A cylindrical wall 51 seated on the upper surface of the burner body is vertically provided on the outer periphery of a lower surface of the burner cap, and a plurality of flame holes communicating with the space is formed on the cylindrical wall at an interval in the circumferential direction. On the inner peripheral edge of the burner cap, a cylindrical part 55 extending downward to be fitted to the inner peripheral edge of the burner body is vertically provided, and on the outer surface of the cylindrical part facing the space, a plurality of projections 57 extending vertically at an interval in the circumferential direction is provided.

Description

本発明は、ガスコンロに設けられるコンロ用バーナに関し、特に、バーナキャップがアルミニウム製であるものに関する。   The present invention relates to a stove burner provided in a gas stove, and particularly relates to a burner cap made of aluminum.
この種のコンロ用バーナは例えば特許文献1で知られている。このものは、燃料ガスと一次空気との混合気が供給される空間を有する環状のバーナボディと、このバーナボディ上に載置される環状のバーナキャップとを備える。バーナキャップの下面外周部には、バーナボディの上面に着座する筒壁部が垂設され、この筒壁部には、周方向の間隔を存して上記空間に通じる多数の炎孔が形成されている。バーナキャップとしてアルミニウムの鋳造品を用いる場合、その融点が低いため、バーナキャップが融点以上に過熱されて溶けないようにする必要がある。   This type of stove burner is known from Patent Document 1, for example. This includes an annular burner body having a space to which a mixture of fuel gas and primary air is supplied, and an annular burner cap placed on the burner body. A cylindrical wall portion seated on the upper surface of the burner body is suspended from the outer peripheral portion of the lower surface of the burner cap, and a plurality of flame holes are formed in the cylindrical wall portion so as to communicate with the space with a circumferential interval. ing. When an aluminum casting is used as the burner cap, its melting point is low, so it is necessary to prevent the burner cap from being melted by being overheated above the melting point.
上記従来例のものでは、バーナキャップの内周縁に、下方にのびてバーナボディの内周縁に嵌合する筒部が垂設されると共に、バーナキャップの上面に筒部上端から径方向外方へとのびる突条を周方向に間隔を存して多数設けている。これにより、バーナ燃焼時、バーナキャップの筒部内からバーナキャップ上を通って炎孔に供給される二次空気との接触面積が突条を設けることで増加し、バーナキャップが融点以上に過熱されないようになる。然し、バーナキャップ上面に突条を設けることでバーナキャップ上面が凹凸形状になっていると、調理時に生じた煮こぼれでバーナキャップ上に煮汁が零れ落ちたとき、煮汁を払拭することが難しく、バーナキャップを簡単にお手入れできないという問題がある。   In the above-mentioned conventional example, a cylindrical portion that extends downward and fits to the inner peripheral edge of the burner body is suspended from the inner peripheral edge of the burner cap, and radially outward from the upper end of the cylindrical portion on the upper surface of the burner cap. A number of protruding ridges are provided at intervals in the circumferential direction. Thereby, at the time of burner combustion, the contact area with the secondary air supplied to the flame hole through the burner cap from inside the cylinder portion of the burner cap is increased by providing a protrusion, and the burner cap is not overheated to the melting point or more. It becomes like this. However, if the upper surface of the burner cap is uneven by providing protrusions on the upper surface of the burner cap, it is difficult to wipe off the broth when the broth spills on the burner cap due to spilling during cooking, There is a problem that the burner cap cannot be easily cared for.
なお、上記従来例のものでは、バーナキャップの上方に円盤状のバーナカバーを上下方向の間隔を存して設け、バーナカバーで煮汁を受けることができるようにしているが、バーナカバーの上面から漏れ出した煮汁がバーナカバーの裏面を伝ってバーナキャップ上に落下するため、上記の問題を生ずる。   In the above conventional example, a disc-shaped burner cover is provided above the burner cap with a space in the vertical direction so that the burner cover can receive the broth, but from the upper surface of the burner cover Since the leaked broth falls on the burner cap along the back surface of the burner cover, the above problem occurs.
特開2011−2102号公報JP 2011-2102 A
本発明は、以上の点に鑑み、バーナ燃焼時にアルミニウム製のバーナキャップが融点以上に過熱されることを防止する機能を有しながら、バーナキャップを簡単にお手入れできる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するものである。   In view of the above, the present invention provides a stove burner that can easily clean a burner cap while having a function of preventing the aluminum burner cap from being overheated to the melting point or more during burner combustion. The issue is to provide.
