Description
Technical field
The present invention relates to water purification machines, more particularly to the water-saving water purification system of reverse osmosis water purification machine.
Background technique
Due to the anxiety of water resource, the whole world is all water-saving in propulsion energy-saving, therefore water resource is recycled, to water-saving
To very big effect.Wherein tap water can be divided into pure water and condensed water during manufacturing pure water by reverse osmosis water purification machine,
The water purification system of reverse osmosis water purification machine be all by condensed water direct emission, to cause the waste of water resource, and condensed water
It is the water filtered by front filter element unit, still can brings as slurry, therefore it will cause a large amount of for direct emission
Water resource waste.
Summary of the invention
The purpose of the invention is to overcome prior art there are the shortcomings that, provide and return condensed water during a kind of water processed
It receives and utilizes, improve the utilization rate of condensed water, reduce the water-saving water purification system of the reverse osmosis water purification machine of water resource waste.
The technical solution of the water-saving water purification system of reverse osmosis water purification machine of the present invention is: it is characterized by comprising water inlet, into
The mouth of a river connects front filter element, and front filter element connects the first solenoid valve, and the first solenoid valve connects water pump, and water pump connects reverse osmosis membrane,
It is divided into pure water mouth after reverse osmosis membrane filtration and the mouth of a river is concentrated, pure water mouth connection check valve, check valve the first tee tube of connection, first
Tee tube connects pressure pot and postposition filter core, and postposition filter core connects pure water outlet, and the concentration mouth of a river connects the second tee tube,
Second tee tube connection concentration water pipe and drainpipe, concentration water pipe connect life tap, second solenoid valve are arranged on drainpipe
And second throttle, drainpipe connect discharge outlet.
The invention discloses a kind of water-saving water purification system of reverse osmosis water purification machine, it is broadly divided into two working conditions, first
When kind working condition is that user opens life tap, if there is no the pure water of storage pure water or storage less in pressure pot at this time,
Control system receives life tap opening signal, and control system controls the first solenoid valve and water pump is opened, at this time tap water
Enter from the inlet front filter element carry out first filtering, by water pump by first of filtered water be delivered in reverse osmosis membrane into
Filtered pure water is delivered in pressure pot and is stored through check valve and the first tee tube by the filtering of row second, reverse osmosis membrane, and
Second solenoid valve and second throttle at this time is in close state, and filtered condensed water is then through the second tee tube from life water
Condensed water can be used as washing clothing, dishes etc. by faucet discharge, people, and after storing up full pure water in pressure pot, pure water be cannot be introduced into
Pressure pot, water pump and reverse osmosis membrane stop working at this time, and tap water is straight through the first solenoid valve after first of front filter element filtering
It connects from life tap and is discharged；Second of working condition is when user opens pure water outlet using pure water, if in pressure pot
There is pure water, then can first be delivered to the pure water in pressure pot after postposition filter core carries out the filtering of third road just through the first tee tube
Be discharged from pure water outlet, if in pressure pot without pure water after, control system controls the first solenoid valve and water pump and opens, tap water
Front filter element is delivered to through water inlet and carries out first of filtering, then first of filtered water is delivered to reverse osmosis membrane by water pump
Second filtering is carried out, filtered pure water is delivered to postposition filter core through pure water mouth and the first tee tube and carries out the filtering of third road,
Finally it is discharged from pure water outlet, and the concentrated mouth of a river of filtered condensed water, the second tee tube are delivered to drainpipe, arrange at this time
Second solenoid valve and second throttle on water pipe are opened, and condensed water is discharged from discharge outlet.The section of this programme reverse osmosis water purification machine
Water water purification system can be made the condensed water being discharged after filtering by the way that the mouth of a river will be concentrated while connecting discharge outlet and life tap
It makes a living the washing water applied flexibly, the utilization rate of condensed water is improved, to effectively reduce water resource waste.
The water-saving water purification system of reverse osmosis water purification machine of the present invention, connects first between first tee tube and pressure pot
Pressure sensor connects first throttle valve between the concentration mouth of a river and the second tee tube, and second pressure is arranged on concentration water pipe
Sensor.By the way that the first, second pressure sensor is arranged, hydraulic pressure is incuded by pressure sensor, realizes control system control electricity
Magnet valve and water pump open or close, when the hydraulic pressure in pressure pot is reduced to the setting low pressure limit of first pressure sensor,
Prove that pure water is insufficient in pressure pot, when hydraulic pressure is increased to the setting upper pressure limit of first pressure sensor, it was demonstrated that storage in pressure pot
Full pure water；When opening life tap, the pressure decline that second pressure sensor sensing arrives, and when closing life tap,
The pressure rise that second pressure sensor sensing arrives；And first throttle valve is connected between the concentration mouth of a river and the second tee tube, the
One throttle valve can control the flow of life tap and the flow of discharge outlet.Connect between first tee tube and pressure pot
First flow sensor is connect, second flow sensor is connected between the first tee tube and postposition filter core, at the concentration mouth of a river and the
First throttle valve is connected between two tee tubes, third flow sensor is set on concentration water pipe.Pass through first flow sensor
Come that induction pressure bucket flows into and the flow of discharge pure water learns the surplus of pure water in pressure pot；When in pressure pot without pure water
Afterwards, the pure water after reverse osmosis membrane filtration is fed directly to postposition filter core, can incude pure water by second flow sensor at this time
Flow, pure water flow be reduced to setting lower limit after, it was demonstrated that be turned off pure water outlet；It can be felt by third flow sensor
Should life tap open or close；And first throttle valve is connected between the concentration mouth of a river and the second tee tube, first throttle
