ところで、加熱手段がグリル庫内に配設されるグリル調理と異なり、コンロバーナのように使用者が燃焼炎を視認できる加熱手段を用いるコンロ調理では、自動調理の実行中、消火状態にある加熱手段が使用者の予期しないタイミングで再点火されると、使用者が驚きを感じやすい。また、小径の調理容器を用いた自動調理の実行中、調理のタイミングに応じて使用者が手動で消火状態にある加熱手段を再点火させる場合でも、調理容器から大きな炎溢れが生じると、使用者が戸惑いを感じやすい。 By the way, unlike grill cooking in which the heating means is arranged in the grill chamber, in stove cooking using a heating means such as a stove burner in which the user can visually recognize the combustion flame, the heating in the extinguished state is performed during the execution of automatic cooking. The user is likely to be startled when the means is reignited at a timing unexpected by the user. Also, during automatic cooking using a small-diameter cooking container, even if the user manually reignites the extinguished heating means according to the timing of cooking, if a large flame overflows from the cooking container, the use of the people tend to feel confused.

According to the above heating cooker, when the heating means is reignited after the burning heating means is extinguished during automatic cooking, the heating means is ignited with a lower thermal power than the initial ignition, so that the user can It is possible to reduce the surprise and confusion of
Further, if the heating means is reignited by supplying a small amount of gas in a state where the temperature of the heating means is lowered, there is a risk of causing poor ignition. However, according to the above heating cooker, when the extinguishing time from extinguishing the heating means to reigniting is less than or equal to the predetermined reference time during the execution of automatic cooking, the gas supply amount at the time of reignition is reignited.

制御部は、自動調理の実行中、加熱手段を再点火させるとき、加熱手段温度検出手段の検出温度が所定の第2基準温度以上である場合、再点火時のガス供給量を、自動調理が開始される初期点火時のガス供給量である初期点火対応ガス供給量より少ない再点火対応ガス供給量に設定する制御構成を有する加熱調理器である。 When reigniting the heating means during execution of automatic cooking, if the temperature detected by the heating means temperature detecting means is equal to or higher than a predetermined second reference temperature, the control unit adjusts the gas supply amount at the time of reignition so that automatic cooking can be performed. The heating cooker has a control configuration for setting a re-ignition compatible gas supply amount smaller than the initial ignition compatible gas supply amount which is the gas supply amount at the time of initial ignition to be started.

上記加熱調理器によれば、加熱手段の所定位置の温度を検出する加熱手段温度検出手段により再点火時の加熱手段の温度状態を直接、判断することができる。そして、上記加熱調理器によれば、加熱手段温度検出手段の検出温度が所定の第2基準温度以上であるときに、再点火時のガス供給量が再点火対応ガス供給量に設定されるから、着火不良の生じ難い温度状態の加熱手段に少量のガスを供給して再点火させることができる。 According to the above heating cooker, the temperature state of the heating means at the time of reignition can be directly determined by the heating means temperature detecting means for detecting the temperature at the predetermined position of the heating means. According to the heating cooker, when the temperature detected by the heating means temperature detecting means is equal to or higher than the predetermined second reference temperature, the gas supply amount at the time of reignition is set to the reignition corresponding gas supply amount. It is possible to reignite the heating means by supplying a small amount of gas to the heating means at a temperature at which ignition failure is unlikely to occur.

被加熱物を自動で調理する自動調理機能を有する加熱調理器であって、 A heating cooker having an automatic cooking function for automatically cooking an object to be heated,
上方に載置される被加熱物をガスの燃焼炎によって加熱する加熱手段と、 heating means for heating an object to be heated placed above with a gas combustion flame;
加熱手段へのガス供給量を調整するガス供給量調整手段と、 gas supply amount adjusting means for adjusting the gas supply amount to the heating means;

制御部は、自動調理の実行中、加熱手段を再点火させるとき、再点火時のガス供給量を、自動調理が開始される初期点火時のガス供給量である初期点火対応ガス供給量より少ない再点火対応ガス供給量に設定し、 When reigniting the heating means during execution of automatic cooking, the control unit sets the gas supply amount at the time of reignition to be less than the gas supply amount corresponding to initial ignition, which is the gas supply amount at the time of initial ignition at which automatic cooking is started. Set the re-ignition compatible gas supply amount,

