Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a compressor assembly and an air conditioner. Background Art

[0002] Conventional rolling rotor compressors are mainly composed of a compressor body and a liquid reservoir. The compressor body is mainly composed of a pump body assembly, a motor assembly, and a casing, while the liquid reservoir is mainly composed of an air inlet pipe, a filter, a straight pipe, a cylinder, a partition, and an air outlet elbow. The liquid reservoir is arranged on one side of the compressor body and is fixed to the liquid reservoir bracket on the shell of the compressor body through a liquid reservoir pressure plate. Its air inlet pipe is connected to the system pipeline, and the air outlet elbow is connected to the pump body suction hole of the compressor body. The high-temperature and high-pressure refrigerant gas generated by the compressor pump body assembly enters the system pipeline from the compressor outlet. After being converted into a low-temperature and low-pressure gas through condensation and evaporation in the system pipeline, it enters the liquid reservoir through the liquid reservoir air inlet pipe. After being filtered by the liquid reservoir filter, it flows through the liquid reservoir straight pipe and the air outlet elbow and enters the compressor pump body, realizing the periodic circulation working process of the compressor and the system pipeline.

[0003] Since the liquid reservoir of the above-mentioned conventional rotor compressor is installed on one side of the compressor body, the swing vibration generated by the rotation of the rotating parts of the compressor is one of the main sources of vibration of the liquid reservoir. The swing vibration of the liquid reservoir cylinder can be effectively improved by fixing the liquid reservoir bracket. However, the lower part of the liquid reservoir, especially the exhaust elbow, is in a free swinging state and is the connection part with the compressor pump body cavity, so its radial vibration relative to the shell is relatively large. On the other hand, when the radial fixed frequency peak of the lower part of the liquid reservoir is large, once its structural mode is excited and causes fixed frequency resonance, the noise peak of the compressor at the fixed frequency will be abnormally large, which will cause the noise and vibration of the entire compressor to deteriorate seriously.

[0004] Since the rotary compressor in the prior art has a lower part of the liquid accumulator, especially the outlet elbow part, which is in a free swinging state and is the connection part with the compressor pump body cavity, its radial vibration relative to the shell is relatively large; on the other hand, when the radial fixed frequency peak of the lower part of the liquid accumulator is large, once its structural mode is excited and causes fixed frequency resonance, the noise peak of the compressor at the fixed frequency will be abnormally large, which will lead to technical problems such as serious deterioration of the noise and vibration of the entire compressor. Therefore, the present invention studies and designs a cylinder, a compressor and an air conditioner. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the outlet bend pipe at the lower part of the liquid reservoir vibrates relatively greatly relative to the shell due to being in a free swinging state, thereby generating relatively large noise, thereby providing a compressor assembly and an air conditioner.

DETAILED DESCRIPTION

[0030] like Figure 2-3 As shown, the present invention provides a compressor assembly, which includes:

[0031] The compressor body 1, the liquid reservoir 2, the air outlet bend 26, the shell intake pipe 132 and the air outlet bend damper 5, one end of the air outlet bend 26 is connected to the interior of the liquid reservoir 2, and the other end is connected to the shell intake pipe 132, the shell intake pipe 132 is fixed on the compressor body 1, and the shell intake pipe 132 is connected to the interior of the compressor body 1, the air outlet bend damper 5 is arranged at the position where the air outlet bend 26 is connected to the shell intake pipe 132, and the air outlet bend damper 5 can limit the air outlet bend 26 along the radial direction and circumferential direction of the shell intake pipe 132.

[0032] The present invention provides an outlet bend damper at the junction of the outlet bend and the housing intake pipe, thereby limiting the outlet bend in the radial and circumferential directions of the housing intake pipe, optimizing the constraint form of the liquid reservoir for the rotary compressor, improving the radial vibration mode of the lower portion of the liquid reservoir, and reducing the degree of resonance of the compressor as a whole caused by the structural modal excitation of the outlet bend at the lower portion of the liquid reservoir, thereby effectively reducing the vibration and noise of the compressor. The liquid reservoir damper of the present invention is a soft material with a certain elasticity, such as a composite rubber, and the damper achieves an assembly relationship of interference fit with the liquid reservoir bend (i.e., the outlet bend 26, the same below), the housing intake pipe, and the mounting boss through its elastic properties. Through the structure of the present invention, the radial and circumferential constraints on the liquid reservoir bend are increased, the vibration mode of the lower portion of the liquid reservoir is greatly improved, and the degree of resonance of the compressor as a whole caused by the structural modal excitation of the outlet bend at the lower portion of the liquid reservoir is reduced, thereby effectively reducing the vibration and noise of the compressor.

