Definitions

  • Embodiments described here concern a vacuum cleaner device, preferably for domestic use, in particular a vacuum cleaner device of the electric sweeper type, that is, without a canister.
  • the vacuum cleaner device according to the invention allows a user to have a wide versatility of use, even for long periods, in complete safety.
  • Embodiments described here also concern a functioning method of the vacuum cleaner device.
  • Vacuum cleaner devices which comprise a collection container and a motor unit which generates a suction flow to suck up and draw material, that is, dust and dirt, into the collection container, a handle by which the user can grasp and maneuver the vacuum cleaner device, or at least part of it, and a power supply unit, which supplies electrical energy to the suction unit.
  • vacuum cleaner devices can also comprise a suction head which, during use, comes into contact with the surface to be cleaned and which can be connected to the collection container by means of a suction pipe.
  • Known vacuum cleaner devices are mainly divided into two categories, that is, traditional canister-type vacuum cleaner devices and vacuum cleaner devices of the electric sweeper type.
  • Canister-type vacuum cleaner devices comprise a slider, possibly provided with wheels or other means, to facilitate movement, on which the collection container and the motor unit are disposed, while the handle can possibly be associated with a rigid or flexible suction pipe.
  • the collection container, the motor unit and the handle define a suction unit that can be used by itself by means of suitable accessories, or connected by means of a suction pipe to the suction head, in such a way as to assume a conformation similar to a traditional sweeper.
  • the motor unit and the collection container are therefore positioned in correspondence with the handle, so that most of the weight of the vacuum cleaner device must be supported by the user's arm.
  • Canister-type vacuum cleaner devices are normally powered by an electric cable able to be connected to the domestic electrical network.
  • This type of device can be inconvenient and difficult to maneuver, especially if one wants to reach hard-to-clean surfaces such as, for example, the tops of cupboards, or if the space to be cleaned is rather restricted, or does not have easily accessible electric sockets.
  • these canister-type vacuum cleaner devices require a cooling circuit suitable to prevent overheating of the electronics associated with the power supply of the motor unit.
  • Vacuum cleaner devices of the electric sweeper type do not normally have cables and the power supply unit consists of a rechargeable battery pack.
  • cordless vacuum cleaners One disadvantage of cordless vacuum cleaners is that the autonomy of the battery that powers them may not be fully compatible with the duration requirements desired by the user.
  • One known solution to this problem is to provide, together with the vacuum cleaner device, an additional and interchangeable battery pack.
  • Another disadvantage is that, by supplying two battery packs together with the vacuum cleaner device, the production costs, and consequently the sales costs, are considerably higher than for the solution with a single battery pack.
  • One purpose of the present invention is to provide a vacuum cleaner device which combines the advantages of both types of known vacuum cleaner devices, also overcoming their respective limits.
  • one purpose of the present invention is to provide a vacuum cleaner device which is manageable and easy to use and which guarantees an autonomy of use not restricted to a limited period of time.
  • Another purpose of the present invention is to provide a vacuum cleaner device which allows a longer time of use, even when it is functioning at maximum power, compared with known devices.
  • Another purpose of the present invention is to provide a vacuum cleaner device which guarantees the safety of the user who uses it, even in the event of prolonged use.
  • Another purpose of the present invention is to provide a vacuum cleaner device with improved reliability and cooling capacity when necessary.
  • Another purpose of the present invention is to provide a vacuum cleaner device which allows to increase its useful life, requiring fewer maintenance interventions.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • the present invention concerns a vacuum cleaner device, in particular of the domestic type, comprising a suction unit provided with a collection container and a motor unit configured to draw a flow of air and dirt from the outside and convey it toward the collection container, and a handle unit connected to the suction unit and configured to allow gripping by a user.
  • the vacuum cleaner device comprises at least one power supply unit suitable to supply electrical energy to the suction unit.
  • the vacuum cleaner device comprises a housing seating provided with holding means able to house and hold, by means of a selective and reversible coupling, the at least one power supply unit.
