Abstract A water closet with a topical body washing mechanism including a water warmer mounted on the water closet and a spout pipe having a nozzle at the distal end therof for spouting warm water from the water warmer. The spout pipe is movable to and from an inoperative rest position within a bowl of the water closet, a second position advanced over the bowl to direct a jet of warm water toward the anus of the user and a third position further advanced over the bowl to direct a jet of warm water in a direction suitable for use as a bidet. An operating lever has a cam mounted on its rotational axis, the cam being contoured correspondingly to the second and third positions of the spout pipe to actuate a switch thereby starting a motor of a pump which sends forward warm water from the water warmer to the spouting nozzle. The electric circuit which includes the aforementioned motor and switch has in series a switching element and a delay circuit. When the motor switch is closed by the cam, the switching element is actuated starting the emission of water jets with a delay. Therefore, gushing of water at the second position is prevented when the spout pipe is shifted quickly from the first to the third position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
186 words
A water closet having a bowl, a pump and a topical body washing means, comprising: a container for holding washing water; a spout pipe having a jet nozzle at the distal end thereof, rotatably supported in said container and extending perpendicularly to the longitudinal center line of said bowl of said water closet. means for movably shifting said jet pipe and for shifting said jet nozzle at the distal end thereof fixably to at least three positions along said longitudinal center line of said bowl; a rotatable operating lever for shifting the position of said spout pipe between a first, second and third position; a switch operated in relation with the rotation of said operating lever to close at said second and third position of said spout pipe; a motor for driving said pump for pushing forward washing water in said container toward said spout pipe; and a motor drive control circuit comprising a switching element connected in series to said motor and said switch and a delay circuit for actuating said switching element upon lapse of a predetermined time period after actuation of said switch.
Claim 2
Dependent Claim
186 words
A water closet having a bowl, a pump and a topical body washing means, comprising: a container for holding washing water; a spout pipe having a jet nozzle at the distal end thereof, rotatably supported in said container and extending perpendicularly to the longitudinal center line of said bowl of said water closet. means for movably shifting said jet pipe and for shifting said jet nozzle at the distal end thereof fixably to at least three positions along said longitudinal center line of said bowl; a rotatable operating lever for shifting the position of said spout pipe between a first, second and third position; a switch operated in relation with the rotation of said operating lever to close at said second and third position of said spout pipe; a motor for driving said pump for pushing forward washing water in said container toward said spout pipe; and a motor drive control circuit comprising a switching element connected in series to said motor and said switch and a delay circuit for actuating said switching element upon lapse of a predetermined time period after actuation of said switch.
Claim 3
Dependent Claim
49 words
A water closet as set forth in claim 1, said spout pipe including a rotatable shaft portion and further comprising a click-motion positioning means disposed between said rotational shaft portion of said spout pipe and said container for resiliently holding said spout pipe in said second and third positions.
Claim 4
Dependent Claim
53 words
A water closet as set forth in claim 1, said delay circuit further comprising a charging circuit adapted to start charging upon actuation of said switch wherein said switching element is triggered into a conducted state at a predetermined threshold value according to the increase of the charged voltage in said charge circuit.
Claim 5
Dependent Claim
29 words
A water closet as set forth in claim 3, said delay circuit further comprising a discharge circuit for discharging charged voltage as soon as said switch is turned off.
Claim 6
Dependent Claim
97 words
A water closet as set forth in claim 3, said switching element further comprising a trigger input terminal and said delay circuit further comprising a Zener diode, a resistor and a capacitor, said Zener diode being connected to a trigger control input terminal of said switching element for determining the triggering threshold value for the increasing voltage of said charge circuit, the time constant of which is determined mainly by said resistor and said capacitor, setting the time period of delay action by the charging speed of said capacitor and the operating voltage of said Zener diode.
