Description

Broom type dust collector

Technical Field

The present invention relates to the field of broom-type cleaners allowing 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 carpet or a carpet.

Background

A broom-type cleaner comprises, in a known manner: the system includes a handle, a cleaner head configured to contact a floor surface to be cleaned, a body disposed between the handle and the cleaner head, and a waste separation and storage device removably mounted to the body.

The waste separation and storage device includes, inter alia, a waste storage container and a connecting conduit including an air inlet opening configured to be fluidly connected to the suction head and an air outlet opening leading to an interior of the waste storage container. The connecting conduit is secured to the outer surface of the waste storage container, for example by ultrasonic welding.

This configuration of the waste separation and storage device significantly increases the manufacturing costs of the waste separation and storage device and thus of the broom.

Disclosure of Invention

The present invention aims to overcome all or part of these disadvantages.

The technical problem on which the present invention is based is, in particular, to provide a broom-type vacuum cleaner that is simple and economical in construction.

To this end, the invention relates to a broom-type vacuum cleaner comprising: a handle, a suction head configured to come into contact with a ground surface to be cleaned, a body disposed between the handle and the suction head, and a waste separation and storage device removably mounted on the body, characterized in that the body comprises a first half-shell and a second half-shell assembled to each other and defining an internal connection conduit configured to fluidly connect the suction head to an air inlet of the waste separation and storage device, and the body further comprises a sealing joint disposed between the first and second half-shells to seal the internal connection conduit.

This configuration of the broom cleaner, in particular of the main body, allows to realise the internal connection duct which directly connects the suction head to the waste separation and storage device by assembling the first and second half-shells, thus eliminating the need to fix additional components on the waste storage container. Thereby significantly reducing the manufacturing costs of the broom-type cleaner according to the present invention.

The broom-type cleaner may also have one or more of the following features, used alone or in combination.

According to one embodiment of the invention, the first and second half-shells are each made of plastic.

According to one embodiment of the invention, the first and second half-shells are assembled to each other along their periphery.

According to one embodiment of the invention, said sealing joint extends substantially parallel to an assembly plane of said first and second half-shells.

According to one embodiment of the invention, the waste separation and storage device comprises a waste storage container comprising an air inlet.

According to one embodiment of the invention, said internal connection duct comprises a first duct portion extending substantially parallel to the longitudinal axis of said handle of said broom cleaner and a second duct portion extending transverse and for example substantially perpendicular to the longitudinal axis of said handle of said broom cleaner.

According to one embodiment of the invention, the support rib and the duct wall at least partially overlap. In other words, at least a portion of the support rib is located opposite the outer wall surface of the conduit wall. This configuration of the supporting ribs and the duct walls avoids hard waste, such as toothpicks, from being inserted between the supporting ribs and the duct walls and subsequent hair or other waste from being retained by these hard waste in the internal connecting duct and thus ultimately impairing the suction performance of the broom.

According to one embodiment of the invention, the duct wall has a height greater than the height of the support rib.

According to an embodiment of the invention, the first half shell further comprises a counter support rib extending from a groove bottom of the receiving groove, the sealing joint abutting against the counter support rib.

The handle 4 comprises in particular a grip 6 at its upper end.

The broom cleaner 2 further comprises a waste separating and storing device 7, which waste separating and storing device 7 is removably mounted on the main body 3 so as to be able to be cleaned. The waste separating and storing device 7 comprises, in particular, a waste storage container 8 and a separating filter (not shown in the figures) housed in the waste storage container 8. The waste storage container 8 is more specifically housed in a housing receptacle 9 defined by the main body 3.

The main body 3 comprises in particular an internal connection duct 11 (see figure 4), which internal connection duct 11 is configured to fluidly connect the suction head 5 to an air inlet 12 provided on the waste storage container 8. The internal connecting duct 11 comprises in particular an air outlet opening 13, which air outlet opening 13 is located opposite the air inlet 12 and which is fluidly connected to the air inlet 12.

