【5】 在利用如專利文獻1之加熱調理器進行調理之情形，一般而言，首先，為了使鍋內之液體沸騰而以強火進行加熱。然後，在鍋內之液體沸騰後，為了防止鍋內之液體早期蒸發、或鍋底燒焦等情況，而將火力調降至中火。【6】 於專利文獻2記載之燃燒器中，在將火力從強火調降至中火的情形，存在有如下之傾向：從燃燒器之內周壁火焰孔噴出之火焰並未如此程度變小，而另一方面，從燃燒器之外周壁火焰孔噴出之火焰變小。因此，存在有如下之傾向：在載置於燃燒器上部之加熱對象物之中央部溫度未如此程度下降，而另一方面，在加熱對象物之外周部溫度變低。【7】 因此，在使用以專利文獻2之燃燒器作為專利文獻1之加熱調理器之加熱源的情形，恐存在有如下之情況：即使將火力從強火調降至中火，亦由於構成加熱對象物之中央部的鍋之溫度未如此程度下降，因此使鍋內之液體持續沸騰且鍋內之液體早期蒸發、或鍋底燒焦等。另一方面，恐存在有如下之情況：由於構成加熱對象物之外周部的燒成板之溫度下降，因此使燒成板上之燒肉難以燒烤。【8】 如此般，在習知的加熱源中，並未被想到如下所述般之在加熱對象物之中央部與外周部改變加熱之強弱，亦即，例如在加熱對象物之中央部使加熱變弱，另一方面，在加熱對象物之外周部維持加熱狀態。【9】 本發明係有鑑於上述新穎之課題而完成者，目的在於提供一種可改變加熱對象物之中央部與外周部之加熱強弱的加熱調理器。尤其是，目的在於提供一種在調降火力之情形，可使中央部之鍋的加熱變弱，另一方面，維持外周部之網體的加熱之加熱調理器。【10】 本發明之第一特徵，係具備燃燒器、及送風手段；該燃燒器，具備：上方開口狀之箱體；調理部，係載置於箱體，且將中央設為鍋載置部、將鍋載置部之周圍設為網體而構成；熱板，係配置於調理部之下方，且具有中央開口部；雙層圓筒部，係配置於熱板之下方，且以內筒部及外筒部構成；以及供給管，係與形成於圓筒部與外筒部之間之空間連通，且具有主空氣之流入口；於內筒部及外筒部，將供給於供給管之燃料氣體與主空氣之混合氣體噴出之內周火焰孔及外周火焰孔以朝向斜上方之狀態分別設置複數個，且內筒部內側形成有次空氣之流路，而藉由送風手段供給主空氣及次空氣。【11】 藉由從送風手段強制性地將主空氣與燃料氣體一起供給於供給管，使得燃燒速度之一方相較於混合氣體之噴出速度更快，因此從內周火焰孔噴出之火焰產生返回燃燒器內部之現象。其結果為，從內周火焰孔噴出之火焰之火力範圍變小。而且，藉由從內周火焰孔噴出之火焰之火力範圍變小，減少與從其他內周火焰孔噴出之火焰之碰撞而不會有火焰之火力範圍變大之情況，且不直接使火焰接觸鍋載置部。進一步地，藉由供給於圓筒部內側之次空氣之上升，熱氣流從熱板內與熱板之中央開口部往上部之鍋載置部進行分流，因此使熱分散。其結果為，可藉由使鍋載置部之加熱變弱而使鍋載置部之溫度降低。藉此，可抑制載置於鍋載置部之鍋之過熱、抑制鍋內液體之過度沸騰。【12】 此外，藉由從送風手段強制性地將次空氣供給於燃燒器之圓筒部內側，使得從內周火焰孔噴出之火焰藉由熱板分流，傳遞於熱板之下面而往熱板之外周流動。而且，由從內周火焰孔噴出之火焰加熱過之熱氣流，傳遞於熱板之下面而從熱板之外周緣部往上方噴出，對網體進行加熱。其結果為，設置於中央部之鍋載置部的加熱變弱而溫度下降，另一方面，維持設置於鍋載置部之周圍之網體的加熱。【13】 本發明之第二特徵，係進一步具備至少圍繞該外筒部之壁部，且外筒部與壁部之間隙形成有次空氣之流路。【14】 藉由強制性地將次空氣供給於燃燒器之外筒部與壁部之間隙，利用該上升之次空氣之吸引誘導而將熱板內之周圍之熱氣流導往熱板之外周緣部，並且從外周火焰孔噴出之火焰亦往熱板之外周流動。而且，由從外周火焰孔噴出之火焰加熱過之熱氣流，從熱板之外周緣部往上方噴出，對網體進行加熱。進一步地主要藉由主空氣之供給使燃燒狀態良好地進行，因此發熱量增加之狀態之熱氣流以於熱板內分流之狀態導往熱板之外周緣部。其結果為，可維持網體之加熱、防止網體之溫度下降。【15】 本發明之第三特徵，係於箱體內設置有較熱板更為大徑且圍繞外周火焰孔之環狀之引導壁。【16】 較熱板為大徑且圍繞外周火焰孔之環狀之引導壁，發揮將由從外周火焰孔噴出之火焰加熱過之熱氣流導往上方的功能。也就是，流往熱板之外周的熱氣流，藉由引導壁而改變方向往上方，且藉由從熱板之外周緣部與引導壁之間噴出而加熱網體。其結果為，可維持網體之加熱、防止網體之溫度下降。進一步地，藉由設置有引導壁，抑制從外周火焰孔噴出之火焰直接接觸箱體而使箱體過熱，藉此可防止從網體往箱體內壁滴下之肉汁等造成之污垢之燒焦。【17】 本發明之第四特徵，係進一步具備有用以調節送風手段之風量的風量調節手段。【18】 藉由具備有用以調節來自送風手段之風量的風量調節手段，可調節從內周火焰孔及外周火焰孔噴出之火力範圍之大小、或熱氣流之速度。其結果為，可調節鍋載置部及網體之加熱。【19】 本發明之第五特徵，係進一步具備平台、及收容箱體之第二箱體，且第一箱體及第二箱體配置於平台之下方，而於第一箱體與第二箱體之間形成吸引空間，於吸引空間設置排放氣體吸引口，並且於第二箱體形成有與排氣流路連通之排氣口。【20】 藉由設成為上述構成，可提供一種能夠吸引在調理時從鍋產生之湯氣、或於網體上燒烤食物時所產生之煙的無煙加熱調理器。【21】 根據本發明，可提供一種能夠改變加熱對象物之中央部與外周部之加熱之強弱的加熱調理器。尤其是，可提供一種能夠抑制中央之鍋載置部之過熱並防止鍋內之液體之過度沸騰，另一方面，維持鍋載置部周圍之網體之加熱且防止網體之溫度下降的加熱調理器。[5] In the case of conditioning using the heating conditioner of Patent Document 1, generally, first, in order to boil the liquid in the pot, heating is performed by a strong fire. Then, after the liquid in the pot boils, in order to prevent the early evaporation of the liquid in the pot or the burning of the bottom of the pot, the firepower is reduced to medium fire. [6] In the burner described in Patent Document 2, in the case where the fire power is reduced from a strong fire to a medium fire, there is a tendency that the flame ejected from the flame hole in the inner peripheral wall of the burner is not so small. On the other hand, the flame ejected from the flame hole in the outer wall of the burner becomes small. Therefore, there is a tendency that the temperature in the central portion of the object to be heated placed on the upper portion of the burner does not decrease to such a degree, and on the other hand, the temperature in the peripheral portion of the object to be heated becomes lower. [7] Therefore, in the case where the burner of Patent Document 2 is used as the heating source of the heating conditioner of Patent Document 1, there is a case where even if the fire power is lowered from the strong fire to the medium fire, the heating is constituted. The temperature of the pot in the central portion of the object is not lowered to such an extent that the liquid in the pot is continuously boiled and the liquid in the pot is evaporated early, or the bottom of the pot is scorched. On the other hand, there is a case where the temperature of the fired sheet constituting the outer peripheral portion of the object to be heated is lowered, so that it is difficult to grill the burnt meat on the fired board. [8] In the conventional heating source, it is not thought that the heating strength is changed in the central portion and the outer peripheral portion of the object to be heated as described below, that is, for example, in the central portion of the object to be heated The heating is weakened, and on the other hand, the heating state is maintained in the outer periphery of the object to be heated. [9] The present invention has been made in view of the above-described novel problems, and an object of the invention is to provide a heating conditioner capable of changing the heating strength of a central portion and an outer peripheral portion of a heating target. In particular, it is an object of the invention to provide a heating conditioner which can heat the pot of the center portion while reducing the heating power, and maintain the heating of the net body at the outer peripheral portion. [10] The first feature of the present invention includes a burner and a blowing means; the burner includes: a casing having an open upper shape; and a conditioning unit placed on the casing and having the center placed in a pot a portion of the pot placing portion is a net body; the hot plate