This cleaning apparatus has for this purpose a cover which overlaps the spray nozzles serving for cleaning the bowl and seat. In the flushing position, the cover and the bowl together bound a cleaning space which is sealed fluid-tight from the interior of the housing. During the cleaning process, even contaminants adhering stubbornly to seat surface or inner wall of the bowl are removed by the pressurized water and washed in the direction of the feces drain. After the cleaning with pressurized water, the bowl and the seat are dried with cold or hot air, for which purpose the cleaning apparatus is additionally provided with a fan.

Abstract: An assembled toilet bowl mainly includes a seat section, a base and a valve cover set. When activating a flushing control member, the valve cover is opened. The water from the water source will flow through a water incoming passage of the seat section and a bowl-shaped space. Then the water will horizontally flow through a valve port and then flow through a draining passage of the base and downward flow out. Reversely, when the flushing control member is not activated, the valve cover is closed. Under such circumstance, the water of the water source will not flow out and the valve cover will block the valve port to isolate the draining passage. Therefore, the toilet bowl can save more water, can be fixed on a wall, can be easily assembled, and can be easily cleaned.
