Abstract

Disclosed is a control method of a washing machine comprising the steps of (a) setting a washing pattern in the present operation of the washing machine in consideration of hardness of the water calculated in the previous operation of the washing machine, (b) operating the washing machine based on the set washing pattern, and (c) calculating and storing hardness of the water in the present operation of the washing machine to set a next washing pattern in the next operation of the washing machine, thereby having the optimum washing or rinsing capacity of the washing machine in consideration ofdifferent characteristics of water by regional groups.

Description

Technical field [0001] The present invention relates to a control method of a washing machine, and in particular to a control method of such a washing machine, in which the hardness of the water provided to the washing machine is considered and the washing operation is performed based on an optimal washing mode. Background technique [0002] Generally, a washing machine is a device that uses electricity to provide mechanical actions to remove dirt from laundry. When laundry is put into water in which detergent is dissolved, dirt is removed from the laundry by the chemical action of the detergent. However, since it takes a long time to remove dirt from clothes only by the chemical action of detergent, it is easy to remove dirt from clothes by forcibly generating a rotating water stream or applying mechanical actions such as friction or vibration to the clothes. Things. [0003] The washing machine includes an outer tub, an inner tub rotatably located in the outer tub for accommoda...
