In gap S4.
The venthole of the lower zone of the venthole 30 and side plate interior sides gap S3 of the lower zone of side plate lateral gap S4
30, the ratio with the total opening area of venthole 30 relative to the area of the lower zone of side plate lateral gap S4 is less than venthole
30 total opening area is formed relative to the mode of the ratio of the area of the lower zone of side plate interior sides gap S3.That is, outside side plate
Lower zone of the ratio of the total opening area of the venthole 30 of the lower zone of side clearance S4 than side plate interior sides gap S3 leads to
The ratio of the total opening area of stomata 30 is small.Therefore, the inflow ratio of the air into side plate lateral gap S4 per unit time
The influx of air per unit time into side plate interior sides gap S3 is few.
For support frame side plate 43 in the state that the substantially whole upper surface with distribution grid 31 of lower end contacts, support is solid
Due to distribution grid 31.In addition, support frame side plate 43 generally perpendicularly erects setting from the upper surface of distribution grid 31 upwards.Cause
This, the space of the upper surface slave distribution grid 31 to the top of specified altitude of combustor 21 is divided by support frame side plate 43
It is segmented into burner disposed portion S1 and side plate lateral gap S4.The air of burner disposed portion S1 is flowed into from venthole 30 as a result,
It linearly circulates upwards in burner disposed portion S1, until the height of the upper end more than support frame side plate 43.In addition, from
The air that venthole 30 is flowed into side plate lateral gap S4 in side plate lateral gap S4 to upper straight circulate, until
More than the height of the upper end of support frame side plate 43.
Support frame side plate 43 is located at the outer profile (hereinafter referred to as " burner lid ") than outermost burner 11E with upper end
Mode of 115 upper edge above specified altitude (for example, 2mm) is extended.Therefore, in the S3 of side plate interior sides gap upwards
The air of Fang Liudong after the horizontal edge by the upper edge of burner lid 115, keep intact along support frame side plate 43 by
Top guidance.As a result, in burning operating, it is suppressed that be formed in the burning fire of the top of the glory hole 110 of outermost burner 11E
The extension to the side side plate lateral gap S4 of flame.

Change, and can reduce the noise generated in burning operating.
Further, by making support frame side plate 43 be extended the upper end (flame than outermost burner 11E
Hole forming portion) it is closer to the top, thus in burning operating, between the combustion flame of outermost burner 11E is difficult on the outside of side plate
The extension of the side gap S4.In addition, since the combustion flame of outermost burner 11E is difficult to by from the side plate side lateral gap S4 to outermost
The influence of the air of the side side burner 11E flowing, therefore combustion state is difficult to become unstable.Therefore, it can reduce because of burning
Flame waves caused combustion noise.
In addition, having due to dividing to be formed between the lateral surface and support frame side plate 43 of outermost burner 11E
Gap (side plate interior sides gap) S3 of the left and right width roughly the same with burner gap S2, therefore to outermost burner 11E
110 periphery of glory hole for giving the approximately equal amounts of auxiliary airs in 110 periphery of glory hole of other burners 11.Therefore, in
The fluctuation of combustion state is difficult to happen between the burner 11 of centre and the burner 11 at both ends.Therefore, it can more reduce because of combustion
That makes a fire flame waves caused combustion noise.
Further, in burning operating, between the speed ratio of the air to circulate in the S3 of side plate interior sides gap is on the outside of side plate
The speed of the air to circulate in gap S4 is fast.Therefore, the air to circulate in the S3 of side plate interior sides gap is successfully directed to outermost
110 top of glory hole of side burner 11E.Therefore, the combustion flame of outermost burner 11E is difficult to side plate lateral gap S4
Side extension.In addition, the combustion flame of outermost burner 11E is difficult to by from the side plate side lateral gap S4 to outermost burner
The influence of the air of the side 11E flowing, combustion state are difficult to become unstable.Thereby, it is possible to more more reduce because of combustion flame
Wave caused combustion noise.
In addition, due to the venthole 30 of the lower zone of side plate lateral gap S4 total opening area ratio than in side plate
The ratio of the total opening area of the venthole 30 of the lower zone of side clearance S3 is small, so every list into side plate lateral gap S4
The influx of air per unit time of the inflow ratio of the air of position time into side plate interior sides gap S3 is few.Therefore, most
The combustion flame of outside burner 11E is difficult to extend to the side plate side lateral gap S4.In addition, the burning of outermost burner 11E
Flame is difficult to the influence by the air flowed from the side plate side lateral gap S4 to the outermost side burner 11E, and combustion state is difficult
To become unstable.Combustion noise caused by thereby, it is possible to more more reduce because of the waving of combustion flame.
In addition, in the above-described embodiment, for the ventilating air in side plate lateral gap S4, in the side plate of distribution grid 31
The lower zone of lateral gap S4 opens up venthole 30.As long as however, being able to suppress the combustion flame of outermost burner 11E
Extension to the side side plate lateral gap S4, then in order not to import air to side plate lateral gap S4, can also be on the outside of the side plate between
The lower zone of gap S4 does not open up venthole 30.
In addition, in the above-described embodiment, venthole 30 by opening at a prescribed interval on the front-rear direction of distribution grid 31
If small sircle hole constitute.However, as long as air is properly directed into outside burner gap S2, side plate interior sides gap S3 and side plate
Side clearance S4, venthole 30 can also be made of longer single or multiple slits in the longitudinal direction.
In addition, the present invention is not limited to only with the water heater of heat water supply functions, be readily applicable to bathing pool supplement
The water heater of heating function.In addition, the present invention is readily applicable to the heating heat to warm water heating terminal circulation supply warm water

According to above-mentioned burner, when the per unit of the air flowed into side plate lateral gap via the venthole of distribution grid
Between the air that is flowed into side plate interior sides gap via the venthole of distribution grid of inflow ratio influx per unit time it is few.
Therefore, it is difficult to flow to outermost burner side from the air that side plate lateral gap flows out upwards, the combustion of outermost burner
Burning state is difficult to become unstable.Therefore, combustion noise caused by capable of more more reducing because of the waving of combustion flame.
