Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to a refrigerator shelf lifting device and a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a consumer product that keeps food or other items at a constant low temperature. Inside the refrigerator, there's a compressor, an ice maker (a cabinet or box for freezing ice), and a storage box with a refrigeration unit. As users' desire for a wider variety of food increases, ingredients need to be categorized and stored. Therefore, shelves are placed inside the refrigerator. These shelves serve as important storage devices and also as a means of separating and categorizing food. However, space within the refrigerator is limited. If the categorization space could be flexibly adjusted based on the size of the food, the refrigerator's storage capacity could be effectively increased.

[0003] Therefore, when using adjustable shelves to increase the storage capacity of food in the refrigerator, the adjustable shelf device needs to be manually cleared of food items above the shelf when it is operated, and manual adjustment is performed in an empty state, which makes the adjustment process complicated.

[0027] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0028] The refrigerator is equipped with shelves for placing food. To accommodate the height of different items, the shelves need to be height-adjustable. In some embodiments, multiple sets of equal-height ribs are installed on the inside of the refrigerator. When in use, the user places the shelves on ribs of different heights as needed to adjust the spacing between the shelves. Alternatively, the refrigerator's storage capacity for food can be increased by providing adjustable shelves. However, when adjusting the shelf height by providing equal-height ribs or adjustable shelves, the food above the shelf needs to be manually removed. Manual adjustment is performed in an unloaded state, which complicates the adjustment process and means that the shelves cannot be flexibly adjusted.

[0029] To solve the above problems, see Figure 1-Figure 2 Some embodiments of the present application provide a refrigerator shelf lifting device, including: a box body 1, a shelf 2, a lifting assembly 3 and a slide 4; the box body 1 includes side walls and a back panel, the slide 4 is connected to the back panel, the lifting assembly 3 includes a limit groove 31, the shelf 2 is connected to the lifting assembly 3 through the limit groove 31, the middle part of the slide 4 is concave inward, and limit blocks 41 are evenly provided on both sides of the slide 4. The lifting assembly 3 abuts against the limit blocks 41, and the two sides of the slide 4 are parallel to the side walls.

[0030] The chute 4 has a rear wall connected to the back panel, and two sides of the rear wall are provided with side edges perpendicular to the rear wall. Stoppers 41 are evenly spaced on both sides of the chute 4, and the stoppers 41 are cube-shaped. The chute 4 is embedded in the back panel and is removably connected to the back panel. For example, screw holes can be provided in the back panel and the rear wall, and the chute 4 and the back panel can be connected using screws. Alternatively, a snap-fit ​​structure can be provided in the back panel and the chute 4 to allow the back panel to be snap-fitted to the chute 4. This removable connection facilitates installation and removal.

[0031] The lifting assembly 3 is installed in the slide groove 4, and then the shelf 2 is set in the limit groove 31 of the lifting assembly 3. By controlling the position of the lifting assembly 3 in the slide groove 4, the height of the shelf 2 is controlled to achieve the effect of adjusting the height of the shelf 2.

[0032] The lifting assembly 3 abuts against the stopper 41, positioning the lifting assembly 3 within the chute 4. In some embodiments, the cross-sectional shape of the lifting assembly 3 is H-shaped. By configuring the lifting assembly 3 with an H-shaped cross-sectional shape, other components can be installed within the cavity structures on both sides of the lifting assembly 3, allowing the lifting assembly 3 to slide up and down within the chute 4 and also allowing the lifting assembly 3 to be fixed within the chute 4.

[0033] In some embodiments, the lifting assembly 3 includes a connecting portion 32, several adjustment blocks 33 and several springs 34; a cavity structure for accommodating the adjustment blocks 33 and the springs 34 is provided on both sides of the lifting assembly 3, and the springs 34 are symmetrically arranged in the cavity structure, one end of the spring 34 is connected to the connecting portion 32, and the other end of the spring 34 is connected to the adjustment block 33.

[0034] Under the action of the spring 34, the adjustment block 33 protrudes from the lifting assembly 3 and abuts against the limit block 41. The abutment between the limit block 41 and the adjustment block 33 allows the lifting assembly 3 to be set in the slide 4. When the height of the shelf 2 needs to be raised, the shelf 2 is supported and raised, and the lifting assembly 3 rises with the shelf 2. Under the action of the limit block 41 provided in the slide 4, the adjustment block 33 overcomes the elastic force of the spring 34 and moves toward the connecting portion 32. When the shelf 2 rises to the target position, the adjustment block 33 is reset under the action of the spring 34 and abuts against the limit block 41, completing the height adjustment of the shelf 2. When the height of the shelf 2 needs to be lowered, the adjusting block 33 can be controlled to move toward the connecting portion 32, and then the shelf 2 is supported. Under the action of the shelf 2's own weight and the supporting force, the lifting assembly 3 moves downward along the chute 4 along with the shelf 2. When it descends to the specified position, the adjusting block 33 is released, and the adjusting block 33 is reset under the action of the elastic force of the spring 34. The adjusting block 33 abuts against the limit block 41, and the height adjustment of the shelf 2 is completed. Under the action of the elastic force of the spring 34, the adjusting block 33 automatically pops out of the lifting assembly 3 and abuts against the limit block 41, so that the lifting assembly 3 abuts against the limit block 41 of the chute 4, thereby limiting the downward movement of the lifting assembly 3.

