Background technology

Due to the critical shortage of water resource, people design a lot of ways the large problem of sanitary equipment water consumption that solves.About the water consumption requirement of sanitary equipment, there is compulsory standard in many flourishing states.

In fact, the deep connotation of the water saving of sanitary equipment is not what problem of a simple water consumption, and should be to replace under double condition completely and the minimizing water consumption of trying one's best guaranteeing that bedpan washes with addle.Whether and people are very incomplete in the good and bad standard element of sanitary equipment of judgement, such as the washing force problem, just only have a kind of detection Food Red residual.And Food Red chance water just flows away, and the washing force size just can't be checked.Replacement ratio problem for another example, time swap have long have short, vary, do not have good way to go to detect yet.

By China, the water consumption standard of water-saving toilet is 3.6 liters; The water consumption standard of pan is 8 liters.In some big city municipalization sanitary equipment water saving standard access systems of China, implementation status can be quite a lot of.Because water consumption is lessly fixed, a lot of sanitary equipment be not scrub bad be exactly replace not good enough, so, people's sanitary equipment when mounted at once with the float of water intaking valve toward raising, water consumption is strengthened arbitrarily.Reason is following two aspects: one is that the water consumption standard of 3.6 liters is really tighter, and accomplish to wash and replace is very difficult fully; The 2nd, there is the defective of configuration aspects in sanitary equipment itself, no matter are low level cistern or high level cistern, and washing force is all very undesirable.

Can why the toilet of high level cistern is scrubbed and replaced in the standard water consumption situation of 3.6 liters be up to standard? reason is that water guide circle and the interior empty volume of aqueduct of toilet (comprising pan) is too large, this sky volume approximately has 2 liters, add nearly 30 on the water guide circle and scrub the hole water more than 1 liter that will pour off in the process of filling up, so, no matter water tank has many height, pressure to have much to water more than 3 liters, the potential energy of its water all discharges in this sky volume, only some weight of surplus water is slowly toward dirty, so it is all weak to scrub the water of hole and spray-hole outflow.If use 6 premium on currency, the water potential energy more than 3 liters of front has consumed, and the back only has water more than 2 liters, and water level is low, and hydraulic pressure has descended again, so effect is always not ideal enough.For this problem, I declared " pressure-guiding bedpan " patent of invention in 2007, had issued the patent certificate of 200710143460X in May, 2009 to me.This patent is exactly that to utilize the pressure of water in the pilot principle of water and dynamic closed container be not have directive principle, and the potential energy that takes full advantage of water in water tank improves the kinetic energy of scrubbing and replacing.In patent working, effect has clear improvement, but not very good.Reason is that the centuries people do not recognize the hydraulic pressure decay that in aqueduct and water guide circle, empty volume causes, and the effect of high level cistern and low level cistern does not have much differences, causes not filling more water in high level cistern yet, would rather allow water tank empty.So, water key factory does not only utilize the draining valve of high water level to sell yet.There is no this special draining valve, the hydraulic pressure potential energy of high level cistern just can't use.For this reason, I had declared the multistage pressure guide drainage valve patent the beginning of this year, was intended to solve fill water too much problem of draining to the upper limit in high level cistern as far as possible.

After the sample of multistage pressure guide drainage valve dispatches from the factory, sanitary equipment test in conjunction with pressure-guiding bedpan, the strength of rinsing is to be improved greatly, but new problem comes out again: if do the injection pipe entrance to such an extent that be of moderate size, when height is put pressure conduction in water tank to playpipe with after ducted air extrusion from the spray-hole ejection, seen very nauseating when particularly addle being arranged when bedpan; If do the injection pipe entrance bigger than normal, the mouth of pipe can cause the meaningless release of hydraulic pressure kinetic energy greatly, acts on the water of scrubbing the hole on the low side; If do the injection pipe entrance less, can cause the spray-hole insufficient water, the displacement rate variance.

Have and have no idea the injection pipe entrance is adjusted to the needs that both satisfy the spray-hole flow fully, yet do not emit again bubble when rinsing and do not form the hydraulic pressure decay? I have just carried out following trial.

Summary of the invention

The technical problems to be solved in the utility model be to provide a kind of when solving injecting type siphon displacement sanitary equipment and rinse insufficient pressure or emit the bubble problem when rinsing, be provided with the belly cross section in the playpipe middle and upper part and press the chamber greater than the storage of entrance cross-section, make storage press the air in the chamber to be compressed by current with pressure during flushing, fill out the hole water and utilize the storage that the air pressure transmission water guide is pressed to press the injection sanitary equipment thereby play minimizing.

Above-mentioned technical problem of the present utility model is to press the injection sanitary equipment to solve by the storage that a kind of following structure is provided, this storage is pressed and is sprayed sanitary equipment and comprise: at the bottom of water falling hole, water tank, overflow dam, entrance cross-section, water-guiding hole, belly cross section, playpipe water face, scrub hole, bedpan at the bottom of, spray-hole cross section, blow-off pipe, storage press chamber, aqueduct, described belly cross section is greater than entrance cross-section; Described entrance cross-section and playpipe water face are all greater than the spray-hole cross section; The lofty perch of described overflow dam is controlled within 3 centimeters with the vertical discrepancy in elevation of water-guiding hole lowest surfaces.

