Description

Dust removing unit in vacuum cleaner

The present invention relates to a vacuum cleaner. More specifically, by improving the structure of the dust collecting unit which performs the dust collection by centrifugal separation method, it can be effectively installed even in a narrower space, and the dust collecting unit of the vacuum cleaner which can quickly and conveniently dispose the collected dirt to the outside. It is about.

The vacuum cleaner is a device that collects the collected dirt by filtering the dirt inside the main body after suctioning the air containing the foreign matter by using the vacuum pressure formed by the vacuum motor installed inside the main body.

As a filter for filtering foreign substances to be sucked, a paper filter having a regular envelope shape has been generally used. Such a paper filter filters out foreign matters such as dust contained in the sucked air by allowing air to pass but leaving foreign matters such as dust inside.

However, when a vacuum cleaner having such a paper filter accumulates a certain level of foreign matter inside the paper filter by using it for a long time, the suction force of the vacuum cleaner is lowered, and the inconvenience of using the paper filter periodically has to be replaced. There was a ham.

In order to alleviate this inconvenience, a vacuum cleaner for performing cyclone filtering has been proposed.

1 is a view illustrating a vacuum cleaner that performs a general cyclone filtering method.

Referring to FIG. 1, a vacuum cleaner includes a main body 1 having a suction means for sucking air in a room, a connection hose 5 made of a flexible material connected to communicate with an inside of the main body 1, and the connection hose.
