Conventionally, in this type of induction heating cooker, as shown in FIG. 5, a flat top plate 1 made of a non-metal such as glass is placed on the top surface of the main body, and about 10 mm below the top plate 1. A heating coil for performing induction heating on a load such as a pan through the space, an electric heater for performing resistance heating, and the like are arranged.

JP 2001-196153 A

しかしながら、前記従来の構成では、ロースタとラジエントヒータを同時使用すると、合計の総電力量が3kW程度のなるため、例えば総電力量が4.8kWの誘導加熱調理器においては、残り1.8kWを前方の左右のバーナで分ける形となるため十分な調理ができないため、ロースタとラジエントヒータの同時使用は禁止する設計となっている。このため、ロースタを使用中に後方中央のバーナで保温調理を行うことができないなどの制約が生じ使い勝手が悪くなるという課題を有していた。   However, in the conventional configuration, if the roaster and the radiant heater are used at the same time, the total total electric energy is about 3 kW. Therefore, for example, in an induction heating cooker with a total electric energy of 4.8 kW, the remaining 1.8 kW Since it is divided by the left and right burners in front, it cannot be cooked sufficiently, so the roaster and the radiant heater are not used simultaneously. For this reason, while using a roaster, there existed a subject that restrictions, such as not being able to perform heat insulation cooking with the burner of the back center, will arise, and usability will worsen.

本発明は、前記従来の課題を解決するもので、同時使用に対する電力制限を減らすことができ、使い勝手の良い誘導加熱調理器を提供することを目的とする。   The present invention solves the above-described conventional problems, and an object thereof is to provide an induction heating cooker that can reduce power limitation for simultaneous use and is easy to use.

Therefore, it is possible to reduce the power limit for simultaneous use and to realize an easy-to-use induction heating cooker.

本発明の誘導加熱調理器は、同時使用時の制限を少なくすることができ、使い勝手の良い調理器を実現することができる。   The induction heating cooker of this invention can reduce the restriction | limiting at the time of simultaneous use, and can implement | achieve an easy-to-use cooker.

第1の発明は、本体と、前記本体の前方左部に配置された誘導加熱コイルと、前記本体の前方右部に配置された誘導加熱コイルと、前記本体の後方中央部に配置された誘導加熱コイルと、前記誘導加熱コイルに高周波電流を供給するインバータと、電気抵抗式加熱手段を有するロースタと、前記インバータおよび前記電気抵抗式加熱手段の出力を制御する制御部とを備え、前記ロースタは電源と前記抵抗式加熱手段の間に設けたリレー手段をオン・オフすることで電力制御を行うことにより、ロースタと他の誘導加熱コイルを含むバーナの同時使用を行っても従来のラジエントヒータを使った場合に較べ、誘導加熱バーナが連続的な制御ができるため、総電力量を少なく抑えることができ同時使用に対する電力制限を減らすことができ、使い勝手の良い誘導加熱調理器とすることができる。   1st invention is a main body, the induction heating coil arrange | positioned in the front left part of the said main body, the induction heating coil arrange | positioned in the front right part of the said main body, and the induction arrange | positioned in the back center part of the said main body.

Compared to the case where a conventional radiant heater is used, the induction heating burner can be controlled continuously, and the resistance heating means in the roaster is divided into upper and lower parts and individually controlled. When heating is performed only on one side, the total amount of electric power can be suppressed to a low level, and the power limit for simultaneous use can be reduced, so that an induction heating cooker that is easy to use can be obtained.

A resistance heating means for the catalyst, and a relay means is provided between the upper resistance heating means, the lower heating means, the catalyst resistance heating means and the power source, and the relay means is independently turned on / off. By controlling the power, the induction heating burner can be controlled continuously even when the burner including the roaster and other induction heating coils is used at the same time, compared to the case where the conventional radiant heater is used. By dividing the resistance heating means into multiple parts and controlling them individually, the total amount of power can be reduced when heating with a part of the resistance heating means. Can be reduced, it can be user-friendly induction heating cooker.

第4の発明は、電気抵抗式加熱手段に出力を行った場合は、制御部は、インバータへの出力が定格以下になるように制限することにより、熱源の同時使用時に総電力量を制限するとともに自動メニューの使用が多いロースタ部の電力量を優先することにより、調理性能を安定させることができ使い勝手の良い誘導加熱調理器とするものである。   In the fourth aspect of the invention, when the output is made to the electric resistance heating means, the control unit restricts the total electric energy at the time of simultaneous use of the heat source by restricting the output to the inverter to be below the rating. At the same time, priority is given to the amount of power of the roaster section, which often uses an automatic menu, so that the cooking performance can be stabilized and the induction heating cooker is easy to use.

