Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] A refrigerator is a common household appliance that can keep food or other items at a constant low temperature. The refrigerator includes a compressor, which can be used to suck in low-pressure refrigerant gas, compress it, and discharge high-pressure and high-temperature refrigerant gas. However, when the compressor is in operation, the compressor is prone to vibration, and the refrigerator produces a lot of noise. Utility Model Content

[0003] The embodiment of the present application provides a refrigerator, which can solve the technical problem that when the compressor is in a working state, the compressor is prone to vibrate, causing the refrigerator to generate loud noise.

[0004] In a first aspect, an embodiment of the present application provides a refrigerator, comprising a box, a compressor and a shock absorber, wherein the compressor is installed in the box through the shock absorber, and the shock absorber comprises:

[0005] A main body is fixedly connected to the box body, and a surface of the main body facing away from the box body is connected to the compressor; the main body is provided with a receiving cavity, and a plurality of movable vibration-damping particles are arranged in the receiving cavity;

[0006] A recessed portion is provided on a surface of the main body away from the box body, and the recessed portion accommodates at least a portion of the compressor; the recessed portion is provided with a vibration-damping connection layer, and a surface of the vibration-damping connection layer away from the recessed portion is connected to the compressor;

[0007] A support frame is arranged in the accommodating cavity, the support frame is fixed to the main body, and one end of the support frame facing away from the main body is connected to the surface of the recessed portion facing away from the vibration-damping connection layer.

[0008] The refrigerator of the embodiment of the present application is provided with a vibration damper, and the compressor can be installed in the box through the vibration damper. The vibration damper includes a main body and a recessed portion connected to each other, and the main body is provided with a receiving cavity, and the receiving cavity accommodates a plurality of movable vibration damping particles. The recessed portion is provided on the side of the main body away from the box, and at least part of the compressor can be provided in the recessed portion, and the recessed portion is provided with a vibration damping connection layer, and the surface of the vibration damping connection layer away from the recessed portion is connected to the compressor.

[0009] When the compressor is in operation, the compressor can generate vibrations and transmit vibration energy to the recessed portion through the vibration-damping connection layer, and the vibration-damping connection layer absorbs at least part of the vibration energy of the compressor. The compressor transmits vibration energy to the plurality of vibration-damping particles in the accommodating cavity through the recessed portion and the main body, and the plurality of vibration-damping particles move in the accommodating cavity, so that the plurality of vibration-damping particles in the accommodating cavity collide and rub against each other under the drive of the compressor, thereby reducing the vibration energy of the compressor, reducing the vibration energy transmitted by the compressor to the refrigerator body and other structures, and reducing the noise generated by the refrigerator.

[0010] In some embodiments of the present application, the compressor has a plurality of support legs, and the plurality of support legs are arranged around the outer side of the recessed portion, and the support legs face the surface of the main body away from the box body.

[0011] In this way, multiple support legs are arranged on the outside of the recessed portion, and the support legs are facing the surface of the main body away from the box body, so that the center of gravity of the compressor is closer to the recessed portion, making the connection between the compressor and the recessed portion more stable, reducing the possibility of the compressor shaking relative to the recessed portion.

[0012] In some embodiments of the present application, a surface of the main body facing away from the box is provided with a vibration-damping layer, and the bottom of the supporting foot is fixedly connected to the surface of the main body facing away from the box through the vibration-damping layer;

[0013] Alternatively, the bottom of the supporting foot is not in contact with the main body, and the surface of the vibration-damping connecting layer facing away from the recessed portion is in contact with the shell of the compressor.

[0014] In this arrangement, the bottom of the support foot is fixedly connected to the surface of the main body away from the box body through the vibration-damping layer, and the connection between the compressor and the vibration absorber is more stable. When the compressor is in a working state, part of the vibration energy of the compressor is transmitted to the main body through the support foot and the vibration-damping layer, so that part of the vibration energy can be absorbed by the vibration-damping layer.

[0015] The remaining vibration energy of the compressor can be transmitted to the recessed portion through the vibration-damping connecting layer, and the vibration-damping connecting layer absorbs at least part of the vibration energy of the compressor. Thus, the vibration-damping layer and the vibration-damping connecting layer cooperate to further improve the absorption effect of the compressor vibration energy and reduce the noise generated by the refrigerator.

[0016] Alternatively, the bottom of the support foot does not contact the main body, and the surface of the vibration-damping connecting layer facing away from the recessed portion is in contact with the compressor shell, so that the vibration energy of the compressor is transmitted to the recessed portion through the vibration-damping connecting layer, thereby reducing the possibility of collision and friction between the compressor support foot and the main body.

[0017] In some embodiments of the present application, the support frame includes a plurality of support portions, and at least some of the plurality of support portions are cross-arranged;

[0018] At least a portion of the support portion is provided with a through opening, and the through opening is at least used for the vibration-damping particles to pass through.

