RO water purifier control system convenient to adjust concentrated water discharge amount

Abstract

The invention relates to a control system for an RO water purifier that is convenient for adjusting the discharge of concentrated water, comprising a single-chip microcomputer and a water pump driving device connected to the single-chip microcomputer, a combined flushing valve control device, a concentrated water discharge valve control device, and a high-voltage switch control signal circuit , Low-voltage switch control signal circuit, timer, indicator light device, key device and digital tube. Each component of the RO water purifier is controlled by a single-chip computer, especially the control of the concentrated water discharge valve. According to the water quality of the local municipal raw water, the start-stop time ratio of the concentrated water discharge valve can be manually adjusted, and the start-stop time can be intuitively displayed by the digital tube. than the numerical value. It is also possible to add a TDS detection device to realize the automatic start and stop of the concentrated water discharge valve. In addition, multiple expansion modules can be connected to the single-chip computer to realize various control methods, such as: Bluetooth module, WIFI wireless module or radio frequency module, and can realize remote control of external terminals such as mobile phones, tablets or remote controllers.

Description

technical field [0001] The invention relates to an RO water purifier, in particular to a control system of the RO water purifier which is convenient for adjusting the discharge of concentrated water. Background technique [0002] The principle of RO water purification is also called the principle of RO reverse osmosis. RO reverse osmosis is a kind of method such as reverse osmosis, which is currently popular in the world, to filter raw water (physical method) and produce water that can be directly consumed by humans without adding any compounds. Pure water machine (also known as terminal water purification equipment). [0003] The principle is: municipal tap water passes through the water inlet and passes through a multi-stage filter element to separate pure water for drinking, and the concentrated water produced by filtration flows into the sewer for discharge after passing through a fixed waste water ratio combined valve. Take the 50G household water purification system a...

Problems solved by technology

Disadvantages: First, it takes up a lot of space, second, it is costly, and third, it is troublesome to install and use; it is suitable for use in all areas

[0009] 5. Intelligent water-saving type: through the detection of raw water TDS, the discharge of concentrated water is adjusted, which is scientific and reasonable, and has a certain water-saving effect. The disadvantage is high cost and high control requirements. It is suitable for use in all areas

[0010] The above-mentioned existing technologies, while solving water resources, all have their own defects, which are not conducive to large-scale promotion
