Description

Technical Field

[0001] This application relates to the field of refrigerator preservation technology, and more particularly to a refrigerator drawer assembly and a refrigerator. Background Technology

[0002] In existing refrigerators, the middle partition and drawer assembly work together to form a fruit and vegetable preservation cavity. The middle partition is fixed, while the drawer assembly needs to be able to slide out and push back for easy access to fruits and vegetables. To improve the sealing of the preservation cavity, some refrigerators add a refrigerator cover between the middle partition and the drawer assembly. The refrigerator cover closes with the drawer assembly to improve the sealing performance of the preservation cavity. However, since there is still a relative movement requirement between the refrigerator cover and the drawer assembly, they often need to be sealed on multiple planes. Each plane must be precisely fitted and sealed to ensure the overall sealing of the preservation cavity. However, this method of "precise fitting and sealing of each plane" not only requires high precision but is also difficult to achieve in practical applications, resulting in reduced preservation performance due to poor sealing in actual use. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a refrigerator drawer assembly to solve the problem of poor sealing of the preservation cavity in existing refrigerators.

[0004] This application also proposes a refrigerator.

[0005] According to a first aspect embodiment of the present application, a refrigerator drawer assembly includes: The guide rail is equipped with a limit groove; A refrigerator cover includes a cover body and hanging ears connected to both sides of the cover body, wherein the hanging ears are installed in the limiting groove; A drawer is mounted on the guide rail and can slide relative to the guide rail to switch between an open position and a closed position; the drawer has a top opening and the top ends of the side panels surrounding the top opening are located on the same plane; in the closed position, the refrigerator lid closes onto the plane to form a closed cavity with the drawer.

[0006] According to one embodiment of this application, the drawer includes a drawer body and a panel connected to the front end of the drawer body, wherein the drawer body and the panel are integral components.

[0007] According to one embodiment of this application, the top of the panel is provided with a handle groove, which is formed by the cooperation of a parallel first side plate and a second side plate. The first side plate is located on the side of the handle groove near the rear of the drawer, and the second side plate is located on the side of the handle groove near the front of the drawer. The side panel that forms the top opening includes the first side panel; The top ends of each side plate forming the top opening are located on the same plane as the top end of the second side plate, or the top end of the second side plate is higher than the top ends of each side plate forming the top opening.

[0008] According to one embodiment of this application, in the open position, the hook abuts against the contact surface of the limiting groove to support the refrigerator lid; in the closed position, a reserved gap is formed between the contact surface and the hook to allow the drawer to support the refrigerator lid.

[0009] According to one embodiment of this application, the upper surface of the drawer that mates with the refrigerator cover includes a first inclined surface, and the lower surface of the refrigerator cover that mates with the drawer includes a second inclined surface, wherein the first inclined surface and the second inclined surface are adapted to each other. Both the first inclined surface and the second inclined surface are inclined along the front-to-back direction of the refrigerator.

[0010] According to one embodiment of this application, the tilt angles of the first tilted surface and the second tilted surface are both greater than or equal to 2° and less than or equal to 3°.

[0011] According to one embodiment of this application, the limiting groove has a communicating upper opening and a side opening, and the hook extends into the limiting groove through the side opening.

[0012] According to one embodiment of this application, the length direction of the upper opening is the same as the front-rear direction of the refrigerator; The length of the upper opening is less than the length of the contact surface of the limiting groove, so as to prevent the hanging ear from coming out of the limiting groove.

[0013] According to one embodiment of this application, the sidewall of the limiting groove is an inclined surface, and the inclined surface gradually moves away from the hanging ear in a downward direction.

[0014] A refrigerator according to a second aspect of this application includes the aforementioned refrigerator drawer assembly.

[0015] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects: This application proposes a refrigerator drawer assembly in which the top opening of the drawer is formed by the tops of each side panel, and the tops of each side panel are located on the same plane. The refrigerator cover is closed on this plane to form a closed cavity. The contact points between the refrigerator cover and the drawer are all located on the same plane. The sealing performance of the closed cavity can be guaranteed by the lower surface of the refrigerator cover and the upper surface of the drawer being tightly fastened together. There is no need for a sealing position where "the front end of the refrigerator cover abuts against the side wall of the panel". This reduces the difficulty of sealing between the refrigerator cover and the drawer and improves the preservation performance of the closed cavity.

