Operation of a domestic microwave appliance as a function of a microwave generator temperature

A household microwave appliance, comprising:

• a cooking chamber;
• a microwave generator for routing microwaves to the cooking chamber;
• a temperature-determining apparatus for determining a temperature of the microwave generator;
• a microwave distribution device designed to change a field distribution in the cooking chamber during a microwave treatment operation;
• and
• a control device designed to control the microwave treatment operation as a function of the temperature of the microwave generator effected by a change in the field distribution,
• wherein the microwave distribution device is designed to change the field distribution by changing a setting value of an operating parameter of the microwave distribution device, and
• the control device is designed to determine from the change in temperature an extent of a change in a portion of a microwave power radiated into the cooking chamber which portion is reflected from the cooking chamber back to the microwave generator.

• and
• a control device designed to control the microwave treatment operation as a function of the temperature of the microwave generator effected by a change in the field distribution,
• wherein the control device is designed
• to record a temperature curve during the microwave treatment operation,
• to determine curve gradients before and after a switchover time, at which the field distribution has been changed in the cooking chamber, and
• to determine from the change in the curve gradients whether the back-reflected portion of the microwave power is higher for the field distribution before the switchover time or for the field distribution after the switchover time.
