　本開示は、調理用鍋などの被加熱物を誘導加熱する誘導加熱調理器に関する。 The present disclosure relates to an induction heating cooker that induction-heats an object to be heated such as a cooking pan.
　従来、誘導加熱調理器は、例えば複数の加熱コイルをトッププレートの直下に配設している。誘導加熱調理器は、加熱コイルにより、トッププレート上に載置された被加熱物である金属製の調理用鍋などを誘導加熱する。 Conventionally, in an induction heating cooker, for example, a plurality of heating coils are arranged directly under a top plate. An induction heating cooker induction-heats a metal cooking pan or the like, which is an object to be heated, placed on a top plate by a heating coil.
　また、加熱コイルにより、非接触受電装置に給電する誘導加熱調理器なども開示されている（例えば、特許文献１参照）。 Also, an induction heating cooker that feeds power to a non-contact power receiving device by a heating coil is disclosed (for example, see Patent Document 1).
　昨今、誘導加熱調理器は、利便性の、さらなる向上が求められている。 In recent years, induction heating cookers are required to further improve convenience.
　しかしながら、特許文献１の誘導加熱調理器の構成は、非接触受電装置を載置する場所が一か所に定められている。そのため、非接触受電装置をユーザの好みの位置などに配置することができない。つまり、特許文献１の誘導加熱調理器は、利便性の観点で未だ改善の余地がある。 However, in the configuration of the induction heating cooker of Patent Document 1, the place where the non-contact power receiving device is placed is determined in one place. For this reason, the non-contact power receiving device cannot be arranged at a user's favorite position or the like. That is, the induction heating cooker of Patent Document 1 still has room for improvement from the viewpoint of convenience.

　（実施の形態）
　以下に、本開示の実施の形態にかかる誘導加熱調理器について、図１および図２を用いて、説明する。 (Embodiment)
Hereinafter, an induction heating cooker according to an embodiment of the present disclosure will be described with reference to FIGS. 1 and 2.

　つまり、本実施の形態の誘導加熱調理器２のコイル１０は、被加熱物４の誘導加熱だけでなく、非接触受電装置１１の給電・充電を行う多機能コイルとして、機能する。 That is, the coil 10 of the induction heating cooker 2 according to the present embodiment functions not only as induction heating of the article to be heated 4 but also as a multi-function coil that supplies and charges the non-contact power receiving device 11.
　また、本実施の形態の誘導加熱調理器２は、備え付け表示部１２と、温度検知部１４と、発光ユニット１６（図２参照）と、制御部１８などを、さらに備える。 In addition, the induction heating cooker 2 of the present embodiment further includes an installation display unit 12, a temperature detection unit 14, a light emitting unit 16 (see FIG. 2), a control unit 18, and the like.
　以下に、誘導加熱調理器２の各構成について、順に説明する。 Hereinafter, each component of the induction heating cooker 2 will be described in order.
　なお、以下では、図中に示すように、誘導加熱調理器２における幅方向をＸ方向、奥行方向をＹ方向、高さ方向をＺ方向として、説明する。 In addition, below, as shown in the figure, the width direction in the induction heating cooker 2 will be described as the X direction, the depth direction as the Y direction, and the height direction as the Z direction.
　被加熱物４は、誘導加熱調理器２により誘導加熱される、例えば調理用鍋などの対象物から構成される。被加熱物４は、少なくとも一部が金属で形成される。これにより、コイル１０が発生させる磁力線により金属に渦電流が流れて、被加熱物４の誘導加熱が可能となる。 The object to be heated 4 is composed of an object such as a cooking pan that is induction-heated by the induction heating cooker 2. At least a part of the article to be heated 4 is made of metal. Thereby, an eddy current flows in the metal by the magnetic force lines generated by the coil 10, and the induction heating of the article to be heated 4 becomes possible.
　本体部６は、ユーザが、誘導加熱調理器２による調理を行う土台部分を構成する。本体部６は、上部に、トッププレート８が配設される。トッププレート８は、透光性を有する、例えば結晶化ガラスなどで形成され、誘導加熱調理器２の天板を構成する。トッププレート８の上部には、被加熱物４および非接触受電装置１１などが載置される。 The main body 6 constitutes a base part where the user cooks with the induction heating cooker 2. The main body 6 is provided with a top plate 8 at the top. The top plate 8 is formed of, for example, crystallized glass having translucency, and constitutes the top plate of the induction heating cooker 2. An object to be heated 4 and a non-contact power receiving device 11 are placed on the top of the top plate 8.
　コイル１０は、磁力線を発生して、被加熱物４の誘導加熱や非接触受電装置１１への給電または充電などを行う。なお、本実施の形態のコイル１０は、図２に示すように、上方視において、中央部分が空洞のドーナツ型の形状で構成される。コイル１０の周囲には、後述する発光ユニット１６が配置される。 The coil 10 generates lines of magnetic force to perform induction heating of the object to be heated 4, power supply to the non-contact power receiving device 11, or charging. In addition, as shown in FIG. 2, the coil 10 of this Embodiment is comprised by the doughnut-shaped shape where a center part is hollow in upper direction. Around the coil 10, a light emitting unit 16 to be described later is disposed.
