Description
本発明は、コンロの天板から露出させて五徳上の鍋等を加熱するコンロ用バーナ、及び、このバーナを備えたコンロに関する。 The present invention relates to a stove burner that is exposed from a top plate of a stove and heats a pan on the virtues, and a stove provided with the burner.
コンロに設けられ、コンロの天板に設けられた五徳上の鍋等を加熱するコンロ用バーナは、一般に、燃料ガスと一次空気とを混合する混合管に連設されたバーナヘッド上にバーナキャップが載置されている。バーナヘッドには、外周縁に沿って筒状に起立する周壁が形成されており、周壁の内側に混合管に連通する分布室が形成され、周壁の環状の上端面がバーナキャップの座面とされている。 A burner for a stove that is provided on a stove and that heats a pot on a virtue provided on the top plate of the stove is generally a burner cap on a burner head that is connected to a mixing tube that mixes fuel gas and primary air. Is placed. The burner head has a peripheral wall that rises in a cylindrical shape along the outer peripheral edge, a distribution chamber that communicates with the mixing tube is formed inside the peripheral wall, and the annular upper end surface of the peripheral wall is the seat surface of the burner cap. Has been.
バーナキャップの外周縁の全周には垂下する環状壁が形成されている。環状壁には複数の溝が周方向に所定間隔を存して複数設けられ、バーナキャップの環状壁をバーナヘッドの周壁の座面に着座させると、複数の炎口が形成される。 A hanging annular wall is formed on the entire outer periphery of the burner cap. A plurality of grooves are provided in the annular wall at predetermined intervals in the circumferential direction, and a plurality of flame openings are formed when the annular wall of the burner cap is seated on the seating surface of the peripheral wall of the burner head.
しかし、鍋等から溢れた煮汁がバーナキャップ上にこぼれると、炎口からバーナヘッドの内部へ煮汁が侵入することがある。そこで、従来、バーナキャップを載置するための座面を、バーナヘッドの中心に向けて次第に高くなるような傾斜面としたものが知られている（例えば特許文献１参照）。このものでは更に、環状壁の上端の近傍に、外端の炎口に向かって上昇する炎口用通路が貫通し、環状壁の下面には煮汁戻し溝が形成されている。 However, when spilled sap overflows from the pan etc. onto the burner cap, the simmered broth may enter the burner head from the flame outlet. Therefore, conventionally, a seat surface on which the burner cap is placed is known as an inclined surface that gradually increases toward the center of the burner head (see, for example, Patent Document 1). In this case, a flame passage for rising toward the flame mouth at the outer end penetrates in the vicinity of the upper end of the annular wall, and a boiled return groove is formed on the lower surface of the annular wall.
しかし、鍋からの煮こぼれが激しい場合は、煮汁が炎口内部に入り込む等によってバーナヘッドの内部中心方向に勢いよく流れてしまい、これにより、煮汁が分布室内や混合管内に侵入するという問題があった。 However, if the spilling from the pan is intense, the broth will flow vigorously toward the inner center of the burner head due to entering the inside of the flame outlet, etc., which causes the problem that the broth enters the distribution chamber or mixing tube. there were.
そこで、本出願人は、先に、煮汁の分布室内や混合管内への侵入を防止したコンロ用バーナを提案した（特許文献２参照）。 In view of this, the present applicant has previously proposed a stove burner that prevents the broth from entering the distribution chamber or the mixing tube (see Patent Document 2).
ところで、コンロにおいて五徳上の鍋をバーナで加熱するとき、鍋底に対してバーナの火炎が垂直に近い姿勢で下方から当たるようにすることで、最も効率よく鍋を加熱することができることは周知である。 By the way, it is well known that when a pan on the virtues is heated with a burner on the stove, the pan can be heated most efficiently by making the flame of the burner strike from the bottom in a posture that is nearly vertical to the bottom of the pan. is there.
