Description

Technical Field

[0001] The invention belongs to the technical field of compressors, and in particular relates to a foot pad structure and a compressor. Background Art

[0002] Rotary compressors are widely used in the field of air conditioning due to their simple structure and low cost. Rotary compressors are generally composed of a main cylinder, a liquid storage tank, a base and a rubber foot pad. Due to the presence of the liquid storage tank, the center of gravity of the compressor is not at the geometric center of the main cylinder; and the installation of the existing compressor base is too simple, evenly distributed around the main cylinder in the horizontal plane, and the vertical height is also the same, without fully considering the different forces on the vibration-damping rubber foot pads at the bottom of the actual compressor base. This causes the compressor to be in a tilted state all the time, and the vibration energy is not evenly attenuated by the rubber foot pad, which can easily lead to abnormal vibration and noise. In addition, the vibration reduction effect of the compressor foot pad is limited by the material and structural form of the foot pad, and cannot meet the vibration reduction requirements under various working conditions.

[0003] Since the compressor foot pads in the prior art cannot meet the vibration reduction requirements under various working conditions, resulting in technical problems such as high compressor noise and poor user experience, the present invention studies and designs a foot pad structure and a compressor. Summary of the invention

[0004] Therefore, the present invention provides a foot pad structure and a compressor, which can solve the technical problem in the prior art that the compressor foot pad cannot meet the vibration reduction requirements under various working conditions, resulting in high compressor noise.

[0005] In order to solve the above-mentioned problem, the present invention provides a foot pad structure, including: a main body, a plurality of first chambers are arranged in the main body, and the plurality of first chambers are arranged in sequence along the circumference of the main body; a balancing component is provided on the main body, and the balancing component is used to determine whether the force on the main body is balanced, and, according to the judgment result of the balancing component, one or more of the plurality of first chambers can perform air pressure adjustment.

[0006] In some embodiments, a pump body is disposed in the main body, and a plurality of the first chambers are arranged in sequence around the outer peripheral wall of the pump body. The pump body is connected to the first chambers, and an exhaust pipe and an intake pipe are disposed on the pump body. The exhaust pipe is used to discharge the gas in the first chamber out of the main body, and the intake pipe is used to guide the gas outside the main body into the pump body.

[0007] In some embodiments, the foot pad structure includes a first partition, and two adjacent first chambers are separated by the first partition.

[0008] In some embodiments, the balancing assembly includes a balancing chamber, the balancing chamber is located in the main body, a sphere is disposed at the center of the balancing chamber, and a plurality of the first chambers are sequentially arranged along the circumference of the balancing chamber.

[0009] In some embodiments, a plurality of second partitions are provided in the balance chamber, and the second partitions are arranged at intervals along the circumference of the balance chamber. The second partitions divide the balance chamber into a plurality of second chambers, and the sphere can move into any of the second chambers according to the force conditions of the main body.

[0010] In some embodiments, the first chamber and the second chamber are arranged in a one-to-one correspondence.

[0011] In some embodiments, a groove is provided on the main body, and the groove is used to install the compressor. The center of the groove, the center of the balance chamber, and the center of the sphere are all located on the same center line of the main body.

[0013] The present invention also provides a compressor, which comprises the aforementioned foot pad structure.

[0014] The foot pad structure and compressor provided by the present invention have the following beneficial effects:

[0015] When the compressor is installed on the main body, the balancing component is used to determine whether the force on the main body is balanced, thereby determining whether the compressor is in a balanced state. Since the first chambers are arranged in sequence along the circumference of the main body, when the compressor is not in a balanced state, the air pressure in the first chambers at the corresponding positions is adjusted by adjusting the air pressure in the first chambers at various positions in the main body, so that the compressor remains balanced. The main body adopts vibration-damping materials, thereby effectively reducing the vibration of the compressor, reducing the noise of the compressor, and achieving better vibration-damping effects under different working conditions.

