[0002] The gas distributor rod is the core working part of the gas water heater. The gas distributor rod assembly has an air inlet channel and several air outlets connected to the air inlet channel. A valve body is provided on the gas distributor rod assembly. The intelligent controller system controls the on-off of the air inlet channel by controlling the valve body, and then controls the flow of gas to achieve the gas flow required for the combustion of the set water temperature.

[0003] In order to achieve water temperature control, existing gas distribution rods mostly adopt a segmented combined combustion heating method. The segmented combustion nozzles are installed in a segmented and side-by-side distribution. When low-power combined combustion heating is performed, due to the interval between segmented work, only some nozzles are burning, which will form a large low-temperature area inside the combustion chamber. Due to the temperature difference effect, it is easy to cause condensation and accumulation of water vapor. Therefore, a multi-segmented uniform flame gas distribution rod structure is proposed to effectively reduce the condensed water generated by combustion. Utility Model Content

Different from the traditional segmented combustion structure, the combustion nozzles in the gas guide channel are distributed alternately at intervals. This structure ensures that when the whole machine uses different gas chambers to supply gas for heating at a lower load, the flame burns in an alternating interval manner, which can not only increase the total combustion width of the flame, but also avoid the occurrence of no-load gaps. It can effectively reduce the low-temperature area inside the combustion chamber during segmented combustion, thereby solving the problem of excessive condensed water caused by the low temperature inside the burner.
