Description

Technical Field

[0001] The utility model relates to the technical field of liquid reservoirs, in particular to a liquid reservoir processed without solder. Background Art

[0002] The liquid receiver is an important component of the compressor, which plays the role of storage, gas-liquid separation, filtering, silencing and refrigerant buffering. The existing liquid receivers are mainly divided into three types: one-piece spin-type liquid receiver, two-stage liquid receiver and three-stage liquid receiver.

[0003] During actual use, it was found that under the condition of equal axial length, compared with the two-stage liquid reservoir and the three-stage liquid reservoir, the existing one-piece spinning liquid reservoir is affected by the "neck" structure produced by the spinning process, resulting in a smaller liquid storage volume at the outlet end and a lower liquid storage capacity. At the same time, due to the small volume, when working with the compressor, the coolant that is still in liquid state can easily enter the compressor, causing the compressor to have a "liquid hammer" problem. At the same time, due to the small volume, the internally stored coolant and the internal structure are prone to vibration, resulting in poor silencing effect.

[0004] In addition, the straight air inlet pipe and the bent air outlet pipe used in the existing spin-type liquid storage device are mostly plain tubes with smooth outer walls. There are problems such as great difficulty in positioning and difficulty in maintaining good concentricity with the cylinder during processing and assembly. In addition, additional solder is required during the welding process, resulting in low production efficiency, high energy consumption and high production cost.

[0005] This shows that the prior art still has certain defects. Utility Model Content

However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0038] Continue to refer to Figure 1 and Figure 6 As shown, the area of ​​the figure enclosed by the radial plane at the connection point of the arc portion 113 and the straight pipe section 13, the arc portion 113, the flat portion 112 and the projection of the pipe wall of the outlet elbow 21 on the axial section is S1, and the area of ​​the image enclosed by the radial plane at the connection point of the conical portion 122 and the straight pipe section 13, the radial plane at the connection point of the conical portion 122 and the neck portion 123, and the projection of the extension line of the pipe wall of the outlet elbow 21 on the axial section is S2; S1 is 1.7-2.2 times of S2.

[0039] By adopting the above structure, the flattened portion 112 and the arc-shaped portion 113 are arranged so that the shaped air outlet end 11 in the present application presents a rounded flat bottom profile as a whole, and the neck 123 structure of the air outlet end of the traditional spun liquid reservoir is eliminated, so that the radial and axial dimensions of the liquid storage space at the bottom of the shaped air outlet end 11 are increased, so that the liquid storage volume of the shaped air outlet end 11 in the present application is effectively increased compared with the liquid storage volume of the air outlet end of the traditional spun liquid reservoir, which is also conducive to reducing the impact of the small volume on the mute effect, improving the mute performance of the liquid reservoir during use, and bringing users a better use experience. At the same time, the spun air inlet end 12 and the shaped air outlet end 11 in the above scheme are simple in structure and easy to process, which is conducive to improving production efficiency and saving production costs while improving product performance.

The adoption of this structure, combined with the limiting cooperation between the aforementioned second limiting step 232 and the air outlet mounting hole 111, is conducive to ensuring that the straight pipe portion of the air outlet bend 21 inserted into the cylinder 1 has a high concentricity with the cylinder 1; at the same time, the air outlet bend 21 and the middle partition 4 and the filter 3 have a radial limiting effect on each other, reducing the radial movement of the middle partition 4, the filter 3 and the air outlet bend 21 during use, ensuring the stability of the installation of the middle partition 4 and the filter 3, and also playing a role in shock absorption and noise reduction.

[0043] Further, refer to Figure 5As shown, along the radial direction of the straight pipe section 13, the straight pipe section 13 is provided with a first limiting protrusion 131 and a second limiting protrusion 132 protruding toward the inside of the straight pipe section 13; along the axial direction of the straight pipe section 13, the first limiting protrusion 131 is arranged on both sides of the filter screen 3, and the second limiting protrusion 132 is arranged on both sides of the middle partition plate 4.
