Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology and relates to the structure of the built-in storage box of a micro-frost refrigerator. Background Technology

[0002] The built-in storage compartment of the micro-frost refrigerator is a specially designed storage space inside the refrigerator. Its core is to control the humidity inside the compartment at a low level by optimizing the refrigeration system and humidity management technology, thereby significantly reducing the frost on the surface of food and the inner wall of the storage compartment, thus further improving the storage effect, while also taking into account moisture prevention, odor prevention and convenience.

[0003] To facilitate more precise classification and management of food stored inside the built-in storage compartment of a frost-free refrigerator, dividers are typically installed to create separate spaces. However, traditional dividers are often fixed structures, making it difficult to adjust their position. This can easily lead to problems such as wasted space and confusion in classification due to varying food sizes or changing storage needs. Therefore, a new built-in storage compartment structure for frost-free refrigerators is proposed to address these issues. Utility Model Content

[0004] The technical problem this utility model aims to solve is that, in order to facilitate more precise classification and management of food stored inside the built-in storage box of a micro-frost refrigerator, a partition is usually installed to divide the space into independent areas. However, traditionally designed partitions are mostly fixed structures, and their positions are inconvenient to adjust. This often leads to problems such as wasted space and confusion in classification due to different food sizes or changes in storage needs.

[0005] The microfrost refrigerator built-in storage box structure described in this utility model includes a microfrost refrigerator built-in storage box body, an internal handle installed on the end face of the microfrost refrigerator built-in storage box body, an adjustment component provided in the middle of the microfrost refrigerator built-in storage box body, an isolation plate connected to the middle of the microfrost refrigerator built-in storage box body through the adjustment component, and an auxiliary support component provided at the bottom of the isolation plate.

[0006] The adjustment assembly includes a first horizontal groove, a second horizontal groove, a vertical groove, and a guide support rod. The first horizontal groove is located in the middle of the side of the inner storage box of the micro-frost refrigerator near the inner handle. The second horizontal groove is located in the middle of the side of the inner storage box of the micro-frost refrigerator away from the inner handle. The vertical groove is located on one side of the inner storage box of the micro-frost refrigerator. The two ends of the guide support rod are respectively fixed to the two ends of the first horizontal groove.

[0007] The adjustment assembly also includes a lead screw, a threaded slider, and a guide slider. The two ends of the lead screw are rotatably connected to the two ends of the second transverse groove, the threaded slider is threadedly connected to the middle of the lead screw, and the guide slider is slidably connected to the middle of the guide support rod.

[0008] The adjustment assembly also includes two sets of connecting rods, two sets of sliding grooves, and an adjustment shaft. The ends of the two connecting rods that are far apart from each other are respectively fixed to the sides of the threaded slider and the guide slider that are close to each other. The ends of the two connecting rods that are close to each other are respectively fixed to the middle of the two sides of the isolation plate. The two sliding grooves are respectively opened on the side of the main body of the built-in storage box of the micro-frost refrigerator near the second horizontal groove and the first horizontal groove. The middle parts of the two sets of connecting rods are slidably connected to the middle of the two sets of sliding grooves. One end of the adjustment shaft is rotatably connected to the end of the vertical groove near the built-in handle.

[0009] The adjustment assembly also includes a worm, an adjustment head, and a worm wheel. One end of the worm is fixed to the end of the adjustment shaft near the lead screw, and the other end of the worm is rotatably connected to the end of the vertical groove away from the built-in handle. The adjustment head is fixed to the end of the lead screw near the worm, and the worm wheel is fixed to the end of the adjustment shaft away from the worm.

[0010] The worm and worm wheel mesh with each other.

[0011] The auxiliary support assembly includes two sets of support columns and two sets of U-shaped plates. The tops of the two support columns are respectively fixed to the bottom sides of the isolation plate, and the two U-shaped plates are respectively fixed to the bottoms of the two sets of support columns.

