Definitions

  • This invention relates to a vacuum cleaner comprising a vacuum cleaner housing with a vacuum source, an inlet for dust-laden air communicating with the vacuum source, and a separation system for particles separated from the airflow that is placed after the inlet as seen in the airflow direction.
  • the separated particles are generally collected in a bag of a mainly airtight material.
  • cyclone vacuum cleaners have appeared on the market. They are designed such that the dust particles are separated from the airflow by means of centrifugal separation. The dust particles are collected in a rigid container which, when emptied, is removed from the vacuum cleaner and transported to a dustbin. This is cumbersome as well as dirty work, since a large amount of the dust sticks to the wall of the container and has to be removed by manual effort.
  • the container also surrounds vital parts of the cyclone arrangement and manual efforts are necessary in order to remove the interior parts of the container before cleaning the container. This manual work causes dust to spread to the surroundings when the container is emptied. Thus, the arrangement is very unhygienic.
  • WO 98/10691 discloses a vacuum cleaner including a disposable base.
  • the base includes a lower, rigid portion and an upper portion comprising a flexible sleeve, i.e. a flexible wall portion.
  • the base is sealable by twisting the base such that a part of the upper, flexible portion forms a tight neck.
  • This invention provides for a closing and/or a sealing effect of a dust bag by a closing and/or sealing means built into the vacuum cleaner. This enables a hygienic removal procedure for the bag as well as hygienic handling of the bag. Thus, the bag can be removed, transported, and thrown into a dustbin without any spillage of dust.
  • the arrangement is preferably because there is no need to touch the bag before the bag is closed and/or sealed and subsequently removed from the container where the bag is placed in the vacuum cleaner.
  • a vacuum cleaner having a housing with a vacuum source, an inlet for dust-laden air communicating with the vacuum source, a separation system for particles separated from the air flow that is placed after the inlet as seen in the airflow direction, wherein the separated particles are collected in a bag of a mainly airtight material, and a closing and/or sealing arrangement by which the bag inserted into the vacuum cleaner is closed and/or sealed before the bag is removed from the vacuum cleaner,
  • the vacuum cleaner shown in Fig. 1 comprises a housing 10 enclosing a vacuum source 11, such as a motor-fan unit, and a separation part shaped as a cyclone separator 12 having an inlet 13 for dust-laden air.
  • the inlet 13 is connected via a tube 14 to a nozzle (not shown).
  • the cyclone separator 12 comprises a mainly cylindrical chamber 15 having a first and a second end wall 16 and 17, respectively.
  • the inlet 13 is arranged near the first end wall 16 and designed such that a tangential inflow of the dust-laden air is achieved.
  • the chamber 15 also has a peripheral particle outlet 19 for particles separated by the cyclone separator 12 and is placed close to the second end wall 17.
  • the particle outlet 19 ends in a removable, stiff collecting container 20 in which a dust container, in the form of a bag 21, is inserted.
  • the bag 21 is pulled through an opening 22 in a cover part 23 belonging to the collecting container 20 such that the particles passing the particle outlet 19 are collected in the bag.
  • the bag 21 preferably consists of an airtight material, such as plastic.
  • the container cover 23, which also comprises a cover plate 24 (not shown in detail), encloses a closing and sealing arrangement for the bag 21 such that the bag can first be closed and then be sealed before it is removed from the vacuum cleaner.
  • the vacuum cleaner includes two L-shaped clamping jaws 25, as shown in Figs. 2-4 .
  • Each L-shaped clamping jaw 25 is turnably arranged about a shaft 26, which is arranged beside the cover opening 22 of the container cover part 23.
  • Each clamping jaw 25 has a first leg 27 with a part extending outside the cover that can be acted on manually or by some type of automatic system for turning the clamping jaws 25 between the positions shown with the full lines and the dashed lines in Fig. 4 .
  • the tension spring 28 is positioned at the other side of said connecting line.
  • the clamping jaws 25 automatically take one of these positions.
  • the second legs 29 of the clamping jaws 25 are provided with a heating thread 30 on their sides facing towards one another.
  • the heating thread 30 extends between the two clamping jaws and at each side of them.
  • the heating thread is connected to an electric supply circuit 31 comprising one or several batteries 32 ( Fig. 2 ) or means for electric supply via the mains supply (not shown).
  • electrical control means such as switches, timers and so on, for controlling the sealing and/or closing arrangement.
  • the device according to Figs. 1-4 operates in the following way.
  • the motor-fan unit 11 When the motor-fan unit 11 is activated, dust-laden air will flow through the inlet 13 and circulate in the chamber 15.
