Description

Technical Field

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

[0002] One publicly available 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 a top-bottom configuration. Removing the water tray requires prying up one end and then pulling it vertically, 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 an inner liner forms a refrigerator compartment; a fresh-keeping drawer is disposed in the refrigerator compartment; a cover is disposed in the refrigerator compartment and configured to close the top opening of the drawer compartment; a mounting bracket is disposed on the side of the cover facing the drawer compartment, and a slot is formed on the mounting bracket, the slot having an opening facing horizontally; a water tank assembly is configured to be inserted into or removed from the slot through the opening of the slot in the horizontal direction, and the water tank assembly is configured to provide humidifying mist to the drawer compartment.

[0007] The above technical solution has the following advantages or beneficial effects:

[0008] The water tank assembly is inserted or removed horizontally through the slot opening. Taking the front opening of the slot as an example, users only need to insert or pull the water tank assembly horizontally. This horizontal insertion and removal method is more ergonomic, making the operation easier and more convenient, greatly reducing the difficulty for users to disassemble and install the water tank assembly, and improving the user experience.

[0009] The mounting bracket is located on the side of the cover facing the drawer cavity, and it has a slot with a horizontal opening for installing the water tank assembly. This mounting bracket provides a stable base for the water tank assembly, ensuring it won't shake or shift during refrigerator operation and guaranteeing its proper function. Furthermore, the method of fixing the mounting bracket to the cover is simple and reliable, which helps improve production assembly efficiency and reduce production costs.

[0010] 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 further includes a water outlet, the water box body has an installation port, and the water outlet is located at the installation port; a spray section is provided on the slot, and the spray section is located below the water outlet; wherein, the water outlet is configured to guide water in the water storage cavity to the spray section when the water box body is installed in the slot, and the spray section provides humidifying mist into the drawer cavity; the water outlet is also configured to close when the water box body is removed from the slot to prevent water in the water storage cavity from flowing out.

[0011] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0012] When the water tank is installed in the slot, the water outlet at the mounting opening on the bottom wall of the water tank precisely aligns with the spray nozzle on the slot (the spray nozzle is located below the water outlet). At this time, the water outlet steadily guides the water from the storage chamber to the spray nozzle, ensuring a continuous water supply. With this water supply, the spray nozzle releases humidifying mist into the drawer cavity, creating a suitable humidity environment for the food.

[0013] When users need to disassemble the water tank components (such as for cleaning, water replacement, or maintenance), the water outlet will automatically close, effectively solving the problem of residual water leakage in the water storage chamber when traditional water tanks are disassembled.

[0014] The opening and closing state of the water outlet is linked to the installation / removal of the water box assembly, eliminating the need for users to manually operate valves and other components, thus achieving an automated effect of "water supply upon installation and shutdown upon removal".

[0015] 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;

[0016] 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;

[0017] 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.

[0018] 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.

[0019] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0020] The components of the water outlet form a complete mechanical linkage system: based on the first mounting base, the moving parts are the transmission core, the elastic parts provide the reset power, the sealing parts perform the sealing action, and the automatic on / off is achieved by the change of external force (contact / separation with the spray part) when the water box assembly is installed / removed.

[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 among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0023] When the water box assembly is installed into the slot, the spray unit applies a force to the second moving part. This force is efficiently transmitted to the sealing member in the water storage chamber through the rod-shaped first moving part, so that the sealing member is precisely disengaged from the water outlet to open the water outlet gap. When the water box assembly is removed, the restoring force of the elastic element is also transmitted to the sealing member through the first moving part, so that it fits tightly against the water outlet to achieve a seal.

[0024] 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.

[0025] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0026] The first mounting base has an opening on the side facing the spray section, through which the second moving part protrudes. This design provides a structural basis for direct contact between the moving part and the spray section. When the water tank assembly is inserted into the slot horizontally, the exposed second moving part can be precisely aligned with the spray section first. The edge of the opening acts as a guide, preventing misalignment and collision between the moving part and the spray section, and ensuring smooth contact between the two.

[0027] The water outlet is located on the second moving part. When the second moving part comes into contact with the spray part, the outlet end of the water outlet is closely connected with the water inlet area of ​​the spray part, which reduces water loss and splashing during the transmission process and improves water resource utilization.

[0028] When the water outlet and the spray unit align, the second moving part contacts the spray unit, generating thrust that causes the moving component to overcome the elastic force of the elastic component and move towards the water storage chamber. The water outlet gap opens, and water from the storage chamber flows sequentially through the water inlet and the water flow chamber into the area of ​​the second moving part. At this time, water from the water flow chamber flows evenly to the spray unit through multiple circumferentially arranged water outlets. With a water supply, the spray unit stably generates humidifying mist and releases it into the drawer cavity, providing suitable humidity for food preservation. This structural synergy in the aligning state achieves a continuous process of "contact equals water flow, water flow equals atomization."

[0029] In some embodiments of this application, the spray section includes an atomizing plate, and the slot has a spray nozzle on the side wall facing the drawer cavity, with the atomizing plate covering the spray nozzle;

[0030] The spray unit also includes a second mounting base, which is disposed in the slot. The second mounting base is provided with a first water inlet, and a first water storage chamber is formed between the second mounting base and the atomizing plate. The first water inlet connects the first water storage chamber with the water outlet.

