Description

Technical Field

[0001] This application relates to the field of refrigerator fruit and vegetable preservation technology, and in particular to a drawer assembly and a refrigerator. Background Technology

[0002] To preserve the freshness of fruits and vegetables, a drawer in the refrigerator needs to maintain a high humidity environment. Currently, a moisture-retaining cover is used to cover the fruit and vegetable drawer, creating a sealed space to keep it moist. When the drawer is closed, the moisture-retaining cover rests directly on the top surface of the drawer; when the drawer is pulled out, the cover falls down, and the lugs on both sides of the cover engage with the supporting structure on both sides of the drawer (such as the drawer slides), keeping the cover in place.

[0003] However, the current moisturizing cover and drawer have poor preservation effect: when the drawer is pulled out repeatedly, the moisturizing cover is often not sealed tightly, resulting in gaps between the two, which causes moisture inside the drawer to leak out and affect the preservation effect. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a drawer assembly to solve the problem of poor airtightness and easy moisture loss in the humidification space inside existing refrigerators, thereby improving the preservation effect of the refrigerator.

[0005] This application also proposes a refrigerator.

[0006] According to a first aspect embodiment of the present application, a drawer assembly includes: A drawer with an opening at the top; A cover plate covers the upper opening of the drawer to form a moisture-retaining cavity with the drawer; the cover plate includes a cover plate body and a first wind deflector strip, the first wind deflector strip is disposed at the rear end of the cover plate body, the cover plate body and the drawer have a fitting gap, and the first wind deflector strip is disposed at the rear end position corresponding to the fitting gap.

[0007] According to one embodiment of this application, when the cover plate covers a preset position of the drawer, there is a reserved gap between the first wind deflector and the rear end of the drawer.

[0008] According to one embodiment of this application, a second wind baffle is provided at both sides of the cover plate body in the width direction, and the second wind baffle corresponds to both sides in the width direction of the mating gap; The second wind deflector is connected to the first wind deflector to form a U-shaped wind deflector structure.

[0009] According to one embodiment of this application, the drawer and the cover plate are in a non-contact engagement along the height direction of the drawer.

[0010] According to one embodiment of this application, the mating gap is greater than 0 mm and less than or equal to 2 mm.

[0011] According to one embodiment of this application, the cover plate body, the first windbreak strip, and the second windbreak strip are an integral component; or The cover plate body, the first wind deflector strip, and the second wind deflector strip are separate components. The cover plate body is provided with one of a slot or a protrusion, and the first wind deflector strip and the second wind deflector strip are provided with the other of a slot or a protrusion. The cover plate body, the first wind deflector strip, and the second wind deflector strip are connected by a snap-fit ​​connection based on the slot and the protrusion.

[0012] According to one embodiment of this application, the drawer has a flange at its rear end; The first wind deflector includes a vertical section extending along the height of the drawer and a horizontal section extending along the horizontal direction; the first wind deflector and the flange cooperate to extend the path length of the reserved gap.

[0013] According to one embodiment of this application, a first magnetic chuck is provided at the rear end of the cover body, and a second magnetic chuck is provided at the rear end of the drawer. The first magnetic chuck and the second magnetic chuck cooperate to constrain the relative position of the cover and the drawer.

[0014] According to one embodiment of this application, the first wind deflector extends vertically downward along the height direction of the drawer; or The first wind deflector extends at an angle toward the drawer along the height of the drawer.

[0015] A refrigerator according to a second aspect of this application, the refrigerator comprising: Box; The aforementioned drawer assembly is installed in the housing.

[0016] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects: In the drawer assembly of this application, a first air baffle is provided at the rear end of the cover. This first air baffle can cover the gap between the cover and the drawer, reducing moisture leakage from inside the drawer. Furthermore, the first air baffle also provides good moisture retention even when the cover and drawer are not precisely aligned (the drawer is not properly pushed back to the preset position): the first air baffle effectively covers the return gap caused by the drawer not being pushed back completely. In addition, the first air baffle also assists in the cover's return to its original position: when the drawer is pulled out, the drawer may cause the cover to shift slightly; when the drawer is pushed back normally, the drawer contacts the first air baffle, causing the cover to fall back to the preset position, further improving the drawer assembly's preservation effect on vegetables and fruits.

