Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0032] The following is combined with Figures 1 to 6 This invention describes the guide rail plate, the sealed drawer structure, and the refrigerator provided by this utility model.

[0033] See Figure 1 and Figure 2 As shown, the guide rail plate 100 provided in this embodiment of the present invention includes: a guide rail plate body 110, a guide rail structure 120, and a support structure 130.

[0034] The guide rail plate body 110 is configured to be fixedly connected to the inner liner 400 of the refrigerator; the guide rail structure 120 is provided on the guide rail plate body 110, and the guide rail structure 120 is used to support and guide the sealed drawer 200; the support structure 130 is provided on the guide rail plate body 110, and the support structure 130 is used to support the sealed cover plate 300.

[0035] The guide rail plate 100 provided by this utility model has both the guide rail structure 120 and the support structure 130 disposed on the guide rail plate body 110. In use, the guide rail body is fixedly connected to the inner liner 400 of the refrigerator. When the inner liner 400 of the refrigerator has insufficient processing precision or deforms, the guide rail structure 120 and the support structure 130 can be offset synchronously and by the same amount. This can effectively ensure the sealing effect of the sealing cover 300 on the sealing drawer 200, and solve the defect that the sealing cover 300 of the existing refrigerator cannot effectively seal the sealing drawer 200.

[0036] Specifically, the guide rail plate 100 provided in this embodiment of the utility model is used to support and guide the sealed drawer 200, and at the same time to support and fix the sealed cover plate 300. The guide rail structure 120 is used to cooperate with the side wall rollers or slide grooves of the sealed drawer 200 to achieve the pulling guidance and load-bearing of the sealed drawer 200; the support structure 130 is used to provide horizontal support and height positioning for the sealed cover plate 300, and when the sealed drawer 200 is fully pushed in, the sealing structure (such as a flexible sealing strip) on the lower surface of the sealed cover plate 300 is pressed against the sealing structure (such as a ring rib) at the upper opening of the sealed drawer 200 to form a sealed preservation space.

[0037] It should be noted that the guide rail structure 120 and the support structure 130 can both be independent components, which are fixedly connected to the guide rail plate body 110 by means of snap-fit, threaded connection and other auxiliary connections, so that the guide rail structure 120, the support structure 130 and the guide rail plate body 110 form a rigid whole, so that when the inner liner 400 deforms, the three will be synchronous and offset by the same amount, ensuring the sealing effect of the sealing cover 300 on the sealing drawer 200.

[0038] In some embodiments, the guide rail plate body 110, the guide rail structure 120 and the support structure 130 can also be integrally set and manufactured by integral injection molding or other methods. They can be offset synchronously when the inner liner 400 deforms, so as to ensure that there is no relative displacement between the three, thereby maintaining the continuous sealing of the sealing cover plate 300 on the sealing drawer 200.

[0039] The guide rail structure 120 can adopt a structure with two parallel sliding grooves at the top and bottom. The mating parts (such as rollers) on the side wall of the sealed drawer 200 are embedded in the sliding grooves to achieve the pulling guide and load-bearing of the sealed drawer 200. The support structure 130 can adopt a plate-shaped recessed step surface combined with the limiting support of the surrounding enclosure. It is recessed in the upper edge area of ​​the guide rail plate body 110, and the continuous plate surface achieves horizontal load-bearing and limiting of the sealing cover 300. It has high space utilization and can maintain the overall plate structure of the guide rail plate 100.

[0040] See Figure 1 and Figure 2As shown, according to some embodiments of the present invention, the support structure 130 includes a plurality of support parts 131, which are used to support the lugs 310 of the sealing cover plate 300. The plurality of support parts 131 are spaced apart along the length direction of the guide rail plate body 110.

[0041] By setting the support structure 130 to include multiple spaced support parts 131, each support part 131 can be used to support the lugs 310 located at different positions on one side of the sealing cover plate 300, thus ensuring support stability.

[0042] Specifically, the position of the support part 131 on the guide rail plate body 110 corresponds one-to-one with the hanging ear 310 on one side of the sealing cover plate 300, that is, the multiple hanging ears 310 on one side of the sealing cover plate 300 are supported one-to-one by the support part 131.

[0043] As an example, in this embodiment, the support structure 130 includes two spaced-apart support portions 131, and the sealing cover plate 300 is provided with two corresponding lugs 310 on one side.

[0044] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, a receiving groove 132 is formed on the support portion 131, and the receiving groove 132 is used to support the hanging ear 310 of the sealing cover plate 300.

