<p>Disclosed is a heating device provided with: a heating chamber that contains an object to be heated; a heater; an exhaust port; an exhaust fan that expels air from the heating chamber via the exhaust port; and a filter that removes oil fumes from exhaust gas from the heating chamber. The disclosed heating device is also provided with: a first temperature-measurement unit that measures the temperature inside the heating chamber; a second temperature-measurement unit that measures the temperature of the air expelled from the exhaust port; and a controller that determines whether or not the filter has gotten full on the basis of the speed of the exhaust fan and the difference between the temperature (TO) inside the heating chamber and the temperature (Tex) of the air expelled from the exhaust port.</p> |
