【発明の詳細な説明】 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。TECHNICAL FIELD The present invention relates to a heating device for an electric cooker using a pot such as an electric rice cooker used in a general household.
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。2. Description of the Related Art Conventionally, a heating device of this kind of electric cooker 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
形状を有する鍋４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, the sheathed heater 2 is casted of aluminum, and the top surface of the casted heater 3 is spherical.
The pot 4 having a spherical surface whose bottom surface is almost the same as the spherical surface of the casting heater 3 is directly placed on the top, and the food in the pot 4 is cooked by the casting 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
の球面と、鍋４の底面の球面とは、ほぼ同一にしている
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。However, in the case of such a structure, the casting heater 3
The spherical surface of the pan and the spherical surface of the bottom surface of the pot 4 are almost the same, but it is impossible to make contact on the entire spherical surface due to variations in processing, deformation during heating, etc. Therefore, the amount of heat supplied from the contact part is large, especially when rice is cooked, the contact part has too much heat absorption to soften the rice, and the other parts have poor heat absorption and become hard due to insufficient cooking. However, there was a lot of uneven cooking.
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の接触はさらに悪くなるため、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くずれて、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。In addition, when the pot 4 is set with foreign matter such as rice grains placed on the pouring heater 3, the pouring heater 3
Since the contact between the pot 4 and the pot 4 becomes even worse, the heating unevenness in cooking becomes worse, and the balance between the heat supply from the casting heater 3 and the endothermic heat of the pot 4 is disturbed, and the casting heater 3 is extremely localized. Since it is in an air-baked state and has a high temperature, the risk of deformation and the like is extremely great.

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 is a case where a sheath heater is wound in a substantially circular shape to form a heating device, and a space layer is provided between the pot and the sheath heater for cooking, but in this case, the sheath heater alone is exposed. The appearance was poor, and since the heater did not have a flat surface, foreign matter fell down through the gap between the heaters, making cleaning difficult. Further, since the heating is performed by providing the space layer, the thermal efficiency is poor, and it is difficult to uniformly heat the upper part of the pot.
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 obtain a heating device for an electric cooker in which uneven heating is extremely small, abnormal heating due to entrapment of foreign matter is prevented, and the appearance is good and the cleaning property is good.
The purpose is.
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 circumference of the pot,
It is to obtain an improved heating area and further improved heating unevenness.

が行なわれる。Effect The heating device of the electric cooker of the present invention has the pot and the top plate having substantially the same shape due to the above-mentioned configuration, and the outer periphery of the top plate has a substantially bowl-like shape that is convex upward, so that the bottom and side portions of the pan 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、さらに碗形状のため熱変形に対しても強い
ものである。In addition, since it does not use a low melting point material such as aluminum, it has high heat resistance, and since it is bowl-shaped, it is also 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

め外観的にも良好であり、掃除性も良いものである。From this, it is possible to uniformly heat the pot without having to make direct contact between the pot and the top plate and reduce uneven heating. Further, by providing a predetermined space layer over the entire range between the pan and the top plate, even if a foreign substance or the like falls on the top plate, it does not have any influence on uneven heating in normal cooking. Further, since the top plate is made of a metal plate, it has a good appearance and is easy to clean.

好である。In the above configuration, when the heating wire 13 is energized, the heat insulating substrate 11, the top plate 10 and the storage case 14 are heated, and the heater unit 10a is brought into a high temperature state. At this time, using high temperature heat resistant material,
Since the heating wire 13 can be kept energized at a high temperature, the heater unit 10a immediately becomes a high temperature and radiates heat. In addition, the top plate 10 has a substantially bowl-shaped cross section and has a heat insulating base 11
Since it is 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, but since the top plate 10 and the storage case 14 are almost closed and joined, The space layer is rapidly heated to 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 side portions to perform uniform heating and prevent uneven heating. Especially when cooking rice etc., pan 15 and the top plate
Since there is a specified space layer over the entire area between 10 and 10, there is no excessive supply of heat locally, and as mentioned above, the top plate 10
Since the temperature distribution is good, it is possible to prevent uneven cooking unevenness. Even if rice is cooked with foreign matter falling on the top plate 10, a predetermined space layer is provided between the top plate 10 and the pan 15 over the entire range, so that cooking unevenness is increased. There is almost no adverse effect on performance. Further, since the top plate 10 is drawn into a substantially bowl-shaped cross-section, it is resistant to thermal deformation at high temperatures, and the surface is smooth, so the appearance quality and cleanability are good.

Since they are located at almost the same depth along the top surface shape of
The convex portion on the outer periphery of the top plate 10 is evenly heated, and the temperature rise time is shortened. Therefore, the heat supply to the pan 15 is made more uniform than in the first embodiment, and the heat is supplied to the side portions of the pan 15 more reliably, so that the heating of cooking becomes more uniform and the heating efficiency is improved. Can be expected.
