Description

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] Refrigerators are common household appliances that keep food and other items at a constant low temperature. They consist of a refrigerator, a vacuum pump, and a low-pressure fresh-keeping drawer. The vacuum pump evacuates air from the drawer, creating a negative pressure storage space, allowing food to be stored there. However, vacuum pump installation is cumbersome and inefficient. Utility Model Content

[0003] The embodiment of the present application provides a refrigerator that can solve the technical problems of complicated installation process of a vacuum pump and low installation efficiency of the vacuum pump.

[0004] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0005] A box body, wherein the box body is formed with a refrigeration compartment;

[0006] a refrigeration system, connected to the refrigeration compartment and supplying cold air to the refrigeration compartment;

[0007] A box liner is provided in the refrigeration room; a mounting portion is provided on the rear side of the box liner, the mounting portion is protruding relative to the box liner, and the mounting portion is located on one side of the center line of the box liner;

[0008] A low-pressure fresh-keeping drawer is movably arranged in the box liner; when the low-pressure fresh-keeping drawer is located in the box liner, the low-pressure fresh-keeping drawer and the box liner together form an accommodating space;

[0009] Vacuum pump assembly, including:

[0010] a fixing assembly, the fixing assembly being arranged on the mounting portion;

[0011] A shock-absorbing sleeve, the shock-absorbing sleeve being connected to the box through the fixing assembly, and the shock-absorbing sleeve being provided with an accommodating cavity;

[0012] A vacuum pump is arranged in the accommodating cavity; the air intake of the vacuum pump is provided with an air intake pipe, the air intake pipe passes through the box and is used to communicate with the accommodating space.

[0013] By installing the vacuum pump in a shock-absorbing sleeve and connecting it with a fixing component, the installation process of the vacuum pump is simplified and the installation efficiency is improved; the design of the shock-absorbing sleeve effectively reduces the vibration generated by the vacuum pump during operation, thereby reducing noise and improving the user experience; the vacuum pump is connected to the storage space of the low-pressure fresh-keeping drawer through an air suction pipe, which can effectively extract air and form a negative pressure environment, which helps to extend the shelf life of food and maintain the freshness of food.

[0014] In some embodiments of the present application, the air outlet of the box is located at the mounting portion;

[0015] The air intake duct is connected to the mounting portion, and the air intake duct is communicated with the accommodating space through an air outlet of the box.

[0016] In some embodiments of the present application, the fixing assembly includes:

[0017] A first fixing member and a second fixing member, the shock-absorbing sleeve is accommodated between the first fixing member and the second fixing member, and at least one of the first fixing member and the second fixing member is connected to the box.

[0018] The vacuum pump assembly is directly mounted on the refrigerator liner, shortening the distance between the vacuum pump and the accommodating space. Compared with mounting the vacuum pump on the air duct assembly of the refrigerator's refrigeration system, shorter pipes can be used, thereby reducing costs. At the same time, the shorter pipes, as a whole, avoid relative movement when mounted on the refrigerator liner, thereby avoiding the risk of pipe extrusion.

[0019] The vacuum pump is mounted on the rear side of the liner. When the vacuum pump draws air from the liner through the suction pipe located in the mounting portion, negative pressure is created inside the liner, causing local deformation of the liner. This mounting portion improves the strength of the liner at the corresponding location, reducing the likelihood of deformation of the liner at the suction pipe, thereby reducing the possibility of the vacuum pump being squeezed by the deformation of the liner.

[0020] At the same time, this arrangement also facilitates the installation and maintenance of the vacuum pump. Users or maintenance personnel can easily access and operate the vacuum pump components, reducing the time and complexity of installation and maintenance. The fixed components are placed on the rear side of the cabinet, which helps to better utilize the internal space of the refrigerator and avoids occupying too much front or side space, thereby not affecting the layout of other functional components.

[0021] The fixed component and the box body are connected in a detachable manner, which allows the vacuum pump component to be easily removed and reinstalled when needed, simplifying the maintenance and replacement process; through the fixed position and detachable design of the above-mentioned vacuum pump component, the shock-absorbing sleeve and the fixed component can effectively isolate and reduce vibration transmission, further reducing the noise during the operation of the vacuum pump.

