Description

[0001] The invention relates to a wet cell or a shower cubicle, comprising at least one panel element or at least one panel element and at least one wall element, in particular for integration into a vehicle, interior furnishing element or piece of furniture, especially for an interior of a recreational vehicle.

[0002] Wet rooms and / or shower cubicles or showers, especially for integration into a vehicle, with a shower tray and a drain, are known from the prior art. Such wet rooms and / or shower cubicles include shower trays made of thermoplastics or metals. These shower trays are usually not very durable and / or are relatively heavy. Furthermore, the walls of wet rooms are limited to certain materials and designs suitable for wet room requirements. Additionally, sanitary fittings, such as water supply lines, must be placed behind the walls of the wet room, further reducing the already limited space available to the user.

[0003] The invention therefore aims to provide an improved wet room and / or shower cubicle and to solve the problems mentioned above, in particular to improve durability and / or reduce weight, as well as to increase aesthetics, the number of possible designs and the space in the wet room.

[0004] The invention solves this problem by means of a wet cell according to claim 1 and by means of a recreational vehicle equipped with a corresponding wet cell. Advantageous embodiments are specified in the dependent claims.

[0005] The invention provides a wet cell comprising at least one panel element that delimits the wet cell, wherein the panel element is made of a lightweight sandwich panel comprising a first cover layer and a second cover layer as well as a core arranged between the two cover layers and optionally a film layer arranged on at least one of the cover layers, wherein the lightweight sandwich panel is hydrophobic, waterproof and / or rot-resistant, and wherein at least one section of a side wall and at least one section of a floor of the wet cell is formed from the panel element.

[0006] The invention further provides a wet cell which comprises at least one panel element which delimits the wet cell, and at least one wall element which is arranged in the wet cell on the panel element and detachably attached to it, wherein a cavity is formed between the panel element and the wall element.

[0007] The wet cell is primarily intended for integration into a vehicle and / or a piece of furniture. In particular, the wet cell forms part of a piece of furniture that is integrated into a vehicle.

[0008] The wet cell and / or shower cubicle according to the invention essentially consists of at least one panel element, which can also be referred to as panels, wall elements, walls, surfaces and / or surface elements. The at least one panel element is variable in size, shape and / or dimensions and can be adapted to the conditions of the environment of a vehicle or an interior furnishing element.

[0009] The panel element and / or wall element is constructed in a plate-like and / or planar form, with the panel element having a greater length and width than its height or thickness. In many embodiments, the panel element is planar, meaning it extends essentially in one plane. However, there are also embodiments in which at least one section of the panel element is curved; for example, a section of the panel element can be curved and thus enclose an interior space within the wet room.

[0010] The panel and / or wall element comprises a core, a first facing layer, a second facing layer, and optionally a foil layer arranged on the first and / or second facing layer. The core is positioned between the first and second facing layers. The core, the facing layers, and the optional foil layers are themselves plate-like and / or planar and are arranged on top of or against each other. The thicknesses of the core, the facing layers, and the optional foil layers can differ. In other words, the panel element is designed as a multi-layered panel element, which can also be described as a sandwich panel or sandwich construction. The panel element is specifically designed as a lightweight sandwich panel.

[0011] In particular, the panel element and / or wall element has a central, inner core, wherein a cover layer is first arranged on each side of the core, in particular on each surface side, and optionally an outer foil layer is placed on top of it.

[0012] The core preferably comprises hollow areas, which are particularly cell-shaped. These cell-like hollow areas are arranged repeatedly, particularly along a main plane of extension of the panel element, i.e., especially along its length and width. The hollow areas can be bounded by strut elements, for example, in the form of side walls. This results in a honeycomb structure. The panel element is therefore preferably designed as a sandwich panel with a honeycomb core, whereby the honeycombs do not necessarily have to be hexagonal. Rather, it is possible for a wide variety of geometries to be formed for the cell area along a plane running parallel to the main plane of extension. Polygonal, e.g., hexagonal, rectangular or rhomboid, circular, or elliptical cross-sections are possible. In particular, the core can be open-celled, especially on the side facing the respective face sheet.Alternatively, the core can also be made of foam material, e.g. Styrofoam or foam.

