Description

Technical Field

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

[0002] Rotary compressors work by using a high-speed rotating motor to drive an eccentric shaft to compress refrigerant within a cylinder, achieving cooling and heating functions through heat conversion of the refrigerant. The high-speed rotation of the compressor motor generates pulses, and the mechanical friction of the pump body inevitably leads to noise in the compressor. Furthermore, compressors operate at various frequencies, including their natural frequencies. The natural frequency of the compressor casing falls around 1.5kHz, and the upper part of the casing vibrates significantly. Since human hearing is most sensitive around 1.5kHz, existing compressor casings cannot effectively reduce noise in the 1.5kHz frequency range, resulting in a poor user experience. Utility Model Content

[0003] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a compressor housing and a compressor having the same. The spliced ​​design can improve the rigidity of the upper cylinder, and by setting reinforcing ribs on the inner wall of the upper cylinder, the rigidity of the upper cylinder can be further strengthened, reducing resonance response and thus reducing noise.

[0004] To achieve the above objectives, a first aspect of this utility model provides a compressor housing, including a main cylinder, an upper cylinder, and an end cap. The main cylinder is a cylindrical structure open at one end, and the interior of the main cylinder is suitable for installing a compressor motor and pump body structure. The upper cylinder is a cylindrical structure open at both ends, with one end of the upper cylinder sealed to the open end of the main cylinder. The end cap is provided at the end of the upper cylinder away from the main cylinder. The inner wall of the upper cylinder is provided with reinforcing ribs, the width of which is d, and the thickness of the upper cylinder is T, satisfying the relationship: 0.2T≤d≤5T.

[0005] Furthermore, the thickness of the reinforcing rib is t, which satisfies the relationship: 0.2T≤t≤5T.

[0006] Therefore, according to the embodiment of the present utility model, the compressor housing adopts a splicing design to assemble the main cylinder, upper cylinder and end cover together, which can improve the rigidity and strength of the upper cylinder. The addition of reinforcing ribs on the inner wall of the upper cylinder can greatly increase the rigidity and strength of the upper cylinder, thereby reducing the resonance amplitude of the upper cylinder, reducing noise, and ensuring that the natural frequency of the compressor housing no longer falls near 1.5kHz, effectively improving the user experience.

[0007] In one embodiment, a number of reinforcing ribs are evenly and spaced apart on the inner wall of the upper cylinder, and the distance between two adjacent reinforcing ribs is H, satisfying the relationship: 10mm≤H≤100mm.

[0008] In one embodiment, the reinforcing rib is a circular reinforcing ring, and the axis of the reinforcing ring overlaps with the axis of the upper cylinder.

[0009] In one embodiment, the reinforcing rib is inclinedly disposed on the inner wall of the upper cylinder, and the inclination angle of the reinforcing rib is β, satisfying the relationship: 15°≤β≤85°.

[0010] In one embodiment, the reinforcing rib is an X-shaped cross structure.

[0011] In one embodiment, the reinforcing rib has a curved outline.

[0012] In one embodiment, the outer peripheral wall of one end of the upper cylinder is sealed to the inner peripheral wall of the open end of the main cylinder, and the end cap sealing cover is provided on the outer peripheral wall of the end of the upper cylinder away from the main cylinder.

[0013] A second aspect of this utility model provides a compressor comprising the compressor housing described in any of the preceding embodiments. The compressor according to this utility model employs a spliced ​​design to improve the rigidity of the upper cylinder, and by providing reinforcing ribs on the inner wall of the upper cylinder, the rigidity of the upper cylinder can be further strengthened, reducing resonance response and thus lowering noise.

It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance.

[0026] In related technologies, rotary compressors work by using a high-speed rotating motor to drive an eccentric shaft to compress refrigerant within a cylinder, achieving cooling and heating functions through heat conversion of the refrigerant. The high-speed rotation of the compressor motor generates pulses, and the mechanical friction of the pump body inevitably leads to noise in the compressor. Furthermore, compressors operate with excitation and natural frequencies across various frequency bands, particularly the compressor casing, whose natural frequency falls around 1.5kHz. The upper part of the compressor casing also vibrates significantly. Since human hearing is most sensitive around 1.5kHz, existing compressor casings cannot effectively reduce noise in the 1.5kHz frequency band, resulting in a poor user experience.

