[0033] In the description of the present utility model, unless otherwise clearly defined, terms such as setting, installing, connecting, assembling, and matching should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model based on the specific content of the technical solution.

[0034] Reference Figures 1 to 5 As shown, the first embodiment of the utility model provides a storage assembly, which is applied to a refrigerator and is mainly used to store food to meet the requirements of freshness preservation. The refrigerator here can be a single-door refrigerator, a double-door refrigerator, or an air-cooled frost-free refrigerator.

[0035] Reference Figure 1 As shown, it can be understood that the storage assembly includes a box 100, which is fixedly installed in the outer shell of the refrigerator. Generally speaking, there is a temperature insulation layer between the outer wall of the box 100 and the inner wall of the shell to prevent the loss of cold and ensure the refrigeration effect in the box 100. The box 100 has an inner cavity 110 opening forward, and the inner cavity 110 can be used as a storage space alone to meet the storage of large food, or divided into multiple storage spaces to achieve classified storage of food. It is easy to understand that the side where the door of the refrigerator is installed is the front side, and the side facing away is the rear side.

[0036] Reference Figure 1 As shown, it can be understood that the storage assembly also includes a drawer 200 and a shelf 300. Specifically, in this embodiment, the shelf 300 can be detachably installed in the box 100, and the inner cavity 110 is divided into multiple layers of storage space arranged in sequence along the up and down direction. For example, the inner walls on the left and right sides of the inner cavity 110 are respectively provided with supporting protrusions, and the two supporting protrusions are symmetrically arranged in the left and right directions, and the shelf is supported by the two supporting protrusions. It is easy to understand that the up and down direction here is the height direction of the refrigerator, and the left and right direction is perpendicular to the height direction of the refrigerator. In this embodiment, the drawer 200 is installed in the storage space located at the bottom of the box 100. Of course, the drawer 200 can also be installed in other storage spaces.

[0037] Reference Figure 1 and Figure 2 As shown, it can be understood that the drawer 200 is slidably installed in the box 100 along the front-back direction, and the shelf 300 is located above the drawer 200. Specifically, the upper end of the drawer 200 has an opening, and the user can place the food in the drawer 200 through the opening, or take out the food from the drawer 200 through the opening. The left and right sides of the drawer 200 are respectively provided with guide grooves 220, and the two guide grooves 220 are symmetrically arranged. The guiding direction of the guide grooves 220 is arranged along the front-back direction. Correspondingly, the inner walls on the left and right sides of the inner cavity 110 are respectively installed with pulleys that cooperate with the guide grooves 220, and the pulleys are accommodated in the guide grooves 220 and can roll relative to the groove walls of the guide grooves 220. Therefore, the drawer 200 can be slidable in the front-back direction, and the user only needs to pull out the drawer 200 to take and put the food, which is convenient to operate. Of course, the drawer 200 can also be installed on the box 100 through a special guide rail, and the installation method of the drawer 200 is not specifically limited here.

[0038] In other embodiments, the drawer 200 may be directly supported on the bottom wall of the box 100 , and the user may freely pull out or push in the drawer 200 .

[0039] Reference Figure 1 and Figure 2As shown, it can be understood that in this embodiment, two drawers 200 located below the shelf 300 are slidably installed in the box 100, and the two drawers 200 are arranged side by side in the left and right directions. The two drawers 200 can be opened and closed separately for easy use. The following takes one of the drawers 200 as an example to explain in detail the sealing structure between the drawer 200 and the shelf 300, and the other drawer 200 can refer to the sealing structure.

[0040] Reference Figure 2 and Figure 3 As shown, it can be understood that the storage assembly also includes a sealing cover 400, and the sealing cover 400 is located between the shelf 300 and the drawer 200. Specifically, the sealing cover 400 is movably installed on the shelf 300 in the up-down direction. For example, the sealing cover 400 is slidably installed on the shelf 300 in the up-down direction through a structure in which a slide rail and a slider cooperate, or the sealing cover 400 is installed on the shelf 300 through a telescopic rod and can be telescopically moved in the up-down direction, or the sealing cover 400 is installed on the shelf 300 in a manner in which a hanging buckle 320 and a hanging hole 430 cooperate and can be moved in the up-down direction. The connection method between the sealing cover 400 and the shelf 300 is not limited here, and it is only necessary to enable the sealing cover 400 to move in the up-down direction relative to the shelf 300, and the sealing cover 400 will not be separated from the shelf 300.

