Multi-functional vacuum cleaner

Abstract

Disclosed herein is a multi-functional vacuum cleaner, which can be used as a combined vacuum cleaner of a canister type vacuum cleaner which is easy to move and convenient to use when cleaning narrow areas, and of an upright type vacuum cleaner when is easy to use when cleaning wide areas. The vacuum cleaner comprises a body comprising a dust collection unit and a driving unit, a handle part separably connected with the body, and a brush detachably attached to the body to suck foreign matter. The brush supports the body when being attached to the body. The handle part and / or the brush can be independently and detachably attached to the body. Thus, the vacuum cleaner can be freely moved, and used for cleaning narrow areas as well as wide areas.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a multi-functional vacuum cleaner, and more particularly to a multi-functional vacuum cleaner, which can be used as a combined vacuum cleaner of a canister type vacuum cleaner and an upright type vacuum cleaner. [0003] 2. Description of the Related Art [0004] Generally, a vacuum cleaner is an apparatus which cleans a room in such a way of removing foreign matter such as dust on a floor by sucking the foreign matter along with air into a body of the vacuum cleaner by generating suction force using a motor positioned in the body, and then collecting the foreign matter in a dust collection unit while allowing the air having the foreign matter removed therefrom to be discharged to an outside of the body. The vacuum cleaner is generally classified into a canister type, an upright type, a drum type, a handy type, and the like. [0005] The canister type vacuum cleaner comprises a body, a dus...

AI Technical Summary

Benefits of technology

[0011] It is another object of the present invention to provide the multi-functional vacuum cleaner, which allows a handle part and a brush to be separated from a body, thereby enabling convenient use of the vacuum cleaner depending on utility of the vacuum cleaner.

[0012] It is yet another object of the present invention to provide the multi-functional vacuum cleaner, which allows a hose connecting a first connection part formed on an upper portion of the body with a third connection part extending from one side of a lower portion of the brush to be separated from the third connection part, and to be connected with the handle part, a distal end of which is connected with one of various suction devices, thereby ensuring free movement of the vacuum cleaner while enabling cleaning of a narrow area.

[0014] In accordance with another aspect of the present invention, a multi-functional vacuum cleaner comprises: a body comprising a dust collection unit, a driving unit, a first connection part connected with one end of a hose, and a second connection part to which a handle part can be inserted, the first and second connection parts being formed on an upper portion of the body; the handle part separably connected with the second connection part of the body, and comprising a handle to be gripped by a user and a fourth connection part connectable with the other end of the hose; and a brush comprising a third connection part connected with the other end of the hose, the one end of which is connected with the body, and wheels mounted to lower opposite sides of the brush to enable easy movement of the vacuum cleaner.

Problems solved by technology

However, the canister type vacuum cleaner has problems in that, it is very difficult to move the body, the extension pipe and suction device connected by the connection pipe at the same time, cleaning efficiency is reduced in a large area, and in that it is inconvenient to maintain the canister type vacuum cleaner due to the long extension pipe.

However, the upright type vacuum cleaner is inconvenient to use for cleaning narrow areas or corners, and fails to remove dust therefrom due to a space occupied by the brush supporting the body.

Furthermore, the upright type vacuum cleaner has a problem in that it is difficult to change a direction of the brush since the body and the brush are heavy, causing difficulty in adjustment of the handle.
