Description

Technical Field

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

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, a refrigerator has a refrigeration compartment that creates a refrigerated environment for storing items. Generally, the refrigeration compartment can be used to store fresh ingredients, frozen foods, or various other goods.

[0003] As living spaces, especially kitchen spaces, become increasingly compact, the effective use of their interior space becomes particularly important.

[0004] Currently, by setting up multiple shelves in the refrigeration compartment, which can be spaced vertically, the refrigeration compartment can be divided into multiple spaces, thus improving the utilization of the refrigeration compartment. However, this cannot adapt to the differences in the various foods stored by users and their usage habits. For example, the spaced shelves are not fully utilized, or the spacing between shelves is not suitable when storing tall items. The utilization rate of the refrigeration compartment in the refrigerator needs to be further improved and enhanced. Summary of the Invention

[0005] The purpose of this invention is to provide a refrigeration device that allows for flexible arrangement of baskets within a refrigeration room, thereby improving the space utilization rate of the refrigeration room.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; a liner disposed within the housing, the liner having a refrigeration chamber; a shelf disposed within the refrigeration chamber; a first storage rack slidably connected to the lower part of the shelf, the first storage rack forming a first storage space between itself and the bottom surface of the shelf; and a second storage rack connected to the lower part of the shelf and disposed on one side of the first storage rack, the second storage rack forming a second storage space between itself and the bottom surface of the shelf; wherein the first storage rack includes a first sidewall extending along the refrigeration device. The shelf extends vertically, with the upper end of the first sidewall slidably connected to the shelf; a first bottom wall is spaced below the shelf, with one horizontal end of the first bottom wall connected to the lower end of the first sidewall, and the other horizontal end of the first bottom wall movably positioned below the second storage rack; a first storage space is formed between the bottom surface of the shelf, the first sidewall, the first bottom wall, and the outer sidewall of the second storage rack; the first sidewall can move along the length of the shelf toward or away from the second storage rack to reduce or increase the volume of the first storage space.

[0008] The above technical solution has the following advantages or beneficial effects: A first storage rack and a second storage rack are installed below the shelf, with the second storage rack located on one side of the first storage rack. The first and second storage racks, together with the bottom surface of the shelf, form a first storage space and a second storage space, respectively. This increases the storage space hierarchy within the refrigeration room, effectively utilizing the space that might otherwise be wasted below the shelf. Furthermore, the creation of different storage spaces can further meet users' needs for categorizing and storing different foods or items. For example, small items, easily rolling items, or items requiring separate storage can be placed in the storage space, making the arrangement of items in the refrigeration room more orderly. Further, the first sidewall can move along the length of the shelf towards or away from the second storage rack, and the other end of the first bottom wall is movably located below the second storage rack. This allows the volume of the first storage space to be flexibly adjusted according to actual needs. When it is necessary to store larger or more items in the first storage space, the first sidewall can be moved away from the second storage rack, thereby increasing the volume of the first storage space. When storing small items that don't require much storage space, or when the space under the shelves needs to accommodate taller items, the first sidewall can be moved closer to the second storage shelf, reducing the volume of the first storage space. The arrangement of the first and second storage shelves will not completely occupy the width of the space under the shelves, thus freeing up space for taller items. By allowing the first storage shelf to move relative to the second, the storage space can be flexibly adjusted, enhancing the adaptability of the refrigeration unit to different storage scenarios and user habits. This results in more rational storage of items inside the refrigerator, improving the user experience.

[0009] In some embodiments of this application, a refrigeration device is provided, wherein a first sliding portion is provided on each of the opposite sides of the top of the first sidewall, and the two first sliding portions are slidably connected to the opposite side edges of the shelf.

[0010] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by setting the first sliding part on the opposite sides of the top of the first side wall and sliding it to the opposite sides of the shelf, the first storage rack can slide stably along the entire horizontal length of the shelf, thereby making fuller use of the horizontal space under the shelf from one side to the other. In this way, whether adjusting the first storage space to accommodate longer items or flexibly changing the spatial layout according to the storage needs of the items, the space in the horizontal direction of the refrigeration room can be effectively utilized, further improving the overall space utilization rate of the refrigeration room.

[0011] In some embodiments of this application, a cooling device is provided, wherein the first storage rack includes a second sidewall, the second sidewall is disposed at the end of the first bottom wall away from the first sidewall, and the second sidewall is slidably connected to the second storage rack.

[0012] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: In order to further increase the stability and reliability of the first storage rack in the refrigeration room, by sliding the second side wall to the second storage rack, when the first side wall moves along the length of the shelf toward or away from the second storage rack, the opposite sides of the first bottom wall can respectively form a sliding connection with the shelf and the second storage rack. This can disperse the stress generated during the sliding process, reduce the wear and damage of the sliding parts on one side, and facilitate the smoothness and accuracy of the first storage rack when adjusting the space, avoiding structural jamming or damage caused by poor sliding.

[0013] In some embodiments of this application, a cooling device is provided, wherein the first storage rack includes a second sliding portion, the second sliding portion being respectively disposed on opposite sides of the top of the second sidewall, and the two second sliding portions being slidably connected to the opposite side edges of the second storage rack.

