Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a door device for a refrigerator or the like, in which an opening of a heat insulating box is opened and closed by a double-door type door and a back gasket is provided with a gasket for sealing. Regarding

(B) Conventional technology In a conventional refrigerator having this type of double-door type door, gaskets provided on the backs of both doors must form a surface with which a gasket located on the non-pivotal side that keeps the inside of the refrigerator airtight abut. Therefore, for this reason, a blocking member that partitions the opening of the heat insulating box is attached. The gasket is in contact with the front surface of the occluding material to maintain the airtightness in the refrigerator, but it has a drawback that the occluding material reduces the volume in the refrigerator and interferes with the taking in and out of food through the opening.

Therefore, conventionally, for example, as in (I) Japanese Utility Model Laid-Open No. 55-52082, a single-layer or multiple-layer tongue protruding outward is formed on a gasket located on the non-pivotal side of both doors. Although the pieces were brought into contact with each other to seal between the doors, and the above-mentioned closing material was deleted by this, since the deterioration of the airtight performance due to deterioration over time is remarkable, the applicant, for example, (II)
As shown in JP-A-59-180188, a rotatable partition body is attached to the door side instead of the above-mentioned closing member. Also (III)
Japanese Utility Model Application Laid-Open No. 57-156785 discloses a freezer-refrigerator provided with a magnetic catch in order to secure the closing force of the door and the crimping force between the sealing surface of the door partition and the door packing.

(C) Problems to be Solved by the Invention With the configuration shown in (II) above, the partition body constitutes the contact surface of the gasket only when the first door is closed, and the door when the first door is opened. At the same time, since the partition body is separated from the front edge of the opening, it does not hinder the loading and unloading of food, and the airtight performance is sufficiently exhibited. However, since the partition body protrudes toward the user side more than the first door when the first door is opened, the food or the user hits the partition body when the food is taken in and out of the refrigerator. The front surface of the body may turn toward the front side of the door, and in such a rotating state, the first door cannot be closed, and the impact of closing the first door is not only possible. There was a problem that the partition was damaged by. On the other hand, the door partition of the refrigerator disclosed in the above (III) is not rotatably provided with respect to the door, and therefore the first door must be opened and closed after the second door is opened first. No (that is, the order of opening and closing the doors is fixed)
Due to the opening / closing operation of the second door, a large amount of outside air enters the refrigerator, which tends to increase the temperature inside the refrigerator and causes dew condensation on the gasket.

Therefore, the present invention provides a door device such as a refrigerator in which the first door can be opened and closed regardless of the second door state, while the partition body is prevented from accidentally rotating when the first door is opened. The purpose is to

As a result, the guide groove (11) has a substantially arcuate shape, and the inlet portion (11A) on the first door (7A) side is wider. Here, the guide member (30) may be integrally formed with the inner box (3) or may be a separate member.

1 and 5, the doors (7A) and (7B) are formed by foaming and filling a heat insulating material (33) between the outer plate (31) and the inner plate (32). A pair of protruding walls (34A) (34B) on both sides
Is formed, and a gasket (12) having a magnet inserted therein is attached to the peripheral edge of the inner plate (32). When the doors (7A) and (7B) are closed, the gasket (12) is magnetically abutted and held on the front edge of the outer box (2) of the opening (5A) of the heat insulating box (5) to seal the inside (13). To do. Projection wall (34A) (34B)
Plural pairs of ribs (35) are formed on the inner surfaces facing each other, and pockets (36) for placing articles are respectively supported by the ribs (35).

On the outer side of the protruding wall (34B) inside the gasket (12A) located on the non-pivotal side of the back surface of the first door (7A), the cross-section is substantially U-shaped and opens in the gasket (12A) direction and up and down. The storage member (14) is attached. The storage member (14) extends vertically with a dimension slightly shorter than the interval between the upper and lower guide members (30) (30), and has a sixth inner surface on the side wall on the protruding wall (34B) side.
As shown in the figure, a permanent magnet (15) forming a part of the holding member of the present invention is embedded. Also this storage member (14)
In the open end face of the door side of the hinge member (19), the plate (1

A partition body (20) having a substantially rectangular cross section is attached to the plate portion (17) of 9).