　また、コイル１０は、図２に示すように、複数の縦列（Ｙ方向）および複数の横列（Ｘ方向）で構成される格子状（ＸＹ平面）に配置される。この配置により、被加熱物４または非接触受電装置１１をトッププレート８上の任意の位置に載置しても、少なくとも被加熱物４、または非接触受電装置１１の直下に配置される１つのコイル１０により誘導加熱、または給電・充電が可能となる。 Further, as shown in FIG. 2, the coils 10 are arranged in a lattice shape (XY plane) composed of a plurality of columns (Y direction) and a plurality of rows (X direction). With this arrangement, even when the object to be heated 4 or the non-contact power receiving device 11 is placed at an arbitrary position on the top plate 8, at least one object to be disposed immediately below the object to be heated 4 or the non-contact power receiving device 11. The coil 10 enables induction heating or power feeding / charging.
　なお、非接触受電装置１１は、トッププレート８上に載置されたときに、トッププレート８の直下に配置される、少なくとも１つのコイル１０により給電・充電が可能な、例えばタブレットなどの装置から構成される。 The non-contact power receiving device 11 is placed on the top plate 8 and can be supplied and charged by at least one coil 10 disposed immediately below the top plate 8, for example, from a device such as a tablet. Composed.
　そのため、非接触受電装置１１は、内部に、通信部１１ａと、受電コイル１１ｂなどを備える。通信部１１ａは、後述する本体部６内の制御部１８と通信する。 Therefore, the non-contact power receiving device 11 includes a communication unit 11a, a power receiving coil 11b, and the like inside. The communication part 11a communicates with the control part 18 in the main-body part 6 mentioned later.
　受電コイル１１ｂは、非接触受電装置１１がトッププレート８上に載置されたときに、載置された直下におけるコイル１０（例えば、１次コイルに相当）が発生した電磁界を受けて電力を発生させる、例えば２次コイルを構成する。これにより、非接触受電装置１１は、コイル１０で発生する電磁界を、受電コイル１１ｂを介して、給電可能に構成される。 When the non-contact power receiving device 11 is placed on the top plate 8, the power receiving coil 11b receives the electromagnetic field generated by the coil 10 (for example, corresponding to the primary coil) immediately below the power receiving coil 11b. For example, a secondary coil is generated. Thereby, the non-contact power receiving apparatus 11 is configured to be able to supply the electromagnetic field generated by the coil 10 via the power receiving coil 11b.
　なお、非接触受電装置１１は、例えば湯沸かし器やグリルなどのヒータを備えた電気機器、ミキサーなどのモータを備えた電気機器、照明器具やアイロンなどの非接触で電力を受電する受電装置などが例示される。この場合、ミキサーは、例えばミキサーの容器内に配置した食品を自動で撹拌するとともに、容器の誘導加熱で加熱調理を行う構成を備える。 Examples of the non-contact power receiving device 11 include an electric device having a heater such as a water heater and a grill, an electric device having a motor such as a mixer, and a power receiving device that receives power in a non-contact manner such as a lighting fixture and an iron. Is done. In this case, the mixer includes, for example, a configuration in which food placed in a container of the mixer is automatically stirred and cooked by induction heating of the container.
　以下では、本実施の形態の非接触受電装置１１として、グリラーを例に説明する。グリラーは、受電コイル１１ｂを介して、給電される電力で駆動されるヒータにより、庫内に配置した食品を加熱調理する装置である。 Hereinafter, as a non-contact power receiving apparatus 11 according to the present embodiment, a description will be given by taking a killer as an example. The griller is a device that heats and cooks food disposed in the cabinet with a heater that is driven by power supplied through the power receiving coil 11b.
　さらに、図２に示すように、非接触受電装置１１は、平面視における大きさが、コイル１０の４つ分（縦横に２列ずつ）に相当する大きさに有する場合を、例に説明する。 Furthermore, as shown in FIG. 2, the non-contact power receiving device 11 will be described by taking as an example a case where the size in plan view has a size corresponding to four of the coils 10 (two rows vertically and horizontally). .
　また、本実施の形態の誘導加熱調理器２は、備え付け表示部１２を備える。備え付け表示部１２は、例えば液晶ディスプレイなどで構成され、例えば誘導加熱調理器２の調理に関する情報（調理情報）を表示する。備え付け表示部１２は、図１に示すように、本体部６の前面（Ｙ方向手前側）に固定して設けられる。なお、備え付け表示部１２の設置位置は、上記本体部６の前面に限られず、それ以外の、例えば本体部６の上面などに設けてもよい。 Moreover, the induction heating cooker 2 of the present embodiment includes an installation display unit 12. The equipped display unit 12 is configured by a liquid crystal display, for example, and displays information (cooking information) related to cooking by the induction heating cooker 2, for example. As shown in FIG. 1, the installation display unit 12 is fixedly provided on the front surface (the front side in the Y direction) of the main body unit 6. In addition, the installation position of the equipped display unit 12 is not limited to the front surface of the main body unit 6, and may be provided, for example, on the upper surface of the main body unit 6.
