Description

Cabinet door defrosting mechanism and refrigerator

Technical Field

The utility model relates to an electric refrigerator-freezer design and manufacturing technical field especially relate to a cabinet door defrosting mechanism and refrigerator-freezer thereof.

Background

At present, refrigerators produced, sold and used are of a direct cooling type and an indirect cooling type, wherein the indirect cooling type refrigerator is also called a frost-free refrigerator, and the frost-free refrigerator is just that frost layers are formed on the surface of an evaporator, so people can not see the frost layers in the refrigerator. Direct-cooling refrigerators have more pronounced frosting than indirect-cooling refrigerators, and are mostly in the freezer compartment. During the operation of the refrigerator, the frost layer may hinder the heat exchange of the evaporator surface, thereby affecting the refrigerating efficiency of the refrigerator. The thicker the frost layer is, the poorer the refrigerating efficiency is, and thus, it is an important way to improve the performance of the refrigerator to defrost the refrigerator regularly. There are two common defrosting methods: the first method is the traditional manual defrosting or natural defrosting method: firstly, turning off the power supply of the refrigerator, and transferring all articles in the refrigerator; then, the refrigerator door is opened to perform natural or artificial defrosting. In the case of manual or natural defrosting, people often use hot water or the like to promote the melting of the frost layer.

The prior art has the following problems:

application No.: CN201620108528.5 discloses a defrosting device for a refrigerator, which comprises a box, a liquid storage tank, a condensing heat exchange coil, a defrosting heat exchange coil, an evaporating coil and a circulating pump, wherein the defrosting heat exchange coil and the evaporating coil are arranged in a freezing chamber of the box side by side, the liquid storage tank is arranged above the defrosting heat exchange coil, and the condensing heat exchange coil is arranged in the liquid storage tank; a water supply pipeline is arranged between the liquid storage tank and the defrosting heat exchange coil, and a valve for controlling liquid to flow downwards is arranged on the water supply pipeline; a liquid collecting tank for collecting liquid flowing downwards from the defrosting heat exchange coil is arranged below the defrosting heat exchange coil; one side of the liquid collecting tank is provided with a circulating pump and a circulating pipeline, and the circulating pump and the circulating pipeline can send the liquid collected by the liquid collecting tank back to the liquid storage tank to form circulation of liquid medium heat. The problem that the defrosting method is not ideal is solved, and firstly, the whole defrosting process consumes longer time; secondly, the melted water needs to be removed continuously, and the water flow is troublesome once careless; thirdly, the delay time of the refrigerated food outside the refrigerator is too long, which is not beneficial to the preservation and fresh-keeping of the food.

However, when manual or natural defrosting is adopted, the efficiency is low, time and labor are wasted, and the preservation and the fresh keeping of food are not facilitated.
