Vacuum cleaner.

Abstract

A vacuum cleaner is disclosed. The vacuum cleaner includes a suction motor to draw in dirt or dust into a cleaner body through a suction nozzle, a dust collecting unit to collect the dirt or dust drawn into the cleaner body and having a discharging hole to discharge air, and a filter assembly) detachably joined to the cleaner body on an air discharging passage between the dust collecting unit and the suction motor, and provided as a member separate from the dust collecting unit.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2006-0132482 filed in the Korean Intellectual Property Office on December 22, 2006, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a cleaner, and more particularly, to a vacuum cleaner that uses suction to draw dirt or dust from a surface to be cleaned and thereby performs a cleaning operation. Background technique [0004] Generally, a vacuum cleaner generates suction by using a suction motor disposed in a cleaner body, and draws dust or dirt along with air from a surface to be cleaned using the suction. The drawn-in air laden with dust or dirt is freed of dust or dirt while passing through the dust collecting unit, so that only the purified air is discharged out of the cleaner body. [0005] However, a conventional vacuum cleaner is configured such that, as d...

Problems solved by technology

When the filter is set in a state where it is not separated from the dust collection unit as described above, there may be a problem with conventional vacuum cleaners that if large dust or dirt flows into the dust collection unit, the filter will be damaged due to the large Dust or dirt is clogged, causing a large load on the suction motor, thus reducing the life of the suction motor and reducing the efficiency of the filter for fine dust

Therefore, there arises a problem that the use of the conventional vacuum cleaner is inconvenient since the dust or dirt collected in the dust collecting unit should be frequently dumped, that is, the maintenance cycle is shortened.

In addition, according to the conventional vacuum cleaner, the dust collecting unit collects the fine dust along with the large dust or dirt due to the structure, so that the fine dust and the large dust or dirt are dumped together

[0006] In addition, conventional vacuum cleaners are inconvenient in that as long as the user does not directly draw the filter to the outside, she or he cannot accurately grasp the contamination level of the filter
