Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerator sealing, and in particular relates to an energy-saving door seal with high stability. Background Art

[0002] The refrigerator door seal is an important part of the refrigerator, used to seal between the refrigerator door and the refrigerator body. The refrigerator door seal is usually composed of a rubber sleeve and a magnetic strip. The rubber sleeve is the main part of the door seal, and the magnetic strip is the key part of the door seal. Its main function is to use magnetic attraction to make the refrigerator door fit tightly on the door frame when closed, achieving a good sealing effect.

[0003] In some refrigerator products, the distance between the door boxes often varies greatly after the refrigerator door is closed. After the ordinary door seal is installed, it is easy to twist the edge, resulting in poor sealing of the refrigerator, cold leakage, and increased energy consumption. The existing solution is to change the height of the airbag. Disadvantages of the existing technology: Refrigerators with a large range of door box distances are prone to flashing or twisting, resulting in poor sealing of the door seal and cold leakage of the refrigerator. Utility Model Content

[0004] The purpose of the utility model is to overcome the above problems existing in the prior art and to provide a highly stable energy-saving door seal. After the refrigerator door is closed, the door seal is not easy to be twisted at a small door box distance due to the lower airbag height and the larger compensation distance. At a larger door box distance, the surface can also be tightly attached to the box body, thereby ensuring the sealing of the refrigerator. The raised side airbags and the longer auxiliary airbags increase the insulation width of the door seal, thereby enhancing the energy-saving effect of the door seal.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] A highly stable energy-saving door seal comprises a magnetic stripe bag, a side air bag, a crossbeam and a connecting tongue piece, wherein the side air bag is integrally formed and arranged on the right side of the magnetic stripe bag, the connecting tongue piece is integrally formed and arranged on the lower end of the crossbeam, and a connecting rib 1 and a connecting rib 2 are integrally formed and arranged on the upper end of the crossbeam, the connecting rib 1 is located at the left end of the connecting rib 2, the other end of the connecting rib 1 is fixedly connected to the magnetic stripe bag, and the other end of the connecting rib 2 is fixedly connected to the side air bag;

[0007] One end of the cross beam close to the second connecting rib is integrally formed with a first burr edge, and the other end of the first burr edge is fixedly connected to the side airbag;

[0009] An internal cavity is formed between the right end of the second connecting rib, the left end of the first flash edge, the lower end of the side airbag and the upper end of the crossbeam;

[0010] An auxiliary connecting strip is integrally formed at one end of the side airbag away from the magnetic strip bag.

[0011] Furthermore, the magnetic stripe bag is surrounded by a left side strip, an upper side strip, a right side strip and a lower side strip, and the side airbag is integrally formed and arranged on the right side of the right side strip;

[0012] The width of the upper side strip is greater than the width of the lower side strip.

[0013] Furthermore, a reinforcing rib 1 is integrally formed on the right side of the left side strip.

[0014] Furthermore, the inner side and the outer side of the connection between the left side strip and the upper side strip are both in an arc shape;

[0015] The inner side and the outer side of the connection between the left side strip and the lower side strip are both in arc shape.

[0016] Furthermore, the width of the magnetic stripe bag is smaller than the width of the side airbag.

[0017] Furthermore, the height of the magnetic stripe bag is smaller than the height of the side airbag.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] 1. The utility model provides a highly stable energy-saving door seal. After the refrigerator door is closed, the door seal is not easy to be twisted at a small door box distance due to the lower airbag height and larger compensation distance. At a larger door box distance, the surface can also be tightly attached to the box body to ensure the sealing of the refrigerator.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0037] Example 1

[0038] like Figure 1 As shown, this embodiment provides a highly stable energy-saving door seal, which is installed between the refrigerator door body 200 and the refrigerator body 100. Specifically, the energy-saving door seal includes:

[0039] The magnetic stripe capsule 7 is surrounded by a left side strip 71, an upper side strip 72, a right side strip 73 and a lower side strip 74. The side airbag 6 is integrally formed and arranged on the right side of the right side strip 73; the width of the upper side strip 72 is greater than the width of the lower side strip 74; and the inner and outer sides of the connection between the left side strip 71 and the upper side strip 72 are both in an arc shape; the inner and outer sides of the connection between the left side strip 71 and the lower side strip 74 are both in an arc shape;

