cooktop burner

Abstract

The invention provides a cooker burner, which includes an outer ring fire cover, two outer ring injection pipes and a flow guide block, the gas outlet ends of the two outer ring injection pipes are arranged oppositely, and both are connected to the outer ring fire cover In the inner outer ring gas mixing chamber, the guide block is arranged between the two gas outlet ends, and has guide surfaces facing the two gas outlet ends respectively, and the guide surface can change the gas flow direction of the two gas outlet ends to a direction away from each other flow. The cooker burner provided by the present invention is provided with a guide block between the two gas outlet ends, so that the two opposite guide surfaces of the guide block are used to change the flow direction of the gas flowing out of the gas outlet end, so that each of them flows in a direction away from each other. Ensure that the gas flow in the outer ring gas mixing chamber and the gas at each fire hole are relatively stable and even, avoid the gas at the two gas outlets from hedging, solve the problem of flame separation and tempering in the fire hole caused by gas hedging, and avoid The large loss of fuel-air mixture energy caused by hedging reduces the problem of ejection capability.

Description

technical field [0001] The invention particularly relates to a cooker burner. Background technique [0002] The traditional bottom-intake stove burner has the advantages of high heat load and large firepower. However, since the air replenishment of the bottom air-intake burner is carried out in the cabinet, it is easy to cause insufficient air replenishment, resulting in insufficient combustion, yellow flame and high carbon monoxide concentration. Therefore, an upward air intake type stove burner was created to solve the problem of insufficient air supplementation. [0003] However, due to the short ejector tube of the upward air-intake burner, there is no contraction section and expansion section in the traditional sense, or the size of the ejector tube contraction section is reduced and the function is weakened, resulting in insufficient ejection capacity, so generally at least Two ejector tubes to increase the combustion load of the burner. In order not to affect the n...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a cooker burner in order to overcome the defect that the ejector tube of the upper air inlet burner in the prior art has an unstable combustion state at the fire hole due to the relative outlet.
