Carbon dioxide concentration measuring device, method of measuring carbon dioxide concentration and burning appliance therefor

摘要

A carbon dioxide concentration measuring device or a method of measuring carbon dioxide concentration which can measure the carbon dioxide concentration in outside air with high accuracy is provided. A carbon dioxide sensor mounted in a heating appliance includes a generator which generates electric power through the use of combustion heat, more specifically through directly converting the heat energy of combustion heat from a flame for heating into electrical energy. The carbon dioxide sensor operates through the use of electrical energy generated by the generator, so unlike a carbon dioxide sensor in a related art which operates through the use of a consumable power source such as a dry cell, as long as electrical energy is generated by the generator, the emission intensity of infrared rays does not change with time, or a computing process by a control circuit is not impeded, so an error due to a change in the emission intensity of infrared rays or the impediment to the computing process by the control circuit in the result of measurement of carbon dioxide concentration is impeded.