is disposed below the conditioning portion and has a central opening; the double-layered cylindrical portion is disposed below the hot plate and is disposed inside the inner tube And the supply pipe is connected to a space formed between the cylindrical portion and the outer tubular portion, and has an inlet for the main air; and the inner tubular portion and the outer tubular portion are supplied to the supply pipe The inner peripheral flame hole and the outer peripheral flame hole of the mixture of the fuel gas and the main air are respectively disposed in a state of being inclined upward, and a flow path of the secondary air is formed inside the inner cylinder portion, and the air is supplied to the main body by the air supply means. Air and secondary air. [11] By forcibly supplying main air and fuel gas to the supply pipe from the air supply means, one of the combustion speeds is faster than the discharge speed of the mixed gas, so that the flame ejected from the inner peripheral flame hole is returned. The phenomenon inside the burner. As a result, the range of the fire force of the flame ejected from the inner peripheral flame hole becomes small. Moreover, by reducing the range of the fire force of the flame ejected from the inner peripheral flame hole, the collision with the flame ejected from the other inner peripheral flame holes is reduced without the fire range of the flame becoming larger, and the flame is not directly contacted. Pot placement section. Further, by the rise of the secondary air supplied to the inside of the cylindrical portion, the hot air flow is branched from the central opening portion of the hot plate and the central opening portion of the hot plate to the upper pot placing portion, so that the heat is dispersed. As a result, the temperature of the pot placing portion can be lowered by weakening the heating of the pot placing portion. Thereby, it is possible to suppress overheating of the pan placed on the pot placing portion and to suppress excessive boiling of the liquid in the pan. [12] Further, by forcibly supplying the secondary air to the inside of the cylindrical portion of the burner from the air blowing means, the flame ejected from the inner peripheral flame hole is branched by the hot plate and transferred to the lower side of the hot plate to be heated. The board flows around the perimeter. Further, the hot air stream heated by the flame ejected from the inner peripheral flame hole is transmitted to the lower surface of the hot plate and ejected upward from the outer peripheral portion of the hot plate to heat the net body. As a result, the heating of the pot placing portion provided in the center portion is weakened and the temperature is lowered, and the heating of the net body provided around the pot placing portion is maintained. [13] According to a second aspect of the present invention, a wall portion surrounding at least the outer tubular portion is further provided, and a flow path of the secondary air is formed in a gap between the outer tubular portion and the wall portion. [14] By forcibly supplying the secondary air to the gap between the outer tube portion and the wall portion of the burner, the hot air flow in the hot plate is guided to the outer periphery of the hot plate by the suction induction of the rising air. The edge, and the flame ejected from the peripheral flame hole also flows to the outside of the hot plate. Further, the hot air stream heated by the flame ejected from the outer peripheral flame hole is ejected upward from the outer peripheral portion of the hot plate to heat the net body. Further, the combustion state is favorably performed mainly by the supply of the main air, so that the hot air flow in a state where the amount of heat generation is increased is guided to the outer peripheral portion of the hot plate in a state of being branched in the hot plate. As a result, the heating of the net body can be maintained and the temperature of the net body can be prevented from dropping. [15] A third feature of the present invention is that an annular guide wall having a larger diameter than the hot plate and surrounding the outer peripheral flame hole is provided in the casing. [16] The hot plate is a large diameter and surrounds the annular guide wall of the outer peripheral flame hole, and functions to guide the hot air flow heated by the flame ejected from the outer peripheral flame hole upward. That is, the hot air current flowing to the outer periphery of the hot plate is redirected upward by the guide wall, and the mesh body is heated by ejecting from between the outer peripheral portion of the hot plate and the guide wall. As a result, the heating of the net body can be maintained and the temperature of the net body can be prevented from dropping. Further, by providing the guide wall, it is possible to prevent the flame ejected from the outer peripheral flame hole from directly contacting the casing and superheating the casing, thereby preventing the scorching of the dirt caused by the gravy or the like dripping from the net body to the inner wall of the casing. [17] The fourth feature of the present invention is further provided with an air volume adjusting means for adjusting the