Description

本発明は、土鍋が使用できる誘導加熱調理器に関するものである。   The present invention relates to an induction heating cooker in which a clay pot can be used.

従来、この種の誘導加熱調理器としては、すでに知られている（例えば、特許文献１参照）。   Conventionally, this kind of induction heating cooker is already known (see, for example, Patent Document 1).

これは、システムキッチンのキャビネットに組み込んで使用する構成のものであり、誘導加熱手段と、誘導加熱手段の出力を設定する入力手段と、誘導加熱手段を冷却する冷却ファンと、入力手段からの入力に応じて冷却ファンの回転数を変化させる冷却ファン回転数制御手段と、誘導加熱手段を動作させる制御手段とを備え、制御手段は入力手段からの信号に応じて誘導加熱手段の出力を低下させる出力低下タイミングと冷却ファンの回転数を低下させる回転数低下タイミングに遅延時間を設けたものとなっている。このため、金属製の鍋やフライパンでは騒音を低下しながら冷却ファンの回転数を必要最低限に抑えて、発熱部品の冷却を十分維持することができる。
特開２００４−２２０９５９号公報 This is configured to be used by being incorporated in a cabinet of a system kitchen. The induction heating means, the input means for setting the output of the induction heating means, the cooling fan for cooling the induction heating means, and the input from the input means Cooling fan rotation speed control means for changing the rotation speed of the cooling fan according to the control means, and control means for operating the induction heating means. The control means reduces the output of the induction heating means in response to a signal from the input means. Delay times are provided for the output decrease timing and the rotation speed decrease timing for decreasing the rotation speed of the cooling fan.

JP 2004-220959 A

しかしながら、前記従来の構成では、２００Ｖの誘導加熱調理器では、土鍋の使用時には加熱コイル温度が上昇するために、土鍋そのものを使用禁止にしている。これは、土鍋が熱伝導率の低い土鍋生地の裏面に銀などを主成分とする薄膜からなる発熱体を設けた構成であるため、発熱体の温度が金属の鍋やフライパン使用時より高温となることがあり、特に、一旦上昇すると冷え難いことから十分な冷却性能の確保ができないことによる。また、冷却性能を確保するために冷却ファンの回転を上げると、騒音が大きくなるという問題が発生する。   However, in the above-described conventional configuration, the 200 V induction heating cooker prohibits the use of the earthenware pan itself because the heating coil temperature rises when the earthenware pan is used. This is because the earthenware pot has a heating element composed of a thin film mainly composed of silver or the like on the back of the earthenware dough with low thermal conductivity, so the temperature of the heating element is higher than when using a metal pot or frying pan. In particular, it is difficult to ensure sufficient cooling performance because it is difficult to cool once it rises. Further, when the rotation of the cooling fan is increased to ensure the cooling performance, there arises a problem that noise increases.

本発明は、前記従来の課題を解決するもので、土鍋使用時の冷却性能を向上させることができる誘導加熱調理器を提供することを目的とする。   This invention solves the said conventional subject, and it aims at providing the induction heating cooking appliance which can improve the cooling performance at the time of earthenware pot use.

前記従来の課題を解決するために、本発明の誘導加熱調理器は、制御手段が被加熱物の加熱終了後、冷却ファンを延長稼動させる土鍋対応冷却モードを有しているものである。   In order to solve the above-mentioned conventional problems, the induction heating cooker of the present invention has a clay pot cooling mode in which the control means extends the cooling fan after the heating of the object to be heated.

これによって、被加熱物の加熱終了後、冷却ファンを延長稼動させ、土鍋使用時の冷却性能を向上させることができる。また、土鍋対応冷却モードを有することで、土鍋使用時の熱伝導が悪いことによる加熱コイルの温度上昇などの問題に特化した対応が可能となるため、土鍋使用時に冷却ファンの回転数を上げたり稼動時間を延長したりしても他の被加熱物による加熱時は騒音を抑えた設定で対応することができる。   Thus, after the heating of the object to be heated, the cooling fan can be extended to improve the cooling performance when using the clay pot. In addition, by having a clay pot compatible cooling mode, it is possible to respond specifically to problems such as temperature rise of the heating coil due to poor heat conduction when using the clay pot, so the rotation speed of the cooling fan can be increased when using the clay pot Even if the operating time is extended, it is possible to cope with the setting with reduced noise when heating by another object to be heated.

