  • the electronic control unit comprises a first electronic board equipped with a first contact that is configured to be activated by the control device when the control device is operated by a user, and a second electronic board equipped with a second contact that is configured to be activated by the activation device when the activation device is operated by a user.
  • the first electronic board can for example be placed in the gripping handle and the second electronic board can for example be placed in the main body.
  • the present invention is intended to remedy all or part of these disadvantages.
  • the technical problem underlying the invention consists in particular of providing a vacuum cleaner which is of simple and economical structure, while having an easier assembly compared to vacuum cleaners of the prior art.
  • the present invention relates to a vacuum cleaner comprising a suction duct; a waste separation device fluidly connected to the suction duct; a main body in which is housed a suction device comprising a motor fan which is configured to generate an air flow through the suction duct and the waste separation device; a gripping handle; a control device which is operable by a user and which comprises a first gripping part; an activation device which is operable by a user and which comprises a second gripping part, the second gripping part being located at a distance from the first gripping part and the first and second gripping parts being movable independently of each other; and an electronic control unit which is configured to control the operation of the motor fan according to a first operating mode when the control device is operated by a user and to control the operation of the motor fan according to a second operating mode when the activation device is operated by a user, the electronic control unit being configured such that a maximum rotation speed of the motor fan in the second operating mode is greater than a maximum rotation speed of the
  • the electronic control unit comprises an electronic board equipped with a first contact and a second contact, the control device being configured to activate the first contact when the control device is operated by a user, and the activation device being configured to activate the second contact when the activation device is operated by a user.
  • the arrangement of the first and second contacts on the same electronic board reduces the manufacturing costs of the electronic control unit, and also simplifies the assembly of the electronic control unit, and therefore, the assembly of the vacuum cleaner. Such a configuration of the first and second contacts therefore makes it possible to significantly reduce the manufacturing costs of the vacuum cleaner.
  • the vacuum cleaner may further have one or more of the following features, taken alone or in combination.
  • the vacuum cleaner is configured such that the maximum power level delivered to the motor fan in the first operating mode is less than the maximum power level delivered to the motor fan in the second operating mode.
  • control device is arranged on the gripping handle.
  • the activation device is arranged next to the control device.
  • Such an arrangement of the activation device allows a user to activate the second operating mode of the motor fan with a single finger, and moreover, to make the activation device more intuitively accessible by the user, since they will not need to look at the vacuum cleaner and/or their hand to reach and operate the activation device.
  • the vacuum cleaner according to the present invention allows a user to easily and quickly, and thus ergonomically and intuitively, activate the second operating mode of the motor fan.
  • control device and the activation device are mounted to be able to rotate respectively about a first axis of rotation and a second axis of rotation.
  • the first and second axes of rotation are substantially parallel.
  • the second axis of rotation of the activation device is placed in front of the first axis of rotation of the control device relative to a median longitudinal axis of the gripping handle.
  • the first axis of rotation of the control device is arranged between the second axis of rotation of the activation device and the median longitudinal axis of the gripping handle.
  • the control device is mounted to be movable in rotation around the first axis of rotation according to a first amplitude of rotation and the activation device is mounted to be movable in rotation around the second axis of rotation according to a second amplitude of rotation, an angular difference between the first and second amplitudes of rotation being less than or equal to 5°, and preferably less than or equal to 2°.
  • the travel paths of the control device and activation device are substantially identical, which improves the user's experience and thus provides an ergonomic advantage.
  • each of the first and second amplitudes of rotation is between 2 and 6°, and is for example about 4°.
  • Such a configuration of the control device and the activation device limits the internal size of the vacuum cleaner, and therefore, the external size of the vacuum cleaner. Indeed, excessively large amplitudes of rotation generate large travel paths of internal devices, requiring more internal space to be provided, resulting in a larger main body.
  • At least one of the control device and the activation device comprises a return arm configured to cooperate with a respective contact among the first and second contacts.
  • the activation device comprises the return arm, the return arm comprising a bearing part that is configured to cooperate with the second contact and a perforated intermediate part that delineates an opening passage, the control device being configured to extend at least partially through the opening passage when the control device is operated by a user.
  • the perforated intermediate part connects the bearing part to the second gripping part.
