Description

[0001] The invention relates to a body structure for the body of an electrically powered motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to an electrically powered motor vehicle with such a body structure and to an arrangement of a charging line in the motor vehicle for electrically connecting an electrical energy storage device of an electrically powered motor vehicle to a charging socket of the motor vehicle according to the preamble of claim 8.

[0002] Body structures for electrically powered vehicles are already well known in the general state of the art. Such a body structure can have a cable receptacle designed for a charging cable. In this context, the charging cable is understood to be a conductor element designed to carry electrical current. For example, the charging cable is designed as a cable. The charging cable can be arranged, or is already arranged, in the cable receptacle, thereby allowing an electrical energy storage device of the vehicle to be electrically connected to a charging socket of the vehicle via the charging cable located in the cable receptacle. This charging cable is conventionally routed, in particular, through an interior space of the vehicle body to the charging socket, meaning that the charging cable runs, at least partially, through the interior space.However, this can have a negative impact on the design of the vehicle's installation space or body.

[0003] Furthermore, DE 10 2020 101 867 B4 discloses a battery system for an electrically powered vehicle, wherein the vehicle has a chassis component which can be arranged above the battery system, wherein the vehicle also has an electric drive, with a battery housing which is designed to accommodate at least one electric battery, wherein the battery housing has a cable connection to which an electrical cable can be connected in order to electrically contact the electric battery, and a cable channel which has a semi-open receiving space for receiving the electrical cable and a mounting wall delimiting the semi-open receiving space, wherein the semi-open receiving space faces the battery housing, and wherein the mounting wall faces away from the battery housing and is designed to attach the cable channel to the chassis component above the battery housing.

[0004] Furthermore, a motor guidance component for an electric vehicle is known from US 2018 / 0 162 447 A1.

[0005] Furthermore, WO 2024 / 221 153 A1 reveals a chassis for a vehicle.

[0006] Furthermore, it is known from JP 2000 108 948 A that a battery box is attached to a base plate from below.

[0007] The object of the invention is to create a body structure for a body of an electrically powered motor vehicle, an electrically powered motor vehicle and an arrangement of a charging line in an electrically powered motor vehicle, so that the motor vehicle can be designed to be particularly space-saving.

[0008] This problem is solved according to the invention by a body structure for the body of an electrically powered motor vehicle with the features of claim 1, by an electrically powered motor vehicle with the features of claim 6, and by an arrangement of a charging line in an electrically powered motor vehicle with the features of claim 8. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0009] A first aspect of the invention relates to a body structure for a car body, in particular for the rear section of the car body, of an electrically powered motor vehicle. In this context, the term "body structure" refers to at least a partial section of the car body, for example, an assembly. For instance, the car body, particularly in its fully manufactured state, comprises the body structure or assembly. The car body can also be referred to as the vehicle body. In this context, the term "rear section" refers to the rear substructure.

[0010] The motor vehicle is, for example, designed as a passenger car. The fact that the motor vehicle is electrically powered means that it has at least one electric motor by which it can be powered or is powered. Thus, the motor vehicle is designed as a battery electric vehicle (BEV) or as a hybrid vehicle, in particular a plug-in hybrid vehicle (PHEV).

[0011] The body structure has at least one cable receptacle designed for a charging cable, particularly an electrical one, in which the charging cable can be or is arranged. In other words, the charging cable can be accommodated or is accommodated in the cable receptacle. The cable receptacle can be understood, in particular, as a space provided for the charging cable. Thus, the charging cable, especially in its installed position in the motor vehicle, extends within or along the cable receptacle.

[0012] The charging cable is designed to electrically connect an electrical energy storage device of the motor vehicle to a charging socket of the motor vehicle. In other words, the electrical energy storage device and the charging socket are electrically connectable, particularly for charging the electrical energy storage device. Thus, the electrical energy storage device can be supplied with electrical energy via the charging socket and the charging cable, specifically for charging the electrical energy storage device. The electrical energy storage device is preferably designed as a battery or accumulator. Preferably, the electrical energy storage device is designed as an electrical traction energy storage device.This means that the electric machine can be supplied with, or is supplied with, electrical energy, particularly energy stored or chemically bound in the electrical energy storage device, to power the vehicle. For example, the electrical energy storage device is a high-voltage component. The charging socket can also be referred to as a charging port. In this context, the charging socket is understood to be a charging device through which the vehicle can be supplied with electrical energy, particularly via the charging cable, to charge the electrical energy storage device. For this purpose, a charging plug can be inserted into the charging socket. The charging plug is, for example, part of an external energy supply device related to the vehicle, such as a charging station, a wallbox, or the like.