According to the embodiment shown in the figures, the internal connection duct 11 comprises a first duct portion 11.1 and a second duct portion 11.2, the first duct portion 11.1 extending substantially parallel to the longitudinal axis of the handle 4, the second duct portion 11.2 extending transversely and for example substantially perpendicular to the longitudinal axis of the handle 4.

As shown in figure 3, the main body 3 houses an inhalation device 14, which inhalation device 14 comprises a motor housing 15 and an inhalation motor 16, also called an electric ventilator, which inhalation motor 16 is arranged in the motor housing 15 and is configured to generate an air flow through the suction head 5 and the internal connecting duct 11. The suction device 14 is more particularly arranged in an internal housing 17 defined by the main body 3.

In a known manner, the suction motor 16 comprises a ventilator and an electric motor configured to drive the ventilator in rotation. According to the embodiment shown in the figures, the longitudinal axis of the suction motor 16 is substantially parallel to the longitudinal axis of the handle 4.

Advantageously, broom cleaner 2 further comprises a rechargeable battery (not shown in the figures) configured to power suction motor 16. The rechargeable battery may be housed in the body 3 or in the handle 4.

As more specifically shown in fig. 6, the motor case 15 includes a support 18 and a fairing 19, the support 18 being configured to support the suction motor 16, the fairing 19 being assembled to the support 18 and covering the suction motor 16. The motor housing 15 also comprises a through opening (not shown in the figures) provided on the support 18 and fluidly connected to the waste separation and storage device 7.

As shown in fig. 6, the streamline portion 19 includes an air outlet 21 and a protective grill 22, and the protective grill 22 is located between the air outlet 21 and the suction motor 16. These arrangements allow preventing the user from touching the working parts (features actives) of the suction motor 16 housed in the motor housing 15.

The broom-type cleaner 2 further comprises a filter device 23, which filter device 23 is arranged in the main body 3 downstream of the suction motor 16. Advantageously, the filtering device 23 is mounted on the motor casing 15 and, more specifically, on the streamlined portion 19. According to the embodiment shown in the figures, the filter device 23 rests against the protective screen 22.

The suction motor 16 is more specifically configured so that the generated air flow flows through the through opening provided on the support 18 and the air outlet 21, and the filter device 23 is configured to retain the dust particles conveyed by the air flow escaping through the air outlet 21.

As shown in fig. 4, the main body 3 further includes an air flow pipe 24 and discharge openings 25 (see fig. 2), the air flow pipe 24 being located downstream of the filter device 23, and the air flow generated by the suction motor 16 being used for circulation in the air flow pipe 24, the air flow being discharged to the outside of the main body 3 through the discharge openings 25. Advantageously, the discharge outlet 25 is oriented towards the waste separation and storage device 7.

As shown more specifically in fig. 4, the main body 3 and the waste separation and storage device 7 delimit a space 26, the discharge opening 25 opens into this space 26, and the air flow discharged to the outside of the main body 3 circulates through this space 26.

The broom-type cleaner 2 further comprises a sound-absorbing member 27, which sound-absorbing member 27 is arranged in the main body 3 to cover the discharge opening 25. The sound-absorbing element 27 is advantageously made of a porous material and may for example be an acoustic foam. The sound-absorbing element 27 comprises a first surface 27.1, which first surface 27.1 rests against the discharge opening 25, and a second surface 27.2, which second surface 27.2 is oriented towards the inside of the body 3.

As shown more particularly in fig. 4, the airflow duct 24 is partially delimited by the body 3 and by a second surface 27.2 of the acoustic absorption element 27. Advantageously, the air flow duct 24 extends parallel to the second surface 27.2 of the sound-absorbing element 27, so that a major part of the air flow generated by the suction motor 16 circulates along the second surface 27.2 of the sound-absorbing element 27 before escaping past the sound-absorbing element 27 in the direction of the discharge opening 25.