  • Such a configuration makes it possible to optimize the internal space of the vacuum cleaner at the level of the control and activation devices, while allowing a return arm of the activation device to be symmetrical with respect to a plane of symmetry corresponding to the median longitudinal plane of the vacuum cleaner. This makes it possible to ensure in particular that the forces transmitted from the second gripping part via the return arm to the second contact are symmetrically distributed in the return arm and around the median longitudinal plane of the vacuum cleaner.
  • the activation device preferably the control and activation devices, has/have a symmetrical geometry with respect to a plane of symmetry which, when the vacuum cleaner is mounted, corresponds to the median longitudinal plane of the vacuum cleaner.

  • the first axis of rotation of the control device is arranged between the two lateral branches of the perforated intermediate part.
  • the return arm comprises an elastically deformable portion that is configured to limit the forces applied by the return arm against the respective contact among the first and second contacts.
  • the elastically deformable portion is configured to limit the forces applied by the return arm against the second contact when the activation device is operated by a user.
  • the elastically deformable portion may be formed by a zone of thinner thickness.
  • control device comprises an additional return arm that is configured to cooperate with the first contact.
  • the additional return arm comprises an elastically deformable part that is configured to limit the forces applied by the additional return arm against the first contact when the control device is operated by a user.
  • the elastically deformable part may be formed by a curved zone.
  • At least one, and preferably each, of the first and second contacts is an electromechanical contact, such as a switch, and for example a microswitch.
  • the microswitch may be the “push button” type or the “lever” type.
  • At least one, and preferably each, of the first and second contacts comprises several conductive tracks, and for example two conductive tracks.
  • at least one, and preferably each, of the control device and the activation device comprises an additional contact comprising at least one conductive element such as a pad made of conductive material or an additional conductive track that is configured to cooperate with the conductive tracks provided for on the respective contact.
  • the electronic control unit is configured to control operation of the motor fan according to the second operating mode only as long as the activation device is operated by a user.
  • the electronic control unit is configured to control operation of the motor fan according to the first operating mode as long as the control device is not operated again by a user.
  • the electronic control unit is configured to maintain motor fan operation in the first mode of operation when the control device is released by the user.
  • control device is movable between a resting position and a control position and is configured to be moved into the control position when a first actuating force is applied by a user to the control device
  • activation device is movable between an inactive position and an activated position and is configured to be moved into the activated position when a second actuating force is applied by a user to the activation device.
  • the first and second actuating forces are oriented substantially in the same direction.
  • Such an orientation of the first and second actuating forces provides an ergonomic advantage, since when the control device and the activation device are actuated by a single finger, the finger moves substantially in the same direction whether to actuate the control device or the activation device.
  • control device and the activation device are configured so as to be able to be actuated by the same finger of a user when the user holds the gripping handle.
  • Such a configuration of the control device and the activation device provides an ergonomic advantage allowing the user to quickly switch between the two devices by having to search less for the position of the device to which the finger should go.
  • the finger for example the index finger, will move from a reference position corresponding to the position of the control device to go to the activation device. This reference position does not vary, ensuring the user repeatability of the gesture to actuate the activation device. The same applies for the return of the finger to the control device.
  • control device and the activation device are each configured to be actuated by a user by pulling.
  • Such a configuration of the control device and the activation device provides an ergonomic advantage, since pull actuation is easier than push actuation.
  • control device is configured to be actuated by a user by pulling the control device towards the gripping handle, and/or the activation device is configured to be actuated by a user by pulling the activation device towards the gripping handle.
  • the vacuum cleaner comprises a biasing element configured to bias the control device towards the resting position, and a biasing device configured to bias the activation device towards the inactive position.
  • the biasing element is formed by an elastically deformable tab that is provided on the control device.
  • the elastically deformable tab can be configured to rest against the main body.
  • the elastically deformable tab extends from the first gripping part.
  • the biasing device is formed by a biasing spring.
  • the return arm of the activation device comprises a receiving housing in which the biasing spring is at least partially housed.
  • control device and the activation device are located substantially in a reference plane that is defined by a longitudinal axis of the suction duct and a median longitudinal axis of the gripping handle.
  • the control device and activation device are therefore located in the center of the vacuum cleaner, allowing the user to operate them with one finger, both with the left and right hand.