[0022] In some embodiments of the present application, the first fixing member faces toward the box liner, and the second fixing member is away from the box liner;

[0023] The fixing assembly further includes a connecting portion and a buckling fixing portion, the first fixing member and the second fixing member are connected via the buckling fixing portion, and the first fixing member and the second fixing member are connected to the box liner via the connecting portion.

[0024] By accommodating the shock-absorbing sleeve between the first fixing member and the second fixing member, the installation process of the vacuum pump is simplified; the design of the fixing assembly makes the installation process more intuitive and efficient; the use of the shock-absorbing sleeve effectively absorbs and isolates the vibration generated by the vacuum pump during operation, thereby reducing noise and improving the user experience of the refrigerator, especially when a quiet environment is required; at least one of the first fixing member and the second fixing member is connected to the box body, ensuring the stability of the fixing assembly while providing flexibility for easy installation and maintenance; the structural design of the first fixing member and the second fixing member provides additional support and stability, ensuring that the vacuum pump remains stable and not easy to shift during operation.

[0025] In some embodiments of the present application, there are multiple connecting parts, each of which passes through the first fixing member and / or the second fixing member, and is connected to the box.

[0026] The snap-fit ​​fixing portion passes through the first fixing member and the second fixing member, and the snap-fit ​​fixing portion connects the first fixing member and the second fixing member together, which can provide additional support and fixing; multiple connecting parts can provide support and fixation at multiple points, thereby enhancing the overall stability of the fixing assembly, effectively resisting vibration and displacement, and ensuring the stability of the vacuum pump during operation; through the design of multiple connecting parts, the installation process becomes more flexible and efficient; multiple connection points allow fine-tuning during installation to ensure the optimal installation position and firmness; the connecting part is connected to the box body, and since the connecting part provides additional fixation and support, it ensures a firm connection between the fixing assembly and the box body, further improving the installation stability of the vacuum pump, and can effectively reduce the vibration transmission of the vacuum pump during operation. Combined with the use of shock-absorbing sleeves, it can further reduce noise and improve the user experience.

[0027] In some embodiments of the present application, a mounting portion is provided on the rear side of the box liner, and the mounting portion is protruded relative to the surface of the box liner;

[0028] The connecting portion is configured as a connecting bolt, the connecting bolt passes through the first fixing member and / or the second fixing member, and the connecting bolt is threadedly connected to the mounting portion.

[0029] By providing a mounting portion on the rear side of the box and fixing it with connecting bolts, the installation process of the vacuum pump is simplified, and the installer can complete the installation more quickly, thereby improving production efficiency; the protruding mounting portion provides additional support and isolation for installing the vacuum pump, reducing the vibration of the vacuum pump during operation from being transmitted to other parts of the refrigerator, thereby reducing noise and improving user experience and product quality; by using a combination of connecting bolts and the first fixing member and the second fixing member, the vacuum pump is firmly installed on the refrigerator, reducing loosening or displacement caused by vibration and extending the service life of the vacuum pump.

[0030] In some embodiments of the present application, the shock-absorbing sleeve is configured as an elastic shock-absorbing sleeve, the outer surface of the elastic shock-absorbing sleeve abuts against the fixing assembly, and the inner surface of the elastic shock-absorbing sleeve encloses the accommodating cavity.

[0031] The outer surface of the elastic shock-absorbing sleeve is designed to be in close contact with the fixed component, ensuring that the shock-absorbing sleeve is stably fixed in the refrigerator structure, providing effective support and shock-absorbing functions, and reducing displacement or loosening problems caused by vibration; the inner surface of the elastic shock-absorbing sleeve is surrounded by a accommodating cavity for accommodating the vacuum pump. This design allows the vacuum pump to be completely wrapped in the shock-absorbing sleeve to minimize vibration transmission; the elastic shock-absorbing sleeve can effectively absorb the vacuum pump through its elastic material properties, reducing vibration transmission to other parts of the refrigerator, thereby significantly reducing noise and improving the comfort of use of the refrigerator. By reducing the impact of vibration on other parts of the vacuum pump, the elastic shock-absorbing sleeve helps to extend the service life of the equipment and reduce maintenance and replacement costs.

