【産業上の利用分野】[Industrial applications]

本考案は、電子レンジ等の高周波加熱装置の被加熱物を加熱調理する加熱室の 構成に関するものである。 The present invention relates to a structure of a heating chamber for heating and heating an object to be heated of a high frequency heating device such as a microwave oven.

【0002】[0002]

【従来の技術】[Prior art]

一般に、電子レンジ等の高周波加熱装置には加熱室の雰囲気温度を上昇させる ヒーターユニットが設けられており、このヒーターユニットを収納するヒーター カバーは別部材で形成され加熱室の壁面にスポット溶接にて取り付けられていた 。 そして、特開平1−296588号には第4図に示す如く、ヒーターカバー をヒーターカバー本体13と加熱室壁面を切り起こして一体形成したヒーターカ バー側板12a,12bとによって構成することを特徴とする発明が開示されて いる。 Generally, a high-frequency heating device such as a microwave oven is provided with a heater unit for raising the ambient temperature of the heating chamber, and the heater cover for housing this heater unit is formed as a separate member by spot welding on the wall of the heating chamber.

【考案が解決しようとする課題】[Problems to be solved by the device]

上記特開平1−296588号に開示された発明によれば、確かに、ヒーター カバー側板12a,12bが加熱室壁面と一体化された部分のスポット溶接箇所 を減少させることができ、スポット溶接箇所の減少に伴って加熱室からの電波漏 洩を少なくすることができるのであるが、あくまでもヒーターカバー本体13が 別体であるため、ヒーターカバー本体13の材料費,加工費と加熱室壁面への取 り付け加工費とが必要で製造原価が高く、一方、ヒーターカバー本体13の加熱 室壁面への取り付け加工を自動化するのが客観的に見て容易でない上、ヒーター カバー本体13に対向する加熱室壁面を切除して開口部を形成するためにできる 廃材の量が多いという課題を残していた。 According to the invention disclosed in Japanese Patent Laid-Open No. 1-296588, it is possible to reduce the number of spot welding points where the heater cover side plates 12a and 12b are integrated with the heating chamber wall surface. With the decrease, it is possible to reduce the radio wave leakage from the heating chamber, but since the heater cover body 13 is a separate body, the material cost of the heater cover body 13, the processing cost, and the installation on the heating chamber wall surface. It is difficult to objectively automate the process of attaching the heater cover body 13 to the wall of the heating chamber, and the heating chamber facing the heater cover body 13 is required. There was a problem that a large amount of waste material could be produced by cutting the wall surface to form the opening.

【課題を解決するための手段】[Means for Solving the Problems]

上記の課題を解決するために本考案の高周波加熱装置は、 ヒーターユニットを収納するヒーターユニット収納部を加熱室壁面と一体に形 成する。ヒーターユニット収納部を一体形成する加熱室壁面は実施例にて開示す る加熱室天面の他、底面,背面が考えられ特に限定されるものではない。又、加 熱室壁面でヒーターユニット収納部を一体に形成する構造は折り曲げ加工による ものと絞り加工によるものが考えられる。 In order to solve the above-mentioned problems, the high-frequency heating device of the present invention forms a heater unit housing part for housing the heater unit integrally with the wall surface of the heating chamber. The wall surface of the heating chamber that integrally forms the heater unit housing is not limited to the top surface of the heating chamber shown in the embodiment, as well as the bottom surface and the back surface. Further, the structure of integrally forming the heater unit housing portion on the wall surface of the heating chamber may be a bending process or a drawing process.

