Description

【0001】
【発明の属する技術分野】
本発明は家庭で用いられる誘導加熱調理器に関し、特に、トッププレートの上面に光による模様を描く発光手段を有するものに関する。
【0002】
【従来の技術】
誘導加熱調理器は加熱コイルに高周波電流を流し、高周波磁界を発生させ、加熱コイルと磁気結合している鍋(負荷)に渦電流によるジュール熱を発生させ、鍋自体を発熱させて調理を行う調理器である。そのため炎が見えるガス調理器や加熱部が赤熱する電気ヒータと違い加熱部を視覚的に捉えることが出来ないという問題があった。
【0003】
この課題を解決するために、(例えば、特許文献1参照)に記載されているようなものがあった。図8は、前記公報に記載された従来の誘導加熱調理器の断面を示すものである。図8において、1は外郭を構成する本体であり、2は本体の上部に設けたトッププレートである。3はトッププレート2に載置された鍋などの被加熱物であり、誘導加熱により発熱し内部に収納した調理物を加熱する。4はトッププレート2の下部に設けられた被加熱物3を誘導加熱する加熱コイルである。
【0004】
また、5は発光手段であり、光源6と導光体7とより構成され、発光面8よりトッププレート2に向かって光を放射する。9は加熱コイルや発光手段を制御する制御手段である。
【0005】
前記構成において加熱コイル4が通電されると被加熱物3は誘導加熱により加熱される。それと同時に、光源6が点灯し、その光は導光体7を導光し発光面8より発光しトッププレート2を照射する。これによりトッププレート2の面上に図9に示すような円環状の模様が描かれ、加熱部を視覚的に捉える事ができるというものであった。
【0006】
【特許文献1】
特開2001−160483号公報
【0007】
【発明が解決しようとする課題】
しかしながら、前記従来の構成では、図10に示すように、扇状の導光体片7aと扇状の様に設けた光源6とで発光体の1ブロックとし、これらのブロックを組合わせて円環状の発光手段5を作製していた。そのため、発光手段を作製するにあたって多数のブロックを組合わせたり、狭い空間で光源6を結線したりしなければならず部品が多くなると共に製造工数がかかるという問題があった。
【0008】
また、図8に示すように加熱コイル4の下側に導光体7が配置されているため、冷却風の流れが遮断され加熱コイル4が冷却され難いという問題があった。そのため、本発明に先立って、図11に示すように光源6と円環状の導光体10とからなる発光手段を提案した。この構成では加熱コイル4の下部に導光体10がなく、冷却風が直接加熱コイル4にあたるため加熱コイル4の冷却が良く、かつ部品点数が少ないため組立て工数を低減できるという利点を有していた。
【0009】
しかしながら、前記構成では発光手段の耐熱温度が低いため、被加熱物3がズレた状態での空焼きや、長時間の揚げ物調理に使用された場合など、被加熱物3からの熱の影響が発光面8に及び、導光体10の耐熱温度以上に温度が上昇してしまい変形や変色などが生じる可能性があるため、トッププレート2と導光体10の発光面8との間に空間距離11を確保する必要があった。そのため、導光体10に入光する光源6の輝度、光量は非常に大きいものを使用しなければならず、また、本体内に高さ方向のスペースを占有してしまい厚みが厚くなるという問題があった。
【0010】
本発明は、前記従来の課題を解決するもので、簡単な構成で、加熱コイル周辺に発光手段の載置スペースを確保しつつ、低輝度・少光量の光源を使用してもトッププレート上では充分な視認性を備え、また本体外郭の高さ方向をコンパクトに設計することのできる発光手段を備え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、外郭を構成する本体と、前記本体の上面に設けた被加熱物を載置する加熱部を有するトッププレートと、前記トッププレートの下方に設けた前記被加熱物を誘導加熱する加熱コイルと、前記加熱コイルの外周部の少なくとも一部に設けた発光手段と前記発光手段に光を照射する光源を備え、前記発光手段は、前記トッププレートに設けるようにするとともに、前記トッププレートの被加熱物を載置する面とは反対側に前記加熱コイルよりも外側に放射状に凸部を形成してなる構成とした。
【0012】
この構成により、耐熱温度と透光性を充分確保しているトッププレートと一体となるため変形・変色や、光の損失などの心配がなく、高さ方向のスペースを有効に使い薄型の誘導加熱調理器を得ることができる。
【0013】
また、被加熱物の側面底部に炎のような模様が形成されるとともに、円環状の模様ではなく、直線形状で被加熱物の載置位置を視覚的に捉えることができる。
【0014】
【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被加熱物を載置する加熱部を有するトッププレートと、前記トッププレートの下方に設けた前記被加熱物を誘導加熱する加熱コイルと、前記加熱コイルの外周部の少なくとも一部に設けた発光手段と前記発光手段に光を照射する光源を備え、前記発光手段は、前記トッププレートに設けるようにするとともに、前記トッププレートの被加熱物を載置する面とは反対側に前記加熱コイルよりも外側に放射状に凸部を形成してなる構成とした。この構成により耐熱温度の高いトッププレートと発光手段が一体となり、従来設けていたトッププレートと発光手段との空間距離が不必要になり高さ方向の制約を受けることなく非常に光の損失が少ないコンパクト設計を可能にすることができる。
【0015】
また、被加熱物の側面底部に炎のような模様が形成されるとともに、円環状の模様ではなく、直線形状で被加熱物の載置位置を視覚的に捉えることができる。
【0016】
【実施例】
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。
【0017】