By using a heating cooker, after the heating of the object to be heated, the cooling fan can be extended and the cooling performance when using the earthenware pot can be improved. In addition, by having a clay pot compatible cooling mode, it is possible to respond specifically to problems such as temperature rise of the heating coil due to poor heat conduction when using the clay pot, so the rotation speed of the cooling fan can be increased when using the clay pot Even if the operating time is extended, it is possible to cope with the setting with reduced noise when heating by another object to be heated.

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、本発明の実施の形態１における誘導加熱調理器を示している。この誘導加熱調理器はシステムキッチンのキャビネットに組み込んで使用する構成のものである。 (Embodiment 1)
FIG. 1 shows an induction heating cooker according to Embodiment 1 of the present invention. This induction heating cooker is configured to be used by being incorporated in a cabinet of a system kitchen.

図に示すように、本実施の形態における誘導加熱調理器は、外郭を構成する本体１と、鍋、フライパンなどの被加熱物を設置するプレート２と、プレート２の下方に配し被加熱物を誘導加熱する加熱コイル３ａ、３ｂおよび加熱コイル３ａ、３ｂの中央奥に位置する１口のラジェントヒータ４と、加熱コイル３ａ、３ｂの中央に位置しプレート２を介して被加熱物の温度を検知するサーミスタよりなる温度検知素子５ａ、５ｂと、前記加熱コイル３ａ、３ｂを含む内部部材を冷却するシロッコファンよりなる冷却ファン８と、前記加熱コイル３ａ、３ｂ、ラジェントヒータ４および冷却ファン８を制御する制御手段６とを備えている。そして、制御手段６は、被加熱物の加熱終了後、冷却ファン８を延長稼動させる土鍋対応冷却モードを有している。   As shown in the figure, the induction heating cooker in the present embodiment includes a main body 1 constituting an outer shell, a plate 2 on which a heated object such as a pan and a frying pan is installed, and a heated object disposed below the plate 2. Heating coils 3a and 3b for induction heating, a single heater 4 located in the center of the heating coils 3a and 3b, and the temperature of the object to be heated via the plate 2 located in the center of the heating coils 3a and 3b. Temperature detecting elements 5a and 5b made of a thermistor for detecting heat, a cooling fan 8 made of a sirocco fan for cooling an internal member including the heating coils 3a and 3b, the heating coils 3a and 3b, the radiant heater 4 and the cooling fan And control means 6 for controlling 8. And the control means 6 has the earthenware corresponding | compatible cooling mode which extends the cooling fan 8 after completion | finish of a heating of a to-be-heated material.

また、本体１の上面右後方に吸気開口部７ａを配し、上面左後方に排気開口部７ｂを設けている。さらに、本体１の前方側面には、加熱状態を表す表示部９と、加熱コイル３ａ、３ｂおよびラジェントヒータ４を動作させる操作部１０を設けている。この実施の形態では、操作部１０に、被加熱物として土鍋を使用しこれを加熱することを使用者が選択する選択手段（選択キー）１１を設けている。選択手段１１が操作されると、制御手段６の土鍋対応冷却モードが選択されるものである。   In addition, an intake opening 7a is arranged on the upper right side of the main body 1, and an exhaust opening 7b is provided on the upper left side of the upper surface. Further, on the front side surface of the main body 1, a display unit 9 that indicates a heating state and an operation unit 10 that operates the heating coils 3 a and 3 b and the radial heater 4 are provided. In this embodiment, the operation unit 10 is provided with a selection means (selection key) 11 for the user to select to use a clay pot as the object to be heated and to heat it. When the selection means 11 is operated, the clay pot corresponding cooling mode of the control means 6 is selected.

