Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a refrigeration device. Background Technology

[0002] The refrigeration unit includes a housing, a door, and a door shelf. The housing has a refrigerated compartment for storing goods. The door is foldable and can be opened and closed over the housing. The door shelf is located inside the door for supporting goods.

[0003] In related technologies, door shelves are connected to the door body so that the door body can support the door shelves. However, the position of the door shelves relative to the door body is fixed, and the vertical position of the door shelves cannot be adjusted, making it inconvenient for the door shelves to support goods of different heights and affecting the efficiency of the refrigeration unit. Utility Model Content

[0004] One objective of this application is to provide a refrigeration device that can adjust the position of a door shelf vertically to effectively improve the efficiency of the refrigeration device.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: According to one aspect of this application, a refrigeration device is provided, comprising: a housing, a door, a door shelf, a second magnetic element, and an adjustment assembly; the door is closable and covers the housing; a plurality of engaging slots are provided on the inner side of the door, spaced apart in a vertical direction, and a first magnetic element is disposed in each engaging slot; the door shelf is disposed on the inner side of the door, and a passageway is provided in the door shelf corresponding to the engaging slots; the second magnetic element is movably disposed in the passageway; the opposing ends of the second magnetic element and the first magnetic element are magnetically attracted to each other, so that the end of the second magnetic element can be detachably inserted into the engaging slot. The door shelf has an adjustment assembly connected to its bottom. This assembly is connected to a second magnetic element, allowing it to apply a force away from the first magnetic element to the second magnetic element. When the door shelf is adjusted vertically so that the passageway is aligned with any of the engaging slots, the second magnetic element can extend into the engaging slot under the magnetic force of the first magnetic element, thus confining the door shelf to the door body. The adjustment assembly can drive the second magnetic element away from the first magnetic element and disengage it from the engaging slot, thereby adjusting the vertical position of the door shelf.

[0006] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, when the door shelf moves up and down to a preset position, the second magnetic component is positioned opposite to the first magnetic component in a locking groove. Under the magnetic force of the first magnetic component, the second magnetic component moves towards the first magnetic component, so that a portion of the second magnetic component extends into the locking groove. This allows the door shelf to be connected to the door body via the second magnetic component, thereby adjusting the up and down position of the door shelf. This enables the door shelf to hold items of different heights, improving the versatility of the refrigeration device.

[0007] In some embodiments, the adjustment assembly includes a third magnetic element and an adjustment element, the adjustment element being connected to the third magnetic element to move the third magnetic element closer to or away from the port of the passageway away from the engaging slot; the magnetic force between the third magnetic element and the second magnetic element is greater than the magnetic force between the second magnetic element and the first magnetic element; when the third magnetic element approaches the port of the passageway, the second magnetic element disengages from the engaging slot under the magnetic force of the third magnetic element.

[0008] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, when the adjusting member can move the third magnetic member closer to or further away from the port of the passageway 321, the second magnetic member can be separated from the first magnetic member under the magnetic force of the third magnetic member and disengage from the locking groove, thereby adjusting the position of the door shelf in the vertical direction and realizing the rapid adjustment of the second magnetic member.

[0009] In some embodiments, the adjustment assembly further includes a movable column movably connected to the bottom of the door shelf, the movable column moving in a direction perpendicular to the extension direction of the passageway; the movable column has an embedding groove for accommodating and limiting the third magnetic element; the adjustment member is throttledly connected to the movable column, and the adjustment member can drive the movable column to move so as to move the third magnetic element closer to or away from the port of the passageway.

[0010] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, the movable column can move the third magnetic component closer to or away from the port of the passageway, and the third magnetic component is embedded in the movable column, so that the protective column can protect the third magnetic component and prevent the third magnetic component from being impacted or bumped during use and maintenance.

[0011] In some embodiments, the adjusting assembly further includes at least one transmission gear disposed between the moving column and the adjusting member; the moving column is provided with a rack portion that meshes with the transmission gear; the rack portion extends in a direction parallel to the moving direction of the moving column; the adjusting member is rotatably connected to the door shelf, the adjusting member is provided with a gear portion that meshes with the transmission gear, and the rotation axis of the adjusting member is parallel to the rotation axis of the transmission gear.

