Description

本発明は、電磁誘導加熱調理器の加熱コイルユニットに関する。   The present invention relates to a heating coil unit of an electromagnetic induction heating cooker.

一般に、電磁誘導加熱調理器においては、被加熱面となるポット、鍋、フライパン等の底面が略円形であることから、通常、この被加熱面の形状に沿うように略円形の加熱コイルユニットが広く使用されている（例えば、下記の特許文献１参照）。すなわち、この加熱コイルユニットは、耐熱樹脂成型品からなる絶縁性を有する円盤状の保持台を有し、この保持台の中心部には表面側に突出した円形の突起が形成されている。そして、この突起を中心として表面側にリッツ線からなる加熱コイルが渦巻き状に周回するように巻装されている。また、保持台の裏面側にはリブに沿ってフェライトコアが放射状に取り付けられている。   Generally, in an electromagnetic induction heating cooker, since the bottom surfaces of pots, pans, frying pans, and the like that are to be heated are substantially circular, a generally circular heating coil unit usually follows the shape of the heated surface. Widely used (for example, see Patent Document 1 below). That is, this heating coil unit has an insulating disk-shaped holding base made of a heat-resistant resin molded product, and a circular protrusion protruding to the surface side is formed at the center of the holding base. A heating coil made of litz wire is wound around the protrusion around the protrusion so as to circulate in a spiral shape. Moreover, the ferrite core is radially attached to the back surface side of the holding table along the rib.

ところで、電磁誘導加熱調理器の種類の内には、必ずしも被加熱面が円形のものに限らず、例えばお好み焼き、たこやき、鉄板焼き、茹で麺などの調理を行う場合のように、長方形の被加熱面を均一加熱することが必要となることがある。しかし、電磁誘導加熱調理器として、特許文献１に記載されているような渦巻き状に周回するように加熱コイルを巻装してなる略円形の加熱コイルユニットを使用する場合には、長方形の被加熱面を均一加熱することが困難である。   By the way, among the types of electromagnetic induction heating cookers, the surface to be heated is not necessarily a circular one. For example, when cooking okonomiyaki, takoyaki, teppanyaki, boiled noodles, etc. It may be necessary to heat the surface uniformly. However, in the case of using a substantially circular heating coil unit in which a heating coil is wound so as to circulate in a spiral shape as described in Patent Document 1, as an electromagnetic induction heating cooker, a rectangular covering is used. It is difficult to uniformly heat the heating surface.

そこで、従来は、長方形の被加熱面を均一に加熱するために、楕円形に周回された加熱コイルを成型するようにした技術が提案されている（例えば、下記の特許文献２参照）。すなわち、この従来技術では、楕円形の巻き取り金型を製作するとともに、加熱コイルの供給方向に沿って３つのローラを設け、各ローラで加熱コイルに曲げ力を付与して屈曲させながら巻き取り金型に巻き取ることで、楕円形に周回された加熱コイルを成型する。   Therefore, conventionally, in order to uniformly heat the rectangular surface to be heated, a technique has been proposed in which a heating coil that is wound in an elliptical shape is formed (for example, see Patent Document 2 below). That is, in this prior art, an elliptical winding mold is manufactured, and three rollers are provided along the heating coil supply direction, and each roller is wound while being bent by applying a bending force to the heating coil. By winding it around a mold, a heating coil that is circulated in an elliptical shape is formed.

特許第３００６１８４号公報Japanese Patent No. 3006184 特開昭５９−１３０６３７号公報JP 59-130637 A

ところで、上記の特許文献２記載の従来技術では、楕円形に周回された加熱コイルを成型することが可能であるものの、そのような成型を行う上で、専用の巻き取り金型や屈曲用のローラを設けねばならず、製作にコストがかかるという問題がある。   By the way, in the prior art described in Patent Document 2 described above, it is possible to mold an elliptical heating coil. However, when performing such molding, a dedicated winding die or a bending coil is used. There is a problem that it is necessary to provide a roller, and manufacturing costs are high.

