Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is mainly used to keep food or other items at a constant low temperature so as to keep them fresh and preserve them for a long time. Nowadays, it has entered thousands of households.

[0003] Among them, magnetic field preservation, as an emerging technology in the refrigerator field, works by setting up magnetic components to create a magnetic field in the container cavity, so that chilled meat and other foods are in a magnetic field environment. The magnetic field affects the physical properties and movement of water molecules in the food, as well as inhibits the activity of microorganisms, thereby improving the preservation effect of the food in the container cavity.

[0004] In related technologies, magnetic components are usually placed inside the inner bubble layer, which is inconvenient for later removal and maintenance. Their fixing structure is relatively complex and costly. They are also far away from the food, resulting in poor magnetic field preservation effect. Utility Model Content

[0005] The purpose of this application is to provide a refrigerator that can solve the technical problems of inconvenient magnetic component installation, difficulty in later disassembly and maintenance, and poor preservation effect.

[0006] To solve the above technical problems, this application adopts the following technical solution:

[0008] The above-mentioned technical features have at least the following technical effects:

[0009] By incorporating a magnetic generating assembly, which includes a shell and a magnetic component, the assembly achieves a superior preservation effect. The shell features snap-fit ​​fasteners at its edges, and locking holes are formed in the grid on the outer wall of the container. The snap-fit ​​fasteners and locking holes secure the shell to the reinforcing rib layer on the outer wall of the container. The magnetic component is positioned within a cavity formed between the shell and the reinforcing rib layer, bringing it closer to the container and the food inside. The magnetic field generated by the magnetic component acts on the food within the container, resulting in better preservation. The shell's fastening to the reinforcing rib layer on the outer wall of the container facilitates easy disassembly and maintenance. The magnetic generating assembly, consisting of a magnetic component and a shell, requires fewer components, resulting in lower cost and simpler assembly. Since only locking holes are needed in the grid on the outer wall of the container, it requires minimal modification to the existing container structure, enhancing its practicality.

[0010] In one exemplary embodiment of this disclosure, the housing includes a cover plate and a side panel, the side panel extending along the edge contour of the cover plate to form a recess with one open end, the magnetic element being accommodated in the recess; a buckle protruding from one end of the side panel away from the cover plate, the end of the side panel away from the cover plate abutting against the reinforcing rib layer, the buckle engaging with the buckle hole.

[0017] The above-mentioned technical features have at least the following technical effects:

[0018] In this application, by setting a connector to connect the center of the cover plate and the container body, the center of the cover plate is constrained, which can prevent the center of the shell from tilting up and further causing the magnetic components to shake.

[0019] In one exemplary embodiment of this disclosure, the bottom wall of the container body is provided with the reinforcing rib layer, and the magnetic generating component is disposed on the bottom side of the container body;

[0020] Multiple support legs are also spaced apart on the bottom wall of the container body. The container body is supported in the refrigeration chamber by the support legs, and the cover plate is not lower than the bottom surface of the support legs in the vertical direction.

[0021] The above-mentioned technical features have at least the following technical effects:

[0022] In this application, by placing the magnetic component on the bottom side of the container body and ensuring it is not lower than the bottom surface of the support legs in the vertical direction, the magnetic generating component is prevented from being exposed. The container body naturally shields the magnetic generating component, avoiding the shell of the magnetic generating component from supporting the bottom and causing improper installation of the container body. Simultaneously, the magnetic generating component is close to the containing cavity, allowing for closer contact with the food inside and resulting in better magnetic field preservation.

[0023] In one exemplary embodiment of this disclosure, the cover plate has a protruding positioning boss on the side facing the container body, and the magnetic component has a positioning hole that matches the contour of the positioning boss, and the positioning boss is engaged in the positioning hole.

[0024] The above-mentioned technical features have at least the following technical effects:

[0025] In this application, by setting positioning bosses and positioning holes, the magnetic component and the cover plate are positioned, which enables the magnetic component to be installed in the preset position, prevents it from deviating, and improves assembly efficiency and quality.

