Abstract

A closestool with a fast dirt discharging performance is characterized in that the shape and the inner diameter of a flushing pipeline meet the following conditions that pipeline resistance determined by the shape and the inner diameter of the flushing pipeline is small enough so that water injected from a main water outlet of the flushing pipeline has enough kinetic energy to be flushed into a siphon pipeline to form a liquid column in the siphon pipeline, and the height of a front edge of the formed liquid column is lower than the water level height inside a closestool pit. Compared with the prior art, the closestool uses the water injected by the flushing pipeline to form the liquid column required by initiating a siphon process in the siphon pipe directly, time for waiting for the water level to rise is saved, dirt discharging speed is greatly increased, the dirt is prevented from spreading in circling mode inside the closestool pit, contaminating ranges of the dirt are reduced, nauseous feeling of users is avoided, the users have better using experience, and a grade of closestool products is improved.

Description

Water closet with blowdown performance rapidly

Technical field

The utility model relates to water closet.

Background technology

All there is the slow defective of blowdown in present known water closet; Because existing water closet all is to rely on water level in the just pocket to increase to cause siphonic process; Have only water level in the just pocket to rise and highly begin to take place siphonage to the top elbows Duan Houcai that is higher than siphon piping dirt is siphoned away, the result causes whole blowdown process consuming time longer.Moreover, the just height that can rise along with the rising by height of water level of the dirt in the pocket in water level rises by high process, and in water, spiral, spread, so not only enlarged the contamination scope of dirt but also the sensation of feeling sick to the people.

The utility model content

The purpose of the utility model provides a kind of water level water closet high, that have blowdown performance rapidly that rises that need not to wait for.

The technical scheme that the utility model is taked is: the water closet with blowdown performance rapidly comprises water tank and just pocket; Water tank and just be communicated with the bath pipeline between the pocket; Just pocket is communicated with the siphon piping that is used for blowdown; The shape and the internal diameter size of said bath pipeline meet the following conditions: the shape and the resistance of ducting that internal diameter size is determined by the bath pipeline are enough little; To such an extent as to have enough kinetic energy to pour in the siphon piping from the glassware for drinking water of the main delivery port ejection of bath pipeline, in siphon piping, form fluid column, and the height in the forward position of the fluid column that forms be lower than the just interior height of water level of pocket.

As preferred forms; Said jet water spout road has two and walks around the just arm of pocket both sides; Article two, arm meets at the just main delivery port of the below formation bath pipeline of pocket; Article two, arm is spent less than 40 at the angle of the water (flow) direction of said concourse, the pipeline section that the later downstream pipeline section of top elbows section peak of said siphon piping is not bent upwards, and the bore that is opened on the water tank of said bath pipeline is 100 millimeters～110 millimeters.

Compared with prior art; The utility model is not to rely on water level in the just pocket to increase to cause siphonic process; But utilize the water of bath pipeline ejection directly in syphon, to form the required fluid column of initiation siphonic process; Therefore the utility model has saved and has waited for that water level increases the required time, has improved blowdown speed greatly.Through test, the utility model only needs 0.7 second from opening flushing valve to producing siphonage, and existing water closet is wanted 2 seconds at least.

Moreover; The utility model also has other significant advantages: dirt receives suction immediately even has all been siphoned away after siphon takes place; Therefore dirt can be in just pocket inside turn diffusion in subsequently water level rises by high process; Not only dwindle the contamination scope of dirt but also avoided making the people to produce nauseating sensation, given the better experience of people, helped promoting the class of water closet product.

The specific embodiment

Referring to Fig. 1, Fig. 2, the water closet with blowdown performance rapidly comprises water tank 1 and just pocket 2.Just pocket 2 is communicated with the siphon piping 3 that is used for blowdown.Water tank 1 and just be communicated with between the pocket 2 bath pipeline 4.As shown in Figure 2, bath pipeline 4 walks around just from being divided into 5,6, two

arms

5,6 of two arms after water tank is drawn that two rear flank of pocket meet at the just below of pocket again, forms the main delivery port 7 of bath pipeline.Arrow among Fig. 2 water (flow) direction in the pipeline 4 of representing to wash by water.

The characteristics of the utility model be the to wash by water shape and the internal diameter size of pipeline 4 meets the following conditions: enough little by the shape of bath pipeline 4 and the resistance of ducting that internal diameter size is determined; To such an extent as to have enough kinetic energy to pour in the siphon piping 3 from the glassware for drinking water of main delivery port 7 ejection of bath pipeline; In siphon piping 3, form fluid column, and the height in the forward position of the fluid column that forms is lower than the interior height of water level of just pocket 2.The available Fig. 3 of the above-mentioned meaning lays down a definition: Fig. 3 representes just to begin to cause the momentary status of siphonage; Pour from the water of main delivery port 7 ejection of bath pipeline 4 and to form fluid column 8 in the siphon piping; The height h1 that this fluid column 8 not only is full of top elbows section but also its forward position of siphon piping is lower than the height of water level h2 in the just pocket 2, thereby causes siphonage.Visible from Fig. 3; Although siphonage produces, the just height that rises that also do not have enough time of the water level h2 in the pocket 2, water level h2 arrives the height H of the top elbows section of siphon piping far away; Therefore the utility model can significantly shorten and cause the required time of siphonage raising blowdown speed.

On the basis of existing water closet; Just can make the shape and the internal diameter size of bath pipeline satisfy above-mentioned condition in order can fewly as much as possible to do to change; The utility model can be taked following change scheme on the basis of existing water closet: as shown in Figure 2, two

arms

5,6 of bath pipeline 4 are in the angle β of the water (flow) direction of concourse is limited to the scope less than 40 degree; Pipeline section as shown in Figure 1, as not to be bent upwards at the later downstream pipeline section of the top elbows section peak of siphon piping 3, and the bore D that is opened on the water tank 1 of the pipeline 4 of will washing by water as shown in Figure 1 is expanded to 100 millimeters～110 millimeters.In addition; The part of pipeline 4 of can also on the basis of existing water closet, will wash by water do slyness more; For example existing water closet has the step 9 of radial protrusion as shown in Figure 4 at the main delivery port 7 of bath pipeline 4; The utility model can remove this step, makes shape shown in Figure 5, make the bath pipeline main delivery port 7 more greatly, more smooth and easy.

Certainly, the utility model also can not receive the constraint of existing water closet structure and design a bath pipeline again.For example can change Fig. 2 into structure shown in Figure 6.4 in bath pipeline among Fig. 6 is walked around from just the one-sided of pocket, does not have bifurcated.The bath pipeline of this shape does not have in existing water closet, but as long as its shape and internal diameter size satisfy the described condition of the utility model, can make water closet have the performance of blowdown rapidly equally.Arrow among Fig. 6 water (flow) direction in the pipeline 4 of representing to wash by water.

The concrete shape of bath pipeline 4 and internal diameter size can adopt conventional hydrodynamics computational methods to draw according to the actual size and the appearance and modeling of water closet.