[0027] In view of this, the present invention provides a compressor housing and a compressor having the same. According to the present invention, the compressor housing and compressor having the same feature employ a spliced ​​design to improve the rigidity of the upper cylinder 20, and by providing reinforcing ribs 21 on the inner wall of the upper cylinder 20, the rigidity of the upper cylinder 20 can be further strengthened, reducing resonance response and thus reducing noise.

[0028] Please see Figures 1 to 6 The first aspect of this utility model provides a compressor housing, including a main cylinder 10, an upper cylinder 20, and an end cap 30. The main cylinder 10 is a cylindrical structure with one open end, and the interior of the main cylinder 10 is suitable for installing the compressor motor and pump body structure. The upper cylinder 20 is a cylindrical structure with both open ends, and one end of the upper cylinder 20 is sealed to the open end of the main cylinder 10. The end cap 30 is provided at the end of the upper cylinder 20 away from the main cylinder 10. A reinforcing rib 21 is provided on the inner wall of the upper cylinder 20. The width of the reinforcing rib 21 is d, and the thickness of the upper cylinder 20 is T, satisfying the relationship: 0.2T≤d≤5T. In addition, the thickness of the reinforcing rib 21 is t, satisfying the relationship: 0.2T≤t≤5T.

[0029] Therefore, according to the embodiment of the present utility model, the compressor housing adopts a splicing design to assemble the main cylinder 10, the upper cylinder 20, and the end cover 30 together, which can improve the rigidity and strength of the upper cylinder 20. Furthermore, the addition of reinforcing ribs 21 on the inner wall of the upper cylinder 20 can greatly increase the rigidity and strength of the upper cylinder 20, thereby reducing the resonance amplitude of the upper cylinder 20, reducing noise, and ensuring that the natural frequency of the compressor housing no longer falls near 1.5kHz, effectively improving the user experience.

[0030] The main cylinder 10, upper cylinder 20, and end cap 30 can be assembled using processes such as welding. For example, in this embodiment, the outer peripheral wall of one end of the upper cylinder 20 is sealed to the inner peripheral wall of the open end of the main cylinder 10. The end cap 30 is sealed to the outer peripheral wall of the end of the upper cylinder 20 furthest from the main cylinder 10. Welding the outer peripheral wall of the upper cylinder 20 to the open edge of the end cap 30 fixes the end cap 30 to the upper cylinder 20, and welding the outer peripheral wall of the upper cylinder 20 to the open edge of the main cylinder 10 fixes the upper cylinder 20 to the main cylinder 10. It is worth noting that in some other embodiments, the inner peripheral wall of the upper cylinder 20 can also be sealed to the outer peripheral wall of the open end of the main cylinder 10, which will not be elaborated upon here.

It can be understood that in these embodiments, the number of reinforcing ribs 21 can be set according to actual needs, and the rigidity of the upper cylinder 20 can be further improved by limiting the distance between two adjacent reinforcing ribs 21.

[0032] Optionally, in some embodiments of this utility model, the reinforcing rib 21 is a circular reinforcing ring, and the axis of the reinforcing ring overlaps with the axis of the upper cylinder 20. It can be understood that in these embodiments, the reinforcing rib 21 is designed as a circular structure, which can further improve the rigidity of the upper cylinder 20.

[0033] Optionally, in some embodiments of this utility model, the reinforcing rib 21 is inclinedly disposed on the inner wall of the upper cylinder 20, and the inclination angle of the reinforcing rib 21 is β, satisfying the relationship: 15°≤β≤85°. It can be understood that in these embodiments, the reinforcing rib 21 is inclinedly disposed, which can further improve the rigidity of the upper cylinder 20.

[0034] Optionally, in some embodiments of this utility model, the reinforcing rib 21 is an X-shaped intersecting structure. It can be understood that in these embodiments, the reinforcing rib 21 is designed as an X-shaped intersecting structure, which can further improve the rigidity of the upper cylinder 20.

[0035] Optionally, in some embodiments of this utility model, the outline shape of the reinforcing rib 21 is curved. It can be understood that in these embodiments, the reinforcing rib 21 is arranged in a curved shape, which can further improve the rigidity of the upper cylinder 20.