[0019] In this way, at least some of the multiple support parts are arranged crosswise, so that the support effect of the support frame on the recessed part can be improved, and the possibility of deformation of the recessed part can be reduced. At least some of the support parts are provided with openings for the vibration-damping particles to pass through, so that the vibration-damping particles can rub and collide with each other in the accommodating cavity, so that the vibration energy generated by the compressor can be absorbed by the multiple vibration-damping particles.

[0020] In some embodiments of the present application, the main body is provided with a filling port, the filling port is connected to the inner and outer sides of the accommodating cavity, and the filling port is at least used to put in or take out the vibration-damping particles.

[0021] With such arrangement, the filling port can communicate with the inner and outer sides of the accommodating cavity, so that a plurality of vibration-damping particles can be filled into the accommodating cavity of the main body through the filling port, thereby making the process of filling the accommodating cavity with vibration-damping particles more convenient.

[0022] In some embodiments of the present application, the filler port is configured as a filler threaded port, and the filler threaded port is configured on the side wall of the main body;

[0023] The vibration damper comprises a screw plug, which is threadedly connected to the filler threaded port, and the screw plug is at least used to close or open the filler threaded port.

[0024] With such arrangement, when it is necessary to put vibration-damping particles into the accommodating cavity, the vibration-damping particles can be put into the accommodating cavity from the outside of the accommodating cavity through the filler threaded opening. When the filling rate of the vibration-damping particles in the accommodating cavity reaches the required filling rate, the screw plug can be threadedly connected to the filler threaded opening, so that the filler threaded opening can be closed by the screw plug, making the accommodating cavity airtight.

[0025] In some embodiments of the present application, the shock absorber is provided with a fixing bolt, and the fixing bolt passes through the main body;

[0026] The bolt head of the fixing bolt abuts against the surface of the main body away from the box body, the threaded section of the fixing bolt penetrates the box body, and the threaded section of the fixing bolt is threadedly connected to the box body.

[0027] With such an arrangement, when the shock absorber is fixed relative to the box, the main body of the shock absorber can be placed in the box with the recessed portion of the shock absorber facing away from the box, and then the fixing bolt is passed through the main body so that the bolt head of the fixing bolt abuts against the surface of the main body facing away from the box, and the threaded section of the fixing bolt is passed through the box, and the threaded section of the fixing bolt is threadedly connected to the box, so that the shock absorber and the box can be fixed relatively to each other by the fixing bolt.

[0028] In some embodiments of the present application, a protection tube is provided in the accommodating cavity, and the protection tube is close to the inner wall of the main body;

[0029] The inner side of the protection tube is used to accommodate the fixing bolts, and the outer side of the protection tube is used to abut against the vibration-damping particles.

[0030] In this arrangement, the protective tube is close to the inner wall of the main body, the inner side of the protective tube is used to accommodate the fixing bolts, and the outer side of the protective tube is used to abut the vibration-damping particles. When the compressor is in working state, multiple vibration-damping particles move in the accommodating cavity, and the protective tube can play a certain isolation and blocking role for the vibration-damping particles and the fixing bolts, thereby reducing the possibility of the vibration-damping particles directly hitting the fixing bolts.

[0031] In some embodiments of the present application, the vibration-damping particles are configured as vibration-damping spherical particles; the particle size of the vibration-damping spherical particles is greater than or equal to 0.5 mm and less than or equal to 2 mm;

[0032] And / or, the filling rate of the vibration-damping particles is greater than or equal to 60% and less than or equal to 80%.

[0033] In this way, the vibration-damping particles are configured as vibration-damping spherical particles. By using spherical particles as vibration-damping particles, their surface area can be increased, and the efficiency of the vibration-damping particles in absorbing the vibration energy generated by the compressor can be improved, thereby reducing the vibration energy generated by the compressor from being transmitted to the refrigerator body.

[0034] The particle size of the vibration-damping spheres is greater than or equal to 0.5 mm and less than or equal to 2 mm, so that the multiple vibration-damping spheres located in the accommodating cavity can more easily collide and rub against each other, thereby improving the efficiency of the vibration-damping particles in absorbing the vibration energy generated by the compressor.

[0035] The filling rate of the vibration-damping particles is greater than or equal to 60% and less than or equal to 80%, thereby ensuring the vibration-damping effect and stability of the vibration absorber, while avoiding overfilling or underfilling, ensuring that the vibration absorber has sufficient elasticity and vibration-damping capacity during operation, and improving the overall vibration-damping effect.

