Description

  The present invention relates to a seat surface cooling / heating device for cooling / heating a seat surface on the front side of a vehicle seat including a seat cushion and a seat back.

As a conventional device for cooling and heating a vehicle seat, heat generated by a heat source having a cooling or heating function is transferred to a temperature-adjusted portion serving as a seat surface via a heat conduction portion, and is blown from a blower. It is known to cool and heat the seat surface by blowing cold / warm air from a large number of blowing holes formed on the entire surface of the temperature controlled portion through the convection portion (for example, Patent Document 1).
JP 2003-42590 A

  However, in such a conventional seat surface cooling / heating device, since the heat of one heat source is transferred to the temperature-adjusted portion via the heat conducting portion, the temperature of the heat conducting portion is close to the heat source. There is a problem that the temperature is high at the portion and low at the portion far from the heat source, and temperature unevenness occurs in the temperature-adjusted portion, that is, the sheet surface.

  In addition, even when the cool air of the blower is blown out from the blowout holes of the temperature controlled portion to cool and heat the seat surface, the amount of air blown from the blowout holes is changed by the blowout holes depending on the direction of the wind blown from the blower. Therefore, there is still a problem that temperature unevenness occurs on the sheet surface.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a seat surface cooling / heating device for a vehicle seat capable of suppressing the occurrence of temperature unevenness on the seat surface to be air-conditioned.

Can do.

  At this time, since the heat exchange medium of the seat outside heat exchanger 12 circulates through the medium flow paths 11Ap and 11Bp of the seat cushion side heat exchanger 11A and the seat back side heat exchanger 11B, the seat cushion side heat exchanger 11A and The seat back side heat exchanger 11B can be uniformly cooled as a whole, and consequently the seat surfaces 2a and 3a can be uniformly cooled.

  When the vehicle interior temperature is low due to cold weather or the like, the seat cushion side heater 14A and the seat back side heater 14B incorporated in the seat cushion side heat exchanger 11A and the seat back side heat exchanger 11B are provided. By operating, the seat cushion side heater 14A and the seat back side heater 14B can be uniformly heated.

  Further, in the present embodiment, the seat cushion side heater 14A and the seat back side heater 14B, that is, their heating wires 14Ar and 14Br are passed through the medium flow of the seat cushion side heat exchanger 11A and the seat back side heat exchanger 11B. Since the paths 11Ap and 11Bp are removed, the heat of the seat cushion side heater 14A and the seat back side heater 14B is not easily taken away by the heat exchange medium in the fluid flow paths 11Ap and 11Bp. The quick heating effect of the seat surfaces 2a and 3a can be enhanced when the back heater 14B is operated.

  Furthermore, the seat cushion side heat exchanger 11A and the seat back side heat exchanger 11B form the first to third flexible sheets 17a, 17b, 17c and the medium flow paths 11Ap, 11Bp therebetween. However, the flow path collapses due to the occupant pressure to the in-seat heat exchanger and the outward path with respect to the in-seat heat exchanger is made downward in the gravitational direction. Since the medium flow paths 11Ap and 11Bp can be set in a crushed state when the heat exchange medium is drained and not supplied to the reservoir tank, the vehicle can be seated on the vehicle seat 1 without a sense of incongruity and the heat exchange medium is supplied. The medium flow paths 11Ap and 11Bp can be expanded to smoothly distribute the medium.
