Description

この発明は誘導加熱調理器、特に、その内部に配置される構成部材の冷却構造に特徴を有す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, and more particularly to an induction heating cooker characterized by a cooling structure for components disposed therein.

従来の誘導加熱調理器は、調理器本体の上部に鍋などの調理容器が置載される天板と、天板下に配置される複数の誘導加熱コイルと誘導加熱コイルに高周波電流を流すインバータ回路と、他にロースターが配置されている。これらの冷却用として、本体後方にモータで駆動されるファンが配置されている。このとき、調理器本体後方からファンによって吸気された外気は、インバータ回路を冷却し、その後誘導加熱コイルなどを冷却し、調理器外へ排気される構造となっている。
また、誘導加熱コイルの前方の天板下に、使用者の操作設定に受け付けると共に、該受け付けた操作設定の内容をインバータ回路に指示する操作回路部と、該内容を表示する表示部とが設けられるため、該操作回路部および該表示部は誘導加熱コイルからの伝熱によって加熱され受け易い構造になっている。
そのため、該操作回路部および該表示部を外気によって冷却する誘導加熱調理器が開示されている（特許文献１参照。）。 A conventional induction heating cooker has a top plate on which a cooking container such as a pan is placed at the top of the cooker body, an inverter that passes a high-frequency current through a plurality of induction heating coils and the induction heating coil arranged under the top plate. A circuit and other roasters are arranged. For these cooling purposes, a fan driven by a motor is disposed behind the main body. At this time, the outside air sucked by the fan from the rear side of the cooker body cools the inverter circuit, then cools the induction heating coil and the like, and is exhausted outside the cooker.
In addition, an operation circuit unit that accepts the user's operation settings and instructs the inverter circuit of the contents of the accepted operation settings and a display unit that displays the contents are provided below the top plate in front of the induction heating coil. Therefore, the operation circuit portion and the display portion are structured to be easily heated and received by heat transfer from the induction heating coil.
Therefore, an induction heating cooker that cools the operation circuit unit and the display unit with outside air is disclosed (see Patent Document 1).

特開２００６−２０２６２４号公報（第４−６頁、第１図）JP 2006-202624 A (page 4-6, FIG. 1)

特許文献１に開示された誘導加熱調理器は、主ファンが吸引した外気によってインバータ回路および誘導加熱コイルを冷却し、該冷却後の空気を補助ファンが吸引し、これによって操作回路部および表示部を冷却しようとするものである。すなわち、操作回路部および表示部に吹き付けられる直前の空気温度は、インバータ回路および誘導加熱コイルとの熱交換によって加熱されるため、外気の温度より高くなっている。このため、操作回路部および表示部が効率よく冷却されないという問題があった。 The induction heating cooker disclosed in Patent Document 1 cools the inverter circuit and the induction heating coil with the outside air sucked by the main fan, and the auxiliary fan sucks the cooled air, thereby the operation circuit unit and the display unit. It is something that tries to cool down. That is, the air temperature immediately before being blown to the operation circuit unit and the display unit is heated by heat exchange with the inverter circuit and the induction heating coil, and thus is higher than the temperature of the outside air. For this reason, there has been a problem that the operation circuit section and the display section are not efficiently cooled.

本発明は、上記の課題を解決するためになされたもので、インバータ回路および誘導加熱コイルと共に、本体内前方に配置される操作制御部等を効率よく冷却することができる誘導加熱調理器を得るものである。 The present invention has been made to solve the above-described problem, and an induction heating cooker capable of efficiently cooling an operation control unit and the like disposed in front of the main body together with an inverter circuit and an induction heating coil is obtained. Is.

前記操作制御部を冷却する第２冷却手段と、
上面が前記天板であって、内部に、前記誘導加熱コイル、前記加熱制御部、前記操作制御部、前記第１冷却手段、および前記第２冷却手段を収納する本体と、を有し、
前記第１冷却手段および前記第２冷却手段に外気が直接供給されることを特徴とするものである。 An induction heating cooker according to the present invention includes a top plate on which a cooking container is placed,
An induction heating coil disposed under the top plate;
A heating control unit for controlling a high-frequency current flowing through the induction heating coil;
Operation control comprising input means for inputting heating information, an operation instruction section for instructing the heating control section to input heating information to the input section, and a display section for displaying the heating information input to the input section And

The top surface is the top plate, and the body includes therein the induction heating coil, the heating control unit, the operation control unit, the first cooling unit, and the second cooling unit,
Outside air is directly supplied to the first cooling means and the second cooling means.

