Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of household appliances, in particular to a refrigerator. BACKGROUND

[0002] The refrigerator is a refrigeration equipment keeping constant low temperature, and is also a civil product keeping constant low temperature of food or other objects. In the prior art, an ice making device is installed on the door of the refrigerator to make ice and meet the demand of the user for ice.

[0003] The ice making system on the door needs to design a door body air duct on the door. When the door is closed, the door body air duct is connected with the cabinet air duct to send the cold air in the cabinet to the ice making system to provide a cold source for the ice making system. A sealing element needs to be designed at the air supply connection position between the door and the cabinet to seal the interface corresponding to the cabinet air duct and the door body air duct when the door is closed.

[0004] However, in the prior art, the sealing effect of the sealing element at the air duct connection position is not good, and there is a gap, which affects the cold air transmission of the ice making system on the door and reduces the efficiency of the ice making system on the door. SUMMARY

[0005] The embodiment of the present application provides a refrigerator, which has good sealing performance at the connection position of the door body air duct and the cabinet air duct, so that the efficiency of the ice making system on the door is improved, and the user experience is improved.

[0006] In a first aspect, the embodiment of the present application provides a refrigerator, comprising:

[0007] A cabinet, the inside of the cabinet is formed with a storage room, and the inner wall surface of the storage room is provided with a cabinet air duct opening;

[0008] A door body, the door body is rotatably arranged on the cabinet, and the door body is used to close the opening of the storage room. The position of the door body relative to the cabinet air duct opening is provided with a door body air duct opening;

[0009] An ice making device, the ice making device is arranged on the door body and communicates with the door body air duct opening;

[0010] When the door body closes the opening of the storage room, the cabinet air duct opening is connected with the door body air duct opening;

[0011] A sealing device, the sealing device is arranged at the cabinet air duct opening and / or the door body air duct opening to seal the connection position of the cabinet air duct opening and the door body air duct opening when the cabinet air duct opening is connected with the door body air duct opening;

[0012] The sealing device comprises:

[0013] A fixing ring, the fixing ring is arranged on the side of the cabinet air duct opening and / or the door body air duct opening away from the other;

[0014] The sealing ring is arranged on one side of the cabinet air duct opening and / or the door air duct opening facing the other, and is connected with the fixing ring.

[0015] A plurality of air bags are formed between the fixing ring and the sealing ring, and are arranged around the opening of the cabinet air duct or the door air duct.

[0016] In this way, the sealing device is arranged between the cabinet air duct opening and the door air duct opening, and includes a sealing ring and a fixing ring. The sealing device is fixed on the cabinet air duct opening and the door air duct opening through the connection of the sealing ring and the fixing ring. A plurality of air bag structures are formed between the sealing ring and the fixing ring, and a plurality of air bags are arranged around the opening of the cabinet air duct and the door air duct. The air bags can effectively cut off the circulation of air between the air duct and the outside air, thereby improving the sealing performance and reducing the leakage of cold air. This helps to improve the stability of the temperature on the door body and ensures that the ice making device can obtain stable cold air flow, thereby improving the ice making efficiency and speed. Moreover, the air bags are arranged around the opening of the air duct, and there is gas in the air bags. Since the heat conduction efficiency of the gas is low, the heat exchange between the door body and the cabinet is further reduced, the heat preservation effect is high, the refrigeration effect on the door body is improved, and thus the efficiency of the ice making device on the door is improved.

[0017] In some embodiments of the present application, the side of the fixing ring facing the sealing ring is provided with a fixing part, and the side of the sealing ring facing the fixing ring is provided with a matching part. The fixing part and the matching part are mutually buckled.

[0018] In this way, the fixing part and the matching part are mutually buckled to provide a more secure connection, ensuring that the sealing ring will not easily fall off or shift during use, thereby maintaining long-term stable sealing effect. The buckling structure makes the installation and disassembly of the sealing ring more convenient, without the need for complex tools or processes, facilitating users or maintenance personnel to replace and maintain. At the same time, the buckling design can compensate for errors in the manufacturing and installation process to some extent, ensuring good cooperation between the sealing ring and the fixing ring, further improving the sealing performance, and ensuring the stability of the temperature inside the refrigerator and the improvement of energy efficiency.

