Description

Technology Field

[0001] The present invention relates to a cleaning basket for cleaning a breathing device or components of a breathing device and optionally disinfecting them. Additionally, the present invention relates to a cleaning system and method for cleaning a breathing device. Such devices and methods may generally be used to clean breathing devices or their components for emergency services, such as firefighters, technical support agencies, or rescuers; for divers or persons working in generally hostile or dangerous environments; and for members of the military and security forces, such as police officers. The proposed devices and methods may also be used for breathing devices in the medical sector, for example, breathing masks for supplying oxygen and performing tasks. Other applications may also be considered. Background Technology

[0002] For example, breathing devices such as protective breathing masks or breathing regulators generally form part of personal protective equipment, for instance, in emergency services, the military, or security forces. For instance, numerous breathing devices for various uses are known in the prior art. For instance, emergency responders, such as firefighters, use protective breathing masks with filters to remove harmful components from the inhaled breathing air. However, in many cases, what are called breathing regulators are used as an alternative to or in addition to filters, allowing the user to ventilate with a breathing gas, such as compressed air. Breathing regulators, often referred to as respiratory regulators, generally allow the user to breathe from a compressed gas cylinder or other compressed gas connection, thereby enabling the user to remain in, for instance, underwater or in other breathable or toxic atmospheres. To this end, the compressed gas, for instance, compressed air, coming from the compressed gas connection is adjusted by the breathing regulator to match the prevailing pressure in the user's working environment.

[0003] A breathing device or its components must generally be cleaned, sterilized, dried, inspected, and, if necessary, repaired and packaged after each use. Cleaning is intended to remove all contamination resulting from use or storage, ensuring that the breathing device is presented in a visually clean and hygienically satisfactory condition for, for example, the next preparation step. These requirements generally apply to other components of the breathing device, such as additional parts of the breathing mask like filters or breathing regulators, and accessories.

[0004] In many cases, respiratory devices, such as breathing masks and their accessories, are washed manually or in a modified washing machine with the help of a protective bag and / or an adapter. For example, EP 0 935 687 B1 discloses a washing machine having a drum, generally. The outer shell of the drum has a structure protruding toward the interior of the drum, and there is a hole at the corner point of the outer contour of the protrusion toward the interior of the drum. Using such a washing machine, in principle, items of emergency service equipment can be washed particularly gently.

[0005] EP 1 088 928 A1 discloses a holding system for a protective breathing mask in a laundry processing machine. The holding system has a carrying strut that is positioned within the drum of the laundry processing machine to rotate together and to which the protective breathing mask can be connected.

[0006] DE 200 03 743 U1 and DE 298 22 172 U1 each disclose a protective clothing processing device. In this case, a hanger consisting of a flexible air outlet nozzle is used. The hanger is fixed to a rotating device. Cleaning the breathing apparatus is generally impossible or difficult using only the depicted device.

[0007] DE 10 2015 108 857 A1 also discloses a method for treating at least one protective suit, in particular a chemical protective suit, and the method is:

[0008] a) a step in which at least one processing adapter is connected to at least one opening of the protective suit in a releaseable and sealed manner, and

[0009] b) a step in which a cleaning and disinfecting solution is delivered into the interior of a protective suit through at least one processing adapter, and the cleaning and disinfecting solution delivered into the interior of the protective suit is discharged from the protective suit, and

[0010] c) a step in which a drying gas for drying the protective suit is delivered into the interior of the protective suit through at least one processing adapter, and the drying gas delivered into the interior of the protective suit is discharged from the protective suit, and

[0011] d) includes the step of separating at least one processing adapter from at least one opening of the protective suit.

[0012] DE 10 2005 033 618 B3 discloses an apparatus for washing a protective breathing mask. The apparatus comprises a housing that can be closed and at least one receptacle disposed within at least one carrier for a protective breathing mask. A nozzle apparatus and a brush apparatus are also provided, allowing the protective breathing mask to be moved to wash it. However, it is not possible to individually place and wash the accessory parts of the mask using the disclosed apparatus. Furthermore, washing gas delivery elements, such as a breathing regulator, for example, is not possible with the disclosed apparatus. DE 200 03 744 U1 also discloses an apparatus for washing, disinfecting, and drying a protective breathing mask having a placed nozzle system and a transport frame with individual processing positions. In principle, this apparatus is not suitable for washing gas delivery elements and accessory parts either.

[0013] DE 10 2007 009 936 A1 discloses a cleaning device for a compressed air breathing apparatus. The device has a receiving space surrounded by a protective grid and a rotating nozzle carrier. In this case, the nozzle carrier is located outside the protective grid. However, a disadvantage of the presented device is that the cleaning fluid can penetrate into the gas delivery area.

[0014] In contrast, cleaning of sensitive components of breathing devices, such as breathing regulators, is generally performed manually. If necessary, manual cleaning can be supported by placing them in an ultrasonic cleaning device. However, DE 10 2007 012 768 B4 discloses a method and apparatus for cleaning breathing regulators. In this case, the article to be cleaned is mounted on a holder of a rotating element and repeatedly immersed in a liquid bath containing a cleaning solution, a disinfecting solution, and a rinsing solution. The breathing regulator is first filled with compressed air to provide a seal between the valve and the tube connection, and then immersed in the liquid bath. However, a disadvantage of this immersion method is that a complex holder having a corresponding actuator is required to ensure that the cleaning solution is removed from various cavities by appropriate movement after cleaning.

[0015] DE 100 20 835 A1 discloses an apparatus for handling a protective breathing mask. A receptacle for receiving a protective breathing mask is provided, wherein the protective breathing mask is coupled to the receptacle by a breathing device connection. Additionally, a collection device for collecting a treatment agent and a pump for supplying a treatment agent are provided within a compartment of the apparatus.

[0016] US 3,881,503 A discloses an apparatus for cleaning and decontaminating articles of anesthesia equipment. A nozzle system is provided as a means for spraying a water jet at high pressure onto an article to be cleaned.

[0017] DE 11 74 169 B discloses a device for washing a protective breathing mask. In this case, a tubular frame is provided in the housing so as to be rotatably mounted, whereby the mask to be washed is spread out over a holder. By means of the rotating frame, the protective breathing mask is moved in a rotational motion through a washing solution tank within the container.

[0018] WO 2011 / 144518 A2 discloses a cleaning device for cleaning a breathing device. The cleaning device comprises at least one cleaning chamber for receiving at least one breathing device and at least one fluid device for applying at least one cleaning solution to the breathing device. The cleaning device also has at least one pressurizing device having at least one pressure connection. The pressure connection may be connected to at least one gas delivery element of the breathing device. The pressurizing device is configured to fill the gas delivery element with compressed gas.

[0019] DE 10 2012 220 646 B3 discloses a product range for cleaning a breathing device comprising at least two holders. In this case, a first holder for cleaning a breathing mask with a pressurizing device and a second holder for cleaning a support frame are provided.

[0020] Despite the advantages achieved by the aforementioned devices and methods, numerous technical challenges remain. In the case of protective breathing masks, also known as respirators, technical issues include the fact that many have structurally complex designs and contain cavities where cleaning fluid can accumulate. Specifically, liquid detergent tends to collect primarily during and after the cleaning program in sealed areas, which are typically configured in a maze-like manner. While these liquid residues must generally be manually emptied from the cleaning unit after the protective breathing mask is removed, this can compromise the hygiene of the cleaned mask. Furthermore, manual emptying entails additional operational costs for the cleaning unit. Conversely, if the protective breathing mask is not sufficiently emptied, the drying time increases accordingly during subsequent drying, either within the cleaning unit itself or, for example, in a separate drying cabinet. Another problem related to liquid residues within the protective breathing mask is that, particularly when the mask is removed from the cleaning unit, the residue can spill onto the floor of the work area. This can pose a risk of accidents in the workplace. The problem to be solved

[0021] Accordingly, it would be desirable to provide a washing basket, a washing system, and a method for washing and optionally disinfecting a breathing device, which at least substantially prevents the disadvantages of the known devices and methods of the above-mentioned type. In particular, the present invention is intended to enable washing of a protective breathing mask, including sufficient sterilization and rapid drying of the protective breathing mask compared to conventional devices and methods, while simultaneously reducing the risk of accidents caused by leakage of the washing solution, particularly liquid detergent leakage. means of solving the problem

[0022] This objective is achieved by a cleaning basket, a cleaning system, and a method for cleaning and optionally disinfecting a breathing apparatus, having the features of the independent patent claim. Advantageous improvements that can be realized individually or in any desired combination are presented in the dependent claims.

[0023] In the following, the terms "have," "consist of," or "include," or grammatical variations derived therefrom, are used in a non-exclusive manner. Thus, these terms may relate to both situations in which there are no additional features or situations in which there is one or more additional features, in addition to the features introduced by these terms. For example, the expressions "A has B," "A consists of B," and "A includes B" may relate to both situations in which A has no additional elements except for B (i.e., situations in which A consists only of B), and situations in which, in addition to B, A has one or more additional elements, e.g., element C, elements C and D, or more additional elements.

