Water purifier provided with total dissolved solid (TDS) monitoring device, and its water quality monitoring method

Abstract

The invention relates to the water treatment industry, and concretely relates to the deep filtering of drinking water. The invention discloses a water purifier provided with a TDS monitoring device, and its water quality monitoring method. The water purifier comprises filter galls having different filter materials, and a water flow pipeline, wherein all the filter galls are connected in the water flow pipeline in series to form a filter channel; the filter gall having a smallest filter material screen net aperture is a fine filter gall, and comprises the TDS monitoring device provided with an over-limit alarm; the monitoring probe connected with the input end of the monitoring device is positioned in the water outlet pipeline of the fine filter gall; and the output end of the TDS monitoring device is connected with the over-limit alarm. The TDS monitoring device continuously monitors the residual TDS in flow water through the monitoring probes arranged in the water outlet pipelines of the filter galls, and the residual TDS is used as the basis for determining and controlling the gradual change process of the filtering states of the filter galls; and the over-limit alarm alarms to promote a user after the TDS exceeds a preset limit value.

Description

[0001] Title of prior application: Water purifier with total dissolved solids monitoring device and water quality monitoring method thereof [0002] Prior application number: 201110176963.3 technical field [0003] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0004] At present, water purifiers are relatively popular in China. The water purifier is used to deeply filter the impurities in the water and water pipelines, which better protects the health of users. Yet, along with the popularization of water purifier, their defect and deficiency also gradually exposed in application aspect. After the filter element of the water purifier is used for a period of time, the filter material of the filter element is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption ef...

AI Technical Summary

Problems solved by technology

It is neither continuous nor specific to a certain filter gall, and it is even more impossible to continuously monitor the whole process of the gradual change of a certain filter material layer, so it cannot provide a control basis for the microscopic gradual change process of processing impurities retained by the filter gall, and lacks operability

In addition, the application effect of water purifiers in areas with high hardness water quality has not been good: the effect of microfiltration grade filter gallbladder in reducing hardness is poor; the mode of reducing tap water hardness by chemical methods has potential risks; The gallbladder is easy to be blocked and has a short lifespan. Users do not know which filter to dispose of and can only rely on professional service personnel

Above-mentioned defective and deficiency have had a strong impact on the popularization of water purifier product and the raising of quality
