A magnetic field is generated by a magnetic field generator and acts on the items to be refrigerated placed in the storage drawer to preserve the items to be refrigerated. In order to have a corresponding magnetic field device in each cavity, a large number of magnetic field devices are required, which results in high costs.

[0083] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. All other obtained embodiments are within the scope of protection of this application. In the absence of conflict, the following embodiments and features can be combined with each other.

[0084] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0085] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0086] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0087] Currently, refrigerators are not only the main appliances for storing food, but also undertake certain food processing functions. In order to improve the preservation effect, magnetic field devices are installed in refrigerators. The magnetic field generated by the magnetic field generator acts on the items to be refrigerated in the storage drawers to preserve the items, but the preservation effect is still relatively poor.

[0088] Specifically, existing designs typically provide a fixed magnetic field strength, which cannot be adjusted according to the characteristics of different foods or types of bacteria. Some bacteria or molds may be more sensitive to a specific magnetic field strength, while others require a stronger or weaker magnetic field to effectively inhibit their growth. Due to the slight differences in temperature and humidity that may exist inside the drawer, a fixed magnetic field strength may not provide a consistent preservation effect throughout the drawer.

[0089] Furthermore, to improve preservation, dividers are added inside the drawers to create multiple compartments vertically. Multiple magnetic field devices are installed on the top and bottom of the drawers. These devices generate magnetic fields that act on the items to be refrigerated within the drawers, thus preserving their freshness. However, to accommodate a magnetic field device in each compartment, a large number of devices are required, resulting in high costs. Moreover, because the magnetic field strength cannot be adjusted for the characteristics of different foods, the preservation effect may be poor for some items, affecting their freshness, taste, and nutritional value. Therefore, existing refrigerator vacuum drawers suffer from problems such as poor preservation performance and high preservation costs.

[0090] To overcome the shortcomings of the prior art, the refrigerator provided in this application divides the main compartment into multiple sub-compartments using dividers, allowing users to store various types of food or items according to the different preservation levels of each sub-compartment. Simultaneously, magnetic field devices are installed on the dividers and vacuum drawers, designed to generate different gas field intensities. Users can adjust the magnetic field intensity of each sub-compartment according to the characteristics of different items and their preservation needs, thereby optimizing the environmental conditions of each sub-compartment, extending the preservation time of food in multiple sub-compartments, improving food freshness, and resulting in a better user experience.

[0091] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

Figure 6 This is a schematic diagram of the assembly of the drawer body and the first magnetic field device in a refrigerator according to an embodiment of this application.

[0093] like Figures 1 to 6 As shown, this application embodiment provides a refrigerator 100, including:

[0094] The inner liner is 200mm and has a storage compartment;

[0095] Vacuum drawer 300, movably located in the storage compartment, has a receiving cavity;

[0096] A partition 340 is disposed within the vacuum drawer 300 to divide the receiving cavity into at least two sub-receiving cavities 330;

[0097] At least two magnetic field devices 600, at least one magnetic field device 600 is disposed on the partition 340, and at least one magnetic field device 600 is disposed on the periphery of the vacuum drawer 300;

[0098] At least two magnetic field devices 600 are configured to generate different magnetic field strengths to provide magnetic fields of different strengths to at least two sub-receiving cavities 330.

[0099] With the above-described configuration, the refrigerator 100 of this embodiment divides the storage cavity into multiple sub-cavities 330 using the divider 340, allowing users to store various types of food or items according to the different preservation levels of the sub-cavities 330. Simultaneously, magnetic field devices 600 are respectively installed on the divider 340 and the vacuum drawer 300. These magnetic field devices 600 are designed to generate different gas field intensities. Users can adjust the magnetic field intensity of each sub-cavity 330 according to the characteristics of different items and their preservation needs, thereby optimizing the environmental conditions of each sub-cavity 330. This extends the preservation time of food in the multiple sub-cavities 330, improves the freshness of the food, and provides a better user experience.

[0100] It should be noted that the following provides a detailed explanation of each structure.

[0101] [Box 101]

[0102] The refrigerator 100 of this application embodiment may include a cabinet 101 and a door 102. The cabinet 101 may be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. There may be one or more refrigeration compartments. When there are multiple refrigeration compartments, the multiple refrigeration compartments may be divided into a refrigerator compartment, a freezer compartment, or a variable temperature compartment, etc.

[0103] For example, the refrigerator body 101 may include an outer shell and an inner liner 200, the outer shell defining the external boundary of the refrigerator 100. The inner liner 200 may be disposed within the outer shell and connected to it. The inner liner 200 may be recessed inward to form a cooling compartment, i.e., a storage compartment. An insulation layer may be filled between the outer shell and the inner liner 200, which can insulate the cooling compartment, thereby reducing the energy consumption of the refrigerator 100.

[0104] The box 101 adopts a hollow cuboid structure. It is understood that in other embodiments, the box 101 may also adopt a hollow shell structure of other shapes.