前記加熱コイル３ａは、出力定格が３ｋＷ（最大設定３ｋＷ）、加熱コイル３ｂは、出力定格が２ｋＷ（最大設定２ｋＷ）としている。また、制御手段６である制御回路部は、樹脂製のベースに固定されていて、本体１内の一側部に配置され、加熱コイル３ａ、３ｂと同様、冷却ファン８の冷却風により冷却されるようになっている。   The heating coil 3a has an output rating of 3 kW (maximum setting 3 kW), and the heating coil 3b has an output rating of 2 kW (maximum setting 2 kW). The control circuit section which is the control means 6 is fixed to the resin base and is arranged on one side of the main body 1 and is cooled by the cooling air of the cooling fan 8 like the heating coils 3a and 3b. It has become so.

次に、冷却ファン８の冷却風の流れ、および冷却ファン８の動作について説明する。   Next, the flow of cooling air from the cooling fan 8 and the operation of the cooling fan 8 will be described.

まず、被加熱物としてステンレスや鉄製などの熱伝導率が高い、例えば、熱伝導率が１００℃時に１６Ｗ／ｍ・Ｋ以上の金属製鍋を加熱する場合は、加熱開始で冷却ファン８が稼動し、プレート２の後方に設けられた吸気開口部７ａから外気が入り、冷却ファン８から吐出した空気は、制御手段６に向けて吹き付け、特に、その制御回路部にあるスイッチング素子やダイオードブリッジを冷却する構成をとっている。   First, when heating a metal pan having a high thermal conductivity such as stainless steel or iron as the object to be heated, for example, when the thermal conductivity is 16 W / m · K or more at 100 ° C., the cooling fan 8 is activated at the start of heating. Then, outside air enters from the intake opening 7a provided at the rear of the plate 2, and the air discharged from the cooling fan 8 is blown toward the control means 6, and in particular, switching elements and diode bridges in the control circuit section are connected. It is configured to cool.

その後、制御手段６上方の加熱コイル３ｂから加熱コイル３ａへ冷却風が流れ、最後に排気開口部７ｂより本体１外へ出て行く冷却風経路を形成して、加熱終了で冷却ファン８は止まるようになっている。   Thereafter, cooling air flows from the heating coil 3b above the control means 6 to the heating coil 3a, and finally forms a cooling air path that goes out of the main body 1 from the exhaust opening 7b, and the cooling fan 8 stops at the end of heating. It is like that.

一方、被加熱物として熱伝導率の低い、例えば、熱伝導率が２０〜１００℃時に１〜３Ｗ／ｍ・Ｋの粘土を焼き固めたものやセラミックなどの熱伝導率の低い土鍋を加熱する場合、鍋裏面底部に銀を主成分とする１０〜１００μｍ程度の薄膜により形成された発熱体を有するが、土鍋内に水を入れ加熱した場合でも裏面温度は水温に比べて遥かに高温度となり、加熱終了後も裏面の温度低下は遅くなる。   On the other hand, as an object to be heated, a clay pot having a low thermal conductivity, for example, a baked and hardened clay of 1 to 3 W / m · K at 20 to 100 ° C. or a ceramic having a low thermal conductivity is heated. In the case, the bottom of the pan has a heating element formed of a thin film of about 10 to 100 μm mainly composed of silver, but the back surface temperature is much higher than the water temperature even when heated in a clay pot. Even after the heating is finished, the temperature drop on the back surface becomes slow.

そこで、被加熱物として土鍋の加熱中は、冷却ファン８の回転数は最大で回転させ、さらに加熱終了後も最大回転数で延長して稼動させ、土鍋の裏面からの輻射や伝導熱によるプレート２の温度およびプレート２下の加熱コイル３ａ、３ｂの温度などを抑えて、土鍋の使用を可能としている。   Therefore, during the heating of the earthenware pot as the object to be heated, the rotation speed of the cooling fan 8 is rotated at the maximum, and further, the heating fan is extended and operated at the maximum rotation speed, and the plate is formed by radiation or conduction heat from the back of the earthenware pot. The temperature of 2 and the temperature of the heating coils 3a and 3b under the plate 2 are suppressed to enable the use of a clay pot.

