DETAILED DESCRIPTION

[0018] In this context, a mobile shower or bathing cabin means that this bathing cabin can be moved from one location to another without being damaged. For example, by means of fully compact transport, i.e. without having to dismantle parts or even the entire shower cabin. Preferably, the shower or bathing cubicle can therefore be loaded onto regular means of transport, such as trailers or cars. For this purpose, a frame of the shower or bathing cubicle, on which a cleaning room and an antechamber as described here are mounted, can be mounted on mobile rolling elements, such as transport rollers. The transport rollers not only allow the shower enclosure to be moved over short distances, i.e. rolled to the desired location with a precision of a few meters, but also enable transport to be carried out simply by moving the enclosure on the rollers. However, it is preferable, for example, to move the shower cubicle by combining rollers (to the desired location) and loading it onto a means of transport, such as a trailer, car, truck or similar.

[0019] According to the invention, the mobile shower and/or bathing cubicle for cleaning objects and/or users, such as people or animals, comprises at least one cleaning room within which the showering and/or bathing process can be carried out. In particular, an antechamber may be provided within which the object and/or user to be cleaned can be undressed and/or dressed.

[0020] According to at least one embodiment, the mobile shower and/or bathing cabin for cleaning objects and/or users, such as humans or animals, is characterized in that the cleaning room can only be entered if an entrance control unit releases a lock to the antechamber, and wherein the cleaning room is bounded on all sides in the horizontal direction by boundary walls, and thus the cleaning room can only be left by passing through the antechamber.

[0021] The cleaning room is preferably enclosed on all sides by cleaning walls in the horizontal direction, i.e. along the standing plane in which the user stands in the cleaning room, wherein the cleaning walls are preferably either expandable or, if they are in the form of panels, in the form of a panel mesh (these panels are then mounted non-destructively at a certain angle, preferably a right angle, for example screwed, riveted, etc.).

[0022] The cleaning room further preferably has a standing area so that the user does not have to stand on the supporting floor, for example the bare tar or the ground, which offers advantages for hygienic cleaning.

[0023] The antechamber described here may also have partition walls in the corresponding horizontal direction, i.e. in the same horizontal direction, preferably having partition walls on all sides in the horizontal direction. The antechamber and the cleaning room are connected by a preferably lockable door. The cleaning room is further preferably accessible exclusively via the antechamber.

[0024] Both the cleaning room and the antechamber can be connected to each other by means of fastening elements so that they form, at least essentially, a one-piece frame element.

[0025] The entry control element described here can be a scanner or other card reader, but a classic key lock or a wireless RFID or Bluetooth lock is also possible. Using the correct signal, the lock can therefore be opened or closed by means of wireless opening communication (e.g. RFID or Bluetooth or similar). Preferably, the lock closes automatically after entering the cleaning room, and even more preferably, the lock opens automatically after the cleaning process is completed. This can be achieved by means of appropriate sensors and electrical interconnection with the entrance control element. For example, this can be implemented by means of a knob on the outside and a latch on the inside. This allows the door to always be opened from the inside but not from the outside. Access is therefore only possible via an electric strike. Additionally lockable from the inside with a panic lock for emergencies.

[0026] If the nozzles are switched off, the lock can be reopened fully automatically after a certain period of time, for example 10 seconds or 30 seconds. However, it is also possible for the lock to be opened from the inside by the user, especially to provide an escape route, even during the fully automatic cleaning process.

[0027] In any case, when the door is opened from the inside, the cleaning process is automatically terminated by means of the entrance control element and the electrical connection to a control unit for the cleaning nozzles.

[0028] According to at least one embodiment, the access control unit comprises a key lock and/or a (chip) card access, so that only authorized persons can enter the antechamber.

[0029] The entrance control element can also include, alternatively or additionally, facial recognition, which includes pre-stored access faces (i.e. faces scanned in advance using facial recognition software) and/or fingerprint activation.

[0030] A combination of all these options is also possible for particularly secure access control to the cleaning room.

