Description

本発明は、自動調理機能及び自動調理復帰機能を有する加熱調理器に関する。より詳細には、本発明は、自動調理の実行中にバーナの消火操作や主電源のオフ操作が行われて自動調理が中断した場合でも、自動調理への復帰が可能な加熱調理器に関する。 The present invention relates to a cooking cooker having an automatic cooking function and an automatic cooking return function. More specifically, the present invention relates to a cooking cooker capable of returning to automatic cooking even when the automatic cooking is interrupted due to a fire extinguishing operation of a burner or an operation of turning off the main power during the execution of automatic cooking.

従来、食材など被調理物の加熱方法（調理モード）や加熱時間、さらには加熱温度を設定する設定入力手段と、調理容器や加熱庫内の温度を検出する温度検出手段と、バーナの燃焼時間を計時する計時手段とを備え、温度検出手段の検出温度が所定温度に達した場合やバーナの燃焼時間が所定時間に達した場合に、バーナを自動で消火するように構成された自動調理機能を備える加熱調理器が提案されている。 Conventionally, a setting input means for setting a heating method (cooking mode), a heating time, and a heating temperature of an object to be cooked such as foodstuffs, a temperature detecting means for detecting the temperature in a cooking container or a heating chamber, and a burning time of a burner. An automatic cooking function configured to automatically extinguish the burner when the detection temperature of the temperature detecting means reaches a predetermined temperature or when the burning time of the burner reaches a predetermined time. A cooking device equipped with is proposed.

また、自動調理の設定入力手段の操作を誤った場合を考慮して、バーナが点火されてから所定時間内であれば、設定入力手段による加熱方法等の変更を受け付ける自動調理機能を備えた加熱調理器も提案されている。これらの加熱調理器によれば、調理中、使用者が被調理物の調理状態を頻繁に監視する必要がないから、自動調理機能を備えていない加熱調理器に比べて使い勝手に優れる。 In addition, in consideration of the case where the operation of the setting input means for automatic cooking is mistaken, heating equipped with an automatic cooking function that accepts changes in the heating method, etc. by the setting input means within a predetermined time after the burner is ignited. Cookers have also been proposed. According to these cooking cookers, it is not necessary for the user to frequently monitor the cooking state of the object to be cooked during cooking, so that it is easier to use than a cooking cooker that does not have an automatic cooking function.

特開２０１５−２１３５５４号公報Japanese Unexamined Patent Publication No. 2015-21354 特開２０１５−４９０３０号公報JP-A-2015-49030 特開２０１０−１２７４８８号公報JP-A-2010-127488 特開２００６−５１１１４号公報Japanese Unexamined Patent Publication No. 2006-51114

ところで、調理中に誤ってバーナの点消火スイッチや主電源スイッチが操作されると、バーナが消火されて調理が中断される。このような調理の中断が自動調理の実行中に生じた場合、手動で調理を再開させるには、中断時点における被調理物の調理状態や既に経過した経過時間から必要とされる残りの加熱時間や再開後の火力を使用者が判断しなければならず、非常に困難である。このため、自動調理の実行中に誤って自動調理が中断された場合でも、短い中断時間であれば、バーナの再点火により自動調理へ復帰させることができる加熱調理器が望まれている。 By the way, if the burner's point fire extinguishing switch or main power switch is accidentally operated during cooking, the burner is extinguished and cooking is interrupted. If such a cooking interruption occurs during the execution of automatic cooking, the remaining heating time required from the cooking state of the object to be cooked at the time of the interruption and the elapsed time already elapsed in order to manually resume cooking. It is very difficult because the user has to judge the thermal power after restarting. Therefore, even if the automatic cooking is accidentally interrupted during the execution of the automatic cooking, a cooking cooker capable of returning to the automatic cooking by reigniting the burner is desired if the interruption time is short.

一方、燃焼安全装置としてバーナの炎孔近傍にバーナからの燃焼炎で加熱されて起電力を生じる熱電対を配置し、熱電対からの出力値に応じてバーナの点消火を判定する加熱調理器が知られている。自動調理の中断時にはバーナは消火されているから、自動調理の継続を望む場合、使用者はバーナを再点火させるために少なくとも点消火スイッチで点火操作を行う。そのため、点火操作を行うことにより自動調理が再開され、その点火処理において熱電対の起電力が着火検知レベル未満となる着火不良が生じると、バーナの未点火を認識した使用者は、再度、点消火スイッチの消火操作及び点火操作を試みる。 On the other hand, as a combustion safety device, a thermocouple that is heated by the combustion flame from the burner to generate an electromotive force is placed near the flame hole of the burner, and a heating cooker that determines the point fire extinguishing of the burner according to the output value from the thermocouple. It has been known. Since the burner is extinguished when the automatic cooking is interrupted, if the user wishes to continue the automatic cooking, the user performs an ignition operation with at least a point fire extinguishing switch to reignite the burner. Therefore, when automatic cooking is restarted by performing the ignition operation and an ignition failure occurs in which the electromotive force of the thermocouple becomes less than the ignition detection level in the ignition process, the user who recognizes the non-ignition of the burner again points. Attempt the fire extinguishing operation and ignition operation of the fire extinguishing switch.

しかしながら、自動調理機能を有する加熱調理器では、使用者が誤って自動調理を開始させたり、設定入力手段での加熱条件の設定を誤ったりした場合に自動調理を終了させるため、自動調理開始から一定時間は、自動調理が中断されても、自動調理への復帰を無効とする必要がある。また、既述したバーナの点火後、所定時間内であれば、設定入力手段による加熱条件の変更を受け付ける加熱調理器でも、変更を受け付けるためにその所定時間内は元の自動調理への復帰を無効とする必要がある。そのため、このような自動調理が開始されてから一定時間が経過するまでは自動調理への復帰が無効とされる加熱調理器の場合、上記したような自動調理の再開後、着火不良が生じて消火操作が行われると、自動調理へ復帰できないという問題がある。 However, in a cooking device having an automatic cooking function, if the user mistakenly starts automatic cooking or mistakenly sets the heating conditions in the setting input means, the automatic cooking is terminated. Therefore, from the start of automatic cooking. For a certain period of time, even if the automatic cooking is interrupted, it is necessary to invalidate the return to the automatic cooking. Further, even if the cooking cooker accepts the change of the heating condition by the setting input means within the predetermined time after the ignition of the burner described above, it returns to the original automatic cooking within the predetermined time in order to accept the change. Must be disabled. Therefore, in the case of a cooking cooker in which the return to automatic cooking is invalid until a certain period of time elapses after the start of such automatic cooking, ignition failure occurs after the restart of automatic cooking as described above. When the fire extinguishing operation is performed, there is a problem that it is not possible to return to automatic cooking.

本発明は上記課題を解決するものであり、本発明の目的は、自動調理機能及び自動調理復帰機能を有する加熱調理器において、使い勝手及び調理性能の向上を図ることにある。 The present invention solves the above problems, and an object of the present invention is to improve usability and cooking performance in a cooking cooker having an automatic cooking function and an automatic cooking return function.