[0013] The surface layers are thinner than the core and are essentially solid. The optional foil layers are also thinner than the surface layers and are essentially solid. The panel element can therefore consist of five layers. Additional layers are possible between the core and the respective surface layer, between the respective surface layer and the respective foil layer, or even on top of the respective foil layer.

[0014] In particular, all elements of the panel element and / or wall element, i.e., the core, the first and second cover layers, and the optional first and second film layers, are made of one or more plastics, in particular one or more recyclable and / or reusable plastics, and further, in particular, one or more thermoplastic plastics, or at least comprise them. Specifically, individual or all elements of the panel element are made of polypropylene and / or comprise polypropylene. Alternatively or additionally, individual or all elements of the panel element are made of polyethylene and / or comprise polyethylene. Additionally or alternatively, the elements of the panel element may comprise one or more other materials, in particular recyclable and / or reusable materials, that are not plastics or do not comprise plastics, such as natural fibers like wood.In particular, the first and / or second cover layer may contain fiber reinforcement. This fiber reinforcement can include, for example, fiberglass, plastic (e.g., aramid), carbon, or renewable materials such as wood, cork, hemp, or flax.

[0015] The thickness, height, or strength of the panel and / or wall element is, for example, between 10 mm and 30 mm, particularly between 12 mm and 20 mm. The surface weight of the panel element is, for example, between 100 g / m². 2 and 10000 g / m² 2 , especially between 1,000 g / m² 2 . and 8,000 g / m² 2 , especially between 700 g / m² 2 and 5,000 g / m² 2 .

[0016] The optional film layer can function as a decorative layer. It is preferably made of plastic, e.g., polypropylene. The film layer has a thickness of, for example, 10 µm - 80 µm, preferably 100 µm - 500 µm.

[0017] This lightweight sandwich panel of the panel element and / or wall element is hydrophobic, waterproof, and / or rot-resistant. Therefore, this panel element according to the invention is suitable for areas where low weight and water resistance are required. Thus, the panel element according to the invention, in the form of a lightweight sandwich panel, is not only suitable for side walls, movable walls, and / or ceilings of a wet room and / or shower cubicle, but also for a section or the entire floor of a wet room and / or shower cubicle. The panel element according to the invention is suitable for lining individual or extensive sections of the wet room and / or shower cubicle, up to and including lining the entire wet room and / or shower cubicle, as will be explained further below. It is also possible to create watertight connections with the panel element according to the invention, as will be explained further below.

[0018] A wet room and / or shower cubicle is at least partially or completely enclosed and / or defined by one or more panel elements. This may require connecting several panel elements together, particularly in a watertight manner. For example, one or both side walls of the wet room can each be formed by at least one panel element. These are preferably connected to a rear wall of the wet room, with each side wall forming an angle with the rear wall, e.g., a right angle. Advantageously, the side wall and rear wall are connected along their entire height. Furthermore, panel elements of the rear wall and / or side walls can also be connected to a panel element that forms the floor of the wet room. These connections should be watertight.It has been shown that a material-bonded connection, in particular an adhesive bond and / or a weld, can be used for these joints. However, with the hydrophobic and / or waterproof panel elements used, it is advantageous if the foil layer is not present in the area of ​​the material-bonded connection on the panel elements. In particular, the foil layer in the joining section—especially in the section where the connection is to be made, i.e., the section that is to bond with the adhesive or filler material during welding—can be removed before joining the panel elements, e.g., by milling. The joining section between the side wall and the back wall advantageously extends over the entire length of the panel elements to be joined, particularly along an edge to be joined. This type of connection allows, for example,Panel elements can be butted together. In particular, it is possible to place an edge of a second panel element against a top layer of a first panel element and connect them there.

[0019] Therefore, at least one plate element can have at least one connecting section in which at least the foil layer is not provided.

[0020] At least one initial connection section can be provided on a first plate element, and optionally a further connection section, corresponding to the first connection section, can be provided on a second plate element. The first and second plate elements can then be joined together by gluing and / or welding. Unlike the rest of the respective plate element, no foil layer is provided at these connection sections.

