On the inner surface side of the left and right first and second doors whose side edge portions are rotatably supported in the front-rear direction and which open and close the front opening portion of the same main body, and the front end side edge portions of the first doors. The door is rotatably supported inward and outward, extends vertically along the edge of the first door, and extends outward along the inner surface of the first door when pivoting outward. Column-shaped closing member protruding from the end portion to the tip side and retracting from the tip side edge portion of the door when rotating inward, and upper and lower end portions of the closing member provided at the upper and lower edge portions of the storage body. A guide member for slidingly contacting the closing member to rotate the closing member outward, and when closing the both doors, the inner surfaces of the both doors are The front surface of the peripheral portion of the front opening of the main body is abutted via a seal member to close the periphery of the front opening portion, and the front surface of the closing member is attached to the inner surfaces of the front edge portions of the both doors. There is a double-door type refrigerator configured to be contacted with each other through the gap to close the vertical gap between the front end side edge portions of the both doors facing each other.

The refrigerator is provided with a fixing means for fixing and supporting the closing member to the door when the first door is opened. The fixing means includes a magnet provided on the closing member side and an attraction plate provided on the first door side. When the first door is opened, the closing member rotated inwardly attracts the magnet. It is configured to be adsorbed and fixed to the door by the action.

On the other hand, in the refrigerator disclosed in Japanese Examined Patent Publication No. 5-6133 of the same type as the double door type refrigerator of the above-mentioned type, the closing member is urged inward when the first door is opened and the same door is opened.

In the refrigerator, the dimension between the front surface of the front opening 11a of the cabinet body 11 and the front surface 22a of the guide member 22 is determined by the standing portion 21b of the guide member 21.
The thickness is set to be approximately the same as the thickness before and after.

In the refrigerator, however, the upper and lower hinges 18 are provided with the attraction magnet 19a and the torsion spring 19b. The hinge 18 is shown in FIG.
As shown in FIG. 5 and FIG.
a and a fixed-side hinge portion 18b, and both hinge portions 18a and 18b include connecting arm portions 18a1 and 18b1 and mounting portions 18a2 and 18b2. Movable hinge part 1
8a is attached to the right side surface 16c of the closing member 16, and the fixed side hinge portion 18b is attached to the inner surface of the first door 12, and the connecting arm portions 18a1 and 18b1 of both hinge portions 18a and 18b are overlapped with each other. Support pin 1 in the state
It is rotatably connected via 8c. Both hinges 1
The mounting portions 18a2 and 18b2 of the mounting portions 8a and 18b are provided with facing surfaces facing each other on their surface sides, and when the movable hinge 18a rotates, both facing surfaces of the mounting portions 18a2 and 18b2 advance and retreat.

In the hinge 18, the attracting magnet 19a is fixed to the facing surface of the mounting portion 18b2 of the fixed side hinge portion 18b, and the facing surface of the mounting portion 18a2 of the movable side hinge portion 18a is formed as the attracting surface. ing. Also,
In the hinge 18, the center portion of the torsion spring 19b is fitted to the support pin 18c, and one end of the spring 19b is attached to the attachment portion 18 of the movable side hinge portion 18a.
It is elastically hooked to the back side of a2 and has the same spring 19
The other end of b is elastically hooked to the back surface of the mounting portion 18b2 of the fixed-side hinge portion 18b. As a result, the torsion spring 19b always urges the closing member 16 inward.

In the refrigerator thus constructed,
When the first door 12 is opened, the closing member 16 is rotated inward by the urging force of the torsion spring 19b, is attracted to the magnet 19a, and is fixed to the first door 12 side. In this state, if the first door 12 is closed,
The tip of the standing portion 21b of the guide member 21 on the side of the closing member 16 abuts on the front surface 22a of the guide member 22 on the side of the cabinet body 11 and slides on the front surface 22a.
6 is pushed outward. Therefore, the closing member 16 overcomes the attraction force of the magnet 19a and separates from the magnet 19a, and is rotated outward against the torsion spring 19b. In the state where the first door 12 is completely closed, the closing member 16 is positioned along the inner surface of the first door 12, and the sealing member 16g provided on the closing member 16 is brought into contact with the inner surface of the first door 12. When the second door 13 is in the closed state, the tip portion of the front surface 16a of the closing member 16 is brought into contact with the portion on the tip portion side of the seal member 13d provided on the second door 13. When the second door 13 is in the open state, the closing member 16 is positioned along the inner surface of the first door 12 and the sealing member 16g provided on the closing member 16 contacts the inner surface of the first door 12. When the second door 13 is closed in the opened state, the tip end side portion of the seal member 13d of the second door 13 contacts the front surface 16a of the closing member 16.