[0031] The entrance control unit is preferably designed and intended to allow only one person and/or one object to enter the cleaning room. Alternatively, a predetermined group of people can be admitted, for example parents with children.

[0032] Furthermore, a surveillance element, such as video surveillance, may be installed in the cleaning room and/or in the antechamber, but only in compliance with personal privacy interests.

[0033] However, appropriate video surveillance before entering the antechamber is also conceivable. For example, a so-called checkpoint antechamber could be arranged in front of the antechamber. This can be connected to the antechamber in the same way as the antechamber is connected to the cleaning room. The checkpoint room can then be used as an identification room. Alternatively or in addition to the access controls from the antechamber to the cleaning room, the checkpoint room can also have access control to the cleaning room. If such a checkpoint room has appropriate access control, it is conceivable that further access controls between the antechamber and the cleaning room can be dispensed with, at least in part. Access control can function according to the concept and/or by means of automatic identification and data acquisition technology (Auto-ID), such as DMC, etc. Access control can be controlled and/or adjusted via a web-based program, such as an app.

[0034] According to at least one embodiment, the entrance control unit has at least one wireless reader, such as an RFID reader, a barcode reader and/or a barcode reader or similar, or the (chip) card access includes such a device.

[0035] According to at least one embodiment, the shower and/or bathing cubicle comprises an access means comprising a key, a chip and/or a reader card, by means of which access to the antechamber is opened or blocked after data interaction with the entrance control unit.

[0036] According to at least one embodiment, the shower and/or bath cubicle is characterized in that the access means stores information in a data-technological manner which can generate a certain number of activations of the access restriction means.

[0037] For example, users are issued with a corresponding chip card in advance, which is rechargeable and corresponds to a certain number of separate, fully automatic shower cycles after recharging. Preferably, access control to at least one of the rooms, i.e. the antechamber and/or the cleaning room, is designed in such a way that re-entry is only granted after a shower session if a blocking period has been exceeded. For example, one day or two days. This avoids repeated wasting of resources and permanent occupation of individual shower cubicles by users.

[0038] According to at least one embodiment, the mobile shower and/or bathing cubicle is equipped with a downpipe heat exchanger which preheats the cold fresh water for the mixer tap by using the residual heat of the warm waste water. This heat exchanger is designed as a vertical pipe-in-pipe system, with the waste water flowing downwards and the fresh water being fed upwards in a counterflow, achieving a heat transfer efficiency of up to 70%. Compared to currently available standard shower cubicles, which do not integrate heat recovery systems or only offer simple heat exchangers with efficiencies below 40%, this represents a significant advance. The mixer tap can be connected to one or both of the supply lines from a flow heater or a fresh water station. A first advantage is the reduction in energy consumption for hot water preparation by up to 60%, which significantly reduces operating costs in low-energy environments such as remote campsites or construction sites, increasing cost-effectiveness in mobile scenarios. Another advantage is the sustainable use of resources, as the reduced dependence on external energy sources reduces CO.sub.2 emissions by up to 50% and qualifies the cabin for ecological certification, while reducing the hot water tank to 20-30 liters reduces the weight by up to 40 kg and facilitates transport in areas that are difficult to access, such as mountain regions or river deltas. The savings can be increased even further if the system has a large central water tank, especially when several showers are used at the same time. Figures of up to 50% are realistic here, which can amount to 400 liters of water or more.

[0039] According to at least one further embodiment, a lifting system is provided which lifts the warm wastewater from the low-lying shower drain to a height of at least 1.5 meters, ideally up to 2 meters, in order to ensure the necessary head for the heat exchanger. This lifting system uses an energy-efficient submersible pump with variable speed control, which is activated only when the wastewater temperature exceeds 25 C., reducing the energy consumption for pumping to less than 10% of the total consumption. Compared to standard shower cubicles, which cannot be adapted to low drain heights, this is an innovative solution that is specially tailored to the confined space of mobile cubicles and cannot be easily transferred to permanently installed systems, as these typically use higher drain heights. A first advantage is the improved heat recovery in the compact design, which increases energy autonomy by up to 20% and keeps the cabin functional in remote areas without a power supply. Another advantage is the extended service life of the mechanical components by up to 30%, as the reduced operating time of the pump minimizes maintenance in harsh outdoor conditions and ensures reliability in long-term use. It is also conceivable that the control system is set up and designed to calculate, based on a wastewater temperature and/or a feed water temperature and, if applicable, the known energy consumption of the lifting system, when it might be sensible to lift the wastewater and thus heat the feed wateri.e. in particular as soon as energy is saved.