上記課題を解決するために、本発明のコンロ用バーナは、燃料ガスと一次空気との混合気が供給される空間を有する環状のバーナボディと、このバーナボディ上に載置される環状のバーナキャップとを備え、バーナキャップの下面外周部にバーナボディの上面に着座する筒壁部が垂設されて、この筒壁部に周方向の間隔を存して上記空間に通じる多数の炎孔が形成され、バーナキャップの内周縁に、下方にのびてバーナボディの内周縁に嵌合する筒部が垂設され、バーナキャップがアルミニウム製であり、バーナボディ内の空間に面する筒部の外表面に、周方向に間隔を存して上下方向にのびる複数の突条が設けられることを特徴とする。   In order to solve the above-described problems, a stove burner according to the present invention includes an annular burner body having a space to which a mixture of fuel gas and primary air is supplied, and an annular burner placed on the burner body. And a cylindrical wall portion seated on the upper surface of the burner body is suspended from the outer peripheral portion of the lower surface of the burner cap, and a plurality of flame holes communicating with the space are provided in the cylindrical wall portion at intervals in the circumferential direction. A cylindrical portion is formed on the inner peripheral edge of the burner cap so as to extend downward and fit to the inner peripheral edge of the burner body, and the burner cap is made of aluminum, and is outside the cylindrical portion facing the space in the burner body. The surface is provided with a plurality of protrusions extending in the up-down direction at intervals in the circumferential direction.
本発明によれば、バーナ燃焼時、特に、バーナキャップの炎孔の近傍が加熱されるが、炎孔に供給される混合気と筒部との接触面積が突条を設けることで増加して筒部が効率よく冷却され、この筒部へと熱引けすることで、バーナキャップが融点以上に過熱されることはない。このように本発明では、混合気でバーナキャップを冷却して過熱防止する構成を採用したため、バーナキャップの上面に殊更突条を設ける必要がない。このため、バーナキャップ上に零れ落ちた煮汁を簡単に払拭することができ、バーナキャップのお手入れは簡単である。   According to the present invention, during burner combustion, in particular, the vicinity of the flame hole of the burner cap is heated, but the contact area between the air-fuel mixture supplied to the flame hole and the cylinder part is increased by providing the protrusion. The cylinder part is efficiently cooled, and heat is drawn to the cylinder part, so that the burner cap is not overheated to the melting point or higher. As described above, in the present invention, since the configuration in which the burner cap is cooled with the air-fuel mixture to prevent overheating is employed, it is not necessary to provide a further protrusion on the upper surface of the burner cap. For this reason, it is possible to easily wipe off the spilled broth on the burner cap, and the burner cap is easy to clean.
本発明においては、混合気との接触面積を可及的に増加させるため、前記突条は、前記筒部の上端から前記バーナボディの内周縁に嵌合する筒部の部分の直上までのびるように形成されることが好ましい。   In the present invention, in order to increase the contact area with the air-fuel mixture as much as possible, the ridge extends from the upper end of the cylindrical portion to a position directly above the portion of the cylindrical portion fitted to the inner peripheral edge of the burner body. It is preferable to be formed.
また、本発明においては、前記バーナキャップ下面の前記筒部と前記筒壁部との間の部分に、前記炎孔の上端より上方に窪んだ凹部を有することが好ましい。これによれば、筒部と筒壁部との間で凹部に回り込むようにして混合気が流れ、バーナキャップに対する混合気の接触面積が増加してバーナキャップの過熱を一層確実に防止することができる。   Moreover, in this invention, it is preferable to have a recessed part dented above the upper end of the said flame hole in the part between the said cylinder part and the said cylinder wall part of the said burner cap lower surface. According to this, the air-fuel mixture flows so as to wrap around the concave portion between the tube portion and the tube wall portion, and the contact area of the air-fuel mixture with respect to the burner cap increases, thereby preventing the burner cap from overheating more reliably. it can.

