Description

Technical Field

[0001] This utility model relates to the field of home appliances, specifically to a food preservation device and a refrigeration equipment. Background Technology

[0002] In the field of food preservation and storage, magnetic field control technology is a key means of delaying the oxidation and deterioration of food, and its application directly affects the preservation effect and user experience. Traditional technical solutions mostly focus on the physical form and adjustment mechanism of magnetic field generation: on the one hand, permanent magnets are embedded in the food preservation device at fixed intervals to form a static magnetic field. Although this can achieve basic preservation functions, it ignores the different requirements of different foods for magnetic field strength. For example, delicate leafy green vegetables need a weak magnetic field to avoid cell damage, while deep-sea fish need a strong magnetic field to inhibit enzymatic reactions. On the other hand, some devices introduce manual adjustment mechanisms, allowing users to change the magnetic field coverage by pushing and pulling the magnet components through slide rails. However, this coarse-grained adjustment not only relies on user experience and judgment, but also cannot sense changes in magnetic field parameters in real time to form dynamic feedback.

[0003] In recent years, although electromagnet control schemes have achieved stepless changes in magnetic field strength through current adjustment, their inherent drawbacks are equally significant: high-frequency current regulation leads to increased energy consumption, complex circuit layouts increase equipment failure rates, and electromagnetic radiation may interfere with the normal operation of surrounding smart home appliances. Furthermore, existing technologies generally lack intelligent adjustment capabilities, making it difficult to integrate into smart home ecosystems. This necessitates long-term manual intervention from users, as they cannot automatically optimize magnetic field parameters based on food storage cycles or changes in environmental temperature and humidity. Summary of the Invention

[0004] One of the objectives of this invention is to provide a food preservation device to solve the technical problem in the prior art where the actual magnetic field strength inside the food preservation device does not match the target magnetic field strength of the food, resulting in poor food preservation effect.

[0005] To achieve one of the aforementioned objectives, this utility model provides a food preservation device, comprising: a storage unit for placing food; a first component located in a first direction of the storage unit for generating a first magnetic field covering the storage unit, the first magnetic field being used to preserve the food; and a transmission component connected to the storage unit or the first component for changing the relative position between the first component and the storage unit in the first direction; in a first state, the first component and the storage unit have a first distance; and in a second state, the first component and the storage unit have a second distance different from the first distance.

[0008] As a further improvement of one embodiment of the present invention, the first connecting member is fixed to the first component, the second connecting member includes a gear, and the guide includes a rack extending along its length direction. In a first state, the gear meshes with a first position of the rack, and in a second state, the gear meshes with a second position on the rack that is different from the first position.

[0009] As a further improvement of one embodiment of the present invention, the second connecting member includes a motor, the motor including an output shaft connected to the gear, and when changing from the first state to the second state, the gear rotates around the output shaft.

[0029] like Figure 1 As shown, one embodiment of this utility model provides a food preservation device 100.

[0030] Food preservation device 100 refers to equipment or containers specifically designed for storing, preserving, and managing food. These devices ensure that food retains its freshness, nutritional value, and taste during storage. Food preservation device 100 can be a refrigerator, freezer, or a module within a refrigerator or freezer, such as a crisper drawer.

[0031] The food preservation device 100 includes a storage unit 11 for placing food. The storage unit 11 can be in the form of a planar structure or a cavity structure, such as a tabletop or a flat plate, or a cavity with an opening or a drawer-type cavity. This invention does not impose any specific limitations on this.

[0032] The food preservation device 100 includes a first component 12, which is located in a first direction of the storage unit 11 and is used to generate a first magnetic field covering the storage unit 11.

[0033] On the one hand, the first magnetic field is used to preserve the food inside the food preservation device 100.

[0034] Specifically, the preservation effect of magnetic fields on food lies primarily in their ability to inhibit the growth of microorganisms and molds, thereby extending the storage period. Specifically, when using magnetic fields to assist in food storage, the magnetic field restricts the free path of water molecules to a certain extent. This manifests as the breaking of hydrogen bonds within water molecules, inhibiting crystal nucleus growth during the phase transition. The growth rate of ice crystals exceeds the migration rate of water molecules, resulting in smaller ice crystals that cause less damage to cells. This reduces the loss of juices from the food, better preserving its nutrition and flavor. Therefore, magnetic fields can be used to assist in food storage, thereby extending the storage period.

[0035] On the other hand, by adjusting the distance between the first component 12 and the storage unit 11, the actual magnetic field strength inside the food preservation device 100 is indirectly affected or adjusted so that it matches the target magnetic field strength of the food. In this way, adaptive adjustment can be made according to the target magnetic field strength corresponding to different types of food.

