Description

Technical Field

[0001] The present invention relates to an air blowing device of an air conditioner mounted on a vehicle. Background Art

[0002] Generally, outlets (also referred to as "air conditioning vents" or "exhaust outlets") for blowing out air conditioned by an air conditioner are arranged on both sides of the dashboard of a car in the vehicle width direction (for example, see Patent Document 1).

[0003] The vehicle air-regulating device 1 described in Patent Document 1 has a large rectangular main opening 31 in the center of a cover 30 provided at the end of the vehicle compartment, and vertically elongated auxiliary openings 32 are provided on the left and right of the main opening 31. The air-conditioned air blown out from the main opening 31 can be changed in the vertical, horizontal, and left-right directions by operating the operating knob 45 of the air-direction adjusting mechanism 40.

[0004] In addition, by operating the operation dial 52 of the flow path selection mechanism 50, the air conditioning wind blown out from the blow-out port 15y is blown out from the inner flow path 15a and the peripheral flow path 15b, or blown out only from the inner flow path 15a. In addition, in the vehicle air modulator device 1, the air is blown to a wide range by providing the longitudinal auxiliary openings 32 on the left and right sides of the main opening 31. A partition is provided near the opening of the auxiliary opening 32 to prevent foreign matter from entering.

[0008] Problems to be solved by the invention

[0009] However, the auxiliary opening 32 of the vehicle air damper device 1 described in Patent Document 1 has a problem of poor appearance design because the partition for preventing foreign matter from entering is located near the opening of the auxiliary opening 32 and can be seen from the vehicle cabin side.

[0010] Furthermore, when a substantially linear outlet such as the auxiliary opening 32 is formed to be wide in the left-right direction in order to blow air over a wider range, there is a problem that the wind direction deflects compared to a substantially linear outlet.

[0011] Therefore, an object of the present invention is to provide an air blowing device having a good appearance that can suppress entry of foreign matter into a duct and prevent deflection of conditioned air blown out from a blower outlet.

[0052] <<Vehicles>>

[0053] exist Figure 1 The vehicle A shown is equipped with an air conditioner (not shown) for adjusting the temperature and humidity of the air in the vehicle. An instrument panel 1 is provided at the front of the vehicle A, and air blowing devices 2 are arranged at the center and both ends of the instrument panel 1 in the vehicle width direction.

[0054] <<Air Conditioning Unit>>

[0055] The air conditioner (not shown) is connected to the air outlet 60, 70 (see Figure 2 and Figure 3 The air whose temperature and humidity are regulated by an air conditioning device (not shown) is blown out from the air outlet 30 of the air blowing device 2 into the vehicle interior.

[0056] <<Air Blowing Device>>

[0057] The air blowing device 2 includes an air blowing device 2A provided on the right side in the vehicle width direction (driver's seat side) in the instrument panel 1, an air blowing device 2B provided on the left side in the vehicle width direction (passenger seat side), and an air blowing device 2C provided on the center side in the vehicle width direction. The air blowing device 2A and the air blowing device 2B are formed into a left-right symmetrical shape. The air blowing device 2C is formed into a single rectangular opening in general. In the following, the air blowing device 2A on the right side in the vehicle width direction among the air blowing devices 2 is mainly described, and the description of the air blowing devices 2B and 2C is appropriately omitted.

[0058] like Figure 2 or Figure 3 As shown, the air blowing device 2, 2A is composed of a front housing 3, an operating mechanism 4, a louver unit 5, an inner housing 6, an outer housing 7 and a flow path selection mechanism 8. Figure 3As shown, the air blowing device 2 includes an inlet 60 , 70 for allowing air to flow into the air blowing device 2 , 2A, an outlet 30 for blowing air into the vehicle interior, and a ventilation passage 71 disposed between the outlet 30 and the inlet 60 , 70 .

