Gas burner for stove

Abstract

A cooktop panel having a throughgoing main mounting hole and upper and lower faces has a burner having a holder underneath the panel, engaging the lower face at the hole, and provided with a gas inlet and a gas nozzle and a burner head mainly above the panel, engaging the upper face at the hole, and forming a downwardly extending intake passage into which the nozzle can feed gas. Fasteners engaged through the panel between the holder and the head retain the holder and head against the respective lower and upper faces. A burner cover atop the burner head forms therewith an annular gas-distribution chamber comunicating with the passage and forms with the burner head an annular array of outlet openings. This cover in formed with an upwardly projecting rack-centering collar defining a central seat. A rack atop the cover is formed centrally with a centering pin engaged in the seat. The holder is formed with a radially projecting mounting arm in turn formed with at least one vertically through-going igniter hole. An igniter engaged in the igniter hole projects through the panel to immediately adjacent the array of outlet openings. The main mounting hole is of a predetermined large diameter or a predetermined small diameter. The holder is formed with an upwardly extending collar fitting in the hole and having a lower large-diameter step corresponding to the predetermined large diameter and an upper small-diameter step corresponding to the predetermined small diameter.
