Description

Technical Field

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

[0002] With the upgrading of consumption, in addition to low-temperature preservation, refrigerators have an increasingly urgent need for moisturizing fruits and vegetables, making humidification devices a core component of mid-to-high-end refrigerators. Ultrasonic atomization humidification is widely used due to its high efficiency and uniform water mist. Its water storage box needs to be detachable for water addition and cleaning to prevent bacterial growth. Therefore, the fixing mechanism between the water storage box and the shell has become a key technology.

[0003] In existing technologies, the implementation of refrigerator humidification devices mostly involves setting up a water storage structure and a spray component in the door or cabinet. The water storage structure is installed in a preset installation position by means of threaded connection, magnetic fixation, etc., to ensure the stability of the water storage structure under scenarios such as refrigerator door opening and closing and transportation bumps.

[0004] However, the threaded connection method locks the water storage box into the housing cavity with screws, which is structurally stable but requires tools to disassemble and is cumbersome to operate; the magnetic fixing method uses the magnetic attraction force to position the water storage box, which is easy to disassemble but the attraction force is easily affected by vibration and may loosen and shift after long-term use.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, according to a first aspect of the embodiments of this disclosure, a refrigerator is provided, comprising: The enclosure defines multiple cavities; A door, which is rotatably mounted on the housing to close or open the receiving cavity; A humidifying device is used to humidify the receiving cavity; the humidifying device includes: The housing has a mounting cavity. A water storage box is disposed within the mounting cavity, the water storage box forming a water storage chamber and a spray nozzle; the spray nozzle is configured to spray water mist toward the receiving cavity. A locking mechanism is used to fix the water storage box within the mounting cavity; the locking mechanism includes: Two hooks are provided with a first bend at one end of the hook near the spray nozzle. The two first bends are bent in opposite directions. The hooks are rotatably connected to the inner wall of the mounting cavity. An elastic element connects the two hooks at the ends away from the spray nozzle; a buckle is provided on the lower surface of the water storage box for movable contact with the first bent part; A pull rod is provided with a baffle at the end of the pull rod away from the spray nozzle, and the end of the hook away from the spray nozzle abuts against the baffle; The pull rod is used to drive the baffle to push the hook when the pull rod moves toward the spray nozzle, so that the hook rotates in the inner wall of the mounting cavity, while the two first bends move toward each other and disengage from the buckle.

[0008] In the above technical solution, the coordinated action of the hook, elastic element, and pull rod achieves both quick and stable locking of the water storage box and convenient unlocking, significantly optimizing the user experience. During installation, the first bend of the buckle and hook naturally engages, and the pre-tightening force of the elastic element keeps the hook locked, ensuring the water storage box remains stable and leak-proof during equipment operation or door rotation. To unlock, simply push the limiting post outside the housing; the pull rod will then drive the baffle to rotate the hook, causing the two first bends to move towards each other and disengage from the buckle, allowing for quick removal and water filling of the water storage box. Furthermore, the overall structure, through mechanical transmission and elastic pre-tightening, avoids the problem of elastic fatigue from long-term use of the buckle, ensuring locking stability, ease of operation, and long-term durability.

[0009] In some embodiments of this application, the ends of the two hooks away from the spray nozzle are further provided with a second bend, and the bending directions of the two second bends are opposite to each other; The baffles of the pull rod abut against the two second bends on the side away from the spray nozzle.

[0010] In the above technical solution, a second bend is added at the end of the hook away from the spray nozzle, and the pull rod baffle abuts against the side of the second bend away from the spray nozzle, which increases the contact area between the hook and the baffle and disperses the force during the transmission process. The second bend provides a precise and stable abutment point for the baffle, avoiding transmission failure problems such as slippage and offset when the pull rod pushes the hook, and ensuring that the force when the limit post slides can be efficiently transmitted to the hook.

[0011] In some embodiments of this application, the pull rod includes: A first sliding rod is used to cooperate with one of the second bends, and the baffle is disposed at the end of the first sliding rod away from the spray nozzle; A second sliding rod is used to cooperate with another second bend, and the baffle is disposed at the end of the second sliding rod away from the spray nozzle; A connecting rod is used to connect the first sliding rod and the second sliding rod, and the limiting post is located on the side of the connecting rod away from the water storage box.

[0012] In the above technical solution, the pull rod is divided into a first sliding rod, a second sliding rod, and a connecting rod. These, along with baffles corresponding to the two second bends, further improve the transmission synchronization and ease of operation of the locking mechanism. The first and second sliding rods can synchronously drive the baffles on both sides to act on the corresponding second bends, ensuring that the two hooks are subjected to balanced force and rotate synchronously around a fixed axis. This avoids problems such as unlocking jamming or uneven disengagement of the latches caused by lag in the action of one hook.

[0013] In some embodiments of this application, the inner surface of the housing is provided with a first sliding groove and a second sliding groove, the first sliding groove being used to install the first sliding rod, and the second sliding groove being used to install the second sliding rod.

[0014] In the above technical solution, a first sliding groove and a second sliding groove are provided on the inner surface of the housing corresponding to the first sliding rod and the second sliding rod. The sliding groove provides directional guidance for the sliding rod, ensuring that the first and second sliding rods can slide smoothly along a fixed trajectory, avoiding deviation or jamming, so that the force of the baffle on the second bending part is always accurately transmitted, driving the two hooks to rotate synchronously and smoothly, ensuring that the unlocking action is smooth and reliable.

