WATER QUALITY DISPLAY WASHING MACHINE

摘要

PURPOSE: A water quality display washing machine is provided to improve washing efficiency and save energy by easily checking the quality of water by displaying a detected value output from a plurality of sensors for sensing the quality of the water through a dual LED(Light Emitting Diode) formed at the exterior side to turn on and off a lamp with two colors. CONSTITUTION: A water quality display washing machine is composed of a sensing unit(100) for sensing the hardness and temperature of water and the amount of detergents; a display unit(300) turned on and off to the result detected by the sensing unit with changing the colors; and a microcomputer(200) for comparing the result sensed by the sensing unit with a pre-set standard value of the water and controlling the display unit to a compared result. The sensing unit comprises a hardness sensor(110) for sensing the hardness of the water; a detergent concentration sensor(120) for sensing the concentration of the detergent dissolved in the water; and a temperature sensor(130) for sensing the temperature of the water.
