[0004] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a consumer product that keeps food or other items at a constant low temperature. In related technologies, refrigerator doors are equipped with ice-making devices to produce ice and meet users' needs for ice. Door-mounted ice-making systems require door air ducts designed into the door. When the door is closed, the door air duct connects with the cabinet air duct, delivering cold air from the cabinet to the ice-making system to provide a cold source. A seal is required at the air supply connection point between the door and the cabinet to seal the corresponding interface between the cabinet and door air ducts when the door is closed. However, in related technologies, the seals at the air duct connection points are often ineffective, leaving gaps that affect the transfer of cold air to the door-mounted ice-making system, leading to reduced system efficiency.

[0041] To make the objectives, implementation methods, and advantages of this application clearer, some exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of some exemplary embodiments. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments. It should be noted that the brief descriptions of terms in some embodiments of this application are only for the convenience of understanding the implementation methods described below, and are not intended to limit the implementation methods of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0042] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a consumer product that keeps food or other items at a constant low temperature. In related technologies, refrigerator doors are equipped with ice-making devices to produce ice and meet users' needs for ice. Door-mounted ice-making systems require door air ducts designed into the door. When the door is closed, the door air duct connects with the cabinet air duct, delivering cold air from the cabinet to the ice-making system to provide a cold source. A seal is required at the air supply connection point between the door and the cabinet to seal the corresponding interface between the cabinet and door air ducts when the door is closed. However, in related technologies, the seals at the air duct connection points are often ineffective, leaving gaps that affect the transfer of cold air to the door-mounted ice-making system, leading to reduced system efficiency.

[0043] Figure 1 is a structural schematic diagram of a refrigerator provided in some embodiments of this application. Figure 2 is a structural schematic diagram of the cooperation between the air duct opening in the refrigerator body and the air duct opening in the door shown in Figure 1. As shown in Figures 1 and 2, the refrigerator 100 provided in some embodiments of this application includes a cabinet 10 and a door 20. The cabinet 10 has a storage compartment 11. The storage compartment 11 is used by the user to place food that needs to be refrigerated. The door 20 is rotatably mounted on the cabinet 10 and is used to close the opening of the storage compartment 11. In some embodiments of this application, the cabinet 10 has an inner liner, and the storage compartment 11 is formed inside the inner liner. The cabinet 10 is provided with a cold air passage. The cold air passage is used to provide cooling capacity to the refrigerator 100.

[0044] The refrigerator 100 provided in some embodiments of this application also includes an ice-making device. The ice-making device is disposed on the door 20. The inner wall of the storage compartment 11 is provided with a cabinet air duct 12. The cabinet air duct 12 communicates with the cold air passage. The door 20 is provided with a door air duct 21 at a position opposite to the cabinet air duct 12. The ice-making device communicates with the door air duct 21. When the door 20 closes the opening of the storage compartment 11, the cabinet air duct 12 and the door air duct 21 are connected, so that the cold air in the cold air passage in the cabinet 10 enters the door 20 through the cabinet air duct 12 and the door air duct 21, providing cooling capacity for the ice-making device, thereby facilitating ice making. In some embodiments of this application, the door 20 is provided with a door liner, the interior of which forms a space to accommodate the ice-making device, and the door air duct 21 is disposed on the door liner. In some embodiments of this application, the cabinet air duct 12 includes a cabinet air inlet 121 and a cabinet air return duct 122. The door air duct 21 includes a door air inlet 211 and a door air return duct 212. These ducts together constitute an ice-making air duct dedicated to the ice-making device. This ice-making air duct includes an air inlet duct and a air return duct, and its function is to blow cold air from the evaporator cavity to the ice-making device through the air inlet duct, and then send the heat-exchanged air back to the evaporator cavity through the air return duct, forming an independent refrigeration cycle. As shown in Figure 2, when the door 20 is open, the ice-making air duct is in the open state, and both the cabinet air duct 12 and the door air duct 21 are exposed. When the door 20 closes the storage chamber 11, the air inlet 121 of the cabinet connects with the air inlet 211 of the door to form a complete ice-making air intake duct, allowing cold air to be blown onto the door 20 for heat absorption. Simultaneously, the air return vent 122 of the cabinet connects with the air return vent 212 of the door to form a complete ice-making air return duct, allowing hot air to return. As shown in Figure 8, the air inlet 211 and the air return vent 212 of the door are arranged vertically along the height of the door 20. It should be particularly noted that in some embodiments of this application, the low-temperature environment (e.g., -18°C) of the ice-making device and its dedicated air duct differs significantly from the refrigerated environment (e.g., 4°C) of the storage chamber 11 inside the cabinet. Therefore, it is important to form an effective airtight and heat-sealing barrier at the connection point between the air duct vent 12 of the cabinet and the air duct vent 21 of the door. When the door 20 is closed, the low-temperature ice-making circulation duct is effectively isolated from the relatively high-temperature and high-humidity environment of the storage compartment 11 at the air vent connection point. This prevents hot air and moisture in the storage compartment 11 from leaking into the ice-making duct, avoiding temperature cross-contamination. This solves a series of problems such as decreased ice-making efficiency, increased overall refrigerator energy consumption, and frost buildup and blockage at the air vent connection point due to moisture condensation, ensuring the efficient and stable operation of the entire door-mounted ice-making system.

