Description

Technical Field

[0001] The utility model relates to the field of refrigerator door sealing, and more specifically to a refrigerator door sealing structure and a refrigerator. Background Art

[0002] Most traditional beauty refrigerator door seals use soft EVA strips to achieve sealing. This kind of sealing strip has poor elasticity and is not easy to rebound after being compressed, resulting in poor sealing effect, easy cold leakage at the sealing point, and reduced product performance. In addition, condensation water will be generated at the poorly sealed place. When the condensation water accumulates to a certain amount, it will flow onto the desktop or the floor, causing inconvenience to the user. Therefore, in order to improve the sealing performance, a door seal structure with better sealing performance is required. For example, Chinese patent No. CN215892932U discloses a refrigerator door seal and a refrigerator. The refrigerator door seal includes: a mounting portion, which is used to mount the door seal to the door body of the refrigerator; an airbag portion, which is connected to one side of the mounting portion and is used to form an airtight seal between the door body and the refrigerator body; a supporting vertical beam, which is arranged in the airbag portion, and is formed by extending from the inner surface of the airbag portion away from the mounting portion to the inner surface of the airbag portion close to the mounting portion; a wing, which is arranged on both sides of the outer surface of the airbag portion away from the mounting portion, and is inclined toward the mounting portion. Although this prior art uses side wings to better fit the door body and improve the sealing effect, the door seal has a complex structure, dust easily accumulates at the bottom of the side wings, and it is inconvenient to clean. In addition, only a single door seal is used for sealing, which has limited improvement in the sealing effect. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a refrigerator door sealing structure and a refrigerator, which can enhance the sealing performance and improve the heat preservation effect.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A refrigerator door seal structure is arranged at the closing part of the box body and the door body of the refrigerator, and the box body and the door body are both embedded with magnets corresponding to each other at one end of the closing part. The refrigerator door seal structure includes a first door seal and a second door seal arranged on the end surface of the door body, and a convex rib arranged on the end surface of the box body. The tops of the first door seal and the second door seal are both arc-shaped structures, and the convex rib corresponds to the vertex position of the first door seal; the second door seal is away from the inside of the box body relative to the first door seal, and the second door seal is higher than the first door seal, and the height difference between the second door seal and the first door seal is equal to the deformation of the first door seal when the box body and the door body are closed.

[0006] The technical solution provides a refrigerator door seal structure, which increases the difficulty of cold air flowing out of the outside of the box by adopting a double-layer door seal structure, thereby enhancing the sealing, improving the thermal insulation effect, and preventing the generation of condensation water; at the same time, the above structure only needs to use convex ribs and two door seals to achieve door sealing, and the structure is simple and easy to install. In addition, since the tops of the first door seal and the second door seal are both arc-shaped structures, dust is not easy to accumulate, and it is easy to clean and maintain.

[0007] In a preferred technical solution, the first door seal and the second door seal are both hollow structures, and the low thermal conductivity of air is used to slow down the cold conduction speed, thereby achieving a better thermal insulation effect.

[0008] In a preferred technical solution, the height of the convex rib is not less than 1.5 mm to ensure that the first door seal is sufficiently deformed, extend the distance of the cold air flow to the outside of the box, and further enhance the sealing.

[0009] In a preferred technical solution, the cross-sectional size of the convex rib is 1.5 mm×1 mm, which is used to ensure sufficient deformation of the first door seal and is easy to manufacture.

[0010] In a preferred technical solution, the first door seal and the second door seal are both made of foam rubber, which is soft and highly resilient and can rebound when compressed, thereby achieving a better sealing effect.

[0011] A refrigerator comprises a refrigerator door sealing structure as in any of the above technical solutions.

[0012] The refrigerator in the present technology adopts the above-mentioned refrigerator door sealing structure. By adopting a double-layer door sealing structure, it is possible to increase the difficulty of cold air flowing out of the box body, thereby enhancing the sealing and improving the refrigeration effect.

[0013] It can be seen from the above technical solution that compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides a refrigerator door seal structure, which forms three sealed spaces through two layers of door seals, which increases the difficulty of cold air flowing out of the outside of the box, thereby enhancing the sealing, improving the insulation effect, and preventing the generation of condensation water. At the same time, its structure is simple, dust is not easy to accumulate, and it is easy to install and maintain. A refrigerator adopts the above refrigerator door seal structure, which can enhance the airtightness, improve the insulation effect, and is not easy to accumulate dust and easy to maintain.

[0022] Reference Figure 1-2 A refrigerator door sealing structure and a refrigerator according to an embodiment of the utility model are described.