上記特許文献２のバーナの各炎口は、バーナキャップの傾斜する上面から上向きに開口して放射状に延びているものの、バーナキャップの外周縁では水平方向に開口する部分に連続する構成となっている。 Although each flame mouth of the above-mentioned burner of Patent Document 2 opens upward from the inclined upper surface of the burner cap and extends radially, the outer peripheral edge of the burner cap has a configuration that continues to a portion that opens horizontally. Yes.
このため、各炎口で形成される火炎は、特に強火のとき、バーナキャップの外周縁から横方向に放射状に形成され、鍋底等に火炎が斜めに当たるために、十分な加熱効率が得られない不都合があった。 For this reason, the flame formed at each flame mouth is formed in a radial direction from the outer periphery of the burner cap, particularly in the case of a strong fire, and the flame hits the bottom of the pan diagonally, so that sufficient heating efficiency cannot be obtained. There was an inconvenience.
上記の点に鑑み、本発明は、炎口からの煮汁の侵入によるガス流路の閉塞を防止しながら、被加熱物に対して高い加熱効率が得られるコンロ用バーナ及びコンロを提供することを目的とする。 In view of the above points, the present invention provides a stove burner and a stove that can obtain high heating efficiency with respect to an object to be heated while preventing blockage of a gas flow path due to intrusion of boiled juice from a flame outlet. Objective.
かかる目的を達成するために、本発明のコンロ用バーナは、燃料ガスと一次空気とを混合して混合ガスを生成する混合管と、該混合管の下流に連通する混合ガスの分布室を備えるバーナヘッドと、該バーナヘッド上に載置されて前記分布室から供給する混合ガスにより火炎を形成する複数の炎口が形成されたバーナキャップとを備え、前記バーナキャップは、外周縁から中央部に向って次第に高くなる傾斜面を上面とする傘状に形成されて当該上面に前記各炎口を備え、前記各炎口は、前記バーナキャップの上面の外周縁から所定の距離を存した位置に形成され、前記分布室は、環状で上向きに開放されて前記各炎口よりも中央側の前記バーナキャップの下面に対向していることを特徴とする。 In order to achieve such an object, the stove burner of the present invention includes a mixing tube that mixes fuel gas and primary air to generate a mixed gas, and a mixed gas distribution chamber that communicates downstream of the mixing tube. A burner head, and a burner cap formed on the burner head and formed with a plurality of flame openings for forming a flame by a mixed gas supplied from the distribution chamber, the burner cap being arranged from the outer peripheral edge to the central portion The upper surface of each flame outlet is formed in an umbrella shape having an inclined surface that gradually increases toward the upper surface, and each flame outlet is located at a predetermined distance from the outer peripheral edge of the upper surface of the burner cap. The distribution chamber is formed in an annular shape, opened upward, and opposed to the lower surface of the burner cap on the center side of each flame port.
本発明によれば、傘状に形成されたバーナキャップの上面に、バーナキャップの外周縁から所定の距離を存して炎口を設けたので、炎口は上向きに開口し、火炎が上向きに形成される。従って、炎口の上方にある被加熱物に対して火炎が略垂直に当たるので、被加熱物に対して高い加熱効率を得ることができる。 According to the present invention, since the flame opening is provided on the upper surface of the burner cap formed in an umbrella shape at a predetermined distance from the outer peripheral edge of the burner cap, the flame opening opens upward and the flame faces upward. It is formed. Therefore, since the flame hits the object to be heated above the flame opening substantially perpendicularly, high heating efficiency can be obtained for the object to be heated.
しかも、環状の分布室の上向きに開放された部分の直上には炎口が位置せず、炎口からバーナ内に煮汁が流下しても、分布室に侵入することがない。 In addition, the flame outlet is not located directly above the upwardly open portion of the annular distribution chamber, and even if the broth flows down from the flame into the burner, it does not enter the distribution chamber.
また、本発明のコンロ用バーナにおいて、前記バーナキャップは、前記各炎口の内周縁に沿って該バーナキャップの上面から***する***部を備えることが好ましい。これによれば、鍋等からバーナキャップの上面に煮汁がこぼれ落ちたとき、煮汁が***部を乗り越えない限り、炎口に侵入することができないので、煮汁の炎口への侵入を抑止することができる。 In the stove burner of the present invention, it is preferable that the burner cap has a raised portion that rises from the upper surface of the burner cap along the inner peripheral edge of each flame port. According to this, when the broth spills from the pan or the like onto the upper surface of the burner cap, the broth cannot enter the flame outlet unless it passes over the raised portion, so that the penetration of the broth into the flame mouth can be suppressed. it can.
