PURPOSE:To manufacture a fuel gas combustion controller for a heating cooker, rise time thereof is fast, by positively elevating the temperature of the inside of a box by full power during preheating time. CONSTITUTION:When the temperature of the inside of a box in a combination range is set at 300 deg.C in a sliding volume control knob in a display board, a spring 47 positioned in a connecting section for a proportional governor 44 is compressed, and a rod 50 for the proportional governor 44 also compresses a governor spring 51, thus resulting in the maximum flow rate of a gas. When gas pressure is made higher than standard one at that time, the governor spring 51 shrinks, and the flow rate of the gas is reduced. Consequently, the titled controller displays an effect of which the gas can be made constant to the flow rate of the gas proportional to the temperature and gas pressure by one solenoid valve and one governor. When a gas oven timer is positioned at the position of preheating, a fixed magnet 55 works in the direction that it pushes the governor spring 51 because a microswitch 37 is turned ON and a solenoid coil 54 is excited. Accordingly, high power is obtained, and the time required for cooking can be shortened. |
