[0002] WO 2017 / 199655 A1 discloses an air outlet device for a vehicle having an electronic display, wherein the electronic display has a display surface for displaying information and an air outlet hole for air is also provided.

[0003] DE 10 2015 200 286 A1 further discloses a display unit for displaying image data on a display screen. Summary of the invention

[0004] The object of the present invention is to provide a ventilation device and a motor vehicle, with which the vehicle interior can be supplied with air in a particularly advantageous manner.

[0005] This object is achieved by a ventilation device having the features of claim 1 and a motor vehicle having the features of claim 10. Advantageous embodiments with suitable inventive developments are described in the dependent claims.

[0006] A first aspect of the invention relates to a ventilation device for a motor vehicle, preferably designed as a passenger car. The ventilation device has at least one electronic display device, which is also referred to as a display and has at least one display surface for displaying information, in particular for displaying information electrically or electronically. In particular, letters and / or symbols and / or images etc. can be displayed on the display surface in order to provide information to people, for example, who are staying in the interior of the motor vehicle.

[0007] The ventilation device also has an air distribution chamber that can be supplied with air, which is arranged on the back side of the display facing away from the display surface. That is, the automobile has the ventilation device and thus the display and the air distribution chamber in its finished state. The back side of the display is facing away from the interior in the longitudinal direction of the vehicle. For example, the back side points forward in the longitudinal direction of the vehicle. The ventilation device also has an air outlet connected to the edge area of ​​the display and through which the air from the air distribution chamber can flow, and the air outlet is preferably slit-shaped, that is, arranged as an air outlet slit. The slit can be not only continuous but also intermittent. Through the air outlet, the air flowing through the air outlet can be introduced into the interior of the automobile from the air distribution chamber. In other words, air can flow from the air distribution chamber through the air outlet and thus flow through the air outlet and thus flow into the interior of the automobile, whereby the interior is ventilated.

[0008] In order to now achieve a very advantageous supply of air to the interior, i.e. a very advantageous ventilation of the interior, the invention provides that the ventilation device has at least one air calming chamber which is at least partially, in particular mostly, fluidically separated from the air distribution chamber, the air calming chamber being arranged on a second back side of the air distribution chamber which faces away from the back side of the display. In other words, the back side of the display is also referred to as the first back side. The first back side, for example, faces the air distribution chamber and, for example, partially directly delimits the air distribution chamber, so that, for example, the air contained in the air distribution chamber or the air flowing through the air distribution chamber directly contacts the first back side of the display. Instead of direct contact, a partition layer or an air gap can be arranged between the air and the first back side.

[0009] Here, the air distribution chamber has, for example, a second back side facing away from the first back side. Here, the aforementioned air stabilization chamber is arranged on the second back side, which is at least partially, especially mostly, separated from the air distribution chamber fluid. The air stabilization chamber is connected to the air distribution chamber fluid through at least one through-hole, so that the air to be supplied to the inner room can be supplied to the air distribution chamber through the through-hole. This means that the air to be supplied to the inner room is first supplied to the air stabilization chamber, that is, it is passed into the air stabilization chamber. In the air stabilization chamber, the air that is to be passed into or has been passed into the air stabilization chamber can become stable. Then, the air can be guided from the air stabilization chamber into or flow into the air distribution chamber, wherein the air then flows from the air distribution chamber to and especially flows through the air outlet. Therefore, the air stabilization chamber is used, for example, to first stabilize the air and then supply the air to the air distribution chamber. As a result, the flow rate can be reduced and the pressure loss is thus reduced. As a result, the inner room can be ventilated particularly advantageously and particularly comfortably for people staying in the inner room.

[0010] In this case, the air outlet is at least partially directly delimited by an edge region of the display.

