Description

Toilet stool washing structure

Technical field

The present invention relates to water-washing type toilet closet flushing mechanism, relate in particular to the above toilet stool washing structure of water-saving folk art term or folk art term.

Background technology

Too much water easily causes urban water resource scarcity, increases urban sewage pipeline load, municipal sewage treatment Capability Requirement is improved. Closet is because frequency of utilization is high, so its water accounts for urban water consumption greatly.

In the time of stool, dirt solid content is more, for avoiding building pipe to stop up, not only needs to consider dirt discharge closet, also needs to go out certain distance. In the time of urine, dirt is liquid, and without sticking to the dirt on basin body, closet only need to be discharged closet by liquid dirt.

For the object of carrying out dirt discharge of different excreta differentiation, current toilet seat is divided into two grades of favourable opposition and little punchings, and the difficulty or ease of going out according to dirt are controlled and different made dirt pass through same blow-off line by water volume dirt is discharged.

Carry out in the research of dirt discharge in differentiation, some patent proposes urine and separately discharge of stool, but this scheme product does not have the water seal of water shutoff, does not meet the hygienic requirements of Modern Family.

Carry out in the research of dirt discharge in differentiation, some patent proposes urine to use bend pipe to discharge, stool is used directly and discharges, stool drain outlet does not have the ascent stage with respect to basin body, only rely on large-area rubber that stool drain outlet is blocked, thereby form ponding structure, then form water seal. Said method sealing surface clamp foreign matter or sealing can cause when not firm water seal disappearance, room back foul even small worm climb out of, so cannot provide stable water seal from structure, there is potential safety hazard.

Carry out in the research of dirt discharge in differentiation, some document proposes size punching to use different blow-off lines to discharge, and while size is rushed blow-off line all can be by ponding shutoff, realizes good insect protected every smelly object. But when urine blowdown for fear of favourable opposition pipe leakage, favourable opposition pipeline is blocked, and in industrial practice, hair, fish-bone, paper handkerchief that may be fallen into because of carelessness closet for the valve blocking etc. is stuck, thereby the drain outlet that causes defecating blocks, and closet cannot use.

Also have patent to record and use two different bend pipes that dirt is discharged, and there are two ponding positions, while needing user to drain, aim at stool or urine blowdown port separately. Change user's custom in the situation that this, just in case the positional fault of draining as user just may cause blow-off line to block, then cannot use.

So, utilize little punching to be easy to the feature of discharging, based on meeting hygienic requirements, do not change user's custom, stable seal water structure be provided, under the prerequisite of structure durable, structure and the dirt discharge method of inventor to closet is studied, to reaching the object of water saving.

Summary of the invention

The object of this research is to provide toilet stool washing structure, make it have following features: under the prerequisite that does not change closet user and drain custom, urine water consumption is saved, there are two passages of defecating respectively with urine blowdown, do not exist because using the urine channel blocked structure in drain outlet that causes defecating, while ensureing to damage in urine drain outlet for water-saving object, the stool and urine purging method of prior art still can be implemented, and has stable water seal thereby two kinds of dirt passing aways all have the ascent stage in the time that closet does not use.

Based on above feature, the first toilet stool washing structure that the application provides possesses: pelvic part, has the continuing surface for catch dirt temporarily; The first drain outlet, is connected in the below of described pelvic part, has the ascent stage, does not have the structure that in the time using the second drain outlet to carry out blowdown, the first drain outlet is stopped up in the first drain outlet; The second drain outlet, there is the ascent stage, common formation of the second drain outlet ascent stage and pelvic part and the first drain outlet ascent stage ponding portion in the time that toilet seat is non-use, thereby this ponding portion storage of water in the time that closet is non-use forms ponding, form water seal by this ponding, the second drain outlet is communicated with ponding portion below water seal face; It is characterized in that having:

Pump unit, drives the water of pelvic part to flow to closet sewage draining exit by the second drain outlet.

