Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator door seals, in particular to a refrigerator and an anti-twisting edge door seal structure thereof. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature and has been widely used in people's lives. The refrigeration effect of a refrigerator is determined by its internal refrigeration system on the one hand and the heat preservation performance of the refrigerator on the other. Therefore, the sealing structure of the refrigerator is also very important to maintain the refrigeration effect inside the refrigerator.

[0003] At present, in some refrigerator products, the distance between the door boxes after the refrigerator door is closed varies greatly. If an ordinary door seal structure is installed, when encountering a refrigerator with a small distance between the door boxes, the door seal edge is prone to twisting, resulting in poor sealing of the refrigerator, cold leakage, and increased energy consumption. In the prior art, the above-mentioned twisting edge problem is generally solved by reducing the height of the door seal airbag. However, when encountering a refrigerator with a large distance between the door boxes, this door seal structure is prone to flashing, which in turn causes the refrigerator to leak cold. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem that the prior art cannot be universally applied to situations where the distances between door boxes vary greatly, and to provide a refrigerator and a door sealing structure thereof with an anti-twisting edge, wherein the refrigerator and the door sealing structure thereof with an anti-twisting edge have the function of adapting to the use of refrigerators where the distances between door boxes vary greatly.

[0005] In order to achieve the above-mentioned object, the utility model provides, on one hand, a door sealing structure for a refrigerator with an anti-twisting edge, comprising:

[0006] An adsorption part, used for adsorption connection with the refrigerator body;

[0007] A first air bag is arranged below the adsorption part;

[0008] a second airbag, arranged above and to the right of the first airbag, wherein a partition is arranged in the second airbag, and the partition partitions the second airbag into a first air chamber and a second air chamber which are arranged vertically, and the right bottom of the second air chamber is concave inward;

[0009] The assembly part is arranged below the first airbag and the second airbag, and is used for engaging with the assembly groove on the door body of the refrigerator.

[0010] Optionally, a connecting portion is provided on a side wall of the first air chamber away from the adsorption portion, and an auxiliary airbag is provided on an end of the connecting portion away from the first air chamber.

[0011] Optionally, the top of the first air chamber is arranged to be inclined upward from left to right.

[0012] Optionally, the adsorption unit includes:

[0013] Magnetic strip capsule;

[0014] The first protrusion is arranged on the inner wall of the magnetic stripe bag.

[0015] Optionally, the upper left corner of the magnetic stripe capsule is arranged in an arc shape.

[0016] Optionally, the assembly portion includes:

[0017] A transverse connecting portion, arranged at the bottom of the first airbag and the second airbag;

[0018] The clamping portion is arranged at the bottom of the transverse connecting portion.

[0019] Optionally, an extension portion is provided at the tip of the clamping portion.

[0020] Optionally, sealing parts are provided at both ends of the transverse connecting part.

[0021] Optionally, the left side and the right side of the first airbag are both C-shaped.

[0022] On the other hand, the utility model also provides a refrigerator, comprising:

[0023] A refrigerator body, the refrigerator body comprising a box body and a door body, and a mounting groove is provided on a side of the door body close to the box body;

[0024] A door sealing structure as described above.

[0025] Through the above technical scheme, the refrigerator and its anti-twisting edge door sealing structure provided by the utility model can realize the installation of the door sealing structure by clamping the assembly part in the assembly groove on the door body. When the adsorption part is adsorbed and connected to the box body, when the distance between the box body and the door body is large, the first airbag provides distance compensation so that the first air chamber of the second airbag can be close to the box body to avoid problems such as flashing seams; when the distance between the box body and the door body is small, the box body squeezes the second airbag, and the inward depression of the right bottom of the second air chamber cooperates with the door body to form a makeshift space for the deformation of the second airbag, preventing the overall deviation of the door sealing structure and effectively avoiding the occurrence of problems such as twisting edges. Therefore, the door sealing structure can be suitable for refrigerators with different door-box distances, with stronger versatility and good sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0041] Figure 1 It is a structural schematic diagram of a door sealing structure for a refrigerator with an anti-twisting edge according to one embodiment of the utility model; Figure 2 This is a schematic diagram of a refrigerator door seal structure with an anti-twisting edge according to an embodiment of the present invention when in use. Figure 1 and Figure 2 In the embodiment, the door sealing structure may include an adsorption portion 3, a first airbag 4, a second airbag 8 and an assembly portion 11. Specifically, the second airbag 8 may include a first air chamber 5, a partition portion 6 and a second air chamber 7.