[0013] Because the charging cable can be arranged in the cable receptacle area, or because the vehicle body structure includes such a receptacle, the electrical energy storage device can be electrically connected to the charging socket via the charging cable arranged or to be arranged in the cable receptacle area. In other words, the charging cable, which is to be accommodated or is accommodated in the cable receptacle area, is electrically connectable or coupled to the electrical energy storage device and the charging socket, particularly a charging port, especially for charging the electrical energy storage device. This means that the electrical energy storage device and the charging socket are electrically connected to each other via the charging cable when the charging cable is arranged in the cable receptacle area.

[0014] The body structure, for example, has a receiving area provided for the electrical energy storage device, in which the electrical energy storage device can be arranged or is arranged, in particular to be held or is held.

[0015] In order to design the motor vehicle, and in particular the body, in a particularly space-saving manner, the invention provides that the cable receptacle extends at least partially through a load-bearing structural component of a floor assembly of the body, in particular the body structure, whereby the charging cable arranged or to be arranged in the cable receptacle runs through the load-bearing structural component. In other words, the cable receptacle, and in particular the charging cable arranged in the cable receptacle, extends at least partially through the load-bearing structural component, that is, at least partially within the load-bearing structural component. This means that the charging cable can be routed through, or is routed through, the load-bearing structural component at least partially.Thus, the load-bearing structural component has, in particular, at least one cavity within which the cable receptacle, especially the charging cable, runs, at least partially. This means that the charging cable can be arranged, at least partially, within the cavity. In particular, the cable receptacle is formed, at least partially, by the load-bearing structural component, especially by its cavity. The term "load-bearing" can be understood to mean, in particular, that the stiffness and / or strength of the body structure, especially the body itself, is at least significantly influenced by the structural component. This means that the stiffness and / or strength depends on the structural component. The load-bearing structural component is part of the body's floor assembly. In other words, the body structure is designed as the floor assembly of the body.Thus, in this case, the structural component extends in the vertical direction of the vehicle in a lower part of the body.

[0016] The invention is based in particular on the following findings and considerations: In principle, it is conceivable to route the charging cable through the interior of the vehicle, bypassing the load-bearing structural component, to the charging socket or charging pot. However, routing the charging cable from the electrical energy storage device to the charging pot through the interior may not be possible or may be particularly challenging due to the required installation space. Conventional routing of the charging cable can therefore negatively impact the installation space required, for example, for other vehicle components.

[0017] In contrast, because the cable receptacle area in the body structure according to the invention extends at least partially through the supporting structural component, the installation space of the motor vehicle or the body can be designed in a particularly space-efficient manner, thereby avoiding installation space problems in the interior. This can be achieved in particular by routing the charging cable around the interior via the structural component, thus bypassing the interior. Furthermore, the structural component, which is designed particularly as a hollow part, can already contain installation space that can be used for routing, at least partially, the charging cable through the structural component, in particular by threading it through the structural component.

[0018] Furthermore, a wheel arch of the body structure or the body itself is attached to the rear of the load-bearing structural component in the longitudinal direction of the vehicle, in particular directly. This means that the wheel arch is located behind the structural component in the longitudinal direction of the vehicle and is specifically connected to it. The wheel arch is designed to accommodate a vehicle wheel. This means that the wheel arch at least partially defines or forms a receiving area for the vehicle wheel. In this context, the term "vehicle wheel" refers to a ground contact element by which the vehicle can be supported or is supported on a surface, such as a roadway.

[0019] Furthermore, it is provided that the cable receptacle is partially formed by the wheel arch. In other words, the cable receptacle, or rather the charging cable, runs through the wheel arch to the charging socket. Thus, it is specifically provided that the charging cable is located at least at the wheel arch, and in particular, runs through the wheel arch. This allows the charging cable, which, for example, exits laterally from the structural component in the transverse direction of the vehicle, to be routed to the charging socket via the structural component and the wheel arch, thereby bypassing the interior. This allows for a particularly space-efficient design of the vehicle's installation space, or rather, the bodywork.

