  By the way, an air-conditioning duct for supplying temperature-controlled air for air conditioning and a defroster duct for supplying temperature-controlling air for anti-fogging are connected to a common outlet member, and the air-conditioning temperature is controlled from the first outlet of the outlet member. In some cases, air is blown rearward toward the passenger, and temperature control air for preventing fogging is blown outward from the second outlet of the outlet member toward the door glass in the vehicle width direction.

  In such a case, the first outlet of the outlet member guides the temperature-controlled air toward the rear, whereas the second outlet of the outlet member guides the temperature-controlled air toward the outside in the vehicle width direction. Even when trying to mold the outlet member in the front-rear direction, the second outlet that is inclined outward in the vehicle width direction becomes an obstacle, requiring a mold with a complicated structure and increasing the cost. There is a problem to do.

  This invention is made | formed in view of the above-mentioned situation, and it aims at reducing the manufacturing cost of an outlet member provided with the 1st blowing outlet and the 2nd blowing outlet from which a blowing direction differs.

  In order to achieve the above object, according to the first aspect of the present invention, an air conditioning duct that guides the temperature-controlled air for air conditioning in the passenger compartment to the rear, and temperature-controlled air for preventing fogging of the side glass are provided. A defroster duct that guides backward; and an outlet member attached to an instrument panel cover, wherein the outlet member blows out the temperature-controlled air from the air-conditioner duct toward the rear; and the defroster duct And a second air outlet for blowing out the temperature-controlled air from the outside toward the outside in the vehicle width direction, wherein the first outlet opening of the air conditioner duct and the first outlet of the outlet member are directly connected In addition, the second outlet opening of the defroster duct and the second outlet of the outlet member are inclined in the vehicle width direction formed in the instrument panel cover. Air conditioning system characterized by being connected via a connecting duct portion that is proposed.

  According to the invention described in claim 2, in addition to the configuration of claim 1, temperature control from the connection duct portion is performed at a connection portion between the connection duct portion and the second outlet of the outlet member. A vehicular air conditioner is proposed, in which a rectifying member that deflects air outward in the vehicle width direction is disposed.

  The side outlet opening 11b of the embodiment corresponds to the first outlet opening of the present invention, and the outlet opening 12a of the embodiment corresponds to the second outlet opening of the present invention.

  According to the configuration of claim 1, the vehicle air conditioner guides the air conditioning duct for air conditioning in the passenger compartment to the rear, and guides the air conditioning air for preventing fogging of the side glass to the rear. A defroster duct and an outlet member attached to the instrument panel cover. The outlet member has a first outlet for blowing the temperature-controlled air from the air-conditioner duct to the rear, and the temperature-controlled air from the defroster duct. And a second outlet that blows out toward the outside in the direction.

  The first outlet opening of the air conditioner duct and the first outlet of the outlet member are directly connected, and the second outlet opening of the defroster duct and the second outlet of the outlet member are inclined in the vehicle width direction formed in the instrument panel cover. Since it is connected via the connecting duct portion, the temperature-controlled air from the defroster duct is deflected outside in the vehicle width direction by the connecting duct portion of the instrument panel cover, so that the temperature-controlled air is supplied to the vehicle width at the second outlet of the outlet member. There is no need to deflect outward in the direction. As a result, when the outlet member is molded, it is not necessary to integrally mold a portion corresponding to the connecting duct portion that is inclined outward in the vehicle width direction, and the outlet member can be die-cut in the front-rear direction. Thus, the mold structure is simplified, and the manufacturing cost of the outlet member can be reduced.

  According to the configuration of claim 2, since the rectifying member that deflects the temperature-controlled air from the connecting duct portion to the outside in the vehicle width direction is arranged at the connecting portion between the connecting duct portion and the second outlet of the outlet member. Not only can temperature-controlled air from the second outlet duct be smoothly guided toward the second outlet toward the outside in the vehicle width direction, but also dimensional tolerances and position errors of the first outlet duct, instrument panel cover, and outlet member. And the occurrence of a gap in the connecting portion between the connecting duct portion and the second outlet of the outlet member can be prevented, and the generation of noise and vibration due to leakage of temperature-controlled air can be suppressed.

