Abstract: A sanitary device with a mechanical single hole (15) mixer (5) for horizontal top (13), said mixer (5) including an axially extended mixer body (17), a mixer cartridge (19), a housing (25) for the mixer cartridge (19) formed within the body (17) of the mixer (5), a water delivery flue pipe (33) and a lever (63) for controling capacity and temperature of the water, characterised in that said mixer body (17) is placed through said hole (15) in said horizontal top (13) and said mixer cartridge (19) is placed at least partially below said top (13) of the mixer (5).

Abstract: A hot and cold water mixer comprising: a mixer body defining a hot water inlet conduit and a cold water inlet conduit opening towards a mixing chamber communicating with a water delivery orifice; the mixing chamber has therein a mixing unit operably driven, by a control handle or knob, between a closed position, a hot water or cold water open position, and a mixing position. The mixing unit comprises a stationary disc of ceramic material having first and second apertures communicating with said hot and cold water inlet conduits, and a movable block of ceramic material having a flat face sealingly sliding against a flat face of said disc; said block has a cavity opening to said flat face and respectively to the side surface to define a water passage from said inlet conduits to the mixing chamber, the width of the block cavity being larger than the distance or spacing between the apertures in said ceramic disc in order to communicate with either or partially with both the apertures in said disc.