[0024] Furthermore, the terms "at least one" and "one or more," and their grammatical variations, are generally used only once—for example, when the feature or element is first introduced—when they are used with one or more elements or features, and when it is intended to indicate that an element or feature may be provided once or multiple times. When the feature or element is mentioned again later, the corresponding terms "at least one" or "one or more" are generally no longer used and do not limit the possibility that the feature or element may be provided once or multiple times.

[0025] Furthermore, the terms “preferably,” “particularly,” “for example,” or similar terms used below are used in conjunction with optional features, and alternative embodiments are not limited accordingly. In this regard, the features introduced by these terms are optional features and are not intended to limit the scope of protection of the claims, particularly independent claims. In this regard, as will be recognized by those skilled in the art, the present invention may also be performed using other configurations. In a similar manner, features introduced by “in one embodiment of the present invention” or “in one exemplary embodiment of the present invention” should be understood as optional features and are not intended accordingly to limit alternative configurations or the scope of protection of independent claims. Furthermore, such introductory expressions are not intended to affect any possibility of combining features introduced by them with other features, whether optional or non-optional.

[0026] In a first aspect of the present invention, a cleaning basket for cleaning a breathing device is proposed.

[0027] The term "washing basket" as used herein, also referred to as a "washing basket," is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. This term is not limited to any specific or adopted meaning. The term may, without limitation, relate to a portable receiving device in which, in particular, an article to be washed can be received, which may be introduced into a washing device, e.g., a dishwasher, and which can be removed from the washing device after being washed. Alternatively, the washing basket may be permanently installed, for example, in a washing device. For example, the washing basket may be fixed to a rail system of the washing device, which may be pushed into the washing chamber of the washing device via said rail system, and which may be pushed out of the washing chamber after washing. Additionally, the washing basket may be used to temporarily store an article to be washed. The washing basket may have multiple openings, particularly to allow liquid to drip downward. The washing basket may have a substantially rectangular configuration, and the bottom of the basket may have, for example, a square or generally rectangular outline and may have a support surface for placing the washing basket on a flat work surface. Optionally, one or more basket walls may extend upward from the bottom of the basket, for example, having protruding edges and also optionally other elements such as handles.

[0028] As used herein, the term "breathing device" is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. The term is not limited to any specific or adopted meaning. The term may, without limitation, relate to a device configured in an appropriate manner, particularly to protect a user's airway from harmful effects. For example, a breathing device may be a device configured to filter ambient air completely or partially and / or to provide breathing gas to at least one user. Such a breathing device may be a complete breathing device or a component thereof prepared for operation, and thus, for the sake of terminology, no distinction is made below between a breathing device and its components.

[0029] The breathing device may include at least one protective breathing mask, specifically also referred to as a breathing mask. As used herein, the term “protective breathing mask” is a broad term to which the customary and general meaning understood by those skilled in the art is given. This term is not limited to any specific or adopted meaning. This term may, without limitation, relate to a device that is a component of the breathing device and is configured to cover all or part of the user’s face, particularly the mouth and / or nose area. The covering may serve to protect the user’s airway from hazardous substances and / or to allow breathing gases to enter the airway and / or to expel breathing gases out of the airway. The protective breathing mask may also cover the user’s face and / or head, for example, other parts of the eyes. Accordingly, the protective breathing mask may also specifically have at least one transparent viewing window. The protective breathing mask may also have at least one seal to seal the internal space of the protective breathing mask from the outside, wherein the internal space is surrounded, for example, by the protective breathing mask itself, the user’s head, and the seal of the protective breathing mask during operation of the protective breathing mask. In particular, the protective breathing mask may have a convex design and may form at least one cavity that is partially closed by the protective breathing mask and whose edge is formed, for example, by at least one seal. In particular, the protective breathing mask may preferably be configured to be fully or partially flexible and may have walls that cover the mouth and nose and optionally other areas of the face, for example, the eyes. The seal may have at least one sealing lip that seals the protective breathing mask against the face, in particular, such that the internal space between the face and the protective breathing mask is designed as a sealed area.Additionally, the protective breathing mask may have at least one fastening device for securing it to the user's head, as described in more detail below, such as at least one belt, at least one fastening band, or at least one fastening device consisting of multiple bands, commonly referred to as banding or webbing. The breathing mask may have at least one opening, for example, and may be configured to enable, for example, air supply or breathing gas supply. For example, the breathing mask may have at least one thread for connecting the breathing gas supply. Additionally, the protective breathing mask may have, for example, at least one exhalation valve. The protective breathing mask may be manufactured wholly or partially from, for example, a flexible material, particularly at least one elastic material, for example, rubber and / or silicone.

[0030] Additionally, the breathing device may include additional components. In particular, the breathing device may further include at least one of a tube, a valve, a filter, a compressed gas container, a breathing regulator, or a combination of said elements and / or other elements.

[0031] As used herein, the term "cleaning" is a broad term endowed with the customary and general meanings understood by those skilled in the art. The term is not limited to any specific or adopted meaning. The term may, without limitation, relate to operations in which attached large and small impurities are removed from the article to be cleaned and / or at least partially removed. Additionally, a disinfecting effect may optionally be performed.

[0032] A proposed cleaning basket for cleaning a breathing device comprises at least one basket rack. Additionally, the cleaning basket comprises at least one mask holder for holding at least one protective breathing mask in the cleaning basket. Additionally, the cleaning basket comprises at least one suction element configured to extend into the protective breathing mask held by the mask holder, having at least one suction opening. The suction element is configured to be charged with negative pressure and to draw cleaning fluid into the suction opening from at least one internal space of the protective breathing mask. This negative pressure charging may be performed particularly while or after the cleaning fluid is applied to the breathing device.

[0033] As used herein, the term "basket shelf" is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. The term is not limited to any specific or adopted meaning. The term may, without limitation, relate to the mechanical basic structure of a washing basket, in particular, which may have a basket bottom, and additionally, one or more basket walls that may extend from the basket bottom. The basket shelf may be manufactured wholly or partially from at least one material selected from the group consisting particularly of plastic and metal. The basket shelf may be composed, for example, wholly or partially of a wire rack, for example, a wire grating. Alternatively or additionally, the basket shelf may also be composed wholly or partially of a plastic rack having a number of openings, such as a plastic rack, for example, a plastic grating. In particular, the basket shelf may have one or more openings to allow, for example, washing liquid to flow out of the interior of the basket shelf. The basket shelf may have a rectangular basic structure wholly or partially, for example, with a rectangular support surface.

[0034] As used herein, the term “mask holder” is a broad term to which the customary and general meaning understood by those skilled in the art is given. The term is not limited to any specific or adopted meaning. The term may relate, without limitation, to a device configured to hold at least one protective breathing mask, particularly during a washing operation. The mask holder may have, in particular, at least one projection that extends from the washing basket, particularly from the bottom and / or wall of the washing basket, for example, into the internal space of the washing basket and / or upward from the washing basket, and is configured to hold and / or secure at least one protective breathing mask, particularly at a distance from the bottom of the washing basket. The mask holder may be manufactured, for example, wholly or partially from at least one plastic and / or wholly or partially from at least one metal material. The mask holder may also be wholly or partially connected to the basket shelf or formed integrally with the basket shelf.

[0035] As used herein, the term “suction element” is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. This term is not limited to any specific or adopted meaning. This term may relate, without limitation, to a device or element configured to remove at least one fluid from an area designated by a suction operation, particularly by the application of negative pressure. In particular, the suction element may have at least one element selected from the group consisting of pipes, tubes, and channels, wherein the element has at least one opening through which fluid can enter the element, and the element itself is filled with negative pressure. For example, the element may have at least one connection to at least one negative pressure source or vacuum source, or at least one connection for connection to at least one negative pressure source or vacuum source, wherein the connection is fluidly connected to at least one opening, which may also be referred to as a suction opening.

[0036] Accordingly, the term "suction opening" as used herein is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. This term is not limited to any specific or adopted meaning. The term may, without limitation, relate to an opening, particularly in the wall of a suction element, through which an opening fluid can enter an internal space, such as the lumen of the suction element, which can be filled, for example, with negative pressure. In principle, the opening may have any desired cross-section, for example, a circular, elliptical, or polygonal cross-section. For example, a single opening or multiple openings may be provided in the wall of the suction element. For example, at least one suction opening may include at least one passage opening in the wall of at least one pipe, tube, or channel of the suction element.