[0059] <<Front Housing>>

[0060] The front housing 3 is a housing mounted on the vehicle interior side of the instrument panel 1. The front housing 3 is provided with a blow-out port 30, which is composed of an inner blow-out port 31 provided on the inner side of the front housing 3 in the vehicle width direction and an outer blow-out port 32 provided on the outer side of the front housing 3 in the vehicle width direction. In addition, an operating mechanism 4 and an operating mechanism installation housing 40 are arranged between the inner blow-out port 31 and the outer blow-out port 32 of the front housing 3.

[0061] <Blowing outlet>

[0062] The outlet 30 is an outlet for blowing conditioned air such as warm air or cold air sent from an air conditioner (not shown) into the vehicle interior. The outlet 30 of the air blowing device 2 is provided with an inner outlet 31 and an outer outlet 32.

[0063] <Inside air outlet>

[0064] The inner blow-out port 31 is one of the blow-out ports 30 disposed on the inner side in the vehicle width direction. The inner blow-out port 31 is formed as a structure in which a louver is installed in a single rectangular opening. That is, the inner blow-out port 31 is provided with a louver unit 5 on the inner side thereof, and the air conditioning wind blown out from the inner blow-out port 31 can be adjusted in the up, down, left, and right directions by the louver unit 5.

[0065] <Outside air outlet>

[0066] like Figure 4 As shown, the outer blow-out port 32 is arranged outside the inner blow-out port 31 in the vehicle width direction. The outer blow-out port 32 (blow-out port 30) has an upper blow-out region 32a extending in the vehicle width direction and a side blow-out region 32b extending continuously downward from an outer end portion 32g in the vehicle width direction of the upper blow-out region 32a.

[0067] like Figure 4 As shown, the upper blowing area 32a has an upper side 32c and a lower side 32d and is formed to be elongated in the vehicle width direction. The upper blowing area 32a is provided on the upper surface of the instrument panel 1. The upper blowing area 32a is arranged to overlap with the operating mechanism 4 in the vertical direction.

[0068] like Figure 6As shown, the upper side 32c of the outer blow-out port 32 is arranged in front of the vehicle compared with the lower side 32d. Therefore, the lower side 32d is formed at a position separated from the upper side 32c to the rear (the vehicle compartment side) by a distance L2. The outer blow-out port 32 between the upper side 32c and the lower side 32d is formed in an oblique upward direction (arrow a direction) from the ventilation path 71 in the outer shell 7 to the rear (the vehicle compartment side). The outer blow-out port 32 is inclined upward at θ1 relative to the horizontal direction when observed in a longitudinal section.

[0069] like Figure 4 As shown, the side blowing area 32b has an inner side 32e and an outer side 32f, and is formed elongated in the vertical direction. The side blowing area 32b is arranged so as to overlap with the inner blowing outlet 31 in the vehicle width direction. In addition, the side blowing area 32b is arranged so as to overlap with the operating mechanism 4 in the vehicle width direction.

[0070] Here, “overlapping in the vehicle width direction” means that the side blowing area 32 b overlaps with the projection areas of the inner blowing port 31 and the operating mechanism 4 projected in the vehicle width direction when viewed from the side.

[0071] like Figure 7 As shown, the outer edge 32f of the outer blow-out port 32 protrudes toward the rear of the vehicle compared to the inner edge 32e. Therefore, the outer edge 32f is formed at a position separated from the inner edge 32e by a distance L3 toward the rear (toward the vehicle interior). The outer blow-out port 32 between the outer edge 32f and the inner edge 32e is formed toward the rear (toward the vehicle interior) from the ventilation path 71 in the outer shell 7 and toward the inside in the vehicle width direction (the direction of arrow b).

[0072] <<Operating Mechanism>>

[0073] like Figure 4 As shown in FIG. 1 , the operating mechanism 4 is a switching operating member for discharging or blocking the conditioned air sent from the air conditioner (not shown) from the inner blow-out port 31 or the outer blow-out port 32. The operating mechanism 4 includes, for example, a rotating operating portion 41, which is rotatably provided on a panel portion 40a of the operating mechanism housing 40. The operating mechanism 4 rotates the operating portion 41, thereby controlling the flow path selection mechanism 8 (see FIG. 1 ). Figure 3 ) by rotating the stop valves 81 and 82, the operation can be switched to the closed mode 4a, the inside blowing mode 4b, or the outside blowing mode 4c. The operating mechanism 4 is arranged to be offset to the outside in the vehicle width direction by a distance L1 compared to the middle position 3a between the vehicle width direction outside end 31a of the inside blowing outlet 31 and the vehicle width direction inside end 32h of the side blowing area 32b of the outside blowing outlet 32.

