Abstract: A device for cleaning the toilet seat of a toilet bowl, in which the toilet seat 22 is brought into vertical position in a tank 14 by a translational movement of transport means driven by vertical endless screws. A trap door 18 is thus controlled by a horizontal shaft and link rods 60a, 60b which opened during the entry and exit movements of the seat. A cleaning arm 66 is connected to a cleaning water intake, and means are provided to cause hot drying air to circulate in the tank. A control unit containing a cleaning water tank, a hot-air generator, and a time-delay control unit can be triggered to perform a complete cleaning cycle, and can be located as desired. The device is for toilets in private or public use.
