Method for automatically draining pure water machine RO membrane membrane-immersed polluted water

Abstract

The invention provides a method for automatically draining pure water machine RO membrane membrane-immersed polluted water. A single chip microcomputer intelligent control system, a pressure control system, a water quality detection system, a water quality purification system, a water flow control system and pipelines are included. The pressure control system, the water quality detection system, the water quality purification system and the water flow control system are connected through the pipelines. The pressure control system, the water quality detection system, the water quality purification system and the water flow control system are connected with the single chip microcomputer intelligent control system. The single chip microcomputer intelligent control system is provided with an LED display interface and a voice alarm reminding device. Membrane-immersed polluted water which does not reach the standard after a short halt is drained from a membrane-immersed water drainage electromagnetic valve through the single chip microcomputer by dynamically detecting a TDS value of tap water, a TDS value of purified water, the accumulated water producing capacity and other data.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a method for automatically discharging polluted water soaked in an RO membrane of a pure water machine. Background technique [0002] The World Health Organization stipulates that the TDS (the sum of solid substances dissolved in water) value for human drinking water should not exceed 50ppm, while China currently stipulates that the TDS value of tap water should not exceed 1000ppm. Therefore, the current tap water in China is not suitable for direct drinking , must be purified by a pure water machine or filter before drinking. As water pollution becomes more and more serious, the quality problems of domestic tap water suppliers have been repeatedly exposed. Pure water machines have begun to be popularized on a large scale and have entered thousands of households. However, the control system of pure water machines has always been relatively backward and cannot truly guarantee the...

Problems solved by technology

Since the general pure water machine is not equipped with a detection device, the user does not know that the water quality is polluted by the RO membrane immersion membrane when using it, especially when the user’s water consumption is small each time, it will cause the user to repeatedly use the contaminated immersion membrane Water cannot guarantee the user's water safety, and the pure water machine also loses its original meaning of water purification
