Abstract

LAVAVAJILLAS QUE COMPRENDE UNA VALVULA (7) QUE ESTA ABIERTA DURANTE LA FASE DE ENTRADA DE AGUA, Y UNA BOMBA DE CIRCULACION (11) A LA QUE SE SUMINISTRA ENERGIA DURANTE LA FASE DE ENTRADA DE AGUA. UN DISPOSITIVO DE CONTROL IMPULSADO POR UNA SEÑAL (V) QUE ES PROPORCIONAL A LA PRESION DE SALIDA DE LA BOMBA DE CIRCULACION, DE FORMA QUE CIERRE LA VALVULA DE ENTRADA (7) CUANDO LAS VARIACIONES DE LA SEÑAL DISMINUYAN POR DEBAJO DE UN VALOR PREDETERMINADO. LA BOMBA DE CIRCULACION (11) ES IMPULSADA POR UN MOTOR DE FASE SIMPLE ASINCRONA (14) CON UN CAPACITOR DE DESFASAJE (15) DESDE EL QUE SE DERIVA UNA SEÑAL (V). UN SEÑAL ADICIONAL (U) PUEDE DERIVARSE DEL CITADO CAPACITOR (15), PARA IMPULSAR EL DISPOSITIVO DE CONTROL, DE FORMA QUE SE DETERMINE LA CORRECTA DESCONEXION DE LA BOMBA DE DESCARGA (18).