[0011] In order to be able to ventilate the interior in a structurally advantageous and thus highly advantageous manner, it is provided in an advantageous embodiment of the invention that the air distribution chamber extends in an air distribution level and the air smoothing chamber extends in an air smoothing level extending parallel to the air distribution level. The air distribution level is also referred to as the first level and the air smoothing level is also referred to as the second level. By the direction and arrangement of the air distribution chamber in the first level and the air smoothing chamber in the second level, a very flat and thus structurally advantageous ventilation device construction can be achieved in a direction perpendicular to these levels, in particular, so that the interior can be ventilated in a structurally advantageous and thus highly advantageous manner. In addition, a modular ventilation device structure can be presented as will be described below, so that, for example, the ventilation device can be adapted to different applications in a simple and particularly suitable manner. In particular, the ventilation device can be changed accordingly in a very simple manner and thus, for example, can be used for different vehicle derivatives. The invention in particular allows a sandwich structure of the ventilation device to be provided, so that, for example, the ventilation device can be installed or assembled particularly efficiently. In the sandwich structure, these levels are, for example, individual layers and / or cores, which are arranged, for example, between corresponding coverings. This makes it possible to produce a particularly simple, modular and therefore easily modifiable structure, so that a very advantageous ventilation of the interior can be achieved.

[0012] It has proven to be particularly advantageous if the display surface extends in a display level that extends parallel to the air distribution level and parallel to the air level. The display level is also referred to as the third level. This makes it possible to advantageously represent the layered or sandwich structure of the ventilation device, so that the interior can be ventilated in a particularly advantageous manner and in a particularly simple and space-saving manner.

[0013] In a particularly advantageous embodiment of the invention, the air distribution chamber and the air smoothing chamber are separated from each other at least partially, in particular for the most part, by a partition along the aforementioned direction extending perpendicularly to the air distribution plane and perpendicularly to the air smoothing plane, also referred to as the separation direction. The partition is preferably solid. In particular, the partition is inherently rigid and therefore dimensionally stable. Here, the partition has a through-opening, which is preferably designed as a through hole and therefore passes completely through the partition. In other words, the through-opening is formed in the partition and is simultaneously designed as a through hole. Preferably, the through-opening is completely surrounded by the partition, i.e., by the wall of the partition, along its circumference. The partition preferably extends at least for the most part, in particular for the most part, in a partition plane arranged between the air distribution plane and the air smoothing plane along the separation direction and extending parallel to the air distribution plane and parallel to the air smoothing plane, the partition plane also being referred to as the fourth plane. Since the partition extends at least for the most part in the partition plane, the partition is, for example, a plate-like or plate-shaped component, which is, for example, designed as a planar component. This allows a very advantageous modular and in particular sandwich-like structure to be achieved. The partition is, for example, a covering or coating of a sandwich structure for an air distribution chamber and / or an air smoothing chamber, and the sandwich structure is also referred to as a sandwich construction. The air distribution chamber is here, for example, arranged between a display, in particular the first back side of the display, and a partition, in particular the front side of the partition facing the first back side, in particular along a separation direction. Thus, for example, the air distribution chamber is in particular the first core of a sandwich structure, which is arranged along a separation direction between the display and the partition. Thus, for example, a display, which is preferably designed to be solid and / or inherently rigid, is another covering or coating for the air distribution chamber, where each covering or coating is a component of the sandwich structure. Thus, a particularly advantageous modular structure can be presented with a particularly advantageous sandwich construction of the ventilation device. Preferably, the display and the partition are constructed separately from each other and are at least indirectly connected to each other.

[0014] For example, a delimiting element is provided, which is spaced apart from the separator, for example, along the separation direction. In this case, the delimiting element is preferably solid and / or inherently rigid, i.e., stable in shape. The delimiting element is, for example, another third coating or covering of the sandwich structure, wherein the delimiting element is, for example, a covering or coating for an air calming chamber. In this case, for example, the air calming chamber is arranged along the separation direction between the separator, in particular the back side of the separator facing away from the front side of the separator, and the delimiting element, in particular the front side of the delimiting element facing the separator, so that, for example, the air calming chamber is the second core of the sandwich structure arranged between the separator and the delimiting element. The delimiting element preferably extends in this case within a delimiting plane, which is also referred to as a fifth plane and extends, for example, parallel to the first plane, parallel to the second plane and parallel to the third plane.

[0015] In order to be able to supply air to the inner room particularly advantageously and in particular in a manner that meets the requirements, it is provided in other embodiments of the invention that the air distribution chamber is divided into a plurality of side-by-side sub-chambers, wherein each sub-chamber is provided with at least one through-opening, through which the respective sub-chamber is fluidically connected to the air smoothing chamber and can be supplied with the air to be supplied to the inner room. The previous and following description of the aforementioned first through-opening can also be directly transferred to the other through-openings, and vice versa.