本発明に係る誘導加熱調理器は、第１冷却手段および第２冷却手段に外気が直接供給されるから、第１冷却手段において誘導加熱コイル及び加熱制御部は直接外気によって冷却され、同様に、第２冷却手段において操作制御部も直接外気によって冷却されるから、それぞれが効率よく冷却される。
なお、本発明において、「直接供給」または「直接冷却」とは、途中で熱交換することなく外気を供給する（供給される）こと、または未だ熱交換をしていない外気によって冷却する（冷却される）ことを意味している。したがって、共通の吸気口から吸気した外気を、熱交換する前に分岐して、それぞれを別個に冷却に供することは「直接供給」または「直接冷却」に該当するものである。
また、本発明において、「外気」とは未だ熱交換していない比較的温度の低い空気を指し、一方、「空気」とは熱交換した後の空気を指しているが、必ずしも厳格に使い分けられていない。 In the induction heating cooker according to the present invention, since the outside air is directly supplied to the first cooling means and the second cooling means, the induction heating coil and the heating control unit are directly cooled by the outside air in the first cooling means. Since the operation control unit is also directly cooled by the outside air in the second cooling means, each is efficiently cooled.
In the present invention, “direct supply” or “direct cooling” refers to supplying (supplied) outside air without heat exchange in the middle, or cooling with outside air that has not yet been heat exchanged (cooling). Is meant). Therefore, branching the outside air sucked from the common intake port before heat exchange and separately cooling the outside air corresponds to “direct supply” or “direct cooling”.
In the present invention, “outside air” refers to air of relatively low temperature that has not yet undergone heat exchange, while “air” refers to air after heat exchange, but is not necessarily strictly used. Not.

（冷却用空気の流れ）
図４および図５は、本発明の実施の形態１に係る誘導加熱調理器における冷却風の流れを模式的に説明するものであって、図４は側面視の断面図、図５の（ａ）は上面から見た下面に近い位置における断面図、図５の（ａ）は上面から見た透視図（上面に近い位置における断面図に相当する）である。なお、図示する矢印は平均とした風流れを模式的に示すものであって、実際は、流れに偏りや乱れがあるものである。また、図１〜図３と同じ部分にはこれと同じ符号を付し、一部の説明を省略する。 (Flow of cooling air)
4 and 5 schematically illustrate the flow of cooling air in the induction heating cooker according to Embodiment 1 of the present invention. FIG. 4 is a sectional view in side view, and FIG. ) Is a cross-sectional view at a position close to the bottom surface viewed from the top surface, and FIG. 5A is a perspective view (corresponding to a cross-sectional view at a position close to the top surface) viewed from the top surface. In addition, the arrow shown in figure shows the wind flow made into an average, Comprising: Actually, there exists a bias or disorder in a flow. Moreover, the same code | symbol is attached | subjected to this same part as FIGS. 1-3, and one part description is abbreviate | omitted.

図４および図５において、誘導加熱調理器１００は、操作制御部８からの指令により加熱動作が開始されると加熱制御部７を構成する回路などはスイッチング損失やその他の損失により相当の発熱をする。また、誘導加熱コイル５は加熱制御部７により高周波電流が供給され天板２の上に置載された鍋等の調理容器を誘導加熱するが、誘導加熱コイル５も、それ自身の抵抗成分等の影響により発熱する。 4 and 5, when the heating operation is started by the instruction from the operation control unit 8, the induction heating cooker 100 generates a considerable amount of heat due to switching loss and other losses in the circuits constituting the heating control unit 7. To do. The induction heating coil 5 is supplied with a high-frequency current by the heating control unit 7 and induction-heats a cooking container such as a pan placed on the top plate 2. The induction heating coil 5 also has its own resistance component and the like. It generates heat under the influence of.