With a burner that heats the food to be cooked
Point fire extinguishing means to operate the point fire extinguishing of the burner,
Thermocouples that generate electromotive force from the heat of the combustion flame from the burner,
Power operation means for turning on / off the main power of the appliance body,
A setting input means for setting and inputting heating conditions including the heating method and heating time of the object to be cooked,
A control means for automatic cooking operation that adjusts the heating power and heating time of the burner based on the heating conditions set by the setting input means,
A point fire extinguishing determination means for determining the point fire extinguishing of a burner based on the electromotive force output from the thermocouple,
An automatic cooking interruption operation determining means for determining whether or not an automatic cooking interruption operation of either a fire extinguishing operation of a burner or an operation of turning off the main power is performed during automatic cooking.
The interruption time from the automatic cooking interruption operation to the automatic cooking restoration operation of either the ignition operation of the burner corresponding to the automatic cooking interruption operation or the ignition operation of the burner after the main power is turned on is automatically cooked. A return time limit timing means for determining whether or not the operation is within a predetermined return time limit, and
It is provided with a return function invalidation means for disabling the automatic cooking return function until a predetermined invalid time elapses after the burner is ignited and the automatic cooking is started or restarted.
If the first automatic cooking interruption operation is performed during automatic cooking execution, the automatic cooking is interrupted.
If the first automatic cooking return operation after the automatic cooking is interrupted by the first automatic cooking interruption operation is performed after the invalid time has elapsed and within the return time limit, the automatic cooking is restarted.
When the first automatic cooking return operation is performed and the automatic cooking is restarted, the electromotive force of the thermocouple falls below the predetermined ignition detection level, and when the second automatic cooking interruption operation, the burner fire extinguishing operation, is performed, the automatic cooking is performed. Suspend,
After the second automatic cooking interruption operation, when the burner ignition operation, which is the second automatic cooking return operation, is performed, the second automatic cooking return operation is performed without timing the invalid time from the first automatic cooking return operation. A cooking cooker having a control configuration for restarting automatic cooking is provided within the recovery time limit after the automatic cooking interruption operation is performed.

上記加熱調理器によれば、自動調理中に意図せず点消火手段の消火操作または主電源のオフ操作の自動調理中断操作がなされて自動調理が中断されても、所定の無効時間経過後で、且つ所定の復帰制限時間内に自動調理復帰操作を行ってバーナを再点火させれば、引き続き自動調理を中断時の状態から再開させる自動調理復帰機能を備えているから、復帰後の残りの加熱時間やバーナの火力を使用者が判断する必要がない。また、上記加熱調理器では、バーナの点火操作がなされて自動調理の開始または再開がされてから所定の無効時間が経過するまでは自動調理中断操作が行われても自動調理への復帰を無効とするから、自動調理が誤設定された場合の調理初期の自動調理の中止や加熱条件の設定を変更する時間を確保できる。 According to the above-mentioned cooking cooker, even if the automatic cooking is interrupted due to an unintentional fire extinguishing operation of the point fire extinguishing means or an automatic cooking interruption operation of turning off the main power during automatic cooking, after a predetermined invalid time elapses. In addition, if the burner is reignited by performing the automatic cooking return operation within the predetermined return time limit, the automatic cooking return function that restarts the automatic cooking from the interrupted state is provided. It is not necessary for the user to judge the heating time and the heating power of the burner. Further, in the above-mentioned cooking cooker, the return to automatic cooking is invalid even if the automatic cooking interruption operation is performed until a predetermined invalid time elapses after the burner is ignited and the automatic cooking is started or restarted. Therefore, when automatic cooking is erroneously set, it is possible to secure time for stopping automatic cooking at the initial stage of cooking and changing the setting of heating conditions.

一方、上記加熱調理器では、自動調理の再開から無効時間が経過するまでは自動調理復帰機能が無効とされるから、第１自動調理中断操作後の第１自動調理復帰操作が、無効時間の経過後で、且つ復帰制限時間内になされて、自動調理が再開されると、第１自動調理復帰操作から無効時間が経過するまで自動調理への復帰が制限される。この第１自動調理復帰操作がなされて自動調理が再開されたときに熱電対の起電力が所定の着火検知レベル未満になる着火不良が生じると、第１自動調理復帰操作を行った使用者は加熱調理器近傍にいるから、通常、使用者は第２自動調理中断操作であるバーナの消火操作及び第２自動調理復帰操作であるバーナの点火操作を第１自動調理復帰操作から短時間内に行う。その結果、第２自動調理中断操作で中断された自動調理を復帰させる第２自動調理復帰操作が、第１自動調理復帰操作からの無効時間内に行われて、自動調理に復帰させることができないという問題がある。 On the other hand, in the above-mentioned cooking cooker, since the automatic cooking return function is disabled from the restart of automatic cooking until the invalid time elapses, the first automatic cooking return operation after the first automatic cooking interruption operation is the invalid time. After the lapse of time and within the return time limit, when the automatic cooking is restarted, the return to the automatic cooking is restricted until the invalid time elapses from the first automatic cooking return operation. When the first automatic cooking return operation is performed and the automatic cooking is restarted, when an ignition failure occurs in which the electromotive force of the thermocouple becomes less than the predetermined ignition detection level, the user who has performed the first automatic cooking return operation Since the user is in the vicinity of the cooking cooker, the user usually performs the second automatic cooking interruption operation, the burner fire extinguishing operation, and the second automatic cooking restoration operation, the burner ignition operation, within a short time from the first automatic cooking restoration operation. Do. As a result, the second automatic cooking return operation for returning the automatic cooking interrupted by the second automatic cooking interruption operation is performed within the invalid time from the first automatic cooking return operation, and the automatic cooking cannot be returned. There is a problem.

しかしながら、上記加熱調理器によれば、第２自動調理中断操作後、第２自動調理復帰操作であるバーナの点火操作がなされると、第１自動調理復帰操作からの無効時間を計時することなく、第２自動調理復帰操作が第２自動調理中断操作がなされてからの復帰制限時間内であれば、自動調理を再開させるから、第１自動調理復帰操作で着火不良が生じた場合でも、再度、自動調理へ復帰させることができる。 However, according to the above-mentioned cooking cooker, when the burner ignition operation, which is the second automatic cooking return operation, is performed after the second automatic cooking interruption operation, the invalid time from the first automatic cooking return operation is not timed. , If the second automatic cooking return operation is within the return time limit after the second automatic cooking interruption operation is performed, the automatic cooking is restarted. Therefore, even if an ignition failure occurs in the first automatic cooking return operation, it is restarted. , Can be returned to automatic cooking.

The interruption time from the automatic cooking interruption operation to the automatic cooking restoration operation of either the ignition operation of the burner corresponding to the automatic cooking interruption operation or the ignition operation of the burner after the main power is turned on is automatically cooked. A return time limit timing means for determining whether or not the operation is within a predetermined return time limit, and
It is provided with a return function invalidation means for disabling the automatic cooking return function until a predetermined invalid time elapses after the burner is ignited and the automatic cooking is started or restarted.
If the first automatic cooking interruption operation is performed during automatic cooking execution, the automatic cooking is interrupted.
If the first automatic cooking return operation after the automatic cooking is interrupted by the first automatic cooking interruption operation is performed after the invalid time has elapsed and within the return time limit, the automatic cooking is restarted.
When the first automatic cooking return operation is performed and the automatic cooking is restarted, the electromotive force of the thermocouple falls below the predetermined ignition detection level, and when the second automatic cooking interruption operation, the burner fire extinguishing operation, is performed, the automatic cooking is performed. Suspend,
When the burner ignition operation, which is the second automatic cooking return operation, is performed after the second automatic cooking interruption operation, the second automatic cooking return operation is performed even within the invalid time from the first automatic cooking return operation. The return time limit after the automatic cooking interruption operation is performed, or the return time limit after the first automatic cooking interruption operation is performed by the second automatic cooking return operation has passed, but the second automatic cooking is performed. A cooking cooker having a control configuration for restarting automatic cooking is provided within the return time limit after the interruption operation is performed.

