Description

炊飯器rice cooker
　本発明は、炊飯器に関する。 The present invention relates to a rice cooker.
　炊飯器などの外枠は、デザイン性等から、樹脂や金属で構成されているものが一般的である。また、炊飯器は、本体外へ漏れる磁界を低減するため、加熱コイルから発する磁界を防磁板を設けて低減することが一般的である。そのような炊飯器において、外枠が金属で構成される炊飯器は、防磁板を設置せずに、外枠の金属で外部に磁界が漏れるのを防いでいる（例えば、特許文献１参照）。 The outer frame of a rice cooker, etc. is generally made of resin or metal for design reasons. In order to reduce the magnetic field leaking out of the main body of the rice cooker, it is common to provide a magnetic shield plate to reduce the magnetic field emitted from the heating coil. Among such rice cookers, a rice cooker whose outer frame is made of metal prevents the magnetic field from leaking to the outside without installing a magnetic shield plate (see, for example, Patent Document 1). .
　外枠が金属で構成される炊飯器は、長尺な四角形状の板金（金属板）をリング状に湾曲させ、板金の一組の対辺（長手方向における両方の端辺）を互いにかしめる（継ぎ目を工具で固く密着させる）ことにより、長尺な四角形状の板金から円筒状の外枠を形成している。このような外枠が金属で構成される炊飯器は、加熱コイルから発する磁界を金属の外枠で防磁することにより、本体外へ漏れる磁界を低減している。このような外枠が金属で構成される炊飯器は、防磁板を排除できるため、部品数を減らすとともに、防磁板の設置によって外枠の外形が大型化してしまうのを回避することができるため、コンパクトなデザインが可能となる。 A rice cooker whose outer frame is made of metal is made by bending a long rectangular sheet metal (metal plate) into a ring shape and crimping a pair of opposite sides (both sides in the longitudinal direction) of the sheet metal ( A cylindrical outer frame is formed from a long rectangular sheet metal by pressing the seams firmly with a tool. Such a rice cooker having a metal outer frame shields the magnetic field emitted from the heating coil with the metal outer frame, thereby reducing the magnetic field leaking out of the body. Since a rice cooker whose outer frame is made of metal can eliminate magnetic shields, it is possible to reduce the number of parts and to avoid an increase in the size of the outer frame due to the installation of magnetic shields. , a compact design is possible.

　特許文献１に記載された従来技術のように、外枠が金属で構成される炊飯器は、長尺な四角形状の板金の一組の対辺（長手方向における両方の端辺）を互いにかしめることにより外枠を形成する。その際の、かしめる前の板金をリング状に湾曲させたセット状態において、かしめを行う部位（かしめ部）に上下左右にズレが生じることがあり、ズレが生じた状態でかしめてしまう、という課題がある。また、ズレが生じた外枠は、本体を組み合わせたときに、上枠との間や下枠との間にズレが生じ、上枠との間や下枠との間に段差が生じてしまうため、炊飯器の外観を損なってしまう、という課題がある。 As in the prior art described in Patent Document 1, a rice cooker whose outer frame is made of metal is formed by crimping a pair of opposite sides (both sides in the longitudinal direction) of a long rectangular sheet metal. This forms an outer frame. At that time, when the sheet metal is curved into a ring before being crimped, the part to be crimped (crimped part) may be misaligned vertically and horizontally, and crimping is done in a state of misalignment. I have a problem. In addition, when the outer frame is misaligned, it will be misaligned with the upper frame and the lower frame when the main body is assembled, and a step will occur between the upper frame and the lower frame. Therefore, there is a problem that the appearance of the rice cooker is spoiled.
　前記目的を達成するため、本発明は、炊飯器であって、炊飯器本体と、前記炊飯器本体に着脱自在に収納する鍋と、前記鍋を誘導加熱する加熱コイルと、前記加熱コイルの動作を制御する加熱制御部と、を備え、前記炊飯器本体は、前記鍋と前記加熱コイルとを覆う外枠を有し、前記外枠は、長尺な四角形状の板金の長手方向における両方の端辺をかしめることにより円筒状に形成されており、かつ、一方の端辺には穴部が設けられ、他方の端辺には前記穴部に嵌合する凸部が設けられている構成とする。
　その他の手段は、後記する。 To achieve the above object, the present invention provides a rice cooker comprising a rice cooker body, a pan detachably housed in the rice cooker body, a heating coil for induction heating the pan, and operation of the heating coil. The rice cooker main body has an outer frame that covers the pot and the heating coil, and the outer frame is a long rectangular sheet metal in the longitudinal direction. It is formed into a cylindrical shape by crimping the edges, and has a hole in one edge and a protrusion that fits into the hole in the other edge. and
Other means will be described later.