【0005】[0005]

【作用】[Action]

ヒーターユニットを収納するヒーターユニット収納部を加熱室壁面と一体に形 成することにより、折り曲げ加工によるものにあっては特開平1−296588 号に開示されたものに比べ加熱室壁面と一体化された部分が多いため、よりスポ ット溶接箇所を減少させることができスポット溶接箇所の減少に伴う加熱室から の電波漏洩を少なくすることができる。絞り加工によるものにあってはヒーター ユニット収納部のスポット溶接を皆無にできヒーターユニット収納部からの電波 漏洩(ヒーターユニット貫通部からの電波漏洩を除く)をほぼ皆無にできる。 By forming the heater unit housing portion for housing the heater unit integrally with the wall surface of the heating chamber, the bending process is integrated with the wall surface of the heating chamber as compared with the one disclosed in JP-A-1-296588. Since there are many broken spots, spot welding points can be further reduced, and radio wave leakage from the heating chamber due to the reduction of spot welding points can be reduced. With the drawing process, spot welding of the heater unit housing can be eliminated altogether, and radio wave leakage from the heater unit housing (excluding radio wave leakage from the heater unit penetration) can be eliminated almost completely.

【0006】 又、加熱室壁面にヒーターユニット収納部を一体に形成すると、ヒーターユニ ット収納部を一体に形成しないものに比べ材料費,加工費(加工行程)が幾分増加 するが、特開平1−296588号に開示されている如く別体のヒーターカバー を設けるものに比べると材料費,加工費を低減することができ、加熱室壁面への 取り付け加工費も不要となるため総計的に大幅なコストダウンが計れる。 更に、加熱室壁面にヒータユニット収納部を一体形成する加工行程は自動化が 容易であり、自動化することにより更なるコストダウンが可能となる。Further, when the heater unit housing is integrally formed on the wall surface of the heating chamber, the material cost and the processing cost (processing stroke) are slightly increased as compared with the case where the heater unit housing is not integrally formed. Compared to the one with a separate heater cover as disclosed in Kaihei 1-296588, the material cost and the processing cost can be reduced, and the mounting and processing cost on the wall of the heating chamber is not necessary, so that the total cost is reduced. Significant cost reduction can be achieved. Further, the process of integrally forming the heater unit housing portion on the wall surface of the heating chamber is easy to automate, and the automation can further reduce the cost.

【実施例】【Example】

以下、本考案の高周波加熱装置に係る加熱室の一実施例を図面に基づき説明す る。 図1に示すように加熱室1は、開口部を設けた加熱室前板2とU字形状に折り 曲げ加工された加熱室胴板3と加熱室天板4と加熱室底板5とから構成される。 そして、前記加熱室天板4にはヒーターユニット6を収納するヒーターユニット 収納部7を一体に形成しており、本考案の特徴部分であるヒーターユニット収納 部7の一体形成について以下説明する。 An embodiment of a heating chamber according to the high-frequency heating device of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the heating chamber 1 includes a heating chamber front plate 2 having an opening, a heating chamber body plate 3 which is bent into a U shape, a heating chamber top plate 4, and a heating chamber bottom plate 5. To be done. A heater unit housing portion 7 for housing the heater unit 6 is integrally formed in the heating chamber top plate 4. The integral formation of the heater unit housing portion 7, which is a feature of the present invention, will be described below.

【0008】 図2はヒーターユニット収納部7を一体に形成した加熱室天板4の上面図であ り、図3は加熱室天板4の右半分を展開した図である。図3の展開図において破 線は山折り箇所を示し1点鎖線は谷折り箇所を示す。FIG. 2 is a top view of the heating chamber top plate 4 integrally formed with the heater unit housing portion 7, and FIG. 3 is a developed view of the right half of the heating chamber top plate 4. In the developed view of FIG. 3, broken lines indicate mountain folds, and alternate long and short dash lines indicate valley folds.