[0012] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, the transmission gear can mesh with the moving column and the adjusting member respectively, so as to change the rotation direction of the adjusting member, thereby making it easier for the user to apply force to the adjusting member by hand and improving the operating efficiency of the adjusting component.

[0013] In some embodiments, the adjustment assembly further includes an elastic element located between the adjustment member and the door shelf, the elastic element being capable of applying an elastic force to the adjustment member to cause the adjustment member to move the movable column away from the passageway.

[0014] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, when the adjusting component rotates, the elastic component absorbs the rotational kinetic energy of the adjusting component and converts it into elastic potential energy. When the user stops applying external force to the adjusting component, the elastic component can apply an elastic force to the adjusting component, causing the adjusting component to drive the moving column away from the passageway through the transmission gear, thereby separating the third magnetic component from the second magnetic component. This effectively improves the automation level of the adjusting component and enhances the efficiency and ease of use of the refrigeration device.

[0015] In some embodiments, the door shelf includes a shelf body and a protective shell disposed at the bottom of the shelf body, the protective shell and the shelf body enclosing a working space, and the adjustment component being located within the working space.

[0019] In some embodiments, the protective shell and / or the shelf body are provided with two limiting ribs, which are spaced apart along the extension direction of the passageway and extend along the moving direction of the moving column. The two limiting ribs are located on opposite sides of the moving column to abut and limit the moving direction of the moving column.

[0020] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, the two limiting ribs can be located on opposite sides of the moving column, thereby limiting the moving direction of the moving column and ensuring the stable and safe operation of the adjustment component.

[0021] In some embodiments, the protective shell has a control groove, and the end of the adjustment member away from the third magnetic member extends out of the protective shell through the control groove.

[0022] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, the peripheral sidewall of the control slot can abut against the adjustment component to limit the adjustment stroke of the adjustment component, ensuring that the second magnetic component can disengage from the locking slot under the action of the adjustment component, thus ensuring the stability and reliability of the refrigeration device.

[0040] Figure 1 This is a schematic diagram of the structure of the refrigeration device of this utility model. Figure 2 yes Figure 1 The diagram shows the structure after the box body has been removed. Figure 3 yes Figure 2 The diagram shows a structural schematic from another perspective.

[0041] See Figure 1 , Figure 2 and Figure 3 In this embodiment, the refrigeration device may include a housing 100, a door 200, and a door shelf 300. The housing 100 has a refrigeration compartment 110 for storing items. The door 200 is closable on the housing 100 to open or close the refrigeration compartment 110. The door shelf 300 is located inside the door 200 to support items, thereby allowing the space inside the refrigeration device to hold more items and effectively improving the space utilization rate of the refrigeration device.

[0042] See Figure 1 For ease of understanding and description, the state of the user using the refrigeration device is taken as a reference. The vertical direction of the cabinet 100 is the vertical direction of the following text. The direction of the user relative to the refrigeration device is the front of the following text. The direction away from the front is the rear of the following text. The direction perpendicular to the vertical and front-back directions is the left-right direction of the following text.

[0043] Figure 4This is a structural schematic diagram of the door body of this utility model.

[0044] See Figure 4 In this embodiment, the door 200 is disposed on the front side of the housing 100. Multiple engaging slots 220, arranged at intervals along the vertical direction, may be provided on the inner side of the door 200. These multiple engaging slots 220 are used to connect with the door shelf 300 respectively, thereby enabling adjustment of the position of the door shelf 300 in the vertical direction.

[0045] See Figure 4 In this embodiment, two supporting ribs 210 extending vertically may protrude from the inner side of the door body 200. The two supporting ribs 210 are respectively located on the left and right sides of the door body 200. Each of the two supporting ribs 210 is provided with multiple engaging grooves 220 for connecting with the door shelf 300, thereby effectively improving the connection strength and reliability between the door shelf 300 and the door body 200, and preventing the door shelf 300 from accidentally detaching from the door body 200.

