[0042] Please see the appendix Figure 1-10 This utility model provides an embodiment of a drawer 30 humidity control device for a household refrigerator, comprising a shelf assembly 10 and two drawer 30 humidity control units arranged side-by-side in a horizontal direction. The drawer 30 humidity control units are disposed below the shelf assembly 10 and are movably arranged in a longitudinal direction. Each drawer 30 humidity control unit includes a humidity control component 20 and a drawer 30, with the humidity control component 20 positioned above the drawer 30. First, it should be noted that in this application, "longitudinal" refers to the direction of pull-out movement of the drawer 30, where the front end refers to the direction of pull-out and the rear end refers to the direction of push-back. "Horizontal" refers to the width direction of the drawer 30. Please refer to the accompanying drawings for details. Specifically:

[0043] The humidity regulating assembly 20 includes a humidity regulating cover 210 and an adjuster 220. The humidity regulating cover 210 covers the drawer 30, and an adjustment space 230 is formed between the humidity regulating cover 210 and the shelf assembly 10. The rear end of the humidity regulating cover 210 is hinged to the rear end of the shelf assembly 10, and the front end of the humidity regulating cover 210 is rotatably arranged around the rear end. The adjuster 220 is connected to the lower part of the front end of the shelf assembly 10 and is movably arranged laterally. The adjuster 220 has a downwardly protruding inclined block 2 extending laterally. 21. The inclined side of the inclined block 221 is provided with an inclined flange 222. The front end of the humidity control cover 210 is provided with an upwardly protruding hook 211 and a recessed anti-interference groove 212. The hook 211 is hung on the flange 222 of the inclined block 221. The anti-interference groove 212 is located near the lower end of the flange 222. When the regulator 220 moves laterally to the point where the hook 211 is hung on the higher end of the flange 222, the front end of the humidity control cover 210 rotates upward to form an open state with the drawer 30.

[0044] Specifically, the humidity control device for drawer 30 of a household refrigerator in this application includes a shelf assembly 10 and two drawer 30 humidity control units arranged side by side in the horizontal direction. The shelf assembly 10 serves as a shelf for storing food and dishes inside the refrigerator and also facilitates the connection of the drawer 30 humidity control units. Two drawer 30 humidity control units are arranged side by side and are connected to the bottom of the shelf assembly 10. Furthermore, each drawer 30 humidity control unit includes a humidity control component 20 and a drawer 30. The drawer 30 is used to store food and dishes. The humidity control component 20 covers the drawer 30 to form a sealed space to ensure humidity. The humidity inside the drawer 30 can be changed by adjusting the size of the opening between the humidity control component 20 and the drawer 30.

[0045] The humidity regulating assembly 20 includes a humidity regulating cover 210 and an adjuster 220. The humidity regulating cover 210 covers the drawer 30, and its rear end is hinged to the rear end of the shelf assembly 10 to allow rotation. This allows the front end of the humidity regulating cover 210 to rotate around its rear end. Therefore, to ensure sufficient rotation range, an adjustment space 230 is formed between the humidity regulating cover 210 and the shelf assembly 10. This adjustment space 230 is the range within which the humidity regulating cover 210 can be rotated and adjusted. Because this space is relatively small in height... Therefore, even if it is a circular rotational motion of the front end around the hinge axis of the rear end, it can be approximated as a lifting motion when the stroke is short. The opening size is changed by lifting, thereby changing the humidity. The regulator 220 is easy for the user to operate to drive the adjustment and lifting of the entire humidity-regulating cover 210. It is connected to the lower front end of the shelf assembly 10. The adjustment is achieved by the cooperation between the inclined block 221 below it and the hook 211 at the front end of the humidity-regulating cover 210. The inclined flange 222 protruding on the inclined block 221 facilitates the hook 211 to be attached.

[0046] In such detail, the regulator 220 can only move laterally. Considering the inclined design of the ramp 221, initially the hook 211 is attached to the lower end of the flange 222 of the ramp 221. When the regulator 220 moves laterally, the contact point between the hook 211 and the flange 222 of the ramp 221 will rise along the inclined surface. As it gradually moves towards the higher end of the flange 222 of the ramp 221, it will exert an upward pulling force on the hook 211. Under the action of this upward pulling force, the front end of the entire humidity control cover 210 will move upward. Combined with the rear hinge, the front end will rotate upward around the rear end. During this process, the front end of the humidity control cover 210 and the drawer 3... The openings between the 0 and 0 gradually open, thus creating different humidity environments. When the regulator 220 moves laterally until the hook 211 is attached to the high end of the flange 222, the front end of the humidity-regulating cover 210 rotates upward to form an open state with the drawer 30. This open state is the state with the largest opening, i.e., the state with the lowest humidity. Conversely, the humidity is the highest when closed. It is worth mentioning that as the front end of the humidity-regulating cover 210 rises higher, it gets closer to the inclined block 221. At this time, as the inclined block 221 moves laterally, it moves towards the anti-interference groove 212 to avoid interference between the inclined block 221 and the humidity-regulating cover 210, so as to ensure the normal operation of the entire lifting process.

[0047] In a preferred embodiment of the present invention, the shelf assembly 10 includes a front trim strip 110, a glass shelf 120, and a rear trim strip 130. The rear trim strip 130 is hinged to the rear end of the humidity regulating cover 210. The adjuster 220 is connected below the front trim strip 110. The rear end of the front trim strip 110 is recessed to form a first groove, and the front end of the rear trim strip 130 is recessed to form a second groove. The two ends of the glass shelf 120 are respectively connected to the first groove and the second groove to be engaged between the front trim strip 110 and the rear trim strip 130.

