本発明は、コンロバーナに設けられた立消安全
装置などのガス燃焼安全装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas combustion safety device such as a fire safety device provided in a stove burner.
従来の例えば熱電対素子を用いたコンロバーナ
の立消安全装置にあつては、第１図および第２図
に示すように、熱電対素子１はコンロバーナ２の
炎口３に対して平行にかつほぼ垂直に設けられて
おり、その先端部にある感熱部１ａをバーナ火炎
Ｆのうち高温部である外炎部Faへ位置させてい
るのが一般的であつた。この従来の構成では次の
欠点があつた。 In the case of a conventional fire safety device for a stove burner using, for example, a thermocouple element, as shown in FIGS. Generally, the heat sensitive part 1a at the tip of the heat sensitive part 1a is located in the outer flame part Fa which is the high temperature part of the burner flame F. This conventional configuration had the following drawbacks.
(1) バーナ火炎Ｆ中の熱電対素子１の先端部であ
る感熱部１ａは、細く、したがつて、バーナ火
炎Ｆの変動に対して感熱部１ａがバーナ火炎Ｆ
より外れやすく、所定の熱起電力の発生までの
時間（吸着保持時間）が長い。特に、コンロバ
ーナ２では回転するバーナキヤツプ４のとめら
れる位置により、炎口３と感熱部１ａの相対位
置が変動するため、その位置によつては熱起電
力が発生しないこともあつた。(1) The heat sensitive part 1a, which is the tip of the thermocouple element 1 in the burner flame F, is thin.
It comes off more easily and takes a longer time to generate a predetermined thermoelectromotive force (adsorption retention time). In particular, in the stove burner 2, the relative position between the burner port 3 and the heat-sensitive portion 1a varies depending on the position where the rotating burner cap 4 is stopped, so that depending on the position, thermoelectromotive force may not be generated.
(2) 炎口３と感熱部１２との相対位置はずれてい
ないにも関わらず、トロ火など調理物の種類に
より火力を絞つて使う場合にはバーナ火炎Ｆが
屈かず熱起電力が発生しないため、電磁安全弁
（図示せず）が閉成しコンロバーナ２が消火さ
れることもあつた。(2) Even though the relative positions of the flame opening 3 and the heat-sensitive part 12 are not shifted, when using the burner flame F to reduce the firepower depending on the type of food to be cooked, such as when using a hot fire, the burner flame F does not bend and no thermoelectromotive force is generated. As a result, an electromagnetic safety valve (not shown) was sometimes closed and the stove burner 2 was extinguished.
(3) バーナ火炎Ｆの長さは前記の場合の他に、14
種類の都市ガスと１つのLPGのガス種によつ
ても変動するとともに、供給されるガス圧力
値、あるいはダンパ調節による燃焼１次空気
量、および加熱される鍋の形状、大きさ等によ
つても変動し、従来の熱電対素子１の設置状態
では異常動作が少なくなかつた。(3) In addition to the above cases, the length of the burner flame F is 14
It varies depending on the type of city gas and LPG gas type, as well as the supplied gas pressure value, the amount of primary combustion air by adjusting the damper, and the shape and size of the pot being heated. The temperature of the thermocouple element 1 also fluctuated, and there were many abnormal operations when the conventional thermocouple element 1 was installed.
本発明は上記従来の欠点を解消することを目的
とする。すなわち、バーナ火炎に対する熱電対の
取付位置を適切にすることにより、安全弁が吸着
保持する熱起電力が発生するまでの時間を短縮

る。 The present invention aims to eliminate the above-mentioned conventional drawbacks. That is, by optimizing the mounting position of the thermocouple relative to the burner flame, the purpose is to shorten the time until the thermoelectromotive force that is attracted and held by the safety valve is generated, and to eliminate abnormal operations and malfunctions.

のである。 The gas combustion safety device of the present invention includes a burner body that is rotatably fitted in the burner body in the circumferential direction,
A circular stove burner consisting of a burner cap forming a wave-shaped flame opening at the upper end of the circumferential side, and a thermocouple element that is heated by the burner flame of the stove burner to generate thermal power and energize an electromagnetic safety valve, The heat-sensitive portion of the thermocouple element has an angle of α° with the horizontal center line of the stove burner when viewed from a plane, and has an angle of β° with the vertical center line of the stove burner when viewed from the side. This configuration allows the thermocouple element to be installed at an angle, thereby ensuring reliable operation of the thermocouple element and further improving safety.

電磁安全弁（図示せず）を励磁し開成維持する。 In FIG. 3, the thermocouple element 1 is
The mounting angle is α° (approximately 70° in this embodiment). Further, the mounting angle when viewed from the side in FIG. 4 is β° (approximately 60° in this embodiment) with respect to the vertical center line V of the stove burner 2. The heat-sensitive portion 1a of the thermocouple element 1 is located within the burner flame F. The stove burner 2 has a toothed portion forming a burner cap 4 and a burner flame opening 3, and is rotatably mounted with the wave-shaped toothed portion abutting against the upper opening of the burner body 5.
By having the above-mentioned mounting angle α°, no matter which position the burner cap 4 of the stove burner 2 rotates and is stopped, the entire heat-sensitive portion 1a remains in the inner flame Fb.
A part of it is always surrounded by a strong external flame without being enveloped by it, and a high thermoelectromotive force can be generated at all times. In addition, by having the mounting angle β°, the heat sensitive part 1a is always surrounded by the outer flame Fa of the burner flame F even when the length of the burner flame F changes (shortens) when the burner burner 2 is used with reduced firepower. As a result, a normal thermoelectromotive force is generated. This thermoelectromotive force excites an electromagnetic safety valve (not shown) in the gas circuit to keep it open.

時間が短い。(1) As mentioned above, there are 15 types of gases in Japan, each with a different flame length, but for complex combustion, the present invention allows all or part of the heat-sensitive part of the thermocouple element to be kept in the flame at all times. Since it is located in the outer flame (high temperature part), a high thermoelectromotive force can be obtained, and the adsorption retention time is short.