[0031] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0032] The first water storage chamber, formed between the second mounting base and the atomizing plate, is located above the atomizing plate. Its core function is to temporarily store and buffer the incoming water flow. When the water outlet supplies water to the first water inlet, the water flow first enters the first water storage chamber, and then the water storage chamber supplies water to the atomizing plate.

[0033] When the water box assembly is installed in place, the water outlet of the water outlet precisely aligns with the first water inlet of the second mounting base. Water flows smoothly into the first water storage chamber through the first water inlet, and then supplies the atomizing plate from the first water storage chamber. The rigid structure of the second mounting base effectively resists the impact force during the installation of the water box assembly and the vibration of the atomizing plate during operation, ensuring the stability of each component and preventing water leakage or a decrease in atomization effect due to structural loosening.

[0034] In some embodiments of this application, the first mounting base has a groove on the side facing the water box assembly, the water outlet closes the opening of the groove to form a second water storage chamber, and the second mounting base has a second water inlet that connects the first water storage chamber and the second water storage chamber.

[0035] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0036] The first mounting base has a groove on the side facing the water box assembly. A second water storage chamber, formed by the water outlet closing the opening of the groove, connects the first and second water storage chambers through a second water inlet after the water box assembly is installed. When the water outlet supplies water to the first water storage chamber, the first chamber prioritizes storing water until it is full. Excess water then flows upwards into the second water storage chamber through the second water inlet. This design makes the second water storage chamber a direct "expansion space" for the first water storage chamber, significantly increasing the total water storage capacity of the entire humidification system.

[0037] In some embodiments of this application, the slot has a mounting groove on the side wall facing the drawer cavity, the spray unit is disposed in the mounting groove, and the spray nozzle is disposed on the bottom wall of the mounting groove.

[0038] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0039] The mounting slot provides a precise installation and positioning space for the spray unit. The mounting slot forms a circumferential enclosure around the spray unit, which can effectively prevent food or other debris in the drawer cavity from directly contacting the spray unit, reduce the interference of external factors on the operation of the atomizing plate, and play a protective role.

[0040] In some embodiments of this application, the mounting bracket is provided with a cable routing channel.

[0041] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0042] The wiring channels on the mounting bracket are specifically designed for extending the wiring of the atomizing plate's circuitry, providing the wiring with an independent and enclosed channel. This design isolates the wiring from other structures such as the water box assembly and spray nozzle, preventing the wiring from coming into contact with the water flow or being squeezed or worn by moving parts, thus reducing safety hazards such as short circuits and leakage.

[0043] In some embodiments of this application, a refrigerator is provided, wherein an inner liner forms a refrigerator compartment; a fresh-keeping drawer is disposed in the refrigerator compartment, and a drawer cavity is formed in the fresh-keeping drawer; a cover is disposed in the refrigerator compartment, and the cover is configured to close the top opening of the drawer cavity; a mounting bracket is disposed on the side of the cover facing the drawer cavity, and a wiring groove is provided on the mounting bracket; a water box assembly is detachably disposed on the mounting bracket, and the electrical wiring of the electrical components of the water box assembly extends along the wiring groove, and the water box assembly is configured to provide humidifying mist to the drawer cavity.

[0044] The above technical solution has the following advantages or beneficial effects:

[0045] The mounting bracket provides a stable mounting base for the water tank assembly, allowing it to be securely installed on the side of the cover facing the drawer cavity. During refrigerator operation, even when subjected to vibrations or the pulling out of the crisper drawer, the water tank assembly is not prone to shaking or displacement, ensuring stable operation of its humidifying mist supply function to the drawer cavity.

[0046] The mounting bracket is equipped with cable trays, along which the electrical wiring for the water box assembly can be routed. This design makes the wiring layout more organized and avoids messy, tangled wiring.

[0077] There are multiple doors 30, and each door 30 corresponds to a storage room.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] The food storage drawer 100 has a drawer cavity 110 inside, and the top of the drawer cavity 110 is open to facilitate the retrieval or placement of items.

[0082] The refrigerator also includes a cover. The cover is located inside the refrigerator compartment 50 and is configured to close the top opening of the drawer cavity 110. When the crisper drawer 100 is closed, the drawer door of the crisper drawer seals against the front side of the cover to form a closed drawer space.

[0083] In some embodiments, 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. Figure 4 for Figure 3 The diagram shown omits the drawer doors. For example, shelf 40 is a transparent glass shelf.

[0084] In other embodiments, the refrigerator compartment 50 is specially provided with a cover structure for closing the top opening of the food storage drawer 100. This cover structure is a separate structure from the shelf.

[0085] The refrigerator also includes a mounting bracket 400. Figure 11 This is a structural diagram of mounting bracket 400. (Refer to...) Figure 4 and Figure 5 The mounting bracket 400 is disposed on the side of the cover plate facing the drawer cavity 110.

