[0038] ​​​​​In order to make the purpose, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in conjunction with the drawings.

[0039] In the following description of the present application, the same numbers in different drawings represent the same or similar elements unless otherwise noted. The implementations described in the following exemplary embodiments are not meant to be an all-inclusive description of all implementations consistent with the present application. Rather, they are merely examples that are illustrative of some of the many possible devices and methods consistent with the present application as detailed in the appended claims.

[0040] In the description of the present application, it should be understood that the terms "first", "second" and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance. The above terms can be understood by those of ordinary skill in the art in the context of the present application. In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The association relationship of the associated objects is described, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0042] Generally, a drawer is usually provided in the refrigeration compartment of a refrigerator to store food, achieving the purpose of preservation.

[0043] In the related art, a refrigerator includes an evaporator (cold source) and a return air inlet. The evaporator is located at the back or bottom of the refrigerator, used to generate cold air, and distribute the cold air evenly to each corner of the interior of the refrigerator through an air duct. The return air inlet is usually provided on one side close to the door of the refrigerator, used to re-introduce the cold air into the air duct to form an air circulation field.

[0044] The front side of the drawer is usually at the return air inlet, and the moisture generated by the transpiration of the food in the drawer is easily taken away by the air field, causing the food to lose water, which is not conducive to the storage of the food.

[0045] To this end, the embodiments of the present application provide a refrigerator to improve the sealing performance of the drawer, thereby improving the preservation function of the refrigerator.

[0046] Specifically, please refer to Figures 1 to 5 , Figure 1A schematic diagram of the structure of the refrigerator drawers, lids, and partitions provided in an embodiment of this application; Figure 2 for Figure 1 Exploded view of the structure in the image; Figure 3 for Figure 1 A schematic diagram of the structure from a top-down perspective; Figure 4 for Figure 3 A cross-sectional view along the AA direction; Figure 5 This is a magnified view of part B in the figure.

[0047] The refrigerator of this embodiment includes a cabinet, a drawer 1, and a cover 2. A refrigerator compartment is provided inside the cabinet. The drawer 1 has an opening 11 and is pull-out into the refrigerator compartment. A receiving part 12 is connected to the inner side wall of the drawer 1. The cover 2 is connected to the cabinet and closes at the opening 11 when the drawer 1 is stored in the refrigerator compartment. The receiving part 12 protrudes from the inner side wall of the drawer 1 and abuts against the cover 2 when the cover 2 is closed at the opening 11 to seal the gap between the cover 2 and the inner side wall of the drawer 1.

[0048] Furthermore, the refrigerator also includes a partition 3 for separating the refrigerator compartment. The partition 3 is fixedly connected to the refrigerator body, and the cover 2 is movably connected to the bottom surface of the partition 3 so as to move toward the opening 11 and close the opening 11.

[0049] In this embodiment, the cabinet adopts a rectangular hollow structure, which serves as the outer shell of the refrigerator. It is understood that the cabinet can also adopt other hollow shell structures. The cabinet is made of high-strength materials, such as stainless steel, which has good heat insulation performance and durability. Heat insulation material is installed inside the cabinet to improve the refrigerator's heat preservation performance. Multiple mutually separated refrigeration compartments, such as freezer and refrigerator compartments, can be set inside the cabinet to meet different refrigeration needs for freezing and refrigeration according to different types of food. These multiple refrigeration compartments can be arranged vertically or horizontally. The front of the cabinet has a door, which is connected to the cabinet shell by a hinge, allowing the refrigerator door to rotate around the axis of the hinge, thus opening and closing the refrigerator. It should be noted that the vertical and horizontal orientations described in this embodiment refer to... Figure 2 The indicated directions are as follows: when a person is facing directly in front of the refrigerator, the side closer to the person is the front side, and the side farther away from the person is the back side.

[0050] The partition 3 is made of sturdy materials, such as rigid plastic or stainless steel, and can be fixed inside the cabinet by welding or bolting. It effectively divides the space and can withstand a certain weight. The partition 3 separates the refrigeration compartment inside the cabinet into a refrigerator compartment, which has a suitable size for storing various foods.

