Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a food storage drawer and refrigerator. Background Technology

[0002] In modern family life, the refrigerator, as one of the core kitchen appliances, directly affects the quality of stored food and the user experience through its preservation function. Humidity control inside the crisper drawer is a key factor in maintaining the freshness of fruits and vegetables. Vegetables and fruits continue to respire after being harvested; if the ambient humidity is too low, moisture will evaporate too quickly, causing them to dry out and shrivele. Conversely, excessive humidity can lead to mold or rot. Therefore, the crisper drawer needs to have humidity regulation capabilities to adapt to the storage needs of different fruits and vegetables.

[0003] In related technologies, food storage drawers typically control humidity through a humidity-regulating structure on the lid. Users adjust the ventilation area of ​​the drawer by rotating this structure, thereby altering the airflow within the drawer. Specifically, the adjustment structure includes a knob, a humidity-regulating plate, and a sealing strip. The knob is located at the top of the lid, the humidity-regulating plate is located below the lid and connected to the knob, and the sealing strip is fixed to the front of the humidity-regulating plate. When the user rotates the knob about its height, the knob causes the humidity-regulating plate to rotate about its depth, thus changing the contact or gap between the sealing strip and the inner wall of the drawer, thereby altering the ventilation area.

[0004] However, the adjustment range of the food storage drawer is relatively small. Utility Model Content

[0005] This application provides a food storage drawer and a refrigerator, wherein the food storage drawer has a large adjustment range.

[0006] This application provides a food storage drawer, comprising:

[0007] A drawer box with a storage compartment that has an opening at the top;

[0008] A lid assembly, located on the top of the drawer box, includes:

[0009] A cover is provided on top of the drawer box, and a first guide structure is provided at the bottom of the cover. The extension direction of the first guide structure is consistent with the depth direction of the drawer box.

[0010] The drive assembly connects to the cover plate;

[0011] A humidity control component is connected to a drive component. The humidity control component is provided with a second guide structure that matches the first guide structure. The second guide structure is movably connected to the first guide structure. The second guide structure and the first guide structure are configured to limit the movement direction of the humidity control component and its position along the height direction of the drawer box.

[0012] The drive component moves the humidity control component along the depth direction, and the second guide structure moves relative to the first guide structure along the depth direction, so that the humidity control component moves closer to or further away from the inner wall of the drawer box.

[0013] This application provides a food storage drawer including a drawer box and a lid assembly. The lid assembly includes a cover plate, a drive assembly, and a humidity regulating assembly. The cover plate is positioned above the drawer box, and the drive assembly is connected to the cover plate. The humidity regulating assembly is connected to the drive assembly, which drives the humidity regulating assembly to move along the depth direction, allowing it to move closer to or away from the inner wall of the drawer box. Since horizontal movement is not limited by the distance between the humidity regulating assembly and the cover plate along the height direction, the adjustment range can be large. The elimination of two-stage rotation improves the user experience. Furthermore, a first guide structure is provided at the bottom of the cover plate, extending in the same direction as the depth of the drawer box. The humidity regulating assembly has a second guide structure that matches the first guide structure, and the second guide structure is movably connected to the first guide structure. The second guide structure moves relative to the first guide structure along the depth direction. The first and second guide structures limit the movement direction and position of the humidity regulating assembly along the height of the drawer box, thus ensuring smooth movement of the humidity regulating assembly.

[0014] In some embodiments, the number of second guide structures is at least two, the at least two second guide structures are disposed on opposite sides of the drive assembly along the width direction of the drawer box, and the at least two second guide structures are close to both ends of the humidity regulating assembly along the width direction of the drawer box.

[0015] The number of first guide structures is at least two, and at least two first guide structures are connected one-to-one with at least two second guide structures.

[0016] In this way, the force span formed by the support near both ends is larger, and the humidity control component is less likely to shake or sway.

[0017] In some embodiments, the first guide structure includes a first guide portion and a second guide portion, the top of the first guide portion is connected to the bottom of the cover plate, the bottom of the second guide portion is connected to the second guide portion, and the top of the second guide portion is provided with a first guide surface, which is parallel to the horizontal plane.

[0018] The second guide structure includes a third guide section and a fourth guide section. The third guide section is connected to the humidity control component. The top of the third guide section is connected to the bottom of the fourth guide section. The bottom of the fourth guide section is provided with a second guide surface, which is parallel to the horizontal plane and abuts against the first guide surface.

