Magnetic shielding materials include silicon steel, which has high magnetic permeability and can effectively guide and shield magnetic fields. By shielding unwanted magnetic field directions, the first magnetic shielding component can prevent magnetic fields from interfering with other components of the refrigerator or the external environment, improving the overall performance and safety of the refrigerator.

[0046] The combination of magnetic elements and a first magnetic shield allows for directional control of the magnetic field, ensuring that the magnetic field acts only on the desired area.

[0077] Refrigerators are equipped with magnetic field devices. These devices generate magnetic fields that interfere with the metabolic activities of bacteria and mold in the vacuum drawers, thus slowing down food spoilage. However, these magnetic field devices require a stable power supply to continuously generate an effective magnetic field.

[0078] In related technologies, some refrigerators supply power to magnetic field devices wirelessly. Wireless power supply requires integrating a wireless power transmission system inside the refrigerator, which must be compatible with the refrigerator's refrigeration system. This necessitates designing the refrigerator's internal structure to ensure that wireless power transmission does not interfere with the cooling effect. While wireless power supply reduces physical connections, it requires complex system integration and structural adjustments.

[0079] Some refrigerators use a wired power supply to power the magnetic field device, connecting the cable from the power source to the device. This can lead to complex and messy wiring in the compact space of a refrigerator. If the magnetic field device is located inside the vacuum preservation compartment, the cable needs to pass through multiple layers, increasing the difficulty of installation and maintenance.

[0080] Therefore, existing refrigerators have the problem of having a complex power supply structure to power the magnetic field device.

[0081] In view of this, this application provides a refrigerator, which includes an inner liner, a mounting member, a vacuum drawer, a magnetic field device, and an electrical connector. The inner liner is configured to form a storage compartment with a front opening; the mounting member is located in the storage compartment and is configured to form a mounting cavity with a front opening; the vacuum drawer is located in the mounting cavity and includes a drawer body and a lid. The drawer body is configured to form a receiving cavity with a top opening; the lid closes to the opening of the drawer body; the lid and the drawer body are movably connected; the magnetic field device is disposed on the outer periphery of the vacuum drawer and is used to generate a magnetic field; the electrical connector includes a power supply part and an electrical connection part. The power supply part is located in the storage compartment; the power supply part is disposed on the side of the mounting member opposite to the opening of the inner liner; the power supply part is used to be electrically connected to an external power source; a portion of the electrical connection part is located in the mounting cavity; the electrical connection part is disposed on the side of the vacuum drawer opposite to the opening of the inner liner; the electrical connection part is electrically connected to the magnetic field device. Along the pulling direction of the vacuum drawer, the power supply part and the electrical connection part are used for docking.

[0082] In this embodiment, a power supply unit is provided on the outside of the mounting component, which receives external power. An electrical connection unit is provided on the side of the vacuum drawer opposite to the opening of the inner liner. The electrical connection unit is electrically connected to the magnetic field device. By pulling the drawer out, the power supply unit and the electrical connection unit align, thereby enabling the external power source to supply power to the magnetic field device. This method of power supply through alignment automatically connects or disconnects when the drawer is pushed in or pulled out, simplifying the power supply structure. Furthermore, it eliminates the need for manual plugging and unplugging of cables, greatly simplifying user operation and improving ease of use. Simultaneously, the absence of frequent manual plugging and unplugging reduces the risk of wear and damage to the electrical connections, extending the component's lifespan.

[0083] The docking method eliminates the complexity of traditional cable connections, reduces cable clutter inside the refrigerator, and contributes to a cleaner interior design. Since no additional cable management space is required, the docking method helps optimize the use of internal space.

[0084] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0085] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0086] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0087] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0088] Reference Figures 1 to 6 As shown, this application embodiment provides a refrigerator 100, including:

[0089] The inner liner 200 is constructed to form a storage compartment with a front opening;

[0090] Mounting component 210, located in the storage compartment, is configured to form a mounting cavity with a front opening;

[0091] Vacuum drawer 300, located within the mounting cavity, includes:

[0092] The drawer body 310 is constructed to form a receiving cavity with a top opening;

[0093] The lid 320 covers the opening of the drawer body 310; the lid 320 and the drawer body 310 are movably connected.

[0094] The magnetic field device, located inside the mounting cavity, is used to generate a magnetic field.

[0095] Electrical connector 900, comprising:

[0096] Power supply unit 910 is located in the storage room; power supply unit 910 is provided on the side of the mounting piece 210 opposite to the opening of the inner liner 200; power supply unit 910 is used for electrical connection with an external power source.

