Laundry machine

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

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a laundry machine in which water is stored in a washing container and the laundry is washed in the washing container. [0003] 2. Description of Related Art [0004] A laundry machine has a washing container capable of loading the laundry and the laundry is washed in the washing container in which water is stored. At the time of washing, usually by putting a detergent into the washing container, the laundry is washed with the water in which the detergent is solved. If the laundry is washed with a detergent, organic materials (pollutants) attached to the laundry can be well separated and the detergency can be improved. [0005] Many of commercially available detergents are synthetic detergents containing surfactants as the main component such as sodium alkyl-benzene sulfonate (ABS) or sodium linear alkyl-benzene sulfonate (LAS) which is hard to be biologically treated. In a conventional lau...

AI Technical Summary

Benefits of technology

[0009] Another object of the present invention is to provide a laundry machine capable of realizing more economical washing.

[0011] Therefore, according to the present invention, wash water and a detergent can be reused, which is very economical and at the same time preferable from the viewpoint of environmental protection.

Problems solved by technology

The water discharge increases the burden of the water treatment in the sewage treatment plant and at the same time it is not preferable from the viewpoint of environmental protection.

However, in this prior art, though the detergent components contained in the waste water can be removed, there is a problem that the detergent components contained in the waste water cannot be reused for washing.
