Description

本発明は一般家庭で使用する加熱調理器に関するものである。   The present invention relates to a heating cooker used in general households.

従来、この種の加熱調理器は、トッププレート上の表示部や操作部に高温の調理容器が載置された場合、電源の切断または注意を喚起する構成となっていた（例えば、特許文献１参照）。   Conventionally, this type of cooking device has been configured to call off the power or call attention when a high-temperature cooking container is placed on the display unit or operation unit on the top plate (for example, Patent Document 1). reference).

図７は、同公報に記載された従来の加熱調理器の斜視図である。   FIG. 7 is a perspective view of a conventional cooking device described in the publication.

図において、加熱調理器の本体の上面には耐熱性ガラス製のトッププレート１がトップフレーム２により外周部を覆われ配設されている。その手前側左右と、中央奥側に加熱部３を配している。また、４はトッププレート１の手前側に夫々の加熱部３に対応して設けた静電容量式タッチキーの操作部であり、加熱時に加熱部に載置された加熱調理容器の一部が操作部４またはその近辺に載置され、操作部４が熱の影響を受け異常に高温になった時、電源を切ったり注意を喚起する表示をしたりブザー報知をしたりするものであった。
特開２００３−１３３０４２号公報 In the figure, a top plate 1 made of heat-resistant glass is disposed on the upper surface of the main body of the heating cooker with its outer peripheral portion covered by a top frame 2. The heating unit 3 is arranged on the front left and right sides and the center back side. Reference numeral 4 denotes an operation unit of a capacitive touch key provided on the front side of the top plate 1 corresponding to each heating unit 3, and a part of the cooking container placed on the heating unit at the time of heating is provided. When the operation unit 4 is placed at or near the operation unit 4 and becomes abnormally hot under the influence of heat, it turns off the power, displays a warning, or gives a buzzer notification. .
JP 2003-133042 A

しかし、前記の従来の構成では電源を切ったり注意を喚起するだけで、表示素子の温度を積極的の下げることはなかった。   However, the conventional configuration described above does not actively lower the temperature of the display element only by turning off the power or calling attention.

そこで、本発明は温度検知部の温度が上昇するのを検知して送風機を駆動または風量を増大させることにより表示素子等の表示部の温度が上昇しないことと、調理容器が操作部に近づいて表示部の温度が上昇するということは、調理容器がキーに当たって、不用意に操作キーが動作する可能性が高くなり、不用意に操作キーが動作することを未然に防止する事を目的とする。   Therefore, the present invention detects that the temperature of the temperature detection unit rises and drives the blower or increases the air volume, so that the temperature of the display unit such as the display element does not rise, and the cooking container approaches the operation unit. The rise in the temperature of the display unit is intended to prevent the operation key from being inadvertently operated by increasing the possibility that the operation key will inadvertently operate when the cooking container hits the key. .

この目的を達成する為に、本発明の加熱調理器は、筐体の上面に設けた電気絶縁性を有する板状部材のトッププレートと、被加熱物を加熱する手前側に２つ、中央奥側に１つ設けた加熱部と、前記トッププレート上に前記手前側加熱部に対応して設けられた、使用者が操作情報を入力するための静電容量方式のタッチキーによる操作部及び動作状態を表示するための液晶表示素子による表示部と、前記液晶表示素子に冷却風を送る送風機と、前記液晶表示素子が設けられた基板と同一基板上で前記液晶表示素子の近傍に設けられかつ前記液晶表示素子の前記手前側加熱部に近い側の温度を検知する温度検知部と、前記加熱部の出力の制御および前記送風機の送風を制御する制御手段とを有し、前記手前側加熱部と前記トッププレートの前縁との間で前記手前側加熱部が前記トッププレートの前縁に最も近づく部分に位置しかつ前記操作部が前記表示部よりも手前側に位置するように、前記表示部及び前記操作部が配置され、前記制御手段は、通常調理しているときに前記送風機を低速回転させ、前記温度検知部の温度が一定温度以上に上昇した時に前記送風機の回転数を増大させ、前記温度検知部の温度が前記一定温度よりも高い第２の温度以上になったとき加熱を停止し、異常を表示するとともに操作部のタッチキーの操作をできなくする構成とした。この構成により、使用者がうっかりして加熱調理容器を操作部の領域に載置しても操作部の温度が高温になることを防止することができる。また、トッププレート上に突起物を設ける必要がないためにトッププレートの上面を平らにすることができるようにしたものである。 To this end, the cooker of the invention, the top plate of the plate-like member having an electrical insulating property provided on the upper surface of the housing, two on the front side for heating the object to be heated, the center back One heating unit provided on the side, and an operation unit and operation by a capacitive touch key provided on the top plate corresponding to the front heating unit for inputting operation information by the user A display unit with a liquid crystal display element for displaying a state, a blower for sending cooling air to the liquid crystal display element, a substrate on which the liquid crystal display element is provided, and provided in the vicinity of the liquid crystal display element; A temperature detection unit that detects a temperature of the liquid crystal display element near the front side heating unit; and a control unit that controls output of the heating unit and air flow of the blower, and the front side heating unit And the leading edge of the top plate The display unit and the operation unit are arranged such that the front side heating unit is positioned at a portion closest to the front edge of the top plate and the operation unit is positioned on the front side of the display unit, The control means rotates the blower at a low speed during normal cooking, increases the rotational speed of the blower when the temperature of the temperature detection unit rises above a certain temperature, and the temperature of the temperature detection unit is the heating was stopped when it becomes more than a second temperature higher than a certain temperature, has a structure that eliminates possible the operation of the touch key of the operation unit displays an abnormality. With this configuration, it is possible to prevent the temperature of the operation unit from becoming high even if the user inadvertently places the cooking container in the region of the operation unit. Moreover, since it is not necessary to provide a protrusion on the top plate, the top surface of the top plate can be flattened.

