Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a liquid receiver assembly structure and a compressor including the liquid receiver assembly structure. Background Technology

[0002] The compressor housing contains a cylinder, and the cylinder's air inlet is connected to the liquid receiver's outlet pipe. After the refrigerant absorbs heat and vaporizes in the evaporator, it undergoes gas-liquid separation in the liquid receiver, and then the low-temperature, low-pressure refrigerant gas is sent into the cylinder for compression through the liquid receiver's outlet pipe.

[0003] In the prior art, the compressor receiver assembly structure is as follows: Figure 1 As shown, the cylinder wall of cylinder 01 is provided with an air inlet hole 010, and the housing 02 is provided with a through hole 020 at a position corresponding to the air inlet hole 010. One end of the housing seat ring 03 is connected to the through hole 020 of the housing 02. One end of the air inlet connecting pipe 04 is inserted into the housing seat ring 03, and the other end of the air inlet connecting pipe 04 extends into the air inlet hole 010 of cylinder 01. The outlet pipe 05 of the liquid reservoir is inserted into the inner side of the air inlet connecting pipe 04. To achieve a seal, the air inlet connecting pipe 04 and the air inlet hole 010 of cylinder 01 are interference-fitted, and the two are rigidly connected. This connection method can lead to minor leaks under high pressure, affecting the overall performance of the compressor. Furthermore, the force required to press the inlet pipe 04 into the inlet port 010 of the cylinder 01 is significant, potentially causing cylinder 01 deformation and displacement, thus impacting compressor quality. Additionally, the rigid connection between the cylinder 01 and the inlet pipe 04 means that noise and vibration generated during cylinder 01 operation are directly transmitted to the receiver, increasing compressor noise. Moreover, to ensure compressor airtightness, the housing ring 03 and the through hole 020 of the housing 02 are sealed by pressure welding, while the housing ring 03, inlet pipe 04, and outlet pipe 05 are sealed by brazing. This process involves numerous components, requires multiple welding operations, is complex, and incurs high processing costs. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is to provide a liquid reservoir assembly structure that can reduce leakage, reduce noise, reduce assembly parts, and ensure sealing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a liquid reservoir assembly structure, including an air inlet on a cylinder, a through hole on the housing that houses the cylinder at a position corresponding to the air inlet, an air outlet pipe of the liquid reservoir, and a sealing ring. The outlet end of the air outlet pipe is inserted into the air inlet through the through hole. The air outlet pipe is welded to the housing. The sealing ring is located between the outlet end of the air outlet pipe and the air inlet. The distance between the location of the sealing ring and the welding position of the air outlet pipe and the housing is not less than 20mm.

[0007] Preferably, the air inlet has an annular groove on its wall, and the sealing ring is fitted onto the outer circumferential surface of the air outlet and embedded in the annular groove.

[0008] Preferably, the air outlet pipe and the air inlet are fitted with a clearance.

[0009] Preferably, the sealing ring is made of ethylene propylene rubber, hydrogenated nitrile rubber, or fluororubber.

[0010] Preferably, the sealing ring and the vent pipe are independent separate parts or integrally formed parts.

[0011] Preferably, a limiting portion protruding outward is formed on the outer peripheral surface of the vent pipe near the outlet end of the vent pipe, and the limiting portion abuts against the outer side of the housing and is welded to the housing.

[0012] Preferably, the vent pipe is connected to the housing by high-frequency welding or laser welding.

[0013] This utility model also provides a compressor, including the liquid receiver assembly structure described above.

[0014] Compared with the prior art, this utility model has significant progress:

[0015] The liquid reservoir assembly structure of this utility model allows the liquid reservoir's outlet pipe to be directly inserted into the cylinder's inlet hole through a through hole in the housing, and then welded to the housing. This eliminates the need for a housing seat ring and an inlet connecting pipe, reducing assembly workpieces, welding components, and welding times, simplifying the assembly process and reducing processing and material costs. A sealing ring between the outlet pipe and the inlet hole reduces leakage, improves compressor performance, and lowers compressor noise. It also avoids cylinder deformation and displacement caused by the large pressure of the interference fit seal, improving compressor quality. In particular, the liquid reservoir assembly structure of this utility model designs the sealing ring to be located at least 20mm away from the welding point between the outlet pipe and the housing, creating a safe distance that reduces the impact of welding temperature on the sealing ring, preventing it from melting due to welding temperature and ensuring that the sealing ring's performance is not affected by the welding of the outlet pipe and the housing.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0038] like Figure 2 The image shows one embodiment of the liquid reservoir assembly structure provided by this utility model.

