Abstract

ESTA INVENCION SE REFIERE A UN HERVIDOR DE GAS PARA MONTAR SOBRE LA PARED, UTIL PARA EL EMPLEO DOMESTICO, DE UN TIPO QUE COMPRENDE UN QUEMADOR DE PREMEZCLA (13), UN INTERCAMBIADOR DE CALOR (12), UN CIRCUITO (8) PARA PERMITIR CIRCULAR AL AIRE DE COMBUSTION, MECANISMOS (5) QUE CAUSAN DICHA CIRCULACION DE AIRE, UNA CAMARA (18) PARA MEZCLAR EL AIRE CON EL GAS, LA CUAL TIENE UNA APERTURA (19) CORRIENTE ARRIBA DE DICHA CAMARA DE MEZCLA (18) EN EL CIRCUITO (8), PARA LA CIRCULACION DEL AIRE, ESTANDO DICHA APERTURA CERRADA MEDIANTE VALVULAS (20), Y PERMITIENDO A LA DISOLUCION DE AIRE FLUIR A TRAVES DE LAS APERTURAS (21) SIN LLEGAR A SER MEZCLADAS CON EL GAS HASTA EL PUNTO CORRESPONDIENTE A LA CAMARA DE MEZCLA (18); ESTA TAMBIEN PROVISTO CON MECANISMOS (22, 23 Y 24) PARA CAMBIAR LA CANTIDAD DE GAS INTRODUCIDA EN PROPORCION AL INDICE DE FLUJO DEL AIRE QUE FLUYE A TRAVES DEL MISMO. EL HERVIDOR DE ACUERDO CON ESTA INVENCION PUEDE ESTAR TAMBIEN PROVISTO CON UN CONTENEDOR DE UNA SOLA PIEZA (2), TENIENDO UNA CAMARA INTERIOR PRESURIZADA (9), DENTRO DE LA CUAL AMBOS, EL QUEMADOR (13) Y EL INTERCAMBIADOR DE CALOR (12) ESTAN DISPUESTOS, Y UNA CAMARA EXTERIOR DESPRESURIZADA (8) A TRAVES DE LA CUAL EL AIRE SUCCIONADO EN SU INTERIOR POR MEDIO DEL EXTRACTOR (5) FLUYE; LA DESEMBOCADURA DE LOS HUMOS DE LA CAMARA INTERIOR (9) Y LA ENTRADA DE AIRE A LA CAMARA EXTERIOR (8) DISCURRE A TRAVES DE UN CONDUCTO COAXIAL SUPERIOR (14); TAMBIEN TIENE UN MIEMBRO DE CIERRE (3) DEL CONTENEDOR, ESTANDO PROVISTO DICHO MIEMBRO CON UN DOBLE OBTURADOR PARA CERRAR ESTRECHAMENTE TANTO LA CAMARA INTERIOR (9) COMO LA CAMARA EXTERIOR (8); Y UNA ROSCA ARQUIMEDEA INFERIOR (4) DENTRO DE LA CUAL EL EXTRACTOR (5) ESTA ALOJADO.THIS INVENTION REFERS TO A GAS KETTLE FOR WALL MOUNTING, USEFUL FOR HOUSEHOLD USE, OF A TYPE INCLUDING A PREMIX BURNER (13), A HEAT EXCHANGER (12), A CIRCUIT (8) TO ALLOW CIRCULAR TO COMBUSTION AIR, MECHANISMS (5) THAT CAUSE SUCH AIR CIRCULATION, A CHAMBER (18) TO MIX AIR WITH GAS, WHICH HAS AN OPENING (19) ABOVE SUCH MIXING CHAMBER (18) IN THE CIRCUIT (8), FOR THE CIRCULATION OF THE AIR, WHICH IS SUCH A CLOSED OPENING THROUGH VALVES (20), AND ALLOWING THE DISSOLUTION OF AIR TO FLOW THROUGH THE OPENINGS (21) WITHOUT GETTING MIXED WITH THE GAS TO THE POINT CORRESPONDING TO THE MIXING CHAMBER (18); IT IS ALSO PROVIDED WITH MECHANISMS (22, 23 AND 24) TO CHANGE THE AMOUNT OF GAS INTRODUCED IN PROPORTION TO THE INDEX OF AIR FLOW THAT FLOWS THROUGH THE SAME. THE KETTLE ACCORDING TO THIS INVENTION MAY ALSO BE PROVIDED WITH A SINGLE PIECE CONTAINER (2), HAVING A PRESSURIZED INTERIOR CHAMBER (9), WITHIN WHICH BOTH, THE BURNER (13) AND THE HEAT EXCHANGER (12) THEY ARE ARRANGED, AND A DEPRESSURIZED EXTERNAL CHAMBER (8) THROUGH WHICH THE SUCTIONED AIR INSIDE THEM BY THE EXTRACTOR (5) FLOWS; THE OUTLET OF THE SMOKE FROM THE INTERNAL CHAMBER (9) AND THE ENTRANCE OF AIR TO THE EXTERNAL CHAMBER (8) GOES THROUGH A SUPERIOR COAXIAL DUCT (14); IT ALSO HAS A CLOSING MEMBER (3) OF THE CONTAINER, SUCH MEMBER IS PROVIDED WITH A DOUBLE SHUTTER TO CLOSE CLOSELY BOTH THE INTERIOR CHAMBER (9) AND THE EXTERNAL CHAMBER (8); AND A LOWER ARCHIMEDAL THREAD (4) INSIDE WHICH THE EXTRACTOR (5) IS STAYED.
