Abstract

PURPOSE:To prevent deformation, damage of a fin and to complete a sealing effect of a refrigerator by attaching a fin extended obliquely from a gasket mounted at a door side so as to seal a gap formed between a rotary partition attached to one door and a body side guide. CONSTITUTION:A rotary partition 3 is attached to one 2a of a pair of doors 2a, 2b for closing a front surface opening of a refrigerator body 1. Fins 6a, 6b are respectively provided at a pair of gaskets containing magnets, and superposed to close a gap formed between a seat 4 of the body 1 and the partition 3. In this case, in order to seal the gap, it is so constructed that the ends of the fins 5a, 5b are not brought into contact with door end faces 8a, 8b. That is, the fins 6a, 6b are formed in a shape inclined at the inside of the refrigerator at the time of opening the door. When the door is closed, they are formed of an elastic material so deformed as to be brought into close contact with the same flat surface 10 formed of the partition 3, the seat 4 and the body 1.

2. Description of the Related Art The structure of a conventional door device for a refrigerator of this type will be explained with reference to FIGS. 5 and 6. The refrigerator main body 21 has a rotating partition 23 that forms the magnetized surfaces of the adjacent doors 21a and 21b, and the gap G created between both ends of the rotating partition 23 and the main body seat 24 is filled with a gasket attached to the door. 25a, 25
The fins 26a and 26b provided on the fins 26a and 26b are polymerized and sealed. In addition, when one door is closed, even if one fin is below the other fin, the amount of lap is small, and because the fins are formed thin, the fins will not be able to open and close the door. It is designed not to interfere with A conventional example of this type is JP-A-2-85681.

[Problems to be Solved by the Invention] The prior art described above does not take into consideration the distance between adjacent doors, and has the following problems.

(1) In order to seal the gap created between the rotary partition installed in the refrigerator main body and the main body seat, the fins provided on the gasket attached to the door side overlap each other so that the end face of the door There was a problem in that the fin end surface protruded more and the rotation locus created when the door was opened and closed hit the other door, causing damage and permanent deformation of the fin due to repeated door opening and closing operations, resulting in loss of its original sealing function.

(2) Also, in order to prevent the fin end surface from hitting the other door when opening and closing the door, it is possible to increase the distance between the doors so that the rotation locus does not come into contact with the other door. As the width of the partition increases, the opening area inside the refrigerator becomes smaller. Furthermore, the width of the storage section on the inside of the door has become smaller, reducing the effective utilization of the internal volume.

(3) Furthermore, in order to seal the gap created between the rotating partition and the main body seat, the fin was provided on the gasket only in that area. Therefore, although it is an elastic body, its area is small, so there are problems in that the restoring force is weak, the sealing performance is weak, and the moldability of the gasket is poor.

(4) Furthermore, handles and the like are often attached to the end face of the door for the sake of design, but since the handle and the like protrude from the end face of the door, the dimension between the doors becomes smaller, and the fins of the gasket are attached to the other side when the door is opened and closed. There was a problem that it easily hit the door handle, etc.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following features: (1) The shape of the fin of the gasket provided on the door side is inclined toward the inside of the refrigerator, so that the tip of the fin is By reducing the rotation trajectory created, the tip of the fin is prevented from hitting the other door, preventing damage and permanent deformation of the fin of the gasket, and perfecting the sealing effect of the refrigerator.

(2) Furthermore, since the tip of the fin protrudes smaller than the end face of the door, the distance between adjacent doors becomes smaller;
Since the width of the rotary partition is also smaller, the opening area inside the refrigerator becomes larger, and the width of the storage section on the inside of the door also becomes larger, which increases the effective utilization of the internal space and improves the appearance. It also improves effectiveness.

(3) Furthermore, by forming the fin to extend not only from the gap between the rotating partition and the main body seat but also from the upper end to the lower end of the gasket, the restoring force of the entire fin as an elastic body is increased. The sealing performance is increased, the process of partially cutting out the fin of the gasket can be omitted, and the processability is increased.

(4) Furthermore, even if a handle or the like is mounted to protrude from the end face of the door for design reasons, by cutting out the fin only at that part, damage to the fin and permanent deformation can be prevented without increasing the distance between the doors, and the refrigerator can be improved. Seal effect can be achieved.

0012

[Function] The fins of the gaskets provided on the adjacent doors are inclined towards the inside of the chamber when the doors are opened, and the door rotation locus created by the tip of the fins allows the door to rotate freely without coming into contact with the other door. It has become. In addition, when the door is closed, the fin is an elastic body, so while it comes into contact with the planar rotating partition and the catch surface, it gradually deforms and overlaps with the gasket fins of the adjacent door, and comes into close contact with the rotating partition and the catch. It is designed to seal any gaps that may arise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a sectional view of a main part of FIG. 2, FIG. 2 is a perspective view of a refrigerator, and FIGS. 3 and 4 are perspective views of main parts showing different embodiments of the present invention. First, explanation will be given based on FIG. 1. 1 is the refrigerator body, 2a and 2b are doors that close the front opening of the refrigerator body 1, 3 is a rotating partition attached to the door 2a, and the refrigerator body 1 is a door that allows the wide opening of the interior 1a to be used. The magnetized surfaces 10 of the magnet-containing gaskets 2a and 2b adjacent to each other do not have a fixed partition wall as in general commercially available refrigerators. The rotating partition 3 plays the role of the previous fixed partition. Although this rotating partition is not shown in the figure, by locking the pin provided on the rotating partition in the guide groove formed in the catch seat 4, the conventional example shown in FIG.
Move as shown. The pin 3a of the rotating partition 3 is
When the door 2a is opened and closed, a gap G shown in FIG. 6 is required between the rotating partition 3 and the seat 4 in order to move in and out of the guide grooves installed on the upper and lower sides of the refrigerator body. 5a and 5b are magnet-containing gaskets, and these gaskets 5a and 5b are provided with fins 6a and 6b as shown in FIG. This fin 6a
, 6b just wrap and close the gap G formed between the catch seat 4 and the rotary partition 3.

