Description
Technical Field
The present invention relates to the field of vacuum cleaners which allow the suction of dust and small-sized waste present on a surface to be cleaned, which may be, for example, a tile floor, a laminate, a mat or a carpet.
Background
A vacuum cleaner, more particularly a portable vacuum cleaner, comprises in a known manner: a waste separation device comprising an air outlet aperture; an inhalation device comprising an air inlet aperture and an electric ventilator; and a connecting tube fluidly connecting the air inlet aperture of the suction device to the air outlet aperture of the waste separation device. The electric ventilator is more specifically configured to generate an air flow through the air outlet aperture, the connecting tube and the air inlet aperture.
In such cleaners, the waste separating device typically extends substantially perpendicular to the axis of extension of the electric ventilator, and the end of the connecting tube oriented towards the waste separating device typically has a through-section that is substantially larger than the through-section of the air outlet aperture of the waste separating device.
This arrangement of the cleaner generates a large amount of turbulence in the connection pipe when the air flow generated by the electric ventilator flows in the connection pipe, and thus generates a high head loss in the connection pipe. However, these high head losses are very detrimental to the aerodynamic performance of the cleaner.
Disclosure of Invention
The present invention aims to overcome all or part of these disadvantages.
The technical problem underlying the present invention is in particular to provide a vacuum cleaner which is simple and economical in construction, while having improved aerodynamic properties.
To this end, the invention relates to a vacuum cleaner comprising: a waste separation device comprising an air outlet aperture; an inhalation device comprising an air inlet aperture and an electric ventilator; and a connecting tube fluidly connecting the air inlet aperture of the suction device to the air outlet aperture of the waste separation device, the electric ventilator being configured to generate an air flow through the air outlet aperture, the connecting tube and the air inlet aperture, characterized in that the connecting tube is curved and extends continuously from the air outlet aperture of the waste separation device to the air inlet aperture of the suction device.
This configuration of the connection tube limits the sudden change in the passage cross section that the air flow generated by the electric ventilator encounters when it flows between the waste separating device and the suction device, and thus greatly reduces the head loss that occurs in particular within the connection tube, which significantly improves the aerodynamic performance of the vacuum cleaner according to the invention.
The cleaner may also have one or more of the following features, alone or in combination.
According to one embodiment of the invention, the connecting tube has a through section which extends continuously from the air outlet aperture of the waste separating device to the air inlet aperture of the suction device. These arrangements ensure the continuity of the through-section encountered by the air flow as it flows from the waste separating device to the suction device, which further reduces the head loss generated in the connecting tube.

Fig. 1 to 7 show a vacuum cleaner 2, and more particularly a portable vacuum cleaner, the vacuum cleaner 2 comprising: a main body 3 provided with a grip handle 4, a waste separating device 5 removably mounted on the main body 3, and an inhalation device 6 accommodated in the main body 3.
The waste separating device 5 is advantageously cyclone-like and comprises, inter alia, a waste storage container 7 and a separating filter 8 accommodated in the waste storage container 7. The waste storage container 7 more specifically comprises an air inlet opening 9 and an air outlet aperture 11.
As shown in fig. 6, the inhalation device 6 comprises a motor housing 12 and an electric ventilator 13 provided in the motor housing 12, which electric ventilator 13 is also referred to as an inhalation motor.

Advantageously, the air outlet aperture 11 of the waste separating device 5 and the air inlet aperture 14 of the suction device 6 have different through-sections. According to the embodiment shown in fig. 1 to 7, the air outlet aperture 11 has a larger passage cross section than the air inlet aperture 14.
The cleaner 2 further comprises an energy storage element 10, such as a rechargeable battery, the energy storage element 10 being configured to supply power to the electric ventilator 13. The energy storage element 10 is advantageously housed in the body 3, for example in the grip handle 4.
The cleaner 2 further comprises a connecting pipe 16, which connecting pipe 16 fluidly connects the air inlet aperture 14 of the suction device 6 to the air outlet aperture 11 of the waste separating device 5. Advantageously, the connection tube 16 is integral.

