Description

Wash toilet device flushing mechanism

Technical field

The present invention relates to a kind of wash toilet device flushing mechanism, particularly relate to saving toilet.

Background technology

Too much easily causes urban water resource scarcity by the water capacity, increase urban sewage pipe loadings, improves municipal sewage treatment Capability Requirement.Closet is because frequency of utilization is high, so it accounts for urban water consumption greatly with water.

At present, traditional water-washing water closet all has sealing structure for water, to reach every smelly and object that is insect protected.But for user, be first with dirt, the ponding forming water seal is polluted when going to toilet, after having drained, then with a large amount of water, contaminated water and dirt discharged closet.

When defecating, dirt solid content is more, needs to consider that dirt discharges closet, and simultaneously for avoiding line clogging, dirt needs to go out certain distance.Current design uses larger drainage pipe, there being a large amount of water to flow out closet instantaneously, can ensure that dirt goes out certain distance.

When urine, dirt is liquid, and closet only needs liquid insults to discharge closet.

Carry out dirt discharge at present for different excreta differentiation, water closet is divided into favourable opposition and little punching two grades, according to the difficulty or ease that dirt is gone out, controls different by water volume, dirt to be discharged by dirt by same blow-off line.

Ponding for water seal utilizes aspect, patent is had to propose to use interim water tank again to be utilized by the ponding in toilet, but just this part water is sprayed at a high speed with pump when excrements is rinsed, for strengthening the effect of rinsing, and when to reckon without effluent be urine, the identical pipeline of unnecessary use carries out the discharge of excrements, and urine rinses the booster action also not needing pump.

According to above technical background, there is not real qualitative leap in the water saving for closet at present.

Summary of the invention

Based on solution closet joint water problem, the invention provides a kind of wash toilet device flushing mechanism, before user drains by pelvic part at least partially ponding transfer preservation avoid pollute, use second blowdown channel of differentiation is discharged urine dirt, then refluxes the ponding preserved again as a part for pelvic part ponding.

The wash toilet device flushing mechanism of the application possesses: pelvic part, has the continuing surface for catching dirt temporarily; Washing water supply port, to described pelvic part supply washing water; First blowdown channel, is connected to the below of described pelvic part, when water closet is non-usage and pelvic part jointly form ponding portion, form water seal by the ponding in this ponding portion; It is characterized in that also possessing: the second blowdown channel pelvic part dirt can discharged; And ponding utilizes mechanism, for by the introducing at least partially of described ponding, storage, discharge; Described ponding utilizes mechanism to have: returnable, is stored by the ponding of described introducing; Diversion unit, using described ponding at least partially as introducing water introduce described returnable; Backwater unit, returns to by the diversion of storing in described returnable to described pelvic part or described blowdown channel.

The wash toilet device flushing mechanism of the application's design has pelvic part, for accepting dirt, there is the washing water supply interface for connecting water source, washing water supply interface is communicated with pelvic part thus washing water can be flowed into pelvic part, after dirt falls into pelvic part, dirt can from the wall landing of basin to the import department of the first blowdown passage tube be connected to bottom pelvic part.

At non-working condition, first blowdown passage tube and pelvic part can form the structure of one or more ponding jointly, wherein ponding functionally can carry out shutoff to blow-off line at least partially, play the effect of water shutoff, thus completely cut off from the foul smell building blow-off line and the small worm that may occur.

First blowdown passage tube is compared with the second blowdown channel, and the former is comparatively thick, and its characteristic value is that diameter is about 50mm, and pelvic part functionally together form first wash dirt passage.

Second blowdown passage tube is communicated with the below of ponding, same for insect protected with every smelly consideration, closet is when non-working condition, second blowdown passage tube and pelvic part can form the structure of one or more ponding jointly, wherein ponding functionally can carry out shutoff to blow-off line at least partially, plays the effect of water shutoff.

Ponding utilizes mechanism by closet for the ponding forming water shutoff during non-working condition introduces returnable, can to preserve temporarily, the water in returnable also can be made to be back to basin body or blowdown channel pipeline in returnable.Wherein a part for ponding is even all incorporated into returnable by diversion unit, and the water introduced in returnable is returned pelvic part or blowdown channel pipeline by backwater unit.

Like this when user carries out before blowdown, ponding at least partially can be protected, avoid dirt to cause the pollution of ponding, need time recycle.

Preferably, diversion unit has a pump unit driving pelvic part ponding to flow to returnable.

