DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing roller for supporting a drawer door which can be freely inserted into and removed from a front opening of a refrigerator, and a fixing member for fixing the fixing roller.

[0002]

2. Description of the Related Art Prior to the present invention, Japanese Utility Model Publication No. 62-1455.
In the rail pull-out device described in Japanese Patent Publication No. 5 (1993), a screw plate for screwing a fixing roller supporting a drawer door is mounted in advance on a heat insulating material side of a resin inner box, and the screw plate is mounted. The inner box is inserted into a metal outer box, and a heat insulating material such as polyurethane foam is filled between the inner and outer boxes to form a heat insulating box.

[0003]

The rail pull-out device described in the above-mentioned publication mounts a screw plate on an outer surface of a resin inner box side wall and inserts the inner box into the outer box. Since the inner box is made of resin and has a considerably thin wall thickness of about 1 mm, the inner box itself is easily bent, so that the inner box is inserted into the outer box using this bending.
However, when inserting the inner box into the outer box while flexing the inner box, it is difficult to set the inner box itself in a symmetrical state, and the left and right rails and fixing rollers to be fixed to the inner box side wall are in a left-right relationship. The drawer door cannot be set in a symmetrical state. There was a problem that could not be set. In order to solve this problem, it is conceivable to provide a positioning member in both boxes in advance to align the two boxes when inserting the inner box into the outer box. However, the number of parts and the number of work steps are increased. Etc. There was another problem.

Accordingly, an object of the present invention is to provide a refrigerator that solves the above-mentioned problem by fixing a fixing member that also serves as a positioning member when inserting the inner box into the outer box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a refrigerator according to the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a front open-type refrigerator, which comprises an outer box 2 having a front opening made of a steel plate which has been coated in advance, and an inner box 3 made of resin such as ABS which is arranged in the outer box with a space therebetween. A heat insulating box 5 having an open front face made of a heat insulating material 4 such as foamed polyurethane injected and foamed between the inner and outer boxes 2 and 3, and a plurality (in this example, upper side in this example) of which the opening of the heat insulating box 5 is openably and closably closed. (Three middle and lower) thermal insulation doors 6, 7 and 8.
In the present embodiment, the upper two doors 6 and 7 are pivotal doors provided corresponding to the freezing room and the refrigerator compartment, and one door 8 located at the lowermost portion corresponds to the vegetable room. The door 8 is hereinafter referred to as a drawer door.

The drawer device 10 for holding the drawer door 8 in and out will be described below.

Reference numeral 11 denotes a pair of left and right receiving members horizontally mounted rearward on the rear portion of the drawer door 8, which detachably receive a container 12 having an upper opening for storing mainly breathable foods such as vegetables and fruits. It is. This receiving member 1
A roller 13 guided by a rail 15 to be described later is attached to a rear portion of each of the rollers 1. Reference numeral 14 denotes a pair of left and right grooves opposed to the left and right side walls of the inner box 3 and integrally formed in the front-rear direction.
Are mounted on the rail 15 to guide the rails in the front-rear direction. A fixed roller 3 for supporting the receiving member 11 of the drawer door 8 is provided in front of and above the groove 14 of the inner box 3.
In order to fix 0, a hole 16 having a larger diameter than the hole is formed corresponding to a hole 25 described later.

Reference numeral 17 denotes a flange bent at the opening edge of the outer box 2, and flanges 17 formed at the left and right opening edges.
A notch 18 and a square hole 19 for attaching a fixing member 21 to be described later are formed at appropriate places. It is preferable that the flange 17 be bent three times so as to form a groove for disposing the dew-prevention pipe. A notch 18 and a square hole 19 are formed at the rearmost position. I have.

Reference numeral 21 denotes a metal fixing member fixed to the flange 17 so as to contact the outer surfaces of the left and right side walls of the inner box 3.
The fixing member 21 includes a contact portion 22 that contacts the inner box 3, a mounting portion 23 that is mounted on the flange 17, and a holding portion 24 that functions as a spacer that holds the space between the inner and outer boxes, and has a substantially cross-sectional view. It is formed in a U-shape. A hole 25 for fixing the fixing roller 30 is formed in the contact part 22, and a mounting part 23 extends rearward from the front side 27 having a claw 26 inserted into the square hole 19 and the front side 27. A rear side 28 is formed so that the front side is parallel. In addition, the mounting portion 23 makes the claw 26 of the front side 27 come into contact with the front surface of the flange 17 so as to be inserted into the square hole 19 from the front of the square hole 19, while the rear side 28 makes contact with the rear surface of the flange 17. The front side 27 and the rear side 28 are attached to the flange 17 so as to sandwich the flange. However, it is preferable that the front side 27 and the rear side 28 are fixed with an adhesive or welding in order to improve the strength at the time of attachment. . Reference numeral 29 denotes a reinforcing plate attached to the outer surface of the contact portion for reinforcing the contact portion 22.

The procedure for mounting the drawer device will be briefly described based on the above configuration. First, the fixing member 21 is fixed to the outer box 2 by attaching the mounting portion 23 to the flange 17. Next, the inner box 3 is inserted into the outer box 2 so that the mounting side 31 formed at the opening edge of the inner box 3 faces the groove and is positioned in front of the mounting portion of the fixing member 21. Is brought into contact with the contact portion 22. At this time, the hole 1 formed in the inner box 3
The inner and outer boxes can be positioned by aligning 6 with holes 25 formed in the fixing member 21. Then, the rail 15 is fixed to the groove 14 of the inner box 3 with a screw or the like, and the fixing roller 30 is fixed to the hole 25 through the hole 16. Thereafter, the two boxes are assembled to a foaming jig (not shown), and a heat insulating material is filled between the two boxes, whereby the heat insulating box 5 is completed.

Although the example in which the rail 15 and the fixing roller 30 are fixed prior to the foaming operation has been described, both may be fixed after the foaming operation.

As described above, since the fixing member 21 is attached to the outer box 2, the positions of the left and right fixing members do not shift in the height direction due to the insertion of the inner box unlike the conventional case. Since the hole 25 formed and the hole 16 formed in the inner box 3 function as a positioning member, it is not necessary to provide a special positioning member. Further, since the outer surface of the inner box side wall is brought into contact with the abutting portion 22 of the fixing member 21, the fixing member can be used as a spacer for maintaining a space between the inner and outer boxes.

In this embodiment, the outer box is bent at the opening edge.
