しかしながら、前記従来の構成では、機器の使用環境や使用者の体の大小、体脂肪率等の人体電気特性が多様であるにもかかわらず、タッチスイッチの検知レベルは一定であり、機器のお手入れ時等に意図せずスイッチ検知してしまったり、検知レベルが使用実態に対して鈍いため操作性が悪いという課題を有していた。   However, in the above-described conventional configuration, the detection level of the touch switch is constant regardless of the use environment of the device, the size of the user's body, and the human body electrical characteristics such as body fat percentage. There are problems such as unintentional switch detection during maintenance, and poor operability because the detection level is dull relative to the actual usage.

本発明は、タッチスイッチの検知レベルをタッチスイッチ調整モードで自動的に切り替えることで、実際の機器の使用環境や使用者の体の大小、体脂肪率等に対して最適なスイッチ感度を実現できる使い勝手のよい加熱調理器を提供することを目的とする。   In the present invention, the switch switch detection level is automatically switched in the touch switch adjustment mode, so that the optimum switch sensitivity can be realized with respect to the actual use environment of the device, the size of the user's body, the body fat percentage, etc. An object is to provide an easy-to-use cooking device.

前記従来の課題を解決するために、本発明の加熱調理器は、外郭を構成する本体と、本体の上面に設けた天板と、天板上に載置された被加熱物を高周波電流により誘導加熱する誘導加熱手段と、被加熱物の種別を判別する被加熱物判別手段と、天板と略同一面に設けられ誘導加熱手段を制御する静電容量式のタッチスイッチと、前記タッチスイッチに人が触れていない時の基準電圧と、人が触れたときの検知電圧の差分電圧が、所定時間以上の間、所定電圧レベルより大きくなった時、スイッチ入力されたと認識する制御手段と、差分電圧を記憶する記憶手段を備え、使用者が容易に設定可能なタッチスイッチ調整モードにおいて、前記記憶手段の差分電圧を元に、前記所定電圧レベルを自動的に設定することを可能とすることで、使用環境と使用者にとって最適なスイッチ感度が手間無く設定でき、意図しないスイッチ受付防止と操作性を両立させることができ使い勝手がよい。   In order to solve the above-described conventional problems, a heating cooker according to the present invention includes a main body constituting an outer shell, a top plate provided on an upper surface of the main body, and an object to be heated placed on the top plate by a high-frequency current. Induction heating means for induction heating, heated object determination means for determining the type of the object to be heated, a capacitive touch switch provided on substantially the same surface as the top plate for controlling the induction heating means, and the touch switch A control means for recognizing that a switch is input when a difference voltage between a reference voltage when a person is not touching and a detection voltage when a person is touched is greater than a predetermined voltage level for a predetermined time or more; A storage means for storing a differential voltage is provided, and in the touch switch adjustment mode that can be easily set by a user, the predetermined voltage level can be automatically set based on the differential voltage of the storage means. In the usage environment Ideal switch sensitivity for the user can be set without trouble, it is convenient can be made compatible with the operation of unintended switch accepted prevented.

本発明の加熱調理器は、タッチスイッチの検知レベルをタッチスイッチ調整モードで自動的に切り替えることで、天面上に操作スイッチを配した機器の使い勝手を向上することができる。   The cooking device of the present invention can improve the usability of a device provided with an operation switch on the top surface by automatically switching the detection level of the touch switch in the touch switch adjustment mode.

