Abstract
Description
Technical Field
[0001] This utility model relates to the field of household electrical appliances technology, specifically to a burner for gas equipment. Background Technology
[0002] As is well known, gas stoves are a common kitchen appliance in daily life. The core component of a gas stove is the burner, or combustion chamber. A typical burner includes a burner cap and a gas distribution plate. The burner cap is placed above the gas distribution plate, which guides the gas flow into the burner cap, providing gas for combustion. Simultaneously, the gas distribution plate typically has two, three, or four gas passages, defining secondary air channels. This secondary air flows through these channels to the burner cap, providing secondary air for combustion, improving the flame combustion effect, and reducing smoke production. Existing burners typically have an inner ring burner cap and an outer ring burner cap. While leaving a wide secondary air channel between the burner caps can significantly increase the amount of secondary air, the lack of guidance means that the secondary air cannot effectively reach the flame root. Consequently, CO emissions are not reduced, and the increased secondary air mixing with the flue gas actually lowers the flue gas temperature, reducing thermal efficiency. Therefore, a flow guiding mechanism can be designed on the gas distribution plate to guide the secondary air to the flame holes of the inner and outer ring burner caps. This would increase the secondary air supply to the burner, improve the oxygen supply capacity of the flame, enhance combustion, increase thermal efficiency, and reduce CO emissions.