[0036] In a second aspect, an embodiment of the present application provides a refrigerator, comprising a box, a compressor and a shock absorber, wherein the compressor is installed in the box through the shock absorber, and the shock absorber comprises a main body, a recessed portion and a support frame;

[0037] The main body is arranged in the box, and the main body is provided with a receiving cavity, and a plurality of movable vibration-damping particles are arranged in the receiving cavity; a vibration-damping connecting layer is arranged on the surface of the recessed portion away from the main body, and the supporting frame is arranged in the receiving cavity, and the supporting frame is at least used to support the recessed portion;

[0038] At least a portion of the compressor is disposed in the recessed portion, and the compressor is connected to the recessed portion through the vibration-damping connecting layer; when the compressor is in working state, the vibration-damping connecting layer absorbs at least a portion of the vibration energy of the compressor, and the multiple vibration-damping particles located in the accommodating cavity collide and rub against each other under the drive of the compressor to reduce the vibration energy of the compressor.

[0056] As described in the background art, in the related art, a refrigerator includes a compressor, which can be used to suck in a low-pressure refrigerant gas, compress and discharge a high-pressure and high-temperature refrigerant gas. The high-temperature and high-pressure refrigerant gas can dissipate heat through a condenser, so that it is cooled and becomes a high-pressure liquid. The high-pressure liquid refrigerant is decompressed through an expansion valve and becomes a low-pressure state, absorbing heat and achieving a refrigeration effect, thereby reducing the temperature of the refrigerator body. However, when the compressor is in a working state, the compressor is prone to vibration, and the refrigerator generates a lot of noise.

[0057] Although some existing vibration reduction devices have a certain buffering effect on the vibration of the compressor during operation, the vibration reduction effects of these vibration reduction devices are relatively not ideal. Figure 1 The vibration reduction of the compressor 100 can be achieved by relying on rubber vibration-damping pads 10. The rubber vibration-damping pads 10 can be used at the four feet of the compressor 100 for vibration reduction. The rubber vibration-damping pads 10 can be placed between the compressor 100 and the press support plate of the box body. Then, the compressor 100, the rubber vibration-damping pads 10 and the press support plate can be fastened together by bolts and other structures, thereby achieving vibration reduction of the compressor through the rubber vibration-damping pads.

[0058] However, rubber vibration damping pads are usually fully suspended vibration damping structures. Rubber vibration damping pads have obvious resonance points at low frequencies, and their vibration damping properties can be greatly reduced in low temperature environments. At the same time, the consistency and reliability of the structure are often not guaranteed, resulting in poor vibration damping effects of rubber vibration damping pads.

[0059] In view of this, the refrigerator of the embodiment of the present application is provided with a vibration damper, and the compressor can be installed in the box through the vibration damper. The vibration damper includes a main body and a recessed portion connected to each other, and the main body is provided with a receiving cavity, and the receiving cavity accommodates a plurality of movable vibration damping particles. The recessed portion is provided on the side of the main body away from the box, and at least part of the compressor can be provided in the recessed portion, and the recessed portion is provided with a vibration damping connection layer, and the surface of the vibration damping connection layer away from the recessed portion is connected to the compressor.

[0060] When the compressor is in operation, the compressor can generate vibrations and transmit vibration energy to the recessed portion through the vibration-damping connection layer, and the vibration-damping connection layer absorbs at least part of the vibration energy of the compressor. The compressor transmits vibration energy to the plurality of vibration-damping particles in the accommodating cavity through the recessed portion and the main body, and the plurality of vibration-damping particles move in the accommodating cavity, so that the plurality of vibration-damping particles in the accommodating cavity collide and rub against each other under the drive of the compressor, thereby reducing the vibration energy of the compressor, reducing the vibration energy transmitted by the compressor to the refrigerator body and other structures, and reducing the noise generated by the refrigerator.

[0067] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0068] Reference Figure 2 The embodiment of the present application provides a refrigerator, including a box and a compressor 100. The compressor 100 can be arranged in the box, and the compressor 100 can be used to suck in low-pressure refrigerant gas, compress and discharge high-pressure and high-temperature refrigerant gas, so as to reduce the temperature of the box by the heat absorbed in the process of cooling the high-pressure and high-temperature refrigerant gas, thereby providing a constant low-temperature state for the box containing food or other items.

[0069] Reference Figure 2-Figure 4 In some possible implementations, the refrigerator may include a vibration damper 200. The compressor 100 may be installed in the box through the vibration damper 200, so that the vibration energy of the compressor 100 can be absorbed by the vibration damper 200 to reduce the noise generated by the refrigerator.

[0070] The box body may be provided with a press support plate 300. The shock absorber 200 may be provided on the press support plate 300, and the surface of the shock absorber 200 facing away from the press support plate 300 may be used to connect the compressor 100, so that the compressor 100 may be connected to the press support plate 300 through the shock absorber 200, thereby reducing the vibration energy transmitted from the compressor 100 to the box body press support plate 300.

