1. A cooking appliance apparatus, in particular an oven apparatus, comprising:
a muffle defining a cooking chamber;
a resistance heating element configured to heat the cooking chamber;
a switching unit configured to connect the resistance heating element to a first supply voltage in a first operating state wherein the resistance heating element is connected to a first phase of a power supply network, and to a second supply voltage in a second operating state, with the second supply voltage being different from the first supply voltage;
a high-frequency power supply unit configured to receive the first supply voltage and configured to supply the second supply voltage in the second operating state wherein the resistance heating element is connected to the high-frequency power supply unit, the first supply voltage being connected to the resistance heating element without passing through the high-frequency power supply unit by being connected to the first phase of the power supply network; and
an induction heating element connected to the high-frequency power supply unit in an operating state,
the switching unit is configured to connect the resistance heating element to a third supply voltage in a third operating state, and
the third supply voltage is a further network voltage supplied from a second phase of the power supply network.
