PURPOSE: A water quality state display washing machine is provided to improve the washability and the efficiency of a washing stroke by making values sensed by plural sensors displayed via a dual LED(Light Emitting Diode) with color classification of colors and circulating blinking, to enable a user to easily recognize the state of the quality of washing water. CONSTITUTION: A water quality state display washing machine comprises a sensing unit(100) sensing the hardness of washing water, the quantity of a detergent, and temperature; a display part(300) turned on and off with classification and mixing of colors according to the result sensed from the sensing unit; and a microcomputer(200) comparing the result sensed from the sensing unit with a predetermined standard range of the washing water state and controlling the display part according to the compared result. The display part comprises a dual LED(310) emitting light in one color, different colors, or mixed colors according to a control signal of the microcomputer. |