[0015] In some embodiments of this application, a first stop is provided on the side of the first sliding groove near the second sliding groove. The first stop is fixedly installed on the inner surface of the housing. The first stop is located on the side of the second bent portion away from the spray nozzle. The first stop is used to limit one of the second bent portions.

[0016] In the above technical solution, a first stop fixed to the inner surface of the housing is added to the side of the first sliding groove near the second sliding groove. This stop is specifically designed to limit the second bending part on the corresponding side. It can disperse the force on the hook in the locked state, reduce the continuous contact force between the second bending part and the baffle, reduce component wear, and, together with the guiding effect of the sliding groove, ensure that the locking and unlocking actions of the hook are always kept within the preset trajectory. This not only ensures the stability of the water storage box during long-term use, but also makes the operation always smooth and effortless. It further adapts to the usage scenarios of frequent opening and closing and vibration of the refrigerator door, and enhances the overall reliability of the mechanism.

[0017] In some embodiments of this application, a second stop is provided on the side of the second sliding groove near the first sliding groove. The second stop is fixedly installed on the inner surface of the housing. The second stop is located on the side of the second bending portion away from the spray nozzle. The second stop is used to limit the second bending portion.

[0018] In the above technical solution, a second stop is added to the inner surface of the housing on the side of the second sliding groove near the first sliding groove. This stop is specifically designed to limit the second bending part on the corresponding side. It can disperse the force on the hook in the locked state, reduce the continuous contact force between the second bending part and the baffle, reduce component wear, and, together with the guiding effect of the sliding groove, ensure that the locking and unlocking actions of the hook are always kept within the preset trajectory. This not only ensures the stability of the water storage box during long-term use, but also makes the operation always smooth and effortless. It further adapts to the usage scenarios of frequent opening and closing and vibration of the refrigerator door, and enhances the overall reliability of the mechanism.

[0019] In some embodiments of this application, the water storage box is further provided with an atomizing chamber, which is connected to the spray nozzle; The atomizing chamber is provided with at least one atomizing element, which is used to convert the water in the water storage box into water mist and then spray it out from the spray nozzle.

[0020] In the above technical solution, an atomizing chamber is constructed separately within the water storage box, and at least one atomizing element is built in. The atomizing element converts the water in the water storage box into water mist, which is then sprayed out through the spray nozzle. This achieves an integrated layout of the atomizing structure while ensuring humidification effect and reliability. The atomizing chamber provides an independent and stable installation space for the atomizing element, preventing it from shaking or shifting during disassembly and transportation of the water storage box. It also isolates the atomizing element from the direct impact of the water in the water storage box, extending its service life.

[0021] In some embodiments of this application, an observation hole is provided on the water storage box, the observation hole is connected to the water storage cavity, and a transparent plate is provided inside the observation hole.

[0022] In the above technical solution, an observation hole connected to the water storage cavity is set on the water storage box and a transparent plate is embedded therein. The transparent plate not only ensures the sealing of the water storage cavity and prevents water leakage, but also allows users to directly observe the remaining water level and water quality through the observation hole without disassembling the water storage box. Users can decide whether to add water or clean the water in a timely manner based on the observation results, avoiding blind disassembly and simplifying the operation process.

[0023] In some embodiments of this application, the humidification device further includes a lighting element; The lighting element is disposed inside the water storage cavity and is fixed to the upper cavity wall of the water storage cavity.

[0024] In the above technical solution, an illumination element fixed to the upper cavity wall is added inside the water storage cavity, which can directly illuminate the inside of the water storage cavity, making it convenient for users to quickly observe the remaining water level. Users can determine whether water needs to be added without disassembling the water storage box. Combined with the quick unlocking structure of the water storage box, the water replenishment operation process is further simplified.

[0025] A second aspect of the embodiments of this application also discloses a refrigerator, comprising: The enclosure defines multiple cavities; A door, which is rotatably mounted on the housing to close or open the receiving cavity; A humidifying device is used to humidify the receiving cavity; the humidifying device includes: The housing has a mounting cavity and is mounted on the door body; A water storage box is disposed within the mounting cavity, the water storage box forming a water storage chamber and a spray nozzle; the spray nozzle is configured to spray water mist toward the cavity. A locking mechanism is used to fix the water storage box within the mounting cavity; the locking mechanism includes: Two hooks are provided, with a first bend at one end of the hook near the spray nozzle. The two first bends are bent in opposite directions, and the hooks are rotatably connected to the outer surface of the water storage box. An elastic element connects the two hooks at the ends furthest from the spray nozzle; A snap fastener is provided on the cavity wall of the mounting cavity for movable contact with the first bent portion; A pull rod is provided with a baffle at the end of the pull rod away from the spray nozzle, and the end of the hook away from the spray nozzle abuts against the baffle; The pull rod is used to drive the baffle to push the hook when the pull rod moves toward the spray nozzle, so that the hook rotates relative to the water storage box, and at the same time the two first bends move toward each other and disengage from the buckle.

[0026] In the above technical solution, the coordinated action of the hook, elastic element, and pull rod achieves both quick and stable locking of the water storage box and convenient unlocking, significantly optimizing the user experience. During installation, the first bend of the buckle and hook naturally engages, and the pre-tightening force of the elastic element keeps the hook locked, ensuring the water storage box remains stable and leak-proof during equipment operation or door rotation. To unlock, simply push the limiting post outside the housing; the pull rod will then drive the baffle to rotate the hook, causing the two first bends to move towards each other and disengage from the buckle, allowing for quick removal and water filling of the water storage box. Furthermore, the overall structure, through mechanical transmission and elastic pre-tightening, avoids the problem of elastic fatigue from long-term use of the buckle, ensuring locking stability, ease of operation, and long-term durability.