[0021] According to a first embodiment, this can be provided exclusively on one side of a first plate element. Adhesive can then be applied to this connection area, and then an edge of a second plate element can be pressed against it, thus joining the two.

[0022] According to a second embodiment, a first connecting section is provided on a first plate element, and a further connecting section, in particular corresponding to the first connecting section, is provided on a second plate element. In this embodiment as well, the two plate elements can be butted together. Advantageously, the two connecting sections can then be joined by welding or by adhesive.

[0023] In the first and second connection sections, only the foil layer may be missing, while the top layer and core remain. Alternatively, only the core may be present, and the top layer may also be missing in sections, particularly corresponding to or identical with the foil layer. The foil layer may not have been intended to be on the top layer in these sections from the outset, for example, because connection sections were already incorporated into the production process, or it may have been subsequently removed, as will be described later. These connection sections serve to fasten the panel element, as will be explained further.

[0024] For this purpose, at least one plate element is arranged such that a first connecting section and a second connecting section touch each other section by a portion of their length and form an angle between them. The first connecting section and the second connecting section are arranged next to each other so that the connecting sections touch or abut each other, particularly where the foil layer is not present.

[0025] This creates an angle between the plate elements. This angle can be between 15° and 165°, in particular between 30° and 150°, further in particular between 45° and 135°, further in particular between 60° and 120°, further in particular between 75° and 105°, further in particular between 80° and 100°, further in particular between 85° and 95°, further in particular essentially 90°, further in particular exactly 90°.

[0026] According to one embodiment, an adhesive surface is provided, which can be arranged section by section on the first connecting section and / or section by section on the second connecting section, and which can bond the plate element together in a material-bonded manner. In particular, the adhesive surface is provided on the first and second connecting sections such that it bonds or fastens the two connecting sections, and thus the plate element, together in a material-bonded and / or form-fit manner, in particular permanently, and furthermore, in a manner that cannot be removed without damage. The adhesive surface was applied, in particular, to at least one of the first and second connecting sections, and in particular to both connecting sections, after the plate element had been provided. This can be done, in particular, by applying an adhesive or bonding material, for example, using a nozzle and / or a brush.This is done, in particular, before the plate element is positioned. The adhesive material can be, in particular, a one- or multi-component adhesive, especially a two-component adhesive. The adhesive material can, for example, be polymer- and / or acrylate-based. In particular, it is an adhesive based on a silane-modified polymer, which is, in particular, free of solvents and / or isocyanates. After applying the adhesive to the first and / or second joint section, the plate element can, in particular, be positioned and subjected to the pressure required for the adhesive material to bond.

[0027] The wet cell according to the invention makes it possible to join the panel element particularly securely and durably. The absence of the foil layer improves the strength of the adhesive bond. In particular, the solution according to the invention eliminates the need for cup connectors, screws, and / or profile elements. This results in a particularly advantageous and simultaneously secure connection of at least one panel element in a wet cell and / or a shower cubicle.

[0028] According to further training, the first connection section and / or the second connection section is formed by removing the foil layer.

[0029] Removal, which can also be described as peeling, can be achieved chemically, for example by applying a solvent, or mechanically, as will be described later. According to one method, the film layer is removed by abrading it. This can be done, in particular, by a machining process. According to another method, the film layer is removed by milling. Milling is a machining process in which material is removed, primarily through the rotation of a milling tool, thereby removing the film layer.

[0030] According to further training, the first connecting section and the second connecting section have essentially the same extent.

[0031] For example, the first connecting section is 1-3 cm wide and the second connecting section is also 1-3 cm wide. Again, for example, the first connecting section is 10-100 cm long and the second connecting section is also 10-100 cm long. Also for example, the first connecting section is 0.01-1 mm high and the second connecting section is also 0.01-1 mm high.

[0032] According to a further development, the first connecting section is arranged on a surface of the plate element, and the second connecting section is arranged on an end face of the plate element. A surface is a flat side of the plate element that extends along its width and length, but not along its thickness. In particular, the surface is one of the two sides with the largest surface area of ​​the plate element.