[0046] In some embodiments, the opening directions of the engaging grooves 220 on the two support ribs 210 are arranged facing each other to improve the connection strength and reliability between the door shelf 300 and the door body 200.

[0047] Figure 5 This is the book Figure 4 The diagram shows the structure after the door body is removed.

[0048] See Figure 4 and Figure 5 In this embodiment, each of the multiple engagement slots 220 is provided with a first magnetic element 230 to improve the connection strength and reliability between the door body 200 and the door shelf 300.

[0049] In some embodiments, the first magnetic element 230 may be made of neodymium iron boron magnet, ferrite magnet or samarium cobalt magnet.

[0050] Figure 6 This is a schematic diagram of the structure of the door shelf, adjustment component and second magnetic component of this utility model after removing one of the protective shells. Figure 7 This is a schematic diagram of the structure of the two protective shells, two second magnetic components and two adjustment components of this utility model.

[0051] See Figure 5 , Figure 6 and Figure 7 In this embodiment, the cooling device may further include a second magnetic element 410. The second magnetic element 410 is movably disposed through the door shelf 300 so as to be able to approach or move away from the first magnetic element 230, thereby being able to extend into or disengage from the engaging groove 220. The second magnetic element 410 and the first magnetic element 230 are magnetically attracted to each other.

[0052] When the door shelf 300 moves up and down to the preset position, the second magnetic element 410 is positioned opposite to the first magnetic element 230 in the engaging groove 220. Under the magnetic force of the first magnetic element 230, the second magnetic element 410 moves toward the first magnetic element 230, so that a portion of the second magnetic element 410 extends into the engaging groove 220, thereby connecting the door shelf 300 to the door body 200 through the second magnetic element 410, thus limiting the door shelf 300 to the preset position.

[0053] When the door shelf 300 needs to be adjusted in height, the user applies force to the second magnetic element 410 so that the force is greater than the magnetic force between the second magnetic element 410 and the first magnetic element 230, thereby causing the second magnetic element 410 to disengage from the engaging groove 220, and the door shelf 300 can move up and down to adjust its height.

[0054] In some embodiments, the second magnetic element 410 may be made of neodymium iron boron magnet, ferrite magnet or samarium cobalt magnet.

[0055] See Figure 6 and Figure 7 In this embodiment, the cooling device may include two second magnetic elements 410. The two second magnetic elements are movably disposed on the left and right sides of the bottom of the door shelf 300, so that the two second magnetic elements 410 can respectively correspond to the multiple engaging slots 220 on the two support ribs 210. The two second magnetic elements 410 can respectively extend into the engaging slots 220 on both sides of the door body 200 and connect with the first magnetic element 230 within the engaging slots 220, thereby improving the connection strength and reliability between the door shelf 300 and the door body 200.

[0056] In some embodiments, the second magnetic element 410 can extend in the left-right direction and can move in the left-right direction so that the two second magnetic elements 410 can respectively extend into or disengage from the adjacent engaging slots 220 on the left and right sides of the door body 200.

[0057] In other embodiments, the extension direction of the second magnetic element 410 may have an angle of 0° to 60° with the left and right directions, so that the second magnetic element 410 can move along its own extension direction and extend into the engaging groove 220, thereby limiting the door shelf 300 to the door body 200.

[0058] See Figure 2 In this embodiment, a storage slot 311 may be provided on the upper side of the door shelf 300 to accommodate items, thereby improving the space utilization of the refrigeration device.

[0059] The bottom of the door shelf 300 can be provided with a passageway 321 corresponding to the engaging groove 220. The passageway 321 is used to accommodate the second magnetic element 410, so as to limit the second magnetic element 410 to slide left and right only within the passageway 321, and to be able to extend into or out of the engaging groove 220.