第5の発明は、ロースタは、予め選択された調理メニューに応じ制御部が前記ロースタへの電気抵抗式加熱手段の出力をオン・オフにて制御する自動調理機能を備え、自動調理中は前記制御部は前記インバータの出力が一定値以下になるように出力を制限することにより、熱源の同時使用時に総電力量を制限するとともに自動メニューの使用が多いロースタ部の電力量を優先することにより、調理性能を安定させることができ使い勝手の良い誘導加熱調理器とするものである。   According to a fifth aspect of the invention, the roaster has an automatic cooking function in which the control unit controls the output of the electric resistance heating means to the roaster on and off according to a preselected cooking menu, and the automatic cooking function is performed during automatic cooking. By limiting the output so that the output of the inverter is below a certain value, the control unit limits the total power amount when using the heat source at the same time and gives priority to the power amount of the roaster unit that often uses the automatic menu. The cooking performance can be stabilized, and the induction heating cooker is easy to use.

第6の発明は、ロースタは、予め選択された調理メニューに応じ制御部が前記ロースタへの電気抵抗式加熱手段の出力をオン・オフにて制御する自動調理機能を備え、自動調理中は前記制御部は前記抵抗式加熱手段の出力に応じて前記インバータへの出力制限値を変更することにより、同時使用に対する電力制限をより減らすことができ、使い勝手の良い誘導加熱調理器とすることができる。   According to a sixth aspect of the invention, the roaster has an automatic cooking function in which the control unit controls the output of the electric resistance heating means to the roaster on and off according to a preselected cooking menu, and the automatic cooking function is performed during automatic cooking. The control unit can reduce the power limit for simultaneous use by changing the output limit value to the inverter in accordance with the output of the resistance heating means, and can be an easy-to-use induction heating cooker. .

第7の発明は、本体後方中央部に配置された誘導加熱コイルは、予め選択された調理メニューに応じ制御部が前記後方中央部に配置された誘導加熱コイルの出力を制御する自動調理機能を備え、自動調理中は前記制御部は前方左部及び右部に配置された加熱コイルへの出力が一定値以下になるようにインバータの出力を制限することにより、自動調理メニューで調理中の該当コイル上での調理ができなくなることを防止することができるため、使い勝手の良い誘導加熱調理器とすることができる。   According to a seventh aspect of the present invention, the induction heating coil disposed in the rear central part of the main body has an automatic cooking function in which the control unit controls the output of the induction heating coil disposed in the rear central part according to a preselected cooking menu.

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)
本発明の第1の実施の形態について図面を参照しながら説明する。
(Embodiment 1)
A first embodiment of the present invention will be described with reference to the drawings.

図1は本発明の第1の実施の形態における誘導加熱調理器の構成を示す図であり、図2は各構成要素の接続を示す図である。   FIG. 1 is a diagram showing the configuration of the induction heating cooker according to the first embodiment of the present invention, and FIG. 2 is a diagram showing the connection of each component.

図1において、本体8の天面はガラスなどの非金属で構成された平坦な天板1が置かれ、調理物が入った鍋などの負荷が置かれる。天板1の下部には約10mmほどの空間を介して鍋などの負荷に誘導加熱を行うための誘導加熱コイルが配置される。誘導加熱コイルは、本体の前方の左右に配置される前方左部誘導加熱コイル2と前方右部誘導加熱コイル3が配置され、更に中央奥には中央奥部誘導加熱コイル4が配置される。また、誘導加熱コイルの下部には電気抵抗式のヒータを持ったロースタ6と、誘導加熱コイルに高周波電力を供給するインバータ5と、インバータ5及びロースタ6の電力量を制御する制御部7が配置される。   In FIG. 1, a flat top plate 1 made of a non-metal such as glass is placed on the top surface of the main body 8, and a load such as a pan containing food is placed. An induction heating coil for performing induction heating on a load such as a pan through a space of about 10 mm is disposed below the top plate 1. The induction heating coil includes a left front induction heating coil 2 and a right front induction heating coil 3 disposed on the left and right in front of the main body, and a central back induction heating coil 4 disposed further in the center. A roaster 6 having an electric resistance heater, an inverter 5 for supplying high-frequency power to the induction heating coil, and a control unit 7 for controlling the amount of power of the inverter 5 and the roaster 6 are disposed below the induction heating coil. Is done.

図2に示すように前方左部誘導加熱コイル2、前方右部誘導加熱コイル3及び中央奥部誘導加熱コイル4にはインバータ5が接続され、制御部7はインバータに電力指令を与えることにより電力量を制御している。また、ロースタ6の電力量は制御部7がロースタ6内の抵抗式加熱手段9をリレー切替手段13の入り切りすることにより制御される。   As shown in FIG. 2, an inverter 5 is connected to the front left induction heating coil 2, the front right induction heating coil 3, and the center back induction heating coil 4, and the control unit 7 supplies power by giving a power command to the inverter. The amount is controlled. Further, the amount of power of the roaster 6 is controlled by the control unit 7 turning on and off the resistance heating means 9 in the roaster 6 with the relay switching means 13.

