Abstract
Description
Technical Field
[0001] This application relates to the field of home appliances, and in particular to refrigerators. Background Technology
[0002] The refrigerator door seal is an important component of a refrigerator, primarily serving to seal the gap between the refrigerator door and the refrigerator body, ensuring that cold air inside the refrigerator does not leak out, while preventing hot air and dust from entering. Refrigerator door seals are generally made of rubber or plastic, achieving their sealing effect through elastic deformation and friction. They are installed around the perimeter of the refrigerator door, forming a tight seal with both the interior and exterior. Refrigerator door seals mainly rely on resilient air bladders to seal the gap between the refrigerator door and the body. However, existing air bladders are usually hollow, resulting in weak insulation. They rely on the inherent resilience of the air bladder material to deform upon contact with the refrigerator body, forming a tight seal. However, the resilience of the air bladder material itself weakens over long-term deformation, leading to a decrease in its sealing performance. Utility Model Content

[0026] The existing airbag 2 has a technical problem of reduced sealing ability under long-term deformation.
[0027] The technical solution provided in this application is to solve the above-mentioned technical problems, and the general idea is as follows:
[0028] Firstly, this application provides a refrigerator door seal, please refer to... Figure 1 The refrigerator door seal includes:
[0029] Mounting bracket, the mounting bracket being used to connect to the refrigerator and install the refrigerator door seal onto the refrigerator;
[0030] Airbag 2, one side of which is connected to the mounting base, and the other side of which is used to contact the refrigerator body and seal the gap between the refrigerator body and the refrigerator door, and the airbag 2 is filled with thermal insulation material 21.
[0031] Airbag 2 is a standard structure for refrigerator door seals, used to contact the refrigerator body and seal the gap between the refrigerator body and the refrigerator door.
[0032] This application fills the airbag 2 with insulating filler 21, which can provide additional insulation to the airbag 2, thereby giving the refrigerator door seal a stronger insulation capability.
[0033] In some embodiments of this application, the thermal insulation filler 21 includes at least one of hollow polyester fiber nonwoven fabric, polypropylene meltblown fabric, polyurethane foam, and EPDM rubber foam.
[0034] It is easy to understand that hollow polyester fiber nonwoven fabric, polypropylene meltblown fabric, polyurethane foam, and EPDM rubber foam, in addition to having good thermal insulation capabilities, also possess good flexibility and resilience. Existing airbags 2 are typically hollow structures, relying on the inherent resilience of the airbag material itself to deform upon contact with the refrigerator body, thus sealing the gap between the refrigerator body and the refrigerator door. However, the resilience of the airbag material itself weakens over long-term deformation, leading to a decrease in its sealing performance. The thermal insulation filler 21 includes at least one of hollow polyester fiber nonwoven fabric, polypropylene meltblown fabric, polyurethane foam, and EPDM rubber foam, which can further enhance the thermal insulation capability of the refrigerator door seal.
[0035] In some embodiments of this application, the refrigerator door seal further includes a sealing sheet 3, one end of which is connected to the airbag 2.
[0036] When the other side of the airbag 2 contacts the refrigerator body, one end of the sealing sheet 3 does not contact the refrigerator body, while the other end of the sealing sheet 3 contacts the refrigerator body and seals the gap between the refrigerator body and the refrigerator door.
[0037] It is easy to understand that when one end of the sealing sheet 3 is connected to the airbag 2, and the other side of the airbag 2 is in contact with the refrigerator body, if one end of the sealing sheet 3 is also in contact with the refrigerator body, the airbag 2 will inevitably deform, thereby reducing the airtightness of the fit between the airbag 2 and the refrigerator body, or even causing the airbag 2 to fail to fit tightly with the refrigerator body. Therefore, it is limited that when the other side of the airbag 2 is in contact with the refrigerator body, one end of the sealing sheet 3 should not be in contact with the refrigerator body.
[0038] It is easy to understand that the other end of the sealing sheet 3 contacts the refrigerator body and seals the gap between the refrigerator body and the refrigerator door, which can further enhance the sealing effect on the basis that the airbag 2 has already sealed the gap between the refrigerator body and the refrigerator door.
[0039] In some embodiments of this application, the distance between the other end of the sealing sheet 3 and the other side of the airbag 2 is greater than the distance between one end of the sealing sheet 3 and the other side of the airbag 2.