As a result, when both doors 12 and 13 are closed, the space between the front edge portions of both doors 12 and 13 is closed by the closing member 1.
6 is airtightly closed, and at the same time, the entire peripheral edge of the front opening 11a of the cabinet main body 11 is airtightly closed via seal members 12d and 13d provided on both doors 12 and 13.
Further, in the guide mechanism 20, the rear surface of the upright portion 21b of the guide member 21 is positioned in contact with the front surface 22a of the guide member 22, and the tip end portion of the seal member 23 provided on the guide member 21 is located in the cabinet main body. By contacting the edge of the front opening 11a of the housing 11, the gap between the tip of the guide member 21 and the edge of the front opening 11a of the cabinet body 11 is airtightly closed. That is, in the refrigerator,
Each of the upper and lower ends of the closing member 16 and the front opening 1 of the cabinet body 11
The gap between the upper and lower edges of 1a is
It is airtightly and surely closed by 22 and the seal member 23.

In the refrigerator, when the first door 12 is closed, the guide member 21 on the closing member 16 side of the guide mechanism 20.
Is the storage body 1 due to the action of the torsion spring 19b.
It is elastically contacted with the guide member 22 on the first side. Therefore, when opening the first door 12, the closing member 16 is gradually rotated inward with the guide member 21 slidingly contacting the guide member 22. When the guide member 21 is separated from the guide member 22, the closing member 16 is further rotated inward to attach the movable side hinge portion 18 a of the hinge 18 to the attachment portion 18.
The facing surface of a2 is attracted to the attraction magnet 19a and fixed to the first door 12 side.

As described above, in the refrigerator, the magnet 19 for attracting and fixing the closing member 16 to the first door 12 side.
Since a and the suction surface are provided on the hinge 18 that rotatably supports the closing member 16 on the first door 12, the closing member 16 receives a bending force when it is held and released from the first door 12. Therefore, the durability of the closing member 16 can be improved without being adversely affected by the deformation of the closing member 16. Further, in the refrigerator, since the arrangement positions of the magnet 19a and the suction surface are determined by the hinge 18 and are accurate, it is not necessary to adjust the positions of the magnet 19a and / or the suction surface. Further, in the refrigerator, the closing member 16 is always urged inward by the action of the torsion spring 19b.

Therefore, even if the closing member 16 is erroneously rotated outward when the first door 12 is opened, the closing member 16 is rotated by the inward urging force and is rotated inwardly. Since it automatically returns to the first state, the state in which the first door 12 cannot be closed does not occur. Further, the closing member 16 is the first door 12
Is securely held by the first door 12 by the biasing force of the torsion spring 19b and the attraction force of the magnet 19a when the first door 12 is opened.
Even if the force to rotate the 6 outward is applied, the closing member 16
Is restricted by the biasing force of the torsion spring 19b and the attracting force of the magnet 19a, so that the closing member 16 will not be accidentally rotated outward when the first door 12 is opened.

In the embodiment described above,
The U-shaped seal member 12d is detachably attached to the inner surface of the first door 12, and the front surface of the closing member 16 is I.
An example is shown in which the character-shaped seal member 16g is detachably provided so that the closing member 16 does not become an obstacle at the time of removal and attachment when exchanging or cleaning these seal members 12d and 16g. Needless to say, is applied to a normal refrigerator in which the first door 12 and the second door 13 are removably attached with a square-shaped seal member. Further, in this embodiment, the seal member 23
An example has been shown in which the guide mechanism 20 provided with is used to reliably seal the gaps between the upper and lower end portions of the closing member 16 and the upper and lower edge portions of the front opening 11a of the storage body 11. ,