[0045] By setting the support structure 130 as a structure combining the support part 131 with the receiving groove 132, the hanging ear 310 of the sealing cover 300 can be directly sunk into the groove, realizing self-positioning in the height direction and lateral limiting within a certain range, preventing the sealing cover 300 from sliding laterally or warping during the pushing and pulling of the sealing drawer 200.

[0046] Specifically, the receiving groove 132 is formed by the downward recess of the top surface of the support part 131, and its outline is in clearance with the outer periphery of the hanging ear 310: the bottom of the groove bears all the vertical load of the hanging ear 310, realizing the self-positioning of the cover height; the groove wall can reserve a set gap in the front and rear directions to facilitate the hanging ear 310 to enter the receiving groove 132.

[0047] Understandably, in order to ensure that the lug 310 of the sealing cover 300 can smoothly enter the receiving groove 132, the width of the groove opening of the receiving groove 132 must be greater than or equal to the width of the lug 310.

[0048] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the width of the receiving groove 132 gradually increases along the direction from the opening to the bottom of the groove.

[0049] By gradually increasing the width of the receiving groove 132 from the opening to the bottom, along the direction of the groove opening of the receiving groove 132, it can be ensured that the hanging ear 310 can fall smoothly into the receiving groove 132 when it is placed in the receiving groove 132, preventing the hanging ear 310 from rubbing against the side wall of the receiving groove 132, which would cause the sealing cover plate 300 to be suspended or warped, and ensuring that the lower surface of the sealing cover plate 300 is evenly pressed and sealed with the upper opening of the sealing drawer 200 after it is in place.

[0050] Specifically, the side wall of the receiving groove 132 flares outward from the groove opening, with the net width at the groove opening slightly larger than the width of the hanging ear 310, and the net width at the bottom of the groove being the largest. When the hanging ear 310 enters, it is first guided to the center by the groove opening, and then falls into the bottom of the groove without contact. Throughout the process, the hanging ear 310 maintains a gap with the side wall, which can effectively prevent frictional resistance and upward lifting force, ensuring that the sealing cover 300 is always horizontally attached to the top of the sealing drawer 200, and the sealing height is consistent.

[0051] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the support portion 131 is disposed on the top of the guide rail plate body 110, and a first hollow groove 140 is provided between adjacent support portions 131.

[0052] By placing the support portion 131 on the top of the guide rail plate body 110, the sealing cover plate 300 hook 310 can directly rest against the highest point of the guide rail plate 100, eliminating the need for an additional lifting structure and reducing the number of parts. At the same time, the first hollow groove 140 formed between adjacent support portions 131 can reduce the weight of the guide rail plate 100, save materials, and avoid a large gap between the uppermost part of the guide rail plate 100 and the inner liner 400 wall, thus avoiding visual discontinuity and improving the internal cleanliness and aesthetics.

[0053] Specifically, the guide rail plate 100 is usually fixed to the inner liner 400 by a snap-fit ​​pre-fixation and threaded fastener installation method. After the guide rail plate 100 is fastened by the threaded fastener, there will be a certain gap between the outer area of ​​the fastener and the inner liner 400. If a solid top surface is retained between the multiple support parts 131 on the top of the guide rail plate 100, it will result in obvious gaps, affecting the cleanliness and aesthetics of the refrigerator interior.

[0054] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the guide rail plate body 110 is provided with a second hollow groove 150 for weight reduction.

[0055] By setting a second hollowed-out groove 150 on the guide rail plate body 110, the weight of the guide rail plate 100 can be further reduced and the material cost can be lowered.

[0056] It should be noted that the second perforated groove 150 can be a single hole, multiple holes, or a continuous grid of holes, etc. Its shape, size, and arrangement can be flexibly adjusted according to the weight reduction requirements and the strength requirements of the guide rail plate 100, and there are no special limitations on this. Moreover, the setting position of the second perforated groove 150 can be flexibly adjusted according to the stress distribution on the guide rail plate 100, the division of functional areas, and the clearance requirements of the inner liner 400: if it is concentrated in the non-load-bearing area, the roller avoidance area of ​​the sealed drawer 200, or the corresponding area of ​​the air duct of the inner liner 400, it can maximize weight reduction and avoid interference with the support part 131, the guide rail structure 120, and the mounting point; if the perforation is reduced or eliminated near the screw fastening position or the high bending moment area, it can maintain local rigidity, prevent the guide rail plate 100 from deforming, and ensure that the sealing cover plate 300 is always pressed smoothly.

