Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door device for closing an opening of a cooling storage typified by a household or commercial refrigerator and the like so as to be freely opened and closed.
[0002]
[Prior art]
Conventionally, this kind of refrigerator opens and closes the opening of the heat insulating box that opens on the front surface with a double door as disclosed in, for example, Japanese Patent Laid-Open No. 7-248177 (F25D23 / 02). Such double doors require a partition member that contacts the left and right doors at the center of the opening, but the presence of such a partition member is extremely disturbing in the delivery of food.
[0003]
On the other hand, a partition member extending in the longitudinal direction is attached to the non-pivot side of one door, and the non-pivot side of the other door can abut against the partition member of the one door when both doors are closed. Thus, when both doors are opened, a furniture-type door is also considered in which the partition member is separated from the opening of the heat insulating box together with one door. However, in such a structure, there is a restriction that after closing one door, the other door is closed or only one door cannot be opened.
[0004]
Therefore, in the above publication, a rotatable partition member is attached to the non-pivot side of one door, and when the door is closed, the front surface of the partition member is directed forward at the opening of the heat insulating box, and both doors come into contact with each other. While forming a surface, the structure which rotates a partition member so that the other door may be avoided by the operation | movement which opens one door is taken. According to such a configuration, both doors can be opened and closed independently, and convenience is greatly improved.
[0005]
Hereinafter, the structure of the conventional door 101 will be described with reference to FIGS. 12 and 13. In each figure, reference numeral 102 denotes an outer surface material made of a steel plate. The outer surface material 102 includes a front surface 102A, a side surface 102B formed by bending the edge of the front surface 102A rearward at a right angle with a predetermined curvature, and the side surface. The rear flange 102C is formed by bending the rear end of 102B at a right angle inward.
[0006]
On the other hand, 103 is a door sash, which is formed by extrusion molding of a hard synthetic resin. A projection 103B is formed at the center of the surface of the main body 103A of the door sash 103, and an arm portion 103C is formed on the back surface of the main body 103A corresponding to the projection 103B. Yes. An engagement groove 103D that opens outward is formed between the arm 103C and the main body 103A.
[0007]
The door sash 103 is attached to the outer surface material 102 by inserting and engaging the front end of the rear flange 102C of the outer surface material 102 in the engagement groove 103D. Then, an inner surface material 104 made of hard resin or steel plate is brought into contact with the surface inside the projection 103B of the main body 103A of the door sash 103, and in this state, the inner surface material 104 is loaded into a foaming jig (not shown). And the foam main body 105 is filled between the inner surface material 104 and the door main body 106 is completed.
[0008]
Next, an L-shaped mounting plate 11 as shown in FIG. 13 is fixed to the door sash 103 and the rear flange 102C on the non-pivot side of the door 101 with screws 12. The holder 13 is fixed to the inner plate 104 on the mounting plate 11 with screws 14, and a partition 16 is attached to the holder 13. These mounting plate 11, holder 13 and partition 16 constitute a rotary partition member 17.
[0009]
The partition 16 extends in the longitudinal direction of the door main body 106, has a U-shaped resin main body 21, a steel plate front plate 22 attached so as to close the opening of the main body 21, and these The heat insulating material 23 inserted in the main body 21 and the heater 24 attached to the back surface of the front plate 22 are configured. And the partition 16 is attached to the said holder 13 so that rotation is possible centering | focusing on the axis | shaft extended in a longitudinal direction. Reference numeral 26 denotes a magnet gasket attached to an attachment groove 13A formed integrally with the holder 13.
[0010]
In the state in which the door 101 closes the front opening of the heat insulation box of the cooling storage (not shown), the partition 16 is positioned so that the front plate 22 faces the front and the gasket 26 of the door 101 and the other door. The abutment surface is configured. As a result, the opening is hermetically closed.
[0011]
Next, when the door 101 is opened, the partition 16 is guided by a guide member (not shown) provided on the heat insulating box side, and the front plate 22 is rotated so as to face the other door. As a result, the partition 16 can move forward while avoiding the other door, and both doors can be opened and closed independently.
[0012]
[Problems to be solved by the invention]
However, the angle between the side surface 102B of the outer surface material 102 and the rear flange 102C is not necessarily a right angle (90 degrees), and a processing error (variation) occurs in a direction that becomes a larger angle during production. The rear flange 102 </ b> C is engaged with a sufficient margin in the engagement groove 103 </ b> D of the door sash 103 and receives an outward foaming pressure when the heat insulating material 105 is filled.
[0013]
Due to these various factors, when the door 101 is completed, the inner side material 104 side rises as shown in FIG. 12, and the outer side (rear flange 102C side) of the door sash 103 is lower and the inner side (inner side material 104 side) is higher. Will occur. When such deformation occurs, when the mounting plate 11 of the partition member 17 is fixed to the door sash 103, the holder 13 and the partition body 16 are mounted in an inclined manner as shown in FIG.
[0014]
When the partition 16 is inclined as described above, the front plate 22 of the partition 16 is not flush with the opening of the heat insulation box with the door 101 closed. In addition to the problem of causing leakage, there is also a problem that when the door 101 is opened, the partition 16 comes into contact with the tip of the other door. The former problem is not limited to the rotary partition member 17 but also occurs in a so-called furniture type in which the partition member is fixed to the non-pivot side of the door 101 as described above.
[0015]
The present invention has been made to solve the conventional technical problems, and can be used to attach a partition member to a door sash without hindrance, and to prevent a decrease in sealing performance. The door device is provided with a simple configuration.
[0016]

