Intelligent water softener and control method thereof

Abstract

The invention provides an intelligent water softener and a control method thereof. The water softener comprises a water inlet pipe, a water softening pipe, a brine pipe, a water discharging pipe, a salt tank and a resin tank, the water inlet pipe, the water softening pipe and the water discharging pipe are connected with the resin tank, and the brine pipe is connected between the salt tank and theresin tank; the water inlet pipe is provided with an influent water flow sensor, an influent water quality sensor and a water inlet solenoid valve in sequence in the direction of the resin tank; thewater softening pipe is provided with a soft water solenoid valve and a soft water quality sensor in sequence in the direction of the resin tank; a bypass solenoid valve is connected between the influent water quality sensor of the water inlet pipe and the soft water quality sensor of the water softening pipe; the brine pipe is provided with a salt tank solenoid valve, a reclaimed brine quality sensor and a reclaimed brine flow meter; and the water discharging pipe is provided with a discharged water quality sensor. The water softener provided by the invention realizes instant response to change of water quality through the intelligent sensors, and makes the corresponding intelligent adjustment to the softening process, the regeneration process, the backwashing and the washing process in real time according to change of water quality.

Description

technical field [0001] The invention relates to a domestic and commercial water softener and a control method for its operation, which is an intelligent complete set of equipment based on the integration of the Internet of Things and artificial intelligence. Background technique [0002] The high hardness of tap water will cause fouling of water containers such as electric kettles, dishwashers, water heaters, and heating pipes. In addition, due to the high content of calcium and magnesium ions in water, the decontamination effect of detergents (such as detergent, shampoo, shower gel, laundry detergent, etc.) will be reduced, resulting in increased consumption of detergents. In order to solve this high water hardness Many families soften the tap water by installing a water softener. [0003] Existing domestic and commercial water softeners use ion exchange resins to remove calcium and magnesium ions. In terms of control, the working steps of the water softener are controlled...

AI Technical Summary

Problems solved by technology

[0005] Existing on-line testing equipment such as hardness testing is bulky, expensive, and inconvenient to install and maintain, resulting in limited application in household or commercial water softeners

The system is mainly set according to the initial water quality, lacks immediate response to water quality changes, and fails to make corresponding intelligent adjustments to the softening process, regeneration process, backwashing and forward washing processes in real time according to changes in water quality, such as softening time, The amount of softened water, regeneration time, regenerated water amount, flushing time, flushing water amount, backwashing time, and backwashing water amount, etc., lead to the following consequences: the hardness value of the produced water exceeds the standard, the regeneration time is too short and the resin performance is not restored, and the regeneration time is too long resulting in Waste of salt and water, incomplete backwashing or excessive backwashing lead to waste, etc.
