Abstract

filter system for a vacuum cleaner is disclosed. The system comprises a housing reconfigurable relative to a bin between an operative configuration in which the housing is disposed upon the bin so that dirt separated from dirt-laden air can collect in the bin, and an idle configuration in which the housing is removed from the bin. The housing comprises an inlet for receiving dirt-laden air into the housing, an outlet via which cleaned air can exit the housing. The system further comprises first filtering means and second filtering means disposed within the housing, the first filtering means being positioned upstream of the second filtering means. The first and second filtering means comprises a filter medium configured to separate dirt from the dirt-laden air passing from the inlet to the outlet through the filter medium. The system further comprises filter cleaning means for removing dirt from the filter medium of the first filtering means when the housing is configured at least in the operative configuration. The first filtering means comprising a panel comprising a first panel portion and a second panel portion. The filter cleaning means and driving means are configured to move the first panel portion or the second panel portion of the panel between a first position and a second position so as to agitate and remove the dirt deposited thereon.

Claims (21)

1. A filter system for a vacuum cleaner, the system comprising: a housing reconfigurable relative to a bin between an operative configuration in which the housing is disposed upon the bin so that dirt separated from dirt-laden air can collect in the bin, and an idle configuration in which the housing is removed from the bin, the housing comprising an inlet for receiving dirt-laden air into the housing, and an outlet via which cleaned air can exit the housing; the system further comprising: first filtering means and second filtering means, wherein the first and second filtering means are disposed within the housing, the first filtering means comprising a panel comprising a first panel portion and a second panel portion, the first filtering means being positioned upstream of the second filtering means, the first and second filtering means comprise a filter medium configured to separate dirt from dirt-laden air passing from the inlet to the outlet through the filter medium; filter cleaning means for removing dirt from the filter medium of the first filtering means when the housing is configured at least in the operative configuration, wherein the filter cleaning means comprise driving means configured to control and couple the filter cleaning means to the filter medium of the first filtering means, the driving means comprising a battery or an engine coupling, configured to power the driving means and wherein the filter cleaning means and driving means are configured to move the first panel portion or the second panel portion of the panel between a first position and a second position so as to agitate and remove the dirt deposited thereon.
2. The filter system according to claim 1, wherein the first filtering means comprise a panel having a plurality of apertures defining a mesh, the panel being adapted to cover at least a portion of an opening of the bin in the operative configuration of the housing.
3. The filter system according to claim 2, wherein the first panel portion and a second panel portion each comprise a respective port.
4. The filter system according to claim 3, wherein the first panel portion and the second panel portion are positioned substantially parallel to each other.
5. The filter system according to claims 3 or 4, wherein at least one panel portion is movable relative to the second panel portion between a first position in which the ports of the first panel portion and the second panel portion are substantially aligned to form a through- hole, and a second position in which the port in the first panel portion or the second panel portion is covered by at least a portion of the second panel portion or the first panel portion, respectively.
6. The filter system according to claim 1, wherein the filter cleaning means comprise a brush positioned adjacent the first or the second panel portion so that the movable panel portion moves in sliding contact with bristles of the brush to remove dirt from the filter medium.
7. The filter system according to any preceding claim, wherein the second filtering means comprise a cylindrical drum having a corrugated or concertina shape outer surface.
8. The filter system according to claim 7, wherein the drum comprises a channel which extends along a longitudinal axis of the drum and is fluidly coupled at one end thereof to the outlet of the housing.
9. The filter system according to claims 7 or 8, wherein the filter cleaning means comprises a protuberance configured to contact an outer surface of the drum.
10. The filter system according to claim 9, wherein the driving means is configured to rotate the drum about a or the longitudinal axis thereof, so that the protuberance contacts the outer surface of the drum upon rotation such that the dirt in the filter medium is agitated and can fall into the bin.
11. The filter system according to claim 10, wherein the driving means further comprises a plurality of elongated rollers positioned substantially parallel to each other and to the longitudinal axis of the drum such that the drum abuts the rollers, the driving means further comprising a driving belt coupled to the rollers so as to drive the rotation of the drum via the rotation of the rollers.
12. The filter system according to claim 10 or 11, wherein the driving means is further arranged to rotate the drum when the first panel portion and the second panel portion of the panel are in the first position thereby allowing at least a portion of the dirt to fall through an at least one through-hole into the bin.
13. The filter system according to any preceding claim, wherein the housing comprises spraying means adapted to spray the housing and/or an interior of the bin with a liquid so as to suppress the dust.
14. The filter system according to claim 13, wherein the spraying means is activated automatically upon reconfiguring the housing from the operative configuration into the idle configuration.
15. The filter system according to any preceding claim, wherein the driving means further comprise a switch or a timer configured to activate the driving means.
16. A vacuum cleaner, comprising: a ducting arrangement for communicating an air flow from an inlet to an outlet thereof; an impeller for creating an air flow along the ducting arrangement, and a bin for collecting dirt separated from the air flow; the filter system according to any preceding claim, the inlet and the outlet of the filter system being connectable within the ducting arrangement.
17. The vacuum cleaner according to claim 16, further comprising a chamber having an electromagnet, the chamber being positioned so as to allow air passing via the ducting arrangement to pass through the chamber, the electromagnet being configured to capture metal objects carried by the air through the chamber.
18. The vacuum cleaner according to claim 17, further comprising a receptacle arranged to receive metal objects.
19. The vacuum cleaner according to claims 16 to 18, further comprising a further filter disposed within the ducting arrangement.
20. The vacuum cleaner according to claims 16 to 19, further comprising a chassis having at least two wheels, the chassis being adapted to accommodate a wheelie bin.
21. The vacuum cleaner according to claims 16 to 20, wherein the impeller is operable to cause the air flow to flow in a forward and reverse direction along the ducting arrangement.