（左第１冷却手段および右第１冷却手段における風流れ）
たとえば、左誘導加熱コイル５ａおよび右誘導加熱コイル５ｂの両方に通電する加熱情報が入力されると、左誘導加熱コイル５ａおよび左加熱制御部７ａと、右誘導加熱コイル５ｂおよび右加熱制御部７ｂとを冷却するために、左第１冷却手段１０ａおよび右第１冷却手段１０ｂを運転する。なお、左誘導加熱コイル５ａまたは右誘導加熱コイル５ｂの一方のみが通電されるときは、左第１ファン１２ａまたは右第１ファン１２ｂ等が起動されるものであるが、ファンの運転は左右の加熱と必ずしも連動するものではない。 (Wind flow in the left first cooling means and the right first cooling means)
For example, when heating information for energizing both the left induction heating coil 5a and the right induction heating coil 5b is input, the left induction heating coil 5a and the left heating control unit 7a, and the right induction heating coil 5b and the right heating control unit 7b. The left first cooling means 10a and the right first cooling means 10b are operated. When only one of the left induction heating coil 5a or the right induction heating coil 5b is energized, the left first fan 12a or the right first fan 12b is activated, but the fan operation is performed on the left and right sides. It is not necessarily linked with heating.

左第１冷却手段および右第１冷却手段における風流れは、側面視で略横Ｊ字状である。すなわち、本体吸気口４から流入した外気は、本体１の底面寄りに配置された第１ダクト吸引部１１において、後面に向かう風流れＷ１１を形成する。そして、第１ダクト接続部１３において流れの方向が変更され、風流れＷ１３となり、さらに、第１ダクト冷却部において前面１ｆに向かう風流れＷ１４を形成する。
そして、第１ダクト冷却部１４の終端部分（コイルベース６の下部に相当する）には、本体１の左右方向の中央側に開口する第１ダクト排気口１５が形成されているから、左第１ダクト排気口１５ａおよび右第１ダクト排気口１５ｂから本体１の内部に流出した風流れＷ１５ａ、Ｗ１５ｂは、それぞれ略中央部で衝突しながら後面に向かって流れる風流れＷ１６ａ、Ｗ１６ｂとなる。そして、天板２の後面寄りに形成された本体排気口１７から本体１の外に排気される。 The air flow in the left first cooling means and the right first cooling means is substantially J-shaped in a side view. In other words, the outside air flowing in from the main body inlet 4 forms a wind flow W11 toward the rear surface in the first duct suction portion 11 disposed near the bottom surface of the main body 1. And the direction of a flow is changed in the 1st duct connection part 13, it becomes the wind flow W13, and also the wind flow W14 toward the front surface 1f is formed in a 1st duct cooling part.
And since the 1st duct exhaust port 15 opened in the center side of the left-right direction of the main body 1 is formed in the termination | terminus part (equivalent to the lower part of the coil base 6) of the 1st duct cooling part 14, left 1st The wind flows W15a and W15b that have flowed into the main body 1 from the 1 duct exhaust port 15a and the right first duct exhaust port 15b become wind flows W16a and W16b that flow toward the rear surface while colliding with each other at substantially the center. And it exhausts out of the main body 1 from the main body exhaust port 17 formed near the rear surface of the top plate 2.

（第２冷却手段における風流れ）
一方、操作制御部８を構成する部品としては特に発熱が大きいものは無いが、搭載される表示部（例えば液晶パネル等）や制御用のマイコン等が高温の雰囲気下にさらされると、その動作に影響を及ぼし正常な動作が行えなくなる可能性がある。
誘導加熱調理器１００の場合、誘導加熱コイル５の発熱が天板２を経由する伝熱によって、あるいは誘導加熱コイル５を冷却した後で本体１の内部に流入した温められた空気からの操作制御部保持部材９を経由する伝熱によって、操作制御部８は高温となるから、前記正常は動作を保証するため、操作制御部８の冷却は必要となる。 (Wind flow in the second cooling means)
On the other hand, there are no parts that make up the operation control unit 8 that generate a large amount of heat. However, if the mounted display unit (such as a liquid crystal panel) or a control microcomputer is exposed to a high-temperature atmosphere, its operation May affect normal operation and prevent normal operation.
In the case of the induction heating cooker 100, the operation control from the heated air that has flowed into the main body 1 due to heat generated by the induction heating coil 5 through heat transfer through the top plate 2 or after the induction heating coil 5 has been cooled. Since the operation control unit 8 becomes high temperature due to heat transfer through the unit holding member 9, the operation control unit 8 needs to be cooled in order to ensure normal operation.