自動調理の実行中、再点火対応ガス供給量で加熱手段が再点火されなかった場合、再度、少量のガスを加熱手段に供給しても着火不良が生じる可能性が高い。そのため、被加熱物の再加熱が遅れて、自動調理が円滑に進行しない虞がある。しかしながら、上記加熱調理器によれば、自動調理の実行中に再点火によって点火されなかった加熱手段を再々点火させるとき、再々点火時のガス供給量が再点火対応ガス供給量より多く、初期点火対応ガス供給量以下に設定されるから、加熱手段をより確実に点火させることができる。 During execution of automatic cooking, if the heating means is not reignited with the gas supply amount corresponding to reignition, there is a high possibility that ignition failure will occur even if a small amount of gas is supplied to the heating means again. Therefore, reheating of the object to be heated may be delayed, and automatic cooking may not proceed smoothly. However, according to the above heating cooker, when re-igniting the heating means that was not ignited by re-ignition during automatic cooking, the gas supply amount at the time of re-ignition is larger than the gas supply amount corresponding to re-ignition, and the initial ignition Since it is set to the corresponding gas supply amount or less, the heating means can be ignited more reliably.

好ましくは、上記加熱調理器において、 Preferably, in the heating cooker,
制御部は、自動調理の実行中、加熱手段を自動で再点火させる。 The controller automatically reignites the heating means during automatic cooking.

上記加熱調理器によれば、自動調理の実行中、自動で加熱手段が再点火される場合でも、加熱手段は初期点火時より小さい火力で点火されるから、再点火のタイミングを知らない使用者が被加熱物の内容物をかき混ぜるなどのために加熱調理器近傍で作業している場合でも、使用者が驚きを感じ難い。 According to the above heating cooker, even if the heating means is automatically reignited during automatic cooking, the heating means is ignited with a lower thermal power than the initial ignition, so the user does not know the timing of reignition. Even when the user is working near the heating cooker for stirring the contents of the object to be heated, the user is less likely to feel surprise.

以上のように、本発明によれば、自動調理の実行中、加熱手段が消火された後、再点火されるときの使用者の驚きや戸惑いを低減することができる。従って、本発明によれば、使用者が快適に使用できる加熱調理器を提供することができる。 As described above, according to the present invention, it is possible to reduce the user's surprise and confusion when the heating means is extinguished and then reignited during automatic cooking. Therefore, according to the present invention, it is possible to provide a heating cooker that can be used comfortably by the user.

It becomes ignitable. Also, the setting display section 47 displays the set heating time, heating temperature, and the like. Then, when a predetermined cooking mode for automatic cooking is selected by the setting input switch 46, automatic cooking in the selected cooking mode becomes executable.

上記のように所定の調理モードが設定され、コンロ点消火操作子44にて点火操作がなされると(ステップST1で、Yes)、イグナイタ28を作動させて点火プラグ24から火花放電が行われるとともに、バルブユニット26を作動させて電磁開閉弁が開かれ、さらに流量調整弁の開度が所定の初期点火開度に調整される。その結果、コンロバーナ21に初期点火時のガス供給量である初期点火対応ガス供給量(例えば、1700kcal/h程度)のガスが供給され、上記火花放電により点火される(ステップST2)。そして、熱電対25で燃焼炎が検出されると、イグナイタ28の作動が停止され、バルブユニット26の流量調整弁の開度が選択された調理モードの第1加熱制御シーケンスに従って調整される。これにより、コンロバーナ21の火力が所定の第1加熱制御によって制御される自動調理が開始される(ステップST3)。 When the predetermined cooking mode is set as described above and the ignition operation is performed by the stove point extinguishing operation element 44 (Yes in step ST1), the igniter 28 is operated and the spark plug 24 discharges sparks. , the valve unit 26 is operated to open the electromagnetic on-off valve, and the opening of the flow control valve is adjusted to a predetermined initial ignition opening. As a result, gas is supplied to the stove burner 21 at an initial ignition corresponding gas supply amount (for example, about 1700 kcal/h), which is the gas supply amount at the time of initial ignition, and is ignited by the spark discharge (step ST2). When the thermocouple 25 detects combustion flame, the igniter 28 is deactivated and the opening of the flow control valve of the valve unit 26 is adjusted according to the first heating control sequence of the selected cooking mode. Thereby, automatic cooking is started in which the heating power of the stove burner 21 is controlled by the predetermined first heating control (step ST3).