[0045] The refrigerator 100 provided in some embodiments of this application also includes a sealing device 30. The sealing device 30 is disposed at at least one of the cabinet air duct opening 12 and the door air duct opening 21. That is, when there is only one sealing device 30, it can be disposed at one of the cabinet air duct opening 12 and the door air duct opening 21; while when there are multiple sealing devices 30, they can be disposed at one of the cabinet air duct opening 12 and the door air duct opening 21, or some of the multiple sealing devices 30 can be disposed at the cabinet air duct opening 12 and others at the door air duct opening 21. The sealing device 30 is used to seal the mating position between the cabinet air duct opening 12 and the door air duct opening 21. In some embodiments of this application, the sealing device 30 is disposed at the cabinet air inlet 121, the cabinet air return vent 122, the door air inlet 211, and the door air return vent 212, thereby sealing all air duct openings and improving the sealing effect. However, this is not the only embodiment. In some embodiments, the sealing device 30 may also be provided at the air inlet 121 and the air outlet 122 of the enclosure, or at the air inlet 211 and the air outlet 212 of the door, or at the air inlet 121 and the air outlet 212 of the door, or at the air inlet 211 and the air outlet 122 of the door, thereby sealing the docking position of the air inlet 121 of the enclosure and the air inlet 211 of the door, and the docking position of the air outlet 122 of the enclosure and the air outlet 212 of the door.

[0046] Figure 3 is a partially disassembled structural diagram of the refrigerator door shown in Figure 1. As shown in Figure 3, the sealing device 30 includes a fixing ring 31 and a sealing ring 32. The fixing ring 31 can be made of rigid plastic or other materials, and its function is to provide structural support and be reliably fixed to the cabinet or door. The sealing ring 32 is made of a soft sealing material (i.e., an elastic material), such as rubber or silicone rubber, and is used to undergo elastic deformation during connection to achieve an airtight seal. The sealing device 30 is provided between the cabinet air duct opening 12 and the door air duct opening 21. The sealing device 30 is fixed to the cabinet air duct opening 12 and the door air duct opening 21 through the connection between the sealing ring 32 and the fixing ring 31. The sealing device 30 can be provided on either the cabinet air duct opening 12 or the door air duct opening 21. In some embodiments of this application, the sealing device 30 is provided on the door air duct opening 21. Manufacturing the structure for mounting the fixing ring 31 on the housing 10 would be difficult in terms of mold making and cost, and might also affect the flatness of the inner liner. In contrast, placing the sealing device 30 on the door 20 is more economical and feasible in terms of process. When the sealing device 30 is placed on the door duct opening 21, firstly, to achieve the sealing function, the sealing ring 32, as the main sealing element, is positioned on the side facing the door duct opening 12, so that it contacts the corresponding plane of the housing 10 when the door 20 is closed and forms a sealing barrier. Secondly, the fixing ring 31, as a supporting component, is correspondingly positioned on the side of the door duct opening 21 away from the housing 10. This position allows for a tighter contact between the fixing ring 31 and the door liner during the foam filling process of the door, effectively utilizing the foaming pressure to firmly fix it, while significantly preventing the foam material from leaking from the area around the duct opening, thereby ensuring unobstructed airflow and the reliability of the overall product quality. Furthermore, the fixing ring 31 can be installed as a separate part, using a snap-fit ​​or inverted structure (as shown in Figure 10) to fit with the door liner, or its structural features (such as a mating groove) can be integrally molded with the door body (e.g., the door liner) according to the specific manufacturing process. As shown in Figure 10, after the sealing ring 32 is connected to the fixing ring 31, multiple airbags 33 are formed between the fixing ring 31 and the sealing ring 32. The multiple airbags 33 are arranged around the opening of the air duct 12 of the housing or the air duct 21 of the door. The multiple airbags 33 structure formed between the sealing ring 32 and the fixing ring 31, and the multiple airbags 33 around the opening of the air duct 12 of the housing or the air duct 21 of the door, can effectively isolate the air duct from the external airflow. The enhanced insulation and sealing support strength of the walls between the airbags of the sealing ring 32 achieve better insulation, thereby improving the sealing performance and reducing cold air leakage. This helps to improve the temperature stability on the door 20, ensuring that the ice-making device can obtain a stable cold airflow, thereby improving the ice-making efficiency and speed.Furthermore, the airbag 22 is arranged around the opening of the air duct, and there is gas in the airbag. Since the heat conduction efficiency of the gas is low, the heat exchange between the door 20 and the box 10 is further reduced, resulting in high heat preservation effect and improved cooling effect on the door 20, thereby improving the efficiency of the ice-making device on the door.

Figure 5 is a schematic diagram of the fixing ring of the sealing device on the door shown in Figure 3 according to some embodiments of this application. Figure 6 is a schematic diagram of the sealing ring of the sealing device on the door shown in Figure 3 according to some embodiments of this application. Figure 7 is a schematic diagram of the sealing ring of the sealing device on the door shown in Figure 3 according to some embodiments of this application. Figure 8 is a schematic diagram of the structure of the door of the refrigerator shown in Figure 1. Figure 9 is a cross-sectional view of the door shown in Figure 8 along AA. Figure 10 is an enlarged schematic diagram of part B of the door shown in Figure 9.

[0048] As shown in Figures 4 and 7, in some embodiments of this application, the fixing ring 31 has a fixing part 311 on the side facing the sealing ring 32. The sealing ring 32 has a mating part 321 on the side facing the fixing ring 31. The fixing part 311 and the mating part 321 engage with each other, thereby fixing the sealing device 30 to the air duct opening 12 of the cabinet and / or the air duct opening 21 of the door. In this way, the engagement of the fixing part 311 and the mating part 321 provides a more secure connection, ensuring that the sealing ring 32 will not easily fall off or shift during use, thus maintaining a long-term stable sealing effect. The engaging structure makes the installation and removal of the sealing ring 32 easier, requiring no complicated tools or processes, making it convenient for users or maintenance personnel to replace and maintain it. At the same time, the engaging design can compensate for errors in the manufacturing and installation process to a certain extent, ensuring a good fit between the sealing ring 32 and the fixing ring 31, further improving the sealing performance, and ensuring the stability of the internal temperature and the improvement of energy efficiency of the refrigerator 100.

