Description

【0001】
【発明の属する技術分野】
本発明は、ガスコンロに用いられるコンロ用バーナの近傍に、炎検知器及び点火電極を固定する構造に関するものである。
【0002】
【従来の技術】
図5は、従来のガスコンロのケーシング(図示せず)内に配設されるコンロ用バーナの分解斜視図である。
燃料ガスと一次空気を混合するベンチュリ(1)の下流端から屈曲起立する円筒状頭部(12)には、バーナボディ(2)が取付ビス(20)(20)で取付けられるようになっており、これらベンチュリ(1)とバーナボディ(2)によってバーナ本体(A)が構成されている。
【0003】
バーナボディ(2)の上面中央部には、円筒状のバーナヘッド装着筒(21)が隆起していると共に、該バーナヘッド装着筒(21)の上端のバーナヘッド歯載置面(24)には、バーナヘッド(3)が歯(31)部分で載置されるようになっている。
【0004】
更に、バーナボディ(2)に装着されるバーナヘッド(3)の下面には、中央筒(33)と、その外側の炎孔形成用の歯(31)(31)と、点火及び炎監視用の炎孔を形成する補助歯(32)(32)と、後述の点火電極(I)に対応する放電用ターゲット(34)が設けられている。
【0005】
又、バーナボディ(2)のバーナヘッド歯載置面(24)には、ベンチュリ(1)に取付けられた炎検知器(TC)や点火電極(I)を挿通させる為の挿通切欠(29)が上下に貫通している。
【0006】
前記炎検知器(TC)や点火電極(I)は、これらを挟持するプラグホルダ(61)(62)によって止め板(5)に取付けられている。このプラグホルダ(61)(62)は、バネ板を二つ折りに屈曲させたものであり、その屈曲中央部に位置する差込頭部(65)と、該差込頭部(65)の基端側に連続し且つ互いに対向する円弧状の湾曲挟持部(66)(66)を備えている。
【0007】
このものでは、上記プラグホルダ(61)(62)の差込頭部(65)(65)を止め板(5)の保持孔(51)(52)に嵌入した後、湾曲挟持部(66)(66)に炎検知器(TC)や点火電極(I)を強制的に嵌入する。すると、炎検知器(TC)や点火電極(I)がプラグホルダ(61)(62)を介して止め板(5)の保持孔(51)(52)部分に取付けられる。

【発明が解決しようとする課題】
しかしながら、上記従来のものでは、プラグホルダ(61)(62)の一端が開放しているから、湾曲挟持部(66)(66)で挟持された炎検知器(TC)や点火電極(I)に対して前記開放部側に外力が作用すると、これらが湾曲挟持部(66)(66)から脱出し、点火電極(I)がバーナヘッド(3)の下面の放電用ターゲット(34)に対向しなくなると共に、炎検知器(TC)が炎監視用の炎孔(補助歯(32)(32)の配設部)に対向しなくなり、これにより、点火や炎監視の精度低下を招来する。このように、上記従来のものでは、外力に対して炎検知器(TC)や点火電極(I)が不安定であるという問題があった。
【0010】
又、プラグホルダ(61)(62)が、炎検知器(TC)と点火電極(I)の夫々に対して各別に必要となるから、その分、部品点数が多くなるという問題もあった。
【0011】
本発明は、かかる点に鑑みて成されたもので、
『止め板に、棒状の炎検知器(TC)と点火電極(I)を上下向きに固定する構造』に於いて、炎検知器(TC)や点火電極(I)の固定状態の安定性を向上させると共に、必要部品数を少なくできるようにすることを課題とする。
【0012】
【課題を解決するための手段】
[1項]
上記課題を解決するための本発明の技術的手段は、
『前記止め板は、中央起立板と該中央起立板の水平方向の両端部から互いに表裏反対方向に屈曲する第1屈曲板と第2屈曲板を備えており、
前記中央起立板に開設されたバネ挿通口を表裏に貫通するバネ部材の長手方向の両端が、前記第1,第2屈曲板の夫々に設けられた第1,第2係合部に各別に着脱自在に係合され、
前記第1,第2屈曲板の夫々と前記中央起立板との境界の各コーナ部内面と前記バネ部材によって前記炎検知器(TC)と点火電極(I)が各別に挟圧保持される』ことである。
上記技術的手段によれば、上下姿勢で取付けられる棒状の炎検知器(TC)と点火電極(I)が、第1屈曲板と第2屈曲板の夫々と中央起立板との境界の各コーナ部内面とバネ部材によって挟圧抱持される。これにより、炎検知器(TC)と点火電極(I)の一方が、上記コーナ部の稜線に沿う態様で、第1屈曲板と中央起立板とバネ部材の三者で挟圧される。これにより、既述従来のプラグホルダ(61)(62)の一端の開放部(点火電極(I)等の脱落原因になる部分)に相当するものが無くなる。又、他方の炎検知器(TC)又は点火電極(I)が,第2屈曲板と中央起立板とバネ部材の三者で挟圧される。従って、炎検知器(TC)等が平面板とバネ部材の二者で挟圧される場合に比べて、固定状態が安定する。