上記第1加熱制御において、コンロバーナ21が点火状態にある時間(点火時間)が所定の加熱時間に達した場合や、鍋底温度Tfが所定の上限温度に達した場合などのコンロバーナ21の消火条件が満たされた場合、バルブユニット26の電磁開閉弁が閉弁されてコンロバーナ21へのガスの供給が遮断され、コンロバーナ21が消火される(ステップST4)。また、コンロバーナ21が消火され、熱電対25で燃焼炎が検出されなくなると、コンロバーナ21の消火時間Seを計測するためのタイマをスタートさせる(ステップST5)。 In the first heating control, extinguishing of the stove burner 21 when the time (ignition time) during which the stove burner 21 is in the ignition state reaches a predetermined heating time, or when the pan bottom temperature Tf reaches a predetermined upper limit temperature. When the condition is satisfied, the electromagnetic on-off valve of the valve unit 26 is closed, the gas supply to the stove burner 21 is cut off, and the stove burner 21 is extinguished (step ST4). Further, when the stove burner 21 is extinguished and the flame is no longer detected by the thermocouple 25, a timer for measuring the extinguishing time Se of the stove burner 21 is started (step ST5).

上記消火時間Seが所定の待機時間Stに達すると(ステップST6で、Yes)、鍋検出センサ27にて「鍋なし」が検出されているか否か、すなわち五徳22上に調理容器が載置されていない鍋なしの状態であるか否かが判定される(ステップST7)。このとき、鍋なしの状態であれば(ステップST7で、Yes)、後述するステップST8以降の制御動作を実行しないで自動調理を終了させる。これにより、コンロバーナ21が裸火で燃焼することを防止でき、安全性を確保することができる。なお、鍋検出センサ27で鍋ありの状態が検出されるまで待機してもよいし、鍋なしの状態を音声出力部52から報知させ、使用者に鍋の載置を喚起してもよい。 When the fire-extinguishing time Se reaches the predetermined waiting time St (Yes in step ST6), it is determined whether or not the pot detection sensor 27 detects that there is no pot, that is, whether or not the cooking container is placed on the trivet 22. It is determined whether or not there is no pan (step ST7). At this time, if there is no pan (Yes in step ST7), the automatic cooking is terminated without executing the control operations after step ST8, which will be described later. As a result, the stove burner 21 can be prevented from burning with an open flame, and safety can be ensured. It is possible to wait until the pan detection sensor 27 detects the presence of the pan, or to notify the absence of the pan from the voice output unit 52 to urge the user to place the pan.

消火時間Seが待機時間Stに達したとき(ステップST6で、Yes)、五徳22上に調理容器が載置された鍋ありの状態であれば(ステップST7で、No)、鍋底温度Tfが所定の第1基準温度(例えば、65℃)T1以上であるか否かを判定する(ステップST8)。 When the fire-extinguishing time Se reaches the standby time St (Yes in step ST6), if there is a pot with the cooking container placed on the trivet 22 (No in step ST7), the pot bottom temperature Tf reaches a predetermined value. is equal to or higher than a first reference temperature (for example, 65° C.) T1 (step ST8).

このとき、鍋底温度Tfが第1基準温度T1以上であれば(ステップST8で、Yes)、さらに消火時間Seが所定の基準時間(例えば、300秒間)S1以下であるか否かが判定される(ステップST9)。 At this time, if the pan bottom temperature Tf is equal to or higher than the first reference temperature T1 (Yes in step ST8), it is further determined whether or not the extinguishing time Se is equal to or shorter than a predetermined reference time (for example, 300 seconds) S1. (Step ST9).

