Abstract

La machine à laver décrite a une structure permettant d'empêcher l'entrée d'eau dans un dispositif de production d'ozone (42). Dans la machine à laver, un tube d'introduction (43) s'allonge vers le bas à partir du dispositif de production d'ozone (42) et est branché à un élément de passage du flux d'air (31). De ce fait, même s'il se produit une condensation dans le tube d'introduction (43) par une différence de température entre l'intérieur et l'extérieur du tube d'introduction (43), les gouttes d'eau générées par la condensation tombent vers le bas par gravité en direction de l'élément de passage du flux d'air (31) et ne pénètrent pas dans le dispositif de production d'ozone (42). De plus, même si des bulles d'eau et des bulles de détergent se trouvant dans une cuve externe (7) au cours de l'opération de lavage pénètrent dans le tube d'introduction (43) et se transforment en gouttes d'eau lorsqu'elles éclatent, les gouttes d'eau tombent vers le bas par gravité en direction de l'élément de passage du flux d'air (31) et ne pénètrent pas dans le dispositif de production d'ozone (42) de la même façon que l'eau tombe par la condensation.