[0105] In some embodiments, a refrigeration assembly (not shown) is provided inside the cabinet 101 to provide refrigeration for the interior of the refrigerator 100 in order to maintain a low-temperature environment in each refrigeration compartment.

[0106] Refrigeration components include compressors, condensers, evaporators, and throttling devices. The specific structure and connections of these components can be found in relevant technical documentation on refrigeration components, and will not be elaborated upon here. The evaporator provides different amounts of cooling capacity to different types of storage spaces, resulting in varying temperatures within these spaces. For example, the temperature inside a refrigerator is generally between 2°C and 10°C, preferably between 4°C and 7°C. The temperature range inside a freezer is generally between -22°C and -14°C. Different types of items have different optimal storage temperatures, and consequently, different suitable storage spaces. For example, fruits and vegetables are suitable for storage in refrigerators or crisper compartments, while meat is suitable for storage in freezers.

[0107] [Gate 102]

[0108] It should be noted that the door 102 can be connected to the cabinet 101 to open or close the refrigeration compartment.

[0109] A door 102 is disposed on the front surface of the enclosure 101 to enclose the refrigeration compartment. The door 102 is configured to open and close the refrigeration compartment, meaning it can open and close the front opening of the enclosure 101. Doors 102 can be correspondingly arranged with refrigeration compartments; that is, each refrigeration compartment corresponds to one or more doors 102. The number of refrigeration compartments and doors 102, as well as the function of the refrigeration compartments, can be selected based on specific circumstances. One door 102 can be provided for the same refrigeration compartment. Alternatively, two doors 102 can be provided for the same refrigeration compartment.

[0110] In some possible implementations of this application, the door 102 can be rotatably connected to the housing 101 about the height direction Y of the housing 101. The door 102 can be pulled or pushed to rotate relative to the housing 101, thereby opening or closing the refrigeration compartment.

[0111] In some embodiments, the door 102 is a rotating door structure. The door 102 is rotatably disposed on the front side of the cabinet 101, and in this case, the door 102 can be used as a general door structure, such as a refrigerator door, a freezer door, etc.

[0112] Specifically, the door 102 and the cabinet 101 can be connected by a hinge so that the door 102 of the refrigerator 100 can rotate around the axis of the hinge, thereby opening and closing the door 102 of the refrigerator 100 and opening and closing the corresponding refrigeration compartment.

[0113] In some embodiments, the door 102 can also be a sliding door structure. The door 102 is slidably disposed on the front side of the cabinet 101, and in this case, the door 102 can be used as a drawer door. Specifically, guide rails (not shown in the figure) are respectively provided on the left and right inner side walls of the cabinet, and the door 102 is connected to the guide rails on both sides, thereby realizing the sliding function of the door 102 and realizing the opening and closing of the refrigeration compartment by extending and retracting the guide rails.

[0114] [Vacuum Drawer 300]

[0115] It should be noted that the refrigerator 100 provided in this application embodiment also includes a vacuum drawer 300, wherein the vacuum drawer 300 is movably disposed in the storage compartment and has a receiving cavity for receiving items to be refrigerated, which may include multiple types of items.

[0116] For example, multiple categories of items may include a first category of items, a second category of items, a third category of items, and a fourth category of items. The first category of items may be fruits, the second category of items may be vegetables, the third category of items may be fresh meat, and the fourth category of items may be fungi.

[0117] It is understood that the items to be refrigerated can also be other types of items, which will not be elaborated further in this application embodiment.

[0118] In some embodiments, the vacuum drawer 300 can be pushed and pulled relative to the storage compartment. When pulled out, it is convenient for the user to take out the items to be refrigerated, and when pushed in, it can store the items to be refrigerated.

[0119] In some embodiments, the vacuum drawer 300 includes a drawer body 310 and a cover 320, the drawer body 310 having an opening and the cover 320 being disposed at the opening.

[0120] In some embodiments, the drawer body 310 is pull-out relative to the inner liner 200, allowing it to be pulled out or pushed into the storage compartment. A lid 320 closes onto the opening of the drawer body 310, ensuring that the vacuum environment within the drawer body 310 is not disrupted and providing a sealing function to enhance the vacuum effect.

[0121] In some embodiments, the front side of the drawer body 310 is provided with a drawer panel 350, which can serve as an exterior panel. The drawer panel 350 is provided with a force-applying part, which allows the user to apply force to open the drawer body 310.

[0122] [Separator 340]

[0123] It should be noted that the refrigerator 100 provided in this application embodiment also includes a divider 340, which is disposed in the vacuum drawer 300 to divide the accommodating cavity into at least two sub-accommodating cavities 330.

[0124] In some embodiments, there are two partitions 340 in this application to divide the receiving cavity into four receiving cavities, specifically, but again without excessive limitation.

[0125] It should be noted that multiple sub-cavities 330 are formed by the separator 340, and these multiple sub-cavities 330 form multiple storage areas. Users can classify and place items to be refrigerated in different storage areas for refined storage.

[0126] For example, 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 may be used to accommodate first-class articles, the second storage area may be used to accommodate second-class articles, the third storage area may be used to accommodate third-class articles, and the fourth storage area may be used to accommodate fourth-class articles.