  • the dust particles will be influenced by the centrifugal forces and be transported towards the second end wall 17 of the chamber 15 and towards the particle outlet 19, where the particles are thrown out through the cover opening 22 and into the bag 21 inserted through the cover opening 22.
  • cleaned air flows through the clear air outlet 18 and is transferred to atmosphere by means of the motor-fan unit 11.
  • the clamping jaws 25 take the position shown in Fig. 3 .
  • the collecting container 20 is removed together with the bag 21 and the container cover 23, after which the clamping jaws 25 are moved to take the position shown in Fig. 4 .
  • a switch 33 is engaged so that that the control circuit 31 supplies a suitable current flow from the battery 32, or some other current source, and the heating thread 30 heats to such a temperature that a welding seal is achieved at the plastic bag.
  • the clamping jaws 25 are moved back to the position shown in Fig. 3 , after which the container cover 23 is removed from the collecting container 20 such that the bag is lifted up from the collecting container 20, removed from the container cover 23, and transported to a dustbin without spillage.
  • a new bag is then inserted through the cover opening 22 and together with the container cover 23 is placed in the collecting container 20.
  • the closing and/or the sealing process can be partly or completely automated, for instance, by being connected to the removal of the collecting container 20 from the vacuum cleaner.
  • the bag can be sealed by manual methods, for instance, by tying up the extending part of the bag with clips, strings, or tape around the bag, or by using existing closing means on the bag for instance, so-called zippers or the like.
  • manual methods for instance, by tying up the extending part of the bag with clips, strings, or tape around the bag, or by using existing closing means on the bag for instance, so-called zippers or the like.
  • the sealing arrangement according to the embodiment shown in Fig. 5 has a container cover 23 that encloses a circular bottom plate 40 provided with a fixed clamping jaw 41 having several small openings or recesses 42 on one side of the cover opening 22.
  • a movable clamping jaw 43 At the other side of the cover opening 22, there is a movable clamping jaw 43, which by two arms 44 is turnably supported at two brackets 45 arranged on the bottom plate 40.
  • the movable clamping jaw 43 is provided with several projections 46, which are placed such that they will enter into the small recesses 42 when the movable clamping jaw 43 is turned to abut the fixed clamping jaw 41.
  • the last-mentioned device operates in the following way when the bag 21, which preferably is a plastic bag, is changed.
  • the collecting container 20 with the bag 21 is removed from the vacuum cleaner, after which the movable clamping jaw 43 is turned from the position shown in Fig. 5 to a position where it rests on the fixed clamping jaw 41 and an area around the bag opening is clamped between the two clamping jaws 41, 43. Further pressing forces of the movable clamping jaw 43 causes the projections 46 to stretch, penetrate, and/or deform the bag material when they enter into the recesses 42 such that the bag will be closed.
  • the upper part of the bag with the seal is then pulled out through the cover opening 22 and transported to a dustbin, after which a new bag is inserted through the cover opening 22 and together with the container cover 23 is placed in the collecting container 20.
  • the container cover 23 is provided with a rectangular bottom plate 50 having guides 51 on which a cassette 52 is slidably arranged.
  • the cassette 52 comprises a tape on a first roller 53 rotatably arranged on a first holder 54.

  • the closing arrangement shown in Figs. 7-10 might also, in a manner mentioned in association to the embodiment according to Figs. 1-4 , be completed with a sealing arrangement. It is possible with the embodiment shown in Figs. 7-10 to also desist from using a bag. An operator may instead collect the dust directly into the collecting container 20 and, in a hygienic manner, transport the closed collecting container 20 together with the cover part 23 to a dustbin. The cover part 23 may then be removed from the collecting container 20, after which the container can be emptied into the dustbin. It would also be possible to use an arrangement where the bag can be taken out from the collecting container before it is closed and/or sealed. This may occur as long as the communication between the interior of the bag and the particle outlet of the separation system is maintained such that particles in the dust bag do not escape outside the vacuum cleaner when forces are applied on the bag.
  • closing and sealing arrangement are primary intended to be used together with cyclone vacuum cleaners to seal airtight bags in the form of conventional plastic bags that are available on the marker.
  • the three last-mentioned embodiments may also be used with other bags, for example, paper bags.
  • the expression "closing arrangement” in this connection generally means a device for temporarily closing the bag opening to prevent dust particles from leaving through the bag opening under the initial period of the bag changing procedure.
  • the expression "sealing arrangement” generally means a device for permanently sealing of the bag opening such that the bag in a hygienic manner can be taken out of the collecting container and be moved to a dustbin or the like
