[0037] With the improvement of living standards, users have higher and higher requirements for the moisturizing of refrigeration equipment such as refrigerators. In the existing structure, in order to facilitate users to open the drawer easily, the gap between the cover and the drawer is usually set to be larger, generally around 4 mm. Due to the large gap, cold air is easily lost, affecting the moisturizing effect of the food in the drawer.

[0038] The embodiments of this application refer to Figure 1-Figure 3 As shown, a drawer assembly and a refrigeration device are provided.

[0039] According to one embodiment of the present application, Figure 1As shown, the drawer assembly of the embodiment of the present application includes a guide rail seat 100, a drawer body 200 and a cover body 300. The drawer body 200 is slidably arranged on the guide rail seat 100. The drawer body 200 can form a receiving space with an opening. The cover body 300 is covered on the drawer body 200. The cover body 300 has a first sealing surface 310 facing the drawer body 200. The sliding direction of the drawer body 200 and the first sealing surface 310 form a preset angle A, and the drawer body 200 is suitable for sliding to switch between an open state and a closed state. In the closed state, the drawer body 200 and the cover body 300 have a first gap. In the open state, the drawer body 200 and the cover body 300 have a second gap, and the first gap is smaller than the second gap.

[0040] It is understood that the guide rail base 100 is a fixed part of the drawer assembly and can be installed inside a refrigerator, cabinet, or other equipment that requires drawer storage function to guide and support the sliding movement of the drawer body 200. The guide rail base 100 can be designed to include a series of parallel rails or grooves that match the rollers 220 or sliders of the drawer body 200 to ensure that the drawer body 200 can slide smoothly and steadily in a specific direction.

[0041] The drawer body 200 is the main body of the drawer assembly, used to accommodate and store items. It is slidably mounted on the guide rail base 100, and the sliding function is achieved through the cooperation of the guide rail 210 and the guide rail base 100. The drawer body 200 has an opening at the top, which allows the user to access the storage space inside. The drawer body 200 can slide relative to the guide rail base 100 to move between an open state and a closed state. The cover 300 is a component installed above the opening of the drawer body 200 and is used to seal the opening of the drawer body 200, preventing the loss of cold air and protecting the items inside the drawer body 200.

[0042] In this embodiment, by setting a preset angle A between the sliding direction of the drawer body 200 and the first sealing surface 310, and the preset angle A being greater than 0 degrees, the position of the drawer body 200 relative to the cover 300 will change during the sliding process of the drawer body 200, thereby causing the gap between the two to change accordingly. Specifically, when the drawer body 200 slides from the closed state to the open state, due to the presence of the preset angle, the gap between the drawer body 200 and the cover 300 will gradually increase, ensuring that the drawer body 200 can open smoothly; and when the drawer body 200 slides from the open state to the closed state, the gap will gradually decrease. This design helps to ensure that the gap between the drawer body 200 and the cover 300 is smaller in the closed state, achieving a tighter seal, thereby improving the moisturizing effect of the drawer.

[0043] Since the first gap between the drawer body 200 and the cover body 300 is effectively reduced in the closed state, the possibility of cold air leakage from the inside of the drawer is reduced. This is especially important for food that needs to maintain a certain humidity (such as fruits and vegetables, meat, etc.), which helps to extend the shelf life of the food and maintain its freshness and taste.

[0044] In an optional embodiment, in the open state, the second gap between the drawer body 200 and the cover body 300 is 4 mm, and in the closed state, the first gap between the drawer body 200 and the cover body 300 is 1.5-2.5 mm. For example, the second gap is 2 mm. Compared with the existing gap between the drawer body 200 and the cover body 300 being constant at 4 mm, the moisturizing effect of the drawer can be greatly improved.

[0045] According to one embodiment of the present application, referring to Figure 1-Figure 2 As shown, the guide rail seat 100 is provided with a slide groove 110 , and guide rails 210 are provided on both sides of the drawer body 200 , and the guide rails 210 are slidably provided in the slide groove 110 .

