第４の発明は、複数段階に設定火力を切り替えて被加熱物の加熱を行う加熱手段と、予め定めた被加熱物の制御温度を検知する複数の温度検知手段と、前記温度検知手段の故障を検知するセンサ故障検知手段と、前記複数の温度検知手段が被加熱物の制御温度を検知することにより被加熱物の加熱制御をする制御手段とを備え、前記制御手段は、複数の温度検知手段のうち、少なくとも一つの温度検知手段が故障したことを前記センサ故障検知手段で検知した場合には、複数段階の設定火力をそれぞれ当初よりも低い設定火力に再設定するようにした加熱調理器としたことにより、故障していない温度検知手段を用いて温度検知しても、複数段階の設定火力をそれぞれ当初よりも低い設定火力に再設定することで、被加熱物は異常高温になることなく故障前と同等の温度で制御でき、安全に使用することができるものである。   According to a fourth aspect of the present invention, there is provided a heating means for heating an object to be heated by switching a set heating power in a plurality of stages, a plurality of temperature detecting means for detecting a predetermined control temperature of the object to be heated, and a failure of the temperature detecting means.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１、図２は、本発明の実施の形態１における加熱調理器を示すものである。 (Embodiment 1)
1 and 2 show a cooking device according to Embodiment 1 of the present invention.

図１は誘導加熱調理器を示したものであり、鍋等の被加熱物１を載置するトッププレート２と、トッププレート２の下方に設けられ被加熱物１を誘導加熱する加熱手段である加熱コイル３を備えている。また、商用電源４を直流に変換する整流器５と、整流器５で整流した直流を、スイッチング素子６ａをオンオフさせて加熱コイル３に高周波電流を供給するインバータ６と、スイッチング素子６ａを駆動する駆動手段７と、被加熱物１の温度を測定する第１、第２の温度検知手段８、９と、第１、第２の温度検知手段８、９の故障を検知するセンサ故障検知手段１０と、第１、第２の温度検知手段８、９の検知温度に応じてスイッチング素子６ａのオン時間を制御する制御手段１１と、第１、第２の温度検知手段８、９の故障を音、音声、光あるいは文字、記号等で報知する報知手段１２をも備えている。   FIG. 1 shows an induction heating cooker, which is a top plate 2 on which a heated object 1 such as a pan is placed, and heating means that is provided below the top plate 2 and induction-heats the heated object 1. A heating coil 3 is provided. Further, a rectifier 5 that converts the commercial power source 4 into direct current, an inverter 6 that supplies the high-frequency current to the heating coil 3 by turning on and off the switching element 6a of the direct current rectified by the rectifier 5, and driving means that drives the switching element 6a 7, first and second temperature detecting means 8 and 9 for measuring the temperature of the object to be heated 1, and sensor failure detecting means 10 for detecting a failure of the first and second temperature detecting means 8 and 9, The control means 11 for controlling the ON time of the switching element 6a according to the detected temperatures of the first and second temperature detecting means 8 and 9, and the failure of the first and second temperature detecting means 8 and 9 are sounded and voiced. Also provided is an informing means 12 for informing with light, characters, symbols or the like.

前記第１、第２の温度検知手段８、９は、予め定めた被加熱物１の制御温度（所定の一定温度）を検知するものである。そして、第１、第２の温度検知手段８、９が被加熱物１の制御温度を検知することにより、制御手段１１は被加熱物１の加熱を停止または火力低下をさせる。なお、第１、第２の温度検知手段８、９の温度追随性は、その設置場所が異なることにより、異なるものである。また、制御手段１１は、第１、第２の温度検知手段８、９のうち、一つの温度検知手段８が故障したことを前記センサ故障検知手段１０で検知した場合には、被加熱物１の制御温度を当初の設定よりも低く再設定するようにしているものである。   The first and second temperature detecting means 8 and 9 are for detecting a predetermined control temperature (predetermined constant temperature) of the article 1 to be heated. And when the 1st, 2nd temperature detection means 8 and 9 detect the control temperature of the to-be-heated object 1, the control means 11 stops the heating of the to-be-heated object 1, or makes a thermal power fall. In addition, the temperature followability of the 1st, 2nd temperature detection means 8 and 9 changes with the installation locations differing. In addition, when the sensor failure detection unit 10 detects that one of the first and second temperature detection units 8 and 9 has failed, the control unit 11 detects the heated object 1. The control temperature is reset to be lower than the initial setting.

