Claims

[Claims for Utility Model Registration] ■ A blower 1 that is equipped with a rotation speed changing mechanism IA and that can adjust the amount of air supplied to the burner 3 by changing the rotation speed by the mechanism IA, and The forced combustion device is equipped with a zero governor 8 that automatically adjusts the amount of gas supplied, and a mechanism 17 that can switch the amount of air and gas supplied in multiple stages by changing the passage area of each air and gas supply path. In conjunction with the switching operation of the supply amount switching mechanism 17, the air supply amount immediately after switching is the same as the air supply amount immediately before switching.
Or the blower rotation speed changing mechanism I so that it becomes almost the same.
A forced combustion device characterized by being provided with a control mechanism C that automatically adjusts A. ■ The control mechanism C, in conjunction with the switching operation of the supply amount switching mechanism 17 from the small supply amount state to the large supply amount state, causes the air supply amount immediately after switching to be slightly smaller than the air supply amount immediately before switching. The forced combustion device according to claim 0 of the utility model registration, which automatically adjusts the blower rotation speed changing mechanism IA so that the rotation speed of the blower changes.
