【発明の属する技術分野】
本発明はコンロ部に備えた赤外線を放射するランプヒータにて直上の耐熱ガラスを介して被加熱物を加熱するものにおいて、耐熱ガラスの下部に備えた温度センサにて被加熱物の温度制御をするもので、ひとつの温度センサにて四つの加熱機能を適正加熱制御する加熱調理器に関するものである。
【0002】
【従来の技術】
従来この種の加熱調理器としては特開平4−236016号公報がある。その構成について図7を参照しながら説明する。
【0003】
従来は耐熱ガラス2の下部に備えた温度センサ5にて被加熱物1の温度制御するもので
、コンロ部3を断熱材構成とし前記温度センサ5にランプヒータ4よりの熱をバイアスとして付加し加熱制御するものである。
【0004】
つまり、被加熱物1が載置されている耐熱ガラス2の下部にコンロ部3を備え、前記コンロ部3にはランプヒータ4と前記耐熱ガラス2の下部に当接した温度センサ5が内蔵されている。また、前記コンロ部3は上部を開口し側面と底面を備えた垂直断面が皿状とし前記耐熱ガラス2の直下にてスプリングバネにて6にて当接したもので、外壁7を金属材とし前記外壁7の内面に沿ってリング状の断熱材A8とドーナツ状の断熱材B9を備えるとともに前記外壁7の中央部に円筒状部10を備えている。さらに、前記円筒状部10の内側(ランプヒータ側)にリング状の断熱材C11を備えるとともに前記断熱材C11の上面に断熱材D12を備え前記耐熱ガラス2と断熱材C11にて隙間を無くしたものである。
【0005】
上記構成により加熱を開始するとコンロ部3内部のランプヒータ4が発熱し直上部の耐熱ガラス2を透過し被加熱物1を伝導とふく射により加熱することになる。具体例として揚げ物加熱の場合について述べると、温度センサ5に対してはランプヒータ4よりの輻射熱の大半を三種類の断熱材にて遮っているものの、少々の熱をバイアスとして付加し前記被加熱物1の油の温度上昇勾配と前記温度センサ5の温度上昇勾配を近似(応答時間の遅れを少なくした)したものである。
【0006】
これにより、揚げ物加熱時に油の発火を防止するために温度センサ5にて加熱制御をするもので、温度センサ5にて予め制御部に入力しておいた温度に到達するとコンロ部3のランプヒータ4を自動停止し油の発火を防止し安全を確保するものである。
【0007】
【発明が解決しようとする課題】
しかしながら、図7で示した上記従来の加熱調理器の加熱制御ではひとつの温度センサにて揚げ物の時の過熱防止のための加熱制御ができるものの、揚げ物以外の焼き物、鍋物、保温など多機能の加熱制御ができないものである。
【0008】
何故なら、揚げ物、焼き物、鍋物、保温の加熱制御をするにはそれぞれに最適温度の設定と最適な制御が必要となる。例えば、揚げ物のときの油の発火を防止するための温度設定と加熱制御は前記までに明らかであるが、焼き物のときの被加熱物としてのフッ素コーティングした焼き肉プレート、フライパンなどの過熱を防止するための温度設定と加熱制御、鍋物のとき、とくに土鍋の場合には加熱性能を良くするためにパワーをUPするか耐熱ガラス2の温度を少しでも高くするためと空焚きを防止するための温度設定と加熱制御、さらに、コーヒーサーバなどの保温およびシチューなどの加熱後の保温などの加熱制御などのことを設定しなければならない課題があった。
【0009】
【課題を解決するための手段】
本発明は上記課題を解決するために、コンロ部に備えた赤外線を放射するランプヒータにて直上の耐熱ガラスを介して被加熱物を加熱し耐熱ガラスの下部に備えた温度センサにて被加熱物の加熱制御をするもので、ひとつの温度センサにて四つの機能を加熱制御するようにした。
【0010】
上記発明によれば、加熱調理器として揚げ物、焼き物、鍋物、保温など多機能の加熱ができ、且つ安全および最適加熱ができるために使い勝手がよい。
【0011】
【発明の実施の形態】
本発明は、被加熱物を載置する耐熱ガラスと前記耐熱ガラスの下部に加熱手段を内蔵したコンロ部とを備え、前記コンロ部に前記耐熱ガラスに当接し前記被加熱物を加熱制御す

【0012】
そして、簡単な構成にて揚げ物、焼き肉、鍋物、および保温の四つの機能を適正に加熱制御ができ使い勝手がよい。
【0013】