[0017] Furthermore, the reserved gap effectively avoids the risk of mechanical interference. The existence of the reserved gap provides room for deformation at the rear of the drawer. Even if the rear of the drawer deforms to some extent, it will not mechanically interfere with the first wind deflector, ensuring that the drawer always maintains smooth pull-out performance and maintains the normal function of the components.

[0018] Furthermore, extending the path length of the reserved gap can enhance the sealing performance of the humidity-retaining cavity. The cooperation between the rear flange of the drawer and the first air deflector (vertical section + horizontal section) allows the reserved gap to form a "zigzag" or "stepped" path. This forces moisture to bypass the area where the vertical and horizontal sections meet the flange when diffusing from inside the drawer, rather than overflowing directly through a straight path. The extended path length increases the resistance to moisture diffusion, reduces moisture leakage, further optimizes the sealing environment of the humidity-retaining cavity, and is more conducive to maintaining the humidity conditions required for fruit and vegetable storage, thus improving the preservation effect.

Furthermore, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification, as well as the features of different embodiments or examples. "A plurality of" should be understood as two or more.

[0038] A drawer assembly according to an embodiment of the first aspect of this application, such as Figures 1 to 3As shown, the drawer assembly includes: a drawer 1 with an upper opening 11; and a cover 2 covering the upper opening 11 of the drawer 1 to form a moisture-retaining cavity with the drawer 1. The cover 2 includes a cover body 21 and a first air deflector 22. The first air deflector 22 is located at the rear end of the cover body 21, and there is a mating gap 31 between the cover body 21 and the drawer 1. The first air deflector 22 is positioned corresponding to the rear end of the mating gap 31. The first air deflector 22 blocks the mating gap 31, restricting gas (including air and moisture) from entering or exiting the moisture-retaining cavity through the mating gap 31 or through the return gap 32 caused by the drawer 1 not being pushed back into place.

[0039] It should be noted that the return gap 32 is the gap between the drawer 1 and the cover plate 2 when the drawer 1 is not pushed back normally. There is also a fitting gap 31 between the drawer 1 and the cover plate 2. The return gap 32 and the fitting gap 31 are not two completely incompatible concepts. The return gap 32 can be the fitting gap 31 in another state (i.e., the state when the drawer 1 is not pushed back normally).

[0040] The aforementioned "front end of drawer 1 or cover 2" refers to the end closest to the refrigerator door, while the rear end is the end furthest from the refrigerator door. The mating surfaces of drawer 1 and cover 2 can be beveled to ensure that cover 2 does not obstruct drawer 1 from being pulled out or returned to its original position.

[0041] To address the sealing requirements of the humidifying cavity, after the cover plate 2 covers the upper opening 11 of the drawer 1 to form the humidifying cavity, the mating gap 31 between the cover plate body 21 and the drawer 1 is one of the paths for moisture to escape. The first wind deflector 22, located at the rear end of the cover plate body 21 and corresponding to the rear end of the mating gap 31, can directly provide some shielding to the rear area of ​​the mating gap 31, reducing the diffusion of moisture from inside the drawer 1 outwards through this gap. This provides a basic guarantee for the sealing of the humidifying cavity and helps maintain a suitable humidity environment for storing vegetables and fruits inside the drawer 1. It should be understood that the "sealing requirement" of the humidifying cavity refers to minimizing the outflow of moisture from the humidifying cavity, rather than strictly isolating the inside and outside to achieve a completely sealed effect.

