Description

Technical Field

[0002] Currently, if Figure 1 , Figure 2 and Figure 7 As shown, the conventional multi-cylinder rotor compressor is mainly composed of a compressor body and a liquid reservoir, and the liquid reservoir is arranged on one side of the compressor body. The liquid reservoir pressure plate is fixed to the liquid reservoir bracket on the shell of the compressor body, and the air outlet elbow is connected to the corresponding pump body suction hole of the compressor body through its pump body suction pipe matching section, and the assembly matching section of the air outlet elbow and the compressor pump body suction pipe is coaxially matched and welded.

[0003] However, when assembling the outlet elbow with the compressor pump body suction pipe, the existing outlet elbow has no effective constraint in the radial direction of the compressor, which can easily lead to the tilt of the reservoir assembly in the actual production process, and then the outer surface of the reservoir cylinder cannot be optimally fitted with the bracket, which ultimately affects the assembly quality of the compressor and the consistency of its vibration and noise. In addition, when the radial fixed frequency peak of the lower part of the 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 compressor to deteriorate seriously.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] like Figures 3 to 6 As shown, the first embodiment of the utility model provides a liquid reservoir, which includes a cylinder 1 and a first air outlet pipe 4. A first socket 11 is provided on the cylinder 1; the cylinder 1 is installed on the base 3 to be installed through a connecting frame 2, and the connection between the connecting frame 2 and the cylinder 1 is spaced apart from the first socket 11. The first air outlet pipe 4 includes a main body section 41 and a first contraction section 42 that are connected to each other, and at least part of the outer edge of the main body section 41 protrudes from the outer edge of the first contraction section 42; one end of the main body section 41 away from the first contraction section 42 is inserted at the first socket 11, the main body section 41 is fixedly connected to the cylinder 1, and the first contraction section 42 is inserted into the first installation hole 31 on the base 3 to be installed, and the connection between the first contraction section 42 and the main body section 41 abuts against the end surface surrounding the first installation hole 31. Among them, the cylinder 1 has a first central axis, and the foundation 3 to be installed has a second central axis; the distance between the connection between the main section 41 and the first shortened section 42 and the first central axis is L2, and the distance between the connection between the main section 41 and the first shortened section 42 and the second central axis is L1; when the cylinder 1 and the foundation 3 to be installed are both in a vertical placement state, the first central axis is parallel to the second central axis, and the distance between the first central axis and the second central axis is L0; -0.5mm≤L1+L2-L0≤0.5mm.

[0048] The liquid storage device provided by the first embodiment of the utility model can be provided with the outer edge of the main section 41 at least partially protruding from the outer edge of the first contraction section 42, so that the connection between the first contraction section 42 and the main section 41 can abut against the end surface surrounding the first mounting hole 31, thereby realizing the positioning of the installation position of the first air outlet pipe 4 relative to the first mounting hole 31, and then constraining the radial direction of the first air outlet pipe 4 relative to the first mounting hole 31, so that the posture of the cylinder body 1 installed on the base 3 to be installed is close to the vertical placement posture of the cylinder body 1, thereby realizing the limitation of the distance between the connection between the first contraction section 42 and the main section 41 and the first socket 11, so that it is as consistent as possible with the preset state when placed vertically. Specifically, since -0.5mm≤L1+L2-L0≤0.5mm, through such a range limitation, it can effectively ensure that the cylinder body is in a vertical installation state as much as possible, and effectively avoid the problems of low assembly quality and poor shock absorption effect caused by tilting. Therefore, the liquid reservoir provided in this embodiment can solve the technical problem in the prior art that the liquid reservoir assembly is prone to significant tilt.

[0049] In this embodiment, preferably, -0.2 mm ≤ L1 + L2 - L0 ≤ 0.2 mm, so as to better prevent the liquid reservoir assembly from tilting.

[0050] More preferably, L0=L1+L2.

[0051] Specifically, the vertical placement state of the cylinder 1 refers to the posture of the cylinder 1 when the cylinder 1 is placed on the ground, and the vertical placement state of the foundation 3 to be installed refers to the posture of the foundation 3 to be installed when the foundation 3 to be installed is placed on the ground. Specifically, the ground here can preferably be understood as a horizontal plane or an inclined plane with an angle of less than or equal to 10° to the horizontal plane.

[0052] Specifically, when the cylinder 1 and the foundation to be installed are in a vertical placement state, the connection between the main section 41 and the first shortened section 42 is parallel to the first center axis; when the cylinder 1 and the foundation to be installed are inclined at a small angle, "the distance between the connection between the main section 41 and the first shortened section 42 and the first center axis is L2" can be understood as the distance between the intersection between the first center axis and the bottom surface of the cylinder 1 to the surface where the connection between the main section 41 and the first shortened section 42 is located.

