合があった。2. Description of the Related Art Conventionally, a refrigerator having a double door of this type has a gasket provided on the back side of the double door of the double door to keep the inside of the refrigerator airtight. There has been one in which a partition member that partitions the opening of the heat insulating box into left and right is attached as a blocking member for forming the contact surface. However, due to the presence of this partition member, the internal volume of the refrigerator is reduced, and when one door is opened, food cannot be taken in and out of the refrigerator compartment closed by the other door, or it interferes with the taking-out operation. Or there was a malfunction.

As shown in Japanese Patent Application Publication No. 6, the front opening of the refrigerator compartment is closed with two doors, and a middle pillar that forms the sealing surface of the other door is installed on the door inner plate of one door, and A refrigerator having a substantially semi-cylindrical seal member at the upper and lower edges of the seal member, having a semi-cylindrical receiving portion fitted to the semi-cylindrical fin portion of the sealing member, and having a flat receiving portion in close contact with the flat fin portion of the sealing member. In some cases, a receiving member is provided on the inner wall of the main body.

食品の品質を損なう危惧があった。The center pillar of the refrigerator described in the above publication (i) and the middle pillar of the double door of the refrigerator described in the above publication (ii) are provided rotatably with respect to the door. However, since the sealing surface is always fixed in a fixed direction, the opening and closing order of the left and right doors is restricted (that is, one door provided with the center pillar is closed first, and then the other door is closed). There is a restriction that the door must be closed, or the other door must be opened first, and then one of the doors provided with the center pillar must be opened). When it was performed, there was a problem that the center pillar hit the other door and damaged the other door. In addition, since the opening / closing operation of the door that does not need to be opened for taking in / out the food is performed due to the above-described restriction, the amount of outside air flowing into the storage room increases, and the temperature of the storage room rises unnecessarily and the storage room Could not be maintained at a desired temperature or the quality of food might be impaired due to an increase in temperature.

A position adjacent to the concave portion 21 (the concave portion 2 is formed on the upper surface of the second support arm 15 shown in FIG. 4).
On the right side of FIG. 1), a projection 22 is formed to give the other end 19 </ b> A of the coil spring 19 a repulsive force. Especially,
The protrusion 22 has two corners P1 and P2, and a line connecting the corner P1 and the support shaft 16 and a corner P2.
The angles formed by the line connecting the support shaft 16 and the extension line extending from the support shaft 16 to the right side of the support shaft 16 and extending perpendicularly from the support shaft 16 to the side surface of the partition member 17 are approximately 45 ° and 75 °, respectively. ing. These corners P1 and P2 are connected to the second support arm 1
The other end 19 of the coil spring 19 is
This is for determining the starting point when the counterclockwise repulsion force given to A in FIG. 4 is converted into the rotational moment of the second support arm 15. The coil spring 19, the recess 21, and the protrusion 22 constitute a rotation assisting device that assists rotation of a partition member 17 described later.

The other end 19A of 9 is engaged in the concave portion 21, and the partition 17 is stopped at the position shown by the two-dot chain line in FIG. When the door 7A is open, the heat insulating box 5
(That is, in this case, the partition 1
Since item 7) does not exist in the compartment 13, it is possible to easily put a hand not only on the side where the door is open but also on the side where the door is closed, so that articles can be easily taken in and out. When the door 7A is closed from the state where the door 7A is open, the partition 17
The rear corners of the curved portion 17A formed on the upper and lower ends contact the guide surface 11A of the second guide portion 11. When the door 7A is further closed, the curved portion 17A is guided by the guide surface 11A.
A turns counterclockwise along A, and further turns counterclockwise from the position shown in FIG. 6 against the repulsive force of the other end 19A of the coil spring 19. When the angle between the extension line of the first support arm 14 extending inside the storage and the second support arm 15 reaches a position of about 45 °, the other end 1 of the coil spring 19
Since 9A is located at the corner P1, when the door 7A is further closed beyond the corner P1, the door 7A is over the portion that gives the coil spring 19 a repulsive force. The partitioning body 17 is further rotated counterclockwise by the repulsive force.

By forming only the front surface of the partition body with a magnetic material, the adhesion of the gaskets 12A, 12A can be further improved. The width of the front surface of the partition 17 is gasket 12A,
It is preferable that the distance is set in advance so as to be sufficiently larger than the interval of 12A.

Moves clockwise while hitting the curved surface 9A of the first guide portion 9, so that the partition 17 rotates clockwise to a position as shown in FIG. 5 against the repulsive force of the other end 19A of the coil spring 19, The gasket 12A separates from the contact surface (that is, the front surface) of the partition 17. When the door 7A is further opened and the angle between the extension of the first support arm 14 and the second support arm 15 reaches a position of about 15 °, the other end 1 of the coil spring 19
Since 9A is located at the corner P2, if the door 7A is further opened beyond the corner P2, the partitioning body 17 is rotated clockwise by the repulsive force applied to the other end 19A of the coil spring 19, and the door 17A is rotated. 7A is stopped after reaching the position shown by the two-dot chain line in FIG. Therefore, when the door 7A is opened until the angle formed by the extension line of the first support arm 14 and the second support arm 15 becomes about 15 ° or less, the door 7A is easily turned in the opening direction by the repulsive force of the coil spring 19. Can move.

Further, the interval between the second guide portion 11 and the first guide portion 9 is configured such that the upper and lower end portions of the partition member 17 can pass smoothly.

切体を設けた一方の扉の開閉操作を行うことができる。According to the present invention, the direction changing portion provided above or below the opening edge causes the partition body to be hit by the projection of the partition body when the one door provided with the partition body is opened. It acts so as to perform two operations of shifting to one of the doors to an upright position, and shifting a part of the partition body to a side of the one door when the door is closed. Therefore, the partition body and the other door do not interfere with the opening / closing operation of one of the doors, and the pivoting operation of the partition body toward the standing position or the protruding position is ensured. In particular, by closing one of the doors, a part of the partition body projects laterally of this door, and the front surface of the partition body serves as the contact surface of the seal member located on the non-pivotal side of the double door, It is not necessary to previously attach a partition member for abutting the seal member located on the non-pivotal side of the door to the heat insulating box body, and the partition member does not narrow the storage space of the refrigerator, and the heat insulating box All of the openings in the body can be used as a food intake / outlet opening, which improves the usability of the refrigerator. Moreover,
In addition to eliminating the conventional problems of insufficient adhesion and loss of airtightness due to friction between seal members, one door with a partitioning body is independent of the opening / closing operation of the other door. You can open and close.
