Description

Burner and gas water heater Technical Field The utility model relates to the technical field of gas equipment, in particular to a combustor and a gas water heater. Background As a core device for domestic hot water supply, the safety, energy efficiency ratio and service life of the gas water heater are very critical aspects for users. In the prior art, be provided with the combustor in the gas heater, the combustor can last burning and heat cold water to demand temperature through the mode of heat transfer to satisfy user's use, in order to ensure simultaneously that the temperature of combustor shell can not continuously rise, still can set up forced air cooling module or water-cooling module on the combustor, in order to carry out cooling to the shell of combustor, protect other components and parts. However, the heat distribution inside the burner is uneven, in actual operation, the temperature distribution of the burner housing is uneven, the partial area is closer to the heat radiation, the temperature is higher, and when the module is cooled, the parts with higher or lower housing temperature are difficult to be considered, so that the heat dissipation effect of the high-temperature area is poor, the transition heat dissipation of the low-temperature area is influenced, the temperature inside the burner is influenced, the temperature difference of each area on the surface of the housing is larger, the aging of the housing is accelerated, the local deformation is easily caused, and the high-temperature smoke leaks to influence the safety of other components. Disclosure of utility model The utility model aims to provide a combustor and a gas water heater, and solves the problems that in the prior art, the heat dissipation effect of a combustor shell is uneven, so that the temperature difference of each area of the shell is large, the shell is aged rapidly, local deformation is easy to occur, and the safety of other components is influenced due to leakage of high-temperature smoke. To achieve the purpose, the utility model adopts the following technical scheme: in a first aspect, the present utility model provides a burner comprising: The shell, the lateral wall of shell has the interval and is equipped with first air intake and second air intake, first air intake includes a plurality of first fresh air inlet, the second air intake includes a plurality of second fresh air inlet, wherein, a plurality of first fresh air inlet or a plurality of second fresh air inlet is along first direction non-equidistant distribution.
