Description

[0001] The present invention relates to an air outlet with diamond-shaped air guides according to the preamble of claim 1 and a motor vehicle provided therewith according to claim 9.

[0002] Air outlets with air outlet grilles of various geometries are known from DE 10 2017 009 422 A1, DE 38 37 916 A1, DE 10 2015 001 477 A1, DE 19 29 827 A, DE 10 2019 112 341 A1, DE 102 19 053 A1 and DE 10 2020 103 630 A1.

[0003] Air outlets are known from DE 10 2018 104 043 A1 and KR 10 2021 0 108 507 A, respectively, with - a housing that has an upstream air inlet area and, viewed in the longitudinal direction of the housing, a downstream air outlet area; - a first air outlet grille located downstream in the air outlet area, which is aligned in a first virtual plane orthogonal to the longitudinal direction and extends in a transverse direction as well as in a vertical direction of the housing, wherein the first air outlet grille has a number of first air outlet openings; - a second air outlet grille located in the air outlet area, adjacent upstream to the first air outlet grille, which extends in a second virtual plane parallel to the first plane, wherein the second air outlet grille has a number of second air outlet openings; - wherein the second air outlet grille is designed to be translationally movable relative to the first air outlet grille in the second plane in order to align the first air outlet openings and the second air outlet openings at least partially with each other in order to influence an outflow direction of air exiting the housing.

[0004] The object of the present invention is to design a generic air outlet in a functionally and aesthetically pleasing manner.

[0005] This problem is solved by an air outlet having the features of claim 1.

[0006] Therefore, this task is solved by an air outlet, with - a housing that has an upstream air inlet area and, viewed in the longitudinal direction of the housing, a downstream air outlet area; - a first air outlet grille located downstream in the air outlet area, which is aligned in a first virtual plane orthogonal to the longitudinal direction and extends in a transverse direction as well as in a vertical direction of the housing, wherein the first air outlet grille has a number of first air outlet openings; - a second air outlet grille located in the air outlet area, adjacent upstream to the first air outlet grille, which extends in a second virtual plane parallel to the first plane, wherein the second air outlet grille has a number of second air outlet openings; - wherein the second air outlet grille is designed to be translationally movable relative to the first air outlet grille in the second plane in order to align the first air outlet openings and the second air outlet openings at least partially with each other in order to influence an outflow direction of air exiting the housing.

[0007] The air outlet according to the invention is characterized by the fact that - the first air outlet grille has a number of first air guide elements spaced apart from each other to form the first air outlet openings, which, in a virtual plane spanned in the longitudinal and transverse direction of the housing, each have a rhomboid or kite-shaped cross-section, - the second air outlet grille has a number of second air guide elements spaced apart from each other to form the second air outlet openings, which, in the virtual plane spanned in the longitudinal and transverse direction of the housing, each have a rhomboid or kite-shaped cross-section.

[0008] In other words, an air outlet is created with a first, stationary air outlet grille, next to which a second, movable air outlet grille is arranged upstream. The stationary air outlet grille is located downstream in a region of the air outlet from which the air flowing through it exits the housing, particularly into the interior of a motor vehicle. Due to the special design of the air guide elements with rhomboid or kite-shaped cross-sectional areas, the air outlet not only has a particularly aesthetic appearance, but also—due to their comparatively large dimensions and extent in the direction of flow—relatively good airflow control. A particularly positive effect is that a simplified adjustment mechanism can be used for the air outlet grilles of the air outlet according to the invention.

[0009] As previously disclosed, the air outlet according to the invention comprises a first, stationary air outlet grille with diamond-shaped or kite-shaped cross-sectional areas, and a second air outlet grille, which is translationally displaceable, particularly in the transverse direction of the air outlet, and also has diamond-shaped or kite-shaped cross-sectional areas. By appropriately moving or adjusting the second air outlet grille relative to the first air outlet grille, the direction of the air flowing from the air outlet is effectively influenced.

