Description

本発明は、調理容器を載置して加熱する天板の下方に誘導加熱コイルを配置すると共に、天板と誘導加熱コイルとの間に配置した温度センサの出力等に基づいて誘導加熱コイルの火力を制御する電磁調理器に関する。   In the present invention, an induction heating coil is disposed below a top plate on which a cooking container is placed and heated, and the induction heating coil is controlled based on the output of a temperature sensor disposed between the top plate and the induction heating coil. The present invention relates to an electromagnetic cooker that controls thermal power.

一方、上記特許文献１に示される様に、天板を介して調理容器の温度を間接的に検出する場合、例えば３ＫＷ等の高出力で加熱を開始すると調理容器の温度上昇に比較して天板の温度上昇が遅くなり、フライパンに少量（例えば約１０ｇ）の油を入れて加熱を開始すると、温度センサの検出による誘導加熱コイルの火力低下が遅くなり、油が自然発火を生じるという問題がある。   On the other hand, as shown in Patent Document 1 above, when the temperature of the cooking container is indirectly detected via the top plate, when heating is started at a high output such as 3 KW, the temperature of the cooking container is compared with that of the cooking container. When the temperature rise of the plate is slow, and heating is started with a small amount (for example, about 10 g) of oil in the frying pan, the decrease in the heating power of the induction heating coil due to the detection of the temperature sensor becomes slow, and the oil causes spontaneous ignition. is there.

尚、上記少量油による自然発火の場合、発火後約１分〜１分半程度で油が燃え尽きて自然鎮火するものの、自然発火そのものが好ましくないものである。   In the case of spontaneous ignition with the above-mentioned small amount of oil, although the oil burns out and extinguishes spontaneously in about 1 minute to 1 and a half minutes after ignition, spontaneous ignition itself is not preferable.

そこで本発明は、温度センサの検出遅れによる少量油の発火を防止する事を目的とするものである。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent ignition of a small amount of oil due to a detection delay of a temperature sensor.

A temperature sensor for detecting heat, a heating power setting means for setting the heating power of the induction heating coil, and a control means for controlling the heating power of the induction heating coil based on the output of the heating power setting means and the temperature sensor, etc. After the control means starts energizing the heating coil, while the temperature detected by the temperature sensor reaches a preset temperature, the set heating power of the induction heating coil is preset regardless of the heating power set by the heating power setting means. It is constituted so as to be maintained.

本発明の請求項４の構成は、請求項３の構成において、所定温度を約６０度Ｃに設定すると共に設定火力を約２ＫＷに設定して成るものである。   According to a fourth aspect of the present invention, in the configuration of the third aspect, the predetermined temperature is set to about 60 degrees C and the set thermal power is set to about 2 kW.

本発明の請求項１に記載の構成により、加熱開始時の設定火力が予め設定した所定火力以上に設定されていた場合には、加熱開始から予め設定した所定時間、誘導加熱コイルの火力を設定火力に係わらず設定火力に維持することで、誤って設定火力を高く設定しても、自動的に火力を下げて、安全性を向上する事が出来るものである。   According to the configuration of the first aspect of the present invention, when the set thermal power at the start of heating is set to be equal to or higher than a predetermined thermal power set in advance, the thermal power of the induction heating coil is set for a predetermined time from the start of heating. By maintaining the set thermal power regardless of the thermal power, even if the set thermal power is erroneously set high, the thermal power can be automatically lowered to improve safety.

而して、誘導加熱コイル３，４を使用して加熱調理を行う場合の動作を説明すると、天板２の誘導加熱コイル３，４の上方に鍋等の調理容器２６を載せた後（図４参照）、電源スイッチ９をオン操作し、次いで操作パネル６の摘み１１をプュシュ操作して引き出して回転操作、又は操作部１３の火力キー１６・・にて火力を設定操作することで、これらの操作を主制御回路３４並びに副制御回路６０にて検出して誘導加熱コイル４への通電を開始して調理を開始する。   Thus, the operation when cooking using the induction heating coils 3 and 4 will be described. After the cooking container 26 such as a pan is placed above the induction heating coils 3 and 4 of the top plate 2 (FIG. 4), the power switch 9 is turned on, and then the knob 11 of the operation panel 6 is pushed and pulled out to rotate, or the heating power is set with the heating key 16. This operation is detected by the main control circuit 34 and the sub-control circuit 60, energization of the induction heating coil 4 is started, and cooking is started.