  • Such an arrangement of the activation device thus allows a user to activate the first and second operating modes of the motor fan, with a single finger, whether right-handed or left-handed.
  • the first and second contacts are vertically offset one above the other when the reference plane is vertical and the longitudinal axis of the suction duct is horizontal.
  • Such an arrangement of the first and second contacts makes it possible to obtain symmetry of the control and activation devices from the first and second gripping parts to the first and second contacts, so that the vacuum can be used by a right-handed or left-handed person, while guaranteeing a transmission of the force exerted on the first and second gripping parts to the first and second contacts which is distributed symmetrically around a median longitudinal plane of the vacuum cleaner, for increased longevity of the activation and control components.
  • the reference plane forms a median longitudinal plane of the vacuum cleaner.
  • control device is located in an upper part of the gripping handle.
  • Such an arrangement of the control device provides an ergonomic advantage, since it allows for actuation of the control device and the activation device with the index finger.
  • the median longitudinal axis of the gripping handle is tilted relative to the longitudinal axis of the suction duct.
  • the first gripping part and the second gripping part are configured to be cut by the same plane that is perpendicular to the median longitudinal axis of the gripping handle.
  • Such a configuration of the first and second gripping parts allows a user, wishing to actuate the activation device, to easily and ergonomically access the activation device, since the latter remains in the anatomical extension zone of the user's finger (index finger), who is able to actuate the control device.
  • control device and the activation device are located close to and under the main body in which the motor fan is housed.
  • the vacuum cleaner comprises a battery housing in which a rechargeable battery is housed, the gripping handle extending between the battery housing and the main body.
  • the electronic board is arranged in the gripping handle.
  • Such an arrangement of the electronic board makes it possible to optimize the internal spaces of the vacuum cleaner, especially when the gripping handle is located between the main body, which houses the suction device, and the battery housing.
  • the activation device is substantially arranged at the intersection of the main body and a support that is connected to the main body and is substantially parallel to the gripping handle.
  • the support extends between the main body and the battery housing, and connects the main body to the battery housing.
  • the activation device comprises a gripping hole.
  • Such a configuration of the activation device facilitates the actuation of the activation device by a user, and thus gives the vacuum cleaner according to the present invention increased ergonomics of use.
  • the gripping hole is oblong. Such a configuration of the gripping hole makes it even easier for a user to manipulate the activation device, since the latter does not have to precisely seek the position of the gripping hole in order to insert their finger therein.

Description

    TECHNICAL FIELD
  • The present invention relates to the field of vacuum cleaners making it possible to suck up dust and waste of small particle size present on a surface to be cleaned, which may for example be tiles, parquet, laminate, carpet or a rug.
  • STATE OF THE ART
  • A vacuum cleaner, and more particularly a portable vacuum cleaner, in known manner comprises a suction duct; a waste separation device fluidly connected to the suction duct; a main body in which is housed a suction device comprising a motor fan which is configured to generate an air flow through the suction duct and the waste separation device; a gripping handle; a control device which is arranged on the gripping handle and which is operable by a user; an activation device which is operable by a user; and an electronic control unit which is configured to control the operation of the motor fan according to a first operating mode, also called normal operating mode, when the control device is operated by a user and to control the operation of the motor fan according to a second operating mode, also called enhanced operating mode, when the activation device is operated by a user.
  • The electronic control unit is more particularly configured such that a maximum rotation speed of the motor fan in the second operating mode is greater than a maximum rotation speed of the motor fan in the first operating mode. Thus, when a user wishes to temporarily give the vacuum cleaner increased suction power, they simply actuate the activation device. Such increased suction power can be useful for sucking up large debris or waste that adheres to the surface to be cleaned.
  • In a known manner, the electronic control unit comprises a first electronic board equipped with a first contact that is configured to be activated by the control device when the control device is operated by a user, and a second electronic board equipped with a second contact that is configured to be activated by the activation device when the activation device is operated by a user. The first electronic board can for example be placed in the gripping handle and the second electronic board can for example be placed in the main body.
  • Such a configuration of the electronic control unit complicates the assembly of the vacuum cleaner, and significantly increases the manufacturing costs of the latter.
