Le système de pulvérisation comprend une pompe de circulation (8), un tube de sortie d'eau (9), et une cavité annulaire (10) disposée à l'extrémité avant du tambour externe (2). La cavité annulaire (10) est pourvue d'un orifice de pulvérisation (101). La pompe de circulation (8) est disposée sur le corps de machine (1) ou le tambour externe (2). Un orifice d'entrée d'eau de la pompe de circulation (8) est relié au tambour externe (2), et un orifice de sortie d'eau de celle-ci est en communication avec la cavité annulaire (10) au moyen du tube de sortie d'eau (9). En fonctionnement, la pompe de circulation (8) pompe l'eau de lavage dans le tambour externe (2) vers la cavité annulaire (10), de telle sorte que l'eau de lavage est pulvérisée dans le tambour interne (3) au moyen de l'orifice de pulvérisation (101). L'appareil de lavage à chargement frontal et le système de pulvérisation de celui-ci présentent des structures simples et de faibles coûts de fabrication, et peuvent améliorer considérablement l'efficacité de lavage.
