[0002] As the outdoor unit of the air conditioner develops towards miniaturization and lightness, it is becoming increasingly difficult to solve the noise and vibration problems of the compressor during the development stage. At present, the compressors of outdoor units are basically variable frequency compressors. Since the liquid storage tank is connected to the side wall of the tank of the compressor, and the inertia force and inertia moment of the rotating parts inside the variable frequency compressor are constantly changing under the suction and exhaust pressure, the compressor is always vibrating eccentrically. In order to reduce vibration and noise, three rubber pads are usually set between the compressor base and the chassis to reduce the vibration of the compressor. However, after the rubber pad is set, its natural frequency is fixed, and it is impossible to achieve wide-band and effective vibration and noise reduction, which causes the compressor to vibrate and make loud noise in certain frequency bands or during the start-up and shutdown process. Summary of the invention

[0003] Therefore, the present invention provides a vibration absorbing device, which can solve the technical problem that a rubber foot pad is set between the compressor base and the chassis to reduce the vibration of the compressor.

[0011] In some embodiments, the elastic member has an initial state, a first deformation state, and a second deformation state; when the elastic member is in the initial state, the vibration absorption frequency of the vibration absorption device is the same as the frequency of the compressor when it vibrates the most during the startup process; when the elastic member is in the first deformation state, the vibration absorption frequency of the vibration absorption device is the same as the operating frequency of the compressor in the stable operation stage; when the elastic member is in the second deformation state, the vibration absorption frequency of the vibration absorption device is the same as the frequency of the compressor when it vibrates the most during the shutdown process.

[0012] In some embodiments, the elastic member extends in the housing along the circumferential direction of the compressor shell, and the driving component can drive the elastic member to deform along the circumferential direction of the compressor shell.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0037] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0038] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0039] See also Figures 1 to 9 As shown, according to an embodiment of the present invention, a compressor is provided, including a driving component 1, an elastic component, a vibration absorbing component 3 and a shell 5, the driving component 1, the elastic component and the vibration absorbing component 3 are all arranged in the shell 5, one end of the elastic component is connected to the driving component 1, the other end of the elastic component is fixed on the shell 5, and the vibration absorbing component 3 is arranged on the elastic component.

[0040] In this technical solution, since one end of the elastic member is connected to the driving component 1 and the other end of the elastic member is fixed to the housing 5, when the driving component 1 is working, it can drive the elastic member to deform, thereby changing the effective vibration absorption frequency of the vibration absorption device, and widening the effective vibration absorption range of the vibration absorption device. When the vibration absorption device of the present application is installed on the compressor housing 13, because the effective vibration absorption frequency of the vibration absorption device can change, when the vibration generated by the compressor during operation is transmitted to the vibration absorption device, the vibration absorption component 3 and the elastic member of the vibration absorption device can consume the vibration of the compressor in different frequency bands during the vibration process, thereby achieving broadband and effective vibration reduction and noise reduction, thereby solving the problem of vibration and high noise of the compressor in certain frequency bands or during the start-up and shutdown process.

[0041] It is understandable that the vibration amplitude of the vibration absorbing component 3 is relatively large, so in terms of consuming the vibration of the compressor, the vibration absorbing component 3 plays a major role compared to the elastic component. Preferably, the vibration absorbing component 3 is suspended, which makes it easier for the vibration absorbing component 3 to be driven to vibrate, so that the vibration can be better absorbed. Among them, the material of the elastic member can be stainless steel, nickel alloy or titanium alloy, etc. Stainless steel has good corrosion resistance and elasticity, and is suitable for environments requiring high corrosion resistance; nickel alloys: such as Monel and Inconel, have excellent corrosion resistance and high temperature performance, and are suitable for springs in extreme environments; titanium alloys: such as Grade5Ti-6Al-4V, have extremely high strength and corrosion resistance, and are excellent materials for making elastic parts, but the cost is higher than the first two.

[0042] See also Figures 1 to 3 As shown, the elastic member includes a first elastic segment 2 and a second elastic segment 4, one end of the first elastic segment 2 is connected to the driving component 1, the other end of the first elastic segment 2 is connected to the vibration absorbing component 3, one end of the second elastic segment 4 is connected to the vibration absorbing component 3, and the other end of the second elastic segment 4 is fixed on the shell 5.

