Abstract
Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a tank, a flush valve, and a rim in fluid communication with the bowl through a rim flow path from an outlet of the flush valve to at least one rim outlet port. The flush valve is configured to operate in a flush actuation mode wherein the flush valve is able to provide flush water flow sufficient for the toilet assembly to initiate a flush siphon or provide a wash down flush and to operate in a cleaning actuation mode wherein the flush valve is only partially opened to allow for introduction of a cleaning agent and flush water mixture to the bowl that is insufficient to initiate a siphon but sufficient for cleaning the bowl. The cleaning system includes a reservoir for a liquid cleaning agent, a housing for the reservoir, a supply conduit for receiving fluid from within the reservoir and delivering it to a flush valve, a flow control device capable of controlling flow of cleaning agent and a control system activatable by an actuator feature to initiate a clean cycle by operating the flow control device …