Yes. An engagement groove 43D that opens outward is formed between the arm portion 43C and the main body 43A.
[0027]
Note that the width A of the engagement groove 43D is configured to be larger than the thickness of the outer surface member 42 shown in FIGS. When the main body 46 is assembled, first, as shown in FIG. 5, the front flange 42C of the outer surface member 42 is inserted into the engagement groove 43D of the door sash 43, and the door sash 43 is attached to the outer surface member 42. In this case, a spacer 51 is interposed between the door sash 43 and the rear flange 42C.
[0028]
As shown in FIG. 6 or FIG. 8, the spacer 51 is made of a thin synthetic resin plate having a substantially rectangular parallelepiped shape or a wedge shape, and is relatively large at a predetermined interval (sufficiently than a screw 12 described later). Through holes 52 are formed of round holes having a large dimension. 7 or FIG. 7 shows the spacer 51 before foaming of the heat insulating material 45 in a state where the inner surface material 44 made of hard resin or steel plate is brought into contact with the inner surface of the projection 43B of the main body 43A of the door sash 43. 8, the door sash 43 is inserted between the back surface of the main body 43 </ b> A and the rear flange 42 </ b> C of the outer surface material 42.

In this state, it is loaded into the foaming jig 61, and the door sash 43 and the inner surface material 44 are pressed down as shown in FIG. Then, the door body 46 is completed by filling the space surrounded by the outer surface material 42, the door sash 43, and the inner surface material 44 with the foam heat insulating material 45 by the on-site foaming method. Since the spacer 51 is inserted between the sash 43 and the rear flange 42C, an error occurs in the bending process of the rear flange 42C of the outer member 42, and the angle X (FIG. 9) is 90 degrees or more. The rear flange 42C is pushed down in FIG. 9 by the spacer 51, the angle formed by the rear flange 42C and the side surface 42B is 90 degrees, and the posture of the door sash 43 is parallel to the front surface 42A of the outer surface material 42. It is corrected (see FIG. 10).
[0030]
An L-shaped attachment plate 11 as shown in FIG. 3 is fixed to the door sash 43 and the rear flange 42C with screws 12 (fixing tools) on the non-pivot side of the door body 46 thus completed. At this time, the screw 12 passes through the through hole 52 of the spacer 51 and is screwed into the door sash 43 and the rear flange 42C. The holder 13 is fixed to the mounting plate 11 on the inner surface material 44 side with screws 14, and the partition 16 is attached to the holder 13.

[0033]
Next, when the door 2 is opened, the partition 16 is guided by the guide member 34 and is rotated so that the front plate 22 faces the other door 33 (shown by a solid line in FIG. 3). Accordingly, the partition 16 can move forward while avoiding the other door 33, and both the doors 2 and 33 can be opened and closed independently.
[0034]
At this time, the posture of the door sash 43 is corrected by the spacer 51 in the direction parallel to the front surface 42A of the outer member 42 as described above, so that the partition member 17 is attached at a normal position without being inclined as in the prior art. Thus, it becomes possible to avoid a decrease in the sealing performance of the doors 2 and 33 due to the inclination of the partition member 17. In particular, since only the spacer 51 is inserted between the door sash 43 and the rear flange 42C of the outer surface material 42, the assembling workability is not deteriorated, and the increase in cost is minimized.
[0035]
Further, the spacer 51 is provided with a through hole 52 having a dimension sufficiently larger than the screw 12 through which the screw 12 for fixing the partition member 17 to the door sash 43 passes. Even if the position of the spacer 51 is slightly shifted (according to the pressure) due to the internal pressure, the partition member 17 can be attached by allowing the screw 12 to pass through without any trouble.
[0036]
In addition, since the spacer 51 has a rectangular parallelepiped shape or a wedge shape, the rectangular parallelepiped shape is effective when the processing error of the outer surface material 42 is large, and the wedge shape has an effect of facilitating the insertion work.
[0037]
