主权项

1. A bathing enclosure for enclosing a person while bathing, comprising:
a) a plurality of vertical walls forming a perimeter of said bathing enclosure; b) a floor having a drain for draining fluid from said bathing enclosure; c) a drain valve within said drain for controlling fluid flow through said drain; d) a reservoir above said drain valve for collecting fluid when said drain valve is closed; e) a pump in fluid communication with said reservoir; f) at least one spray nozzle in fluid communication with said pump; g) a source of liquid cleaner in fluid communication with said bathing enclosure; h) a liquid cleaner valve for controlling fluid flow from said source of liquid cleaner to said bathing enclosure; i) a liquid cleaner recycle valve for controlling fluid flow from said reservoir to said source of liquid cleaner; and j) a controller in communication with said drain valve, said pump, said liquid cleaner valve, and said liquid cleaner recycle valve; k) wherein said controller is operable to open said liquid cleaner valve such that said source of liquid cleaner dispenses liquid cleaner into said bathing enclosure; l) wherein said controller is further operable to close said drain valve, wherein said reservoir is operable to collect said liquid cleaner from said bathing enclosure when said drain valve is closed; m) wherein said controller is further operable to activate said pump to pump said liquid cleaner from said reservoir, through said pump, and through said at least one spray nozzle onto said vertical walls and said floor of said bathing enclosure; n) wherein said controller is further operable to cycle said liquid cleaner from said reservoir, through said pump, through said at least one spray nozzle, and onto said vertical walls and said floor of said bathing enclosure for a predetermined period of time to clean said vertical walls and said floor; o) wherein said controller is further operable to activate said pump to pump said liquid cleaner from said reservoir, through said pump, and into said source of liquid cleaner to be stored for later use.