[0010] According to a preferred embodiment, it is provided that - a first air guide element has a first flank with an upstream second flank adjoining it, as well as a third, downstream flank formed in a mirror image on a virtual intermediate plane of the first air guide element spanned in the longitudinal and vertical direction, with an upstream fourth flank adjoining it; - a second air guide element has a first flank with an upstream second flank adjoining it, and a third, downstream flank formed in a mirror image on a virtual intermediate plane of the second air guide element spanned in the longitudinal and vertical direction, with an upstream fourth flank adjoining it; wherein - the flanks of the first air guide element and the flanks of the second air guide element are spaced apart from each other in a first operating state; and - the respective second flanks of the first air guide element and the third flanks of the second air guide element are adjacent to each other in a second operating state different from the first operating state; and - the respective fourth flanks of the first air guide element and the first flanks of the second air guide element are adjacent to each other in a third operating state different from the first operating state and the second operating state.

[0011] If the four aforementioned flanks are of equal length, the cross-sectional area is rhomboid in shape. However, if the first and third flanks are of equal length, and the second and fourth flanks are of equal length but different lengths than the first and third flanks, the resulting cross-sectional area of ​​the air guide element is kite-shaped.

[0012] The diamond-shaped or kite-shaped cross-sectional design of the cross-sectional surfaces results in three operating states being possible for the air outlet according to the invention: In the first operating state, the flanks of the first air guide element and the flanks of the second air guide element are spaced apart. In this case, the outflowing air cannot leave the air outlet with any significant deflection.

[0013] In a second operating state, the respective second flanks of the first air guide element and the third flanks of the second air guide element are adjacent to each other. Particularly advantageously, these adjacent flanks are in contact with one another. In this operating state, the outflowing air can leave the air outlet in a second direction, deflected relative to the first air outflow direction.

[0014] In a third operating state, the respective fourth flanks of the first air guide element and the first flanks of the second air guide element are adjacent to each other. Particularly advantageously, these adjacent flanks are in contact with one another. In this operating state, the outflowing air can leave the air outlet in a third deflected direction.

[0015] According to a preferred embodiment, it is provided that - in the air outlet area there is a third air outlet grille adjacent upstream to the second air outlet grille, which extends in a third virtual plane parallel to the second plane, wherein the third air outlet grille has a number of third air outlet openings; - the third air outlet grille is designed to be translationally movable relative to the second air outlet grille in the third virtual plane in order to align the third air outlet openings and the second air outlet openings at least partially with each other in order to influence the outflow direction of air exiting the housing; - the third air outlet grille has a number of third air guide elements spaced apart from each other to form the third air outlet openings, which, in a virtual plane spanned in the longitudinal and transverse direction of the housing, each have a rhomboid or kite-shaped cross-section; wherein - the third air guide element has a first flank with an upstream second flank adjoining it, and a third, downstream flank formed in a mirror image on a virtual intermediate plane of the third air guide element spanned in the longitudinal and vertical direction, with an upstream fourth flank adjoining it; and wherein - the flanks of the second air guide element and the flanks of the third air guide element are spaced apart from each other in the first operating state; and - the respective second flanks of the second air guide element and the third flanks of the third air guide element are adjacent to each other in the second operating state; and - the respective fourth flanks of the second air guide element and the first flanks of the third air guide element are adjacent to each other in the third operating state.

[0016] In other words, the depth of the air outlet grilles located in the housing is increased by a further adjustable air outlet grille plane, thus further improving the flow direction of the air flowing from the air outlet according to the invention. The desired aesthetic appearance of the air outlet is advantageously preserved.

[0017] If the four aforementioned flanks are of equal length, the cross-sectional area is rhomboid in shape. However, if the first and third flanks are of equal length, and the second and fourth flanks are of equal length but different lengths than the first and third flanks, the resulting cross-sectional area of ​​the air guide element is kite-shaped.

[0018] The diamond-shaped or kite-shaped cross-sectional design of the cross-sectional surfaces results, even in this preferred embodiment, in three operating states that can be set for the air outlet according to the invention: In a first operating state, the flanks of the first air guide element, the flanks of the second air guide element, and the flanks of the third air guide element are spaced apart from each other. In this case, the outflowing air cannot leave the air outlet with any significant deflection.

[0019] In a second operating state, the respective second flanks of the first air guide element and the third flanks of the second air guide element, and the respective second flanks of the second air guide element and the third flanks of the third air guide element, are adjacent to each other. Particularly advantageously, these adjacent flanks are in contact with one another. In this operating state, the outflowing air can leave the air outlet in a second direction, deflected relative to the first air outflow direction.

