[0008] However, in this air blowing structure, it is generally believed that the driver can still see the lower center register.

[0009] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an air blowing structure having good aesthetics.

[0010] [Technical means to solve the problem]

[0011] (1) The present invention relates to an air blowing structure, comprising a blowing outlet for supplying air to a vehicle interior, wherein in a direction orthogonal to an up-down direction, the direction in which the air is blown out from the blowing outlet is a downstream direction, and the direction opposite to the downstream direction is an upstream direction, the air blowing structure comprising: an upper panel constituting an upper edge portion of an opening of the blowing outlet; a lower panel constituting a lower edge portion of the opening of the blowing outlet; an upper flow path for allowing the air to pass through; and a lower flow path disposed below the upper flow path for allowing the air to pass through; and the upper flow path has an upper opening portion, the upper opening portion opens downward and supplies the air to the vehicle interior through the blowing outlet, the lower flow path has a lower opening portion, the lower opening portion opens upward and supplies the air to the vehicle interior through the blowing outlet, and the opening area of ​​the lower opening portion is smaller than the opening area of ​​the upper opening portion.

[0012] According to the above (1), by reducing the opening area of ​​the lower opening, it is possible to prevent the driver or the like from seeing the opening of the lower opening. Thus, it is possible to provide an air blowing structure 1 with good appearance.

[0013] (2) Optionally, in the air blowing structure described in (1) above, a return portion projecting toward the upstream direction is provided at the lower opening.

[0014] According to the above (2), the opening of the lower opening portion can be made difficult to be seen by the driver or the like. In addition, the upward directivity of the conditioned air blown out from the lower opening portion can be improved.

[0015] (3) Optionally, in the air blowing structure described in (2) above, at least a portion of the upper panel is located closer to the downstream direction than the return portion.

[0016] According to the above (3), it is possible to prevent the driver or the like from seeing the opening of the lower opening portion.

[0017] (4) Optionally, in the air blowing structure described in any one of (1) to (3) above, the lower panel may have an inclined surface that extends obliquely from the opening peripheral edge of the blowing outlet downward and in the downstream direction.

[0018] According to the above (4), the air blown downward from the air outlet is attracted to the inclined surface by the Coanda effect, thereby improving the directivity of the air toward the downward side.

[0019] (5) Optionally, in the air blowing structure described in any one of (1) to (4) above, a curved surface is provided in the upstream direction closer to the upstream direction than the blowing outlet, and the curved surface is arranged between the upper opening portion and the lower opening portion and is convexly curved toward the downstream direction.

[0020] According to (5) above, the air-conditioned air blown upward is attracted to the lower part of the curved surface by the Coanda effect. Thus, the directivity of the air-conditioned air toward the upper part can be improved. In addition, the air-conditioned air blown downward is attracted to the upper part of the curved surface. Thus, the directivity of the air-conditioned air toward the lower part can be improved.

[0021] (6) Optionally, in the air blowing structure described in (5) above, there is a lower fin, which is arranged in the aforementioned lower flow path to change the wind direction of the aforementioned air, and the end of the aforementioned lower fin in the aforementioned downstream direction is located closer to the aforementioned upstream direction than the aforementioned curved surface.

[0022] According to the above (6), it is possible to prevent the driver or the like from seeing the lower fin.

[0023] (7) Optionally, in the air blowing structure described in (5) or (6) above, the curved surface has a decorative portion, and the upper panel has a light-projecting portion that projects light toward the decorative portion.

[0024] According to the above (7), the design of the air blowing structure 1 can be improved. In addition, the attention of the driver and the like can be drawn to the decorative surface, and other parts can be made relatively inconspicuous.

Figure 1 It is a longitudinal sectional view showing the air blowing structure 1 according to the embodiment. Figure 2 This is an external view of the cover portion 4 of the air blowing structure 1 as seen from the vehicle interior 101 side. The air blowing structure 1 is provided in the vehicle 100. The air blowing structure 1 includes a blow-out port 11. The blow-out port 11 supplies conditioned air to the vehicle interior 101 of the vehicle 100.

[0034] In addition, in the following description, the front-to-back direction seen by the driver (i.e., the vehicle length direction of the vehicle 100) is set as the front-to-back direction, the left-to-right direction seen by the driver (i.e., the vehicle width direction of the vehicle 100) is set as the left-to-right direction, and the up-down direction seen by the driver (i.e., the vehicle height direction of the vehicle 100) is set as the up-down direction.