[0030] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0034] As consumers' demands for food preservation quality continue to rise, refrigerator compartment environmental control technology is facing new challenges. Traditional refrigerators, which rely on low temperatures to delay spoilage, are no longer sufficient to meet consumers' demands for refined preservation indicators such as the moisture content of fruits and vegetables and the firmness of leafy greens. When the humidity inside the refrigerator compartment drops below 70%, leafy green vegetables can lose up to 15% of their moisture within 24 hours, and berries like strawberries experience a three-fold increase in skin wrinkling. This not only accelerates the loss of nutrients but also affects the taste and commercial value of the food. Especially in scenarios where frequent opening and closing of the refrigerator door causes drastic humidity fluctuations, traditional humidity control technologies often suffer from slow response times and slow humidity recovery, making it difficult to maintain a stable humidity environment.

[0035] In related technologies, increasing the humidity of the storage environment improves the preservation effect of food. Ultrasonic atomization humidification technology has advantages such as rapid humidification and low energy consumption and low cost, and is therefore applied to refrigerators due to its unique advantages.

[0036] In existing technologies, ultrasonic atomizing devices are mostly installed inside the door or cabinet. These devices are mounted in a pre-set position using methods such as threaded connections or magnetic fixation to ensure the stability of the water storage structure during refrigerator door opening and closing, and during transport bumps. However, while threaded connections secure the water storage box to the housing cavity with screws, providing a stable structure, disassembly requires tools and is cumbersome. Magnetic fixation uses magnetic attraction to position the water storage box, offering convenient disassembly, but the attraction force is easily affected by vibration, potentially leading to loosening and displacement after prolonged use.

[0037] To address the aforementioned technical problems, this application proposes a refrigerator, as detailed below with reference to the appendix. Figures 1-10 The refrigerator provided in this application will be described in conjunction with specific embodiments.

[0038] This application provides a refrigerator, as shown in the embodiments of the present application. Figure 1 Figure 10 The refrigerator includes a cabinet 100 having a receiving cavity 101, a door 200 connected to the cabinet 100 for opening and closing the receiving cavity 101, and a refrigeration unit for supplying cold air to the receiving cavity 101. The cabinet 100 includes an inner liner defining the receiving cavity 101, an outer shell connected to the outside of the inner liner to form the appearance of the refrigerator, and a heat insulation layer disposed between the inner liner and the outer shell to insulate the receiving cavity 101. The refrigeration system may include a compressor, a condenser, a throttling device, and an evaporator connected in a cycle.

[0039] During refrigeration system operation, the compressor compresses refrigerant vapor, generating high-temperature, high-pressure refrigerant vapor, and delivers it to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then delivered to the throttling device. The throttling device reduces the pressure of the refrigerant liquid, transforming it from a high-pressure, low-temperature liquid into a low-pressure, low-temperature liquid, which is then delivered to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside the refrigerated room.

[0040] In some embodiments, see Figure 1 The direction from the bottom wall to the top wall of the enclosure 100 is the height direction. The enclosure 100 may have a front wall and a rear wall arranged opposite each other. The side of the enclosure 100 facing the user may be the front wall of the main body. The direction in which the line of intersection of the top wall and the rear wall of the enclosure 100 extends is the width direction.

[0041] In this embodiment, the cabinet 100 may define a plurality of receiving cavities 101. The front end of each receiving cavity 101 has a retrieval opening for placing or removing items, allowing the user to place food into or remove food from the receiving cavity 101 through this opening. A rotatable door 200 is provided on the cabinet 100 to open or close the retrieval opening of the receiving cavity 101. For example, the door 200 is rotatably connected to the cabinet 100 by hinge assemblies located at the upper and lower parts of the refrigerator.

[0042] In some embodiments of this application, the plurality of receiving cavities 101 may include a refrigerator compartment and a freezer compartment. The refrigerator compartment and the freezer compartment are distributed along the width direction of the refrigerator. The refrigerator compartment extends along the height direction of the cabinet 100. The freezer compartment extends along the height direction of the cabinet 100.

[0043] In some embodiments of this application, reference is made to Figure 1 The refrigerator body 100 can be equipped with four doors 200. Two of the four doors 200 are refrigerator doors, and the other two are freezer doors. The refrigerator doors are used to open or close the refrigerator compartment, and the freezer doors are used to open or close the freezer compartment. When the refrigerator door and the freezer door are closed simultaneously, the front wall of the refrigerator door and the front wall of the freezer door together form the front wall of the refrigerator.

[0044] In some embodiments of this application, a door seal is provided on the side wall of the door 200 near the housing 100. The door seal surrounds the access opening. When the door 200 is closed, the door seal adheres to the front face of the housing 100 to effectively seal the connection between the door 200 and the housing 100, thereby ensuring that the door 200 seals the access opening and preventing cold air from escaping.

[0045] In some embodiments, refer to Figure 1 and Figure 2The refrigerator may include a humidifier 300. The humidifier 300 is used to humidify the receiving cavity 101. The humidifier 300 can be installed on the cabinet 100 or the door 200. Specifically, the humidifier 300 is installed on the door 200 and is used to humidify the refrigerator compartment.