[0043] In this embodiment, when the elastic member is divided into two elastic segments and connected to the vibration absorbing component 3, under the same vibration, the vibration absorbing component 3 swings back and forth with a larger amplitude, and the vibration absorbing component 3 can more easily consume the vibration generated by the compressor during the vibration process.

[0044] It should be noted that when the elastic member includes two shrapnel segments, the number of shrapnel segments and the vibration absorbing component 3 can be multiple, and each shrapnel segment and the vibration absorbing component 3 are arranged alternately, one end of the first shrapnel segment is connected to the driving component 1, and one end of the tail shrapnel segment is fixed on the housing 5. Of course, two shrapnel segments plus one vibration absorbing component 3 can also be arranged in multiple rows, and the driving component 1 is simultaneously connected to one end of the first shrapnel segment 2 in each row.

[0045] See also Figure 4As shown, the vibration absorbing component 3 has a cavity, and a plurality of damping particles 6 are filled in the cavity. By filling a plurality of damping particles 6 in the vibration absorbing component 3, when the vibration absorbing component 3 is driven to vibrate, the friction and collision between the damping particles 6 can further consume the vibration energy of the compressor, thereby achieving a better vibration absorbing effect. It can be understood that by setting damping particles 6 of different masses and types, the purpose of variable mass and damping of the device can be achieved. The damping particles 6 can be rubber particles, epoxy resin particles, metal particles, magnetic particles, etc. The rubber particles can be made of natural rubber or synthetic rubber (such as styrene-butadiene rubber, chloroprene rubber, silicone rubber, etc.); although the epoxy resin itself has a high hardness, it can also be made into particles with good damping performance by adjusting the formula and combining it with rubber powder or microspheres; the metal particles can be particles made of copper, aluminum or stainless steel, etc.; the magnetic particles can be particles made of iron powder, nickel powder, etc. Among them, the vibration absorbing component 3 can be composed of a bottle body and a lid, and each damping particle 6 is loaded into the bottle body, and then the bottle mouth is sealed with the lid.

[0046] See also Figure 2 and Figure 4 As shown, a battery and a magnetic component 7 are also provided in the shell 5, a conductive component 8 is provided on the vibration absorbing component 3, the conductive component 8 is connected to the battery through a first wire 9 to form a first electrical connection circuit, and the battery is connected to the driving component 1 through a second wire to form a second electrical connection circuit.

[0047] In this embodiment, the magnetic component 7 can generate a magnetic field in the shell 5. Since the conductive component 8 is on the vibration absorbing component 3, when the vibration absorbing component 3 is driven to vibrate, the conductive component 8 will be driven to cut the magnetic field, so that it can generate electricity autonomously and store it in the battery for the driving component 1 to be used when it is running, and finally achieve the purpose of self-powering the entire vibration absorbing device. Among them, the conductive component 8 can be a wound multi-turn coil, and the multi-turn coil is sleeved on the vibration absorbing component 3. The magnetic component 7 can be a permanent magnet and the number is two. The two permanent magnets are respectively fixed on the top wall 55 and the bottom wall 56 of the shell 5. The conductive component 8 on the vibration absorbing component 3 is located between the two permanent magnets. The two permanent magnets can strengthen the magnetic field strength and increase the power generation. Among them, the battery can be fixed on the driving component 1.

[0048] See also Figure 1 and Figure 2 As shown, a gear 10 and a tooth track 11 are further provided in the housing 5 , the driving component 1 is a motor, the gear 10 is mounted on the output shaft of the motor, and the gear 10 is meshed with the tooth track 11 .