[0097] Electrical connection part 920, part of which is located in the mounting cavity; electrical connection part 920 is provided on the side of the vacuum drawer 300 opposite to the opening of the inner liner 200; electrical connection part 920 is electrically connected to the magnetic field device.

[0098] Along the direction of the vacuum drawer 300's pull-out, the power supply unit 910 and the electrical connection unit 920 are connected. The direction of the vacuum drawer 300's pull-out is referenced... Figure 1 The direction indicated by X in the middle.

[0099] For example, refrigerator 100 may include a cabinet. The cabinet may include an outer shell, an inner liner 200 located within the outer shell, and a foam layer filling the space between the outer shell and the inner liner 200. The inner liner 200 may be configured with a storage compartment for holding food and other items. The storage compartment may have an access opening through which items can be accessed and placed.

[0100] The storage compartment may be equipped with an installation component 210. The installation component 210 is constructed to form an installation cavity, and the installation component 210 can be a barrel body to form a vacuum preservation compartment.

[0101] A vacuum drawer 300 is installed in the vacuum preservation chamber. The vacuum drawer 300 is used to hold items to be refrigerated, which may include multiple categories of items. For example, these categories may include Class I, Class II, Class III, and Class IV items. Class I items may be fruits, Class II items may be vegetables, Class III items may be fresh meat, and Class IV items may be fungi. It is understood that the items to be refrigerated may also be other types of items, which will not be elaborated upon in this embodiment.

[0102] The vacuum drawer 300 forms an independent, sealed space, or containment cavity, inside the refrigerator 100. The vacuum device removes air from the vacuum drawer 300, reducing internal air pressure and thus decreasing the oxygen content, slowing down food oxidation and bacterial growth, and achieving a longer preservation effect.

[0103] The vacuum environment of the Vacuum Drawer 300 inhibits food oxidation and reduces moisture loss, keeping fruits, vegetables, meats, and other ingredients fresh for longer. Vacuum preservation better retains the vitamins, minerals, and other nutrients in food, avoiding nutrient loss caused by oxidation.

[0104] For example, the vacuum drawer 300 includes a drawer body 310 and a lid 320. The drawer body 310 slides relative to the inner liner 200 to be pulled out or pushed into the storage compartment. The lid 320 closes onto the opening of the drawer body 310. The lid 320 is used to ensure that the vacuum environment inside the drawer body 310 is not disrupted, while also providing a sealing function to enhance the vacuum effect.

[0105] A vacuum device is connected to the drawer body 310 and is used to adjust the vacuum level of the storage cavity. The vacuum device can adjust the vacuum level of the storage cavity according to the storage requirements of different items, achieving a personalized storage environment. The vacuum device includes a vacuum pump and tubing; the vacuum pump extracts air from the storage cavity through the tubing, reducing the oxygen content.

[0106] A magnetic field device is located on the outer periphery of the vacuum drawer 300. The device is configured to generate a magnetic field that acts on the item to be refrigerated. This magnetic field affects gene expression, alters cell membrane permeability, and reduces the metabolic rate of the item. It also forms more hydrogen bonds, reducing weight loss and fluid loss, and slowing down tissue softening. Furthermore, the magnetic field eliminates hydrogen peroxide and superoxide radicals from the item, protecting its cells from oxidative damage and thus preserving its freshness. In addition, the magnetic field's strong penetrability effectively penetrates various packaging materials, ensuring good preservation even when the item is wrapped in packaging before being stored in the refrigerator 100.

[0107] Since the magnetic field device requires external power, in this embodiment, a power supply unit 910 is provided on the outside of the mounting component 210. The power supply unit 910 obtains external power. An electrical connection unit 920 is provided on the side of the vacuum drawer 300 opposite to the opening of the inner liner 200. The electrical connection unit 920 is electrically connected to the magnetic field device. By pulling the drawer out, the power supply unit 910 and the electrical connection unit 920 are connected to each other, thereby enabling the external power source to supply power to the magnetic field device. This method of power supply through connection automatically connects or disconnects when the drawer body 310 is pushed in or pulled out, simplifying the power supply structure. At the same time, it eliminates the need for users to manually plug and unplug cables, greatly simplifying user operation and improving ease of use. Furthermore, since there is no frequent manual plugging and unplugging, the risk of wear and damage to the electrical connection unit 900 is reduced, extending the service life of the components.

