AI Technical Summary

Technical Problem

Existing water hardness adjustment systems for wash basins in hair salons are limited to binary choices between softened and unsoftened water, failing to adapt to the varying needs of different hair treatments, and lack real-time adjustment capabilities.

Method used

A proportional 3-way distribution valve with continuous adjustability and motorized control, combined with water hardness sensors, allows for precise adjustment of water hardness between 0 and 100% through a wash basin system, enabling real-time monitoring and automatic regulation based on sensor data.

Benefits of technology

Enables flexible and precise control of water hardness for different hair treatment phases, enhancing shampoo lather, hair texture, and care by optimizing water properties according to specific treatment requirements.

Abstract

Water hardness adjustment system for a wash basin, particularly in hair salons. This application relates to a water hardness adjustment system (3) for a wash basin (10), particularly in hair salons, comprising a water supply line (21) connected to a distribution valve (4) between a first branch (a) connected to a water inlet of a water softener (1) and a second branch (b) bypassing the softener, the second branch joining an outlet of the softener (c) to a mixing tee (d), the system being characterized in that the distribution valve is adjustable to at least one position between 0 and 100% water to one of the branches.
