産業上の利用分野
本発明は一般家庭において使用される電気炊飯器等の鍋
を用いる電気調理器の加熱装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating device for an electric cooker using a pot, such as an electric rice cooker, used in general households.
従来の技術
従来、この種の電気調理器の加熱装置は、例えば第4図
に示すような構造になっていた。BACKGROUND ART Conventionally, a heating device for an electric cooker of this type has a structure as shown in FIG. 4, for example.
すなわち、本体1内において、シーズヒーター2をアル
ミで鋳込み、天面を球面状に形成した鋳込みヒーター3
上に、底面が鋳込みヒーター3の球面とほぼ同一の球面
形状を有するjA4を直接載置し、鋳込みヒーター3に
よって鍋4内の調理物を加熱調理するようになっていた
。That is, in the main body 1, a sheathed heater 2 is cast from aluminum, and a cast-in heater 3 whose top surface is formed into a spherical shape is installed.
A jA4 whose bottom surface has a spherical shape almost the same as that of the cast-in heater 3 is placed directly on top, and the food in the pot 4 is heated and cooked by the cast-in heater 3.
発明が解決しようとする課題
しかし、このような構造のものでは、鋳込みヒーター3
0球面と、鍋4の底面の球面とは、はぼ同一にしている
が、加工バラツキや、熱時の変形等により、球面全面で
接触することは不可能であり、実際には、3点接触とな
るため、接触部からの熱の供給が多く、特に炊飯等を行
なった場合、接触部上が吸熱が多すぎるため米が軟化し
、その他の部分が吸熱が悪く、炊き不足のため硬くなっ
たりして、炊きむらが非常に多いものであった。Problems to be Solved by the Invention However, with such a structure, the cast-in heater 3
The 0 spherical surface and the spherical surface of the bottom of the pot 4 are almost the same, but due to variations in processing and deformation during heating, it is impossible to make contact over the entire spherical surface, so in reality, three points are used. Because of the contact, a large amount of heat is supplied from the contact area.Especially when cooking rice, the rice absorbs too much heat on the contact area and becomes soft, while other areas absorb heat poorly and become hard due to insufficient cooking. As a result, the cooking was very uneven.
また、例えば米粒等の異物が鋳込みヒーター3上に載置
された状態で鍋4をセットした場合、鋳込みヒーター3
と鍋4の接触はさらに悪(なるため、調理の加熱ムラは
より悪いものとなり、かつ、鋳込みヒーター3からの熱
供給と、鍋4の吸熱のバランスが(ずれて、鋳込みヒー
ター3は極部的に空焼き状態となって高温となるために
、変形等の危険性が非常に大きいものであった。Furthermore, if the pot 4 is set with a foreign object such as rice grains placed on the casting heater 3, the casting heater 3
The contact between the pot 4 and the pot 4 becomes worse (this makes the heating unevenness of cooking worse), and the balance between the heat supply from the cast-in heater 3 and the heat absorption of the pot 4 is shifted, and the cast-in heater 3 Because the temperature is high due to dry firing, there is a very high risk of deformation.
また、シーズヒーターを略円周状に巻き加工して加熱装

ターがフラットな面がないため、異物がヒーターの隙間
から下へ落下し、掃除もしに(いものであった。さらに
、空間層を設けて加熱しているため熱効率が悪く、鍋の
上方まで均一に加熱するのが困難であった。In addition, there are cases where the sheathed heater is wound into a substantially circumferential shape to be used as a heating device, and a space layer is provided between the pot and the sheathed heater for cooking, but in this case, the sheathed heater alone is exposed. It had a bad appearance, and since the heater did not have a flat surface, foreign matter fell down through the gaps in the heater, making it difficult to clean.Furthermore, a space layer was provided to heat the heater. Therefore, the heat efficiency was poor, and it was difficult to heat the pot evenly to the top.
そこで本発明は、加熱ムラが非常に少なく、異物のはさ
み込みによる異常加熱を防止し、なおかつ外観的に良好
で掃除性も良い電気調理器の加熱装置を得ることを第1
の目的としている。Therefore, the first object of the present invention is to provide a heating device for an electric cooker that has very little heating unevenness, prevents abnormal heating due to foreign matter, and has a good appearance and is easy to clean.
The purpose is to
第2の目的は、鍋の外周上方まで効率良く熱を伝達し、
加熱面積の向上と、より一層の加熱ムラの向上を得るこ
とにある。The second purpose is to efficiently transfer heat to the upper part of the outer periphery of the pot.
The objective is to improve the heating area and further improve heating unevenness.