[0033] like Figure 1 The liquid reservoir of a conventional rotary compressor is mounted on one side of the compressor body, generating swinging vibrations as the compressor's rotating components rotate. The lower portion of the liquid reservoir, particularly the outlet elbow, is in a free-swinging state and connects to the compressor's pump body cavity, so its radial vibration relative to the casing is relatively large. On the other hand, if the radial fixed-frequency peak of the lower portion of the liquid reservoir is large, once its structural mode is excited and causes fixed-frequency resonance, the noise peak at the fixed-frequency position of the compressor will be abnormally large, resulting in a serious deterioration in the noise and vibration of the entire compressor.

[0034] The present invention incorporates a vibration damper made of a flexible, elastic material, such as a composite rubber, at the outlet elbow where the liquid reservoir connects to the compressor housing. Simultaneously, a matching vibration damper structure is provided on the housing. This optimizes the constraints of the connection and the resonant modes of the liquid reservoir elbow, providing vibration damping and noise reduction. This optimizes the constraints of the liquid reservoir for the rotary compressor, improves the radial vibration modes of the reservoir's lower portion, and reduces the overall compressor resonance caused by the modal excitation of the outlet elbow structure at the reservoir's lower portion, thereby effectively reducing compressor vibration and noise.

[0035] The present invention focuses on the above-mentioned problems and proposes an innovative structure of the liquid reservoir outlet elbow vibration damper, optimizes the constraint form of the liquid reservoir, improves the radial vibration mode of the lower part of the liquid reservoir, and reduces the resonance degree of the compressor as a whole caused by the modal excitation of the liquid reservoir's lower outlet elbow structure, thereby effectively reducing the vibration and noise of the compressor.

[0036] A rolling rotor compressor is provided, comprising a compressor body and a liquid reservoir, among other main components. The liquid reservoir is connected to the compressor body via an outlet elbow of the liquid reservoir and an air intake pipe of the compressor body's shell. The liquid reservoir elbow comprises a first elbow coaxial with the liquid reservoir body and a second elbow coaxial with the air intake pipe of the shell. The connection between the outlet elbow and the compressor body is equipped with a liquid reservoir outlet elbow damper. The compressor body is provided with a mounting boss for the liquid reservoir damper on its outer shell, corresponding to the connection between the outlet elbow and the compressor body.

[0037] The accumulator outlet elbow vibration damper has a columnar structure with a first end face, a second end face, and an open face. The first end face and the open face are designed with a concave semi-cylindrical mating channel that connects them. The second end face mates with the end face of the vibration damper mounting boss on the compressor body. This design addresses the special structure of the accumulator elbow and its mating with the compressor housing in existing technologies, achieving better restraint and vibration and noise reduction.

[0038] The through-connected concave mating channel (opening 50) includes a first mating hole, a second mating hole, and a third mating hole. The first mating hole is provided on the first end face, and the second mating hole and the third mating hole are provided on the opening face, respectively forming an interference fit with the first elbow, the second elbow, and the housing intake pipe.

[0039] The vibration damper is made of a soft elastic material such as composite rubber, and the vibration damper realizes an interference fit assembly relationship with the liquid reservoir elbow, the shell suction pipe and the mounting boss through its elastic properties.

[0040] In some embodiments, the outlet elbow vibration damper 5 is a columnar structure, including a first end surface 55 at one axial end thereof and a second end surface 56 at the other axial end thereof. The outlet elbow vibration damper 5 also includes an opening 50, which faces the outlet elbow 26 and can be clamped to the outer circumference of the outlet elbow 26 through the opening 50. This is the preferred structural form of the outlet elbow vibration damper of the present invention, namely, a columnar structure with an opening formed therethrough, through which the outlet elbow can be clamped, effectively achieving the effect of clamping, fixing, and positioning the outlet elbow, and effectively reducing vibration of the outlet elbow.

[0041] In some embodiments, the opening 50 is formed by cutting a portion of the cylindrical structure along one circumferential side in the axial direction. This is the preferred method of forming the opening of the present invention. The opening is formed by cutting a portion of the cylindrical structure along the axial direction at one circumferential end, preferably the lower end as shown in the figure, so that the opening can form a clamping effect on the outlet elbow.

[0042] In some embodiments, a mounting boss 131 is further provided on the compressor body 1 at the position of the casing intake pipe 132. The mounting boss 131 is sleeved around the outer circumference of the casing intake pipe 132, and the second end face 56 of the outlet elbow damper 5 is clamped onto the mounting boss 131. The present invention also utilizes the provision of the mounting boss to simultaneously secure the casing intake pipe and secure the second end face of the outlet elbow damper, thereby effectively securing the outlet elbow damper to the compressor body and further firmly positioning and securing the outlet elbow, thereby reducing its vibration.

