Description

【0001】
【発明の属する技術分野】
この発明はガスレンジ等の加熱手段の上に鍋などの調理容器を載置して当該調理容器を加熱する際の放熱を防止する放熱防止具に関する。特に、ガスレンジ等の加熱手段の上に鍋などの調理容器を載置して当該調理容器を加熱する際に、燃焼ガスと輻射熱の拡散を防止し、省エネルギーに貢献できる放熱防止具に関する。
【0002】
【従来の技術】
従来、ガスレンジ等の加熱手段の上に鍋などの調理容器を載置して当該調理容器を加熱し、調理する際の放熱を防止する放熱防止具としては、加熱手段の火炎部、例えば、ガスバーナー部と調理容器(例えば、鍋)全体をカバーするものが知られている。しかし、これは汎用性が無いため、実際にはほとんど使用されていない。
【0003】
【発明が解決しようとする課題】
本発明は、ガスレンジ等の加熱調理器具の火炎部(例えば、ガスバーナー部)の周囲に配備される五徳と組み合わせて使用することが可能であり、あるいは、五徳と一体化して用いることができるようにして汎用性が高く、抵抗感なく使用できる放熱防止具を提供することを目的としている。
【0004】
【課題を解決するための手段】
前記課題を解決するため本発明が提案する放熱防止具は、加熱調理器具の火炎部(例えば、ガスバーナー部)の周囲に配備される五徳と組み合わされて使用されるものであって、前記五徳の外周に配備されて使用され、前記五徳の外周に配備された際の上端縁の高さ位置が、前記五徳の上端縁の高さ位置より低くなるように形成されている環状の放熱防止用遮蔽帯からなることを特徴とするものである。
【0005】
また、前記課題を解決するため本発明が提案する他の放熱防止具は、加熱調理器具の火炎部(例えば、ガスバーナー部)の周囲に配備される五徳と組み合わされて使用されるものであって、前記五徳の外周に配備される環状の放熱防止用遮蔽帯からなり、当該環状の放熱防止用遮蔽帯の上端縁に円周方向に所定の間隔を開けて、当該環状の放熱防止用遮蔽帯の上方向と直径方向内側とに向かって突出する突起部が複数個設けられており、当該環状の放熱防止用遮蔽帯が前記五徳の外周に配備された際に、前記突起部の上端縁の高さ位置が、前記五徳の上端縁の高さ位置より高くなるように形成されていることを特徴とするものである。
【0006】
ガスレンジ等の加熱調理器具の火炎部(例えば、ガスバーナー部)の周囲に配備される五徳の上に鍋などの調理容器を載置して当該調理容器を加熱し、調理する場合、燃焼ガスと輻射熱は調理容器を加熱する目的以外に、かなりの部分が周辺に拡散してしまう。このことは、前記の加熱調理器具、調理容器に隣接するものが加熱されることから理解できる。
従来から知られている放熱防止具は、この知見に基づいて、加熱調理器具、あるいは加熱調理器具の火炎部と、調理容器(例えば、鍋)の全体をカバーするようになっていた。
【0007】
しかし、前記のように調理容器を加熱して調理する場合、拡散する熱の大半は加熱器と容器とが接触する部分から発生するのである。本願発明者は、この点に注目して本願発明を完成させたものである。
【0008】
前述した本発明の放熱防止具をガスレンジ等の加熱調理器具の火炎部(例えば、ガスバーナー部)の周囲に配備される五徳の外側(すなわち、外周側)に配置することにより、あるいは、本発明の放熱防止具の内周壁を五徳の外周に接合して一体化しておくことによって、ガスレンジの上面において、加熱調理器具の火炎部(例えば、ガスバーナー部)と、調理容器(例えば、鍋)の底周辺をカバーすることができ、効率よく放熱防止効果を上げ、汎用性を有するものを提供できる。
【0009】
以下、添付図面を参照して本発明の好ましい実施例を説明する。
【0010】
【実施例1】
図1は、本発明の第一の実施形態における放熱防止具1が、加熱調理器具(例えば、ガスレンジ)の火炎部(例えば、ガスバーナー部5)の周囲に配備される五徳3の外周に配備され、五徳3と組み合わされて使用されている状態を表す平面図である。
【0011】
放熱防止具1は、五徳3の外周に配備されて使用され、五徳3の外周に配備された際の上端縁の高さ位置が、図2図示のように、五徳3の上端縁4の高さ位置より低くなるように形成されている環状の放熱防止用遮蔽帯2から構成されている。
【0012】
この図1、図2図示の実施形態の放熱防止具1によれば、放熱防止用遮蔽帯2が五徳3の外周に配備されて使用される際の放熱防止用遮蔽帯2の上端縁の高さ位置が、図2図示のように、五徳3の上端縁4の高さ位置より低くなっているので、五徳3の上に調理容器(例えば、鍋)が置かれ、ガスバーナー部5からの火炎を受けて加熱、調理が行われる際の燃焼ガスの排気スペースを確保することができる。