[0020] In a third operating state, the respective fourth flanks of the first air guide element and the first flanks of the second air guide element, as well as the respective fourth flanks of the second air guide element and the first flanks of the third air guide element, are adjacent to each other. Particularly advantageously, these adjacent flanks are in contact with one another. In this operating state, the outflowing air can leave the air outlet in a third deflected direction.

[0021] According to another preferred embodiment, it is provided that - in the air outlet area there is a fourth air outlet grille adjacent upstream to the third air outlet grille, which extends in a fourth virtual plane parallel to the third plane, wherein the fourth air outlet grille has a number of fourth air outlet openings; - the fourth air outlet grille is designed to be translationally movable relative to the third air outlet grille in the fourth virtual plane in order to align the fourth air outlet openings and the third air outlet openings at least partially with each other in order to influence the outflow direction of air exiting the housing; - the fourth air outlet grille has a number of fourth air guide elements spaced apart from each other to form the fourth air outlet openings, which, in a virtual plane spanned in the longitudinal and transverse direction of the housing, each have a rhomboid or kite-shaped cross-section; wherein - the fourth air guide element has a first flank with an upstream second flank adjoining it, and a third, downstream flank formed in a mirror image on a virtual intermediate plane of the fourth air guide element spanned in the longitudinal and vertical direction, with an upstream fourth flank adjoining it; and wherein - the flanks of the third air guide element and the flanks of the fourth air guide element are spaced apart from each other in the first operating state; and - the respective second flanks of the third air guide element and the third flanks of the fourth air guide element are adjacent to each other in the second operating state; and - the respective fourth flanks of the third air guide element and the first flanks of the fourth air guide element are adjacent to each other in the third operating state.

[0022] As previously disclosed, the air guide elements have rhomboid or kite-shaped cross-sectional areas. A virtual plane, extending essentially longitudinally and transversely to the housing, is chosen as the reference plane for the cross-sectional areas. According to a particularly preferred embodiment, the pointed ends, i.e., the junction area of ​​the second and fourth flanks, of the disclosed air guide elements are oriented into the airflow.

[0023] If the four aforementioned flanks are of equal length, the cross-sectional area is rhomboid in shape. However, if the first and third flanks are of equal length, and the second and fourth flanks are of equal length but different lengths than the first and third flanks, the resulting cross-sectional area of ​​the air guide element is kite-shaped.

[0024] The diamond-shaped or kite-shaped cross-sectional design of the cross-sectional surfaces results, even in this preferred embodiment, in three operating states that can be set for the air outlet according to the invention: In a first operating state, the flanks of the first air guide element, the flanks of the second air guide element, the flanks of the third air guide element, and the flanks of the fourth air guide element are spaced apart from each other. In this case, the outflowing air cannot leave the air outlet with any significant deflection.

[0025] In a second operating state, the respective second flanks of the first air guide element and the third flanks of the second air guide element, the respective second flanks of the second air guide element and the respective third flanks of the third air guide element, and the respective second flanks of the third air guide element and the respective third flanks of the fourth air guide element are adjacent to one another. It is particularly advantageous that these adjacent flanks abut each other. In this operating state, the outflowing air can leave the air outlet in a second direction, deflected relative to the first air outflow direction.

[0026] In a third operating state, the respective fourth flanks of the first air guide element and the respective first flanks of the second air guide element, the respective fourth flanks of the second air guide element and the respective first flanks of the third air guide element, as well as the respective fourth flanks of the third air guide element, are adjacent to each other and to the respective first flanks of the fourth air guide element. It is particularly advantageous that these adjacent flanks abut each other. In this operating state, the outflowing air can leave the air outlet in a third deflected direction.

[0027] It should be noted that, viewed in the vertical direction of an air outlet grille, not only one row of air guide elements may be provided, but also two or more rows of air guide elements. In particular, it may be provided that two rows of air guide elements are arranged one above the other in the first, stationary air outlet grille, as well as in the second, movable air outlet grille and any further air outlet grilles. Alternatively, it may be provided that two rows of air guide elements are arranged one above the other in the first, stationary air outlet grille, three rows of air guide elements are arranged one above the other in the second, movable air outlet grille located downstream, and four rows of air guide elements are arranged one above the other in a third, movable air outlet grille located downstream.