[0049] In some embodiments of this application, the fixing part 311 and the mating part 321 are arranged around the opening of the air duct. The fixing part 311 and the mating part 321, arranged around the opening, provide uniform support and fixation, ensuring a consistent pressure distribution of the sealing ring 32 around the entire air duct opening, reducing deformation and displacement of the sealing ring 32, and improving the sealing effect of the sealing ring 32. In some embodiments of this application, one of the fixing part 311 and the mating part 321 is a snap-fit, and the other is an overlock. This snap-fit ​​and overlock combination makes the connection between the sealing ring 32 and the fixing ring 31 more stable, reducing the risk of loosening or falling off. The combination of the overlock and snap-fit ​​makes the installation process more intuitive and simple; usually, only a light press is needed to achieve the snap-fit, and the operation can be completed without the aid of tools, reducing installation time and complexity, and improving user convenience. At the same time, the tight combination of the snap-fit ​​and overlock can effectively resist vibrations caused by the opening and closing of the refrigerator 100 door or other external factors, maintaining the stability of the sealing device 30. Since the engagement of the snap and the buckle requires specific alignment and force, it can also prevent the sealing ring 32 and the fixing ring 31 from being misinstalled or loosened to a certain extent, reducing the chance of errors for users during the installation process.

[0050] Please also refer to Figure 10. In some embodiments of this application, the fixing part 311 is an inverted buckle, and the mating part 321 is a snap-fit. Air duct plates 101 are provided at the openings of the cabinet air duct 12 and the door air duct 21, and the inverted buckle passes through the air duct plate 101. This inverted buckle passing through the air duct plate 101 provides additional support and fixation for the fixing part 311, making the sealing device 30 more stable during use and reducing displacement or loosening caused by external forces. With the support of the air duct plate 101, the combination of the inverted buckle and the snap-fit ​​is tighter, further improving the sealing performance, reducing cold air leakage, and improving the energy efficiency of the refrigerator 100. At the same time, the inverted buckle passing through the air duct plate 101 helps the user more easily align the snap-fit ​​position during installation, simplifying the installation steps and reducing installation errors. In some embodiments of this application, as shown in Figure 10, a mating groove 3111 is provided on the fixing part 311. After the mating part 321 is inserted into the mating groove 3111, it snaps into the fixing part 311.

[0051] Referring also to Figure 5, in some embodiments of this application, the fixing ring 31 further includes an abutment portion 312. The abutment portion 312 is connected to the fixing portion 311 and abuts against the side of the air duct plate 101 opposite to the sealing ring 32. Along the radial direction of the openings of the cabinet air duct 12 and the door air duct 21, the abutment portion 312 is located on the outside of the fixing portion 311. Thus, the abutment portion 312 provides additional support for the fixing ring 31, making the fixing ring 31 more stable under external forces, preventing displacement of the fixing ring 31 and the sealing ring 32 during use, ensuring the continued effectiveness of the sealing device 30, and enhancing the strength and durability of the overall structure. The contact between the abutment portion 312 and the air duct plate 101 provides a stable support surface, ensuring that the sealing ring 32 maintains a good position and shape during use, thereby improving sealing reliability. Simultaneously, the design of the abutment portion 312 helps absorb and disperse vibrations generated by the operation of the refrigerator 100 or the opening and closing of the door, reducing the impact on the sealing device 30 and maintaining its stable performance.

[0052] Please refer to Figures 6 and 10 simultaneously. In some embodiments of this application, the airbag 33 includes an inner ring airbag 331, and the sealing ring 32 also includes an inner flange 322. The inner flange 322 is connected to the mating part 321, and along the radial direction of the openings of the cabinet air duct 12 and the door air duct 21, the inner flange 322 folds inward and abuts against the fixing part 311. The inner ring airbag 331 is formed between the inner flange 322, the mating part 321, and the fixing part 311. Along the radial direction of the openings of the cabinet air duct 12 and the door air duct 21, the inner flange 322 is located inside the mating part 321. In this way, the design of the inner flange 322 makes the connection between the sealing ring 32 and the fixing part 311 more stable, reducing the displacement or deformation of the sealing ring 32 during use. The inner ring airbag 331 can provide a flexible buffer when the refrigerator door 100 is closed, reducing the direct impact on the sealing ring 32 and extending the service life of the sealing ring 32. The flexibility of the inner airbag 331 also reduces noise generated when the refrigerator door closes, providing a quieter operating environment. The design of the inner airbag 331 provides an additional sealing layer, more effectively preventing air and moisture leakage, improving the refrigerator 100's sealing performance and energy efficiency. The design of the inner airbag 331 has the following effects: flexible cushioning and noise reduction: when the refrigerator door closes, this airbag, surrounded by soft material, is compressed, acting as a flexible cushion, reducing rigid impact and thus lowering closing noise, improving the user experience; enhanced sealing: the airbag itself constitutes an additional sealing barrier; even if there are minor imperfections on the main sealing contact surface, this layer of sealed air can effectively prevent cold air leakage and moisture ingress, forming a double layer of protection; extended service life: the cushioning effect reduces direct impact and wear on the sealing ring itself, helping to extend its service life.