その結果、鍋底温度Tfが第1基準温度T1以上であり(ステップST8で、Yes)、且つ消火時間Seが基準時間S1以下である場合(ステップST9で、Yes)、コンロバーナ21が少量のガスで再点火可能な高温状態と判定され、イグナイタ28を作動させて点火プラグ24から火花放電が行われるとともに、バルブユニット26を作動させて電磁開閉弁が開弁され、さらにコンロバーナ21へのガス供給量が、初期点火対応ガス供給量より一定量少ない所定の再点火対応ガス供給量(例えば、1200kcal/h程度)となるように流量調整弁の開度が調整されて、再点火が行われる(ステップST10)。図示しないが、このとき、点火直前に音声出力部52からコンロバーナ21の点火が報知される。これにより、使用者に注意を喚起することができる。 As a result, when the pot bottom temperature Tf is equal to or higher than the first reference temperature T1 (Yes in step ST8) and the fire-extinguishing time Se is equal to or shorter than the reference time S1 (Yes in step ST9), the stove burner 21 is operated with a small amount of gas. , the igniter 28 is operated to discharge sparks from the spark plug 24, the valve unit 26 is operated to open the electromagnetic on-off valve, and the gas to the stove burner 21 The opening degree of the flow control valve is adjusted so that the supply amount is a predetermined reignition-compatible gas supply amount (for example, about 1200 kcal/h) that is a certain amount less than the initial ignition-compatible gas supply amount, and re-ignition is performed. (Step ST10). Although not shown, at this time, the ignition of the stove burner 21 is reported from the voice output unit 52 immediately before the ignition. This can alert the user.

上記再点火により、熱電対25で燃焼炎が検出されると(ステップST11で、Yes)、イグナイタ28の作動が停止され、バルブユニット26の流量調整弁の開度が選択された調理モードの第2加熱制御シーケンスに従って調整される。これにより、コンロバーナ21の火力が所定の第2加熱制御によって制御される自動調理が再開される(ステップST12)。その後、上記ステップST12の第2加熱制御において、コンロバーナ21が消火されれば、自動調理を終了させる。 When a combustion flame is detected by the thermocouple 25 due to the above reignition (Yes in step ST11), the operation of the igniter 28 is stopped, and the opening degree of the flow control valve of the valve unit 26 is selected as the first cooking mode. 2 adjusted according to the heating control sequence. As a result, automatic cooking is restarted in which the heating power of the stove burner 21 is controlled by the predetermined second heating control (step ST12). After that, in the second heating control of step ST12, if the stove burner 21 is extinguished, the automatic cooking is terminated.

一方、鍋底温度Tfが第1基準温度T1未満である場合(ステップST8で、No)、または鍋底温度Tfが第1基準温度T1以上であるが、消火時間Seが基準時間S1を超えている場合(ステップST8で、Yes、ステップST9で、No)、コンロバーナ21が少量のガスでは着火不良が生じる可能性がある低温状態と判定され、イグナイタ28を作動させて点火プラグ24から火花放電が行われるとともに、バルブユニット26を作動させて電磁開閉弁が開弁され、さらにコンロバーナ21へのガス供給量が、初期点火対応ガス供給量となるように流量調整弁の開度が調整されて、再点火が行われる(ステップST13)。このとき、上記と同様に、点火直前に音声出力部52からコンロバーナ21の点火が報知される。なお、鍋底温度Tfが第1基準温度T1未満であったり、消火時間Seが基準時間S1より長かったりした場合、コンロバーナ21が消火されてから一定時間が経過しており、使用者が加熱調理器1近傍から離されている可能性が高いから、コンロバーナ21を初期点火対応ガス供給量で再点火させても、使用者の不快感は生じ難い。 On the other hand, if the pot bottom temperature Tf is less than the first reference temperature T1 (No in step ST8), or if the pot bottom temperature Tf is equal to or higher than the first reference temperature T1 but the extinguishing time Se exceeds the reference time S1 (Yes in step ST8, No in step ST9), it is determined that the stove burner 21 is in a low temperature state where ignition failure may occur with a small amount of gas, and the igniter 28 is operated to discharge sparks from the spark plug 24. At the same time, the valve unit 26 is operated to open the electromagnetic on-off valve, and the opening of the flow control valve is adjusted so that the amount of gas supplied to the stove burner 21 becomes the amount of gas supplied for initial ignition, Re-ignition is performed (step ST13). At this time, just before the ignition, the voice output unit 52 notifies the stove burner 21 of the ignition in the same manner as described above. If the pan bottom temperature Tf is less than the first reference temperature T1 or the extinguishing time Se is longer than the reference time S1, a certain period of time has passed since the stove burner 21 was extinguished, and the user cannot cook with heat. Since there is a high possibility that it is separated from the vicinity of the vessel 1, even if the stove burner 21 is reignited with the gas supply amount corresponding to the initial ignition, the user is unlikely to feel uncomfortable.

