次に、このジャー炊飯器の動作について説明する。   Next, operation | movement of this jar rice cooker is demonstrated.

炊飯を行う米とその水量に対応する水を鍋２に入れ、鍋収納部１ａに鍋２を装備し、蓋体８を閉じる。続いて、保温選択ボタン２３で炊飯終了後に引き続き自動的に保温を行うか行わないかを選択する。そして炊飯ボタン２１と押すと炊飯動作開始の信号が制御部５のマイコン５ａへと送られ、炊飯動作を開始する。マイコン５ａは、あらかじめプログラムされた炊飯動作を実行し、底センサー４から送られる鍋２の温度を入力として、底誘導コイル３と蓋誘導コイル１０を最適に通電制御し炊飯を行う。   The rice which cooks rice and the water corresponding to the amount of water are put in the pan 2, the pan 2 is installed in the pan storage portion 1 a, and the lid 8 is closed. Subsequently, it is selected with the heat retention selection button 23 whether or not the heat insulation is to be performed automatically after the end of cooking. When the rice cooking button 21 is pressed, a rice cooking operation start signal is sent to the microcomputer 5a of the control unit 5 to start the rice cooking operation. The microcomputer 5a performs a rice cooking operation programmed in advance, and uses the temperature of the pan 2 sent from the bottom sensor 4 as input, and performs the rice cooking by optimally energizing the bottom induction coil 3 and the lid induction coil 10.

底誘導コイル３に通電すると、底誘導コイル３は鍋２を誘導加熱する。誘導加熱方式は熱効率が良く、熱応答性もよいのでおいしくご飯を炊くことができる。   When the bottom induction coil 3 is energized, the bottom induction coil 3 induction heats the pan 2. The induction heating method has good heat efficiency and good heat response, so you can cook delicious rice.

蓋誘導コイル１０に通電すると蓋誘導コイル１０は金属製の加熱板９を誘導加熱し鍋２を上面から暖める。また炊飯で発生した蒸気が露となって加熱板９へ付着するのを防止する。   When the lid induction coil 10 is energized, the lid induction coil 10 induction-heats the metal heating plate 9 and warms the pan 2 from the upper surface. Moreover, it prevents that the vapor | steam generate | occur | produced by cooking rice becomes dew and adheres to the heating plate 9.

炊飯中に鍋２から発生する蒸気は、加熱板９の加熱板蒸気口２３ａを通過し、蓋蒸気口８ｃを通過して外部へと放出される。ここで、加熱板９と鍋２のフランジ部２ａは鍋パッキン１９でシールされており、また加熱板９と蓋蒸気口８ｃの間は蒸気口パッキン１８でシールされているので、所定の場所以外から蒸気が外部に漏れることのない構造となっている。炊飯中の動作状態は操作基板２０の表示手段２４に表示され、パネル２５の透明部２９と透過して目視できる。   Steam generated from the pan 2 during rice cooking passes through the heating plate steam port 23a of the heating plate 9, passes through the lid steam port 8c, and is discharged to the outside. Here, since the heating plate 9 and the flange portion 2a of the pan 2 are sealed by the pan packing 19, and the space between the heating plate 9 and the lid steam port 8c is sealed by the steam port packing 18, other than a predetermined place. The structure prevents steam from leaking outside. The operating state during rice cooking is displayed on the display means 24 of the operation board 20 and can be seen through the transparent portion 29 of the panel 25.

炊飯が終了すると、炊飯開始前に保温選択ボタン２３で引き続き保温を自動的に行うよう選択した場合は、マイコン５ａは炊飯に続き保温の動作を実行する。そうでない場合は炊飯終了と同時に動作を停止する。   When rice cooking is completed, if it is selected that the heat insulation selection button 23 automatically continues the heat insulation before starting the rice cooking, the microcomputer 5a performs the heat insulation operation following the rice cooking. Otherwise, the operation is stopped simultaneously with the end of cooking.

本実施の形態のようにすることで、炊飯終了後、保温する必要がない場合に不要な電力消費をなくすことができる。   By carrying out like this Embodiment, when it is not necessary to heat-retain after completion | finish of rice cooking, unnecessary power consumption can be eliminated.