図1は本発明の誘導加熱調理器の外観斜視図、図2は図1のトッププレートを外し、裏面側(加熱コイル側)から見た発光手段の外観斜視図、図3は図2のB−B線断面図、図4は図1のA−A線断面図である。なお、本実施例の誘導加熱調理器の基本構成は従来例とほぼ同じなので基本構成の説明は省略し、従来例とは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。
【0018】
先ず、本実施例に用いるトッププレートと発光手段について図2および図3を用いて説明する。図3において、トッププレート22は透光性の耐熱ガラス23の裏面に印刷により半透明の膜24を設けた構成になっている。これは外部から本体21の内部が見えないようにするためである。本実施例の特徴は、このような構成のトッププレート22において加熱コイル側に透光性の凸部25を設ける構成とした点である。前記凸部25は、断面が四辺形である円環状の導光体26により構成されており、光源27と共に発光手段28を構成している。
【0019】
また、導光体26である凸部25には光を取入れる入光部29を設けている。そして、光源27からの光は入光部29より入光し導光体26である凸部25の内部を図の矢印の方向に伝播していく。
【0020】
また、図3に示すように導光体26である凸部25の突出面には光反射層30が設けられ、導光体中を伝播する光が光反射層30で反射し、トッププレート22を介して外部に放射する発光面31が設けられている。光反射層30はシリコン樹脂などの不透光性材料で高反射率を備えた塗装、接着剤、粘着テープの貼り付けあるいは凹凸の形成などの簡単な方法により設けることができる。また、発光面31にシボ加工を施すと輝度が高くなる。
【0021】
本実施例では光源27を2個設け左右の入光部29より導光体26である凸部25に入光している。したがって、入光した光は導光体26中を右回りと左回りの両方向に進む。そのため、各部分の輝度は両方向の光の和となるため、各部分の輝度はほぼ等しくなる。
【0022】
次に、前記発光手段28を用いた誘導加熱調理器の内部構成について図4を用いて説明する。32は加熱コイル4を載置するコイル保持台であり、底部は冷却風が加熱コイル4に直接当たるように大きな空間を設けている。また凸部25からの光を遮光するために遮光性の側壁を設けている。また加熱コイル4とコイル保持台32の側壁との間に前記で説明したトッププレートに設けた凸部25である断面が矩形の環状導光体26である発光手段28が位置するようになる。
【0023】
凸部の外表面は入光部29を除いて図5に示すように光を反射する耐熱性の膜24を設けても良い。そうすることで、入光部の光を凸部の外への発光ロスを低減する事ができる。
【0024】
以上述べたように本実施例によれば、トッププレートと発光手段を一体とする事により簡単な構成で、加熱コイル周辺に発光手段の載置スペースを確保しつつ、低輝度・少光量の光源を使用してもトッププレート上でも充分な視認性と、光量の損失を最小限に抑え、トッププレートと発光面の間に空間距離を必要とせず、本体外郭の高さ方向をコンパクトに設計することのできる誘導加熱調理器を提供することができる。
【0025】
なお、本実施例ではトッププレートと発光手段を一体となる場合について説明したが、光の透過性が良く耐熱温度の高いものであれば、空間距離を最小にすることで同様の効果が得られるものである。
【0026】
また、本実施例では導光体として環状の導光体を用いた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任意の形状の導光体を用いることにより、トッププレート上に任意の図形を描くことができるのは勿論であり、導光体の断面も四辺形に限定されるものではない。
【0027】
また、本実施例のその他の例を図6および図7に示す。特に図7における加熱コイルよりも外側に放射状に凸部を形成してなるものについては、円環状ではなくても、簡単な構成で被加熱物の載置位置を明確にすることができる。また、光源部を加熱コイルから離れた位置に設けることもできるので光源の耐熱温度の制約を受けることもない。
【0028】
また、本実施例では光源収納部を1箇所に設けた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、導光体の長さが長く多くの光源を必要とする場合は、必要に応じて数箇所に設けてもよいのはもちろんである。
【0029】
また、本実施例ではコイル保持台に遮光性の側壁を設けた場合について説明したが、導光体の側面から光が漏洩することが許容される場合は、側壁を遮光性にする必要はなく、また、側壁を必ずしも設ける必要はない。
【0030】
また、本実施例では、入光部に光源部の光が照射する方向をトッププレートの被加熱物を載置する面と平行である場合について説明したが、発光する部位やスペースの関係上入光部に光源部の光を照射する方向をトッププレートの被加熱物を載置する面と垂直とすることも可能であり、この場合光源部の耐熱温度の制約を受けにくくなり平面方向のスペースを有効に使用することができる。
【0031】
以上述べたように本実施例はトッププレートに発光手段を設けて本体内部の空間を効率よく利用し、薄型の誘導加熱調理器を得ることを目的としたものであり、この目的を達成するものであれば前記構成に限定されるものではない。
【0032】
【発明の効果】
以上のように、請求項1に記載の発明によれば、簡単な構成で、構成部品を減らし、本体内部での発光ロスの少ない薄型の誘導加熱調理器を提供することができる。
【0033】
