Description

【0001】
【発明の属する技術分野】
本発明は一般家庭で使用するロースタ部を有する誘導加熱調理器に関し、特に、器体の外面温度を低減したものに関する。
【0002】
【従来の技術】
従来、この種の誘導加熱調理器としては、高温になるロースタ加熱装置の前面開口部を除くロースタ加熱装置の外面に仕切り板を設け、仕切り板で2重遮蔽した箱体となし、遮蔽層である仕切り板に冷却風導入口を設け、前記冷却風導入口から導いた冷却風でロースタ加熱装置を冷却した後、器体背面外郭側から器体上面後部の排気口から排気されることにより、ロースタ加熱装置を冷却するようなものがあった。以下、図7、8を用いて説明する。
【0003】
図7は従来の誘導加熱調理器の分解斜視図、図8は同ロースタ加熱装置の斜視図である。図において、本体1の内部には加熱コイル2および3が配設され、さらに下方の略中央には本体1の内部を仕切り板4で仕切り、ロースタ加熱装置5を配したロースタ室6が設けられている。また、仕切り板4の両側には、右冷却装置7と左冷却装置8が配設されている。仕切り板4の前方には右前導入口9があり、右冷却装置7により冷却風が右前導入口9からロースタ加熱装置5側に流れ込み、ロースタ加熱装置5と本体1底面の間を前方から後方に流れ、排気口11から排気される甲冷却風路11が形成されている。
【0004】
また、冷却風が仕切り板4の後方に開口した右後導入口12からロースタ加熱装置5側に流れ込み、ロースタ加熱装置5の後面下方から上方に上昇して排気口10から排気される乙冷却風路13が形成されている。
【0005】
さらに、右冷却装置7により冷却風が右制御装置14の上方を通って仕切り板4の上面に沿って前方から後方に流れ、排気口10から排気される丙冷却風路15が形成されている。
【0006】
以上のように冷却風路を構成することで、バランスよくしかも全体的に効率よくロースタ加熱装置が冷却され、ロースタ加熱装置の冷却効率を向上させるとともに、加熱コイルや、制御装置の温度上昇が抑止されるというものであった(例えば、特許文献1参照)。

【0008】
【発明が解決しようとする課題】
近年、誘導加熱調理器の普及に伴い、それを用いた調理範囲が拡大するにつれて、現在の火力では物足らずさらに大きな出力、例えば、20%程度出力を増加した誘導加熱調理器が要望されるようになってきた。しかしながら、誘導加熱調理器のように一般家庭の台所で使用されるよな機器では、台所の広さからその寸法が制約される。特に、流し台に組み込んで使用するような場合は、組み込みができるように寸法が規制されていた。そこで、現状の寸法を維持したまま出力を増加する事が考えられた。
【0009】
しかるに、従来の構成では、ロースタ加熱装置5の周囲を冷却する甲冷却風路11および、乙冷却風路13はロースタ加熱装置5の周囲を通過して高温になった後、排気口10に達する手前で本体1の外郭後面16に沿って流れるので、外郭後面16は高温の熱気に晒されることになる。したがって、寸法が規制されているため、従来の寸法および構成のままで出力を増加すると、その分排気の温度は高くなり外郭後面の温度も高くなる。そのため、使用時に誤って触れると火傷する危険性があるり、これを防ぐために外郭後面の温度を低減しなければならないという課題が生じてきた。
【0010】
本発明は、前記従来の課題を解決するもので、ロースタ加熱装置後方に位置する本体外郭後面がロースタ加熱装置を冷却した高温排気に直接さらされないようにして、温度上昇の低減を図り安全性を向上した誘導加熱調理器を提供することを目的とする。
【0011】
【課題を解決するための手段】
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ロースタ部後方に位置する本体外郭後面の内側に、前記本体外郭後面と少なくとも前記ロースタ部後部との間を仕切る仕切り壁を設け、前記本体外郭後面と仕切り壁との間に空間を確保する構成とした。この構成により、ロースタ加熱装置を冷却した高温の排気が仕切り壁に沿って上昇し排気口より排気されるため、本体外郭後面は高温の排気に直接晒される事なく、しかも、高温となる仕切り壁との間には空間があるため熱伝導による熱伝達が抑えられ温度が上昇しにくくなる。
【0012】
【発明の実施の形態】
請求項1に記載の発明は、外郭を構成する本体と、前記本体の上面に設けたトッププレート、吸気口および排気口と、前記トッププレートに載置した鍋等の被加熱物を高周波加熱する加熱コイルと、前記加熱コイルの出力を制御する出力制御部と、前記本体内に設けた冷却ファンと、前記本体内に設け前記出力制御部とは独立した部位を形成するロースタ部とを備え、前記ロースタ部後方に位置する前記本体外郭後面の内側に、前記本体外郭後面と少なくとも前記ロースタ部後部との間を仕切る仕切り壁を設け、前記本体外郭後面と仕切り壁との間に空間を確保する構成とした。この構成により、ロースタ加熱装置を冷却した高温の排気が仕切り壁に沿って上昇し排気口より排気されるため、本体外郭後面は高温の排気に直接晒される事なく、しかも、高温となる仕切り壁との間には空間があるため熱伝導による熱伝達が抑えられ温度が上昇しにくくなる。したがって、本体外郭後面の温度を低減することができる。
【0013】
請求項2に記載の発明は、特に、請求項1に記載の構成において、本体外郭後面に開口を設け、前記仕切り壁と前記本体外郭後面との間の空間に、前記ロースタ部の周囲を通過した熱気とは別の冷却風を通す通風路を設ける構成した。この構成により、排気口直前の通風経路である本体外郭が加熱室周囲を通過した高温熱気に晒されなくなり温度の低減を図ることができると共に、ひいては本体を設置するキッチン台の温度上昇も低減することができる。
【0014】
