By the way, in recent years, it has been desired to make the warm air heater as described above compact, but in order to make it compact, the combustion cylinder and the convection blower must be brought close to each other, so that the convection blower is required. There was a problem that the rotating shaft of the above became abnormally high temperature due to the heat effect of the combustion cylinder, the lubricating oil of the bearing portion was evaporated or hardened, and the rotating shaft did not rotate smoothly. Therefore, conventionally, a protective plate is hung from the rear edge of the heat shield plate to cover the front of the convection blower so that the rotating shaft does not have an abnormally high temperature. However, if the front side of the convection blower is covered with this protective plate, fresh air cannot be introduced into the open part of the combustion cylinder, and the air supply amount of the combustion blower is insufficient due to filter clogging, etc. The flame of No. 6 becomes a red flame and extends for a long time, and if that flame flows out from the open part of the combustion cylinder, it is not possible to shorten the flame, and the flame goes out from the hot air outlet,
There is a problem that the amount of carbon monoxide generated increases.

According to the present invention, the rotating shaft is not overheated by the radiant heat from the combustion cylinder, the temperature rise of the rotating shaft can be suppressed, and the harmful effect due to the temperature rise of the rotating shaft is eliminated. it can. Also, even if the air supply becomes insufficient due to filter clogging, the flame of the burner becomes red fire, and it extends for a long time and flows out from the open part of the combustion tube, the air flow distribution plate acts to blow air from the convection blower. Since air is distributed and sent between the open part of the combustion tube and the heat shield and between the heat shield and the wind tunnel top, the outflowing flame is shortened with fresh air.
In addition to being able to prevent the flame from going out from the hot air outlet, it is also possible to suppress the sudden increase in carbon monoxide that occurs when the air supply is insufficient and to perform stable combustion, and also to prevent the body case from overheating. . In addition, it is necessary to suppress the temperature rise of the rotating shaft.

Is between the upper end of the open part of the combustion cylinder and the lower end of the air flow distribution plate.
Away from the combustion chamber, the amount of air blown to the opening of the combustion tube is reduced.
It is not preferable because it is too much. Conversely, when L2 exceeds 2.5
The propeller fan is connected to the upper end of the open part of the combustion cylinder and the air flow distribution plate.
Since it approaches the lower end, the amount of air blown to the opening of the combustion tube
Too many. If L3 is less than 3.0, heat shield and wind tunnel top
The amount of air blown between the two parts increases, and the air is blown to the opening of the combustion tube.
The quantity is reduced. Heat shield and wind tunnel when L3 exceeds 4.0
The amount of air blown between the tops is reduced, causing the body case to overheat.

By the way, the suction port 5R of the blower 5D for combustion
If a filter (not shown) provided in the fuel cell is clogged or clogged by a curtain or the like, the supply amount of the combustion primary air into the vaporization cylinder 5A decreases, and the supply air is insufficient. At this time, the flame F formed on the burner head 5B becomes a red flame, which extends for a long time like the flame FX shown by the phantom line in FIG. 1 and flows out from the upper opening 7 of the combustion cylinder 6, but from the convection blower 3. Since a part of the blown air is introduced into the space between the upper opening 7 of the combustion cylinder 6 and the heat shield plate 10 through the ventilation hole 12 by the action of the air volume distribution plate 11, the upper opening 7
Fresh air is supplied at a right angle to the outflowing flame FX, and this fresh air accelerates combustion of the flame FX to shorten the flame, and the flame does not come out from the hot air outlet 2. Further, since the combustion of carbon monoxide in the flame FX is promoted to become carbon dioxide, the generation of carbon monoxide can be reduced.