すなわち、お好み焼き、たこやき、鉄板焼き、茹で麺などの業務用の調理器として使用される電磁誘導加熱調理器は、一般家庭用のものに比べると出荷台数が少ない上に、ポット、鍋、フライパン等のように被加熱面となる底面が略円形であるものに比べると、被加熱面の大きさも区々異なるため、少量多品種のものとなる。そのため、個々の要求に沿うように専用の巻き取り金型や屈曲用のローラを製作すると、膨大な費用と工数がかかるという不具合がある。   In other words, electromagnetic induction heating cookers that are used as business cookers such as okonomiyaki, takoyaki, teppanyaki, boiled noodles, etc. have fewer shipments than ordinary household ones, and pots, pans, pans, etc. Compared with the case where the bottom surface to be heated is substantially circular, the size of the surface to be heated is different depending on the area, so that it becomes a small variety of products. For this reason, when a dedicated winding die or a bending roller is manufactured to meet individual requirements, there is a problem that enormous costs and man-hours are required.

本発明は、上記の課題を解決するためになされたもので、非円形に周回された加熱コイルを容易にかつ安価に成型することができ、かつ少量多品種に対しても柔軟に対応することが可能な電磁誘導加熱調理器の加熱コイルユニットを提供することを目的とする。   The present invention has been made to solve the above-described problems, and can easily and inexpensively form a non-circular heating coil, and can flexibly cope with a small variety of products. An object of the present invention is to provide a heating coil unit of an electromagnetic induction heating cooker capable of performing the above.

上記の目的を達成するために、本発明は、次の構成を採用している。
すなわち、請求項１の発明に係る電磁誘導加熱調理器の加熱コイルユニットは、中心に突起が形成された円盤状の保持台を複数備え、各保持台が一つの固定基板上に取り付けられ、前記各保持台の前記突起に掛止された状態で各保持台間を周回するように加熱コイルが巻き付けられていることを特徴としている。 In order to achieve the above object, the present invention adopts the following configuration.
That is, the heating coil unit of the electromagnetic induction heating cooker according to the invention of claim 1 includes a plurality of disk-shaped holding bases each having a protrusion formed at the center, and each holding base is mounted on one fixed substrate, A heating coil is wound around the holding tables so as to circulate between the holding tables while being hooked on the protrusions of the holding tables.

また、請求項２の発明に係る電磁誘導加熱調理器の加熱コイルユニットは、請求項１記載の発明の構成において、前記各保持台には、前記加熱コイルの周回方向を横切るようにフェライトコアが配置されていることを特徴としている。   Moreover, the heating coil unit of the electromagnetic induction heating cooker according to the invention of claim 2 is the configuration of the invention of claim 1, wherein each holding base has a ferrite core so as to cross the circumferential direction of the heating coil. It is characterized by being arranged.

請求項１の発明によれば、標準的な電磁誘導加熱調理器の加熱コイルユニットを構成するための既存の円盤状の保持台の複数個をそのまま流用したかたちで、各保持台間を周回するように加熱コイルを巻き付けることにより、非円形の加熱コイルユニットを構成することができる。このため、専用の巻き取り金型や屈曲用のローラを設ける必要がないので、加熱コイルユニットを安価に製作することができ、しかも、被加熱面の大きさが大小異なる場合でも保持台の直径や加熱コイルの直径を変更するだけで良いので、少量多品種に対しても柔軟に対応することが可能となる。   According to the first aspect of the present invention, a plurality of existing disc-shaped holding stands for constituting a heating coil unit of a standard electromagnetic induction heating cooker are used as they are, and are circulated between the holding stands. By winding the heating coil in this manner, a non-circular heating coil unit can be configured. For this reason, there is no need to provide a dedicated winding die or a bending roller, so that the heating coil unit can be manufactured at a low cost, and the diameter of the holding table is different even when the size of the heated surface is different. Since it is only necessary to change the diameter of the heating coil, it is possible to flexibly deal with a small variety of products.

また、請求項２の発明によれば、各保持台には加熱コイルの周回方向を横切るようにフェライトコアが配置されているので、加熱コイルのインダクタンス値を大きく設定することができ、高周波磁界中での表皮損失を低減して被加熱面を効率良く加熱することが可能となる。   According to the second aspect of the present invention, since the ferrite core is disposed so as to cross the rotating direction of the heating coil on each holding base, the inductance value of the heating coil can be set large, and the high frequency magnetic field can be set. It is possible to efficiently heat the surface to be heated by reducing the skin loss.

実施の形態１．
図１は本発明の実施の形態１における電磁誘導加熱調理器の加熱コイルユニットの平面図、図２は同加熱コイルユニットを構成するために使用する保持台の平面図である。 Embodiment 1 FIG.
FIG. 1 is a plan view of a heating coil unit of an electromagnetic induction heating cooker according to Embodiment 1 of the present invention, and FIG. 2 is a plan view of a holding table used to configure the heating coil unit.

