Gas cooker capable of continuously regulating firepower

Abstract

The invention discloses a gas cooker capable of continuously regulating firepower. The gas cooker comprises a combustor, an electromagnetic valve used for controlling the flow of fuel entering the combustor, and a controller used for controlling the electromagnetic valve, wherein the combustor comprises an inner-ring nozzle and an outer-ring nozzle, the electromagnetic valve comprises a valve body, a fuel inlet and a plurality of gas outlets communicated with the gas inlet respectively are formed in the valve body, the gas outlets comprise an inner-ring gas outlet communicated with the inner-ring nozzle and a plurality of gas outlets which can be simultaneously communicated with the outer-ring nozzle, all the gas outlets are respectively internally provided with valve cores which can be used for controlling opening / closing of the gas outlets and / or the opening degree, and a plurality of electromagnets capable of singly controlling the valve cores to independently act are arranged correspondingly on the valve body. The gas cooker is capable of flexibly regulating the firepower so as to adapt to different demands, can prevent the fuel in the inner-ring nozzle from being wasted, caused by incomplete combustion due to overlarge flow, and has the convenient and energy-saving effects.

Description

technical field [0001] The invention relates to a gas cooker, in particular to a gas cooker which can continuously adjust the firepower. Background technique [0002] Gas cookers are widely used in people's daily life. In recent years, more and more gas cookers have begun to use solenoid valves to control the gas flow and then the firepower, which greatly facilitates the use of gas cookers. However, the burners in the existing gas cookers usually have inner nozzles and outer nozzles, and the current gas cookers usually only use a solenoid valve to control the gas flow of a single nozzle or two nozzles at the same time, so that the two The flames of two nozzles have the same size, and the number of gears for firepower adjustment is less, and when the object to be heated is smaller than the size of the outer ring nozzle, the flame of the outer ring nozzle cannot play a heating role, resulting in energy waste; and because the outer ring The nozzle is larger than the inner ring...

However, the burners in the existing gas cookers usually have inner nozzles and outer nozzles, and the current gas cookers usually only use a solenoid valve to control the gas flow of a single nozzle or two nozzles at the same time, so that the two The flames of two nozzles have the same size, and the number of gears for firepower adjustment is less, and when the object to be heated is smaller than the size of the outer ring nozzle, the flame of the outer ring nozzle cannot play a heating role, resulting in energy waste; and because the outer ring The nozzle is larger than the inner ring nozzle, and the gas flow required for the same flame size is more than that of the inner ring, and the size of each gas outlet of most solenoid valves is the same, so the gas flow supplied to the inner ring nozzle and the outer ring nozzle Just the same, when the firepower is high, the gas in the inner ring nozzle cannot be completely burned, wasting gas resources, customizing solenoid valves with different gas outlet sizes will increase the cost of the product, and it is not conducive to maintenance and replacement when the solenoid valve fails
