[0002] A refrigerator is a common household appliance that can keep food ingredients or other items at a constant low temperature. The refrigerator includes a box body, a vacuum pump and a fresh-keeping drawer arranged in the box body. The vacuum pump can pump air out of the fresh-keeping drawer so that the fresh-keeping drawer forms a receiving space in a negative pressure state, and thus the food ingredients can be stored by using the receiving space in the negative pressure state. However, when the vacuum pump pumps air out of the fresh-keeping drawer, noise is easily generated, resulting in a large noise of the refrigerator. Utility Model Content

[0003] The embodiments of the present application provide a refrigerator, which can solve the technical problem that when the vacuum pump pumps air out of the fresh-keeping drawer, noise is easily generated, resulting in a large noise of the refrigerator.

[0004] In a first aspect, the embodiments of the present application provide a refrigerator, including:

[0005] A box body;

[0006] A fresh-keeping drawer arranged in the box body;

[0007] An installation structure including a damping sleeve and a fixing member; the damping sleeve is fixedly connected to the box body through the fixing member, the damping sleeve is provided with a receiving cavity, and a contact portion arranged in the receiving cavity;

[0008] A vacuum pump fixedly connected to the box body through the installation structure, and an air inlet of the vacuum pump is communicated with the fresh-keeping drawer; the vacuum pump is arranged in the receiving cavity, and a housing of the vacuum pump abuts against the contact portion.

[0009] In the refrigerator according to the embodiments of the present application, the housing of the vacuum pump abuts against the contact portion of the damping sleeve. The vibration generated by the vacuum pump is first transmitted to the contact portion, then from the contact portion to the receiving cavity of the damping sleeve, and then transmitted to the box body through the damping sleeve. During this process, the elastic deformation generated by the contact portion can reduce the transmission of vibration energy, and thus the noise generated by the vacuum pump due to vibration can be reduced. Therefore, the damping sleeve can absorb the vibration energy generated by the vacuum pump and reduce the noise of the refrigerator. With such a setting, the use experience of the product can be improved, and thus the quality of life of the user can be improved.

[0010] Long-term vibration of the vacuum pump may cause the internal parts thereof to become loose or damaged. The vacuum pump is arranged in the receiving cavity, and the damping sleeve can absorb the vibration energy generated by the vacuum pump, thereby reducing the vibration amplitude of the vacuum pump. The use of the damping sleeve can extend the service life of the vacuum pump and improve the reliability of the refrigerator.

[0011] In some embodiments of the present application, the number of the contact portions is set to be multiple;

[0012] The plurality of abutting portions are sequentially arranged on the inner wall of the accommodating chamber around the extending direction of the accommodating chamber, and the plurality of abutting portions abut against the outer peripheral surface of the housing of the vacuum pump.

[0013] Such an arrangement can ensure that the vacuum pump and the abutting portion are subjected to uniform force when abutting against each other, thereby increasing the service life of the vacuum pump.

[0014] In some embodiments of the present application, the abutment portion is configured as a flexible abutment portion.

[0015] The abutment portion is configured as a flexible abutment portion, which can effectively absorb the vibration generated when the vacuum pump is working, reduce the noise of the vacuum pump, and improve the user experience.

[0016] The abutment portion may be a flexible abutment portion, which can prevent the vacuum pump from falling out of the vibration-damping sleeve and improve the working stability of the vacuum pump.

[0019] Such an arrangement can prevent the abutment portion from being cracked or damaged at the end connected to the inner wall of the accommodating cavity, thereby improving the reliability of the vibration-damping sleeve.

[0020] In some embodiments of the present application, a fixing groove is formed between two adjacent abutting portions, and the fixing groove is at least used to accommodate at least a portion of the vacuum pump.

[0021] The heat generated by the vacuum pump when it is working can be dissipated outside the accommodating cavity along the multiple fixed grooves, thereby improving the life and reliability of the vacuum pump.

[0022] In some embodiments of the present application, the vibration-damping sleeve is provided with a limiting portion, the limiting portion closes at least a portion of the accommodating cavity, and an opening is formed at one end of the accommodating cavity away from the limiting portion;

[0023] The vacuum pump moves into or out of the accommodating chamber through the opening; when the vacuum pump is located in the accommodating chamber, one end of the vacuum pump facing away from the opening abuts against the limiting portion.

