Description
Technical field
The present invention relates to a kind of method of wash toilet device flushing mechanism and a kind of work of closet, more particularly, to saving toilet.
Background technology
The excessive water capacity easily causes that urban water resource is deficient, increases urban sewage pipe loadings, municipal sewage treatment Capability Requirement is improved.Because usage frequency is high, it accounts for urban water consumption greatly with water to closet.
At present, traditional water-washing water closet is respectively provided with sealing structure for water, to reach every smelly and insect protected purpose.But for user, it is with dirt, the hydrops forming water seal to be polluted first when going to toilet, after the completion of excretion, then with substantial amounts of water, contaminated water and dirt are discharged closet.
When stool, dirt solid content is more, needs to consider that dirt discharges closet, simultaneously for avoiding line clogging, dirt needs to go out a certain distance.Current design uses larger drainage pipeline, has substantial amounts of water to flow out closet it is ensured that dirt goes out a certain distance in moment.
When urine, dirt is liquid, and closet only needs to for liquid insults to discharge closet.
Carry out dirt discharge currently for different Excreta differentiation, toilet seat is divided into favourable opposition and two grades of little punching, the difficulty or ease gone out according to dirt, controlling different makes dirt discharge dirt by same blow-off line with water volume.
Hydrops for water seal utilize aspect, patent is had to propose to reuse the hydrops in toilet using interim water tank, but simply this part water is sprayed at a high speed with pump when defecation is rinsed, for strengthening the effect rinsed, when not consider ejection be urine, unnecessary use identical pipeline carries out the discharge of defecation, and urine rinses the booster action also without pump.
According to above technical background, the water saving for closet real qualitative leap at present.
Content of the invention
Based on solve the problems, such as closet economize on water, the present invention provides a kind of flushing mechanism and purging method, before user excretion, the transfer preservation of pelvic part at least a portion hydrops is avoided polluting, urine dirt being discharged using the second drain outlet of differentiation, then using the hydrops preserving backflow again as a part for pelvic part hydrops.
The wash toilet device structure of the application possesses：Pelvic part, has the continuing surface for catching dirt temporarily；Washing water supply mouth, supplies washing water to described pelvic part；First drain outlet, is connected to the lower section of described pelvic part, when toilet seat is for non-usage and pelvic part is collectively forming hydrops portion, forms water seal by the hydrops in this hydrops portion；It is characterized in that being also equipped with：The second drain outlet that pelvic part dirt can be discharged；And hydrops utilize mechanism, at least a portion of described hydrops being introduced, storing, discharge；Described hydrops are had using mechanism：Returnable, by the hydrops storage of described introducing；Diversion unit, at least a portion of described hydrops is introduced described returnable as introducing water；Backwater unit, the diversion of storage in described returnable is returned described pelvic part or described drain outlet.
The wash toilet utensil of the application design has pelvic part, for accepting to dirt, have and supply interface for the washing water connecting water source, washing water supply interface connects with pelvic part such that it is able to washing water is flowed into pelvic part, after dirt falls into pelvic part, dirt can be from the wall landing of basin to the entrance of the first blowdown passage tube being connected to pelvic part bottom.
In non-working condition, first blowdown passage tube and pelvic part can be collectively forming the structure of one or more hydrops, the a part of hydrops of wherein at least functionally can block to blow-off line, plays the effect of water shutoff, thus isolation is from the foul smell building blow-off line and the small worm being likely to occur.
First blowdown passage tube and the second drain outlet are compared, and the former is thicker, and its eigenvalue is diameter about 50mm, and pelvic part functionally together form first wash dirt passage.
Second blowdown passage tube connects with the lower section of hydrops, equally for insect protected with every smelly consideration, closet is in non-working condition, second blowdown passage tube and pelvic part can be collectively forming the structure of one or more hydrops, the a part of hydrops of wherein at least functionally can block to blow-off line, plays the effect of water shutoff.