[0019] In this way, the connection between the first guide structure and the second guide structure is achieved by the second guide surface abutting against the first guide surface, resulting in high connection efficiency.

[0020] In some embodiments, the driving component includes:

[0021] An operating component is inserted into the cover plate, with the operating component portion located at the top of the cover plate, and the operating component is movably connected to the cover plate;

[0022] The transmission module is connected to the operating components and the humidity control assembly, respectively.

[0023] The operating component drives the humidity control assembly to move along the depth direction via the transmission module.

[0024] In this way, by setting up operating components and transmission modules, users can adjust the ventilation area as needed through mechanical operation, which is highly reliable. Moreover, compared to setting up motors and other devices for driving, it is lower in cost and occupies less space.

[0025] In some embodiments, the operating member rotates relative to the cover plate, and the axis of the operating member is aligned with the height direction of the drawer box.

[0026] In this way, adjustment is performed by rotation, resulting in a smaller range of motion for the operating components and a smaller footprint. Furthermore, the rotation method allows for setting the transmission ratio via the transmission module, thereby improving the accuracy of the adjustment.

[0027] In some embodiments, the transmission module includes:

[0028] Gears, connected to the operating components;

[0029] The rack meshes with the gear and is connected to the humidity control assembly.

[0030] In this way, the linear motion characteristics of the gear and rack allow the sliding distance of the humidity control component to be significantly greater than the flip angle of a traditional rotary structure, thereby expanding the adjustment range of the ventilation area. At the same time, it effectively avoids the error accumulation caused by multi-stage rotary transmission, ensuring the adjustment accuracy of the ventilation area. Furthermore, the gear and rack transmission path is direct and stable, which facilitates precise control of the humidity inside the drawer.

[0031] In some embodiments, the operating element and gear are secured by fasteners;

[0032] And / or, the operating element is provided with a first limiting structure, and the gear is provided with a second limiting structure that matches the first limiting structure. The first limiting structure and the second limiting structure are connected to limit the position of the gear relative to the operating element in the circumferential direction.

[0033] And / or, the operating element is provided with a first positioning structure, and the gear is provided with a second positioning structure that matches the first positioning structure. The first positioning structure is connected to the second positioning structure to limit the position of the gear relative to the operating element along the height direction of the drawer box.

[0034] This restricts the circumferential position of the gear and the operating element, preventing relative rotation between them. It also restricts the position of the gear relative to the operating element along the vertical direction.

[0035] In some embodiments, the humidity control component includes:

[0036] A humidity regulating plate is connected to the drive assembly, and the humidity regulating plate is provided with a third positioning structure;

[0037] A seal is disposed at one end of the humidity regulating plate along the depth direction. The seal includes:

[0038] The main body structure is provided with an installation cavity, and the humidity regulating plate is inserted into the installation cavity;

[0039] The fourth positioning structure is set on the main body structure. The fourth positioning structure matches the third positioning structure and is connected to the third positioning structure to limit the position of the seal relative to the humidity regulating plate along the depth direction.

[0040] At least two clamping structures are provided in the mounting cavity, and the at least two clamping structures are respectively provided in the top wall and bottom wall of the mounting cavity.

[0041] In this way, the connection between the humidity regulating plate and the seal is highly reliable, and the seal is not easy to fall off.

[0042] In some embodiments, the lid assembly further includes a glass panel that covers at least a portion of the top wall of the lid.

[0043] The glass panel is equipped with a clearance section for the clearance drive assembly.

[0044] In this way, the glass panel can serve a decorative purpose, enhancing the aesthetics. Furthermore, the glass panel has a low visual and tactile temperature, providing a cool sensation to the user and thus improving the user experience.

[0045] This application provides a refrigerator, including:

[0046] The container is designed with storage compartments.

[0047] The door is rotatably connected to the cabinet to open or close the storage compartment;

[0048] The aforementioned food storage drawer is located inside the storage room.

