Title:
AUTOMATIC AIR-CONDITIONING DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JPS621613
Kind Code:
A
Abstract:
PURPOSE:To make it possible to obtain a volume of blow-out air which is optimum for the passengers with a simple manipulation, by providing an air- volume reducing means which delivers an instructing signal for reducing the blow-out air volume automatically set in accordance with the manipulation of switches. CONSTITUTION:There is provided an air volume setting means 3 which controls the rotational speed of a blower motor 1 in a range from its maximum speed to its minimum speed by four stages to set a necessary volume of blow-out air, and which is composed of three resistors 5-a-5-c and four relays 7, 9, 11, 13. Further, there is provided an air volume setting means for setting an air volume obtained by subtracting a predetermined amount from the above- mentioned necessary blow-out air volume, which is composed of three relays 17, 19, 21 and a switch 23 for controlling the rotational speed of the blower motor 1 to decrease the same by one stage upon turn-on manipulation. Further, there is provided an air volume computing means 25 for calculating the necessary blow-out air volume in accordance with output signals from inside and outside air temperature sensors, a solar radiation sensor, etc. and issuing a control signal from any one of terminals A through D.