【0013】
このように、五徳3の上端縁4の高さ位置と、環状の放熱防止用遮蔽帯2の高さ位置との関係によって燃焼ガスの排気スペースを確保できるので、環状の放熱防止用遮蔽帯2の内径を、五徳3の外径と同等にして(例えば、同じにして)コンパクトな形態にして使用することができる。
【0014】
また、五徳3の外周側と、環状の放熱防止用遮蔽帯2の内壁面側とを接合し、五徳3と環状の放熱防止用遮蔽帯2とが一体化されて放熱防止具1が形成されているようにすることもできる。
【0015】
五徳3、環状の放熱防止用遮蔽帯2のそれぞれの高さは、前記のように、環状の放熱防止用遮蔽帯2が五徳3の外周に配備されて使用される際の放熱防止用遮蔽帯2の上端縁の高さ位置が、図2図示のように、五徳3の上端縁4の高さ位置より低くなることによって燃焼ガスの排気スペースを確保することができるものであればよいので、ガスバーナー部5の高さに応じて適宜調節できる。
【0016】
なお、環状の放熱防止用遮蔽帯2としては耐熱性部材からなる環状薄板を用いることができる。この際、環状の放熱防止用遮蔽帯2の内周壁面を鏡面にしておけば、効率のよい輻射熱の利用を図る上で有利である。
【0017】
【実施例2】
図3は、本発明の第二の実施形態における放熱防止具11が、加熱調理器具(例えば、ガスレンジ)の火炎部(例えば、ガスバーナー部5)の周囲に配備される五徳13の外周に配備され、五徳13と組み合わされて使用されている状態を表す平面図である。
【0018】
放熱防止具11は、五徳13の外周に配備される環状の放熱防止用遮蔽帯12からなり、環状の放熱防止用遮蔽帯12の上端縁に円周方向に所定の間隔を開けて、環状の放熱防止用遮蔽帯12の上方向と直径方向内側とに向かって突出する突起部16a、16b、16c、16dが複数個設けられており、この環状の放熱防止用遮蔽帯12が五徳13の外周に配備された際に、図4(a)図示のように、突起部16a、16b、16c、16dの上端縁の高さ位置が、五徳13の上端縁の高さ位置より高くなるように形成されているものである。
【0019】
この図3、図4図示の実施形態の放熱防止具11によれば、放熱防止用遮蔽帯12が五徳13の外周に配備されて使用される際の突起部16a〜16dの上端縁の高さ位置が、図4(a)図示のように、五徳13の上端縁の高さ位置より高くなっているが、突起部16a〜16dは、図4(a)、(b)図示のように、環状の放熱防止用遮蔽帯12の上端縁に円周方向に所定の間隔を開けて環状の放熱防止用遮蔽帯12の上方向と直径方向内側とに向かって突出する構造になっているので、五徳13の上に調理容器(例えば、鍋)が置かれ、ガスバーナー部5からの火炎を受けて加熱、調理が行われる際の燃焼ガスの排気スペースを確保することができる。
【0020】
例えば、図6、図7図示のように、環状の放熱防止用遮蔽帯12の内径より径の小さい鍋21、22が用いられている場合であっても、図8図示のように、放熱防止用遮蔽帯12の内径より径の大きい鍋23が用いられている場合であっても、突起部16a、16b、16c、16dが存在していることによって、それぞれ、図示のように排気スペースが確保される。
【0021】
複数の突起部が設けられる数、隣接する突起部と突起部との間の間隔は、環状の放熱防止用遮蔽帯12の径の大きさ等に応じた排気スペースを設ける大きさ、バランス、等に従って適宜定めることができる。
【0022】
なお、この突起部16a〜16dは、図4(a)、(b)図示の形態では、環状の放熱防止用遮蔽帯12の上端縁に固定的に取り付けられているが、図5(a)、(b)図示のように、環状の放熱防止用遮蔽帯12の上端縁に取り付け、取り外し可能なスペーサーとすることもできる。図5(a)、(b)図示のスペーサー17、18は、金属製で、環状の放熱防止用遮蔽帯12に取り付け、取り外しできるように、環状の放熱防止用遮蔽帯12の厚みに対応した溝部を中央に備えているものである。
【0023】
この実施例の形態でも五徳13の外周側と、環状の放熱防止用遮蔽帯12の内壁面側とを接合し、五徳13と環状の放熱防止用遮蔽帯12とが一体化されて放熱防止具11が形成されているようにすることができる。
【0024】
環状の放熱防止用遮蔽帯12としては耐熱性部材からなる環状薄板を用いることができる。この際、環状の放熱防止用遮蔽帯12の内周壁面を鏡面にしておけば、効率のよい輻射熱の利用を図る上で有利である。
【0025】