図２は調理時における被加熱物１の温度推移を示している。   FIG. 2 shows the temperature transition of the heated object 1 during cooking.

鍋等の被加熱物１は、駆動手段７が設定火力に応じた所定時間でスイッチング素子６ａを駆動し、商用電源４を整流器５で整流した直流を高周波電流に変換して、加熱コイル３により誘導加熱される。ここで、インバータ６はスイッチング素子６ａのオン時間が長いほどインバータ６への入力が大きくなる特性を有している。   The heated object 1 such as a pan drives the switching element 6a for a predetermined time corresponding to the set heating power by the driving means 7 and converts the direct current rectified by the rectifier 5 into a high frequency current by the heating coil 3. Induction heating. Here, the inverter 6 has a characteristic that the input to the inverter 6 becomes larger as the ON time of the switching element 6a is longer.

被加熱物１の温度は、第１、第２の温度検知手段８、９で検知されており、本実施の形態では、ｔ１後に、第１の温度検知手段８が予め定めた被加熱物１の制御温度Ｔｏｈｐ（所定の一定温度）に達すると、制御手段１１がオン時間零、つまりスイッチング素子６ａの駆動を停止する信号を駆動手段７に出力し、被加熱物１の加熱が停止される。この場合の被加熱物１の温度推移は、被加熱物温度Ａのようになり、被加熱物１の最高温度はＴ１となる。ところが、第１の温度検知手段８が故障すると、ｔ２後に、第２の温度検知手段９の検知温度がＴｏｈｐに達して、加熱を停止させても、被加熱物温度Ｂのようになり、被加熱物１の最高温度はＴ２まで達することになる。   The temperature of the object to be heated 1 is detected by the first and second temperature detecting means 8 and 9, and in the present embodiment, the object 1 to be heated is predetermined by the first temperature detecting means 8 after t1. When the control temperature Tohp (predetermined constant temperature) is reached, the control means 11 outputs a signal for stopping the driving of the switching element 6a to the driving means 7 when the ON time is zero, and the heating of the article 1 to be heated is stopped. . In this case, the temperature transition of the object to be heated 1 becomes the object temperature A to be heated, and the maximum temperature of the object to be heated 1 is T1. However, if the first temperature detecting means 8 fails, the temperature detected by the second temperature detecting means 9 reaches Tohp after t2, and even if the heating is stopped, the temperature of the object to be heated becomes B. The maximum temperature of the heated object 1 reaches T2.

しかしながら、本実施の形態では、第１の温度検知手段８が故障したことをセンサ故障検知手段１０で検知した場合には、被加熱物１の制御温度ＴｏｈｐをＴｏｈｐ２へ当初よりも低く再設定するようにしたので、第２の温度検知手段９の検知温度がＴｏｈｐ２へ達して火力を低下しても、被加熱物温度Ｂのようにはならず、被加熱物温度Ａのように被加熱物１の最高温度はＴ１となり、第１の温度検知手段８で制御した場合とほぼ同じになる。   However, in the present embodiment, when the sensor failure detection unit 10 detects that the first temperature detection unit 8 has failed, the control temperature Tohp of the article to be heated 1 is reset to Tohp2 lower than the original. Therefore, even if the detected temperature of the second temperature detecting means 9 reaches Tohp2 and the thermal power is reduced, the heated object temperature B does not become the same as the heated object temperature B, but the heated object The maximum temperature of 1 is T1, which is almost the same as that controlled by the first temperature detecting means 8.