air volume of the air blowing means. [18] By providing an air volume adjusting means for adjusting the amount of air from the air blowing means, the range of the fire force ejected from the inner peripheral flame hole and the outer peripheral flame hole or the speed of the hot air flow can be adjusted. As a result, the heating of the pot placing portion and the net body can be adjusted. [19] The fifth feature of the present invention further includes a platform and a second case for accommodating the box, wherein the first box and the second box are disposed below the platform, and the first box and the second box A suction space is formed between the tanks, an exhaust gas suction port is provided in the suction space, and an exhaust port communicating with the exhaust gas flow path is formed in the second tank. [20] By providing the above configuration, it is possible to provide a smokeless heating conditioner capable of attracting the soup gas generated from the pan during conditioning or the smoke generated when the food is grilled on the mesh body. According to the present invention, it is possible to provide a heating conditioner capable of changing the heating strength of the central portion and the outer peripheral portion of the object to be heated. In particular, it is possible to provide a heating capable of suppressing overheating of the central pot placing portion and preventing excessive boiling of the liquid in the pan, and on the other hand, maintaining the heating of the mesh body around the pot placing portion and preventing the temperature of the net body from dropping.

如同上述，在本實施形態中，燃燒器17構成為可分解燃燒器本體21與燃燒器頭22，因此燃燒器17之清理變容易。另外，燃燒器17，亦可為非構成為可分解燃燒器本體21與燃燒器頭22者，而使燃燒器本體21與燃燒器頭22構成為一體。此外，供給管20，並不限於從燃燒器本體外筒部21之外周面往下方延伸之構成，亦可為從燃燒器本體外筒部21往水平方向延伸之構成。【45】 如圖6(b)所示，燃燒器17之供給管20內部，於連通部20b與流入口20a之間具有窄縮部20c。具體而言，係構成為：從供給管20內部之連通部20b至窄縮部20c，內徑連續地縮徑；從窄縮部20c朝向流入口20a，內徑連續地擴徑。供給管20內部以上述之方式構成，藉此於供給管20內部供給燃料氣體時，藉由文土里效應(Venturieffect)將主空氣往供給管20內部吸引。【46】 如圖6(c)所示，形成於供給管20之底面的流入口20a，主要由用以導入燃料氣體之圓形狀開口的燃料氣體導入口20d、及形成於燃料氣體導入口20d之周圍之扇形狀開口的主空氣導入口20e構成。於燃料氣體導入口20d***氣體噴嘴24，從氣體噴嘴24將燃料氣體往供給管20內部供給。燃料氣體導入口20d，形成為較氣體噴嘴24之外徑更為大徑，因此，如圖1所示，於燃料氣體導入口20d與氣體噴嘴24之間形成間隙20f。因此，主空氣成為除了從主空氣導入口20e外，亦從間隙20f導入。【47】 圖8(a)係表示調節氣閘(damper)25之俯視圖，圖8(b)係表示圖8(a)中之調節氣閘25之D-D箭頭剖面圖。於供給管20之底面，安裝有用以調節從主空氣導入口20e導入之主空氣之供給量的調節氣閘25。調節氣閘25，構成為可繞供給管20之軸心旋轉。調節氣閘25，具有：由冠狀構件構成且與燃料氣體導入口20d大致同徑之圓形狀開口部25a、形成於圓形狀開口部25a之周圍的扇形狀開口部25b、以及形成於圓形狀開口部25a之周圍且不形成扇形狀開口部25b之區域即遮蔽區域25c。另外，圖8例示了形成有2個扇形狀開口25b之情形。調節氣閘25，以圓形狀開口部25a之軸心與燃料氣體導入口20d之軸心一致之方式安裝於供給管20之底面。而且，扇形狀開口25b，在已將調節氣閘25安裝於供給管20底面時，設置於在徑方向中與主空氣導入口20e對應之位置。【48】 主空氣之供給量，係藉由使調節氣閘25旋轉而調節主空氣導入口20e之開口度而進行。亦即，在主空氣導入口20e與扇形狀開口25b來到剛好重疊之位置時，主空氣導入口20e之開口度成為最大，主空氣之供給量亦成為最大。此外，在欲將主空氣之供給量變小之情形，使調節氣閘25旋轉而使遮蔽區域25c位於主空氣導入口20e上，也就是，以使遮蔽區域25c閉塞主空氣導入口20e，而使主空氣導入口20e之開口度變小之方式進行調節。若調節氣閘25之位置決定了，則例如藉由螺釘等之緊固手段將調節氣閘25固定於供給管20之底面。以如此方式，可對從主空氣導入口20e導入之主空氣之供給量進行調節。【49】 圖9(a)係表示殼體26之俯視圖，圖9(b)係表示殼體26之左側視圖。於內箱4之下方，配置有殼體26，於殼體26內設置有風扇27(送風手段之一例)。於殼體26外面之風扇27之風之取入口，設置有用以調節風量之風量調節手段28。本實施形態中之風量調節手段28，由設置有複數個長孔狀開口之板狀構件構成，而可藉由調節長孔狀開口之開口面積調節風量。另外，風量調節手段28，不限於上述般之將板狀構件安裝於風扇27之風之取入口的構成，亦可例如為改變風扇27之葉片之旋轉數般之電氣性的控制手段。此外，風扇27並不一定必需設於殼體26內，亦可例如於殼體26之外設置風扇27，以配管連接風扇27與殼體26而將風送往殼體26內。【50】 殼體26之上面，具有與內箱4之底部開口部4d連通之複數個開口26a。複數個開口26a之中的1個，係用以***燃燒器17之供給管20之開口26b，且形成為較供給管20之下端部之外徑更為大徑。【51】 圖10係表示承接皿29之俯視圖。於殼體26之上面，載置有承接皿29；承接皿29，具有與開口26b大致同徑之(亦即，較供給管20之下端部之外徑更為大徑之)供給管***口29a、圓弧狀開口29b、及供燃燒器17之突起部21h***之突起部***口29c。承接皿29，以供給管***口29a之軸心與開口26b之軸心一致之方式，載置於殼體26上面。而且，在將供給管20***於供給管***口29a時，燃燒器17之突起部21h嵌入於突起部***口29c，藉此將燃燒器17支持於承接皿29上。此時，於燃料氣體導入口20d，***設置於殼體26內之底部的氣體噴嘴24。【52】 開口26b係較供給管20之外徑更為大徑，因此於開口26b與供給管20之間形成間隙。因此，從風扇27送風之次空氣，於該間隙或開口26a上升。進一步地，供給管***口29a係較供給管20之外徑更為大徑，因此亦於供給管***口29a與供給管20之間形成有間隙。因此，次空氣通過該間隙或圓弧狀開口29b，然後，於雙層圓筒部18之內筒部18a內側、及外筒部18b與周壁4e之間隙上升。【53】 圖11，係表示有主空氣、燃料氣體、混合氣體、次空氣、火焰及熱氣流之流動的示意圖。一邊參照圖11，一邊對主空氣、燃料氣體、混合氣體、次空氣、火焰及熱氣流之流動進行說明。分別以箭頭U表示主空氣之流動，以箭頭V表示燃料氣體之流動，以箭頭W表示混合氣體之流動，以箭頭X表示次空氣之流動，以箭頭Y1表示從內周火焰孔18c噴出之火焰之流動，以箭頭Y2表示從外周火焰孔18d噴出之火焰之流動，以箭頭Z表示熱氣流之流動。【54】 從風扇27送風之空氣之一部分，作為主空氣U，而強制性地從燃燒器17之主空氣導入口20e、及燃料氣體導入口20d與氣體噴嘴24之間隙20f往供給管20內部導入。導入至供給管20內部之燃料氣體V與主空氣U，在供給管20內部混合且成為混合氣體W。然後，混合氣體W，於雙層圓筒部18內部之空間19上升，而從內周火焰孔18c及外周火焰孔18d噴出。【55】 從內周火焰孔18c及外周火焰孔18d噴出之混合氣體W，由點火源(未圖示)點火，且從內周火焰孔18c及外周火焰孔18d分別噴出火焰Y1及火焰Y2。【56】 此外，從風扇27送風之空氣之一部分，作為次空氣X，於次空氣流路23即燃燒器17之外筒部18b與周壁4e之間隙及內筒部18a內側上升。【57】 如同上述，使來自風扇27之送風，對供給管20內部強制性地導入來自風扇27之主空氣U，因此在內周火焰孔18c中，燃燒速度之一方較混合氣體W之噴出速度為快。其結果為，從複數個內周火焰孔18c噴出之各個火焰Y1之火力範圍，與未對供給管20內部強制性地導入主空氣U之情形相比較，變較小。一般而言，火焰具有一旦火焰彼此相碰撞則火力範圍將激烈地變大之性質。而且，於內筒部18a，由於在圓周方向設置有複數個內周火焰孔18c，因此從各個內周火焰孔18c噴出之火焰Y1彼此處於容易碰撞之狀況。然而，在本發明中，由於使從各個內周火焰孔18c噴出之各個火焰Y1之火力範圍變較小，因此使火焰Y1彼此相互碰撞之情況變少。此外，藉由於內筒部18a內側上升之次空氣，使從各個內周火焰孔18c噴出之火焰Y1改變方向往上方，使火焰Y1彼此相互碰撞之情況進一步變少。因此，不會有從內周火焰孔18c噴出之火焰Y1之火力範圍變大之情況，且使火焰Y1不會直接接觸直接設置於鍋載置部5a上之鍋P。【58】 進一步地，藉由往圓筒部18a內側供給之次空氣X，由從內周火焰孔18c噴出之火焰Y1加熱過之熱氣流Z，從熱板15內與熱板15之中央開口部15a往上部之鍋載置部5a進行分流，因此，使熱未集中於鍋載置部5a而分散。其結果為，藉由將鍋載置部5a之加熱變弱，可使鍋載置部5a之溫度下降。藉此，可抑制載置於鍋載置部5a之鍋P過熱、抑制鍋P內之液體過度沸騰。【59】 此外，藉由往圓筒部18a內側強制性地供給次空氣X，從內周火焰孔18c噴出之火焰Y1，促進燃燒，藉由熱板15分流，傳遞於熱板15之下面而往熱板15之外周流動。而且，由從內周火焰孔18c噴出之火焰Y1所產生之熱氣流Z，從熱板15之開口15b或熱板15之外周緣部往上方噴出，對網體5b進行加熱。其結果為，設置於中央部之鍋載置部5a之加熱變弱而溫度下降，另一方面，維持設置於鍋載置部5a之周圍之網體5b之加熱。【60】 此外，往外筒部18b與周壁4e之間隙強制性地供給次空氣X，藉此，藉由該上升之次空氣X之吸引誘導而將熱板15內之熱氣流Z導往熱板15之外周緣部，並且從外周火焰孔噴出之火焰Y2亦往熱板15之外周流動。此處，載置於周壁4e上之熱板承載件16之載置台16b，具有較周壁4e更為小徑之中央開口部16a，因此使外筒部18b與載置台16b之間隙，較外筒部18b與周壁4e之間隙狹小。