上記加熱調理器によれば、自動調理中に意図せず点消火手段の消火操作または主電源のオフ操作の自動調理中断操作がなされて自動調理が中断されても、所定の無効時間経過後で、且つ所定の復帰制限時間内に自動調理復帰操作を行ってバーナを再点火させれば、引き続き自動調理を中断時の状態から再開させる自動調理復帰機能を備えているから、復帰後の残りの加熱時間やバーナの火力を使用者が判断する必要がない。また、上記加熱調理器では、バーナの点火操作がなされて自動調理の開始または再開がされてから所定の無効時間が経過するまでは自動調理中断操作が行われても自動調理への復帰を無効とするから、自動調理が誤設定された場合の調理初期の自動調理の中止や加熱条件の設定を変更する時間を確保できる。 According to the above-mentioned cooking cooker, even if the automatic cooking is interrupted due to an unintentional fire extinguishing operation of the point fire extinguishing means or an automatic cooking interruption operation of turning off the main power during automatic cooking, after a predetermined invalid time elapses. In addition, if the burner is reignited by performing the automatic cooking return operation within the predetermined return time limit, the automatic cooking return function that restarts the automatic cooking from the interrupted state is provided. It is not necessary for the user to judge the heating time and the heating power of the burner. Further, in the above-mentioned cooking cooker, the return to automatic cooking is invalid even if the automatic cooking interruption operation is performed until a predetermined invalid time elapses after the burner is ignited and the automatic cooking is started or restarted. Therefore, when automatic cooking is erroneously set, it is possible to secure time for stopping automatic cooking at the initial stage of cooking and changing the setting of heating conditions.

一方、上記加熱調理器では、自動調理の再開から無効時間が経過するまでは自動調理復帰機能が無効とされるから、第１自動調理中断操作後の第１自動調理復帰操作が、無効時間の経過後で、且つ復帰制限時間内になされて、自動調理を再開させると、第１自動調理復帰操作から無効時間が経過するまで自動調理への復帰が制限される。この第１自動調理復帰操作がなされて自動調理が再開されたときに熱電対の起電力が所定の着火検知レベル未満になって着火不良が生じると、第１自動調理復帰操作を行った使用者は加熱調理器近傍にいるから、通常、使用者は第２自動調理中断操作であるバーナの消火操作及び第２自動調理復帰操作であるバーナの点火操作を第１自動調理復帰操作から短時間内に行う。その結果、第２自動調理中断操作で中断された自動調理を復帰させる第２自動調理復帰操作が、第１自動調理復帰操作からの無効時間内に行われて、自動調理に復帰させることができないという問題がある。 On the other hand, in the above-mentioned cooking cooker, since the automatic cooking return function is disabled from the restart of automatic cooking until the invalid time elapses, the first automatic cooking return operation after the first automatic cooking interruption operation is the invalid time. If the automatic cooking is restarted after the lapse of time and within the return time limit, the return to the automatic cooking is restricted until the invalid time elapses from the first automatic cooking return operation. When the first automatic cooking return operation is performed and the automatic cooking is restarted, the electromotive force of the thermocouple becomes less than the predetermined ignition detection level and ignition failure occurs, the user who performed the first automatic cooking return operation. Is near the cooker, so the user usually performs the second automatic cooking interruption operation, the burner fire extinguishing operation, and the second automatic cooking return operation, the burner ignition operation, within a short time from the first automatic cooking return operation. To do. As a result, the second automatic cooking return operation for returning the automatic cooking interrupted by the second automatic cooking interruption operation is performed within the invalid time from the first automatic cooking return operation, and the automatic cooking cannot be returned. There is a problem.

しかしながら、上記加熱調理器によれば、第２自動調理中断操作後、第２自動調理復帰操作であるバーナの点火操作がなされると、第１自動調理復帰操作からの無効時間内であっても、第２自動調理復帰操作が第１自動調理中断操作がなされてからの復帰制限時間内であるか、または第２自動調理復帰操作が第１自動調理中断操作がなされてからの復帰制限時間を経過しているが、第２自動調理中断操作がなされてからの復帰制限時間内であれば、自動調理を再開させるから、第１自動調理復帰操作で着火不良が生じた場合でも、再度、自動調理へ復帰させることができる。 However, according to the above-mentioned cooking cooker, if the burner ignition operation, which is the second automatic cooking return operation, is performed after the second automatic cooking interruption operation, even within the invalid time from the first automatic cooking return operation. , The second automatic cooking return operation is within the return time limit after the first automatic cooking interruption operation is performed, or the second automatic cooking return operation is the return time limit after the first automatic cooking interruption operation is performed. Although it has passed, if it is within the recovery time limit after the second automatic cooking interruption operation is performed, the automatic cooking is restarted. Therefore, even if an ignition failure occurs in the first automatic cooking return operation, the automatic cooking is performed again. You can return to cooking.

好ましくは、上記他の一局面に係る加熱調理器において、
第２自動調理中断操作がなされてからの復帰制限時間は、第１自動調理中断操作がなされてからの復帰制限時間よりも短時間に設定される。 Preferably, in the cooking apparatus according to the other aspect,
The return time limit after the second automatic cooking interruption operation is performed is set to be shorter than the return time limit after the first automatic cooking interruption operation is performed.

第２自動調理復帰操作が第１自動調理中断操作がなされてからの復帰制限時間を経過しているが、第２自動調理中断操作がなされてからの復帰制限時間内であれば、自動調理を再開させる場合、自動調理中断操作がなされてからの復帰制限時間を固定すると、第１自動調理中断操作から被調理物が長時間、加熱されず、被調理物の温度が低下した状態から自動調理が再開され、食味が低下する可能性がある。
しかしながら、上記加熱調理器によれば、第２自動調理中断操作がなされてからの復帰制限時間は、第１自動調理中断操作がなされたときの復帰制限時間よりも短時間に設定されるため、調理物の温度の低下の少ない状態から自動調理を再開させることができる。 The return time limit for the second automatic cooking interruption operation has passed since the first automatic cooking interruption operation was performed, but if it is within the return time limit after the second automatic cooking interruption operation is performed, automatic cooking is performed. When restarting, if the return time limit after the automatic cooking interruption operation is fixed, the food to be cooked will not be heated for a long time from the first automatic cooking interruption operation, and automatic cooking will be performed from the state where the temperature of the food to be cooked has dropped. May be restarted and the taste may deteriorate.
However, according to the above-mentioned cooking cooker, the return time limit after the second automatic cooking interruption operation is performed is set to be shorter than the return time limit when the first automatic cooking interruption operation is performed. Automatic cooking can be restarted from a state where the temperature of the cooked food does not drop much.

以上のように、本発明によれば、自動調理中に意図せず点消火手段の消火操作や主電源のオフ操作の自動調理中断操作が行われても、調理を継続させる場合に、復帰後のバーナの火力や加熱時間を使用者が判断して設定する必要がない。また、自動調理の復帰時に熱電対によるバーナの着火不良が検知されても、自動調理を再開させることができる。従って、本発明によれば、自動調理機能及び自動調理復帰機能を有する加熱調理器において、使い勝手及び調理性能を向上させることができる。 As described above, according to the present invention, even if the fire extinguishing operation of the point fire extinguishing means or the automatic cooking interruption operation of the main power off operation is performed unintentionally during the automatic cooking, when the cooking is continued, after the return. It is not necessary for the user to judge and set the heating power and heating time of the burner.

次に、図４〜図６に示すフローチャートを参照して、コンロバーナ２１で自動調理実行中に自動調理中断操作がなされた場合の制御動作を説明する。なお、自動調理実行中に電源スイッチ４３で主電源のオフ操作により自動調理が中断されたときに自動調理へ復帰させる場合の制御動作は、コンロ点消火操作子４４の点火操作前に自動調理復帰操作として電源スイッチ４３のオン操作がなされたかどうかを判定する以外、コンロ点消火操作子４４の消火操作により自動調理が中断されたときのそれと同様である。このため、以下では、主として自動調理実行中にコンロ点消火操作子４４の消火操作により自動調理が中断された場合を例に挙げて説明する。 Next, the control operation when the automatic cooking interruption operation is performed while the automatic cooking is being executed by the stove burner 21 will be described with reference to the flowcharts shown in FIGS. 4 to 6. The control operation for returning to automatic cooking when automatic cooking is interrupted by turning off the main power of the power switch 43 during automatic cooking is to return to automatic cooking before the ignition operation of the stove point fire extinguishing controller 44. The operation is the same as that when automatic cooking is interrupted by the fire extinguishing operation of the stove point fire extinguishing operator 44, except that it is determined whether or not the power switch 43 is turned on. Therefore, in the following, the case where the automatic cooking is interrupted by the fire extinguishing operation of the stove point fire extinguishing operator 44 will be mainly described as an example during the execution of the automatic cooking.