[0019] In some embodiments of the present application, one of the fixing part and the matching part is a buckle, and the other is a reverse buckle.

[0020] In this way, the cooperation of the buckle and the reverse buckle makes the connection between the sealing ring and the fixing ring more stable, reducing the risk of loosening or falling off. The cooperation of the buckle and the reverse buckle makes the installation process more intuitive and simple, usually only needs to be pressed lightly to achieve buckling, without the need for tools to complete the operation, reducing the installation time and complexity, and improving the convenience of users. At the same time, the close combination of the buckle and the reverse buckle can effectively resist the vibration caused by the opening of the refrigerator door or other external factors, maintaining the stability of the sealing device. Because the cooperation of the buckle and the reverse buckle requires specific alignment and force, it can also prevent the sealing ring and the fixing ring from being misassembled or loosened to some extent, reducing the error probability of users during installation.

[0021] In some embodiments of the present application, the fixing part is a reverse buckle, the cooperation part is a buckle, and the opening of the cabinet air duct and the door air duct is provided with an air duct plate, and the reverse buckle penetrates the air duct plate.

[0022] In this way, the reverse buckle penetrates the air duct plate, providing additional support and fixation, making the sealing device more stable during use, and reducing displacement or loosening caused by external forces. With the support of the air duct plate, the combination of the reverse buckle and the buckle is more closely, further improving the sealing performance, reducing cold air leakage, and improving the energy efficiency of the refrigerator. At the same time, the reverse buckle penetrates the air duct plate, which can help users to align the buckle position more easily during installation, simplify the installation steps, and reduce installation errors.

[0023] In some embodiments of the present application, the fixing ring further comprises an abutting part, the abutting part is connected with the fixing part, and the abutting part abuts with the side of the air duct plate away from the sealing ring.

[0024] In this way, the abutting part provides additional support, making the fixing ring more stable when subjected to external forces, preventing the fixing ring and the sealing ring from being displaced during use, ensuring the continuous effectiveness of the sealing device, and enhancing the strength and durability of the overall structure. The contact of the abutting part with the air duct plate provides a stable support surface, ensuring that the sealing ring maintains a good position and shape during use, thereby improving the sealing reliability. At the same time, the design of the abutting part helps to absorb and disperse the vibration caused by the operation of the refrigerator or the opening and closing of the door, reducing the impact on the sealing device and maintaining its performance stability.

[0025] In some embodiments of the present application, the air bag comprises an inner ring air bag, the sealing ring further comprises an inner flange, the inner flange is connected with the cooperation part, and the inner flange is folded inward and abuts against the fixing part along the radial direction of the opening of the cabinet air duct and the door air duct, and the inner flange, the cooperation part and the fixing part form the inner ring air bag.

[0026] Thus, the design of the inner turning edge makes the connection between the sealing ring and the fixed part more stable, reduces displacement or deformation of the sealing ring during use. The inner ring air bag can provide flexible cushioning when the refrigerator door is closed, reducing direct impact on the sealing ring and prolonging the service life of the sealing ring. The flexibility of the inner ring air bag can also reduce the noise generated when the refrigerator door is closed, providing a quieter use environment. The design of the inner ring air bag provides an additional sealing layer, which can more effectively prevent air and moisture leakage, improving the sealing performance and energy efficiency of the refrigerator.

[0027] In some embodiments of the present application, the fixed ring further comprises a sealing part, the sealing part is connected to the side of the fixed part away from the abutting part, and the inner turning edge abuts the sealing part. The sealing part, the inner turning edge, the matching part and the fixed part form an inner ring air bag.

[0028] Thus, the sealing part provides an additional sealing interface for the inner turning edge, further improving the sealing performance of the sealing ring and ensuring more effective prevention of air and moisture leakage. The presence of the sealing part also improves the pressure resistance of the inner ring air bag, making the structure of the inner ring air bag more stable and reducing deformation of the inner ring air bag under pressure changes, thereby maintaining consistent sealing effect.