[0032] In some embodiments of the present application, the vacuum pump assembly has a silencer cavity, which is connected to the air outlet of the vacuum pump.

[0033] By setting a silencer chamber at the vacuum pump outlet, the noise generated when the airflow is discharged can be effectively reduced, thereby improving the comfort of using the refrigerator, especially when used in a quiet environment.

[0034] In some embodiments of the present application, the outer surface of the elastic shock-absorbing sleeve and the fixing assembly form the silencer cavity;

[0035] The fixing assembly is provided with a first opening, and the elastic shock-absorbing sleeve is provided with a second opening;

[0036] The air outlet of the vacuum pump is provided with an air outlet pipe, and the air outlet pipe is connected to the muffler cavity through the first opening and the second opening in sequence.

[0037] A silencer cavity is formed between the outer surface of the elastic shock-absorbing sleeve and the fixed component. This design utilizes the existing component structure to form a silencer function in a limited space, thereby achieving the function of reducing noise while reducing the size of the equipment. At the same time, the structural characteristics of the existing components are utilized to reduce additional installation steps and complexity, making the installation process of the vacuum pump simpler and more efficient; the air outlet of the vacuum pump passes through the air outlet pipe, through the first opening and the second opening in sequence, and is connected to the silencer cavity. This design allows the airflow to be reasonably guided and buffered before entering the silencer cavity. Through reasonable opening and pipe design, the stability of the airflow path is ensured, and the impact of vibration on other components is reduced, thereby improving the stability and reliability of the entire system; by forming a silencer cavity between the elastic shock-absorbing sleeve and the fixed component, the airflow noise during operation of the vacuum pump can be effectively reduced. The silencer cavity can absorb and diffuse the airflow noise, significantly improving the comfort of use of the refrigerator.

[0038] In some embodiments of the present application, in the extension direction of the vacuum pump, the air intake of the vacuum pump and the air outlet of the vacuum pump are arranged on the same side.

[0039] Setting the air intake and outlet on the same side simplifies the internal structural layout of the vacuum pump, reduces the complexity of the pipeline, simplifies the pipeline connection and installation process, makes the installation more intuitive and convenient, and also simplifies subsequent maintenance and inspection work; by setting the air intake and outlet on the same side, the airflow path is optimized, reducing the turbulence and resistance of the airflow in the pump, helping to improve the efficiency and performance of the vacuum pump, reducing vibration and noise, and thereby improving the comfort of use of the refrigerator. The simplification and optimization of the airflow path helps to improve the working efficiency of the vacuum pump, reduce energy consumption, and thus improve the overall performance of the refrigerator.

[0040] The refrigerator in the embodiment of the present application simplifies the installation process of the vacuum pump and improves the installation efficiency by installing the vacuum pump in a shock-absorbing sleeve and connecting it with a fixing component; the design of the shock-absorbing sleeve effectively reduces the vibration generated by the vacuum pump during operation, thereby reducing noise and improving the user experience; the vacuum pump is connected to the accommodating space of the low-pressure fresh-keeping drawer through an air suction pipe, which can effectively extract air and form a negative pressure environment, which helps to extend the shelf life of food and maintain the freshness of food.

[0066] As described in the background art, in the related art, a vacuum drawer is installed inside a refrigerator body and inside a refrigerator liner. Specifically, a drawer frame is provided inside the refrigerator liner, and the drawer frame is provided inside the refrigerator compartment. A drawer cavity with a front opening is provided inside the drawer frame. The vacuum drawer can be placed into the drawer cavity through the front opening of the drawer cavity, thereby sealing the drawer cavity and forming a closed space inside the drawer cavity. A vacuum pump or other vacuuming device is then used to evacuate the drawer, thereby maintaining a certain vacuum environment inside the vacuum drawer. The vacuum pump of the vacuum drawer usually needs to be installed on the air duct assembly of the refrigerator body, and the vacuum pump needs to be fixed to the air duct assembly through a structure such as a sheath, which makes the installation process of the vacuum pump cumbersome.