[0040] According to at least one embodiment, a temperature-controlled bypass system is provided which bypasses the heat exchanger at wastewater temperatures below 20 C. and directs the fresh water directly to the mixing valve in order to avoid unnecessary flow resistance and energy losses. This feature is not found in current standard shower enclosures and is tailored to the variable use of mobile systems, where temperature fluctuations occur more frequently than in permanently installed showers. An initial advantage is more precise energy management, which stabilizes operation even with irregular use and reduces energy consumption by up to 15%, doubling the service life of the heat exchanger's operating batteries in remote areas with limited power supply. Another advantage is the extended service life of the lifting system, which needs to be replaced less frequently due to the lower load, reducing total costs over the lifetime of the cabin by up to 20% and simplifying logistics for spare parts in remote regions. Alternatively or additionally, control and/or regulation based on the ratio of the lifting system's output relative to a temperature difference, including, for example, the efficiency of one or more components of the system, is possible.

[0041] According to at least one further embodiment, an adaptive hot water management system is provided which reduces the hot water storage tank to a capacity of, for example, 500 liters, preferably 200 liters, most preferably 100 liters, for example 20 liters, and dynamically adapts the heating output to the available preheating energy. Compared to standard models with fixed storage sizes, this is tailored to the weight and space requirements of mobile cabins, which are less critical in fixed installations. A first advantage is improved mobility, which facilitates transport on rough terrain such as forest paths or muddy construction sites and makes the cabin suitable for smaller vehicles such as trailers, reducing logistics costs by up to 35%. Secondly, the lower heating energy allows for up to 50% longer operating time with limited batteries, which increases independence in emergency situations such as after natural disasters and strengthens supply security.

[0042] According to at least one embodiment, a predictive maintenance system is provided that is specifically tailored to the requirements of a mobile shower cabin with heat recovery. This system uses a local microcontroller that monitors the lifting system for imbalance using a 3-axis acceleration sensor and controls the heat exchanger using temperature sensors at four points. While this could also be applicable to fixed installations, the adaptation to mobile conditions such as vibrations during transport is unique. A first advantage is preventive fault detection, which reduces downtime by 85% and keeps the cabin continuously operational, relieving the supply chain. Secondly, targeted maintenance planning extends the service life of components by 40%, which increases operational reliability in remote areas with difficult spare parts supply and minimizes dependence on external service providers.

[0043] According to at least one further embodiment, local data processing is adapted to the intermittent usage patterns of mobile showers by the microcontroller distinguishing between four operating states and applying specific threshold values. For example, the heat recovery rate is calculated every 10 seconds, or at least within a specified period of time, and a drop below 60% triggers a limescale warning, which is not available in standard solutions and is specifically tailored to the unpredictable use of mobile units. The first advantage is optimized resource utilization, which enables maintenance during periods of low utilization and stabilizes operation during intensive use, such as at festivals, reducing water consumption by 25% and increasing sustainability. Secondly, precise status detection reduces maintenance costs by up to 30% by avoiding unnecessary interventions, maximizing cost-effectiveness in mobile scenarios with limited budgets such as charitable projects.