[0046] In some embodiments of this application, reference is made to Figure 2 and Figure 3 The humidifier 300 includes a housing 310, within which a mounting cavity 311 is constructed. The mounting cavity 311 may be located at the front of the housing 310. A mounting opening may be formed on the front side of the mounting cavity 311. A shelf may be provided on the side of the door 200 facing the receiving cavity 101, and the housing 310 may be placed on the shelf.

[0047] In some embodiments of this application, reference is made to Figure 2 , Figure 8 and Figure 9 The humidifier 300 also includes a water storage box 320 for storing water. The water storage box 320 is disposed within the mounting cavity 311 and is removably mounted within the mounting cavity 311 via a mounting opening, facilitating its removal from the mounting cavity 311. When it is necessary to remove the water storage box 320 from the mounting cavity 311 for refilling, it can be simply pulled out, which is convenient and quick. The water storage box 320 forms a water storage cavity 321 and a spray nozzle 322; the spray nozzle 322 is configured to spray water mist towards the receiving cavity for humidifying and preserving the stone within the receiving cavity 101.

[0048] In some embodiments of this application, reference is made to Figures 3-7 The humidifier 300 may also include a locking mechanism 330, which is used to fix the water storage box 320 to the housing 310 when the water storage box 320 is pushed into the installation cavity 311 from the installation port, so as to prevent the refrigerator door 200 from rotating and the vibration generated by the operation of the equipment, and to prevent the water storage box 320 from shifting, loosening or leaking.

[0049] In some embodiments of this application, reference is made to Figures 3-10 The locking mechanism 330 includes two hooks 331, which can be symmetrically arranged. A first bending portion 3311 is provided at the end of the hook 331 near the spray nozzle 322. The bending directions of the two first bending portions 3311 are opposite to each other. The hook 331 is rotatably connected to the inner wall of the mounting cavity 331.

[0050] It is understandable that the first bending part 3311 refers to the bending structure at the end of the hook 331. It can adopt a bending design with a preset angle, such as a 90-degree bend. Its main purpose is to be able to engage with the buckle 334 on the water storage box 320 when the water storage box 320 is inserted into the installation cavity 311.

[0051] In some embodiments of this application, reference is made to Figures 3-10 The locking mechanism 330 may also include a spring element. The spring element 330 is used to connect the ends of the two hooks 331 away from the spray nozzle 322.

[0052] It should be noted that the elastic element 332 can be an elastic component connecting the ends of the two hooks 331 away from the spray nozzle 322. Specifically, it can be a structure with elasticity, such as a coil spring or an elastic band. For example, a metal spring can be used to provide the restoring force, mainly to automatically reset the hooks 331 after rotation. For example, a fixing post is provided on the side of the two hooks 331 facing the housing 310, and the two ends of the coil spring are respectively hung on the corresponding fixing post.

[0053] For example, refer to Figure 5 and Figure 7 The locking mechanism 330 also includes two fixed shafts 333, which are disposed on the inner wall of the mounting cavity 311. A hook 331 rotates around one of the fixed shafts 333, which is located between the elastic member 332 and the first bent portion 3311. The fixed shaft 333 can be a cylindrical pin or a protruding structure, for example, by injection molding onto the housing 310, providing a pivot point for the hook 331 to rotate.

[0054] In some embodiments of this application, reference is made to Figure 10 The locking mechanism 330 also includes a buckle 334 disposed on the lower surface of the water storage box 320 for active contact with the first bent portion 3311.

[0055] There are two buckles 334. The buckle 334 is a protruding structure on the lower surface of the water storage box 320. Its shape adopts a bent structure bent at a preset angle, and the bending directions of the two buckles 334 are opposite, such as a 90-degree bend. Its main purpose is to be able to form a snap-fit ​​with the first bent part 3311 when the water storage box 320 is inserted into the installation cavity 311.

[0056] In some embodiments of this application, reference is made to Figure 5 and Figure 7The locking mechanism 330 also includes a pull rod 336. A baffle 3364 is provided at the end of the pull rod 336 away from the spray nozzle 322. The end of the hook 331 away from the spray nozzle 322 abuts against the baffle 3364. When the pull rod moves toward the spray nozzle 322, it drives the baffle 3364 to push the hook 331, so that the hook 331 rotates in the mounting cavity 311. At the same time, the two first bends 3311 move toward each other and disengage from the buckle 334.

[0057] Furthermore, a sliding hole 312 can be provided on the housing 310, and a limiting post 335 is provided on the side of the pull rod 336 away from the water storage box 320. The limiting post 335 extends out of the sliding hole 312 and is located outside the housing 310.

[0058] When the water storage box 320 is inserted into the mounting cavity 311, the first bent part 3311 engages with the buckle 334 to form a mechanical lock, ensuring a smooth locking process and enhanced vibration resistance. At the same time, the elastic element 332 provides a stable elastic restoring force, keeping the hook 331 locked. This ensures that the hook 331 maintains reliable contact with the buckle 334 during refrigerator door opening and closing or transportation bumps, preventing accidental detachment and ensuring that the water storage box 320 is stable, does not loosen, and does not leak when the equipment is running or the door 200 is rotating. When the water storage box 320 needs to be removed from the mounting cavity 311, the user can push the limiting post 335 so that the limiting post 335 slides in the sliding hole 312 toward the side closer to the spray nozzle 322, thereby driving the push rod to move, which in turn causes the baffle 3364 to push the hook 331. The hook 331 is driven to rotate around the fixed shaft 333, which causes the two first bending parts 3311 to move toward each other and disengage from the buckle 334, thereby releasing the water storage box 320, realizing the stable fixation and quick disassembly of the water storage box 320.

