Refrigerator with function of evaporative defrosting water

Technical field

The utility model relates to a refrigerator, in particular to a refrigerator with the function of defrosting water, more specifically, to a refrigerator with the function of evaporating and defrosting water.

Background technique

Existing refrigerators are usually provided with a plurality of compartments, and a refrigeration system is provided in the refrigerator, and the refrigeration system usually includes a compressor, an evaporator and a condenser connected by refrigerant pipelines. During the refrigeration process of the refrigerator, the moisture in the air tends to form frost on the low-temperature evaporator. If the frosted evaporator does not remove the frost layer in time, it will affect the heat conduction and reduce the refrigeration effect of the refrigerator. Therefore, the refrigerator is usually equipped with The defrosting device is to defrost the evaporator and compartment of the refrigerator after the refrigerator has been used for a certain period of time. The frost layer is usually removed by heating, and the defrosting water formed by melting the frost layer after heating is usually passed through the defrosting system connected to the refrigerator compartment. The water pipe discharges the refrigerator, because directly removing the defrosting water is easy to pollute the surrounding environment, some inventors have invented a method of directly heating and evaporating the defrosting water to directly evaporate the defrosting water into the surrounding environment, as disclosed in Chinese patent 98116723 A refrigerator defrosting water evaporating device has multiple bottom walls to separate the lower space from the refrigerating chamber, a chassis installed under the refrigerator, and a partition that forms an integral part with the chassis to divide the lower space into first and second spaces , a drain pipe that introduces the defrosting water into the first space, a fixed part of the condenser, so that the defrosting water is in direct contact with the condenser, and evaporates the defrosting water through heat exchange with the condenser, and the fixed part has a pair of condensers fixed In the part and extension part, the defrosting water evaporation function is completed through the chassis, and the isolation space in the lower part of the refrigerator occupies a small volume. The defrosting water is in direct contact with the condenser to increase the evaporation efficiency of the defrosting water. Although the technical solution disclosed in the above patent document can directly evaporate the defrosting water through the heat of the condenser, the arrangement of the water receiving tray on the condenser is complicated, the production process is cumbersome, and it is prone to failure. Another kind of refrigerator with the function of directly evaporating and defrosting water is as the Chinese patent 94221082. This patent document discloses a water receiver for a refrigerator with both radiation and evaporation heat dissipation functions. The water head and the fixed foot frame make the inner wall of the annular groove close to the compressor of the refrigerator, which increases the radiation heat dissipation area of the compressor, and the frosted water flowing into the annular groove through the water head will be evaporated in time, and the vaporization It can greatly accelerate the heat dissipation of the compressor. It can not only hold the frosted water discharged from the refrigerator, but also have certain functions of saving electricity and protecting the refrigerator compressor. The technical solution disclosed in the above patent documents solves the problem of evaporating defrosting water to a certain extent, but due to the structural problems of the compressor, it is difficult to install the water receiving tray closely with the compressor, which may cause the defrosting water to evaporate untimely, and at the same time Once the water pan leaks, it will have a bad effect on the compressor.