このように、第２の温度検知手段９を用いて温度検知しても、被加熱物１の制御温度をＴｏｈｐからＴｏｈｐ２へ当初よりも低く再設定することで、被加熱物１は異常高温になることなく故障前と同等の温度で制御でき、安全に使用することができるものである。   In this way, even if the temperature is detected using the second temperature detecting means 9, the object 1 to be heated becomes an abnormally high temperature by resetting the control temperature of the object 1 to be lowered from Tohp to Tohp2. Therefore, it can be controlled at the same temperature as before the failure and can be used safely.

なお、本実施の形態では、加熱コイルを用いた誘導加熱調理器としたが、ラジェントヒータやシーズヒータ、ハロゲンヒータ等の加熱手段を用いた加熱調理器でも同様の効果が得られる。また、温度検知手段としては、第１、第２の温度検知手段８、９の２つに限られるものではなく、それ以上であってもよいものである。   In this embodiment, the induction heating cooker using the heating coil is used. However, the same effect can be obtained with a heating cooker using heating means such as a radiant heater, a sheathed heater, or a halogen heater. Further, the temperature detecting means is not limited to the first and second temperature detecting means 8 and 9, but may be more than that.

（実施の形態２）
次に、図１、図３により、本発明の実施の形態２における加熱調理器について説明する。 (Embodiment 2)
Next, the cooking device in Embodiment 2 of this invention is demonstrated with FIG. 1, FIG.

本実施の形態においては、複数段階の設定火力Ｐ２またはＰ１を順次切り替えて被加熱物１の加熱を行う加熱コイル３（加熱手段）と、設定火力Ｐ２またはＰ１毎に予め定めた被加熱物１の制御温度Ｔｌ１、Ｔｈ１を検知する複数の温度検知手段８、９と、前記温度検知手段８、９の故障を検知するセンサ故障検知手段１０と、前記複数の温度検知手段８、９が被加熱物１の制御温度Ｔｌ１、Ｔｈ１を検知することにより被加熱物１の加熱制御をする制御手段１１とを備え、前記制御手段１１は、複数の温度検知手段８、９のうち、一つの温度検知手段８が故障したことを前記センサ故障検知手段１０で検知した場合には、設定火力Ｐ２またはＰ１毎に予め定めた被加熱物１の制御温度Ｔｌ１、Ｔｈ１をそれぞれＴｌ２、Ｔｈ２と当初よりも低く再設定するようにしたものである。   In the present embodiment, a heating coil 3 (heating means) that heats the article to be heated 1 by sequentially switching a plurality of stages of setting thermal power P2 or P1, and an article to be heated 1 that is predetermined for each set thermal power P2 or P1. A plurality of temperature detection means 8, 9 for detecting the control temperatures Tl1, Th1, a sensor failure detection means 10 for detecting a failure of the temperature detection means 8, 9, and the plurality of temperature detection means 8, 9 being heated. And a control means 11 for controlling the heating of the article to be heated 1 by detecting the control temperatures Tl1 and Th1 of the object 1, and the control means 11 is one of the plurality of temperature detection means 8 and 9. When the sensor failure detection means 10 detects that the means 8 has failed, the control temperatures Tl1 and Th1 of the heated object 1 predetermined for each set heating power P2 or P1 are set to Tl2 and Th2, respectively. Ku is obtained so as to re-set.

図３は調理時における被加熱物１の温度推移を示している。   FIG. 3 shows the temperature transition of the heated object 1 during cooking.