[0026] In one exemplary embodiment of this disclosure, the magnetic component is a sheet-like structure, which is laid flat on the side of the cover plate facing the container body. An adhesive layer is provided between the magnetic component and the cover plate, and the magnetic component is glued and fixed to the cover plate through the adhesive layer.

[0027] The above-mentioned technical features have at least the following technical effects:

[0028] In this application, by laying the magnetic component flat on the cover plate, the magnetic component can cover the container body as much as possible, and the magnetic field it generates can cover all positions within the accommodating cavity as much as possible. The magnetic component is fixed to the cover plate by an adhesive layer, thereby improving the connection stability between the magnetic component and the cover plate, while avoiding damage to the structure of the magnetic component and the cover plate.

[0029] In one exemplary embodiment of this disclosure, the plurality of legs are rectangularly distributed on the bottom wall of the container body, and the cover plate is disposed between the plurality of legs. The edge of the cover plate is provided with a limiting groove that matches the outline shape of the legs.

[0030] The above-mentioned technical features have at least the following technical effects:

[0031] In this application, by distributing multiple legs in a rectangular pattern, the supporting stability of the container body can be improved. Positioning the cover between the multiple legs and using a limiting groove to engage with the legs for positioning guides the installation of the shell onto the reinforcing rib layer, improving assembly efficiency.

[0032] In one exemplary embodiment of this disclosure, multiple magnetic generating components are provided, and each of the multiple magnetic generating components corresponds to one of the multiple grids. The magnetic element is snapped into the grid, and the housing is fastened to the top of the grid.

[0033] The above-mentioned technical features have at least the following technical effects:

[0034] In this application, by setting multiple magnetic generating components and distributing them in different positions, the magnetic field distribution in each area of ​​the accommodating cavity is uniform, and the food in the accommodating cavity can be subjected to the magnetic field without dead angles, thereby improving the magnetic field preservation effect.

[0035] In one exemplary embodiment of this disclosure, the grid has an annular protrusion, and there is a gap between the outer sidewall of the annular protrusion and the inner sidewall of the grid. An installation groove for clamping the magnetic component is formed in the annular protrusion, and a notch communicating with the installation groove is provided on the annular protrusion. The notch is used for external force to remove the magnetic component from the installation groove.

[0036] The above-mentioned technical features have at least the following technical effects:

[0037] In this application, by setting an annular protrusion to form an installation groove, which matches the size of the magnetic component, the magnetic component can be clamped tightly. At the same time, by setting a notch, the magnetic component can be removed through the notch, which facilitates subsequent maintenance and replacement.

[0038] Beneficial effects:

[0039] In this application, a magnetic generating assembly is constructed, comprising a shell and a magnetic component. The shell has snap-fit ​​fasteners at its edges, and locking holes are formed in the grid on the outer wall of the container body. The snap-fit ​​fasteners and locking holes engage with the reinforcing rib layer on the outer wall of the container body. The magnetic component is positioned within a cavity formed between the shell and the reinforcing rib layer, bringing it closer to the container cavity and the food inside. The magnetic field generated by the magnetic component acts on the food within the cavity, resulting in better preservation. Because the shell is fastened to the reinforcing rib layer on the outer wall of the container body, the magnetic generating assembly is easier to disassemble, facilitating future maintenance and replacement. The magnetic generating assembly consists of a magnetic component and a shell, requiring fewer components, resulting in low cost and simple assembly. Since only locking holes are needed in the grid on the outer wall of the container body, minimal changes are made to the original container structure, enhancing its practicality.

Detailed Implementation

[0056] 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.

[0057] 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.

[0058] 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.

[0059] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, 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.

[0060] Magnetic field preservation, an emerging technology in the refrigerator field, works by using magnetic components to create a magnetic field within the container's cavity. This places chilled meat and other foods in a magnetic environment, influencing the physical properties and movement of water molecules in the food and inhibiting microbial activity, thereby improving the food's preservation effect. However, in related technologies, the magnetic components are typically located within the inner liner's bubble layer, making them inconvenient for later removal and maintenance. Their fixing structure is complex, costly, and located far from the food, resulting in poor magnetic field preservation performance. To address this problem, this application proposes a refrigerator.