[0127] In some embodiments, the divider 340 is connected to the side wall of the vacuum drawer 300 by fasteners such as screws.

[0128] The screw connection provides enhanced stability, ensuring that the divider 340 will not easily move or detach during use. The divider 340 divides the accommodating cavity into multiple sub-accommodating cavities 330, 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.

[0129] For example, the divider 340 is a partition that divides the vacuum drawer 300 into multiple sub-receiving cavities 330, i.e. multiple storage areas.

[0130] In some alternative embodiments, there are at least two spacers 340, and the at least two spacers 340 include:

[0131] The first divider 341 is located in the middle of the vacuum drawer 300 along the width direction of the refrigerator 100;

[0132] The second divider 342 is located in the middle of the vacuum drawer 300 along the depth direction of the refrigerator 100;

[0133] The first partition 341 and the second partition 342 are arranged in an intersecting manner to form at least four sub-accommodating cavities 330.

[0134] The above technical solution has the following advantages or beneficial effects: by dividing the interior of the drawer into multiple sub-cavities 330, space can be utilized more effectively. Each sub-cavity 330 can independently store different items, avoiding item stacking and improving the orderliness and tidiness of storage.

[0135] Users can categorize and store different ingredients or items in different sub-containment cavities 330 according to their characteristics.

[0136] The dividers 340 help reduce cross-contamination of odors and liquids between different ingredients, preserving the original flavor and quality of each ingredient. The cross-shaped dividers 340 provide additional structural support, enhancing drawer stability and preventing items from tipping over or sliding when the drawer is opened and closed.

[0137] In some embodiments, the divider 340 is detachably connected to the vacuum drawer 300, allowing the user to adjust the size and shape of the sub-receiving cavity 330 according to actual needs, increasing storage flexibility and adaptability.

[0138] The at least four sub-cavities 330 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 store first-class articles, the second storage area can be used to store second-class articles, the third storage area can be used to store third-class articles, and the fourth storage area can be used to store fourth-class articles.

[0139] [Vacuum device 400]

[0140] It should be noted that the refrigerator 100 provided in this application embodiment also includes a vacuum device 400. The vacuum drawer 300 forms an independent sealed space, i.e., a receiving cavity, inside the refrigerator 100. The vacuum device 400 can extract the air inside the vacuum drawer 300, reduce the internal air pressure, thereby reducing the oxygen content in the vacuum drawer 300, delaying the oxidation of food and the growth of bacteria, and achieving a longer preservation effect.

[0141] It should be noted that the vacuum environment of the Vacuum Drawer 300 inhibits food oxidation and reduces moisture loss, keeping fruits, vegetables, meats, and other ingredients fresh for a longer period. Vacuum preservation better retains the vitamins, minerals, and other nutrients in food, avoiding nutrient loss caused by oxidation.

[0142] In some embodiments, the vacuum device 400 is connected to the vacuum drawer 300 for adjusting the vacuum level of the receiving cavity. The vacuum device 400 can adjust the vacuum level of each sub-receiving cavity 330 according to the storage requirements of different items, thereby achieving a personalized storage environment.

[0143] In some embodiments, the vacuum device 400 includes a pump body 410, a suction line 420, and a valve 430. The pump body 410 is responsible for generating suction to reduce the air pressure in the sub-receiving cavity 330. The suction line 420 connects the pump body 410 and the sub-receiving cavity 330 and is used to transmit the suction effect generated by the pump body 410.

[0144] Valve 430 is used to control the opening and closing of the vacuum line 420, thereby adjusting the vacuum level of the sub-containment chamber 330. Through valve 430, the user can precisely adjust the vacuum level of each sub-containment chamber 330 to meet the preservation needs of different items.

[0145] Since users will need to open the vacuum drawer 300 from the top to retrieve food stored in the compartment, the vacuum management system is located at the bottom of the vacuum drawer 300 to optimize the internal space layout of the refrigerator 100 and avoid interfering with the user's daily operations.

[0146] It should be noted that different types of food or items have different requirements for storage conditions. Some foods may require a higher degree of vacuum to reduce oxidation and bacterial growth, while others may require a lower degree of vacuum to avoid spoilage.

[0147] Therefore, users can selectively adjust the vacuum level of a specific sub-cavity 330, rather than the entire drawer. This selective adjustment can reduce unnecessary energy consumption and improve energy efficiency.

[0148] In some embodiments, there may be four sub-cavities 330 in this application embodiment. Therefore, there may also be four valves 430. One sub-cavity 330 corresponds to one valve 430. The valve 430 controls the opening and closing of the vacuum pipe 420, thereby adjusting the vacuum degree of the sub-cavity 330 to meet the different vacuum degrees required by each sub-cavity 330.

[0149] The refrigerator 100 provided in this embodiment further includes a pressure relief component 510, which is used to connect the sub-receiving cavity 330 to atmospheric pressure. The number of pressure relief components 510 is consistent with the number of sub-receiving cavities 330.