[0036] In one specific embodiment, the target magnetic field strength includes at least one of a minimum target magnetic field strength and a maximum target magnetic field strength.

[0037] In this embodiment, when the actual magnetic field strength at the storage unit 11 is within the range of the minimum target magnetic field strength and the maximum target magnetic field strength, the food in the storage unit 11 can achieve a better preservation effect. Of course, when the type of food in the storage unit 11 changes, the corresponding target magnetic field strength will also change accordingly.

[0038] In one specific embodiment, a magnetic field strength sensor is provided at the storage unit 11 to detect the actual magnetic field strength at the storage unit 11 in real time.

[0039] The first direction refers to the positional direction of the first component 12 relative to the storage unit 11, and the direction of movement of the first component 12 or the storage unit 11.

[0040] In one specific embodiment, the first direction is the vertical direction, that is, the first component 12 moves in the up and down direction relative to the placement unit 11.

[0041] In one specific embodiment, the first direction is the horizontal direction, that is, the first component 12 moves in the left and right direction relative to the placement unit 11.

[0042] The food preservation device 100 includes a transmission component 13, which is connected to the storage unit 11 or the first component 12 and is used to change the relative position between the first component 12 and the storage unit 11 in a first direction.

[0043] In the first state, there is a first distance between the first component 12 and the storage unit 11.

[0044] In the second state, the first component 12 and the storage unit 11 have a second distance that is different from the first distance.

[0045] It should be noted that, on the one hand, the first state refers to the positional state of the storage unit 11 and the first component 12 when the actual magnetic field strength of the first magnetic field at the storage unit 11 is less than the minimum target magnetic field strength (i.e., the actual magnetic field strength does not match the target magnetic field strength).

[0046] On the other hand, the first state refers to the positional state of the storage unit 11 and the first component 12 after adjusting the relative position between the storage unit 11 and the first component 12, such that the actual magnetic field strength of the first magnetic field at the storage unit 11 is greater than or equal to the minimum target magnetic field strength (i.e., the actual magnetic field strength matches the target magnetic field strength).

[0047] In the first state, when the actual magnetic field strength of the first magnetic field at the storage unit 11 is less than the minimum target magnetic field strength, the transmission component 13 is used to move the first component 12 along the first direction toward the storage unit 11; or, the transmission component 13 is used to move the storage unit 11 along the first direction toward the first component 12; so that the distance between the storage unit 11 and the first component 12 is shortened, and the actual magnetic field strength at the storage unit 11 is increased, until the actual magnetic field strength of the first magnetic field is greater than or equal to the minimum target magnetic field strength.

[0048] Similarly, on the one hand, the second state refers to the positional state of the storage unit 11 and the first component 12 when the actual magnetic field strength of the first magnetic field at the storage unit 11 is greater than the maximum target magnetic field strength (i.e., the actual magnetic field strength does not match the target magnetic field strength).

[0049] On the other hand, the second state refers to the positional state of the storage unit 11 and the first component 12 after adjusting the relative position between the storage unit 11 and the first component 12, such that the actual magnetic field strength of the first magnetic field at the storage unit 11 is less than or equal to the maximum target magnetic field strength (i.e., the actual magnetic field strength matches the target magnetic field strength).

[0050] In the second state, when the actual magnetic field strength of the first magnetic field at the storage unit 11 is greater than the maximum target magnetic field strength, the transmission component 13 is used to move the first component 12 away from the storage unit 11 along the first direction; or, the transmission component 13 is used to move the storage unit 11 away from the first component 12 along the first direction; thereby increasing the distance between the storage unit 11 and the first component 12, and decreasing the actual magnetic field strength at the storage unit 11, until the actual magnetic field strength of the first magnetic field is less than or equal to the maximum target magnetic field strength.

[0051] In one specific embodiment, when the storage unit 11 is in the second state, the actual magnetic field strength of the first magnetic field at the storage unit 11 is less than the minimum target magnetic field strength corresponding to the current food ingredient.

[0052] In this embodiment, the transmission component 13 drives the first component 12 to move closer to the placement unit 11 until the actual magnetic field strength of the first magnetic field is greater than the minimum target magnetic field strength, at which point the movement stops.