[0061] For ease of understanding, the side of the refrigerator facing the user is the front direction, and the side facing away from the user is the back direction.

[0062] See Figures 1 to 8 A refrigerator may include a cabinet. The cabinet is the outer shell of the refrigerator and is hollow inside to accommodate other components of the refrigerator. The cross-section of the cabinet may be rectangular or other shapes.

[0063] In some embodiments, the refrigerator may include an inner liner disposed within the refrigerator body, forming a cooling compartment with a front opening. The cooling compartment is used to store items to be preserved. Depending on the required temperature for preserving the items, the inner liner may include a freezer inner liner and a refrigerator inner liner. The cooling compartment formed by the freezer inner liner is the freezer compartment, and the cooling compartment formed by the refrigerator inner liner is the refrigerator compartment. The temperature in the freezer compartment can be controlled below zero for preserving meats and other items that require long-term storage, while the temperature in the refrigerator compartment can be controlled above zero for everyday vegetables and cooked meals.

[0064] In some embodiments, the freezer liner and the refrigerator liner are arranged alternately, such as by alternating vertically or horizontally, to form different types of refrigerators.

[0065] In some embodiments, the refrigerator may include a door. The door is rotatably connected to the refrigerator body, specifically rotatably connected to the front side of the body, for opening and closing the cooling compartment. When the door is open, it facilitates the user to store and retrieve items in the cooling compartment, while when the door is closed, the cooling compartment is sealed, thereby preserving the items inside at a low temperature.

[0066] In some embodiments, the refrigerator may include shelves. The shelves are horizontally positioned within the refrigeration compartment to support items. Multiple shelves may be provided, dividing the refrigeration compartment vertically into several independent areas for storing different items, thus improving the space utilization of the refrigeration compartment.

[0067] In some embodiments, the refrigerator may include a container 1. The container 1 is disposed in the refrigeration compartment, and a vacuum environment can be formed inside the container 1 to improve the food preservation effect. Specifically, the container 1 may include a container body 10 disposed in the refrigeration compartment, the container body 10 forming a receiving cavity with a front opening, and the container body 10 may be placed on one of the partitions in the refrigeration compartment or on the bottom surface of the refrigeration compartment. The container body 10 is the main structure of the container 1, and the cross-section of the container body 10 may be rectangular, so that the receiving cavity contains a rectangular cavity.

[0068] In some embodiments, the container 1 may further include a drawer 11. The drawer 11 is pull-out disposed in the accommodating cavity and can open and close the front opening of the accommodating cavity. When the front opening of the accommodating cavity is closed by the drawer 11, a sealed space is formed in the accommodating cavity to store items. When the drawer 11 is pulled forward, the front opening of the accommodating cavity is open, making it convenient for the user to place and retrieve the stored items through the drawer 11.

[0069] In some embodiments, a reinforcing rib layer 12 may be provided on the outer side wall of the container body 10. The reinforcing rib layer 12 includes multiple horizontal ribs 121 and vertical ribs 122, the horizontal ribs 121 and vertical ribs 122 extending in the same direction, and the multiple horizontal ribs 121 and multiple vertical ribs 122 are arranged intersectingly to form a mesh structure with multiple grids 123. The mesh structure protrudes from the outer side wall of the container body 10, thereby strengthening the structural strength of the container body 10 through the formed mesh structure and preventing deformation of the outer side wall of the container body 10 after vacuuming.

[0070] In some embodiments, the horizontal ribs 121 may extend along the width direction of the container body 10, while the vertical ribs 122 may extend along the length direction of the container body 10, so that the grid 123 formed by the two is square. The plurality of horizontal ribs 121 and the plurality of vertical ribs 122 may be arranged at equal intervals, so that the resulting plurality of grids 123 have the same structure.

[0071] In some embodiments, reinforcing ribs 12 may be provided on both the bottom and top walls of the container body 10.