また、本発明のコンロ用バーナにおいて、前記バーナキャップは、前記各炎口の内周縁全周から下方に向って延びる筒状部を備えることが好ましい。万一煮汁が炎口から侵入した場合、煮汁は筒状部の内面を伝って炎口直下に案内されて筒状部の下縁で円滑に水切りされる。これにより、煮汁がバーナキャップの下面を伝って移動することがなく、分布室内や混合管内への煮汁の侵入を確実に防止することができる。 In the stove burner of the present invention, it is preferable that the burner cap includes a cylindrical portion extending downward from the entire inner peripheral edge of each flame mouth. In the unlikely event that the broth enters from the flame outlet, the broth is guided along the inner surface of the tubular portion and directly under the flame opening and smoothly drained at the lower edge of the tubular portion. Thereby, the broth does not move along the lower surface of the burner cap, and the broth can be surely prevented from entering the distribution chamber or the mixing tube.
また、本発明のコンロ用バーナにおいては、前記バーナキャップの前記各炎口の少なくとも直下を含む領域に、各炎口を介して落下する侵入物を受ける受け部を取り外し自在に設けることが好ましい。 Moreover, in the stove burner of the present invention, it is preferable that a receiving portion for receiving an intruding substance falling through each flame port is provided in a region including at least immediately below each flame port of the burner cap.
これによれば、炎口から流れ落ちた煮汁（炎口を介して落下した侵入物）を受け部によって比較的大量に受けることができるだけでなく、受け部を取り外して洗浄や掃除をすることでバーナを清潔に保つことができる。 According to this, not only is it possible to receive a relatively large amount of boiled juice that has flowed down from the flame outlet (invaders that have fallen through the flame mouth) by the receiving part, but also by removing the receiving part and cleaning and cleaning the burner Can be kept clean.
このとき更に、前記受け部は、その外周縁から全周に亘って起立して形成された筒状の起立壁を備え、該起立壁は、全周に亘って前記バーナキャップの下面側に気密に当接することが好ましい。これによれば、炎口の外側位置（バーナキャップの外周縁側）でバーナキャップとバーナヘッドとのシール性を得ることができ、分布室から炎口へ向かう燃料ガスの流れを確実に形成することができる。 At this time, the receiving portion further includes a cylindrical upright wall formed so as to stand up from the outer peripheral edge over the entire circumference, and the upright wall is airtight on the lower surface side of the burner cap over the entire circumference. It is preferable to abut. According to this, the sealability between the burner cap and the burner head can be obtained at the outer position of the flame mouth (outer peripheral edge side of the burner cap), and the flow of fuel gas from the distribution chamber toward the flame mouth can be surely formed. Can do.
また、本発明は、上記構成のコンロ用バーナと、該コンロ用バーナに対応するバーナ用開口が形成された天板と、該天板により上面が覆われる筐体とを備えるコンロにおいて、前記コンロ用バーナの前記バーナキャップは、前記バーナ用開口より外径が大とされ、前記天板のバーナ用開口は、その上面全部が前記バーナキャップによって覆われることを特徴とする。 Further, the present invention provides a stove comprising the above-described stove burner, a top plate in which a burner opening corresponding to the stove burner is formed, and a casing whose upper surface is covered by the top plate. The burner cap of the burner has a larger outer diameter than the burner opening, and the burner opening of the top plate is entirely covered with the burner cap.
本発明によれば、天板のバーナ用開口が、傘状に形成されたバーナキャップにより覆われるので、バーナ用開口からコンロ内部への異物の侵入（例えば、バーナ用開口からコンロ内部への煮汁の流入を防止することができる。 According to the present invention, the burner opening of the top plate is covered with the burner cap formed in an umbrella shape, so that foreign matter enters from the burner opening into the stove (for example, the broth from the burner opening to the stove inside) Inflow can be prevented.
