Fuel gas mixing device, ejection device and cooker

Abstract

The invention belongs to the technical field of burners, and particularly relates to a fuel gas mixing device, an ejection device and a cooker. The fuel gas mixing device comprises mixing cavities, gas inlets and gas outlets, wherein the gas inlets and the gas outlets communicate with the mixing cavities; and the mixing cavities are internally provided with mixing blocks, and combustible gas entering from the gas inlets is output through the gas outlets after passing through the mixing blocks. Gas flow enters the mixing cavities through the gas inlets to be buffered, and the gas pressure fluctuation is reduced; meanwhile, gas flow in the mixing cavities is distributed through the mixing blocks, thus, fuel gas and air are further sufficiently mixed and then flow out uniformly through the gas outlets, and the fuel gas and the air are sufficiently mixed; and the mixing effect is improved, the situation that the yellow flame phenomenon occurs to the cooker is avoided, flames are more stable, and the energy efficiency of the cooker is improved.

Description

technical field [0001] The invention belongs to the technical field of burners, and in particular relates to a gas mixing device, an injection device and a cooker. Background technique [0002] The cooker ejector is one of the important components of the burner. It injects the air in the surrounding environment into the ejector through the flow of gas, and the gas is drawn from the ejector to the burner for combustion. Traditional burners generally use The single-nozzle ejector tube with damper adjustment, the gas combustion flame caused by the single-nozzle ejector is uneven in length and weak. In order to enhance the injection capability of the injection tube, burners using multi-nozzle injection tubes have appeared on the market at present, and the gas is induced by means of multiple tubes and multiple injections, but this structure still has the problem of low mixing degree of gas and air. problems, thus affecting the energy efficiency of gas combustion.

Problems solved by technology

[0002] The cooker ejector is one of the important components of the burner. It injects the air in the surrounding environment into the ejector through the flow of gas, and the gas is drawn from the ejector to the burner for combustion. Traditional burners generally use Single-nozzle ejector tube with damper adjustment, the gas combustion flame length caused by the single-nozzle ejector is uneven and weak

In order to enhance the injection capability of the injection tube, burners using multi-nozzle injection tubes have appeared on the market at present, and the gas is induced by means of multiple tubes and multiple injections, but this structure still has the problem of low mixing degree of gas and air. problems, thus affecting the energy efficiency of gas combustion

In addition, when the existing multi-tube injection tubes are mass-produced, sand casting is used as an integrated structure, which is inconvenient to process and low in manufacturing efficiency.
