家庭の食卓で気軽に使用することができるため厳しい検査を受けるカ セットコンロにおいては、ガスボンベの装填上の注意やガスボンベからのガスが コンロ内での漏れを防止すること、または使用上の不注意による異常なガス圧に よる事故の防止など種々の安全手段が考えられている。 For cassette hobs that are subject to strict inspection because they can be used easily at the table at home, be careful when loading the gas cylinder, prevent gas from leaking from the gas cylinder inside the stove, or be careful when using it. Various safety measures are considered, such as prevention of accidents due to abnormal gas pressure.
【0003】 しかし、ボンベ装填上の注意や使用上の注意などは添付してある注意 書を読めば理解できるがボンベからの異常なガス圧に対しての処理には対応する ことができず爆発事故の発生原因となっている。However, although the precautions for loading and using the cylinder can be understood by reading the attached cautionary note, it is not possible to deal with processing against abnormal gas pressure from the cylinder and it explodes. It is the cause of the accident.

考案者は、カセットコンロの事故を未然に防止するため鋭意研究を重ねた 結果本考案に到達したものであって、カバナー内のガス通路に弓形に形成された 板バネに支持された閉止弁を設け、これに封止用のOリングを付設して異常なガ ス圧が発生した場合に板バネが作動して閉止弁を移動させOリングによって自動 的にガス通路を遮断して事故の発生を未然に防止する安全装置を提供するもので ある。 The inventor arrived at the present invention as a result of earnest research to prevent accidents on the cassette stove, and achieved the present invention. An O-ring for sealing is attached to this, and if an abnormal gas pressure is generated, the leaf spring operates to move the stop valve and the O-ring automatically shuts off the gas passage to cause an accident. It is to provide a safety device to prevent the above.

添付図面により本考案の実施の形態を説明すると、図1はカセットコンロ の一部を割裁した平面図であり、本考案の要部であるガバナー(2)とボンベ( 3)の位置関係を示している。図2はガバナー(2)内での本考案の安全装置の 構成を示す詳細図である。 An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view in which a part of a cassette stove is cut, and shows a positional relationship between a governor (2) and a cylinder (3) which is an essential part of the present invention. Shows. FIG. 2 is a detailed view showing the structure of the safety device of the present invention in the governor (2).

ガスボンベ内のガス圧は通常2kg/cm2に定められている。ガスボン ベ(5)を装填するとガスはガバナー(4)内のAから入り支持バネ(2)に支 承されている閉止弁Fを作動することなくBへ流れて炎口(1)に向って着火さ れるもので通常の燃焼が行われる。The gas pressure in the gas cylinder is usually set to 2 kg / cm 2 . When the gas cylinder (5) is loaded, the gas enters from A in the governor (4) and flows to B without operating the stop valve F supported by the support spring (2) toward the flame port (1). It is ignited and normally burned.
【0007】 しかし、コンロの操作を誤ってコンロ内が過熱してボンベ内のガス圧が異 常に上昇したとき(例えば4kg/cm2〜6kg/cm2)は閉止弁Fは、支 持バネ(2)に抗して矢印方向に押され板バネCを反転させる。However, when the stove is erroneously operated and the stove is overheated and the gas pressure in the cylinder rises abnormally (for example, 4 kg / cm 2 to 6 kg / cm 2 ), the stop valve F is provided with a supporting spring ( It is pushed in the direction of the arrow against 2) to reverse the leaf spring C.
【0008】 このような状態になると閉止弁Fに設けてあるOリング(3)が通路内壁 の段部D位置に当接し通路を遮断することによってガスの流れは止まりガスは炎 口(1)に達することなく安全装置が作動する。In such a state, the O-ring (3) provided on the shutoff valve F comes into contact with the step D position of the inner wall of the passage to cut off the passage, whereby the gas flow is stopped and the gas is discharged from the flame port (1). The safety device operates without reaching.
【0009】 しかして、この安全装置を解除する場合は異常なガス圧のボンベを取 外して正常のガス圧のボンベ(5)と交換し、リセット片Gを矢印方向に押して 板バネCを元の位置に押し返すことによって作動していた安全装置は解除されて 通常の使用に戻るものである。図中の符号(6)は着火ツマミを示している。When the safety device is released, however, the cylinder with an abnormal gas pressure is removed and replaced with a cylinder with a normal gas pressure (5), and the reset piece G is pushed in the direction of the arrow so that the leaf spring C is removed. The safety device that was activated by pushing it back to the position will be released and it will return to normal use. Reference numeral (6) in the drawing indicates an ignition knob.

本考案は前記のようにボンベ内のガス圧が異常に上昇した際に閉止弁 Fが作動してガスの流れを自動的に遮断して火を止め、ボンベの爆発を防止する ことができるものでカセットコンロの安全装置としてきわめて簡単な構造で、し かも確実に作動する。そして、この作動している安全装置の解除も容易であって 、従来からのこの種の安全装置に比較して画期的な使用上の作用効果を奏する。 According to the present invention, when the gas pressure in the cylinder rises abnormally as described above, the stop valve F operates to automatically shut off the gas flow to stop the fire and prevent the cylinder from exploding. As a safety device for a cassette stove, it has an extremely simple structure and operates reliably. Further, it is easy to release the operating safety device, and has an epoch-making operational effect as compared with the conventional safety device of this type.
