Abstract

A drum type washing machine operates based on two washing processes. In the first process, a drum-shaped spin basket is rotated by 50 R.P.M. in forward and backward directions. Next, in the second process, the spin basket is rotated by 300 R.P.M. during about 20 seconds. Thereby, washing water contained in textiles is dewatered to outside of the spin basket. These first and second processes are repeatedly by specified times.
