Abstract

La présente invention concerne une unité principale d'un dispositif de nettoyage, et un dispositif de nettoyage. L'unité principale comprend un boîtier, un ventilateur et un couvercle de ventilateur, le boîtier étant pourvu d'une entrée d'air de boîtier et d'une sortie d'air de boîtier ; le ventilateur est disposé dans le boîtier ; le couvercle de ventilateur est disposé dans le boîtier et est pourvu d'une cavité de montage, d'une entrée d'air de couvercle de ventilateur et d'une sortie d'air de couvercle de ventilateur, à la fois l'entrée d'air de couvercle de ventilateur et la sortie d'air de couvercle de ventilateur sont en communication avec la cavité de montage, au moins une partie d'un moteur électrique est disposée dans la cavité de montage, et lorsque le moteur électrique fonctionne, de l'air est aspiré à partir de l'entrée d'air de couvercle de ventilateur et est évacué vers la sortie d'air de couvercle de ventilateur ; et une cavité d'admission d'air et un canal d'échappement sont formés entre le boîtier et le couvercle de ventilateur, à la fois l'entrée d'air de boîtier et l'entrée d'air de couvercle de ventilateur sont en communication avec la cavité d'admission d'air, et à la fois la sortie d'air de boîtier et la sortie d'air de couvercle de ventilateur sont en communication avec le canal d'échappement. Grâce au couvercle de ventilateur, un canal d'écoulement d'air de refroidissement du moteur électrique est défini, et un écoulement d'air entrant dans le boîtier circule le long du trajet susmentionné, de façon à circuler autour du moteur électrique de manière plus concentrée, améliorant ainsi l'effet de refroidissement de l'écoulement d'air sur le moteur électrique.
