Description

本発明は、テーブルコンロ等のガスコンロに組み込まれる、こんろ用バーナに関するものである。   The present invention relates to a stove burner incorporated in a gas stove such as a table stove.

従来のこんろ用バーナとして、図４に示すように、環状のバーナヘッド(1)にバーナキャップ(2)が載置された構成のものがある（特許文献１参照）。
環状のバーナヘッド(1)の上面外周部に形成されたテーパ座面(11)は中心に向けて次第に高くなっていると共に、該テーパ座面(11)には、バーナキャップ(2)の下面外周部の環状壁(21)が載置されている。 As a conventional stove burner, there is one having a configuration in which a burner cap (2) is placed on an annular burner head (1) as shown in FIG. 4 (see Patent Document 1).
The tapered seat surface (11) formed on the outer periphery of the upper surface of the annular burner head (1) is gradually higher toward the center, and the tapered seat surface (11) has a lower surface of the burner cap (2). An annular wall (21) at the outer periphery is placed.

バーナキャップ(2)の前記環状壁(21)の上端近傍には外端の炎口(22)に向かって上昇する炎口用通路(20)が貫通していると共に、環状壁(21)の下面には煮汁戻し溝(23)が形成されている。
又、バーナヘッド(1)の上面に形成されたテーパ座面(11)の内周部(110)は、前記煮汁戻し溝(23)や炎口用通路(20)の内端より更に内方に迫出している。
このものでは、炎口用通路(20)を炎口(22)に向かって上昇するように傾斜させたから、燃料ガスが上向きに噴出され、これにより、鍋等の加熱に適した上向き姿勢の火炎(F)が生成される。 In the vicinity of the upper end of the annular wall (21) of the burner cap (2), a flame passage (20) rising toward the outer flame port (22) penetrates, and the annular wall (21) A broth return groove (23) is formed on the lower surface.
Further, the inner peripheral portion (110) of the tapered seat surface (11) formed on the upper surface of the burner head (1) is further inward from the inner ends of the broth return groove (23) and the flame port (20). Rushed out.
In this case, since the flame passage (20) is inclined so as to rise toward the flame mouth (22), the fuel gas is jetted upward, and thus the flame in an upward posture suitable for heating a pan or the like (F) is generated.

一方、鍋から溢れた煮汁(A)が炎口(22)から炎口用通路(20)内に流入すると、これがバーナヘッド(1)上端のテーパ座面(11)の内周部(110)で受け止められ、外方へ低くなったテーパ座面(11)に案内されつつ煮汁戻し溝(23)を通過して外部へ排出される。
特開平１１−６３５０２号公報 On the other hand, when the broth (A) overflowing from the pan flows from the flame opening (22) into the flame opening passage (20), this is the inner peripheral part (110) of the tapered seating surface (11) at the upper end of the burner head (1). Is passed through the broth return groove (23) while being guided by the taper seat surface (11) which is lowered outward, and discharged to the outside.

以下に、本発明を実施するための最良の形態について添付図面を参照しながら説明する。
［第１実施形態］
本発明の第１実施形態に係るこんろ用バーナ(B)は、図１に示すように、ガスこんろ用のこんろ天板(3)に開設されたバーナ用開口(31)から上方に突出する態様で設けられている。こんろ天板(3)上には、こんろ用バーナ(B)を包囲する位置に五徳(4)が配設されている。 The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
[First Embodiment]
The stove burner (B) according to the first embodiment of the present invention, as shown in FIG. 1, is located upward from the burner opening (31) opened in the gas stove top plate (3). It is provided in a protruding manner. On the stove top (3), the five virtues (4) are arranged in a position surrounding the stove burner (B).

こんろ用バーナ(B)は、環状のバーナヘッド(1)とその下方に連設される混合管(5)から構成されたバーナボディ(6)を有していると共に、バーナヘッド(1)上にはこれと同一外径を有するバーナキャップ(2)が重ね合わせ状態に載置されている。   The stove burner (B) has a burner body (6) composed of an annular burner head (1) and a mixing pipe (5) provided below the annular burner head (1), and the burner head (1). On the top, a burner cap (2) having the same outer diameter is placed in an overlapping state.

