Abstract
A clothes washing machine comprises a water container and a washing tub disposed in the water container to form a space therebetween for containing wash water. A tourmaline ceramic coating is applied to an outer bottom surface of the washing tub or to an inner surface of the water container for reacting with the wash water to form hydroxyl ions therein which reduce surface tension of the water. An ultrasonic vibrator is mounted on the water container across from the coating to generate waves in the water to accelerate the reaction between the coating and wash water. Alternatively, the tourmaline ceramic coating could be applied to an agitator disposed in the washing tub.

A clothes washing machine comprising:
- a water container;
- a wash tub disposed in said water container to form a space therebetween for containing wash water;
- a tourmaline material disposed in said space for reacting with the wash water to form therein hydroxyl ions for reducing surface tension of the wash water;
- and
- wave generating means communicating with said space for generating waves in the wash water in the vicinity of said tourmaline material for accelerating the reaction between said tourmaline material and the wash water.
A clothes washing machine comprising:
- a water container;
- a wash tub disposed in said water container such that an internal surface of said water container is spaced from an external surface of said wash tub to form a space therebetween for containing wash water;
- and a tourmaline material disposed in said space for reacting with the wash water to form therein hydroxyl ions for reducing surface tension of the wash water.
A clothes washing machine comprising:
- a water container;
- a wash tub disposed in the water container;
- an agitator disposed in the wash tub;
- and
- a tourmaline material affixed to said agitator for reacting with the wash water to form therein hydroxyl ions for reducing surface tension of the wash water.
