Abstract

L'invention concerne une machine à laver. La machine à laver comprend : un boîtier (1), une cuve de lavage (5) disposée dans le boîtier (1); un réservoir de lavage (3) disposé sur le corps (1); et un dispositif de génération d'ultrasons (2) disposé au-dessus du réservoir de lavage (3) et relié au boîtier (1). Une extrémité de vibration ultrasonore du dispositif de génération d'ultrasons (2) fait face au réservoir de lavage (3). Après avoir placé le vêtement à laver (4) entre le dispositif de génération d'ultrasons (2) et le réservoir de lavage (3), l'extrémité de vibration ultrasonore du dispositif de génération d'ultrasons (2) vient en contact partiel avec le vêtement à laver (4) et des ondes de vibration ultrasonores sont directement transmises au vêtement à laver (4) qui est imbibé d'un liquide de lavage (12) pour le lavage. La machine à laver est capable à la fois de nettoyer globalement un vêtement et d'éliminer rapidement de manière approfondie des taches tenaces sur des parties du vêtement. Comme l'extrémité de vibration ultrasonore du dispositif de génération d'ultrasons (2) entre directement en contact avec le vêtement imbibé à laver (4), la consommation d'ondes ultrasonores pour un vêtement souple peut être fortement réduite, l'effet des ondes ultrasonores peut être amélioré et les taches profondes sur le vêtement peuvent être amenées en résonance, ce qui permet d'accomplir l'objectif d'élimination plus approfondie des taches.
