Abstract

Conformément à des modes de réalisation, la présente invention concerne un dispositif de libération de détergent et un appareil de lavage. Le dispositif de libération de détergent comprend une boîte de distribution et une boîte à détergent, la boîte à détergent comportant un canal de mélange d'eau et un premier orifice d'évacuation d'eau, qui sont en communication l'un avec l'autre ; la boîte à détergent comportant un raccord d'eau de circulation ; le raccord d'eau de circulation comprenant un canal d'eau de circulation et un canal de réserve d'eau de circulation, qui sont en communication l'un avec l'autre ; une sortie du canal d'eau de circulation étant configurée pour guider un écoulement d'eau vers une entrée d'eau d'un filtre, et une entrée du canal d'eau de circulation étant configurée pour introduire l'eau de circulation ; et la position la plus élevée du canal de réserve d'eau de circulation étant plus élevée que la position la plus élevée du canal d'eau de circulation. Une pompe de circulation pompe l'eau, qui contient des flocs, au fond d'une cuve externe jusqu'à l'entrée du canal d'eau de circulation, et l'eau de circulation entre dans le filtre par le canal d'eau de circulation, de telle sorte que l'objectif de filtration circulaire des flocs est atteint ; et, lorsque le filtre est bloqué, la contre-pression au niveau d'une sortie d'eau du canal d'eau de circulation est augmentée, de telle sorte que l'eau de circulation est forcée de s'écouler vers le canal de réserve d'eau de circulation et est évacuée par le canal de réserve d'eau de circulation, permettant ainsi de réduire les probabilités d'explosion de tuyau, d'endommagement de la pompe de circulation et d'autres défauts causés par une augmentation rapide de la pression de l'eau.
