Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a refrigeration device. Background Art

[0002] Refrigeration equipment, such as refrigerators, are common household appliances that can store items at low temperatures. With the improvement of people's living standards, higher requirements are placed on the preservation effect of refrigeration equipment. Theoretical studies have found that the magnetic field has a great influence on the formation of ice crystals during the freezing process. The magnetic field restricts the free path of water molecules to a certain extent, which is manifested as the breaking of hydrogen bonds in water molecule clusters. During the phase change process, the growth of the crystal nucleus is inhibited, the growth rate of ice crystals is higher than the migration rate of water molecules, and the resulting ice crystals are smaller, which causes less damage to cells, reduces the juice loss rate, and better preserves the nutrition and taste of food. Therefore, the field of refrigeration equipment is also actively exploring the introduction of magnetic fields into fresh-keeping storage for practical application in refrigeration equipment.

DETAILED DESCRIPTION

[0035] Those skilled in the art should understand that the embodiments described below are only a portion of the embodiments of the present invention, rather than all of the embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "radial", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] like Figures 1 to 3As shown, in one embodiment, a refrigeration device 10 includes a housing 100 and a magnetic field device 200. The housing 100 defines a storage compartment 101. The magnetic field device 200 is disposed on the bottom wall of the storage compartment 101 and includes a first housing 210, a second housing 220, and a magnetic field generator 230. The first housing 210 and the second housing 220 are joined to define an installation space, and the magnetic field generator 230 is disposed in the installation space and is used to generate a magnetic field within the storage compartment 101.

[0039] It should be noted that the storage compartment 101 of the refrigeration device 10 can be a refrigerator compartment, a freezer compartment, a variable temperature compartment, etc. In addition, the refrigeration device 10 can be provided with multiple storage compartments 101, and the specific number and function of the storage compartments can be configured according to pre-determined requirements. Figure 1 The refrigeration device 10 shown is only an example, and those skilled in the art can configure the specific number, function and layout of the storage compartments according to needs.

[0040] Reference Figures 1 to 3 As shown, the magnetic field device 200 is a flat, square box-shaped structure. Specifically, the first shell 210 and the second shell 220 are each formed by having flanges disposed in the same direction on the four sides of a square plate. The first shell 210 and the second shell 220 are snapped together and spliced together with their flanged sides facing each other, thereby forming a square installation space.

[0041] Continue to refer to Figures 1 to 3 As shown, the magnetic field generating element 230 is used to generate a magnetic field. The magnetic field generating element 230 is a plate-shaped permanent magnet, so that it can be set in the installation space. The first shell 210 and the second shell 220 are detachably fixed together. For example, the first shell 210 and the second shell 220 are spliced together using a snap-fit structure.

[0042] In this embodiment, magnetic field device 200 is constructed by disposing magnetic field generator 230 within the mounting space formed by first housing 210 and second housing 220. Furthermore, magnetic field device 200 is positioned on the bottom wall of storage compartment 101. This allows magnetic field generator 230 to generate a magnetic field within storage compartment 101, thereby maintaining the freshness of stored items within storage compartment 101 through magnetic field preservation, thereby improving the freshness of the stored items. Furthermore, the bottom wall of storage compartment 101 provides excellent support for magnetic field device 200, facilitating its installation and securing. This eliminates the need for additional support structures and contributes to a simplified structure.

[0043] Furthermore, the first shell 210 and the second shell 220 protect the magnetic field generator 230. Even if items are placed directly on the bottom wall of the storage compartment 101, this prevents the items from directly contacting the magnetic field generator 230 and potentially damaging it. Furthermore, even if liquid in the storage compartment 101, such as condensed water or food juice, falls onto the bottom wall of the storage compartment 101, the first shell 210 and the second shell 220 prevent the liquid from directly contacting the magnetic field generator 230 and potentially corroding it, thereby extending the service life of the magnetic field generator 230 disposed on the bottom wall of the storage compartment 101.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, the magnetic field device 200 further includes a shim plate 240, which is disposed on the side of the magnetic field generator 230 that faces the bottom wall of the storage compartment 101. Specifically, the shim plate 240 and the plate-shaped magnetic field generator 230 are positioned in close contact with each other, and the projection of the magnetic field generator 230 on the surface of the shim plate 240 completely falls on the shim plate 240. The shim plate 240 guides the magnetic field generated by the magnetic field generator 230, resulting in a more uniform magnetic field distribution.