また、ひとつの温度センサにて四つの機能を制御するもので、揚げ物キー加熱のときは予め制御部に入力しておいた温度を260℃前後としこの温度以上にて加熱手段を自動停止、焼き物キーのときは予め制御部に入力しておいた温度を230℃前後としこの温度以上にて加熱手段のパワーを自動的にダウンし設定温度未満にて自動的にフルパワーに戻すとともに、鍋物キー加熱のときは予制御部に入力しておいた温度を330℃前後としこの温度以上にて加熱手段を自動停止、保温キーのときは予め制御部に入力しておいた温度を80℃前後とし設定温度以上にて加熱手段のパワーをOFFし設定温度未満にて自動的にパワーONする制御とした構成のもの。
【0014】
そして、揚げ物加熱時に油の発火を防止することができるために安全であるとともに、フッ素コーティングの処理をした焼き肉プレートの適正加熱、土鍋加熱の場合の加熱性能が良い。さらに、食器保温、調理保温ができ大変便利である。
【0015】
また、アルミニウムにて形成したコンロ部と板厚が4mm程度の耐熱ガラスに当接し被加熱物を加熱制御する温度センサを備えたもので、保温キー加熱のとき耐熱ガラスの温度を110℃〜130℃の略一定になるように、パワーをフルパワーより相当小さく(例えば、60W〜80W)する構成としたもの。
【0016】
そして、パワーを60W〜80Wにて耐熱ガラス2の温度を略一定(110℃〜130℃)にしているために、保温後に耐熱ガラス2に触れても火傷しにくい温度であり安全と保温を両立したものである。また、調理保温(例えば、カレー、シチュー)において省エネ保温ができる。
【0017】
【実施例】
以下、本発明の一実施例について図面を用いて説明する。
【0018】
(実施例1)
図1は本発明の実施例1の加熱調理器の外観図である。また図2は同加熱調理器の断面図である。また図3は同加熱調理器のコンロ部の外観図である。また図4は同加熱調理器の操作部の図である。また図5は同加熱調理器の制御ブロック図である。
【0019】
ひとつの温度センサ5にて揚げ物、焼き肉、鍋物、および保温の四つの機能を加熱制御するものである。
【0020】
図1から図5において、被加熱物1を載置し赤外線を透過する耐熱ガラス2は上面ケース13と接着剤14にて一体化するとともに、コンロ部3と冷却ファン15を内蔵した下面ケース16とはねじ17にて固定し結合したものである。
【0021】
コンロ部3は赤外線を透過する耐熱ガラス2の下部に備えたもので、外壁7は上部を開口し底面形状を2本の赤外線にて加熱するランプヒータ4を中心に放物線形状とするとともに赤外線に対して反射率の高いアルミ材料とし内部壁面にケイ酸ナトリウム18をコーテイングしている。
【0022】
さらに、コンロ部3は耐熱ガラス2の直下にてスプリングバネA6により当接するとと
もに中央部の底面を局所的に上げ底部19にし、この上げ底部19に開口部20を備えている。温度センサ5は上げ底部19の開口部20に臨ませるとともにスプリングバネB21にて耐熱ガラス2に当接するように附勢されている。
【0023】
また、上面ケース13の一部に設けた操作部22には加熱開始キー23と加熱停止キー24、パワー切り替えキー25と表示ランプ26を基本に加熱選択キーとして揚げ物キー27、焼き肉キー28、鍋物キ29、および保温キー30を備えたものである。31はマイコンである。
【0024】
また、前記コンロ部3の上げ底部19のランプヒータ4側に熱抑制体32を備えている。
【0025】
なお、この種の加熱調理器に用いる耐熱ガラス2の板厚は4mm程度とし、鍋などを落としても割れにくいことと、高温の時に水ずがかかっても割れないように熱処理しセラミック化したものである。
【0026】
上記図1から図5の構成において動作を説明する。加熱調理器は加熱開始キー23を押し通電を開始すると、コンロ部3内部の複数本のランプヒータ4が発熱し直上部の耐熱ガラス2を透過し鍋などの被加熱物1を伝導とふく射により加熱される。順次説明する。
【0027】
