ADDITIONAL PRIMARY AIR SUPPLY FOR COOKTOP GAS BURNERS

摘要

A gas burner unit for a cooktop (12) having a spreader (30) with a plurality of gas outlets (34) above the top surface (16) of the cooktop (12). A venturi (36) is in fluid communication with the gas outlets (34). An orifice holder (38) secures a gas orifice (40) in position in a main body (44) of the orifice holder (38) and has a plurality of protrusions (52) extending upwardly and defining a plurality of upwardly directed primary air inlets (90). The plurality of primary air inlets (90) are in fluid communication with the main body (44) of the orifice holder (38), and the main body (44) is in fluid communication with the venturi (36). A general primary air inlet behind one or more of the control knobs of the cooktop (12) allows ambient air to enter the area (24) below the cooktop (12) which is in fluid communication with the main body (44) and the venturi (36).