[0024] With this arrangement, the air intake and outlet of the vacuum pump are unobstructed, which facilitates air flow, improves the working efficiency of the vacuum pump, and helps to extend the shelf life of food.

[0025] The air intake and outlet of the vacuum pump need to be connected to pipelines, and the vacuum pump is provided with openings to facilitate operations such as pipe plugging.

[0026] In some embodiments of the present application, the damping sleeve is provided with an installation part, and the installation part is provided with an installation opening;

[0027] The fixing member includes a fixing column and a fixing bolt; the fixing column is inserted into the installation opening, the fixing bolt is inserted into the fixing column, and the fixing bolt is threadedly connected to the box body.

[0028] The fixing column is inserted into the installation opening, and after the fixing bolt passes through the fixing column, it is threadedly connected to the box body. In this way, when tightening the fixing bolt, it is not necessary to align the fixing member with the installation opening of the damping sleeve, which can reduce the operation difficulty.

[0029] The installation opening can reduce the vibration energy of the vacuum pump during operation from being transmitted to the fixing member and then to the box body, affecting the reliability of the refrigerator.

[0030] In some embodiments of the present application, the installation part is provided with a plurality of elastic bumps, the plurality of elastic bumps are arranged in a ring around the outside of the fixing bolt, and the installation part abuts against the fixing member through the plurality of elastic bumps.

[0031] The fixing member elastically deforms through the elastic bumps to reduce the vibration energy transmitted during the operation of the vacuum pump, improve the reliability of the fixing member, and can avoid vibration effects on other components of the refrigerator.

[0032] In some embodiments of the present application, the damping sleeve is provided with a plurality of fixing ribs, the plurality of fixing ribs are arranged in sequence along the extending direction of the accommodating cavity, and the fixing ribs extend along the circumferential direction of the damping sleeve;

[0033] For example, the damping sleeve being provided with a plurality of fixing ribs is beneficial to improving the strength of the damping sleeve.

[0034] In a second aspect, an embodiment of the present application provides a refrigerator including a box body, and a fresh-keeping drawer, a vacuum pump, and an installation structure arranged in the box body;

[0036] When the vacuum pump is in a working state, the damping sleeve is used to absorb the vibration energy generated by the vacuum pump to reduce the noise generated by the vacuum pump.

[0037] In the refrigerator according to the embodiment of the present application, the housing of the vacuum pump abuts against the abutting part of the damping sleeve. The vibration generated by the vacuum pump is first transmitted to the abutting part, then from the abutting part to the accommodating cavity of the damping sleeve, and then transmitted to the box body through the damping sleeve. During this process, the elastic deformation generated by the abutting part can reduce the transmission of vibration energy, and thus the noise generated by the vacuum pump due to vibration can be reduced. Therefore, the damping sleeve can absorb the vibration energy generated by the vacuum pump and reduce the noise of the refrigerator. With such a setting, the use experience of the product can be improved, and thus the quality of life of the user can be improved.

[0057] As described in the background art, in the related art, a refrigerator includes a box body, a vacuum pump and a fresh-keeping drawer disposed in the box body. The vacuum pump can evacuate the fresh-keeping drawer to form a containing space in a negative pressure state, reduce the oxygen content in the containing space of the fresh-keeping drawer, and thus can use the containing space in the negative pressure state to store food materials or extend the shelf life of food materials.

[0058] However, during the air extraction process of the vacuum pump, rapid air flow movement will be generated. When these air flows pass through various channels and components inside the pump body of the vacuum pump, friction, impact, etc. may occur, thus generating noise. Moreover, when the vacuum pump is running, components such as the internal motor and bearing of the vacuum pump will generate mechanical vibrations, or when the vacuum pump vibrates, it will rub and collide with the box body of the refrigerator to generate vibrations. These vibrations will be transmitted to the box body connected to the vacuum pump, resulting in high noise of the refrigerator.

