fiber; cotton; a textile synthetic material, in particular a textile synthetic material selected from the group consisting of: polyester; polyamide, in particular Nylon®. Other materials that can be processed into textiles are also generally suitable.

[0044] Alternatively or additionally to the use of at least one textile material, the movable cleaning elements can be made at least partially from at least one plastic material. In particular, this textile-like plastic material can be at least one elastomer. Alternatively or additionally, other plastic materials can also be used, especially thermoplastic plastic materials. The at least one plastic material can, for example, be used as strip material. Alternatively or additionally, the at least one plastic material can also be used, for example, in the form of threads, which can then be processed into a textile-like plastic material, which in turn can be used, for example, as tapes.Alternatively or additionally, the at least one plastic material can also include, for example, at least one foam material, such as a foam material designed as strips. In particular, the at least one plastic material can be selected from the group consisting of: ethylene propylene diene monomer rubber; polyurethane.

[0045] As explained above, the movable cleaning elements, or at least some of them, can have an elongated, flexible shape. In particular, they can take the form of bands and / or threads. Other elongated configurations are also conceivable.

[0046] The movable cleaning elements, or at least some of them, can have at least one shape selected from the group consisting of: a spherical shape; a thread shape; a strip shape. A spherical shape can be chosen, for example, if the cleaning elements are freely movable within the cleaning chamber. For instance, spheres made of a textile material and / or spheres made of a lightweight material such as a lightweight plastic, or even hollow spheres covered with a textile surface, can be used. In general, the movable cleaning elements can have at least one textile surface capable of exerting an abrasive effect on the soiled surface.

[0047] As further explained above, in addition to cleaning elements that are completely free to move within the cleaning chamber or within a part of the cleaning chamber, movable cleaning elements are provided which are fixed within the cleaning chamber. In particular, the movable cleaning elements are at least partially fixed within the cleaning chamber. For example, the movable cleaning elements can be directly or indirectly connected to at least one part of the ceiling of the cleaning chamber and / or to another part of a wall of the cleaning chamber, and / or be attached to a part that is connected to a wall of the cleaning chamber, for example, the ceiling of the cleaning chamber.For example, tapes and / or threads can hang directly from the ceiling of the cleaning chamber or from a part, such as a plate, that is connected to the ceiling or another part of the cleaning chamber. In this case, the tapes and / or threads can, for example, extend vertically through the cleaning chamber.

[0048] As explained above, each movable cleaning element has at least one freely movable part, in particular a free end, which is designed to act mechanically on the item being cleaned. The freely movable part can rest on the item being cleaned, particularly due to its own weight.

[0049] The cleaning device further comprises at least one release device, which is configured to mechanically separate the freely moving parts of the movable cleaning elements from the item being cleaned. The term "release device," as used here, is a broad term and should be understood to have its ordinary and common meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to any device, especially a mechanical device, which is configured to act mechanically on the movable cleaning elements, or at least a part thereof, in such a way as to separate them from the item being cleaned.This can be particularly advantageous during loading or unloading of the cleaning device to prevent, for example, the insertion of a cleaning basket into the cleaning chamber and / or the removal of the cleaning basket from the cleaning chamber from being disrupted by the moving cleaning elements. Alternatively or additionally, the release device can also cause separation during one or more program steps of a cleaning program, for example, during a rinse cycle and / or a drying cycle. In this way, for example, it can be prevented that cleaning fluid adhering to the moving cleaning elements from a previous program step interferes with the currently running program step, such as the drying cycle.

[0050] In particular, the release device may have at least one slide. This slide may be configured to push the freely moving parts of the movable cleaning elements away from the item being cleaned. Alternatively or in addition to at least one slide, other release devices may also be used, for example, at least one swivel arm or similar mechanical devices.

[0051] As explained above, a single release device may be provided. However, multiple release devices or multiple parts of the release device are also possible. In particular, the release device may have at least two sub-devices, wherein the sub-devices are configured to move the freely movable parts of the movable cleaning elements away from the item being cleaned in at least two different directions. For example, the at least two parts may comprise two or more sliders that can move in different directions. Thus, for example, a bundle of the movable cleaning elements, such as a bundle of belts or threads, may be pushed by the release device in a single direction or may be divided into sub-bundles that can be pushed in different directions.The latter can be done, for example, analogously to opening a curtain consisting of several parts, whereby the curtain in this case may consist of ribbons and / or threads.

