[0002] With rising energy efficiency standards, reducing the energy consumption of refrigerators, as continuously operating household appliances, has become a key focus for manufacturers. Optimizing the door seal structure is one of the key means to improve refrigerator sealing performance and energy efficiency.
[0003] Traditional door seals are often made of rubber or silicone, which achieve a seal between the door and the refrigerator body through compression deformation. Over time, these seals are prone to aging and deformation, leading to a decrease in sealing performance, which in turn affects the refrigerator's insulation and energy efficiency. While airbag door seals offer some improvements over traditional door seals in terms of improved sealing performance and energy savings, they still have the following drawbacks.
[0004] Existing airbag door seal designs are often simplistic. Firstly, they lack sufficient deformation and adaptability, making it difficult to maintain a stable seal even when the door is closed with varying force and angles. This is especially true after prolonged use or external impact, where the airbag can easily deform or damage, resulting in a decrease in sealing performance. Furthermore, their thermal insulation design is inadequate, failing to effectively block heat conduction paths. This is especially true when the contact area between the airbag and the refrigerator body or door is limited or loose, impacting the refrigerator's insulation and energy efficiency.
[0005] Therefore, developing a new door seal structure, optimizing the airbag layout, enhancing deformation ability, improving thermal insulation effect, and achieving energy saving and consumption reduction has important market value and social significance. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings.
[0028] like Figure 1 and Figure 2 As shown, this embodiment provides an open-type airbag door sealing structure, which is placed between the refrigerator body 1 and the door body 2. A groove 21 is provided on the door body 2 of the refrigerator. The open-type airbag door sealing structure includes a crossbeam 4, an airbag part 3 and a fastener 5. The bottom of the airbag part 3 is connected to the crossbeam 4, and the fastener 5 is located below the crossbeam 4. The fastener 5 is arrow-shaped as a whole, wherein the bottom of the arrow is connected to the crossbeam 4, and the top of the arrow is buckled in the above-mentioned groove 21 and abuts against the inner wall of the groove 21 to fix the door sealing structure on the door body 2.
[0029] The crossbeam 4, the airbag part 3 and the fastener 5 are an integral part. The crossbeam 4 is used to firmly support the airbag part 3 and the fastener 5, which can enhance the door seal stiffness to cope with longitudinal pressure. The airbag part 3 acts as an insulation barrier, effectively blocking the internal and external heat transfer, thereby achieving a sealing and heat insulation effect. The fastener 5 ensures that the door seal structure is firmly installed on the door body 2.
[0030] The airbag portion 3 is fixed to the door body 2 and thus moves synchronously along the closing trajectory of the door body 2. Specifically, Figure 1 and Figure 2As shown, the airbag portion 3 includes a magnetic stripe bag 31, a first airbag 32, a second airbag 33, a square chamber 34, a third airbag 35, an airbag tail wing 36 and a long airbag 37. One side of the first airbag 32 is connected to the magnetic stripe bag 31, and an airbag tail wing 36 is provided on the upper part of the other side of the first airbag 32. When the door body 2 is closed, the airbag tail wing 36 fits with the box body 1, and the lower part of the other side of the first airbag 32 is connected with the long airbag 37. The long airbag 37 has a "b" type structure. One end of the long airbag 37 is connected to the first airbag 32, and the other end is a closed air chamber. The long airbag 37 fits on the door body 2 and its length does not exceed the door body 2. When the door body 2 is rotated and closed, the door Under the attraction force of the magnetic force, the sealing structure is adsorbed on the box body 1, the airbag part 3 is squeezed and deformed, the airbag tail wing 36 contacts the long airbag 37 to form an air chamber 38, and at the same time the long airbag 37 will be inserted into the gap between the door body 2 and the box body 1 along the closing trajectory and contact the box body 1. The above-mentioned air chamber 38 can switch between opening and closing with the movement of the door body 2. The second airbag 33, the square chamber 34 and the third airbag 35 are distributed below the magnetic strip bag 31 and the first airbag 32. The second airbag 33 and the third airbag 35 are connected, the square chamber 34 is placed at the bottom of the second airbag 33, and the bottom of the second airbag 33, the square chamber 34 and the third airbag 35 are connected to the crossbeam 4.
[0031] The airbag portion 3 will deform when subjected to the closing force of the door body 2 and the box body 1, wherein the magnetic strip bag 31 is used to accommodate the magnetic strip, so that when the door body 2 is closed, it provides a strong adsorption force, so that the door body 2 and the box body 1 fit tightly together, and the elastic deformation of the first airbag 32 can play a buffering role, reducing the impact force when the door body 2 is closed. At the same time, since the first airbag 32 is designed to be arc-shaped on the side close to the door body 2, it can be more easily compressed and deformed during the closing process of the door body 2, thereby avoiding excessive gaps between the door seal and the box body 1 and achieving better sealing effect. During the closing and opening process of the door body 2, the second airbag 33 needs to withstand tensile and compressive deformations. This deformation ability makes The door sealing structure can adapt to the movement of the door body 2 and maintain a stable sealing effect. At the same time, the deformation of the second airbag 33 also helps to fill the tiny gap between the door body 2 and the box body 1, further improving the sealing performance. The square chamber 34 arranged at the bottom of the second airbag 33 increases the connection strength inside the airbag part 3, so that the entire airbag part 3 can maintain structural stability and integrity when subjected to external force. The third airbag 35 is designed to fit closely to the bladder surface of the door body 2, which can ensure that it fits closely with the bladder surface when the door body 2 is closed, reducing heat conduction and improving the thermal insulation effect. The square chamber 34, the second airbag 33 and the third airbag 35 constitute multiple independent isolation air chambers, which can effectively isolate the exchange of internal and external gases and improve thermal insulation performance.
[0032] In addition, the design of the airbag tail wing 36 increases the contact area with the box body 1, effectively extends the heat transfer path, and reduces the heat transfer efficiency. The "b" type structural design of the long airbag 37 enables it to be more easily deformed and fit on the surface of the door body 2 when squeezed, thereby enhancing the sealing effect. During the closing process of the door body 2, the airbag tail wing 36 contacts the long airbag 37 and forms a new air chamber 38. At the same time, the long airbag 37 will be inserted into the gap between the door body 2 and the box body 1 along the closing trajectory and fit tightly with the box body 1. The above-mentioned air chamber 38 works together with the closed air chamber in the long airbag 37 to further isolate the exchange of internal and external gases, reduce heat transfer, and achieve energy-saving sealing.
[0033] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