[0016] It has proven to be particularly advantageous here that, in order to divide the air distribution chamber, the subchambers are separated from one another along a dividing direction extending within the air distribution level by at least one preferably solid and / or inherently rigid dividing wall, wherein the subchambers are completely fluidically isolated from one another along the dividing direction by means of the dividing wall. Preferably, the dividing wall itself or the material of which it is composed is airtight. Alternatively or additionally, the dividing wall is formed, for example, in one piece with the partition. By dividing the air distribution chamber, the air can be directed in a targeted manner, in particular as required, so that the interior can be ventilated particularly advantageously.

[0017] Another embodiment is characterized in that the air distribution chamber and the air calming chamber extend at least over / occupies a large part of the display area behind the display, i.e., at least over a large part of the display area. That is, the air distribution chamber and the air calming chamber extend at least over more than half of the display area, in particular in the air distribution level and the air calming level. As a result, the air can be distributed very advantageously and evenly and thus can be fed into the interior, in particular at different locations.

[0018] In particular, it is conceivable that the ventilation device has a plurality of air outlets, and the above and below descriptions of the division of at least one air outlet can be transferred to the plurality of air outlets, and vice versa.

[0019] In order to be able to supply air to the inner room particularly advantageously through a plurality of air outlets that act as outflow outlets or air outflow outlets and, for example, are in the shape of air outlet slits, it is provided in another design of the present invention that the ventilation device has a fan / blower arranged outside the air distribution chamber and outside the air smoothing chamber, especially arranged in a box called an air conditioning box, by which the air to be supplied to the inner room can be conveyed and thus provided. Here, at least two duct members are provided, each of which has at least one or exactly one air duct through which the air to be supplied to the inner room can flow. Each air duct can be supplied with air provided by the fan at one end. The air conditioning box, for example, defines a receiving chamber, which can be flowed through by the air conveyed by the fan. For example, the fan is arranged in the receiving chamber and provides the air to be supplied to the inner room in the receiving chamber. Here, for example, each air duct is fluidly connected to the receiving chamber at one end, so that the air that at least partially flows through the receiving chamber and is conveyed by the fan can flow into the respective air duct at one end. As a result, the air flowing into the respective air duct at one end can flow through the air duct and thus flow through the respective duct member. At the other end, each air duct is connected to the air stabilization chamber fluid through its own supply port. In other words, the air duct leads to the air stabilization chamber at the other end through each supply port spaced apart from each other. The feature "the supply ports are spaced apart from each other, i.e., for example, spaced apart from each other in the fifth plane" should be understood in particular as that the supply ports are individual or separate openings, rather than, for example, a single large opening. Here, the air from the air duct can be passed into the air stabilization chamber via the supply port, whereby the air stabilization chamber can be supplied with air from the air duct. The supply port is formed, for example, in the delimiting member. Alternatively or additionally, the supply port is designed as a through hole that penetrates the delimiting member in particular completely. Each supply port is, for example, completely surrounded by the delimiting member along its circumference, in particular by the corresponding delimiting member wall preferably formed as a solid. Here, in particular, the feature "the supply ports are spaced apart from each other" can refer to a wall area where a delimiting member is provided between the supply ports, in particular along the spacing direction extending in the fifth plane. The above and following descriptions of the separator can also generally be transferred to the delimiting member, and vice versa. Thus, for example, the delimiting element is a plate-shaped or plate-like component which extends at least for the most part, in particular completely, within the fifth plane and is thus designed, for example, as a flat element.

[0020] In particular, the invention allows a particularly simple supply or ventilation of interior air, in particular through a number of flow outlets or air outlets designed as air outlet slits. In particular, a flexible positioning of the air duct that can deliver air from the fan to the air smoothing chamber can be achieved. Thus, for example, the structural space requirements of other additional components can be responded to as required. In particular, through the aforementioned modular structure, the ventilation device of the invention can be particularly simple and adapted to different structural space conditions. It is also possible to use a conventional air conditioning box with corresponding air outlets for central and side nozzles, also called air conditioning air outlets, to supply the air smoothing chamber with air to be supplied to the interior. The invention is based in particular on the following recognition: In common air conditioning devices of automobiles, air is delivered from the air conditioning box via one or more air conditioning air outlets to an air flow outlet, also called a nozzle, through which the air is finally delivered to the interior, also called the cabin. As a result, the interior air can be conditioned, for example. "Conducting air from the air conditioning box to the air flow outlet" is usually carried out by individual air ducts from each air outlet of the air conditioning box to the corresponding air flow outlet. In this case, one air outlet, also called side air nozzle, is installed in the interior on each side of the vehicle and 2-4 air outlets are arranged in the center of the interior, for example at or in the instrument panel and especially in its center.

