Thepartition plate 13 is provided between thefirst sheet 11 and thesecond sheet 12 and located above themixing chamber 101. Thepartition plate 13 has a front side and a rear side which are connected to opposite sides of thefirst sheet 11 and thesecond sheet 12 respectively. Thepartition plate 13 has the main outlet, thepartition plate 13 and at least one of thefirst sheet 11 and thesecond sheet 12 define the assistant outlet. For example, thepartition plate 13 and one of thefirst sheet 11 and thesecond sheet 12 define the assistant outlet, or each of two sides of thepartition plate 13 and the correspondingfirst sheet 11 orsecond sheet 12 define the assistant outlet, at this time, assistant outlets are provided at both sides of the main outlet. - In the
burner 100 according to embodiments of the present disclosure, by defining the assistant outlet at a side of the main outlet by means of thepartition plate 13 and at least one of thefirst sheet 11 and thesecond sheet 12, the area of outlet can be increased. The assistant outlet is in direct communication with themixing chamber 101, not only the thermal load can be raised, but also improvement in the quality and usage index of the gas water heater is benefited, which satisfies operating requirements of the complete machine. Therefore, theburner 100 has a large area of the outlet and a simple structure, and is convenient to manufacture and good in adaptation. - The gas water heater according to embodiments of the present disclosure is stable in combustion flame, high in thermal load, and good in performance, by adopting the
burner 100 with the main outlet and the assistant outlet(s) defined by thepartition plate 13 and thefirst sheet 11 as well as/or thesecond sheet 12. - Some specific embodiments of the
