Patent attributes
Disclosed is a space heater, with an air cleaning function, that monitors combustion at a burner, and prevents the halting of combustion due to the erroneous detection of a combustion abnormality. According to the present invention, a space heater includes: a heating unit control unit, which performs a “heating operation” for igniting fuel gas at a burner to operate a heating fan; an air cleaning unit control unit, which performs an “air cleaning operation” for operating an ion generator and an air cleaning fan; a combustion forced halt unit, for monitoring the combustion state of the burner based on a thermoelectromotive force TC generated by a thermocouple, and for halting combustion at the burner when the thermoelectromotive force TC drops, from a reference value TC_b, the equivalent of a determination level TC_j or more; and a reference value setup unit for, when the mode is shifted from an “independent heating mode”, during which only the “heating operation” is performed, to a “synchronous operating mode”, during which both the “heating operation” and the “air cleaning operation” are performed, designating as the reference value TC_b the thermoelectromotive force TC, generated by the thermocouple 16, that is stabilized after mode switch.