[0044] According to at least one embodiment, a machine learning system uses shower-specific parameters such as shower temperatures of 35-42 C. and shower durations of 3-8 minutes to detect anomalies when the heating time deviates by more than 30%. Adaptation to mobile conditions such as temperature fluctuations during transport distinguishes this from fixed systems. A first advantage is adaptive adaptation to regional water qualities, which reduces false alarms by 95% and increases reliability in changing locations such as tropical rainforests or arid deserts, thereby increasing flexibility. Secondly, precise anomaly detection enables proactive maintenance, which reduces downtime by 80% and keeps the cabin available for continuous use, such as in humanitarian missions, thereby increasing supply capacity.

[0045] According to at least one further embodiment, an LSTM network predicts the degradation rate of the heat exchanger based on water hardness and wastewater temperature, calculating a 1% reduction in efficiency per 100 operating hours. Taking mobile factors such as transport conditions into account makes this specific. A first advantage is preventive planning, which reduces maintenance costs by 35% by performing descaling before performance loss, which is crucial in regions with high water hardness. Secondly, the forecast minimizes failure risks in intensive usage scenarios such as large events, ensuring the availability of the cabin and increasing user satisfaction through consistent performance.

[0046] According to at least one embodiment, the system classifies shower-specific faults such as blockages caused by hair or foam formation and links them to maintenance instructions, which is something that standard shower cabins lack. The adaptation to mobile contamination risks is unique. A first advantage is fast troubleshooting, which reduces repair times by 60% and keeps the cabin operational in high-traffic applications, increasing customer satisfaction. Second, precise diagnosis reduces material consumption for unnecessary replacement parts by 30%, maximizing resource efficiency in mobile logistics and minimizing the environmental impact of waste.

[0047] According to at least one further embodiment, a digital twin simulates heat transfer taking into account limescale layers, enables what-if scenarios and optimizes energy consumption by 25%. The adaptation to mobile transport conditions is specific. A first advantage is optimization without interruption, which maximizes energy savings in remote areas and strengthens independence from external energy sources. Secondly, simulation improves maintenance planning by predicting limescale formation, which increases efficiency by 20% over the lifetime and ensures long-term cost-effectiveness.

[0048] According to at least one embodiment, maintenance optimization plans maintenance based on usage patterns, e.g. morning hours during festivals, which reduces downtime by 70% and lowers costs through bundling, as opposed to fixed intervals. Adaptation to mobile usage peaks is specific. A first advantage is flexibility, which ensures operational continuity during high demand and improves the user experience. Second, optimization reduces logistics costs by 25% by deploying technicians more efficiently, which minimizes coordination efforts in international operations.

[0049] According to at least one further embodiment, a blockchain-based system documents usage data in an immutable manner, which standard solutions lack and provides complete proof of hygiene. The adaptation to mobile data security requirements is unique. A first advantage is data security, which minimizes legal risks in public deployments and avoids liability disputes. Second, transparency facilitates financing by public authorities by providing clear usage statistics, which makes budget planning easier.

[0050] According to at least one embodiment, a greywater system recycles wastewater after filtration for self-cleaning, reducing water consumption by 50% and increasing autonomy. Adaptation to mobile water resources is specific. A first advantage is water savings in dry regions, which increases sustainability and conserves local water resources. Secondly, recycling reduces wastewater disposal costs by 40%, which is economical in urban mobile applications and reduces environmental impact.

[0051] According to at least one further embodiment, a micro-turbine generator obtains energy from water pressure, supplies the electronics and extends the operating time. The adaptation to mobile energy sources is unique. A first advantage is independence from batteries, which ensures availability in emergencies and relieves the supply chain. Secondly, energy generation reduces operating costs by 15%, which increases financial viability in long-term applications such as disaster relief.

[0052] According to at least one embodiment, a shock-absorbing frame construction is provided which dampens vibrations during transport and protects sensitive components such as the heat exchanger. This is limited to mobility, as fixed installations do not experience such stresses. A first advantage is protection against transport damage, which ensures the integrity of the cabin on uneven roads such as gravel roads and reduces failure rates by 40%. A further advantage is the extension of the service life of the components by up to 25%, which facilitates maintenance logistics in remote locations such as desert regions.