[0020] Preferably, the load-bearing structural component is designed as a longitudinal member. This means that the structural component is a longitudinal member. In other words, the cable receptacle extends at least partially through the longitudinal member of the body structure, whereby, in particular, the charging cable arranged or to be arranged in the cable receptacle runs through the longitudinal member. This means that the cable receptacle, and especially the charging cable arranged in the cable receptacle, extends at least partially through the longitudinal member, that is, at least partially within the longitudinal member. Thus, the longitudinal member preferably has the aforementioned cavity within which the cable receptacle, and especially the charging cable, runs at least partially. In particular, the cable receptacle is formed at least partially by the longitudinal member, especially by its cavity.This allows the vehicle to be designed in a particularly space-saving manner, as, for example, the interior can be bypassed with minimal effort. Overall, it is evident that the body structure according to the invention allows the charging cable to pass through the longitudinal member, which is designed in particular as the rear longitudinal member.

[0021] In a further embodiment, the load-bearing structural component has an opening facing inwards in the transverse direction of the vehicle, through which the charging cable can be inserted, particularly directly, into the load-bearing structural component. In other words, the opening is located on the inside of the load-bearing structural component with respect to the transverse direction of the vehicle, and the cable receiving area, particularly the charging cable, extends through the opening into the structural component. Thus, a portion of the cable receiving area extending outside the structural component opens through the opening into the cavity, i.e., into the structural component. This allows for the insertion of the charging cable into the structural component in a particularly efficient manner, enabling the charging cable to pass through the structural component.

[0022] In a further embodiment, it is provided that the cable housing area runs at least between a connection point intended for connecting the charging cable to the electrical energy storage device and the load-bearing structural component, in particular the wheel housing, for example the charging socket, bypassing the interior. In other words, the charging cable runs at least between the connection point and the structural component, in particular the wheel housing, for example the wheel track, bypassing the interior. This means that the cable housing area or the charging cable extends in an external space of the vehicle or body located outside the interior. The external space is, for example, a wet space, whereas the interior is preferably a dry space. Thus, the interior is preferably sealed from the external space by means of at least one sealing element.By bypassing the interior space, the interior can be designed to be particularly space-efficient.

[0023] In a further embodiment, the longitudinal beam is designed as a die-cast component, in particular an aluminum die-cast component. This means that the longitudinal beam is manufactured using die casting, specifically aluminum die casting. This allows the longitudinal beam to be manufactured with minimal heat input and in a particularly weight-efficient manner. The longitudinal beam can therefore also be referred to as an aluminum die-cast longitudinal beam.

[0024] In a further embodiment, it is provided that the cable receptacle and / or the charging cable run through a main load path in the rear of the vehicle body. In other words, the cable receptacle, and in particular the charging cable located within it, passes through the structural component in the area of ​​the main load path. This allows the charging cable to be routed in a particularly space-saving manner.

[0025] A second aspect of the invention relates to an electrically powered motor vehicle which has a body structure according to the first aspect of the invention.

[0026] Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention and vice versa.

[0027] Preferably, the charging cable arranged in the cable receiving area runs, in particular directly, through the supporting structural component, in particular the longitudinal beam.

[0028] Preferably, the electrical energy storage device is designed as an underfloor storage unit. This means that the electrical energy storage device is located on the underside, i.e., on a side of the vehicle facing downwards in the vehicle's vertical direction. Thus, the electrical energy storage device is, for example, located under a floor element, such as the main floor of the vehicle body. This embodiment is based on the understanding that, especially when the electrical energy storage device is designed as an underfloor storage unit, routing the charging cable from the electrical energy storage device through the interior to the charging socket can be particularly challenging from an installation space perspective. By routing the charging cable through the load-bearing structural component, the vehicle's installation space can be designed to be particularly advantageous.

