Description
Technical field
The utility model relates to a kind of large discharge household reverse osmosis water-purifying machine.
Background technology
At present, the use of household reverse osmosis water-purifying machine is more and more general, wherein 99% household machine internal configuration even more than 99% is all the low discharge reverse osmosis membrane of single 50GPD, the water flow when implication of 50GPD is machine water is every day 50 gallons, namely water flow is 130mL/min, when this water flow is fetched water relative to user, acceptable water flow (it has been generally acknowledged that and be not less than 800mL/min) is too little really, in order to address this problem, this water flow is that the low discharge household reverse osmosis water-purifying machine of 50GPD is provided with pressure water storage barrel.Had pressure water storage barrel, the water flow of machine can reach more than 1000mL/min, and this just meets the requirement of water flow when user fetches water.
After pressure water storage barrel is set up, on the one hand, in pressure water storage barrel, bucket internal cavity is divided into water cavity and air cavity by usual flexible diaphragm of rubber, the pressure of about 0.05MPa is provided with in air cavity during product export, after product comes into operation, during water processed, the water outlet of water-purifying machine is pressed into water cavity, along with the increase of moisture storage capacity, pressure in pressure water storage barrel also increases thereupon, hydraulic pressure in water cavity can go out by pressurized gas when user fetches water in air cavity, so, usual diaphragm of rubber is part indispensable in pressure water storage barrel, but, the side of diaphragm of rubber contacts with pure water, the smell of rubber will to stripping in pure water, make water outlet scent of, and rubber surface is easy breed bacteria also.
On the other hand, the water cavity of pressure water storage barrel only arranges a small-sized opening usually, is water outlet, also be water-in, because the too little water cavity inside of opening can not be cleaned effectively, the time is slightly long, will cause the total plate count index exceeding standard of the water in water butt.
In order to eliminate the rubber smell that may exist in water outlet, again post active carbon is set in the outlet pipeline of pressure water storage barrel, but, although gac can eliminate water peculiar smell, improve mouthfeel, be the hotbed of bacterium also, this facilitates again the water outlet total plate count index exceeding standard of water purification machine further.
So in recent years, some enterprises adopt the reverse osmosis membrane of large discharge in family expenses reverse osmosis water purifier, make water flow during machine water be not less than 0.8L/min, cancel pressure water storage barrel, thus fundamentally solve the series of problems that brings of pressure water storage barrel.
Fig. 1 is the pipeline schematic diagram of typical large discharge household reverse osmosis water-purifying machine in known technology, it comprises outlet valve, check valve, high-voltage switch gear, water pump, pretreater, water intaking valve, throttling valve, flush valve, pretreater import water receiving source, the import of pretreater outlet water pump, exit of pump connects the import of reverse-osmosis treated device, the pure water outlet of reverse-osmosis treated device connects check valve and outlet valve successively, throttling valve is all communicated with the dense water out of reverse-osmosis treated device with the import of flush valve, the equal emptying of outlet of throttling valve and flush valve, water intaking valve is arranged between the first step and second stage pretreater.Water-purifying machine is when standby, water intaking valve is closed, can guarantee that throttling valve can not continue flowing water (throttling valve does not have water cut-off function), make the filter element shells at different levels in water intaking valve export pipeline simultaneously, and the housing of reverse-osmosis treated device does not all bear pressure, this is good to water-purifying machine Leakage prevention.But, just because of standby time water intaking valve export pipeline in filter cores at different levels, and the housing of reverse-osmosis treated device does not all bear pressure, namely its inner gas existed can fully be expanded, water in pretreater housing at different levels and reverse-osmosis treated device housing will be extruded to greatest extent and is flowed away from throttling valve after gas expansion, like this, when user fetches water, open outlet valve, hydraulic pressure in pipeline between outlet valve to check valve will decline rapidly, make the high-voltage switch gear take-off in this pipeline, so, starting mode of pump, water intaking valve is opened, flush valve is closed, machine starts water processed.Machine standby time is likely long, water in pretreater housing and reverse-osmosis treated device housing may Yin Qinei gas expansion and discharge