Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a refrigerator which opens and closes the opening of a heat insulating box with a double door and is equipped with a gasket containing a sealing magnet on the back of each door. .

(Exposure) Conventional technology Conventionally, this type of refrigerator with double-sided doors forms a contact surface with gaskets located on the non-pivot side of the door in order to keep the inside of the refrigerator airtight using gaskets provided on the back of both shoulders. For this reason, a closing material was installed to partition the opening of the insulating box.The gasket uses the magnetic force of a built-in magnet to come into contact with the front side of the closing material to maintain airtightness inside the refrigerator. However, this material has the disadvantage that it reduces the internal volume of the warehouse and also obstructs the delivery of goods through the opening.

For this reason, in the past, as in, for example, Japanese Utility Model Application Publication No. 55-52082, a gasket located on the non-pivot side of both doors is provided with a single layer or multiple layers of tongue pieces that protrude outward. The seal between the two doors was applied by bringing the two doors into contact with each other, thereby eliminating the above-mentioned blocking material, but since the airtightness deteriorated significantly due to aging, the applicant
As shown in No. 2-63692, a rotatable partition was attached to the door side instead of the above-mentioned closing material.

(c) Problems to be Solved by the Invention In this type of double door opening type, the interior light must be turned on when either the left or right door is opened. Therefore, in the past, it was necessary to provide a plurality of door switches, which are operated by opening and closing each door, at positions that abut each door.

The present invention has been made to eliminate such inconveniences.
