Description
Technical field
The present invention relates to bathroom fields, and in particular to a kind of closestool and control method.
Background technique
Closestool is also toilet seat, is the bucket for having lid of stool and urine.The invention of closestool is referred to as a great invention, it
Solve the problems, such as that the disengaging spread is drawn in people itself food and drink.The bath principle of toilet seat is substantially Washdown type and hydrocone type currently on the market
Two kinds of major class.Divide spiral vortex type siphon and injecting type siphon in hydrocone type again.
Washdown type toilet seat is that dirt is discharged using the impulse force of water flow, and general pool wall is steeper, and water area is smaller, in this way
Waterpower is concentrated, and dirt removal is high-efficient.Its advantage is that flushing pipe is simple, path is short, and caliber is thick (general diameter is at 9 to 10 centimetres),
Urinal can be rinsed using the acceleration of gravity of water, the process of bath is short.For from dirt removal ability, with hydrocone type phase
Than due to not having water bending, direct-flushing type toilet seat is easy to sweep away biggish dirt, is not easy to result in blockage in scour process.
Its maximum defect is exactly to wash by water that sound is big, and deodorant function is poor, and it is fewer that this directly results at present the product variety on the market.
The structure of siphon wc pan is drainage pipeline in " ∽ " type, can generate certain water after drainage pipeline is full of water
Potential difference drains dirt by the suction generated in sewage pipe, and the generation of actually this suction derives from bernoulli principle.For
Generation Bernoulli effect, siphon wc pan first has to discharge water to the very high water surface, and blow-off line cannot be too big, thus
Guarantee to be completely filled with by water without gas of leaving a blank in pipeline.Therefore, first of siphon wc pan is significantly the disadvantage is that compare expense
Water at least rises to 9 liters of water or even more than ten liters with 8 every time.Second it is apparent the disadvantage is that the drainage pipe diameter of hydrocone type there was only 5,
6 centimeters or so, it is easy blocking when bath, great inconvenience is produced in life.
Siphon wc pan is also divided into spiral vortex type siphon and two kinds of injecting type siphon.The flush port of spiral vortex type siphon, which is set to, to be sat
The side of closet bottom, water flow forms vortex along pool wall when bath, understands increased water flow in this way to the flushing strength of pool wall, also increases
More conducively the dirt in closestool is discharged for the suction of siphonage.Injecting type siphon bottom in closestool increases a spray
Byroad is penetrated, is directed at the center of sewage draining exit, when bath, water a part is from the water distributing pore outflow around just circle, and a part is by jet port
It sprays, this toilet seat is quickly to wash away dirt by biggish impulsive force on the basis of siphon.
The great advantage of siphon wc pan is exactly that noisy flush is small, referred to as mute.For from dirt removal ability, siphon
Formula is easy to wash out the dirt for being attached on toilet surface, because the water of siphon is higher, odor-resistant result is better than Washdown type.Therefore now
Siphon wc pan is various in style in the market, buys toilet seat and has more choices.
From the point of view of respective principle, no matter Washdown type or hydrocone type, bath driving source both be from bath before storage
There are the water potential energies in water tank.This principle brings both sides drawback.Firstly, closestool must all have one to be higher than closestool plane
Water tank, this had both affected the beauty of closestool, also produces certain corner or spot as yet untouched by a clean-up campaign, is unfavorable for health.Secondly, being limited by space
With beautiful limitation, the height of water tank cannot be too high, at present generally within the scope of several tens cm.From the point of view of the experience of life, no matter
Washdown type or hydrocone type, the water-head within the scope of this are unable to satisfy dewatering needs in other instances, often there is closestool blocking
The phenomenon that occur.
The major defect of existing water closet shows the following aspects.First, it not can avoid the presence of water tank, influence
The beauty and health of closestool.Second, the power of drawing water that water-head generates is small, and the probability for closestool blocking occur is larger, affects day
Normal quality of the life.Third, it is more unrestrained to waste water.
