Description

Technical Field

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

[0002] When the compressor is working, it will inhale, compress and exhaust periodically. When the compressor compresses the gas, the compression chamber volume will continue to decrease, which will cause pressure pulsation. The high-speed flow of gas generated by the compressor when exhausting will also cause pressure pulsation, causing the compressor to produce multi-body vibration, which will not only increase the wear of the contact surfaces between the components, reduce the service life of the components, increase power consumption, and reduce energy efficiency, but also the vibration noise caused by vibration will affect the comfort of use. In addition, the flange assembly is one of the core components of the compressor pump body and an important component on the vibration transmission path.

[0003] In order to reduce vibration noise, the flange body of the flange structure of the existing compressor is provided with a silencer groove, which is connected to the exhaust port, and the silencer groove is connected to a number of guide grooves, and the other end of each guide groove is connected to a silencer resonance cavity with different sound-absorbing bands, so that the gas containing noise of different frequency bands generated by the exhaust of the compressor is discharged from the exhaust port, and after the gas flows through the silencer groove provided on the flange body, it disperses and flows into a number of guide grooves connected to the silencer groove, and the gas flows from each guide groove into the silencer resonance cavity with different sound-absorbing bands, and the noise peaks of different frequency bands can be better eliminated by combining different silencer resonance cavities. However, the silencer grooves, guide grooves and silencer resonance cavities provided in communication with each other on the flange body of the existing compressor can only eliminate the noise peaks of different frequency bands to a certain extent, but do not have a significant effect on the overall reduction of noise, resulting in a limited degree of vibration energy attenuation, and the vibration energy and vibration noise are still large in actual operation. Summary of the invention

[0004] The first object of the present invention is to provide a flange assembly that can effectively attenuate the vibration energy and vibration noise generated by the crankshaft of the compressor as a whole, and can effectively prevent heat conduction, thereby improving work energy efficiency and work efficiency, and extending product service life and comfort of use.

[0005] A second object of the present invention is to provide a compressor with the above flange assembly.

[0006] A third object of the present invention is to provide an air conditioner having the above compressor.

[0007] A fourth object of the present invention is to provide a household appliance having the above compressor.

[0008] In order to achieve the first purpose of the present invention, the present invention provides a flange assembly, including a flange plate, a cavity is arranged on the annular rim disk portion of the flange plate, and the annular rim disk portion is used to be sleeved on the crankshaft of the compressor, the cavity is filled with a plurality of damping particles, and the plurality of damping particles can move in the cavity, the flange assembly also includes a silencer cover, the annular rim disk portion is provided with a groove on its axial outer end face, the silencer cover is arranged on the outer end face of the annular rim disk portion and covers the groove to form a cavity, the silencer cover is adjacent to the inner end face of the annular rim disk portion and is provided with a silencer cavity, and the silencer cavity is communicated with the exhaust port on the annular rim disk portion.

[0009] It can be seen from the above scheme that when the compressor is running and generates multi-body vibration, the vibration is transmitted to the flange of the flange assembly of the present invention through the crankshaft. Since the cavity on the annular disk portion of the flange is filled with multiple movable damping particles, when it is in low-frequency vibration, there is mainly friction movement between the multiple damping particles and between the multiple damping particles and the cavity wall of the cavity, and when it is in high-frequency vibration, there is mainly collision movement between the multiple damping particles and between the multiple damping particles and the cavity wall of the cavity. Therefore, along with the transmission of vibration, the multiple damping particles in the cavity vibrate accordingly, so that the multiple damping particles continuously collide and rub with the cavity wall of the cavity, and at the same time, the multiple damping particles continuously collide and rub with each other, so as to convert the transmitted vibration energy into the kinetic energy of the damping particles, thereby greatly consuming and attenuating the vibration energy generated by the crankshaft, thereby reducing the vibration noise generated by the crankshaft. At the same time, the inner end surface of the silencer cover adjacent to the annular disk portion is provided with a silencer cavity, and the silencer cavity is connected to the exhaust port on the annular disk portion, so as to further attenuate the vibration energy and vibration noise generated by the crankshaft. Furthermore, the cavity on the annular disk portion of the flange of the flange assembly of the present invention is filled with air and a plurality of movable damping particles, and the thermal conductivity of the damping particles and the air is lower than the thermal conductivity of the flange body. Thus, the cavity filled with air and a plurality of movable damping particles can play a heat insulating role to prevent heat conduction from the exhaust chamber of the compressor to the intake chamber, thereby reducing the intake temperature rise of the compressor, increasing the intake volume of the compressor, and thereby improving the compression efficiency of the compressor.

[0010] Therefore, the flange assembly of the present invention can effectively attenuate the vibration energy and vibration noise generated by the crankshaft of the compressor as a whole, and can effectively prevent heat conduction, thereby improving work energy efficiency and work efficiency, and extending the service life and comfort of the compressor product.

