本考案は、囲炉裏の灰受箱底部中央に形成する火皿の上部焚部へ風速を調整して、焚部の薪や炭等の燃焼物の火力を調整することにより、各種料理に応じて適切な火力が得られるようにした火力調整可能な囲炉裏に関するものである。  The present invention is suitable for various dishes by adjusting the wind speed to the upper saddle of the fire tray formed in the center of the bottom of the ash receiving box in the hearth, and adjusting the thermal power of the burning material such as firewood and charcoal in the saddle This relates to a hearth that can be adjusted with a thermal power so that a good thermal power can be obtained.

例えば、特許文献１には、囲炉裏の炉室部に開口された通気孔に連通接続され外部から炉室部に空気を供給する通気路とを備え、該通気路には前記空気の流量を調整する空気量調整手段が設けられた囲炉裏装置の構造が記載されている。  For example, Patent Document 1 includes a vent passage that is connected to a vent hole that is opened in the furnace chamber portion of the hearth and supplies air to the furnace chamber portion from the outside, and the flow rate of the air is adjusted in the vent passage. The structure of the hearth device provided with the air amount adjusting means is described.

そして、この特許文献１には、「前記空気量調整手段５は、空気の流量を零、即ち通気路１７を遮断するとができるようになっていて、図２乃至図６に示すように、通気路１７内に配置されるダンパー翼５０が支軸５１を介して回動自在に軸支されてできている。このダンパー翼５０の回動を外部操作する操作ツマミ５３が前記炉縁１５に設けられていて、前記支軸５１および操作ツマミ５３を軸支する支軸５４の先端部はギアーボックス５６内でベベルギアー５７，５８を介して連結されている」〔００１０〕旨説明されている。  This Patent Document 1 states that “the air amount adjusting means 5 is capable of zeroing the air flow rate, that is, blocking the air passage 17, and as shown in FIGS. A damper blade 50 disposed in the passage 17 is pivotally supported via a support shaft 51. An operation knob 53 for externally operating the rotation of the damper blade 50 is provided on the furnace edge 15. Further, the tip end portion of the support shaft 51 that supports the support shaft 51 and the operation knob 53 is connected in the gear box 56 via bevel gears 57 and 58 ”[0010].

また、この特許文献１には、「炉室部に空気を供給する通気路が設けられ、該通気路に空気の流量を調整する空気量調整手段が設けられているため空気量調整手段を空気が流通し得るように操作することにより、炉室部内に外部から空気が供給され、常に炉室部に十分な量の酸素が供給されるので、酸素不足により引き起こされる不完全燃焼を防ぐことができる」〔００２１〕旨説明されている。  Further, in Patent Document 1, “the air passage for supplying air to the furnace chamber portion is provided, and the air amount adjusting means for adjusting the air flow rate is provided in the air passage. By operating so that air can circulate, air is supplied from the outside into the furnace chamber, and a sufficient amount of oxygen is always supplied to the furnace chamber, thereby preventing incomplete combustion caused by lack of oxygen. [0021] "is explained.

しかしながら、この特許文献１においては、囲炉裏の炉室部に十分な量の酸素が供給されなく酸素不足を引き起こすことにより生ずる不完全燃焼を防ぐようにしたものであり、炉室部には自然な空気を取り入れるようにしたものであって、囲炉裏底部の火皿上部焚部へ強制的にファンにより風を送り、その風速を調整することにより焚部の薪や炭等の燃焼物の火力を調整し、各料理に応じて適切な火力得られるようにしたものではない。  However, in Patent Document 1, a sufficient amount of oxygen is not supplied to the furnace chamber portion of the hearth and incomplete combustion caused by causing oxygen shortage is prevented. It is designed to take in air, and forcibly sends a wind to the top of the fireplate at the bottom of the hearth by a fan, and adjusts the wind speed to adjust the thermal power of firewood and fired combustibles. The proper firepower is not obtained for each dish.