[0042] The adsorption portion 3 is used for adsorption connection with the refrigerator body 19, and the first airbag 4 is arranged below the adsorption portion 3. The second airbag 8 is arranged above and to the right of the first airbag 4. The second airbag 4 is provided with a partition 6, which divides the second airbag 8 into a first air chamber 5 and a second air chamber 7 which are distributed up and down. The right bottom of the second air chamber 7 is recessed inward 16. Specifically, the recess 16 can also be understood as the right part of the second air chamber 7 forming an arc extending to the left from the upper right to the lower right. The assembly portion 11 is arranged below the first airbag 4 and the second airbag 8, and is used to cooperate with the assembly groove 18 on the door body 17 of the refrigerator.

[0043] When the door sealing structure is needed, first fit the assembly portion 11 with the assembly groove 18 on the door body 17 to achieve the installation of the door sealing structure. When the distance between the box body 19 and the door body 17 is large, when the door body 17 is closed, the adsorption portion 3 is adsorbed with the side wall of the box body 19, the first airbag 4 can provide distance compensation, and the first air chamber 5 of the second airbag 8 is in close contact with the box body 19 to achieve the sealing of the door body 17 and the box body 19. When the distance between the box body 19 and the door body 17 is small, when the door body 17 is closed, the adsorption portion 3 is adsorbed with the side wall of the box body 19, the door sealing structure will contact the box body 19 and generate friction, that is, it will squeeze the second airbag 8. Due to the presence of the dividing portion 6, the door sealing structure can remain stable as a whole, avoid large displacement of the upper surface of the sealing structure due to friction, and prevent the overall displacement of the door sealing structure from causing deformation. At the same time, the inward recess 16 at the right bottom of the second air chamber 7 cooperates with the step of the door body 17 to form a clearance space. When the box body 19 squeezes the second airbag 8, the right part of the second air chamber 7 of the second airbag 8 is deformed in the clearance space, further avoiding the overall offset and deformation of the door sealing structure.

[0044] In the traditional door seal structure, when encountering a refrigerator with a small distance between the door boxes, the door seal is prone to twisting, resulting in poor sealing, cold leakage, and increased energy consumption of the refrigerator; if the height of the door seal airbag is lowered in order to overcome the twisting, when encountering a refrigerator with a large distance between the door boxes, it is easy to have a flash gap, which in turn causes the refrigerator to leak cold. In this embodiment of the utility model, an inward depression 16 is provided at the right bottom of the second air chamber 7, which can prevent the overall deviation of the door seal structure when the distance between the box body 19 and the door body 17 is small, thereby improving the sealing performance and anti-twisting performance of the door seal structure. Therefore, the door seal mechanism cooperates with the distance compensation provided by the first airbag 4, and can be used in refrigerators with different door box distances, which effectively improves the versatility of the door seal structure, and while ensuring the overall sealing of the door seal structure, it also avoids the occurrence of problems such as twisting.

[0045] In this embodiment of the present invention, the directional descriptions such as up, down, left, and right are only for the convenience of expressing the relative positional relationship.

[0046] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, the door sealing structure may further include a connecting portion 14 and an auxiliary airbag 15 .

[0047] A connecting portion 14 is provided on the side wall of the first air chamber 5 away from the adsorption portion 3 , and an auxiliary air bag 15 is provided on the end of the connecting portion 14 away from the first air chamber 5 . Specifically, the auxiliary air bag 15 is located between the box body 19 and the door body 17 .

[0048] The auxiliary airbag 15 increases the heat-insulating sealing space of the door seal structure. When the refrigerator door 19 is closed, the auxiliary airbag 15 is in close contact with the refrigerator body 19 and the door body 17. On the one hand, the sealing performance of the door seal structure is improved, and on the other hand, the heat-insulating width and heat-insulating performance of the door seal structure are increased, thereby reducing the energy consumption of the refrigerator.