[0067] In view of this, the refrigerator of the embodiment of the present application simplifies the installation process of the vacuum pump and improves the installation efficiency by installing the vacuum pump in the shock-absorbing sleeve and connecting it with a fixing component.

[0068] The vacuum pump is mounted on the rear side of the liner. When the vacuum pump draws air from the liner through the suction pipe located in the mounting portion, negative pressure is created inside the liner, causing local deformation of the liner. This mounting portion improves the strength of the liner at the corresponding location, reducing the likelihood of deformation of the liner at the suction pipe, thereby reducing the possibility of the vacuum pump being squeezed by the deformation of the liner.

[0069] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0075] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0076] refer to Figures 1-4 An embodiment of the present application provides a refrigerator, including a body 01, which may be formed with a refrigeration compartment.

[0077] The box 01 may further include a refrigeration system, which is connected to the refrigeration compartment and supplies cold air to the refrigeration compartment.

[0078] Box 02 is installed in the refrigeration room.

[0079] Low-pressure fresh-keeping drawer 03 is movably disposed within container 02. When located within container 02, low-pressure fresh-keeping drawer 03 and container 02 together form a storage space. The air pressure in the low-pressure fresh-keeping drawer can be maintained between 0.75 atm and 0.92 atm, improving the drawer's ability to preserve food.

[0080] The vacuum pump assembly 100 includes a fixing assembly 110 , which can be disposed on the box 02 .

[0081] The vacuum pump assembly 100 further includes a shock-absorbing sleeve 120 , which can be connected to the box 02 via the fixing assembly 110 , and the shock-absorbing sleeve 120 is provided with an accommodating cavity.

[0082] The vacuum pump assembly 100 further includes a vacuum pump 130 disposed in the accommodating cavity.

[0083] The air intake of the vacuum pump 130 may be provided with an air intake pipe, which passes through the box 02 and is used to communicate with the accommodating space.

[0084] By installing the vacuum pump 130 in the shock-absorbing sleeve 120 and connecting it using the fixing component 110, the installation process of the vacuum pump is simplified and the installation efficiency is improved; the design of the shock-absorbing sleeve 120 effectively reduces the vibration generated by the vacuum pump 130 during operation, thereby reducing noise and improving the user experience; the vacuum pump 130 is connected to the accommodating space of the low-pressure fresh-keeping drawer 03 through the suction pipe, which can effectively extract air and form a negative pressure environment, which helps to extend the shelf life of the food and maintain the freshness of the food.

[0085] In some possible implementations, the fixing assembly 110 may be located at the rear side of the box 02 , and the fixing assembly 110 may be detachably connected to the box 02 .

[0086] The vacuum pump assembly 100 is directly installed on the box 02, so that the communication distance between the vacuum pump 130 and the accommodating space is shortened. Compared with installing the vacuum pump 130 on the air duct assembly of the refrigerator's refrigeration system, shorter pipes can be used to reduce costs. At the same time, the shorter pipes as a whole avoid relative movement when installed on the box 02, thereby avoiding the risk of pipe extrusion.

[0087] The vacuum pump 130 is installed on the rear side of the box 02, which facilitates the installation and maintenance of the vacuum pump 130. Users or maintenance personnel can easily access and operate the vacuum pump components, reducing the time and complexity of installation and maintenance; the fixing component 110 is placed on the rear side of the box 02, which helps to better utilize the internal space of the refrigerator and avoid occupying too much front or side space, thereby not affecting the layout of other functional components.

[0088] For example, a mounting portion 200 may be provided on the rear side of the box 02 . The mounting portion 200 is provided to protrude relative to the box 02 , and the mounting portion 200 is located on one side of the center line of the box 02 .

[0089] It should be noted that the centerline of the box 02 can be used to indicate the horizontal centerline of the box 02. The mounting portion 200 is located to one side of the centerline of the box 02, which can be used to indicate that the mounting portion 200 is not located in the middle of the box 02. The mounting portion 200 can be close to the left edge of the box 02, or the mounting portion 200 can be close to the right edge of the box 02.

