Description

Technical Field

[0001] The invention relates to an air outflow element having the features of the preamble of claim 1 . Background Art

[0002] The air outflow piece is used to supply hot or cold air into the passenger compartment of the motor vehicle and to divert the air flow into the passenger compartment. The air outflow piece is typically installed in a recessed manner in the dashboard or another interior lining in the passenger compartment of the motor vehicle.

[0003] Publication DE 10258747 A1 discloses an air outlet having a so-called heat-conducting nozzle, which is designed to be installed in the so-called roof of a motor vehicle. A roof, also known as a roof, is an interior lining of the passenger compartment of a motor vehicle, located below the vehicle roof. The heat-conducting nozzle of the known air outlet is cylindrical and tubular and can be pivoted about its central longitudinal axis. The heat-conducting nozzle has a curved air deflection channel with a constant longitudinal cross-section over the axial length of the heat-conducting nozzle, which extends through the central longitudinal axis of the heat-conducting nozzle and bends at the central longitudinal axis. Due to the bend, the air deflection channel of the heat-conducting nozzle of the known air outlet redirects the air flow flowing in between the vehicle roof and the roof downwardly into the passenger compartment of the vehicle. By pivoting the heat-conducting nozzle, air can be diverted from the outflow direction of the heat-conducting nozzle, or from the air outlet, into the passenger compartment of the vehicle. Summary of the Invention

[0004] The object of the present invention is to provide an air outflow element with a pivotable air deflection nozzle, which has a modified air guidance, the air outflow element being suitable for installation in the A-pillar, B-pillar or C-pillar of a motor vehicle, in the vehicle roof, door lining or the like, the air outflow element then being able to be installed in a flat installation space and having an outflow at an angle relative to the inflow.

[0005] This object is achieved according to the invention by the features of claim 1 .

[0006] According to the present invention, an air outlet element comprises an air inlet channel and an air deflection nozzle that is pivotable about a pivot axis arranged transversely to the air inlet channel. For example, the pivot axis of the air deflection nozzle extends transversely to the longitudinal centerline of the air inlet channel through the geometric center of gravity of the cross section of the air inlet channel. The channel wall of the air deflection nozzle can be partially formed by the channel wall of the air inlet channel of the air outlet element.

[0007] The air deflection channel of the air deflection nozzle has an air inlet opening at a first circumferential position of the air deflection nozzle and an air outlet opening at a second circumferential position of the air deflection nozzle. The air outlet opening is offset relative to the air inlet opening in the circumferential direction of the air deflection nozzle so as to deflect the air flow through the air deflection channel of the air deflection nozzle, i.e., the air flows out of the air deflection nozzle at an angle relative to the air inflow. In the open position, the air inlet channel of the air outlet element according to the invention communicates with the air inlet opening of the air deflection channel of the air deflection nozzle so that air flowing through the air inlet channel in the direction of the air deflection nozzle flows into the air deflection channel of the air deflection nozzle and flows out again through the air outlet opening.

[0008] Each pivot position of the air deflection nozzle, in which the air inlet channel is in communication with the air inlet opening of the air deflection channel of the air deflection nozzle, is referred to herein as an "open position." The air deflection nozzle can have a closed position, that is, one (or more) pivot positions in which the air deflection nozzle blocks the air inlet channel or in which the air inlet opening of the air deflection channel of the air deflection nozzle is not in communication with the air inlet channel. However, the closed position of the air deflection nozzle is not mandatory for the present invention.

[0009] By pivoting the air deflection nozzle about its pivot axis, the air outflow opening of the air deflection channel of the air deflection nozzle can be adjusted along the circumferential direction of the air deflection nozzle relative to the air inlet channel, and thus the direction of the air outflow from the air outflow piece can be adjusted, that is, the following angle can be changed, at which the air flows out from the air outflow piece relative to the air inlet channel.

[0010] The present invention provides that the air deflection channel of the air deflection nozzle is guided around the pivot axis at a radial distance from the pivot axis of the air deflection nozzle in such a manner that the entire air flow flowing through the air outlet element is guided around the pivot axis by the air deflection channel. The air deflection channel is located completely outside the pivot axis, and the pivot axis is preferably located outside the air deflection channel at a radial distance from the pivot axis. The air deflection channel is guided past or around the pivot axis on one side of the pivot axis of the air deflection nozzle and not on both sides.