[0049] This allows for a wider range of adjustments to the crisper drawer in the refrigerator. Attached Figure Description

Detailed Implementation

[0069] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0070] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0071] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0072] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0073] In related technologies, the adjustment structure includes a knob, a humidity regulating plate, and a sealing strip. The knob is located at the top of the cover, and the humidity regulating plate is located below the cover, connected to the knob. The sealing strip is fixed to the front side of the humidity regulating plate. The user rotates the knob about the height axis, causing the humidity regulating plate to rotate about the depth axis. This changes the contact or gap between the sealing strip and the inner wall of the drawer box, thus altering the ventilation area. When the humidity regulating plate is in a horizontal position, the sealing strip is in contact with the inner wall of the drawer box, creating a seal and effectively preventing moisture from entering the drawer box. When the front end of the humidity regulating plate rotates downwards, a gap appears between the sealing strip and the inner wall of the drawer box, allowing moisture to enter.

[0074] However, due to the limited spacing between the humidity regulating plate and the cover along the height direction, after the front end of the humidity regulating plate rotates downwards at a certain angle, the rear end of the humidity regulating plate will contact the cover, thus preventing further rotation. The gap between the sealing strip and the inner wall of the drawer box is also small. For example, the maximum gap between the sealing strip and the inner wall of the drawer box along the depth direction is 3mm. Therefore, the adjustment range of the food storage drawer is limited.

[0075] Furthermore, because the adjustment range is only 3mm, it is relatively small. If manufacturing errors occur during assembly, resulting in the sealing strip having too small a contact area with the inner wall of the drawer box, or failing to make contact, or the humidity regulating plate remaining in contact even after being flipped, the humidity regulating effect will be ineffective. Therefore, production efficiency is low during mass production, requiring multiple checks of the dimensions of each component, which can easily lead to quality problems.

[0076] Furthermore, the force is transmitted to the humidification plate by rotating the knob, which then rotates it. In other words, it requires two stages of rotation. These two stages of rotation amplify the feeling of "playing, sticking, and effort" during operation through the accumulation of gaps, the superposition of friction, and the loss of force transmission, ultimately resulting in a poor user experience and negatively impacting the user's experience.

[0077] To address the aforementioned technical problems, this application provides a food preservation drawer and a refrigerator. The food preservation drawer includes a drawer box and a lid assembly. The lid assembly includes a cover plate, a drive assembly, and a humidity regulating assembly. The cover plate is positioned above the drawer box, and the drive assembly is connected to the cover plate. The humidity regulating assembly is connected to the drive assembly, which drives the humidity regulating assembly to move along the depth direction, allowing it to move closer to or away from the inner wall of the drawer box. Since horizontal movement is not limited by the distance between the humidity regulating assembly and the cover plate along the height direction, the adjustment range can be large. The elimination of two-stage rotation improves the user experience.

[0078] Furthermore, a first guide structure is provided at the bottom of the cover, and the extension direction of the first guide structure is consistent with the depth direction of the drawer box. The humidity regulating component is provided with a second guide structure that matches the first guide structure, and the second guide structure is movably connected to the first guide structure. The second guide structure moves relative to the first guide structure along the depth direction. The first and second guide structures can limit the movement direction of the humidity regulating component and its position along the height direction of the drawer box, thereby making the movement of the humidity regulating component smooth.

[0079] See Figure 1 As shown, this application provides a refrigerator. The refrigerator can be a direct-cooling refrigerator or a frost-free refrigerator.

[0080] The refrigerator includes a cabinet 100. The cabinet 100 is configured to form a storage compartment.

[0081] See Figure 1 and Figure 2 As shown, the housing 100 includes an outer shell, a housing liner, and a press chamber.

[0082] The outer casing has a first receiving cavity with a first pick-up and drop-out port and a second pick-up and drop-out port, which are respectively located on opposite sides of the outer casing in the depth direction of the housing 100. The first pick-up and drop-out port can be located on the front side of the outer casing, and the second pick-up and drop-out port can be located on the rear side of the outer casing.

[0083] The compressor compartment is located inside the outer shell, and its opening is opposite to the second access port, allowing the compressor and condenser to be placed inside the compressor compartment via the second access port and the opening. The storage liner is located inside the outer shell and has at least one storage compartment. The storage liner has a third access port, which is opposite to the first access port, allowing items to be placed inside the storage compartment via the third access port and the first access port.

[0084] A foam layer is filled between the inner liner, outer shell, and compressor compartment. The foam layer is used to insulate the storage compartment, thereby ensuring the cooling effect inside the storage compartment.

[0085] The storage room can be at least one, and when there is only one storage room, it can be any one of a refrigerator, freezer, or variable temperature compartment. When there are two or more storage rooms, the multiple storage rooms can include at least one or more of a refrigerator, freezer, or variable temperature compartment.