以下、図面を参照して本発明の実施形態のコンロ用バーナを説明する。図1を参照して、1は、ガスコンロのコンロ本体を示す。コンロ本体1の開口した上面には天板2が載置されている。天板2にはバーナ用開口2aが開設され、上記バーナ用開口2aを通して上方に突出するようにコンロ用バーナBuが設けられている。なお、特に図示して説明しないが、バーナ用開口2aの周囲には五徳が配置され、この五徳に鍋等の調理容器を設置して加熱調理が行われる。   Hereinafter, a stove burner according to an embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 1, reference numeral 1 denotes a stove body of a gas stove. A top plate 2 is placed on the open upper surface of the stove body 1. The top plate 2 is provided with a burner opening 2a, and a stove burner Bu is provided so as to protrude upward through the burner opening 2a. Although not specifically illustrated and described, five virtues are arranged around the burner opening 2a, and cooking is performed by installing a cooking container such as a pot in the five virtues.
図2、図3も参照して、コンロ用バーナBuは、コンロ本体1内に設置される混合管3と、混合管3の下流端部に一体成形され、天板2のバーナ用開口2aに挿設される環状のバーナボディ4と、バーナボディ4上に着脱自在に載置される環状のバーナキャップ5とを備える。混合管3の上流端には、図示省略のガスノズルが臨んでおり、このガスノズルにより混合管3内に燃料ガスを噴出すると、燃料ガスと混合管3の上流端から吸込まれる一次空気との混合気が混合管3内で生成される。   2 and 3, the stove burner Bu is integrally formed with the mixing tube 3 installed in the stove body 1 and the downstream end of the mixing tube 3, and is formed in the burner opening 2 a of the top plate 2. An annular burner body 4 that is inserted and an annular burner cap 5 that is detachably mounted on the burner body 4 are provided. A gas nozzle (not shown) faces the upstream end of the mixing tube 3. When the fuel gas is ejected into the mixing tube 3 by the gas nozzle, the fuel gas and the primary air sucked from the upstream end of the mixing tube 3 are mixed. Gas is generated in the mixing tube 3.
バーナボディ4は、外筒部41と内筒部42とを備え、混合管3から混合気が外筒部41と内筒部42との間の空間43へと供給される。また、外筒部41の上端には、径方向内方でかつ斜め下方に向けて屈曲させたフランジ部41aが形成され、内筒部42の上端内周縁部には、下方に屈曲するシール部42aが形成され、このシール部42aに、後述のバーナキャップ5の筒部55が嵌合するようになっている。   The burner body 4 includes an outer cylinder part 41 and an inner cylinder part 42, and the air-fuel mixture is supplied from the mixing tube 3 to a space 43 between the outer cylinder part 41 and the inner cylinder part 42. Further, a flange portion 41a is formed at the upper end of the outer cylinder portion 41 and is bent radially inward and obliquely downward, and a seal portion that is bent downward is provided at the upper inner peripheral edge of the inner cylinder portion 42. 42a is formed, and a cylindrical portion 55 of a burner cap 5 described later is fitted into the seal portion 42a.
アルミニウムの鋳造品であるバーナキャップ5の上面は平坦に形成され、その下面の外周部には、バーナボディ4のフランジ部41a上面に着座する筒壁部51が垂設されている。筒壁部51には、周方向の間隔を存して、上下方向寸法が比較的大きい炎孔52aと、上下方向寸法が比較的小さい炎孔52bとが交互に形成されている。ここで、バーナ用開口2aの周囲に配置される五徳は、例えば6個の五徳爪を備え、これら五徳爪に火炎が接触すると、不完全燃焼する虞がある。そこで、6個の五徳爪のうち4個の五徳爪と同一方位に位置する筒壁部51の部分51aは、その他の部分と比較して、径方向内側に向けて後述の筒部55の近傍まで延出され、この部分51aには、上下方向寸法が比較的小さくて幅広の炎孔52cが形成されている。   The upper surface of the burner cap 5, which is a cast product of aluminum, is formed flat, and a cylindrical wall portion 51 that sits on the upper surface of the flange portion 41 a of the burner body 4 is suspended from the outer peripheral portion of the lower surface. In the cylindrical wall portion 51, flame holes 52 a having a relatively large vertical dimension and flame holes 52 b having a relatively small vertical dimension are alternately formed with a circumferential interval. Here, the five virtues arranged around the burner opening 2a include, for example, six virtue claws, and there is a risk of incomplete combustion when a flame contacts the five virtue claws. Therefore, the portion 51a of the cylindrical wall portion 51 that is located in the same orientation as the four of the five virtue claws out of the six virtue claws is closer to the later-described cylindrical portion 55 toward the radially inner side than the other portions. The portion 51a is formed with a wide flame hole 52c having a relatively small vertical dimension.
