Abstract

SE DESCRIBE UN APARATO PARA CONTROLAR EL SUMINISTRO DE DETERGENTES LIQUIDOS EL LA CUBA DE UNA LAVADORA DE LAVANDERIA, ADAPTADO PARA DEPOSITAR UNA CONCENTRACION PRESELECCIONADA DE DETERGENTE EN EL AGUA ADMITIDA POR LA CUBA. EL APARATO CONSTA DE UN COMPARADOR ELECTRONICO (15) PARA COMPARAR UN VOLTAJE DE REFERENCIA PRESELECCIONADO GENERADO POR UN CIRCUITO DE CONTROL (21) AJUSTADO A UN VALOR CORRESPONDIENTE AL GRADO DE DUREZA DEL AGUA, CON EL VOLTAJE GENERADO POR UNO DE DOS CIRCUITOS INTEGRADOS (17,18), CADA UNO DE LOS CUALES TIENE UNA CONSTANTE DE TIEMPO DIFERENTE, SIENDO SELECCIONADO DICHO CIRCUITO INTEGRADO POR UN CONTACTO ELECTRICO (10) DE LA UNIDAD DE CONTROL PROGRAMADORA DEL TIEMPO (6) DE LA MAQUINA PARA ENERGIZAR O DESENERGIZAR UNA BOMBA MEDIDORA DE DETERGENTE LIQUIDO (12) MEDIANTE UNA FASE DE CONTROL (13) CONECTADA A DICHO COMPARADOR (15). TAMBIEN SE DESCRIBEN DOS DISEÑOS ALTERNATIVOS DEL INVENTO.