The first wash toilet utensil has pelvic part, for dirt is accepted. The first drain outlet and the second drain outlet all have the ascent stage and have jointly formed stable ponding structure with pelvic part. In the time using the second drain outlet blowdown, the first drain outlet does not have the blockage mechanism that blocks the first drain outlet, will greatly reduce the risk of the first blowdown channel jam. The second drain outlet is used for economizing on water when urine is discharged, and in the time that effluent is only urine, pump water unit drives the urine in basin body to flow to closet sewage draining exit by the second drain outlet. Thereby ensure that urine does not need rinse water can complete the discharge of dirt yet.

Preferably, the peak of the second drain outlet is higher than the peak of the first drain outlet. Like this in the time using the first drain outlet to carry out blowdown, peak is compared the preferential blowdown of low first passage and is produced siphon, the dirt of pelvic part is discharged, avoid, because of the first drain outlet and the blowdown simultaneously of the second drain outlet, causing the reduction of the easy obstruction in the second drain outlet and toilet stool washing performance.

Preferably, in the second drain outlet, there is the changes of section unit that can make the dirty channel cross-sectional area of second row change. In the time using the first drain outlet to carry out blowdown, changes of section unit diminishes the second blowdown channel cross-section and even makes the second drain outlet cut-off, more ponding and washing water all flow to sewage draining exit from the first drain outlet, avoid, because of the second drain outlet and the blowdown simultaneously of the second drain outlet, causing the reduction of the easy obstruction in the second drain outlet and toilet stool washing performance.

To sum up, the first toilet stool washing structure, in the time using the second drain outlet to carry out urine discharge, is used the pelvic part ponding that pump unit drives comprises dirt to discharge by the second drain outlet. In the time using the first drain outlet to carry out stool and urine discharge, use the second drain outlet to suppress dirt higher than the two kinds of methods in the first drain outlet and reduction the second blowdown channel cross-sectional area and flow out from the second drain outlet.

The second toilet stool washing structure that the application provides possesses: pelvic part, has the continuing surface for catch dirt temporarily; The first drain outlet, is connected in the below of described pelvic part, has the ascent stage, does not have the structure that in the time using the second drain outlet to carry out blowdown, the first drain outlet is stopped up in the first drain outlet; The second drain outlet, there is the ascent stage, common formation of the second drain outlet ascent stage and pelvic part and the first drain outlet ascent stage ponding portion in the time that toilet seat is non-use, thereby this ponding portion storage of water in the time that closet is non-use forms ponding, form water seal by this ponding, the second drain outlet is communicated with ponding portion below water seal face; It is characterized in that having pressure changeable mechanism, for the air of the gas column section of the second drain outlet is reduced; The second drain outlet is connected in the second blowdown channel entrance of described ponding portion or the first drain outlet ascent stage higher than connecting to the first drain outlet or the sewage draining exit of the second drain outlet of closet sewage draining exit; And described the second drain outlet also has: gas suppresses unit, is connected to the place of non-ascent stage in the second drain outlet, and is positioned at below described pelvic part water seal height, and inhibition gas enters the inhibition unit of the second drain outlet from the second drain outlet sewage draining exit; Gas column section, the second drain outlet being suppressed between unit and pelvic part ponding by described gas forms.

The second wash toilet utensil has pelvic part, for dirt is accepted. The first drain outlet and the second drain outlet all have the ascent stage and have jointly formed stable ponding structure with pelvic part. In the time using the second drain outlet blowdown, the first drain outlet does not have the blockage mechanism that blocks the first drain outlet, will greatly reduce the risk of the first blowdown channel jam.

The second drain outlet is used for economizing on water when urine is discharged, in the time that effluent is only urine, pressure changeable mechanism reduces the gas column section air in the second drain outlet, enter the second drain outlet even have a small amount of gas to suppress unit through gas simultaneously in this from the sewage draining exit of the second drain outlet, do not affect in the second drain outlet and the local negative pressure that forms of pressure changeable mechanism junction pipeline yet, under local decompression's effect, pelvic part ponding rises near the water surface of negative pressure position, flow out the ascent stage of the second drain outlet, reach blowdown object.

Further, pressure changeable mechanism, comprises a capacity unit, and in the time that the volume of capacity unit becomes large, internal pressure diminishes, can be by the air intake of gas column section.

