Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and particularly relates to a vibration damping device for a compressor, a compressor, a household appliance, and a control method for a household appliance. Background Art

[0002] There is a vibration damping device for a compressor, which includes a connecting member, a vibration absorbing housing, a bending piece, a particle damping box, and a temperature control component. The connecting member is fixedly connected to the top of the vibration absorbing housing, the vibration absorbing housing is supported on the base of the compressor, the connecting member supports the elbow pipe at the bottom of the liquid storage tank of the compressor, both ends of the bending piece are fixedly connected to the left and right side walls of the vibration absorbing housing, the bending piece is made of a shape memory alloy and the temperature of the bending piece can be controlled by the temperature control component to change its curvature; a translation groove is provided on the bending piece along its bending extension direction, and the particle damping box is hoisted on the bending piece through a connecting device and can translate along the translation groove. This vibration damping device consumes the vibration of the compressor through the back-and-forth vibration of the particle damping box to reduce the operating noise of the compressor, and adjusting the curvature of the shape memory alloy can change the vibration frequency of the particle damping box, and particles with different weights and different damping values will make the damping box have different damping values.

[0003] The problem with the existing such vibration damping device is that, in fact, during the use of household appliances, it is difficult for users to replace the damping particles by themselves and at any time, so the damping value cannot be adjusted at any time, and the vibration damping effect is poor. Summary of the Invention

[0004] The first object of the present invention is to provide a vibration damping device that can automatically adjust the damping value to improve the vibration damping effect.

[0005] The second object of the present invention is to provide a compressor that can automatically adjust the damping value to improve the vibration damping effect.

[0006] The third object of the present invention is to provide a household appliance that can automatically adjust the damping value to improve the vibration damping effect and enhance the user experience.

[0007] The fourth object of the present invention is to provide a control method for a household appliance that can automatically adjust the damping value.

[0008] The vibration damping device provided by the first object of the present invention includes a connecting member, a vibration absorption housing, and a damping mechanism. The connecting member is connected to the upper wall of the vibration absorption housing, and the damping mechanism is arranged in the space of the vibration absorption housing; the damping mechanism includes a driving module, a damping rod, a valve member, and a damping housing. The driving module drives the valve member to move; the damping housing is connected to the lower wall of the vibration absorption housing. The damping housing is provided with a damping chamber and a rod chamber. The damping chamber is used to accommodate damping liquid, and the damping rod is slidably arranged in the rod chamber and connected to the upper wall; the damping housing is provided with a first communication port, and the valve member is provided with a second communication port; the valve member is movably connected to the damping housing, and the first communication port communicates with the second communication port to enable the damping chamber to communicate with the rod chamber. The movement of the valve member can change the coincidence degree of the first communication port and the second communication port.

[0009] As can be seen from the above solution, when the driving module controls the movement of the valve member and changes the coincidence degree of the first communication port and the second communication port, the mating area between the damping liquid and the damping surface of the damping rod is changed, thereby changing the flow velocity of the damping liquid, so that the damping value changes when the damping rod vibrates up and down along the rod chamber. Therefore, during the actual operation of the compressor, according to the detected current operating frequency of the compressor, the driving module can be controlled to work to adjust the coincidence degree to the target coincidence degree that best matches the current operating frequency, so as to achieve a more ideal vibration damping effect.

[0010] A further solution is that the driving module drives the valve member to rotate, and the damping chamber is arranged on the outer periphery of the rod chamber.

[0011] As can be seen from the above, this setting is conducive to ensuring the sealing performance between the damping chamber and the rod chamber. In addition, compared with setting the valve member to move in a translational form, with the rotating valve member, the positions occupied by the driving module and the transmission mechanism are smaller. This setting is conducive to a compact structure and a small volume of the device. Especially when the space between the liquid storage tank and the compressor base is limited, this setting meets the requirements of a small volume design.

[0012] A further solution is that the damping mechanism further includes a driven gear and a rack that mesh with each other. The driving module drives the driven gear to rotate, and when the rack is driven, it translates in a straight line direction; the damping housing includes a damping spring piece, and the damping spring piece is connected between the upper wall and the lower wall. The rack is connected to the damping spring piece, and the curvature of the damping spring piece can be changed when the rack translates.

