Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of compressors, and particularly relates to a foot pad structure and a compressor. BACKGROUND

[0002] The rotor type compressor is widely applied in the field of air conditioners due to its simple structure and low cost. The rotor type compressor is generally composed of a main cylinder body, a liquid storage barrel, a base foot and a rubber foot pad. Due to the existence of the liquid storage barrel, the gravity center of the compressor is not at the geometric center of the main cylinder body. The existing compressor base foot is too simple to install, is evenly distributed around the main cylinder body in the horizontal plane, and has the same height in the vertical direction, without fully considering the different forces on the damping rubber foot pad under the actual compressor base foot. In this way, the compressor is always in an inclined state, and the vibration energy is not uniformly attenuated through the rubber foot pad, which easily leads to abnormal vibration and noise. Moreover, the damping effect of the compressor foot pad is limited by the material and structure form of the foot pad, and cannot meet the damping requirements in various working conditions.

[0003] Since the compressor foot pad in the prior art cannot meet the damping requirements in various working conditions, the compressor has the technical problems of loud noise and poor user experience, and therefore the application researches and designs a foot pad structure and a compressor. SUMMARY

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

In this technical solution, when the compressor is installed on the main body 1, the balance assembly 5 is used to determine whether the force on the main body 1 is balanced, so as to determine whether the compressor is in a balanced state. Since the plurality of 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 in the corresponding direction is adjusted by adjusting the air pressure in each direction of the first chamber 2 in the main body 1, so that the compressor remains balanced. The main body 1 is made of a damping material, thereby effectively damping the compressor and reducing the noise of the compressor. The first chamber 2 is a closed chamber.

[0040] In some embodiments, a pump body 3 is arranged in the main body 1, the plurality of first chambers 2 are arranged in sequence around the outer peripheral wall of the pump body 3, the pump body 3 is in communication with the first chambers 2, and an exhaust pipe 7 and an air suction pipe 8 are arranged on the pump body 3. The exhaust pipe 7 is used to exhaust the gas in the first chamber 2 out of the main body 1, and the air suction pipe 8 is used to guide the gas outside the main body 1 into the pump body 3. In this technical solution, the pump body 3, the exhaust pipe 7 and the air suction pipe 8 are used to inflate or deflate the first chamber 2, thereby achieving air pressure adjustment. Preferably, the first chamber 2 is three, the pump body 3 can also support the compressor, and further, the plurality of first chambers 2 can use the same pump body 3, that is, the plurality of first chambers 2 are adjusted in air pressure by the exhaust pipe 7 and the air suction pipe 8 of the same pump body.

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, thereby adjusting the force on each direction of the main body 1.

[0041] In some embodiments, the foot pad structure comprises a first partition plate 4, and adjacent two first chambers 2 are spaced apart by the first partition plate 4. In this technical solution, the main body 1 has a ring-shaped air pressure chamber, the pump body 3 is located in the ring-shaped inner side of the ring-shaped air pressure chamber, that is, the air pressure chamber is arranged around the pump body 3, and the first partition plate 4 is arranged along the radial direction of the main body 1, thereby separating the air pressure chamber into a plurality of first chambers 4, thereby adjusting the force on each direction of the main body 1.

[0042] In some embodiments, the balancing assembly 5 comprises a balancing chamber located in the main body 1, a ball 9 is arranged at the center of the balancing chamber, and a plurality of the first chambers 2 are sequentially arranged along the circumference of the balancing chamber. In this technical solution, the balancing chamber and the ball 9 are provided with a plurality of sensors arranged at intervals along the circumference of the main body 1. When the compressor is in a balanced state, that is, the main body 1 is balanced, the ball 9 is located at the center of the balancing chamber. When the compressor is in an unbalanced state, that is, the main body 1 is unbalanced, that is, at this time, the compression amount of part of the main body 1 is large, and the compression amount of part of the main body 1 is small. The ball 9 will roll to the direction with larger force. When the ball 9 is detected by the sensor in this direction, the pump body 3 adjusts the air pressure of the first chamber 2 in this direction, so that the compressor re-achieves a balanced state. Here, the balanced state 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 arranged in the balancing chamber at intervals along the circumference of the balancing chamber, the second partitions 11 divide the balancing 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 arranged in the balancing chamber at intervals along the circumference of the balancing chamber, and the second partitions 11 divide the balancing chamber into a plurality of second chambers 10. In order to ensure that the ball 9 can roll into the second chamber 10 in each direction, 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. Each second chamber 10 and the center of the balancing chamber are provided with sensors to detect the state of the ball 9 in real time and determine the force condition of the main body 1.

