Description

  The present invention relates to an exhaust structure of an air conditioning unit mounted on a vehicle seat.

Conventionally, an air conditioning unit mounted on a vehicle seat is known (for example, Patent Document 1). The air conditioning unit generally has a Peltier heat converter and a blower. The blower sucks air in the passenger compartment through an intake duct connected to the leeward side and sends air to a blower duct connected to the leeward side. The Peltier heat converter is provided on the air duct side and adjusts the temperature of the air by heating or cooling the air. The temperature-adjusted air is blown to the vehicle seat through a blowout duct connected to one side of the Peltier heat converter, and blown to the passenger side through the seat. An exhaust duct is connected to the other side of the Peltier heat converter, and exhaust (heat) that is no longer needed by the Peltier heat converter flows through the exhaust duct. The exhaust is discharged outside the vehicle through an exhaust port on the vehicle body side to which an exhaust duct is connected.

  As shown in FIGS. 2 and 3, a blowout duct 7 is connected to one side of the Peltier heat converter 3, and an exhaust duct 5 is connected to the other side. Accordingly, the air in the passenger compartment is sucked by the blower 2 from the opening 6a of the intake duct 6 and is sent to the Peltier heat converter 3 provided on the air duct 4 side. Then, the temperature-controlled air by the Peltier heat converter 3 is blown out to the seat 13 side through the blowout duct 7, and unnecessary air (exhaust gas) is discharged through the exhaust duct 5.

  The blowout duct 7 is connected to an air passage 13f formed in the pad 13c of the seat cushion 13a as shown in FIG. The air passage 13f is disposed on the lower surface of the slab urethane 13d disposed on the upper surface of the pad 13c. A plurality of through holes 13g and 13h are formed in the slab urethane 13d and the skin 13e of the seat 13, and the temperature-adjusted air is blown out to the passenger side through the through holes 13g and 13h.

  The connection part 5a of the exhaust duct 5 is connected to a center console 14 which is an interior product as shown in FIGS. The center console 14 is disposed between the left and right seats 13 as shown in FIGS. The center console 14 has a storage recess 14c for storing a juice bottle or the like on the front side, and an exhaust port 14b on the side. An exhaust port member 8 to which the exhaust duct 5 is connected is attached to the exhaust port 14b. As shown in FIG. 3, the wall surface of the center console 14 has a plurality of holes 14a extending in the longitudinal direction in the wall surface, and one of the holes 14a (14a1) is used as an exhaust passage.

  As shown in FIGS. 4 and 6, the exhaust port member 8 has a mounting plate portion 8d, a cylindrical portion 8a, and an overhang (fin) 8b. The mounting plate portion 8 d is attached to the constituent wall surface of the storage recess 14 c of the center console 14. An exhaust port 14b is penetrated through the wall surface of the housing recess 14c, the cylinder part 8a is inserted through the exhaust port 14b, and the cylinder part 8a projects from the exhaust port 14b side to the seat 13 side. An opening window 8e that opens to the hole 14a1 is formed on the side surface of the cylindrical portion 8a. The overhang barb 8b projects from the lower edge of the cylinder portion 8a toward the exhaust duct 5 and overlaps with the lower position of the exhaust duct 5. Side portions 8c are erected on both side edges of the overhang barb 8b.

  As shown in FIGS. 4 and 7, an exhaust leakage prevention member 9 is provided between the exhaust port member 8 and the exhaust duct 5. The exhaust leakage prevention member 9 is made of an elastic material such as resin or rubber, and includes an outer skin side leakage prevention piece 9a and a duct side leakage prevention piece 9b. The skin side leakage preventing piece 9a has an attachment portion 9a1 and an extension portion 9a2 extending downward from both end edges of the attachment portion 9a1. The attachment portion 9a1 is bonded to the lower surface of a resin attachment plate 16 sewn on the skin 13e of the sheet 13. The duct side leakage preventing piece 9 b is bonded to the lower surface of the exhaust duct 5.

  As shown in FIGS. 2 and 5, the vehicle body 11 has a parting portion 11 b erected on the rear side of the seat 13. An exhaust port 11a is formed in the parting portion 11b, and the exhaust port 11a is connected to the hole 14a of the center console 14 by piping. Therefore, the exhaust from the air conditioning unit 1 is discharged into the seat back space 18 through the exhaust duct 5, the hole 14 a of the center console 14, and the exhaust port 11 a of the vehicle body 11. The seat back side space 18 is formed between the parting portion 11 b and the trunk 17, and the exhaust is discharged outside the vehicle through the seat back side space 18.

