Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigerator. Background Technology

[0002] A currently disclosed refrigerator has a refrigeration space with a crisper drawer inside. The drawer has a cover on its top side, and a water tray is mounted on the cover. The water tray has a misting plate that provides humidifying mist into the drawer to improve the preservation of food. The water tray is mounted on the cover in an up-and-down manner. Removing the water tray requires prying up one end and then pulling it upwards, which is inconvenient.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0004] In view of the problems pointed out in the background art, this utility model proposes a refrigerator that facilitates the disassembly and assembly of the water tank.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0006] In some embodiments of this application, a refrigerator is provided, wherein the inner liner forms a refrigerator compartment; a fresh food drawer is pulled out and disposed in the refrigerator compartment, the fresh food drawer has a drawer cavity formed therein, a slot is provided on the side wall of the fresh food drawer, and the top side of the slot is open; a water box assembly is detachably disposed in the slot, the water box assembly is inserted downward into the slot or removed upward from the slot through the top side opening of the slot, and the water box assembly is configured to provide humidifying mist to the drawer cavity.

[0007] The above technical solution has the following advantages or beneficial effects: The refrigerator of this application has a slot with an open top on the side wall of the fresh food drawer, so that the water box assembly can be directly inserted vertically downward or taken out upward through the open top. The structure is adapted to the natural operating trajectory of the human body, and the user does not need to deliberately adjust the angle of force application, which is convenient for operation.

[0008] The detachable design of this application allows the water tank assembly to be completely removed from the refrigeration space, facilitating thorough cleaning or disinfection by the user. Furthermore, the open slot design allows for direct observation of the internal cleanliness, reducing blind spots and indirectly improving the cleanliness of the food preservation environment, thus ensuring the stability of the atomized humidification effect.

[0009] In some embodiments of this application, the water box assembly includes a water box body with a water storage cavity formed therein; the water box assembly also includes a water outlet, the water box body has an installation port, and the water outlet is located at the installation port; the slot is provided with a spray section, which is configured to provide humidifying mist into the drawer cavity.

[0010] The water outlet is configured to guide water from the water storage chamber to the spray section when the water box body is installed in the slot; the water outlet is also configured to close when the water box body is removed from the slot to prevent water from flowing out of the water storage chamber.

[0011] Another technical solution described above has the following advantages or beneficial effects: When the water box assembly is installed in the slot, the water outlet and the spray section automatically connect, stably guiding the water in the water storage chamber to the spray section (such as the atomizing plate), ensuring a continuous water supply to the spray section and guaranteeing a stable output of humidifying mist. This directional guidance design avoids the problem of unstable water supply caused by the traditional water box relying on gravity-driven natural dripping, keeping the humidity in the drawer cavity uniform and improving the food preservation effect.

[0012] The water outlet features an adaptive function of "open during installation, closed during removal," a core design feature that solves the leakage problem when traditional water tanks are disassembled. When the water tank assembly is removed from the slot, the water outlet automatically closes, effectively preventing residual water in the storage chamber from flowing out and avoiding water dripping into drawers or the refrigerator compartment, thus reducing the user's cleaning burden. For example, when a user temporarily removes the water tank to check the water level or for cleaning, even if there is water in the storage chamber, there is no need to empty it beforehand; the operation can be performed directly, improving ease of use.

[0013] In some embodiments of this application, the water outlet includes a first mounting base, the first mounting base is disposed at the mounting port, a water flow cavity is formed in the first mounting base, a water flow outlet is disposed on the first mounting base, the water flow cavity communicates with the water flow outlet, and the water flow cavity communicates with the spray section;

[0014] The water outlet also includes a moving part, which passes through the water inlet, and a water outlet gap is formed between the moving part and the water inlet;

[0015] The water outlet section also includes an elastic element, which is disposed in the water flow cavity and is configured to apply a force to the moving element, causing the moving element to move in a direction away from the water storage cavity.

[0016] The water outlet section also includes a sealing member connected to the moving member. The sealing member is configured to block the water outlet gap when the moving member moves away from the water storage chamber, and the sealing member is also configured to open the water outlet gap when the moving member moves towards the water storage chamber.

[0017] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0018] The water-carrying chamber within the first mounting bracket provides a directional channel for water flow. Its two open ends connect to the water storage chamber (through the water outlet) and the spray unit, respectively, forming a complete water circuit of "water storage chamber - water outlet - water-carrying chamber - spray unit". This closed pipeline design reduces evaporation and contamination of water during transmission, while avoiding the risk of corrosion caused by direct contact between water and other components of the water box, thus ensuring the cleanliness of the water supply.

[0019] When the water box assembly is inserted into the slot, the end of the moving part away from the water storage chamber contacts the spray unit and is subjected to its pressure, moving towards the water storage chamber. At this time, the water outlet gap opens due to the displacement of the moving part, allowing water in the water storage chamber to flow smoothly into the water outlet chamber through this gap. When the water box assembly is removed, the moving part returns to its original position under the action of the elastic element, and the water outlet gap closes accordingly. This gap design, which automatically changes according to the installation state of the water box, achieves "on-demand water supply," eliminating the need for manual valve operation by the user and simplifying the usage process.

[0020] The sealing component is connected to the moving component and controls the opening and closing of the water outlet gap as the moving component moves. It is the core component for the leak-proof function of the water outlet. When the water box assembly is removed, the moving component moves away from the water storage cavity under the action of the elastic component. The sealing component moves with it and fits tightly against the edge of the water outlet, completely sealing the water outlet gap. At this time, even if there is water in the water storage cavity, it cannot flow out through the water outlet, fundamentally solving the leakage problem when traditional water boxes are disassembled.

[0021] In some embodiments of this application, the moving part includes a first moving part and a second moving part. The first moving part passes through the water outlet. The second moving part is provided at one end of the first moving part and is located in the water outlet cavity. The sealing member is provided at the other opposite end of the first moving part and is located in the water storage cavity. The elastic member is provided between the second moving part and the first mounting base.

[0022] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the elastic element is set between the second moving part and the first mounting base. When the water box assembly is inserted into the slot, the spray part pushes the second moving part, and the force is transmitted to the first moving part through the integrated structure and compresses the elastic element. At this time, the sealing element moves away from the water outlet synchronously with the first moving part, and the water outlet gap is stably opened. When the water box is removed, the rebound force of the elastic element pushes the second moving part, and the sealing element is quickly reset through the first moving part, ensuring that the water outlet gap is closed in time.

[0023] In some embodiments of this application, the first mounting base has an opening on the side facing the spray section, the second moving part protrudes from the opening, the second moving part has a water outlet hole, the water outlet hole communicates with the water flow cavity, when the water outlet part is connected to the spray section, the second moving part contacts the spray section, and the water in the water flow cavity flows to the spray section through the water outlet hole.

[0024] Another technical solution described above has the following advantages or beneficial effects: When the water box assembly is installed in the slot, the spray section acts directly on the exposed second moving part through the opening, thereby pushing the entire moving part towards the water storage chamber. This direct contact method reduces intermediate links in force transmission, avoids force loss or delay that may occur with traditional indirect transmission, ensures that the elastic element can accurately respond to the installation action and contract, and allows the water outlet gap to open in a timely manner. At the same time, the edge of the opening can axially limit the second moving part, restricting its excessive displacement towards the spray section, preventing the moving part from deforming due to excessive force, and improving structural safety.

[0025] In some embodiments of this application, the spray section includes an atomizing plate, the slot has a spray nozzle on the side wall facing the drawer cavity, and the atomizing plate is provided corresponding to the spray nozzle; the spray section also includes a water guide, which is configured to guide water flowing out of the water outlet to the atomizing plate.

[0026] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the spray nozzle faces directly into the drawer cavity, and the humidifying mist generated by the atomizing plate can directly enter the drawer cavity through the spray nozzle, reducing the loss of mist during the transmission process.

[0027] The water guide can concentrate and guide the water flowing out from the water outlet (such as the circumferential water outlet of the second moving part) to the surface of the atomizing plate, ensuring that the atomizing plate is always in a wet state.

[0028] In addition, the water flowing out of the outlet may have a certain impact force due to water pressure. The water guide can weaken the kinetic energy of the water through its own structure (such as stepped guide or buffer chamber), so that the water flows to the atomizing plate in a stable state, reducing the vibration or noise of the atomizing plate caused by impact, improving the stability of the atomization process, and thus ensuring the uniformity of mist output.

