Description

[0001] The invention relates to a sanitary cabin, in particular a toilet cubicle, with at least one floor part, at least one ceiling part and a plurality of side wall parts, wherein at least one waste tank is also provided, wherein at least one sanitary facility, in particular at least one urinal and / or at least one hand wash basin, is arranged in the sanitary cabin. Furthermore, the invention relates to a method for the operation and for the maintenance or cleaning of a sanitary cabin, in particular a toilet cubicle. It is recommended that the sanitary cabin according to the invention is a mobile or transportable sanitary cabin. Such mobile sanitary cabins can be transported in particular on transport vehicles. They can be used flexibly in places where there are no permanently installed sanitary facilities. The mobile sanitary cabins are therefore usually set up for specific periods of time, for example on construction sites or at events such as markets, trade fairs, festivals and the like. The mobile or transportable sanitary cabins are then removed and finally cleaned.

[0002] Sanitary cabins of the type described previously are basically known from practice in different embodiments. The waste water from the sanitary facilities of these sanitary cabins is usually collected together with the waste water and the feces from a toilet bowl in the waste tank of the sanitary cabins. The sanitary cabins set up at the site are intermediately cleaned at certain intervals. As a rule, the waste tank is first emptied and the contents of the waste tank are pumped out and collected, particularly by a service vehicle. A liquid supply, particularly based on fresh water, is then filled into the waste tank. Usually, about 10 to 30 L of fresh water are poured into the waste tank so that preferably the bottom of the waste tank is covered by the liquid supply. Colorants and / or odorants are preferably added to the liquid supply. The sanitary cabin is then ready for use again and can continue to be used at the site.

[0003] However, these measures, which are known from practice, are characterised by the disadvantage that in the course of the maintenance or cleaning process, a relatively large amount of faeces and waste water must be removed from the waste tank, in particular pumped out and taken up by the service vehicle, and in addition, a sufficient amount of fresh water must be provided for the liquid supply of each sanitary cabin that is cleaned intermediately, in particular carried along by the service vehicle. This is where the invention comes in.

[0004] In view of this, the invention is based on the technical problem of providing a sanitary cabin, in particular a toilet cubicle, of the type mentioned initially, in which the disadvantages described above can be effectively and reliably avoided and in which, in particular, the maintenance and cleaning costs can be reduced in relation to the amount of faeces and waste water to be removed from the waste tank, in particular to be pumped out, and preferably also in relation to the amount of fresh water required for the liquid supply of the waste tank. Furthermore, the invention is based on the technical problem of providing a corresponding method for operation and maintenance or cleaning of a sanitary cabin.

[0005] To solve the technical problem, the invention teaches a sanitary cabin, in particular a toilet cubicle, comprising at least one floor part, at least one ceiling part and a plurality of side wall parts, wherein at least one waste tank is also present, wherein at least one sanitary facility, in particular at least one urinal and / or at least one hand wash basin, is arranged in the sanitary cabin, wherein the sanitary cabin also has at least one collecting tank in which the waste water from the at least one sanitary facility, in particular the waste water from the at least one urinal and / or the at least one hand wash basin, can be collected, and wherein the waste water collected in the collecting tank in the course of maintenance or cleaning of the sanitary cabin can be transferred as a liquid supply into the waste tank.

[0006] In the context of the invention, liquid supply means in particular a liquid or amount of liquid, particularly water or water-based liquid, which is poured into the waste tank and thus provided during maintenance or cleaning of the sanitary cabin, preferably after emptying the waste tank. According to the invention, the waste water of the at least one sanitary facility is collected in the at least one collecting tank of the sanitary cabin and the collected waste water can then be transferred to the waste tank as a liquid supply. Expediently, the liquid supply is then waste water. The waste water is treated according to a preferred embodiment. This is explained in more detail below. When reference is made here and subsequently to the waste water of the at least one sanitary facility, this means in particular urine from the urinal and / or liquid used in the course of using the at least one sanitary facility, for example flushing liquid from the urinal and / or liquid used in the hand wash basin.