[0014] Another technical solution described above has the following advantages or beneficial effects: By providing second sliding parts on opposite sides of the top of the second sidewall and slidably connecting them to the opposite side edges of the second storage rack, the first storage rack can slide not only along the shelf direction via the first sidewall but also along the second storage rack direction via the second sidewall when adjusting the first storage space. This improves the stability of the sliding process of the first storage rack, allowing users to more accurately adjust the volume and shape of the first storage space according to the specific size and shape of the items to be stored. Furthermore, the sliding connection between the second sliding parts and the edges of the second storage rack adds additional support connection points to the first storage rack, effectively dispersing the force exerted on the first storage rack when carrying items and reducing the concentration of force on individual components.

[0015] In some embodiments of this application, a refrigeration device is provided, wherein the second storage rack includes a second bottom wall, spaced apart below the shelf; a third side wall, extending along the height direction of the refrigeration device, the upper end of the third side wall being connected to the shelf, and the lower end of the third side wall being connected to the end of the second bottom wall near the first side wall; a first accommodating space is formed between the bottom surface of the shelf, the first side wall, the first bottom wall, and the third side wall; a second accommodating space is formed between the bottom surface of the shelf, the third side wall, and the second bottom wall; and two second sliding portions are slidably connected to opposite side edges of the second bottom wall.

[0016] Another technical solution described above has the following advantages or beneficial effects: the first storage space is located on one side of the third side wall, and the second storage space is located on the other side of the third side wall. The third side wall divides the space below the shelf, thus forming a horizontally adjacent first storage space and a second storage space. In this way, the first and second storage shelves can subdivide the storage area below the shelf, allowing users to classify and store items in different storage spaces according to their size, shape, and frequency of use. This facilitates full utilization of the vertical space within the refrigeration room and greatly improves space utilization.

[0017] In some embodiments of this application, a refrigeration device is provided, wherein the second storage rack further includes a fourth side wall, the fourth side wall and the third side wall are respectively disposed on the lateral ends of the second bottom wall, the fourth side wall extends along the height direction of the refrigeration device, the lower end of the fourth side wall is connected to the second bottom wall, and the upper end of the fourth side wall is connected to the shelf; the second accommodating space is formed between the bottom surface of the shelf, the third side wall, the second bottom wall and the fourth side wall.

[0018] Another technical solution described above has the following advantages or beneficial effects: the bottom surface, third side wall, second bottom wall, and fourth side wall of the shelf can form a relatively closed U-shaped structure. This makes the second storage space a relatively regular, enclosed area, making it easier for users to classify and organize items, thus improving the orderly use of space. Furthermore, the upper end of the fourth side wall is connected to the shelf, and the lower end is connected to the second bottom wall, allowing the opposite sides of the second bottom wall to be connected to the shelf via the third and fourth side walls respectively, forming a stable frame structure. This facilitates a more stable and reliable placement of the second storage rack within the refrigeration room.

[0019] In some embodiments of this application, a refrigeration device is provided, wherein the upper end of the third sidewall is slidably connected to the shelf, and the upper end of the fourth sidewall is slidably connected to the shelf.

[0020] Another technical solution described above has the following advantages or beneficial effects: the second storage rack can move along the length of the shelf, and thus perform lateral extension and retraction adjustments in the horizontal direction to adjust the position distribution of the second storage rack within the cooling space. In this way, the user can not only adjust the volume of the first storage space by moving the first storage rack, but also adjust the volume of the first storage space by moving the second storage rack so that it can slide relative to the first storage rack.

[0021] In some embodiments of this application, a cooling device is provided, wherein the second storage rack includes a third sliding portion, the third sliding portion extending along the length direction of the shelf, one lateral end of the third sliding portion being connected to the third side wall, and the other lateral end of the third sliding portion being connected to the fourth side wall, and the third sliding portion being slidably connected to the shelf.

[0022] Another technical solution described above has the following advantages or beneficial effects: By setting a third sliding part connected to the top of the third side wall and the top of the fourth side wall, and simultaneously slidingly connected to the shelf, the third sliding part can synchronously drive the third and fourth side walls to move within the refrigeration room during the sliding process relative to the shelf. This allows the second storage rack to move stably and reliably relative to the shelf, thereby adjusting the position of the second storage rack within the refrigeration room. Furthermore, the third sliding part, supported and connected between the third and fourth side walls, can improve the overall structural strength of the second storage rack, reduce swaying and offset during sliding, and reduce wear and friction between the sliding components.

[0023] In some embodiments of this application, a refrigeration device is provided, wherein the third sliding part includes two parts, one of which is disposed between one side of the top of the third sidewall and the fourth sidewall, and the other of which is disposed between the other side of the top of the third sidewall and the fourth sidewall, and the two third sliding parts are slidably connected to the opposite two sides of the shelf.

[0024] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the two third sliding parts are respectively connected to the opposite sides of the top of the third side wall and the fourth side wall, and are respectively slidably connected to the opposite sides of the shelf, so that the second storage rack forms a bidirectional sliding connection structure with the shelf. During the sliding process, the two third sliding parts can be subjected to force and work together at the same time, and can more evenly distribute the friction and gravity generated when the side wall moves. This not only makes the sliding operation easy and effortless, but also allows the third side wall, the fourth side wall and the second bottom wall to maintain a stable state during the sliding process, avoiding problems such as side wall tilting and jamming caused by uneven force on one side.