[0033] An end face, on the other hand, is a side along which the thickness, height, or strength runs, i.e., one of the side surfaces. One of the two connecting sections is arranged on one of two surface faces, particularly in the middle and / or centrally, whereas the other of the two connecting sections is arranged on one of four end faces. This development makes it possible to securely connect even large panel elements. In particular, this development enables a particularly stable wet room and / or shower cubicle. According to a further development, the top layer is partially absent in the second connecting section. Specifically, the panel element was cut to the desired length and / or width and split along its length and / or width, and this saw and / or cut edge constitutes or forms the second connecting section. By splitting, the panel is separated, particularly along the saw or cut edge.The cut edge of the core is exposed, and neither the foil layer nor the top layer is present in this second connection section.

[0034] According to further training, the adhesive surface seals the first and / or second connection section watertight. In this context, "watertight" means that the adhesive surface is arranged and designed in such a way that no water can penetrate or pass through the first and / or second connection section, particularly into or through the core. Specifically, the area of ​​the panel elements outside the first and / or second connection section, i.e., the part where the foil layer is still present, is also designed to be watertight. In this context, "watertight" means, for example, that penetration is prevented up to a water column of at least 500 mm, 750 mm, 1000 mm, 1500 mm, 2000 mm, 3000 mm, 5000 mm, 10000 mm, 20000 mm, or 50000 mm.

[0035] This training will enable the construction of a waterproof wet room and / or shower cubicle.

[0036] According to further training, the first and / or second connection section was subjected to plasma treatment before the adhesive surface was applied. Specifically, the first and / or second connection section was subjected to plasma treatment after the removal of the foil layer. Furthermore, no further treatment was performed on the first and / or second connection section after the removal of the foil layer and / or before the application of the adhesive surface. In this context, plasma treatment comprises the exposure and / or application of plasma to the first and / or second connection section. Plasma is a mixture of particles that includes, for example, ions, free electrons, and / or neutral atoms or molecules. This can be achieved using a suitable plasma source and / or a plasma emitter.In particular, the first and / or second bonding section can be treated with a low-pressure plasma. This plasma treatment serves primarily to clean and / or remove particles that could impede or impair the adhesion of the bonding surface.

[0037] This further training makes it possible to bond the panel elements together in a particularly durable and long-lasting manner.

[0038] According to further training, no material is applied to the first connection section and / or the second connection section, with the exception of the adhesive surface.

[0039] In particular, no material was applied to the first and / or second joint section after the removal of the foil layer. Furthermore, and specifically, no material was applied to the first and / or second joint section immediately after the removal of the foil layer, immediately before and / or after the plasma treatment, and / or immediately before the application of the adhesive surface. In this context, material application includes the addition of a material. Specifically, no primer was added to or applied to the first and / or second joint section. Furthermore, and specifically, with the exception of the optional plasma treatment described above, no further pretreatment with substances and / or reactants, and in particular not with solvents, was carried out.This advanced training enables particularly quick and easy production of a wet cell. In particular, it also enables a particularly environmentally friendly production process, as potentially harmful primers and base coats can be avoided.

[0040] In the present invention, the fixing of the plate element can also be achieved in the form of a weld seam, which is arranged in the area of ​​a deformation of the plate element and joins the plate element together in a material-bonded manner.

[0041] In particular, the weld seam is designed on the plate element in such a way that it connects or fastens the plate elements together in a material-bonded and / or form-fit manner, in particular permanently, and furthermore in a manner that cannot be removed without damage. The weld seam is specifically arranged or provided within the defined angle.

[0042] The weld was specifically designed to be formed after the plate element had been provided and positioned. The weld can be created, in particular, by applying heat and / or pressure. Specifically, the weld is formed, at least partially, from the surface layer and / or the core, for example, because it has been heated above its melting point, particularly by applying an external heat source such as a heating wire, a heating probe, a heated or hot gas, and / or a laser beam.

[0043] Alternatively or additionally, the weld seam can also be applied by adding material, for example by material feed, particularly of a plastic, and especially of the same material as the cover layer and / or the core. In particular, the weld seam can also be applied or arranged by high-frequency welding, ultrasonic welding and / or vibration welding.

