Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator.

A refrigerator is a household appliance used for storing food in a refrigerated state or in a frozen state.

In recent years, the capacity of the refrigerator is becoming larger, and a home bar, an ice maker, a shelf or a door box is mounted on the back of the refrigerator door. In the case of this type of refrigerator, when a refrigerator door is closed, there is a possibility that a shelf or a drawer mounted in a storage room of the refrigerator main body and constituent parts mounted on the back surface of the refrigerator door may interfere with each other.

In order to solve such an interference problem, a front end of a storage compartment (for example, a shelf or a drawer) of a refrigerator main body, that is, a refrigerant compartment or a freezer compartment, is retracted a predetermined distance from the front surface of the refrigerator main body Lt; / RTI >

Therefore, it is inconvenient for the user to insert his or her hands deeply into the storage room in order to retrieve the food stored in the storage compartment, and it is difficult for the user to confirm the food stored in the rear of the storage compartment. This problem becomes larger as the storage room becomes deeper as the refrigerator becomes larger.

Various methods have been proposed to overcome such disadvantages. Particularly, Korean Patent Publication No. 2010-0130357 (hereinafter referred to as " 357 patent ") filed by the applicant of the present invention is characterized in that a shelf or a drawer installed in a refrigerator compartment or a freezer compartment is placed on a storage frame, And the rear end portion is connected to the receiving frame. Accordingly, when the refrigerator door is rotated and opened, the shelf and the drawer move forward of the refrigerator while the storage frame moves forward.

In the case of the refrigerator having such a structure, the load of the shelf and the drawer is transmitted to the housing frame. In other words, the storage frame has a structure in which both the load of the shelf and the drawer, and the load of the food stored in the shelf and the drawer are concentrated in the storage frame, and therefore, the structure of the storage frame is designed Therefore, the structure of the housing frame is complicated, the volume is increased, the weight of the housing frame itself is not only heavy but also the space occupied by the housing frame reduces the volume of the storage chamber accordingly.

In addition, in the case of the '357 patent, since the link for moving the storage frame in cooperation with the door is connected to the lower surface of the storage frame, the point of action of the force applied through the link is located on the lower surface of the storage frame, Is centered on the lower side of the lower surface of the housing frame. Therefore, a line of action of the force by the link and a line of action of force by the inertia of the drawer do not exist in the same line, so that a bending moment or a shearing force acts on the receiving frame to cause deformation of the receiving frame , This phenomenon becomes worse as the weight of the stock in the drawer increases. In particular, in the case of the '357 patent, since the load of the drawer is supported by the housing frame, the load acting by the drawer causes the deformation of the housing frame to be further promoted along with the inertia of the drawer.

In addition, in the case of the '357 patent, since the load applied from the housing frame is concentrated on the rails provided on the lower surface of the housing frame, the rails must be always kept in normal operation. However, in the ' 357 patent, it is practically limited to design a rail having sufficient durability within a specified standard.

Further, the structure in which all loads applied from the storage frame are concentrated on the rails makes it possible for the storage frame to be easily moved between movements. If the rails or the receiving frame are deformed by such shaking, the moving operation of the receiving frame can not be performed stably.

Japanese Patent Laid-Open Publication No. JP2004-93039A (hereinafter referred to as the '039 patent) discloses a refrigerator in which a shelf provided in a storage room is connected to a door by an arm so that the shelf is drawn out by the arm when the door is opened have.