[0051] The drawer 1 can be made of plastic or metal material, thereby having good strength and corrosion resistance. The drawer 1 is shaped to match the refrigerating chamber to maximize the space in the refrigerating chamber, and can be square. The drawer 1 has an upward opening 11, and a pulley or a guide rail is installed on the outer side or the bottom of the drawer 1, so that the drawer 1 can be smoothly pushed and pulled in the refrigerating chamber, thereby facilitating the user to take and place articles.

[0052] The cover plate 2 is movably connected to the bottom surface of the partition plate 3, for example, the cover plate 2 is movably connected to the bottom surface of the partition plate 3 by a hinge, a sliding rail, a snap buckle or the like, and has a certain stroke in the vertical direction, so that the cover plate 2 can move towards the drawer 1 under its own gravity and cover the opening 11 of the drawer 1. In this way, the bottom surface of the cover plate 2 better matches the end surface of the opening 11, thereby sealing the opening 11 of the drawer 1.

[0053] To further improve the sealing performance of the drawer 1, as shown in Figure 2 and Figure 5 , the inner side wall of the drawer 1 is connected with a receiving portion 12, and the receiving portion 12 protrudes from the inner side wall of the drawer 1. The receiving portion 12 can be a separate component that is detachably connected to the inner side wall of the drawer 1, or can be a part of the inner side wall of the drawer 1. The shape of the receiving portion 12 can be strip-shaped, block-shaped, etc. In the present embodiment, the receiving portion 12 is strip-shaped and is arranged along the edge of the inner side wall of the drawer 1, and the length thereof is adapted to the side edge of the drawer 1.

[0054] When the cover plate 2 covers the opening 11, the receiving portion 12 protrudes from the inner side wall of the drawer 1 and abuts against the cover plate 2, thereby blocking the gap between the cover plate 2 and the inner side wall of the drawer 1. In this way, the water vapor generated by the evaporation of food carried by the cold air can be effectively prevented, thereby maintaining a low-temperature environment in the drawer 1 and improving the preservation effect of the refrigerator.

[0055] In some embodiments, please refer to Figure 5 and Figure 6 , Figure 6 is a structural schematic diagram of the drawer 1 in the present embodiment; the receiving portion 12 of the present embodiment has a first surface 1221 that is flush with the end surface of the opening 11, and the first surface 1221 is used to match the bottom surface of the cover plate 2. The first surface 1221 can be the top surface of the receiving portion 12, which is flush with the end surface of the opening 11, thereby forming a flat surface together with the end surface of the opening 11. When the drawer 1 is in a closed state, the first surface 1221 closely matches the bottom surface of the cover plate 2, thereby effectively blocking the gap between the cover plate 2 and the inner side wall of the drawer 1. The first surface 1221 is usually designed to be flat to ensure that the bottom surface of the cover plate 2 can be fully contacted, thereby achieving good sealing effect.

[0056] Further, the bottom surface of the cover plate 2 has a protruding second surface 21 that is used to match the first surface 1221.

[0057] The second surface 21 is designed to better fit the first surface 1221 of the receiving portion 12. The protruding shape of the second surface 21 can be designed according to actual needs, and common ones are round protrusions, strip-shaped protrusions, etc. The height and shape of the protrusion should match the first surface 1221 of the receiving portion 12 to ensure that when the drawer 1 is in the closed state, the second surface 21 can be tightly pressed on the first surface 1221, achieving good sealing effect.

[0058] During the process of pushing the drawer 1, when the drawer 1 gradually approaches the closed state, the second surface 21 of the cover plate 2 will gradually face the first surface 1221 of the receiving portion 12. Since the second surface 21 is protruding, it will first contact the first surface 1221, and during the process of continuing to push the drawer 1, gradually apply pressure on the first surface 1221, thereby more tightly fitting on the second surface 21. In this way, the gap between the cover plate 2 and the inner side wall of the drawer 1 is sealed, effectively preventing the leakage of cold air.