また、特許文献２には、囲炉裏火箱に収納する耐火構造体に、空気流通坑を配置し、空気流通坑の配置には、耐火構造体側壁に空気流通坑口と空気坑を設け、底壁に設けられた空気坑を連結することで、灰が収納されて埋もれている側壁と底壁の空気坑を通して空気が自然に流通することを特徴とする囲炉裏が記載されている。  Further, in Patent Document 2, an air circulation mine is arranged in a refractory structure housed in a hearth firebox, and an air circulation mine is provided with an air circulation wellhead and an air mine on the side wall of the refractory structure. The hearth is characterized in that air is naturally circulated through the side wall and the bottom wall air mine where ash is stored and buried by connecting the air pits provided in the mine.

そして、特許文献２には、「空気流通坑口と空気坑を配置したことで、耐火構造体に収納する灰に側面から、又底面より灰全体に、空気が流通して酸素を含み燃焼する炭の底部全体に活力を与え燃焼が増強するので、灰の発生を抑制し、発生する二酸化炭素等の有害ガスをも抑制する従来とは全く異なる機能を有する新しい囲炉裏を提供する」〔００２２〕旨説明されている。  Patent Document 2 states that “the arrangement of the air circulation wellhead and the air well allows the air to flow from the side surface to the ash stored in the refractory structure and from the bottom surface to the entire ash to contain oxygen and burn. `` Provides a new hearth with a completely different function from the conventional one that suppresses the generation of ash and also suppresses harmful gases such as carbon dioxide, because it gives vitality to the whole bottom and enhances combustion. '' Explained.

しかしながら、この特許文献２においては、耐火構造体に収納する灰に側面から、又底面より灰全体に自然な空気を流通させて酸素を含み燃焼する炭火の底部全体に活力を与え燃焼が増強させるものであって、囲炉裏底部の火皿上部焚部へ強制的にファンにより風を送り、その風速を調整することにより焚部の薪や炭等の燃焼物の火力を調整し、各料理に応じて適切な火力を選択できるようにしたものではない。  However, in Patent Document 2, natural air is circulated from the side surface to the ash housed in the fireproof structure and from the bottom surface to the entire ash to give vitality to the entire bottom portion of the charcoal fire containing oxygen to enhance combustion. It is a thing, forcibly sends a wind to the upper part of the top of the pan of the hearth by a fan, adjusts the wind speed, adjusts the thermal power of the firewood and charcoal, etc. It is not intended to select the appropriate firepower.

また、特許文献３には、通風パイプ４ｂの両端が切断開口状で、図４に示すように、炉ケース４のケース壁を貫通して設けられ、その長さ中央付近に上方に突出する開口端４ｃが設けられ、この開口端４ｃ上に例えば円形状のネット４ｄを置き、その上で薪や炭が燃やされるようにした囲炉裏の構造が記載されている。  Further, in Patent Document 3, both ends of the ventilation pipe 4b are cut openings, and as shown in FIG. 4, the openings are provided penetrating through the case wall of the furnace case 4, and projecting upward near the center of the length thereof. An end 4c is provided, for example, a circular net 4d is placed on the open end 4c, on which a soot and charcoal structure is burned.

そして、特許文献３には、「薪や炭を燃やす際に、この囲炉裏では炉ケース４内に通風パイプ４ｂが設けられているため、ネット４ｄ上で燃料に対して空気が適当量自然に供給され、従って燃焼効率がよく、薪や炭を完全に燃やすことができ、不完全燃焼による有害成分の発生が防止される」〔００１６〕旨説明されている。  Patent Document 3 states that, “When burning firewood or charcoal, a ventilation pipe 4b is provided in the furnace case 4 in the hearth, so that an appropriate amount of air is naturally supplied to the fuel on the net 4d. Therefore, combustion efficiency is good, soot and charcoal can be burned completely, and generation of harmful components due to incomplete combustion is prevented ”[0016].

