At this time, by operating the air conditioner blower unit and the seat blower unit 430 for supplying air to the automotive air conditioner 200 using the solar cell device at the same time can maximize the effect of the sheet surface temperature drop.

Next, the principle of the cooling and heating operation of the air conditioner of the vehicle seat configured as described above will be described. In the following description, the operation principle of the air conditioner 200 is the same as the general principle, so a description thereof will be omitted, and will be described based on the cooling and heating operation of the vehicle seat which is the core of the present invention.

4 and 5, when sheet cooling is performed, cold air (when dotted arrows) are introduced into the connection duct 310 through the cold air introduction duct 370.

The cold air introduced through the cold air inlet duct 370 is rotated by the sheet air discharge temperature control door 413 provided in the connection portion C of the hot air inlet duct 390 and the connection duct 310. It is introduced into the blower case 433 through the suction port 431a by the rotational force of the fan 435 of the seat blower unit 430. The air flowing in the direction of the rotation shaft 435a of the fan 435 through the suction port 431a is ejected in the centrifugal direction from the rotation center of the fan 435 and is discharged to the driver side discharge port 433a and the tidal side discharge port 433c. . Thereafter, after the cool air flows into the spaces 331, 333, 351, and 353 in the driver side seat 330 and the tidal side seat 350 through the seat connection ducts 461 and 463, through the discharge holes 331a, 351a, 333a, and 335a. Cooling of the seats 330 and 350 is performed by being discharged toward the buttocks and the back of the occupant.

If the passenger does not ride on the tidal-side seat 350, the door member 433 provided at the tidal-side discharge port 433c is rotated to close the tidal-side discharge port 433c to discharge cold air only to the driver side seat 330. You can do that.

When sheet heating is performed, the warm air (when solid arrow) heated through the heater core 215 is introduced through the inlet 391 of the warm air introduction duct 390 and flows into the connection duct 310. At this time, the sheet air discharge temperature control door 413 provided in the connection portion C of the hot air introduction duct 390 and the connection duct 310 is rotated in the dotted line display state of FIG. 4 to introduce the air introduced into the hot air introduction duct 390. Flows into the connecting duct 310. Since the operation of supplying the warm air flowing in the connection duct 310 to the seats 330 and 350 is the same as the aforementioned cold air supply principle, detailed description thereof will be omitted.

As described above, when cooling or heating the driver's side and the assistant's side sheets 330 and 350, the temperature of the cold or warm air is not the desired temperature. That is, when the occupant feels that the temperature of the cold wind is too cold, the actuator 411 is driven by the control of a controller (not shown) when the operating condition (not shown) is selected to completely block the hot air introduction duct 390 side. The air discharge temperature control door 413 is opened to some extent to introduce the warm air heated through the heater core 215 into the connection duct 310. The introduced warm air is joined with the cold air introduced from the cold air introduction duct 370 to increase the temperature of the cold air so as to cool the driver's side and the tidal side seats 330 and 350 at a desired temperature.

On the other hand, when the occupant feels that the temperature of the warm air is too high in the seat heating operation, when the air conditioner 200 is not in the maximum heating state, the air introduced from the cold wind inlet duct 370 is transferred to the warm air inlet duct 390. Since the temperature is relatively lower than the flowing air, the door member 236 provided at the inlet 371 side of the cold air inlet duct 370 of FIG. 4 is opened to connect the cold air through the cold air inlet duct 370. By joining the warm air introduced through the warm air inlet duct 390 to lower the temperature of the warm air, the passenger side and the tide side seats 330 and 350 may be heated to a desired temperature.

Alternatively, when the air conditioner 200 is at the maximum heating state, that is, when the temperature control door 217 is in the dotted line state of FIG. 4, the opening and closing degree of the sheet air discharge temperature control door 413 is adjusted to control the connection duct 310. The heating temperature can be controlled by adjusting the amount of warm air supplied to).