[0053] Specifically, the first socket 11 may be a round socket.

[0054] Specifically, the end surface of the main body section 41 close to one end of the first contraction section 42 forms the connection between the main body section 41 and the first contraction section 42. In this way, a step surface for abutting against the end surface surrounding the first mounting hole 31 can be formed at the connection between the main body section 41 and the first contraction section 42, thereby effectively positioning the installation position of the first air outlet pipe 4 relative to the first mounting hole 31.

[0055] like Figure 4 As shown, in the second embodiment of the present utility model, the first air outlet pipe 4 also includes a first transition section 43, the two ends of the first transition section 43 are respectively connected to the main section 41 and the first contraction section 42, and the first transition section 43 forms the connection between the main section 41 and the first contraction section 42. Along the extension direction from the first contraction section 42 to the main section 41, the cross-sectional area of ​​the first transition section 43 gradually increases. With such a structural setting, it is possible to facilitate the processing of the first air outlet pipe 4, and at the same time, it is possible to ensure that the connection between the main section 41 and the first contraction section 42 is abutted against the end surface surrounding the first mounting hole 31.

[0056] Specifically, the angle between the transition surface of the first transition section 43 and the axis of the first contraction section 42 is β, 45°≤β≤90°. With such a structural arrangement, the processing convenience of the first air outlet pipe 4 can be ensured, and the abutment effect between the connection between the main section 41 and the first contraction section 42 and the end surface surrounding the first mounting hole 31 can be ensured.

[0057] In this embodiment, the cylinder 1 is further provided with a second socket 12 spaced apart from the first socket 11. The liquid reservoir further includes a second air outlet pipe 5, which includes a main body section 51 and a constricted section 52 connected to each other, at least a portion of the outer edge of the main body section 51 protrudes from the outer edge of the constricted section 52, an end of the main body section 51 away from the constricted section 52 is inserted into the second socket 12, the main body section 51 is fixedly connected to the cylinder 1, and an end of the constricted section 52 away from the main body section 51 is used to be inserted into the second mounting hole 32 of the base 3 to be mounted, and the connection between the constricted section 52 and the main body section 51 abuts against the end surface surrounding the second mounting hole 32. With such a structural setting, the outer edge of the body section 51 can at least partially protrude from the outer edge of the necking section 52, so that the connection between the necking section 52 and the body section 51 can abut against the end surface surrounding the second mounting hole 32, thereby realizing the positioning of the installation position of the second air outlet pipe 5 relative to the second mounting hole 32, and then constraining the radial direction of the second air outlet pipe 5 relative to the second mounting hole 32. On the basis of the setting of the first air outlet pipe 4, it is further ensured that the posture of the cylinder 1 installed on the base 3 to be installed is close to the vertical placement posture of the cylinder 1. The above structure can also facilitate the connection of the two cylinders separately, while improving the support strength and support stability of the cylinder 1, so as to better make the cylinder 1 in a vertical placement state as much as possible.

[0058] Specifically, there is at least one second air outlet pipe 5. When there is one second air outlet pipe 5, it corresponds to a two-cylinder compressor; when there are two second air outlet pipes 5, it corresponds to a three-cylinder compressor; when there are three second air outlet pipes 5, it corresponds to a four-cylinder compressor.

[0059] Specifically, the second socket 12 can be a round socket.

[0060] Specifically, the first socket 11 and the second socket 12 are arranged at intervals on the bottom surface of the cylinder 1. In this way, the arrangement of the first air outlet pipe 4 and the second air outlet pipe 5 can better prevent the cylinder 1 from being tilted greatly.

[0061] Specifically, the first socket 11 and the second socket 12 are arranged at intervals in the horizontal direction. In this way, the first air outlet pipe 4 and the second air outlet pipe 5 can be better prevented from causing a large tilt of the cylinder body 1.

[0062] Specifically, the cross-sectional areas of the narrowing section 52 and the first narrowing section 42 are both circular, and the outer diameter of the narrowing section 52 is equal to the outer diameter of the first narrowing section 42 .