[0035] In the drawings, the front-to-back direction is represented by the X coordinate axis, the rear direction is represented by X1, and the front direction is represented by X2. The left-right direction is represented by the Y coordinate axis, the left direction is represented by Y1, and the right direction is represented by Y2. The up-down direction is represented by the Z coordinate axis, the upper direction is represented by Z1, and the lower direction is represented by Z2.

[0036] like Figure 1 As shown, a vehicle 100 includes a vehicle interior 101 , an air conditioner (not shown) that generates conditioned air, a duct 102 extending from the air conditioner, and an air blowing structure 1 connected to the duct 102 .

[0037] An instrument panel 103 is provided on the front side of the vehicle interior 101. A recessed portion 104 recessed forward is provided on the instrument panel 103. The end of the duct 102 on the vehicle interior 101 side extends to the inner side of the recessed portion 104. Although not shown in the figure, the opening shape of the recessed portion 104 viewed from the vehicle interior 101 side is a rectangle extending in the left-right direction.

[0038] The air blowing structure 1 is provided on the recessed portion 104. The air blowing structure 1 includes a housing 2, a partition 3, a cover 4, a blow-out port 11, left and right fins 7, and upper and lower fins 8. In addition, the conditioned air is blown out toward the rear from the blow-out port 11. Thus, in the present embodiment, the rear direction corresponds to the downstream direction, and the front direction corresponds to the upstream direction.

[0039] The shell 2 is arranged inside the recess 104. The shell 2 is in the shape of a hollow box. Although not shown in the figure, the shell 2 seen from the side of the vehicle compartment 101 is in the shape of a rectangle extending in the left-right direction. An intake port 21 for sucking in conditioned air is provided on the surface on the front side of the shell 2. The intake port 21 is connected to the duct 102. The interior of the duct 102 is connected to the interior of the shell 2. The conditioned air flowing down from the duct 102 flows into the interior of the air blowing structure 1 (shell 2) through the intake port 21. The surface of the shell 2 on its rear side forms an open surface.

[0040] The partition 3 is provided inside the housing 2. The partition 3 divides the internal space of the housing 2 into upper and lower parts. When viewed from the left and right directions, the partition 3 is in a roughly triangular shape that protrudes forward. Although not shown in the figure, the partition 3 extends in the left and right directions. In the internal space of the housing 2, the space above the partition 3 is larger than the space below the partition 3. The partition 3 has a recessed portion 31 that is recessed rearward and upward in the portion on the front and lower side.

[0041] The cover 4 is disposed on the rear side of the housing 2. Figure 2As shown, the cover 4 is in the shape of a strip extending in the left-right direction. The cover 4 is attached to the rear side surface of the housing 2 and the opening peripheral edge of the recess 104 on the vehicle compartment 101 side. The cover 4 has: an upper panel 41 and a lower panel 45 that form a pair of upper and lower panels; an intermediate panel 51 disposed between the upper panel 41 and the lower panel 45; an upper connecting portion 55 that connects the upper panel 41 and the intermediate panel 51; and a lower connecting portion 56 that connects the lower panel 45 and the intermediate panel 51. In addition, the intermediate panel 51 is disposed closer to the front than the upper panel 41 and the lower panel 45.

[0042] The upper panel 41 is arranged along the upper edge of the opening peripheral portion of the recess 104. The upper panel 41 is connected to the upper portion of the surface on the rear side of the housing 2. The upper panel 41 extends in the left-right direction. The upper panel 41 has a first upper inclined portion 42 extending backward and downward from the housing 2 side and a second upper inclined portion 43 rising upward from the end of the rear side of the first upper inclined portion 42 and extending forward. In addition, the connection portion between the first upper inclined portion 42 and the second upper inclined portion 43 constitutes the upper edge of the opening peripheral portion of the air outlet 11.

[0043] The first upper inclined portion 42 constitutes a portion of a peripheral wall portion of an upper flow path 16 described later. The second upper inclined portion 43 is exposed in the vehicle interior 101 .

[0044] A hole 12 penetrating the connection portion in the up-down direction is provided at the connection portion between the upper panel 41 and the housing 2. Although not shown, a plurality of holes 12 are provided in parallel in the left-right direction.

