Benefits of technology

[0011] Accordingly, it is an aspect of the present invention to provide a washing machine capable of preventing a magnet from being removed from a predetermined position even when the washing machine has been used for a lengthy period of time.

Problems solved by technology

Thus, the conventional washing machine has a problem in that a strength of the adhesive is weakened when vibrations caused by operations of the washing machine have been transmitted to the magnet for a lengthy period of time, and thereby the magnet may be removed from the predetermined position of the power transmission unit.

Abstract

A washing machine capable of preventing a magnet, which detects a number of rotations of a washing shaft, from being removed from a predetermined position. The washing machine includes a drive motor to generate a rotating force. A washing shaft is rotated by the drive motor. A belt and a shaft pulley transmit the rotating force from the drive motor to the washing shaft. A magnet is mounted to the shaft pulley to rotate along with the shaft pulley. A magnetic sensor detects a number of rotations of the washing shaft, in response to a change in a magnetic field produced by the magnet. A locking unit is mounted at a first end thereof to the magnet, and at a second end thereof to the shaft pulley. Therefore, even when the vibrations caused by operations of the washing machine are transmitted to the magnet for a lengthy period of time, the magnet is connected to the shaft pulley by the locking unit without being removed from a predetermined position.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 2003-72929, filed on Oct. 20, 2003 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