【0013】
又、炎検知器(TC)と点火電極(I)の2つの部品を単一のバネ部材で固定するから、これら炎検知器(TC)と点火電極(I)の夫々に対してプラグホルダ(61)(62)が各別に必要であった既述従来のものに比べて必要部品点数が少なくなる。
【0014】
[2項]
前記1項に於いて、
『前記バネ挿通口は、前記中央起立板の上辺又は下辺に開放しており、
前記第1係合部は、前記バネ部材の一端を挿抜自在に差し込む為に前記第1屈曲板に形成された透孔であり、
前記第2係合部は、前記第2屈曲板の水平方向の先端に開放する水平スリット部と、該水平スリット部の奥端部から上方又は下方に屈曲するバネ係合スリット部とから構成されている』ものでは、次の様に炎検知器(TC)又は点火電極(I)の組み付け作業を行なうことができる。
【0015】
先ず、第1屈曲板と中央起立板の境界のコーナ部内面に炎検知器(TC)又は点火電極(I)を当接させた状態で、第1屈曲板の透孔にバネ部材の一端を挿通する。
【0016】
次に、中央起立板の上辺又は下辺に開放するバネ挿通口の上端又は下端の開放部から、バネ部材の長手方向の中央部を挿入する。
【0017】
その後、第2屈曲板と中央起立板の境界のコーナ部に残余の点火電極(I)又は炎検知器(TC)を当接させ、この状態で、バネ部材の他端を、第2屈曲板の先端に開放する水平スリット部に沿ってその奥側に移動させ、更にその奥端部からバネ係合スリット部に沿って上下に移動させると、該バネ部材の他端が第2屈曲板に係合保持される。これにより、第1屈曲板と第2屈曲板の夫々と前記中央起立板との境界の各コーナ部内面と前記バネ部材によって、前記炎検知器(TC)と点火電極(I)が各別に挟圧保持された状態になる。
【0018】
[3項]
前記1項に於いて、
『前記バネ挿通口は、前記中央起立板の上辺又は下辺に開放しており、
前記第1係合部は、前記第1屈曲板に形成され且つ前記バネ挿通口の前記開放方向と同方向に開放する上下スリット部と、該上下スリット部の奥端部から横方向へ延長されたバネ係合スリット部とから構成されており、
前記第2係合部は、前記第2屈曲板に形成され且つ前記バネ挿通口の前記開放方向と同方向に開放する上下スリット部と、該上下スリット部の奥端部から横方向へ延長されたバネ係合スリット部とから構成されている』ものとすることができる。
このものでは、中央起立板に形成されたバネ挿通口と、第1,第2屈曲板の夫々に形成された上下スリット部は同方向(上辺側又は下辺側)に開放している。従って、中央起立板と第1,第2屈曲板の境界部の各コーナ部内面に炎検知器(TC)と点火電極(I)を当接させた状態で、上記バネ挿通口と各上下スリット部に、バネ部材の中央部及び両端近傍を上下方向からスライドさせるように押し込むことができる。そして、バネ部材の両端近傍が、第1,第2屈曲板に形成された上下スリットの奥端部から横方向へ延長されたバネ係合スリット部に到達したときに、該バネ部材がその復元力によって初期形状に復帰しようとし、これにより、バネ係合スリット部内に係合する。これにより、炎検知器(TC)と点火電極(I)がバネ部材で止め板に固定される。
【0019】
[4項]
前記1項〜3項に於いて、
『前記バネ部材は、一端が折り返されてツマミ部となった線状バネである』ものでは、ツマミ部を摘んで線状バネを取り扱うことができるから、ツマミ部を有しない単純な線状バネに比べて取り扱いが容易に行なえる。
【0020】
[5項]
前記1項〜3項に於いて、
『前記バネ部材は、二本の平行な直線部の一端が繋がったU字状バネである』ものでは、二本の直線部で炎検知器(TC)及び点火電極(I)を止め板側に押圧することができる。従って、一本の線状バネの場合に比べて炎検知器(TC)及び点火電極(I)を一層安定的に固定できる。
【0021】
[6項]
前記1項〜3項に於いて、
『前記バネ部材は、一方に長い帯状の板バネである』ものでは、バネ部材として線状バネを採用する場合に比べ、バネ部材が炎検知器(TC)や点火電極(I)の外周面に対して広い範囲に亘って接触する。従って、線状バネを採用する場合に比べて、炎検知器(TC)や点火電極(I)の安定性が一層向上する。
【0022】
【発明の効果】
本発明は次の特有の効果を有する。
炎検知器(TC)や点火電極(I)が、第1屈曲板又は第2屈曲板と中央起立板とバネ部材の三者で挟圧抱持されるから、既述従来のプラグホルダ(61)(62)の一端の開放部(点火電極(I)等の脱落原因になる部分)に相当するものが無くなり、点火電極(I)等の取付け姿勢が安定する。
【0023】
又、棒状の炎検知器(TC)と点火電極(I)が、上記コーナ部の稜線に沿う態様で、該コーナ部に対してバネ部材によって押圧されるから、既述したように、平面部にバネ部材で押圧する構造を採用する場合に比べて、取付け姿勢が安定する。