[0059] In some embodiments of this application, reference is made to Figure 4 and Figure 7 The two hooks 331 are further provided with a second bending portion 3312 at the end away from the spray nozzle 322, and the bending directions of the two second bending portions 3312 are opposite to each other; the baffles 3364 of the pull rod 336 respectively abut against the side of the two second bending portions 3312 away from the spray nozzle 322. It can be understood that the bending angle of the second bending portion 3312 can be set to 90° to ensure that the contact surface with the baffle 3364 of the pull rod 336 is in a flat fit; the pull rod 336 is provided with two baffles 3364, one baffle 3364 corresponds to one second bending portion 3312, and the contact surface between the baffle 3364 and the second bending portion 3312 is provided with anti-slip texture or rubber layer to increase the friction during the transmission process and avoid relative sliding.

[0060] When the user pushes the limiting post 335 with their finger, the baffle 3364 smoothly applies a pushing force to the second bending part 3312. The hook 331 rotates smoothly around the fixed shaft 333, and the first bending part 3311 retracts inward to disengage from the buckle 334, allowing the water storage box 320 to be removed from the mounting cavity 311. This technical solution effectively avoids stress concentration caused by the baffle 3364 directly acting on the end of the hook 331, significantly reducing the wear risk of the hook 331 during repeated unlocking operations. Furthermore, the opposing bending structure of the two second bending parts 3312 prevents interference between the pull rod 336 and the hook 331 during transmission, ensuring that each unlocking action accurately and smoothly drives the hook 331 to disengage from the buckle 334.

[0061] In some embodiments of this application, reference is made to Figure 4 and Figure 5 The pull rod 336 includes a first sliding rod 3361, a second sliding rod 3362, and a connecting rod 3363. The first sliding rod 3361 engages with one of the second bends 3312, and a baffle 3364 is located at the end of the first sliding rod 3361 furthest from the spray nozzle 322. The second sliding rod 3362 engages with the other second bend 3312, and a baffle 3364 is located at the end of the second sliding rod 3362 furthest from the spray nozzle 322. The connecting rod 3363 connects the first sliding rod 3361 and the second sliding rod 3362, and a limiting post 335 is located on the side of the connecting rod 3363 facing away from the water storage box 320.

[0062] The pull rod 336 can be integrally injection molded with the first sliding rod 3361, the second sliding rod 3362, and the connecting rod 3363, or it can be a separate structure connected by welding or bonding. The first sliding rod 3361 and the second sliding rod 3362 are symmetrically distributed on both sides of the connecting rod 3363, with their axes parallel and aligned with the direction of the push-in mounting cavity 311 of the water storage box 320. The end of the first sliding rod 3361 away from the connecting rod 3363 is vertically bent to form a baffle 3364. This baffle 3364 has surface contact with the side of one of the second bends 3312 away from the spray nozzle 322. Similarly, the end of the second sliding rod 3362 away from the connecting rod 3363 is also provided with a baffle 3364, achieving precise contact with the other second bend 3312.

[0063] When the user pushes the limiting post 335 toward the spray nozzle 322, the connecting rod 3363 simultaneously drives the first sliding rod 3361 and the second sliding rod 3362 on both sides to slide in a direction along the first sliding groove 313 and the second sliding groove 314 on the housing 310, thereby driving the two baffles 3364 to simultaneously apply an axial thrust toward the spray nozzle 322 to the corresponding second bending part 3312. Since the second bending part 3312 and the main body of the hook 331 are at a fixed angle, the axial thrust can be converted into a torque that drives the hook 331 to rotate around the fixed axis 333 through force decomposition. The symmetrical layout of the first sliding rod 3361 and the second sliding rod 3362 and the rigid connection with the connecting rod 3363 ensure that the torque on the hooks 331 on both sides is completely consistent, achieving synchronous and unidirectional rotation, so that the two first bending parts 3311 move precisely toward each other and disengage from the buckle 334.

[0064] In some embodiments of this application, reference is made to Figure 4 and Figure 5 The inner surface of the housing 310 is provided with a first sliding groove 313 and a second sliding groove 314. The first sliding groove 313 is used to install the first sliding rod 3361, and the second sliding groove 314 is used to install the second sliding rod 3362. The first sliding groove 313 and the second sliding groove 314 are provided on the inner surface of the housing 310 corresponding to the first sliding rod 3361 and the second sliding rod 3362. The sliding grooves provide directional guidance for the sliding rods, ensuring that the first and second sliding rods 3362 can slide smoothly along a fixed trajectory, avoiding deviation or jamming. This ensures that the force exerted by the baffle 3364 on the second bending part 3312 is always accurately transmitted, driving the two hooks 331 to rotate synchronously and smoothly, ensuring a smooth and reliable unlocking action.

