Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises a shell, a storage liner positioned in the shell and a door body; the shell is provided with two side plates positioned on two sides of a first direction; the storage liner defines a storage compartment and a taking and placing opening positioned in a second direction that is different from the first direction; the door body is arranged at the taking and placing opening so as to open or close the storage compartment; a convex part which extends to the direction of the door body and to the inner side of the first direction is formed on one side, facing the door body, of each side plate; and the end edge, facing the door body, of each convex part is closer to the door body than the end edge, facing the door body, of the side of the storage liner in the first direction so that the gap between one side, facing the door body, of each side plate of the shell and the door body is reduced, the air convection intensity of the gapis reduced, and the problems of door sealing and heat leakage of the door body are reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration and freezing storage, in particular to a refrigerator. Background technique [0002] In recent years, the energy efficiency standards of refrigerators in major countries and regions around the world have been continuously upgraded, and the administrative regulations of various countries have become more and more stringent, which has guided refrigerator manufacturers to increase investment in energy-saving research. [0003] The energy consumption of the refrigerator is mainly determined by two aspects, namely, the heat load of the whole machine (caused to maintain the temperature difference between the interior of the room and the external environment) and the cycle efficiency of the refrigeration system (related to the compressor, evaporation pressure, condensation pressure, etc.). The heat load of the whole machine mainly includes the heat leakage through the foam layer (including the heat...

AI Technical Summary

Problems solved by technology

[0004] Generally speaking, the heat load of the door seal accounts for 20-25% of the heat load of the whole machine. In existing refrigerators, the gap between the front face of the U shell and the door body is relatively large, and the air convection in the gap is relatively strong. Once the door seal is sealed Bad, will produce a relatively strong heat leakage

In addition, there is generally a dew removal tube at the joint between the front face of the U shell and the inner tank to prevent condensation on the door seal. The increase in temperature has the effect of removing dew, but in the existing refrigerator, the contact area between the dew removal pipe and the front face of the U shell is small, and the heat transfer effect is poor