[0108] The docking method eliminates the complexity of traditional cable connections, reduces cable clutter inside equipment, and contributes to a cleaner internal design. Since no additional cable management space is required, the docking method helps optimize the use of internal space.

[0109] Drilling designs typically include guiding and positioning features to ensure accurate connections every time. This improves the reliability of electrical connections and reduces the likelihood of poor contact.

[0110] The electrical connection part 920 can be a plug. The power supply part 910 can be a power supply docking terminal.

[0111] As one feasible implementation method, refer to Figures 4 to 6 As shown, along the pull-out direction of the vacuum drawer 300, a first mating end is formed on the side of the power supply unit 910 near the electrical connection unit 920, and a second mating end is formed on the side of the electrical connection unit 920 near the power supply unit 910; the portion of the second mating end is located in the mounting cavity.

[0112] Mounting member 210 has a mounting hole on the side opposite to the opening of inner liner 200.

[0113] The second docking end has a through-hole for connecting with the first docking end.

[0114] For example, a first mating end is formed on the side of the power supply section 910 near the electrical connection section 920. The first mating end is used to mate with the second mating end to achieve power transmission.

[0115] The second mating end is formed on the side of the electrical connection portion 920 near the power supply portion 910 and is located within the mounting cavity. A mounting hole allows a portion of the second mating end to pass through for mating with the first mating end. The mating of the second mating end with the first mating end via the mounting hole ensures the stability of the electrical connection.

[0116] As the vacuum drawer 300 moves in the pulling direction, the first and second mating ends can automatically engage or disengage, simplifying user operation. This ensures seamless electrical connection with each drawer movement, providing a continuous power supply. Guided by mounting holes, the second mating end precisely engages with the first, reducing the risk of poor contact. Automatic engagement reduces manual operation and lowers the risk of wear and damage to the mating ends.

[0117] In one feasible implementation, the first mating end abuts against the outer wall of the mounting member 210; the first mating end is formed with a first recess 930, and the recess opening of the first recess 930 faces the second mating end.

[0118] The second mating end abuts against the inner wall of the mounting part 210; the second mating end has a second recess 940, and the recess opening of the second recess 940 faces the first mating end.

[0119] The second mating end also has a protrusion 950; part of the protrusion 950 is located in the second recess 940; the protrusion 950 passes through the mounting hole and is embedded in the first recess 930.

[0120] For example, the first mating end abuts against the outer wall of the mounting member 210, providing a stable support point. The first mating end has a first recess 930 with its opening facing the second mating end. This recess is designed to accommodate a protrusion 950 from the second mating end, ensuring a secure connection.

[0121] The second mating end abuts against the inner wall of the mounting member 210, further stabilizing the connection structure. The second mating end has a second recess 940, the opening of which faces the first mating end. Additionally, the second mating end also has a protrusion 950.

[0122] The protrusion 950 passes through the mounting hole and is fitted into the first recess 930. This design ensures a mechanical lock between the two mating ends, preventing the connector from loosening or falling off during use.

[0123] The first recess 930 and the protrusion 950 work together to achieve a secure mechanical connection between the first and second mating ends, reducing the risk of loosening and poor contact. The structure of the first recess 930 and the protrusion 950 facilitates automatic alignment of the two mating ends, simplifying the installation process and improving connection reliability. Because the mating structure provides precise positioning and a stable connection, wear on the electrical connector 900 is reduced during use.

[0124] As one possible implementation, the refrigerator 100 also includes a first seal disposed between the first mating end and the mounting member 210.

[0125] For example, the function of the first seal is to provide additional sealing protection against dust, moisture, and other external contaminants entering the connection area. This helps maintain the reliability and durability of the electrical connection. The first seal can be a rubber sealing ring.

[0126] The refrigerator 100 also includes a second seal, which is disposed between the second mating end and the mounting member 210.

[0127] For example, the second seal provides additional sealing protection against dust, moisture, and other external contaminants from entering the connection area. This helps maintain the reliability and durability of the electrical connection. The second seal can be a rubber sealing ring. The second seal is adhesively bonded to the mounting bracket and the vacuum drawer.

[0128] In some embodiments, the refrigerator 100 includes a first seal and a second seal. The first and second seals work together to provide double sealing protection, further preventing dust, moisture, and other external contaminants from entering the connection area. The double-seal design improves the airtightness of the connection area and reduces the penetration of air and moisture.

[0129] As one possible implementation, the magnetic field device includes at least two first magnetic field devices 610 and at least two second magnetic field devices; the at least two second magnetic field devices are arranged in a one-to-one correspondence with the at least two first magnetic field devices 610.