[0041] It can be understood that the area of ​​the sealing cover 400 is larger than the opening area of ​​the drawer 200 and can cover the opening. That is, thanks to the fact that the sealing cover 400 can move in the up and down directions, when the drawer 200 is pushed into the inner cavity 110, the sealing cover 400 can fall onto the drawer 200 and cover the opening, thereby ensuring good sealing between the sealing cover 400 and the edge of the opening of the drawer 200.

[0042] Reference Figure 2 and Figure 3 As shown, it can be understood that the storage assembly also includes a functional module 500, which can be a lighting module, a deodorizing module, etc. The number of the functional modules 500 can be multiple and include different types. The functional module 500 is installed in the middle position of the lower end surface of the shelf 300. Correspondingly, a through hole 440 is provided in the middle of the sealing cover 400, and the through hole 440 penetrates the upper and lower end surfaces of the sealing cover 400 in the up and down direction. The functional module 500 can be penetrated in the through hole 440, or the functional module 500 is located directly above the through hole 440, and the functional module 500 is located directly above the space surrounded by the inner peripheral wall of the through hole 440, so that the functional module 500 can be exposed to the drawer 200 through the through hole 440. Therefore, the drawer 200 can be provided with lighting or deodorizing treatment, thereby enriching the function of the drawer 200 to meet the additional functional requirements of the drawer 200, and the sealing cover 400 will not interfere with the functional module 500, and the structure is reasonably arranged.

[0043] Reference Figure 3 and Figure 4 As shown, it can be understood that, since the sealing cover 400 is provided with a through hole 440, in order to ensure the sealing of the drawer 200, the sealing of the matching part of the sealing cover 400 and the shelf 300 must also be ensured. To this end, the lower end surface of the shelf 300 is provided with a convex rib 310, and correspondingly, the upper end surface of the sealing cover 400 is provided with a groove 410, that is, the convex rib 310 and the groove 410 are respectively located on the opposite sides of the shelf 300 and the sealing cover 400 in the up and down direction, and the convex rib 310 is inserted into the groove 410. Specifically, the convex rib 310 is arranged to protrude downward, and the convex rib 310 is annular and arranged around the outer periphery of the through hole 440, such as a circular ring or a rectangular shape. Correspondingly, the opening of the groove 410 is upward and arranged around the outer periphery of the through hole 440, and the shape of the groove 410 matches the shape of the convex rib 310, that is, the groove 410 is also annular. The convex rib 310 is correspondingly inserted into the groove 410. Generally speaking, in order to ensure the mobility of the sealing cover 400 in the up-down direction, there is a gap between the outer wall of the convex rib 310 and the inner wall of the groove 410, so that the convex rib 310 can move in the groove 410 in the up-down direction, that is, the convex rib 310 and the groove 410 are not tightly inserted. At the same time, within the range of movement of the sealing cover 400 relative to the shelf 300 in the up-down direction, the convex rib 310 always remains inserted in the groove 410.

[0044] Thus, for the matching part of the shelf 300 and the sealing cover 400, if the gas leaks, that is, the gas flows from the space surrounded by the rib 310 to the outer peripheral space of the rib 310 or flows in the opposite direction, the gas needs to flow through the groove 410 and bypass the rib 310 to flow from one side of the inner periphery and the outer periphery of the rib 310 to the other side. That is to say, a curved channel is formed at the matching part of the rib 310 and the groove 410, like a maze, which on the one hand prolongs the path that the gas needs to flow through when leaking, and on the other hand, the gas needs to bypass the rib 310, and the flow resistance of the gas when leaking increases, so that the difficulty of gas leakage is increased, the kinetic energy of the gas is consumed, and the gas leakage is reduced, which also improves the sealing performance of the matching part of the shelf 300 and the sealing cover 400. Combined with the annular rib 310 and the groove 410, the sealing performance of the four sides of the matching part of the shelf 300 and the sealing cover 400 is good, so that the matching part of the shelf 300 and the sealing cover 400 always has good sealing performance. The inner side of the convex rib 310 is the side of the convex rib 310 close to the center of the opening, and the opposite side is the outer side of the convex rib 310 .

