Description

TECHNICAL FIELD

The present invention relates to the field of vacuum cleaners for vacuuming dust and small particle size waste present on a surface to be cleaned, which may for example be tile, parquet, laminate, carpet or a rug.

STATE OF THE ART

A vacuum cleaner, and more particularly a handheld vacuum cleaner, comprises a suction pipe in a known manner; a waste separation device fluidly connected to the suction pipe; a main housing in which a suction device, comprising a motor fan, is housed which is configured to generate an air flow through the suction pipe and the waste separation device; and a gripping handle comprising a median longitudinal axis which is tilted relative to a longitudinal axis of the suction pipe.
The main housing of said vacuum cleaner is made up of a large number of separate parts, which makes assembling the vacuum cleaner more complex and significantly increases the manufacturing costs of the vacuum cleaner. In addition, for ease of use, this type of handheld vacuum cleaner should be as light as possible, with a very small size. Furthermore, handheld vacuum cleaners with good structural strength must also be able to withstand, for example, the starting torque of the motor-fan unit of the handheld vacuum cleaner. These criteria are antagonistic since the structural strength of a handheld vacuum cleaner is generally and partly provided by its housing, the shape and complexity of which tend to make it heavier and increase the overall size of the vacuum cleaner. This trade-off between on the one hand, a light weight and small size, and structural strength on the other hand, is usually difficult to achieve.

SUMMARY OF THE INVENTION

The present invention is intended to remedy all or part of these disadvantages.
The technical problem at the base of the invention is to provide a vacuum cleaner that is simple in structure, lightweight, with a limited size and economical, while remaining reliable.
To this end, the present invention concerns a vacuum cleaner comprising a suction pipe; a waste separation device fluidly connected to the suction pipe; a main housing in which a suction device comprising a motor fan is housed, which extends along an axis of the motor and which is configured to generate an air flow through the suction pipe and the waste separation device; and a gripping handle.
The main housing includes:

- a first housing portion comprising a first branch in which the suction pipe is housed, a second branch forming a front portion of the gripping handle and a third branch at least partially defining a receiving chamber in which the suction device is housed, and
- a second housing portion placed in a rear portion of the vacuum cleaner, the second housing portion comprising a primary branch forming a rear portion of the gripping handle, and a secondary branch at least partially defining the receiving chamber in which the suction device is housed.