In most cases, deposit possible in returnable, needs lowest surfaces in returnable to be not less than the lowest surfaces of pelvic part.Now use pump that the ponding at least partially of pelvic part is transferred to returnable, thus avoid ponding contaminated.

Preferably, diversion unit has the foreign matter prevention unit suppressing foreign matter to enter return water tank.

In closet use procedure, avoid in ponding, being mixed into hair, paper scrap, miniature solid, add the foreign matter prevention unit having and suppress foreign matter to enter return water tank in diversion unit front end, thus by ponding and impurities.

Preferably, backwater unit, is characterized in that backwater unit is that one end is not containing the pipeline of control unit.

Too much control unit more easily causes overall inefficacy, durable in use by pure pipeline configuration toilet flushing system.

Optionally, backwater unit, is characterized in that having a pump, when carrying out large shelves and rinsing, diversion is discharged fast.

When carrying out little punching and discharging without the need to washing water to dirt Accelerating Removal, but stool discharged use pump fast the water of introducing to be sprayed to the hole that the first blowdown channel is connected with pelvic part, the discharge of dirt will be promoted.

Preferably, the first blowdown channel and the second blowdown channel, is characterized in that the second blowdown path partially is less than the first blowdown path partially.

The liquid insults that may pass through due to the first blowdown channel and stool solid state dirt, so need pipeline thicker, and the discharge of urine liquid is just carried out in the second blowdown channel, less passage, so preferably the second blowdown path partially is less than the first blowdown path partially.

The method of a kind of closet work of the application is characterized in that:

When closet is non-working condition, rely on the water seal forming ponding at least partially of closet pelvic part and the first blowdown channel;

When excreta falls into before water seal, make the ponding at least partially in water seal be transferred to returnable and preserve temporarily;

Then at least can select and carry out toilet stool washing with the following method:

A part of water maximum in returnable is expelled in closet; Afterwards dirt is discharged by the second blowdown channel; In addition afterwards by returnable at least partially water be back to closet pelvic part or blowdown channel, form a part for water seal ponding.

When non-usage, by pelvic part and the first blowdown channel or only can form ponding structure by the first blowdown channel, ponding carries out water shutoff to blow-off line, reaches every the smelly object with preventing small worm.

Before the manure contamination water seal ponding of user, in ponding, water is directed to returnable by diversion unit at least partially, and the water in returnable is protected, avoids by dirt contamination.

Then can carry out following method according to flushing needs to rinse, such as urine is rinsed: first a part of water maximum in returnable is back to the cleaning that pelvic part carries out pelvic part surface, by the second blowdown channel, the liquid comprising dirt is discharged basin body again, finally current remaining in returnable are returned the ponding that pelvic part helps to be formed water shutoff.

When flowing out returnable without ponding by above method before ponding is all recovered to water tank and has rinsed, be do not need washing water to supply interface to provide extra water, the water supply volume that is under this kind of flushing is zero.When there being the water in returnable to flow out before ponding is not all recovered to returnable or flushing completes, water in returnable is less than the volume forming initial water seal, now declining appears in water seal height, makes water shutoff highly return to requirements by washing water supply interface to closet water filling.

To sum up, according to the application, one can be provided to have and to rush two grades of flushing the third purging methods not afoul and counter structure with size in current technical scheme, pollution to water seal ponding when avoiding urine, enable water seal ponding repeat to utilize, significantly reduce the water supply volume that urine is rinsed.

From Fig. 1 and Fig. 2, toilet stool washing structure has: pelvic part 11, washing water feed unit 13, first blowdown channel 12; Comprise the second blowdown channel of ascent stage 31 and dredge pump 32 and descending branch 33; Comprise inlet pipe casting 22, comprise the pump unit of diversion water pump 23, the ponding of water outlet pipe fitting 24, returnable 25, Return water hoses 26 utilizes mechanism.Wherein inlet pipe casting 22, the pump unit comprising diversion water pump 23, water outlet pipe fitting 24 form suction unit, and Return water hoses 26 functionally forms backwater unit.

Fig. 3 is the left side view for closet, from the visible section A-A of drawing, and the particular location of C-C, D-D, F-F.

