十分である。前記加熱室の金属箱は、被加熱物を
内部に収納するので加熱室壁面に不必要な突部を
生じないよう前述の溶接やかしめ部分は箱の外側
に位置するよう構成される。Conventional structure and its problems The structure of the casing of a conventional high-frequency heating device such as a microwave oven consists of a heating chamber, a bottom plate, and an outer shell. Using folding or the like, a box-shaped body is formed by attaching a body with a substantially square cross section, a front plate having an opening approximately the same size as the cross-section of the body on the front side, and a back plate closing the opening on the rear side; A common method is to then paint the inner surface. There are also cases in which the heating chamber is constructed using stainless steel plates and no post-coating is performed, but in cases where the heating chamber reaches a high temperature, such as in ovens and microwave ovens, it is possible to use only ordinary high-frequency heating. If so, a steel plate painting configuration is sufficient. Since the metal box of the heating chamber stores the object to be heated inside, the welded and caulked portions described above are located outside the box so as not to form unnecessary protrusions on the wall surface of the heating chamber.

部品を収納する電気室として利用できるようにし
ている。 Further, the front plate and the back plate are extended to the right, above, or below the outer surface of the metal box body by more than the flange length required for welding and caulking, and the outer wall of the metal box and the front plate and A small space is formed that is surrounded on three sides by the extension of the back plate, and this space is equipped with a high-frequency generator and a high-frequency introduction means for supplying high-frequency waves to the heating chamber, as well as mechanical and electrical equipment for control. It can be used as an electrical room to store control parts.

を利用して取付けられる。 The metal box in which the electric chamber and the heating chamber are integrally formed in this way is mounted on a rigid and stable bottom plate using screws or other fastening means. Further, a hinge for a door that can be opened and closed and covers the opening of the front plate of the heating chamber can be attached using the bottom plate and a part of the metal box.

取付けることもある。 The metal box and bottom plate of the above configuration have exposed flange parts that have been welded and caulked, various mechanisms and electrical components, wiring for connecting them, screws for fastening, etc. In order to cover it, an outer shell made of a metal plate processed into a roughly U-shape is attached. Sometimes, a back plate is also attached to the back of the heating chamber back plate to cover small parts attached to the outside.
一般的には以上のような筐体構成であるから、

ては２回あるいはそれ以上に分割して加熱するこ
とを余儀なくされ、結果的には加熱時間を長びか
せ、かつ投入電気エネルギーの消費量も大きくな
る。 Generally, the housing configuration is as shown above, so
The device has a so-called double structure, which reduces the effective volume of the heating chamber relative to the external dimensions. This results in an unnecessarily large installation area or occupied space of the device. In addition, the size of the object to be heated that can be stored in the heating chamber is relatively limited, and in some cases, when heating the desired amount of object, it is necessary to heat the object in two or more times. As a result, the heating time becomes longer and the amount of electrical energy consumed increases.
以上のように設置スペースが大きいこと、加熱
時間が長くかかること、消費電気量が多いことな
どの欠点があつた。 As mentioned above, there are disadvantages such as a large installation space, a long heating time, and a large amount of electricity consumption.
更に２重構造の筐体は、外郭材ならび加熱室と
もに金属材料であつて重量軽減も困難で、運搬に
支障をきたし、かつ包装部材も丈夫なものを必要
とする等コスト面でも高いものになつていた。 Furthermore, the double-layered casing is made of metal for both the outer shell and the heating chamber, making it difficult to reduce the weight, making it difficult to transport, and requiring strong packaging materials, resulting in high costs. I was getting used to it.
上記の欠点を解消するものとして、外郭材と加
熱室を一体構造にし、一重壁としたものも見受け

施するものである。なお、電気部品や機構部品の
取付けは前記電気室外側に設けた開口部より作業
する。 In order to solve the above drawbacks, there are some cases in which the outer shell material and the heating chamber are integrated into a single wall (European Patent Application0110364
etc.), but in this case, the heating chamber, which has an outer wall that serves as the outer shell material, and the electrical chamber are formed using separate body plates, and after joining the two using means such as spot welding, the front and back plates are attached. They are joined together to form a casing, which is then painted after completion. In addition, the installation of electrical parts and mechanical parts is carried out through the opening provided on the outside of the electrical room.
このような構成によれば、筐体は一重構成で、
設置スペースの削減や軽量化に効果があるが、加
熱室内部と外部とが同色となり、装置として外面
の色と加熱室内の色とを異色にしたい場合には塗
装の方法が極めて難しい。 According to such a configuration, the casing has a single layer configuration,
Although it is effective in reducing the installation space and weight, the inside and outside of the heating chamber are the same color, and if you want to make the outside color of the device different from the color inside the heating chamber, the painting method is extremely difficult.
また加熱室と電気室との境界線が胴板の外表面
に残つており、意匠的にも著しく欠点となる。 Furthermore, the boundary line between the heating chamber and the electrical chamber remains on the outer surface of the body plate, which is a significant design defect.
更に加熱室前板の開口は胴板の内部断面より小

例えば吹き付け塗装の場合には前記前板開口周辺
の内側に塗装が付きにくく、また浸漬塗装の場合
には逆に塗装あるいは溶剤の排出が困難である、
という製造工法上の欠点があつた。 Furthermore, the opening in the front plate of the heating chamber is smaller than the internal cross section of the body plate. This is because a metal wall surface facing the high frequency attenuation device provided around the periphery of the door covering the opening is required, so when painting the inside of the heating chamber,
For example, in the case of spray painting, it is difficult to get the paint on the inside around the front plate opening, and in the case of dip painting, it is difficult to paint or drain the solvent.
There was a drawback in the manufacturing method.

することを目的とする。Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks.The effective volume of the heating chamber is large in relation to the external dimensions of the device, and it is possible to reduce the weight.There is no problem with the manufacturing or painting method, and the interior and exterior of the heating chamber can be discolored. The purpose of the present invention is to provide a housing structure for a high-frequency heating device that can be painted and has no defects in design.

加熱装置である。Structure of the Invention In order to achieve the above-mentioned object, the structure of the present invention is as follows: a body plate having a substantially square stepped surface which is coated on both sides in advance; Then, a metal box is formed by a seaming process in which the three parts of the back plate and the front plate having the same size and having an opening for entering and exiting the heated object at the upper part are respectively connected. A metal partition plate is installed inside the front plate slightly below the opening for entering and exiting the heated material to divide it into upper and lower parts, and the lower part of the partition plate is used as an electrical room for storing the high frequency generator and its control parts. A flat plate made of a material with a low dielectric constant is provided horizontally on the bottom surface so as to coincide with the lower end of the opening of the cylinder, and the upper part thereof is used as a heating chamber, and high frequency introducing means is provided between the partition plate and the flat plate. This is a high-frequency heating device in which the outer peripheral surface of the plate also serves as the outer shell of the device.
