Description

【０００１】
【発明の属する技術分野】
本発明は、加熱時に油の入った鍋等の過昇防止機能を備えた加熱調理器に関する。
【０００２】
【従来の技術】
鍋等を加熱する加熱調理器においては、油の入った鍋を加熱し続けると油の温度が上昇し、発火温度まで達する危険があるため、温度検知手段により検知した鍋等の温度が、所定の温度を超えたら加熱停止するようにしきい値温度を設けているのが一般的である。また、加熱出力を複数段階有する加熱調理器では、各加熱出力に応じての制御温度（しきい値）を設け、温度検知手段により検知した温度がその制御温度を超えた場合に現在の加熱出力を小さくし、検知温度が制御温度を下回った場合には、現在の加熱出力を大きくするよう制御している。以下図を用いて説明する。
【０００３】
図６は従来の加熱調理器の構成ブロック図である。図６において、１は油や調理物を入れて調理する鍋、２は鍋１を載置するトッププレート、３はトッププレート２の裏面に配置されトッププレート２を介して鍋１の温度を検知する温度検知手段、４はインバータ回路と加熱コイルで形成されている加熱手段、５は加熱手段４の出力を６段階（０Ｗ、３３０Ｗ、５００Ｗ、９００Ｗ、１４５０Ｗ、２０００Ｗ）に制御する加熱制御手段、６は加熱手段の出力に応じて設けられたしきい値となる制御温度（制御温度記憶手段（図示せず）に記憶されている）、７は温度制御手段であり、温度検知手段３で検知した温度と加熱手段４の出力に応じて設定された制御温度６の値とを比較し、温度検知手段３で検知した温度が制御温度６の値を超えるあるいは下回った場合に、加熱制御手段５に加熱手段の出力を変更するように信号を出力する。
【０００４】
以上のように構成された加熱調理器について図７をもちいてその動作を説明する。図７は鍋１に油を入れて加熱した場合の図であり、上段の図が温度検知手段３（以下センサと呼ぶ）で検知した温度の推移およびその時の実際の油温であり、下段が加熱手段４の出力を図示したものである。
【０００５】
まず、加熱手段４の出力は２０００Ｗで鍋１を加熱している。この時温度制御手段７は、加熱手段４の出力に対応する制御温度（この場合は１８５℃）よりもセンサで検知した温度（以下センサ温度と呼ぶ）が高いか低いかを判断する。そして、加熱開始からｔ７１後、センサ温度が１８５℃を超えたので、温度制御手段７は加熱制御手段５に対して、加熱手段４の出力を下げるよう信号を出力する。加熱制御手段５は温度制御手段７の信号を受けて、加熱手段４の出力が１段階小さい出力（１４５０Ｗ）になるように加熱手段４を制御する。以下同様の制御を繰り返し、加熱手段４の出力が３３０Ｗの時にセンサ温度が２３０℃を超えると（ｔ７５）、加熱制御手段５は加熱手段４の出力を停止すなわち出力を０Ｗにする。また、温度制御手段７は、加熱手段４の出力が０Ｗの時センサ温度が２３０℃を下回ったら（ｔ７６）、加熱制御手段５に対して、加熱手段４の出力を上げるように信号を出力する。加熱制御手段５は温度制御手段７の信号を受けて、加熱手段４の出力が１段階大きい出力（３３０Ｗ）になるように加熱手段４を制御する。
【０００６】
【発明が解決しようとする課題】
一般に鍋に入った油量により、センサ温度と油温の関係は異なるため、油量が少ない場合でも油温が発火温度に達するのを抑えるためには、各加熱出力に応じた制御温度６を低い温度に設定しておく必要がある。しかし制御温度６を低く設定しすぎると、炒め物調理のときなど加熱出力が下がりやすく火力不足となり、調理性能が低下してしまう。
【０００７】
本発明は上記従来の課題を解決するもので、鍋内の油量が少ない場合にもピーク温度を低下させるとともに、炒め物調理等での火力不足になりにくくする加熱調理器を提供することを目的としている。
【０００８】
【課題を解決するための手段】
上記従来の課題を解決するために、本発明は、温度制御手段の出力により前記制御温度の値を変更する制御温度変更手段を備えた加熱調理器とするものである。
【０００９】
【発明の実施の形態】
