Description

Instantaneous ignition and instant fire control method of a cooker

technical field

The invention relates to a household gas cooker.

Background technique

At present, most of the ignition methods of embedded cookers use inner ring ignition. Because the inner ring nozzle is too small, it is easy to leave the flame and lose fire in the cold state, resulting in a low ignition success rate. Some stoves adopt a bypass copper pipe from the valve body, and mechanically, when the valve stem is pressed down, the valve core sealing ring in the valve body is pushed open, and the gas is introduced from the valve core to the burner through the bypass copper pipe, increasing the gas consumption. Concentration, to achieve the purpose of increasing the ignition rate. Defects of this technology: When igniting, you must press the knob for a long time with your hand, press down the valve stem, and open the valve core sealing ring, so that the gas can enter the burner from the bypass copper pipe, but after you let go, the valve core spring The reset immediately cuts off the gas source of the bypass copper pipe.

The bypass pipe is closed;

(2) Press down on the valve stem and then leave the hand, the pressure plate cooperates with the second micro switch, the solenoid valve core assembly is energized, the bypass pipe conducts, the solenoid valve core assembly delays after being energized, and then closes to realize automatic instantaneous fire;

(3) Press down on the valve stem and then leave the hand, the pressure plate cooperates with the second micro switch, the solenoid valve core assembly is energized, the bypass pipe conducts, the solenoid valve core assembly delays after being energized, and then closes to realize automatic instantaneous fire.

(4) Turn the valve stem in the opposite direction, the pressure plate is separated from the first micro switch, and the main solenoid valve is powered off and closed.

The present invention relates to a cooker instantaneous ignition and instantaneous high fire control method. When the valve stem is pressed down and rotated, the bypass pipe, the central air outlet pipe and the outer ring air outlet pipe enter and conduct at the same time, and the amount of gas entering the central fire cover is large, increasing ignition When the gas concentration is constant, the success rate of ignition is improved; when the fire is instantaneous, it can be realized by simply pressing the valve stem, and the operation is convenient.
