Description

[Detailed description of the invention] The present invention inserts an outward flange formed on the periphery of the front opening of the inner box into a U-shaped groove formed on the periphery of the front opening of the outer box, thereby inserting a heat insulating material into the space between the two boxes. A refrigerator main body that is filled, a partition wall that partitions a front opening in the main body into an upper opening and a lower opening, and a door that independently closes the upper opening and the lower opening, and the partition wall is configured to rotatably support a door that independently closes the upper opening and the lower opening. In a refrigerator equipped with an intermediate hinge attached to the front, the partition wall is prevented from being deformed when a shock is applied to the intermediate hinge due to opening of the door, and a structure is provided in the partition wall to reinforce the intermediate hinge. To provide a structure in which the support plate attached to the inner box will not be damaged by the impact when the door is opened.

Next, embodiments of the present invention will be described in detail based on the drawings.

1 is a refrigerator body, and an outward flange 2A formed at the front opening periphery of an inner box 2 made of synthetic resin is inserted into a U-shaped groove 4 formed at the front opening periphery of an outer box 3, and the outer box 3 is inserted between the two boxes 2 and 3. The space is filled with a foamed polyurethane heat insulating material 5 using an on-site foaming method, and the heat insulating material is sufficiently adhered to the outer box.

Reference numeral 6 denotes a partition wall made of synthetic resin that partitions the front opening in the main body 1 into an upper opening and a lower opening, and constitutes a part that also partitions the inside of the main body 1 into an upper chamber and a lower chamber.

The partition wall 6 has a chamber 7 opened at the front and a front plate 8 that closes the front opening of this chamber.

Reference numeral 9 rotatably supports doors 10 and 11 which are attached to the front plate 8 with an intermediate hinge in a structure to be described later and which independently close the upper opening and the lower opening.

Reference numeral 12 denotes a support plate, which includes an attachment side 12A for attaching to the inner box 2 and an attachment side 12B for attaching to the front plate 8.

Reference numeral 13 denotes a fixing plate whose intermediate portion is in contact with the heat insulating material 5 side of the inner box 2 near the flange 2A, one end is welded to the rear wall 4A of the U-shaped groove, and the other end is buried in the heat insulating material 5.

The mounting side 12A of the mounting plate passes through the inner box 2 and is fixed to the middle part of the fixing plate 13 with a screw 14, and the mounting side 12A to the front plate
2B is fixed with screws 15 together with an intermediate hinge 9 disposed on the front side of the front plate 8 in contact with the back surface of the front plate 8.

The support plate 12 has a locking portion 17 formed on the rear wall of the chamber 7 to reinforce the strength when the protrusion 16 protruding from the end of the door collides with a part of the hinge 9 and stops when the door 10 is opened. A reinforcing side 12C provided with a hook portion 18 that is locked to can be integrally formed.

FIG. 4 shows another embodiment of the present invention.

The inner box shown in FIG. 4 is made of synthetic resin and integrally molded with an upper chamber 2B, a lower chamber 2C, and a partition 2D that partitions these compartments 2B and 2C, as shown in FIG.

In FIG. 4, the partition wall 6 that abuts the front end of the partition portion 2D to partition the front opening of the main body 1 into an upper opening and a lower opening has a structure in which a chamber 7 opened at the front is closed with a front plate 8, and a support plate 12 is attached. Since the structure is the same as that in FIG. 2, these common parts are indicated by the same reference numerals.

In each of the above embodiments, the chamber 7 is filled with a heat insulating material 19 to form a heat insulating partition wall.

As described above, the present invention includes a support plate provided in the partition wall with an attachment side to the inner box and an attachment edge to the front plate of the partition wall, and an intermediate part on the heat insulating material side of the inner box. A fixing plate is provided which abuts and has one end welded to the rear wall of the U-shaped groove and the other end buried in the heat insulating material. It has a structure in which it is screwed to the intermediate portion, and the attachment side to the front plate is screwed together with an intermediate hinge disposed on the front side of the front plate so as to abut the back surface of the front plate.

For this reason, when the door is opened, the impact applied to the support plate through the front plate tends to deform the attachment side of the support plate to the inner box and the inner box, but the fixed plate has one end. Since it is attached to the rear wall of the U-shaped groove and the other end is embedded in the heat insulating material glued to the outer box, the force that tries to deform the inner box is received by this fixing plate and the inner box is No deformation occurs.

It is particularly effective for protecting the inner box in the case of a refrigerator body in which the inner box is covered with a polyethylene bag to protect it from Freon gas contained in the heat insulating material so that the inner box does not adhere to the heat insulating material.

Therefore, it is possible to prevent the impact when the door is opened from deforming the front plate and the inner box.