[0029] Overall, it is evident that the longitudinal member, and in particular its opening, can create an additional interface for the charging cable. This allows the charging cable to be threaded through the longitudinal member, especially the rear one, from the electrical energy storage unit into the wet area (underfloor) to the wheel arch, and from there to the charging socket. The charging cable can thus remain in the wet area, keeping the dry area free of the charging cable.

[0030] A third aspect of the invention relates to an arrangement of a charging cable in the vehicle, in particular in a cable receiving area of ​​the vehicle's body structure, for electrically connecting an electrical energy storage device of an electrically powered motor vehicle to a charging socket of the motor vehicle. The motor vehicle is preferably a motor vehicle according to the second aspect of the invention. The body structure is preferably a body structure according to the first aspect of the invention. Advantages and advantageous embodiments of the first and second aspects of the invention are to be regarded as advantages and advantageous embodiments of the third aspect of the invention, and vice versa.

[0031] In order to design the installation space of a motor vehicle or its body in a particularly space-saving manner, the invention provides that the charging cable runs at least partially through a load-bearing structural component, in particular a longitudinal member, of the motor vehicle's body. In other words, the charging cable is or is routed at least partially through the load-bearing structural component. This means that the charging cable is embedded in the load-bearing structural component, at least partially, i.e., at least along a certain length, whereby the charging cable is preferably completely surrounded by the structural component, i.e., by material of the structural component, particularly along that length.

[0032] Furthermore, it is planned that a wheel housing will be attached to the structural component in the longitudinal direction of the vehicle to the rear, with the cable intake area being formed in some sections by the wheel housing.

[0033] A further aspect of the invention relates to a method for arranging a charging cable in the vehicle for electrically connecting an electrical energy storage device of an electrically powered motor vehicle to a charging socket of the motor vehicle. In this method, the charging cable is guided, at least partially, through a longitudinal member of the vehicle's body, in particular threaded through the longitudinal member. The method can be understood, in particular, as a method for manufacturing the electrically powered motor vehicle. Advantages and advantageous embodiments of the first, second, and third aspects of the invention are to be considered as advantages and advantageous embodiments of the further aspect, and vice versa.

[0034] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0035] The invention will now be explained in more detail with reference to a preferred embodiment and the drawings. The drawings show: Fig. 1 a schematic and perspective partial sectional view of an electrically powered motor vehicle with a body structure according to the invention; and Fig. 2 a schematic and perspective partial view of a body structure according to the invention; and Fig. 3 a further schematic and perspective partial view of a body structure according to the invention; and Fig. 4 a schematic and perspective partial view of another body structure; and Fig. 5 a schematic and perspective partial view of another electrically powered motor vehicle with another body structure.

[0036] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

[0037] Fig. Figure 1 shows a schematic and perspective partial sectional view of an electrically powered motor vehicle 1, which has a body structure 2, which is designed, for example, as the rear structure of the body. Fig. Figure 2 shows the body structure 2 in a schematic and perspective partial view. As in Fig. As shown in Figure 1, the electrically powered motor vehicle 1 has an electrical energy storage device 3, which in this case is designed as a battery or accumulator. Furthermore, the motor vehicle 1 has a charging line 4 for electrically charging the electrical energy storage device 3, which in this case can be electrically connected to or is connected to the electrical energy storage device 3 at a first connection point 5. The body structure 2 has a cable receptacle 6 provided for the charging line 4, in which the charging line 4 can be arranged or is arranged, whereby the charging line 4 of the electrical energy storage device 3, arranged in the cable receptacle 6, is connected to a cable not in Fig. 1 and Fig. The charging socket of the motor vehicle 1 shown in 2 is electrically connectable or is connected, in particular to charge the electrical energy storage device 3.

[0038] As in Fig. 1 and Fig. As can be seen in Figure 2, the body structure 2 has at least one load-bearing structural component 7, which in this embodiment is designed as a longitudinal member 7a. A main extension direction of the longitudinal member 7a runs at least substantially in the longitudinal direction 8 of the vehicle. In this case, the longitudinal member 7a is designed as a rear longitudinal member 7a with respect to a longitudinal direction 8 of the vehicle, which can also be referred to as the "rear longitudinal member". In this case, the longitudinal member 7a is arranged or formed on the outside of the body structure 2 with respect to a transverse direction 9 of the vehicle. Thus, the longitudinal member 7a, for example, limits the body structure 2 outwards in the transverse direction 9 of the vehicle. As shown in Figure 2, the longitudinal member 7a is designed as a longitudinal member 7a. Fig. 1 and Fig. As can be seen in Figure 2, the longitudinal member 7a is part of a floor assembly 10 of the body. In other words, the body structure 2 is designed as the floor assembly 10. Alternatively, the body structure 2 at least includes the floor assembly 10.

