Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a compressor housing and a compressor. Background Technology

[0002] As the core component of a refrigerator system, the compressor's internal pump mechanism is mounted in the lower compressor housing via four vibration-damping springs. The upper and lower housings are assembled by welding. The compressor housing primarily serves a sealing and fixing function. The vibration and noise generated by the pump during operation are insulated by the housing before being transmitted. Therefore, the shape and thickness of the housing affect the compressor's noise level. Furthermore, the excitation force generated by the compressor pump during operation is a wide-frequency excitation, and the housing's natural frequency is easily excited by this wide-frequency excitation, generating noise and vibration. The housing's natural frequency is mainly determined by its shape. In conclusion, improving the NVH (noise, vibration, and stiffness) level of a reciprocating compressor housing requires optimized design of the housing's shape.

[0003] Vibration and noise are key indicators for consumers when evaluating the quality of household refrigerators. To reduce overall vibration and noise, household refrigerators generally use fully enclosed reciprocating compressors. The noise of these compressors primarily originates from sound radiation emanating from the casing. Currently, methods to improve compressor casing noise include increasing casing thickness, enlarging chamfers to avoid abrupt changes in curvature, using asymmetrical designs, and adding damping structures. However, as compressor costs are controlled, the thickness of the compressor casing is gradually decreasing, which leads to increased noise levels. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The following is for reference. Figures 1-9 The following describes the compressor housing 100 of an embodiment of the present utility model.

[0026] like Figures 1 to 4 As shown, the compressor housing 100 of this embodiment includes an upper housing 10 and a lower housing 20. The upper housing 10 includes a first upper wall segment 11 and a second upper wall segment 12. The first upper wall segment 11 is circumferentially arranged around the second upper wall segment 12, and the second upper wall segment 12 protrudes upward relative to the first upper wall segment 11, so that a first reinforcing rib 13 is formed between the second upper wall segment 12 and the first upper wall segment 11. The lower housing 20 is connected to the upper housing 10. The lower housing 20 includes a first lower wall segment 21 and a second lower wall segment 22. The first lower wall segment 21 is circumferentially arranged around the second lower wall segment 22, and the second lower wall segment 22 protrudes downward relative to the first lower wall segment 21, so that a second reinforcing rib 23 is formed between the second lower wall segment 22 and the first lower wall segment 21.

[0027] The upper housing 10 can refer to the upper half-shell of the compressor housing 100. The upper housing 10 can consist of at least two parts: a first upper wall section 11 and a second upper wall section 12. The first upper wall section 11 is circumferentially arranged around the second upper wall section 12, and the second upper wall section 12 is located in the inner region of the entire upper housing 10. Therefore, the shape of the second upper wall section 12 can be, but is not limited to, a circle, a square, a "⊥" shape, or an irregular shape, etc. Since the second upper wall section 12 protrudes upward relative to the first upper wall section 11, a first reinforcing rib 13 can be formed in the connection area between the second upper wall section 12 and the first upper wall section 11. The shape of the first reinforcing rib 13 is similar to the outer edge contour of the second upper wall section 12.

[0028] The lower housing 20 can refer to the lower half-shell of the compressor housing 100. The lower housing 20 includes a first lower wall section 21 and a second lower wall section 22. The first lower wall section 21 surrounds the second lower wall section 22. The shape of the second upper wall section 12 can be, but is not limited to, circular, square, U-shaped, and irregular shapes. Since the second lower wall section 22 protrudes downward relative to the first lower wall section 21, a second reinforcing rib 23 can be formed in the connection area between the second lower wall section 22 and the first lower wall section 21. The shape of the second reinforcing rib 23 is similar to the outer edge contour of the second upper wall section 12.