電源スイッチ４３により主電源のオン操作がなされると（ステップＳＴ１で、Ｙｅｓ）、制御回路５０の主制御プログラムが起動し、各バーナ２１，３１が点火可能な状態となる。 When the main power supply is turned on by the power switch 43 (Yes in step ST1), the main control program of the control circuit 50 is activated, and the burners 21 and 31 are ready to be ignited.

その後、例えば、コンロバーナ２１に対応する設定入力スイッチ４６の調理モード設定スイッチによって自動調理の調理モード等が設定されると、設定された自動調理に応じた加熱時間や火力等の加熱条件が読み込まれ、自動調理モードの制御プログラムが起動される（ステップＳＴ２）。 After that, for example, when the cooking mode of automatic cooking is set by the cooking mode setting switch of the setting input switch 46 corresponding to the stove burner 21, the heating conditions such as the heating time and the heating power according to the set automatic cooking are read. Then, the control program of the automatic cooking mode is started (step ST2).

次いで、対応するコンロ点消火操作子４４で点火操作がなされると（ステップＳＴ３で、Ｙｅｓ）、自動調理を開始させ、設定燃焼時間及び設定加熱時間を計時するためにタイマｔａ、並びに所定の変更制限時間（例えば、９０秒間）内の自動調理の中止や他の調理モードへの変更を可能とするためにタイマｔ０をスタートさせて、所定の点火処理が行われる（ステップＳＴ４〜ＳＴ６）。この点火処理では、点火プラグから火花放電が開始されるとともに、対応するバルブユニット２５の電磁開閉弁及び主弁が開弁され、且つ上記点火操作に連動してニードル弁の開度が所定の点火時開度に調整される。その結果、コンロバーナ２１に設定量のガスが空気とともに供給され、上記火花放電によりコンロバーナ２１が点火される。そして、所定の着火時間が経過するまでに、対応する熱電対２４の出力値が所定の着火検知レベル以上になると、点火プラグからの火花放電を停止させ、自動調理の経過時間が設定燃焼時間（例えば、１０分）に達したか否かの監視を開始させる（ステップＳＴ７）。また、図示しないが、情報表示部４１に調理が終了するまでの残調理時間（設定加熱時間）を表示させる。なお、図示しないが、着火時間が経過しても、熱電対２４の出力値が着火検知レベル未満であれば、点火処理を終了して、情報表示部４１及び音声出力部４２から着火不良を報知させる。 Then, when the ignition operation is performed by the corresponding stove point fire extinguishing actuator 44 (Yes in step ST3), automatic cooking is started, and a timer ta and a predetermined change are made to measure the set combustion time and the set heating time. A predetermined ignition process is performed by starting the timer t0 in order to stop the automatic cooking within the time limit (for example, 90 seconds) or change to another cooking mode (steps ST4 to ST6). In this ignition process, spark discharge is started from the spark plug, the electromagnetic on-off valve and the main valve of the corresponding valve unit 25 are opened, and the opening of the needle valve is set to a predetermined ignition in conjunction with the ignition operation. It is adjusted to the hour opening. As a result, a set amount of gas is supplied to the stove burner 21 together with air, and the stove burner 21 is ignited by the spark discharge. Then, when the output value of the corresponding thermocouple 24 exceeds the predetermined ignition detection level by the time when the predetermined ignition time elapses, the spark discharge from the spark plug is stopped, and the elapsed time of automatic cooking is the set combustion time ( For example, monitoring of whether or not the time has reached (10 minutes) is started (step ST7). Further, although not shown, the information display unit 41 displays the remaining cooking time (set heating time) until the cooking is completed. Although not shown, if the output value of the thermocouple 24 is less than the ignition detection level even after the ignition time has elapsed, the ignition process is terminated and the information display unit 41 and the voice output unit 42 notify the ignition failure. Let me.

自動調理実行中、コンロ点消火操作子４４での消火操作または電源スイッチ４３でのオフ操作のいずれかの自動調理中断操作がなされることなく、自動調理の経過時間が設定燃焼時間に達した場合（ステップＳＴ７で、Ｙｅｓ）、対応するバルブユニット２５の電磁開閉弁を閉じてコンロバーナ２１へのガスの供給を強制的に停止して消火させ、設定加熱時間（設定燃焼時間と設定余熱調理時間（例えば、３０秒間）の合計時間）が経過するまで、自動調理復帰機能を無効とする（ステップＳＴ８〜ＳＴ９）。これにより、余熱調理が開始された後、設定加熱時間に達するまでに、使用者が被調理物の調理状態を確認して、コンロ点消火操作子４４の消火操作または電源スイッチ４３の主電源のオフ操作のいずれかの自動調理中断操作を行った場合（ステップＳＴ１２で、Ｙｅｓ）、自動調理への復帰を喚起する情報表示部４１の表示メッセージや音声出力部４２からの音声は報知されないから、使用者に自動調理が継続している違和感を与えないし、大きな表示や音声による圧迫感も与えない。 When the elapsed time of automatic cooking reaches the set combustion time without performing the automatic cooking interruption operation of either the fire extinguishing operation with the stove point fire extinguishing controller 44 or the off operation with the power switch 43 during automatic cooking execution. (Yes in step ST7), the electromagnetic on-off valve of the corresponding valve unit 25 is closed to forcibly stop the supply of gas to the stove burner 21 to extinguish the fire, and the set heating time (set combustion time and set residual heat cooking time). The automatic cooking return function is disabled until (for example, a total time of 30 seconds) elapses (steps ST8 to ST9). As a result, after the residual heat cooking is started, the user confirms the cooking state of the object to be cooked by the time the set heating time is reached, and the fire extinguishing operation of the stove point fire extinguishing controller 44 or the main power supply of the power switch 43 When any of the automatic cooking interruption operations of the off operation is performed (Yes in step ST12), the display message of the information display unit 41 and the voice from the voice output unit 42 for urging the return to automatic cooking are not notified. It does not give the user a sense of discomfort that automatic cooking is continuing, and does not give a feeling of oppression due to a large display or voice.

余熱調理時間中、自動調理中断操作がなされることなく、設定加熱時間が経過すると、情報表示部４１及び音声出力部４２からそれぞれ、「自動調理が終了した」旨を表示データ及び音声により報知させる。なお、余熱調理時間中に自動調理中断操作がなされた場合、自動調理を終了させる使用者の意図により消火操作等がなされているため、情報表示部４１の全表示をオフにして、運転を終了させる。 During the residual heat cooking time, when the set heating time elapses without performing the automatic cooking interruption operation, the information display unit 41 and the voice output unit 42 notify each of them by display data and voice that "automatic cooking has been completed". .. If the automatic cooking interruption operation is performed during the residual heat cooking time, the fire extinguishing operation or the like is performed by the intention of the user to end the automatic cooking, so all the displays of the information display unit 41 are turned off and the operation is ended. Let me.

