Description

Technical Field

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

[0002] Refrigeration equipment, such as refrigerators, is a common household appliance 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 magnetic fields also have a certain effect on the preservation and storage of food. Under the action of the magnetic field, it is difficult for small water molecule clusters or ice nuclei formed by single water molecules to aggregate water molecules and grow into large ice crystals in an orderly manner. They appear in the form of micro-ice crystals, which not only promotes the freezing process to pass through the phase change stage quickly, but also reduces the damage of ice crystals to food cells. Therefore, the loss rate of food juice can be reduced, and the nutrition and taste of the food can be better preserved. 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.

[0042] like Figures 1 to 3 As shown, in one embodiment, the refrigeration device 10 includes a housing 100 and a magnetic field device 200. The housing 100 is provided with a storage compartment 101. The magnetic field device 200 is disposed in the storage compartment 101.

[0043] 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.

[0044] Reference Figures 2 to 3 Specifically, the magnetic field device 200 includes a first housing 210, a second housing 220, a shim plate 230, and two magnetic field generating devices 240. The first housing 210 and the second housing 220 interlock and define an installation space. The shim plate 230 is disposed within the installation space. The two magnetic field generating devices 240 are disposed within the installation space and are located on either side of the shim plate 230.

[0045] Reference Figures 2 to 3As shown, the magnetic field device 200 is generally a flat, box-shaped structure. Specifically, the first housing 210 includes a first panel 211 and a first flange 212 disposed at the edge of the first panel 211. The second housing 220 includes a second panel 221 and a second flange 222 disposed at the edge of the second panel 221. The first panel 211, the second panel 221, the first flange 212, and the second flange 222 collectively define an installation space.

[0046] Continue to refer to Figures 2 to 3 As shown, the first panel 211 and the second panel 221 are both substantially square plates, the first flange 212 is formed by the outer edge of the first panel 211 protruding along its own thickness direction, and the second flange 222 is formed by the outer edge of the second panel 221 protruding along its own thickness direction. The area enclosed by the second flange 222 is larger than the area enclosed by the first flange 212. The first shell 210 and the second shell 220 are buckled in the form of the first panel 211 and the second panel 221 facing each other. When the first shell 210 and the second shell 220 are buckled together, the first flange 212 is located on the inner side of the second flange 222 and contacts the second panel 221 (refer to Figure 8 As shown), the first shell 210 and the second shell 220 form an installation space.

[0047] Reference Figures 2 to 3 As shown, the magnetic field generating device 240 is a permanent magnet plate. The ratio of the permanent magnet plate's surface area to the surface area of the shim plate 230 is greater than or equal to 0.8 and less than or equal to 1.5. The shim plate 230 and the two magnetic field generating devices 240 are stacked and placed together between the first housing 210 and the second housing 220. The two magnetic field generating devices 240 are respectively arranged on the side of the shim plate 230 facing the first housing 210 and the second housing 220. In other words, the first housing 210 and the second housing 220 are interlocked along the distribution direction of the two magnetic field generating devices 240.

[0048] Reference Figures 1 to 3 As shown, in addition, the magnetic field device 200 is disposed in the storage compartment 101, and the two magnetic field generating devices 240 face the two opposite side walls of the storage compartment 101, respectively, and there is a space between the side walls of the storage compartment 101 facing the magnetic field generating devices 240. Specifically, the magnetic field device 200 is arranged with the two magnetic field generating devices 240 distributed along the top and bottom directions of the box body 100, that is, the two magnetic field generating devices 240 face the top wall and the bottom wall of the storage compartment 101, respectively. There is a space between the magnetic field device 200 and the top wall and the bottom wall of the storage compartment 101, that is, stored objects can be placed between the magnetic field device 200 and the top wall of the storage compartment 101, and stored objects can also be placed between the magnetic field device 200 and the bottom wall of the storage compartment 101.