[0060] See Figure 5 In this embodiment, the door shelf 300 may include a shelf body 310 and a limiting block 320. A storage groove 311 is provided on the upper side of the shelf body 310. The limiting block 320 protrudes from the bottom of the shelf body 310. A passageway 321 is provided within the limiting block 320 to support and limit the second magnetic component 410, allowing the door shelf 300 to be connected to the door body 200 via the second magnetic component 410, effectively improving the connection strength and reliability between the door shelf 300 and the door body 200. Furthermore, it facilitates the assembly and disassembly of the second magnetic component 140, improving the assembly and disassembly efficiency of the refrigeration device.

[0061] In some embodiments, a portion of the shelf body 310 is located between the two support ribs 210, and the shelf body 310 can fit against the door 200 and the two support ribs 210, so that the door 200 and the support ribs 210 can limit the movement of the door 200 in the left-right and rear directions, and can also improve the volume and space utilization of the shelf body 310.

[0062] In some embodiments, two limiting blocks 320 may be provided at the bottom of the shelf body 310. Two limiting holes are respectively provided on the left and right sides of the shelf body 310 to limit and support the two second magnetic components 410, so that the shelf body 310 can be connected to the door body 200 through the two second magnetic components 410, thereby improving the connection strength and reliability between the door body 200 and the door shelf 300.

[0063] In some embodiments, within the horizontal projection plane, the projection of the limiting block 320 is located within the area enclosed by the projection of the shelf body 310, so as to avoid external impacts on the limiting block 320 and affecting the connection strength between the limiting block 320 and the shelf body 310.

[0064] In other embodiments, the limiting block 320 can be integrally formed with the shelf body 310, or it can be bolted or snapped together, thereby ensuring the connection strength and reliability between the limiting block 320 and the shelf body 310.

[0065] Figure 8 This is a schematic diagram of the structure of the protective shell of this utility model.

[0066] See Figure 8In this embodiment, the door shelf 300 may further include a protective shell 330. The protective shell 330 is disposed at the bottom of the shelf body 310. The protective shell 330 and the shelf body 310 enclose a working space 340, which is used to accommodate the relevant control components of the second magnetic component 410 to protect the relevant control components and improve the stability and reliability of the refrigeration device.

[0067] In some embodiments, the protective shell 330 may have a notch relative to the limiting block 320. The protective shell 330 is located on the periphery of the limiting block 320, and the notch accommodates the limiting block 320, thereby reducing the volume of the limiting block 320 and the protective shell 330 and improving the space utilization of the door shelf 300. The passageway 321 is connected to the workspace 340, so that relevant components in the workspace 340 can be connected to the second magnetic element 410 to control the movement of the second magnetic element 410 within the passageway 321, thereby improving the operating efficiency of the second magnetic element 410.

[0068] In some embodiments, the limiting block 320 is fixedly connected to the shelf body 310, and the protective shell 330 is detachably connected to the shelf body 310, so that when the relevant control structure is disassembled and repaired, the shelf body 310 is limited to the door body 200 by the second magnetic element 410, so as to avoid the door shelf 300 supporting the goods when the relevant control components are repaired.

[0069] In other embodiments, the limiting block 320 can be connected to the protective shell 330, and both the limiting block 320 and the protective shell 330 can be detachably connected to the shelf body 310, so that when the door shelf 300 is being repaired, the limiting block 320, the protective shell 330 and their related control structures can be separated from the shelf body 310, thereby facilitating the repair of the related control structures and improving the repair efficiency of the refrigeration device.

[0070] See Figure 8 In this embodiment, the protective shell 330 is provided with a control groove 331 for the relevant control structure to extend out of the protective shell 330 for user operation. In some embodiments, the peripheral sidewall of the control groove 331 can abut against part of the relevant control structure to limit the adjustment stroke of the relevant control structure.

[0071] In some embodiments, within the horizontal projection plane, the projection of the protective shell 330 is located within the area enclosed by the projection of the shelf body 310, so as to avoid the protective shell 330 from bumping into the outside world and affecting the connection strength and reliability between the protective shell 330 and the shelf body 310.

[0072] See Figure 8In this embodiment, two limiting ribs 332 may be provided inside the protective shell 330. The two limiting ribs 332 are spaced apart along the extension direction of the passage channel 321 so that the two limiting ribs 332 can be located on opposite sides of the relevant control structure, thereby limiting the movement direction of the relevant control structure.