[0090] In a plane perpendicular to the depth of the box 02, the centerline of the box 02 can divide the box 02 into a left half and a right half. The mounting portion 200 can be completely disposed in the left half or the right half of the box 02, or a portion of the mounting portion 200 can also coincide with the centerline of the box 02.

[0091] It is easy to understand that since the edge structure of the box 02 is more solid, when the vacuum pump 130 draws air from the box 02 through the suction pipe located at the mounting portion 200, the edge of the box 02 is not easily deformed. The mounting portion 200 is located on one side of the center line of the box 02, which can reduce the possibility of deformation of the mounting portion 200, making the structure of the vacuum pump 130 located at the mounting portion 200 more stable.

[0092] The vacuum pump is mounted on the rear side of the liner. When the vacuum pump draws air from the liner through the suction pipe located in the mounting portion, negative pressure is created inside the liner, causing local deformation of the liner. This mounting portion improves the strength of the liner at the corresponding location, reducing the likelihood of deformation of the liner at the suction pipe, thereby reducing the possibility of the vacuum pump being squeezed by the deformation of the liner.

[0093] The fixing assembly 110 and the box 02 are connected in a detachable manner, which allows the vacuum pump assembly 100 to be easily disassembled and reinstalled when needed, simplifying the maintenance and replacement process; through the fixed position and detachable design of the above-mentioned vacuum pump assembly 100, the shock-absorbing sleeve 120 and the fixing assembly 110 can effectively isolate and reduce vibration transmission, further reducing the noise during the operation of the vacuum pump.

[0094] refer to Figure 5-Figure 6 In some possible implementations, the fixing assembly 110 includes a first fixing member 111 and a second fixing member 112 .

[0095] A shock-absorbing sleeve 120 may be accommodated between the first fixing member 111 and the second fixing member 112 .

[0096] At least one of the first fixing member 111 and the second fixing member 112 is connected to the box 02 .

[0097] By accommodating the shock-absorbing sleeve 120 between the first fixing member 111 and the second fixing member 112, the installation process of the vacuum pump 130 is simplified; the design of the fixing member makes the installation process more intuitive and efficient; the use of the shock-absorbing sleeve 120 effectively absorbs and isolates the vibration generated by the vacuum pump 130 during operation, thereby reducing noise and improving the user experience of the refrigerator, especially when a quiet environment is required; at least one of the first fixing member 111 and the second fixing member 112 is connected to the box 02, ensuring the stability of the fixing assembly 110, while providing flexibility for easy installation and maintenance; the structural design of the first fixing member 111 and the second fixing member 112 provides additional support and stability, ensuring that the vacuum pump remains stable during operation and is not easy to shift.

[0098] In some possible implementations, the first fixing member 111 may face the box 02 .

[0099] The second fixing member 112 may be away from the box 02 .

[0100] The fixing assembly 110 also includes a connecting portion 113 and a snap-fit ​​fixing portion 114 . The first fixing member 111 and the second fixing member 112 can be connected via the snap-fit ​​fixing portion 114 . The first fixing member 111 and the second fixing member 112 can be connected to the box 02 via the connecting portion 113 .

[0101] The first fixing member 111 is designed to face the box 02, so that the first fixing member 111 can directly contact or be close to the box 02, thereby providing stable support; the second fixing member 112 is designed to be away from the box 02, so that the second fixing member 112 can provide support and fixing at a farther position, while providing sufficient space for the shock-absorbing sleeve 120; the buckling fixing part 114 and the connecting part 113 connect the two fixing members together and connect to the box 02 to form an integral fixed structure.

[0102] The first fixing member 111 and the second fixing member 112 are connected together by snapping the fixing portion 114 to form an integral fixing assembly, which simplifies the installation process and makes the installation more intuitive and efficient; the design of the connecting portion 113 helps to stabilize the entire fixing assembly, thereby reducing the vibration transmission of the vacuum pump 130 during operation, and combined with the use of the shock-absorbing sleeve 120, it can effectively reduce noise; the fixing member is connected to the box 02 through the connecting portion 113, providing additional support and stability, ensuring that the vacuum pump remains stable during operation and is not easy to shift.