[0074] The operating part 41 is composed of a substantially cylindrical knob. A scale-shaped indicator 41a is provided on the surface of the operating part 41 on the vehicle compartment side to serve as a mark for the rotation operation. Figure 7 As shown in FIG. 1 , the operating portion 41 is arranged to be inclined inward in the vehicle width direction. That is, the operating portion 41 is inclined inward in the vehicle width direction at an angle θ2 relative to the front housing 3 when viewed from above. Therefore, the operating portion 41 is arranged to be inclined toward the passenger sitting in the front seat. Figure 6 As shown, the operation portion 41 is arranged to be inclined downward at an angle θ3 with respect to the horizontal direction when viewed from the side.

[0075] On the panel portion 40a of the operating mechanism setting housing 40, marks indicating three positions of the closed mode 4a, the inside blowing mode 4b and the outside blowing mode 4c are marked around the operating portion 41. The panel portion 40a of the operating mechanism setting housing 40 is arranged between the inside blowing port 31 and the side blowing area 32b of the outside blowing port 32 in the front housing 3.

[0076] The closed mode 4a is a mode in which air is not blown out from either the inner blow-out port 31 or the outer blow-out port 32. The closed mode 4a is arranged at the lower side of the operation unit 41. That is, the closed mode 4a is arranged to be switched by moving the operation unit 41 to a downward position where the inner blow-out port 31 and the outer blow-out port 32 are not provided.

[0077] The inside blowing mode 4b is a mode in which air is blown out from the inside blowing port 31. The inside blowing mode 4b is provided on the inside in the vehicle width direction of the operation portion 41 (leftward of the position where the inside blowing port 31 is provided).

[0078] The outside blowing mode 4c is a mode in which air is blown out from the outside blowing port 32. The outside blowing mode 4c is provided on the upper side of the operation portion 41 (in an upward position where the upper blowing region 32a of the outside blowing port 32 is provided).

[0079] <<Louvre Unit>>

[0080] like Figure 3 As shown, the louver unit 5 is a device for adjusting the direction of the air conditioning wind blown out from the inner blow-out port 31 to the up, down, left, and right directions. The louver unit 5 is composed of a horizontal louver body 51, a vertical louver body 52, a connecting rod member 53, and a louver operating handle 54. The louver unit 5 is arranged on the front side of the inner blow-out port 31 of the front housing 3.

[0081] The horizontal louver body 51 is a component for adjusting the direction of the air conditioning wind blown out from the inner air outlet 31 to the vertical direction. The horizontal louver body 51 is composed of three flat horizontal louvers 51a extending in the vehicle width direction, connecting longitudinal plate portions 51b provided at the left and right ends of the three horizontal louvers 51a, and a pitching movement shaft portion 51c protruding from the upper and lower central portions of the left and right connecting longitudinal plate portions 51b.

[0082] The vertical louver body 52 is a member for adjusting the direction of the conditioned air blown out from the inner blowout port 31 to the left and right. The vertical louver body 52 includes a plurality of vertical louvers 52a extending in the up-down direction and a rotation shaft 52b protruding from the upper portion of the vertical louvers 52a.

[0083] The link member 53 is a connecting member that connects a plurality of longitudinal louver bodies 52 arranged at appropriate intervals in the vehicle width direction so that they rotate integrally around the rotation shafts 52b. The link member 53 is composed of a plate-shaped member that extends in the vehicle width direction and into which the rotation shafts 52b are fitted.