[0073] In some embodiments, the limiting ribs 332 may extend in the front-back direction and be spaced apart in the left-right direction to partially limit the movement direction of the related control structure.

[0074] See Figure 5 and Figure 6 In this embodiment, there can be two protective shells 330. The two protective shells 330 are spaced apart on the left and right sides of the shelf body 310. The two protective shells 330 are respectively provided corresponding to the two limiting blocks 320, so that the two protective shells 330 can respectively enclose the shelf body 310 to form two working spaces 340, and the two working spaces 340 are respectively used to accommodate and protect the relevant control structure.

[0075] Figure 9 This is a top view of the adjustment component and the second magnetic component of this utility model. Figure 10 yes Figure 9 The diagram shows a top view of the structure after the adjusting component of the shown structure has been rotated.

[0076] See Figure 9 and Figure 10 In this embodiment, the refrigeration device may further include an adjustment component 500. The adjustment component 500 is the aforementioned control structure. The adjustment component 500 is connected to the bottom of the door shelf 300. The adjustment component 500 is located within the working space 340, so as to apply a force away from the first magnetic component 230 to the second magnetic component 410, thereby causing the second magnetic component 410 to disengage from the engaging slot 220.

[0077] When the door shelf 300 is adjusted up and down to the preset position, the passageway 321 is arranged opposite to any of the locking slots 220, and the second magnetic element 410 can extend into the locking slot 220 under the magnetic force of the first magnetic element 230 to limit the door shelf 300 to the door body 200.

[0078] The adjustment component 500 can drive the second magnetic element 410 away from the first magnetic element 230 and disengage the second magnetic element 410 from the engagement groove 220 to adjust the vertical position of the door shelf 300.

[0079] See Figure 9 and Figure 10In this embodiment, the adjustment assembly 500 may include an adjustment member 540 and a third magnetic member 510. The adjustment member 540 is connected to the third magnetic member 510 so as to move the third magnetic member 510 closer to or further away from the port of the passage channel 321 away from the engaging slot 220. The magnetic force between the third magnetic member 510 and the second magnetic member 410 is greater than the magnetic force between the second magnetic member 410 and the first magnetic member 230.

[0080] When the third magnetic component 510 approaches the port of the passageway 321, the second magnetic component 410 separates from the first magnetic component 230 under the magnetic force of the third magnetic component 510 and disengages from the engaging groove 220, thereby enabling the door shelf 300 to adjust its position in the vertical direction.

[0081] When the third magnetic component 510 moves away from the port of the passageway 321, the third magnetic component 510 moves away from the second magnetic component 410. Under the magnetic force of the first magnetic component 230, the second magnetic component 410 moves toward the first magnetic component 230 and extends into the engaging groove 220, thereby limiting the door shelf 300 to different heights, so that the door shelf 300 can place items of different heights and improve the versatility of the refrigeration device.

[0082] See Figure 9 and Figure 10 In this embodiment, the third magnetic element 510 can extend in the front-back direction and can move in the front-back direction. When the third magnetic element 510 moves closer to the passageway 321, the second magnetic element 410 disengages from the engaging groove 220 under the magnetic force of the third magnetic element 510. When the third magnetic element 510 moves away from the passageway 321, the limiting block 320 can limit the movement of the second magnetic element 410 in the front-back direction, so that the third magnetic element 510 moves away from the second magnetic element 410. Under the magnetic force of the first magnetic element 230, the second magnetic element 410 moves within the passageway 321 and extends into the engaging groove 220, thereby ensuring the stable and reliable adjustment of the door shelf 300.

[0083] In some embodiments, the third magnetic element 510 may be disposed between the two limiting ribs 332, which limit the movement direction of the third magnetic element 510, so that the third magnetic element 510 can only move in the front-back direction, thereby moving closer to or away from the port of the passage channel 321 away from the first magnetic element 230.

[0084] In some embodiments, the third magnetic element 510 may be made of neodymium iron boron magnet, ferrite magnet or samarium cobalt magnet.