[0071] Exemplarily, the shock absorber 200 may include a body 210 . The surface of the body 210 facing the press pallet 300 may be fixedly connected to the press pallet 300 , and the surface of the body 210 facing away from the press pallet 300 may be connected to the compressor 100 , so that the compressor 100 may be connected to the press pallet 300 through the body 210 .

[0072] Reference Figure 3-Figure 5The main body 210 may be provided with a receiving cavity 214, and a plurality of movable damping particles 250 may be accommodated in the receiving cavity 214. When the compressor 100 is in operation, the compressor 100 may generate vibrations, and the compressor 100 transmits vibration energy to the plurality of damping particles 250 in the receiving cavity 214 through the main body 210. The plurality of damping particles 250 move in the receiving cavity 214, so that the plurality of damping particles 250 in the receiving cavity 214 collide and rub against each other under the drive of the compressor 100, thereby reducing the vibration energy of the compressor 100.

[0073] When the compressor 100 is placed vertically and the main body 210 is located below the compressor 100, the main body 210 may include a bottom plate 211 and a top plate 212 that are arranged parallel to each other in the vertical direction. The bottom plate 211 can at least be used to be fixedly connected to the press support plate 300 to fix the main body 210 to the press support plate 300. The top plate 212 can at least be used to be fixedly connected to the shell of the compressor 100 to fix the main body 210 to the compressor 100.

[0074] Reference Figure 4-Figure 6 The main body 210 may include a side wall 213. In the vertical direction, the bottom end of the side wall 213 is connected to the edge of the bottom plate 211, and the top end of the side wall 213 is connected to the edge of the top plate 212. The extension direction of the side wall 213 may be perpendicular to the plane where the top plate 212 or the bottom plate 211 is located. The bottom plate 211, the top plate 212 and the side wall 213 are jointly surrounded to form a receiving cavity 214, so that a plurality of vibration-damping particles 250 can be accommodated through the receiving cavity 214.

[0075] Exemplarily, the main body 210 may be configured as a square main body 210. In the square main body 210, the bottom plate 211 and the top plate 212 are both configured as squares, so that the structure of the main body 210 is more stable and the processing difficulty of the main body 210 is reduced.

[0076] The main body 210 can be connected to the compressor 100 through the square top plate 212, so that the compressor 100 can be placed in the middle of the top plate 212, thereby making the connection between the compressor 100 and the top plate 212 more stable. In addition, the main body 210 can be fixed to the press support plate 300 through the square bottom plate 211, thereby increasing the contact area between the main body 210 and the press support plate 300.

[0077] In the main body 210, the top plate 212, the bottom plate 211 and the side wall 213 can be connected and fixed in sequence by splicing or the like, so that the molding process of the main body 210 is more convenient and the assembly efficiency of the main body 210 is improved. Alternatively, at least two of the top plate 212, the bottom plate 211 and the side wall 213 can be integrally formed, so that the structure of the main body 210 is more stable and the possibility of deformation of the main body 210 is reduced.

[0078] Exemplarily, the body 210 may be a metal body 210 to improve the stability of the body 210 and reduce the possibility of deformation of the body 210. The thickness of at least one of the top plate 212, the bottom plate 211 and the side wall 213 may be greater than or equal to 0.5 mm and less than or equal to 1.5 mm.

[0079] For example, the thickness of the top plate 212, the bottom plate 211 and the side wall 213 may be set within any thickness range of 0.5 mm-0.8 mm, 0.8 mm-1 mm, 1 mm-1.2 mm, and 1.2 mm-1.5 mm.

[0080] When multiple vibration-damping particles 250 rub and collide with each other in the accommodating cavity 214, the vibration-damping particles 250 may generate friction and collision with the top plate 212, the bottom plate 211 and the side wall 213. The thickness of the top plate 212, the bottom plate 211 and the side wall 213 is greater than or equal to 0.5 mm, thereby reducing the possibility of deformation of the top plate 212, the bottom plate 211 and the side wall 213 and improving the stability of the main body 210.

[0081] The thickness of the top plate 212, the bottom plate 211 and the side wall 213 is less than or equal to 1.5 mm, thereby reducing the weight of the main body 210 while ensuring the rigidity and stability of the main body 210, reducing the manufacturing cost of the main body 210, and also making the installation process of the main body 210 more convenient.

[0082] It should be noted that the “thickness” is explained by taking the top plate 212 as an example. For example, the thickness of the top plate 212 can be set to be the thickness from the inner surface of the top plate 212 to the outer surface of the top plate 212, and the thickness direction of the top plate 212 is perpendicular to the plane where the top plate 212 is located. Alternatively, when the top plate 212 is set to be an arc-shaped top plate 212, the thickness direction of the arc-shaped top plate 212 can be perpendicular to the tangent direction of the arc-shaped top plate 212.