As shown more particularly in fig. 6, the connecting tube 16 has a through section which extends continuously from the first end 16.1 to the second end 16.2 and thus from the air outlet aperture 11 of the waste separating device 5 to the air inlet aperture 14 of the suction device 6.
According to the embodiment shown in fig. 1 to 7, the connection tube 16 comprises a mounting portion 17, which mounting portion 17 extends around the first end 16.1 and which mounting portion 17 is fixed to the body 3, the connection tube 16 further comprises a fixing portion 18, which fixing portion 18 extends around the second end 16.2 and which fixing portion 18 is fixed to the motor housing 12 of the inhalation device 6.
The cleaner 2 further comprises a protective grille 19, which protective grille 19 is located upstream of the electric ventilator 13 to prevent a user from reaching the working part of the electric ventilator 13, especially when the waste separating device 5 is removed. According to the embodiment shown in fig. 1 to 7, the protective grille 19 is integrated in the motor housing 12 and is advantageously located at the air inlet aperture 14 of the inhalation device 6.
The body 3 further comprises an air suction conduit 21 and an air discharge conduit 22, the air inlet opening 9 of the waste separating device 5 being fluidly connected to the air suction conduit 21, the air discharge conduit 22 fluidly connecting the air pressure feed hole 15 of the suction device 6 to an air discharge opening 23 provided on the body 3.
The electric ventilator 13 is more specifically configured to generate an air flow through the air suction duct 21, the air outlet hole 11, the connection pipe 16 and the air inlet hole 14. The air flow generated by the electric ventilator 13 is discharged to the outside of the cleaner 2 via the air discharge duct 22 and the air discharge opening 23.
According to the embodiment shown in fig. 1 to 7, the air discharge duct 22 comprises a flow guiding element 24, which flow guiding element 24 is fixed to the motor housing 12, and to which flow guiding element 24 the air pressure feed hole 15 of the inhalation device 6 opens. The flow guiding element 24 is more specifically configured to channel and guide the air flow leaving the air pressure feed hole 15 to the air discharge opening 23.
Advantageously, the flow guiding element 24 comprises two side walls 25.1, 25.2 and a guiding wall 26, which guiding wall 26 connects the two side walls 25.1, 25.2 to each other. The guide wall 26 is curved and is located opposite the air pressure feed hole 15.
The flow guiding element 24 more particularly comprises an outlet opening 27, which outlet opening 27 is substantially perpendicular with respect to the second axis of extension B of the electric ventilator 13 and is oriented towards the air discharge opening 23.

The sound absorbing element 29 may be positioned downstream of the flow guiding element 24 or also in the flow guiding element 24. The sound absorbing element 29 is advantageously made of a porous material and may for example be an acoustic foam.
The operation of the cleaner 2 will now be described. When the electric ventilator 13 is powered, it establishes, in particular, a negative pressure in the waste separating device 5, so that air and waste are sucked in by the air suction duct 21. The waste-laden air then enters the waste storage container 7 via an air inlet opening 9, which air inlet opening 9 may for example open tangentially into the waste storage container 7. Thus, the air rotates and the waste is centrifuged to the outside, and the waste is collected by the waste storage container 7.
Then, the air flow continuously flows through the air outlet hole 11, the connection pipe 16 and the air inlet hole 14 of the inhalation device 6, and this does not cause a sudden change in cross section due to the specific configuration of the connection pipe 16. Accordingly, this configuration of the connection pipe significantly reduces the head loss generated within the connection pipe 16, which improves the aerodynamic performance of the cleaner 2.
The air flow then flows through the air pressure feed hole 15 and along the air discharge conduit 2 before escaping through the sound-absorbing element 29 in the direction of the discharge opening 23. The fact that the air discharge conduit 22 is formed in part by the flow directing element 24 significantly reduces the head loss generated downstream of the suction device 6, which further improves the aerodynamic performance of the cleaner 2.
Fig. 8 and 9 show a vacuum cleaner according to a second embodiment of the invention, which differs from the vacuum cleaner shown in fig. 1 to 7 mainly in that a protective grille 19 is integrated in the connecting tube 16 and is located near the second end 16.2 of the connecting tube 16.
Of course, the invention is in no way limited to the described and illustrated embodiments which are given by way of example only. Modifications can be made without departing from the scope of protection of the invention, in particular from the point of view of the construction of the various elements or by substitution of technical equivalents.