[0059] In view of this, in the refrigerator according to the embodiment of the present application, the housing of the vacuum pump abuts against the abutting portion of the shock-absorbing sleeve. The vibration generated by the vacuum pump is first transmitted to the abutting portion, then from the abutting portion to the accommodating cavity of the shock-absorbing sleeve, and then transmitted to the box body through the shock-absorbing sleeve. During this process, the elastic deformation generated by the abutting portion can reduce the transmission of vibration energy, and further reduce the noise generated by the vacuum pump due to vibration. Therefore, the shock-absorbing sleeve can absorb the vibration energy generated by the vacuum pump and reduce the noise of the refrigerator. Such a setting can improve the use experience of the product, and further improve the quality of life of users.

[0060] Long-term vibration of the vacuum pump may cause the internal parts to loosen or be damaged. The vacuum pump is disposed in the accommodating cavity, and the shock-absorbing sleeve can absorb the vibration energy generated by the vacuum pump, thereby reducing the vibration amplitude of the vacuum pump. The use of the shock-absorbing sleeve can extend the service life of the vacuum pump and improve the reliability of the refrigerator.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0067] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0068] Referring to Figure 1 As shown, an embodiment of the present application provides a refrigerator, including a cabinet 100. The cabinet 100 provides support for the refrigerator and protects the internal components, and the cabinet 100 can also provide a space for storing food ingredients.

[0069] Exemplarily, the cabinet 100 generally includes parts such as an outer shell, an inner liner, and a door body. The outer shell is the outermost layer of the refrigerator, responsible for protecting the internal equipment and heat insulation. The inner liner is the internal space of the refrigerator, used for storing food ingredients and beverages. The door body is used to enclose the internal space of the refrigerator to prevent cold air leakage.

[0070] In some possible implementation manners, the refrigerator may include a storage space (not shown in the figure), and the storage space is located inside the cabinet 100. The storage space is the space inside the refrigerator for storing food ingredients that need to be refrigerated or frozen. The storage space can extend the shelf life of food and keep it fresh. The storage space of the refrigerator generally includes a refrigerating chamber and a freezing chamber.

[0071] In some possible implementation manners, the refrigerator may include a refrigeration system (not shown in the figure), and the refrigeration system can at least be used to supply cold air into the storage space. The refrigeration system includes a compressor, a condenser, a throttle valve, and an evaporator. The refrigerant circulates through the components in the refrigeration system to achieve the refrigeration effect.

[0072] The compressor is one of the core components of the refrigerator, responsible for compressing the refrigerant from low-pressure gas state into high-pressure gas state. In this process, the temperature and pressure of the refrigerant will both increase.

[0073] The condenser is usually located at the back or bottom of the refrigerator. The condenser can cool and condense the high-temperature and high-pressure gaseous refrigerant discharged by the compressor into a liquid state. This process is usually achieved through heat exchange. After being condensed by the condenser, the temperature of the refrigerant decreases, but the pressure is still relatively high.

[0074] The throttle valve can quickly reduce the pressure of the high-pressure liquid refrigerant. The throttle valve adjusts the refrigerating capacity of the refrigeration system by controlling the flow rate of the refrigerant.

[0075] The evaporator absorbs heat to change the refrigerant from a liquid state to a gas state, thereby reducing the temperature inside the refrigerator.

[0076] Exemplarily, the main flow process of the refrigerant in each component is as follows: The refrigerant enters the condenser after passing through the compressor, enters the throttle valve after passing through the condenser, enters the evaporator after passing through the throttle valve, and returns to the compressor after passing through the evaporator.

[0077] The compressor compresses the refrigerant gas in a low-pressure and low-temperature state to form a high-temperature and high-pressure gas. Subsequently, the compressor discharges the compressed refrigerant gas, and the discharged refrigerant gas flows into the condenser. Then, the condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process. Next, the throttle valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state in the condenser into a low-pressure liquid-phase refrigerant. Finally, the evaporator evaporates the refrigerant expanded in the throttle valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can utilize the heat exchange of the refrigerant to achieve the refrigeration effect.

[0078] In some possible embodiments, the refrigerator may include a seal and thermal insulation material (not shown in the figure) to ensure effective sealing when the door is closed and prevent cold air leakage.