[0042] Secondly, considering the actual operation scenario after the drawer 1 is pulled out, the user may not accurately align the drawer 1 when it is pushed back due to operating habits or force control issues (not pushed back to the preset position normally). At this time, an additional return gap 32 will be generated between the cover plate 2 and the drawer 1. The setting of the first wind deflector 22 can not only cover the normal fit gap 31, but also effectively cover the return gap 32. Even if the drawer 1 is not pushed back in place, the first wind deflector 22 can still cover at least part of the return gap 32 area, avoiding the failure of moisturizing due to improper operation, improving the moisturizing stability of the component in non-ideal operating scenarios, and reducing the impact of user operation errors on the preservation effect.

[0043] When drawer 1 is pulled out, friction or vibration can cause the cover plate 2 to shift to a certain extent. If the cover plate 2 cannot return to its original position after displacement, it will further widen the gap 31, affecting the sealing performance. However, when drawer 1 is pushed back normally, after drawer 1 contacts the first air baffle 22, the first air baffle 22 can apply force to the cover plate body 21, causing the cover plate 2 to fall back to the preset position, correcting the displacement deviation of the cover plate 2, ensuring that the cover plate 2 and drawer 1 always maintain a precise fit, further maintaining the sealing performance of the moisture-retaining cavity, and ultimately improving the preservation effect of vegetables and fruits and extending the storage period through a stable humidity environment.

[0044] According to one embodiment of this application, such as Figure 8 As shown, when the cover plate 2 covers the drawer 1 at the preset position, there is a reserved gap 33 between the first wind deflector 22 and the rear end of the drawer 1.

[0045] During initial assembly and regular use, when the cover plate 2 covers the drawer 1 in the preset position, the reserved gap 33 between the first air baffle 22 and the rear end of the drawer 1 will not affect the core function of the first air baffle 22. Previously, the first air baffle 22 already served to cover the mating gap 31 and assist the cover plate 2 in returning to its position. After the size of the reserved gap 33 was designed and adapted, it will not cause the first air baffle 22 to fall out of the covering range of the rear end of the mating gap 31 (it can still effectively reduce moisture leakage from the mating gap 31), nor will it hinder the normal pull-out operation of the drawer 1. When the drawer 1 moves within the preset stroke, the first air baffle 22 and the rear end of the drawer 1 always remain in a non-contact state, avoiding wear caused by friction between the two during regular use and extending the service life of the components.

[0046] The reserved gap 33 can effectively avoid the risk of mechanical interference: During long-term use, drawer 1 is affected by factors such as material aging, changes in environmental temperature and humidity (such as the expansion of wooden drawer 1 due to moisture absorption in humid environments, or the deformation of plastic drawer 1 due to heat), and the accumulation of stress caused by frequent pulling and pulling. The rear end of drawer 1 is prone to slight bulging, warping, or dimensional expansion. The reserved gap 33 provides a space to accommodate the deformation of the rear end of drawer 1. Even if the rear end of drawer 1 deforms to a certain extent, it will not cause mechanical interference with the first wind deflector 22, ensuring that drawer 1 always maintains smooth pulling performance and maintains the normal function of the components.

[0047] The reserved gap 33 also indirectly ensures the long-term sealing of the humidification chamber. If the rear end of drawer 1 deforms and interferes with the first air baffle 22, causing drawer 1 to fail to push back to the preset position normally, a return gap 32 will be generated, leading to moisture leakage from drawer 1, damaging the humidification environment, and affecting the preservation effect of fruits and vegetables. The reserved gap 33 ensures that drawer 1 can push back into place normally by avoiding interference, reducing the generation of return gap 32, and indirectly maintaining the sealing stability of the humidification chamber. This allows the preservation function of the drawer assembly to continue to function effectively during long-term use, improving the reliability of the product and the user experience.

[0048] In some cases, a deformable flexible sealing layer (such as a silicone layer or an elastic sponge layer) can be provided on the side of the first wind deflector 22 facing the rear end of the drawer 1. The thickness of the flexible sealing layer is less than the initial size of the reserved gap 33. In the initial state, the flexible sealing layer does not contact the rear end of the drawer 1 and does not affect the "deformation accommodation" function of the reserved gap 33. When the rear end of the drawer 1 is slightly deformed, the flexible sealing layer can flexibly contact the deformed part, which not only avoids the noise generated by rigid collision, but also fills the tiny gaps in the reserved gap 33 after deformation, reduces the leakage of moisture from the reserved gap 33, and further enhances the moisturizing effect.

