Description

Door hinge for refrigerator {DOOR HINGE FOR REFRIGERATOR}

The present invention relates to a door hinge for a refrigerator, and more particularly, to a door hinge for a refrigerator, which can simultaneously open and close a refrigerator door opening and closing function by a slide pull-out type and a hinge pivot type by improving the door hinge structure.

Generally, a refrigerator is a device that keeps the food in a fresh state for a predetermined period by reducing the temperature of the refrigerating chamber and the freezing chamber as the refrigerant repeats a refrigerating cycle in which the refrigerant compresses - condenses - expands - evaporates.

The refrigerator includes a refrigerator body having a freezer compartment and a refrigerating compartment so that food can be stored in a low temperature state, and a refrigerator door that rotatably rotates the front surface of the refrigerator body.

In order to open and close the refrigerator door, one end is fixedly installed on the refrigerator main body, and the other end is connected to the refrigerator door to install a door hinge rotatably supporting the refrigerator door.

Since the door hinge according to the related art rotates the door hinge about an axis, the article stored in the pocket formed on the rear wall of the refrigerator door is located in the vicinity of the door hinge, and the refrigerator door is opened. Since it must be completely opened from the refrigerator body, there was a problem that the cold air outflow occurs seriously.

The present invention has been made to solve the above problems, an object of the present invention is to improve the door hinge structure to provide a door hinge for the refrigerator that can be combined with the sliding door pull-out and hinge pivoting together. have.

In order to achieve the above object, the door hinge for a refrigerator according to the present invention,

A first hinge shaft installed at one top and a bottom of the refrigerator main body;

A second hinge shaft disposed at an upper end and a lower end of the refrigerator door facing the first hinge axis;

It includes a connecting member for connecting between the first hinge axis and the second hinge axis,

The connection member is characterized in that the slide withdrawal stepwise in the direction of the force acting external force.

Here, the connection member,

A first connection part connected to the first hinge shaft and having a coupling hollow formed therein;

A second connection part drawn out from the coupling hollow of the first connection part;

And a third connection part connected to the second hinge shaft and drawn out from the coupling hollow of the second connection part.

In addition, the connecting member is characterized in that the pivoting in the left, right direction after the linear movement in accordance with the movement direction of the refrigerator door.

In addition, one side of the refrigerator door is characterized in that the pull-out opening and closing handle is formed to open and close the refrigerator door in the pushing or pulling direction.

According to the present invention, the connecting member connecting between the first hinge shaft and the second hinge shaft has a structure that can be pulled out step by step in the direction of the force acting external force, the refrigerator door at the time of taking out the article stored in the door hinge side It is possible to provide a certain open space by only pulling the not only can easily take out or put the goods, there is an effect that can prevent the bad waste of cold air is wasted.

1 is a plan view showing a door hinge for a refrigerator according to an embodiment of the present invention.
FIG. 2 is a plan view illustrating a drawing slide action of the door hinge of FIG. 1. FIG.
Figure 3 is a plan view showing the rotation after withdrawal by the door hinge for the refrigerator according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As illustrated, the door hinge for a refrigerator according to the present invention may include a first hinge shaft 210 installed at an upper end and a lower end of the refrigerator main body 100 and a refrigerator door facing the first hinge shaft 210. The second hinge shaft 220 is installed on one side upper end and the lower end of the 110, and the connection member 230 for connecting between the first hinge shaft 210 and the second hinge shaft 220.

First, the first hinge shaft 210 has a cylindrical structure which is installed on one side top and bottom of the refrigerator body 100.

In addition, the second hinge shaft 220 is installed at one upper end and the lower end of the refrigerator door 110 facing the first hinge shaft 210.

The first hinge shaft 210 and the second hinge shaft 220 are firmly fixed to the refrigerator body 100 and the refrigerator door 110, respectively.

On the other hand, the connecting member 230 is a configuration for connecting between the first hinge shaft 210 and the second hinge shaft 220.

Here, the connection member 230 is made of a structure capable of withdrawal step by step in the direction of the force acting external force.

That is, the connection member 230 connecting between the first hinge shaft 210 and the second hinge shaft 220 serves to open and close the refrigerator door 110 in a straight direction away from the refrigerator body 100. Make it work.

To this end, the connecting member 230 is connected to the first hinge shaft 210, the first connecting portion 231 and the coupling hollow is formed therein, withdrawal from the coupling hollow of the first connecting portion 231 And a third connection portion 232 connected to the second hinge shaft 220 and drawn out from the coupling hollow of the second connection portion 232.

That is, the first connecting portion 231, the second connecting portion 232, and the third connecting portion 233 may be formed in a structure in which the size of the diameter decreases in sequence so that the slide out may be stepped out.

The connection member 230 having the slide pull-out structure has the refrigerator door 110 when the article stored in the pocket formed on the rear wall of the refrigerator door 110 is located near the door hinge side and is taken out. It is possible to provide a certain open space by simply pulling the refrigerator door 110 without rotating the refrigerator body 100 in the direction of opening completely, it is not only easy to take out or put the goods, but also bad waste of cold air waste There is an effect that can be prevented.

In addition, it is preferable to further form a pull-out opening / closing handle 111 on one side of the refrigerator door 110 to open and close the refrigerator door 110 in a pushing or pulling direction.

Of course, the connection member 230 can be rotated in a left and right direction after the linear movement according to the movement direction of the refrigerator door 110.

Thus, according to the present invention, the connecting member 230 for connecting between the first hinge shaft 210 and the second hinge shaft 220 is made of a structure that can be pulled out step by step in the direction of the force acting external force Accordingly, when pulling out the article stored in the door hinge side, it is possible to provide a certain open space by simply pulling the refrigerator door 110, which can easily take out or put the article, and prevent the cold air from being excessively wasted. It works.