　温度検知部１４は、例えばサーミスタなどの温度センサで構成され、コイル１０の上方におけるトッププレート８の温度を検知する。本実施の形態では、温度検知部１４は、それぞれのコイル１０に対応して１つずつ設けられる。なお、図１では、温度検知部１４をトッププレート８の下面に接触して設ける構成を例に示しているが、これに限られない。トッププレート８の温度を検知できる位置であれば、例えばコイル１０の周辺などに温度検知部１４を配置してもよい。 The temperature detection unit 14 is configured by a temperature sensor such as a thermistor, for example, and detects the temperature of the top plate 8 above the coil 10. In the present embodiment, one temperature detection unit 14 is provided corresponding to each coil 10. In addition, in FIG. 1, although the structure which provides the temperature detection part 14 in contact with the lower surface of the top plate 8 is shown as an example, it is not restricted to this. As long as the temperature of the top plate 8 can be detected, the temperature detector 14 may be disposed around the coil 10, for example.
　発光ユニット１６は、図２に示すように、それぞれのコイル１０の周囲に、個別に配置される。発光ユニット１６は、発光により、電磁界を発生しているコイル１０の位置を、ユーザが、トッププレート８を通して目視可能（視認可能）にする。なお、本実施の形態における発光ユニット１６は、コイル１０を囲むように設けられた、例えばリング状のＬＥＤで構成される。発光ユニット１６は、後述するように、非接触受電装置１１の載置可能領域を案内する案内部として、機能する。 The light emitting units 16 are individually arranged around each coil 10 as shown in FIG. The light emitting unit 16 makes the position of the coil 10 generating the electromagnetic field visible by the light emission through the top plate 8 (visible). In addition, the light emitting unit 16 in this Embodiment is comprised, for example with ring-shaped LED provided so that the coil 10 might be enclosed. As will be described later, the light emitting unit 16 functions as a guide unit that guides the mountable area of the non-contact power receiving device 11.
　制御部１８は、本体部６内に配置され、誘導加熱調理器２の運転を制御する。具体的には、制御部１８は、本体部６内に配置された複数のコイル１０、備え付け表示部１２および複数の温度検知部１４に接続され、これらの運転を制御する。 The control unit 18 is disposed in the main body unit 6 and controls the operation of the induction heating cooker 2. Specifically, the control unit 18 is connected to the plurality of coils 10, the equipped display unit 12, and the plurality of temperature detection units 14 arranged in the main body unit 6, and controls these operations.
　さらに、制御部１８は、非接触受電装置１１の通信部１１ａと無線通信が可能に構成される。これにより、制御部１８は、通信部１１ａから、例えば受電電力や緊急停止などの信号を受信する。 Furthermore, the control unit 18 is configured to be able to perform wireless communication with the communication unit 11a of the non-contact power receiving apparatus 11. Thereby, the control part 18 receives signals, such as received electric power and an emergency stop, from the communication part 11a, for example.
　上記構成を有する誘導加熱調理器２は、トッププレート８上の任意の位置に被加熱物４や非接触受電装置１１を載置可能なレイアウト自由のマルチコイル構成を採用している。これにより、ユーザは、トッププレート８上の所望の位置に被加熱物４および非接触受電装置１１を載置できる。そのため、ユーザに対する自由度の高い構成が可能となる。 The induction heating cooker 2 having the above configuration employs a layout-free multi-coil configuration in which the heated object 4 and the non-contact power receiving device 11 can be placed at an arbitrary position on the top plate 8. Thereby, the user can place the article to be heated 4 and the non-contact power receiving device 11 at a desired position on the top plate 8. Therefore, a configuration with a high degree of freedom for the user is possible.
　以上のように、本実施の形態の誘導加熱調理器２が構成される。 As described above, the induction heating cooker 2 of the present embodiment is configured.
　以下に、トッププレート８上において非接触受電装置１１の載置可能な領域を、温度検知部１４および発光ユニット１６を用いて、ユーザに案内する方法について、図３および図４Ａから図４Ｄを用いて説明する。 Hereinafter, a method of guiding the user to the area where the non-contact power receiving device 11 can be placed on the top plate 8 using the temperature detection unit 14 and the light emitting unit 16 will be described with reference to FIGS. 3 and 4A to 4D. I will explain.
　図３は、誘導加熱調理器におけるディスプレイの載置可能領域を表示する方法を示すフローチャートである。図４Ａから図４Ｄは、図３に示すフローチャートに沿って、順に載置可能領域を表示し案内する一例を説明する平面図である。 FIG. 3 is a flowchart showing a method of displaying the displayable area of the display in the induction heating cooker. 4A to 4D are plan views for explaining an example of displaying and guiding the mountable areas in order according to the flowchart shown in FIG.
　図３に示すように、まず、非接触受電装置１１から、本体部６の制御部１８に信号を送信する（ステップＳ１）。具体的には、ユーザが非接触受電装置１１に設けられたボタン（図示せず）を押下する。これにより、非接触受電装置１１の通信部１１ａは、制御部１８に信号を送信する。 As shown in FIG. 3, first, a signal is transmitted from the non-contact power receiving device 11 to the control unit 18 of the main body 6 (step S1). Specifically, the user presses a button (not shown) provided on the non-contact power receiving apparatus 11. Thereby, the communication unit 11 a of the non-contact power receiving apparatus 11 transmits a signal to the control unit 18.