[0089] The water tank assembly 200 is inserted or removed horizontally through the opening of the slot 410. Taking the front opening of the slot 410 as an example, the user only needs to insert or pull out the water tank assembly 200 horizontally. This horizontal insertion and removal method is more ergonomic, making the operation easier and more convenient, greatly reducing the difficulty for users to disassemble and install the water tank assembly 200, and improving the user experience.

[0090] In some embodiments, the refrigerator compartment 50 is provided with a shelf 40, beneath which the crisper drawer 100 is located. The shelf 40 can also serve as a top cover for the crisper drawer 100. If a transparent glass shelf is used, it serves both as a cover and allows the user to easily observe the items inside the crisper drawer 100. In other embodiments, a cover structure independent of the shelf 40 is specifically provided. This diverse design can be selected according to different product positioning and user needs, improving the flexibility and adaptability of the refrigerator's internal structure design.

[0091] The mounting bracket 400 is located on the side of the cover plate facing the drawer cavity 110, for example, by adhesive bonding to the bottom side of the mounting bracket 400. The mounting bracket 400 has a slot 410 with a horizontal opening for mounting the water tank assembly 200. The mounting bracket 400 provides a stable mounting base for the water tank assembly 200, ensuring that the water tank assembly 200 will not shake or shift during refrigerator operation, thus ensuring its normal operation. At the same time, the fixing method between the mounting bracket 400 and the cover plate is simple and reliable, which helps improve production assembly efficiency and reduce production costs.

[0092] The water tank assembly 200 is configured to provide humidifying mist into the drawer cavity 110 to improve the preservation of food inside the drawer. The stable installation and convenient operation of the water tank assembly 200 ensure the continuous and stable operation of the humidification function. Users can easily maintain the water tank assembly 200, such as adding water and cleaning, thereby ensuring a normal supply of humidifying mist, providing a suitable humidity environment for the food inside the drawer, extending the shelf life of the food, reducing nutrient loss and deterioration in taste caused by dryness, and better meeting users' needs for food preservation.

[0093] In some embodiments of this application, a refrigerator is provided, as shown in the reference... Figure 1 and Figure 2 The refrigerator includes an inner liner 20, which forms a refrigerator compartment 50.

[0094] The refrigerator also includes a fresh food drawer 100, which is disposed in the refrigerator compartment 50, and a drawer cavity 110 is formed in the fresh food drawer 100.

[0095] Reference Figure 2 and Figure 3 The refrigerator also includes a cover plate disposed within the refrigerator compartment 50, the cover plate being configured to close the top opening of the drawer cavity 110.

[0096] Reference Figure 4 , Figure 5 , Figure 8 as well as Figure 11 The refrigerator also includes a mounting bracket 400, which is located on the side of the cover plate facing the drawer cavity 110, and the mounting bracket 400 is provided with a wiring groove 420.

[0097] Reference Figure 8 The refrigerator also includes a water box assembly 200, which is detachably mounted on the mounting bracket 400. The electrical wiring of the electrical components of the water box assembly 200 extends along the wiring groove 420. The water box assembly 200 is configured to provide humidifying mist into the drawer cavity 110.

[0098] The mounting bracket 400 provides a stable mounting base for the water tank assembly 200, allowing it to be securely mounted on the side of the cover facing the drawer cavity 110. During refrigerator operation, even when subjected to vibration or the pulling of the crisper drawer 100, the water tank assembly 200 is not prone to shaking or displacement, ensuring stable operation of its humidifying mist supply function to the drawer cavity 110.

[0099] Because the water box assembly 200 is easy to install and remove, users can maintain it in a timely manner to ensure the continuous effectiveness of the humidification function. At the same time, stable installation and standardized wiring ensure the normal operation of electrical components such as the atomizing plate 310, so that the humidifying mist can be stably supplied to the drawer cavity 110.

[0100] The mounting bracket 400 is equipped with a cable tray 420, along which the electrical wiring of the water box assembly 200 can be extended. This design makes the wiring layout more orderly and avoids messy and tangled wiring.

[0101] In some embodiments of this application, reference is made to Figure 9 and Figure 10 The water box assembly 200 includes a water box body 210, and a water storage cavity 213 is formed inside the water box body 210. For example, the water box body 210 has a cuboid structure, and correspondingly, the slot 410 also has a cuboid structure.

[0102] A water inlet is provided on the top wall of the water box body 210, and a plug 211 is provided at the water inlet. Water is injected into the water storage chamber 213 through the water inlet.

[0103] Reference Figure 6 , Figure 7 as well as Figure 10 The water box assembly 200 further includes a water outlet 220. The water box body 210 has an installation port, and the water outlet 220 is located at the installation port. Specifically, the bottom wall of the water box body 210 has an installation port, and the water outlet 220 is located at the installation port on the bottom wall of the water box body 210.

[0104] Reference Figure 7 , Figure 11 and Figure 12 The slot 410 is provided with a spray section 300, which is located below the water outlet section 220.

[0105] Reference Figure 7 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 410, and the spray section 300 provides humidifying mist to the drawer cavity 110.

[0106] The water outlet 220 is also configured to close when the water box body 210 is removed from the slot 410 to prevent water from flowing out of the water storage chamber 213.