[0025] In some embodiments of this application, a refrigeration device is provided, wherein a third sidewall is provided with a first support rib on one side of the first storage space, and the first support rib is spaced apart above the second bottom wall; a fourth sidewall is provided with a second support rib on one side of the first storage space, and the second support rib is spaced apart above the second bottom wall; the refrigeration device includes a support plate, the support plate is disposed in the first storage space, and the bottom of the support plate on opposite sides is respectively supported on the top surfaces of the first support rib and the second support rib.

[0026] Another technical solution described above has the following advantages or beneficial effects: the first and second support ribs are spaced apart above the second bottom wall, providing a stable support structure for the support plate. This allows the support plate to evenly distribute the weight of the items onto the third side wall, the fourth side wall, and the second bottom wall, enhancing the structural load-bearing capacity of the entire second storage rack. Furthermore, by installing the support plate within the first storage space, the support plate can divide the first storage space into two vertically arranged storage spaces, thereby achieving multi-level layered storage within the first storage space. This facilitates full utilization of the height space of the first storage space and increases the overall storage capacity. Attached Figure Description

[0050] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator, or other refrigeration cabinet. The following uses a refrigerator as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0051] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0052] like Figure 1 As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigeration device. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0053] Figure 2 for Figure 1A schematic diagram of the first state.

[0054] like Figure 2 As shown, in some embodiments, a refrigeration chamber 201 can be formed inside the housing 1. Multiple refrigeration chambers 201 can be provided.

[0055] In some embodiments, the refrigeration device may include a liner 2. The liner 2 may be disposed inside the housing 1. A refrigeration chamber 201 may be provided inside the liner 2. A foaming space is formed between the liner 2 and the housing 1. When foaming material is filled into the foaming space, it can effectively insulate the refrigeration chamber 201.

[0056] like Figure 1 As shown, in some embodiments, the refrigeration device may include a door 11. The door 11 is disposed on the top front side of the housing 1 and covers the front opening of the refrigeration compartment 201 for opening and closing the refrigeration compartment 201.

[0057] In some embodiments, the refrigeration device may include a door 11. The door 11 is disposed on the top front side of the housing 1 and covers the top opening of the refrigeration compartment 201 for opening and closing the refrigeration compartment 201.

[0058] In some embodiments, the refrigeration device may include a refrigeration system. The refrigeration system may be located inside the cabinet 1. The refrigeration system is used to provide cold air to the interior of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 201.

[0059] In some embodiments, the refrigeration system includes a compressor (not shown). The compressor, as the power source of the refrigeration cycle, draws in low-temperature, low-pressure refrigerant gas and compresses it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0060] In some embodiments, the refrigeration system includes a condenser, which may be located within the compressor chamber. The condenser receives refrigerant flowing from the compressor, cools the high-temperature, high-pressure refrigerant gas from the compressor, and converts it into a liquid state. The condenser can transfer heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0061] In some embodiments, the refrigeration system includes a throttling device (not shown). The condenser can deliver the condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0062] In some embodiments, the refrigeration system includes an evaporator (not shown). A throttling device can deliver a throttled and depressurized refrigerant into the evaporator. The evaporator can be used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0063] In some embodiments, the compressor, condenser, throttling device, and evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the refrigeration chamber 201.

[0064] like Figure 2 As shown, in some embodiments, the refrigeration device includes shelves 3 disposed within the refrigeration chamber 201. The top surface of the shelves 3 is used to support items to be refrigerated. Multiple shelves 3 may be provided, spaced apart along the height of the display case within the refrigeration chamber 201, thereby dividing the refrigeration chamber 201 into multiple storage spaces.

[0065] Figure 3 for Figure 2 A schematic diagram of the first storage rack after it has been moved.

[0066] like Figure 2 and Figure 3 As shown, in some embodiments, the refrigeration device includes a first storage rack 4, which is slidably connected to the lower part of the shelf 3. The first storage rack 4 can slide relative to the shelf 3 and then slide along the length of the shelf 3 to change the position of the first storage rack 4 in the refrigeration room.

[0067] A first storage space 401 is formed between the bottom surface of the first storage rack 4 and the shelf 3. The first storage space 401 can be used to place items to be refrigerated. By placing the first storage rack 4 below the shelf 3, the storage space below the shelf 3 can be increased.

[0068] In some embodiments, the refrigeration device includes a second storage rack 5, which can be connected to the lower part of the shelf 3 and disposed on one side of the first storage rack 4. The second storage rack 5 and the first storage rack 4 can be arranged adjacent to each other along the left-right direction of the refrigeration chamber 201. The second storage rack 5 has a second storage space 501, which can be disposed on one side of the first storage space 401. The second storage space 501 can be used to place items to be refrigerated, and the second storage space 501 is formed between the bottom surface of the second storage rack 5 and the shelf 3. By placing the second storage rack 5 below the shelf 3 and arranging it adjacent to the first storage rack 4, the storage space hierarchy below the shelf 3 is further increased.

[0069] The first storage rack 4 includes a first side wall 41 and a first bottom wall 42. The first side wall 41 extends along the height direction of the refrigeration device, and the upper end of the first side wall 41 can extend upward to the shelf 3, and the upper end of the first side wall 41 is slidably connected to the shelf 3.

[0070] The first bottom wall 42 is spaced below the shelf 3. The first bottom wall 42 can extend laterally along the refrigeration compartment 201 and can be arranged parallel to the shelf 3. One lateral end of the first bottom wall 42 is connected to the lower end of the first side wall 41, and the other lateral end of the first bottom wall 42 is movably located below the second storage rack 5. The first side wall 41 and the first bottom wall 42 can form an L-shaped structure.