[0007] Here and subsequently, particular reference is made to the vertical installation state of the sanitary cabin according to the invention, in which the floor part is arranged on a mounting surface and in which the ceiling part is located above the floor part. It has already been pointed out at the beginning that the sanitary cabin according to the invention, according to a preferred embodiment, is a mobile or transportable sanitary cabin, in particular a toilet cubicle. Thus, the sanitary cabin according to the invention is expediently configured to be relatively compact and in this context it is within the scope of the invention that the volume of the interior of the sanitary cabin is only 1 to 7 m3, preferably 1.25 to 3.5 m3 and particularly preferably 1.25 to 3 m3. It is preferred that the sanitary cabin according to the invention is rectangular, in particular square, in plan view. In principle, however, other geometries with regard to the plan view of the sanitary cabin are also within the scope of the invention.

[0008] According to one embodiment of the invention, the sanitary cabin has a plurality of support posts, wherein the floor part is connected to the ceiling part and / or wherein at least two side wall parts are connected to one another via at least one support post. Preferably, the sanitary cabin has at least three, preferably four, support posts. A preferred embodiment of the invention is characterized in that at least some of the support posts are configured as corner posts. According to a further preferred embodiment of the invention, all the support posts of the sanitary cabin are configured as corner posts and preferably the sanitary cabin has four support posts, in particular four corner posts. It is recommended that the sanitary cabin has a ceiling part, a floor part and four support posts configured as corner posts, wherein the corner posts connect the ceiling part to the floor part. In principle, however, other configurations of the sanitary cabin with regard to the connection of the floor part, ceiling part and side wall parts are also within the scope of the invention.

[0009] It is possible within the scope of the invention that a tongue- and groove-connection is realized between a support post, in particular a corner post, and the ceiling part and / or the floor part. Preferably, a side wall part of the sanitary cabin also connects two support posts, in particular corner posts, to each other. To realize this connection, it is within the scope of the invention that tongue-and-groove connections are set up between the side wall part and the two support posts, in particular corner posts. It is recommended that a side wall part of the sanitary cabin is formed by a cabin door, wherein preferably at least one door handle and / or at least one locking element is arranged on the cabin door.

[0010] A highly recommended embodiment of the invention is characterized in that the sanitary cabin has at least one toilet bowl, wherein the toilet bowl is preferably arranged above the waste tank and wherein the waste and / or the waste water from the toilet bowl are preferably collected directly in the waste tank. According to this preferred embodiment, the sanitary cabin thus has a toilet bowl in addition to the at least one sanitary facility, in particular in addition to the at least one urinal and / or the at least one hand wash basin. In this embodiment, the faeces and / or the waste water from the toilet bowl are in particular not collected in the collecting tank according to the invention, but are collected directly or immediately in the waste tank. According to a preferred embodiment, the toilet bowl can have a toilet seat arranged at or on the toilet bowl and / or a toilet lid, which preferably closes the toilet bowl.

[0011] The invention has recognized that by collecting the waste water of at least one sanitary facility in the collecting tank and due to the transferability of the collected waste water in the course of maintenance or cleaning of the sanitary cabin as a liquid supply to the waste tank, both the amount of faeces and waste water to be removed from the waste tank in the course of cleaning, in particular to be pumped out, can be reduced and the amount of fresh water to be made available, in particular to be carried by a service vehicle, for the liquid supply of the waste tank can be at least significantly reduced.

[0012] According to a particularly recommended embodiment of the invention, the at least one collecting tank is arranged or accommodated at least in sections, preferably completely or substantially completely, within the waste tank. It is particularly preferred that the at least one collecting tank is arranged or accommodated completely or substantially completely within the waste tank. This particularly preferred embodiment is a tank-in-tank design. Expediently, the at least one collecting tank is configured with regard to its dimensions in such a manner that it can be inserted into the waste tank through an opening of a toilet bowl arranged above the waste tank. Furthermore, the at least one collecting tank is preferably designed in terms of its dimensions such that it can be accommodated in the waste tank of the sanitary cabin without the capacity of the waste tank being significantly impaired.

[0013] It is further preferred that the sanitary cabin has one, in particular only one, collecting tank. In principle, at least two, in particular two collecting tanks can be arranged in the sanitary cabin. The collecting tank according to the invention preferably forms a collection space separate from the waste tank and is configured in particular as a separate tank container. However, it is also within the scope of the invention that the at least one collecting tank is configured as a section separated from the waste tank, wherein at least one partition wall is then preferably used to separate the collecting tank from the waste tank. The embodiment according to which the at least one collecting tank is arranged or accommodated at least in sections, preferably completely or substantially completely, within the waste tank is based on the finding that with such an embodiment, the transferability of the waste water collected in the collecting tank into the waste tank can be implemented in a particularly functionally reliable manner and that, in addition, no additional space available to the user in the interior of the sanitary cabin is taken up by the at least one collecting tank.