上記再点火により、熱電対25で燃焼炎が検出されると(ステップST14で、Yes)、イグナイタ28の作動が停止され、バルブユニット26の流量調整弁の開度が選択された調理モードの第2加熱制御シーケンスに従って調整される。これにより、コンロバーナ21の火力が所定の第2加熱制御によって制御される自動調理が再開される(ステップST12)。 When a combustion flame is detected by the thermocouple 25 due to the above reignition (Yes in step ST14), the operation of the igniter 28 is stopped, and the opening degree of the flow control valve of the valve unit 26 is selected for the first cooking mode. 2 adjusted according to the heating control sequence. As a result, automatic cooking is restarted in which the heating power of the stove burner 21 is controlled by the predetermined second heating control (step ST12).

上記ステップST10またはステップST13の再点火を行ったにも関わらず、熱電対25で燃焼炎が検出されなかった場合(ステップST11またはST14で、No)、着火不良が生じたと判定され、イグナイタ28の作動を停止させるとともに、バルブユニット26の電磁開閉弁が閉弁される。そして、イグナイタ28を再度、作動させて点火プラグ24から火花放電が行われるとともに、バルブユニット26を作動させて電磁開閉弁が開弁され、さらにコンロバーナ21へのガス供給量が、初期点火対応ガス供給量となるように流量調整弁の開度が調整されて、再々点火が行われる(ステップST15)。このとき、上記と同様に、点火直前に音声出力部52からコンロバーナ21の点火が報知される。 If the thermocouple 25 does not detect a combustion flame (No in step ST11 or ST14) despite the reignition in step ST10 or step ST13, it is determined that an ignition failure has occurred, and the igniter 28 is turned off. The operation is stopped and the electromagnetic on-off valve of the valve unit 26 is closed. Then, the igniter 28 is actuated again to discharge sparks from the spark plug 24, the valve unit 26 is actuated to open the electromagnetic on-off valve, and the amount of gas supplied to the stove burner 21 is reduced to correspond to the initial ignition. The opening degree of the flow control valve is adjusted so as to obtain the gas supply amount, and re-ignition is performed (step ST15). At this time, just before the ignition, the voice output unit 52 notifies the stove burner 21 of the ignition in the same manner as described above.

上記再々点火により、熱電対25で燃焼炎が検出されると(ステップST16で、Yes)、イグナイタ28の作動が停止され、バルブユニット26の流量調整弁の開度が選択された調理モードの第2加熱制御シーケンスに従って調整される。これにより、コンロバーナ21の火力が所定の第2加熱制御によって制御される自動調理が再開される(ステップST12)。一方、再々点火を行ったにも関わらず、熱電対25で燃焼炎が検出されなかった場合(ステップST16で、No)、上記ステップST12の第2加熱制御を実行することなく自動調理を終了させる。これにより、着火不良が繰り返し生じる場合に、継続して点火が行われることを防止することができる。なお、再々点火は、複数回、実行されてもよい。 When a combustion flame is detected by the thermocouple 25 by the re-reignition (Yes in step ST16), the operation of the igniter 28 is stopped, and the opening degree of the flow control valve of the valve unit 26 is selected for the first cooking mode. 2 adjusted according to the heating control sequence. As a result, automatic cooking is restarted in which the heating power of the stove burner 21 is controlled by the predetermined second heating control (step ST12). On the other hand, if the thermocouple 25 does not detect the combustion flame despite the re-ignition (No in step ST16), the automatic cooking is terminated without executing the second heating control in step ST12. . As a result, it is possible to prevent the ignition from being continuously performed when the ignition failure occurs repeatedly. Note that the re-reignition may be performed a plurality of times.

なお、図示を省略したが、ステップST7にて鍋なしの状態であると判定されたり、ステップST16にてコンロバーナ21の点火が検出されなかったりすると、自動調理が途中で終了したことが音声出力部52から報知される。また、ステップST12の第2加熱制御にてコンロバーナ21が消火されると、自動調理の正常な終了が音声出力部52から報知される。 Although not shown, if it is determined in step ST7 that there is no pan or if the ignition of the stove burner 21 is not detected in step ST16, a voice output indicating that the automatic cooking has ended halfway is output. It is notified from the unit 52 . Further, when the stove burner 21 is extinguished in the second heating control of step ST12, the normal end of the automatic cooking is notified from the voice output unit 52.

