Description

Vacuum cleaner

Technical Field

The present invention relates to the field of vacuum cleaners allowing to suck in 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 vacuum cleaner, more particularly a portable vacuum cleaner, comprises, in a known manner: a suction duct; a waste separation device fluidly connected to the suction conduit; a main housing in which an inhalation device is housed, the inhalation device comprising an electrically powered ventilator configured to generate an air flow through an inhalation conduit and a waste separation device; and a grip handle comprising a central longitudinal axis that is inclined relative to the longitudinal axis of the inhalation conduit.

The main housing of such a cleaner is formed from a large number of separate components, which complicates assembly of the cleaner and significantly increases the manufacturing costs of the cleaner. In addition, such a portable cleaner should be as light in weight and small in size as possible for the sake of comfort in use. In addition, portable cleaners having good structural strength to withstand a starting torque of, for example, an electric ventilator set of the portable cleaner have also been studied. These standards are contradictory, in that the structural strength of a portable cleaner is usually and partly ensured by its housing, the shape and complexity of which tends to weigh the cleaner and increase its overall size. This compromise between light weight and small size on the one hand and structural strength on the other is often difficult to achieve.

SUMMERY OF THE UTILITY MODEL

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

The technical problem on which the present invention is based consists in particular in providing a vacuum cleaner which is simple in construction, light in weight, of limited dimensions and economical, while remaining reliable.

To this end, the utility model relates to a vacuum cleaner comprising: a suction duct; a waste separation device fluidly connected to the suction conduit; a main housing in which is housed suction means comprising an electrically powered ventilator extending along a motor axis and configured to generate an air flow through the suction conduit and the waste separation device; and a grip handle

The main case includes:

-a first casing portion comprising a first branch in which the suction duct is housed, a second branch forming a front portion of the grip handle, and a third branch at least partially defining a housing chamber in which the suction device is housed; and

-a second casing portion provided in the rear of the vacuum cleaner, the second casing portion comprising a primary branch forming the rear of the grip handle and a secondary branch at least partially defining the housing chamber in which the suction device is housed.

Thus, according to the utility model, the grip handle is formed by the second branch of the first shell portion and the primary branch of the second shell portion.

This configuration of the main housing according to the utility model makes it possible, on the one hand, to optimize the geometry of the main housing in accordance with the dimensions of the electric ventilator and, on the other hand, to simplify the molding of the main housing and, in particular, the demolding of the first housing part. In addition, this configuration of the main housing allows to limit the number of components required to form the main housing. The configuration of the main casing according to the utility model therefore allows to significantly reduce the manufacturing costs of the cleaner, to limit the dimensions of the casing, in particular at the rear of the cleaner, and to reduce the weight of the rear of the cleaner.

In addition, the particular configuration of the second casing portion allows to rigidify the second and third branches of the first casing portion and thus to impart good structural strength to the main casing and thus to the vacuum cleaner according to the utility model, while limiting the overall mass of the vacuum cleaner.

Furthermore, the configuration of the second branch of the first shell portion and of the primary branch of the second shell portion facilitates the installation of an electronic control unit, and in particular of an electronic card of the electronic control unit, in the grip handle when necessary, and ensures easy access to the electronic control unit within the scope of maintenance of 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 mounting of the electric ventilator in the first housing portion.

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

According to one embodiment of the utility model, the second shell portion has a generally square shape. This particular configuration of the second housing portion helps to improve the structural strength of the housing of the vacuum cleaner.

This configuration of the primary and secondary branches allows a gap to be formed at the rear of the cleaner, in particular below the main housing portion housing the electric ventilator, and thus avoids the user's forearms coming into contact with the rear of the cleaner when it is in use. In addition, this shape of the second housing portion facilitates gripping of the grip handle when the cleaner is disposed on its base. This configuration of the primary and secondary branches thus gives the cleaner increased ergonomic use.

The grip handle is inclined at an inclination angle of between 110 ° and 140 °, preferably between 120 ° and 130 °, with respect to the longitudinal axis of the suction duct, allowing the cleaner to be held in a more natural and ergonomic position of the hand and wrist.

The rear of the cleaner is raised rearwardly when the first and second branches of the first housing portion are inclined 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 °. These arrangements also facilitate gripping of the grip handle, particularly when the cleaner is arranged on its base in an upright position with its attachment sleeve down, and thus give the cleaner an increased ergonomic use.