[0085] In this embodiment, one end of the adjusting member 540 can be connected to the third magnetic member 510, and the other end of the adjusting member 540 can extend out of the protective shell 330 through the control slot 331, so that the user can control the third magnetic member 510 through the adjusting member 540.

[0086] See Figure 9 and Figure 10 In this embodiment, the adjusting member 540 is rotatably connected to the protective shell 330 or the shelf body 310. In the left-right direction, the adjusting member 540 is located on one side of the third magnetic member 510. An arc-shaped gear portion 541 may be provided at one end of the adjusting member 540 near the third magnetic member 510. The gear portion 541 can mesh and drive the third magnetic member 510, so that when the adjusting member 540 rotates, it can drive the third magnetic member 510 to move in the front-back direction, thereby allowing the third magnetic member 510 to move closer to or further away from the end of the passageway 321.

[0087] In some embodiments, the rotation axis 550 of the adjustment member 540 can extend in the vertical direction so that the adjustment member 540 can rotate in the front-back direction. By conforming to the physiological structure and natural movement trajectory of the hand, and in accordance with the ergonomic design principles, the ease of operation and comfort of use are significantly improved.

[0088] In other embodiments, the adjusting member 540 may not be rotatably connected to the protective shell 330 or the shelf body 310. The adjusting member 540 may be disposed on the periphery of the adjusting member 540 and engaged, bolted, or tenoned with the third magnetic member 510. The adjusting member 540 can move back and forth to drive the third magnetic member 510 to move back and forth, thereby allowing the third magnetic member 510 to move closer to or further away from the end of the passageway 321.

[0089] In other embodiments, the adjusting member 540 can abut against the inner wall of the control groove 331 during rotation or movement, so that the protective shell 330 can limit the rotation angle or movement stroke of the adjusting member 540 through the control groove 331, thereby limiting the movement stroke of the third magnetic member 510, ensuring the cooperation relationship between the third magnetic member 510 and the second magnetic member 410, and improving the reliability and stability of the refrigeration device.

[0090] Figure 11 This is a structural schematic diagram of the movable column and the third magnetic component of this utility model.

[0091] See Figure 9 , Figure 10 and Figure 11In this embodiment, the adjusting assembly 500 may further include a movable column 520. The movable column 520 is located within the working space 340. The movable column 520 is movably connected to the bottom of the door shelf 300. The moving direction of the movable column 520 is perpendicular to the extending direction of the passageway 321. The movable column 520 has an embedding groove 521 for accommodating and limiting the third magnetic element 510. The adjusting member 540 is drively connected to the movable column 520, and the adjusting member 540 can drive the movable column 520 to move, thereby moving the third magnetic element 510 closer to or away from the port of the passageway 321.

[0092] When the adjusting component 500 adjusts the position of the third magnetic element 510, the adjusting component 540 adjusts the moving column 520 to move it in the front-back direction. The movement of the moving column 520 causes the third magnetic element 510, housed in the embedding slot 521, to move in the front-back direction, thereby moving it closer to or further away from the port of the passageway 321 away from the first magnetic element 230. Furthermore, the third magnetic element 510 is embedded in the moving column 520, allowing the protective column to protect the third magnetic element 510 from impacts and collisions during use and maintenance.

[0093] In some embodiments, in the left-right direction, the embedding slot 521 is disposed on the side of the movable column 520 facing the passage channel 321. When the movable column 520 approaches the passage channel 321, the position of the embedding slot 521 ensures that there is no obstruction between the third magnetic element 510 and the second magnetic element 410, thereby avoiding affecting the magnetic force transmission effect between the third magnetic element 510 and the second magnetic element 410, and ensuring the reliability and stability of the magnetic connection between the third magnetic element 510 and the second magnetic element 410.

[0094] See 6, and Figure 7 In this embodiment, the extending direction of the limiting rib 332 is the same as the moving direction of the moving column 520. The moving column 520 is located between the two limiting ribs 332 so that the two limiting ribs 332 can respectively abut against the left and right sides of the moving column 520, thereby limiting the moving column 520 to move only in the front-back direction, ensuring the stability and reliability of the moving column 520 during the movement process.

