Abstract

La présente invention se rapporte au domaine technique des machines à laver et concerne spécifiquement une machine à laver à air frais, visant à résoudre le problème d'un mauvais effet de ventilation à l'intérieur des machines à laver existantes. À cet effet, la machine à laver à air frais selon la présente invention comprend un corps de boîte, et un corps de tambour et un ensemble ventilateur montés dans le corps de boîte ; la machine à laver à air frais comprend en outre un système d'air frais utilisé pour compléter l'apport d'air frais dans le corps de tambour ; une entrée d'air et une sortie d'air sont formées dans le corps de boîte ; le système d'air frais complète l'apport d'air frais dans le corps de tambour au moyen de l'entrée d'air et évacue l'air dans le corps de tambour au moyen de la sortie d'air ; la sortie d'air et l'entrée d'air sont agencées de manière adjacente ; et la sortie d'air et l'entrée d'air sont à un angle ouvert de l'intérieur vers l'extérieur. Un flux d'air à humidité élevée s'écoulant hors de la sortie d'air s'écoule vers une direction distante de l'entrée d'air, l'air frais est pompé au niveau de l'entrée d'air à partir d'une direction distante de la sortie d'air et le flux d'air au niveau de l'entrée d'air est distant du flux d'air au niveau de la sortie d'air, de telle sorte que l'air à humidité élevée s'écoulant hors de la sortie d'air puisse être empêché d'entrer à nouveau dans le corps de tambour au moyen de l'entrée d'air, ce qui permet d'améliorer l'effet d'air frais du système d'air frais.