[0107] When the water tank body 210 is installed in the slot 410, the water outlet 220 at the mounting opening on the bottom wall of the water tank body 210 precisely aligns with the spray unit 300 on the slot 410 (the spray unit 300 is located below the water outlet 220). At this time, the water outlet 220 stably guides the water in the water storage chamber 213 to the spray unit 300, ensuring that the spray unit 300 can continuously obtain a water source. With the water supply, the spray unit 300 releases humidifying mist into the drawer cavity 110, creating a suitable humidity environment for the food. This structural design achieves high efficiency and stability in water supply transmission, avoiding the problems of water supply interruption or unstable spray volume in traditional humidification structures, and ensuring consistent preservation effects.

[0108] When the user needs to disassemble the water tank assembly 200 (such as for cleaning, water replacement, or maintenance), the water outlet 220 will automatically close. This feature effectively solves the problem of residual water leakage in the water storage chamber 213 when the traditional water tank is disassembled: the user does not need to empty the water storage chamber 213 in advance, and can directly remove the water tank assembly 200 from the slot 410. The sealing function of the water outlet 220 can firmly lock in the remaining water, preventing water from overflowing and contaminating the inside of the refrigerator or the user's hands.

[0109] The water outlet 220 and the spray nozzle 300 are positioned in tandem (the water outlet 220 is located on the bottom wall of the water box body 210, and the spray nozzle 300 is located below the water outlet 220). Gravity is used to assist the flow of water from the water storage chamber 213 to the spray nozzle 300, reducing reliance on additional power devices and lowering energy consumption and the risk of malfunction. Simultaneously, the opening and closing of the water outlet 220 is linked to the installation / removal of the water box assembly 200, eliminating the need for manual operation of valves and other components. This achieves an automated effect of "water flow upon installation, and shutdown upon removal," further enhancing the product's intelligence and ease of use.

[0110] In some embodiments of this application, reference is made to Figure 7 The water outlet 220 includes a first mounting base 221, which is disposed at the mounting port. For example, the first mounting base 221 is fixed to the mounting port by a snap-fit ​​method.

[0111] The first mounting base 221 has a water-carrying cavity 225 extending through both its upper and lower ends. A water outlet is provided on the first mounting base 221, and the water-carrying cavity 225 communicates with the water outlet. The water outlet connects the water-carrying cavity 225 to the water storage cavity 213. One end of the water-carrying cavity 225 has a water outlet, and the other end of the water-carrying cavity 225 communicates with the spray unit 300.

[0112] The water outlet 220 also includes a moving part 222, which passes through the water outlet and forms a water outlet gap 226 between the moving part 222 and the water outlet.

[0113] The water outlet 220 also includes an elastic element 223, which is disposed in 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 in a direction away from the water storage cavity 213.

[0114] 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.

[0115] The vertically penetrating water-carrying cavity 225 formed within the first mounting base 221 provides a stable channel for water flow. The water-carrying cavity 225 connects to the water storage cavity 213 via a water outlet, and its other end connects to the spray unit 300, forming a complete water flow path from the water storage cavity 213 to the spray unit 300. The structural design of the water-carrying cavity 225 ensures that the water flow does not diffuse randomly during transmission, avoiding water waste and moisture accumulation inside the water box body 210. It provides a structural carrier for the subsequent installation of moving parts 222, elastic parts 223, and other components, serving as the basic framework for the water outlet 220 to achieve its function.

[0116] The moving part 222 passes through the water outlet and forms a water outlet gap 226 with it. This gap is the key channel for water in the water storage chamber 213 to enter the water outlet chamber 225. When the water box assembly 200 is in different states, the position change of the moving part 222 will directly change the size of the water outlet gap 226: when water supply is needed, the water outlet gap 226 opens, and water can flow smoothly from the water storage chamber 213 through the water outlet and the water outlet chamber 225 to the spray section 300; when water supply needs to be cut off, the water outlet gap 226 is blocked, and the water flow is interrupted. The setting of the moving part 222 enables precise control of the water flow through mechanical movement. Compared with the traditional manual valve structure, it has a faster response, is more convenient to operate, and does not require additional user intervention, thus improving the user experience.

[0117] The elastic element 223 is disposed within the water inlet cavity 225, and its core function is to apply a force to the moving element 222 in a direction away from the water storage cavity 213. When the water box assembly 200 is removed from the slot 410, the elastic force of the elastic element 223 pushes the moving element 222 to move away from the water storage cavity 213, causing the sealing element 224 to move synchronously, ultimately sealing the water outlet gap 226 and preventing water leakage from the water storage cavity 213. When the water box assembly 200 is installed into the slot 410, the spray unit 300 applies a reverse force to the moving element 222 (in a direction closer to the water storage cavity 213). This force overcomes the elastic force of the elastic element 223, causing the moving element 222 to move in the opposite direction. At this time, the water outlet gap 226 opens, and the water supply is restored. The elastic force of the elastic element 223 provides a stable reset force for the moving element 222, ensuring that the water outlet 220 can automatically remain closed when there is no external force intervention (i.e., the water box assembly 200 is removed), achieving the automated effect of "sealing upon removal" and reducing the risk of leakage caused by human error.

