Problems solved by technology

In this case, because there is a significant difference between the force required to separate the liner and the force required by the revolving door, an oversized actuator is necessary, which is inefficient
In addition, since refrigerators are required to have increased space to accommodate large actuators, it is difficult to provide this increased space without compromising the size or thermal insulation performance of conventional refrigerators.

Abstract

A door opening and closing device for a refrigerator includes a door coupled by means of a hinge unit to a main body defining a storage compartment therein, a gasket disposed between the door and the main body to provide a hermetic seal therebetween, and an opening and closing unit for opening and closing the door with respect to the main body, wherein the opening and closing unit includes a drive unit for generating a driving force, a gasket separation mechanism for pushing the main body using rotational force transmitted from the drive unit to separate the gasket from the main body or the door, and a door rotating mechanism for rotating the door using the rotational force transmitted from the drive unit.

Description

Technical field [0001] The invention relates to a door opening and closing device for a refrigerator. Background technique [0002] Generally, a refrigerator is a device for storing objects to be kept in a fresh state for a long period of time using cold air supplied into a storage room. The cold air supplied into the storage chamber is generated by heat exchange with the refrigerant. The cold air supplied into the storage chamber is evenly distributed throughout the storage chamber by convection so that food can be stored at a desired temperature. [0003] The storage compartment is defined in the main body forming the appearance of the refrigerator. The storage compartment is opened at its front so that food can be received through the opening. A door for opening and closing the storage room is installed at the front of the storage room. The door is hinged to the main body to open and close the storage compartment. [0004] In order to prevent cold air from leaking to the outs...