第1の発明は、前記従来の課題を解決するために、本発明の加熱調理器は、外郭を構成する本体と、前記本体の上面に設けた天板と、前記天板上に載置された被加熱物を高周波電流により誘導加熱する誘導加熱手段と、被加熱物の種別を判別する被加熱物判別手段と、前記天板と略同一面に設けられ前記誘導加熱手段を制御する静電容量式のタッチスイッチと、前記タッチスイッチに人が触れていない時の基準電圧と、人が触れたときの検知電圧の差分電圧が、所定時間以上の間、所定電圧レベルより大きくなった時、スイッチ入力されたと認識する制御手段と、前記差分電圧を記憶する記憶手段を備え、使用者が容易に設定可能なタッチスイッチ調整モードにおいて、前記記憶手段の差分電圧を元に、前記所定電圧レベルを自動的に設定することを可能とすることで使用環境と使用者にとって最適なスイッチ感度が手間無く設定でき、意図しないスイッチ受付防止と操作性を両立させることができ使い勝手がよい。   According to a first aspect of the present invention, in order to solve the conventional problem, a heating cooker according to the present invention is mounted on a main body constituting an outer shell, a top plate provided on an upper surface of the main body, and the top plate. Induction heating means for induction heating the heated object by high-frequency current, heated object determination means for determining the type of the heated object, and electrostatic that is provided on substantially the same plane as the top plate and controls the induction heating means. When the differential voltage between the capacitive touch switch, the reference voltage when the person is not touching the touch switch, and the detected voltage when the person touches is greater than a predetermined voltage level for a predetermined time or more, Control means for recognizing that a switch has been input and storage means for storing the differential voltage. In a touch switch adjustment mode that can be easily set by a user, the predetermined voltage level is set based on the differential voltage of the storage means. Set automatically It can set optimum switch sensitivity effort without for the use environment with the user by enabling, good usability can be made compatible with the operation of unintended switch accepted prevented.

前記差分電圧は、スイッチを操作する使用者の人体内部抵抗や人体静電容量また、機器の設置状況、機器の周辺設置環境によっても変動し、また、人体以外の調理物や水がタッチスイッチ回りに付着することによっても変動する。使用環境においては、例えばテレビやラジオの放送局に近い住居等では、高周波電界ノイズ等のレベルが比較的高く、機器への直接飛び込む高周波エネルギーや人体を介して飛び込む高周波エネルギーによって、検知レベルは相対的に小さくなる。また、使用者の身体的特質に関しては、電気的人体等価モデルにおいて、体の大きい程その静電容量成分が大きく、スイッチ検知レベルは大きくなる。また、人の体の水分、体脂肪率が大きい程その抵抗成分が小さく、スイッチ検知レベルは大きくなる。このように、使用環境や使用者の特質によってタッチスイッチの検知レベルは変動するが、本発明は、検知所定電圧を実際の人が触ったときの検知レベルに元づいて自動的に設定することが可能であるため、使用者の人体の個別差、機器の設置環境の差異による差分電圧の違いを補間でき、個別に最適な検知性能を実現できるため使い勝手がよい。また、検知所定電圧の設定調整で、調理中の水、調理物の飛び散りによるスイッチ誤検知防止も、操作性とのバランスの中で設定することができ使い勝手がよい。   The differential voltage varies depending on the internal resistance and capacitance of the user who operates the switch, the installation status of the device, and the surrounding installation environment of the device. It also fluctuates by adhering to. In a usage environment, for example, in a residence near a television or radio broadcasting station, the level of high-frequency electric field noise is relatively high, and the detection level is relatively high due to the high-frequency energy that jumps directly into the equipment or the high-frequency energy that jumps through the human body. Become smaller. As for the physical characteristics of the user, in the electrical human body equivalent model, the larger the body, the larger the capacitance component and the greater the switch detection level. Also, the greater the moisture and body fat percentage of the human body, the smaller the resistance component and the higher the switch detection level. Thus, although the detection level of the touch switch varies depending on the use environment and the user's characteristics, the present invention automatically sets the predetermined detection voltage based on the detection level when the actual person touches it. Therefore, it is possible to interpolate the difference in the difference voltage due to the individual difference of the user's human body and the difference in the installation environment of the device, and the optimum detection performance can be realized individually, which is convenient. In addition, by setting and adjusting the detection predetermined voltage, prevention of erroneous switch detection due to splashing of water during cooking or cooking can be set in a balance with operability, which is convenient.