以上のように、本実施の形態によれば、自動調理の実行中にコンロバーナ21が消火された後、コンロバーナ21を自動で再点火させるときでも、コンロバーナ21が初期点火時より小さい火力で点火されるから、被加熱物の内容物をかき混ぜるなどのために再点火のタイミングを知らない使用者が加熱調理器1近傍で作業している場合でも、使用者は驚きを感じ難い。これにより、自動調理の実行中に自動でコンロバーナ21が再点火されるときの使用者の不快感を抑えることができる。 As described above, according to the present embodiment, even when the stove burner 21 is automatically reignited after the stove burner 21 is extinguished during the execution of automatic cooking, the heating power of the stove burner 21 is lower than that of the initial ignition. Therefore, even if a user who does not know the timing of reignition is working near the heating cooker 1 in order to stir the contents of the object to be heated, the user is unlikely to be surprised. As a result, the discomfort of the user when the stove burner 21 is automatically reignited during automatic cooking can be suppressed.

また、本実施の形態によれば、コンロバーナ21を自動で消火させた後、少量のガス量で自動で再点火させる自動調理が実行されるから、再点火により被加熱物の加熱を再開させたときの被加熱物の過熱が防止され、再点火から短時間で適切な状態に被加熱物を加熱することができるだけでなく、ガス消費量の低減を図ることができる。 Further, according to the present embodiment, automatic cooking is performed by automatically extinguishing the stove burner 21 and then automatically reigniting it with a small amount of gas. Not only can the object to be heated be heated to an appropriate state in a short time after reignition, but the gas consumption can be reduced.

また、本実施の形態によれば、自動調理の実行中、コンロバーナ21が消火されてから再点火されるまでの消火時間Seが基準時間S1以下であるかどうか、及び鍋底温度Tfが第1基準温度T1以上であるかどうかを判定するから、再点火時のコンロバーナ21の温度状態を類推することができる。すなわち、上記のように消火時間Se及び鍋底温度Tfを利用することにより、コンロバーナ21が着火不良の生じ難い温度状態であるかどうかを判定して、コンロバーナ21に少量のガスを供給して再点火させることができる。また、鍋底温度Tfの温度を検出することにより、調理容器の入れ替えを検出することもできる。 Further, according to the present embodiment, during execution of automatic cooking, whether or not the extinguishing time Se from extinguishing the stove burner 21 to reigniting is equal to or less than the reference time S1, and whether or not the pot bottom temperature Tf is the first Since it is determined whether or not the temperature is equal to or higher than the reference temperature T1, the temperature state of the stove burner 21 at the time of reignition can be analogized. That is, by using the extinguishing time Se and the pan bottom temperature Tf as described above, it is determined whether or not the stove burner 21 is in a temperature state in which ignition failure is unlikely to occur, and a small amount of gas is supplied to the stove burner 21. can be re-ignited. Also, by detecting the pot bottom temperature Tf, it is possible to detect replacement of the cooking vessel.