[0150] For example, the pressure relief element 510 takes the form of a pressure relief valve, which can establish a channel between the sub-receiving cavity 330 and the external atmosphere to balance the internal and external pressures. The pressure relief element 510 can be a pressure relief valve. The user can release the vacuum pressure in the cavity by simply pressing the pressure relief valve, so that the internal pressure is balanced with the external atmospheric pressure.

[0151] With the pressure relief component 510, the process of removing food is simple and intuitive for users; they only need to press a button to release pressure. The pressure relief valve ensures that the internal pressure is balanced before opening the drawer, preventing accidental opening or damage due to pressure differences.

[0152] [Magnetic field device 600]

[0153] It should be noted that the refrigerator 100 provided in this application embodiment also includes a magnetic field device 600, which is configured to generate a magnetic field and apply the magnetic field to the item to be cooled.

[0154] The magnetic field acting on the item being refrigerated can influence gene expression, alter cell membrane permeability, and reduce the metabolic rate of the item. The magnetic field can also form more hydrogen bonds, reducing weight loss and fluid loss, and delaying tissue softening. Furthermore, it can eliminate hydrogen peroxide and superoxide free radicals in the item, protecting its cells from oxidative damage and thus preserving its freshness. In addition, the strong penetrating power of the magnetic field can effectively penetrate various packaging materials; when users wrap the item in packaging before storing it in the refrigerator, it still maintains good preservation.

[0155] In some embodiments, there are at least two magnetic field devices 600, with at least one magnetic field device 600 disposed on the outer periphery of the vacuum drawer 300 and at least one magnetic field device 600 disposed on the separator 340. By adjusting the magnitude of each magnetic field strength, the magnetic field strength in each sub-cavity 330 can be made different. In this way, the magnetic field strength of each sub-cavity 330 can be adjusted separately according to the storage requirements of different items, thereby achieving a personalized storage environment.

[0156] In other words, the magnetic field strengths corresponding to the first, second, third, and fourth storage zones are all different, which allows for more targeted preservation and storage based on the type of food, resulting in higher freshness.

[0157] Specifically, users can adjust the vacuum level and magnetic field strength of each sub-cavity 330 according to the characteristics and storage needs of different items. This flexibility allows the refrigerator 100 to store various types of food or items more efficiently. By providing independent vacuum and magnetic field control, users can optimize the environmental conditions of each sub-cavity 330, thereby extending the preservation time and improving the storage quality.

[0158] Different magnetic field intensities can produce different preservation effects on different types of food. For example, some foods are better preserved under a stronger magnetic field, while others may be better preserved under a weaker magnetic field. By adjusting the magnetic field strength, the shelf life of food can be extended more effectively. Users can select the appropriate sub-containment cavity 330 and the corresponding magnetic field strength according to the characteristics of the stored items, thereby providing a customized storage environment for different foods and optimizing their preservation conditions.

[0159] In some alternative embodiments, at least two magnetic field devices 600 include:

[0160] The first magnetic field device 610 is located along the pulling direction of the vacuum drawer 300, with a portion of the first magnetic field device 610 located on the front side of the vacuum drawer 300 and another portion located on the rear side of the vacuum drawer 300.

[0161] The second magnetic field device 620 is disposed on the first side of the first partition 341, and the first side of the first partition 341 faces the rear side of the vacuum drawer 300.

[0162] The first magnetic field device 610 and the second magnetic field device 620 are arranged at intervals along the pull-out direction of the vacuum drawer 300.

[0163] The above technical solution has the following advantages or beneficial effects: by the cooperation of the second magnetic field device 620 set in the separator 340 and the first magnetic field device 610 set in the vacuum drawer 300, directional magnetic field control of a specific area can be achieved, allowing magnetic fields of different intensities or properties to be applied in different sub-containment cavities 330 to meet the preservation needs of different ingredients, thereby improving the preservation effect of the ingredients in the containment cavity.

[0164] It should be noted that the first magnetic field device 610 is located on the front and rear sides of the drawer. Since the magnetic field strength generated by the magnetic field devices 600 located on different sides is the strongest and provides the best preservation effect, considering the large distance between the front and rear sides of the vacuum drawer 300, a second magnetic field device 620 needs to be installed on the divider 340 in the middle of the vacuum drawer 300.

[0165] By optimizing the distribution and intensity of the magnetic field, the refrigerator 100 can reduce energy consumption and improve energy efficiency without affecting the preservation effect. Different magnetic field intensities and distributions can produce different preservation effects on food, extending its freshness and maintaining its flavor and nutrients.

[0166] It should be noted that, along the depth direction of the refrigerator 100, at least the first magnetic field device 610 and the second magnetic field device 620 are arranged in a one-to-one correspondence. This correspondence allows for independent and precise control of the magnetic field of each sub-cavity 330, ensuring that the magnetic field strength and distribution of each sub-cavity 330 meet specific storage requirements. Users can flexibly adjust the strength of each pair of magnetic field devices 600 according to different storage needs, thereby achieving a personalized storage environment.