しかしながら、特許文献３においては、薪や炭を燃やす際に、囲炉裏の炉ケース内に通風パイプを設け、ネット４ｄ上の燃料に対して空気が適当量自然に供給されて、燃焼効率がよく薪や炭を完全に燃やすことができ、不完全燃焼による有害成分の発生が防止するものであって、囲炉裏底部の火皿上部焚部へ強制的にファンにより風を送り、その風速を調整することにより焚部の薪や炭等の燃焼物の火力を調整し、各料理に応じて適切な火力が得られるようにしたものでない。  However, in Patent Document 3, when burning soot or charcoal, a ventilation pipe is provided in the furnace case at the hearth of the hearth, and an appropriate amount of air is naturally supplied to the fuel on the net 4d so that the combustion efficiency is good. Can prevent the generation of harmful components due to incomplete combustion, forcibly send the wind by the fan to the upper part of the top of the pan of the hearth, and adjust the wind speed. It is not what adjusted the thermal power of burning things, such as firewood and charcoal of a buttock, and was able to obtain appropriate thermal power according to each dish.

課題を解決する手段Means to solve the problem

請求項１の考案は、囲炉裏の灰受箱底部中央に火皿を設置し、火皿の通気孔下方から火皿上部の焚部へ空気を供給するファンを設け、該ファンによる焚部への空気の風速を調整する風速調整手段を設けた火力調整可能な囲炉裏を提供するものである。  According to the first aspect of the present invention, a fire plate is installed in the center of the bottom of the ash receiving box at the hearth, and a fan is provided for supplying air from below the vent of the fire plate to the ridge of the upper portion of the platter. It is an object of the present invention to provide a hearth that can be adjusted in terms of thermal power, provided with a wind speed adjusting means for adjusting the temperature.

この考案においては、上記ファンによる火皿上部焚部への風速を調整することにより、焚部の薪や炭等の燃焼物の火力の強弱を調整することができ、各料理に応じて適切な火力の強弱を選択することができる。  In this device, by adjusting the wind speed to the upper plateau of the pan by the fan, it is possible to adjust the strength of the firepower of the firewood and charcoal, etc. Can be selected.

また、請求項２の考案は、前記風速調整手段における風速が０〜３ｍ／ｓｅｃの範囲で調節するようにした請求項１記載の火力調整可能な囲炉裏を提供するものである。  The invention of claim 2 provides the hearth with adjustable thermal power according to claim 1, wherein the wind speed in the wind speed adjusting means is adjusted within a range of 0 to 3 m / sec.

この考案においては、前記風速調整手段における風速を０〜３ｍ／ｓｅｃの範囲において、例えば、送風停止＝０ｍ／ｓｅｃ（蒸らし）、弱火＝０．２〜０．６ｍ／ｓｅｃ、中火＝０．７〜１．５ｍ／ｓｅｃ、強火＝１．６〜３ｍ／ｓｅｃの様に選択して、各種料理に応じて適切な火加減を得る火力調整可能な囲炉裏を提供することができる。  In the present invention, the wind speed in the wind speed adjusting means is in the range of 0 to 3 m / sec, for example, air blow stop = 0 m / sec (steaming), low fire = 0.2 to 0.6 m / sec, medium fire = 0. By selecting 7 to 1.5 m / sec and strong fire = 1.6 to 3 m / sec, it is possible to provide a hearth that can be adjusted in terms of heating power to obtain appropriate heating depending on various dishes.

また、請求項３の考案は、前記火皿の上方に上置プレートの搭載枠を設け、火皿と上置プレート底面との間隔が５〜３０ｃｍで、該搭載枠上に設置する上置プレートの外周が焚部の外周より２〜１０ｃｍ大きくした請求項１〜２の何れかに記載の火力調整可能な囲炉裏を提供するものである。  According to a third aspect of the present invention, an upper plate mounting frame is provided above the pan, and the interval between the pan and the upper plate bottom surface is 5 to 30 cm, and the outer periphery of the upper plate installed on the mounting frame. It provides the hearth with adjustable heating power according to any one of claims 1 to 2, wherein the inner wall is larger by 2 to 10 cm than the outer periphery of the flange.

