Embodiment Construction

[0044] The domestic appliance in the form of a boiler 1 has a cooking chamber 2 which can be acted upon with steam, an oxygen sensor in the form of a lambda probe 3 and a data processing unit 4 . Data processing unit 4 is designed to determine the water content in cooking chamber 2 on the basis of the measured values ​​of lambda probe 3 . Furthermore, the data processing unit 4 is set up to carry out the method. The data processing unit 4 can be a central control unit for operating the cooking appliance 1 .

[0045] For the method, the data processing unit 4 checks in a first step S1 whether the state parameter in the form of the duration Z-Z0 since the time Z0 of the last calibration is greater than the specified duration The time constitutes the threshold in the form of Zg. In other words, it is checked in step S1 whether the duration Zg has elapsed since the last calibration carried out at time Z0 until the current time Z. Zg can be 30 hours, for example. If this is not...

Abstract

The invention relates to a method (S1-S7) for calibrating an oxygen sensor (3) of a domestic appliance (1), in which a calibration process (S4-S7) is automatically started when at least one status parameter (Z, t, T) of the domestic appliance (1) has at least reached (S1-S3) a predetermined threshold value (Zg, tg, Tg). The invention is in particular advantageously applicable to ovens having a steam cooking function.

Description

technical field [0001] The invention relates to a method for calibrating an oxygen sensor of a domestic appliance. The invention can be applied particularly advantageously to cooking appliances, such as ovens with a steaming function or separate steamers. Background technique [0002] DE 10 2010 054 607 B3 relates to a method for operating a cooking appliance, the method having the following steps: detecting the oxygen partial pressure by means of a lambda probe; determining the actual ambient pressure on the basis of the detected oxygen partial pressure and The cooking appliance is calibrated on the basis of the actual ambient pressure. "Calibrating" here means identifying the actual ambient pressure of the cooking appliance and adapting the operating process to the actual ambient pressure. A prerequisite for this is that the oxygen partial pressure determined by means of the lambda probe can be correctly correlated to the gas pressure. In order to reduce the influence o...