[0086] See Figure 1 As shown, the refrigerator includes a door 200, which is rotatably connected to the cabinet 100 to open or close the storage compartment.

[0087] The door 200 is an openable cover located on the front of the cabinet 100 to close and open the storage compartment, allowing users to access items inside. It should be noted that there can be one, two, or more doors 200.

[0088] In some embodiments, the door 200 includes a door frame. The door frame may have two side frames disposed opposite each other along the width direction of the door. The door frame may include a connecting plate located between the two side frames.

[0089] The door body 200 includes an end cap, which is disposed at the end of the door frame along the height direction and is rotatably connected to the housing 100. A limiting member is disposed at the end of the end cap opposite to the door frame along the height direction. The height direction is... Figure 3 The direction indicated by the Z-axis.

[0090] Specifically, there are two end caps, including an upper end cap and a lower end cap. The upper end cap is located at the top of the door frame, and the lower end cap is located at the bottom of the door frame.

[0091] The door body 200 includes a panel that can be attached to the outside of the door frame to form the appearance of the door body.

[0092] The door body 200 includes an inner door liner, which is located on the inside of the door frame.

[0093] The door body 200 includes a door insulation component, which can be installed in the gap between the door inner liner and the door frame. The door insulation component insulates the storage compartment to minimize heat exchange between the storage compartment and the outside of the refrigerator, thus ensuring the refrigerator's cooling effect. The door insulation component can be a foam layer.

[0094] The door body 200 includes a door liner disposed on the side of the inner door panel opposite to the panel. The door liner is wrapped around the periphery of the inner door panel. The door liner abuts against the housing 100, thereby improving the sealing between the door body and the housing 100.

[0095] A refrigerator includes a refrigeration system, which may include a compressor, a condenser, a throttling device, and an evaporator. The compressor, condenser, throttling device, and evaporator are connected in series via piping, through which refrigerant flows. The compressor and condenser may be located in the compressor compartment, while the evaporator is located in the storage compartment.

[0096] When the compressor is working, low-temperature, low-pressure refrigerant is drawn into the compressor and compressed into high-temperature, high-pressure superheated gas in the compressor cylinder before being discharged into the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, and its temperature continuously decreases, gradually being cooled into room-temperature, high-pressure saturated vapor, and further cooled into saturated liquid. The pressure of the refrigerant remains almost constant throughout the entire condensation process.

[0097] The throttling device may include a pressure reducing tube or an electronic expansion valve. In this application, the throttling device is described as including a pressure reducing tube as an example. The pressure reducing tube is low in cost and is not prone to abnormal failure.

[0098] After condensation, the saturated refrigerant liquid is throttled and depressurized through a pressure reducing pipe, transforming into a room-temperature, low-pressure wet vapor. This wet vapor then absorbs heat and vaporizes in the evaporator, lowering not only the temperature of the evaporator and its surroundings but also transforming the refrigerant into a low-temperature, low-pressure gas. The evaporator cools the air inside the storage compartment, lowering its temperature. The refrigerant exiting the evaporator returns to the compressor, repeating the process to ensure continuous cooling of the air inside the storage compartment, thus maintaining the set temperature.

[0099] See Figure 2 As shown, in some embodiments, the refrigerator includes a crisper drawer 300 located within the storage compartment. Specifically, the crisper drawer 300 may be located in the refrigerator compartment.

[0100] See Figure 3 As shown, this application provides a food storage drawer 300, which includes a drawer box 310. The drawer box 310 is provided with a storage cavity with a top opening. The drawer box 310 can be used to store fruits and vegetables. The drawer box 310 is slidably connected to the cabinet 100, and the user can take out and put in fruits and vegetables through the top opening.

[0101] See Figure 4 As shown, the food storage drawer 300 includes a lid device 320. The lid device 320 is disposed on the top of the drawer box 310. The lid device 320 is used to adjust the humidity inside the drawer box 310. The projected area of ​​the lid device 320 towards the horizontal plane is not less than the projected area of ​​the drawer box 310 towards the horizontal plane.

[0102] See Figure 3 and Figure 5 As shown, in some embodiments, the lid device 320 includes a cover plate 321. The cover plate 321 is disposed above the drawer box 310.