[0044] The component according to the invention enables the panel element to be joined together in a component in a particularly secure and durable manner. The absence of the foil layer significantly improves the strength of the welded joint. In particular, the solution according to the invention eliminates the need for cup connectors, screws, and / or profile elements. This results in a particularly advantageous and simultaneously secure connection of the panel element within a component in a region of the panel element with at least one deformation. According to a further embodiment, the weld seam seals the first and / or the second connection section watertight. The weld seam provides a watertight seal to the connection section and, in particular, to the panel element.

[0045] Even when using a weld, further training is possible, as mentioned herein in relation to the adhesive mechanism.

[0046] According to a further aspect of the present invention, a wet cell is provided which comprises at least one panel element that delimits the wet cell and at least one wall element which is arranged in the wet cell on the panel element and detachably attached thereto, wherein a cavity is formed between the panel element and the wall element. The wall element also functions as a decorative panel. It can be provided with a different foil layer (decorative foil) than the panel element.

[0047] The at least one wall element is detachably arranged and attached to the at least one panel element. Because a gap exists between the panel element and the wall element, a cavity is formed, which opens up versatile usage possibilities. The at least one wall element can therefore be flexibly positioned on the at least one panel element.

[0048] This allows for an increase in the number of possible designs and / or decors for the wet room and more flexible adaptation to user preferences. The wall element is variable in size, shape, and / or dimensions and can be adapted to the specific conditions of the vehicle's environment or interior design element, particularly the wet room and / or shower cubicle. This enhances and improves the aesthetics. The panel element preferably forms a side wall or part of a side wall of the wet room. The wall element and the panel element are preferably both flat, extending essentially in the same plane. The wall element can, for example, have a surface area of ​​1 / 16 to 4 / 5, preferably 1 / 8 to 1 / 2, of the panel element. The wall element is attached, in particular, at a distance of 4 mm to 5 cm, preferably 1-2 cm, from the panel element, essentially suspended in front of it. The resulting cavity has a width of, for example, 4 mm to 5 cm, preferably 1-2 cm.

[0049] The wall element preferably has the same structure as the panel element, i.e., in particular, it comprises a core, a first facing layer, a second facing layer, and optionally a foil layer arranged on the first and / or second facing layer. Preferably, the foil layer is a decorative layer. The wall element is preferably hydrophobic, waterproof, and / or rot-resistant.

[0050] According to one embodiment of the present invention, a wet cell is provided, wherein the cavity is configured to accommodate a functional device, and the wall element is configured to conceal the functional device or an opening in the panel element.

[0051] Furthermore, at least one wall element can be easily removed, for example, if a wall element is worn or if the design needs to be changed. Additionally, fixtures, such as functional components necessary for the operation of the wet room and / or shower cubicle, located behind it, can be more easily accessed and, if necessary, repaired and / or replaced.

[0052] Depending on the requirements of the facilities and / or the users, two, three, four, five, six or more wall elements can be integrated into the wet room in any area of ​​the wet room and / or shower cubicle.

[0053] According to one embodiment of the present invention, a wet cell is provided, wherein the cavity is not sealed towards the wet cell. This allows the at least one wall element to be removed and, if necessary, replaced particularly easily, quickly, and flexibly. The cavity is preferably wide enough to allow any moisture penetrating it to evaporate effectively. Due to the hydrophobic, waterproof, and / or rot-resistant properties of the panel element and the wall element, sealing is unnecessary; the cavity can be part of the wet cell and be filled with shower water. Preferably, the cavity is open at the bottom and / or on at least one side. In other words, the wall element does not extend all the way to the floor and / or to at least one side wall of the wet cell, so that a gap remains at the bottom and / or on at least one side through which water can drain from the cavity.

[0054] According to one embodiment of the present invention, a wet cell is provided, wherein the wet cell is a wet cell of a recreational vehicle and / or the wet cell is a shower cubicle, in particular for an interior space.

[0055] This enhances the comfort, aesthetics, and design options of a recreational vehicle. Furthermore, it reduces the vehicle's weight, as the wet room, thanks to its lightweight sandwich panel construction, is lighter than conventional wet rooms known from current technology.

[0056] According to one embodiment of the present invention, a wet cell is provided, wherein the at least one wall element has a passage through which a sanitary connection, which is arranged in the cavity, can be connected to a sanitary installation in the wet cell.

