The refrigerating components arranged in the assembly space are communicated to form a refrigerating circulation system, the refrigerating circulation system is utilized to realize the refrigerating process of the refrigerator, and the refrigerating system comprises a compressor, a condenser, an evaporator and other refrigerating components.

When the refrigerator works, the compressor compresses the refrigerant into high-pressure gas, the high-pressure gas flows into the condenser, the high-pressure gas is cooled into liquid through the condenser and releases energy, the liquid refrigerant can enter the evaporator through the throttling device, and the refrigerant in the evaporator can absorb the energy in the refrigerator, so that the temperature in the refrigerator is reduced.

When the refrigerator is used, due to the fact that the door is frequently opened and closed or the door seal arranged between the door body 2 and the refrigerator body 1 is not tight, damp and hot water vapor in the external environment can enter the refrigerator, frosting is easy to occur on the inner wall of the liner of the refrigerator, heat exchange between the evaporator and the air in the refrigerator can be increased when frosting is too thick, heat exchange on the surface of the evaporator is prevented, and therefore refrigerating efficiency is reduced, and refrigerating efficiency is affected.

Therefore, the refrigerator needs to be defrosted in time in the working process, and the defrosting of the refrigerator can be automatically performed by arranging the defrosting module 3.

Simultaneously set up and subtract frost module 3, because of the setting that subtracts frost hole 74 is with the inside air intercommunication of cabinet body 1 with cabinet body 1, can balance the inside of freezer and the atmospheric pressure of outside air for can not consume too big strength just can be relaxed opening the door body when opening the door body 2 of freezer, promote user's use experience.

When the compressor is operated, air outside the cabinet 1 flows into the cabinet 1 through the defrosting holes 74, the second defrosting pipes 7, the first defrosting pipes 6, the air duct box 5, the connecting pipes 51, the mounting boxes 41, the mounting ports and the air vents in sequence.

Under the action of the air pressure difference between the external space and the cabinet body 1, air in the external space enters the storage chamber through the frost reducing module 3, the air pressure in the storage chamber gradually rises along with the air entering of the external space, and finally the air pressure in the external space and the air pressure in the storage chamber tend to be balanced, so that the frosting amount in the cabinet body 1 can be reduced.

The specific process of reducing the frosting quantity in the cabinet body 1 through the frosting reducing module 3 is as follows:

after the compressor starts to operate, air in the storage chamber in the refrigerator is cooled and contracted, the air pressure in the storage chamber is reduced, and after the air pressure in the storage chamber is gradually reduced to be smaller than the air pressure in the external space, the air with smaller air pressure in the external space of the cabinet body 1 enters the defrosting module 3 from the defrosting hole 74 and sequentially enters the storage chamber from the air vent along the defrosting pipe, the connecting pipe and the mounting box 41, and is mixed with the air with larger air pressure in the storage chamber, so that the air pressure difference between the air pressure in the storage chamber and the external space is reduced, and the frosting amount in the cabinet body 1 is reduced.

Compared with the connection mode of the first defrosting pipe 6 and the second defrosting pipe 7 in the prior art, the clamping part 73 for connecting the second defrosting pipe 7 and the first defrosting pipe 6 improves the installation efficiency of the defrosting module 3 and improves the appearance quality of the door body 2 after foaming of the foaming structure by optimizing the connection structure of the defrosting module 3.

In summary, the clamping part is arranged between the first defrosting pipe and the second defrosting pipe in the defrosting module in the refrigerator, the first defrosting pipe and the second defrosting pipe can be firmly fixed on the door body through the specific clamping part, the mounting hole is formed in the side wall of the door body, the assembly part is arranged in the first defrosting pipe, the clamping part is arranged at one end, close to the first defrosting pipe, of the second defrosting pipe, and the clamping part penetrates through the mounting hole and is clamped on the assembly part so as to fixedly connect the first defrosting pipe and the second defrosting pipe, meanwhile, the first defrosting pipe and the second defrosting pipe are fixed on the door body, the end part of the second defrosting pipe is prevented from tilting, the appearance quality is improved, the fixing of a sponge and an adhesive tape is saved, and the cost is saved.