また、本発明のコンロにおいて、前記天板には、前記バーナ用開口を囲うようにして五徳が載置され、前記バーナキャップは、その外周縁に、前記五徳の少なくとも一部と係合する係合部を備えることが好ましい。 Further, in the stove of the present invention, a virtues are placed on the top plate so as to surround the burner opening, and the burner cap is engaged with at least a part of the virtues on the outer peripheral edge thereof. It is preferable to provide a joint.
前記係合部によってバーナキャップに対する五徳の位置決めが確実に行われるので、鍋等の被加熱部の安定載置が行えるだけでなく、例えば、五徳とバーナキャップとの位置ずれが生じた場合の五徳爪の炎炙りによる加熱効率の低下を確実に防止することができる。 Since the positioning of the virtues with respect to the burner cap is surely performed by the engaging portion, not only can the heated portion such as a pan be stably placed, but also, for example, the virtues when the misalignment between the virtues and the burner cap occurs. A decrease in heating efficiency due to the burning of the nail can be reliably prevented.
本発明の一実施形態を図面に基づいて説明する。本実施形態のコンロは、その筐体は図示省略するが、図１に要部を示すように、天板１上に五徳２が載置され、五徳２が包囲する位置にコンロ用バーナ３を備えている。 An embodiment of the present invention will be described with reference to the drawings. Although the casing of the stove of the present embodiment is not shown in the figure, as shown in FIG. 1, the virtue 2 is placed on the top plate 1, and the stove burner 3 is placed at a position where the virtue 2 surrounds. I have.
コンロ用バーナ３は、図２に示すように、混合管４と、バーナヘッド５と、バーナキャップ６とを備えている。混合管４は、図外のガスノズルから噴出する燃料ガスと共に燃焼用一次空気を取り込んで混合ガスを生成する。混合管４の下流側にはバーナヘッド５が一体に連設されている。 As shown in FIG. 2, the stove burner 3 includes a mixing tube 4, a burner head 5, and a burner cap 6. The mixing tube 4 takes in the primary air for combustion together with the fuel gas ejected from a gas nozzle (not shown) to generate a mixed gas. A burner head 5 is integrally provided downstream of the mixing tube 4.
バーナヘッド５は、天板１に形成されたバーナ用開口１ａに対応して配置され、図示しないコンロ本体に支持部材を介して支持されている。 The burner head 5 is disposed corresponding to the burner opening 1a formed in the top plate 1, and is supported by a stove body (not shown) via a support member.
バーナヘッド５は、外側壁５１と内側壁５２とを備え、両側壁間に環状の分布室７が形成されている。分布室７は、内側壁５２に沿って環状で上向きに開放された開放部７１を備えている。開放部７１は、分布室７の上面の略外側半部を覆う上部壁５３の内側端縁から立ち上がる案内壁５４を備えている。分布室７は、混合管４の下流に連通して混合ガスを環状に分布させた後、開放部７１の案内壁５４に沿って混合ガスを上方に案内して拡散させる。上部壁５３には後述する環状の受け皿部材８（受け部）が載置されている。 The burner head 5 includes an outer wall 51 and an inner wall 52, and an annular distribution chamber 7 is formed between both side walls. The distribution chamber 7 includes an open portion 71 that is annularly opened upward along the inner wall 52. The open portion 71 includes a guide wall 54 that rises from the inner edge of the upper wall 53 that covers the substantially outer half of the upper surface of the distribution chamber 7. The distribution chamber 7 communicates downstream of the mixing tube 4 to distribute the mixed gas in an annular shape, and then guides and diffuses the mixed gas upward along the guide wall 54 of the opening 71. An annular tray member 8 (receiving portion), which will be described later, is placed on the upper wall 53.
