Abstract

La présente invention concerne une machine à laver, comprenant une cuve de lavage destinée à contenir de l'eau dans le processus de lavage et un dispositif de collecte d'eau destiné à collecter l'eau d'écoulement de la cuve de lavage. Le dispositif de collecte d'eau comprend une cavité de collecte d'eau et un orifice de drainage en communication avec la cavité de collecte d'eau. Une pluralité d'orifices de drainage sont présents afin de satisfaire l'exigence de drainage de prévention de débordement du dispositif de collecte d'eau. La cuve de lavage de la machine à laver selon la présente invention est utilisée comme cuve de retenue d'eau, et aucune cuve extérieure n'est disposée à l'extérieur de la cuve de lavage. La présente invention fournit uniquement un dispositif de collecte d'eau au fond de la cuve de lavage. Dans ce cas, l'eau de lavage dans la cuve de lavage s'écoule vers le dispositif de collecte d'eau puis elle est évacuée. Par conséquent, le dispositif de collecte d'eau possède une cavité de collecte d'eau servant à accomplir la fonction de stockage temporaire d'eau. La présente invention comporte une pluralité d'orifices de drainage, qui peuvent augmenter l'écoulement d'eau du dispositif de collecte d'eau en temps unitaire en vue de réaliser un drainage rapide, réduisant ainsi l'eau accumulée dans un réservoir de collecte d'eau et empêchant le débordement du dispositif de collecte d'eau.
