[0040] See also Figures 1 to 13 The embodiment of the present application provides a fresh-keeping drawer, including a drawer 100 and a cover assembly 200. The open end periphery of the drawer 100 is provided with a first folding assembly 300, and the side of the cover assembly 200 facing the drawer 100 is provided with a second folding assembly 400 corresponding to the first folding assembly 300. When the cover assembly 200 covers the drawer 100, the second folding assembly 400 presses against the first folding assembly 300 under the self-weight of the cover assembly 200.

[0041] In this embodiment, the fresh-keeping drawer 10 is provided with a first folding assembly 300 on the open periphery of the drawer 100, and a second folding assembly 400 corresponding to the first folding assembly 300 is provided on the periphery of the cover assembly 200. In this way, when the cover assembly 200 is covered on the open end of the drawer 100, the connecting surface of the second folding assembly 400 is attached to the connecting surface of the first folding assembly 300 to form a sealing area at the connection between the cover assembly 200 and the drawer 100; and, under the action of its own gravity, the second folding assembly 400 has a pressure against the first folding assembly 300 to further enhance the sealing effect of the sealing area and improve the fresh-keeping effect of the fresh-keeping drawer 10. In addition, the fresh-keeping drawer 10 uses the own gravity of the cover assembly 200 to compact / tighten the fitting surface between the second folding assembly 400 and the first folding assembly 300, which on the one hand ensures the sealing of the inner chamber of the drawer 100; on the other hand, compared with the traditional double-layer nested drawer structure, the fresh-keeping drawer 10 in this embodiment has a simple structure, occupies a small space, and can provide a large fresh-keeping space.

[0042] Specifically, the fresh-keeping drawer 10 is configured as a combined component including at least a drawer 100 and a cover assembly 200. Figure 1 As shown, the drawer 100 may be a frame-type structure with an open top, the first folding component 300 may be a long plate-like structure, which is arranged at the open periphery of the frame-type structure; the cover plate component 200 may be a plate-like rectangular structure with a certain thickness, and the second folding component 400 may be a long plate-like structure, which is arranged at the periphery of the plate-like rectangular structure.

[0043] In one example, when the fresh-keeping drawer 10 is applied to a fresh-keeping device such as a refrigerator, the cover assembly 200 can be clamped between the inner wall of the refrigerator and the middle partition opposite to the inner wall of the refrigerator by means of the claws protruding outward on the rear edge thereof, so that the cover assembly 200 does not move along the width direction X as the drawer 100 is pulled out. The cover assembly 200 is at a certain distance from the bottom of the refrigerator, and the distance at least satisfies the height distance of the drawer 100, so that the drawer 100 can extend into the fresh-keeping cavity enclosed by the inner wall of the refrigerator, the rear wall of the refrigerator, the middle partition, the bottom wall of the refrigerator, and the cover assembly 200. When the drawer 100 is fully extended into the fresh-keeping chamber, the cover assembly 200 completely covers the open opening of the drawer 100, and the second folding assembly 400 at the periphery of the cover assembly 200 is completely fitted and compacted with the first folding assembly 300 at the periphery of the drawer 100 under the action of the gravity of the cover assembly 200, so as to realize fresh-keeping and moisture-locking for the crops such as fruits and vegetables placed in the drawer 100. When the crops need to be taken out, the drawer 100 can be pulled out. The whole fresh-keeping drawer 10 is easy to operate and has excellent fresh-keeping effect.

[0044] In one example, slides are provided on the inner wall and the side wall of the middle partition of the refrigerator, guide rails and rollers are provided on the two outer walls of the drawer 100, and the drawer 100 is slidably connected in the slides through the rollers, so that the user can pull out the drawer 100 conveniently; part of the guide rail is accommodated in the slide, which has a guiding function.

[0045] In a possible embodiment, the cover assembly 200 includes a cover body 210 and a reinforcement 220, the reinforcement 220 is arranged at the side edge of the cover body 210 and extends along the width direction X of the cover assembly 200, and the reinforcement 220 is located on the inner side of the second folding assembly 400; the first folding assembly 300 includes a first folding edge 310 corresponding to the reinforcement 220 and a second folding edge 320 corresponding to the second folding edge assembly 400, the first folding edge 310 extends along the width direction X of the drawer 100 and is folded outward along the length direction Y of the drawer 100, and the second folding edge 320 is arranged on a side of the first folding edge 310 away from the drawer 100, and extends out of the first folding edge 310 in the height direction Z of the drawer 100. In this way, a double-layer sealing area can be formed at least at the contact surface between the reinforcement 220 and the first folding edge 310 and at the contact surface between the second folding edge assembly 400 and the first folding edge 310, thereby improving the sealing effect of the fresh-keeping drawer 10.

