摘要:
An aspect of the present disclosure is to provide a washing machine that detects contamination of water due to a dye and prevents contamination of laundry due to the dye. The washing machine includes a tub; a drum configured to be rotatable inside of the tub; a detergent supplier configured to supply a detergent to the tub; a water supplier configured to supply a water to the tub; an optical sensor provided under the tub, wherein the optical sensor includes a light emitting element and a light receiving element configured to selectively receive a plurality of visible rays having different wavelengths and an infrared ray among a light emitted from the light emitting element; and a controller configured to control the water supplier to supply the detergent and the water to the tub and rotate the drum during a washing. In addition, the controller may reduce the washing time based on the sum of the received intensities of the plurality of visible rays and the received intensity of the infrared ray.