[0035] In some embodiments, the cavity structure is hollowed out on the side away from the chute 4. Figure 3As shown, when the shelf 2 needs to be controlled to descend, the adjusting block 33 abuts against the limiting block 41, and the lifting assembly 3 needs to retract the adjusting block 33 into the lifting assembly 3 before the lifting assembly 3 can be controlled to descend to the specified height. By hollowing out the side of the cavity structure away from the chute 4, it is convenient to control the adjusting block 33 to retract into the cavity structure of the lifting assembly 3. After the adjusting block 33 is retracted into the lifting assembly 3 and the lifting assembly 3 is controlled to descend to the specified height, the adjusting block 33 is released, and the adjusting block 33 automatically pops out under the action of the elastic force of the spring 34. After the adjusting block 33 abuts against the limiting block 41, the height adjustment of the shelf 2 is completed. One side of the lifting assembly 3 is hollowed out to facilitate the control of the adjusting block 33 to retract into the lifting assembly 3.

[0036] In some embodiments, as Figure 4 As shown, the adjustment block 33 has a first side 331 and a second side 332. The first side 331 is connected to a spring 34. The first side 331 is parallel to the connecting portion 32, and the second side 332 extends perpendicular to the extending direction of the side of the chute 4. The first side 331 is connected to at least one spring 34. When there are fewer springs 34, the spring 34 has a weak elastic force, slowing the return of the adjustment block 33. When there are more springs 34, the elastic force of the multiple springs 34 is greater, making it difficult to control the retraction of the adjustment block 33 into the lifting assembly 3. In this embodiment, each adjustment block 33 is connected to two springs 34, which allows for faster return of the adjustment block 33 retracted into the lifting assembly 3 and facilitates control of the retraction of the adjustment block 33 into the lifting assembly 3.

[0037] The extension direction of the second side 332 is perpendicular to the extension direction of the side of the slide groove 4, so that when the second side 332 abuts the limit block 41, the contact area between the second side 332 and the limit block 41 is increased, and the stability of the adjustment block 33 when abutting the limit block 41 is increased. At the same time, the second side 332 is in the same direction as the side of the lifting assembly 3, which can reduce the friction resistance of the adjustment block 33 popping out or entering the lifting assembly 3.

[0038] In some embodiments, the cross-sectional shape of the adjusting block 33 is fan-shaped. When the shelf 2 rises, the shelf 2 drives the lifting assembly 3 to rise. When the adjusting block 33 hits the limit block 41, the adjusting block 33 is squeezed by the limit block 41, thereby overcoming the elastic force of the spring 34 and moving toward the connecting portion 32. When the height of the adjusting block 33 exceeds the limit block 41, the adjusting block 33 is reset by the spring 34. The adjusting block 33 is a fan-shaped structure, which enables the adjusting block 33 to move toward the connecting portion 32 when it hits the limit block 41. Figure 5As shown, the cross-sectional shape of the adjustment block 33 can also be a right triangle. After the hypotenuse of the adjustment block 33 is squeezed by the limit block 41, it can overcome the elastic force of the spring 34 and move toward the connecting portion 32. When the lifting assembly 3 moves upward in the chute 4, it is not restricted by the adjustment block 33 and the limit block 41. When the lifting assembly 3 moves downward in the chute 4, the adjustment block 33 abuts the limit block 41, restricting the downward movement of the lifting assembly 3.

[0039] In some embodiments, a groove 333 is provided on one side of the adjustment block 33 close to the spring 34. By providing the groove 333 on the adjustment block 33, when the adjustment block 33 is controlled to move toward the connecting portion 32, the groove 333 can provide a fulcrum when the adjustment block 33 is controlled to move toward the connecting portion 32, which is beneficial for controlling the adjustment block 33 to move toward the connecting portion 32.

[0040] In order to facilitate the control of the adjustment block 33 to move toward the connecting portion 32, a handle structure can be provided on the side of the adjustment block 33 close to the spring 34. By pushing the handle structure toward the connecting portion 32, the movement of the adjustment block 33 can be controlled more easily.

