<P>PROBLEM TO BE SOLVED: To provide a controller that can control rotating speed of a compressor according to load. <P>SOLUTION: When a DC motor 107 is in operation, operating time of a timer 121 is set according to an input current detected by an input current detector 122 to increase the rotating speed of the DC motor 107 after the lapse of the set time, thereby controlling the rotating speed of a compressor according to a load. Accordingly, the compressor performs high-speed rotation operation when the load on a refrigerator is determined to be large, and performs low-speed rotation and energy-saving operation when the load is determined to be small. <P>COPYRIGHT: (C)2013,JPO&INPIT |