【0009】 加工行程としては、所定外形寸法の薄鋼板から穴明け,切り欠き加工により図 3の展開図に示す形状にプレス加工し、次に水平重合片7aを段付け加工し傾斜 重合片7bを直角曲げ加工する。次にヒーターユニット収納部7を曲げ加工にて 形成し、重合片7a,7bを適宜スポット溶接にて固定することにより、ヒータ ーユニット収納部7を一体形成した加熱室天板4ができあがる。 尚、本実施例はヒーターユニット6を1本設けた場合であるが、2本以上設け た場合の方が薄鋼板の材料を合理的に使用することになり効果が増長される。As a working step, a thin steel plate having a predetermined outer dimension is punched and cut into a shape shown in the development view of FIG. 3, and then the horizontal overlapping piece 7a is stepped and inclined to overlap the overlapping piece 7b. Bend at a right angle. Next, the heater unit housing 7 is formed by bending, and the overlapping pieces 7a and 7b are appropriately fixed by spot welding to complete the heating chamber top plate 4 integrally formed with the heater unit housing 7. In this embodiment, one heater unit 6 is provided, but when two or more heater units 6 are provided, the material of the thin steel plate is used rationally, and the effect is enhanced.

【0010】 又、ヒーターユニット6を2本以上設ける場合にはヒーターユニット収納部の 平面的な大きさが大きくなって絞り加工しやすい形状となるため、絞り加工にて ヒーターユニット収納部を加熱室天板に一体成型し、ヒーターユニット貫通孔を 穿設して加熱室天板の外形を整えることにより、絞り加工にてヒーターユニット 収納部を一体形成した加熱室天板を製造することができる 上記した如く、ヒーターユニットを収納するヒーターユニット収納部を加熱室 壁面と一体に形成することにより、折り曲げ加工によるものにあっては特開平1 −296588号に開示されたものに比べ加熱室壁面と一体化された部分が多い ため、よりスポット溶接箇所を減少させることができスポット溶接箇所の減少に 伴う加熱室からの電波漏洩を少なくすることができる。絞り加工によるものにあ ってはヒーターユニット収納部のスポット溶接を皆無にできヒーターユニット収 納部からの電波漏洩(ヒーターユニット貫通部からの電波漏洩を除く)をほぼ皆無 にできる。In addition, when two or more heater units 6 are provided, the planar size of the heater unit housing portion becomes large and the shape becomes easy to draw. Therefore, the heater unit housing portion is drawn into the heating chamber by drawing. It is possible to manufacture a heating chamber top plate that is integrally formed with the heater unit housing by forming it integrally with the top plate and adjusting the outer shape of the heating chamber top plate by forming a heater unit through hole. As described above, by forming the heater unit housing portion for housing the heater unit integrally with the wall surface of the heating chamber, in the case of the bending process, it is integrated with the wall surface of the heating chamber as compared with the one disclosed in JP-A-1-296588. Since there are many parts that have been turned into spots, it is possible to further reduce the number of spot welding points, and the number of spot welding points decreases, causing radio wave leakage from the heating chamber. Can be reduced. With the drawing process, spot welding of the heater unit housing can be eliminated altogether, and radio wave leakage from the heater unit housing (excluding radio wave leakage from the heater unit penetration) can be almost eliminated.

【0011】 又、加熱室壁面にヒーターユニット収納部を一体に形成すると、ヒーターユニ ット収納部を一体に形成しないものに比べ材料費,加工費(加工行程)が幾分増加 するが、特開平1−296588号に開示されている如く別体のヒーターカバー を設けるものに比べると材料費,加工費を低減することができ、加熱室壁面への 取り付け加工費も不要となるため総計的に大幅なコストダウンが計れる。 尚、図1中の8はヒーターユニット6を加熱室天板4に固定する金具であり、 取付けビスにて加熱室天板4に固定されるようになっている。Further, if the heater unit housing is integrally formed on the wall surface of the heating chamber, the material cost and the processing cost (processing stroke) are slightly increased as compared with the case where the heater unit housing is not integrally formed. Compared to the one with a separate heater cover as disclosed in Kaihei 1-296588, the material cost and the processing cost can be reduced, and the mounting and processing cost on the wall surface of the heating chamber is not required. Significant cost reduction can be achieved. Reference numeral 8 in FIG. 1 denotes a metal fitting for fixing the heater unit 6 to the heating chamber top plate 4, which is fixed to the heating chamber top plate 4 with a mounting screw.