[0016] Furthermore, when the drawer is in the closed position, a pre-existing gap is formed between the contact surface and the hanging lugs. The refrigerator lid, relying on its own weight, presses directly against the top opening of the drawer, eliminating any potential gaps between them and significantly improving the sealing performance of the enclosed cavity. Good sealing reduces airflow inside and outside the cavity, maintaining a suitable humidity and temperature environment within the cavity, slowing down the rate of moisture loss and oxidation of fruits and vegetables, thereby improving preservation.

[0038] A refrigerator drawer assembly according to an embodiment of the first aspect of this application, such as Figure 1 and Figure 2 As shown, the refrigerator drawer assembly includes a guide rail 1, a refrigerator cover 2, and a drawer 3. The guide rail 1 has a limiting groove 11. The refrigerator cover 2 includes a cover body 21 and hooks 22 connected to both sides of the cover body 21, with the hooks 22 installed in the limiting groove 11. The drawer 3 is mounted on the guide rail 1 and can slide relative to the guide rail 1 to switch between an open and closed position. The drawer 3 has a top opening 31, and the tops of the side panels surrounding the top opening 31 are located on the same plane 32. In the closed position, the refrigerator cover 2 closes onto the plane 32 to form a closed cavity with the drawer 3. This plane 32 forms the upper surface on which the drawer 3 mates with the refrigerator cover 2.

[0039] It should be noted that the refrigerator cover 2 in this embodiment is not the middle partition in a traditional refrigerator. In other words, when the refrigerator cover 2 in this embodiment is applied to a refrigerator, there is still a middle partition inside the refrigerator. The refrigerator cover 2 is located between the middle partition and the drawer 3 and is used solely to cover the drawer 3. The middle partition only serves to place items.

[0040] The refrigerator drawer assembly forms a closed cavity by placing the tops of the side panels surrounding the top opening 31 of the drawer 3 on the same plane 32. The refrigerator cover 2 then closes onto this plane 32. Since the contact points between the refrigerator cover 2 and the drawer 3 are concentrated on the same plane, a tight seal is achieved simply by ensuring a tight fit between the contact surfaces. This design reduces the number of sealing points, avoiding the additional sealing requirement of "the front end of the refrigerator cover 2 abutting against the side wall of the panel 35" in traditional structures. This effectively reduces the design difficulty and assembly precision requirements of the sealing structure, while improving the sealing stability of the closed cavity and contributing to the optimization of food preservation performance.

[0041] The limiting groove 11 of the guide rail 1 cooperates with the hanging lug 22 of the refrigerator cover 2, providing a stable installation benchmark for the refrigerator cover 2, ensuring that the refrigerator cover 2 will not shift or loosen during use, and further guaranteeing the continuity of the sealing effect. The drawer 3 can slide relative to the guide rail 1 to switch between the open and closed positions. Combined with the precise closing structure of the cover and drawer 3, the opening and closing operation of the drawer 3 is smooth and reliable. This simplifies the overall structure of the components, reduces the cooperation conflicts between parts, and reduces the complexity of the manufacturing process, which is conducive to controlling production costs. The connection method of each component is simple and clear, the assembly process is convenient, and subsequent maintenance or replacement of parts is easier to operate, improving the product's ease of use and durability.

[0042] According to one embodiment of this application, such as Figures 3 to 5 As shown, in the open position, the hanging ear 22 abuts against the abutting surface 111 of the limiting groove 11 to support the refrigerator cover 2; in the closed position, a reserved gap 112 is formed between the abutting surface 111 and the hanging ear 22 so that the drawer 3 supports the refrigerator cover 2.

[0043] When drawer 3 slides from the closed position to the open position, the lug 22 is always kept within the limiting groove 11, so that the refrigerator cover 2 remains in the original position and does not move with drawer 3. This avoids the problem of the cover shifting and causing it to be unable to close accurately later. It ensures that after drawer 3 is put back into position, it can quickly form a closed cavity with the refrigerator cover 2, providing basic conditions for the preservation of fruits and vegetables.

