本発明は食品の加熱等に利用される加熱装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating device used for heating food, etc.

耐久性の点からホーロー処理がなされていた。2. Description of the Related Art As shown in FIG. 3, in a door body 1 of an open heating device generally used for heating food, etc., the punching portion 2 of the door body 1 is formed of a thin sheet metal material and is painted. The frame-shaped metal fitting 4 that fixes the glass screen 3 provided inside the punching part 2 and seals out hot air and radio waves in the heating chamber is made of sheet metal material, and when the door body 1 opens vertically. Enamel treatment was performed for durability against abrasion caused by putting in and taking out food 6.
発明が解決しようとする問題点
ところが金具4をパンチング部2と別体で構成すると、

望ましかった。Problems to be Solved by the Invention However, if the metal fitting 4 is constructed separately from the punching part 2,
It is necessary to fix the metal fitting 4 by means such as screws, which makes it difficult to clean the top, which is undesirable in appearance.
Since the cost is also high, it is desirable to construct the punching part 2 and the metal fitting 4 from a single sheet metal material, or to integrate separate parts by spot welding or the like and then enamel them.

た。However, when trying to enameling the punching part 2, the punching part 2 was exposed to the high temperature (approximately 800℃) during enameling.
Distorted by 'C). The punching part 2 has small holes formed at a high density to improve the perspective effect, so the distortion after the punching process is large and undulates considerably. Usually, a flattening process called a leveler is applied after the punching process, so that the surface becomes flat in appearance when it is cold or at a temperature of about 300°C, which is about the same temperature as normal paint baking. However, when firing the enamel, there was a problem of extremely large waves.
本発明はこのような従来の問題点を解決するものであり
、パンチング部を含む扉体のホーロー処理を可能にし安
価で外観及び使い勝手の良い扉体とするものである。The present invention solves these conventional problems, and enables the door body including the punching portion to be enameled, thereby providing a door body that is inexpensive, has a good appearance, and is easy to use.

ある。Means for Solving the Problems The heating device of the present invention has a door body that opens vertically, and includes a mouth-shaped seal portion made of a sheet metal material that abuts at least the peripheral edge of the opening of the heating chamber, and an inner side of the seal portion. A punching portion made of a sheet metal material provided integrally with the punching portion is curved, and the sealing portion and the punching portion are enameled.

。Function The present invention prevents the punching surface from being deformed by the high temperature (approximately 800° C.) during enamel firing by giving a curve to the punching surface of the vertically opening door body. That is,
In addition to removing distortion during the punching process, by making the punching convex in a certain direction, if the punching stretches and bulges during heating,
It swells in a certain direction, eliminates irregular punching irregularities, and no unnatural irregularities occur on the punched surface after the enamel treatment. In this way, the door body can be enameled, unnecessary screws can be eliminated, the appearance is improved, the usability for cleaning etc. is improved, and the cost can be reduced. In particular, since the door body opens vertically, the heated object will slide on the door body when storing and taking out the heated object, but since there are no screws, there is no chance of anything getting caught, and the enamel treatment prevents scratches. There is very little to worry about.
実施例
以下本発明の一実施例の加熱装置を図面を参照して説明
する。EXAMPLE Hereinafter, a heating device according to an example of the present invention will be explained with reference to the drawings.
第1図に示すようにヒータ1と高周波発振装置2を備え

4内の熱気ヤニオイ、電波等がもれるのを防いでいる。As shown in FIG. 1, a door body 6 for opening and closing a heating chamber 4 of a heating device 3 equipped with a heater 1 and a high-frequency oscillator 2 is pivotally supported to the heating chamber 4 so as to be openable and closable. The mouth-shaped seal portion 7 of the door body 5 is configured to come into contact with the heating chamber opening periphery 6, and hot air smell, radio waves, etc. in the heating chamber 4 leak from the heating chamber opening periphery 6. It prevents

なされている。The seal portion 7 is made of a sheet metal material, and a punching portion 8 having a spherical shape and projecting toward the side opposite to the heating chamber 4 is integrally formed in the center thereof. On the opposite side of the sealing part 7 from the heating chamber 4, there is provided an outer frame 1o made of a blank sheet metal material constituting a choke groove 9 for slow closing of radio waves.
The punching portion 8 and the outer frame 1o are enameled after being integrated.