[0046] It will be appreciated that in this embodiment, as the fixed portion of the drawer assembly, the guide rail base 100 is installed in a desired location (such as inside a refrigerator, cabinet, etc.). Slide grooves 110 are provided on the guide rail base 100. These slide grooves 110 provide precise guidance and support for the sliding of the drawer body 200. When the user needs to open or close the drawer, they only need to gently push or pull the drawer body 200. At this time, the guide rails 210 on both sides of the drawer body 200 will slide along the slide grooves 110 on the guide rail base 100, driving the drawer to move smoothly. Due to the precise fit between the guide rails 210 and the slide grooves 110 and the smooth sliding mechanism, the drawer will hardly wobble, deflect, or jam during opening and closing.

[0047] According to one embodiment of the present application, referring to Figure 1-Figure 2 As shown, the guide rail 210 is installed with a roller 220, and the slide groove 110 includes a first groove surface 111 and a second groove surface 112 arranged opposite to each other. In the closed state, the roller 220 abuts against the second groove surface 112, and there is a gap between the roller 220 and the first groove surface 111.

[0048] It can be understood that in this embodiment, rollers 220 are installed on the guide rail 210. These rollers 220 can be rolling bearings, balls or other forms of rolling elements. They can reduce the friction between the guide rail 210 and the slide groove 110 and improve the smoothness and efficiency of sliding.

[0049] The chute 110 includes a first groove surface 111 and a second groove surface 112 that are arranged opposite each other. The first groove surface 111 is generally located above the chute 110. When the drawer is closed, a certain gap is maintained between the roller 220 and the first groove surface 111 to reduce unnecessary contact and friction. The second groove surface 112 is located below the chute 110. When the drawer is closed, the roller 220 abuts against the second groove surface 112 to provide stable support and positioning.

[0050] For example, the number and distribution of the rollers 220 may be designed according to the size, weight, and usage requirements of the drawer to ensure the stability and balance of the drawer during the sliding process, which is not specifically limited in this embodiment.

[0051] According to one embodiment of the present application, referring to Figure 1-Figure 2 As shown, the first groove surface 111 and the second groove surface 112 are inclined surfaces, and the first groove surface 111 is parallel to the second groove surface 112 .

[0052] It can be understood that in this embodiment, since the first groove surface 111 and the second groove surface 112 are inclined surfaces, when the drawer body 200 is sliding, its own gravity will generate a component force along the direction of the inclined surface. This component force will act as a booster when the drawer body 200 slides downward (i.e., in the closing direction), helping the drawer to close more smoothly.

[0053] In traditional drawer designs, the user must rely entirely on their own strength to overcome the friction between the drawer body 200 and the slide 110, as well as the drawer's own inertia, in order to push the drawer body 200 into the closed state. However, in this embodiment, because the thrust generated by gravity acts as an auxiliary force, the thrust required by the user is significantly reduced, making closing the drawer easier and more labor-saving. Reducing the user's thrust not only makes the drawer closing operation more convenient, but also reduces the user's fatigue during operation.

[0054] Furthermore, the first groove surface 111 and the second groove surface 112 are parallel to each other, thereby preventing the roller 220 from getting stuck during the rolling process and ensuring smooth sliding of the drawer assembly.

[0055] According to one embodiment of the present application, referring to Figure 1-Figure 3 As shown, the guide rail seat 100 is provided with a limiting boss 120, and the guide rail 210 is provided with a first limiting portion 211. In the open state, the first limiting portion 211 abuts against the limiting boss 120; and / or, the guide rail 210 is provided with a second limiting portion 212. In the closed state, the second limiting portion 212 abuts against the limiting boss 120.

[0056] As will be appreciated, the guide rail base 100 is provided with a limiting boss 120. This boss 120 is a raised structure that cooperates with the limiting portion on the guide rail 210 to limit the drawer's sliding range. The position and size of the limiting boss 120 are designed based on the drawer's travel and the position to be limited, ensuring that the drawer is stably positioned in both the open and closed states.

