Description

本発明は、ガラス等の熱線を透過する材質の天板を用いたフラットタイプのガスコンロに関する。   The present invention relates to a flat type gas stove using a top plate made of a material that transmits heat rays such as glass.

従来、ガラス製の天板の下側に、表面燃焼式のバーナを該バーナの燃焼面が天板に対向するように配置し、天板上に載置した被加熱物をバーナの燃焼面からの輻射熱で加熱するようにしたフラットタイプのガスコンロが知られている(例えば、特許文献１参照。)。尚、このものでは、天板の下側に、バーナの燃焼排ガスを天板の後方に導く排気通路を設け、排気通路の下流端から燃焼排ガスを外部に排出している。
特開平７−５５１５１号公報 Conventionally, a surface combustion type burner is arranged below the glass top plate so that the combustion surface of the burner faces the top plate, and the object to be heated placed on the top plate is removed from the combustion surface of the burner. There is known a flat type gas stove that is heated by radiant heat (see, for example, Patent Document 1). In this case, an exhaust passage for guiding the combustion exhaust gas of the burner to the rear of the top plate is provided below the top plate, and the combustion exhaust gas is discharged to the outside from the downstream end of the exhaust passage.
JP-A-7-55151

上記ガスコンロは、天板にバーナを臨ませる開口を形成せずに済み、天板がフラットになって、外観性および清掃性が向上する利点がある。然し、バーナの燃焼排ガスは被加熱物の加熱に殆ど寄与せずに高温のまま大気中に放出され、熱効率が悪くなる。   The gas stove does not need to form an opening for allowing the burner to face the top plate, and the top plate is flat, so that there is an advantage that appearance and cleaning properties are improved. However, the combustion exhaust gas of the burner hardly releases the heating of the object to be heated and is released into the atmosphere at a high temperature, resulting in poor thermal efficiency.

本発明は、以上の点に鑑み、熱効率を向上し得るようにしたフラットタイプのガスコンロを提供することをその課題としている。   This invention makes it the subject to provide the flat type gas stove which enabled it to improve thermal efficiency in view of the above point.

上記課題を解決するために、本発明では、熱線を透過する材質の天板の下側に、表面燃焼式のバーナを該バーナの燃焼面を天板に向けた状態で配置し、天板上に載置した被加熱物をバーナの燃焼面からの輻射熱で加熱するようにしたコンロにおいて、天板に、バーナの直上部から離れた部分に位置させて、バーナの燃焼排ガスを排出する排気口を開設し、前記被加熱物とは別の被加熱物をこの排気口の上方に位置させて支持可能な五徳を設けている。   In order to solve the above-mentioned problems, in the present invention, a surface combustion type burner is disposed below the top plate made of a material that transmits heat rays, with the combustion surface of the burner facing the top plate, In the stove where the object to be heated is heated by the radiant heat from the combustion surface of the burner, the exhaust is placed on the top plate at a position away from the upper part of the burner and discharges the combustion exhaust gas of the burner Is provided, and a virtues capable of supporting the object to be heated, which is different from the object to be heated, above the exhaust port are provided.

上記の構成によれば、バーナの直上部に位置する天板の部分に載置した被加熱物をバーナの燃焼面からの輻射熱で加熱すると共に、排気口の上方位置に五徳によって支持される被加熱物をバーナの燃焼排ガスで加熱することができる。そのため、高温の燃焼排ガスをそのまま大気中に放出する従来のフラットタイプのガスコンロに比し、コンロ全体の熱効率が向上する。   According to the above configuration, the object to be heated placed on the top plate located directly above the burner is heated by the radiant heat from the combustion surface of the burner, and the object supported by the five virtues above the exhaust port. The heated object can be heated with the combustion exhaust gas of the burner. Therefore, compared with the conventional flat type gas stove which discharges high-temperature combustion exhaust gas as it is in the atmosphere, the thermal efficiency of the entire stove is improved.

図１は、システムキッチンのカウンタトップＣＴに組み込まれるフラットタイプのドロップイン式ガスコンロを示している。このガスコンロは、熱線を透過する材質、例えば、セラミックガラス等の耐熱ガラス製の天板１を備えている。尚、天板１の周辺には、金属製の外枠２が装着されている。   FIG. 1 shows a flat type drop-in gas stove incorporated in a countertop CT of a system kitchen. The gas stove includes a top plate 1 made of a material that transmits heat rays, for example, heat-resistant glass such as ceramic glass. A metal outer frame 2 is mounted around the top plate 1.

天板１の下側には、左右一対のバーナ３，３が配置されている。各バーナ３は、図２に示すように、セラミックファイバの積層体や多孔のセラミックプレートで構成される燃焼面３ａを有する表面燃焼式バーナであり、燃料ガスと一次空気との混合気を燃焼面３ａ上で燃焼させるように構成されている。そして、コンロ本体４に、天板１の下面に対し隙間を存して対向する支持板５を設け、この支持板５の下面に、各バーナ３をその燃焼面３ａが支持板５に形成した窓穴を通して天板１に対向するように取り付けている。   A pair of left and right burners 3 and 3 are disposed below the top plate 1. As shown in FIG. 2, each burner 3 is a surface combustion type burner having a combustion surface 3a composed of a laminate of ceramic fibers or a porous ceramic plate, and a mixture of fuel gas and primary air is burned into the combustion surface. It is comprised so that it may burn on 3a. The stove body 4 is provided with a support plate 5 that faces the lower surface of the top plate 1 with a gap, and each burner 3 is formed on the support plate 5 on the lower surface of the support plate 5 with its combustion surface 3a. It is attached so as to face the top plate 1 through the window hole.

