Description

Refrigerator door sealing strip capable of preventing condensation

Technical Field

The utility model relates to a refrigerator sealing technique field particularly, relates to a prevent refrigerator door strip of paper used for sealing of condensation.

Background

In order to meet the requirements of the refrigerator door on tightness and convenience in opening, a magnetic strip is arranged in a door seal strip which plays a sealing role between a refrigerator body and a door body. When the refrigerator door is closed, due to the magnetic force action of the magnetic strip, the magnetic strip bag close to the hinge can be in contact with the inner container of the refrigerator body before the outer side air bag of the door seal, so that the position of the magnetic strip bag deviates, the contact area between the magnetic strip bag and the inner container of the refrigerator body is reduced, and the sealing performance is reduced. When the temperature in the refrigerator is low and cold air flows to the refrigerator, condensation can be generated, and the use and the energy saving performance of the refrigerator are seriously influenced.

In addition, the magnetic stripe bag of the existing refrigerator door seal strip adopts a rectangular design, so that the door body is interfered when the refrigerator door is closed, the door seal phenomenon occurs, the refrigerator is not closed tightly, cold leakage is generated, and the energy consumption is increased.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a refrigerator door seal strip of paper used for sealing of preventing condensation guarantees the area of contact of door seal strip and refrigerator box inner bag. The whole appearance of the door seal is attractive and simple, the door seal is easy to weld, and the door seal is durable and economical.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a prevent refrigerator door strip of paper used for sealing of condensation, includes buffering air chamber and fixes sealed cabin in buffering air chamber lower part, buffering air chamber includes: the refrigerator door body comprises a magnetic stripe bag, a main air bag and an auxiliary air bag, wherein the auxiliary air bag is arranged on the inner side of a door seal strip and is attached to an inner container of a refrigerator door body, the main air bag is arranged between the magnetic stripe bag and the auxiliary air bag, the main air bag and the auxiliary air bag share an arc-shaped outer rib, the arc-shaped outer rib protrudes towards the inner container side of the refrigerator body, the main air bag and the auxiliary air bag are separated through a separation rib, and the separation rib is designed in a vertical wavy mode and at least comprises a bent portion.

Furthermore, the outer side cavity wall of the magnetic stripe bag adopts a circular arc design.

Furthermore, an inner supporting rib is arranged at the joint of the inner part of the main air bag and the sealed cabin.

The utility model has the advantages as follows:

1. the outer side cavity wall of the magnetic stripe bag adopts the arc design, so that the magnetic stripe bag is prevented from being worn and broken by the corner part under the action of a long time, and the phenomenon of door sealing caused by the interference of the door sealing corner part on the door body can be prevented.

2. The design that door seals air chamber and refrigerator box contact surface adopted the outer muscle of arc makes the buffering air chamber be superior to magnetic stripe bag and the contact of box inner bag, and the area of contact of increase door seal and inner bag effectively laminates the gap between the refrigerator door body and the box, improves the leakproofness, avoids the condensation phenomenon.

3. The inside wave-shaped separation muscle design that adopts of door seal air chamber, when the refrigerator was closed the door, separated the muscle and extruded, played the effect that supports door and seal the height, prevented that door seal warp too big. When the door is opened, the separating ribs are easy to rebound, the elasticity of the door seal strip is increased, the buffering effect is achieved in the opening and closing process of the door body, the door opening and closing force is moderate, and therefore the service life of the door seal strip is prolonged.

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:

the utility model provides a prevent refrigerator door strip of paper used for sealing of condensation, includes buffering air chamber and fixes sealed cabin 6 in buffering air chamber lower part, buffering air chamber including: a magnetic stripe bag 1, a main air bag 5 and an auxiliary air bag 3.

The refrigerator comprises a magnetic stripe bag 1, wherein a magnetic stripe is arranged inside the magnetic stripe bag 1, and when the refrigerator door is closed, the magnetic stripe in the magnetic stripe bag 1 is attracted to a refrigerator body to ensure sealing. Preferably, the outer side cavity wall of the magnetic stripe bag 1 adopts an arc-shaped design, so that the phenomenon of door sealing caused by interference of the door sealing corner part on the door body can be prevented while the magnetic stripe bag 1 is prevented from being worn and broken by the corner part under the action of long time.

And the arc-shaped outer rib 2 is arranged on the outer wall of the door seal buffer air chamber and is contacted with the inner container of the box body. Preferably, the arc outer rib 2 is protruding to the inner bag side of the refrigerator body, when the refrigerator door is closed, the buffering air chamber is better than the contact between the magnetic stripe bag 1 and the refrigerator inner bag, the contact area between the door seal and the inner bag is increased, the gap between the refrigerator door body and the refrigerator body is effectively attached, the sealing performance is improved, and the condensation phenomenon is avoided.

And the auxiliary air bag 3 is arranged on the inner side of the door seal and is attached to the refrigerator door body liner, so that the heat insulation distance between the door seal and the door body liner is increased, and the integral heat insulation performance of the door seal is increased.