Optionally, pressure changeable mechanism, comprises a pump unit, extracts air out gas column section by the work of pump unit.

Further, gas suppresses unit and is made up of the second ponding portion of the second drain outlet, and the ponding of the second ponding portion is swum the air insulated of outside sewage draining exit one side in the second ponding subordinate.

In the time using the second drain outlet to carry out blowdown, driving pump unit or make capacity unit volume become large, just can make the air in gas column section reduce, flow to outside or capacity unit, cause on the water surface at air column two ends and move until gas column section disappears, now near the water surface elevation of closet sewage draining exit one side lower than pelvic part ponding height, under Action of Gravity Field, there is siphon, water in closet flows to basin body by the second ponding portion, thereby liquid dirt is discharged from. Keep making air not enter the second drain outlet and just can make siphon continue, until dirt is all discharged.

Optionally, it is to have to make the long-pending changes of section unit changing of second channel partial cross section that gas suppresses unit, in the time that needs suppress air and enter the second drain outlet from sewage draining exit, changes of section unit diminishes the sectional area of the second drain outlet, thereby the speed that inhibition gas enters even diminishes the second drain outlet or seal.

In the time using the second drain outlet to carry out blowdown, drive and suppress the changes of section unit of unit as air and make the even cut-off that diminishes of the second blowdown path partially cross section, driving pump unit or make capacity unit volume become large, air flow outside in gas column section or capacity unit, because the second blowdown path partially cross section diminishes, the air that enters the second drain outlet from it is also less, so gas column section produces negative pressure, on the water surface that the second drain outlet ascent stage was located, move the sewage draining exit that flows to the second drain outlet from the ascent stage, then cover the flow area of changes of section unit, further improve entering the inhibition ability of gas. along with gas is constantly discharged from gas column section, gas inhibition ability improves constantly, and disappears until be positioned at the gas column section air of the second drain outlet, and now the water surface elevation of close closet sewage draining exit one side is lower than pelvic part ponding height. in the situation that guaranteeing not make to enter air in the second drain outlet, stop driving pump unit or variodenser unit, the negative pressure that acts on changes of section unit disappears, and now also can drive changes of section unit, makes the aisle spare of the second drain outlet become large. there is siphon in the second two ends, drain outlet, dirt is discharged under Action of Gravity Field. keep making air not enter the second drain outlet and just can make siphon continue, until dirt is all discharged.

Optionally, it is to be made up of the smallest passage cross section pipeline of discharging section that gas suppresses unit, and its passage section area is not more than the area of diameter 30mm circle; Wherein connecting on the second drain outlet sewage draining exit and the second drain outlet is discharge section with the passage at pressure changeable mechanism connection place. The circular cross-sectional flow area that preferred use diameter is 10mm.

In the time using the second drain outlet to carry out blowdown, driving pump unit is extracted the air in gas column section out, the now air flow outside in vacuum gas column section, the drain outlet of the second drain outlet and building is communicated with, under local decompression's effect of pressure changeable unit, portion of air enters the second drain outlet and is discharged by pump, part pelvic part ponding rises and flows into drain outlet under suction function, owing to constantly there being gas from then on to enter at smallest passage place, current cannot flow out, causing lodging in discharge section and the water surface of the second drain outlet ascent stage constantly rises, until the gas in the second drain outlet is drained, the gas only sucking from the second drain outlet sewage draining exit, now stop driving pump unit, in the situation that guaranteeing not make to enter air in the second drain outlet, stop driving pump unit or variodenser unit, the negative pressure that acts on pipeline place, smallest passage cross section disappears, ponding starts to flow to the sewage draining exit of the second drain outlet, under Action of Gravity Field, there is siphon in the second two ends, drain outlet, dirt is discharged. keep making air not enter the second drain outlet and just can make siphon continue, until dirt is all discharged.