一方、自動調理実行中、設定燃焼時間を経過するまでの間に対応するコンロ点消火操作子４４で第１自動調理中断操作である消火操作がなされた場合（ステップＳＴ１１で、Ｙｅｓ）、上記と同様にして、対応するコンロバーナ２１を消火させる（ステップＳＴ２１）。また、コンロバーナ２１が意図せず消火されて自動調理が中断された場合に、第１自動調理中断操作がなされてから第１自動調理復帰操作であるコンロバーナ２１の点火操作がなされるまでの中断時間が復帰制限時間（例えば、１５秒間）内であるかどうかを判定するためにタイマｔ１をスタートさせる（ステップＳＴ２２）。さらに、図示しないが、自動調理への復帰を喚起するために、情報表示部４１や音声出力部４２から「自動調理が中断された」こと、自動調理が取り消されるまでの残り時間（復帰制限時間）、及び自動調理を再開させるための復帰手順（例えば、「自動調理を続ける場合には、１５秒以内に再点火をしてください」）を報知する。 On the other hand, when the fire extinguishing operation, which is the first automatic cooking interruption operation, is performed by the corresponding stove point fire extinguishing controller 44 during the automatic cooking execution until the set combustion time elapses (Yes in step ST11), the above Similarly, the corresponding stove burner 21 is extinguished (step ST21). Further, when the stove burner 21 is unintentionally extinguished and the automatic cooking is interrupted, the operation from the first automatic cooking interruption operation to the ignition operation of the stove burner 21 which is the first automatic cooking return operation is performed. The timer t1 is started to determine whether the interruption time is within the return time limit (for example, 15 seconds) (step ST22). Further, although not shown, in order to arouse the return to automatic cooking, the information display unit 41 and the voice output unit 42 indicate that "automatic cooking has been interrupted" and the remaining time until the automatic cooking is canceled (return time limit). ), And the return procedure for restarting automatic cooking (for example, "If you want to continue automatic cooking, reignite within 15 seconds").

次いで、コンロバーナ２１を再点火して自動調理へ復帰させるために対応するコンロ点消火操作子４４で第１自動調理復帰操作である点火操作がなされると（ステップＳＴ２３で、Ｙｅｓ）、タイマｔ０が変更制限時間内であるかどうかが判定される（ステップＳＴ２４）。タイマｔ０が変更制限時間内であれば（ステップＳＴ２４で、Ｎｏ）、初回の点火から短時間内にコンロ点消火操作子４４で消火操作及び点火操作がなされているから、使用者が誤って自動調理を開始させたと判断できる。このため、自動調理へ復帰させることなく、自動調理モードの制御プログラムから抜け出し、通常の点火処理が行われる（ステップＳＴ２６）。これにより、使用者は、自らの判断により調理を継続させることができる。このとき、情報表示部４１や音声出力部４２から「自動調理を取り消した」旨を報知させてもよい。 Next, when the ignition operation, which is the first automatic cooking return operation, is performed by the corresponding stove point fire extinguishing controller 44 in order to reignite the stove burner 21 and return to automatic cooking (Yes in step ST23), the timer t0. Is determined within the change time limit (step ST24). If the timer t0 is within the change time limit (No in step ST24), the fire extinguishing operation and the ignition operation are performed by the stove point fire extinguishing controller 44 within a short time from the first ignition, so that the user mistakenly automatically performs the fire extinguishing operation and the ignition operation. It can be judged that cooking has started. Therefore, without returning to the automatic cooking, the control program of the automatic cooking mode is exited and the normal ignition process is performed (step ST26). As a result, the user can continue cooking at his / her own discretion. At this time, the information display unit 41 or the voice output unit 42 may notify that "automatic cooking has been canceled".

また、タイマｔ０が変更制限時間を経過している場合、タイマｔ１が復帰制限時間内かどうかが判定される（ステップＳＴ２５）。タイマｔ１が復帰制限時間を経過している場合（ステップＳＴ２５で、Ｎｏ）、所定時間以上の自動調理の中断により被調理物の温度が低下して、自動調理へ復帰させても中断前と同じ加熱条件では加熱不足になる可能性が高い。このため、上記と同様に、自動調理モードの制御プログラムから抜け出し、通常の点火処理が行われる（ステップＳＴ２６）。 Further, when the timer t0 has passed the change time limit, it is determined whether the timer t1 is within the return time limit (step ST25). When the timer t1 has passed the return time limit (No in step ST25), the temperature of the object to be cooked drops due to the interruption of automatic cooking for a predetermined time or longer, and even if the automatic cooking is restored, it is the same as before the interruption. Under heating conditions, there is a high possibility of insufficient heating. Therefore, similarly to the above, the control program of the automatic cooking mode is exited, and the normal ignition process is performed (step ST26).

第１自動調理復帰操作がなされたときに、タイマｔ０が変更制限時間を経過しており、タイマｔ１が復帰制限時間内であれば（ステップＳＴ２４及びＳＴ２５で、Ｙｅｓ）、自動調理が再開され、第１自動調理復帰操作であるコンロバーナ２１の点火操作を行ってからの新たな変更制限時間を計時するために、タイマｔ０をリセットして、新たなタイマｔ０をスタートさせる（ステップＳＴ２７〜ＳＴ２８）。次いで、上記の初回の点火処理と同様にして、コンロバーナ２１の点火処理が行われる（ステップＳＴ２９）。このとき、対応する熱電対２４の出力値が着火検知レベル以上であれば（ステップＳＴ３０で、Ｎｏ）、点火処理を終了させ、自動調理が継続される。 When the first automatic cooking return operation is performed, if the timer t0 has passed the change time limit and the timer t1 is within the return time limit (Yes in steps ST24 and ST25), the automatic cooking is restarted. In order to time a new change time limit after performing the ignition operation of the controller 21 which is the first automatic cooking return operation, the timer t0 is reset and a new timer t0 is started (steps ST27 to ST28). .. Next, the ignition process of the stove burner 21 is performed in the same manner as the first ignition process described above (step ST29). At this time, if the output value of the corresponding thermocouple 24 is equal to or higher than the ignition detection level (No in step ST30), the ignition process is terminated and automatic cooking is continued.

一方、対応する熱電対２４の出力値が着火検知レベル未満であれば（ステップＳＴ３０で、Ｙｅｓ）、情報表示部４１及び音声出力部４２から着火不良を報知させる（ステップＳＴ３１）。この着火不良は第１自動調理復帰操作を行うときに生じるものであるから、ガスコンロ近傍で操作を行っている使用者は直ぐに着火不良が生じたことを認識できる。そして、このような着火不良を認識した使用者は、対応するコンロ点消火操作子４４で第２自動調理中断操作である再消火操作及び第２自動調理復帰操作である再々点火操作を行う（ステップＳＴ４１及びＳＴ４４）。このコンロ点消火操作子４４の再消火操作は、通常、第１自動調理復帰操作がなされてから自動調理復帰機能が無効とされる変更制限時間内の短時間に行われるから、コンロ点消火操作子４４で再々点火操作がなされると、タイマｔ０は変更制限時間内となり、通常の点火処理として実行され、自動調理への復帰が実行されない。 On the other hand, if the output value of the corresponding thermocouple 24 is less than the ignition detection level (Yes in step ST30), the information display unit 41 and the voice output unit 42 notify the ignition failure (step ST31). Since this ignition failure occurs when the first automatic cooking return operation is performed, the user who is operating in the vicinity of the gas stove can immediately recognize that the ignition failure has occurred. Then, the user who recognizes such an ignition failure performs a re-fire extinguishing operation, which is a second automatic cooking interruption operation, and a re-ignition operation, which is a second automatic cooking return operation, with the corresponding stove point fire extinguishing operator 44 (step). ST41 and ST44). Since the re-fire extinguishing operation of the stove point fire extinguishing operation element 44 is usually performed within a short time within the change time limit in which the automatic cooking return function is disabled after the first automatic cooking return operation is performed, the stove point fire extinguishing operation is performed. When the child 44 reignites, the timer t0 is within the change time limit, is executed as a normal ignition process, and is not returned to automatic cooking.