鍋等の被加熱物１は、実施の形態１と同様にして、加熱コイル３により誘導加熱される。ここで、被加熱物１の温度は、第１、第２の温度検知手段８、９で検知されている。本実施の形態では、Ａの設定火力Ｐ２で加熱し、ｔ１後に、第１の温度検知手段８が予め定めた被加熱物１の制御温度Ｔ１１に達すると、制御手段１１は、設定火力Ｐ２からＰ１へ火力を低減する。更に、ｔｍ１後に、設定火力Ｐ１の制御温度Ｔｈ１を検知すると、制御手段１１がオン時間零、つまりスイッチング素子６ａの駆動を停止する信号を駆動手段７に出力し、被加熱物１の加熱が停止される。この場合の被加熱物１の温度推移は、被加熱物温度Ａのようになり、被加熱物１の最高温度はＴ１となる。ところが、第１の温度検知手段８が故障すると、ｔ２後に、第２の温度検知手段９の検知温度がＴ１１に達して、Ｂの設定火力Ｐ２からＰ１へ火力を低減させ、ｔｍ２後に、被加熱物１の加熱を停止させても、被加熱物温度Ｂのようになり、被加熱物１の最高温度はＴ２まで達することになる。   The heated object 1 such as a pot is induction-heated by the heating coil 3 in the same manner as in the first embodiment. Here, the temperature of the article 1 to be heated is detected by the first and second temperature detecting means 8 and 9. In the present embodiment, heating is performed with the set thermal power P2 of A, and after t1, when the first temperature detection means 8 reaches the predetermined control temperature T11 of the heated object 1, the control means 11 starts from the set thermal power P2. Reduce firepower to P1. Furthermore, when the control temperature Th1 of the set thermal power P1 is detected after tm1, the control means 11 outputs a signal to the drive means 7 that the on-time is zero, that is, the drive of the switching element 6a is stopped, and the heating of the article 1 to be heated is stopped. Is done. In this case, the temperature transition of the object to be heated 1 becomes the object temperature A to be heated, and the maximum temperature of the object to be heated 1 is T1. However, if the first temperature detecting means 8 fails, the temperature detected by the second temperature detecting means 9 reaches T11 after t2, the thermal power is reduced from the set thermal power P2 of P to P1, and after tm2, Even if the heating of the object 1 is stopped, the object temperature B is reached, and the maximum temperature of the object 1 reaches T2.

しかしながら、本実施の形態では、第１の温度検知手段８が故障したことをセンサ故障検知手段１０で検知した場合には、設定火力Ｐ２またはＰ１毎の制御温度をＴｌ１よりＴｌ２、Ｔｈ１よりＴｈ２に当初よりも低く再設定するようにしたので、被加熱物１の温度上昇が緩やかになる。そのため、被加熱物１の最高温度はＴ２より低いＴ１となり、第１の温度検知手段８で制御した場合とほぼ同じになる。   However, in the present embodiment, when the sensor failure detection unit 10 detects that the first temperature detection unit 8 has failed, the control temperature for each set thermal power P2 or P1 is changed from Tl1 to Tl2, and from Th1 to Th2. Since the resetting is performed lower than the initial setting, the temperature rise of the article 1 to be heated becomes moderate. Therefore, the maximum temperature of the object to be heated 1 is T1 lower than T2, which is almost the same as that controlled by the first temperature detecting means 8.

このように、第２の温度検知手段９を用いて温度検知しても、設定火力Ｐ２またはＰ１毎に予め定めた被加熱物１の制御温度Ｔｌ１、Ｔｈ１をそれぞれＴｌ２、Ｔｈ２と当初よりも低く再設定することで、被加熱物１は異常高温になることなく故障前と同等の温度で制御でき、安全に使用することができるものである。   Thus, even if the temperature is detected using the second temperature detecting means 9, the control temperatures Tl1 and Th1 of the heated object 1 predetermined for each set thermal power P2 or P1 are lower than the initial values of Tl2 and Th2, respectively. By resetting, the object to be heated 1 can be controlled at the same temperature as before the failure without becoming abnormally high temperature, and can be used safely.

