Description

Technical Field

[0001] The utility model relates to the technical field of defrosting devices, in particular to a defrosting device for a cold storage door. Background Art

[0002] The prior art has the following problems:

[0003] A cold storage is a facility used to store and preserve food, medicines, and other perishable items. Usually, cold storage can achieve refrigeration in the following ways:

[0004] Refrigerant circulation system: Cold storage usually uses a refrigerant circulation system for refrigeration. The system includes components such as a compressor, condenser, expansion valve, and evaporator. The refrigerant circulates in the system, and the refrigeration effect is achieved by changing the pressure and temperature of the refrigerant.

[0005] Compressor: The compressor is the core component of the cold storage refrigeration system, which is used to increase the pressure and temperature of the refrigerant. When the refrigerant is compressed, its temperature will also rise.

[0006] Condenser: The condenser is a heat sink that dissipates the heat given off by the refrigerant into the air or water. As the refrigerant passes through the condenser, its temperature drops.

[0007] Expansion valve: The expansion valve is used to control the flow of refrigerant into the evaporator and reduce the pressure of the refrigerant.

[0008] Evaporator: The evaporator is the main refrigeration equipment in the cold storage, which is used to absorb the heat from the air in the cold storage. When the refrigerant evaporates in the evaporator, it absorbs heat from the environment, thereby reducing the temperature inside the cold storage.

[0009] 1. When the cold storage is refrigerating, the cold storage door will freeze, making it difficult to open and close the cold storage door. At this time, you need to turn off the refrigeration of the cold storage and open the cold storage, or forcefully open the cold storage door. Either way will cause property losses.

[0010] 2. The existing defrosting devices of cold storage doors are mostly low-voltage heating wires arranged on the outer ring of the door leaf, which are powered on to generate heat for defrosting. When a circuit failure occurs in the cold storage door during use, the heating wire is prone to melting, and defrosting cannot be performed, and the melted water cannot be recycled, causing the melted water to fall directly on the ground and freeze, which has a certain impact on entering and exiting the cold storage.
