Detailed Description

Referring to fig. 1 to 4 in combination, according to an embodiment of the present invention, there is provided a fire grate cover, including a cover body 1, a plurality of fire holes 11 are configured on the cover body 1, a flange ring 12 is configured at an outlet of the fire holes 11, the flange ring 12 extends toward an ejection direction of flames, and the flange ring 12 surrounds the outlet. In the technical scheme, the flange ring 12 is arranged at the outlet of the fire hole 11 to enable the flames in each fire hole 11 to be independently ejected and not interfered with each other, so that the flame noise generated by the fact that the flame position and the shape of the flames are irregularly and rapidly changed to generate disturbance when the heat load is high can be effectively avoided, the combustion noise is reduced from the noise source head in the mode, the noise reduction effect is better, the fire grate cover is simple in structure, the silencing cotton is not required to be pasted at the positions such as the outer shell and the like in the prior art to block and eliminate the noise, the production cost of the water heater is reduced, the production efficiency is improved, and the experience satisfaction of a user can be improved by the gas water heater with smaller noise.

The height h of the flange ring 12 should not be too high or too low, and too low will not guarantee the separation effect of the flame in the fire hole 11, and too high makes the gap between the burner and the heat pipe above the burner too narrow and small, which is not favorable for the space compact design, preferably, 1.5mm is not more than h not more than 4m, and further, h is 2 mm.

In the technical scheme, the shape of the through hole of the flange ring 12 is the same as the shape of the outlet of the fire hole 11, and the size of the through hole of the flange ring 12 is the same as the size of the outlet of the fire hole 11.

Preferably, the cover body 1 has a first surface, a plurality of the fire holes 11 are disposed on the first surface, the first surface is formed by a first side 13 and a second side 14 that intersect with each other, and the plurality of the fire holes 11 are symmetrical with respect to an intersection line of the first side 13 and the second side 14, that is, the flange rings 12 are also symmetrically distributed with respect to the intersection line.

Preferably, any plane perpendicular to the intersecting line is a first plane, the projection of the first surface on the first plane is in a V shape, the fire holes 11 are also in a V shape at this time, the fire holes arranged in a V shape can enable flames to generate a flame gathering effect, and along the length direction of the fire grate cover, the interference phenomenon between every two adjacent fire holes 11 is further eliminated, so that the upper airflow of the flames can be maintained in a stable state, and the combustion noise is further reduced.