[0014] According to a further embodiment of the invention, the at least one collecting tank is arranged at least partially, preferably completely or substantially completely, outside the waste tank and is preferably arranged below the at least one sanitary facility, in particular below the urinal and / or below the hand wash basin. This embodiment is based on the finding that the waste water of the at least one sanitary facility can then be collected in the at least one collecting tank in a particularly functionally reliable manner and that, in addition, an otherwise unused area below the at least one sanitary facility is used for the at least one collecting tank. In principle, the at least one collecting tank can also be arranged in sections outside and in sections inside the waste tank.

[0015] According to a particularly preferred embodiment of the invention, the collecting tank has at least one drain opening through which the waste water collected in the collecting tank can be transferred to the waste tank. The fact that the collected waste water can be transferred through the drain opening into the waste tank means, in the context of the invention, in particular that the collected waste water passes through the drain opening in the course of the transfer. It is possible within the scope of the invention that the transferability of the collected waste water from the collecting tank into the waste tank is realized by emptying the at least one collecting tank, in particular by transferring the waste water collected in the collecting tank into the waste tank. This can be carried out, for example, by service personnel in the course of maintenance or cleaning of the sanitary cabin. If, according to a preferred embodiment of the invention, the collecting tank is arranged or accommodated at least in sections, preferably completely or substantially completely, within the waste tank, it is also within the scope of the invention that the at least one collecting tank is mounted in the waste tank so that it can be tilted or rotated and that the transferability of the collected waste water into the waste tank can be achieved by tilting or rotating the at least one collecting tank about the bearing axis. Then the at least one collecting tank preferably has a drain opening on the top of the collecting tank and can in particular be configured as a hollow cylinder open on one side, for example as a bucket or pail. In this embodiment, the tiltability or the rotatability of the collecting tank is then expediently set up about a bearing axis arranged transversely, in particular perpendicularly or substantially perpendicularly to the longitudinal extension of the collecting tank.

[0016] According to a particularly preferred embodiment of the sanitary cabin according to the invention, the collecting tank has at least one drain opening through which the waste water collected in the collecting tank can be transferred to the waste tank, and wherein the drain opening and / or a connection or fluid connection between the drain opening and the waste tank is preferably blocked or can be blocked by a blocking element during operation of the sanitary cabin and can be released during maintenance or cleaning of the sanitary cabin. In the context of the invention, operation of the sanitary cabin means in particular the operating state of the cabin sanitary in which no maintenance or cleaning takes place and in which the sanitary cabin can be used by a user. In the context of the invention, drain opening means an opening in the collecting tank through which the waste water collected in the collecting tank passes during its transfer to the waste tank. According to one embodiment, a connection or a fluid connection can be established between the drain opening and the waste tank. This can be achieved, for example, by means of a line connected to the drain opening and / or a follow-up device connected to the drain opening. According to a preferred embodiment of the invention, the drain opening itself and / or the connection or the fluid connection between the drain opening and the waste tank is blocked or can be blocked by a blocking element during operation of the sanitary cabin and can be released during maintenance or cleaning of the sanitary cabin. As a result of the releasability of the drain opening and / or the connection or the fluid connection between the drain opening and the waste tank, the waste water collected in the collecting tank can be transferred to the waste tank in the course of maintenance or cleaning of the sanitary cabin.

[0017] It has proven particularly useful that the blocking element is a closure element, in particular a closure plug, for the drain opening, wherein the drain opening and / or the connection or fluid connection between the drain opening and the waste tank can be released by manipulation of the closure element, in particular by removing the closure plug. The blocking element, which is preferably a closure element, is expediently manipulated in the course of the maintenance or cleaning process in such a manner that the drain opening and / or the connection or fluid connection between the drain opening and the waste tank is released so that the waste water collected in the collecting tank can flow into the waste tank. According to a preferred embodiment, the closure element is a closure plug and the drain opening and / or the connection or fluid connection between the drain opening and the waste tank can preferably be released by removing the closure plug. It is also possible that the closure element is a valve, in particular a ball valve, and that the drain opening and / or the connection or fluid connection between the drain opening and the waste tank can then be released by opening the valve, in particular the ball valve. According to a further preferred embodiment, the closure element is a closing slide valve and, expediently, the drain opening and / or the connection or fluid connection between the drain opening and the waste tank can then be released by actuating the closing slide valve.