左第１ダクト吸引部１１ａに流入した外気の一部は、左第２ファン２２ａに吸引されて左第２ダクト吸引部２１ａに流入する風流れＷ２１ａとなった後、第２ダクト冷却部２３に流入する。そして、第２ダクト冷却部２３において、左右方向の中央に向かう略水平方向の風流れＷ２３ａを形成する。やがて、第２ダクト排気口２４から風流れＷ２４となって、本体１の内部に流出して風流れＷ１５ａ、Ｗ１５ｂまたは風流れＷ１６ａ、Ｗ１６ｂと混ざり合い、本体排気口１７から本体１の外に排気される。
同様に、右第１ダクト吸引部１１ｂに流入した外気の一部は、右第２ファン２２ｂに吸引されて右第２ダクト吸引部２１ｂに流入する風流れＷ２１ｂとなった後、第２ダクト冷却部２３に流入する。そして、第２ダクト冷却部２３において、左右方向の中央に向かう略水平方向の風流れＷ２３ｂを形成し、やがて、第２ダクト排気口２４から本体１の内部に流出して、風流れＷ１５ａ、Ｗ１５ｂまたは風流れＷ１６ａ、Ｗ１６ｂと混ざり合って、本体排気口１７から本体１の外に排気される。 Part of the outside air flowing into the left first duct suction part 11a is sucked by the left second fan 22a and becomes a wind flow W21a flowing into the left second duct suction part 21a, and then enters the second duct cooling part 23. Inflow. And in the 2nd duct cooling part 23, the substantially horizontal wind flow W23a which goes to the center of the left-right direction is formed. Eventually, the second duct exhaust port 24 becomes the wind flow W24, flows out into the main body 1 and mixes with the wind flows W15a and W15b or the wind flows W16a and W16b, and is exhausted from the main body exhaust port 17 to the outside of the main body 1. Is done.
Similarly, after a part of the outside air flowing into the right first duct suction part 11b is sucked into the right second fan 22b and becomes a wind flow W21b flowing into the right second duct suction part 21b, the second duct cooling is performed. Flows into the section 23. And in the 2nd duct cooling part 23, the substantially horizontal wind flow W23b which goes to the center of the left-right direction is formed, and eventually flows out into the inside of the main body 1 from the 2nd duct exhaust port 24, and wind flow W15a, W15b. Or it mixes with wind flow W16a and W16b, and is exhausted out of the main body 1 from the main body exhaust port 17. FIG.

前記のように、操作制御部８の発熱量は比較的少ないため、操作制御部８の温度を測定しながら、冷却の必要度に応じて、左第２ファン２２ａまたは右第２ファン２２ｂの両方または一方を、起動したり停止したりする制御をするようにしてもよい。
また、以上は、左誘導加熱コイル５ａおよび右誘導加熱コイル５ｂの両方に通電する加熱情報が入力された場合について説明しているが、左誘導加熱コイル５ａまたは右誘導加熱コイル５ｂの一方に通電する加熱情報が入力された場合においても、原則、左第２ファン２２ａおよび右第２ファン２２ｂの両方を運転するものであるが、操作制御部８の温度を測定しながら、冷却の必要度に応じて、左第２ファン２２ａまたは右第２ファン２２ｂの両方または一方を、起動したり停止したりする制御をするようにしてもよい。このとき、停止している第１ファン１２側の第１ダクト吸引部１１ではエジェクタ効果がないため、停止している第１ファン１２側の第２ファン２２を運転する方が、省エネに寄与する。 As described above, since the heat generation amount of the operation control unit 8 is relatively small, both the left second fan 22a and the right second fan 22b are measured while measuring the temperature of the operation control unit 8 depending on the necessity of cooling. Or you may make it carry out control which starts or stops one side.
Moreover, although the above demonstrated the case where the heating information which supplies with electricity to both the left induction heating coil 5a and the right induction heating coil 5b was input, it supplies with electricity to one of the left induction heating coil 5a or the right induction heating coil 5b. Even when the heating information to be input is input, in principle, both the left second fan 22a and the right second fan 22b are operated. However, the temperature of the operation control unit 8 is measured and the cooling is required. Accordingly, it is possible to control to start or stop both or one of the left second fan 22a and the right second fan 22b. At this time, since there is no ejector effect in the first duct suction part 11 on the side of the first fan 12 that is stopped, the operation of the second fan 22 on the side of the first fan 12 that is stopped contributes to energy saving. .