[0044] In the vertical direction, the support method of the limiting groove 11 dynamically adjusts with the position of the drawer 3, creating a differentiated support effect. When the drawer 3 is in the open position, the hook 22 abuts against the abutting surface 111 of the limiting groove 11, providing stable support for the refrigerator cover 2 and preventing the cover from shaking or falling off due to the loss of drawer 3 support, thus improving structural stability during use. When the drawer 3 is in the closed position, a reserved gap 112 is formed between the abutting surface 111 and the hook 22, and the refrigerator cover 2 presses directly against the top opening 31 of the drawer 3 by its own weight, eliminating any possible gaps between them and significantly improving the sealing performance of the enclosed cavity. Good sealing performance can reduce air circulation inside and outside the cavity, maintain a suitable humidity and temperature environment inside the cavity, slow down the rate of moisture loss and oxidation of fruits and vegetables, and thus improve the preservation effect. At the same time, this dynamic support structure not only ensures the smoothness of the drawer 3's pulling process, but also avoids the sealing gap problem that may be caused by fixed support, achieving an optimized balance between structural stability and sealing performance.

[0045] Furthermore, the dynamic adjustment of the support method of the limiting groove 11 according to the position of the drawer 3 effectively reduces the distance traveled by the drawer 3 to rub against the refrigerator cover 2. When the drawer 3 is in the closed position, the refrigerator cover 2 is pressed against the top opening 31 of the drawer 3 by its own weight, and the two are in a close contact state. When the drawer 3 begins to be pulled outward, as the drawer 3 moves, the hook 22 gradually approaches the abutment surface 111 of the limiting groove 11 (approaching in the height direction, remaining stationary in the front-back direction). After the hook 22 contacts the abutment surface 111, the refrigerator cover 2 is supported by the limiting groove 11 and remains in its original position, at which point the drawer 3 and the refrigerator cover 2 are no longer in contact. As the drawer 3 continues to slide outward to the open position, the drawer 3 and the refrigerator cover 2 remain separated, with no friction generated. Similarly, when drawer 3 returns to the closed position from the open position, the refrigerator cover 2 is always supported by the limiting groove 11 and remains separate from drawer 3 until drawer 3 is fully returned to its original position. Only when drawer 3 is about to reach the closed position does the hanging ear 22 form a reserved gap 112 with the abutting surface 111 of the limiting groove 11, and the refrigerator cover 2 then re-fits the drawer 3.

[0046] The limiting groove 11's support mechanism dynamically adjusts with the position of drawer 3, ensuring that friction between drawer 3 and refrigerator cover 2 occurs only within a short distance as drawer 3 approaches or just begins to open, significantly reducing the frictional contact distance. Reducing the frictional distance not only decreases wear on the contact areas between drawer 3 and refrigerator cover 2, preventing edge deformation and paint peeling caused by long-term friction and extending the lifespan of components, but also reduces noise generated during friction, improving the smoothness of drawer 3's operation and the quietness of the user experience. Simultaneously, reducing component wear due to friction prevents a decrease in fitting precision caused by wear, ensuring a good fit between refrigerator cover 2 and drawer 3 over the long term, maintaining the stability of the sealed cavity's sealing performance, and providing a continuous and reliable environment for preserving fruits and vegetables.

[0047] In some cases, an elastic buffer layer can be added to the contact surface 111 of the limiting groove 11. This buffer layer can be made of flexible materials such as silicone or rubber. When the drawer 3 is opened, the buffer layer absorbs the impact force when the hook 22 contacts the contact surface 111, reducing the noise generated by the collision. At the same time, it avoids rigid wear between the hook 22 and the limiting groove 11, extending the service life of the components and improving the comfort of the user experience. In addition, an annular sealing protrusion can be provided on the lower edge of the refrigerator cover 2. The sealing protrusion is made of an elastic material and matches the edge contour of the top opening 31 of the drawer 3. When the drawer 3 is closed, the sealing protrusion fits tightly against the edge of the top opening 31 of the drawer 3, further enhancing the sealing effect on the basis of its own weight, reducing the leakage of cold air inside the cavity and the infiltration of external humid and hot air.