[0053] Of course, the storage unit 11 can also be moved closer to the first component 12 by the transmission component 13 until the actual magnetic field strength of the first magnetic field is greater than the minimum target magnetic field strength, at which point the movement stops. Alternatively, the storage unit 11 and the first component 12 can be moved relative to each other simultaneously by the transmission component 13, shortening the distance between them until the actual magnetic field strength of the first magnetic field is greater than the minimum target magnetic field strength, at which point the movement stops. This utility model does not impose specific limitations on these methods.

[0054] In one specific embodiment, when the storage unit 11 is in the second state, the actual magnetic field strength of the first magnetic field at the storage unit 11 is greater than the maximum target magnetic field strength corresponding to the current food ingredient.

[0055] In this embodiment, the transmission component 13 drives the first component 12 to move away from the placement unit 11 until the actual magnetic field strength of the first magnetic field is less than the maximum target magnetic field strength, at which point the movement stops.

[0056] Of course, the storage unit 11 can also be moved away from the first component 12 by the transmission component 13 until the actual magnetic field strength of the first magnetic field is less than the maximum target magnetic field strength, at which point the movement stops. Alternatively, the storage unit 11 and the first component 12 can be moved simultaneously in opposite directions by the transmission component 13, increasing the distance between them until the actual magnetic field strength of the first magnetic field is less than the maximum target magnetic field strength, at which point the movement stops. This invention does not impose specific limitations on these methods.

[0057] like Figure 2As shown, in one embodiment, the transmission assembly 13 includes a first connector 1 connected to the first assembly 12; the transmission assembly 13 includes a second connector 2 connected to the storage unit 11; the transmission assembly 13 includes a guide 3 connected to the first connector 1 and the second connector 2, and the guide 3 extends along the first direction.

[0058] In the first state and the second state, the first connector 1 and the second connector 2 have different distances in a first direction. In other words, in the first state, the distance between the storage unit 11 and the first component 12 is different from the distance between the storage unit 11 and the first component 12 in the second state.

[0059] When the food storage device 100 is placed vertically on the ground, the first direction refers to the vertical direction or the longitudinal axis direction. At this time, the first component 12 is located above the storage unit 11.

[0060] As shown in Figure 3(a), in one specific embodiment, the first connector 1 is columnar, with one end fixed to the first component 12 shown, and the other end fixed to the end of the guide 3 away from the second connector 2; when the food preservation device 100 changes from the first state to the second state, the first connector 1 penetrates the guide groove 15 and is displaced in the first direction.

[0061] Referring to Figure 3(a), in one specific embodiment, the first connector 1 is fixed to the first component 12, the second connector 2 includes a gear 2-1, and the guide 3 includes a rack 3-1 extending along its length. In a first state, the gear 2-1 meshes with the rack 3-1 at a first position; in a second state, the gear 2-1 meshes with the rack 3-1 at a second position different from the first position.

[0062] In other specific embodiments, the first connecting member 1 and the second connecting member 2 may also adopt other connection methods besides gears and racks, such as sliding connection of guide rail and slider, or hinge connection of hinge or rotating shaft, etc. The present invention does not impose specific limitations on this.

[0063] Referring to Figure 3(a), in one specific embodiment, the second connector 2 includes a motor 2-2, which includes an output shaft connected to the gear 2-1. When the food storage device 100 changes from the first state to the second state, the gear 2-1 rotates around the output shaft.

[0064] Continue to refer to Figure 2 As shown, in one embodiment, the food preservation device 100 further includes a housing 14, a storage unit 11 is disposed inside the housing 14, and a guide groove 15 is provided on the housing, the guide groove 15 extending along a first direction.

[0065] In this embodiment, the guide groove 15 can be an independently assembled modular component, assembled with the housing 14 by fasteners; the guide groove 15 can also be an integral design formed directly on the housing 14, with the groove structure formed directly on the housing. This utility model does not impose specific limitations in this regard.

[0066] As shown in Figure 3(b), in one specific embodiment, the guide groove 15 can be a waist-shaped hole, or of course, other shapes, without any specific limitation.

[0067] To prevent the first component 12 or the storage unit 11 from tilting or swaying during movement, and to ensure that the driving force is evenly distributed during the movement of the first component 12 or the storage unit 11, the food preservation device 100 employs two sets of transmission components 13. These two sets of transmission components 13 are respectively located on both sides of the first component 12 or the storage unit 11.

[0068] Based on this, such as Figure 4 As shown, in one embodiment, the transmission component 13 includes a first transmission component 13-1 and a second transmission component 13-2, which are disposed on both sides of the storage unit 11 or the first component 12.

