Description

Defrosting plate for refrigerator

Technical Field

The utility model belongs to the technical field of the refrigerator defrosting board, especially, relate to a defrosting board for refrigerator.

Background

The structure schematic diagram of the existing direct-cooling two-door refrigerator is shown in fig. 1, and the refrigerator comprises a refrigerating chamber 1 and a lower freezing chamber, wherein the refrigerating chamber 1 is provided with an evaporator 2 and a lining 3, and the evaporator is attached to the inner surface of the lining 3 and is positioned in a foaming layer of the refrigerator. Because the cold energy of the evaporator 2 is transmitted into the refrigerating compartment 1 to cool the food, the heat transfer mode of the evaporator mainly depends on natural convection. The refrigeration phase tends to accumulate a frost layer on the outer surface of the liner 3 covered by the evaporator 2, which can only be defrosted by natural rewarming during the refrigeration system shutdown phase. This process, due to the complexity of the use of the user of the refrigerator, often causes the formation of frost on the outer surface of the liner 3 covered by the evaporator 2, locally or over the whole surface thereof, requiring manual removal by interruption of the power supply.

As shown in fig. 2, the refrigerant of the refrigeration system sequentially passes through the compressor, the anti-condensation pipe, the condenser, the filter, the capillary tube, the refrigeration evaporator and then returns to the compressor to form a complete refrigeration cycle. The whole refrigerator is refrigerated, and the compressor is controlled to be started and stopped by the sensor in the refrigerating chamber, so that the heat transfer characteristic of the evaporator of the refrigerating chamber determines the performance of the whole refrigerator. Because the evaporator 2 is directly attached to the lining 3, a user frequently opens and closes the door, the compressor is started for a long time when the load is too large, or excessive food is put in to affect cold quantity transmission and the like, the condition is easy to be condensed into frost on the back of the lining 3, and the heat transfer performance of the evaporator 2 is affected. Because there is no automatic defrosting component, the user is required to power off or manually remove the frosted back, and the user experience is poor.

In order to solve the problem, the utility model provides a defrosting board for refrigerator.