[0048] According to one embodiment of this application, such as Figures 6 to 8 As shown, the upper surface of the drawer 3 that mates with the refrigerator cover 2 includes a first inclined surface 33, and the lower surface of the refrigerator cover 2 that mates with the drawer 3 includes a second inclined surface 23. The end of the inclined surface (first inclined surface 33 and second inclined surface 23) near the front of the refrigerator is higher than the end of the inclined surface near the rear of the refrigerator. Figure 6 The front and rear of the refrigerator are shown. The first inclined surface 33 and the second inclined surface 23 are adapted to each other; both the first inclined surface 33 and the second inclined surface 23 are inclined in the front-to-back direction of the refrigerator.

[0049] The first inclined surface 33 and the second inclined surface 23 are inclined along the front-to-back direction of the refrigerator and are adapted to each other, providing precise guidance for the pull-out action of the drawer 3. When the drawer 3 returns to the closed position from the open position, the two inclined surfaces contact and form a sliding fit. Using the guiding force generated by the inclined angle, the drawer 3 is guided to return to its correct position, avoiding deviation or misalignment of the drawer 3 during the closing process and improving the smoothness of operation.

[0050] The structural characteristics of the inclined surface can work synergistically with the weight of the refrigerator cover 2. When the drawer 3 is closed, the second inclined surface 23 of the refrigerator cover 2 will slide down naturally along the first inclined surface 33, achieving a tight seal under the action of gravity. A good sealing effect can be achieved without applying additional pressure, reducing the difficulty of operation and improving the ease of use.

[0051] According to one embodiment of this application, such as Figure 8 As shown, the inclination angle α of the first inclined surface 33 and the second inclined surface 23 is greater than or equal to 2° and less than or equal to 3°. Here, the reference plane for the inclination angle α is the horizontal plane. In other words, the angle between the first inclined surface 33 and the horizontal plane forms the aforementioned inclination angle. Similarly, the angle between the second inclined surface 23 and the horizontal plane forms the aforementioned inclination angle.

[0052] The tilt angles of the first tilting surface 33 and the second tilting surface 23 are limited to between 2° and 3°, ensuring the effectiveness of the guiding function while avoiding usage defects caused by excessively large or small angles. This angle range provides sufficient guiding force. When the drawer 3 is pulled out or reset, the two tilting surfaces can form a precise sliding guide through the appropriate tilt angle, guiding the drawer 3 to move smoothly along the preset trajectory, effectively preventing the drawer 3 from shifting or misaligning. This ensures that the drawer 3 can quickly and accurately align and close with the refrigerator lid 2, improving the convenience and smoothness of operation. At the same time, the appropriate tilt angle will not significantly increase the frictional resistance when the drawer 3 is pulled out, avoiding the problems of difficulty in pulling out due to excessive angle or insufficient guiding force and inability to achieve effective positioning due to insufficient angle.

[0053] For example, the inclination angle of the first inclined surface 33 and the second inclined surface 23 can be 3°.

[0054] According to one embodiment of this application, such as Figure 5 As shown, the limiting groove 11 has a communicating upper opening 113 and a side opening 114, and the hanging ear 22 extends into the limiting groove 11 through the side opening 114.

[0055] Both the first and second sidewalls can be set as inclined surfaces, and gradually move away from the hanging ear 22 in a downward direction to avoid rigid collision or jamming between the hanging ear 22 and the sidewall 115.

[0056] When drawer 3 switches between the open and closed positions, the hanging ear 22 moves up and down with the height change of the refrigerator cover 2. The slanted structure guides the hanging ear 22 to smoothly complete the position change, preventing the movement from being blocked by the side wall 115. This ensures that the refrigerator cover 2 can fall normally during the drawer 3's operation, while also ensuring the continuity and smoothness of the drawer's movement, thus improving the user experience. At the same time, the slanted structure reduces the contact area between the hanging ear 22 and the side wall 115, reducing frictional wear and extending the service life of the hanging ear 22 and the limiting groove 11.