[0053] According to at least one further embodiment, a foldable transport mode is provided, which compresses the cabin for transport on trailers by folding in the walls and frame, which is not possible with fixed installations. A first advantage is the space saving, which enables transport on narrow roads such as mountain passes and reduces logistics costs by 30%. Another advantage is the faster set-up time of less than 10 minutes, which speeds up supply in emergency situations such as after earthquakes.

[0054] According to at least one embodiment, an integrated levelling system is provided which stabilizes the cabin on uneven ground by automatically adjusting hydraulic supports, which is only relevant for mobile applications. A first advantage is stability on sloping surfaces such as hillsides, which increases safety in strong winds and prevents tipping. Another advantage is the reduction in set-up time by 15 minutes, which increases efficiency in chaotic scenarios such as flood areas.

[0055] According to at least one further embodiment, a modular water treatment system is provided which filters water from natural sources such as rivers on site and adapts it for use, which is not possible with fixed systems with a fixed water connection. A first advantage is the supply of water in arid regions, which increases autonomy by 60%. A further advantage is adaptation to local water qualities, which extends the service life of the heat exchanger by 20%. One or more additional water circuits, partially or completely fed into each other, are also conceivable, which can further reduce energy consumption.

[0056] According to at least one embodiment, at least one cleaning nozzle for dispensing a cleaning fluid is set up and provided to operate fully automatically after a preset period of time and after entering the cleaning room.

[0057] For example, the cleaning nozzle is also mounted so that it can be moved in a controlled manner, so that a certain washing program can be carried out in the manner of a washing system. The cleaning nozzle is designed in such a way that during this washing process, preferably selectable by the user, a certain droplet size and/or jet thickness and/or jet hardness is preset.

[0058] According to at least one embodiment, a door to the cleaning chamber comprises a sensor system which detects when the user enters the cleaning chamber in order to start dispensing the cleaning fluid after a preset period of time.

[0059] According to at least one embodiment, the access control unit records a counting unit in terms of the number and/or duration of a showering process, in particular by means of RFID on the card, so that only one is stored on the card and/or in a memory element of the access control unit.

[0060] According to at least one embodiment, a self-cleaning process can be carried out after a preset number of times, and in particular controlled by the access control unit, so that the interior of the cleaning room is always as clean as possible for further use. A cleaning message can also be sent to the operator/cleaning staff. This can be based on the number of showers taken so far and experience values for e.g. campsites or events, as well as on the feedback switch mounted at the exit. In this context, it is conceivable that if there is too much negative feedback, a cleaning message is sent to clean the shower. This could also be understood as a backup cleaning system.

[0061] Furthermore, the present invention relates to a method for cleaning objects and/or users, such as humans or animals, in particular by means of a device according to claim 1.

[0062] The method for cleaning objects and/or users, such as humans or animals, in particular by means of a device according to claim 1, comprises, in a first step, unlocking the access control unit and then entering the antechamber, followed by the user removing their clothing.

[0063] The next step of the method is to enter the cleaning room and, by means of the access control unit or another control unit, preferably fully automatically control the cleaning nozzles to emit a cleaning fluid at a predetermined cleaning interval.

[0064] The user then leaves the cleaning room via, for example, a door or other conceptual or tactile room boundary to the antechamber, and then enters at least one cleaning room in which the showering and/or bathing process can be carried out.

[0065] In addition, the object to be cleaned and/or the user can be undressed and/or dressed within at least one antechamber.

[0066] The method for cleaning objects and/or users, such as humans or animals, in particular by means of a device, can be designed in at least one embodiment such that the cleaning room can only be entered if an entrance control unit releases a lock to the antechamber, and wherein the cleaning room is bounded on all sides in the horizontal direction by boundary walls, and thus the cleaning room can only be left by passing through the antechamber.

[0067] The method described here has the same advantages.

[0068] All features disclosed for the device described here are also disclosed for the method described here and vice versa.

[0069] The invention described here is described in more detail below with reference to an example of embodiment.

