All of the warm air is discharged from the warm air outlet, and the amount of warm air can be increased, the heating performance by the warm air during the warm air heating operation is improved, and the radiant body heating air passage during the warm air heating operation is improved. Thus, the high-temperature gas leaks and the temperature of the radiator and its temperature rise can be prevented.

Further, the heating device according to the ninth aspect is configured such that the radiator is slanted so that the radiant energy generated by the radiator easily warms the front floor surface.

In the radiant heating operation in which the air flow switching means has switched the air flow from the blower to the radiant cooling air flow side, the radiant emits radiant energy so as to easily warm the front floor. Since it is inclined obliquely, the radiant energy radiated from the radiator warms the front floor surface of the device, which tends to be lower during the radiant heating operation, so that the front floor surface is improved and the radiator is improved. The high-temperature gas flowing upward along the surface becomes easy to follow the heat collecting surface, the heat collecting on the heat collecting surface is improved, and the amount of radiant energy generated from the radiator increases.

Further, the heating device according to the tenth aspect is configured such that the radiator is formed so as to protrude above the attached equipment housing, or to extend in the left and right directions or both directions.

Since the radiator is formed so as to protrude above, to the left or right of, or in both directions than the equipment housing to which the radiator is attached, the air path switching means directs the air flow from the blower to the radiator cooling air path side. At the time of the switched radiant heating operation, it is possible to prevent the high-temperature gas flowing upward along the radiator from being sucked by the airflow sucked into the blower of the device and causing a short circuit.

In the heating device according to the eleventh aspect, when the air flow from the blower is switched to the radiator cooling air passage side, a part of the air from the blower is heated through the lower side wall of the high-temperature gas generating means. It has a configuration in which a communication port that discharges from the wind outlet is provided.

In the radiant heating operation in which the air flow switching means switches the air flow from the blower to the radiator cooling air flow side, a part of the air from the blower is transferred to the hot air through the lower side wall of the high-temperature gas generating means. A process in which a part of the air from the blower flows through the lower side wall of the high-temperature gas generating means on the front floor of the device, which is likely to be low during the radiant heating operation, since the communication port for discharging from the outlet is provided. Then, the heat is exchanged to generate warm air, which is discharged from the warm air outlet, thereby warming the front floor surface and improving the feeling of heating.

Even if only high-temperature gas leaks into the hot air outlet during the radiant heating operation, a part of the air from the blower flows to the hot air outlet, so that heat can be prevented from being trapped and the hot air can be prevented. The temperature rise in the outlet and the vicinity thereof can be prevented, and there is no concern about burns and heat resistance of components disposed in the vicinity of the burn.

Further, during the hot air heating operation in which the air flow switching means has switched the air flow from the blower to the hot air outlet side, a part of the air flow from the blower is passed through the communication port to the hot air outlet. And the amount of the warm air can be increased, and the heating performance by the warm air during the warm air heating operation is improved.

Further, in the apparatus in which an air intake is provided between the high-temperature gas generating means and the blowing means, the air path switching means switches the air flow from the blower to the hot air blowing port side. During operation, when the hot air outlet is closed for any reason, the air flow of the blowing means tries to flow backward from the downstream side of the high-temperature gas generating means, but a part of the air flow passes through the communication port. When the air flows from the air intake port, that is, from the upstream side of the high-temperature gas generating means, it balances with the above-mentioned backflow, so that the accumulation of heat of the high-temperature gas generating means due to the above-mentioned backflow can be reduced.

Further, in the high-temperature gas generating means having a combustion part, the air flow switching means switches the air flow from the blower to the hot air outlet side for some reason during the hot air heating operation. When the hot air outlet is closed, an attempt is made to reduce the supply of combustion air to the combustion section by the air flow of the blower flowing backward from the downstream side of the high-temperature gas generator, when the air outlet of the blower is closed. A part of the flow tries to flow from the air intake through the communication port, that is, from the upstream side of the high-temperature gas generating means, and balances with the above-mentioned backflow, and the combustion air supplied to the combustion section by the above-mentioned backflow Is reduced, and abnormal combustion in the combustion section can be prevented.

In the heating device according to the twelfth aspect, when the air flow from the blower is switched to the radiator cooling air passage side, a part of the air from the blower is heated through the lower side wall of the high-temperature gas generating means. A communication port for discharging the air from the air outlet is provided, and the air flow discharged from the air outlet for the hot air from the blower sucks a large amount of high-temperature gas from the high-temperature gas generating means and does not discharge the air from the air outlet for the hot air. The structure is such that a ventilation plate is arranged above the communication port.

During the radiant heating operation in which the air flow from the blower is switched to the radiator cooling air path side, part of the air from the blower is discharged from the hot air outlet through the lower side wall of the high-temperature gas generating means. The air flow discharged from the hot air outlet from the blower sucks a large amount of high-temperature gas from the high-temperature gas generating means, and is restricted above the communication port so as not to be discharged from the hot air outlet. Since the air plate is provided, in addition to the effect of the eleventh aspect, the high-temperature gas from the high-temperature gas generation means flows smoothly into the radiator heating air path during the radiant heating operation, and the radiation by the high-temperature gas is achieved. The amount of heat collected on the heat collecting surface of the body increases, and the amount of radiant energy from the radiator increases.

Reference numeral 27 denotes the radiator heating air passage 24 and the equipment housing 2.
8 during the radiant heating operation.
In the radiator cooling air path for reducing heat conduction to the radiator cooling air path 27 disposed in the upper part of the apparatus main body, the flowing air flow is discharged from the outlet 27A of the radiator cooling air path 27, and the circulating flow of room air is reduced. It is formed.

