Claims

[Scope of utility model registration request]

A freezer compartment cooler consists of an auxiliary cooler for placing food and cooling it, and a main cooler for cooling circulating air by a fan; a refrigerator compartment cooler; a compressor; A first control valve that supplies both the cooler and the cooler for the refrigerator compartment, and a second control valve that supplies the auxiliary and main coolers for the freezer compartment, and normally drives and stops the compressor depending on the freezer compartment temperature. refrigeration room temperature detection means for controlling the temperature and closing both control valves to a refrigerant flow path cutoff state when the compressor is stopped, and supplying refrigerant from the supply to the refrigerator compartment cooler and the freezer compartment main cooler. refrigeration room temperature detection means for switching the opening/closing state of the surface control valve in order to switch the supply to the auxiliary freezer compartment cooler and the main cooler; If the state in which the refrigerator compartment is supplied with water continues for a predetermined time or longer, the first control valve is closed and the second control valve is opened regardless of the refrigerating room temperature detection means, and the state in which the inside temperature of the refrigerating compartment is equal to or higher than the predetermined temperature is determined. 2. A refrigerator according to claim 1, wherein when the time continues, the compressor is operated and the first control valve is opened regardless of the freezing room temperature detection means.
