ABSTRACT:
A refrigerator capable of controlling a fan motor, in which the fan motor rpm is controlled according to a cooling load, are disclosed. The refrigerator comprises a DC fan motor for operating a cooling fan; a controller for determining cooling load according to inner temperature of the refigerator sensed by thermal sensor and for generating a control signal to select an AC voltage according to the detemined cooling load; a transformer for decreasing an input voltage by several AC voltage levels; a switch for selecting a voltage level output from the transformer according to the control signal from the controller; and a rectifier for converting AC voltage to DC voltage and for supplying the DC voltage to the DC fan motor. According to the above, the rpm of the cooling fan can be varied and controlled easily depending on cooling load of the refrigerator using a DC fan motor.