しかも、本実施の形態によれば、鍋底温度Tfが第1基準温度T1以上であっても、コンロバーナ21が消火されてから再点火させるまでの消火時間Seが基準時間S1を超えている場合、初期点火時のガス供給量である初期点火対応ガス供給量で再点火されるから、より確実にコンロバーナ21の温度状態を類推することができる。すなわち、使用者が他で加熱した調理容器を自動調理が実行されるコンロバーナ21上に載置すると、コンロバーナ21の温度が上昇していないにも関わらず、鍋底温度Tfが第1基準温度T1以上になる可能性がある。このような場合でも、再点火時のガス供給量を再点火対応ガス供給量に設定すると、着火不良が生じる虞がある。しかしながら、本実施の形態によれば、鍋底温度Tfが第1基準温度T1以上で、且つコンロバーナ21が消火されてから再点火させるまでの消火時間Seが基準時間S1以下でなければコンロバーナ21を再点火対応ガス供給量で再点火させないから、より確実に着火不良の生じ難い温度状態のコンロバーナ21に少量のガスを供給して再点火させることができる。これにより、自動調理の実行中の着火不良を防止でき、円滑に自動調理を続行させることができる。 Moreover, according to the present embodiment, even if the pan bottom temperature Tf is equal to or higher than the first reference temperature T1, the extinguishing time Se from extinguishing the stove burner 21 to reigniting it exceeds the reference time S1. , the temperature state of the stove burner 21 can be more reliably analogized because the gas is reignited at the gas supply amount corresponding to the initial ignition, which is the gas supply amount at the time of initial ignition. That is, when the user places a cooking container heated by another device on the stove burner 21 for automatic cooking, the pan bottom temperature Tf rises to the first reference temperature even though the temperature of the stove burner 21 does not rise. It can be T1 or higher. Even in such a case, if the re-ignition gas supply amount is set to the re-ignition compatible gas supply amount, there is a risk of ignition failure. However, according to the present embodiment, if the pan bottom temperature Tf is equal to or higher than the first reference temperature T1 and the extinguishing time Se from extinguishing the stove burner 21 to reigniting is equal to or shorter than the reference time S1, the stove burner 21 is not reignited with the gas supply amount corresponding to reignition, it is possible to reliably supply a small amount of gas to the stove burner 21 in a temperature state in which ignition failure is unlikely to occur and reignite it. As a result, ignition failure during execution of automatic cooking can be prevented, and automatic cooking can be continued smoothly.

なお、本実施の形態では、消火時間Se及び鍋底温度Tfに基づき再点火時のコンロバーナ21が再点火対応ガス供給量で着火不良が生じ難い温度状態であるかどうかを判定しているが、コンロバーナ21の所定位置の温度を直接、検出できる温度センサ(加熱手段温度検出手段)を天板11やコンロバーナ21の取り付け部材に付設し、温度センサで検出される温度が所定の第2基準温度以上である場合に、再点火時のガス供給量を再点火対応ガス供給量に設定してもよい。これにより、より確実に自動調理を続行させることができる。また、上記の消火時間Se及び鍋底温度Tfの両判定を行う場合と同様に、他の加熱手段で加熱した被加熱物が載置された場合の鍋底温度Tfによる誤検知を防止することができ、円滑に自動調理を続行させることができる。 In the present embodiment, it is determined whether or not the stove burner 21 at the time of reignition is in a temperature state in which ignition failure is unlikely to occur with the gas supply amount corresponding to reignition based on the extinguishing time Se and the pan bottom temperature Tf. A temperature sensor (heating means temperature detection means) capable of directly detecting the temperature at a predetermined position of the stove burner 21 is attached to the top plate 11 or the mounting member of the stove burner 21, and the temperature detected by the temperature sensor is a predetermined second reference. If it is equal to or higher than the temperature, the reignition gas supply amount may be set to the reignition compatible gas supply amount. As a result, automatic cooking can be continued more reliably. In addition, as in the case of determining both the extinguishing time Se and the pan bottom temperature Tf, it is possible to prevent erroneous detection due to the pan bottom temperature Tf when an object heated by other heating means is placed. , the automatic cooking can be continued smoothly.

また、本実施の形態によれば、自動調理の実行中に再点火によって点火されなかったコンロバーナ21を再々点火させるとき、再々点火時のガス供給量が初期点火対応ガス供給量に設定されるから、より確実にコンロバーナ21を点火させることができる。これにより、円滑に自動調理を続行させることができる。なお、再々点火時のガス供給量は、着火不良を防止するために、再点火対応ガス供給量より多く、初期点火対応ガス供給量以下に設定することが好ましい。 Further, according to the present embodiment, when re-igniting the stove burner 21 that has not been ignited by re-ignition during the execution of automatic cooking, the gas supply amount at the time of re-re-ignition is set to the initial ignition corresponding gas supply amount. Therefore, the stove burner 21 can be ignited more reliably. Thereby, automatic cooking can be continued smoothly. In order to prevent ignition failure, the gas supply amount at the time of re-reignition is preferably set to be larger than the reignition corresponding gas supply amount and equal to or less than the initial ignition corresponding gas supply amount.