[0118] The sealing component 224 is connected to the moving component 222, and its movement is directly driven by the moving component 222. It is the actuator that controls the opening and closing of the water outlet gap 226. When the moving component 222 moves away from the water storage chamber 213 under the action of the elastic component 223, the sealing component 224 moves accordingly and fits tightly against the edge of the water outlet, completely sealing the water outlet gap 226. The sealing effect of the contact surface prevents water from flowing through. At this time, even if there is water in the water storage chamber 213, it will not flow out from the water outlet chamber 225, effectively solving the leakage problem when disassembling traditional water boxes. When the water box assembly 200 is installed in place, when the moving component 222 moves towards the water storage chamber 213 under the reaction force of the spray section 300, the sealing component 224 disengages from the water outlet along with the moving component 222, the water outlet gap 226 opens, and the water in the water storage chamber 213 can enter the water outlet chamber 225 through the gap and flow to the spray section 300, ensuring the normal operation of the humidification function.

[0119] The components of the water outlet section 220 form a complete mechanical linkage system: based on the first mounting base 221, the moving part 222 serves as the transmission core, the elastic part 223 provides the reset power, and the sealing part 224 performs the sealing action. Automatic on / off switching is achieved through changes in external force (contact / separation with the spray section 300) during the installation / removal of the water box assembly 200. This structure does not rely on electronic control components; intelligent control of water flow can be achieved solely through mechanical structure, reducing costs and failure rates. At the same time, each component responds rapidly, with the entire process from removing the water box assembly 200 to closing it completed instantly, and there is no delay from installation to water flow activation, ensuring operational continuity and timely humidification.

[0120] In some embodiments of this application, reference is made to Figure 7 The moving part 222 includes a first moving part 2221. The first moving part 2221 is a rod-shaped structure. The first moving part 2221 passes through the water inlet, one end of the first moving part 2221 extends into the water storage cavity 213, and the other end of the first moving part 2221 is located in the water inlet 225.

[0121] The moving part 222 also includes a second moving part 2222. The first moving part 2221 and the second moving part 2222 are an integral structure. A sealing member 224 is provided at one end of the first moving part 2221, and the sealing member 224 is located in the water storage cavity 213. The second moving part 2222 is provided at the other opposite end of the first moving part 2221. The second moving part 2222 has a disc-shaped structure. The second moving part 2222 is located in the water flow cavity 225.

[0122] The elastic element 223 is sleeved on the outer periphery of the first moving part 2221. The elastic element 223 is disposed between the second moving part 2222 and the first mounting base 221. Specifically, one end of the elastic element 223 abuts against the second moving part 2222 and the other end abuts against the first mounting base 221.

[0123] The first moving part 2221 adopts a rod-shaped structure and passes through the water outlet. Its two ends extend into the water storage cavity 213 and the water outlet cavity 225, respectively, forming a rigid transmission path through the water outlet. This rod-shaped structure has good guiding properties, ensuring that the moving part 222 will not deviate or jam when moving axially (towards or away from the water storage cavity 213), thus ensuring the alignment accuracy between the sealing part 224 and the water outlet. When the water box assembly 200 is installed in the slot 410, the spray part 300 applies a force to the second moving part 2222. This force is efficiently transmitted to the sealing part 224 in the water storage cavity 213 through the rod-shaped first moving part 2221, causing the sealing part 224 to accurately disengage from the water outlet to open the water outlet gap 226. When the water box assembly 200 is removed, the restoring force of the elastic part 223 is also transmitted to the sealing part 224 through the first moving part 2221, making it tightly fit the water outlet to achieve a seal.

[0124] The second moving part 2222 has a disc-shaped structure and is integral with the first moving part 2221. It is located inside the water-carrying cavity 225 and at the end of the first moving part 2221 away from the sealing member 224. Its disc-shaped structure increases the contact area with the elastic member 223 and the spray part 300, making the force transmission more uniform and stable. When the spray part 300 pushes the moving part 222, the disc-shaped second moving part 2222 can disperse the force and prevent the first moving part 2221 from deforming due to excessive local force. At the same time, the elastic member 223 is sleeved on the outer periphery of the first moving part 2221 and one end abuts against the second moving part 2222. The disc-shaped structure provides a stable support surface for the elastic member 223, ensuring that the elastic member 223 will not be skewed during compression or reset, and ensuring that the direction of the elastic force is always along the axial direction of the first moving part 2221.

[0125] In some embodiments of this application, reference is made to Figure 7 and Figure 10 The first mounting base 221 has an opening on the side facing the spray section 300, and the second moving part 2222 is exposed from the opening.

[0126] The second moving part 2222 is provided with a water outlet 2223, which communicates with the water flow chamber 225. For example, multiple water outlets 2223 are provided, and the multiple water outlets 2223 are arranged circumferentially at intervals.

[0127] When the water outlet 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 2223.

