Modular portable toilet with rotary agitator

A portable toilet system including a flexible waste receiving bowl supported above a lower toilet wall of the system and an agitator mechanism engaging a lower surface of the bowl to mix a reagent with waste in the bowl, the agitator mechanism comprising:

• (a) an agitator rotor shaft secured to a lower toilet wall of a chemical toilet in vertical alignment below a waste receiving bowl of the toilet system;
• (b) an agitator rotor mounted on the shaft to enable rotation of the agitator rotor about a rotor axis thereof;
• (c) an agitator roller rotatably supported the agitator rotor and having a roller axis extending radially outwardly from the agitator rotor and angled upwardly relative to the lower toilet wall;
• (d) an agitator motor engaged with the agitator rotor in such a manner as to cause rotation of the agitator rotor about the rotor axis;
• and
• (e) the agitator roller being configured in such a manner as to engage a lower surface of the bowl whereby rotation of the agitator rotor causes mixing of waste and a reagent in the bowl.

A portable toilet system including a flexible waste receiving bowl supported above a lower toilet wall of a container tub of the system and an agitator mechanism engaging a lower surface of the bowl to mix a reagent with waste in the bowl, the system further comprising:

• (a) an agitator motor engaged with an agitator mechanism of the system and operable to cause mixing movement of the agitator mechanism upon activation of the agitator motor;
• (b) an exhaust fan communicating with the container tub and operable to cause movement of air out of the container tub upon activation of the exhaust fan;
• (c) a timer coupled to the exhaust fan and the agitator motor and operable to cause activation of the exhaust fan for a selected delay interval before activation of the agitator motor upon activation of the timer;
• and
• (d) an operator switch coupled to the timer and operable to cause activation of the timer.

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.
