The present invention relates to a rapid deicing device of a refrigerator, and more particularly, to a rapid deicing device of a refrigerator to cool water contained in the ice making container within a short time to reduce power consumption and improve the efficiency of the evaporator. will be.

In general, a refrigerator sends a low-temperature and low-pressure liquid refrigerant to a compressor, compresses it with a high-temperature, high-pressure gas refrigerant, sends the compressed refrigerant to a condenser to liquefy, and then sends the refrigerant reduced by a capillary tube to an evaporator. One refrigeration cycle is repeatedly executed to cool the inside of the refrigerator to a set temperature. As shown in FIG. 1, the refrigerator main body 10 is partitioned into a freezing and refrigerating chamber 10a and 10b as shown in FIG. On the front of the) is a freezing and refrigerating chamber doors (12, 14) for sealing the interior of the freezing and refrigerating chamber (10a) (10b) is coupled to open and close.

An ice maker 20 is accommodated in the freezer compartment 10a as shown in FIG. 2, and the ice maker 20 has a receiving part 24 recessed to a predetermined depth with a separating wall 22 to hold water therein. On the inner wall surface of the freezer compartment 10a, a shelf 16 is mounted to support the ice making container 20 at a predetermined height from the bottom surface. In the refrigerating chamber 10b, a plurality of shelves (not shown) are mounted in multiple layers so as to place refrigeration objects such as food.

On the rear wall side of the freezer compartment 10a, a cover 26 having a plurality of discharge ports 26a is mounted, and a duct 28 serving as an air flow path is fixed to a rear side thereof, and a compressor (not shown) is provided on one side of the duct 28. And a blower fan 32 are installed to forcibly blow air into the freezer compartment 10a and the evaporator 30 for cooling the surrounding air while evaporating the gas refrigerant.

In the conventional refrigerator configured as described above, when the compressor is started to store the object stored in the freezing and refrigerating chambers 10a and 10b at a set temperature for a long time, the evaporator 30 takes away the latent heat of evaporation to cool the surrounding air, As the blower fan 32 rotates at a high speed, air is discharged into the freezing and refrigerating chambers 10a and 10b to maintain the freshness of the object.

In the ice making container 20 supported by the shelf 16, air cooled from the evaporator 30 is discharged through the discharge port 26a of the cover 26 to the receiving portion 24 of the ice making container 20. Converts water into ice At this time, when the water is rapidly defrosted (within a short time), the discharge amount of the air discharged into the freezer compartment 10a is increased to make ice or to rapidly defrost by lowering the temperature in the refrigerator.

However, as the water contained in the ice making container in the freezing chamber having a limited volume as described above gradually changes to ice from the discharge port of the duct, it takes a long time (about 180 minutes) to make ice as a whole.

In addition, as the discharge amount is excessively increased to rapidly cool the ice making container, moisture around the evaporator freezes, causing frost on the surface of the evaporator, which lowers the cooling efficiency. There was a problem.

The present invention is to solve the above problems, an object of the present invention is to provide a defrosting container with a heat pipe bound on its back, at the same time to change the water contained in the ice making container into ice as well as the ice making time of the ice making container The present invention provides a rapid deicing device for a refrigerator which can shorten (about 35 minutes), in particular, improve the cooling efficiency of the evaporator, and reduce the power consumption to a minimum.