[0057] According to one embodiment of the present invention, a sanitary control element of the sanitary installation in the wet cell is arranged on the side facing away from the cavity, wherein the wall element is designed to cover an opening in the panel element, wherein the opening in particular provides access to an installation element of a recreational vehicle, in particular to an expansion tank of a hot water heating system, in particular the hot water heating system of a recreational vehicle.

[0058] In the prior art, equipment, such as functional components necessary for the operation of the wet room and / or shower cubicle, is arranged behind the wet room and / or shower cubicle to protect it from water. Some of this equipment must be operated and / or controlled from within the wet room and / or shower cubicle. The arrangement and use of at least one wall element in the present invention makes it possible to arrange at least some of this equipment, at least partially, within the wet room and / or shower cubicle, as this wall element protects it, at least partially, from water contact.

[0059] Furthermore, it is possible to attach operating and / or control elements for equipment, for example functional equipment, to at least one wall element in order to enable and ensure operation and / or control of the equipment from the wet room.

[0060] According to one embodiment of the present invention, the wall element has a fastening element and the panel element has a fastening receiving element corresponding to the fastening element, whereby the wall element and the panel element can be detachably fastened to each other without damage and / or can engage with each other, for example by utilizing gravity.

[0061] There are numerous ways in which at least one wall element can be detachably attached to at least one panel element. For example, any type of holding and / or hanging mechanism and / or any type of support and / or laying mechanism that enables and ensures a detachable and stable connection. A preferred method of attachment involves simply inserting or hanging the wall element in front of the panel element, preferably at a defined distance. In one embodiment, one or more tabs are attached to the panel element and one or more corresponding hooks are attached to the wall element. It is preferred that a user can then remove and reinsert the wall element themselves.

[0062] According to one embodiment of the present invention, a wet room is provided which does not contain any thermoformed parts. In particular, the wet room preferably has a single-walled construction. The panel element is showerable on the inside, but decorative on the outside. The wet room, and especially its floor, is watertight and therefore does not require a thermoformed shower tray. This enables a simplified construction of a wet room, which, due to the lightweight panel construction of the at least one panel element, also allows for a weight reduction compared to the prior art.

[0063] According to one embodiment of the present invention, a wet cell is provided, wherein the cavity is designed to accommodate a shelf, in particular a shelf for hygiene articles, a warm air heater, a hot water heater, and / or a light.

[0064] By creating a cavity between at least one panel element and at least one wall element, it becomes possible to utilize this cavity and thereby save space and / or material. This leads to lower costs and better use of the limited space in a wet room and / or shower cubicle.

[0065] At least one shelf can be integrated into the cavity in a space-saving manner, eliminating the need for a separate, additional structure. This saves both space and material. Furthermore, the shelf is removable and can be easily installed and removed. It can take the form of a mesh shelf, a shelf board, a basket, or a grid, primarily made of metal or plastic. The shelf is particularly suitable for storing hygiene products.

[0066] For example, a warm air heating system and / or hot water heating system implemented in the wet room can be integrated into a space-saving cavity between at least one panel element and at least one wall element. This placement in the cavity does not negatively affect the aesthetics of the wet room and preserves them. Furthermore, the warm air heating system and / or hot water heating system can increase the quality and comfort of the wet room without further reducing its usable space.

[0067] Lighting can also be integrated into the cavity in a space-saving manner, eliminating the need for a separate, additional structure for such storage. This saves space and materials. In particular, it avoids the need for ceiling lighting in the wet room, which would require additional supply and drainage lines to a remote location, thus consuming more material and space.

[0068] Furthermore, the necessary supply and drainage lines and cables for functional equipment such as sanitary facilities, warm air heating, and / or hot water heating can be optimally routed from the cavity through the section behind it of at least one panel element in the wet room. The cavity can be positioned appropriately within the wet room by placing at least one wall element, thus ensuring optimal utilization of the available space.

[0069] According to one embodiment of the present invention, a wet cell is provided wherein the wall element is replaceable and / or wherein the wet cell is completely recyclable.

[0070] As described above, the design of the present invention offers the advantage of the simple and uncomplicated interchangeability of at least one wall element, as well as the other advantages mentioned above.