このため、本実施の形態では、第１自動調理復帰操作がなされて自動調理を再開させたとき、対応する熱電対２４の出力値が着火検知レベル未満となり、さらにコンロ点消火操作子４４で第２自動調理中断操作である再消火操作がなされると、新たなタイマｔ１をスタートさせ、さらに第２自動調理復帰操作である再々点火操作がなされると、第１自動調理復帰操作がなされてからの自動調理への復帰を無効とする無効時間である変更制限時間を判定するためのタイマｔ０を計時せず、第２自動調理復帰操作がなされてからの中断時間を計時するタイマｔ１が復帰制限時間内であるかどうかだけを判定する（ステップＳＴ４１〜ＳＴ４５）。これにより、中断時間が復帰制限時間内であれば、自動調理へ復帰させることができる（ステップＳＴ４６）。このとき、図示しないが、情報表示部４１に自動調理が終了するまでの残調理時間を再表示させる。次いで、上記と同様に、点火処理が実行され、自動調理が継続させる。 Therefore, in the present embodiment, when the first automatic cooking return operation is performed and the automatic cooking is restarted, the output value of the corresponding thermoelectric pair 24 becomes less than the ignition detection level, and the timer point fire extinguishing actuator 44 is used for the second. 2 When the re-fire extinguishing operation which is the automatic cooking interruption operation is performed, a new timer t1 is started, and when the re-ignition operation which is the second automatic cooking return operation is performed, the first automatic cooking return operation is performed. The timer t1 for measuring the interruption time after the second automatic cooking return operation is performed without timing the timer t0 for determining the change time limit, which is the invalid time for invalidating the return to automatic cooking, is the return limit. Only the time is determined (steps ST41-ST45). As a result, if the interruption time is within the return time limit, the automatic cooking can be returned (step ST46). At this time, although not shown, the information display unit 41 redisplays the remaining cooking time until the automatic cooking is completed. Next, the ignition process is executed in the same manner as described above, and the automatic cooking is continued.

使用者が第２自動調理復帰操作であるバーナ２１の再々点火操作を行ったが、タイマｔ１が復帰制限時間を経過している場合、自動調理へ復帰させても、設定された加熱条件では被調理物を十分に加熱できなくなる。このため、上記と同様に、自動調理の制御プログラムから抜け出し、通常の点火処理が行われる（ステップＳＴ４８）。このとき、情報表示部４１や音声出力部４２から「自動調理を取り消した」旨を報知させてもよい。 The user performed the re-ignition operation of the burner 21 which is the second automatic cooking return operation, but when the timer t1 has passed the return time limit, even if the automatic cooking is returned, it is subject to the set heating conditions. The cooked food cannot be heated sufficiently. Therefore, in the same manner as described above, the automatic cooking control program is exited and the normal ignition process is performed (step ST48). At this time, the information display unit 41 or the voice output unit 42 may notify that "automatic cooking has been canceled".

以上のように、本実施の形態の加熱調理器は、自動調理中に意図せず点消火操作子４４，４５の消火操作または電源スイッチ４３のオフ操作の自動調理中断操作がなされて自動調理が中断されても、無効時間である変更制限時間経過後で、且つ復帰制限時間内に自動調理復帰操作を行ってバーナ２１，３１を再点火させれば、引き続き自動調理を中断時の状態から再開させる自動調理復帰機能を備えているから、復帰後の残りの加熱時間やバーナ２１，３１の火力を使用者が判断する必要がない。また、上記加熱調理器では、バーナ２１，３１の点火操作がなされて自動調理の開始または再開がされてから変更制限時間を経過するまでは自動調理中断操作が行われても自動調理への復帰を無効とするから、自動調理が誤設定された場合の調理初期の自動調理の中止や加熱条件の設定を変更する時間を確保できる。 As described above, in the cooking cooker of the present embodiment, the automatic cooking is interrupted by the fire extinguishing operation of the point fire extinguishing actuators 44 and 45 or the off operation of the power switch 43 unintentionally during the automatic cooking. Even if it is interrupted, if the burners 21 and 31 are reignited after the change time limit, which is the invalid time, has elapsed and within the return time limit, the automatic cooking will continue to resume from the state at the time of interruption. Since it is equipped with an automatic cooking return function, it is not necessary for the user to judge the remaining heating time after the return and the heating power of the burners 21 and 31. Further, in the above-mentioned cooking cooker, even if the automatic cooking interruption operation is performed from the time when the burners 21 and 31 are ignited and the automatic cooking is started or restarted until the change time limit elapses, the cooking returns to the automatic cooking. Is disabled, so if automatic cooking is set incorrectly, it is possible to secure time to stop automatic cooking at the initial stage of cooking or change the setting of heating conditions.

また、上記のように、第１自動調理復帰操作がなされて自動調理が再開されたときに熱電対２４，３４の起電力が所定の着火検知レベル未満になって、第２自動調理中断操作であるバーナ２１，３１の消火操作がなされると、再開された自動調理が中断される。この第２自動調理中断操作は第１自動調理復帰操作を行うときに生ずるものであるから、ガスコンロ近傍にいる使用者は、自動調理を再開させるための第２自動調理復帰操作であるバーナ２１，３１の点火操作を、通常、第１自動調理復帰操作から短時間内に行う。そのため、第２自動調理復帰操作が第１自動調理復帰操作がなされてからの無効時間内に行われたとき、第１自動調理復帰操作がなされたときと同一の制御動作では、自動調理に復帰させることができないという問題がある。 Further, as described above, when the first automatic cooking return operation is performed and the automatic cooking is restarted, the electromotive force of the thermocouples 24 and 34 becomes less than the predetermined ignition detection level, and the second automatic cooking interruption operation is performed. When the fire extinguishing operation of certain burners 21 and 31 is performed, the restarted automatic cooking is interrupted. Since this second automatic cooking interruption operation occurs when the first automatic cooking return operation is performed, the user in the vicinity of the gas stove can use the burner 21, which is the second automatic cooking return operation for restarting the automatic cooking. The ignition operation of 31 is usually performed within a short time from the first automatic cooking return operation. Therefore, when the second automatic cooking return operation is performed within the invalid time after the first automatic cooking return operation is performed, the automatic cooking is restored in the same control operation as when the first automatic cooking return operation is performed. There is a problem that it cannot be made to do.

しかしながら、上記加熱調理器によれば、第２自動調理中断操作後、第２自動調理復帰操作であるバーナ２１，３１の点火操作がなされると、第１自動調理復帰操作からの無効時間である変更制限時間は計時されず、自動調理への復帰の無効判定が解除されているから、着火不良が生じた場合でも、自動調理へ復帰させることができる。これにより、本実施の形態の加熱調理器は、使用者の使い勝手を向上させることができるとともに、調理の仕上がりのばらつきも抑えることができる。 However, according to the above-mentioned cooking cooker, when the ignition operation of the burners 21 and 31 which is the second automatic cooking return operation is performed after the second automatic cooking interruption operation, it is an invalid time from the first automatic cooking return operation. Since the change time limit is not timed and the invalidity determination for returning to automatic cooking is canceled, it is possible to return to automatic cooking even if ignition failure occurs. As a result, the cooking cooker of the present embodiment can improve the usability of the user and suppress the variation in the cooking finish.