[0065] In one specific embodiment, refer to Figure 4 and Figure 5 Four support plates 317 forming a rectangle are provided on the inner surface of the housing 310. A first sliding groove 313 and a second sliding groove 314 are located within the area enclosed by the support plates 317. A first sliding rod 3361 is installed in the first sliding groove 313, and a second sliding rod 3362 is installed in the second sliding groove 314. The thickness of the first sliding rod 3361 is equal to the depth of the first sliding groove 313, and the thickness of the second sliding rod 3362 is equal to the depth of the second sliding groove 314. Two hooks 331 are placed on the upper surfaces of the first sliding rod 3361 and the second sliding rod 3362, and the sum of the thickness of the hooks 331 and the thickness of the first sliding rod 3361 is equal to the height of the support plates 317.

[0066] This setup utilizes four rectangular support plates 317 to create an independent and regular installation reference area, providing a stable bearing foundation for the first and second sliding grooves 314. This prevents deformation of the sliding grooves due to long-term stress or vibration, ensuring consistently reliable guiding accuracy. Simultaneously, the design of the first sliding rod 3361 having a thickness equal to the depth of the first sliding groove 313, and the second sliding rod 3362 having a thickness equal to the depth of the second sliding groove 314, ensures that the upper surface of the sliding rod is flush with the groove opening after being embedded, forming a flat support surface. This, combined with the two hooks... 331 is placed on the upper surface of the sliding rod, and the sum of the thickness of the hook 331 and the thickness of the sliding rod is exactly equal to the height of the support plate 317, which realizes the precise vertical positioning of the hook 331. The height constraint of the support plate 317 prevents the hook 331 from moving up and down. The equal thickness matching of the sliding groove and the sliding rod avoids the horizontal offset of the hook 331, so that the hook 331 is always in the preset installation position, ensuring that its trajectory is accurate when rotating around the fixed axis 333. The alignment accuracy of the first bending part 3311 and the buckle 334 of the water storage box 320 is greatly improved.

[0067] In some embodiments of this application, reference is made to Figure 4 and Figure 5 A first stop 315 is provided on the side of the first sliding groove 313 near the second sliding groove 314. The first stop 315 is fixedly installed on the inner surface of the housing 310. The first stop 315 is located on the side of the second bending portion 3312 away from the spray nozzle 322. The first stop 315 is used to limit one of the second bending portions 3312.

[0068] The first stop 315 is fixed to the inner surface of the housing 310 and located within the area enclosed by the support plate 317, and is arranged perpendicularly to the groove wall of the first sliding groove 313. The side of the first stop 315 facing the second bending portion 3312 is a vertical limiting surface, ensuring that the contact with the second bending portion 3312 is a surface contact, avoiding local stress concentration. The height of the first stop 315 is consistent with the height of the support plate 317, and its top is flush with the upper surface of the hook 331, so as not to interfere with the installation and locking of the water storage box 320.

[0069] When the locking mechanism 330 is in the locked state, the second bent part 3312 and the limiting surface of the first stop part 315 are closely fitted to ensure that the first bent part 3311 of the hook 331 and the buckle 334 of the water storage box 320 maintain a preset engagement depth, which avoids the engagement being too shallow and thus not locking properly, and also prevents the engagement being too deep and thus affecting the smoothness of subsequent unlocking.

[0070] By limiting the second bending part 3312 on the corresponding side through the first stop part 315, the force on the hook 331 in the locked state can be distributed, reducing the continuous contact force between the second bending part 3312 and the baffle 3364, reducing component wear. With the guiding effect of the sliding groove, the locking and unlocking action of the hook 331 is always kept within the preset trajectory, which not only ensures the stability of the water storage box 320 during long-term use, but also makes the operation always smooth and effortless. It further adapts to the usage scenario of frequent opening and closing and vibration of the refrigerator door 200, and enhances the overall reliability of the mechanism.

[0071] In some embodiments of this application, reference is made to Figure 4 and Figure 5 A second stop 316 is also provided on the side of the second sliding groove 314 near the first sliding groove 313. The second stop 316 is fixedly installed on the inner surface of the housing 310. The second stop 316 is located on the side of the second bending part 3312 away from the spray nozzle 322. The second stop 316 is used to limit the second bending part 3312.

[0072] The second stop 316 is fixed to the inner surface of the housing 310 and located within the area enclosed by the support plate 317, and is arranged perpendicularly to the groove wall of the second sliding groove 314. The side of the second stop 316 facing the second bending portion 3312 is a vertical limiting surface, ensuring that the contact with the second bending portion 3312 is a surface contact, avoiding local stress concentration. The height of the second stop 316 is consistent with the height of the support plate 317, and its top is flush with the upper surface of the hook 331, so as not to interfere with the installation and locking of the water storage box 320.

[0073] A second stop 316 is added to the side of the second sliding groove 314 near the first sliding groove 313 and fixed to the inner surface of the housing 310. This stop is specifically designed to limit the second bending part 3312 on the corresponding side. This can disperse the force on the hook 331 in the locked state, reduce the continuous contact force between the second bending part 3312 and the baffle 3364, reduce component wear, and, together with the guiding effect of the sliding groove, ensure that the locking and unlocking actions of the hook 331 are always kept within the preset trajectory. This not only ensures the stability of the water storage box 320 during long-term use, but also makes the operation always smooth and effortless. This further adapts to the frequent opening and closing and vibration of the refrigerator door 200 and enhances the overall reliability of the mechanism.

[0074] In some embodiments of this application, reference is made to Figure 8 and Figure 9 The water storage box 320 also has an atomizing chamber 323, which is connected to the spray nozzle 322. At least one atomizing element 326 is provided in the atomizing chamber 323, which is used to convert the water in the water storage chamber 321 into water mist and then spray it out from the spray nozzle 322.

