Description
Technical Field
[0001] This utility model belongs to the field of refrigerator accessories technology, specifically relating to an integrated refrigerator return pipe assembly. Background Technology
[0002] As an indispensable appliance in modern homes and businesses, the performance of a refrigerator's refrigeration system directly affects its usability and energy consumption. The return pipe, a key component of the refrigerator's refrigeration system, plays a crucial role in transporting the low-temperature, low-pressure refrigerant gas from the evaporator back to the compressor.
[0003] In a refrigerator's refrigeration system, the return gas pipe is closely connected to components such as the evaporator and compressor, forming a closed refrigeration cycle. The refrigerant absorbs heat in the evaporator, becoming a low-temperature, low-pressure gas, and then flows back to the compressor through the return gas pipe. The compressor compresses the gas and delivers it to the condenser to release heat. Therefore, the heat exchange efficiency of the return gas pipe directly affects the refrigerant's circulation speed and cooling effect. Traditional return gas pipes have a drawback: if the return gas pipe is damaged, the refrigerator can only function normally after a professional repairman has completed all repairs. During the period before repair, the refrigerator must be powered off and stop working. Therefore, during this time, food inside the refrigerator will spoil, shortening its shelf life and reducing the user experience. Utility Model Content

[0037] Furthermore, after the second connecting ring 33 is connected to the return air pipe 51, a second sealing ring 34 is provided inside the second connecting ring 33 to increase the sealing between the second connecting ring 33 and the return air pipe 51. When the first connecting ring 23 is connected to the return air pipe 51, a first sealing ring 24 is provided inside the first connecting ring 23 to increase the sealing between the first connecting ring 23 and the return air pipe 51. When the return air pipe 51 is fixed between the first connecting ring 23 and the second connecting ring 33, the sealing between the return air pipe 51 and the first connecting ring 23 and the second connecting ring 33 is increased through the cooperation of the first sealing ring 24 and the second sealing ring 34.
[0038] Furthermore, in this utility model, in order to support the air inlet component 2 and the air outlet component 3, such as... Figures 1-3 As shown, the component also includes a support member 1 for supporting the air intake 2 and the air outlet 3. Two first fixing brackets 15 and two second fixing brackets 16 are fixedly connected to one side of the support member 1.
