Definitions

  • the present invention relates to the field of vacuum cleaners making it possible to suck up dust and small-particle waste present on a surface to be cleaned, which can for example be tiles, parquet, laminate, carpet or a rug.
  • waste separation device By waste separation device, reference is made to a separation device, for example of the filter type using at least one filter medium or cyclonic type using at least one cyclone, which is capable of separating waste and/or dust from the sucked air flow. Waste and/or dust are hereinafter referred to as waste.
  • the present invention aims to remedy all or part of the aforementioned drawbacks.
  • the technical problem underlying the invention consists in particular in providing a portable vacuum cleaner whose lightness and compactness are improved without, moreover, altering the robustness of the device and the performance of the vacuum cleaner.
  • the suction unit housing comprises a second wall which at least partially covers the first wall.
  • the second wall is formed at a distance from the first wall to define, at least in part, an internal space of the portable vacuum cleaner which extends between the first wall and the second wall.
  • the present invention makes it possible to provide an internal space to the portable vacuum cleaner which adjoins the suction unit.
  • This internal space is formed in the housing of the suction unit.
  • the walls of the housing of the suction unit make it possible both to form a protective housing around the suction unit and to create an internal space in the portable vacuum cleaner which is functional for the vacuum cleaner, that is to say an internal space which is intended to form an air duct or to receive a functional sub-assembly of the portable vacuum cleaner such as for example a noise attenuator or absorber, an electronic circuit board control or command of the portable vacuum cleaner or a filter forming part of the a Vogellic circuit, etc.
  • the portable vacuum cleaner may further have one or more of the following features, taken alone or in combination.
  • the first wall and the second wall of the suction unit casing are obtained by manufacturing in one piece.
  • the first wall and the second wall are for example obtained by injection under pressure of plastic material.
  • This feature has the effect of simplifying the manufacture of the suction unit housing.
  • the electric motor comprises an output shaft having an axis of rotation, the output shaft being coupled to the fan.
  • the first wall and the second wall are of partially annular shapes around the axis of rotation.
  • the first wall and the second wall then delimit an internal space of partially annular shape around the suction unit.
  • the internal space does not extend all around the suction unit.
  • the internal space could for example have a "C" shape which partially extends around the suction unit.
  • an internal space in the shape of a “C” makes it possible, for example, to provide more easily passages for electrical cables or passages for a Vogellic pipes which do not pass through the internal space.
  • This configuration therefore makes it possible to optimize the internal space in the presence of constraints such as, for example, passages of electrical cables or passages of a Vogellic pipes which cannot pass through the internal space.
  • first wall and the second wall are of annular shapes, for example tubular or tapered, substantially coaxial with the axis of rotation.
  • the first wall and the second wall then delimit, at least in part, an annular internal space which extends around the suction unit.
  • This configuration makes it possible to optimize the internal space that extends all around the suction unit. It is for example possible to place in this annular internal space a functional subassembly of large dimensions such as a dust filter while limiting the impact on the outer diameter of the portable vacuum cleaner.
  • the first wall and the second wall are connected by at least one connecting wall, the first wall, the second wall and the connecting wall are made in one piece, preferably in one piece obtained by plastic injection. Thanks to this configuration, the suction unit casing is simple to manufacture.

  • the chamber or duct is traversed by a flow of air generated by the suction unit when the portable vacuum cleaner is in operation.
  • the space internal form a pipe the latter is typically a ventilation pipe for conveying air in the portable vacuum cleaner.
  • the internal space forms a chamber the latter can be used to house a functional sub-assembly of the portable vacuum cleaner such as, for example, a filter, an attenuator or a noise absorber forming part of the a Vogellic circuit.
  • the internal space as defined can therefore carry out or receive functions essential to the portable vacuum cleaner.

  • the internal space is also adapted to receive a filter which belongs to an upstream part of the aunterlic circuit, that is to say upstream of the suction unit, the fact that the internal space is formed at side or around the suction unit makes it possible to further optimize the aeraulic circuit in terms of pressure drops and overall size when this internal space is used for a filtration chamber and a removable filter which belong to the downstream part of the aunterlic circuit, i.e. the part of the a Vogellic circuit which is located downstream of the suction unit.
  • the filtration chamber is delimited at least partially by the first wall, the second wall and the connecting wall.
  • the access opening allows installation or removal of the filter.
  • the filtration chamber and the filter have an annular shape which extends around the suction unit.

  • the internal space can therefore be formed with fewer walls than in a conventional vacuum cleaner, which makes it possible to further lighten the portable vacuum cleaner and to make it more compact.
  • This configuration also makes it possible to maximize the internal space between the protective casing of the suction unit and the vacuum cleaner housing.
  • the first wall and the second wall forming part of the same one-piece piece, the fact of forming the internal space between the protective casing of the suction unit and the vacuum cleaner housing does not alter the sturdiness of the portable vacuum cleaner at this location.