[0011] The invention makes it possible to achieve a larger radius of air deflection about the pivot axis in the air deflection channel of the air deflection nozzle.

[0012] The dependent claims have as their subject matter advantageous embodiments and developments of the invention specified in claim 1 .

[0013] In the central open position of the air deflection nozzle, the air outflow element according to the invention has an angle between the air outflow and the longitudinal direction of the air inlet channel of, for example, approximately 90°, or an angle between, on the one hand, approximately 30°, approximately 45°, or approximately 60° and, on the other hand, approximately 120°, approximately 135°, or approximately 150°, wherein the angle can be adjusted in two directions, for example, by pivoting the air deflection nozzle about the pivot axis, to approximately 30°, approximately 45°, or approximately 60°. From the central open position, the air deflection nozzle can be pivoted to the same extent in both directions, or the air outflow can be adjusted to the same extent in both directions.

[0014] To achieve the closed position, the design of the present invention provides for the air deflection nozzle to be designed in the manner of a rotary slide valve. In one embodiment, the air deflection nozzle of the air outlet element has a partially cylindrical blocking wall coaxial with the pivot axis of the air deflection nozzle, extending over a peripheral section of the air deflection nozzle. In the closed position, the blocking wall blocks the air inlet channel, whereas in one or more open positions, the air inlet channel communicates with the air inlet opening of the air deflection channel of the air deflection nozzle. Depending on the pivot position of the air deflection nozzle, the blocking wall can partially block the flow cross section of the air inlet channel.

[0015] The embodiment of the invention provides that the air deflection nozzle has an inner channel wall which internally delimits the air deflection channel at a radial distance from the pivot axis of the air deflection nozzle. An outer channel wall externally delimits the air deflection channel at a greater radial distance from the pivot axis. The outer channel wall can be part of the air deflection nozzle or, for example, also a channel wall of the air inlet channel. The pivot axis is located outside the air deflection channel, i.e., on the side of the inner channel wall facing away from the outer channel wall.

[0016] The design of the present invention provides an inner channel wall having a fan-like shape when viewed in the direction of the pivot axis: the inner channel wall comprises a central wall section and two wall sections. In this design of the present invention, the central wall section of the inner channel wall of the air deflection channel of the air deflection nozzle is guided around the pivot axis of the air deflection nozzle, preferably in an arcuate manner, on the outside. The central wall section can also be guided around the pivot axis of the air deflection nozzle in a single or multiple curved manner. The pivot axis of the air deflection nozzle is located on the concave side of the central wall section of the channel wall of the air deflection channel. Two wall sections—straight or not straight and tangentially or not tangentially—lead outward from the central wall section of the inner channel wall to two peripheral locations of the air deflection nozzle spaced apart from one another along the peripheral direction of the air deflection nozzle.

[0017] The embodiment of the invention provides a nozzle-fixed first partition wall, ie, pivotable together with the air deflection nozzle, which blocks the air deflection nozzle from throughflow between the pivot axis and a peripheral position of the air deflection nozzle.

[0018] Another embodiment of the present invention provides a second partition wall that is fixed relative to the air inlet channel, extends radially into the air deflection nozzle, and blocks the air deflection nozzle from flow between the pivot axis and the peripheral position of the air deflection nozzle fixed relative to the air inlet channel. The second partition wall ensures that air flows around the pivot axis of the air deflection nozzle only on the side opposite the partition wall. The air outflow element can optionally include one of the two partition walls or both partition walls, with the first partition wall not necessarily requiring the second partition wall, and vice versa.

[0019] The design of the present invention provides a raised portion of the air inlet channel that extends within a peripheral section of the air deflection nozzle and curves radially outward away from the pivot axis of the air deflection nozzle, or from the peripheral edge of the air deflection nozzle. Air from the air inlet channel can flow through the raised portion to the air inlet opening of the air deflection channel of the air deflection nozzle. The raised portion can increase the flow cross section of the air inlet channel or guide air from the air inlet channel around the periphery of the air deflection nozzle to the air inlet opening of the air deflection channel of the air deflection nozzle.