[0028] According to a preferred embodiment, the air guide elements are formed as a flat surface in a plane parallel to the first plane. This portion of the air guide elements is preferably located on the downstream side of the first air outlet grille, thereby creating a special optical effect for an observer of the air outlet.

[0029] According to a preferred embodiment, the air outlet grilles are operatively connected to a handle pivotally mounted orthogonally to the longitudinal and transverse directions of the housing. This handle is configured to adjust each air outlet grille, with the exception of the fixed first air outlet grille, by the same angle. This advantageously enables uniform adjustment of the air guides.

[0030] As already described, the present air diffuser offers a particularly appealing aesthetic. This is further enhanced if at least one light source, in particular an LED or OLED, is provided. The at least one light source is located, in particular, within the housing and emits light towards the air guide elements. Advantageously, at least one air guide element is designed to be at least partially transparent, translucent, or light-reflecting, so that the light emitted by the light source can be reflected, refracted, or otherwise altered depending on the geometric design, color, or other characteristics of the air guide element.

[0031] The aforementioned problem is also solved by a motor vehicle according to claim 9. The aforementioned advantages apply accordingly.

[0032] The following is a detailed, non-prejudicative, and in particular limiting, description of exemplary embodiments of the present invention with reference to the accompanying figures, which are not to scale. Identical elements are designated with identical reference numerals unless otherwise indicated. Fig. Figure 1 is a perspective view of an air outlet according to the invention. Fig. 2A shows an air outlet according to the invention, located in a first operating position, in a horizontal section. Fig. 2B is an enlarged view of a detail of the Fig. 2A. Fig. 3A represents the air outlet of the Fig. 2A represents a second operating position. Fig. 3B is an enlarged view of a detail of the Fig. 3A. Fig. 4 shows the air outlet of the Fig. 1 in a partially cropped view in a third operating position.

[0033] In Fig. Figure 1 is a symbolic representation of a motor vehicle 1 with an air outlet 5. The air outlet 5 can be located at any suitable point on the motor vehicle 1, e.g., in an instrument panel, center console, or side panel (not shown here). The air outlet 5 has a housing 10, which in the embodiment shown here consists of a lower shell 15 and an upper shell 20. The air outlet 5 is located in the Fig. The part of the housing 10 shown on the right is operatively connected to a ventilation or air conditioning system of the motor vehicle 1 (not shown here). This side thus forms an upstream air inlet side or an air inlet area 25 of the air outlet 5, as symbolized by the arrow representing the inlet air 30.

[0034] For better spatial orientation, in the Fig. 1 a Cartesian coordinate system is introduced, whose x-axis runs essentially in the longitudinal direction, whose y-axis runs essentially in the transverse direction and whose z-axis runs essentially in the vertical direction of the motor vehicle 1.

[0035] Downstream, at which in the Fig. At its left end, the air outlet 5 has an air outlet area 35 from which the incoming air 30 can flow out into a vehicle interior 40, which is represented symbolically here. Within the air outlet area 35, a first air outlet grille 45 and a second air outlet grille 50 located upstream of it are visible. Each of these grilles comprises a number of air guide elements 55, of which only a few are labeled for clarity. The first air outlet grille 45 is oriented orthogonally to the longitudinal direction x and extends in a first virtual plane E1, which can also be referred to as the yz plane. The second air outlet grille 50 is also oriented orthogonally to the longitudinal direction x and extends in a second virtual plane E2, which, according to the present embodiment, is parallel to the first plane E1 but upstream of it.

[0036] The first air outlet grille 45 is fixedly mounted in the housing 10. In contrast, the second air outlet grille 50 is translationally movable in the second plane E2. Specifically, the second air outlet grille 50 is slidably mounted in the housing 10 in the transverse direction y, and movement of the second air outlet grille 50 can be effected via a handle 60 operatively connected to the second air outlet grille 50. The handle 60 has an axis 65 extending in the vertical direction z, which in turn is rotatably mounted in the housing 10 (symbolized by the double arrow I). At one end, the axis 65 is operatively connected to the second grille 50.

