Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator, and more particularly, to a refrigerator including a main body having a storage compartment for receiving food and a door coupled to the main body to open and close the storage compartment, and more particularly, to a kimchi refrigerator.

In general, a refrigerator includes a main body including a storage compartment accommodating food and a storage container and a machine compartment formed to appropriately cool the temperature of the storage compartment, and a door coupled to one side of the main body to open and close a door opening of the storage compartment. In particular, the basic principle of the refrigerator is the kimchi refrigerator used to ripen and freshly store kimchi, the main body including a storage compartment formed with a space for accommodating the storage vessel for storing kimchi and a machine room for appropriately cooling the temperature of the storage compartment. And, coupled to one side of such a body includes a door for opening and closing the door opening of the storage compartment. In addition, the door of the kimchi refrigerator is attached to the upper surface of the main body in order to minimize the leakage of cold air is preferred to open and close the door opening of the storage compartment.

Hereinafter, a kimchi refrigerator equipped with such an upward opening door will be described as an example.

1 is a perspective view of a conventional kimchi refrigerator, the kimchi refrigerator 1 has a main body 10 and a door 11 attached to an upper portion of the main body 10 to open and close the door opening of the storage compartment 13.

FIG. 2 is a cross-sectional view of FIG. 1, in which the main body 10 appropriately cools the temperature of the storage chamber 13 accommodating the storage container 15 inside the main body 10 and the storage chamber 13 under the storage chamber 13. It has a machine room 17 formed to make it.

As the kimchi refrigerator is enlarged to secure more storage space of the storage compartment, the width and depth of the storage compartment are increased, and the storage vessel accommodated in the storage compartment is also enlarged. Accordingly, it is difficult for a user to directly lift a heavy storage container accommodated in a lower portion of a wider storage compartment.

Therefore, the storage vessel raising device of the kimchi storage is disclosed in Korean Patent Publication No. 01-0028446. The storage device lifting device of the kimchi storage container is formed on the bottom of the kimchi storage container on the support plate to form a plurality of springs to apply an elastic force, so that when the door is closed, descends to the lower side, and when the door is opened, it rises by the elastic force It is characterized by the configuration.

However, the kimchi storage device attached to the storage container raising device using only the elastic force of the spring has to use a high elastic spring material as the storage container is heavy, there is a problem that the spring must be compressed only by the user's force when closing the door. In addition, when the door is opened, the storage container rises only by the elastic force of the spring, and the rising width is changed according to the weight of the storage container. When the storage container is heavy, the rising width is relatively small. There is a problem that can not be raised.

Accordingly, an object of the present invention is to provide a refrigerator capable of easily raising a storage container accommodated in a storage room by a desired position.