[0037] The suction element may be connected to the mask holder wholly or partially and / or integrated therein. Thus, the suction element may also be formed, for example, as a component of the mask holder and / or connected to the mask holder in a fixed or releaseable manner. Alternatively or additionally, however, the suction element may also be connected wholly or partially in a fixed or releaseable manner to other components of the washing basket, or integrated wholly or partially into other components of the washing basket. The suction element may therefore also be connected to the basket shelf. Fixed or releaseable connections may also be considered here. For example, the suction element may be connected releaseably to one or another component of the washing basket, for example, the basket shelf or the mask holder, and configured to be removed, for example, for washing purposes.

[0038] As described above, the suction element is configured to extend into the protective breathing mask held by the mask holder. Accordingly, the suction element may have a particularly long element, for example, an element whose longitudinal range exceeds the lateral range by at least two, for example, at least three times. Accordingly, the suction element may be configured, for example, as a tube or pipe or as a loop of a tube or pipe, to extend into at least one internal space of the protective breathing mask. In terms of the space, the suction element may be positioned in such a way that it protrudes particularly from the mask holder, so that the suction element extends into the internal space formed, for example, by the wall of the protective breathing mask facing the mask holder when the protective breathing mask is received in the mask holder. The suction element may be configured rigidly, or preferably flexibly, as described in more detail below, so that the suction element may be flexibly introduced, for example, into the internal space, or specifically introduced, for example, into the space of the seal of the protective breathing mask to suction a cleaning solution.

[0039] Additionally, as described above, the suction element is configured to be charged with negative pressure. As described above, this negative pressure charging and the resulting suction operation may be performed while at least one cleaning solution is applied to the breathing device, or after the cleaning solution is applied, for example, during or before the drying step. By charging the suction element with negative pressure, the cleaning solution is drawn into the suction opening from at least one internal space of the protective breathing mask. To this end, as described above, the suction element may have at least one lumen, for example, a lumen of the pipe, tube, or channel of the suction element, enclosed by the wall of the suction element. Here, the suction opening may penetrate, for example, the wall surrounding the lumen, and thus the cleaning solution may enter the lumen through the suction opening. The lumen may be particularly long. The lumen may be connected to at least one negative pressure source, also known as a vacuum source, at at least one connection point, for example, at least one port or other type of connection point.

[0040] As used herein, the term “cleaning fluid” is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. This term is not limited to any specific or adopted meaning. The term may, without limitation, refer to a liquid capable of carrying out a cleaning operation, particularly when impacting an article to be cleaned. Accordingly, the term “liquid detergent” is also used hereinafter instead of the term “cleaning fluid” without limiting the use of other fluids. In particular, liquid detergent may comprise an aqueous liquid, e.g., water and / or water containing one or more additives, e.g., one or more detergent concentrates and / or rinse aids and / or disinfectants. The cleaning fluid may be applied to a breathing device in a manner in which individual liquid detergents are used or in a manner in which a combination of multiple liquid detergents is used. If multiple liquid detergents are provided, various liquid detergents may be applied simultaneously or sequentially. A cleaning basket with a breathing device may be maintained in a stationary manner, for example, within the cleaning chamber of a cleaning device, and various liquid detergents and / or cleaning fluids may be applied continuously.

[0041] As explained above, the cleaning solution comprises at least one cleaning solution selected from the group consisting particularly of an aqueous cleaning solution; a cleaning solution containing at least one cleaning agent solution; a cleaning solution containing at least one rinse aid; a cleaning solution containing at least one disinfectant; a post-rinsing fluid; demineralized water; and a heated cleaning solution, particularly a cleaning solution heated to a temperature of 30°C to 70°C, particularly preferably 60°C.

[0042] The phrase "the cleaning solution is applied" can generally be understood to mean bringing an article to be cleaned, in this case a breathing mask, into contact with at least one cleaning solution. This may be accomplished by direct application, for example, by spraying, dripping, atomizing, or a combination of the above and / or other direct forms of application, in which the cleaning solution directly strikes the article to be cleaned, e.g., a breathing device and / or breathing mask. Such forms of application may occur particularly in the case of a fixed cleaning chamber. Alternatively or additionally, application may also be performed in such a way that the cleaning chamber is completely or partially filled with cleaning solution so that the article to be cleaned, contained in the cleaning chamber, comes into contact with the cleaning solution at at least one location within the cleaning chamber. Such forms of application may be used particularly in the case of a configuration of the cleaning chamber as a movable cleaning chamber, for example, in the form of a drum. Combinations of the above forms of application and / or other forms of application are also possible. Regardless of whether the cleaning chamber is configured to be fixed or movable, the cleaning solution may be applied in a simple operation mode where it is applied only once to the article to be cleaned, e.g., a breathing device and / or breathing mask. However, alternatively or additionally, cleaning may be performed in a circulating operation mode in which a cleaning solution is repeatedly applied to the items to be cleaned. Such a circulating operation mode and a circulating circuit are known, for example, in conventional washing machines.

[0043] The suction element may have at least one element selected from the group consisting of, in particular, a suction pipe having at least one suction opening, particularly a curved suction pipe; a suction tube having at least one suction opening; a U-pipe having at least one suction opening; a pipe loop; a disc-shaped suction element having at least one suction opening; and a spoon-shaped suction element having at least one suction opening. Other forms are also possible in principle. For example, other pipe-shaped or tubular elements are also possible in principle. Alternatively or additionally, one or more suction elements that do not have a pipe shape but have, for example, at least one suction opening and at least one internal structure through which a cleaning solution can be sucked may also be used. For example, as described above, a disc-shaped or spoon-shaped element in which a protective breathing mask is retained and / or accommodated in a cleaning basket may also be considered. This element may have at least one suction opening, for example, at the lowest point, and the cleaning solution may be sucked, for example, through the entire internal space or through an integrated channel.

[0044] As described above, the suction element can be configured to be flexible, particularly elastic, especially at least partially, for example, at least in cross-section. Thus, the suction element can be configured to be deformable, for example, where the deformation can be enabled by a force that can be applied manually. The deformation can be plastic or elastic. Accordingly, the suction element can be manufactured from a metal pipe or plastic pipe that is deformable or bendable, for example, plastically or elastically. For example, the use of expansion bellows to allow for deformation can also be considered.

[0045] In particular, the inhalation element may have at least one inhalation pipe and / or at least one flexible tongue for introduction into the internal space of the protective breathing mask. The flexible tongue may be designed, for example, as a conductive loop or as a curved end of the pipe or tube of the inhalation element. In particular, at least one inhalation opening may be introduced into the flexible tongue, and thus, when the flexible tongue extends into the internal space of the protective breathing mask, the inhalation opening may be positioned within the internal space of the protective breathing mask. Alternatively, or additionally, the inhalation element may be configured such that flexibility does not arise solely from its shape or material, but rather a rigid inhalation element is elastically or elastically fixed and thus easily introduced into the internal space of the breathing mask.

[0046] The suction element can be connected directly or indirectly to the mask holder, and specifically, can be integrated at least partially into the mask holder. In particular, the suction element can be integrated into the mask holder in such a way that the suction opening is positioned between the basket shelf and the point of the mask holder that protrudes furthest from the basket shelf. This can particularly serve to position the suction opening at the lowest possible point inside the protective breathing mask, where the cleaning solution collects due to gravity.

[0047] As described above, the basket shelf may specifically have at least one shelf bottom and a shelf wall. The shelf bottom and / or shelf wall may specifically be manufactured from at least one metal material and / or at least one plastic material, either wholly or partially. The mask holder and the suction element may be connected to the basket shelf in a fixed or releaseable manner.

[0048] In particular, the mask holder may have at least one protrusion extending from the basket shelf. A protective breathing mask may be attached to or unfolded, for example, the protrusion.

[0049] The mask holder may have a wire rack, for example, made of rounded wire, specifically to prevent damage by sharp edges as a sensitive protective breathing mask is unfolded over it. The wire rack may be made of metal or, for example, plastic material.

[0050] The cleaning basket may have at least one suction line. The suction line may be designed, for example, as a pipe, tube, or channel, and may be fixedly connected to, for example, a basket shelf or integrated into the basket shelf, for example, the bottom of the basket on the basket shelf. A suction element may be fluidically connected to the suction line. For example, the suction element may be integrally connected to the suction line or configured independently of the suction line but fluidly connected thereto. In particular, the lumen of the suction element may be connected to or connected to the lumen of the suction line. The suction line may have at least one connection for a connection of a suction device, particularly a detachable connection, which may be a component of the cleaning device, particularly wholly or partially. Thus, at least one connection may have a pressure port or a screw connection to which, for example, the cleaning basket may be introduced or to which the vacuum line of the introduced cleaning device is connected. The pressure port may have a quick-acting closure, such as a bayonet closure.