[0103] In some embodiments, the cover plate 321 can be made of HIPS (High Impact Polystyrene). Compared to ordinary polystyrene, HIPS has significantly improved impact resistance, especially maintaining a certain degree of toughness at low temperatures, making it less brittle and suitable for applications requiring minor impacts. Furthermore, it has good flowability, is easy to mold, and can be processed through various processes such as injection molding, extrusion, and thermoforming, resulting in high production efficiency and suitability for mass production. It also has low molding shrinkage and good dimensional stability, enabling the production of high-precision products. Specifically, the lid can be processed using injection molding.

[0104] In some embodiments, a reinforcing rib 3212 is provided at the bottom of the cover plate 321, and the reinforcing rib 3212 is used to reduce the deformation of the cover plate 321.

[0105] See Figure 7 and Figure 8 As shown, in some embodiments, the lid assembly 320 includes a drive assembly 322. The drive assembly 322 is connected to the lid 321. The drive assembly 322 is used to drive the humidity regulating assembly 323 to move, thereby adjusting the ventilation area of ​​the drawer box 310.

[0106] In some embodiments, the lid device 320 includes a humidity regulating component 323. The humidity regulating component 323 is connected to the drive component 322. The humidity regulating component 323 is used to abut against or have a gap with the inner wall of the drawer box 310, and the ventilation area is adjusted by changing the gap.

[0107] Specifically, the user can drive the humidity regulating component 323 to move along the depth direction via the drive component 322, so that the humidity regulating component 323 moves closer to or further away from the inner wall of the drawer box 310. Here, the depth direction is the direction shown by the Y-axis.

[0108] It is understood that the food storage drawer 300 includes a drawer box 310 and a lid assembly 320. The lid assembly 320 includes a cover plate 321, a drive assembly 322, and a humidity regulating assembly 323. The cover plate 321 is positioned above the drawer box 310, and the drive assembly 322 is connected to the cover plate 321. The humidity regulating assembly 323 is connected to the drive assembly 322. By operating the drive assembly 322, the user moves the humidity regulating assembly 323 along the depth direction, allowing it to move closer to or away from the inner wall of the drawer box 310. Since horizontal movement is not limited by the distance between the humidity regulating assembly 323 and the cover plate 321 along the height direction, the adjustment range can be large. The elimination of two-stage rotation improves the user experience.

[0109] See Figure 6 and Figure 7 As shown, in some embodiments, a first guide structure 3211 is provided at the bottom of the cover plate 321, and the extension direction of the first guide structure 3211 is consistent with the depth direction of the drawer box 310. The depth direction is the direction indicated by the Y-axis.

[0110] In some embodiments, the humidity regulating component 323 is provided with a second guide structure 3231a that matches the first guide structure 3211, and the second guide structure 3231a is movably connected to the first guide structure 3211. The movable connection between the second guide structure 3231a and the first guide structure 3211 restricts the movement direction of the humidity regulating component 323 and its position along the height direction of the drawer box 310. The height direction is the direction indicated by the Z-axis.

[0111] Specifically, the second guide structure 3231a moves relative to the first guide structure 3211 along the depth direction. The second guide structure 3231a and the first guide structure 3211 can limit the downward position of the humidity control assembly 323 along the height direction.

[0112] Understandably, the bottom of the cover 321 is provided with a first guide structure 3211, the extension direction of which is consistent with the depth direction of the drawer box 310. The humidity regulating assembly 323 is provided with a second guide structure 3231a that matches the first guide structure 3211, and the second guide structure 3231a is movably connected to the first guide structure 3211. The second guide structure 3231a moves relative to the first guide structure 3211 along the depth direction. The first guide structure 3211 and the second guide structure 3231a can limit the movement direction of the humidity regulating assembly 323 and its position along the height direction of the drawer box 310, thereby making the movement of the humidity regulating assembly 323 smooth.

[0113] See Figure 9 and Figure 10 As shown, in some embodiments, the number of second guide structures 3231a is at least two, and the at least two second guide structures 3231a are disposed on opposite sides of the drive assembly 322 along the width direction of the drawer box 310. The number of first guide structures 3211 is at least two, and the at least two first guide structures 3211 are connected to the at least two second guide structures 3231a in a one-to-one correspondence. The width direction can be the direction shown by the X-axis.

[0114] For example, the number of second guide structures 3231a can be two, three, or four. Correspondingly, the number of first guide structures 3211 can be two, three, or four. The following description assumes that there are two first guide structures 3211 and two second guide structures 3231a.