[0059] In one embodiment, please refer to Figure 7 , Figure 7 The structure diagram of the receiving portion 12 in this embodiment; the receiving portion 12 includes a first body 121 and a second body 122, one end of the first body 121 is connected with the side wall of the drawer 1, the other end of the first body 121 extends towards the cover plate 2 to form the second body 122, and the first surface 1221 is the top surface of the second body 122. Further, the first body 121 has a third surface 1211 facing the cover plate 2, which is used to fit with the side surface of the cover plate 2. The first surface 1221 and the third surface 1211 together form a sealing structure, effectively sealing the gap between the cover plate 2 and the inner side wall of the drawer 1.

[0060] The first body 121 can be a connecting plate, one end of which is hung on the top edge of the inner side wall of the drawer 1 and can be fixed by screws. The hanging mode makes the installation of the first body 121 more firm and not easy to fall off. The other end of the connecting plate has a folded edge with a certain width to form a horizontally arranged bearing surface and define the folded edge as the second body 122 of the receiving portion 12. The design of the folded edge increases the contact area of the receiving portion 12 and the cover plate 2, improving the sealing effect.

[0061] The first surface 1221 is the bearing surface of the folded edge, which is used to fit with the bottom surface of the cover plate 2. The first surface 1221 should be kept flat to ensure that the bottom surface of the cover plate 2 can be fully contacted to form a good seal.

[0062] The third surface 1211 is the surface of the connecting plate facing the cover plate 2, which is used to fit with the side surface of the cover plate 2.

[0063] When the user pushes the drawer 1 into the refrigeration chamber, the drawer 1 is in a closed state, and the cover plate 2 is naturally covered on the opening 11 under the action of gravity. At this time, the first face 1221 of the receiving portion 12 is attached to the bottom face of the cover plate 2, and the third face 1211 is attached to the side face of the cover plate 2, forming a sealing structure and effectively plugging the gap between the cover plate 2 and the inner side wall of the drawer 1.

[0064] Further, the angle formed by the third face 1211 and the first face 1221 of the receiving portion 12 is obtuse. In this way, when the cover plate 2 is covered on the opening 11, the side face of the cover plate 2 can be better attached to the third face 1211, increasing the contact area and thus improving the sealing performance. At the same time, the obtuse angle design also enables the receiving portion 12 to provide a certain buffer when in contact with the cover plate 2, avoiding damage to the cover plate 2 and the receiving portion 12 caused by hard contact.

[0065] In another embodiment, please refer to Figure 8 , Figure 8 is a structural schematic diagram of the drawer 1 in the embodiment; the receiving portion 12 includes a platform 123, the platform 123 protrudes from the inner side wall of the drawer 1, and the first face 1221 is the top face of the platform 123.

[0066] In the embodiment, the platform 123 is part of the drawer 1 and is integrally formed with the drawer 1. In this way, the connection between the receiving portion 12 and the drawer 1 is more secure and less likely to be damaged, and the complexity of assembly is also reduced.

[0067] The protruding part of the platform 123 forms a platform, and the top face of the platform is the first face 1221. When the cover plate 2 is covered on the opening 11, the top face of the platform 123 is tightly attached to the bottom face of the cover plate 2, thereby effectively plugging the gap between the cover plate 2 and the inner side wall of the drawer 1 and preventing the leakage of cold air.

[0068] In some embodiments, as shown in Figure 6 , the drawer 1 includes a main body 13 and a panel 14 connected to the front side of the main body 13, and the receiving portion 12 is connected to the panel 14 and protrudes from the inner wall of the panel 14.

[0069] In the embodiment, the main body 13 can be connected by a bottom plate and three side plates, that is, the drawer 1 is formed by the bottom plate, the panel 14, and the three side plates. The panel 14 is located at the front side of the drawer 1.