[0128] The first mounting base 221 has an opening on the side facing the spray section 300, through which the second moving part 2222 protrudes. This design provides a structural basis for direct contact between the moving part 222 and the spray section 300. When the water box assembly 200 is inserted into the slot 410 horizontally, the exposed second moving part 2222 can be precisely aligned with the spray section 300 first. The edge of the opening acts as a guide, preventing misalignment and collision between the moving part 222 and the spray section 300, ensuring smooth contact between the two. At the same time, the size of the opening matches the shape of the second moving part 2222, ensuring that the second moving part 2222 can extend smoothly to transmit force, and also providing radial restraint to prevent the moving part 222 from swaying under force. This ensures that the thrust applied by the spray section 300 is accurately transmitted along the axial direction of the first moving part 2221, providing a reliable guarantee for the stable opening of the water outlet gap 226. In addition, the opening creates a communication channel between the water flow chamber 225 and the external space (the area where the spray unit 300 is located), providing a path for water to flow from the water flow chamber 225 through the water outlet 2223 to the spray unit 300.

[0129] The water outlets 2223 (especially the multiple circumferentially spaced water outlets 2223) provided on the second moving part 2222 significantly optimize the water flow distribution efficiency. When the water outlet gap 226 is opened, the water in the water storage chamber 213 enters the water flow chamber 225 through the water inlet, and the water in the water flow chamber 225 flows to the spray part 300 through the water outlets 2223. The multiple circumferentially spaced water outlets 2223 can evenly distribute the water flow to different areas of the spray part 300, avoiding the water flow concentration phenomenon caused by single-hole water outlet, so that the spray part 300 can make fuller use of the water source to generate humidifying mist and improve the humidification uniformity. The water outlets 2223 are provided on the second moving part 2222. When the second moving part 2222 comes into contact with the spray part 300, the outlet end of the water outlet 2223 is closely connected with the water inlet area of ​​the spray part 300, reducing water loss and splashing during the transmission process and improving water resource utilization.

[0130] When the water outlet 220 aligns with the spray section 300, the second moving part 2222 contacts the spray section 300, generating a thrust that causes the moving part 222 to overcome the elastic force of the elastic member 223 and move towards the water storage chamber 213. The water outlet gap 226 opens, and water from the water storage chamber 213 sequentially enters the area of ​​the second moving part 2222 through the water inlet and water flow chamber 225. At this time, water from the water flow chamber 225 flows evenly to the spray section 300 through multiple circumferentially arranged water outlets 2223. With a water supply, the spray section 300 stably generates humidifying mist and releases it into the drawer chamber 110, providing suitable humidity for food preservation. This structural synergy in the aligning state achieves a continuous process of "contact equals water flow, water flow equals atomization."

[0131] In some embodiments of this application, reference is made to Figure 7The spray section 300 includes an atomizing plate 310, and the slot 410 has a spray nozzle 440 on its side wall facing the drawer cavity 110, with the atomizing plate 310 covering the spray nozzle 440.

[0132] The spray unit 300 also includes a second mounting base 330, which is disposed within the slot 410. For example, the second mounting base 330 is fixedly installed within the slot 410 by means of plugging or snapping.

[0133] The second mounting base 330 is provided with a first water inlet 323. A first water storage cavity 321 is formed between the second mounting base 330 and the atomizing plate 310. The atomizing plate 310 is located below the first water storage cavity 321. The first water inlet 323 connects the first water storage cavity 321 with the water outlet 2223.

[0134] The atomizing plate 310, which covers the spray nozzle 440 on the side wall of the slot 410 facing the drawer cavity 110, is the core component for achieving water atomization. When water flows into the area where the atomizing plate 310 is located, the atomizing plate 310 disperses the water flow into fine mist particles through high-frequency vibration. These mist particles enter the drawer cavity 110 directly through the spray nozzle 440, providing a humidifying effect for the food.

[0135] The first water storage chamber 321, formed between the second mounting base 330 and the atomizing plate 310, is located above the atomizing plate 310. Its core function is to temporarily store and buffer the incoming water flow. When the water outlet 2223 supplies water to the first water inlet 323, the water flow first enters the first water storage chamber 321, and then the water storage chamber supplies water to the atomizing plate 310.

[0136] The first water inlet 323 on the second mounting base 330 connects the water outlet 2223 with the first water storage chamber 321, forming a complete water flow path from the water outlet 220 to the atomizing plate 310. When the water box assembly 200 is installed in place, the water outlet 2223 of the water outlet 220 precisely aligns with the first water inlet 323 of the second mounting base 330, allowing water to flow smoothly into the first water storage chamber 321 through the first water inlet 323, and then be supplied to the atomizing plate 310 by the first water storage chamber 321. The rigid structure of the second mounting base 330 effectively resists the impact force during the installation of the water box assembly 200 and the vibration during the operation of the atomizing plate 310, ensuring the stability of each component and preventing water leakage or a decrease in atomization effect due to structural loosening.

[0137] When the water box assembly 200 is installed into the slot 410, the water outlet 2223 of the water outlet 220 aligns with the first water inlet 323 of the second mounting base 330. Water flows through the first water inlet 323 into the first water storage chamber 321, and the water in the water storage chamber continuously supplies the atomizing plate 310 below. The atomizing plate 310 atomizes the water through high-frequency vibration, and the generated mist is sprayed into the drawer cavity 110 through the spray nozzle 440 to humidify the food.