[0167] Figure 7 This is a first-view exploded view of the refrigerator drawer body and the first type of magnetic field device provided in an embodiment of this application. Figure 8 An exploded view of the refrigerator drawer body and the first magnetic field device provided in the embodiments of this application from a second perspective.

[0168] like Figures 1 to 8As shown, in some embodiments, the first magnetic field device 610 includes a first magnetic element 611 disposed on the front side of the vacuum drawer 300. The first magnetic field device 610 also includes a second magnetic element 612 disposed on the rear side of the vacuum drawer 300.

[0169] In some embodiments, the second magnetic field device 620 includes a third magnetic element 621 and a fourth magnetic element 622. The third magnetic element 621 is disposed on the first side of the first partition 341, and the fourth magnetic element 622 is disposed on the first side of the first partition 341. The fourth magnetic element and the third magnetic element are located in different sub-accommodating cavities 330, wherein the first side of the first partition 341 faces the rear side of the vacuum drawer 300.

[0170] It should be noted that by placing one magnetic device at each of the front, middle, and rear positions of the vacuum drawer 300, only four magnetic field devices 600 are needed to achieve adjustable magnetic field strength within the area. This reduces the number of magnetic field devices 600 by at least four compared to installing magnetic field devices 600 both above and below the vacuum drawer 300. In some embodiments, the magnetic element is the core component for generating the magnetic field. The magnetic element is positioned close to the receiving cavity to ensure that the magnetic field can effectively act on the desired area.

[0171] In some embodiments, the magnetic field device 600 further includes a magnetic shielding element disposed on the magnetic element, which is mainly used to shield unwanted magnetic field directions, especially those away from the receiving cavity.

[0172] In some embodiments, the magnetic shielding component is made of materials such as silicon steel, which have high magnetic permeability and can effectively guide and shield magnetic fields. By shielding unwanted magnetic field directions, the magnetic shielding component 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. The magnetic shielding component can be a silicon steel plate.

[0173] In addition, the magnetic shielding provides extra protection for the magnetic components, preventing them from being physically damaged and ensuring that they do not move or fall off during use.

[0174] By combining magnetic components and magnetic shielding, the directional control of the magnetic field can be achieved, ensuring that the magnetic field acts only on the desired area. Magnetic shielding effectively reduces unnecessary magnetic field leakage, preventing interference with other electronic equipment or refrigerator components, and improving system efficiency and safety.

[0175] like Figure 7 and Figure 8 As shown, in some embodiments, the first magnetic element 611 is provided with a first magnetic shield 630 and the second magnetic element 612 is provided with a second magnetic shield 640.

[0176] In order to better protect the third magnetic element 621 and the fourth magnetic element 622, in some embodiments, the third magnetic element 621 is provided with a first protective cover 650 and the fourth magnetic element 622 is provided with a second protective cover 660.

[0177] like Figures 5 to 8 As shown, in some alternative embodiments, at least one of the at least two magnetic field devices 600 is a permanent magnet, and the thickness of the permanent magnet corresponding to each sub-receiving cavity 330 is different.

[0178] It should be noted that when the magnetic field device 600 is a permanent magnet, the magnetic field strength in each sub-cavity 330 can be adjusted by changing the thickness of the permanent magnet located in each sub-cavity 330.

[0179] In some embodiments, at least four sub-receiving cavities 330 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 articles, the second storage area can be used to accommodate second-class articles, the third storage area can be used to accommodate third-class articles, and the fourth storage area can be used to accommodate fourth-class articles.

[0180] Among them, the first category of items can be fresh food, the second category of items can be vegetables, the third category of items can be fruits, and the fourth category of items can be rare and precious food.

[0181] For fresh food, the corresponding geomagnetic field strength range is 0.1-2 mT. Within this range, microbial growth can be inhibited. Conversely, when the magnetic field strength is below 0.1 mT, the effect may be insignificant. And when the magnetic field strength is above 2 mT, the excessively high strength may affect the chemical properties of the food.

[0182] For vegetables, the corresponding geomagnetic field strength range is 0.1-3 mT. Within this range, enzymatic reactions are slowed down, maintaining freshness. Conversely, when the magnetic field strength is less than 0.1 mT, the effect may be insignificant. And when the magnetic field strength is greater than 3 mT, the effect may negatively impact cell structure.

[0183] For fruits, the corresponding geomagnetic field strength range is 0.1-2.5 mT. Within this range, enzymatic reactions are slowed down, maintaining freshness. Conversely, when the magnetic field strength is less than 0.1 mT, the effect may be insignificant. And when the magnetic field strength is greater than 2.5 mT, the effect may negatively impact cell structure.

[0184] For premium ingredients, the corresponding geomagnetic field strength range is 0.1-4 mT. Within this range, the magnetic field strength helps maintain quality. Conversely, when the magnetic field strength range is less than 0.1 mT, the low magnetic field strength may have no significant effect. And when the magnetic field strength range is greater than 4 mT, the high magnetic field strength may adversely affect chemical properties.