[0049] In this technical solution, during the operation of the motor, the motor will drive the gear 10 to rotate. Since the gear 10 is meshed with the tooth track 11, during the rotation of the gear 10, the gear 10 will move along the tooth track 11, so that the motor will also move. Because the motor is connected to the elastic member, the motor will squeeze the elastic member during the movement and cause the elastic member to deform, and finally the vibration absorption frequency of the vibration absorption device will change. That is, the present application realizes that the motor can drive the elastic member to deform by installing the gear 10 on the output shaft of the motor and the gear 10 is meshed with the tooth track 11. Since the motor can be designed to be very small, the use of the motor as the driving component 1 is conducive to the miniaturization of the vibration absorption device. In addition, the driving component 1 can also be a cylinder or a hydraulic cylinder, and the telescopic end of the cylinder or the hydraulic cylinder is connected to the elastic member. When the cylinder or the hydraulic cylinder is telescopic, the purpose of deforming the elastic member can also be achieved.

[0050] See also Figures 1 to 3 As shown, a guide component 12 is further provided in the housing 5 . The extending direction of the guide component 12 is the same as the extending direction of the tooth track 11 . The guide component 12 is used to guide the motor during movement.

[0051] In this embodiment, the guide component 12 is provided so that the motor can move along a predetermined track when the elastic member is deformed during the movement, thereby making the motor more stable during the movement. The guide component 12 can be a guide rod, and the two ends of the guide rod are respectively fixed on the left side wall 51 and the right side wall 52 of the housing 5. The guide rod passes through the motor, and the motor can move along the guide rod. The guide component 12 is in a suspended state in the housing 5.

[0052] The present invention also provides a compressor, comprising the aforementioned vibration absorbing device and a compressor housing 13, wherein the vibration absorbing device is mounted on the compressor housing 13. Since the effective vibration absorbing frequency of the vibration absorbing device can be changed, the vibration absorbing device can absorb vibrations of the compressor in different frequency bands. The compressor of the present application particularly refers to a variable frequency compressor.

[0053] As a specific implementation, the elastic member has an initial state, a first deformation state, and a second deformation state; when the elastic member is in the initial state, the vibration absorption frequency of the vibration absorption device is the same as the frequency of the compressor when it vibrates the most during the startup process; when the elastic member is in the first deformation state, the vibration absorption frequency of the vibration absorption device is the same as the operating frequency of the compressor in the stable operation stage; when the elastic member is in the second deformation state, the vibration absorption frequency of the vibration absorption device is the same as the frequency of the compressor when it vibrates the most during the shutdown process.

[0054] In this technical solution, the frequency of the compressor when the vibration is the largest during the startup process and the frequency of the compressor when the vibration is the largest during the shutdown process are both lower than the working frequency of the compressor after stable operation, while the frequency of the compressor when the vibration is the largest during the startup process and the frequency of the compressor when the vibration is the largest during the shutdown process are relatively close. The elastic member can be designed to make the vibration absorption frequency of the vibration absorption device the same as the frequency of the compressor when the vibration is the largest during the startup process in the initial state. When the compressor is in the startup stage, the driving component 1 does not need to work, and the vibration absorption frequency of the vibration absorption device is the same as the frequency of the compressor when the vibration is the largest during the startup process, so that the vibration absorption device achieves the best vibration absorption effect during the startup stage of the compressor. Among them, the initial state of the elastic member can be that the elastic member is in a natural state, or the driving component 1 squeezes the elastic member in advance to make the elastic member in an initial deformation state. When the compressor is in the stable operation stage, the working frequency increases, and it is necessary to control the driving component 1 to run for a first preset time to drive the elastic member to switch to the first deformation state, so that the vibration absorption frequency of the vibration absorption device is the same as the working frequency of the compressor in the stable operation stage, and finally the vibration absorption device achieves the best vibration absorption effect during the stable operation stage of the compressor. When the compressor is in the shutdown stage, the operating frequency decreases, and it is necessary to control the driving component 1 to run for a second preset time to drive the elastic member to switch to the second deformation state, so that the vibration absorption frequency of the vibration absorption device is the same as the frequency when the compressor vibrates the most during the shutdown process, and finally the vibration absorption device achieves the best vibration absorption effect during the shutdown stage of the compressor.

