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 devices, such as refrigerators, as common household appliances, can store items at low temperatures. With the improvement of people's living standards, higher requirements are put forward for the fresh-keeping effect of refrigeration devices. Theoretical research finds that magnetic fields also have a certain impact on the fresh-keeping storage of food materials. Under the action of a magnetic field, small water molecule clusters or ice nuclei formed by single water molecules are difficult to aggregate water molecules to grow orderly into large ice crystals, and appear in the form of micro ice crystals, which not only promotes the rapid passage of the freezing process through the phase change stage, but also reduces the damage of ice crystals to food cells. Therefore, it can reduce the juice loss rate of food materials and better preserve the nutrition and taste of food materials. Therefore, the refrigeration device field also actively explores the introduction of magnetic fields into fresh-keeping storage for practical application in refrigeration devices.

[0040] As Figures 1 to 9 shown, the refrigeration device 10 includes a box body 100 and a magnetic field device 200. The box body 100 is provided with a storage compartment 101, and a first sliding fitting 300 is arranged on the top wall of the storage compartment 101. The magnetic field device 200 includes a housing 210 and a magnetic field generating member 220. The housing 210 is provided with a second sliding fitting 400. The magnetic field device 200 is slidably fitted with the first sliding fitting 300 via the second sliding fitting 400, and thus is slidably installed on the first sliding fitting 300. The magnetic field generating member 220 is arranged inside the housing 210, and the magnetic field generating member 220 is used to generate a magnetic field in the storage compartment 101.

[0041] It should be noted that the storage compartment 101 of the refrigeration device 10 can be a refrigerated compartment, a frozen 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 functions of the accommodation compartments can be configured according to pre-set requirements. Figure 1 The shown refrigeration device 10 is only an example, and those skilled in the art can configure the specific number, functions, and layout of the storage compartments according to requirements.

[0042] As Figure 1 shown, specifically, the box body 100 has an inner liner and a housing, and a foaming layer is formed between the housing and the inner liner. Figure 1 The inner liner of the box body 100 is shown. The inner liner forms the storage compartment 101, and the first sliding fitting 300 is fixed on the top wall of the inner liner and penetrates through the top wall of the inner liner. The first sliding fitting 300 is sealed with the inner liner to facilitate subsequent foaming processes.

[0043] Referring Figures 1 to 4 shown, the magnetic field device 200 and the first sliding fitting 300 are slidably fitted in the front-rear direction of the box body 100. That is to say, the magnetic field device 200 can be slid to the rear of the box body 100 via the first sliding fitting 300 and assembled into the storage compartment 101, or can be slid to the front of the box body 100 via the first sliding fitting 300 and withdrawn from the storage compartment 101.

[0044] In the solution of this embodiment, by providing a first sliding fitting 300 on the top wall of the storage room 101 and a second sliding fitting 400 on the outer shell 210 of the magnetic field device 200, the magnetic field device 200 can be slidably arranged on the top wall of the storage room 101 via the first sliding fitting 300 and the second sliding fitting 400. After being installed in place, the magnetic field device 200 can generate a magnetic field in the storage room 101 of the refrigeration device 10, thereby realizing magnetic field fresh-keeping storage of the stored items in the storage room 101 and improving the fresh-keeping effect of the stored items. And the sliding installation method makes the disassembly and assembly of the magnetic field device 200 more convenient and improves the convenience of use.

[0045] In addition, the magnetic field device 200 is arranged on the top wall of the storage room 101, which can not only avoid affecting the layout of the internal space of the storage room 101 as much as possible, but also is not easily collided during the process of taking and placing stored items, better protecting the magnetic field device 200. And the outer shell 210 can protect the magnetic field generating part 220 for generating the magnetic field, ensure the safety of the most important magnetic field generating part 220, and also avoid the magnetic field generating part 220 being directly assembled with the first sliding fitting 300 and being damaged due to excessive friction.

[0046] Refer to Figures 1 to 7 and Figure 9 As shown, in one embodiment, the first sliding fitting 300 is provided with two clamping grooves 301, and the two clamping grooves 301 are distributed in the left-right direction of the box body 100 and extend in the front-back direction of the box body 100. The second sliding fitting 400 protrudes from the top of the outer shell 210, and two fitting ribs 410 are provided on the left and right sides of the second sliding fitting 400. The two fitting ribs 410 are slidably fitted with the two clamping grooves 301 in the front-back direction of the box body 100 respectively, so that the magnetic field device 200 is slidably installed on the first sliding fitting 300.