また、特に本発明にある様に誘導加熱を有した加熱調理器においては、誘導加熱時の際に発生する磁力線の影響でスイッチ検知の電器信号が変化する可能性があり、前述の影響を検知電圧を設定変更することによって回避し、使い勝手向上することができる。   In addition, particularly in a cooking device having induction heating as in the present invention, the electrical signal of the switch detection may change due to the influence of the magnetic field lines generated during induction heating, and the aforementioned influence is detected. By changing the voltage setting, this can be avoided and the usability can be improved.

また、さらに加熱部と同一面上にスイッチが配置された本発明の場合、調理物や調理機材をスイッチ部に置いてしまったり、接触させてしまったりする可能性は高く、検知電圧を切替調整できる利便性は特に高い。   In addition, in the case of the present invention in which the switch is arranged on the same surface as the heating unit, there is a high possibility that the food or cooking equipment will be placed on or contacted with the switch unit, and the detection voltage is switched and adjusted. The convenience that can be done is particularly high.

第2の発明は、タッチスイッチ調整モードにおける、記憶手段の差分電圧と所定電圧レベルの設定比率を切り替える切り替え手段を具備することで、使用者が使用状況に応じて自在にスイッチを効きやすくしたり、意図せずスイッチを触ったときに反応しにくくしたり等、スイッチ検知性能を選択でき使い勝手がよい。   The second invention includes a switching means for switching the setting ratio between the differential voltage of the storage means and the predetermined voltage level in the touch switch adjustment mode, so that the user can easily activate the switch according to the use situation. The switch detection performance can be selected, such as making it difficult to react when the switch is touched unintentionally.

第3の発明は、機器に搭載されたスイッチの所定組み合わせ操作でタッチスイッチ調整モードへの移行が可能とすることで、通常使用時に意図せず設定が変更となることがなく使い勝手がよい。また、モード移行用の専用スイッチを具備しなくてもよいため安価な構成となる。   According to the third aspect of the present invention, it is possible to shift to the touch switch adjustment mode by a predetermined combination operation of the switches mounted on the device, so that the setting is not changed unintentionally during normal use and the usability is good. Further, since it is not necessary to provide a dedicated switch for mode transition, the configuration is inexpensive.

第4の発明は、タッチスイッチ調整モードへの移行時もしくは、タッチスイッチ調整モードで設定が完了した際、そのことを報知することで、確実に設定が完了したことを使用者に知らしめることができる。   According to a fourth aspect of the present invention, when the transition to the touch switch adjustment mode is performed or when the setting is completed in the touch switch adjustment mode, the fact is notified so that the user can be surely notified that the setting has been completed. it can.

第5の発明は、タッチスイッチ調整モードでの設定内容を表示する表示手段を具備することで、スイッチ調整の設定が使用者にとって容易で、わかりやすくなる。   According to the fifth aspect of the present invention, by providing the display means for displaying the setting contents in the touch switch adjustment mode, the switch adjustment setting is easy for the user and easy to understand.

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は、本発明の第1の実施の形態における加熱調理器の構成図を示すものである。
(Embodiment 1)
FIG. 1 shows a configuration diagram of a heating cooker according to the first embodiment of the present invention.