(1)揚げ物キー27においては熱抑制体32にてランプヒータ4よりの熱を温度センサ5に適切に付加し被加熱物1の天ぷら、揚げ物油の温度上昇勾配と温度センサ5の温度上昇勾配を近似(応答時間の遅れを少なくしたもの)している。これにより、油加熱において適正温度(例えば、180〜200℃)にて満足な天ぷら、揚げ物加熱ができ且つ何らかの条件により異常過熱した場合に予めマイコンに入力している温度(例えば、260℃)に温度センサ5の温度が到達すると加熱手段としてのランプヒータ4を自動停止し油の発火を防止することを基本機能として実現したものである。
【0028】
(2)焼き物キー加熱のときは例えば焼き肉プレート加熱においては負荷が少ないときには温度センサ5が260℃にてランプヒータ4を自動停止すると使い勝手が悪くなる。また、焼き肉プレートの温度がオーバーシュートによりこれ以上となり、フッ素コーティングが過熱気味となり変色など不具合が発生するために温度設定としては240℃前後とし、制御としてはこの温度以上になるとランプヒータ4のパワーを自動的にダウンさせ、240℃前後未満になると自動的にフルパワーに戻すようにしたものである。また、フライパン加熱においても水分を発生する炒め物加熱の場合は良いが、水分の発生しない加熱(例えば、ウインナー、ごまめ)も同様なことが言える。
【0029】
(3)鍋キー加熱のときは土鍋の場合に少しでも加熱性能を良くするためにパワーをUPするか耐熱ガラス2の温度を少しでも高くするかである。しかし、これは鍋加熱中に温度センサ5が260℃に到達してしまいランプヒータ4を自動停止するために満足な土鍋加熱ができないものであった。そこで、温度センサ5の設定温度を上げるために、汎用性が高く低コストのサーミスタ(例えば、350℃以下のもの)とし予めマイコン31に入力しておいた温度を330℃前後としこの温度以上になるとランプヒータ4のパワーを自動的にダウンさせ、330℃前後未満になると自動的にフルパワーに戻すようにしたものである。
【0030】
(4)保温については食器の保温加熱(例えば、コーヒーサーバ、急須、酒とっくり、セラミック容器)と調理保温加熱(例えば、シチュー、カレー、肉じゃがなど)を実現したもので、保温キー加熱において(イ)コーヒーサーバ、急須などの保温では予め制御部に入力しておいた温度を80℃前後としこの設定温度以上にて加熱手段のパワーをOFF
し設定温度未満にて自動的にパワーONする制御としている。(ロ)シチュー、肉じゃがなどのような加熱を完了した後にそのまま保温する場合には温度センサ5は高温状態にあり、予め制御部に入力しておいた温度は80℃前後以上であり加熱手段のパワーはOFFのままである。その後、温度が低下してきて80℃前後未満となると自動的にパワーONする制御である。
【0031】
以上のように、本実施例1によれば、(1)ひとつの温度センサにて揚げ物、焼き肉、鍋物、および保温の四つの機能を適正に加熱制御するものである。(2)ひとつの温度センサであり簡単な構成にて加熱制御ができる。(3)フッ素コーティングの処理をした焼き肉プレートの適正加熱ができるとともに、土鍋加熱の場合に少しでも加熱性能を良くすることができるために使い勝手がよい。(4)揚げ物加熱時に油の発火を防止することができるために安全である。(5)何時までも温かく食べたい場合の食器保温(例えば、茶碗蒸し、グラタンなど)またはコーヒーサーバ、急須、などの加熱に大変便利となる。
【0032】
(実施例2)
図6は本発明の実施例2の加熱調理器の食器保温例の外観図である。
【0033】
本発明のものは加熱調理器に保温機能を付加したもので、保温加熱時はパワーは60W〜80Wとし耐熱ガラス2の温度設定として110℃〜130℃になるようにパワーを制御したもの。図1から図6に基ずいて説明する。
【0034】
保温加熱時は予め制御部に入力しておいた温度を80℃前後としこの設定温度以上にて加熱手段のパワーをOFFし設定温度未満にて自動的にパワーONする制御としている。
【0035】
従来、加熱調理器に保温機能を付加したものとしては、電磁誘導加熱器またはシーズヒータを渦巻き式にした電熱コンロなどがある。前者は加熱原理より陶器類、耐熱ガラスなどの食器をそのまま加熱することができない。後者は加熱面がフラットでないために、滑り落ちる可能性があり食器保温などはあまりしないものであった。つまり、両方ともに食器保温に対しては適性を欠いていた。
【0036】