[0057] In an optional embodiment, the guide rail 210 is provided with a first stopper 211, which is the portion that cooperates with the stopper boss 120 when the drawer is in the open state. When the drawer slides to the maximum open position, i.e., the open state, the first stopper 211 abuts against the stopper boss 120, thereby preventing the drawer from sliding further outward.

[0058] In another optional embodiment, the guide rail 210 may optionally be provided with a second stopper 212. This stopper mates with the stopper boss 120 when the drawer is closed. When the drawer slides to the closed position, the second stopper 212 abuts against the stopper boss 120, ensuring that the drawer remains stably closed.

[0059] The cooperation between the limiting boss 120 and the limiting portion realizes the precise control of the opening and closing state of the drawer, avoids the over-opening or under-closing of the drawer body 200 during the sliding process, and ensures the stability and safety of the drawer body 200.

[0060] According to one embodiment of the present application, referring to Figure 1-Figure 2 As shown, in the closed state, there is a first gap between the drawer body 200 and the cover 300, and a third gap between the roller 220 and the first groove surface 111, and the first gap is greater than or equal to the third gap.

[0061] It is understood that in this embodiment, as the drawer body 200 slides open, the gap between the drawer body 200 and the lid 300 gradually increases. As the drawer body 200 continues to slide, due to the shift in the center of gravity of the drawer body 200, the drawer body 200 rotates relative to the limiting boss 120 with the limiting boss 120 as a fulcrum, causing the roller 220 on the guide rail 210 to contact the first groove surface 111. At this time, as the drawer body 200 continues to be pulled open, the roller 220 abuts against the first groove surface 111 and rolls along the first groove surface 111. Because the first gap is greater than or equal to the third gap, a certain gap still exists between the drawer body 200 and the lid 300 when the roller 220 abuts against the first groove surface 111. This prevents the drawer body 200 from contacting the lid 300 during the opening process, thereby preventing the user from opening the drawer body 200 due to contact between the drawer body 200 and the lid 300. It also prevents the surface of the lid 300 from being scratched or damaged due to friction.

[0062] In this embodiment, the drawer opening process is roughly divided into the following stages:

[0063] Initial stage: When the drawer body 200 begins to be pulled, due to the tilting and sliding of the drawer body 200, the first gap between the drawer body 200 and the cover body 300 will gradually increase. This increased gap provides space for further opening of the drawer and reduces the friction between the drawer body 200 and the cover body 300.

[0064] Center of Gravity Movement and Rotation: As the drawer body 200 continues to be pulled, its center of gravity will also shift. At this point, the drawer body 200 will rotate relative to the stop boss 120, using the stop boss 120 as the fulcrum (rotation center). This rotation is natural and is determined by the drawer's gravity distribution and the sliding direction.

[0065] Contact between the roller 220 and the first groove surface 111: During the rotation of the drawer body 200, the roller 220 on the guide rail 210 will gradually come into contact with the first groove surface 111. The design of the roller 220 enables them to roll smoothly along the first groove surface 111, thereby further reducing friction and resistance, making the drawer opening process easier.

[0066] Gap maintenance: Since the first gap is ensured to be greater than or equal to the third gap (the gap between the roller 220 and the first groove surface 111) during the design, when the roller 220 abuts the first groove surface 111, a certain gap will still be maintained between the drawer body 200 and the cover body 300, avoiding direct contact between the drawer body 200 and the cover body 300 during the opening process, thereby preventing noise, friction or damage caused by contact, protecting the surface of the cover body 300 from being scratched or worn, extending the service life of the cover body 300, and improving the user experience, making the drawer opening process smoother, quieter and more reliable.

[0067] According to one embodiment of the present application, referring to Figure 1 As shown, the cover 300 has a first sealing surface 310 , and the drawer body 200 has a second sealing surface 230 opposite to the first sealing surface 310 . The first sealing surface 310 is parallel to the second sealing surface 230 .