[0084] The louver operating handle 54 is an operating member that is operated in the up-down direction to make the horizontal louver body 51 pitch and move in the up-down direction around the pitch moving shaft 51c, and is operated in the left-right direction to make the vertical louver body 52 rotate in the left-right direction around the rotation shaft 52b. The louver operating handle 54 is composed of a thick plate-shaped member that is arranged on the horizontal louver 51a in the center so as to slide freely in the horizontal direction. An arm (not shown) is provided at the front end of the louver operating handle 54, and the arm engages with the vertical louver 52a to rotate the vertical louver body 52 in the left-right direction around the rotation shaft 52b.

[0085] <<Inner Shell>>

[0086] like Figure 3 As shown, the inner housing 6 is a square cylindrical housing for forming a ventilation path 61, wherein the ventilation path 61 conveys the air entering the inner housing 6 from the inlet 60 through the passage of the air conditioning device (not shown) to the inner blow-out port 31. The stop valve 81 of the flow path selection mechanism 8 for opening and closing the ventilation path 61 is rotatably supported in the inlet 60 of the inner housing 6.

[0087] <<Outer shell>>

[0088] like Figure 3 and Figure 8 As shown, the outer shell 7 is a cylindrical shell for forming a ventilation path 71, and the ventilation path 71 transports the air entering the outer shell 7 from the inlet 70 through the passage of the air conditioner (omitted in the figure) to the outer blow-out port 32. Figure 3 or Figures 11 to 13 As shown, the outer shell 7 is formed by matching the inner shell half 7a arranged on the inner side in the vehicle width direction with the outer shell half 7b arranged on the outer side in the vehicle width direction. The stop valve 82 of the flow path selection mechanism 8 for opening and closing the ventilation path 71 is rotatably supported in the inlet 70 of the outer shell 7.

[0089] The ventilation passage 71 is formed with a deformed portion 72 and a rectifying fin 73 .

[0090] like Figure 3 , Fig.11 and Fig.12 As shown, the deformed portion 72 is observed in a longitudinal section, and as it approaches the blow-out port 30, it extends from the quadrilateral inlet 70 (see Fig.13 ) gradually changes into an inverted L-shaped outlet 30 (refer to Fig.11 and Fig.12 The deforming portion 72 includes an upper deforming portion 72a extending in the vehicle width direction and a side deforming portion 72b extending continuously downward from an outer end portion 72c in the vehicle width direction of the upper deforming portion 72a.

[0091] A plurality of plate-shaped rectifying fins 73 are provided on the upper deformed portion 72a and the side deformed portion 72b, respectively. A wall portion 72d is provided at the inner end portion of the upper deformed portion 72a in the vehicle width direction. Fig. 9 As shown, the portion of the wall portion 72d near the rear opening end is inclined at an inclination angle θ4 (for example, 60 degrees) substantially the same as the inclination angle θ5 (for example, 60 degrees) of the upper rectifying fin 73a with respect to the front-rear direction (ventilation direction) when viewed in cross section. Therefore, the wall portion 72d is formed to be inclined so as to gradually expand in the rearward direction (vehicle compartment direction) when viewed in cross section.

[0092] like Figure 3 and Fig.11 As shown, the rectifying fin 73 is provided on the inner wall of the ventilation passage 71. The rectifying fin 73 is configured to include an upper rectifying fin 73a provided on the upper deformed portion 72a and a side rectifying fin 73b provided on the side deformed portion 72b.

[0093] like Fig. 9 As shown, the upper rectifying fin 73a is composed of, for example, three fins arranged at appropriate intervals L4 and L5 (for example, about 11 mm to 12 mm). The upper rectifying fin 73a on the inner side (left side) in the vehicle width direction is also arranged at the same interval L6 relative to the wall portion 72d of the ventilation path 71. When observed in cross section, the rear side (vehicle compartment side) of the upper rectifying fin 73a is formed to be inclined at an angle θ5 toward the inner side in the vehicle width direction relative to the front-to-back direction (ventilation direction). Therefore, the upper rectifying fin 73a can narrow the gap S1 between the front side of the upper rectifying fin 73a and the outer side wall of the ventilation path 71 in the portion of the ventilation path 71 formed into an inverted L shape, thereby preventing foreign matter C2 such as coins from intruding into the inner side of the ventilation path 71. The inclination angle θ5 of the upper rectifying fin 73a is Fig.10The side rectifying fins 73b shown in FIG. 7 are inclined at a larger angle than the inclination angle θ6 with respect to the horizontal direction. Therefore, the inner gap S2 formed by the upper rectifying fins 73a and the side rectifying fins 73b can be narrowed (see FIG. 7A ). Fig.11 ), thereby preventing foreign matter C2 such as coins from intruding into the inner side of the ventilation passage 71.

