As a result, the energy-saving effect is reduced
[0032] On the other hand, when the set value of the cooler temperature for stopping the internal blower is set at a temperature higher than 0°C, when the amount of frost is relatively large, the time at which 0°C is constant as described above (latent heat change part) becomes longer, during this period, the temperature of the freezer compartment in the state of cutting off the cold air circulation rises significantly, and even if the user does not make any special mistakes, sometimes there is a possibility that the frozen food will melt

The invention provides a refrigerator with high energy saving performance, and the problem that temperature of foodstuff in the refrigerator can not be maintained in a prescribed temperature scope is not easy to occur for the refrigerator. The refrigerator comprises a first defrosting mechanism, a second defrosting mechanism, and a third defrosting mechanism, in the first defrosting mechanism, when a compressor is stopped, a freezing chamber air door is closed, a refrigerating chamber air door is opened, a defrosting heater is in non-power-up state, and a blower works for defrosting; in the second defrosting mechanism, when the compressor is stopped, the refrigerating chamber air door is closed, the refrigerating chamber air door is opened, the defrosting heater is in power-up state, and the blower works for defrosting; in a third defrosting mechanism, when the compressor is stopped, the refrigerating chamber air door is closed, the refrigerating chamber air door is closed, the defrosting heater is powered up, and the blower is in stopping state for defrosting. The refrigerator has a plurality of defrosting modes which use one or more of the first defrosting mechanism, the second defrosting mechanism and the third defrosting mechanism to carry out defrosting operation, after one of the plurality of defrosting modes is selected to carry out defrosting operation, the defrosting heater is in power-up state, and the blower is in stopping state for defrosting.
Description
technical field [0001] The present invention relates to a refrigerator, and more particularly to a refrigerator that automatically performs a defrosting operation for removing frost adhering to a cooler. Background technique [0002] In the refrigerator of the cold air forced circulation method that uses a shared cooler to cool the refrigerating chamber (corresponding to the refrigerating temperature zone chamber of the present invention) and the freezing chamber (corresponding to the freezing temperature zone chamber of the present invention), as the defrosting As some techniques, techniques of Patent Document 1 to Patent Document 4 shown below are known. [0003] Patent Document 1 describes a technique for defrosting by turning on a defrosting heater in a stopped state of a compressor, a closed state of a full damper, and a stopped state of an interior blower. [0004] Patent Document 2 describes a technique in which the damper of the refrigerating room is opened when the...