この実施の形態１の電磁誘導加熱調理器の加熱コイルユニットは、２台分の保持台１を備え、各保持台１が金属板等でできた一枚の固定基板２上にボルト等によって取り付けられている。各保持台１は、図２に示すように、略円形の被加熱面を加熱するために製作された既存のものである。すなわち、各保持台１は、フェノール樹脂系などの絶縁性の耐熱樹脂成型品からなる円盤状をなし、中心部に表面側に突出した円形の突起１１が形成され、また、突起１１を中心に周方向に沿って扇形の切欠穴１２が所定のピッチで形成され、前後の各切欠穴１２の間にリブ１３が放射状に設けられている。   The heating coil unit of the electromagnetic induction heating cooker according to the first embodiment includes two holding bases 1 and each holding base 1 is attached to one fixed substrate 2 made of a metal plate or the like with a bolt or the like. It has been. As shown in FIG. 2, each holding stand 1 is an existing one that is manufactured to heat a substantially circular surface to be heated. That is, each holding stand 1 has a disk shape made of an insulating heat-resistant resin molded product such as a phenol resin, and a circular protrusion 11 protruding from the surface side is formed at the center, and the protrusion 11 is the center. Fan-shaped cutout holes 12 are formed at a predetermined pitch along the circumferential direction, and ribs 13 are provided radially between the front and rear cutout holes 12.

そして、各保持台１の突起１１に掛止された状態で各保持台１間を周回するように加熱コイル３が巻き付けられている。この加熱コイル３は、高周波域での表皮効果を低減させるリッツ線等からなる。なお、図示していないが、保持台１と加熱コイル３の間などには、加熱コイル３が位置ずれするのを防止するために接着固定用のシリコン樹脂が塗布されている。   And the heating coil 3 is wound so that it may circulate between each holding stand 1 in the state latched by the protrusion 11 of each holding stand 1. The heating coil 3 is made of a litz wire or the like that reduces the skin effect in the high frequency range. Although not shown, an adhesive fixing silicon resin is applied between the holding table 1 and the heating coil 3 in order to prevent the heating coil 3 from being displaced.

また、各保持台１のリブ１３には、平坦な棒状のフェライトコア４が接着等によって固定されている。この場合の各フェライトコア４は、加熱コイル３の周回方向を横切る位置に配置されている。このように、各保持台１に加熱コイル３の周回方向を横切るようにフェライトコア４を配置すれば、加熱コイル３のインダクタンス値を大きくすることができて高周波磁界中での表皮損失をさらに低減でき、被加熱面を効率良く加熱できるので都合が良い。   Further, a flat rod-shaped ferrite core 4 is fixed to the rib 13 of each holding table 1 by adhesion or the like. In this case, each ferrite core 4 is disposed at a position crossing the rotating direction of the heating coil 3. As described above, if the ferrite core 4 is arranged on each holding base 1 so as to cross the rotating direction of the heating coil 3, the inductance value of the heating coil 3 can be increased, and the skin loss in the high frequency magnetic field is further reduced. This is convenient because the surface to be heated can be heated efficiently.

上記構成の加熱コイルユニットを製作するには、まず、被加熱面の大きさを考慮した直径を有する２つの保持台１を準備する。そして、各保持台１の裏面側のリブ１３の箇所にフェライトコア４を接着等によって固定する。次に、各保持台１を固定基板２に図示しないボルト等によって固定した後、各保持台１の表面側の適宜箇所に加熱コイル３の接着固定用のシリコン樹脂を塗布する。そして、固定基板２と一つの保持台１との間に加熱コイル３の一端を差し込んで保持台１の一つの切欠穴１２から表面側に引き出し、各保持台１の突起１１に引掛けながら各保持台１間を周回するように加熱コイル３を順次巻き付ける。加熱コイル３の巻き付け後は、加熱コイル３の巻き付け位置が位置ずれしないように、その表面にシリコン樹脂を塗布して接着固定する。また、加熱コイル３の２つの各終端部も図示しない固定具により固定する。   In order to manufacture the heating coil unit having the above configuration, first, two holding bases 1 having a diameter in consideration of the size of the surface to be heated are prepared. And the ferrite core 4 is fixed to the location of the rib 13 of the back surface side of each holding stand 1 by adhesion or the like. Next, after each holding base 1 is fixed to the fixed substrate 2 with a bolt or the like (not shown), a silicon resin for bonding and fixing the heating coil 3 is applied to an appropriate portion on the surface side of each holding base 1. Then, one end of the heating coil 3 is inserted between the fixed substrate 2 and one holding table 1, pulled out from one notch hole 12 of the holding table 1 to the surface side, and hooked on the protrusion 11 of each holding table 1. The heating coil 3 is sequentially wound so as to circulate between the holding bases 1. After the heating coil 3 is wound, the surface of the heating coil 3 is coated and bonded and fixed so that the winding position of the heating coil 3 is not displaced. Further, the two end portions of the heating coil 3 are also fixed by a fixture (not shown).