本発明は、これらの課題を解決するもので、(1)赤外線加熱式のハロゲンランプヒータであり陶器類、耐熱ガラスなどの食器をそのまま加熱および保温ができるものである。(2)耐熱ガラス2を用いたフラット式加熱トップであり食器などが滑り落ちることなく保温ができる。(3)コーヒーサーバ、急須などの保温では耐熱ガラス2の温度設定を110℃〜130℃にすることにより、万が一、保温後に耐熱ガラス2に触れても火傷しにくい温度としている。このために、保温キー30のパワーは60W〜80Wとし、安全にて食器保温ができるようにしている。これは、この種の加熱調理器に用いる耐熱ガラス2の板厚は4mm程度であり、赤外線に対して反射率の高いアルミ材料とし内部壁面にケイ酸ナトリウム18をコーテイングしたコンロ部3との組合せにおいて最適化したものである。(4)シチューなどを加熱した後に調理保温する場合は耐熱ガラス2が加熱直後であり高温である。従って、この高温の熱にて保温されるために保温パワーは必要がなく、耐熱ガラスの温度が低下すると保温のためのパワーが必要となる。このために、予め制御部31に入力しておいた温度を80℃前後としこの設定温度以上にて加熱手段のパワーをOFFし設定温度未満にて自動的にパワーONする制御としている。
【0037】
つまり、保温キー30の加熱において温度センサ5は二つの働きをしているもので(1)耐熱ガラス2のが異常に高温になると安全性を確保するためにパワーを加熱制御している。(2)保温キー30の場合は温度センサ5にて耐熱ガラス2の温度を略一定(110℃〜130℃)に加熱制御するための機能。
【0038】
以上のように、本実施例2によれば、(1)耐熱ガラス2の温度を略一定(110℃〜130℃)にしているために万が一、保温後に耐熱ガラス2に触れても火傷しにくい温度であり安全であり且つ保温ができるものである。(2)保温する内容の加熱負荷に応じて自動運転するために経済的であり過熱も少なく便利である。(3)調理保温(例えば、カレー、シチュー)において省エネ保温ができる。
【0039】
【発明の効果】
以上説明したように、本発明の加熱調理器によれば、次の効果が得られる。
【0040】
(1)ひとつの温度センサにて揚げ物、焼き肉、鍋物、および保温の四つの機能を適正に加熱制御するものであり、簡単な構成にて加熱制御ができるとともに、フッ素コーティングの処理をした焼き肉プレート、フライパンの適正加熱、土鍋の加熱性能がを良く使い勝手がよい。また、揚げ物加熱時に油の発火を防止することができるために安全であるとともに、何時までも温かく食べたい場合の食器保温(例えば、茶碗蒸し、グラタンなど)またはコーヒーサーバ、急須、などの加熱に大変便利となる。
【0041】
(2)耐熱ガラスの温度を110℃〜130℃にて保温するために万が一、保温後に耐熱ガラスに触れても火傷しにくい温度であり安全であるとともに、調理保温(例えば、カレー、シチュー)において省エネ保温ができる。
【0042】
(3)パワーが60W〜80Wにて耐熱ガラスの温度を略一定(110℃〜130℃)にしているために、安全と保温が両立したものである。

BACKGROUND OF THE INVENTION
In the present invention, the object to be heated is heated through the heat-resistant glass directly above by the lamp heater that emits infrared rays provided in the stove part, and the temperature of the object to be heated is controlled by the temperature sensor provided in the lower part of the heat-resistant glass. Therefore, the present invention relates to a heating cooker that appropriately controls four heating functions with a single temperature sensor.