[0043] In some embodiments, the air outlet bend 26 includes a first bend 261 and a second bend 262, the first bend 261 and the second bend 262 are connected, the first bend 261 is coaxial with the liquid reservoir 2, and the second bend 262 is coaxial with the shell intake pipe 132, and the opening 50 includes a third mating hole 53 and a second mating hole 52 connected in the axial direction, the third mating hole 53 is clamped on the shell intake pipe 132, and the second mating hole 52 is clamped on the outside of the second bend 262, and an inwardly concave first mating hole 51 is opened on the first end face 55, and the first mating hole 51 is clamped on the first bend 261. This is a further preferred structural form of the air outlet bend of the present invention, and a preferred structural form of the air outlet bend damper, that is, the air outlet bend includes a first and a second bend, and the opening of the air outlet bend damper includes a first matching hole, a second matching hole and a third matching hole, the first matching hole faces the first bend and is clipped together with the first bend, the second matching hole faces the second bend and is clipped together with the second bend, and the third matching hole is clipped together with the shell intake pipe, so that the two sections of the air outlet bend and the position connected to the shell intake pipe are firmly abutted, further improving the limiting effect on multiple directions of the air outlet bend and reducing the vibration of the air outlet bend.

[0044] like Figure 1 、 Figure 1-1The figures show the appearance structure and cross-sectional structure diagram of the assembly structure of a conventional rolling rotor compressor. A conventional rolling rotor compressor is mainly composed of a compressor body 1 and a liquid reservoir 2. The compressor body 1 is mainly composed of a pump body assembly 11, a motor assembly 12, and a shell 13, and the liquid reservoir 2 is mainly composed of an air inlet pipe 21, a filter 22, a straight pipe 23, a cylinder 24, a partition 25, an air outlet elbow 26, etc. The liquid reservoir 2 is arranged on one side of the compressor body 1 and is fixed to the liquid reservoir bracket 3 on the shell 13 of the compressor body 1 through the liquid reservoir pressure plate 4. The air inlet pipe 21 is connected to the system pipeline, and the air outlet elbow 26 is connected to the shell suction pipe 132 of the compressor body 1. The high-temperature and high-pressure refrigerant gas generated by the compressor pump body assembly 11 enters the system pipeline from the compressor outlet 14, and is converted into low-temperature and low-pressure gas through condensation and evaporation in the system pipeline. It then enters the liquid reservoir 2 through the liquid reservoir inlet pipe 21, and after being filtered by the liquid reservoir filter 22, it flows through the liquid reservoir straight pipe 23 and the air outlet elbow 26 and enters the pump body assembly 11, realizing the periodic circulation working process of the compressor and the system pipeline.

[0045] Since the liquid reservoir 2 of the above-mentioned conventional rotor compressor is installed on one side of the compressor body 1, the swing vibration generated by the rotation of the rotating parts of the compressor is one of the main sources of vibration of the liquid reservoir. The swing vibration of the liquid reservoir cylinder 24 can be effectively improved by the fixed constraint of the liquid reservoir bracket 3. The lower part of the liquid reservoir, especially the exhaust elbow 26, is in a free swinging state and is the connection part with the pump body assembly 11, so its radial vibration is relatively large. On the other hand, when the radial fixed frequency peak of the lower part of the liquid reservoir 2 is large, once its structural mode is excited and causes fixed frequency resonance, the noise peak of the compressor at the fixed frequency will be abnormally large, which will cause the noise and vibration of the entire compressor to deteriorate seriously.

[0046] The present invention focuses on the above-mentioned problems and proposes an innovative structure of a vibration damping member for an outlet bend of a liquid reservoir, which improves its vibration noise by optimizing the constraint form of the position of the bend of the liquid reservoir.

[0047] like Figure 2 FIG. 1 is a schematic diagram of the compressor structure of the present invention.

[0048] Figure 2 、 Figure 2-1 、 Figure 2-2They are respectively a schematic diagram of the assembly structure of the whole compressor of the present invention, a partial cross-sectional view, and an enlarged partial cross-sectional view. The rolling rotor compressor of the present invention is composed of main components such as a compressor body 1 and a liquid reservoir 2. The liquid reservoir 2 is connected to the compressor body 1 through the liquid reservoir outlet bend 26 and the compressor body shell intake pipe 132. The outlet bend 26 is composed of a first bend 261 coaxial with the liquid reservoir body and a second bend 262 coaxial with the shell intake pipe. The connection portion between the liquid reservoir outlet bend 26 and the compressor body 1 is equipped with a liquid reservoir outlet bend damper 5. A liquid reservoir damper mounting boss 131 is designed on the outer shell 13 of the compressor body 1 corresponding to the connection portion between the liquid reservoir outlet bend 26 and the compressor body 1.