図1において、外郭構成する本体1の上面に天板2が設けられ、天板2上に搭載置された被加熱物を加熱するため、本体左側の天板2の下部には誘導加熱手段である左加熱コイル3a、本体右側の天板2の下部には誘導加熱手段である右加熱コイル3bが設けられている。左加熱コイル3a及び右加熱コイル3bは、コイルに高周波電流を流し磁界を発生させることで当該加熱コイル上部の被加熱物を誘導加熱している。更に、天板2と略同一面上には、加熱の入切を制御するタッチスイッチである左加熱切/入スイッチ6a、右加熱切/入スイッチ6b及び加熱の出力の調整を行う左ダウンスイッチ7a1、左アップスイッチ7a2、右ダウンスイッチ7b1、右アップスイッチ7b2が設けられ、各スイッチの直前には左右それぞれの加熱手段の動作状態や設定状態を表示する左液晶表示装置5a、右液晶表示装置5bがそれぞれ設けられている。また、本体前方側面には、左加熱部のタイマ設定を左タイマスイッチ11aと右加熱部のタイマ設定を右タイマスイッチ11bと機器の電源をオンオフするための電源スイッチ11cが設けられている。   In FIG. 1, a top plate 2 is provided on the upper surface of the main body 1 constituting the outer shell, and an object to be heated mounted on the top plate 2 is heated by an induction heating means at the lower part of the top plate 2 on the left side of the main body. A left heating coil 3a and a right heating coil 3b as induction heating means are provided below the top plate 2 on the right side of the main body. The left heating coil 3a and the right heating coil 3b inductively heat an object to be heated above the heating coil by causing a high frequency current to flow through the coil and generating a magnetic field. Further, on substantially the same surface as the top plate 2, a left heating off / on switch 6a, a right heating off / on switch 6b, which are touch switches for controlling heating on / off, and a left down switch for adjusting heating output. 7a1, a left up switch 7a2, a right down switch 7b1, and a right up switch 7b2 are provided, and immediately before each switch, a left liquid crystal display device 5a and a right liquid crystal display device for displaying the operating state and setting state of the left and right heating means, respectively. 5b are provided. Further, on the front side surface of the main body, there are provided a left timer switch 11a for setting the timer for the left heating unit, a timer setting for the right heating unit for the right timer switch 11b, and a power switch 11c for turning on / off the device.

またさらに、天板2の下側には、タッチスイッチの検知方式を制御する制御手段4と、タッチスイッチの実際のスイッチ検知電圧(V1−V2)を記憶する記憶手段8と、タッチスイッチのスイッチ検知電圧しきい値(Vθ)を切り替える電圧切替手段9と、機器がタッチスイッチ調整モードへの移行時もしくは、タッチスイッチ調整モードで設定が完了した際、そのことを報知する報知手段10を備えている。   Furthermore, below the top plate 2, a control means 4 for controlling the touch switch detection method, a storage means 8 for storing the actual switch detection voltage (V1-V2) of the touch switch, and a switch for the touch switch Voltage switching means 9 for switching the detection voltage threshold value (Vθ), and notification means 10 for notifying when the device is shifted to the touch switch adjustment mode or when the setting is completed in the touch switch adjustment mode are provided. Yes.

ここで、本実施の形態では、誘導加熱手段、加熱切/入スイッチ、アップスイッチ、ダウンスイッチ、液晶表示装置を左、右にそれぞれ独立して備えており、前述の構成要素は左ブロック、右ブロック単位で同一の作用を行なうため、右ブロックの説明は省略し左ブロックの説明で代用する。   Here, in the present embodiment, the induction heating means, the heating off / on switch, the up switch, the down switch, and the liquid crystal display device are provided independently on the left and right, respectively, and the above-mentioned components are the left block, the right Since the same operation is performed in units of blocks, description of the right block is omitted and description of the left block is substituted.