　図３に示すように、かしめ部２３の一方の端辺４ａには穴部２４が設けられ、他方の端辺４ｂには穴部２４に嵌合する凸部２５が設けられている。穴部２４と凸部２５は、一方の端辺４ａと他方の端辺４ｂにおいて、円筒状の外枠４の内周面に臨む位置に設けられている。一方の端辺４ａと他方の端辺４ｂは、互いが係合するようにコ字状の形状を呈している。したがって、穴部２４は、コ字状の形状に形成された一方の端辺４ａの内周面側の位置に設けられ、また、凸部２５は、コ字状の形状に形成された他方の端辺４ｂの内周面側の位置に設けられている。外枠４は、それぞれがコ字状の形状に形成された２つの端辺４ａと端辺４ｂとを嵌め合わせ、穴部２４と凸部２５とでかしめ部２３の位置を合わせてから、その部分をかしめることで、密着（圧着）させ、かしめ部２３が形成される。なお、「かしめる」とは、金属の接合部分を打ったり締めたりして固く止めることをいう（広辞苑第７版）。 As shown in FIG. 3, a hole 24 is provided on one edge 4a of the crimped part 23, and a protrusion 25 that fits into the hole 24 is provided on the other edge 4b. The hole portion 24 and the projection portion 25 are provided at positions facing the inner peripheral surface of the cylindrical outer frame 4 at one end side 4a and the other end side 4b. One edge 4a and the other edge 4b are U-shaped so as to be engaged with each other. Therefore, the hole portion 24 is provided at a position on the inner peripheral surface side of one of the U-shaped edges 4a, and the convex portion 25 is provided on the other side of the U-shaped edge. It is provided at a position on the inner peripheral surface side of the edge 4b. The outer frame 4 is formed by fitting two edges 4a and 4b, each formed in a U-shape, and aligning the positions of the crimped portions 23 with the holes 24 and the projections 25, and then By crimping the part, they are brought into close contact (compression), and the crimped portion 23 is formed. "Caulking" means to firmly fasten a metal joint by hammering or tightening it (Kojien 7th edition).
　このような外枠４は、穴部２４と凸部２５とでかしめ部２３の位置を正確に合わせることができるため、かしめ部２３に上下左右の位置ズレが発生することを防止することができる。そのため、炊飯器１００は、上枠３と下枠５とに外枠４を組み合わせたときに上枠３と外枠４との間及び下枠５と外枠４との間に段差が生じことを防止することができ、炊飯器１００の外観が損なわれることを防止することができる。 With such an outer frame 4, the position of the caulked portion 23 can be accurately aligned with the hole portion 24 and the convex portion 25, so that the caulked portion 23 can be prevented from being displaced in the vertical and horizontal directions. . Therefore, in the rice cooker 100, when the outer frame 4 is combined with the upper frame 3 and the lower frame 5, there is no difference in level between the upper frame 3 and the outer frame 4 and between the lower frame 5 and the outer frame 4. can be prevented, and the appearance of the rice cooker 100 can be prevented from being spoiled.