[0011] A preferred solution is that the cavity is arranged in an arc-shaped cavity extending in the circumferential direction of the annular rim disk portion, and both ends of the cavity in the circumferential direction of the annular rim disk portion are in a rounded arc-shaped transition.

[0012] A further solution is that the cross section of the cavity in the radial direction of the annular rim disk portion is arranged to be circular.

[0013] A further solution is that the number of cavities includes at least two, each cavity is filled with multiple damping particles with the same or different filling rates; the multiple cavities are arranged in the circumferential direction of the annular rim disk portion; and / or the multiple cavities are arranged in the radial direction of the annular rim disk portion.

[0014] A further solution is that the filling rate of the plurality of damping particles filled in the cavity is between 50% and 80%.

[0015] A further solution is that the height of the cavity in the axial direction of the annular rim disk portion is equal to or less than 1 / 2 of the height of the annular rim disk portion; and / or the width of the cavity in the radial direction of the annular rim disk portion is between 3 mm and 6 mm; and / or the central angle of the arc of the cavity extending in the circumferential direction of the annular rim disk portion is equal to or less than 60°.

[0016] A further solution is that the diameter of the damping particles is between 0.01 mm and 0.2 mm; and / or the damping particles are one of iron powder particles, rubber particles, ceramic particles, and gravel particles.

[0017] In order to achieve the second purpose of the present invention, the present invention provides a compressor, including a crankshaft and a flange assembly, wherein the flange assembly is the above-mentioned flange assembly, and the annular rim disk portion of the flange disk of the flange assembly is sleeved on the crankshaft.

[0032] Flange assembly first embodiment:

[0033] See also Figures 1 to 8 This embodiment discloses a flange assembly 10 suitable for a compressor. Specifically, the compressor includes a crankshaft and the flange assembly 10 of this embodiment. The annular disk portion 111 of the flange 11 of the flange assembly 10 of this embodiment is sleeved on the crankshaft (not shown). Therefore, the flange assembly 10 of this embodiment includes a flange 11, and a cavity 13 is provided on the annular disk portion 111 of the flange 11. The cavity 13 is filled with a plurality of damping particles 14. The plurality of damping particles 14 can move in the cavity 13, indicating that there is still air in the cavity 13, and the plurality of damping particles 14 are not filled with a filling rate of 100%, so that the plurality of damping particles 14 can move in the cavity 13.

[0034] When the compressor is running and generates multi-body vibration, the vibration is transmitted to the flange 11 of the flange assembly 10 of this embodiment through the crankshaft. Since the cavity 13 on the annular disk portion 111 of the flange 11 is filled with a plurality of movable damping particles 14, when it is in low-frequency vibration, there is mainly friction movement between the plurality of damping particles 14 and between the plurality of damping particles 14 and the cavity wall of the cavity 13, while when it is in high-frequency vibration, there is mainly collision movement between the plurality of damping particles 14 and between the plurality of damping particles 14 and the cavity wall of the cavity 13. Therefore, along with the transmission of vibration, the plurality of damping particles 14 in the cavity 13 vibrate accordingly, so that the plurality of damping particles 14 continuously collide and rub with the cavity wall of the cavity 13, and at the same time, the plurality of damping particles 14 continuously collide and rub with each other, so as to convert the transmitted vibration energy into the kinetic energy of the damping particles 14, thereby greatly consuming and attenuating the vibration energy generated by the crankshaft, thereby reducing the vibration noise generated by the crankshaft. Furthermore, the cavity 13 on the annular disk portion 111 of the flange 11 of the flange assembly 10 of the present embodiment is filled with air and a plurality of movable damping particles 14, and the thermal conductivity of the damping particles 14 and the air are both lower than the thermal conductivity of the flange 11 body, so that the cavity 13 filled with air and a plurality of movable damping particles 14 can play a heat insulating role to prevent heat conduction from the exhaust chamber of the compressor to the intake chamber, thereby reducing the intake temperature rise of the compressor, increasing the intake volume of the compressor, and thereby improving the compression efficiency of the compressor.

[0035] Therefore, the flange assembly 10 of this embodiment can effectively attenuate the vibration energy and vibration noise generated by the crankshaft of the compressor as a whole, and can effectively prevent heat conduction, thereby improving work energy efficiency and work efficiency, and extending the service life and comfort of the compressor product.

[0036] In order to further increase the collision and friction area to increase the vibration energy consumption, the cavity 13 of this embodiment is arranged in an arc-shaped cavity extending in the circumferential direction of the annular rim disk portion 111, and the two ends of the cavity 13 in the circumferential direction of the annular rim disk portion 111 are rounded arc-shaped transitions, thereby maximizing the contact area between the damping particles 14 and the cavity wall of the cavity 13, further significantly and effectively attenuating the vibration energy and vibration noise.

