Claims20
A method for operating a portable toilet system including a flexible waste receiving bowl mounted in a container tub, an agitator mechanism engaging the bowl and including an agitator motor, an exhaust fan communicating with the tub and operable to urge air out of the tub, and a timer connected to the agitator motor and the exhaust fan, the method comprising the steps of:
- (a) activating the exhaust fan;
- (b) substantially simultaneous with activation of the fan, activating the timer to count down a selected delay interval;
- (c) at the expiration of the delay interval, activating the agitator motor.
A bowl member for supporting waste in a portable toilet device including an agitator device for causing mixing of a reagent with waste supported by the bowl member, the bowl member comprising:
- (a) a bowl wall having a bowl shape and terminating upwardly in a mounting rim;
- (b) the bowl member being formed of a flexible polymer material able to withstand repeated flexure of the wall by contact of an agitator device therewith;
- and
- (c) the bowl wall having a Shore durometer in a range of 5 to 80.
A modular portable toilet apparatus comprising:
- (a) a container tub formed by a tub bottom wall with tub side walls upstanding therefrom joined to form an open topped container, the side walls having upper ends, and sets of laterally aligned plate support members extending inwardly from the side walls;
- (b) a bowl unit removably positioned within the tub, the bowl unit including a bowl plate with a bowl opening formed therethrough and having dimensions such that the bowl plate engages the side walls of the tub and the plate support members, the bowl unit including flexible downwardly convex bowl member secured to the bowl plate in alignment with the bowl opening thereof;
- (c) an agitator unit removably supported within the tub below the bowl member and including an agitator member positioned to contact the bowl member to enable agitation of contents supported by the bowl member upon movement of the agitator member;
- (d) a power unit removably secured within the tub and including an agitation motor engaging the agitator member to cause movement of the agitator member upon activation of the agitation motor;
- and
- (e) a seat unit removable secured to the upper ends of the side walls of the tub by a hinge member and having a seat opening therethrough which is aligned with the bowl member, the seat member being capable of movement between a closed position with the seat member engaging the upper ends of the side walls and an open position angled away from the closed position.