Hydrops utilize mechanism for the hydrops forming water shutoff during non-working condition, closet can be introduced returnable, preserve temporarily, the water in returnable also can be made to be back to basin body or drain outlet pipeline in returnable.Wherein a part for hydrops is even fully incorporated returnable by diversion unit, and the water introducing in returnable is returned pelvic part or drain outlet pipeline by backwater unit.
So when user carries out before blowdown, at least a portion hydrops can be protected, it is to avoid dirt causes the pollution of hydrops, need when recycled.
Preferably, diversion unit has a pump unit driving pelvic part hydrops to flow to returnable.
In most cases, in order to avoid possible deposit in returnable, lowest surfaces in returnable are needed to be not less than the lowest surfaces of pelvic part.Now using pump, at least a portion hydrops of pelvic part are transferred to returnable, thus avoiding hydrops to be contaminated.

The visible second drain outlet descending branch 33 of Fig. 5 is connected near closet sewage draining exit 124 by the second drain outlet sewage draining exit 19, and lower outlet part 15 outlet shapes are approximately circular.
Fig. 6 is the explanation to returnable 25, returnable priming hole 252 is connected with diversion unit water outlet pipe fitting 24, diversion is introduced inside container, returnable backwater hole 251 is connected with Return water hoses 26, then connects back to water unit import 18 in conjunction with the visible Return water hoses of Fig. 4 26 and diversion can be back to closet pelvic part.In some schemes, in order to avoid the water level in returnable 25 rises too high, there is water level sensor 253, after water level sensor 253 is triggered, by central processing unit, diversion water pump 23 can cut out.
Fig. 7 have expressed diversion unit intake 17 and the second blowdown channel entrance 16 is located at the bottom of pelvic part or perhaps the first drain outlet, and is respectively provided with the second drain outlet foreign body prevention unit 21b and diversion portion foreign body prevention unit 21a.Figure 10 is illustrated to the details of 21b, and the second drain outlet foreign body prevention unit 21b has multiple apertures, prevents larger impurity from entering the second drain outlet.Figure 11 is illustrated to the details of diversion portion foreign body prevention unit 21a, and diversion portion foreign body prevention unit 21a has multiple apertures, prevents larger impurity from entering returnable 25.
Fig. 8 have expressed and have expressed the second drain outlet foreign body prevention unit 21b positioned at the second blowdown channel entrance 16 front end, the second drain outlet sewage draining exit 19, lower outlet part 15 location closet from another direction.
Fig. 9 is the sectional view in non-usage for the closet, also embodies the internal structure that the first drain outlet is cut open.
First drain outlet 12 is relatively thick, similar with blow-off line in the market, and its characteristic diameter is 50mm, can be defecated or urine discharge.The first drain outlet 12 optimizing has ascent stage 121, descending branch 122, the first blowdown channel stagnant water portion 123, closet sewage draining exit 124, and the wherein first blowdown channel stagnant water portion 123 makes closet be respectively provided with water shutoff in use or non-working condition.When pelvic part hydrops be introduced into returnable cause pelvic part water shutoff disappear when, the seal water structure that the first drain outlet 12 is internally formed still can be carried out every smelly and insect protected.But it should be recognized that the first blowdown channel stagnant water portion 123 to the present embodiment for be only optimize it is not necessary to.
Above the first chamber pot flushing water structure is illustrated, its method of work illustrates below, first each point of function is illustrated.