[0094] like Fig.10 As shown, the side rectifying fin 73b is formed in a manner that is inclined at an angle θ6 relative to the front-rear direction on the rear side (the vehicle compartment side). The side rectifying fin 73b is arranged in a manner that is offset (close to) the upper side of the side deformation portion 72b, and is arranged at a position that is closer to the top surface 71a than the inner bottom surface of the ventilation path 71. The top surface 71a of the ventilation path 71 close to the rear side (the inner side of the vehicle compartment) is inclined in a manner that decreases as it approaches the front side when viewed in a longitudinal section.

[0095] <<Flow path selection mechanism>>

[0096] like Figure 3 As shown, the flow path selection mechanism 8 is a switching device for selectively switching the flow path of the air-conditioned air delivered from the air-conditioning device (not shown). The flow path selection mechanism 8 can block the air-conditioned air delivered from the air-conditioning device (not shown) by operating the operating mechanism 4, or discharge it from the inner blow-out port 31, or discharge it from the outer blow-out port 32. The flow path selection mechanism 8 includes stop valves 81, 82 rotatably arranged in the inlet ports 60, 70, and a rotation mechanism (not shown) for being driven by the operating mechanism 4 to rotate the stop valves 81, 82 respectively.

[0097] The stop valve 81 is a component for switching the ventilation passage 61 for conveying conditioned air to the inner blow-out port 31 between a state in which air can be supplied and a state in which air supply is blocked. The stop valve 81 includes: a substantially plate-shaped valve core 81a for opening and closing the inlet 60; and a shaft portion 81b that rotatably supports the valve core 81a in the inlet 60 of the inner housing 6.

[0098] The stop valve 82 is a component for switching the ventilation path 71 for conveying conditioned air to the outer blow-out port 32 between a state in which air can be supplied and a state in which air supply is blocked. The stop valve 82 includes a substantially plate-shaped valve core 82a for opening and closing the inlet 70, and a shaft portion 82b that rotatably supports the valve core 82a in the inlet 70 of the outer shell 7.

[0099] The rotating mechanism (not shown) is a device for opening and closing the stop valves 81 and 82 in cooperation with the operation of the operating mechanism 4. The rotating mechanism (not shown) is composed of a gear mechanism or a link mechanism that transmits the action of the operating mechanism 4 to the shaft portions 81b and 82b to rotate the stop valves 81 and 82. The rotating mechanism (not shown) is interposed between the operating mechanism 4 and the shaft portions 81b and 82b of the stop valves 81 and 82.

[0100] <<The role of the rear vehicle structure>>

[0101] Next, refer to Figures 1 to 13 The operation of the air blowing device 2 according to the embodiment of the present invention will be described.

[0102] Air blowing device 2 Figure 2 and Figure 4 As shown, when the indicator 41a of the operating mechanism 4 is facing the direction of the closed mode 4a on the lower side, Figure 3 The stop valves 81 and 82 shown in the figure close the inlets 60 and 70. Therefore, even if the air conditioner (not shown) is in the activated state (ON state), the conditioned air is not blown out from the inside outlet 31 and the outside outlet 32.

[0103] When the air conditioning wind is discharged from the inner blow-out port 31 or the outer blow-out port 32, first, the air conditioning device (not shown) is started. Next, the operating unit 41 is turned clockwise to operate the indicator 41a to the position of the inner blow-out mode 4b or the outer blow-out mode 4c.