なお、本実施の形態では、設定火力及び制御温度を２段階で構成したが、３段階以上でも同様の効果が得られるものである。また、温度検知手段としては、第１、第２の温度検知手段８、９の２つに限られるものではなく、それ以上であってもよいものである。   In this embodiment, the set thermal power and the control temperature are configured in two stages, but the same effect can be obtained even in three or more stages. Further, the temperature detecting means is not limited to the first and second temperature detecting means 8 and 9, but may be more than that.

本実施の形態においては、複数段階に設定火力Ｐ２からＰ１に切り替えて被加熱物１の加熱を行うことが可能な加熱コイル３（加熱手段）と、予め定めた被加熱物１の制御温度Ｔｏｈｐを検知する複数の温度検知手段８、９と、前記温度検知手段８、９の故障を検知するセンサ故障検知手段１０と、前記複数の温度検知手段８、９が被加熱物１の制御温度Ｔｏｈｐを検知することにより被加熱物１の加熱制御をする制御手段１３とを備え、前記制御手段１３は、複数の温度検知手段８、９のうち、一つの温度検知手段８が故障したことを前記センサ故障検知手段１０で検知した場合には、設定火力Ｐ２からＰ１へ設定火力を当初よりも低い設定火力に再設定するようにしたものである。   In the present embodiment, the heating coil 3 (heating means) capable of heating the object to be heated 1 by switching from the set thermal power P2 to P1 in a plurality of stages, and a predetermined control temperature Tohp of the object to be heated 1 A plurality of temperature detection means 8 and 9 for detecting the failure, a sensor failure detection means 10 for detecting a failure of the temperature detection means 8 and 9, and the plurality of temperature detection means 8 and 9 are controlled by the control temperature Tohp of the object 1 to be heated. Control means 13 for controlling the heating of the article 1 to be heated, and the control means 13 indicates that one of the temperature detection means 8, 9 is out of order. When detected by the sensor failure detection means 10, the set heat power is reset from the set heat power P2 to P1 to a set heat power lower than the initial heat power.

図４は調理時における被加熱物１の温度推移を示している。   FIG. 4 shows the temperature transition of the heated object 1 during cooking.

鍋等の被加熱物１は、実施の形態１と同様にして、加熱コイル３により誘導加熱される。ここで、被加熱物１の温度は、第１、第２の温度検知手段８、９で検知されている。本実施の形態では、Ａの設定火力Ｐ２で加熱し、第１の温度検知手段８が予め定めた被加熱物１の制御温度Ｔｏｈｐを検知すると、制御手段１１は被加熱物１の加熱を停止するものである。この場合の被加熱物１の温度推移は、被加熱物温度Ａのようになる。ところで、第１の温度検知手段８が故障したことをセンサ故障検知手段１０で検知した場合には、設定火力Ｐ２からＢの設定火力Ｐ１へ当初よりも低く再設定することにより、被加熱物１の温度上昇は緩やかになり、温度制御によって加熱が停止された後の温度上昇も低くなる。すなわち、被加熱物温度Ｂのようになり、被加熱物１の最高温度は低く抑えられる。   The heated object 1 such as a pot is induction-heated by the heating coil 3 in the same manner as in the first embodiment. Here, the temperature of the article 1 to be heated is detected by the first and second temperature detecting means 8 and 9. In the present embodiment, heating is performed with the set heating power P2 of A, and when the first temperature detecting means 8 detects the control temperature Tohp of the object 1 to be heated, the control means 11 stops heating the object 1 to be heated. To do. In this case, the temperature transition of the object to be heated 1 becomes the object temperature A to be heated. By the way, when the sensor failure detecting means 10 detects that the first temperature detecting means 8 has failed, it is reset from the set thermal power P2 to the set thermal power P1 of B lower than the original, thereby the object to be heated 1 The temperature rise is moderate, and the temperature rise after heating is stopped by temperature control is also reduced. That is, it becomes like the to-be-heated object temperature B, and the maximum temperature of the to-be-heated object 1 is suppressed low.