[0103] refer to Figure 8In some possible embodiments, the fastening and fixing portion 114 includes a buckle 1141 and a clamping block 1142. The buckle 1141 is connected to the first fixing member 111, and the clamping block 1142 is connected to the second fixing member 112. The buckle 1141 and the clamping block 1142 fix the first fixing member 111 and the second fixing member 112 together by clamping. It should be noted that the buckle 1141 can also be connected to the second fixing member 112, and the clamping block 1142 to the first fixing member 111. As long as the buckle 1141 and the clamping block 1142 can achieve a connection effect on the first fixing member 111 and the second fixing member 112, the embodiment of the present application does not impose too many restrictions on the installation order of the buckle 1141 and the clamping block 1142. Exemplarily, the buckle 1141 is connected to the first fixing member 111, and the snap-fit ​​block 1142 is connected to the second fixing member 112, which is more in line with the operation sequence and facilitates the first fixing member 111 to be fastened and fixed to the second fixing member 112 from above.

[0104] In some possible implementations, there may be multiple buckling and fixing portions 114 symmetrically disposed on both sides of the first fixing member 111 and the second fixing member 112 .

[0105] In some possible embodiments, the buckle 1141 is integrally formed with the first fixing member 111, and the snap-fit ​​block 1142 is integrally formed with the second fixing member 112, so that the fixation between the first fixing member 111 and the second fixing member 112 is more secure, avoiding loose fastening due to loosening of the buckle 1141 or the snap-fit ​​block 1142.

[0106] It should be understood that as long as the snap-fit ​​fixing portion 114 can connect and fix the first fixing member 111 and the second fixing member 112 , the embodiment of the present application does not impose too many restrictions on the specific structure of the snap-fit ​​fixing portion 114 .

[0107] refer to Figure 7 In some possible implementations, there may be multiple connecting portions 113 .

[0108] The connecting portion 113 may pass through the first fixing member 111 and / or the second fixing member 112 , and the connecting portion 113 may be connected to the box 02 .

[0109] The connecting portion 113 passes through the first fixing member 111 and / or the second fixing member 11, so that the connecting portion 113 not only connects the first fixing member 111 and the second fixing member 112 together, but also provides additional support and fixing; multiple connecting portions 113 can provide support and fixation at multiple points, thereby enhancing the overall stability of the fixing assembly 110, effectively resisting vibration and displacement, and ensuring the stability of the vacuum pump 130 during operation; through the design of multiple connecting portions 113, the installation process becomes more flexible and efficient; multiple connection points allow fine-tuning during installation to ensure the optimal installation position and firmness; the connecting portion 113 is connected to the box 02. Since the connecting portion 113 provides additional fixation and support, it ensures a firm connection between the fixing assembly 110 and the box 02, further improving the installation stability of the vacuum pump 130, and can effectively reduce the vibration transmission of the vacuum pump 130 during operation. Combined with the use of the shock-absorbing sleeve 120, it can further reduce noise and improve the user experience.

[0110] In some possible implementations, the connection portion 113 may be configured as a connection bolt, which may pass through the first fixing member 111 and / or the second fixing member 112 , and the connection bolt may be threadedly connected to the mounting portion 200 .

[0111] By providing a mounting portion 200 on the rear side of the box 02 and fixing it with connecting bolts, the installation process of the vacuum pump 130 is simplified, and the installer can complete the installation more quickly, thereby improving production efficiency; the protruding mounting portion 200 provides additional support and isolation for installing the vacuum pump 130, reducing the vibration of the vacuum pump 130 during operation from being transmitted to other components of the refrigerator, thereby reducing noise and improving user experience and product quality; by using a combination of connecting bolts and the first fixing member 111 and the second fixing member 112, the vacuum pump 130 is firmly mounted on the refrigerator, and the firm connection reduces loosening or displacement caused by vibration, thereby extending the service life of the vacuum pump 130.