一方、上記主制御回路３４並びに副制御回路６０は、上記操作パネル６又は操作部１３で設定された誘導加熱コイル３，４の設定火力が、予め設定した所定火力（例えば２ＫＷ）以上に設定された場合には、図５にて示す様に、加熱開始から予め設定した所定時間Ｔ１（例えば約９０秒）の間は、上記設定火力に関係なく、予め設定した所定火力（例えば約２ＫＷ）に設定する様に構成している。   On the other hand, in the main control circuit 34 and the sub control circuit 60, the set heating power of the induction heating coils 3 and 4 set by the operation panel 6 or the operation unit 13 is set to a predetermined heating power (for example, 2 kW) or more. In this case, as shown in FIG. 5, during a predetermined time T1 (for example, about 90 seconds) preset from the start of heating, the predetermined heat power (for example, about 2 kW) is set regardless of the set heat power. It is configured to set.

これらの構成により、誤って調理容器２６内に少量油を入れて調理を開始しながら、火力を所定火力よりも高い最大火力等に設定して調理を開始しても、調理開始から所定時間の間は強制的に火力を所定火力に維持することで、誤操作による自然発火を防止する事が出来るものである。   With these configurations, even if a small amount of oil is accidentally put into the cooking container 26 and cooking is started, even if the cooking is started by setting the heating power to a maximum heating power higher than the prescribed heating power, etc. In the meantime, by spontaneously maintaining the heating power at a predetermined heating power, spontaneous ignition due to erroneous operation can be prevented.

又、調理容器２６に適正量の被調理物が投入された場合でも、９０秒間のみ火力を所定火力に制限することで、調理時間を大幅に延長することなく、使い勝手への影響を最小限に留めることが出来るものである。   Even when an appropriate amount of food is put into the cooking container 26, the heating power is limited to the predetermined heating power only for 90 seconds, so that the cooking time is not significantly extended and the influence on the usability is minimized. It can be fastened.

図６は本発明の他の実施例を示すもので、上記と同様に天板２の上方に被調理物を入れた調理容器２６を載せ、操作パネル６又は操作部１３より火力を設定して調理を開始すると、上記主制御回路３４並びに副制御回路６０にて、温度センサ６２の出力から調理容器２６の温度を検出し、かつこの検出温度が予め設定した所定温度（例えば約６０度Ｃ）に到達する間Ｔ２は、上記設定火力に関係なく、予め設定した所定火力（例えば約２ＫＷ）に設定する様に構成している。   FIG. 6 shows another embodiment of the present invention. In the same manner as described above, a cooking container 26 in which an object to be cooked is placed above the top plate 2 and the heating power is set from the operation panel 6 or the operation unit 13. When cooking is started, the main control circuit 34 and the sub control circuit 60 detect the temperature of the cooking container 26 from the output of the temperature sensor 62, and the detected temperature is set to a predetermined temperature (for example, about 60 degrees C). T2 is configured to be set to a predetermined thermal power set in advance (for example, about 2 kW) regardless of the set thermal power.

これらの構成により、調理容器２６の底面が反っていたり、誘導加熱に適さない材質の調理容器２６が使用されている等の何らかの原因により、温度センサが適切に調理容器２６の温度を検出できない場合でも、少量油の加熱による自然発火を確実に防止する事が出来るものである。   When the temperature sensor cannot properly detect the temperature of the cooking container 26 due to some reason such as the bottom surface of the cooking container 26 being warped or using the cooking container 26 made of a material that is not suitable for induction heating. However, spontaneous ignition due to heating of a small amount of oil can be reliably prevented.

尚、上記実施例では所定温度を約６０度Ｃに設定し、かつ所定火力を約２ＫＷに設定することで、少量油による加熱時の調理容器２６温度の検出遅れによる自然発火を防止しているが、これに限定されることなく、天板２の材質や板厚、温度センサ６２の感度等に応じて所定温度や所定火力を設定すれば良い。   In the above embodiment, the predetermined temperature is set to about 60 degrees C and the predetermined heating power is set to about 2 kW to prevent spontaneous ignition due to detection delay of the cooking vessel 26 temperature when heated with a small amount of oil. However, the present invention is not limited to this, and the predetermined temperature and the predetermined heating power may be set according to the material and thickness of the top plate 2, the sensitivity of the temperature sensor 62, and the like.

又、上記操作パネル６又は操作部１３で設定された火力は、天板２に配置した液晶表示器２２に表示されるが、上記加熱開始の所定時間は、例えば所定火力を示す数字表示を点滅させ、所定時間経過後に設定された火力を表示させる等により、入力された設定火力に対して火力を下げている旨を表示しても良いし、設定火力のみ表示させても良い。   Further, the heating power set by the operation panel 6 or the operation unit 13 is displayed on the liquid crystal display 22 arranged on the top plate 2. The predetermined time for starting the heating blinks, for example, a numerical display indicating the predetermined heating power. It is possible to display that the set thermal power is lowered with respect to the input set thermal power, for example, by displaying the thermal power set after a predetermined time has elapsed, or to display only the set thermal power.
