Abstract

An adapter automatically controlling a power supply for an air conditioning apparatus by a sensor and individually formed outside of a power supply unit and an air conditioning apparatus, including a single or plural output terminals switching with an input power plug by a gas detecting control circuit installed in the adapter; a composite gas sensor operating the gas detecting control circuit; and a detection reference value preset volume controlling an operating range of this composite gas sensor.

Claims

1. An adapter automatically controlling a power supply for an air conditioning apparatus by a sensor and individually formed outside of a power supply unit and an air conditioning apparatus, said adapter comprising:

a single or plural output terminals switching with an input power plug by a gas detecting control circuit installed in the adapter;

a composite gas sensor operating the gas detecting control circuit; and

a detection reference value preset volume for controlling an operating range of said composite gas sensor.

3. An adapter according to claim 1, wherein the gas detecting control circuit includes a power supply circuit receiving an alternating current voltage through an internal line to drive a metal oxide semiconductor composite gas sensor, and supplying a heater voltage and a circuit voltage 10V

as direct currents;

a detecting circuit detecting a resistance variation of harmful gases with the size of voltages;

an amplifying circuit controlling a weak detecting signal to a size required for driving a relay or a light emitting diode;

a compensating circuit compensating a change in the resistance of the semiconductor gas sensor with an outer temperature;

a switching control circuit turning on or off an output signal on the basis of a preset density; and

an output circuit driving the light emitting diode, a buzzer, and the relay, and producing a power to a terminal through an internal line.

2. An adapter automatically controlling a power supply for an air conditioning apparatus by a sensor comprising:

an input power plug;

a plurality of output terminals;

a circuit board having a gas detecting control circuit driving a relay;
