And part 10.

In the heat storage combustion heating apparatus, when combustion air is supplied by the burner fan 4 to burn the burner 2, exhaust gas is discharged from the outlet of the combustion tube 3 and reaches the mixing section 7. On the other hand, the airflow supplied from the convection fan 5 has its flow direction regulated by the guides 6 and 6 ', reaches the mixing section 7, and is mixed with the exhaust gas. The heat storage member 8 is heated by this mixed flow, and then the mixed flow is blown out as warm air from the warm air outlet 9. When combustion stops, convection fan 5
The supplied airflow receives heat from the heat storage unit 8 and continues to emit warm air for a certain period of time after combustion.

However, in the above-mentioned conventional configuration, the high temperature exhaust gas obtained by combustion is mixed with the low temperature air flow supplied from the convection fan 5, and the heat storage section 8 is heated after the temperature is lowered. Therefore, there is a problem that the temperature of the heat storage section 8 does not rise sufficiently, and therefore the amount of heat storage also decreases. Furthermore, the high-temperature exhaust gas obtained by combustion does not give a heat quantity to the heat storage section 8 and requires an operation mode in which all the heat quantity is blown out as warm air, but it is configured to pass in contact with the heat storage section 8. However, I also had a problem that I could not do that. Further, even after the combustion is stopped, even in the heat storage heating mode in which heat is exchanged between the airflow supplied from the convection fan 5 and the warm air in the heat storage section 8 that has stored heat, the temperature is lowered by being mixed with the supplied low-temperature airflow and the warm feeling There was also a problem that it was difficult to obtain.

And a heat storage portion that is heated and stored by the combustion gas of the burner and radiates heat when combustion is stopped,
Provided between the heat storage unit and the blower, most of the indoor air blown by the blower passes through in contact with the heat storage unit when opened, and most of the indoor air blown by the blower when closed. A damper that operates so as to pass around the combustion cylinder without contacting the heat storage part, and the damper is opened to allow the room air from the blower to mix with the combustion gas of the burner in the space above the combustion cylinder to generate warm air. Combustion heating mode that blows out from the hot air outlet, the damper gas is closed and the combustion gas of the burner heats and stores the heat storage section, and then mixed with room air from the blower and blown out from the hot air outlet as hot air. Heat storage combustion mode to stop, combustion of the burner is stopped, the damper is opened and the indoor air from the blower exchanges contact heat with the heat storage unit, and the heat storage heating mode is blown from the hot air outlet as warm air. Regenerative combustion heating system which de is composed of a control unit can select switch.
