BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-door type refrigerator having a good closed state when a door is closed.

[0002]

2. Description of the Related Art In a double door refrigerator, if a refrigerator has a center pillar, it is difficult to put in and out refrigerated goods. Therefore, many double door doors without a center pillar have been manufactured. When used for many years, the free end of the door gradually falls, and there is a problem that a gap is generated at the free end when the door is closed.

[0003] In such a state, a large gap is generated at the butting portion of the upper corner of the free end of the door, and as a countermeasure against this, Japanese Patent Application No. 07-285379 (Japanese Patent Application Laid-Open No. 09-072).
No. 650), "A support is provided inside the front end of each door, a seal member having a bag-like interior is provided at the front end of one support, and the front end of the other support is a metal surface. When the doors are closed, a heater is buried in the column and the sealing member abuts on the tip of the column to seal the gap between the columns, and the heat generated by the heater freezes the sealing member and the column surface. Preventing "technology has been proposed.

[0004]

According to the above-mentioned technology, no gap is formed in the butted portion of the double door with the elasticity of the sealing member having a bag-like interior.
If the gap exceeds the range of the resilience of the sealing member, the gap cannot be eliminated, the cool air in the refrigerator leaks from the gap, and the cool air encounters high humidity outside air and freezes at that part,
This makes it difficult to open the door and eventually damages the seal.

[0005] In view of the above situation, the present invention prevents leakage of cool air from a refrigerator by preventing a gap from being formed at the abutting portion when the door is closed, even when the door of the double door refrigerator is tilted. It is an object of the present invention to provide a refrigerator which prevents the ice from freezing at the butt portion.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a door-sack-shaped guide inside a free end of a door, a guide groove provided in upper and lower end surfaces in the guide, and an edge. The partition body with the sealing material attached is fitted into it, and at the position corresponding to the guide groove on the upper and lower sides of the refrigerator body opening,
When the door is closed, a pin is provided to guide the partition body so as to protrude from the guide, and the sealing material attached to the partition body forms a cavity inside to increase the elasticity. Or a configuration having a roll shape with elasticity.

According to the present invention having the above-described structure, when a gap is generated in the abutting portion due to the inclination of the door, the partition body protrudes and the elasticity of the sealing material causes the partition member to protrude.
The gap is absorbed, and as a result, there is no gap at all. Therefore, there is no leakage of cool air from the refrigerator, and no freezing occurs at the butt portion of the door.