[0051] At least one suction line may be connected, and the suction device, which will be described in more detail below, may be wholly or partially integrated into a washing device that accommodates at least one washing basket. Alternatively, or additionally, the suction device may be at least partially integrated into the washing basket. For example, components of the suction device, such as the Venturi nozzle described in more detail below, may be located on or directly within the washing basket, and may be connected to or integrated into the basket shelf, for example. In this case, for example, the suction line may be connected directly or indirectly to the suction device, which may be wholly or partially integrated into the washing basket, or connected in a fixed or releaseable manner, and a fixed or releaseable connection may also be considered.

[0052] If the suction device is fully or partially integrated into the cleaning basket, the cleaning device may, for example, support or operate the suction device, or charge it with energy. In particular, if the suction device has at least one pump, such as a venturi nozzle, for example, the suction device may be configured to be charged with compressed air by the cleaning device. In this case, a negative pressure supply on the cleaning device side is not absolutely necessary.

[0053] Integrating the suction device completely or partially into the washing basket can also be advantageous for reasons of configuration space. For example, the configuration space of the suction device can be saved within the washing device itself.

[0054] A configuration in which the suction device is wholly or partially integrated into the washing basket can also be used to accommodate articles to be washed, particularly depending on the type of article. For example, a protective breathing mask may be accommodated in the washing basket according to the present invention, and a breathing regulator may be accommodated in another washing basket, for example, as disclosed in WO 2011 / 144518 A2. In the latter case, the washing device may, in any case, already have a pressurizing device, for example, a compressed air supply source that can also be used to operate the suction device, and the desired timing sequence of pressurization may be activated by the controller of the washing device, for example, by a valve connected upstream, for example, by the selection of a corresponding washing program. For example, pressurization may occur continuously while washing the breathing regulator, whereas pressurization and the consequent operation of the suction device may occur only, for example, at the end of the rinsing operation while washing the protective breathing mask.

[0055] A number of different types of cleaning baskets, including the cleaning basket proposed herein, may be used in the cleaning device. In this context, it may be considered that the cleaning basket, particularly the cleaning basket proposed herein, is coded and has, for example, at least one identifier. The at least one identifier may include at least one optical, electronic, or magnetic identifier, such as, for example, a barcode or an RFID label. For example, purely mechanical coding and scanning by an electromagnetic cam switch may also be considered. Generally, the cleaning device may be configured to identify, for example, the cleaning basket and correspondingly select and / or adjust the cleaning program in a manner, for example, particularly controlled by a controller. Such identification may be performed, for example, through at least one sensor of the cleaning device.

[0056] As described above, the wash basket is composed of a suction element for drawing out the wash fluid that has penetrated the protective breathing mask of the breathing device from the internal space of the protective breathing mask. However, the wash basket may also be configured to protect at least one gas delivery element of the breathing device by pressurization during washing with the wash fluid, for example, as disclosed in WO 2011 / 144518 A2. Accordingly, the wash basket may also have at least one pressure connection that can be connected to at least one gas delivery element of the breathing device, wherein the gas delivery element may be filled with compressed gas while the wash fluid is applied to the breathing device. In this way, drawing out the undesirably penetrated wash fluid from the internal space of the protective breathing mask can be combined with effectively preventing the wash fluid from undesirably penetrating at least one gas delivery element, for example, the breathing regulator. To further create a mechanical connection to the breathing device, the pressure connection may include, in particular, at least one form-fitting and / or force-fitting connection element, in particular a quick-acting coupling and / or thread. The washing basket may have a releaseable compressed gas connection for connecting a pressure connection, in particular, to a washing device, specifically a pressurizing device of a washing device into which the washing basket can be introduced.

[0057] As explained above, the pressure connection may also be used for suction, particularly when the suction device is wholly or partially integrated into the cleaning basket. Therefore, the pressure connection can have multiple functions.

[0058] As described above, the cleaning basket may be configured to clean a breathing device having at least one protective breathing mask and optionally at least one gas delivery element. However, the cleaning basket may also be configured to clean additional components of the breathing device. Thus, at least one small component basket for accommodating small components of the breathing device, in particular a closeable small component basket with a basket cover, may be additionally placed in the cleaning basket.

[0059] In a further aspect of the present invention, a cleaning system is proposed for cleaning a breathing device, in particular for cleaning a breathing device having at least one protective breathing mask and optionally at least one breathing regulator. The cleaning system is:

[0060] - At least one washing basket according to the present invention, for example according to one or more of the configurations described above and / or according to one or more of the embodiments described below; and

[0061] - It includes at least one cleaning device, and the cleaning device has at least one cleaning chamber for accommodating at least one cleaning basket, and the cleaning device also includes at least one application device for applying at least one cleaning solution to the breathing device.

[0062] The cleaning system also includes at least one suction device configured to generate negative pressure and connected to the suction element of the cleaning basket. As described above, the suction device may be integrated here wholly or partially into the cleaning system. Alternatively, or additionally, the suction device may also be integrated wholly or partially into the cleaning basket.

[0063] As used herein, the term "cleaning system" is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. This term is not limited to any specific or adopted meaning. This term may, without limitation, relate in particular to a system, that is, a whole of at least two functionally interacting components, said system providing cleaning within the meaning of the definition above.

[0064] As used herein, the term “washing device” is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. The term is not limited to any specific or adopted meaning. The term may relate, without limitation, to a device configured to remove, or at least partially remove, attached large and small impurities from an article to be washed. Additionally, a disinfection effect may optionally be performed. As further described below, the washing device may consist particularly of a dishwasher, particularly a dishwasher. The dishwasher may consist, for example, of a single-chamber dishwasher, particularly a commercial single-chamber dishwasher with a multi-circuit rinsing system, a front-loading machine or a hood-type dishwasher, particularly a pass-through washer. A dishwasher capable of water exchange, particularly referred to as a single-circuit system, may also be used. Other types of washing devices may also be used as an alternative to or in addition to the dishwasher.

[0065] The washing device comprises at least one washing chamber. As used herein, the term "washing chamber" is a broad term to which the customary and general meaning understood by those skilled in the art is given. This term is not limited to any specific or adopted meaning. This term may, without limitation, relate to a completely or partially closed chamber in which, in particular, washing operations can be performed entirely or partially. The washing chamber may have at least one housing that encloses the washing chamber wholly or partially. A single washing chamber may be provided herein, or, in principle, a plurality of washing chambers may be provided, for example, sequentially. The washing chamber may have at least one opening for, for example, loading articles to be washed into the washing chamber. For example, this single opening may be provided with a cover disposed on the front and / or top surface of the washing chamber. Alternatively, a hood for closing the washing chamber is also possible, for example, within the scope of what are called hooded dishwashers or pass-through dishwashers. Other configurations are also possible in principle.

[0066] The washing chamber is configured to accommodate at least one washing basket. To this end, the washing chamber may have, for example, at least one basket receptacle into which the washing basket can be pushed, for example, at least one rail, and / or at least one holding device or transfer device through which the basket can be transported into, out of, or through the washing chamber.

[0067] The cleaning device may also have at least one dispensing device for applying at least one cleaning solution to the breathing device. The dispensing device may be configured to apply at least one cleaning solution to the breathing device, particularly within the cleaning chamber. The dispensing device may have, for example, at least one tank for receiving at least one cleaning solution and, for example, one or more nozzles. In particular, the dispensing device may have at least two nozzle arms, for example, received in the cleaning chamber. Additionally, the dispensing device may have additional elements, for example, one or more pumps and one or more pipelines for transferring the cleaning solution to at least one nozzle. The dispensing device may be controlled, in particular, by at least one controller of the cleaning device.

[0068] As used herein, the term “dispensing device” is a broad term to which the customary and general meaning understood by those skilled in the art is given. This term is not limited to any specific or adopted meaning. This term may relate, without limitation, to any desired device in which, in particular, at least one cleaning solution, in particular at least one liquid detergent, can be applied to an article to be cleaned within a cleaning chamber. The dispensing device has, for example, at least one nozzle system having at least one nozzle, for example, one or more nozzle arms that may be positioned above and / or below the article to be cleaned. Additionally, the dispensing device may include at least one pump and at least one delivery system for supplying liquid detergent to the nozzle system. For example, a nozzle system and a line system for dispensing liquid detergent from a tank, and also at least one corresponding pump may be provided. Alternatively or additionally, for example, at least one nozzle system may be supplied from a supply line without requiring a pump for this purpose. The cleaning device may be configured specifically as a cleaning device having two tanks, a cleaning tank and a rinsing tank. Accordingly, the dispensing device may particularly include a washing system and a rinsing system, wherein, for example, the washing system may have a washing tank and a washing nozzle system and also a washing line system and a washing pump, for example, a recirculation pump. The rinsing system may have, for example, a rinse tank separated from the washing tank, a rinse nozzle system, a rinse line system, and optionally a rinse pump. The rinse nozzle system and the washing nozzle system may be formed separately, for example, wholly or partially. However, the nozzle system may also be optionally combined, for example, wholly or partially, within a common housing.