When hydrops utilize mechanism to work, comprise the pump unit energising operating of diversion water pump 23, the filtration through diversion portion foreign body prevention unit 21a for the hydrops in basin body, sequentially pass through diversion unit irrigating gate 17, diversion unit inlet pipe casting 22, diversion water pump 23, diversion unit water outlet pipe fitting 24, returnable priming hole 252 flow into returnable 25 at short notice, when having water in returnable 25, hydrops sequentially enter pelvic part 11 from returnable backwater hole 251, Return water hoses 26, backwater unit water inlet 18, washing water upper water-out portion 14 under gravity.Because returnable backwater hole 251 aperture is less, after diversion water pump 23 stops, the hydrops in returnable 25 flowed slowly in pelvic part 11 within a period of time.Moistening before the water that washing water upper water-out portion 14 flows out can be drained to pelvic part, reduce the probability that dirt is attached to pelvic part, also pelvic part can be carried out, reduce the residual in pelvic part for the urine stain.After the certain time that returnable 25 is introduced into water, the hydrops being introduced into come back to pelvic part 11.
When second drain outlet carries out blowdown, dredge pump 32 makes impeller high-speed rotation lead to local to produce vacuum suction liquid insults and flow through under the driving of electric power, liquid insults are first filtered by the second drain outlet foreign body prevention unit 21b, sequentially through the second blowdown channel entrance 16, ascent stage 31, dredge pump 32, descending branch 33, the second drain outlet sewage draining exit 19, the first drain outlet sewage draining exit 124 flow direction building blow-off line.
Method using the first drain outlet blowdown is identical with current existing on the market toilet seat, is described as follows：Supply substantial amounts of water from washing water supply interface 13 short time and flow to pelvic part 11 through upper water-out portion 14 and lower outlet part 15, produce siphon, make dirt discharge pelvic part 11.Although not producing siphon for non-siphonic formula toilet, but still can reach the purpose of flushing according to its prior art.
Illustrate referring to Figure 12 method of work corresponding to the toilet stool washing structure of the application.In the method for work of the application closet, stool is discharged and carries out dirt discharge by the first drain outlet, and urine is discharged and carried out dirt discharge by the second drain outlet, carries out defecation discharge in the second blowdown channel blockage using the first drain outlet.Preferably when the second blowdown channel blockage, can be with two grades of flushings of size of the prior art by the drain valve structure of control water tank water yield；
When closet is for non-working condition, such as Fig. 9, water seal height in pelvic part 11 is as illustrated, anhydrous in returnable 25.
With reference to Figure 12, in step S01, closet passes through microwave, infrared or allow user trigger switch perceive human body proximity, and the central processing unit of closet can drive corresponding function according to the flowchart program of Figure 12.
Timer T in the control structure of execution step S02 closet after step S01 starts timing, and timing result is using the analysis foundation as following tripartite's surface analysis：From the degree that returnable 25 flows to the water yield of pelvic part 11, pelvic part 11 is cleaned by before rinsing, confirm that user carries out urine.
Then execution step S03, starting diversion water pump 23 makes the hydrops in pelvic part 11 complete diversion action toward returnable 25 movement, returnable 25 water level rises simultaneously, and has water to continue to flow to pelvic part 11 from returnable 25, until diversion is completely exhausted out in returnable 25.
Then execution step 804, judge user whether by button press little rush button, if pressed, carrying out S05, otherwise carrying out step S13.
In step S05, carry out urine flushing according to customer instruction, the discharge of the liquid insults carrying out comprising urine using the second drain outlet.
With reference to Figure 15, central processing unit control of sewage disposal water pump 32 operates, it is partially formed that liquid insults are passed sequentially through the second blowdown channel entrance 16 by negative pressure, ascent stage 31, dredge pump 32, descending branch 33, the second drain outlet sewage draining exit 19, the first drain outlet sewage draining exit 124 flow out closet.Optimize, also allow for dredge pump 32 only short-term operation certain time, after air in the second drain outlet reduces so that forming siphonage, stop the operating of dredge pump 32a, because import the second blowdown channel entrance 16 and outlet 19a have difference in height, siphon will continue to water level in pelvic part 11 be less than 16 when, now complete the discharge of liquid insults.Again during this, at the first blowdown channel stagnant water portion 123, hydrops still keep it to flow in the hydrops in the effect of smelly insect protected, returnable 25 continue to pelvic part 11, help form the hydrops of water shutoff.