[0045] The lower panel 45 is arranged along the lower edge of the opening peripheral portion of the recess 104. The lower panel 45 is attached to the lower portion of the rear side surface of the housing 2. The lower panel 45 extends in the left-right direction. The lower panel 45 has a first lower inclined portion 46 extending backward and upward from the housing 2 and a second lower inclined portion 47 extending backward and downward from the rear side end of the first lower inclined portion 46. In addition, the connection portion of the first lower inclined portion 46 and the second lower inclined portion 47 constitutes the lower edge of the opening peripheral portion of the air outlet 11.

[0046] The first lower inclined portion 46 constitutes a part of a peripheral wall portion of a lower flow path 18 described later.

[0047] The rear side surface of the second lower inclined portion 47 is exposed to the vehicle interior 101. The rear side surface of the second lower inclined portion 47 forms an inclined surface 47a extending downward and backward from its upper end portion (i.e., the opening peripheral edge portion of the blow-out port 11). In other words, the lower panel 45 has an inclined surface 47a extending downward and backward from the opening peripheral edge portion of the blow-out port 11. In addition, the inclined surface 47a is slightly curved in a convex shape upward and backward.

[0048] A hole 13 penetrating the connection portion in the up-down direction is provided at the connection portion between the lower panel 45 and the housing 2. Although not shown, a plurality of holes 13 are provided in parallel in the left-right direction.

[0049] The middle panel 51 is attached to the rear side of the partition 3. The middle panel 51 extends in the left-right direction. The dimension of the middle panel 51 in the up-down direction is substantially the same as the dimension of the partition 3 in the up-down direction.

[0050] The middle panel 51 has a curved surface 52 on its rear side. The curved surface 52 is curved so that the middle part of the curved surface 52 in the vertical direction is convex to the rear. The curved surface 52 is located closer to the front than the upper panel 41 and the lower panel 45. The curved surface 52 is visible to the driver or the passenger (hereinafter referred to as "driver, etc."). Here, the curved surface 52 has a decorative portion 53.

[0051] The decorative part 53 is, for example, a panel with a pattern, and is provided so as to cover the surface of the curved surface 52 over the entire area. Thus, the appearance design of the air blowing structure 1 can be improved. In addition, the attention of the driver or the like can be drawn to the decorative part 53, making the other parts relatively inconspicuous. In addition, the decorative part 53 is not limited to a panel with a pattern, and can be, for example, a display.

[0052] In addition, the upper panel 41 has a light projection part 421 that projects light onto the curved surface 52 (more specifically, the decorative part 53). The light projection part 421 is provided on the first upper inclined part 42. The light projection part 421 is, for example, an LED. Thus, since the decorative part 53 can be illuminated and enhanced, the appearance design of the air blowing structure 1 can be further improved, and at the same time, the attention of the driver and the like can be more appropriately attracted to the decorative part 53. In addition, the light projection part 421 can emit monochromatic light, can emit light of multiple colors, and can also be a projector that projects an image.

[0053] The connection portion between the upper portion of the middle panel 51 and the upper portion of the partition 3 is provided with a hole portion 14 penetrating the connection portion in the vertical direction. A plurality of holes 14 are arranged in parallel in the horizontal direction. Each hole portion 12 and each hole portion 14 are arranged at an overlapping position when viewed from the vertical direction.

[0054] A hole 15 is provided at the connection portion between the lower portion of the middle panel 51 and the lower portion of the partition 3, penetrating the connection portion in the vertical direction. A plurality of holes 15 are arranged in parallel in the horizontal direction. The holes 13 and the holes 15 are arranged at overlapping positions when viewed from the vertical direction.

[0055] A pair of upper connecting parts 55 are provided. Each upper connecting part 55 connects the left and right ends of the upper panel 41 and the left and right ends of the middle panel 51. The middle part of the upper panel 41 and the middle part of the middle panel 51 are separated. Therefore, the cover 4 has a space surrounded by the upper panel 41, the middle panel 51, and the upper connecting parts 55.

