PURPOSE:To prevent a decline in cooling capability of a car air conditioner without a water valve by arranging close mutual magnetic adhesion of an air mix sub door and a heater core at the maximum cooling position of a heater control lever. CONSTITUTION:When a heater control lever 8a is set to the maximum cooling position C, an air mix door 6 and an air mix sub door 7 are completely closed through a wire cable 8b, while air suctioned through a floor 3 passes through an evaporator 4, and after being turned into cooled air, blows out into the car. And when the heater control lever 8a enters backlash scope U, the switch 8c is turned on, magnetizing an electromagnet 5b. Accordingly, the suctioned member 7a of the air mix sub door 7 is drawn to the electromagnet 5b, and the sub door 7 and a sealing frame 5a adhere closely, thereby sealing space between a heat core 5 and the sub door 7. Based on this arrangement, leakage of warm air here can be prevented, so that the cooling effect of the equipment is improved. |