[0069] As described above, the dispensing device may have at least one nozzle in particular. The at least one nozzle may include at least one nozzle selected from the group consisting of, in particular, a spray nozzle; a rinse nozzle; a spray arm, in particular a rotatable spray arm; and a nozzle capable of operating in a recirculation operation mode.

[0070] The washing device may be configured to perform at least one washing program in a manner controlled, for example, by an application device, for example by at least one controller of the washing device, wherein an article to be washed, for example, at least one washing basket with a breathing device, is received in a fixed manner in a washing chamber, and a washing solution is applied sequentially in a different manner in one or more washing steps of the washing program, for example, at least one washing step using at least one washing solution first and at least one rinsing step using at least one rinsing solution. Additionally, at least one drying step may be provided, which is placed after the application of the washing solution in one washing chamber when the article to be washed is received in a fixed manner, for example. Thus, the washing device may be configured as an automatically programmed washing machine. However, alternatively, the washing device may be configured as a transfer washing machine in which, for example, a washing basket with a breathing device is transported through one or more washing zones.

[0071] The term “tank” as used herein is a broad term to which the customary and general meaning understood by those skilled in the art is given. This term is not limited to any specific or adopted meaning. This term may relate, without limitation, to a fully or partially closed container configured to contain, in particular, at least one fluid, specifically at least one liquid. As described above, the at least one tank may, for example, have at least one wash tank. The at least one wash tank may, for example, be placed at the bottom of a wash chamber so that the wash fluid can flow from the wash chamber to the wash tank, or may be fluidly connected to the bottom of the wash chamber. For example, the wash tank may be separated from the wash chamber by at least one filter. In addition to the at least one wash tank, the at least one tank may include one or more additional tanks. Thus, the at least one tank may have at least one rinse tank that may be formed separately from the wash tank, for example. For example, the at least one rinse fluid may be processed, for example, temperature controlled, in the at least one rinse tank while the wash step continues in the wash chamber. The rinse tank may include, for example, at least one boiler.

[0072] As described above, the cleaning system also has at least one suction device configured to be connected to the suction element of the cleaning basket and to generate negative pressure. The suction device may be integrated into the cleaning basket wholly or partially. Alternatively, or additionally, the suction device may be integrated into the cleaning device wholly or partially.

[0073] As used herein, the term "suction device" is a broad term to which the customary and general meaning understood by those skilled in the art is attributed. This term is not limited to any specific or adopted meaning. This term may relate, without limitation, to any desired device configured, particularly in the form of, to draw at least one fluid, particularly a liquid, from a target space. The suction device may particularly have at least one pump and / or at least one vacuum source. The suction device may be wholly, partially, or fixedly integrated into the cleaning device, or may have a vacuum connection of the cleaning device, for example, to which the cleaning device is connected to a vacuum line, for example, a field vacuum line. However, alternatively or additionally, the cleaning device may have at least one negative pressure source, particularly at least one pump, which is also referred to as a vacuum source. The suction device may be fixedly connected to or disengaged from the suction element of the cleaning basket. Again, alternatively or additionally, the suction device may be wholly or partially integrated into the cleaning basket, for example, in the form of at least one venturi nozzle.

[0074] The cleaning system may also have at least one pressurizing device having at least one pressure connection. The pressurizing device can generally be understood to mean a device configured to provide a fluid, particularly a gas, at a pressure above normal pressure, for example, at least 1.5 bar, preferably at least 2 bar.

[0075] A pressure connection can, in principle, be understood to mean any desired connection of a pressurizing device through which a fluid, particularly a gas, can be supplied to the pressurizing device. In particular, such a pressure connection may be located inside a cleaning chamber and / or accessible from inside the cleaning chamber. Providing multiple pressure connections may also be considered.

[0076] The pressure connection is configured to be connected to at least one gas delivery element of a breathing device within a flushing chamber, preferably to multiple gas delivery elements of multiple breathing devices within a flushing chamber. A gas delivery element can generally be understood to mean an element that is filled with breathing gas or otherwise comes into contact with breathing gas while a human or animal user is using the breathing device. In particular, this may be a breathing regulator and / or a breathing tube having at least one valve. In particular, the gas delivery element may be at least one tube and / or at least one other type of gas delivery device having an internal space and / or an element having at least one valve to which the flushing fluid should generally not be applied. For example, the gas delivery element may be a gas delivery area of ​​a breathing device that is filled with a pressure above normal pressure during operation, for example, a pressure above normal pressure, for example, a pressure of 1.5 bar or more, particularly a pressure of 2 bar or more. In particular, this may be a breathing gas delivery area of ​​a breathing regulator, where the breathing regulator may, in principle, be a single-stage or multi-stage breathing regulator. Here, the gas delivery element may be, for example, part of the first stage and / or second stage and / or optionally additional stage of a breathing regulator, or it may be the complete breathing regulator. For example, the gas delivery element may be the area between the tube connection and the valve of the breathing regulator, or the gas delivery element may include this area.

[0077] In order for the fluid under the pressure of the pressurizing device to be transferred into the gas delivery element, preferably without fluid loss and / or pressure loss occurring at such connection, the connection between the pressure connection and the gas delivery element can generally be understood to mean a fluid connection, particularly a gas connection. Additionally, in order for the breathing device to be fixedly connected to the pressure connection, the connection between the pressure connection and the gas delivery element of the breathing device may optionally be at least one mechanical connection, particularly a form fit and / or pressure fit connection. For example, this may be a screw connection and / or a clamping connection and / or a tensioning connection, and for this purpose, the pressure connection and / or the breathing device may each have at least one mechanical connection element. In particular, this may be a quick-acting coupling, such as a coupling piece for the breathing connection of a breathing regulator, for example, and / or a threaded plug-in connection. In this case, the quick-acting coupling should generally be understood to mean a gas-tight and / or liquid-tight plug-in connection between two fluid-conducting components, which may be mechanically secured by a mechanical fastener that can be created and released in a simple and rapid manner, for example, by at least one clip and / or bayonet closure and / or screw plug, for example, a union nut, without using screw plugs. The connection may be created particularly without tools. In particular, the pressure connection may include a number of adapters of a fixed or interchangeable design for connecting to various types of gas-conducting elements.By means of these adapters, a number of various gas delivery elements, for example, gas delivery elements of various manufacturers or various kinds and / or types of various manufacturers, may be connected directly or indirectly to the pressure connection. For example, a series of adapters having a number of various coupling pieces (e.g., coupling pieces of a quick-acting coupling) and / or threads may be provided for connecting the various gas delivery elements. For example, these may be various quick-acting coupling systems and / or standard threads. However, alternatively or additionally, at least one pressure connection may also be configured as a fixed pressure connection for a specific type of connection element or a specific type of gas delivery element. It is particularly advantageous if the pressure connection and / or coupling system is configured in such a way that gas cannot escape when the corresponding element is not connected, and in this case, other media, such as cleaning fluid, cannot enter the gas delivery element.

[0078] The pressurizing device is configured to fill the gas delivery element with compressed gas. Compressed gas can generally be understood to mean any desired gas having a pressure greater than a standard pressure, i.e., a pressure of 1 bar or more. This may be a pressure of 1.5 bar or more, particularly 2 bar or more, and particularly preferably 3 bar or more. In particular, the pressurizing device may be configured such that pressurization by the compressed gas occurs in such a way that all cleaning fluid is kept away from the internal space of the breathing device filled with compressed gas. The compressed gas may be, for example, compressed air or some other gaseous medium under positive pressure, such as nitrogen, carbon dioxide, etc. In particular, an inert gas may be used as the compressed gas. The cleaning device may be configured such that pressurization through the pressurizing device occurs during at least one cleaning operation, for example, during at least one program stage of a single-stage or multi-stage cleaning program. In particular, the filling of the compressed gas may be performed simultaneously with the application of the cleaning fluid to the breathing device. Thus, so that the filling of the compressed gas and the application of the cleaning fluid may occur simultaneously, the pressure connection may be placed particularly within the cleaning chamber.

[0079] The pressurizing device, in particular:

[0080] - At least one external pressure connection for connecting to an external compressed gas supply source, in particular to a field compressed gas line and / or a compressed gas cylinder;

[0081] - The cleaning device may have at least one element selected from the group consisting of a compressed gas supply source integrated into the cleaning device, particularly an integrated compressed gas cylinder and / or an integrated compressor.

[0082] As described above, the pressure connection may specifically include at least one form-fit and / or pressurized fit connection element. This connection element may be configured to create a mechanical connection to the breathing device in addition to a hermetic connection. In particular, the at least one connection element may have at least one quick-acting coupling and / or at least one thread. Generally, the pressure connection may be integrated, in particular, wholly or partially into the flushing basket. The flushing basket may generally have at least one releaseable compressed gas connection, in particular to the flushing device. The pressurizing device may specifically have at least one valve, in particular, at least one valve that can be actuated by the controller of the flushing device.

