Abstract

PURPOSE:To make serviceable the period capable of braking for a convection fan during a specific operation. CONSTITUTION:This control device provides a combustion section, a convection fan 19 which blasts high temperature gas as a hot temperature air from the combustion section outside an equipment main body, a combustion control section 22 which performs operations, such as combustion starting, combustion volume control and combustion shutdown and a convection fan braking section 24 which brakes the convection fan 19. This device forces the convection fan braking section 24 to operate by carrying out a specific operation based on an operation command section 25 during the drive of the convection fan 19. This construction makes it possible to reduce inspection time during quality inspection time in a manufacturing process and hence reduce cost, and what is more, to obtain odor reduction effect during extinguishment.

In step 30 of FIG. 2, after the operation command is issued in step 26, it is determined whether the normal combustion or the inspection operation is performed. Here, if the combustion control unit 22 does not receive the command signal from the operation command unit 25 as the inspection operation signal, the operation proceeds to the combustion start of the next stroke. Otherwise,
If there is an inspection operation signal in the command signal, the combustion control unit 22 outputs a signal for driving or stopping the combustion pump 5, the combustion blower 6, and the convection blower 19 as an inspection operation. During the inspection operation process, if the combustion control unit 22 receives a signal for performing a specific operation from the operation command unit 25 to perform the convection blower braking, the process proceeds to step 31, and the convection blower braking determination unit 32 determines.
