An air blower for a vehicle, which is provided on a ceiling of the vehicle and includes an air outlet that blows to a seat side, and an air filter that rotates so as to be able to face and separate from the air inlet or the air outlet. Rotating the blower at a high speed when rotated to a position away from the mouth or the outlet,
The present invention relates to a blower device for a vehicle, comprising a blower rotation control circuit for rotating the blower at a low speed when the blower is rotated to a facing position.

[Action]

Since the vehicle air blower of the present invention has the above configuration,
The cool air blown from the air conditioner of the automobile to the front seat side is sucked into the suction port and blown from the blower port to the rear seat side by the blower, so that the cool air can be blown to the passenger in the rear seat. In addition, since the air blower is equipped with an air filter that has a rotation mechanism that can be separated from the suction port or the air outlet, it can be blown directly to the rear seat when the air filter is rotated to a position that separates from the suction port. When cooling is performed and the air filter is rotated to a position where it comes into contact with the suction port, the indoor air sucked from the suction port is removed and cleaned by the air filter,
It is blown out from the outlet. When the rear seat cooling is to be performed, when the air filter is released, the control circuit that detects it releases the blower at high speed to blow the air at high speed. This gives the occupants in the rear seats a comfortable cooling feeling. When attempting to purify the air, when the air filters are faced to each other, the control circuit which detects the air filters rotates the blower at a low speed to blow the air at a low speed. As a result, the dust removal efficiency of the air filter can be improved, the collected dust can be prevented from falling off, and the cleanliness of the indoor air can be improved.