因此，上升之次空氣X之吸引誘導作用變更強，加速熱氣流Z之往熱板15之外周緣部之流動。而且，熱氣流Z從熱板15之外周緣部往上方噴出，對網體5b進行加熱。進一步地，由於主要藉由主空氣U之供給而使燃燒狀態良好地進行，因此經增加發熱量之狀態之熱氣流Z以往熱板15內分流之狀態導往熱板15之外周緣部。其結果為，可維持網體5b之加熱、防止網體5b之溫度下降。【61】 主空氣或次空氣之供給量，藉由從風扇27送風之風量或利用調節氣閘25變更主空氣導入口20e之開口度，而可進行調節。而且，藉由調節主空氣或次空氣之供給量，而可調節從內周火焰孔18c及外周火焰孔18d噴出之火焰之火力範圍之大小、或熱氣流之流速等。其結果為，可調節鍋載置部5a或網體5b之溫度。【62】 另外，在未進行從風扇27之送風之情形，主空氣，藉由文土里效應，而僅由主空氣導入口20e、及燃料氣體導入口20d與氣體噴嘴24之間隙20f自然吸引(自然給氣)。此外，次空氣亦僅藉由從內周火焰孔18c及外周火焰孔18d噴出之火焰消耗周圍之空氣而產生自然吸引(自然給氣)。然而，在本發明中，藉由風扇27進行送風，藉此強制性地供給主空氣及次空氣，因此可得如上述般之效果。【63】 此外，在本發明中，熱板承載件16之引導壁16c，構成為圍繞外周火焰孔18d。因此，由從外周火焰孔18d噴出之火焰Y2加熱過之熱氣流Z，藉由引導壁16c導往上方，從熱板15之外周緣部與引導壁16c之間噴出，對網體5b進行加熱。其結果為，可防止網體5b之溫度下降。【64】 進一步地，引導壁16b，構成為圍繞外周火焰孔18d，藉此可抑制從外周火焰孔18d噴出之火焰Y2直接接觸側壁4a而使內箱4過熱。其結果為，亦可防止由從網體5b往側壁4a滴下之肉汁等造成之污垢燒焦。【實施例】【65】 [實施例1] 利用圖1所示之加熱調理器1，以進行了從風扇27送風之情形與未進行之情形，進行從燃燒器17噴出之火焰之火力範圍之大小的比較。另外，比較方法係以目視進行。【66】 其結果為，確認了如下情況：在未進行從風扇27送風之情形，從內周火焰孔18c噴出之火焰，從熱板15之中央開口部15a噴出，該火焰接觸鍋P之鍋底下面，而且在火焰往左右分流之過程中火焰延伸。相對於此，在進行了從風扇27強制送風之情形，從內周火焰孔18c噴出之火焰，未從熱板15之中央開口部15a噴出，而與未進行從風扇27送風之情形相比較，可知從內周火焰孔18c噴出之火焰之火力範圍明顯變小。【67】 [實施例2] 接著，在將注入有水之鍋P載置於調理部5之鍋載置部5a之狀態下進行加熱，比較從風扇27強制送風之與否導致的鍋載置部5a與網體5b之溫度變化、或鍋P內之水之沸騰狀態。溫度變化，係利用設置於鍋載置部5a及網體5b之熱電偶(thermocouple)進行溫度測定。鍋P內之水之沸騰狀態，係以目視進行觀察。【68】 首先，從加熱開始至10分為止以強火進行加熱，使鍋P內之水沸騰。之後，從10分至20分為止將火力降為中火，且不進行從風扇27送風而進行加熱。從20分至30分為止以維持中火之狀態，且一邊進行從風扇27送風一邊進行加熱。【69】 圖12係以橫軸為時間(分)、以縱軸為溫度(°C)之方式表示從加熱開始至30分為止之鍋載置部5a與網體5b之溫度變化之圖。圖中之30表示鍋載置部5a之溫度變化，31表示網體5b之溫度變化。(1)從加熱時間10分至20分為止之結果(火力：中火；從風扇送風：無)：可知藉由將火力從強火降為中火，使鍋載置部5a及網體5b之溫度一起下降。但是，可確認鍋載置部5a之溫度並未如此程度降低，而鍋P內之水過度沸騰。此外，藉由將火力降為中火，網體5b之溫度較網體加熱適當溫度為低。(2)從加熱時間20分至30分為止之結果(火力：中火；從風扇送風：有)：藉由在火力維持中火之狀態下進行從風扇27之送風，可使鍋載置部5a之溫度更下降，此時鍋P內之水並未有過度沸騰之情況。另一方面，網體5b之溫度相較於從加熱時間10分至20分為止之情形上升，可維持於網體加熱適當溫度附近。【70】 如此般，藉由從風扇27進行強制性地送風，即使是將火力降為中火之情形，亦可維持網體5b之溫度，同時使鍋載置部5a之溫度下降，因此可防止鍋P內之水過度沸騰。【71】 [其他之實施形態] 在上述之實施形態中，雖已針對以鍋載置部5a構成中央部、以網體5b構成鍋載置部5a之外周部的調理部5進行了說明，但調理部5之構成並不限定於此。例如，亦可在以調理部5之中央部設為第一調理部、以第一調理部之外周部設為第二調理部之情形，以鐵板載置部或烤爐載置部構成第一調理部、以網體構成第二調理部。此外，亦可以鍋載置部構成第一調理部、以鐵板或烤爐構成第二調理部。另外，亦可僅以鐵板、烤爐或網體構成調理部5。【72】 本發明不限於上述實施形態，可在不脫離本發明之趣旨之範圍內適當地做變更。【73】 本發明不限於以鍋載置部構成中央部、以網體構成鍋載置部之周圍的加熱調理器般之可以一台同時進行2種類以上之調理的加熱調理器，例如，可廣泛地利用於使加熱對象物之中央部之加熱變弱、且維持加熱對象物之外周部之加熱般之可改變加熱對象物之中央部與外周部之加熱之強弱的加熱調理器。[23] Embodiments of the

A step 22e which is inclined downward is formed on the inner wall of the burner head outer tubular portion 22b. Further, the upper portion of the mixing space 22c is closed by a lid portion 22f that integrally constitutes the burner head inner tubular portion 22a and the burner head outer tubular portion 22b. In the upper portion of the burner head outer cylinder portion 22b, a plurality of circumferentially facing outer peripheral flame holes 18d are formed in the circumferential direction; and the lower end surface 22g of the burner head inner tubular portion 22a is disposed in the circumferential direction obliquely upward toward the inner side. There are a plurality of grooves 22h. As described above, the burner 17, as shown in Fig. 5, is formed in such a manner that the burner head 22 is attached to the burner body 21. Specifically, the notched portion 22d of the burner head 22 is located on the inclined portion 21d of the burner body 21, and the burner head 22 is embedded in the burner body 21. At this time, the upper end surface 21f of the burner inner cylinder portion 21a and the lower end surface 22g of the burner head inner cylinder portion 22a, and the upper end surface 21g of the burner inner and outer cylinder portion 21b and the burner head outer cylinder portion 22b are disposed. The step difference 22e of the inner wall is abutted separately. The plurality of grooves 22h formed on the lower end surface 22g of the inner portion 22a of the burner head are formed by abutting the upper end surface 21f of the inner tubular portion 21a of the burner body against the lower end surface 22g of the inner portion 22a of the burner head. It is an inner peripheral flame hole 18c. In this manner, the burner body inner cylinder portion 21a and the burner head inner cylinder portion 22a constitute the inner cylindrical portion 18a of the double cylindrical portion 18 of the burner 17, and the burner outer cylinder portion 21b and the burner The head outer tubular portion 22b constitutes the outer tubular portion 18b of the double cylindrical portion 18 of the burner 17, and the mixing space 21c of the burner body 21 and the mixing space 22c with the burner head 22 constitute a space 19 of the burner 17. As described above, in the present embodiment, the burner 17 is configured to disassemble the burner body 21 and the burner head 22, so that the cleaning of the burner 17 is facilitated. Further, the burner 17 may be configured such that the burner body 21 and the burner head 22 are not disassembled, and the burner body 21 and the burner head 22 are integrally formed. Further, the supply pipe 20 is not limited to a configuration that extends downward from the outer circumferential surface of the outer tubular portion 21 of the burner, and may be configured to extend horizontally from the outer tubular portion 21 of the burner. As shown in Fig. 6(b), the inside of the supply pipe 20 of the burner 17 has a narrowed portion 20c between the communicating portion 20b and the inflow port 