Abstract
Abstract A system is disclosed for automatically cleaning an enclosure such as a bathroom or the like. Sufficient spray nozzles are disposed about the enclosure to ensure adequate spray coverage of same and are connected through the enclosure walls with a fluid supply line such as a water line. A cleaning solution supply, sanitizing solution supply or the like is associated with the fluid supply line to be discharged therein at the appropriate time. Likewise, a dryer means such as an air blower is disposed appropriately within the enclosure so as to assist in removing the fluid therefrom after cleaning. Further, a control means is provided that operatively associates all of the aforementioned elements into a cleaning cycle, whereby, upon actuation of the control means, particular valves are actuated to permit the flow of fluid to the spray nozzles for washing down the walls, floor and the like of the enclosure. At the appropriate time in the cycle, cleaning solution, sanitizers, or the like are discharged into the fluid supply line and carried with the fluid into the confines of the enclosure. Subsequent to cleaning, a rinse cycle is optionally included. After all washing steps are completed, the drying means is actuated as a part of the clean cycle to assist in removal of the cleaning solution from within the enclosure. Structures having the above described system incorporated therein are also claimed.