[0020] For example, one or more adjustable air-deflecting elements are preferably arranged in the air-deflecting channel of the air-deflecting nozzle, by means of which the air flow flowing through the air-deflecting channel can be deflected obliquely relative to a radial plane of the pivot axis. This allows for two-dimensional air deflection. For example, one or more plates can be arranged in the air-deflecting channel, which plates can be pivoted about an axis that is radial to the pivot axis of the air-deflecting nozzle or parallel to the radial direction of the pivot axis.

[0021] The one or more air deflecting elements are preferably adapted to the shape of the air deflecting channel, ie their contour at least approximately corresponds to the cross section of the air deflecting channel in a radial plane relative to the pivot axis of the air deflecting nozzle. For example, the one or more air deflecting elements are arcuate.

[0032] The accompanying drawings are simplified diagrams for explaining and understanding the present invention. In principle, identical components are provided with identical reference numerals in the figures.

[0033] exist Figures 1 to 4 The air outlet element 1 according to the invention shown in FIG. 1 has an air inlet channel 2 and an air deflection nozzle 3 that can be pivoted about a pivot axis 4 extending transversely to the air inlet channel 2. The air inlet channel 2 can have essentially any cross-section and does not have to extend straight. In the exemplary embodiment, the air inlet channel 2 has a rectangular cross-section and extends to the air deflection nozzle 3 with two small bends. In the exemplary embodiment, the pivot axis 4 of the air deflection nozzle 3 extends parallel to the long sides of the air inlet channel 2.

[0034] The air deflection nozzle 3 comprises a cylindrical core 5, a cylindrical shell-shaped outer wall radially spaced from the core 5, two sector-shaped end walls 6 at the axial ends of the air deflection nozzle 3, and a first partition wall 7, which extends tangentially to the core 5 to the outer periphery of the end walls 6, wherein the outer periphery of the end walls 6 can also be understood as the outer periphery of the air deflection nozzle 3. The two end walls 6 and the first partition wall 7 connect the core 5 and the cylindrical shell-shaped outer wall of the air deflection nozzle 3 to one another. The core 5, the end walls 6, and the cylindrical shell-shaped outer wall of the air deflection nozzle 3 are coaxial with respect to one another and with respect to the pivot axis 4 of the air deflection nozzle 3.

[0035] The circumference of the core 5 can be understood as the inner channel wall 8, and the outer wall as the outer channel wall 9 of the air deflection channel 10 of the air deflection nozzle 3 of the air outflow element 1 according to the invention, which is laterally delimited by the end wall 6. The outer channel wall 9 has a greater radial distance from the pivot axis 4 of the air deflection nozzle 3 than the inner channel wall 8. The air deflection channel 10 is guided around the pivot axis 4 in an arc-shaped manner on one side, with the inner and outer channel walls 8, 9 being located on the same side of the pivot axis 4, and the pivot axis 4 being located outside the air deflection channel 10.

[0036] The outer channel wall 9 ends at a distance from the outer, in the exemplary embodiment axially parallel edge of the first partition wall 7 in the circumferential direction of the air deflection nozzle 3 so that an air outflow opening 11 of the air deflection nozzle 3 and of the air deflection channel 10 of the air deflection nozzle 3 is located between the outer channel wall 9 and the first partition wall 7 .

[0037] The air outlet element 1 has a cylindrical, tubular nozzle housing 12, into which the air inlet channel 2 opens tangentially and which can also be understood as part of the air inlet channel 2. The nozzle housing 12 has a cylindrical, shell-shaped outer wall 13, two circular end walls 14 at the end sides of the nozzle housing 12, and a second partition wall 15 that projects radially inward from the outer periphery of the nozzle housing 12, or the end walls 14, to the core 5 of the air deflection nozzle 3, the periphery of which forms the inner channel wall 8 of the air deflection channel 10. The outer wall 13 and the end walls 14 of the nozzle housing 12 are coaxial with the pivot axis 4 of the air deflection nozzle 3. The outer channel wall 9 of the air deflection nozzle 3 rests internally against the outer wall 13 of the nozzle housing 12, or a narrow gap is formed between the outer wall 13 of the nozzle housing 12 and the outer channel wall 9 of the air deflection nozzle 3.