[0083] When the thickness of the top plate 212 is uneven at various locations, the thickness of the top plate 212 may be determined based on the average thickness of the top plate 212. Alternatively, the thickness of the top plate 212 may also be determined based on the minimum thickness of the top plate 212 or the maximum thickness of the top plate 212. Alternatively, the thickness of the top plate 212 may also be determined based on the thickness of the middle portion of the top plate 212.

[0084] In some possible implementations, the vibration-damping particles 250 may be configured as vibration-damping spherical particles. By using spherical particles as the vibration-damping particles 250, the surface area thereof can be increased, and the efficiency of the vibration-damping particles 250 in absorbing the vibration energy generated by the compressor 100 can be improved, thereby reducing the vibration energy generated by the compressor 100 from being transmitted to the refrigerator body.

[0085] Exemplarily, the particle size of the vibration-damping spheres may be greater than or equal to 0.5 mm and less than or equal to 2 mm. For example, the particle size of the vibration-damping spheres may be set within any particle size range of 0.5 mm-0.8 mm, 0.8 mm-1 mm, 1 mm-1.2 mm, 1.2 mm-1.5 mm, 1.5 mm-1.8 mm, and 1.8 mm-2 mm.

[0086] The particle size of the vibration-damping spheres is greater than or equal to 0.5 mm and less than or equal to 2 mm, so that the multiple vibration-damping spheres located in the accommodating cavity 214 can more easily collide and rub against each other, thereby improving the efficiency of the vibration-damping particles 250 in absorbing the vibration energy generated by the compressor 100.

[0087] And / or, illustratively, in the accommodation cavity 214, the filling rate of the damping particles 250 may be greater than or equal to 60% and less than or equal to 80%. The filling rate of the damping particles 250 may be set within any filling rate range of 60%-65%, 65%-70%, 70%-75%, and 75%-80%.

[0088] The filling rate of the vibration-damping particles 250 is greater than or equal to 60% and less than or equal to 80%, thereby ensuring the vibration-damping effect and stability of the vibration absorber 200, while avoiding overfilling or underfilling, ensuring that the vibration absorber 200 has sufficient elasticity and vibration-damping ability during operation, and improving the overall vibration-damping effect.

[0089] For example, the filling rate of the vibration-damping particles 250 is greater than or equal to 60%, thereby ensuring that more vibration-damping particles 250 can be accommodated in the accommodating cavity 214, thereby ensuring the vibration-damping effect and stability of the vibration absorber 200. The filling rate of the vibration-damping particles 250 is less than or equal to 80%, thereby ensuring the activity space of the vibration-damping particles 250 in the accommodating cavity 214, and reducing the possibility of the movement process of the vibration-damping particles 250 being restricted due to an excessive number of the vibration-damping particles 250.

[0090] It should be noted that the filling rate of the vibration-damping particles 250 can be determined according to the number or weight of the vibration-damping particles 250. For example, when the vibration-damping particles 250 fill the receiving cavity 214, the filling rate of the vibration-damping particles 250 can be set to 100%, and when the vibration-damping particles 250 do not fill the receiving cavity 214, the filling rate of the vibration-damping particles 250 is less than 100%, and a plurality of vibration-damping particles 250 can move in the receiving cavity 214 of the main body 210.

[0091] It is easy to understand that the main body 210 is set as a metal main body 210. Compared with the main body 210 being set as a rubber main body 210, the metal main body 210 can have better rigidity and stability. When the compressor 100 drives multiple vibration-damping particles 250 to collide and rub against each other through the main body 210, the deformation of the metal main body 210 is small, and the volume of the accommodating cavity 214 remains basically unchanged, thereby ensuring the activity space of the multiple vibration-damping particles 250 in the accommodating cavity 214.

[0092] In the accommodating cavity 214, the filling rate of the vibration-damping particles 250 is greater than or equal to 60% and less than or equal to 80%. When the main body 210 is set as a rubber main body 210, etc., the deformation of the rubber main body 210 is large, and the volume of the accommodating cavity 214 is prone to large changes, which makes the activity range of the vibration-damping particles 250 in the accommodating cavity 214 smaller, and the vibration-damping particles 250 are prone to limited movement, etc., which affects the vibration-damping effect of the vibration-damping particles 250.

[0093] Reference Figure 4-Figure 6 In some possible implementations, the main body 210 may be provided with a filling port 217. The filling port 217 may connect the inner and outer sides of the accommodating cavity 214, and the filling port 217 is at least used to put in or take out the vibration-damping particles 250, so as to make the process of filling the vibration-damping particles 250 into the accommodating cavity 214 more convenient.

