[ detailed description ] embodiments

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1 to 5, a burner structure of a gas water heater, including burner housing 1, the air inlet 11 that supplies secondary air to get into burner housing 1 on burner housing 1, the interval is equipped with a plurality of fire rows 2 in burner housing 1, is equipped with airflow channel 3 between the adjacent fire row 2, be equipped with on fire row 2 air inlet 21 and with the hybrid chamber 22 of air inlet 21 intercommunication is equipped with inside sunken recess 4 on the fire row 2, be equipped with on recess 4 a plurality of with the fire outlet 41 of hybrid chamber 22 intercommunication, be equipped with on fire row 2 both sides of recess 4 upwards and to airflow channel 3 one side slope's fire blocking piece 23. The utility model discloses a set up inside sunken recess 4 on fire row 2, make two adjacent fire rows between 2 clearance when becoming flame concentrate to the centre, adjacent flame is difficult to interfere, play the flame stabilizing effect, reduce the combustion noise, and the fender fire piece 23 that the slope set up then enables the air that blocks the part and upwards flow, the air can flow along fender fire piece 23 skew wall under the direction of fender fire piece 23, avoid the direct straight upflow of air to walk, effectively reduce the wind noise and guarantee the required secondary air of burning like this, moreover, the steam generator is simple in structure, improve the burning operating mode, reduce the combustor noise, can realize with the size reduction of size increase load or with the load, product cost is reduced, product competitiveness is improved.

Specifically, the groove 4 is a V-shaped groove, and the fire outlets 41 are symmetrically arranged on the V-shaped side wall of the V-shaped groove. The fire holes 41 are respectively arranged on two side walls of the V-shaped groove in a split mode.
