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) which is provided with a dust outlet (29) and used 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 particularly but not exclusively intended for use in a bagless vacuum cleaner comprising one or more dust separation steps, wherein the dust separation takes place in one or more cyclone separation units. Background technique [0002] Typically, a vacuum cleaner includes: a nozzle that sucks in air and dust as it moves along a surface; a body with an electric motor and a fan for creating air suction through the nozzle; and a Dust collection unit. [0003] Especially in bagless vacuum cleaners, gravity is used to cause dust and other foreign particles to fall into the dust collection unit. The space in such dust collection units is rather limited and easily filled with loosely packed dust. Therefore, the dust collection unit should be emptied frequently, which causes inconvenience to users. However, if the dust collection container...