【0024】
炎検知器(TC)と点火電極(I)の2つの部品を単一のバネ部材で固定するから、これら炎検知器(TC)と点火電極(I)の夫々に対してプラグホルダ(61)(62)が各別に必要であった既述従来のものに比べて必要部品点数が少なくなる。
【0025】
2項のものでは、バネ挿通口が中央起立板の上辺又は下辺に開放しているから、該開放部を介してバネ部材をバネ挿通口に挿通させることができる。又、バネ部材の一端は、第2屈曲板の先端に開放する第2係合部を構成する水平スリットの先端開放部から、該水平スリットにスライドさせるように押し込み、その後、前記水平スリットの奥端部に連続するバネ係合スリット部に係合させることができる。従って、バネ挿通口や第2係合部として、単純な透孔を採用する場合に比べ、バネ部材の取付け作業を円滑に行える。
【0026】
3項のものでは、中央起立板と第1,第2屈曲板に形成されたバネ挿通口や上下スリット部に対して、バネ部材を全体的に上下方向からスライドさせるように押し込むことができるから、バネ部材の取付け作業が一層円滑に行なえる。
【0027】
4項のものでは、ツマミ部を摘むことができるから、単純な線状バネに比べて取り扱いが容易になる。
【0028】
5項のものでは、バネ部材として、二本の平行な直線部を備えたU字状バネを採用するから、一本の線状バネの場合に比べて炎検知器(TC)及び点火電極(I)を一層安定的に固定できる。
【0029】
6項のものでは、バネ部材として帯状の板バネを採用するから、前記5項のものと同様に、一本の線状バネの場合に比べて炎検知器(TC)及び点火電極(I)の取付け姿勢が一層安定する。
【0030】

上記ベンチュリ(1)の円筒状頭部(12)に取付けられるバーナボディ(2)は、本実施の形態では真鍮等の金属で製作されており、その構造は既述従来のものと同様に構成されているので、既に説明した構成の記載は、これを援用する。
【0040】
バーナボディ(2)の上面中央に突設されたバーナヘッド装着筒(21)の上端面は、中心に向かって低くなっており、これにより、バーナヘッド(3)を載置する為のバーナヘッド歯載置面(24)及び補助歯載置面(24a)が形成されている。そして、バーナヘッド(3)を載置することにより後述の歯(31)や補助歯(32)で点火用炎孔等が形成される。又、バーナヘッド装着筒(21)の内周壁には、バーナボディバーナヘッド(3)の周方向の位置決めを行なう為の係合溝(22)が形成されており、該係合溝(22)には、後述のバーナヘッド(3)の下面に突設された位置決め突起(35)が嵌入するようになっている。

尚、バーナヘッド(3)の下面に形成された補助歯(32)は、補助歯載置面(24a)に載置される。
【0043】
[組み立て作業]
本実施の形態に係るガスコンロは、該ガスコンロのケーシング(図示せず)とこれに組み込まれる上記コンロ用バーナを備えている。
【0044】
次に、上記各部品を用いてコンロ用バーナを組み立てる作業を説明する。
先ず、事前に、止め板(5)に炎検知器(TC)と点火電極(I)を組み付ける。
具体的には、止め板(5)を構成する中央起立板(54)と第1屈曲板(55)の境界部のコーナ部内面に炎検知器(TC)を沿わせ、この状態で、バネ部材(4)の直線部(40)の先端を第1屈曲板(55)の透孔(550)に挿入した後、該直線部(40)を炎検知器(TC)の外周溝(F)に嵌めると共に、該直線部(40)を中央起立板(54)のバネ挿通口(540)に上方から挿入する。すると、バネ部材(4)の弾性により、中央起立板(54)と第1屈曲板(55)の境界部のコーナ部内面とバネ部材(4)で炎検知器(TC)が挟圧保持された状態になる。即ち、炎検知器(TC)が、上記コーナ部の稜線に沿う態様で、該コーナ部に対してバネ部材(4)によって押圧される。
【0045】
次に、止め板(5)を構成する中央起立板(54)と第2屈曲板(56)の境界部のコーナ部内面に点火電極(I)を沿わせ、この状態で、バネ部材(4)の直線部(40)を水平スリット部(560)からバネ係合スリット部(561)に移動させると、点火電極(I)の外周溝(G)に上記直線部(40)が嵌入する。すると、バネ部材(4)の弾性により、中央起立板(54)と第2屈曲板(56)の境界部のコーナ部内面とバネ部材(4)で点火電極(I)が挟圧保持された状態になる。即ち、点火電極(I)が、上記コーナ部の稜線に沿う態様で、該コーナ部に対してバネ部材(4)によって押圧される。
【0046】
従って、本実施の形態では、上下に長い棒状の炎検知器(TC)と点火電極(I)が、上記コーナ部内面の稜線に沿う態様で、該コーナ部に対してバネ部材によって押圧されるから、平面部にバネ部材で押圧する構造を採用する場合に比べて、取付け姿勢が安定する。
【0047】