請求項3に記載の発明は、特に、請求項2に記載の構成において、空間を仕切る壁の冷却ファン側に導入口を設け、前記冷却ファンからの冷却風が、前記導入口から前記仕切り壁と前記本体外郭後面との間の空間を通り、前記本体外郭後面の開口に至る通風路を形成する構成とした。この構成により、冷却ファンによる送風圧により導入口から、仕切り壁と本体後面外郭との空間を通り、本体外郭後面の開口に至る通風路が構成される。したがって、ロースタ加熱装置の高温排熱は仕切り壁で止められ、空間には、ロースタ加熱装置の高温排熱を排除した冷却風が流れ、ロースタ後方に位置する本体外郭後面の温度が低減するとともに、器体を設置するキッチン台の温度上昇も低減することができる。かつ、冷却ファンから排気口に至る排気経路は、前記通気路が新たに追加されるので排気抵抗は低減され、冷却ファンの能力低下を生じることなく実施することができる。
【0015】
請求項4に記載の発明は、特に、請求項3に記載の空間を、仕切り壁と本体外郭後面との間隔は導入口に近い方が広く、導入口から離れるにしたがって狭くなる構成としたことにより、導入口より導入された冷却風は空間の奥の方まで到達しやすくなるので、本体外郭後面の温度分布を小さくすることができる。
【0016】
請求項5に記載の発明は、特に、請求項2に記載の構成において、本体外郭後面に複数の開口を設け、仕切り壁と本体外郭後面との間の空間に外気が前記開口の下部から流入し、前記開口の上部より流出する通風路を形成する構成した。この構成により、仕切り壁がロースタ加熱装置の高温排熱を受け止め、仕切り壁と本体外郭後面との間の空間には、本体外郭後面に設けた開口から自然対流で出入りする通風路が構成され、本体外郭後面温度の低減を図ることができる。
【0017】
請求項6に記載の発明は、特に、請求項1〜5のいずれか1項に記載の空間に断熱材を挿入することにより、ロースタ加熱装置からの熱を遮断し、本体外郭後面の温度を低減することができる。
【0018】
請求項7に記載の発明は、特に、請求項1〜6のいずれか1項に記載の構成において、仕切り壁のロースタ部に対向する面および本体外郭後面の仕切り壁に対向する面の少なくとも一方に熱反射層を設ける構成としたことにより、熱輻射を反射するので仕切り壁または本体外郭後面の温度上昇を抑えることができる。
【0019】
請求項8に記載の発明は、特に、請求項1〜7のいずれか1項に記載の本体外郭後面に輻射層を設ける構成としたことにより、本体外郭後面からの輻射熱を多くすることができるので本体外郭後面の温度を低減することができる。
【0020】
【実施例】
本発明の特徴は本体外郭後面の表面温度を低減するためにロースタ部と本体外郭後面との間に仕切り壁により空間を設けたことである。以下、本発明の実施例について、図面を参照しながら説明する。なお、本実施例の説明にあたっては誘導加熱部を左右に有するいわゆる2口のコンロ部と魚などを焼くロースタ部を有する誘導加熱調理器の場合について説明する。
【0021】
(実施例1)
図1は本発明の実施例1における誘導加熱調理器の破断平面図、図2は同誘導加熱調理器の分解斜視図、図3は同誘導加熱調理器の要部拡大断面図、図4は同誘導加熱調理器の外観背面図である。
【0022】
図において、21は外郭を構成する本体、22は本体21の上面に設けたトッププレート、23はトッププレート22を保持するトップフレームであり、トップフレーム23の後部には吸気口24と排気口25とを設けている。26、27はトッププレート22下方に設けたは加熱コイルで、トッププレート22に載置した被加熱物を誘導加熱し加熱調理する。28は加熱コイル26、27の出力を制御する出力制御部である。29は冷却風を発生する冷却ファン、30は魚などを焼くロースタ加熱装置を有するロースタ部である。
【0023】
また、31はロースタ部30の後方に位置する本体外郭後面、32は本体外郭後面に設けられた開口である。33は本実施例の特徴である仕切り壁で、本体外郭後面31とロースタ部30との間に空間33を形成するように設けている。また、この空間33にはロースタ加熱装置を冷却して高温となった冷却風が回り込んでこないようにしている。35は内部隔壁で出力制御部および冷却ファンを配する部位とロースタ部とを仕切っており、その後部の本体外郭後面31の近くに冷却風を導入する導入口36を設けている。この構成において仕切り壁33の一端は本体21の側面に、他端は内部隔壁35の側面に夫々密接に取付けている。したがって、本実施例の空間34の構成は、その前後を仕切り壁33と本体外郭後面31とで、左右を本体の側面と内部隔壁とで、さらに上下は本体に設けられた上板と下板とで仕切られた構成となっている。これにより、導入口から導入された冷却風が開口32より排出するようにしている。
【0024】
以上のように構成された誘導加熱調理器について、以下、その動作作用を説明する。
【0025】
冷却ファン29は送風圧を発生するので本体21内部の圧力が高まり、本体21内に開口や通気経路があると、冷却ファン29からの冷却風をこれら開口や通気経路を通って本体外に排出する。したがって、内部隔壁35に設けた導入口36から、仕切り壁33と本体外郭後面31との間の空間34を経由し、本体外郭後面31の開口32に至る矢印で示す通風路Pを形成する。
【0026】
本体21内の主冷却経路は、図2に示すように、冷却ファン29から出力制御部28を通り、加熱コイル27を通過した後、本体21内左の通気孔からロースタ部30の左を通り、本体外郭後面31内面を通過して排気口25に達する流れである。これに加え、冷却ファン29から内部隔壁35の導入口36に入る流れが形成され、これが通風路Pを流れる経路となる。通風路Pには、ロースタ部30周囲を通過した熱気は流れず、温度上昇が比較的低い出力制御部28を通過した冷却風が供給されるので、ロースタ部30の後方に位置する本体外郭後面31の部分の温度は低減する。
【0027】
さらに、本体21の後方には誘導加熱調理器を設置するキッチン台の壁があるが、ここに当たる排熱温度が下がることに加え、排気口25から出る熱気を通風路Pから出る排気で押し上げるので、キッチン台の温度上昇も低減できる。かつ、冷却ファンから排気口に至る排気経路は、主冷却経路に加え通風路Pを通る冷却経路が補助的に追加されるので、冷却ファン29の排気抵抗は低減され、冷却ファン29の能力低下を生じることなく、したがって、冷却ファン29の能力を増加することなく温度の低下を図ることができる。
【0028】