[0013] As can be seen from the above, in this setting, after the driving module drives the rack to rotate through the driven gear, the curvature of the damping spring piece is changed when the rack translates, thereby changing the vibration frequency of the vibration damping device. In this setting, according to the detected current operating frequency of the compressor, the driving module can be controlled to work to adjust the vibration frequency of the vibration damping device to the optimal vibration frequency to solve the vibration at the current operating frequency, thereby improving the vibration damping effect.

[0014] A further solution is that the valve member includes a gear portion; the damping mechanism further includes a driving gear, the driving module drives the driving gear to rotate, and the driving gear meshes with the gear portion.

[0015] A further solution is that the gear portion serves as a driven gear.

[0016] As can be seen from the above, in this setting, the driving module only needs to use one motor. After the motor drives the driving gear to rotate, during the rotation of the valve member, not only can the coincidence degree between the first communication port and the second communication port be changed, but also the rack is driven to translate to change the curvature of the damping spring plate. Therefore, the damping value and the damping frequency of the device are adjusted simultaneously. Since the amount and type of the damping liquid in the damping cavity can be configured according to the operating data of the compressor before leaving the factory, and the damping change caused by the above-mentioned change in the coincidence degree and the damping frequency change caused by the change in the curvature of the damping spring plate both conform to the linear law, it is possible to configure the correct damping liquid to make the adjustment results of the damping value and the damping frequency meet the damping requirements of the compressor during adjustment.

[0017] Another further solution is that the damping spring plate is convexly arranged.

[0018] As can be seen from the above, since a damping mechanism with a certain volume needs to be arranged inside the damping housing, if the spring plate is concave, the maximum curvature of the damping spring plate is limited. In this setting, the adjustable range of the curvature of the damping spring plate is larger, which can better meet the adjustment range requirements of the damping frequency.

[0019] Another further solution is that two damping spring plates are arranged on opposite sides of the damping housing, the number of racks is two, the two racks are respectively connected to the two damping spring plates, and the two racks are driven by the same driven gear.

[0020] As can be seen from the above, in this setting, the damping housing has symmetry, so it has better structural stability and can also bring better damping effect. And, in this setting, it is still not necessary to add an additional motor for adjusting the curvature of the second damping spring plate, and the adjustment and control of the two damping spring plates can still be completed without increasing the input of the power source.

[0021] A further solution is that the damping mechanism further includes a limiting member, the limiting member includes a base portion and two limiting portions protruding from opposite sides of the base portion; the base portion is sleeved on the damping rod, both racks are located between the two limiting portions, and the limiting portions limit the racks in the direction perpendicular to the straight line direction and perpendicular to the damping rod.

[0022] As can be seen from the above, by virtue of the characteristics of the two racks being parallel and opposite to each other, only one part is needed to limit the two racks, ensuring the straightness of the rack movement and ensuring the stability and reliability of the rack.

[0023] Another further solution is that the damping housing includes a first peripheral wall, and a plurality of first communication ports arranged along the circumferential direction of the first peripheral wall are provided on the first peripheral wall; the valve member includes a second peripheral wall, and the second peripheral wall includes a plurality of second communication ports arranged along the circumferential direction of the second peripheral wall; the first peripheral wall and the second peripheral wall are sleeved together.

[0024] As can be seen from the above, in this setting, the damping liquid can be more evenly damped with each position in the circumferential direction of the damping part of the damping rod, the mechanical state of the damping rod is more stable, and the vibration reduction effect is better.

[0025] The compressor provided by the second object of the present invention includes a base, a liquid storage tank connecting pipe, and a vibration reduction device; the vibration reduction device adopts the above-mentioned vibration reduction device; the vibration reduction device is arranged between the base and the liquid storage tank connecting pipe, the lower wall is connected to the base, and the connecting member is connected to the liquid storage tank connecting pipe.