[0039] The liquid reservoir assembly structure of this embodiment includes an air inlet 10 on the cylinder 1, a through hole 20 on the housing 2, an outlet pipe 3 of the liquid reservoir, and a sealing ring 4. The cylinder 1 is housed inside the housing 2, and the through hole 20 is located on the housing 2 at a position corresponding to the air inlet 10. The end of the outlet pipe 3 away from the liquid reservoir is the outlet end, and the outlet end of the outlet pipe 3 is inserted into the air inlet 10 through the through hole 20 to deliver low-temperature, low-pressure refrigerant gas into the cylinder 1 for compression. The outlet pipe 3 is welded to the housing 2 to ensure airtightness. The sealing ring 4 is located between the outlet end of the outlet pipe 3 and the air inlet 10 to achieve a seal between the outlet pipe 3 and the air inlet 10. The location of the sealing ring 4 is at least 20mm away from the welded position of the outlet pipe 3 and the housing 2. Figure 2 As shown, the distance between the welding position of the vent pipe 3 and the housing 2 and the position of the sealing ring 4 is H, where H ≥ 20 mm.

[0040] In this embodiment, the liquid reservoir assembly structure allows the liquid reservoir's outlet pipe 3 to be directly inserted into the air inlet 10 of the cylinder 1 through the through hole 20 on the housing 2, and the outlet pipe 3 to the housing 2 to be welded. This eliminates the need for the housing seat ring and the air inlet connecting pipe, reducing the number of assembly parts, welding components, and welding times, thus simplifying the assembly process and reducing processing and material costs. The outlet pipe 3 and the air inlet 10 are sealed by a sealing ring 4, which reduces leakage, improves compressor performance, and reduces compressor noise. It also avoids cylinder 1 deformation and displacement caused by the large pressure of the interference fit seal, thus improving compressor quality. In particular, the liquid reservoir assembly structure of this embodiment designs the sealing ring 4 to be located at a distance of not less than 20mm from the welding position of the outlet pipe 3 and the housing 2, thereby forming a safe distance. This reduces the impact of welding temperature on the sealing ring 4 during welding, prevents the sealing ring 4 from melting due to welding temperature, and ensures that the performance of the sealing ring 4 is not affected by the welding of the outlet pipe 3 and the housing 2.

[0041] In this embodiment, preferably, the air inlet 10 has an annular groove 11 on its wall, the sealing ring 4 is sleeved on the outer circumferential surface of the air outlet 3 and embedded in the annular groove 11, the sealing ring 4 is interference-fitted with the annular groove 11, and the inner ring of the sealing ring 4 abuts against the outer circumferential surface of the air outlet 3, thereby forming a seal between the air outlet 3 and the air inlet 10.

[0042] In this embodiment, preferably, the exhaust pipe 3 and the air inlet 10 are fitted with a clearance fit, with the clearance size preferably being 0.2mm ± 0.05mm. This clearance fit facilitates easy and smooth insertion of the exhaust pipe 3 into the air inlet 10, simplifying assembly. Since the exhaust pipe 3 and the air inlet 10 are sealed by the sealing ring 4, the clearance fit between them does not affect the sealing performance.

[0043] In this embodiment, preferably, the material of the sealing ring 4 is ethylene propylene rubber (EPDM), hydrogenated nitrile butadiene rubber (HNBR), or fluororubber (FKM).

[0044] In this embodiment, the sealing ring 4 and the vent pipe 3 can be independent separate parts, or the sealing ring 4 and the vent pipe 3 can be integrally formed, preferably by vulcanization integral molding.

[0045] In this embodiment, preferably, a limiting part 31 protruding outward is formed on the outer peripheral surface of the vent pipe 3 near the outlet end of the vent pipe 3. The limiting part 31 abuts against the outer side of the housing 2 and is welded to the housing 2. The vent pipe 3 is fixed to the housing 2 by welding through the limiting part 31 abutting against the outer side of the housing 2, which facilitates the welding operation and ensures the welding sealing effect.

[0046] In this embodiment, preferably, the air outlet pipe 3 and the housing 2 are connected by high-frequency welding or laser welding.

[0047] Based on the liquid receiver assembly structure of this utility model, this utility model embodiment also provides a compressor. The compressor of this embodiment includes the liquid receiver assembly structure described above.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
