Abstract
Abstract There is disclosed a bidet seat housing in which are front and rear water jet nozzles and director members through which to pass water one or the other of the nozzles via a solenoid-operated diverter valve connected to the outlet fitting on top of an elongated horizontal water tank adjacent one end thereof, such tank having its inlet fitting on top adjacent the other end connected to a water supply line via a solenoid-operated pressure regulator. An external mode selector effects operation of one of either one of the solenoids or of a warm air blower for supplying warm air blower at the rear of the seat. The water tank contains a heater and a sensor with a temperature sensitive resistor. A control module has circuitry of which the sensor resistor is a part, and effects operation of the heater as needed to maintain water flowing through the tank at the desired temperature. Maintenance of such temperature is effected by construction of the inlet fitting so that it injects water into the top of the tank adjacent its inner surface and parallel to its axis towards the outlet end, and of the outlet fitting having an air escape opening adjacent the inner surface of the tank. A pressure switch operable from weight on the seat must be closed to permit any operations, and an over-temperature thermal switch on the tank stops the system when water temperature exceeds a predetermined level.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
277 words
A bidet water handling system comprising: a toilet seat housing having a central opening; water outlet means in said housing through which to direct water into said opening from the rear thereof; a horizontal water tank in said housing having an elongated inner cylindrical wall; an inlet fitting extending vertically into the top lateral surface of said tank adjacent one end thereof; said inlet fitting being closed at its inner end, said inlet fitting having a transverse opening directed parallel to the axis of said tank toward its other end and located adjacent the top of said wall; means including a water pressure control means connected to said inlet fitting and a supply line in said housing for supplying water under pressure to said tank; an outlet fitting extending vertically into the top lateral surface of said tank adjacent its other end; means connecting said outlet fitting to said water outlet means; and a heater in said tank adapted to heat the water flowing through said tank so as to supply heated water through said water outlet means, said outlet fitting having a transverse opening adjacent the top of said wall directed parallel to the axis of said tank in a direction away from the direction of flow from the opening in the inlet fitting, said opening in the outlet fitting functioning upon initiation of water flow to permit air in the top of the tank to be discharged through said water outlet means, and said opening in the inlet fitting functioning to cause water entering the tank to exert such stirring action as to make the water temperature the same in all portions of the tank.
Claim 2
Dependent Claim
277 words
A bidet water handling system comprising: a toilet seat housing having a central opening; water outlet means in said housing through which to direct water into said opening from the rear thereof; a horizontal water tank in said housing having an elongated inner cylindrical wall; an inlet fitting extending vertically into the top lateral surface of said tank adjacent one end thereof; said inlet fitting being closed at its inner end, said inlet fitting having a transverse opening directed parallel to the axis of said tank toward its other end and located adjacent the top of said wall; means including a water pressure control means connected to said inlet fitting and a supply line in said housing for supplying water under pressure to said tank; an outlet fitting extending vertically into the top lateral surface of said tank adjacent its other end; means connecting said outlet fitting to said water outlet means; and a heater in said tank adapted to heat the water flowing through said tank so as to supply heated water through said water outlet means, said outlet fitting having a transverse opening adjacent the top of said wall directed parallel to the axis of said tank in a direction away from the direction of flow from the opening in the inlet fitting, said opening in the outlet fitting functioning upon initiation of water flow to permit air in the top of the tank to be discharged through said water outlet means, and said opening in the inlet fitting functioning to cause water entering the tank to exert such stirring action as to make the water temperature the same in all portions of the tank.
Claim 3
Dependent Claim
64 words
The combination of claim 1, further including a temperature sensor in said outlet fitting extending into said tank, the inner end of said sensor being below the transverse opening in said outlet fitting; and means connected to said sensor and said heater to operate said heater for maintaining the water throughout said tank and passing through said water outlet means at a predetermined temperature.
Claim 4
Dependent Claim
40 words
The combination of claim 2, wherein said inlet and outlet fittings are threaded into the top of said tank, each of said inlet and outlet fittings having a respective external stem parallel to the axis of the transverse opening therein.
Claim 5
Dependent Claim
35 words
The combination of claim 2, further including second water outlet means for directing water into said opening from the front of said housing; and means connecting said outlet fitting to said second water outlet means.
Claim 6
Dependent Claim
32 words
The combination of claim 4, wherein said connecting means includes a diverter valve with a connection to said outlet fitting and respective connections to said first-mentioned and said second water outlet means.
Claim 7
Dependent Claim
49 words
The combination of claim 5, further including a fitting housing an over-temperature therman switch and threaded vertically into the top lateral surface of said tank intermediate said inlet and outlet fittings; and means connected to said thermal switch to prevent all operations if water temperature exceeds a predetermined level.
