Problems to be Solved by the Invention However, in the above configuration, as shown in FIG. 4, since the convection fan 10 rotates counterclockwise, the generated wind tends to concentrate mainly at the lower right of the device body 13. Since it is difficult to flow to the lower left and left side of the main body, the temperature of the left side of the main body 13 increases, and there is a risk that the user will feel hot when touching the main body 13 with his/her hand. In addition, since the ignition device 8 is also located at the lower left of the appliance body 13, it is difficult for air to flow for cooling, and the temperature of the ignition device 8 increases over time, causing malfunctions and failures and shortening the lifespan of parts. I had a problem.

Furthermore, today, there is a high demand for high-temperature air and high radiation in heating appliances, so the above-mentioned problem is becoming more prominent. Instrument body 1
3, the outer surface of the instrument body 13 will become even hotter due to the radiant heat from the combustion tube 2, which will cause burns if the user's body comes into contact with the body. It was something.

The present invention is intended to solve the above problems, and aims to enable heating by hot air and radiation while lowering the temperature range of the entire main body, and to improve thermal efficiency by effectively utilizing the heat of the heat source. It is.

Means for Solving the Problems In order to solve the above problems, the heating combustor of the present invention has a partition plate that surrounds the rear outer periphery of the combustion tube and has a partition plate that intersects with the rotational direction of the convection fan to disperse the wind from the convection fan. The configuration includes an inclined plate that allows the

Operation The present invention has the above-described configuration, and the inclined plate disperses the air from the convection fan and allows the air to flow to every corner of the device body. This effectively cools the ignition system, etc.

EXAMPLE Hereinafter, a heating combustor according to an example of the present invention will be described with reference to FIGS. 1 to 3. In the figure, 20 is an instrument main body, and a burner 21 placed on a pedestal 22 is provided inside this instrument main body 20. A combustion tube 23 having a radiation window 23a is provided above the burner 21.
A heat exchanger 24 and an exhaust pipe 25 are provided at the upper part of the fuel cell 3. Further, a pump 26 for supplying fuel to the burner 21 is provided at the lower part of the device main body 20, and a pump 26 is provided to supply fuel to the burner 21.
The mixture is supplied to the mixing chamber 21a. Further, the burner 21 is supplied with air sent from the burner blower 1a27, which is branched into a primary air passage 28 and a secondary air passage 29.

An ignition device 30 is provided in the lower corner of the device main body 20, and a convection fan 31 for blowing warm air for heating is provided on the back of the device main body 20.

A radiation window 23a is provided on the side of the combustion tube 23, and air outlets 32 are provided at the front of the appliance main body 20 and located above, below, left and right of the radiation g23a. The combustion tube 23
The rear outer periphery of the convection fan 31 is surrounded by a partition plate 34, and an inclined plate 35 that intersects with the rotational direction of the convection fan 31 is attached to the rear surface of the partition plate 34. A control section 33 is disposed between the partition plate 34 and the side plate of the instrument main body 20.

The operation of the combustion appliance configured as described above will be explained below. First, the burner blower 27 is started and the pump 26 is operated. - Primary air is supplied from the primary air passage 28 to the mixing chamber 21a in the burner 21, and the pump 26
The fuel is sent to the mixing chamber 2]a. Mixing chamber 26
The fuel and primary air mixed in step a are ignited by the ignition bag 230, form a primary flame in the burner 21, mix with the secondary air passing through the secondary air passage 29, and burn in the combustion tube 23. Radiant heat is supplied to the front of the instrument main body 20 through 23a. The combustion gas flows from the combustion tube 23 to the heat exchanger 24, and is further discharged outside through the exhaust pipe 25. Further, a part of the air generated by the convection fan 31 hits the partition plate 34 and is swept downward. This downward wind is dispersed in the upward and left-right directions by the inclined plate 35, and the wind dispersed to the right flows along the outer periphery of the partition plate, preventing the control unit 33 and the right side of the instrument body 20 from becoming hot. It is discharged from the lower side of the air outlet 32. Next, the wind dispersed to the left is on the inclined plate 3.
5 to the left side of the instrument main body 20.

This prevents the temperature of the left side surface of the instrument body 20 from rising, and since the air is sent to the ignition device 30 located at the lower left of the instrument body 20, it is possible to prevent the temperature from becoming high. These winds are sent out from the lower side of the outlet 32 in the same way as the right side. In addition, the wind dispersed by the inclined plate 35 does not only flow in the left and right directions, but also rises by hitting the inclined plate 35, passes over the upper part of the partition plate 34, and passes through the combustion tube 2.
3 and into the outer wall of the heat exchanger 24. Heat is exchanged from the high-temperature combustion cylinder 23 and the outer wall of the heat exchanger 24 to generate warm air, which is then released into the air outlet 32 provided on both sides of the radiation window 23a.
More air is blown. In addition, the remaining wind generated by the convection fan 31 is transferred to the heat exchanger 24 and the combustion tube 23, which have reached a high temperature.
Since the hot air is sent directly to the outer wall of the radiant window 23a, the hot air is efficiently exchanged to become warm air, which is then blown through the air outlets 32 provided on both sides and above the radiation window 23a.

In this way, the wind flowing inside the appliance main body 20 can be directed to the combustion tube 23.
The heat exchange chamber S is surrounded by the rear outer periphery of the partition plate 34 and the partition plate 34.
