A kind of burner that is used for gas kitchen ranges
Technical field
The utility model relates to a kind of gas burner that is used for gas kitchen ranges.
Background technology
The development of gas-cooker is more and more paid attention to " keeping a public place clean "; The upper inlet wind type burner structure is with the performance of keeping a public place clean significantly, receives people and pays close attention to widely and approve.
Patent Office of the People's Republic of China announces that a utility model patent name is called: " gas-cooker that has inner spacer body "; The patent No.: CN02201626.0; The structure content of announcing is following: it comprises: at least two combustion gas furnace roofs, i.e. a center furnace roof and a plurality of peripheral furnace roof; A center mixing chamber; It has Venturi effect: a plurality of airducts that are used to get into original air; Get into the radially airduct in each peripheral furnace roof with a plurality of combustion gas/original air mixtures that make, described gas-cooker comprises a main body and a head, also comprises the inside partition member on a basic one-tenth plane; It is used to confirm to get into the upper surface and each lower surface of airduct radially of each airduct of original air, and the shape of described partition member is crosswise.
Above-mentioned structure exists weak point to be: described gas-cooker comprises that a shape is criss-cross partition member and a plurality of combustion gas and original air mixture of making gets into the radially airduct in each peripheral furnace roof; This has just caused not the keeping a public place clean property of this gas-cooker from overall structure; Soup juice, foreign material fall into end cup through axial auxiliary air air inlet die cavity probably, might stop up gas nozzle; This is just extremely asymmetric with " keeping a public place clean property " requirement of consumer's tight demand.
The burner upper-part of known prior art is made up of air distribution disk and separator sheet; Nozzles with injector is arranged on the air distribution disk; Separator sheet adopts steel plate to make; Just play the effect of parting seal combustion gas, air distribution disk and separator sheet need cooperate in outer shroud and center two circle riveted joints and guarantee its sealing; Need rivet cooperation to outer shroud and center two circles owing to add man-hour, so to the production profit that brings some inconvenience.
Summary of the invention