また、筒壁部51には、6個の五徳爪のうち1個の五徳爪と同一方位に位置させて、点火電極6に対向するターゲット53が径方向外側に突設されていると共に、バーナキャップ5の上面には、ターゲット53を覆うように舌片状のカバー部材54が突設されている。この場合、ターゲット53が形成される筒壁部51の部分51bもまた、その他の部分と比較して、径方向内側に向けて後述の筒部の近傍まで延出され、この部分51bには、上下方向寸法が比較的小さくて幅広の炎孔52dが形成されている。   In addition, a target 53 facing the ignition electrode 6 is provided on the cylindrical wall portion 51 so as to be located in the same direction as one of the five virgin claws out of the six virgin claws. A tongue-like cover member 54 projects from the upper surface of the cap 5 so as to cover the target 53. In this case, the portion 51b of the cylindrical wall portion 51 where the target 53 is formed also extends radially inward to the vicinity of a cylindrical portion described later, and this portion 51b includes: A wide flame hole 52d having a relatively small vertical dimension is formed.
バーナキャップ5の内周縁部には、バーナボディ4のシール部42aに内嵌する筒部55が垂設され、筒部55内の空間には、その内部を通って上方に突出するように鍋底センサ7が配置されるようになっている。また、筒壁部51の部分51bから180°ずれた、6個の五徳爪のうち1個の五徳爪と同一方位に位置する筒部55の外表面には、下方に向けてのびる係合突起56が設けられ、コンロ用バーナBuの組付時、係合突起56がバーナボディ4のフランジ部41aに形成した切欠き部41bに係合することで位相決めされるようにしている。   At the inner peripheral edge of the burner cap 5, a cylinder part 55 that is fitted into the seal part 42 a of the burner body 4 is suspended, and the space in the cylinder part 55 protrudes upward through the inside thereof. A sensor 7 is arranged. Further, an engaging projection extending downward is formed on the outer surface of the cylindrical portion 55 located in the same orientation as one of the five virtue claws out of the six virtue claws, which is shifted from the portion 51b of the tubular wall portion 51 by 180 °. 56 is provided, and when the stove burner Bu is assembled, the engaging projection 56 is phased by engaging with the notch 41b formed in the flange 41a of the burner body 4.
バーナボディ4内の空間43に面する筒部55の外表面には、周方向に間隔を存して上下方向にのびる複数の突条57が設けられている。各突条57は、五徳爪と同一方位に位置する筒壁部51の部分51a、51bに対向する領域と係合突起56を設けた箇所とを避けた筒部55の外表面に所定間隔で夫々設けられ、筒部55の上端からバーナボディ4のシール部42aに内嵌する筒部55の部分の直上まで上下方向に真直にのびるようにしている。また、各突条57の上端部57aは、バーナキャップ5の下面に跨るように設けられている。更に、バーナキャップ5下面の筒部55と筒壁部51との間の部分には、上下方向寸法が比較的大きい炎孔52aの上端520より上方に窪んだ凹部50を有する。   On the outer surface of the cylindrical portion 55 facing the space 43 in the burner body 4, there are provided a plurality of protrusions 57 extending in the vertical direction at intervals in the circumferential direction. Each protrusion 57 is provided at a predetermined interval on the outer surface of the cylindrical portion 55 avoiding the region facing the portions 51a and 51b of the cylindrical wall portion 51 located in the same orientation as the five virtue claws and the location where the engaging projection 56 is provided. Each is provided so as to extend straight in the vertical direction from the upper end of the cylindrical portion 55 to directly above the portion of the cylindrical portion 55 that fits inside the seal portion 42a of the burner body 4. Further, the upper end portion 57 a of each protrusion 57 is provided so as to straddle the lower surface of the burner cap 5. Further, a portion between the cylindrical portion 55 and the cylindrical wall portion 51 on the lower surface of the burner cap 5 has a concave portion 50 that is recessed above the upper end 520 of the flame hole 52a having a relatively large vertical dimension.
