[specific embodiment]
Please join accompanying drawing 2～4, the flush toilet of the utility model preferred embodiment is described.
Like Fig. 2 is the essential structure of the utility model flush toilet.Toilet 1 comprises a bedpan 11 and a water tank 12 that places bedpan 11 back top; In water tank 12, fill with clear water and be used for washing bedpan 11; Downstream in bedpan 11 form labyrinth passage 13; Its shape approximation inverted " U " type has a delivery port 16 at the end of this labyrinth passage 13, and delivery port 16 links to each other with building gutter (not shown) downwards.The some of the clear water in the water tank 12 flows in the bedpan 11 through the aperture 14a of wheel rim filling pipe 14 bottoms.Support portion 15 is formed on bedpan 11 bottoms.
The downside that toilet 1 is placed the position of water tank 12 is provided with water filling portion 17, and this water filling portion 17 is the axisymmetric shape around central axis X, has towards the larger-diameter water filling port 18a of water tank 12 1 sides and the water supply chamber 18b that is shunk downwards by water filling port 18a.Through experiment, the radial dimension of water filling port 18a " L " was preferably between 3.62 inches (being roughly equal to 92mm) to 3.72 inches (being roughly equal to 94.5mm), can reach optimum water inlet charging efficiency.Present embodiment is of a size of 3.62 inches.Water supply chamber 18b Automatic water-filling mouth 18a downwards and extend internally and enclose and form by having training wall 18c than steep gradient.The bottom of water supply chamber 18b is the 18d of water-supplying chamber that compares water filling port 18a dimension shrinks.Be connected with training wall 18c between the 18d of water-supplying chamber and the water filling port 18a.The radial dimension of the 18b of water-supplying chamber " S " was preferably between 2.0 inches (being roughly equal to 50.8mm) to 2.12 inches (being roughly equal to 53.8mm).Present embodiment is of a size of 2.0 inches.The gradient scope of training wall 18c is between 45 degree to 75 degree basically, can fill full water supply chamber 18b, the 18d of water-supplying chamber fast to realize the water in the water tank 12.In the present embodiment, the gradient of training wall 18c is roughly 75 degree.
Wheel rim water supplement port 19a is arranged at the position near water filling port 18a, sprays the bottom that water guide mouth 19b is positioned at the 18d of water-supplying chamber.When water tank 12 in bedpan 11 during water filling, water flows to water supply chamber 18b earlier.Because water supply chamber 18b is a kind of appearance of inside contraction, so water can be full of water supply chamber 18b rapidly.Through measuring and calculating, the utility model flush toilet 1 structure can make the water-filling rate of water supply chamber 18b rise to about 62%, be superior to the water-filling rate of prior art 38%, so the water-filling effect is better.And, wheel rim water supplement port 19a with spray water guide mouth 19b at a distance of nearer, so water just begins to distribute after injecting water supply chamber 18b immediately, simultaneously to wheel rim water supplement port 19a with spray water guide mouth 19b and flow, and inject wheel rim filling pipe 14 and spray aqueduct 20.Water-filling efficient significantly improves, and structure is more compact.
Spray aqueduct 20 from upstream side towards the downstream branch to be set to from forward observation toilet 1 main body be that the 1st of right side is sprayed the 2nd of aqueduct 20a and left side and sprayed aqueduct 20b.
Downstream at the 1st injection aqueduct 20a and the 2nd aqueduct 20b; Be formed with the interflow portion 21 that is used for making these flushing water that comes self-injection aqueduct 20 interflow; Downstream in this interflow portion 21; Be formed with the rectification part 22 of flushing water rectification that is used for to the interflow, the tract of this rectification part 22 becomes jet 23.
Wheel rim filling pipe 14 also has from forward observation toilet 1 main body and is divided into the 1st filling pipe 14a on right side and the 2nd filling pipe 14b two parts in left side, and wheel rim water supplement port 19b correspondence respectively is connected the 1st filling pipe 14a and the 2nd filling pipe 14b front end.
