Abstract

PROBLEM TO BE SOLVED: To prevent degradation in pot heating efficiency in a stove burner provided with an annular wall having a burner port on an outer circumference of a lower surface of a burner cap and an annular bank part formed at a position radially inward of the annular wall, and designed to prevent boiling-over water or soup from entering inward of the bank part.SOLUTION: A guide wall 32 is formed on a lower surface of a burner cap 3 to be suspended at a position radially inward of a bank part 26, and a guide surface 33 inclined upward in a radially outward direction is provided on a lower end of the guide wall 32 to be inserted into a space radially inward of the bank part 26 to form an air-mixture inlet passage between the bank part 26 and the guide surface 33. The guide surface 33 is formed such that an extension 33a of a generatrix of the guide surface 33 passes through a height equal to or smaller than a height of an upper edge 4a of an inner end portion of a burner port 4 opening in an inner circumferential surface of the annular wall 31.

Description

本発明は、バーナボディと、バーナボディ上に載置されるバーナキャップとを備え、バーナボディの上面外周部又はバーナキャップの下面外周部に、バーナボディとバーナキャップとの間に上下方向の隙間を確保する環状壁が設けられ、この環状壁に多数の炎口が形成されたコンロバーナに関する。   The present invention includes a burner body and a burner cap mounted on the burner body, and a vertical gap is provided between the burner body and the burner cap on the upper surface outer periphery of the burner body or the lower surface outer periphery of the burner cap. The present invention relates to a stove burner in which an annular wall is provided to secure a large number of holes, and a plurality of flame openings are formed in the annular wall.

従来、この種のコンロバーナとして、バーナボディの上面に、環状壁よりも径方向内方位置で上方に突出する環状の堤部とを形成して、堤部よりも径方向内方の空間を介して供給される混合気が炎口から噴出するように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、炎口から煮こぼれ汁が流入しても、煮こぼれ汁は堤部で堰き止められて、堤部より内方に煮こぼれ汁が侵入することを防止できる。   Conventionally, as this kind of stove burner, an annular bank portion protruding upward at a radially inward position from the annular wall is formed on the upper surface of the burner body, and a space radially inward from the bank portion is formed. There is known a system in which an air-fuel mixture supplied through a nozzle is ejected from a flame outlet (see, for example, Patent Document 1). In this case, even if the boiled spilled juice flows from the flame outlet, the boiled spilled juice is blocked by the bank and can be prevented from invading from the bank.

また、鍋の加熱効率を向上させるには、炎口から噴出する混合気の燃焼で生成される燃焼ガスが鍋底の径方向内方部分に当たるようにする必要がある。そこで、従来、炎口の上縁を径方向外方に向けて上方に傾斜させ、混合気が上方への方向成分を持って炎口から噴出するようにしている。   Further, in order to improve the heating efficiency of the pan, it is necessary that the combustion gas generated by the combustion of the air-fuel mixture ejected from the flame outlet hits the radially inner portion of the pan bottom. Therefore, conventionally, the upper edge of the flame mouth is inclined upward in the radial direction so that the air-fuel mixture is ejected from the flame mouth with an upward direction component.

然し、バーナボディの上面外周部に上記の如く堤部を形成すると、混合気が堤部の内方空間を上向きに流れてバーナキャップの下面に当たり、混合気の一部が下向きの方向成分を持って炎口に流入するようになる。その結果、炎口の上縁を径方向外方に向けて上方に傾斜させても、炎口からの混合気の噴出方向が水平になりやすく、鍋の加熱効率が悪くなってしまう。   However, when a bank is formed on the outer periphery of the upper surface of the burner body as described above, the mixture flows upward in the inner space of the bank and hits the lower surface of the burner cap, and a part of the mixture has a downward direction component. Will flow into the flame outlet. As a result, even if the upper edge of the flame outlet is inclined upward in the radial direction, the direction in which the air-fuel mixture is ejected from the flame mouth tends to be horizontal, and the heating efficiency of the pan becomes poor.

特開平１０−３１８５０６号公報JP 10-318506 A

本発明は、以上の点に鑑み、バーナボディの上面に堤部を形成するにも拘らず鍋の加熱効率の悪化を生じないようにしたコンロ用バーナを提供することをその課題としている。   This invention makes it the subject to provide the burner for stoves which did not produce the deterioration of the heating efficiency of a pan, although the embankment part was formed in the upper surface of a burner body in view of the above point.

