Abstract:
Household appliance, in contact with an aqueous medium, comprising water circuit (2) at least partially traversing a compartment (1) containing a disincrustant agent, characterized in that the disincrustant agent is obtained by cross-linking or hardening of an organosilicic system having a disincrustant action comprising:an ingredient (A) consisting of a polyorganosiloxane composition, hardenable into a silicone elastomer at room temperature (23.degree. C.) or under the effect of a temperature greater than room temperature, at least partially cross-linked or not, permeable to water vapor, andan ingredient (B), which is hydrophilic and osmotically active, consisting of an active disincrustant material (B1) taken alone or in association with a hydrophilic auxiliary agent (B2), dispersed in a homogenous manner within the silicone ingredient (A), with the particularly according to which the active disincrustant material is liberated over time, in an aqueous medium, out of the silicone ingredient (A) hardened into elastomer, at a substantially constant rate when the temperature in the compartment is substantially constant.