　制御部１８は、通信部１１ａからの信号により、トッププレート８上に非接触受電装置１１が載置されることを認識する。このとき、制御部１８は、非接触受電装置１１に関する各種情報（例えば、非接触受電装置１１の種類やサイズの情報など）を記憶している。そこで、制御部１８は、非接触受電装置１１から送信された信号を受信すると、非接触受電装置１１に関する情報を読み出す。 The control unit 18 recognizes that the non-contact power receiving device 11 is placed on the top plate 8 by a signal from the communication unit 11a. At this time, the control unit 18 stores various information related to the non-contact power receiving apparatus 11 (for example, information on the type and size of the non-contact power receiving apparatus 11). Therefore, when the control unit 18 receives a signal transmitted from the non-contact power receiving device 11, the control unit 18 reads information on the non-contact power receiving device 11.
　つぎに、制御部１８は、コイル１０による加熱状況を確認する（ステップＳ２）。つまり、制御部１８は、複数のコイル１０のそれぞれについて、加熱中であるか否かを確認する。本実施の形態では、図４Ａに示すように、例えば１つのコイル１０ａが加熱中であることが確認される。これにより、コイル１０ａの上方に位置するトッププレート８の上面に誘導加熱を受ける被加熱物４（図示せず）が載置されていることを確認できる。 Next, the control unit 18 confirms the heating status by the coil 10 (step S2). That is, the control unit 18 confirms whether or not each of the plurality of coils 10 is being heated. In the present embodiment, as shown in FIG. 4A, for example, it is confirmed that one coil 10a is being heated. Thereby, it can confirm that the to-be-heated material 4 (not shown) which receives induction heating is mounted in the upper surface of the top plate 8 located above the coil 10a.
　つぎに、制御部１８は、温度検知部１４から入力される、それぞれのコイル１０の温度判定を行う（ステップＳ３）。具体的には、ステップＳ２で加熱中と確認されたコイル１０ａおよびその周囲領域を除いて、制御部１８は、それ以外のコイル１０の温度検知部１４で検知された温度が所定温度（例えば、６０℃）以上であるか否かを判定する。このとき、ステップＳ２で加熱中と確認されたコイル１０ａおよびその周囲領域は、図４Ｂに示す領域Ａ１が相当する。そこで、制御部１８は、領域Ａ１を除くトッププレート８上の領域において、温度検知部１４で検知された温度が所定温度以上であるか否かを判定する。 Next, the control unit 18 determines the temperature of each coil 10 input from the temperature detection unit 14 (step S3). Specifically, except for the coil 10a that has been confirmed to be heated in step S2 and its surrounding area, the controller 18 detects that the temperature detected by the temperature detectors 14 of the other coils 10 is a predetermined temperature (for example, 60 ° C.) or higher. At this time, the coil 10a confirmed to be heated in step S2 and its surrounding area correspond to the area A1 shown in FIG. 4B. Therefore, the control unit 18 determines whether or not the temperature detected by the temperature detection unit 14 is equal to or higher than a predetermined temperature in the region on the top plate 8 excluding the region A1.
　そして、温度判定の結果、図４Ｃに示すように、例えば複数のコイル１０のうち、領域Ａ１に隣接する３つのコイル１０ｂ、コイル１０ｃ、コイル１０ｄに対応する領域Ａ２において、制御部１８は、温度検知部１４で検知した温度が所定温度以上であると判定する。 As a result of the temperature determination, as shown in FIG. 4C, for example, in the region A2 corresponding to the three coils 10b, 10c, and 10d adjacent to the region A1 among the plurality of coils 10, the control unit 18 It determines with the temperature detected by the detection part 14 being more than predetermined temperature.
　つぎに、制御部１８は、発光ユニット１６による発光表示を行う（ステップＳ４）。具体的には、図４Ｄに示すように、制御部１８は、領域Ａ１と、ステップＳ３で所定温度以上と判定した領域Ａ２を除く所定の領域Ａ３において、発光ユニット１６による発光を行う。つまり、制御部１８は、温度の高い領域（例えば、領域Ａ１および領域Ａ２）を除外した温度の低い領域Ａ３を発光させる。これにより、制御部１８は、非接触受電装置１１を載置するのに好ましい領域として、領域Ａ３を発光表示して、ユーザを案内する。 Next, the control unit 18 performs light emission display by the light emitting unit 16 (step S4). Specifically, as illustrated in FIG. 4D, the control unit 18 performs light emission by the light emitting unit 16 in the area A1 and the predetermined area A3 excluding the area A2 determined to be equal to or higher than the predetermined temperature in step S3. That is, the control unit 18 causes the low temperature region A3 to emit light excluding the high temperature regions (for example, the region A1 and the region A2). As a result, the control unit 18 emits and displays the area A3 as a preferable area for placing the non-contact power receiving device 11 to guide the user.
　このとき、制御部１８は、図４Ｄに示す領域Ａ２に隣接する領域Ａ４（Ｙ方向手前側の領域）を、ステップＳ３で所定温度以上であるとは判定していない。それにも関わらず、制御部１８は、以下に示す理由により、ステップＳ４で発光ユニット１６を発光させるように制御しない。 At this time, the control unit 18 does not determine that the region A4 (region on the front side in the Y direction) adjacent to the region A2 illustrated in FIG. 4D is equal to or higher than the predetermined temperature in step S3. Nevertheless, the control unit 18 does not control the light emitting unit 16 to emit light in step S4 for the following reason.
