Please refer to Fig. 1-Fig. 9.A kind of water purifier is provided in the application embodiment, comprising: filter mechanism 5；The filtering Mechanism 5 has original water inlet, filtering water outlet and wastewater outlet；The flushing machine that can be connected with the original water inlet；Institute The filter mechanism 5 can be rinsed by stating flushing machine；The recovering mechanism that can be connected with the wastewater outlet；The recovering mechanism The water that the wastewater outlet is discharged when the filter mechanism 5 is rinsed in storage can be recycled.

A kind of control method of water purifier is also provided in the application embodiment.Wherein, the water purifier has filter Structure 5, the filter mechanism 5 have original water inlet, filtering water outlet and wastewater outlet.The control method packet of the water purifier It includes step: rinsing the filter mechanism 5 of the water purifier；And the wastewater outlet when filter mechanism 5 is rinsed in recycling storage The water being discharged.

In the application embodiment, the flushing machine can use raw water and/or cross drainage washing filter structure 5. Wherein, for the water purifier when being in normal boot-strap water state, the filter mechanism 5 of water purifier can flow into water by original water inlet (water can be the raw water that upstream is transmitted, such as tap water, or the raw water after prefilter component filters；Also Can be other water, such as the water that is recycled of recovering mechanism), and the water is filtered to form drainage, drainage is crossed then from mistake Filtered water outlet discharge, correspondingly, the waste water (or concentrated water) that filter mechanism 5 generates then is flowed out from wastewater outlet.Wherein, from raw water into For mouth to wastewater outlet, the TDS concentration of water is increasing.

In water purifier not water processed, to avoid the waste water side of filter membrane (also referred to as diaphragm) of filter mechanism 5 from (going out with waste water Mouthful communicate side) concentrated water in ion penetrate through filter membrane and entered drainage side, and cause after booting to cross drainage TDS dense Raising problem is spent, water purifier enters cleaning model.Rinse water (raw water and/or excessively drainage) was input to by flushing machine operation The original water inlet of filter structure 5 is rinsed filter mechanism 5 by raw water and/or mistake drainage.At this point, drainage was not discharged in water purifier, But it is not intended to limit whether filtering water outlet is discharged.

Wherein, the raw water and/or mistake drainage that flushing machine introduces flow directly into wastewater outlet from original water inlet, to push 5 original water inlet of filter mechanism is originally remained in the higher water of concentration (waste water) of wastewater outlet (waste water side) and by it from filtering It is discharged inside mechanism 5, so that remaining in (filter membrane) the waste water side of filter mechanism 5 as raw water and/or crossing drainage.

As in this case, waste water side and cross drainage side be drainage or for raw water, cross drainage, water at waste water side TDS is smaller, thus in the process of water not processed or stopping process waste water side water on cross drainage side cross drainage TDS influence compared with It is small, and then guarantee that TDS will not be higher in the drainage excessively produced when water purifier is just switched on water processed, promotes drinking water quality.

Meanwhile the water purifier in present embodiment is additionally provided with recovering mechanism, recovering mechanism will flow out the flushing of wastewater outlet Waste water is recycled, and flushing waste water after the recovery can rinse and produce drainage, and the partial flushing waste water is avoided to be discharged waste, So as to promote water purifier water effect.

Please continue to refer to Fig. 1-Fig. 9.The water that recovering mechanism is discharged when can be by washing and filtering mechanism 5 recycles storage, to mention Rise water purifier water effect.When washing and filtering mechanism 5, the water that the wastewater outlet of filter mechanism 5 is exported is properly termed as flushing waste water, with With filter mechanism 5 normally water processed when the waste water that is formed mutually distinguish.In this embodiment, the filter mechanism is rinsed in recycling storage The water that the wastewater outlet is discharged when 5, namely are as follows: the flushing waste water that the filter mechanism 5 is discharged is rinsed in recycling storage.

When flushing waste water being recycled storage while water purifier passes through recovering mechanism in washing and filtering mechanism 5, the recycling Whole (flushing) water that mechanism filter mechanism 5 can be discharged, which flows back, to be stored, and partial flushing return of waste water can also be stored, this When partial flushing waste water can be discharged from waste outflow pipe 200.Preferably, recovering mechanism can be by whole flushing waste waters Recycling, so that washing and filtering mechanism 5 does not influence water purifier water effect.