[0057] In some cases, a low-friction coefficient coating can be sprayed onto the side wall 115 surface of the limiting groove 11. The coating material can be polytetrafluoroethylene or ceramic coating to further reduce the frictional resistance between the hanging ear 22 and the inclined surface, making the up-and-down movement of the hanging ear 22 smoother, while enhancing the wear resistance and corrosion resistance of the inclined surface, reducing wear and deformation after long-term use, extending the service life of the component, and adapting to high-frequency pull-out scenarios.

[0058] According to one embodiment of this application, such as Figure 5 As shown, the length direction of the upper opening 113 is the same as the front and back direction of the refrigerator; the length of the upper opening 113 is less than the length of the contact surface 111 of the limiting groove 11, so as to restrict the hanging ear 22 from coming out of the limiting groove 11.

[0059] like Figure 5 As shown, L1 is the height direction of the limiting groove 11, L2 is the length direction of the upper opening 113, and L3 is the width direction of the upper opening 113.

[0060] The length of the upper opening 113 is consistent with the front and back direction of the refrigerator, which is adapted to the movement trajectory of the hanging ear 22 as the drawer 3 is pulled out. The hanging ear 22 can move slightly in the front and back direction within the limiting groove 11 to avoid the hanging ear 22 getting stuck in the limiting groove 11, and to ensure that the refrigerator cover 2 can fall normally so that the hanging ear 22 contacts the contact surface 111.

[0061] The length of the upper opening 113 is less than the length of the abutment surface 111 of the limiting groove 11, which effectively avoids the risk that the hanging ear 22 of the refrigerator cover 2 will come off from the upper opening 113 when the drawer 3 is pulled out, ensuring the installation stability of the refrigerator cover 2, and thus ensuring that the sealing performance of the closed cavity is not affected.

[0062] According to one embodiment of this application, such as Figure 5 As shown, the side wall 115 of the limiting groove 11 is an inclined surface, which gradually moves away from the hanging ear 22 in a downward direction.

[0063] For example, the limiting groove 11 has an upper opening 113 and a side opening 114. The limiting groove 11 may have three side walls 115, including two first side walls on both sides along the extension direction of the lug 22, and a second side wall opposite to the side opening 114. Both the first and second side walls may be set as inclined surfaces and gradually move away from the lug 22 in a downward direction to avoid rigid collision or jamming between the lug 22 and the side wall 115.

[0064] When drawer 3 switches between the open and closed positions, the hanging ear 22 moves up and down with the height change of the refrigerator cover 2. The slanted structure guides the hanging ear 22 to smoothly complete the position change, preventing the movement from being blocked by the side wall 115. This ensures that the refrigerator cover 2 can fall normally during the drawer 3's operation, while also ensuring the continuity and smoothness of the drawer's movement, thus improving the user experience. At the same time, the slanted structure reduces the contact area between the hanging ear 22 and the side wall 115, reducing frictional wear and extending the service life of the hanging ear 22 and the limiting groove 11.

[0065] In some cases, a low-friction coefficient coating can be sprayed onto the side wall 115 surface of the limiting groove 11. The coating material can be polytetrafluoroethylene or ceramic coating to further reduce the frictional resistance between the hanging ear 22 and the inclined surface, making the up-and-down movement of the hanging ear 22 smoother, while enhancing the wear resistance and corrosion resistance of the inclined surface, reducing wear and deformation after long-term use, extending the service life of the component, and adapting to high-frequency pull-out scenarios.

[0066] According to one embodiment of this application, such as Figure 10 and Figure 11 As shown, the refrigerator drawer assembly also includes a cushioning sleeve 4 fitted around the outer periphery of the hanging lug 22.

[0067] The buffer sleeve 4 is fitted around the outer periphery of the hanging ear 22, effectively absorbing the impact force between the hanging ear 22 and the limiting groove 11, reducing noise generated by their rigid contact. When the drawer 3 is pulled out, causing the hanging ear 22 to move within the limiting groove 11 or come into contact with the contact surface 111, the buffer sleeve 4 cushions the instantaneous force through its own elastic deformation, preventing the hanging ear 22 from directly colliding with the wall of the limiting groove 11 and generating abnormal noise, thus improving the quietness of the refrigerator during use. At the same time, the elastic properties of the buffer sleeve 4 can alleviate the impact force on the hanging ear 22, reduce the risk of deformation of components due to impact, and ensure structural stability.