[0056] The space surrounded by the upper panel 41, the middle panel 51, and the upper connecting parts 55 is open to the rear. The opening part having the opening is hereinafter referred to as the "upper opening part 17". The upper opening part 17 is open downward. The space surrounded by the upper panel 41, the middle panel 51, and the upper connecting parts 55 and the space above the partition 3 in the internal space of the shell 2 form a continuous space, and the air-conditioned air flows down in this space. The space formed by the space surrounded by the upper panel 41, the middle panel 51, and the upper connecting parts 55 and the space above the partition 3 in the internal space of the shell 2, including the surrounding wall part surrounding the space, is set as the "upper flow path 16". In other words, the air blowing structure 1 has an upper flow path 16 for air-conditioned air to pass through, and the upper flow path 16 has an upper opening part 17 opening downward. In addition, the surrounding wall part of the upper flow path 16 is configured to include the first upper inclined part 42 and the upper part of the curved surface 52.

[0057] The lower connecting parts 56 are provided as a pair on the left and right. Each lower connecting part 56 connects the left and right ends of the lower panel 45 and the left and right ends of the middle panel 51. The middle part of the lower panel 45 in the left and right direction and the middle part of the middle panel 51 in the left and right direction are separated. Therefore, the cover 4 forms a space surrounded by the lower panel 45, the middle panel 51, and the lower connecting parts 56.

[0058] The space surrounded by the lower panel 45, the middle panel 51, and the lower connecting parts 56 opens to the rear. The opening part having the opening is hereinafter referred to as the "lower opening part 19". The lower opening part 19 opens upward. The space surrounded by the lower panel 45, the middle panel 51, and the lower connecting parts 56 and the space below the partition 3 in the internal space of the shell 2 form a continuous space, and the air-conditioned air flows down in this space. The space formed by the space surrounded by the lower panel 45, the middle panel 51, and the lower connecting parts 56 and the space below the partition 3 in the internal space of the shell 2, including the surrounding wall part surrounding the space, is set as the "lower flow path 18". In other words, the air blowing structure 1 has a lower flow path 18 arranged below the upper flow path 16 for the air-conditioned air to pass through, and the lower flow path 18 has a lower opening part 19 opening upward. In addition, the lower flow path 18 is narrower than the upper flow path 16. Therefore, the flow rate of the conditioned air in the lower flow path 18 is smaller than the flow rate of the conditioned air in the upper flow path 16. In addition, the peripheral wall portion of the lower flow path 18 is configured to include the first lower inclined portion 46 and the lower portion of the curved surface 52.

[0059] The blow-out port 11 is provided on the cover portion 4. The opening shape of the blow-out port 11 is a substantially rectangular shape extending in the left-right direction. The upper edge of the opening periphery of the blow-out port 11 is formed by an upper side panel 41. The lower edge of the opening periphery of the blow-out port 11 is formed by a lower side panel 45. The blow-out port 11 is spatially continuous with both the upper opening portion 17 and the lower opening portion 19. Therefore, the conditioned air blown out from the upper opening portion 17 and the conditioned air blown out from the lower opening portion 19 are supplied into the vehicle interior 101 through the blow-out port 11.

[0060] Here, if the driver or the like can see the lower opening 19 through the air outlet 11 , the appearance of the air outlet structure 1 may be affected.

[0061] Therefore, the opening area of ​​the lower opening 19 is smaller than the opening area of ​​the upper opening 17. By setting the opening area of ​​the lower opening 19 to be smaller, it is possible to prevent the driver or the like from seeing the lower opening 19.

[0062] In addition, the lower opening 19 has a return portion 48 protruding forward from the opening peripheral portion of the lower opening 19. The return portion 48 is provided on the lower panel 45, and more specifically, is provided to protrude forward and upward from the end portion on the rear side of the first lower inclined portion 46. Thus, it is possible to prevent the driver or the like from seeing the lower opening 19.

[0063] In addition, at least a portion of the upper panel 41 is located behind the return portion 48. Specifically, the lower end of the upper panel 41 (i.e., the lower end of the first upper inclined portion 42) is located behind the return portion 48. This prevents the driver or the like from seeing the lower opening 19.

[0064] The left and right fins 7 adjust the direction of the conditioned air. The left and right fins 7 have: a blade portion 71, which is in a rectangular plate shape and the plate surface is arranged in the up-down direction; and a rotation shaft portion 72, which is arranged through the blade portion 71 and rotates around a central axis extending in the up-down direction.

