Problems solved by technology

Divalent calcium ions, magnesium ions and dirt combine to form insoluble salts, making stains more difficult to remove
It is also a waste if all the water is softened by the softening device regardless of whether it is hard water or not.

Abstract

A method for controlling water hardness of washer is used for automatic washer with ion-exchange resin water softener and controller. The process is carried out by inspecting water hardness by inspector, controlling softened-water electromagnetic valve, softened-water discharge electromagnetic valve and water-intake pipe electromagnetic valve turnoff / turn-on, passing running-water into washing drum or passing into washing drum by water softener, ion-exchange resin salt brine reclaim treating, recording treating time by controller, accumulating, displaying, storing, alarming while reaching accumulation end to a certain value, reminding users to add into salt and judging running-water hardness. It saves resources and has better softened water quality.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine with a hardness control device and a water hardness control method. Background technique [0002] Hard water will reduce the efficiency of the detergent. When the laundry water contains cations such as divalent calcium ions and magnesium ions as water hardening components, these calcium ions and magnesium ions will react with the surfactant in the detergent to form insoluble metals. Soap, reduces the amount of surfactants that are good for laundry and reduces stain release. Clothes washed in hard water look dark and sloppy, and feel rough and stiff to the touch. Divalent calcium ions, magnesium ions, and dirt combine to form insoluble salts that make stains more difficult to remove. And the dirt on the clothes introduces more invisible minerals into the wash water, making the water harder. Washing clothes in hard water can also damage the fibers of the garment, reducing t...
