Title: Warm air room heater
Inventor: HARA SHOICHI
IPC: F24H3/04
Filed: 1985-11-20
Abstract: PURPOSE:To make it possible that stable state of combustion is always obtained by delaying the time point of control for amount of combustion from the time point of control for the speed of fan rotation in a hot air room heater which has a function to control a fan for delivering hot air out and the amount of combustion. CONSTITUTION:In an electric passage from a microcomputer 9 to a proportional valve 12 a resistor 18 is inserted between an operation amplifier 14 and the branch point of a capacitor 15. Namely, because supply of electric current to the capacitor 15 is delayed by the action of the resistor 18, which delays the supply of signal voltage applied to the base of a transistor 17, variation in the amount of combustion gives rise to a time delay in the response of a proportional valve 12 which controls amount of combustion, and this delay is synchronized with a variation in the rotational speed due to fan inertia. Accordingly the air-to-fuel ratio of a burner becomes uniform and stable combustion is given by the burner.
