BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly, to a refrigerator including a shelf that is automatically drawn out or returned in association with an opening / closing operation of a door to be rotated.

Generally, a refrigerator discharges cold air generated by a refrigeration cycle including a compressor, a condenser, an expansion valve, an evaporator, etc. to lower the temperature of the inside of the refrigerator and freeze or refrigerate food or the like.

The refrigerator generally includes a freezer for freezing food or beverage, and a refrigerator for storing the food or beverage at a low temperature.

Such a refrigerator includes a top mount type in which a freezing chamber is disposed in an upper portion of a refrigerating chamber, a bottom freezer type in which a freezing chamber is disposed in a lower portion of the refrigerating chamber, and a freezing chamber in which a freezing chamber and a refrigerating chamber are connected to the left and right sides And a side by side type (side by side type).

In addition, a kimchi refrigerator for keeping food and vegetables such as kimchi fresh is also a kind of refrigerator.

At least one of the doors of the three types of refrigerators is connected to one side of the main body by a hinge and is rotated to open and close the main body.

The door pivoted by the hinge is mainly disposed on the upper side, and the drawer-type door, which is attached to the front of the drawer and pulled out or drawn in the front-rear direction together with the drawer, is mainly arranged in the middle or lower side.

The freezer compartment and the refrigerating compartment of the refrigerator are generally provided with a plurality of shelves for accommodating various sizes of food or the like and partitioning the storage compartment of the refrigerator up and down to increase space utilization.

However, since it is difficult to mount a plurality of shelves in the storage room in which the drawer type door is installed, it is common to install the shelves in the storage room in which the doors are opened and closed by the hinges.

Also, the shelf may be installed in a fixed position in the storage room and used in a fixed state, but a drawer provided on the shelf or the shelf may be installed to be pulled out in a forward and backward direction by a guide provided on both sides.

However, in order to remove the food or the like in the shelf or the drawer which is removably installed in the storage room by the user, the door to be rotated is opened and the shelf or the drawer is pulled out to take out the food. After removing the food, push the shelf or drawer back and close the door.

Particularly, in the case of frequently used food items, the door must be opened and the shelf or the drawer must be pulled out to take out the food in the inside, which is troublesome and uncomfortable for the user to use.

Also, it takes a lot of time to take out the food, and since the door is opened by that much, the loss of the cold is high.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator including a shelf that is automatically drawn out or returned in association with opening and closing operations of a door that is rotated.

To achieve the above object, according to a first aspect of the present invention, there is provided a refrigerator comprising: a main body having a storage chamber therein; A first door rotatably mounted on one side of the main body and opening / closing an opened front side of the main body; A second door rotatably mounted on one side of the first door to open and close an opening provided in the first door; A shelf provided in the storage room so as to be capable of being drawn out or pulled in forward and backward directions; And driving means provided between the second door and the shelf to draw or draw the shelf in the forward and backward directions as the second door is opened and closed.

The refrigerator according to the second embodiment of the present invention includes: a main body having a storage chamber therein; A first door rotatably mounted on one side of the main body and opening / closing an opened front side of the main body; A second door rotatably mounted on one side of the main body and opening / closing an opening provided in the first door; A shelf provided in the storage room so as to be capable of being drawn out or pulled in forward and backward directions; And driving means provided between the second door and the shelf to draw or draw the shelf in the forward and backward directions as the second door is opened and closed.

In addition, the driving means may include a flange fixed to one side of the inner surface of the second door and protruding to the front lower surface of the shelf, and a protrusion formed on an end of the flange, And a slot provided in the base.

Preferably, the projection formed at the end of the flange is mounted with a roller that rolls in the slot.

Further, on both sides of the shelf, guide rails for guiding the forward and backward movement of the shelves are preferably provided.

Further, the flange is preferably made of a metal material.

It is preferable that the shelf drawn or drawn in when the second door is opened or closed is a shelf provided at the lowermost side of the storage room among a plurality of shelves arranged vertically in the storage room of the refrigerator.

According to the refrigerator of the present invention, since the shelf connected to the door is automatically drawn or drawn as the door to be turned is opened or closed, the refrigerator can be conveniently used when the user takes out food or the like.

In addition, since the shelf is automatically drawn out and drawn in conjunction with the opening and closing operation of the door, it is possible to shorten the opening time of the door, thereby reducing the cold loss.

In addition, in the case of a shelf which is frequently opened by mounting the first door and the second door to the main body, only the second door can be opened to take out food or the like, thereby minimizing cold leakage.
