摘要： PURPOSE:To defrost automatically a wind shield quickly and prevent it from being frosted for effecting comfortable air conditioning without using a compressor by controlling not only an amount of blow-off air from a defroster plenum but also a ratio of inside air to outside air for air conditioning. CONSTITUTION:When it is detected by a frost sensor 16 that a wind shield is frosted, an air plenum change-over damper 6 is controlled in such a way that an amount of blow-off air from a defroster plenum 1a is increased or decreased depending on the condition of frosting. And an inside/outside air change-over damper 3 is simultaneously controlled in such a way that the opening is changed over. Accordingly, a volume of air from the defroster plenum 1a is increased as the condition of frosting on the wind shield F is degraded, besides, a volume of suction air is increased to reduce the humidity of blow-off air. An electronic control circuit 13 is adapted to control the above mentioned operations automatically for reducing suction air from the outside as the wind shield is defrosted so as to eliminate a need for an actuation of an air compressor of an air conditioner without degrading the efficiency of air conditioning.

摘要： PURPOSE:To eliminate a complicated link mechanism, by a method wherein two damper members, each having a sectional shape equal to that of an open air introduction flow passage, are situated to a switch damper, and the two members are securely attached to a single pivot. CONSTITUTION:damper 40 has two damper members 42A and 42B, secured to a single pivot 41, and the two members 42A and 42B cross each other at angle of 90. The shape of each of the damper members 42A and 42B is approximately uniformized with the sect. ional shape of an inner air and open air introduction flow passage. Thus, only through rotation of the single pivot 41 and driving of a damper 40, ventilation of inner air, intake of the open air, and switching to ventilation are practicable. This constitution elimiates the need to interlock the damper 40, located in each communicating part between flow passages, using plural complicated link mechanisms, and enables simple execution of switching through the working of a simple control means.

摘要： PURPOSE:To make even fogging on a windshield alone eliminable, by constituting a fog criterion so as to be corrected to a yet smaller auxiliary reference value at a time when the rider detector installed in a rear seat detects no rider. CONSTITUTION:When a rear window Wr is fogged, a judging device 20 operates, and a microcomputer 25 processes each inputted signal out of rider sensor 22 and a humidity sensor 21 according to the specified program, and if the fog on the rear window Wr goes beyond the specified reference value A, it outputs a dehumidifying signal via an electrical control unit 17, driving a com pressor 12 and switching a selector damper 16, thus it performs dehumidification. And, when no driver exists in a rear seat and a rider sensor 22 detects no rider, the microcomputer 25 sets the reference value A to be lower as much as the specified value DELTAA, setting an auxiliary reference value A'. And with this auxiliary reference value A', a fog judgment takes place. With this constitu tion, even when a windshield alone is fogged, the dehumidification is perform able, thus driving safety is improvable.

摘要： PURPOSE:To prevent the generation of ozone and to stop the operation of an air cleaner automatically by constituting the air cleaner in such a manner that a sensor detects the increase of the ozone concn. caused by a decrease of suspended particles in the air then the power source control part stops the generation of the high voltage in a power source part. CONSTITUTION:A high positive DC voltage is supplied to an electric discharge electrode 6 and a high negative DC voltage to a dust precipitation electrode 9 when electric current is supplied to the power source part 11. Positive ion is then generated near the electrode 6 and is attracted toward a counter electrode 7 and the electrode 9. Ion stream is generated at this time and the suspended particles move as well to stick and deposit onto the electrode 9. The oxygen in the air is converted to ozone by the corona discharge, but the ozone oxidizes and cracks if there are the suspended particles. The ozone concn. increases when the air is thereby cleaned. Such increase of the ozone concn. is detected by the sensor 14 and the supply of the current to the power source part 11 is automatically interrupted. The air cleaner is thus adequately operated.

摘要： PURPOSE:To surely prevent exhaust gas from a Diesel-engine from entering into the passenger's compartment of a vehicle, by automatically changing over inside and outside air change-over dampers when the exhaust sound of the engine is coincident with an exhaust sound characteristic previously stored in a memory and when the former is not coincident with the latter. CONSTITUTION:Unidirectional type microphones 22-24 are attached to the front section of a vehicle with their sound sensing sections being directed to the right and left sides, and front and rear sides of the vehicle, for detecting exhaust sound from a Diesel-engine positioned in the front section of one side section of the vehicle. Further, when an exhaust sound detection signal is coincident with an exhaust sound characteristic stored in a memory means in a microcomputer 26, a drive mechanism 27 changes over both change-over dampers 21, 21 into an inside air introducing position (indicated by a broken line) at which an inside air introduction port 11b is opened. Meanwhile if they are not coincident with each other, the drive mechanism 27 changes over both dampers 21, 21 into an outside air introducing position (indicated by a solid line) at which an outside air introducing port 11a is opened.
