<p>PURPOSE:To improve controllability by controlling quantity of fuel supply and hot air flow based on storage inside temperature, outside air temperature, and the opening/closing condition of a door, in a combustion type hot storage. CONSTITUTION:A controller 4 receives an outside air temperature signal from an outside air temperature sensor 35, a storage inside temperature signal from a storage temperature sensor 34, computes difference between setting temperature Tc and storage inside temperature Tr, and compares it with a setting temperature deviation DELTATc. At Tc-Tr>DELTATc, a combustion apparatus 1 is on and the storage is heated. And it is rapidly heated with increased air flow from a blower 21 and increased fuel supply quantity from a fuel pump 15. At Tc=Tr, the combustion apparatus 1 is stopped, and hereafter air flow is controlled according to relation between Tc, Tr and DELTATc. At Tc-Tr<DELTATc, air flow and fuel flow are controlled according to a tub opening/closing signal from a door sensor 32. For example, when the door is opened and outside temperature is lower than the setting temperature, air flow and fuel flow are increased. By this constitution controllability is improved.</p> |
