が消えた場合の確認が必要となる。BACKGROUND TECHNOLOGY A conventional gas stove is a gas cooking appliance that is frequently used in general households, and the gas is turned on and off many times. For this reason, it is necessary to check whether the flame has ignited and extinguished it, or if the flame has been extinguished by blowing out.

を絞つた時は吹消えた場合に危険であつた。Problems that the invention aims to solve However, the pots that are heated come in a variety of shapes and sizes, and in particular when using a large pot, the gas flame becomes invisible and it is difficult to confirm whether or not the fire is actually burning. I couldn't do it at first glance. Furthermore, in a brightly lit kitchen, it was sometimes difficult to see the flames even if they were burning, and this was especially dangerous if the flames were to be extinguished when the flames were turned down.

を表示する構成とした。Means for Solving the Problems In order to solve the above problems, the gas stove of the present invention includes a detection section that is arranged to be heated by the flame of the gas burner, detects combustion of the gas burner, and an operation of the detection section. The sensing part is made of a shape memory alloy formed into a tension spring shape that contracts when heated, and the notification part is configured to detect whether or not the burner is burning due to the contraction of the shape memory alloy. The system is designed to display that the fuel is being burned.

火が燃えているか消えているか確認可能となる。 As shown in FIG. 2, the detection section 9 made of a shape memory alloy has one end fixedly held on a rod 11 and the other end attached to an arm 13 rotatably attached to a fulcrum 12. The other end of the arm 13 is loosely attached to a display board 15 via an elongated hole 14.
The detection part 9 is arranged so as to be heated by the flame 10 of the burner 2, and the length L is short when it is heated as shown in the figure. As a result, the arm 13 becomes the fulcrum 1
2 and pull down the display board 15 downward.
At this time, a portion 16 of the display board 15 corresponding to the display window is colored (for example, red) to indicate that the flame is burning (see FIG. 3A). Next, burner 2
When the flame 10 is extinguished, the temperature is low, so the length L of the detection part 9 becomes longer, the display board 15 is pushed up as shown by the broken line in FIG. 2, and the portion 17 corresponding to the display window 7 is colored. The displayed color (for example, black) indicates that the fire is not burning (see Figure 3B). With the above, it is possible to check whether the fire is burning or extinguished just by looking at the display window without checking the fire.

れる。 FIG. 4 shows another embodiment in which an arm 13' rotating about a fulcrum 12 is rotated by displacement of a sensing portion 9 made of a shape memory alloy, similar to FIG. 2. The arm 13' has an electrical contact 18, and a contact 19 is arranged opposite to the electrical contact 18. When the detection part 9 is heated by the burner 10 and the length L becomes short, the contact 1
8 is connected to the contact 19 and the contact 18 is connected to the power supply 20.
19 and the current limiting resistor 21, the light emitting diode 22 is powered to light up. When there is no flame, since L is long, the contacts 18 and 19 are separated and the light emitting diode 22 is turned off. As described above, display can be performed simply by replacing the display window 7 in FIG. 1 with the light emitting diode 22. Here, the light emitting diode 22
However, a normal filament lamp may be used, or a neon lamp may be lit by using an alternating current power source 20. Furthermore, in addition to lamps, it is also easily possible to notify by a sound such as a buzzer or a bell.
形状記憶合金の形状も第２図，第４図に示す方
法以外のものでもよく、また表示板１５やアーム
１３の形状も種々考えられる。 The shape of the shape memory alloy may be other than those shown in FIGS. 2 and 4, and various shapes of the display plate 15 and the arm 13 are also conceivable.
さらにこれ等報知信号により火炎が失火した時
にガスを自動的に停止する安全弁を駆動すること
も容易に考えられる。 Furthermore, it is easily possible to use these notification signals to drive a safety valve that automatically shuts off the gas when the flame misfires.
発明の効果
以上に説明したように本発明のガスコンロは、
次のような効果を有する。Effects of the Invention As explained above, the gas stove of the present invention has
It has the following effects.
(1) 燃焼の有無を表示窓あるいはランプまたは音
により報知する構成であるために、炎を見なく
てもバーナの着火、消火の確認が容易にでき
る。このためにガスコンロ上に大きな鍋を置い
た場合や、火力を絞つたとき、あるいは周囲が
明るい場合などの炎が目で確認しにくい場合で
も一目で判別できる。(1) Since the burner is configured to notify the presence or absence of combustion through a display window, lamp, or sound, it is easy to confirm whether the burner is ignited or extinguished without looking at the flame. This makes it possible to identify the flame at a glance even when the flame is difficult to see, such as when a large pot is placed on the gas stove, when the flame is turned down, or when the surrounding area is bright.
(2) ふきこぼれや吹き消えによるバーナの失火も
報知可能であり、安全で安心して調理できる。(2) It is also possible to notify you of burner misfires due to boiling over or blowing out, allowing you to cook safely and with peace of mind.
(3) 検知部に形状記憶合金を使用しているため
に、従来のバイメタルなどに比べて、応答が速
くまた変位が大きい。このためにバーナが着火
や失火してから報知部が動作するまでの時間が
短く待ち時間がなく使い勝手がよい上に、変位
が大きいので報知部の形状を大きくすることが
可能となり、遠くからの確認が容易にできる。(3) Since a shape memory alloy is used in the sensing part, the response is faster and the displacement is larger than that of conventional bimetals. As a result, the time from when the burner ignites or misfires to when the alarm unit operates is short and there is no waiting time, making it easy to use.In addition, since the displacement is large, the shape of the alarm unit can be enlarged, making it possible to detect it from a distance. Confirmation is easy.
(4) 形状記憶合金を、加熱により収縮する構成の
引つ張りスプリング状に成形することにより、
もし検知部の断線などの異常が発生しても点火
表示しない方向に破損し、安全側に動作する。(4) By forming the shape memory alloy into a tension spring that contracts when heated,
If an abnormality occurs such as a disconnection of the detection part, it will be damaged in a direction that does not indicate ignition, and it will operate safely.