Fig. 4 is the sectional drawing of A-A in Fig. 3, is also the top view of closet, and washing water supply interface 13 flows to pelvic part 11 by upper water-out portion 14 and lower outlet part 15 as seen from the figure, and wherein upper water-out portion 14 is made up of multiple aperture, in pelvic part upper limb annular spread.The water entered from backwater unit water inlet 18 can flow to pelvic part 11 by washing water upper water-out portion 14.Because backwater unit water inlet 18 internal diameter is less, the washing water flowing to returnable 25 through it is few, so do not arrange one at backwater unit water inlet 18 or Return water hoses 26 inside can stop the one-way check valve arrangement flowing to returnable 25 from washing water supply interface 13 through backwater unit water inlet 18 and Return water hoses 26, optional this one-way check valve arrangement of increase does not affect the enforcement of this method yet.

The visible second blowdown channel descending branch 33 of Fig. 5 is connected near closet sewage draining exit 124 by the second blowdown channel sewage draining exit 19, and lower outlet part 15 outlet shapes is approximately circular.

Fig. 6 is the explanation to returnable 25, returnable priming hole 252 is connected with diversion unit water outlet pipe fitting 24, internal tank is introduced in diversion, returnable backwater hole 251 is connected with Return water hoses 26, and the visible Return water hoses 26 of composition graphs 4 then connects backwater unit inlet 18 and diversion can be back to closet pelvic part.In some scheme, 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 the bottom that diversion unit intake 17 and the second blowdown channel entrance 16 are positioned at pelvic part the first blowdown channel in other words conj.or perhaps, and has the second blowdown channel foreign matter prevention unit 21b and diversion portion foreign matter prevention unit 21a respectively.The details of Figure 10 to 21b is illustrated, and the second blowdown channel foreign matter prevention unit 21b has multiple aperture, prevents larger impurity from entering the second blowdown channel.The details of Figure 11 to diversion portion foreign matter prevention unit 21a is illustrated, and diversion portion foreign matter prevention unit 21a has multiple aperture, prevents larger impurity from entering returnable 25.

Fig. 8 have expressed to have expressed from another direction be arranged in the second blowdown channel entrance 16 front end the second blowdown channel foreign matter prevention unit 21b, the second blowdown channel sewage draining exit 19, lower outlet part 15 is in the residing position of closet.

Fig. 9 is the sectional view of closet when non-usage, also embodies the internal construction that the first blowdown channel is cut open.

First blowdown channel 12 is comparatively thick, and blow-off line is similar in the market, and its characteristic diameter is 50mm, can carry out defecating or the discharge of urine.The first blowdown channel 12 optimized has ascent stage 121, descending branch 122, first blowdown channel stagnant water portion 123, closet sewage draining exit 124, and wherein the first blowdown channel stagnant water portion 123 makes closet all have water shutoff in use or non-working condition.When pelvic part ponding be introduced into returnable cause pelvic part water shutoff to disappear time, first blowdown channel 12 inside formed seal water structure still can carry out every smelly and insect protected.But it should be noted that, the first blowdown channel stagnant water portion 123 is only optimization to the present embodiment, non-essential.

Be illustrated the first wash toilet device flushing mechanism above, its method of work is described below, is first described each point of function.

When ponding utilizes institution staff, comprise the pump unit energising running of diversion water pump 23, ponding in basin body is through the filtration of diversion portion foreign matter prevention unit 21a, 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 there being water in returnable 25, ponding enters pelvic part 11 from returnable backwater hole 251, Return water hoses 26, backwater unit water inlet 18, washing water upper water-out portion 14 in turn under gravity.Because returnable backwater hole 251 aperture is less, after diversion water pump 23 stops, the ponding in returnable 25 slowly flows in pelvic part 11 within a period of time.The water flowed out from washing water upper water-out portion 14 can drain pelvic part before moistening, reduce dirt and be attached to the possibility of pelvic part, also can clean pelvic part, reduce residual at pelvic part of urine stain.Be introduced into the certain hour of water in returnable 25 after, the ponding be introduced into comes back to pelvic part 11.

When blowdown is carried out in second blowdown channel, dredge pump 32 makes impeller High Rotation Speed cause local generation vacuum suction liquid insults to flow through under the driving of electric power, liquid insults is first filtered by the second blowdown channel foreign matter prevention unit 21b, flows to building blow-off line sequentially through the second blowdown channel entrance 16, ascent stage 31, dredge pump 32, descending branch 33, second blowdown channel sewage draining exit 19, first blowdown channel sewage draining exit 124.

Use the method for the first blowdown channel blowdown and at present existing water closet is identical on the market, be described below: supply a large amount 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.For non-siphonic formula toilet, although do not produce siphon, the object of flushing still can be reached according to its prior art.