[0046] like Figures 5 to 11 As shown, the cover body 210 may be a square plate with a certain thickness, the reinforcement 220 may be a long strip structure with a certain thickness, and two reinforcements 220 may be provided, and the two reinforcements 220 are respectively provided on the left and right side edges of the cover body 210 in the depth direction, and the two reinforcements 220 are opposite and located on the inner side of the second folding edge assembly 400. The first folding edge 310 may be a long narrow plate, which is vertically connected to the outer edge of the open end of the drawer 100; the second folding edge 320 may be a long narrow plate, which is vertically connected to the outer edge of the first folding edge 310, and the plate surface width of the first folding edge 310 is greater than the plate surface width of the second folding edge 320. When the cover plate assembly 200 is covered on the drawer 100, the reinforcement member 220 of the cover plate assembly 200 abuts against the upper surface of the first folding edge 310, and at this time, a planar first sealing area can be formed at the connection between the reinforcement member 220 and the first folding edge 310; at the same time, the second folding edge assembly 400 of the cover plate assembly 200 abuts against the upper surface of the second folding edge 320 and the side wall surface facing the first folding edge 310, and forms a second sealing area of ​​an inverted L-shaped surface there. In this way, by pressing at least three contact surfaces of the first folding edge assembly 300 and the second folding edge assembly 400 together, the sealing of the left and right side edges of the cover plate assembly 200 and the drawer 100 in the depth direction is achieved, and the sealing effect is ensured.

[0047] In a possible embodiment, the cover assembly 200 further includes a connecting fold 230, which is arranged around the periphery of the cover body 210, and the reinforcement 220 is arranged on the inner side of the connecting fold 230. The second fold assembly 400 includes a third fold 410 extending along the width direction X of the cover assembly 200, and the third fold 410 is arranged on the outer side of the connecting fold 230 corresponding to the reinforcement 220, and is folded outward along the length direction Y of the drawer 100. In this way, on the one hand, the connecting fold 230 can provide a connection position of a certain height for the third fold 410, and on the other hand, the additional connecting fold 230 can increase its contact area with the first fold assembly 300, thereby enhancing the sealing effect.

[0048] like Figures 5 to 11 As shown, the cover assembly 200 is configured as a composite component including at least a cover body 210, a reinforcement 220 and a connecting fold 230. The connecting fold 230 may be a rectangular frame structure. One end of the connecting fold 230 may be connected to the periphery of the cover body 210 by welding or the like, so as to enclose the cover body 210 to form a half-box structure. To improve the stability of the connection, the reinforcement 220 may be connected to the cover body 210 by welding or the like. The third fold 410 may be a long narrow plate, which is vertically connected to the outer wall of the connecting fold 230. The connection between the third fold 410 and the connecting fold 230 and the free end of the connecting fold 230 is at a certain distance, and the second fold 320 can be inserted into the cover assembly 200 when it is covered on the drawer 100, so that the upper surface of the second fold 320 abuts against the upper surface of the third fold 410, and the inner side wall of the second fold 320 abuts against the outer side wall of the connecting fold 230 at this distance. In this way, by increasing the contact area between the second fold 320 and the third fold 410 and part of the connecting fold 230, the sealing performance between the second fold assembly 400 and the first fold assembly 300 is enhanced, and the sealing effect is improved.

[0049] In a possible implementation, the reinforcement member 220 includes a reinforcement plate 221 and a plurality of reinforcement ribs 222 disposed between the reinforcement plate 221 and the cover body 210, and the reinforcement plate 221 is received in the connecting fold 230. Such an arrangement can not only reduce the overall weight of the reinforcement member 220, making it easier for the user to draw the drawer 100, but also increase the contact area between the connecting fold 230 and the inner side wall of the drawer 100, thereby enhancing the sealing effect.