[0029] In some embodiments of this application, the wall of the slot is provided with an installation groove, the spraying part is disposed in the installation groove, and the wall of the installation groove is provided with the spraying nozzle.

[0030] Another technical solution described above has the following advantages or beneficial effects: An installation groove is provided on the wall of the slot, and the spray unit is placed within it, forming a dedicated space for the spray unit. The circumferential limiting effect of the groove wall effectively constrains the displacement or vibration of the spray unit during the pulling out of the refrigerated drawer. The depth design of the installation groove allows the spray unit to be fully embedded within the slot, reducing direct contact between the food (especially larger items) inside the drawer and the spray unit.

[0031] In some embodiments of this application, the water box body and the drawer sidewall where the water box body is located are made of transparent material.

[0032] Another technical solution mentioned above has the following advantages or beneficial effects: the transparent material gives users the ability to intuitively observe the water level inside the water box, and they can grasp the timing of water replenishment without disassembling the water box or completely pulling out the refrigeration drawer.

[0033] The transparent material allows users to clearly see scale, mold, and other stains on the inner wall and slots of the water tank, enabling them to identify cleaning needs without disassembly. The light transmittance of the transparent material also helps users accurately install and remove the water tank.

[0034] In some embodiments of this application, the slot is provided on one or more of the front side wall, left side wall, and right side wall of the food storage drawer.

[0035] Another technical solution mentioned above has the following advantages or beneficial effects: regardless of whether the water tank assembly is set on a single side wall or multiple side walls, there is no need to adjust the drawer angle during installation and removal, and the vertical insertion and removal action is suitable for various user operation capabilities; the integrated design of the slot and side wall does not occupy the internal storage space of the drawer, maximizing the food storage volume; different side wall setting schemes can be flexibly selected according to the overall layout of the refrigerator (such as the lateral operation space when it is installed in a built-in manner), enhancing the adaptability of the product to the home environment. Through the diversification of side wall selection and the collaborative design of multiple water tanks, this utility model improves the convenience of operation while further optimizing the humidification efficiency and preservation accuracy, meeting the personalized usage needs of different users.

[0036] In some embodiments of this application, a refrigerator is provided, wherein an inner liner forms a refrigerator compartment; a fresh-keeping drawer is pulled out and disposed in the refrigerator compartment, the fresh-keeping drawer forming a drawer cavity; a water box assembly is detachably disposed on the side wall of the fresh-keeping drawer by means of vertical insertion and connection, the water box assembly being configured to provide humidifying mist to the drawer cavity; wherein, a spray section is provided on the side wall of the fresh-keeping drawer, the water box assembly includes a water outlet section, the water outlet section being configured to guide water in the water box assembly to the spray section, the spray section being configured to provide humidifying mist to the drawer cavity.

[0037] The above technical solution has the following advantages or beneficial effects: This solution uses a "top and bottom plug-in" method to detachably install the water tank assembly onto the side wall of the food storage drawer. During installation, the user can directly insert the water tank assembly vertically downwards along the plug-in structure on the side wall, without the need for precise alignment of complex clips. During disassembly, simply pull upwards to detach the water tank assembly from the plug-in structure; the operation conforms to the natural force application habits of the human body. This design significantly reduces the difficulty of installing and removing the water tank assembly, reduces user operation time, and improves the convenience of daily maintenance (such as adding water and cleaning).

[0038] In existing technologies, the water tank and atomizing plate are integrated into one unit, which can easily lead to water circuit interruption or poor contact of the atomizing plate when disassembled or moved. This solution optimizes the humidification chain through a separate design of the "water outlet section and spray section". The spray section is fixed to the side wall of the refrigerator drawer to ensure stable atomization position; the water outlet section of the water tank assembly automatically aligns with the spray section during insertion, realizing water circuit continuity and avoiding the problem of unstable water supply caused by installation deviation in traditional integrated designs.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0070] In some embodiments of this application, a refrigerator is provided, as shown in the reference... Figure 1 The refrigerator includes a cabinet 10. The interior of the cabinet 10 forms a storage space.

[0071] The interior of the cabinet 10 is equipped with multiple partitions, which divide the storage space into multiple storage compartments. These multiple storage compartments are arranged vertically or horizontally. The storage space serves as a freezer, refrigerator, and variable temperature compartment, etc., to meet different storage needs such as freezing, refrigeration, and variable temperature storage according to different types of food.

[0072] The cabinet 10 has an inner liner 20, and storage compartments are formed within the inner liner 20. It can be understood that the cabinet 10 has multiple inner liners 20, and each inner liner 20 can form one or more storage compartments.

[0073] The refrigerator also includes a door 30. The door 30 is connected to the cabinet 10 and is configured to close or open the storage space. For example, the door 30 is rotatably connected to the cabinet 10 by a hinge, and the door 30 can rotate around the hinge axis to open and close the door 30, thereby opening or closing the storage space.

[0074] There are multiple doors 30, and each door 30 corresponds to a storage room.

[0075] The refrigerator also includes a refrigeration unit. This unit provides cooling to the interior of the refrigerator to maintain a low-temperature environment in each storage compartment. The refrigeration unit includes a compressor, condenser, evaporator, and throttling devices. The specific structure and connections of the refrigeration unit can be found in relevant technical documents on refrigeration components, and will not be elaborated upon here.

[0076] In some embodiments of this application, reference is made to Figure 2 , Figure 2 Only a structural schematic diagram of the inner liner 20 and some components disposed therein is shown. The refrigerator includes an inner liner 20, which forms a refrigerator compartment 50.

[0077] The refrigerator also includes a crisper drawer 100. The crisper drawer 100 is installed in the refrigerator compartment 50 by pulling it out from the front and back to facilitate opening and closing. The side of the crisper drawer 100 that is pulled out and opened is defined as the front side of the crisper drawer 100. Figure 4 The diagram shown is a structural schematic of a food storage drawer 100.

[0078] The top of the food storage drawer 100 is open to facilitate the retrieval or placement of items. The top of the food storage drawer 100 is equipped with a cover, which closes the top opening of the food storage drawer 100 when the food storage drawer 100 is closed.

[0079] For example, refer to Figure 2 and Figure 3 The refrigerator compartment 50 is equipped with a shelf 40, and the fresh food drawer 100 is located below the shelf 40. The shelf 40 also serves as the top cover of the fresh food drawer 100. For example, the refrigerator compartment 50 is specially equipped with a cover structure for closing the open top of the fresh food drawer 100.

[0080] The food storage drawer 100 has a drawer cavity 110 inside, and the top of the drawer cavity 110 is open. The side wall of the food storage drawer 100 is provided with a slot 120, and the top of the slot 120 is open.

[0081] The refrigerator also includes a water tank assembly 200. The water tank assembly 200 is detachably disposed within the slot 120, and is inserted downward into the slot 120 or removed upward from the slot 120 through a top side opening. The water tank assembly 200 is configured to provide humidifying mist into the drawer cavity 110. Figure 6 This is a structural schematic diagram of the water box assembly 200. Figure 5 A cross-sectional view of the water tank assembly 200 placed within the slot 120.

[0082] The refrigerator of this application has a slot 120 with an open top on the side wall of the crisper drawer 100, which allows the water box assembly 200 to be directly inserted vertically downward or taken out upward through the open slot. The structure is adapted to the natural operating trajectory of the human body, and the user does not need to deliberately adjust the angle of force, making it easy to operate.

[0083] Traditional top-and-bottom mounted water tanks rely on friction or snap-fit ​​for fixation, which can easily loosen due to vibration during drawer operation, and may even cause the atomizing plate 310 to detach from the power supply interface. In this solution, the slot 120 provides left, right and bottom limits for the water tank assembly 200, and together with the gravity self-positioning effect of vertical installation, the water tank assembly 200 remains stable during drawer opening and closing.

[0084] Water tanks are prone to limescale or mold growth after prolonged use, requiring regular cleaning. Existing structures are difficult to disassemble, leading users to often neglect cleaning and resulting in decreased preservation effectiveness. The detachable design of this application allows the water tank component 200 to be completely removed from the refrigeration space, facilitating thorough cleaning or disinfection. Furthermore, the open design of the slot 120 allows for direct observation of the internal cleanliness, reducing hard-to-reach areas and indirectly improving the cleanliness of the food preservation environment, ensuring the stability of the atomized humidification effect.