[0072] In some embodiments, a reinforcing ring rib layer 14 may be provided on the peripheral sidewall of the container body 10. The reinforcing ring rib layer 14 is arranged around the peripheral sidewall of the container body 10 and connected to the reinforcing rib layer 12. The reinforcing ring rib layer 14 includes multiple first ring ribs 141 and second ring ribs 142, which are arranged intersectingly to form a mesh-like reinforcing ring rib layer 14. Specifically, the first ring ribs 141 are spaced apart on the peripheral sidewall along the height direction of the container body 10, and the second ring ribs 142 are spaced apart on the peripheral sidewall along a direction perpendicular to the first ring ribs 141. The second ring ribs 142 are connected to the horizontal ribs 121 or the vertical ribs 122.

[0073] In some embodiments, the peripheral sidewalls of the container body 10 include sidewalls excluding its front opening. Each sidewall is provided with a reinforcing ring rib layer 14, and they are interconnected to form a whole. The reinforcing ring rib layer 14 is connected to the reinforcing rib layers 12 located on the bottom wall and the top wall to form a whole.

[0074] In some embodiments, when the accommodating cavity is closed by the drawer 11 to form a sealed space, a vacuum environment can be created inside the accommodating cavity by setting a vacuum pump to improve the food preservation effect.

[0075] It should be noted that food spoilage is mainly caused by the life activities of microorganisms. The basic life processes of microorganisms are nutrition and respiration. In a vacuum environment, the growth and reproduction of aerobic microorganisms are inhibited, which can delay the spoilage of food placed in the container and achieve the effect of food preservation.

[0076] In some embodiments, the container body 10 is provided with an air extraction hole that communicates with the interior of the accommodating cavity. A vacuum pump is located outside the container body 10 and is connected to the air extraction hole to extract air from the accommodating cavity and maintain a vacuum environment.

[0077] In some embodiments, to further improve the preservation effect within container 1, the refrigerator may also include a magnetic generating component 2. The magnetic generating component 2 is disposed outside the container body 10 and is used to generate a magnetic field within the accommodating cavity. This magnetic field can inhibit microbial activity, reduce enzyme activity, and decrease food moisture loss. The magnetic field alters the distribution of calcium ions across the microbial cell membrane, causing changes in cell membrane potential, thereby altering its permeability and reducing the survival rate of microorganisms. The structure of water molecule clusters is disrupted in the magnetic field; larger associated water molecule clusters become smaller, or even single water molecules. These water molecules are more likely to adhere to the food surface and pores, and may even be absorbed, thus reducing food moisture loss. The magnetic field alters the catalytic activity of enzymes by affecting their conformation. Some enzymes contain small amounts of transition metal atoms such as iron, cobalt, and manganese as active centers; an external magnetic field can affect these active centers, thereby reducing the activity of these enzymes.

[0078] In some embodiments, the magnetic generating assembly 2 may include a magnetic element 21. The magnetic element 21 is disposed on the reinforcing rib layer 12 and configured to create a magnetic field within the accommodating cavity to improve the preservation effect of food within the cavity. The magnetic element 21 may be disposed on the reinforcing rib layer 12 located on the bottom wall of the container body 10, or on the reinforcing rib layer 12 located on the top wall of the container 1. This embodiment does not impose any limitations, as long as the magnetic element 21, disposed on the reinforcing rib layer 12, can generate a magnetic field within the accommodating cavity.

[0079] In some embodiments, the magnetic generating assembly 2 may further include a housing 20, which is used to mount the magnetic component 21 onto the reinforcing rib layer 12, preventing it from being exposed. The detachable connection between the housing 20 and the reinforcing rib layer 12 facilitates the disassembly and assembly of the magnetic component 21 during later maintenance and upkeep.