[0049] According to one embodiment of this application, such as Figure 7 As shown, a flange 12 is provided at the rear end of drawer 1; the first wind deflector 22 includes a vertical section 221 extending along the height direction of drawer 1 and a horizontal section 222 extending along the horizontal direction; the first wind deflector 22 and the flange 12 cooperate to extend the path length of the reserved gap 33.

[0050] Extending the path length of the reserved gap 33 enhances the sealing performance of the moisture-retaining cavity. The core purpose of the reserved gap 33 is to prevent interference from deformation at the rear end of drawer 1. If the gap itself is a straight path, some moisture inside drawer 1 may still overflow directly along the gap, affecting the moisture retention effect. However, the cooperation between the rear flange 12 of drawer 1 and the first wind deflector 22 (vertical section 221 + horizontal section 222) allows the reserved gap 33 to form a "zigzag" or "stepped" path. This ensures that when moisture diffuses from inside drawer 1 outward, it must bypass the area where the vertical section 221, horizontal section 222, and flange 12 cooperate, rather than overflowing directly through a straight path. Extending the path length increases the resistance to moisture diffusion, reduces moisture overflow, further optimizes the sealing environment of the moisture-retaining cavity, and is more conducive to maintaining the humidity conditions required for fruit and vegetable storage, thus improving the preservation effect. The vertical segment 221 of the first wind deflector 22 extends along the height of drawer 1, and the horizontal segment 222 extends horizontally. The flange 12 corresponds to either the horizontal segment 222 or the vertical segment 221. Figure 7 As shown.

[0051] Without weakening the anti-interference function, the combination of the flange 12 and the segmented first windbreak strip 22 can also improve structural stability. The flange 12 enhances the structural strength of the rear end of the drawer 1, reduces the deformation of the rear end of the drawer 1 during long-term use (such as suppressing warping, bulging, and other deformations), and indirectly extends the effective "deformation accommodation" period of the reserved gap 33. At the same time, the three-dimensional structure formed by the vertical segment 221 and the horizontal segment 222 of the first windbreak strip 22 is easier to form a stable cooperation relationship with the flange 12 compared to a single straight structure, avoiding the first windbreak strip 22 from shifting during the drawer 1's pulling process (such as horizontal displacement or vertical loosening), ensuring that the path length of the reserved gap 33 always remains in the design state, and that the path is not shortened or the seal fails due to component displacement, thus maintaining functional stability during long-term use.

[0052] By extending the path length, the flange 12 and the segmented first windbreak strip 22 improve the sealing effect through path optimization without changing the initial width of the reserved gap 33 (which can still accommodate the deformation of the rear end of the drawer 1). This achieves a balance between "anti-interference requirements" and "strong sealing effect", avoiding the sacrifice of one function for the sake of pursuing one function, and improving the overall performance of the components.

[0053] According to one embodiment of this application, the cover plate 2 further includes reinforcing ribs (not shown in the figure), which are disposed on the rear end face of the cover plate body 21 and the rear end face of the first windbreak strip 22.

[0054] The reinforcing ribs are installed on the rear end face of the cover body 21 and the rear end face of the first wind deflector 22, which can directly improve the structural strength and stability of the rear end of the cover 2 and the first wind deflector 22. The rear end of the cover body 21 is the connecting carrier of the first wind deflector 22, and during the process of the drawer 1 being pushed back, the first wind deflector 22 will come into contact with the rear end of the drawer 1 (such as when assisting the cover 2 to return to its original position). Long-term stress can easily cause deformation of the rear end of the cover body 21 (such as dents or warping), or loosening or breakage of the connection between the first wind deflector 22 and the cover body 21. The presence of the reinforcing ribs can increase the local structural thickness or form a supporting frame, disperse the stress concentration under stress, reduce the risk of deformation of the rear end of the cover body 21, and at the same time strengthen the connection stability between the first wind deflector 22 and the cover body 21, preventing the first wind deflector 22 from falling off or shifting due to stress.