[0026] As can be seen from the above solution, when the driving module controls the movement of the valve member and changes the coincidence degree between the first communication port and the second communication port, the matching area between the damping liquid and the damping surface of the damping rod is changed, thereby changing the flow velocity of the damping liquid, so as to change the damping value when the damping rod vibrates up and down along the rod cavity. Therefore, during the actual operation of the compressor, according to the detected current operating frequency of the compressor, the driving module can be controlled to adjust the coincidence degree to the target coincidence degree that best matches the current operating frequency, so as to achieve a more ideal vibration reduction effect.

[0027] The household appliance provided by the third object of the present invention includes a compressor, and the compressor adopts the above-mentioned compressor.

[0028] The control method of the household appliance provided by the fourth object of the present invention adopts the above-mentioned household appliance; the control method includes obtaining the operating frequency of the compressor; obtaining the target angle corresponding to the operating frequency; controlling the driving module to rotate the valve member to the target angle.

[0029] As can be seen from the above solution, during the actual operation of the compressor, the control system of the household appliance can, according to the detected current operating frequency of the compressor, control the driving module to adjust the coincidence degree to the target coincidence degree that best matches the current operating frequency, so as to achieve a more ideal vibration reduction effect. Moreover, this adjustment process is automatically judged and executed, without the need for user instruction control, let alone stopping the machine for manual operation, greatly improving the user experience.

[0037] Compressor and shock absorption device embodiments Refer to Figure 1 , for home appliances such as air conditioners and refrigerators of the present invention, the home appliance includes the compressor of this embodiment. The compressor includes a main body 91, a liquid storage tank 92, a liquid storage tank connecting pipe 93, and a base 94. The main body 91 is a vertical machine. The liquid storage tank 92 is adjacent to the main body 91. The liquid storage tank connecting pipe 93 extends horizontally from the lower part of the outer periphery of the main body 91 and then bends upward and is connected to the lower end of the liquid storage tank 92. The compressor further includes the shock absorption device 1 of this embodiment. The shock absorption device 1 is arranged directly below the liquid storage tank 92 and is located between the liquid storage tank connecting pipe 93 and the base 94.

[0038] Refer to Figure 2 and Figure 3 , in the coordinate system in the figure, both the x-axis direction and the y-axis direction represent the horizontal direction, and the z-axis direction represents the vertical direction. Among them, the x-axis direction represents the linear direction of the rack translation in the present invention, the y-axis direction represents the direction of the rack limit of the limiting part, and the z-axis direction represents the translation direction of the damping rod in the rod cavity.

[0039] The shock absorption device 1 includes a shock absorption housing 2, a connecting member 3, and a damping mechanism 4. The shock absorption housing 2 includes an upper wall 21, a lower wall 22, and two shock absorption spring sheets 23. In this embodiment, both the upper wall 21 and the lower wall 22 are square wall plates, and the upper wall 21 is arranged directly above the lower wall 22; the two are symmetrically arranged on the opposite sides in the x-axis direction, and the upper and lower edges of each shock absorption spring sheet 23 are fixedly connected to the edge of the upper wall 21 and the edge of the lower wall 22 respectively. A space 200 is formed between the upper wall 21, the lower wall 22, and the two shock absorption spring sheets 23. Among them, the shock absorption spring sheet 23 is a bent spring sheet. In this embodiment, the middle parts of the two shock absorption spring sheets 23 are bent and protrude outward towards the outer periphery of the damping housing 41.

[0040] Refer to Figures 1 to 3, the connecting member 3 is fixedly connected to the upper side of the upper wall 21. The connecting member 3 includes a support column 32 erected from the upper surface of the upper wall 21 and a supporting portion 31 connected to the upper end of the support column 32. A concave position 310 conforming to the shape of the liquid storage tank connecting pipe 93 is formed on the upper surface of the supporting portion 32. When assembling the damping device 1, the lower wall 22 is fixed to the base 94 by existing fixed connection methods such as welding or bolt connection. The liquid storage tank connecting pipe 93 is placed into the concave position 310, and then the supporting portion 32 is welded to the liquid storage tank connecting pipe 93.

[0041] See Figures 2 to 4 , the damping mechanism 4 is arranged in the space 200. The damping mechanism 4 includes a damping housing 41, a damping rod 42, two racks 43, a limiting member 44, a valve member 45, a driving gear 48 and a driving module 49.