[0070] FIG. 1 shows a basic structure of the shower cubicle described here, including a switch cabinet with battery operation and water storage tank as described here.

[0071] FIG. 2 shows the corresponding access opening control, which can be implemented, for example, by means of a credit card and/or RFID and/or on the basis of an electric door opener.

[0072] FIG. 3 shows a flow chart, i.e. a sequence diagram of a self-contained showering process from the start to the end of the showering process.

[0073] FIG. 4 shows a frame and the basic structure of the cleaning room and the antechamber, as well as the corresponding side panels to be installed afterwards.

[0074] FIG. 5 shows the storage room, which has a water tank with a corresponding hot/cold water pipe distribution system for supplying the cleaning fluid to the cleaning nozzles, including or in particular those mounted on the walls (shower partition walls). The storage room described here is preferably not only constructed in the same way as the other rooms described here, but is also connected to the other rooms.

[0075] However, the storage space described here may also be connected separately to the cleaning space for supplying the cleaning fluid to the cleaning nozzles.

[0076] FIG. 6 shows various steps in the cleaning process described here, in particular a first step, which comprises switching on the cleaning nozzles, and a second step, which comprises switching on cleaning nozzles for the floor.

[0077] FIG. 7 shows additional nozzles and a corresponding drainage channel 12 within the cleaning room.

[0078] FIG. 8 shows corresponding lifting feet 11 that are capable of supporting several tonnes of weight, for example 3 tonnes of load weight.

[0079] FIG. 1 shows the mobile shower and/or bathing cabin 1 for cleaning objects and/or users, such as people or animals, with at least one cleaning room 2, within which the showering and/or bathing process can be carried out, and at least one anteroom 3, within which the object and/or user to be cleaned can be undressed and/or dressed.

[0080] FIG. 1 also shows the mobile shower and/or bathing cabin 1 for cleaning objects and/or users, such as people or animals, and that the cleaning room 2 can only be entered if an entrance control unit 4 releases a lock to the antechamber 3, and wherein the cleaning room 2 is bounded on all sides in the horizontal direction by boundary walls 5, and thus the cleaning room 2 can only be left by passing through the antechamber 3.

[0081] FIGS. 1 and 2 show that the entrance control unit 4 includes a key lock and/or (chip) card access, so that only authorized persons can enter the antechamber 3, wherein the entrance control unit 4 has at least one wireless reader, such as an RFID reader, a barcode reader and/or a barcode reader or the like, or the (chip) card access comprises such a device. This can also be controlled via an app. For example, this app can also be used to book a time slot and/or access slot for showering.

[0082] In addition, for campsites, for example, it would also be conceivable to have a permanently open operation. In this context, the door could be opened temporarily or permanently by at least one electrically operated opener (e-opener) and/or monitored to see whether the door is open or closed. The door monitoring system can enable or stop the showering process after a predetermined period of time. After leaving (door monitoring detects reopening), a cleaning process for the walls and floor can be started.

[0083] In addition, for campsites, for example, continuous operation would also be conceivable. In this context, the door could be opened temporarily or permanently by at least one electrically operated opener (e-opener) and/or monitored to see whether the door is open or closed. The door monitoring system can activate or stop the showering process after a predetermined period of time. After leaving (door monitoring detects reopening), a cleaning process for the walls and floor can be started.

[0084] The door can be locked by the user themselves, for example by locking the door from the inside. In this case, a permanently open state is also conceivable, e.g. 6 a.m. to 10 p.m.

[0085] FIGS. 1 and 2 (as well as FIG. 6) show that an access device comprises a key, a chip and/or a reader card, which, after data interaction with the entrance control unit 4, opens or locks access to the antechamber 3, whereby the access means stores readable information in a data-technological form which can generate a certain number of activations of the access restriction means.

[0086] FIGS. 1 and 2 also show that, after a preset period of time and after entering the cleaning room 2, at least one cleaning nozzle 6 is automatically activated and provided for dispensing a cleaning fluid, whereby a door to the cleaning room 2 comprises a sensor system which detects when the user enters the cleaning room 2 in order to start dispensing the cleaning fluid after this preset period of time.