[0018] According to a quite particularly preferred embodiment, the at least one collecting tank has a drain opening with at least one blocking element, in particular with a closure element, for example with a closure plug, wherein the drain opening is expediently arranged in a lower collecting tank section—associated with the floor of the sanitary cabin—and in addition an access opening is preferably provided in an upper collecting tank section and preferably accessible from the outside of the waste tank on the inside of the cabin. The access opening is preferably closed by a cover element. By opening the cover element, it is possible for service personnel to open the collecting tank from the outside of the waste tank inside the cabin and, if necessary, add liquids or additives, such as a treatment agent, to the collecting tank. In this embodiment, it is quite particularly preferred that the cover element of the access opening is connected to the closure element of the drain opening of the collecting tank. For example, a chain connection and / or a rope connection and / or a push rod connection may be provided for this purpose. Then it is preferably possible that the closure element of the drain opening is manipulated by manipulating the connection, in particular pulling on the connection, for example the chain connection and / or the rope connection, so that the drain opening of the collecting tank can be opened. If the blocking element is configured as a closure plug according to a preferred embodiment, it is also within the scope of the invention that it is a spring-loaded closure plug. The embodiments in which the blocking element is designed as a closure element are based on the finding that the collecting tank or the drain opening of the collecting tank can be closed simply and reliably by such a closure element and that the releasability of the drain opening and / or the connection or fluid connection between the drain opening and the waste tank for transferring the waste water collected in the collecting tank into the waste tank in the course of maintenance or cleaning of the sanitary cabin can then be carried out very reliably.

[0019] A particularly preferred embodiment of the invention is characterized in that the blocking element is a siphon arrangement downstream of the drain opening, in particular a Bell siphon, and that the drain opening and / or the connection or the fluid connection between the drain opening and the waste tank can be released by manipulating the siphon arrangement, preferably by adding a trigger volume of a liquid into the collecting tank. The fact that the siphon arrangement is arranged downstream of the drain opening means, in the context of the invention, in particular that the siphon arrangement is arranged downstream of the drain opening in the direction of fluid flow and in particular between the drain opening and the waste tank. The trigger volume of a liquid is expediently added to the collecting tank for manipulation of the siphon arrangement in the course of the maintenance or cleaning process. This is preferably a trigger volume of a liquid, for example fresh water, which is introduced into the collecting tank in a sufficiently short time or with a sufficient volume flow in order to manipulate the siphon arrangement in order to release the drain opening and / or a connection or fluid connection between the drain opening and the waste tank and to realize the transferability of the waste water collected in the collecting tank into the waste tank. In this case, the collecting tank is expediently filled up to a certain fill level by the trigger volume and the drain opening or the siphon arrangement is preferably released when this fill level is reached, whereby the transferability of the waste water collected in the collecting tank into the waste tank is achieved by the volume flow of the trigger volume, in particular by suction effect. When the sanitary cabin is in operation, the siphon arrangement then preferably also acts as an overflow device which prevents the collecting tank from overflowing, whereby the transfer of the collected waste water preferably only takes place when a trigger volume is added in a sufficiently short time or with a sufficient volume flow, which is in particular not achieved when the sanitary cabin is in operation. According to one embodiment, the addition of the trigger volume can also be carried out by adding the trigger volume into the at least one sanitary facility, for example into the urinal and / or into the hand wash basin.

[0020] It is also possible within the scope of the invention that the siphon arrangement or a part of the siphon arrangement is configured in such a manner that it is adapted to be height-adjustable in relation to the collecting tank or to the fill level of the collecting tank and that the manipulation of the siphon arrangement or the release of the drain opening and / or the connection or fluid connection between the drain opening and the waste tank is achieved by lowering the siphon arrangement or a part of the siphon arrangement in relation to the collecting tank or to the fill level of the collecting tank. Then the siphon arrangement is preferably configured as a flexibly arranged siphon arrangement, for example as a flexible line. In principle, other types of manipulation of the siphon arrangement are also possible within the scope of the invention, such as changing level of the fill the collecting tank by means of a lifting slider or the like.

[0021] For all the previously described embodiments, it also applies that the at least one collecting tank can be provided with an overflow device which prevents the collecting tank from overflowing during operation of the sanitary cabin if the volume of the collected waste water exceeds or almost exceeds the capacity of the collecting tank or exceeds a certain fill level. It has already been explained previously that the overflow device according to one embodiment can be the siphon arrangement itself. The overflow device can, for example, be an overflow pipe, which is preferably in communication with or in fluid communication with the waste tank. According to one embodiment, the at least one drain opening the of collecting tank is arranged in a lower section of the collecting tank, in particular near the bottom, preferably in the bottom, of the collecting tank. It is possible that the overflow device is configured as an overflow pipe which is arranged in an upper section of the collecting tank, for example near the lid.

[0022] A preferred embodiment of the invention is characterized in that at least one treatment agent for the waste water, in particular at least one chemical and / or biological treatment agent, is present in the collecting tank, wherein the treatment agent is preferably a liquid and / or solid treatment agent and wherein the treatment agent is preferably provided in the collecting tank. According to one embodiment, the treatment agent is a tablet-shaped or powder-shaped treatment agent, which is preferably soluble in the waste water collected in the collecting tank. Within the scope of the invention, the treatment agent serves in particular to improve the waste water quality of the waste water collected in the collecting tank and particularly preferably for disinfection and / or odour improvement. It is particularly preferred that the treatment agent is placed in the collecting tank or the empty collecting tank. However, within the scope of the invention it is also possible that the treatment to agent is added the collecting tank in the course of the maintenance or cleaning process, in particular immediately before the collected waste water is transferred to the waste tank.

[0023] According to a preferred embodiment of the invention, the at least one collecting tank has a capacity of 5 to 35 L, preferably 10 to 30 L, preferably 15 to 25 L. Capacity means in particular to the volume of the collecting tank. The capacity of the collecting tank is suitably dimensioned such that a sufficient quantity of waste water can be collected to provide a liquid supply in the waste tank. Within the scope of the invention, it is possible that only the waste water collected in the collecting tank is transferred to the waste tank as a liquid supply. However, it is also possible that, in addition to the waste water collected in the collecting tank, a certain amount of liquid, for example fresh water, is added to the waste tank, so that the liquid supply of the waste tank is formed by the waste water of the collecting tank and by the additionally added liquid, in particular the fresh water.

[0024] It has proven useful that the sanitary cabin has at least one fresh water reservoir, which can be in communication or in fluid communication with at least one sanitary facility, in particular with the hand wash basin. In principle, the at least one fresh water reservoir can also be in communication or in fluid communication with the urinal. The fresh water can be used in the hand basin by a user to clean his or her hands and / or it can be used as flushing liquid in the urinal. The resulting waste water is then collected in the at least one collecting tank of the sanitary cabin within the scope of the invention. It is possible that at least one support post, in particular at least one corner post, of the sanitary cabin is configured to be partially hollow on the inside and that the at least one fresh water reservoir is arranged in this hollow space. In principle, the fresh water reservoir can also be located at other locations in the sanitary cabin.

[0025] A preferred embodiment of the invention is characterized in that the collecting tank consists or substantially consists of at least one plastic, preferably of at least one thermoplastic material, and wherein the collecting tank is preferably manufactured using a rotational process or by rotational moulding. is The thermoplastic material preferably polyethylene. It is further preferred that the floor part and / or the ceiling part and / or the side wall parts and / or the support posts or corner posts and / or the waste tank and / or the at least one sanitary facility—in particular the at least one urinal and / or the at least one hand wash basin—and / or the toilet bowl consists / consist or substantially consists / consist of at least one plastic, preferably of at least one thermoplastic material. It is further preferred that these components listed above are each manufactured using a rotational process by or rotational moulding. The thermoplastic: material is preferably polyethylene. In principle, however, other materials for the collecting tank or for the components of the sanitary cabin are also within the scope of the invention. The fact that a component of the sanitary cabin consists or substantially consists of plastic means, within the scope of the invention, in particular that additives or supplements may be added. The component then preferably consists of at least 95% by weight, preferably at least 98% by weight, of the at least one plastic or thermoplastic material. It is also within the scope of the invention that the floor part and / or the ceiling part and / or the side wall parts and / or the waste tank and / or the collecting tank and / or the support posts or corner posts and / or at least one sanitary facility are configured as one-piece plastic parts. In principle, individual components of the sanitary cabin can also be manufactured by other manufacturing processes, for example by injection moulding, deep drawing and the like.

