2. Description of the Related Art In recent years, as refrigerators have become larger, refrigerators have come into use that employ so-called double-door door devices in which the opening of the refrigerator compartment is opened and closed by two doors. A conventional configuration of this type of door device is shown in FIG.

In the same figure, on the front side of the opening 2a of the refrigerator compartment 2 formed in the heat insulating box 1 constituting the main cabinet,
First and second doors 3 and 4, each having one end pivoted, are provided to be openable and closable, and magnetic gaskets 3a and 4a are provided on the inner peripheral edges of both doors 3 and 4, respectively. Of both doors 3 and 4, a columnar partition 5 extending in the vertical direction is rotatably provided on the inner surface of the first door 3 on the side opposite to the pivot via a support member 6. Guide grooves 7 having an arcuate shape with one end open are formed at both the upper and lower ends of 5 (
(Only one side is shown in the figure). Further, a torsion coil spring 8 is provided in the support member 6 portion to bias the partition body 5 so as to project laterally when the first door 3 is closed. Guide pins 9 that move in and out of the guide groove 7 are provided at both upper and lower edges of the opening 2a (also only one is shown).

In the case of this structure, when the first and second doors 3 and 4 are both closed as shown by the solid line, the guide pin 9 enters the guide groove 7 and the partition body 5 is held in a state that extends to the side. Also, in this state, each magnetic gasket 3a, 4a of the first and second doors 3, 4 is attached to the peripheral edge of the opening 2a and the front surface 5 of the partition body 5.
a to airtightly seal the inside of the refrigerator compartment 2.

When the first door 3 is opened from this closed state, the guide pin 9 slides relatively along the guide groove 7, and the partition 5 is moved as shown by the two-dot chain line. is rotated so as to face backward while separating from the magnetic gaskets 3a, 4a, and the guide pin 9 is in a state of exiting from the guide groove 7.

In addition, when closing the first door 3 in the open state, the open end of the guide groove 7 fits into the guide pin 9, and the guide pin 9 fits into the guide groove, contrary to the opening operation. As the partition 5 slides relative to the partition 7, the partition 5 is rotated so as to bulge out to the side, and enters the closed state.

[0008]

[Problems to be Solved by the Invention] In such a configuration, when the first door 3 is in a closed state, the front surface 5a of the partition body 5 is configured to be substantially flush with the front line 2b of the opening 2a. This is desirable.

However, in the conventional configuration, due to the dimensional accuracy of each member and variations in mounting position, the front surface 5a of the partition 5 is located in front of the front line 2b of the opening 2a as shown by the dashed line in FIG. The partition body 5 may be installed in an inclined state by protruding toward the rear or retreating backward as shown by the two-dot chain line.

If the partition body 5 is installed in an inclined state as described above, it looks bad when only the second door 4 is opened, and if both the first and second doors 3 and 4 are When closed, the front surface 5a of the partition body 5 and the magnetic gasket 3
a, 4a, or a step may occur between the first door 3 and the second door 4.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to easily and reliably position the partition, thereby preventing a gap from forming between the partition and the magnetic gasket or a step between the two doors. An object of the present invention is to provide a door device for a refrigerator, etc. that can prevent

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a refrigerator door device will be described below with reference to FIGS. 1 to 4.

First, in FIGS. 2 and 3, a heat insulating box body 11 constituting a refrigerator cabinet has an outer box 12 made of steel plate.
A heat insulating material 14 is filled between the inner box 13 and the inner box 13 made of plastic. A refrigerating compartment 15 is formed in the upper part of this insulating box 11, and on both sides of the opening 15a of the refrigerating compartment 15, first and second doors 16 and 17 of double-folding type can be rotated by hinges 18, respectively. is supported by. At the inner peripheral edges of these first and second doors 16, 17,
A magnetic gasket 19 is provided respectively.

Of the first and second doors 16, 17, on the inner surface of the first door 16 on the left side, on the non-pivot side, which is the end side of the second door 17, as shown in FIG. Support members 20, 2
1 are attached to the upper and lower sides by screws 22, respectively, and a partition body 23 is supported by these support members 20, 21 so as to be rotatable about a pin 24, as shown in FIGS. 1 and 2.

The partition body 23 has a columnar shape extending between the upper and lower sides of the opening 15a, and guide members 26 each having an arc-shaped guide groove 25 with one end open, as shown in FIG. 2, are provided at both upper and lower ends. It is provided.

