A modular vacuum toilet, and a method of servicing such a toilet, are disclosed. The toilet is used with a vacuum toilet system having a sewer line placeable under partial vacuum pressure and a source of rinse fluid. The modular vacuum toilet comprises a frame and a removable bowl engaging and supported be the frame, the bowl defining an outlet and having a rinse fluid dispenser associated therewith. The modular vacuum toilet also has a valve set module. The valve set module includes a discharge valve having an inlet in fluid communication with the bowl outlet, an outlet in fluid communication with the sewer line, and a movable discharge valve member disposed between the discharge valve inlet and outlet. A rinse fluid valve is also incorporated into the valve set module and has an inlet in fluid communication with the source of rinse fluid, an outlet in fluid communication with the rinse fluid dispenser, and a movable rinse fluid valve member disposed between the rinse fluid valve inlet and outlet. The valve set module further includes a flush control unit having a circuit board operably connected to the discharge valve and rinse fluid valve for controlling actuation of the discharge valve member and rinse fluid valve member.
A modular vacuum toilet for use in a vacuum toilet system having a sewer line placeable under partial vacuum pressure and a source of rinse fluid, the modular vacuum toilet comprising:
A method of servicing a vacuum toilet having a waste receptacle for receiving waste defining an outlet and having a rinse fluid dispenser associated therewith, a stationary frame support having a top with an opening therethrough, the waste receptacle including a sidewall sized for insertion into the opening and having an out-turned flange supported by the top of the support structure, a discharge valve having an inlet in fluid communication with the receptacle outlet, an outlet in fluid communication with a sewer line placeable under partial vacuum pressure, and a moveable discharge valve member disposed between the discharge valve inlet and the discharge valve outlet, a rinse fluid valve having an inlet in fluid communication with a source of rinse fluid, an outlet in fluid communication with the rinse fluid dispenser, and a moveable rinse fluid valve member disposed between the rinse fluid valve inlet and the rinse fluid valve outlet, and a flush control unit adapted to control actuation of the discharge valve member and rinse fluid valve member, in which at least one of the discharge valve, rinse fluid valve, flush control unit, and waste receptacle is a line replaceable unit, the method comprising:
