AI Technical Summary

Technical Problem

The amount of water replenishment of the existing water softener is not accurate, resulting in waste of salt or incomplete regeneration of resin, which makes the user experience poor.

Method used

When the water softener switches to the salt tank water replenishment procedure, the water inlet pressure of the salt tank is obtained, and the water inlet duration of the salt tank is selectively adjusted according to the water inlet pressure to accurately control the amount of water replenishment of the salt tank.

Benefits of technology

By adaptively adjusting the water inlet duration, the error between the amount of water replenishment of the salt tank and the amount of brine required for the resin tank is reduced, the amount of brine required for the resin tank is ensured, the cost of salt is saved, and the cost-effectiveness of the water softener is improved.

Abstract

The invention relates to the technical field of water softening devices, particularly provides a control method of a water softener and the water softener, and aims at solving the problem that the water supplementing amount of a salt box of an existing water softener is not accurate. In order to achieve the purpose, the water softener comprises a salt box and a resin tank which are communicated with each other, the control method comprises the steps that when the water softener is switched to a salt box water supplementing program, the water inlet pressure of a salt box is obtained; and selectively adjusting the water inlet duration of the salt box according to the water inlet pressure. Through the arrangement, the water softener can adaptively adjust the water inlet duration according to different water pressures in different regions so as to reduce the error between the amount of water replenished into the salt tank and the amount of salt water required by the resin tank, so that the amount of salt water required by the resin tank is ensured, the salt use cost is saved, and the use cost performance of the water softener is improved.
