There is air convection inside the door seals, and long-term use and pressing of the door seals will cause the door seals to lose elasticity, thereby affecting the energy consumption of the refrigeration equipment. Summary of the Utility Model

[0019] A door seal body, and the door seal body includes:

[0020] A clamping part, used for cooperating with the clamping groove for clamping;

[0021] A plurality of air bags, arranged on the side of the clamping part away from its tip, for being extruded and deformed to fit and seal with the surface of the box body;

[0034] The following will describe in detail the specific implementation manner of the embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific implementation manner described herein is only used to illustrate and explain the embodiments of the present utility model, and is not used to limit the embodiments of the present utility model.

[0035] Figure 1 It is a schematic structural diagram of a wrapped door seal structure of a refrigeration device according to an embodiment of the present utility model. In Figure 1 this, the wrapped door seal structure may include a door seal body 3 and a strip-shaped filler 4. Specifically, the door seal body 3 may include a clamping portion 1 and a plurality of air bags 2.

[0036] The clamping portion 1 is used to cooperate with the clamping groove 9 of the door 8 for clamping. The plurality of air bags 2 are arranged on the side of the clamping portion 1 away from its tip. Specifically, the clamping portion 1 is triangular in shape, so it is the bottom side of the clamping portion 1. The plurality of air bags 2 are used to be squeezed and deformed to fit and seal with the surface of the cabinet 7. The strip-shaped filler 4 is filled inside the air bag 2 close to the clamping portion 1.

[0037] When installing this door seal structure, the clamping portion 1 of the door seal body 3 can be cooperatively clamped with the clamping groove 9. When the door 8 is closed, the plurality of air bags 2 are squeezed so that the plurality of air bags 2 can closely fit with both the cabinet 7 and the door 8 to seal between the cabinet 7 and the door 8. When the air bags 2 are squeezed, the strip-shaped filler 4 filled inside is also squeezed and deformed synchronously, but still remains in the state of being filled inside the air bags 2. When the strip-shaped filler 4 is squeezed, its filling degree is further improved, thereby effectively reducing the convection of the gas inside the air bags 2.

[0038] The door seals of traditional refrigeration devices such as refrigerators are multi-air bag structures, and the door seals of freezers are mostly single-air bag structures. There is air convection inside the door seals, and long-term use of pressing the door seals will cause the door seals to lose elasticity, thereby affecting the energy consumption of the refrigeration devices. In this embodiment of the present utility model, by using the method of filling the strip-shaped filler 4 inside the air bag 2 close to the clamping portion 1, the convection of the gas inside the air bag 2 can be effectively reduced, that is, the heat conduction inside the air bag 2 is effectively reduced, thereby improving the heat preservation effect of the door seal body 3 and reducing the energy consumption of the refrigeration device. At the same time, the strip-shaped filler 4 can also support the air bag 2 to maintain the maximum deformation amplitude of the air bag 2 and ensure the reset effect of the air bag 2.

[0039] In this embodiment of the present utility model, the airbag 2 can include various forms known in the art, such as a magnetic strip bag, a main airbag, an auxiliary airbag, etc. Specifically, the strip-shaped filler 4 is arranged inside the airbag 2 close to the clamping portion 1, that is, inside the main airbag 2. On the one hand, it can improve the reset elasticity of the main airbag 2, and on the other hand, it can effectively reduce the gas convection inside the door seal body 3.

[0040] In this embodiment of the present utility model, the specific form of the strip-shaped filler 4 can include a low thermal conductivity material. Specifically, the strip-shaped filler 4 can include felt, etc. Specifically, the felt material has a low thermal conductivity and does not melt with the extruded door seal body 3. It can be taken out and separated after being formed with the door seal body 3, so it has stronger versatility and wider applicability. In addition, the felt material can fill the inside of the door seal body 3. In a steady state, it eliminates the internal gas convection and reduces the heat conduction. At the same time, the material of the felt is a low thermal conductivity material with a low thermal conductivity, which also reduces the heat mass transfer and improves the heat preservation performance of the door seal. When the door is closed, the felt material can be deformed synchronously under force so that the door seal can stably fit on the box body 7 without interfering with the deformation of the door seal.