The partition body (20) has a length extending substantially above and below the front edge of the opening (5A) and is located above and below the front edge of the opening (5A).
It extends vertically with a dimension slightly shorter than the space between the guide grooves (11) and (11) of (0). As shown in FIG. 1, a flat plate-shaped steel plate (21) is attached to the front surface of the rear portion. Is slightly curved. The partition body (20) is rotatably supported by the hinge member (19) with respect to the storage member (14), and as shown in FIG. 6, the storage member (14).
Stored in and out freely. The upper and lower ends of the partition body (20) project more than the storage member (14) due to their dimensional relationship, and the projecting portion serves as an engaging portion (20A).
Further, a magnetic plate (22) such as a steel plate, which constitutes a part of the holding member, is embedded in the rear surface of the partition body (20), whereby the partition body (20) is housed in the housing member (14). In this state, the partition body (20) is attracted to the permanent magnet (15), and the magnetic force causes the partition body (20) to be easily removed from the storage member (14). Further, semicircular recesses (23) are formed on the end surfaces of the engaging portions (20A).

Next, the rotating operation of the partition body (20) will be described. When the first door (7A) is opened (the second door (7B) may be open or closed at this time), the partition body (20) is inside the storage member (14) as shown in FIG. It is stored in. At this time, for example, the food that the user wants to take in and out is the partition (2
Even if a slight shock is applied to the partition body (20) such as hitting the (0), the partition body (20) tries to maintain this state by the attraction force of the magnetic plate (22) and the permanent magnet (15). There is little risk that the body (20) will rotate. Also, the partition (2
Since the 0) and the storage member (14) are located in the space on the side of the pocket (36) where food is not stored, they are used for storing food in the refrigerator compartment (13). It does not narrow the space, so it does not get in the way when you take food in and out.

When the first door (7A) is closed in this state, the engaging portion (20A) of the partition body (20) is eventually guided from the inlet (11A) of the guide groove (11) on the first door (7A) side. Enter the groove (11),
Next, the corners of the partition body 20) come into contact with the curved surface (10A) of the jetty (10) of the guide member (30), and the partition body (20) starts to rotate by being guided by this curved surface (10A) and the curved surface. The partition body (20) rotates counterclockwise along the direction. At this time the partition (2
0) rotates against the attractive force of the permanent magnet (15),
The magnetic plate (22) is separated from the permanent magnet (15), and at the same time as the closing of the first door (7A), the recess (23) of the engaging portion (20A) causes the projection (9) of the guide member (30). Match the back of. In this state, the steel plate (21) on the front surface of the partition body (20) becomes substantially flush with the front edge of the opening (5A) of the heat insulating box (5), and the door (7A).
The magnetizing surface (that is, the contact surface) of the gasket (12A) of (7B) is constituted, and the opening (5A) is sealed (this state is shown in FIG. 5).

When the first door (7A) is opened from this state, the partition body (20) is guided by the curved surface (9A) which is the rear surface of the protrusion (9) and starts to rotate, and the partition body (20) is partitioned along the curved surface (9A). The body (20) rotates clockwise. By this rotation, the partition body (20) is housed in the housing member (14), and the magnetic plate (22) is again attracted by the magnetic force of the permanent magnet (15) to hold this state.

A projecting wall (49A) is formed on the inner plate (49) only on the pivot side of the door (7A), and the projecting wall (49A) has a rib (53) similar to the projecting wall (34A) of the first embodiment. ) Is provided. In this embodiment, since there is no equivalent to the protruding wall (34B) of the first embodiment, the rib (53) facing the rib (53) is provided on the surface of the storage member (50) facing the protruding wall (49A). Is forming. The storage members (14) and (50) are the same except for the rib (51). A pocket (52) having a slightly enlarged width is supported between the ribs (51) and (53). According to this structure, the inner plate (49) of the first door (7A) has one protruding wall (49A).
Since it is sufficient to form only the above, molding becomes easy.

(G) Effect of the Invention According to the present invention, since the partition body is rotatably attached to the space side of the pocket of the first door, the presence of the partition body narrows the storage space in the refrigerator. Not be done, and
The rotating operation of the partition body is not hindered by the stored food. Further, since the partition body is held in the space side of the first door by the holding member while being rotated to the space side of the pocket side of the first door, the partition body is kept in the space of the pocket side direction in the state of opening the first door. It can be stably held on the side, and in this state the partition does not rotate due to a slight impact such as when the food or the user touches or hits when the food is taken in or out.
Moreover, since the width of the front surface of the partition body is set so as not to project rearward from this pocket, the partition body does not project beyond the thickness of the pocket when the first door is opened.
