AI Technical Summary
Technical Problem
Existing water softeners generate a large amount of wastewater during the resin regeneration stage, resulting in water waste and low utilization rate.
Method used
Wastewater tanks and wastewater reuse circuits are set up. Wastewater is classified and stored according to ion concentration by solenoid valves. The opening degree of the solenoid valves is determined according to the current operating conditions and water volume ratio, and the wastewater is reused to the water supply circuit to provide part or all of the water source.
Benefits of technology
It reduces the water and salt consumption of the water softener, lowers the cost of salt replacement, improves wastewater utilization, and avoids water waste.

Abstract
This application discloses a wastewater utilization method and intelligent electrical appliance for a water softener. The water softener is equipped with a wastewater tank and a wastewater reuse water circuit. The method includes: responding to a wastewater reuse command, acquiring the current operating condition of the water softener and the target water volume corresponding to the current operating condition; the wastewater in the wastewater tank is obtained by recycling wastewater generated during the resin regeneration stage of the water softener; acquiring the current water level in the wastewater tank and determining the current water volume in the wastewater tank based on the current water level; calculating the ratio of the current water volume to the target water volume to obtain the current water volume ratio; determining the target opening degree of the solenoid valve based on the current operating condition and the current water volume ratio, and controlling the solenoid valve to transport wastewater from the wastewater tank to the water supply circuit at the target opening degree. This application can convert the wastewater generated by the water softener during the resin regeneration stage into usable brine and tap water, reducing the overall water consumption of the water softener and avoiding water waste.
