Description

Technical Field

[0001] The utility model relates to the technical field of co-extruded door seals with antistatic effect, in particular to a co-extruded door seal with antistatic effect. Background Art

[0002] In order to ensure the sealing and heat preservation function of the refrigerator, the refrigerator sealing strip must have good sealing, elasticity and resistance to compression deformation. The door seals that are widely used at present are made of polymer materials. The material properties and functions directly affect the performance indicators of the refrigerator such as power consumption and sanitary conditions.

[0003] During the production, assembly, transportation and use processes, polymer materials will accumulate surface static electricity of up to several thousand volts due to friction. However, due to the high resistance, insulation and low water absorption of the material itself, static electricity is not easy to eliminate. A large amount of static electricity absorbs dust and oil in the environment, providing a nutrient environment for the growth of bacteria, molds, viruses, etc., causing inconvenience to the cleaning of the door seal, and even affecting human health. Utility Model Content

[0004] The utility model aims to provide a co-extruded door seal with antistatic effect, so as to solve the problem that the existing refrigerator door seal has no antistatic function, easily absorbs dust and oil in the environment, and affects cleaning and use.

[0007] The outer wall of the cabin airbag is provided with cabin inverted wings and cabin arched edges which are assembled in the reserved grooves of the door body;

[0008] An extension airbag is connected to one side of the V-shaped airbag via a V-shaped support rib; a small groove is provided in the extension airbag to facilitate deformation due to compression; wherein the small groove is used to reduce the support of the airbag, so that the airbag is easy to press together, and prevent the refrigerator door from being too elastic when closing, resulting in the door not being closed tightly;

[0009] A magnetic strip is arranged in the magnetic strip airbag for magnetically attracting the door body and the box body;

[0010] A supporting airbag is arranged at the inner bottom of the buffer airbag and directly above the cabin airbag, and an airbag dividing rib is arranged inside the V-shaped airbag.

[0011] Furthermore, an antistatic layer is provided on the outermost layer of the magnetic stripe airbag and the V-shaped airbag.

[0012] Furthermore, the V-shaped airbag includes a "V"-shaped structure that wraps the upper side and the right side of the cushioning airbag, wherein the airbag dividing rib is provided inside the V-shaped airbag and connected to the right side wall of the cushioning airbag; the airbag dividing rib is used to, firstly, enhance the stiffness of the upper surface of the door seal so that the upper side of the door seal is more closely fitted to the box body, and secondly, divide the airbag to reduce the airflow inside the airbag and reduce heat transfer.

[0013] Furthermore, the tip of the V-shaped supporting rib is directed toward the extended airbag, and a small groove is formed at the middle connection of the V-shaped supporting rib; an extended airbag sealing wing is arranged on the outer extension of the extended airbag; wherein the extended airbag extends toward the interior of the refrigerator to increase the sealing area, lengthen the temperature transfer path, extend the temperature gradient, and achieve the effect of energy saving, heat preservation and insulation.

[0014] Furthermore, a plurality of sealing short ribs are arranged on the outer side of the bottom of the V-shaped airbag.

[0015] Furthermore, a U-shaped cavity wall is arranged on the side of the buffer airbag away from the V-shaped airbag; and a cover lining long wing connected to the bottom of the support airbag is arranged below the U-shaped cavity wall.

[0016] Furthermore, a cabin extension wing is provided at the bottom of the cabin inverted wing.

[0017] Compared with the prior art, the beneficial technical effects of the utility model are:

[0018] In the present application, antistatic materials are combined with ordinary polymer materials through a co-extrusion process, which reduces the surface resistance and volume resistance of the material or product, increases its conductivity, eliminates static charge, and can effectively reduce dust absorption and bacterial growth; in addition, the extended airbag extends into the interior of the refrigerator to increase the sealing area, lengthen the temperature transfer path, and extend the temperature gradient, thereby achieving the effect of energy saving, thermal insulation and heat preservation.

[0024] like Figure 1 As shown, in this embodiment, magnetic strips are filled and installed in the magnetic strip airbag 1, which are used for magnetically absorbing the door body and the box body;

[0025] The extension airbag 4 is designed to extend into the refrigerator to increase the sealing area, lengthen the temperature transfer path, extend the temperature gradient, and achieve the effect of energy saving, heat preservation and heat insulation;

[0026] The V-shaped supporting rib 3 located between the V-shaped airbag 2 and the extended airbag 4 is used, on the one hand, to enhance the flatness of the door seal so that the upper side of the door seal fits better with the box body, and on the other hand, to divide the airbag, reduce the airflow inside the airbag, and reduce heat transfer.

[0027] In this embodiment, the tip of the V-shaped supporting rib 3 faces the extended airbag 4, and a small groove 5 is formed at the middle connection of the V-shaped supporting rib 3; an extended airbag sealing wing 6 is designed on the extension of the extended airbag 4; a plurality of small grooves 5 prefabricated on the inner wall of the extended airbag 4 are used to reduce the supporting property of the airbag, so that the airbag is easy to press together, and prevent the refrigerator door from being too elastic when closed and causing the door to be not closed tightly; the extended airbag sealing wing 6 located at the rear end of the extended airbag 4 can be fitted with the box body to form a triangular airbag to form multiple seals.

[0028] The sealing short rib 7 located outside the V-shaped airbag 2 further compensates for the sealing, fit and reliability of the door seal, and can effectively prevent heat exchange between the inside and outside of the refrigerator, thereby reducing the energy consumption of the refrigerator.

[0029] An antistatic layer 15 is designed on the outermost layer of the magnetic strip airbag 1 and the V-shaped airbag 2. The antistatic layer 15 is located on the upper surface of the door seal and is extruded by a co-extrusion process.
