Description

Dust suction device of vacuum cleaner {A SUCTION MEANS OF A VACUUM CLEANER}

The present invention relates to a dust suction device of a vacuum cleaner, and more specifically, by using a dust container and an inclined filter means without using a dust bag, dust or garbage particles are scattered through strong air spraying from the dust suction hose. It relates to a dust suction device of a vacuum cleaner to be filled in a separate storage space in the dust container.

In general, vacuum cleaners are the most common household appliances as tools for cleaning at home. However, since vacuum cleaners generally use a dust bag for storing inhaled dust or particles, it is very inconvenient to replace the dust bag and there is an inconvenience of purchasing and using the dust bag.

In addition, the dust bag provided as a consumable part of the vacuum cleaner is inconvenient to be manufactured separately according to different spaces and its internal structure according to the manufacturer and application model of the vacuum cleaner. In addition, when the dust bag is replaced, it is cumbersome to purchase a dust bag of a standard suitable for the manufacturer of the vacuum cleaner and its application model. In addition, when it is impossible to purchase a dust bag to find, there are many inconveniences in using the vacuum cleaner until the dust bag is purchased.

Referring to the vacuum cleaner in more detail, Figure 6 is a perspective view of a vacuum cleaner using a conventional dust bag, Figure 7 is a schematic diagram showing the operation of replacing the dust bag in the conventional vacuum cleaner in order, Figure 8 is a schematic diagram showing the dust stacking state of the dust bag used in a conventional vacuum cleaner.

As shown in FIGS. 6 and 7, the conventional vacuum cleaner sucks dust or various wastes from the brush by operating a motor (not shown) inside the main body 20, and the sucked wastes are dusted through the hose 11. The envelope 13 is filled in. As such, when the garbage is full, the dust bag 13 should be replaced with a new dust bag about once every three months, and the replacement method is illustrated in FIG. 7.

First, the dust bag support 33 is separated from the dust bag accommodating part 31 installed inside the main body 20 (FIG. 7A), and then the dust bag 13 filled with garbage is removed from the separated support 33. (FIG. 7B). Thereafter, after inserting the new dust bag 13 'into the support base 33, the dust bag support base 33 is attached to the dust bag housing 31 (FIG. 7C).

The dust bag must be replaced every three months. If the vacuum cleaner is a long time old model, it may be difficult to obtain a dust bag suitable for the vacuum cleaner.

In addition, as shown in Figure 8, when looking at the stacking state of the dust or rubbish stacked in the conventional dust bag 13, the dust from the edge (A portion) of the inlet, which is the lowest speed of the intake air The rubbish is laminated, then laminated on the edge portion (B portion) on the motor side, and finally laminated on the other space portion. In this stacking sequence, even if a strong suction force occurs in the motor, dust or garbage does not accumulate on the inner wall of the dust bag, and high-speed air and garbage continuously sprayed from the hoses scatter or blow dust or rubbish on the inner wall. The dust and garbage are scattered from the edges of the inlet where the air velocity is low.

Therefore, there has been a continuous need for users to use a vacuum cleaner that does not use a dust bag, which is inconvenient in use, and the applicants of the present invention utilize the above-described lamination principle to use a vacuum cleaner that does not use a dust bag. It was developed.

An object of the present invention is to provide a dust suction device for a vacuum cleaner that can eliminate the inconvenience to replace the dust bag by reducing the use of the dust bag and reduce the cost of using the dust bag.

Another object of the present invention by forming the filter means in the dust container in an inclined structure (for example, conical, triangular pyramid, square pyramid) by pushing the filter means to prevent dust or rubbish stacked on the filter means by the air speed sucked filter clogging It is to provide a vacuum cleaner that can prevent the phenomenon and can be used semi-permanently.

As shown in FIG. 5, the dust suction device 100 of the vacuum cleaner according to the first embodiment of the present invention operates by first inserting a power plug 410 into an outlet (not shown) to turn on the vacuum cleaner. The dust or various wastes that pass through the brush 500 by the suction force of the motor unit 180 and move to the adapter 300 via the extension pipe 510 and the hose 330 are filtered through the adapter 300. ) And injects powerful air with dust. The high-speed air injected by the filter means 110 pushes out dust or rubbish deposited on the conical filter means so that dust does not accumulate in the filter means 110, and dust or particles are scattered to open the opening 145. Stacked in the dust container 120, the scattered dust or rubbish is moved upwards along the inner circumferential surface of the partition 130 to move to the opening 145 somewhat lower air speed and then fall to the dust container ( 120).

In addition, the inner circumferential surface of the adapter 300 is formed with a gushing portion 320 so that the vortex of the air occurs, heavy particles such as small stones move along the edge of the hose by the centrifugal principle and finally the filter means It will bounce out of the 110. Thus, the filter means 110 can be used semi-permanently for a long time without fear of being damaged by hard materials such as stones.

On the other hand, in order to remove the dust or rubbish accumulated in the dust container 120, first remove the adapter 300 from the main body 400, then release the locking means 150, grab the handle 170 and the dust container ( Pull 120) toward the front of the body. Thereafter, the cap 160 is opened, the partition wall 130 is separated from the dust container 120, and then dust or rubbish stacked on the dust container 120 is removed. Thereafter, after assembling the dust container 120 in the reverse order, it is coupled to the main body 400.

In addition, the operation of the dust suction device 200 of the vacuum cleaner according to the second embodiment of the present invention will be described.

First, when the motor 280 is operated by the supply of power, dust or garbage is sucked through the adapter 300 mounted to the insertion hole 263, and the dust or garbage deposited on the filter means 210 is pushed out and scattered. Let's do it. Scattered dust or debris flows along the inner wall surface of the concave portion 235 to allow the interior of the dust container 220 to pass through the first, second, and third inlets 221, 223, and 225. Inflow into and stacked.

On the other hand, in order to remove the stacked dust or rubbish, the adapter 300 is removed from the insertion hole 263, and the outer case 260 is separated from the dust container 220. Thereafter, the dust container 220 may be inverted and shaken to remove dust or garbage therein.

As described above, the dust suction device according to the present invention is a method in which dust is accumulated by falling from above, and may have various shapes, and its mounting position may be variously changed as necessary.

As mentioned above, the dust suction device of the vacuum cleaner according to the present invention does not use the dust bag, thereby eliminating the inconvenience of periodically changing the dust bag and reducing the cost of replacing the dust bag. The advantage is that you can.

On the other hand, while the above has been described with reference to the preferred embodiments of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention described in the claims below It will be understood that modifications and changes can be made.
