Description
- 1. Field of the Invention
- The present invention relates to equipment in the bathroom. More particular, to a toilet.
- 2. Description of the Related Art
- In present, a toilet that works with gravity has a
wider enter 1 under a water tank and connects with adown tunnel 2 and awater passing rim 3 as disclosed in U.S. Pat. No. 5,918,325 andFIG. 1 . The toilet uses the momentum that generates from the gravitational potential energy of water and the siphon effect in thedischarging pipe 4 to provide the flush function. But, the gravitational potential energy of water can not perform the best condition in these structures. The reasons are: - 1. Under still condition, there is air left inside the
down tunnel 2 between the water tank and thewater surface 5. When the valve is opened, air will resist water flow. So, the gravitational potential energy of water can not release smoothly. According to the formula of floating power, floating power equals to the gravity of the liquid volume that is excluded and therefore the momentum will lose. This is the reason why the water tank must has water more than 1.28 gallons. Usually, the water tank must have more than 1.6 gallons water to reach the flush standard. - 2. There is a wider down tunnel that connects with the water passing rim under the water tank in present product. Therefore, when the valve is opened, water and air in the connection place of the down tunnel and the water passing rim mix together easily and air will be flushed away with water to the jet water delivery port. This phenomenon reduce the kinetic energy of water flow and produces big bubble effection. This structure is also difficult to use in a save water toilet.
- 3. Most of the toilets now are made from pottery in one unity. The precision is poor and the size of those tunnels is not easy to control. Meanwhile, there are many other limitations like material or model. So, the down tunnel has a chequered size, shape and cross-section. It is also not easy to make the down tunnel into perfect circular shape to match the request of hydrodynamics. The chequered size, shape and cross-section will reduce the water power. For example, in a basic hydrodynamics formula, an equal diameter of a pipe that is not in a circular shape and has 900 mm in cross-section and 120 mm in circumference is
-
D=4Rh -
Rh=900/120=7.5 -
D=4Rh=4×7.5=30 mm - So, the equal diameter of the pipe that has 900 mm in cross-section is 30 mm. that means the pipe equal to a perfect circular pipe that has 30 mm diameter. But, the transition efficiency of the pipe is
-
700/900=0.77 - That means the pipe has only 77% transition efficiency than a perfect circular pipe. In order to make up the momentum, the water tank needs more water.
- The object of the present invention is to provide a toilet, which can provide a good flushed efficiency and save water.
- To achieve object of the present invention, a toilet including: a bowl member having, a contraction portion, which is narrowed from a top to a bottom thereof. There is a water passing rim provided at the top rim of the contraction portion. A receiving portion is provided below the contraction portion. The receiving portion connects with a discharging pipe. A water tank places at one side of the bowl member. The water tank has an exit. A divided pipe places under the tank and connects with the exit. The divided pipe has a first exit and a second exit. A down tunnel connects with the second exit of the divided pipe in one end and with the receiving portion in the other end. The end of the down tunnel that connects with the receiving portion points to the discharging pipe and forms a jet water delivery port. The down tunnel has a downward section. A water rim duct connects with the first exit of the divided pipe in one end and the water passing rim in the other end. An air ductule, the down end of the air ductule connects with the downward section of the down tunnel and the up end of the air ductule connects with the water passing rim.

FIG. 1 is a sectional view of prior art. -
FIG. 2 is a partial sectional view of the first embodiment of present invention; -
FIG. 3 is a sectional view at line 3-3 ofFIG. 1 . -
FIG. 4 is a partial sectional view of the first embodiment of present invention shown the other side; -
FIG. 5 is a partial sectional view of the second embodiment of present invention; - Referring to
FIG. 2 toFIG. 5 , a toilet of present invention, including: - A
bowl member 10 has acontraction portion 11, which is narrowed from a top to a bottom thereof. There is awater passing rim 12 provided at the top rim of thecontraction portion 11. A receivingportion 13 is provided below thecontraction portion 11. The receivingportion 13 connects with a dischargingpipe 14. The discharging pipe has aflat section 141, anupward section 142, a convertedsection 143 and adownward section 144. - A
water tank 20 places at one side of thebowl member 10. The water tank has a valve (not shown in FIG.) and anexit 21. - The characters of present invention are that:
- A divided
pipe 30 places under the tank and connects with theexit 21. The dividedpipe 30 has afirst exit 31 and asecond exit 32. - A down
tunnel 40 connects with thesecond exit 32 of the dividedpipe 30 in one end and with the receivingportion 13 in the other end. The end of thedown tunnel 40 that connects with the receivingportion 13 points to the dischargingpipe 14 and forms a jetwater delivery port 41. The downtunnel 40 has adownward section 41, aflat section 42 and anaduncous section 43. The downtunnel 40 makes from plastic or makes of metal rather than makes from pottery. So, the inside cross-section can be au uniform and accordant circle to match the hydrodynamics and reduce the loss. - A
water rim duct 50 connects with thefirst exit 31 of the divided pipe in one end and thewater passing rim 12 in the other end. - An
air ductule 60, the down end of theair ductule 60 connects with the second half of thedown tunnel 40. The best connection position is near and over the water surface in the receivingportion 13 about 15˜20 mm. The up end of theair ductule 60 connects with thewater rim duct 50. The included angle θ between the axial of the up end and the axial of thewater rim duct 50 is better equal to or small than 90 degrees. By the way, the air can flow along with the current direction in thewater rim duct 50. - The arrangement and operation method of present invention are the same with the prior art. The gravity makes water in the water tank to flush into the divided
pipe 30 when the valve of present invention is opened. The current divides into two parts, one part goes into thewater passing rim 12 by passing through thefirst exit 31 and thewater rim duct 50. The other part goes into thedown tunnel 40 by passing through thesecond exit 32. In present invention, the inside cross-section of thedown tunnel 40 that makes from plastic or makes of metal is similar to perfect circle. It is different from the pottery of prior art. So, the inside shape and size of thedown tunnel 40 can be controlled stably and efficiently to match the hydromanics rules. Water runs more smoothly and the impulse lose can be avoided therefore. The gravity of water releases more smoothly. - Moreover, when water runs into the
down tunnel 40, air in thedown tunnel 40 will be sucked out from theair ductule 60 by the water pressure and the pump effection of thewater rim duct 50. Accordingly, air in thedown tunnel 40 will not run up and will not against the impulse of water. The gravity of water can be released smoothly without this resistance. The jetwater delivery port 41 no longer has big bubble effection. The flow rate at the jetwater delivery port 41 can be faster than prior art and therefore water quantity can be reduced. The quantity of water in a single flush can be reduced under 1 gallon and still match the flush standard. - The connection place of the
air ductule 60 of present invention is not limited. As shown inFIG. 5 , theair ductule 60 can connect with thedown tunnel 40 and thewater passing rim 12 directly and also provides the same exhaust effect. - Although the invention has been shown and described with respect to preferred embodiments thereof. It should be understood by those skilled in the art that the foregoing and other changes in the form and detail thereof may be made therein without departing from the spirit and scope of the invention.