[0021] A further background is that automobile displays are becoming larger and wider, especially in the transverse direction of the vehicle, and thus wider and perhaps covering the entire width of the automobile or the interior extending in the transverse direction of the vehicle. In order to still achieve very favorable interior ventilation and very favorable environmental conditions in the interior under this background, at least one gap or multiple gaps in the edge area of ​​the display, also called the edge, are used as air flow outlets, i.e. the aforementioned air outlets, to allow air to flow into the interior. The respective air outlets, which are preferably in the shape of a gap or constituted as air outlet gaps, are, for example, bounded on the one hand by the display or its edge area, and on the other hand by the interior components of the ventilation device or the automobile. The interior components can be constituted separately from the display and are therefore indirectly, especially directly, connected to the display. If the aforementioned classical structure is maintained when supplying air to the interior, i.e., each air nozzle, i.e., each air outlet gap uses an air duct to supply the air to be supplied to the interior via the respective air outlet gaps, then a large structural space requirement for the ventilation device is thereby caused. Now, this can be avoided by the present invention. The invention allows existing air ducts that have been used to supply air to the central and / or side nozzles to be sufficient to be able to supply air to at least one or preferably a plurality of air outlets of the ventilation device via the air smoothing chamber and the air distribution chamber in a very advantageous manner. It is particularly possible to connect the air outlet of the ventilation device according to the invention to a box, also referred to as an air distribution box, which is arranged in particular behind a display, whereby preferably a plurality of air outlets of the ventilation device can be supplied with air from the air distribution box in a space-saving manner. This results in a high degree of flexibility in the operation of the ventilation device as a whole.

[0022] The air distribution chamber and the air smoothing chamber form a chamber system which is particularly simple and in which the structural space can be advantageously supplied with air. The actual distribution or distribution of the air introduced into the chamber system to the preferably multiple air outlets of the ventilation device, which are in particular designed as air outlet slots, is carried out, for example, via the chamber system, in particular via the air distribution level, and not in advance via air ducts or pipes extending from the air smoothing level to the box, wherein the air pre-distribution has already taken place via the channels leading into the chambers defined by the partition walls. In this way, the structural space requirement, in particular behind the air smoothing level, can be kept small.

[0023] Overall, it can be seen that the air smoothing chamber is an additional chamber relative to the air distribution chamber, which serves to smooth the air and to arrange the duct element and thus its air duct in a particularly suitable and therefore flexible manner, i.e. to connect it to the air smoothing chamber in a fluidic manner. This makes it possible, for example, to respond to different installation space conditions and thus different vehicle variants as required and flexibly.

[0024] Finally, it has proven to be particularly advantageous if the respective supply openings are at least partially offset relative to the through-openings, in particular in the fifth level, thereby ensuring a particularly advantageous and pleasant ventilation of the interior.

[0025] A second aspect of the invention relates to a motor vehicle, preferably designed as a sedan, having at least one ventilation device, which is preferably a ventilation device according to the invention according to the first aspect of the invention. The ventilation device has at least one electronic display having at least one display surface for displaying information. The ventilation device also includes an air distribution chamber arranged on the back side of the display facing away from the display surface and which can be supplied with air. In addition, the ventilation device has at least one air outlet connected to the edge area of ​​the display and through which air from the air distribution chamber can flow, and the air flowing through the air outlet can be passed into the interior of the vehicle via the air outlet. The air outlet is at least partially directly bounded by the edge area of ​​the display.

