Description

A device for avoiding the obstruction in a cyclone type dust collector of a vacuum cleaner}

The present invention relates to a cyclone dust collector for a vacuum cleaner, and more particularly, to an apparatus for preventing clogging of a cyclone dust collector for a vacuum cleaner for preventing a discharge pipe from being blocked by a flow path sucked in the cyclone dust collector for a vacuum cleaner. It is about.

In general, a vacuum cleaner is a home appliance that generates a strong air suction input in a cleaner body to force the suction of contaminants such as dust on the floor to be cleaned.

Meanwhile, a general vacuum cleaner is configured to collect contaminants such as dust sucked through an extension tube in the cleaner body, but a vacuum cleaner (hereinafter, referred to as a cyclone vacuum cleaner) equipped with a dust collector using a cyclone principle is used. The dust collector is installed between the extension tube and the extension tube divided into two to collect dust and the like by using the cyclone principle.

An example of a dust collector of a conventional cyclone vacuum cleaner as described above will be described with reference to FIGS. 1 and 2 in the accompanying drawings.

In the conventional cyclone dust collector, as shown in FIG. 1, the cyclone dust collector is connected to the rear end of the inlet extension pipe 1a into which air and contaminants are introduced and is sucked through the connection pipe 1a. A suction tube 10 for guiding into the apparatus, a cylindrical first dust collector 20 in which air and contaminants guided by the suction pipe 10 are pivoted and the pollutants are collected by centrifugation, and the first dust collector ( 20 is formed on the upper portion of the configuration including a cylindrical second dust collecting member 30 is first suctioned by the air and pollutants are filtered through the first dust collecting body 20.

On the other hand, the upper part of the first dust collector 20 to filter the contaminants of the large size among the air and contaminants introduced into the first dust collector and then discharged to the second dust collector 30, the second dust collector ( 30) The hollow perforated tube 40 is formed in communication with the lower end, the perforated tube 40 is formed with a plurality of holes 41 having a predetermined diameter arranged at a predetermined interval, thereby causing a large particle contaminants Is not discharged from the first dust collecting body 20 can be collected.

On the other hand, the second dust collecting body 30 is in communication with the perforating pipe 40 of the upper end of the first dust collecting body 20 at the bottom of the first dust collecting body 20 of the perforated pipe 40 Inlet 31 through which air and fine contaminants pass through the holes 41 and air and fine contaminants passing through the inlet 31 above the inlet 31 are formed along the inner wall of the second dust collector 30. A turning force applying means 32 for applying a turning force to turn, an air discharge pipe 33 formed to communicate with the discharge side extension pipe 1b on the opposite side of the turning force applying means 32, and the lower portion of the air discharge pipe 33; It is formed to be in communication with the bottom of the second dust collecting body 30, and comprises a micro-polluting dust collector (34), which collects micro contaminants formed integrally behind the first dust collecting body (20).

The cyclone dust collecting device having the above configuration operates as follows.

When the user operates the cleaner by applying power, air and contaminants are sucked through the inlet extension pipe 1a and flow into the first dust collector 20 through the suction pipe 10 of the dust collector.

As such, air and contaminants introduced into the first dust collecting body 20 are lowered while turning along the inner wall of the first dust collecting body 20, and contaminants having a relatively large weight are collected at the bottom of the first dust collecting body 20. In addition, air and fine contaminants are discharged into the second dust collecting body 30 through the inlet 31 of the perforated tube 40 and the second dust collecting body 30 at the upper end of the first dust collecting body 20.

At this time, in the process of discharging air and fine contaminants through the hole 41 of the perforated pipe 40, the large contaminants to the perforated pipe 40 by the hole 41 of the perforated pipe 40 Since it does not get caught, only air and fine contaminants can be discharged through the other hole (40).