[0055] According to one embodiment of this application, such as Figure 5 As shown, the two sides of the cover plate body 21 in the width direction are provided with second wind baffle strips 23, which correspond to the two sides in the width direction of the mating gap 31; the second wind baffle strips 23 are connected to the first wind baffle strip 22 to form a U-shaped wind baffle structure, which is provided to the two sides in the width direction of the mating gap 31 and the rear end position of the mating gap 31.

[0056] The U-shaped windproof structure significantly expands the coverage area of ​​the mating gap 31, enhancing the sealing performance of the moisture-retaining cavity. The first windproof strip 22 only covers the rear end of the mating gap 31, while some moisture can still leak out from the sides of the mating gap 31. The second windproof strip 23 is located on the side of the cover body 21 and connects with the first windproof strip 22 to form a U-shaped structure. It can cover both sides and the rear end of the mating gap 31 simultaneously, upgrading the originally scattered "rear end coverage" to "three-sided surround coverage". This spatially blocks the main moisture leakage path of the mating gap 31, reduces the total amount of moisture diffusing outward from the drawer 1, and is more conducive to maintaining the stable humidity required for fruit and vegetable storage, thus improving the sustainability of the preservation effect.

[0057] The U-shaped windbreak structure enhances adaptability to non-ideal fit conditions and reduces the impact of operational or usage deviations on the seal. Through integrated three-sided shielding, the U-shaped windbreak structure can block any local deviations in the mating gap 31 at the side or rear end, preventing seal failure due to uncovered gaps. This reduces the impact of user operational errors or minor structural deviations on the moisture retention function and improves the component's fault tolerance.

[0058] The integrity of the U-shaped structure enhances the structural stability of the wind deflector and extends its service life. After the second wind deflector 23 connects with the first wind deflector 22 to form an integrated frame, it is more resistant to lateral forces or vibrations generated when the drawer 1 is pulled out, compared to a single, independently installed wind deflector. The U-shaped structure forms a mutually supporting mechanical structure, reducing the risk of displacement of individual wind deflectors and ensuring that the blocking positions of the side and rear ends always correspond to the mating gap 31. This avoids blocking deviations caused by wind deflector displacement and maintains sealing stability during long-term use.

[0059] According to one embodiment of this application, such as Figure 6 As shown, drawer 1 and cover 2 are in a non-contact fit along the height of drawer 1. During this non-contact fit, cover 2 is also supported by other structures within the refrigerator, such as a limiting groove on the guide rail 4 to support cover 2.

[0060] Non-contact mating directly optimizes the user experience of drawer 1 and extends the lifespan of components. In traditional contact mating, the upper surface of drawer 1 and the lower surface of cover 2 experience continuous friction when pulled out. Over time, this can lead to wear on the contact surfaces (such as surface scratches and material loss), affecting not only the appearance but also potentially creating larger gaps and compromising moisture retention and sealing. Simultaneously, frictional resistance can cause the drawer to become clunky, increasing the effort required for user operation. By setting a smaller gap along the height of drawer 1 to achieve non-contact mating, drawer 1 and cover 2 do not directly contact each other, eliminating frictional resistance during pulling out and making the experience smoother and lighter, reducing the burden on the user. Furthermore, it avoids wear on the contact surfaces, reducing material loss on the upper surface of drawer 1 and the lower surface of cover 2, extending their lifespan and reducing the frequency of component maintenance or replacement.

