Description

[Detailed Description of the Invention] This invention relates to a refrigerator in which the door gasket of a refrigerator or the like is improved so that the door closes with its own blade even when the door is slightly opened, and will be described in detail below according to one embodiment.

In FIG. 1, reference numeral 1 denotes a freezer compartment provided in the upper part of the refrigerator body, and a cooler 2, a blower device 3, etc. are installed on the back side.

Reference numeral 4 denotes a refrigerating room formed below the freezer compartment for storing refrigerated foods, which is connected to the freezing compartment 1 through a duct 5, etc., and is cooled by a cooler 2, an air blower 3, etc.

Reference numeral 6 denotes a freezer compartment door that closes the front opening of the freezer compartment 1, and a door gasket 7 is fitted around the opening.

Reference numeral 8 denotes a refrigerating compartment door, and a door gasket 7' is similarly installed around the refrigerating compartment 4.

Each door gasket 7,7' has a cross-sectional shape as shown in FIG.

That is, a flexible rubber magnet 11 made of, for example, a ferrite magnet bonded with a polymer binder is housed in a rectangular tube 10a of a door gasket body 10 made of a very flexible material such as soft vinyl chloride. has been done.

As shown in FIG. 4, the door gasket having such a cross section is composed of a horizontal side 7a and a vertical side 7b, and the connecting portions of the door gasket are welded and integrated.

The rubber magnets 11 of these door gaskets 7, 7' are attracted to the attraction surface 9 of the refrigerator body, thereby sealing each door and the refrigerator body.

The rubber magnet 11 that is housed on the horizontal side 7a of the door gasket has a stronger attractive force than the one that is housed on the vertical side 7b.

Reference numeral 12 denotes a bundle, and reference numeral 13 denotes a door hinge shaft, which is attached to the right side of the refrigerator body and supports the door so that it can be opened and closed.

In the refrigerator configured as above, for example, the freezer compartment door 6
When it is strongly closed after being opened, the air pressure in the freezer compartment 1 increases rapidly, and the air pressure in the refrigerator compartment 4, where the air passage is formed by the duct 5, etc., also increases, which causes the refrigerator compartment door 8 to open slightly. .

If we examine in detail the state where the refrigerator compartment door 8 is slightly open, the second
As shown in the figure, since the door gasket body 10 and rubber magnet 11 of the door gasket 7' have high flexibility, the hinge shaft 13 side is attracted to the attraction surface 9 by the rubber magnet 11, but the bundle 12 side is separated. It has become.

Therefore, according to this invention, since the door gasket 7a on the side side is equipped with a rubber magnet with a strong suction force, the refrigerator compartment door 9 is gradually closed by the strong suction force.

On the other hand, contrary to this idea, if the attraction force of the rubber magnet on the vertical side 7b of the door gasket is strengthened, for example, when opening the refrigerator compartment door 8, a strong force is required to open the door, making it difficult to use.

This is because when the handle 12 is sucked, all the vertical sides of the rubber magnets are simultaneously released from the attracted state, so that the door opening force becomes stronger.

However, when only the horizontal sides of the door gasket are strengthened as in this invention, as the vertical sides separate from the suction surface 9, the horizontal sides gradually separate, not just once, so the effect on the door opening force is very small.

As described above, according to this invention, the attraction force of the rubber magnet inside the door gasket is made so that the vertical side of the door gasket has just the right strength for the door opening force, and the horizontal side is stronger than that, so even if the door is opened a little, it will not cut automatically. It is extremely useful in practical terms, as it can be closed with a 2-inch switch, preventing unnecessary temperature rises, and saving electricity costs.

Note that the above explanation is based on the case of a two-door refrigerator, but 3
Of course, the same effect can be obtained in a multi-door refrigerator with more than one door, and it can also be applied to a single-door refrigerator to prevent the door from becoming open due to the reaction when the door is closed.

[Brief explanation of the drawing]

Figure 1 is a vertical cross-sectional view of a refrigerator in which this invention has been implemented, Figure 2 is a cross-sectional view taken along the line ■-■ of Figure 1, showing the door slightly open, and Figure 3 is the fourth cross-sectional view showing the door gasket. FIG. 4 is a front view of the door gasket. In the figure, numerals 7 and 7' are door gaskets, 11 is a rubber magnet, 7a is a horizontal side of the door gasket, and 7b is a vertical side of the door gasket.

Claims (1)

[Scope of utility model registration request] A door that freely opens and closes the opening of the refrigerator main body. This door is attached to either the left or right side of the main body using a hinge device, and flexible rubber magnets are used on the inside of the door corresponding to the periphery of the opening. A refrigerator equipped with a door gasket, characterized in that the rubber magnets used on the horizontal sides of the door gasket have a stronger attraction force than the rubber magnets used on the vertical sides.
