Adaptive method for output voltage of water purifier controller

By monitoring the membrane pressure and flow rate of the water purifier, the target output voltage is determined, enabling the controller to adapt to the voltage requirements of water purifiers with different flow rates. This solves the problem of needing to configure multiple specifications of controllers and water pumps for water purifiers with different flow rates, thus reducing costs.

AI Technical Summary

Technical Problem

Water purifiers with different flow rates require separate controllers and water pumps to meet the corresponding flow rates, which leads to an increase in the specifications of controllers and water pumps, and increases the costs of inventory preparation, procurement and management.

Method used

By monitoring the pressure before the filter membrane of the water purifier, the pure water flow rate and wastewater flow rate are obtained. The target output voltage is determined based on the ratio of pure water flow rate to wastewater flow rate, so as to realize the set flow rate and set pure water to wastewater ratio of the water purifier. The needs of multiple water purifiers with different flow rates can be met by using a single type of controller and water pump.

Benefits of technology

This invention enables the controller to adapt to the water purification voltage requirements of water purifiers with different flow rates, reducing the number of controllers and water pumps required for different flow rates and lowering costs.

Abstract

This disclosure relates to an adaptive method for the output voltage of a water purifier controller. In response to a received water purification command, the water purifier initiates its purification process and monitors the pressure before the filter membrane. When the pressure before the membrane is within the normal operating pressure range of the filter membrane, the method acquires the output voltage provided by the target controller to the target water pump under the current pressure, as well as the pure water flow rate and wastewater flow rate of the water purifier at the specified output voltage. Based on the pure water flow rate, wastewater flow rate, and output voltage, the method determines the target output voltage of the target controller. The ratio of pure water flow rate to wastewater flow rate is the pure-to-waste ratio, and the target output voltage is the output voltage of the target controller that simultaneously satisfies the set flow rate and the set pure-to-waste ratio of the water purifier. This method enables the controller to adapt to the purification voltage requirements of water purifiers with different flow rates, reducing the number of controllers and water pumps required for different flow rates and lowering costs.