[0063] Specifically, the first socket 11 and the second socket 12 are arranged at intervals on the bottom surface of the cylinder 1. The first socket 11 and the second socket 12 are arranged at intervals in the horizontal direction. Alternatively, the first socket 11 and the second socket 12 are arranged at intervals on the bottom surface of the cylinder 1. The cross-sectional areas of the constricted section 52 and the first constricted section 42 are both circular, and the outer diameter of the constricted section 52 is equal to the outer diameter of the first constricted section 42. Alternatively, the first socket 11 and the second socket 12 are arranged at intervals in the horizontal direction. The cross-sectional areas of the constricted section 52 and the first constricted section 42 are both circular, and the outer diameter of the constricted section 52 is equal to the outer diameter of the first constricted section 42. Alternatively, the first socket 11 and the second socket 12 are arranged at intervals on the bottom surface of the cylinder 1. The first socket 11 and the second socket 12 are arranged at intervals in the horizontal direction. The cross-sectional areas of the constricted section 52 and the first constricted section 42 are both circular, and the outer diameter of the constricted section 52 is equal to the outer diameter of the first constricted section 42. In this way, the first air outlet pipe 4 and the second air outlet pipe 5 can be better prevented from causing a large tilt of the cylinder body 1 .

[0064] In this embodiment, the second socket 12 is located on the side of the first socket 11 close to the base 3 to be installed, the necking section 52 is located above the first necking section 42, and the outer diameter of the main section 41 is greater than the outer diameter of the main section 51. In this way, the force balance at the connection between the cylinder 1 and the first and second air outlet pipes 4 and 5 can be improved, and the possibility of tilting of the cylinder 1 can be further reduced.

[0065] like Figure 4As shown, the first air outlet pipe 4 also includes a tapered connecting section, the two ends of which are respectively connected to the main section 41 and the first contraction section 42, and the tapered connecting section forms the connection between the main section 41 and the first contraction section 42; along the extension direction from the first contraction section 42 to the main section 41, the cross-sectional area of ​​the tapered connecting section gradually increases; the angle between the tapered connecting section and the axis of the first contraction section 42 is β, 45°≤β≤90°. Specifically, the first transition section 43 can be the tapered connecting section. By adopting the above-mentioned setting of the tapered connecting section, it is easy to form an effective transition chamfer structure, which is convenient for processing, and the optimization of the constraint effect of the first air outlet pipe 4 relative to the radial direction of the compressor body is achieved, ensuring the abutment limiting effect, which is conducive to better reducing the inclination of the liquid reservoir.

[0066] The end surface of the main body section 51 near one end of the necking section 52 forms the connection between the main body section 51 and the necking section 52. In this way, a step surface for abutting against the end surface surrounding the second mounting hole 32 can be formed at the connection between the main body section 51 and the necking section 52, thereby effectively positioning the installation position of the second air outlet pipe 5 relative to the second mounting hole 32.

[0067] like Figure 4 As shown, in the second embodiment of the present utility model, the second air outlet pipe 5 further includes a second transition section 53, the two ends of which are respectively connected to the main body section 51 and the necking section 52, and the second transition section 53 forms the connection between the main body section 51 and the necking section 52; along the extension direction from the necking section 52 to the main body section 51, the cross-sectional area of ​​the second transition section 53 gradually increases. With such a structural setting, the processing of the second air outlet pipe 5 can be facilitated, and at the same time, the abutment positioning between the connection between the main body section 51 and the necking section 52 and the end surface surrounding the second mounting hole 32 can be ensured.

[0068] In this embodiment, the first air outlet pipe 4 further includes a second shortened section 44, which is connected to the main section 41, and is located at one end of the main section 41 away from the first shortened section 42. At least part of the outer edge of the main section 41 protrudes from the outer edge of the second shortened section 44, and the second shortened section 44 is inserted at the first socket 11. The main section 41 is fixedly connected to the cylinder 1 through the second shortened section 44. With such a structural arrangement, the positioning and limitation of the connection position of the first air outlet pipe 4 relative to the first socket 11 can be strengthened through the arrangement of the second shortened section 44, and the risk of the liquid reservoir being tilted during assembly can be further reduced.

[0069] Specifically, the outer diameter of the main section 41 is D, the outer diameter of the first shrinking section 42 is d1, and the outer diameter of the second shrinking section 44 is d2, wherein D-d1≥2mm. In this way, it is possible to ensure that there is an effective abutment limiting area between the connection between the main section 41 and the first shrinking section 42 and the end surface surrounding the first mounting hole 31, thereby preventing the connection between the main section 41 and the first shrinking section 42 and the end surface surrounding the first mounting hole 31 from failing to form an effective abutment limit when assembly deformation occurs due to too small abutment area. At the same time, it is also necessary to avoid the difference between D and d1 being too large, which would increase the difficulty of the shrinking process.