[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 Figure 1-16 As shown, according to an embodiment of the present invention, a foot pad structure is provided, comprising: a main body 1, a plurality of first chambers 2 are arranged in sequence along the circumference of the main body 1, a balancing component 5 is arranged on the main body 1, and the balancing component 5 is used to determine whether the force on the main body 1 is balanced, and, according to the determination result of the balancing component 5, one or more of the plurality of first chambers 2 can adjust the air pressure. In this technical solution, when the compressor is installed on the main body 1, the balancing component 5 is used to determine whether the force on the main body 1 is balanced, thereby determining whether the compressor is in a balanced state. Since the first chambers 2 are arranged in sequence along the circumference of the main body 1, when the compressor is not in a balanced state, the air pressure in the first chamber 2 at the corresponding position is adjusted by adjusting the air pressure in the first chamber 2 at each position in the main body 1, so that the compressor is kept balanced. The main body 1 adopts a vibration reduction material, thereby effectively reducing the vibration of the compressor, reducing the noise of the compressor, and achieving a good vibration reduction effect under different working conditions. The first chamber 2 is a closed chamber.

[0040] In some embodiments, a pump body 3 is disposed in the main body 1, and a plurality of the first chambers 2 are arranged in sequence around the outer peripheral wall of the pump body 3, the pump body 3 is communicated with the first chamber 2, and an exhaust pipe 7 and an intake pipe 8 are disposed on the pump body 3, the exhaust pipe 7 is used to discharge the gas in the first chamber 2 out of the main body 1, and the intake pipe 8 is used to guide the gas outside the main body 1 into the pump body 3. In this technical solution, the first chamber 2 is inflated or exhausted through the pump body 3, the exhaust pipe 7 and the intake pipe 8, so as to achieve air pressure regulation. Preferably, there are three first chambers 2, and the pump body 3 can also support the compressor. Furthermore, multiple first chambers 2 can use the same pump body 3, that is, multiple first chambers 2 are pressure-regulated through the exhaust pipe 7 and the intake pipe 8 of the same pump body. Of course, multiple pump bodies can also be used. Correspondingly, each first chamber 2 is provided with a pump body 3, an exhaust pipe 7 and an intake pipe 8, and the multiple pump bodies 3 are arranged in a ring shape. The multiple pump bodies 3 and the first chamber 2 correspond one by one. Along the radial direction of the main body 1, the pump body 3 is located on the radial inner side of the first chamber 2, and the first chamber 2 is arranged in a ring shape, so as to adjust the force in various directions of the main body 1.

[0041] In some embodiments, the foot pad structure includes a first partition 4, and two adjacent first chambers 2 are separated by the first partition 4. In this technical solution, the main body 1 has an annular air pressure chamber, and the pump body 3 is located in the ring of the annular air pressure chamber, that is, the air pressure chamber is arranged around the pump body 3, and the first partition 4 is arranged along the radial direction of the main body 1, thereby dividing the air pressure chamber into a plurality of first chambers 4, so as to adjust the force of each direction of the main body 1.

[0042] In some embodiments, the balancing assembly 5 includes a balancing chamber, the balancing chamber is located in the main body 1, a sphere 9 is arranged at the center of the balancing chamber, and a plurality of the first chambers 2 are arranged in sequence along the circumference of the balancing chamber. In this technical solution, a plurality of sensors are arranged in the balancing chamber through the balancing chamber and the sphere 9, and the plurality of sensors are arranged at intervals along the circumference of the main body 1. When the compressor is in a balanced state, that is, when the main body 1 is subjected to balanced force, the sphere 9 is located at the center of the balancing chamber. When the compressor is in an unbalanced state, that is, when the main body 1 is subjected to unbalanced force, that is, at this time, the compression amount of part of the main body 1 is large and the compression amount of part is small, the sphere 9 will roll to the direction with greater force. After the sensor in this direction detects the sphere 9, the pump body 3 adjusts the air pressure of the first chamber 2 in this direction, so that the compressor reaches a balanced state again. Here, the balanced force of the main body 1 means that the center of gravity of the compressor coincides with the center line of the main body 1.

[0043] In some embodiments, a plurality of second partitions 11 are provided in the balance chamber, and the second partitions 11 are arranged at intervals along the circumference of the balance chamber, and the second partitions 11 divide the balance chamber into a plurality of second chambers 10, and the ball 9 can move into any of the second chambers 10 according to the force condition of the main body 1. In this technical solution, a plurality of second partitions 11 are provided in the balance chamber, and the second partitions 11 are arranged at intervals along the circumference of the balance chamber, and the second partitions 11 divide the balance chamber into a plurality of second chambers 10. To ensure that the ball 9 can roll into the second chambers 10 in all directions, the second chamber 10 is an open chamber, that is, the second chamber 10 has an opening, and the ball 9 can roll into the second chamber 10 through the opening. Sensors are provided in each second chamber 10 and at the center of the balance chamber, so as to detect the state of the ball 9 in real time and judge the force condition of the main body 1.