以上のように、この実施の形態１では、標準的な電磁誘導加熱調理器の加熱コイルユニットを構成するための既存の２台の円盤状の保持台１をそのまま流用したかたちで、略長方形に周回された加熱コイル３を極めて容易に成型することができる。したがって、従来のような専用の巻き取り金型や屈曲用のローラを設ける必要がないので、略長方形の加熱コイルユニットを安価に製作することができ、しかも、被加熱面の大きさが大小異なる場合には、直径の異なる保持台１を使用するだけで良いので、少量多品種に対して柔軟に対応することが可能となる。   As described above, in the first embodiment, the two existing disk-shaped holding bases 1 for constituting a heating coil unit of a standard electromagnetic induction cooking device are used as they are, and are substantially rectangular. The circulating heating coil 3 can be molded very easily. Therefore, since there is no need to provide a dedicated winding die or bending roller as in the prior art, a substantially rectangular heating coil unit can be manufactured at a low cost, and the size of the surface to be heated is different in size. In this case, it is only necessary to use the holding bases 1 having different diameters, so that it is possible to flexibly cope with a small quantity and a wide variety.

なお、図１では、各保持台１の相互間の距離が短かい場合であるが、被加熱面の長手方向の寸法を大きくしたい場合には、図３に示すように、長手方向の寸法が大きい固定基板２を使用して２台の保持台１の相互間距離を長くし、巻き付けられる加熱コイル３の全長を長くすることで対処することが可能である。なお、この場合、左右の保持台１間に位置する加熱コイル３が位置ずれしないように、その中間部分を接着固定用のシリコン樹脂で確実に固定することが好ましい。また、直径の小さな既存の保持台１を使用すれば、被加熱面の短手方向の寸法を小さくすることが可能である。また、ここではフェライトコア４は平坦な棒状のものとしてリブ１３に固定しているが、その代わりにフェライトコア４を扇形に形成して切欠穴１２の内部に挿着することも可能である。   In FIG. 1, the distance between the holding bases 1 is short. However, when it is desired to increase the longitudinal dimension of the heated surface, the longitudinal dimension is as shown in FIG. This can be dealt with by using a large fixed substrate 2 to increase the distance between the two holding bases 1 and to increase the total length of the heating coil 3 to be wound. In this case, it is preferable to securely fix the intermediate portion with a silicon resin for adhesive fixing so that the heating coil 3 positioned between the left and right holding bases 1 is not displaced. Moreover, if the existing holding stand 1 with a small diameter is used, it is possible to reduce the dimension in the short direction of the heated surface. Further, here, the ferrite core 4 is fixed to the rib 13 as a flat bar, but instead, the ferrite core 4 may be formed in a sector shape and inserted into the notch hole 12.

実施の形態２．
図４はこの実施の形態２における電磁誘導加熱調理器の加熱コイルユニットの平面図である。 Embodiment 2. FIG.
FIG. 4 is a plan view of a heating coil unit of the electromagnetic induction heating cooker according to the second embodiment.

実施の形態１では、加熱コイル３は２つの保持台１間にわたって稠密に巻き付けられているが、この実施の形態２では、各保持台１には中心の突起１１に加えて、さらに２つの突片１４が設けられており、これらの各突片１４によって周回される加熱コイル３間に所定の隙間Ｓｐが生じるように構成されている。   In the first embodiment, the heating coil 3 is tightly wound between the two holding bases 1, but in this second embodiment, each holding base 1 has two protrusions in addition to the central protrusion 11. A piece 14 is provided, and a predetermined gap Sp is formed between the heating coils 3 that are circulated by the protrusions 14.