[0083] The wash basket may have at least one connection part, for example, at least one releaseable suction connection part, for connecting a suction element to a suction device. This connection part may be manually connected to the suction device, for example, by a suction connection part having at least one releaseable connection element, for example, a quick-acting coupling, a screw connection part, or a bayonet closure. Alternatively or additionally, the connection may be configured such that the connection of the suction element to the suction device is automatically created, for example, when the wash basket is introduced into the wash chamber of the wash device. Thus, for example, when the wash basket is introduced into the wash chamber, the wash basket may be pressurized against the suction port or suction opening of the wash device by the connection part, for example, the releaseable suction connection part. For example, when the wash chamber is closed by an opening device of the wash device that is pressurized against the wash basket, for example, a door, a pressurized connection may be created between the connection part and the suction port and / or the suction opening of the wash device.

[0084] As described above, the suction device may include at least one vacuum source that can be integrated wholly or partially into the cleaning device, in particular. However, alternatively or additionally, the suction device may have at least one vacuum connection that can be connected to an on-site vacuum source, for example, a vacuum line. In particular, the suction device may include at least one device selected from the group consisting of a jet pump, in particular a venturi nozzle; and a pump. This device may be integrated wholly or partially into the cleaning device and / or cleaning basket, in particular.

[0085] The suction device may be configured to return the cleaning fluid, particularly inhaled from a protective breathing mask, into the fluid system of the cleaning device, particularly into at least one tank of the cleaning device. To this end, the suction device may separate the cleaning fluid from the fluid flow inhaled particularly from the internal space of the protective breathing mask. Thus, the cleaning system, particularly the cleaning device and / or particularly the suction device may have at least one liquid separator.

[0086] The suction device may specifically have at least one valve. Thus, for example, the suction device may operate in an activated form, and thus the suction operation may be performed, for example, only at a specific time. At least one valve may be controlled, for example, by a controller of a cleaning device, and thus the suction operation may be performed, for example, as part of at least one program step of a cleaning program.

[0087] The suction device may have at least one suction line, in particular, which may be connected to a connection part of a washing basket. As described above, this suction line may have at least one suction port and / or suction opening that can be connected, for example, manually and / or automatically, to at least one connection part, for example, a washing basket, in particular to at least one suction connection part of a suction element.

[0088] As described above, the washing device can be configured in various ways. Accordingly, the washing device may be configured as a single-chamber washing device or a multi-chamber washing device. The washing device may be configured as a stationary washing device in which the washing basket is maintained in a fixed manner within the washing chamber during the washing operation, or as a transfer washing device in which the washing basket is transported through the washing chamber. In particular, the washing device may include a single-chamber washing machine, particularly a commercial single-chamber washing machine having at least two tanks. Thus, the single-chamber washing machine may have at least one fluid tank formed separately from the washing chamber, thereby allowing at least one washing fluid to be controlled in the fluid tank independently of the washing process in progress within the washing device, and particularly heated. The single-chamber washing machine may have at least one additional washing tank connected to the washing chamber, for example. However, alternatively, the washing device may be configured as a washing machine, for example referred to as a water-changing washing machine, and may include a single-chamber washing machine having, for example, only one tank and not a separate fluid tank.

[0089] As described above, the washing device may have at least one controller and may be configured to execute at least one washing program in at least two different program stages. As used herein, the term "controller" is a broad term to which the customary and general meaning understood by those skilled in the art is given. This term is not limited to any specific or adopted meaning. This term may, without limitation, relate to a single-component or multi-component unit of the washing device configured to control and / or regulate the operation of the washing device, in particular, in whole or in part. In particular, the controller may be configured to change, in particular, control and / or regulate one or more operating parameters of the washing device, e.g., at least one temperature, at least one pressure, at least one pump output, at least one valve position, at least one heating output, or a combination of two or more of the above operating parameters. The controller may particularly include at least one data processing unit, e.g., at least one processor. The controller may be configured to control or execute at least one washing program of the washing device, e.g., in terms of programming. Thus, the controller installation may be achieved by software, in whole or in part, partially and / or alternatively by hardware or additionally. Additionally, the controller may include at least one volatile and / or non-volatile data memory. Additionally, the controller may include at least one interface, for example, a human / machine interface for command input and / or information output, and / or a wireless or wired interface for unidirectional or bidirectional exchange of data and / or commands between the washing device and at least one additional device. The controller may particularly include at least one computer and / or at least one processor. The controller may particularly be a central or distributed machine controller of the washing device.

[0090] The controller can be configured, in particular, for example, by programming to charge an intake element with negative pressure in at least one program step of the cleaning program so that the penetrating cleaning fluid is drawn at least partially into the intake opening from at least one internal space of the protective breathing mask.

[0091] In an additional embodiment, a method for cleaning a breathing apparatus is proposed. The method includes steps described in more detail below. These steps may be performed in the order described. However, a different order is also possible. Additionally, two or more of the steps of the method described above may overlap in time or be performed simultaneously. Additionally, one or more of the steps of the method described above may be performed once or repeatedly. In addition to the steps described above, the method may include additional method steps not described.

[0092] The method includes the following steps:

[0093] a) providing at least one washing basket according to the present invention, for example according to one or more of the configurations described above and / or according to one or more of the embodiments described below;

[0094] b) a step of securing at least one protective breathing mask of the breathing device to at least one mask holder of the washing basket;

[0095] c) a step of introducing an inhalation element into at least one internal space of a protective breathing mask in such a manner that at least a portion of the inhalation element, having at least one inhalation opening, protrudes into the internal space;

[0096] d) a step of applying at least one cleaning solution to the breathing device; and

[0097] e) A step of filling the suction element with negative pressure and sucking the cleaning solution from the internal space through the suction opening.

[0098] The method may be performed in such a manner that a cleaning system according to the present invention, for example, according to one or more of the configurations described above and / or according to one or more of the embodiments described below, is used. Accordingly, the application in step d) of the method may be performed in the cleaning chamber of the cleaning device. The filling in step e) may be performed by the cleaning device or in a manner controlled by the cleaning device. For possible configurations, refer to the description of the cleaning system above.

[0099] As described above, the suction of method step e) may be performed wholly or partially while at least one cleaning solution is applied to the breathing device in step d), or may be moved downstream wholly or partially in terms of time in method step d). In particular, method step e) may be performed at least partially after method step d). This downstream movement in terms of time may occur in such a way that the suction is initiated by moving downstream over time while the cleaning basket is stationary. Alternatively, when the cleaning basket moves, for example in the case of a transfer cleaning device, the downstream movement may be performed spatially, for example, by first applying at least one cleaning solution in at least one area and then suctioning in at least one area.

[0100] The method may include the following additional steps:

[0101] f) A step of filling at least one gas delivery element of the breathing device with compressed gas.

[0102] Method step f) may be performed temporarily, particularly simultaneously with one or both of method steps d) and e). In particular, method step f) may be performed in an overlapping manner with one or both of the method steps in terms of time. In particular, the filling of compressed gas may be performed simultaneously when the cleaning solution is applied to the breathing device.

[0103] The method may include the following additional steps:

[0104] g) At least one drying step in which the breathing device is dried.

[0105] The drying step may be performed inside or outside the washing chamber. For example, the drying step may be performed by transferring the article to be washed from the washing chamber into a drying device, for example, a drying cabinet. The drying step may include, for example, a heating step of a breathing device, for example, a drying step using hot air. Other drying methods are also known, for example, dishwasher technology, for example, condensation drying. Method step e), that is, the step of charging the suction element with negative pressure and suctioning the washing liquid, may be performed at least temporarily before the drying step is performed, or wholly or partially during the drying step. Generally, the drying step performed wholly or partially after suction may be performed more efficiently than the described suction step.

[0106] The proposed cleaning basket, the proposed cleaning system, and the proposed method for cleaning the proposed breathing device have many advantages over the conventional devices and methods of the above-mentioned type. Accordingly, the technical problems of the known devices and methods of the above-mentioned type, in particular, can be solved.

[0107] The suction element may be configured as a particularly flexible, movable suction member and / or suction pipe. The suction element may be used to suction out residues of the cleaning solution, particularly residues of liquid detergent, remaining in the draining volume of the protective breathing mask after washing, for example, in a part of the internal space. The suction element may be charged with negative pressure, for example, by an internal or external suction device. Thus, negative pressure may be provided or generated using an external pressure line or pressure line already present in the cleaning device, for example, a washing machine. For example, a compressed air line may be used to supply compressed air. The negative pressure for suctioning out liquid residues may be generated, for example, by at least one jet pump, particularly a venturi nozzle.

[0108] Additionally, the cleaning solution can be separated after inhalation. For example, the cleaning system can be configured to switch and / or separate the cleaning solution / air mixture, particularly the water / air mixture. In particular, the inhalation device can be configured to deliver the cleaning solution / air mixture from the outlet of the inhalation device to the bottom of the cleaning chamber in a manner shielded specifically by the actual cleaning chamber. Thus, the breathing device can be prevented from becoming wet again with the cleaning solution, particularly residual liquid.

