Description
Technical Field
The present invention relates to the field of household cleaners, which allow the suction of dust and debris of small particle size present on the surface to be cleaned, which may be, for example, tiles (carrelage), floors (parquet), laminated materials (stratefie), woven cut pile carpets (motette) or carpets (tapis).
Background
As known, a household cleaner comprises:
-a main body containing a suction motor configured to generate an air flow through the cleaning head, the main body comprising at least one air discharge opening through which the air flow is discharged towards the exterior of the main body;
-a filtering device arranged in the main body upstream of the air discharge opening, the filtering device being configured to retain dust particles entrained by the air flow;
-a sound-absorbing element arranged in the body and covering the air outlet opening, the sound-absorbing element being realized in a porous material and comprising an outer surface abutting against the air outlet opening, and an inner surface facing towards the interior of the body; and
-an air duct defined in part by an inner surface of the sound absorbing element and in which an air flow flows, the air duct extending substantially parallel to the inner surface of the sound absorbing element, facilitating a majority of the air flow to flow along the inner surface of the sound absorbing element before exiting through the sound absorbing element towards an air exit opening.
The presence of such a sound-absorbing element at the air outlet opening allows to limit the noise generated by the household cleaner described above and to ensure satisfactory acoustic performance of the household cleaner.
The sound-absorbing member of such a household cleaner is more particularly arranged so that a portion of the sound-absorbing member protrudes in the air duct and disturbs the air flow flowing in the air duct. In particular, the sound-absorbing element reduces the passage cross-sectional area of the air flow in the air duct and generates turbulence (turbulences) in the air flow flowing in the air duct.
Therefore, such an arrangement of the sound-absorbing member has an adverse effect on the aerodynamic performance of the household cleaner.
Disclosure of Invention

According to the embodiment shown in the figures, the drainage wall 34 extends substantially parallel to the longitudinal axis of the suction motor 16.
The operation of the household cleaner 2 will now be described. When the suction motor 16 is energised, it creates a negative pressure in the waste separation and storage device 8 in particular, facilitating air and waste to be sucked in by the cleaning head 4. The air carrying the waste then enters the waste storage container 9 through the internal connecting duct 12 and the air inlet 13, the air inlet 13 opening tangentially into the waste storage container 9. The air is thus rotated and the waste is centrifuged towards the outside and a large part of this waste is collected by the waste storage container 9.
Small-sized dust, such as fine dust, which is not separated by the centrifugal force or held by the filtering separation portion 11, follows the air flow and then flows toward the suction motor 16 and the filtering device 27, and is held at the filtering device 27.
Subsequently, the air flow flows to the air duct 28 and along the inner surface 32.2 of the sound-absorbing member 32 before being discharged through the sound-absorbing member 32 towards the air discharge opening 29.
The particular arrangement of the sound-absorbing element 32 with respect to the drainage wall 34 allows not to disturb the air flow flowing in the air duct 28 and therefore allows to significantly limit the drag losses and the noise generated by the household cleaner 2. Therefore, the household cleaner 2 according to the present invention has improved aerodynamic and acoustic performance compared to the prior art household cleaner.
The invention is of course in no way limited to the described and illustrated embodiments, which are given by way of example only. Changes may be made, especially in matters of construction of different elements or by substitution of technical equivalents, without exceeding the scope of the invention. Thus, the household cleaner 2 can be a mopping type cleaner.