以上の実施形態によれば、混合管3から、外筒部41と内筒部42との間の空間43へと供給された混合気がバーナキャップ5の下面の下を通って各炎孔から噴出すると共に、筒部55内の空間を介して炎孔から噴出する混合気に二次空気が供給されてコンロ用バーナBuが燃焼する。バーナ燃焼時、特に、バーナキャップ5の炎孔の近傍が加熱されるが、筒部55の上端からのシール部42aに内嵌する筒部55の部分の直上までのびるように複数の突条57を設けることにより、炎孔に供給される混合気と筒部55との接触面積が増加して筒部55が混合気で効率よく冷却され、この筒部55へと熱引けすることで、バーナキャップ5が融点以上に過熱されることはない。つまり、本実施形態では、混合気でバーナキャップ5を冷却して過熱防止されるため、上記従来例の如く、バーナキャップ5の上面に殊更突条を設ける必要がなく、平坦な面に形成されている。このため、バーナキャップ5上に零れ落ちた煮汁を簡単に払拭することができ、バーナキャップ5のお手入れは簡単である。また、各突条57の上端部57aをバーナキャップ5の下面に跨るようにしたため、煮汁がバーナキャップ5の上面に落下し、バーナキャップ5の上面が急冷されて熱収縮しても、突条57が補強リブとして機能することで、バーナキャップ5に反りが生じることを抑制できる。更に、バーナキャップ5下面に上方に窪んだ凹部50を有するため、筒部55と筒壁部51との間で凹部50に回り込むようにして混合気が流れ、バーナキャップ5に対する混合気の接触面積が増加してバーナキャップ5の過熱を一層確実に防止することができる。   According to the above embodiment, the air-fuel mixture supplied from the mixing tube 3 to the space 43 between the outer cylinder portion 41 and the inner cylinder portion 42 passes under the lower surface of the burner cap 5 from each flame hole. While being ejected, secondary air is supplied to the air-fuel mixture ejected from the flame hole through the space in the cylindrical portion 55, and the stove burner Bu burns. During burner combustion, in particular, the vicinity of the flame hole of the burner cap 5 is heated. Is provided, the contact area between the air-fuel mixture supplied to the flame hole and the cylindrical portion 55 is increased, the cylindrical portion 55 is efficiently cooled with the air-fuel mixture, and the heat is drawn into the cylindrical portion 55, whereby the burner The cap 5 is not overheated above the melting point. That is, in the present embodiment, the burner cap 5 is cooled by the air-fuel mixture to prevent overheating, so that it is not necessary to provide a special protrusion on the upper surface of the burner cap 5 as in the above-described conventional example, and the flat surface is formed. ing. For this reason, the spilled soup on the burner cap 5 can be easily wiped off, and the burner cap 5 is easy to clean. Further, since the upper end portion 57a of each protrusion 57 extends over the lower surface of the burner cap 5, even if the broth falls on the upper surface of the burner cap 5 and the upper surface of the burner cap 5 is rapidly cooled and thermally contracted, the protrusions Since 57 functions as a reinforcing rib, it is possible to prevent the burner cap 5 from warping. Further, since the concave portion 50 is recessed upward on the lower surface of the burner cap 5, the air-fuel mixture flows around the concave portion 50 between the tube portion 55 and the tube wall portion 51, and the contact area of the air-fuel mixture with respect to the burner cap 5. And the overheating of the burner cap 5 can be more reliably prevented.
以上、本実施の形態のコンロ用バーナについて説明したが、本発明は、上記のものに限定されるものではない。上記実施形態では、バーナキャップ5の製造(鋳造)を考慮して、各五徳爪と同一方位に位置する筒壁部51の部分51a,51bに対向する領域と係合突起56を設けた箇所とを避けて筒部55の外表面に突条57を設けたものを例に説明したが、寸法上の制約を受けないような場合には当該領域にも突条57を設けることができる。また、各突条57を形成する数や上下方向の長さはバーナの能力等を考慮して適宜選択することができ、更に、上記実施形態では、各突条57が、上下方向に真直にのびるものを例に説明したが、これに限定されるものではなく、各突条57を周方向に傾斜させながら上下方向にのびるようにしてもよい。   Although the stove burner of the present embodiment has been described above, the present invention is not limited to the above. In the above embodiment, in consideration of the manufacture (casting) of the burner cap 5, the areas facing the portions 51 a and 51 b of the cylindrical wall portion 51 located in the same orientation as the five virtue claws and the places where the engagement protrusions 56 are provided In the above example, the protrusions 57 are provided on the outer surface of the cylindrical portion 55. However, the protrusions 57 can also be provided in the region when the dimensions are not restricted. Further, the number of the protrusions 57 and the length in the vertical direction can be appropriately selected in consideration of the ability of the burner and the like, and in the above embodiment, the protrusions 57 are straight in the vertical direction. Although the example of extending is described above, the present invention is not limited to this, and the protrusion 57 may be extended in the vertical direction while being inclined in the circumferential direction.