Referring to the wash toilet device flushing mechanism of Figure 12 to the application corresponding method of work be described.In the method for work of the application's closet, stool is discharged and carries out dirt discharge by the first blowdown channel, and urine is discharged and carried out dirt discharge by the second blowdown channel, uses the first blowdown channel to carry out excrements discharge when the second blowdown channel blockage.Preferred when the second blowdown channel blockage, can size of the prior art two grades flushing by the drain valve structure of control water tank water yield;

When closet is non-working condition, as Fig. 9, in pelvic part 11, water seal height as shown in the figure, anhydrous in returnable 25.

With reference to Figure 12, in step S01, closet is by microwave, infrared or allow user's 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.

The timer T performed after step S01 in the control structure of step S02 closet starts timing, and timing result is using the analysis foundation as following tripartite's surface analysis: before rinsing from returnable 25 flow to the water yield of pelvic part 11, pelvic part 11 by clean degree, confirm that user carries out urine.

Then step S03 is performed, starting diversion water pump 23 makes the ponding in pelvic part 11 move diversion action toward returnable 25, returnable 25 water level rises simultaneously, and has water to continue to flow to pelvic part 11 from returnable 25, until diversion is discharged completely in returnable 25.

Then perform step S04, judge that whether user is pressed by button and littlely rush button, if pressed, then carry out S05, otherwise carry out step S13.

In step S05, carry out urine flushing according to customer instruction, use the second blowdown channel to carry out the discharge of the liquid insults comprising urine.

With reference to Figure 15, central processing unit control of sewage disposal water pump 32 operates, be partially formed negative pressure and liquid insults flowed out closet by the second blowdown channel entrance 16, ascent stage 31, dredge pump 32, descending branch 33, second blowdown channel sewage draining exit 19, first blowdown channel sewage draining exit 124 successively.Optimize, also dredge pump 32 only short-term operation certain hour can be allowed, after air in the second blowdown channel reduces to such an extent as to forms siphonage, stop the running of dredge pump 32a, because import second blowdown channel entrance 16 and outlet 19a have difference in height, siphon will to continue in pelvic part 11 water level lower than 16 time, now complete the discharge of liquid insults.Again in this process, first blowdown channel stagnant water portion 123 place's ponding still keeps it every the effect of smelly insect protected, and the ponding in returnable 25 continues to flow in pelvic part 11, helps the ponding forming water shutoff.

Continue in the step S06 of step S05, obtain the value t1 of timer T, t1 will flow to the water yield of pelvic part 11 and estimate whether the urine stain pelvic part 11 basin body is cleaned completely before calculating flushing from returnable 25.

Continue in the step step S07 of step S06, judge whether t1 is less than the time T1 of setting, T1 is the threshold that the water flowing to pelvic part 11 from returnable 25 cleans completely to basin body all urine stains position.If the time T1 that t1 is less than setting illustrates that the urine stain of pelvic part 11 is not cleaned by enough water, so just perform step S08, otherwise perform S12.

In step S08, because the urine stain on pelvic part 11 is not cleaned completely, but a small amount of number of times does not affect use, select based on deferring to the button of user when step S04, so the number of times be not rinsed continuously by B record basin body urine stain, for subsequent step is for referencial use.

In step s 12, because urine stain residual before pelvic part 11 is cleaned completely by the ponding flowing to pelvic part 11 from returnable 25, so record basin body urine stain is not rinsed the B zero of number of times continuously.

Continue in the step S09 of step S08 or S12, due to when Return water hoses 26 and downstream line certain, can to calculate before the second blowdown channel completes blowdown from the ponding that returnable 25 flows out according to time t1, then calculate and use remaining water in returnable 25 also to need the water yield V1 for the formation of ponding provided from washing water supply interface 13 outward.

Continue in the step S10 of step S09, washing water supply interface 13 supplements to closet the water yield V1 that S09 calculates, and at least one in upper water-out portion 14 or lower outlet part 15 of washing water, discharged to pelvic part 11, makes the ponding height in pelvic part 11 rise.Diversion simultaneously 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 and the washing water of V1 volume that newly increases, the height of the ponding of common guarantee pelvic part.

Continue step S10 step S11 Counter T stop timing, t1 and t2 make zero, closet logic control returns to original state.

Continue in the step S20 of step S11, toilet stool washing controls to terminate, and closet enters holding state.

If user does not press urine flush knob in step S04, so in step S13 then, rely on the switch of microwave or triggering to judge whether user leaves, if left, perform step S14, otherwise perform step S17.