[0079] In some possible embodiments, the refrigerator may include a thermostat and a control panel (not shown in the figure) to achieve the functions of setting and adjusting the temperatures of the refrigerating chamber and the freezing chamber.

[0080] Continue to refer to Figure 1 As shown, the refrigerator according to the embodiment of the present application may include a fresh-keeping drawer 200, and the fresh-keeping drawer 200 can extend the fresh-keeping time of food materials. The fresh-keeping drawer 200 is disposed inside the cabinet 100. Specifically, the fresh-keeping drawer 200 may be disposed in the refrigerating chamber of the refrigerator. For example, the fresh-keeping drawer 200 is usually designed with a slide rail, and the slide rail enables the fresh-keeping drawer 200 to be smoothly pulled out and pushed in, facilitating the taking and placing of food materials.

[0081] The fresh-keeping drawer 200 can extend the fresh-keeping time of food materials by controlling the humidity, and the user can adjust the humidity inside the fresh-keeping drawer 200 according to the type of food materials stored. For example, a higher humidity is suitable for storing leafy vegetables, and a lower humidity is suitable for storing fruits.

[0082] The fresh-keeping drawer 200 can extend the fresh-keeping time of food materials by controlling the temperature, and the temperature inside the fresh-keeping drawer 200 can be adjusted according to the needs of different food materials. For example, the fresh-keeping drawer 200 can be set to a low temperature close to 0°C for storing meats and fishes.

[0083] The fresh-keeping drawer 200 can extend the fresh-keeping time of food materials by antibacterial and deodorizing methods. The fresh-keeping time of food materials is extended by inhibiting the growth of bacteria and molds inside the fresh-keeping drawer 200.

[0084] The fresh-keeping drawer 200 can extend the fresh-keeping time of food materials by reducing oxygen. By extracting the air inside the fresh-keeping drawer 200 to reduce the oxygen inside the fresh-keeping drawer 200, most bacteria and molds are difficult to grow and reproduce in an oxygen-deficient environment, and the spoilage of food materials can be delayed.

[0085] Referring to Figure 2 and Figure 3 As shown, the refrigerator according to the embodiment of the present application may include a vacuum pump 400. The vacuum pump 400 can use its own motor to drive the centrifugal impeller to rotate at a high speed, generating a negative pressure area to extract the air inside the refrigerator. The vacuum pump 400 is provided with a housing, and the housing of the vacuum pump 400 is used to protect the motor and impeller and other parts inside the vacuum pump 400 from being damaged.

[0086] The vacuum pump 400 may include an air inlet 410. For the convenience of description, the end of the vacuum pump 400 provided with the air inlet 410 is defined as the front end of the vacuum pump 400, and the end of the vacuum pump 400 facing away from the air inlet 410 is defined as the rear end of the vacuum pump 400. The air inlet 410 at the front end of the vacuum pump 400 is communicated with the fresh-keeping drawer 200. The vacuum pump 400 extracts the air inside the fresh-keeping drawer 200 through the air inlet 410, so that a negative pressure area is formed in the fresh-keeping drawer 200 to reduce the oxygen inside the fresh-keeping drawer 200 and extend the fresh-keeping time of the food materials.

[0087] In some embodiments, the vacuum pump 400 may include an air outlet 420, and the air outlet 420 is also located at the front end of the vacuum pump 400. The air outlet 420 sends the air extracted by the vacuum pump 400 to the muffler and then discharges the air out of the refrigerator. The vacuum pump 400 will generate a relatively high noise during operation. By connecting the air outlet 420 with the muffler, the size of the reduced noise can be achieved.

[0088] In some embodiments, the refrigerator may include a pressure relief device (not shown in the figure). The vacuum pump 400 extracts the air inside the fresh-keeping drawer 200 to form a negative pressure area in the fresh-keeping drawer 200. And the pressure relief device can break the negative pressure area so that the fresh-keeping drawer 200 can be easily opened, facilitating the taking of food materials.