[0115] The two second guide structures 3231a are located near the two ends of the humidity regulating assembly 323 along the width direction of the drawer box 310. The greater force span formed by these near-end support points makes the humidity regulating assembly 323 less prone to wobbling or swaying. It should be noted that the outer wall of the second guide structure 3231a can be flush with the outer wall of the humidity regulating plate 3231 in the humidity regulating assembly 323. Alternatively, the outer wall of the second guide structure 3231a can have a small gap with the outer wall of the humidity regulating plate 3231 in the humidity regulating assembly 323, for example, a gap of less than 50 mm.

[0116] In some embodiments, two second guide structures 3231a are symmetrically arranged about the rack along the width direction of the drawer box 310. This helps to improve the balance of forces on the humidity regulating plate 3231 in the humidity regulating assembly 323.

[0117] See Figure 9 As shown, in some embodiments, the first guide structure 3211 includes a first guide portion 3211a and a second guide portion 3211b. The top of the first guide portion 3211a is connected to the bottom of the cover plate 321, and the bottom of the second guide portion 3211b is connected to the second guide portion 3211b. The top of the second guide portion 3211b is provided with a first guide surface 3211c, which is parallel to the horizontal plane. Thus, the first guide structure 3211 has a simple structure and is easy to manufacture. Specifically, the first guide portion 3211a and the second guide portion 3211b can be arranged in an L-shape.

[0118] See Figure 10 As shown, the second guide structure 3231a includes a third guide portion 3231b and a fourth guide portion 3231c. The third guide portion 3231b is connected to the humidity regulating component 323. The top of the third guide portion 3231b is connected to the bottom of the fourth guide portion 3231c. A second guide surface 3231d is provided at the bottom of the fourth guide portion 3231c. The second guide surface 3231d is parallel to the horizontal plane and abuts against the first guide surface 3211c. Thus, the first guide structure 3211a has a simple structure and is easy to manufacture. Specifically, the first guide portion 3211a and the second guide portion 3211b can be arranged in an inverted L-shape.

[0119] It is understandable that the connection between the first guide structure 3211 and the second guide structure 3231a is achieved by the second guide surface 3231d abutting against the first guide surface 3211c, which results in high connection efficiency.

[0120] Furthermore, when transmission is achieved via gears and racks, the position of the humidity regulating plate 3231 in the humidity regulating assembly 323 is easily adjustable along both the width and height directions, thus helping to ensure the accuracy of the rack's position relative to the gears. For example, the height direction can be adjusted using shims on the second guide surface 3231d and the first guide surface 3211c. The width direction can be adjusted by having a gap between the fourth guide portion 3231c and the first guide portion 3211a.

[0121] In some embodiments, the drive assembly 322 includes an operating element 3221. The operating element 3221 is inserted into the cover plate 321, with a portion of the operating element 3221 located on the top of the cover plate 321, and the operating element 3221 is movably connected to the cover plate 321. The operating element 3221 is used for operation by a user.

[0122] The drive assembly 322 includes a transmission module 3222. The transmission module 3222 transmits the user's actions to the humidity control assembly 323. The transmission module 3222 is connected to both the operating member 3221 and the humidity control assembly 323. The operating member 3221 drives the humidity control assembly 323 to move along the depth direction via the transmission module 3222.

[0123] Understandably, by setting up the operating component 3221 and the transmission module 3222, users can adjust the ventilation area as needed through mechanical operation, which offers high reliability. Moreover, compared to using motors or other devices for drive, it is lower in cost and occupies less space.

[0124] In some embodiments, the operating member 3221 slides relative to the cover plate 321, and the operating member 3221 slides relative to the cover plate 321 along the depth direction.

[0125] In some embodiments, the operating member 3221 rotates relative to the cover plate 321, and the axis of the operating member 3221 is aligned with the height direction of the drawer box 310. Specifically, the operating member 3221 can be a knob. It is understood that by adjusting by rotation, the range of motion of the operating member 3221 and the space occupied are relatively small. Moreover, by using rotation, the transmission ratio can be set through the transmission module 3222, thereby improving the accuracy of adjustment.

[0126] In some embodiments, the operating member 3221 and / or the cover 321 are provided with markings. For example, they may be marked "large" and "small". When the operating member 3221 is rotated clockwise, the marking on the operating member 3221 is in the "large" position. At this time, the distance between the humidity regulating component 323 and the inner wall of the drawer box 310 is at its maximum, and moisture enters the drawer box 310. See also... Figure 5As shown, the maximum value of the distance f between the humidity regulating component 323 and the inner wall of the drawer box 310 is not less than 8mm. Similarly, rotating the operating component 3221 counterclockwise sets the indicator mark of the operating component 3221 to the "small" position. At this time, the humidity regulating component 323 is pressed tightly against the inner wall of the drawer box 310, preventing moisture from entering the drawer box 310.