請求項１記載の発明は、鍋等を加熱する加熱手段と、前記加熱手段の出力を複数段階に制御する加熱制御手段と、鍋等の温度を検知する温度検知手段と、前記加熱手段の出力に応じた複数の制御温度と、前記温度検知手段で検知した温度と前記加熱手段の出力に応じた制御温度により、前記加熱手段の出力を変更するよう前記加熱制御手段に信号を出力する温度制御手段と、前記温度制御手段の出力により前記制御温度の値を変更する制御温度変更手段を備え、温度検知手段で検知した温度が第一の制御温度を超え加熱手段の出力が小さくなったとき、前記第一の制御温度より低い第二の制御温度の値を所定温度上げるようにするものであり、前記温度検知手段により検知される温度が上昇から下降に変わった場合に、温度が上昇しているときより、高い温度で前記加熱手段の出力を大きくすることができるので、鍋等を加熱中に調理物である負荷が投入された場合に、鍋の温度低下が比較的小さい段階で前記加熱手段の出力を大きくし、炒め物調理等での火力不足を防ぎ調理性能を確保することができる。
【００１０】
請求項２記載の発明は、特に、請求項１に記載の制御温度変更手段は、温度検知手段で検知した温度が第四の制御温度を下回り加熱手段の出力が大きくなったとき、前記第三の制御温度より高い第四の制御温度の値を所定温度下げるようにするものであり、前記温度検知手段により検知される温度が下降から上昇に変わった場合に低い温度で前記加熱手段の出力を小さくすることができるので、油の入った鍋等を加熱中に調理物などの負荷が投入されずに放置された場合や、負荷が軽く油の温度低下がほとんどない場合などの油温の上昇を抑えることができる。
【００１１】
請求項３記載の発明は、特に、請求項２に記載の制御温度変更手段は、予め決められた制御温度の最高温度に対して、制御温度を下げる変更を行わないようにするもので、特に制御温度の最高温度を超えた場合に前記加熱手段の出力を停止するような調理器の場合で、低い温度で加熱停止してしまって十分な火力が得られず調理性能が低下するといったことを防ぐことができる。
【００１２】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。
【００１３】
（実施例１）
図１は本発明の第１の実施例における加熱調理器の回路ブロック図を示したものである。なお、本実施例において、前述の従来例と同一の構成には同じ符号を付し、その説明は省略する。
【００１４】
本実施例の特徴的構成は、制御温度変更手段８を新たに設け、温度制御手段７が加熱制御手段５に信号を出力すると制御温度記憶手段（図示せず）に記憶された特定の制御温度６の値を変更するようにしたものである。以下制御温度変更手段８の動作について図２、３を用いて説明する。
【００１５】
図２は鍋１に油を入れて加熱した場合の図、図３は炒め物調理をした場合の図である。図２において上段が温度検知手段３（以下センサと呼ぶ）で検知した温度の推移およびその時の実際の油温であり、下段が加熱手段４の出力を図示している。
【００１６】
まず、加熱手段４の出力は２０００Ｗで鍋１を加熱している。この時温度制御手段７は、加熱手段４の出力に対応する制御温度（この場合は１８５℃）よりもセンサで検知した温度（以下センサ温度）が高いか低いかを判断する。そして、加熱開始からｔ２１後、センサ温度が１８５℃を超えたので、温度制御手段７は加熱制御手段５に対して、加熱手段４の出力を下げるよう信号を出力する。加熱制御手段５は温度制御手段７の信号を受けて、加熱手段４の出力が１段階小さい出力（１４５０Ｗ）になるように加熱手段４を制御する。更に加熱を続け、ｔ２２後センサ温度が２０３℃を超えると、温度制御手段７は加熱制御手段５に対して、加熱手段４の出力を下げるよう信号を出力する。加熱制御手段５は温度制御手段７の信号を受けて、加熱手段４の出力が１段階小さい出力（９００Ｗ）になるように加熱手段４を制御する。そして、制御温度変更手段８は加熱手段４の出力が変更される制御温度６（本実施例では２０３℃）よりも低い制御温度（本実施例では１８５℃）を５℃上げて１９０℃に変更する。以下その動作を繰り返し行っていく。