According to the present invention, the gripping handle is therefore formed by the second branch of the first housing portion and by the primary branch of the second housing portion.
Such a configuration of the main housing according to the invention makes it possible, on the one hand, to optimize the geometry of the main housing according to the volume of the motor fan, and on the other hand, to simplify the molding of the main housing, and in particular the demolding of the first housing portion. In addition, such a configuration of the main housing will limit the number of parts needed to form the main housing. The configuration of the main housing according to the present invention thus makes it possible to significantly reduce the manufacturing costs of the vacuum cleaner, to limit the volume of the housing, in particular at the rear part of the vacuum cleaner, and to lighten the rear part of the vacuum cleaner.
In addition, the specific configuration of the second housing portion makes it possible to rigidify the second and third branches of the first housing portion, and thus provides good structural strength to the main housing, and therefore to the vacuum cleaner according to the present invention, while limiting the overall mass of the vacuum cleaner.
Moreover, the configuration of the second branch of the first housing portion and of the primary branch of the second housing portion facilitates the possible mounting of an electronic control unit, and in particular of an electronic board of said electronic control unit in the gripping handle, and ensures easy access to the electronic control unit, for example to repair the vacuum cleaner. The configuration of the second branch of the first housing portion and the primary branch of the second housing portion also facilitates the mounting of the motor fan in the first housing portion.
The vacuum cleaner may further have one or more of the following features, alone or in combination.
According to one embodiment of the invention, the second housing portion has an overall square shape. This particular configuration of the second housing portion contributes to the improvement of the structural strength of the vacuum housing.
According to one embodiment of the invention, the primary branch of the second housing portion is attached, for example by screwing, to the second branch of the first housing portion, to form the gripping handle.
According to one embodiment of the invention, the secondary branch of the second housing portion is attached, for example, by screwing to the third branch of the first housing portion.
According to one embodiment of the invention, the gripping handle comprises a median longitudinal axis that is tilted relative to a longitudinal axis of the suction pipe.
According to one embodiment of the invention, the first, second and third branches of the first housing portion form a Y-shape.
According to one embodiment of the invention, the primary and secondary branches of the second housing portion form a V-shape. Such a configuration of the primary and secondary branches makes it possible to form a clearance at the rear of the vacuum cleaner, and in particular under the part of the main housing that houses the motor fan, and thus to avoid contact of a user's forearm with the rear part of the vacuum cleaner when using the vacuum cleaner. In addition, such a shape of the second housing portion facilitates gripping the gripping handle when the vacuum cleaner is placed on its base. Thus, such a configuration of the primary and secondary branches increases the ergonomics of the vacuum cleaner.
According to one embodiment of the invention, the primary and secondary branches of the second housing portion are complementary to the second and third branches of the first housing portion, respectively.
According to one embodiment of the invention, the second and third branches of the first housing portion form a V-shape. Advantageously, the V-shape of the second housing portion is placed between the second and third branches of the first housing portion, and the V-shape of the second housing portion is complementary to the V-shape formed by the second and third branches of the first housing portion. This configuration helps improve the structural strength of the vacuum cleaner.
According to one embodiment of the invention, the second and third branches of the first housing portion are tilted relative to each other at an angle of inclination of between 80 and 100°. Advantageously, the primary and secondary branches of the second housing portion are tilted relative to each other at the same angle, i.e. at an angle of inclination of between 80 and 100°. Such a configuration of the first housing portion facilitates the demolding of the first housing portion.
Advantageously, the first and second branches of the first housing portion are tilted relative to each other at an angle of inclination of between 110 and 140°, preferably between 120° and 130°. This provision makes it possible to tilt the gripping handle in relation to the longitudinal axis of the suction pipe at the same angle of inclination. The inclination of the gripping handle with respect to the longitudinal axis of the suction pipe at an angle of inclination of between 110 and 140°, preferably between 120° and 130°, makes it possible to hold the vacuum cleaner using a more natural and ergonomic hand and wrist position.
When the first and second branches of the first housing portion are tilted relative to each other at an angle of inclination of between 110 and 140° and the angle of inclination between the second and third branches of the first housing portion and the angle of inclination between the primary and secondary branches of the second housing portion are each between 80 and 100°, the rear of the vacuum cleaner is raised towards the rear. These provisions also facilitate the gripping of the gripping handle, particularly when the vacuum cleaner is placed on its base in an upright position with its coupling sleeve facing down, thus increasing the ergonomics of use of the vacuum cleaner.
According to one embodiment of the invention, the first housing portion is made in one single piece. These provisions further reduce the manufacturing costs of the main housing and simplify assembly of the main housing, thus reducing the manufacturing costs of the vacuum cleaner.
According to one embodiment of the invention, the second housing portion is made in one single piece These provisions further reduce the manufacturing costs of the main housing and simplify assembly of the main housing, thus reducing the manufacturing costs of the vacuum cleaner.

According to one embodiment of the invention, the third branch of the first housing portion forms a loop with an opening in its center, opening in a direction that is substantially parallel to the median longitudinal axis of the gripping handle. This particular structure makes it possible to facilitate manufacturing by molding of the first part of the housing and improving the ease of assembly and disassembly of the vacuum cleaner, in particular the ease of assembly of the motor fan unit in the vacuum cleaner housing.
According to one embodiment of the invention, the vacuum cleaner comprises a battery housing in which a rechargeable battery is accommodated, the battery housing being attached to a lower end of the gripping handle.
According to one embodiment of the invention, the battery housing is attached to one end of the second branch of the first housing portion that is opposite to the third branch.
According to one embodiment of the invention, the first housing portion comprises a pillar that is substantially parallel to the gripping handle and extends between the first branch of the first housing portion and the battery housing.
According to one embodiment of the invention, the secondary branch of the second housing portion has a lower surface that is raised towards the rear of the main housing so that the lower surface extends towards the rear in the direction of the motor axis of the motor fan. These provisions further facilitate the gripping of the gripping handle, especially when the vacuum cleaner is placed on its base.
