Description

Refrigerating equipment

Technical Field

The utility model relates to a refrigeration plant field especially relates to domestic refrigeration plant such as refrigerator, freezer to and the rack that wherein uses.

Background

With the development of science and technology and the increasing improvement of the living standard of people, household refrigeration equipment such as refrigerators, refrigerated cabinets and the like are increasingly widely applied. At the same time, consumer demands for the performance of domestic refrigeration equipment are increasing. The refrigerators or freezers currently available on the market include both air-cooled and direct-cooled types.

The principle of the air-cooled refrigerator is that air is utilized to refrigerate, when high-temperature air flows through an evaporator which is arranged in the refrigerator and is separated from the inner wall of the refrigerator, the air temperature is reduced because the air temperature is high and the evaporator temperature is low, the air temperature and the evaporator temperature directly exchange heat, and cold air is blown into the refrigerator to reduce the temperature of the refrigerator. The frost of the air-cooled refrigerator is condensed on the evaporator, and the frost can not be directly seen when a consumer opens the refrigerator door, so the air-cooled refrigerator is very popular with the consumer in the market in recent years. However, there is a problem in that the air-cooled refrigerator needs to stop cooling, start a heating system, and defrost an evaporator after operating for a certain period of time.

The principle of the direct-cooling refrigerator is that an evaporator is used for refrigerating, and the evaporator is arranged in a freezing chamber and is in direct contact with the inner wall of the freezing chamber for heat exchange. The evaporators are composed of refrigerating coils, and the refrigerant output by the compressor flows through the pipelines, so that the temperature of the pipelines is low, and the temperature of the inner wall of the refrigerator is indirectly reduced through the pipelines, so that the temperature of the refrigerator is reduced. Direct-cooling refrigerators are still popular with many consumers in the market due to their mature technology and economical and practical properties. However, the direct-cooling refrigerator has the problems that although the direct-cooling refrigerator can continuously work and does not need to pause refrigeration, the phenomenon that cold air sinks and gathers exists in the direct-cooling refrigerator, so that the upper and lower temperature difference in the refrigeration equipment is large, the refrigeration effect is not uniform, the frosting phenomenon is easy to occur on the lower portion of the direct-cooling refrigerator except refrigeration unevenness, food storage is not facilitated, the storage space is occupied, and the user experience is influenced.

Chinese patent application publication No. CN1888795A discloses a refrigerator shelf.