[0039] In this embodiment, the electrical energy storage device 3 is designed as an underfloor storage device 11. The electrical energy storage device 3 is, for example, arranged in a receiving space, which is, for example, at least partially formed by the body structure 2. The receiving space, and in particular the electrical energy storage device 3 arranged in the receiving space, extends in the vehicle's vertical direction 12, thus in this case under an interior space of the motor vehicle 1 or the body. The interior space 13 can also be referred to as the passenger compartment or passenger cell. Preferably, the interior space is at least partially formed by or bounded by the body structure 2, in particular by the body. Thus, in this case, the electrical energy storage device 3 is arranged in an external space 14, which in this case extends at least partially in the vehicle's vertical direction 12 under the interior space 13.The interior space 13 is preferably a dry room, whereas the exterior space 14 is in this case a wet room.

[0040] In order to optimize the design of the installation space of the motor vehicle 1, or rather the body, the cable receptacle 6, or the charging cable 4, runs at least partially through the longitudinal member 7a. This means that the cable receptacle 6 has at least a first length section 6a, which extends outside the longitudinal member 7a, and the cable receptacle 6 has at least a second length section 6b, which extends inside the longitudinal member 7a. Thus, the charging cable 4 extends outside the longitudinal member 7a in the first length section 6a and inside the longitudinal member 7a in the second length section 6b. As shown in Fig. 1 and Fig. As can be seen from section 2, the first length section 6a extends between the longitudinal beam 7a and the electrical energy storage device 3. Fig. Figure 2 thus illustrates the course of the charging line 4 from the receiving area for the electrical energy storage device 3 through the longitudinal beam 7a.

[0041] In the exemplary embodiment, the longitudinal member 7a has an opening 7b extending inwards in the transverse direction 9 of the vehicle, through which the charging line 4 can be inserted into the longitudinal member 7, in particular into a cavity extending within the longitudinal member 7a. Thus, the length sections 6a, 6b are connected to each other, for example, via the opening 7b, in particular directly. Therefore, the longitudinal member 7a can have the opening 7b, which is provided, for example, for threading, in particular threading in, the charging line 4. As in Fig. As shown in Figure 2, a side sill 15 is arranged on the longitudinal member 7, for example, extending outwards in the transverse direction 9 of the vehicle. The charging line 4 runs around the side sill 15.

[0042] In this embodiment, the connection point 5 is located on an upper surface of the electrical energy storage device 3, pointing upwards in the vehicle's vertical direction 12. This means that the charging cable 4 is electrically connected to the electrical energy storage device 3 on this upper surface. The charging cable 4 can thus be routed out of the electrical energy storage device 3 from above, in the vehicle's vertical direction 12. Routing the charging cable through the longitudinal member 7a is particularly advantageous, as the charging cable can then be located at least substantially at the same height as the longitudinal member 7a in the vehicle's vertical direction 12. This eliminates the need for the charging cable 4 to bypass the longitudinal member 7a.

[0043] In the exemplary embodiment, a wheel housing 16 adjoins the longitudinal member 7a, particularly at least indirectly or directly, to the rear in the longitudinal direction 8 of the vehicle, wherein the cable receiving area 6 is preferably formed partially by the wheel housing 16. This is shown in Fig. Figure 3 illustrates the body structure 2, or the motor vehicle 1, in a schematic and perspective partial view, particularly from a low angle. It shows the route of the charging line 4 from its entry into the longitudinal member 7a in the wheel housing 16 to a charging socket 17. Thus, the line receiving area 6 has a third length section 6c, which is partially formed by the wheel housing 16 and extends, for example, at least partially within the wheel housing 16. Therefore, the charging line 4 can be routed over the wheel housing 16, and in particular through the wheel housing 16, to the charging socket 17. Specifically, the charging line rests against at least one part of the wheel housing 16, preferably directly. The wheel housing 16 is designed as a rear wheel housing 16. This means that the wheel housing is intended for a rear wheel of the motor vehicle 1.