したものである。In addition, in order to achieve the second object, the present invention provides a heat insulating base having a substantially bowl-shaped cross section having substantially the same shape as the top plate, and grooves in which the heating wires are disposed are formed in a spiral shape with substantially the same depth. It is configured by providing the following.
作用
本発明の電気調理器の加熱装置は、上記構成により鍋と
天板がほぼ同一形状であり、かつ天板の外周が上方へ凸
形状の略碗形状のため、鍋の底部及び側部から熱の供給
が行なわれる。Function The heating device for an electric cooker of the present invention has the above-mentioned configuration, so that the pot and the top plate have almost the same shape, and the top plate has an upwardly convex outer periphery that is approximately bowl-shaped. Heat is supplied.
また、アルミ等の低融点材料を使用していないため、耐
熱性が強く、さらに腕形状のため熱変形に対しても強い
ものである。Furthermore, since it does not use low-melting point materials such as aluminum, it has strong heat resistance, and its arm shape also makes it resistant to thermal deformation.
このことから、鍋と天板とは直接接触させる必要もなく
、鍋への均一加熱が可能であり、加熱ムラを低減できる
こととなる。また、鍋と天板との間に空間層を設けるこ
とによって、異物等が天板上に落下しても、通常の調理
での加熱ムラに対して何ら影響を与えない。さらに天板
が金属板で形成されているため外観的にも良好であり、
掃除性も良いものである。Therefore, there is no need for direct contact between the pot and the top plate, and uniform heating of the pot is possible, reducing uneven heating. Further, by providing a space layer between the pot and the top plate, even if foreign objects or the like fall onto the top plate, it will not have any effect on uneven heating during normal cooking. Furthermore, since the top plate is made of metal plate, it has a good appearance.
It is also easy to clean.
また、断熱基盤を天板とほぼ同形状の断面略碗形状に形

る。In the above configuration, when the heating wire 13 is energized, the heat insulating base 11
.. Top plate 10. The storage case 14 is heated to bring the heater unit 10a into a high temperature state. At this time, since a high temperature heat resistant material is used and the heating wire 13 can be kept energized in a high temperature state, the heater unit 10a immediately reaches a high temperature state and begins to radiate heat. In addition, since the top plate 10 has a substantially bowl-shaped cross section and the heat insulating base 11 has a disk shape, there is a space layer between the convex portion near the outer periphery of the top plate 10 and the heat insulating base 11.
Since the top plate 10 and the storage case 14 are joined in a substantially closed manner, the space layer is rapidly heated and becomes a high temperature atmosphere. Therefore, the temperature distribution of the top plate 10 approaches a substantially uniform state, so that heat can be supplied to the pot 15 from the bottom and sides, uniform heating can be performed, and uneven heating can be prevented. In particular, when cooking rice, etc., there is a space layer between the pot 15 and the top plate 1o, so there is no excessive supply of heat locally (as mentioned above, the temperature distribution of the top plate 10 is also good, so Extremely uneven cooking can be prevented.Also, even if rice is cooked with a foreign object falling onto the top plate 1o, since there is a space layer between the top plate 10 and the pot 15, uneven cooking can be prevented. There is almost no negative effect on cooking performance such as an increase in heat.Furthermore, since the top plate 10 is drawn to have a roughly bowl-shaped cross section, it is resistant to thermal deformation at high temperatures (
Since the surface is smooth, the appearance quality and cleanability are good.

鍋15への熱供給がより均一化され、鍋15の側部への
熱供給もより確実に行なわれるため、調理の加熱もより
一層均−となり、また加熱効率の向上も望めるものであ
る。In this embodiment, the heat insulating base 24 is housed in substantially the same shape as the back surface of the top plate 10, and the heating wires 13 are also located at substantially the same depth along the top shape of the heat insulating base 24. The outer peripheral convex portion of the top plate 10 is also heated evenly, and
The temperature rise time is also faster. Therefore, compared to the first embodiment, the heat supply to the pot 15 is made more uniform, and the heat supply to the sides of the pot 15 is also more reliably carried out, so that the cooking heating becomes even more uniform and the heating efficiency is improved. There is hope for improvement.