[0127] See Figure 8 As shown, in some embodiments, the transmission module 3222 includes a gear 3222a and a rack 3222b, with the gear 3222a connected to the operating member 3221. The rack 3222b meshes with the gear 3222a and is connected to the humidity control assembly 323.

[0128] In this way, the linear motion characteristics of gears 3222a and rack 3222b allow the sliding distance of the humidity control component 323 to be significantly greater than the flip angle of a traditional rotary structure, thereby expanding the adjustment range of the ventilation area. Simultaneously, it effectively avoids the accumulation of errors caused by multi-stage rotary transmission, ensuring the adjustment accuracy of the ventilation area. Furthermore, the transmission path of gears 3222a and rack 3222b is direct and stable, which facilitates precise control of the humidity inside the drawer box 310.

[0129] The rack 3222b can be fixedly positioned at the middle of the humidity regulating assembly 323 along the width direction, where the width direction is indicated by the X-axis. The rack 3222b extends in the same direction as the depth direction, where the depth direction is indicated by the Y-axis.

[0130] Specifically, the rack 3222b and the humidity regulating plate 3231 can be integrated into one unit, thereby reducing assembly steps and improving production efficiency.

[0131] In other embodiments, the transmission module includes a ball screw pair and a bevel gear. One bevel gear is mounted on the operating member 3221, and another meshing bevel gear (achieving 90° reversal) is mounted on one end of the horizontally arranged screw. The screw nut is fixedly connected to the humidity control assembly 323. During operation, the rotation of the operating member 3221 drives the bevel gear to rotate, which in turn drives the ball screw to rotate, causing the screw nut to move horizontally along the screw.

[0132] See Figure 11 and Figure 12 As shown, in some embodiments, the operating element 3221 and the gear 3222a are fixed by fasteners. Specifically, the operating element 3221 and the gear 3222a can be fixed by screws. A fixing post is provided in the central area of ​​the operating element 3221, and a first mounting hole is provided on the fixing post. A second mounting hole is provided on the gear 3222a. The screw passes through the second mounting hole and is inserted into the first mounting hole, thereby achieving a fixed connection between the operating element 3221 and the gear 3222a. The screw can be made of stainless steel, which is not easily corroded.

[0133] In some embodiments, gear 3222a may be made of HIPS. Gear 3222a may be manufactured by injection molding.

[0134] In some embodiments, the operating element 3221 may be made of HIPS. The operating element 3221 may be manufactured by injection molding.

[0135] See Figure 8 and Figure 11 As shown, in some embodiments, the top of the operating member 3221 has a recess. A decorative member 324 is embedded in the top of the operating member 3221. Specifically, the decorative member 324 can be connected to the operating member 3221 by adhesive bonding. For example, it can be bonded using double-sided adhesive. The decorative member 324 serves an aesthetic purpose.

[0136] In some embodiments, the decorative element 324 may be made of HIPS. The decorative element 324 may be manufactured by injection molding.

[0137] See Figure 11 and Figure 12 As shown, in some embodiments, the operating member 3221 is provided with a first limiting structure 3221a, and the gear 3222a is provided with a second limiting structure 3222c that matches the first limiting structure 3221a. The first limiting structure 3221a and the second limiting structure 3222c are connected to limit the position of the gear 3222a relative to the operating member 3221 in the circumferential direction. One of the first limiting structure 3221a and the second limiting structure 3222c can be a limiting protrusion, and the other can be a limiting groove that matches the limiting protrusion. The limiting protrusion is inserted into the limiting groove, thereby limiting the position of the gear 3222a and the operating member 3221 in the circumferential direction and preventing relative rotation between them.

[0138] See Figure 11 and Figure 12 As shown, in some embodiments, the operating member 3221 is provided with a first positioning structure 3221b, and the gear 3222a is provided with a second positioning structure 3222d that matches the first positioning structure 3221b. The first positioning structure 3221b and the second positioning structure 3222d are connected to limit the position of the gear 3222a relative to the operating member 3221 along the height direction of the drawer box 310. One of the first positioning structure 3221b and the second positioning structure 3222d is a hook, and the other is a groove that matches the hook. The hook and the groove are connected to limit the position of the gear 3222a relative to the operating member 3221 along the height direction. The height direction is the direction indicated by the Z-axis.