可能になった。A transparent glass screen 11 is provided on the heating chamber 4 side of the punching section 8 with its periphery fixed with silicone putty 12, and the outer frame 10 is provided with a handle 13 for opening and closing the door body ε. . With the above configuration, the sealing part 7, punching part 8, and outer frame 10 can be enameled after being integrated.

る。In the case of the door body 5 of the vertical opening type as in the embodiment, the seal part 7 will be frequently rubbed when the object to be heated 14 is taken in and out of the heating chamber 4, but if the surface treatment is enamel, the hardness will also be reduced. It is hard and has a thick film, so there is no problem in terms of durability, and since the seal part 7 is not attached later with screws, it has a good appearance.
It is also easy to use, with no difficulty in cleaning due to the protrusions of the screws. Also, since surface treatment can be done all at once, it is advantageous in terms of cost. In this embodiment, the sealing part 7 and the punching part 8 are formed of a single sheet metal material, but it is of course possible to form them separately, integrate them by spot welding, caulking, etc., and then enamel them. If the curvature of the punching part 8 is convex on the side opposite to the transparent screen IJ-n 11, the screen 11 will not be bent even if the temperature of the heating chamber 4 rises due to the heat of the heater 1 when the oven 3 is used and the punching part 8 expands. This is advantageous because it does not have any negative effects when pressed.
発明の効果
以上のように本発明のオープン用扉体は、■ パンチン
グ部を湾曲させる事によシホーロー処理が外観上の変形
なく可能になった。Effects of the Invention As described above, the opening door body of the present invention has the following features: (1) By curving the punching portion, it is possible to perform a hollow process without deforming the appearance.
■ 上記湾曲を球面とする事により、特に安定した仕上
げ面が得られるようになった。■ By making the above curve a spherical surface, a particularly stable finished surface can be obtained.
■ シール部とパンチング部を一体的に構成でき、ビス
が不要になったので外観が良くなり、掃除等使い勝手が
良くなった。又一体化してもホーロー処理ができる事か
ら、扉体内面の耐久性が損なわれず、被加熱物が扉体上
をすべる縦開きの扉体において非常に有用である。■ The sealing part and punching part can be constructed as one unit, eliminating the need for screws, which improves the appearance and makes cleaning easier. Furthermore, since the enameling process can be performed even when integrated, the durability of the inner surface of the door body is not impaired, and it is very useful for vertically opening door bodies where objects to be heated slide on the door body.
■ ホーロー処理は塗装よシもはるかに高い耐熱性と耐
こすれの性能が得られるにもかかわらず、耐熱塗装に比
べると安価で加熱室内が高温(100’C〜soo°C
)になるオープン加熱装置ではコスト的に有利である。■ Even though enamel treatment has much higher heat resistance and scratch resistance than paint, it is less expensive than heat-resistant paint and has a high temperature inside the heating chamber (100'C to soo°C).
) is advantageous in terms of cost.
■ 従来のように、ホーロー処理後シール部をビス止め
するといった作業が不要なので、ホーローの割れによる
不良の発生を少なくできる。■ Unlike conventional methods, there is no need to screw the seal part after enamel treatment, which reduces the occurrence of defects due to cracks in the enamel.
すなわちシール部はチョーク構造になる場合、相当小さ
なピッチでビス止めする必要があり、ビスの本数が多く
ビス締めの際のホーローの割れが多発していたが、本発
明はこの欠点を解除するものである。In other words, when the seal part has a choke structure, it is necessary to fasten with screws at a fairly small pitch, and the number of screws is large, resulting in frequent cracking of the enamel when tightening the screws.The present invention eliminates this drawback. It is.