[0044] In some embodiments, an opening is formed between two adjacent ends of the second partitions 11 facing away from the inner wall of the balancing chamber, the second partitions 11 are arranged at intervals along the circumference of the sphere 9, and the opening faces the sphere 9. In this technical solution, an opening is formed between two adjacent ends of the second partitions 11 facing away from the inner wall of the balancing chamber, the second partitions 11 are arranged at intervals along the circumference of the sphere 9, and the opening faces the sphere 9, that is, along the circumference of the sphere 9, the second chambers 10 are arranged in sequence, the second chambers 10 are arranged around the sphere 9, an opening is formed between two adjacent ends of the second partitions 11 facing away from the inner wall of the balancing chamber, and there is a gap between the ends of the two adjacent second partitions 11 facing away from the inner wall of the balancing chamber and the sphere 9, thereby ensuring that the second partitions 11 will not affect the rolling of the sphere 9, and the sphere 9 can smoothly roll into the second chamber.

[0045] In some embodiments, the first chamber 2 and the second chamber 10 are arranged in a one-to-one correspondence. In this technical solution, the first chamber 2 and the second chamber 10 are arranged in a one-to-one correspondence, so that the air pressure of the first chamber 2 in each direction of the main body 1 can be accurately adjusted. Preferably, in the foot pad structure of the present invention, the first chamber 2 and the second chamber 10 are three.

[0046] The related art discloses a double-layer structure foot pad, in which the upper end surface of the inner layer structure is higher than the upper end surface of the outer layer structure. When the force applied by the compressor support foot on the upper end surface of the inner layer structure changes, the height of the inner layer structure also changes. When the inner and outer layer upper end surfaces are parallel, the entire foot pad is stressed, thereby achieving changes in the stiffness and structural damping of the foot pad. Although this solution can adjust the stiffness of the foot pad, it does not solve the problem of unbalanced force on the three foot pads caused by the structure of the compressor;

[0047] The related technology also discloses a compressor vibration isolation structure, including: an elastic foot pad, a piezoelectric gasket, a fixing bolt and a fixing nut, the piezoelectric gasket is arranged on the upper part of the elastic foot pad, and the piezoelectric gasket can be deformed in the axial direction when powered on; the fixing bolt is passed through the elastic foot pad and the piezoelectric gasket; the fixing nut is sleeved on the upper part of the fixing bolt, and the gap between the upper surface of the piezoelectric gasket and the lower surface of the fixing nut in the power-off state is smaller than the gap between the upper surface of the piezoelectric gasket and the lower surface of the fixing nut in the power-on state. The compressor vibration isolation structure provided by the present invention adopts the combination of elastic foot pads and piezoelectric gaskets, which can better meet the requirements of falling transportation and stress, and at the same time has better vibration reduction and noise reduction performance. Although this scheme can adjust the stiffness of the foot pad, it does not solve the problem of unbalanced force on the three foot pads caused by the structure of the compressor;

[0048] The patent disclosed in the related technology mainly protects a testing technology. The air spring is designed on a test bench. When the structure and stiffness of the foot pad need to be designed, the compressor can be installed on the bench. By adjusting the internal air pressure of the air spring vibration isolation foot pad and testing the vibration of the upper and lower ends of the foot pad, the optimal state of vibration reduction is selected, and the optimal mechanical performance parameters and stiffness parameters of each vibration isolation foot pad are calculated through the inflation volume, providing ideas for the structural design of rubber vibration isolation foot pads.

[0049] The patent disclosed in the related technology mainly judges the size of the vibration deformation by the current generated by the coil inside the vibration-damping pad cutting the magnetic lines of force of the magnetic core during the vibration process. When the deformation changes greatly, it can be adjusted by adjusting the inflation volume to ensure that the current size of each pad is consistent, thereby ensuring the consistency of deformation and reducing vibration.

