Description

  The present invention relates to a seat blower used by being mounted on a vehicle seat.

In summer, when the amount of solar radiation is large and the outside air temperature becomes high, the temperature inside the car rises to a temperature far exceeding the outside air temperature. For this reason, when the outside air temperature becomes high, the air conditioner that air-conditions the interior of the automobile is cooled to cool the interior to a comfortable temperature. However, in summer when the amount of solar radiation is large and the outside air temperature is abnormally high, the cooling function of the air conditioner may not operate properly. It cannot be cooled to temperature. For this reason, especially when the occupant is seated on the seat for a long time, the temperature of the seating surface of the seat rises, and the portion of the occupant seated on the seat that is in contact with the seat is hot and uncomfortable.
