Abstract:
1. A vacuum cleaner for dry dust, said vacuum cleaner comprising: a dust chamber having an air inlet opening and an air outlet opening; a fan unit arranged for producing an air flow from the air inlet opening to the air outlet opening and carrying the dry dust for collection in the dust chamber; a movable body supported in the dust chamber and arranged such that, in operation, said movable body rests on dry dust collected in the dust chamber due to kinematic sorting between the movable body and the dry dust and moves in a direction that increasingly restricts said air flow as the amount of dry dust in said dust chamber increases, kinematic sorting referring to a process whereby a mixture of larger and smaller objects is vibrated to effect sorting of said objects such that the larger objects become located above the smaller objects; said vacuum cleaner being adapted to effect vibration of at least one of the movable body and the dry dust chamber to produce said kinematic sorting.