[0068] In this embodiment, the first sealing surface 310 and the second sealing surface 230 are parallel, ensuring that they fully and evenly mate when the drawer is closed, avoiding local gaps or misalignment, thereby ensuring a reliable seal. Furthermore, parallel sealing surfaces reduce unnecessary friction and wear during matement, extending the service life of the sealing surfaces. For example, the upper end surface of the cover 300 is flat, while the lower end surface, i.e., the first sealing surface 310, is inclined. The second sealing surface 230 is designed to match the first sealing surface 310.

[0069] According to one embodiment of the present application, referring to Figure 1 As shown, the range of the preset angle A is greater than 0 and less than or equal to 5 degrees.

[0070] In this embodiment, a smaller angle range (0-5 degrees) helps ensure a smooth transition of the drawer during opening and closing, reducing the phenomenon of jamming or increased resistance caused by excessively large angles.

[0071] In an optional embodiment, the preset angle A between the sliding direction of the drawer body 200 and the sealing surface of the drawer body 200 and the cover body 300 is 2 degrees, that is, the angle between the second sealing surface 230 and the extension direction of the guide rail 210 is 2 degrees, so that the drawer can remain smooth during the sliding process, and it can also ensure that the gap between the drawer body 200 and the cover body 300 is small enough in the closed state.

[0072] According to one embodiment of the present application, referring to Figure 1 As shown, a hand groove 240 is provided at the bottom of the drawer body 200 for the user to pull the drawer body 200.

[0073] It will be appreciated that in this embodiment, a hand grip groove 240 is provided at the bottom of the drawer body 200 for the user to pull the drawer body 200. The hand grip groove 240 provides the user with a clear grip point, allowing the user to pull the drawer more stably and with less effort. Furthermore, by pulling the drawer through the hand grip groove 240, the user can more precisely control the speed and force of opening the drawer, avoiding unexpected situations caused by directly pulling the drawer panel, such as pulling the drawer out too quickly and striking surrounding objects.

[0074] The hand grip groove 240 is located at the bottom of the drawer body 200, which is convenient for user operation, protects the integrity of the drawer surface, and improves the overall aesthetics.

[0075] In a second aspect, the present application provides a refrigeration device comprising a cabinet and a drawer assembly according to any one of the above embodiments.

[0076] In this embodiment, the refrigeration device can be a household appliance such as a refrigerator, freezer, refrigerated display cabinet, wine cabinet, or ice maker. The housing defines a mounting space, and the drawer assembly is retractably mounted within the housing. The drawer assembly provides more flexible and convenient storage space for the refrigeration device. Users can categorize and store different types of food or items in separate drawers as needed, providing convenient access while maintaining a clean and tidy interior.

[0077] In some embodiments, depending on specific needs, the drawer assembly can also integrate various additional functions, such as temperature control, humidity adjustment, sterilization and deodorization, etc. These functions can further improve the performance of the refrigeration equipment and meet users' higher requirements for food preservation and storage.

[0078] It should be noted that when the drawer assembly is installed on the box body, the guide rail seat 100 and the box body can be manufactured and molded simultaneously during the injection molding process, so that they become an integral component. This method simplifies the production process, reduces the assembly links, and improves production efficiency. Since there is no seam between the guide rail seat 100 and the box body, the overall structure is more compact and stable, and the sealing and durability are also better. The guide rail seat 100 and the box body can also be manufactured separately, and then assembled together through a specific connection method (such as screws, snaps, etc.). This method increases the flexibility of production, and different guide rail seats 100 and box bodies can be selected for combination as needed. At the same time, since the guide rail seat 100 can be disassembled and replaced separately, it is convenient for maintenance and repair. The specific installation method can be designed according to the use requirements, and this embodiment does not specifically limit this.

[0079] It can be understood that if the drawer assembly has the beneficial effects of the above embodiment, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiment. Its specific implementation can refer to the above embodiment, and this embodiment will not elaborate on it.

[0080] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be covered by the scope of protection of the present application.