[0075] In one specific embodiment, two atomizing chambers 323 are provided. The two atomizing chambers 323 are symmetrically arranged and are both located on the side of the water storage chamber 321 near the spray nozzle 322. Part of the water storage chamber 321 is located between the two atomizing chambers 323, and the other part is located on the side of the two atomizing chambers 323 away from the spray nozzle 322. That is, the water storage box 320 has two symmetrically arranged atomizing chambers 323 inside corresponding to the position of the spray nozzle 322. Both atomizing chambers 323 are located on the side of the water storage chamber 321 near the spray nozzle 322. Part of the water storage chamber 321 is embedded between the two atomizing chambers 323 to form an intermediate water storage area, and the other part extends to the side of the two atomizing chambers 323 away from the spray nozzle 322 to form a main water storage area. The intermediate water storage area and the main water storage area are interconnected to ensure water circulation and supply.

[0076] In addition, refer to Figure 8 A power unit is also provided between the water storage box 320 and the housing 310 to provide power to the atomizing element 326. The output end of the power unit is set on the side wall of the water storage box 320 through a spring. A first cover plate 325 is provided on the water storage cavity 321 to seal the water storage cavity. A wiring groove 3251 is provided on the side of the first cover plate 325 away from the water storage cavity 321. Multiple wirings are provided in the wiring groove 3251. One end of the multiple wirings is electrically connected to the spring of the power unit, and the other end of the wirings is electrically connected to the atomizing element 326 or the lighting element 337 respectively.

[0077] The atomizing element 326 can be an ultrasonic atomizer. The ultrasonic atomizer is installed on the side wall of the atomizing chamber 323 away from the spray nozzle 322 by means of mounting base or screw locking. The ultrasonic atomizer is connected to the water storage chamber 321 to ensure that the water in the water storage chamber 321 can flow into the atomizer continuously and stably. The ultrasonic atomizer is set towards the spray nozzle 322.

[0078] In addition, a water inlet is provided on the upper surface of the first cover plate 325, through which water can be injected into the humidifying water box. The water inlet is connected to the water storage chamber 321. The water inlet is sealed by a water injection piston 327.

[0079] A separate atomizing chamber 323 is constructed within the water storage box 320, housing at least one atomizing element 326. This achieves an integrated layout of the atomizing structure while ensuring both humidification effect and reliability. The atomizing chamber 323 provides an independent and stable installation space for the atomizing element 326, preventing it from shaking or shifting during disassembly and transportation of the water storage box 320. Simultaneously, it isolates the atomizing element 326 from the direct impact of water within the water storage chamber 321, extending its service life.

[0080] In some embodiments of this application, reference is made to Figure 8The water storage box 320 has two symmetrically arranged atomizing chambers 323 inside, corresponding to the spray nozzle 322. Both atomizing chambers 323 are located on the side of the water storage chamber 321 near the spray nozzle 322. A part of the water storage chamber 321 is embedded between the two atomizing chambers 323 to form an intermediate water storage area, and the other part extends to the side of the two atomizing chambers 323 away from the spray nozzle 322 to form a main water storage area. The intermediate water storage area and the main water storage area are interconnected to ensure water circulation supply. Each atomizing chamber 323 is fixedly installed with an ultrasonic atomizer. The ultrasonic atomizer is fixed to the side wall of the atomizing chamber 323 away from the spray nozzle 322 by a buckle 334. The ultrasonic atomizer faces the spray nozzle 322. When working, it atomizes the water in the water storage chamber 321 into micron-sized water mist. Under the action of air pressure, the water mist is directionally sprayed into the receiving cavity 101 through the spray nozzle 322 to achieve humidity regulation.

[0081] To facilitate users' real-time monitoring of the water level and water quality in the water storage chamber 321, an observation hole 324 is provided on the side of the middle water storage area of ​​the water storage box 320. The observation hole 324 has a circular, elliptical, or rectangular structure and is directly connected to the interior of the water storage chamber 321. The inner wall of the observation hole 324 has a stepped mounting groove. The viewing plate is fixed in the mounting groove by snapping or bonding. The viewing plate can be made of high-transmittance PC material with an anti-fog coating on the surface, which not only ensures the sealing of the water storage chamber 321 but also allows for clear observation of the remaining water level and water cleanliness, avoiding the impact of turbid water or low water level on the humidification effect.

[0082] An observation hole 324 communicating with the water storage chamber 321 is provided on the water storage box 320 and a transparent plate is embedded therein. The transparent plate not only ensures the sealing of the water storage chamber 321 to prevent water leakage, but also allows users to directly observe the remaining water level and water quality through the observation hole 324 without disassembling the water storage box 320. Users can decide whether to add water or clean according to the observation results, avoiding blind disassembly and simplifying the operation process.

[0083] In some embodiments of this application, reference is made to Figure 8 The humidification device 300 also includes an illumination element 337; the illumination element 337 is disposed in the water storage cavity 321 and fixed to the upper cavity wall of the water storage cavity 321. Specifically, the illumination element 337 is located on the top wall of the water storage cavity 321 between the two atomizing cavities 323.

[0084] By adding a lighting element 337 fixed to the upper cavity wall inside the water storage cavity 321, the inside of the water storage cavity 321 can be illuminated directly, making it convenient for users to quickly observe the remaining water level. Users can determine whether water needs to be added without disassembling the water storage box 320. Combined with the quick unlocking structure of the water storage box 320, the water replenishment operation process is further simplified.

