Water purifier, water purification system comprising same, and control method

Abstract

The invention provides a water purifier, a water purification system comprising the same, and a control method. An ultrafiltration membrane assembly and a nanofiltration membrane assembly are sequentially arranged from a raw water inlet port to a water supply port, an inlet water flow detector and an inlet water TDS detector are arranged between the raw water inlet port and the ultrafiltration membrane assembly, a direct drinking water flow detector and a direct drinking water TDS detector are arranged between the nanofiltration membrane assembly and the water supply port, and a direct drinking water tank is arranged between the direct drinking water TDS detector and the water supply port. The flow and the water quality of each of inlet water and direct drinking water are detected in realtime through the inlet water flow detector, the inlet water TDS detector, the direct drinking water flow detector and the direct drinking water TDS detector, the opening angle of a concentrated waterelectric control valve is controlled and adjusted according to different raw water qualities to adjust the raw water recovery rate, and the completed water inlet amount is monitored in real time to judge whether a filter element reaches a replacement state or not, so that the workload of field maintenance is greatly reduced, and the labor cost of operation is saved.

Description

technical field [0001] The invention belongs to the technical field of water purification equipment, and in particular relates to a water purifier, a water purification system containing the same and a control method. Background technique [0002] With the improvement of people's living standards and the enhancement of awareness of environmental protection and self-care, people no longer stop at the level of thirst quenching for drinking water, but put forward higher requirements for the quality of drinking water. Based on the needs of the majority of users, the use of water purifiers is becoming more and more widespread. Water purifiers are water treatment equipment that perform deep filtration and purification of water quality according to the requirements for water use. Commercial water purifiers are water purifiers used in public places, and are widely used in schools, office buildings, companies, units, etc. In order to further improve the convenience of using the wate...

AI Technical Summary

Problems solved by technology

However, for this water purifier, the water quality can only be detected by the TDS value of the influent and produced water, and it is impossible to further intelligently adjust the operating parameters of the equipment based on the content of this parameter, such as the recovery rate of raw water, to further ensure the efficiency of the water purifier; at the same time The pure water machine uses RO membrane filtration, and the filtered water cannot be hygienic for long-term drinking; it uses pressure barrels to store water, the water storage capacity is small, the water supply pressure is unstable, there are hidden dangers of secondary pollution, and circulation cannot be realized