In step S06 of step S05 that continues, obtain value t1 of timer T, t1 will be used for calculating whether the urine stain from the water yield and estimation pelvic part 11 basin body that returnable 25 flows to pelvic part 11 before flushing is cleaned completely.
In step step S07 of step S06 that continues, whether judge t1 less than the time T1 setting, T1 is the water marginal value of urinating stain position completely cleaning all to basin body flowing to pelvic part 11 from returnable 25.If t1 is less than the time T1 setting and illustrates that the urine stain of pelvic part 11 is not cleaned by enough water, then be carried out step S08, otherwise execute S12.
In step 808, because the urine stain on pelvic part 11 is not cleaned by completely, but a small amount of number of times has no effect on use, is selected based on deferring to the button in step S04 for the user, so recording basin body with B to urinate the number of times that stain is not continuously rinsed, it is that subsequent step makees reference.
In step s 12, because the urine stain of residual before pelvic part 11 is cleaned completely by the hydrops flowing to pelvic part 11 from returnable 25, so record basin body urinates the B zero that stain is not continuously rinsed number of times.
In step S09 of step S08 that continues or S12, due in the case that Return water hoses 26 and downstream line are certain, the hydrops flowing out from returnable 25 before the second drain outlet completes blowdown can be calculated according to time t1, then calculate using water yield V1 for forming hydrops also needing to outside remaining water in returnable 25 from washing water supply interface 13 offer.
In step S10 of step S09 that continues, washing water supplies interface 13 and supplements, to closet, water yield V1 that S09 calculates, and washing water is arranged to pelvic part 11 through at least one of upper water-out portion 14 or lower outlet part 15, so that the hydrops in pelvic part 11 is highly increased.Simultaneously the diversion in returnable 25 also continues to flow to pelvic part 11 through upper water-out portion 14, As time goes on, until the water in returnable 25 all flows out.In this step, by the backwater in returnable with the washing water of V1 volume that newly increases, the common guarantee height of the hydrops of pelvic part.
The step S11 Counter T of step S10 that continues stops timing, t1 and t2 is zeroed, and closet logic control recovers to original state.
In step S20 of step S11 that continues, toilet stool washing controls and terminates, and closet enters holding state.
If user does not press urine flush knob in step S04, then in step S13 then, microwave or the switch of triggering is relied on to judge whether user leaves, if left, execution step S14, otherwise execution step S17.
In step S14, obtain time t2, this time embodies and is close to, from user, the time that user leaves.
In step S15 then, judge to reflect that user is close to the time t2 leaving and whether is less than setting value T2, shortest time or the maximum duration of urine that T2 defecates for common people.When t1 is less than this setting value it is believed that user has carried out urine, then first carry out step S16.Otherwise auto-flushing is carried out according to stool flushing, execution step S18.
In step s 16, central processing unit confirms that basin body urine stain is not continuously rinsed whether number of times is accumulated to certain number of times, i.e. whether value b1 of enumerator B is less than setting value B0, and the installation warrants urine continuous several times of B0 do not carry out to pelvic part 11 urinating stain cleaning and cause the bad marginal value of user impression.When b1 is less than B0, the urine of execution step S05 is discharged, and otherwise execution step S18 carries out stool flushing.
If user does not leave in step S13, then in step S17 of execution, confirm whether client presses favourable opposition button, if not pressing favourable opposition button, the step before returning to, execution step S04.If pressing favourable opposition button, execution step S18.
In step S18, carry out stool to rinse, because the time used by stool is longer, by setting the internal diameter reclaiming flexible pipe 26 between 5 to 10mm, the water in returnable 25 after the completion of generally user is defecated can be made all to flow in pelvic part 11, from washing water supply interface 13 is through washing water upper water-out portion 14 and washing water, outlet part 15 provides substantial amounts of water to moment in pelvic part 11, thus the solid dirt in closet is discharged closet through the first drain outlet sewage draining exit 124.After the completion of closet blowdown, there is flushing pipe residual water to form water shutoff at the first blowdown channel stagnant water portion 123, reach the purpose every smelly insect protected.Supplying interface 13 from washing water persistently provides a small amount of water until water shutoff highly reaches sets requirement in upper water-out portion 14 and lower outlet part 15 are to pelvic part 11, and closet returns to using front state, such as Fig. 9.