[0029] In some embodiments of the present application, the air bag comprises an outer ring air bag, and the sealing ring further comprises an outer turning edge, the outer turning edge is connected to the matching part, and the outer turning edge is folded outward along the radial direction of the opening of the box air duct and the door air duct, and abuts the air duct plate. The outer turning edge, the matching part, the fixed part and the air duct plate form an outer ring air bag.

[0030] Thus, the design of the outer turning edge makes the connection between the sealing ring and the air duct plate more stable, reducing displacement or deformation of the sealing ring during use. When subjected to external force, the outer turning edge can better disperse and absorb the impact, reducing wear and tear and improving the durability of the sealing device. The outer ring air bag can better adapt to the pressure changes inside and outside the refrigerator, providing flexible cushioning when the refrigerator door is closed, reducing direct impact on the sealing ring and prolonging the service life of the sealing ring. The flexibility of the outer ring air bag can also reduce the noise generated when the refrigerator door is closed, providing a quieter use environment. The design of the outer ring air bag provides an additional sealing layer, which can more effectively prevent air and moisture leakage, improving the sealing performance and energy efficiency of the refrigerator.

[0031] In combination with the design of the inner ring air bag and the outer ring air bag, a double sealing structure is formed, significantly improving the heat preservation performance of the refrigerator and reducing energy loss.

[0032] In some embodiments of the present application, the sealing ring further comprises a sealing edge, the sealing edge is connected to the side of the outer turning edge away from the matching part, and the sealing edge abuts the side of the air duct plate away from the fixed ring. The sealing edge, the outer turning edge, the matching part, the fixed part and the air duct plate form an outer ring air bag.

[0033] In this way, the addition of the sealing edge provides an additional sealing interface for the outer flange, which, in combination with the outer flange and the air duct plate, further improves the sealing performance of the sealing ring, ensuring more effective prevention of air and moisture leakage. The abutment of the sealing edge with the air duct plate provides additional support and stability, ensuring that the sealing ring maintains good position and shape during use. The design of the sealing edge allows the outer ring air bag to better disperse and absorb external pressure and impact force, enhancing the pressure resistance and impact resistance of the sealing device.

[0034] In some embodiments of the present application, the fixing part is provided with a first undercut and a second undercut, and the cooperating part is provided with a first buckle and a second buckle. Along the radial direction of the opening of the box air duct and the door air duct, the first undercut and the second undercut are oppositely arranged, the first undercut is buckled connected with the first buckle, and the second undercut is buckled connected with the second buckle.

[0035] In this way, by using the combination of two undercuts and two buckles, the connection is more stable, ensuring that the sealing ring will not easily loosen or fall off during use, maintaining the performance stability of the sealing device. The design of the double undercuts and buckles provides more uniform pressure distribution, which helps to improve the sealing effect of the sealing ring and reduce air and moisture leakage. The design of the double buckles also helps to align and fix more easily during installation, simplifying the installation steps and reducing the possibility of errors. BRIEF DESCRIPTION OF DRAWINGS

[0055] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0056] The refrigerator is a refrigeration device that keeps a constant low temperature, and is also a civil product that keeps food or other objects in a constant low temperature state. In the prior art, an ice making device is installed on the door of the refrigerator to make ice to meet the user's demand for ice cubes.

[0057] The ice making system on the door needs to design a door body air duct on the door. When the door is closed, the door body air duct is connected with the cabinet air duct to send cold air in the cabinet to the ice making system to provide a cold source for the ice making system. Sealing elements are needed to be designed at the air supply connection between the door and the cabinet to seal the interface corresponding to the cabinet air duct and the door body air duct when the door is closed.

[0058] However, in the prior art, the sealing effect of the sealing element at the air duct connection position is not good, there is a gap, which affects the cold air transmission of the ice making system on the door, and reduces the efficiency of the ice making system on the door.

[0059] After repeated thinking and verification, the inventors found that if the sealing element between the door and the cabinet is provided as two structural elements, the two structural elements are fixed from both sides of the air duct opening, and a plurality of air bags are formed around the opening of the air duct opening. The plurality of air bags arranged around the air duct opening can effectively block the circulation of air between the air duct and the outside air, thereby improving the sealing performance and reducing the leakage of cold air, so as to ensure that the ice making device can obtain stable cold air flow and improve the ice making efficiency and speed.