[0065] The left and right fins 7 include upper left and right fins 7A disposed on the upper flow path 16 and lower left and right fins 7B disposed on the lower flow path 18. In addition, the blade portion 71 and the rotation shaft portion 72 of the upper left and right fins 7A are set as blade portions 71A and rotation shaft portions 72A. The blade portion 71 and the rotation shaft portion 72 of the lower left and right fins 7B are set as blade portions 71B and rotation shaft portions 72B. In addition, the lower left and right fins 7B are equivalent to the lower fins. Although not shown in the figure, the upper left and right fins 7A and the lower left and right fins 7B are respectively arranged in parallel in the left-right direction.

[0066] The ends of the rotation shaft 72A of each upper left and right fin 7A in the vertical direction are respectively inserted into each hole 12 and each hole 14. Each upper left and right fin 7A can adjust the direction of the conditioned air blown out from the upper flow path 16 (upper opening 17) in the left and right direction by rotating around its rotation shaft 72A.

[0067] The ends of the rotation shaft 72B of each lower left and right fin 7B in the vertical direction are respectively inserted into each hole 13 and each hole 15. Each lower left and right fin 7B can adjust the direction of the conditioned air blown out from the lower flow path 18 (lower opening 19) to the left and right direction by rotating with its rotation shaft 72B as the center.

[0068] The rear end of each lower left and right fin 7B is located forward of the curved surface 52, specifically, forward of the lower end of the curved surface 52. This can prevent the driver or the like from seeing each lower left and right fin 7B.

[0069] The upper and lower fins 8 adjust the direction of the conditioned air up and down. The upper and lower fins 8 are arranged in front of the partition 3 inside the housing 2. The upper and lower fins 8 have: a blade portion 81, which is in a rectangular plate shape and the plate surface is arranged in the left-right direction; and a rotation shaft portion 82, which is arranged through the blade portion 81 and rotates around the central axis extending in the left-right direction.

[0070] The blade portion 81 is bent at the position of the rotation shaft portion 82, and more specifically, is bent at an obtuse angle so as to protrude upward. The dimension from the end of the rear side of the blade portion 81 to the rotation shaft portion 82 is smaller than the dimension from the end of the front side of the blade portion 81 to the rotation shaft portion 82. The blade portion 81 rotates around the central axis of the rotation shaft portion 82. In addition, the portion of the blade portion 81 that is closer to the front side than the rotation shaft portion 82 is set as the first portion 81a, and the portion that is closer to the rear side than the rotation shaft portion 82 is set as the second portion 81b.

[0071] The upper and lower fins 8 can take four states, namely: the first state (refer to Figure 3 ), the upper flow path 16 and the lower flow path 18 are both open and the plate surface of the first portion 81a is substantially horizontal; the second state (refer to Figure 4 ), the first portion 81a closes the lower flow path 18; the third state (refer to Figure 5 ), the upper flow path 16 is closed by the first portion 81a; and the fourth state (refer to Figure 6 ), the upper flow path 16 is closed by the first portion 81a and the lower flow path 18 is closed by the second portion 81b. The upper and lower fins 8 can be displaced between the first state, the second state, the third state, and the fourth state by rotating around the central axis of the rotating shaft portion 82. In addition, the upper and lower fins 8 can also be set to an intermediate state between the first state and the second state, or an intermediate state between the first state and the third state, or an intermediate state between the third state and the fourth state.

[0072] The rotation shaft 82 is arranged close to the end of the front side of the partition 3. When the upper and lower fins 8 are in the first state, the second state, or a state between them, the second portion 81b is accommodated in the recessed portion 31. In other words, by providing the recessed portion 31 on the partition 3, the interference between the second portion 81b and the partition 3 when the upper and lower fins 8 rotate is avoided. Thus, the movable range of the upper and lower fins 8 (blade portion 81) is ensured. In addition, by bending the blade portion 81 at the position of the rotation shaft 82, the interference between the second portion 81b and the partition 3 when the blade portion 81 is in the second state is suppressed.

[0073] In addition, the opening area of ​​the front side opening of the lower flow path 18 is smaller than the opening of the front side opening of the upper flow path 16. The dimension of the upper and lower fins 8 from the rear side end of the blade portion 81 to the rotation shaft portion 82 is smaller than the dimension from the front side end of the blade portion 81 to the rotation shaft portion 82. Thus, the upper and lower fins 8 can appropriately close both the upper flow path 16 and the lower flow path 18.