[0185] It should be noted that the thickness of the permanent magnet can be 0-1mm, 1-2mm, 2-3mm, 3-4mm, or greater than 4mm.

[0186] Among them, permanent magnets with a diameter of 0-1 mm can generate a magnetic field strength of 0-0.5 mT, permanent magnets with a diameter of 1-2 mm can generate a magnetic field strength of 0.5-1.5 mT, permanent magnets with a diameter of 3-4 mm can generate a magnetic field strength of 3-4 mT, and permanent magnets with a diameter greater than 4 mm can generate a magnetic field strength greater than 4 mT.

[0187] Based on the above, in some embodiments, permanent magnets with thicknesses of 1 mm and 2 mm can be respectively disposed on the first partition, and permanent magnets with thicknesses of 3 mm and 3.5 mm can be respectively disposed on the rear side and front side of the vacuum drawer 300. The 1 mm thick permanent magnet faces the first storage area, and the 2 mm thick permanent magnet faces the third storage area. Therefore, the first storage area, the second storage area, the third storage area, and the fourth storage area are arranged clockwise along the front side of the vacuum drawer 300. The above technical solution has the following advantages or beneficial effects: the permanent magnets can provide a continuous and stable magnetic field, without the need for an external power source to maintain the magnetic field strength, ensuring that the refrigerator 100 can still provide a certain preservation effect in power outage or low energy consumption mode.

[0188] Since permanent magnets do not require electricity to maintain their magnetic field, their use reduces the overall energy consumption of refrigerator 100, helping to improve energy efficiency and reduce operating costs. Permanent magnets typically have a long service life and high reliability, reducing maintenance needs and replacement frequency, thereby lowering the maintenance costs of refrigerator 100.

[0189] Using permanent magnets simplifies the design of the magnetic field device 600 because it eliminates the need for complex circuitry and control systems to maintain the magnetic field, which helps reduce manufacturing costs and improve product reliability.

[0190] In some embodiments, the magnetic field strength of the permanent magnet is adjusted by adjusting the thickness and size of the permanent magnet. Therefore, permanent magnets of different thicknesses or sizes can be set at different locations to meet different magnetic field strengths within each sub-receiving cavity 330.

[0191] [Power Supply Component 700]

[0192] Figure 9This is a schematic diagram of the structure of a drawer in a refrigerator provided in an embodiment of this application. Figure 10 This is an exploded view of the assembly of the second type of vacuum drawer and drawer bucket in a refrigerator provided in an embodiment of this application. Figure 11 for Figure 10 A magnified view of a portion of point I in the middle. Figure 12 This is a schematic diagram of the structure of the second type of vacuum drawer in a refrigerator provided in an embodiment of this application. Figure 13 This is an explosion diagram of the second type of vacuum drawer in a refrigerator provided in an embodiment of this application. Figure 14 This is a schematic diagram of the assembly of the drawer body and the second magnetic field device in a refrigerator according to an embodiment of this application. Figure 15 This is a first-view exploded view of the assembly of the drawer body and the second magnetic field device in a refrigerator, provided in an embodiment of this application. Figure 16 for Figure 15 A magnified view of a portion of section II. Figure 17 An exploded view of the refrigerator drawer body and the second magnetic field device from a first perspective, provided in an embodiment of this application.

[0193] In some alternative embodiments, at least one of the at least two magnetic field devices 600 is an electromagnet, and the number of coil turns of the electromagnet corresponding to each sub-receiving cavity is different.

[0194] The magnetic field strength of an electromagnet can be controlled by adjusting the current, allowing users to adjust the preservation of different foods according to their needs.

[0195] It should be noted that a significant advantage of electromagnets is that their magnetic field strength can be controlled by adjusting the current, allowing users to flexibly adjust the magnetic field strength according to the preservation needs of different foods, thereby optimizing the preservation effect.

[0196] The electromagnet can be turned on or off as needed, allowing the refrigerator 100 to flexibly adjust the range and intensity of the magnetic field in different operating modes to adapt to diverse storage needs. By precisely controlling the magnetic field strength, the electromagnet can provide a customized magnetic field environment for specific sub-cavities 330, potentially resulting in better preservation of certain foods and extending their freshness.

[0197] Although electromagnets require electricity to maintain their magnetic field, their controllability allows for reducing the current or turning off the electromagnet when a strong magnetic field is not needed, thus saving energy. Electromagnets can be integrated with the refrigerator's intelligent control system to achieve automated magnetic field adjustment.

[0198] It should be noted that the magnetic field device 600 inside the refrigerator 100 can be entirely made of permanent magnets or entirely made of electromagnets, or part of it can be made of permanent magnets and the other part of it can be made of electromagnets. No further restrictions will be placed here.

[0199] It should be noted that the number of coil turns corresponding to a magnetic field strength of 0-0.5mT is 10-600, the number of coil turns corresponding to a magnetic field strength of 0.5-1.5mT is 600-1500, the number of coil turns corresponding to a magnetic field strength of 1.5-3mT is 1500-2000, the number of coil turns corresponding to a magnetic field strength of 3-4mT is 2000-3000, and the number of coil turns corresponding to a magnetic field strength greater than 4mT is >3000.