[0002]
[Prior art]
Conventionally, as this type of cooking device, there is JP-A-4-236016. The configuration will be described with reference to FIG.
[0003]
Conventionally, the temperature of the object to be heated 1 is controlled by a temperature sensor 5 provided at the lower part of the heat-resistant glass 2. The stove 3 is made of a heat insulating material and heat from the lamp heater 4 is added to the temperature sensor 5 as a bias. Heating is controlled.
[0004]
That is, the stove part 3 is provided in the lower part of the heat-resistant glass 2 on which the article to be heated 1 is placed, and the stove part 3 has a built-in temperature sensor 5 in contact with the lamp heater 4 and the lower part of the heat-resistant glass 2. ing. The stove section 3 has a vertical section with an opening at the top and side and bottom surfaces, and is abutted by a spring spring 6 immediately below the heat-resistant glass 2, and the outer wall 7 is made of a metal material. A ring-shaped heat insulating material A 8 and a donut-shaped heat insulating material B 9 are provided along the inner surface of the outer wall 7, and a cylindrical portion 10 is provided at the center of the outer wall 7. Further, a ring-shaped heat insulating material C11 is provided on the inner side (lamp heater side) of the cylindrical portion 10 and a heat insulating material D12 is provided on the upper surface of the heat insulating material C11 so that a gap is eliminated between the heat resistant glass 2 and the heat insulating material C11. Is.
[0005]
When heating is started with the above configuration, the lamp heater 4 inside the stove unit 3 generates heat, passes through the heat-resistant glass 2 immediately above, and heats the object 1 to be heated by conduction and radiation. As a specific example, the fried food heating will be described. Although most of the radiant heat from the lamp heater 4 is shielded by the three kinds of heat insulating materials for the temperature sensor 5, a small amount of heat is added as a bias to the heated sensor. This is an approximation of the temperature rise gradient of the oil of the object 1 and the temperature rise gradient of the temperature sensor 5 (response time delay is reduced).
[0006]
In this way, the temperature sensor 5 controls the heating in order to prevent the oil from igniting when the fried food is heated. When the temperature sensor 5 reaches the temperature previously input to the control unit, the lamp heater of the stove unit 3 4 is automatically stopped to prevent oil ignition and ensure safety.
[0007]
[Problems to be solved by the invention]
However, although the heating control of the conventional heating cooker shown in FIG. 7 can perform heating control for preventing overheating during fried food with a single temperature sensor, it has multifunctional functions such as pottery other than fried food, pot food, and heat insulation. Heating control is not possible.