[0045] Therefore, the sealing cover 400 covers the opening of the drawer 200, and the sealing cover 400 cooperates with the shelf 300 through the ribs 310 and the grooves 410, so that the drawer 200 has a good sealing effect, thereby reducing the humidity fluctuation in the drawer 200, achieving sealing and moisturizing, and effectively improving the preservation effect. In addition, there is no need to seal between the shelf 300 and the drawer 200 by setting a silicone seal arranged along the circumference of the opening, which can reduce the amount of silicone seals used, thereby reducing the manufacturing cost.

[0046] At the same time, it is easy to understand that when the user pulls out the drawer 200, the sealing cover 400 always remains connected to the shelf 300, and the drawer 200 is pulled out and the opening is exposed, and there is no need to open the sealing cover 400, which is convenient for the user. When the drawer 200 is pushed in, the sealing cover 400 automatically covers the opening to achieve sealing and ensure the fresh-keeping effect.

[0047] It is understandable that in other embodiments, the positions of the convex rib 310 and the groove 410 on the shelf 300 and the sealing cover 400 can be interchanged, that is, the shelf 300 can be provided with a groove 410 opening downward, and the sealing cover 400 can be provided with a convex rib 310 protruding upward. Similarly, the groove 410 and the convex rib 310 are arranged around the periphery of the through hole 440, and the convex rib 310 is plugged into the groove 410. In this way, the matching part of the shelf 300 and the sealing cover 400 can always have good sealing performance. The sealing principle can refer to the above description and will not be repeated here.

[0048] Reference Figure 2 and Figure 4 As shown, it can be understood that the number of the ribs 310 and the grooves 410 is set to be multiple, and the number of the ribs 310 is equal to the number of the grooves 410. Specifically, the multiple ribs 310 are arranged around in sequence, that is, of the two adjacent ribs 310, the ribs 310 located on the outside are arranged around the outer periphery of the ribs 310 located on the inside, and the minimum inner diameters of the multiple ribs 310 increase from the inside to the outside. Correspondingly, the positions of the multiple grooves 410 correspond to the positions of the multiple ribs 310 one by one, and the multiple ribs 310 are respectively plugged into the multiple grooves 410. In this way, when the gas leaks, it needs to enter the multiple grooves 410 in sequence, and bypass the multiple ribs 310 in sequence. The required flow path is more curved and longer, and the flow resistance is greater, so that the gas leakage can be further reduced, the sealing effect can be improved, and then it is beneficial to improve the fresh-keeping effect of the drawer 200. In this embodiment, the number of the ribs 310 and the grooves 410 is set to two. Of course, the number of the ribs 310 and the grooves 410 can also be three, four or more.

[0049] Reference Figure 4As shown, it can be understood that the minimum groove width of the groove 410 is greater than the maximum thickness of the rib 310 along the width direction of the groove 410, and the width direction of the groove 410 is from the inside to the outside of the rib 310 and the reverse direction. Specifically, along the width direction of the groove 410, the rib 310 has two opposite walls, namely the first wall 311 and the second wall 312, wherein the first wall 311 is located on the left side of the second wall 312, and the maximum thickness of the rib 310 is the maximum distance between the first wall 311 and the second wall 312 in the width direction of the groove 410. The groove 410 has two oppositely arranged walls, namely the third wall 411 and the fourth wall 412, wherein the third wall 411 is located on the left side of the fourth wall 412, and the minimum groove width of the groove 410 is the minimum distance between the third wall 411 and the fourth wall 412. In this way, after the convex rib 310 is inserted into the groove 410, there is a gap between the convex rib 310 and the groove 410, ensuring that the convex rib 310 can move in the groove 410 in the up-down direction, that is, ensuring the mobility of the sealing cover 400. Generally speaking, there is a gap between the first wall surface 311 and the third wall surface 411, and there is also a gap between the second wall surface 312 and the fourth wall surface 412, that is, there is a gap between both sides of the convex rib 310 and the wall surface of the groove 410, which can make the convex rib 310 move more smoothly in the groove 410, that is, the sealing cover 400 moves more smoothly with less resistance, ensuring that the sealing cover 400 can fall normally and cover the opening to achieve sealing and moisturizing.

