CONSTITUTION:A rotary partition 8 which is rotated by opening/closing action of a first door 6A is provided on a rear surface of the door 6A of double-sided doors 6A, 6B rotatably provided in an opening of a heat insulation box 1, and an angle holding plate 10 for bringing the door 6A into contact with the partition 8 in the closing state of the door 6A.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device for a refrigerator.

[0002]

2. Description of the Related Art In recent years, centerless specifications of refrigerators have been sold for home use or business use. A conventional door device for a refrigerator or the like in the centerless specification is shown in FIG.
Will be described with reference to.

In FIG. 3 showing a conventional door device of a refrigerator, a heat insulating box 1 is constituted by a heat insulating body in which a heat insulating wall 4 made of a foaming heat insulating material is interposed between an outer box 2 and an inner box 3. ,
A first door 6 having a handle 5 at the front opening
A and a second door 6B are provided, and a gasket 7 is provided on the peripheral edges of the back surfaces of the both doors 6A and 6B. On the back surface of the non-pivotal side portion of the first door 6A, the pin 9 is pivoted to the second door 6B side along with the closing operation of the first door 6A to enter the inside of the refrigerator,
When the first door 6A is in the open state, the rotating partitioning body 8 that rotates to the first door 6A side is fixed. A compressor, a condenser, a condenser fan and the like are housed and installed in the upper part of the heat insulating box 1, and an evaporator, an evaporator fan and the like are provided in the upper surface of the inner box 3.

The operation of the door device of the refrigerator constructed as above will be described below.

Since the inside of the heat-insulating box 1 is cooled by a cooling system such as a compressor, a condenser, a condenser fan, etc., the food stored in the inside of the heat-insulating box 1 is opened and closed by the first door 6A or the second door 6B. It is taken in and out by.

When the first door 6A is in the closed state, as shown in FIG. 3, the rotary partition 8 is rotated to the side of the second door 6B to enhance the heat retention effect, and the first door 6A is opened. In the state, the rotary partition 8 does not rotate to the side of the first door 6A so as not to obstruct the loading and unloading of food.

[0007]

In the conventional door device for a refrigerator, the rotary partition 8 and the gasket 7 for the second door 6B are used.
In order to maintain good adhesion with the heat insulation box 1 and to keep the heat inside the heat insulation box 1 good, when the rotary partition 8 is rotated toward the second door 6B, it is rotated toward the first door 6A. It is in a state in which it is rotated by an angle of 90 degrees or more from the state in which it is pressed against the gasket 7 of the second door 6B. However, when the opening and closing of the first door 6A and the second door 6B is repeated, the rotary partition body 8 is deformed and becomes an acute angle from the position rotated to the first door 6A side even when closed, and the gasket of the second door 6B is formed. There is a problem in that the close contact with No. 7 is weakened and a gap is generated between the two, which deteriorates the heat retention effect.

According to the present invention, when the door is in the closed state, the contact strength between the rotary partition provided on one door and the gasket provided on the other door is reinforced to reduce the contact strength, and good adhesion can be obtained. It is an object of the present invention to provide a door device for a refrigerator adapted to be used.

[0009]

In order to achieve the above object, a door device for a refrigerator according to the present invention is provided with an angle holding plate on one of the doors so that the door comes into contact with the rotary partition when the rotary partition rotates. It is the one that enhances the heat retention effect.

[0010]

In the refrigerator door device of the present invention constructed as described above, the opening and closing of the door is continued to rotate to rotate the gasket 7.
By providing an angle holding plate on one of the doors that adheres to the rotating partition even when the contact pressure with it weakens, the temperature effect inside the refrigerator is maintained and the gap between the gasket and the rotating partition is blocked. It is a thing.

[0011]

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

In FIGS. 1 and 2, reference numeral 1 denotes a heat insulating box body, which is constituted by a heat insulating wall 4 in which a foaming heat insulating material is interposed between an outer box 2 and an inner box 3, and has a handle 5 at a front opening. The first and second doors 6A and 6B are pivotally supported in a double-opening manner so that they can be opened and closed.
Is provided. On the back surface of the non-pivotal side portion of the first door 6A,
A handle of the first door 6A, which has a rotary partitioning body 8 which pivots around the pin 9 as a shaft to the second door 6B side and enters the inside of the refrigerator when the first door 6A is closed, as shown in FIG. An angle holding plate 10 that comes into airtight contact with the surface of the rotary partition 8 when the first door 6A is closed is provided on the side surface on the side where the 5 is located. A compressor, a condenser, a condenser fan, etc. are provided on the upper part of the heat insulating box 1, and an evaporator, an evaporator fan, etc. are provided on the upper surface of the inner box 3.

The operation of the door device of the refrigerator constructed as described above will be described below.

The inside of the heat-insulating box 1 is cooled by a cooling system such as a compressor, a condenser, a condenser fan, etc., and the food stored in the inside opens and closes the first door 6A and the second door 6B. It is taken in and out. When the first door 6A is closed, the rotary partition body 8 provided on the back surface of the non-pivotal side portion of the first door 6A rotates simultaneously with the closing operation of the first door 6A, and is shown in FIG. As described above, the rotary partition body 8 and the angle holding plate 10 come into airtight contact with each other, and at the same time, the tip of the rotary partition body 8 pivots around the gasket 7 and the pin 9 of the second door 6B to come into airtight contact therewith.

[0015]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, even if the rotary partition body is deformed due to long-term use and the airtightness with the gasket is deteriorated, the angle holding plate prevents
The contact between the door and the rotary partition and the contact between the gasket and the rotary partition maintain the airtightness, and the stable cooling performance can be maintained without the leakage of cold air in the refrigerator.