[0085] Compared to the complex snap-fit ​​structure of traditional water boxes, the slot 120 design requires no additional connectors; the limiting function is achieved through the integral molding of the drawer sidewall. During assembly, the water box component 200 does not need to be precisely aligned with the snap-fit ​​positions; it only needs to be vertically inserted along the slot 120 to complete the positioning, shortening assembly time on the production line. At the same time, this structure reduces mold complexity and injection molding difficulty, making it suitable for mass production.

[0086] This structure offers greater adaptability to the shape of the water tank component 200, accommodating water tank designs of different volumes or shapes. Interchangeability is achieved simply by matching the 120-sized slot. When users need to replace the water tank with a larger capacity one or upgrade the atomizing component, there's no need to modify the main drawer structure; only the water tank component 200 needs to be replaced. This facilitates future functional iterations and enhances the product's market competitiveness.

[0087] In some embodiments of this application, the slot 120 is provided on one or more of the front side wall, left side wall and right side wall of the food storage drawer 100.

[0088] For example, a water box assembly 200 is provided inside the food storage drawer 100, and the water box assembly 200 is provided on one of the front side wall, left side wall and right side wall of the food storage drawer 100.

[0089] Figure 3 In the structure shown, a slot 120 is provided on the front side wall of the food storage drawer 100, and a water box assembly 200 is provided on the front side wall of the food storage drawer 100. Figures 7 to 10 This is a schematic diagram of the structure when the water box assembly 200 is installed on the front side wall of the food storage drawer 100.

[0090] When the slot 120 and water box assembly 200 are installed on the front wall of the refrigerated drawer 100, their structure is deeply adapted to user operating habits. The front wall serves as the visual focus and main operating interface when the drawer is pulled out. Users can observe the water box status without fully pulling the drawer out. When adding water or removing the drawer, users only need to pull it vertically upwards along the slot 120 on the front wall, with minimal movement and unobstructed view. This setup is particularly suitable for scenarios requiring frequent daily water replenishment, such as when storing leafy vegetables or other high-humidity foods. It reduces cold loss caused by fully pulling out the drawer, shortens the operation path, and improves user convenience. In addition, the water box on the front wall can atomize directly towards the inside of the drawer cavity 110, with a short mist diffusion path, which can quickly increase the humidity in the front area of ​​the drawer, meeting the preservation needs of frequently accessed foods in the front.

[0091] Figure 11 In the structure shown, a slot 120 is provided on one of the left or right side walls of the food storage drawer 100, and a water box assembly 200 is provided on the left or right side wall of the food storage drawer 100. Figures 11 to 14 This is a schematic diagram of the structure when the water box assembly 200 is installed on the right side wall of the food storage drawer 100.

[0092] When the water tray assembly 200 is placed on the left or right side wall, it makes full use of the unused space on the side of the drawer and avoids interference with the food storage area in the middle of the drawer. For foods that require long-term preservation and do not require frequent watering (such as meat and fruit), the side placement reduces direct contact between the water tray and the food, lowering the risk of accidental displacement. Meanwhile, the vertical installation and removal of the side slot 120 still maintains ease of operation. Furthermore, the side installation keeps the water tray away from the front handle area of ​​the drawer, preventing users from bumping their hands against the water tray when pulling out the drawer.

[0093] For example, the food storage drawer 100 is provided with multiple water box components 200, which are distributed on the front side wall, left side wall and right side wall of the food storage drawer 100.

[0094] When multiple side walls of the food storage drawer 100, including the front, left, and right side walls, are equipped with slots 120 and water box assemblies 200 are installed, a multi-dimensional synergistic humidification effect can be achieved. For example, the water box on the front side wall is responsible for quickly replenishing the humidity at the front of the drawer, while the water boxes on the left and right side walls diffuse mist into the middle and rear areas, making the humidity distribution within the drawer cavity 110 more uniform and solving the problem of localized over-dryness or over-humidity caused by the limited atomization range of traditional single water boxes.

[0095] The distributed setup also allows for flexible matching of humidification needs for drawers of different capacities: for the large-capacity fresh food drawer 100, the simultaneous operation of multiple water boxes can increase the mist output per unit time, ensuring that the drawer cavity 110 reaches the set humidity in a short time; for partitioned storage scenarios (such as vegetables in the front and dry goods in the back), the atomization frequency of different side wall water boxes can be individually controlled to achieve precise local humidity control in the drawer.

[0096] In addition, the multi-water-box design has a redundancy backup function. When a single water box needs cleaning or malfunctions, the remaining water boxes can still maintain the basic humidification effect, preventing food from spoiling due to humidification interruption and improving the reliability of equipment operation.

[0097] In the above embodiments, regardless of whether the water box assembly 200 is located on a single side wall or multiple side walls, it retains the core advantages of the top-opening slot 120: no adjustment of the drawer angle is required during installation or removal, and the vertical insertion and removal action is suitable for various user operation capabilities; the integrated design of the slot 120 and the side wall does not occupy the internal storage space of the drawer, maximizing the food storage capacity; different side wall settings can be flexibly selected according to the overall layout of the refrigerator (such as the lateral operating space when it is installed in a built-in manner), enhancing the adaptability of the product to the home environment. Through the diversification of side wall selection and the collaborative design of multiple water boxes, this utility model improves the ease of operation while further optimizing the humidification efficiency and preservation accuracy, meeting the personalized usage needs of different users.

[0098] In some embodiments of this application, the water box body 210 and the drawer sidewall where the water box body 210 is located are made of transparent material.

[0099] The transparent material allows users to visually observe the water level inside the water tank, enabling them to determine when to rehydrate without disassembling the tank or fully pulling out the refrigerator drawer. For example:

[0100] When the water box assembly 200 is installed on the front side wall, the user can directly observe the transparent side wall and the water box body 210 through the glass of the refrigerator door 30 to determine whether the water level is sufficient, thus avoiding the loss of cold air caused by frequently pulling out and pulling the drawer to check the water level.

[0101] For the water tank assembly 200 located on the left or right side wall, the transparent side wall can clearly show the water level line inside the water tank when the drawer is half open. This is especially suitable for scenarios with limited lateral operating space, such as built-in refrigerators, reducing the amount of operation required to fully pull out the drawer.

[0102] This design solves the problem that traditional opaque structures require disassembling the water tank to check the water level, reducing the frequency of operation and improving user efficiency.

[0103] The transparent material allows users to clearly see scale, mold, and other stains on the inner wall of the water tank and inside the slot 120, enabling them to identify cleaning needs without disassembly. For example:

[0104] If limescale builds up at the bottom of the water tank after prolonged use, the transparent body will make it clearly visible, reminding the user to remove and clean it in time.

[0105] If impurities accumulate in the gap between slot 120 and the water tank, the transparent sidewall can directly show the location of the contaminants, making it easy to clean in a targeted manner and avoiding the risk of bacterial growth caused by the concealment of stains in traditional opaque structures.

[0106] This visualization feature, combined with the convenient installation and removal design of the water box component 200, forms a closed-loop experience of "observation-cleaning," ensuring the hygiene of the humidification system and indirectly improving the quality of food preservation.

[0107] The light transmittance of transparent materials helps users accurately load and unload water tanks. For example:

[0108] When installing the water box, users can observe the alignment of the water box and slot 120 through the transparent side wall to avoid misalignment caused by visual obstruction and ensure that the atomizing plate 310 and the power supply interface are accurately connected.

[0109] For elderly users or those with poor eyesight, the transparent material allows light to refract and clearly show the outline of slot 120, reducing the probability of operational errors.

[0110] In addition, the transparent design and different side wall settings create synergistic advantages: the transparent front side wall enhances the convenience of daily observation, while the transparent sides ensure water level monitoring needs are met even when the drawer is open, adapting to diverse user habits.

[0111] In some embodiments of this application, reference is made to Figure 6 The water tank assembly 200 includes a water tank body 210, within which a water storage cavity 213 is formed. For example, the water tank body 210 has a cuboid structure, and the slot 120 corresponds to a cuboid slot structure. A cover plate 211 is provided on the top of the water tank body 210, which is used to open or close the water tank. Opening the cover plate 211 allows water to be injected into the water storage cavity 213.