[0112] In some possible embodiments, the connecting portion 113 of the connecting bolt has a gasket between the first fixing member 111 and / or the second fixing member 112, which can fill the gap between the first fixing member 111 and / or the second fixing member 112 and the mounting portion 200, so that the fixing component is more firmly installed on the mounting portion 200, and the connecting portion 113 is not easy to loosen, further enhancing the stability of the fixing component on the mounting portion 200.

[0113] In some possible implementations, the shock-absorbing sleeve 120 is configured as an elastic shock-absorbing sleeve 120 , the outer surface of the elastic shock-absorbing sleeve 120 may abut against the fixing assembly 110 , and the inner surface of the elastic shock-absorbing sleeve 120 may enclose an accommodating cavity.

[0114] The outer surface of the elastic shock-absorbing sleeve 120 is designed to be in close contact with the fixing component 110, ensuring that the shock-absorbing sleeve 120 is stably fixed in the refrigerator structure, providing effective support and shock-absorbing functions, and reducing displacement or loosening problems caused by vibration; the inner surface of the elastic shock-absorbing sleeve 120 forms a accommodating cavity for accommodating the vacuum pump. This design allows the vacuum pump 130 to be completely wrapped in the shock-absorbing sleeve 120 to minimize vibration transmission; the elastic shock-absorbing sleeve 120 can effectively absorb the vacuum pump 130 through its elastic material properties, reduce the vibration transmission to other parts of the refrigerator, thereby significantly reducing noise and improving the comfort of use of the refrigerator. It can also reduce the impact of vibration on other parts of the vacuum pump 130. The elastic shock-absorbing sleeve 120 helps to extend the service life of the equipment and reduce maintenance and replacement costs.

[0115] It should be noted that the shock-absorbing sleeve 120 can be made of natural rubber or synthetic rubber. The rubber material has excellent elasticity and can effectively absorb and cushion vibrations; it has good wear resistance and is suitable for long-term use; it has good weather resistance and can maintain stable performance in different environments.

[0116] The shock-absorbing sleeve 120 can also use polyurethane (PU). Polyurethane material is very wear-resistant and suitable for use in high-wear environments; polyurethane has excellent elasticity and can effectively absorb shock; silicone material can maintain elasticity and performance under extreme temperatures.

[0117] The shock-absorbing sleeve 120 may also be made of ethylene vinyl acetate (EVA) foam. Ethylene vinyl acetate foam is lightweight and easy to process and install. Ethylene vinyl acetate foam can effectively absorb shock and vibration.

[0118] It should be noted that, in the embodiment of the present application, as long as the elastic shock-absorbing sleeve 120 can play a role in reducing the shock of the vacuum pump 130, the embodiment of the present application does not impose too many restrictions on the specific material of the shock-absorbing sleeve 120.

[0119] refer to Figure 9-10 In some possible implementations, the vacuum pump assembly 100 may have a muffler chamber 140 , and the muffler chamber 140 may be in communication with an air outlet of the vacuum pump 130 .

[0120] The silencing chamber 140 is designed to communicate with the outlet of the vacuum pump 130. This means that when the vacuum pump 130 exhausts gas, the gas first enters the silencing chamber 140. The silencing chamber, through its specific structure and material properties, can effectively reduce airflow noise. The airflow is diffused and absorbed in the silencing chamber, reducing the noise generated by direct exhaust.

[0121] During use, when the vacuum pump 130 is in operation, the generated airflow enters the silencer chamber 140 through the air outlet. The silencer chamber 140 reduces the intensity of the airflow noise by changing the airflow path and absorbing sound waves.

[0122] By providing a silencer chamber 140 at the air outlet of the vacuum pump 130, the noise generated when the air is discharged can be effectively reduced, thereby improving the comfort of using the refrigerator, especially when used in a quiet environment.

[0123] In some possible implementations, a silencer cavity 140 may be formed between the outer surface of the elastic shock-absorbing sleeve 120 and the fixing assembly 110 .