  • SUMMARY OF THE INVENTION
  • The present invention is intended to remedy all or part of these disadvantages.
  • The technical problem underlying the invention consists in particular of providing a vacuum cleaner which is of simple and economical structure, while having an easier assembly compared to vacuum cleaners of the prior art.
  • To this end, the present invention relates to a vacuum cleaner comprising a suction duct; a waste separation device fluidly connected to the suction duct; a main body in which is housed a suction device comprising a motor fan which is configured to generate an air flow through the suction duct and the waste separation device; a gripping handle; a control device which is operable by a user and which comprises a first gripping part; an activation device which is operable by a user and which comprises a second gripping part, the second gripping part being located at a distance from the first gripping part and the first and second gripping parts being movable independently of each other; and an electronic control unit which is configured to control the operation of the motor fan according to a first operating mode when the control device is operated by a user and to control the operation of the motor fan according to a second operating mode when the activation device is operated by a user, the electronic control unit being configured such that a maximum rotation speed of the motor fan in the second operating mode is greater than a maximum rotation speed of the motor fan in the first operating mode.
  • The electronic control unit comprises an electronic board equipped with a first contact and a second contact, the control device being configured to activate the first contact when the control device is operated by a user, and the activation device being configured to activate the second contact when the activation device is operated by a user.
  • The arrangement of the first and second contacts on the same electronic board reduces the manufacturing costs of the electronic control unit, and also simplifies the assembly of the electronic control unit, and therefore, the assembly of the vacuum cleaner. Such a configuration of the first and second contacts therefore makes it possible to significantly reduce the manufacturing costs of the vacuum cleaner.
  • The vacuum cleaner may further have one or more of the following features, taken alone or in combination.
  • According to one embodiment of the invention, the vacuum cleaner is configured such that the maximum power level delivered to the motor fan in the first operating mode is less than the maximum power level delivered to the motor fan in the second operating mode.
  • According to one embodiment of the invention, the control device is arranged on the gripping handle.
  • According to one embodiment of the invention, the activation device is arranged next to the control device. Such an arrangement of the activation device allows a user to activate the second operating mode of the motor fan with a single finger, and moreover, to make the activation device more intuitively accessible by the user, since they will not need to look at the vacuum cleaner and/or their hand to reach and operate the activation device. Thus, the vacuum cleaner according to the present invention allows a user to easily and quickly, and thus ergonomically and intuitively, activate the second operating mode of the motor fan.
  • According to one embodiment of the invention, the control device and the activation device are mounted to be able to rotate respectively about a first axis of rotation and a second axis of rotation.
  • According to one embodiment of the invention, the first and second axes of rotation are substantially parallel.
  • According to one embodiment of the invention, the second axis of rotation of the activation device is placed in front of the first axis of rotation of the control device relative to a median longitudinal axis of the gripping handle. In other words, the first axis of rotation of the control device is arranged between the second axis of rotation of the activation device and the median longitudinal axis of the gripping handle. Such an arrangement of the activation device and the control device makes it possible to limit the travel paths of the parts of the activation device and the control device inside the casing of the vacuum cleaner and to ensure increased compactness of the vacuum cleaner according to the present invention.
  • According to one embodiment of the invention, the control device is mounted to be movable in rotation around the first axis of rotation according to a first amplitude of rotation and the activation device is mounted to be movable in rotation around the second axis of rotation according to a second amplitude of rotation, an angular difference between the first and second amplitudes of rotation being less than or equal to 5°, and preferably less than or equal to 2°. Thus, the travel paths of the control device and activation device are substantially identical, which improves the user's experience and thus provides an ergonomic advantage.
  • According to one embodiment of the invention, each of the first and second amplitudes of rotation is between 2 and 6°, and is for example about 4°. Such a configuration of the control device and the activation device limits the internal size of the vacuum cleaner, and therefore, the external size of the vacuum cleaner. Indeed, excessively large amplitudes of rotation generate large travel paths of internal devices, requiring more internal space to be provided, resulting in a larger main body.
  • According to one embodiment of the invention, at least one of the control device and the activation device comprises a return arm configured to cooperate with a respective contact among the first and second contacts.
