【発明の詳細な説明】
本発明は、バーナの燃焼熱気を室内に放出して
室内暖房を行う室内開放型の暖房器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an indoor open type heater that heats the room by releasing hot air from a burner into the room.
従来から知られている開放型暖房器はバーナと
してブンゼン式バーナを使用したもので、２次空
気を必要とし２次空気との接触による外炎での高
温燃焼反応でNO2の生成が促進され室内空気が汚
染されるという不都合を有している。 Conventionally known open type heaters use a Bunsen burner as a burner, and require secondary air, which promotes the production of NO 2 through a high-temperature combustion reaction in the external flame due to contact with the secondary air. This has the disadvantage that indoor air is contaminated.

FIG. 1 is a cutaway front view of an example of the embodiment of the present invention. Reference numeral 1 denotes an outer casing of the heater, and inside the outer casing 1 there is a primary air combustion type burner 2,
A hot air duct 3 that is airtightly connected to the burner 2 and extends downward is housed therein, and a heat dissipation fin A is disposed on the side of the hot air duct 3.

る。 From the exhaust port 3a at the lower end of the hot air duct 3 to the outer casing 1
The hot combustion air is released into the room through the exhaust window 1a on the lower front side of the engine. A circulation fan 4 for circulating and blowing indoor air is provided in the upper part of the outer casing 1.
While cooling the hot air duct 3 with the indoor air taken in from the back of the outer casing 1, the combustion hot air from the exhaust port 3a and the indoor air heat-exchanged in the hot air duct 3 are mixed and discharged from the discharge window 1a. The orientation of the burner 2 is not limited to the downward arrangement with the combustion surface 2a facing downward as shown in FIGS. 1 and 2, but can also be arranged horizontally as shown in FIG. 3. FIG. 4 is a cross-sectional side view showing an example in which the radiation fins A are vertically arranged in parallel.
ここで本発明の動作を説明すれば、全１次空気

そこで本発明はダクト３内の燃焼熱をダクト外部

３ａに於いては燃焼熱気の温度は低下するので、
これを例えば、100〜200℃程度の熱気として放出
すれば、循環フアン４による室内循環空気と混合
して、暖房熱気に適した温風温度が得られる。 To explain the operation of the present invention, primary air is forcibly supplied to the all-primary air combustion type burner 2, and the primary air excess ratio is increased to further reduce the generation of NO 2 . I tried to lower it. In other words, compared to Bunsen burners, all primary air combustion burners have a smaller contact area between the flame and the atmosphere, resulting in lower NO 2 generation, but since the excess air ratio has been increased, excess primary air in the combustion flame is reduced. reduces the temperature of the flame by absorbing the combustion reaction heat, and furthermore, the hot air duct 3 airtightly connected to the burner 2 cuts off contact with the outside air, reducing the generation of NO 2 . However, since the hot air duct 3 was airtightly connected to the burner 2, the temperature inside the duct significantly increased, and there was a limit to the decrease in NO 2 .
Therefore, the present invention actively dissipates the combustion heat inside the duct 3 from the outside surface of the duct, thereby reducing the internal combustion reaction heat by lowering the duct internal temperature, thereby preventing the generation of NO 2 . In addition, since the temperature of the combustion hot air decreases at the duct tip opening 3a,
For example, if this is released as hot air of about 100 to 200°C, it will be mixed with indoor circulating air by the circulation fan 4 to obtain a hot air temperature suitable for heating hot air.

として使用出来る効果を有する。 As described above, according to the present invention, the hot air duct that is airtightly connected to the primary air combustion type burner is cooled from the outside by the circulation fan, so that the temperature inside the duct is lowered and the combustion flame temperature can be lowered. The amount of NO 2 generated is extremely low, making it possible to use it as a safe heater.