20a. Specifically, the inner diameter is continuously reduced from the communication portion 20b to the narrow portion 20c inside the supply tube 20, and the inner diameter is continuously expanded from the narrow portion 20c toward the inflow port 20a. The inside of the supply pipe 20 is configured as described above, and when the fuel gas is supplied inside the supply pipe 20, the main air is sucked into the supply pipe 20 by the Venturi effect. As shown in Fig. 6(c), the inflow port 20a formed in the bottom surface of the supply pipe 20 is mainly formed of a fuel gas introduction port 20d for introducing a circular opening of the fuel gas, and a fuel gas introduction port 20d. The main air introduction port 20e having a fan shape opening around it is formed. The gas nozzle 24 is inserted into the fuel gas introduction port 20d, and the fuel gas is supplied from the gas nozzle 24 to the inside of the supply pipe 20. Since the fuel gas introduction port 20d is formed to have a larger diameter than the outer diameter of the gas nozzle 24, a gap 20f is formed between the fuel gas introduction port 20d and the gas nozzle 24 as shown in Fig. 1 . Therefore, the main air is introduced from the gap 20f in addition to the main air introduction port 20e. Fig. 8(a) is a plan view showing an adjustment damper 25, and Fig. 8(b) is a cross-sectional view showing the D-D arrow of the damper 25 in Fig. 8(a). On the bottom surface of the supply pipe 20, an adjustment damper 25 for adjusting the supply amount of the main air introduced from the main air introduction port 20e is installed. The damper 25 is adjusted to be rotatable about the axis of the supply pipe 20. The damper 25 includes a circular opening portion 25a which is formed of a crown member and has substantially the same diameter as the fuel gas introduction port 20d, a fan-shaped opening portion 25b formed around the circular opening portion 25a, and a circular opening. The shielding area 25c which is a region around the portion 25a where the fan-shaped opening portion 25b is not formed is formed. In addition, FIG. 8 illustrates a case where two fan-shaped openings 25b are formed. The damper 25 is attached to the bottom surface of the supply pipe 20 so that the axis of the circular opening portion 25a coincides with the axis of the fuel gas introduction port 20d. Further, the fan-shaped opening 25b is provided at a position corresponding to the main air introduction port 20e in the radial direction when the adjustment air lock 25 has been attached to the bottom surface of the supply pipe 20. [48] The supply amount of the main air is performed by adjusting the opening degree of the main air introduction port 20e by rotating the adjustment air lock 25. In other words, when the main air introduction port 20e and the fan-shaped opening 25b come to a position where they overlap, the opening degree of the main air introduction port 20e is maximized, and the supply amount of the main air is also maximized. Further, in a case where the supply amount of the main air is to be made small, the adjustment air brake 25 is rotated to position the shielding region 25c on the main air introduction port 20e, that is, the shielding region 25c is closed by the main air introduction port 20e. The opening of the main air introduction port 20e is adjusted in such a manner that the opening degree becomes small. When the position of the air brake 25 is adjusted, the adjustment air lock 25 is fixed to the bottom surface of the supply pipe 20 by fastening means such as screws. In this manner, the supply amount of the main air introduced from the main air introduction port 20e can be adjusted. 9(a) is a plan view showing the casing 26, and FIG. 9(b) is a left side view showing the casing 26. A casing 26 is disposed below the inner casing 4, and a fan 27 (an example of a blowing means) is disposed in the casing 26. An air volume adjusting means 28 for adjusting the air volume is provided at the inlet of the wind of the fan 27 outside the casing 26. The air volume adjusting means 28 in the present embodiment is constituted by a plate-like member provided with a plurality of long hole-shaped openings, and the air volume can be adjusted by adjusting the opening area of the long hole-shaped opening. In addition, the air volume adjusting means 28 is not limited to the above-described configuration in which the plate-like member is attached to the inlet of the wind of the fan 27, and may be, for example, a control means for changing the electrical conductivity of the number of rotations of the blades of the fan 27. Further, the fan 27 does not necessarily have to be provided in the casing 26. For example, the fan 27 may be provided outside the casing 26, and the fan 27 and the casing 26 may be connected to the pipe to supply the wind into the casing 26. [50] The upper surface of the casing 26 has a plurality of openings 26a communicating with the bottom opening portion 4d of the inner casing 4. One of the plurality of openings 26a is for inserting into the opening 26b of the supply tube 20 of the burner 17, and is formed to have a larger diameter than the outer diameter of the lower end portion of the supply tube 20. Fig. 10 is a plan view showing the receiving tray 29. On the upper surface of the casing 26, a receiving vessel 29 is placed; the receiving vessel 29 has a diameter equal to that of the opening 26b (that is, a larger diameter than the outer diameter of the lower end of the supply pipe 20). 