（実施の形態２）
本実施の形態の加熱調理器は、実施の形態１において、第１自動調理復帰操作がなされて自動調理が再開されたときに熱電対２４の起電力が着火検知レベル未満となり、さらに点消火操作子４４，４５で第２自動調理中断操作である再消火操作及び第２自動調理復帰操作である再々点火操作がなされた場合、自動調理へ復帰させるかどうかを判定するにあたって、第１自動調理復帰操作からの変更制限時間内であるかを判定し、さらに第１自動調理中断操作がなされてからの中断時間が復帰制限時間内であるか、また第２自動調理中断操作がなされてからの中断時間が復帰制限時間内であるかを判定する点以外は、上記実施の形態１と同様である。このため、異なる点のみを説明し、同一の部分については説明を省略する。 (Embodiment 2)
In the cooking apparatus of the present embodiment, in the first embodiment, when the first automatic cooking return operation is performed and the automatic cooking is restarted, the electromotive force of the thermoelectric pair 24 becomes less than the ignition detection level, and the point fire extinguishing operation is further performed. When the children 44 and 45 perform the refire extinguishing operation which is the second automatic cooking interruption operation and the reignition operation which is the second automatic cooking return operation, the first automatic cooking return is performed in determining whether to return to the automatic cooking. It is determined whether the change from the operation is within the time limit, and whether the interruption time after the first automatic cooking interruption operation is performed is within the return time limit, or the interruption after the second automatic cooking interruption operation is performed. It is the same as that of the first embodiment except that it is determined whether the time is within the return time limit. Therefore, only the different points will be described, and the same parts will be omitted.

本実施の形態の加熱調理器は、実施の形態１と同様の構成を備えているが、制御回路５０の機能的構成手段として、自動調理実行中、自動調理中断操作が行われるごとに、自動調理中断操作がなされた時間を記憶する中断処理時間記憶部と、実施の形態１の復帰機能無効部の代わりに、第１自動調理中断操作が行われた時点からの経過時間が自動調理を再開可能な所定の復帰制限時間に達したかどうかを判定する第１復帰制限時間計時部と、第２自動調理中断操作が行われた時点からの経過時間が自動調理を再開可能な所定の復帰制限時間に達したかどうかを判定する第２復帰制限時間計時部を備える。 The cooking cooker of the present embodiment has the same configuration as that of the first embodiment, but as a functional configuration means of the control circuit 50, it automatically performs each time an automatic cooking interruption operation is performed during automatic cooking execution. Instead of the interruption processing time storage unit that stores the time when the cooking interruption operation is performed and the return function invalidation unit of the first embodiment, the elapsed time from the time when the first automatic cooking interruption operation is performed resumes automatic cooking. The first return time limit that determines whether or not the possible predetermined return time limit has been reached, and the predetermined return limit that allows the automatic cooking to be resumed for the elapsed time from the time when the second automatic cooking interruption operation is performed. A second return time limit time measuring unit for determining whether or not the time has been reached is provided.

図７〜図９は、本実施の形態の加熱調理器のコンロバーナ２１で自動調理実行中に対応するコンロ点消火操作子４４による消火操作の自動調理中断操作がなされた場合の制御動作を示すフローチャートである。
実施の形態１と同様に、使用者が設定入力スイッチ４６で調理モード等を設定して、自動調理が開始されると、設定燃焼時間が経過するまで、第１自動調理中断操作が行われたかどうかが判定される（ステップＳＴ１０１〜ＳＴ１０７及びＳＴ１１１）。自動調理実行中に第１自動調理中断操作がなされると、復帰制限時間（例えば、１５秒間）を判定するためにタイマｔ１をスタートさせる（ステップＳＴ１２２）。そして、第１自動調理復帰操作がなされたときに、タイマｔ０が変更制限時間（例えば、９０秒間）を経過しているが、タイマｔ１が復帰制限時間内であれば（ステップＳＴ１２４及びＳＴ１２５で、Ｙｅｓ）、自動調理が再開され、第１自動調理復帰操作であるコンロバーナ２１の点火操作を行ってからの新たな変更制限時間を計時するために、タイマｔ０をリセットして、新たなタイマｔ０をスタートさせる（ステップＳＴ１２７〜ＳＴ１２８）。このとき、初回の点火処理と同様に、対応する熱電対２４の出力値が着火検知レベル以上であれば（ステップＳＴ１３０で、Ｎｏ）、点火処理を終了させ、自動調理が継続される。 7 to 9 show a control operation when the automatic cooking interruption operation of the fire extinguishing operation is performed by the corresponding stove point fire extinguishing actuator 44 during the automatic cooking execution by the stove burner 21 of the heating cooker of the present embodiment. It is a flowchart.
Similar to the first embodiment, when the user sets the cooking mode or the like with the setting input switch 46 and the automatic cooking is started, is the first automatic cooking interruption operation performed until the set combustion time elapses? Whether or not it is determined (steps ST101 to ST107 and ST111). When the first automatic cooking interruption operation is performed during the automatic cooking execution, the timer t1 is started to determine the return time limit (for example, 15 seconds) (step ST122). Then, when the first automatic cooking return operation is performed, the timer t0 has passed the change time limit (for example, 90 seconds), but if the timer t1 is within the return time limit (in steps ST124 and ST125, Yes), the timer t0 is reset to time the new change time limit after the automatic cooking is restarted and the ignition operation of the controller 21 which is the first automatic cooking return operation is performed, and the new timer t0 Is started (steps ST127 to ST128). At this time, similarly to the initial ignition process, if the output value of the corresponding thermocouple 24 is equal to or higher than the ignition detection level (No in step ST130), the ignition process is terminated and automatic cooking is continued.

既述したように、対応する熱電対２４の出力値が着火検知レベル未満となると、着火不良を認識した使用者は、対応するコンロ点消火操作子４４で第２自動調理中断操作である再消火操作及び第２自動調理復帰操作である再々点火操作を行う（ステップＳＴ１４１及びＳＴ１４４）。このコンロ点消火操作子４４の再消火操作は、通常、第１自動調理復帰操作がなされてから自動調理復帰機能が無効とされる変更制限時間内の短時間に行われるから、コンロ点消火操作子４４で再々点火操作がなされると、タイマｔ０は変更制限時間内となり、通常の点火処理として実行され、自動調理への復帰が実行されない。 As described above, when the output value of the corresponding thermocouple 24 becomes less than the ignition detection level, the user who recognizes the ignition failure uses the corresponding stove point fire extinguishing controller 44 to refire, which is the second automatic cooking interruption operation. The reignition operation, which is the operation and the second automatic cooking return operation, is performed (steps ST141 and ST144). Since the re-fire extinguishing operation of the stove point fire extinguishing operation element 44 is usually performed within a short time within the change time limit in which the automatic cooking return function is disabled after the first automatic cooking return operation is performed, the stove point fire extinguishing operation is performed. When the child 44 reignites, the timer t0 is within the change time limit, is executed as a normal ignition process, and is not returned to automatic cooking.

このため、本実施の形態では、第１自動調理復帰操作がなされて自動調理を再開させたとき、対応する熱電対２４の出力値が着火検知レベル未満となり、さらにコンロ点消火操作子４４で第２自動調理中断操作である再消火操作がなされると、タイマｔ１をリセットすることなく、復帰制限時間（例えば、１０秒間）を判定するためのタイマｔ２をスタートさせる（ステップＳＴ１４３）。 Therefore, in the present embodiment, when the first automatic cooking return operation is performed and the automatic cooking is restarted, the output value of the corresponding thermocouple 24 becomes less than the ignition detection level, and the stove point fire extinguishing actuator 44 is used for the second. 2 When the refire extinguishing operation, which is an automatic cooking interruption operation, is performed, the timer t2 for determining the return time limit (for example, 10 seconds) is started without resetting the timer t1 (step ST143).