[0029] In the above technical solution, since a complete annular first reinforcing rib 13 can be formed on the upper housing 10, the complete annular first reinforcing rib 13 can form a larger reinforcing area on the upper housing 10, thus significantly improving the structural strength of the upper housing 10. Similarly, since a complete annular second reinforcing rib 23 can be formed on the lower housing 20, the complete annular second reinforcing rib 23 can also form a larger reinforcing area on the lower housing 20, thus significantly improving the structural strength of the lower housing 20. This solution helps to reduce the thickness of the upper housing 10 and the lower housing 20 as much as possible, thereby increasing the chamfers of the upper housing 10 and the lower housing 20 while ensuring structural strength. For example, the upper surface of the upper housing 10 can be made as flat as possible, thus reducing noise and vibration problems caused by the compressor housing 100.

[0030] According to the embodiment of the present utility model, the compressor housing 100 is provided with a first reinforcing rib 13 in the upper housing 10 and a second reinforcing rib 23 in the lower housing 20. This can achieve lightweight housing while ensuring structural strength, thereby reducing the radiated noise generated by the resonance of the compressor housing 100. This can reduce the noise and vibration of the compressor and improve the user experience of the compressor.

[0031] In some embodiments of this utility model, reference is made to Figures 2 to 4 The compressor housing 100 has a first direction and a second direction that are perpendicular to each other, and the size of the compressor housing 100 in the first direction is larger than the size in the second direction; the second upper wall section 12 includes a first wall portion 121 and a second wall portion 122, the first wall portion 121 extends along the arcuate surface of the upper housing 10 in the first direction, and the second wall portion 122 is disposed at one end of the first wall portion 121 in the first direction and extends along the arcuate surface of the upper housing 10 in the second direction.

[0032] For example, refer to Figures 2 to 4 The first direction can be left and right, and the second direction can be front and back. It can be understood that the first wall portion 121 and the second wall portion 122 can be arc-shaped walls and perpendicular to each other. The second upper wall segment 12 formed by the first wall portion 121 and the second wall portion 122 can be, but is not limited to, T-shaped, L-shaped, etc.

[0033] In the above technical solution, by configuring the first wall portion 121 and the second wall portion 122 as described above, the distribution area of ​​the second upper wall segment 12 on the upper housing 10 is smoother and has a larger area, thereby allowing the size of the annular structure formed by the first reinforcing rib 13 to be larger. The first wall portion 121 enables the first reinforcing rib 13 to have a strength-enhancing effect in the first direction of the upper housing 10, reducing the thickness of the upper housing 10 in the first direction. The second wall portion 122 enables the first reinforcing rib 13 to have a strengthening effect in the second direction of the upper housing 10, reducing the thickness of the upper housing 10 in the second direction, which can bring a stronger strengthening effect, thereby enhancing the overall structural strength of the upper housing 10. This is beneficial for making the upper housing 10 thinner, and thus helps to reduce the noise and vibration of the compressor housing 100.

[0034] In some embodiments of this utility model, reference is made to Figures 2 to 4 The first wall portion 121 and the second wall portion 122 are connected at the middle position in the second direction. In the above technical solution, the first wall portion 121 and the second wall portion 122 can form a T-shaped structure. This structure has a larger size and area, and can radiate in multiple directions to achieve strength enhancement in multiple directions, further improving the structural strength of the upper shell 10.

[0035] In some embodiments of this utility model, reference is made to Figures 2 to 4 The arc length of the first wall portion 121 in the first direction is less than the arc length of the second wall portion 122 in the second direction.

[0036] Since the compressor housing 100 has a larger dimension in the first direction than in the second direction, and based on the shape of the compressor housing 100, the dimensions of the first wall portion 121 in the first and second directions are not significantly different, and the dimensions of the second wall portion 122 in the first and second directions are also not significantly different. As a result, both the first wall portion 121 and the second wall portion 122 are short and wide, and the reinforcing ribs at the locations of the first wall portion 121 and the second wall portion 122 have higher strength, thus providing a better strength enhancement effect for the upper housing 10.

[0037] In some embodiments of this utility model, reference is made to Figures 1 to 4 The upper housing 10 is provided with a pump body limiting part 14. The first wall part 121 is provided with the pump body limiting part 14 adjacent to both sides in the first direction, and the second wall part 122 is provided with the pump body limiting part 14 adjacent to the other side in the second direction away from the first wall part 121.