また、トッププレート上の操作部に高温の調理容器が載置された場合、表示素子の近傍に設置された温度検知部の温度が上昇するのを検知して送風機の回転数を増大させることにより表示素子等の表示部の温度上昇を防止し、調理容器が操作部に近づいて表示部の温度が上昇すると言うことは、調理容器がキーに当たって、不用意に操作キーが動作する可能性が高くなるので、キー操作を無効にすることにより、不用意に操作キーが動作することを未然に防止することができる。 Further, if the cooking vessel of the high-temperature to the operating unit on the top plate is placed, as the temperature of the temperature detector installed in the vicinity of the display device increases the rotational speed of the detection to the blower from increasing When the temperature of the display unit rises by preventing the temperature of the display unit such as the display element from rising and the temperature of the display unit increases due to the cooking container approaching the operation unit, there is a high possibility that the operation key will inadvertently operate when the cooking container hits the key. Therefore, it is possible to prevent the operation keys from being inadvertently operated by disabling the key operation.

図１は本発明の実施の形態における加熱調理器をシステムキッチンに取付けた状態を示す斜視図であり、図２は同加熱調理器の要部断面図である。 (Embodiment 1)
FIG. 1 is a perspective view showing a state in which a cooking device according to an embodiment of the present invention is attached to a system kitchen, and FIG. 2 is a cross-sectional view of a main part of the cooking device.

以下、加熱調理器の構成を図１および図２を用いて説明する。図１において、加熱調理器の外郭を構成する本体の上面には耐熱性ガラス製のトッププレート１がトップフレーム２により外周部を覆われ配設されている。トッププレート１の下面には図２にあるように加熱手段３が配置されている。   Hereinafter, the configuration of the cooking device will be described with reference to FIGS. 1 and 2. In FIG. 1, a heat-resistant glass top plate 1 is covered with a top frame 2 on the upper surface of a main body constituting the outline of the heating cooker. On the lower surface of the top plate 1, heating means 3 is arranged as shown in FIG.

さらに、トッププレート１の上面には、静電容量によるタッチキー方式の操作キー４と液晶表示素子５により調理の動作状態等を表示する表示部６を有する。   Furthermore, on the upper surface of the top plate 1, there is a display unit 6 for displaying a cooking operation state or the like by a touch key type operation key 4 by a capacitance and a liquid crystal display element 5.

本実施例ではこの加熱手段３は誘導加熱によって鍋７を加熱し被調理物を加熱する誘導加熱コイル３ａ、３ｂと、誘導加熱では使えない鍋を用いて加熱するラジエントヒータ３ｃとより構成されている。   In this embodiment, the heating means 3 is composed of induction heating coils 3a and 3b for heating the cooking pot 7 by induction heating to heat the object to be cooked, and a radial heater 3c for heating using a pot that cannot be used for induction heating. Yes.

