Background technology
At present, the flush toilet that usually adopts comprises a water tank, the water closet with 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 some drain holes.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, seat board front end bottom correspondingly is provided with a projection, can allow the user when each the use, there is a small amount of water moistening on the water closet internal chamber wall, is difficult for enclosing dirt.But the opening direction of several drain holes on this kind flush toilet is vertical with water (flow) direction in 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 by 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, larger near the water yield in some drain holes of water tank, and along with the operation of current, arrival away from the water tank place after, the water yield in the drain hole is less, has caused in the process of flushing dirt the current skewness in the water closet, namely larger near discharging quantity of water on the internal chamber wall of water tank, less away from the discharging quantity of water on the internal chamber wall of water tank, can cause can having affected 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 continuously outflow 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 affected 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
For above the problems of the prior art, the utility model provides a kind of flush toilet that can improve blowdown power.The technical scheme that adopts is as follows:
A kind of flush toilet, comprise water tank, the water closet with the edge groove, sewage draining exit, it is characterized in that: an end of edge groove is connected in the water tank outlet, the other end is sealing, 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, during each 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 (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 be rotation towards same direction in water closet, has formed vortex, more easily takes away dirt, has further improved the effect of flushing dirt.
As a kind of preferred version of the present utility model, 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 utility model, along the water (flow) direction of edge groove, 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, clear water can continue along the edge concentrated flow moving, from other drain hole outflow, so that the distribution of the flushing water in the water closet is more even.
As another preferred version of the present utility model, 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 flow, and U is flow velocity, the S section area.
In flushing process, although there is partial flushing water continuous outfall along the edge groove to flow out, cause flow to reduce, but because section area has diminished, still can keep certain flow rate of water flow, so that still have certain flow velocity away from the current in those drain holes of water outlet of water tank, guaranteed that the water velocity of each drain hole water outlet is more even.
As another preferred version of the present utility model, the shape of drain hole can be the shapes such as star, 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 VELOCITY DISTRIBUTION on the cross section and wall and angular domain, so that flow region becomes very complicated, for flowing and heat transfer has great impact.(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 effect of dirt is taken away in the quality transmission that Secondary Flow can enhance fluid and can increase frictional force when improving bath further.(Zhan contains brightness, Cheng Jie, and Liu Jianwen etc., Secondary Flow Theory [M], Changsha, publishing house of Central South University, 2006:22).Therefore, owing to having 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 the raising blowdown power that provides of the utility model has advantages of as follows:
(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 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 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 be rotation towards same direction in water closet, has formed vortex, more easily takes away dirt, has further improved the effect of flushing dirt.
(2) because along the water (flow) direction of edge groove, the size of a plurality of drain holes increases gradually, and the sectional area of edge groove reduces gradually, and 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.