[0080] In some embodiments, when the housing 20 is connected to the reinforcing rib layer 12, they can be connected by a snap-fit ​​structure 203, allowing the housing 20 and the reinforcing rib layer 12 to be detachably connected. Specifically, at least a portion of the sidewalls of the mesh 123 are provided with snap holes 124, and the edge of the housing 20 is provided with snap-fits 203 that can be inserted into the snap holes 124, so that the housing 20 is fastened to the reinforcing rib layer 12. The housing 20 and the reinforcing rib layer 12 enclose a mounting cavity, in which the magnetic component 21 is housed and protected by the housing 20. Connecting the reinforcing rib layer 12 and the housing 20 by snap-fits 203 facilitates the detachable connection of the housing 20, thereby facilitating the maintenance and repair of the magnetic component 21.

[0081] In some embodiments, the housing 20 may include a cover plate 201 and a side panel 202. The side panel 202 extends along the edge contour of the cover plate 201 to form a recessed cavity with one open end, the open end of which may face the reinforcing rib layer 12. The magnetic element 21 is accommodated in the recessed cavity for mounting and fixing the magnetic element 21. A snap fastener 203 protrudes from one end of the side panel 202 away from the cover plate 201, and the end of the side panel 202 away from the cover plate 201 abuts against the reinforcing rib layer 12. The snap fastener 203 engages with the snap hole 124 on the side wall of the mesh 123. When the housing 20 is installed on the reinforcing rib layer 12, the recessed cavity forms part of the mounting cavity. The snap fastener 203 engages with the corresponding snap hole 124 to connect the housing 20 and the reinforcing rib layer 12. When it is necessary to remove the housing 20, the snap fastener 203 is disengaged from the snap hole 124 to separate the two. It should be noted that when the magnetic component 21 is placed in the cavity, one side of it can be in contact with the cover plate 201, and the other side can abut against the reinforcing rib layer 12, thereby clamping the magnetic component 21 and preventing it from shaking.

[0082] In some embodiments, since the mesh 123 is formed by the intersection of horizontal ribs 121 and vertical ribs 122, the slot 124 can be formed on the horizontal ribs 121 or on the vertical ribs 122.

[0083] In some embodiments, the cover plate 201 can be a flat plate structure, and its cross-section can be rectangular, circular, or polygonal. In this embodiment, the cover plate 201 has a rectangular cross-section, corresponding to the shape of the top or bottom wall of the container body 10.

[0084] In some embodiments, the side panel 202 may include a first side plate 204 and a second side plate 205 disposed opposite to each other, and the first side plate 204 and the second side plate 205 are correspondingly connected to the two opposite edges of the cover plate 201. The first side plate 204 and the second side plate 205 are both parallel to the horizontal rib 121 or the vertical rib 122. A plurality of buckles 203 are provided at intervals along the length direction of the end of the first side plate 204 and the second side plate 205 away from the cover plate 201. A plurality of locking holes 124 are provided on the two opposite horizontal ribs 121 or the two opposite vertical ribs 122. The plurality of buckles 203 are engaged in the plurality of locking holes 124 one by one. By setting the first side plate 204 and the second side plate 205, a plurality of buckles 203 can be disposed opposite to each other. The housing 20 can be engaged with the reinforcing rib layer 12 by the plurality of buckles 203 on both sides, thereby improving the connection stability between the housing 20 and the reinforcing rib layer 12.

[0085] In some embodiments, wall reinforcing ribs 209 connected to the cover plate 201 may be provided on the inner surfaces of the first side plate 204 and the second side plate 205. By providing wall reinforcing ribs 209, the structural strength of the first side plate 204 and the second side plate 205 is improved, preventing them from bending easily. Multiple wall reinforcing ribs 209 may be provided, and the multiple wall reinforcing ribs 209 correspond one-to-one with the positions of multiple buckles 203.

[0086] In some embodiments, snap-fit ​​reinforcing ribs 208 connected to snap-fit ​​203 may be provided on the outer surfaces of the first side plate 204 and the second side plate 205. By providing snap-fit ​​reinforcing ribs 208, the structural strength of snap-fit ​​203 is improved, preventing it from breaking easily. Multiple snap-fit ​​reinforcing ribs 208 may be provided, and multiple snap-fit ​​reinforcing ribs 208 are connected one-to-one with multiple snap-fit ​​203s.

