摘要： A steam generating apparatus includes a body for receiving water to be heated and has a first portion including a first metal, and a heating device having a second portion including a second metal. The heating device includes a heating plate connected with the body by forming an intermetallic layer between the first and second portions. A temperature sensor measures temperature indicative of pressure inside the body and thermally contacts the heating device outside the body. A method of controlling the pressure of steam in the steam generating apparatus includes setting the target water temperature for a first time period to a first set temperature; setting the target water temperature for a second time period to a second set temperature higher than the first set temperature; and setting the target water temperature for a third time period to a third set temperature lower than the second set temperature.

摘要： The present invention relates to a method of determining a liquid level in a boiler (12) of an apparatus (10) having a temperature sensor (24) for sensing a temperature (T) which is indicative of a temperature of the liquid inside the boiler (12), comprising the steps of: inducing a temporary deflection of the temperature (T) sensed by the temperature sensor (24); determining an evaluation temperature (T ev ) sensed by the temperature sensor (24) after inducing the deflection; and determining the liquid level from at least the evaluation temperature (T ev ). Advantageously, the invention provides that the evaluation temperature (T ev ) is determined by monitoring the deflection and by defining an extreme value (T max, T min ) of the deflection as the evaluation temperature (T ev ). Further, the present invention relates to an steam generating apparatus adapted for executing such a method, a domestic appliance having such a steam generating apparatus.