以上のように、本実施の形態の加熱調理器によれば、自動調理の実行中、燃焼状態にある加熱手段が消火された後、再点火されるときの使用者の不快感を低減することができる。従って、本実施の形態によれば、使用者が快適に使用でき、安全に自動調理が実行される加熱調理器を提供することができる。 As described above, according to the heating cooker of the present embodiment, it is possible to reduce the user's discomfort when the heating means in the burning state is extinguished and then reignited during automatic cooking. can be done. Therefore, according to the present embodiment, it is possible to provide a heating cooker that can be comfortably used by a user and that can safely perform automatic cooking.

(その他の実施の形態)
(1)上記実施の形態では、自動調理の実行中に加熱手段を自動で消火させた後、自動で加熱手段を再点火させる場合について説明された。しかしながら、本発明は、自動調理の実行中、加熱手段を自動で消火させた後、手動で加熱手段を再点火させる場合についても適用することができる。例えば、複数の加熱手段を使用して調理を実行する場合、使用者が他の調理の進行状態を見ながら、調理タイミングに応じて自動調理が実行されている加熱手段を点火させたい場合がある。このような自動調理において、小径の調理容器が使用されていると調理容器からの炎溢れが大きくなって、使用者が戸惑いを感じやすい。従って、自動調理の実行中、消火状態の加熱手段を手動で再点火させる場合でも、再点火時のガス供給量を、初期点火対応ガス供給量より少ない再点火対応ガス供給量に設定することにより、使用者の不快感を低減することができる。
(Other embodiments)
(1) In the above embodiment, a case has been described in which the heating means is automatically extinguished during execution of automatic cooking, and then the heating means is automatically reignited. However, the present invention can also be applied to a case where the heating means is automatically extinguished during automatic cooking and then the heating means is manually reignited. For example, when cooking is performed using a plurality of heating means, the user may want to ignite the heating means that is performing automatic cooking according to the cooking timing while watching the progress of other cooking. . In such automatic cooking, if a small-diameter cooking container is used, the flame overflow from the cooking container increases, and the user is likely to feel confused. Therefore, even if the extinguished heating means is manually reignited during automatic cooking, the gas supply amount for reignition can be set to a reignition compatible gas supply amount smaller than the initial ignition compatible gas supply amount. , the user's discomfort can be reduced.

(2)上記実施の形態では、再点火対応ガス供給量は、初期点火対応ガス供給量よりも一定量少ないガス量に設定されている。しかしながら、本発明において、再点火対応ガス供給量は初期点火対応ガス供給量より少なければ、任意のガス量に設定することができる。例えば、自動調理の実行中、加熱手段の消火直前のガス供給量が初期点火対応ガス供給量より少ない場合、再点火時のガス供給量は消火直前のガス量に設定されてもよい。これによれば、消火前と略同等の火力で加熱が再開されるから、例えば、余熱調理時に加熱手段を消火した後、再点火する場合、過度の火力で被加熱物を加熱することなく、より早期に被加熱物を余熱調理に適した温度で加熱することができる。 (2) In the above embodiment, the gas supply amount for re-ignition is set to a certain amount less than the gas supply amount for initial ignition. However, in the present invention, the gas supply amount corresponding to reignition can be set to any gas amount as long as it is smaller than the gas supply amount corresponding to initial ignition. For example, during execution of automatic cooking, if the amount of gas supplied just before extinguishing the heating means is less than the amount of gas supplied for initial ignition, the amount of gas supplied during re-ignition may be set to the amount of gas immediately before extinguishing. According to this, since heating is resumed with substantially the same thermal power as before extinguishing, for example, when reigniting after extinguishing the heating means during residual heat cooking, the object to be heated is not heated with excessive thermal power. The object to be heated can be heated to a temperature suitable for residual heat cooking more quickly.

(3)上記実施の形態では、自動調理の実行中、第1加熱制御シーケンス及び第2加熱制御シーケンスに従って加熱手段の火力が調整されている。しかしながら、本発明は、自動調理の開始初期に使用者が手動で火力調整を行った後、自動で加熱手段の火力が調整されてもよい。 (3) In the above embodiment, the heating power of the heating means is adjusted according to the first heating control sequence and the second heating control sequence during execution of automatic cooking. However, in the present invention, the heating power of the heating means may be automatically adjusted after the user manually adjusts the heating power at the beginning of automatic cooking.