バーナヘッド５の上部にはバーナキャップ６が取り付けられる。バーナキャップ６は、図２及び図３に示すように、外周縁から中央部に向って次第に高くなる傾斜面を上面とする傘状に形成されている。バーナキャップ６の上面には、周方向に所定間隔を存して配設された複数の炎口９が形成されている。炎口９は、バーナキャップ６の径方向に沿って長手の孔形状とされ、バーナキャップ６の外側縁から所定距離（本実施形態では炎口９の長手方向の寸法よりも大きい距離）を存した位置に上向きに開口している。 A burner cap 6 is attached to the upper part of the burner head 5. As shown in FIGS. 2 and 3, the burner cap 6 is formed in an umbrella shape having an inclined surface that gradually increases from the outer peripheral edge toward the center. A plurality of flame openings 9 are formed on the upper surface of the burner cap 6 at predetermined intervals in the circumferential direction. The flame port 9 has a shape of a long hole along the radial direction of the burner cap 6, and has a predetermined distance from the outer edge of the burner cap 6 (in this embodiment, a distance larger than the longitudinal dimension of the flame port 9). Open upward at the specified position.
このように、バーナキャップ６に設けた炎口９は、バーナキャップ６の外周縁から所定距離を存して、しかも上向きに開口しているから、炎口９から形成される火炎は起立状態に近い姿勢で五徳２上に載置した鍋底（図示しない）に当たる。これにより、外側方向に向かって斜めに形成される火炎が鍋底に当たるものに比べて加熱効率が高い。 In this way, the flame port 9 provided in the burner cap 6 is opened upward at a predetermined distance from the outer peripheral edge of the burner cap 6, and the flame formed from the flame port 9 is in an upright state. Hit the bottom of the pot (not shown) placed on Gotoku 2 with a close posture. Thereby, a heating efficiency is high compared with what the flame formed diagonally toward an outer side hits a pan bottom.
また、バーナキャップ６の中央部には、下方に延びる円形空間を形成する中央筒壁６１が連設されている。中央筒壁６１は、内側壁５２が径方向内方に延びて更に下方に連設された筒状壁５２ａの内側周面に気密に接して、混合ガスの漏れを防止する。 Further, a central cylindrical wall 61 that forms a circular space extending downward is continuously provided at the center of the burner cap 6. The central cylindrical wall 61 is in airtight contact with the inner peripheral surface of a cylindrical wall 52a that is provided with an inner wall 52 extending radially inward and continuous downward, thereby preventing mixed gas from leaking.
炎口９は、図２に示すように、分布室７の開放部７１よりも外側位置で且つ、受け皿部材８の直上位置となるように形成されている。 As shown in FIG. 2, the flame port 9 is formed at a position outside the open portion 71 of the distribution chamber 7 and directly above the tray member 8.
図１及び図２に示すように、バーナヘッド５の内側壁５２とバーナキャップ６の中央筒壁６１とによる中央部空間には、上下に貫通してコンロ用バーナ３の上方に突出する鍋底温度センサＳが設けられる。 As shown in FIGS. 1 and 2, in the central space defined by the inner side wall 52 of the burner head 5 and the central cylindrical wall 61 of the burner cap 6, the pan bottom temperature penetrating vertically and projecting above the stove burner 3. A sensor S is provided.
図３及び図４に示すように、バーナキャップ６には、炎口９の内周縁に沿って***する***部６２が形成されている。更に、図４に示すように、炎口９の内周縁全周から下方に向って延びる筒状部６３が形成されている。***部６２は、バーナキャップ６の上面に鍋等から煮汁がこぼれ落ちたとき、煮汁の炎口９への侵入を可及的に抑止する。筒状部６３は、万一炎口９に煮汁が侵入したとき、煮汁を直下に案内し、筒状部６３の下縁で水切りする。このとき、図２に示すように、炎口９の直下には受け皿部材８が設けられているので、炎口９から落下した煮汁は受け皿部材８に受けられて溜まる。受け皿部材８は、バーナヘッド５から着脱自在とされている。よって受け皿部材８を取り外して洗浄等の作業が容易である。 As shown in FIGS. 3 and 4, the burner cap 6 is formed with a raised portion 62 that rises along the inner peripheral edge of the flame opening 9. Furthermore, as shown in FIG. 4, a cylindrical portion 63 extending downward from the entire inner peripheral edge of the flame opening 9 is formed. The raised portion 62 prevents the broth from entering the flame opening 9 as much as possible when the broth spills from the pan or the like on the upper surface of the burner cap 6. The cylindrical portion 63 guides the broth immediately below when the broth enters the flame opening 9, and drains it at the lower edge of the tubular portion 63. At this time, as shown in FIG. 2, since the saucer member 8 is provided directly below the flame opening 9, the broth dropped from the flame opening 9 is received by the saucer member 8 and collected. The tray member 8 is detachable from the burner head 5. Therefore, it is easy to perform operations such as cleaning by removing the tray member 8.