On the other hand, fine contaminants of the air and fine contaminants introduced into the second dust collecting body 30 through the other hole pipe 40 is affected by the turning force applying means 32 to the inner wall surface of the second dust collecting body 30. While moving along the turn and collected in the micro-contaminant dust collector 34 communicated to the bottom of the second dust collector 30, the air which is hardly influenced by the centrifugal force is discharge pipe 33 formed on the rear wall of the second dust collector 30. Is discharged to the discharge side extension pipe (1b) through.

As described above, the separation of air and contaminants in each dust collector 20 and 30 is possible due to the difference in centrifugal force due to the mass difference between air and contaminants, that is, F = meω ² (F; Centrifugal force, m; mass, e; radius of rotation, where air from the center of the dust collector dust collector to the inner wall surface, ω; angular acceleration, has almost no mass, but has a relatively large mass of dust. B. Contaminants may be collected in a dust collector installed in communication with the dust collector while continuously turning along the inner wall surface of the dust collector 20 and 30 under the influence of the centrifugal force.

In addition, the air which is hardly subjected to centrifugal force can be introduced into the cleaner body (not shown) through the discharge pipe by the suction force generated through the discharge pipe.

However, in the conventional dust collector having the same structure and function as described above, as shown in the enlarged portion A of FIG. 1 and a cross-sectional view thereof in FIG. 2, a perforated pipe 40 installed on the upper portion of the first dust collector 20. Since a plurality of holes 41 are formed in the side wall portion of which the surface is flat, air is introduced through the hole of the perforated pipe 40 when a large and light vinyl is introduced into the first dust collector 20. In the discharge process, a contaminant such as vinyl is in close contact with the other hole 40 to block the holes 41.

Accordingly, the amount of air introduced through the other hole 40 is reduced to reduce the efficiency of cleaning, or there is a problem that the entire air flow is blocked.

Accordingly, the present invention is to solve the above problems, to provide a clogging device for preventing the clogging of the cyclone dust collector for vacuum cleaners that can prevent the other hole in the cyclone dust collector by clogging during cleaning. There is a purpose.

In order to achieve the above object, the present invention, the suction pipe for guiding the air and contaminants sucked through the connecting pipe into the dust collecting device, and the air and contaminants guided by the suction pipe is rotated and the contaminants are collected by centrifugation Cylindrical first dust collector and cylindrical second dust collector which communicates with the first dust collector and collects the pollutants secondarily by centrifuging air and pollutants introduced through the first dust collector using the cyclone principle. A plurality of sieves are disposed on one side of the first dust collector at a portion where the first dust collector and the second dust collector are in communication with each other, and a plurality of side surfaces of the sieve and the second dust collector are prevented from being discharged to the second dust collector. It consists of a perforated tube having a hole formed therein, and is divided into an extension tube which is a passage through which air and contaminants flow from the outside of the vacuum cleaner. In the cyclone dust collector which is mounted on the cyclone dust collector and collects contaminants using the cyclone principle, protrusions protruding outside the perforated pipe are formed between the holes of the perforated pipe, thereby preventing the contaminants from coming into close contact with the perforated pipe. To prevent the clogging of the cyclone dust collector for the vacuum cleaner to prevent the passage from being blocked.

Hereinafter, an embodiment of the flow path blocking apparatus of the cyclone dust collector according to the present invention will be described in detail.

Therefore, as described above, a plurality of protrusions 420 are formed at a predetermined interval on the outer surface of the perforated pipe 40, so that air is discharged toward the second dust collecting body 30 through the holes 41 of the perforated pipe 40. Even if contaminants such as vinyl adhere to the surface of the perforated tube 40 in the process, the space between the contaminant and the perforated tube 40 may be separated even if the contaminants fall off or remain attached to the surface by the protrusions 420. Formed to secure a space for the air flow can be prevented that the contaminants are in close contact with the hole (40) to block the hole 41.

On the other hand, the present invention is not limited to the above-described embodiment, and various changes and implementations may be made without departing from the gist of the present invention.

According to the present invention as described above, since the projection is formed on the surface of the other hole is not contaminated with contaminants, the phenomenon that the other hole is blocked by the contaminants during cleaning can be prevented, thereby improving the efficiency of cleaning There is.