このように、第２の温度検知手段９を用いて温度検知しても、設定火力Ｐ２からＰ１へ当初よりも低い設定火力に再設定することで、被加熱物１は異常高温になることなく故障前と同等の温度で制御でき、安全に使用することができるものである。なお、実施の形態１と同様、温度検知手段としては、第１、第２の温度検知手段８、９の２つに限られるものではなく、それ以上であってもよいものである。   In this way, even if the temperature is detected using the second temperature detection means 9, the heated object 1 does not reach an abnormally high temperature by resetting the setting heating power P <b> 2 to the setting heating power P <b> 1 lower than the initial setting. It can be controlled at the same temperature as before failure and can be used safely. As in the first embodiment, the temperature detection means is not limited to the first and second temperature detection means 8 and 9, and may be more than that.

（実施の形態４）
次に、図４、図６により、本発明の実施の形態４における加熱調理器について説明する。 (Embodiment 4)
Next, the cooking device in Embodiment 4 of this invention is demonstrated with FIG. 4, FIG.

本実施の形態においては、複数段階に設定火力Ｐ２からＰ１に切り替えて被加熱物１の加熱を行う加熱コイル３（加熱手段）と、予め定めた被加熱物１の制御温度Ｔｏ、Ｔｏｈｐを検知する複数の温度検知手段８、９と、前記温度検知手段８、９の故障を検知するセンサ故障検知手段１０と、前記複数の温度検知手段８、９が被加熱物１の制御温度Ｔｏ、Ｔｏｈｐを検知することにより被加熱物１の加熱制御をする制御手段１３とを備え、前記制御手段１３は、複数の温度検知手段８、９のうち、一つの温度検知手段８が故障したことを前記センサ故障検知手段１０で検知した場合には、複数段階の設定火力Ｐ２からＰ１へＰａ２からＰａ１へそれぞれ当初よりも低い設定火力に再設定するようにしたものである。   In the present embodiment, the heating coil 3 (heating means) that heats the object to be heated 1 by switching from the set thermal power P2 to P1 in a plurality of stages, and predetermined control temperatures To and Tohp of the object to be heated 1 are detected. A plurality of temperature detection means 8 and 9, a sensor failure detection means 10 for detecting a failure of the temperature detection means 8 and 9, and the plurality of temperature detection means 8 and 9 are controlled by the control temperatures To and Tohp of the article 1 to be heated. Control means 13 for controlling the heating of the article 1 to be heated, and the control means 13 indicates that one of the temperature detection means 8, 9 is out of order. When detected by the sensor failure detection means 10, the setting thermal power is reset from a plurality of stages to the lower setting heat power from the initial setting P2 to P1 and from Pa2 to Pa1, respectively.

図６は調理時における被加熱物１の温度推移を示している。   FIG. 6 shows the temperature transition of the heated object 1 during cooking.

鍋等の被加熱物１は、実施の形態１と同様にして、加熱コイル３により誘導加熱される。ここで、被加熱物１の温度は、第１、第２の温度検知手段８、９で検知されている。本実施の形態では、Ａの設定火力Ｐ２で加熱し、第１の温度検知手段８が予め定めた被加熱物１の制御温度Ｔｏを検知すると、設定火力をＰ１に切り替え、制御温度Ｔｏｈｐで被加熱物１の加熱を停止するものである。この場合の被加熱物１の温度推移は、被加熱物温度Ａのようになる。ところで、第１の温度検知手段８が故障したことをセンサ故障検知手段１０で検知した場合には、設定火力Ｐ２からＢの設定火力Ｐａ２へ、そしてＰａ１へと当初よりも低い設定火力に再設定することにより、被加熱物１の温度上昇は緩やかになり、温度制御によって加熱が停止された後の温度上昇も低くなる。すなわち、被加熱物温度Ｂのようになり、被加熱物１の最高温度は低く抑えられる。   The heated object 1 such as a pot is induction-heated by the heating coil 3 in the same manner as in the first embodiment. Here, the temperature of the article 1 to be heated is detected by the first and second temperature detecting means 8 and 9. In the present embodiment, when heating is performed with the set thermal power P2 of A and the first temperature detection means 8 detects the control temperature To of the object 1 to be heated, the set thermal power is switched to P1, and the target temperature is controlled at the control temperature Tohp. The heating of the heated object 1 is stopped. In this case, the temperature transition of the object to be heated 1 becomes the object temperature A to be heated. By the way, when it is detected by the sensor failure detection means 10 that the first temperature detection means 8 has failed, the set thermal power is reset from the set thermal power P2 to the set thermal power Pa2 of B, and then to Pa1. By doing so, the temperature rise of the article 1 to be heated becomes moderate, and the temperature rise after the heating is stopped by the temperature control is also lowered. That is, it becomes like the to-be-heated object temperature B, and the maximum temperature of the to-be-heated object 1 is suppressed low.