Schematic quality is exemplified as, which can form the closed loop water route of circulation with filter mechanism 5 when rinsing (can connect other assemblies on the water route, such as the water booster pump 4 for driving water route to run), at this time gives up whole flushings Water recycling storage.In addition, the recovering mechanism and filter mechanism 5, waste outflow pipe 200 (have multifunctional electromagnetic valves, combination thereon Solenoid valve has the function of throttling and on-off.Specifically, the multifunctional electromagnetic valves may include electromagnetic switch valve 15 in parallel and give up Water proportioner 8.), at this time by the throttling action of the waste water proportioner 8 on multifunctional electromagnetic valves, thus by Partial filtration mechanism 5 Flushing waste water is recovered mechanism recycling, and partial flushing waste water is discharged outside water purifier by waste outflow pipe 200.

In embodiments, the filter mechanism of the second predetermined time can be rinsed, to pass through control washing time Come washing and filtering mechanism.Specifically, rinsing the filter mechanism 5 of the water purifier can stop down to the second predetermined time, correspondingly, The recycling storage water that the wastewater outlet is discharged when rinsing the filter mechanism 5 also stops immediately.Washing and filtering mechanism 5 can be with The operation for controlling booster pump 4 (or continuity duration of the place state of respective valves switch) is realized.

For the promotion for guaranteeing water effect, in washing and filtering mechanism 5, waste water is not discharged in the water purifier.Specifically, described useless Water out is communicated with waste outflow pipe 200.Waste water waste cock 9 can be equipped on the waste outflow pipe 200.The punching Washing machine structure rinses the waste water waste cock 9 when the filter mechanism 5 and closes.For convenient for automatic control, the waste water waste cock 9 It can be electromagnetic switch valve.

To avoid that drainage was still discharged after water purifier shuts down, when rinsing the filter mechanism 5, the water purifier is not arranged Drainage is crossed out.Correspondingly, the filtering water outlet is connected with filtering water delivery pipe road 300, the end in the filtering water delivery pipe road 300 End is connected to useful water end (W.E.), such as: tap, shower etc..At this point, tap of water purifier etc. is in water end (W.E.) equipment closes shape State.Certainly, at filtering close the water end (W.E.) in water delivery pipe road 300 equipped with (being may include tap or use water power with water valve 7 Magnet valve), in washing and filtering mechanism 5, this is in close state with water valve 7.

As can be seen that drainage was neither discharged in the water purifier, waste water was not also discharged, not shadow in washing and filtering mechanism 5 The whole water effect of (not reducing) water purifier is rung, while can preferably reduce booting TDS again.

In the present embodiment, the concentrated water between original water inlet and wastewater outlet can be replaced with raw water by flushing machine And/or drainage is crossed, the concentrated water that 5 Central Plains of filter mechanism retains is discharged from wastewater outlet, so that the waste water side or raw water side of filter membrane Contact is raw water and/or crosses drainage rather than concentrated water.The water that 5 Central Plains of filter mechanism retains can be straight after wastewater outlet discharge It connects and is expelled to recovering mechanism through default pipeline, thus water processed again after powering.

In the application embodiment, flushing machine can use raw water and be rinsed to filter mechanism 5, so that filter The waste water side of structure 5 is full of raw water.Flushing machine also can use drainage and be rinsed to filter mechanism 5, so that filter mechanism 5 Waste water side be full of drainage.In addition, flushing machine also can use raw water and cross the mixing water of drainage to the progress of filter mechanism 5 It rinses, so that the waste water side of filter mechanism 5 is full of mixing water.In view of crossing the TDS in drainage for raw water, mixing water Content is minimum, waste water side can be made to be full of drainage, and then the waste water of filter mechanism 5 by crossing drainage washing filter structure 5 Side and drainage side excessively were drainage, and the water quality that water side is filtered during water purifier is shut down hardly happens change, so as to Guaranteed the water quality of drainage side to greatest extent.

In a preferable embodiment, flushing machine can utilize drainage to be rinsed filter mechanism 5.Wherein, Drainage is crossed used in flushing machine can cross drainage (being referred to as pure water) for what the filter mechanism 5 filtering was formed, It can be formed by other filter assemblies (such as nanofiltration membrane component, ultrafiltration membrane elements, micro-filtration membrane element ion membrane component etc.) Cross drainage.

In view of in washing and filtering mechanism 5, the operation of booster pump 4 is formed by hydraulic pressure can be in the filtering of filter mechanism 5 Water side forms a certain amount of drainage excessively.To utilize the Partial filtration water, promotion water purifier water is imitated, when rinsing the filter mechanism 5, The drainage of crossing of the filtering water outlet discharge rinses the filter mechanism 5 together with the flushed drainage.