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

[0045] In some embodiments, the first chamber 2 is arranged one-to-one with the second chamber 10. In this technical solution, the first chamber 2 is arranged one-to-one with the second chamber 10, 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 application, three first chambers 2 are arranged one-to-one with the second chamber 10.

[0046] The related technology discloses a double-layer structure foot pad, wherein the upper end face of the inner layer structure is higher than the upper end face of the outer layer structure, the force applied by the compressor foot on the upper end face of the inner layer structure changes, the height of the inner layer structure also changes, and when the upper end faces of the inner layer structure and the outer layer structure are parallel, the entire foot pad is stressed, so that the stiffness and structural damping of the foot pad are changed. Although this scheme can adjust the stiffness of the foot pad, it does not solve the problem of unbalanced stress of the three foot pads caused by the structure of the compressor;

[0047] The related technology also discloses a compressor vibration isolation structure, which comprises an elastic foot pad, a piezoelectric pad, a fixing bolt and a fixing nut, the piezoelectric pad is arranged on the upper portion of the elastic foot pad, the piezoelectric pad can be deformed in the axial direction when powered on, the fixing bolt is arranged through the elastic foot pad and the piezoelectric pad, the fixing nut is sleeved on the upper portion of the fixing bolt, and the gap between the upper surface of the piezoelectric pad in the power-off state and the lower surface of the fixing nut is smaller than the gap between the upper surface of the piezoelectric pad in the power-on state and the lower surface of the fixing nut. The compressor vibration isolation structure provided by the application adopts the cooperation of the elastic foot pad and the piezoelectric pad, can better meet the requirements of drop transportation and stress, and has good 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 stress of the three foot pads caused by the structure of the compressor;

[0048] The related technology also discloses a patent mainly protecting a test technology, and 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 test bench, the internal air pressure of the air spring vibration isolation foot pad is adjusted, the vibration amounts of the upper end and the lower end of the foot pad are tested, the state with the optimal vibration amount reduction is selected, the optimal mechanical performance parameters stiffness parameters of each vibration isolation foot pad are calculated through the air charge amount, and a design idea is provided for the structural design of the rubber vibration isolation foot pad.

[0049] The related technology also discloses a patent mainly through the fact that the magnetic force lines of the magnetic core are cut by the coil in the vibration process to generate an electric current, so that the vibration deformation is judged. When the deformation amount changes greatly, the air charge amount can be adjusted to ensure that the current of each foot pad is consistent, so that the deformation amount is consistent and the vibration is reduced.

[0050] The foot pad structure of the present application is an integrated design, and a higher inflation amount is preset when leaving the factory, so as to ensure that the hardness of the whole foot pad is above 70, and the rigidity is larger, so that the compressor does not appear large shaking during the transportation process, and the pipeline does not appear large deformation and damage; further, when the user uses it for the first time at home, the user powers on, the pump body 3 in the foot pad discharges part of the gas, so that the hardness of the whole foot pad is in the range of 30-40, and the flexibility is higher when the compressor is running, so as to realize the transmission of vibration attenuation; and in the actual running process, when the compressor appears a relatively obvious amplitude, the balance ball 9 in the balance chamber appears rolling, the balance chamber is composed of a central area and a pressure sensing area, when the balance chamber appears rolling, it will leave the central area and enter the pressure sensing area, at this time, an instruction is sent to the system, the inflation amount of the second chamber 10 in the area needs to be increased or the inflation amount of other second chambers 10 needs to be reduced, so as to make the balance ball 9 in the central area of the balance chamber, and reduce the vibration of the compressor.

[0051] In some embodiments, a groove 6 is arranged on the main body 1, the groove 6 is used for installing the compressor 12, the center of the groove 6, the center of the balance chamber, and the center of the ball 9 are 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 ball 9 are located on the same center line of the main body 1, so that the gravity center of the compressor 12 is located on the center line of the main body 1, so as to accurately judge 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 application uses the ball 9 to monitor the vibration condition 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 for adjusting the gas filling amount, so as to have a good vibration reduction effect under different working conditions. The foot pad structure of the present application solves the problems that the gravity center of the compressor is not centered, the compressor foot pad is not stressed uniformly, and the compressor shakes greatly; and solves the problem that the vibration reduction effect of the compressor foot pad is limited by the material and structure form of the foot pad, and cannot be used for vibration reduction under various working conditions.

[0053] The foot pad structure of the present application realizes stable gravity center of the compressor through gas adjustment, and can be used for vibration reduction under various working conditions, uses the ball 9 to confirm whether the compressor is in a balanced state, avoids the deformation of the pipeline caused by the unbalanced gravity center of the compressor, uses the ball 9 to monitor the vibration condition 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 for adjusting the gas filling amount, so as to have a good vibration reduction effect under different working conditions.

