GAS PREMIX BURNER AND GAS WATER HEATER

摘要

A gas premix burner and a gas water heater. The gas premix burner (10) is provided with a burning direction (F), the gas premix burner (10) is matched with a premix cavity arranged at the upstream of the burning direction (F) of the gas premix burner (10), and gas and air are burned via the gas premix burner (10) after being mixed in the premix cavity. The gas premix burner (10) comprises: a burner substrate (11), main burning holes (13) being arranged on the burner substrate (11). Auxiliary burning holes (15) arranged along the burning direction (F) at the downstream of the main burning holes (13) are also provided on the burner substrate (11). Auxiliary flames of the auxiliary burning holes (15) and main flames of the main burning holes (13) intersect. The main burning holes (13) are arranged along the burning direction (F) at the upstream of the auxiliary burning holes (15) so that the main flames are arranged at the upstream of the auxiliary flames, it is easier for the auxiliary flames and the main flames to intersect, and opposed firing of the flames is formed between the auxiliary flames and the main flames to implement a stable flame effect.
