Abstract:
1. A self-cleaning toilet system for scrubbing a toilet bowl clean with every flush, the system comprising: a cabinet mounted partially below and partially above a level of a floor with a top of the cabinet at a height of a standard toilet bowl, the cabinet comprising an enclosure with a hollow interior and a top cover having a top cabinet opening therethrough and a hinged toilet seat ring and toilet seat cover pivotally mounted over the top opening, and a vertical sealed cylinder with at least one vertical track attached to an interior of the vertical sealed cylinder; a toilet bowl movably positioned within the vertical sealed cylinder inside the cabinet below the top cabinet opening normally in a first usage position in contact with the top cover, the toilet bowl having a waste receiving bowl interior, a top bowl opening for use in communication with the waste receiving bowl interior, at least one water inlet opening adjacent to the top bowl opening, a bottom opening for drainage, at least one external protruding track riding element slidably engageable in the vertical track, and at least one toilet bowl moving arm pivotally attached to the cabinet and engaged with the track riding element, so that the toilet bowl is adapted to move from the first usage position down to a second cleaning position below the first position in response to a downward motion of the toilet bowl moving arm with the track riding element slidable in the vertical track between the two positions, and after cleaning back up to the first position in response to an upward motion of the toilet bowl moving arm; a contractible and extendable drainage tube attached at a top end to the bottom opening of the toilet bowl in communication with the waste receiving bowl interior and attached at a bottom end to a trap leading to a sewer system, the drainage tube adapted to remain attached at both ends during movement of the toilet bowl; at least one contractible and extendable water tube attached at a top end to the at least one water inlet in communication with the waste receiving bowl interior and attached at a bottom end to a water supply, the water tube adapted to remain attached at both ends during movement of the toilet bowl; a brush assembly pivotally attached to an interior of the cabinet by a brush pivot arm, the brush assembly comprising at least one rotary brush and at least one detergent sprayer, the brush assembly adapted to pivot down into the toilet bowl in the second position and clean the toilet bowl and to pivot back up away from the toilet bowl after cleaning; a pair of solenoids each attached at a first end to the cabinet, a first solenoid attached at a second end the brush pivot arm and the toilet bowl moving arm so that activation of the first solenoid activates the toilet bowl moving arm to lower the toilet bowl and activates the brush pivot arm to lower the brush assembly into the bowl, and a second solenoid attached at a second end to the brush pivot arm and the toilet bowl moving arm so that activation of the second solenoid activates the brush pivot arm to pivot the brush assembly up out of the way and activates the toilet bowl moving arm to raise the cleaned toilet bowl back up to the normal use position; a solenoid activation means positioned on the top cover of the cabinet in communication with the toilet seat cover so that closing the toilet seat cover activates the water tube to flush the toilet and activates the first solenoid and second solenoid in sequence to lower the toilet bowl, clean the toilet bowl and return the toilet bowl to the use position for a self-flushing, self-cleaning toilet.