又、炎検知器(TC)と点火電極(I)の2つの部品を単一のバネ部材(4)で固定するから、これら炎検知器(TC)と点火電極(I)の夫々に対してプラグホルダ(61)(62)が各別に必要であった既述従来のものに比べて必要部品点数が少なくなる。
【0048】
次に、炎検知器(TC)と点火電極(I)が取付けられた止め板(5)をベンチュリ(1)に固定する。具体的には、止め板(5)の上辺から水平方向に屈曲する水平片(55a)(56a)に開設されたネジ挿通孔(55b)(56b)部分を、これに対応するベンチュリ(1)側の柱体(14)(14)のネジ孔(140)(140)部分に重ね合わせ、該重ね合わせ部をビス(15)(15)で固定する。
【0049】
次に、ベンチュリ(1)の円筒状頭部(12)に形成されたネジ孔(111)(111)に対して、バーナボディ(2)に貫設された取付ビス(20)用の挿通孔(250)(250)を合致させ、この部分に取付ビス(20)(20)を螺入して締め付ける。
【0050】
その後、バーナヘッド(3)の下面の中央筒(33)をバーナボディ(2)の中心軸(28)に遊嵌させる。このとき、バーナヘッド(3)の下面外周側に突設された位置決め突起(35)を、これに対応するバーナボディ(2)側の係合溝(22)に嵌入させ、これにより、バーナヘッド(3)の周方向の位置決めを行なう。すると、バーナヘッド(3)の下面の(34)が点火電極(I)の上端に対向すると共に、炎監視用の炎孔を形成する補助歯(32)(32)部分が炎検知器(TC)の上端に対向し、これにより、本実施の形態に適用されるコンロ用バーナが完成する。
尚、水平スリット部(560)とバネ係合スリット部(561)の組、及び、バネ挿通口(540)の夫々に代えて、単純な透孔を形成してもよい。
【0051】

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a structure for fixing a flame detector and an ignition electrode near a stove burner used for a gas stove.
[0002]
[Prior art]
FIG. 5 is an exploded perspective view of a stove burner provided in a conventional gas stove casing (not shown).
A burner body (2) is attached to a cylindrical head (12) that rises from the downstream end of a venturi (1) that mixes fuel gas and primary air with attachment screws (20) (20). The venturi (1) and the burner body (2) constitute a burner body (A).
[0003]
At the center of the upper surface of the burner body (2), a cylindrical burner head mounting cylinder (21) is raised, and the burner head mounting cylinder (21) has a burner head tooth mounting surface (24) at the upper end thereof. Is designed so that the burner head (3) is mounted on the teeth (31).
[0004]
Further, on the lower surface of the burner head (3) mounted on the burner body (2), a central cylinder (33), teeth (31) (31) for forming a flame hole outside thereof, and ignition and flame monitoring. Auxiliary teeth (32) and (32) for forming a flame hole and a discharge target (34) corresponding to an ignition electrode (I) to be described later are provided.
[0005]
