When a person 13 sits on a chair and places the back of his or her head 14 on the seat 15, the seat 15 touches the front surface 1 of the evaporator.
7, the back of the head 14 is in close contact with or close to the seat 15
The foot 18 is cooled through the foot plate 5 and warmed by placing the foot 18 on the foot plate 5. When the head 14 is separated from the seat 15, the seat 15 is moved to the front surface 1 of the evaporator 11.
It is starting to move away from 7 again. Since the evaporator 11 is covered with the sheet 15 so as to be thermally closed, an excessive load is not applied to the compressor 8, so that the life of the compressor can be extended. Reference numeral 19 denotes a drain pipe, through which dew on the evaporator and water accumulated in the container 16 flow into a tray 20 provided on the compressor 8, where it is evaporated by the heat of the compressor 8 and is eliminated, at the same time cooling the compressor 8. do. It goes without saying that the evaporator 11 does not have a bent shape as described above, but other shapes in which the front surface touches the head are also included in the present invention. The heat dissipation pipe 7 is attached closely to the back surface of the foot plate 5 to conduct heat from the pipe 7 to the foot plate 5 with good heat transfer, and the air flow 21 blows up as heat convection through the many through holes 6, and the foot part 18 is heated. The compressor 8 is heated sufficiently, and the heat dissipation pipe 7 is sufficiently radiated.
It is now possible to reduce the load on the vehicle and extend its lifespan. In addition, as shown in the figure, it is preferable that the foot plate 5 is placed at a higher position than the compressor 8 or at the same level as the compressor 8, and is inclined. This prevents the lubricating oil for the compressor mixed with the refrigerant from accumulating in the heat radiation pipe 7 and not reaching the compressor 8, causing the compressor to seize. is prevented. The compressor 8 is provided using the space between the legs 22 under the seat of the chair 1. The compressor 8 is attached and mounted on the end portion 23 of the foot plate 5 with bolts or the like, and the foot plate 5 is loosely attached to a beam 24 extending between the legs 22 by a spring 25.
