摘要： 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.

摘要： A dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The dirt-laden fluid enters the chamber along a flow axis that intersects the disc.

摘要： A dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The disc comprises a perforated region and a non-perforated region. The holes are then formed in the perforated region, and the width of the non-perforated region is no less than the diameter of the inlet.

摘要： A dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The inlet is defined by an end of an inlet duct, and at least a portion of the inlet duct comprising the inlet extends within the chamber along an axis coincident the rotational axis.

摘要： A dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. A wall of the chamber is moveable between an open position and a closed position, and the inlet is defined by an end of an inlet duct attached to and moveable with the wall.

摘要： 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.

摘要： 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.
