Vacuum Cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of removing dust from a filter part for filtering fine dust from the air discharged from the dust separation part from the filter part, and guiding the removed dust to the dust collecting part. It is about.

A vacuum cleaner is an electric device that can remove dust and other foreign substances from the floor or furniture of a building by using a mechanism that sucks external air using a vacuum pressure.

Such a vacuum cleaner is divided into a canister method in which a main body and a suction nozzle are separated and connected by a predetermined tube, and an up-right method in which the suction nozzle and the main body are provided as one type.

In general, the vacuum cleaner is characterized by a suction nozzle, a dust separator that separates the air and foreign substances introduced from the suction nozzle by a cyclone principle, and discharges purified air, and dust separated from the dust separator. It includes a dust collecting unit for collecting the filter unit for filtering the air discharged from the dust separation unit once again, and a vacuum motor for forming a vacuum pressure.

When the user operates the vacuum cleaner under such a configuration, the air and the foreign matter passing through the suction nozzle rotate in the dust separation unit, while the mass of the foreign matter is introduced into the dust collector by the centrifugal force.

The air purified by the dust separator passes through a filter unit disposed adjacent to the dust separator. Fine dust is filtered out of the filter part, and the air moves in the vacuum motor direction.

By the way, in the conventional vacuum cleaner, in order to remove the fine dust in the filter part, there was the trouble of removing the filter part from the vacuum cleaner main body and cleaning the filter part.

The present invention is to solve this problem, it is possible to remove the dust from the filter unit for filtering the fine dust in the air discharged from the dust separation unit from the filter unit, to provide a vacuum cleaner that can guide the removed dust to the dust collecting unit Its purpose is to.

The present invention for achieving this object, the dust collector is detachably provided in the main body; A dust separator provided in the dust collector and separating dust and air and discharging air; A dust collector disposed adjacent to the dust separator to collect dust; A filter unit disposed adjacent to the dust separation unit and provided at a discharge unit of the dust separation unit; A foreign material removal unit disposed between the filter unit and the dust separation unit and provided to be in contact with the filter unit and movable to the filter unit to remove foreign matters from the filter; It is provided in the dust separation unit, provides a vacuum cleaner comprising a guide unit for guiding the foreign matter separated from the filter unit to the dust collector.

In addition, the present invention and a dust collector detachably provided in the main body; Dust separation unit provided inside the dust collector and separates dust and air, and discharges air; A filter unit provided at the discharge side of the dust separation unit; A dust collector provided inside the dust collector and adjacent to the dust separator; A dust compression unit that is movable in the dust collecting unit and collects collected dust to compress the dust; A driving motor connected to the dust compression unit to drive the dust compression unit; It is provided to be in contact with the filter, and is connected to the drive motor to remove the foreign matter that is impacted to the filter unit to remove the foreign substances present in the filter unit by operating simultaneously with the dust compression unit by the drive of the drive motor. It provides a vacuum cleaner comprising a portion.

According to the present invention it is possible to automatically remove the fine dust or foreign matter on the filter provided on the dust collector.

Specifically, fine dust removal is automatically performed because the foreign material removing unit can be driven using a driving motor for driving the dust compression unit. At the same time, the dust can be compressed in the dust collector, so that fine dust can be removed and compressed quickly.

Therefore, the necessity of removing and cleaning the filter part from the main body in order to clean the filter part disappears, thereby improving user convenience.

As shown in FIG. 4, the dust separation and collection operations in the embodiment described with reference to FIGS. 1 to 3 are as follows.

After dust and air pass through the suction port by the vacuum pressure, the dust is introduced into the dust collector 100.

Dust and air form a swirl flow that rotates about the dust separator 110 within the dust collector 100, and heavy dust moves along the inner wall of the dust collector 100, and collects in the dust collector. (Arrow D).

Then, the air separated from the dust passes through the air access hole 111 of the dust separation unit 110, passes through the filter unit (arrow A). The filter unit filters the fine dust included in the air, and thus, the fine dust or foreign matter is present in the filter unit 130.

As such, after separating the dust and air, if the drive motor 520 alternately rotates the rotary shaft 450 clockwise and counterclockwise, the compression plate 401 of the dust compression unit and The foreign material removing unit 300 rotates.

That is, the compression plate 401 moves to the fixed plate 410, collects dust between the fixed plate 410 and the compression plate 401, and compresses to form a lump.

On the other hand, the extension part 301 of the foreign material removing unit 300 is rotated in a clockwise and counterclockwise direction about the rotation axis 450, accordingly, is provided on the upper surface of the extension part 301 The contact unit 302 continuously applies an external force to the filter unit 130 to separate the fine dust provided in the filter unit 130 from the filter unit 130 (arrow MD).

The fine dust or foreign matter separated from the filter unit 130 falls on the guide inclined surface 201 and moves to the discharge hole 202 by the guide of the guide inclined surface 201.

The fine dust or foreign matter moved to the discharge hole 202 falls to the dust collecting part 120 and, in particular, falls to the space surrounding the fixing plate 410 or surrounded by the fixing plate 410 and is collected.

5 shows an embodiment different from that of FIG.
