Description

Microwave oven

Technical field

The technical solution relates to the placement of a waveguide or an RF energy antenna in a device in which a solid material, such as wood containing moisture, can eventually be dried.

BACKGROUND OF THE INVENTION

Prior art devices operating on the principle of microwave drying by means of high-frequency energy have a mangetron generator located on the side, that is, from the side and the waveguide, or the antenna is guided under the drier tub.

The essence of the technical solution

The device is made of metal tub with lid in dimensions suitable for storing the specified material, generator and control system. Thus, it is possible to assemble microwave ovens of different contents. The generator is located under the tub and flows into a waveguide (antenna), which is located at the bottom of the dryer. The waveguide (antenna) radiates heat through the slots of the waveguide (antenna) made of teflon, a material that, by appropriate placement of the slots, radiates heat to the drying chamber. The device uses high-frequency energy for heating and subsequent drying or drying. for steaming materials containing moisture. The metal tub defines the space in which the material is inserted. The radio frequency produced by the generator is fed into the space thus defined by a waveguide (antenna) located at the bottom of the bath. The magnet of the generator is positioned centrally relative to the waveguide (antenna), which, combined with the waveguide (antenna) location, achieves higher power and better spatial arrangement of heat radiation * throughout the device.

- In case of higher power requirements, a larger number of j generators can be fitted with waveguides (antennas) placed parallel to each other. In both cases, the waveguide (antenna) is in the drying chamber.

Examples

Example 1

Microwave oven in a metal tub with lid, where the magnetron generator is located in the center of the waveguide (antenna). The waveguide (antenna) is located in the drying chamber and the heat is radiated by the Teflon slots into the drying chamber. The dryer constructed in this way has a working space up to the capacity of the generator. In case of larger working space of the dryer, the generators according to example 2 are installed.

Example 2

With an increased (larger) working space of the microwave oven, a plurality of generators with waveguides (antennas) placed parallel to each other in the oven space are mounted in the apparatus.