以上、実施の形態１として、一対の誘導加熱コイル５が設置された誘導加熱調理器１００を例示しているが、本願発明はこれに限定するものではなく、誘導加熱コイル５が１台であっても、３台以上であってもよい。
たとえば、誘導加熱コイル５が１台の場合には、左第１冷却手段または右第１冷却手段の一方が設置されることになる。
たとえば、誘導加熱コイル５が３台の場合には、それぞれに対応した３台の第１冷却手段が設置される。そして、３台の第１冷却手段の第１ダクト吸引部にそれぞれ連通した１台の第２冷却手段が設置されたり、２台の第１冷却手段の第１ダクト吸引部にそれぞれ連通した１台目の第２冷却手段と、残り１台の第１冷却手段の第１ダクト吸引部に連通した２台目の第２冷却手段と、が設置されたりする。 As described above, the induction heating cooker 100 in which the pair of induction heating coils 5 is installed is illustrated as the first embodiment, but the present invention is not limited to this, and the induction heating coil 5 is one. Or three or more units may be used.
For example, when there is one induction heating coil 5, one of the left first cooling means or the right first cooling means is installed.
For example, when there are three induction heating coils 5, three first cooling means corresponding to each are installed. Then, one second cooling means communicating with the first duct suction portions of the three first cooling means is installed, or one unit communicating with the first duct suction portions of the two first cooling means, respectively. The second cooling means of the eyes and the second second cooling means communicating with the first duct suction part of the remaining one first cooling means may be installed.

（効果）
以上のように誘導加熱調理器１００は、本体吸気口４から第１ダクト吸引部１１に外気（冷却用空気）を取り込んだ後、発熱量の比較的多い誘導加熱コイル５及び加熱制御部７を冷却するための外気と、発熱量の少ない操作制御部８を冷却するための外気とを分流するため、第１ダクト吸引部１１の上流において分岐する第２ダクト吸引部２１を設けている。このため、操作制御部８は、誘導加熱コイル５等を冷却した後の温度の高い空気を使用することなく、本体吸気口４から取り込んだままの外気（温度の低い外気）によって冷却することができるから、操作制御部８を効率よく冷却することができる。 (effect)
As described above, the induction heating cooker 100 includes the induction heating coil 5 and the heating control unit 7 that generate a relatively large amount of heat after taking outside air (cooling air) from the main body inlet 4 into the first duct suction unit 11. In order to divide the outside air for cooling and the outside air for cooling the operation control unit 8 that generates a small amount of heat, a second duct suction unit 21 that branches upstream of the first duct suction unit 11 is provided. For this reason, the operation control unit 8 can be cooled by outside air (low temperature outside air) taken in from the main body inlet 4 without using high temperature air after cooling the induction heating coil 5 and the like. Therefore, the operation control unit 8 can be efficiently cooled.