また、被加熱物の側面底部に炎のような模様が形成されるとともに、円環状の模様ではなく、直線形状で被加熱物の載置位置を視覚的に捉えることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an induction heating cooker used at home, and more particularly to a device having a light emitting means for drawing a pattern by light on the upper surface of a top plate.
[0002]
[Prior art]
The induction heating cooker applies high-frequency current to the heating coil, generates a high-frequency magnetic field, generates Joule heat due to eddy current in the pan (load) magnetically coupled to the heating coil, and heats the pan itself for cooking. It is a cooker. Therefore, there is a problem that the heating part cannot be visually grasped unlike a gas cooker in which a flame is visible and an electric heater in which the heating part is red hot.
[0003]
In order to solve this problem, there has been one described in (for example, see Patent Document 1). FIG. 8 shows a cross section of a conventional induction heating cooker described in the publication. In FIG. 8, 1 is a main body constituting the outer shell, and 2 is a top plate provided on the upper portion of the main body. Reference numeral 3 denotes an object to be heated such as a pan placed on the top plate 2, which generates heat by induction heating and heats the food stored inside. Reference numeral 4 denotes a heating coil that induction-heats the object to be heated 3 provided at the lower portion of the top plate 2.
[0004]
Reference numeral 5 denotes a light emitting means, which includes a light source 6 and a light guide 7 and emits light from the light emitting surface 8 toward the top plate 2. Reference numeral 9 denotes control means for controlling the heating coil and the light emitting means.
[0005]
In the above configuration, when the heating coil 4 is energized, the article 3 to be heated is heated by induction heating. At the same time, the light source 6 is turned on, and the light is guided through the light guide 7 and emitted from the light emitting surface 8 to irradiate the top plate 2. As a result, an annular pattern as shown in FIG. 9 is drawn on the surface of the top plate 2 so that the heating portion can be visually grasped.
[0006]
[Patent Document 1]
Japanese Patent Laid-Open No. 2001-160483
[Problems to be solved by the invention]
However, in the conventional configuration, as shown in FIG. 10, a fan-shaped light guide piece 7a and a light source 6 provided like a fan form one block of a light emitter, and these blocks are combined to form an annular shape. The light emitting means 5 was produced. For this reason, when manufacturing the light emitting means, it is necessary to combine a large number of blocks or to connect the light source 6 in a narrow space.