　なぜならば、非接触受電装置１１のサイズは、上述したように、縦横に２列ずつ合計４つ分の範囲のコイル１０の領域に相当する。つまり、領域Ａ４は、非接触受電装置１１を載置する、４つ分の大きさの領域を確保できない。そのため、制御部１８は、領域Ａ４を非接触受電装置１１の載置可能領域から除外して、発光ユニット１６が発光しないように制御する。これにより、制御部１８は、領域Ａ３の発光ユニット１６のみを、非接触受電装置１１の載置可能な領域として発光させる。その結果、非接触受電装置１１の載置可能な領域を、ユーザに対して、より確実に案内できる。 This is because, as described above, the size of the non-contact power receiving device 11 corresponds to the area of the coil 10 in a range of a total of four by two rows in the vertical and horizontal directions. That is, the area A4 cannot secure an area of four sizes on which the non-contact power receiving device 11 is placed. Therefore, the control unit 18 excludes the area A4 from the mountable area of the non-contact power receiving apparatus 11 and performs control so that the light emitting unit 16 does not emit light. Thereby, the control unit 18 causes only the light emitting unit 16 in the area A3 to emit light as an area where the non-contact power receiving device 11 can be placed. As a result, the area where the non-contact power receiving device 11 can be placed can be more reliably guided to the user.
　以上により、トッププレート８の非接触受電装置１１の載置可能な領域が、発光ユニット１６の発光により、表示される。 As described above, the area where the non-contact power receiving device 11 of the top plate 8 can be placed is displayed by the light emission of the light emitting unit 16.
　つまり、本実施の形態によれば、制御部１８は、非接触受電装置１１の載置可能な領域として、温度の低い領域Ａ３の発光ユニット１６を発光させて表示し、ユーザを案内する。これにより、ユーザは、発光する温度の低い安全な領域Ａ３に、非接触受電装置１１を載置することができる。そのため、温度の高い領域への非接触受電装置１１の載置を未然に防止できる。これにより、非接触受電装置１１自体の故障や、温度の高い領域へのユーザの接触による不具合の発生を防止する。その結果、利便性および安全性を、より向上させることができる。 That is, according to the present embodiment, the control unit 18 causes the light-emitting unit 16 in the low-temperature region A3 to emit light and display it as a region where the non-contact power receiving device 11 can be placed, and guides the user. Thereby, the user can place the non-contact power receiving device 11 in the safe area A3 where the temperature of light emission is low. Therefore, it is possible to prevent the contactless power receiving device 11 from being placed in a high temperature region. Thereby, the failure of the non-contact power receiving apparatus 11 itself and the occurrence of problems due to the user's contact with a high temperature region are prevented. As a result, convenience and safety can be further improved.
　また、本実施の形態によれば、トッププレート８上の任意の位置に被加熱物４や非接触受電装置１１を載置可能なマルチコイル構成を採用している。そして、この構成において、温度の低い安全な領域を、載置可能な領域として表示する。これにより、被加熱物４や非接触受電装置１１を温度の低い安全な領域に、確実に載置できる。つまり、本実施の形態の誘導加熱調理器２は、非接触受電装置１１を載置可能な領域に案内するなどの有用性の点で優れている。 In addition, according to the present embodiment, a multi-coil configuration in which the heated object 4 and the non-contact power receiving device 11 can be placed at an arbitrary position on the top plate 8 is adopted. And in this structure, the safe area | region with low temperature is displayed as an area | region which can be mounted. Thereby, the to-be-heated material 4 and the non-contact power receiving apparatus 11 can be reliably mounted in the safe area | region where temperature is low. That is, the induction heating cooker 2 according to the present embodiment is excellent in terms of usefulness such as guiding the non-contact power receiving device 11 to a region where the non-contact power receiving device 11 can be placed.
　また、本実施の形態によれば、制御部１８は、非接触受電装置１１の通信部１１ａの信号を受信してから、発光ユニット１６による表示案内を実行する。そのため、例えばユーザが非接触受電装置１１のボタンを押下することで信号の送信を行う構成を採用している。これにより、ユーザは、発光ユニット１６による表示案内を、所望のタイミングで行うことが可能となる。その結果、ユーザへの利便性が、さらに向上する。 Moreover, according to this Embodiment, the control part 18 performs the display guidance by the light emission unit 16, after receiving the signal of the communication part 11a of the non-contact electric power receiving apparatus 11. FIG. Therefore, for example, a configuration is employed in which a signal is transmitted by the user pressing a button on the non-contact power receiving apparatus 11. Thereby, the user can perform display guidance by the light emitting unit 16 at a desired timing. As a result, the convenience for the user is further improved.
　また、本実施の形態によれば、制御部１８は、非接触受電装置１１のサイズの情報を記憶している。そして、制御部１８は、記憶したサイズの情報に基づいて、非接触受電装置１１の載置可能な領域のみを、発光ユニット１６により表示する。これにより、非接触受電装置１１の載置可能な領域を、より確実に、ユーザに案内できる。その結果、ユーザの利便性を、さらに向上させることができる。 Further, according to the present embodiment, the control unit 18 stores information on the size of the non-contact power receiving device 11. And the control part 18 displays only the area | region which can mount the non-contact power receiving apparatus 11 by the light emission unit 16 based on the memorize | stored size information. Thereby, the area | region which can mount the non-contact power receiving apparatus 11 can be more reliably guided to a user. As a result, user convenience can be further improved.
