Description

本発明は、外部の換気装置を連動運転させるビルトインコンロ等の加熱調理器に関する。   The present invention relates to a cooking device such as a built-in stove that operates an external ventilation device in conjunction.

ビルトインコンロ等の加熱調理器においては、器体に無線信号を送信可能な信号発信器を設ける一方、その上方に設置された外部の換気装置に信号受信器を設けて、加熱調理器の運転と運転停止とに連動して換気装置を自動運転させるようにしたものが知られている。特に特許文献１には、器体内で操作ボタンの上部に送信窓を設けてその内部に赤外線発光素子を前向きに設け、制御回路が操作ボタンの押し操作による調理開始又は調理終了を検出すると、制御回路が赤外線発光素子から赤外線信号を照射させることで、操作ボタンを操作する手に赤外線信号を反射させて上方の換気装置へ赤外線信号を送信するようにした発明が記載されている。   In a cooking device such as a built-in stove, a signal transmitter capable of transmitting a wireless signal is provided in the body, while a signal receiver is provided in an external ventilation device installed above the cooking device to operate the cooking device. A device that automatically operates the ventilator in conjunction with the shutdown is known. In particular, in Patent Document 1, a transmission window is provided at the top of an operation button in the body, an infrared light emitting element is provided in the inside thereof, and when the control circuit detects the start of cooking or the end of cooking by pressing the operation button, There is described an invention in which a circuit irradiates an infrared signal from an infrared light emitting element so that the infrared signal is reflected to a hand operating an operation button and the infrared signal is transmitted to an upper ventilation device.

しかし、特許文献１に記載の発明は、換気装置を連動させる赤外線信号の照射のタイミングを、ユーザによる操作ボタンの押し操作としているので、例えばタイマー調理を行った際、タイムアップして調理が自動的に終了しても、ユーザがこれに気づかずにいると換気装置は運転したままとなって無駄な電力消費が生じてしまう。これは、調理中にバーナに立ち消えが生じたり、回路異常が生じたりして安全機能が作動して安全弁が閉弁し、調理が自動的に終了した場合でも起こり得る。   However, in the invention described in Patent Document 1, the timing of irradiating the infrared signal for interlocking the ventilation device is the operation of pressing the operation button by the user. For example, when timer cooking is performed, the time is up and cooking is automatically performed. However, if the user is not aware of this, the ventilator remains in operation and wasteful power consumption occurs. This may occur even when cooking is automatically terminated when the burner disappears during cooking or a circuit abnormality occurs, the safety function is activated and the safety valve is closed.

一方、図５において、３１は、ビルトインコンロ１の上方に設置された換気装置で、回転する換気扇やその駆動部等を有するレンジフード３２を備えてなる。レンジフード３２の前面には、赤外線信号を受信するための赤外線受信センサ３３が設けられている。この赤外線受信センサ３３は、図示しない換気コントローラに電気的接続されており、ビルトインコンロ１の赤外線ＬＥＤ１９から発信される赤外線信号を赤外線受信センサ３３により受信すると、換気コントローラは、赤外線信号を読み取って換気扇をＯＮ／ＯＦＦ動作させるようになっている。   On the other hand, in FIG. 5, 31 is a ventilation device installed above the built-in stove 1 and includes a rotating hood, a range hood 32 having a driving unit thereof, and the like. An infrared receiving sensor 33 for receiving an infrared signal is provided on the front surface of the range hood 32. The infrared receiving sensor 33 is electrically connected to a ventilation controller (not shown). When the infrared receiving sensor 33 receives an infrared signal transmitted from the infrared LED 19 of the built-in stove 1, the ventilation controller reads the infrared signal and reads the ventilation fan. Is turned on / off.

