Title: Control device for hot air heater
Inventor: MATSUDA YUKIKAZU
IPC: F23N3/00
Filed: 1987-06-17
Abstract: PURPOSE:To provide the desirable temperature of hot air, by a method wherein a combustion amount varied together with a blast amount of hot air according to a room temperature is corrected by means of a correcting means. CONSTITUTION:A pulse frequency outputted to a solenoid pump 3 is calculated according to a difference between a room temperature detected by a room temperature detector 7 and a set temperature. The number of revolutions of a blower 8 corresponding to the calculated combustion amount is calculated, and a phase amount corresponding to the number of revolutions of the blower is outputted from an output part to the blower 8. Only a combustion amount is controllable without changing a blast amount. Since, with a switch 16 pressed, a blast amount remains unchanged and a combustion amount is decreased, the temperature of hot air can be reduced. Inversely, when rapid heating is desired, a switch 18 may be pressed.