[0052] The release device can be configured, in particular, to automatically and mechanically separate the freely moving parts of the movable cleaning elements from the item being cleaned when the cleaning chamber is opened. When the cleaning chamber is closed, the release device can be configured to reverse this separation and, in particular, to allow renewed contact between the freely moving parts of the movable cleaning elements and the item being cleaned.

[0053] As explained above, the movable cleaning elements can be attached, in particular directly or indirectly, to at least one part of the cleaning device, especially to at least one part of the cleaning chamber. Specifically, the movable cleaning elements can be attached, at least partially, to at least one movable element of the cleaning device. The cleaning device can be configured to set the movable cleaning elements in motion by means of the movable element, in addition to the movement caused by the cleaning fluid. For example, the movable element can have at least one oscillating plate on the ceiling of the cleaning chamber, such as a vibrating plate or a plate moved by at least one eccentric or other oscillating actuator.In this way, for example, the freely moving parts, especially the free ends, of the movable cleaning elements can be moved back and forth on the item being cleaned to create additional abrasion.

[0054] Furthermore, the cleaning device according to the present invention, which can be specifically configured for personal protective equipment, can also implement the protection of gas-carrying elements described above during exposure to cleaning fluid, in order to ensure that the cleaning fluid cannot penetrate the interior of the gas-carrying elements. In particular, the cleaning device can have at least one pressurization device with at least one pressure connection, wherein the pressure connection can be connected to at least one gas-carrying element of the item being cleaned, in particular the breathing apparatus. The pressurization device can be configured to pressurize the gas-carrying element with pressurized gas during the application of the cleaning fluid to the item being cleaned.

[0055] The term "pressurization device," as used here, is a broad term and should be understood in its ordinary and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a device designed to supply a fluid, especially a gas, at a pressure above normal atmospheric pressure, for example, a pressure of at least 1.5 bar, preferably a pressure of at least 2 bar. The term "pressure connection," as used here, is a broad term and should be understood in its ordinary and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning.The term can, without limitation, refer in particular to any connection of the pressurization device through which the fluid, especially the gas, can be supplied to the pressurization device. In particular, this pressure connection can be located inside the cleaning chamber and / or be accessible from inside the cleaning chamber. The provision of multiple pressure connections is also conceivable.

[0056] The pressure connection can be connected to at least one gas-carrying element of the item being cleaned, in particular the personal protective equipment and especially the breathing apparatus, in the cleaning chamber, preferably to several gas-carrying elements of several pieces of the item being cleaned. The term "gas-carrying element," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to an element which, during use of the item being cleaned, is exposed to at least one gas, in particular to an element which, during use of the personal protective equipment, for example the breathing apparatus, by a human or animal user, is exposed to a breathing gas or which can otherwise come into contact with the breathing gas.In particular, this can be a demand valve and / or a breathing tube with at least one valve. Specifically, the gas-carrying element can be an element that includes at least one tube and / or at least one other type of gas-carrying device with an interior space and / or at least one valve, which generally must not be exposed to cleaning fluid. For example, the gas-carrying element can be a section of the breathing apparatus that is pressurized during operation at a pressure above normal pressure, such as a gas-carrying section of a breathing apparatus operating at a pressure above normal pressure, for example, above 1.5 bar, and in particular above 2 bar. Specifically, it can be a breathing gas-carrying section of a demand valve, whereby the demand valve can be either a single-stage or a multi-stage device.The gas-carrying element can be, for example, part of a first stage and / or a second stage and / or, if applicable, further stages of the regulator, or even a complete regulator. For instance, the gas-carrying element could be the area between a hose connection and a valve of a regulator, or it could encompass such an area.

