Embodiment Construction

[0044] As shown in the figure, the burner according to the present invention includes:

[0045] - the lower burner body 2 intended to be applied under the metal plate 48 of the cooktop and fixed to said metal plate 48 by eg screws 50,

[0046] - the first burner base 4 for the central flame ring integrated with the lower burner body 2,

[0047] - a second burner base 6 for one or two annular flame rings, conveniently constituted by a separate body from the first burner base 4,

[0048] - round cover 8 for first burner base 4,

[0049] - An annular cover 10 for the second burner base 6 .

[0050] Advantageously, the lower body 2 consists of a single part. Conveniently, it has an irregular shape but preferably has an outer edge inscribed in the circumference. Preferably, the lower body 2 has a shape in plan view that can be conceived to be produced by an almost circular shape but lacks two diametrically opposed circular segments at the edge 7 that reinforces the two opposed ...

Abstract

A multi flame-ring gas burner for cooktops. The multi flame-ring gas burner comprises: a lower burner body (2), which is applicable to the metal sheet (48) of a cooktop and arranged for the application of at least two injectors (60, 62) facing respective substantially horizontal, linear Venturi ducts (42, 44), also provided in said lower burner body (2); a first burner base (4) with a first circular cap (8) and with openings (30) for the release of a central flame ring; a second burner base (6) with a second annular cap (1 0) and with openings (72) for the release of at least one outer annularflame ring, said first and second burner bases (4, 6) being in fluid communication with the respective Venturi ducts (40, 42). The gas burner is characterized in that said lower burner body (2) is made in a single piece, wherein there are obtained: a seat for mounting a spark plug (32) intended to interact with said first burner base (4); two cylindrical seats (36, 38) having substantially horizontal and parallel axes, intended to accommodate two tubular elements (42, 44) internally shaped like linear Venturi ducts; and in a substantially central position and at the upper surface thereof, a substantially tubular portion (28) projecting upward, and in that: said first burner base (4) is integral with said projecting tubular portion (28) of said lower burner body (2), at least one injector-holder unit (52) provided with two portions (54, 56) is applicable to said lower burner body (2), the two portions (54, 56) are removably insertable into corresponding through holes (20, 22), and thethrough holes (20, 22) are obtained in said burner body (2) in a position facing said tubular elements (42, 44) internally shaped like linear Venturi ducts.

Description

technical field [0001] The present invention relates to a multi-flame ring gas burner for cooktops. Background technique [0002] Gas burners for cooktops with two or more main flame rings are known; these burners have an inner circular portion generating an inner flame ring and one or two flame rings (which are identical to the The flame ring generated by the inner circular portion is concentric) to the outer annular portion. [0003] Typically, burners of this type may have one or more injectors from which a flow of gas is released, the flow of which is controlled by a valve which is actuated by a user via a knob. [0004] In the case of a single injector or multiple injectors connected to a single outlet of a valve through which all flame rings are simultaneously regulated, and the burner is often referred to as a "multi-ring" burner. [0005] On the other hand, in the case of multiple injectors connected to two different outlets of the valve, the burner ring can be adj...