A notch (29) for inserting a flame detector (TC) and an ignition electrode (I) attached to the venturi (1) into the burner head tooth mounting surface (24) of the burner body (2). Penetrates up and down.
[0006]
The flame detector (TC) and the ignition electrode (I) are attached to the stopper plate (5) by plug holders (61) and (62) which hold them. The plug holders (61) and (62) are obtained by bending a spring plate into two folds. A plug head (65) located at the center of the spring plate and a base of the plug head (65) are provided. An arc-shaped curved holding portion (66) (66) which is continuous with the end side and faces each other is provided.
[0007]

[0009]
[Problems to be solved by the invention]
However, in the above-described conventional device, since one end of the plug holder (61) (62) is open, the flame detector (TC) and the ignition electrode (I) held by the curved holding portions (66) (66). When an external force acts on the open portion side, these escape from the curved holding portions (66) and (66), and the ignition electrode (I) faces the discharge target (34) on the lower surface of the burner head (3). At the same time, the flame detector (TC) does not face the flame hole for flame monitoring (the portion where the auxiliary teeth (32) and (32) are disposed), thereby causing a decrease in the accuracy of ignition and flame monitoring. As described above, the above-described conventional apparatus has a problem that the flame detector (TC) and the ignition electrode (I) are unstable with respect to an external force.
[0010]
Further, since the plug holders (61) and (62) are required separately for the flame detector (TC) and the ignition electrode (I), there is also a problem that the number of parts increases accordingly.
[0011]
The present invention has been made in view of such a point,
In the "structure in which the rod-shaped flame detector (TC) and the ignition electrode (I) are vertically fixed to the stopper plate", the stability of the fixed state of the flame detector (TC) and the ignition electrode (I) is improved. It is an object to improve the number of components and to reduce the number of required components.
