Wastewater-free reverse osmosis water purifier control method and water purifier

Abstract

The invention discloses a wastewater-free reverse osmosis water purifier control method. A purified water monitoring unit is disposed at a reverse osmosis filter unit water inlet end channel or concentrated water discharge port. The method specifically includes the steps that: when the water purifier is under a purified water making work state, concentrated water returns to a reverse osmosis filter unit water inlet end channel or a pre-filter unit water inlet end channel through a concentrated water backflow channel or to undergo mixing with inflow water for recycling. The technical scheme provided by the invention has the advantage of no wastewater.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to a control method for a non-wastewater reverse osmosis water purifier and the water purifier. Background technique [0002] The water purifier is also called a pure water machine. Its core technology is RO reverse osmosis membrane. The water purifier can effectively filter out rust, sand, colloid, and adsorb residual chlorine, smell, color, pesticides and other chemicals in the water; It can effectively remove bacteria, toxins, heavy metals, etc. in water, and the application of water purification technology in the field of drinking water. [0003] The core filter element of the reverse osmosis water purifier in the prior art requires a large amount of water to wash the reverse osmosis membrane to produce pure water to prevent fouling of the reverse osmosis membrane. Generally, a fixed ratio is used to discharge concentrated water, that is, to produce a cup of pure water, 3 cups of ...

Problems solved by technology

[0003] The core filter element of the reverse osmosis water purifier in the prior art requires a large amount of water to wash the reverse osmosis membrane to produce pure water to prevent fouling of the reverse osmosis membrane. Generally, a fixed ratio is used to discharge concentrated water, that is, to produce a cup of pure water, 3 cups of concentrated water need to be discharged. The water temperature drops in winter and the ratio of pure concentrated water to 1:6 causes a waste of water resources. The above technologies need to be further improved

[0004] At present, there is a kind of pure water machine without waste water discharge on the market that recycles the waste water discharged from the water purifier into a special waste water tank for use. If the waste water in the waste water tank is not used in time, it will flow to the sewer and discharge waste water indirectly, especially when the water temperature is low. The amount of waste water discharged by the water machine is large, and the capacity of the waste water tank is limited. Most of the waste water is directly discharged into the sewer.