[0040] by Figure 1 The refrigerator sealing strip structure is illustrated below. One end of the sealing piece 3 is positioned at the upper left of the airbag 2. Since one end of the sealing piece 3 does not contact the refrigerator body when the other side of the airbag 2 is in contact with it, and the other end of the sealing piece 3 contacts the refrigerator body and seals the gap between the refrigerator body and the refrigerator door, one end of the sealing piece 3 must be positioned below the other side of the airbag 2. Otherwise, when the other side of the airbag 2 contacts the refrigerator body, one end of the sealing piece 3 will also contact the refrigerator body. The other end of the sealing piece 3 needs to be positioned above the other side of the airbag 2; otherwise, when the other side of the airbag 2 contacts the refrigerator body, the other end of the sealing piece 3 may not be able to seal the gap between the refrigerator body and the refrigerator door. In this case, the other end of the sealing piece 3 may be positioned at the upper left or upper right of the sealing piece 3. When the other end of the sealing sheet 3 is positioned at the upper left of the sealing sheet 3, the distance between the other end of the sealing sheet 3 and the other side of the airbag 2 is greater than the distance between one end of the sealing sheet 3 and the other side of the airbag 2. After the other end of the sealing sheet 3 contacts the refrigerator body, the stress generated by the deformation of the sealing sheet 3 has little impact on the airbag 2, and will hardly cause the airbag 2 to deform, thus affecting the sealing degree of the contact between the airbag 2 and the refrigerator body. However, when the other end of the sealing sheet 3 is positioned at the upper right of the sealing sheet 3, the distance between the other end of the sealing sheet 3 and the other side of the airbag 2 is closer than the distance between one end of the sealing sheet 3 and the other side of the airbag 2. After the other end of the sealing sheet 3 contacts the refrigerator body, the sealing sheet 3 is squeezed between the refrigerator body and the airbag 2, which will inevitably cause the airbag 2 to deform, thus affecting the sealing degree of the contact between the airbag 2 and the refrigerator body. Therefore, the distance between the other end of the sealing sheet 3 and the other side of the airbag 2 is limited to being greater than the distance between one end of the sealing sheet 3 and the other side of the airbag 2.
[0041] In some embodiments of this application, the mounting base includes a plug-in portion 11, the cross-sectional shape of the plug-in portion 11 is an isosceles triangle, and the apex of the isosceles triangle points in the direction that the airbag 2 points towards the mounting base.
[0042] It should be noted that in order to install the refrigerator door seal through the plug-in part 11, the corresponding refrigerator door should be provided with a plug-in slot for plugging in the plug-in part 11.
[0043] It is easy to understand that the cross-sectional shape of the plug part 11 is an isosceles triangle, and the direction in which the apex of the isosceles triangle points is the same as the direction in which the airbag 2 points to the mounting base. The beneficial effect is that the apex of the plug part 11 can easily enter the plug groove, thereby making it easier for the plug part 11 to be plugged into the plug groove.
[0044] In some embodiments of this application, the mounting base further includes a first latch 111 and a second latch 112 disposed outside the plug-in portion 11. In the cross-section of the plug-in portion 11, the first latch 111 and the second latch 112 are respectively disposed on the two sides of the isosceles triangle.
[0045] It is easy to understand that the first latch 111 and the second latch 112 are used to engage the plug part 11 into the plug slot.
[0046] In some embodiments of this application, the mounting base further includes a base plate 12, and the airbag 2 and the insertion part 11 are respectively disposed on opposite sides of the base plate 12.
[0047] In some embodiments of this application, the mounting base further includes a connecting portion 13, through which the insertion portion 11 is connected to the base plate 12.
[0048] In some embodiments of this application, one end of the base plate 12 extends outward and is connected to a first fin 121 for protecting the outer door liner of the refrigerator.
[0049] It is easy to understand that after the insertion part 11 is inserted into the insertion slot, the first fin 121 can cover the outer door liner of the corresponding refrigerator door, thereby playing a protective role. The length of the base plate 12 should be set so that the first fin 121 can cover the outer door liner of the refrigerator door.
[0050] In some embodiments of this application, the other end of the base plate 12 is connected to a second fin 122 for protecting the inner door liner of the refrigerator.
[0051] It is easy to understand that after the plug-in part 11 is plugged into the plug-in slot, the first fin 121 can cover the inner door liner of the corresponding refrigerator door to play a protective role.
[0052] Secondly, embodiments of this application provide a refrigerator, the refrigerator including the refrigerator door seal described in any embodiment of the first aspect.
[0053] The refrigerator is based on the refrigerator door seal described in any embodiment of the first aspect. The specific implementation of the refrigerator can be referred to the above embodiments and common knowledge in the field. Since the refrigerator adopts some or all of the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0054] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
