Abstract

Die Erfindung betrifft Gargerät (10) mit einem Garraum (12), einem Dampfgenerator (14) und einer Steuerung (16), wobei die Steuerung (16) einen Schwellwertregler (22) sowie einen stetigen Regler (24) aufweist. Die Erfindung betrifft auch ein Verfahren zur Regelung eines Dampfgenerators (14) für ein Gargerät (10), das dadurch gekennzeichnet, dass der Dampfgenerator (14) in einer Annäherungsphase, in der sich ein zu regelnder Istwert in einem Garraum (12) des Gargeräts (10) stark von einem Sollwert unterscheidet, von einem Schwellwertregler (22) gesteuert wird und in einer sich anschließenden Haltephase, in welcher der Istwert sich in der Nähe des Sollwerts befindet, von einem stetigen Regler (24) gesteuert wird.

The invention relates to cooking appliance (10) having a cooking chamber (12), a steam generator (14) and a controller (16), wherein the controller (16) has a threshold controller (22) and a continuous controller (24). The invention also relates to a method for controlling a steam generator (14) for a cooking appliance (10), which is characterized in that the steam generator (14) in an approach phase, in which an actual value to be regulated in a cooking chamber (12) of the cooking appliance ( 10) is greatly different from a desired value, is controlled by a threshold value controller (22) and is controlled by a continuous controller (24) in a subsequent holding phase in which the actual value is close to the nominal value.