[0049] In the solution of this embodiment, by disposing two magnetic field generating devices 240 on either side of the shim plate 230, and placing the structure consisting of the shim plate 230 and the two magnetic field generating devices 240 together in the installation space formed by the first shell 210 and the second shell 220, the first shell 210, the second shell 220, the shim plate 230, and the two magnetic field generating devices 240 can be installed as a whole in the refrigeration device 10 through the fixation between the first shell 210 and the second shell 220, and used to generate a magnetic field in the storage compartment 101 of the refrigeration device 10, thereby achieving magnetic field preservation storage for the stored items in the storage compartment 101 and improving the preservation effect of the stored items. In addition, the two magnetic field generating devices 240 are respectively disposed on either side of the shim plate 230, and the shim plate 230 simultaneously guides the magnetic fields of the two magnetic field generating devices 240, thereby generating a uniform magnetic field on both sides of the magnetic field device 200, simplifying the structure while ensuring the magnetic field effect.

[0050] In addition, the first shell 210 and the second shell 220 can protect the shim plate 230 and the two magnetic field generating devices 240, helping to prevent the shim plate 230 and the two magnetic field generating devices 240 from being directly impacted and damaged. Furthermore, the first shell 210 and the second shell 220 secure the shim plate 230 and the two magnetic field generating devices 240, eliminating the need for adhesive or other means of securing the shim plate 230 and the two magnetic field generating devices 240. This facilitates the separate replacement of the shim plate 230 or the magnetic field generating devices 240, and also facilitates the installation of the shim plate 230 and the two magnetic field generating devices 240 in the refrigeration equipment 10.

[0051] Furthermore, by fastening the first shell 210 and the second shell 220 along the distribution direction of the two magnetic field generating devices 240, the fastened first shell 210 and the second shell 220 can also clamp the uniform magnetic plate 230 and the magnetic field generating devices 240 in the stacking direction of the uniform magnetic plate 230 and the two magnetic field generating devices 240, so that the uniform magnetic plate 230 and the two magnetic field generating devices 240 are closer, thereby improving the guiding effect of the uniform magnetic plate 230 on the magnetic field of the magnetic field generating device 240.

[0052] In addition, by using a larger permanent magnet plate as the magnetic field generating device 240, only two permanent magnet plates are required, which simplifies the overall structure of the magnetic field device 200 and facilitates assembly.

[0053] It should be noted that, in some other embodiments, one of the first shell and the second shell may be a panel with a flange, and the other may be a simple panel. Alternatively, the first shell and the second shell may be two curved panels.

[0054] It should be noted that, in some other embodiments, the magnetic field generating device may also be composed of a plurality of small magnetic pieces, that is, a plurality of scattered small magnetic pieces are respectively provided on both sides of the shim plate.

[0055] In addition, it should be noted that in some other embodiments, when the magnetic field device is provided in the refrigeration equipment, the magnetic field device can also be provided with two magnetic field generating devices facing the left wall and the right wall of the storage compartment respectively.

[0056] like Figures 1 to 7 As shown, the second housing 220 is provided with a plurality of retaining ribs 223. The plurality of retaining ribs 223 surround at least one of the permanent magnet plates and abut against the edges of the permanent magnet plate to position the permanent magnet plate. The plurality of retaining ribs 223 surround the permanent magnet plate, that is, abut against the permanent magnet plate from at least two opposite directions.

[0057] Combine Figures 1 to 8 As shown, the thickness of the retaining rib 223 is greater than the sum of the thicknesses of the shim plate 230 and one permanent magnet plate, so as to simultaneously abut against the edges of the two permanent magnet plates to position the two permanent magnet plates. A notch 231 is provided at the edge of the shim plate 230 for avoiding the retaining rib 223.

[0058] like Figures 1 to 8 As shown, two retaining ribs 223 are provided on each of the four sides of the second housing 220. In other words, the retaining ribs 223 can enclose the permanent magnet plate from four angles, thereby defining the installation position of the permanent magnet plate. The area of the shim plate 230 is larger than the area of the permanent magnet plate. In other words, the shim plate 230 has a portion extending from the center to the periphery of the permanent magnet plate.

