REFRIGERATOR

PURPOSE:To reduce starting time noise, and enable a refrigerator inside temperature to reach a setting temperature speedily by starting a compressor after the minimum starting time is learned in order to minimize current supply time to an auxiliary coil of the compressor. CONSTITUTION:When a compressor is started, a starting switch 3 is closed by output of a controlling microcomputer 6 and a starting switch driving circuit 7. Next, a connecting and disconnecting switch 2 is closed by the output of the microcomputer 6 and a connecting and disconnecting switch driving circuit 8. An electric current is flowed to a main coil 1a and an auxiliary coil 1b by commercial electric power supply voltage, and after the connecting and disconnecting switch 2 is closed, the starting switch 3 is opened beforehand at the minimum thinkable starting time, and when starting failure is caused in this condition, a signal of a starting detector 4 is outputted, and the connecting and disconnecting switch 2 is opened. Next, time obtained by adding a second to the previous minimum starting time is set. The starting switch 3 and the connecting and disconnecting switch 2 are closed again, and the starting switch 3 is opened at newly set time. When the compressor is started normally in this condition, starting time at this time is stored in the microcomputer 6, and thereafter the compressor is started at this time.