[0095] See Figure 9 and Figure 10In this embodiment, a rack portion 522 protrudes from the side of the movable column 520 away from the passage channel 321 in the left-right direction. That is, the rack portion 522 and the insertion groove 521 are located on opposite sides of the movable column 520. The rack portion 522 extends parallel to the moving direction of the movable column 520, extending in the front-back direction. The rack portion 522 can mesh with the gear portion 541 of the adjusting member 540, so that when the adjusting member 540 rotates, it can drive the movable column 520 to move in the front-back direction through the gear portion 541 and the rack portion 522. This allows the third magnetic member 510 to approach or move away from the port of the passage channel 321, and allows the second magnetic member 410 to extend into or disengage from the engaging groove 220, ensuring the stability and reliability of the adjusting assembly 500, reducing the travel of the adjusting assembly 500, and improving the space utilization of the adjusting assembly 500.

[0096] In some embodiments, the rack portion 522 is spaced apart from the lower surface of the moving column 520 in the vertical direction, so that both the left and right side walls of the moving column 520 can abut against the two limiting ribs 332. The rack portion 522 is located above the limiting ribs 332 to avoid the limiting ribs 332 affecting the meshing transmission between the rack portion 522 and the adjusting member 540, thereby ensuring the reliability and stability of the adjusting assembly 500.

[0097] In other embodiments, the limiting rib 332 and the limiting block 320 are spaced apart in the front-back direction to avoid the limiting rib 332 affecting the magnetic force transmission effect between the third magnetic element 510 and the second magnetic element 410.

[0098] In other embodiments, both the shelf body 310 and the protective shell 330 are provided with two limiting ribs 332. In the vertical direction, the rack portion 522 and the upper and lower surfaces of the moving column 520 are spaced apart, so that the left and right side walls of the upper part of the moving column 520 abut against the two limiting ribs 332 on the shelf body 310, and the left and right side walls of the lower part of the moving column 520 abut against the two limiting ribs 332 on the protective shell 330, so that the limiting ribs 332 on the shelf body and the protective shell 330 together limit the moving column 520, thereby ensuring the stability and reliability of the movement of the limiting column.

[0099] In other embodiments, the upper and lower sidewalls of the rack portion 522 can respectively abut against the limiting ribs 332 on the shelf body 310 and the protective shell 330, so as to limit the up and down jumping of the moving column 520 and ensure the stability and reliability of the adjustment component 500.

[0100] In other embodiments, the limiting rib 332 may be provided only on the shelf body 310 to limit the movement direction of the movable column 520.

[0101] See Figure 9 and Figure 10In this embodiment, the adjusting assembly 500 may further include at least one transmission gear 530. The transmission gear 530 is disposed between the moving column 520 and the adjusting member 540. The rotation axis 550 of the transmission gear 530 is parallel to the rotation axis 550 of the adjusting member 540. The transmission gear 530 meshes with the rack portion 522 of the moving column 520 and the gear portion 541 of the adjusting member 540 respectively, to realize the transmission connection between the moving column 520 and the adjusting member 540.

[0102] In some embodiments, the adjusting assembly 500 may include two transmission gears 530. The two transmission gears 530 mesh with each other, and one transmission gear 530 meshes with a gear portion 541 on the adjusting member 540, while the other transmission gear 530 meshes with a rack portion 522 of the moving column 520, so as to change the rotation direction of the adjusting member 540, thereby facilitating the user's hand to apply force to the adjusting member 540 and improving the operating efficiency of the adjusting assembly 500.

[0103] In other embodiments, the number of teeth of the transmission gear 530 meshing with the adjusting member 540 is less than the number of teeth of the transmission gear 530 meshing with the moving column 520, so as to amplify the torque, ensure the reliability of the moving column 520 during movement, and improve the stability of the adjusting assembly 500.