[0089] Referring to Figure 4 and Figure 5 As shown, the refrigerator according to the embodiment of the present application may include a mounting structure 300. Through the mounting structure 300, the vacuum pump 400 can be fixedly connected to the cabinet 100. For example, the vacuum pump 400 can be fixed at a position on one side of the inside of the cabinet 100 close to the fresh-keeping drawer 200 and on the back of the cabinet 100. In this way, the distance between the vacuum pump 400 and the fresh-keeping drawer 200 can be reduced, and the speed of the vacuum pump 400 extracting the air inside the fresh-keeping drawer 200 is relatively fast, which is beneficial to the fresh-keeping of food materials.

[0090] The installation structure 300 includes a vibration damping sleeve 310 and a fixing member 320. The vibration damping sleeve 310 is fixedly connected to the box body 100 through the fixing member 320, and the vibration damping sleeve 310 is used to fix the vacuum pump 400 on the box body 100. The vibration damping sleeve 310 is used to absorb the vibration energy generated by the vacuum pump 400. For example, the vibration damping sleeve 310 can be made of rubber material, and the rubber material has good elasticity and wear resistance, which can meet the usage requirements of the vibration damping sleeve 310.

[0091] Among them, the fixing member 320 includes a fixing post 321 and a fixing bolt. The fixing post 321 is arranged at a suitable position of the fixing member 320, and the fixing post 321 is a hollow cylindrical shape. The fixing bolt can pass through the fixing post 321 and fix the fixing member 320 on the box body 100 through threaded connection with the box body 100.

[0092] Refer to Figure 5 、 Figure 6 and Figure 7 As shown, specifically, the vibration damping sleeve 310 is provided with a receiving cavity 311 and a contact portion 312 arranged in the receiving cavity 311. Among them, the receiving cavity 311 can be a hollow cylindrical-like cavity, and the vacuum pump 400 is arranged in the receiving cavity 311. The contact portion 312 protrudes from the receiving cavity 311, and the housing of the vacuum pump 400 abuts against the contact portion 312. The vacuum pump 400 is restricted in the receiving cavity 311 by the contact portion 312 of the vibration damping sleeve 310.

[0093] When the vacuum pump 400 is in a working state, the vibration generated by the vacuum pump 400 is first transmitted to the contact portion 312, then from the contact portion 312 to the receiving cavity 311 of the vibration damping sleeve 310, and then transmitted to the box body 100 through the vibration damping sleeve 310. The housing of the vacuum pump 400 abuts against the contact portion 312 of the vibration damping sleeve 310, and a part of the vibration generated by the vacuum pump 400 can be eliminated through the contact portion 312, thereby reducing the noise generated by the vacuum pump 400. Therefore, the vibration damping sleeve 310 can absorb the vibration energy generated by the vacuum pump 400 and reduce the noise of the refrigerator. Such a setting can improve the usage experience of the product and thus improve the quality of users' lives.

[0094] Long-term vibration of the vacuum pump 400 may cause the internal parts to loosen or be damaged. The vacuum pump 400 is arranged in the receiving cavity 311, and the vibration damping sleeve 310 can absorb the vibration energy generated by the vacuum pump 400, thereby reducing the vibration amplitude of the vacuum pump 400. The use of the vibration damping sleeve 310 can extend the service life of the vacuum pump 400 and improve the reliability of the refrigerator.

[0095] Refer to Figure 6 and Figure 7As shown, the number of abutting portions 312 of the shock-absorbing sleeve 310 is set to be multiple, and the multiple abutting portions 312 are arranged on the inner wall of the accommodating cavity 311. The multiple abutting portions 312 abut against the outer peripheral surface of the housing of the vacuum pump 400. The multiple abutting portions 312 are evenly distributed around the accommodating cavity 311, so that the force on the vacuum pump 400 and the abutting portions 312 is uniform when they abut, and the service life of the vacuum pump 400 is improved.

[0096] The shock-absorbing sleeve 310 can be provided with six abutting portions 312, and the six abutting portions 312 are evenly distributed on the inner wall of the accommodating cavity 311. When the vacuum pump 400 is assembled with the shock-absorbing sleeve 310, the operation is easy and the force on the vacuum pump 400 is uniform.