In step S14, obtain time t2, embody now and be close to from user the time that user leaves.

In step S15 then, judge that reflection user is close to the time t2 left and whether is less than setting value T2, T2 is the maximum duration of common people's shortest time of defecating or urine.When t1 is less than this setting value, can think that user has carried out urine, then first perform step S16.Otherwise auto-flushing carries out according to stool flushing, performs step S18.

In step s 16, central processing unit confirms that basin body urine stain is not rinsed number of times continuously and whether is accumulated to certain number of times, namely whether the value b1 of counter B is less than setting value B0, and the installation warrants urine continuous several times of B0 is not carried out the cleaning of urine stain to pelvic part 11 and causes the threshold that user experiences bad.The urine performing step S05 when b1 is less than B0 is discharged, otherwise execution step S18 carries out stool flushing.

If user does not leave in step S13, then in the step S17 performed, confirm whether client presses favourable opposition button, if do not press favourable opposition button, then the step before getting back to, performs step S04.If press favourable opposition button, perform step S18.

In step S18, carry out stool to rinse, owing to defecating, the time used is longer, the internal diameter of flexible pipe 26 is reclaimed between 5 to 10mm by setting, the generally user water of having defecated in rear returnable 25 can be made all to flow in pelvic part 11, in pelvic part 11, provide a large amount of water from washing water supply interface 13 outlet part 15 through washing water upper water-out portion 14 and washing water instantaneously, thus the solid dirt in closet is discharged closet through the first blowdown channel sewage draining exit 124.After closet blowdown completes, the first place of blowdown channel stagnant water portion 123 has flushing pipe residual water to form water shutoff, reaches the object every smelly insect protected.Continue to provide a small amount of water until water shutoff highly reaches setting requirement from washing water supply interface 13 in pelvic part 11 through upper water-out portion 14 and lower outlet part 15, the state before use got back to by closet, as Fig. 9.

Continue in the step S19 of step S18, because urine stain residual before pelvic part 11 is this time cleaned completely, so record basin body urine stain is not rinsed the B zero of number of times continuously, then perform step S11.

To sum up, first embodiment is before excreta falls into water seal, make the ponding at least partially in water seal be transferred to returnable to preserve temporarily, in the process of preserving, continue have a small amount of current to return the pelvic part of closet, because the urine used time is shorter, so water a small amount of in returnable 25 is returning closet; Because the stool used time is comparatively of a specified duration, the closet so whole water refluxes back.

To leave according to user or key command rinses, when carry out little wash in a state of excitement time use without the need to additionally providing the second blow-off line of washing water to be discharged by washing water, the ponding then in returnable returns the part of closet as water seal ponding.In order to make up the ponding returning to pelvic part or blowdown channel in excretion and blowdown process from returnable 25, by its volume of Time Calculation, corresponding supplementary washing water.As above-mentioned extreme case, if user's urination time is long, but still presses and littlely rush key, closet also can reach the effect not using extra washing water to carry out blowdown, reaches the little object of rushing water supply volume and significantly reducing.

When user carries out favourable opposition, because whole water is all back to pelvic part or blowdown channel, get back to closet use before state, and the blowdown of common toilet indifference, also can using of now optimizing has two grades of draining valves rinsed and carries out favourable opposition by the first blowdown channel or littlely rush blowdown.

This flushing mechanism also has the second embodiment, as Figure 14, compare the structure of the first embodiment, the second embodiment adds one and controls Return water hoses 26 can be made to end or the back-water valve (BWV) 27 of conducting by central processing unit in Return water hoses 26, and the back-water valve (BWV) of optimization is electrical ball valve.Other structures of second embodiment are identical with the structure of the first embodiment.

When ponding utilizes institution staff, central processing unit controls back-water valve (BWV) 27 and is in cut-off state, central processing unit controls the energising of diversion water pump 23 and runs, ponding in basin body is through the filtration of diversion portion foreign matter prevention unit 21a, 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 store by returnable 25.When central processing unit control back-water valve (BWV) 27 is opened, ponding enters 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 in turn under gravity, discharge the object of blowdown performance reaching and strengthen closet fast to enable water, preferably arrange backwater hole 251, Return water hoses 26, back-water valve (BWV) 27, backwater unit water inlet 18 through-flow diameter be all greater than 10mm.

First blowdown channel is identical with the first embodiment with the method for the second blowdown channel blowdown, repeats no more herein.