なお、本体外郭後面31に設けた開口32は図4ではロースタ加熱装置に対応する部分のほぼ前面に一様に設けているが、上部に行くにしたがって、開口の大きさを大きくすると冷却効率がよくなる。また、開口は上部のみまたは左上部としても良いが、これは機種により効率よく冷却できるように検討し、定めればよい。
【0029】
以下、具体的な実施例について述べる。
【0030】
2口の誘導加熱部と1つのロースタ部とを有する誘導加熱調理器で、消費電力を4000Wから4800Wに20%出力を増加した場合、従来の構成のまま出力を増加したとき本体外郭後面31の温度は85℃を超える場合があった。これは、電気用品安全法の別表第八の附表第四における「温度限度」に記載されている温度85℃を超えるものである。一方、本実施例の構成で空間34の間隔を10mmとして出力を20%増加したとき本体外郭後面31の温度は80℃であり前記規格を充分満足するものであった。このように本実施例の方法によれば、充分な冷却効果が得られるとともに、10mm程度の空間であれば器体内部で吸収することができるため器体の外形を大きくせずに実施できる。また、器体を大きくする必要があっても実質的には2〜3mm程度で済ますことができるため、器体の外形寸法を据え付けのための規制値以内に納めることができる。
【0031】
以上の説明では、空間34の間隔として10mmの場合について説明したが、寸法に余裕のある場合はさらに大きくしてもよいし、また、寸法に余裕のない場合は5mm程度にしても温度の低減効果はほとんど変わらない。間隔が5mmより狭くなると温度低減効果は急速に低下してくる。したがって、このような場合は新たにファンなどを取付け冷却風の風力を強くするなどの他の手段が必要となる。
【0032】
また、本実施例では本体外郭後面31と仕切り壁33とはほぼ平行に設けているが、内部隔壁35に設けた導入口36に近い部分の本体外郭後面31と仕切り壁33との間隔を広くし、導入口36より離れるにしたがって狭くなるようにすると、冷却風が奥のほうまで良く行き渡るようになり本体外郭後面31の後面の温度分布が小さくなり好ましい。
【0033】
なお、本実施例では空間を上下および周囲を囲んだ状態の場合について説明したがこれに限定されるものではなく、設計によっては周囲からロースタ加熱装置を冷却した冷却風がはいってくる恐れがあまりない場合や、制限温度に余裕があり周囲からまたは上下から冷却風の一部が漏出しても良い場合などは本実施例の構成にこだわる必要はない。要は設けた空間に冷却風が導入され本実施例の主旨である本体外郭後面が充分に冷却されるならば空間の構成はどのようであってもよい。
【0034】
また、空間への冷却風の導入は前記構成に限定されるものではなく、本実施例の主旨にかなう冷却風を導入することができるならば、どのような通風路を設けても良いのは勿論である。
【0035】
また、本実施例では空間に冷却風を導入する場合について述べたが、設計によっては、または出力の増加率が低い、例えば、10パーセント程度の場合、あるいは消費電力が低い場合で、本体外郭後面の温度をそれほど低減する必要のない場合は、冷却風を導入しない構成としても良い。この場合、構成が簡単になるためあまり価格を上げることなく本体外郭後面の温度を下げることができる。
【0036】
また、仕切り壁と本体外郭後面との間の空間に断熱材を挿入しても本体外郭後面の温度を低減することができる。断熱材の巾は空間の巾よりも小さくても良い。このとき生じた隙間に本実施例のように冷却風を流すようにすると温度低減効果は大きくなる。断熱材としてはガラス繊維やシリか繊維などのように耐熱性を有する繊維からなるものが好ましい。とくに、断熱材として真空断熱材を用いると効果が大きい。それは、真空断熱材を用いて他の断熱材を用いた場合と同程度の断熱を行う場合、断熱材の厚つみを減らすことができ空間の巾を小さくすることができるからであり、また、空間の巾を一定としたときは断熱材を挿入した後の隙間の巾が大きくなるため、冷却風を導入する方式を用いた場合冷却風を流しやすくなるためである。この他、断熱材として無機中空体を空間に充填する方法もある。
【0037】
また、仕切り壁の内側、すなわちロースタ加熱装置がある高温側の面に熱線反射層を設けると、ロースタ加熱装置からの輻射線が反射され仕切り壁の温度を抑えることになり、仕切り壁からの輻射温度を低くすることができる。同様に、本体外郭後面の仕切り壁に対抗する面に熱線反射層を設けると同様の理由により本体外郭後面の温度を低減することができる。
【0038】
また、空間に冷却風を流しても流さなくても温度低減効果は得られるが冷却風を流した方が効果的なのは勿論である。なお、熱線反射層としては種々あるが、仕切り壁あるいは本体外郭後面にアルミニウム箔をラミネートするか、あるいはアルミニウムを含有した塗装膜を設けるかするのが価格的に有利である。なお、熱線反射層は本体外郭後面と仕切り板の両方に設けても良いのは勿論である。
【0039】
また、従来の誘導加熱調理器では本体外郭後面の温度があまり問題にならず、かつ本体外郭後面は人目に触れにくいため板金をそのまま用いるのが一般的であった。しかるに、本発明のように本体外郭後面の温度を低減する必要があるときは本体外郭後面の外側に輻射層を設けると本体外郭後面からの輻射が多くなり、その温度を低減することができる。なお、輻射層としては塗装膜でもその効果を充分に発揮できる。
【0040】
なお、空間に断熱材を挿入したり、本体外郭後面や仕切り壁に熱線反射層を設けたり、あるいは本体外郭後面に輻射層を設けたりする手段は単独で用いても良いが組合わせて用いるとさらに温度低減効果が得られる。
【0041】
(実施例2)
図5は本発明の実施例2における誘導加熱調理器の要部断面図、図6は同誘導加熱調理器の他の例の要部断面図である。なお、本実施例の基本構成は実施例1と同じなので異なる点を中心に説明する。また、実施例1と同じ機能には同じ符号を付しその説明は省略する。
【0042】
本実施例が実施例1と異なる点は、実施例1が空間34に冷却風を導入するにあたって、冷却ファン29で発生した冷却風を内部隔壁35の導入口36より強制的に導入し冷却するのに対し、本実施例では内部隔壁35には導入口は設けず本体外郭後面31に設けた上下の開口により行われる自然対流により冷却する点である。
【0043】
