Description

Vacuum cleaner with additional cleaning device using exhausiting wind}

The present invention relates to a cleaning structure for improving the cleaning efficiency by using the rear wind discharged from the vacuum cleaner into the atmosphere.

More specifically, the back wind of the vacuum cleaner which recovers the back wind discharged into the atmosphere through the rear part of the main body to be discharged toward the object to be cleaned from the outside of the inlet of the brush body, so that the dust and foreign matter adhered to the object is excellent. It relates to a cleaning structure using.

In general, as shown in FIGS. 1 and 2, the vacuum cleaner includes a suction motor 20 as a driving source, a dust bag 30 as a dust collecting means, and a filter 40 and 50 in the main body 10. A suction pipe 60 is connected to the suction port 11 to serve as a suction passage of dust, and the suction pipe is formed to be flexible.

In addition, an extension pipe 70 for guiding the dust to be sucked is connected to an end of the suction pipe 60, and a brush body 80 is mounted at the end of the extension pipe to improve the suction efficiency by scraping dust accumulated on an object. .

In addition, a power control terminal 90 having a power switch 91 and a handle 92 is connected between the suction pipe 60 and the extension pipe 70, and the power switch 91 is the suction motor 20. Power on and off and at the same time adjust the suction power.

In addition, the vacuum cleaner is equipped with a dust meter (Dust Meter) to display the dust collection amount on the top of the main body, and a brush neck is installed between the extension tube and the brush body to facilitate the detachment of the brush body.

When the user operates the suction motor 20 in the main body through the power switch 91 of the power control stage 90, the vacuum cleaner lowers the pressure in the main body at the same time as the operation of the suction motor, the suction force is generated, The suction force acts on the brush body 80 through the suction pipe 60, the power control end 90, and the extension pipe 70.

Therefore, external dust (foreign matter) is sucked through the inlet of the brush body 80 together with air, and the sucked dust is again passed through the extension pipe 70, the power control end 90 and the suction pipe 60, the main body 10 Is sucked into the suction port 11 of

The dust sucked into the main body 10 is first accumulated in the dust bag 30, and the dust (differential) is filtered again while passing through the filter 40 between the dust bag 30 and the suction motor 20. Next, the dust is completely filtered while passing through the filter 50 at the rear of the suction motor and is discharged into the atmosphere through the outlet 12 at the rear of the main body 10.

The vacuum cleaner is cleaned by repeating the above operation, and if the same operation is repeated to accumulate an appropriate amount of dust in the dust bag 30, the user can not see this, so the dust indicator mounted on the main body displays it externally. Then, the user visually checks the dust collection amount through the viewing window to replace the dust bag.

The dust bag can be removed from the main body, cleaned or dusted off and reused.

As described above, the conventional vacuum cleaner has two filters (40, 50) installed on the dust bag (30) and the front and rear surfaces of the suction bag with the air sucked into the main body (10) together with the dust by the suction force of the suction motor (20). After passing through the dust is filtered is a structure that is discharged into the atmosphere through the outlet 12 of the rear portion.

However, the vacuum cleaner having such a structure does not matter to clean the flat bottom surface because only one suction port is formed in the center of the brush body 80, but when cleaning a soft and flexible object such as cloth or fabrics It is attached to the brush body 80 by the suction force to block the suction port because the cleaning efficiency is lowered, there is a disadvantage that the noise is caught by the overloading of the suction motor 20 more than necessary.

In addition, if the filter 40, 50 is used for a long time or the performance of the filter is degraded, the collection effect is also reduced so that the unclean air is discharged through the outlet 12, there was a closed end causing contamination of the indoor air.

In addition, since the performance of the vacuum cleaner depends on the capacity of the conventional vacuum cleaner, the capacity of the suction motor is larger than necessary, so that the economic efficiency is lowered, and there is a problem of adding noise.

The present invention has been devised to solve this problem, and its purpose is to guide the blowing air emitted into the atmosphere through the outlet of the main body toward the brush body, so that it can be sprayed to the object to be cleaned from the outside of the inlet, so that a small amount of suction motor The present invention provides a vacuum cleaner that can effectively clean dust accumulated in cloth or textiles.
