The receiving seat 22 having such a structure
An arcuate guide groove 23 is formed between a and the jetty 22b. Further, the receiving seat 22a is the receiving seat side end surface 2
It is arranged at a position eccentric to the second door 5 side from the center position of the circumference of 2c. Therefore, the entrance 23a on the first door 4 side of the guide groove 23 is wider than the entrance 23b on the second door 5 side. Also, on the lower surface of the upper guide portion 21B,
A similar receiving seat 22a and jetty 22b are formed.

Next, the closing operation of the refrigerator 1 having the above structure will be described. That is, regardless of the opened / closed state of the second door 5, when the first door 4 is opened, as shown in FIG. The engagement piece 17 is held by the projecting wall 8 by being engaged with the locking piece 15.

In this state, the rotating tip side end surface 11a of the partition body 11 is covered by the projecting portion 20, and the first door 4
The back surface of the has no irregularities and is neat. Further, since the gap S formed between the partition body 11 and the vertical projecting wall 8 is not exposed, the user accidentally thrusts his / her finger into the gap S to engage the engaging claw 17 and the locking piece 15. There is no possibility that the partition body 11 will be erroneously rotated due to the disengagement, and thus the normal opening / closing operation of the first door 4 cannot be performed by such erroneous rotation.

When the first door 4 is closed, the upper and lower ends 11b and 11c of the partition 11 enter the first door-side entrance 23a of the guide groove 23 formed in the guides 21A and 21B.
At this time, as described above, since the receiving seat 22a is disposed at a position eccentric to the receiving seat side end surface 22c, the upper and lower ends 11b and 11c of the partition body 11 are easily inserted into the guide groove 23.

The upper and lower ends 11b and 11c into which the partition 11 has entered the guide groove 23 are guided by the receiving seat side end surface 22c of the jetty 22 and move in the guide groove 23.
The engagement between the locking piece 15 and the locking piece 15 is released, and the partition 11 is shown in FIG.
Rotate counterclockwise in 4. Then, as the rotation progresses,
When the first door 4 is completely closed, the notch 14
Comes into contact with the receiving seat 22a so that they are matched with each other.
Then, the partition body 11 becomes parallel to the first door 4, and the steel plate 13 of the partition body 11 is attracted to the magnetic gaskets 7 provided on the first door 4 and the second door 5, so that both doors 4, 5 The gap T formed between the two is closed by the partition body 11.

On the other hand, when the first door 4 is opened, the upper and lower ends 11b and 11c of the partition body 11 are guided along the guide groove 23, and the partition body 11 is rotated clockwise in the opposite direction to the above, and finally, the partition body 11 is finally rotated. Since the engaging claw 17 engages with the locking piece 15 and the partition body 11 is held by the vertical projecting wall 8, the partition body 11 hardly interferes with the opening operation.

Another embodiment of the present invention will be described below. FIG. 5 shows a second embodiment of the present invention. This modification is characterized in that a shielding member is provided on the partition body 11. That is, the rotating tip of the partition body 11 is provided with the protruding portion 30 formed by protruding toward the vertical protruding wall side. The protruding portion 30 is formed at a position that covers the top of the vertical protruding wall 8 when the engaging claw 17 engages with the locking piece 15 and has a length that covers the entire top of the vertical protruding wall 8.

Next, a third embodiment of the present invention will be described. Figure 6
Shows a third embodiment of the present invention. This embodiment basically has the same configuration as the first embodiment. The difference from the first embodiment is that the locking piece 35 is formed integrally with the vertical protruding wall 8. That is, the partition body side surface portion 36 of the vertical protruding wall 8 is configured as a separate component from the vertical projection wall 8 main body, and the vertical protruding wall 8 attaches the partition body side surface portion 36 to the vertical protruding wall 8 main body by adhesion or the like. It consists of: Further, the partition body side surface portion 36 and the locking piece 35 are constituted by, for example, a resin integral molding product or a metal plate material molding product. In this embodiment, the hinge portion 12 is also integrally formed with the partition body side surface portion 36.

Next, a fourth embodiment of the present invention will be described. Figure 7
Shows a fourth embodiment of the present invention. In this example,
Although the protruding portion 40 that covers the top of the vertical protruding wall 11 is formed at the pivoting end of the partition body 11, the protruding portion 40 has a length that covers only a part of the top of the vertical protruding wall 11. on the other hand,
A recess 41 for accommodating the tip of the protrusion 40 is formed at the top of the vertical protruding wall 8, and when the engagement claw 17 engages with the locking piece 15, the tip of the protrusion 40 has the recess 41. It is designed to be stored in. Therefore, no step is formed between the vertical projecting wall 8 and the projecting portion 40, and since there is no such step, the appearance is cleaner.
Further, the protruding portion 40 also becomes smaller, and the partition 11
In addition to facilitating the manufacture of the partition 11, the strength of the partition 11 is also improved.

[0024]

As described above, according to the present invention, the gap formed between the partition body and the vertical projecting wall is not covered and exposed by the shielding member, and the user accidentally puts his / her finger on the gap. It is no longer possible to let them enter this gap. for that reason,
There is no longer the possibility that the partition will erroneously rotate and the door cannot be opened and closed. Furthermore, since the partition is hidden, the appearance is smoother with less unevenness.