In this process, if the area in smallest passage cross section increases, can cause flowing into gas velocity in the second drain outlet fast in the second drain outlet sewage draining exit, then need pump unit to have stronger gas to discharge ability. If the area in smallest passage cross section is too small, can cause easily being stopped up from the impurity of pelvic part ponding. Under the balance of pump unit and obstruction risk, the area of section of suggestion smallest passage cross section pipeline is not more than the area of diameter 30mm circle, the circle that preferred use diameter of section is 10mm also suppresses in the interior increase of the second blowdown channel entrance 161 structure that foreign matter passes through, and can make the Risk Reduction stopping up and the exhaust capacity of pump unit can significantly not increased.

Preferably, pressure changeable mechanism can also be in the time being used the first drain outlet blowdown, and the gas column section in the second drain outlet increases gas. Cause like this water surface distance change at gas column section two ends to be difficult to greatly connection, dirt cannot be discharged by the second drain outlet, avoids, because of the first drain outlet and the blowdown simultaneously of the second drain outlet, causing the reduction of the easy obstruction in the second drain outlet and toilet stool washing performance.

Existing toilet stool washing structure explanation: if Fig. 1 is a kind of existing toilet stool washing structure, there is pelvic part 11, inner the first drain outlet 12, washing water supply port 13, upper rinse part 14, lower rinse part 15, closet sewage draining exit 17 without its passage being diminished and comprising for the first drain outlet ascent stage 121.

Wherein pelvic part 11 is for accepting dirt, the first drain outlet 12 is connected in pelvic part 11 belows for carrying out the discharge of stool and urine, thereby the common ponding structure ponding in the time that closet is non-use that forms of the first drain outlet ascent stage 121 and pelvic part 11 forms water shutoff, closet also has the washing water supply port 13 being connected with washing water, in the lower supply unit 15 that the upper supply unit 14 that washing water supply port 13 and the multiple apertures that circumferentially distribute at pelvic part inner edge form and at least one spout form, at least one is communicated with provides washing water for pelvic part 11, closet sewage draining exit 17 is for being expelled to building pipe by washing water.

The first toilet stool washing structure

Contrast existing toilet stool washing structure and Fig. 1 referring to Fig. 2, the pelvic part 11 that the first toilet stool washing structure has with shown in Fig. 1, existing toilet stool washing structure function is identical, the first drain outlet 12, washing water supply port 13, upper rinse part 14, lower rinse part 15, the closet sewage draining exit 17. that comprised for the first drain outlet ascent stage 121 also have: the second drain outlet 16 of enough blowdowns, and wherein the second drain outlet 16 has; Be positioned at the second blowdown channel entrance 161 of pelvic part 11 bottoms or the first drain outlet ascent stage 121 or lower outlet part 15, the second drain outlet ascent stage 162, the second drain outlet sewage draining exit 164, connect the tube connector 163 of the second drain outlet ascent stage 162 and the second drain outlet sewage draining exit 164, can drive pelvic part ponding to flow out by 212, the second drain outlets, pump unit of the second drain outlet outflow thinner than the first drain outlet. Preferably, pump unit is not for allowing susceptible to plugging membrane pump.

In the time of non-use, pelvic part 11, the second drain outlet ascent stage 162, common formation of the first drain outlet ascent stage 121 ponding portion store the washing water entering from washing water supply port, form the object of water seal thereby reach, as closet ponding face PL in Fig. 2, realized to building pipe every smelly insect protected.

When user carries out after urine, while using the second drain outlet to carry out blowdown, pump water unit 212 is opened, and the liquid that pelvic part is comprised to urine and ponding flows to closet sewage draining exit 17. through the second blowdown channel entrance 161, the second drain outlet ascent stage 162, tube connector 163, the second drain outlet sewage draining exit 164 in turn

When user defecate or urine after, while using the first drain outlet to carry out blowdown, by washing water supply port 13 in upper rinse part 14 or lower rinse part 15 at least one, flow to pelvic part 11, pelvic part ponding face PL in Fig. 2 rises, in the second drain outlet 16 and the first drain outlet 12, all may there is dirt to discharge, thereby reach the object that dirt is discharged.

After blowdown completes, rinse water supply port 13 supplies water to pelvic part 11, and pelvic part ponding face PL rises to preset value, again forms water seal.

