Disclosed is an upright type vacuum cleaner having a dust compression device which automatically compresses dust in a dust collection device during cleaning. The upright type vacuum cleaner includes a main body, a dust collection device provided in the main body and collecting dust, the dust compression device provided within the dust collection device, the size of the dust compression device being selectively changeable according to pressure change therein to compress dust within the dust collection device, a vacuum suction motor provided on the main body and forming vacuum suction pressure, and a flow passage switch device communicating the dust compression device selectively with the vacuum suction motor or the external atmosphere. The dust compression device selectively communicates with the vacuum suction motor or the external atmosphere, and may thus repeatedly compress dust in the dust collection device.

Upright type vacuum cleaner having dust compression device

A vacuum cleaner is disclosed. The vacuum cleaner includes a dust separation device provided in a body; a dust collection device connected with the dust separation device; a dust compression part movably provided in the dust collection device, to compress dust by applying a pressure to dust collected in the dust collection device selectively; a liquid accommodation part provided in the dust collection device or the body, to accommodate a predetermined liquid; and a liquid exhaustion part connected with the liquid accommodation part, to exhaust the liquid toward the dust in the dust compression performed by the dust compression part, wherein the liquid exhaustion part comprises an opening/closing member provided therein to control flow of the liquid, and the opening/closing member is transformed by an external force to guide the liquid to be exhausted outside the liquid exhaustion part.

Vacuum cleaner

A vacuum cleaner is disclosed. The vacuum cleaner includes a body having a vacuum motor provided therein; a dust collection device provided in the body to collect dust; a dust compression device expandable or contractible selectively; a passage switching device configured to selectively communicate the dust compression device with a low pressure part having a lower pressure than a pressure of the dust collection device and a high pressure part having a higher pressure than a pressure of the dust collection device.
