Technical field
The present invention relates to a kind of flush toilet, specifically, relate to a kind of flush toilet that can improve filth-discharging effect when washing by water.
Background technology
At present, the flush toilet that adopts usually comprises a water tank, a water closet that has the edge groove, and the edge groove is connected on the water tank, and the sewage draining exit under the water closet; The two ends of edge groove are connected with water tank, and the below of edge groove has the plurality of rows water hole.For example CN201089968Y discloses a kind of flush toilet; This flush toilet water closet upper front end is provided with a groove; Be installed with a rubber balloon in the groove, corresponding with it seat board front end bottom is provided with a prominent piece, can let the user when each the use; There is low amounts of water moistening on the water closet internal chamber wall, is difficult for enclosing dirt.But water (flow) direction is vertical in the opening direction of several drain holes on this kind flush toilet and the edge groove, and drain hole is generally the identical circular port of diameter, and this design can be brought following some deficiency:
(1) flushing water is when entering into drain hole through the edge groove, and the motion aspect of current needs instantaneous changing into from horizontal movement to move both vertically, and can produce a large amount of hydraulic losses, has reduced the kinetic energy of current, causes scouring effect to reduce.
(2) because the diameter of drain hole is identical, so, bigger near the water yield in the plurality of rows water hole of water tank; And along with the operation of current, arrive away from behind the water tank place, the water yield in the drain hole is less; Caused in the process of flushing dirt, the current skewness in the water closet is promptly bigger near discharging quantity of water on the internal chamber wall of water tank; Discharging quantity of water away from the internal chamber wall of water tank is less, and can cause can influence filth-discharging effect to relatively poor away from the developing result of dirt on the internal chamber wall of water tank.
(3) in the process of bath, flushing water can pour from drain hole, and again because the internal diameter of edge slot cross-section all is evenly to equate along water (flow) direction; Water (flow) direction in the edge groove when bath; Discharge on the same cross section can constantly reduce, so the flow velocity of current also can reduce.Like this, just caused having influenced the developing result of that position reducing away from the water flow velocity in the edge groove drain hole of water tank.
Summary of the invention
To above the problems of the prior art, the invention provides a kind of flush toilet that can improve blowdown power.The technical scheme that adopts is following:
A kind of flush toilet; Comprise water tank, have water closet, the sewage draining exit of edge groove; It is characterized in that: an end of edge groove is connected in the water tank outlet; The other end is for sealing, and there are a plurality of drain holes the below of edge groove, and the water (flow) direction when the water outlet azimuth axis of drain hole and cistern water-discharging in the edge groove is acute angle.
Adopt the drain hole of this shape, when washing, current can be incline direction along drain hole and flow toward the bottom at every turn; Because the water (flow) direction when the water outlet azimuth axis of drain hole and cistern water-discharging in the edge groove is acute angle, rather than traditional vertical direction, so can reduce the hydraulic loss (Sun Wence in the flow process; Engineering fluid mechanics [M]; Dalian, publishing house of Dalian University of Technology, 1995:143-146).In addition, adopt after this kind layout, flushing water fails to be convened for lack of a quorum and in water closet, is the rotation towards same direction, has formed vortex, takes away dirt more easily, has further improved the effect of flushing dirt.
As a kind of preferred version of the present invention, above-mentioned acute angle is 30 °～60 °.
In order to solve flushing water problem pockety in water closet, as a preferred version of the present invention, the water (flow) direction of groove along the edge, the size of above-mentioned a plurality of drain holes increases gradually.So just avoid having occurred a large amount of clear water and flow out from the drain hole near the water tank exit, it is moving that clear water can continue along the edge concentrated flow, flows out from other drain hole, makes flushing water more even distribution in the water closet.
As another preferred version of the present invention, the water (flow) direction of edge groove during along draining, the sectional area of above-mentioned edge groove reduces gradually.In order to reach this technical characterictic, can adopt the upper wall surface of edge groove or the wall thickness of two medial surfaces are reached along the ever-increasing means of bath water (flow) direction.According to fluid mechanics principle, the flow velocity when the pipeline inner fluid flows and the relation of flow are:
Q=U·S
Wherein, Q is a flow, and U is a flow velocity, the S section area.
In flushing process; Partial flushing water can constantly the outfall of groove flows out along the edge though have; Cause flow to reduce, but, still can keep certain flow rate of water flow because section area has diminished; Make still have certain flow velocity, guaranteed that the water velocity of each drain hole water outlet is more even away from the current in those drain holes of water outlet of water tank.
As another preferred version of the present invention, the shape of drain hole can be shapes such as star, petal, polygon.According to Hydrodynamics Theory; In the noncircular cross section straight channel, exist the Secondary Flow phenomenon; Because the generation of Secondary Flow has changed the distribution of the shearing stress of the VELOCITY DISTRIBUTION on the cross section and wall and angular domain, make flow region become very complicated, for mobile and heat transfer great influence is arranged.(Guo second place, Bi Qincheng, what Yongqing; The experimental study [J] of Secondary Flow phenomenon in the square sectional straight channel, XI AN JIAOTONG UNIVERSITY Subject Index, 2009; 43 (7): 83-87); In addition, the mass transfer that Secondary Flow can enhance fluid and can increase frictional force is taken away the effect of dirt when improving bath further.(Zhan contains brightness, Cheng Jie, and Liu Jianwen etc., Secondary Flow principle [M], Changsha, publishing house of Central South University, 2006:22).Therefore, owing to adopted non-circular duct, when current pass through, can make current produce the turbulent extent of Secondary Flow, raising current in the improvement project, it has also further obtained enhancing for the flushing action of dirt.
To sum up, the flush toilet of raising blowdown power provided by the invention has following advantage:
(1) since when the water outlet azimuth axis of drain hole and cistern water-discharging the water (flow) direction in the edge groove be acute angle; During each the flushing; Current can be incline direction along drain hole and flow toward the bottom; Because the water (flow) direction when the water outlet azimuth axis of drain hole and cistern water-discharging in the edge groove is acute angle, rather than traditional vertical direction, so can reduce the hydraulic loss in the flow process.In addition, adopt after this kind layout, flushing water fails to be convened for lack of a quorum and in water closet, is the rotation towards same direction, has formed vortex, takes away dirt more easily, has further improved the effect of flushing dirt.
(2) since along the edge water (flow) direction of groove, the size of a plurality of drain holes increases gradually, and the sectional area of edge groove reduces gradually, current flow and velocity flow profile in water closet is more even when making flushing.
(3) drain hole in the non-circular duct of employing can make the flushing water current produce the turbulent extent of Secondary Flow, raising current, further improves developing result.