[0042] The outer contour of the damping housing 41 is annular. The damping housing 41 includes a bottom shell 418 and a face cover 419 covering the upper side opening of the bottom shell 418 vertically. An annular damping chamber 400 is formed in the bottom shell 418. The damping chamber 400 is used to accommodate damping liquid, and the damping liquid can be materials with good stability such as silicone oil, mineral oil, synthetic oil, etc.; the damping housing 41 includes a first peripheral wall 411 on the inner periphery of the damping chamber 400. A rod chamber 410 is formed on the inner periphery of the first peripheral wall 411. The rod chamber 410 is located at the center of the damping housing 41. Among them, before assembly, the first peripheral wall 411 can be an independent structure separated from the bottom shell 418, and the first peripheral wall 411 is fixedly connected to the bottom shell 418 after the damping rod 42 is installed in the rod chamber 410; the bottom shell 418 further includes a top wall 413. The top wall 413 is connected to the upper edge of the first peripheral wall 411 and shields the rod chamber 410 from above. A first through hole 414 communicating with the rod chamber 410 vertically is provided on the top wall 413. In addition, a plurality of first communication ports 412 are uniformly arranged along the circumferential direction of the first peripheral wall 411. The first communication ports 412 communicate between the damping chamber 400 and the rod chamber 410. The first communication ports 412 extend from the bottom to the top of the first peripheral wall 411 and stop at the starting point of the top wall 413.

[0043] The damping rod 42 includes a rod portion 421 and a damping portion 422. The damping portion 422 is connected to the lower end of the rod portion 421. The damping portion 422 is a retaining ring structure with an outer diameter larger than that of the rod portion 421.

[0044] The limiting member 44 includes a base portion 441 extending horizontally and two limiting portions 442 protruding downward from the opposite sides of the base portion 441 in the y-axis direction. A second through hole 440 is provided on the base portion 441.

[0045] The valve member 45 is of a cylindrical structure, and the center of the valve member 45 penetrates vertically. The valve member 45 includes a gear portion 452 and a second peripheral wall 451 arranged in sequence from top to bottom. The gear portion 452 is a toothed ring structure with outer peripheral teeth. A plurality of second communication ports 450 are arranged on the second peripheral wall 451 at equal intervals along its circumferential direction. The number of the second communication ports 450 is the same as that of the first communication ports 412. Further, in this embodiment, in addition to communicating between the inner and outer sides of the second peripheral wall 451, the second communication ports 450 also open at the bottom of the second peripheral wall 451. In this embodiment, the gear portion 452 is the driven gear of the present invention.

[0046] In this embodiment, the drive module 49 includes only one motor, and the driving gear 48 is connected to the output shaft of the motor.

[0047] See Figures 2 to 5 , the damping rod 42 is placed in the rod cavity 410, the damping portion 422 is located in the rod cavity 410, and the rod portion 421 extends out of the top wall 413 through the first through hole 414. The damping rod 42 can move up and down vertically in the rod cavity 410; the second peripheral wall 451 of the valve member 45 passes through the central hole 4910 of the face cover 419 downward and is sleeved on the outer periphery of the first peripheral wall 411, that is, the valve member 45 is movably connected to the damping housing 41.

[0048] Combined with Figure 6 and Figure 7 , at this time, the first communication port 412 communicates with the second communication port 450 to enable the damping cavity 400 to communicate with the rod cavity 410, and at this time, the valve member 45 can rotate around the center of the damping housing 41, and the coincidence degree of the first communication port 412 and the second communication port 450 can be changed during the rotation. Among them, the coincidence degree of the first communication port 412 and the second communication port 450 can be related to the coincidence angle of the first communication port 412 and the second communication port 450. As Figure 6 shown, the coincidence degree of the first communication port 412 and the second communication port 450 is the largest, and the coincidence angle is a at this time; as Figure 7 shown, after the valve member 45 rotates around the center of the damping housing 41, the coincidence degree of the first communication port 412 and the second communication port 450 decreases, and the coincidence angle is b at this time, and the angle b is smaller than the angle a. Of course, the coincidence degree can also be related to the coincidence area of the first communication port 412 and the second communication port 450.

