Definitions

  • the subject of the present invention is a vacuum cleaner which is dustproof, in the sense that it does not disperse the dust of the expelled air since the air is recirculated.
  • the vacuum cleaner comprises a special opening which takes in the dust/air mixture, a filter which retains and collects the dust, a turbine with radial/tangential discharge, a duct which conveys the discharge air to the output opening which injects the air into the suction region, and a dispenser for modifying the physical/chemical characteristics of the air without superfluous dispersal of additives into the atmosphere.
  • Figure 1 shows the principle of operation of the invention; the air and the dust are drawn in from the opening 1 and pass through the filter 2 which retains a large portion of the dust.
  • the filtering of the air can be coarse; this permits a considerable reduction in the power of the suction unit and hence in its consumption and noise.
  • the noise connected with the emerging air-flow is attenuated owing to the fact that the discharge air-flow is no longer admitted freely to the atmosphere.
  • the filter 2, which may be equipped with a dust-collection box 21, is cleaned periodically, manually or automatically, by the methods known in the prior art.
  • the expelled air is conveyed back into the region to be cleaned, provides the opportunity for the air to be treated by a device 5 which is constituted by any dispenser known in the art which enables the output air to be enriched with liquid or solid detergents and disinfectants, water, steam, ozone, foam, ions, heat, etc.
  • a device 5 which is constituted by any dispenser known in the art which enables the output air to be enriched with liquid or solid detergents and disinfectants, water, steam, ozone, foam, ions, heat, etc.
  • the motor 6 which drives the turbine 3 is not affected by the treated air but has its own independent cooling system.
  • Figures 2 and 3 show embodiments of the suction and output openings; before the compressed air is expelled into the working region, it undergoes a reduction in cross-section and, for the same air subsequently drawn in, the cross-section then increases progressively.
  • a large increase in the air speed is brought about in the same manner as in a Venturi tube and in the suction openings of currently available vacuum cleaners.
  • the suction duct, indicated 1 is the diverging portion of the Venturi tube which has its smallest cross-section in the dust-removal region, with the purpose of recovering the kinetic energy of the air-flow coming from the duct 4 which constitutes the converging portion; the diverging portion must be designed in a manner such as to favour the conversion of the kinetic energy into pressure energy with great efficiency in order thus to achieve energy and noise advantages.
  • Figure 4 shows another advantageous application of the invention and indicates, by way of example, a possible configuration of the suction and output openings which operate effectively on a battery-operated "robot" vacuum cleaner. This device takes advantage particularly of the reduction in power absorbed and in noise permitted by the invention.
  • the "robot” structure also helps to reduce flow resistance since it avoids the long hoses of the conventional structure. Moreover, the expulsion of air into the atmosphere is prevented according to the present invention; in practice, the "robot” vacuum cleaner takes in dusty air from the opening 1, conveys it directly, that is, without long connecting hoses, through the filter to the turbine and, from there, discharges it again directly, under pressure, from the opening 4 where it contributes to the exertion of a mechanical dirt-removal action. In practice, the details of construction may vary without, however, departing from the scope of the invention and hence from the scope of the patent of invention.