【００１７】
一般に鍋に油を入れて加熱し従来例のような加熱動作を行った場合、油温は最初に加熱停止した直後が最も高くなり、その後加熱を再開し次に加熱停止したときの温度は初回のピーク温度よりも低くなる。また、油量が少なかったり、本実施例のように間接的に温度を検知している場合などは、センサ温度と実際の油温の差が大きく開く場合が多い。
【００１８】
本実施例では、加熱開始から初回加熱停止した後、センサ温度が低下し再度加熱手段４にて加熱が再開するタイミングが早くなり、２回目のピーク温度が高くなる。しかし、炒め物調理など調理物が投入された場合に従来よりも早いタイミングで加熱手段４の出力を１段階大きくすることができる。なお、本実施例のように一度制御温度変更手段８にて値を大きくした制御温度は、再度大きくすることを禁止しておけば、制御温度が逆転現象を起こしたり、値が高く成りすぎ危険な状態になると言ったことを防ぐことができる。
【００１９】
なお、本実施例の各動作において、加熱手段は誘導加熱としたが、ガスやヒータによる加熱においても、負荷鍋の温度を同様の検知方式で検知する場合には同様の作用と効果を得ることができるものである。
【００２０】
（実施例２）
以下第２の実施例について図を用いて説明する。本実施例において構成は第１の実施例と同じであるため省略し、制御温度変更手段８の動作の異なる部分について説明する。
【００２１】
図４、５は本実施例での制御温度変更手段８の動作とセンサ温度の推移を示した図である。図４で示すようにセンサ温度が制御温度６の値よりも下回り、温度制御手段７が加熱制御手段５に加熱手段４の出力を大きくするように信号を出力した場合に、制御温度変更手段８により制御温度６の値を低くするように変更すれば、２回目以降のピークを小さくすることができる。具体的には、図４において加熱手段４にて５００Ｗで加熱しているとき（ｔ４７からｔ４８の間）、センサ温度が２１８℃を下回ると（ｔ４８）、温度制御手段７より加熱制御手段５に対して、加熱手段４の出力を上げるように信号を出力する。加熱制御手段５は温度制御手段７の信号を受けて、加熱手段４の出力が１段階大きい出力（９００Ｗ）になるように加熱手段４を制御する。同時に制御温度変更手段８はその時の制御温度（２１８℃）より高い制御温度（２２５℃）を３℃下げて２２２℃に変更する。また、制御温度の最高値（本実施例では２３０℃）に対しては、変更しないようにすれば、加熱停止しやすくなることはない。
【００２２】
また、図５のようにセンサ温度が上昇中の時は制御温度を高くし、センサ温度が下降中は一端変更して高くなった、制御温度を元に戻す（低くする）ようにすれば、油加熱において従来と同等の性能を確保しつつ、炒め物などの調理性能を改善することができる。更に、本実施例における制御温度は従来例と同じ値としたが、制御温度の初期値を従来例よりも低い温度で設定しておけば、油加熱にたいせて更に、ピーク温度を低く抑えることが可能である。
【００２３】
なお、本実施例の各動作において、加熱手段は誘導加熱としたが、ガスやヒータによる加熱においても、負荷鍋の温度を同様の検知方式で検知する場合には同様の作用と効果を得ることができるものである。
【００２４】
【発明の効果】
以上のように本発明によれば、加熱手段の出力に応じて設定される制御温度を温度制御手段の出力により変更するものであり、前記制御温度の値が常に一定ではなく、温度検知手段で検知した温度により変更されるので、あらかじめ各制御温度は低い値にでき油加熱時の過昇防止を行うとともに、油加熱と異なった炒め物調理等のときの調理性能を確保することができる加熱調理器を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cooking device having a function of preventing overheating of a pot or the like containing oil during heating.