[0060] Figure 1 The structure of the refrigerator provided in the embodiments of the present application is shown in the schematic diagram. Figure 2 For Figure 1 The structure of the refrigerator provided in the embodiments of the present application is shown in the schematic diagram.

[0061] As Figure 1 and Figure 2 The refrigerator 100 provided in the embodiments of the present application includes a cabinet 10 and a door body 20. The cabinet 10 has a storage compartment 11. The storage compartment 11 is used for users to place food that needs to be refrigerated. The door body 20 is rotatably arranged on the cabinet 10, and the door body 20 is used to close the opening of the storage compartment 11.

[0062] In some embodiments of the present application, the cabinet 10 has an inner container, and the inner container forms the storage compartment 11 inside.

[0063] The cabinet 10 is provided with a cold air passage. The cold air passage is used to provide cold energy for the refrigerator 100.

[0064] The refrigerator 100 provided in the embodiments of the present application further includes an ice making device. The ice making device is arranged on the door body 20. An inner wall surface of the storage compartment 11 is provided with a cabinet air duct opening 12. The cabinet air duct opening 12 is in communication with the cold air passage. The door body 20 is provided with a door body air duct opening 21 at a position opposite to the cabinet air duct opening 12. The ice making device is in communication with the door body air duct opening 21.

[0065] When the door body 20 closes the opening of the storage chamber 11, the cabinet air duct opening 12 and the door body air duct opening 21 are connected, so that the cold air in the cold air passage in the cabinet 10 enters the door body 20 through the cabinet air duct opening 12 and the door body air duct opening 21, providing cold energy for the ice making device, so as to facilitate ice making of the ice making device.

[0066] In some embodiments of the present application, the door body 20 is provided with a door tank, and a space for accommodating the ice making device is formed in the door tank. The door body air duct opening 21 is arranged on the door tank.

[0067] In some embodiments of the present application, the cabinet air duct opening 12 includes a cabinet air inlet 121 and a cabinet air return 122. The door body air duct opening 21 includes a door body air inlet 211 and a door body air return 212. The cabinet air inlet 121 is opposite to the door body air inlet 211, and the cold air generated in the cabinet 10 is blown to the door body 20 to absorb heat through the connection of the cabinet air inlet 121 and the door body air inlet 211. The cabinet air return 122 is opposite to the door body air return 212, and the hot air discharged from the door body 20 is returned through the connection of the cabinet air return 122 and the door body air return 212.

[0068] As shown in Figure 8 , the door body air inlet 211 and the door body air return 212 are arranged in the height direction of the door body 20.

[0069] The refrigerator 100 provided by the embodiments of the present application further includes a sealing device 30. The sealing device 30 is arranged on the cabinet air duct opening 12 and / or the door body air duct opening 21. The sealing device 30 is used for sealing the connection position of the cabinet air duct opening 12 and the door body air duct opening 21.

[0070] In some embodiments of the present application, the sealing device 30 is arranged on the cabinet air inlet 121, the cabinet air return 122, the door body air inlet 211 and the door body air return 212, so as to seal each air duct opening and improve the sealing effect. However, it is not limited thereto. In some other embodiments, the sealing device 30 can also be arranged on the cabinet air inlet 121 and the cabinet air return 122, or arranged on the door body air inlet 211 and the door body air return 212, or arranged on the cabinet air inlet 121 and the door body air return 212, or arranged on the door body air inlet 211 and the cabinet air return 122, so as to seal the connection position of the cabinet air inlet 121 and the door body air inlet 211, and the connection position of the cabinet air return 122 and the door body air return 212.

[0071] Figure 3 As shown in Figure 1 , a partially exploded structural schematic view of the door body of the refrigerator.