  • According to one embodiment of the invention, the activation device comprises the return arm, the return arm comprising a bearing part that is configured to cooperate with the second contact and a perforated intermediate part that delineates an opening passage, the control device being configured to extend at least partially through the opening passage when the control device is operated by a user. Advantageously, the perforated intermediate part connects the bearing part to the second gripping part.
  • Such a configuration makes it possible to optimize the internal space of the vacuum cleaner at the level of the control and activation devices, while allowing a return arm of the activation device to be symmetrical with respect to a plane of symmetry corresponding to the median longitudinal plane of the vacuum cleaner. This makes it possible to ensure in particular that the forces transmitted from the second gripping part via the return arm to the second contact are symmetrically distributed in the return arm and around the median longitudinal plane of the vacuum cleaner.
  • According to one embodiment of the invention, the activation device, preferably the control and activation devices, has/have a symmetrical geometry with respect to a plane of symmetry which, when the vacuum cleaner is mounted, corresponds to the median longitudinal plane of the vacuum cleaner.
  • According to one embodiment of the invention, the perforated intermediate part comprises two lateral branches spaced apart from each other and between which the control device is at least partially arranged.
  • According to one embodiment of the invention, the first axis of rotation of the control device is arranged between the two lateral branches of the perforated intermediate part.
  • According to one embodiment of the invention, the return arm comprises an elastically deformable portion that is configured to limit the forces applied by the return arm against the respective contact among the first and second contacts.
  • According to one embodiment of the invention, the elastically deformable portion is configured to limit the forces applied by the return arm against the second contact when the activation device is operated by a user. For example, the elastically deformable portion may be formed by a zone of thinner thickness.
  • According to one embodiment of the invention, the control device comprises an additional return arm that is configured to cooperate with the first contact.
  • According to one embodiment of the invention, the additional return arm comprises an elastically deformable part that is configured to limit the forces applied by the additional return arm against the first contact when the control device is operated by a user. For example, the elastically deformable part may be formed by a curved zone.
  • According to one embodiment of the invention, at least one, and preferably each, of the first and second contacts is an electromechanical contact, such as a switch, and for example a microswitch. For example, the microswitch may be the “push button” type or the “lever” type.
  • According to one embodiment of the invention, at least one, and preferably each, of the first and second contacts comprises several conductive tracks, and for example two conductive tracks. According to such an embodiment of the invention, at least one, and preferably each, of the control device and the activation device comprises an additional contact comprising at least one conductive element such as a pad made of conductive material or an additional conductive track that is configured to cooperate with the conductive tracks provided for on the respective contact.
  • According to one embodiment of the invention, the electronic control unit is configured to control operation of the motor fan according to the second operating mode only as long as the activation device is operated by a user.
  • According to one embodiment of the invention, the electronic control unit is configured to control operation of the motor fan according to the first operating mode as long as the control device is not operated again by a user. Thus, the electronic control unit is configured to maintain motor fan operation in the first mode of operation when the control device is released by the user.
  • According to one embodiment of the invention, the control device is movable between a resting position and a control position and is configured to be moved into the control position when a first actuating force is applied by a user to the control device, and the activation device is movable between an inactive position and an activated position and is configured to be moved into the activated position when a second actuating force is applied by a user to the activation device.
  • According to one embodiment of the invention, the first and second actuating forces are oriented substantially in the same direction. Such an orientation of the first and second actuating forces provides an ergonomic advantage, since when the control device and the activation device are actuated by a single finger, the finger moves substantially in the same direction whether to actuate the control device or the activation device.
  • According to one embodiment of the invention, the control device and the activation device are configured so as to be able to be actuated by the same finger of a user when the user holds the gripping handle. Such a configuration of the control device and the activation device provides an ergonomic advantage allowing the user to quickly switch between the two devices by having to search less for the position of the device to which the finger should go. Indeed, to activate, for example, the activation device, the finger, for example the index finger, will move from a reference position corresponding to the position of the control device to go to the activation device. This reference position does not vary, ensuring the user repeatability of the gesture to actuate the activation device. The same applies for the return of the finger to the control device.
  • According to one embodiment of the invention, the control device and the activation device are each configured to be actuated by a user by pulling. Such a configuration of the control device and the activation device provides an ergonomic advantage, since pull actuation is easier than push actuation.