[0130] The cover 320 has at least two first mounting slots on the side opposite to the drawer body 310; each first mounting slot is equipped with a first magnetic field device 610.

[0131] The drawer body 310 has at least two second mounting slots on the side opposite to the cover 320; each second mounting slot is equipped with a second magnetic field device.

[0132] For example, a first mounting groove is provided on the side of the cover 320 opposite to the drawer body 310 to accommodate the first magnetic field device 610. By providing the first mounting groove, the first mounting groove provides protection for the first magnetic field device 610, preventing damage to the first magnetic field device 610 during use. At the same time, placing the first magnetic field device 610 in the first mounting groove makes the interior design of the refrigerator 100 more aesthetically pleasing and concise.

[0133] A second mounting groove is provided on the side of the drawer body 310 opposite to the cover 320 to accommodate the second magnetic field device. The second mounting groove provides protection for the second magnetic field device, preventing damage during use. At the same time, placing the second magnetic field device in the second mounting groove makes the interior design of the refrigerator 100 more aesthetically pleasing and concise.

[0134] As one possible implementation, the refrigerator 100 also includes a divider located in the receiving cavity.

[0135] The separator is configured to divide the receiving cavity into at least two sub-receiving cavities;

[0136] The number of magnetic field devices is at least two, and at least two magnetic field devices are arranged in a one-to-one correspondence with at least two sub-accommodating cavities.

[0137] In some embodiments, a groove is provided on the bottom wall of the drawer body 310, and a connecting protrusion is provided on one side of the divider. The connecting protrusion can be embedded in the groove to achieve a detachable connection between the divider and the drawer body 310. It is understood that there can be multiple grooves, and users can freely adjust the position of the divider as needed, thereby changing the size and number of sub-cavities. This flexibility allows users to personalize the configuration according to the size of different items and storage needs. This design supports modular configuration, allowing users to easily reconfigure the internal layout of the drawer to suit different storage requirements.

[0138] By dividing the containment chamber into multiple sub-containment chambers, each sub-containment chamber can independently adjust its vacuum level and magnetic field strength. This independence allows users to provide the most suitable preservation environment for different types of food or items.

[0139] In other embodiments, the divider is connected to the inner wall of the drawer body 310 by fasteners such as screws. Screw connections provide greater stability, ensuring the divider will not easily move or fall off during use. The divider divides the accommodating cavity into multiple sub-accommodating cavities, each of which can be independently adjusted for vacuum and magnetic field strength. This independence allows users to provide the most suitable storage environment for different types of food or items.

[0140] For example, the divider is a partition that divides the drawer body 310 into multiple sub-cavities, i.e., multiple storage areas. The multiple storage areas may include a first storage area, a second storage area, a third storage area, and a fourth storage area. The first storage area can be used to accommodate first-class items, the second storage area can be used to accommodate second-class items, the third storage area can be used to accommodate third-class items, and the fourth storage area can be used to accommodate fourth-class items.

[0141] Along the height of the refrigerator 100, at least two first magnetic field devices 610 and at least two second magnetic field devices are arranged in a one-to-one correspondence. This correspondence allows for independent and precise control of the magnetic field in each sub-cavity, ensuring that the magnetic field strength and distribution in each sub-cavity meet specific storage requirements. Users can flexibly adjust the strength of each pair of magnetic field devices according to different storage needs, thereby achieving a personalized storage environment.

[0142] As one feasible implementation method, refer to Figure 7 and Figure 8 As shown, a third mounting groove 370 is also provided on the side of the cover 320 away from the drawer body 310; the third mounting groove 370 is connected to the first mounting groove.

[0143] The third mounting slot 370 is provided with a first connector, which is used to electrically connect the first magnetic field device 610 and the electrical connection part 920.

[0144] The drawer body 310 is provided with a fourth mounting groove on the side opposite to the cover 320; the fourth mounting groove is connected to the second mounting groove.

[0145] The fourth mounting slot is provided with a second connector, which is used to electrically connect the second magnetic field device and the electrical connection part 920.

[0146] For example, the first connector is disposed within the third mounting slot 370. The third mounting slot 370 provides a protective channel for the first connector. The first connector is used to electrically connect the first magnetic field device 610 and the electrical connection portion 920, ensuring that the first magnetic field device 610 on the cover 320 can receive a power supply. The first connector can be a wire.

