Valve inlet channel (31), just in time pass perpendicularly through cross bar (32), pipeline (31) is part within support (33), with cross bar is axle sleeve structure by its hole passed, when valve valve plug, connecting rod, cross bar move up and down together, pipeline (31) can ensure that valve plug can not rotate relative to cavity in valve cavity, water inlet pipe and water outlet pipe road junction when ensureing that valve plug reaches highest point outside valve plug Inlet and outlet water channel alignment valve.

Flushing pressure by-pass valve control (39) on tank for excrement pan outlet conduit, the Inlet and outlet water passage (37,72) on valve plug can also be cancelled, enough height as long as valve plug can rise under hydraulic pressure effect, valve plug is no longer covered and shutoff inlet and outlet pipe lines (37,72), if eliminate the Inlet and outlet water passage on valve plug, the vibrational power flow of cross bar (32) through pipeline (31) just can be cancelled.

Tank for excrement pan (54) is primarily of casing, piston (55), piston rod (56), inlet channel (52,50), outlet conduit (40) composition, and two inlet channel water sources are supplied by main water inlet main road (53).Inlet channel (50) is the outlet conduit of water inlet pipe road (51) after valve (461), water tank water intake pipeline (50) there is flow valve, flows per unit time when tank for excrement pan adds water can be controlled, realize being no more than in the maximum amount of water situation of water tank, realize at one's leisure adding the different water yield to water tank for difference.

Pipeline (52) is that water tank adds water pipeline, is also radiator drain road simultaneously.

Valve (461) controls water tank and adds water, and valve (46) controls water tank hydroblasting closet, and valve (39) controls the order of closet part bath.

The water through valve (46) is flowed out by tank pipe (40), a part first enters central siphon (23) in closet water spray by branching out waterpipe (27), and a part sprays by the hole for water spraying (1) by valve outlet conduit (2) arrival closet basin (3) top, pan pipeline through valve (39) again.

When closet is toilet, GRAVITY CONTROL valve valve plug pull bar one encloses the base (57) that can move up and down with on closet seat and is connected, base (57) is just equal to two gravity conductive plates of the pan of unification, and double force control valve outdoors cavity is fixedly connected with closet body (58).

When closet is urinal, linked together by two gravity conductive plates of double force control valve door, people directly or indirectly stands in above conductive plate, just can control closet very well and use.

The technical scheme that before water tank of the present invention, GRAVITY CONTROL valve, I announces is compared, the very simple and control effects of structure can better, be convenient to install, maintenance.Flushing pressure by-pass valve control (39) is compared with usual pressure valve, the losses of potential energy to the current passed through can be greatly reduced, valve can control well closet packed-piston move down and wash by water make closet rotate after, start toilet flushing basin again, thus produce larger spray after avoiding the comparatively early bath of closet basin to greatest extent, the splashing of excrements, and, time again below closet piston arrives pan pipeline, the bath of closet basin is when closestool port drops down onto closet piston, drop down onto a little relatively or reach the piston centre of rotation, thus more improve bath utilizing status.

Water pipeline (21) on closet water spray cylinder barrel, can definitely realize piston first move down, then move down gauged distance after again to impeller water spraying, piston is rotated, realize excrements and moved to lower pipeline location by piston, and be chamber pot flushing water effect comparatively good position, there is the Integral cleaning effect utilizing closet.

When closet water spray rotates, in water spray, a water spraying control valve door is arranged at central siphon (23) top, seal with closet piston cap lower end, similar to mechanical seal structure, piston cap lower part inwall is a circle planar annular, closet water spray cylinder barrel (19) and piston moves down time, valve mechanism and piston cap can seal mutually when static, rotation status.

Detailed description of the invention:

Now the closet course of work to be described to conveniently leaving closet operation process before people's convenience:

When on closet during nobody, closet gravity conduction valve (461) valve plug and valve cavity inner wall sealing, valve closing, valve (46) valve plug is separated with valve cavity inwall, valve open.Tank for excrement pan piston (55) is at water tank bottom, and pitch brace top is through water tank.