  • According to one embodiment of the invention, the control device is configured to be actuated by a user by pulling the control device towards the gripping handle, and/or the activation device is configured to be actuated by a user by pulling the activation device towards the gripping handle.
  • According to one embodiment of the invention, the vacuum cleaner comprises a biasing element configured to bias the control device towards the resting position, and a biasing device configured to bias the activation device towards the inactive position.
  • According to one embodiment of the invention, the biasing element is formed by an elastically deformable tab that is provided on the control device. For example, the elastically deformable tab can be configured to rest against the main body.
  • Advantageously, the elastically deformable tab extends from the first gripping part.
  • According to one embodiment of the invention, the biasing device is formed by a biasing spring.
  • According to one embodiment of the invention, the return arm of the activation device comprises a receiving housing in which the biasing spring is at least partially housed.
  • According to one embodiment of the invention, the control device and the activation device are located substantially in a reference plane that is defined by a longitudinal axis of the suction duct and a median longitudinal axis of the gripping handle. The control device and activation device are therefore located in the center of the vacuum cleaner, allowing the user to operate them with one finger, both with the left and right hand. Such an arrangement of the activation device thus allows a user to activate the first and second operating modes of the motor fan, with a single finger, whether right-handed or left-handed.
  • According to one embodiment of the invention, the first and second contacts are vertically offset one above the other when the reference plane is vertical and the longitudinal axis of the suction duct is horizontal. Such an arrangement of the first and second contacts makes it possible to obtain symmetry of the control and activation devices from the first and second gripping parts to the first and second contacts, so that the vacuum can be used by a right-handed or left-handed person, while guaranteeing a transmission of the force exerted on the first and second gripping parts to the first and second contacts which is distributed symmetrically around a median longitudinal plane of the vacuum cleaner, for increased longevity of the activation and control components.
  • According to one embodiment of the invention, the reference plane forms a median longitudinal plane of the vacuum cleaner.
  • According to one embodiment of the invention, the control device is located in an upper part of the gripping handle. Such an arrangement of the control device provides an ergonomic advantage, since it allows for actuation of the control device and the activation device with the index finger.
  • According to one embodiment of the invention, the median longitudinal axis of the gripping handle is tilted relative to the longitudinal axis of the suction duct.
  • According to one embodiment of the invention, the first gripping part and the second gripping part are configured to be cut by the same plane that is perpendicular to the median longitudinal axis of the gripping handle. Such a configuration of the first and second gripping parts allows a user, wishing to actuate the activation device, to easily and ergonomically access the activation device, since the latter remains in the anatomical extension zone of the user's finger (index finger), who is able to actuate the control device. In addition, such a configuration of the first and second gripping parts, combined with a tilt of the gripping handle relative to the longitudinal axis of the suction conduit, provides a very ergonomic arrangement of the gripping zones of the control device, the activation device, and the gripping handle, since the control and activation devices are then naturally accessible. The result is increased user comfort.
  • According to one embodiment of the invention, the control device and the activation device are located close to and under the main body in which the motor fan is housed.
  • According to one embodiment of the invention, the vacuum cleaner comprises a battery housing in which a rechargeable battery is housed, the gripping handle extending between the battery housing and the main body.
  • According to one embodiment of the invention, the electronic board is arranged in the gripping handle. Such an arrangement of the electronic board makes it possible to optimize the internal spaces of the vacuum cleaner, especially when the gripping handle is located between the main body, which houses the suction device, and the battery housing.
  • According to one embodiment of the invention, the activation device is substantially arranged at the intersection of the main body and a support that is connected to the main body and is substantially parallel to the gripping handle.
  • According to one embodiment of the invention, the support extends between the main body and the battery housing, and connects the main body to the battery housing.
  • According to one embodiment of the invention, the activation device comprises a gripping hole. Such a configuration of the activation device facilitates the actuation of the activation device by a user, and thus gives the vacuum cleaner according to the present invention increased ergonomics of use.
  • According to one embodiment of the invention, the gripping hole is oblong. Such a configuration of the gripping hole makes it even easier for a user to manipulate the activation device, since the latter does not have to precisely seek the position of the gripping hole in order to insert their finger therein.
