Self-cleaning sanitation module incorporating a tilting back

Self-cleaning sanitation module comprising a closed enclosure, a vertical wall in said enclosure dividing it into a user area and a technical area, an opening in said wall, an open-top toilet pan having a top surface lying in a first plane and disposed along said vertical wall and adapted to rotate about an axis parallel to said vertical wall between a use position in which said top surface is rotated through said opening and into said user area such that said top surface lies in a plane substantially normal with respect to said vertical wall and a cleaning position in which said top surface is rotated through said opening and into said technical area such that said top surface is substantially vertical and faces toward said technical area, a back plate having upper, lower and side edges and being movably mounted in said enclosure between a use position in which it covers said opening above said toilet pan when said pan is in its use position and a cleaning position in which it is vertically above said pan and coplanar with said top surface of said pan when said pan is in said cleaning position, and cleaning means in said enclosure for cleaning said pan and said back plate when in their cleaning position, said back plate being adapted to rotate about horizontal axes parallel to said vertical wall on moving from its use position to its cleaning position, said back plate being articulated so that it performs a first rotation from its use position about a first horizontal axis located at the rear of said back plate when in its use position, said first horizontal axis being in a substantially median plane of said back plane and at a distance from the latter substantially equal to half the height of said back plate so that said lower edge of said back plate remains near said top surface of said pan during rotation of said pan from its use position toward its cleaning position, said back plate then proceeding to an intermediate position in which said back plate is substantially horizontal with respect to said vertical wall, and said back plate performing a second rotation about a second horizontal axis near its upper edge from said intermediate position to its cleaning position.