[0008]
Further, since the light guide 7 is disposed below the heating coil 4 as shown in FIG. 8, there is a problem that the flow of the cooling air is blocked and the heating coil 4 is difficult to cool. Therefore, prior to the present invention, a light emitting means comprising a light source 6 and an annular light guide 10 was proposed as shown in FIG. In this configuration, there is no light guide 10 under the heating coil 4, and the cooling air is directly applied to the heating coil 4, so that the heating coil 4 is cooled well and the number of parts is small, so that the number of assembling steps can be reduced. It was.
[0009]
However, since the heat-resistant temperature of the light emitting means is low in the above configuration, the influence of heat from the object to be heated 3 is affected, for example, when the object to be heated 3 is baked in a misaligned state or used for cooking fried food for a long time. Since the temperature rises over the light emitting surface 8 and exceeds the heat resistance temperature of the light guide 10, there is a possibility that deformation, discoloration, and the like occur, so that there is a space between the top plate 2 and the light emitting surface 8 of the light guide 10. It was necessary to secure a distance of 11. For this reason, the light source 6 that enters the light guide 10 must have a very large luminance and light quantity, and also occupies a space in the height direction in the main body, resulting in an increase in thickness. was there.
[0010]
The present invention solves the above-mentioned conventional problems, and with a simple configuration, while securing a mounting space for the light emitting means around the heating coil, even if a low-luminance, low-light source is used, It is an object of the present invention to provide an induction heating cooker provided with light emitting means that has sufficient visibility and can be designed in a compact manner in the height direction of the outer shell of the main body.
[0011]
[Means for Solving the Problems]
In order to solve the conventional problems, an induction heating cooker according to the present invention includes a main body constituting an outer shell, a top plate having a heating unit on which an object to be heated provided on the upper surface of the main body is placed, and the top comprising a heating coil for induction heating the object to be heated provided below the plate, a light source for irradiating light to the light emitting means and the light emitting means provided in at least part of the outer periphery of the heating coil, wherein the light emitting means The top plate is provided with a convex portion radially formed outside the heating coil on the opposite side of the top plate from the surface on which the object to be heated is placed .
[0012]
With this configuration, it is integrated with a top plate that has sufficient heat resistance and translucency, so there is no risk of deformation, discoloration, loss of light, etc., and thin induction heating that effectively uses space in the height direction. You can get a cooker.
[0013]
In addition, a flame-like pattern is formed on the bottom of the side surface of the object to be heated, and it is possible to visually grasp the placement position of the object to be heated in a linear shape instead of an annular pattern.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 is a main body constituting an outer shell, a top plate having a heating portion on which an object to be heated provided on the upper surface of the main body is placed, and the object to be heated provided below the top plate. a heating coil for induction heating, and includes a light source for irradiating light to the light emitting means and the light emitting means provided in at least part of the outer periphery of the heating coil, wherein the light emitting means is configured to be provided on the top plate The top plate has a configuration in which convex portions are radially formed outside the heating coil on the side opposite to the surface on which the object to be heated is placed . With this configuration, the top plate having a high heat resistance temperature and the light emitting means are integrated, and the spatial distance between the conventionally provided top plate and the light emitting means becomes unnecessary, and there is very little light loss without being restricted in the height direction. A compact design can be made possible.
[0015]
In addition , a flame-like pattern is formed on the bottom of the side surface of the object to be heated, and it is possible to visually grasp the placement position of the object to be heated in a linear shape instead of an annular pattern.
[0016]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0017]
1 is an external perspective view of the induction heating cooker of the present invention, FIG. 2 is an external perspective view of the light emitting means viewed from the back side (heating coil side) with the top plate of FIG. 1 removed, and FIG. FIG. 4 is a cross-sectional view taken along line -B, and FIG. 4 is a cross-sectional view taken along line AA in FIG. In addition, since the basic composition of the induction heating cooking appliance of a present Example is as substantially the same as a prior art example, description of a basic structure is abbreviate | omitted and it demonstrates centering on a different point from a prior art example. The same functions as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0018]
First, the top plate and light emitting means used in this embodiment will be described with reference to FIGS. In FIG. 3, the top plate 22 has a configuration in which a translucent film 24 is provided on the back surface of a translucent heat-resistant glass 23 by printing. This is to prevent the inside of the main body 21 from being seen from the outside. The feature of the present embodiment is that the top plate 22 having such a configuration is provided with a translucent convex portion 25 on the heating coil side. The convex portion 25 is constituted by an annular light guide 26 having a quadrilateral cross section, and constitutes a light emitting means 28 together with a light source 27.