[0057] A connection between the pressure port and the gas-carrying element can generally be understood as a fluidic connection, in particular a gas connection, such that the pressurized fluid of the pressurization device can be transferred into the gas-carrying element, in particular into an interior of the gas-carrying element, preferably without any fluid loss and / or pressure loss occurring at this connection. Furthermore, the connection between the pressure port and the gas-carrying element can optionally comprise at least one mechanical connection, in particular a positive-locking and / or force-locking connection, so that the gas-carrying element can be firmly connected to the pressure port.For example, this can be a screw connection, a clamp connection, or a clamping connection, for which the pressure connection and / or the gas-carrying element can each have at least one mechanical connecting element. In particular, this can be a push-fit connection in the form of a quick-release coupling and / or a threaded connection, for example, a coupling piece for a breathing connection of a regulator. A quick-release coupling is generally understood to be a gas-tight and / or liquid-tight push-fit connection between two fluid-carrying components, which can be mechanically secured by a mechanical fixing that can be easily and quickly made and released, in particular without the use of a screw closure, for example, by at least one clamping hook and / or a bayonet fitting and / or a screw closure, such as a union nut.The connection can be made without tools. Specifically, the pressure connection can include multiple fixed or interchangeable adapters for connecting to different types of gas-carrying elements. These adapters allow for the direct or indirect connection of multiple gas-carrying elements to the pressure connection, such as different types and / or models of gas-carrying elements from different manufacturers or brands. For example, an adapter set can be provided with multiple different couplings (e.g., quick-release couplings) and / or threads for connecting different gas-carrying elements. These could include, for example, different quick-release coupling systems and / or standard threads.Alternatively or additionally, the at least one pressure connection can also be designed as a fixed pressure connection for a specific type of connecting element or for a specific type of gas-carrying element. It is particularly advantageous if the pressure connection and / or the coupling system are designed in such a way that, on the one hand, no gas can escape when no mating part is connected, and that, in this case, no other medium, for example cleaning fluid, can enter the gas-carrying element.

[0058] The pressurization device can, as described above, be configured to pressurize the gas-carrying element with pressurized gas. A pressurized gas can generally be understood to be any gas that has a pressure above normal atmospheric pressure, i.e., a pressure above 1 bar. In particular, it can be a pressure above 1.5 bar, more preferably above 2 bar, and most preferably above 3 bar. The pressurization device can be configured such that the pressurization with the pressurized gas is carried out in such a way that all cleaning fluid is kept out of the interior of the gas-carrying element pressurized with the pressurized gas. The pressurized gas can be, for example, compressed air or another gaseous medium at an overpressure, such as nitrogen, carbon dioxide, or the like. In particular, an inert gas can be used as the pressurized gas.The cleaning device can be designed such that pressurization via the pressurization device occurs during at least one cleaning process, for example, during at least one program step of a single-step or multi-step cleaning program. In particular, the pressurization with the compressed gas can occur simultaneously with the pressurization of the gas-carrying element with the cleaning fluid. Accordingly, the pressure connection can be located, in particular, within the cleaning chamber, so that simultaneous pressurization with compressed gas and cleaning fluid is possible.

[0059] The pressurization device may in particular comprise at least one element selected from the group consisting of: at least one external pressure connection for connection to an external compressed gas source outside the cleaning device, in particular a customer-provided compressed gas line and / or a compressed gas cylinder; a compressed gas source integrated into the cleaning device, in particular an integrated compressed gas cylinder and / or an integrated compressor.

[0060] As described above, the pressure connection can, in particular, comprise at least one positive-locking and / or force-locking connecting element. This connecting element can be configured to establish a mechanical connection with the gas-carrying element in addition to the gas-tight connection. In particular, this at least one connecting element can have at least one quick-release coupling and / or at least one thread. Generally, the pressure connection can, in particular, be fully or partially integrated into the cleaning basket. The cleaning basket can, in general, have at least one detachable pressurized gas connection to the cleaning device. The pressurization device can, in particular, have at least one valve, in particular at least one valve that can be controlled by the control system of the cleaning device.

[0061] As described above, the cleaning chamber is designed to accommodate at least one cleaning basket containing items to be cleaned. The cleaning basket can be reversibly inserted into the cleaning chamber. The cleaning basket itself can be part of the cleaning device or considered separately. For example, the cleaning device can be designed as a set together with one or more cleaning baskets. In particular, the at least one cleaning basket can be designed as part of the cleaning device, but it can be reversibly inserted into the cleaning chamber independently of the rest of the cleaning device.