図２において、１は耐熱性ガラス製のトッププレート、３は誘導加熱コイル、４は電極８に対向する静電容量によるタッチキー方式の操作キー、６は液晶表示素子５による表示部、９は液晶表示素子５の加熱コイル３に近い側の温度を検知する温度検知部、１０は液晶表示素子５、操作部４や制御部１１の温度が上昇した時に作動してこれらを冷却する送風機である。 In FIG. 2, 1 is a heat-resistant glass top plate, 3 is an induction heating coil, 4 is a touch key type operation key based on a capacitance facing the electrode 8, 6 is a display unit by the liquid crystal display element 5, and 9 is A temperature detection unit 10 that detects the temperature of the liquid crystal display element 5 near the heating coil 3 is a blower that operates when the temperature of the liquid crystal display element 5 , the operation unit 4, or the control unit 11 rises and cools them. .

本体内には入力操作に応じて加熱手段３を制御する制御部１１が設けられている。   A control unit 11 for controlling the heating means 3 according to an input operation is provided in the main body.

以上のように構成された加熱調理器について、以下その動作と作用を説明する。   About the heating cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

操作キー４を操作しててんぷら調理や炒め物等を行うと、鍋７底部の温度は１００℃以上になる。   When the operation key 4 is operated to perform tempura cooking or fried food, the temperature at the bottom of the pan 7 becomes 100 ° C. or higher.

図３に温度検知部９の温度変化をグラフで示す。   FIG. 3 is a graph showing the temperature change of the temperature detector 9.

通常の状態で調理していると液晶表示素子５の温度は４０℃程度であるが、この鍋７を表示部６の上に乗せたりすると液晶表示素子５の温度は上昇し、正常な表示ができなくなったり耐久性が低下したりするので、制御部１１（制御手段）は、これを温度検知部９で検知し約８０℃になったところで温度検知部９により異常を検知し送風機１０を高速作動させて冷風を送り液晶表示素子５の温度を下げる。   When cooking in a normal state, the temperature of the liquid crystal display element 5 is about 40 ° C. However, when the pan 7 is placed on the display unit 6, the temperature of the liquid crystal display element 5 rises and a normal display is obtained. The control unit 11 (control means) detects this with the temperature detection unit 9 and detects an abnormality with the temperature detection unit 9 when the temperature detection unit 9 reaches about 80 ° C. The liquid crystal display element 5 is lowered in temperature by operating and sending cool air.

送風機１０は制御部１１の冷却にも使用しているので、調理を行っている通常は既に低速で回っている状態にあり、この状態で温度検知部９の温度が約８０℃になった場合は送風機１０の回転速度を増大させ、高速回転させて液晶表示素子５の温度を下げる。   Since the blower 10 is also used for cooling the control unit 11, cooking is usually already performed at a low speed, and the temperature of the temperature detection unit 9 becomes about 80 ° C. in this state. Increases the rotational speed of the blower 10 and rotates it at a high speed to lower the temperature of the liquid crystal display element 5.

（参考の形態１）
図２において、てんぷら調理や炒め物等を行った鍋７の温度が非常に高く、これを表示部６の上に乗せてさらに放置すると、液晶表示素子５の温度は送風機１０を作動させてもさらに温度が上昇する場合があり、図４に示すように、この温度が第２の温度約９０℃に達すると加熱を停止し、ブザーで異常報知を行い、表示部６に異常を示す表示を行う。 ( Reference form 1 )
In FIG. 2, the temperature of the pan 7 where the tempura cooking or the stir-fried food is performed is very high. If the pan 7 is placed on the display unit 6 and left further, the temperature of the liquid crystal display element 5 is set to As shown in FIG. 4, when the temperature reaches the second temperature of about 90 ° C., the heating is stopped, an abnormality is notified with a buzzer, and a display indicating the abnormality is displayed on the display unit 6. Do.

（実施の形態２）
図２において、てんぷら調理や炒め物等を行った鍋７の温度が非常に高く、これを表示部６の上に乗せてさらに放置すると、液晶表示素子５の温度が上昇し、この温度が第２の温度約９０℃に達すると加熱を停止し、ブザーで異常報知を行い、表示部６に異常を示す表示を行うと共に、操作キー４を操作してもキー操作を効かなくすることにより、鍋７が操作キー４に触れて誤ったキー操作が行われるのを防止することができる。 (Embodiment 2 )
In FIG. 2, the temperature of the pan 7 where tempura cooking or fried food is performed is very high. If the pan 7 is placed on the display unit 6 and left further, the temperature of the liquid crystal display element 5 rises, and this temperature is When the temperature of 2 reaches about 90 ° C., the heating is stopped, the abnormality is notified with the buzzer, the abnormality is displayed on the display unit 6, and even if the operation key 4 is operated, the key operation is not effective. It is possible to prevent the pan 7 from touching the operation key 4 and performing an erroneous key operation.

