[0063] The main source of the vibration noise of the refrigerator is caused by the operation of the compressor. When the compressor runs at high speed, there will be a buzzing noise in the compressor compartment. Sometimes, the vibration displacement of the compressor pipeline can even be visually observed. The reason is that the existence of rotational inertia torque and reciprocating inertia torque will cause crosstalk in the horizontal and vertical directions, resulting in varying degrees of vibration of the compressor, connecting pipeline, and foot pads. The occurrence of refrigerator vibration noise can be divided into three aspects: "excitation - transmission - response". Currently, for the refrigerator vibration phenomenon, most research is carried out on the excitation link (the pipeline of the compressor itself), and relatively mature theories have been summarized. The purpose of reducing the refrigerator vibration noise is achieved by reducing the vibration of the compressor pipeline itself. However, no analysis has been done on the transmission path. Therefore, it is necessary to optimize the refrigerator vibration noise from the perspective of vibration transmission.

[0064] Based on this, the inventor uses a rubber foot pad to connect between the compressor of the refrigerator and the bottom plate of the refrigerator, and absorbs the vibration of the compressor through the internal friction of the rubber.

[0065] However, on the one hand, the long - term use of rubber products will cause rubber aging and failure. On the other hand, when the compressor operates at high speed, the vibration load changes suddenly. Although the rubber foot pad can provide a certain amount of damping, there is a lag and it cannot respond to the vibration displacement of the compressor in a timely manner. In addition, when the refrigerator is turned on and the compressor starts, the impact on the rubber soft pad is the greatest, and unreasonable rubber selection will cause the rubber soft pad to fail.

[0066] To solve the above - mentioned technical problems, in the refrigerator provided by this application, a magnetorheological vibration damping device is arranged at the bottom of the compressor. The magnetorheological vibration damping device is connected to the compressor and to the box body. The controller is electrically connected to the magnetorheological vibration damping device and also electrically connected to the compressor. In this way, the controller can control the magnitude of the current of the magnetorheological vibration damping device according to the working state of the compressor. According to the current, the magnetic field strength of the magnetorheological vibration damping device changes, and then the damping magnitude changes to absorb the vibration load and energy impact brought by the rotation of the compressor.

[0075] Refer to Figure 1 and Figure 2 As shown, this embodiment provides a refrigerator. Among them, the refrigerator can be a direct-cooling refrigerator or an air-cooling refrigerator.

[0076] In some embodiments, the refrigerator includes a cabinet 100.

[0077] In some embodiments, the cabinet 100 includes an outer shell 110.

[0078] The outer shell 110 is configured with a first accommodation cavity having a first access opening and a second access opening. The first access opening and the second access opening are respectively disposed on opposite sides of the outer shell 110 in the depth direction of the cabinet 100. The first access opening may be disposed on the front side of the outer shell 110, and the second access opening may be disposed on the rear side of the outer shell 110. Among them, when the user uses the refrigerator, the side close to the user is the front side.

[0079] In some embodiments, the cabinet 100 includes an inner liner 120.

[0080] The inner liner 120 is located inside the outer shell 110. The inner liner 120 forms at least one refrigerating compartment. The inner liner 120 has a third access opening, which is opposite to the first access opening. Items can be placed into the refrigerating compartment through the third access opening and the first access opening.

[0081] Among them, the number of refrigerating compartments may be at least one. When the number of refrigerating compartments is one, the refrigerating compartment may be any one of a refrigerating chamber, a freezing chamber, or a variable temperature chamber. When the number of refrigerating compartments is two or more, the multiple refrigerating compartments may include at least one or more of a refrigerating chamber, a freezing chamber, or a variable temperature chamber.

[0082] In some embodiments, the cabinet 100 includes a compressor compartment 130.

[0083] The compressor compartment 130 is located inside the outer shell 110. The opening of the compressor compartment 130 is opposite to the second access opening. The compressor 200, the condenser, etc. can be placed into the compressor compartment 130 through the second access opening and the opening.