[0071] The first storage space 401 is formed between the bottom surface of the shelf 3, the first side wall 41, the first bottom wall 42, and the outer side wall of the second storage shelf 5. The first side wall 41 can move along the length of the shelf 3 toward or away from the second storage shelf 5 to reduce or increase the volume of the first storage space 401.

[0072] Specifically, the first sidewall 41 extends along the height of the refrigeration unit, with its upper end slidably connected to the shelf 3. One end of the first bottom wall 42 is connected laterally to the lower end of the first sidewall 41, and the other end is movably positioned below the second storage rack 5. When the first sidewall 41 moves along the length of the shelf 3, the first bottom wall 42 can move relative to the second storage rack 5. During this process, the first sidewall 41 can move along the length of the shelf 3 towards or away from the second storage rack 5, thus changing the volume of the first storage space 401 formed between the bottom surface of the shelf 3, the first sidewall 41, the first bottom wall 42, and the outer sidewall of the second storage rack 5. This allows the volume of the first storage space 401 to be flexibly adjusted according to actual needs. Moving the first sidewall 41 away from the second storage rack 5 increases the volume of the first storage space 401, while moving it towards the second storage rack 5 decreases the volume of the first storage space 401.

[0073] As living spaces, especially kitchen spaces, become increasingly compact, the effective utilization of their internal space is particularly important. Currently, by setting multiple shelves 3 within the refrigeration compartment 201, which can be spaced vertically, the refrigeration compartment 201 is divided into multiple spaces, thus improving its utilization. However, this method cannot adapt to the differences in the various foods stored and usage habits of users. For example, the spaced shelves 3 are not fully utilized, or the spacing between shelves 3 is not suitable when storing tall items. Therefore, the utilization rate of the refrigeration compartment 201 inside the refrigerator needs further improvement.

[0074] In the technical solution of this application, a first storage rack 4 and a second storage rack 5 are provided below the shelf 3. The second storage rack 5 is located on one side of the first storage rack 4. The first storage rack 4 and the second storage rack 5 form a first storage space 401 and a second storage space 501 with the bottom surface of the shelf 3, respectively. This increases the storage space hierarchy in the refrigeration chamber 201, making effective use of the space that might have been wasted below the shelf 3. Moreover, the different storage spaces can further meet the user's needs for classifying and storing different food items or items. For example, small items, easily rolling items, or items that need to be stored separately can be placed in the storage space, making the items in the refrigeration chamber 201 more orderly.

[0075] Furthermore, the first side wall 41 of the first storage rack 4 extends along the height direction of the refrigeration device and is slidably connected to the shelf 3 at its upper end. One end of the first bottom wall 42 is connected to the lower end of the first side wall 41 in a horizontal direction, and the other end is movably located below the second storage rack 5. The first side wall 41 can move along the length direction of the shelf 3 toward or away from the second storage rack 5, and the other end of the first bottom wall 42 is movably located below the second storage rack 5 in a horizontal direction. This allows the volume of the first storage space 401 to be flexibly adjusted according to actual needs. When it is necessary to store larger or more items in the first storage space 401, the first side wall 41 can be moved away from the second storage rack 5, thereby increasing the volume of the first storage space 401. When storing small items that don't require much storage space, or when the space under shelf 3 needs to accommodate tall items, the first sidewall 41 can be moved closer to the second storage shelf 5, reducing the volume of the first storage space 401. The arrangement of the first and second storage shelves 4 and 5 will not completely occupy the width of the space under shelf 3, thus freeing up space for taller items. By allowing the first storage shelf 4 to move relative to the second storage shelf 5, the refrigerator can flexibly adjust its storage capacity, enhancing its adaptability to different storage scenarios and user habits. This results in more rational storage of items within the refrigerator, improving the user experience.

[0076] On the other hand, when storing or retrieving items, users can easily adjust the storage space by sliding the first storage rack 4 according to the size and storage location of the items, without having to perform complicated operations such as disassembling or reinstalling the shelf 3. The operation is simple and convenient, greatly improving the convenience of users using the refrigeration device.

[0077] In some embodiments, the first bottom wall 42 can be slidably connected to the bottom of the shelf 3 via support rods (not shown in the figure). The lower end of the support rod can be connected to the first bottom wall 42, and the upper end of the support rod can be slidably connected to the shelf 3. There can be four support rods, with two support rods located on opposite sides of the front end of the first bottom wall 42 and the other two support rods located on opposite sides of the rear end of the first bottom wall 42.

[0078] In some other embodiments, the first storage space 401 and the second storage space 501 can be connected, that is, there may be no separating sidewall between the first storage space 401 and the second storage space 501.

[0080] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, a first sliding portion 43 may be provided on each of the opposite sides of the top of the first sidewall 41, and the two first sliding portions 43 are slidably connected to the opposite side edges of the shelf 3. Specifically, one of the first sliding portions 43 is slidably connected to the front side of the shelf 3, and the other first sliding portion 43 is slidably connected to the rear side of the shelf 3.

[0081] By providing first sliding parts 43 on opposite sides of the top of the first side wall 41 and slidably connecting them to the opposite sides of the shelf 3, the first storage rack 4 can slide stably along the entire horizontal length of the shelf 3. This allows for more efficient use of the horizontal space below the shelf 3 from one side to the other. As a result, whether adjusting the first storage space 401 to accommodate longer items or flexibly changing the spatial layout according to the storage needs of the items, the space in the horizontal direction of the refrigeration room 201 can be effectively utilized, further improving the overall space utilization rate of the refrigeration room 201.

