Laundry machine and reuse method of washing water

Abstract

The present invention is a laundry machine for reusing detergent components contained in waste wash water. Water stored in an outer tub 5 during washing process and rinsing process is discharged from the outer tub 5 and introduced into a water storage tank 17 . By energizing an anode 19 and a cathode 20 to electrolyze the water stored in the water storage tank 17 , organic materials are deposited and separated and at the same time detergent components are separated and floated up. The separated detergent components are stored in a detergent container 30 , which are supplied into the outer tub 5 and reused during the washing process of the next washing.

Description

technical field [0001] The present invention relates to a washing machine in which water is stored in a washing tub for washing, and a method for reusing washing water. Background technique [0002] The washing machine includes a washing tank that can receive laundry and can store water in the washing tank for washing. At the time of washing, washing is generally performed by injecting detergent into the inside of the washing tank, and washing with water in which the detergent is dissolved. If the detergent is used for washing, the organic matter (stain) adhering to the laundry can be separated well, and the cleaning power can be improved. [0003] Most of the detergents sold on the market are the following synthetic detergents, which use surfactants such as sodium alkylbenzenesulfonate (ABS) and linear sodium alkylbenzenesulfonate (LAS) that are difficult to carry out biological treatment as main ingredient. In a common washing machine, since the water used for washing i...