  The procedure for assembling the vehicle 10 is to first mount the air conditioning unit 1 and the ducts 4 to 7 on the seat 13 (see FIG. 3). Next, the seat 13 is mounted on the vehicle body 11, and then the center console 14 is mounted on the vehicle body 11. Subsequently, the exhaust port member 8 is attached to the center console 14, and the exhaust leak preventing member 9 is elastically deformed by the exhaust port member 8 and the exhaust duct 5. As a result, as shown in FIGS. 4, 8, and 9, the duct side leakage preventing piece 9 b is elastically deformed by being sandwiched between the overhanging rod 8 b and the exhaust duct 5. The skin side leakage preventing piece 9a is pushed and elastically deformed by the upper portion of the cylindrical portion 8a. The skin side leakage prevention piece 9a covers the upper side of the connecting portion 5a of the tube portion 8a and the exhaust duct 5, thereby closing the space between the tube portion 8a and the skin 13e and between the connecting portion 5a and the skin 13e.

  The procedure for attaching and detaching the seat 13 from the vehicle body 11 in order to maintain the air conditioning unit 1 and the like first removes the seat 13 from the vehicle body 11 together with the air conditioning unit 1 and the ducts 4 to 7. At this time, as shown in FIG. 4, the exhaust duct 5 moves above the exhaust port member 8 through the opening 8 f positioned above the overhanging rod 8 b of the exhaust port member 8. Therefore, the exhaust duct 5 is detached upward from the exhaust port 14b side without performing an operation of removing the piping.

  The procedure for attaching the seat 13 to the vehicle body 11 after the maintenance of the air conditioning unit 1 and the like is as follows. First, as shown in FIGS. As a result, the exhaust duct 5 passes through the opening 8f of the exhaust port member 8 and approaches the overhanging rod 8b. The exhaust duct 5 cooperates with the overhang barb 8b of the exhaust port member 8 to elastically deform the duct side leakage preventing piece 9b. As a result, the space between the exhaust duct 5 and the overhang bar 8b is closed by the duct side leakage preventing piece 9b.

  At the same time, as shown in FIGS. 4 and 8, the sheet 13 cooperates with the cylindrical portion 8 a of the exhaust port member 8 to elastically deform the skin side leakage preventing piece 9 a. Thereby, the space between the skin 13e and the cylindrical portion 8a is closed by the skin side leakage preventing piece 9a. And it elastically deforms so that the extension part 9a2 of the skin side leak prevention piece 9a spreads below, and it follows the side surface of the cylinder part 8a. Therefore, the exhaust leak prevention member 9 prevents the exhaust leak from being connected to the exhaust port member 8 and the exhaust duct 5, which are portions that cannot be seen from the indoor side by the seat 13.

  As described above, the exhaust leakage prevention member 9 is provided on the exhaust duct 5 side as shown in FIGS. Therefore, by mounting the seat 13 on the vehicle body 11 side, exhaust leakage from between the exhaust duct 5 and the exhaust port 14b is reduced. Therefore, the seat 13 can be attached to and detached from the vehicle body 11 without connecting or disconnecting the exhaust duct 5 and the exhaust port 14b.

  Further, as shown in FIG. 4, an exhaust port 14b is formed in the center console 14, and an exhaust port member 8 is provided in the exhaust port 14b. The exhaust port member 8 has a protruding rod 8b. Therefore, the exhaust duct 5 is connected via the exhaust port member 8 of the center console 14. Therefore, the position where the exhaust duct 5 is connected can be set to a desired position. Further, the exhaust port member 8 has an overhanging rod 8b, and the overhanging rod 8b can elastically deform the exhaust leakage preventing member 9 in cooperation with the exhaust duct 5.

  The exhaust leakage prevention member 9 has a skin side leakage prevention piece 9a. Therefore, the leakage leakage from the exhaust duct 5 and the sheet 13 and between the exhaust port 14b side and the sheet 13 can be reduced by the skin side leakage preventing piece 9a.

  Moreover, this form has the attachment board 16 sewn on the skin 13e, and the skin side leak prevention piece 9a is adhere | attached on the attachment board 16. FIG. Therefore, the skin side leakage preventing piece 9a can be securely and easily attached to the skin 13e via the mounting plate 16.