[0047] Refer to Figures 1 to 7 and Figure 9 As shown, specifically, the magnetic field generating part 220 is a permanent magnet piece, and correspondingly, the outer shell 210 is a flat box-shaped structure. Using a permanent magnet piece as the magnetic field generating part 220, compared with an electromagnetic part, there is no need to consider the situation of the wire sliding with the magnetic field device 200, and the structure is simple. The second sliding fitting 400 is a block-shaped structure protruding upward from the top surface of the outer shell 210, and can be integrally formed with the outer shell 210 or a separately formed component fixed to the outer shell 210 later.

[0048] Refer to Figures 1 to 7 and Figure 9As shown in the figure, the clamping groove 301 of the first sliding fitting 300 is composed of two groove walls extending in the left-right direction of the box body 100 and one groove wall extending in the up-down direction of the box body 100. The openings of the two clamping grooves 301 are arranged opposite to each other. The fitting ribs 410 on both sides of the second sliding fitting 400 are respectively inserted into a corresponding clamping groove 301 along the front-back direction of the box body 100, so as to be slidably fitted with the first sliding fitting 300. The groove wall with a certain width of the clamping groove 301 at a lower position in the left-right direction of the box body 100 is used to support the second sliding fitting 400 in the up-down direction, that is, to support the magnetic field device 200.

[0049] In the solution of this embodiment, by providing two clamping grooves 301 on the first sliding fitting 300, the second sliding fitting protrudes from the top of the outer shell 210, so that the second sliding fitting 400 is slidably fitted with the first sliding fitting 300 through the cooperation with the clamping groove 301, so that the magnetic field device 200 is slidably installed on the top wall of the storage room 101. Compared with the clamping groove 301 directly clamping the outer shell 210, the width of the second sliding fitting 400 protruding from the top of the outer shell 210 can be narrower, that is, the distance between the two clamping grooves 301 can be narrower, which helps to simplify the structure of the first sliding fitting 300.

[0050] It should be noted that in some other embodiments, the distance between the two clamping grooves can be set very narrow, so that the second sliding fitting is generally close to a rod shape.

[0051] It should be noted that in some other embodiments, the first sliding fitting can also clamp the left and right sides of the outer shell between the two clamping grooves, that is, the second sliding fitting is the left and right side parts of the outer shell.

[0052] It should be noted that in some other embodiments, it can also be to provide a clamping groove on the second sliding fitting and a fitting rib on the first sliding fitting, that is, one of the first sliding fitting and the second sliding fitting is provided with two clamping grooves, and the left and right sides of the other are provided with two fitting ribs.

[0053] As Figures 1 to 7 shown, the clamping groove 301 has a wide groove part 3011 and a narrow groove part 3012. The width of the wide groove part 3011 is greater than that of the narrow groove part 3012 and along the assembly direction of the fitting rib 410. The wide groove part 3011 is located at the front end of the narrow groove part 3012. The fitting rib 410 has a wide rib part 411 and a narrow rib part 412. The size of the wide rib part 411 is adapted to the width of the wide groove part 3011, and the size of the narrow rib part 412 is adapted to the width of the narrow groove part 3012.

[0054] As Figures 1 to 7As shown, the width of the clamping groove 301 is the dimension in the up-down direction. Along the front-back direction of the box body 100, the width of the clamping groove 301 is not constant, but is wider at the front end and narrower at the rear end. The narrow rib portion 412 of the mating rib 410 is adapted to the narrow groove portion 3012, that is, the dimension of the wide groove portion 3011 in the up-down direction of the box body 100 is greater than the dimension of the narrow rib portion 412 in the up-down direction of the box body 100. Along the assembly direction of the mating rib 410, the wide groove portion 3011 is located at the front end of the narrow groove portion 3012. In other words, during the assembly of the clamping groove 301 and the mating rib 410, the mating rib 410 first enters the wide groove portion 3011 of the clamping groove 301. In this way, during the assembly of the second sliding fitting 400 and the first sliding fitting 300, the narrow rib portion 412 of the mating rib 410 first docks with the wide groove portion 3011 of the clamping groove 301, and it can be more easily initially mated with the clamping groove 301. After being assembled in place, the narrow rib portion 412 is embedded in the narrow groove portion 3012 of the clamping groove 301, and the wide rib portion 411 is embedded in the wide groove portion 3011 to support the magnetic field device 200.

