Embodiment Construction

[0033] The invention provides a defrosting method and a defrosting device for an evaporator of a refrigerator, which uses a refrigeration device to defrost the evaporator.

[0034] The defrosting method is the same as the existing method of using the high-pressure and high-temperature refrigerant coming out of the compressor to directly enter the evaporator without going through the condenser to heat and defrost the evaporator. In order to solve the problem that the water cannot be drained due to the blockage of the drain pipe opening of the water pan by the frost formed, the present invention proposes that the high-pressure high-temperature refrigerant should be connected to the water pan and drained from the water pan before entering the evaporator. The tube is heated to melt the ice, the drainage channel is opened, and then the evaporator is defrosted.

[0035] The first method of heating the drain pipe of the water tray to melt the ice is to arrange the hot defrosting pipe...

Abstract

The invention relates to a defrosting method of an evaporator of a freezer, taking use of high pressure high temperature refrigerant from a compressor which directly enters the evaporator without going through a condenser to heat up and defrost the evaporator and being characterized in that: the high pressure high temperature refrigerant firstly heats up and deices a water pan and drainpipes of the water pan before entering the evaporator. The invention ensures that a hot defrosting pipe enters through the drainpipes at the bottom part of the water pan to firstly melt the ice in the drainpipes at the bottom part of the water pan with the heat of the hot defrosting pipe, then enters into the evaporator to defrost, so as to open a channel before defrosting and to put an end to the blockage problem of the drainpipes at the bottom part of the water pan.

Description

technical field [0001] The invention relates to a refrigerating device, in particular to a refrigerator evaporator defrosting device which utilizes the refrigerating device to defrost the evaporator. Background technique [0002] A general freezer or refrigerator compresses the refrigerant (refrigerant) into a high-temperature and high-pressure gaseous refrigerant, condenses it into a liquid low-temperature refrigerant through a capillary tube, enters an evaporator through a capillary tube, evaporates, expands and absorbs heat to become a gaseous refrigerant, and then enters a compressor to compress into a high-temperature and high-pressure refrigerant. The circulation of gaseous refrigerant reduces the temperature inside the box and maintains the freshness of food within a certain period of time. The liquid refrigerant evaporates in the evaporator and absorbs a large amount of heat to lower the temperature of the evaporator, and exchanges heat with the surrounding environme...
