Abstract
An apparatus for generating a vortex in a collection vessel of a vacuum cleaner, using a blade assembly rotatably mountable in the collection vessel. By rotating the blade assembly, a vortex is generated inside the collection vessel, and enough suction is created to draw air through the entire system. The use of a blade assembly to generate the vortex may remove the need for an impeller external to the collection vessel, as the blade assembly may be capable of creating enough suction to draw air into the collection vessel. This may allow the vacuum cleaner to operate with lower noise.
Claims17
An apparatus comprising:
- a collection vessel having therein a motor having a driving gear,
- a support member, and
- a blade assembly rotatably mounted in the collection vessel and including
- a driven gear, and
- a plurality of blades mounted to the support member, wherein
- the plurality of blades extends downwards from the support member to be spaced apart from one another in a circumferential direction of the blade assembly,
- the plurality of blades is rotated by the driven gear of the blade assembly engaged with the driving gear of the motor, to thereby generate a suction force and a vortex within the collection vessel,
- the collection vessel has an air inlet and an air outlet,
- the air inlet is configured to direct suctioned air and particles from a surface external to the apparatus into the collection vessel through the suction force generated by the blade assembly, and
- the air outlet is configured to direct the suctioned air out of the collection vessel through the blade assembly using the vortex generated by the blade assembly and
- the plurality of blades is movable relative to the support member.
A vacuum cleaner comprising:
- a collection vessel having therein a motor having a driving gear,
- a support member, and
- a blade assembly rotatably mounted in the collection vessel and including
- a driven gear, and
- a plurality of blades mounted to the support member, wherein
- the plurality of blades extend downwards from the support member to be spaced apart from one another in a circumferential direction of the blade assembly,
- the plurality of blades are rotated the driven gear of the blade assembly engaged with the driving gear of the motor, to thereby generate a suction force and a vortex within the collection vessel,
- the collection vessel has an air inlet and an air outlet,
- the air inlet is configured to direct suctioned air and particles from a surface external to the vacuum cleaner into the collection vessel through the suction force generated by the blade assembly, and
- the air outlet is configured to direct the suctioned air out of the collection vessel through the blade assembly using the vortex generated by the blade assembly, and
- wherein the support member has a central aperture, and the vacuum cleaner further comprises a filter above the central aperture arranged to remove fine particles from air exiting the collection vessel.