図2は、左スイッチの詳細構成とスイッチ検知信号を図示したものであり、各スイッチは導電性の表電極と裏電極とで、絶縁物(ここではガラスとする)で構成される天板2を挟み込んだコンデンサ構成となっている。表電極は使用者が容易に操作できるよう、天板2の外郭と同一面上に形成されており、表電極に人の指が触れると、前述したコンデンサ構造部に蓄えられていた電荷が人体を介して大地に放電されることから、図2に示すようにスイッチ検知電圧がv1からv2に変動する。スイッチの受付は、制御手段4で、あらかじめ設定されたスイッチ検知電圧Vθを超える変動電圧が、あらかじめ設定されたスイッチ検知時間tθの間連続して入力された時に有効としている。左加熱切/入スイッチ6aに人が触れると、その信号は制御手段4に入力され、制御手段4により左加熱コイル3aの加熱オンオフの制御及び左液晶表示装置5aの動作状態表示を行う。   FIG. 2 shows a detailed configuration of the left switch and a switch detection signal. Each switch is composed of a conductive front electrode and a back electrode, and a top plate 2 made of an insulating material (here, glass). It has a capacitor configuration with The surface electrode is formed on the same surface as the outer surface of the top plate 2 so that the user can easily operate it. When a person's finger touches the surface electrode, the charge stored in the capacitor structure described above is transferred to the human body. Therefore, the switch detection voltage varies from v1 to v2 as shown in FIG. The acceptance of the switch is valid when the control means 4 continuously inputs a variable voltage exceeding a preset switch detection voltage Vθ for a preset switch detection time tθ. When a person touches the left heating off / on switch 6a, the signal is input to the control means 4, and the control means 4 controls heating on / off of the left heating coil 3a and displays the operating state of the left liquid crystal display device 5a.

左ダウンスイッチ7a1、左アップスイッチ7a2に人が触れると、その信号は制御手段4に入力され、制御手段4の働きで、左加熱コイル3aの加熱出力の増減を行う。またその際、左液晶表示装置5aの動作状態表示も併せて行う。   When a person touches the left down switch 7a1 and the left up switch 7a2, the signal is input to the control means 4, and the control means 4 functions to increase or decrease the heating output of the left heating coil 3a. At that time, the operation state of the left liquid crystal display device 5a is also displayed.

図3は、本実施の形態のタッチスイッチ調整モードにおけるスイッチ検知電圧切替の動作を示す図である。図示しているように、標準設定状態では、スイッチ検知電圧しきい値Vθを1Vとしており、スイッチに触れていない時の検知レベルV1とスイッチに触れた時の検知レベルV2の差分電圧(V1−V2)が、Vθ(1V)以上となるとスイッチ受け付けを実施する。   FIG. 3 is a diagram illustrating the switch detection voltage switching operation in the touch switch adjustment mode of the present embodiment. As shown in the figure, in the standard setting state, the switch detection voltage threshold Vθ is 1 V, and the differential voltage (V1−) between the detection level V1 when the switch is not touched and the detection level V2 when the switch is touched. When V2) becomes equal to or higher than Vθ (1V), switch reception is performed.

次に、左タイマスイッチ11aを押した状態で電源スイッチ11cをオンすると、機器は報知手段10により音による報知を行うと共にタッチスイッチ調整モードへ移行する。   Next, when the power switch 11c is turned on while the left timer switch 11a is pressed, the device notifies the sound by the notification means 10 and shifts to the touch switch adjustment mode.