[0082] Furthermore, the two first sliding parts 43 are respectively connected to the opposite side edges of the shelf 3 to form a double-point supported sliding structure, which can effectively enhance the stability of the first storage rack 4 during the sliding process, and at the same time make it easier and less strenuous for users to adjust the first storage rack 4. When adjusting the volume of the first storage space 401, the first storage rack 4 is also less likely to shake, tilt or get stuck.

[0083] like Figure 5 and Figure 6As shown, in some embodiments, the first sliding part 43 may be provided with a first sliding groove 402. The first sliding groove 402 may have a certain length and the length of the first sliding groove 402 extends along the length direction of the shelf 3. The first sliding groove 402 located on the front side of the first sidewall 41 opens rearward and is slidably connected to the front side of the shelf 3, and the first sliding groove 402 located on the rear side of the first sidewall 41 opens forward and is slidably connected to the rear side of the shelf 3.

[0084] Figure 7 for Figure 4 A cross-sectional view.

[0085] like Figure 4 and Figure 7 As shown, in some embodiments, the shelf 3 may include a shelf panel 31 arranged laterally within the refrigeration compartment 201, and a front trim strip 32 and a rear trim strip 33 disposed on the front and rear sides of the shelf panel 31. A first groove 402 located on the front side of the first sidewall 41 can be slidably connected to the front trim strip 32, and a first groove 402 located on the rear side of the first sidewall 41 can be slidably connected to the rear trim strip 33. This simplifies the fit between the first storage rack 4 and the shelf 3, allowing the first storage rack 4 to be directly and slidably connected to other shelf panels 3 within the refrigeration compartment 201.

[0086] In some embodiments, a roller (not shown in the figure) or a ball bearing (not shown in the figure) may be movably disposed in the first chute 402. The roller is rotatably disposed between the chute wall of the first chute 402 and the shelf 3.

[0087] Because the first sliding part 43 is prone to frictional damage at the contact point between the shelf 3 and the first sliding part 43 during sliding, by setting rollers in the first sliding groove 402, the sliding friction between the groove wall of the first sliding groove 402 and the shelf 3 is transformed into rolling friction, making the movement of the shelf 3 within the first sliding groove 402 smoother. This avoids wear caused by frequent sliding friction between the groove wall of the first sliding groove 402 and the shelf 3 during long-term use of the first storage rack 4, which would increase the surface roughness of the components, affecting the smoothness of sliding and even potentially damaging the components, thus improving the durability of the first storage rack 4.

[0088] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the first storage rack 4 includes a second sidewall 44. The second sidewall 44 may be disposed at the end of the first bottom wall 42 away from the first sidewall 41, and the second sidewall 44 is slidably connected to the second storage rack 5.

[0089] The second sidewall 44 can extend along the height of the refrigeration chamber 201. The lower end of the second sidewall 44 is connected to the first bottom wall 42, and the upper end of the second sidewall 44 can extend to the bottom of the second storage rack 5. The height difference between the first bottom wall 42 and the second storage rack 5 can correspond to the height of the second sidewall 44. The first sidewall 41 and the second sidewall 44 can be arranged opposite each other on both sides of the first bottom wall 42.

[0090] To further enhance the stability and reliability of the first storage rack 4 in the refrigeration room 201, the second side wall 44 is slidably connected to the second storage rack 5. When the first side wall 41 moves along the length of the shelf 3 toward or away from the second storage rack 5, the opposite sides of the first bottom wall 42 can form a sliding connection with the shelf 3 and the second storage rack 5 respectively. This can disperse the stress generated during the sliding process, reduce wear and damage to the sliding parts on one side, and facilitate the smoothness and accuracy of the first storage rack 4 when adjusting the space, avoiding structural jamming or damage caused by poor sliding.

[0091] On the other hand, when items are placed inside the first storage rack 4, the first side wall 41 is slidably connected to the shelf 3 and the second side wall 44 is slidably connected to the second storage rack 5, making the first storage rack 4 more stable when bearing the weight of the items. When items are placed inside the first storage space 401, the first side wall 41 and the second side wall 44 can provide certain support and limit the items, preventing them from falling due to shaking or collision, thus improving the structural stability and safety of the first storage rack 4.

[0092] In some other embodiments, the second sidewall 44 may be slidably connected to the shelf 3.

[0093] Figure 8 for Figure 4 Another cross-sectional view.

[0094] like Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments, the first storage rack 4 may include a second sliding portion 45, which is respectively disposed on opposite sides of the top of the second sidewall 44, and the two second sliding portions 45 are slidably connected to opposite side edges of the second storage rack 5. Specifically, one second sliding portion 45 is slidably connected to the front side of the shelf 3, and the other second sliding portion 45 is slidably connected to the rear side of the shelf 3.

[0095] Specifically, by providing second sliding parts 45 on opposite sides of the top of the second sidewall 44 and slidably connecting them to the opposite side edges of the second storage rack 5, the first storage rack 4 can slide not only in the direction of the shelf 3 via the first sidewall 41, but also in the direction of the second storage rack 5 via the second sidewall 44 when adjusting the first storage space 401. This helps to improve the stability of the sliding process of the first storage rack 4, and allows users to more accurately adjust the volume and shape of the first storage space 401 according to the specific size and shape of the items to be stored.