[0084] In some embodiments, a foaming layer is filled between the inner liner 120, the outer shell 110, and the compressor compartment 130. The foaming layer is used to insulate and keep warm the refrigerating compartment, so as to ensure the refrigeration effect in the refrigerating compartment.

[0085] In some embodiments, the refrigerator includes a door body (not shown in the figure).

[0086] Among them, the door body is pivotally provided on the front side of the cabinet 100 to close and open the refrigerating compartment for taking and placing items in the refrigerating compartment. It should be noted that the number of door bodies may be one, two, or more.

[0087] In some embodiments, the refrigerator includes a refrigeration system.

[0088] The refrigeration system may include a compressor 200, a condenser, a throttling device, and an evaporator.

[0089] Among them, the compressor 200, the condenser, the throttling device and the evaporator are connected in series through pipelines in sequence, and a refrigerant flows in the pipelines. The compressor 200 and the condenser can be arranged in the compressor compartment 130.

[0090] When the compressor 200 works, the refrigerant at low temperature and low pressure is sucked into the compressor 200, compressed into a superheated gas at high temperature and high pressure in the cylinder of the compressor 200, and then discharged into the condenser. The refrigerant gas at high temperature and high pressure dissipates heat through the condenser, and its temperature continuously drops, gradually being cooled into a saturated vapor at normal temperature and high pressure, and further cooled into a saturated liquid. The pressure of the refrigerant remains almost unchanged during the entire condensation process. The throttling device can include a decompression pipe or an electronic expansion valve. In this application, the case where the throttling device includes a decompression pipe is taken as an example for description. The decompression pipe has a low cost and is not prone to abnormal failures. The condensed refrigerant saturated liquid is throttled and depressurized through the decompression pipe, and the refrigerant becomes a wet vapor at normal temperature and low pressure. Then, the wet vapor at normal temperature and low pressure absorbs heat and vaporizes through the evaporator, not only reducing the temperature of the evaporator and its surroundings, but also turning the refrigerant into a gas at low temperature and low pressure. The evaporator cools the air in the refrigerating compartment to lower the temperature of the refrigerating compartment. The refrigerant coming out of the evaporator returns to the compressor 200 again, repeating the above process, so that the refrigerating compartment can be maintained at a set temperature.

Figure 4 is Figure 3 a partial enlarged view of part A in Figure 5 It is a schematic structural diagram of a compressor, a magnetorheological vibration damping device and a bottom plate in the refrigerator provided by the embodiment of the present application from another angle. Figure 6 is Figure 5 a schematic structural diagram of part B in

[0092] Refer to Figures 3 to 6 As shown, in some embodiments, the refrigerator includes: a magnetorheological vibration damping device 300.

[0093] Among them, the magnetorheological vibration damping device 300 is located between the compressor 200 and the bottom plate 131 of the compressor compartment 130. The magnetorheological vibration damping device 300 is connected to the compressor 200 and connected to the bottom plate 131 of the compressor compartment 130.

[0094] In this way, the vibration generated by the compressor 200 is transmitted to the bottom plate 131 through the magnetorheological vibration damping device 300. The magnetorheological vibration damping device 300 absorbs the vibration load and energy impact brought by the rotation of the compressor 200 by changing the magnetic field strength and thus changing the damping magnitude.

[0095] In some embodiments, the number of magnetorheological damping devices 300 can be one, two, or more.

[0096] Figure 7 This is the control schematic diagram of the refrigerator provided by the embodiments of the present application.

[0097] See Figure 7 As shown, in some embodiments, the refrigerator includes a controller 400.

[0098] In some embodiments, the controller 400 can be located inside the cabinet 100. For example, inside the compressor compartment 130. Or the controller 400 is provided on the rear panel of the cabinet 100.

[0099] Among them, the controller 400 is electrically connected to the magnetorheological damping device 300 and is also electrically connected to the compressor 200.