各バーナ３の直上部から離れた天板１の後部中央には排気口６が開設されている。そして、支持板５上に断熱材製の排気ダクト７を設け、この排気ダクト７により、各バーナ３の燃焼排ガスを排気口６に導く排気通路８を天板１との間に画成している。尚、左右のバーナ３，３の排気通路８，８は下流端で合流して共通の排気口６に連通している。   An exhaust port 6 is opened in the center of the rear part of the top plate 1 that is away from the upper part of each burner 3. An exhaust duct 7 made of a heat insulating material is provided on the support plate 5, and an exhaust passage 8 that guides the combustion exhaust gas of each burner 3 to the exhaust port 6 is defined between the support plate 5 and the top plate 1. Yes. The exhaust passages 8 and 8 of the left and right burners 3 and 3 merge at the downstream end and communicate with the common exhaust port 6.

また、天板１上には、排気口６を囲うようにして五徳９が設けられている。かくして、バーナ３の直上部に位置する天板１の部分に載置する鍋等の被加熱物Ｐ１とは別の被加熱物Ｐ２を排気口６の上方位置に五徳９によって支持可能となる。尚、五徳９は、天板１の排気口６の周辺部に一体成形した放射状の複数の突条９ａで構成されている。   Further, on the top plate 1, a virtue 9 is provided so as to surround the exhaust port 6. Thus, the object to be heated P2 different from the object to be heated P1 such as a pan placed on the top plate 1 located immediately above the burner 3 can be supported by the five virtues 9 above the exhaust port 6. The virtues 9 are constituted by a plurality of radial ridges 9a integrally formed around the exhaust port 6 of the top plate 1.

以上の構成によれば、バーナ３を燃焼させると、バーナ３の燃焼面３ａが赤熱し、燃焼面３ａからの輻射熱が天板１を透過して天板１上の被加熱物Ｐ１に及び、被加熱物Ｐ１が加熱される。尚、バーナ３の燃焼排ガスの熱で天板１が加熱され、天板１を介しての熱伝導によっても被加熱物Ｐ１が加熱されるが、天板１を介しての熱伝導効率は左程良くなく、被加熱物Ｐ１は主として燃焼面３ａからの輻射熱で加熱される。このように、燃焼排ガスの熱は被加熱物Ｐ１の加熱には左程寄与しないが、排気口６から排出される燃焼排ガスにより五徳９上の被加熱物Ｐ２が加熱されるため、燃焼排ガスの熱を有効利用でき、コンロ全体の熱効率が向上する。   According to the above configuration, when the burner 3 is burned, the combustion surface 3a of the burner 3 is red hot, and the radiant heat from the combustion surface 3a passes through the top plate 1 and reaches the object P1 to be heated on the top plate 1. The article P1 to be heated is heated. The top plate 1 is heated by the heat of the combustion exhaust gas from the burner 3, and the object P1 is also heated by heat conduction through the top plate 1, but the heat conduction efficiency through the top plate 1 is left. The object to be heated P1 is mainly heated by the radiant heat from the combustion surface 3a. Thus, the heat of the combustion exhaust gas does not contribute to the heating of the object P1 to the left, but the object P2 on the virtues 9 is heated by the combustion exhaust gas discharged from the exhaust port 6, so that the combustion exhaust gas Heat can be used effectively, improving the overall heat efficiency of the stove.

ところで、上記実施形態では、天板１の後部中央に左右のバーナ３，３の燃焼排ガスを合流して排出する単一の排気口６を設けたが、これに限るものではない。例えば、図３に示すように、天板１の後部に左右のバーナ３，３に対応する左右の排気口６，６を開設し、各バーナ３の燃焼排ガスを各別の排気口６から排出するようにしても良い。また、上記実施形態では、五徳９を天板１に一体成形した複数の突条９ａで構成しているが、天板１と別体の五徳を設けても良い。更に、上記実施形態では、五徳９が排気口６を囲うように配置されているが、図３に示すように、排気口６を覆う網状の五徳９を用いても良い。   By the way, in the said embodiment, although the single exhaust port 6 which merges and discharge | emits the combustion exhaust gas of the left and right burners 3 and 3 was provided in the center of the rear part of the top plate 1, it is not restricted to this. For example, as shown in FIG. 3, left and right exhaust ports 6, 6 corresponding to the left and right burners 3, 3 are opened at the rear of the top board 1, and the combustion exhaust gas of each burner 3 is discharged from each separate exhaust port 6. You may make it do. Moreover, in the said embodiment, although the virtues 9 are comprised with the some protrusion 9a integrally molded to the top plate 1, you may provide the 5 virtues separate from the top plate 1. FIG. Furthermore, in the said embodiment, although the virtues 9 are arrange | positioned so that the exhaust port 6 may be enclosed, you may use the net-like virtues 9 which cover the exhaust port 6, as shown in FIG.

また、本発明は上記したドロップイン式ガスコンロに限らず、フラットタイプの卓上式ガスコンロにも勿論適用できる。   Further, the present invention is not limited to the above-described drop-in type gas stove but can be applied to a flat type table type gas stove.