[0053] Referring also to Figure 5, in some embodiments of this application, the fixing ring 31 further includes a sealing portion 313. The sealing portion 313 is connected to the side of the fixing portion 311 away from the abutment portion 312. The inner flange 322 abuts against the sealing portion 313, and an inner ring airbag 331 is formed between the sealing portion 313, the inner flange 322, the mating portion 321, and the fixing portion 311. The sealing portion 313 is located inside the fixing portion 311 along the radial direction of the openings of the housing air duct 12 and the door air duct 21. Thus, the sealing portion 313 provides an additional sealing interface for the inner flange 322, further improving the sealing performance of the sealing ring 32 and ensuring more effective prevention of air and moisture leakage. The presence of the sealing portion 313 also improves the pressure resistance of the inner ring airbag 331, making the structure of the inner ring airbag 331 more stable and reducing the deformation of the inner ring airbag 331 under pressure changes, thereby maintaining a consistent sealing effect. In some embodiments of this application, the fixing part 311, the abutting part 312, and the sealing part 313 are all annular, thereby improving the stability of the structure and making the fixing ring 31 more stable when subjected to external force.

[0054] Please refer to Figures 6, 7, and 10 simultaneously. In some embodiments of this application, the airbag 33 includes an outer ring airbag 332. The sealing ring 32 also includes an outwardly turned edge 323. The outwardly turned edge 323 is connected to the mating part 321, and along the radial direction of the openings of the housing air duct 12 and the door air duct 21, the outwardly turned edge 323 folds outward and abuts against the air duct plate 101. The outer ring airbag 332 is formed between the outwardly turned edge 323, the mating part 321, the fixing part 311, and the air duct plate 101. Along the radial direction of the openings of the housing air duct 12 and the door air duct 21, the outwardly turned edge 323 is located on the outside of the mating part 321. In this way, the design of the outwardly turned edge 323 makes the connection between the sealing ring 32 and the air duct plate 101 more stable, reducing the displacement or deformation of the sealing ring 32 during use. When subjected to external force, the outwardly turned edge 323 can better disperse and absorb the impact, reduce wear, and improve the durability of the sealing device 30. The outer airbag 332 better adapts to pressure changes inside and outside the refrigerator 100, providing a flexible buffer when the refrigerator door is closed, reducing direct impact on the sealing ring 32 and extending its service life. The flexibility of the outer airbag 332 also reduces noise generated when the refrigerator door closes, providing a quieter operating environment. The design of the outer airbag 332 provides an additional sealing layer, more effectively preventing air and moisture leakage, improving the sealing performance and energy efficiency of the refrigerator 100. Simultaneously, the combined design of the inner airbag 331 and the outer airbag 332 forms a double-sealing structure. The inner airbag 331 prevents cold air from escaping from the air duct, while the outer airbag 332 prevents air from flowing in from outside the air duct, significantly improving the sealing performance of the sealing ring 32, enhancing the refrigerator 100's insulation performance, and reducing energy loss. The outer ring airbag 332 has the following effects: a double sealing structure, which forms a double sealing structure with the inner ring airbag 331. The inner ring airbag can prevent cold air in the air duct from leaking outward, and the outer ring airbag can prevent ambient air outside the air duct from intruding inward. The combination of the two greatly improves the sealing performance; heat insulation and improved energy efficiency: the still air layer in the inner ring airbag 331 and the outer ring airbag 332 forms an effective heat insulation layer, which significantly reduces the cold loss and heat exchange at the air duct interface, thereby improving the cooling efficiency and reducing energy consumption; structural stability: the outward flange abuts against the air duct plate, providing additional support and positioning for the entire sealing device, making it less prone to displacement or deformation when subjected to external forces.

[0055] In some embodiments of this application, the sealing ring 32 further includes a sealing edge 324. The sealing edge 324 is connected to the side of the outward flange 323 away from the mating portion 321, and the sealing edge 324 abuts against the side of the air duct plate 101 opposite to the fixing ring 31. An outer ring airbag 332 is formed between the sealing edge 324, the outward flange 323, the mating portion 321, the fixing portion 311, and the air duct plate 101. Thus, the addition of the sealing edge 324 provides an additional sealing interface for the outward flange 323, and the combination of the outward flange 323 and the air duct plate 101 further improves the sealing performance of the sealing ring 32, ensuring more effective prevention of air and moisture leakage. The abutment between the sealing edge 324 and the air duct plate 101 provides additional support and stability to the sealing ring 32, ensuring that the sealing ring 32 maintains a good position and shape during use. The design of the sealing edge 324 enables the outer ring airbag 332 to better disperse and absorb external pressure and impact, enhancing the pressure resistance and impact resistance of the sealing device 30.

[0056] In some embodiments of this application, the sealing edge 324 extends radially toward the mating part 321 along the openings of the housing air duct 12 and the door air duct 21, thereby reducing the gap between the outer ring airbag 332 and the air duct plate 101 and improving the sealing effect. In some embodiments of this application, the fixing part 311 is provided with a first buckle 314 and a second buckle 315. The mating part 321 is provided with a first snap 325 and a second snap 326. Along the radial direction of the openings of the housing air duct 12 and the door air duct 21, the first buckle 314 and the second buckle 315 are arranged opposite to each other, the first buckle 314 is snapped to the first snap 325, and the second buckle 315 is snapped to the second snap 326. In this way, by using the combination of two buckles and two snaps, the connection is more stable, ensuring that the sealing ring will not easily loosen or fall off during use, and maintaining the stable performance of the sealing device. The design of double buckles and snaps provides a more uniform pressure distribution, which helps to improve the sealing effect of the sealing ring and reduce the leakage of air and moisture. The double-buckle design also helps to make alignment and fixation easier during installation, simplifying the installation steps and reducing the possibility of errors. In some embodiments of this application, the first buckle 325 and the second buckle 326 are generally V-shaped buckles; the first inverted buckle 314 and the second inverted buckle 315 are locking steps formed on one side of the mating groove 3111, so that when the first buckle 325 and the second buckle 326 can be elastically deformed to engage with the fixing part 311, that is, when the first buckle 325 and the second buckle 326 are inserted into the mating groove 3111, they are held by the first inverted buckle 314 and the second inverted buckle 315.

