A power supply circuit 63 is connected to a commercial AC power supply 61 via a door switch 62 that opens and closes contacts according to the opening and closing of the door 3. At the same time, a main control unit 64 constituted by a microcomputer is connected to the output of the power supply circuit.

又、上記メイン制御部64の出力ポートには、調理室2内を照明する庫内灯65を点滅駆動する庫内灯駆動回路66と、調理室2内を加熱する熱源となるガスバーナ67への燃料供給を制御する電磁弁68を駆動する電磁弁駆動回路69と、調理室2内に上記熱源の熱気を循環する循環ファン70を駆動する循環ファン駆動回路71と、調理室2内に他の熱源となる高周波電波を供給するマグネトロン72を駆動するマグネトロン駆動回路73と、上記ガスバーナ67点火用の点火回路74と、上記操作パネル4を電動により斜めに傾動するギヤードモータ11を駆動するモータ駆動回路75と、上記表示器20を駆動する表示回路76を接続し、同じく入力ポートには、扉3の開閉を検出するドア開閉検出回路77の出力と、上記操作基板49に配置した電極50・・による各タッチキー26・・の入力を検出するキー入力回路78の出力と、上記調理室2内の温度をサーミスタ79の出力により検出する庫内温度検出回路80の出力とを接続し、同じく入出力ポートには、ガスバーナ67の点火を検出する炎検出回路81と、データ記憶用のメモリ82を接続している。   Further, the output port of the main control unit 64 is connected to an interior lamp driving circuit 66 for driving the interior lamp 65 for illuminating the interior of the cooking chamber 2 and a gas burner 67 serving as a heat source for heating the interior of the cooking chamber 2. An electromagnetic valve drive circuit 69 for driving an electromagnetic valve 68 for controlling fuel supply, a circulation fan drive circuit 71 for driving a circulation fan 70 for circulating the hot air of the heat source in the cooking chamber 2, and another in the cooking chamber 2 A magnetron driving circuit 73 that drives a magnetron 72 that supplies high-frequency radio waves serving as a heat source, an ignition circuit 74 for igniting the gas burner 67, and a motor driving circuit that drives a geared motor 11 that tilts the operation panel 4 electrically by driving. 75 and a display circuit 76 for driving the display device 20 are connected, and the output of the door opening / closing detection circuit 77 for detecting the opening / closing of the door 3 is connected to the input port and the operation board. The output of the key input circuit 78 for detecting the input of each touch key 26... By the electrodes 50... Disposed in the 9 and the internal temperature detection circuit 80 for detecting the temperature in the cooking chamber 2 by the output of the thermistor 79. Similarly, a flame detection circuit 81 for detecting the ignition of the gas burner 67 and a memory 82 for data storage are connected to the input / output port.

尚、83は上記メイン制御部64の出力ポートに接続した自己保持用の電磁リレー駆動回路で、その出力にて上記ドアスイッチ62に並列接続した自己保持用のリレー接点84を駆動するもので、扉3が開かれてドアスイッチ62が閉じ、電源回路63よりメイン制御部64に通電されると、電磁リレー駆動回路83の出力にてリレー接点84を閉じ、調理の開始等により扉3が閉じてドアスイッチ62が開いても、リレー接点84を介して電源回路63に通電し、調理を継続する様に構成している。   Reference numeral 83 denotes a self-holding electromagnetic relay drive circuit connected to the output port of the main control unit 64, which drives a self-holding relay contact 84 connected in parallel to the door switch 62 by its output. When the door 3 is opened and the door switch 62 is closed and the main control unit 64 is energized from the power circuit 63, the relay contact 84 is closed by the output of the electromagnetic relay driving circuit 83, and the door 3 is closed by starting cooking or the like. Even if the door switch 62 is opened, the power supply circuit 63 is energized via the relay contact 84 to continue cooking.

又、上記メイン制御部64は、調理が終了して所定時間経過した場合や、扉3が閉じられてから所定時間経過しても操作部21に配置した各タッチキー26・・の入力操作が無い場合には、上記リレー接点84を開いて電源回路63への通電を遮断し、所謂待機時には電力を消費しない様に構成している。   Further, the main control unit 64 allows the input operation of each touch key 26... Disposed on the operation unit 21 when the predetermined time has elapsed after cooking is completed or when the predetermined time has elapsed after the door 3 is closed. If not, the relay contact 84 is opened to cut off the power supply to the power supply circuit 63 so that power is not consumed during so-called standby.

更に上記メイン制御部64は、扉3が開いて通電されると、モータ駆動回路75の出力にてギヤードモータ11を作動して操作パネル4を図2中に破線にて示す様に傾斜させ、操作部21に配置した各タッチキー26・・の操作を行ない易く構成している。   Further, when the door 3 is opened and energized, the main control unit 64 operates the geared motor 11 with the output of the motor drive circuit 75 to tilt the operation panel 4 as indicated by a broken line in FIG. The touch keys 26... Arranged on the operation unit 21 are configured to be easily operated.