混合管(5)は、同心状の内・外筒(51)(52)から成る二重筒部(53)がスロート部(50)の下流端に連設された構造である。
混合管(5)の上方に連設されるバーナヘッド(1)は、前記二重筒部(53)の上端に接続される内・外筒(16)(15)からなる二重筒部(17)を備えている。外筒(15)と内筒(16)の相互間には、両者を結合する結合片(a)が周方向に所定ピッチで設けられている。 The mixing pipe (5) has a structure in which a double cylinder part (53) composed of concentric inner and outer cylinders (51) and (52) is connected to the downstream end of the throat part (50).
The burner head (1) provided continuously above the mixing pipe (5) is a double cylinder part comprising inner and outer cylinders (16) (15) connected to the upper end of the double cylinder part (53). 17). Between the outer cylinder (15) and the inner cylinder (16), coupling pieces (a) for coupling both are provided at a predetermined pitch in the circumferential direction.

前記外筒(15)と内筒(16)の相互の間隙は、混合管(5)内に繋がるガス通路(13)となっており、その下流端開口(130)はバーナキャップ(2)の下面に対向している。これにより、バーナヘッド(1)とバーナキャップ(2)の重ね合わせ境界部に前記ガス通路(13)が開放した構成になっている。   The gap between the outer cylinder (15) and the inner cylinder (16) serves as a gas passage (13) connected to the mixing pipe (5), and the downstream end opening (130) of the burner cap (2) Opposite the bottom. Thus, the gas passage (13) is open at the overlapping boundary between the burner head (1) and the burner cap (2).

バーナヘッド(1)の二重筒部(17)を構成する外筒(15)の上下方向の中程には、こんろ天板(3)上に外周フランジ(18)が張り出していると共に、該外周フランジ(18)の上面外周部には環状の起立壁(14)が突設されており、該起立壁(14)と外筒(15)との間には環状凹部(19)が形成されている。   In the middle of the outer cylinder (15) constituting the double cylinder part (17) of the burner head (1), an outer peripheral flange (18) projects over the stove top (3). An annular upright wall (14) protrudes from the outer periphery of the upper surface of the outer peripheral flange (18), and an annular recess (19) is formed between the upright wall (14) and the outer cylinder (15). Has been.

起立壁(14)の上面は中心に向けて低くなるテーパ面(140)に形成されており、該テーパ面(140)の外端縁(141)は外筒(15)の上端(151)より下方に位置している。即ち、二重筒部(17)の上端に位置するガス通路(13)の下流端開口(130)は後述する炎口(22)の下端より上方に位置している。これにより、環状凹部(19)に溜まった煮汁(A)は、下流端開口(130)に流入する前に、これより下方に位置する起立壁(14)の外端縁(141)から外部に溢れるように構成されている。   The upper surface of the standing wall (14) is formed into a tapered surface (140) that decreases toward the center, and the outer end edge (141) of the tapered surface (140) is more than the upper end (151) of the outer cylinder (15). Located below. That is, the downstream end opening (130) of the gas passage (13) located at the upper end of the double cylinder portion (17) is located above the lower end of the flame port (22) described later. As a result, before the broth (A) accumulated in the annular recess (19) flows into the downstream end opening (130), it passes from the outer end edge (141) of the standing wall (14) located below to the outside. It is configured to overflow.

前記バーナヘッド(1)に載置されるバーナキャップ(2)は伏椀状に形成されていると共に、その外周部には周方向へ所定ピッチで並んだ複数の炎口(22)が開放しており、バーナヘッド(1)とバーナキャップ(2)の重ね合わせ境界部に於いて、炎口(22)から前記ガス通路(13)の下流端開口(130)に繋がる領域が炎口用通路(20)となっている。   The burner cap (2) placed on the burner head (1) is formed in a prone shape, and a plurality of flame ports (22) arranged at a predetermined pitch in the circumferential direction are opened on the outer periphery thereof. In the overlapping boundary portion of the burner head (1) and the burner cap (2), a region connecting from the flame opening (22) to the downstream end opening (130) of the gas passage (13) is a flame opening passage. (20).

