Problems solved by technology

Although it would be expected that the item would have been separated in the first cyclonic separation stage, it would be emptied out together with all the separated dust including the finer particles separated by the further separation stages
This small item is not easy to handle and can easily form a dust cloud

Embodiment Construction

[0022] Referring first to Figures 1 to 3, Figures 1 to 3 illustrate the dust container portion of a separation assembly according to the present invention. The separation assembly comprises: a first cyclone separation device for performing a first stage dust separation on the suction airflow drawn by the vacuum cleaner from any object to be swept; and at least one additional cyclone separation device for dust The airflow of the first cyclone is subjected to additional dust separation. As is well known, in cyclonic separating devices, the dust separated by the first cyclonic separating device and further cyclonic separating devices is retained in various parts of the dust container assembly.

[0023] The illustrated portion of the dust container assembly includes an outer housing wall 10 and an inner wall 12 that are generally cylindrical and define an annular space therebetween. A known cyclone stage structure has a first stage cyclone formed by the space between the walls 10...

Abstract

A cyclonic separator assembly for a vacuum cleaner, the assembly including a first cyclonic separator, formed by the space between the walls (10,12) for effecting a first stage of dust separation from the suction airflow of the cleaner, and at least one further cyclonic separator, within the wall (12), for further separation of dust from the air flow following the first separator, and a receptacle for separated dust, the receptacle including respective receiving portions for receiving dust separated by the first separator, within the wall (12), and the further separator(s), within the wall (12), wherein the respective portions of the dust receptacle are able to be emptied separately from one another.

Description

technical field [0001] The present invention relates to a cyclone type dust separation / collection device for a vacuum cleaner (suction sweeper). Background technique [0002] In the field of vacuum cleaners, so-called "cyclone" type separation devices have long been used to draw dust, dirt and other matter (herein referred to as "dust") from the suction airflow drawn by the vacuum cleaner from any object being cleaned. separated out. Cyclone vacuum cleaners can prevent or reduce the problem of clogged filters, which are used to separate dust prior to cyclone separators. Disposable or reusable bags are often used as the main separation filter for vacuum cleaners, wherein the dust separated by the air flow through the bag material remains in the bag for later disposal. [0003] The present invention relates more particularly to a cyclonic separation / collection assembly which utilizes a first cyclonic separation device to perform a first stage of separating dust from the suct...