[0074] In addition, the left and right fins 7 and the upper and lower fins 8 can be manual or electric. In addition, the upper and lower fins 8 are not necessarily configured. However, when the upper and lower fins are not provided on the air blowing structure, it is preferred that the left and right fins can respectively close the upper flow path 16 and the lower flow path 18.

[0075] Next, regarding the flow of the conditioned air in the air blowing structure 1, refer to Figures 3 to 6 The flow of conditioned air in the air blowing structure 1 differs depending on the state of the upper and lower fins 8. Hereinafter, the case where the upper and lower fins 8 are in the first state, the case where the upper and lower fins 8 are in the second state, the case where the upper and lower fins 8 are in the third state, and the case where the upper and lower fins 8 are in the fourth state will be described. Figure 3 This is a diagram illustrating the flow of conditioned air in the air blowing structure 1 when the upper and lower fins 8 are in the first state. Figure 4 This is a diagram showing the flow of conditioned air in the air blowing structure 1 when the upper and lower fins 8 are in the second state. Figure 5 This is a diagram showing the flow of conditioned air in the air blowing structure 1 when the upper and lower fins 8 are in the third state. Figure 6 8 is a diagram showing the flow of conditioned air in the air blowing structure 1 when the upper and lower fins 8 are in the fourth state. Figures 3 to 5 In the figure, arrows are used to indicate the flow of conditioned air. Figure 6 In the figure, the illustration of conditioned air is omitted.

[0076] like Figure 3 As shown, when the upper and lower fins 8 are in the first state, the conditioned air flows into the upper flow path 16 and the lower flow path 18 respectively. The conditioned air flowing into the upper flow path 16 is blown out from the upper opening 17 toward the bottom and the back. The conditioned air flowing into the lower flow path 18 is blown out from the lower opening 19 toward the top and the back. The conditioned air blown out from the upper opening 17 merges with the conditioned air blown out from the lower opening 19 and blows out from the blow-out port 11. In this case, as viewed in the up-down direction, the direction in which the conditioned air is blown out from the blow-out port 11 is the middle direction between the direction in which the conditioned air is blown out from the blow-out port 11 when the upper and lower fins 8 are in the second state and the direction in which the conditioned air is blown out from the blow-out port 11 when the upper and lower fins 8 are in the third state. Specifically, the conditioned air is in the direction of the body of the driver, etc., in the range from the face to the thigh.

[0077] like Figure 4As shown, when the upper and lower fins 8 are in the second state, the conditioned air flows only into the upper flow path 16. The conditioned air flowing into the upper flow path 16 is blown downward and rearward from the upper opening 17. The conditioned air is blown downward and rearward from the blow-out port 11. In this way, by setting the upper and lower fins 8 to the second state, the direction of the conditioned air blown out from the blow-out port 11 can be adjusted downward. In addition, when the upper and lower fins 8 are in the second state, the direction in which the conditioned air is blown out from the blow-out port 11 is set, for example, so that a part of the conditioned air is separated upward from the driver or the like. In this case, the air volume of the conditioned air that contacts the driver or the like can be reduced.

[0078] In addition, when the air-conditioned air passes near the curved surface 52, it is slightly attracted to the curved surface 52 by the Coanda effect. Thus, the downward directivity of the air-conditioned air is improved. When the air-conditioned air passes near the inclined surface 47a, it is slightly attracted to the inclined surface 47a by the Coanda effect. Thus, the downward directivity of the air-conditioned air is further improved.

[0079] like Figure 5 As shown, when the upper and lower fins 8 are in the third state, the conditioned air flows only into the lower flow path 18. The conditioned air flowing into the lower flow path 18 is blown out upward and rearward from the lower opening 19. The conditioned air is blown out upward and rearward from the blow-out port 11. In this way, by setting the upper and lower fins 8 to the third state, the direction of the conditioned air blown out from the blow-out port 11 can be adjusted upward.

[0080] In addition, when the air-conditioned air passes near the curved surface 52, it is slightly sucked toward the curved surface 52 by the Coanda effect. This improves the upward directivity of the air-conditioned air. By providing the return portion 48 at the lower opening 19, the upward directivity of the air-conditioned air is improved.