[0097] Furthermore, the abutting portion 312 is set as a flexible abutting portion. For example, the shock-absorbing sleeve 310 can be made of rubber, and the abutting portion 312 can be a flexible abutting portion. Or, the abutting portion 312 can be processed by processes such as vulcanization and nano-injection molding.

[0098] When the flexible abutting portion abuts against the vacuum pump 400, elastic deformation can occur, which can absorb the vibration generated when the vacuum pump 400 works, thereby reducing the noise of the vacuum pump 400 and improving the user experience.

[0099] The flexible abutting portion tightly abuts against the housing of the vacuum pump 400 by elastic deformation. When the vacuum pump 400 works, vibration will be generated, and the vacuum pump 400 may come out of the shock-absorbing sleeve 310. The abutting portion 312 can be a flexible abutting portion, and the friction force between the abutting portion 312 and the outer shell of the vacuum pump 400 is large, which can prevent the vacuum pump 400 from coming out of the shock-absorbing sleeve 310 and improve the working stability of the vacuum pump 400.

[0100] Refer to Figure 7 As shown, for the convenience of description, in the plane perpendicular to the extending direction of the abutting portion 312, the end of the abutting portion 312 facing the housing of the vacuum pump 400 is defined as the first end of the abutting portion 312. The end of the abutting portion 312 connected to the inner wall of the accommodating cavity 311 is defined as the second end of the abutting portion 312. In the direction from the first end to the second end of the abutting portion 312, the cross-sectional area of the abutting portion 312 gradually decreases. That is to say, in the plane perpendicular to the extending direction of the abutting portion 312, the side surface of the abutting portion 312 is approximately trapezoidal. Cracks or damages are likely to occur at the end where the abutting portion 312 is connected to the inner wall of the accommodating cavity 311. Such a setting can reduce the occurrence of cracks or damages and improve the reliability of the shock-absorbing sleeve 310.

[0101] A plurality of abutting portions 312 are provided on the inner wall of the accommodating cavity 311, and a fixing groove 313 is formed between two adjacent abutting portions 312. The plurality of abutting portions 312 are evenly distributed on the inner wall of the accommodating cavity 311, and the fixing grooves 313 are evenly distributed on the inner wall of the accommodating cavity 311. The heat generated when the vacuum pump 400 operates can be dissipated to the outside of the accommodating cavity 311 along the plurality of fixing grooves 313, thereby increasing the service life of the vacuum pump 400.

[0102] When the vacuum pump 400 abuts against the abutting portion, elastic deformation may occur, and the fixing groove 313 can accommodate at least a part of the vacuum pump 400.

[0103] Refer to Figure 8 As shown, as described above, the accommodating cavity 311 can be a hollow cylindrical-like cavity. The extending direction of the columnar shape of the accommodating cavity 311 is defined as the extending direction N of the accommodating cavity 311. The abutting portion 312 extends along the extending direction N of the accommodating cavity 311, and the extending direction of the abutting portion 312 is arranged parallel to the extending direction of the accommodating cavity 311. Such an arrangement increases the contact area between the abutting portion 312 and the vacuum pump 400, and can prevent the vacuum pump 400 from disengaging from the damping sleeve 310.

[0104] Refer to Figure 9 As shown, the damping sleeve 310 is provided with a limiting portion 314, and the limiting portion 314 is used to limit the movement of the vacuum pump 400 in the direction away from the extending direction N, thereby restricting the vacuum pump 400 from disengaging from the damping sleeve 310.

[0105] In some embodiments, the limiting portion 314 can completely enclose the accommodating cavity 311. When the vacuum pump 400 operates, vibrations are generated to prevent the vacuum pump 400 from disengaging from the damping sleeve 310.

[0106] In other embodiments, the limiting portion 314 encloses a part of the accommodating cavity 311. In other words, there is a gap between the limiting portion 314 enclosing a small part of the accommodating cavity 311. Heat will be generated when the vacuum pump 400 operates, and the heat can be dissipated from the gap of the limiting portion 314, extending the service life of the vacuum pump 400 and improving the reliability of the vacuum pump 400. Moreover, it can be observed whether the vacuum pump 400 is properly installed at the gap of the limiting portion 314.