[0147] By providing a third mounting slot 370 in the cover 320, the first connector achieves a clear wiring path, reducing cable exposure and clutter. The third mounting slot 370 provides physical protection, reducing the risk of damage to the first connector and improving system durability. The clear wiring and connection path simplifies system inspection and maintenance, reducing maintenance costs. With a stable power supply, the first magnetic field device 610 can perform its functions more effectively.

[0148] The second connector is disposed within the fourth mounting slot. The fourth mounting slot provides a protective channel for the second connector. The second connector is used to electrically connect the second magnetic field device and the electrical connection part 920, ensuring that the second magnetic field device on the cover 320 can receive a power supply. The second connector can be a wire.

[0149] By providing a fourth mounting slot in the cover 320, the second connector achieves a well-organized wiring path, reducing cable exposure and clutter. The fourth mounting slot provides physical protection, reducing the risk of damage to the second connector and improving system durability. The clear wiring and connection path simplifies system inspection and maintenance, reducing maintenance costs. With a stable power supply, the second magnetic field device can perform its functions more effectively.

[0150] In some embodiments, different first magnetic field devices 610 are connected in series to an electrical connection 920 via a first connector.

[0151] In other embodiments, there are multiple first connectors. Each first magnetic field device 610 is connected to the electrical connection 920 via a first connector. Different first magnetic field devices 610 are connected in parallel. In this way, the current of different first magnetic field devices 610 can be adjusted to generate magnetic fields of different magnitudes.

[0152] As one feasible implementation method, refer to Figure 7 As shown, the refrigerator 100 also includes a second magnetic shield 810, which is located in the mounting cavity and is disposed on the side of the first magnetic field device 610 away from the cover 320.

[0153] For example, a first magnetic field device 610 is provided between the second magnetic shield 810 and the cover 320. The second magnetic shield 810 provides additional protection for the first magnetic field device 610, preventing the first magnetic field device 610 from being physically damaged and ensuring that the first magnetic field device 610 will not move or fall off during use.

[0154] The second magnetic shield 810 can be connected to the cover 320 via fasteners such as screws. Screw holes are machined into the cover 320 and the second magnetic shield 810. The second magnetic shield 810 and the cover 320 are connected by screws passing through the screw holes. Washers can also be used to increase the stability of the connection and prevent loosening.

[0155] The second magnetic shield 810 can also be connected to the cover 320 via a snap-fit ​​connection. During installation, align the snaps on the second magnetic shield 810 with the positioning grooves or holes on the cover 320, and push the snaps into the grooves to achieve the connection between the second magnetic shield 810 and the cover 320.

[0156] The second magnetic shield 810 comprises a silicon steel component. The second magnetic shield 810 can be a mounting cover made of silicon steel. The silicon steel cover has a magnetic shielding effect, thus the second magnetic shield 810 helps to concentrate the magnetic field within the receiving cavity of the vacuum drawer 300, thereby improving its effectiveness. Furthermore, the refrigerator 100 may contain various electronic components and sensors that may be sensitive to magnetic fields. By using the first mounting component 210 with magnetic shielding, these components can be protected from the influence of magnetic fields, ensuring the normal operation of the refrigerator 100.

[0157] As one possible implementation, the refrigerator 100 also includes a third magnetic shield, which is located in the mounting cavity and disposed on the side of the second magnetic field device away from the drawer body 310.

[0158] For example, a second magnetic field device is provided between the third magnetic shield and the drawer body 310. The third magnetic shield provides additional protection for the second magnetic field device, preventing the second magnetic field device from being physically damaged and ensuring that the second magnetic field device will not move or fall off during use.

[0159] The third magnetic shield can be connected to the drawer body 310 using fasteners such as screws. Screw holes are machined into both the drawer body 310 and the third magnetic shield. Screws are passed through these screw holes to connect the third magnetic shield to the drawer body 310. Washers can also be used to increase the stability of the connection and prevent loosening.

[0160] The third magnetic shield can also be connected to the cover 320 via a snap-fit ​​connection. During installation, align the snaps on the third magnetic shield with the positioning slots or holes on the drawer body 310, and push the snaps into the slots to connect the third magnetic shield to the cover 320.

[0161] The third magnetic shielding component includes a silicon steel component. The third magnetic shielding component can be a mounting cover made of silicon steel. The silicon steel cover has a magnetic shielding effect, thus the third magnetic shielding component helps to concentrate the magnetic field within the receiving cavity of the vacuum drawer 300, thereby improving its effectiveness. Furthermore, the refrigerator 100 may contain various electronic components and sensors that may be sensitive to magnetic fields. By using the first mounting component 210 with magnetic shielding, these components can be protected from the influence of magnetic fields, ensuring the normal operation of the refrigerator 100.

