[0001] This application belongs to the field of refrigerator technology, and particularly relates to a vibration damping component, a refrigeration system and a refrigerator. Background Technology
[0002] Refrigerator vibration and noise are important indicators of general concern to users. For refrigerators, pipe resonance in the compressor compartment is one of the main sources of noise and vibration in the compressor compartment. Therefore, reducing pipe vibration has become a research hotspot.
[0003] In particular, the intake connection pipe in the compressor compartment is relatively long. In related technologies, some methods are used to add something like vibration damping putty to the intake connection pipe to achieve a vibration reduction effect. However, the location where the vibration damping putty is added often does not correspond to the location where the pipe vibrates the most. Utility Model Content
[0004] This application provides a vibration damping component, a refrigeration system, and a refrigerator, which can reduce vibration noise at the location of the greatest pipeline vibration.
[0005] In a first aspect, embodiments of this application provide a vibration damping component applied to a refrigeration system, the refrigeration system including an intake connection pipe, the vibration damping component comprising:

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] Refrigerator vibration and noise are important indicators that users are generally concerned about. For refrigerators, pipe resonance in the compressor compartment is one of the main sources of noise and vibration in the compressor compartment. In recent years, reducing pipe resonance has become a research hotspot. Solutions to pipe vibration and noise include adding vibration damping blocks or vibration damping putty to the pipes.
[0030] Structurally, due to the length of the suction connection pipe, vibration damping putty needs to be added to the suction connection pipe to achieve a vibration reduction effect. However, one of the problems with using vibration damping putty is that, due to operator error, the vibration damping putty may not adhere tightly, causing it to fall off the pipe and affect the refrigerator noise. In addition, the location where the vibration damping putty is added may not be the location of the greatest pipe vibration, which means that the vibration reduction effect is not good.
[0031] In view of the above problems, this application provides a vibration damping component, a refrigeration system and a refrigerator, which will be described below with reference to the accompanying drawings.
[0032] Please see Figure 1 and Figure 2 As shown, Figure 1 This is a structural schematic diagram of the vibration damping component provided in an embodiment of this application. Figure 2 This is a structural block diagram of a vibration damping component provided in an embodiment of this application. For example, an embodiment of this application provides a vibration damping component 100 applied to a refrigeration system, which includes a suction connection pipe 200. The refrigeration system also includes components such as a compressor, compressor compartment, evaporator, and condenser, which are not limited herein.
[0033] The vibration damping component 100 is mainly used to dampen the suction connection pipe 200 to reduce the noise generated by the vibration of the suction connection pipe 200, thereby improving the user's experience of using the refrigerator.
[0034] The vibration damping assembly 100 includes a vibration sensor 110, a slider 120, and a controller 130.
[0035] Vibration sensor 110 is fixed to the intake connection pipe 200. Vibration sensor 110 is used to detect vibration data at its location. Vibration data includes vibration acceleration, vibration displacement or amplitude, and vibration frequency. In this embodiment, vibration acceleration is used as an example for illustration, and should not be construed as a limitation on vibration data.
[0036] The vibration sensors 110 can be multiple to detect vibration data at different locations on the intake connection pipe 200 and compare them to find the location of the maximum vibration and perform noise reduction processing.
[0037] The slider 120 is slidably connected to the suction connecting pipe 200, that is, the slider 120 can slide along the suction connecting pipe 200, thereby changing the relative position of the slider 120 and the suction connecting pipe 200. The slider 120 reduces vibration mainly by reducing the resonance of the suction connecting pipe 200 by its own weight, thereby reducing the vibration of the suction connecting pipe 200 at different positions.
[0038] The controller 130 is electrically connected to both the vibration sensor 110 and the slider 120. The controller 130 controls the slider 120 to slide to a preset position based on the vibration data from the vibration sensor 110. The controller 130 is the control center of the vibration damping assembly 100. It can process the vibration data from the vibration sensor 110, such as comparing the vibration data. The controller 130 also generates control signals based on the comparison of the vibration data, such as generating control signals to control the slider 120 to slide to a preset position for vibration acceleration at different locations. Alternatively, it can determine the control signal corresponding to the preset position of the slider 120 through a mapping relationship between vibration acceleration at different locations.
[0039] In the vibration damping component 100 provided in this application embodiment, the maximum vibration position of the intake connection pipe is detected by a vibration sensor, and the slider is controlled to slide to a preset position, which is also the maximum vibration position. This can reduce the vibration noise at the maximum vibration position of the intake connection pipe. Furthermore, the same slider can achieve noise reduction at different positions, saving components and thus improving the user's experience of using the refrigeration system and refrigerator.