[0057] For example, in this embodiment, the guide rail plate body 110 is provided with a second hollow groove 150 in the middle. The second hollow groove 150 extends along the length direction of the guide rail plate body 110. The guide rail structure 120 is formed on the solid plate surface below the second hollow groove 150, and the support structure 130 is formed on the solid plate surface above the second hollow groove 150.

[0058] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the guide rail plate body 110, the guide rail structure 120 and the support structure 130 are integrally formed.

[0059] By integrating the guide rail plate body 110, guide rail structure 120, and support structure 130 into a single assembly, a guide rail plate 100 with both the guide rail structure 120 and support structure 130 can be formed in one step, completely eliminating the cumulative tolerances caused by separate assembly. When the inner liner 400 undergoes thermal expansion and contraction or assembly deformation, the guide rail structure 120 and support structure 130 shift synchronously with identical shift amounts, ensuring that the sealing cover 300 always receives stable and uniform support. This fundamentally avoids localized warping or sealing failure, while also reducing the number of parts, assembly time, and costs.

[0060] The sealed drawer structure provided by this utility model is described below. The sealed drawer structure described below can be referred to in correspondence with the guide rail plate 100 described above.

[0061] See Figure 3 and Figure 4 As shown, the sealed drawer structure provided in this embodiment of the utility model includes: two guide rail plates 100, a sealed drawer 200, and a sealed cover plate 300.

[0062] Two guide rails 100 are parallel to each other and spaced apart; a sealed drawer 200 is located between the two guide rails 100, and the two sides of the sealed drawer 200 are respectively slidably engaged with the guide rail structure 120 on the corresponding side guide rail 100; the two sides of the sealed cover 300 are respectively attached to the support structure 130 on the corresponding side guide rail 100.

[0063] The sealing drawer structure provided by this utility model, due to the use of the guide rail plate 100 as described in any of the above embodiments, can also cause the guide rail structure 120 and the support structure 130 to shift synchronously and with the same amount of shift when the processing precision of the refrigerator inner liner 400 is insufficient or it is deformed. This can effectively ensure the sealing effect of the sealing cover plate 300 on the sealing drawer 200, and solve the defect that the sealing cover plate 300 of the existing refrigerator cannot effectively seal the sealing drawer 200.

[0064] Specifically, during installation, the guide rail plate 100 can be rigidly connected to the side or bottom wall of the inner liner 400 by means of pre-positioning with clips, fastening with screws, or hot riveting. The specific connection depends on the space occupied by the sealed drawer structure within the refrigerator inner liner 400.

[0065] It should be noted that the two guide rail plates 100 can be of the same or different specifications, and there are no special restrictions on this. For example, a corresponding mounting mechanism can be set according to the mounting and fixing position of the guide rail plate 100.

[0066] See Figure 5 and Figure 6 As shown, for example, when the sealed drawer structure occupies half of the horizontal space at the bottom of the inner liner 400, one guide rail plate 100 can be fixedly connected to the side wall of the refrigerator inner liner 400, and the other guide rail plate 100 can be fixedly connected to the bottom wall of the refrigerator inner liner 400 to meet the installation and fixing requirements of the sealed drawer structure.

[0067] It is understood that in some embodiments, when the sealed drawer structure occupies the entire lateral space at the bottom of the inner liner 400, the two guide rails 100 are fixedly connected to the two side walls of the refrigerator inner liner 400 respectively, so as to meet the installation and fixing requirements of the sealed drawer structure.

[0068] The refrigerator provided by this utility model is described below. The refrigerator described below can be referred to in correspondence with the guide rail plate 100 or the sealed drawer structure described above.

[0069] See Figure 5 and Figure 6 As shown, the refrigerator provided in this embodiment of the present invention includes: a guide rail plate 100 as described in any of the previous embodiments or a sealed drawer structure as described in any of the previous embodiments.

[0070] The refrigerator provided by this utility model, by adopting the guide rail plate 100 as described in any of the previous embodiments or the sealed drawer structure as described in any of the previous embodiments, can also cause the guide rail structure 120 and the support structure 130 to shift synchronously and with the same shift amount when the inner liner 400 of the refrigerator is not processed with sufficient precision or is deformed. This can effectively ensure the sealing effect of the sealing cover 300 on the sealed drawer 200, and solve the defect that the sealing cover 300 of the existing refrigerator cannot effectively seal the sealed drawer 200.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