[0012]
[Means for Solving the Problems]
[1]
Technical means of the present invention for solving the above problems,
"The stopper plate includes a central upright plate and a first bent plate and a second bent plate that are bent in opposite directions to each other from both ends in the horizontal direction of the central upright plate,
Both ends in the longitudinal direction of a spring member that penetrates the spring insertion opening formed in the central upright plate from front to back are separately provided on first and second engagement portions provided on the first and second bent plates, respectively. Detachably engaged,
The flame detector (TC) and the ignition electrode (I) are separately clamped and held by the inner surface of each corner portion at the boundary between each of the first and second bent plates and the central upright plate and the spring member. " That is.
According to the above technical means, the rod-shaped flame detector (TC) and the ignition electrode (I) mounted in the up and down posture are provided at the respective corners of the boundaries between the first bent plate and the second bent plate and the central upright plate. It is squeezed and held by the inner surface and the spring member. Thereby, one of the flame detector (TC) and the ignition electrode (I) is pressed by the three members of the first bent plate, the central upright plate, and the spring member in a manner along the ridgeline of the corner portion. As a result, the portion corresponding to the open portion at one end of the conventional plug holders (61) and (62) (the portion that causes the ignition electrode (I) or the like to fall off) is eliminated. Further, the other flame detector (TC) or the ignition electrode (I) is pinched by the three members of the second bent plate, the center standing plate, and the spring member. Therefore, the fixed state is stabilized as compared with the case where the flame detector (TC) or the like is pressed between the flat plate and the spring member.
[0013]
Further, since the two parts of the flame detector (TC) and the ignition electrode (I) are fixed by a single spring member, a plug holder () is attached to each of the flame detector (TC) and the ignition electrode (I). 61) and (62), the required number of parts is reduced as compared with the above-described conventional one which is separately required.
[0014]
[2]
In the above item 1,
`` The spring insertion opening is open on the upper side or the lower side of the central upright plate,
The first engagement portion is a through hole formed in the first bent plate for inserting one end of the spring member so as to be freely inserted and removed,
The second engagement portion includes a horizontal slit portion that opens to a horizontal end of the second bent plate, and a spring engagement slit portion that is bent upward or downward from a deep end of the horizontal slit portion. In this case, the work of assembling the flame detector (TC) or the ignition electrode (I) can be performed as follows.
[0015]
First, with the flame detector (TC) or the ignition electrode (I) in contact with the inner surface of the corner portion at the boundary between the first bent plate and the center standing plate, one end of the spring member is inserted into the through hole of the first bent plate. Insert.
[0016]
Next, the central part in the longitudinal direction of the spring member is inserted from the upper end or the lower end of the spring insertion opening that opens to the upper side or the lower side of the central upright plate.
[0017]
Thereafter, the remaining ignition electrode (I) or flame detector (TC) is brought into contact with a corner portion at the boundary between the second bent plate and the center standing plate. In this state, the other end of the spring member is connected to the second bent plate. When it is moved to the back side along the horizontal slit part opened to the tip of the head, and further moved up and down along the spring engagement slit part from the back end part, the other end of the spring member is moved to the second bent plate. The engagement is maintained. Thus, the flame detector (TC) and the ignition electrode (I) are sandwiched between the inner surfaces of the corners at the boundaries between the first bent plate and the second bent plate and the center standing plate and the spring member. The pressure is maintained.
[0018]
[3]
In the above item 1,
`` The spring insertion opening is open on the upper side or the lower side of the central upright plate,
The first engagement portion is formed in the first bent plate and is opened and closed in the same direction as the opening direction of the spring insertion port. The upper and lower slit portions are extended laterally from the innermost end of the upper and lower slit portions. And a spring engaging slit portion.