[0062] The term "cleaning basket," as used here, also referred to as "dishwashing basket," is a broad term to which its usual and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to a specific or adapted meaning. Without restriction, the term can refer in particular to a portable device in which items to be cleaned can be placed, inserted into a cleaning appliance, such as a dishwasher, and subsequently removed from the cleaning appliance in a clean state. Alternatively, the cleaning basket can also be permanently installed in a cleaning appliance.For example, the cleaning basket can be attached to a rail system of the cleaning device and inserted into a cleaning chamber of the device via this system. After cleaning, it can be pulled out of the cleaning chamber again. Cleaning baskets can also serve for the temporary storage of items to be cleaned. The cleaning basket can, in particular, have numerous openings to allow liquid to drain downwards. Generally, the cleaning basket can, for example, have at least one frame. The cleaning basket can, in particular, have a substantially cuboid shape with a base that can, for example, have a square or generally rectangular footprint, and which provides a support surface for placing the cleaning basket on a flat work surface.Optionally, one or more basket walls can extend upwards from the bottom of the basket, for example with a raised rim and optionally other elements such as handles.

[0063] In particular, the item to be cleaned, or at least a part of it, can be fixed in the cleaning basket during contact with the cleaning fluid. Accordingly, the cleaning basket can have at least one fixing element for securing the item within the basket. This at least one fixing element can, for example, include the at least one pressure connection as described above, by means of which, for example, at least one gas-carrying element of the item to be cleaned can be fixed to the cleaning basket. However, other types of fixing elements are also possible. For example, the at least one fixing element can include at least one element by means of which a force-fit and / or form-fit fixing of the item to the cleaning basket is possible, such as at least one clamp, at least one thread, at least one fixing band, at least one hook, or other fixing elements.Furthermore, at least one enclosed small parts basket may be provided on or in the cleaning basket, in which small parts can be collected and cleaned, and one or more other parts of the items to be cleaned can be accommodated outside the small parts basket in the cleaning basket, in particular being fixable.

[0064] As described above, the cleaning basket can be part of the cleaning device or part of a set or kit that includes the cleaning device and at least one cleaning basket. The at least one movable cleaning element can, as described above, be wholly or partially attached to the cleaning device, for example, within a chamber of the cleaning device. Alternatively or additionally, the at least one movable cleaning element can also be wholly or partially attached to the at least one cleaning basket.

[0065] Accordingly, in a further aspect, a cleaning basket for use in a cleaning device according to the invention, for example according to one or more of the embodiments described above and / or according to one or more of the embodiments described in more detail below, is disclosed.

[0066] The cleaning basket has at least one basket frame for holding the items to be cleaned. The term "basket frame," as used here, is a broad term and should be understood in its usual and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a basic mechanical structure of the cleaning basket, which may include a basket base, as well as one or more basket walls, which may extend from the basket base. The basket frame may be made entirely or partially of at least one material selected from the group consisting of plastic and metal. The basket frame may, for example, be designed entirely or partially as a wire frame, such as a wire mesh.Alternatively or additionally, the basket frame can also be made entirely or partially of plastic, for example, as a plastic frame with multiple openings, such as a plastic grid. The basket frame can, for example, have one or more openings to allow cleaning fluid to flow out of its interior. The basket frame can, for example, have a cuboid base structure, either entirely or partially, such as with a rectangular support surface.

[0067] The disclosed cleaning basket further comprises a plurality of movable cleaning elements. The movable cleaning elements are arranged to be movable relative to the cleaning basket and are designed to be set in motion by the cleaning fluid, in particular a flow of the cleaning fluid, and to exert a mechanical cleaning effect on the item to be cleaned during contact with the at least one cleaning fluid.

[0068] The cleaning basket, at least one of the baskets, can be designed as an open cleaning basket, for example, one that opens at the top. This allows items to be placed or laid freely into the basket from above and secured there.