[0096] Furthermore, the sliding connection between the second sliding part 45 and the edge of the second storage rack 5 provides an additional support connection point for the first storage rack 4. On the one hand, this effectively disperses the force on the first storage rack 4 when carrying items, reducing the concentration of force on individual components, thereby enhancing the overall structural stability of the first storage rack 4 and enabling it to withstand heavier items without easily deforming or being damaged. On the other hand, it allows the first storage rack 4 to better maintain the balance and stability of the second sidewall 44 during sliding, reducing the occurrence of wobbling and jamming of the first storage rack 4.

[0097] In some embodiments, the second sliding portion 45 may be provided with a second sliding groove 403, which may have a certain length and the length of the second sliding groove 403 extends along the length direction of the shelf 3. The second sliding groove 403 located on the front side of the second sidewall 44 opens rearward and is slidably connected to the front side of the shelf 3, while the first sliding groove 402 located on the rear side of the first sidewall 41 opens forward and is slidably connected to the rear side of the shelf 3.

[0098] like Figure 5 and Figure 6 As shown, in some embodiments, the first storage rack 4 may include a first support plate 410, a first side plate 420, and a second side plate 430. The first side plate 420 and the second side plate 430 may be respectively disposed on opposite sides of the first support plate 410. The top surface of the first support plate 410 is provided with a first bottom wall 42, the first side plate 420 is provided with a first side wall 41, and the second side plate 430 is provided with a second side wall 44. The first support plate 410, the first side plate 420, the shelf 3, and the outer sides of the second storage rack 5 can enclose to form a first storage space 401.

[0099] The first support plate 410 can move relative to the second storage rack 5, thereby adjusting the volume of the first storage space 401.

[0100] The first sliding part 43 can be integrally formed with the first side plate 420, and the second sliding part 45 can be integrally formed with the second side plate 430. The first support plate 410 is detachably disposed between the first side plate 420 and the second side plate 430.

[0101] It should be noted that in some embodiments, the first storage rack 4 may also be a basket-shaped structure, with a first bottom wall 42 formed at the bottom of the first storage rack 4, and a first side wall 41 and a second side wall 44 formed on opposite sides of the first storage rack 4, respectively.

[0102] In some embodiments, the second side plate 430 is smaller in height, which reduces the gap between the first support plate 410 and the second storage rack 5, and reduces the height gap between the first support plate 410 and the second storage rack 5, thus preventing small items from falling into the height gap between the first support plate 410 and the second storage rack 5 and becoming difficult to retrieve.

[0103] Figure 9 for Figure 4 A schematic diagram of the second storage rack in the middle; Figure 10 for Figure 9 An exploded image.

[0104] like Figure 9 and Figure 10 As shown, in some embodiments, the second storage rack 5 may include a second bottom wall 51 and a third side wall 52. The second bottom wall 51 is spaced below the shelf 3, and can extend laterally along the refrigeration chamber 201 and is spaced parallel to the shelf 3. The third side wall 52 extends along the height direction of the refrigeration device, and the upper end of the third side wall 52 can be connected to the shelf 3, and the lower end of the third side wall 52 can be connected to the end of the second bottom wall 51 near the first side wall 41.

[0105] The first accommodating space is formed between the bottom surface of the shelf 3, the first side wall 41, the first bottom wall 42, and the third side wall 52; the second accommodating space is formed between the bottom surface of the shelf 3, the third side wall 52, and the second bottom wall 51. Two second sliding parts 45 are slidably connected to the opposite two sides of the second bottom wall 51.

[0106] Specifically, the first storage space is located on one side of the third side wall 52, and the second storage space is located on the other side of the third side wall 52. The third side wall 52 divides the space below the shelf 3, thus forming the first storage space 401 and the second storage space arranged horizontally adjacent to each other. In this way, the first storage rack 4 and the second storage rack 5 can subdivide the storage area below the shelf 3. Users can classify and store items in different storage spaces according to their size, shape, and frequency of use, which helps to make full use of the three-dimensional space in the refrigeration room 201 and greatly improves the space utilization rate.

[0107] On the other hand, the first storage rack 4 and the second storage rack 5 are connected by the second sliding part 45, which is slidably connected to the second bottom wall 51, and the third side wall 52 is connected to the shelf 3, so that the shelf 3, the first storage rack 4 and the second storage rack 5 form a mutually supporting structure, which improves the structural stability of the first storage rack 4 and the second storage rack 5.

[0108] In some embodiments, the second storage rack 5 may include a second support plate 510 and a third side plate 520, which may be L-shaped. A second bottom wall 51 may be disposed on the top surface of the second support plate 510, and a third side wall 52 may be disposed on the third side plate 520. The second support plate 510 may be spaced above the first support plate 410. During movement of the first storage rack 4, the area of ​​the first support plate 410 at the bottom of the second support plate 510 can be increased or decreased, thereby adjusting the length of the first storage space 401 and thus changing its volume.

[0109] In some embodiments, the second storage space 501 may be formed between the bottom surface of the shelf 3, the third side wall 52, the second bottom wall 51, and one side wall of the inner box 2.

[0110] In some embodiments, a roller or ball bearing may be movably disposed within the second slide groove 403, the roller being rotatably disposed between the groove wall of the second slide groove 403 and the second support plate 510. Rollers may also be used when the length of the second slide groove 403 is short or when installation space is insufficient.

