Document Type and Number:
WIPO Patent Application WO/2021/223341
Kind Code:
A1
Abstract:
A household cooking stove combustor having upper wind intake and ultra large power, comprising a cup (1), a fire cap seat (2), a central fire cap (3), an outer ring fire cap (4), an ignition needle (5), an induction needle (6), a gas inlet seat (7), a central gas inlet pipe (8), a left gas inlet pipe (9) and a right gas inlet pipe (10). A central gap is formed between the central gas inlet pipe (8) and a light cylinder part (132) of a central fire gas inlet pipe (13); a right gap is formed between the left gas inlet pipe (9) and a left light cylinder part (152) of a left outer ring gas inlet pipe (15); a left gap is formed between the right gas inlet pipe (10) and a right light cylinder part (162) of the right outer ring gas inlet pipe (16); a lower end of a gas inlet cavity (2B) of the fire cap seat (2) is joined to an outer ring premixing cavity (14); and an outer interface (44) of the outer ring fire cover (4) is inserted into an outer ring fuel gas groove (3A), and an inner ring wall plate of the outer ring fuel gas groove (3A) is inserted into the outer ring fire cover (4). The provision of an outer ring flame stabilizing groove (432) and a flame stabilizing plate (45) on the outer ring fire cap (4) prevents flying flames of the outer ring fire from occurring. The provision of the gap between the central gas inlet pipe (8) and the light cylinder part (132) of the central fire gas inlet pipe (13), the he provision of the gap between the left gas inlet pipe (9) and the light cylinder part (152) of the left outer ring gas inlet pipe (15), and the he provision of the gap between the right gas inlet pipe (10) and the light cylinder part (162) of the right outer ring gas inlet pipe (16) improves the heat radiation performance.
