Detailed implementation manners

[0032] The embodiments will be described in detail below, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

They are only examples of systems and methods consistent with some aspects of the present application detailed in the claims.

[0033] A refrigerator is a refrigerating household appliance, and its main functions include refrigeration, freezing, freshness preservation, temperature adjustment, etc. By circulating refrigerant, the internal temperature is reduced to achieve the purpose of keeping food fresh. Among them, in order to increase the convenience of storage and realize the hierarchical storage of food materials, a shelf is provided in the box body 1. The two common shelf structure methods are the ribbed shelf and the cantilever beam 322 shelf. The ribbed shelf is placed and installed on the raised ribs symmetrically arranged on the side wall of the refrigerator inner liner, with a simple structure and convenient assembly; the cantilever beam 322 shelf is supported and installed by the cantilever structure on the rear wall of the box liner, and there are no ribs on the side wall of the box liner, with a simple appearance. However, when placing relatively tall items and needing to adjust the shelf spacing, due to the limitation of the structure, it is necessary to take out the food materials from the shelf, take out the shelf from the assembly structure, and then put the food materials back on the shelf after the adjustment is completed, which is inconvenient to adjust. At the same time, the self-weight of the shelf is relatively large, and it is laborious for users to hold it up when adjusting the shelf. For the ribbed shelf, when the refrigerator is embedded in the cabinet, due to the limitation of the opening angle, the shelf cannot be pulled out from the refrigerator, and the height adjustment of the shelf cannot be realized. The upper shelf is relatively high, which is not conducive to the taking and placing of food materials and has a low usage frequency.

[0034] To solve the problem that the height of the refrigerator shelf is not easy to adjust. Refer to Figure 1 and Figure 2, some embodiments of the present application provide a shelf assembly, including: a storage shelf 32, including a shelf board 321 and cantilever beams 322 symmetrically arranged on both sides of the shelf board 321; wherein, the shelf board 321 is mainly used to divide the refrigerator compartment into several areas, and the material of the shelf board 321 is mainly made of glass, plastic or metal. The cantilever beams 322 are fixed to the structure on both sides of the shelf board 321, and the function of the cantilever beams 322 is to support the shelf board 321 and allow the shelf board 321 to be suspended inside the refrigerator. The cantilever beams 322 can be made of metal or plastic, and are designed to be able to bear the weight of the items on the shelf board 321 without deformation.

[0035] A sliding assembly 31, including a sliding groove 311 and a sliding plate 312; symmetric steps 3111 are provided on both sides of the sliding groove 311; wherein, the protruding direction of the steps 3111 extends towards the inside of the sliding groove 311, so that symmetric sliding channels are formed inside the sliding groove 311. The sliding groove 311 is arranged along the vertical direction of the refrigerator cabinet 1. Groove rollers 313 are provided at both ends of the sliding plate 312, and the groove rollers 313 are inserted into the sliding groove 311 along the steps 3111 to make the sliding plate 312 slidably connected with the sliding groove 311; by setting the groove rollers 313, the groove rollers 313 can slide up and down along the steps 3111, and further the sliding plate 312 can slide up and down in the sliding groove 311. After connecting the sliding groove 311 with the storage shelf 32, the sliding groove 311 can drive the storage shelf 32 to move up and down, thereby facilitating the user to adjust the height of the storage shelf 32. For example, when the user needs to adjust the height of the storage shelf 32, the sliding plate 312 can be set at the required height first, and then the position of the sliding plate 312 can be fixed by a limiting member or a clamping member to achieve the effect of adjusting the height of the sliding plate 312. A first through hole 3122 is also provided on one side of the sliding plate 312 close to the refrigerator door body. The first through hole 3122 is a rectangular hole. Through the first through hole 3122, the cantilever beam 322 can be inserted into the first through hole 3122 to connect the storage shelf 32 with the sliding assembly 31. When the sliding member moves up and down in the sliding groove 311, the storage shelf 32 moves along with the movement of the sliding member.