[0111] Because the second sliding part 45 is prone to frictional damage at the contact point between the second support plate 510 and the second sliding part 45 during sliding, by setting a roller in the second slide groove 403, the sliding friction between the groove wall of the second slide groove 403 and the second support plate 510 is transformed into rolling friction, making the movement of the second support plate 510 within the second slide groove 403 smoother. This avoids wear and tear between the first storage rack 4 and the second storage rack 5 due to frequent sliding friction during long-term use, which would increase the surface roughness of the components and affect the smoothness of sliding, thus improving the durability of the first storage rack 4 and the second storage rack 5.

[0112] like Figure 9 and Figure 10As shown, in some embodiments, the second storage rack 5 may include a fourth sidewall 53. The fourth sidewall 53 and the third sidewall 52 are respectively disposed at the two lateral ends of the second bottom wall 51. The fourth sidewall 53 extends along the height direction of the refrigeration device, with its lower end connected to the second bottom wall 51 and its upper end extending to the shelf 3, and connected to the shelf 3. A second accommodating space is formed between the bottom surface of the shelf 3, the third sidewall 52, the second bottom wall 51, and the fourth sidewall 53.

[0113] The fourth side wall 53 and the third side wall 52 are located at opposite ends of the second bottom wall 51. The bottom surface of the shelf 3, the third side wall 52, the second bottom wall 51, and the fourth side wall 53 can form a relatively enclosed U-shaped structure. This makes the second storage space 501 a relatively regular and enclosed area, making it easier for users to classify and store items and plan their layout, thus improving the orderly use of space.

[0114] On the other hand, the upper end of the fourth side wall 53 is connected to the shelf 3, and the lower end of the fourth side wall 53 is connected to the second bottom wall 51. This allows the opposite sides of the second bottom wall 51 to be connected to the shelf 3 via the third side wall 52 and the fourth side wall 53, respectively, thus forming a stable frame structure. This facilitates the more stable and reliable placement of the second storage rack 5 within the refrigeration chamber 201, and allows for more even stress distribution when the second storage rack 5 bears the weight of items. Furthermore, the second sliding parts 45 of the first storage rack 4 are slidably connected to the opposite edges of the second bottom wall 51. Due to the stable frame structure of the second storage rack 5, the movement of the first storage rack 4 along the shelf 3 is more stable and reliable. At the same time, it reduces swaying and vibration caused by sliding, making the sliding process smoother and more stable.

[0115] In some embodiments, the second storage rack 5 may include a fourth side plate 530, and the fourth side wall 53 may be disposed on the fourth third side plate 520.

[0116] It should be noted that in some embodiments, the second storage rack 5 may also be in the form of a basket, and a second bottom wall 51 is formed at the bottom of the second storage rack 5 accordingly, and a third side wall 52 and a fourth side wall 53 are formed on the opposite sides of the second storage rack 5 respectively.

[0117] Figure 11 for Figure 2 A schematic diagram showing the state of the second storage rack after it has been moved.

[0118] like Figure 11 As shown, in some embodiments, the upper end of the third sidewall 52 is slidably connected to the shelf 3, and the upper end of the fourth sidewall 53 is slidably connected to the shelf 3.

[0119] The upper ends of the third sidewall 52 and the fourth sidewall 53 are slidably connected to the shelf 3, allowing the second storage rack 5 to move along the length of the shelf 3 and thus adjust its position within the cooling space by horizontal extension and retraction. This allows the user to adjust the volume of the first storage space 401 by moving the first storage rack 4, and also to adjust the volume of the first storage space 401 by moving the second storage rack 5, which can slide relative to the first storage rack 4.

[0120] On the other hand, when a user needs to place tall items on one side of the bottom of the second storage rack 5, they can move the second storage rack 5 to facilitate storage. In this way, the first storage rack 4 and the second storage rack 5 can move laterally along the shelf 3, allowing users to selectively move them according to their usage habits, item classification needs, and different storage requirements during actual use. This provides greater flexibility in space adjustment, enabling the refrigeration unit to better meet users' personalized needs, improving space utilization and product practicality.

[0121] like Figure 9 and Figure 10 As shown, in some embodiments, the second storage rack 5 may include a third sliding part 54, which extends along the length of the shelf 3. One end of the third sliding part 54 is connected to the third side wall 52, and the other end of the third sliding part 54 is connected to the fourth side wall 53. The third sliding part 54 is slidably connected to the shelf 3.

[0122] Specifically, by providing a third sliding part 54 connected to the top of the third side wall 52 and the top of the fourth side wall 53, and simultaneously slidably connected to the shelf 3, the third sliding part 54 can synchronously drive the third side wall 52 and the fourth side wall 53 to move within the refrigeration compartment 201 during the sliding process relative to the shelf 3. This allows the second storage rack 5 to move stably and reliably relative to the shelf 3, thereby adjusting the position of the second storage rack 5 within the refrigeration compartment 201. On the other hand, the third sliding part 54, which is supported and connected between the third side wall 52 and the fourth side wall 53, can improve the overall structural strength of the second storage rack 5. During the sliding process, the third sliding part 54 can guide the third side wall 52 and the fourth side wall 53 to slide smoothly along a predetermined trajectory along the length of the shelf 3, reducing wobbling and offset during the sliding process, and reducing wear and friction between the sliding components.

