Description
【０００１】[0001]
この考案は、電気炊飯器等の調理器の加熱装置に関するものである。 The present invention relates to a heating device for a cooking device such as an electric rice cooker.
【０００２】[0002]
業務用の電気炊飯器のように大形の調理器の加熱装置は十分大きな電力を必要 とするため、シーズヒータを渦巻き形に２〜３周巻き曲げたものが使用される。 Since a heating device for a large-sized cooker such as an electric rice cooker for business use requires a sufficiently large amount of electric power, a sheathed heater wound in a spiral shape for a few turns is used.
【０００３】 この場合の渦巻き形シーズヒータは、その内端から外端まで、中心からの半径 が角度に応じて滑らかに増大する形状、即ち正規の渦巻き形状をなし、また、全 体として平盤形のものであった。The spiral sheathed heater in this case has a shape in which the radius from the center smoothly increases in accordance with the angle from the inner end to the outer end, that is, a regular spiral shape, and as a whole, it is a flat plate. It was in shape.
【０００４】[0004]
しかしながら、上記のごとき渦巻き形シーズヒータを用いて炊飯等の調理を行 った場合、シーズヒータの内端や外端の近傍において火力が不足しがちであり、 調理物の仕上がりにムラがあるという問題があった。 However, when cooking rice etc. using the spiral sheathed heater as described above, the heating power tends to be insufficient near the inner end and the outer end of the sheathed heater, and the finish of the cooked product is uneven. There was a problem.
【０００５】 一方、調理鍋の底面は、プレス成形の都合上、中央部分が内方に高く、外方に 至るに従って低くなる曲面になっているが、これを加熱するためのシーズヒータ は全体として平盤形であるので、鍋の底面とシーズヒータの間隙が不均一であっ た。その不均一の影響を無くするため、従来は、遮熱板に工夫を加えたり、或い は熱風を循環させるなどして均一な加熱が出来るようにしていたが、このような 手段は製品のコストアップの要因になるという難点があった。On the other hand, the bottom surface of the cooking pot has a curved surface in which the central portion is higher inwardly and lowers outwardly for the convenience of press molding, but the sheathed heater for heating this is generally Because of the flat plate shape, the gap between the bottom of the pan and the sheathed heater was uneven. In order to eliminate the influence of the non-uniformity, conventionally, a heat shield plate was devised, or hot air was circulated so that uniform heating could be performed. There was a drawback that it would increase the cost.
【０００６】 そこで、この考案の課題はシーズヒータの形状に工夫を加えることにより、上 述の問題を解決することである。Then, the subject of this invention is to solve the above-mentioned problem by adding a device to the shape of the sheathed heater.
【０００７】[0007]
【課題を解決するための手段】 上記の課題を解決するための第１の手段は、渦巻き形シーズヒータを有する調 理器の加熱装置において、上記シーズヒータ内端の反渦巻き方向に片寄った部分 に正規の渦巻き形状より内側に寄った内側片寄り部を形成し、ヒータ外端の渦巻 き方向に片寄った部分に正規の渦巻き形状より外側に寄った外側片寄り部を形成 した構成としたものである。[Means for Solving the Problems] A first means for solving the above problems is, in a heating device for a controller having a spiral sheathed heater, a portion of the inner end of the sheathed heater which is offset in the anti-spiral direction. The inner side of the regular spiral shape is formed on the inner side of the heater, and the outer side of the heater is formed on the outer side of the regular spiral shape. Is.
【０００８】 また、第２の手段は、上記第１の手段の構成において、底面の中心部分が内方 に高く、外周に至るほど低くなる曲面に形成された鍋を載せる加熱装置において 、内側のシーズヒータに比べ外側のシーズヒータが上記鍋の底面形状に沿って低 く形成された構成としたものである。The second means is the same as the first means, in the heating device for placing a pan formed on a curved surface in which the central portion of the bottom surface is inwardly high and becomes lower toward the outer circumference, The outer sheath heater is lower than the sheath heater along the bottom shape of the pot.