[0037] In order to further attenuate vibration energy and vibration noise, the number of cavities 13 in this embodiment includes at least two, and each cavity 13 is filled with multiple damping particles 14 with the same or different filling rates, and multiple cavities 13 in this embodiment are arranged in the circumferential direction of the annular edge disk portion 111. Therefore, there is a ribbed portion (not marked) between two adjacent cavities 13 in the circumferential direction of the annular edge disk portion 111, and the ribbed portion will strengthen the overall structural rigidity of the flange 11, and multiple cavities 13 are arranged in the circumferential direction of the annular edge disk portion 111, and each cavity 13 is filled with multiple damping particles 14 with the same or different filling rates, which can effectively attenuate vibration energy and vibration noise at different positions and different frequency bands to a large extent.

[0038] Specifically, in this embodiment, the axial height of the cavity 13 of the annular rim disk portion 111 is equal to or less than 1 / 2 of the height of the annular rim disk portion 111, the radial width of the cavity 13 of the annular rim disk portion 111 is between 3 mm and 6 mm, and the central angle of the arc of the cavity 13 extending circumferentially of the annular rim disk portion 111 is equal to or less than 60°, thereby ensuring the vibration reduction effect.

[0039] Furthermore, in this embodiment, a certain proportion of movable damping particles 14 are filled in the cavity 13, thereby forming a particle damper. When the compressor vibrates, the damping particles 14 in the cavity 13 will be driven to move, and the movement of the damping particles 14 will greatly consume the vibration energy of each frequency band generated by the vibration source of the compressor. Preferably, the diameter of the damping particles 14 in this embodiment is between 0.01 mm and 0.2 mm, and the vibration reduction effect is better. Preferably, the filling rate of the multiple damping particles 14 filled in the cavity 13 of this embodiment is between 50% and 80%, because when the filling rate of the multiple damping particles 14 filled in the cavity 13 is too low, the vibration reduction effect is not prominent; when the filling rate of the multiple damping particles 14 filled in the cavity 13 is too large, the height of the cavity 13 in the axial direction of the annular rim disc portion 111 should not be too deep. Because in actual low-frequency working conditions, if the height of the cavity 13 in the axial direction of the annular rim disc portion 111 is too deep and the filling rate of the multiple damping particles 14 filled in the cavity 13 is too large, when the vibration energy is transmitted to the flange 11, only the upper damping particles 14 in the cavity 13 can participate in energy consumption, and the lower damping particles 14 in the cavity 13 are squeezed to varying degrees due to the gravity of the upper damping particles 14, so that the lower damping particles 14 in the cavity 13 present approximately solid characteristics, resulting in the lower damping particles 14 in the cavity 13 almost not participating in energy consumption. Therefore, in order to improve the vibration reduction energy consumption and vibration reduction effect, when the filling rate of the multiple damping particles 14 filled in the cavity 13 is too large, the height of the cavity 13 in the axial direction of the annular rim disc portion 111 should not be too deep, so as to increase the number of collisions and frictions of the damping particles 14 in the cavity 13, thereby ensuring the vibration reduction effect.

[0040] The damping particles 14 in this embodiment are one of iron powder particles, rubber particles, ceramic particles, and gravel particles. Preferably, gravel particles are used as the damping particles 14 and filled into the cavity 13, which is more economical.

[0041] In addition, the flange assembly 10 of the present embodiment further includes a silencer cover 12, and the outer end surface of the rim disc portion 111 in the axial direction is provided with a groove 112, and the silencer cover 12 is arranged on the outer end surface of the rim disc portion 111 and covers the groove 112 to form a cavity 13, and the cavity 13 is a closed cavity, so that it is easy to operate to fill the damping particles 14 into the cavity 13, thereby improving production efficiency. Specifically, the silencer cover 12 of the present embodiment is fastened to the rim disc portion 111 by screws.

[0042] In addition, the silencer cover 12 of this embodiment is provided with a silencer cavity 121 on the inner end surface adjacent to the annular rim disk portion 111, and the silencer cavity 121 is connected to the exhaust port 113 on the annular rim disk portion 111, thereby further attenuating the vibration energy and vibration noise generated by the crankshaft.

[0045] See also Fig. 9 and Fig.10 In this embodiment, the number of cavities 13 on the flange 11' includes at least two, each cavity 13 is filled with a plurality of damping particles 14 with the same or different filling rates, and the plurality of cavities 13 in this embodiment are arranged in the circumferential direction of the annular rim disk portion 111, and the plurality of cavities 13 in this embodiment are arranged in the radial direction of the annular rim disk portion 111, thereby consuming and attenuating the vibration energy generated by the crankshaft to a greater extent, thereby further reducing the vibration noise.

[0046] The third embodiment of the flange assembly:

[0047] As an explanation of the third embodiment of the flange assembly of the present invention, only the differences from the first embodiment of the flange assembly are explained below.

[0048] See also Fig.11 In this embodiment, the cross section of the cavity 13 on the flange 11" in the radial direction of the annular rim portion 111 is circular, thereby maximizing the contact area between the damping particles 14 and the cavity wall of the cavity 13, and further maximizing the effective attenuation of the vibration energy and vibration noise generated by the crankshaft.
