Through the arrangement of the matrix distribution, the first air inlet holes 105 in the second area 102 and the third area 103 can be better distributed in the area corresponding to the first wind shield 10, so that air inlet in each area of the combustor is more balanced, and the combustion condition of the combustor is better. Meanwhile, the smaller distribution density of the second air inlet holes 106 in the second area 102 can provide enough air for combustion while avoiding influencing the ignition effect, and finally, the larger density of the third air inlet holes 107 in the third area 103 can provide enough air for combustion, and meanwhile, the flame can be folded easily, and the heating efficiency is improved. Specifically, the second air inlet holes 106 in the second region 102 are arranged on the front side of the first windshield 10, the number of the second air inlet holes 106 in the second region 102 is 50, the second air inlet holes 106 are through holes with the diameter Φ 3mm, and the distance between two adjacent second air inlet holes 106 is 7.7mm; the third air inlet holes 107 in the third region 103 are located in the middle of the first air deflector 10, 200 third air inlet holes 107 in the third region 103 are through holes with a diameter Φ 3mm, and an effect that the distance between two adjacent third air inlet holes 107 is 5mm is good.

In this embodiment, referring to fig. 1 and 4, the first air inlet holes 105, the second air inlet holes 106, and the third air inlet holes 107 have the same diameter. Through the arrangement, the opening areas of the first air inlet 105, the second air inlet 106 and the third air inlet 107 are set to be consistent, the difficulty of mold design and mold opening can be reduced, the working strength of workers is reduced, and the processing is convenient.

In this embodiment, referring to fig. 1 and 4, a region of the first wind deflector 10 facing the rear end of the bottom of the fire row group 40 is a first closing region 104, and the first closing region 104 is located at the rear side of the third region 103. Through the setting of first closed region 104, do not set up the through-hole in this region, because this region comparatively is close to the fire hole position of fire bank group 40, thereby it can avoid too close the fire hole to lead to the flame on the fire hole to deviate toward combustor casing inside wall to seal the setting here, avoids appearing the condition that casing rear end high temperature, influences the operation of fire bank group 40 and the effect of heating of water heater, improves the stability that fire bank group 40 operated.

In combination with the arrangement of the first sealing area 104, in the present embodiment, as shown in fig. 1 and 4, an extension area 108 extending to the first sealing area 104 is provided on the left side or the right side of the third area 103, and the third air inlet 107 is disposed in the extension area 108.