[0069] The basket frame can, in particular, as described above, have at least one basket base, especially an open or closed basket base. Furthermore, the basket frame can have at least one cleaning element carrier arranged above the basket base, wherein the items to be cleaned can be held between the basket base and the cleaning element carrier. The movable cleaning elements can each be attached at one end to the cleaning element carrier and furthermore have at least one freely movable part, in particular a free end, wherein the freely movable part, when the cleaning basket is placed in the cleaning chamber, can extend towards the items to be cleaned by its own weight. The term "cleaning element carrier," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed.The term is not limited to a specific or adapted meaning. Without restriction, the term can refer to any component of the basket frame designed to hold the movable cleaning elements. Specifically, the cleaning element support can include at least one arm, which may be rigid or extendable, extending at least partially above the basket floor so that the item to be cleaned can be held between the arm and the basket floor. From this arm, the movable cleaning elements can extend towards the item being cleaned. For example, the movable cleaning elements can be in the form of straps or threads hanging from the arm down to the item being cleaned. There, these movable cleaning elements can be set in motion by the cleaning fluid.For loading and / or unloading the cleaning basket, the arm can be folded down, for example. Generally, the cleaning element carrier can be, for example, a fold-out or extendable cleaning element carrier, or it can include at least one fold-out or extendable cleaning element carrier.

[0070] As described above, the cleaning device can be configured such that, during the application of the cleaning fluid to the item being cleaned, at least one gas-carrying element of the item is pressurized. Accordingly, the cleaning basket can be designed to have at least one pressure connection. This pressure connection can be connected to at least one gas-carrying element of the item being cleaned, in particular the breathing apparatus. Through this pressure connection, the at least one gas-carrying element of the item being cleaned can be pressurized with pressurized gas during the application of the cleaning fluid. For further possible configurations, particularly regarding the pressure connection and / or the pressurized gas, please refer to the above description of the cleaning device.

[0071] In another aspect, a method for cleaning items is proposed. This method comprises the steps listed below. These steps can be carried out in the order shown. Furthermore, one or more of the process steps can be performed simultaneously, overlapping in time, or repeatedly. The method may also include additional, unmentioned steps.

[0072] The process includes the following steps: i. Providing at least one cleaning device according to the invention, in particular according to one or more of the embodiments described above and / or according to one or more of the embodiments described in more detail below; ii. Receiving the item to be cleaned into at least one cleaning basket; iii. Inserting the cleaning basket into the at least one cleaning chamber of the cleaning device; and iv. Applying the cleaning fluid to the item to be cleaned in the cleaning chamber.

[0073] During the application process in step iv, the movable cleaning elements mechanically act on the item being cleaned. The cleaning fluid sets the movable cleaning elements in motion. The movable cleaning elements remain in the cleaning chamber during this application.

[0074] For possible configurations of the procedure as well as for definitions, reference can largely be made to the above description of the cleaning device and the cleaning basket.

[0075] The procedure can be carried out in particular such that the application in step iv. is effected by spraying, dripping, irradiation, or a combination of the aforementioned and / or other direct application methods. This can be achieved, for example, by appropriate design and / or control of the application device.

[0076] As explained above, step i. can, in particular, include fixing the items to be cleaned in the cleaning basket. For this purpose, one or more fixing elements can be used, for example.

[0077] As further explained above, the process can be used in particular for cleaning personal protective equipment. Accordingly, the items to be cleaned can include personal protective equipment, especially breathing apparatus, including, for example, respirators and / or one or more gas-carrying elements such as compressed air breathing apparatus.

[0078] In a further aspect, a use of the cleaning device is also proposed, for example, a cleaning device according to one or more of the embodiments described above and / or according to one or more of the embodiments described in more detail below. This proposed use of the cleaning device concerns its use for cleaning personal protective equipment, in particular breathing apparatus.

[0079] The proposed cleaning device, cleaning basket, method, and application offer numerous advantages over conventional devices and methods of a similar nature. In particular, the disadvantages of conventional devices and methods described above can be largely avoided. Specifically, the technical challenge that combustion residues are generally difficult to remove using conventional cleaning fluids, such as water, pressure wash, and corresponding chemical additives, can be addressed, at least partially. Furthermore, the mechanical action prevents an increase in temperature, for example, above 45 °C. The electrostatic adhesion effects can also be largely reduced by the additional mechanical action, through mechanical abrasion with the movable cleaning elements.In general, a cleaning process can be improved by a direct mechanical component of the cleaning, which allows dirt to be removed more effectively.