[0040] Since the magnetic stripe capsule 7 is designed to be a structure that is longer at the bottom and shorter at the top, and the two corners on the left side of the magnetic stripe capsule 7 are both set in an arc shape, the upper end of the magnetic stripe capsule 7 is used to fit tightly with the refrigerator body 100 when the refrigerator door body 200 is closed. Therefore, this design increases the anti-twisting performance of the energy-saving door seal. The energy-saving door seal is installed in the door liner of the refrigerator door body 200. When the refrigerator door is closed, the magnetic stripe capsule 7 at the corner of the energy-saving door seal contacts and rubs with the refrigerator body 100. Because there is a sufficiently large arc-shaped structure and the lower side of the magnetic stripe capsule 7 is longer than the upper side, the energy-saving door seal can slide smoothly through the refrigerator body 100, and it is not easy to be stuck at the corner of the refrigerator body 100, causing the energy-saving door seal to curl. After the refrigerator door body 200 is closed, the surface of the energy-saving door seal is in close contact with the refrigerator body 100, thereby ensuring the sealing of the energy-saving door seal.

[0041] In addition, a reinforcing rib 75 is integrally formed on the right side of the left side strip 71, and is used for squeezing the magnetic strip when the left side strip 71 of the magnetic strip capsule 7 is pressed tightly against the refrigerator door 200, so as to improve the contact tightness between the magnetic strip and the suction surface;

[0042] The side airbag 6 is integrally formed and arranged on the right side of the magnetic strip bag 7;

[0043] Among them, the width of the magnetic stripe bag 7 is smaller than the width of the side airbag 6; the height of the magnetic stripe bag 7 is smaller than the height of the side airbag 6; thus, the side airbag 6 is raised and widened inward, so that the energy-saving door seal can still be close to the refrigerator box 100 when the distance between the refrigerator door body 200 boxes is large, and at the same time, the less supporting structure allows the energy-saving door seal to be pressed down more easily when the distance between the refrigerator door body 200 boxes is small and is under pressure, and it is not easy to be stuck; and the widened side airbag 6 increases the sealing width of the main cross-section of the energy-saving door seal, thereby increasing the sealing performance of the energy-saving door seal;

[0044] The cross beam 10 has a first connecting rib 101 and a second connecting rib 102 integrally formed at the upper end of the cross beam 10. The first connecting rib 101 is located at the left end of the second connecting rib 102. The other end of the first connecting rib 101 is fixedly connected to the magnetic strip bag 7. The other end of the second connecting rib 102 is fixedly connected to the side airbag 6.

[0045] One end of the cross beam 10 close to the second connecting rib 102 is integrally formed with a first fin 103, and the other end of the first fin 103 is fixedly connected to the side airbag 6;

[0046] The end of the cross beam 10 close to the connecting rib 101 is integrally formed with a second fin 104 extending toward the lower left end.

[0047] A connecting tongue piece 20 is integrally formed and arranged at the lower end of the crossbeam 10; specifically, a slot is provided on the refrigerator door body 200, and the connecting tongue piece 20 is buckled in the slot;

[0048] In addition, a second reinforcing rib 107 is integrally formed at the upper end of the crossbeam 10, and the second reinforcing rib 107 is located between the first connecting rib 101 and the second connecting rib 102;

[0049] An external cavity 105 is formed between the right end of the connecting rib 101, the left end of the connecting rib 2 102, the lower end of the magnetic strip bag 7, the lower end of the side air bag 6 and the upper end of the crossbeam 10;

[0050] An internal cavity 106 is formed between the right end of the second connecting rib 102, the left end of the first fin 103, the lower end of the side airbag 6, and the upper end of the crossbeam 10; the internal cavity 106 formed enhances the stability and energy-saving effect of the energy-saving door seal structure. The energy-saving door seal is installed in the door liner of the refrigerator door 200. When the refrigerator door 200 is closed, the energy-saving door seal will contact and generate friction with the refrigerator body 100. The small airbag structure of the internal cavity 106 increases the overall stability of the energy-saving door seal, so that the energy-saving door seal will not cause a large displacement of the upper surface due to friction. After the refrigerator door 200 is closed, the energy-saving door seal is not easy to deviate and deform as a whole, thereby ensuring the sealing of the energy-saving door seal. At the same time, the right side of the small airbag structure of the internal cavity 106 fits tightly with the door liner of the refrigerator door 200, thereby enhancing the energy-saving effect of the door seal.