[0054] In some embodiments, the balance chamber is located between the groove 6 and the pump body 3 embedded in the main body 1. In this technical solution, the balance chamber is located between the groove 6 and the pump body 3 embedded in the main body 1, and 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 application 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 arranged outside the foot pad structure, as long as the pipeline of the pump body 3 is connected with the first chamber 2 to realize air suction and exhaust.

[0055] The foot pad structure of the present application adopts foot pad rubber for the main body 1. The pump body 3 is integrated with the balance assembly, and the pump body 3 is embedded in the main body 1, which can avoid direct contact between the pump body and the chassis and avoid direct transmission of vibration of the pump body to the chassis 13 during operation. The balance chamber of the main body 1 has three second partitions 11 in the center, and a ball 9 is arranged in the center. The air pressure chamber also has three first partitions 4 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 air suction pipe 8 connected with the pump body 3. The foot pad structure of the present application is filled with air of relatively large density during production, so that the entire compressor foot pad has relatively large rigidity and will not be deformed obviously, thereby ensuring that the foot pad will not be deformed obviously during transportation to cause damage to the compressor pipeline or structural parts due to impact during transportation. When the sample machine 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, so that the overall hardness of the three first chambers 2 of the foot pad is maintained between 30-40, and at the same time, through different gas filling amounts in the three first chambers 2, the balance ball 9 in the balance chamber is located at the center position of the balance chamber. When the compressor 2 vibrates during air conditioner operation, the balance ball 9 in the foot pad 1 rolls to the second chamber 10 divided by the second partition 11 due to vibration, and when the system detects the movement of the balance ball 9 to which second chamber 10, the pump body 3 will charge the corresponding first chamber 2 through the charging pipe 7 to ensure that the balance ball 9 is located at the center position of the balance chamber, thereby ensuring that the compressor 2 is in a balanced state and avoiding vibration transmission, so that the foot pad has better vibration isolation and reduction effect. When the gas filling amount in a certain first chamber 2 makes the overall hardness of the chamber exceed the maximum value, the pump body 3 will extract the gas in the corresponding chamber through the corresponding exhaust pipe 8 of the other chamber, so that the balance ball 9 is located at the center position of the balance chamber, thereby ensuring that the foot pad has better vibration isolation and reduction effect. The foot pad in this scheme can effectively adjust the hardness of the foot pad under different operating conditions of the air conditioner, and has better universality and vibration reduction effect.

[0056] For reference Figure 16As shown, the foot pad structure of the present application is filled with air of a larger density during production, at this time the initial air filling amount in the first chamber is P0, so that the stiffness of the entire compressor foot pad is larger, that is, the hardness of the main body 1 is greater than 70, and no obvious deformation occurs, so as to ensure that the foot pad does not have obvious deformation during transportation, so that the compressor pipeline or structural member does not be damaged by the impact during transportation. When the prototype reaches 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 amount in the first forced is P1, the overall hardness of the three first chambers 2 of the foot pad is maintained between 30-40, and at the same time, through the different air filling amounts in the three first chambers 2, it is ensured that the balance ball 9 in the balance chamber is located at the center position of the balance chamber. When the air conditioner is running, the compressor 2 generates vibration, at this time the compressor appears to shake, the balance ball 9 in the foot pad 1 rolls to the second chamber 10 divided by the second partition plate 11 with vibration, when the system detects the movement of the balance ball 9 to which second chamber 10, at this time, the pressure value in the first chamber 2 corresponding to the ball 9 is judged, when the hardness of the first chamber 2 is less than 33, the pump body 3 fills air into the first chamber 2 corresponding to the ball 9, until the compressor reaches balance, that is, the ball 9 is located at the center of the balance chamber, when 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 at 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 at the center of the balance chamber, thereby ensuring that the compressor 2 is in a balanced state, avoiding the transmission of vibration, so that the foot pad has better vibration isolation and reduction effect. When the gas filling amount in a certain first chamber 2 makes the overall hardness of the chamber exceed the maximum value, the pump body 3 will extract the gas in the corresponding chamber through the other chamber corresponding exhaust pipe 8, so that the balance ball 9 is located at the center position of the balance chamber, so as to ensure that the foot pad has better vibration isolation and reduction effect. The foot pad in the present scheme can effectively adjust the hardness of the foot pad under different operating conditions of the air conditioner, and has better universality and vibration reduction effect.

The bottom plate 13 and the compressor 2 are assembled through the main body 1 and the groove 6 cooperating with the bottom of the compressor, of course, the main body 1 and the compressor 2 can also adopt other assembly methods, and the bottom plate 13, the compressor 2 and the main body 1 can also adopt other assembly methods.