また、第２ダクト吸引部の一部と第２ダクト冷却部が、操作制御部保持部材９によって一体的に形成され、且つ、操作制御部保持部材９は天板２と密着するように保持され、ているから、誘導加熱コイル５及び加熱制御部７を冷却した後の温度の高い空気が、第２ダクト冷却部２３（操作制御部８を収容している）側へ侵入しないようにしているので、操作制御部８が、誘導加熱コイル５を冷却した高温の空気にさらされることが無く、操作制御部８の温度上昇を抑えることが可能になる。 Further, a part of the second duct suction part and the second duct cooling part are integrally formed by the operation control part holding member 9, and the operation control part holding member 9 is held so as to be in close contact with the top plate 2. Therefore, the high-temperature air after cooling the induction heating coil 5 and the heating control unit 7 is prevented from entering the second duct cooling unit 23 (containing the operation control unit 8). Therefore, the operation control unit 8 is not exposed to the high-temperature air that has cooled the induction heating coil 5, and the temperature increase of the operation control unit 8 can be suppressed.

また、発熱量の比較的大きい誘導加熱コイル５と加熱制御部７を冷却する第１ファン１２と、発熱量の比較的少ない操作制御部８を冷却する第２ファン２２と、を別に設けるように構成しているので、それぞれ必要に応じた能力のファン容量とすることが可能となる。このため、過剰な能力を持つファンを設置する必要が無いため、誘導加熱調理器１００の小形化及び低コスト化が可能になる。
また、左誘導加熱コイル５ａに対応した左第１ファン１２ａ及び左第２ファン２２ａと、右誘導加熱コイル５ｂに対応した右第１ファン１２ｂ及び右第２ファン２２ｂと、をそれぞれ備えているため、誘導加熱コイル５の片方運転または両方運転など、加熱に応じたファン駆動が可能になり、省電力化を図ることができるという効果を奏する。 Further, the induction heating coil 5 having a relatively large amount of heat generation, the first fan 12 that cools the heating control unit 7, and the second fan 22 that cools the operation control unit 8 having a relatively small amount of heat generation are separately provided. Since it is configured, it becomes possible to make the fan capacities of the respective capacities as required. For this reason, since it is not necessary to install a fan with excessive capacity, the induction heating cooker 100 can be reduced in size and cost.
Moreover, since the left first fan 12a and the left second fan 22a corresponding to the left induction heating coil 5a and the right first fan 12b and the right second fan 22b corresponding to the right induction heating coil 5b are provided, respectively. In addition, fan driving according to heating, such as one-side operation or both-operation of the induction heating coil 5, can be performed, and power saving can be achieved.

また、誘導加熱コイル５及び加熱制御部７を冷却した後の温度の高い（昇温量の多い）空気と、操作制御部８を冷却した後の比較的温度の低い（昇温量の少ない）空気と、が本体１の内部で混合されて本体１の外に排気されるように構成しているので、前者が後者と混合されることになるため、本体１の外へ排出される排気の温度を下げることが出来るため、誘導加熱調理器１００の周辺の温度上昇を少なくすることができる。 In addition, the air after the induction heating coil 5 and the heating control unit 7 are cooled (high temperature rise) and the temperature after the operation control unit 8 is cooled are relatively low (low temperature rise). Since the air is mixed inside the main body 1 and exhausted outside the main body 1, the former is mixed with the latter, so that the exhaust discharged outside the main body 1 Since the temperature can be lowered, the temperature rise around the induction heating cooker 100 can be reduced.

［実施の形態２：誘導加熱調理器］
図６〜図８は、本発明の実施の形態２に係る誘導加熱調理器の模式的に説明するものであって、図６は側面から内部構成がわかるように示した内部構成図とともにシステムキッチンへ組み込んだ場合の側面図、図７は上面から見た透視図である。図８は冷却風の流れを模式的に説明する側面視の断面図である。なお、実施の形態１と同じ部分または相当する部分にはこれと同じ符号を付し、一部の説明を省略する。 [Embodiment 2: Induction heating cooker]
6 to 8 schematically illustrate the induction heating cooker according to the second embodiment of the present invention, and FIG. 6 is a system kitchen together with an internal configuration diagram showing the internal configuration from the side. FIG. 7 is a perspective view seen from the top surface. FIG. 8 is a cross-sectional view in side view for schematically explaining the flow of cooling air. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and a part of description is abbreviate | omitted.