図5において、仕切り壁33と本体外郭後面31との間に形成した空間34に下部開口37より浸入した外気は空間34を通って上部開口38より外部へ排出する。この自然対流の過程で仕切り壁33より熱を奪い仕切り壁33を冷却し輻射温度を低減すると共に、本体外郭後面31に外気が接触し冷却するのでその温度が上昇するのを抑制することができる。
【0044】
また、図6は下部開口37および上部開口38に切起こし39を設けたもので、これにより自然対流がより促進される。なお、上部開口38の切起こし39は下向けにしてもよく、また設けなくても良い。
【0045】
なお、上部開口38は空間34の頂部にも受けても良い。このとき外部への排気路も確保する必要がある。また、実施例1同様に空間に断熱材を挿入したり、熱反射層や輻射層を設けたり、あるいはこれらを組合わせて使用したりすることにより実施例1と同様の効果を得ることができる。
【0046】
このように本実施例によれば簡単な構成により本体外郭後面の温度を低減することができる。
【0047】
以上、実施例1および2では誘導加熱調理器として2口の誘導加熱部と1つのロースタ部を有する誘導加熱調理器について述べたが、これに限定されるものではなく、2口の誘導加熱部と1口の輻射加熱部および1つのロースタ部を有する誘導加熱調理器であっても良いし、1つのロースタ部と他の1つまたは複数の加熱部とを有する誘導加熱調理器であってもよいのは勿論である。
【0048】
また、本実施例によれば、本体外郭後面と仕切り壁との間に空間を設け、この空間に冷却風を導入したり、断熱材を挿入したり、または熱反射層や輻射層を設けたり、並びにこれらを組合わせて使用することにより、本体外郭後面の温度を夫々の手段に応じて低減することができる。したがって、温度の低減割合は前記手段により異なるため、消費電力の大きさ、消費電力の増加率の割合、または必要とする低減温度などに基づいて定めたらよい。
【0049】
以上述べたように本実施例によれば簡単な構成で、外形寸法をほとんど大きくすることなく、本体外郭後面の温度を低減できるのでその実用的効果は大なるものがある。
【0050】
【発明の効果】
以上のように、請求項1ないし8に記載の発明によれば、ロースタ加熱装置の後方に位置する本体外郭後面がロースタ加熱装置を冷却した高温排気に直接さらされず、本体外郭後面の温度上昇の低減をすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an induction heating cooker having a roaster unit used in ordinary households, and more particularly to a cooker having a reduced outer surface temperature of the body.
[0002]
[Prior art]
Conventionally, as this type of induction heating cooker, a partition plate is provided on the outer surface of the roaster heating device except for the front opening portion of the roaster heating device, which is heated to a high temperature. By providing a cooling air introduction port to a certain partition plate, and cooling the roaster heating device with cooling air guided from the cooling air introduction port, by being exhausted from the exhaust port at the rear of the upper surface of the body from the outer side of the body back, Some have cooled roaster heating devices. Hereinafter, description will be made with reference to FIGS.
[0003]
FIG. 7 is an exploded perspective view of a conventional induction heating cooker, and FIG. 8 is a perspective view of the roaster heating device. In the figure, heating coils 2 and 3 are disposed inside a main body 1, and a roaster chamber 6 in which a rotater heating device 5 is disposed is provided at a substantially lower center by partitioning the inside of the main body 1 with a partition plate 4. ing. A right cooling device 7 and a left cooling device 8 are disposed on both sides of the partition plate 4. There is a right front inlet 9 in front of the partition plate 4, and cooling air flows from the right front inlet 9 to the roaster heating device 5 side by the right cooling device 7, so that the space between the roaster heating device 5 and the bottom surface of the main body 1 is moved from front to back. An instep cooling air passage 11 that flows and is exhausted from the exhaust port 11 is formed.
