External thermostatic mixer, particularly for hygienic-sanitary components, with high safety against the danger of contact burns

摘要

An external thermostatic mixer for hygienic-sanitary components with high safety against danger of contact bums, comprising a mixer body (2, 2a) with a mixing chamber (3, 3a) that accommodates a thermostatic mixing cartridge (4, 4a) and has at least one first inlet (5, 5a) for cold water, at least one second inlet (7, 7a) for hot water, and at least one outlet (9, 9a) for mixed water. At least the mixed water delivery duct (10, 10a) extends within a protective body (11, 11a) arranged inside the mixer body (2, 2a) and spaced, over at least part of its extension, from the internal walls of the mixer body (2, 2a). Between the mixer body (2, 2a) and the protective body (11, 11a) a space (12, 12a) is defined separated hermetically from the hot water supply port (8, 8a) and from the mixed water outlet (9, 9a).