[0104] See Figure 9 and Figure 10 In this embodiment, the adjustment assembly 500 may further include multiple rotating shafts 550. The rotating shafts 550 are engaged within the working space 340, and the multiple rotating shafts 550 may respectively pass through the transmission gear 530 and the adjusting member 540 to support the rotation of the transmission gear 530 and the adjusting member 540.

[0105] In some embodiments, the rotation axis 550 line of the rotating shaft 550 can be perpendicular to the moving direction of the second magnetic element 410 and the moving direction of the third magnetic element 510, so that when the adjusting member 540 and the transmission gear 530 rotate, they can drive the moving column 520 to move and drive the third magnetic element 510 to move closer to or away from the passageway 321.

[0106] In other embodiments, the rotating shaft 550 may extend in the vertical direction so that both ends of the rotating shaft 550 are rotatably engaged within the shelf body and the protective shell 330, thereby ensuring the stability and reliability of the adjustment assembly 500.

[0107] In other embodiments, the rotating shaft 550 may be integrally formed with the transmission gear 530 and the adjusting member 540.

[0108] See Figure 9 and Figure 10In this embodiment, the adjusting assembly 500 may further include an elastic element 560. The elastic element 560 is located between the adjusting member 540 and the protective shell 330. The elastic element 560 can apply an elastic force to the adjusting member 540, causing the adjusting member 540 to drive the moving column 520 away from the passage channel 321 via the transmission gear 530. This separates the third magnetic element 510 from the second magnetic element 410, preventing the third magnetic element 510 from exerting a magnetic influence on the second magnetic element 410. Furthermore, this effectively improves the automation level of the adjusting assembly 500, enhancing the efficiency and ease of use of the refrigeration device.

[0109] In some embodiments, the elastic element 560 can be a torsion spring. The torsion spring is sleeved on the rotation shaft 550 where the adjusting element 540 is located, and one end of the torsion spring is connected to the adjusting element 540, and the other end of the torsion spring is connected to the protective shell 330 or the shelf body, so as to absorb the kinetic energy when the adjusting element 540 rotates and to apply an elastic force to the adjusting element 540.

[0110] See Figure 6 and Figure 7 In this embodiment, the refrigeration device may further include two adjusting components 500. The two adjusting components 500 are respectively housed within two working spaces 340. The two adjusting components 500 are symmetrically arranged in the left-right direction so that the two adjusting components 500 can be magnetically connected to the two second magnetic elements 410 respectively, thereby enabling the two second magnetic elements 410 to be disengaged from the engaging slots 220, facilitating user operation and use.

[0111] See Figures 1 to 11 This application provides a refrigeration device. When the refrigeration device is in use, the user can apply a forward force to the end of the adjusting member 540 away from the transmission gear 530 to rotate the adjusting member 540. As the adjusting member 540 rotates, the elastic member 560 elastically contracts. The adjusting member 540 can drive the moving column 520 to move rearward toward the passageway 321 via the gear portion 541, the transmission gear 530, and the rack portion 522. The moving column 520 drives the third magnetic member 510 to move rearward, so that the third magnetic member 510 is opposite to the second magnetic member 410. At this time, under the action of the third magnetic member 510, the second magnetic member 410 moves away from the first magnetic member 230 and disengages from the engaging groove 220, so that the third magnetic member 510 and the second magnetic member 410 are magnetically connected.

[0112] After the second magnetic component 410 disengages from the engaging slot 220, the user can move the door shelf 300 to adjust its vertical position, thereby enabling the door shelf 300 to accommodate items of different heights, increasing the applicability of the door shelf 300 and improving the user experience of the refrigeration device.

[0113] After the door shelf 300 moves to the preset position, the user releases the adjusting member 540. The adjusting member 540 rotates backward under the action of the elastic member 560, driving the moving column 520 forward via the transmission gear 530. The moving column 520 moves forward, causing the third magnetic member 510 to move away from the passageway 321 and separate from the second magnetic member 410. At this time, the second magnetic member 410, under the action of the first magnetic member 230, extends into the engaging groove 220, thus limiting the door shelf 300 to the door body 200, effectively improving the efficiency of adjusting the position of the door shelf 300 and facilitating user operation.

[0114] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.