[0004]
In addition, the cooling air flows into the roaster heating device 5 from the right rear inlet 12 opened behind the partition plate 4, rises upward from below the rear surface of the roaster heating device 5, and is exhausted from the exhaust port 10. A passage 13 is formed.
[0005]
Further, the right cooling device 7 allows the cooling air to flow from the front to the rear along the upper surface of the partition plate 4 above the right control device 14 through the upper portion of the right control device 14, thereby forming a cooling air passage 15 exhausted from the exhaust port 10. .
[0006]
By configuring the cooling air path as described above, the roaster heating device is cooled in a well-balanced and efficient manner, improving the cooling efficiency of the roaster heating device and suppressing the temperature rise of the heating coil and the control device. (For example, see Patent Document 1).

[Problems to be solved by the invention]
In recent years, with the spread of induction heating cookers, as the range of cooking using them has expanded, current heating power is not sufficient, and an induction heating cooker that has increased the output, for example, about 20% has been demanded. It has become However, the size of an appliance such as an induction heating cooker used in a general home kitchen is limited by the size of the kitchen. In particular, when it is used by being incorporated in a sink, the dimensions have been restricted so that it can be incorporated. Therefore, it was considered to increase the output while maintaining the current dimensions.
[0009]
However, in the conventional configuration, the upper cooling air passage 11 and the second cooling air passage 13 that cool the periphery of the roaster heating device 5 pass through the periphery of the roaster heating device 5 and reach a high temperature before reaching the exhaust port 10. Since it flows along the outer rear surface 16 of the main body 1 in the foreground, the outer rear surface 16 is exposed to high-temperature hot air. Therefore, since the size is regulated, if the output is increased while keeping the conventional size and configuration, the temperature of the exhaust increases and the temperature of the rear surface of the outer shell increases accordingly. For this reason, there has been a problem that there is a danger of burns if touched by mistake during use, and that the temperature of the rear surface of the outer shell must be reduced in order to prevent this.