[0002]
[Prior art]
In a cooking device that heats a pot or the like, if the pot containing oil is continuously heated, the temperature of the oil rises and there is a risk of reaching the ignition temperature. In general, a threshold temperature is set so that heating is stopped when the temperature exceeds the temperature. In a heating cooker having a plurality of heating outputs, a control temperature (threshold) corresponding to each heating output is provided, and when the temperature detected by the temperature detecting means exceeds the control temperature, the current heating output is set. Is reduced, and when the detected temperature falls below the control temperature, the current heating output is controlled to be increased. This will be described below with reference to the drawings.

In FIG. 6, reference numeral 1 denotes a pot for cooking with oil or food, 2 a top plate on which the pot 1 is placed, and 3 a temperature sensor disposed on the back of the top plate 2 to detect the temperature of the pot 1 via the top plate 2. A heating control means for controlling the output of the heating means 4 in six stages (0 W, 330 W, 500 W, 900 W, 1450 W, 2000 W); Reference numeral 6 denotes a control temperature (stored in a control temperature storage unit (not shown)) serving as a threshold provided according to the output of the heating unit. Reference numeral 7 denotes a temperature control unit, which is detected by the temperature detection unit 3. The detected temperature is compared with the value of the control temperature 6 set in accordance with the output of the heating means 4, and when the temperature detected by the temperature detection means 3 exceeds or falls below the value of the control temperature 6, the heating control means 5 Heating hands Outputs a signal to change the output of.
[0004]
The operation of the heating cooker configured as described above will be described with reference to FIG. FIG. 7 is a diagram in a case where oil is put into the pan 1 and heated. The upper diagram shows the transition of the temperature detected by the temperature detecting means 3 (hereinafter referred to as a sensor) and the actual oil temperature at that time. 3 shows the output of the heating means 4.
[0005]
First, the output of the heating means 4 heats the pan 1 at 2000W. At this time, the temperature control means 7 determines whether the temperature detected by the sensor (hereinafter referred to as the sensor temperature) is higher or lower than the control temperature (185 ° C. in this case) corresponding to the output of the heating means 4. Then, after t71 from the start of heating, since the sensor temperature has exceeded 185 ° C., the temperature control means 7 outputs a signal to the heating control means 5 so as to reduce the output of the heating means 4. The heating control means 5 receives the signal from the temperature control means 7 and controls the heating means 4 so that the output of the heating means 4 becomes one step smaller output (1450 W). Hereinafter, the same control is repeated. When the sensor temperature exceeds 230 ° C. when the output of the heating unit 4 is 330 W (t75), the heating control unit 5 stops the output of the heating unit 4, that is, sets the output to 0 W. When the output of the heating means 4 is 0 W and the sensor temperature falls below 230 ° C. (t76), the temperature control means 7 outputs a signal to the heating control means 5 so as to increase the output of the heating means 4. . The heating control means 5 receives the signal of the temperature control means 7 and controls the heating means 4 so that the output of the heating means 4 becomes one step higher output (330 W).
[0006]
[Problems to be solved by the invention]
In general, since the relationship between the sensor temperature and the oil temperature differs depending on the amount of oil put into the pan, even if the amount of oil is small, to control the oil temperature from reaching the ignition temperature, the control temperature 6 according to each heating output must be controlled. It is necessary to set a low temperature. However, if the control temperature 6 is set too low, the heating output tends to decrease, such as when cooking a stir-fry, resulting in insufficient heating power and a decrease in cooking performance.