[0072] As shown in Figure 3As shown, the sealing device 30 includes a retaining ring 31 and a sealing ring 32. The retaining ring 31 is located on the side of the enclosure air duct opening 12 and / or the door air duct opening 21 facing away from the other. The sealing ring 32 is located on the side of the enclosure air duct opening 12 and / or the door air duct opening 21 facing the other. The sealing ring 32 is connected to the retaining ring 31, thereby fixing the sealing device 30 to the enclosure air duct opening 12 and / or the door air duct opening 21.

[0073] The sealing ring 32 is made of soft sealing material, such as rubber or silicone rubber.

[0074] A sealing device 30 is installed between the air duct opening 12 of the enclosure and the air duct opening 21 of the door. The sealing device 30 is fixed to the air duct opening 12 of the enclosure and the air duct opening 21 of the door by connecting the sealing ring 32 and the fixing ring 31.

[0075] like Figure 10 As shown, 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 box or the air duct 21 of the door.

[0076] Multiple airbags 33 are formed between the sealing ring 32 and the fixing ring 31. These airbags 33 surround the openings of the air duct 12 in the housing or the air duct 21 in the door, effectively isolating the air duct from the outside air, thus improving sealing performance and reducing cold air leakage. This helps stabilize the temperature on the door 20, ensuring a stable flow of cold air to the ice-making device, thereby improving ice-making efficiency and speed. Furthermore, the airbags 22 are positioned around the air duct openings, and the presence of gas within them further reduces heat exchange between the door 20 and the housing 10 due to the low thermal conductivity of gas. This results in high insulation, improved cooling effect on the door 20, and ultimately, increased efficiency of the ice-making device on the door.

Figure 5 for Figure 3 The second schematic diagram shows the structure of the fixing ring of the sealing device on the door. Figure 6 for Figure 3 One of the schematic diagrams of the sealing ring structure of the sealing device on the door shown. Figure 7 for Figure 3 The second schematic diagram shows the structure of the sealing ring of the sealing device on the door. Figure 8 for Figure 1 The diagram shows the structure of the refrigerator door. Figure 9 for Figure 8 The diagram shows a cross-sectional view of the door along AA. Figure 10 for Figure 9 An enlarged structural diagram of part B of the gate shown.

[0078] As shown in Figure 4 and Figure 7 In some embodiments of the present application, the fixed ring 31 is provided with a fixed part 311 on the side facing the sealing ring 32. The sealing ring 32 is provided with a matching part 321 on the side facing the fixed ring 31. The fixed part 311 and the matching part 321 are mutually buckled, thereby fixing the sealing device 30 on the cabinet air duct opening 12 and / or the door body air duct opening 21.

[0079] In this way, by buckling the fixed part 311 and the matching part 321, a more secure connection is provided, ensuring that the sealing ring 32 will not easily fall off or shift during use, thereby maintaining long-term stable sealing effect. The buckling structure makes the installation and disassembly of the sealing ring 32 more convenient, without the need for complex tools or processes, facilitating users or maintenance personnel to replace and maintain. At the same time, the buckling design can compensate for errors in the manufacturing and installation process to some extent, ensuring good cooperation between the sealing ring 32 and the fixed ring 31, further improving the sealing performance and ensuring the stability of the internal temperature of the refrigerator 100 and the improvement of energy efficiency.

[0080] In some embodiments of the present application, the fixed part 311 and the matching part 321 are arranged around the opening of the air duct. The fixed part 311 and the matching part 321 arranged around the opening provide uniform support and fixation, ensuring that the sealing ring 32 maintains consistent pressure distribution 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.

[0081] In some embodiments of the present application, one of the fixed part 311 and the matching part 321 is a buckle, and the other is a reverse buckle.

[0082] In this way, the cooperation of the buckle and the reverse buckle makes the connection between the sealing ring 32 and the fixed ring 31 more stable, reducing the risk of loosening or falling off. The cooperation of the reverse buckle and the buckle makes the installation process more intuitive and simple, usually only needs to be pressed lightly to achieve buckling, and can be completed without the aid of tools, reducing the installation time and complexity and improving the convenience of users. At the same time, the close combination of the buckle and the reverse buckle can effectively resist the vibration caused by the opening and closing of the refrigerator 100 door or other external factors, maintaining the stability of the sealing device 30. Because the cooperation of the buckle and the reverse buckle requires specific alignment and force, it can also prevent the sealing ring 32 and the fixed ring 31 from being misassembled or loosened to some extent, reducing the probability of user errors during installation.