[0049] In this embodiment of the present invention, if Figure 1 As shown, notches are provided at both ends of the connection portion 14. Specifically, a notch is provided below the connection end of the connection portion 14 and the first air chamber 5, and a notch is provided above the connection end of the connection portion 14 and the auxiliary airbag 15. Specifically, the notch can serve as a deformation-giving notch when the first air chamber 5 and the auxiliary airbag 15 are squeezed and deformed, so as to release the squeezing stress and ensure the sealing of the first air chamber 5 and the auxiliary airbag 15.

[0050] In this embodiment of the present invention, if Figure 1 As shown, the top of the first air chamber 5 is tilted upward from left to right, that is, the right top of the second air bag 8 is raised. Specifically, this structure allows the refrigerator door box to be close to the box body 19 when the distance between the refrigerator door boxes is large. At the same time, fewer supporting mechanisms allow the door seal structure to be pressed down more easily when the distance between the refrigerator door boxes is small, and it is not easy to get stuck or twisted.

[0051] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, the adsorption portion 3 may include a magnetic stripe capsule 1 and a first protrusion 2. Specifically, the magnetic stripe capsule 1 is used to install the magnetic stripe, and the first protrusion 2 is arranged on the inner wall of the magnetic stripe capsule 1. Specifically, the first protrusion 2 can increase the roughness of the inner wall of the magnetic stripe capsule 1 on the one hand, and can also limit the magnetic stripe on the other hand, preventing the magnetic stripe from shaking inside the magnetic stripe capsule 1, thereby improving the stability of the magnetic stripe installation.

[0052] In this embodiment of the present invention, if Figure 1As shown, the upper left corner of the magnetic stripe bag 1 is set in an arc shape. Specifically, when the door body 17 is closed, the arc structure of the magnetic stripe bag 1 contacts and rubs against the box body 19. Due to the characteristics of the arc structure, the door seal structure can smoothly slide over the box body 19, avoiding being stuck at the corner of the box body 19, causing the door seal structure to curl, and making the surface of the door seal structure tightly attached to the box body 19 after the refrigerator door is closed, further ensuring the sealing of the door seal structure.

[0053] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, the assembly portion 11 may include a cross-connecting portion 9 and a clamping portion 10. Specifically, the clamping portion 10 may include but is not limited to the bottom of the clamping portion 10 known to those skilled in the art being angled, and the angle tip being provided with a symmetrical undercut structure.

[0054] The transverse connecting portion 9 is arranged at the bottom of the first airbag 4 and the second airbag 8 , and the clamping portion 10 is arranged at the bottom of the transverse connecting portion 9 .

[0055] When the door sealing structure needs to be installed in the assembly groove 18 on the door body 17 , the clamping portion 10 is placed inside the assembly groove 18 to achieve clamping with the assembly groove 18 .

[0056] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, the clamping portion 10 may include an extension portion 13. Specifically, the extension portion 13 is provided at the tip of the clamping portion 10. Specifically, the extension portion 13 contacts the inner wall of the assembly groove 18, which can prevent air from flowing inside the assembly groove 18, thereby reducing heat transfer and further improving the sealing between the box body 19 and the door body 17.

[0057] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, the transverse connecting portion 9 may include a sealing portion 12. Specifically, the sealing portions 12 are provided at both ends of the transverse connecting portion 9, and the sealing portions 12 are inclined toward the door body 17 away from the end of the transverse connecting portion 9. Specifically, the sealing portion 12 can make the door sealing structure fit tightly with the door body 17, ensuring that the left and right sides of the transverse connecting portion 9 will not be lifted and leak cold.

[0058] In this embodiment of the present invention, if Figure 1 As shown, the left and right sides of the first airbag 4 are both C-shaped. Specifically, the C-shaped portion on the right side of the first airbag 4 is arranged to be inclined upward. Specifically, the C-shaped portion can improve the stretching ability and compression buffering ability of the first airbag 4, so as to further improve the sealing performance of the door body 17 and the box body 19.