[0026] In order to achieve a very advantageous ventilation of the interior, the invention provides that the ventilation device has at least one air stabilization chamber, which is arranged on the second back side of the air distribution chamber facing away from the back side of the display and is at least partially, especially mostly, fluidly isolated from the air distribution chamber, and is fluidly connected to the air distribution chamber via at least one through-hole, through which the air distribution chamber can be supplied with air to be supplied to the interior, especially from the air stabilization chamber. The advantages and advantageous designs of the first aspect of the invention should be regarded as the advantages and advantageous designs of the second aspect of the invention, and vice versa.

[0027] Further advantages, features and details of the invention are obtained from the following description of preferred embodiments and in conjunction with the figures. The features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the description of the figures and / or shown individually in the figures can be used not only in the respectively indicated combination, but also in other combinations or individually without exceeding the scope of the invention.

[0035] In the figures, identical or functionally identical components are provided with the same reference symbols.

[0036] Figure 1 A ventilation device 10 for a motor vehicle, which is preferably designed as a passenger car, is shown in a perspective front schematic view. This means that the motor vehicle, in its manufactured state, has a ventilation device 10 arranged in a motor vehicle interior 12. In this case, a dashboard 14 of the motor vehicle is provided in the interior 12, wherein the ventilation device 10 is, for example, placed or held or mounted on the dashboard 14. The ventilation device 10 has at least one electronic display 16, which is also referred to as a display screen and has at least one display surface 18. The display surface 18 extends within a first plane, which is also referred to as a display plane 70. Information can be displayed on the display 16, in particular on the display surface 18 and therefore in the display plane 70, in particular in the form of letters and / or symbols and / or graphics, in particular electrically or electronically. In particular, the display 16 has a width extending in the transverse direction of the vehicle, which is greater than 50% of the width of the interior 12 extending in the transverse direction of the vehicle. The transverse direction of the vehicle is here in Figure 1In particular, the width of the display 16, in particular the display surface 18, is greater than 50%, in particular greater than 70% and preferably greater than 80%, more preferably greater than 90% of the width of the interior 12. Figure 1 It can be seen in the figure that the ventilation device 10, in particular the display 16, has an opening 23, through which, for example, the steering column of the vehicle extends in the finished state of the vehicle. The opening 23 can also be omitted in a vehicle without a steering column, for example.

[0037] As combined Figure 2 As can be seen when viewed together, the display 16 has a rear side 22 facing away from the display surface 18 and thus also facing away from the interior 12. In particular, the rear side 22 faces away from the display surface 18 in a direction perpendicular to the display layer 70. At least one air distribution chamber 24 of the ventilation device 10 is arranged on the rear side 22. As will be described in more detail below, the air distribution chamber 24 can be supplied with air, which is to be or is to be conveyed into the interior 12 by means of the ventilation device 10. As can be seen from Figure 2 As can be seen in FIG. 1 , the air distribution chamber 24 extends parallel to the above-mentioned direction and at Figure 2 2 is directly bounded by the display 16, in particular the back side 22, in a first limiting direction indicated by the arrow 26. Thus, for example, the air contained in the air distribution chamber 24 or flowing through the air distribution chamber 24 directly contacts the back side 22. Alternatively, a partition layer or an air gap may also be provided between the air in the air distribution chamber 24 and the back side 22. The back side 22 is also referred to as a first back side.

[0038] In a direction extending parallel to the aforementioned direction, opposite to the first limiting direction 26 and in Figure 2 In the second limiting direction 28 indicated by the arrow 28, the air distribution chamber 24 is delimited by a partition 30, which is designed to be solid and at the same time inherently rigid or dimensionally stable. In particular, the air distribution chamber 24 is directly delimited in the second limiting direction 28 by a first front side 32 of the partition 30, where the front side 32 faces the first rear side 22 and thus the display 16. The air flowing through the air distribution chamber 24 or contained in the air distribution chamber 24 can therefore directly contact the front side 32.

[0039] In order to be able to ventilate the interior 12 very advantageously, the ventilation device 10 has at least one air calming chamber 36 arranged on the second back side 34 of the air distribution chamber 24 or the partition 30 facing away from the first back side 22, and the air calming chamber is at least partially, especially mostly, separated from the air distribution chamber 24 by fluid in a direction extending perpendicular to the first plane. Here, the air calming chamber 36 is separated from the air distribution chamber 24 at least partially, especially mostly, in this direction by the partition 30.