図６〜図８において、誘導加熱調理器２００は、操作制御保持部材９の前面９ｆの一部に第２ダクト切欠部２５（図７において、３箇所の場合を例示している）が設けられ、第２ダクト切欠部２５の位置に対応した本体１の前面１ｆの位置に、本体前面排気口１８が設けられた点において、誘導加熱調理器１００（実施の形態１）と相違し、その他の点においては同じものである。
したがって、誘導加熱調理器２００では、操作制御部８を冷却した後の空気の一部は、第２ダクト切欠部２５および本体前面排気口１８を通過して、本体１の前面１ｆから外に排気され、風流れＷ２５を形成する。なお、その他の風流れについては実施の形態１と同様なので説明を省略する。 6-8, the induction heating cooking appliance 200 is provided with the 2nd duct notch part 25 (in FIG. 7, the case of three places is illustrated) in a part of front surface 9f of the operation control holding member 9. In FIG. The main body front surface exhaust port 18 is provided at the position of the front surface 1f of the main body 1 corresponding to the position of the second duct notch 25, and is different from the induction heating cooker 100 (Embodiment 1). The point is the same.
Therefore, in the induction heating cooker 200, a part of the air after cooling the operation control unit 8 passes through the second duct notch 25 and the main body front exhaust port 18 and exhausts outside from the front surface 1 f of the main body 1. The wind flow W25 is formed. Since other wind flows are the same as those in the first embodiment, description thereof is omitted.

したがって、誘導加熱調理器２００は、操作制御部８を冷却した後の比較的温度の低い（昇温の少ない）空気の一部を、直接本体１の外に排気するように構成しているため、システムキッチンへ組み込んだ際に、本体前面排気口１８から排気される比較的低温の空気がカウンタートップ３０に吹き付けられるから、カウンタートップ３０の温度上昇を抑制することが可能になるという効果を奏する。
特に、ロースター３を同時に使用する場合には、ロースター３の周辺の温度上昇によりカウンタートップ３０の温度も上昇するため、効果が顕著になる。 Therefore, the induction heating cooker 200 is configured to exhaust a part of the air having a relatively low temperature (low temperature rise) after cooling the operation control unit 8 directly out of the main body 1. Since the relatively low temperature air exhausted from the front exhaust port 18 of the main body is blown to the countertop 30 when it is incorporated into the system kitchen, the temperature rise of the countertop 30 can be suppressed. .
In particular, when the roaster 3 is used at the same time, the temperature of the countertop 30 also rises due to the rise in the temperature around the roaster 3, so the effect becomes remarkable.

［実施の形態３：誘導加熱調理器］
図９は、本発明の実施の形態３に係る誘導加熱調理器を模式的に説明するものであって、側面から内部構成がわかるように示した内部構成図とともにシステムキッチンへ組み込んだ場合の側面図である。なお、実施の形態２と同じ部分または相当する部分にはこれと同じ符号を付し、一部の説明を省略する。
図９において、誘導加熱調理器３００は、ロースター３のロースター加熱制御部７ｒが左第１ダクト吸引部１１ａ（右第１ダクト吸引部１１ｂであってもよい）に配置された点において、誘導加熱調理器２００（実施の形態２）と相違し、その他の点においては同じものである。 [Embodiment 3: Induction heating cooker]
FIG. 9 schematically illustrates an induction heating cooker according to Embodiment 3 of the present invention, and is a side view when incorporated in a system kitchen together with an internal configuration diagram shown so that the internal configuration can be seen from the side surface. FIG. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 2, or an equivalent part, and one part description is abbreviate | omitted.
In FIG. 9, the induction heating cooker 300 is the induction heating in the point that the roaster heating control part 7r of the roaster 3 is arranged in the left first duct suction part 11a (may be the right first duct suction part 11b). It differs from cooker 200 (Embodiment 2) and is otherwise the same.