In step S19 of step S18 that continues, the urine stain due to residual before pelvic part 11 is this time cleaned completely, so record basin body urinates the B zero that stain is not continuously rinsed number of times, execution step S11 then.
To sum up, first embodiment is before Excreta falls into water seal, make at least a portion hydrops in water seal be transferred to returnable to be preserved temporarily, during preserving, a small amount of current are persistently had to return the pelvic part of closet, because the urine used time is shorter, so a small amount of water in returnable 25 is returning closet；Because the stool used time is more long, whole water is back to closet.
Left according to user or key command be rinsed, when carry out little wash in a state of excitement when using the second blow-off line that need not be additionally provided washing water, washing water is discharged, hydrops in returnable return closet as a part for water seal hydrops then.In order to make up the hydrops returning to pelvic part or drain outlet during excretion and blowdown from returnable 25, by its volume of Time Calculation, corresponding supplement washing water.As above-mentioned extreme case, if user urination time is long, but still press little rush key, closet can also reach the effect not using extra washing water to carry out blowdown, reach and little rush the purpose that water consumption is greatly lowered.
When user carries out favourable opposition, because whole water is all back to pelvic part or drain outlet, return to closet and use front state, and the blowdown of common toilet indifference, it is also possible to use of now optimizing has the drain valves of two grades of flushings and carry out favourable opposition by the first drain outlet or little rush blowdown.
This flushing mechanism also has second embodiment, as Figure 14, compare the structure of first embodiment, second embodiment increased a back-water valve (BWV) 27 being subject to central processing unit control Return water hoses 26 can be made to end or turn in Return water hoses 26, and the back-water valve (BWV) of optimization is electrical ball valve.The other structures of second embodiment are identical with the structure of first embodiment.
When hydrops utilize mechanism to work, central processing unit controls back-water valve (BWV) 27 to be in cut-off state, central processing unit controls diversion water pump 23 energising to run, the filtration through diversion portion foreign body prevention unit 21a for the hydrops in basin body, sequentially pass through diversion unit irrigating gate 17, diversion unit inlet pipe casting 22, diversion water pump 23, diversion unit water outlet pipe fitting 24, returnable priming hole 252 flow into returnable 25 at short notice, diversion can be stored by returnable 25.When central processing unit controls back-water valve (BWV) 27 to open, hydrops sequentially enter pelvic part 11 from returnable backwater hole 251, Return water hoses 26, backwater unit water inlet 18, upper water-out portion 14 or lower outlet part 15 under gravity, in order to enable water to quickly to discharge the purpose reaching the blowdown performance strengthening closet, it is preferable to provide backwater hole 251, Return water hoses 26, back-water valve (BWV) 27, the through-flow diameter of backwater unit water inlet 18 are both greater than 10mm.
First drain outlet is identical with first embodiment with the method for the second drain outlet blowdown, and here is omitted.
Illustrate referring to Figure 13 method of work corresponding to the toilet stool washing structure of the application.Same in the method for work of the application closet, stool is discharged and carries out dirt discharge by the first drain outlet, and urine is discharged and carried out dirt discharge by the second drain outlet, carries out defecation discharge in the second blowdown channel blockage using the first drain outlet.Preferably when the second blowdown channel blockage, by controlling the drain valve structure of water tank water yield for the drain valve of two grades of flushings of size can be provided in prior art；
When closet is for non-working condition, such as Fig. 9, water seal height in pelvic part 11 is as illustrated, anhydrous in returnable 25.