[0040] As a clear overview Figure 3As can be seen, the ventilation device 10 has a plurality of air outlets in the form of air outlet slits 25, which adjoin the edge region 27 of the display 16, in particular in the vehicle vertical direction upwards and / or in the vehicle vertical direction downwards and / or in the vehicle transverse direction to the left and / or in the vehicle transverse direction to the right and can be flowed through by air from the air distribution chamber 24. Thus, the air flowing through the air outlet slits 25 can be passed from the air distribution chamber 24 into the interior 12 through the air outlet slits 25. Each air outlet slit 25 is therefore an air outflow outlet referred to as an outflow opening, through which air is passed from the air distribution chamber 24 into the interior 12. Thus, the interior 12 is ventilated. The feature "each air outlet is designed as a respective air outlet slit 25" means in particular that the air outlet or air outlet slit 25 is a gap or slot, which has a longitudinal extension direction and therefore has a length that is significantly greater than the height or width, in particular in the first plane. In particular, the length of each air outlet slit 25 is at least twice the height or width.

[0041] The respective air outlet slot 25 is, for example, directly bounded on the one hand by the edge region 27 of the display 16, in particular the display surface 18. On the other hand, the respective air outlet slot 25 is, for example, directly bounded by the interior component 29, wherein, for example, the interior component 29 is spaced apart from the edge region 27 in the first level. Therefore, the respective air outlet slot 25 is arranged between the edge region 27 and the interior component 29, in particular in the display level 70.

[0042] If you can also Figure 3 As can be seen in the figure, the partition 30 has a plurality of through-hole-shaped through-openings 38, which completely penetrate the partition 30 in particular in this direction. Through the through-openings 38, the air stabilization chamber 36 is in fluid communication with the air distribution chamber 24. The air stabilization chamber 36 can be supplied with air to be supplied or supplied to the interior 12. Therefore, through the through-openings 38, the air to be supplied to the interior and the air first passed into the air stabilization chamber 36 can be passed from the air stabilization chamber 36 into the air distribution chamber 24, so that the air from the air stabilization chamber 36 to be supplied to the interior can be supplied or supplied to the air distribution chamber 24 through the through-openings 38. Here, the air stabilization chamber 36 is directly bounded by the partition 30, in particular by the second back side 34, in the first limiting direction 26, so that the air received in the air stabilization chamber 36 or flowing through the air stabilization chamber 36 directly contacts the second back side 34.

[0043] It can be clearly seen that the air distribution chamber 24 extends in an air distribution level 66, which is also referred to as the second level and extends parallel to the first level. The air calming chamber 36 extends in an air calming level 68, which is also referred to as the third level and extends parallel to the first level and parallel to the second level. Therefore, the aforementioned direction extending perpendicularly to the first level also extends perpendicularly to the second level and perpendicularly to the third level. The partition 30 extends in a partition level 72, which is also referred to as the fourth level and extends parallel to the first level, parallel to the second level and parallel to the third level. In particular, the partition 30 extends at least for the most part, in particular completely, in the fourth level, so that more than half of the partition 30 extends in the fourth level. The partition 30 is arranged here between the air distribution chamber 24 and the air calming chamber 36 along the aforementioned direction extending also perpendicularly to the fourth level. Since the through-opening 38 is formed in the partition 30, the through-opening 38 also extends in the fourth level. The respective through-opening 38 has a through-opening along which air can flow from the air smoothing chamber 36 through the respective through-opening 38 and thus into the air distribution chamber 24. The through-direction runs parallel to the aforementioned direction and thus perpendicular to the fourth plane.