上記課題を解決するために、本発明は、バーナボディと、バーナボディ上に載置されるバーナキャップとを備え、バーナボディの上面外周部又はバーナキャップの下面外周部に、バーナボディとバーナキャップとの間に上下方向の隙間を確保する環状壁が設けられ、バーナボディの上面に、環状壁よりも径方向内方位置で上方に突出する環状の堤部とが形成され、環状壁に、堤部よりも径方向内方の空間を介して供給される混合気が噴出する多数の炎口が形成されたコンロバーナであって、炎口の上縁が径方向外方に向けて上方に傾斜しているものにおいて、バーナキャップの下面に、堤部よりも径方向内方位置で垂下するガイド壁が形成され、ガイド壁の下端に、堤部よりも径方向内方の空間に挿入されて堤部との間に混合気の流入通路を画成する、径方向外方に向けて上方に傾斜したガイド面が設けられ、ガイド面は、当該ガイド面の母線の延長線が環状壁の内周面に開口する炎口の内端部の上縁以下の高さを通るように形成されることを特徴とする。   In order to solve the above-described problems, the present invention includes a burner body and a burner cap placed on the burner body, and the burner body and the burner cap are disposed on the upper surface outer periphery of the burner body or the lower surface outer periphery of the burner cap. An annular wall that secures a gap in the vertical direction is provided between and an upper surface of the burner body is formed with an annular bank portion protruding upward at a radially inward position from the annular wall. A stove burner in which a large number of flame outlets are formed through which air-fuel mixture supplied through a space radially inward from the bank is ejected, with the upper edge of the flame outlet facing upward in the radial direction In the inclined one, a guide wall is formed on the lower surface of the burner cap so as to hang radially inward from the bank, and is inserted into a space radially inward from the bank at the lower end of the guide wall. The air-fuel mixture inflow passage is A guide surface inclined upward in the radial direction is formed, and the guide surface is formed on the inner end of the flame opening where the extension of the generatrix of the guide surface opens on the inner peripheral surface of the annular wall. It is formed so as to pass through a height below the edge.

本発明によれば、流入通路からガイド面の傾斜に沿う方向成分を持って混合気が環状壁側に流れる。そして、ガイド面の母線の延長線が環状壁の内周面に開口する炎口の内端部の上縁以下の高さを通るため、ガイド面の傾斜に沿う方向成分を持つ混合気は、環状壁よりも径方向内方でバーナキャップの下面に当たったり、炎口の内端部上縁より上方の環状壁の内周面に当たったりすることなく、炎口に流入する。従って、堤部が存在しても、混合気は確実に上方への方向成分を持って炎口から噴出して燃焼し、鍋の加熱効率が悪化することはない。   According to the present invention, the air-fuel mixture flows from the inflow passage to the annular wall side with a directional component along the inclination of the guide surface. And since the extension of the generatrix of the guide surface passes through the height below the upper edge of the inner end of the flame opening that opens to the inner peripheral surface of the annular wall, the air-fuel mixture having a directional component along the inclination of the guide surface is It flows into the flame mouth without hitting the lower surface of the burner cap radially inward of the annular wall or hitting the inner peripheral surface of the annular wall above the upper edge of the inner end of the flame mouth. Therefore, even if the bank portion is present, the air-fuel mixture surely has an upward direction component and is burned out from the flame outlet, so that the heating efficiency of the pan does not deteriorate.

図１を参照して、本発明の実施形態のコンロバーナ１は、図示省略したコンロ天板のバーナ用開口に挿通されるバーナボディ２と、バーナボディ２上のバーナキャップ３とを備えている。   Referring to FIG. 1, a stove burner 1 according to an embodiment of the present invention includes a burner body 2 inserted into a burner opening of a stove top plate (not shown), and a burner cap 3 on the burner body 2. .

バーナボディ２は、図２に示す如く、外側の筒体２１と中間の筒体２２と内側の筒体２３との内外３重の筒体を有する主体部と、内周に中間筒体２２に嵌合する筒部２４ａを垂設した環状のアダプタ２４とで構成されている。アダプタ２４の下面外周部には、外側筒体２１の上端部に着座する環状壁２４ｂが垂設されており、この環状壁２４ｂに多数の副炎口４´を形成している。   As shown in FIG. 2, the burner body 2 includes a main body having an inner and outer triple cylinders of an outer cylinder 21, an intermediate cylinder 22, and an inner cylinder 23, and an intermediate cylinder 22 on the inner periphery. It is comprised with the cyclic | annular adapter 24 which suspended the cylinder part 24a to fit. An annular wall 24b seated on the upper end portion of the outer cylinder 21 is suspended from the outer peripheral portion of the lower surface of the adapter 24, and a plurality of auxiliary flame ports 4 'are formed in the annular wall 24b.

