Refrigerating and freezing device

Abstract

The invention relates to a refrigerating and freezing device comprising a box body and a door body located on the front side of the box body. A mechanical chamber is formed in the lower portion of the rear side of the box body, and a compressor used for compressing refrigerants and a condenser used for conducting heat exchange with air are contained in the mechanical chamber; the mechanical chamber is provided with an air inlet and an air outlet for allowing air flows to circulate between the mechanical chamber and the external environment; the door body is internally provided with a door body air exhaust channel; the door body air exhaust channel indirectly communicates with the air outlet of the mechanical chamber or an air outlet area adjacent to the air outlet so as to lead at least part of hot air flows generated in the mechanical chamber into the door body air exhaust channel; heat in the part of the hot air flows can be fully used for increasing the temperature of the door body, therefore, the heat in the mechanical chamber is fully utilized, and accordingly, the door body can be further effectively prevented from generating condensation. Meanwhile, only by specifically designing the door body air exhaust channel inside the door body, a series of difficult problems in the prior art can be solved, the refrigerating and freezing device is simple in structure and easy to achieve.

Description

technical field [0001] The invention relates to refrigeration and freezing storage technology, in particular to a refrigeration and freezing device. Background technique [0002] When the existing refrigerator is in cooling operation, part of the cold energy will be transferred to the door body of the refrigerator. Although there is a door sealing device on the door body for sealing, it is inevitable that part of the cold energy will escape through the contact between the door body and the box body. When the door body uses a built-in handle, the foam layer at the built-in handle is thinner than other parts, and part of the cold energy will also be transferred to the handle. Because the air in the environment has a certain humidity, when the temperature of the hidden handle in the door is lower than the dew point temperature, condensation will appear. When the overflowing cold energy between the door body and the cabinet makes the temperature lower than the dew point temper...

AI Technical Summary

Problems solved by technology

The method of using the dew removal pipe has a more complicated structure, and the process of placing the dew removal pipe needs to be increased; the method of increasing the thickness of the foam layer will reduce the available volume of the compartment, making the door thick and difficult to open, increasing the cost; increasing the way of the heating device will lead to increased power consumption
