REFRIGERATOR AND CIRCULATING FAN CONTROL METHOD

摘要

PURPOSE: A refrigerator and a control method of a circulating fan are provided to reduce the number of defrosting with a defrosting heater by defrosting naturally with the circulating fan and to save power by restricting increase of temperature in the refrigerator with the defrosting heater. CONSTITUTION: An evaporator is installed to a refrigerating room side to cool a refrigerating room. A circulating fan circulates air of the refrigerating room and a rotating motor rotates the circulating fan. A temperature sensor(401) senses temperature of the refrigerating room. A defrosting temperature sensor(403) senses temperature of the evaporator. A micro computer(400) operates a defrosting operation by controlling the rotating motor after comparing temperature of the temperature sensor with the defrosting temperature sensor when the refrigeration room is not cool. Thereby, defrosting time of the evaporator and power are reduced.