With reference to Figure 13, in step SS01, closet passes through microwave, infrared or allow user trigger switch perceive human body proximity, and the central processing unit of closet can drive corresponding function according to the flowchart program of Figure 13.
Then execution step SS02, starting diversion water pump 23 makes the hydrops in pelvic part 11 mobile toward returnable 25, controls back-water valve (BWV) 27 to be in cut-off state.
Then execution step SS03, judge user whether by button press little rush button, if pressed, carrying out SS04, otherwise carrying out step SS07.
In step SS04, carry out urine flushing according to customer instruction, the discharge of the liquid insults carrying out comprising urine using the second drain outlet.
With reference to Figure 15, central processing unit dredge pump 32 operates, it is partially formed that liquid insults are passed sequentially through the second blowdown channel entrance 16 by negative pressure, ascent stage 31, dredge pump 32, descending branch 33, the second drain outlet sewage draining exit 19, the first drain outlet sewage draining exit 124 flow out closet.Optimize, also allow for dredge pump 32 only short-term operation certain time, after air in the second drain outlet reduces so that forming siphonage, stop the operating of dredge pump 32a, because import the second blowdown channel entrance 16 and outlet 19a have difference in height, siphon will continue to water level in pelvic part 11 be less than 16 when, now complete the discharge of liquid insults.Again during this, at the first blowdown channel stagnant water portion 123, hydrops still keep it to flow in the hydrops in the effect of smelly insect protected, returnable 25 continue to pelvic part 11, help form the hydrops of water shutoff.
In step SS05 of step SS04 that continues, the diversion in returnable 25 is back to pelvic part.
In the process, central processing unit controls back-water valve (BWV) 27 to turn on, and hydrops sequentially enter pelvic part 11 from returnable backwater hole 251, Return water hoses 26, back-water valve (BWV) 27, backwater unit water inlet 18, upper water-out portion 14 or lower outlet part 15 to the water in returnable 25 under gravity.
In step SS06 of step SS05 that continues, washing water supplies water yield V22 that interface supplements fixed volume to closet, the volume of V22 is equal to the pelvic part hydrops not being inhaled into returnable 25 in step SS02, rely on the hydrops of the interior outflow of returnable and the washing water common guarantee of the newly-increased V22 height of the hydrops of pelvic part, closet returns to using front state, such as Fig. 9.
In step SS10 of step SS06 that continues, closet end-of-job.
If user does not press urine flush knob in step SS03, then in step SS07 then, judge whether user presses favourable opposition button.If pressed, execution step SS08, otherwise continue executing with the input that step SS03 detects user.
In step SS08, the washing water of the water in returnable and external water source is flowed to pelvic part 11 simultaneously, thus strengthening the effect that closet washes away.Because the second drain outlet is higher than the peak of the first drain outlet, so dirt will not carry out the discharge of dirt by the first drain outlet, solid state dirt passes through the first drain outlet and discharges.
In step SS09 then, supplying interface 13 from washing water persistently provides a small amount of water until water shutoff highly reaches sets requirement in upper water-out portion 14 and lower outlet part 15 are to pelvic part 11, and closet returns to using front state, such as Fig. 9.
In step SS10 of step SS09 that continues, closet end-of-job.
To sum up, second embodiment, before Excreta falls into water seal, makes at least a portion hydrops in water seal be transferred to returnable and is preserved temporarily.
Be rinsed according to user key command, when carry out little wash in a state of excitement when using the second blow-off line that need not be additionally provided washing water, washing water is discharged, hydrops in returnable return closet as a part for water seal hydrops then, reach the purpose of little punching water saving.
When user carries out favourable opposition, in returnable 25, the hydrops of interim storage and the washing water through washing water supply interface 13 inflow closet are rinsed to closet jointly, reach and strengthen the purpose that dirt is discharged, flow to the speed of closet in order to further speed up hydrops, it is possible to use pump accelerates to the backwater of backwater unit.