The perspective view of an air-conditioner duct and a defroster duct. FIG. 2 is an enlarged view of part 2 of FIG. 1. The figure which shows the state which covered the exit opening of the air-conditioner duct and the defroster duct with the instrument panel cover. The figure which shows the state which attached the outlet member to the instrument panel cover. FIG. 5 is a sectional view taken along line 5-5 of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. In the present specification, the front-rear direction, the left-right direction (vehicle width direction), and the up-down direction are defined with reference to an occupant seated in the driver's seat.

  As shown in FIGS. 1 and 2, an air conditioner duct 11 and a defroster duct 12 are arranged inside an instrument panel (not shown) of the automobile. An air conditioner duct 11 connected to an air conditioner main body (not shown) in the center in the vehicle width direction includes a pair of rectangular center outlet openings 11a and 11a in the center in the vehicle width direction, and a pair of circles at both ends in the vehicle width direction. Shaped side outlet openings 11b and 11b (first outlet openings) are provided. Further, the defroster duct 12 having a central portion in the vehicle width direction connected to the air conditioner body includes a pair of arc-shaped outlet openings 12a and 12a (second outlet openings) at both ends in the vehicle width direction. Both the side outlet opening 11b of the air-conditioner duct 11 and the outlet opening 12a of the defroster duct 12 which are arranged adjacent to each other are opened rearward, and the opening ends thereof are cut by a plane according to the demands of a technical skill. Yes.

  As shown in FIGS. 3 to 5, the air-conditioner duct 11 and the defroster duct 12 are housed inside an instrument panel cover 13 that covers the instrument panel, and an outlet member 14 is attached to an opening formed in the instrument panel cover 13. The The outlet member 14 integrally formed of synthetic resin includes a circular first blowing port 14a on the inner side in the vehicle width direction and an arcuate second blowing port 14b on the outer side in the vehicle width direction. 14a blows out the temperature-controlled air from the side outlet opening 11b of the air-conditioner duct 11 toward the passenger in the passenger compartment, and the second outlet 14b sends the temperature-controlled air from the outlet opening 12a of the defroster duct 12 to the front door. It blows diagonally toward the door glass shown in the figure and rearward in the vehicle width direction. The first air outlet 14a and the second air outlet 14b are provided with louvers for adjusting the direction of the temperature-controlled air.

  The first outlet 14a of the outlet member 14 is integrally provided with a cylindrical guide portion 14c that extends forward, and the front end of the guide portion 14c extends in the front-rear direction to the rear end of the side outlet opening 11b of the air conditioner duct 11. Mating. On the other hand, the second outlet 14 b of the outlet member 14 does not have a portion corresponding to the guide portion 14 c and is separated from the outlet opening 12 a of the defroster duct 12. A connecting duct portion 13 a covered with the outlet member 14 is integrally formed at the outer end portion of the instrument panel cover 13 in the vehicle width direction. The front end 13 b of the connecting duct portion 13 a having an arcuate cross section is fitted into the outlet opening 12 a of the defroster duct 12, and the rear end 13 c is abutted against the second outlet 14 b of the outlet member 14.

  The direction in which the connecting duct portion 13a of the instrument panel cover 13 extends is deviated from the front-rear direction, the upstream side (front end 13b side) is biased inward in the vehicle width direction, and the downstream side (rear end 13c side) is biased outward in the vehicle width direction. doing. Therefore, the guide part 14c of the outlet member 14 extending in the front-rear direction is not parallel to the connecting duct part 13a inclined in the vehicle width direction (see FIG. 5).

  An extension portion 13d extends rearward from the inner end in the vehicle width direction of the rear end 13c of the connecting duct portion 13a, and a rectifying member 15 made of synthetic resin is attached to the rear end of the extension portion 13d. The rectifying member 15 is an arcuate member that follows the shape of the rear end 13c of the connecting duct portion 13a, and a slit 15a that opens toward the front is fitted and fixed to the extension portion 13d. A rectifying surface 15b that is inclined outward in the vehicle width direction is formed on the outer surface of the rectifying member 15 in the vehicle width direction, and a seal that contacts the inner surface of the outlet member 14 adjacent to the second outlet 14b at the rear end of the rectifying surface 15b. A surface 15c is formed.

  Next, the operation of the embodiment of the present invention having the above configuration will be described.