[0044] Finally, the ventilation device 10 includes a Figure 2 The delimiting member 40 can be clearly seen in the figure, which is spaced apart from the dividing member 30 along this direction. Here, the air calming chamber 36 is delimited directly by the delimiting member 40, in particular the second front side 42 of the delimiting member 40, in the second limiting direction, so that the air contained in the air calming chamber 36 or flowing through the air calming chamber 36 directly contacts the delimiting member 40, in particular its second front side 42. The second front side 42 here faces the second back side 34, and therefore the front side 42 faces the dividing member 30. The dividing member 30 and / or the delimiting member 40 are solid or inherently rigid. The display 16 is preferably also inherently rigid. The display 16, the dividing member 30 and the delimiting member 40 are preferably components that are constructed separately from each other and are at least indirectly connected to each other, and they can be spaced apart from each other in pairs in particular along this direction. As a result, as can be seen particularly clearly from Figure 2As can be seen in the figure, a sandwich structure, i.e. a sandwich construction of the ventilation device 10, is provided. The sandwich structure comprises a display 16 as a first cover or layer, in particular a first back side 22, a partition 30 as a second cover or layer, and a delimiting member 40 as a third cover or layer. Here, the air distribution chamber 24 is the first core or first core layer arranged between the display 16 and the partition 30 along this direction. Therefore, the display 16 and the partition 30 are the coverings or surfaces for the first core. The air calming chamber 36 is the second core or second core layer of the sandwich structure, wherein the partition 30 and the delimiting member 40 are the coverings or surfaces for the second core. Through the sandwich structure, a particularly flat structure can be provided, in particular, along this direction. In addition, a particularly modular structure can be provided thereby, so that the ventilation device 10 can be very flexibly and in a manner that meets the requirements to adapt to different structural space conditions, in particular behind the display 16.

[0045] Figure 3 A first embodiment of the ventilation device 10 is shown. In the first embodiment, a single-chamber system is provided with respect to the air distribution chamber 24. In this case, the air distribution chamber 24 is designed as exactly one large continuous chamber, which is not divided into a plurality of subchambers in the second level, i.e. along a dividing direction extending in the second level 66.

[0046] In contrast, Figure 4 A second embodiment is shown. In the second embodiment, the air distribution chamber 24 is divided into a plurality of sub-chambers 44a-d arranged side by side in the second plane 66, in particular in the second plane 66 and therefore along the aforementioned dividing direction extending in the second plane 66. Here, the air distribution chamber 24 is divided into sub-chambers 44a-d in the second plane 66 by respective dividing walls 46a-c, so that the respective dividing walls 46a-c are arranged between the respective sub-chambers 44a-d along the dividing direction. The dividing walls 46a-c do not allow the air located in the air distribution chamber 24 to pass through, so that the sub-chambers 44a-d are completely fluidically separated from each other by the dividing walls 46a-c along the dividing direction. This means in particular that the air contained in the air distribution chamber 24 cannot flow back and forth between the sub-chambers 44a-d in the air distribution chamber 24, i.e. cannot overflow.

[0047] Here, each subchamber 44a-d is provided with at least one through-opening 38. Subchamber 44a is assigned two through-openings 38, through which subchamber 44a is in fluid communication with air stabilization chamber 36. The respective subchamber 44b or 44c is assigned exactly one respective through-opening 38, through which the respective subchamber 44b or 44c is in fluid communication with air stabilization chamber 36. Subchamber 44d is assigned two through-openings 38, through which subchamber 44d is in fluid communication with air stabilization chamber 36.

[0048] You can also Figure 1 and Figure 4 As can be seen in FIG. 6 , the display 16, in particular the display surface 18, has a first surface or a first area. The air distribution chamber 24 has a second surface or a second area in the air distribution level 66, and the air smoothing chamber 36 has a third surface or a third area in the air smoothing level 68, wherein the second surface covers a large part of the first surface, and the third surface in turn covers a large part of the second surface. Alternatively or additionally, the air distribution chamber 24 has a second width in the air distribution level 66 extending in the transverse direction of the vehicle, and the air smoothing chamber 36 has a third width in the air smoothing level 68 extending in the transverse direction of the vehicle. The first width of the display 16 and in particular the display surface 18 extending in the transverse direction of the vehicle is also referred to as the first width. The third width is, for example, greater than 50% of the first width.

[0049] In addition, it can be clearly seen from Figure 3 and Figure 4 As can be seen in the figure, the respective air outlet slots 25 are assigned corresponding adjusting members 48. By means of the adjusting members 48, the outflow direction of the air flowing through the respective air outlet slots 25 into the inner room can be adjusted, that is, changed. For this purpose, the respective adjusting members 48 can be adjusted as follows: Figure 6 6 is a flexible or elastically deformable element which is mounted in a manner that it can swing in the support 62 and can move, in particular longitudinally move, in the support 64. By means of the longitudinal movement of the adjusting element 48 in the support 64, different bending conditions of the adjusting element 48 can be set, whereby the outflow direction can be adjusted. In particular, the adjusting element 48 can be moved in the support 64 along the direction of movement. The direction of movement preferably runs parallel to the partition plane 72 (fourth plane). In particular, the respective adjusting element 48 is arranged between the partition 30 and the display 16, in particular in the air distribution chamber 24, in particular along the aforementioned direction.

