BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a refrigerator according to the present invention; FIG. This freezer compartment 2 has a front opening closed by so-called double doors of the first door 3 and the second door 4. Reference numerals 5 and 6 denote gaskets containing permanent magnets attached to the peripheral edges on the rear side of the doors 3 and 4. 7 is a rotary partition attached to the first door 3. The rotary partition 7 is rotatably pivoted by an upper hinge 9 and a lower hinge 10 attached to a door inner plate 8.

The rotary partition 7 has a case 11 made by extrusion molding or the like, and upper and lower pieces 12 and 13 of an injection-molded product mounted on the upper and lower sides thereof. It has an iron plate 14 and the like constituting a magnetized surface up to a gasket containing a permanent magnet, and further has a case 11, pieces 12, 13,
The space surrounded by is filled with a heat insulating material 15.

Reference numeral 16 denotes a back surface of the iron plate 14 and a heat insulating material 15.
A heating element such as an electric heater disposed therebetween. This heating element 16
Is attached for the purpose of eliminating moisture that tends to condense on the surface of the iron plate 14.

Further, the right and left flange portions 14 of the iron plate 14 are provided.
It is good to make a and 14b as short as possible.
On the contrary, the upper and lower flange portions 14c, 14
d is formed to be relatively long and large so as to cover most of the surfaces 12a and 13a of the pieces 12 and 13. Therefore, the heat heated by the heating element 16 is applied to the surface 1 of the pieces 12 and 13.
The portions 2a and 13a can be sufficiently heated.

Next, the mounting relationship between the iron plate 14 and the case 11 will be described.

For example, when the width of the case 11 is 50 mm,
The width of the iron plate 14 is formed to be 30 mm. That is, iron plate 1
4 is attached to a place where 10 mm is located on both sides of the case 11.

The magnetized portions 5a, 6a of the gasket in which the permanent magnets are built are located on the iron plate 14, and the magnetized portions 5a, 6a
The bag portions 5b and 6b formed on the side of a are located at a position of 10 mm of the case 11. This prevents the heat in the freezer 2 from being transmitted to the iron plate 14 through the gaskets 5 and 6 as shown in FIG.

Reference numeral 17 denotes a guide mounted on the upper surface of the freezer compartment 2, and reference numeral 18 denotes a guide mounted on the lower surface. The guides 17 and 18 are formed in a substantially half-moon shape as shown in FIG.

Reference numerals 19 and 20 denote holding pieces provided at the ends of the guide portions 17a and 18a of the guides 17 and 18, respectively. The pieces 12 and 13 are semi-lunar guide portions 17a formed by the guides 17 and 18. , 18a.

The holding pieces 19 and 20 help the pieces 12 and 13 to escape from the guide portions 17a and 18a.

That is, when the holding pieces 19 and 20 are not provided, the rotary partition 7 is maintained in an open state to form a gasket receiving surface on the second door side by a spring described later.

Therefore, when the first door 3 is to be opened, the rotary partition 7 is kept open and the guide portion 17 is kept open.
a, it comes out from 18a.

The holding pieces 19 and 20 prevent this, and even if the first door 3 starts to open, the rotary partition 7 is pressed by the holding pieces 19 and 20 so that the upper and lower hinges 9 and 20 can be used.
Rotating around the center 10, the spring 21
Thus, the rotary partition 7 is folded as shown in FIG.

The point at which the force folded from the holding pieces 19 and 20 is transferred to the spring 21 is that the turning operation of the rotary partition does not open the door 4 on the other side.

Reference numeral 21 denotes a spring for holding the rotary partition 7 in an open state (a state where a gasket receiving surface of another door is formed) and a closed state (a state close to the door inner plate 8).

As shown in the drawing, the spring 21 has one end attached to the door inner plate 8 and the other end attached to the rotary partition 7 side, and has a coil therebetween.

Then, as shown in FIG.
When the spring mounting point Q on the rotary partition body side is on the door inner plate 8 side with respect to a straight line Y connecting a to the mounting point P on the door inner plate 8 side, the spring 21 moves the rotary partition body on the door inner plate 8 side. When it is on the side opposite to the door inner plate 8, it functions to hold the rotary partition on the open side.

Accordingly, the holding pieces 19 and 20 described above function to rotate the rotary partition 7 in the guide portions 17a and 18a until the spring attachment point Q of the rotary partition 7 passes through the straight line Y. It is.

In the case of a freezing compartment provided with a rotating partition for a freezing compartment having such a structure, there is no fixed partition in the freezing compartment, so that the usability is good and the heat seal of the rotating partition is good. The opening and closing operation of the first door provided with can be performed smoothly.

Next, this will be described.

First, when the first door 3 is shifted from the "open" state to the "closed" state, the upper and lower pieces 12, 13 of the rotary partition 7 held on the door inner plate 8 side are guided as shown in FIG. The upper and lower pieces 12, 13 are guided to the guide portions 17a, 18a, respectively,
The rotary partition 7 starts moving toward the open state. At this time, a force is applied to the rotary partition 7 to press the rotary partition 7 against the door inner plate 8 side. However, when the mounting point Q of the spring 21 passes through the straight line Y once, The spring 21 attempts to rotate the rotary partition 7 toward the end of the guides 17a and 18a. This force also serves as a door closer, which was conventionally mounted to automatically close the door just before the door closed. The force for closing the door 3 and the force for intentionally closing the door 3 combine to form the upper and lower pieces 12 and 13 of the rotary partition 7.
Is reached to the ends of the guide portions 17a and 18a, and the door 3 is closed.

On the other hand, when the first door 3 is to be shifted from the "closed" state to the "open" state, the rotary partition 7 is moved as shown in FIG. 5 until the door 3 is opened to some extent as shown in FIG. The holding pieces 19 and 20 are prevented from coming forward, and the hinges 9 and 1 are prevented.
Rotate around 0.

When the door 3 is opened until the spring attachment point Q passes through the straight line Y, the rotary partition 7 is rotated toward the door inner plate 8 by the force of the spring 21.

In this state, the door 3 can be opened without any influence on the door 4.

While the opening / closing operation is performed, the rotary partition body 7 prevents the transfer of heat by the following means. That is, while the heat of the iron plate heated by the dew-prevention heating body provided to prevent the dew from being attached to the surface of the rotary partition body 7 due to the temperature difference tries to enter the freezing compartment 2, , The width of the iron plate 14 is smaller than the width of the rotating partition pair 7,
Moreover, it is prevented by making the iron plate side flanges 14a and 14b small.

On the other hand, the upper and lower pieces 12, 13 of the rotary partition 7
A space 22 (gap for rotation) formed between the upper and lower pieces 12, 13 is heated by the heater 16 through the upper and lower flanges 14c14d of the iron plate 14, so that cold air enters and exits. It is to prevent.

Further, the flow of heat between the freezer compartment and the outside of the refrigerator is improved by the contact between the bag formed on the side of the gasket with a built-in magnet and the surface of the rotary partition (where there is no iron plate). It will be blocked.

[0046]

As described above, according to the present invention, the door is opened.
A refrigerator that can be closed more smoothly can be provided.