[0061] The U-shaped windproof structure provides a seal for the non-contact fit, resolving the core issue of moisture leakage caused by the non-contact gap. The non-contact fit increases the gap 31; without effective shielding, moisture in the moisturizing space would overflow along this gap, causing the moisturizing function to fail. The U-shaped windproof structure covers both sides and the rear end of the gap 31, forming a surrounding shield. When moisture diffuses outward from the moisturizing space, it must first overcome the U-shaped windproof structure, significantly blocking the path of moisture overflowing through the gap 31. Only a small amount might slightly leak from uncovered areas (such as the front end), maintaining overall humidity stability within the moisturizing space. This balances the needs for non-contact wear prevention and sealing for moisture retention, avoiding sacrificing the core moisturizing function for the sake of a smooth pull-out experience or durability, and achieving synergistic optimization of multiple performance aspects.

[0062] The non-contact mating structure also improves the long-term stability of the drawer assembly. The absence of friction and wear reduces the risk of deformation between drawer 1 and cover 2, allowing the mating gap 31 to maintain its designed small size over the long term. This prevents the gap from widening due to wear, which would increase the obstruction pressure on the U-shaped windproof structure. Simultaneously, it improves the smoothness of pulling out the drawer, preventing shaking that could cause the mating gap 31 to widen, indirectly ensuring the continuity of the sealing effect.

[0063] According to one embodiment of this application, the fit gap 31 is greater than 0 mm and less than or equal to 2 mm.

[0064] For example, the gap 31 can be 1mm.

[0065] According to one embodiment of this application, the cover plate body 21, the first windbreak strip 22, and the second windbreak strip 23 are integral components. Alternatively, the cover plate body 21, the first windbreak strip 22, and the second windbreak strip 23 are separate components, with one of a slot or a protrusion provided on the cover plate body 21, and the other of a slot or a protrusion provided on the first windbreak strip 22 and the second windbreak strip 23. The cover plate body 21, the first windbreak strip 22, and the second windbreak strip 23 are connected by a snap-fit ​​connection based on the slot and the protrusion; for example, the cover plate body 21 is provided with a slot, and the first windbreak strip 22 and the second windbreak strip 23 are provided with a protrusion, and the snap-fit ​​connection is achieved by inserting the protrusion into the slot.

[0066] The integrated component design directly improves the overall structural stability and sealing reliability of the cover plate 2. The cover plate body 21, the first windbreak strip 22, and the second windbreak strip 23 are formed as a whole through integrated molding (such as injection molding, compression molding, etc.) without any splicing gaps. This avoids the loosening and displacement problems that may occur with separate connections. The integrated structure ensures that the first windbreak strip 22 and the second windbreak strip 23 always maintain a fixed relative position with the cover plate body 21. The U-shaped windbreak structure continuously covers both sides and the rear end of the mating gap 31 without misalignment, stably performing the core function of blocking moisture. At the same time, the integrated structure reduces the assembly process in the production process, eliminating the need for additional connection operations between the windbreak strip and the cover plate body 21, reducing assembly errors (such as windbreak strip installation tilt or positional misalignment), improving production efficiency, and avoiding the risk of sealing failure due to improper assembly.

[0067] During the one-piece molding process, a "gradual thickening part" can be designed in the connection and transition area between the cover body 21 and the first wind deflector 22 and the second wind deflector 23. The gradual thickening part increases in thickness slowly from the cover body 21 towards the wind deflector, rather than suddenly thickening. This can disperse the stress concentration when the drawer 1 is pulled out (such as the impact force on the rear end of the drawer 1 borne by the first wind deflector 22), avoid cracks or deformation in the transition area due to excessive stress, and further extend the service life of the one-piece structure.

[0068] The modular design offers greater flexibility and economical maintenance. When the first baffle 22 or the second baffle 23 wears or breaks due to long-term use (such as friction or collision with drawer 1), it is not necessary to replace the entire cover 2; only the damaged baffle needs to be removed and replaced with a new one, significantly reducing maintenance costs and resource waste. Simultaneously, the modular design allows for the selection of different materials to meet the functional requirements of different components. For example, the cover body 21, which needs to provide structural support, can be made of high-strength plastic or metal. The first baffle 22 and the second baffle 23, which require improved sealing, can be made of elastic rubber or flexible plastic. Material adaptation optimizes the functional performance of each component. Furthermore, the snap-fit ​​connection method using slots and protrusions allows for assembly without complex tools, simplifying operation and quickly positioning the baffle and cover body 21. This ensures that the first baffle 22 and the second baffle 23 accurately form a U-shaped structure after installation, without deviating from the coverage area of ​​the mating gap 31, balancing assembly convenience and connection accuracy.