[0087] FIGS. 1 and 2 also show that the access control unit 4 records the number and/or duration of a showering process, in particular by means of RFID on the card, which is automatically stored. so that only one is stored on the card and/or in a memory element of the access control unit 7 and that, after a predetermined number (for example, also after each use of the shower) and, in particular, by means of the access control unit 7, a self-cleaning process can be carried out so that an interior of the cleaning room 2 is always clean and ready for further use.

[0088] Furthermore, FIGS. 1 and 2 show a method 100 for cleaning objects and/or users, such as people or animals, in particular by means of a device according to claim 1.

[0089] The method 100 for cleaning objects and/or users, such as humans or animals, in particular by means of a device 100 according to claim 1, comprises, in a first step, unlocking the access control unit 7 and then entering the antechamber 3, followed by the user removing their clothing.

[0090] The next step of method 100 is to enter the cleaning room 2 by means of the access control unit 7 or another control unit 4, preferably fully automatically or via a switch, button or similar. Cleaning nozzles 6 are then activated to emit a cleaning fluid at a predetermined cleaning interval.

[0091] In general, however, instead of or in addition to access control, the shower can always be activated (e.g. at a campsite) and/or access is recorded by one or more access doors. This activates the shower duration or releases the start button. The shower is limited to a duration of x. After the shower room and/or the antechamber is vacated, automatic cleaning is started before the next person can enter the antechamber.

[0092] In addition, it is possible to undress and/or dress the object to be cleaned and/or the user in at least one antechamber 3.

[0093] The method 100 for cleaning objects and/or users, such as humans or animals, in particular by means of a device, is characterized in that the cleaning room 2 can only be entered if an entrance control unit 4 releases a lock to the antechamber 3, and wherein the cleaning room 2 is bounded on all sides in the horizontal direction by boundary walls 5, and thus the cleaning room 2 can only be left by passing through the antechamber 3.

[0094] FIG. 9 shows a perspective view of an embodiment with an integrated downpipe heat exchanger (20) and an upstream lifting system (21) for active heat recovery from the shower waste water system. The downpipe heat exchanger (20) is mounted vertically on a side wall of the cabin frame, with the warm waste water from the cleaning room (2) being conducted downwards through a central downpipe (22). A spiral-shaped fresh water pipe (23) is arranged around the downpipe (22), which carries the cold inlet water in a counterflow principle. The lifting system (21) is located below the cleaning chamber (2) and actively conveys the waste water to the upper inlet opening of the downpipe heat exchanger (20). The entire system is housed in a compact installation box (24) with connection couplings (25) for fresh water, waste water and power supply accessible from the front. A first advantage of this design is its space-saving integration, which allows installation in the confined space of mobile cabins and reduces installation time by up to 20%, which is crucial in chaotic deployment scenarios such as flood areas. Another advantage is the tool-free maintenance, which reduces repair costs in remote regions such as deserts by up to 30% thanks to the accessible connections.

[0095] FIG. 10 shows a schematic representation of how the heat recovery module works in conjunction with the fresh water and shower system. The warm waste water from the cleaning room (2) is pumped by the lifting unit (21) to the upper inlet opening of the downpipe heat exchanger (20) and flows downwards through the central downpipe (22). The cold fresh water is fed through the fresh water pipe (23) in a counterflow and supplied as preheated water to a mixing valve and/or a hot water preparation module. The control of the lifting system (21) is linked to the access control unit (4) so that the process is only activated when the shower is in use. An optional bypass pipe with a changeover valve (26) is shown, which bypasses the fresh water directly if required. A first advantage is the energy-efficient reduction of the heating load of the water heater by up to 60%, which reduces operating costs in low-energy environments such as campsites and increases autonomy. Another advantage is the flexibility provided by the bypass system, which ensures continuity during maintenance or contamination and reduces downtime in mobile applications such as festivals by up to 15%.