[0007]
The present invention solves the above-mentioned conventional problems, and provides a heating cooker that reduces the peak temperature even when the amount of oil in a pan is small, and that is less likely to be short of thermal power in stir-fry cooking or the like. The purpose is.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned conventional problems, the present invention provides a heating cooker including a control temperature changing means for changing a value of the control temperature by an output of a temperature control means.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
The invention according to claim 1 is a heating means for heating a pot or the like, a heating control means for controlling the output of the heating means in a plurality of stages, a temperature detecting means for detecting a temperature of the pot or the like, and an output of the heating means. Temperature control that outputs a signal to the heating control means to change the output of the heating means, based on a plurality of control temperatures according to the temperature, and a control temperature corresponding to the temperature detected by the temperature detection means and the output of the heating means. Means, comprising a control temperature changing means for changing the value of the control temperature by the output of the temperature control means , when the temperature detected by the temperature detection means exceeds the first control temperature and the output of the heating means is reduced, It is to increase the value of the second control temperature lower than the first control temperature by a predetermined temperature, and when the temperature detected by the temperature detecting means changes from rising to falling, the temperature rises When you are Since the output of the heating means can be increased at a higher temperature, when a load that is a cooking product is supplied while the pot or the like is being heated, the heating means is turned off at a stage where the temperature drop of the pan is relatively small. It is possible to increase the output and prevent shortage of heat in stir-fry cooking or the like and secure cooking performance.
[0010]
According to a second aspect of the present invention, when the temperature detected by the temperature detecting unit falls below the fourth control temperature and the output of the heating unit becomes large, the control temperature changing unit according to the first aspect of the present invention provides the control temperature changing unit. The temperature of the fourth control temperature higher than the control temperature is to be lowered by a predetermined temperature, the output of the heating means at a lower temperature when the temperature detected by the temperature detecting means has changed from falling to rising. Oil temperature rises when a pot containing oil is left unheated and no load is applied during heating, or when the load is light and there is almost no drop in oil temperature. Can be suppressed.
[0011]
According to a third aspect of the present invention, in particular, the control temperature changing means according to the second aspect prevents a change in lowering the control temperature from a predetermined maximum control temperature. In the case of a cooker in which the output of the heating means is stopped when the maximum temperature of the control temperature is exceeded, such a situation that heating is stopped at a low temperature, sufficient heating power cannot be obtained, and cooking performance is reduced. Can be prevented.
[0012]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0013]
(Example 1)
FIG. 1 is a circuit block diagram of a heating cooker according to a first embodiment of the present invention. In this embodiment, the same components as those of the above-described conventional example are denoted by the same reference numerals, and the description thereof will be omitted.
[0014]
A characteristic configuration of the present embodiment is that a control temperature changing means 8 is newly provided, and when the temperature control means 7 outputs a signal to the heating control means 5, a specific control temperature stored in the control temperature storage means (not shown) is stored. 6 is changed. The operation of the control temperature changing means 8 will be described below with reference to FIGS.
[0015]
FIG. 2 is a diagram in a case where oil is put into the pot 1 and heated, and FIG. 3 is a diagram in a case where a stir-fry is cooked. In FIG. 2, the upper part shows the transition of the temperature detected by the temperature detecting means 3 (hereinafter referred to as a sensor) and the actual oil temperature at that time, and the lower part shows the output of the heating means 4.
