The present invention relates to a door opening and closing device and a storage cabinet including the same, and more particularly, to open and close the door of a storage cabinet for storing kitchen appliances, etc., up and down, maintaining the door in a horizontal and vertical state, and preventing damage to the door. It relates to a door opening and closing device and a storage cabinet having the same.

As the standard of living of modern people has increased, the kitchen has been expanded from the concept of a simple place to eat and recognized as one of the important living spaces in the home. Accordingly, kitchen furniture such as dining tables, sinks, cupboards, and storage cabinets have been developed in a way that makes the life of housewives more convenient while having a luxurious interior effect according to the user's demand level.

Recently, storage furniture for kitchens is rapidly shifting away from the concept of simply storing dishes or utensils to the concept of a new and independent storage space. That is, various types of kitchen furniture are being manufactured so that various electronic products such as refrigerators are stored in storage cabinets, and kitchen utensils such as microwave ovens and rice cookers can be stored.

For example, a lift door for kitchen furniture was developed to open and close the front of the kitchen furniture prepared to store kitchen utensils, and a gas shock absorber is installed so that the user can hold the door handle and move it at a certain angle or more. It is manufactured in a semi-automatic form that allows it to open and close automatically when moved.

One example of this technique is disclosed in Documents 1 to 3 below.

For example, Patent Document 1 below includes a door with a lower end that pivots and moves vertically with respect to the frame body of the appliance via at least a connecting rod when a household appliance such as a double oven range is moved between a closed position and an open position, A pivot arm hinged to the cabinet and the door, a slider mechanism and a connecting rod hinged to the cabinet and the door at a distance from the pivot arm, and a multi-joint hinge having a structure in which the hinge mechanism opens and closes the door horizontally and vertically. A household appliance including a door mounted via a mechanism is disclosed.

In addition, in Patent Document 2, a door located on the open front of kitchen furniture, a door bracket installed on the rear side of the door, a mounting bracket installed on the inner side of the furniture, and the door can be raised or lowered during opening and closing. A pivoting frame, both ends of which are rotatably installed on the door bracket and the mounting bracket, a gas shock absorber installed between one end of the pivot frame and the mounting bracket to semi-automatically open and close the door, and a path in which the gas shock absorber rotates Disclosed is a lift door for kitchen furniture including a shock absorber installed thereon.

On the other hand, in Patent Document 3, a screw thread is formed at the bottom, a first bracket coupling portion for bracket coupling is formed at the top, a body having a hollow inside, a shaft and an upper end part of which are inserted into the body It is fastened to the body to connect the shaft and the body, and a connection socket composed of a receiving part formed with an entrance hole for penetrating the shaft and a corresponding fastening part formed to be connected to the top of the receiving part and screwed together with the fastening part of the body Disclosed is a bottom-up door opening and closing device including.