[0008]
This is because fried foods, grilled foods, hot pots, and heat control for heat control require setting of optimum temperature and optimum control for each. For example, the temperature setting and heating control for preventing the ignition of oil during fried foods are clear as described above, but it prevents overheating of the fluorine-coated grilled meat plate, frying pan, etc. Temperature setting and heating control for pots, especially in the case of clay pots, to increase the power to improve the heating performance or to raise the temperature of the heat-resistant glass 2 as much as possible and to prevent emptying There is a problem that it is necessary to set the heating control such as the setting and heating control, and the heat retention of the coffee server and the like after the heating of the stew and the like.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention heats an object to be heated through a heat-resistant glass directly above by a lamp heater that emits infrared rays provided in a stove section, and is heated by a temperature sensor provided at the bottom of the heat-resistant glass. It controls the heating of objects, and it controls the heating of four functions with a single temperature sensor.
[0010]
According to the above invention, the cooking device can be used for multi-functional heating such as fried foods, grilled foods, pots, and heat insulation, and can be used safely and optimally.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The present invention comprises a heat-resistant glass on which an object to be heated is placed and a stove part with a heating means built in the lower part of the heat-resistant glass, and a temperature at which the object to be heated comes into contact with the heat-resistant glass in the stove part. It is equipped with a sensor and controls the four functions with a single temperature sensor. It has a fried food key, pottery key, pot key, and heat retention key.
[0012]
In addition, the four functions of fried food, grilled meat, hot pot, and heat insulation can be appropriately controlled with a simple configuration, and it is easy to use.
[0013]
In addition, it controls four functions with one temperature sensor. When fried food key is heated, the temperature input in advance to the control unit is around 260 ° C, and the heating means is automatically stopped above this temperature. When the key is set, the temperature input in advance to the controller is set to around 230 ° C, the power of the heating means is automatically reduced above this temperature and automatically returned to full power below the set temperature. automatically stopping the heating means at the front and rear 330 ° C. the temperature that has been input to the pre-Me control unit and this temperature or higher when the heating, 80 ° C. before and after the temperature had been entered in advance in the control unit when the insulation key In the configuration, the power of the heating means is turned off when the temperature is higher than the set temperature and the power is automatically turned on when the temperature is lower than the set temperature.
[0014]
And since it can prevent the ignition of oil at the time of fried food heating, while being safe, the heating performance in the case of the appropriate heating of the grilled meat plate which processed the fluorine coating, and earthenware pot heating is good. In addition, it is very convenient because it can keep dishes warm and cooked.
[0015]
In addition, it is equipped with a stove part made of aluminum and a temperature sensor for controlling the heating of an object to be heated by contacting a heat-resistant glass having a thickness of about 4 mm. A configuration in which the power is considerably smaller than the full power (for example, 60 W to 80 W) so that the temperature is substantially constant.
[0016]
And since the temperature of the heat resistant glass 2 is made substantially constant (110 ° C. to 130 ° C.) at a power of 60 W to 80 W, it is a temperature at which the heat resistant glass 2 is hard to be burned even if it is touched after the heat insulation, and both safety and heat insulation are achieved. It is a thing. In addition, energy saving heat can be kept in cooking heat retention (eg, curry, stew).
[0017]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0018]
Example 1
FIG. 1 is an external view of a cooking device according to Embodiment 1 of the present invention. FIG. 2 is a sectional view of the cooking device. Moreover, FIG. 3 is an external view of the stove part of the cooking device. Moreover, FIG. 4 is a figure of the operation part of the heating cooker. FIG. 5 is a control block diagram of the cooking device.
[0019]
One temperature sensor 5 controls heating of four functions of fried food, grilled meat, hot pot, and heat insulation.
[0020]
1 to 5, the heat-resistant glass 2 on which the object to be heated 1 is placed and which transmits infrared rays is integrated with the upper case 13 and the adhesive 14, and the lower case 16 including the stove 3 and the cooling fan 15 is built in. Is fixed and coupled with a screw 17.
[0021]
The stove part 3 is provided at the lower part of the heat-resistant glass 2 that transmits infrared rays, and the outer wall 7 has a parabolic shape centering on a lamp heater 4 that opens at the upper part and heats the bottom surface shape with two infrared rays. On the other hand, an aluminum material having high reflectance is coated with sodium silicate 18 on the inner wall surface.