バーナキャップ３は、環状であって、下面外周部に環状壁３１が垂設されている。この環状壁３１は、バーナボディ２の上面外周部、即ち、アダプタ２４の上面外周部に形成した座面２５に着座し、アダプタ２４とバーナキャップ３との間に上下方向の隙間を確保される。そして、環状壁３１に、後述する堤部２６よりも径方向内方の空間を介して供給される混合気が噴出する多数の炎口４を形成している。   The burner cap 3 is annular, and an annular wall 31 is suspended from the outer periphery of the lower surface. The annular wall 31 is seated on the outer peripheral portion of the upper surface of the burner body 2, that is, the seat surface 25 formed on the outer peripheral portion of the upper surface of the adapter 24, and a vertical gap is secured between the adapter 24 and the burner cap 3. . A large number of flame ports 4 are formed in the annular wall 31 from which the air-fuel mixture supplied through a space radially inward from the bank 26 described later is ejected.

また、アダプタ２４の上面には、環状壁３１よりも径方向内方位置、即ち、座面２５よりも径方向内方位置で上方に突出する環状の堤部２６が形成されている。そのため、炎口４から煮こぼれ汁が流入しても、煮こぼれ汁は堤部２６で堰き止められて、堤部２６より内方に煮こぼれ汁が侵入することを防止できる。   Further, an annular bank portion 26 is formed on the upper surface of the adapter 24 so as to protrude upward at a radially inward position from the annular wall 31, that is, at a radially inward position from the seat surface 25. Therefore, even if the boiled spilled juice flows from the flaming port 4, the boiled spilled juice is blocked by the bank portion 26, and it is possible to prevent the spilled juice from entering the inside of the bank portion 26.

バーナ１は、更に、バーナボディ２の中間筒体２２と内側筒体２３との間の空間に連通する第１混合管５１と、バーナボディ２の外側筒体２１と中間筒体２２との間の空間に連通する第２混合管５２とを備える。そして、第１混合管５１から供給される混合気が中間筒体２２と内側筒体２３との間の空間を経由して炎口４から噴出し、第２混合管５２から供給される混合気が外側筒体２１と中間筒体２２との間の空間を経由して副炎口４´から噴出するようにいている。 Burner 1 further includes a first mixing tube 5 1 which communicates with the space between the intermediate cylinder 22 and the inner cylinder 23 of the burner body 2, the outer cylinder 21 and the intermediate cylinder 22 of the burner body 2 a second mixing tube 5 2 communicating with the space between. Then, the mixture supplied is ejected from the burner port 4 via the space between the intermediate cylinder 22 and the inner cylinder 23, supplied from the second mixing tube 5 2 from the first mixing tube 5 1 The air-fuel mixture is ejected from the auxiliary flame outlet 4 ′ via the space between the outer cylinder 21 and the intermediate cylinder 22.

図１を参照して、第１混合管５１には、共通ガス供給路６から分岐した第１ガス供給路６１を介して燃料ガスが供給され、第２混合管５２には、共通ガス供給路６から分岐した第２ガス供給路６２を介して燃料ガスが供給される。共通ガス供給路６には、元電磁弁６１と、ガス流量調節弁６２とが介設され、また、第１ガス供給路６１には、電磁弁６３が介設されている。そして、電磁弁６３の閉弁と開弁とにより、副炎口４´のみから混合気を噴出させて燃焼させる状態と、炎口４からも混合気を噴出させて燃焼させる状態とに切換自在としている。 Referring to FIG. 1, the first mixing tube 5 1, is supplied the fuel gas through the first gas supply passage 61 branched from the common gas supply passage 6, the second mixing tube 5 2, common fuel gas is supplied through the second gas supply passage 6 2 branched from the gas supply channel 6. The common gas supply channel 6, a source electromagnetic valve 61 is interposed and a gas flow control valve 62, also, the first gas supply passage 61, the solenoid valve 63 is interposed. Then, by closing and opening the solenoid valve 63, the state can be switched between a state in which the air-fuel mixture is jetted and burned only from the sub-flame port 4 'and a state in which the air-fuel mixture is also jetted from the flame port 4 and burned. It is said.