more, the pressure of reverse-osmosis treated device enclosure interior Yuan Shui side does not increase for the moment, water flow when causing reverse-osmosis treated device water initial is smaller, this just needs little by little to amount of makeup water in pretreater housing and reverse-osmosis treated device housing, compress the gas in it simultaneously, then, the pressure of reverse-osmosis treated device enclosure interior Yuan Shui side could little by little rise, the water flow finally reaching machine during maximum just can reach designs discharge, time needed for this process, through the impression of verification experimental verification and users, 0 second ~ 60 second time of usual needs, the length of this time depends on the length of standby time.Standby time is longer, and the time needed for this process is longer; If standby time is zero, then water flow reaches at once and designs discharge.But, standby time be zero situation there is no in actual procedure, in most of the cases, standby time is all long, that is, in most cases, the initial water flow of the large discharge household reverse osmosis water-purifying machine of this known technology does not all reach requirement, and the prerun that needs to start shooting just can reach requirement close to time of 1 minute.This generates following problems:
1. to wait for the time of one section of machine not water outlet when user fetches water, experience bad;
2. observable index is larger, the amount of in most cases at every turn fetching water because of household machine is all little, such as, at about 1L, even frequent less than 1 liter, the normal water flow of machine is about 1L/min,, that is, if water flow reaches close to 1L/min after start at once, then the amount of on time machine water outlet in about 1 minute just can meet the requirements, but due in most cases, through 0 ~ 60 second, just will reach close to 1L/min close to 1 minute water flow after being actually often start after machine start.1L water to be got like this from machine, machine will leave the time close to 2 minutes, not water outlet working time or the water flow of the similar half of machine are less, the energy that this part working time consumes only is used to make machine prepare to enter normal operating conditions, not doing the merit being of value to user, is waste;
3. the work-ing life of water pump, valve is short, as long as because machine is in operation, the life-span of water pump and valve is just in shortening, if although water pump and valve are in operation, needed for user but can not therefrom obtain, the extra consumption of Here it is machine, this is just equivalent to the work-ing life shortening machine.

Water-purifying machine is when water processed, water pump 2 starts, outlet valve 5, pressure maintaining valve 4, water-stop valve 8 open water flowing simultaneously, high-voltage switch gear 6 not take-off, pipeline from water source successively through pretreater 1, water pump 2, reverse-osmosis treated device 3 Yuan Shui side, the outlet of first throttle valve 7 to water-stop valve 8 keeps water flowing (referring to that water is in flowing), or keep water flowing through pretreater 1, water pump 2, reverse-osmosis treated device 3 Yuan Shui side, the outlet of water-stop valve 8 to first throttle valve 7 successively from water source, export and keep water flowing from reverse-osmosis treated device 3 pure water side through pressure maintaining valve 4, high-voltage switch gear 6 to outlet valve 5 successively.Water-purifying machine is when standby, water pump 2 does not start, outlet valve 5 simultaneously, pressure maintaining valve 4, water-stop valve 8 is closed and is cut off the water supply, high-voltage switch gear 6 keeps take-off state, from water source successively through pretreater 1, water pump 2, reverse-osmosis treated device 3 Yuan Shui side, (water molecules can be moved in pipeline by the mode of diffusion in the pipeline maintenance water route connection of first throttle valve 7 to water-stop valve import 8, hydraulic pressure namely in this pipeline can be elevated with the lifting of source pressure), or from water source successively through pretreater 1, water pump 2, reverse-osmosis treated device 3 Yuan Shui side, pipeline to water-stop valve 8 import keeps water route to be communicated with, exporting from pressure maintaining valve 4 keeps water route to be communicated with through high-voltage switch gear 6 to outlet valve 5 import.
Large discharge refers to that the pure water water flow of reverse osmosis water purifier is not less than 300GPD, and the reverse-osmosis treated device 3 in the present embodiment comprises a reverse osmosis membrane assembly, and the pure water water flow of this reverse osmosis membrane assembly is not less than 300GPD.
Pressure maintaining valve 4 is the magnetic valves that can control current break-make, or the water in pipeline can be stoped to allow to the flowing of reverse-osmosis treated device direction the check valve that the water of reverse-osmosis treated device inside flows to outlet valve direction.