In this case, since the fins 6a and 6b overlap with the flat surfaces of the rotating partition 3 and the catch seat 4, the tips 7a and 7b of the fins 6a and 6b protrude from the door end surfaces 8a and 8b of the doors 2a and 2b. . Furthermore, when opening and closing the doors 2a and 2b, the fins 6
Rotation locus of tips 7a, 7b of a, 6b and door end surfaces 8a, 8
To explain the relationship between fin 6 and b using an example of the opening/closing operation of door 2b,
When the door 2b performs an opening/closing operation in a shape 6c (dotted line in the figure) with b remaining in the closed state, the rotation locus of the fin tip 7c becomes dimension M. Furthermore, the distance L from the rotation fulcrum 9 of the door 2b to the fin tip 7b
If the dimension and M dimension are larger than the distance N dimension from the fulcrum 9 to the other door end surface 8a, the tip 7b of the fin comes into contact with the other door end surface 8a during the opening/closing operation of the door 2b.

In the present invention, adjacent doors 2a and 2b have fins 7a provided on gaskets 5a and 5b in order to seal the gap G created between the seat 4 of the main body 1 and the rotating partition 3 attached to the door 2a. , 7b are invented so that they do not come into contact with the other door end surfaces 8a, 8b. That is, gaskets 5a, 5b
The fins 6a and 6b provided on the fins are formed in a shape that is inclined toward the inside of the refrigerator when the door is open, and when the door is closed, the rotating partition 3, catch seat 4, and main body 1
It is made of an elastic material so as to be deformed in close contact with the same plane portion 10 formed by the same plane.

The radius of rotation from the pivot point 9 of the door 2b to the tip 7b of the fin 6b, which is inclined toward the inside of the refrigerator, is L, and the radius of rotation of the fin 6b, which remains in close contact with the rotating partition 3, the catch seat 4, etc., is L. The rotation radius to the fin tip 7c (dotted line in the figure) is M, and the other door 2a
If the distance to the adjacent end face 8a is N, then the radius of rotation of the fin tip 7b, which is inclined toward the inside of the refrigerator, from the rotational fulcrum of the door is smaller than the fin tip 7c, which is not inclined, by dimension Q in the figure. In addition, since the distance from the rotation fulcrum to the other door end surface 8a can be made smaller than the distance from the rotation fulcrum to the other door end surface 8a, the fin end surface 7b of the gasket does not come into contact with the other door end surface 8a during the opening/closing operation of the door 2b, and the fin end surface 7b does not touch the other door end surface 8a every time the door is opened or closed. This prevents the tip from coming into contact with the other door and causing defects such as damage to the gasket fin or permanent deformation. The above is exactly the same regarding the relationship between the other door 2a and the gasket 5a and fin 6a provided thereon.

Furthermore, if the fins are formed to extend from the upper end to the lower end as shown in FIG. 4, the strength of the fins will increase, and the overlapping portion of the fins provided on the gaskets of adjacent doors will increase. This not only improves sealing performance, but also improves moldability.

Furthermore, a handle or the like installed on the door may protrude into the adjacent end surfaces 8a and 8b of the door. Even if the fins of the gasket are formed to be inclined toward the inside of the refrigerator, the gap between adjacent door end surfaces is usually narrow, so the tips of the fins often come into contact with protruding handles and the like. A notch is provided in the fin that comes into close contact with a flat surface other than the gap between the rotating partition 3 and the catch seat 4 to prevent it from coming into contact with the protruding handle, etc., to prevent damage and permanent deformation of the gasket fin during door opening/closing operations. I made it.

[0020]

[Effects of the Invention] According to the present invention, (1) By slanting the shape of the fin of the gasket toward the inside of the refrigerator, the protrusion of the tip of the fin from the end surface of the door becomes smaller when the door is opened, and when the door is opened and closed, The rotation trajectory created will not hit the other door, and damage and permanent deformation of the fins can be prevented.

(2) By reducing the protruding dimension of the fin, the gap formed by the opposing end surfaces of adjacent doors becomes smaller, so the width of the rotary partition also becomes smaller and the opening area inside the refrigerator becomes larger. Furthermore, since the width of the storage section inside the door is increased, the effective utilization of the interior volume is increased.

(3) Furthermore, by forming the fin on the rotating partition body not only in the gap between the body seats but also extending from the upper end to the lower end of the gasket, the restoring force of the entire fin as an elastic body is increased. Sealing performance is increased, and machining of the fins of the gasket with partial notches can be omitted, improving workability.

(4) Furthermore, even if a handle or the like is mounted to protrude from the end face of the door for design purposes, the fin can be cut out only in that area to prevent damage and permanent deformation of the fin without increasing the distance between the doors. A sealing effect can be achieved.
