Description
【考案の詳細な説明】
本考案は−っの加熱室に２個の回転アンテナを設け、そ
の各々から電磁波を放射するようにした高周波加熱装置
に関するものである。[Detailed Description of the Invention] The present invention relates to a high-frequency heating device in which two rotating antennas are provided in a heating chamber, and electromagnetic waves are radiated from each of the rotating antennas.
従来のこの種のものの一例を第１図で説明すれば、ｌａ
、ｌｂ、はマグネトロンで、それにより発生した電磁波
は導波管２ａ、２ｂを通して、加熱室３の上面及び下面
に設けられた電磁波放射口４ａ、４ｂから加熱室内に放
射される。An example of a conventional device of this type is shown in Fig. 1.
, lb are magnetrons, and the electromagnetic waves generated thereby are radiated into the heating chamber from electromagnetic wave radiation ports 4a and 4b provided on the upper and lower surfaces of the heating chamber 3 through waveguides 2a and 2b.
その場合の電磁波の伝送は、放射口４ａ、４ｂを貫通す
る回転軸５ａ、５ｂにより、又加熱室３内への放射は回
転軸５ａ、５ｂに結合した金属凸起平板、いわゆる回転
アンテナ６ａ、６ｂによって行なわれる。In this case, the electromagnetic waves are transmitted by the rotating shafts 5a, 5b passing through the radiation ports 4a, 4b, and the radiation into the heating chamber 3 is transmitted by a metal convex plate, a so-called rotating antenna 6a, connected to the rotating shafts 5a, 5b. 6b.
回転アンテナはモーター等によって回転させられるので
電磁波を周囲に均等に分散させ、その結果高均一の加熱
が可能となる。Since the rotating antenna is rotated by a motor or the like, electromagnetic waves are evenly distributed around the antenna, and as a result, highly uniform heating is possible.
しかし、出力切換のために例えば下面放射のみ使用し・
上面放射を停止させて使用した場合、被加熱物は回転ア
ンテナ６ｂからの一次放射Ａと、加熱室壁面に反射して
後の二次放射Ｂとで加熱されるが、回転アンテナ６ａは
停止しているため二次放射Ｂの攪拌はなく、加熱むらの
原因となる。However, for example, only bottom radiation is used for output switching.
When used with the top radiation stopped, the object to be heated is heated by the primary radiation A from the rotating antenna 6b and the secondary radiation B reflected on the heating chamber wall surface, but the rotating antenna 6a is stopped. Therefore, there is no stirring of the secondary radiation B, which causes uneven heating.
又、回転アンテナ６ａと加熱室壁面間に電界が集中して
、スパークが発生する危険がある。Furthermore, there is a risk that the electric field will concentrate between the rotating antenna 6a and the wall of the heating chamber, causing sparks.
本考案は上記にかんがみなされたもので、２個の回転ア
ンテナから電磁波を放射するものにおいて、一方のみの
放射を行う場合も他方の回転アンテナを回転させ、加熱
むらとスパークの発生を防止したものである。The present invention was developed in consideration of the above, and in a device that radiates electromagnetic waves from two rotating antennas, even when only one side is radiated, the other rotating antenna is rotated to prevent uneven heating and generation of sparks. It is.
以下、本考案の一実施例を第２図によって説明する。An embodiment of the present invention will be described below with reference to FIG.
回転アンテナ６ａは電磁波を放射していないが回転は続
けているので、回転アンテナ６ｂからの二次放射Ｂは、
それにより攪拌され加熱むらはなくなり、又電界の集中
も瞬間的でありスパークの発生はない。Since the rotating antenna 6a does not radiate electromagnetic waves but continues to rotate, the secondary radiation B from the rotating antenna 6b is
As a result, the mixture is stirred and uneven heating is eliminated, and the concentration of the electric field is instantaneous and no sparks are generated.
−次放射Ａの一部が攪拌されるという効果もある。There is also the effect that part of the -order radiation A is stirred.
以上の如く、本考案によれば一方の放射による加熱の場
合でも、両方の回転アンテナの放射による場合と同様の
加熱むらの程度が得られ、又スパークの発生もないので
安全な装置とすることができる。As described above, according to the present invention, even in the case of heating by radiation from one side, the same level of heating unevenness can be obtained as when heating by radiation from both rotary antennas, and since no sparks are generated, the device is safe. Can be done.
