摘要

A collection apparatus for use in vacuum cleaners appliance to collect sucked up materials includes a tank that has a bottom, peripheral walls and an upper opening opposite to the bottom, and that is adapted to be closed by a removable lid; suction means that are coupled to the tank to create a negative pressure therein; and separation means that separate the sucked up materials from the air flows moving in a suction direction defined from an inlet into the tank and an outlet from the tank, which are either wet separation means or dry separation means that can be alternately and interchangeably mounted within the tank using removable mounting means.

主权项

1. A collecting apparatus of sucked materials for vacuum cleaner appliances comprising:
a tank having a bottom, peripheral walls and one upper opening opposing said bottom and closable by a removable lid; sucking means coupled to said tank to create a negative pressure on an inside of said tank; and separating means of sucked material extracted from a sucked air flow in a sucking direction defined between an inlet into said tank and an outlet from said tank, wherein said separating means are selected from the group consisting of wet separating means and dry separating means, said wet separating means and dry separating means being configured to be alternatively and replaceably assembled within said tank with mounting means, wherein said separating means comprise: a channeling duct of said sucked air flow from outside into said tank according to said sucking direction; and a separating element between said sucked material and said sucked air flow arranged downstream of, and fluid-dynamically connected with, said channeling duct, and wherein said channeling duct comprises a siphon shaped duct having: a first inlet section configured to be coupled with said inlet obtained in said tank; a second outlet section facing said sucking means; and a third intermediate siphoning hairpin bended section fitted between said first inlet section and said second outlet section, wherein a connecting opening with said separating element is provided in said intermediate siphoning section.