[0070] Specifically, the outer diameter of the main section 41 is D, the outer diameter of the first shrinking section 42 is d1, and the outer diameter of the second shrinking section 44 is d2, wherein D-d2≥2mm. In this way, it is possible to ensure that there is an effective abutment limiting area between the connection between the main section 41 and the second shrinking section 44 and the end surface surrounding the first socket 11, and avoid that when the abutment area is too small, the connection between the main section 41 and the second shrinking section 44 and the end surface surrounding the first socket 11 cannot form an effective abutment limit when assembly deformation occurs. At the same time, it should also be avoided that the difference between D and d2 is too large, which increases the difficulty of the shrinking process.

[0071] Specifically, the outer diameter of the main section 41 is D, the outer diameter of the first contraction section 42 is d1, and the outer diameter of the second contraction section 44 is d2, wherein D-d1≥2mm, D-d2≥2mm. In this way, it is possible to ensure that there is an effective contact limiting area between the connection between the main section 41 and the first contraction section 42 and the end surface surrounding the first mounting hole 31, so as to avoid that when the assembly deformation occurs due to too small abutment area, the connection between the main section 41 and the first contraction section 42 and the end surface surrounding the first mounting hole 31 cannot form an effective abutment limit. At the same time, it is also possible to ensure that there is an effective contact limiting area between the connection between the main section 41 and the second contraction section 44 and the end surface surrounding the first socket 11, so as to avoid that when the assembly deformation occurs due to too small abutment area, the connection between the main section 41 and the second contraction section 44 and the end surface surrounding the first socket 11 cannot form an effective abutment limit. At the same time, it should also be avoided that the difference between D and d1 or the difference between D and d2 is too large to increase the difficulty of the shrinking process.

[0072] Specifically, the outer diameter of the first contraction section 42 is equal to the outer diameter of the contraction section 52. In this way, the first air outlet pipe 4 and the second air outlet pipe 5 can be manufactured uniformly.

[0073] Specifically, the inner diameter of the first socket 11 is equal to the inner diameter of the second socket 12. In this way, the production and manufacturing of the cylinder 1 is facilitated.

[0074] Embodiment 3 of the present invention provides a compressor, which includes a compressor body, a connecting frame 2 and the above-mentioned liquid reservoir, wherein the connecting frame 2 is mounted on the compressor body, and the liquid reservoir is mounted on the compressor body through the connecting frame 2.

[0075] Specifically, the compressor body is the above-mentioned base to be installed 3. The compressor can be suitable for an air conditioner.

[0076] Specifically, the connecting frame 2 also includes a connecting pressure plate 21, which is an annular plate. The annular plate encloses a accommodating space, and the accommodating space is adapted to the size of the cylinder 1. The annular plate is used to fix the cylinder 1 in the accommodating space. When the cylinder 1 is in a vertical placement state, the annular plate fits tightly against the outer surface of the cylinder 1.

[0077] Specifically, the compressor body includes a pump body assembly 36 , a motor assembly 35 , a housing 34 , etc. The liquid reservoir also includes an air intake pipe 6 , a filter screen 13 , a straight pipe 14 , and a partition plate 15 .

[0078] Specifically, the compressor may be a single-stage, two-stage, variable displacement rotor compressor.

[0079] Specifically, the high-temperature and high-pressure refrigerant gas generated by the pump body assembly 36 enters the system pipeline from the compressor outlet 33, is converted into low-temperature and low-pressure gas through condensation and evaporation in the system pipeline, and then enters the liquid reservoir through the liquid reservoir inlet pipe 6. After being filtered by the liquid reservoir filter 13, it flows through the liquid reservoir straight pipe 14, the first outlet pipe 4 and the second outlet pipe 5, and enters the compressor pump body assembly 36, thereby realizing the periodic circulation working process of the compressor and the system pipeline.

[0080] like Figure 7 and Figure 8 As shown, the conventional compressor in the prior art and the compressor provided by the third embodiment of the present invention were tested to verify the noise and vibration consistency control effect, and the specific data are shown in the following table. Among them, two prototypes were selected for the conventional compressor in the prior art, and two prototypes were also selected for the compressor provided by the third embodiment of the present invention.

[0081]

[0082]

[0083] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by optimizing the liquid reservoir bend structure, improving the assembly constraint form of the liquid reservoir, and improving the assembly consistency of the liquid reservoir, the radial vibration mode of the lower part of the liquid reservoir is improved, and the resonance degree of the whole compressor caused by the modal excitation of the lower air outlet bend structure of the liquid reservoir is reduced, thereby effectively ensuring the vibration consistency of the compressor liquid reservoir while reducing the vibration and noise of the compressor.
