Abstract
In a method for detecting a standstill of a rotatable microwave distribution apparatus of a household microwave appliance, while microwaves are being supplied into a cooking compartment of the household microwave appliance, a microwave leakage radiation for angle-dependent recurring fluctuations is monitored and an action in the absence of such fluctuations being detected.
Claims18
A method for detecting a standstill of a rotatable microwave distribution apparatus of a household microwave appliance, said method comprising:
- while microwaves are being supplied into a cooking compartment of the household microwave appliance, monitoring a microwave leakage radiation for angle-dependent recurring fluctuations;
- and
- triggering an action in the absence of such fluctuations being detected.
A household microwave appliance, comprising:
- a cooking compartment;
- a microwave generator generating microwaves for supply into the cooking compartment;
- a rotatable microwave distribution apparatus configured to vary a field distribution of microwaves that are supplied into the cooking compartment;
- a leakage radiation measuring apparatus configured to measure a microwave leakage radiation;
- and
- a data processing apparatus connected to the leakage radiation measuring apparatus, said data processing apparatus configured to monitor a microwave leakage radiation for angle-dependent recurring fluctuations while microwaves are being supplied into the cooking compartment and to trigger an action in the absence of such fluctuations being detected.
