Description

[Detailed Description of the Invention] The present invention relates to an improvement of a refrigerator to improve the airtightness between the refrigerator body and the door.

Conventionally, a front opening of a refrigerator body is provided with a door that can be freely opened and closed, and a gasket having a magnet sealed in the upper surface is attached to the inner surface of the periphery of the door with screws or the like. This magnet sticks to the iron plate on the front of the refrigerator's opening, sealing the inside of the refrigerator. However, such a configuration has the drawback that cold air inside the refrigerator leaks to the outside through the gap between the door inner plate (runner) that constitutes the inner wall surface of the door and the refrigerator body, and the gap between the gasket attachment portion. Moreover, the process of packing and attaching the magnets requires time and effort, and the raw materials for the magnets are expensive, resulting in high manufacturing costs.

The present invention eliminates the above-mentioned drawbacks and provides a refrigerator that has good airtightness between the refrigerator body and the door and is inexpensive to manufacture.

Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, a door 1 has a space formed by an outer door panel 2 and an inner door panel 3 filled with a heat insulating material 4. The door inner plate 3 is made of hard synthetic resin, and has a protrusion 5 along the inner surface of the open end.
are integrally protruded. A thin bellow 6 made of soft synthetic resin is connected to the periphery of the tip of the convex portion 5. The convex portion 5 and the bellows 6 are integrally molded by two-color extrusion molding using hard and soft synthetic resins, respectively.

On the other hand, the refrigerator main body 7 is molded as a frame from hard synthetic resin, and has an opening on the front surface of the opening at a position opposite to the protrusion 5 into which the protrusion can be inserted, and has a cylindrical shape deeper than the length of the protrusion. A shaped groove 8 is provided. Groove 8
A cylindrical packing 9 made of soft synthetic resin is embedded inside. Packing 9 is groove 8
When molding, it is integrally molded by two-color extrusion molding using a soft synthetic resin that can be elastically deformed. 10 is a shelf.

With this configuration, when door 1 is closed,
The convex portion 5 presses the packing 9 from the outer periphery to deform it and is inserted into the groove 8. Next, the refrigerator main body 7 and the door 1 are fixed using a fixing handle (not shown) attached to the outside. At this time, Bella 6
If there is, the contact between the refrigerator body and the door will be more secure, and the circulation of cold air can be completely prevented.

As described above, according to the present invention, a protrusion is integrally provided on the door, a bellow is connected to the protrusion, the protrusion can be inserted into the refrigerator body, and the packing is buried. Since there is a groove provided between the door and the refrigerator body, there is good airtightness between the door and the refrigerator body, completely blocking cold air leakage. Easy to open and close the door. It can be made thinner by the thickness of conventional packing and magnets, and costs are reduced because expensive magnets are not used. There is no need to use an iron plate for the refrigerator body, so it has good heat insulation properties. Furthermore, since the door and the refrigerator body are integrally formed, assembly and manufacturing are easy.