[0022]
Further, the stove part 3 is brought into contact with the spring spring A 6 immediately below the heat-resistant glass 2 and the bottom surface of the central part is locally raised to a bottom part 19, and an opening part 20 is provided in the raised bottom part 19. The temperature sensor 5 is biased so as to face the opening 20 of the raised bottom portion 19 and to come into contact with the heat-resistant glass 2 by a spring spring B21.
[0023]
An operation unit 22 provided in a part of the upper case 13 has a heating start key 23, a heating stop key 24, a power switching key 25, and an indicator lamp 26 as heating selection keys. Key 29 and a heat retention key 30 are provided. 31 is a microcomputer.
[0024]
Further, a heat suppression body 32 is provided on the lamp heater 4 side of the raised bottom portion 19 of the stove portion 3.
[0025]
The thickness of the heat-resistant glass 2 used in this type of cooking device is about 4 mm, and it is heat treated and ceramicized so that it will not break even if a pan is dropped, and it will not break even when it is wet. Is.
[0026]
The operation of the configuration shown in FIGS. 1 to 5 will be described. When the heating cooker starts energization by pressing the heating start key 23, the plurality of lamp heaters 4 inside the stove unit 3 generate heat, pass through the heat-resistant glass 2 immediately above, and heat and radiate the heated object 1 such as a pan. Heated. A description will be made sequentially.
[0027]
(1) In the deep-fried food key 27, heat from the lamp heater 4 is appropriately added to the temperature sensor 5 by the heat suppression body 32, and the temperature rising gradient of the tempura of the heated object 1, the frying oil, and the temperature rising gradient of the temperature sensor 5. Is approximated (with less delay in response time). This makes it possible to heat tempura and fried foods that are satisfactory at an appropriate temperature (for example, 180 to 200 ° C.) in oil heating, and to a temperature (for example, 260 ° C.) that is input in advance to the microcomputer when abnormal overheating occurs under some conditions. When the temperature of the temperature sensor 5 reaches, the lamp heater 4 as a heating means is automatically stopped to prevent oil ignition as a basic function.
[0028]
(2) When the grill key is heated, for example, when the load is small in the grilled meat plate heating, if the temperature sensor 5 automatically stops the lamp heater 4 at 260 ° C., the usability deteriorates. In addition, the temperature of the grilled meat plate becomes higher due to overshoot, and the fluorine coating becomes overheated and causes problems such as discoloration. Therefore, the temperature setting is around 240 ° C. When the temperature exceeds this temperature, the power of the lamp heater 4 is controlled. Is automatically lowered, and when it is less than about 240 ° C., it is automatically returned to full power. In addition, the frying pan heating is good in the case of heating the stir-fry food that generates moisture, but the same can be said for the heating that does not generate moisture (for example, wiener, sesame).
[0029]
(3) In the case of pot key heating, in the case of a clay pot, the power is increased in order to improve the heating performance as much as possible, or the temperature of the heat-resistant glass 2 is increased as much as possible. However, since the temperature sensor 5 reached 260 ° C. during the pot heating and the lamp heater 4 was automatically stopped, satisfactory pot heating was not possible. Therefore, in order to raise the set temperature of the temperature sensor 5, a versatile and low-cost thermistor (for example, one having a temperature of 350 ° C. or lower) is set to about 330 ° C. and the temperature previously input to the microcomputer 31 is set to be higher than this temperature. Then, the power of the lamp heater 4 is automatically reduced, and when it is less than about 330 ° C., it is automatically returned to full power.

(Example 2)
FIG. 6 is an external view of a tableware heat insulation example of the heating cooker according to the second embodiment of the present invention.
[0033]
The thing of this invention adds the heat retention function to the heating cooker, and controls the power so that the power is 60 W to 80 W and the temperature setting of the heat resistant glass 2 is 110 ° C. to 130 ° C. during the heat insulation heating. A description will be given based on FIGS. 1 to 6.
