An induction heating apparatus is formed by connecting a plate or a rod made of good heat-transferring metal to the lower surface of an insulating plate, connecting a spring or a bimetal having shape-memorizing function to one end of the metallic plate or rod and providing a temperature displaying means at a corner portion or an operating part in the front surface of the insulating plate. The induction heating apparatus always displays a correct temperature in an insulating plate even at a high temperature in a cooking pot. Further, there is causing no shaving or peeling-off as seen in a paint in which change in color takes place depending on temperature and a danger of burn can be prevented.

An automobile ventilator which is a conventional ventilating device and a conventional air cleaning device combined into one. The ventilator structure has an air blowing passage opening into a passenger room of the vehicle. Through the air blowing passage comes out air blown by an impeller provided at the passage. There are further two passages to guide air to the impeller; one is a ventilation passage communicating outside the vehicle body while the other is a circulation passage opening into the passenger room. A damper is provided between the two passages in hinge fashion to selectively close either one of the two passages. This damper is controlled by manipulating the ignition switch such that the ventilation passage is closed on engine start whereas the circulation passage is closed when the engine is stopped. The impeller is driven alternately by first and second drive circuits. The first drive circuit is placed in an operative condition when the ignition switch is thrown to ON position whereas the second drive circuit is placed in an operative condition when the ignition switch is thrown to OFF position.

An air conditioning apparatus for car comprising: an air intake fan having internal and external air inlet ports and internal and external air change-over dampers; a heat exchanger for cooling and a heat exchanger for warming, both being arranged in series at the downstream of said air intake fan and in the direction substantially perpendicular to the direction of the air flow; a by-pass route provided above and in parallel with the heat exchanger for warming; and air mixing changer formed at the downstream of said heat exchanger for warming and said by-pass route; and an air blow-off port and a control damper for controlling direction of the air flow provided at the downstream of the air mixing chamber. The air intake fan, said heat exchanger for cooling, said heat exchanger for warming, said by-pass route, said air mixing chamber, said each air blow-off port, said each control damper and a water draining device are all installed in the same casing in the order as mentioned. The casing is made separable between said air intake fan and said heat exchanger for cooling, and said air intake fan is installed above a front deck portion enclosed by a cowl top outer panel and a cowl top inner panel or to the side of the engine room, and the remaining portion is installed in the vehicle cabin to be connected with said air intake fan.

A temperature control device for a vehicle cabin comprises a duct which communicatively connects, at least, inside the vehicle cabin and the external atmosphere; a damper provided within the duct and for shutting off flow of air inside and outside the vehicle cabin; drive means for driving the damper to open and close; a fan to produce the air flow within the duct; a fan motor to actuate and drive the fan; detecting means to detect temperature changes within the vehicle cabin; and a power source separately provided from an ordinary power source and for supplying power to the fan motor. A temperature increase within the vehicle cabin above a predetermined temperature is detected by the detecting means, then electric power is supplied to the fan motor from the separately provided power source, and the temperature within the vehicle cabin is controlled in utilization of the duct, in which the damper is in an open state.

An air-conditioner for an automobile is disclosed which is provided with a compressor adapted to be directly connected to the engine, the compressor being provided with two coaxial compressing cylinders each having a different displacement, whereby the cylinder having the smaller displacement is adapted to be always operated to carry out the dehumidification, while the cylinder having the larger displacement is adapted to be operated only when it is desired to air-condition the compartment by a change in its operation rate through the actuation of such as a slide valve.

Air-conditioner for an automobile

The disclosure describes a control device for the air-conditioning device for automobile in which a rolling piston type capacity changeable compressor which can be operated with a single piston cylinder by closure of one of two coaxial cylinders in the compressor by means of an opening and closing valve is used and selection is made as to whether single cylinder or double cylinders should be employed for operation of the compressor depending on a cooling load to be imposed on it.