[0055] Those skilled in the art can understand that by providing the wide groove portion 3011 and the narrow groove portion 3012 in the clamping groove 301, and providing the corresponding wide rib portion 411 and narrow rib portion 412 in the mating rib 410, during the assembly of the second sliding fitting 400 and the first sliding fitting 300, the narrow rib portion 412 of the mating rib 410 first mates with the wide groove portion 3011 of the clamping groove 301. Because the wide groove portion 3011 of the clamping groove 301 is wider than the narrow rib portion 412, the mating rib 410 can be more easily initially mated with the clamping groove 301, improving the convenience of assembling the first sliding fitting 300 and the second sliding fitting 400.

[0056] As Figure 6 and Figure 7 shown, there is a guiding portion 3013 with a gradually decreasing width between the wide groove portion 3011 and the narrow groove portion 3012 to guide the narrow rib portion 412 to be embedded in the narrow groove portion 3012. By providing the guiding portion 3013, the narrow rib portion 412 can be smoothly embedded in the narrow groove portion 3012 when contacting the inclined surface of the guiding portion 3012, making the assembly of the second sliding fitting 400 and the first sliding fitting 300 more smooth.

[0057] As Figures 1 to 4 and Figure 8 shown, a locking structure 500 is provided between the first sliding fitting 300 and the second sliding fitting 400. The locking structure 500 in the locked state restricts the sliding of the magnetic field device 200 relative to the first sliding fitting 300 to fix the magnetic field device 200 at the set installation position.

[0058] As Figures 1 to 4 and Figure 8 shown, the locking structure 500 includes a knob 510 and a locking groove 501. The knob 510 is disposed on the second sliding fitting 400, and the locking groove 501 is disposed on the first sliding fitting 300. The knob 510 is inserted into the locking groove 501 so that the locking structure 500 is in a locked state, and the knob 510 is switched between a position where it is inserted into the locking groove 501 and a position where it is disengaged from the locking groove 501 by rotation.

[0059] Referring to Figures 1 to 4 and Figure 8 shown, the knob 510 is rotatably disposed on a surface of the second sliding fitting 400 facing the front side of the box body 100, and the locking groove 501 is disposed on a surface of the first sliding fitting 300 facing the second sliding fitting 400, with the notch facing downwards. The knob 510 is similar to a rectangle, that is, the length is greater than the width. When the length direction of the knob 510 extends vertically, the top end of the knob 510 protrudes beyond a part of the top surface of the second sliding fitting portion 400, and when the width direction of the knob 510 extends vertically, the knob 510 does not protrude beyond the top surface of the second sliding fitting portion 400.

[0060] Referring to Figures 1 to 4 and Figure 8 shown, during the assembly process of the second sliding fitting 400 and the first sliding fitting 300, first, the knob 510 is in a state where the width direction extends vertically (refer to the state shown in Figure 4 ), and then the assembly work of the second sliding fitting 400 and the first sliding fitting 300 is started. After the second sliding fitting 400 and the first sliding fitting 300 are assembled in place, at this time, the locking groove 501 is exactly above the knob 510. Rotate the knob 510 to a state where the length direction extends vertically (refer to the state shown in Figure 3 , that is, rotate the knob 510 clockwise from the state shown in Figure 4 ), and a part of the knob 510 that protrudes beyond the top surface of the second sliding fitting portion 400 can be inserted into the locking groove 501, so that the locking structure 500 is in a locked state. In this way, the magnetic field device 200 cannot slide forward of the box body 100 and is fixed at the set installation position. When it is necessary to remove the magnetic field device 200, rotate the knob 510 counterclockwise from the state shown in Figure 3 , and the knob 510 can reach the state of disengaging from the locking groove 501 shown in Figure 4 , and then the magnetic field device 200 can be removed.

[0061] Those skilled in the art can understand that by providing a locking structure 500 between the first sliding fitting 300 and the second sliding fitting 400, the magnetic field device 200 can be restricted to the set installation position, preventing the magnetic field device 200 from sliding after being installed in place and causing collisions, thereby improving the safety of using the magnetic field device 200. Additionally, by using the knob 510 and the locking groove 501 to form the locking structure 500, the structure is relatively simple and the operation is relatively convenient.