[0071] Furthermore, the use of materials described above enables complete recycling of the materials used.

[0072] Furthermore, at least one circulation system for drying is present in the wet room. This circulation system can be located in the upper and / or lower area of ​​the wet room. Alternatively, the circulation system can be integrated into at least one cavity, offering the advantages already described.

[0073] The production of the panel element and / or the wall element, and thus the entire wet cell, can be carried out through industrial production using gluing robots and / or process-reliable connectors.

[0074] Furthermore, the present invention described herein enables the creation of numerous wet cell geometries, all of which can be manufactured on the same production line. This makes it possible to produce a wide variety of geometries and / or designs cost-effectively. In addition to angular geometries with various angled arrangements of the side walls and / or floor as described above, round, semicircular, semi-circular, oval, and / or elliptical geometries with all angled arrangements are also possible. This allows the shape, design, and / or decor of the wet cell and / or shower cubicle to be flexibly adapted to the geometric requirements. The wet cell and / or shower cubicle can be designed specifically for the vehicle, interior element, or piece of furniture, particularly for the interior of a recreational vehicle.

[0075] Thanks to the at least one wall element, which can be flexibly attached to the at least one panel element in various positions, it is possible for the basic structure of the wet room to remain the same, while the design and / or decor can be adapted as desired by means of the wall elements.

[0076] Furthermore, a joint sealing tape can be used in the upper area of ​​the wet room and / or shower cubicle, for example to seal at least one section of this upper area.

[0077] According to one embodiment, a vehicle and / or a recreational vehicle is specified that includes a wet cell according to one or more of the embodiments described above.

[0078] In particular, the vehicle includes one or more pieces of furniture that comprise and / or are formed from at least one or more such wet rooms. The vehicle may, in particular, be a recreational vehicle, also known as a caravan, motorhome, or RV.

[0079] Such a recreational vehicle includes, in particular, a living area in which one or more such wet rooms, especially one or more pieces of furniture with one or more such wet rooms, are arranged or present. Such a recreational vehicle also preferably has a drive system, for example an internal combustion engine and / or an electric drive, with which it can move independently.

[0080] Alternatively, the vehicle is a trailer, in particular a caravan, which can also be called a motorhome, and which includes such a wet room and / or a piece of furniture with such a wet room. Such a trailer can also include a living area as described above, but is typically not designed to move independently, but is usually towed by a tractor.

[0081] Alternatively or additionally, the vehicle is a watercraft, such as a ship and / or boat.

[0082] According to one embodiment, a wet cell and / or a shower cubicle is specified, which is particularly suitable for integration into a vehicle or a piece of furniture and which has been described by one or more of the embodiments described above.

[0083] Regarding the embodiments and / or further developments of the vehicle according to the invention and their advantages, reference is made to the previously described embodiments and / or further developments of the wet cell and / or shower cubicle according to the invention.

[0084] The invention makes it possible to provide an improved, particularly watertight, wet room and / or shower cubicle, especially by incorporating a fastening system for the panel element. In particular, the wet room and / or shower cubicle according to the invention enables at least one panel element to be joined together in a wet room and / or shower cubicle in a particularly secure and durable manner. Specifically, the solution according to the invention eliminates the need for cup connectors, screws, and / or profile elements. This results in a particularly cost-effective and simultaneously secure connection of a panel element in a wet room and / or shower cubicle.

[0085] The invention will now be explained in more detail with reference to exemplary embodiments and the accompanying drawings. Identical or corresponding parts are identified in the drawings by the same reference numerals.

[0086] The drawings show: Fig. 1 a schematic perspective view of a section of a wet cell according to an embodiment of the invention; Fig. 2 a schematic perspective view of a section of a wet cell according to an embodiment of the invention; Fig. 3 a schematic perspective view of a wet cell according to an embodiment of the invention; and Fig. 4 A schematic perspective view of a wet cell according to an embodiment of the invention.