[0019]
Further, a light incident part 29 for taking in light is provided on the convex part 25 which is the light guide 26. Then, light from the light source 27 enters from the light incident portion 29 and propagates in the direction of the arrow in the figure through the inside of the convex portion 25 which is the light guide 26.
[0020]
As shown in FIG. 3, a light reflecting layer 30 is provided on the projecting surface of the convex portion 25 that is the light guide 26, and light propagating in the light guide is reflected by the light reflecting layer 30, and the top plate 22. A light-emitting surface 31 that radiates to the outside via is provided. The light reflecting layer 30 can be provided by a simple method such as coating with light-transmitting material such as silicon resin, high adhesiveness, adhesion of adhesive, adhesive tape, or formation of irregularities. In addition, when the light emitting surface 31 is textured, the luminance increases.
[0021]
In this embodiment, two light sources 27 are provided, and light is incident on the convex portion 25 which is the light guide 26 from the left and right light incident portions 29. Accordingly, the incident light travels in the clockwise direction and the counterclockwise direction in the light guide 26. Therefore, the luminance of each part is the sum of the light in both directions, so that the luminance of each part is substantially equal.
[0022]
Next, the internal configuration of the induction heating cooker using the light emitting means 28 will be described with reference to FIG. Reference numeral 32 denotes a coil holding table on which the heating coil 4 is mounted, and a large space is provided at the bottom so that the cooling air directly hits the heating coil 4. Further, a light-shielding side wall is provided to shield light from the convex portion 25. Further, between the heating coil 4 and the side wall of the coil holding base 32, the light emitting means 28, which is the annular light guide 26 having a rectangular section, which is the convex portion 25 provided on the top plate described above, is positioned.
[0023]
The outer surface of the convex portion may be provided with a heat resistant film 24 that reflects light as shown in FIG. By doing so, it is possible to reduce a light emission loss of light from the light incident part to the outside of the convex part.
[0024]
As described above, according to the present embodiment, a light source with a low luminance and a small amount of light can be obtained with a simple structure by integrating the top plate and the light emitting means, while securing a mounting space for the light emitting means around the heating coil. Designed to be compact enough for the height of the outer shell of the main body without the need for a spatial distance between the top plate and the light emitting surface. An induction heating cooker that can be provided can be provided.
[0025]
In this embodiment, the case where the top plate and the light emitting means are integrated has been described. However, if the light transmittance is good and the heat resistant temperature is high, the same effect can be obtained by minimizing the spatial distance. Is.
[0026]
Moreover, although the present Example demonstrated the case where the cyclic | annular light guide was used as a light guide, it is not limited to this, By using a light guide of arbitrary shapes, arbitrary on a top plate Of course, a figure can be drawn, and the cross section of the light guide is not limited to a quadrilateral.
[0027]
Other examples of this embodiment are shown in FIGS. In particular, in the case where the convex portions are formed radially outside the heating coil in FIG. 7, the placement position of the object to be heated can be clarified with a simple configuration even if it is not annular. Further, since the light source unit can be provided at a position away from the heating coil, there is no restriction on the heat resistant temperature of the light source.
[0028]
In the present embodiment, the case where the light source storage portion is provided at one place has been described. However, the present invention is not limited to this, and is necessary when the light guide is long and requires many light sources. Of course, it may be provided in several places.
[0029]
Further, in the present embodiment, the case where a light-shielding side wall is provided on the coil holding base has been described. However, when light leakage is permitted from the side surface of the light guide, it is not necessary to make the side wall light-shielding. Further, it is not always necessary to provide the side wall.
[0030]
In the present embodiment, the case in which the light incident direction of the light source unit is parallel to the surface of the top plate on which the object to be heated is placed has been described. It is also possible to make the direction of irradiating the light from the light source part perpendicular to the surface of the top plate on which the object to be heated is placed. Can be used effectively.
[0031]
As described above, the present embodiment is intended to obtain a thin induction heating cooker by providing a light emitting means on the top plate to efficiently use the space inside the main body, and achieve this purpose. If it is, it is not limited to the said structure.
[0032]