[0038] The pump body limiting part 14 is a structure that limits the compressor pump body 200 inside the compressor housing 100. For example, the pump body limiting part 14 can be a limiting protrusion that is recessed downward from the upper housing 10. In the above embodiment, multiple pump body limiting parts 14 are provided, and the shapes and structures of the multiple pump body limiting parts 14 can be the same or different.

[0039] In the above technical solution, by setting the first wall portion 121 and the second wall portion 122 and the pump body limiting portion 14 in the above structure, the distribution of the first wall portion 121, the second wall portion 122 and the pump body limiting portion 14 is more compact, which is conducive to increasing the distribution range of the first wall portion 121 and the second wall portion 122 on the upper shell 10, thereby increasing the size and strength reinforcement range of the first reinforcing rib 13, and thus improving the structural strength of the upper shell 10.

[0040] In some embodiments of this utility model, the connection between the first wall portion 121 and the second wall portion 122 is a rounded transition, and the corners of the first wall portion 121 and / or the second wall portion 122 are provided with rounded corners and chamfers. The use of these rounded corners, chamfers, and chamfers can avoid the risk of stress concentration on the first wall portion 121 and the second wall portion 122, thereby improving the reliability of the first reinforcing rib 13.

[0041] In some embodiments of this utility model, reference is made to Figure 2 , Figure 5 and Figure 6 The compressor housing 100 has a first direction and a second direction that are perpendicular to each other, and the size of the compressor housing 100 in the first direction is larger than the size in the second direction; the second lower wall section 22 includes a third wall portion 221 and a fourth wall portion 222. The third wall portion 221 is centrally arranged on the lower housing 20, and the fourth wall portion 222 is provided at both ends of the third wall portion 221 in the second direction. The size of the third wall portion 221 in the first direction is larger than the size of the fourth wall portion 222 in the second direction.

[0042] For example, refer to Figure 2 , Figure 5 and Figure 6 The first direction is left and right, and the second direction is front and back.

[0043] In the above technical solution, by configuring the third wall portion 221 and the fourth wall portion 222 into the aforementioned structure, the second reinforcing rib 23 can strengthen the lower housing 20 at its middle position and in the first direction, and also strengthen the lower housing 20 at both ends in the second direction. This improves the overall structural strength of the lower housing 20, thereby reducing noise and vibration. Furthermore, the above solution allows the shape of the second lower wall section 22 to be adapted to the lower housing 20, and consequently, the shape of the second reinforcing rib 23 to be adapted to the lower housing 20. This effectively disperses stress concentration issues experienced by the compressor housing 100 during operation, further reducing the possibility of resonance and lowering the radiated noise generated by resonance in the compressor housing 100.

[0044] In some embodiments of this utility model, reference is made to Figure 2 , Figure 5 and Figure 6 In the second direction, the width of the third wall portion 221 gradually decreases from the middle to both sides, while the width of the fourth wall portion 222 remains unchanged.

[0045] In the above technical solution, the width of the third wall portion 221 gradually decreases from the middle to both sides, which can better adapt to the overall structure of the lower housing 20, while optimizing the stress distribution, reducing the risk of structural failure caused by stress concentration, and improving the structural strength of the lower housing 20. The width of the fourth wall portion 222 remains unchanged to ensure the stability of the structure of the lower housing 20, further improve the structural strength of the lower housing 20, enhance the vibration resistance of the lower housing 20, and reduce the radiated noise generated by the resonance of the compressor housing 100.

[0046] In some embodiments of this utility model, reference is made to Figure 2 , Figure 5 and Figure 6 The fourth wall portion 222 extends upward to near the outer edge of the lower housing 20. In the above technical solution, the fourth wall portion 222 extends upward to near the outer edge of the lower housing 20, thereby increasing the size of the second lower wall section 22, and consequently increasing the size of the second reinforcing rib 23. This enhances the structural strength of the two side edges of the lower housing 20 in the second direction, thereby improving the effect of the second reinforcing rib 23 on the structural strength of the lower housing 20, and further improving the reliability of the lower housing 20.