移行時は、左液晶表示装置5aにスイッチ検知電圧しきい値Vθを意味する数字(ここでは1)が表示される。そしてその後、記憶手段8にあらかじめ格納された実際の検知レベル(V1−V2)に基づいて、自動的にスイッチ検知電圧しきい値Vθが再設定される。実施例においては、(V1−V2)が0.5V以上0.75V未満の時はVθを0.25V、0.75V以上1.25V未満の時はVθを0.5V、1.25V以上1.75V未満の時はVθを1.0V、1.75V以上0.75の時はVθを1.25Vとして左液晶表示装置5aに表示している。Vθが再設定された後スイッチ操作が所定時間(ここでは3秒)なければ、検知電圧再設定がなされた状態で通常動作モードに移行し、以後再度タッチスイッチ調整モードに移行させない限り、タッチスイッチは再設定されたしきい値Vθで動作する。また、前述のタッチスイッチ調整モードから通常動作モードへ移行する所定時間(3秒)の間に、アップスイッチもしくはダウンスイッチが入力されると、Vθの値を使用者がマニュアルでも変更させることができ、本実施例では、0.25Vの設定を0.5Vに、0.5Vの設定を0.25V〜0.75V、1.0Vの設定を0.75V〜1.25V、1.25Vの設定を1.0V〜1.5Vに再設定する動作例を示している。前記マニュアル設定後、やはり所定時間(ここでは3秒)操作がなければ、通常動作モードへ移行し、以降再設定されたVθでタッチスイッチは動作する。   At the time of transition, a number (here, 1) indicating the switch detection voltage threshold value Vθ is displayed on the left liquid crystal display device 5a. Thereafter, the switch detection voltage threshold value Vθ is automatically reset based on the actual detection level (V1−V2) stored in advance in the storage unit 8. In the embodiment, when (V1-V2) is 0.5 V or more and less than 0.75 V, Vθ is 0.25 V, and when (V1 to V2) is 0.75 V or more and less than 1.25 V, Vθ is 0.5 V, 1.25 V or more and 1 When it is less than .75 V, Vθ is 1.0 V, and when it is 1.75 V or more and 0.75, Vθ is 1.25 V and displayed on the left liquid crystal display device 5a. If the switch operation is not performed for a predetermined time (3 seconds in this case) after Vθ is reset, the touch switch is changed to the normal operation mode with the detection voltage reset, and then to the touch switch adjustment mode again. Operates at the reset threshold value Vθ. In addition, if the up switch or the down switch is input during the predetermined time (3 seconds) for shifting from the touch switch adjustment mode to the normal operation mode, the user can manually change the value of Vθ. In this embodiment, the setting of 0.25V is set to 0.5V, the setting of 0.5V is set to 0.25V to 0.75V, the setting of 1.0V is set to 0.75V to 1.25V, and 1.25V. Shows an example of the operation of resetting V to 1.0V to 1.5V. After the manual setting, if there is no operation for a predetermined time (here, 3 seconds), the operation shifts to the normal operation mode, and thereafter the touch switch operates at the reset Vθ.

以上のように本実施の形態では、検知レベル(設定電圧)を実際の検知レベルに合わせて自動的に再設定でき、意図しないスイッチ受付を防止し且つ操作性を損なわない最適な検知性能を使用者の使用実態に合わせて設定でき使い勝手がよい。   As described above, in the present embodiment, the detection level (set voltage) can be automatically reset according to the actual detection level, and the optimum detection performance that prevents unintended switch reception and does not impair operability is used. It can be set according to the actual usage of the user and is easy to use.

スイッチ検知レベル(設定電圧)は、設定電圧が小さければ検知が敏感になり、例えばタッチスイッチ回りを拭き掃除する時や調理物のタッチスイッチ近傍への飛び散り等で、意図せずスイッチ受付してしまうという側面と、設定電圧が大きいと、使用者が意図してスイッチ操作した時の検知性能が鈍くなり操作の仕方によってはスイッチが入りずらく使い勝手が悪くなるといった側面をもちあわせている。本発明では、前述した排他的側面を両立させた最適な反応時間が自動的に設定可能となるため使い勝手は格段に向上する。また、検知レベルの自動再設定に加えて更に、使用者によるマニュアル設定を併せ持つことで、微妙な設定再設定も可能でありさらい使い勝手は向上する。   The switch detection level (set voltage) is sensitive to detection if the set voltage is small. For example, the switch is unintentionally accepted when wiping around the touch switch or when the food is scattered near the touch switch. When the set voltage is large, the detection performance when the user operates the switch is dull, and depending on the operation method, the switch is difficult to enter and the usability is poor. In the present invention, since the optimum reaction time in which the above-described exclusive aspects are compatible can be automatically set, the usability is greatly improved. Further, in addition to automatic resetting of the detection level, manual setting by the user is also provided, so that delicate setting resetting is possible and the usability is improved.

また、特に本実施の携帯にある様に誘導加熱を有した加熱調理器においては、誘導加熱時の際に発生する磁力線の影響でスイッチ検知の電器信号が変化する可能性があり、前述の影響を検知電圧を設定変更することによって回避し、使い勝手向上することができる。   In particular, in a cooking device having induction heating as in the case of the present embodiment, the electric signal for switch detection may change due to the influence of magnetic lines generated during induction heating. Can be avoided and the usability can be improved by changing the setting of the detection voltage.

