Problems solved by technology

However, in the prior art, when optimizing the structure of the door seal strip, a single factor is often used as the development goal, and the three factors of sealing, heat insulation and strength are not considered at the same time, which leads to new problems in the application process of the door seal strip, resulting in Repeated "rework" design wastes manpower and material resources

Embodiment

[0034] like figure 1 As shown, the present invention proposes a refrigerator door sealant with a strong sealing effect, including four parts: the suction chamber 10, the air chamber group 20, the fixed beam 30 and the fixed chamber 40: the suction chamber 10 is non-suction A solid extruded rib 101 is set on the surface, and a corner flash 102 at a preset angle with the horizontal line is set in the upper left corner of the outside; the air cavity group 20 is divided by a first oblique "S" rib 203 and a second oblique "S" rib 205 It is an outer air chamber 201, a middle air chamber 204, and an inner air chamber 206. A spring-like buffer section 202 is provided outside the outer air chamber. The top of the inner air chamber 206 is designed as an inclined corrugated section structure 207. A gradually expanding umbrella-shaped auxiliary Air cavity 210, upper flash 208 and lower flash 209; outer flash 301 and inner flash 302 with a length of more than 10mm are arranged on both side...

Abstract

The invention discloses a refrigerator door seal adhesive tape with a strong sealing effect. The refrigerator door seal adhesive tape comprises a sucking cavity, a gas cavity group, a fixed beam and afixed cavity, wherein the sucking cavity is equipped with an extruding rib to guarantee tight contact between a magnetic stripe and a sucking surface; an outer gas cavity, a middle gas cavity and aninner gas cavity of the gas cavity group are separated by S-shaped ribs; the outer gas cavity is equipped with a spring shaped buffer section for strengthening deformation compensation effect, in thevertical direction, of a door seal; an inclined corrugated section is designed on the top of the inner gas cavity, so that multi-point contact sealing between the door seal and a box body is realized;a gradual-expansion type umbrella-shaped auxiliary gas cavity can be arranged at the right upper corner of the inner gas cavity to effectively match gradual expansion characteristics of a gap; long flying sides are designed at the two sides of the fixed beam, so that an extra gas cavity can be formed with a door body; and the fixed cavity is equipped with inverted-V-shaped ribs and dual-J-shapedribs for compensating groove gap processing errors. The door seal adhesive tape is good in elastic compensation, is good in structural stability, and can effectively strength the sealing and heat-insulating effects of a refrigerator door seal part.

Description

technical field [0001] The invention relates to the field of refrigerator sealing, in particular to a refrigerator door sealing strip with strong sealing effect. [0002] technical background [0003] The refrigerator is closed all year round, and the cold air in the box and the hot air outside the box mainly exchange heat and mass through the door seal. The infiltration of hot and humid air outside the box not only increases the cooling load of the refrigerator, but also condenses and frosts on the inner wall of the refrigerator, drawers, evaporator, etc., forming a favorable place for bacteria to breed, seriously affecting user experience. Therefore, it is necessary to improve the sealing strength of the door seal. [0004] The refrigerator door seal is composed of a door seal strip and a magnetic strip. The material and structure of the door seal strip are the main factors affecting the sealing performance of the door seal. At present, material improvement and structural...