[0057] In some embodiments of this application, multiple first buckles 314 and second buckles 315 are provided. The multiple first buckles 314 and multiple second buckles 315 are sequentially arranged around the circumference of the openings of the housing air duct 12 and the door air duct 21. In some embodiments, the first buckles 314 and second buckles 315 are spaced apart around the circumference of the openings of the housing air duct 12 and the door air duct 21, thereby improving the stability of the snap-fit ​​connection between the fixing part 311 and the mating part 321. In some embodiments, the first buckles 314 and second buckles 315 are evenly arranged around the circumference of the openings of the housing air duct 12 and the door air duct 21. In some embodiments of this application, the first buckles 325 and second buckles 326 are oppositely disposed on the mating part 321, and the first buckles 325 and second buckles 326 are respectively annular around the circumference of the openings of the housing air duct 12 and the door air duct 21. The annular first clip 325 and second clip 326 reduce the difficulty of connecting the first inverted clip 314 to the first clip 325, and the second inverted clip 315 to the second clip 326, making it easier for users to install and fix. The annular first clip 325 and second clip 326 also improve the stability of the connection between the first inverted clip 314 and the first clip 325, and the second inverted clip 315 to the second clip 326, thereby fixing the sealing device 30 to the air duct opening 12 of the housing and the air duct opening 21 of the door.

[0058] The refrigerator 100 provided in some embodiments of this application includes a cabinet 10, a door 20, an ice maker, and a sealing device 30. A storage compartment 11 is formed inside the cabinet 10, and an air duct 12 is provided on the inner wall of the storage compartment 11. The door 20 is rotatably mounted on the cabinet 10 and is used to close the opening of the storage compartment 11. An air duct 21 is provided on the door 20 opposite to the air duct 12. The ice maker is disposed on the door 20 and communicates with the air duct 21. In some embodiments of this application, the sealing device 30 is integrally mounted on the door 20 and arranged around the air duct 21. Therefore, the sealing device 30, as part of the door, moves together with the rotation of the door 20. The sealing device 30 includes a retaining ring 31 and a sealing ring 32. In some embodiments, the fixing ring 31 is stably fixed to the door duct opening 21, while the sealing ring 32, which plays a major sealing role, is connected to the fixing ring 31 and faces the housing 10. One or more airbags 33 can be formed between the sealing ring 32 and the fixing ring 31, surrounding the airflow channel of the duct opening. Thus, when the door 20 is closed by the user, as the door duct opening 21 on it gradually approaches and finally aligns with the housing duct opening 12 on the housing 10, the entire sealing device 30 pre-installed on the door 20 will be tightly pressed against and squeezed against the wall surface around the duct opening 12 on the housing 10. At this time, the elastic sealing structure composed of the sealing ring 32 and the airbag 33 can effectively fill and seal the gap between them, thereby ensuring the airtightness of the ice-making circulation duct and preventing cold air leakage and humid and hot air intrusion. In some embodiments, the sealing device 30 can also be fixed as a whole to the housing duct opening 12, and squeezed by the corresponding structure on the door when the door is closed, with a sealing principle similar to some of the embodiments described above.

[0059] Thus, a sealing device 30 is installed between the air duct opening 12 of the cabinet and the air duct opening 21 of the door. The sealing device 30 includes a sealing ring 32 and a fixing ring 31. Through the connection of the sealing ring 32 and the fixing ring 31, the sealing device 30 is fixed to the air duct opening 12 of the cabinet and the air duct opening 21 of the door. Multiple airbags 33 are formed between the sealing ring 32 and the fixing ring 31. The multiple airbags 33 surround the openings of the air duct opening 12 of the cabinet and the air duct opening 21 of the door, which can effectively isolate the airflow between the air duct and the outside air, thereby improving the sealing performance and reducing cold air leakage. This helps to improve the temperature stability of the door 20, ensuring that the ice maker can obtain a stable cold airflow, thereby improving the ice making efficiency and speed. Furthermore, the airbags 33 are arranged around the openings of the air ducts. The airbags 33 contain gas. Since the heat conduction efficiency of gas is low, the heat exchange between the door 20 and the cabinet 10 is further reduced, resulting in high heat preservation effect and improved cooling effect on the door 20, thereby improving the efficiency of the ice maker on the door.

[0060] After improving the sealing device through several embodiments, effectively solving the sealing and insulation problems of the air duct opening from the perspectives of energy efficiency and cold transfer, and ensuring that the door-mounted ice-making system can obtain a stable and efficient cold source, the inventors of this application further discovered that in order to improve the performance of the door-mounted ice-making system, in addition to improving its operating efficiency, the rationality of its mechanical structure and the convenience of user interaction are equally important. Specifically, the inventors noted that there is room for improvement in the installation and fixing method of the ice storage box in related technologies. The ice storage box in related technologies usually requires an independent bracket system to fix it to the door frame. This bracket design not only increases the cost of components and the complexity of supply chain management, but also makes the installation process more cumbersome. It is also prone to inaccurate positioning or difficulty in disassembly and assembly due to tolerances accumulated during manufacturing and assembly, affecting the overall user experience. To this end, some embodiments of this application also provide an improved installation structure for the ice storage box. By setting positioning and fixing features on the door body that directly cooperate with the ice storage box, the overall structure is simplified, production costs are reduced, and users can install and disassemble the ice storage box more conveniently and accurately.