[0050] The foot pad structure of the present invention is an integrated design, and a higher inflation volume is preset at the factory to ensure that the hardness of the entire foot pad is above 70 and has greater rigidity, so that the compressor will not shake greatly during transportation, causing large deformation and damage to the pipeline; further, when the user uses it for the first time at home, after the user turns on the power, the pump body 3 in the foot pad discharges part of the gas, so that the hardness range of the entire foot pad is within the range of 30-40, which can have higher flexibility when the compressor is running, and realize the transmission of attenuated vibration; and in the actual operation process, when the compressor has a more obvious amplitude, the balancing ball 9 in the balancing chamber rolls, and the balancing chamber is composed of a central area and a pressure sensing area. When the balancing chamber rolls, it will leave the central area and enter the pressure sensing area. At this time, an instruction is sent to the system to increase the inflation volume of the second chamber 10 in this area or reduce the inflation volume of other second chambers 10, so that the balancing ball 9 is in the central area of ​​the balancing chamber to reduce the vibration of the compressor.

[0051] In some embodiments, a groove 6 is provided on the main body 1, and the groove 6 is used to install the compressor 12, and the center of the groove 6, the center of the balance chamber, and the center of the sphere 9 are all located on the same center line of the main body 1. In this technical solution, the center of the groove 6, the center of the balance chamber, and the center of the sphere 9 are all located on the same center line of the main body 1, so that the center of gravity of the compressor 12 is located on the center line of the main body 1, thereby accurately judging the balance state of the compressor 12. The groove 6 does not penetrate the main body 1.

[0052] The foot pad structure of the present invention uses the ball 9 to monitor the vibration of the compressor, monitors and adjusts to ensure that the compressor is in a balanced position, and reduces the vibration of the compressor; the first cavity 2 is used to adjust the gas filling amount to achieve a good vibration reduction effect under different working conditions. The foot pad structure of the present invention solves the problem that the compressor center of gravity is not centered, resulting in uneven force on the compressor foot pad and large compressor shaking; it also solves the problem that the vibration reduction effect of the compressor foot pad is limited by the material and structural form of the foot pad, and cannot meet the vibration reduction requirements under various working conditions.

[0053] The foot pad structure of the present invention achieves a stable center of gravity of the compressor through gas regulation, and can meet the vibration reduction requirements under various working conditions. The sphere 9 is used to confirm whether the compressor is in a balanced state to avoid pipeline deformation caused by the unbalanced center of gravity of the compressor. The sphere 9 is used to monitor the vibration of the compressor, monitor and adjust to ensure that the compressor is in a balanced position, and reduce the vibration of the compressor; the first cavity 2 is used to adjust the gas filling amount to achieve better vibration reduction effects under different working conditions.

[0054] In some embodiments, the balance chamber is located between the groove 6 and the pump body 3, and the pump body 3 is embedded in the main body 1. In this technical solution, the balance chamber is located between the groove 6 and the pump body 3, and the pump body 3 is embedded in the main body 1. The pump body 3 can support the balance chamber to ensure the accuracy of the balance chamber in detecting the balance state of the compressor 12. The foot pad structure of the present invention sets the pump body 3 below the balance chamber as a support for the balance chamber. Of course, the pump body 3 can also be set outside the foot pad structure, as long as the pipeline of the pump body 3 is connected to the first chamber 2 to realize suction and exhaust.

[0055] The foot pad structure of the present invention has a main body 1 made of foot pad rubber. The pump body 3 is integrated with the balance component, and the pump body 3 is embedded inside the main body 1, which can avoid direct contact between the pump body and the chassis, and avoid the vibration of the pump body during operation being directly transmitted to the chassis 13. There are three second partitions 11 inside the balance chamber of the main body 1, and a sphere 9 is arranged at the center. There are also three first partitions 4 in the air pressure chamber to divide the air pressure chamber into three first chambers 2, and each of the three first chambers 2 has an exhaust pipe 7 and an intake pipe 8 connected to the pump body 3. The foot pad structure of the present invention is filled with air of a relatively high density during production, so that the rigidity of the entire compressor foot pad is relatively large and no obvious deformation will occur, thereby ensuring that the foot pad will not be significantly deformed during transportation, causing damage to the compressor pipeline or structural parts due to the impact during transportation. When the prototype arrives at the user's home and is powered on, the foot pad pump body 3 will extract part of the gas in the foot pad to increase the flexibility of the foot pad, keep the overall hardness of the three first chambers 2 of the foot pad between 30-40, and at the same time, through the different inflation amounts in the three first chambers 2, ensure that the balancing ball 9 in the balancing chamber is located in the center of the balancing chamber. When the air conditioner is running, the compressor 2 vibrates, and the compressor shakes at this time. The balancing ball 9 in the foot pad 1 rolls toward the second chamber 10 divided by the second partition 11 with the vibration. When the system detects which second chamber 10 the balancing ball 9 moves to, the pump body 3 will inflate the corresponding first chamber 2 through the inflation tube 7 to ensure that the balancing ball 9 is in the center of the balancing chamber, thereby ensuring that the compressor 2 is in a balanced state, avoiding the transmission of vibration, and making the foot pad have a better vibration isolation and vibration reduction effect. When the gas filling amount in a first chamber 2 makes the overall hardness of the chamber exceed the maximum value, the pump body 3 will extract the gas of the corresponding chamber through the corresponding exhaust pipe 8 of other chambers, so that the balancing ball 9 is located in the center of the balancing chamber, ensuring that the foot pad has a better vibration isolation and vibration reduction effect. The foot pad in this solution can effectively adjust the hardness of the foot pad under different operating conditions of the air conditioner, and can have better versatility and vibration reduction effect.