The second engaging portion is formed in the second bent plate and opens in the same direction as the opening direction of the spring insertion port. The upper and lower slit portions extend in the lateral direction from the deep end of the upper and lower slit portions. And a spring engaging slit portion. "
In this device, the spring insertion opening formed in the central upright plate and the upper and lower slit portions formed in each of the first and second bent plates are open in the same direction (upper side or lower side). Therefore, in a state where the flame detector (TC) and the ignition electrode (I) are brought into contact with the inner surfaces of the corners at the boundary between the central upright plate and the first and second bent plates, the spring insertion port and each of the upper and lower slits The center portion and the vicinity of both ends of the spring member can be pushed into the portion so as to slide from the up and down direction. Then, when the vicinity of both ends of the spring member reaches a spring engaging slit portion extending in the lateral direction from the deep ends of the upper and lower slits formed in the first and second bending plates, the spring member is restored. An attempt is made to return to the initial shape by force, thereby engaging in the spring engagement slit portion. Thereby, the flame detector (TC) and the ignition electrode (I) are fixed to the stopper plate by the spring member.
[0019]
[Item 4]
In the above items 1 to 3,
In the “the spring member is a linear spring having one end turned into a knob portion”, a simple linear spring having no knob portion can be handled by pinching the knob portion. It is easier to handle than.
[0020]
[5]
In the above items 1 to 3,
In the "the spring member is a U-shaped spring in which one end of two parallel straight portions is connected", the flame detector (TC) and the ignition electrode (I) are stopped by the two straight portions. Can be pressed. Therefore, the flame detector (TC) and the ignition electrode (I) can be fixed more stably as compared with the case of one linear spring.
[0021]
[Section 6]
In the above items 1 to 3,
In the case where the “spring member is a long band-shaped leaf spring”, the outer peripheral surface of the flame detector (TC) or the ignition electrode (I) is different from the case where a linear spring is adopted as the spring member. Contact over a wide area. Therefore, the stability of the flame detector (TC) and the ignition electrode (I) is further improved as compared with the case where a linear spring is employed.
[0022]
【The invention's effect】
The present invention has the following specific effects.
Since the flame detector (TC) and the ignition electrode (I) are clamped and held by the first bent plate or the second bent plate, the center standing plate and the spring member, the conventional plug holder (61) described above is used. (62) There is no equivalent to the open portion at one end (the portion that causes the ignition electrode (I) or the like to fall off), and the mounting posture of the ignition electrode (I) or the like is stabilized.
[0023]
Further, since the rod-shaped flame detector (TC) and the ignition electrode (I) are pressed against the corner by a spring member along the ridge line of the corner, as described above, the flat part is formed. The mounting posture is stable as compared with the case where a structure in which the spring member is pressed is adopted.
[0024]
Since the two parts of the flame detector (TC) and the ignition electrode (I) are fixed by a single spring member, the plug holder (61) is provided for each of the flame detector (TC) and the ignition electrode (I). The number of required parts is reduced as compared with the above-described conventional one which requires (62) separately.
[0025]
According to the second aspect, since the spring insertion opening is open to the upper side or the lower side of the central standing plate, the spring member can be inserted through the opening through the opening. Further, one end of the spring member is pushed into the horizontal slit from the open end of the horizontal slit constituting the second engaging portion that opens to the end of the second bent plate so as to slide into the horizontal slit. It can be engaged with a spring engagement slit portion that is continuous with the end portion. Therefore, the operation of attaching the spring member can be performed more smoothly than when a simple through hole is used as the spring insertion port or the second engagement portion.
[0026]
In the item (3), the spring member can be pushed into the spring insertion opening and the upper and lower slit portions formed in the central upright plate and the first and second bent plates so as to slide the spring member as a whole from the vertical direction. The work of attaching the spring member can be performed more smoothly.
[0027]
In the case of the item (4), since the knob portion can be picked, the handling becomes easier as compared with a simple linear spring.
[0028]
In the item (5), since a U-shaped spring having two parallel straight portions is employed as the spring member, the flame detector (TC) and the ignition electrode (TC) are compared with a single linear spring. I) can be fixed more stably.
[0029]
In the item (6), a strip-shaped leaf spring is used as the spring member. Therefore, similar to the item (5), the flame detector (TC) and the ignition electrode (I) are different from those in the case of one linear spring. The mounting posture of is more stable.