[0049] Figure 2-3 , 2-4, 2-5 are schematic diagrams of the structure of the liquid reservoir vibration damping component of the present invention.

[0050] The cross-sectional view, A-direction view, and B-direction view of the liquid reservoir damper of the present invention. The outlet bend damper 5 is a columnar structure having a first end face 55, a second end face 56, and an opening face 54, wherein the first end face 55 and the opening face 54 are designed with a through-connected concave semi-cylindrical mating channel (opening 50), and the second end face 56 is mated with the end face of the damper mounting boss 131 on the compressor body 1. The concave mating channel (opening 50) includes a first mating hole 51, a second mating hole 52, and a third mating hole 53, wherein the first mating hole 51 is provided on the first end face 55, and the second mating hole 52 and the third mating hole 53 are provided on the opening face 54, and are interference fit with the first bend 261, the second bend 262, and the shell intake pipe 132, respectively. Furthermore, the outlet elbow damper 5 of the present invention is made of a soft material with a certain degree of elasticity, such as composite rubber. Its elastic properties enable an interference fit between the outlet elbow 26, the housing intake pipe 132, and the mounting boss 131. This innovative structure increases radial and circumferential constraints on the outlet elbow 26, significantly improving the vibration modes of the lower portion of the reservoir 2 and reducing the overall compressor resonance caused by the structural modal excitation of the outlet elbow 26 at the reservoir 2, thereby effectively reducing compressor vibration and noise.

[0051] In some embodiments, the first mating hole 51 is a concave semi-cylindrical hole, the second mating hole 52 is a concave semi-cylindrical hole, and the third mating hole 53 is a concave semi-cylindrical hole. This is the preferred structural form of the first, second, and third mating holes of the present invention. The concave semi-cylindrical holes can respectively mate with the outer circumferences of the three cylindrical tube segments to effectively achieve a large-area snap-fit, improve the secure fit, enhance the position limiting effect on the outlet elbow, and enhance the vibration reduction effect.

[0052] In some embodiments, the outlet elbow 26 further includes a third straight pipe 263, at least a portion of which is inserted into the housing intake pipe 132, with one end of the third straight pipe 263 connected to one end of the second elbow 262. This is a further preferred structural form of the outlet elbow of the present invention. The third straight pipe enables it to be inserted into the housing intake pipe to form a secure connection therewith, and the outlet elbow vibration damper can effectively limit and interfere with this portion of the structure to reduce vibration of the outlet elbow.

[0053] In some embodiments, the outlet elbow vibration damper 5 is interference-fitted with the outlet elbow 26 and the housing intake pipe 132, respectively. When the outlet elbow 26 includes a first elbow 261 and a second elbow 262, and the opening 50 includes a first mating hole 51, a second mating hole 52, and a third mating hole 53, the first mating hole 51 is interference-fitted with the first elbow 261, the second mating hole 52 is interference-fitted with the second elbow 262, and the third mating hole 53 is interference-fitted with the housing intake pipe 132. The present invention enhances the fixing effect of the outlet elbow by the interference fit between the outlet elbow vibration damper and the multi-segment pipe, thereby improving the vibration reduction effect of the outlet elbow.

[0054] In some embodiments, the outlet elbow vibration damper 5 is made of elastic material, preferably composite rubber.

[0055] Figure 3 The following table shows the comparison of the effects of the inventor's application of the innovative structure of the present invention on a compressor prototype of a specific model. The red line represents the noise spectrum of a conventional structure, and the green line represents the noise spectrum of the innovative structure of the present invention. The spectrum comparison results show that the modal frequency of the outlet elbow of the liquid reservoir of the specific model prototype (obtained from modal testing) at 1970 Hz and the noise peak in the frequency band near this frequency point are significantly reduced, thereby significantly optimizing the total noise value in the low-frequency band (within 2 kHz) and the tangential vibration of the liquid distributor of the structural prototype of the present invention. As shown in the table below, under the national standard 80 Hz operating condition, the total noise value within 2 kHz and the tangential vibration of the liquid distributor of the conventional structure of a specific model and the structural prototype of the present invention are compared. Compared with the conventional compressor, the noise of the compressor of the technical solution of the present invention within 2 kHz is reduced by 3.68 dBA, and the tangential vibration acceleration is reduced by 4.25 dBA.