[0100] Among them, the controller 400 is configured to energize the magnetorheological damping device 300. The controller 400 is configured to change the magnitude of the current supplied to the magnetorheological damping device 300.

[0101] The magnetorheological damping device 300 is configured to change the damping according to the current.

[0102] Among them, the controller 400 is configured to change the current of the magnetorheological damping device 300 according to the working state of the compressor 200. The magnetorheological damping device 300 is configured to change the damping according to the current. In this way, the controller 400 can control the magnitude of the current of the magnetorheological damping device 300 according to the working state of the compressor 200, and change the magnetic field strength of the magnetorheological damping device 300 according to the current, thereby changing the magnitude of the damping, so as to absorb the vibration load and energy impact brought by the rotation of the compressor 200.

[0103] Specifically, when the compressor 200 is not running, the magnetorheological damping device 300 is in a power-off state.

[0104] When the refrigerator is working and the compressor 200 is running, the controller 400 energizes the magnetorheological damping device 300. After the magnetorheological damping device 300 is energized, a magnetic field will be formed, and the magnitude of the damping will change, responding in a timely manner to the vibration of the compressor 200.

[0105] When the compressor 200 is in the starting stage, by changing the magnitude of the current of the magnetorheological damping device 300, the magnetic field strength is changed, and then the magnitude of the damping is changed, so as to absorb the vibration load and energy impact brought by the rotation of the compressor 200.

[0106] It can be understood that in this embodiment, the magnetorheological damping device 300 is used to replace the rubber pad, effectively solving the problem of the rubber pad's lagging response and effectively solving the problem of the rubber pad aging and failing after long-term use.

[0107] Figure 8 Schematic diagram of the internal structure of the magnetorheological damping device in the refrigerator provided by the embodiment of the present application.

[0108] See Figure 8 As shown, in some embodiments of the present application, the magnetorheological damping device 300 includes an elastic outer shell 310. The elastic outer shell 310 can play a role in support and protection, and moreover, the elastic outer shell 310 can play a role in vibration damping.

[0109] Among them, the elastic outer shell 310 is configured with an inner cavity. The inner cavity is used to accommodate other components of the magnetorheological damping device 300.

[0110] In some embodiments, the material of the elastic outer shell 310 can be silica gel or rubber.

[0111] In some embodiments of the present application, the magnetorheological damping device 300 includes a first coil group 320. The first coil group 320 is used to generate a magnetic field.

[0112] Among them, the first coil group 320 is located in the inner cavity, and the first coil group 320 is electrically connected to the controller 400.

[0113] In some embodiments of the present application, the magnetorheological damping device 300 includes a second coil group 330. The second coil group 330 is used to generate a magnetic field.

[0114] Among them, the second coil group 330 is located in the inner cavity, and the second coil group 330 is electrically connected to the controller 400.

[0115] In some embodiments, the first coil group 320 and the second coil group are located on opposite sides of the inner cavity along the direction from the compressor 200 to the bottom plate. That is to say, the first coil group 320 and the second coil are located on the upper and lower sides in the vertical direction.

[0116] In some embodiments of the present application, the magnetorheological damping device 300 includes a magnetorheological fluid 340.

[0117] Among them, the magnetorheological fluid 340 is located in the inner cavity and is located between the first coil group 320 and the second coil group 330.

[0118] It should be noted that the magnetorheological fluid 340, also known as magnetic liquid, ferrofluid or magnetic fluid, is a new type of functional material. It has both the fluidity of a liquid and the magnetism of a solid magnetic material. The magnetorheological fluid 340 is a stable colloidal liquid formed by mixing magnetic solid particles with a diameter of nanometer order (less than 10 nanometers), a base carrier liquid (also called a medium), and a surfactant. This fluid has no magnetic attraction when static, and only shows magnetism when an external magnetic field is applied. Among them, the first coil group 320 and the second coil group 330 are used to apply a magnetic field to the magnetorheological fluid 340.