[0104] When the operating unit 41 is rotated 90 degrees clockwise from the closed mode 4a, the indicator 41a rotates to the position of the inner blow-out mode 4b. As a result, the flow path selection mechanism 8 rotates the stop valve 81 by a rotation mechanism (not shown) corresponding to the operating unit 41, so that the inlet 60 of the inner shell 6 is opened. When the inlet 60 is opened, the air-conditioned wind conditioned by the air conditioning device (not shown) is discharged from the inner blow-out port 31 into the vehicle interior through the passage, the inlet 60, the ventilation path 61, and the louver unit 5.

[0105] When the operation unit 41 is rotated 90 degrees clockwise from the inner blow-out mode 4b, the indicator 41a is rotated to the position of the outer blow-out mode 4c. As a result, the flow path selection mechanism 8 rotates the stop valve 81 by the rotation mechanism (not shown) corresponding to the operation unit 41, so that the inlet 60 of the inner shell 6 is closed, and at the same time, the stop valve 82 is rotated to open the inlet 70 of the outer shell 7. When the inlet 70 is opened, the air conditioning wind conditioned by the air conditioning device (not shown) is discharged from the outer blow-out port 32 to the vehicle interior through the passage, the inlet 70, the ventilation path 71, and the rectifying fins 73.

[0106] The outer blow-out port 32 is as follows Figure 6 As shown in FIG. 1 , since the upper blow-out area 32a is oriented obliquely upward toward the vehicle compartment side when viewed from the side, the air conditioning wind is discharged upward. Figure 7 As shown in FIG. 1 , since the side blowing area 32b is inclined toward the center side on the vehicle compartment side when viewed in cross section, the air conditioning wind is discharged toward the center side of the vehicle compartment. Figure 5 As shown, since the outer air outlet 32 ​​is formed in an inverted L shape, the conditioned air can be blown out to a wide range in an inverted L shape avoiding the occupant M.

[0107] The air blowing device 2 can be switched to three positions by rotating the indicator 41a of the operating mechanism 4 to the position of the closed mode 4a, the inside blowing mode 4b, or the outside blowing mode 4c.

[0108] As described above, the air blowing device 2 according to the embodiment of the present invention is as follows: Figure 2 to Figure 4 and Fig.11 As shown, the air blowing device 2 is arranged at both ends of the instrument panel 1 of the vehicle A in the vehicle width direction and blows out air. The air blowing device 2 includes: an inlet 70 for allowing air to flow into the air blowing device 2; an outer blow-out port 32 for blowing air into the room on the indoor side of the inlet 70; and a ventilation path 71, which is arranged between the outer blow-out port 32 and the inlet 70. The outer blow-out port 32 includes: an upper blow-out area 32a extending in the vehicle width direction; a side blow-out area 32b extending from the upper blow-out area 32b; and a ventilation path 71 extending from the upper blow-out area 32b to the side of the vehicle A. The outer end portion 72a in the vehicle width direction of the upper deformation portion 72a extends continuously downward, and the ventilation path 71 has a deformation portion 72 which deforms from the shape of the inlet 70 to the shape of the outer blow-out port 32 as it approaches the outer blow-out port 32, and the deformation portion 72 has: an upper deformation portion 72a extending in the vehicle width direction; and a side deformation portion 72b extending continuously downward from the outer end portion 72c in the vehicle width direction of the upper deformation portion 72a, and rectifying fins 73 are respectively provided on the upper deformation portion 72a and the side deformation portion 72b.

[0109] According to this configuration, the outer blow-out port 32 of the air blowing device 2 of the present invention includes an upper blow-out area 32a extending outward in the vehicle width direction, and a side blow-out area 32b extending downward from the outer end of the upper blow-out area 32a in the vehicle width direction, so as to be formed in an inverted L shape. Therefore, the outer blow-out port 32 can blow out air-conditioned wind to a wide range. In addition, the ventilation passage 71 is provided with a rectifying fin 73 on the upper deformed portion 72a and the side deformed portion 72b of the deformed portion 72 formed in an inverted L shape, so that the rectifying fin 73 can suppress the deflection of the air-conditioned wind and blow out uniform air-conditioned wind. In addition, the rectifying fin 73 is formed in the ventilation passage 71, and is therefore located in a position that is not easily seen from the passenger M, so that the appearance design can be improved and foreign matter can be prevented from intruding into the passage.

