However, these burners proved to be very complicated and bulky, and required removal of the upper metal plate of the cooking hob to adjust
[0006] FR2692014 describes a tube burner in which the injector is located at a considerable distance from the burner head; this is not suitable for mounting on a cooking hob and since it includes a large number of parts the assembly is rather complex and therefore costly Taller, which specifically consists of a flame divider head, a curved first pipe, a second pipe inside which houses the venturi pipe, two flanges and a U-shaped flange for supporting the injector

Embodiment Construction
[0020] From Figure 1-6 As can be seen, the figures show a particular multi-ring burner 2 applied to the upper metal sheet 3 of a conventional cooking hob, preferably of the built-in type, at positions corresponding to the holes provided therein.
[0021] The burner 2 has an inner circular distribution chamber 4 and an outer annular distribution chamber 6 to which a mixture of gas and primary air arrives, the primary air originating from two separate venturi ducts 8, 8', fed with the gas delivered by the respective injector 10, 10'. However, it should be understood that the type of burner, the number of flame rings, the number of injectors and the whole series of features recognizable in the burner illustrated in the drawings may also be different in the sense that the The burner is characterized by the way at least one venturi duct 8, 8' is adjusted relative to the injector 10, 10' located in front of it.
[0022] The venturi duct 8 is housed in the lower support structure ...

The invention relates to an improved gas burner for a cooking appliance, comprising: - a cup-shaped lower support structure (11, 12, 13) applied in a metal sheet (3) with a cooking hob In a position corresponding to the opening of - at least one injector (10, 10', 60, 62) having a substantially horizontal axis, which is applied to a first cavity provided in said support structure (11, 12) lateral walls (16, 31) of (14, 33, 35), - substantially horizontal at least one venturi duct (8, 8', 42, 44) connected to said injectors (10, 10', 60 , 62) are coaxial and open at their downstream ends into a second cavity (20, 20', 37) disposed in said support structure (11, 12, 13), is open upwards and is in fluid communication with at least one distribution chamber (6) for the combustion mixture to create at least one flame ring, characterized in that said venturi duct (8, 8', 42, 44) is formed with said The support structure (11, 12, 13) is composed of separate tubular elements and is accommodated so as to be able to perform free of axial movement and can be locked in a desired axial position by at least one locking member (28, 46), through which openings provided in the metal sheet (3) of the cooking hob can be accessed from the support structure (11, 12, 13) above access to the locking member.
Description
technical field [0001] The present invention relates to an improved gas burner for cooking appliances. Background technique [0002] Gas burners are known to have one or more primary flame rings, such as described in US2001 / 0010897, and are typically mounted on a cooktop; these typically include: a cup-shaped injector holder, at which the burner is mounted On cooking hobs; a burner body with one or more venturi ducts for mixing gas with primary air to form a combustion mixture; a flame divider with features for distributing the combustion mixture to create a flame One or more chambers of the ring, and upper closure caps for dispensing chambers. [0003] A range of burners with one or more main flame rings are available on the market, each user making an individual selection based on certain burner aspects and not others according to needs. [0004] Manufacturers of gas burners are often faced with the problem that in different countries and even in different regions of the...
