Abstract: A disperser of washing agents is described, for a household washing machine, in particular a dishwasher, said dispenser (10) comprising a tank (12) for containing a liquid washing agent to which a visual control device (17-18) is associated, of the level of said liquid washing agent, said control device comprising a passage (18), placed between said tank (12) and the external part of the body (11) of the dispenser (10), and an element in a substantially transparent material (17) inserted in said passage (18), a first portion (22) of said transparent element (17) being at least partially visible from the outside of said body (11) and a second portion (17B) of said transparent element (17) being inserted in said tank (12), where at the free end of said second portion (17B) a series of projections (20) is defined, being placed at different levels of height.

Abstract: A Thermal actuation device has at least a heat expandable or deformable material, a heater, a power supply for the heating, a thruster capable of movement following expansion or distortion of a material, so as to perform a substantially predetermined stroke having a length from a first to a second position, at least an actuation element linearly following the action of the thruster so as to move with respect to a fixed structure from a first to a second position, and a resilient device able to return the thruster and/or actuation element respective first positions. A motion multiplyer actuated by the thrusting means is further provided for obtaining a stroke of the actuation element longer than the stroke of the thruster.