一方、上記操作パネル4の傾動時には、上記操作基板49に配置した電極50・・と、操作パネル4周囲の導電性の構成部材との距離が変化する為、電極50・・の静電容量も変化するが、パネルケース9を導電部材により構成することで、図6にても示す様に、操作パネル4が移動しても電極50・・の静電容量aがキー入力回路78のキー判定閾値b以上に変化することがなく、これにより、キー入力回路78の誤動作を防止する事が出来る。   On the other hand, when the operation panel 4 is tilted, the distance between the electrodes 50... Arranged on the operation board 49 and the conductive components around the operation panel 4 changes. Although the panel case 9 is made of a conductive member, the capacitance a of the electrodes 50... Is determined by the key input circuit 78 even when the operation panel 4 is moved, as shown in FIG. There is no change beyond the threshold value b, thereby preventing the key input circuit 78 from malfunctioning.

尚、上記実施例では、静電容量のキー判定基準値と閾値を予め設定し、電極50・・の静電容量が上記閾値b以上変化した場合にキー入力有りと判定する様に構成しているが、これに限定されることなく、電極50・・の静電容量のレベルでキー入力を判定しても良い。   In the above embodiment, the key determination reference value and threshold value of the capacitance are set in advance, and when the capacitance of the electrodes 50... Changes more than the threshold value b, it is determined that there is a key input. However, the present invention is not limited to this, and the key input may be determined based on the capacitance level of the electrodes 50.

図7は本発明の他の実施例を示すもので、パネルケース9を樹脂等の非導電性部材で構成すると共に、上記電極50・・を配置した基板49の周囲であるパネルケース9の左右両側面と底面に、アルミニウムやステンレス等の導電部材から構成した薄板状の導電部材51,52を配置し、これらの導電部材により、上記図6にて示す場合と同様に、ギヤードモータ11を作動して操作パネル4を傾動しても、電極50・・の静電容量がキー入力回路78のキー判定基準値より低下することがなく、キー入力回路78の誤動作を防止するものである。   FIG. 7 shows another embodiment of the present invention. The panel case 9 is made of a non-conductive member such as resin, and the left and right sides of the panel case 9 around the substrate 49 on which the electrodes 50 are arranged. The thin plate-like conductive members 51 and 52 made of conductive members such as aluminum and stainless steel are arranged on both side surfaces and the bottom surface, and the geared motor 11 is operated by these conductive members in the same manner as shown in FIG. Thus, even if the operation panel 4 is tilted, the capacitance of the electrodes 50... Does not decrease below the key determination reference value of the key input circuit 78, thereby preventing the key input circuit 78 from malfunctioning.

一方、上記制御回路60は、図8にて示す様に、各タッチキー26・・への指bの接触や近接により各電極50・・の静電容量aの変化が、キー入力回路78にて予め設定した閾値b以上に変化することで、各タッチキー26・・の入力操作を検出する様に構成しているが、上記モータ駆動回路75の出力にてギヤードモータ11を作動して操作パネル4を傾動中には、上記各電極50・・の静電容量がキー判定基準値より低下してもキー入力を受付けない様に構成している。   On the other hand, as shown in FIG. 8, the control circuit 60 causes the key input circuit 78 to change the capacitance a of each electrode 50... By the touch or proximity of the finger b to each touch key 26. The input operation of each touch key 26... Is detected by changing to a preset threshold value b or more, but the geared motor 11 is operated by the output of the motor drive circuit 75 and operated. While the panel 4 is being tilted, no key input is accepted even if the capacitance of each of the electrodes 50... Falls below the key determination reference value.

これらの構成により、操作パネル4の傾動により各電極50・・の静電容量が変化しても、キー入力回路78が誤動作を生じることがなく、例えば上記図7にて示す導電部材51,52等が不要となり、比較的安価な構成にて、確実にキー入力回路78の誤動作を防止する事が出来るものである。   With these configurations, even if the capacitance of each electrode 50... Changes due to tilting of the operation panel 4, the key input circuit 78 does not malfunction, and for example, the conductive members 51 and 52 shown in FIG. The key input circuit 78 can be reliably prevented from malfunctioning with a relatively inexpensive configuration.

更に、上記操作パネル4の各電極50・・の静電容量は、上記実施例にて示す様にパネルケース9を導電部材により構成しない場合、例えば図9にて示す様に、操作パネル4を傾斜させた状態より電動機構12により調理器本体1内に収納すると、電極50・・の静電容量aは操作パネル4の移動に伴って低下する。   Further, the capacitance of each electrode 50... Of the operation panel 4 is such that when the panel case 9 is not composed of a conductive member as shown in the above embodiment, the operation panel 4 is shown in FIG. When the electric mechanism 12 is housed in the cooker body 1 from the inclined state, the capacitance a of the electrodes 50... Decreases as the operation panel 4 moves.

