Combustion device and hot air heating device

摘要

PROBLEM TO BE SOLVED: To provide a combustion device and a hot air heating device capable of improving the accuracy of time calculation. An oscillation device including a combustion unit that burns fuel, includes an oscillator 8 having a predetermined frequency temperature characteristic, and generates a clock signal having a frequency corresponding to the oscillation frequency of the oscillator 8. A temperature sensor 6 which is arranged apart from the circuit unit 8A and the oscillator 8 and detects the temperature of the air at the arranged position, and a flame sensor 18 which detects whether the combustion unit is in a burning state or a non-burning state. The temperature estimation unit 52 that obtains the estimated temperature of the oscillator 8 based on the detection temperature of the temperature sensor 6 and the detection result of the combustion state detection unit, and the estimated temperature of the oscillator 8 and the oscillation circuit unit that are obtained by the temperature estimation unit 52. It includes a time calculation unit 53 that calculates the current time based on the clock signal output from 8A. [Selection diagram] Fig. 5