この考案においては、搭載枠上に別途金網を設置して金網上で直接焼肉・焼き魚等を調理することができることは勿論、搭載枠上に上置プレートを設置して上置プレート上面で直接鉄板料理又は上置プレート上面に鍋や釜等をのせて多種の料理（焼肉料理、焼魚料理、フライパン料理、すき焼、鍋料理、ご飯炊き等）が行うことができる。この際、鍋や釜等の外側面には上置プレートに搭載するので薪等の燃焼時の炭が付着しにくい。  In this device, you can install a separate metal mesh on the mounting frame and cook grilled meat and grilled fish directly on the metal mesh. Of course, you can install an upper plate on the mounting frame and directly touch the iron plate on the upper surface of the upper plate. Various dishes (grilled meat dishes, grilled fish dishes, frying pan dishes, sukiyaki dishes, hot pot dishes, rice cooked dishes, etc.) can be performed by placing a pot or kettle on the upper surface of the dish or the upper plate. In this case, charcoal such as soot is not easily attached to the outer surface of the pan, the pot or the like because it is mounted on the upper plate.

火皿と搭載枠上の金網又は上置プレート底面との間隔は５〜３０ｃｍが好ましい。５ｃｍ未満では火皿と搭載枠上の金網又は上置プレート底面との間隔が狭過ぎ、小さな炭は投入できても、薪等は大きいため投入が困難となる。また、３０ｃｍを超えると火皿と搭載枠上の金網又は上置プレート底面との間隔が遠過ぎ、炭や薪等の燃焼物の火力が効率よく得られない。  The distance between the pan and the wire mesh on the mounting frame or the bottom surface of the upper plate is preferably 5 to 30 cm. If it is less than 5 cm, the interval between the fire tray and the wire mesh on the mounting frame or the bottom surface of the mounting plate is too narrow. Moreover, if it exceeds 30 cm, the space | interval of a fire pan and the wire mesh on a mounting frame, or an upper plate bottom face is too far, and the thermal power of combustion substances, such as charcoal and firewood, cannot be obtained efficiently.

さらに、上置プレートの外周が焚部の外周より２〜１０ｃｍ大きくすることが必要である。２ｃｍ未満であると火皿上部焚部で燃焼する薪や炭等の火の粉が食卓周辺に散るのを確実に防止できない。また、１０ｃｍを超えると炭や薪等を火皿上の焚部に対し上置プレート周囲が大きくなり過ぎ薪や炭等の燃焼物の投入がやりつらくなる。好ましくは、３〜５ｃｍである。尚、焚部の外周は投入物の大きさにより変化し、通常５〜２５ｃｍ程度である。  Furthermore, it is necessary to make the outer periphery of the upper plate 2-10 cm larger than the outer periphery of the collar. If it is less than 2 cm, fire dust such as firewood and charcoal that burns at the top of the pan can not be reliably prevented from spreading around the table. Moreover, when it exceeds 10 cm, charcoal, firewood, etc. will become too large around an upper plate with respect to the collar part on a fire pan, and it will become difficult to throw in combustibles, such as firewood, charcoal. Preferably, it is 3-5 cm. In addition, the outer periphery of a collar part changes with the magnitude | sizes of input material, and is about 5-25 cm normally.

また、請求項４の考案は、前記火皿の面積が２５〜９００ｃｍ２の範囲で、火皿の通気孔の空孔率が２０〜９０％にある請求項１〜３の何れかに記載の火力調整可能な囲炉裏を提供するものである。Further, the invention of claim 4, the range area of 25～900Cm 2 of chafing dish, thermal adjustment according to claim 1, porosity of the vent hole of the pipe bowl is in the 20% to 90% It provides a possible hearth.

