  • Publication number: 20200359865
    Abstract: A dirt separator for a vacuum cleaner including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate about a rotational axis and including holes through which the cleansed fluid passes. The disc includes a first region in which a first array of said holes is provided, and a second region, radially outward of the first region, in which a second array of said holes is provided. Each hole of the second array has a larger cross-sectional area than each hole of the first array.

  • Publication number: 20200214522
    Abstract: A dirt separator for a vacuum cleaner including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate about a rotational axis, and including holes running from an upstream face to a downstream face through which the cleansed fluid passes. Each hole has a tapered portion which narrows from an upstream end to a downstream end thereof.

  • Publication number: 20200170464
    Abstract: A dirt separator for a vacuum cleaner including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate about a rotational axis and including holes through which the cleansed fluid passes. When viewed normal to the disc, each hole is elongate and defines a longitudinal axis which runs within the plane of the disc. The longitudinal axis of each hole is inclined relative to the radial direction of the disc.

  • Publication number: 20200163510
    Abstract: A dirt separator for a vacuum cleaner including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate in a predetermined direction about a rotational axis, and including holes running from an upstream face to a downstream face through which the cleansed fluid passes. When viewed along the radial direction of the disc, the path of each hole through the thickness of the disc defines a centreline, the centreline being inclined such that it is non-perpendicular to the disc. The centreline of each hole is inclined such that it intersects the upstream face of the disc at a point which is behind, in the direction of rotation of the disc, the point at which the centreline intersects the downstream face of the disc.

  • Publication number: 20200163509
    Abstract: A dirt separator including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber, and a disc located at the outlet, the disc being arranged to rotate about a rotational axis and including holes through which the cleansed fluid passes. The holes are distributed over at least first and second regions of the disc, the second region being radially outward of the first region. The porosity of the second region is higher than the porosity of the first region.
