Embodiment Construction

[0039] [39] If Figure 1-3 As shown, the vacuum cleaner 1 consists of a vacuum cleaner body consisting of a lower body 2, an upper body 4 and a cover 6 which closes the slot 8 of the vacuum cleaner bag. The rear surface of the slot 8 includes openings in air communication with the motor chamber.

[0040] [40] The cover 6 is also provided with a connection 10 for connecting the suction pipe to the storage bag for the air filter and suction waste. The circular portion of the front of the upper body forms the handle 11 .

[0041] [41] The upper body 4 is also provided with mechanisms 12, 14 and 16 for respectively controlling the start and stop of the motor, the winding of the electric wire and the power of the motor. Bleeding of air from the motor is achieved through an assembly 18 located on the upper body 4 at the rear of the device.

[0042] [42] The vacuum cleaner motor 20 is located in a fairing 22 connected to the air outlet opening of the collection bag tank 8 .

Abstract

The invention relates to a vacuum cleaner (1) comprising a frame in which an electric motor (20) is housed, the electric motor (20) being connected to a fan, in operation, upstream of said electric motor (20) , starting from a duct - which ends in a suction nozzle, until the air outlet of the frame located downstream of the electric motor (20), an intake of air can be generated, a filter device is located on the pneumatic path, and Preferably located upstream of the motor (20), an adjustment device (200, 400) for adjusting the air flow in the vacuum cleaner (1) is located on the pneumatic path upstream of the motor (20), when the motor (20) In operation, said regulating means (200, 400) causes a change in the air flow area passing through it in the event of a change in the flow rate, characterized in that it is in the range of 80% to 100% of a predetermined maximum flow rate A change in the air flow area is achieved.

Description

technical field [0001] [01] The present invention relates to the field of vacuum cleaner household appliances, in particular to the structure of the vacuum cleaner. [0002] [02] The purpose of this invention is to propose a device that can automatically adjust the flow rate of the vacuum cleaner. [0003] [03] More particularly, the purpose of the present invention is to limit the maximum flow rate of the vacuum cleaner in order to limit the noise of the vacuum cleaner and at the same time reduce the clogging speed of the filter, which will guarantee a large effective power. [0004] [04] The object of the invention is also to limit flow fluctuations in the pneumatic suction chain, which may be related, for example, to clogging of the collection bag. Background technique [0005] [05] In fact, when the waste collection bag is blocked, it is difficult for the air to pass through said bag, thus reducing the air flow, and increasing the negative pressure, thus reducing the ov...