Further, the performance while carrying out blowdown in order to improve in the first drain outlet 12, avoids the interference of performance between two drain outlets, in the time using the first drain outlet blowdown, can select the method that the second drain outlet blowdown is suppressed.

Shown in Fig. 2, in flushing mechanism, used two implementation methods to reach the inhibition to the second drain outlet blowdown, but arbitrary independent implementation method can reach identical inhibition object, all belongs in the application's scope.

First implementation method is that the peak of the second drain outlet peak higher than the first drain outlet is set.

As shown in Figure 2, the peak STP that the second drain outlet 16 is set higher than the peak FTP. of the first drain outlet 12 in the time that pelvic part ponding face PL rises, the first drain outlet 12 takes the lead in carrying out the dirt discharge siphonage that even takes the lead in producing, thereby causing water surface rising velocity to decline even reduces, so just make the water reduction of flowing through in the second drain outlet even stop, thereby reach the object that suppresses blowdown.

Second implementation method is in the second drain outlet 16, to be provided with the changes of section unit that the second blowdown channel cross-section is diminished.

As shown in Figure 2, in the time using the first drain outlet blowdown, do not work in pump unit, the degree of spring 213 in being compressed on a small quantity, diaphragm 214 blocks the water inlet of pump unit, the second blowdown path partially area of section is 0, the second state of drain outlet 16 in being cut off, and reaches the object of the second suppressed blowdown in drain outlet in the time of the first drain outlet blowdown.

In the time of the second drain outlet blowdown, the vane rotary in pump unit, water inlet end produces suction, and diaphragm 214 is inhaled to be opened, and now spring 213 continues compressedly, and the second 16Zhong cross section, drain outlet becomes and becomes greatly conducting, thereby can carry out the discharge of liquid dirt.

The second toilet stool washing structure

Contrast existing toilet stool washing structure and Fig. 1 referring to Fig. 3, Fig. 4, Fig. 5, wherein Fig. 3 and Fig. 5 represent two embodiments of the second toilet stool washing structure, and Fig. 4 is that scheme shown in Fig. 3 is used the second drain outlet to carry out the schematic diagram of blowdown. As seen from the figure, the pelvic part 11 that the second toilet stool washing structure has with shown in Fig. 1, existing toilet stool washing structure function is identical, the first drain outlet 12, washing water supply port 13, upper rinse part 14, lower rinse part 15, the closet sewage draining exit 17. that comprised for the first drain outlet ascent stage 121 also have: the second drain outlet 16 that also can blowdown, and wherein 16 have; Be positioned at the second blowdown channel entrance 161 of pelvic part 11 bottoms or the first drain outlet ascent stages 121 bottom or lower outlet part 15, the second drain outlet ascent stage 162, the second drain outlet sewage draining exit 164, connect the tube connector 163 of the second drain outlet ascent stage 162 and the second drain outlet sewage draining exit 164, for suppressing to enter from the second drain outlet 164 the gas inhibition unit of the second drain outlet, wherein the second blowdown 164 is lower than the second blowdown channel entrance 161, gas suppresses unit lower than pelvic part water seal face, and the second drain outlet is thinner than the first drain outlet.

Flushing mechanism also has the pressure changeable mechanism for the air of the air shell of column of the second drain outlet 16 is reduced, and the second drain outlet that described gas column section is suppressed between unit and pelvic part ponding by gas forms.

In the time of non-use, pelvic part 11, the second drain outlet ascent stage 162, common formation of the first drain outlet ascent stage 121 ponding portion store the washing water entering from washing water supply port, thereby form ponding and reach the object that forms water seal, as closet ponding face PL in Fig. 3, realized to building pipe every smelly insect protected.