[0112] The water tank body 210 has a rectangular structure and forms a water storage cavity 213. It is designed to fit a rectangular slot 120, allowing for precise matching between the water tank and the slot 120, reducing installation gaps, preventing the water tank from wobbling during drawer operation, and improving structural stability. The rectangular structure efficiently utilizes the drawer side wall space, maximizing water storage capacity within a limited volume and reducing the frequency of water refills.

[0113] The cover 211 on top of the water tank body 210 provides a convenient path for users to add water. When the cover 211 is opened, water can be directly added to the water storage chamber 213 without disassembling the water tank assembly 200, simplifying the water replenishment process. When the cover 211 is closed, it effectively prevents condensate from dripping into the water storage chamber 213 in the refrigerator compartment 50, thus preventing abnormal water levels. It also prevents the water in the water storage chamber 213 from evaporating too quickly due to airflow disturbances inside the refrigerator, maintaining the stability of the water level in the water storage chamber 213. In addition, the sealed fit between the cover 211 and the water tank body 210 reduces the exchange of odors and prevents the water quality in the water storage chamber 213 from being affected by the odors of food in the drawer, ensuring the cleanliness of the humidifying mist.

[0114] Reference Figure 5 and Figure 6 The water box assembly 200 further includes a water outlet 220. The water box body 210 is provided with an installation port, and the water outlet 220 is fixedly installed at the installation port.

[0115] Reference Figure 5 and Figure 9 The slot 120 is provided with a spray section 300, which is configured to provide humidifying mist into the drawer cavity 110.

[0116] Reference Figure 5 The water outlet 220 is configured to guide water in the water storage chamber 213 to the spray section 300 when the water box body 210 is installed in the slot 120.

[0117] The water outlet 220 is also configured to close when the water box body 210 is removed from the slot 120 to prevent water from flowing out of the water storage chamber 213.

[0118] The water outlet 220 and the spray unit 300 work synergistically. Specifically, the water outlet 220 is fixed to the mounting port of the water box body 210 and precisely matches the spray unit 300 on the slot 120, achieving efficient linkage of "water storage-water delivery-atomization". When the water box assembly 200 is installed into the slot 120, the water outlet 220 and the spray unit 300 automatically connect, stably guiding the water in the water storage chamber 213 to the spray unit 300 (such as the atomizing plate 310), ensuring a continuous water supply to the spray unit 300 and guaranteeing a stable output of humidifying mist. This directional guidance design avoids the problem of unstable water supply caused by the traditional water box relying on gravity dripping, keeping the humidity in the drawer cavity 110 uniform and improving the food preservation effect.

[0119] The spray unit 300 is mounted on the slot 120, its position adapted to the spatial distribution of the drawer cavity 110. For example, when the water tank assembly 200 is installed on the front side wall, the spray unit 300 can directly release mist into the front food area; when installed on the side, the mist can diffuse along the side wall to the center of the drawer for targeted humidification. Compared to the traditional design where the water tank atomizing plate 310 is directly mounted on the water tank, this solution integrates the spray unit 300 with the slot 120, reducing the structural complexity of the water tank body 210, lowering the risk of contact with the atomizing component during water tank installation and removal, and extending the service life of the spray unit 300.

[0120] The water outlet 220 features an adaptive function of "open during installation and closed during removal," a core design feature that solves the leakage problem during disassembly of traditional water tanks. When the water tank assembly 200 is removed from the slot 120, the water outlet 220 automatically closes, effectively preventing residual water in the water storage chamber 213 from flowing out and avoiding water accumulation in the drawer or refrigerator compartment 50, thus reducing the user's cleaning burden. For example, when the user temporarily removes the water tank to check the water level or for cleaning, even if there is water in the water storage chamber 213, there is no need to empty it beforehand; the operation can be performed directly, improving ease of use.

[0121] This sealing function is particularly suitable for the vertical installation and removal of the water box assembly 200: when the user removes the water box upwards, the water outlet 220 is quickly sealed due to the resistance of the spray section 300. Combined with the cuboid structure of the water box body 210, it can form all-round leak-proof protection to prevent water from flowing along the outer wall of the water box.

[0122] The combined design of the above structures forms a complete closed loop of use: "convenient water filling - stable water delivery - precise humidification - safe leak prevention". The compatibility between the cuboid water box and the slot 120 ensures a stable installation, the cover 211 simplifies daily water replenishment operations, the linkage between the water outlet 220 and the spray section 300 ensures humidification efficiency, and the sealing function of the water outlet 220 completely solves the problem of leakage during disassembly.

[0123] Compared to existing technologies, this solution eliminates the need for additional valve operation or water emptying during water box installation and removal. All water delivery and leak prevention actions are automatically completed during water box installation / removal, significantly reducing the user's operational threshold. Furthermore, the modular design of each component (such as the independent configuration of the water outlet 220 and the spray unit 300) facilitates future maintenance and replacement. If the spray unit 300 or the water outlet 220 malfunctions, the corresponding component can be replaced individually, reducing maintenance costs.

[0124] In some embodiments of this application, reference is made to Figure 5 The water outlet 220 includes a first mounting base 221, which is fixedly mounted at the mounting opening by a snap-fit ​​mechanism. A water-carrying cavity 225 is formed within the first mounting base 221, extending through the first mounting base 221 and open at both ends. A water outlet (not shown) is provided on the first mounting base 221, located at one end of the water-carrying cavity 225, communicating with the water outlet and the water storage cavity 213. The other opposite end of the water-carrying cavity 225 communicates with the spray section 300, thus allowing water from the water-carrying cavity 225 to be supplied to the spray section 300.

[0125] The water-carrying cavity 225 within the first mounting base 221 provides a directional channel for water flow. Its open ends connect to the water storage cavity 213 (via the water outlet) and the spray section 300, forming a complete water circuit: "water storage cavity 213 - water outlet - water-carrying cavity 225 - spray section 300". This closed-loop design reduces evaporation and contamination during water transmission, while also preventing corrosion risks caused by direct contact between the water flow and other components of the water tank, ensuring the cleanliness of the water supply. Furthermore, the tubular structure of the water-carrying cavity 225 constrains the water flow direction, concentrating the water flow towards the spray section 300 and improving water supply efficiency.

[0126] The water outlet 220 also includes a moving member 222, which passes through the water inlet and forms a water outlet gap 226 between the moving member 222 and the water inlet. For example, the moving member 222 is a columnar structure, which passes through the water inlet cavity 225 and one end of the moving member 222 passes through the water inlet.

[0127] The water outlet 220 also includes an elastic element 223, which is disposed within the water flow cavity 225. The elastic element 223 is configured to apply a force to the moving element 222, causing the moving element 222 to move away from the water storage cavity 213. For example, the elastic element 223 is a spring, which is sleeved on the outer periphery of the moving element 222. One end of the spring abuts against the first mounting base 221, and the other end of the spring abuts against the end of the moving element 222 away from the water storage cavity 213. Under the elastic force of the spring, the moving element 222 moves away from the water storage cavity 213.

[0128] The water outlet 220 also includes a sealing member 224, which is connected to the moving member 222. The sealing member 224 is configured to block the water outlet gap 226 when the moving member 222 moves away from the water storage chamber 213. The sealing member 224 is also configured to open the water outlet gap 226 when the moving member 222 moves towards the water storage chamber 213.

[0129] In other words, the sealing component 224 is a plug structure. In Figure 5 In the indicated state, the water outlet 220 is connected to the spray section 300. Under the pressure of the spray section 300, the elastic member 223 contracts, and the moving member 222 moves towards the water storage chamber 213, causing the sealing member 224 to move away from the water outlet gap 226. The water outlet gap 226 opens, and the water in the water storage chamber 213 flows into the water flow chamber 225 through the water outlet gap 226, and then flows from the water flow chamber 225 to the spray section 300.

[0130] When the water box assembly 200 is removed from the slot 120, the force exerted by the spray section 300 on the moving part 222 disappears, the elastic part 223 rebounds, and the elastic part 223 drives the moving part 222 to move away from the water storage chamber 213, which in turn drives the sealing part 224 to approach the water outlet gap 226. The sealing part 224 blocks the water outlet gap 226, and at this time the water in the water storage chamber 213 cannot flow out.

[0131] The moving component 222, with its columnar structure, passes through the water-carrying cavity 225. The water outlet gap 226 between the columnar structure and the water outlet is the key channel for water to enter the water-carrying cavity 225. The fitting precision between the columnar structure and the water outlet can be precisely controlled through dimensional design to ensure the consistency of the water outlet gap 226, thereby stabilizing the water flow rate. This avoids water waste caused by an excessively large gap and insufficient water supply caused by an excessively small gap.

