  • Patent number: 7225056
    Abstract: In household appliances with a safety hose, the stop valve and the control valve are hydraulically connected in series. It is thus impossible, or very difficult, for the user to detect when one of the valves is operating erroneously and not closing completely. The functioning of the control valve and of the stop valve is checked each time the household appliance is used. For this purpose, the valves and are alternately opened and closed in a selected phase during operation, or are opened and closed one after the other. The change over time in the measured values is recorded and evaluated in a suitable manner at a pressure sensor and/or at a throughflow meter. On account of the multiple use of the measuring sensors that are present, the cost of implementing the method is restricted to expanding the control system software.