[0050] Reference Figure 4As shown, it can be understood that since there are gaps between both sides of the rib 310 and the wall of the groove 410, after the drawer 200 is pushed in, the sealing cover 400 covers the opening. At this time, the distance between the lower end wall of the rib 310 and the bottom of the groove 410 is large, and the width of the space there is greater than the width of the above-mentioned gap, that is, the volume of the space between the lower end wall of the rib 310 and the bottom of the groove 410 is greater than the volume of the above-mentioned gap. If gas leaks, the gas needs to pass through the gap between the first wall 311 and the third wall 411, the space between the bottom of the groove 410 and the wall surface of the convex rib 310 facing the bottom of the groove, and the gap between the second wall 312 and the fourth wall 412 in sequence, or pass through the above positions in reverse. In this way, when the gas enters the space between the bottom of the groove 410 and the wall surface of the convex rib 310 facing the bottom of the groove from the gap between the first wall 311 and the third wall 411, or enters the space between the bottom of the groove 410 and the wall surface of the convex rib 310 facing the bottom of the groove from the gap between the second wall 312 and the fourth wall 412, the gas pressure drops and the gas expands, forming a vortex in the space between the bottom of the groove 410 and the wall surface of the convex rib 310 facing the bottom of the groove, further increasing the flow resistance when the gas leaks, and converting the kinetic energy of the gas into heat energy, thereby effectively reducing gas leakage, improving the sealing, and ensuring the moisturizing effect of the drawer 200.

[0051] Reference Figure 2 and Figure 4 As shown, it can be understood that the upper end of the drawer 200 has a first end face 210 facing the sealing cover 400, that is, the first end face 210 is arranged upward, and the first end face 210 is arranged around the outer periphery of the opening. Correspondingly, the lower end of the sealing cover 400 has a second end face 420 facing the drawer 200, that is, the second end face 420 is arranged downward. When the drawer 200 is fully pushed in, the sealing cover 400 falls, and the first end face 210 and the second end face 420 at least partially conflict. In this implementation, the first end face 210 and the second end face 420 completely conflict to ensure the sealing between the drawer 200 and the sealing cover 400, and improve the moisturizing effect of the drawer 200. Of course, it can also be that the first end face 210 located on the left and right sides and the rear side of the opening conflicts with the second end face 420, and the front end of the drawer 200 is directly sealed with the shelf 300 through the sealing strip. Of course, considering the processing error, there is a certain gap between some positions of the first end surface 210 and the second end surface 420, which does not affect the sealing of the drawer 200.

[0052] Reference Figure 4As shown, it can be understood that, along the vertical direction, the maximum insertion depth of the rib 310 inserted into the groove 410 is H, which satisfies 0.1mm≤H≤50mm. The maximum insertion depth of the rib 310 inserted into the groove 410 is the maximum distance between the end surface at the notch of the groove 410 and the wall surface of the rib 310 facing the groove bottom of the groove 410 in the vertical direction. When H≥0.1mm, it can ensure that the rib 310 is always inserted into the groove 410 to achieve sealing; when H≤50mm, considering the limited space between the shelf 300 and the drawer 200, under the premise of ensuring the sealing effect, the insertion depth of the rib 310 is avoided to be too large, and the protruding height of the rib 310 does not need to be too large, thereby reducing the space occupied by the rib 310 and the groove 410, improving the space utilization rate of the drawer 200, while reducing the material consumption and reducing the cost. Therefore, setting 0.1 mm ≤ H ≤ 50 mm, for example, H = 1 mm, H = 5 mm, H = 10 mm or H = 20 mm, etc., is beneficial to reducing costs while ensuring the sealing effect.

[0053] Reference Figure 4 As shown, it can be understood that, along the vertical direction, the minimum distance between the rib 310 and the bottom wall of the groove 410 is L, which satisfies 0.5mm≤L≤30mm. The bottom wall of the groove 410 is the wall surface of the groove bottom, and the minimum distance between the rib 310 and the bottom wall of the groove 410 is the minimum distance between the wall surface of the groove bottom of the groove 410 facing downward from the rib 310 and the bottom wall of the groove 410 in the vertical direction. When L≥0.5mm, there can be enough distance between the rib 310 and the bottom wall of the groove 410 to ensure that the sealing cover 400 can move up and down normally; when L≤30mm, the depth of the groove 410 does not need to be too deep under the premise of satisfying the mobility of the sealing cover 400, which reduces the space occupied by the groove 410 and reduces the processing difficulty. Therefore, by setting 0.5 mm ≤ L ≤ 30 mm, for example, L = 1 mm, L = 5 mm, L = 10 mm or L = 20 mm, etc., the processing difficulty can be reduced while ensuring the mobility of the sealing cover 400 .

