a manifold having an input for receiving the water output from the thermostatic valve, the manifold comprising a first water outlet controlled by a proportional control valve and a second water outlet; a washing nozzle in fluid communication with the first water outlet, and having a proportional control valve associated therewith to control the flow of water output from the washing nozzle; and a cleaning nozzle in fluid communication with the second water outlet for providing a water curtain within an interior of the toilet; wherein the water curtain flows over the washing nozzle. ## Claims ### Claim 1 A hygienic toilet comprising: a source of hot and cold water; a thermostatic valve in fluid communication with the source of hot and cold water and having a single output to deliver water at a predetermined temperature; a manifold having an input for receiving the water output from the thermostatic valve, the manifold comprising a first water outlet controlled by a proportional control valve and a second water outlet; a washing nozzle in fluid communication with the first water outlet, and having a proportional control valve associated therewith to control the flow of water output from the washing nozzle; and a cleaning nozzle in fluid communication with the second water outlet for providing a water curtain within an interior of the toilet; wherein the water curtain flows over the washing nozzle. ### Claim 2 (depends on 1) A hygienic toilet as defined in claim 1, further comprising drying means for drying water on a user. ### Claim 3 (depends on 2) A hygienic toilet as defined in claim 2, wherein the drying means comprises a means for generating and blowing heated air through a tube to an inlet provided at a rear portion of the toilet, the inlet being in fluid communication with a plurality of vent openings provided within the bowl portion of the toilet. ### Claim 4 (depends on 3) A hygienic toilet as defined in claim 3, wherein the plurality of vents comprises first and second vents arranged at opposite side portions within the bowl portion such that air expelled through the first and second vents is directed to collide to provide an upward air flow directed out of the bowl portion of the toilet, and a third vent located at a rear end of the bowl portion. ### Claim 5 (depends on 4) A hygienic toilet as defined in claim 4, wherein the first, second and third vents each comprise an elongated rectangular vent opening. ### Claim 6 (depends on 1) A hygienic toilet as defined in claim 1, further comprising a proximity sensing control valve positioned between the thermostatic valve and the manifold, the proximity sensing control valve comprising a proximity sensor mounted on a rear portion of the toilet to sense the position of a lid being in an open or closed position, wherein when the lid is in the open position, the proximity sensing control valve opens to allow water to flow to the manifold. ### Claim 7 (depends on 6) A hygienic toilet as defined in claim 6, wherein the proximity sensor is an infrared sensor. ### Claim 8 (depends on 6) A hygienic toilet as defined in claim 6, wherein the proximity sensing control valve is battery operated. ### Claim 9 (depends on 1) A hygienic toilet as defined in claim 1, wherein the washing nozzle provides a spray of water at between about 10 psi to about 50 psi via adjustment of the proportional control valve. ### Claim 10 (depends on 1) A hygienic toilet as defined in claim 1, wherein the toilet comprises a base, wherein the upper portion of the base comprises the toilet seat, the toilet seat including a contour means for providing a water-tight seal between a user and the toilet seat. ### Claim 11 (depends on 10) A hygienic toilet as defined in claim 10, wherein the contour means comprises a substantially circular or elliptical shaped opening and a front portion having an upwardly extending horn-shaped member having curved contoured sides which transition into the toilet seat upper surface, wherein the horn-shaped member engages the user above the genitals and around the groin area to prevent water from exiting the bowl portion when using the washing nozzle water spray. ### Claim 12 (depends on 11) A hygienic toilet as defined in claim 11, further comprising drying means for drying water on a user and wherein the horn-shaped member engages the user to prevent the drying air from exiting the bowl portion. ### Claim 13 (depends on 12) A hygienic toilet as defined in claim 12, further comprising a drying vent to allow drying air to escape the bowl-portion when using the drying means. ### Claim 14 (depends on 13) A hygienic toilet as defined in claim 13, wherein the drying vent is a flapper valve. ### Claim 15 (depends on 13) A hygienic toilet as defined in claim 13, wherein the drying vent is located in the horn-shaped member. ### Claim 16 (depends on 11) A hygienic toilet as defined in claim 11, further comprising a toilet lid having an opening to fit the horn-shaped member therearound. ### Claim 17 (depends on 3) The hygienic toilet as defined in claim 3, further comprising a tank and wherein the toilet includes a rim having flushing openings under the rim, and wherein, upon flushing the toilet, flushing water flows through both the flushing openings and the drying vents thereby keeping the drying vents clean from debris. ### Claim 18 (depends on 1) The hygienic toilet as defined in claim 1, wherein the predetermined temperature is between about 25° C. and 40° C. ### Claim 19 A hygienic toilet comprising: a source of water; a washing nozzle in fluid communication with the output of the source of water, the washing nozzle being mounted in a toilet bowl portion for spraying washing water from the source of water onto a user seated on the hygienic toilet; and wherein the hygienic toilet comprises a base, the upper portion of the base comprises a toilet seat having a contour means for providing a substantially water-tight seal between a user and the toilet seat when water is sprayed from the washing nozzle. ### Claim 20 (depends on 19) A hygienic toilet as defined in claim 19, wherein the contour means comprises a substantially circular or elliptical shaped opening and a front portion having an upwardly extending horn-shaped member having curved contoured sides which transition into the toilet seat upper surface, wherein the horn-shaped member engages the user above the genitals and around the groin area to prevent water from exiting the bowl portion when using the washing nozzle water spray.