（実施の形態２）
本実施の形態において、図３に示すように操作基板３０には炊飯ボタン３１と保温ボタン３２と保温選択ボタン３３と保温時間選択ボタン３４と報知音発生手段３５と表示手段３６が設けられており、その他の構成については実施の形態１と同じである。 (Embodiment 2)
In the present embodiment, as shown in FIG. 3, the operation board 30 is provided with a rice cooking button 31, a heat retention button 32, a heat retention selection button 33, a heat retention time selection button 34, a notification sound generating means 35, and a display means 36. Other configurations are the same as those in the first embodiment.

次に、このジャー炊飯器の動作について説明する。   Next, operation | movement of this jar rice cooker is demonstrated.

炊飯を行う米とその水量に対応する水を鍋に入れ、鍋収納部に鍋２を装備し、蓋体８を閉じるまでは実施の形態１と同様である。続いて、保温選択ボタン３３で炊飯終了後に引き続き自動的に保温を行うか行わないかを選択する。そして、保温時間選択ボタン３４で保温を行いたい時間を設定する。つづいて炊飯ボタン３１を押すと炊飯動作開始の信号が制御部のマイコンへと送られ、炊飯動作を開始する。   It is the same as that of Embodiment 1 until the rice which cooks rice and the water corresponding to the amount of water are put into a pan, the pan 2 is equipped with the pan 2 and the lid 8 is closed. Subsequently, it is selected whether or not to automatically keep the heat after the end of cooking with the heat keeping selection button 33. And the time which wants to keep heat with the heat retention time selection button 34 is set. When the rice cooking button 31 is subsequently pressed, a rice cooking operation start signal is sent to the microcomputer of the control unit, and the rice cooking operation is started.

炊飯終了時、引き続き自動的に保温を行うように選択した場合、炊飯前に保温時間選択ボタン３４で設定した時間だけ保温動作を実行するとともに、保温動作中は残り何時間保温動作を実行するかという保温残時間表示を表示手段に表示する。そして保温動作終了時に報知音発生手段３５は報知音を発生し、保温動作終了を使用者に報知する。   If you choose to continue warming automatically at the end of cooking, the warming operation will be performed for the time set with the warming time selection button 34 before cooking, and how many remaining warming operations will be performed during the warming operation. Is displayed on the display means. At the end of the heat retaining operation, the notification sound generating means 35 generates a notification sound to notify the user of the end of the heat retaining operation.

また、保温動作のみ実行する場合においては、保温時間選択ボタンで保温時間を選択し、つづいて保温ボタン３２を押すと、選択した時間のみ保温動作を実行するとともに保温動作中は残り何時間保温動作を実行するかという保温残時間表示を表示手段に表示する。そして同様に保温動作終了時には報知音発生手段３５は報知音を発生し、保温動作終了を使用者に報知する。   In addition, when only the warming operation is performed, when the warming time is selected with the warming time selection button and then the warming button 32 is pressed, the warming operation is performed only for the selected time and the remaining warming operation is performed during the warming operation. Is displayed on the display means. Similarly, at the end of the heat retaining operation, the notification sound generating means 35 generates a notification sound and notifies the user of the end of the heat retaining operation.

本実施の形態のようにすることで、炊飯後に数時間のみ保温したい場合、あるいは保温のみしたい場合においても、切り忘れの場合に無駄な電力消費をなくすことができる。残り何時間保温動作を実行するかを認識できるので必要に応じて保温時間を延長するなどが可能となる。そして使用者が保温動作を継続したいにもかかわらず、保温動作が終了した場合に炊飯器を確認せずとも保温動作終了を認知することが保温動作の再実行が可能となる。   By making it like this Embodiment, even when it wants to keep heat only for several hours after cooking rice, or when it wants to keep only heat, wasteful power consumption can be eliminated in the case of forgetting to cut. Since it is possible to recognize how many hours of heat insulation operation will be performed, it is possible to extend the heat insulation time as necessary. And although a user wants to continue heat retention operation | movement, when heat retention operation | movement is complete | finished, re-execution of heat retention operation | movement can be performed to recognize completion | finish of heat retention operation | movement, without confirming a rice cooker.

