Patent ID: 6959459

Claim:
A body washing unit for a toilet stool, comprising: a first tube for drawing a warm water from a warm water source; a second tube being rotatably connected with the first tube, the second tube being oriented substantially in a vertical direction; a third tube being rotatably connected with the lower end of the second tube; a nozzle fixedly provided on the leading end of the third tube for ejecting a warm water to cleanse a certain portion of a body; a drive means for rotating the second tube around its own axis (A 2 ) such that the third tube is angularly displaced around the central axis (A 2 ) of the second tube between a standby position (S.P.) and a usage position (U.P.) via a motion conversion means (MC); said motion conversion means (MC) converting the rotational motion of the second tube around its own axis (A 2 ) into the rotational motion of the third tube around its central axis (A 3 ) such that the nozzle changes its orientation between its downwardly oriented posture (DP) at the standby position (S.P.) and its upwardly oriented posture (UP) at the usage position (U.P.); and a timing controller for controlling a timing of the operation of said nozzle such that cold water remaining in the first tube is discharged before warm water is ejected.
