Document Type and Number:
Japanese Patent JPS5830511
Kind Code:
B2
Abstract:
PURPOSE:To protect a compressor motor by constructing a controlling system of a manual switch, a thermo-detecting circuit, a main operation circuit, a timer circuit, a current intercepting means, a sub-operation switch, and a means to supply current to a fan motor. CONSTITUTION:When a manual switch 11 is connected, a condenser 12 is charged, and a direct current Ea is generated in a line 33 to be supplied to a main operation circuit 3, a thermo-detecting circuit 4, a timer circuit 5, an OR gate 7, and an AND gate 6. An integration circuit is formed by a resistance 13 and a condenser 14 for delaying the rising of the voltage in a line 35. Output signals of the AND main operation circuit 3 and the timer circuit 5 are fed to the AND gate 6 and the OR gate 7, while the output signal of the thermo-detecting circuit 4 is fed to the AND gate 6. An integration circuit is formed by the resistance 13 and the condenser 14 for delaying the rising of the voltage in the line 35. a compressor motor is protected by this circuit construction.