[0054] Reference Figure 2 and Figure 5As shown, it can be understood that in this embodiment, the sealing cover 400 is installed on the shelf 300 by means of the matching of the hanging buckle 320 and the hanging hole 430. Specifically, the lower end surface of the shelf 300 is provided with a hanging buckle 320, and the hanging buckle 320 can be located on the side of the rib 310 (or the groove 410) close to the through hole 440 or on the side away from the through hole 440. Correspondingly, the sealing cover 400 is provided with a hanging hole 430. The hanging buckle 320 includes a plurality of elastic arms 321, which extend downward and a limiting portion 322 is provided at the lower end of the elastic arm 321. The plurality of elastic arms 321 are arranged at equal intervals along the circumference of the hanging hole 430, so that the elastic arms 321 can be deformed along the radial direction of the hanging hole 430, that is, the plurality of elastic arms 321 can shrink toward the middle or expand outward along the radial direction of the hanging hole 430. The limiting portion 322 is provided to protrude outward along the radial direction of the hanging hole 430. The hanging buckle 320 is passed through the hanging hole 430, and after the limiting portion 322 passes through the hanging hole 430, the limiting portion 322 is located at the end of the hanging hole 430 away from the shelf 300, and a part of the structure of the limiting portion 322 or the whole is offset from the hanging hole 430 in the radial direction of the hanging hole 430, that is, a part of the structure of the limiting portion 322 or the whole is located radially outside the surface of the inner circumferential wall of the hanging hole 430, so that the limiting portion 322 can limit the sealing cover 400 from being separated from the shelf 300, thereby realizing the connection between the sealing cover 400 and the shelf 300, and the sealing cover 400 can move freely in the up and down directions on the upper side of the limiting portion 322. In this way, when the drawer 200 is pushed in, the drawer 200 drives the sealing cover 400 to deflect upward, and the second end surface 420 of the sealing cover 400 keeps contacting the first end surface 210 of the drawer 200 to achieve sealing; when the user pulls out the drawer 200, the opening of the drawer 200 is directly exposed, which is convenient for the user to take and put food, and the sealing cover 400 deflects downward under the action of gravity. Due to the action of the limiting portion 322, the sealing cover 400 can be prevented from separating from the shelf 300. After the user pushes the drawer 200 in again, the sealing cover 400 deflects upward again and covers the opening to achieve sealing. The user does not need to operate the sealing cover 400 during the whole process, which is convenient to use.

[0055] Reference Figure 5 As shown, it can be understood that when the sealing cover 400 is installed on the shelf 300, the sealing cover 400 is pressed into the hanging buckle 320, and the inner peripheral wall of the hanging hole 430 contacts the limiting portion 322 and drives the multiple elastic arms 321 of the hanging buckle 320 to shrink toward the middle. After the limiting portion 322 passes through the hanging hole 430, the multiple elastic arms 321 automatically reset, and the sealing cover 400 can be hung on the shelf 300, which is simple to operate and easy to assemble. In addition, the hanging buckle 320 and the shelf 300 are an integrated structure, which is easy to manufacture. The way in which the hanging buckle 320 cooperates with the hanging hole 430 is simple in structure and low in manufacturing cost.

[0056] It is understandable that in other embodiments, the hook 320 may also be a straight rod structure and provided with a limiting portion 322 radially protruding along the hanging hole 430, and the hook 320 may rotate around a rotation axis arranged in the up-down direction. Correspondingly, the sealing cover 400 is provided with a notch located on one side of the hanging hole 430, and the notch is connected to the hanging hole 430. When installing the sealing cover 400, the limiting portion 322 is aligned with the notch and the hook 320 is inserted into the hanging hole 430. After the limiting portion 322 passes through the hanging hole 430, the hook 320 is rotated so that the limiting portion 322 and the notch are staggered in the circumferential direction of the hanging hole 430. Similarly, the sealing cover 400 can be moved in the up-down direction and remain connected to the shelf 300.

[0057] Reference Figure 4 and Figure 5 As shown, it can be understood that in this embodiment, the number of the hooks 320 and the number of the hanging holes 430 are both four, and the four hooks 320 are arranged at equal intervals along the circumference of the opening, and the positions of the hanging holes 430 correspond to the positions of the hooks 320 one by one, and the four hooks 320 are correspondingly penetrated in the four hanging holes 430, so that the installation stability of the sealing cover 400 can be improved. Of course, the number of the hooks 320 and the hanging holes 430 can also be five, six or more.