[0132] When the water box assembly 200 is inserted into the slot 120, the end of the moving part 222 away from the water storage chamber 213 contacts the spray section 300 and is subjected to its pressure, moving towards the water storage chamber 213. At this time, the water outlet gap 226 opens due to the displacement of the moving part 222, and the water in the water storage chamber 213 can flow smoothly into the water inlet chamber 225 through this gap. When the water box assembly 200 is removed, the moving part 222 returns to its original position under the action of the elastic element 223, and the water outlet gap 226 shrinks accordingly. This gap design, which automatically changes with the installation state of the water box, realizes "on-demand supply" of water flow, eliminating the need for manual valve operation by the user and simplifying the usage process.

[0133] An elastic element 223 (such as a spring) is sleeved on the outer periphery of the moving element 222, with its two ends abutting against the first mounting base 221 and the moving element 222 respectively. The elastic force provides a continuous reset driving force to the moving element 222. When the water tank assembly 200 is installed in the slot 120, the pressure of the spray section 300 on the moving element 222 overcomes the elastic force of the elastic element 223, causing the moving element 222 to move towards the water storage chamber 213. At this time, the elastic element 223 is in a contracted state and stores elastic potential energy. When the water tank assembly 200 is removed, the pressure of the spray section 300 disappears, and the elastic element 223 releases its potential energy, driving the moving element 222 to move away from the water storage chamber 213, thus achieving automatic reset.

[0134] The core advantage of this design lies in its "automatic response without power": it eliminates the need for motors or other driving components, allowing the movement of component 222 to switch states solely through mechanical structures, thus reducing structural complexity and the risk of failure. Simultaneously, the elastic force of component 223 can be precisely controlled through selection and design, ensuring smooth movement of component 222 upon contact with the spray section 300 (avoiding excessive resistance that could lead to installation difficulties), and rapid resetting upon removal (ensuring timely sealing).

[0135] The sealing component 224 is connected to the moving component 222 and controls the opening and closing of the water outlet gap 226 as the moving component 222 moves. It is the core component for the leak-proof function of the water outlet section 220. When the water box assembly 200 is removed, the moving component 222 moves away from the water storage cavity 213 under the action of the elastic component 223. The sealing component 224 moves with it and fits tightly against the edge of the water outlet, completely sealing the water outlet gap 226. At this time, even if there is water in the water storage cavity 213, it cannot flow out through the water outlet, fundamentally solving the leakage problem when the traditional water box is disassembled.

[0136] In some embodiments of this application, reference is made to Figure 5 The moving part 222 includes a first moving part 2221 and a second moving part 2222, which are integral structures.

[0137] The first moving part 2221 has a rod-shaped structure, and the second moving part 2222 has a disc-shaped structure. The first moving part 2221 passes through the water inlet, and the second moving part 2222 is fixedly installed at one end of the first moving part 2221, while the sealing member 224 is fixedly installed at the other opposite end of the first moving part 2221. The second moving part 2222 is located in the water inlet cavity 225, the sealing member 224 is located in the water storage cavity 213, and the elastic member 223 is disposed between the second moving part 2222 and the first mounting base 221.

[0138] The design of the first moving part 2221 passing through the water outlet isolates the sealing member 224 in the water storage chamber 213 from the second moving part 2222 in the water outlet chamber 225 in different spaces, preventing them from interfering with other components during movement. For example, water or impurities in the water storage chamber 213 will not directly contact the second moving part 2222 and the elastic member 223, reducing the impact on the elastic stability of the elastic member 223 and extending the service life of the components.

[0139] The second moving part 2222 has a disc-shaped structure and is located within the water-flow cavity 225. Its cooperation with the elastic element 223 forms an efficient force transmission mechanism. The large area of ​​the disc-shaped structure allows the force of the elastic element 223 (such as a spring) to be evenly distributed on the surface of the second moving part 2222. At the same time, the disc-shaped structure and the inner wall of the water-flow cavity 225 can form a radial limit, restricting the lateral displacement of the moving part 222 during movement, ensuring that the first moving part 2221 always moves along the axial direction of the water outlet, ensuring the alignment accuracy of the sealing element 224 with the water outlet, and improving the sealing reliability.

[0140] The elastic element 223 is disposed between the second moving part 2222 and the first mounting base 221. When the water box assembly 200 is inserted into the slot 120, the spray part 300 pushes the second moving part 2222, and transmits the force to the first moving part 2221 through the integrated structure and compresses the elastic element 223. At this time, the sealing element 224 moves away from the water outlet synchronously with the first moving part 2221, and the water outlet gap 226 is stably opened. When the water box is removed, the rebound force of the elastic element 223 pushes the second moving part 2222, and the sealing element 224 is quickly reset through the first moving part 2221, ensuring that the water outlet gap 226 is closed in time.

[0141] In some embodiments of this application, reference is made to Figure 5 and Figure 6 The first mounting base 221 has an opening on the side facing the spray section 300, and the second moving part 2222 protrudes from the opening. The second moving part 2222 has a plurality of circumferentially distributed water outlet holes 2223. The water outlet holes 2223 communicate with the water flow chamber 225. When the water outlet section 220 is connected to the spray section 300, the second moving part 2222 contacts the spray section 300, and the water in the water flow chamber 225 flows to the spray section 300 through the water outlet holes 2223.

[0142] The first mounting base 221 has an opening on the side facing the spray section 300, and the second moving part 2222 protrudes from this opening. This design provides a structural basis for direct contact between the moving part 222 and the spray section 300. The size and shape of the opening are adapted to the disc-shaped structure of the second moving part 2222, ensuring that the second moving part 2222 can always extend from the opening and form a stable contact with the spray section 300 during reciprocating motion (as the water box is installed / removed), avoiding interruption of pressure transmission due to obstruction by the mounting base 422.

[0143] Specifically, when the water box assembly 200 is inserted into the slot 120, the spray section 300 acts directly on the exposed second moving part 2222 through the opening, causing the pressure to be evenly distributed along the disc-shaped structure, thereby pushing the moving part 222 as a whole to move towards the water storage chamber 213. This direct contact method reduces intermediate links in force transmission, avoids force loss or delay that may occur in traditional indirect transmission, and ensures that the elastic element 223 can accurately respond to the installation action and contract, so that the water outlet gap 226 opens in time. At the same time, the edge of the opening can axially limit the second moving part 2222, restricting its excessive displacement towards the spray section 300, preventing the moving part 222 from deforming due to excessive force, and improving structural safety.

[0144] Multiple water outlets 2223 on the second moving part 2222 are distributed circumferentially and communicate with the water flow chamber 225. This structure is a key design for optimizing the water flow to the spray part 300. The circumferential distribution allows water in the water flow chamber 225 to flow out from multiple directions simultaneously, forming a uniform water flow distribution and avoiding the problems of local water concentration or excessive water flow impact that may be caused by a single water outlet 2223. For example, when water flows through the water passage 225 to the second moving part 2222, the circumferential water outlets 2223 can disperse the water flow into multiple streams, which flow smoothly towards the spray part 300 (e.g., mist). The total flow area of ​​the multiple water outlets 2223 can be precisely matched to the water demand of the spray part 300 through the design of the number and diameter of the outlets, ensuring sufficient water supply (avoiding dry burning of the atomizing plate 310) and preventing water accumulation due to excess water. At the same time, the circumferential distribution ensures that when the second moving part 2222 comes into contact with the spray part 300, even if there is a slight angular deviation, some of the water outlets 2223 can remain unobstructed, ensuring that the basic water supply is not affected and improving the structural tolerance.

[0145] In some embodiments of this application, reference is made to Figure 5 The spray unit 300 includes an atomizing plate 310, and the slot has a spray nozzle 140 on the side wall facing the drawer cavity 110, with the atomizing plate 310 corresponding to the spray nozzle 140.

[0146] The spray section 300 also includes a water guide 320, which is configured to guide water flowing out of the water outlet 220 to the atomizing plate 310.