受け皿部材８は、バーナヘッド５の分布室７の上部壁５３の上面に載置される環状の底部８１と、底部８１の内周縁から立ち上がってバーナヘッド５の開放部７１の案内壁５４に密着する内周壁８２と、底部８１の外周縁から起立してバーナキャップ６の炎口９よりも外側位置に向って延びる外周壁８３（起立壁）とを備えている。 The tray member 8 is mounted on the upper surface of the upper wall 53 of the distribution chamber 7 of the burner head 5, and the guide plate 54 of the open portion 71 of the burner head 5 rises from the inner peripheral edge of the bottom portion 81. And an outer peripheral wall 83 (standing wall) that stands up from the outer peripheral edge of the bottom 81 and extends toward the outer side of the flame opening 9 of the burner cap 6.
受け皿部材８の外周壁８３は、バーナキャップ６の下面から垂下する筒状の閉塞壁６４に気密に当接し、混合ガスを確実に炎口９へ導く。 The outer peripheral wall 83 of the tray member 8 is in airtight contact with a cylindrical blocking wall 64 that hangs down from the lower surface of the burner cap 6, and reliably guides the mixed gas to the flame port 9.
また、図２に示すように、バーナキャップ６は、天板１のバーナ用開口１ａよりも大径に形成されている。これにより、バーナ用開口１ａはバーナキャップ６に覆われ、バーナ用開口１ａからコンロ内部への異物の侵入はバーナキャップ６によって阻止される。 As shown in FIG. 2, the burner cap 6 is formed with a larger diameter than the burner opening 1 a of the top plate 1. As a result, the burner opening 1 a is covered with the burner cap 6, and entry of foreign matter from the burner opening 1 a into the stove is blocked by the burner cap 6.
また、図３に示すように、バーナキャップ６には、外周縁における径方向に対向する位置に一対の凹部６５が形成されている。この凹部６５は、図１に示すように、五徳爪２１の基部から内方に延設した延設部２２が係合する本発明の係合部として機能する。 As shown in FIG. 3, the burner cap 6 is formed with a pair of concave portions 65 at positions on the outer peripheral edge facing each other in the radial direction. As shown in FIG. 1, the concave portion 65 functions as an engaging portion of the present invention that engages with the extending portion 22 that extends inwardly from the base portion of the virgin claw 21.
これによれば、バーナキャップ６の炎口９と五徳爪２１との位置関係が常に同じになるため、例えば、バーナキャップ６の炎口９と五徳爪２１との位置ずれ等が原因となる五徳爪２１の炙りを防止することができる。 According to this, since the positional relationship between the flame outlet 9 of the burner cap 6 and the five virtue claws 21 is always the same, for example, the five virtues caused by the positional deviation between the flame mouth 9 of the burner cap 6 and the five virtue claws 21 or the like. It is possible to prevent the nail 21 from being beaten.
なお、本実施形態においては、バーナキャップ６の凹部６５に五徳爪２１の延設部２２を係合させる構成としたが、これに限るものではない。例えば、図示しないが、五徳の一部に内側に延出させた延出部を設けてバーナキャップ６の凹部６５に係合させてもよい。 In the present embodiment, the extended portion 22 of the five virtue claws 21 is engaged with the recessed portion 65 of the burner cap 6, but the present invention is not limited to this. For example, although not shown, an extension portion extended inward may be provided in a part of the virtues, and the recess 65 of the burner cap 6 may be engaged.