[0068] The buffer sleeve 4 can form a flexible isolation layer between the lug 22 and the limiting groove 11, reducing wear caused by the relative movement of the two, protecting the main structure of the lug 22 and the limiting groove 11, and extending their service life.

[0069] According to one embodiment of this application, the reserved gap 112 is greater than 0 mm and less than or equal to 1.5 mm.

[0070] The reserved gap 112 is limited to a range greater than 0 mm and less than or equal to 1.5 mm, which can accurately achieve a smooth switching between the supporting function of the limiting groove 11 and the sealing function of the refrigerator cover 2. When the drawer 3 returns to the closed position from the open position, the hook 22 gradually disengages from the abutment surface 111 of the limiting groove 11. The reserved gap 112 provides reasonable falling space for the refrigerator cover 2, allowing the cover to be steadily pressed against the top opening 31 of the drawer 3 by its own weight. This avoids collision noise caused by excessive falling distance due to excessive gap, or gaps that cannot be fully fitted and leave gaps due to insufficient gap. This gap range allows the fitting action of the cover and drawer 3 to be smoother, while ensuring that there are no obvious gaps after fitting, providing a basic guarantee for the sealing performance of the closed cavity.

[0071] Furthermore, the reserved gap 112 in the aforementioned range can not only accommodate the dimensional errors during the manufacturing stage of the refrigerator cover 2, but also compensate for the plastic deformation that may occur during the life cycle of the refrigerator cover 2.

[0072] For example, the reserved gap 112 can be 1 mm.

[0073] According to one embodiment of this application, such as Figure 9 and Figure 10 As shown, two hanging ears 22 are provided on each side of the cover plate body 21, and the number of limiting grooves 11 is adapted to the number of hanging ears 22.

[0074] Two hanging ears 22 are provided on each side of the main body 21 of the refrigerator cover, which, together with a suitable number of limiting grooves 11, form a four-point uniform support structure, improving the installation stability of the refrigerator cover 2. The four hanging ears 22 respectively cooperate with the corresponding limiting grooves 11, providing all-round constraint on the refrigerator cover 2 from both sides and front and back, preventing the cover from tilting or wobbling during the pulling out of the drawer 3, ensuring that the cover always maintains a horizontal posture, and providing a structural basis for the precise fit between the drawer 3 and the cover after closing. The multi-point support layout can also distribute the weight and force of the cover, avoiding deformation or damage caused by excessive pressure on a single hanging ear 22, and extending the service life of the cover and the hanging ears 22.

[0075] The four-point mating structure significantly improves guiding accuracy and reduces displacement deviation of the refrigerator cover 2. Each lug 22 and its corresponding limiting groove 11 form an independent guiding unit. The four units work together to effectively limit the offset of the cover and ensure that the cover remains in its original position when the drawer 3 is pulled out.

[0076] According to one embodiment of this application, such as Figure 12 As shown, drawer 3 includes drawer body 34 and panel 35 connected to the front end of drawer body 34. Drawer body 34 and panel 35 are integral components.

[0077] The drawer body 34 and the panel 35 adopt a one-piece component design, directly eliminating the assembly process between the two. This avoids positioning deviations caused by assembly operations in a split structure, ensuring the relative positional accuracy of the panel 35 and the drawer body 34. This makes the drawer 3 slide more smoothly on the guide rail 1, reducing jamming or friction noise caused by positional misalignment. The structure of the guide rail 1 that mates with the drawer 3 is as follows: Figure 9 As shown.

[0078] The integrated structure eliminates the need for additional fasteners or connecting structures, which not only simplifies the product's component composition and reduces the complexity of material management and production assembly, but also avoids problems such as loosening and detachment of connecting parts that occur after long-term use in a split structure, thereby improving the overall structural strength and durability of drawer 3.

