Description

Technical Field

[0001] The utility model belongs to the technical field of compressors and relates to a compressor support component, a compressor and a refrigeration device. Background Art

[0002] At present, the normal speed range of refrigerator compressors is 1200-4500rpm. In order to meet the demand for lower energy consumption, the speed of the compressor needs to be further reduced. However, when the compressor runs at a low speed, the operating frequency is close to the natural frequency of the compressor movement, which can easily cause the amplitude of the movement to increase sharply, causing the movement to shake, thereby driving other parts to vibrate and increase noise. In the prior art, the compressor usually uses four compression springs with sufficient rigidity and elasticity to provide support. Research and experiments have shown that by increasing the inner diameter of the compression spring and improving the lateral support stability, the amplitude of the movement at low speed can be greatly reduced, and the vibration and noise of the compressor can be greatly reduced. However, the existing structure has certain limitations, that is, due to the space limitation between the compression spring and the motor frame, the inner diameter of the compression spring cannot be increased, and the lateral support stability cannot be improved. If the size of the compressor motor is increased and a structural design that avoids the motor frame is adopted, although the inner diameter of the compression spring can be increased, it will lead to higher product costs.

[0031] like Figures 1 to 4 As shown, the compressor support assembly of this embodiment includes a support bracket 1, a compressor movement 2, a movement assembly, a compression spring 3 and a compression spring assembly.

[0032] The support bracket 1 is provided with a plurality of first mounting portions 11 on the inner side in the radial direction, and the support bracket 1 is provided with a plurality of second mounting portions 12 on the outer side in the radial direction.

[0033] The first assembly portion 11 is located within the positive projection of the compressor movement 2 or on the side of the compressor movement 2 . The first assembly portion 11 is assembled and connected to the compressor movement 2 via a movement assembly part.

[0034] Specifically, the first assembly part 11 defines a first assembly hole 111. In this embodiment, a first assembly part 11 is arranged at each of the four corners of the support bracket 1, and each first assembly part 11 defines a first assembly hole 111. A second assembly hole is defined on the compressor movement 2, and the movement assembly part is configured as a screw 4, which assembles and connects the first assembly hole 111 and the second assembly hole.

[0035] The second assembly portion 12 is at least partially located outside the orthographic projection of the compressor core 2, the compression spring 3 is located at the lower end surface of the second assembly portion 12, the second assembly portion 12 is assembled and connected to the upper end of the compression spring 3 through the compression spring assembly part, and the compression spring 3 is arranged along the vertical extension. Among them, the second assembly portion 12 is located outside the orthographic projection of the compressor core 2, so that the second assembly portion 12 is arranged radially outward, increasing the space between the compression spring 3 and the compressor core 2 (including the motor frame 21).

[0036] The second assembly part 12 is provided with a third assembly hole 121, and the compression spring assembly part includes a compression spring support sleeve 51 and a bolt 52. The bolt 52 is assembled and connected with the compression spring support sleeve 51 and the third assembly hole 121, and the upper end of the compression spring 3 is matched with the compression spring support sleeve 51. The screw of the bolt 52 is sequentially passed through the through hole on the upper part of the compression spring support sleeve 51 and the third assembly hole 121 on the second assembly part 12, and the upper end of the screw of the bolt 52 is exposed from the upper end surface of the second assembly part 12, and a nut is assembled on the upper end of the screw of the bolt 52. The compression spring support sleeve 51 is made of plastic, and during the operation of the compressor, the friction noise between the compression spring support sleeve 51 and the compression spring 3 is reduced.

[0037] In this embodiment, a second assembly portion 12 is arranged at each of the four corners of the support bracket 1, and each second assembly portion 12 has two third assembly holes 121. In this way, according to different types of compressors, any number of the third assembly holes 121 can be selected to assemble the compression spring support sleeve 51 to achieve flexible arrangement of the compression spring 3. It is also possible to assemble the compression spring support sleeve 51 in each third assembly hole 121 to increase the number of compression springs 3 to achieve multi-compression spring 3 support, improve the lateral support stiffness, and improve the lateral support stability.

[0038] The support bracket 1 is set as a flat plate structure, and the plane of the support bracket 1 fits the lower end surface of the compressor core 2. In this way, the height of the compressor core 2 is basically not increased, so that the compressor core 2 can adapt to the original shell size. In addition, the support bracket 1 is set as a flat plate structure, which can be formed by a stamping process, with low production cost and high production efficiency.

[0039] A compressor, specifically a variable frequency compressor, comprises a shell, and also comprises the compressor support assembly mentioned above in this embodiment, wherein the compressor support assembly is located inside the shell, and the lower end of the compression spring 3 contacts the shell.

[0040] A refrigeration device includes the compressor described above in this embodiment, wherein the refrigeration device includes but is not limited to a refrigerator, a freezer, an air conditioner, etc.