Referring to the toilet stool washing structure of Figure 13 to the application corresponding method of work be described.Same in the method for work of the application's closet, stool is discharged and carries out dirt discharge by the first blowdown channel, and urine is discharged and carried out dirt discharge by the second blowdown channel, uses the first blowdown channel to carry out excrements discharge when the second blowdown channel blockage.Preferred when the second blowdown channel blockage, the draining valve rinsed for size two grades can be provided in prior art by the drain valve structure controlling water tank water yield;

When closet is non-working condition, as Fig. 9, in pelvic part 11, water seal height as shown in the figure, anhydrous in returnable 25.

With reference to Figure 13, in step SS01, closet is by microwave, infrared or allow user's 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 perform step SS02, start diversion water pump 23 and the ponding in pelvic part 11 is moved toward returnable 25, control back-water valve (BWV) 27 and be in cut-off state.

Then perform step SS03, judge that whether user is pressed by button and littlely rush button, if pressed, then carry out SS04, otherwise carry out step SS07.

In step SS04, carry out urine flushing according to customer instruction, use the second blowdown channel to carry out the discharge of the liquid insults comprising urine.

With reference to Figure 15, central processing unit dredge pump 32 operates, be partially formed negative pressure and liquid insults flowed out closet by the second blowdown channel entrance 16, ascent stage 31, dredge pump 32, descending branch 33, second blowdown channel sewage draining exit 19, first blowdown channel sewage draining exit 124 successively.Optimize, also dredge pump 32 only short-term operation certain hour can be allowed, after air in the second blowdown channel reduces to such an extent as to forms siphonage, stop the running of dredge pump 32a, because import second blowdown channel entrance 16 and outlet 19a have difference in height, siphon will to continue in pelvic part 11 water level lower than 16 time, now complete the discharge of liquid insults.Again in this process, first blowdown channel stagnant water portion 123 place's ponding still keeps it every the effect of smelly insect protected, and the ponding in returnable 25 continues to flow in pelvic part 11, helps the ponding forming water shutoff.

Continue in the step SS05 of step SS04, reflux back the diversion in returnable 25 pelvic part.

In the process, central processing unit controls back-water valve (BWV) 27 conducting, and the water in returnable 25 under gravity ponding enters 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 in turn.

Continue in the step SS06 of step SS05, washing water supply interface supplements the water yield V22 of fixed volume to closet, the volume of V22 equals the pelvic part ponding not being inhaled into returnable 25 in step SS02, rely on the height of the ponding of the washing water common guarantee of ponding and the newly-increased V22 flowed out in returnable pelvic part, the state before use got back to by closet, as Fig. 9.

Continue in the step SS10 of step SS06, closet end-of-job.

If user does not press urine flush knob in step SS03, so in step SS07 then, judge whether user presses favourable opposition button.If pressed, perform step SS08, otherwise continue to perform 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 the effect that enhancing closet washes away.Because the second blowdown channel is higher than the peak of the first blowdown channel, so dirt can not carry out the discharge of dirt by the first blowdown channel, solid state dirt is discharged by the first blowdown channel.

At step SS09 then, continue to provide a small amount of water until water shutoff highly reaches setting requirement from washing water supply interface 13 in pelvic part 11 through upper water-out portion 14 and lower outlet part 15, the state before use got back to by closet, as Fig. 9.

Continue in the step SS10 of step SS09, closet end-of-job.

To sum up, the second embodiment, before excreta falls into water seal, makes the ponding at least partially in water seal be transferred to returnable and preserves temporarily.

Rinse according to user's key command, when carry out little wash in a state of excitement time use without the need to additionally providing the second blow-off line of washing water to be discharged by washing water, then the ponding in returnable returns the part of closet as water seal ponding, reaches the object of little punching water saving.

When user carries out favourable opposition, in returnable 25 temporary reservoir ponding and jointly closet is rinsed through the washing water that washing water supply interface 13 flows into closet, reach the object strengthening dirt and discharge, flowing to the speed of closet in order to accelerate ponding further, the backwater of pump to backwater unit can be used to accelerate.

Above to wash toilet device flushing mechanism and the toilet stool washing method of the application, be illustrated with reference to specific embodiment, but the present invention does not limit to and these specific embodiments.Namely, as long as possess feature of the present invention, those skilled in the art are suitably related to the technology after change to these specific embodiments and are also contained in scope of the present invention, each key element that such as aforesaid each specific embodiment possesses and its configuration, material, condition, shape, size etc., be not limited to illustrated content, can suitable change be carried out.