[0147] The spray nozzle 140 faces directly into the drawer cavity 110, allowing the humidifying mist generated by the atomizing plate 310 to enter the drawer cavity 110 directly through the spray nozzle 140, reducing mist loss during transmission. Compared to a non-directional spray design, this structure enables the mist to quickly diffuse to the food storage area, shortening the humidity increase time. It is especially suitable for humidity-sensitive leafy vegetables, preventing moisture loss due to delayed humidification.

[0148] The spray nozzle 140 directs the mist release, reducing the probability of the mist directly contacting other areas of the water tank body 210 or the drawer sidewalls, thus reducing the accumulation of condensate in non-target areas, thereby reducing the risk of mold growth and ensuring the cleanliness of the preservation environment. Simultaneously, the correspondence between the atomizing plate 310 and the spray nozzle 140 can be further optimized through structural design (such as sealing gaskets) to prevent mist from overflowing from gaps into the water tank or slot 120, avoiding any impact on the water quality in the water storage chamber 213 or the structure of the slot 120.

[0149] By combining the transparent material design of the water tank body 210 and the drawer side wall, users can observe the working status of the atomizing plate 310 (such as whether it produces mist normally) through the spray nozzle 140, which makes it easier to detect malfunctions or blockages of the atomizing plate 310 in a timely manner and improve the timeliness of maintenance.

[0150] The water guide 320 can concentrate and guide the water flowing out from the water outlet 220 (such as the circumferential water outlet 2223 of the second moving part 2222) to the surface of the atomizing plate 310, ensuring that the atomizing plate 310 is always in a moist state. Compared with the method of water dripping directly, the water guide 320 can avoid the atomizing plate 310 from local dry burning due to uneven water distribution, thus extending the service life of the atomizing plate 310.

[0151] The water flowing out of the outlet 220 may have a certain impact force due to water pressure. The water guide 320 can weaken the kinetic energy of the water through its own structure (such as stepped guide or buffer chamber), so that the water flows to the atomizing plate 310 in a stable state, reducing the vibration or noise of the atomizing plate 310 caused by impact, improving the stability of the atomization process, and thus ensuring the uniformity of mist output.

[0152] The closed or semi-closed structure of the water guide 320 can confine the water flow within a specific range, preventing water from overflowing into the water box body 210 or slot 120 and causing water accumulation. At the same time, the precise guidance of the water guide 320 can reduce water waste, allowing more water to be used for atomization humidification and improving water resource utilization.

[0153] In some embodiments of this application, reference is made to Figure 9 and Figure 10 The wall of the slot 120 is provided with a mounting groove 130, the spray part 300 is disposed in the mounting groove 130, and the wall of the mounting groove 130 is provided with a spray nozzle 140.

[0154] A mounting groove 130 is provided on the wall of the slot 120, and the spray unit 300 is placed therein, forming a dedicated space for the spray unit 300. The outline of the mounting groove 130 is precisely matched with the spray unit 300 (such as the combination of the atomizing plate 310 and the water guide 320). Through the circumferential limiting of the groove wall, the displacement or vibration of the spray unit 300 during the pulling and pulling of the food storage drawer 100 can be effectively restrained. Compared with the design of directly fixing the spray unit 300 to the wall of the slot 120, the mounting groove 130 can avoid the spray unit 300 from loosening due to the inertial force generated by the frequent opening and closing of the drawer, ensuring its docking accuracy with the water outlet 220 (such as the second moving part 2222), and maintaining a stable water supply and atomization effect.

[0155] The depth design of the mounting slot 130 allows the spray unit 300 to be fully embedded in the slot 120, reducing direct contact between food items (especially larger items) in the drawer and the spray unit 300. For example, when a user takes food out or puts it in, the edge of the mounting slot 130 can prevent the food from colliding with the atomizing plate 310 or the water guide 320, avoiding damage or displacement of components, extending the service life of the spray unit 300, and reducing the risk of interruption of mist output due to collision.

[0156] In some embodiments of this application, reference is made to Figure 6 The water tank body 210 is provided with a handle 212, for example, a handle 212 is provided on the side wall of the water tank body 210. (See reference...) Figure 4 The handle 212 protrudes from the side wall of the slot 120, making it easy for the user to operate the handle 212 to retrieve the water box.

[0157] In some embodiments of this application, the distance between the spray nozzle 140 and the bottom wall of the food preservation drawer 100 is D1, and the height of the food preservation drawer 100 is D, where D1 = 2 / 3D.

[0158] The diffusion of mist within the food storage drawer 100 is influenced by gravity and air convection, typically exhibiting the characteristic of "diffusion after release, followed by slow settling." Positioning the spray nozzle 140 at 2 / 3 of the drawer's height (upper middle area) ensures that the mist is in the core circulation space of the drawer from the initial release stage.

[0159] Compared to a setting closer to the top wall (D1 close to D), the mist released at this location has ample space to descend, gradually covering the entire drawer cavity 110 from top to bottom, preventing the mist from concentrating at the top and causing insufficient humidity in the bottom. Compared to a setting closer to the bottom wall (D1 close to 0), it reduces the obstruction of the mist by the lower food items, allowing the mist to diffuse upwards to the top area of ​​the drawer, making it especially suitable for storing layered food items (such as vegetables on the top and fruits on the bottom).

[0160] In some embodiments of this application, reference is made to Figure 5 The spray unit 300 also includes a second mounting base 330. The atomizing plate 310 is fixedly mounted on the second mounting base 330.

[0161] The second mounting base 330 secures the atomizing plate 310 using slots, screws, or interference fits, ensuring that the atomizing plate 310 is precisely aligned with the spray nozzle 140. Compared to designs that directly glue or screw the atomizing plate 310 to the wall of the slot 120, the second mounting base 330 can precisely control the flatness and perpendicularity of the atomizing plate 310 through mold precision, avoiding deviation in the mist spray direction caused by installation tilt, ensuring that the mist enters the drawer cavity 110 through the spray nozzle 140, and improving humidification uniformity.

[0162] The atomizing plate 310 generates high-frequency vibrations during operation. The second mounting base 330 can be made of elastic material (such as a silicone pad) or have a buffer structure to reduce the transmission of vibrations to the slot 120 or the drawer body. This not only reduces operating noise but also prevents the solder joints of the atomizing plate 310 from falling off or the wiring from becoming loose due to long-term vibration, thus extending the service life of the core components.

[0163] The second mounting bracket 330 can be made of insulating material (such as ABS plastic) to isolate the electrodes of the atomizing plate 310 from the metal slot 120 wall, preventing the risk of short circuit caused by condensation in the refrigerator and improving electrical safety, especially suitable for the high humidity environment in the refrigerator compartment 50.

[0164] The spray unit 300 also includes a third mounting base 340, and the water guide 320 is fixedly disposed in the mounting port of the third mounting base 340. The third mounting base 340 is fixed in the slot 120 by a plug-in and snap-fit ​​method. The second mounting base 330 is fixedly connected to the third mounting base 340.

[0165] The third mounting base 340 secures the water guide 320 via the mounting port and also serves as a bridge connecting the spray section 300 and the slot 120. The water guide 320 (such as an arc-shaped guide channel or a sponge absorbent) needs to form a continuous water path with the water outlet 220 (the second moving part 2222) and the atomizing plate 310. The mounting port of the third mounting base 340 can precisely constrain the shape and position of the water guide 320. For example, the contour of the mounting port matches the outer periphery of the water guide 320, ensuring that the water guide 320 does not shift when impacted by water flow or when the drawer vibrates, maintaining smooth water flow from the water outlet 220 to the atomizing plate 310, and preventing the atomizing plate 310 from burning out due to flow interruption.

[0166] The rigid connection between the second mounting base 330 and the third mounting base 340 ensures that the water outlet of the water guide 320 and the water intake of the atomizing plate 310 are tightly fitted, preventing water overflow caused by gaps between them. For example, the end of the water guide 320 is designed to match the surface of the atomizing plate 310. Through the precise docking of the two mounting bases 422, the water flow can evenly cover the atomization area of ​​the atomizing plate 310, improving water utilization.

[0167] The atomizing plate 310 and the water guide component 320 form an independent module via a mounting base, allowing for pre-assembly and testing before shipment, reducing assembly steps on the production line. When the spray unit 300 malfunctions, the user or maintenance personnel can replace the entire module without individually adjusting the positions of the atomizing plate 310 or the water guide component 320, reducing maintenance difficulty. For example, the transparent slot 120 wall provides a clear view of whether the module is installed correctly, preventing functional malfunctions caused by assembly deviations.