[0087] In some embodiments, the side panel 202 may also include a third side plate and a fourth side plate disposed opposite to each other. The first side plate 204, the third side plate, the second side plate 205 and the fourth side plate are connected in sequence to form the side panel 202. Multiple buckles 203 may also be provided on the third side plate and the fourth side plate, so that the four edges of the housing 20 are fastened to the mesh structure by the buckles 203.

[0088] In some embodiments, the buckle 203 may have a certain elasticity so that it can be fastened in the buckle hole 124 and be secured in the buckle hole 124 by its own elastic deformation.

[0089] In some embodiments, the bottom wall of the container body 10 is provided with the aforementioned reinforcing rib layer 12, and the magnetic generating component 2 is disposed on the bottom side of the container body 10, thereby preventing the magnetic generating component 2 from being exposed to the outside. The container body 10 naturally shields the magnetic generating component 2. At the same time, the magnetic generating component 2 is close to the accommodating cavity, which allows it to be closer to the food in the accommodating cavity, resulting in a better magnetic field preservation effect.

[0090] In some embodiments, multiple support legs 13 may be spaced apart on the bottom wall of the container body 10. The container body 10 is supported in the refrigeration chamber by the support legs 13, and the cover plate 201 is not lower than the bottom surface of the support legs 13 in the vertical direction, which can prevent the housing 20 in the magnetic generator assembly 2 from being supported by the bottom, thus preventing the container body 10 from being improperly installed. Preferably, the cover plate 201 is higher than the bottom surface of the support legs 13 in the vertical direction, and the container body 10 contacts the refrigeration chamber through the support legs 13. Three, four or more support legs 13 can be provided, as long as they can stably support the container body 10.

[0091] In some embodiments, multiple support legs 13 are arranged in a rectangular pattern on the bottom wall of the container body 10 to improve the support stability of the container body 10. In this embodiment, four support legs 13 are provided, arranged in a rectangular pattern at the four corners of the bottom wall of the container body 10.

[0092] In some embodiments, when the support leg 13 is disposed on the container body 10, it is separated from the horizontal rib 121 and the vertical rib 122 and does not interfere with each other. The support leg 13 may also be disposed within the grid 123 and extend out of the grid 123. The support leg 13 may be a rectangular column structure or a cylindrical structure, etc.

[0093] In some embodiments, a cover plate 201 is disposed between a plurality of legs 13. The edge of the cover plate 201 is provided with a limiting groove 207 that is adapted to the contour shape of the legs 13. The portion of the legs 13 facing the cover plate 201 abuts against the limiting groove 207 to limit the cover plate 201. When the housing 20 is installed, by making the cover plate 201 abut against the legs 13, the legs 13 are engaged in the limiting groove 207, so that the cover plate 201 can move along the legs 13 to a preset installation position.

[0094] In some embodiments, when the support leg 13 is a rectangular column structure, the corners of the support leg 13 can be rounded or vertically transitioned, and the shape of the limiting groove 207 matches accordingly, such as being a corresponding arc-shaped groove structure or a rectangular groove structure. When the support leg 13 is a cylindrical structure, the limiting groove 207 is a matching arc-shaped groove structure.

[0095] In this embodiment, the support leg 13 is disposed between adjacent second ring ribs 142, and there is a gap between the support leg 13 and the second ring rib 142. The edge of the cover plate 201 is provided with a limiting protrusion that fits into the gap. The limiting protrusion cooperates with the limiting groove 207 to assist in the positioning and installation of the cover plate 201 and the support leg 13.

[0096] In some embodiments, the magnetic element 21 may be a permanent magnet capable of generating a magnetic field within the accommodating cavity. Alternatively, the magnetic element 21 may be other electromagnetic devices, such as a Helmholtz coil, which generates a magnetic field when energized. This coil is disposed within the mounting cavity and can be connected to an external power source via wires or powered by an internal battery.