[0069] In some cases, snap-fit ​​connections can be replaced by adhesive or screw connections.

[0070] According to one embodiment of this application, a first magnetic 211 is provided at the rear end of the cover body 21, and a second magnetic 13 is provided at the rear end of the drawer 1. The first magnetic 211 and the second magnetic 13 cooperate to constrain the relative positions of the cover 2 and the drawer 1.

[0071] The cooperation of the first magnetic component 211 and the second magnetic component 13 effectively improves the accuracy of the relative position of the drawer 1 and the cover plate 2 when the drawer 1 is pushed back, solving the problems of "not in place" or "offset" that easily occur when manually pushing back the drawer. During the process of the user pulling out the drawer 1 and pushing it back, the first magnetic component 211 and the second magnetic component 13 will generate an adsorption force when the drawer 1 is close to the preset position. This adsorption force constrains the relative position of the cover plate 2 and the drawer 1, guiding the drawer 1 to automatically adjust to the precise preset position, ensuring that the relative position of the two is consistent after each push back, and avoiding positional deviations caused by manual operation errors.

[0072] Meanwhile, this structure optimizes the user experience and lowers the barrier to entry. The magnetic attraction does not require the user to apply additional alignment force; simply pushing drawer 1 close to the preset position is enough for the magnetic force to assist in precise repositioning, reducing user fatigue caused by repeatedly adjusting the position of drawer 1. Compared to traditional mechanical positioning structures (such as latches and protrusions), the magnetic attraction eliminates any hard collisions or jamming sensations, making the drawer 1 pushback process smoother and improving the overall user experience.

[0073] The precision of the relative position also indirectly ensures the sealing performance of the humidifying chamber. When drawer 1 and cover 2 are precisely aligned, the U-shaped windproof structure can accurately cover both sides and the rear end of the mating gap 31, preventing misalignment of the windproof structure and the mating gap 31 due to positional deviation. This ensures a stable shielding effect, reduces moisture leakage from the mating gap 31 within the humidifying space, and maintains a suitable humidity environment for fruit and vegetable storage. Simultaneously, the magnetic attraction eliminates mechanical wear (such as wear caused by repeated snap-fitting), resulting in a longer service life for the first magnetic component 211 and the second magnetic component 13. This allows them to maintain positioning accuracy over a long period, ensuring the continuous sealing performance of the components.

[0074] According to one embodiment of this application, the first wind deflector 22 extends vertically downward along the height direction of the drawer 1; or, the first wind deflector 22 extends obliquely towards the drawer 1 along the height direction of the drawer 1.

[0075] When the first baffle strip 22 extends vertically downwards along the height of drawer 1, it can cover the rear end area of ​​the gap 31 with a simple structural form, ensuring the stable realization of the basic shielding function. The vertically extending structure has a simple processing technology (such as no complex angle design is required when it is integrally injection molded), and it is easy to control the dimensional accuracy, which can ensure that the reserved gap 33 between the lower end of the first baffle strip 22 and the rear end of drawer 1 remains uniform.

[0076] When the first baffle strip 22 extends along the height of drawer 1 and tilts towards drawer 1, it can reduce the reserved gap 33 to a certain extent. Furthermore, due to the tilted design of the first baffle strip 22, it will not generate significant pressure when in contact with the rear end of drawer 1, which has undergone some deformation. Since the cover body 21 and the first baffle strip 22 are separate components, the first baffle strip 22 can be made of a soft material to avoid interference affecting the normal sliding of drawer 1. The second baffle strip 23 can be designed similarly to the first baffle strip 22, and will not be described further here.