[0083] Please also refer to Figure 10 In some embodiments of the present application, the fixed part 311 is a reverse buckle, the matching part 321 is a buckle, the opening of the cabinet air duct 12 and the door body air duct 21 is provided with an air duct plate 101, and the reverse buckle penetrates the air duct plate 101.

[0084] In this way, the reverse buckle passes through the air duct plate 101, providing additional support and fixation for the fixed 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 reverse buckling and buckling is more secure, further improving sealing performance, reducing cold air leakage, and improving the energy efficiency of the refrigerator 100. At the same time, the reverse buckle passing through the air duct plate 101 can help users more easily align the buckle position during installation, simplifying the installation steps and reducing installation errors.

[0085] Please also refer to Figure 5 In some embodiments of the present application, the fixed ring 31 further comprises an abutting part 312. The abutting part 312 is connected with the fixed part 311, and the abutting part 312 abuts with the side of the air duct plate 101 away from the sealing ring 32.

[0086] Along the radial direction of the opening of the cabinet air duct 12 and the door air duct 21, the abutting part 312 is arranged on the outer side of the fixed part 311.

[0087] In this way, the abutting part 312 provides additional support for the fixed ring 31, making the fixed ring 31 more stable when subjected to external forces, preventing the fixed ring 31 and the sealing ring 32 from shifting during use, ensuring the continuous effectiveness of the sealing device 30, and enhancing the strength and durability of the overall structure. The contact between the abutting part 312 and the air duct plate 101 provides a stable support surface, ensuring that the sealing ring 32 maintains good position and shape during use, thereby improving sealing reliability. At the same time, the design of the abutting part 312 helps to absorb and disperse vibrations caused 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.

[0088] Please also refer to Figure 6 and Figure 10 In some embodiments of the present application, the air bag 33 comprises an inner ring air bag 331, and the sealing ring 32 further comprises an inner flange 322. The inner flange 322 is connected with the matching part 321, and along the radial direction of the opening of the cabinet air duct 12 and the door air duct 21, the inner flange 322 is folded inward and abuts against the fixed part 311. The inner flange 322, the matching part 321 and the fixed part 311 form the inner ring air bag 331.

[0089] Along the radial direction of the opening of the cabinet air duct 12 and the door air duct 21, the inner flange 322 is arranged on the inner side of the matching part 321.

[0090] Thus, the design of the inward turning edge 322 makes the connection between the sealing ring 32 and the fixed part 311 more stable, reducing the displacement or deformation of the sealing ring 32 during use. The inner ring air bag 331 can provide flexible cushioning when the refrigerator 100 door is closed, reducing the direct impact on the sealing ring 32 and prolonging the service life of the sealing ring 32. The flexibility of the inner ring air bag 331 can also reduce the noise generated when the refrigerator 100 door is closed, providing a quieter use environment. The design of the inner ring air bag 331 provides an additional sealing layer that can more effectively prevent air and moisture leakage, improving the sealing performance and energy efficiency of the refrigerator 100.

[0091] Please also refer to Figure 5 In some embodiments of the present application, the fixed ring 31 further comprises a sealing part 313. The sealing part 313 is connected to the side of the fixed part 311 away from the abutting part 312. The inward turning edge 322 abuts the sealing part 313, and the sealing part 313, the inward turning edge 322, the fitting part 321 and the fixed part 311 form the inner ring air bag 331.

[0092] Along the radial direction of the cabinet air duct opening 12 and the door air duct opening 21, the sealing part 313 is arranged on the inner side of the fixed part 311.

[0093] Thus, the sealing part 313 provides an additional sealing interface for the inward turning edge 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 part 313 also improves the pressure resistance of the inner ring air bag 331, making the structure of the inner ring air bag 331 more stable and reducing the deformation of the inner ring air bag 331 when the pressure changes, thereby maintaining consistent sealing effect.