[0055] See also Figure 1 and Figure 5 As shown, the housing 5 further includes an inner arc wall 53 and an outer arc wall 54, the inner arc wall 53 is attached to the housing of the compressor housing 13, and the inner arc wall 53 and the outer arc wall 54 both extend along the circumference of the compressor housing 13. In the embodiment, when the inner arc wall 53 and the outer arc wall 54 of the housing 5 both extend along the circumference of the compressor housing 13, it indicates that the vibration absorbing device as a whole extends along the circumference of the compressor housing 13. Since the vibration generated by the compressor is mainly transmitted along the circumference of the compressor housing 13, when the vibration absorbing device as a whole extends along the circumference of the compressor housing 13, the vibration generated by the compressor can be better transmitted to the vibration absorbing device. Further, the elastic member extends along the circumference of the compressor housing 13 in the housing 5, and the driving component 1 can drive the elastic member to deform along the circumference of the compressor housing 13, so that the vibration absorbing device can better absorb the vibration generated by the compressor. It should also be noted that the tooth track 11 is fixed on the inner arc wall 53, and the tooth track 11 and the guide component 12 are also arc-shaped.

[0056] See also Figure 5 and Figure 6As shown, the compressor also includes a liquid storage tank 14, and the liquid storage tank 14 and the vibration absorbing device are respectively installed on both sides of the compressor housing 13, and the center of mass of the compressor coincides with the center of the compressor housing 13. In this technical solution, the weight of the liquid storage tank 14 and the center of mass position of the compressor are first obtained, and then the weight of the vibration absorbing device of the present application is designed according to the correspondence between the weight of the liquid storage tank 14 and the center of mass position of the compressor, and finally the designed vibration absorbing device is fixed on the compressor housing 13, and the vibration absorbing device and the liquid storage tank 14 are respectively located on the left and right sides of the compressor housing 13 to achieve the coincidence of the center of mass of the entire compressor and the center of the compressor housing 13. That is, the present application balances the eccentricity of the compressor caused by the liquid storage tank 14 by setting a vibration absorbing device, so that the compressor is more stable during operation. Among them, the center of the compressor housing 13 is the geometric center of the compressor housing 13. Figure 7 The design flow chart of the compressor of the embodiment of the present invention is shown in FIG. Figure 7 In the figure, the compressor cylinder structure is the compressor housing 13 of the present application.

[0057] The present invention also provides a compressor control method for controlling the operation of the above-mentioned compressor, the control method comprising:

[0058] The frequency at which the compressor vibrates the most during startup is obtained, the operating frequency of the compressor after stable operation is obtained, and the frequency at which the compressor vibrates the most during shutdown is obtained.

[0059] When the compressor is in the startup stage, the elastic member is in the initial state, and the vibration absorption frequency of the vibration absorption device is the same as the frequency of the maximum vibration of the compressor during the startup process, so that the vibration absorption device achieves the best vibration absorption effect during the startup stage of the compressor.

[0060] When the compressor is in a stable operation stage, the driving component 1 is controlled to run for a first preset time to drive the elastic member to switch to a first deformation state, so that the vibration absorption frequency of the vibration absorption device is the same as the working frequency of the compressor in the stable operation stage, and finally the vibration absorption device achieves the best vibration absorption effect in the stable operation stage of the compressor.

[0061] When the compressor is in the shutdown stage, the driving component 1 is controlled to run for a second preset time to drive the elastic member to switch to the second deformation state, so that the vibration absorption frequency of the vibration absorption device is the same as the frequency when the compressor vibrates the maximum during the shutdown process, and finally the vibration absorption device achieves the best vibration absorption effect during the shutdown stage of the compressor.

[0062] Among them, the frequency of the compressor when the vibration is the largest during the startup process and the frequency of the compressor when the vibration is the largest during the shutdown process need to be obtained in advance through testing, while the operating frequency of the compressor after stable operation does not need to be obtained through testing in advance and can be directly displayed. It can be understood that after the compressor is shut down, the driving component 1 drives the elastic member to switch to the initial state.

[0063] Finally, it should be noted that Fig. 9 The control flow chart of the compressor in the working process of the embodiment of the present invention is shown. Fig. 9 In the embodiment, adjusting the stiffness of the elastic member is to adjust the deformation degree of the elastic member, the mass block is the vibration absorbing component 3, and the vibration frequency of the mass block represents the vibration absorbing frequency of the vibration absorbing device.