　また、本実施の形態によれば、制御部１８は、加熱中であるコイル１０ａの周囲（例えば、領域Ａ１、Ａ２）、および非接触受電装置１１の載置不可能な領域Ａ４を発光させないように、発光ユニット１６の発光を制御する。これにより、加熱中のコイル１０ａの周囲の領域で、かつ温度が低い領域の場合でも、制御部１８は、非接触受電装置１１の載置可能な領域として、案内しない。 Further, according to the present embodiment, the control unit 18 does not emit light around the coil 10a being heated (for example, the regions A1 and A2) and the region A4 where the non-contact power receiving device 11 cannot be placed. In addition, the light emission of the light emitting unit 16 is controlled. Thereby, even in the region around the coil 10a being heated and in the region where the temperature is low, the control unit 18 does not guide as a region where the non-contact power receiving device 11 can be placed.
　つまり、コイル１０ａによる被加熱物４の加熱調理による周囲への、以下に示す影響を低減できる。 That is, it is possible to reduce the following effects on the surroundings due to cooking of the article 4 to be heated by the coil 10a.
　具体的には、例えばコイル１０ａで加熱されている被加熱物４が水分を含む場合、高温となった水滴が、コイル１０ａの周囲に飛散する場合がある。飛散した水滴は、非接触受電装置１１やユーザに付着する場合がある。これにより、非接触受電装置１１の故障の原因や、ユーザへの不具合を生じる虞がある。そこで、本実施の形態では、加熱中であるコイル１０ａの周囲を載置可能な領域から除外して、発光ユニット１６を発光しないように制御する。これにより、ユーザへの利便性、および誘導加熱調理器２の安全性を、さらに向上させることができる。 Specifically, for example, when the object to be heated 4 heated by the coil 10a contains moisture, water droplets having a high temperature may be scattered around the coil 10a. The scattered water droplets may adhere to the non-contact power receiving device 11 or the user. Thereby, there is a possibility that the cause of the failure of the non-contact power receiving device 11 or a problem to the user may occur. Therefore, in the present embodiment, the periphery of the coil 10a being heated is excluded from the mountable region, and the light emitting unit 16 is controlled not to emit light. Thereby, the convenience to a user and the safety | security of the induction heating cooking appliance 2 can be improved further.
　また、本実施の形態によれば、温度検知部１４として、それぞれのコイル１０に対応して複数の温度センサを設ける。これにより、それぞれのコイル１０の領域に対応した温度の検知が可能となる。その結果、検知した温度に基づいて、非接触受電装置１１の載置可能な領域を、より精度良く設定できる。 In addition, according to the present embodiment, a plurality of temperature sensors are provided corresponding to each coil 10 as the temperature detection unit 14. Thereby, the temperature corresponding to the area of each coil 10 can be detected. As a result, the region where the non-contact power receiving device 11 can be placed can be set with higher accuracy based on the detected temperature.
　また、本実施の形態によれば、非接触受電装置１１の載置可能な領域の、ユーザへの案内を、発光ユニット１６の発光の有無により行う。つまり、発光ユニット１６を、案内部として機能させる。これにより、ユーザは、非接触受電装置１１の載置可能な領域を、視覚的に判断できる。その結果、ユーザへの利便性が、さらに向上する。 Further, according to the present embodiment, guidance to the user of the area where the non-contact power receiving device 11 can be placed is performed based on whether or not the light emitting unit 16 emits light. That is, the light emitting unit 16 is caused to function as a guide unit. Thereby, the user can visually determine the area where the non-contact power receiving apparatus 11 can be placed. As a result, the convenience for the user is further improved.
　なお、上記では、実施の形態を挙げて本開示を説明したが、本開示は上述の実施の形態に限定されない。 In the above description, the present disclosure has been described with reference to the embodiment. However, the present disclosure is not limited to the above-described embodiment.
　つまり、本実施の形態では、発光ユニット１６をコイル１０の周囲を囲むようにリング状のＬＥＤを設ける構成を例に説明したが、これに限られない。非接触受電装置１１などの載置可能な領域を示すように発光する発光ユニットであれば、発光ユニットの構成は任意でよい。例えば、コイルの１つ分の領域を１単位（１グリッド）として、グリッド状（格子状）に発光する発光ユニットで構成でもよい。 That is, in the present embodiment, the configuration in which the light emitting unit 16 is provided with the ring-shaped LED so as to surround the coil 10 is described as an example, but the present invention is not limited thereto. The configuration of the light emitting unit may be arbitrary as long as it is a light emitting unit that emits light so as to indicate a mountable region such as the non-contact power receiving device 11. For example, the area for one coil may be one unit (one grid), and the light emitting unit may emit light in a grid shape (lattice shape).