[0047] In some embodiments of this utility model, reference is made to Figure 5 and Figure 6 The lower housing 20 is provided with a foot mounting portion 24 and a seat spring mounting portion 25. The foot mounting portions 24 are provided adjacent to both sides of the third wall portion 221 in the second direction, and the seat spring mounting portions 25 are provided adjacent to both sides of the fourth wall portion 222 in the second direction.

[0048] refer to Figures 5 to 7When assembling the compressor housing 100, four positioning pins are welded to the seat spring mounting portion 25 of the lower housing 20. Resin bushings are mounted on the positioning pins, and these bushings mate with the seat spring 400 inside the compressor 1000. The compressor pump body 200 is mounted on the seat spring 400, and the foot mounting portion 24 can be connected to an external mechanism via mounting feet 300. The seat spring 400 is used for vibration damping.

[0049] The foot mounting portion 24 and the seat spring mounting portion 25 are usually located on the outermost periphery of the lower housing 20. By adopting the above technical solution, the arrangement of the third wall portion 221 and the foot mounting portion 24 is more compact, which is conducive to increasing the area ratio of the third wall portion 221 on the lower housing 20. The distribution of the fourth wall portion 222 and the seat spring mounting portion 25 is also more compact, which is conducive to increasing the area ratio of the fourth wall portion 222 on the lower housing 20. This can increase the size of the second reinforcing rib 23, thereby improving the structural strength of the lower housing 20 and reducing the noise and vibration of the lower housing 20.

[0050] In some embodiments of this utility model, the connection between the third wall portion 221 and the fourth wall portion 222 is a rounded transition, and the corners of the third wall portion 221 and / or the fourth wall portion 222 are provided with rounded corners and chamfers. The use of these rounded corners, chamfers, and chamfers can avoid the risk of stress concentration on the third wall portion 221 and the fourth wall portion 222, thereby improving the reliability of the second reinforcing rib 23.

[0051] like Figure 7 As shown, a compressor 1000 is also provided according to an embodiment of the present utility model, including the compressor housing 100 of any of the preceding embodiments.

[0052] The compressor 1000 can be, but is not limited to, a reciprocating compressor, a positive displacement compressor, and a power compressor, etc. For example, the compressor 1000 can be a reciprocating compressor. It should be noted that the compressor 1000 described above can be applied to refrigerators, air conditioners, vehicles, ships, and aviation, etc. For example, the compressor housing 100 can be used in refrigerators. Other components and operations of the compressor 1000, such as the pump, compression mechanism, lubrication system, shock absorption and support system, are known to those skilled in the art and will not be described further here.

[0053] According to the present invention, the compressor 1000 has a relatively thin and strong housing, and therefore has low noise and vibration. Thus, using the compressor housing 100 can effectively reduce the noise and vibration of the compressor 1000.

[0054] The following is combined with Figures 1 to 9 This describes a specific embodiment of the compressor housing 100 of the present invention.

The first upper wall segment 11 is circumferentially arranged around the second upper wall segment 12, and the second upper wall segment 12 protrudes upward relative to the first upper wall segment 11, so that a first reinforcing rib 13 is formed between the second upper wall segment 12 and the first upper wall segment 11. The second upper wall segment 12 includes a first wall portion 121 and a second wall portion 122. The first wall portion 121 extends along the arcuate surface of the upper shell 10 in a first direction, and the second wall portion 122 is located at one end of the first wall portion 121 in the first direction and extends along the arcuate surface of the upper shell 10 in a second direction.

The first wall part 121 is provided with pump body limiting parts 14 on both sides in the first direction, and the second wall part 122 is provided with pump body limiting parts 14 on the other side in the second direction away from the first wall part 121.