バーナキャップ(2)の下面には、バーナヘッド(1)の中央部に設けられた二重筒(17)の内筒(16)に嵌入する位置決筒(26)が突設されていると共に、前記二重筒(17)の径方向外側（ガス通路(13)の下流端開口(130)の径方向外側）には位置決筒(26)と同心状の環状の垂下壁(24)が突設されている。   On the lower surface of the burner cap (2), a positioning cylinder (26) that projects into the inner cylinder (16) of the double cylinder (17) provided at the center of the burner head (1) is projected. An annular hanging wall (24) concentric with the positioning cylinder (26) is provided on the radially outer side of the double cylinder (17) (the radially outer side of the downstream end opening (130) of the gas passage (13)). Projected.

このものでは、こんろ用バーナ(B)を燃焼させると、混合管(5)から供給される燃料ガスがバーナヘッド(1)のガス通路(13)→炎口用通路(20)→バーナキャップ(2)の炎口(22)、と繋がる経路で流れて炎口(22)に火炎(F)が形成され、これにより、鍋(9)が加熱される。   In this case, when the stove burner (B) is burned, the fuel gas supplied from the mixing pipe (5) is changed from the gas passage (13) of the burner head (1) to the passage for the flame outlet (20) to the burner cap. The flame (F) is formed in the flame port (22) by flowing along the path connected to the flame port (22) of (2), and thereby the pan (9) is heated.

さて、加熱中の鍋(9)から煮こぼれが生じると、煮汁(A)が炎口(22)から炎口用通路(20)に流入して天井面(25)を伝ってバーナヘッド(1)のガス通路(13)側に流れようとする。すると、バーナキャップ(2)の天井面(25)にはガス通路(13)の下流端開口(130)より径方向外側に位置する垂下壁(24)が設けられているから、煮汁(A)は前記垂下壁(24)で堰き止められて下方に案内され、垂下壁(24)の下端から炎口用通路(20)の底部たる環状凹部(19)に落下して貯留される。すると、前述のようにガス通路(13)の下流端開口(130)が炎口(22)の下端より上方に位置しているから、環状凹部(19)に貯留された煮汁(A)はガス通路(13)の下流端開口(130)側に流入する前に、これより下方に位置する炎口(22)の下端（外周フランジ(18)の外端縁(141)）から外部に溢れる。これにより、煮汁(A)がガス通路(13)に流入するのを防止することができる。   Now, when boiling occurs from the heating pan (9), the broth (A) flows from the flame outlet (22) into the flame passage (20) and travels down the ceiling surface (25) to the burner head (1). ) To the gas passage (13) side. Then, since the hanging surface (24) located radially outside the downstream end opening (130) of the gas passage (13) is provided on the ceiling surface (25) of the burner cap (2), the broth (A) Is blocked by the drooping wall (24) and guided downward, and is dropped and stored from the lower end of the drooping wall (24) into the annular recess (19) at the bottom of the flame port (20). Then, as described above, since the downstream end opening (130) of the gas passage (13) is located above the lower end of the flame outlet (22), the broth (A) stored in the annular recess (19) is gas. Before it flows into the downstream end opening (130) side of the passage (13), it overflows to the outside from the lower end (outer end edge (141) of the outer peripheral flange (18)) of the flame port (22) located below this. Thereby, it is possible to prevent the broth (A) from flowing into the gas passage (13).

又、煮汁(A)がバーナヘッド(1)のガス通路(13)内に侵入しないから、バーナヘッド(1)の内部清掃が容易に行なえる。更に、ガス通路(13)内やその上流端に臨むガスノズルが煮汁(A)で閉塞さる心配がない。   Further, since the broth (A) does not enter the gas passage (13) of the burner head (1), the internal cleaning of the burner head (1) can be easily performed. Furthermore, there is no fear that the gas nozzle facing the gas passage (13) or the upstream end thereof will be clogged with the broth (A).