あらかじめ備え付けられているガスバーナー部5の直径が40mm、五徳13の外周径が195mmである市販のガスレンジを用いて、図3、図4(a)、(b)図示の形態の本発明の放熱防止具11(環状の放熱防止用遮蔽帯12の内周径:199mm、環状の放熱防止用遮蔽帯12の高さ:40mm、突起部16a〜16dが環状の放熱防止用遮蔽帯12の上端縁よりも上側に突出している高さ:6mm)を用いた場合と、用いない場合について実験を行った。外径180mmの図6図示の形態の鍋に等量の水を入れ、蓋をして、本発明の放熱防止具11を用いた場合と、用いない場合について実験を行ったところ、ガスレンジ上面から100mmの高さ位置における鍋の周辺にあたる部分の温度は、本発明の放熱防止具11を用いない場合80℃であったものが、用いた場合には100℃に上昇していた。この際、ガスバーナーの火力を最大にして実験を行ったところ、ガスレンジ上面から100mmの高さ位置における鍋の周辺にあたる部分の温度は、本発明の放熱防止具11を用いない場合106℃であったものが、用いた場合には151℃に上昇していた。
【0026】
また、火力に関しては、本発明の放熱防止具11を用いた場合、用いない場合に比較して20%〜40%程度向上することが確認できた。
【0027】
【発明の効果】
本発明の放熱防止具は、ガスレンジに既設されている五徳と組み合わせたり、一体化して用いることができるものであり、汎用性があって、抵抗感なく使用することができる。
【0028】
また、簡素な構造で、洗浄、取扱いが容易である。
【0029】
更に、ガスレンジ等の加熱調理器具の周囲への放熱を効果的に抑え、その一方、加熱効率を効果的に向上させることができる。例えば、本発明の放熱防止具を市販のガスレンジに配備されている五徳の外側に配置して使用するだけで、火力を20%〜40%程度向上させることができる。そこで、家庭用のガスレンジは火力が弱いために中華料理のように強い火力を必要とする料理には不向きのように考えられているが、本発明の放熱防止具を用いることにより、火力を向上させて、家庭用のガスレンジであっても、中華料理のように強い火力を必要とする調理に十分対応可能にすることができる。
【0030】
しかも、このような火力向上を使用燃料を増加させることなく達成できるので、使用する燃料の節減にも役立つものである。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat radiation preventing device for placing a cooking vessel such as a pot on a heating means such as a gas range and preventing heat radiation when heating the cooking vessel. In particular, the present invention relates to a radiation preventing device that can prevent combustion gas and radiant heat from diffusing when a cooking vessel such as a pan is placed on a heating means such as a gas range and heating the cooking vessel, thereby contributing to energy saving.
[0002]
[Prior art]
Conventionally, a cooking vessel such as a pot is placed on a heating means such as a gas range to heat the cooking vessel, and as a heat radiation preventing device for preventing heat radiation during cooking, a flame portion of the heating means, for example, It is known to cover a gas burner section and an entire cooking vessel (for example, a pan). However, since it is not versatile, it is rarely used in practice.
