A cooking method is used to prepare a food in the cooking chamber of a cooking device. The cooking chamber includes a first opening, a second opening and a closure for closing the second opening. Furthermore, the cooking device includes a temperature sensor arranged outside the cooking chamber for detecting gas volumes escaping from the cooking chamber through the first opening. During the cooking process, the closure is moved from a first position to a second position. After leaving the first position, a measurement is performed by means of the temperature sensor.

In a method for operating a household steam treatment appliance which includes an evaporator with a heatable water holding chamber and a fill level sensor with at least two measurement electrodes, which are disposed over one another at a distance from each other in the heatable water holding chamber, a water detection measured value provided for indicating wetting of the at least two measurement electrodes with water introduced into the water holding chamber is adapted in an adaptation process to an electrical conductivity of the water in the water holding chamber.

A method for calibrating an oxygen sensor of a household appliance includes a calibration process which is automatically started when at least one status parameter of the household appliance has at least reached a predetermined threshold value. The household appliance can be a steam cooking appliance, and the oxygen sensor can be a lambda probe.

A steam generator is provided. The steam generator may include a steam chamber, a steam heater to supply heat into the steam chamber, a water supply, through which water to generate steam may be supplied into the steam chamber, one or more interference members disposed in the steam chamber to interfere with a flow of the water introduced through the water supply, and at least one discharge to discharge the steam generated in the steam chamber. The one or more interference members may be disposed under the at least one discharge and above the water supply.

An apparatus comprises at least two cooking devices, a control unit, an input device and an output device. The control unit is adapted to determine if at least two of the foodstuffs to be cooked can be cooked in one of the cooking devices in an at least partly concurrent manner. Depending thereon, the control unit allocates the foodstuffs to be cooked to the cooking devices and outputs, via the output device, which of the foodstuffs can be cooked in which cooking device or in which cooking devices.

A food heating device includes a placement unit and a heating unit. The placement unit includes a housing and a placement board, wherein the placement board is disposed in the housing and is for placing a food item. The heating unit includes a water injection element and a microwave element, wherein the water injection element connects to the housing and is communication with an internal space of the housing, and the microwave element connects to the housing. The microwave element is for heating by microwave the water injected into the internal space of the housing through the water injection element and producing steam therefrom.