尚、第１混合管５１には、給気ファン７から一次空気が強制的に供給されるようにしている。また、バーナ１の周方向一箇所には点火プラグ８が設けられている。 Note that the first mixing tube 5 1, so that primary air is forcibly supplied from the air supply fan 7. A spark plug 8 is provided at one place in the circumferential direction of the burner 1.

ところで、鍋の加熱効率を向上させるには、炎口４から噴出する混合気の燃焼で生成される燃焼ガスが鍋底の径方向内方部分に当たるようにする必要がある。そこで、炎口４の上縁を径方向外方に向けて上方に傾斜させ、混合気が上方への方向成分を持って炎口４から噴出するようにしている。また、本実施形態では、混合気に上方への方向成分を与えやすくするため、炎口４の下縁となる座面２５も径方向外方に向けて上方に傾斜させている。   By the way, in order to improve the heating efficiency of the pan, it is necessary that the combustion gas generated by the combustion of the air-fuel mixture ejected from the flame port 4 strikes the radially inner portion of the pan bottom. Therefore, the upper edge of the flame opening 4 is inclined upward in the radial direction so that the air-fuel mixture is ejected from the flame opening 4 with an upward direction component. Further, in this embodiment, in order to easily give an upward direction component to the air-fuel mixture, the seat surface 25 serving as the lower edge of the flame outlet 4 is also inclined upward in the radial direction.

但し、上記の如く堤部２６を形成した場合は、混合気が堤部２６の内方空間を上向きに流れてバーナキャップ３の下面に当たり、混合気の一部が下向きの方向成分を持って炎口４に流入するようになって、炎口４の上縁を径方向外方に向けて上方に傾斜させても、炎口４からの混合気の噴出方向が水平になりやすくなる。   However, when the bank portion 26 is formed as described above, the air-fuel mixture flows upward in the inner space of the bank portion 26 and hits the lower surface of the burner cap 3, and a part of the air-fuel mixture has a downward direction component and flame. Even when the upper edge of the flame outlet 4 is inclined upward in the radial direction by flowing into the mouth 4, the jet direction of the air-fuel mixture from the flame mouth 4 tends to become horizontal.

そこで、本実施形態では、バーナキャップ３の下面に、堤部２６よりも径方向内方位置で垂下するガイド壁３２を形成し、ガイド壁３２の下端に、堤部２６よりも径方向内方の空間に挿入されて堤部２６との間に混合気の流入通路を画成する、径方向外方に向けて上方に傾斜したガイド面３３を設けている。そして、図３に明示する如く、ガイド面３３を、当該ガイド面３３の母線の延長線３３ａが環状壁３１の内周面に開口する炎口４の内端部の上縁４ａ以下の高さを通るように形成している。   Therefore, in the present embodiment, a guide wall 32 that hangs in a radially inward position from the bank portion 26 is formed on the lower surface of the burner cap 3, and a radially inner side than the bank portion 26 is formed at the lower end of the guide wall 32. A guide surface 33 which is inserted into the space and defines an air-inflow passage for the air-fuel mixture with the bank 26 and which is inclined upward in the radial direction is provided. Then, as clearly shown in FIG. 3, the guide surface 33 has a height not more than the upper edge 4 a of the inner end portion of the flame outlet 4 where the extension line 33 a of the generatrix of the guide surface 33 opens on the inner peripheral surface of the annular wall 31. It is formed to pass through.

これによれば、流入通路からガイド面３３の傾斜に沿う方向成分を持って混合気が環状壁３１側に流れる。そして、ガイド面３３の母線の延長線３３ａが炎口４の内端部上縁４ａ以下の高さを通るため、ガイド面３３の傾斜に沿う方向成分を持つ混合気は、環状壁３１よりも径方向内方でバーナキャップ３の下面に当たったり、炎口４の内端部上縁４ａより上方の環状壁３１の内周面に当たったりすることなく、炎口４に流入する。従って、堤部２６が存在しても、混合気は確実に上方への方向成分を持って炎口４から噴出して燃焼し、鍋の加熱効率が悪化することはない。   According to this, the air-fuel mixture flows from the inflow passage toward the annular wall 31 with a directional component along the inclination of the guide surface 33. Since the extension line 33a of the bus bar of the guide surface 33 passes through the height below the upper edge 4a of the inner end portion of the flame opening 4, the air-fuel mixture having a directional component along the inclination of the guide surface 33 is more than the annular wall 31. It flows into the flame mouth 4 without hitting the lower surface of the burner cap 3 in the radial direction or hitting the inner peripheral surface of the annular wall 31 above the upper edge 4a of the inner end of the flame mouth 4. Therefore, even if the bank portion 26 exists, the air-fuel mixture surely has an upward directional component and is jetted from the flame outlet 4 and burned, and the heating efficiency of the pan does not deteriorate.