この考案においては、前記火皿の面積が２５〜９００ｃｍ２の範囲であることが適切である。火皿の面積が２５ｃｍ２未満であると火皿上部の焚部の面積が狭過ぎ、薪や炭等の燃焼範囲が狭く充分な火力を得ることができない。一方、火皿の面積が９００ｃｍ２を超えると火皿上部の焚部の面積が広く薪や炭等の燃焼範囲が広がるため薪や炭等の燃焼物が無駄に消費される。好ましくは、６０〜４００ｃｍ２である。In this device, it is appropriate that the area of the pan is in the range of 25 to 900 cm 2 . If the area of the pan is less than 25 cm 2 , the area of the heel portion at the top of the pan is too narrow, and the burning range of firewood, charcoal, etc. is narrow and sufficient fire power cannot be obtained. On the other hand, if the area of the baking pan exceeds 900 cm 2 , the area of the heel portion at the top of the baking pan is wide and the combustion range of firewood, charcoal, etc. is widened, so that the combustion products such as firewood, charcoal, etc. are wasted. Preferably, a 60~400cm 2.

火皿の通気孔の空孔率が２０〜９０％であることが重要である。空孔率が２０％未満であると火皿上部の焚部に均一な風を送ることができず、空孔率が９０％を超えると灰受箱の灰や火皿上部の未燃焼物が灰排出穴に貯まる。好ましくは、３０〜６０％である。  It is important that the porosity of the vent in the pan is 20-90%. If the porosity is less than 20%, uniform air cannot be sent to the buttocks at the top of the pan, and if the porosity exceeds 90%, the ash in the ash tray and the unburned material at the top of the pan are discharged ashes. Accumulate in the hole. Preferably, it is 30 to 60%.

また、請求項５の考案は、前記上置プレート外周に火の粉飛散防止スカートを設けた請求項１〜４の何れかに記載の火力調整可能な囲炉裏を提供するものである。  The invention of claim 5 provides the hearth with adjustable fire power according to any one of claims 1 to 4, wherein a skirt for preventing spark scattering is provided on the outer periphery of the upper plate.

この考案においては、火皿上部焚部で燃焼する薪や炭等の火の粉が食卓周辺に飛散るのを確実に防止できる。または、上置プレートの外周を小さくしても薪や炭等の火の粉が食卓周辺に飛散るのを防止できる。  In this device, it is possible to surely prevent fire powder such as firewood and charcoal that burns in the upper bowl of the pan from being scattered around the table. Or, even if the outer periphery of the upper plate is made smaller, it is possible to prevent sparks such as firewood and charcoal from scattering around the table.

また、請求項６の考案は、前記火皿の下方に囲炉裏側面にかけて灰排出穴を設け、灰排出穴の囲炉裏側面開口に前記ファンを開閉自在に形成した請求項１〜５の何れかに記載の火力調整可能な囲炉裏を提供するものである。  Further, the invention of claim 6 is the invention according to any one of claims 1 to 5, wherein an ash discharge hole is provided on the side of the hearth bottom below the fire pan, and the fan is formed to be openable and closable at the hearth side opening of the ash discharge hole.

以下に本考案の一実施形態を図面に基づき説明する。
図１は本考案の一実施例を示す平面図、図２は図１のＩＩ−ＩＩ線概略断面図、図３は焚部の要部拡大断面図である。Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing an embodiment of the present invention, FIG. 2 is a schematic cross-sectional view taken along the line II-II of FIG. 1, and FIG.

図１〜３に示す如く、囲炉裏Ｉの灰受箱１底部中央に火皿２を設置し、火皿２の通気孔３・・・下方から火皿２上部の焚部Ａへ空気を供給するファン４を囲炉裏１の側面に設け、該ファン４による焚部Ａへの空気の風速を調整する風速調整手段Ｓ（ダイヤル式ツマミ）を設けている。尚、Ｔはテーブル、Ｂは断熱材、Ｃは灰である。  As shown in FIGS. 1 to 3, a fire plate 2 is installed in the center of the bottom of the ash receiving box 1 of the hearth I, and a fan 4 that supplies air from the bottom of the vent 3 of the fire plate 2 to the flange A of the top of the pan 2. Wind speed adjusting means S (dial type knob) is provided on the side surface of the hearth 1 to adjust the wind speed of the air toward the flange A by the fan 4. T is a table, B is a heat insulating material, and C is ash.

