Abstract
A refrigerator having a basket lift apparatus comprises: a body having cooling chambers for storing food; a basket accommodated in the cooling chamber arranged at a lower portion of the body in a slidable manner back and forth; a basket lift apparatus installed at the basket, for lifting the basket when the basket is drawn out; and a break unit for locking the basket when the basket is lifted to the maximum and thereby preventing the basket from being descended. When the basket is lifted to the maximum, a driving motor is locked thereby to prevent the basket from being descended.
Claims22
A refrigerator comprising:
- a body having a cooling chamber;
- a door arranged at a front side of the cooling chamber;
- a basket arranged at the cooling chamber for storing food;
- a basket lift apparatus for lifting the basket, the basket lift apparatus including:
- a pair of lifting rails connected to the door;
- a lifting frame movably connected to each of the pair of lifting rails and on which the basket is positioned;
- a pair of driving arms, each driving arm being provided with a roller roll-mounted at a lower surface of the lifting frame at one end thereof, the pair of driving arms being connected by a hinge shaft extending therebetween, the hinge shaft being rotatably supported by a supporting frame fixed to a rear surface of the door;
- and
- a driving motor mounted at the door for rotating the pair of driving arms;
- and
- a brake unit for locking the basket and thereby preventing the basket from being lowered when the basket reaches a maximum position,
- wherein a distance between the connections of the lifting frame to the pair of lifting rails measured in a lateral direction of the door is greater than a distance between the pair of driving arms measured in the lateral direction of the door.