When user carries out after urine, while using the second drain outlet to carry out blowdown, drive pressure changeable mechanism to start the Bas Discharged in gas column section, to gas column Duan Eryan, one end is ponding, and the other end is to suppress the air that air enters the second drain outlet to suppress unit, and the air entering when gas column section is less than the air of discharge, gas column section two ends produce negative pressure, cause pelvic part ponding cross the second drain outlet ascent stage 161 flow to gas suppress unit. Continue to discharge the air of gas column section, until all air are discharged from, now because pelvic part ponding height suppresses the height at unit place higher than gas, and be liquid between the two, under gravity differential pressure action, suppress from second channel water inlet to air to produce siphonage unit, due to the former, to compare the latter high, in the time ensureing to enter the second drain outlet without air from pressure changeable mechanism, siphon will continue, until pelvic part the second blowdown channel entrance stops while entering air, to reach the object that pelvic part dirt is discharged.

When user defecate or urine after, while using the first drain outlet to carry out blowdown, by washing water supply port 13 rinse part 14 or clean at least one in several lower rinse parts 15 on washing water, flow to pelvic part 11, pelvic part ponding face PL moment in Fig. 3 and Fig. 5 rises, in the time that the rate of climb is enough fast, in the second drain outlet 16 and the first drain outlet 12, all can produce siphon dirt is discharged, reach the object that dirt is discharged.

Now describe for first embodiment of Fig. 3 and the represented the second toilet stool washing structure of Fig. 4, wherein Fig. 3 is the profile of the non-use shape of closet body, and Fig. 4 is the profile that uses the second drain outlet to carry out blowdown.

In this toilet stool washing structure, the second drain outlet is formed and is suppressed to suppress unit from 164 air gases that enter by the second ponding portion 221, by forming gas column section 222 away from the confined space between the ponding face SSFL of closet sewage draining exit in the second drain outlet ascent stage ponding face SUL and the second ponding portion, now capacity unit 223 is in free state, air pressure inside and atmospheric pressure are basic identical, the ponding face SSFL away from closet sewage draining exit of the second ponding portion 221 and highly approaching near the ponding face SSNL of sewage draining exit.

When user carries out after urine, while using the second drain outlet to carry out blowdown, as Fig. 4, pull drive rod 225 that the lower part of capacity unit 223 is moved downward, use the fold of the capacity unit 223 of rubber making to be opened, volume strengthens, pressure diminishes, the air of gas column section is inhaled into capacity unit 223 by connecting pipe 224 under differential pressure action, the ponding face SSFL away from closet sewage draining exit of the second ponding portion 221 and the ponding face SUL of the second drain outlet ascent stage 162 rise until merge and enter connecting pipe 224 inside of connection pressure changeable mechanism and the second drain outlet simultaneously, form new water level face SWL, meanwhile pelvic part ponding face PL and the ponding face SSFL away from closet sewage draining exit decline, for the second drain outlet 16, import water level is higher than outlet water level, in the time keeping gas not enter 16 inside, the second drain outlet, dirt will continue to discharge, until there is air to enter the second drain outlet 16 after emptying. in order to ensure that gas does not enter the second blowdown path 16 inside from connecting pipe 224, is provided with the level sensor 232 for responding to connecting pipe 224 water level inside at connecting pipe 224 places. in flushing process, remind user or central processing unit that drive rod 225 is driven when detecting the signal of anhydrous time feedback, otherwise stop driving and keep drive rod position. after all dirts of pelvic part are discharged, air enters pipeline through the second blowdown channel entrance 161, is atmospheric pressure at the second ponding two ends, away from the ponding face SSFL of closet sewage draining exit and highly equal near the ponding face SSNL of sewage draining exit. now discharge and drive pull bar 225, the variodenser unit 223 deforming returns to original state under elastic restoring force effect.

When user defecate or urine after, while using the first drain outlet to carry out blowdown, by washing water supply port 13 rinse part 14 or clean at least one in several lower rinse parts 15 on washing water, flow to pelvic part 11, pelvic part ponding face PL moment in Fig. 3 rises, in the time that the rate of climb is enough fast, in the second drain outlet 16 and the first drain outlet 12, produces siphon dirt is discharged.

After blowdown completes, rinse water supply port 13 supplies water to pelvic part 11, and pelvic part ponding face PL rises to preset value, again form water seal, in this process, SUL rises, so but 222 other outlets of gas column section are the reduction of sealing state volume, its inner air is in confined state. Because variodenser unit 223 and connecting line 224 internal capacities are much larger than the SUL volume reducing that rises, the relation being inversely proportional to according to pressure in gas equation and volume, the pressure that can learn gas column section 222 is slightly larger than atmospheric pressure, and SUL is a little less than PL so, and SSFL is a little less than SSNL.