前記風速調整手段Ｓにおける風速は０．２〜３ｍ／ｓｅｃの範囲で例えば、図２に示すように、送風停止＝０ｍ／ｓｅｃ（蒸らし）、弱火＝０．２〜０．６ｍ／ｓｅｃ、中火＝０．７〜１．５ｍ／ｓｅｃ、強火＝１．６〜３ｍ／ｓｅｃの様に選択して、各種料理に応じて適切な火加減を得るようにしている。前記風速調整手段Ｓにおける風速は０．２〜３ｍ／ｓｅｃの範囲で、自由に選択してもよく、送風停止、弱火、中火、強火とそれぞれ設定した風速を選択するようにしてもよい。  The wind speed in the wind speed adjusting means S is in the range of 0.2 to 3 m / sec. For example, as shown in FIG. 2, the air blowing stop = 0 m / sec (steaming), the low heat = 0.2 to 0.6 m / sec, Selection is made such that fire = 0.7 to 1.5 m / sec, high fire = 1.6 to 3 m / sec, and an appropriate fire control is obtained according to various dishes. The wind speed in the wind speed adjusting means S may be freely selected in the range of 0.2 to 3 m / sec, and the wind speeds set as blast stop, low fire, medium fire, and high fire may be selected.

図３に示すように、前記火皿２の上方に上置プレート５を設け、この搭載枠６を火皿２と上置プレート５底面との間隔Ｈが１３ｃｍとなるようにし、該搭載枠６上に設置する上置プレート５の外周が焚部Ａの外周より３ｃｍ（幅Ｄ）大きくしている。尚、上記上置プレート５は、直径が約４０ｃｍであり、赤外線効果を有する材料を使用することが好ましい。６ａは灰受箱１内側縁に上置プレート５を固定する固定枠である。  As shown in FIG. 3, an upper plate 5 is provided above the pan 2, and the mounting frame 6 is set so that the distance H between the pan 2 and the bottom of the upper plate 5 is 13 cm. The outer circumference of the upper plate 5 to be installed is 3 cm (width D) larger than the outer circumference of the flange A. The upper plate 5 is preferably made of a material having a diameter of about 40 cm and having an infrared effect. 6a is a fixed frame for fixing the upper plate 5 to the inner edge of the ash receiving box 1;

前記火皿２の面積は１００ｃｍ２の範囲で、火皿２の通気孔３・・・の空孔率を約５０％としている。The area of the pan 2 is 100 cm 2 , and the porosity of the vent holes 3... Of the pan 2 is about 50%.

また、図２及び図３に示すように、前記上置プレート５外周に火の粉飛散防止スカート７を設けると火の粉の食卓への飛散の防止がより確実に行える。  Further, as shown in FIGS. 2 and 3, if a spark scatter prevention skirt 7 is provided on the outer periphery of the upper plate 5, it is possible to more reliably prevent the spark from being scattered on the table.

前記火皿２の下方に囲炉裏側面８にかけて灰排出穴９を設け、前記ファン４を灰排出穴９の囲炉裏側面開口１０に開閉自在に形成している。このような構造においてはファン４からの風量が増大すると灰排出穴９で風圧状態となる。したがって、火皿の面積を小さくかつ通気孔の空孔率を小さくして、焚部への風速が増大させることにより燃焼効率を向上させるようにすることができる。一方、火皿の面積を大きくかつ通気孔の空孔率を大きくして、焚部への風速を弱くすることができる。尚、囲炉裏側面開口１０に蓋１２を開閉自在に形成して焚部へ空気の進入を完全に阻止することができる。  An ash discharge hole 9 is provided on the bottom side 8 of the hearth 2 below the pan 2, and the fan 4 is formed in the open side 10 of the ash discharge hole 9 so as to be freely opened and closed. In such a structure, when the air volume from the fan 4 increases, the ash discharge hole 9 enters a wind pressure state. Therefore, it is possible to improve the combustion efficiency by reducing the area of the pan and reducing the porosity of the vent hole and increasing the wind speed to the flange. On the other hand, it is possible to increase the area of the pan and increase the porosity of the ventilation holes, thereby reducing the wind speed to the heel. In addition, the lid 12 can be formed to be openable and closable at the hearth side opening 10 to completely prevent air from entering the heel.

