ABSTRACT:
An air curtain generator generates an air curtain in a refrigerant compartment of a refrigerator. In the air curtain generator, a sensor senses open and closed states of a refrigerant compartment door. A brushless direct current air curtain fan blows cool air into a refrigerant compartment according to a sensing result of the sensor in order to generate an air curtain in the refrigerant compartment. A direct current power source supplies a direct current driving current to the brushless direct current air curtain fan. A driver drives the brushless direct current air curtain fan. A microcomputer controls an operation of the driver according to the sensing result of the sensor. The air curtain generator maximizes functions of an air curtain generator by applying a brushless direct current air curtain fan having low noise level, low power consumption, and high efficiency thereto. The air curtain generator also controls a rotating speed of a brushless direct current air curtain fan according to a state of the refrigerant compartment to thereby adjust air speed.