[0109] The internal space of the protective breathing mask may specifically be a drainage space, or may have at least one drainage space. In washing and dishwasher technologies, the drainage space generally relates to the geometry of the item to be washed, where liquid detergent cannot be automatically drained. In the case of a protective breathing mask, the drainage space is generally formed between the mask wall and the surrounding sealing lip, which serves to seal the protective breathing mask against the user's face. Alternatively or additionally, the drainage space may be formed in an extension at the bottom of the protective breathing mask, to which a filter and / or breathing device is typically connected. The remaining washing liquid can be completely or partially removed from the at least one drainage space by the proposed suction element. This avoids the aforementioned disadvantages of conventional washing devices. In particular, the drying process can be accelerated, the washing results improved, and the leakage of washing liquid to the floor of the work area can be at least substantially prevented.

[0110] The suction element can be adjusted for each intended purpose in terms of its geometric structure and / or configuration. Accordingly, the suction element may have at least one connection for negative pressure, and, for example, at least one suction opening through which residual liquid can be sucked in. The suction element may be designed in such a way that the suction opening can be easily introduced, particularly at the lowest point or at least near the lowest point of the drainage space. Additionally, the suction element may be configured to support the securing of a protective breathing mask to a mask holder within a washing basket.

[0111] The suction element can be flexibly mounted, particularly in terms of spatial orientation and / or position within the wash basket. For example, various orientations and / or shapes of the suction element may be possible. For instance, mobility in different directions, such as all three spatial directions, and alternatively or additionally optionally, a spring suspension in the wash basket may further support these requirements.

[0112] One or more mask holders may be provided in the washing basket. If multiple mask holders are provided, each mask holder may be placed, for example, in at least one suction element. If multiple suction elements are provided in the washing basket, they may be connected to a common suction line, for example, a common channel. The suction line may be connected to a suction device. The suction line may be connected to a suction pump, for example, a suction port of a venturi nozzle, and thus may be filled with negative pressure. As described above, the suction device may also be integrated wholly or partially into the washing basket itself, so that, for example, the washing device provides only pressure, such as compressed air, for the operation of the suction device, for example, a venturi nozzle.

[0113] The connection between the suction element of the cleaning basket and the suction device may be fixed or releaseable. For example, one or more tube connections may be provided that can be configured to be easily released by, for instance, one or more quick-acting couplings. Various materials for the channels and connections, such as plastics, stainless steel, elastomers, or combinations of the aforementioned materials and / or other materials, may also be considered. The materials used must generally meet the requirements during the cleaning operation, particularly with respect to thermal and / or chemical stability.

[0114] Generally, the charging of negative pressure by a suction device can be performed in various ways. Thus, apart from the pump integrated into the cleaning device, the suction action may be generated by other means as an alternative or additional means. Accordingly, the suction device may have at least one water jet pump that can be operated, for example, with fresh water, for example, from an on-site supply source. Again, as an alternative or additionally, as described above, a connection to an on-site negative pressure supply device, or an alternative or additional connection to a suction device operated by an electric motor, is possible.

[0115] The suction device may be controlled, for example, through at least one valve, for example, through at least one solenoid valve. The valve may be controlled, in particular, by at least one controller of the washing device, specifically, for example, by at least one machine controller according to the washing program. Optionally, as described above, the compressed air supply device may be additionally switched on. Depending on the requirements, for example, to improve washing and rinsing results, residual liquid may be sucked from the drainage space between individual program stages.

[0116] The suction device may be operated according to requirements, for example, by a corresponding washing basket that operates the facility with the help of identifying the basket present in the washing device. Accordingly, the washing device may have at least one identification device, such as at least one sensor, which can be configured to identify the type of washing basket and, in particular, whether the washing basket has at least one suction element or is a washing basket without a suction element. Accordingly, the controller may be configured to operate or not operate the suction device.

[0117] The cleaning device may also have one or more compressed air nozzles to spray compressed air and / or compressed gas onto the breathing device. For example, the cleaning device may have one or more flexible and / or movable compressed air nozzles, thereby allowing compressed air and / or compressed gas to be delivered in a specific manner onto at least one protective breathing mask, particularly to aid in the drainage of cleaning fluid and improve drying results. In this way, residue of cleaning fluid may be prevented or at least reduced, for example, in one or more observation windows of the protective breathing mask, particularly in areas related to visibility. One or more compressed air nozzles may be provided with at least one dedicated switching element, such as at least one valve, which can be operated by a controller.

[0118] Overall, the amount of residual liquid in the drainage space of a protective breathing mask can be reduced, for example, by the proposed suction element and the proposed suction device. This eliminates the need to shake it out by hand after washing, for example. In particular, the drainage space can be suctioned at the end of a program sequence or before the end of a program sequence, for example, after the cleaning solution is applied. The cleaning solution can also be suctioned between two program steps, for example, between two program steps where various types of cleaning solutions are applied to the breathing device. For example, to completely or partially remove the cleaning solution from the internal space, particularly the drainage space, before the rinsing step, the suction step can be connected between the washing step and the rinsing step. The rinsing results can be further improved, particularly in this manner.

[0119] In addition, drying time may be significantly improved both during drying inside the washing chamber and during drying outside the washing chamber, for example, in a drying cabinet. Thus, for example, by at least one suction element and / or at least one suction device, the residual amount of washing solution within the protective breathing mask can be reduced compared to conventional methods. Consequently, the drying time required, for example, inside the washing device itself and / or inside the drying cabinet, is shortened.

[0120] In addition, the rinsing results may be further improved by at least one of the aforementioned compressed air nozzles. If additional compressed air nozzles are used, the use of rinse can be minimized and drying time reduced, while at the same time, residue-free drying can be achieved at critical points, such as observation windows.

[0175] Additional details and features are derived from the following description of exemplary embodiments, particularly in relation to dependent claims. Herein, each feature may be embodied in itself or combined with one another in various ways. The invention is not limited to exemplary embodiments. Exemplary embodiments are schematically illustrated in the drawings. In each drawing, the same reference numeral indicates identical or functionally identical elements that correspond to one another in terms of their function. Specifically: FIG. 1 illustrates an exemplary embodiment of a cleaning system for cleaning a breathing device in a cross-sectional view from the side; FIG. 2 shows an oblique perspective view from above of an exemplary embodiment of a washing basket; FIG. 3 shows a top view of a washing basket according to FIG. 2; FIG. 4 shows a detailed perspective view of a mask holder of a washing basket according to FIG. 2 without a protective breathing mask; and Figure 5 shows a partial perspective cross-sectional view of a mask holder with a protective breathing mask spread out on top. Specific details for implementing the invention

[0176] FIG. 1 illustrates an exemplary embodiment of a cleaning system (110) for cleaning a breathing device (112) in a cross-sectional view from the side. The breathing device further includes at least one protective breathing mask (114) and optionally additional components such as, for example, a gas delivery element (116), for example, a breathing regulator.

[0177] In this exemplary embodiment, the washing system (110) includes a washing device (118) and at least one washing basket (120). The washing basket (120) is schematically illustrated in FIG. 1. Detailed views of possible configurations of the washing basket (120) are illustrated in FIG. 2 through 5. FIG. 2 shows an oblique perspective view of the washing basket (120) from above, FIG. 3 shows a top view of the washing basket (120), FIG. 4 shows a detailed perspective view of a mask holder (122) without a protective breathing mask (114), and FIG. 5 shows a partial perspective cross-sectional view of the mask holder (122) with the protective breathing mask (114) spread over it. These drawings are described below.

[0178] The washing device (118) has a housing (124) in which various components of the washing device (118) are accommodated. For example, a controller (126) of the washing device (118) may also be accommodated in the housing (124). The housing (124) surrounds a washing chamber (128) for accommodating at least one washing basket (120). The housing (124) may have, for example, an opening device (130) so that the washing chamber (128) can be opened and closed to introduce the washing basket (120) into the washing chamber (128). In the illustrated exemplary embodiment, the opening device (130) is illustrated as a hood (132). Thus, the washing device (118) may be configured, for example, as a pass-through washing machine. However, other configurations are also possible, for example, in which the opening device (130) is designed as a cover or a door. The washing chamber (128) is illustrated in an open state in FIG. 1. For example, a basket receptacle (134), for example, a rail system may be provided in the washing chamber (128).

[0179] The cleaning device (118) includes at least one application device (136) for applying at least one cleaning solution to the breathing device (112). Regarding possible configurations of the application device (136), reference may be made to the aforementioned prior art, for example, WO 2011 / 144518 A2. In particular, the application device (136) may have at least one nozzle system (138). Additionally, the application device (136) may have at least one, preferably at least two, tanks for receiving at least one cleaning solution, and one or more pumps.