なお、本実施の形態においては、第１の温度検知手段８が故障したことをセンサ故障検知手段１０が検知した場合、加熱開始から一定時間は、故障前の加熱火力Ｐ２、Ｐ１で加熱を行い、一定時間経過後、加熱火力をＰａ２、Ｐａ１へ下げて、同様の火力制御を行うように配慮している。すなわち、設定火力を当初よりも低く切り替えるタイミングは、センサ故障検知手段１０による温度検知手段８の故障検知後、一定時間後に行うことによって、炒め物調理等、高火力を必要とする場合、加熱開始後、被加熱物１の温度が十分に上昇するまでの立ち上がり時の加熱火力は故障前と同様とし、被加熱物１の温度が上昇した後は、異常高温を防ぐために加熱火力を低下させるようにしている。   In the present embodiment, when the sensor failure detection unit 10 detects that the first temperature detection unit 8 has failed, heating is performed with the heating thermal power P2 and P1 before the failure for a certain period of time from the start of heating. After a certain period of time, the heating thermal power is reduced to Pa2 and Pa1 so as to perform similar thermal power control. That is, the timing for switching the set thermal power lower than the initial timing is performed after a certain period of time after the failure detection of the temperature detection means 8 by the sensor failure detection means 10, so that heating is started when a high thermal power is required, such as cooking fried food. After that, the heating thermal power at the time of start-up until the temperature of the object to be heated 1 sufficiently rises is the same as before the failure, and after the temperature of the object to be heated 1 rises, the heating thermal power is decreased to prevent an abnormally high temperature. I have to.

このように、故障していない温度検知手段９を用いて温度検知しても、複数段階の設定火力Ｐ２からＰ１をＰａ２からＰａ１へそれぞれ当初よりも低く切り替えることで、被加熱物１は異常高温になることなく故障前と同等の温度で制御でき、安全に使用することができるものである。また、本実施の形態はもとより、実施の形態３においても、設定火力を再設定するタイミングを配慮することにより、炒め物調理等、高火力を必要とする調理での故障前後の火力感の差を小さくし、故障中でも故障前と同様の使用感で安全に加熱を続けることができるものである。また、先の実施の形態と同様、温度検知手段としては、第１、第２の温度検知手段８、９の２つに限られるものではなく、それ以上であってもよいものである。   Thus, even if the temperature is detected using the temperature detecting means 9 that is not malfunctioning, the heated object 1 is heated to an abnormally high temperature by switching the setting thermal powers P2 to P1 from a plurality of stages to lower than Pa2 to Pa1, respectively. Therefore, it can be controlled at the same temperature as before the failure and can be used safely. In addition to the present embodiment, the difference in the thermal feeling before and after the failure in cooking that requires high thermal power, such as stir-fried cooking, by considering the timing for resetting the set thermal power in Embodiment 3 as well. It is possible to continue heating safely with the same feeling of use as before the failure even during a failure. Further, as in the previous embodiment, the temperature detecting means is not limited to the first and second temperature detecting means 8 and 9, and may be more than that.