As shown in fig. 2 and 3, the main body 3 comprises a first half-shell 3.1 and a second half-shell 3.2, the first half-shell 3.1 and the second half-shell 3.2 being assembled to each other, for example by screwing or snapping, and the first half-shell 3.1 and the second half-shell 3.2 more particularly defining the internal connection duct 11, the internal housing 17 and the air flow duct 24. The first and second half-shells 3.1, 3.2 are assembled to each other, for example along their periphery.

The body 3 further comprises a sealing joint 28, which sealing joint 28 is arranged between the first and second half-shells 3.1, 3.2 to seal the internal connecting duct 11. The sealing joint 28 extends substantially parallel to the assembly plane of the first and second half-shells 3.1, 3.2.

The sealing joint 28 more particularly extends along at least a longitudinal wall of the inner connecting duct 11, but the sealing joint 28 may also extend along one or more transverse walls of the inner connecting duct 11.

Advantageously, the first half-shell 3.1 comprises a housing groove 29, the housing groove 29 extending along the internal connection duct 11 and the sealing joint 28 being housed in the housing groove 29, and the second half-shell 3.2 comprises a supporting rib 31, the supporting rib 31 extending along the internal connection duct 11 and being configured to compress the sealing joint 28 housed in the housing groove 29. According to the embodiment shown in the figures, the receiving groove 29 and the support rib 31 each extend continuously along the internal connection duct 11, in particular along the longitudinal wall of the internal connection duct 11. However, the receiving groove 29 and the support rib 31 may each discontinuously extend along the inner connecting duct 11.

According to the embodiment shown in the figures, the first half-shell 3.1 further comprises a duct wall 32, the duct wall 32 comprising an inner wall surface 32.1 and an outer wall surface 32.2, the inner wall surface 32.1 laterally delimiting the internal connection duct 11, the outer wall surface 32.2 being opposite the inner wall surface 32.1. Advantageously, the duct wall 32 has a height greater than the height of the support rib 31, so that the support rib 31 and the duct wall 32 at least partially overlap.

According to the embodiment shown in the figures, the entire supporting rib 31 is located opposite the outer wall surface 32.2 of the duct wall 32, so that the internal connecting duct 11 is only laterally delimited by the duct wall 32.

The first half-shell 3.1 further comprises a retaining rib 33, which retaining rib 33 extends along the outer wall surface 32.2 of the duct wall 32, such that the duct wall 32 and the retaining rib 33 delimit the receiving groove 29. This configuration of the first and second half-shells 3.1, 3.2 ensures improved compression of the sealing nipple 28 and thus improved sealing of the internal connecting duct 11.

According to the embodiment shown in the figures, the first half-shell 3.1 further comprises a counter support rib 34, which counter support rib 34 extends from the groove bottom of the receiving groove 29. The sealing joint 28 thus abuts against the counter-bearing rib 34 and is clamped between the counter-bearing rib 34 and the bearing rib 31. However, the main body 3 may not be provided with such a counterpart support rib 34.

According to the embodiment shown in the figures, the front and rear walls of the internal connection duct 11 are defined by a first bottom wall 35 and by a second bottom wall 36, respectively provided on the first and second half-shells 3.1, 3.2.

The operation of the broom-type cleaner 2 will now be described. When the suction motor 16 is powered, it creates a negative pressure, in particular in the waste separation and storage device 7, so that air and waste are sucked in by the suction head 5. The waste laden air then enters the waste storage container 8 via the internal connecting conduit 11 and the air inlet 12, which air inlet 12 opens tangentially into the waste storage container 8. The air is thus rotated and the waste is centrifuged to the outside and the majority of this waste is collected by the waste storage container 8.

The small-sized waste (e.g., fine dust) that has not been separated by centrifugation or retained by the separation filter follows the air flow and then flows to the suction motor 16 and the filtering device 23, where the small-sized waste is retained.

The air flow then circulates to the air flow duct 24 and flows along the second surface 27.2 of the sound-absorbing element 27 before escaping past the sound-absorbing element 27 in the direction of the discharge opening 25.

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, in particular from the point of view of the construction of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