[0069] Specifically, the first transmission assembly 13-1 connects the first sidewall of the storage unit 11 to the first sidewall of the first component 12; the second transmission assembly 13-2 connects the second sidewall of the storage unit 11 to the second sidewall of the first component 12. The first sidewall and the second sidewall of the storage unit 11 are opposite to each other, and the first sidewall and the second sidewall of the first component 12 are opposite to each other.

[0070] In one specific embodiment, the first transmission component 13-1 includes a first connector 1-1, a second connector, and a first guide 3-1; the first connector 1-1 is connected to the first sidewall of the first component 12; the second connector is connected to the first sidewall of the storage unit 11; the first guide 3-1 is connected to the first connector 1-1 and the second connector, and the first guide 3-1 extends along a first direction of the first sidewall.

[0071] The second transmission assembly 13-2 includes a third connector 1-1', a fourth connector, and a second guide 3-1'; the third connector 1-1' connects to the second sidewall of the first assembly 12; the fourth connector connects to the second sidewall of the storage unit 11; the second guide 3-1' connects the third connector 1-1' and the fourth connector, and extends along a first direction of the second sidewall. The first side of the first assembly 12 is positioned opposite to the second side of the first assembly 12.

[0072] In one specific embodiment, the first transmission component 13-1 and the second transmission component 13-2 are symmetrically arranged on both sides of the storage unit 11 or the first component 12.

[0073] In one specific embodiment, the second transmission component 13-2 is connected to the motor 2-2, and under the action of the motor 2-2, it provides power for the movement of the first component 12 or the storage unit 11.

[0074] In this embodiment, the second transmission component 13-2 is a driving component, and the first transmission component 13-1 is an auxiliary component. The auxiliary component moves under the drive of the driving component, providing additional support for the first component 12 or the storage unit 11, achieving synchronous movement. The two work together to ensure that the first component 12 or the storage unit 11 moves smoothly.

[0075] Continue to refer to Figure 4 As shown, in one specific embodiment, the guide groove 15 includes a first guide groove 15-1 and a second guide groove 15-2. The first guide groove 15-1 is disposed on the first side wall of the housing 14 or the storage unit 11 and is used to guide the movement of the first guide member 3. The second guide groove is disposed on the second side wall of the housing 14 or the storage unit 11 and is used to guide the movement of the second guide member 3'. The first guide groove 15-1 and the second guide groove 15-2 are symmetrically arranged.

[0076] like Figure 4 As shown, the following explanation uses two symmetrically distributed sets of transmission components 13 as an example, assuming that each set of transmission components uses a gear and rack connection. The following will combine... Figure 4 The structure shown illustrates the working process of a food preservation device.

[0077] In this example, the first transmission assembly 13-1 includes a first connector 1-1, a first rack 3-1 and a first gear 2-1. The first end of the first connector 1-1 is fixed to the first side wall (e.g., the rear side wall) of the first assembly 12 by a screw, and the second end of the first connector 1-1 is fixed to the end of the first guide 3 away from the second connector.

[0078] The second transmission assembly 13-2 includes a third connector 1-1', a second rack 3-1', and a second gear 2-1'. The first end of the third connector 1-1' is fixed to the first sidewall (e.g., the front sidewall) of the first assembly 12 by a screw. The second end of the second connector 1-1' is fixed to the end of the second guide 3' away from the fourth connector. The second gear 2-1' is connected to the output shaft of the motor 2-2 and rotates around the output shaft.

[0079] Under the action of motor 2-2, the second gear 2-1' is driven to rotate. The rotation of the second gear 2-1' will drive the second rack 3-1' to move along the first direction (vertical direction). The movement of the second rack 3-1' will also drive the first component 12 to move in the first direction.

[0080] Simultaneously, the movement of the first component 12 is transmitted to the first rack 3-1 via the third connector 1-1', and the movement of the first rack 3-1 drives the first gear 2-1 to rotate. The first rack 3-1 is connected to the first component 12 via the first guide 3 and the first connector 1-1, assisting the first component 12 to move along the first direction. The first transmission component 13-1 moves synchronously under the drive of the second transmission component 13-2, ensuring the stability and balance of the first component 12 during movement and preventing the first component 12 from tilting or wobbling during movement.

[0081] By moving the first transmission component 13-1 and the second transmission component 13-2 in the first direction, the distance between the storage unit 11 and the first component 12 can be changed to adjust the actual magnetic field strength at the storage unit 11.

[0082] like Figure 5 As shown, in one embodiment, the food preservation device 100 further includes a second component 16 located in the opposite direction to the first direction of the storage unit 11; the second component 16 is used to generate a second magnetic field covering the storage unit 11. In other words, the storage unit 11 is disposed between the first component 12 and the second component 16.