With this configuration, a ventilation path is formed from the inlet through the space between the partition wall and the outer surface of the rear surface of the main body to the opening on the rear surface of the outer surface of the main body by the blowing pressure of the cooling fan. Accordingly, the high-temperature exhaust heat of the roaster heating device is stopped by the partition wall, and the cooling air that has eliminated the high-temperature exhaust heat of the roaster heating device flows in the space, and the temperature of the rear surface of the main body located behind the roaster decreases, The temperature rise of the kitchen table on which the container is installed can be reduced. In addition, the exhaust path from the cooling fan to the exhaust port is newly provided with the ventilation path, so that the exhaust resistance is reduced, and the exhaust path can be implemented without lowering the performance of the cooling fan.
[0015]
The invention described in claim 4 is that the space defined in claim 3 has a structure in which the distance between the partition wall and the rear surface of the outer shell of the main body is wider near the inlet and becomes narrower as the distance from the inlet increases. Thereby, the cooling air introduced from the inlet becomes easier to reach deeper into the space, so that the temperature distribution on the rear surface of the outer shell of the main body can be reduced.
[0016]
According to a fifth aspect of the present invention, in the configuration according to the second aspect, a plurality of openings are provided in the rear surface of the main body, and outside air flows into a space between the partition wall and the rear surface of the main body from the lower portion of the opening. Then, a ventilation passage flowing out from the upper part of the opening is formed.

[0020]
【Example】
A feature of the present invention is that a space is provided by a partition wall between the roaster section and the rear surface of the main body outer shell in order to reduce the surface temperature of the rear surface of the main outer shell. Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the present embodiment, the case of an induction heating cooker having a so-called two-port stove having left and right induction heating units and a roaster unit for baking fish and the like will be described.

It is an appearance back view of the induction heating cooker.
[0022]
In the figure, 21 is a main body constituting an outer shell, 22 is a top plate provided on the upper surface of the main body 21, 23 is a top frame holding the top plate 22, and an intake port 24 and an exhaust port 25 are provided at the rear of the top frame 23. Are provided. Reference numerals 26 and 27 denote heating coils provided below the top plate 22 for inductively heating and heating the object placed on the top plate 22. An output control unit 28 controls the outputs of the heating coils 26 and 27. 29 is a cooling fan for generating cooling air, and 30 is a roaster unit having a roaster heating device for baking fish and the like.
[0023]
Reference numeral 31 denotes a rear surface of the main unit outer side located behind the roaster unit 30, and 32 denotes an opening provided on the rear surface of the main unit outer periphery. Reference numeral 33 denotes a partition wall which is a feature of the present embodiment, and is provided so as to form a space 33 between the rear surface 31 of the main body outer shell and the roaster portion 30. In addition, the cooling air which has cooled the roaster heating device and has become high temperature does not enter this space 33. Reference numeral 35 denotes an internal partition which partitions a portion where the output control unit and the cooling fan are disposed from the roaster unit, and has an inlet 36 for introducing cooling air near the rear surface 31 of the main body. In this configuration, one end of the partition wall 33 is closely attached to the side surface of the main body 21, and the other end is closely attached to the side surface of the internal partition wall 35. Therefore, the configuration of the space 34 of the present embodiment is such that the front and rear are the partition wall 33 and the main body outer rear surface 31, the left and right are the main body side surface and the internal partition, and the upper and lower are the upper plate and the lower plate provided in the main body. The configuration is divided into Thus, the cooling air introduced from the inlet is discharged from the opening 32.
[0024]
The operation and operation of the induction heating cooker configured as described above will be described below.
[0025]
Since the cooling fan 29 generates a blowing pressure, the pressure inside the main body 21 increases, and if there is an opening or a ventilation path in the main body 21, the cooling air from the cooling fan 29 is discharged out of the main body through the opening or the ventilation path. I do. Therefore, a ventilation path P indicated by an arrow is formed from the inlet 36 provided in the inner partition wall 35 to the opening 32 of the main body outer rear surface 31 via the space 34 between the partition wall 33 and the main body outer rear surface 31.
[0026]
As shown in FIG. 2, the main cooling path in the main body 21 passes through the output control unit 28 from the cooling fan 29, passes through the heating coil 27, and then passes through the left vent hole in the main body 21 and to the left of the roaster unit 30. The flow passes through the inner surface of the rear surface 31 of the main body and reaches the exhaust port 25. In addition, a flow from the cooling fan 29 to the inlet 36 of the internal partition wall 35 is formed, and this is a path that flows through the ventilation path P. Hot air that has passed around the roaster unit 30 does not flow into the ventilation path P, and cooling air that has passed through the output control unit 28 whose temperature rise is relatively low is supplied. The temperature of the part 31 decreases.