[0049] Particularly see Figure 2 and Figure 3 , the drive module 49 is fixedly installed on the upper side of the face cover, and the driving gear 48 is located on the outer periphery of the gear portion 452 and meshes with the gear portion 452.

[0050] Continue to see Figures 2 to 5, two racks 43 are symmetrically arranged about the above-mentioned center of the circle and both extend along the y-axis direction. Both racks 43 are engaged with the gear part 452; the base 441 of the limiting member 44 is sleeved on the damping rod 42, that is, the damping rod 42 passes through the second through hole 440. Both racks 43 are located between the two limiting parts 442, and the two limiting parts 442 on both sides limit the two racks 43 in the y-axis direction. In this setting, when the valve member 45 rotates, both racks 43 can only move along the y-axis direction. The extending ends of the two racks 43, which are far from the above-mentioned center of the circle, are respectively fixedly connected to the inner wall surfaces of the two damping spring pieces 23. When the rack 43 translates, the curvature of the damping spring piece 23 can be changed.

[0051] Primarily, when the vibration device of the present invention works, when the driving module 49 controls the movement of the valve member 45 and changes the coincidence degree between the first communication port 412 and the second communication port 450, the matching area of the damping liquid and the damping surface of the damping rod 42 is changed, so as to change the flow rate of the damping liquid, so that the damping value changes when the damping rod 42 vibrates up and down along the rod cavity 410. Therefore, during the actual operation of the compressor, according to the detected current operating frequency of the compressor, the driving module 49 can be controlled to work to adjust the coincidence degree to the target coincidence degree that best matches the current operating frequency, so as to achieve a more ideal vibration damping effect.

[0052] Further, in this embodiment, the driving module 49 only needs to adopt a single motor. After the motor drives the driving gear 48 to rotate, during the rotation of the valve member 45, not only can the coincidence degree between the first communication port 412 and the second communication port 450 be changed, but also the rack 43 is driven to translate to change the curvature of the damping spring piece 23. Therefore, the damping value and the vibration damping frequency of the device are adjusted simultaneously. By configuring the correct damping liquid, the adjustment results of the damping value and the vibration damping frequency can meet the vibration damping requirements of the compressor during adjustment.

[0053] In other embodiments, the valve member can be a translating valve plate. The driving module includes a motor, the motor drives a transmission gear to rotate, the transmission gear drives a transmission rack to translate and the valve member to translate. In this setting, in the damping housing, the damping chamber, the valve groove and the rod cavity are arranged along the horizontal first direction, and the valve plate can translate in the valve groove along the horizontal second direction.

[0054] In other embodiments, the driving module includes a first motor and a second motor, and the driven gear is another gear other than the gear part of the valve member. The first motor, the driving gear and the gear part are sequentially transmitted; the second motor, another driving gear, the driven gear and the rack are sequentially transmitted, or the second motor, the driven gear and the rack are sequentially transmitted. In this setting method, the coincidence degree and the curvature can be adjusted separately.

[0055] Embodiment of the control method of household appliances The control method of the household appliance in this embodiment adopts the household appliance in the previous embodiment. The control method includes: After receiving the startup instruction sent by the user, the system module drives the valve member to rotate to the target angle corresponding to the startup process. Among them, the optimal angle corresponding to the startup process and the optimal angles corresponding to other operating states of the compressor can obtain the corresponding vibration frequency and damping value during the vibration test of the compressor. By adjusting the valve member to different angles, it can be corresponding during the startup process of the compressor and at different compressor operating frequencies, so as to determine the optimal angles corresponding to the startup process, shutdown process and other operating processes, and use the optimal angle value as the target angle corresponding to this operating state.

[0056] After the compressor operates stably, obtain the operating frequency of the variable-frequency compressor, obtain the optimal angle corresponding to the current operating frequency from the pre-stored data, and use this optimal angle as the target angle. Subsequently, control the drive module to work so that the valve member rotates to this target angle.

[0057] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