[0094] Exemplarily, the filling port 217 may be disposed on the side wall 213 of the main body 210 , so that the position of the filling port 217 is more reasonable and the process of filling the damping particles 250 into the accommodating cavity 214 through the filling port 217 is more convenient.

[0095] The packing port 217 may be a packing threaded port, and the packing threaded port may be provided with internal threads. The shock absorber 200 may include a screw plug 2171, which is threadedly connected to the packing threaded port, and the screw plug 2171 may be used to at least close or open the packing threaded port.

[0096] When it is necessary to put the vibration-damping particles 250 into the accommodating cavity 214, the vibration-damping particles 250 can be put into the accommodating cavity 214 through the filling threaded opening. When the filling rate of the vibration-damping particles 250 in the accommodating cavity 214 reaches the required filling rate, the screw plug 2171 can be threadedly connected to the filling threaded opening, so that the filling threaded opening can be closed by the screw plug 2171, making the accommodating cavity 214 airtight.

[0097] Reference Figure 3 , Figure 7 and Figure 8In some possible implementations, the vibration absorber 200 may include a recessed portion 230. The recessed portion 230 may be disposed on a surface of the main body 210 that faces away from the box body, and the recessed portion 230 may be disposed on the top plate 212 of the main body 210. The recessed portion 230 may accommodate at least a portion of the compressor 100 to increase the contact area between the compressor 100 and the recessed portion 230, and improve the stability of the connection between the compressor 100 and the vibration absorber 200.

[0098] The recessed portion 230 may be connected to the top plate 212 of the main body 210 by welding or the like. Alternatively, the recessed portion 230 may be integrally provided with the top plate 212 of the main body 210, so that the connection between the recessed portion 230 and the top plate 212 of the main body 210 is more stable, and the possibility of deformation of the recessed portion 230, thereby affecting the stability of the main body 210, is reduced.

[0099] Exemplarily, the surface of the recessed portion 230 facing away from the bottom plate 211 may be provided with a vibration-damping connection layer 231. The surface of the vibration-damping connection layer 231 facing away from the recessed portion 230 may be connected to the compressor 100, so that the compressor 100 can be fixed relative to the recessed portion 230 through the vibration-damping connection layer 231.

[0100] Furthermore, when the compressor 100 is in operation, the compressor 100 can generate vibrations and transmit vibration energy to the recessed portion 230 through the vibration-damping connection layer 231 , and the vibration-damping connection layer 231 absorbs at least part of the vibration energy of the compressor 100 .

[0101] It should be noted that a layer of high damping material can be formed on the surface of the recessed portion 230 away from the bottom plate 211 by vulcanization or the like, and the high damping material can form a vibration-damping connection layer 231. The surface of the vibration-damping connection layer 231 away from the recessed portion 230 can also be connected to the housing of the compressor 100 by vulcanization or the like, so that the connection between the vibration-damping connection layer 231 and the housing of the compressor 100 is more stable.

[0102] Reference Figure 4-Figure 6 In some possible implementations, the shock absorber 200 may include a support frame 220. The support frame 220 may be disposed in the accommodating cavity 214, and the support frame 220 may be used to support at least one of the main body 210 and the recessed portion 230, thereby reducing the possibility of deformation of the main body 210 and the recessed portion 230, thereby improving the stability of the shock absorber 200.

[0103] Exemplarily, the support frame 220 can be fixedly connected to the main body 210. One end of the support frame 220 away from the main body 210 can be connected to the surface of the recessed portion 230 away from the vibration-damping connection layer 231, so that the recessed portion 230 can be supported by the support frame 220, reducing a large change in the volume of the accommodating cavity 214, and ensuring the activity space of the plurality of vibration-damping particles 250 in the accommodating cavity 214.

[0104] The support frame 220 may include a plurality of support portions, at least some of which may be arranged crosswise, or at least some of which may be arranged in a row.

[0105] Between the top plate 212 and the bottom plate 211, the portion of the support portion facing the bottom plate 211 can be fixedly connected to the bottom plate 211, one end of the partial support portion facing the top plate 212 can be fixed to the top plate 212, and one end of the remaining partial support portion facing the top plate 212 can be fixed to the recessed portion 230, thereby supporting the top plate 212 through the partial support portion, and supporting the recessed portion 230 through the partial support portion.

[0106] Alternatively, between the top plate 212 and the bottom plate 211, the portion of each support portion facing the bottom plate 211 can be fixedly connected to the bottom plate 211, the first portion of each support portion facing the top plate 212 can be fixed to the top plate 212, and the second portion of each support portion facing the top plate 212 can be fixed to the recessed portion 230, so that the top plate 212 and the recessed portion 230 can be supported by the support portions.