[0081] In addition, the lower flow path 18 is narrower than the upper flow path 16. Therefore, the air volume of the conditioned air blown out from the blow-out port 11 is smaller when the upper and lower fins 8 are in the third state than when the upper and lower fins 8 are in the second state. When the upper and lower fins 8 are in the first state, the conditioned air blown out from the blow-out port 11 is the air that merges the conditioned air passing through the upper flow path 16 and the conditioned air passing through the lower flow path 18. Therefore, the air volume of the conditioned air blown out from the blow-out port 11 is the maximum when the upper and lower fins 8 are in the first state.

[0082] like Figure 6 As shown, when the upper and lower fins 8 are in the fourth state, both the upper flow path 16 and the lower flow path 18 are closed by the upper and lower fins 8. In this case, the conditioned air does not flow into the upper flow path 16 or the lower flow path 18. Therefore, by setting the upper and lower fins 8 to the fourth state, the blowing of conditioned air from the air blowing structure 1 can be stopped.

[0083] As described above, the air blowing structure 1 can adjust the wind direction and wind volume of the conditioned air supplied into the vehicle interior 101 by changing the states of the upper and lower fins 8 .

[0084] According to the air blowing structure 1 of this embodiment, the following effects are achieved.

[0085] (1) According to the present embodiment, the opening area of ​​the lower opening 19 is smaller than the opening area of ​​the upper opening 17. By reducing the opening area of ​​the lower opening 19, it is possible to prevent the driver or the like from seeing the opening of the lower opening 19. Thus, it is possible to provide an air blowing structure 1 with good aesthetics.

[0086] Furthermore, by increasing the opening area of ​​the upper opening, the volume of conditioned air supplied from the air outlet 11 into the vehicle interior 101 can be ensured without impairing the aesthetics.

[0087] (2) According to the present embodiment, the return portion 48 protruding forward is provided in the lower opening 19. This makes it difficult for the driver or the like to see the opening of the lower opening 19. In addition, the directivity of the conditioned air blown upward from the lower opening 19 can be improved.

[0088] (3) According to the present embodiment, at least a portion of the upper panel 41 is located rearward of the return portion 48. This can prevent the driver or the like from seeing the opening of the lower opening 19.

[0089] (4) According to the present embodiment, the lower panel 45 has an inclined surface 47a extending obliquely downward and backward from the opening peripheral edge of the air outlet 11. Thus, the air-conditioned air blown downward from the air outlet 11 is sucked toward the second lower inclined portion 47 by the Coanda effect. Thus, the downward directivity of the air-conditioned air can be improved.

[0090] (5) According to the present embodiment, a curved surface 52 is provided on the front side of the air outlet 11, and the curved surface 52 is arranged between the upper opening portion 17 and the lower opening portion 19, and is convexly curved toward the rear. In this case, the air-conditioned air blown upward is attracted to the lower part of the curved surface 52 by the Coanda effect. Thus, the directivity of the air-conditioned air toward the upper part can be improved. In addition, the air-conditioned air blown downward is attracted to the upper part of the curved surface 52. Thus, the directivity of the air-conditioned air toward the lower part can be improved.

[0091] (6) According to the present embodiment, the rear end portions of the lower left and right fins 7B are located forward of the curved surface 52. This can prevent the driver or the like from seeing the lower left and right fins 7B.

[0092] (7) According to the present embodiment, the curved surface 52 has the decorative portion 53. This can improve the design of the air blowing structure 1. In addition, the attention of the driver or the like can be drawn to the decorative portion 53, and other portions can be made relatively inconspicuous.

[0093] In addition, the upper panel 41 (first upper inclined portion 42) has a light projection portion 421 that projects light toward the decorative portion 53. Thus, the decorative portion 53 is illuminated and enhanced, thereby further improving the design of the air blowing structure 1 and attracting the attention of the driver or the like to the decorative portion 53 more appropriately.

[0094] As mentioned above, although the preferred embodiment of the present invention was described, the present invention is not limited to the above-mentioned embodiment, and appropriate changes can be made.

[0095] In the above embodiment, the air blowing structure 1 is provided in the front side of the vehicle interior 101, but may be provided on the left or right side of the vehicle interior 101. In the above embodiment, the downstream direction is the rear direction, but may be the left or right direction.

[0096] In the above embodiment, the air blowing structure 1 supplies the conditioned air generated by the air conditioning device into the vehicle interior 101, but the present invention is not limited thereto. The air blowing structure may also supply the outside air or the inside air of the vehicle directly into the vehicle interior, for example. That is, the air supplied into the vehicle interior by the air blowing structure is not limited to the conditioned air.
