Abstract

Abstract A laundry washing machine comprises a dispenser of washing agents ( 10 ) having at least a movable body ( 26 A, 26 B, 40 ) defining a compartment for containing a dose of a respective washing agent. The movable body ( 26 A, 26 B, 40 ) is mounted in a housing ( 11 ) in such a way as to be able to assume a first position, for the manual admission of a washing agent into the compartment through a loading mouth ( 27, 41 ), and a second position, for withdrawing the washing agent from the compartment by means of a flow of liquid (IN). The movable body ( 26 A, 26 B, 40 ) is pivotally supported in the respective housing ( 11 ) to move angularly from said first to said second position and vice versa, around an axis (X) that is substantially perpendicular or otherwise transverse relative to the axis (Y) of the loading mouth ( 27, 41 ) of the body ( 10 ). Preferably, the movement of the body ( 26 A, 26 B, 40 ) from the first to the second position is obtained by means of the aforesaid flow of liquid (IN).
