Abstract
A refrigerator includes a main door rotatably provided in the cabinet by a first hinge to open and close the storeroom, and a sub door disposed between the main door and the storeroom, rotatably provided with respect to the main door by a second hinge, and defining a storage space disposed inside the storeroom in a closed state, and in this case, the first hinge and the second hinge are bent at the same bending angle and are disposed in parallel to each other or overlap each other.
Claims29
A refrigerator comprising:
- a cabinet including a first storage space therein;
- a main door rotatably coupled to the cabinet by a first hinge and configured to open and close the first storage space;
- and
- a sub door positioned between the main door and the first storage space, rotatably coupled to the main door by a second hinge, and defining a second storage space disposed inside the first storage space when the sub door is closed,
- wherein:
- the first hinge includes a first end coupled to the cabinet and a second end coupled to a first section of a pivot shaft of the main door such that the main door rotates with respect to the cabinet;
- and
- the second hinge includes a first end coupled to the sub door and a second end coupled at a second section of the pivot shaft such that the sub door rotates with respect to the main door,
- wherein the first end and the second end of the second hinge are connected by a vertical extension such that the first end and the second end of the second hinge are provided at different vertical heights of the refrigerator,
- wherein a second cover is disposed on the second hinge, and wherein the second cover includes a coupler bent in a vertical direction such that the coupler overlaps and combines with the vertical extension of the second hinge.