[0059] In this embodiment of the present invention, if Figure 1As shown, a second protrusion is provided on the inner bottom of the first airbag 4. Specifically, the second protrusion can effectively reduce the overall deformation of the door sealing structure when in use.

[0060] In this embodiment of the present invention, if Figure 3 As shown, when the door sealing structure is applied to the center beam 20 , the top of the side wall of the magnetic stripe bag 1 away from the first air chamber 5 is provided with an extending sealing portion inclined upward, which is used to further improve the sealing performance of the door sealing structure and the center beam 20 .

[0061] On the other hand, the utility model also provides a refrigerator. Specifically, the refrigerator may include a refrigerator body and a door sealing structure. Specifically, the refrigerator body may include a box body 19 and a door body 17, and the door body 17 may include an assembly groove 18; the door sealing structure may include an adsorption portion 3, a first air bag 4, a second air bag 8 and an assembly portion 11. Specifically, the second air bag 8 may include a first air chamber 5, a partition 6 and a second air chamber 7.

[0062] An assembly groove 18 is provided on one side of the door body 17 close to the box body 19. The adsorption portion 3 is used for adsorption connection with the box body 19 of the refrigerator, and the first airbag 4 is arranged below the adsorption portion 3. The second airbag 8 is arranged at the upper right of the first airbag 4 and is located on the right side of the first airbag 4. The second airbag 4 is provided with a partition 6, and the partition 6 divides the second airbag 8 into a first air chamber 5 and a second air chamber 7 which are distributed up and down. The right bottom of the second air chamber 7 is recessed inward 16. Specifically, the recess 16 can also be understood as the right part of the second air chamber 7 forming an arc surface extending to the left from the upper right to the lower right. The assembly portion 11 is arranged below the first airbag 4 and the second airbag 8, and is used to cooperate and snap-fit ​​with the assembly groove 18 on the door body 17 of the refrigerator.

[0063] When the door sealing structure is needed, first fit the assembly portion 11 with the assembly groove 18 on the door body 17 to achieve the installation of the door sealing structure. When the distance between the box body 19 and the door body 17 is large, when the door body 17 is closed, the adsorption portion 3 is adsorbed with the side wall of the box body 19, the first airbag 4 can provide distance compensation, and the first air chamber 5 of the second airbag 8 is in close contact with the box body 19 to achieve the sealing of the door body 17 and the box body 19. When the distance between the box body 19 and the door body 17 is small, when the door body 17 is closed, the adsorption portion 3 is adsorbed with the side wall of the box body 19, the door sealing structure will contact the box body 19 and generate friction, that is, it will squeeze the second airbag 8. Due to the presence of the dividing portion 6, the door sealing structure can remain stable as a whole, avoid large displacement of the upper surface of the sealing structure due to friction, and prevent the overall displacement of the door sealing structure from causing deformation. At the same time, the inward recess 16 at the right bottom of the second air chamber 7 cooperates with the step of the door body 17 to form a clearance space. When the box body 19 squeezes the second airbag 8, the right part of the second air chamber 7 of the second airbag 8 is deformed in the clearance space, further avoiding the overall offset and deformation of the door sealing structure.

[0064] Through the above technical scheme, the refrigerator and its anti-twisting edge door sealing structure provided by the utility model can realize the installation of the door sealing structure by clamping the assembly part 11 in the assembly groove 18 on the door body 17. When the adsorption part 3 is adsorbed and connected with the box body 19, when the distance between the box body 19 and the door body 17 is large, the first airbag 4 provides distance compensation so that the first air chamber 5 of the second airbag 8 can be close to the box body 19 to avoid problems such as flash seams; when the distance between the box body 19 and the door body 17 is small, the box body 19 squeezes the second airbag 8, and the inward recess 16 of the right bottom of the second air chamber 7 cooperates with the door body 17 to form a space for the deformation of the second airbag 8, thereby preventing the overall deviation of the door sealing structure and effectively avoiding the occurrence of problems such as twisting edges. Therefore, the door sealing structure can be suitable for refrigerators with different door box distances, with stronger versatility and good sealing effect.
