Description
【発明の詳細な説明】 本発明は高周波加熱装置に関するものである。[Detailed description of the invention] The present invention relates to a high frequency heating device.
従来高周波加熱装置の均一加熱手段として、高周波を攪

熱物を回転移動するターンテーブル等が知られている。Conventionally, as a uniform heating means of a high-frequency heating device, a stirrer for stirring high-frequency waves, a rotating antenna for radiating high-frequency waves, a turntable for rotationally moving an object to be heated, and the like have been known.
しかし、それらの手段を用いても十分な均一加熱性能を
得ることは難しい。However, even if these means are used, it is difficult to obtain sufficient uniform heating performance.

It is a single frequency oscillator. In order to radiate high frequency energy into the heating chamber 5, reference numeral 2 denotes a rotary antenna A, which is rotatably supported by a metal high frequency coupling rod 4 and a dielectric drive shaft 5, and is a waveguide that supplies VC high frequency energy. It is.

室７を設け、その中に回転アンテナ６を設けると。7, the height 11 of the upper wall of the heating chamber 6 itself is about 20 to 50 mm, and the diameter is 1 times the free space wave λ0 of the frequency used. It is a cylindrical antenna storage chamber formed to easily generate a peak value at the center position, and is sufficiently thick compared to λoiC, so that it can accommodate a practical rotating antenna 6 that radiates a wide range of energy.
a is a direct (f=, I) circular high-frequency radiation 11 at the bottom of the antenna storage chamber 7; Reference numeral 8 denotes a turntable on which the object to be heated 9 is placed and rotated.Next, the functions and effects of the above configuration will be explained below. If the rotating antenna 6 or the turntable 8 is used alone or in combination, the central part of the object to be heated 9 tends to be delayed, but as in this embodiment, there is a certain dimension (-2-± publication). An antenna storage chamber 7 having a diameter of λ0 is provided, and a rotating antenna 6 is provided therein.

くて済み経済的である。It has been experimentally confirmed that the entire object to be heated 9 is heated almost uniformly, and the central part can be heated more quickly, resulting in faster overall finishing time. In particular, the antenna storage chamber 7 is a heating chamber. 3. Because the upper wall itself is squeezed and formed, 1. For example, another cylindrical antenna storage chamber 7
Compared to spot welding on the upper wall of the entire heating chamber 3, there are no extra spot joints, so there is less power loss due to high frequency current flowing through each metal wall surface, improving heating efficiency, and making work easier. It has good properties and is economical as it requires less metal plate material.

熱装置を提供することができＺ）。As described above, according to the present invention, a cylindrical antenna chamber having a diameter of a specific size as described in ``2'' is formed by squeezing the upper wall of the heating chamber itself, and a V-shaped rotary antenna is provided therein. Since it is used in combination with a table, it is possible to provide an economical high-frequency heating device that has good uniform heating performance, good heating efficiency, and is economical.