　また、本実施の形態では、複数のコイル１０をＹ方向に沿って複数の縦列、Ｘ方向に沿って複数の横列で格子状に配置する構成を例に説明したが、これに限られない。例えば、図５の変形例に示すように、複数のコイル２０を互い違い（千鳥状）に配置し、Ｘ方向およびＹ方向とは異なる、例えば斜め方向に配置してもよい。この場合、上述の実施の形態と同様に、コイル２０のそれぞれの周りに発光ユニット２６を配置してもよい。これにより、それぞれのコイル１０の間が狭まるため、調理を行う際の加熱分布が、より均一化される。さらに、電力送電時において、同一面積で、より多くの電力を送ることができる。 In the present embodiment, the configuration in which the plurality of coils 10 are arranged in a lattice pattern in a plurality of columns along the Y direction and a plurality of rows along the X direction has been described as an example. However, the present invention is not limited thereto. For example, as shown in the modification of FIG. 5, the plurality of coils 20 may be arranged alternately (staggered), and may be arranged in an oblique direction different from the X direction and the Y direction, for example. In this case, the light emitting unit 26 may be disposed around each of the coils 20 as in the above-described embodiment. Thereby, since each coil 10 narrows, the heating distribution at the time of cooking is made more uniform. Furthermore, more power can be sent in the same area during power transmission.
　さらに、それぞれのコイル２０の周りに発光ユニット２６を配置せずに、以下に示す別の方法で、非接触受電装置１１の載置可能な領域を表示して案内する構成としてもよい。具体的には、例えば備え付け表示部１２に載置可能な領域を表示して案内する構成としてもよい。また、誘導加熱調理器２と通信する外部ディスプレイに載置可能な領域を表示して案内する構成としてもよい。つまり、備え付け表示部１２や外部ディスプレイを載置可能な領域の案内部として機能させてもよい。さらに、これらの案内部を併用して機能させてもよい。これにより、誘導加熱調理器２の仕様やユーザの好みに応じて、誘導加熱調理器２の設置場所や載置可能な領域を適宜設定できる。その結果、ユーザへの利便性を、さらに向上できる。 Furthermore, the light-emitting unit 26 may not be disposed around each coil 20, and a region where the non-contact power receiving device 11 can be placed may be displayed and guided by another method described below. Specifically, for example, an area that can be placed on the equipped display unit 12 may be displayed and guided. Moreover, it is good also as a structure which displays and guides the area | region which can be mounted in the external display communicated with the induction heating cooking appliance 2. FIG. That is, you may make it function as a guide part of the area | region which can mount the installation display part 12 and an external display. Furthermore, these guide parts may be used in combination. Thereby, according to the specification of the induction heating cooking appliance 2, and a user's liking, the installation place of the induction heating cooking appliance 2 and the area | region which can be mounted can be set suitably. As a result, the convenience for the user can be further improved.
　また、本実施の形態では、発光ユニット１６、２６などにより視覚的に表示して案内する構成を例に説明したが、これに限られない。例えば、音声案内部などを設けて、ユーザに、音声で載置可能な領域を案内する構成としてもよい。これにより、例えば視覚に障害を持つ使用者でも、簡便に使用することができる。 Further, in the present embodiment, the configuration in which the light emitting units 16 and 26 visually display and guide is described as an example, but the present invention is not limited to this. For example, it is good also as a structure which provides an audio | voice guidance part etc. and guides the area | region which can be mounted with an audio | voice to a user. Accordingly, for example, even a user who has a visual impairment can be used easily.
　また、本実施の形態では、トッププレート８上の任意の位置に、被加熱物４や非接触受電装置１１を、載置可能でレイアウト自由のマルチコイル構成を例に説明したが、これに限られない。例えば、被加熱物４や非接触受電装置１１の載置場所（加熱領域）を予め複数箇所に定める。予め設定したそれぞれの載置場所に対応して、コイルを設ける。そして、複数の載置場所の中から、ユーザが任意の位置に被加熱物４や非接触受電装置１１を載置する構成としてもよい。このとき、各載置場所の領域に対応して設けられた液晶やＬＥＤのセグメント表示などで構成された操作部を点灯させ、非接触受電装置１１の載置可能な領域を案内する構成としてもよい。これにより、コイル２０の数が少なくなるので、誘導加熱調理器２全体の低コスト化が図れる。さらに、ユーザは、非接触受電装置の載置場所を、より判別しやすくなる。 In the present embodiment, the heated object 4 and the non-contact power receiving device 11 can be placed at an arbitrary position on the top plate 8 as an example of a multi-coil configuration in which layout is free. However, the present invention is not limited to this. I can't. For example, the placement location (heating region) of the object to be heated 4 and the non-contact power receiving device 11 is determined in advance at a plurality of locations. A coil is provided corresponding to each preset placement location. And it is good also as a structure which a user mounts the to-be-heated material 4 and the non-contact power receiving apparatus 11 in arbitrary positions from several mounting places. At this time, it is also possible to turn on the operation unit configured by liquid crystal or LED segment display provided corresponding to the area of each placement place and guide the area where the non-contact power receiving device 11 can be placed. Good. Thereby, since the number of the coils 20 decreases, the cost reduction of the induction heating cooking appliance 2 whole can be achieved. Furthermore, the user can more easily determine the placement location of the non-contact power receiving apparatus.