When there being people at one's leisure, human bady gravitational acts on closet GRAVITY CONTROL valve conductive plate, and valve spring is compressed, and valve (461) is opened, valve (46) closedown simultaneously.After valve (461) is opened, water tank piston (55) both sides are subject to from pipeline (52) strong with the identical hydraulic pressure of pipeline pipeline (50) simultaneously, because there is pitch brace (56) piston top, limit is stressed beyond the Great Wall compares for the stressed specific activity of the following piston of piston, go out greatly water pressure suffered by pitch brace sectional area, piston is greater than piston gravity and pitch brace and water tank frictional force by hydraulic pressuring difference up and down, so open at valve (461), under valve (46) closed condition, piston (55) moves to tank top, the water of upper piston area is flowed out by pipeline (52), water enters the water tank location below piston simultaneously, and it is different at one's leisure with people, water tank amount of water is different.

After people leaves, the gravity that human body acts on closet GRAVITY CONTROL valve conductive plate disappears, and valve spring is replied, and valve (46) is opened, valve (461) closedown simultaneously.

People leaves rear closet and starts water inlet, first water under high pressure enters container (26) through pipeline (27), enter central siphon (23) again, then the space between piston (65,66) is entered by inlet opening on central siphon, current again water also arrive interlayer cylinder barrel (19) by inlet opening (67), and start have water to spray to pan pipeline inwall from water spray interlayer cylinder barrel (19) hole for water spraying (68) gradually.Because central siphon (23) interior water intake velocity is much larger than water-jet velocity, two-piston (65, 66) between, pressure raises rapidly, the cylinder barrel interlayer that hydraulic pressure makes piston (65) and is connected, closestool port packed-piston moves down rapidly, what closestool port packed-piston arrived rapidly setting moves down minimum point, when water pipeline (21) water inlet arrive piston (66) below time, the inner water of central siphon (23) starts to spray from pipeline (21) rapidly, spray to impeller (22), impeller and closet piston start to rotate under high pressure water flow strikes, because interlayer cylinder barrel and closestool port packed-piston are axle sleeve structures, in closet water spray, central siphon (23) is bearing (69) fixed structure with sealed tube (24), so while water impact impeller makes closet seal piston rotate, central siphon (23) in closet water spray, water spray interlayer cylinder barrel (19) also rotates simultaneously, it is contrary with piston direction of rotation.

When closestool port packed-piston drop to be almost minimum altitude time, the excrements of piston face is moved to pipeline lower position by piston, piston starts to rotate, excrements is thrown off piston by centrifugal force, get rid of to pan pipeline, the a part of tail water impacting impeller, from water jet (73) ejection, is rotating and sprays to pan pipeline.

Simultaneously, after the folding process of closestool port packed-piston, annular piston (60) is touched rapidly at the bottom of piston cap lower endless, and encapsulate and progressively piston is pressed down, central siphon upper water-out hole (63) is exposed, piston (60) is moved downward to setpoint distance, the following spring of piston (62) is compressed, hole for water spraying (63) on central siphon finally all exposes, current enter piston cap inside, a part is rotating through hole for water spraying (5) and sprays to pan pipeline, the water sprayed from piston cap hole for water spraying (7) can by two-piston (4, 59) gap between arrives water pipeline (8, 14), the water arriving pipeline (14) again can respectively by groove (13, 16), pipeline (12, 15) spray, be rotating and spray to pan pipeline.The water sprayed from water jet (5) can be sprayed onto closet packed-piston and closestool port contact position, the excrements that during to rinse piston seal closestool port, closestool port likely remains.

Work more than closet moment after starting, the water arriving valve (39) also starts to enter valve cavity already, and the through hole (38) on valve plug arrives bottom valve plug, because the following lifting surface area of valve plug and top lifting surface area have pull bar (34) cross section product moment, and valve plug is greater than valve plug top by water pressure and spring (35) elastic force sum by water pressure below, valve plug starts to move up under the larger hydraulic pressure effect in below, although through a period of time of very short time, last valve plug reaches extreme higher position, valve plug intake tunnel (37), exhalant canal (72) respectively with inlet channel (29, 30), outlet conduit (2) correspondence is communicated with, current from the outlet conduit (2) of closet body by closet basin suitable for reading and end opening, pan pipeline water jet sprays, spray to and drop to extreme lower position, and the closet packed-piston rotated, piston cap.
