Definitions

  • the said control unit being particularly large, is generally arranged in a service room, or outside in a sheltered location, also because of the noise, that, even though is moderate, proves to be anyway annoying inside a dwelling-house.
  • the aim of the present invention is to provide a control unit for vacuum cleaner systems, which is more practical than the control units currently used, in terms of reduction of overall dimensions, of simplicity and reversibility of the installation, and of comfort of use.
  • a further aim of the invention is to effectively reduce the noise, without using bulky and anaesthetic silencer means, arranged outside the control unit.
  • the control unit comprises a central body or stage 4, provided with an input duct 500 of the suctioned air.
  • the stage 4 is closed on the upper side by a sort of lid or head stage 9, which bears an output duct 901 of the filtered air and a control panel 903, which serves as user interface.
  • the stage 4 is provided on the lower side with a container 1, for collecting the dust, which is equipped with a sort of funnel 104, designed for fastening a suitable bag to collect the dust.
  • the funnel 104 is rimmed by a washer 105, pressed between the container 1 below, and the superposed central stage 4.
  • the said container 1 is provided with a rapid hooking and releasing means to the central stage 4, in order to be easily removed and inserted through simple frontal movements by a single operator, manually and without making use of tools.
  • a shackle 3 nearly semicircular-shaped, is hinged on its seats 301, externally of the central stage 4 on the respective seats 401, so that by pushing a release button 102 ( FIG. 6, 7, 8, 9, and 10 ), steadily arranged on the dust container 1 in a suitable frontal seat 101 and clasping from below with a hooked portion 103 a suitable protrusion 302 of the shackle 3, the release of the said protrusion 302 allows the container 1 to remain hung under the shackle 3.
  • the shackle 3 is arranged tilted, by turning upon the pivots 301 and 401, by means of a couple of cylindrical protrusions 300, which engage respective notches 100, suitably realized on the outer surface of the container 1.
  • the container 1 can be seized with both hands and easily removed to replace the dust bag, that is, besides, provided with a suitable tensioning means.
  • the control unit according to the invention allows to limit the noise, thanks to the fact that the motor unit -fan wheel 7 is not tighten with screw means to the central stage 4, as in the usual control units, but it is simply locked, being interposed between a couple of vibration-proof rubber gaskets 700 and 701.
  • the gasket 701 that is the upper one, shaped to be locked by matching suitable notches of the motor 7, is reversible, in order to fit two sizes of the motor.
  • the size of the motor being definitely small, give the control unit a compact design and small overall dimensions.
  • a silencer 8 which is arranged, inside the head stage 9, by means of a plurality of notches, realized on its base, matching respective protrusions realized on the gasket 701.
  • the air coming from the motor 7 below is forced to pass inside the silencer 8, which is labyrinth-shaped and completely covered with sound absorbent material, for example foam polyurethane.
  • the air goes through a convoluted course inside the silencer, then it comes out directly into the output duct 901.
  • the silencer is characterized in that its input and output ducts do not directly face each other, in order to perform the aimed reduction of the noise intensity.
  • the said silencer 8 comprises a container 800, preferably made of ABS and realized by injection moulding, which is closed by a lid 840 and it bears, stuck on its inside, a base 810, a sort of labyrinth-shaped duct 820 and a closing element made of sound absorbent material.
  • Two openings 801, 802 are realized on opposite lateral sides of the container 800, and are suitable to be arranged respectively by the input and the output of the air.
  • a further feature of the claimed control unit is that it can fit different conditions of the system to serve, being preset so that it allows to choose under way the side from which the suctioned air enters and the side from which the filtered air exits, independently one from each other.
  • the input of the suctioned air takes place, at the central stage 4, through a duct 500, which protrudes from an end of an element 5, which is fixed by screw means to the said central stage in correspondence with two suitable openings 402 ( fig. 12 ), arranged symmetrically with respect to the vertical median plane of the central unit.
  • the element 5 is perfectly reversible, because it allows to obtain the input of the air from each openings 402, by simply arranging it with its duct 500 matching the chosen opening.
  • the head stage 9 can be adapted to allow the exit from one or from the other side, by inverting the position of two lateral bulkheads 900 and 902, one of them (900) being provided with the output duct 901, to be arranged by the output 802 of the silencer 8, suitably rotated for this purpose when it is fixed inside the head stage 9.
  • the control unit is fixed to the wall, by pre-assembling a suitable support 6 onto the wall, and then applying the control unit to the support by way of a simple frontal push, and by the fastening of suitable protrusions 501, projecting from the element 5 from the opposite side with respect to the side to be fixed to the central stage 4.
  • the protrusions 501 are fastened into respective holds 601 realized on the support 6, and they can be released simply by pushing two lateral tabs 602.
  • the said frontal fastening system allows positioning the control unit in a small place, or even in a built-in box, because it does not require any lateral or vertical movements, to mount or to remove the control unit.
  • the air filter 200 inside the control unit can be easily installed and removed since it is supported by a ring 201, screwed on the lower end of the central portion 403 of the central stage 4.
  • the filter 400 is protected by a coaxial cylindrical shield 404, which extends toward the bottom in order to intercept any possible dangerous objects dragged with the suctioned air.
  • the invention also provides that the control unit can be equipped with a self-cleaning unit of the filter 200 ( fig. 11, 12, 13 ).
  • the self-cleaning unit comprises a compressor 210, which fills a storage tank 211 with compressed air until a known electric valve commands the opening of a fast discharging valve 213, when a prearranged pressure level is reached, measured by a manostat 212.
  • the opening of the valve 213 determines the immediate inflow of a stream of air inside the filter 200 through a nozzle 214.
  • the stream of air has opposite direction with respect to the filtering direction, so that it causes the removal of the particles retained inside the filter.
  • the said self-cleaning unit which operates with a rate that can be set as required, is arranged between the vibration-proof gasket 700 of the motor 7 and the filter 200 below, and it is protected externally by a case 2.
  • the case 2 is realized so that it can be interposed between the central stage 4 and the head stage 9, in order to maintain the small overall dimensions of the control units, and it has a central duct 20 for the necessary passing of the suctioned air.