[0061] Refrigerators in related technologies typically have ice-making units with ice storage trays that need to be easily removed for cleaning. They also need to be easily and quickly placed when installed on the door. In related technologies, refrigerators install ice storage tray brackets on the door, and then fix the ice storage trays to the brackets for securing and removing them. However, the ice storage tray bracket itself needs to be fixed to the door liner, which not only increases production costs but also causes inconvenience during installation due to increased misalignment between the ice storage tray and the bracket. After repeated consideration and verification, the inventors discovered that if an independent space is designed on the door, allowing the ice storage tray to be placed removably within this space, and by setting mutually cooperating fixing components on the walls of this space and on the ice storage tray, and using the walls of the space to position the ice storage tray, the ice storage tray can be directly installed on the door, eliminating the traditional ice storage tray bracket and simplifying the internal structure of the refrigerator.

Figure 12 is a partially exploded structural schematic diagram of the refrigerator door shown in Figure 11. Figure 13 is a structural schematic diagram of a refrigerator door provided in some embodiments of this application. Figure 14 is a partially exploded structural schematic diagram of the refrigerator door shown in Figure 13.

[0063] As shown in Figures 11 and 13, the refrigerator 100 provided in some embodiments of this application includes a cabinet and a door 20. The cabinet has a storage compartment. The door 20 is rotatably mounted on the cabinet and can close the storage compartment. The refrigerator 100 provided in some embodiments of this application also includes an ice-making device 1001. A door liner 21 is provided in the door 20. The door liner 21 forms an accommodating space 22. The ice-making device 1001 is disposed in the accommodating space 22. The ice-making device 1001 is used to make ice cubes. Referring to Figures 12 and 14, the accommodating space 22 includes a positioning cavity 23 located at the bottom. The ice-making device 1001 includes an ice storage box 1111. The ice storage box 1111 is disposed in the positioning cavity 23. The ice storage box 1111 has an ice-containing cavity 101, which is used to store and process ice cubes.

[0064] The ice-making apparatus 1001 provided in some embodiments of this application also includes an ice maker. The ice maker is disposed in the accommodating space 22 and located above the ice storage box 1111. Referring to FIG19, along the height direction of the door 20, the bottom of the positioning cavity 23 is provided with a first holding part 24, and the bottom of the ice storage box 1111 is provided with a second holding part 111. The first holding part 24 and the second holding part 111 are disposed opposite to each other, and the first holding part 24 and the second holding part 111 are engaged with each other, thereby fixing the ice storage box 1111 in the positioning cavity 23 along the opening direction of the accommodating space 22. Along the width direction of the door 20, the positioning cavity 23 has a first side wall 231 and a second side wall 232 disposed opposite to each other. Along the width direction of the door 20, the ice storage box 1111 has a first box wall 102 and a second box wall 103 disposed opposite to each other. The first sidewall 231 abuts against the first box wall 102, and the second sidewall 232 abuts against the second box wall 103, thereby restricting the movement of the ice storage box 1111 in the width direction of the door and thus positioning the ice storage box 1111. A first retaining part 24 is provided at the bottom of the positioning cavity 23, and a second retaining part 111 is provided at the bottom of the ice storage box 1111. The first retaining part 24 and the second retaining part 111 engage with each other, thus fixing the ice storage box 1111 in the positioning cavity 23. Simultaneously, relying on the relatively arranged first sidewall 231 and second sidewall 232 of the positioning cavity 23, with the first sidewall 231 abutting against the first box wall 102 and the second sidewall 232 abutting against the second box wall 103, the ice storage box 1111 is further positioned, ultimately achieving stable fixation of the ice storage box 1111 on the door 20. By directly mounting the ice storage box 1111 onto the door 20, the ice storage box bracket of related technologies can be omitted, simplifying the internal structure of the refrigerator 100. Since the ice storage box 1111 directly engages with the locking components of the door 20, the complexity of the installation process is reduced, and deviations during installation can be effectively controlled. Reducing the number of brackets also lowers the risk of errors during production and assembly. Simultaneously, the simplified structural design makes the installation and removal of the ice storage box 1111 more intuitive and convenient, allowing users to operate and maintain it more easily in daily use. Furthermore, reducing additional components such as brackets may also reduce the overall weight and cost of the refrigerator 100.

[0065] In some embodiments of this application, one of the first latching part 24 and the second latching part 111 is a latch, and the other is a latch. This combination of latch and latch makes the connection between the ice storage box 1111 and the positioning cavity 23 more secure. The latching design effectively prevents the ice storage box 1111 from shaking or shifting when the door 20 is opened and closed, ensuring the stability of the ice storage box 1111 during use. Furthermore, the combination of latch and latch makes the installation and removal of the ice storage box 1111 simpler and faster. Users only need to align the latch and latch to easily latch or separate them, without the need for tools, improving user convenience. Since the latch and latch require specific alignment and force, it can also prevent misinstallation or loosening of the ice storage box 1111 to a certain extent, reducing the probability of errors during installation.

[0066] In some embodiments of this application, the first holding part 24 is a buckle, and the second holding part 111 is a latch. The buckle 24 has a holding surface 241 on the side facing away from the opening of the accommodating space 22, and the holding surface 241 engages with the latch 111. This arrangement, with the holding surface 241 on the side facing away from the opening of the accommodating space 22 and engaging with the latch, increases the contact area between the buckle and the latch, strengthening the fixing effect of the buckle and latch. This ensures the ice storage box 1111 is more secure after installation, reducing the possibility of shaking and displacement, and effectively preventing the ice storage box 1111 from accidentally falling off due to external force or vibration during use. Simultaneously, the presence of the holding surface 241 requires specific operation to remove the ice storage box 1111 from the latch, increasing safety.