[0037] At the other end, the axis 65 is provided with a gear 70, which is guided around the axis 65 by a cam guide 75 located on the upper surface of the upper shell 20. When adjusted, the gear 70 meshes with a gear (not shown) of a mechanism (also not shown) such that its movement around the axis 65 results in a translational movement of the second air outlet grille 50.

[0038] By means of a further handling 80, a person in this Fig. 1 not shown, but in Fig. The air guide 85 shown in Figure 4 is pivoted about an axis 90 extending in the transverse direction y and mounted in the housing 10 (symbolized by the double arrow II). For this purpose, a gear 95 is attached to the axis 90, which meshes with a gear (not shown) of a mechanism (also not shown) such that its movement about the axis 90 results in a rotational movement of the air guide 85.

[0039] In Fig. Figure 2A shows a simplified horizontal section through an air outlet 5 according to the invention. As can be seen, the lower shell 15 contains not only a first, stationary air outlet grille 45 and a second air outlet grille 50, but also a third air outlet grille 100 and a fourth air outlet grille 105 located upstream of the second air outlet grille 50. The third air outlet grille 100 extends in a third plane E3, which is parallel to the first two planes E1 and E2. The fourth air outlet grille 105 extends in a fourth plane E4, which is parallel to the first plane E1 through the third plane E3. The second air outlet grille 50, the third air outlet grille 100 and the fourth air outlet grille 105 are each slidably mounted in the housing 10 on rails 110 extending in its transverse direction y.Therefore, the aforementioned air outlet grilles 50, 100 and 105 can be moved back and forth within the housing 10 in the transverse direction y for the purpose of adjustment.

[0040] As in Fig. As can be seen in Figure 2A, the air guide elements 55 of a single air outlet grille 45, 50, 100, and 105 are spaced apart from each other in the transverse direction y to form air outlet openings. Thus, the first air outlet grille 45 contains the first air outlet openings 115, the second air outlet grille 50 contains the second air outlet openings 120, the third air outlet grille 100 contains the third air outlet openings 125, and the fourth air outlet grille 105 contains the fourth air outlet openings 130, of which only a few are labeled with reference symbols for the sake of clarity.

[0041] Again Fig. As can be further seen from section 2A, the air guide elements 55 of the first air outlet grille 45, viewed in the longitudinal direction x, are aligned in line or flush with the air guide elements 55 of the third air outlet grille 100. The air guide elements 55 of the second air outlet grille 50, viewed in the longitudinal direction x, are aligned in line or flush with the air guide elements 55 of the fourth air outlet grille 105. Furthermore, the air guide elements 55 of the first air outlet grille 45 or third air outlet grille 100 and of the second air outlet grille 50 or fourth air outlet grille 105 are spaced apart from each other in the transverse direction y such that the incoming air 30 flowing into the air outlet 5 leaves it as essentially longitudinal air 135 flowing out through the air outlet grilles 45, 50, 100 and 105 into the vehicle interior 40, as symbolized by the arrows.This position of the aforementioned elements shall be designated as the first operating position. It is understood that the output air 135 flows out across the entire width of the air outlet 5.

[0042] Out of Fig. Figure 2A shows that the air guide elements 55 in the xy-plane, which will subsequently be referred to as plane E5, have a substantially rhomboid cross-section. To illustrate this, a section A1 is shown in the Fig. 2A in Fig. Figure 2B shows an enlarged view, in which each air guide element 55 of the first air outlet grille 45, the second air outlet grille 50, the third air outlet grille 100 and the fourth air outlet grille (in the Fig. 2B (from bottom to top) are shown. Each of the air guide elements 55 has a first flank 140 with an upstream second flank 145 adjoining it, as well as a third flank 150 mirrored on a virtual xz-mid plane spanning in the longitudinal x and vertical z direction (hereinafter also referred to as plane E6) of the air guide element 55, with an upstream fourth flank 155 adjoining it. For the sake of clarity, in Fig. 2B only shows an xz-mid plane or plane E6.

