Abstract

SE PRESENTA UN APARATO PARA CONSERVAR ALIMENTOS, CON RETENCION DE CALOR, AUTORREGULADOR DE LA TEMPERATURA (10) QUE INCLUYE UN CUERPO (12), UN NUCLEO DE RETENCION DEL CALOR (14) Y UN ELEMENTO DE CALENTAMIENTO DE INDUCCION MAGNETICA (16). EL CUERPO (12) INCLUYE UNA PARED DE CONTACTO CON LOS ALIMENTOS (18), CALENTABLE, BASICAMENTE RIGIDA QUE DEFINE UNA CAVIDAD (24). EL NUCLEO (14) SE SITUA EN LA CAVIDAD (24), Y EN CONTACTO TERMICO CON LA PARED (18) PARA EL CALENTAMIENTO SELECTIVO DE LA PARED (18). EL NUCLEO (14) INCLUYE UN MATERIAL DE CAMBIO DE FASE DE ESTADO SOLIDO PARA ALMACENAR EL CALOR LATENTE DURANTE LA TRANSFORMACION DE FASE DE SOLIDO A SOLIDO A UNA TEMPERATURA DE TRANSFORMACION DE FASE. UN MATERIAL ELASTICO ESTA EN CONTACTO CON EL MATERIAL DE CAMBIO DE FASE PARA PERMITIR LA EXPANSION DEL MATERIAL DE CAMBIO DE FASE DURANTE LA TRANSFORMACION DE FASE. EL ELEMENTO CALENTADOR (16) ESTA EN CONTACTO TERMICO CON EL NUCLEO (14) PARA CALENTAR EL NUCLEO HASTA UNA TEMPERATURA POR ENCIMA DE LA TEMPERATURA DE TRANSFORMACION DE FASE PARA EFECTUAR UNA TRANSFORMACION DE FASE EN EL MATERIAL DE CAMBIO DE FASE. EL ELEMENTO (16) INCLUYE UN MATERIAL FERROMAGNETICO SENSIBLE A UN CAMPO MAGNETICO PARA INDUCIR UNA CORRIENTE ELECTRICA EN EL ELEMENTO (16) PARA CALENTAR EL ELEMENTO (16). UN MATERIAL FERROMAGNETICO TIENE TEMPERATURA DE CURIE ENTRE LA TEMPERATURA DE TRANSFORMACION DE FASE Y LA TEMPERATURA DE FUSION DEL MATERIAL DE CAMBIO DE FASE. UN DISPOSITIVO PARA EL CALENTAMIENTO DE LOS ALIMENTOS (42) INCLUYE UN CALENTADOR (44) QUE TIENE UN DISPOSITIVO DE SUJECION (46), UN GENERADOR DE CAMPO MAGNETICO (48) Y UN DETECTOR DE AUSENCIA DE CARGA (50), Y UN APARATO DE RETENCION DE LOS ALIMENTOS (10) SITUADO SOBRE EL DISPOSITIVO DE SUJECION (46).