[0083] In one specific embodiment, the second component 16 can be fixedly disposed inside the housing 14, specifically, fixed to the housing 14 by means of screws, clips, etc.

[0084] In other embodiments, the second component 16 may also be movably connected to the housing 14, which helps to work with the first component 11 to adjust the actual magnetic field strength at the storage unit 11 and improve flexibility.

[0085] In one specific embodiment, the food preservation device 100 further includes a third transmission component connected to the placement unit 11 or the second component 16, used to change the relative position between the second component 16 and the placement unit 11 in a first direction; in the first state, there is a third distance between the second component 16 and the placement unit 11. In this embodiment, when changing from the first state to the second state, the second component 16 or the placement unit 11 moves in the first direction.

[0086] Two sets of transmission components can also be installed on the two side walls of the second component 16 to ensure that the force is uniform during the movement between the second component 16 and the storage unit 11. For details, please refer to the structural configuration of the first component 11 described above, which will not be repeated here.

[0087] In one specific embodiment, the first component 11 is a first permanent magnet, the second component 16 is a second permanent magnet, and the first magnetic field is generated jointly by the first permanent magnet and the second permanent magnet.

[0088] In this embodiment, the first magnetic field is generated jointly by the first permanent magnet and the second permanent magnet. Because permanent magnets possess inherent magnetism and can continuously provide a magnetic field, the first magnetic field they generate is easily unaffected by external interference and can be considered relatively constant; therefore, the first magnetic field is a constant magnetic field. Furthermore, the first component 11 and the second component 16 can generate the first magnetic field without an external power source, which can reduce the energy consumption and operating costs of the food preservation device 100.

[0089] In one specific embodiment, the first component 11 is a permanent magnet and the second component 16 is an electromagnetic coil; or the first component 11 is an electromagnetic coil and the second component 16 is a permanent magnet; the first magnetic field is generated jointly by the permanent magnet and the electromagnetic coil.

[0090] In one specific embodiment, the direction of the first magnetic field generated by the first component at the storage unit is the same as the direction of the second magnetic field generated by the second component at the storage unit.

[0091] In this way, a closed magnetic circuit can be formed, enhancing the magnetic field strength at the storage unit 11 and improving preservation efficiency. In addition, the opposite magnetic poles can also prevent the magnetic field from forming a region with high magnetic resistance at the storage unit 11, ensuring that all parts of the food are subjected to a uniform magnetic field, further improving the preservation effect.

[0092] In one specific embodiment, the first component 11 is a first electromagnetic coil, the second component 16 is a second electromagnetic coil, and the first magnetic field is generated by energizing the first electromagnetic coil and the second electromagnetic coil.

[0093] In one specific embodiment, when the food preservation device 100 is placed vertically on the ground, the first component 12 is positioned above the second component 16. In either the first or second state, the distance between the storage unit 11 and the first component 12 is equal to the distance between the storage unit 11 and the second component 16.

[0094] Thus, by adjusting the distance between the first component 12 and / or the second component 16 and the storage unit, so that in the first or second state, the first component 12 and the second component 16 are arranged in a symmetrical vertical layout, it helps to form a uniform and stable magnetic field environment at the storage unit 11. In addition, the equidistant arrangement ensures that all parts of the food are subjected to the same magnetic field, avoiding differences in preservation effect caused by uneven magnetic field distribution.

[0095] In this embodiment, the first state or the second state can be understood as the positional state of the storage unit 11, the first component 12, and the second component 16 after adjusting the relative position between the first component 12 and the storage unit 11, or adjusting the relative position between the second component 16 and the storage unit 11, or adjusting the relative position between the first component 12, the storage unit 11, and the second component 16 so that the actual magnetic field strength at the storage unit 11 matches the target magnetic field strength.

[0096] In other embodiments, in the first state or the second state, the first component 12 and the second component 16 may also be disposed on the left and right sides of the storage unit 11, and the distance between the storage unit 11 and the first component 12 is equal to the distance between the storage unit 11 and the second component 16.

[0097] Of course, the third distance between the storage unit 11 and the first component 12, and the fourth distance between the storage unit 11 and the second component 16, are not necessarily equal before or after the movement. Specifically, the third distance can be greater than the fourth distance, meaning the storage unit 11 is closer to the second component 16; similarly, the third distance can also be less than the fourth distance, meaning the storage unit 11 is closer to the first component 12. This utility model does not impose specific limitations in this regard.

[0098] like Figure 6 As shown, one embodiment of this utility model provides a refrigeration device 200.