[0027]
Further, behind the main body 21, there is a wall of a kitchen table on which an induction heating cooker is installed. In addition to a decrease in the exhaust heat temperature hitting the wall, the hot air coming out of the exhaust port 25 is pushed up by the exhaust air coming out of the air passage P. Also, the temperature rise of the kitchen table can be reduced. In addition, in the exhaust path from the cooling fan to the exhaust port, a cooling path passing through the ventilation path P is additionally provided in addition to the main cooling path, so that the exhaust resistance of the cooling fan 29 is reduced and the performance of the cooling fan 29 is reduced. Therefore, the temperature can be reduced without increasing the capacity of the cooling fan 29.
[0028]
Although the opening 32 provided in the rear surface 31 of the outer shell of the main body is uniformly provided substantially in front of the portion corresponding to the roaster heating device in FIG. 4, the cooling efficiency is increased by increasing the size of the opening toward the top. Get better. Further, the opening may be provided only at the upper portion or at the upper left portion, but this may be determined and determined so that cooling can be efficiently performed depending on the model.
[0029]
Hereinafter, specific examples will be described.
[0030]
In an induction heating cooker having two induction heating units and one roaster unit, when the power consumption is increased by 20% from 4000 W to 4800 W, when the output is increased in the conventional configuration, the rear surface 31 of the main body outer shell is increased. Temperatures could exceed 85 ° C. This exceeds the temperature of 85 ° C. described in “Temperature Limit” in Appendix Table 4 of Schedule 8 of the Electrical Appliance and Material Safety Law. On the other hand, in the configuration of the present embodiment, when the space 34 was set to 10 mm and the output was increased by 20%, the temperature of the rear surface 31 of the outer shell of the main body was 80 ° C., which sufficiently satisfied the standard. As described above, according to the method of the present embodiment, a sufficient cooling effect can be obtained, and a space of about 10 mm can be absorbed inside the body, so that the embodiment can be performed without increasing the outer shape of the body. Further, even if it is necessary to enlarge the body, it can be practically about 2 to 3 mm, so that the outer dimensions of the body can be kept within the regulation value for installation.
[0031]
In the above description, the case where the interval between the spaces 34 is 10 mm has been described. However, the size may be further increased when there is a margin, or the temperature may be reduced to about 5 mm when there is no margin. The effect is almost unchanged. When the interval is smaller than 5 mm, the temperature reduction effect rapidly decreases. Therefore, in such a case, other means such as installing a new fan or the like to increase the wind power of the cooling wind is required.
[0032]
Further, in the present embodiment, the main body outer rear surface 31 and the partition wall 33 are provided substantially in parallel, but the distance between the main body outer rear surface 31 and the partition wall 33 near the inlet 36 provided in the inner partition wall 35 is increased. However, it is preferable that the cooling air be spread farther to the far side and the temperature distribution on the rear surface 31 of the main body outer shell be reduced, as the distance from the inlet 36 becomes smaller.
[0033]
In the present embodiment, the case where the space is vertically surrounded and the surroundings are described.However, the present invention is not limited to this, and depending on the design, there is little possibility that cooling air that has cooled the roaster heating device may enter from the surroundings. When there is no temperature limit, or when there is a margin for the temperature limit and a part of the cooling air may leak from the surroundings or from above and below, there is no need to stick to the configuration of the present embodiment. In short, any configuration of the space is possible as long as the cooling air is introduced into the provided space and the rear surface of the main body shell, which is the main point of the present embodiment, is sufficiently cooled.
[0034]
In addition, the introduction of the cooling air into the space is not limited to the above-described configuration, and any ventilation path may be provided as long as the cooling air that meets the gist of the present embodiment can be introduced. Of course.
[0035]
In this embodiment, the case where cooling air is introduced into the space has been described. However, depending on the design or the rate of increase in output is low, for example, about 10%, or when power consumption is low, If it is not necessary to reduce the temperature of the cooling air so much, a configuration in which cooling air is not introduced may be adopted. In this case, since the configuration is simplified, the temperature of the rear surface of the outer shell of the main body can be lowered without increasing the price.
[0036]
Further, even if a heat insulating material is inserted into the space between the partition wall and the rear surface of the main unit outer shell, the temperature of the main unit outer rear surface can be reduced. The width of the heat insulating material may be smaller than the width of the space. When the cooling air is caused to flow through the gap generated at this time as in the present embodiment, the effect of reducing the temperature is increased. The heat insulating material is preferably made of a fiber having heat resistance such as glass fiber or silicon fiber. In particular, when a vacuum heat insulating material is used as the heat insulating material, the effect is large. That is because, when performing the same level of heat insulation as using other heat insulators using a vacuum heat insulator, the thickness of the heat insulator can be reduced and the width of the space can be reduced, and This is because when the width of the space is constant, the width of the gap after the heat insulating material is inserted becomes large, and when a method of introducing the cooling air is used, the cooling air is easily flown. In addition, there is a method of filling a hollow space with an inorganic hollow body as a heat insulating material.
