Problems solved by technology

[0003] Based on the pure water machine with the same structure, another concentrated water discharge method is that during the entire pure water production process, the control device controls the concentrated water discharge valve to be opened for a period of time at a specified time point to discharge concentrated water and flush the reversed water. The RO reverse osmosis membrane in the permeation filtration unit, obviously in such a control method, the opening and closing of the concentrated water discharge valve is determined based on empirical values, and has nothing to do with the actual situation of raw water and the actual situation of pure water production. Such concentrated water discharge control method is obviously less accurate

Abstract

The invention relates to a water-saving type RO (Reverse Osmosis) membrane water purifier which comprises a pre-filtration unit and an RO filtration unit, wherein a pressurizing unit is at least arranged between the pre-filtration unit and the RO filtration unit, the output end of the RO filtration unit comprises a purified water delivery outlet and a concentrated water delivery outlet, and the concentrated water delivery outlet is connected with a concentrated water discharge outlet by a concentrated water discharge valve. The water-saving type RO membrane water purifier is characterized in that a purified water flow sensor is arranged on the purified water delivery outlet, the water-saving type RO membrane water purifier further comprises a control unit, the signal output of the purified water flow sensor is connected with the control unit, the output of the control unit controls the on and off of the concentrated water discharge valve. By adopting the concentrated discharge control method, the discharge of the concentrated water can be controlled by adopting purified water flow change value and production as control parameters, and compared with the prior art, the high production efficiency of purified water and the lower discharge amount of the concentrated water can be ensured.

Description

technical field [0001] The invention relates to a water-saving RO membrane reverse osmosis pure water machine and a concentrated water discharge control method thereof, which belong to the RO membrane reverse osmosis filter pure water machine and the concentrated water discharge control method of the RO membrane reverse osmosis filter pure water machine. Background technique [0002] The pure water machine is a kind of water purification equipment that uses multi-stage filter elements for water purification treatment. The function of the pure water machine is to remove floating objects, heavy metals, bacteria, viruses, etc. in the water through filtration. It has a higher filtration technology. , with the improvement of people's living standards, pure water machines have begun to enter people's families in large numbers, and have become household or indispensable supplies. In the prior art, pure water machines generally use multi-stage filtration, mainly including a pre-filt...