[0050] like Figures 9 to 11As shown, in order to reduce the weight of the reinforcement 220, the reinforcement 220 is configured as a composite component including at least a reinforcement plate 221 and a plurality of reinforcement ribs 222, and the upper surface of the reinforcement plate 221 is lower than the upper surface of the connecting fold 230, so that a T-angle area is formed between the reinforcement plate 221 and the connecting fold 230. When the cover assembly 200 is covered on the drawer 100, the upper surface of the reinforcement plate 221 is pressed against the first fold 310, and the outer wall surface of the protruding portion of the connecting fold 230 is fitted with the inner wall of the second fold 320 to form a T-shaped sealing area to enhance the sealing effect.

[0051] In a possible embodiment, the first folding edge assembly 300 further includes a fourth folding edge 330 disposed at the rear edge, the fourth folding edge 330 extending along the length direction Y of the drawer 100 and folding outward along the width direction X of the drawer 100, and the second folding edge assembly 400 further includes a fifth folding edge 420 corresponding to the fourth folding edge 330, the fifth folding edge 420 extending along the length direction Y of the cover plate assembly 200 and folding outward along the width direction X of the cover plate. In this configuration, the fifth folding edge 420 abuts against the fourth folding edge 330 to enhance the sealing performance of the connection between the cover plate assembly 200 and the drawer 100 at the rear edge.

[0052] like Figure 2 , Figures 5 to 11 As shown, in order to enhance the sealing performance of the connection between the rear edge of the cover plate assembly 200 and the drawer 100, a fourth folded edge 330 vertically connected to the drawer 100 is provided at the rear edge of the drawer 100, and the fourth folded edge 330 can be a long narrow plate; at the same time, a fifth folded edge 420 vertically connected to the cover plate assembly 200 is provided at the rear edge of the cover plate assembly 200, and the fifth folded edge 420 can be a long narrow plate. The fourth folded edge 330 and the fifth folded edge 420 both have a certain plate width to ensure that the fifth folded edge 420 and the fourth folded edge 330 are tightly attached to each other and have a good sealing effect.

[0053] It should be explained that the rear edge refers to the rear end of the drawer 100 in the depth direction, that is, the end away from the user. The rear edge used below has the same meaning as this explanation, and will not be repeated in detail.

[0054] In one example, for the convenience of processing, the fourth folded edge 330 is connected to the first folded edge 310 to form an integrated folded edge. A circular arc chamfer structure can be provided at the corner area between the fourth folded edge 330 and the first folded edge 310 to achieve a smooth connection.

[0055] In a possible implementation, the front edge of the drawer 100 is further provided with a drawer 110, and the drawer 110 extends out of the first folding assembly 300 in the height direction Z of the drawer 100, and the second folding assembly 400 further includes a sixth folding edge 430 corresponding to the drawer 110, and the sixth folding edge 430 is provided on a side of the connecting folding edge 230 away from the cover body 210, and is folded outward along the height direction Z of the cover assembly 200. In this configuration, the sixth folding edge 430 is in contact with the drawer 110 to enhance the sealing performance of the connection between the cover assembly 200 and the front edge of the drawer 100.

[0056] like Figure 1 and Figure 2 , 5 to Fig.11 As shown, in order to enhance the sealing performance of the front end, the front edge of the drawer 110 is extended out of the first folding component 300, and the drawer 110 can be a plate-like structure with a certain thickness, which constitutes a part of the drawer 100; at the same time, a sixth folding edge 430 is arranged at the front edge of the cover plate component 200 in the opposite direction to the second folding component 400, and the sixth folding edge 430 can be a plate-like structure. The sixth folding edge 430 has a certain plate width to ensure that the sixth folding edge 430 has a good sealing effect after being tightly attached to the part of the drawer 110.

[0057] It should be explained that the front edge refers to the front end of the drawer 100 in the depth direction, that is, the end close to the user. The rear edge used below has the same meaning as this, and will not be repeated in detail.

[0058] See also Figure 7 In a possible embodiment, a mounting groove is provided on the side of the cover body 210 away from the reinforcement member 220, and the cover assembly 200 also includes an oxygen and humidity control component 240 and a fixing component 250, the oxygen and humidity control component 240 is installed in the mounting groove, and the fixing component 250 is embedded in the mounting groove and pressed against the oxygen and humidity control component 240.