[0139] See Figure 3 and Figure 5 As shown, in some embodiments, the humidity control assembly 323 includes a humidity control plate 3231.

[0140] The humidity control assembly 323 includes a seal 3232, which is disposed at one end of the humidity control plate 3231 along the depth direction. The seal 3232 is disposed at the front end of the humidity control plate 3231. The seal 3232 extends along the width direction.

[0141] The material of seal 3232 can be PVC (Polyvinyl Chloride). Seal 3232 can be manufactured by co-extrusion of soft and hard materials.

[0142] See Figure 13 In some embodiments, the seal 3232 includes a body structure 3232a. The body structure 3232a is provided with a mounting cavity, and the humidity regulating plate 3231 is inserted into the mounting cavity. The body structure 3232a may be formed by hard extrusion.

[0143] In some embodiments, the seal 3232 includes an airbag 3232b, which is connected to the body structure 3232a and is used to abut against the inner wall of the drawer box 310. The airbag 3232b may be formed by soft extrusion.

[0144] See Figure 3 , Figure 5 and Figure 13 In some embodiments, the humidity regulating plate 3231 is connected to the drive assembly 322, and the humidity regulating plate 3231 is provided with a third positioning structure 3231e. The seal 3232 includes a fourth positioning structure 3232c, which is disposed on the body structure 3232a. The fourth positioning structure 3232c matches the third positioning structure 3231e and is connected to the third positioning structure 3231e to limit the position of the seal 3232 relative to the humidity regulating plate 3231 along the depth direction.

[0145] In this design, one of the fourth positioning structure 3232c and the third positioning structure 3231e is a positioning protrusion, and the other is a positioning groove that matches the positioning protrusion. The positioning protrusion and the positioning groove are connected to each other, thereby improving the connection reliability between the humidity regulating plate 3231 and the seal 3232. The fourth positioning structure 3232c can be manufactured by hard extrusion.

[0146] In some embodiments, the seal 3232 includes at least two clamping structures 3232d. The clamping structures 3232d are disposed in the mounting cavity, with at least two clamping structures 3232d respectively disposed on the top and bottom walls of the mounting cavity. The clamping structures 3232d clamp the humidity regulating plate 3231, thereby improving the connection reliability between the humidity regulating plate 3231 and the seal 3232. The clamping structures 3232d can be formed by hard extrusion.

[0147] See Figure 8 and Figure 14 As shown, in some embodiments, the lid device 320 further includes a glass panel 325. The glass panel 325 can serve a decorative purpose, enhancing aesthetics. Moreover, the glass panel 325 has a low visual and tactile temperature, providing a cool sensation to the user and thus improving the user experience.

[0148] The glass panel 325 covers at least a portion of the top wall of the cover plate 321. For example, the glass panel 325 may cover the entire top wall of the cover plate 321. Alternatively, the glass panel 325 may cover the front portion of the cover plate 321 along its depth direction. The glass panel 325 and the cover plate may be bonded together, for example, with double-sided adhesive. The glass panel 325 is located near the front side of the cover plate 321 along its depth direction.

[0149] The glass panel 325 is provided with a clearance part 3251 of the clearance drive assembly 322.

[0150] In some embodiments, the glass panel 325 is made of tempered glass, which is not easily damaged.

[0151] In some embodiments, the corners of the glass panel 325 are rounded or chamfered to improve smoothness and reduce the risk of injury to the user. For example, the top and bottom edges are both chamfered at 45° by 0.5mm.

[0152] In some embodiments, an opaque coating may be provided on the bottom of the glass panel 325 to effectively prevent the viewing angle from penetrating the glass panel 325.

[0153] The following describes the overall installation process of the food storage drawer:

[0154] The glass panel 325 is adhered to the cover plate 321. The operating component 3221 is installed on the glass panel 325, and the gear 3222a is fixed to the mounting component using self-tapping screws. The integrally formed rack 3222b and humidity regulating plate 3231 are connected to the cover plate 321 and gear 3222a, respectively. The decorative component 324 is installed on the operating component 3221, thus completing the installation of the box cover assembly 320. The box cover assembly 320 is installed inside the box.