[0062] It should be noted that in some other embodiments, the locking structure can also be an electromagnetic device provided on the first sliding fitting. After the second sliding fitting and the first sliding fitting are assembled in place, the electromagnetic device is powered on, and thus the magnetic field device is fixed by the magnetic attraction force between the electromagnetic device and the magnetic field generating member. Alternatively, the locking structure can also be a sliding member provided on one of the first sliding fitting and the second sliding fitting and a slot hole structure provided on the other, and the magnetic field device is locked by the sliding member being inserted into the slot hole structure, such as a bolt structure, etc.

[0063] As Figure 1 and Figure 9 shown, in one embodiment, the housing 210 includes a first housing 211 and a second housing 212. The first housing 211 and the second housing 212 are fastened along the up and down direction of the box body 100, and the first housing 211 is located above the second housing 212. The magnetic field generating member 220 is provided between the first housing 211 and the second housing 212.

[0064] Referring to Figure 1 and Figure 9 shown, both the first housing 211 and the second housing 212 are structures formed by setting flanges in the same direction on the four side edges of a square plate. The first housing 211 and the second housing 212 are fastened and spliced together in a way that the sides with flanges face each other, thereby jointly enclosing a square installation space. The magnetic field generating member 220 is provided in the installation space enclosed by the first housing 211 and the second housing 212. The first housing 211 and the second housing 212 are detachably fixed together. For example, the first housing 211 and the second housing 212 are spliced using a snap structure.

[0065] In the solution of this embodiment, by setting the housing 210 as a structure jointly composed of the first housing 211 and the second housing 212, while protecting the magnetic field generating member 220, it also facilitates the installation of the magnetic field generating member 220 in the housing 210 and the removal of the magnetic field generating member 220 from the housing 210.

[0066] As Figure 1 and Figure 9As shown, in one embodiment, the magnetic field device 200 further includes a magnetic field homogenizing plate 230, which is disposed on the side of the magnetic field generating member 220 facing the top wall of the storage compartment 101. Specifically, the magnetic field homogenizing plate 230 is disposed in a fitting manner with the plate-shaped magnetic field generating member 220, and the projection of the magnetic field generating member 220 on the surface of the magnetic field homogenizing plate 230 completely falls on the magnetic field homogenizing plate 230. By providing the magnetic field homogenizing plate 230, the magnetic field generated by the magnetic field generating member 220 can be guided, making the magnetic field distribution more uniform.

[0067] It should be noted that, in some other embodiments, only the magnetic field generating member may be provided. Additionally, in some other embodiments, the magnetic field generating member may be an electromagnetic coil. Alternatively, the magnetic field generating member may include a plurality of permanent magnet pieces.

[0068] As Figure 9 and Figure 10 As shown, in one embodiment, the second sliding fitting member 400 is integrally formed separately from the outer shell 210. The top of the outer shell 210 is provided with a plurality of positioning grooves 213. The bottom of the second sliding fitting member 400 is provided with a corresponding number of positioning ribs 420. The second sliding fitting member 400 is disposed on the top of the outer shell 210, and the positioning ribs 420 are inserted into the positioning grooves 213. Specifically, the positioning grooves 213 extend along the left-right direction of the refrigerator, and the plurality of positioning grooves 213 are spaced apart along the front-back direction of the refrigerator. The positioning ribs 420 correspond to the positioning grooves 213 one by one and are inserted into the corresponding positioning grooves 213.

[0069] Since the outer shapes of the second sliding fitting member 400 and the outer shell 210 are relatively regular, but the combined structure is relatively complex, by integrally forming the second sliding fitting member 400 separately from the outer shell 210, it helps to simplify the production template and improve production efficiency. And by providing a plurality of positioning grooves 213 on the top of the outer shell 210 and a corresponding number of positioning ribs 420 on the bottom of the second sliding fitting member 400, the installation position of the second sliding fitting member 400 on the outer shell 210 can be positioned by using the cooperation between the positioning ribs 420 and the positioning grooves 213, facilitating the assembly work of the second sliding fitting member 400 and the outer shell 210.

[0070] In addition, the second sliding fitting member 400 and the outer shell 210 can be fixed together by an adhesive. At this time, the positioning ribs 420 and the positioning grooves 213 can also increase the contact surface, thereby making the bonding between the second sliding fitting member 400 and the outer shell 210 more firm.

[0071] At this point, those skilled in the art should recognize that although numerous exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived based on the content disclosed in the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and determined to cover all such other variations or modifications.