以上の如く構成されたビルトインコンロ１及び換気装置３１の動作を、図６のフローチャートに基づいて説明する。
まず、Ｓ１で操作ボタン９〜１２の何れかが押し操作されると、Ｓ２で、そのガスバーナ２０のガス配管２１の安全弁２２と主弁２３とが開弁し、ガスバーナ２０へ燃料ガスが供給される。次に、Ｓ３で、マイクロスイッチ２９のＯＮ信号を得たコントローラ３０がイグナイタ２５を作動させて点火電極２６を連続放電させ、ガスバーナ２０に点火すると共に、安全弁２２への通電を開始する。これと同時に赤外線ＬＥＤ１９から所定の間隔で複数回、換気装置３１を運転させる赤外線信号（ＯＮ信号）を発信させる。このとき、赤外線信号は突出部１８から下向きに発信されるため、一部が床面に反射して図５の二点鎖線に示すような経路をたどって赤外線受信センサ３３へ到達し、換気装置３１を運転させる。 The operation of the built-in stove 1 and the ventilation device 31 configured as described above will be described based on the flowchart of FIG.
First, when any one of the operation buttons 9 to 12 is pushed in S1, the safety valve 22 and the main valve 23 of the gas pipe 21 of the gas burner 20 are opened in S2, and the fuel gas is supplied to the gas burner 20. The Next, in S3, the controller 30 having obtained the ON signal of the micro switch 29 operates the igniter 25 to continuously discharge the ignition electrode 26, ignite the gas burner 20, and start energizing the safety valve 22. At the same time, an infrared signal (ON signal) for operating the ventilation device 31 is transmitted from the infrared LED 19 a plurality of times at a predetermined interval. At this time, since the infrared signal is transmitted downward from the projecting portion 18, a part of the infrared signal is reflected on the floor surface and reaches the infrared receiving sensor 33 along the path shown by a two-dot chain line in FIG. 31 is operated.

Ｓ４の判別で、ガスバーナ２０の燃焼炎によって得られる熱電対２７の起電力が所定値以上に達すると、コントローラ３０は、Ｓ５で、安全弁２２への通電を継続して開弁状態を保持させる。なお、Ｓ４の判別で起電力が所定値に達しなければ、点火エラーが生じたとしてＳ６で安全弁２２への通電を停止して閉弁させる。次に、Ｓ７の判別で、他のガスバーナ２０が燃焼中か否か、すなわち、他のコンロ部４〜６又はグリル８において安全弁２２が開弁保持されているか否かが確認される。ここで燃焼中であれば、Ｓ９へ移行して他のコンロ部４〜６又はグリル８の監視を行うが、他に燃焼中のガスバーナ２０がなければ、Ｓ８で、赤外線ＬＥＤ１９から所定の間隔で複数回、換気装置３１の運転を停止させる赤外線信号（ＯＦＦ信号）を発信させて換気装置３１の運転を停止させる。このときも点火時と同様に赤外線信号は一部が床面に反射して赤外線受信センサ３３へ到達し、換気装置３１の運転を停止させることになる。
このように、ここでは点火エラーが生じた際にも換気装置３１が運転することで、燃焼せずに放出されたガスが滞留することなく換気される。 If the electromotive force of the thermocouple 27 obtained by the combustion flame of the gas burner 20 reaches a predetermined value or more in S4, the controller 30 continues to energize the safety valve 22 and keeps the valve open state in S5. If the electromotive force does not reach the predetermined value in the determination of S4, it is determined that an ignition error has occurred, and the power supply to the safety valve 22 is stopped and closed in S6. Next, in S7, it is confirmed whether or not the other gas burner 20 is in combustion, that is, whether or not the safety valve 22 is held open in the other stove parts 4 to 6 or the grill 8. If combustion is in progress, the process proceeds to S9 to monitor the other stove parts 4 to 6 or the grill 8, but if there is no other gas burner 20 that is still burning, in S8, the infrared LED 19 is spaced at a predetermined interval. An infrared signal (OFF signal) for stopping the operation of the ventilator 31 is transmitted a plurality of times to stop the operation of the ventilator 31. At this time, as in the ignition, a part of the infrared signal is reflected on the floor surface and reaches the infrared receiving sensor 33, and the operation of the ventilation device 31 is stopped.
As described above, when the ignition error occurs, the ventilation device 31 is operated to ventilate the gas released without burning without staying.