[0162] As one feasible implementation method, refer to Figure 10 As shown, the magnetic field device includes:

[0163] The magnetic element 620 is positioned close to the receiving cavity along the height direction of the refrigerator 100, and is used to generate a magnetic field.

[0164] A fastener 630 is provided on the side of the magnetic element 620 opposite to the drawer body 310; the fastener 630 is used to fix the magnetic element 620.

[0165] The first magnetic shield 640 is disposed on the side of the fixing member 630 away from the magnetic element 620; the first magnetic shield 640 is used to shield the magnetic field away from the direction of the receiving cavity.

[0166] Exemplarily, the magnetic element 620 is the core component for generating the magnetic field. The magnetic element 620 is located close to the receiving cavity to ensure that the magnetic field can effectively act on the desired area. The magnetic element 620 includes an electromagnetic coil and a permanent magnet.

[0167] An electromagnetic coil generates a magnetic field when energized, and the strength of this magnetic field can be controlled by adjusting the current. The strength and direction of the electromagnetic coil's magnetic field can be precisely controlled by adjusting the magnitude and direction of the current.

[0168] Permanent magnets provide a continuous magnetic field and can generate a stable magnetic field without the need for an external power source. Because they do not require a power source, permanent magnets do not consume energy when providing a magnetic field.

[0169] The fastener 630 is used to securely mount the magnetic element 620 in the first mounting slot of the cover 320 or the second mounting slot of the drawer body 310, ensuring its stable position. The fastener 630 can be a fixed cover.

[0170] The first magnetic shielding component 640 is disposed on the side of the fixing component 630 opposite to the magnetic element 620, and is mainly used to shield unwanted magnetic field directions, especially those opposite to the receiving cavity. Magnetic shielding materials include silicon steel, which has high magnetic permeability and can effectively guide and shield magnetic fields. By shielding unwanted magnetic field directions, the first magnetic shielding component 640 can prevent magnetic fields from interfering with other components of the refrigerator 100 or the external environment, thereby improving the overall performance and safety of the refrigerator 100.

[0171] The combination of magnetic element 620 and first magnetic shield 640 enables directional control of the magnetic field, ensuring that the magnetic field acts only on the desired area. The first magnetic shield 640 effectively reduces unnecessary magnetic field leakage, preventing interference with other electronic equipment or refrigerator 100 components, thus improving system efficiency and safety. Fixture 630 ensures the stable installation of magnetic element 620, preventing displacement or detachment during use.

[0172] As one feasible implementation method, refer to Figure 9 As shown, the refrigerator 100 also includes a rotating component 360, which is disposed on the side of the cover 320 away from the opening of the inner liner 200; the rotating component 360 is used to drive the cover 320 to rotate relative to the drawer body 310.

[0173] A mounting part is provided on the side of the drawer body 310 opposite to the opening of the inner liner 200.

[0174] The rotating part 360 and the mounting part are rotatably connected along the height direction perpendicular to the refrigerator 100.

[0175] For example, the rotating component 360 is used to rotate the lid 320 relative to the drawer body 310, allowing the user to easily open or close the lid 320 for convenient access to food. The design of the rotating component 360 makes it easy for the user to operate the lid 320, improving the usability of the refrigerator 100. The secure connection between the rotating component 360 and the mounting part ensures the stability of the lid 320 during rotation, reducing shaking and wear.

[0176] In some embodiments, the rotating member 360 is a rotating shaft. The rotating shaft is located on the side of the cover 320 opposite to the opening of the inner liner 200. Figure 1 In the direction shown in the middle Y, a rotating shaft is provided on each side of the cover 320. One end of the rotating shaft is fixedly connected to the cover 320, and the other end of the rotating shaft is rotatably connected to the mounting part.

[0177] The mounting section has a mounting hole for the main body, and one end of the rotating shaft is fixedly connected to the cover. The other end of the rotating shaft is rotatably connected to the drawer body 310 through the mounting hole. At the same time, a sealing plug is provided at this end of the rotating shaft to seal the rotation point and facilitate the removal of the cover.

[0178] The cover 320 is equipped with a lifting handle, which users can use to open the cover 320.

[0179] In some embodiments, the rotating shaft is made of metal, such as a stainless steel shaft. The first connector can be connected to the rotating shaft, and the rotating shaft is also connected to the electrical connection part 920.