[0067] In some embodiments of this application, a guide surface 242 is provided on the side of the latch facing the opening of the receiving space 22. Along the opening direction of the receiving space 22, the guide surface 242 is inclined downwards near the opening. This inclined design of the guide surface 242 on the side of the latch facing the opening of the receiving space 22 provides natural guidance for the installation of the ice storage box 1111, making it easier for the user to align the latch and the locking mechanism when pushing the ice storage box 1111 into the receiving space 22, reducing the difficulty of alignment during installation and improving the convenience of user operation. The inclined guide surface 242 also helps the user automatically correct the position of the ice storage box 1111 during installation, reducing the risk of installation errors due to misalignment and ensuring that the ice storage box 1111 is installed correctly every time. The guide surface 242 provides a smooth transition area, making the ice storage box 1111 easier to install and remove, reducing jamming and improving the user's operating experience. The guide surface 242 can also reduce wear and impact on the clips and latches during installation, thereby extending their service life.

[0068] In some embodiments of this application, two first retaining portions 24 are provided along the width direction of the door body 20. Two second retaining portions 111 are provided opposite each other at the bottom of the ice storage box 1111. The cooperation between the two first retaining portions 24 and the second retaining portions 111 improves the stability of the ice storage box 1111 in the positioning cavity 23. In some embodiments of this application, a limiting portion 233 is provided on the bottom wall of the positioning cavity 23 along the thickness direction of the door body 20, and a mating portion 112 is provided on the side of the ice storage box 1111 facing the accommodating space 22. The mating portion 112 and the limiting portion 233 are arranged opposite each other to restrict the movement of the ice storage box 1111. In this way, the relative arrangement of the limiting portion 233 and the mating portion 112 provides additional fixing support, restricts the movement of the ice storage box 1111 in the accommodating space 22, and ensures that the ice storage box 1111 remains stable when the door body 20 of the refrigerator 100 is opened and closed, and will not slide or tilt due to inertia, thereby improving safety. The cooperation between the limiting part 233 and the mating part 112 ensures the precise positioning of the ice storage box 1111 within the positioning cavity 23, preventing misalignment of the ice storage box 1111. In some embodiments of this application, the limiting part 233 is disposed near the first side wall 231 and the second side wall 232. The mating part 112 is disposed on both sides of the ice storage box 1111, thereby directly positioning the ice storage box 1111 in the positioning cavity 23 from both sides.

Figure 17 is a structural schematic diagram of the ice storage box shown in Figure 12. Figure 18 is an exploded structural schematic diagram of the ice storage box shown in Figure 17. Figure 19 is a structural schematic diagram of the ice storage box shown in Figure 12 from another perspective. Figure 20 is an exploded structural schematic diagram of the ice storage box shown in Figure 19.

[0070] Please refer to Figures 15 and 17 simultaneously. In some embodiments of this application, the ice storage container 1111 is provided with a handle 113. The handle 113 is located on the side of the ice storage container 1111 opposite to the receiving space 22. This design of the handle 113 allows users to more easily grasp and operate the ice storage container 1111. Whether installing, removing, or taking ice cubes, the handle 113 provides a convenient gripping point, improving the user's operating experience. Positioning the handle 113 on the side of the ice storage container 1111 opposite to the receiving space 22 not only facilitates user operation but also provides an intuitive visual and tactile cue, enabling users to quickly identify the correct operating method of the ice storage container 1111 and reducing the possibility of misoperation. In some embodiments of this application, the handle 113 is a groove located at the bottom of the ice storage container 1111. In this way, the user can grab the ice storage box 1111 from the bottom, which is convenient to operate. It is also adjacent to the second holding part 111, which makes it easy to fine-tune the position of the bottom of the ice storage box 1111, so that the ice storage box 1111 can be quickly placed in place.

[0071] Please refer to Figures 16, 18, and 20 simultaneously. In some embodiments of this application, the ice storage box 1111 includes a support base 12, a mounting base 13, and a receiving base 14. The mounting base 13 and the receiving base 14 are respectively disposed on the support base 12. In this way, the support base provides a solid foundation to ensure the overall structural stability of the ice storage box. An ice-containing cavity 101 is formed between the mounting base 13 and the receiving base 14. An ice crusher 16 is disposed on the mounting base 13 and is located in the ice-containing cavity 101. The ice-containing cavity 101 formed between the mounting base 13 and the receiving base 14 provides a dedicated space for storing and processing ice. Furthermore, the ice crusher 16 disposed on the mounting base 13 and located in the ice-containing cavity 101 can quickly process the stored ice, thereby realizing the integration of ice making and ice crushing, improving the efficiency of ice making and ice crushing, and meeting the diverse needs of users. In some embodiments of this application, the second holding part 111 and the handle part 113 are disposed on the support base 12. A mating part 112 is formed between the support base 12 and the mounting base 13. In some embodiments of this application, the support base 12 includes a third side wall 121 and a fourth side wall 122 disposed opposite to each other. Positioning grooves 123 are respectively provided on the opposite sides of the third side wall 121 and the fourth side wall 122. A positioning element 131 is provided on the mounting base 13 opposite to the positioning groove 123. The positioning element 131 cooperates with the positioning groove 123 to position the mounting base 13 on the support base 12. Thus, the cooperation between the positioning groove 123 and the positioning element 131 ensures the precise positioning of the mounting base 13 on the support base 12, reduces installation errors, and ensures that each component maintains the correct position and alignment during use. The positioning groove 123 and the positioning element 131 also provide clear installation guidance, making it more intuitive and simple for users to assemble the ice storage box 1111. Installation can be completed simply by aligning the positioning element 131 with the positioning groove 123, reducing installation difficulty and time. The combination of positioning groove 123 and positioning element 131 can also provide a stable fixation for mounting base 13, reducing the shaking and displacement of mounting base 13 during operation and improving the overall stability of the device.