[0097] In some embodiments, the side of the cover plate 201 facing the container body 10 may have a protruding positioning boss 206, and the magnetic component 21 has a positioning hole 211 that matches the contour of the positioning boss 206. The positioning boss 206 is engaged in the positioning hole 211, so that when installing the magnetic component 21, it can be aligned and installed on the cover plate 201, improving installation accuracy and ease of operation. The positioning boss 206 may be in the shape of a platform, and the positioning hole 211 may be a corresponding platform hole. The positioning boss 206 may also be in other shapes, such as triangles, circles, etc., and the shape of the positioning hole 211 may correspond to the shape of the platform.

[0098] In some embodiments, multiple positioning bosses 206 can be spaced apart along the length of the cover plate 201, for example, two, three or four can be spaced apart, and multiple positioning holes 211 can be opened at corresponding intervals, so that the magnetic component 21 is positioned relative to the cover plate 201 by the multiple positioning bosses 206 being engaged one by one with the multiple positioning holes 211, thereby improving the installation accuracy of the magnetic component 21.

[0099] In some embodiments, the magnetic element 21 can be a sheet structure, which is laid flat on the side of the cover plate 201 facing the container body 10, so that it can cover the container body 10 as much as possible, and the magnetic field it forms can cover all positions in the accommodating cavity as much as possible.

[0100] In some embodiments, the positioning hole 211 and the positioning boss 206 on the magnetic component 21 are fitted with a clearance, so that there is a certain fitting clearance between the two. The fitting clearance can be between 2mm and 3mm, preferably 2.5mm, to avoid the positioning boss 206 being difficult to align with the positioning hole 211 due to the fitting clearance being too small, which would cause the magnetic component 21 to lift up.

[0101] In some embodiments, an adhesive layer 212 is provided between the magnetic component 21 and the cover plate 201. The magnetic component 21 is adhered and fixed to the cover plate 201 through the adhesive layer 212, thereby improving the connection stability between the magnetic component 21 and the cover plate 201 and avoiding damage to the structure of the magnetic component 21 and the cover plate 201. The adhesive layer 212 can be adhesive applied to the magnetic component 21 and / or the cover plate 201, used to bond the magnetic component 21 and the cover plate 201. After the adhesive cures, the adhesive layer 212 is formed. Alternatively, the adhesive layer 212 can also be double-sided adhesive tape applied to the magnetic component 21 and / or the cover plate 201. The double-sided adhesive tape is very thin, which can both bond and fix the magnetic component 21 and the cover plate 201 without causing local protrusions in the magnetic component 21.

[0102] In this embodiment, the adhesive layer 212 is double-sided adhesive tape. One side is adhered to the cover plate 201 and spaced apart from the positioning boss 206, so that the other side can be adhered to the magnetic component 21. The thickness of the adhesive layer 212 is between 0.2mm and 0.3mm, preferably 0.25mm. This moderate thickness can prevent air bubbles from forming during application due to uneven surface flatness of the magnetic component 21, and also prevent the magnetic component 21 from exceeding the depth of the cavity, thus affecting the installation between the shell 20 and the container body 10.

[0103] In some embodiments, the edge of the magnetic component 21 and the inner wall of the side circumference 202 are fitted with a gap, so that there is a certain fitting gap between the two. The fitting gap can be between 1mm and 2mm, preferably 1.5mm, which is smaller than the fitting gap between the positioning hole 211 and the positioning boss 206. This can prevent the inside of the magnetic component 21 from going beyond the positioning boss 206 and sticking crookedly onto the positioning boss 206.

[0104] In some embodiments, the magnetic generating assembly 2 may further include a connector 22. The connector 22 is detachably connected between the center of the cover plate 201 and the container body 10, thereby ensuring that the center of the cover plate 201 is connected to the container body 10 under force, preventing the center of the cover plate 201 from tilting up. The connector 22 may be an adhesive, applied to the center of the side of the cover plate 201 facing the container body 10, to adhere and fix it to the surface of the reinforcing rib layer 12 on the container body 10.