冷却ファン８の延長の方法としては、加熱コイル３ａ、３ｂの温度が予め設定した温度１８０℃以下程度に低下するまで、延長冷却するのが望ましいが、加熱コイル３ａ、３ｂの温度と冷却時間との相関をとった上で、予め定めた一定時間を決めて延長することでもよい。なお、５〜１５分間の延長でほぼ１８０℃以下とすることができる。   As a method of extending the cooling fan 8, it is desirable to perform extended cooling until the temperature of the heating coils 3a and 3b is lowered to a preset temperature of about 180 ° C. or less. However, the temperature and the cooling time of the heating coils 3a and 3b It is also possible to determine and extend a predetermined time after taking the above correlation. In addition, it can be made into about 180 degrees C or less by extension for 5 to 15 minutes.

また、本実施の形態では、土鍋の使用時には使用者が選択手段１１を操作することで、被加熱物の加熱終了後、冷却ファン８を延長稼動させる土鍋対応冷却モードを選択するものであり、土鍋使用時の熱伝導が悪いことによる加熱コイル３ａ、３ｂの温度上昇などの問題に特化した個別対応が可能となる。このため、土鍋使用時に冷却ファン８の回転数を上げたり、稼動時間を延長したりしても他の被加熱物による加熱時は騒音を抑えた設定で対応することができる。   In the present embodiment, when the earthenware pot is used, the user operates the selection means 11 to select the earthenware-compatible cooling mode in which the cooling fan 8 is extended after the heating of the object to be heated. Individual correspondence specialized in problems, such as the temperature rise of heating coil 3a, 3b by the poor heat conduction at the time of earthenware pot use, is attained. For this reason, even when the number of rotations of the cooling fan 8 is increased or the operation time is extended when the earthenware pot is used, it is possible to cope with the setting with reduced noise when heating by another object to be heated.

また、冷却中であることを表示部９に表示することで、騒音の発生原因を使用者に明確に知らせることができ、不安にさせることを防止できる。特に文字にて「冷却中」と液晶表示するとわかりやすい。   In addition, by displaying on the display unit 9 that the cooling is in progress, it is possible to clearly notify the user of the cause of noise generation, and to prevent anxiety. In particular, it is easy to understand if the text “cooling” is displayed on the LCD.

（実施の形態２）
次に、本発明の実施の形態２における誘導加熱調理器について説明する。基本構成は実施の形態１と同一であるので、その説明を省略する。 (Embodiment 2)
Next, the induction heating cooker in Embodiment 2 of this invention is demonstrated. Since the basic configuration is the same as that of Embodiment 1, the description thereof is omitted.

本実施の形態では、実施の形態１のように選択手段１１を設けず、土鍋使用時に使用者が選択するのではなく、入力電流を測定して入力電力（以下、鍋入力とする。）と土鍋の温度とから土鍋であることを自動検知するようにしたものである。これにより、土鍋使用時には自動的に土鍋対応冷却モードに入り、加熱終了後も冷却ファン８を延長稼動させ、土鍋使用時の冷却性能を向上させることができる。その他は実施の形態１と同様である。   In the present embodiment, the selection means 11 is not provided as in the first embodiment, and the user does not select when using the earthenware pot, but the input current is measured and input power (hereinafter referred to as the pot input) is used. It automatically detects that it is a clay pot from the temperature of the clay pot. Thereby, when using the earthenware pot, it automatically enters the earthenware-compatible cooling mode, and the cooling fan 8 can be extended and operated even after the heating is completed, so that the cooling performance when using the earthenware pot can be improved. Others are the same as in the first embodiment.

