Abstract

La présente invention concerne un dispositif de nettoyage par ultrasons et un lave-linge. Le dispositif de nettoyage par ultrasons comprend : une cuve de nettoyage (1) destinée à contenir l'eau de lavage ; une unité de délivrance d'eau (2) destinée à délivrer l'eau à la cuve de nettoyage (1) ; une unité de mesure de niveau d'eau (4) destinée à mesurer le niveau de liquide dans la cuve de nettoyage (1), une extrémité de mesure de l'unité de mesure de niveau d'eau (4) s'étendant dans la cuve de nettoyage (1) ; et une structure de blocage d'eau (5) qui est disposée à l'intérieur de la cuve de nettoyage (1) et est utilisée pour empêcher l'eau délivrée par l'unité de délivrance d'eau (2) d'atteindre l'extrémité de mesure de l'unité de mesure de niveau d'eau (4). L'installation de la structure de blocage d'eau (5) sur la cuve de nettoyage (1) réduit la vitesse d'écoulement à laquelle un écoulement d'eau délivrée s'écoule vers l'extrémité de mesure de l'unité de mesure de niveau d'eau (4), ce qui empêche l'écoulement d'eau délivrée d'osciller jusqu'à déborder de la cuve de nettoyage (1) et évite l'imprécision d'un résultat de mesure de niveau de l'unité de mesure de niveau d'eau (4). Par conséquent, la présente invention garantit que le niveau de l'eau délivrée est précis et empêche l'eau délivrée dans la cuve de nettoyage (1) d'être insuffisante ou de déborder. De plus, la présente invention présente une structure simple et de faibles coûts.
