されている。(Problems to be solved by the invention) By the way, although the air conditioner is designed to withstand use for a period of about 10 years, if it is used continuously beyond this service life, The relative inferior durability of electrical system components is a problem. That is, since the mechanical parts constituting the refrigeration cycle still have sufficient durability, it is possible to continue to use the air conditioner beyond its service life. On the other hand, the electrical parts of the electrical parts box are inferior in durability to the mechanical parts, so if the air conditioner continues to be used beyond the service life without maintenance such as inspection and replacement of parts, Since the insulation deteriorates further from parts with low durability, safety measures to prevent electric fires have become an issue in consideration of the case of being used as it is.
そこで、本考案は、上記従来技術の有する問題点を解消

The present invention is characterized in that an extinguishing agent container in which a extinguishing agent is enclosed is provided inside the main body, and is made of a resin having a relatively low melting point. The extinguishant container may be provided inside the main body or inside the electrical component box.

防止される。(Operation) When fire occurs due to deterioration of the insulation of the insulator inside the electrical parts box, the heat extinguishes the extinguishant container inside the body of the air conditioner, and the extinguishing agent contained in the container extinguishes the ignition area. So it will be extinguished automatically. Further, since the power supply circuit is cut off before the extinguishant container starts to melt, it is possible to prevent the fire from re-igniting after it has spread and once it has been extinguished.
（実施例） 以下、本考案による空気調和機の一実施例について添付
の図面を参照して説明する。Embodiment An embodiment of the air conditioner according to the present invention will be described below with reference to the accompanying drawings.
第３図において、符合１は、空気調和機の室内機の本体

に電気部品箱６が着脱自在に収納されている。An engagement hole 4 having a rectangular shape and having a size into which a finger can be inserted is formed on the upper surface of the side plate 3 on one side of the main body 1. A pair of guide ribs 5 and 5 extending downward from the side plate 3 are formed on both sides of the engagement hole 4, and are surrounded by the side plate 3 and the guide ribs 5 and 5, and the upper portion inside the main body 1 is surrounded. The electric component box 6 is detachably accommodated in the accommodating portion at a position corresponding to.

It is adapted to be elastically engaged through the fitting hole 4.
次に、第１図は、このような電気部品箱の内部を表わし

機、ファンの送風機と接続されている。In FIG. 1, reference numeral 8 indicates a case of the electric component box. A printed wiring board 9 is fixed to the inner side surface of the case 8, and a relay 10 which constitutes a power supply circuit is incorporated in the printed wiring board 9. As shown in FIG. 2, the power source 11 is connected via a relay 10 to the compressor of the outdoor unit 12 and the fan blower.
また、電気部品箱６のケース８内側の天井面には、筐体

そして、消火剤容器13の内部には、化学系の消火剤が封
入されている。A casing-shaped extinguishant container 13 is fixed to the ceiling surface inside the case 8 of the electric component box 6. This extinguisher container 13
Is molded from a low melting point synthetic resin that melts at a relatively low temperature.
A material that melts at a temperature of about 100 ° C is selected.
A chemical extinguishant is enclosed in the extinguishant container 13.

点をOFFにする作動信号を出力するようになっている。Next, such a digestive agent container 13 is provided with a temperature detector 14 for detecting the surface temperature thereof, and in FIG. 2, the temperature signal output from the temperature detector 14 is introduced into the control circuit 15. . The control circuit 15 compares this temperature signal with a preset temperature stored in advance, that is, a temperature close to the melting point of the material of the extinguishant container 12 described above (95 ° C. in this embodiment), and digests it. When it is determined that the surface temperature of the agent container 13 has approached the melting point higher than this set temperature, an operation signal for turning off the contact of the relay 10 is output.

８の内部にあって天井面に固定されているので、中に封
入されている消火剤がこの消化剤容器13下方に飛散する
結果、発火部位は直ちに消火される。Then, in the electrical component box 6 configured as described above, when the insulation of the insulator of the printed wiring board 9 deteriorates and ignition occurs due to discharge, the surface temperature of the extinguishant container 13 rises. . This rise in surface temperature is due to the extinguishant container
When the melting point of the material of 13 is exceeded, the material of the digestive agent container 13 melts. In this case, since the extinguishant container 13 is fixed inside the case 8 of the electric component box 6 and fixed to the ceiling surface, the extinguishant contained therein scatters below the extinguishant container 13, resulting in ignition. The part is extinguished immediately.
一方、上記のようにしてプリント配線基板９の発火部位
が一旦消火された場合でも、室外機12の圧縮機、ファン
の電動機が運転したままであると、再び発火する虞があ
る。On the other hand, even if the ignition part of the printed wiring board 9 is once extinguished as described above, if the compressor of the outdoor unit 12 and the electric motor of the fan are still operating, there is a risk of ignition again.
しかしながら、消化剤容器13が融け出し始める融点に近

火するようなことが防止される。However, when the surface temperature of the extinguishant container 13 rises to 95 ° C., which is close to the melting point where the extinguishant container 13 begins to melt, the contact of the relay 10 is already turned off in response to the operation signal output from the control circuit 15. . Therefore, since the connection between the power supply circuit and the outdoor unit 12 is cut off, the printed wiring board 9 is not discharged and the spread of fire is prevented, and the ignition part of the printed wiring board 9 is extinguished once as described above. After that, it is prevented from re-igniting.

れ、電気火災に対する安全信頼性が著しく向上する。As is clear from the above description, according to the present invention, a fire extinguisher made of a resin having a relatively low melting point is used in the inside of the main body of the air conditioner, such as the inside upper part of the air conditioner or the inside of the electric component box. Since a fire extinguisher container filled with is attached, the electric parts inside the electric parts box will be discharged, and even if a fire occurs, the fire extinguishing agent will extinguish the fire before it becomes an electric fire, ensuring safety and reliability against electric fires. Is significantly improved.
