As disclosed in Japanese Patent Publication No. 201951, consideration is given to the partition of burner flame holes and the introduction method of secondary air so that the stability of combustion can be ensured even if the difference in heat generation amount between strong combustion and weak combustion is large. There is something I did.

れている。FIG. 3 is a cross-sectional view showing an example of a conventional combustion apparatus for a hot air heater. In the figure, a mixed gas of vaporized gas and primary air is sent to a burner 21, and after being mixed therein, It burns in the flame hole 22. The combustion chamber 23 and the air chamber 24 are vertically divided by the partition plate 25 at the flame hole 22 position.

9 rises along the line 9 and is guided to the combustion chamber 23 through the discharge opening 30 provided in the upper part of the front surface of the baffle plate 29, and acts on the combustion flame. The combustion exhaust gas is discharged to the outside of the combustion chamber 23 through the opening 31 at the upper portion of the combustion chamber 23 due to the draft effect of the blower 28.
The hot air is mixed with the air blown from the blower 28 and is discharged into the room from the louver 32.

燃焼や一酸化炭素ＣＯの発生が抑制される。By positioning the discharge opening 30 of the baffle plate 29 below the height of the combustion flame 33 in the combustion chamber 23 during strong combustion, the secondary air 26 introduced into the combustion chamber 23 from the discharge opening 30 is removed. The combustion flame 33 at the time of strong combustion is mixed at right angles, a secondary air wall 34 is formed on the combustion flame 33 at the time of strong combustion, and secondary combustion occurs at this position.
Even if the primary air is insufficient, the secondary air is sufficiently supplied, and the red fire combustion and the generation of carbon monoxide CO are suppressed.

Stable combustion can be obtained without adversely affecting the combustion flame 35.

Since the secondary air is not secured, for example, the combustion flame 33 at the time of strong combustion comes into contact with the front side of the combustion chamber 23 to be cooled, and carbon monoxide CO and soot are generated, or the front side of the combustion chamber 23. However, there is a drawback that it causes a problem of abnormal heating.

形成する。When the warm air heater is turned on, the vaporizer 13
When the vaporizer 13 reaches the vaporization temperature, the pump 15 is electrified. The fuel supplied from the pump 15 is vaporized by the vaporizer 13, and the vaporized gas is ejected from the nozzle 14 into the burner 2. At this time, the jetting force from the nozzle 14 sucks the surrounding air from the primary air hole 3, and at the same time, a part of the air from the blower 10 is also pushed in from the primary air hole 3 as combustion air. The vaporized gas and the primary air are mixed by a mixing pipe (not shown) in the burner 2 and jetted from the flame hole 4 at the burner outlet to form a flame 9 in the combustion chamber 8.

また、燃焼室８の前面を過熱させることもない。The flame 9 formed on the flame hole 4 is cooled by the air from the secondary air hole 6 provided in the burner base 5, and when the combustion is weak, the flame 9 near the flame hole 4 is cooled by excess secondary air. Good combustion can be achieved without the generation of carbon monoxide. Further, in the case of strong combustion, the flame 9 near the flame hole 4 can perform the stable combustion, but at the upper part of the flame 9, only the secondary air from the secondary air hole 6 of the burner base 5 is insufficient. Secondary air behind the flame 9 is added from the secondary air opening 11 on the rear surface of the combustion chamber 8, and as secondary air in front of the flame 9, the secondary air inlet 12 on the side surface of the combustion chamber 8 is added.
By blowing air from above, the front surface of the flame 9 can be wrapped with the secondary air, so that the flame 9 does not come into contact with the front surface of the combustion chamber 8 and carbon monoxide is not generated, and complete combustion occurs.
Moreover, the front surface of the combustion chamber 8 is not overheated.

Since the opening area of the air holes is equivalent to the opening area of the primary air holes of the burner or smaller than the opening area of the primary air holes, and the secondary air inlet is also provided on the upper side of the combustion chamber, weak combustion is achieved. In the case of, it is possible to cool the flame with extra secondary air, or to perform good combustion without the generation of carbon monoxide without flicker, and in the case of strong combustion, the flame near the flame hole can be stably burned and the upper part of the flame In addition, the secondary air from the burner base secondary air holes is used to burn the shortage, the secondary air behind the flame is added from the secondary air opening on the rear surface of the combustion chamber, and it is burned as secondary air in front of the flame. Secondary air introduction on the side of the chamber The front of the flame can be wrapped with secondary air by blowing air from the front, the flame does not come into contact with the front of the combustion chamber, there is no generation of carbon monoxide or soot, and the front of the combustion chamber is completely burned. It has the effect of preventing abnormal heating.