ところで、ロースタ6内の抵抗式加熱手段9の電力制御は、ヒータの入り切りによる制御であるため、ロースタ6の使用時にはロースタ6の最大電力を確保する必要がある。一方、誘導加熱を用いたバーナにおいては入力電力量を連続的に設定できるため、加熱に必要な電力量を確保すれば良い特徴がある。ここで、中央奥部のバーナにおいては使用者からの距離が遠いため、通常は煮込みや保温などの連続的かつ火力の小さい調理を行うことが多く、そのためロースタを使用してかつ中央奥部のバーナを使用する状況が望まれる。また、前方左部誘導加熱コイル2及び前方右部誘導加熱コイル4をもった左右バーナにおいては炒め物などの高火力の調理を行うような使用状況が望まれることになる。   By the way, since the power control of the resistance heating means 9 in the roaster 6 is control by turning on and off the heater, it is necessary to secure the maximum power of the roaster 6 when the roaster 6 is used. On the other hand, in the burner using induction heating, since the input electric energy can be set continuously, there is a feature that the electric energy necessary for heating may be ensured. Here, in the burner at the back of the center, because the distance from the user is far, usually, continuous cooking with low thermal power, such as stew and heat insulation, is often performed. A situation where a burner is used is desired. Moreover, in the left and right burners having the front left part induction heating coil 2 and the front right part induction heating coil 4, a use situation in which cooking with high heating power such as fried food is performed is desired.

よって、中央奥部のバーナを中央奥部誘導加熱コイル2による誘導加熱バーナとすることにより、中央奥のバーナの連続的な電力制御が可能となり、ロースタ6との同時使用時においても最大電力量を制限することで他のバーナの電力量を大きく制限することなく、同時調理を行うことが可能となる。また、連続的に電力を変化させることができるため従来のラジエントヒータに較べ、調理性能を向上させることが可能となる。   Therefore, by using the central back burner as the induction heating burner by the central back induction heating coil 2, continuous power control of the central back burner is possible, and the maximum amount of power can be obtained even when used simultaneously with the roaster 6. By limiting the amount of power, it becomes possible to perform simultaneous cooking without greatly limiting the amount of power of the other burners. Moreover, since electric power can be continuously changed, it becomes possible to improve cooking performance compared with the conventional radiant heater.

なお、ロースタ6の使用時の他のバーナの電力量の制限としては、前方左右のバーナの電力量を制限しても、中央奥部のバーナの電力量を制限しても同時使用の状況が保たれるのであれば問題ない。但し、中央奥部のバーナは定格電力が小さく通常煮物などの低出力の連続調理に用いられるため、電力制限を設けず、前方左部または前方右部のバーナの電力制御を行う方が利便性が向上する。   In addition, as a restriction | limiting of the electric energy of the other burner at the time of use of the roaster 6, even if it restrict | limits the electric energy of the burner of the front left and right, or restrict | limits the electric energy of the burner of the center back, the situation of simultaneous use There is no problem if it is kept. However, since the burner at the back of the center has a small rated power and is used for continuous cooking with low output such as normal boiled food, it is more convenient to control the power of the burner at the front left part or the front right part without providing power restrictions. Will improve.