[0107] Refer to Figure 10 As shown, an opening 315 is formed at one end of the accommodating cavity 311 facing away from the limiting portion 314. The opening 315 has no obstruction, and the vacuum pump 400 is moved into or out of the accommodating cavity 311 through the opening 315.

[0108] After the vacuum pump 400 is moved into the accommodation cavity 311 through the opening 315, the rear end of the vacuum pump 400 abuts against the limiting part 314. The front end of the vacuum pump 400 is located near the opening 315 of the accommodation cavity 311, and the suction port 410 and the air outlet of the vacuum pump 400 are unobstructed, facilitating air flow, improving the working efficiency of the vacuum pump 400, and being beneficial to extending the fresh-keeping time of food materials.

[0109] In some embodiments, pipelines need to be connected to the suction port 410 and the air outlet 420 of the vacuum pump 400. The opening 315 is provided on the vacuum pump 400 to facilitate operations such as pipeline connection.

[0110] Refer to Figure 11 As shown, the damping sleeve 310 is provided with an installation part 316. The damping sleeve 310 can be fixed to the box body 100 through the installation part 316. The installation part 316 is arranged on both sides perpendicular to the extension direction N of the accommodation cavity 311. Such an arrangement can ensure that the damping sleeve 310 is firmly fixed to the box body 100, reduce the vibration generated by the vacuum pump 400, and reduce the noise of the refrigerator.

[0111] The installation part 316 is provided with an installation opening 3160. The installation opening 3160 is arranged at the central position of the installation part 316 to facilitate tightening the fixing bolt. As described above, the fixing member 320 includes a fixing column 321 and a fixing bolt. The fixing column 321 passes through the installation opening 3160, and after the fixing bolt passes through the fixing column 321, it is threadedly connected to the box body 100. In this way, when tightening the fixing bolt, it is not necessary to align the fixing member 320 with the installation opening 3160 of the damping sleeve 310, which can reduce the operation difficulty.

[0112] Furthermore, the installation opening 3160 can be set to be circular to facilitate the passing of the fixing column 321. The installation opening 3160 can also be set as a circular hole, and the inner surface is provided with a plurality of protrusions, which can reduce the transmission of vibration energy from the vacuum pump 400 during operation to the fixing member 320, and then to the box body 100, affecting the reliability of the refrigerator.

[0113] The installation part 316 is provided with a plurality of elastic bumps 3161. The installation part 316 abuts against the fixing member 320 through the plurality of elastic bumps 3161. That is to say, the damping sleeve 310 abuts against the fixing member 320 through the plurality of elastic bumps 3161. The fixing member 320 undergoes elastic deformation through the elastic bumps 3161 to reduce the vibration energy transmitted during the operation of the vacuum pump 400, improve the reliability of the fixing member 320, and can avoid generating vibration effects on other components of the refrigerator.

[0114] The plurality of elastic bumps 3161 are evenly arranged in a ring outside the installation opening 3160. That is to say, the plurality of elastic bumps 3161 are evenly arranged in a ring outside the fixing bolt, improving the reliability of the fixing member 320.

[0115] Specifically, the installation part 316 is provided with six elastic bumps 3161, which saves the material of the damping sleeve 310 and reduces the weight of the damping sleeve 310 under the condition of meeting the use requirements.

[0116] Referring to Figure 11 and Figure 12 As shown, the damping sleeve 310 is provided with fixing ribs 317. The fixing ribs 317 are beneficial to improving the strength of the damping sleeve 310, making the vacuum pump 400 more firm and stable when pumping air. The fixing ribs 317 extend along the circumferential direction of the damping sleeve 310. In other words, the direction of the fixing ribs 317 is arranged along the direction connecting the installation parts 316 on both sides of the accommodating cavity 311. The fixing ribs 317 can effectively disperse and transfer the load in the area of the installation part 316, making the damping sleeve 310 more stable when stressed.

[0117] The damping sleeve 310 is provided with a plurality of fixing ribs 317. The plurality of fixing ribs 317 are arranged in sequence along the extending direction N of the accommodating cavity 311, further improving the strength of the damping sleeve 310.