Reference numeral 29 denotes a hot air outlet located below the radiator cooling air passage 27 and disposed below the radiator 23. The exhaust gas generated by the combustion section 21 and the indoor air flow are mixed and discharged as hot air. It is supposed to.

Reference numeral 30 denotes a blower for supplying room air as an air flow. This air flow is supplied to a radiator cooling air passage 27 side or a hot air outlet 29 through a main body cooling air passage 31 by air passage switching means 32. It is switched to the side and flows.

A part of the air flow from the blower 30 is
Combined cooling air of a double structure having a space disposed on the outer wall of the combustion tube 22 while being taken into the combustion unit 21 as primary air for combustion from an air intake port 33 disposed between the combustion unit 21 and the blower 30. The cooling air is taken from the cooling opening 35 of the passage 34 and is introduced into the combustion tube 22.
And is taken into the combustion cylinder 22 as secondary air for combustion.

In the above configuration, the air path switching means 32
When the air flow from the blower 30 is switched to the radiator cooling air passage 27 side, the radiant heating operation is performed, the air flow from the blower 30 flows to the radiator cooling air passage 27, and the combustion exhaust gas generated in the combustion unit 21 is The force flowing downward flows considerably above the combustion tube 22, flows further upward due to the draft by the heat, and is guided to the radiator heating air passage 24.

Then, the heat collecting surface 25 of the radiator is heated to a high temperature by the high temperature combustion exhaust gas generated in the combustion section 21, and the heat collecting surface 25
The radiator 23 generates the heat collected by the radiator 23 as radiant energy, so that radiant heating can be performed.

When the air passage switching means 32 switches the air flow from the blower 30 to the hot air outlet 29 side, a warm air heating operation is performed, and the air flow from the blower 30 flows downward in front of the combustion tube 22 and burns. The combustion exhaust gas generated in the section 21 is guided to the hot air outlet side, and the air flow from the blower 30 and the combustion exhaust gas generated in the baking section 21 are mixed, and the hot air discharged from the hot air outlet 29 as hot air is discharged. You will be able to heat it.

Here, during the radiant heating operation, the radiator 23
Since the radiator cooling air passage 27 through which the air flow from the blower 30 flows through the main body cooling air passage 31 is provided between the radiator 23 and the device housing 28 to which the radiator 23 is attached, Heat conduction from the heat from the body 23 to the device housing 28 can be reduced.

Therefore, the blower 3
By switching the airflow from 0 to the radiator cooling air passage 27 side or the hot air outlet 29 side, it is possible to easily switch to the radiant heating operation or sometimes to the hot air heating operation, During the radiant heating operation in which the temperature of the device case 23 becomes high and the temperature of the device case 28 tends to rise due to the heat transfer, the airflow from the blower 30 flows through the radiator cooling air passage 27, so that the temperature of the device case 28 can be kept low. ,
There is no need to worry about burns or heat resistance of components arranged near the radiator 23.

Since the hot air outlet 29 is located below the radiator cooling air passage 27 and is disposed below the radiator 23, the arrangement of the warm air outlet 29 and the radiator 23 is horizontal. It becomes easier to control the amount of the combustion exhaust gas generated in the combustion unit 21 to the amount of the airflow from the blower 30 as compared to the case where the air flow is arranged in other cases.

That is, during the radiant heating operation in which the air flow switching means 32 switches the air flow from the blower 30 to the radiant cooling air passage 27 side, the air flow from the blower 30 flows to the radiant cooling air passage 27. The force that flows into the flue gas to the hot air outlet 29 below the discharge port of the combustion cylinder 22 acts considerably,
The combustion exhaust gas flows upward by the draft by the heat, and is led to the radiator heating air passage 27.

Also, during the hot air heating operation in which the air flow switching means 32 switches the air flow from the blower 30 to the hot air outlet 29 side, the air flow from the blower 30 is
9, the combustion exhaust gas discharged from the combustion tube 22 is guided to the warm air outlet below the discharge port of the combustion tube 22.

Accordingly, the high-temperature gas switching means 32 switches the vertical balance between the draft force for flowing the combustion exhaust gas upward and the force for causing the combustion exhaust gas to flow downward by the airflow from the blower 30. As a result, the flow of the high-temperature gas can be smoothly controlled, and the radiant heating operation and the hot air heating operation can be easily switched.

The high-temperature gas generating means has a combustion section 21 for burning fuel, and generates high-temperature gas by using the combustion gas. Compared to those using other heat sources,
A large amount of heat can be obtained, and a high-temperature gas having a high temperature level can be easily obtained.

That is, in the warm air heating operation, the heating capacity for warming the entire room can be supplemented by the amount of combustion in the combustion section 21, and in the radiant heating operation, combustion exhaust gas having a high temperature level can be obtained. The heat collected by the heat collection surface 25 heated by the exhaust gas can be generated from the radiator 23 as large radiant energy.

The radiator 23 has a large number of through holes 26.
Is provided so that the combustion exhaust gas flows on both surfaces of the radiator 23, and the heat collecting surface 25 of the radiator 23 is formed on both surfaces. And the temperature of the radiator 23 can be raised to a high temperature.
3, the amount generated as radiant energy is greatly improved.

Further, the combustion air to be supplied to the combustion section 21 is provided with an air intake 33 between the combustion section 21 and the blower 30 to take in a part of the air flow from the blower 30 and to supply the air from the blower 30.