[0107] At least part of the support portion may be provided with a through hole 223 , and the through hole 223 may at least be used for the damping particles 250 to pass through, so that the damping particles 250 can rub and collide with each other in the accommodating cavity 214 , so that the vibration energy generated by the compressor 100 can be absorbed by the plurality of damping particles 250 .

[0108] For example, the number of the supporting parts can be set to two, and the two supporting parts can be cross-arranged. One of the supporting parts is set to the first supporting part 221, and the extension direction of the first supporting part 221 can be parallel to the width direction of the bottom plate 211. The other supporting part is set to the second supporting part 222, and the extension direction of the second supporting part 222 can be parallel to the length direction of the bottom plate 211. The middle part of the first supporting part 221 and the middle part of the second supporting part 222 can be cross-arranged.

[0109] The filling port 217 may be disposed on the side wall 213 of the main body 210, and the filling port 217 may be disposed on one side in the length direction of the bottom plate 211. The number of the filling ports 217 may be two, and the two filling ports 217 may include a first filling port 217 and a second filling port 217, and the first filling port 217 and the second filling port 217 may be disposed at intervals.

[0110] The first filling port 217 may be located at one side of the first support portion 221, and the first filling port 217 may face the first portion of the second support portion 222. The second filling port 217 may be located at the other side of the first support portion 221, and the second filling port 217 may face the second portion of the second support portion 222, and the first support portion 221 may be placed between the first filling port 217 and the second filling port 217.

[0111] In the first support portion 221 and the second support portion 222 , the first support portion 221 may be provided with a through opening 223 , while the second support portion 222 may not be provided with a through opening 223 , so that the first support portion 221 can separate the accommodating cavity 214 into two parts.

[0112] The two parts may be respectively configured as a first accommodating portion and a second accommodating portion. The first accommodating portion may be used to accommodate some of the damping particles 250 from the first filling port 217 , and the second accommodating portion may be used to accommodate some of the damping particles 250 from the second filling port 217 .

[0113] Some of the damping particles 250 in the first accommodation portion can move through the through opening 223 in the second support portion 222 , and some of the damping particles 250 in the second accommodation portion can move through the through opening 223 in the second support portion 222 .

[0114] In some possible implementations, the shock absorber 200 may be provided with a fixing bolt 215 , and the fixing bolt 215 may pass through the main body 210 .

[0115] The bolt head of the fixing bolt 215 can abut against the surface of the main body 210 facing away from the press plate 300 of the box body, and the threaded section of the fixing bolt 215 is penetrated through the press plate 300 of the box body. The threaded section of the fixing bolt 215 is threadedly connected to the press plate 300 of the box body, so that the shock absorber 200 can be fixed to the press plate 300 by the fixing bolt 215.

[0116] When the shock absorber 200 is relatively fixed to the press support plate 300 of the box body, the main body 210 of the shock absorber 200 can be placed on the press support plate 300 of the box body, with the recessed portion 230 of the shock absorber 200 facing away from the press support plate 300 of the box body, and then the fixing bolt 215 is passed through the main body 210 so that the bolt head of the fixing bolt 215 abuts against the surface of the main body 210 facing away from the press support plate 300, and the threaded section of the fixing bolt 215 is passed through the press support plate 300 of the box body, and the threaded section of the fixing bolt 215 is threadedly connected to the press support plate 300 of the box body, so that the shock absorber 200 can be relatively fixed to the box body by the fixing bolt 215.

[0117] Exemplarily, a protective tube 216 may be provided in the accommodating cavity 214, and the protective tube 216 may be close to the inner wall of the main body 210 to reduce the possibility of friction and collision between the vibration-damping particles 250 and the protective tube 216. The inner side of the protective tube 216 may be used to accommodate the fixing bolts 215, and the outer side of the protective tube 216 may be used to abut against the vibration-damping particles 250.

[0118] In this configuration, the protection tube 216 is close to the inner wall of the main body 210, reducing the interference of the protection tube 216 on the plurality of vibration-damping particles 250. The inner side of the protection tube 216 is used to accommodate the fixing bolts 215, and the outer side of the protection tube 216 is used to abut against the vibration-damping particles 250. When the compressor 100 is in operation, the plurality of vibration-damping particles 250 move in the accommodating cavity 214, and the protection tube 216 can play a certain role in isolating and blocking the vibration-damping particles 250 and the fixing bolts 215, reducing the possibility of the vibration-damping particles 250 directly hitting the fixing bolts 215.

[0119] Reference Figure 3 , Fig. 9 and Fig.10 In some embodiments of the present application, the compressor 100 may be disposed in the middle of the shock absorber 200, and the compressor 100 may have a plurality of support legs 110. The plurality of support legs 110 may be disposed around the outside of the recessed portion 230, and the support legs 110 face the surface of the main body 210 away from the box.