[0041] In this embodiment of the present utility model, as Figure 1 shown, the corner of the airbag 2 close to the box body 7 in the door seal assembly is provided with an arc 5, that is, the edge where the airbag 2 fits the box body 7 is provided with an arc 5. Specifically, on the one hand, the arc 5 structure can avoid the door edge being twisted when the door body 8 is closed, and on the other hand, it can also make the door seal fit the box body 7 better.

[0042] In this embodiment of the present utility model, as Figure 1 shown, the airbag 2 can include two thickening parts 6. Specifically, the thickening parts 6 are arranged on the inner wall of the main airbag 2.

[0043] The inner wall of the airbag 2 close to the clamping portion 1 is provided with thickening parts 6, and the thickening parts 6 are arranged on two side walls adjacent to the connection side of the airbag 2 and the clamping portion 1.

[0044] The inner walls of the two sides adjacent to the side of the main airbag 2 close to the door body 8 are provided with thickening parts 6, and the thickening parts 6 can effectively improve the pressing and supporting characteristics of the door seal, thereby improving the service life of the door seal.

[0045] In this embodiment of the present utility model, the thickness of the thickening gradually increases from the box body 7 end along the thickness of the door body 8 end to further improve the stability and supporting effect of the airbag 2 being pressed.

[0046] On the other hand, the present utility model also provides a refrigeration device. Specifically, as Figure 1As shown, the refrigeration device may include a box body 7, a door body 8, and a wrapped door seal structure. Specifically, the box body 7 may include an opening and a refrigeration device, and the door body 8 may include a clamping groove 9.

[0047] An opening is provided on one side of the box body 7, and a refrigeration device is provided inside the box body 7. The door body 8 is provided on the opening side of the box body 7 and is connected to the box body 7. A clamping groove 9 is provided on the side of the door body 8 close to the box body 7. The wrapped door seal structure is provided between the box body 7 and the door body 8 for sealing between the box body 7 and the door body 8 and reducing gas convection.

[0048] The refrigeration device is placed inside the box body 7 to cool the inside of the box body 7.

A plurality of air bags 2 are provided on the side of the clamping portion 1 away from its tip. Specifically, the clamping portion 1 is triangular in shape, so that is, the bottom side of the clamping portion 1. The plurality of air bags 2 are used to be squeezed and deformed to fit and seal with the surface of the box body 7. The strip-shaped filler 4 is filled inside the air bag 2 close to the clamping portion 1.

[0051] When installing the door seal structure, the clamping portion 1 of the door seal body 3 can be clamped with the clamping groove 9. When the door body 8 is closed, the plurality of air bags 2 are squeezed so that the plurality of air bags 2 can closely fit with both the box body 7 and the door body 8 to seal between the box body 7 and the door body 8. When the air bag 2 is squeezed, the strip-shaped filler 4 filled inside is also squeezed and deformed, but still remains in a state of being filled inside the air bag 2. When the strip-shaped filler 4 is squeezed, its filling degree is further improved, thereby effectively reducing the gas convection inside the air bag 2.

[0052] In this embodiment of the present invention, the air bag 2 may include various forms known in the art, such as a magnetic strip bag, a main air bag, an auxiliary air bag, etc. Specifically, the strip-shaped filler 4 is provided inside the air bag 2 close to the clamping portion 1, that is, inside the main air bag 2.

[0053] In this embodiment of the present utility model, the specific form of the strip-shaped filler 4 may include a low thermal conductivity material. Specifically, the strip-shaped filler 4 may include felt, etc. Specifically, the felt material has a low thermal conductivity and does not melt with the extruded door seal body 3, and can be taken out and separated after being formed with the door seal body 3, so it has stronger versatility and wider applicability. In addition, the felt material can fill the inside of the door seal body 3. In a steady state, it eliminates internal gas convection and reduces heat conduction. At the same time, the material of the felt is a low thermal conductivity material with a low thermal conductivity, which also reduces heat mass transfer and improves the heat preservation performance of the door seal. When the door is closed, the felt material can be deformed synchronously under force, so that the door seal can stably fit on the box body 7 without interfering with the deformation of the door seal.

[0054] In this embodiment of the present utility model, as Figure 1 shown, the corner of the airbag 2 close to the box body 7 in the door seal assembly is provided with an arc 5, that is, the edge where the airbag 2 fits the box body 7 is provided with an arc 5.