[0041] In some embodiments, the horizontal spacing between two adjacent limit blocks 41 is equal to the width of the lifting assembly 3; the inward recess of the chute 4 is equal to the thickness of the lifting assembly 3. The lifting assembly 3 is positioned within the chute 4, and the width of the lifting assembly 3 is equal to the horizontal spacing between two adjacent limit blocks 41, allowing the lifting assembly 3 to slide within the chute 4. The adjustment block 33 abuts against the limiter to limit the movement of the lifting assembly 3. By setting the inward recess of the chute 4 to the thickness of the lifting assembly 3, when the lifting assembly 3 is positioned within the chute 4, the side surfaces of the lifting assembly 3 do not protrude beyond the side surfaces of the chute 4, and thus do not occupy the volume within the housing 1.

[0042] In some embodiments, a guide rod 5 and a support frame 21 are further provided in the box body 1; the guide rod 5 is symmetrically arranged on both sides of the back plate, and connecting plates are provided at both ends of the guide rod 5. The connecting plates are provided with screw holes, and the guide rod 5 is fixed to the back plate by screws. The guide rod 5 is arranged perpendicular to the horizontal direction, and the guide rod 5 is a "F"-shaped structure. The distance from the middle section of the guide rod 5 to the back plate is equal to the thickness of the lifting assembly 3, and a second groove is provided in the middle section of the guide rod 5. The support frame 21 is a triangular structure, and the support frame 21 is symmetrically arranged on both sides of the shelf 2, and the support frame 21 is fixedly connected to the shelf 2. For example, the shelf 2 and the support frame 21 are an integrally formed structure, and the shelf 2 and the support frame 21 can also be connected together by bonding. Fixedly connecting the shelf 2 and the support frame 21 can increase the connection strength between the shelf 2 and the support frame 21, and reduce the possibility of breakage at the connection between the shelf 2 and the support frame 21 during use. On the one hand, the support frame 21 can provide support for the shelf 2, reducing the situation where the shelf 2 is subjected to greater force when more items are placed on the shelf 2, which may cause damage to the shelf 2. On the other hand, the support frame 21 is connected to the guide rod 5, and the support frame 21 can slide up and down in the second groove. When the shelf 2 moves up and down to adjust the height, the support frame 21 can play a guiding role and can also limit the shelf 2 so that the shelf 2 cannot move left and right, but can only move up and down.

[0043] Based on the refrigerator shelf lifting device provided in the above embodiments, some embodiments of the present application provide a refrigerator, which is equipped with the refrigerator shelf lifting device provided in the above embodiments.

[0044] Insert shelf 2 into the limiting slot 31 of lifting assembly 3, then position lifting assembly 3 in slide slot 4. Pop out the adjustment block 33 of lifting assembly 3 and engage it with the limiting block 41. Finally, engage the support frames 21 on both sides of shelf 2 with the guide rods 5. When the height of shelf 2 needs to be increased, support shelf 2 is raised. As lifting assembly 3 rises with shelf 2, the adjustment block 33, squeezed by the limiting block 41, overcomes the elastic force of spring 34 and moves toward the connecting portion 32, allowing lifting assembly 3 to continue rising. When lifting assembly 3 reaches the target position, the adjustment block 33 is reset under the elastic force of spring 34, abutting against the limiting block 41 to prevent shelf 2 from descending due to gravity. During the ascent, the support frames 21 rise along the second groove. When the shelf 2 descends, a force is applied to the adjusting block 33 in the opposite direction to the connecting portion 32, so that the adjusting block 33 overcomes the elastic force of the spring 34 and moves toward the connecting portion 32. The shelf 2 moves downward under the combined action of the supporting force and gravity. When the lifting assembly 3 descends to the target position, the force applied to the adjusting block 33 is removed, and the adjusting block 33 is reset under the action of the elastic force of the spring 34. The adjusting block 33 abuts against the limit block 41, thereby achieving the effect of flexibly adjusting the height of the shelf 2.

[0045] The present application provides a refrigerator shelf lifting device and a refrigerator, the refrigerator shelf lifting device comprising: a housing 1, a shelf 2, a lifting assembly 3, and a chute 4; the housing 1 comprises side walls and a back panel, the chute 4 is connected to the back panel, the lifting assembly 3 comprises a limiting groove 31, the shelf 2 is connected to the lifting assembly 3 via the limiting groove 31, the middle portion of the chute 4 is recessed inward, limiting blocks 41 are evenly provided on both sides of the chute 4, the lifting assembly 3 abuts against the limiting blocks 41, and the sides of the chute 4 are parallel to the side walls. The lifting assembly 3 is installed in the chute 4, and then the shelf 2 is set in the limiting groove 31 of the lifting assembly 3. By controlling the position of the lifting assembly 3 in the chute 4, the height of the shelf 2 is controlled, thereby achieving the effect of adjusting the height of the shelf 2, thereby solving the problem that the shelf cannot be flexibly adjusted.
