Abstract
The present invention relates to a new closet water flushing system generating high-speed water flows for drawing excrement by the existing water supply water pressure, which has a unique water flushing period different from the water flushing period of the existing water flushing closet. A closet of the present invention is composed of a seal water tank, a water inlet valve for connecting a water supply system and the water tank and a discharging valve discharging water in the water tank to the closet, wherein the water tank is empty at ordinary times. The water flushing period is started when a user opens the water inlet valve, the water flows into the water tank by the water supply pressure, and water inlet compresses trapped air in the water tank until the required pressure is achieved. The water inlet valve is automatically closed, the discharging valve is opened, and the water is discharged to the closet by the pressure of the compressed air. The new closet water flushing system provides high-speed flushing water and largely saves the water, and the performance of the new closet water flushing system is superior to that of the traditional closet.
Description
The present invention relates to novel water closet, more specifically to the pressure flushing system of water closet.
The operating principle of water closet depends on two primary elements, promptly drains trap and syphon.Drain trap and forms by letting out dirty road, let out dirty road and be made of the overfall that then forms to lower tube section towards upper runner, this set prevents that the interior water of toilet basin body from draining, because of the water surface is lower than overfall in the pond of toilet basin bottom formation at ordinary times.The water seal effect is played in the pond, toilet basin body and dirty bleeder dirt pipe are separated, hold excreta simultaneously, prevent that also excreta from directly contacting with the basin body surface, that lets out dirty road extends to basin bottom basically to lower tube section, so that can produce siphonage under certain high-velocity flow.
With regard to traditional flush toilet, the water of putting into basin body at first overflows to overfall from basin body and causes overflow, and when continuing bath, overflow increases, up to the flow that forms post stream in lower tube section of letting out dirty road.Under this state, then set up siphonage.The suction that siphonage produces is taken excreta away from basin body.In fact, at present all water closets all rely on siphonage that excreta is taken away.Because siphonage only just can be set up under certain discharge, so must be provided with big water gaging.The family expenses water closet will be emitted big water gaging for giving essential discharge from water tank.The water tank of gravity water closet is placed in the basin body upper end usually and communicates with atmosphere.Now, the gravity water closet is in the U.S. and the most universal in the world.
Recently, be developed into the family expenses pressurized flush toilet, it utilizes the existing pressure that supplies water to cause the bath effect.This system is made up of the sealing cistern of pressure store water, supplies water with effective increase.After bath, water tank can automatically be filled with again.When hydraulic pressure moved the water to flow into water tank, the air pressurized of holding back in the case was pressed case and is increased until reaching predetermined pressure.Then, block water supply by pressure regulator, water in the case and compressed air remain to bath next time.Because water tank volume and entrapped air amount are all fixing, so the water yield of the each bath of the control that case is pressed decision.
Compare with traditional gravity bath, the pressure flushing system has many advantages.The speed of discharging water at first of this system is much higher than the speed that gravity flow obtains.Total energy used in the pressure bath is doubly a lot of greater than the gravity bath.Therefore, the pressure bath almost can be set up required siphonage immediately, and only needs considerably less water, just can cause high efficiency developing result.
Yet existing pressure flushing system has several not satisfied characteristics.Existing pressure bath uses conventional methods wash water is pre-stored in the water tank at ordinary times.Therefore need control the situation of water tank pressurized exactly.Because water tank need be stored lot of energy chronically, water tank needs the special safety of structure design to guarantee to operate of strengthening, and also increases the expense of producing simultaneously.
The other problem of existing pressure flushing system is that existing systems need be brought quantitative fresh air into when each water tank is refilled water, so that the air of once washing by water and being taken away before replenishing.In order to control the air of bringing into, current must be controlled with nozzle in the quite accurate venturi.This has increased the complexity of system again, installs and maintenance cost thereby increase.In use, the user need open the pressure flushing valve.Because the flushing valve cross-sectional area is big and hydraulic pressure is big, so will apply bigger power on flushing valve.For the convenience of the users, power need be reduced so that valve is opened easily.Ways of addressing this issue is to adorn a control valve that starts the Water flushing for cistern valve at present.This makes the pressure flushing system become complicated and more unreliable more again.Therefore, although there is superior performance in the pressure water tank system, still fail so far to popularize.
Main purpose of the present invention aims to provide a kind of new type closet flushing system, and it utilizes the existing pressure energy that supplies water, the performance that has reduced the consumption of water and improved a kind of closet flushing.
