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.

In a cleaning device for the seat of a toilet bowl comprising
- a chamber extending vertically in a back region of the toilet bowl, said chamber having a trap door with an inside face,
- transport means for bringing the seat from a use position, in which it extends horizontally over the bowl, to a cleaning position, in which it extends vertically within said chamber, and for controlling simultaneously opening and closing of said trap door,
- cleaning means provided in said chamber for spraying cleaning water on the seat when the seat is in said cleaning position, and
- drying means for circulating air in said chamber to dry the seat while in said cleaning position,
- the improvements comprising:

- said transport means of said seat in said chamber extending above and behind said seat, and including a motorized unit having bidirectional vertical movement, a horizontal shaft and two link rods, said single seat being connected at said rear end thereof to said motorized unit,
- each said link rod having a first end mounted on said trap door to rotate in correspondence with said bidirectional vertical movement of said motorized unit to open and close said trap door;
- said transport means further comprising two vertical lead screws and an electric motor;
- said horizontal shaft having two ends, each said end of said horizontal shaft having a respective tapped sleeve which circulates on a respective one of said said two vertical lead screws, said two vertical lead screws being rotated in synchronism by said electric motor to provide said bidirectional vertical movement to said horizontal shaft;
- said motorized unit being mounted to rotate around said horizontal shaft during said bidirectional vertical movement;
- and