[0094] In some embodiments of the present application, the fixed part 311, the abutting part 312 and the sealing part 313 are all annular, thereby improving the stability of the structure and making the fixed ring 31 more stable when subjected to external force.

[0095] Please also refer to Figure 6 , Figure 7 and Figure 10 In some embodiments of the present application, the air bag 33 comprises an outer ring air bag 332. The sealing ring 32 further comprises an outward turning edge 323. The outward turning edge 323 is connected to the fitting part 321, and along the radial direction of the cabinet air duct opening 12 and the door air duct opening 21, the outward turning edge 323 is folded outward and abuts the air duct plate 101. The outward turning edge 323, the fitting part 321, the fixed part 311 and the air duct plate 101 form the outer ring air bag 332.

[0096] Along the radial direction of the cabinet air duct opening 12 and the door air duct opening 21, the outward turning edge 323 is arranged on the outer side of the fitting part 321.

[0097] 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 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, reducing wear and tear and improving the durability of the sealing device 30. The outer ring air bag 332 can better adapt to the pressure changes inside and outside the refrigerator 100, providing flexible cushioning when the refrigerator 100 door is closed, reducing direct impact on the sealing ring 32 and prolonging the service life of the sealing ring 32. The flexibility of the outer ring air bag 332 can also reduce the noise generated when the refrigerator 100 door is closed, providing a quieter use environment. The design of the outer ring air bag 332 provides an additional sealing layer, which can more effectively prevent air and moisture leakage, improving the sealing performance and energy efficiency of the refrigerator 100.

[0098] At the same time, the combination of the inner ring air bag 331 and the outer ring air bag 332 forms a double-sealing structure, with the inner ring air bag 331 preventing cold air from flowing out of the air duct and the outer ring air bag 332 preventing air from flowing into the air duct, significantly improving the sealing performance of the sealing ring 32 and the heat preservation performance of the refrigerator 100, reducing energy loss.

[0099] In some embodiments of the present application, the sealing ring 32 further comprises a sealing edge 324. The sealing edge 324 is connected to the side of the outwardly turned edge 323 away from the fitting part 321, and the sealing edge 324 abuts the side of the air duct plate 101 away from the fixing ring 31. The sealing edge 324, the outwardly turned edge 323, the fitting part 321, the fixing part 311 and the air duct plate 101 form the outer ring air bag 332.

[0100] In this way, the addition of the sealing edge 324 provides an additional sealing interface for the outwardly turned edge 323, which, in combination with the outwardly turned edge 323 and the air duct plate 101, further improves the sealing performance of the sealing ring 32 and ensures more effective prevention of air and moisture leakage. The abutment of the sealing edge 324 with the air duct plate 101 provides additional support and stability for 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 allows the outer ring air bag 332 to better disperse and absorb external pressure and impact force, enhancing the pressure resistance and impact resistance of the sealing device 30.

[0101] In some embodiments of the present application, the sealing edge 324 extends towards the fitting part 321 along the radial direction of the cabinet air duct opening 12 and the door air duct opening 21, thereby reducing the gap between the outer ring air bag 332 and the air duct plate 101 and improving the sealing effect.

[0102] In some embodiments of the present application, the fixing part 311 is provided with a first undercut 314 and a second undercut 315. The matching part 321 is provided with a first buckle 325 and a second buckle 326. The first undercut 314 and the second undercut 315 are oppositely arranged along the radial direction of the box air duct opening 12 and the door air duct opening 21. The first undercut 314 is buckled connected with the first buckle 325, and the second undercut 315 is buckled connected with the second buckle 326.

[0103] In this way, by using the combination of two undercuts and two buckles, the connection is more stable, ensuring that the sealing ring will not easily loosen or fall off during use, maintaining the performance stability of the sealing device. The design of double undercuts and buckles provides more uniform pressure distribution, which helps to improve the sealing effect of the sealing ring and reduce air and moisture leakage. The design of double buckles also helps to align and fix more easily during installation, simplifying the installation steps and reducing the possibility of errors.

