Definitions

  • the US-A 3 494 722 discloses a method and apparatus for sterilizing by means of microwave radiation.
  • the microwave radiation may in this case have a wavelength in the range between 0.9 and 17 GHz.
  • a wavelength between 2.36 and 2.9 GHz or the usual operating frequency of 2.45 GHz is preferred.
  • an apparatus for treating substances having electromagnetic radio frequency energy is known.
  • magnetrons with an operating frequency of about 100 MHz to 10 GHz are used, which are supplied from power supplies with low ripple.
  • a microwave device, ie a magnetron with an operating frequency of 2.45 GHz is used.
  • the respective magnetron has a certain operating frequency in order to achieve the respectively desired heat output.
  • the microwave oven system according to the invention thus has, for example, the advantage that in an existing microwave oven with magnetrons, for example, the operating frequency 2.45 GHz these magnetrons can be replaced by magnetrons operating frequency 5.8 GHz.
  • the user of an existing microwave oven does not have to procure a new microwave oven if he needs a different heat output, but he only needs to replace the existing magnetrons with magnetrons of the appropriate operating frequency.
  • a very significant advantage is also that the power supply of the existing microwave oven does not need to be replaced, but that the existing power supply is still used unchanged or only a few components for adaptation are required.
  • the at least one magnetron in the corresponding microwave oven directly, i. is provided without further microwave coupling device. If the at least one magnetron combined with a coupling device, then it has proved in the microwave oven according to the invention as appropriate when the magnetrons of the various operating frequencies are combined with respective microwave input devices. This means that when replacing a unit consisting of a magnetron of a certain operating frequency and the associated microwave coupling device, this unit can be removed from the microwave oven and another unit from another magnetron with associated microwave coupling device can be mounted on the microwave oven. This is easy and time saving possible.
  • the magnetron 12 has a certain operating frequency.
  • magnetrons 12 of different operating frequencies each have the same mechanical mounting dimensions. This is indicated in the figure by the double arrow 18. Characterized in that the magnetrons 12 of the different operating frequencies are formed with the same mechanical mounting dimensions 18, it is easy and time-saving possible to replace a magnetron 12 of a certain operating frequency as desired by a magnetron 12 of a different operating frequency.
  • the magnetrons 12 of the different operating frequencies each have the same electrical operating parameters as anode voltage, heating voltage and heating current, so that the magnetrons 12 of the different operating frequencies can be operated with the same power supply 14, or only minor changes are required, which can be compensated with a few components are.