［第２実施形態]
図２は第２実施形態に係るこんろ用バーナ(B)の要部断面図であり、このものでは、バーナキャップ(2)の構造を除いて既述第１実施形態のものと同様に構成されている。
バーナキャップ(2)は、バーナヘッド(1)の中央部に設けられた内筒(16)に嵌入する位置決筒(26)の上端から水平に環状平板(27)が張り出していると共に、該環状平板(27)には上面に開放する複数の補助炎口(270)が設けられている。又、環状平板(27)の下面には外周に沿った環状壁(28)が垂下していると共に、該環状壁(28)には下方に開放するスリット(29)が周方向に多数並設されており、該スリット(29)の外端が炎口(22)になっている。又、環状壁(28)は、バーナヘッド(1)の外周フランジ(18)の上面外周に設けられた起立壁(14)に載置されるようになっている。 [Second Embodiment]

Has been. Even in this case, the broth (A) flowing into the flame outlet (22) moves to the gas passage (13) side along the ceiling surface (25) of the flame passage (20) (the lower surface of the annular flat plate (27)). Even so, it is dammed by the hanging wall (24) positioned radially outward from the outer cylinder (15) and dropped into the annular recess (19) (lower part of the flame port (20)). In this case, the upper end (151) of the outer cylinder (15) located at the center of the burner head (1), that is, the downstream end opening (130) of the gas passage (13) is located above the lower end of the flame port (22). Therefore, the boiled juice (A) stored in the annular recess (19) formed in the outer peripheral flange (18) of the burner head (1) is placed in the flame port (22) before flowing into the gas passage (13). ) To the outside.

尚、図２の想像線で示すように、バーナヘッド(1)の外周フランジ(18)に形成された環状凹部(19)に煮汁受け(41)を着脱自在に装着し、これにより、バーナヘッド(1)と前記バーナキャップ(2)の重ね合わせ境界部に煮汁受け(41)が介在する構成にしてもよい。このようにすると、垂下壁(24)から落下した煮汁(A)が煮汁受け(41)に貯留される。そして、バーナキャップ(2)を取り外すと、着脱自在な煮汁受け(41)が露出するから、該煮汁受け(41)に貯留された煮汁(A)を簡単に捨てることができる。   In addition, as shown by the imaginary line in FIG. 2, the broth receiver (41) is detachably attached to the annular recess (19) formed in the outer peripheral flange (18) of the burner head (1). A configuration is also possible in which the broth receiver (41) is interposed at the overlapping boundary between (1) and the burner cap (2). In this way, the broth (A) dropped from the drooping wall (24) is stored in the broth receiver (41). When the burner cap (2) is removed, the detachable boiled saucer (41) is exposed, so that the boiled juice (A) stored in the boiled saucer (41) can be easily discarded.

［第３実施形態]
図３は、第３実施形態に係るこんろ用バーナ(B)の要部断面図であり、このものは、板金製のバーナボディのバーナヘッド(1)部にバーナキャップ(2)を上方から嵌合したものである。このものでも、ガス通路(13)の下流端開口(130)は炎口(22)の下端より上方に形成されていると共に、炎口用通路(20)の天井面(25)にはガス通路(13)の下流端開口(130)より径方向外側に位置する垂下壁(24)が突設されている。従って、炎口用通路(20)の天井面(25)を伝ってガス通路(13)側に流れる煮汁(A)は、流動途中で垂下壁(24)で堰き止められて炎口用通路(20)の底部に落下し、その後、炎口(22)から外部に排出される。 [Third Embodiment]
FIG. 3 is a cross-sectional view of the main part of the burner burner (B) according to the third embodiment, which is composed of a burner cap (2) on the burner head (1) of the burner body made of sheet metal from above. It is a fitting. Even in this case, the downstream end opening (130) of the gas passage (13) is formed above the lower end of the flame mouth (22), and the gas passage is formed on the ceiling surface (25) of the flame passage (20). A drooping wall (24) located radially outward from the downstream end opening (130) of (13) projects. Therefore, the broth (A) flowing to the gas passage (13) side along the ceiling surface (25) of the flame passage (20) is blocked by the drooping wall (24) in the middle of the flow, and the flame passage ( It falls to the bottom of 20) and is then discharged to the outside through the flame outlet (22).