[0051] An auxiliary connecting strip 60 is integrally formed at one end of the side airbag 6 away from the magnetic strip bag 7, and an auxiliary edge 601 is integrally formed at the other end of the auxiliary connecting strip 60;

[0052] The auxiliary edge 601 increases the heat-insulating sealing space of the energy-saving door seal. The energy-saving door seal is installed in the door liner of the refrigerator door body 200. When the refrigerator door body 200 is closed, the auxiliary airbag is in close contact with the refrigerator body 100 and the door body to form two closed spaces, which increases the heat-insulating width of the energy-saving door seal, enhances the heat-insulating performance of the energy-saving door seal, and reduces the energy consumption of the refrigerator. At the same time, when this auxiliary edge structure is used, after the refrigerator door body 200 is closed, the auxiliary edge 601 is in close contact with the refrigerator door body 200 and the refrigerator body 100 to form a sealed space, which increases the heat-insulating width of the energy-saving door seal;

[0053] The spacing between the vertical side door boxes of the refrigerator fluctuates greatly. The auxiliary side structure can prevent the refrigerator door body 200 from being blocked by the auxiliary airbag, thereby preventing the door from being closed tightly. The auxiliary airbag and the auxiliary side can be butt-welded, so the energy-saving door seal corner can also ensure that the thermal insulation performance of the door seal will not be weakened, thereby ensuring the thermal insulation effect of the door seal.

[0054] In this embodiment, the sealing strip is arranged in the door liner of the refrigerator door body 200. When the refrigerator door body 200 is closed, the small air bag structure of the internal cavity 106 ensures that the energy-saving door seal is not easily displaced and is tightly attached to the door liner. The structure of the magnetic strip bag 7 ensures that the energy-saving door seal is not easily twisted. The auxiliary edge 601 increases the insulation width of the energy-saving door seal. The raised and widened side air bags 6 allow the energy-saving door seal to have a surface that is tightly attached to the refrigerator body 100 and is not easily twisted when the door box spacing is different. This improves the insulation effect of the energy-saving door seal and reduces the energy consumption of the refrigerator.

[0055] Example 2

[0056] like Figure 2 As shown, this embodiment provides a highly stable energy-saving door seal, which is different from the embodiment 1 in that: the other end of the auxiliary connecting strip 60 is integrally formed with an auxiliary air bag 602; the auxiliary air bag 602 is a cavity structure;

[0057] The other end of the auxiliary airbag 602 is integrally formed with a flash edge 603 .

[0058] In this embodiment, since the spacing between the vertical door boxes of the refrigerator fluctuates greatly, the auxiliary connecting strip 60 is used and an auxiliary air bag 602 is extended to prevent the refrigerator door body 200 from being blocked by the auxiliary air bag 602, thereby preventing the door from being loosely closed; after the refrigerator door body 200 is closed, the auxiliary air bag increases the insulation width of the energy-saving door seal; the auxiliary air bag 602 and the auxiliary connecting strip 60 can be welded, so the energy-saving door seal corners can also ensure that the insulation performance of the door seal will not be weakened, thereby ensuring the insulation effect of the energy-saving door seal.

[0059] The utility model provides a highly stable energy-saving door seal. When the refrigerator door 200 is closed, the upper surface of the energy-saving door seal contacts and rubs with the refrigerator body 100 to cause deformation. At this time, the small air bag structure of the internal cavity 106 supports the overall structure of the energy-saving door seal, so that the energy-saving door seal is not easily offset and deformed when in contact and friction with the refrigerator body 100.

[0060] The lower side of the magnetic strip bag 7 is longer than the upper side and the two left corners have a large arc-shaped structure so that the corners of the energy-saving door seal will not be stuck when in contact with the refrigerator box 100, causing the energy-saving door seal to curl and deform, so that the energy-saving door seal can still close the door smoothly without twisting the edge at a smaller door-box distance;

[0061] The auxiliary airbag 602 is deformed under pressure, and the two sides are respectively fitted with the refrigerator door body 200 and the refrigerator box body 100 to form a sealed space, thereby increasing the sealing width of the energy-saving door seal. At the same time, the vertical edge 603 structure makes it difficult for the energy-saving door seal to be stuck at different door-box spacings, thereby ensuring the sealing performance of the energy-saving door seal.

[0062] The side airbag 6 is designed to be raised and widened, so that the energy-saving door seal can have a wider contact surface with the refrigerator box 100 when the door box spacing is larger, thereby ensuring the heat insulation performance of the energy-saving door seal;

[0063] Less supporting structure allows the energy-saving door seal to be pressed down more easily when the refrigerator door body is under pressure with a small spacing between 200 boxes, and it is not easy to get stuck;

[0064] The wider side airbags increase the insulation width of the main cross section of the energy-saving door seal, thereby enhancing the energy-saving effect of the energy-saving door seal.
