  • an improved toilet and flushing system wherein the system includes:
  • an improved toilet and flushing system substantially as described above, wherein the system utilises two flow regulators, a first flow regulator to control the flow of water to the bottom outlet, and a second flow regulator to control the flow of water to the top outlets.
  • an improved toilet and flushing system substantially as described above wherein the top outlets are positioned about the top of the bowl, such that water when exiting the outlets, travels around and down the walls of the bowl in a substantially clockwise or anti-clockwise direction.
  • the venturi effect leaves the bowl empty.
  • a method of manufacturing a toilet comprising the steps of:
  • kit for a toilet and flushing system which includes:
  • an improved toilet and flushing system wherein the system includes:
  • the toilet bowl may have a variety of configurations without departing from the scope of the present invention.
  • the toilet bowl may include a rim; a base.
  • the toilet is usually also connected to a P or S trap and is connected to a mains sewer system, septic tank or other waste reservoir in the normal manner.
  • pressured water supply refers to a source of water which can be supplied at pressure.
  • the pressured water supply may be a mains water supply.
  • the mains water supply may have a water pressure of at least substantially 30-70 PSI.
  • the water pressure of the mains water supply may be substantially 30 PSI.
  • pressured water supply may be utilised without departing from the scope of the present invention, provided they supply water to the toilet at a water pressure substantially as outlined above.
  • the water outlets may have a variety of different configurations without departing from the scope of the present invention.
  • the water outlets may be any suitable nozzle, opening or such like.
  • the tope outlets are configured to allow for water to be directed onto the tope of the wall(s) of the toilet.
  • top outlets used in the present invention may vary without departing from the scope of the present invention.
  • At least two top outlets may be utilised in the present invention.
  • three top outlets may be utilised in the present invention.
  • venturi effect refers to the reduction in pressure or vacuum created by an increase of fluid flow velocity.
  • the venturi effect may be created by:
  • venturi effect may also be achieved via other means.
  • the flow regulators may have a variety of configurations without departing from the scope of the present invention.
  • the flow regulators may comprise an on/off valve or such like. However, this should not be seen as limiting the present invention.
  • solenoid valve in the form of solenoid (on/off) valves each having an inlet and an outlet.
  • solenoid valve may be any suitable solenoid valves as would be readily apparent to a person skilled in the art.
  • the solenoid valves may substantially be the same as those used in domestic appliances such as dishwasher and the like.
  • control device may have a variety of configurations without departing from the scope of the present invention.
  • control device may consist of any device which is configured to be capable of operating at least one flow regulator in the desired manner, over a predetermined time period.
  • control device may be an electronic timing device capable of being configured to operate at least one flow regulator in a desired manner over a predetermined time period.
  • control device may be capable of being adjusted to allow for the flow regulators to be operated at different predetermined times depending on the pressure of the pressured water supply.
  • control device may be or include a suitably programmable logic unit such as a CPU.
  • control device may sense the pressure of the water supply and may adjust the predetermined rinses the flow regulator(s) remain open accordingly.
  • the predetermined time that the flow regulator is opened for the bottom outlet is substantially 8 seconds when the mains pressure is at substantially 30-60 PSI so as to allow for the bowl to be evacuated.
  • the predetermined time that the flow regulator is opened for the top outlet is substantially 3 seconds when the mains pressure is at 30-60 PSI so as to allow for the bowl to be evacuated.
  • the inventor has found these parameters to be very economical in terms of water use such that only 3-4 litres of water is required per flush.
  • the flow regulators may remain open for different predetermined times dependent on the mains pressure from which the system is being operated, and/or the order in which the flow regulators are operated.
  • water is supplied to the top and bottom outlets via separate conduits that are connected to the flow regulator(s).
  • preferred embodiments of the present invention provide an improved toilet and flushing system which may have the following advantages;
  • FIG. 1 shows a schematic side view of one preferred embodiment of the present invention.
  • FIG. 2 shows a schematic cross-sectional view of the base of the toilet system of FIG. 1 .
  • FIG. 3 shows a schematic plan view of the toilet bowl of the toilet system of FIG. 1 .
  • FIG. 4 shows a transverse cross-sectional schematic view of the rim of the toilet along the plane of line E-E on FIG. 3 .
  • FIG. 4 shows a longitudinal cross-sectional schematic view of the rim of the toilet bowl along the plane of line F-F on FIG. 3 .
  • the toilet and flushing system has a toilet bowl 2 , water 3 supplied via conduit connected to a mains water supply (not shown) having a pressure of substantially between 30 and 70 PSI.
  • the toilet bowl 2 has one bottom outlet 4 , and three top outlets 5 and a waste channel 9 .
  • the flow of water 3 from the mains water supply is regulated by solenoid valves 7 and 8 , such are commonly used in conventional dishwashers which have an inlet and outlets.
  • the solenoid valves 7 and 8 are connected via wires 71 and 81 to a control device in this form of an electronic timer 6 , such as a two cycle output timer.
  • the electronic timing device 6 In operation when the electronic timing device 6 is activated by depressing a switch 10 the electronic timing device 6 opens the solenoid valve 7 so that water 3 can be supplied via conduit 11 to the bottom outlet 4 .
  • the valve 7 remains open for a set period of time, preferably substantially 8 seconds so that the water and waste residing in the base of the bowl can be evacuated, via the venturi effect, into the waste channel 9 .
  • the electronic timing device 6 then closes the solenoid valve 7 and opens solenoid valve 8 for a set period of time, preferably substantially 3 seconds, to provide water to the top outlets 5 via conduit 12 .
  • the three top outlets 5 direct water onto the walls of the bowl 2 thereby rinsing the sides of the bowl 2 .
  • the solenoid valve 8 remains open until sufficient water has filled the base of the bowl to the desired level indicated by double headed arrow X. In general, the level indicated by arrow X is approximately 10 cm above the base of the bowl 2 .
  • the electronic timing device 6 then closes solenoid valve 8 to complete the flushing cycle.
  • FIG. 2 shows a detailed cross-sectional view of the base of the toilet bowl 2 .
  • the bottom outlet 4 is positioned within the base of the toilet bowl 2 .
  • the bottom outlet has been configured so water 3 exiting the outlet is directed onto the back of bowl 2 at point A, which is approximately 5 cm above the position of the bottom outlet 4 .
  • the bottom outlet 4 has an opening with a diameter that is reduced with respect to the diameter of conduit 11 so as to help create a venturi. Then inventor has also found that the venturi effect is further enhanced when the outlet 4 is directed at point A, on the back wall of the bowl towards the P (or S) trap.
  • the effect of the venturi is to evacuate water and waste as described above to empty the bowl 2 .
  • FIG. 3 is a plan view of the toilet bowl 2 .
  • the conduit 12 is positioned around the top of the bowl so that is can provide water to the three top outlets 5 which are positioned at regular intervals around the bowl 2 .
  • water 3 exits the top outlets 5 and is directed at an angle down onto the wall 23 of the bowl 2 and also around the bowl in the direction of dotted arrows 3 so as to create a circular (swirling) flow of water around wall 23 .
  • FIGS. 4 and 5 respectively show a transverse (refer line E-E) and longitudinal (refer line F-F) cross-sectional views of the rim of the toilet bowl shown in FIG. 3 .
  • the conduit 12 is integrally formed as part of the rim 22 of the bowl 2 .
  • the conduit 12 may in some embodiments be fitted to the rim and attached via clips, adhesive or other suitable fastening means.