[0070] The return air inlet of the air field in the refrigerator is usually close to the front side of the opening 11 of the drawer 1. If the sealing performance of the drawer 1 is not good, the cold air may leak out from the front side of the opening 11, affecting the refrigeration effect of the refrigerator. The receiving portion 12 of the embodiment is connected to the panel 14 and protrudes from the inner wall of the panel 14, thereby abutting against the part of the cover plate 2 facing the panel 14, preventing the leakage of cold air from the front side of the opening 11 and improving the sealing performance of the drawer 1.

[0071] In some embodiments, please refer to Figure 9 and Figure 10 , Figure 9 the structure diagram of the cover plate 2 provided in the embodiment; Figure 10 the structure diagram of the partition plate 3 provided in the embodiment.

[0072] The bottom surface of the partition plate 3 has a fastener 31, and the cover plate 2 has a first through hole 22 through which the fastener 31 can pass. The fastener 31 extends towards the opening 11. The cover plate 2 can move along the extension direction of the fastener 31.

[0073] Further, a plurality of first through holes 22 are provided on the cover plate 2.

[0074] In the embodiment, the bottom surface of the partition plate 3 has a fastener 31, and the fastener 31 extends towards the opening 11. The fastener 31 is usually made of high-strength plastic or metal material and has a certain length and toughness. The installation position of the fastener 31 will affect the stability and reliability of the cover plate 2 during movement. The number and distribution of the fastener 31 can be adjusted according to the size and weight of the cover plate 2. In the embodiment, in general, in order to ensure the balance and stability of the cover plate 2, the fasteners 31 are uniformly distributed on the bottom surface of the partition plate 3.

[0075] The cover plate 2 has a first through hole 22 through which the fastener 31 can pass, and a plurality of first through holes 22 are provided on the cover plate 2. The number and position of the first through holes 22 correspond to the fasteners 31 on the bottom surface of the partition plate 3, ensuring that each fastener 31 can pass through the first through hole 22 on the cover plate 2. The size and shape of the first through hole 22 should be slightly larger than the diameter of the fastener 31, so that the fastener 31 can pass through, while not causing excessive shaking of the cover plate 2 during movement.

[0076] The free end of the fastener 31 has a hook portion 311 for hooking the bottom surface of the cover plate 2. The hook portion 311 can tightly hook the bottom surface of the cover plate 2 when the cover plate 2 moves to a certain position, preventing the cover plate 2 from accidentally falling off. The shape of the hook portion 311 can be a boss shape.

[0077] The cover plate 2 can move along the extension direction of the fastener 31 under the action of its own gravity. When the drawer 1 is in an open state, the cover plate 2 is hung on the fastener 31 under the action of gravity. When the drawer 1 is pushed back into the refrigeration chamber, the opening 11 is gradually closed, and the cover plate 2 moves downward along the fastener 31 under the action of gravity, and finally is pressed on the end surface of the opening 11, realizing sealing. This movement mode is simple and reliable, without the need for additional power devices, saving cost and improving the reliability of the refrigerator.

[0078] The design of the plurality of buckles 31 corresponding to the plurality of first through holes 22 makes the cover plate 2 more stable during movement. Compared with the traditional single connection mode, this design can better withstand the weight of the cover plate 2 and prevent the cover plate 2 from tilting or shaking during movement. At the same time, the cover plate 2 can be tightly pressed against the end face of the opening 11 under the action of its own gravity, which can effectively improve the sealing performance of the refrigerator, thereby preventing cold air leakage, maintaining the temperature stability in the drawer 1, and prolonging the preservation time of food.

[0079] When the drawer 1 is pushed in or pulled out, the panel 14 of the drawer 1 will come into contact with the side edge of the partition plate 3. Therefore, the partition plate 3 of the present embodiment is also provided with a buffer strip 33. Specifically, as shown in Figure 5 the buffer strip 33 is arranged on the side edge of the partition plate 3 facing the panel 14. The arrangement of the buffer strip 33 at this position can effectively reduce the impact force between the drawer 1 and the partition plate 3, making the movement of the drawer 1 more stable.