一方、ガスバーナ２０の燃焼中、コントローラ３０は、燃焼中のコンロ部４〜６又はグリル８において前述した各機能を実行する所定の条件の検出に伴って安全弁２２への通電を停止して閉弁させることでガスバーナ２０を自動消火させる。この所定の条件は、立ち消え安全機能では熱電対２７の起電力の所定値からの低下、過熱防止機能ではサーミスタ２８の電気抵抗の設定値への到達、タイマー調理機能ではタイマーのタイムアップ、消し忘れ防止機能では予め設定された連続使用時間のタイムアップであり、さらには回路異常の検出も所定の条件に含まれている。   On the other hand, during combustion of the gas burner 20, the controller 30 stops energization of the safety valve 22 in accordance with detection of predetermined conditions for executing the above-described functions in the burning stove units 4 to 6 or the grill 8 and closes the valve. By doing so, the gas burner 20 is automatically extinguished. This predetermined condition is that the electromotive force of the thermocouple 27 is lowered from a predetermined value in the extinction safety function, the electric resistance set value of the thermistor 28 is reached in the overheat prevention function, the timer is timed up in the timer cooking function, and the timer is forgotten to be turned off. In the prevention function, the preset continuous use time is up, and detection of a circuit abnormality is also included in the predetermined condition.

よって、Ｓ９の判別で自動消火させる所定の条件が確認されると、コントローラ３０は、Ｓ１０で該当するガスバーナ２０の安全弁２２への通電を停止する。次に、Ｓ１１で、熱電対２７の起電力が所定値より低下したか否かを判別する。ここで起電力の低下を確認したら、Ｓ１２で、他のガスバーナ２０が燃焼中か否かを確認する。ここで燃焼中であれば、Ｓ９へ戻って監視を続けるが、他に燃焼中のガスバーナ２０がなければ、Ｓ１３で、赤外線ＬＥＤ１９から所定の間隔で複数回、換気装置３１の運転を停止させる赤外線信号（ＯＦＦ信号）を発信させて換気装置３１の運転を停止させる。   Therefore, when the predetermined condition for automatic fire extinguishing is confirmed in the determination of S9, the controller 30 stops energizing the safety valve 22 of the corresponding gas burner 20 in S10. Next, in S11, it is determined whether or not the electromotive force of the thermocouple 27 has decreased below a predetermined value. If it is confirmed here that the electromotive force has decreased, it is confirmed in S12 whether or not the other gas burner 20 is burning. If combustion is in progress, the process returns to S9 and monitoring is continued. However, if there is no other gas burner 20 that is burning, the infrared ray that stops the operation of the ventilator 31 a plurality of times at predetermined intervals from the infrared LED 19 in S13. A signal (OFF signal) is transmitted to stop the operation of the ventilator 31.

そして、Ｓ１４で、燃焼中のコンロ部４〜６又はグリル８に対応する操作ボタン９〜１２が押し操作されると、Ｓ１５で、そのガスバーナ２０での主弁２３が閉弁し、ガスバーナ２０への燃料ガスの供給が停止される。次に、マイクロスイッチ２９のＯＦＦ信号を得たコントローラ３０は、Ｓ１６で、安全弁２２への通電を停止して閉弁させて、Ｓ１７で、他のガスバーナ２０が燃焼中か否かを確認する。ここで燃焼中であれば、Ｓ９へ戻って監視を続けるが、他に燃焼中のガスバーナ２０がなければ、コントローラ３０は、Ｓ１８で、赤外線ＬＥＤ１９から所定の間隔で複数回、換気装置３１の運転を停止させる赤外線信号（ＯＦＦ信号）を発信させて換気装置３１の運転を停止させる。   When the operation buttons 9-12 corresponding to the burning stove parts 4-6 or the grill 8 are pushed in S14, the main valve 23 in the gas burner 20 is closed in S15, and the gas burner 20 is turned on. The fuel gas supply is stopped. Next, the controller 30 which has obtained the OFF signal of the micro switch 29 stops energization of the safety valve 22 and closes it in S16, and confirms whether or not another gas burner 20 is in combustion in S17. If combustion is in progress, the process returns to S9 and monitoring is continued. However, if there is no other gas burner 20 in combustion, the controller 30 operates the ventilation device 31 a plurality of times at predetermined intervals from the infrared LED 19 in S18. An infrared signal (OFF signal) is transmitted to stop the operation of the ventilation device 31.