[0034]
At the time of heat insulation heating, the temperature inputted in advance to the control unit is set to around 80 ° C., and the power of the heating means is turned off when the temperature is higher than the set temperature, and the power is automatically turned on when the temperature is lower than the set temperature.
[0035]
2. Description of the Related Art Conventionally, a heating cooker with a heat retaining function includes an electric induction cooker in which an electromagnetic induction heater or a sheathed heater is a spiral type. The former cannot heat tableware such as ceramics and heat-resistant glass as it is because of the heating principle. In the latter case, since the heating surface is not flat, there is a possibility of slipping down, so that the tableware is not kept warm. That is, both lacked suitability for tableware warming.
[0036]
The present invention solves these problems. (1) It is an infrared heating halogen lamp heater, which can heat and keep a tableware such as ceramics and heat-resistant glass as it is. (2) A flat-type heating top using the heat-resistant glass 2 and can keep warm without causing the tableware to slide down. (3) The temperature of the heat-resistant glass 2 is set to 110 ° C. to 130 ° C. in the heat retention of the coffee server, the teapot, etc., so that even if the heat-resistant glass 2 is touched after the heat retention, it is set to a temperature that is not easily burned. For this reason, the power of the heat retention key 30 is set to 60 W to 80 W so that the tableware can be kept warm. This is a combination of the heat-resistant glass 2 used in this type of cooking device with a thickness of about 4 mm and an aluminum material having a high reflectivity for infrared rays and a stove part 3 coated with sodium silicate 18 on the inner wall surface. Optimized in. (4) When cooking and keeping warm after heating a stew etc., the heat-resistant glass 2 is high temperature immediately after heating. Therefore, since the heat is maintained by this high temperature heat, there is no need for heat retention power. When the temperature of the heat-resistant glass is lowered, power for heat insulation is required. For this reason, the temperature input in advance to the control unit 31 is set to around 80 ° C., and the power of the heating unit is turned off when the temperature is higher than the set temperature, and the power is automatically turned on when the temperature is lower than the set temperature.
[0037]
That is, the temperature sensor 5 has two functions in the heating of the heat retention key 30. (1) When the heat-resistant glass 2 becomes abnormally high in temperature, the power is heated and controlled to ensure safety. (2) A function for controlling the temperature of the heat-resistant glass 2 to be substantially constant (110 ° C. to 130 ° C.) by the temperature sensor 5 in the case of the heat retention key 30.
[0038]
As described above, according to the second embodiment, (1) the temperature of the heat-resistant glass 2 is set to be substantially constant (110 ° C. to 130 ° C.). It is temperature, safe and can keep warm. (2) Since the automatic operation is performed according to the heating load of the content to be kept warm, it is economical and convenient with little overheating. (3) Energy-saving heat insulation can be performed in cooking heat insulation (for example, curry and stew).
[0039]
【The invention's effect】
As described above, according to the heating cooker of the present invention, the following effects can be obtained.
[0040]
(1) The fried food, grilled meat, hot pot, and the heat retaining function are properly heated and controlled with a single temperature sensor. The grilled meat plate can be heated and controlled with a simple structure, and has a fluorine coating treatment. , The proper heating of the frying pan and the heating performance of the earthenware pan are easy to use. In addition, it is safe because it can prevent the oil from igniting when fried food is heated, and it is very hard to heat dishes such as tea fumigation, gratin, etc. or coffee servers, teapots, etc. It becomes convenient.
[0041]
(2) In order to keep the temperature of the heat-resistant glass at 110 ° C. to 130 ° C., it should be safe to be burned even if it touches the heat-resistant glass after the temperature is kept, and it is safe to cook (for example, curry or stew). Energy saving heat can be kept.
[0042]
(3) Since the temperature of the heat-resistant glass is substantially constant (110 ° C. to 130 ° C.) at a power of 60 W to 80 W, safety and heat retention are compatible.