[0080] The buffer strip 33 is usually made of materials with elasticity, such as rubber, silicone, etc. These materials have good elasticity and wear resistance, can quickly recover to their original state after bearing a certain pressure, and can withstand long-term use without damage.

[0081] The shape of the buffer strip 33 can be designed according to the shape of the partition plate 3 and the drawer 1, and is generally long strip-shaped. The size of the buffer strip 33 should be adjusted according to the size and weight of the drawer 1 to ensure that it can effectively play a buffering role. Generally, the length is adapted to the length of the side edge of the partition plate 3.

[0082] The buffer strip 33 can be installed on the side edge of the partition plate 3 by pasting, inlaying, etc. The pasting method is to coat the back of the buffer strip 33 with glue and then directly paste it on the side edge of the partition plate 3. The inlaying method is to open a groove on the side edge of the partition plate 3, inlay the buffer strip 33 in the groove, and then fix the buffer strip 33 in the groove by glue or other fixing methods.

[0083] In some embodiments, the bottom surface of the partition plate 3 is provided with a lighting assembly, and the middle part of the cover plate 2 is configured with a second through hole 23 for avoiding the lighting assembly.

[0084] The lighting assembly can adopt different types of lamps such as LED lamps, fluorescent lamps, etc. LED lamps have the advantages of energy saving, long service life, high brightness, etc., and are currently more commonly used lighting lamps.

[0085] The lighting assembly is installed on the bottom surface of the partition plate 3 and can be fixed on the bottom surface of the partition plate 3 by screws, buckles or the like. The middle part of the cover plate 2 is configured with a second through hole 23 for avoiding the lighting assembly. The position of the second through hole 23 should correspond to the position of the lighting assembly to ensure that the light of the lighting assembly can pass through the second through hole 23 and irradiate into the interior of the drawer 1. The shape of the second through hole 23 can be designed according to the shape and size of the lighting assembly, and is generally circular, square or the like. The size of the second through hole 23 is larger than that of the lighting assembly to facilitate the installation and maintenance of the lighting assembly.

[0086] In some embodiments, please refer to Figure 9 、 Figure 10 and Figure 11 wherein, Figure 11 is Figure 4 a local enlarged view at C in FIG. 4, the top surface of the cover plate 2 of the embodiment has an annular groove 24 surrounding the second through hole 23; the bottom surface of the partition plate 3 also has a stop edge 32 matched with the annular groove 24, and the stop edge 32 is used to be inserted into the annular groove 24 to seal the second through hole 23.

[0087] In the embodiment, the shape of the annular groove 24 can be circular, square or other shapes, and the depth and width thereof should be designed according to actual needs to ensure that it can be tightly matched with the stop edge 32. The annular groove 24 can be provided with multiple turns to improve the sealing effect. The multiple turns of the annular groove 24 can increase the contact area between the stop edge 32 and the annular groove 24, thereby better preventing the leakage of cold air.

[0088] The shape of the stop edge 32 should match the annular groove 24, and the height thereof should be slightly greater than the depth of the annular groove 24 to ensure that it can be inserted into the annular groove 24 and form a good seal. The stop edge 32 can be formed by being integrally protruded from the bottom surface of the partition plate 3, or can be made of rubber, silicone or other elastic materials to ensure that it can be tightly fitted when inserted into the annular groove 24 and form a good seal.

[0089] When the cover plate 2 covers the opening 11 of the drawer 1, the stop edge 32 on the bottom surface of the partition plate 3 is inserted into the annular groove 24 on the top surface of the cover plate 2 to form a sealing structure, effectively preventing the leakage of cold air from the second through hole 23. This sealing structure can improve the sealing performance of the drawer 1, reduce the leakage of cold air, thereby improving the preservation effect of the refrigerator and prolonging the storage time of food.

[0090] The same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components; in the description of the present application, it is understood that if the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right" and the like are based on the orientations or positional relationships shown in the drawings, they are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationships in the drawings are only used for exemplary illustration and cannot be understood as a limitation on the present application, for those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.