As shown in FIG. 1, the lower support member 21 of the support members 20 and 21 is integrally formed with a protruding positioning portion 27. The portion 27 comes into contact with the side surface 23a of the partition body 23,
The partition 23 is held so that its front surface 23b is substantially flush with the front line 15b of the opening 15a. Further, a torsion coil spring 28 is provided in the lower support member 21 portion, and this torsion coil spring 28 biases the partition body 23 in the clockwise direction when the first door 16 is closed. There is.

Note that the partition 23 is formed with a recess (not shown) for allowing the supporting members 20, 21 and the torsion coil spring 28 to escape when the partition 23 rotates rearward as described later.

Guide pins 29 are provided at both upper and lower edges of the opening 15a, respectively, to fit relatively into the guide groove 25 when the first door 16 is closed.

Next, the operation of the above configuration will be explained. As shown by solid lines in FIG. 2, when both the first and second doors 16 and 17 are closed, the upper and lower guide pins 29 have penetrated deep into the upper and lower guide grooves 25, and the partition body 23
is kept bulging out to the side. In this state, the magnetic gaskets 19 of the first and second doors 16, 17 are adsorbed to the peripheral edge of the opening 15a and the front surface 23b of the partition 23, and the refrigerator compartment 15 is hermetically sealed.

From this closed state, when the first door 16 on the left side is rotated in the direction of arrow A in FIG. 2 to open it, the partition body 23 is rotated in the direction of arrow B (backward) about the pin 22. Accordingly, the guide pin 22 relatively slides along the guide groove 25. As the partition body 23 rotates in the direction of arrow B, each magnetic gasket 19 becomes separated from the front surface 23b of the partition body 23. And the first door 16
When the is rotated as shown by the two-dot chain line in FIG. It will now be held in a rotated position. In this way, the first door 16 is opened.

When closing the first door 16 in the open state, the open end of the guide groove 25 fits into the guide pin 29 as the first door 16 rotates in the direction opposite to the arrow A. Then, the guide pin 29 slides relatively along the guide groove 25,
Accordingly, the partition body 23 is rotated in the direction opposite to the arrow B, and is brought into a state in which it projects sideways, resulting in a closed state shown by the solid line in FIG. 2 .

Note that when opening and closing the second door 17 while the first door 16 is closed, the partition body 23 is held in the sideward position and the second door 17 is opened and closed. The magnetic gasket 19 separates from and attracts the peripheral edge of the opening 15a and the front surface 23b of the partition 23.

According to this embodiment, the partition body 23
A positioning part 27 is provided on one of the support members 20 and 21 supporting the partition body 23, and when the first door 16 is closed, the positioning part 27 comes into contact with the side surface 23a of the partition body 23, and the partition body Since the partition body 23 is held so that its front surface 23b is substantially flush with the front line 15b of the opening 15a, the partition body 23 can be easily and reliably attached to the proper position. Along with this, partition body 2
It is possible to prevent a gap from forming between the front surface 23b of 3 and each magnet gasket 19, or a step from forming between the first and second doors 16 and 17.

In this case, it is conceivable to provide the positioning section on the partition body 23 side, but in this case, the partition body 23 is rotated backward (first door 16 is opened). Since the positioning portion protrudes toward the front side of the partition body 23, there is a problem that the appearance is poor. In this regard, according to this embodiment, since the positioning portion 27 is provided on the support member 21, such a problem does not occur.

Note that in the above embodiment, the opening 15a
The case where the door is opened and closed by so-called double door type first and second doors 16 and 17 is illustrated, but the invention is not limited to this. For example, two drawers are provided above and below the opening, and the first and second doors are provided on the front of both drawers. The present invention can also be applied to a configuration in which a second door is provided and the opening is opened and closed by the first and second doors. In this case, the partition body is
It will be provided on the inner surface of the lower part of the door so as to extend in the horizontal direction.

Furthermore, in the above embodiment, guide members 26 having guide grooves 25 are provided at both the upper and lower ends of the partition body 23, and guide pins 29 are provided correspondingly at both upper and lower edges of the opening 15a. However, the guide member 26 having the guide groove 25 may be provided only on one of the upper and lower ends of the partition body 23, and the guide pin 29 may also be provided on only one of the ends.

Furthermore, the present invention is not limited to refrigerators, but can be similarly applied to door devices for hot storage cabinets and the like.