Water-purifying machine is when water processed, and water source is in on-state, and water pump 2 is opened and run, water-stop valve 8, outlet valve 5 and pressure maintaining valve 4 all open water flowing, are wherein situations of check valve for pressure maintaining valve 4, the water (flow) direction that check valve requires is consistent with the water (flow) direction of water outlet, and namely check valve is in opened condition; For the situation that pressure maintaining valve 4 is magnetic valves, the non-take-off state of the corresponding high-voltage switch gear 6 of its opened condition when low hydraulic pressure; So pure water flows to outlet valve 5 from the outlet of the pure water of reverse-osmosis treated device 3 through pressure maintaining valve 4, and go out outlet valve 5 and flow out, the water cavity of high-voltage switch gear 6 inside is communicated to the inside of this section of outlet pipeline; Because outlet valve 5 is in opened condition, in pure water outlet pipeline, pressure is very low, and high-voltage switch gear 6 can't detect high pressure therefore can not take-off; Meanwhile, dense water flows to water-stop valve 8 and first throttle valve 7 from the dense water out of reverse-osmosis treated device 3, then emptying discharge; Water-purifying machine is in normally water state processed.
After user closes outlet valve 5, the water outlet of pure water outlet pipeline is turned off, and water pump 2 still continues to run, namely reverse-osmosis treated device 3 also can produce pure water, so the hydraulic pressure in pure water outlet pipeline can rise rapidly, after hydraulic pressure rises to set(ting)value, high-voltage switch gear 6 take-off, so switch off the pump 2 and water-stop valve 8, water when pressure maintaining valve 4 is check valve then in pipeline can not flow to reverse-osmosis treated device 3 (this flow direction is contrary with the flow direction that check valve requires) through check valve, when pressure maintaining valve 4 is magnetic valve, system makes the water in pipeline can not flow to reverse-osmosis treated device 3 through magnetic valve by closing this magnetic valve simultaneously, this just can make from the stable water pressure one section of pipeline that pressure maintaining valve 4 is exported between outlet valve 5 import within the specific limits, this pressure can keep high-voltage switch gear 6 to be in take-off state.At this moment, because water-stop valve 8 is in closing condition, this just can ensure that the hydraulic pressure in the pipeline between Yuan Shui side in the suction culvert of reverse-osmosis treated device 3 and reverse-osmosis treated device 3 and dense water out to water-stop valve 8 thereof is not less than source pressure, make the gas that may exist in pretreater 1 inside and reverse-osmosis treated device 3 inside always be in compressed state, namely make pretreater 1 cavity that is inner and reverse-osmosis treated device 3 inside be in full water state.
Through after a period of time, when user again open outlet valve 5 fetch water time, hydraulic pressure in outlet pipeline declines rapidly, cause high-voltage switch gear 6 take-off, so Controlling System starts water pump 2 water processed immediately, when pressure maintaining valve 4 is check valve, then the water outlet of reverse-osmosis treated device 3 can flow to high-voltage switch gear 6 and outlet valve 5 through check valve, and when pressure maintaining valve 4 is magnetic valve, this magnetic valve of unlatching makes the water outlet of reverse-osmosis treated device 3 flow to outlet valve 5 through magnetic valve by system, opens water-stop valve 8 simultaneously and discharges dense water.Because system can make water making pipe road system keep pressure state when standby, so water pump 2 just can by the pressure needed for the boost in pressure of Yuan Shui side in reverse-osmosis treated device 3 to normal operation in very short time after starting, so, to the sensation of user just as direct the pure water stored in system released (in fact do not establish pressure water storage barrel in system, can not pure water be stored), almost there is no the sensation that water outlet is delayed.
The utility model large discharge household reverse osmosis water-purifying machine does not almost have hysteresis phenomenon due to water outlet, and when user takes the tap water of equivalent, its working time significantly shortens than the large discharge household reverse osmosis water-purifying machine of prior art.Because machine runs will consume electric energy, simultaneously the operational process of water pump 2, magnetic valve is also the process shortening its work-ing life, so, can working time be shortened, be exactly can saves energy, the work-ing life of water pump 2, magnetic valve can be extended exactly.