[0072] In some embodiments of this application, both the positioning groove 123 and the positioning element 131 are elongated, thereby improving the stability of the positioning connection between the mounting base 13 and the support base 12. In some embodiments of this application, a slot 124 is provided on the support base 12 along the height direction of the door body 20. A locking block 141 is provided on the receiving base 14 opposite to the slot 124. The locking block 141 is disposed in the slot 124 to position the receiving base 14 on the support base 12. In this way, the positioning cooperation between the slot 124 and the locking block 141 ensures the precise positioning and stable fixation of the receiving base 14 on the support base 12, reduces installation errors, and ensures that each component maintains the correct position and alignment during use. The slot 124 and the locking block 141 also provide clear installation guidance, making it more intuitive and simple for users to assemble the ice storage box 1111. They only need to align the locking block 141 with the slot 124 and insert it to complete the installation, reducing the installation difficulty and time. The combination of the slot 124 and the block 141 can reduce the shaking and displacement of the receiving seat 14 during operation, thereby improving the overall stability of the device.

[0073] In some embodiments of this application, the opening of the slot 124 faces upward. The receiving seat 14 is inserted into the support seat 12 from above. In some embodiments of this application, there are multiple slots 124, each disposed on the support seat 12. These slots can be located at the top of the third side wall 121 and the fourth side wall 122, on the inner side of the wall connecting the third side wall 121 and the fourth side wall 122, or at the bottom of the support seat 12 where the second holding part 111 is provided. In some embodiments of this application, the third side wall 121 and the fourth side wall 122 are respectively provided with first fixing holes 125. The mounting seat 13 is provided with a first fixing groove 132 opposite to the first fixing hole 125. A fastener passes through the first fixing hole 125 and the first fixing groove 132 to fix the mounting seat 13 to the support seat 12. Thus, by using a fastener passing through the first fixing hole 125 and the first fixing groove 132, the connection between the mounting seat 13 and the support seat 12 is more secure. The design of the first fixing hole 125 and the first fixing groove 132 makes the installation and disassembly process more intuitive and simple. Users only need to insert the fastener into the corresponding hole or groove to complete the installation or disassembly, reducing the complexity of the operation.

[0074] In some embodiments of this application, the first fixing hole 125 is located on the extension line of the positioning groove 123, and the first fixing groove 132 is located on the extension line of the positioning member 131, thereby improving the stability of positioning and preventing the mounting base 13 from shaking during use after positioning. In some embodiments of this application, a second fixing groove 126 is provided on the support base 12 along the thickness direction of the door body 20. The mounting base 13 and the receiving base 14 are provided with a second fixing hole 15 opposite to the second fixing groove 126. The fixing member passes through the second fixing hole 15 and the second fixing groove 126 to fix the mounting base 13 and the receiving base 14 to the support base 12. In this way, by using the fixing member passing through the second fixing hole 15 and the second fixing groove 126, the connection between the mounting base 13 and the receiving base 14 and the support base 12 is more secure. The design of the second fixing hole 15 and the second fixing groove 126 makes the installation and disassembly process more intuitive and simple. Users only need to insert the fixing member into the corresponding hole or groove to complete the installation or disassembly, reducing the complexity of operation. Meanwhile, by fixing the mounting base 13 and the receiving base 14 to the support base 12 through the second fixing hole 15 and the second fixing groove 126, the three are directly connected to each other, avoiding excessive deviation after installation, which would prevent the ice storage box 1111 from being installed into the positioning cavity 23. The user lifts the ice storage box 1111 by grasping the handle 113, initially placing it in the receiving space 22 of the door body 20. The user aligns the second holding part 111 at the bottom of the ice storage box 1111 with the first holding part 24, and the ice storage box 1111 falls under its own weight and is installed in the position of the first holding part 24 of the door body 20, thereby fixing the ice storage box 1111 in the front-back direction. The first side wall 231 and the second side wall 232 on the left and right sides of the positioning cavity 23 further fix the ice storage box 1111, finally achieving stable fixation of the ice storage box 1111.

[0075] The refrigerator 100 provided in some embodiments of this application includes a cabinet, a door 20, and an ice storage box 1111. The door 20 is rotatably mounted on the cabinet, and a door liner 21 is provided in the door 20, forming an accommodating space 22. The ice storage box 1111 is disposed in the accommodating space 22. Along the width direction of the door 20, the ice storage box 1111 has a first box wall 102 and a second box wall 103 disposed opposite to each other. Along the height direction of the door 20, a first retaining part 24 is provided at the bottom of the accommodating space 22, and a second retaining part 111 is provided at the bottom of the ice storage box 1111. The first retaining part 24 and the second retaining part 111 are engaged with each other. Along the width direction of the door 20, the accommodating space 22 has a first side wall 231 and a second side wall 232 disposed opposite to each other. The first side wall 231 abuts against the first box wall 102, and the second side wall 232 abuts against the second box wall 103 to position the ice storage box 1111. Thus, a first retaining part 24 is provided at the bottom of the accommodating space 22, and a second retaining part 111 is provided at the bottom of the ice storage box 1111. The first retaining part 24 and the second retaining part 111 are interlocked to fix the ice storage box 1111 in the accommodating space 22. At the same time, relying on the oppositely arranged first side wall 231 and second side wall 232 of the accommodating space 22, the ice storage box 1111 is further positioned by the first side wall 231 abutting against the first box wall 102 and the second side wall 232 abutting against the second box wall 103, ultimately achieving stable fixation of the ice storage box 1111 on the door 20. By directly installing the ice storage box 1111 on the door 20, the traditional ice storage box bracket can be omitted, simplifying the internal structure of the refrigerator 100. Since the ice storage box 1111 is directly interlocked with the retaining parts of the door 20, the complexity of the installation process is reduced, and deviations during the installation process can be effectively controlled. By reducing the bracket, the error risk in the production and assembly process can also be reduced.
