Vacuum Cleaner

Abstract

The present invention relates to a vacuum cleaner, and more particularly, to a bagless vacuum cleaner. The vacuum cleaner (1) comprises a dust separating device (5), provided with a dust outlet (29), for separating dust from an incoming air flow, and a dust collecting container (7) being arranged at the dust separating device for receiving dust via the dust outlet from the dust separating device. The dust separating device comprises a first part (5a) and a second part (5b) being releasably connectable to each other, wherein the second part (5b) of the dust separating device is arranged to be movable in the dust collecting container (7) after being released from the first part (5a) of the dust separating device for compressing dust received in the dust collecting container.

Description

TECHNICAL FIELD[0001]The present invention relates to a vacuum cleaner, and more particularly, to a bagless vacuum cleaner. The invention is intended for use particularly but not exclusively in a bagless vacuum cleaner comprising one or more dust separating steps wherein the dust separation takes place in one or more cyclone separation units.BACKGROUND OF THE INVENTION[0002]Generally, a vacuum cleaner includes a suction nozzle for sucking air and dust while the suction nozzle moves along a surface, a main body with a motor and a fan for generating air suctioning force through the suction nozzle and a dust collecting unit.[0003]Particularly in bagless type vacuum cleaners gravity is used to drop dust and other foreign particles in the dust collecting unit. The space in the dust collecting unit is rather limited and is easily filled up by loosely compacted dust. The dust collecting unit should therefore be emptied frequently which may cause inconvenience to the user. However, if the d...

AI Technical Summary

Benefits of technology

[0019]The handle bar of the actuator is designed to be actuated by a user of the vacuum cleaner. Unlocking of the actuator and compression of dust in the dust collecting container may be done during operation of the vacuum cleaner. This is an advantage as the dust compression operation is booth easy and quickly performed. After the dust has been compressed in the dust collecting container, the actuator is brought back to the locked position and the user may continue the cleaning business.

[0020]In an embodiment, the dust collecting container together with the second part of the dust separating device is removable from the vacuum cleaner. Preferably, the compression of dust can also be made

Problems solved by technology

The space in the dust collecting unit is rather limited and is easily filled up by loosely compacted dust.

The dust collecting unit should therefore be emptied frequently which may cause inconvenience to the user.

However, if the dust container is not emptied often enough, the build up of dust in the dust collecting unit will disturb the air flow and cause lowered dust separation efficiency.

A drawback with the system described i