そこで、キー入力回路78にて予め設定した通常のキー判定閾値1cに基づいてキー入力を判定した場合、上記操作パネル4の傾動による静電容量の変化でキー入力の誤動作を生じる為、操作パネル4の収納開始と共に上記キー入力回路78のキー判定閾値をキー判定閾値2dに変更した後、操作パネル4の収納終了と共に、キー判定基準値をキー判定基準値2に変更する様に構成している。尚、キー判定基準値2に変更した後は、各電極50・・の静電容量がキー判定閾値1c以上変化した否か判定し、変化時にはキー入力有りと判定する。   Therefore, when the key input is determined based on the normal key determination threshold value 1c set in advance by the key input circuit 78, a malfunction of the key input occurs due to a change in capacitance due to the tilt of the operation panel 4. The key determination threshold value of the key input circuit 78 is changed to the key determination threshold value 2d when the storage of the key 4 is started, and then the key determination reference value is changed to the key determination reference value 2 when the operation panel 4 is stored. Yes. After the key determination reference value 2 is changed, it is determined whether or not the capacitance of each electrode 50... Has changed by a key determination threshold value 1c or more.

これらの構成により、パネルケース9を導電材料で形成したり、操作パネル4の電極50・・周囲に導電部材51,52を設けることなく、操作パネル4の傾動によるキー入力回路78の誤動作を防止する事が出来るものである。   With these configurations, it is possible to prevent the key input circuit 78 from malfunctioning due to the tilting of the operation panel 4 without forming the panel case 9 from a conductive material or providing the conductive members 51 and 52 around the electrodes 50 of the operation panel 4. It is something that can be done.

上記実施例では操作パネル4を収納する場合について説明したが、操作パネル4を収納状態より傾斜状態に引き出す場合には、図9に示す逆の制御により、キー判定基準値やキー判定閾値を順次変更するものである。   Although the case where the operation panel 4 is housed has been described in the above embodiment, when the operation panel 4 is pulled out from the housed state to the inclined state, the key judgment reference value and the key judgment threshold value are sequentially set by reverse control shown in FIG. To change.

又、上記制御回路60は、スタートキー38がオン操作されて調理が開始されると、このスタートキーのオン操作後所定時間(例えば2秒)経過するとギヤードモータ11を反転させ、操作パネル4を垂直状態に戻す様に構成している。これにより、調理中には操作パネル4を垂直状態に戻し、操作パネルへの人体や運搬物の接触による、人体や操作パネル4の損傷を防止するものである。   When the start key 38 is turned on and cooking is started, the control circuit 60 reverses the geared motor 11 when a predetermined time (for example, 2 seconds) elapses after the start key is turned on, and the operation panel 4 is turned on. It is configured to return to the vertical state. Thereby, during cooking, the operation panel 4 is returned to a vertical state, and the human body and the operation panel 4 are prevented from being damaged by the contact of the human body and the transported object with the operation panel.

一方、調理が終了して扉3が開かれると、ドア開閉検出回路77の出力によりこれを検出してモータ駆動回路75にてギヤードモータ11を作動し、操作パネル4を傾斜させることで、次の入力操作が行ない易くなる様に構成している。   On the other hand, when cooking is finished and the door 3 is opened, this is detected by the output of the door opening / closing detection circuit 77, the geared motor 11 is operated by the motor drive circuit 75, and the operation panel 4 is tilted. It is configured to facilitate the input operation.

そして上記扉3を開いて被調理物が取り出され、扉3が閉じられると、これをドア開閉検出回路77の出力にて検出し、上記と同様に所定時間経過後に操作パネル4を垂直状態に戻す。尚、何らかの理由により、上記扉3を開いた状態で操作パネル4を垂直状態に戻したい場合には、操作パネルキー29の操作により、簡単に戻す事が出来る。   Then, when the door 3 is opened and the object to be cooked is taken out and the door 3 is closed, this is detected by the output of the door opening / closing detection circuit 77, and the operation panel 4 is brought into the vertical state after a predetermined period of time as described above. return. If for some reason it is desired to return the operation panel 4 to the vertical state with the door 3 opened, it can be easily returned by operating the operation panel key 29.

更に上記制御回路60は、操作パネル4を傾斜させた状態で、所定時間(例えば1分)経過しても操作部21に配置した各タッチキーからの入力操作が無い場合には、モータ駆動回路75にてギヤードモータ11を作動して操作パネル4を垂直状態に戻す様に構成している。   Further, when the control panel 60 is tilted and there is no input operation from each touch key arranged on the operation unit 21 even after a predetermined time (for example, 1 minute) has passed, the motor drive circuit At 75, the geared motor 11 is operated to return the operation panel 4 to the vertical state.