[0048] It should be noted that the front trim strip 110 and the rear trim strip 130 are used for the installation and fixation of the glass shelf 120, which is used for placing food, dishes, etc. The front trim strip 110 and the rear trim strip 130 have a first groove and a second groove respectively recessed on the opposite side (the rear end of the front trim strip 110 and the front end of the rear trim strip 130). These two grooves are used for the glass shelf 120 to be locked in, thereby ensuring the stability of the installation connection. It can be understood that the rear trim strip 130 can also be used for the hinge of the humidity control cover 210, so as to serve as the hinge point of the humidity control cover 210.

[0049] In a preferred embodiment of this utility model, the front trim strip 110 protrudes downward to form two buckle groups, and each drawer 30 humidity control unit is provided with one buckle group; wherein, each buckle group includes four buckles 111 distributed in a matrix, and the front and rear sides of the adjuster 220 are respectively provided with guide strips 223 protruding outward, and the adjuster 220 is connected to the buckles 111 by means of the guide strips 223 to be movably connected between the four buckles 111 in the lateral direction.

[0050] It should be noted that the buckle assembly is used for the adjustment device 220 to be installed. Four buckles 111 arranged in a matrix form a buckle space for the adjustment device 220 to be installed. For the installation connection, guide strips 223 are formed on both sides of the adjustment device 220. The installation is completed by the guide strips 223 resting on the buckles 111. The adjustment device 220 can be slidably connected to the four buckles 111 in the lateral direction.

[0051] In a preferred embodiment of the present invention, the front trim 110 has two through-hole slots 112, and each of the drawer 30 humidity control units is provided with one through-hole slot 112; wherein, the top of the adjuster 220 is provided with an upwardly protruding slider 224, the slider 224 is engaged in the through-hole slot 112 and the top extends out of the front trim 110.

[0052] It is worth noting that the through-hole groove 112 is used to cooperate with the slider 224 of the regulator 220. Firstly, it can limit the sliding range of the regulator 220 and play a guiding role. Secondly, the slider 224 can extend out of the front trim strip 110 so that the user can easily access it and operate it. The user can adjust the raising and lowering of the humidity control cover 210 by moving the slider 224.

[0053] In a preferred embodiment of this utility model, the front trim strip 110 is provided with two sets of limiting strips 113 protruding downwards, and each drawer 30 humidity control unit is provided with a set of limiting strips 113; wherein, the top of the adjuster 220 is provided with a locking block 225 protruding upwards, and each set of limiting strips 113 is recessed to form three slots 114 arranged laterally, the slots 114 are used for the locking block 225 to engage, and each slot 114 is inclined at both ends in the lateral direction.

[0054] It is worth noting that the limiting strip 113 is used to cooperate with the locking block 225 of the regulator 220. Three locking slots 114 are recessed on the limiting strip 113, and each locking slot 114 represents a gear (i.e., the opening size of the humidity control cover 210). When the regulator 220 moves laterally until the locking block 225 is engaged in a locking slot 114, it is fixed in this opening position, and at the same time, it can prevent the humidity control cover 210 from closing by itself under the action of gravity. Furthermore, the interval between two adjacent locking slots 114 in each set of limiting strips 113 is equal to half the length of the through hole groove 112. It should be noted that this makes the three positions of the slider 224 when it is engaged in the locking slot 114 in the through hole groove 112 respectively at both ends and the middle position. At both ends, it is in the open state and the closed state, while the middle position is in the half-open state. The three gears of open-half-closed correspond to low-medium-high humidity respectively.

[0055] Furthermore, the front trim strip 110 protrudes downward to form two front hanging lugs, and each of the drawer 30 humidity control units is provided with one set of the front hanging lugs; wherein, each front hanging lug includes two front hanging lugs 115 arranged laterally opposite each other, and the front ends of the humidity control cover 210 protrude upward to form two front hanging lugs 213 arranged laterally opposite each other, the side of the front hanging lug 115 is recessed to form a limiting groove, and the side of the front hanging lug 213 is protruded to form a protruding post, and the protruding post is connected to the limiting groove.

[0056] It should be noted that the front hanging lug 115 of the front trim strip 110 can cooperate with the front hanging lug 213 of the humidity regulating cover 210. The protrusion of the front hanging lug 213 is set in the limiting groove of the front hanging lug 115 to limit the lifting range of the humidity regulating cover 210.

[0057] Furthermore, the rear trim strip 130 protrudes downward to form two rear hanging lugs, and each of the drawer 30 humidity control units is provided with one set of the rear hanging lugs; wherein, each of the rear hanging lugs includes two rear hanging lugs 131 arranged laterally opposite each other, and the rear ends of the humidity control cover 210 protrude upward to form two rear hanging lugs 214 arranged laterally opposite each other, and the rear hanging lugs 131 and the rear hanging lugs 214 are hinged to each other.

[0058] It should be understood that the rear hanging lug 131 allows the hinge point to be located at a certain distance below the rear trim strip 130, so as to form sufficient adjustment space 230. The rear hanging lug 214 protruding on the humidity control cover plate 210 is used to cooperate with the rear hanging lug 131 for hinge connection, so that the hinge shaft can pass through.

[0059] Furthermore, the two ends of the rear trim strip 130 are also provided with downward protruding support legs 132, which are used to be snapped into the refrigerator.

[0060] It should be noted that the support leg 132 can be engaged with the front lug 115 of the front trim 110 to be snapped into the protruding part of the refrigerator liner, thereby fixing the front trim 110, the rear trim 130 and the glass shelf 120 snapped between them horizontally.

[0061] Furthermore, the two ends of the through-hole groove 112 are provided with inclined surfaces.

[0062] Understandably, this creates an inclined space between the inclined surfaces at both ends of the through-hole groove 112 and the slider 224. This inclined space makes it easier for personnel to operate and adjust the slider 224, making the operation more convenient.

[0063] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