[0037]
In addition, if a heat ray reflective layer is provided inside the partition wall, that is, on the high-temperature side surface where the roaster heating device is located, radiation from the roaster heating device will be reflected and the temperature of the partition wall will be suppressed, and radiation from the partition wall will be reduced. The temperature can be lowered. Similarly, if the heat ray reflective layer is provided on the surface of the rear surface of the main body facing the partition wall, the temperature of the rear surface of the main body can be reduced for the same reason.
[0038]
The temperature reduction effect can be obtained with or without cooling air flowing through the space, but it is needless to say that flowing cooling air is more effective. Although there are various types of heat ray reflective layers, it is advantageous in terms of cost to laminate an aluminum foil on the partition wall or the rear surface of the outer shell of the main body, or to provide a coating film containing aluminum. The heat ray reflective layer may be provided on both the rear surface of the outer shell of the main body and the partition plate.
[0039]
In addition, in the conventional induction heating cooker, the temperature of the rear surface of the main body outer shell is not so much a problem, and the rear surface of the main body outer shell is hard to be seen by a human, so that it is common to use a sheet metal as it is. However, when it is necessary to reduce the temperature of the rear surface of the main body shell as in the present invention, if a radiation layer is provided outside the rear surface of the main body shell, radiation from the rear surface of the main body shell increases, and the temperature can be reduced. It should be noted that a coating film as the radiation layer can sufficiently exert its effect.
[0040]
In addition, the means of inserting a heat insulating material into the space, providing a heat ray reflective layer on the rear surface or partition wall of the main body outer shell, or providing a radiation layer on the rear surface of the main body outer shell may be used alone or in combination. Further, a temperature reduction effect can be obtained.
[0041]

FIG. 5 is a cross-sectional view of a main part of an induction heating cooker according to a second embodiment of the present invention, and FIG. 6 is a cross-sectional view of a main part of another example of the induction heating cooker. Note that the basic configuration of the present embodiment is the same as that of the first embodiment, and therefore the description will focus on the differences. The same functions as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.
[0042]
This embodiment is different from the first embodiment in that when the first embodiment introduces the cooling air into the space 34, the cooling air generated by the cooling fan 29 is forcibly introduced from the introduction port 36 of the inner partition wall 35 and cooled. On the other hand, in the present embodiment, the inlet is not provided in the inner partition wall 35, and cooling is performed by natural convection performed by upper and lower openings provided in the rear surface 31 of the main body.
[0043]
In FIG. 5, the outside air that has entered the space 34 formed between the partition wall 33 and the rear surface 31 of the main body through the lower opening 37 passes through the space 34 and is discharged outside through the upper opening 38. In the course of the natural convection, heat is taken from the partition wall 33 to cool the partition wall 33 and reduce the radiant temperature. In addition, since the outside air comes into contact with the rear surface 31 of the main body and cools, the temperature can be suppressed from rising. .
[0044]
FIG. 6 shows that the lower opening 37 and the upper opening 38 are provided with cut-and-raised portions 39, whereby natural convection is further promoted. The cut-and-raised portion 39 of the upper opening 38 may be directed downward, or may not be provided.
[0045]
The upper opening 38 may be received at the top of the space 34. At this time, it is necessary to secure an exhaust path to the outside. Further, the same effect as in the first embodiment can be obtained by inserting a heat insulating material in the space, providing a heat reflection layer or a radiation layer, or using a combination thereof as in the first embodiment. .
[0046]
As described above, according to the present embodiment, the temperature of the rear surface of the outer shell of the main body can be reduced with a simple configuration.
[0047]
As described above, in the first and second embodiments, the induction heating cooker having the two-port induction heating unit and the one roaster unit has been described as the induction heating cooker. However, the present invention is not limited to this. And an induction heating cooker having one radiant heating section and one roaster section, or an induction heating cooker having one roaster section and one or more other heating sections. Of course it is good.
[0048]
Further, according to the present embodiment, a space is provided between the rear surface of the main body outer shell and the partition wall, cooling air is introduced into this space, a heat insulating material is inserted, or a heat reflection layer or a radiation layer is provided. , And by using them in combination, the temperature of the rear surface of the outer shell of the main body can be reduced according to each means. Therefore, since the temperature reduction ratio varies depending on the means, the temperature reduction ratio may be determined based on the magnitude of power consumption, the rate of increase in power consumption, or the required reduction temperature.
[0049]
As described above, according to the present embodiment, the temperature of the rear surface of the outer shell of the main body can be reduced with a simple configuration and almost without increasing the external dimensions.
[0050]
【The invention's effect】
As described above, according to the first to eighth aspects of the present invention, the rear surface of the main body shell located behind the roaster heating device is not directly exposed to the high-temperature exhaust gas that has cooled the roaster heating device. Reduction can be achieved.