[0023] In one embodiment, Figure 1As shown, a refrigerator door seal structure is arranged at the closing part of the box body 10 and the door body 20 of the refrigerator, and the box body 10 and the door body 20 are both embedded with magnets 4 corresponding to each other at one end of the closing part, including a first door seal 1 and a second door seal 2 arranged on the end surface of the door body 20, and a convex rib 3 arranged on the end surface of the box body 10, the tops of the first door seal 1 and the second door seal 2 are both arc-shaped structures, and the convex rib 3 corresponds to the vertex position of the first door seal 1; the second door seal 2 is away from the inside of the box body 10 relative to the first door seal 1, and the second door seal 2 is higher than the first door seal 1, and the height difference between the second door seal 2 and the first door seal 1 is equal to the deformation of the first door seal 1 when the box body 10 and the door body 20 are closed.

[0024] Among them, a first magnet 4 is embedded in the end where the box body 10 and the door body 20 are closed, and a second magnet 4 corresponding to the first magnet 4 is embedded in the door body 20; the deformation of the first door seal 1 when the box body 10 and the door body 20 are closed, that is, the deformation of the first door seal 1 caused by the compression of the box body 10 and the door body 20 when they are closed under the attraction of the magnet 4.

[0025] As an implementation method of this embodiment, two parallel grooves are provided on the end surface of the door body 20 from the inside to the outside, and the first door seal 1 and the second door seal 2 are respectively installed in the two grooves. Among them, both door seals are an integrally formed structure, which is composed of an arc-shaped elastic deformation part at the upper end and a rectangular installation part at the lower end. The installation part is used to fix the door seal in the groove, and the elastic deformation part is used to deform under the pressure of the end surface of the box body 10 to fit closely to the box body 10 to enhance the sealing performance.

[0026] When implementing it, Figure 2 As shown, when the box body 10 and the door body 20 are attracted by the magnet, the convex rib 3 is pressed into the top of the first door seal 1 to deform the first door seal 1. At the same time, under the suction of the magnet 4, the end face of the box body 10 also squeezes the first door seal 1 and the second door seal 2, so that the two layers of door seals are tightly attached to the end face of the box body 10, thereby achieving a double-layer insulation effect. Among them, the second door seal 2 is higher than the first door seal 1, so that when the box body 10 presses the two layers of door seals, the second door seal 2 fits more closely to the end face of the box body 10, which is conducive to enhancing the sealing performance.

[0027] In this embodiment, the refrigerator door seal structure adopts a double-layer door seal structure. After the magnets 4 on the box body 10 and the door body 20 are attracted, the two layers of door seals can be tightly attached to the front of the box body 10. The cold air inside the box body 10 flows to the outside of the box body 10. It needs to first pass through the first door seal 1, then pass through the closed space formed by the first door seal 1 and the second door seal 2 attached to the front of the box body 10, and finally flow through the second door seal 2 to flow to the outside of the box body 10. The direction of the cold air flow is Figure 2The two-layer door seal forms three sealed spaces, which increases the difficulty of cold air flowing out of the box body 10, thereby enhancing the sealing performance, improving the heat preservation effect, and preventing condensation water from being generated.

[0028] At the same time, the above structure only needs to use the convex rib 3 and two door seals to achieve door sealing, the structure is simple and easy to install. Since the tops of the first door seal 1 and the second door seal 2 are both arc-shaped structures, dust is not easy to accumulate, and it is easy to clean and maintain.

[0029] In this embodiment, the first door seal 1 and the second door seal 2 are both hollow structures.

[0030] In the above embodiment, both layers of door seals adopt a hollow structure. The cold air in the box 10 first passes through one side wall of the door seal, then enters the enclosed air with low thermal conductivity in the door seal cavity, and finally passes through the outer wall of the door seal to the outside of the box 10. The low thermal conductivity of the air can be utilized to slow down the speed of cold conduction, thereby achieving a heat preservation effect and preventing the formation of condensation water.

[0031] In this embodiment, the height of the convex rib 3 is not less than 1.5 mm. In this embodiment, the convex rib 3 corresponds to the highest point of the first door seal 1. Under the suction of the magnet 4, when the convex rib 3 presses against the top of the first door seal 1, the first door seal 1 is deformed into a convex rib 3 wall that is close to the end surface of the box body 10, which prolongs the distance of the cold air flow to the outside, enhances the sealing of the box body 10, and thus achieves a better insulation effect.

[0032] In this embodiment, the cross-sectional dimensions of the rib 3 are 1.5 mm×1 mm, which is used to ensure sufficient deformation of the first door seal and is easy to manufacture.

[0033] In this embodiment, the first door seal 1 and the second door seal 2 are both made of foam rubber.

[0034] In the above embodiment, since the foam rubber material has the advantages of being soft and having strong resilience, it is easy to rebound after being compressed, which can further ensure the sealing of the refrigerator.

[0035] In another embodiment, the utility model provides a refrigerator, which includes a refrigerator door sealing structure as in any of the above embodiments.

[0036] The above-mentioned refrigerator box adopts a double-layer door sealing structure, which can increase the difficulty of cold air flowing out of the outside of the box body 10, thereby enhancing the sealing performance and improving the refrigeration effect.

[0037] The door sealing structure of the refrigerator box according to the embodiment of the utility model and other structures and operations of the refrigerator box are known to ordinary technicians in the field and will not be described in detail here.
