以上のように構成された誘導加熱調理機器について、図３を参照して、動作および作用について説明する。
The operation and action of the induction heating cooking appliance configured as described above will be described with reference to FIG.
図３は、本発明の実施の形態１にかかる誘導加熱調理器のフローチャートである。
FIG. 3 is a flowchart of the induction heating cooker according to the first embodiment of the present invention.
まず、図３において、ステップ１（Ｓ１）にて、操作部８にある加熱開始キーをオンするとステップ２（Ｓ２）にて、加熱が開始される。
First, in FIG. 3, when the heating start key in the operation unit 8 is turned on in step 1 (S1), heating is started in step 2 (S2).
ステップ３（Ｓ３）にて、制御部１１は、出力設定部１２で設定された出力が、第１出力設定範囲内の設定出力であった場合、ステップ４（Ｓ４）に移行する。
In step 3 (S3), when the output set by the output setting unit 12 is a set output within the first output setting range, the control unit 11 proceeds to step 4 (S4).
ステップ４（Ｓ４）にて、制御部１１に出力された、赤外線センサ１３によって検知された調理容器３の鍋底温度が、予め設定された鍋底温度に対応する第１出力電圧値Ｖ１以上であった場合、ステップ５（Ｓ５）にて、焦げ付き検知部１４は、焦げ付き情報を制御部１１に出力する。次いで、制御部１１は、ステップ６（Ｓ６）にて焦げ付き情報に基づき、加熱停止を行う。
In step 4 (S4), the pot bottom temperature of the cooking container 3 detected by the infrared sensor 13 output to the control unit 11 was equal to or higher than the first output voltage value V1 corresponding to the preset pot bottom temperature. In this case, the burnt detection unit 14 outputs burnt information to the control unit 11 in step 5 (S5). Next, the control unit 11 stops heating based on the burnt information in step 6 (S6).
一方、ステップ３（Ｓ３）にて、出力設定部１２が第１出力設定範囲より大きい第２出力設定範囲の設定出力であった場合、ステップ７（Ｓ７）に移行する。
On the other hand, in step 3 (S3), when the output setting unit 12 is a setting output of the second output setting range larger than the first output setting range, the process proceeds to step 7 (S7).
ステップ７（Ｓ７）にて、赤外線センサ１３によって検知されて制御部１１に出力された調理容器３の鍋底温度が、予め設定された鍋底温度に対応しかつ第１出力電圧値Ｖ１より大きい第２出力電圧値Ｖ２以上であった場合、ステップ８（Ｓ８）にて、焦げ付き検知部１４は、焦げ付き情報を制御部１１に出力する。
In step 7 (S7), the pan bottom temperature of the cooking vessel 3 detected by the infrared sensor 13 and output to the control unit 11 corresponds to the preset pan bottom temperature and is larger than the first output voltage value V1. If the output voltage value is equal to or greater than V2, the burn detection unit 14 outputs burn information to the control unit 11 in step 8 (S8).
制御部１１は、ステップ９（Ｓ９）にて焦げ付き情報に基づき、加熱停止を行う。
Control unit 11 stops heating based on the burnt information in step 9 (S9).
例えば、出力設定部１２の第１出力設定範囲が３７０Ｗ相当の出力設定以下で、第２出力設定範囲が３７０Ｗ相当より大きい出力設定で、第１出力電圧値Ｖ１が赤外線センサ１３によって検知された調理容器３の鍋底温度が１３０℃に対応する出力電圧値で、第２出力電圧値Ｖ２が赤外線センサ１３によって検知された調理容器３の鍋底温度が１７０℃に対応する出力電圧値に、それぞれ設定したとする。そして、利用者が出力設定部１２で３７０Ｗ相当（第１出力設定範囲内）の出力を設定したとする。この場合には、焦げ付き情報を有効にし、その後調理容器３の鍋底温度が、１３０℃（第１出力電圧値Ｖ１）になると、ステップ５（Ｓ５）で焦げ付き情報を出力し、制御部１１は待機モードとなり加熱を停止して終了する。
For example, the first output setting range of the output setting unit 12 is equal to or less than the output setting equivalent to 370 W, the second output setting range is larger than the equivalent of 370 W, and the first output voltage value V1 is detected by the infrared sensor 13. The pot bottom temperature of the container 3 is an output voltage value corresponding to 130 ° C, and the second output voltage value V2 is set to an output voltage value corresponding to the pot bottom temperature of the cooking container 3 detected by the infrared sensor 13 corresponding to 170 ° C. And Then, it is assumed that the user sets an output corresponding to 370 W (within the first output setting range) by the output setting unit 12. In this case, when the burnt information is validated, and then the pan bottom temperature of the cooking container 3 reaches 130 ° C. (first output voltage value V1), burnt information is output in step 5 (S5), and the control unit 11 waits. It becomes mode and stops heating and ends.
一方、利用者が出力設定部１２で１０００Ｗ相当（第２出力設定範囲内）の出力を設定したとする。この場合には、焦げ付き情報を有効にし、その後調理容器３の鍋底温度が、１７０℃になると、焦げ付き情報を出力し、制御部１１は待機モードとなり加熱を停止して終了する。
On the other hand, it is assumed that the user sets an output equivalent to 1000 W (within the second output setting range) by the output setting unit 12. In this case, the burn-in information is validated, and after that, when the pan bottom temperature of the cooking container 3 reaches 170 ° C., the burn-in information is output, the control unit 11 enters the standby mode, stops heating, and ends.