[0059] Reference Figures 1 to 8 As shown, the thickness of the rib 223 is the dimension along the distribution direction of the shim plates 230 and the permanent magnet plates, or in other words, the dimension along the thickness direction of the shim plates 230 and the permanent magnet plates. The thickness of the rib 223 is greater than the sum of the thicknesses of the shim plates 230 and one permanent magnet plate, allowing the rib 223 to simultaneously cooperate with both permanent magnet plates. Furthermore, because the shim plates 230 extend beyond the edges of the permanent magnet plates in a direction extending from the center toward the periphery, notches 231 are provided in the portions of the shim plates 230 that extend beyond the edges of the permanent magnet plates to prevent the rib 223 from obstructing the installation of the shim plates 230.

[0060] It will be understood by those skilled in the art that by providing retaining ribs 223 in the first shell 210 or the second shell 220, the retaining ribs 223 can be used to position and fix the permanent magnet plate, making the installation of the permanent magnet plate more convenient. In addition, the permanent magnet plate can be fixed in the installation position to improve the stability of the permanent magnet plate.

[0061] Furthermore, by making the thickness of the retaining rib 223 greater than the combined thickness of the shim plate 230 and one permanent magnet plate, and providing a notch 231 at the edge of the shim plate 230 to accommodate the retaining rib 223, the retaining rib 223 can simultaneously abut against the edges of both permanent magnet plates, thereby positioning the two permanent magnet plates. This helps simplify the structure. Furthermore, the retaining rib 223 and the notch 231 cooperate to position the shim plate 230, thereby facilitating installation of the shim plate 230.

[0062] It should be noted that in some other embodiments, the retaining ribs may also be provided on the first housing. Furthermore, retaining ribs may be provided on both the first housing and the second housing to position the two permanent magnet plates, respectively. Furthermore, the retaining ribs may be less than or equal to the thickness of the permanent magnet plates, thereby preventing interference with the installation of the shim plates.

[0063] Reference Figures 1 to 7 As shown, in one embodiment, the retaining ribs 223 are elastic so as to generate an elastic force directed toward the permanent magnet plate when pressed by the permanent magnet plate, thereby improving the stability of the permanent magnet plate. Specifically, the retaining ribs 223 are capable of elastically deforming from the center of the second housing 220 toward the surrounding area, and the area surrounded by the plurality of retaining ribs 223 is smaller than the outer size of the permanent magnet plate. As a result, after the retaining ribs 223 come into contact with the permanent magnet plate, they are pressed toward the outer periphery of the second housing 220 by the permanent magnet plate, thereby generating elastic deformation, which in turn generates an elastic force that compresses the permanent magnet plate.

[0064] It will be understood by those skilled in the art that by making the retaining rib 223 elastic, the retaining rib 223 can simultaneously generate an elastic force on the permanent magnet plate under the pressure of the permanent magnet plate, thereby increasing the force between the permanent magnet plate and the retaining rib 223 and improving the stability of the permanent magnet plate in the installation position.

[0065] It should be noted that the retaining ribs may be made directly of elastic material, or may be made of a hard material and a spring.

[0066] like Figures 1 to 7 As shown, in one embodiment, the second housing 220 is provided with three positioning posts 224, and the magnetic shim plate 230 and the two permanent magnet plates are provided with through holes (such as Figure 6 The through hole 201 on the shim plate 230 shown in FIG is used to position the installation position of the shim plate 230 and the two permanent magnet plates via the positioning column 224 passing through the through holes of the shim plate 230 and the two permanent magnet plates.

[0067] Reference Figures 1 to 7Specifically, the second panel 221 of the second housing 220 is provided with a positioning post 224 that protrudes toward the first panel 211. The protruding height of the positioning post 224 is greater than the sum of the thicknesses of the shim plate 230 and the one permanent magnet plate. Therefore, when the shim plate 230 and the two permanent magnet plates are stacked together, the positioning post 224 can interfere with both the shim plate 230 and the two permanent magnet plates via the through-holes that align with the shim plate 230 and the two permanent magnet plates.

[0068] Those skilled in the art will appreciate that by providing a plurality of positioning posts 224 in the first shell 210 or the second shell 220, and providing through holes corresponding to the positioning posts 224 in the shim plate 230 and the two permanent magnet plates, the shim plate 230 and the two permanent magnet plates can be positioned by the positioning posts 224 passing through the corresponding through holes of the shim plate 230 and the two permanent magnet plates, thereby facilitating the installation of the shim plate 230 and the two permanent magnet plates. In addition, the positioning posts 224 can also limit the shim plate 230 and the two permanent magnet plates after they are installed in place, thereby improving the stability of the shim plate 230 and the two permanent magnet plates.