[0040] Please see Figure 3 As shown, Figure 3This is another structural schematic diagram of the vibration damping component provided in the embodiments of this application. For example, the intake connection pipe 200 includes multiple straight segments 210 and multiple bent segments 220, each bent segment 220 being disposed between two adjacent straight segments 210. The number of straight segments 210 and bent segments 220 is not limited.
[0041] Because the intake connection pipe 200 is quite long, if only one vibration damper is installed, the position of the vibration damper may not match the position of the greatest vibration, or the position of the greatest vibration may be changing. Therefore, the vibration damping effect of a fixed vibration damper is not good. If multiple vibration dampers are installed, the number of devices needs to be increased, which takes up a lot of space and is not conducive to the miniaturization design of the refrigeration system.
[0042] Based on this, this embodiment of the application provides a sliding slider 120 to reduce vibration noise at different locations. To ensure that the slider 120 can dampen vibrations at the location with the greatest vibration, the number of vibration sensors 110 is not limited to one; for example, there may be at least two vibration sensors 110, each correspondingly disposed on one of the multiple straight segments 210 of the intake connecting pipe 200. For instance, the vibration damping component 100 may include three vibration sensors 110, each disposed on one of three of the multiple straight segments 210. This embodiment of the application uses three adjacent straight segments 210 as an example, and should not be construed as a limitation on the position of the straight segments 210.
[0043] When the three vibration sensors 110 detect the first acceleration, the second acceleration, and the third acceleration respectively, the controller 130 compares the first acceleration, the second acceleration, and the third acceleration. For example, when the second acceleration is the largest, that is, the second acceleration is greater than the first acceleration, and the first acceleration is greater than the third acceleration, the preset position is the position of the vibration sensor 110 that detected the second acceleration. Therefore, the controller 130 can control the slider 120 to slide to the preset position to reduce the vibration at the preset position.
[0044] If the slider 120 slides directly relative to the suction connecting pipe 200, it is easy to wear down the suction connecting pipe 200 and affect its function.
[0045] To reduce the impact on the intake connection pipe 200, the vibration damping component 100 of this embodiment further includes a guide rail 140, which is disposed along the intake connection pipe 200. The slider 120 has a groove 122, and the slider 120 cooperates with the guide rail 140 through the groove 122.
[0046] The movement of slider 120 also requires power from a driving component. Please refer to... Figures 1 to 3 And see Figure 4 As shown, Figure 4 This is another structural schematic diagram of the vibration damping component provided in the embodiments of this application. Exemplarily, the vibration damping component 100 further includes a driving member 150 and a traction member 160. The traction member 160 is fixedly connected to the slider 120, and the traction member 160 can be wound around the driving member 150. The driving member 150 is electrically connected to the controller 130, and the driving member 150 is used to drive the slider 120 through the traction member 160 according to the control signal from the controller 130. The driving member 150 may be a motor, and the traction member 160 may be a traction rope. For example, one end of the traction rope can be fixed to the slider 120, and the other end of the traction rope can be wound around the motor shaft, so that the rotation of the motor shaft can cause the traction rope wound around the motor shaft to achieve the purpose of pulling the slider 120.
[0047] To achieve the reciprocating motion of the slider 120, in one implementation, the vibration damping assembly 100 includes two driving members 150 and two traction members 160. The two driving members 150 drive the slider 120 from both ends of the slider 120, i.e., from both ends of the slider 120's direction of movement, through the two traction members 160, thereby achieving the reciprocating motion of the slider 120. The two driving members 150 can be electrically connected, or both driving members 150 can be electrically connected to the controller 130, thus allowing the two driving members 150 to move alternately. That is, when one driving member 150 is working, the other driving member 150 follows, unfolding the traction member 160 that cooperates with the other driving member 150, thereby improving the motion accuracy of the slider 120.
[0048] In another implementation, a driving element 150 and a traction element 160 can be provided at one end of the slider 120, and a reset element can be provided at the other end of the slider 120. The reset element can be an elastic element, which can reset the slider 120 to the initial position before each movement to the preset position, thus saving on the setting of components and reducing costs.
[0049] It should be noted that, in order to reduce the interference of the traction component 160 to other devices, the traction component 160 can be set to move in a predetermined track. For example, a guide groove can be set on the guide rail 140, and the traction component 160 can be set in the guide groove, so that the traction component 160 can move in the guide groove, which can reduce interference or movement disturbance to other devices.
[0050] In order to fix the slider 120 in the preset position, a telescopic component (not shown in the figure) can be provided for the slider 120, and a slot is provided at the preset position. That is, when the slider 120 moves to the preset position, the telescopic component extends and is locked in the slot, thereby temporarily fixing the slider 120 in the preset position.