[0079] Furthermore, the integrated drawer structure 3 eliminates gaps at the connection between the drawer body 34 and the panel 35, further improving the sealing of the enclosed cavity and ensuring its food preservation performance.

[0080] Of course, in some embodiments, the drawer body 34 and the panel 35 may also adopt a non-integrated structure, such as snap-fit ​​connection, screw connection, magnetic connection, etc.

[0081] According to one embodiment of this application, such as Figure 12 and Figure 13 As shown, a handle groove 351 is provided on the top of the panel 35. The handle groove 351 is formed by the cooperation of a parallel first side plate 352 and a second side plate 353. The first side plate 352 is located on the side of the handle groove 351 near the rear of the drawer 3, and the second side plate 353 is located on the side of the handle groove 351 near the front of the drawer 3. The side plate surrounding the top opening 31 includes the first side plate 352. The top of each side plate surrounding the top opening 31 and the top of the second side plate 353 are located on the same plane 32, or the top of the second side plate 353 is higher than the top of each side plate surrounding the top opening 31.

[0082] The handle groove 351 is formed by the cooperation of the parallel first side plate 352 and the second side plate 353, providing a clear force application point for the drawer 3 to be pulled out. Users can easily switch the drawer 3 between the open and closed positions by holding the handle groove 351, improving operational comfort. The first side plate 352, as one of the side plates surrounding the top opening 31 of the drawer 3, organically integrates the structure of the handle groove 351 with the surrounding structure of the top opening 31 of the drawer 3. There is no need to set a separate handle component on the drawer 3 or the panel 35, simplifying the overall structural design of the drawer 3, reducing the number of parts, and lowering manufacturing and assembly costs. At the same time, the first side plate 352 maintains a coordinated position with the tops of the other side plates surrounding the top opening 31, ensuring the integrity of the top opening 31 of the drawer 3, providing a flat and continuous fit for the closing of the refrigerator lid 2, and contributing to the stable performance of the sealing.

[0083] The tops of the side panels forming the top opening 31 and the top of the second side panel 353 are arranged in two ways: either "on the same plane" or "the top of the second side panel 353 is higher," to adapt to different usage needs and appearance design concepts. When both are on the same plane, the top of the second side panel 353 is relatively low, providing a better grip experience for the user. When the top of the second side panel 353 is higher than the tops of the other side panels, it can effectively cover and shield the connecting parts of the components inside the drawer 3 or the top edge of the side panels, reducing the exposure of the internal structure, improving the cleanliness and aesthetics of the refrigerator drawer components, and preventing external dust and debris from directly entering the interior of the drawer 3 or the gaps between the components, thus providing a certain degree of protection for the internal components and extending their service life.

[0084] A refrigerator according to a second aspect of this application includes the aforementioned refrigerator drawer assembly.

[0085] The refrigerator integrates the aforementioned refrigerator drawer assembly, continuing the advantages of its sealing structure. The same plane 32 formed by the top of each side panel of drawer 3 precisely covers the refrigerator cover 2, reducing sealing points and simplifying the sealing process. This ensures the sealing performance of the refrigerator's internal enclosed cavity, effectively reducing cold air loss, slowing down food moisture evaporation and spoilage, and improving the overall freshness preservation capability of the refrigerator. Drawer 3 can slide smoothly relative to the guide rail 1, and the handle groove 351 on the top of the panel 35 provides users with a convenient operating experience for taking out and putting in food.

[0086] By integrating a simple, modular refrigerator drawer assembly, the refrigerator simplifies its internal assembly process, reduces assembly errors caused by numerous parts, and improves the stability and efficiency of the refrigerator production process. The exterior design of the drawer assembly (such as the height adjustment of the top of the second side panel 353) harmonizes with the overall appearance of the refrigerator, avoiding visual conflicts between internal components and the refrigerator liner, door, and other structures, thus enhancing the overall aesthetics and texture of the refrigerator. Simultaneously, the drawer assembly achieves sealing and protection functions without the need for additional complex auxiliary components, allowing the refrigerator to maintain core performance without significantly increasing production costs. This balances practicality and economy, meeting the comprehensive needs of different users for refrigerator preservation, ease of operation, and aesthetics.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