[0124] The fixing assembly 110 may be provided with a first opening 115 , and the elastic shock-absorbing sleeve 120 may be provided with a second opening 121 .

[0125] The air outlet of the vacuum pump 130 may be provided with an air outlet pipe 131 , and the air outlet pipe 131 may be connected to the muffler chamber 140 through the first opening 115 and the second opening 121 in sequence.

[0126] A silencer chamber 140 is formed between the outer surface of the elastic shock-absorbing sleeve 120 and the fixed component 110. This design utilizes the existing component structure to form a silencer function in a limited space, thereby achieving the function of reducing noise while reducing the size of the equipment. At the same time, the structural characteristics of the existing components are utilized to reduce additional installation steps and complexity, making the installation process of the vacuum pump 130 simpler and more efficient; the air outlet of the vacuum pump 130 passes through the first opening 115 and the second opening 121 in sequence through the air outlet pipe 131, and is connected to the silencer chamber 140. This design allows the airflow to be reasonably guided and buffered before entering the silencer chamber 140. Through reasonable opening and pipe design, the stability of the airflow path is ensured, and the impact of vibration on other components is reduced, thereby improving the stability and reliability of the entire system; by forming the silencer chamber 140 between the elastic shock-absorbing sleeve 120 and the fixed component 110, the airflow noise during operation of the vacuum pump can be effectively reduced. The silencer chamber 140 can absorb and diffuse the airflow noise, significantly improving the comfort of use of the refrigerator.

[0127] In some possible implementations, in the extension direction of the vacuum pump 130 , the air intake of the vacuum pump 130 and the air outlet of the vacuum pump 130 may be arranged on the same side.

[0128] Setting the air intake and air outlet on the same side simplifies the internal structural layout of the vacuum pump 130, reduces the complexity of the pipeline, simplifies the pipeline connection and installation process, makes the installation more intuitive and convenient, and also simplifies subsequent maintenance and inspection work; by setting the air intake and air outlet on the same side, the airflow path is optimized, reducing the turbulence and resistance of the airflow in the pump, which helps to improve the efficiency and performance of the vacuum pump 130, reduce vibration and noise, and improve the comfort of use of the refrigerator. The simplification and optimization of the airflow path helps to improve the working efficiency of the vacuum pump, reduce energy consumption, and thus improve the overall performance of the refrigerator.

[0129] In some possible implementations, during specific installation:

[0130] The box 02 is installed in the refrigeration room, and the low-pressure fresh-keeping drawer 03 is movably arranged in the box 02. When the low-pressure fresh-keeping drawer 03 is located in the box 02, they together form an accommodating space for storing food that needs to be kept fresh.

[0131] The fixing assembly 110 is installed on the rear side of the box 02 and is detachably connected to the box. The elastic shock-absorbing sleeve 120 is connected to the box 02 through the fixing assembly 110. The outer surface of the shock-absorbing sleeve 120 abuts against the fixing assembly 110, and the inner surface forms a receiving cavity for accommodating the vacuum pump 130.

[0132] The vacuum pump 130 is arranged in the accommodating cavity of the shock-absorbing sleeve 120. The suction port of the vacuum pump passes through the box 02 through the suction pipe and is connected to the accommodating space to extract the air in the low-pressure fresh-keeping drawer to form a negative pressure state.

[0133] A silencer chamber 140 in the vacuum pump assembly 100 communicates with the air outlet of the vacuum pump 130 to reduce noise. This chamber is enclosed by the outer surface of the elastic damping sleeve 120 and the fixed assembly 110. The fixed assembly 110 has a first opening 115, and the elastic damping sleeve 120 has a second opening 121. The vacuum pump's air outlet pipe 131 communicates with the silencer chamber 140 through these openings.

[0134] The first fixing member 111 and the second fixing member 112 are connected by using a plurality of connecting parts 113 , and are connected to the box 02 via these connecting parts 113 .

[0135] A mounting portion 200 is provided on the rear side of the box 02 , and the connecting portion 113 passes through the first fixing member 111 and the second fixing member 112 and is threadedly connected to the mounting portion 200 to ensure a secure installation of the fixing assembly.