（実施の形態５）
図７は、本発明の実施の形態５における誘導加熱調理器を示している。 (Embodiment 5)
FIG. 7 shows an induction heating cooker according to the fifth embodiment of the present invention.

本実施の形態においては、操作手段１４と、被加熱物１の加熱開始から予め定めた所定時間を越えると加熱を停止する切り忘れ防止タイマ１５を備え、複数の温度検知手段８、９のうち、一つの温度検知手段８が故障したことをセンサ故障検知手段１０で検知した場合には、制御手段１３は、切り忘れ防止タイマ１５の予め定めた所定時間を当初よりも短く再設定するようにしたものである。   In the present embodiment, the operating means 14 and a forget-off prevention timer 15 that stops heating when a predetermined time has elapsed from the start of heating of the article 1 to be heated are provided. When the sensor failure detection means 10 detects that one temperature detection means 8 has failed, the control means 13 resets a predetermined time for the forget-off prevention timer 15 to be shorter than the initial time. It is.

以上のように構成された加熱調理器において、切忘れ防止タイマ１５は操作手段１４から最後に入力された後の時間を計時しており、計時時間が、例えば、４５分を超えるとオン時間零、つまりスイッチング素子６ａの駆動を停止する信号を駆動手段７に出力し、被加熱物１の加熱が停止されるようになっている。   In the cooking device configured as described above, the forgetting-off prevention timer 15 measures the time after the last input from the operation means 14, and when the time exceeds 45 minutes, for example, the on-time is zero. That is, a signal for stopping the driving of the switching element 6a is output to the driving means 7, and the heating of the article 1 to be heated is stopped.

このように、故障していない温度検知手段９を用いて温度検知しても、切り忘れ防止タイマ１５の予め定めた所定時間を当初よりも短く再設定するようにしたことにより、故障前に比べて切り忘れ防止機能による加熱停止が早くなるため、被加熱物１の温度が異常に高くなることがなく、安全に切り忘れ防止を行うことができる。   Thus, even if the temperature is detected using the temperature detecting means 9 that is not malfunctioning, the preset predetermined time of the forgetting to cut off timer 15 is reset to be shorter than the original, so that compared to before the malfunction. Since the heating stop by the forgetting to cut prevention function is accelerated, the temperature of the article to be heated 1 does not become abnormally high, and forgetting to cut can be safely prevented.

なお、上記した各実施の形態において、第１の温度検知手段８が故障したことをセンサ故障検知手段１０が検知した場合、第１の温度検知手段８が故障していることを報知手段１２にて報知（音、音声、光あるいは文字、記号等）することにより、制御温度や火力低下を使用者に知らせ、違和感を無くすとともに、温度制御手段の故障である旨を認識して使用者に修理を促すことができるものである。   In each of the embodiments described above, when the sensor failure detection means 10 detects that the first temperature detection means 8 has failed, the notification means 12 indicates that the first temperature detection means 8 has failed. By informing the user (sound, voice, light or letters, symbols, etc.), the user is informed of the control temperature and thermal power drop, and the user feels that there is no sense of incongruity. Can be encouraged.

以上のように、本発明にかかる加熱調理器は、複数の温度検知手段のうち、少なくとも一つの温度検知手段が故障した場合でも、被加熱物の温度が異常高温になることなく安全に使用できるものであり、誘導加熱調理器はもとよりラジェントヒータやシーズヒータ、ハロゲンヒータ等の加熱手段を用いた各種の加熱調理器として有用である。   As described above, the cooking device according to the present invention can be used safely without any abnormally high temperature of the object to be heated even when at least one of the temperature detecting means fails. In addition to induction heating cookers, it is useful as various heating cookers using heating means such as a radiant heater, a sheathed heater, and a halogen heater.