[0045] It should be noted that, in some other embodiments, only the magnetic field generating element may be provided. In addition, in some other embodiments, the magnetic field generating element may also be an electromagnetic coil.

[0046] like Figures 1 to 9 As shown, in one embodiment, the magnetic field device 200 is removably secured to the bottom wall of the storage compartment 101. Specifically, a first housing 210 is disposed on a side of the second housing 220 facing away from the bottom wall of the storage compartment 101. The first housing 210 is provided with a first mounting hole 211, and the second housing 220 is provided with a clearance hole 221 that avoids the first mounting hole 211. The bottom wall of the storage compartment 101 is provided with a second mounting hole 102. The magnetic field device 200 is removably secured to the bottom wall of the storage compartment 101 by a securing device that sequentially penetrates the first mounting hole 21, the clearance hole 221, and the second mounting hole 102.

[0047] Reference Figures 1 to 9As shown, that is, the first shell 210 and the second shell 220 are distributed along the up-down direction of the box body 100. The first shell 210 is provided with a first mounting hole 211 extending in the up-down direction, and the second shell 220 is provided with a second mounting hole 221 extending in the up-down direction. The first mounting hole 211 and the second mounting hole 221 are aligned in the up-down direction. The bottom wall of the storage compartment 101 is provided with a second mounting hole 102 extending in the up-down direction. The first mounting hole 211 and the second mounting hole 102 are aligned in the up-down direction. The fixing device can be a screw, which is sequentially passed through the first mounting hole 21, the avoidance hole 221 and the second mounting hole 102, so that the magnetic field device 200 and the bottom wall of the storage compartment 101 are detachably fixed.

[0048] Those skilled in the art will appreciate that by removably securing magnetic field device 200 to the bottom wall of storage compartment 101, maintenance and replacement of magnetic field device 200 are facilitated. Furthermore, by providing first mounting hole 211 in first housing 210, second mounting hole 221 in second housing 220, and second mounting hole 102 in the bottom wall of storage compartment 101, magnetic field device 200 can be removably secured to the bottom wall of storage compartment 101 using a securing device that sequentially penetrates first mounting hole 21, avoidance hole 221, and second mounting hole 102, resulting in a relatively simple securing structure.

[0049] It should be noted that, in some other embodiments, the magnetic field device and the bottom wall of the storage compartment may also be fixed using other detachable structures such as a snap structure.

[0050] like Figures 1 to 9 As shown, the first housing 210 is provided with a raised portion 212 that protrudes toward the second housing 220. The raised portion 212 is disposed through the avoidance hole 221, and the first mounting hole 211 is disposed in the raised portion 212. Specifically, the raised portion 212 is generally cylindrical, and the first mounting hole 211 is disposed on the end surface of the raised portion 212. The radial dimension of the avoidance hole 221 is equal to or greater than the radial dimension of the raised portion 212, allowing the raised portion 212 to extend into the avoidance hole 221.

[0051] Those skilled in the art will appreciate that, by providing a protrusion 212 protruding toward the second shell 220 on the first shell 210 and providing the first mounting hole 211 on the protrusion 212, the magnetic field device 200 can be detachably fixed to the bottom wall of the storage compartment 101, and the positioning function between the first shell 210 and the second shell 220 can be achieved by utilizing the cooperation between the protrusion 212 and the avoidance hole 221, thereby facilitating the installation of the first shell 210 and the second shell 220.

[0052] like Figures 1 to 6As shown, the first mounting hole 211 and the avoidance hole 221 are arranged near the sides of the first shell 210 and the second shell 220. The edge of the magnetic field generating element 230 is provided with a avoidance area 231 for avoiding the first mounting hole 211 and the avoidance hole 221. Specifically, the avoidance area 231 is a semicircular area formed by a recessed center of the side of the magnetic field generating element 230, thereby matching the outer periphery of the circular avoidance hole 221.