[0069] It should be noted that, in some other embodiments, the number of the positioning posts may be two or four or more. In addition, the positioning posts may also be arranged on the first housing.

[0070] It should be noted that, in some embodiments, the positioning post deviates from the central axis of the first shell or the second shell, thereby limiting the unique installation direction of the uniform magnetic plate and the two permanent magnetic plates, ensuring that the magnetic field direction of the two permanent magnetic plates meets the requirements.

[0071] like Figures 1 to 7 As shown, in one embodiment, the second housing 220 is provided with positioning ribs 225. The positioning ribs 225 are used to define an area that is identical in shape and size to the shim plate 230. In other words, the shim plate 230 can be installed precisely within the area enclosed by the positioning ribs 225. Specifically, the positioning ribs 225 have multiple, spaced-apart sections, and the connecting lines of the sections enclose an area that is identical in shape and size to the shim plate 230. Alternatively, the second housing 220 may also be provided with positioning ribs that define an area that is identical in shape and size to one permanent magnet plate, while the first housing 210 may be provided with positioning ribs that define an area that is identical in shape and size to another permanent magnet plate.

[0072] It will be understood by those skilled in the art that by providing positioning ribs 225 on the first shell 210 or the second shell 220, the positioning ribs 225 are used to define an area that has the same shape and size as the uniform magnetic plate 230 or the permanent magnetic plate, thereby positioning the installation of the uniform magnetic plate 230 or the permanent magnetic plate, and facilitating the installation of the uniform magnetic plate 230 or the permanent magnetic plate.

[0073] It should be noted that in some other embodiments, the first shell may be provided with positioning ribs for defining an area with the same shape and size as the uniform magnetic plate, and at the same time, positioning ribs for defining an area with the same shape and size as one permanent magnetic plate may be provided, while the second shell may be provided with positioning ribs for defining an area with the same shape and size as another permanent magnetic plate.

[0074] Reference Figures 2 to 7 As shown, the shim plate 230 and the two permanent magnet plates are generally shaped like a square with one corner missing. That is, the positioning ribs 225 also form a square with one corner missing, so that the installation direction of the shim plate 230 and the permanent magnet plates can be indicated by the positioning ribs 225. Specifically, during installation, the missing corner of the shim plate 230 or the permanent magnet plate is ensured to be aligned with the missing corner of the area enclosed by the positioning ribs 225. That is, the shim plate 230 and the permanent magnet plates are ensured to be installed in the correct direction. This can be used to ensure that the two permanent magnet plates are installed in the correct direction, thereby ensuring that the magnetic field direction of the permanent magnet plates meets the requirements.

[0075] like Figures 2 to 7 ,as well as Figure 9 As shown, the first panel 211 is provided with a hook 213 protruding toward the second panel 221, and the second panel 221 is provided with a hole 226 protruding toward the first panel 211. The hook 213 is inserted into the hole 226 to fix the first shell 210 and the second shell 220. The magnetic shim plate 230 and the two permanent magnet plates are each provided with an escape hole 202 for the hook 213 and the hole 226 to pass through.

[0076] Reference Figures 2 to 7 ,as well as Figure 9 As shown, when the first shell 210 and the second shell 220 are assembled in place, the hook 213 and the hole 226 are buckled together along the distribution direction of the first shell 210 and the second shell 220. The buckled hook 213 and the hole 226 pass through the avoidance hole 202 on the magnetic shim plate 230 and the permanent magnet plate.

[0077] Those skilled in the art will appreciate that by providing the hook 213 on the first panel 211 and the latch hole 226 on the second panel 221, the hook 213 and the latch hole 226 can be engaged along the distribution direction of the first shell 210 and the second shell 220, thereby further strengthening the fit between the first shell 210 and the second shell 220. In addition, the hook 213 and the latch hole 226 pass through the avoidance hole 202 on the shim plate 230 and the permanent magnet plate, thereby achieving a certain positioning and limiting effect on the shim plate 230 and the permanent magnet plate.

[0078] 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.
