Description

【発明の詳細な説明】産業上の利用分野本発明は、家庭用の暖房、給湯等に使用される燃焼装置
に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a combustion device used for home heating, hot water supply, etc.

従来の技術従来のこの種の燃焼器は、第３図に示すように有底筒状
の燃焼筒１に気化筒２を立設し、この気化筒２の壁面に
設けられた複数の空気噴出孔３からの旋回流により燃焼
を行なうよう構成されていた。BACKGROUND ART As shown in FIG. 3, a conventional combustor of this type includes a combustion tube 1 having a bottomed cylindrical shape and a vaporization tube 2 erected thereon, and a plurality of air jets provided on the wall of the vaporization tube 2. It was configured to perform combustion by swirling flow from the hole 3.

発明が解決しようとする問題点しかしながら上記のような構成では下記の問題点を有し
ていた。Problems to be Solved by the Invention However, the above configuration has the following problems.

（１）特に燃焼量を変化させた場合、燃焼筒内部での火
炎形成が均一とならず内底面に油溜りが生じ。(1) Especially when the combustion amount is changed, the flame formation inside the combustion cylinder is not uniform and oil pools occur on the inner bottom surface.

燃焼が不安定となる。Combustion becomes unstable.

交）また、内底面に油溜りが生じると燃焼停止時に白煙
が発生したシ、悪臭が畏時間残る。Also, if an oil pool forms on the inner bottom surface, white smoke will be generated when combustion stops, and a foul odor will remain for a long time.

本発明はかかる従来の問題点を解消するもので、燃焼筒
の内底面の温度を均一化することによシ油溜りを防止し
、また燃料の完全蒸発化を目的とする。The present invention is intended to solve these conventional problems, and aims to prevent oil accumulation by equalizing the temperature of the inner bottom surface of the combustion cylinder, and to completely evaporate the fuel.

問題点を解決するための手段上記問題点を解決するために本発明の燃焼器は。Means to solve problems The combustor of the present invention solves the above problems.

燃焼筒の内底面にヒートパイプを配設するという構成を
備えたものである。It has a structure in which a heat pipe is disposed on the inner bottom surface of the combustion cylinder.

作　　　用本発明は上記した構成によって、燃焼量が変化し、燃焼
筒内部での火炎形成が不均一となっても。Effects The present invention has the above-described configuration, so that even if the combustion amount changes and the flame formation inside the combustion cylinder becomes non-uniform.

ヒートパイプの熱伝導により内底面の温度は均一化され
低温部ができないため油溜りが生じず燃焼は安定化する
。また燃焼停止時の白煙、悪臭も発生しない。The heat conduction of the heat pipe equalizes the temperature of the inner bottom surface, eliminating the formation of low-temperature areas, resulting in no oil pools and stable combustion. Also, no white smoke or bad odor is generated when combustion stops.

実施例以下、本発明の一実施例を第１図、第２図を用いて説明
する。EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2.

第１図、第２図において、１は有底筒状の燃焼筒、１ａ
は内底面、２は燃焼筒の内底面略中央に立設した気化筒
、３は気化筒２の壁面に設けられた複数の空気噴出孔、
４は電化筒の上端面よシ低い位置に開孔された燃料噴出
ノズル、５はヒートパイプ、６は点火プラグ、７は給油
ポンプ、８は送風ファン′、９はバーナリン′グである
。In Figures 1 and 2, 1 is a cylindrical combustion tube with a bottom, 1a
is an inner bottom surface, 2 is a carburetor tube installed approximately at the center of the inner bottom surface of the combustion tube, 3 is a plurality of air jet holes provided on the wall surface of the vaporizer tube 2,
4 is a fuel injection nozzle opened at a position lower than the upper end surface of the electrification tube, 5 is a heat pipe, 6 is a spark plug, 7 is a fuel pump, 8 is a blower fan', and 9 is a burner ring'.

上記構成において、燃料がノズ／Ｌ／４から燃焼筒１内
に噴出されると、送風ファン８から気化筒２に圧送され
るとともに空気噴出孔３から旋回噴出した空電と燃料が
混合される。点火プラグ６により石火され燃焼を開始す
る。In the above configuration, when fuel is injected into the combustion tube 1 from the nozzle/L/4, it is forced into the vaporization tube 2 from the blower fan 8, and the fuel is mixed with static electricity that is swirled and ejected from the air injection hole 3. . The spark plug 6 ignites the spark and starts combustion.

発明の効果以上のように本発明の燃焼器によれば次の効果が得られ
る。Effects of the Invention As described above, the combustor of the present invention provides the following effects.

（１）燃焼量を変化させた場合でも、・９ζ焼筒内展而
面度の不均一化は生じず常に高温が保たれるため、内底
面に油溜りが生じず燃焼が安定する。(1) Even when the combustion amount is changed, the degree of expansion inside the 9ζ combustion cylinder does not become uneven and the high temperature is always maintained, so that no oil pools occur on the inner bottom surface and combustion is stable.

（２）まだ、内底面に油溜シが生じないため燃焼停止時
に発生していた白煙、悪臭が解消する。(2) Since no oil sump is formed on the inner bottom surface, the white smoke and bad odor that occur when combustion stops are eliminated.
