electric household appliance and cartridge with a means of preventing scale, and process for preventing scale in an electric household appliance

摘要

Household appliance, in contact with an aqueous medium, having a water circuit at least partially traversing a compartment containing a disincrustant agent. The disincrustant agent is obtained by cross-linking or hardening of an organosilicic system having a disincrustant action. The system includes: an ingredient consisting of a polyorganosiloxane composition, hardenable into a siicone elastomer at room temperature or under the effect of a temperature greater than room temperature, at least partially cross-linked or not, permeable to water vapor, and an ingredient, which is hydrophilic and osmotically active, consisting of an active disincrustant material taken alone or in association with a hydrophilic auxiliary agent, dispersed in a homogenous manner within the silicone ingredient, the active disincrustant material being liberated over time, in an aqueous medium, out of the silicone ingredient hardened into elastomer, at a substantially constant rate when the temperature in the compartment is substantially constant.