[0138] In some embodiments of this application, reference is made to Figure 7 and Figure 12 The first mounting base 221 has a groove on the side facing the water box assembly 200, that is, a groove is provided on the upper side of the first mounting groove 430. The water outlet 220 closes the opening of the groove to form a second water storage chamber 322.

[0139] The second mounting base 330 is provided with a second water inlet 324, which connects the first water storage chamber 321 and the second water storage chamber 322. For example, multiple second water inlets 324 are provided, and the multiple second water inlets 324 are arranged at intervals around the first water inlet 323.

[0140] The first mounting base 221 has a groove on the side facing the water box assembly 200, and the water outlet 220 closes the opening of the groove to form a second water storage chamber 322. When the water box assembly 200 is installed in place, the water outlet 2223 of the water outlet 220 first introduces water into the first water storage chamber 321. When the first water storage chamber 321 is full, the water in the first water storage chamber 321 flows upward through the second water inlet 324 into the second water storage chamber 322, and the second water storage chamber 322 serves to expand the water storage space.

[0141] The first mounting base 221 has a groove on the side facing the water box assembly 200. The water outlet 220 closes the opening of the groove to form a second water storage chamber 322. After the water box assembly 200 is installed, it forms a water storage system that is vertically connected to the first water storage chamber 321 through the second water inlet 324. When the water outlet 2223 of the water outlet 220 supplies water to the first water storage chamber 321, the first water storage chamber 321 preferentially stores water until it is full. Excess water then flows upward into the second water storage chamber 322 through the second water inlet 324. This design makes the second water storage chamber 322 directly an "expansion space" for the first water storage chamber 321, significantly increasing the total water storage capacity of the entire humidification system.

[0142] The overflow water storage mode of the second water storage chamber 322 plays a crucial buffering role. When the water supply from the water outlet 2223 continuously exceeds the consumption of the atomizing plate 310, the overflow process after the first water storage chamber 321 is full prevents water from overflowing directly from the spray nozzle 440 or seeping into other areas inside the refrigerator. Instead, the water is guided in an orderly manner to the second water storage chamber 322 for temporary storage through the second water inlet 324. When the water level in the first water storage chamber 321 decreases due to atomization consumption, the water in the second water storage chamber 322 will flow back to the first water storage chamber 321 through the second water inlet 324 under the action of gravity, forming a dynamic balance of "water storage-overflow-return", ensuring that the atomizing plate 310 always has a stable water supply and avoiding the impact of water fluctuations on the humidification effect.

[0143] The first water inlet 323 continuously supplies water to the first water storage chamber 321, while the second water inlet 324 automatically adjusts the water flow direction according to the liquid level difference between the two chambers, ensuring that the water level in the first water storage chamber 321 is always maintained within a suitable range for the atomizing plate 310 to operate (neither too full, which would hinder atomization, nor too low, which would cause dry burning), significantly improving the operational stability of the humidification system. Furthermore, the design of multiple second water inlets 324 reduces the risk of overflow or backflow failure caused by blockage of a single channel 211. Even if individual water inlets are blocked by impurities 211, the remaining water inlets can still ensure normal bidirectional flow guidance, enhancing the reliability of the system.

[0144] The design of the second water storage chamber 322 and the second water inlet 324 further enhances the collaborative working efficiency with the water outlet 220 and the atomizing plate 310. The water outlet 2223 of the water outlet 220 supplies water to the first water storage chamber 321 through the first water inlet 323. The atomizing plate 310 continuously consumes the water in the first water storage chamber 321. When the water supply exceeds the consumption, the second water storage chamber 322 promptly receives the overflow to avoid waste. When the water supply is temporarily insufficient, the water stored in the second water storage chamber 322 is replenished through the second water inlet 324 to ensure that the atomizing plate 310 does not stop working.

[0145] The second water storage chamber 322 is formed by the groove of the first mounting base 221 and the water outlet 220, eliminating the need for additional large water storage components and maintaining structural compactness while expanding the water storage space. Its vertical arrangement with the first water storage chamber 321 makes full use of the longitudinal space between the mounting bracket 400 and the water box assembly 200, avoiding the occupation of the effective storage space of the drawer cavity 110, and taking into account both the humidification function and the practical storage needs of the refrigerator.

[0146] In some embodiments of this application, reference is made to Figure 7 and Figure 11The slot 410 has a mounting groove 430 on its side wall facing the drawer cavity 110. The spray unit 300 is disposed in the mounting groove 430, and the spray nozzle 440 is disposed on the bottom wall of the mounting groove 430. The first mounting base 221 is fixed in the slot 410 by means of plugging or snapping.

[0147] A third mounting base 340 is also fixedly disposed within the slot 410, and the atomizing plate 310 is disposed on the third mounting base 340. The third mounting base 340 is located between the second mounting base 330 and the bottom wall of the slot 410. For example, the third mounting base 340 is a rubber pad.