[0056] See also Fig.16As shown, the foot pad structure of the present invention is filled with air of relatively high density during production. At this time, the initial air volume in the first chamber is P0, which makes the rigidity of the entire compressor foot pad relatively large, that is, the hardness of the main body 1 is greater than 70, and no obvious deformation will occur, thereby ensuring that the foot pad will not be significantly deformed during transportation, causing damage to the compressor pipeline or structural parts due to impact during transportation. When the prototype arrives at the user's home and is powered on, the foot pad pump body 3 will extract part of the gas in the foot pad to increase the flexibility of the foot pad, until the air volume in the first forced is P1, maintaining the overall hardness of the three first chambers 2 of the foot pad between 30-40, and at the same time, through the different air volumes in the three first chambers 2, ensuring that the balancing ball 9 in the balancing chamber is located at the center of the balancing chamber. When the air conditioner is running, the compressor 2 vibrates, and the compressor shakes at this time. The balancing ball 9 in the foot pad 1 rolls toward the second chamber 10 divided by the second partition 11 with the vibration. When the system detects which second chamber 10 the balancing ball 9 moves to, the pressure value in the first chamber 2 corresponding to the ball 9 is judged at this time. When the hardness of the first chamber 2 is less than 33, the pump body 3 inflates the first chamber 2 corresponding to the ball 9 until the compressor reaches balance, that is, the ball 9 is located in the center of the balance chamber. When the hardness of the first chamber 2 corresponding to the ball 9 is greater than 37, the pump body 3 exhausts the first chamber 2 corresponding to the ball 9 until the compressor reaches balance, that is, the ball 9 is located in the center of the balance chamber. When the hardness of the first chamber 2 corresponding to the ball 9 is not less than 33 and not greater than 37, the pump body 3 exhausts the first chamber 2 not corresponding to the ball 9 until the compressor reaches balance, that is, the ball 9 is located in the center of the balance chamber, thereby ensuring that the compressor 2 is in a balanced state, avoiding the transmission of vibration, and making the foot pad have a better vibration isolation and vibration reduction effect. When the gas filling amount in a first chamber 2 makes the overall hardness of the chamber exceed the maximum value, the pump body 3 will extract the gas of the corresponding chamber through the corresponding exhaust pipe 8 of other chambers, so that the balancing ball 9 is located in the center of the balancing chamber, ensuring that the foot pad has a better vibration isolation and vibration reduction effect. The foot pad in this solution can effectively adjust the hardness of the foot pad under different operating conditions of the air conditioner, and can have better versatility and vibration reduction effect.

[0057] The present invention also provides a compressor, comprising the above-mentioned foot pad structure.

[0058] The bottom of the compressor 12 is installed in the groove 6, and the main body 1 is installed on the chassis 13, wherein the lower end surface of the main body 1 is directly in contact with the chassis 13. To ensure that they do not slide relative to each other, they can be glued together, or fixed by snaps or other methods. The chassis 13 and the compressor 2 are assembled with the main body 1 and the groove 6 and the bottom of the compressor. Of course, the main body 1 and the compressor 2 can also be assembled in other ways, and the chassis 13, the compressor 2, and the main body 1 can also be assembled in other ways.