[0168] In some embodiments of this application, reference is made to Figure 2 The refrigerator includes an inner liner 20, which forms a refrigerator compartment 50.

[0169] The refrigerator also includes a crisper drawer 100. The crisper drawer 100 is installed in the refrigerator compartment 50 by pulling it out from the front and back to facilitate opening and closing. The side of the crisper drawer 100 that is pulled out and opened is defined as the front side of the crisper drawer 100. Figure 4 The diagram shown is a structural schematic of a food storage drawer 100.

[0170] The refrigerator also includes a water tank assembly 200. The water tank assembly 200 is detachably mounted on the side wall of the crisper drawer 100 by means of a vertical plug-in connection, and the water tank assembly 200 is configured to provide humidifying mist into the drawer cavity 110.

[0171] The side wall of the food storage drawer 100 is provided with a spray section 300, and the water box assembly 200 includes a water outlet section 220. The water outlet section 220 is configured to guide water in the water box assembly 200 to the spray section 300, and the spray section 300 is configured to provide humidifying mist into the drawer cavity 110.

[0172] This design employs a "top-and-bottom plug-in" method to detachably mount the water tank assembly 200 to the side wall of the food storage drawer 100. During installation, the user can directly insert the water tank assembly 200 vertically downwards along the plug-in structure on the side wall, without the need for precise alignment of complex clips. During disassembly, simply pull upwards to detach the water tank assembly 200 from the plug-in structure; the operation conforms to the natural force application habits of the human body. This design significantly reduces the difficulty of installing and removing the water tank assembly 200, reduces user operation time, and improves the convenience of daily maintenance (such as adding water and cleaning).

[0173] In existing technologies, the water tank and atomizing plate 310 are integrated into one unit, which can easily lead to water circuit interruption or poor contact of the atomizing plate 310 when disassembled or moved. This solution optimizes the humidification chain through a separate design of "water outlet 220-spray section 300".

[0174] The spray unit 300 is fixed to the side wall of the food storage drawer 100 to ensure stable atomization position; the water outlet 220 of the water box assembly 200 automatically connects with the spray unit 300 when plugged in to achieve water circuit conduction and avoid the problem of unstable water supply caused by installation deviation in traditional integrated designs.

[0175] The precise alignment of the water box assembly 200 and the spray unit 300 ensures a continuous and stable supply of water to the spray unit 300, keeping the atomizing plate 310 in optimal working condition. This ensures uniform humidity within the drawer cavity 110, reduces the risk of food spoilage due to localized dryness or excessive moisture, and extends the shelf life.

[0176] Existing water tanks are difficult to clean thoroughly due to their installation structure limitations, making them prone to mold growth and affecting food hygiene. This solution addresses this by allowing the water tank component 200 to be completely removed from the side wall, facilitating deep cleaning of the water storage chamber 213 and the water outlet 220, reducing scale and impurity residue.

[0177] In some embodiments of this application, reference is made to Figure 7 The refrigerator also includes an electrical component 420. (See reference...) Figure 9 The power-requiring component 420 is connected to the power-consuming component (e.g., atomizing plate 310) of the water box assembly 200 via a second electrical line 440. The power-requiring component 420 is disposed on the side wall of the food preservation drawer 100.

[0178] Reference Figure 7The refrigerator also includes a power supply component 410. The power supply component 410 is disposed on the side wall of the mounting chamber where the crisper drawer 100 is located. For example, in some embodiments, the crisper drawer 100 is slidably connected to the inner wall of the inner liner 20, in which case the power supply component 410 is disposed on the inner wall of the inner liner 20. As another example, in some embodiments, a drawer mounting rack 600 is provided in the refrigerator compartment 50, and the crisper drawer 100 is slidably connected to the drawer mounting rack 600, in which case the power supply component 410 is disposed on the drawer mounting rack 600.

[0179] When the food storage drawer 100 is closed, the power-demanding component 420 is in contact with the power supply component 410 to conduct the circuit. When the food storage drawer 100 is open, the power-demanding component 420 is separated from the power supply component 410 to disconnect the circuit.

[0180] The linkage design of the power-requiring component 420 and the power supply component 410 (conducting when the drawer is closed and disconnecting when it is opened) improves the stability of the humidification system while ensuring electrical safety and optimizing energy consumption through the coordination of circuit and mechanical action.

[0181] In existing technologies, if electrical components such as the atomizing plate 310 are continuously powered, users may directly contact the live parts or be splashed with water when opening the drawer to take out or put in food or disassembling the water box assembly 200, potentially causing a short circuit. This solution automatically controls the circuit's on / off state based on the drawer's open / closed status.

[0182] When the food storage drawer 100 is pulled forward and opened, the electrical component 420 moves synchronously with the drawer side wall, naturally separating from the power supply component 410 fixed to the side wall of the mounting chamber (such as the inner wall of the inner liner 20 or the drawer mounting bracket 600), and the circuit is instantly disconnected. At this time, electrical components such as the atomizing plate 310 stop working, preventing users from coming into contact with live structures when cleaning the water tank or organizing food, thus fundamentally eliminating the risk of electric shock or short circuit.

[0183] When the drawer is closed, the electrical component 420 and the power supply component 410 automatically conduct the circuit through contact (such as flexible contact mating), eliminating the need for manual operation by the user. The contact position is designed on the mating surface between the drawer side wall and the mounting chamber side wall, which reduces the corrosion of the contacts by dust and moisture, and lowers the risk of electrical sparks caused by poor contact.

[0184] In traditional designs, the atomizing plate 310 may continue to operate when the drawer is open, causing mist to leak out (unable to reach the drawer cavity 110) and wasting energy. This solution's linkage control enables "on-demand power supply." When the drawer is open, even if the water tank assembly 200 is still installed, the atomizing plate 310 stops spraying after the circuit is disconnected, preventing mist from spreading to other areas of the refrigerator compartment and avoiding frost buildup or cross-contamination of odors in non-fresh areas due to abnormal humidity. During drawer opening (e.g., 1-2 minutes when the user is taking out or putting in food), the circuit is completely disconnected, resulting in greater energy savings than traditional standby mode. Long-term use reduces unnecessary power consumption, aligning with the design trend of green appliances.

[0185] The power-requiring component 420 is installed on the side wall of the food storage drawer 100, adjacent to the water outlet 220 and spray section 300 of the water box component 200, which can shorten the length of the second power line 440 and reduce the risk of wire tangling; the power supply component 410 is fixed on the side wall of the installation chamber, without occupying the internal storage space of the drawer, and complements the space utilization of the side wall installation scheme of the water box component 200.

[0186] There is no rigid connection between the power-requiring component 420 that slides out of the drawer and the fixed power supply component 410, which avoids wear or breakage caused by dragging the wires and ensures that the drawer can maintain the reliability of circuit continuity even after long-term reciprocating motion.

[0187] In some embodiments of this application, the refrigerator further includes an air supply duct, and the air supply duct (not shown) is formed on the back side of the inner liner 20.

[0188] The refrigerator also includes a control panel (not shown), which is disposed in the air supply duct.

[0189] The power supply component 410 is connected to the control board via a first electrical line 430, which extends along the side wall of the mounting chamber where the refrigerated drawer 100 is located. For example, in some embodiments, the refrigerated drawer 100 is slidably connected to the inner wall of the inner liner 20, in which case the first electrical line 430 extends along the interior of the inner liner 20. As another example, in some embodiments, a drawer mounting bracket 600 is provided in the refrigerator compartment 50, and the refrigerated drawer 100 is slidably connected to the drawer mounting bracket 600, as shown in the figure. Figure 3 or Figure 12 Then the first electrical line 430 extends along the drawer mounting bracket 600.

[0190] The control board, as the core of the humidification system (e.g., regulating the operating frequency of the atomizing element 310 and monitoring humidity sensor signals), generates heat during operation. The continuously flowing cool air within the air duct quickly dissipates this heat, preventing chip performance degradation or circuit aging caused by high temperatures. Compared to placing the control board in a confined space (such as inside a drawer), the dynamic airflow within the duct keeps temperature fluctuations within a smaller range, ensuring stable control logic and reducing malfunctions in the humidification system (such as abnormal start-up and shutdown of the atomizing element 310).

