【考案の詳細な説明】
この考案は一般室内の天井等に設ける火災感知器の改良
に関するものである。[Detailed description of the invention] This invention relates to an improvement of a fire detector installed on the ceiling of a general room.
その目的とするところは微少な温度上昇によって電気接
点が閉じるようにすることである。The purpose is to cause the electrical contacts to close due to a slight increase in temperature.
他の目的は空気箱を取付枠に対して簡単にしかも気密に
取付けられるようにすることである。Another purpose is to allow the air box to be easily and airtightly mounted to the mounting frame.
父、他の目的は空気相自体の持つ熱をダイヤフラムの枠
体等に伝導しないようにすることである。Another purpose is to prevent the heat of the air phase itself from being conducted to the diaphragm frame, etc.
この考案を添付図面によって説明すると、次の通りであ
る。This invention will be explained with reference to the accompanying drawings as follows.
有底円筒形空気箱１の上端縁に外向きの鍔１′を形成し
、該鍔１′を合成樹脂製環状取付枠２の円筒形内面２′
内に鋳込んで一体的に形成し、又取付枠２の上面にダイ
ヤフラム５の枠体３を設け、該枠体３と前記鍔１′との
間に、前記合成樹脂製環状取付枠２の一部分を介入グさ
せ、前記ダイヤフラム５の上部に電気接点６を設けた火
災感知器である。An outward facing flange 1' is formed on the upper edge of the bottomed cylindrical air box 1, and the flange 1' is attached to the cylindrical inner surface 2' of the synthetic resin annular mounting frame 2.
A frame 3 of a diaphragm 5 is provided on the upper surface of the mounting frame 2, and a frame 3 of the synthetic resin annular mounting frame 2 is provided between the frame 3 and the flange 1'. This is a fire detector in which a part of the diaphragm 5 is interposed and an electrical contact 6 is provided on the upper part of the diaphragm 5.
なお、４は前記枠体３の孔、７は上蓋、８はフリノジで
あり、その両端をダイヤフラム５の枠体３の上方にビス
９で取付け、中央部で前述の電気接点６を支持している
。In addition, 4 is a hole in the frame 3, 7 is an upper cover, and 8 is a fringe, whose both ends are attached to the upper part of the frame 3 of the diaphragm 5 with screws 9, and the above-mentioned electrical contact 6 is supported at the center. There is.
１０は該電気接点を上下に調節するための調節ねじ、１
１．１２はリード線である。10 is an adjustment screw for adjusting the electric contact up and down;
1.12 is a lead wire.
この考案は上述のような構造であり、蓋体７を室内の天
井等にとりつけて釦き、常時はダイヤフラム５の上面と
電気接点６との間が開いて釦り、これによりリード線１
１と他のリード線１２との間に電気が流れないようにな
っている。This device has the above-mentioned structure, and the lid body 7 is attached to the ceiling of the room and pressed, and the button is normally opened between the top surface of the diaphragm 5 and the electrical contact 6, and this allows the lead wire 1
1 and other lead wires 12 so that no electricity flows between them.
火災が発生し、空気箱１が加熱されると、その中の空気
も温度上昇し、その圧力が上昇しダイヤフラム５を押し
上げ、これとその可動範囲にある電気接点６とが電気的
に閉じてリード線１１と他のリード線１２との間に電流
が流れ、図示されていないが、これらに接続されている
報知器を作動するものである。When a fire occurs and the air box 1 is heated, the temperature of the air inside it also rises, and its pressure rises, pushing up the diaphragm 5, which electrically closes the diaphragm 5 and the electrical contacts 6 within its movable range. A current flows between the lead wire 11 and the other lead wire 12, and although not shown, it operates an alarm connected to these wires.
この際二本案は特に空気箱１の上端縁に外向きの鍔１′
を形成し、この部分を取付枠２の内面２′に鋳込んだの
で、従来のようにビスとパツキンで取付ける場合と比較
して取付は操作が極めて簡便であり、かつ又、この部分
の締付不良による空気のもれをなくし、作動不良を起す
おそれがない。In this case, the two proposals are particularly designed with an outward facing flange 1' on the upper edge of the air box 1.
Since this part is cast into the inner surface 2' of the mounting frame 2, the installation operation is extremely simple compared to the conventional installation using screws and gaskets, and the tightening of this part is extremely simple. Eliminates air leaks due to poor attachment, and there is no risk of malfunction.
又、前記鍔１′を合成樹脂製の取付枠２に鋳込んで形成
したことにより、鍔１′の上にかつ鍔１′と枠体３との
間に、合成樹脂製取付枠２と一体的に形成された介入部
ブを形成することができ、従って空気箱１と前記枠体３
を熱的に絶縁することができる。Furthermore, since the flange 1' is formed by being cast into the synthetic resin mounting frame 2, the flange 1' is integrally formed with the synthetic resin mounting frame 2 on the flange 1' and between the flange 1' and the frame 3. The air box 1 and the frame 3
can be thermally insulated.
このため火災発生の際に空気箱１内の温度が上昇した場
合、その熱がダイヤフラム５の枠体３及びこれと接触す
るブリッジ８等の熱容量の犬きい部分に伝導して所謂逃
ることを防止することができる。Therefore, when the temperature inside the air box 1 rises in the event of a fire, the heat is conducted to the parts with the lowest heat capacity, such as the frame 3 of the diaphragm 5 and the bridge 8 that come into contact with it, and is prevented from escaping. It can be prevented.
従って空気箱１の保有する熱エネルギーを効率良く利用
することができ、敏感な火災感知器を得ることかできる
。Therefore, the thermal energy possessed by the air box 1 can be used efficiently, and a sensitive fire detector can be obtained.