（実施の形態３）
本実施の形態において、図４に示すように底センサーと鍋収納部の間にはご飯量検知手段４１がある。その他の構成については実施の形態１と同じである。 (Embodiment 3)
In the present embodiment, as shown in FIG. 4, there is a rice amount detection means 41 between the bottom sensor and the pan storage part. Other configurations are the same as those in the first embodiment.

ご飯の入った状態で鍋をセットすると、ご飯と鍋の重量によりご飯量検知手段４１は下方に圧接され、鍋内のご飯の重量を測定することができる。そして保温選択ボタンで炊飯終了後に引き続き自動的に保温を行うように設定し炊飯・保温を行ったとき、ご飯量検知手段４１によりご飯がなくなったと判断した場合は、保温動作を停止する。   When the pan is set in a state where the rice is contained, the rice amount detecting means 41 is pressed downward by the weight of the rice and the pan, and the weight of the rice in the pan can be measured. And when it sets so that it may continue to heat automatically after completion | finish of rice cooking with a heat retention selection button, and rice cooking and heat insulation are carried out, when it is judged by the rice amount detection means 41 that rice has run out, a heat insulation operation | movement will be stopped.

本例のようにすることで、確実に不要な保温による電力消費の無駄をなくすことができるに加え、自動的に保温動作を停止するので使い勝手がよくなる。   In this example, power consumption due to unnecessary heat retention can be surely eliminated, and the heat retention operation is automatically stopped, so that the usability is improved.

また、保温選択ボタンで保温をしないように設定した場合において、場合によっては鍋内のご飯を食べきれずに、炊飯終了後に数時間経過してもご飯が残る場合もある。このような場合、鍋内のご飯に結露してべちょべちょになったり、腐敗して食べられなくなったりする恐れがあるが、本実施の形態のジャー炊飯器では、炊飯終了から所定時間後に鍋内にご飯があると検知した場合は、保温動作を実行し、残ったご飯に結露してべちょべちょになったり、腐敗したりするのを防止する。ここで所定時間後とは、炊飯終了後およそ４時間程度経過した時点が、ごはんは幾分まだ温かく、かつ炊飯直後の食事も終了している場合が多く、適切である。そして保温動作の実行開始時にご飯の温度を通常の保温温度より幾分高めるとご飯への結露の防止や腐敗の防止には効果的である。ここで、通常の保温温度が７０℃程度であるので、保温動作実行開始時のご飯温度は７５℃から８０℃程度に高めるのが適切である。   Moreover, when it sets so that it may not heat-retain with a heat-retaining selection button, the rice in a pot may not be eaten depending on the case, and rice may remain even if several hours pass after cooking rice. In such a case, there is a risk of condensation on the rice in the pan, or it may rot and become unusable, but in the jar rice cooker of this embodiment, a predetermined time after the end of cooking When it detects that there is rice in the pan, it performs a warming operation to prevent the remaining rice from condensing and rotting. Here, the term “after a predetermined time” is appropriate when about 4 hours have passed since the end of cooking, and the rice is still somewhat warm and the meal immediately after cooking is often completed. If the temperature of the rice is raised somewhat higher than the normal temperature at the start of execution of the heat retaining operation, it is effective for preventing condensation on the rice and preventing spoilage. Here, since the normal heat retention temperature is about 70 ° C, it is appropriate to increase the rice temperature at the start of the heat retention operation from 75 ° C to about 80 ° C.

以上のように、本発明にかかるジャー炊飯器は、炊飯終了後、保温する必要がない場合に不要な電力消費をなくし、かつ保温動作の切り忘れの場合に無駄な電力消費をなくすことができる。   As described above, the jar rice cooker according to the present invention can eliminate unnecessary power consumption when it is not necessary to keep warm after the completion of rice cooking, and can eliminate wasteful power consumption when forgetting to turn off the warming operation.