（参考の形態２）
図２において、てんぷら調理や炒め物等を行った鍋７を表示部６の上に乗せると、特に鍋７の温度が高い場合には液晶表示素子５の温度は急激に上昇し、第１の一定温度の約８０℃で送風機１０を作動させてもさらに温度が上昇する場合があるので、図５に示すように少しでも早く鍋７が乗せられた異常状態を検知するために温度検知部９の温度が一定時間内に上昇する温度、即ち温度上昇率を検知して、例えば１秒間に１℃以上の温度上昇があった場合に送風機１０の回転速度を増大させ、高速回転させて液晶表示素子５の温度を下げる。 ( Reference form 2 )
In FIG. 2, when the pan 7 subjected to tempura cooking or fried food is placed on the display unit 6, particularly when the temperature of the pan 7 is high, the temperature of the liquid crystal display element 5 rapidly increases, and the first Even if the blower 10 is operated at a constant temperature of about 80 ° C., the temperature may further increase. Therefore, as shown in FIG. 5, the temperature detector 9 detects the abnormal state where the pan 7 is placed as soon as possible. The temperature at which the temperature of the fan rises within a certain time, that is, the rate of temperature rise is detected. For example, when the temperature rises by 1 ° C. or more per second, the rotation speed of the blower 10 is increased and the liquid crystal display is rotated at a high speed. The temperature of the element 5 is lowered.

これによって、より早く異常状態を検知することができ、効果的に液晶表示素子５の温度を下げることができる。   As a result, the abnormal state can be detected earlier, and the temperature of the liquid crystal display element 5 can be effectively lowered.

（参考の形態３）
図２において、上記と同様にてんぷら調理や炒め物等を行った鍋７の温度が非常に高く、これを表示部６の上に乗せた場合、少しでも早く鍋７が乗せられた異常状態を検知するために図６に示すように温度検知部９の温度上昇率を検知する。例えば１秒間に１℃以上の温度上昇があった場合に送風機１０の回転速度を増大させ、高速回転させて液晶表示素子５の温度を下げる。しかし、鍋７の温度が高いとそれでも温度が上がり続け、この温度が第２の設定温度約９０℃に達すると加熱を停止し、ブザーで異常報知を行い、表示部６に異常を示す表示を行うと共に、キー操作を無効にする。 ( Reference form 3 )
In FIG. 2, the temperature of the pan 7 that has been cooked and fried in the same manner as described above is very high. In order to detect, the temperature rise rate of the temperature detection part 9 is detected as shown in FIG. For example, when the temperature rises by 1 ° C. or more per second, the rotation speed of the blower 10 is increased and the rotation speed is increased to lower the temperature of the liquid crystal display element 5. However, if the temperature of the pan 7 is high, the temperature continues to rise. When the temperature reaches the second set temperature of about 90 ° C., the heating is stopped, an abnormality is notified with a buzzer, and a display indicating the abnormality is displayed on the display unit 6. And disable key operation.

これによって、より早く異常状態を検知することができ、効果的に液晶表示素子５の温度を下げることができ、それでも温度が上がる場合には過熱を停止したり異常報知により、使用者に異常を知らせ、キー操作を無効にすることにより、さらに鍋７が操作キー４に触れて誤ったキー操作が行われるのを防止することができる。   As a result, the abnormal state can be detected earlier, the temperature of the liquid crystal display element 5 can be effectively lowered, and if the temperature still rises, the overheating is stopped or the abnormality is notified to the user by the abnormality notification. By informing and disabling the key operation, it is possible to further prevent the pan 7 from touching the operation key 4 and performing an erroneous key operation.

ここで、異常を検知する第１の設定温度や第２の設定温度、温度上昇率は各部品の構成によって変わるので、具体的な構成によって実験的に決める必要がある。   Here, since the first set temperature, the second set temperature, and the temperature increase rate at which an abnormality is detected vary depending on the configuration of each component, it is necessary to experimentally determine the specific configuration.

以上のように本発明にかかる加熱調理器は、タッチキーを備えた加熱調理器全般に広く応用できるものである。   As described above, the cooking device according to the present invention can be widely applied to all cooking devices having touch keys.
