Description

Refrigerator {Refrigerator}

The present invention relates to a refrigerator.

Generally, a refrigerator is a household appliance for storing food at a low temperature.

In the refrigerator, a plurality of shelves are vertically arranged at predetermined intervals, and drawer-shaped storage boxes can be arranged.

The food stored in the shelf may be stored in a container with a low height such as a bowl, but it may be stored in a long container such as a beverage bottle.

In this case, the container, which is longer than the interval between the shelves and the shelves, is inconveniently incapable of being housed in the storage compartment. In order to solve this problem, in general, the interval between adjacent shelves is increased, or the long container is housed in a basket provided in the door.

In order to adjust the distance between the shelves and the shelves as described above, it is inconvenient to remove all the food stored on the shelves, and then remove the shelves and install them at different positions.

According to the refrigerator disclosed in the following prior art, a part of the shelf is rotatable in order to solve the problem mentioned above, so that the container having a long length can be effectively housed.

Korean Patent Publication No. 10-2016-0005688 (Jan. 15, 2016)

However, in the case of the shelf structure disclosed in the above-mentioned prior art, the stopper structure that prevents the shelf from rotating further in a state where the shelf is rotated vertically is not clearly disclosed.

The stopper described in detail and in the drawings serves to prevent the shelf from being pulled out in the state in which the shelf is rotated or to prevent the shelf from rotating in the drawn-out state, And the like are not explicitly disclosed.

Therefore, in the case of the shelf disclosed in the prior art, there is a problem that, when the user releases his / her hand from the shelf after the shelf is rotated in the vertical state, it can be rotated to the original position or rotated further in the vertical state.

In addition, when the shelf is rotated in a horizontal state, a glass material shelf may be damaged due to impact, or a bottle or a shelf may be damaged due to a collision with a storage container such as a bottle.

SUMMARY OF THE INVENTION The present invention is proposed to solve the above problems.

According to an aspect of the present invention, there is provided a refrigerator comprising: a cabinet having a storage chamber formed therein; And a shelf assembly mounted on the inside of the storage chamber, wherein the shelf assembly includes: a shelf support portion fixed to a rear surface of the cabinet; a fixed shelf mounted on an upper surface of the shelf support portion; The hinge assembly includes a hinge bracket mounted on the shelf support portion and having a left hinge shaft and a right hinge shaft extending therefrom, and a hinge bracket attached to the hinge bracket, A rotating hinge shaft extending from a side surface of the rotary shelf so as to be positioned between the left hinge shaft and the right hinge shaft and inserted through the left hinge shaft and the rotating hinge shaft and the right hinge shaft, And a hinge pin serving as a center of rotation of the shelf, wherein one of the left hinge axis and the right hinge axis A first stopper for limiting the rotation of the rotary table is extended to the side surface of the rotary table, and the first stopper is provided on the side surface of the rotary table when the rotary table is rotated by a set angle, .

The refrigerator according to the embodiment of the present invention configured as described above has the following effects.

First, when the space between the shelf and the shelf is shorter than the length of the storage container, there is an advantage that a long storage container can be effectively accommodated by rotating a part of the shelf about the longitudinal axis of the refrigerator.

Second, the stopper is provided on the rotary shaft of the rotary type shelf, so that the shelf which is rotated upward to be lifted upward can be maintained in a vertical state. As a result, it is possible to prevent the shelf from colliding with the storage container while being rotated in a horizontal state, or colliding with the upper surface of the fixed shelf to be broken.

A return preventing stopper 238 may be formed to protrude from a point adjacent to the hinge shaft 237.

More specifically, the return preventing stopper 238 functions to hold the raised stopper 238 in a standing state without returning to the original position even when the holding hand of the rotating shelf 23 is released, in a state in which the turning stopper 23 is rotated and lifted. If there is no return preventing stopper 238 and the hand holding the rotary shelf 23 is released while the rotary shelf 23 is rotated at an angle smaller than 90 degrees, Can be reversed and fall back to the original position. Then, if the rotating shelf plate 236 is made of a channel, it can be broken. The return preventing stopper 238 is provided to prevent such a phenomenon.

The return preventing stopper 239 includes an extended portion 238a extending horizontally from the side of the right frame 233 and a bent portion 238b bent downward from the end of the extended portion 238a can do. The return preventing stopper 238 may be designed to have a slight elastic force.

On the other hand, when the hand holding the rotary shelf 23 is released in a state in which the rotary shelf 23 is rotated 90 degrees or more while the rotary shelf 23 is horizontal, 23) is further prevented from rotating due to its own weight.

The over-rotation preventing stopper 239 may include an extension portion 239a extending horizontally from the side surface of the right frame 233 and an extension portion 239b formed at an end portion of the extension portion 239a have.

Fig.

11 and 12, when the length of the food container is larger than the distance between the upper and lower adjacent shelves, the rotary shelf 23 rotates to be vertical and is rotated by the rotary shelf 23 So that the shielding opening 225 is opened.

The food container is placed on the top surface of the shelf located below the shelf assembly 20, which is located directly below the opening 225. There is then an advantage that it is not necessary to separate either the upper or lower shelf to adjust the height of the shelf above or below.

Referring to FIG. 13, when the rotary shelf 23 is rotated and lifted, the return preventing stopper 238 rotates together with the rotary shelf 23. The bent portion 238b of the return preventing stopper 238 rides over the step portion 244 and is finally caught on the bottom surface of the step portion 244. [ The return preventing stopper 238 is resiliently deformed slightly when it rides over the step portion 244 and is restored to its original position as soon as the bent portion 238b is caught by the bottom surface of the step portion 244 . In this state, even when the hand holding the rotary shelf 23 is released, the rotation of the rotary shelf 23 does not occur to the original position.

14, the extended portion 239a of the over-rotation preventing stopper 239 is in a state in which the gap G3 (see FIG. 14) formed between the second lateral extending ends 252, . The right side surface of the rotating shelf 23 faces the upper surface of the second lateral extending ends 255 and 258.

The extended portion 239b of the over-rotation preventing stopper 239 is in contact with the longitudinal extension 253 of the left extension 255 and the longitudinal extension 257 of the right extension 259, The turning shelf 23 can no longer rotate.

Thus, even if the user releases his or her hand from the rotating shelf 23 by the return preventing stopper 238 and the overrunning stopper 239, the rotating shelf 23 is moved from the vertical position to the left or right Do not rotate.