[0087] Fig. 1 and Fig. Figure 2 shows a schematic perspective view of a section of a wet cell 10 according to an embodiment of the invention. In particular, a corner is shown where two side walls formed by panel elements meet. Fig. 1. Connecting sections 140 and 240 can be seen in Fig. 2. Additionally, a weld seam 300. This connects the plate elements to each other by a weld joint according to the invention. Alternatively, an adhesive bond can also be provided instead of a weld joint, as described herein.

[0088] The wet cell 10 is particularly suitable for integration into a vehicle or piece of furniture and comprises a panel element 100, 200, which has a core 110, 210, a cover layer 121, 122, 221, 222 on each side of the core 110, 210 and an optional foil layer 131, 132, 231, 232 arranged on the respective cover layer 121, 122, 221, 222. The core 110, 210 has the greatest extent along the thickness D1, D2, the front and rear cover layers 121, 122, 221, 222 have a smaller extent along the thickness D1, D2 and are essentially the same thickness, and the front and rear foil layers 131, 132, 231, 232 have an even smaller extent along the thickness D1, D2 and are also essentially the same thickness.

[0089] The plate element 100, 200 thus comprises, for example, a total of five layers, which can also be described as a sandwich panel. The plate element 100, 200 can be described as plate-shaped and has a greater extent along its width B1, B2 and / or length L1, L2 than along its thickness D1, D2, which can also be described as its thickness or height. The plate element 100, 200 has a principal plane of extension that extends along its length L1, L2 and width B1, B2. The respective opposing surfaces extending along length L1, L2 and width B1, B2 can also be described as surface faces, whereas the other four sides, of which two are also opposite each other, and which extend along length L1, L2 and thickness D1, D2 or along width B1, B2 and thickness D1, D2, can also be described as end faces.

[0090] The plate element 100 has a first connecting section 140, and the plate element 200 has a second connecting section 240. The foil layer 131 is partially absent on one side of the connecting sections. The first connecting section 140 is located on one surface of the plate element 100, and the second connecting section 240 is also located on a surface, but at the end of the plate element 200.

[0091] After the plate elements 100, 200 have been provided, a welded connection 300 can then be arranged section by section, in particular in the present case completely, on the connecting sections 140, 240 in order to connect the plate elements to each other in a watertight manner.

[0092] Fig. 3 and Fig. Figures 4 each show a schematic perspective view of a wet cell 10 according to one embodiment of the invention. The wet cell has side walls formed by panel elements 100 and 200. A rear wall and a floor of the wet cell are also shown, which are likewise constructed from panel elements 100 and 200. Fig. 3 and Fig. Figure 4 also shows, by way of example, the plate element 100, 200 of the floor with deformations 704, 705 on the floor of the plate element 100, 200.

[0093] In addition to the panel element 100, 200, this schematic perspective view shows two wall elements 400, 410 as examples. These two wall elements 400, 410 are arranged, for example, in the upper and lower areas of a panel element 100, 200, which forms the rear wall of the wet room. A cavity 500, 510 is formed between a panel element 100, 200 and a wall element 400, 410, which here forms a gap of approximately 2-3 cm in width.

[0094] This cavity 500, 510 is suitable for accommodating a functional device. Fig. 3 and Fig. Figure 4 shows, as an example of a sanitary installation 600, a shower head 600 with a corresponding holder.

[0095] The upper wall element 400 can, for example, cover an opening in the panel element behind it. This opening is necessary to provide access to an installation component of a recreational vehicle, particularly an expansion tank for a hot water heating system. When the shower head 600 is removed from its holder, the upper wall element 400 can simply be hung down to expose the opening. However, when the wall element 400 is in place, the wet room can be used as a shower without any problems; the wall element 400 protects the opening from shower water.

[0096] The lower wall element 410 advantageously conceals the sanitary connection 600, as shown in Fig.Figure 4 shows that additional water connection pipes run behind the wall element 410. Furthermore, a shelf, for example for toiletries, such as a basket, can be advantageously installed in the cavity 500 at the upper edge of the wall element 410. A gap is advantageously left between the underside of the wall element 410 and the shower floor to allow shower water to drain away. This ensures good ventilation of the cavity behind the decorative panel 410, eliminating the need for sealing, as it dries very well after showering. Additionally, a lighting fixture can be installed in the cavity, providing decorative indirect lighting for the wet room.