[0050] Can be obtained from Figure 5 As can be seen in FIG. 1 , the ventilation device 10 has Figure 5 2 and 3. The fan 50 is particularly schematically shown in the figure. The fan 50 is arranged outside the air distribution chamber 24 and outside the air smoothing chamber 36. The fan 50 is particularly arranged in a box 52, which is also called an air distribution box or an air conditioning box. With the help of the fan 50, the air to be conveyed into the interior 12 is conveyed or can be conveyed. Thus, for example, the air to be conveyed into the interior 12 can flow through at least a part of the box 52. The box 52, for example, defines a receiving chamber 54, in which the fan 50 is arranged. Thus, the air to be conveyed into the interior 12 and conveyed by the fan 50 can flow through at least a part of the receiving chamber 52.

[0051] Here, the delimiting element 40 preferably extends within a delimiting level 74, which is also referred to as the fifth level. Figure 5As can be seen in the figure, the delimiting member 40 has a supply opening 56 in the form of a through hole, which completely penetrates the delimiting member 40 and extends in the delimiting level 74 (fifth level). Therefore, each supply opening 56 has a through direction, which runs perpendicular to the fifth level. Along the through direction of each supply opening 56, the air to be supplied to the interior room can flow through the respective supply opening 56.

[0052] Each supply opening 56 is, for example, assigned with a respective duct member 58, which has a respective air duct 60 through which the air to be supplied to the inner chamber 12 can flow. Each air duct 60 is fluidly connected to the accommodating chamber 54 at one end, so that the air delivered by the fan 50 is passed or can be passed into the respective air duct 60 at one end. At the other end, each air duct 60 passes into the air stabilization chamber 36 through the respective supply opening 56. In other words, each air duct 60 is fluidly connected to the air stabilization chamber 36 via the respective supply opening 56 at the other end. Therefore, the air input by the fan 50 can flow into the air duct 60 at one end. Therefore, the air flowing into the air duct 60 at one end can flow through the air duct 60 and then the duct member 58. At the other end, the air flowing into the air duct 60 can flow out of the air duct 60 and thus flow into the air stabilization chamber 36. With the help of the air stabilization chamber 36, the air flowing into the air stabilization chamber 36 first becomes stable. Subsequently, the air can flow from the air stabilization chamber 36 into the air distribution chamber 24. Then, by means of the air distribution chamber 24 , the air flowing into the air distribution chamber 24 is distributed to, in particular distributed to, the air outlet slots 25 .

[0053] Since exactly four subchambers 44a-d are provided in the second embodiment, a four-chamber system is provided in the second embodiment with respect to the air distribution chamber 24. The number of air outlet slots 25, also referred to as nozzles, for supplying air into the interior 12 can be freely designed and can depend in particular on the control principle for varying the respective flow cross section. The control principle can also be designed variably or as required.

[0054] For example, from Figure 4 As can be seen in the figure, the supply opening 56 is at least partially offset relative to the through-opening 38 in the delimiting plane 74. By using the air distribution chamber 24 and the air leveling chamber 36, a plurality of air outlet slots 25 can be supplied in a very advantageous manner and in particular at least substantially uniformly with the air to be supplied to the interior 12, specifically by means of only a few duct elements 58. This makes it possible, for example, to keep the space requirement of the ventilation device 10 behind the delimiting element 40 small. In addition, the air in the box 52 can be supplied to the air leveling chamber 36 as required, so that, for example, the ventilation device 10 can be adapted as required and flexibly to different construction space conditions.

[0055] The display surface and the cover surface are also referred to as surfaces, wherein the surfaces can extend parallel to one another, but do not necessarily have to extend parallel to one another. The surfaces can extend in particular slightly inclined to one another. In other words, at least two of the surfaces can extend in particular slightly inclined to one another. The planes do not necessarily have to extend parallel to one another, but can in particular extend slightly inclined to one another.
