Abstract
The refrigerator is a lower hinge for rotatably supporting the door. The lower hinge rotatably supports the door. The hinge plate connects the door to the door. The rotary shaft is inserted into the lower portion of the door so that the door rotates. As shown in Fig.
Description
The present invention relates to a refrigerator having a first door rotatably provided to open and close a storage compartment and having an opening, at least one door pocket provided in the opening, and a second door rotatably provided to open and close the opening will be.
Generally, a refrigerator is a household appliance that can store food for a long time with freshness by having a storage room for storing food and a cold-air supply device for supplying cold air to the storage room.
There is a shelf in the storage room, so you can put food on it. The storage room may be opened to open and close the food storage container, and the open front of the storage room may be opened and closed by a first door rotatably coupled to the main body. A door pocket for storing food may be provided on the rear surface of the first door, separately from the shelf disposed in the storage room.
Since the door pockets are provided on the rear surface of the first door, generally the first door is opened to allow access. Meanwhile, there is a refrigerator in which a separate second door is provided in the first door so that the door can be accessed without opening the first door. The refrigerator having the second door can open the second door only without opening the door to access the door pocket provided on the rear side of the door, so that the variety of food storage can be improved and the effect of preserving the cold air can be obtained.
However, since the second door has a limited size, it is possible to access only a part of the door pockets of the plurality of door pockets provided up and down on the rear surface of the first door.
One aspect of the present invention discloses a refrigerator that can access both a plurality of door pockets provided in a first door by opening only a second door without opening the first door.
According to an aspect of the present invention, a refrigerator includes a main body having a storage chamber; a door rotatably provided to open and close the storage chamber; And an upper hinge rotatably supporting the door, a lower hinge; Wherein the lower hinge comprises: a hinge plate having a fixed portion coupled to a lower surface of the main body and an extended portion extending downward of the door; and a hinge plate coupled to the extended portion of the hinge plate, A hinge shaft inserted in a lower portion of the door and having a flange extending in a radial direction to receive a load of the door, a support cap contacting the ground, and a hinge shaft extending perpendicularly to the hinge shaft, And the support shaft is axially screwed to the hinge shaft.
Here, a female screw portion may be formed on the inner circumferential surface of the hinge shaft, and a male screw portion may be formed on the outer circumferential surface of the support shaft to be screwed to the female screw portion of the hinge shaft.
Further, the height of the door can be adjusted by varying the amount of screw engagement between the support shaft and the hinge shaft.
Further, the support leg can be separated from the hinge shaft.
Further, the load of the door applied to the hinge shaft can be transmitted directly to the ground through the support shaft coupled to the hinge shaft, and the sagging of the hinge plate can be prevented.
Further, the hinge shaft may be integrally formed.
The door may further include an auto closure provided between the door and the flange of the hinge shaft to rotate the door in a completely closed direction when the door is closed by a predetermined angle or more.
According to another aspect of the present invention, there is provided a refrigerator comprising: a main body having a storage compartment; a rotatably provided front portion of the main body to open and close the storage compartment; an opening having a first door pocket; A second door rotatably provided in front of the first door to open and close the opening and to rotate in the same direction as the rotation direction of the first door; A first phase hinge, and a first lower hinge; And a second upper hinge rotatably supporting the second door; a second lower hinge; And the first lower hinge includes support legs contacting the ground to support the load of the first door.
The first lower hinge includes a hinge plate coupled to a lower surface of the main body and extending to a lower side of the first door and a hinge shaft inserted into a lower portion of the first door to rotate the first door, The support leg may have a support shaft formed coaxially with the hinge shaft.
Here, the support shaft may be screwed to the hinge shaft.
Here, a female screw portion may be formed on the inner circumferential surface of the hinge shaft, and a male screw portion may be formed on the outer circumferential surface of the support shaft to be screwed to the female screw portion of the hinge shaft.
According to the idea of the present invention, it is possible to prevent the lower hinge from sagging due to the load of the food stored in the door and the door.