  • According to one embodiment of the invention, the vacuum cleaner comprises a first stop, for example provided on the gripping handle, configured to limit the travel path of the control device to the control position, and a second stop, for example provided on the support connected to the main body, configured to limit the travel path of the activation device to the activation position.
  • According to one embodiment of the invention, the first gripping part and the second gripping part are spaced apart from each other by a distance that is less than 6 cm, and advantageously less than 4 cm, when the control device and the activation device occupy the resting position and the inactive position, respectively. Such a distance makes it possible to switch from the control device to the activation device and vice versa, without having to release the gripping handle and without having to stretch the finger to an uncomfortable position when moving from one control to another.
  • According to one embodiment of the invention, the control device is a control trigger or a control button.
  • According to one embodiment of the invention, the activation device is an activation trigger or an activation button.
  • According to one embodiment of the invention, the waste separation device extends along a first extension axis and the motor fan extends along a second extension axis that is substantially parallel to the first extension axis.
  • According to one embodiment of the invention, the waste separation device is cyclonic.
  • According to one embodiment of the invention, the suction device comprises a motor casing in which the motor fan is placed.

  • DETAILED DESCRIPTION
  • FIGS. 1 to 7 show a vacuum cleaner 2 that is portable and includes a main body 3, a gripping handle 4 connected to the main body 3, a waste separation device 5 removably mounted on the main body 3, and a suction device 6 housed in the main body 3.
  • The waste separation device 5 is advantageously cyclonic, and comprises in particular a waste storage container 7, and a separator filter (not visible in the figures) housed in the waste storage container 7. The waste storage container 7 has, in particular, an air inlet opening and an air outlet opening.
  • As shown in FIG. 7 , the suction device 6 comprises a motor casing 12 and a motor fan 13 arranged in the motor casing 12. In a known manner, the motor fan 13 comprises a fan 13.1 and an electric motor 13.2 configured to rotate the fan.
  • The suction device 6 further comprises an air inlet port 14 and one or more air discharge ports 15 that are advantageously provided on the motor casing 12. The air inlet port 14 of the suction device 6 can be connected to the air outlet opening of the waste separation device 5 directly or via a connecting pipe.
  • According to the embodiment shown in the figures, the waste separation device 5 extends along a first extension axis A, and the motor fan 13 extends along a second extension axis B that is substantially parallel to the first extension axis A, and which can be confused with the first extension axis A.
  • The vacuum cleaner 2 further comprises a rechargeable battery 16 configured to electrically power the motor fan 13. The rechargeable battery 16 is advantageously housed in a battery housing 17 connected to the gripping handle 4, and more specifically to a lower part of the gripping handle 4. Advantageously, the vacuum cleaner 2 comprises a support 18 that extends substantially parallel to the gripping handle 4 and that connects the battery housing 17 to the main body 3.
  • The vacuum cleaner 2 further comprises a suction duct 19 to which the air inlet opening of the waste separation device 5 is fluidly connected. Advantageously, the suction duct 19 extends substantially parallel to the first and second extension axes A, B. The motor fan 13 is more specifically configured to generate an air flow through the suction duct 19 and the waste separation device 5.
  • The vacuum cleaner 2 also comprises a band coupler 21 fluidly connected to the suction duct 19 and to which a suction tube nozzle can be connected, which can itself be connected to a suction head provided with a sole intended to be oriented towards a floor to be cleaned.
  • The vacuum cleaner 2 further comprises an electronic control unit 22 which is configured to control the operation of the motor fan 13 according to a first operating mode, also known as normal operating mode, wherein the motor fan 13 is driven in rotation at a first rotation speed, and to control the operation of the motor fan 13 according to a second operating mode, also known as enhanced operating mode, wherein the motor fan 13 is driven in rotation at a second rotation speed that is greater than the first rotation speed. Thus, according to the second operating mode, the negative pressure generated in the suction duct 19 is greater than the negative pressure generated in the latter when the motor fan 13 operates according to the first operating mode.
  • In order to be able to control the operation of the motor fan 13 according to the two aforementioned operating modes, the vacuum cleaner 2 comprises a control device 23 which is arranged advantageously on an upper part of the gripping handle 4 and which can be operated by a user, and an activation device 24 which is arranged opposite the control device 23 and which can also be operated by a user. The control device 23 may be, for example, a control trigger or a control button, and the activation control 24 may be, for example, an activation trigger or an activation button.