[0038] The first partition wall 7 is fixed to the air deflection nozzle 3 of the air outflow element 1 according to the invention, that is, the first partition wall 7 pivots together with the air deflection nozzle 3, whereas the second partition wall 15 does not pivot together but is fixed relative to the air inlet channel 2. The two partition walls 7, 15 block the air deflection nozzle 3 from flowing through on the side of the core 5 and of the pivot axis 4 opposite the air deflection channel 10.

[0039] On the side of the outer duct wall 9 of the air deflection nozzle 3 facing away from the air outflow opening 11, there is an opening between the outer duct wall 9 and the core 5 of the air deflection nozzle 3 or the inner duct wall 8 formed by the outer circumference of the core 5. This opening forms an air inlet opening 16 of the air deflection duct 10 of the air deflection nozzle 3, which is offset relative to the air outflow opening 11 in the circumferential direction of the air deflection nozzle 3.

[0040] In addition to the air deflection nozzle 3 Figure 4 In addition to the closed position shown in the figure, the air inlet opening 16 of the air deflection channel 10 of the air deflection nozzle 3 of the air outflow piece 1 according to the present invention is directly or indirectly connected to the air inlet channel 2 via the nozzle housing 12 so that the air flowing through the air inlet channel 2 in the direction of the air deflection nozzle 3 flows into the air deflection channel 10 of the air deflection nozzle 3 and flows through the air deflection channel 10 of the air deflection nozzle 3 and flows out through the air outflow opening 11 of the air deflection channel 10.

[0041] The air deflection nozzle 3 of the air outflow element 1 according to the invention can also be pivoted to Figure 4The closed position is shown. In the closed position, the outer channel wall 9 blocks the air inlet channel 3 in the manner of a rotary slide valve. In the closed position of the air deflection nozzle 3, the outer channel wall 9 of the air deflection nozzle 3, which can also be understood as a blocking wall 20 of the air deflection nozzle 3 or, more generally, of the air outlet element 1, blocks the air inlet channel 3. At the same time, the outer wall 13 of the nozzle housing 12 blocks the air outlet opening 11 of the air deflection channel 10. All other pivot positions of the air deflection nozzle 3, other than the closed position, in which the air deflection channel 10 of the air deflection nozzle 3 is connected to the air inlet channel 2, are referred to as open positions.

[0042] By pivoting the air deflection nozzle 3 about the pivot axis 4, as in Figure 2 and Figure 3 As can be seen in the figure, the air outflow opening 11 can be adjusted along the circumferential direction of the air deflection nozzle 3, thereby also adjusting the direction of the air outflow 17 from the air outflow element 1 according to the invention. In the exemplary embodiment, the air outflow 17 can be adjusted at an angle of approximately 90°, wherein in the exemplary embodiment, the central air outflow 17 is at an angle of approximately 90° relative to the longitudinal direction of the air inflow channel 2. This angle can be determined differently in the embodiments of the invention.

[0043] To deflect the air outflow 11 from the air outflow element 1 in the second dimension, pivotable blades 18, generally also referred to as air deflection elements, are arranged parallel to one another in the air deflection channel 10 of the air deflection nozzle 3. In the exemplary embodiment, the blades 18 have an arcuate shape adapted to the shape of the air deflection channel 10. The blades 18 are pivotable about pivot axes 24 that are parallel to one another and radial to the pivot axis 4 of the air deflection nozzle 3. The blades 18 pivot together parallel to one another.