[0080] The technical implementation of the cleaning device and the cleaning basket can be carried out in a simple manner. For example, in addition to an existing washing system, spherical, thread-like, or ribbon-like solid components can be introduced into the cleaning chamber and / or the cleaning basket as movable cleaning elements for the mechanical processing of the items to be cleaned, in particular for the mechanical abrasion of contaminants.

[0081] For example, movable cleaning elements in the form of spheres can be used. These spheres can be placed in the cleaning chamber. The spheres can be lightweight and, for example, small enough to remain suspended above a lower nozzle system in the cleaning chamber and / or in the cleaning basket. The pressure and / or spray jets of the cleaning device can move the spheres within the cleaning chamber, for example, causing them to be flung around, thus mechanically impacting the items being cleaned and, in particular, abrading away contaminants. The spheres can, for example, have a textile covering, such as a cotton covering. This textile covering can be particularly durable and exhibit little or no abrasion.Furthermore, the textile covering can absorb impurities. Instead of a textile covering, the spheres can also be made entirely of a textile material.

[0082] Alternatively or additionally to the use of spheres, the movable cleaning elements can, in particular, consist of threads, as described above. For example, movable cleaning elements such as a plurality of individual flexible threads can be attached to an upper area of ​​the cleaning chamber, hanging downwards. These threads can rest on the item being cleaned and / or hang beside it. Through the impulse transmission of the cleaning fluid, for example, by the washing pressure and / or the spray jets of the application device, the threads can abrade the surfaces of the item being cleaned and remove contaminants, in addition to the fluidic cleaning action. Materials for the threads include, for example, natural fibers and / or cotton and / or plastic materials such as polyester or polyamides, for example, Nylon®, and / or ethylene propylene diene monomer (EPDM) rubber.However, other materials can also be used in principle.

[0083] Alternatively or additionally to the use of balls and / or threads, the movable cleaning elements can also include, in particular, belts, as described above. For example, movable cleaning elements such as multiple individual belts can be mounted in an upper area of ​​the cleaning chamber, hanging downwards. These belts can rest on the item being cleaned and / or hang beside it. Through the impulse transmission of the cleaning fluid, for example, by the washing pressure and / or the spray jets of the application device, the belts can abrade the surfaces of the item being cleaned and remove contaminants, in addition to the fluidic cleaning action. Textile materials and / or plastic materials are generally suitable for the belts.For example, belts, whether in the form of textile materials and / or strips, can be made from at least one flexible plastic material. In particular, the at least one plastic material can be selected from the group consisting of: polyester; polyamide, for example Nylon®; ethylene propylene diene monomer rubber; polyurethane. Alternatively or additionally, abrasive fleeces can also be used, especially those without abrasive components.

[0084] As also stated above, the cleaning device has at least one release device which simplifies loading and / or unloading the cleaning chamber and prevents, for example, the movable cleaning elements from interfering with this loading and / or unloading process. Alternatively or additionally, undesirable effects caused by the movable cleaning elements during certain program steps, particularly drying, can be avoided. The at least one release device may, in particular, include at least one slide, which may, for example, be located on the ceiling of the cleaning chamber.For example, when activated accordingly, such as when the cleaning chamber is opened, this can push the movable cleaning elements outwards against a side wall of the cleaning chamber, thus making the cleaning chamber and / or the items being cleaned more easily accessible for loading and / or unloading.

[0085] As described above, the movable cleaning elements are arranged wholly or partially within the cleaning chamber and, for example, also attached to the cleaning chamber. Alternatively or additionally, the movable cleaning elements can also be wholly or partially attached to at least one cleaning basket. For example, they can also be wholly or partially attached to a mask holder and / or receptacle for personal protective equipment. Furthermore, the at least one cleaning basket can also, as described above, have at least one cleaning element carrier, which can be, for example, fixed or foldable. A foldable attachment can improve access to the cleaning basket, for example, to a mask holder, and thus also to the mounting of the items to be cleaned in the cleaning basket, such as mounting at least one respirator in a mask holder.The cleaning element carrier can be designed so that it is attached separately in the cleaning chamber and / or can be removed from the cleaning chamber, especially in a simple manner.