[0085] In some embodiments of this application, reference is made to Figure 2 and Figure 10 The extension direction of the spray nozzle 322 is the same as the length direction of the water storage box 320. The spray nozzle 322 is an opening structure for directional spraying of water mist, and it can be implemented with different cross-sectional shapes such as circular, elliptical, or slit-shaped. Its purpose is to controllably deliver the atomized water mist into the receiving cavity 101. Since there are two atomizing cavities 323, there are also two spray nozzles 322, and the spray nozzles 322 are connected to the atomizing cavities 323.

[0086] As a specific implementation, the water storage box 320 can be specifically designed as a long strip structure, with its length extending along the width direction of the door 200; the spray nozzle 322 can be specifically set as a slit-like opening extending along the length direction of the water storage box 320, so that the water mist is uniformly sprayed into the receiving cavity 101 in a linear manner.

[0087] By setting the extension direction of the spray nozzle 322 to be the same as the length direction of the water storage box 320, the water mist can be spread evenly across the entire width of the cavity, avoiding the problem of local humidity imbalance caused by random spray direction. This can significantly improve the humidification uniformity and coverage of the refrigerator cavity 101, and make the atomized water mist diffuse linearly along the length direction of the water storage box 320. This can be adapted to the installation space layout of the refrigerator door 200, allowing the water mist to more comprehensively cover the horizontal area of ​​the cavity 101 and avoid the problem of uneven local humidification.

[0088] A refrigerator is also disclosed in a second aspect of the embodiments of this application, with reference to Figure 1 and Figure 8 , Figure 9 The device includes a housing 100 and a door 200. The housing 100 is divided into multiple independent compartments 101 by partitions for storing different ingredients. The door 200 is rotatably mounted on the housing 100 to close or open the compartments 101. The door 200 is rotatably connected to one side of the housing 100 via a hinge assembly. When closed, the door 200 fits against the sealing surface of the housing 100, achieving sealed insulation of the compartments 101. When open, the door 200 allows easy access to the compartments 101 for food storage. Furthermore, a humidifier 300 is installed on the door 200 to humidify the compartments 101. A shelf is provided on the inner wall of the door 200, and the humidifier 300 is placed within the shelf. Its installation height corresponds to the central area of ​​the compartments 101, ensuring that water mist can be evenly distributed to all corners of the compartments 101.

[0089] The humidifier 300 includes a housing 310 and a water storage box 320. An installation cavity 311 is constructed within the housing 310, with its opening facing outwards from the door 200 to facilitate the installation and removal of the water storage box 320. The water storage box 320 is disposed within the installation cavity 311, and its interior forms a water storage chamber 321 for storing humidifying water. An elongated spray nozzle 322 is constructed on the front end face of the water storage box 320, extending in the same direction as the length of the water storage box 320. The spray nozzle 322 is positioned facing the refrigerator's receiving cavity 101, ensuring that the atomized water mist can be directionally sprayed into the receiving cavity 101.

[0090] In another embodiment, the humidifying device 300 may also include a locking mechanism (not shown in the figure), which is used to fix the water storage box 320 to the housing 310 when the water storage box 320 is pushed into the mounting cavity 311 from the mounting port, so as to prevent the refrigerator door 200 from rotating and the vibration generated by the operation of the equipment, and to prevent the water storage box 320 from shifting, loosening or leaking.

[0091] The locking mechanism includes two hooks, a spring element, and a pull rod. The two hooks can be symmetrically arranged. A first bend is provided at the end of each hook near the spray nozzle, with the two bends bending in opposite directions. The hooks are rotatably connected to the bottom wall of the water storage box 320. The spring element connects the ends of the two hooks away from the spray nozzle 322. Two latches are provided within the mounting cavity, which are used to make movable contact with the first bends. A baffle is provided at the end of the pull rod away from the spray nozzle 322. The ends of the hooks away from the spray nozzle 322 abut against the baffle. When the pull rod moves towards the spray nozzle 322, it drives the baffle to push the hooks, causing the hooks to rotate relative to the water storage box 320. Simultaneously, the two first bends move towards each other, thus disengaging from the latches.

[0092] Furthermore, a sliding groove can be provided on the housing 310. When the water storage box 320 is located in the mounting cavity 311, the pull rod is located in the sliding groove. When the water storage box 320 is inserted into the mounting cavity 311, the first bent part engages with the buckle to form a mechanical lock, ensuring a smooth locking process and enhanced vibration resistance. At the same time, a stable elastic restoring force is provided by the elastic element to keep the hook in a locked state, ensuring that the hook maintains reliable contact with the buckle during refrigerator door opening and closing or transportation bumps, preventing accidental dislodgement, and ensuring that the water storage box 320 is stable, does not loosen, and does not leak when the equipment is running or the door 200 is rotating. When the water storage box 320 needs to be removed from the mounting cavity 311, the user can push the pull rod, causing it to slide in the sliding groove towards the side near the spray nozzle 322. This drives the push rod to move, which in turn causes the baffle to push the hook. The hook is driven to rotate relative to the water storage box 320, which in turn causes the two first bends to move towards each other and disengage from the latch, thereby releasing the water storage box 320. This achieves both secure fixing and quick disassembly of the water storage box 320. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it.