[0120] In this way, multiple support legs 110 are arranged around the outside of the recessed portion 230, and the support legs 110 are facing the surface of the main body 210 away from the box body, so that the center of gravity of the compressor 100 is closer to the recessed portion 230, making the connection between the compressor 100 and the recessed portion 230 more stable, reducing the possibility of the compressor 100 shaking relative to the recessed portion 230.

[0121] In some embodiments of the present application, a vibration-damping layer 240 is provided on the surface of the main body 210 facing away from the box. The material of the vibration-damping layer 240 can be the same as the material of the vibration-damping connecting layer 231. The bottom of the supporting foot 110 is fixedly connected to the surface of the main body 210 facing away from the box through the vibration-damping layer 240.

[0122] The bottom of the support foot 110 is fixedly connected to the surface of the main body 210 away from the box body through the vibration-damping layer 240, and the connection between the compressor 100 and the vibration absorber 200 is more stable. When the compressor 100 is in a working state, part of the vibration energy of the compressor 100 is transmitted to the main body 210 through the support foot 110 and the vibration-damping layer 240, so that part of the vibration energy can be absorbed by the vibration-damping layer 240;

[0123] The remaining vibration energy of the compressor 100 can be transmitted to the recessed portion 230 through the vibration-damping connecting layer 231. The vibration-damping connecting layer 231 absorbs at least part of the vibration energy of the compressor 100, so that the vibration-damping layer 240 and the vibration-damping connecting layer 231 can cooperate to further improve the absorption effect of the vibration energy of the compressor 100 and reduce the noise generated by the refrigerator.

[0124] Alternatively, in some possible implementations, the bottom of the support foot 110 may not be in contact with the main body 210 , and the surface of the vibration-damping connection layer 231 that is away from the recessed portion 230 may be in contact with the shell of the compressor 100 .

[0125] The bottom of the support foot 110 does not contact the main body 210, and the surface of the vibration-damping connecting layer 231 facing away from the recessed portion 230 is in contact with the shell of the compressor 100, so that the vibration energy of the compressor 100 is transmitted to the recessed portion 230 through the vibration-damping connecting layer 231, thereby reducing the possibility of collision and friction between the support foot 110 of the compressor 100 and the main body 210.

[0126] In summary, the refrigerator of the embodiment of the present application is provided with a vibration damper 200, and the compressor 100 can be installed in the box through the vibration damper 200. The vibration damper 200 includes a main body 210 and a recessed portion 230 connected to each other, and the main body 210 is provided with a receiving cavity 214, and the receiving cavity 214 accommodates a plurality of movable vibration damping particles 250. The recessed portion 230 is provided on the side of the main body 210 away from the box, and at least part of the compressor 100 can be provided in the recessed portion 230. The recessed portion 230 is provided with a vibration damping connection layer 231, and the surface of the vibration damping connection layer 231 away from the recessed portion 230 is connected to the compressor 100.

[0127] When the compressor 100 is in operation, the compressor 100 can generate vibrations and transmit vibration energy to the recessed portion 230 through the vibration-damping connection layer 231, and the vibration-damping connection layer 231 absorbs at least part of the vibration energy of the compressor 100. The compressor 100 transmits vibration energy to the plurality of vibration-damping particles 250 in the accommodating cavity 214 through the recessed portion 230 and the main body 210, and the plurality of vibration-damping particles 250 move in the accommodating cavity 214, so that the plurality of vibration-damping particles 250 in the accommodating cavity 214 collide and rub against each other under the drive of the compressor 100, thereby reducing the vibration energy of the compressor 100, reducing the vibration energy transmitted by the compressor 100 to the structure such as the cabinet of the refrigerator, and reducing the noise generated by the refrigerator.

The compressor 100 is installed in the box body through the shock absorber 200 . The shock absorber 200 includes a main body 210 , a recessed portion 230 and a support frame 220 .

[0129] The main body 210 is disposed in the box, and the main body 210 is provided with a receiving cavity 214, and a plurality of movable vibration-damping particles 250 are placed in the receiving cavity 214; a vibration-damping connecting layer 231 is provided on the surface of the recessed portion 230 away from the main body 210, and a support frame 220 is disposed in the receiving cavity 214, and the support frame 220 is at least used to support the recessed portion 230;

[0130] At least part of the compressor 100 is disposed in the recessed portion 230, and the compressor 100 is connected to the recessed portion 230 via a vibration-damping connecting layer 231; when the compressor 100 is in working state, the vibration-damping connecting layer 231 absorbs at least part of the vibration energy of the compressor 100, and the multiple vibration-damping particles 250 located in the accommodating cavity 214 collide and rub against each other under the drive of the compressor 100 to reduce the vibration energy of the compressor 100.