Following three kinds of inhibition implementation methods can be selected:

With reference to figure 4, first inhibition method, the peak STP that the second drain outlet 16 can be set higher than the peak FTP. of the first drain outlet 12 in the time that pelvic part ponding face PL rises, the first drain outlet 12 takes the lead in carrying out the dirt discharge siphonage that even takes the lead in producing, thereby causing water surface rising velocity to decline even reduces, so just make the water reduction of flowing through in the second drain outlet even stop, thereby reach the object that suppresses blowdown.

Second inhibition method is in the second drain outlet 16, to be provided with the changes of section unit that the second blowdown channel cross-section is diminished. In the time that pelvic part water level raises, the second blowdown channel cross-section is diminished, suppress the blowdown of the second drain outlet. In some implementation method, in tube connector 163, be connected into a ball valve as changes of section unit, in the time using the second drain outlet blowdown, valve opening makes the second drain outlet conducting. In the time using the first drain outlet blowdown, valve closing makes the second drain outlet cut-off.

The 3rd inhibition method, in the time using the first drain outlet 12 blowdown, compression capacity unit 223, make the pressure rise of gas column section, the second drain outlet ascent stage ponding face SUL and second drain outlet the second ponding portion all decline away from the ponding face SSFL of closet sewage draining exit, what such the second drain outlet became is difficult to conducting, thereby reaches the object that suppresses blowdown.

Now describe for second embodiment of the represented the second toilet stool washing structure of Fig. 5, wherein Fig. 5 is the profile of closet non-working condition.

In this implementation method, be the capacity unit 223 as pressure changeable mechanism in first embodiment of the second toilet stool washing structure to be replaced with to the pump unit 231 that the air in gas column section can be extracted out, that optimizes is connected by exhaust outlet 234 gas outlet of pump unit simultaneously with sewage draining exit 17. Pump unit can be can be by air sucking-off then by the self-priming water pump of water sucking-off, can be also air pump or other similar structures of bleeding.

Understanding for convenience following content can contrast with reference to figure 3 and Fig. 4.

In the time of non-use, pelvic part 11, the second drain outlet ascent stage 162, common formation of the first drain outlet ascent stage 121 ponding portion store the washing water entering from washing water supply port, reach and form the object of water seal thereby form ponding, realized to building pipe every smelly insect protected.

When user carries out after urine, while using the second drain outlet to carry out blowdown, pump unit 231 is opened when the air in the gas column section 222 forming by ascent stage ponding face SUL in the second drain outlet 16 with away from the ponding face SSFL of closet sewage draining exit is extracted out, the water level at gas column section two ends occurs to move until be interconnected simultaneously, and on move to the second drain outlet more than 16, rise to the new water level face SWL after the water surface is communicated with by the ponding face SUL of the ponding face SSFL away from closet sewage draining exit and the second drain outlet ascent stage 162, meanwhile pelvic part ponding face PL and the ponding face SSFL away from closet sewage draining exit decline, for the second drain outlet 16, import water level is higher than outlet water level, in the time keeping gas not enter 16 inside, the second drain outlet, dirt will continue to discharge, until there is air to enter the second drain outlet 16 after emptying. in order to ensure that gas does not enter the second blowdown path 16 inside from connecting pipe 224, be provided with the level sensor 232 of induction connecting pipe 224 water level inside at connecting pipe 224 places, when detecting driving pump unit exhaust when anhydrous or strengthening the exhaust velocity of pump unit, otherwise drive at a slow speed or stop driving. after all dirts of pelvic part are discharged, air enters pipeline through the second blowdown channel entrance 161, is atmospheric pressure at the second ponding two ends, and SSFL and SSNL are highly equal. now stop driving pump unit, liquid remaining in connecting pipe 224, to the second ponding portion 221, flows to closet sewage draining exit 17. then