このように、上記形態１のビルトインコンロ１によれば、コントローラ３０は、安全弁２２への通電の開始に伴って赤外線ＬＥＤ１９によって換気装置３１のＯＮ信号を送信させる一方、安全弁２２への通電の停止に伴って赤外線ＬＥＤ１９によって換気装置３１のＯＦＦ信号を送信させることで、操作ボタン９〜１２の押し操作でなく、安全弁２２への通電とその停止とに合わせて換気装置３１の連動を図っているので、タイマー調理や安全機能の実行等による自動的な調理終了によっても換気装置３１を連動して停止させることができる。よって、換気装置３１の消し忘れが防止できて使い勝手が良好となる上、電力の節約にも繋がる。   Thus, according to the built-in stove 1 of the first aspect, the controller 30 causes the infrared LED 19 to transmit the ON signal of the ventilator 31 with the start of energization of the safety valve 22, while the energization of the safety valve 22 is stopped. Accordingly, by transmitting an OFF signal of the ventilator 31 by the infrared LED 19, the ventilator 31 is interlocked not only with the pressing operation of the operation buttons 9 to 12 but with the energization to the safety valve 22 and the stop thereof. Therefore, the ventilation device 31 can be stopped in conjunction with automatic cooking completion by timer cooking or execution of a safety function. Therefore, forgetting to turn off the ventilator 31 can be prevented and the usability is improved, and the power is saved.

特にここでは、ガスバーナ２０の燃焼炎を検出する熱電対２７を備え、コントローラ３０は、熱電対２７の起電力を監視して、安全弁２２への通電の停止によって起電力が所定値より低下したら赤外線ＬＥＤ１９によって換気装置３１をＯＦＦする無線信号を送信させるようにしているので、ガスバーナ２０が確実に消火するまで換気装置３１を運転させることができる。   In particular, here, a thermocouple 27 for detecting the combustion flame of the gas burner 20 is provided, and the controller 30 monitors the electromotive force of the thermocouple 27, and when the electromotive force drops below a predetermined value due to the stop of energization of the safety valve 22, infrared rays are transmitted. Since the wireless signal for turning off the ventilator 31 is transmitted by the LED 19, the ventilator 31 can be operated until the gas burner 20 is surely extinguished.

［形態２］
次に、本発明の他の形態を説明する。但し、ビルトインコンロ１や換気装置３１の構成は形態１と同じで、コントローラ３０による作動制御のみが異なるため、重複する説明は省略して当該作動制御を図７のフローチャートに基づいて説明する。
まず、Ｓ２１で操作ボタン９〜１２の何れかが押し操作されると、Ｓ２２で、そのガスバーナ２０のガス配管２１の安全弁２２と主弁２３とが開弁し、ガスバーナ２０へ燃料ガスが供給される。次に、Ｓ２３で、マイクロスイッチ２９のＯＮ信号を得たコントローラ３０がイグナイタ２５を作動させて点火電極２６を連続放電させ、ガスバーナ２０に点火すると共に、安全弁２２への通電を開始する。 [Form 2]
Next, another embodiment of the present invention will be described. However, the configuration of the built-in stove 1 and the ventilation device 31 is the same as that of the first embodiment, and only the operation control by the controller 30 is different. Therefore, the redundant description will be omitted and the operation control will be described based on the flowchart of FIG.
First, when any of the operation buttons 9 to 12 is pushed in S21, the safety valve 22 and the main valve 23 of the gas pipe 21 of the gas burner 20 are opened in S22, and the fuel gas is supplied to the gas burner 20. The Next, in S23, the controller 30 having obtained the ON signal of the micro switch 29 operates the igniter 25 to continuously discharge the ignition electrode 26, ignite the gas burner 20, and start energizing the safety valve 22.

