ンドル３の操作によって開閉自在に装着されるドア４本
体が位置している。In FIGS. 1 to 3, a heating chamber 2 with an opening on one side is located inside the main body 1, and a door 4 body is attached to the opening of the heating chamber 2 so that it can be opened and closed by operating a handle 3. is located.
加熱室２には被加熱物が置かれマグネトロ７（図示せず
）から照決された高周波によって誘電加熱される構成に
なっている。An object to be heated is placed in the heating chamber 2 and dielectrically heated by high frequency waves emitted from a magnetron 7 (not shown).
次に本構造の要部であるドア４本体について説明する。Next, the main body of the door 4, which is the main part of this structure, will be explained.

ている。The door frame 6, which is made of a metal body and has a hole in the center for seeing through the object to be heated, forms the frame of the door 4 body and has many small holes. The first step is to prevent radio wave leakage. Further, together with a slit plate 7 made of a metal body and having slits perpendicular to the main body of the door 4, a first cavity 8 and a second cavity 9 are constituted to perform the second stage of radio wave leakage prevention.

ャビティの中に誘電体１０を入れた場合のキャビティの
実質的長さは下記の公式で表わされる。At this time, the first cavity 8 is filled with a dielectric 10 in order to simplify the structure of the cavity and to make the viewing window of the door frame 5 as wide as possible. The substantial length of the cavity when the dielectric 10 is placed in the cavity is expressed by the following formula.
λ：ｖ５電体の波長
λ０：真空中の高周波の波長
εｒ：比誘電率
誘電体１ｏは誘電体損失の少なく成形加工も簡単なポリ
プロピレンなどの合成樹脂が考えられこの場合、比誘電

Ｌ型から１型になり簡単な構造が可能となった。λ: v5 Wavelength of electric material λ0: Wavelength of high frequency in vacuum εr: Relative permittivity The dielectric 1o can be made of synthetic resin such as polypropylene, which has low dielectric loss and is easy to mold.In this case, the relative permittivity εr is 2 to 3, and the wavelength is 1.4 to 1.
7 and the cavity size is the same as the conventional A b-30.
The mm has become smaller, and the cavity structure has changed from the conventional L-shape to a 1-shape, making it possible to create a simpler structure.
第２キャビティ９部には本実施１０においては誘電体１
０に相当する合成樹脂体を設けていないがこのキャビテ
ィ部は第３段階の電波漏洩防止のため筒周波の漏洩も少
ないため今回の実施例には適用する必要がない。In the present embodiment 10, the second cavity 9 has a dielectric material 1.
Although the synthetic resin body corresponding to 0 is not provided, this cavity part does not need to be applied to the present embodiment because there is little leakage of cylindrical frequency waves due to the prevention of radio wave leakage in the third stage.
