（産業上の利用分野）
本考案は電子レンジにおいて加熱室を構成する
内箱に係り、特に内壁面に塗装を施した内箱に関
するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an inner box constituting a heating chamber in a microwave oven, and particularly relates to an inner box whose inner wall surface is coated.
（従来の技術）
一般に、電子レンジにおいては、第１図及び第
２図に示すように、塗装鉄板よりなり内部を加熱
室２とする内箱１の天井壁部３に多数の小孔４を

小孔４群から排気ダクトを経て外部に排出するよ
うになつている。(Prior Art) Generally, in a microwave oven, as shown in FIGS. 1 and 2, a large number of small holes 4 are formed in the ceiling wall 3 of an inner box 1 made of a painted iron plate and having a heating chamber 2 inside. The structure is such that the four groups of small holes serve as exhaust ports, and steam, smoke, etc. generated during heating of food are discharged from the four groups of small holes to the outside via an exhaust duct.
（考案が解決しようとする問題点）
ところで、従来においては上記小孔４をパンチ

工程が増加し、コスト的に高くなるものであつ
た。(Problems to be Solved by the Invention) Conventionally, the small holes 4 were formed by punching holes, so the cut surface was visible from inside the inner box 1, and if rust occurred on the cut surface, It was extremely unsightly and unpleasant. In addition, in order to eliminate such unsightliness and discomfort, it is necessary to apply a rust-preventive coating after the punching process, which increases the number of work steps and increases costs. It was hot.
（問題点を解決するための手段）
本考案はかかる点に鑑みてなされたもので、小
孔をバーリング加工による絞り孔とし、この絞り
孔の筒状壁を外方に突出する。(Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems, and the small hole is made into a throttle hole by burring, and the cylindrical wall of this throttle hole protrudes outward.
（作用）
上記の構成により、筒状壁の先端においてさび

与えることがなくなる。(Function) With the above configuration, even if rust occurs at the tip of the cylindrical wall, the rust will not be visible from the heating chamber inside the inner box, and will not cause unsightliness or discomfort to the user.
（実施例）
以下第３図及び第４図に示した本考案の実施例
について説明する。(Example) An example of the present invention shown in FIGS. 3 and 4 will be described below.
４′は天井壁部３に形成した多数の小孔で、バ

である。 Numeral 4' denotes a number of small holes formed in the ceiling wall portion 3, which are constricted holes formed by burring. These constricted holes (small holes 4') are formed by burring from the inside of the ceiling wall portion 3, and the cylindrical wall 5 protrudes outward. Numeral 6 denotes a coating film formed by painting on the inner wall surface of the ceiling wall portion 3.
上記構成において、筒状壁５の先端面３′は切

熱室より見えない為、使用者に見苦しさや不快感
を与えることはない。又、筒状壁５の内面は加熱
室より見えるが、この面には塗装膜６があり、さ
びが発生することはない。 In the above configuration, the tip surface 3' of the cylindrical wall 5 is a cut surface and there is a risk of rust forming, but even if rust were to occur, the tip surface 3' would not be visible from the heating chamber inside the inner box. It does not cause any unsightliness or discomfort to the user. Further, although the inner surface of the cylindrical wall 5 is visible from the heating chamber, there is a coating film 6 on this surface, and rust will not occur on this surface.
尚、第４図においては筒状壁５の高さｈを実際
の寸法（天井壁部３の鉄板の厚みと略同じ、0.4
〜0.5mm）よりかなり拡大して記載している。 In addition, in FIG. 4, the height h of the cylindrical wall 5 is set to the actual dimension (approximately the same as the thickness of the iron plate of the ceiling wall 3, 0.4
~0.5mm).
（考案の効果）
以上の如く本考案にあつては、小孔をバーリン

化、コストダウン等を計ることができる。(Effects of the invention) As described above, in the present invention, the small hole is made into a throttle hole by burring processing, and the cylindrical wall of the throttle hole is made to protrude outward. Even if rust occurs on the tip surface, it will not be visible from inside the inner box, so it will not cause unsightliness or discomfort, and there will be no need to apply a special anti-rust coating, simplifying the work process. , cost reduction, etc. can be measured.