次に、Ｓ２４の判別で、ガスバーナ２０の燃焼炎によって得られる熱電対２７の起電力が所定値以上に達すると、コントローラ３０は、Ｓ２５で、安全弁２２への通電を継続して開弁状態を保持させる。これと同時にコントローラ３０は、赤外線ＬＥＤ１９から所定の間隔で複数回、換気装置３１を運転させる赤外線信号（ＯＮ信号）を発信させる。なお、Ｓ２４の判別で起電力が所定値に達しなければ、点火エラーが生じたとしてＳ２６で安全弁２２への通電を停止して閉弁させる。   Next, when the electromotive force of the thermocouple 27 obtained by the combustion flame of the gas burner 20 reaches a predetermined value or more in the determination of S24, the controller 30 continues to energize the safety valve 22 and keeps the valve open state in S25. Hold. At the same time, the controller 30 transmits an infrared signal (ON signal) for operating the ventilation device 31 a plurality of times at predetermined intervals from the infrared LED 19. If the electromotive force does not reach the predetermined value in the determination of S24, it is determined that an ignition error has occurred, and the power supply to the safety valve 22 is stopped and closed in S26.

一方、Ｓ２７の判別で自動消火させる所定の条件が確認されると、コントローラ３０は、Ｓ２８で該当するガスバーナ２０の安全弁２２への通電を停止する。次に、Ｓ２９で、熱電対２７の起電力が所定値より低下したか否かを判別する。ここで起電力の低下を確認したら、Ｓ３０で、他のガスバーナ２０が燃焼中か否かを確認する。ここで燃焼中であれば、Ｓ２７へ戻って監視を続けるが、他に燃焼中のガスバーナ２０がなければ、Ｓ３１で、赤外線ＬＥＤ１９から所定の間隔で複数回、換気装置３１の運転を停止させる赤外線信号（ＯＦＦ信号）を発信させて換気装置３１の運転を停止させる。   On the other hand, when the predetermined condition for automatic fire extinguishing is confirmed in the determination in S27, the controller 30 stops energization of the safety valve 22 of the corresponding gas burner 20 in S28. Next, in S29, it is determined whether or not the electromotive force of the thermocouple 27 has decreased below a predetermined value. If it is confirmed here that the electromotive force has decreased, it is confirmed in S30 whether or not the other gas burner 20 is burning. If combustion is in progress, the process returns to S27 and monitoring is continued. However, if there is no other gas burner 20 in combustion, in S31, an infrared ray that stops the operation of the ventilator 31 a plurality of times at predetermined intervals from the infrared LED 19 is used. A signal (OFF signal) is transmitted to stop the operation of the ventilator 31.

そして、Ｓ３２で、燃焼中のコンロ部４〜６又はグリル８に対応する操作ボタン９〜１２が押し操作されると、Ｓ３３で、そのガスバーナ２０での主弁２３が閉弁し、ガスバーナ２０への燃料ガスの供給が停止される。次に、マイクロスイッチ２９のＯＦＦ信号を得たコントローラ３０は、Ｓ３４で、安全弁２２への通電を停止して閉弁させ、Ｓ３５で、熱電対２７の起電力が所定値より低下したか否かを判別する。ここで起電力の低下を確認したら、コントローラ３０は、Ｓ３６で、他のガスバーナ２０が燃焼中か否かを確認する。ここで燃焼中であれば、Ｓ２７へ戻って監視を続けるが、他に燃焼中のガスバーナ２０がなければ、Ｓ３７で、赤外線ＬＥＤ１９から所定の間隔で複数回、換気装置３１の運転を停止させる赤外線信号（ＯＦＦ信号）を発信させて換気装置３１の運転を停止させる。   When the operation buttons 9-12 corresponding to the burning stove parts 4-6 or the grill 8 are pushed in S32, the main valve 23 in the gas burner 20 is closed in S33, and the gas burner 20 is turned on. The fuel gas supply is stopped. Next, the controller 30 that has obtained the OFF signal of the micro switch 29 stops energization of the safety valve 22 and closes it in S34, and whether or not the electromotive force of the thermocouple 27 has decreased below a predetermined value in S35. Is determined. If it confirms the fall of an electromotive force here, the controller 30 will confirm whether other gas burners 20 are burning in S36. If combustion is in progress, the process returns to S27 and monitoring is continued. However, if there is no other gas burner 20 in combustion, in S37, an infrared ray that stops the operation of the ventilator 31 a plurality of times at a predetermined interval from the infrared LED 19 is used. A signal (OFF signal) is transmitted to stop the operation of the ventilator 31.

