FR-A-2,641,561: draw and do the type flush toilet that draws water, it is characterized in that drawing the rotation of doing a pumping device and driven by the hydraulic turbine, the hydraulic turbine is driven by the press water of water system.

The water of leaving water turbine is used to clean urinal by a pipeline.

In some lavatories, used the device that reduces urinal pressure; Usually, extracting foul smell is a problem.

FR-A-2,611,722: this invention is a kind of alternative mode that extracts foul smell, it has adopted following annex: the jet pipe of at least one flat cross section, place between urinal and the flap, the air chimney of at least one flexibility has been connected adding of withdrawal device on the opening of loam cake, therefore, waste gas can be extracted under the latter's control.

Some other is referred to as " peculiar to vessel " lavatory, and the decompression that utilizes a pump to produce is introduced flushing water and discharged waste water.In this case, flap and/or seat are fluid-tight so that use decompression when pump water.Because the particular environment that use in this lavatory is necessary to adopt valve and vacuum pump.But the operation of valve must be carried out continuously, and is undertaken by the order of strictness.Special plumbing installation also need be adopted in this lavatory.

GB-1,536,773: a kind of lavatory, by loam cake, seat and urinal constitute, and urinal is water-tight when loam cake is closed, and urinal also has the bath import.This lavatory also comprises a ring sealing part, is compressed between loam cake and seat or seat and the urinal, and is placed among the groove on one of above-mentioned two parts.At the bottom of said groove has one and an inwall, form a depression.The cross section of depression is a wedge shape.The seal cross section is roughly tetragonal.This quadrangle has an acute angle, and it is positioned among the depression, and the limit that forms relative angle is flexible limit, and it is positioned on the tetragonal diagonal, and bends from a limit of seal, thereby it is contacted with another of above-mentioned two parts.Used a pump to discharge ight soil in the urinal, and made the inner partial vacuum that forms of urinal so that make flushing water enter urinal automatically by the liquid inlet.

U.S-A-2,155,286: this patent has been described the application of vacuum on toilet seat.The purpose of this patent is to reduce noise and smell, and realizes by vacuum.The realization of vacuum is to use certain material on the seat to realize.The aperture that is equipped with is used to discharge deodorant.But do not have over pressure, do not have gas-tight seal, do not improve the measure of draining yet and reduce the measure of water consumption.

US-A-2,155,551: this patent is the improvement of above-mentioned patent, and both purposes are identical with technical measures.

US-A-4,736,472: this patent has been described a kind of mechanical device, is used for keeping present going up so that prevent children hand to be put into urinal or thing is thrown into urinal toilet lid.

Toilet according to the present invention is intended to existing fixture bowl lid and/or seat are carried out less improvement, just can reach the purpose that reduces water consumption.

The toilet of the type comprises urinal, flushing system, syphon, flap and/or seat, it is characterized in that: releasing of post of bath places under the over pressure urinal, and flap and/or seat are equipped with and make under urinal is in over pressure, and the flap gland forms the device of gas-tight seal between the two when the urinal top edge, said toilet lid comprises that stop member opens when being in the gas-tight seal state to prevent it, thus the opposing over pressure.

The block piece that keeps flap to be in sealing state can be a lid itself, and the weight of lid should be greater than the weight of flushing water column, thus flap unlikely being started when the flushing water column is released into urinal, so resist over pressure.

Block piece is hook also, and it remains on airtight closed position with flap.

By means of a seal that cooperatively interacts with urinal top edge or seat edge, flap just can be at urinal and keep airtight in the over pressure process.

Seat also comprises a seal, between seat soffit and urinal top edge, can guarantee water-tight when urinal is in over pressure.

Given accompanying drawing is schematically, and non-limiting.They show a preferred embodiment of the present invention, can help to understand rapidly the present invention.

Fig. 1 is the schematic diagram of traditional type toilet, is not hermetic closed between flap and the seat wherein.

Fig. 2 is the schematic diagram that has the flush toilet of flap, and this toilet is airtight when seat and flap seal and cover urinal.

Traditional type toilet among Fig. 1 comprises urinal 1, syphon 2, flushing system 3, seat 4, flap 5.

Tradition flap 5 and seat ring 4 do not dispose and guarantee their tightness devices when the valve 6 of flushing system 3 is opened.Bath 7 must reach the discharging that a certain water level in the urinal that is higher than syphon 2 could trigger waste water.Waste water turns round and round in the bottom of urinal 1, and all waste water all are not discharged.

When bath 7 falls into urinal 1, unnecessary air will be along arrow F ₁Escape because cover 5 and seat 4 can not guarantee the tightness at urinal top edge 8 places.

About 10 liters of the average each water consumption of such traditional type toilet.

Each 4 premium on currency that only need of flush toilet of the present invention.Flap and/or seat (if any words), when closure and cover when the urinal top edge, can guarantee airtight airtight.The present invention only needs lid and/or seat are made improvements.The other parts of tradition toilet all can remain unchanged.Then as long as reduced the discharging quantity of water in the flushing system, for example can:

-adjustment float

-Jia brick

-Jia seals sand pocket

In Fig. 2, lid 9 and seat 10 parts that disposed respectively as packing ring 11,12, they can guarantee when lid 9 and seat 10 closures water-tight.

When the valve 6 of flushing system 3 is opened, when bath water column 7 falls into by the urinal of watertightness lid 9 and the seat 10 tightness closures of being brought, just produce over pressure, and cause major part i.e. discharging before bath 7 arrives urinals 1 bottom at the waste water of urinal bottom, needn't wait for that bath 7 rises to trigger the discharging action on the syphon 2.By simple over pressure, waste water can be discharged rapidly, therefore only needs more a spot of bath, sees arrow F ₂, F ₃