[0043] The in Fig. 2A, the air outlet 5 shown is in Fig. 3A is now shown in a different, second operating position. In this position, the air guide elements 55 of the second air outlet grille 50, the third air outlet grille 100, and the fourth air outlet grille 105 are translationally offset such that, together with the air guide elements 55 of the first air outlet grille 45, they form a wall inclined in the transverse direction y when viewed in the vertical direction z and extending in the xz-plane. A defined arrangement of the air guide elements 55 is required for this, which is particularly evident from the illustration in Fig. This is evident from section A2 shown in Figure 3B. As can be seen, the second flank 145 of the first air outlet grille 45 and the third flank 150 of the second air guide grille 50 are positioned adjacent to each other. The second flank 145 of the second air outlet grille 50 and the third flank 150 of the third air guide grille 100 are also positioned adjacent to each other. Finally, the second flank 145 of the third air outlet grille 100 is positioned adjacent to the third flank 150 of the second air guide grille 105. If, as in the Fig. 3A and Fig. As shown in Figure 3B, where the respective adjacent flanks 145, 150 are aligned side by side in the area of ​​their respective mean lengths, a deflection of the output air 135 results according to the one shown in Figure 3B. Fig. 3A shows the direction. However, the deflection of the output air 135 can also be adjusted differently by aligning the respective adjacent flanks 145, 150 not in the area of ​​their respective mean length, but possibly with a shorter or longer overlap area.

[0044] In Fig. 4 is the one already mentioned with reference to Fig. The air outlets 5 described in section 1 are shown in a partially cropped perspective view. Unlike in the Fig. 2A to 3B is owned by the in Fig. The four air outlets shown in the illustration consist of only a first air outlet grille 45, a second air outlet grille 50, and a third air outlet grille 100. A fourth air outlet grille 105 is not present in this embodiment but could easily be provided. Otherwise, the respective design of the aforementioned air outlet grilles 45, 50, and 100 corresponds to that described previously. The third air outlet grille 100 extends in a third plane E3, which is parallel to the first two planes E1 and E2.

[0045] As you can see, the one in Fig. 4 Air outlets 5 shown in a third operating state, in which the output air 135 is now directed into a different environment than the one in the Fig. 2A and Fig. 3A direction of outflow. For this purpose, the second air outlet grille 50 and the third air outlet grille 100 are aligned relative to the first air outlet grille 45 such that the fourth flanks 155 of the air guide element 55 of the first air outlet grille 45 and the first flanks 140 of the second air outlet grille 50 are adjacent to each other. Furthermore, the fourth flanks 155 of the air guide element 55 of the second air outlet grille 50 are adjacent to the first flanks 140 of the third air outlet grille 100. The respective adjacent flanks 155, 140 are also positioned next to each other in the region of their respective mean lengths. However, the deflection of the outlet air 135 can also be adjusted differently by aligning the respective adjacent flanks 155, 140 not in the region of their respective mean lengths, but possibly with a shorter or longer overlap area.

[0046] As previously described, the air outlet grilles 45, 50, and 100 serve to adjust the direction of the outlet air 135 relative to the xz plane. However, it may also be desirable to adjust the direction of the outlet air 135 relative to the xy plane. For this purpose, an air guide 160 is pivotably mounted about the axis 90 located on the housing 10. According to the embodiment shown here, the air guide 160 consists of two wing-like air guide elements 175, 180, which extend across the width of the housing 10 and are partially shown in sectional view. These elements are spaced apart from each other by a gap 170 and are pivotably mounted about the common axis 90, which extends in the transverse y direction of the air outlet 5.Downstream of the air guide elements 177, 180 are two shell-shaped air guide elements 190, 195, spaced apart from each other by a gap 185 and extending over the width of the housing 10. These shell-shaped air guide elements are shown here partially in cross-sectional view and are in fluidic connection with the air outlet grilles 45, 50 and 100. The air guide elements 175, 180 can be positioned relative to the air guide elements 190, 195 by a suitable pivoting movement such that inlet air 30 passes through the gap 170 over the opening in the housing 10. Fig. The upper shell-shaped air guide element 190 shown in Figure 4 is guided (as in the Fig. 4 shown), or is guided into the gap 185, or is guided under the shell-shaped air guide element 195. In the first case, the inlet air is directed for an outlet from the air outlet 5 in the Fig. 4 downwards, in the second case straight ahead, and in the last case upwards. Thus, the output air 135 is deflected in the Fig. The embodiment shown in 4 is output in a downward and left direction.