[0036] In some embodiments, as Figure 6 shown, a first limiting groove 3221 is provided at one end of the cantilever beam 322 close to the shelf board 321, and a second limiting groove 3222 is provided at the end of the cantilever beam 322 far from the shelf board 321; a support column 3121 is provided inside the first through hole 3122, and a limiting baffle 3123 is provided at the lower end of the first through hole 3122. The cantilever beam 322 passes through the first through hole 3122, the first limiting groove 3221 abuts against the support column 3121, and the second limiting groove 3222 abuts against the limiting baffle 3123.

[0037] During installation, after one end of the cantilever beam 322 away from the shelf 321 passes through the first through hole 3122, the open end of the first limiting groove 3221 abuts against the support column 3121, and the open end of the second limiting groove 3222 abuts against the limiting baffle 3123. When the positions of the first limiting groove 3221 and the second limiting groove 3222 are correct, rotate the shelf 32 to rotate the cantilever beam 322, so that the support column 3121 slides into the first limiting groove 3221 and the limiting baffle 3123 slides into the second limiting groove 3222, and then use the support column 3121 and the limiting baffle 3123 as fulcrums to support the cantilever beam 322.

[0038] It can be understood that the main purpose of setting the first limiting groove 3221 and the second limiting groove 3222 is to facilitate the connection between the shelf 32 and the sliding assembly 31. The structures of the first limiting groove 3221 and the second limiting groove 3222 simplify the installation process, reduce the required connecting parts and tools, and also make the whole structure more compact and stable. After the shelf 32 is connected to the sliding assembly 31, when ingredients are placed on the shelf 32, the shelf 32 will be subjected to a large pressure, which will increase the connection stability between the first limiting groove 3221 and the support column 3121. At the same time, the connection between the second limiting groove 3222 and the limiting baffle 3123 can limit the rotation of the first limiting groove 3221 around the support column 3121 and improve the connection stability.

[0039] In some embodiments, as Figure 5 and Figure 6 shown, it further includes a stop bracket 314, and a plurality of stop grooves 3141 are uniformly arranged along the length direction of the stop bracket 314; the second limiting groove 3222 is provided with a stop lug 3223 extending towards the stop bracket 314; the stop lug 3223 abuts against the stop groove 3141. The second limiting groove 3222 is provided with a sliding hook 3224 extending towards the shelf 321. When the cantilever beam 322 rotates around the support column 3121, the sliding hook 3224 abuts against the lower end of the limiting baffle 3123.

[0040] When the shelf 32 needs to be adjusted, as Figure 7 shown, lift the front end of the shelf 32. After the first limiting groove 3221 rotates around the support column 3121 to a set angle, the stop lug 3223 disengages from the stop position. At the same time, the sliding hook 3224 hooks into the bottom end face of the sliding plate 312. At this time, the lifting adjustment of the shelf 32 can be realized under the support of human force. When adjusting the shelf 32 upward, setting the sliding hook 3224 can prevent the shelf 32 from detaching from the sliding plate 312.

[0041] When the storage needs to be removed, lift the storage rack 32 parallelly upwards until the first limit groove 3221 is disengaged from the support column 3121 and the second limit groove 3222 is disengaged from the limit baffle 3123, and then move the storage rack 32 out of the first through hole 3122 of the sliding plate 312.

[0042] In some embodiments, as Figure 3 shown, the sliding assembly 31 further includes a damper 315. One end of the damper 315 is provided with a gear 3151. A limit hole 3112 is provided on the side of the sliding groove 311 away from the sliding plate 312. The sliding plate 312 is provided with a rack. The damper 315 is inserted into the limit hole 3112, and the gear 3151 meshes with the rack. When the sliding plate 312 slides up and down, the rack drives the gear 3151 to rotate. Due to the limitation of the gear 3151, the sliding plate 312 can only slide within the length range of the rack. Therefore, the adjustment range of the storage rack 32 can be controlled by controlling the length of the rack. By providing the damper 315, when the storage rack 32 is adjusted downwards, the resistance of the damper 315 cancels out the self-weight of the storage rack 32 falling freely. When the storage rack 32 is adjusted upwards, the damper 315 has no resistance, and the adjustment of the storage rack 32 is easier.

[0043] In some embodiments, as Figure 4 shown, the cross-section of the step 3111 is arc-shaped. The distance between the steps 3111 is smaller than the outer diameter of the groove roller 313, and the distance between the steps 3111 is larger than the inner diameter of the groove roller 313.

