  • Patent number: 5638622
    Abstract: A steam iron with an electric pump for conveying water from a water tank to individual water consumers and control electronics, which control the pump as a function of actuated cut-off valves. The control electronics recognize and control the different operating modes associated with the respective water consumers as a function of pressure changes in the pressure control circuit. The operating duration of the pump is restricted to a maximum time in accordance with the respective operating mode.

  • Patent number: 5438914
    Abstract: An electric circuit operating on a single-phase power supply system for controlling the heat output of at least two heating resistances which are electrically connected in parallel and are installed in electric household appliances, particularly toasters, wherein the control is being effected in compliance with flicker standards and without feeding interference back into the power supply system. A switch is connected in series with each heating resistance, wherein the switches are activated by an electronic energizing arrangement. During a heating phase, the switches of the circuit are repetitively asymmetrically cycled in such a way that always only one switch is closed and all other switches are open, wherein the switch which is closed at a given time exclusively permits the through-passage of full waves from the power supply system.