[0105] In some embodiments, the connector 22 can also be a fixing screw. Correspondingly, screw holes are provided at the center of the cover plate 201 and on the corresponding reinforcing rib layer 12. The cover plate 201 is screwed onto the screw holes by fixing screws, so that the center of the cover plate 201 and the reinforcing rib layer 12 are detachably connected. The screw holes on the reinforcing rib layer 12 can be provided on the horizontal rib 121 or the vertical rib 122, or at the intersection of the horizontal rib 121 and the vertical rib 122. Alternatively, a connecting part can be provided on the outer wall of the container body 10, with the connecting part located within one of the grids 123, and the screw holes are provided on the connecting part.

[0106] In some embodiments, the screw hole at the center of the cover plate 201 corresponds to the position of one of the positioning bosses 206, so that the fixing screw can avoid the magnetic component 21 and avoid damage to the magnetic component 21.

[0107] See Figures 9 to 14 In other embodiments, multiple magnetic generating components 2 can be provided, each corresponding to a different grid 123. Magnetic elements 21 are secured within the grid 123, and the housing 20 is fastened to the top of the grid 123, thereby forming the aforementioned mounting cavity by enclosing the inner wall of the grid 123 and the outer wall of the container body 10. This prevents the magnetic elements 21 from being exposed and also prevents them from accidentally detaching from the grid 123. By providing multiple magnetic generating components 2 distributed in different positions, the magnetic field distribution within the cavity is uniform, ensuring that the food within the cavity receives a magnetic field without any blind spots, thus improving the magnetic field preservation effect.

[0108] In some embodiments, three, four, five or more magnetic generating components 2 may be provided and distributed in different grids 123.

[0109] In some embodiments, four magnetic generating components 2 are arranged in a rectangular pattern on the outer wall of the container body 10, which enables the generated magnetic field to reach the corners and center of the accommodating cavity, thereby improving the magnetic field preservation effect.

[0110] In some embodiments, an annular protrusion 125 may be provided within the grid 123, with a gap between the outer wall of the annular protrusion 125 and the inner wall of the grid 123. A mounting groove for clamping the magnetic component 21 is formed within the annular protrusion 125. A notch 126 communicating with the mounting groove may be provided on the annular protrusion 125, allowing external force to remove the magnetic component 21 from the mounting groove. By providing the mounting groove formed by the annular protrusion 125, the magnetic component 21 can be securely clamped, and by providing the notch 126, the magnetic component 21 can be removed through the notch 126, facilitating subsequent maintenance and replacement.

[0111] In some embodiments, the size of the notch 126 can be set according to the actual situation, for example, the notch 126 corresponds to one-quarter, one-half or one-third of the annular protrusion 125.

[0112] In some embodiments, a limiting part 200 may be provided on the side of the housing 20 facing the container body 10. The limiting part 200 extends toward the outer side wall of the container body 10 and abuts against the magnetic element 21 after the housing 20 is fastened onto the mesh 123, so as to further fix the magnetic element 21 and prevent the magnetic element 21 from coming off.

[0113] In summary, this application utilizes a magnetic generating component 2, comprising a housing 20 and a magnetic element 21. The housing 20 has snap fasteners 203 on its edge, and slots 124 are formed in the grid 123 on the outer wall of the container body 10. The snap fasteners 203 and slots 124 engage with the reinforcing rib layer 12 on the outer wall of the container body 10, allowing the housing 20 to be fastened to it. The magnetic element 21 is positioned within the mounting cavity formed between the housing and the reinforcing rib layer 12, bringing it closer to the container cavity and the food inside. The magnetic field generated by the magnetic element 21 acts on the food within the container cavity, resulting in better preservation. Because the housing 20 is fastened to the reinforcing rib layer on the outer wall of the container body 10, the magnetic generating component 2 is easier to disassemble, facilitating future maintenance and replacement. The magnetic generating component 2 consists of the magnetic element 21 and the housing 20, requiring fewer components, resulting in lower cost and simpler assembly. Since only holes 124 need to be opened on the grid 123 formed on the outer side wall of the container body 10, the original container structure is modified little, making it more practical.
