Description

The present invention relates to the field of vacuum cleaners for sucking dirt and dust of small particle size from surfaces to be cleaned, which may be, for example, tiles, parquet, laminates, carpets or rugs. .

A vacuum cleaner, more particularly a hand-held vacuum cleaner, in a known manner produces a suction duct, a dust separating device fluidly connected to the suction duct, and an air flow through the suction duct and the dust separating device. a body containing a suction device including a motor fan configured to: a gripping handle; a control member disposed on the gripping handle and operable by a user, the control member comprising: a control member configured to control operation of the motor fan in a normal operating mode when operated by a user; and a user-operable actuation member, wherein the actuation member is operated by the user. an actuating member configured to control operation of the motor fan in the augmented mode of operation.

In particular, the vacuum cleaner is configured such that the maximum rotational speed of the motor fan in the boosted mode of operation is higher than the maximum rotational speed of the motor fan in the normal mode of operation. Therefore, when the user wishes to temporarily give the vacuum cleaner increased suction power, the user actuates the actuating member. Such increased suction power is particularly useful for sucking large dust particles or dust particles adhering to the surface to be cleaned.

In a known manner the actuating member is arranged at the rear of the body of the vacuum cleaner. Such placement of the actuating member requires the use of the user's second hand to operate the actuating member, which some users find particularly useful for supporting the front portion of the body. , can be uncomfortable for the user using their second hand.

The present invention is intended to remedy all or part of these shortcomings.
The technical problem underlying the present invention is, inter alia, to provide a vacuum cleaner which is simple and economical in construction and at the same time more ergonomic to use.

Such placement of the actuating member allows the user to activate the second operating mode of the motor fan with one finger, and the user can reach and operate the actuating member. Since it is not necessary to look at the vacuum cleaner and/or the user's hand to do so, it allows the actuating member to be more intuitively accessible by the user. The vacuum cleaner according to the invention thus allows the user to easily and quickly, and therefore ergonomically and intuitively, activate the second operating mode of the motor fan.