29a, an arcuate opening 29b, and a projection insertion opening 29c into which the projection 21h of the burner 17 is inserted. The receiving vessel 29 is placed on the upper surface of the casing 26 such that the axial center of the supply pipe insertion opening 29a coincides with the axis of the opening 26b. Further, when the supply pipe 20 is inserted into the supply pipe insertion port 29a, the projection 21h of the burner 17 is fitted into the projection insertion opening 29c, whereby the burner 17 is supported by the receiving vessel 29. At this time, the gas nozzle 24 provided at the bottom of the casing 26 is inserted into the fuel gas introduction port 20d. [52] The opening 26b is larger than the outer diameter of the supply pipe 20, so that a gap is formed between the opening 26b and the supply pipe 20. Therefore, the secondary air supplied from the fan 27 rises in the gap or opening 26a. Further, since the supply pipe insertion port 29a has a larger diameter than the outer diameter of the supply pipe 20, a gap is also formed between the supply pipe insertion port 29a and the supply pipe 20. Therefore, the secondary air passes through the gap or the arc-shaped opening 29b, and then rises inside the inner cylindrical portion 18a of the double-layered cylindrical portion 18 and between the outer cylindrical portion 18b and the peripheral wall 4e. Figure 11 is a schematic diagram showing the flow of primary air, fuel gas, mixed gas, secondary air, flame, and hot gas flow. The flow of the main air, the fuel gas, the mixed gas, the secondary air, the flame, and the hot gas flow will be described with reference to Fig. 11 . The flow of the main air is indicated by an arrow U, the flow of the fuel gas by the arrow V, the flow of the mixed gas by the arrow W, the flow of the secondary air by the arrow X, and the flame ejected from the inner peripheral flame hole 18c by the arrow Y1. In the flow, the flow of the flame ejected from the outer peripheral flame hole 18d is indicated by an arrow Y2, and the flow of the hot air flow is indicated by an arrow Z. [54] A portion of the air blown from the fan 27 is forcibly discharged from the main air introduction port 20e of the burner 17 and the gap 20f between the fuel gas introduction port 20d and the gas nozzle 24 to the inside of the supply pipe 20 as the main air U. Import. The fuel gas V introduced into the inside of the supply pipe 20 and the main air U are mixed in the supply pipe 20 to become the mixed gas W. Then, the mixed gas W rises in the space 19 inside the double-layered cylindrical portion 18, and is ejected from the inner peripheral flame hole 18c and the outer peripheral flame hole 18d. The mixed gas W ejected from the inner peripheral flame hole 18c and the outer peripheral flame hole 18d is ignited by an ignition source (not shown), and the flame Y1 and the flame Y2 are ejected from the inner peripheral flame hole 18c and the outer peripheral flame hole 18d, respectively. In addition, part of the air blown from the fan 27 as the secondary air X rises in the gap between the cylindrical portion 18b and the peripheral wall 4e and the inner side of the inner tubular portion 18a in the secondary air flow path 23, that is, the burner 17. As described above, the air blown from the fan 27 is forcibly introduced into the main air U from the fan 27 to the inside of the supply pipe 20, so that one of the combustion speeds in the inner peripheral flame hole 18c is higher than the discharge speed of the mixed gas W. Fast. As a result, the range of the heating force of each of the flames Y1 ejected from the plurality of inner peripheral flame holes 18c becomes smaller as compared with the case where the main air U is not forcibly introduced into the supply pipe 20. In general, the flame has the property that the range of the fire force will become drastically large once the flames collide with each other. Further, since the inner cylindrical portion 18a is provided with a plurality of inner peripheral flame holes 18c in the circumferential direction, the flames Y1 ejected from the respective inner peripheral flame holes 18c are likely to collide with each other. However, in the present invention, since the range of the fire force of each of the flames Y1 ejected from the respective inner peripheral flame holes 18c is made small, the flame Y1 collides with each other. In addition, the flame Y1 ejected from each inner peripheral flame hole 18c is redirected upward by the secondary air rising inside the inner cylinder portion 18a, and the flame Y1 collides with each other further. Therefore, the range of the fire force of the flame Y1 ejected from the inner peripheral flame hole 18c does not become large, and the flame Y1 does not directly contact the pan P directly provided on the pan placing portion 5a. Further, the hot air flow Z heated by the flame Y1 ejected from the inner peripheral flame hole 18c is opened from the center of the hot plate 15 and the