[0200] Based on the analysis of the four different types of food, electromagnets with 500 and 1000 coil turns can be respectively installed in the first partition, and electromagnets with 1500 and 2000 coil turns can be respectively installed on the rear and front sides of the vacuum drawer 300, with the electromagnet with 500 coil turns facing the first storage area and the electromagnet with 1000 coil turns facing the third storage area. In some optional embodiments, when at least one of the at least two magnetic field devices 600 is an electromagnet, the refrigerator 100 also includes a power supply assembly 700, which includes a first power supply component 710 located at the intersection of the first partition 341 and the second partition 342. The first power supply component 710 is configured to supply power to the magnetic field devices 600 located at different positions in the vacuum drawer 300.

[0201] The power supply assembly 700 includes a controller, which is electrically connected to the first power supply component 710. The controller is used to control the power supply current of the first power supply component 710 to control the magnetic field strength of the magnetic field device 600.

[0202] In some optional implementations, the controller is used to control the supply current of the first power supply element to control the magnetic field strength of the magnetic field device, specifically including:

[0203] The controller determines the magnetic field range of each sub-cavity 330 based on the food stored in each sub-cavity 330, and at least two sub-cavities 330 have different magnetic field ranges;

[0204] The controller has at least two control terminals, which control the power supply current supplied to the electromagnet within the sub-receiving cavity 330;

[0205] It also includes multiple detectors, which are used to detect the magnetic field strength of the sub-cavity and transmit the detection signal to the control terminal. The control terminal controls the magnitude of the power supply current supplied to the electromagnet based on the difference between the detection signal and the magnetic field range of the corresponding sub-cavity 330.

[0206] The above technical solution has the following advantages or beneficial effects: the first power supply component 710 is located in the intersection area of ​​the first partition 341 and the second partition 342, which can effectively supply power to the magnetic field device 600 located in different positions in the vacuum drawer 300. This centralized power supply management simplifies the circuit design and improves the power supply efficiency.

[0207] By electrically connecting the controller to the first power supply unit 710, the user can precisely control the power supply current, thereby adjusting the magnetic field strength of the electromagnet, allowing for customized magnetic field environments for different sub-cavities 330, and optimizing the preservation effect of food.

[0208] This application enables precise control of the magnetic field strength within each sub-cavity 330, thereby optimizing food storage conditions and extending shelf life. Through the controller's intelligent adjustment function, different foods can be stored under their optimal magnetic field strength, reducing spoilage or nutrient loss caused by improper magnetic fields. Furthermore, the detector monitors the magnetic field strength in real time and feeds the information back to the control unit, allowing the system to dynamically adjust the power supply current, further improving control accuracy and response speed. This independent control method for multiple sub-cavities 330 enhances the flexibility and applicability of the equipment, meeting diverse food storage needs.

[0209] It should be noted that the controller can integrate intelligent algorithms to automatically adjust the magnetic field strength based on sensor data or user settings. This intelligent operation improves the user experience and ensures that food is stored under optimal conditions. Through the controller's adjustment function, the power supply current can be reduced or the electromagnet can be turned off when a strong magnetic field is not needed, thereby achieving energy-saving operation and reducing the refrigerator's overall energy consumption by 100%.

[0210] It should be noted that the magnetic field devices 600 located at different positions in the vacuum drawer 300 may include a second magnetic field device 620 located in different sub-cavities 330, and a first magnetic field device 610 located in the vacuum drawer 300. Specifically, these are a first magnetic element 611, a second magnetic element 612, a third magnetic element 621, and a fourth magnetic element 622.

[0211] In some embodiments, based on the above design that allows for different numbers of coil turns of electromagnets within different sub-cavities 330, once the number of electromagnet turns is determined and the electromagnets are installed, the magnetic field strength of the sub-cavity is detected by a detector. If the detected magnetic field strength meets the preset magnetic field range, there is no need to adjust the power supply current. If the detected magnetic field strength does not meet the preset magnetic field range, the power supply current is increased to meet the magnetic field strength requirements of the sub-cavity 330.

[0212] For example, taking fresh food as an example, after the electromagnet is installed in the sub-receiving cavity 330 for storing fresh food, the detector detects that the strength of the sub-receiving cavity 330 is 0.05. Since the corresponding magnetic field strength range for fresh food is 0.1-2mT, when the detected magnetic field strength of 0.05mT does not reach the preset magnetic field range, the control terminal of the controller controls the power supply current of the first power supply component to make its magnetic field strength meet the 0.1-2mT range.

[0213] In some alternative embodiments, the power supply assembly 700 further includes a second power supply component 720, which is disposed on the rear side of the vacuum drawer 300. The first end of the second power supply component 720 is configured to be connected to the power supply of the refrigerator 100, and the second power supply component 720 is configured to supply power to the magnetic field device 600 located on the rear side of the vacuum drawer 300.

[0214] The second end of the second power supply component 720 is electrically connected to the first power supply component 710.