[0053] Those skilled in the art will appreciate that by arranging the first mounting hole 211 and the avoidance hole 221 near the sides of the first shell 210 and the second shell 220, and arranging an avoidance area 231 on the edge of the magnetic field generating element 230 for avoiding the first mounting hole 211 and the avoidance hole 221, the avoidance area 231 can be used to position the installation of the magnetic field generating element 230, thereby facilitating the assembly of the magnetic field generating element 230 with the first shell 210 and the second shell 220.

[0054] In addition, the avoidance area 231 can be set at a position deviated from the central axis of the magnetic field generating element 230, so that the avoidance area 231 can also determine the unique installation direction of the magnetic field generating element 230, thereby determining the magnetic field direction of the magnetic field generating element 230.

[0055] In the case where a shim plate is provided, the shim plate is also provided with a avoidance zone with reference to the magnetic field generating element.

[0056] It should be noted that a through hole offset from the center point may be provided in the magnetic field generating element, and a vertical rod corresponding to the through hole may be provided in the first shell or the second shell to determine the installation direction of the magnetic field generating element.

[0057] like Figures 1 to 5 ,as well as Figures 7 to 9 As shown, one of the bottom wall of the storage compartment 101 and the magnetic field device 200 is provided with a positioning post 120, and the other is provided with a guide structure 222. The guide structure 222 is used to cooperate with the positioning post 120 to locate the installation position of the magnetic field device 200 relative to the bottom wall of the storage compartment 101. Specifically, the positioning post 120 is provided on the bottom wall of the storage compartment 101, and the guide structure 222 is provided on the side of the magnetic field device 200 facing the bottom wall of the storage compartment 101.

[0058] Reference Figures 1 to 5 ,as well as Figures 7 to 9 As shown, the guide structure 222 is a guide track with one end closed, and the width of the guide track decreases from the open end to the closed end. The magnetic field device 200 is positioned relative to the bottom wall of the storage compartment 101 by the positioning column 120 against the closed end of the guide track.

[0059] Continue to refer to Figures 1 to 5 ,as well as Figures 7 to 9As shown, the guide rail is provided on the surface of the bottom wall of the magnetic field device 200 facing the storage compartment 101, that is, on the surface of the bottom wall of the second housing 220 facing the storage compartment 101. The open end and the closed end of the guide rail are distributed along the front-to-back direction of the box body 100, with the open end being provided toward the front side of the box body 100.

[0060] Reference Figures 1 to 5 ,as well as Figures 7 to 9 As shown, in this way, when installing the magnetic field device 200 on the bottom wall of the storage compartment 101, the magnetic field device 200 can first be placed against the bottom wall of the storage compartment 101 and placed at a position close to the rear side of the box body 100 relative to the final position, and then the magnetic field device 200 can be moved toward the front of the box body 100. During this process, the open end of the guide rail continuously approaches the positioning post 120. Because the open end of the guide rail is relatively wide, even if the magnetic field device 200 is not completely aligned with the final position in the front-to-back direction, the guide rail can still contact the positioning post 120. Then, due to the interference relationship between the gradually narrowing sidewalls of the guide rail and the positioning post 120, the magnetic field device 200 is forced to move to a position aligned with the final position, thereby completing the positioning installation of the magnetic field device 200.

[0061] Those skilled in the art will appreciate that by providing a guide structure 222 on the magnetic field device 200 and a positioning post 120 on the bottom wall of the storage compartment 101, the magnetic field device 200 can be positioned via the guide structure 222 and the positioning post 120, facilitating installation of the magnetic field device 200 in the desired position and ensuring that the magnetic field acts on the effective area. Furthermore, the guide structure 222 and the positioning post 120 can also limit the magnetic field device 200 in the lateral direction after installation, preventing the magnetic field device 200 from moving out of the installation position. Furthermore, by providing the guide structure 222 as a guide rail, the structure is relatively simple.

[0062] It should be noted that the magnetic field device 200 may be provided with a plurality of guide structures 222 , and correspondingly, a plurality of positioning posts 120 may be provided on the bottom wall of the storage compartment 101 .

[0063] It should be noted that, in some other embodiments, the open end of the guide rail may also be arranged toward the rear side of the box body, and the installation direction is opposite to that of the above embodiment.

