2. Description of the Related Art Conventionally, a refrigerator door structure has, as shown in FIG. 7, one freezing compartment door 2 and two refrigerating compartment doors 3 and 4 over the entire surface of a main body 1. An upper heat insulating wall 5 for partitioning the freezer compartment 7 and the first refrigerating compartment 8 is installed on the upper side inside the main body 1, and the first refrigerating compartment 8 and the second refrigerating compartment 8 are installed on the lower side inside the main body 1. A lower heat insulating wall 6 was installed to separate the refrigerating compartment 9.

In a refrigerator having a conventional structure or another structure, as shown in FIG. 8, one freezer compartment door 52 and one refrigerating compartment door 53 are provided over the entire surface of the main body 51.
A freezer compartment 57 and a refrigerating compartment 6 are provided above the inside of the main body 51.
The intermediate heat insulation wall 60 for dividing 1 and 2 was installed.

In the door of such a conventional refrigerator, the freezing compartment 7, the first refrigerating compartment 8 and the second refrigerating compartment 9 shown in FIG. 7, and the freezing compartment 57 and the refrigerating compartment 61 shown in FIG. When the respective doors 2, 3, 4, 52 and 53 are opened, the structure is hermetically closed by the heat insulating walls 5 and 6 and the intermediate heat insulating wall 60, and the corresponding freezing chambers 7, 57 and the first refrigerating chambers are opened. 8 and the second refrigerating compartment 9 and the refrigerating compartment 61 are open. Further, in the unexplained reference numerals in the drawings, 12, 62 are shelves, 1
3 and 63 are vegetable boxes, and 14 and 64 are covers for the vegetable boxes.

BEST MODE FOR CARRYING OUT THE INVENTION A door structure for a refrigerator according to the present invention will be described below with reference to the drawings. In the refrigerator door structure of the present invention, as shown in FIG. 1, a freezer compartment door 33 and a refrigerating compartment upper and lower doors 22, 33 are provided over the entire surface of the refrigerator body.
In the refrigerating compartment upper door 22, as shown in FIG. 3, hinge brackets 24 are respectively fixed to both of the inner lower ends, and the hinge brackets 24 are adapted to the refrigerating compartment upper door 22. Support 26 formed on the inner side surface of the
A horizontal fixing piece 24a fixed to the lower surface of the same by a plurality of fixing bolts 27, and a vertical piece 24b bent and formed at one end of the horizontal fixing piece 24a at a right angle to reinforce the strength.
And a hinge shaft 24c at the lower end of the vertical piece 24b.
Is formed, and a hooking portion 24d is formed on one side.

Further, a French door 25 having a hinge hole 25a formed on one side of the upper portion (in the embodiment, the door provided so as to rotate horizontally with respect to the upper door 22 of the refrigerating chamber is called a French door). .), And the hinge shaft 24c of the hinge bracket 24 is rotatably coupled to the hinge hole 25a of the French door 25, and the French door 25 is coupled to the refrigerating compartment upper door 22.

Further, a torsion spring 28 is provided for elastically supporting the French door 25 in the direction of warping, and the one side supporting trunk 28a of the torsion spring 28 is provided.
Is fixed to the hooking portion 24d of the hinge bracket 24, and the other side supporting trunk 28b is fixed to the hooking portion 24b formed on one side of the shaft portion of the French door 25.

The French door 25 when the refrigerating compartment upper door 22 is closed is in close contact with the gaskets 22a and 23a placed in the vertical direction and installed on the refrigerating compartment upper door 22 and the refrigerating compartment lower door 23, respectively. As described above, a door standing means is provided.

In the door standing means, a semi-disk shaped cam 29 fixed to one end surface of the French door 25 and a plurality of fixing bolts 3 on the inner wall of the refrigerating chamber 21.
And a cam guide 31 having a cam guide surface 31a fixed by 0, and the cam 29 is attached to the cam guide 31a.
The French door is rotated by contacting and rotating the outer peripheral surface of the French door.

In the drawings, an unexplained reference numeral 32 is a freezer.
33 is a freezer compartment door, 34 is a strength reinforcement stand, 35 is a heat insulating wall for partitioning the freezer compartment and the freezer compartment, and 22b and 23b are magnetic bodies installed on the upper and lower refrigerating compartment doors, respectively. The operation of the door structure of the refrigerator according to the present invention thus constructed will be described.

The refrigerator door structure according to the present invention comprises a main body 2
When the 0 refrigerating compartment 21 is closed by the refrigerating compartment upper door 22 and the refrigerating compartment lower door 23, the French door 25 connected to the refrigerating compartment upper door 22 as shown in FIG.
Are placed vertically. That is, as shown by the phantom lines in FIG. 5, the entire surface of the French door 25 is covered with the gaskets 22a, 23 of the refrigerating compartment upper door 22 and the refrigerating compartment lower door 23.
It is in intimate contact with a and prevents the outflow of cold air from the inside of the refrigerator compartment.

In this case, the French door 25 receives a force to rotate in the horizontal direction due to the elastic restoring force of the torsion spring 28. However, as shown in FIG. Fixed cam 29
Since the rotation is blocked in the state in which is inserted in the cam guide surface 31a of the cam guide 31 fixed to the inner wall of the refrigerating chamber 21 of the main body 20, the state in which it is placed in the vertical direction is maintained.

On the other hand, when the refrigerating compartment upper door 22 that closes the refrigerating compartment 21 of the main body 20 is opened so that the refrigerating compartment upper door 22 moves horizontally, as shown in FIG. The cam 29 formed on the door 25 is disengaged from the cam guide surface 31a of the cam guide 31 and is released from the state in which the rotation is blocked by the cam guide 31.

Therefore, by the hinge bracket 24 fixed to the refrigerating compartment upper door 22, and the elastic restoring force of the torsion spring 28 connecting the French door 25,
From the position indicated by the dotted line in FIG. 5 to the position indicated by the solid line, that is, by rotating in the clockwise direction, as shown in FIG. 6C, the French door 25 is placed and the lower part of the refrigerating compartment is opened by opening the upper door 22 of the refrigerating compartment. The door will not open.

When the opened refrigerating compartment upper door 22 is closed, the French door 25 is maintained in a horizontal state as shown in FIG.
And the lower door 23 of the refrigerating compartment is not contacted with each other, and when the upper door 22 of the refrigerating compartment is almost closed, the cam 29 of the French door 25 is contacted with the cam guide surface 31a of the main body 20.

Next, the cam 29 is guided along the cam guide surface 31a of the cam guide 31, and the French door 25
Is rotated from the position shown in FIG. 6B to the position shown in FIG. 6A by the elastic force of the torsion spring 28 in the reverse direction, that is, rotated counterclockwise, and then placed in the vertical direction again.

On the other hand, when the lower door 23 of the refrigerating compartment is opened, the French door 25 of the upper door 22 of the refrigerating compartment is maintained in the vertical state as it is, and the cold air in the refrigerating compartment 21 is discharged to the outside. Can be reduced.

[0021]

As described above, the refrigerator door structure according to the present invention is provided with the French door which is interlocked with the refrigerating compartment upper door without installing an intermediate heat insulating wall in the refrigerating compartment. The unit price can be reduced and the actual volume of the refrigerating room can be increased to prevent cold air from flowing out of the refrigerator.
