Definitions

  • the present invention relates in general to a suction device, which is able to the removal of dust, soot and ash and which is usable, in particular, to keep clean fireplaces and stoves from residual of ash and soot accumulated in the brazier and/or at the surfaces that are in contact with the smoke trail of the above-mentioned heating devices.
  • the vacuum cleaners which are currently on the market cannot be used for cleaning and removal of ash, because the particles of dust and ash rapidly obstruct the protection of the motor, making unusable the vacuum cleaner after a few minutes of operation.
  • the motor is forced to work always under strain and consequently the average life time of the cleaner is notably reduced.
  • containers usually made of sheet metal and including a containment tank and a cover, which is usually connected on the outside walls of the tank through a metal ring closure.
  • Two ducts located at the relative holes, are normally placed on the cover, for the connection of respective flexible hoses, one of which is connected to a suction nozzle of ash and/or other waste materials in general, while the other flexible hose is connected to a suction unit.
  • the flexible hose which is connected to the suction nozzle can be made of fire-resistant plastic material or plastic material internally coated by a reinforced metal sheath, in order to avoid overheating due to the passage of ash and/or embers at high temperature, while the flexible hose connecting the suction unit to the metal container is usually made of plastic material and the suction nozzle is normally made of metallic material, such as aluminum.
  • An aim of the present invention is therefore to obviate to the above mentioned drawbacks and, in particular, to manufacture a suction device, in particular for the removal of ash, with a compact structure, at low costs and with additional functionality with respect to the prior art.
  • Another aim of the present invention is to make a suction device, in particular for the removal of ash, with a highly reliable operation, without having need of frequent and/or periodic maintenance.
  • a further aim of the invention is to manufacture a suction device, in particular for the removal of ash, which has a high average life time and which ensures high reliability, according to the operating and the electrical safety rules.
  • the suction device which is used particularly for the removal of ash, according to the present invention, includes a container or tank 10, which contains the aspirated ash and/or dust or soot and which is closed at the top by a removable cover 11, usually made of plastic material.
  • a shaped protruding insert 12 is made on the cover 11, so that said motor drive unit of the suction device is contained inside the insert 12 (the motor drive unit is therefore severally associated to the suction device) and has appropriate seats for the passage of the power cable 13 and for the insertion of one or more shaped buttons of activation and/or shutdown of the device; alternatively, the motor drive unit is not incorporated in the suction device according to the invention and the device uses an external suction unit as a drive unit ( fig. 7, 7A-7D, 8, 8A-8B ).
  • a single-stage dry motor is preferably used as a drive motor unit of the suction device and said motor, as shown in the above-mentioned figures, is firmly connected to the cover 11 of the suction device.
  • the inner surface 15 of the cover 11 is slightly convex and has an annular protruding edge 16, which falls within the lateral surface of the tank 10 and which corresponds to the throat ring 17 of the outer surface 18, slightly concave, of the cover 11.
  • the outer surface 18 of the cover 11 also has an annular edge 19, corresponding to a throat ring 20 of the inner surface 15 of the cover 11, in which the upper perimeter edge of the containment tank 10 is inserted, in order to obtain a stable coupling between the cover 11 and the tank 10, said tank 10 being made of sheet metal material or of plastic material.
  • one or more shaped fins 21 are provided along the annular edge 19, in order to allow the removal of the cover 11 and consequently the opening of the tank 10 containing the sucked waste, through a simple action of lifting of said fins.
  • the cover 11 is usually manufactured by molding and has two openings or holes 22, 23; the hole 22 is suitable for the insertion of a flexible hose (usually made of fire-resistant plastic material and/or reinforced by a internal metal sheath) which is connected to a suction nozzle (normally made of metallic material, such as aluminum) of ash, soot and dust in general.
  • a flexible hose usually made of fire-resistant plastic material and/or reinforced by a internal metal sheath
  • a suction nozzle normally made of metallic material, such as aluminum
  • the flexible hose which is connected to the suction nozzle, is inserted through the hole 22, at the shaped duct 24 placed on the outer surface 18 of the cover 11, so that the end of said hose counterbores the inner annular edge 25, while the hole 23, which is normally open, is surrounded by a circular duct 26, placed laterally with respect to the shaped protruding insert 12 and also provided with an inner counterbored annular edge 27.
  • the shaped duct 26, which is provided at the opening 23, is made of one single piece, usually by molding and together with the shaped protruding insert 12, thus constituting a lateral portion of said insert 12 (as shown in detail in Figure 5 ), while the duct 24 of the opening 22 is made directly on the cover 11.
  • a ring element 30A is inserted inside the opening 22; the ring element 30A has a screw or bayonet joint 31, which is able to engage within a conjugate profile 32 of the lateral wall 33 of the opening 22, so that the ring element 30A is hooked to the opening 22 of the surface 18 of the cover 11.
  • a filter whose external structure is indicated with 29 in Figure 4 , is placed at the shaped protruding insert 12, on the inner surface 15 of the cover 11.
  • the structure 29 of the filter can be bayonet-engaged on the base 28 of the drive motor of the suction device (as shown in Figure 4 ).
  • the structure 29 can be screwed on a threaded insert that is positioned beyond said base 28, in the vicinity of the inner surface 15 of the cover 11, or, according to other embodiments of the invention, the structure 29 of the filter is snap-jointed on a lid 30, which is in turn placed to cover the base 28 of the drive motor of the suction device (as shown in detail in Figure 4A ).
  • the structure 29 of the filter can be hooked to the cover 11, in the vicinity of the opening 23, through a screw or bayonet joint 38, which is inserted for rotation (arrow K of Figure 8B ), after being approached to the cover 11 (arrow J of Figure 8 ), into a conjugate shape provided inside the opening 23.
  • the support structure 29 of the filter is quickly, safely and simply removable and interchangeable, in order to carry out operations of cleaning or replacement by the user once the filter same is obstructed and/or unusable.
  • the structure of the filter can be advantageously made of epytropic and antistatic polyester fabric with medium calendering, and/or antistatic polyester felt with metal fibers and medium calendering; a protective metal mesh 40 can also be fixed, through sewing, to the filter fabric, in case of hot ash residuals fall in the filter (as schematically shown in the attached Figures 9-10 ).
  • the cover 11 can also be equipped with a knob 35, connected to a pin (made with a filet 36 or associated with a spring 37) extending inside the tank 10, which can be used as a filter-shaking system, by means of pulling the knob 35 according to the versus indicated by the arrow H of Figures 6C-6D and 7C-7D .
  • the suction device has an integrated motor drive unit or an external motor drive unit is used, it is possible to use the same flexible hose which is normally inserted (directly or through the screw and/or bayonet joint) in the hole 22 for aspirating waste ash from the filter and/or from other parts of the device, simply disengaging the hose from the hole 22 of the duct 24 and inserting said hose into the hole 23 (directly or through a screw and/or bayonet joint) of the duct 26, which is placed at the base 28 and at the structure 29 of the filter.
  • the suction device according to the invention allows a substantial reduction in the total costs, increasing the functionality, as the same suction device can be equally used for cleaning the filter and for cleaning other parts of the device.
  • the simple system of insertion and removal of the fittings and of the filter allows to make disengageable said fittings and said filter, with the consequent advantages relating to the possibility of simply clean, remove and/or replace the fittings and said filter, without having to replace the whole device or the whole containment tank once the filter is obstructed and/or unusable.