このように、上記形態２のビルトインコンロ１によれば、操作ボタン９〜１２の押し操作でなく、熱電対２７の起電力の上昇及び低下に合わせて換気装置３１の連動を図っているので、タイマー調理や安全機能の実行等による自動的な調理終了によっても換気装置３１を連動して停止させることができる。よって、換気装置３１の消し忘れが防止できて使い勝手が良好となる上、電力の節約にも繋がる。特にここでは、熱電対２７の起電力の変動を換気装置３１の運転及び運転停止の契機としているので、実際の燃焼炎の有無に合わせて換気装置３１を確実に連動させることができる。   Thus, according to the built-in stove 1 of the above-described form 2, since the ventilator 31 is interlocked with the rise and fall of the electromotive force of the thermocouple 27, not the push operation of the operation buttons 9-12, The ventilator 31 can also be stopped in conjunction with automatic cooking end by timer cooking or safety function execution. Therefore, forgetting to turn off the ventilator 31 can be prevented and the usability is improved, and the power is saved. In particular, here, since the fluctuation of the electromotive force of the thermocouple 27 is triggered by the operation and stoppage of the ventilator 31, the ventilator 31 can be reliably linked according to the presence or absence of the actual combustion flame.

なお、上記形態１，２において、ビルトインコンロの構成は適宜変更可能で、コンロ部の数の増減やグリルの省略は可能である。赤外線ＬＥＤも、上向きに設けたり、器体の両側に加えて器体の後方にも設置したり等、数や位置は変更できる。但し、信号発信器としては赤外線ＬＥＤに限らず、電波やレーザー等の他の無線信号の発信器を採用することも可能である。
また、上記形態１，２では、コントローラは、安全弁への通電停止や起電力の低下検出と同時に換気装置の運転を停止させるＯＦＦ信号を発信させるようにしているが、これに限らず、安全弁への通電停止や起電力の低下検出から所定時間の経過を待ってから換気装置へのＯＦＦ信号を発信させる遅延機能を付与してもよい。このようにすれば燃焼ガスや煙等をより確実に換気することができる。
その他、本発明はビルトインコンロに限らず、テーブルコンロであっても差し支えないし、ガスバーナを備えたガスオーブン等の他の加熱調理器であっても適用可能である。 In the first and second embodiments, the configuration of the built-in stove can be changed as appropriate, and the number of stove parts can be increased or decreased and the grill can be omitted. The number and position of the infrared LED can be changed, for example, the infrared LED can be provided upward, or can be installed on the rear side of the vessel in addition to the sides of the vessel. However, the signal transmitter is not limited to the infrared LED, and other wireless signal transmitters such as radio waves and lasers may be employed.
In the first and second embodiments, the controller is configured to send an OFF signal for stopping the operation of the ventilator at the same time as stopping the energization of the safety valve or detecting a decrease in electromotive force. A delay function for transmitting an OFF signal to the ventilator after waiting for the elapse of a predetermined time from the detection of the energization stop or the detection of the decrease in electromotive force may be added. In this way, combustion gas, smoke, etc. can be ventilated more reliably.
In addition, the present invention is not limited to a built-in stove, and may be a table stove, or may be applied to other cooking devices such as a gas oven equipped with a gas burner.
