GAS DOMESTIC PREMIXED VENTILATED HOB

WIPO Patent Application WO/2016/142770

A3

The object of the present invention is a ventilated hob (400) comprising a motor- driven fan (V) adapted to provide high pressure air to two or more burners (BRNi) thereof, each of said two or more burners (BRNi) at least comprising means (VG, 211; 211.a, 211.b) for supplying and regulating the flow of fuel gas (QGAS) in input into each of said two or more burners (BRNi), means (VP; 101; UG) for supplying the flow of combustion air (QAIR) in input into each of said two or more burners (BRNi), able to mix with said fuel gas, shut-off valves of the flow of said combustion air, an electronic unit (CMD) for controlling said air flow (QAIR). The air flow (QAIR) varies as a function of said flow of fuel gas (QGAS) in input into each of said two or more burners (BRNi) so as to ensure a gas-air mixture with a stoichiometric or substantially stoichiometric ratio without the need of input of secondary air from the outside, said variation of air flow (QAIR) being obtained by varying the pressure of the combustion air in said sealed circuit (CA1, 405, 407) inside said hob (400). Said pressure is intermediate to the single pressures that each active burner (BRNi) should have.