hot plate 15 by the secondary air X supplied to the inside of the cylindrical portion 18a. Since the portion 15a is branched to the upper pot placing portion 5a, the heat is not concentrated on the pot placing portion 5a and dispersed. As a result, the temperature of the pan placing portion 5a can be lowered by weakening the heating of the pan placing portion 5a. Thereby, it is possible to suppress overheating of the pan P placed on the pan placing portion 5a and to suppress excessive boiling of the liquid in the pan P. Further, by forcibly supplying the secondary air X to the inside of the cylindrical portion 18a, the flame Y1 ejected from the inner peripheral flame hole 18c promotes combustion, is shunted by the hot plate 15, and is transmitted to the lower surface of the hot plate 15. It flows to the outside of the hot plate 15. Then, the hot gas flow Z generated by the flame Y1 ejected from the inner peripheral flame hole 18c is ejected upward from the outer periphery of the hot plate 15 or the outer periphery of the hot plate 15, and the net body 5b is heated. As a result, the heating of the pot placing portion 5a provided at the center portion is weakened and the temperature is lowered, and the heating of the net body 5b provided around the pot placing portion 5a is maintained. Further, the secondary air X is forcibly supplied to the gap between the outer tubular portion 18b and the peripheral wall 4e, whereby the hot gas flow Z in the hot plate 15 is guided to the hot plate by the suction induction of the rising secondary air X. The flame Y2 which is ejected from the outer peripheral flame hole is also flowed to the outer periphery of the hot plate 15. Here, the mounting table 16b of the hot plate carrier 16 placed on the peripheral wall 4e has a central opening 16a having a smaller diameter than the peripheral wall 4e, so that the gap between the outer cylindrical portion 18b and the mounting table 16b is larger than that of the outer cylinder The gap between the portion 18b and the peripheral wall 4e is narrow. Therefore, the suction induction effect of the rising air X is changed strongly, and the flow of the hot air flow Z to the outer peripheral portion of the hot plate 15 is accelerated. Further, the hot air flow Z is discharged upward from the outer peripheral portion of the hot plate 15, and the net body 5b is heated. Further, since the combustion state is favorably performed mainly by the supply of the main air U, the hot gas flow Z in a state in which the amount of heat generation is increased is guided to the outer peripheral portion of the hot plate 15 in the state of being branched in the hot plate 15 in the past. As a result, the heating of the net body 5b can be maintained, and the temperature of the net body 5b can be prevented from dropping. [61] The supply amount of the main air or the secondary air can be adjusted by changing the air volume of the air blown from the fan 27 or changing the opening degree of the main air introduction port 20e by the adjustment air lock 25. Further, by adjusting the supply amount of the primary air or the secondary air, the range of the fire force of the flame ejected from the inner peripheral flame hole 18c and the outer peripheral flame hole 18d, or the flow velocity of the hot gas flow can be adjusted. As a result, the temperature of the pan placing portion 5a or the net body 5b can be adjusted. Further, in the case where the air blow from the fan 27 is not performed, the main air is naturally attracted only by the main air introduction port 20e and the gap 20f between the fuel gas introduction port 20d and the gas nozzle 24 by the effect of the soil. (naturally gas). Further, the secondary air also generates natural attraction (natural gas supply) only by consuming the surrounding air from the flame ejected from the inner peripheral flame hole 18c and the outer peripheral flame hole 18d. However, in the present invention, the air is blown by the fan 27, whereby the main air and the secondary air are forcibly supplied, so that the above-described effects can be obtained. Further, in the present invention, the guide wall 16c of the hot plate carrier 16 is configured to surround the outer peripheral flame hole 18d. Therefore, the hot air current Z heated by the flame Y2 ejected from the outer peripheral flame hole 18d is guided upward by the guide wall 16c, and is ejected from the outer peripheral edge portion of the hot plate 15 and the guide wall 16c to heat the net body 5b. . As a result, the temperature of the net body 5b can be prevented from dropping. Further, the guide wall 16b is configured to surround the outer peripheral flame hole 18d, whereby the flame Y2 ejected from the outer peripheral flame hole 18d can be prevented from directly contacting the side wall 4a to overheat the inner box 4. As a result, it is possible to prevent the scorching of the dirt caused by the gravy or the like dripped from the net body 5b to the side wall 4a. [Embodiment] [65] [Embodiment 1] Using the heating conditioner 1 shown in Fig. 1, the range of the fire force of the flame ejected from the burner 17 is performed in the case where the air is blown from the fan 27 and the case where it is not performed. Comparison