[0012] The auxiliary support assembly also includes two sets of rotating shafts and two sets of rollers. The two ends of the two rotating shafts are respectively rotatably connected to the two sides of the two sets of U-shaped plates, and the middle parts of the two rollers are respectively fixed to the middle of the two sets of rotating shafts.

[0013] The bottom of both rollers is in contact with the inner bottom of the main body of the built-in storage box of the micro-frost refrigerator.

[0014] The isolation plate has multiple sets of ventilation holes in the middle.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by rotating the adjustment head, the partition plate can be moved, thereby flexibly adjusting the position of the partition plate. This allows for free adjustment of the partition layout according to the size, quantity, or preservation needs of the food, which not only greatly improves space utilization but also reduces the possibility of localized crowding or emptying inside the main body of the frost-free refrigerator due to the fixed position of the partition plate. This allows different foods to obtain a more precise storage environment and enhances the convenience for users to dynamically optimize the internal structure of the refrigerator according to their daily habits.

[0016] By setting up auxiliary support components, the isolation plate can be supported, thereby improving its stability and reducing friction between the bottom of the isolation plate and the bottom of the internal storage box of the micro-frost refrigerator when it moves, thus improving the smoothness of the isolation plate's movement.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1 like Figures 1 to 7 As shown, the built-in storage box structure of the micro-frost refrigerator includes a built-in storage box body 1, a built-in handle 11 installed on the end face of the built-in storage box body 1, an adjustment component in the middle of the built-in storage box body 1, an isolation plate 12 connected to the middle of the built-in storage box body 1 through the adjustment component, and an auxiliary support component at the bottom of the isolation plate 12.

[0031] The adjustment assembly includes a first horizontal groove 2, a second horizontal groove 21, a vertical groove 22, and a guide support rod 23. The first horizontal groove 2 is located in the middle of the side of the inner storage box body 1 of the micro-frost refrigerator near the inner handle 11. The second horizontal groove 21 is located in the middle of the side of the inner storage box body 1 of the micro-frost refrigerator away from the inner handle 11. The vertical groove 22 is located on one side of the inner storage box body 1 of the micro-frost refrigerator. The two ends of the guide support rod 23 are respectively fixed to the two ends of the first horizontal groove 2.

[0032] The adjustment assembly also includes a lead screw 3, a threaded slider 31, and a guide slider 32. The two ends of the lead screw 3 are rotatably connected to the two ends of the second transverse groove 21, the threaded slider 31 is threadedly connected to the middle of the lead screw 3, and the guide slider 32 is slidably connected to the middle of the guide support rod 23.

[0033] The adjustment assembly also includes two sets of connecting rods 4, two sets of sliding grooves 41, and an adjustment shaft 42. The ends of the two connecting rods 4 that are far apart from each other are respectively fixed to the sides of the threaded slider 31 and the guide slider 32 that are close to each other. The ends of the two connecting rods 4 that are close to each other are respectively fixed to the middle of the two sides of the isolation plate 12. The two sliding grooves 41 are respectively opened on the side of the built-in storage box body 1 of the micro-frost refrigerator near the second horizontal groove 21 and the first horizontal groove 2. The middle parts of the two sets of connecting rods 4 are respectively slidably connected to the middle of the two sets of sliding grooves 41. One end of the adjustment shaft 42 is rotatably connected to the end of the vertical groove 22 near the built-in handle 11.

[0034] The adjustment assembly also includes a worm 5, an adjustment head 51, and a worm wheel 52. One end of the worm 5 is fixed to the end of the adjustment shaft 42 near the lead screw 3, and the other end of the worm 5 is rotatably connected to the end of the vertical groove 22 away from the built-in handle 11. The adjustment head 51 is fixed to the end of the lead screw 3 near the worm 5, and the worm wheel 52 is fixed to the end of the adjustment shaft 42 away from the worm 5.

[0035] The worm 5 and the worm wheel 52 mesh with each other.