このように、各保持台１に突片１４を設けることにより周回される加熱コイル３に隙間Ｓｐを生じるようにすれば、加熱コイル３を２つの保持台１間にわたって稠密に巻き付ける場合に比べて、電磁誘導加熱調理器に要求される加熱特性に応じて加熱コイル３のインダクタンス値を任意に調整できる利点が得られる。   As described above, if the gap Sp is generated in the heating coil 3 that is circulated by providing the projecting piece 14 on each holding base 1, compared to the case where the heating coil 3 is densely wound between the two holding bases 1. And the advantage which can adjust the inductance value of the heating coil 3 arbitrarily according to the heating characteristic requested | required of an electromagnetic induction heating cooking appliance is acquired.

実施の形態３．
図５はこの実施の形態３における電磁誘導加熱調理器の加熱コイルユニットの平面図である。 Embodiment 3 FIG.
FIG. 5 is a plan view of the heating coil unit of the electromagnetic induction heating cooker according to the third embodiment.

実施の形態１，２では、２台の保持台１を使用して略長方形の加熱コイルユニットを構成しているが、この実施の形態３では４台の保持台１を使用して略正方形の加熱コイルユニットを構成している。すなわち、正方形の固定基板２の４隅にそれぞれ保持台１を固定し、各保持台１間を周回するように加熱コイル３が巻き付けられている。   In the first and second embodiments, the two holding tables 1 are used to form a substantially rectangular heating coil unit. In the third embodiment, four holding tables 1 are used to form a substantially square shape. A heating coil unit is configured. That is, the holding table 1 is fixed to each of the four corners of the square fixed substrate 2, and the heating coil 3 is wound around the holding table 1.

このように、４台の保持台１を使用すれば略正方形の加熱コイルユニットを構成できるので、加熱コイルユニットの形状が長方形のものに限定されなくなり、応用面が広がる。   As described above, when the four holding bases 1 are used, a substantially square heating coil unit can be configured. Therefore, the shape of the heating coil unit is not limited to the rectangular shape, and the application surface is expanded.

なお、図５に示す構成の場合、加熱コイル３で囲まれた内側部分は加熱が不均一になる恐れがある。これに対処するには、図６に示すように、固定基板２上の４台の保持台１の取り付け位置よりも内側にそれぞれ突起２１を設け、各突起２１の外側を周回するように加熱コイル３を巻き付けた後、引き続いて、この加熱コイル３を保持台１の突起１１の外側を周回するように加熱コイル３を巻き付ける。これにより、保持台１の突起１１よりも内側の部分も同時に加熱できるので、加熱の不均一さを解消することができる。なお、固定基板２の突起２１に沿って巻き付ける加熱コイルと、各保持台１の突起１１に沿って巻き付ける加熱コイルとを別体のものとすることも可能である。   In the case of the configuration shown in FIG. 5, the inner portion surrounded by the heating coil 3 may be non-uniformly heated. In order to cope with this, as shown in FIG. 6, the projections 21 are provided on the inner side of the mounting positions of the four holding bases 1 on the fixed substrate 2, and the heating coils are circulated around the outer sides of the projections 21. After winding 3, the heating coil 3 is subsequently wound around the outside of the protrusion 11 of the holding table 1. Thereby, since the part inside the processus | protrusion 11 of the holding stand 1 can also be heated simultaneously, the nonuniformity of a heating can be eliminated. Note that the heating coil wound along the protrusions 21 of the fixed substrate 2 and the heating coil wound along the protrusions 11 of each holding base 1 can be separated.

本発明は上記の実施の形態の構成に限定されるものではなく、その趣旨を逸脱しない範囲内において各種の変形を加えることができる。例えば、実施の形態１，２では２台の保持台１を使用して長方形の加熱コイルユニットを、また実施の形態３では４台の保持台１を使用して正方形の加熱コイルユニットをそれぞれ構成したが、これに限らず、例えば３台の保持台１を使用して略三角形の加熱コイルユニットを構成したり、６台の保持台１を使用したり、８台の保持台１を使用したりして多角形の加熱コイルユニットを構成することも可能である。   The present invention is not limited to the configuration of the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the first and second embodiments, two holding bases 1 are used to form a rectangular heating coil unit, and in the third embodiment, four holding bases 1 are used to form a square heating coil unit. However, the present invention is not limited to this. For example, a substantially triangular heating coil unit is configured using three holding bases 1, six holding bases 1 are used, or eight holding bases 1 are used. It is also possible to configure a polygonal heating coil unit.