of size. In addition, the comparison method was performed visually. As a result, it was confirmed that the flame ejected from the inner peripheral flame hole 18c was ejected from the central opening 15a of the hot plate 15 when the air was blown from the fan 27, and the flame contacted the bottom of the pan P Below, and the flame extends during the splitting of the flame to the left and right. On the other hand, in the case where forced air is blown from the fan 27, the flame ejected from the inner peripheral flame hole 18c is not ejected from the central opening 15a of the hot plate 15, and is compared with the case where the air is not blown from the fan 27, It can be seen that the range of the fire force of the flame ejected from the inner peripheral flame hole 18c is remarkably small. [Example 2] Next, the pot P in which the water is poured is placed in the state of the pot placing portion 5a of the conditioning unit 5, and the pot is placed in comparison with the forced blowing of the fan 27. The temperature of the portion 5a and the net body 5b changes, or the boiling state of the water in the pot P. The temperature change was measured by a thermocouple provided on the pan placing portion 5a and the net body 5b. The boiling state of the water in the pot P was observed by visual observation. [68] First, heat is heated by a strong fire from the start of heating to 10 minutes to boil the water in the pot P. Thereafter, the firepower is reduced to a medium fire from 10 minutes to 20 minutes, and heating is not performed by blowing air from the fan 27. The state of the medium fire is maintained from 20 minutes to 30 minutes, and heating is performed while blowing air from the fan 27. [Fig. 12] Fig. 12 is a diagram showing changes in temperature of the pot placing portion 5a and the net body 5b from the start of heating to 30 minutes, with the horizontal axis being time (minutes) and the vertical axis being temperature (°C). In the figure, 30 indicates a temperature change of the pan placing portion 5a, and 31 indicates a temperature change of the net body 5b. (1) Results from the heating time of 10 minutes to 20 minutes (firepower: medium fire; air supply from the fan: none): It can be seen that the pot placing portion 5a and the net body 5b are made by reducing the fire power from a strong fire to a medium fire. The temperature drops together. However, it was confirmed that the temperature of the pan placing portion 5a was not lowered to such an extent that the water in the pan P was excessively boiled. In addition, by reducing the firepower to medium fire, the temperature of the net body 5b is lower than the appropriate temperature for heating the net body. (2) Results from the heating time of 20 minutes to 30 minutes (firepower: medium fire; air supply from the fan: yes): The air can be supplied from the fan 27 by maintaining the medium fire in the state of fire. The temperature of 5a is even lower, and the water in the pot P does not excessively boil. On the other hand, the temperature of the net body 5b rises in comparison with the case of heating from 10 minutes to 20 minutes, and can be maintained in the vicinity of the appropriate temperature for heating the net body. [70] In this manner, by forcibly blowing air from the fan 27, even if the firepower is reduced to a medium fire, the temperature of the net body 5b can be maintained and the temperature of the pan placing portion 5a can be lowered. Prevent the water in the pot P from boiling too much. [Others] In the above-described embodiment, the conditioning unit 5 in which the central portion is formed by the pot placing portion 5a and the outer peripheral portion of the pot placing portion 5a is formed by the net body 5b has been described. However, the configuration of the conditioning unit 5 is not limited to this. For example, in the case where the central portion of the conditioning unit 5 is the first conditioning unit and the outer portion of the first conditioning unit is the second conditioning unit, the iron plate mounting portion or the oven mounting portion may be configured. A conditioning unit and a second conditioning unit are formed by a network body. Further, the pot placing portion may constitute the first conditioning portion, and the second conditioning portion may be formed by an iron plate or an oven. Further, the conditioning unit 5 may be constituted only by an iron plate, an oven or a mesh body. The present invention is not limited to the above-described embodiments, and may be appropriately modified without departing from the spirit and scope of the invention. [73] The present invention is not limited to a heating conditioner in which two or more types of conditioning can be performed at the same time, in which a central portion is formed by a pot placing portion and a heating device around the pot placing portion is formed by a net body, for example, It is widely used as a heating conditioner that weakens the heating of the central portion of the object to be heated and maintains the heating of the outer peripheral portion of the object to be heated, thereby changing the heating intensity of the central portion and the outer peripheral portion of the object to be heated.
