Abstract

A washing method capable of washing the laundry made of a fabric which is thin and shrinkable such as silks, wools, etc., simply at home without damaging the delicate fabrics and washing machine which is suitable for carrying out the above washing method. A detergent is introduced into a washing tank equipped with a rotary blade for generating a water stream and then a first amount of water suitable for diluting the detergent is introduced into the washing tank. Then, while rotating the rotary blade to generate a first water stream in the first amount of water, water is continuously introduced into the washing tank, so that the detergent is diluted in the first amount of water and that the washing tank is filled with a second amount of water suitable for washing the washing object. Then, the washing object is introduced into the washing tank with the second amount of water and then the washing object is washed by rotating the rotary blade for generating a second water stream suitable for washing the washing object. The rotation time of the rotary blade in the washing and rinsing steps is adjusted in accordance with the material of the washing object, so a water stream suitable for the washing object is generated in the washing and rinsing steps. A dry cleaning washing and silk washing courses can be simply performed at home without any damages to the laundry.