[0086] As explained above, the moving cleaning elements are set in motion by the cleaning fluid itself. However, at least one additional mechanism is conceivable by which the moving cleaning elements can be further moved. For example, at least one moving element in the form of an additional drive is conceivable, in particular at least one vibrating plate or at least one suspension that can move in different directions, for example to the right or left and / or back and forth within the cleaning chamber. In this way, the moving cleaning elements can be set in motion in addition to the moving elements.

Furthermore, one or more heating elements 138 can be provided to heat the cleaning fluid 120 in the washing tank 134 and / or other tanks.The wash tank 134 can in turn be emptied into a drain 144, for example via a drain line 140 and optionally via a drain pump 142.

[0093] The application device 118 can further comprise a rinsing line system 146, via which, for example, the rinsing nozzle system 128 can be supplied with a further cleaning fluid 120, for example, with a rinsing liquid 148. In particular, the rinsing liquid 148 can, for example, be supplied from a separate rinsing tank 150 and can preferably also be heated by one or more heating elements 138. For supplying the rinsing nozzle system 128, the application device 118 can, for example, comprise one or more rinsing pumps 152.

[0094] The cleaning device 110 can, in particular, comprise at least one control unit 153. The control unit 153 can, for example, be configured to control a cleaning process, such as a cleaning program, in which the item to be cleaned 112, for example, the at least one cleaning basket 114 containing the item to be cleaned 112, is stationary in the cleaning chamber 116 and is successively exposed to cleaning fluid 120 in different ways in one or more cleaning steps of the cleaning program, for example, first in at least one washing step with at least one washing fluid and in at least one rinsing step with at least one rinsing fluid 148. Furthermore, at least one drying step can be provided, which, for example, can be located in one of the cleaning chambers 116 after the item to be cleaned 112 has been stationary in the cleaning chamber.

[0095] The cleaning device 110 further comprises a plurality of movable cleaning elements 154, wherein the movable cleaning elements 154 are arranged to be movable relative to the cleaning basket 114. In particular, the movable cleaning elements 154 are configured to remain in the cleaning chamber 116 during the exposure of the item to be cleaned 112 to the cleaning fluid 120. Furthermore, the movable cleaning elements 154 are configured to be set in motion by the cleaning fluid 120, in particular by a flow of the cleaning fluid 120, and wherein the movable cleaning elements 154 are configured to exert a mechanical cleaning effect on the item to be cleaned 112 during the exposure of the cleaning fluid 120.

[0096] For example, the mobility of the movable cleaning elements 154 can be designed such that the cleaning elements 154 can move freely in the cleaning chamber 116. This can be the case, for example, if the movable cleaning elements 154, or at least a part of the movable cleaning elements 154, comprise a plurality of solid bodies, for example spheres 156, which are arranged in Figure 2 The figures are illustrated by way of example, which are freely movable within the cleaning chamber 116 but cannot leave the cleaning chamber 116. Alternatively or additionally, the movable cleaning elements 154 can also be designed with only partial mobility, at least in part. This partial mobility is illustrated by way of example in Figure 1The embodiment shown is illustrated and can be achieved, for example, by attaching the movable cleaning elements 154 with at least one part, for example, with a first end 158. For example, the cleaning elements 154, in particular with the first end 158, can be attached to at least one wall of the cleaning chamber 116 and / or to the cleaning basket 114. Alternatively or additionally, the cleaning elements 154 can be attached with the first end 158 to a suspension 160, for example, a grid, provided in the cleaning chamber 116. As shown in the Figure 1As illustrated in the embodiment shown, the suspension 160 can be used in particular when rotatably and / or pivotably mounted elements are arranged within the cleaning chamber 116 above the cleaning basket 114, for example in the embodiment shown here the nozzle arm 126 and the rinse nozzle arm 130 of the application device 118.