[0191] Although there is cold air flowing inside the air duct, the humidity is lower than in other areas of the refrigerator compartment 50 (such as the crisper drawer 100), and the duct structure reduces the direct contact of condensate with the control board. The circuit components of the control board (such as capacitors and resistors) are sensitive to humidity. A low-humidity environment reduces the risk of short circuits or corrosion, making it particularly suitable for the high-humidity conditions inside the refrigerator compartment 50 and extending the lifespan of the control board.

[0192] The first electrical line 430 connects the power supply component 410 to the control board and extends along the side wall of the mounting chamber of the refrigerator drawer 100 (such as the inner wall of the inner liner 20) or the drawer mounting bracket 600. This concealed wiring along the side wall or mounting bracket completely avoids the storage area and pull-out path of the refrigerator drawer 100, preventing food storage obstruction or drawer jamming due to exposed wiring. Compared to traditional designs where wiring is arbitrarily arranged within the refrigerator compartment 50, this solution maximizes the effective storage volume, adapting to the storage needs of large-volume foods.

[0193] When the wiring extends along a fixed structure (side wall or mounting bracket), it can be secured using clips, wire grooves, or other methods to prevent friction with other components (such as food items or drawer edges) when the drawer is pulled out. For example, when the food storage drawer 100 is slidably connected to the inner wall of the inner liner 20, the first electrical line 430 runs along the wire groove on the inner wall of the inner liner 20, maintaining a safe distance from the drawer's movement trajectory. When the drawer is fitted with the mounting bracket, the wiring is arranged along the side groove of the mounting bracket, naturally concealed by the bracket structure, reducing wear or breakage of the wiring sheath caused by long-term reciprocating motion.

[0194] In some embodiments of this application, reference is made to Figure 4 or Figure 12 A drawer mounting bracket 600 is provided in the installation cavity where the food preservation drawer 100 is located. The drawer mounting brackets 600 are provided on opposite sides of the food preservation drawer 100. The food preservation drawer 100 is pulled out and mounted on the drawer mounting brackets 600. At least one of the drawer mounting brackets 600 is provided with the power supply component 410 on the side wall facing the food preservation drawer 100. A gap is formed between the drawer mounting bracket 600 and the inner liner 20. The first electrical line 430 extends along the gap.

[0195] The drawer mounting brackets 600 on both sides form a symmetrical support structure, which can evenly distribute the weight of the food storage drawer 100 (especially when storing a lot of food), and prevent the drawer from tilting or jamming due to force on one side. Compared with the design that relies solely on the inner wall of the inner liner 20 for guidance, the drawer mounting brackets 600 have higher precision slide rails (such as ball bearing slides or wear-resistant plastic guide rails), which can reduce the frictional resistance when the drawer is pulled out, making the operation smoother, and at the same time reducing the wear rate after long-term use.

[0196] The drawer mounting bracket 600 provides a stable mounting platform for the power supply component 410. When the power supply component 410 is positioned on the side wall of the drawer mounting bracket 600 facing the food storage drawer 100, the rigid structure of the drawer mounting bracket 600 ensures the positional accuracy of the power supply component 410 (such as contact height and levelness), reduces positional deviation caused by drawer vibration or temperature changes, and thus ensures reliable docking with the power-requiring component 420.

[0197] The gap between the drawer mounting bracket 600 and the inner liner 20 provides a dedicated routing channel for the first electrical circuit 430. Located between the drawer mounting bracket 600 and the inner liner 20, the gap allows the wiring to extend naturally along it, completely avoiding the storage area and movement path of the refrigerator drawer 100. Compared to designs where the wiring is exposed inside the refrigerator compartment 50, this solution prevents users from accidentally touching the wiring when retrieving food, and also avoids hygiene hazards caused by direct contact between the wiring and food (such as oil contamination of the wiring insulation).

[0198] The relatively enclosed space reduces the direct corrosion of wiring by condensation and mist within the refrigerator compartment. Wiring can be secured with cable ties or clips along the gaps to prevent loosening or sagging caused by bumps during refrigerator transport or vibrations from drawers. For example, plastic cable channels can be pre-installed within the gaps, allowing the wiring to pass through while isolating moisture and reducing friction and wear.

[0199] In some embodiments of this application, reference is made to Figure 9 or Figure 13 The power supply component 410 is connected to the power-consuming component of the water box component 200 via a second electrical line 440, which extends along the bottom wall of the slot 120.

[0200] The second electrical line 440 connects the power-requiring components 420 and the power-consuming parts (such as the atomizing plate 310) of the water box assembly 200, and extends along the bottom wall of the slot 120. This design, through deep integration with the structure of the slot 120, ensures circuit safety, optimizes space utilization, and improves the reliability and assembly efficiency of the system.

[0201] The slot 120 serves as the mounting carrier for the water box assembly 200, and its bottom wall provides a natural protective space for the second electrical line 440. The second electrical line 440 is fixed along the preset groove or slot on the bottom wall of the slot 120. After the water box assembly 200 is installed into the slot 120, its bottom is in contact with the bottom wall of the slot 120, and the line is constrained within the gap between the two, preventing it from being squeezed and deformed due to the weight of the water box assembly 200 or friction during installation and removal.

[0202] The second electrical line 440 extends along the bottom wall of the slot 120 and is completely within the mating space between the water box assembly 200 and the slot 120. It neither protrudes from the drawer cavity 110 nor occupies the water storage cavity 213 or the atomizing area of ​​the water box assembly 200.

[0203] The second electrical circuit 440 is secured along the bottom wall of the slot 120 using clips, adhesive, or embedded slots. This effectively restricts circuit displacement, especially during frequent installation and removal of the water box assembly 200 or when the drawer is pulled out and vibrated, preventing the connectors from coming loose due to pulling or shaking (such as loosening of the wiring terminals with the atomizing plate 310). A stable circuit connection ensures a continuous power supply to electrical components such as the atomizing plate 310, reducing humidification interruptions caused by power outages and ensuring stable humidity within the drawer cavity 110.

[0204] Slot 120 is the direct mounting location for the water box assembly 200. The second electrical line 440, running along the bottom wall, minimizes the distance between the power-requiring component 420 and the power-consuming component (atomizing plate 310). The second electrical line 440 extends directly from the power-requiring component 420 along the bottom wall of slot 120 to the atomizing plate 310. This short and redundant path reduces signal attenuation or voltage drop in low-voltage circuits (such as the drive circuit of the atomizing plate 310), ensuring stable operating power of the atomizing plate 310 and avoiding fluctuations in mist output due to insufficient power supply.

[0205] In some embodiments of this application, reference is made to Figure 15 and Figure 16 The power-requiring component 420 includes a mounting base 422, which is disposed on the side wall of the food storage drawer 100, as shown in the figure. Figure 8 , Figure 9 , Figure 13 as well as Figure 14 For example, the side wall of the food storage drawer 100 is provided with an installation opening, and the mounting base 422 is fixedly installed in the installation opening by a snap-fit ​​method.

[0206] The power-requiring component 420 further includes a second contact 421, which is disposed on the mounting base 422 and connected to the power-consuming component of the water box assembly 200 via a second electrical line 440. The power supply component 410 includes a first contact (not shown), which contacts the second contact 421 to conduct the circuit.

[0207] Mounting bracket 422 is made of insulating material (such as ABS plastic) to prevent short circuits. At the same time, the outline of mounting bracket 422 can form a protective wall to prevent condensation and food debris in the refrigerator compartment 50 from directly contacting the contacts, reducing poor contact caused by oxidation or contamination, and is especially suitable for long-term use in high humidity environments.

[0208] The first and second contacts 421 typically employ elastic structures (such as metal springs or spring probes). Upon contact, deformation can compensate for installation errors (such as slight misalignment of a drawer pull-out), ensuring a tight fit between the contact surfaces. Compared to rigid contacts, the elastic design reduces momentary disconnections caused by vibrations (such as refrigerator operation or drawer pull-out), ensuring continuous power supply to electrical components such as the atomizing plate 310 and preventing interruptions during humidification.

[0209] The second contact 421 is connected to the electrical components of the water box assembly 200 via the second electrical line 440, which runs along the bottom wall of the slot 120. The first contact is connected to the control board via the first electrical line 430, which extends along the drawer mounting bracket 600. As intermediate nodes in the circuit, the contact's position is designed to minimize the path between the two lines, reducing signal loss and forming a highly efficient power supply link: "control board - first contact - second contact 421 - atomizing plate 310".

[0210] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0211] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