すなわち、ステンレスや鉄製の金属製鍋に水を入れた状態で加熱した場合は、図２に示したような鍋入力と発熱体の温度との関係になり、土鍋に水を入れた状態で加熱した場合は、図３に示したような鍋入力と鍋裏面温度との関係になる。これは、金属製鍋では水により発熱体が冷却されているので、鍋入力が多くなって発熱体の温度が１００℃より少し高いレベルとなるが、土鍋では鍋入力が多くなって発熱体の温度が１００℃を遥かに越える高いレベルとなることからである。   In other words, when heated in a stainless steel or iron metal pan with water, the relationship between the pan input and the temperature of the heating element is as shown in Fig. 2, and the pan is heated with water in it. When it does, it becomes the relationship between the pan input as shown in FIG. 3, and pan back surface temperature. This is because in metal pans, the heating element is cooled by water, so the pot input increases and the temperature of the heating element is slightly higher than 100 ° C. This is because the temperature becomes a high level far exceeding 100 ° C.

つまり、鍋入力が多い場合、例えば、鍋入力が１５００Ｗ以上である場合は、土鍋の湯沸し中は発熱体の温度が２００℃以上となる。一方、金属製鍋では１５０℃以下となる。このため、鍋入力が１５００Ｗ以上である時に発熱体の温度が２００℃以上で略一定の値で水位した場合は土鍋の湯沸し中であると判別する制御を行い、土鍋の湯沸し中であるという判別時の検知後には加熱終了時点で冷却ファン８を延長稼動させて、加熱コイル３ａ、３ｂの温度を低減している。   That is, when the pot input is large, for example, when the pot input is 1500 W or higher, the temperature of the heating element is 200 ° C. or higher during boiling of the earthen pot. On the other hand, it becomes 150 degrees C or less in a metal pan. For this reason, when the pot input is 1500 W or higher and the temperature of the heating element is 200 ° C. or higher and the water level is at a substantially constant value, control is performed to determine that the earthenware pot is being heated, and that the pot is being heated. After the time is detected, the cooling fan 8 is extended at the end of heating to reduce the temperature of the heating coils 3a and 3b.

仮に、本体１の入力設定が２ｋＷであっても実際の鍋入力は２ｋＷより低くなることもあるため、入力電電流を測定し、１５００Ｗ以上であれば上述のように検知を行えば冷却性能向上に有効である。鍋入力が１５００Ｗ未満であれば、土鍋の発熱体の温度も低く抑えられるため、土鍋検知し、冷却する必要性が低くなる。このことにより、金属製鍋か土鍋かを自動判別するようにしている。   Even if the input setting of the main body 1 is 2 kW, the actual pan input may be lower than 2 kW. Therefore, if the input current is measured and if it is 1500 W or more, the detection is performed as described above, the cooling performance is improved. It is effective for. If the pot input is less than 1500 W, the temperature of the heating element of the clay pot can be kept low, so the need for detecting and cooling the clay pot is reduced. This makes it possible to automatically determine whether it is a metal pot or a clay pot.

さらに、土鍋であることを検知した時点で冷却ファン８の回転数を増加させることで、土鍋使用時の冷却性能を向上でき、土鍋をより安心して用いることを可能にすることができる。   Furthermore, by increasing the number of rotations of the cooling fan 8 when it is detected that it is a clay pot, the cooling performance when using the clay pot can be improved, and the clay pot can be used more safely.

なお、金属製鍋および土鍋の空焼き時であれば、図５および図６に示したように、温度検知素子５ａ、５ｂの検知温度により鍋入力が制御されるため、鍋入力が一定とならないし、発熱体の温度も一定とならないことから、土鍋の湯沸し中とは区別される。   If the metal pan and earthenware pan are baked, as shown in FIGS. 5 and 6, the pan input is controlled by the temperature detected by the temperature detecting elements 5a and 5b, so the pan input is not constant. However, since the temperature of the heating element is not constant, it is distinguished from the boiling of the earthenware pot.

以上のように、本発明にかかる誘導加熱調理器は、土鍋を使用して加熱できるように冷却性能を向上させることができるので、ビルトイン型および卓上、据え置き型の誘導加熱調理器の用途に適用できる。   As described above, since the induction heating cooker according to the present invention can improve the cooling performance so that it can be heated using a clay pot, it is applied to the use of built-in type, tabletop, and stationary type induction heating cookers. it can.