したがって、左第１ファン１２ａが吸引した外気によって、ロースター加熱制御部７ｒは効果的に冷却されると共に、ロースター加熱制御部７ｒが左第１ダクト吸引部１１ａ内に収納されたことによって、本体１の内部における部材配置の自由度が増し、スペースの有効利用や本体の小型化、あるいは、より好適な風路設計を図ることが可能になる。
なお、ロースター加熱制御部７ｒの発熱量は比較的少ないため、当該配置によって左第１ダクト冷却部１４ａに配置された左誘導加熱コイル５ａおよび左加熱制御部７ａの冷却に支障が生じることはない。 Therefore, the roaster heating control unit 7r is effectively cooled by the outside air sucked by the left first fan 12a, and the roaster heating control unit 7r is housed in the left first duct suction unit 11a, whereby the main body 1 The degree of freedom of the arrangement of the members inside is increased, and it becomes possible to effectively use the space, downsize the main body, or to design a more suitable air path.
In addition, since the calorific value of the roaster heating control unit 7r is relatively small, this arrangement does not hinder the cooling of the left induction heating coil 5a and the left heating control unit 7a arranged in the left first duct cooling unit 14a. .

［実施の形態４：誘導加熱調理器］
図１０は、本発明の実施の形態４に係る誘導加熱調理器を模式的に説明するものであって、側面から内部構成がわかるように示した内部構成図とともにシステムキッチンへ組み込んだ場合の側面図である。なお、実施の形態２と同じ部分または相当する部分にはこれと同じ符号を付し、一部の説明を省略する。
図１０において、誘導加熱調理器４００は、誘導加熱調理器２００（誘導加熱調理器１００に同じ）に設置されていた電気ヒータ式の加熱口５ｈに代えて又は追加して、天板２の左右方向の中央で後面寄りに中央誘導加熱コイル５ｃが設置され、さらに、中央誘導加熱コイル５ｃに高周波電流を流す中央加熱制御部７ｃが左第１ダクト吸引部１１ａ（右第１ダクト吸引部１１ｂであってもよい）に配置された点において、誘導加熱調理器２００（実施の形態２）と相違し、その他の点においては同じものである。 [Embodiment 4: Induction heating cooker]
FIG. 10 schematically illustrates the induction heating cooker according to the fourth embodiment of the present invention, and the side surface when incorporated in the system kitchen together with the internal configuration diagram shown so that the internal configuration can be seen from the side surface. FIG. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 2, or an equivalent part, and one part description is abbreviate | omitted.
In FIG. 10, the induction heating cooker 400 is replaced with or added to the electric heater type heating port 5h installed in the induction heating cooker 200 (same as the induction heating cooker 100). A central induction heating coil 5c is installed near the rear surface in the center of the direction, and a central heating control unit 7c for supplying a high-frequency current to the central induction heating coil 5c is connected to the left first duct suction unit 11a (the right first duct suction unit 11b). It is different from the induction heating cooker 200 (Embodiment 2) in that it may be disposed), and the other points are the same.

したがって、左第１ファン１２ａが吸引した外気によって、中央加熱制御部７ｃは効果的に冷却されると共に、中央加熱制御部７ｃが左第１ダクト吸引部１１ａ内に収納されたことによって、本体１の内部における部材配置の自由度が増し、スペースの有効利用や本体の小型化、あるいは、より好適な風路設計を図ることが可能になる。
なお、中央加熱制御部７ｃの発熱量は左加熱制御部７ａ等と較的して少ないため、当該配置によって左第１ダクト冷却部１４ａに配置された左誘導加熱コイル５ａおよび左加熱制御部７ａの冷却に支障が生じることはない。 Accordingly, the central heating control unit 7c is effectively cooled by the outside air sucked by the left first fan 12a, and the central heating control unit 7c is housed in the left first duct suction unit 11a. The degree of freedom of the arrangement of the members inside is increased, and it becomes possible to effectively use the space, downsize the main body, or to design a more suitable air path.
Since the heat generation amount of the central heating control unit 7c is smaller than that of the left heating control unit 7a and the like, the left induction heating coil 5a and the left heating control unit 7a arranged in the left first duct cooling unit 14a by this arrangement. There will be no hindrance to cooling.

以上より、本発明の誘導加熱調理器は、本体内の前方に配置される操作制御部を効率よく冷却することができるから、家庭用および業務用の各種誘導加熱調理器として広く利用することができる。 As mentioned above, since the induction heating cooker of this invention can cool the operation control part arrange | positioned ahead in a main body efficiently, it can utilize widely as various induction heating cookers for household use and business. it can.