[0123] In some embodiments, the third sliding portion 54 includes two parts. One third sliding portion 54 is disposed between one side of the top of the third sidewall 52 and the fourth sidewall 53, and the other third sliding portion 54 is disposed between the other side of the top of the third sidewall 52 and the fourth sidewall 53. The two third sliding portions 54 are slidably connected to opposite side edges of the shelf 3. Specifically, one third sliding portion 54 is slidably connected to the front side of the shelf 3, and the other third sliding portion 54 is slidably connected to the rear side of the shelf 3. The third sliding portion 54 is disposed adjacent to the first sliding portion 43.

[0124] The two third sliding parts 54 are respectively connected to the opposite sides of the top of the third side wall 52 and the fourth side wall 53, and are slidably connected to the opposite sides of the shelf 3, so that the second storage rack 5 forms a bidirectional sliding connection structure with the shelf 3. During the sliding process, the two third sliding parts 54 can be subjected to force and work together, and can more evenly distribute the friction and gravity generated when the side wall moves. This not only makes the sliding operation easy and effortless, but also allows the third side wall 52, the fourth side wall 53 and the second bottom wall 51 to maintain a stable state during the sliding process, avoiding problems such as side wall tilting and jamming caused by uneven force on one side.

[0125] In some embodiments, the third sliding part 54 may be provided with a third sliding groove 502, which may have a certain length and the length of the third sliding groove 502 extends along the length direction of the shelf 3. The third sliding groove 502 located on the front side opens to the rear and is slidably connected to the front side of the shelf 3, while the third sliding groove 502 located on the rear side opens to the front and is slidably connected to the rear side of the shelf 3.

[0126] The third slide groove 502 located on the front side can be slidably connected to the front trim strip 32 of the shelf 3, and the third slide groove 502 located on the rear side can be slidably connected to the rear trim strip 33.

[0127] In some embodiments, the two third sliding portions 54, the third side plate 520, and the fourth side plate 530 can be integrally formed. The second support plate 510 is detachably disposed on the third side plate 520 and the fourth side plate 530, wherein the bottom of the third side plate 520 and the fourth side plate 530 are respectively provided with supporting ribs, and the opposite sides of the second support plate 510 can be respectively supported on the top of the supporting ribs.

[0128] In some embodiments, a roller or ball bearing may be movably disposed in the third chute 502, and the roller is rotatably disposed between the chute wall of the third chute 502 and the shelf 3.

[0129] Because the third sliding part 54 is prone to frictional damage at the contact point between the shelf 3 and the third sliding part 54 during sliding, by setting rollers in the third sliding groove 502, the sliding friction between the groove wall of the third sliding groove 502 and the shelf 3 is transformed into rolling friction, making the movement of the shelf 3 within the third sliding groove 502 smoother. This avoids wear caused by frequent sliding friction between the second storage rack 5 and the shelf 3 during long-term use, which would increase the surface roughness of the components and affect the smoothness of sliding, thus improving the durability of the second storage rack 5.

[0130] In some other embodiments, the second bottom wall 51 can be slidably connected to the bottom of the shelf 3 via support rods (not shown in the figure). The lower end of the support rod can be connected to the first bottom wall 42, and the upper end of the support rod can be slidably connected to the shelf 3. There can be four support rods, with two support rods located on opposite sides of the front end of the second bottom wall 51 and the other two support rods located on opposite sides of the rear end of the second bottom wall 51.

[0131] Figure 12 for Figure 4 A schematic diagram of another state.

[0132] like Figure 12 As shown, in some embodiments, the third sidewall 52 is provided with a first support rib 55 on one side of the first storage space 401, and the first support rib 55 may be spaced apart above the second bottom wall 51. The fourth sidewall 53 is provided with a second support rib 56 on one side of the first storage space 401, and the second support rib 56 may be spaced apart above the second bottom wall 51. The first support rib 55 and the second support rib 56 may be arranged opposite to each other, and the first support rib 55 and the second support rib 56 are located on the same horizontal plane.

[0133] The refrigeration device may include a support plate 6, which is detachably disposed in the second storage rack 5. The support plate 6 is disposed in the first storage space 401, and the bottom of the opposite sides of the support plate 6 is supported on the top surfaces of the first support rib 55 and the second support rib 56, respectively.

[0134] Specifically, the first support rib 55 and the second support rib 56 are spaced apart above the second bottom wall 51, providing a stable support structure for the support plate 6. This allows the support plate 6 to evenly distribute the weight of the items onto the third side wall 52, the fourth side wall 53, and the second bottom wall 51, enhancing the structural load-bearing capacity of the entire second storage rack 5. Even when storing heavy items, deformation or damage to the support plate 6 can be avoided. Furthermore, users can remove or install the support plate 6 within the first storage space 401 according to the actual height requirements of the stored items. By installing the support plate 6 within the first storage space 401, the support plate 6 can divide the first storage space 401 into two storage spaces arranged vertically, thereby achieving multi-level layered storage within the first storage space 401. This facilitates full utilization of the height space of the first storage space 401 and increases the overall storage capacity.

[0135] In some embodiments, multiple support plates 6 may be provided. Correspondingly, the first support rib 55 and the second support rib 56 may be provided to support multiple support plates 6 respectively. Multiple support plates 6 can divide the second storage space 501 into multiple storage spaces arranged vertically, thereby improving space utilization.

[0136] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
