Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a freezing cabinet with a deodorizing function. Background Art

[0002] The basic function of a freezer is to refrigerate and keep the inside of the box at a suitable low temperature. The refrigeration system is generally composed of four basic components: a compressor, a condenser, a capillary tube or a thermal expansion valve, and an evaporator. Refrigerant is a liquid that can boil at low temperature under low pressure and absorb heat when boiling. The refrigerant circulates continuously in the refrigeration system. The compressor increases the gas pressure of the refrigerant to create liquefaction conditions. When passing through the condenser, it condenses and liquefies to release heat, and then reduces the pressure and temperature when passing through the capillary tube. When passing through the evaporator, it boils and vaporizes to absorb heat. In addition, the development and use of refrigeration diodes nowadays do not have complex mechanical devices, but the performance is poor. It is used in small refrigerators. Some existing freezers store food that will emit some odors after spoiling. Even if the spoiled food is cleaned up later, the odor is still difficult to eliminate, and there may be certain health hazards. Utility Model Content

[0005] A further technical solution is that a dryer is installed in the return air duct, and the dryer is located on the side of the activated carbon close to the negative pressure fan.

[0006] A further technical solution is that a compressor unit is installed at the bottom of the freezer body, and the return air duct is in contact with a heat exchange plate on the top of the compressor unit.

[0007] A further technical solution is that filters are installed in both the air outlet and the air inlet.

[0008] A further technical solution is that a storage plate is installed in the freezer body, and the storage plate is slidably connected to a slide groove on the inner wall of the freezer body.

[0009] The utility model has the following advantages: the utility model arranges a negative pressure fan to circulate the air in the freezer through the air outlet and the air inlet, and the activated carbon arranged in the return air duct can remove odors and filter the circulating air, effectively eliminating the odor of the freezer, improving the user experience, and ensuring the hygiene of the air inside the freezer; by arranging a dryer, a certain dehumidification effect can be achieved, thus preventing water vapor from damaging the activated carbon, ensuring the service life of the activated carbon, and reducing the accumulation of water vapor in the freezer to breed bacteria.
