Definitions
- the invention relates to a microwave oven or a combination cooker with microwave operation.
- microwave ovens In microwave ovens (microwave ovens) is in one Cooking space Cooking material, especially food, with microwaves cooked.
- combination cooking appliances are in addition to the microwave operation also other modes of cooking food, e.g. Grill operation, top and / or bottom heat, recirculation mode, provided that operated individually or jointly can be.
- Grill operation top and / or bottom heat, recirculation mode, provided that operated individually or jointly can be.
- recirculation mode provided that operated individually or jointly can be.
- Microwave oven both the pure microwave appliances as well as the combination devices to understand.
- microwave ovens are usually the one of Microwave generator (magnetron) generate microwaves over a waveguide passed into a cooking chamber. Is located in the cooking chamber a food (for example, food or drinks), so the microwaves penetrate at least partially the food to be cooked. Microwaves are absorbed by water and give off their energy. Because food always contains water contains or if the food to be cooked is water itself, the food to be cooked is absorbed by the microwave energy absorbed by the food heated.
- Microwave generator magnet
- microwave energy is in this case of device components in or on the cooking chamber at least partially be absorbed.