  Part of the temperature-controlled air supplied from the air-conditioner body to the air-conditioner duct 11 flows into the guide portions 14c and 14c of the outlet member 14 from the pair of side outlet openings 11b and 11b at both ends in the vehicle width direction, and the guide portions 14c and 14c. The vehicle interior is air-conditioned by blowing backward from the first outlets 14a, 14a at the rear end toward the occupant. Further, part of the temperature-controlled air supplied from the air conditioner body to the defroster duct 12 flows into the connecting duct portions 13a and 13a of the instrument panel cover 13 through the pair of outlet openings 12a and 12a at both ends in the vehicle width direction, and the connecting duct portion 13a. , 13a is blown obliquely rearward from the second outlets 14b, 14b of the outlet member 14 connected to the rear end of the outlet member 14, thereby preventing fogging of the door glass.

  From the viewpoint of design, the outlet member 14 is integrally provided with a first air outlet 14a that blows out temperature-controlled air for air conditioning and a second air outlet 14b that blows out air-conditioned air for anti-fogging, but the first air outlet 14a. Has a problem in that it is difficult to mold the outlet member 14 when the outlet member 14 is molded.

  That is, since the cylindrical guide portion 14c integrally extends forward from the first blowout port 14a of the outlet member 14, the die cutting direction when the outlet member 14 is molded is inevitably the front-rear direction. At this time, if the cylindrical guide portion extends obliquely forward from the second outlet 14b of the outlet member 14 that blows the temperature-controlled air obliquely backward, the guide portion inhibits the outlet member 14 from being punched. become.

  However, according to the present embodiment, the second outlet 14b of the outlet member 14 does not include a guide portion that extends obliquely forward, and the connecting duct portion 13a that functions as the guide portion is different from the outlet member 14. Since it is formed integrally with the instrument panel cover 13 which is a member, the outlet member 14 can be punched in the front-rear direction without complicating the structure of the mold, and the manufacturing cost of the outlet member 14 is reduced.

  Further, since the opening end of the outlet opening 12a of the defroster duct 12 is cut by a plane according to the demands of the engineering, it is not possible to directly connect the outlet opening 12a to the inclined second outlet 14b of the outlet member 14. Although difficult, since the connecting duct portion 13a of the instrument panel cover 13 is interposed between the outlet opening 12a of the defroster duct 12 and the second outlet 14b of the outlet member 14, the outlet opening 12a and the outlet member 14 of the defroster duct 12 are provided. The second outlet 14b can be easily connected. Moreover, since the connecting duct portion 13a and the outlet member 14 of the instrument panel cover 13 are separate members, the connecting duct portion 13a is formed obliquely so that the temperature-controlled air from the outlet opening 12a of the defroster duct 12 is outward in the vehicle width direction. It can be deflected and blown obliquely from the second outlet 14b of the outlet member 14 toward the door glass.

  By the way, even if the connecting duct portion 13a of the instrument panel cover 13 is connected to the second outlet 14b of the outlet member 14, it is difficult to completely seal the connecting portion due to the dimensional tolerance and position error of each member. There is a problem that the temperature control air leaks from the gap and causes noise and vibration.

  However, according to the present embodiment, since the rectifying member 15 inserted and attached so as to cover the end of the extension portion 13d of the connecting duct portion 13a of the instrument panel cover 13 is brought into contact with the inner surface of the outlet member 14, The gap between the duct portion 13a and the outlet member 14 can be blocked by the seal surface 15c of the rectifying member 15 to prevent the temperature-controlled air from leaking, and the conditioned air from the connecting duct portion 13a can be prevented by the rectifying surface 15b of the rectifying member 15. Can be further deflected outward in the vehicle width direction and blown out from the second blow-out port 14b toward the door glass. As described above, since the rectifying member 15 has both the rectifying function of the temperature-controlled air and the sealing function, the number of parts can be reduced.

  The embodiments of the present invention have been described above, but various design changes can be made without departing from the scope of the present invention.

  For example, the side glass of the present invention is not limited to the door glass of the embodiment, and may be a front quarter glass.

  Further, the entire instrument panel cover 13 does not need to be formed of a single member, and a portion to which the outlet member 14 is attached may be divided.