Preferably, to be identical with the water quality of drainage side two sides is crossed convenient for 5 waste water side of filter mechanism, the flushing machine is to utilize The drainage of crossing of the generation of filter mechanism 5 rinses filter mechanism 5 for preferred scheme.For the filtering water phase area used with user Point, the drainage of crossing for washing and filtering mechanism 5 is properly termed as " flushed drainage ".Correspondingly, following first receiving spaces 12 are used In the flushed drainage of receiving.

Specifically, the flushing machine may include the first receiving space 12 for crossing drainage for storing (flushing).It is described It supplies water when first receiving space 12 is different to the original water inlet and inputs water from the filtering water outlet.Wherein, the mistake Filtered water outlet can be communicated with the filtering water delivery pipe road 300 being connected with water end (W.E.).The first receiving space 12 with it is described Filtering water delivery pipe road 300 is connected.

In this embodiment, the first receiving space 12 of flushing machine is communicated with filtering water outlet, can so be passed through What filter structure 5 was produced crosses drainage and inputted drainage into first receiving space 12.Wherein, water purifier can be to user's water end (W.E.) While exporting drainage, the moisturizing into first receiving space 12.At this point, the filtering that filter mechanism 5 is exported by filtering water outlet Water section transfers to user's water end (W.E.), partially transfers to first receiving space 12.

In addition, for the water consumption for avoiding influencing user's water end (W.E.), water purifier be can have individually to first receiving space The Water supplement pattern (or moisturizing time) of drainage was inputted in 12.Under the Water supplement pattern, filtering that filter mechanism 5 will be produced normally Water is fully entered to first receiving space 12.The Water supplement pattern can stop being run with after water in user, not interfere user Normal use.

When needing washing and filtering mechanism 5, first receiving space 12 is connected with the original water inlet of filter mechanism 5, and will Its flushed drainage stored is input in filter mechanism 5 through original water inlet.It is carried out after water processed in view of rinsing, described the It supplies water when one accommodation space 12 is different to the original water inlet of the filter mechanism 5 and inputs water from filtering water outlet.

For the flushing waste water that effective use recovering mechanism is recycled, the water of washing and filtering mechanism 5 is recycled completely, is kept away The waste of flushing-free waste water, so as to effectively promote water purifier water effect.The recovering mechanism can also be with the original water inlet phase Connection.Wherein, it supplies water to the original water inlet and when the recovering mechanism difference from the wastewater outlet recycle-water.

Wherein, when recovering mechanism is connected with original water inlet, filter mechanism 5 may be at producing filtering water state, the mistake Drainage can be used for user's use, namely be exported by water purifier.In addition, this, which crosses drainage, can be used for washing and filtering mechanism 5, Flushed drainage is formed by water purifier itself storage, to reduce the TDS of booting water outlet.

In preferred embodiment, the water of recycling storage is input in the filter mechanism 5 and produces washing and filtering by water purifier Water；Also, the filter mechanism 5 of the water purifier is rinsed using the flushed drainage, to not influence water purifier entirety water effect. In this embodiment, the water of recycling storage is input in the filter mechanism 5 and produces flushed drainage to first pre- by water purifier It fixes time stopping, stopping when can also reaching predetermined amount, for example, the water of recycling storage is to be used up.

In embodiment as shown in Figure 4-Figure 6, it is contemplated that flushed drainage and the flushing water of recycling share same sky Between, to avoid flushed drainage and flushing water or the mutual crossfire of raw water, and influence flushed drainage water quality.System in the embodiment It takes flushed drainage step and 5 step of washing and filtering mechanism that can control by the time, namely produced for the first predetermined time The flushed drainage and, rinse the second predetermined time the filter mechanism.

In the application embodiment, the water of recycling storage can be input in the filter mechanism 5 by the water purifier Produce flushed drainage.The flushing waste water that recovering mechanism is recycled can be re-used, and produce flushed drainage.Producing punching When washing drainage, waste water can be discharged in water purifier, guarantee that flushed drainage has lower TDS.Correspondingly, water purifier is in Jiang Chong Raw water can be inputted while washing waste water input filter mechanism 5, raw water is inputted together with flushing waste water in filter mechanism 5 and is produced Flushed drainage.

In embodiments, to promote water effect, the water of recycling storage is input in the filter mechanism 5 and produces by water purifier When flushed drainage, waste water is not discharged and drainage was not discharged for the water purifier.So influence producing flushed drainage not The water of water purifier is imitated, and the TDS of flushed drainage is lower, meets the requirement for reducing booting TDS.