[0180] For example, as can be seen in FIG. 2, the washing basket (120) of the illustrated exemplary embodiment includes a basket shelf (140) having a basket wall (142) and a basket bottom (144). The washing basket (120) also includes at least one mask holder (122) as previously mentioned, and in the illustrated exemplary embodiment, four mask holders (122) are provided as an example. The mask holders may be oriented, for example, such that a protective breathing mask spread over each of them faces the four corners of the washing basket (120). Other numbers are also possible. In the illustrated exemplary embodiment, the mask holders (122) are connected to the basket shelf (140) in a fixed or releaseable manner, and may be releasedable on the basket shelf (140) as a shelf, for example.

[0181] As can be seen in the drawing, the mask holder (122) may be designed as a wire loop, for example, made of a round wire. However, other embodiments are also possible in principle, and for example, an embodiment in which the mask holder (122) has a head shape or a face shape is also possible.

[0182] For example, as can be seen in FIG. 5, at least one protective breathing mask (114) may be placed or unfolded on a mask holder (122). This may preferably be done in such a way that at least one observation window (146) of the protective breathing mask (114) faces upward. Conversely, at least one internal space (148) of the protective breathing mask (114) is generally formed at the bottom, and said internal space (148) is partially surrounded by the protective breathing mask (114) and is generally open downward in an unfolded state. Nevertheless, one or more drainage spaces (150) are generally formed in said internal space (148), for example in the area of ​​one or more seals (152) and / or in the connection area (154) for at least one gas delivery element (116). Since the protective breathing mask (114) is typically washed up and down and the cleaning solution is applied, for example in the case of the configuration according to FIG. 1, the cleaning solution accumulates in this internal space (148) in principle as described above, and the cleaning solution cannot be completely removed after the application of the cleaning solution is finished. In many cases, the residual amount of this cleaning solution interferes with the washing and subsequent drying operations within the washing device (118) and / or in a separate drying cabinet, and furthermore, if it leaks onto the floor in front of the washing device (118), it can cause safety problems due to the risk of slipping.

[0183] To prevent such problems, the cleaning basket (120) also has at least one suction element (156). The suction element (156) is configured, for example, as a pipe, tube, or channel, or preferably configured such that a lumen (157) is formed therein, thereby allowing the suction element (156) to be filled with vacuum or negative pressure. For example, in this embodiment and also in other exemplary embodiments, the suction element (156) may be designed as a curved pipe loop (158) or may include a pipe loop (158), wherein preferably the pipe loop (158) or its curved portion faces downward.

[0184] The suction element (156) includes, for example, at least one suction opening (160) formed at the lowest point of the pipe loop (158). For example, as can be seen in FIG. 5, the suction element (156) is configured in such a way that it can extend into the internal space (148) of the protective breathing mask (114) held by the mask holder (122). For example, in each case, at least one suction element (156) may be placed in each case of the mask holder (122). The suction element (156) is configured to be filled with negative pressure, for example, by applying a corresponding vacuum or negative pressure to the lumen (157). In this way, the cleaning fluid may be sucked from the internal space (148) into the suction opening (160) to completely or partially remove the cleaning fluid from the internal space (148), particularly the drainage space (150).

[0185] To facilitate the introduction of the suction element (156) into the internal space (148), the suction element (156) may be configured to be particularly flexible, especially elastic, at least partially. For example, as can be seen in FIG. 4, for this purpose, the suction element (156) may be mounted elastically, for example. As illustrated as an example in the drawing, the suction element (156) may extend directly or indirectly from, for example, the mask holder (122), where the extent of the extension may be variably configured, for example, by a spring bearing (162). In this way, for example, the illustrated pipe loop (158) may be configured as a flexible tongue. Additionally, due to this flexibility, it may be ensured that, for example, the suction opening (160) is positioned near the lowest point of the drainage space (150).

[0186] The washing basket (120) also has at least one suction line (164), and a suction element (156) is fluidly connected to the suction line (164) in such a way that the suction element (156) can be charged with negative pressure through the suction line (164). The suction line (164) can provide a common or separate negative pressure charge for the suction elements (156) when a plurality of suction elements (156) are provided in the washing basket (120). The suction line (164) can be designed to be rigid or flexible.

[0187] The suction line (164) may have at least one connection (166) for connecting at least one suction element (156) to a negative pressure source. In particular, the connection (166) may allow a connection to the suction device (168) illustrated as an example in FIG. 1, preferably a detachable connection. In such a connection, there are multiple possibilities for joining together. Thus, the suction device (168) may be fully integrated into the cleaning device (118), for example, as illustrated in FIG. 1. However, alternatively or additionally, the suction device (168) may also rely wholly or partially on a field device, for example, a vacuum line. Again alternatively or additionally, the suction device (168) may also be wholly or partially integrated into the cleaning basket (120).

[0188] In particular, as illustrated in FIG. 1, the suction device (168) may have a pump (170). This pump may be designed, for example, as a jet pump (172) and may include a venturi nozzle (174). For example, the cleaning device may have a compressed gas line (176) connected to the venturi nozzle (174), for example, through a valve (178). The venturi nozzle (174) is a part that is connected to or may be connected to the connection (166) of the cleaning basket (120), for example, through the suction line (180). This connection may be made automatically or manually, for example, when the cleaning basket (120) is introduced into the cleaning chamber (128). For example, an automatic connection may be made when the opening device (130) is closed. Additionally, one or more valves, for example, at least one backflow prevention valve (182), may be introduced into the suction line (180). Instead of the illustrated jet pump (172), other types of suction devices (168), such as other types of vacuum pumps or liquid pumps, may be used as alternatives or additionally.

[0189] Additionally, the suction device (168) may have at least one liquid separator (184), similarly illustrated as an example in FIG. 1. The liquid separator may be connected, for example, to a venturi nozzle (174) and / or another type of jet pump (172). The liquid separator (184) may be configured such that the separated cleaning fluid sucked from, for example, the internal space (148) is returned into the fluid system of the cleaning device (118). For example, the liquid separator (184) may be placed wholly or partially within or connected to the cleaning chamber (128). For example, the separated cleaning fluid may be returned directly or indirectly into the tank of the cleaning device (118).

[0190] For additional components of the washing basket (120), reference may be made to WO 2011 / 144518 A2, for example. In particular, to accommodate small parts, the washing basket (120) may have at least one small parts basket, for example, in which accessories can be placed on the protective breathing mask (114) and washed without being lost.

[0191] Additionally, the suction described herein may be combined with the pressurization principle of the gas delivery element (116) described in WO 2011 / 144518 A2 while the cleaning fluid is applied to the breathing device (112) to prevent the cleaning fluid from penetrating the gas delivery element (116). As can be seen in FIG. 1, this principle may be based on the same compressed gas line (176) as the suction. However, separate pressurization is also possible.

[0192] To realize the above pressurization for the gas delivery element (116), the washing basket (120) may further have at least one pressure connection (188), as seen, for example, in FIGS. 1, FIGS. 3 and FIGS. 5. The pressure connection (188) is configured to fill the gas delivery element (116) with compressed gas while the washing liquid is applied to the breathing device (112). To this end, the pressure connection (188) may have, for example, at least one quick-acting coupling (190). The pressure connection (188) may be connected to the pressurizing device (194) of the washing device (118), for example, through a releaseable compressed gas connection (192). This connection may again be created manually or, for example, automatically when the opening device (130) is closed. The pressurizing device (194) may include a compressed gas supply source integrated, for example, into a cleaning device (118), or may rely on an external compressed gas supply source, for example, an on-site compressed gas supply device (196), as illustrated as an example in FIG. 1. The on-site compressed gas supply device (196) may optionally be used simultaneously, for example, by a branch (198), for the operation of the suction device (168). The pressurizing device (194) may include a compressed gas line (200) that may be connected, for example, to a compressed gas connection (192). Optionally, at least one backflow prevention valve (202) may be provided in the compressed gas line (200).

[0193] The pressurizing device (194) may also be additionally used to spray compressed gas, e.g., compressed air, into the breathing device (112) by means of one or more nozzles, e.g., not shown in FIG. 1. This is used during drying, e.g., to further facilitate the drainage of the cleaning fluid from the breathing device (112), particularly the protective breathing mask (114).

[0194] The washing device (118) may be configured as an automatic programmed washing machine, in particular, and may be configured by a controller (126) to perform at least one washing program in a number of program steps. For example, a washing liquid may be applied in at least one program step, and for example, said at least one program step may include at least one washing step and at least one rinsing step. During the step of applying the washing liquid, the above-mentioned pressurization of at least one gas delivery element (116) may be performed. Suction may be performed during this application or in a subsequent program step. This may be performed, for example, in a separate suction step. This step may also be wholly or partially integrated into a drying operation that may be performed wholly or partially in the washing device (118) as described above.