[0016]
First, the output of the heating means 4 heats the pan 1 at 2000W. At this time, the temperature controller 7 determines whether the temperature detected by the sensor (hereinafter, sensor temperature) is higher or lower than the control temperature (185 ° C. in this case) corresponding to the output of the heater 4. Then, after t21 from the start of heating, since the sensor temperature has exceeded 185 ° C., the temperature control means 7 outputs a signal to the heating control means 5 so as to reduce the output of the heating means 4. The heating control means 5 receives the signal from the temperature control means 7 and controls the heating means 4 so that the output of the heating means 4 becomes one step smaller output (1450 W). When the sensor temperature exceeds 203 ° C. after t22, the temperature control unit 7 outputs a signal to the heating control unit 5 to reduce the output of the heating unit 4. The heating control means 5 receives the signal of the temperature control means 7 and controls the heating means 4 so that the output of the heating means 4 becomes one step smaller output (900 W). Then, the control temperature changing means 8 increases the control temperature (185 ° C. in this embodiment) lower than the control temperature 6 (203 ° C. in this embodiment) at which the output of the heating means 4 is changed to 190 ° C. by 5 ° C. I do. Hereinafter, the operation is repeatedly performed.
[0017]
In general, when oil is put into a pan and heated, and the heating operation is performed as in the conventional example, the oil temperature becomes highest immediately after the first heating is stopped, and then the heating is resumed, and then the temperature when the heating is stopped is the first time. Lower than the peak temperature. Further, when the amount of oil is small or when the temperature is indirectly detected as in the present embodiment, the difference between the sensor temperature and the actual oil temperature often greatly increases.
[0018]
In this embodiment, after the first heating is stopped from the start of heating, the temperature of the sensor decreases, the timing at which heating is restarted again by the heating means 4 is advanced, and the second peak temperature is increased. However, when foods such as stir-fry cooking are introduced, the output of the heating means 4 can be increased by one step at an earlier timing than before. If the control temperature once increased by the control temperature changing means 8 as in the present embodiment is prohibited from being increased again, the control temperature may cause a reversal phenomenon or the value may become too high. Can be prevented from being said to be in a state.
[0019]
In each operation of the present embodiment, the heating means is induction heating. However, in the case of heating by gas or a heater, the same operation and effect can be obtained when the temperature of the load pan is detected by the same detection method. Can be done.
[0020]
(Example 2)
Hereinafter, a second embodiment will be described with reference to the drawings. In the present embodiment, the configuration is the same as that of the first embodiment, so that the description thereof will be omitted, and only the operation of the control temperature changing means 8 will be described.
[0021]
4 and 5 are diagrams showing the operation of the control temperature changing means 8 and the transition of the sensor temperature in this embodiment. As shown in FIG. 4, when the sensor temperature is lower than the value of the control temperature 6 and the temperature control means 7 outputs a signal to the heating control means 5 to increase the output of the heating means 4, the control temperature changing means 8 Therefore, if the value of the control temperature 6 is changed to be lower, the peaks after the second time can be made smaller. Specifically, in FIG. 4, when the heating unit 4 is heating at 500 W (between t47 and t48), and the sensor temperature falls below 218 ° C. (t48), the temperature control unit 7 sends the heating control unit 5 On the other hand, a signal is output so as to increase the output of the heating means 4. The heating control means 5 receives the signal from the temperature control means 7 and controls the heating means 4 so that the output of the heating means 4 becomes an output (900 W) which is higher by one step. At the same time, the control temperature changing means 8 lowers the control temperature (225 ° C.) higher than the control temperature (218 ° C.) at that time by 3 ° C. and changes it to 222 ° C. In addition, if the maximum value of the control temperature (230 ° C. in this embodiment) is not changed, the heating is not easily stopped.
[0022]
Also, as shown in FIG. 5, when the sensor temperature is increasing, the control temperature is increased, and when the sensor temperature is decreasing, the control temperature is changed once and then increased, and the control temperature is returned (reduced). It is possible to improve the cooking performance of a stir-fry or the like while securing the same performance in oil heating as before. Further, the control temperature in the present embodiment is set to the same value as that of the conventional example, but if the initial value of the control temperature is set at a lower temperature than the conventional example, the peak temperature is further reduced for oil heating. It is possible.
[0023]
In each operation of the present embodiment, the heating means is induction heating. However, in the case of heating by gas or a heater, the same operation and effect can be obtained when the temperature of the load pan is detected by the same detection method. Can be done.
[0024]
【The invention's effect】
