Abstract
A floor care appliance such as a vacuum cleaner is provided having an filtration bag changing assembly located in the filtration compartment. A supply of filtration material is packaged in a container in the form of a continuous tube to be fed into the filtration compartment. A sealing and cutting assembly seals the tube at the lower end after a bag is fed into the filtration compartment. Once a filtration bag is full, a new filtration bag is pulled into place with the lower end of the tube being sealed and the old filtration bag being cut from the tube by a cutter. A pair of opposing heating elements are used to seal the opposing sidewalls of the tube together to form the filtration bag. The free end of the tube is fluidly connected to the suction nozzle by a connector and a dirt duct.
Claims7
A particle collecting and filtration system for a floor care appliance having at least a suction nozzle, a motor-fan assembly for generating a dirt laden airstream originating at the suction nozzle, a filtration compartment, and a suction duct, the particle collecting and filtration system comprising:
- a container having an open end separated from a closed end by a sidewall;
- a connector having a first end and a second end, wherein said connector extends through said closed end of said container;
- a filtration media formed into a tube and having a portion thereof compressed into the container between the open end and closed end thereof, wherein said tube has a first end and a second end wherein the first end is attached to the container and said second end is initially sealed so that a volume is formed within a portion of said tube for filtering and collecting particles from said dirt laden airstream, wherein said second end of said connector resides within said volume, and said container, said connector, and said filtration media form an independent element that is selectively placed in the filtration compartment and selectively fluidly connected to the suction duct through said first end of said connector.