尚、ガイド壁３２は、バーナボディ２の内側筒体２３に外嵌するように筒状に形成されている。また、座面２５と堤部２６との間に溜まった煮こぼれ汁が堤部２６を越えて侵入することがないように、堤部２６の上端は、座面２５の上端より高くなっている。   The guide wall 32 is formed in a cylindrical shape so as to be fitted on the inner cylindrical body 23 of the burner body 2. In addition, the upper end of the bank portion 26 is higher than the upper end of the seat surface 25 so that the simmered juice collected between the seat surface 25 and the bank portion 26 does not enter beyond the bank portion 26. .

ところで、上記実施形態では、環状壁３１の内周面に段部は形成されていないが、図４に示す実施形態の如く、環状壁３１の内周面の炎口４の内端部上縁４ａ以上の高さの上端部分に、径方向内方に張り出し、径方向内端部が堤部２６よりも径方向外方に位置する段部３１ａを形成してもよい。これによれば、炎口４の上縁を伝って流入する煮こぼれ汁を堤部２６よりも径方向外方位置で段部３１ａの径方向内端部から落下させて、堤部２６よりも内方への煮こぼれ汁の落下を防止できる。   By the way, in the said embodiment, although the step part is not formed in the internal peripheral surface of the annular wall 31, like the embodiment shown in FIG. 4, the inner edge part upper edge of the flame mouth 4 of the internal peripheral surface of the annular wall 31 is shown. A stepped portion 31a may be formed on the upper end portion having a height of 4a or more and projecting inward in the radial direction, with the radially inner end positioned radially outward from the bank portion 26. According to this, the boiled sap that flows along the upper edge of the flame outlet 4 is dropped from the radially inner end of the step portion 31 a at a radially outward position from the bank portion 26, and more than the bank portion 26. The falling of the spilled juice inward can be prevented.

この場合も、上記実施形態と同様に、ガイド面３３の母線の延長線３３ａが炎口４の内端部上縁４ａ以下の高さを通るようにガイド面３３を形成することで、ガイド面３３の傾斜に沿う方向成分を持つ混合気は、段部３１ａに当たることなく、炎口４に流入する。   In this case as well, the guide surface 33 is formed so that the extension line 33a of the bus bar of the guide surface 33 passes through the height of the inner edge portion upper edge 4a or less of the flame mouth 4 in the same manner as in the above embodiment. The air-fuel mixture having a directional component along the inclination of 33 flows into the flame outlet 4 without hitting the step portion 31a.

以上、本発明の実施形態について図面を参照して説明したが、本発明はこれに限定されない。例えば、上記実施形態では、座面２５を径方向外方に向かって上方に傾斜する傾斜面に形成しているが、座面２５の周方向一部、例えば、一部の炎口４に合致する部分に、下方への窪みを形成し、座面２５と堤部２６との間に溜まった煮こぼれ汁が窪みを介して外方に排出されるようにしてもよい。   As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above-described embodiment, the seat surface 25 is formed as an inclined surface that is inclined upward in the radial direction. However, the seat surface 25 matches a part of the seat surface 25 in the circumferential direction, for example, a part of the flame ports 4. It is also possible to form a depression in the lower part so that the boiled juice accumulated between the seating surface 25 and the bank 26 is discharged outward through the depression.

また、上記実施形態では、バーナキャップ３の下面外周部に環状壁３１を垂設しているが、バーナボディ２を構成するアダプタ２４の上面外周部に環状壁を立設して、この環状壁に炎口４を形成することも可能である。また、上記実施形態のコンロバーナ１は、アダプタ２４付きで炎口４の下方に副炎口４´を有するものであるが、アダプタ２４を省略した副炎口４´を有しないコンロバーナにも同様に本発明を適用できる。   In the above embodiment, the annular wall 31 is suspended from the outer peripheral portion of the lower surface of the burner cap 3. However, the annular wall is provided upright on the outer peripheral portion of the upper surface of the adapter 24 constituting the burner body 2. It is also possible to form the flame opening 4. In addition, the stove burner 1 of the above embodiment has the adapter 24 and has the auxiliary flame outlet 4 ′ below the flame outlet 4, but also in the stove burner without the auxiliary flame outlet 4 ′ in which the adapter 24 is omitted. Similarly, the present invention can be applied.
