LAUNDRY TREATMENT MACHINE

摘要

A laundry processor is provided to improve the washing performance regardless of the hardness of the water by controlling the washing time based on the measured hardness of the water. A laundry processor comprises a water supply part, a first sensor(51), a controller, a detergent supply part and a second sensor(52). The water supply part supplies the water to a tub from the outside. The first sensor is located at the water supply part in order to measure the conductivity of the water. The controller analyses the hardness of the water based on a conductance value and a control the washing time according to the hardness of the water. The detergent supply part supplies the washing water with detergent into the tub. The second sensor is arranged within the tub to measure the conductivity of the washing water put into the tub.