[0215] The above technical solution has the following advantages or beneficial effects: the first end of the second power supply component 720 is connected to the power supply of the refrigerator 100, ensuring effective power transmission. By directly connecting to the power supply of the refrigerator 100, the second power supply component 720 can provide a stable power supply to the magnetic field device 600 on the rear side of the vacuum drawer 300.

[0216] The second end of the second power supply component 720 is electrically connected to the first power supply component 710, forming a complete power supply network. This integrated design simplifies the circuit layout and improves the overall efficiency and reliability of the system. By connecting the second power supply component 720 to the first power supply component 710, the system can flexibly distribute power to ensure that the magnetic field device 600 at different locations receives the required current.

[0217] It should be noted that when the vacuum drawer 300 is pushed in or pulled out, the second power supply unit 720 automatically connects or disconnects from the power supply of the refrigerator 100, which simplifies the power supply structure and eliminates the need for the user to manually plug or unplug the cable. This greatly simplifies the user operation and improves the ease of use.

[0218] In some alternative embodiments, the first power supply component 710 includes a first power supply section 711, and a first end of the first power supply section 711 is electrically connected to a second end of the second power supply component 720.

[0219] In some alternative embodiments, the first power supply unit 710 includes a second power supply section 712, the first end of which is connected to the second end of the first power supply section 711, and the second end of the second power supply section 712 is electrically connected to magnetic field devices 600 at different positions in the vacuum drawer 300.

[0220] The above technical solution has the following advantages or beneficial effects: the first end of the first power supply unit 711 is electrically connected to the second end of the second power supply component 720, ensuring the power transmission efficiency from the power supply of the refrigerator 100 to the first power supply component 710. The first end of the second power supply unit 712 is connected to the second end of the first power supply unit 711, forming a continuous power transmission path.

[0221] The first power supply component 710 is divided into a first power supply section 711 and a second power supply section 712, which makes the power supply system more modular, easier to manufacture, install and maintain, and improves the system's flexibility and adaptability.

[0222] The second end of the second power supply unit 712 is electrically connected to the magnetic field devices 600 at different locations in the vacuum drawer 300, allowing for flexible distribution of power to each magnetic field device 600. This flexibility supports precise control of the magnetic field strength in different sub-cavities 330, meeting the preservation needs of different foods.

[0223] By segmenting the power supply path, the risk of single-point failures is reduced, improving system reliability and durability. The modular design also makes troubleshooting and maintenance more convenient. This design allows users to flexibly adjust the magnetic field environment according to different storage needs, providing a better user experience and a more efficient food preservation solution.

[0238] For example, the first sealing groove 311 is used to receive the first seal to ensure that when the cover 320 is closed, the seal can make tight contact with the cover 320 to form an effective seal.

[0239] For example, the first seal is made of a soft and elastic material, such as silicone or rubber, to ensure good sealing performance and durability.

[0240] In some alternative embodiments, the refrigerator 100 further includes: a drawer 103 disposed in the inner liner 200, the drawer 103 having a storage compartment, a vacuum drawer 300 being pulled out relative to the drawer 103, the drawer 103 having an opening 1031, at least a portion of the second power supply 720 passing through the opening 1031 and connected to the power supply of the refrigerator 100.

[0241] The power supply assembly 700 also includes:

[0242] The first sealing ring 730 is fitted around the outer periphery of the second power supply part 712 and is located between the cover 320 and the separator 340;

[0243] The second sealing ring 740 is fitted around the outer periphery of the second power supply component 720 and is located between the drawer body 310 and the drawer bucket 103.

[0244] The above technical solution has the following advantages or beneficial effects: The first sealing ring 730 is fitted around the outer periphery of the second power supply unit 712, located between the cover 320 and the separator 340, ensuring good sealing between these components. The second sealing ring 740 is fitted around the outer periphery of the second power supply unit 720, located between the drawer body 310 and the drawer drum 103, further enhancing the sealing performance of the entire drawer system. This sealing design helps maintain a vacuum state in the storage compartment, improving the preservation effect.

[0245] In addition, the vacuum drawer 300 can be pulled out relative to the drawer bucket 103, allowing users to easily access items in the storage compartment.

[0246] By providing an opening 1031 on the drawer 103, the second power supply component 720 can pass through the opening 1031 and connect to the power supply of the refrigerator 100, ensuring efficient power transmission. The design of the opening 1031 makes the installation and maintenance of the second power supply component 720 easier, reduces the complexity of the installation process, and ensures the stability of the electrical connection.

[0247] It should be noted that the sealing ring not only provides airtightness, but also provides additional fixation and protection for the cables passing through it, reducing the risk of loosening or damage to electrical connections due to cable movement or vibration.

Simultaneously, magnetic field devices are installed on the dividers and vacuum drawers, designed to generate different gas field intensities. Users can adjust the magnetic field intensity of each sub-compartment according to the characteristics of different items and preservation needs, thereby optimizing the environmental conditions of each sub-compartment. This extends the preservation time of food within multiple sub-compartments, improves food freshness, and enhances the user experience.