The existing sanitary equipment of the utility model storage pressure injection sanitary equipment and market are compared has following advantage:

The one, the efficient transmission of having guaranteed to scrub and replace hydraulic pressure.The hydraulic pressure of scrubbing is large, washes comparatively speaking totally; The hydraulic pressure that sprays is large, and the flow velocity of water is fast, impulse force is large, and the foul diadochy is strong.Storage is pressed the injection sanitary equipment and is pressed the chamber because be provided with storage in the middle and upper part of injection pipe, just solved well the injection pipe entrance large the water that will fill out many, the water of scrubbing is few, the invalid release of hydraulic pressure kinetic energy is many, entered insufficient water young, the unable displacement of spray-hole is undesirable, when entrance is of moderate size, the injection pipe Air can be emerged from spray-hole, both unhygienic also clumsy problem.The existing sanitary equipment in market are never considered the problem that hydraulic pressure transmits, and the injection pipe entrance is done very greatly on all, and two premium on currency of at first will using up during flushing remove to fill up that dell of injection pipe, have both lacked washing force and have also lacked replacing power, so water consumption always can not be fallen.

The 2nd, improved water saving, the sanitation performance of sanitary equipment.Be provided with storage in the injection pipe middle and upper part and press the sanitary equipment in chamber to greatly reduce the decay of kinetic energy in causing the hydraulic pressure transmittance process because the injection pipe entrance is large, the water that bedpan is scrubbed is many, power is large, and bedpan is washed totally.Pressure in injection pipe is large, and the flow velocity of spray-hole is fast, and kinetic energy is large.So toilet needs only 3 premium on currency, pan as long as water more than 4 liters just substantially exceeds the detection index of national regulation.And the existing sanitary equipment in market will very large water consumption could be up to standard reluctantly, toilet wants 6 liters, pan to want 8 liters.In fact, the daily water consumption of people is far above this water yield.

The 3rd, the utility model seldom consumes cost.What the invention new product was abstained from most is to increase auxiliary equipment and material.Newly-increased auxiliary equipment and material are arranged, and are at first directly to increase cost of production, and more headache is to increase maintenance cost.After particularly having increased some nonstandard materials and getting on, the older moon will be changed all long afterwards and can buy without accessory.Product of the present utility model is more as broad as long from the producting process difficulty traditional product of making peace.

Description of drawings

Describe below with reference to accompanying drawings the utility model storage and press the embodiment that sprays sanitary equipment.

Fig. 1 is that injection sanitary equipment embodiment structural profile schematic diagram is pressed in the utility model storage.

The specific embodiment

Fig. 1 shows the utility model storage and presses the specific embodiment of spraying sanitary equipment.Take toilet as example: at the bottom of water tank, 2 central authorities have water falling hole 1, be provided with overflow dam 3 on the baseplane of aqueduct 13, the lofty perch of overflow dam 3 is controlled within 3 centimeters with the vertical discrepancy in elevation of water-guiding hole 5 lowest surfaces, the lower edge of water-guiding hole 5 is distributed with scrubs hole 8, at the bottom of basin 9 the structure with conventional toilet is the same basically with the structure of blow-off pipe 11, but belly cross section 6 is greater than entrance cross-section 4; Entrance cross-section 4 and playpipe water face 7 are all greater than spray-hole cross section 10.

Owing to just making in design entrance cross-section 4 less than belly cross section 6, so, when bath, just be formed with storage between entrance cross-section 4 and playpipe water face 7 and press chamber 12.

Because the lofty perch of overflow dam 3 is controlled within 3 centimeters with the vertical discrepancy in elevation of water-guiding hole 5 lowest surfaces, when people began to wash by water, very large current can fill up water to entrance cross-section 4 and water-guiding hole 5 simultaneously after climbing over overflow dam 3 immediately.At this moment, storage presses chamber 12 Airs just to leak nowhere.Because the weight of water self, current with pressure can be at the bottom of the bedpan 9 flow to playpipe water face 7, thus the water yield that postinjection cross section 10 flows out.Like this, after storage pressed the air in chamber 12 to be pushed toward dirty water, up emitting had current with pressure to cover, and the playpipe water face 7 that walked downward is blocked, and just can only be compressed in storage and press among chamber 12.

Air in injection pipe is compressed in after storage presses chamber 12, the space in injection pipe just not water go to fill out, have the kinetic energy of pressure flow just can not form insignificant decay.Like this, scrub time of hole 8 supplying water early, pressure is large; Large from the water flow pressure of spray-hole cross section 10 ejection, form siphonage time early, displacement efficiency is high.

In specific implementation process, if carry on the location-appropriate with water falling hole 1, aqueduct 13 just can be made a pancake pipe, makes the base plane of aqueduct 13 become a plane with the design height of overflow dam 3.Like this, just do not see overflow dam 3 from drawing.

The utility model storage is pressed and is sprayed the production structure that sanitary equipment are adapted to pan equally.Just do not require although squat to have or not siphon effect on performance, the requirement of replacement result is equally very rigorous.If add a spray-hole in the entrance of basin bottom blowdown pipe, its playpipe will inevitably cause certain kinetic energy decay to current.After adopting the said structure principle, just can greatly reduce because be provided with the side effect that injection pipe brings, thereby obtain best scrubbing and replacement result.

Undoubtedly, the utility model storage presses the injection sanitary equipment that multiple conversion and remodeling can also be arranged, be not limited to the concrete structure of above-mentioned embodiment, as all changes of the different structure form of the different modes of the various structures form of overflow dam, injection pipe entrance structure and injection pipe etc.In a word, the utility model storage presses the protection domain that sprays sanitary equipment also should comprise those apparent exchanges to those skilled in the art, substitute and change shape.