[0044] In the exemplary embodiment, the longitudinal member 7a has, for example, a second opening 7c, spaced apart from the opening 7b, for example in the longitudinal direction 8 of the vehicle and / or in the transverse direction 11 of the vehicle, through which the charging line 4, which extends, in particular at least partially, within the longitudinal member 7a, can be led out of the longitudinal member 7a or is led out, and in particular to the wheel housing 16. Thus, for example, the second and the third longitudinal sections 6b, 6c of the cable receiving area 6 are connected to each other via the second opening 7c, in particular directly. For example, the cavity opens into the surroundings of the longitudinal member 7a via the respective opening 7b, 7c on different sides of the longitudinal member 7a. The sides are, for example, facing away from each other in the transverse direction 9 of the vehicle.

[0045] As in Fig. Figure 3 illustrates that the charging line 4 is connected to the charging socket or charging pot 17 via a second connection point 18, in particular directly. Specifically, the charging line 4 extends between connection points 5 and 18, bypassing the interior 13.

[0046] For example, the charging cable 4 is designed in multiple sections. This means that the charging cable 4 has at least two separately designed cable sections which are connected to each other via a coupling point, in particular directly. The coupling point can also be referred to as a disconnect point. Preferably, the coupling point is arranged in the longitudinal direction of the charging cable 4 from the charging socket to the electrical energy storage device 3 between the charging socket and the longitudinal member 7a. Particularly preferably, the coupling point is arranged at the wheel arch 16. This allows one of the cable sections to be passed through the longitudinal member, in particular threaded through it, and then connected to the other cable section outside the longitudinal member. This prevents excessive deformation, in particular kinking, of the charging cable 4. This is particularly advantageous if the charging cable 4 is relatively rigid.This makes it particularly easy to install charging cable 4.

[0047] In this embodiment, the cable receptacle 6 or the charging cable 4 runs through a main load path in the rear of the body. In other words, at least one of the openings 7b, 7c is located in the main load path. The charging cable 4 can thus be threaded through the main load path. To increase the stiffness of the body structure 2, and in particular to prevent any weakening of the main load path caused by the cable receptacle or the charging cable 4 passing through it, the longitudinal member 7a can have a rib structure 19, which preferably has several ribs. The ribs preferably extend obliquely or perpendicularly to each other. For example, the longitudinal member 7a is designed as a die-cast component, in particular an aluminum die-cast component.

[0048] Fig. Figure 4 shows a schematic and perspective partial view of another body structure 2a of another motor vehicle 1a, and Fig. Figure 5 shows the other motor vehicle 1a, which is, for example, a conventional motor vehicle, in a schematic and perspective partial view. The other body structure 2a is, for example, a conventional body structure. In this case, Fig. 5 and Fig. Figure 6, for example, illustrates a conventional routing of the charging cable 4, in which the charging cable 4 runs through the interior 13. This is particularly well shown in Fig. It can be seen that the charging cable 4 runs through the interior 13 with visible overlaps with other components, which can result in a particularly complex routing of the charging cable 4 through the interior 13. This can lead to a particularly complicated arrangement of the charging cable 4 in the conventional motor vehicle 1a, which can result in a particularly high manufacturing effort for the conventional motor vehicle 1a. Furthermore, the routing of the charging cable 4 through the interior 13 can negatively affect the available space within the interior 13.

[0049] In contrast, the body structure 2 or the motor vehicle 1, which is particularly evident from Fig. As can be seen from Figures 1 to 3, the interior space 13, at least between the first connection point 5 and the longitudinal member 7a, preferably the wheel arch 16, and in particular the charging port 17 or the charging socket, must be kept clear of the charging line 4. This means that the cable receiving area 6, in particular the charging line 4, runs at least between the first connection point 5 and the longitudinal member 7a, in particular the wheel arch 16, for example the charging port 17 or the charging socket, bypassing the interior space 13. Fig. 2 shows the route of the charging line 4 below a service cover not shown, whereby the charging line 4 runs in the external space 14 (wet room).
