Description

Vacuum Cleaner

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner used to remove foreign matter (including water) on a floor surface by using an air pressure difference between inside and outside of a vacuum cleaner.

When cleaning indoor floors, use the air pressure inside and outside of the cleaner to suck the foreign matter (including water) from the floor into the inside of the apparatus together with the air, then selectively remove the foreign matter, and then discharge the air to the outside A vacuum cleaner that operates in a manner that allows the user to operate the vacuum cleaner is widely used.

11 is an assembled perspective view of a conventional vacuum cleaner.

11, the conventional vacuum cleaner has a hollow main body 111 in which an exhaust hole 111a and a suction hole 111b are formed, and a hollow main body 111 in which the suction hole 111b is communicated with the main body 111 A head supporting portion 160 for supporting the suction head 120 with respect to the main body 111 and a suction head 120 mounted on the main body 111. The main body 111 includes a suction pipe 113, a suction head 120 connected to the end of the suction pipe 113, And an operating portion 114. [

A wheel 112 is attached to the side surface of the main body 111.

The suction pipe 113 is formed of a flexible material to be coupled to the suction hole 111b and is formed in a straight pipe shape using a hard material to be coupled to the suction hole 120a described later.

The suction head 120 has a connection pipe 124 and a suction hole 120a is formed in a region where the connection pipe 124 is connected.

The suction head 120 having the above-described configuration is installed so that the connection pipe 124 enters the suction pipe 113. Thus, the suction head 120 is in communication with the suction pipe 113,

The head supporting portion 160 has a main body fixing bracket 161 formed on the main body 111 and a head fixing bracket 162 formed on the suction head 120.

The main body fixing bracket 161 is formed in a concave shape of an upward opening.

The head fixing bracket 162 is formed in a cantilever shape

The position where the head fixing bracket 162 is formed is selected so that the suction head 120 is spaced from the bottom surface when the head fixing bracket 162 is inserted to be inserted into the body fixing bracket 161 from the upward direction.

The suction operation unit 114 includes a fan and a motor that rotates the fan, and the suction operation unit 114 generates a pressure difference between the inside and the outside of the main body 111, which is generated when the fan is rotated, through the suction hole 120a And operates to discharge the sucked air to the outside of the main body 111 through the exhaust hole 111a.

The foreign matter contained in the air sucked through the suction hole 120a is removed by a predetermined filtering means before being discharged to the outside of the main body 111 through the exhaust hole 111a.

A method of using a conventional vacuum cleaner having the above-described configuration will be described with reference to FIG.

First, a suction pipe (113) is installed in the connection pipe (124).

Next, the suction operation unit 114 is driven to perform a cleaning operation.

When the cleaning operation is completed, the head fixing bracket 162 is engaged with the body fixing bracket 161. [

When the head fixing bracket 162 is engaged with the main assembly fixing bracket 161, the suction head 120 is separated from the bottom surface.

The suction head 120 can be easily moved while the suction head 120 is spaced from the bottom surface.

However, according to the conventional vacuum cleaner, when the head fixing bracket 162 is coupled to the main body fixing bracket 161, the suction head 120 is separated from the bottom surface, There is a problem that the head 120 can not be moved together.

As a related prior art, Korean Patent Laid-Open Publication No. 10-2009-0040016 (published on Apr. 23, 2009, entitled " Inhalation nozzle mounting device for vacuum cleaner "), A technique relating to a cleaner is disclosed.