そして、第２自動調理復帰操作である再々点火操作がなされると、第１自動調理復帰操作がなされてからの自動調理への復帰を無効とする無効時間である変更制限時間内であっても、第１自動調理中断操作がなされてからの中断時間を計時するタイマｔ１が復帰制限時間内であれば、自動調理へ復帰させる（ステップＳＴ１４４〜ＳＴ１４６及びＳＴ１４８）。これにより、第１自動調理復帰操作がなされたときに着火不良が生じて、短時間内に第２自動調理復帰操作が行われた場合でも、自動調理へ復帰させることができる。 Then, when the re-ignition operation, which is the second automatic cooking return operation, is performed, even within the change time limit, which is the invalid time for invalidating the return to automatic cooking after the first automatic cooking return operation is performed. If the timer t1 that measures the interruption time after the first automatic cooking interruption operation is performed is within the return time limit, the automatic cooking is restored (steps ST144 to ST146 and ST148). As a result, even if ignition failure occurs when the first automatic cooking return operation is performed and the second automatic cooking return operation is performed within a short time, the automatic cooking can be restored.

また、本実施の形態では、第１自動調理中断操作がなされてからの復帰制限時間を経過していても、第１自動調理中断操作がなされてからの復帰制限時間よりも短時間に設定されている第２自動調理中断操作がなされてからの中断時間を計時するタイマｔ２が復帰制限時間内であれば、自動調理へ復帰させる（ステップＳＴ１４６及びＳＴ１４７）。これにより、使用者の着火不良の認識が遅れた場合でも、自動調理へ復帰させることができる。 Further, in the present embodiment, even if the return time limit after the first automatic cooking interruption operation has elapsed, it is set to be shorter than the return time limit after the first automatic cooking interruption operation is performed. If the timer t2 for measuring the interruption time after the second automatic cooking interruption operation is performed is within the return time limit, the automatic cooking is restored (steps ST146 and ST147). As a result, even if the user's recognition of ignition failure is delayed, it is possible to return to automatic cooking.

なお、タイマｔ０が変更制限時間を経過しており、タイマｔ２が復帰制限時間内である場合（ステップＳＴ１４５及びＳＴ１４７で、Ｙｅｓ）、設定された加熱条件での自動調理を再開させる（ステップＳＴ１４８）。 When the timer t0 has passed the change time limit and the timer t2 is within the return time limit (Yes in steps ST145 and ST147), the automatic cooking under the set heating conditions is restarted (step ST148). ..

第１自動調理復帰操作がなされたときの対応する熱電対２４の出力値が着火検知レベル以上である場合の制御動作は、上記実施の形態１におけるそれと同様である。 The control operation when the output value of the corresponding thermocouple 24 when the first automatic cooking return operation is performed is equal to or higher than the ignition detection level is the same as that in the first embodiment.

以上のように、本実施の形態の加熱調理器は、自動調理中に意図せず点消火操作子４４，４５の消火操作または電源スイッチ４３のオフ操作の自動調理中断操作がなされて自動調理が中断されても、無効時間である変更制限時間経過後で、且つ復帰制限時間内に自動調理復帰操作を行ってバーナ２１，３１を再点火させれば、引き続き自動調理を中断時の状態から再開させる自動調理復帰機能を備えているから、復帰後の残りの加熱時間やバーナ２１，３１の火力を使用者が判断する必要がない。また、上記加熱調理器では、バーナ２１，３１の点火操作がなされて自動調理の開始または再開がされてから変更制限時間が経過するまでは自動調理中断操作が行われても自動調理への復帰を無効とするから、自動調理が誤設定された場合の調理初期の自動調理の中止や加熱条件の設定を変更する時間を確保できる。 As described above, in the cooking cooker of the present embodiment, the automatic cooking is interrupted by the fire extinguishing operation of the point fire extinguishing actuators 44 and 45 or the off operation of the power switch 43 unintentionally during the automatic cooking. Even if it is interrupted, if the burners 21 and 31 are reignited after the change time limit, which is the invalid time, has elapsed and within the return time limit, the automatic cooking will continue to resume from the state at the time of interruption. Since it is equipped with an automatic cooking return function, it is not necessary for the user to judge the remaining heating time after the return and the heating power of the burners 21 and 31. Further, in the above-mentioned cooking cooker, even if the automatic cooking interruption operation is performed from the time when the burners 21 and 31 are ignited and the automatic cooking is started or restarted until the change time limit elapses, the cooking returns to the automatic cooking. Is disabled, so if automatic cooking is set incorrectly, it is possible to secure time to stop automatic cooking at the initial stage of cooking or change the setting of heating conditions.

また、上記のように、第１自動調理復帰操作がなされて自動調理が再開されたときに熱電対２４，３４の起電力が所定の着火検知レベル未満になって、第２自動調理中断操作であるバーナ２１，３１の消火操作がなされると、再開された自動調理が中断される。この第２自動調理中断操作は第１自動調理復帰操作を行うときに生ずるものであるから、ガスコンロ近傍にいる使用者は、自動調理を再開させるための第２自動調理復帰操作であるバーナ２１，３１の点火操作を、通常、第１自動調理復帰操作から短時間内に行う。そのため、第２自動調理復帰操作が第１自動調理復帰操作がなされてからの無効時間内に行われたとき、第１自動調理復帰操作がなされたときと同一の制御動作では、自動調理に復帰させることができないという問題がある。 Further, as described above, when the first automatic cooking return operation is performed and the automatic cooking is restarted, the electromotive force of the thermocouples 24 and 34 becomes less than the predetermined ignition detection level, and the second automatic cooking interruption operation is performed. When the fire extinguishing operation of certain burners 21 and 31 is performed, the restarted automatic cooking is interrupted. Since this second automatic cooking interruption operation occurs when the first automatic cooking return operation is performed, the user in the vicinity of the gas stove can use the burner 21, which is the second automatic cooking return operation for restarting the automatic cooking. The ignition operation of 31 is usually performed within a short time from the first automatic cooking return operation. Therefore, when the second automatic cooking return operation is performed within the invalid time after the first automatic cooking return operation is performed, the automatic cooking is restored in the same control operation as when the first automatic cooking return operation is performed. There is a problem that it cannot be made to do.

しかしながら、上記加熱調理器によれば、第２自動調理中断操作後、第２自動調理復帰操作であるバーナ２１，３１の点火操作がなされると、第１自動調理復帰操作からの無効時間である変更制限時間内であっても、バーナ２１，３１の点火操作が第１自動調理中断操作がなされてからの復帰制限時間内または第２自動調理中断操作がなされてからの復帰制限時間内であれば、自動調理へ復帰させるから、着火不良が生じた場合でも、自動調理へ復帰させることができる。 However, according to the above-mentioned cooking cooker, when the ignition operation of the burners 21 and 31 which is the second automatic cooking return operation is performed after the second automatic cooking interruption operation, it is an invalid time from the first automatic cooking return operation. Even within the change time limit, the ignition operation of the burners 21 and 31 may be within the return time limit after the first automatic cooking interruption operation is performed or within the return time limit after the second automatic cooking interruption operation is performed. For example, since it returns to automatic cooking, it is possible to return to automatic cooking even if ignition failure occurs.

また、上記加熱調理器によれば、第２自動調理中断操作がなされてからの復帰制限時間は、第１自動調理中断操作がなされたときのそれよりも短時間に設定されているから、調理物の温度の低下の少ない状態から自動調理を再開させることができ、食味の低下を抑えることができる。これにより、本実施の形態の加熱調理器は、使用者の使い勝手を向上させることができるとともに、調理の仕上がりのばらつきも抑えることができる。 Further, according to the above-mentioned cooking cooker, the return time limit after the second automatic cooking interruption operation is performed is set to be shorter than that when the first automatic cooking interruption operation is performed, so that cooking is performed. Automatic cooking can be restarted from a state where the temperature of the product does not decrease much, and the decrease in taste can be suppressed. As a result, the cooking cooker of the present embodiment can improve the usability of the user and suppress the variation in the cooking finish.
