Lifter and washing machine having the same

Abstract

A lifter simply mounted on a drum and a washing machine having the same. The washing machine includes a cabinet, a tub arranged within the cabinet, a drum arranged within the tub to accommodate laundry and rotated by rotary force transmitted from a driving source, and a plurality of lifters provided on the inner circumferential surface of the drum to move the laundry within the drum. Each of the plurality of lifters includes a plurality of hooks provided along a frame formed at the lower end of each of the plurality of lifters so as to allow each of the plurality of lifters to be hung to the drum, and at least one protrusion protruding from the lower end of each of the plurality of lifters so as to allow each of the plurality of lifters to be fixed to the inner circumferential surface of the drum.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 10-2011-0099069, filed on Sep. 29, 2011 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]Embodiments of the present inventive concept relate to a washing machine having lifters to lift and drop laundry in a drum.[0004]2. Description of the Related Art[0005]A washing machine is an apparatus which washes laundry using electric power, and generally includes a tub to store wash water, a drum rotatably installed within the tub, and a motor to rotate the drum.[0006]When the drum is rotated by the motor under the condition that laundry and wash water are placed within the drum, contaminants are removed from the laundry through friction of the laundry with the drum and the wash water.[0007]A plurality of lifters lifting and dropping the laundry during rotation of the drum to cause friction of th...

AI Technical Summary

Benefits of technology

[0010]It is another aspect of the present inventive concept to provide a lifter, the shape of which is changed to increase washing and drying efficiency of laundry, and a washing machine having the same.

[0017]The at least one protrusion may include at least one adhering protrusion adhering the plurality of hooks closely to the inner circumferential surface of the drum to increase fastening force between each of the plurality of lifters and the drum.

[0029]The at least one protrusion may include an adhering protrusion to increase mounting force of the plurality of hooks on the drum.

Problems solved by technology

If the fastening members are separately used, fastening time of the lifters to the drum may be lengthened and the overall price of the washing machine may be raised due to costs of the fastening members.