[0064] It should be noted that, in some other embodiments, the guide rail can also be set on the bottom wall of the storage compartment, and the positioning column is set on the magnetic field device. If the open end of the guide rail faces the rear side of the box, the installation direction is the same as the above embodiment. If the open end of the guide rail faces the front side of the box, the installation direction is opposite to the above embodiment.

[0065] It should be noted that, in some other implementations, the guiding structure may also be a tapered surface extending in the longitudinal direction, that is, an annular surface with a decreasing longitudinal diameter, which can also cooperate with the positioning post to play a positioning role.

[0066] Reference Figures 1 to 5 ,as well as Figures 7 to 9 As shown, in some embodiments, a first limiting portion 121 extending radially outward is provided at one end of the positioning post 120 facing the guide rail, and second limiting portions 223 extending inward are respectively provided on two opposing inner sidewalls of the guide rail. The spacing between the two second limiting portions 223 is greater than or equal to the width of the portion of the positioning post 120 outside the first limiting portion 121, and less than the width of the first limiting portion 121. This allows the first limiting portion 121 to cooperate with the magnetic field device 200 in the longitudinal direction after the positioning post 120 is properly engaged with the guide rail.

[0067] Continue to refer to Figures 1 to 5 ,as well as Figures 7 to 9 As shown, the first limiting portion 121 is formed by extending in two opposite directions from at least the top portion of the positioning post 120. The second limiting portion 223 is formed by extending from the inner sidewall of the guide rail toward the other opposite inner sidewall and is spaced a certain distance from the bottom surface of the magnetic field device 200 so that the first limiting portion 121 enters between the second limiting portion 223 and the bottom surface of the magnetic field device 200.

[0068] Reference Figure 9 As shown, when the magnetic field device 200 is installed in place on the bottom wall of the storage compartment 101, the first limiting portion 121 is located between the second limiting portion 223 and the bottom surface of the magnetic field device 200, and the first limiting portion 121 and the second limiting portion 223 overlap in the up and down directions. Therefore, the first limiting portion 121 and the second limiting portion 223 can limit the magnetic field device 200 in the up and down directions, thereby improving the stability of the magnetic field device 200 after installation.

[0069] It should be noted that a guide surface inclined up and down may be provided on one end of the second limiting portion facing the open end of the guide track, so that the first limiting portion can be more easily matched with the second limiting portion.

[0070] Reference Figures 1 to 5 ,as well as Figures 7 to 9 As shown, the second mounting hole 102 can be provided on the positioning post 120 , so that the positioning post 120 can be used for both positioning and fixing the magnetic field device 200 , which helps to simplify the structure.

[0071] like Figure 1 and Figure 10As shown, in one embodiment, the bottom wall of the storage compartment 101 is tilted in the front-to-back direction, thereby causing the magnetic field device 200 to be tilted as well. By tilting the bottom wall of the storage compartment 101 in the front-to-back direction, the magnetic field device 200 is also tilted. This allows liquid that falls on the magnetic field device 200 to flow downward along the tilted direction, preventing the liquid from being dispersed on the magnetic field device 200, thereby facilitating cleaning of the magnetic field device 200.

[0072] It should be noted that a water collecting trough may be provided at a lower position in the tilting direction of the magnetic field device to collect the flowing liquid.

[0073] In addition, when the magnetic field device is provided with a guide rail extending in the front-to-back direction and opening toward the front side of the refrigerator, the inclined setting of the magnetic field device also helps the magnetic field device to press on the positioning column by its own gravity, making the magnetic field device more stable.

[0074] Reference Figure 1 and Figure 10 As shown, the bottom wall of the storage compartment 101 can be provided with multiple magnetic field devices 200, distributed along the front-to-back direction of the storage compartment 101. The portion of the bottom wall of the storage compartment 101 used to house the magnetic field devices 200 at the rear is tilted at a greater angle than the portion of the bottom wall used to house the magnetic field devices 200 at the front. In other words, the tilt angle of the magnetic field devices 200 at the rear is greater than the tilt angle of the magnetic field devices 200 at the front. In this way, the multiple magnetic field devices 200 can generate magnetic fields in the storage compartment 101 from multiple directions, thereby improving the magnetic field effect.

[0075] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