Can be selected.

また、前記風速調整手段における風速を０〜３ｍ／ｓｅｃの範囲において、各種料理に応じて適切な火加減を得ることができる。  Moreover, in the range of 0-3 m / sec of the wind speed in the said wind speed adjustment means, suitable heating can be obtained according to various dishes.

また、搭載枠上に金網を設置して網上で直接焼肉・焼き魚等を調理することができる一方、搭載枠上に上置プレートを設置して上置プレート上面で直接鉄板料理又は上置プレート上面に別個の鍋や釜等をのせて多種の料理（焼肉料理、焼魚料理、フライパン料理、すき焼、鍋料理、ご飯炊き等）をすることができる。尚、上記上置プレート５に遠赤外線効果を有する材料を使用すると調理する食材の火の通りを良好にして美味しく仕上がる。この際鍋や釜等の外周には薪等の燃焼炭が直接付着しない。上置プレートは燃焼物の炎の荒熱を吸収して鍋等に均一な徹を伝える。  In addition, while installing a wire mesh on the mounting frame, you can cook grilled meat and grilled fish directly on the net, while installing an upper plate on the mounting frame and directly cooking on the top plate or iron plate Various dishes (grilled meat dishes, grilled fish dishes, frying pan dishes, sukiyaki dishes, hot pot dishes, cooked rice, etc.) can be prepared by placing a separate pot or kettle on the top surface. In addition, when the material which has a far-infrared effect is used for the said upper plate 5, it will be finished deliciously by making the street of the food to cook well. At this time, combustion charcoal such as firewood does not directly adhere to the outer periphery of the pan or the pot. The upper plate absorbs the rough heat of the flame of the combustion product and conveys the uniform to the pan.

また、上置プレートの外周を火皿の外周より大きくすることにより。火皿上部焚部で燃焼する薪や炭等の火の粉が食卓周辺に飛散するのを防止することができる。また、火の粉飛散防止スカートを設けると、上置プレートの外周を火皿の外周より極端に大きくしなくても、火皿上部焚部で燃焼する薪や炭等の火の粉が食卓周辺に散るのを確実に防止できる。粉飛散防止スカートはさらに食卓に座る人に対する熱気を防ぐこともできる。  Also, by making the outer periphery of the upper plate larger than the outer periphery of the pan. It is possible to prevent fire powder such as firewood and charcoal that burns in the upper bowl of the pan from being scattered around the table. In addition, if a skirt for preventing sparks is provided, it is ensured that fire powder such as firewood or charcoal that burns in the upper buttock of the upper plate is scattered around the table without making the outer periphery of the upper plate extremely larger than the outer periphery of the pan. Can be prevented. The powder scattering skirt can also prevent hot air for people sitting at the table.

また、火皿の面積及び空孔率を一定にして薪や炭等の燃焼範囲を適正にすることにより効率的に火力を得ることができると共に、燃焼物の消費を無駄にしない。  In addition, by making the area of the pan and the porosity constant and optimizing the combustion range of firewood, charcoal, etc., it is possible to efficiently obtain thermal power and not to waste consumption of combustibles.

さらに、前記ファンにより選択した一定の風速を確保して一定の面積を有し一定の空孔率を有する火皿の通気孔より、焚部の薪や炭等の燃焼物に適量の空気（酸素）を送ることができ、各種料理に応じて適切な燃焼物の火力を得ることができる。  Further, an appropriate amount of air (oxygen) is supplied to the burned material such as firewood and charcoal from the fire tray through the vent hole of the fire tray having a constant area and a constant porosity while ensuring a constant wind speed selected by the fan. It is possible to send a firepower of an appropriate combustion product according to various dishes.
