Abstract
A trailer type mobile sanitary apparatus includes a housing that forms an interior space having a flushable toilet and a wash basin. The trailer type mobile sanitary apparatus further includes a wash basin drainage system and a septic tank that is separated from the wash basin drainage system and includes a decomposer configured to separate liquids from solids for a separate discharge. The housing securely positioned on a tray type trailer with a septic tank being formed in the tray type trailer. The tray type trailer further includes a technical room with an electric system and a water supply system.
Claims20
A trailer-type mobile sanitary apparatus comprising:
- a housing mounted on a trailer, the housing defining an interior sanitary space including a flushable toilet and a wash basin;
- a freshwater tank configured to supply water to the toilet and wash basin, the freshwater tank being positioned on or adjacent to the housing roof or on a lateral support frame of the trailer;
- a water-supply system comprising a pump configured to deliver water from the freshwater tank to at least the toilet and the wash basin;
- a septic tank positioned below the housing or within a tray-type trailer portion, the septic tank having a capacity sized to receive waste from the toilet and wash basin;
- a decomposer within the septic tank, wherein the decomposer includes a metal plate having a plurality of punch holes configured to separate liquid waste from solid waste such that the liquid waste passes through the punch holes into a lower region of the septic tank while the solid waste remains above the metal plate;
- and
- a separate discharge outlets including a first outlet for the liquid waste and a second outlet for the solid waste, each configured to be independently emptied.

A technical room for a mobile sanitary system, comprising:
- a structural frame formed of a plurality of steel members defining a floor, sidewalls, and a roof, the frame dimensioned to mount on a trailer adjacent to a toilet cabin;
- a plurality of steel cladding panels secured to the structural frame, the cladding panels forming an enclosed compartment and including openings configured for electrical and water-line penetrations;
- a freshwater-tank interface mounted to an upper portion of the technical room, the interface comprising:
- a connection port configured to receive water from a freshwater tank positioned above the technical room;
- and
- a float-valve assembly positioned within the compartment and configured to regulate inflow from the freshwater tank;
- a water-supply subsystem disposed within the technical room and comprising a booster pump fluidly connected to the freshwater-tank interface and configured to pressurize water delivered to a toilet cabin;
- an electrical subsystem disposed within the technical room and comprising:
- an electrical cabinet containing a solar-charge controller, a transfer switch configured to selectively receive power from a solar source or an external AC source, and a plurality of circuit breakers dedicated to cabin devices;
- a battery electrically coupled to the electrical cabinet and contained within the technical room;
- and
- at least one voltage converter configured to supply regulated electrical output to the booster pump and cabin devices;
- a water-outlet conduit extending through one of the cladding panels and configured to supply water from the booster pump to the toilet cabin;
- an electrical conduit passage extending through one of the cladding panels and configured to route wiring from the electrical subsystem to the toilet cabin;
- and
- a mounting interface on the outer surface of the structural frame configured to secure the technical room to the trailer frame.