[0104] In some embodiments of the present application, the first undercut 314 and the second undercut 315 are provided with multiple. Multiple first undercuts 314 and multiple second undercuts 315 are arranged in sequence around the circumferential direction of the box air duct opening 12 and the door air duct opening 21 opening.

[0105] Optionally, the first undercut 314 and the second undercut 315 are arranged at intervals around the circumferential direction of the box air duct opening 12 and the door air duct opening 21 opening, thereby improving the stability of the buckling connection between the fixing part 311 and the matching part 321.

[0106] Optionally, the first undercut 314 and the second undercut 315 are uniformly arranged around the circumferential direction of the box air duct opening 12 and the door air duct opening 21 opening.

[0107] In some embodiments of the present application, the first buckle 325 and the second buckle 326 are oppositely arranged on the matching part 321, and the first buckle 325 and the second buckle 326 are annular around the circumferential direction of the box air duct opening 12 and the door air duct opening 21 opening, respectively.

[0108] The annular first buckle 325 and the second buckle 326 can reduce the connection difficulty of the buckling connection between the first undercut 314 and the first buckle 325, and the buckling connection between the second undercut 315 and the second buckle 326, facilitating the user to install and fix. The annular first buckle 325 and the second buckle 326 can also improve the stability of the buckling connection between the first undercut 314 and the first buckle 325, and the buckling connection between the second undercut 315 and the second buckle 326, thereby fixing the sealing device 30 on the box air duct opening 12 and the door air duct opening 21.

[0109] The refrigerator 100 provided in the application comprises a cabinet 10, a door body 20, an ice making device and a sealing device 30. The cabinet 10 is internally formed with a storage chamber 11, and the inner wall surface of the storage chamber 11 is provided with a cabinet air duct opening 12. The door body 20 is rotatably arranged on the cabinet 10, and is used to close the opening of the storage chamber 11. The position of the door body 20 relative to the cabinet air duct opening 12 is provided with a door body air duct opening 21. The ice making device is arranged on the door body 20, and is in communication with the door body air duct opening 21. When the door body 20 closes the opening of the storage chamber 11, the cabinet air duct opening 12 and the door body air duct opening 21 are in abutment. The sealing device 30 is arranged on the cabinet air duct opening 12 and / or the door body air duct opening 21, so as to seal the abutment position of the cabinet air duct opening 12 and the door body air duct opening 21 when the cabinet air duct opening 12 and the door body air duct opening 21 are in abutment. The sealing device 30 comprises a fixing ring 31 and a sealing ring 32. The fixing ring 31 is arranged on the side of the cabinet air duct opening 12 and / or the door body air duct opening 21 away from the other. The sealing ring 32 is arranged on the side of the cabinet air duct opening 12 and / or the door body air duct opening 21 facing the other. The sealing ring 32 is connected with the fixing ring 31. A plurality of air bags 33 are formed between the fixing ring 31 and the sealing ring 32, and the plurality of air bags 33 are arranged around the opening of the cabinet air duct opening 12 or the door body air duct opening 21.

[0110] In this way, the sealing device 30 is arranged between the cabinet air duct opening 12 and the door body air duct opening 21. The sealing device 30 comprises the sealing ring 32 and the fixing ring 31. The sealing device 30 is fixed on the cabinet air duct opening 12 and the door body air duct opening 21 through the connection of the sealing ring 32 and the fixing ring 31. A plurality of air bags 33 are formed between the sealing ring 32 and the fixing ring 31, and the plurality of air bags 33 are arranged around the opening of the cabinet air duct opening 12 and the door body air duct opening 21. The air bags 33 can effectively cut off the circulation of the air duct and the air outside the air duct, thereby improving the sealing performance and reducing the cold air leakage. This helps to improve the stability of the temperature on the door body 20 and ensures that the ice making device can obtain stable cold air flow, thereby improving the ice making efficiency and speed. Moreover, the air bags 33 are arranged around the opening of the air duct, and there is gas in the air bags 33. Since the heat conduction efficiency of the gas is low, the heat exchange between the door body 20 and the cabinet 10 is further reduced, the heat preservation effect is high, the refrigeration effect on the door body 20 is improved, and the efficiency of the ice making device on the door is improved.