【０００９】[0009]
上記第１の手段の加熱装置においては、火力の不足する部分にシーズヒータが 片寄って配置されるので、その部分の火力が上昇し、全体として火力分布が均一 化する。 In the heating device of the first means, since the sheathed heater is arranged offset to the portion where the thermal power is insufficient, the thermal power of that portion rises and the thermal power distribution becomes uniform as a whole.
【００１０】 また、第２の手段の加熱装置においては、シーズヒータと鍋の底面間の間隙が 全体的に均一化されるので、火力分布が一層均一化される。Further, in the heating device of the second means, the gap between the sheath heater and the bottom surface of the pan is made uniform as a whole, so that the heat power distribution is made more uniform.
【００１１】[0011]
添付の図面は、調理器の一例としての電気炊飯器の加熱装置を示すものである 。 The attached drawings show a heating device of an electric rice cooker as an example of a cooker.
【００１２】 図１において、１は胴、２は底、３は蓋、４は外遮熱板、５は外容器、６は鍋 、７は加熱装置、８は温度センサを示す。また図２において、９は肩、１１は外 容器５と加熱装置７との間に介在された内遮熱板である。この内遮熱板１１は中 央部分にテーパ状の立上がり部１２があり、その立上がり部１２に温度センサ８ を臨ませるための穴１４が形成される（図４参照）。In FIG. 1, 1 is a body, 2 is a bottom, 3 is a lid, 4 is an outer heat shield plate, 5 is an outer container, 6 is a pot, 7 is a heating device, and 8 is a temperature sensor. Further, in FIG. 2, 9 is a shoulder, and 11 is an inner heat shield plate interposed between the outer container 5 and the heating device 7. The inner heat shield plate 11 has a tapered rising portion 12 in the center thereof, and a hole 14 for allowing the temperature sensor 8 to face is formed in the rising portion 12 (see FIG. 4).
【００１３】 加熱装置７は、渦巻き形のシーズヒータ１５により構成される。このシーズヒ ータ１５は、内遮熱板１１の立上がり部１２に近い部分に形成された穴を通して 内遮熱板１１の上面に引出される。シーズヒータ１５はこの引出された端部、即 ち内端１６を基点として、立上がり部１２のまわりを囲み、次第に中心からの距 離が大きくなって渦巻き形をなす。渦巻き形に２周半回ったところで、シーズヒ ータ１５の端部、即ち外端１７は、内遮熱板１１の穴からその下面に引込まれ、 その下面においてリード線と接続される。The heating device 7 is composed of a spiral sheathed heater 15. The sheath heater 15 is drawn out to the upper surface of the inner heat shield plate 11 through a hole formed in a portion of the inner heat shield plate 11 near the rising portion 12. The sheathed heater 15 surrounds the rising portion 12 with the pulled-out end portion, i.e., the inner end 16 as a base point, and the distance from the center gradually increases to form a spiral shape. After two and a half turns in a spiral shape, the end of the sheath heater 15, that is, the outer end 17, is drawn from the hole of the inner heat shield plate 11 to the lower surface thereof, and is connected to the lead wire at the lower surface.
【００１４】 上記のシーズヒータ１５は、３箇所において、ホルダ１８、１９、２０により 支持され、内遮熱板１１上から所定の間隔を保持している。１つのホルダ１８は 内端１６の近くに設けられ、他の２つのホルダ１９、２０は上記のホルダ１８か ら中心角で１２０度ずつ隔てた位置において放射方向に設けられる。The sheathed heater 15 is supported by holders 18, 19 and 20 at three locations and holds a predetermined space above the inner heat shield plate 11. One holder 18 is provided in the vicinity of the inner end 16, and the other two holders 19 and 20 are provided in the radial direction at positions separated from the holder 18 by 120 degrees in central angle.
【００１５】 これらのホルダ１８、１９、２０は、図４に示すように、外容器５の底面に固 定された下ホルダ２１を内遮熱板１１の放射方向のスリット２２に挿入し、その 下ホルダ２１によりシーズヒータ１５の下面を支持する。シーズヒータ１５の上 面は上ホルダ２３により保持され、上ホルダ２３は下ホルダ２１上に重ねて内遮 熱板１１に固定される。As shown in FIG. 4, these holders 18, 19 and 20 are obtained by inserting a lower holder 21 fixed to the bottom surface of the outer container 5 into a radial slit 22 of the inner heat shield plate 11. The lower holder 21 supports the lower surface of the sheath heater 15. The upper surface of the sheath heater 15 is held by the upper holder 23, and the upper holder 23 is stacked on the lower holder 21 and fixed to the inner heat shield plate 11.
