Description
Technical field
The present invention relates to flush toilet, particularly a kind of siphon is two towards toilet.
Background technology
Advantages such as flush toilet takies because of it and occupies a narrow space, health is not stayed stink, easy to clean become a kind of sanitaryware indispensable in people's daily life.
The water tank that holds water in the flush toilet is usually located at top, cylinder body rear portion, and this water tank is used to start dunghill from the flushing of cylinder body to sewage conduct, and utilizes clear water to refill cylinder body.When the user expected flush toilet, he pressed and is positioned at the outside rinse bar of water tank, and this rinse bar is connected internally to activity chain or bar water tank.When rinse bar was pressed, chain or bar that its mobile water tank is inner, this chain or bar were used for promoting and opening flushing valve, and causes water is in water tank outflow and inflow cylinder body, thereby the flushing of startup toilet.
In flushing cycle, must satisfy roughly three purposes.The firstth, dunghill is removed to discharge conduit.The secondth, the cleaning cylinder body, removing any deposition or to adhere to the solid or the liquid wastes of cylinder surface, and the 3rd be the preparatory bath in the exchange cylinder body, thereby between using, in cylinder body, keep the water of cleaning relatively.Wherein the requirement of second cleaning cylinder body realizes through the wheel rim aquaporin that the upper periphery around the toilet cylinder body extends usually.With some or whole bath guiding through this edge gateway and flow through the opening that is positioned at wherein, with aqueous dispersion to the whole surface of cylinder body and accomplish required cleaning.
Existing hydrocone type and dash the formula toilet and have intrinsic merits and demerits.Owing to need most of air be removed so that start siphon from the following supporting leg of blow-off pipe, so siphonage-toilet tends to have less blow-off pipe, but less blow-off pipe is easier to again cause stop up.Though can utilize big blow-off pipe work and dash the formula toilet; But in cylinder body, need preparatory bath in a small amount usually; To realize by desired 100: the 1 dilution level of the pipeline rules in the most countries (that is: in flushing cycle, must 99% of the preparatory bath volume in the cylinder body removed from cylinder body and replace with new water).This little preparatory flush volume self shows as little " water seal " (water spot).The water seal of the preparatory bath in the cylinder body or superficial area play an important role in the cleaning that keeps toilet.Big water seal has increased dunghill possibility with contact with water before the ceramic surface of contact toilet.This has reduced the adhesion of dunghill and ceramic surface, is more prone to thereby toilet cleans self via flushing cycle.Therefore the formula toilet that dashes that has its little water seal often needs manually to clean cylinder body after using.
In addition, existing popular siphon jet flush toilet, a part of tank water is streamed the front end to water closet from playpipe; Go out the startup siphon backward along sitting the basin bottom part antetheca again, and then realize dunghill discharge toilet trap, the outline setting that playpipe is sat basin around toilet; And jet water course has bigger deflection will getting into position, the position water (flow) direction of sitting basin; The path of flowing through of jet water course is longer thus, and water (flow) direction changes irregular, and energy loss is bigger; Be unfavorable for starting fast siphon, influence developing result under the prerequisite of the identical water yield.
Hydrocone type water closet in the market two towards water supply volume all at 3/6 liter and 3/4.8 liter of second gear; Two flush toilet can use different water consumption to come cleaning closestool according to the needs of the dunghill of removing; To reach the purpose of water saving; Yet existing technology can't produce siphon little when dashing the shelves water supply volume less than 3 liters, thereby can not dunghill effectively be removed.
Summary of the invention
The object of the present invention is to provide a kind of siphon two towards toilet, thereby make that under the condition of the water yield seldom, improving instantaneous delivery helps to start siphon with flow velocity, siphon is two grade can't to produce siphon towards toilet little dashing to solve, and can not effectively remove the problem of dunghill.