  • The control device 23 is movable between a resting position and a control position and is configured to be moved into the control position when a first actuating force is applied by a user to the control device 23, and the activation device 24 is movable between an inactive position and an activated position and is configured to be moved into the activated position when a second actuating force is applied by a user to the activation device 24.
  • The electronic control unit 22 is more specifically configured to control the operation of the motor fan 13 according to the first operating mode when the control device 23 is actuated by a user, i.e. is moved to the control position, and to control the operation of the motor fan 13 according to the second operating mode when the activation device 24 is actuated by a user, i.e. is moved to the activation position.
  • According to the embodiment represented in the figures, the control device 23 and the activation device 24 are configured so as to be able to be actuated by the same finger of a user when the user holds the gripping handle 4. Advantageously, the control device 23 is configured to be actuated by a user by pulling the control device 23 towards the gripping handle 4, and the activation device 24 is configured to be actuated by a user by pulling the activation device 24 towards the gripping handle 4. Thus, the first and second actuating forces to be applied respectively to the control device 23 and the activation device 24 to actuate them are oriented substantially in the same direction.
  • According to the embodiment represented in the figures, the control device 23 and the activation device 24 are located substantially in a reference plane that is defined by a longitudinal axis C of the suction duct 19 and a median longitudinal axis D of the gripping handle 4, and which forms, for example, a median longitudinal plane of the vacuum cleaner 2. Advantageously, the control device 23 and the activation device 24 are located close to and under the main body 3 in which the motor fan 13 is housed.
  • According to the embodiment shown in the figures, the activation device 24 is arranged substantially at the intersection of the main body 3 and the support 18 that connects the battery housing 17 to the main body 3.
  • As shown in FIGS. 6 , the control device 23 is mounted to be movable in rotation around a first axis of rotation R1 according to a first amplitude of rotation and the activation device 24 is mounted to be movable in rotation around a second axis of rotation R2 according to a second amplitude of rotation. The first and second axes of rotation R1, R2 are parallel, and the second axis of rotation of the activation device 24 is placed in front of the first axis of rotation R1 of the control device 23 with respect to the median longitudinal axis D of the gripping handle 4. According to one embodiment of the invention, each of the first and second rotation amplitudes is between 2 and 6°, and is for example about 4°, and an angular difference between the first and second rotation amplitudes is less than or equal to 5°, and preferably less than or equal to 2°.
  • According to the embodiment shown in the figures, the electronic control unit 22 comprises an electronic board 25 which is arranged in the gripping handle 4 and which is equipped with a first contact 26 and a second contact 27. For example, first and second contacts 26, 27 are vertically offset one above the other when the reference plane is vertical and the longitudinal axis C of the suction duct 19 is horizontal. The control device 23 is configured to activate the first contact 26 when the control device 23 is actuated by a user, i.e. is moved to the control position, and the activation device 24 is configured to activate the second contact 27 when the activation device 24 is actuated by a user, i.e. is moved to the activation position. Each of the first and second contacts 26, 27 may be an electromechanical contact, such as a switch, and for example a microswitch.
  • The electronic control unit 22 is configured to transmit to the motor fan 13 a control signal, which is configured to control the operation of the motor fan 13 in the first operating mode, when the first contact 26 is activated, and to transmit to the motor fan 13 an activation signal, which is configured to control operation of the motor fan 13 in the second operating mode, when the second contact 27 is activated. Advantageously, the electronic control unit 22 is configured to control operation of the motor fan 13 according to the second operating mode only as long as the activation device 24 is actuated by a user, i.e. only as long as the second contact 27 is kept activated by the activation device 24, and is configured to control operation of the motor fan 13 according to the first operating mode until the control device 23 is actuated again by a user, i.e. until the first contact 26 is activated again by the activation device 24. Thus, the electronic control unit 22 is configured to maintain motor fan 13 operation in the first mode of operation when the control device 23 is released by the user.
  • As shown in FIG. 4 , the control device 23 comprises a first gripping part 28 and the activation device 24 comprises a second gripping part 29 which is located at a distance from the first gripping part 28 and which is movable independently of the first gripping part 28.