  • the housing seating is comprised in the handle unit of the vacuum cleaner device.
  • the vacuum cleaner device comprises two power supply units, in particular a battery power unit and an electric cable power unit, which are interchangeable one with each other and able to be alternatively inserted in the housing seating.
  • both power supply units comprise coupling means able to cooperate with the coupling means provided in the compartment, or housing seating, of the vacuum cleaner device so as to guarantee a stable reciprocal coupling between the power supply unit and the suction unit.
  • the coupling means can also comprise, in addition to mechanical holding and attachment means, mating electrical connectors suitable to transfer the electrical energy from the respective power supply unit to the electronics of the suction unit.
  • the coupling as above is of the mechanical type, for example interlocking, and is reversible and repeatable, that is, the power supply unit and the vacuum cleaner device can be decoupled and coupled repeatedly.
  • the user can use the battery power unit when having to operate in environments without electrical sockets, or in conditions in which the electric cable is a hindrance, while the user can use the electric cable power unit when requiring a greater autonomy of use than that provided by the battery power unit, or when this is not charged.
  • This solution advantageously allows to quickly and easily replace the cable power unit in place of the battery power unit when the latter is not charged, and continue with the cleaning operations without having to wait for the battery to recharge, or provide a spare one.
  • This embodiment also allows to adapt the cable power unit even to already existing vacuum cleaner devices of the electric sweeper type, coupling it to the already existing coupling means.
  • the suction unit comprises a containing shell which defines a suction chamber, inside which the motor unit is positioned, which is put in fluidic communication with the collection container.
  • the containing shell is provided with outlet means, for example a plurality of holes, or through slits, through which the air drawn by the suction unit and filtered in the collection container is returned to the outside.
  • outlet means for example a plurality of holes, or through slits, through which the air drawn by the suction unit and filtered in the collection container is returned to the outside.
  • the containing body is provided with a through hole suitable to put the inside of the suction chamber in communication with the outside in the proximity of the housing seating of the handle unit.
  • each power supply unit comprises an external container defining a housing compartment in which the electrical and/or electronic components are contained and housed.
  • At least the cable power unit, and possibly also the battery one comprises at least one inlet aperture and an outlet aperture made in the shell and configured to allow the passage of air from the external environment toward the inside, so as to cool the electrical and/or electronic components contained therein.
  • the outlet aperture of the cable power unit when it is positioned in the housing seating, is disposed in a mating position and cooperates with the through hole provided in the suction unit.
  • the internal volume of the power supply unit is therefore fluidly connected to the suction chamber of the suction unit.
  • the motor unit can generate a cooling flow that conveys a flow of clean air taken from the external environment, inside the power supply unit and from this toward the suction chamber, from which it will be evacuated back into the external environment through the outlet means.
  • the vacuum cleaner device directly utilizes the clean air of the external environment to cool the cable power unit, or possibly also the battery one, thus avoiding the use, for cooling, of the air exiting from the collection container.
  • this vacuum cleaner device does not require additional mechanical filters in the cooling circuit of the cable power unit, or possibly even the battery one, thus lowering production costs.
  • This solution also allows to produce the vacuum cleaner device in a simple way, using the same motor unit both to draw the air and dirt to be conveyed into the collection container, and to draw the cooling air.
  • a shutter member for example a valve, associated with the through hole and able to selectively allow or not allow the passage of the cooling air through it between the power supply unit and the suction chamber.
  • the shutter member is of the normally closed type, that is, it keeps the hole closed if not subjected to external stress.
  • the cable power unit can be provided with a drive member suitable to stimulate the shutter member, taking it to the open condition and thus allowing the opening of the through hole and the passage of air.
  • This solution allows to advantageously keep the through hole closed when the battery power unit is used, so as to prevent possible load losses due to the drawing of the cooling air, while ensuring its functioning when the cable power unit is used.