以上のように、本実施の形態においては、赤外線センサを用いて焦げ付き検知動作を行い、かつ出力設定部１２にて設定された出力設定範囲に対応した焦げ付き検知を行うことにより、加熱モードにおいても、誤検知が起きる機会を減らしつつ焦げ付き検知機能を感度良く働かせ、焦げ付きの状態が悪化するのを防止すると共に不必要に加熱を停止することを防止し違和感なく調理を継続することができる。
As described above, in the present embodiment, by performing a burn detection operation using an infrared sensor and performing a burn detection corresponding to the output setting range set by the output setting unit 12, even in the heating mode. In addition, it is possible to continue the cooking without a sense of incongruity by reducing the chance of erroneous detection and making the burnt detection function work with high sensitivity, preventing the burnt state from deteriorating and preventing the heating from being stopped unnecessarily.
また、本実施の形態の制御部１１と焦げ付き検知部１４はマイクロコンピュータで構成することにより、簡単な構成にすることができる。
Also, the control unit 11 and the burnt detection unit 14 of the present embodiment can be configured simply by configuring them with a microcomputer.

図４は、本発明の実施の形態２にかかる誘導加熱調理機器のフローチャートである。 (Embodiment 2)
FIG. 4 is a flowchart of the induction heating cooking appliance according to the second embodiment of the present invention.
図４のフローチャートは、図３のフローチャートに比較して、ステップ２０（Ｓ２０）およびステップ２１（Ｓ２１）をさらに備えたことを特徴としている。ここで、実施の形態１と同様の部分については説明を省略し、異なる部分について説明する。
4 is characterized by further comprising step 20 (S20) and step 21 (S21) as compared to the flowchart of FIG. Here, description of the same parts as those in the first embodiment will be omitted, and different parts will be described.
まず、図４において、ステップ２０（Ｓ２０）にて、出力設定部１２が第２出力設定範囲より大きい第３出力設定範囲の設定出力であった場合、ステップ２１（Ｓ２１）に移行する。ステップ２１（Ｓ２１）にて、焦げ付き検知部１４からの焦げ付き情報に基づかず、出力制御を行う。すなわち、焦げ付き検知動作を禁止して行わない。そして、終了する（すなわち、加熱動作を継続する）。
First, in FIG. 4, when the output setting unit 12 is a setting output of the third output setting range larger than the second output setting range in step 20 (S20), the process proceeds to step 21 (S21). In step 21 (S21), output control is performed without being based on the burn information from the burn detection unit 14. That is, the burn detection operation is prohibited and not performed. And it complete | finishes (namely, heating operation is continued).
例えば、出力設定部１２の第２出力設定範囲が３７０Ｗ相当の出力設定より大きくかつ２０００Ｗ相当の出力設定未満で、第３出力設定範囲が２０００Ｗ相当以上の出力設定とする。そして、利用者が、出力設定部１２で、２０００Ｗ相当（第３出力設定範囲内）の出力を設定したとする。この場合には、制御部１１は、炒め物や湯沸しなどの高出力調理を始めたと判定し、焦げ付き情報を無効にし、すなわち、焦げ付き情報に基づかず、加熱調理を継続する。
For example, the second output setting range of the output setting unit 12 is larger than the output setting equivalent to 370 W and less than the output setting equivalent to 2000 W, and the third output setting range is set to the output setting equivalent to 2000 W or more. Then, it is assumed that the user sets an output equivalent to 2000 W (within the third output setting range) by the output setting unit 12. In this case, the control unit 11 determines that high-power cooking such as stir-fried food or kettle has started, invalidates the burnt information, that is, continues cooking without heating based on the burnt information.
一方、利用者が、出力設定部６で、２０００Ｗ相当の出力未満を設定したとする。制御部１１は、利用者が、一般に焦げ付きが懸念される調理を始めたと判定し、焦げ付き情報と出力情報に基づき、調理を継続する。
On the other hand, it is assumed that the user has set an output less than 2000 W in the output setting unit 6. The control unit 11 determines that the user has started cooking that is generally concerned about burning, and continues cooking based on the burning information and the output information.
以上のように、本実施の形態においては、出力設定部６にて設定された出力により、低出力調理時に焦げ付き情報を有効にし、かつ、高出力調理時に、無効にすることにより、焦げ付き検知の誤検知を避けることができ、利用者が、調理モードを選択しなくても違和感なく調理を継続することができる。
As described above, in the present embodiment, by setting the output setting unit 6 to enable scoring information during low output cooking and disabling during high output cooking, False detection can be avoided and cooking can be continued without a sense of incongruity even if the user does not select the cooking mode.
以上のように、本発明にかかる誘導加熱調理機器は、利用者が選択した出力設定範囲によって、焦げ付き検知が利用者にとって必要か不必要かを判別することにより、焦げ付き検知が不必要に働く機会を低減し、調理物の焦げ付きの状態が悪化するのを防止しつつ調理を行うことが可能となるので、組み込み式誘導加熱調理機器、卓上で使用される誘導加熱調理機器、据え置き式の誘導加熱調理機器などの使用形態、あるいは業務用、家庭用などの使用目的にかかわらずあらゆる種類の誘導加熱調理器全般の用途に有効である。
As described above, the induction cooking device according to the present invention has an opportunity to perform the burning detection unnecessarily by determining whether the burning detection is necessary or unnecessary for the user according to the output setting range selected by the user. Can be cooked while reducing the deterioration of the burnt state of the cooked product, so built-in induction heating cooking equipment, induction heating cooking equipment used on a table, stationary induction heating It is effective for all types of induction heating cookers in general, regardless of the type of use such as cooking equipment or the purpose of use such as business use and home use.