[0119] Specifically, when the compressor 200 is not operating, the first coil group 320 and the second coil group 330 are in a power-off state.

[0120] When the refrigerator is working and the compressor 200 is operating, the controller 400 energizes the first coil group 320 and the second coil group 330. The current directions of the first coil group 320 and the second coil group 330 are opposite. After the first coil group 320 and the second coil group 330 are energized, a vertical magnetic field will be formed. The magnetorheological fluid 340 will sense the change in magnetic field strength and accumulate along the direction of the magnetic induction line, changing the damping magnitude and responding in a timely manner to the vibration of the compressor 200.

[0121] When the compressor 200 is in the starting stage, by changing the current magnitudes of the first coil group 320 and the second coil group 330, the magnetic field strength is changed, and then the damping magnitude is changed to absorb the vibration load and energy impact brought by the rotation of the compressor 200.

[0122] In some embodiments of the present application, the elastic housing 310 includes: an elastic sleeve 311.

[0123] In some embodiments, the material of the elastic sleeve 311 can be silicone or rubber. The elastic sleeve 311 can play a role in elastic deformation.

[0124] Among them, the elastic sleeve 311 is configured with a first cavity 3111, and the magnetorheological fluid 340 is located in the first cavity 3111.

[0125] In some embodiments of the present application, the elastic housing 310 includes: a first end cap 312.

[0126] In some embodiments, a second cavity 313 is formed between the first end cap 312 and the elastic sleeve 311, and the first coil group 320 is located in the second cavity 313.

[0127] It should be noted that the second cavity 313 and the first cavity 3111 can communicate with each other, or the second cavity 313 and the first cavity 3111 can be separated from each other.

[0128] In some embodiments of the present application, the first end cap 312 is arranged on the top of the elastic sleeve 311 and is snap-connected to the elastic sleeve 311. In this way, the installation efficiency is relatively high, and it is convenient to repair the first coil group 320.

[0129] In some embodiments, the first end cap 312 can be a plastic part.

[0130] In some embodiments of the present application, the elastic housing 310 includes: a second end cap 314.

[0131] In some embodiments, a third cavity 315 is formed between the second end cap 314 and the elastic sleeve 311, and the second coil group 330 is located within the third cavity 315.

[0132] It should be noted that the third cavity 315 and the first cavity 3111 may communicate with each other, or the third cavity 315 and the first cavity 3111 may be separated from each other.

[0133] In some embodiments, the second end cap 314 is disposed at the bottom of the elastic sleeve 311 and is snap - connected to the elastic sleeve 311. In this way, the installation efficiency is relatively high, and it is convenient to repair the second coil group 330.

[0134] In some embodiments, the second end cap 314 may be a plastic part.

[0135] In some embodiments of the present application, in order to improve the vibration damping effect, the magnetorheological vibration damping device 300 further includes an elastic member 350.

[0136] The elastic sleeve 311 is configured with a fourth cavity 3112. The fourth cavity 3112 is separated from the first cavity 3111. The elastic member 350 is located within the fourth cavity 3112. One side of the elastic member 350 is connected to the inner top wall of the fourth cavity 3112, and the other side is connected to the inner bottom wall of the fourth cavity 3112.

[0137] Specifically, the elastic member 350 may be a spring.

[0138] When the refrigerator is not powered on, or when the compressor 200 is not operating, the first coil group 320 and the second coil group are in a power - off state. At this time, the elastic member 350 (in the initial state of energy storage) and the elastic sleeve 311 provide support.

[0139] In some embodiments of the present application, the first cavity 3111 is located within the region surrounded by the fourth cavity 3112.

[0140] In this way, the space of the fourth cavity 3112 is relatively large, which is beneficial to increasing the size of the elastic member 350, and thus beneficial to improving the vibration damping effect.

[0141] In some embodiments of the present application, the refrigerator further includes: a connecting member 500.