図3はロースタの具体的の構成を示す。ロースタ内は食材の上下一方もしくは両方に抵抗式加熱手段を配置する構成が取られる。ここで、上下両方に抵抗式加熱手段がある場合は、図3に示す様に食材を挟んで上部抵抗式加熱手段9a、下部抵抗式加熱手段9bの構成を取ることになる。なお、図3ではロースタ内の食材を加熱した際に発生する煙を触媒反応により分解する触媒体14と触媒体14を加熱する触媒用抵抗式加熱手段9cも併せて記載している。また図4に、制御部7がそれぞれの抵抗式加熱手段の制御するための構成を示す。上部抵抗式加熱手段9aは上部抵抗式加熱手段用リレー切替手段13aを用いて通電制御され、下部抵抗式加熱手段9bは下部抵抗式加熱手段用リレー切替手段13bを用いて通電制御され、触媒加熱用抵抗式加熱手段9cは触媒加熱用抵抗式加熱手段用リレー切替手段13cにより通電制御される。ここで、これらのリレー切替手段の通電状態に応じて、制御手段は誘導加熱コイルへの電力量を可変しながら制限することで、ロースタ使用時の各誘導加熱の総電力量の制限を少なくすることができる。なお、ロースタ内のそれぞれの抵抗式加熱手段の制御方法は調理メニューにより最適な制御方法があるため、特に限定するものではない。また、自動調理機能を備えた場合には、選択されたメニューの自動調理の状態に応じて電力制限量を変化させることで、総電力量の制限を改善させることができる。   FIG. 3 shows a specific configuration of the roaster. In the roaster, a configuration in which resistance heating means is arranged on one or both of the upper and lower sides of the food is taken. Here, when there is resistance heating means on both the upper and lower sides, as shown in FIG. 3, the upper resistance heating means 9a and the lower resistance heating means 9b are configured with foodstuffs in between. FIG. 3 also shows a catalyst body 14 that decomposes the smoke generated when the food in the roaster is heated by a catalytic reaction and a resistance heating means 9c for the catalyst that heats the catalyst body 14. FIG. 4 shows a configuration for the control unit 7 to control the respective resistance heating means. The upper resistance heating means 9a is energized and controlled using the upper resistance heating means relay switching means 13a, and the lower resistance heating means 9b is energized and controlled using the lower resistance heating means relay switching means 13b to heat the catalyst. The resistance type heating means 9c is energized and controlled by the resistance heating means relay switching means 13c for catalyst heating. Here, according to the energization state of these relay switching means, the control means limits the amount of power to the induction heating coil while varying it, thereby reducing the restriction on the total power amount of each induction heating when using the roaster. be able to. In addition, since there exists an optimal control method with a cooking menu, the control method of each resistance heating means in a roaster is not specifically limited. Moreover, when the automatic cooking function is provided, the restriction on the total electric energy can be improved by changing the electric power restriction amount in accordance with the automatic cooking state of the selected menu.

更に、本体後方中央部の配置されるバーナにおいては、使用者からの距離が遠いため、通常は煮込みや保温などの連続的かつ火力の小さい調理を行うことが多く、そのためロースタを使用してかつ本体中央奥部のバーナを使用する状況が望まれる。そのため、炊飯、煮込み、保温などの電力量が小さい自動調理メニューが本体後方中央部のバーナに搭載される場合が多い。そこで、ロースタが使用されかつ本体中央奥部のバーナが自動調理中の際には、ロースタ及び本体中央奥の電力使用を優先させ、本体前方左部及び右部のバーナの電力量を制限させることで、自動メニューの調理性能を安定させることができ、使い勝手のよい調理器を提供できることになる。なお、自動調理機能を備えた場合には、選択されたメニューの自動調理の状態に応じて電力制限量を変化させることで、総電力量の制限を改善させることができる。   Furthermore, in the burner arranged at the rear central part of the main body, since the distance from the user is far, usually continuous and small cooking such as boiling and heat retention is often performed, and therefore a roaster is used and A situation where a burner at the center back of the main body is used is desired. For this reason, an automatic cooking menu with a small amount of electric power such as rice cooking, stewing, and heat retention is often mounted on the burner at the center of the back of the main body. Therefore, when the roaster is used and the burner at the center back of the main unit is being cooked automatically, priority should be given to the use of power at the roaster and the center back of the main unit to limit the power consumption of the burner at the front left and right of the main unit. Thus, the cooking performance of the automatic menu can be stabilized, and an easy-to-use cooker can be provided. In addition, when an automatic cooking function is provided, the restriction | limiting of total electric power can be improved by changing the electric power restriction amount according to the state of the automatic cooking of the selected menu.

以上のように本実施の形態では、前方左右および中央奥にバーナをもち、かつ電気抵抗式加熱手段によるロースタを備えた誘導加熱調理器において、中央奥のバーナを誘導加熱式バーナとすることにより、ロースタと他の誘導加熱コイルを含むバーナの同時使用を行っても従来のラジエントヒータを使った場合に較べ、誘導加熱バーナが連続的な制御ができるため、総電力量を少なく抑えることができ同時使用に対する電力制限を減らすことができ、使い勝手の良い誘導加熱調理器とすることができる。   As described above, in the present embodiment, in the induction heating cooker having the burners at the front left and right and the center back and provided with the roaster by the electric resistance heating means, the burner at the center back is an induction heating type burner. Even if the burner including the roaster and other induction heating coils are used at the same time, the induction heating burner can be controlled continuously compared to the conventional radiant heater, so the total power consumption can be reduced. It is possible to reduce the power limit for simultaneous use, and to provide an easy-to-use induction heating cooker.

以上のように、本発明にかかる誘導加熱調理器は、全て誘導加熱方式のバーナで構成されたロースタ機能付き誘導加熱調理器を提供することが可能となるので、3口に限られず、4口以上の誘導加熱方式のバーナで構成されたロースタ機能付き誘導加熱調理器などの用途にも適用できる。   As described above, the induction heating cooker according to the present invention can provide an induction heating cooker with a roaster function, which is composed of all induction heating type burners. The present invention can also be applied to applications such as an induction heating cooker with a roaster function, which is composed of the above-described induction heating type burner.