[0044] The air outlet element 1 according to the present invention is designed to be installed in an A-pillar, B-pillar, or C-pillar of a motor vehicle (not shown). An air inlet channel 2 is arranged longitudinally in the A-pillar, B-pillar, or C-pillar, and an air deflection nozzle 3, including a nozzle housing 12, is arranged in the A-pillar, B-pillar, or C-pillar. Air flowing through the air inlet channel 2 into the air deflection channel 10 of the air deflection nozzle 3 is deflected in the air deflection nozzle 3 and then flows into the passenger compartment of the motor vehicle. The direction of the air outflow 17 into the passenger compartment can be deflected two-dimensionally by pivoting the air deflection nozzle 3 about the pivot axis 4 and by pivoting the plate 18 forming the air deflection element. The figures show a detail of an interior lining 19 of the interior lining of the passenger compartment of a motor vehicle (not shown), which covers the A-pillar, B-pillar, or C-pillar of the motor vehicle. The interior lining 19 has an opening 25 through which air flows out of the air outlet element 1.

[0045] Instead of being arranged in the A-, B-, or C-pillars, the air outflow element 1 according to the present invention can also be arranged, for example, on the vehicle roof, the door lining, or another interior lining of the passenger compartment of the motor vehicle (not shown). The vehicle roof, also referred to as the roof, is the interior lining of the body of the motor vehicle below the vehicle roof. In principle, the air outflow element 1 according to the present invention can be arranged in confined installation spaces that require an outflow at an angle relative to the inflow.

[0046] The air outlet element 1 according to the present invention is Figures 5 to 8 In the second embodiment shown in Figures 1 to 4 In comparison, the nozzle housing 12 and the air deflection nozzle 3 are modified, wherein the structure and function of the two exemplary embodiments are identical.

[0047] Figures 5 to 8 The nozzle housing 12 of the air outlet element 1 has a projection 21 at which the outer wall 13 is curved outward. The projection 21 is curved radially outward, away from the pivot axis 4 of the air deflection nozzle 3. The projection 21 extends circumferentially from the air inlet channel 2 to such a distance that air can flow from the air inlet channel 2 directly into the air deflection channel 10 of the air deflection nozzle 3, as well as through the projection 21. The projection 21 is open radially inward so that the air flow is not divided. The projection 21 increases the flow cross section and the radius of the air flow during its deflection.

[0048] As in Figures 1 to 4 Like in Figures 5 to 8 The air deflection nozzle 3 of the air outflow element 1 according to the invention shown in FIG has a cylindrical core 5, a cylindrical shell-shaped outer wall radially spaced from the core 5, and two end walls 6 at the axial ends of the air deflection nozzle 3. The end walls 6 are Figures 5 to 8 The air deflection nozzle 3 is circular in shape, and the core 5, end wall 6, and cylindrical outer wall are coaxial relative to one another and to the pivot axis 4 of the air deflection nozzle 3. The cylindrical outer wall forms the outer channel wall 9, and a section of the cylindrical core 5 forms the central wall section 22 of the inner channel wall 8. Two wall sections 23 extend tangentially outward from the central wall section 22 of the inner channel wall 8 to the outer periphery of the air deflection nozzle 3 relative to the core 5. These two wall sections can also be understood as dividing walls of the air deflection nozzle 3. The two wall sections 23 of the inner channel wall 8 of the air deflection channel 10 of the air deflection nozzle 3 extend at an angle relative to one another so that they form a fan shape. At the outer periphery of the air deflection nozzle 3, the wall sections 23 are connected by a cylindrical wall coaxial with the pivot axis 4 of the air deflection nozzle 3, which can be understood as a blocking wall 20. The blocking wall 20 is approximately opposite the outer channel wall 9.

[0049] Figure 5 and 6 The air deflection nozzle 3 is shown in the same pivot position, which is a central pivot position of the air deflection nozzle 3 from which the air deflection nozzle 3 can be pivoted approximately to the same extent in both directions. Figure 7 and Figure 8 The pivot position of the air deflection nozzle 3 , from which the air outflow 17 can be adjusted approximately to the same extent in both directions by pivoting the air deflection nozzle 3 , can also be understood as a central pivot position.

[0050] like Figures 1 to 4 As in the example, the air deflection channel 10 is also provided with a Figures 5 to 8 A pivoted plate 18 in the air deflection nozzle 3 of the air outflow piece 1 serves as an air deflection element for deflecting the air outflow 17 from the air outflow piece 1 in the second dimension.