[0036] During operation, when the position of the partition plate 12 needs to be adjusted according to the size of the food to be stored, the adjustment head 51 can be rotated to drive the adjustment shaft 42 to rotate. The rotation of the adjustment shaft 42 will drive the worm 5 to rotate. At this time, since the worm 5 and the worm wheel 52 are in a meshing state, the rotation of the worm 5 will drive the worm wheel 52 to rotate, and the rotation of the worm wheel 52 will drive the lead screw 3 to rotate. The rotation of the lead screw 3 will synchronously drive the slide groove 41 to move.

[0037] During the movement of the threaded slider 31, the connecting rod 4 will drive the isolation plate 12 and the guide slider 32 to move. At this time, the guide slider 32 is restricted by the guide support rod 23 and can only slide in a straight line in the middle of the guide support rod 23. This can change the movement trajectory of the isolation plate 12 and the threaded slider 31, so that it moves in a straight line with the guide slider 32 until the position of the isolation plate 12 is adjusted to a suitable position. Then the adjustment head 51 can be stopped to complete the adjustment of the isolation plate 12.

[0038] This step involves rotating the adjustment head 51 to drive the partition plate 12 to move, thereby flexibly adjusting the position of the partition plate 12. This allows for free adjustment of the partition layout according to the size, quantity, or preservation needs of the food, which not only greatly improves space utilization but also reduces the possibility of localized crowding or emptying inside the main body 1 of the microfrost refrigerator due to the fixed position of the partition plate 12. This provides a more precise storage environment for different foods and enhances the convenience for users to dynamically optimize the internal structure of the refrigerator according to their daily habits.

[0039] Example 2 like Figure 2 , Figure 6 and Figure 7 As shown, the auxiliary support assembly includes two sets of support columns 7 and two sets of U-shaped plates 71. The tops of the two support columns 7 are respectively fixed to the bottom sides of the isolation plate 12, and the two U-shaped plates 71 are respectively fixed to the bottoms of the two sets of support columns 7.

[0040] The auxiliary support assembly also includes two sets of rotating shafts 8 and two sets of rollers 81. The two ends of the two rotating shafts 8 are rotatably connected to the two sides of the two sets of U-shaped plates 71, and the middle parts of the two rollers 81 are fixed to the middle of the two sets of rotating shafts 8.

[0041] The bottoms of both rollers 81 are in contact with the inner bottom of the main body 1 of the built-in storage box of the micro-frost refrigerator.

[0042] When the isolation plate 12 moves, it will drive the support column 7 to move synchronously. The movement of the support column 7 will drive the U-shaped plate 71, the rotating shaft 8 and the roller 81 to move. During the movement, the roller 81 will generate friction with the bottom of the internal storage box 1 of the micro-frost refrigerator. Under the action of friction, the roller 81 can be driven to roll. In this way, with their cooperation, the isolation plate 12 can be provided with auxiliary support.

[0043] This step, through the setting of auxiliary support components, can support the isolation plate 12, thereby improving the stability of the isolation plate 12, and can also reduce the friction between the bottom of the isolation plate 12 and the bottom of the main body 1 of the built-in storage box of the micro-frost refrigerator when it moves, thereby improving the smoothness of the movement of the isolation plate 12.

[0044] Example 3 like Figure 1 , Figure 2 and Figure 6 As shown, multiple sets of ventilation holes 10 are provided in the middle of the isolation plate 12.

[0045] When in operation, when the partition plate 12 divides the interior of the built-in storage box 1 of the micro-frost refrigerator into two storage spaces, the food attached to both sides of the partition plate 12 can be ventilated through the ventilation holes 10.

[0046] This step, through the setting of the ventilation holes 10, can promote air circulation inside the main body 1 of the built-in storage box of the micro-frost refrigerator, reduce the uneven temperature caused by poor air circulation in local enclosed spaces, thereby reducing the risk of food spoilage due to temperature differences. In addition, the air circulation can accelerate the diffusion and dilution of odors, keeping the smell inside the box fresh.

[0047] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