[0110] In addition, if Fig. 9 or Fig.11 As shown, the rectifying fin 73 includes an upper rectifying fin 73a provided on the upper deforming portion 72a, and the rear side of the upper rectifying fin 73a is inclined toward the vehicle width direction inner side with respect to the front-rear direction.

[0111] According to this configuration, the rear side of the upper rectifying fin 73a located at the upper deformed portion 72a extending in the vehicle width direction is inclined inwardly in the vehicle width direction relative to the front-rear direction, so that the range of blowing out the air-conditioned wind can be expanded inwardly in the vehicle width direction. Therefore, the upper rectifying fin 73a can blow out the air-conditioned wind from the outer blow-out port 32 to a wide range in the vehicle interior.

[0112] In addition, if Fig.10 As shown, the rectifying fin 73 includes a side rectifying fin 73b provided on the side deforming portion 72b, and the rear side of the side rectifying fin 73b is inclined upward with respect to the front-rear direction.

[0113] According to this configuration, the rear side of the side rectifying fin 73b is inclined upward with respect to the front-rear direction, so that the blowing range of the conditioned air can be expanded upward, and thus the conditioned air can be blown out from the outer air outlet 32 ​​into a wide range in the vehicle interior.

[0114] In addition, if Fig. 9 As shown, the inclination angle of the upper rectifying fin 73a relative to the horizontal direction is greater than the inclination angle of the side rectifying fin 73b relative to the horizontal direction.

[0115] According to this configuration, the upper rectifying fin 73a has a large inclination angle relative to the horizontal direction, so that the gap S1 on the inner side of the ventilation path 71 and the gap S2 on the inner side formed by the upper rectifying fin 73a and the side rectifying fin 73b can be narrowed in the portion formed into an inverted L shape (see Fig.11 ), thus preventing foreign matter from entering.

[0116] In addition, if Fig.10 As shown, the side rectifying fin 73b is provided so as to be offset to the upper side of the side deforming portion 72b.

[0117] According to this configuration, the side rectifying fins 73b are provided so as to be offset above the side deforming portions 72b, and thus the side rectifying fins 73b can be provided near the top surface 71a of the ventilation passage 71. Therefore, foreign matter can be prevented from intruding into the passage side.

[0118] In addition, if Figure 3 or Fig. 9As shown, a wall portion 72d is provided at the inner end portion in the vehicle width direction of the upper deforming portion 72a, and the wall portion 72d is formed to be inclined at substantially the same angle as the upper rectifying fin 73a with respect to the front-rear direction.

[0119] According to this configuration, the wall portion 72d of the upper deformed portion 72a of the ventilation passage 61 located at the inner end in the vehicle width direction is inclined relative to the front-rear direction at an angle substantially the same as that of the upper rectifying fin 73a, so that the air conditioning wind can be blown out to the inner side in the vehicle width direction of the vehicle interior in a wide range. In addition, when the air outlet 30 is observed from the vehicle interior, the inclination angle θ4 of the wall portion 72d is substantially the same as the inclination angle θ5 of the inner side in the vehicle width direction of the upper rectifying fin 73a, so that the appearance can be improved and the appearance design can be improved.

[0120] [Modifications]

[0121] It should be noted that the present invention is not limited to the above-mentioned embodiments, and various modifications and changes can be made within the scope of the technical concept. The present invention naturally includes the inventions after these modifications and changes.

[0122] For example, Figure 3 The rotating mechanism (not shown) of the flow path selection mechanism 8 shown is not limited to a gear mechanism or a connecting rod mechanism as long as it can rotate the stop valves 81 and 82 in accordance with the action of the operating mechanism 4 to close or open the inlet ports 60 and 70. For example, the rotating mechanism (not shown) may be an actuator such as an electric motor device or an electromagnetic working device that rotates the stop valves 81 and 82 based on an electrical signal from the operating mechanism 4 by setting the operating mechanism 4 as a switch such as a rotary switch, a slide switch, or a seesaw switch.