[0003]
[Problems to be solved by the invention]
INDUSTRIAL APPLICABILITY The present invention can be used in combination with a virtue provided around a flame portion (for example, a gas burner portion) of a cooking appliance such as a gas range, or can be used integrally with a virtue. It is an object of the present invention to provide a heat radiation preventing device which has high versatility and can be used without resistance.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a heat radiation prevention tool proposed by the present invention is used in combination with a virtue provided around a flame portion (for example, a gas burner portion) of a cooking device, An annular heat-preventing ring formed so that the height position of the upper edge when deployed on the outer circumference of the virtues is lower than the height position of the upper edge of the virtues. It is characterized by comprising a shielding band.
[0005]
Further, another heat-dissipating device proposed by the present invention to solve the above problem is used in combination with a virtue provided around a flame portion (for example, a gas burner portion) of a heating cooker. The annular heat radiation preventing shield band is provided on the outer periphery of the circumstance, and a predetermined interval is circumferentially provided at an upper end edge of the circular heat radiation preventing shielding band to form the annular heat radiation preventing shield.

[0006]
When a cooking vessel such as a pot is placed on a gorge provided around a flame section (for example, a gas burner section) of a heating cooker such as a gas stove and the cooking vessel is heated and cooked, combustion gas is used. In addition to the purpose of heating the cooking container, a considerable portion of the radiant heat diffuses to the periphery. This can be understood from the fact that the heating cooking utensil and the one adjacent to the cooking container are heated.
Based on this finding, conventionally known heat-dissipating devices cover the entirety of the cooking utensil or the flame portion of the heating utensil and the entire cooking container (eg, pan).
[0007]
However, when the cooking container is heated and cooked as described above, most of the diffused heat is generated from a portion where the heater contacts the container. The present inventor has completed the present invention by paying attention to this point.
[0008]
By disposing the above-mentioned heat radiation preventing device of the present invention outside (i.e., the outer peripheral side) of a virtue provided around a flame portion (for example, a gas burner portion) of a cooking device such as a gas range, or By joining the inner peripheral wall of the heat radiation preventing device of the present invention to the outer periphery of the virtue and integrating the inner peripheral wall, a flame portion (for example, a gas burner portion) of a cooking device and a cooking container (for example, a pan) are provided on the upper surface of the gas range. ) Can be covered, and the heat radiation preventing effect can be efficiently increased, and a versatile product can be provided.

[0023]
Also in this embodiment, the outer peripheral side of the virtues 13 and the inner wall surface of the annular heat radiation preventing shielding band 12 are joined, and the virtues 13 and the circular heat radiation preventing shielding band 12 are integrated to form a heat radiation preventing device. 11 can be formed.
[0024]
An annular thin plate made of a heat-resistant member can be used as the annular heat-dissipating shielding band 12. At this time, if the inner peripheral wall surface of the annular heat radiation prevention shielding band 12 is made to be a mirror surface, it is advantageous for efficient use of radiant heat.
[0025]
Using a commercially available gas range in which the diameter of the gas burner portion 5 provided in advance is 40 mm and the outer diameter of the virtues 13 is 195 mm, the present invention in the form shown in FIGS. 3, 4A and 4B is used.

An experiment was performed for the case where a height protruding above the edge: 6 mm) was used and for the case where it was not used. When an equal amount of water was put into a pan having an outer diameter of 180 mm and having the form shown in FIG. 6, the lid was closed, and experiments were performed with and without the use of the heat radiation preventer 11 of the present invention. The temperature of the portion corresponding to the periphery of the pan at a height position of from 100 mm was 80 ° C. when the heat radiation preventer 11 of the present invention was not used, but rose to 100 ° C. when it was used. At this time, the experiment was performed with the heat of the gas burner maximized. As a result, the temperature of the portion corresponding to the periphery of the pan at a height of 100 mm from the upper surface of the gas range was 106 ° C. without using the heat radiation preventer 11 of the present invention. However, when used, the temperature rose to 151 ° C.
[0026]
Further, it was confirmed that the thermal power was improved by about 20% to 40% when the heat radiation preventing device 11 of the present invention was used, as compared with the case where the heat radiation preventing device 11 was not used.
[0027]
【The invention's effect】