[0044] Among them, the cross-section of the step 3111 is arc-shaped, which can make the stress distribution of the step 3111 more uniform when the step 3111 is subjected to the pressure of the roller, which is beneficial to improving the stability and load-bearing capacity of the step 3111. Secondly, the distance between the steps 3111 is designed considering the cooperation with the groove roller 313. The distance between the steps 3111 is smaller than the outer diameter of the groove roller 313, and the distance between the steps 3111 is larger than the inner diameter of the groove roller 313, which not only ensures that the roller can smoothly pass through the gap between the steps 3111, but also can limit the moving path of the groove roller 313 through the steps 3111, thereby reducing wear and increasing the service life.

[0045] In some embodiments, the cantilever beam 322 is provided with a plurality of reinforcing ribs, and the extending direction of the reinforcing ribs is the same as the direction of the shelf 321.

[0046] Among them, the reinforcing rib is mainly used to enhance the bending resistance of the cantilever beam 322, ensuring that the cantilever beam 322 can effectively resist bending stress when subjected to a load. The reinforcing rib is usually arranged along the length direction of the cantilever beam 322, that is, in the same direction as the shelf 321 connected to the cantilever beam 322, extending from one end of the cantilever beam 322 to the other end, so as to provide sufficient bearing capacity and stability. When the cantilever beam 322 bears a load, the stress can be dispersed and transmitted through the reinforcing rib, thereby reducing the risk of bending damage of the cantilever beam 322 when supporting the shelf. By setting the reinforcing rib, the strength of the cantilever beam 322 can be improved to facilitate the support of the shelf.

[0047] In some embodiments, it further includes a decorative cover 33. The decorative cover 33 is provided with a second through hole 331, and the length of the second through hole 331 is the same as the length of the rack. The decorative cover 33 is buckled with the sliding assembly 31, and the cantilever beam 322 passes through the second through hole 331 and the first through hole 3122 in sequence to be connected with the sliding assembly 31. During assembly, after the sliding assembly 31 is first fixed to the set positions on both sides of the back of the inner liner by screws, the decorative cover 33 is snap-connected to the front of the sliding assembly 31 and fixed to the inner liner by screws. The front of the decorative cover 33 is provided with a second through hole 331 that matches the adjustment range of the storage shelf 32. The storage shelf 32 can pass through the second through hole 331 to be fixedly connected with the sliding plate 312. By setting the decorative cover 33, the exposed structural members of the sliding assembly 31 and the rounded corners around the inner liner are blocked.

[0048] In some embodiments, as Figure 8 shown, an embodiment of the present application provides a refrigerator, including a box body 1 and the shelf assembly provided in the above embodiment. The box body 1 is provided with a storage compartment 2; the shelf assembly 3 is arranged in the storage compartment 2.

[0049] As can be seen from the above technical solutions, the present application provides a shelf assembly and a refrigerator. The shelf assembly includes: a storage shelf 32, which includes a shelf board 321 and cantilever beams 322 symmetrically arranged on both sides of the shelf board 321; a sliding assembly 31, which includes a sliding groove 311 and a sliding plate 312; symmetric steps 3111 are arranged on both sides of the sliding groove 311; groove rollers 313 are arranged at both ends of the sliding plate 312, and the groove rollers 313 are inserted into the sliding groove 311 along the steps 3111 to make the sliding plate 312 slidably connected to the sliding groove 311; a first through hole 3122 is further arranged on the sliding plate 312, and the cantilever beam 322 is inserted into the first through hole 3122 to connect the storage shelf 32 to the sliding assembly 31. By arranging the groove rollers 313 on the sliding plate 312, the sliding plate 312 can slide up and down in the sliding groove 311 along the steps 3111. The cantilever beam 322 is inserted into the first through hole 3122. When the height of the storage shelf 32 needs to be adjusted, the storage shelf 32 can be lifted, so that the cantilever beam 322 drives the sliding plate 312 to move in the sliding groove 311, realizing the lifting adjustment of the storage shelf 32, so as to solve the problem that the height of the refrigerator shelf is not easy to adjust.
