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.
  • a vacuum cleaner comprises in known manner a main body; a waste separation and storage device which includes a waste storage container removably mounted on the main body, the waste storage container being switchable between a use position and a removal position and comprising at least an air inlet configured to be connected in a sealed manner with a connecting duct carried by the main body when the waste storage container is in the use position; and a clamping device configured to clamp the waste storage container in the use position.
  • the clamping device comprises in particular elastic return means exerting pressure on the waste storage container when the waste storage container occupies the position of use.
  • Such a configuration of the clamping device, and in particular of the elastic return means makes the fluidic connection between an air inlet of the waste storage container and a connecting conduit which is carried by the main body and which is fluidically connected difficult to a suction head of the vacuum cleaner, which can substantially impair the sealing of the fluidic connection between the air inlet and the connecting duct and therefore the aeraulic performance of the vacuum cleaner.
  • the documents GB2440715A1 , US2004261213A1 and US2002108208 each disclose a vacuum cleaner comprising a main body, a storage container removably mounted on the main body, and a holding device configured to hold the waste storage container in the use position.
  • the present invention aims to remedy all or part of these drawbacks.
  • the technical problem underlying the invention consists in particular in providing a vacuum cleaner which is of simple and economical structure, while ensuring optimum sealing between the waste separation and storage device and the main body.
  • the present invention relates to a vacuum cleaner comprising a main body, and a waste separation and storage device which comprises a waste storage container removably mounted on the main body, the waste storage container being able to be tilted between a position of use and a position of removal and comprising at least one air inlet configured to be connected in a sealed manner with a connecting conduit carried by the main body when the waste storage container is in the position of use, the vacuum cleaner further comprising a clamping device configured to clamp the waste storage container in the use position, the clamping device comprising elastic return means exerting pressure on the waste storage container when the waste storage container occupies the use position, characterized in that the waste storage container s comprises at least one lateral stop which, when the waste storage container is moved towards the position of use, cooperates with the main body to form a pivot point about which the waste storage container pivots under the effect of the pressure exerted by the elastic return means so that the air inlet of the waste storage container is forced against the connecting duct.
  • Such a configuration of the clamping device and of the waste storage container ensures pivoting of the waste storage container when it is placed on the main body which tends to force the air inlet against the connecting duct, this which ensures optimal positioning of the air inlet relative to the connecting duct and optimal sealing of the fluidic connection between the air inlet and the connecting duct. This results in improved airflow performance for the vacuum cleaner according to this invention.
  • the stick vacuum cleaner may further have one or more of the following characteristics, taken alone or in combination.
  • the waste storage container is configured to tilt between the use position and the removal position about a tilting axis which is located above the waste storage container when the latter occupies the position of use.
  • the tilting axis is substantially horizontal when the vacuum cleaner is in a vertical position.
  • the waste storage container is configured to pivot, under the effect of the pressure exerted by the elastic return means, around a pivot axis which is transverse, and for example substantially perpendicular to the tilting axis.
  • the clamping device is configured to be placed under the waste storage container when the waste storage container occupies the position of use.
  • the pressure exerted by the elastic return means on the waste storage container is oriented upwards when the vacuum cleaner is in a vertical position.
  • the elastic return means comprise a clamping part which is movable between a clamping position in which the clamping part exerts pressure on the waste storage container and a release position in which the clamping piece allows tilting of the waste storage container towards the retracted position.
  • the clamping piece is mounted on the main body.
  • the clamping piece can for example be fixed to the main body, or be movably mounted on the latter.
  • the clamping part is fixed on the main body by fastening means, such as screws, allowing easy assembly and disassembly of the clamping part.
  • Such a characteristic has the advantage of facilitating the repairability of the product, in particular in the case of breakage of the clamping piece.
  • the clamping piece is elastically deformable between the clamping position and the release position.
  • the elastic return means are configured such that the clamping part is elastically biased towards the clamping position when it occupies the release position.
  • the waste storage container and the clamping piece are configured such that a tilting of the waste storage container from the position of use to the position of removal causes a displacement (and for example a deformation) of the clamping piece from the clamping position to the release position.
  • the waste storage container and the main body are configured such that, when the waste storage container is tilted towards the position of use, the lateral stop comes into abutment against the main body before the air inlet is forced against the connecting duct.
  • the clamping piece comprises a retaining part configured to cooperate with a mounting portion provided in a lower part of the waste storage container.
  • the retaining part has a shape complementary to the mounting portion.
  • the retaining part is curved and comprises a concave retaining surface configured to cooperate with the mounting portion.