Specifically, filter mechanism 5 can also be weighed by the waste water that wastewater outlet is discharged while producing flushed drainage Newly filter mechanism 5 is input to be utilized.To realize the discharge of water purifier zero waste water when producing flushed drainage.Water purifier is by institute It states the waste water that flushing waste water and filter mechanism 5 export and is input in the filter mechanism 5 together and produce flushed drainage.

As shown in figs. 1-9.In the particular embodiment, the wastewater outlet can by first pipe 400 with it is described Original water inlet is connected；The first pipe 400 is equipped with the first valve member 10 (Fig. 1-Fig. 3 is known as return valve).Wherein, institute It states first pipe 400 and is producing being input to the waste water that the wastewater outlet flows out when crossing drainage of the first receiving space 12 The original water inlet.

In this embodiment, first valve member 10 normally water processed when closing, shut down (user stops with water) make afterwards It takes and is opened when flushed drainage and washing and filtering mechanism 5 to promote water effect.First valve member 10 can be electromagnetic switch Valve, or electromagnetic switch valve is connected in series with check valve combines formation, wherein can prevent liquid from returning by the check valve Stream.

In addition, the first valve member 10 also can have throttling function, is flowed back with control and rinse speed, make flushing effect more It is good.Specifically, the first valve member also may include concatenated throttle valve, electromagnetic switch valve.It is flowed back and is rushed by throttle valve control Speed is washed, the on-off of first pipe 400 is realized by electromagnetic switch valve, and then realizes control washing and filtering mechanism or produces flushing Cross the progress of drainage.

In the present embodiment, first pipe 400 can be individual pipeline, can also with a variety of pipeline common conduits, or Person combines to be formed by the section of tubing of a variety of pipelines, the application and with no restriction.Correspondingly, other pipelines in the application, It equally can be individual pipeline, it can also be with a variety of pipeline common conduits, or the section of tubing combination for passing through a variety of pipelines It is formed, the application and with no restriction.

To save cost, while not influencing using effect.As a preferred option, the waste outflow pipe 200 and institute State 400 common sparing pipeline of first pipe.In such as Fig. 4-embodiment shown in Fig. 9, it can be equipped on the common sparing pipeline Waste water proportioner 8 (is referred to as waste water ratio).That is, waste water proportioner 8 is set to the common sparing of waste outflow pipe 200 Pipeline.Waste water of the filter mechanism 5 during water processed is controlled by waste water proportioner 8, ratio is discharged, to guarantee water purifier water Effect, normally produced drainage.First valve member 10 is set to the downstream of the common sparing pipeline of first pipe 400, that is, First valve member 10 is located at the not common sparing of first pipe 400.

In addition, as shown in Figure 1-Figure 3, the non-common part of the waste outflow pipe is equipped with waste water proportioner 8.This When, speed is rinsed for control, the first valve member 10 can have throttling action, and description of continuing from the preceding paragraph, the first valve member can To include concatenated throttle valve, electromagnetic switch valve 15.Waste water proportioner can be parallel with electromagnetic switch valve 15, form combination electromagnetism Valve.

In this embodiment, the electromagnetic switch valve 15 in parallel of waste water proportioner 8 is it is possible to prevente effectively from recovering mechanism returns The flushing waste water of receipts causes TDS excessively high because recycling.In one embodiment, which can be by recycling storage Water is discharged from the water purifier.Wherein, the flushing waste water which can be stored recovering mechanism after the predetermined time from Water purifier discharge, for example, every 10 days discharge once flushing waste water.Alternatively, will recycling when the TDS of flushing waste water reaches predetermined value The flushing waste water that mechanism is stored is discharged from water purifier.Specifically, in the flushing water discharge that will be recycled, by the electromagnetic switch valve 15 open, and closing the first valve member 10, the water of recycling storage can be discharged from water purifier.

It can be seen that in the present embodiment, it will after the certain number of water purifier washing and filtering mechanism 5 or preset time Once flushing waste water is discharged, the waste water to avoid excessive concentrations influences the service life of film or reduces the effect of TDS.

As shown in figs. 1-9.Waste water waste cock 9 can also be in series on waste outflow pipe 200.It is flushed producing When drainage, recycling flushing waste water, washing and filtering mechanism 5, waste outflow pipe 200 is closed.In the normal water (user processed of water purifier With water) when, the waste water waste cock 9 of waste outflow pipe 200 is opened, and water purifier is discharged in waste water.