[0148] The slot 410 has a mounting groove 430 on its side wall facing the drawer cavity 110. The spray unit 300 is entirely disposed within the mounting groove 430, and a spray nozzle 440 is provided on the bottom wall of the mounting groove 430. The mounting groove 430 provides a precise installation and positioning space for the spray unit 300. The mounting groove 430 forms a circumferential enclosure around the spray unit 300, which can effectively prevent food or other debris in the drawer cavity 110 from directly contacting the spray unit 300, reducing the interference of external factors on the operation of the atomizing plate 310, and playing a protective role.

[0149] The third mounting base 340 is fixedly installed within the slot 410, located between the second mounting base 330 and the bottom wall of the slot 410. The atomizing plate 310 is mounted on the third mounting base 340, for example, using a rubber pad as the third mounting base 340. Rubber material has good elasticity and cushioning properties, effectively absorbing vibrations generated during the operation of the atomizing plate 310, reducing vibration transmission to the slot 410 and other refrigerator components, lowering operating noise, and improving the user experience. Simultaneously, the elastic deformation characteristics of the rubber pad allow the atomizing plate 310 to fit tightly against the bottom wall of the mounting slot 430, enhancing the seal at the spray nozzle 440, preventing mist leakage between the spray nozzle 440 and the atomizing plate 310, ensuring all mist enters the drawer cavity 110, and improving humidification efficiency. The third mounting base 340 also provides support and protection for the atomizing plate 310, preventing direct contact between the atomizing plate 310 and the hard bottom wall of the slot 410, thus extending the service life of the atomizing plate 310.

[0150] The mounting slot 430, the fixing method of the first mounting base 221, and the third mounting base 340 work together to form a stable and efficient spray unit 300 installation system. The mounting slot 430 provides basic positioning and protection, the first mounting base 221 ensures the stability of the overall structure through a convenient fixing method, and the third mounting base 340 further enhances the working stability of the atomizing plate 310 through buffering, sealing, and support. This synergistic effect allows the spray unit 300 to maintain good working condition under various operating conditions. Vibration of the atomizing plate 310, vibration of the refrigerator operation, or the pulling and pulling of the crisper drawer 100 will not significantly affect the humidification effect.

[0151] In some embodiments of this application, reference is made to Figure 11 The mounting bracket 400 is provided with a wiring groove 420. The electrical lines of the atomizing plate 310 extend along the wiring groove 420. A wire fixing part 421 is provided in the wiring groove 420 to fix the electrical lines in the wiring groove 420.

[0152] The wiring channel 420 on the mounting bracket 400 is specifically designed for the extension wiring of the atomizing plate 310, providing an independent and enclosed channel for the wiring. This design isolates the wiring from other structures such as the water box assembly 200 and the spray section 300, preventing the wiring from coming into contact with the water flow or being squeezed or worn by moving parts, thus reducing safety hazards such as short circuits and leakage.

[0153] In some embodiments of this application, an air supply duct (not shown) is formed on the back side of the inner liner 20. The refrigerator also includes a control board disposed within the air supply duct.

[0154] The atomizing plate 310 is connected to the control board via electrical wiring, which extends along the wiring groove 420. The wiring groove 420 extends towards the back of the inner liner 20.

[0155] The air duct on the back side of the inner liner 20 is a crucial channel for cold air circulation within the refrigerator. Placing the control panel within this duct allows for heat dissipation through the continuously flowing, low-temperature airflow. The control panel generates heat during operation, and the cool airflow environment quickly removes this heat, preventing performance degradation or malfunction due to overheating and ensuring long-term stable operation. Simultaneously, the relatively enclosed air duct, isolated from the food storage area, reduces the corrosive effects of moisture and odors from food on the control panel, lowering the risk of moisture and contamination and extending its lifespan.

[0156] The atomizing plate 310 is connected to the control board via electrical circuitry, achieving circuit integration between the two. The control board can automatically adjust the working state of the atomizing plate 310 (such as start / stop, atomization intensity, etc.) based on humidity detection data inside the refrigerator (such as feedback from the humidity sensor in the drawer cavity 110), making the humidification process more intelligent and precise.

[0157] The wiring channel 420 extends towards the back of the inner liner 20, providing a dedicated path for the electrical wiring to extend from the spray section 300 to the control panel within the air duct. This extension design allows the wiring to be arranged along a concealed area on the back of the inner liner 20, avoiding exposed wiring or wiring crossing the food storage area within the refrigerated space. This not only does not affect users' access to food but also reduces the risk of wiring being bumped or snagged by food, ensuring the safety and integrity of the wiring.

[0158] In some embodiments of this application, reference is made to Figure 10 A handle 212 is provided on the bottom side of the water tank body 210. (Refer to...) Figure 5 The bottom wall of the slot 410 has a notch through which the handle 212 protrudes. The handle 212 is provided for the user to hold and operate to easily remove the water box, making it convenient for the user to operate.

[0159] In some embodiments of this application, reference is made to Figure 9 The water box body 210 has a first snap-fit ​​part 214 on its outer wall and a second snap-fit ​​part 411 on its inner wall.