【００１６】 シーズヒータ１５の渦巻き形状は正規の渦巻き形状（図３の二点鎖線参照）か ら部分的にずれている。即ち、内端１６の近傍においては、その内端１６近くの ホルダ１８から反渦巻き方向の隣接したホルダ２０との間において、１周目のシ ーズヒータ１５が正規の渦巻き形状から内方へ片寄った内側片寄り部２４が形成 され、上記二つのホルダー１８、２０間における立上がり部分１２に沿った部分 の火力分布の不足を補っている。The spiral shape of the sheath heater 15 is partially deviated from the regular spiral shape (see the chain double-dashed line in FIG. 3). That is, in the vicinity of the inner end 16, between the holder 18 near the inner end 16 and the adjacent holder 20 in the anti-spiral direction, the sheath heater 15 on the first turn is deviated inward from the regular spiral shape. An inner offset portion 24 is formed to compensate for the lack of thermal power distribution in the portion along the rising portion 12 between the two holders 18 and 20.
【００１７】 また、上記内端１６の近傍のホルダ１８から反渦巻き方向に二つ目のホルダ１ ９にわたる範囲のシーズヒータ１５については、正規の渦巻き形状よりも外方へ 片寄った外側片寄り部２５が形成されており、この部分の火力分布の不足を補っ ている。Further, regarding the sheathed heater 15 in the range extending from the holder 18 near the inner end 16 to the second holder 19 in the anti-spiral direction, the outer side offset portion which is offset outward from the regular spiral shape. 25 is formed, which compensates for the lack of thermal power distribution in this part.
【００１８】 一方、前記の鍋６の底面は、中央部分が最も高く、外周に至るに従い、緩やか に低くなる曲面に形成されている。前記のシーズヒータ１５はその鍋６の底面の 曲面に沿って、その中央部分、即ち内遮熱板１１の立上がり部分１２の周りの１ 周目の部分が最も高く、２周目以降は次第に低くなるように形成され、全体とし て、鍋６の底面とシーズヒータ１５との間隔は一定に保持される。On the other hand, the bottom surface of the pot 6 is formed to have a curved surface that is highest at the central portion and gradually lowers toward the outer circumference. The sheath heater 15 has the highest center portion along the curved surface of the bottom surface of the pot 6, that is, the first lap portion around the rising portion 12 of the inner heat shield plate 11, and gradually lowers after the second lap. The bottom surface of the pot 6 and the sheath heater 15 are maintained at a constant distance as a whole.
【００１９】[0019]
以上のように、この考案によればシーズヒータが内端及び外端の近傍において それぞれ内側片寄り部及び外側片寄り部を有することから、平面的な火力分布が 均一化され調理の仕上がりが良好である。 As described above, according to the present invention, since the sheathed heater has the inner offset portion and the outer offset portion in the vicinity of the inner end and the outer end, respectively, the planar heating power distribution is made uniform and the cooking finish is good. Is.
【００２０】 更に、上記の構成に加えて鍋底の曲面形状に沿うより中央部が高く、外周に至 るほど低くなるよう形成することにより、鍋底とシーズヒータとの間隔が一定と なり、一層火力分布の均一化が促進され、調理の仕上りも一層良好となる。Further, in addition to the above-mentioned configuration, by forming so that the central portion is higher than the curved shape of the pan bottom and becomes lower toward the outer circumference, the interval between the pan bottom and the sheath heater becomes constant, and the thermal power is further improved. Uniform distribution is promoted, and the finish of cooking is further improved.
【００２１】 また、シーズヒータの形状の工夫だけで火力分布の均一化を図ることができ、 他の部材を用いる必要がないので、低コストである利点もある。Further, it is possible to make the thermal power distribution uniform only by devising the shape of the sheathed heater, and it is not necessary to use other members, so that there is also an advantage of low cost.