The flush toilet 1 of this embodiment is under original state (before using).For there is air state in the upper portion in water supply chamber 18b, the 18d of water-supplying chamber and the injection aqueduct 20 to atmosphere opening, flushing water and water filling port 18a in the storage tank 12 are cut off.
During flushing, water supply chamber 18b, the 18d of water-supplying chamber are full of rapidly by the flushing water from storage tank 12, and water further divides left and right two-way to be full of injection aqueduct 20 and wheel rim filling pipe 14.Form the drainage channel that water is communicated with that accumulates in flushing water and the bedpan 11 in the storage tank 12.Then, come the flushing water of self-injection aqueduct 20 to be discharged to the labyrinth passage 13 from jet 23 with rectification part 22 through interflow portion 21.Possibly cause the gas of turbulent phenomenon when flushing water is full of water supply chamber 18b, the 18d of water-supplying chamber rapidly and sprays aqueduct 20, to be discharged by basic; Therefore the water that washes in the employed storage tank 12 is less; But the long period keeps higher level in the storage tank 12, and produces higher hydraulic pressure.Labyrinth passage 13 also receives because of the drainage channel conducting can be full of rapidly than higher hydraulic pressure, produces siphon fast, simultaneously the washing capacity grow because hydraulic pressure is higher.
As shown in Figure 4, labyrinth passage 13 has the inlet 24 that links to each other with pelvic part 11, and inlet 24 upper end comprises be connected with bedpan 11 minimum point at position of labyrinth passage 13, promptly near coal-mine 13a.Inlet 24 lower end is a partes glabra 13b relative with near coal-mine 13a.Jet 23 is to Way in inclination 45 degree of labyrinth passage 13, and jet 23 is located at the side that partes glabra 13b leans on bedpan 11.Dirt is prone to accumulate in this partes glabra 13b position, and the flushing water that sprays from jet 23 can upwards directly push dirt in the labyrinth passage 13 under hydraulic action, has improved developing result.Optimum, the vertical distance between partes glabra 13b and the near coal-mine 13a is about 2.46 feet (about 62.5mm).
From the flushing water head-on crash of the 1st, 2 injection aqueduct 20a, 20b, the pressure that spray in the aqueduct 20 rise suddenly, under original state, will accumulate in the air that sprays in the aqueduct 20 and discharge rapidly, make injection aqueduct 20 become full water at short notice.Like this; In this embodiment; Spray aqueduct 20 and just enclose full water at short notice, thus the bigger level error (hydraulic head) of accumulating water of the flushing water in the storage tank 12 and pelvic part 11 act on pelvic part 11 interior accumulate waterbornely, can access the bigger push-on force of dirt.
Then; The flushing water of interflow portion 21 aqueducts of self-injection in the future 20 is towards rectification part 22 deflections; Because the two-way flushing water that makes self-injection aqueduct 20 is interflow, portion 21 places at the interflow, cancel out each other the result so will when overlooking, be present in the horizontal inclined to one side cloth (curve inertia) that curls up the velocity flow profile that stream has; The flushing water of emitting from jet 23 becomes straight current with respect to labyrinth passage 13; Be that horizontal VELOCITY DISTRIBUTION becomes evenly, can the dirt that be used for of the energy efficient rate that flushing water had in the storage tank 12 be discharged, and therefore siphon is started earlier.The downstream of interflow portion 21 are provided with the rectification part 22 of flushing water rectification that is used for to the interflow; So the flushing water of emitting from jet 23 also becomes straight current with respect to labyrinth passage 13; Promptly VELOCITY DISTRIBUTION also becomes evenly longitudinally, correspondingly can further improve flush efficiency.
Though disclosed the specific embodiment of the utility model above, they are not the limitations of the utility model scope, know within the scope that those skilled in the art person is also contained in the utility model to the modification and the variation of the above practical implementation.
