Abstract
A simple inverter-controlled refrigerator includes temperature detector (), constant speed main body control unit () whose power is turned on/off by temperature detector (), and that can drive a constant speed compressor, inverter control unit () that is connected to constant speed main body control unit (), and that is operated, based on a power on/off signal of constant speed main body control unit (). And variable speed compressor () that is connected to inverter control unit (), and that is controlled, based on an output from inverter control unit (). Inverter control unit () has rotation speed setting unit () which is operated, based on the power on/off signal of constant speed main body control unit (), and which is configured to set a rotation speed of variable speed compressor (), and inverter drive circuit unit () which drives variable speed compressor () at the rotation speed set by rotation speed setting unit ().
