Patent ID: 8256137

Claim:
Method of determining clogging of the lint filter ( 23 ) of the steam generator ( 17 ) of a home laundry drier ( 1 ), wherein said steam generator ( 17 ) comprises an electric boiler ( 18 ) designed to receive a given quantity of water and convert said water into low-pressure steam, a steam exhaust manifold ( 19 ) connecting the outlet of said electric boiler ( 18 ) to the laundry container ( 3 , 5 ) of said home laundry drier ( 1 ), and a water reservoir ( 20 ) located above and communicating with said electric boiler ( 18 ); the home laundry drier ( 1 ) also comprising a hot-air generator ( 7 ) for circulating a stream of hot air inside the laundry container ( 3 , 5 ), and a water drain circuit ( 13 ) which draws distilled water from the water canister ( 12 ) of the condenser ( 10 ) of said hot-air generator ( 7 ), and feeds said water at least partially into said water reservoir ( 20 ); the lint filter ( 23 ) of said steam generator ( 17 ) being interposed between said water drain circuit ( 13 ) and said water reservoir ( 20 ), and the method being characterized by comprising the steps of: determining whether the water reservoir ( 20 ) is in a given low-water-level condition at the start of the user-selected drying cycle; determining whether the water reservoir ( 20 ) is in said low-water-level condition at the end of the user-selected drying cycle; and determining clogging of the lint filter ( 23 ) of said steam generator ( 17 ) when the user-selected drying cycle does not include activation of said steam generator ( 17 ), and said water reservoir ( 20 ) remains in the low-water-level condition at both the start and end of the user-selected drying cycle.
