Abstract

L'invention concerne un sèche-cheveux à faible bruit (100) qui comporte un boîtier (10), une bobine thermique (20), un moteur (30), un composant rotatif (40) et un silencieux (50). La bobine thermique (20), le moteur (30), le composant rotatif (40) et le silencieux (50) sont logés à l'intérieur du boîtier (10). Au moins une sortie d'air (11) et au moins une entrée d'air (12) sont respectivement disposées aux deux extrémités du boîtier externe (10). La bobine thermique (20) est placée sur un côté de ladite entrée d'air (11). La bobine thermique (20) et le moteur (30) sont fixés sur le boîtier (10). Le moteur (30) est connecté au composant rotatif (40). Le silencieux (50) est situé près de l'entrée d'air (12) du boîtier (10) et fixé sur le boîtier (10). Le sèche-cheveux à faible bruit (100) comprend en outre une zone de stabilisation de pression (70). La zone de stabilisation de pression (70) est située entre la bobine thermique (20) et le moteur (30) et est utilisée pour maintenir la pression d'air. Le silencieux (50) résout le problème du bruit fort et mélange uniformément l'air lorsque l'air traverse la zone de stabilisation de pression (70) pour maintenir la pression.
