Description

Cold-leakage-proof refrigerator door seal

Technical Field

The utility model relates to a refrigerator sealing technique field particularly, relates to a cold refrigerator door strip of paper used for sealing of leak protection.

Background

The refrigerator door sealing strip is a component which plays a role in sealing between the refrigerator body and the door body when the refrigerator door is closed, is tightly matched with the refrigerator body and the door body, can prevent cold air in the refrigerator from leaking and prevent external hot air from invading, and is the most direct factor influencing the whole sealing performance of the refrigerator.

However, in the actual use process, the refrigerator door seal and the refrigerator body are prone to faults of loose closing. For example, a 'flash seam' appears after assembly, cold air flows out along the seam, the refrigeration effect is poor, the power consumption is increased, and even the compressor is overheated due to overlong operation time of the refrigerator, and finally the compressor is burnt out. Or, when the distance between the refrigerators is large, the door seal with poor elasticity deforms due to frequent door opening and closing, and cannot make up gaps between the doors, so that cold leakage is caused, and the overall performance of the refrigerator is affected.

Therefore, how to carry out the optimal design on the basis of the existing door seal meets the higher and higher sealing requirements of the refrigerator, and becomes a problem which needs to be paid attention to and solved by the industry urgently.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application.

The first embodiment is as follows:

as shown in figure 1, the refrigerator door seal for preventing cold leakage comprises a magnetic stripe bag 101, an inner side air bag 102, a main air bag 104, a supporting small air bag 105 and a sealing small room 106. The magnetic strip is arranged in the magnetic strip bag 101, and when the refrigerator door is closed, the magnetic strip in the magnetic strip bag 101 is attracted to the refrigerator body to ensure sealing. The inner side wall of the magnetic stripe bag 101 is provided with a blocking rib 110 for preventing the magnetic stripe from sliding, so that the magnetic stripe is prevented from sliding off in assembly and use.

Inboard gasbag 102, the setting is in the inboard of magnetic stripe bag 101 and with magnetic stripe bag 101 is connected, and preferably, inboard gasbag 102 upwarps 10-20 along magnetic stripe bag 101 to the box direction, makes the door seal higher with the box laminating degree, and the vertical distance between the sealed door body and the box prevents that air conditioning from flowing out between door seal and the box inner bag that can be better, reduces to leak coldly. The wavy inner sealing fin 103 extending towards the door body direction is arranged on the lower cavity wall of the inner air bag 102, the wavy design is adopted, the thickness is reduced, the inner sealing fin 103 can be bent freely during assembly, when the door body is closed, the inner sealing fin 103 abuts against a door liner, the gap between the door seal and the door body is blocked, cold leakage is reduced, the strength is increased, meanwhile, the interference of the inner sealing fin on the installation of the door seal can be prevented, and the door seal is prevented from being damaged.

The main air bag 104 is arranged below the magnetic stripe bag 101 and is connected with the magnetic stripe bag 101, and the main air bag 104 is arranged at the lower part of the magnetic stripe bag 101, so that the good heat insulation property of the air bag is fully utilized, and the cold leakage prevention effect is better; the outside chamber wall resilience rib 109 of main gasbag 104 adopts vertical muscle from top to bottom and the rib combination design that kick-backs of "U" type to one side, and when the door seal received the extrusion, the "U" type muscle to one side was compressed, and vertical muscle provides the support from top to bottom, guarantees the door seal holistic pressfitting height, prevents to warp the hourglass cold that too big arouses. When the pressure is weakened or disappears, the inclined U-shaped rib restores the original shape, and the resilience of the door seal is ensured. The supporting small air bag 105 is arranged on the inner lower cavity wall of the main air bag 104, so that the supporting strength of the door seal is further improved, and the phenomena of deformation and cold leakage caused by the deterioration of the supporting force of the door seal are prevented. The corner of the small supporting air bag 105 is designed to be an oblique angle, so that the pressed corner of the door seal is prevented from being broken by friction with the inner wall of the main door seal air bag 104. The inner side air bag 103 and the main air bag 104 adopt the design of separate independent air bags, so that the door seal is integrally more attached to the door liner, the drawing height of the whole door seal is improved, and the adaptability of the door seal and the door liner is improved.

The lower part of the main air bag 104 is provided with a sealed cabin 106, the sealed cabin 106 is connected with the main air bag 104, the sealed cabin 106 is connected to a refrigerator door body through a clamping groove, a cabin sealing fin 107 is further arranged at the end part, attached to the clamping groove of the door body, of the sealed cabin 106, a gap between the sealed cabin 106 and the clamping groove is divided into two parts, air convection in the sealed cabin is reduced, and air tightness is improved.

The cover lining sealing fin 108 is positioned at the joint of the main airbag 104 and the sealing cabin 106 and extends towards the door body, so that the installation parts of the door seal and the door body are effectively shielded, and the cold leakage phenomenon at the groove opening is reduced.

The utility model discloses in the door seals for materials such as soft polyvinyl chloride (PVC) elastomer, polyolefin thermoplastic elastomer (TPE), silicon rubber, and the material is safe, meets the requirements.