　また、本実施の形態では、図３のフローチャートの例示において、ステップＳ２で非接触受電装置１１を載置する前に、１つのコイル１０ａが加熱中である場合を例に説明した。つまり、トッププレート８上に既に被加熱物４が置かれている場合を例に説明したが、これに限られない。例えば、加熱中のコイル１０が存在しない、すなわちトッププレート８上に被加熱物４が置かれていない状態の場合でもよい。この場合、まず、図３に示すステップＳ３の温度判定において、制御部１８は、全ての領域における温度検知部１４の温度結果を判定する。そして、制御部１８は、判定結果に基づいて、ステップＳ４による、発光ユニット１６の発光制御を行えばよい。この場合、発光ユニットの発光制御による載置案内に基づいて、ユーザは、トッププレート８上に非接触受電装置１１を載置する。そして、その後、被加熱物４をトッププレート８上に載置して、加熱制御を行う構成としてもよい。これにより、例えば加熱後の高温のフライパンや、オーブンなどの他の調理機器で調理した後の鍋や調理物などを、トッププレート８上に置いている場合でも、ディスプレイを低温の領域に載置して、安全に使用できる。 In the present embodiment, in the example of the flowchart of FIG. 3, the case where one coil 10a is being heated before placing the non-contact power receiving device 11 in step S2 has been described as an example. That is, although the case where the to-be-heated material 4 has already been put on the top plate 8 was demonstrated to the example, it is not restricted to this. For example, there may be a case where the coil 10 being heated does not exist, that is, the heated object 4 is not placed on the top plate 8. In this case, first, in the temperature determination in step S3 shown in FIG. 3, the control unit 18 determines the temperature result of the temperature detection unit 14 in all regions. And the control part 18 should just perform the light emission control of the light emission unit 16 by step S4 based on a determination result. In this case, the user places the non-contact power receiving device 11 on the top plate 8 based on the placement guidance by the light emission control of the light emitting unit. And after that, it is good also as a structure which mounts the to-be-heated material 4 on the top plate 8, and performs heating control. Thereby, for example, even when a hot pan after cooking or a pan or cooked food after cooking with another cooking device such as an oven is placed on the top plate 8, the display is placed in a low temperature region. And can be used safely.
　また、本実施の形態では、トッププレート８上に１つの被加熱物４を配置する場合を例に説明したが、これに限られない。例えば、トッププレート８上に複数の被加熱物４を配置してもよい。この場合でも、図３のステップＳ３で説明した制御と、同様の制御を個別に行えばよい。 In the present embodiment, the case where one object to be heated 4 is arranged on the top plate 8 has been described as an example, but the present invention is not limited to this. For example, a plurality of objects to be heated 4 may be disposed on the top plate 8. Even in this case, the control similar to the control described in step S3 in FIG. 3 may be performed individually.
　また、本実施の形態では、図３に示すステップＳ２で、コイル１０ａが加熱中であると判断された領域およびその周囲領域を除いて、ステップＳ３の温度判定を行う場合を例に説明したが、これに限られない。例えば、図３のステップＳ２で、コイル１０ａが加熱中であると判断された領域のみを除いて、すなわちコイル１０ａの周囲領域を含む領域でステップＳ３の温度判定を行ってもよい。このとき、「周囲領域」は、図４Ｂなどに示す範囲の広さに限られず、任意の広さの領域でよい。これにより、コイル１０ａでの加熱電力が低く、それほど温度が高くない場合において、非接触受電装置を安全に載置できる場所を、より広く取ることができる。 Further, in the present embodiment, the case has been described as an example in which the temperature determination in step S3 is performed except for the region where the coil 10a is determined to be heated and its surrounding region in step S2 shown in FIG. Not limited to this. For example, the temperature determination of step S3 may be performed in the region including the peripheral region of the coil 10a except for the region where it is determined in step S2 of FIG. 3 that the coil 10a is being heated. At this time, the “peripheral region” is not limited to the size of the range shown in FIG. Thereby, when the heating electric power in the coil 10a is low and the temperature is not so high, a place where the non-contact power receiving device can be safely placed can be taken wider.
　また、本実施の形態では、図３のステップＳ１において、ユーザの非接触受電装置１１のボタンの押下操作により、制御部１８に信号を送信する場合を例に説明したが、これに限られない。例えば、誘導加熱調理器２の本体部６などに設けたボタンの押下操作により、図３のステップＳ２からステップＳ４のみを実施して、発光ユニットの発光を制御してもよい。これにより、図３に示すフローチャートのステップＳ１を省略できる。 Moreover, although this Embodiment demonstrated as an example the case where a signal is transmitted to the control part 18 by step-down operation of the button of the non-contact power receiving apparatus 11 of a user in FIG.3, it is not restricted to this. . For example, only the steps S2 to S4 in FIG. 3 may be performed by pressing a button provided on the main body 6 of the induction heating cooker 2 to control the light emission of the light emitting unit. Thereby, step S1 of the flowchart shown in FIG. 3 can be omitted.
　さらに、ボタンの押下操作ではなく、非接触受電装置１１が本体部６に近付いたときに、非接触受電装置１１の通信部１１ａが、本体部６の制御部１８へ自動的に信号を送信する構成としてもよい。これにより、使用者の操作が少なく、より簡便に使用できる。 Further, when the non-contact power receiving device 11 approaches the main body 6 instead of pressing the button, the communication unit 11a of the non-contact power receiving device 11 automatically transmits a signal to the control unit 18 of the main body 6. It is good also as a structure. Thereby, there are few operations of a user and it can be used more simply.