また、さらに加熱部と同一面上にスイッチが配置された本発明の場合、調理物や調理機材をスイッチ部に置いてしまったり、接触させてしまったりする可能性は高く、検知電圧を切替調整できる利便性は特に高い。   In addition, in the case of the present invention in which the switch is arranged on the same surface as the heating unit, there is a high possibility that the food or cooking equipment will be placed on or contacted with the switch unit, and the detection voltage is switched and adjusted. The convenience that can be done is particularly high.

また、検知差分電圧は、スイッチを操作する使用者の人体内部抵抗や人体静電容量また、機器の設置状況、機器の周辺設置環境によっても変動し、また、人体以外の調理物や水がタッチスイッチ回りに付着することによっても変動する。本発明は、検知所定電圧を設定可能であるため、使用者の人体の個別差、機器の設置環境の差異による差分電圧の違いを補間でき、個別に最適な検知性能を実現できるため使い勝手がよい。また、検知所定電圧の設定調整で、調理中の水、調理物の飛び散りによるスイッチ誤検知防止も、操作性とのバランスの中で設定することができ使い勝手がよい。   The detection differential voltage also varies depending on the internal resistance and capacitance of the user who operates the switch, the installation status of the device, and the surrounding installation environment of the device. It also fluctuates by sticking around the switch. In the present invention, since the predetermined detection voltage can be set, it is possible to interpolate the difference in the difference voltage due to the individual difference of the user's human body and the difference in the installation environment of the device, and the optimum detection performance can be realized individually, which is convenient. . In addition, by setting and adjusting the detection predetermined voltage, prevention of erroneous switch detection due to splashing of water during cooking or cooking can be set in a balance with operability, which is convenient.

尚、本実施の形態では、タッチスイッチ検知モードへの移行は、通常使用時は、機器の別の制御を司る既存スイッチの組み合わせ操作で行えるものとし、専用のモード移行スイッチを有しない安価性の効果のあるものとして説明したが、専用スイッチの具備もしくは、通常使用では露出しない部分への移行スイッチの設置をおこなったとしても、安価性、設定の容易さ以外は同等の効果が得られる。   In the present embodiment, the transition to the touch switch detection mode can be performed by a combination operation of existing switches that control different devices during normal use, and does not have a dedicated mode transition switch. Although described as effective, even if a dedicated switch is provided or a transition switch is installed in a portion that is not exposed in normal use, the same effects can be obtained except for the low cost and ease of setting.

また尚、本実施の形態では、加熱部を誘導加熱として説明したが、加熱部は電熱加熱、ラジェントヒータ加熱、ガス加熱であっても同等の効果が得られる。   In the present embodiment, the heating unit is described as induction heating. However, even if the heating unit is electric heating, radial heater heating, or gas heating, the same effect can be obtained.

尚、本実施の形態では、タッチスイッチ調整モードへの移行を、タッチスイッチである左タイマスイッチと電源スイッチの組み合わせ動作により移行するとしているが、他のスイッチの組み合わせ動作であっても同等の効果が得られる。   In this embodiment, the transition to the touch switch adjustment mode is performed by the combination operation of the left timer switch and the power switch that is a touch switch. However, the same effect can be obtained by the combination operation of other switches. Is obtained.

以上のように、本発明にかかる加熱調理器は、機器の動作状態に応じてタッチスイッチの検知レベルを切り替えることで、天面上に操作スイッチを配した機器の使い勝手を向上することができるので、電熱加熱、誘導加熱のみならずガス加熱調理器の用途にも適用できる。   As described above, the cooking device according to the present invention can improve the usability of the device having the operation switch on the top surface by switching the detection level of the touch switch according to the operation state of the device. It can be applied not only to electric heating and induction heating but also to gas cooking devices.