[0026] It has proven particularly useful that at least one sanitary facility, in particular the urinal and / or the hand wash basin, is in communication or in fluid communication with the collecting tank, preferably by means of at least one connecting line and wherein the collecting tank preferably has at least one inlet opening for the inlet of the waste water from the at least one sanitary facility into the collecting tank. If, according to a preferred embodiment of the sanitary cabin, at least two sanitary facilities, namely at least one urinal and at least one hand-wash basin, are provided, it is within the scope of the invention that a connection or fluid connection is realized both between the urinal and the collecting tank and between the hand-wash basin and the collecting tank, preferably by means of at least one connecting line. It is then possible that the two connecting lines are brought together in the direction of fluid flow upstream of the at least one collecting tank. The at least one connecting line between the at least one sanitary facility and the at least one collecting tank, in particular the connecting lines between the urinal and the collecting tank and between the hand wash basin and the collecting tank, preferably the combined connecting lines, is / are preferably guided through the at least one inlet opening so that the waste water from the at least one sanitary facility can be let into the collecting tank. It is also possible within the scope of the invention that the two connecting lines are guided separately into the collecting tank, wherein the collecting tank has two separate inlet openings for this purpose according to one embodiment.

[0027] To solve the technical problem, the invention also teaches a method for the operation and for the maintenance or cleaning of a sanitary cabin, in particular of a toilet cubicle-preferably of a sanitary cabin described above—, wherein during operation of the sanitary cabin waste water from at least one sanitary facility, in particular from at least one urinal and / or at least one hand wash basin, is collected in at least one collecting tank of the sanitary cabin, and wherein in the course of maintenance or cleaning of the sanitary cabin, a waste tank of the sanitary cabin is first emptied and wherein the waste water collected in the collecting tank is then transferred to the waste tank as a liquid supply.

[0028] It is within the scope of the method according to the invention that the waste water collected in the collecting tank is treated before and / or after being transferred to the waste tank, in particular by a treatment agent, preferably by a chemical and / or biological treatment agent, and wherein the treatment agent is preferably provided in the collecting tank for this purpose. Additionally or alternatively, it is also possible that the treatment agent is added to the collecting tank immediately before transfer of the waste water collected in the collecting tank. It is therefore particularly preferred that the treatment agent is either placed in the collecting tank or that the treatment agent is added to the collecting tank immediately before transfer of the collected waste water. Additionally or alternatively, it is also possible that the treatment agent is added to the waste tank after the collected waste water has been transferred, so that the waste water is treated after it has been transferred to the waste tank.

[0029] Within the scope of the method according to the invention, it is also preferred that the transfer of the waste water from the collecting tank to the waste tank in the course of maintenance or cleaning of the sanitary cabin is triggered or can be triggered by service personnel. The fact that the transfer is triggered or can be triggered by service personnel means in particular that the service personnel can implement the transfer of the waste water collected in the collecting tank into the waste tank by means of a triggering process in the course of maintenance or cleaning of the sanitary cabin. This can, for example, involve the triggering of a tilting or rotational movement of tiltable or rotatably mounted collecting tank and / or the release of the the drain opening and / or the connection or fluid connection between the drain opening and the waste tank by manipulation of a closure element and / or by manipulation of a siphon arrangement.

[0030] The invention is based on the finding that by means of the sanitary cabin according to the invention, in particular the toilet cubicle, and in particular by means of the collecting tank for waste water from at least one sanitary facility, in particular from at least one urinal and / or at least one hand-wash basin of the sanitary cabin, the amount of faeces and waste water to be removed, in particular pumped out, from the waste tank in the course of maintenance or cleaning of the sanitary cabin can be reduced since the waste water from the at least one sanitary facility is collected in a collecting tank and not in the waste tank. As a result of the transfer, provided according to the invention, of the waste water collected in the collecting tank into the waste tank in the course of maintenance or cleaning of the sanitary cabin as a liquid supply, the necessary amount of fresh water provided for the maintenance or cleaning process and, in particular, which has to be carried by a service vehicle, can at least be significantly reduced. It should be emphasized that these advantages according to the invention are achieved by relatively simple measures, so that the sanitary cabin according to the invention or the method according to the invention for the operation and for the maintenance or cleaning of the the sanitary cabin is very economical.
