Description

Vacuum cleaner having a cyclone dust collector {Vacuum cleaner having cyclone dust-collecting apparatus}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner having a cyclone dust collecting device that collects and collects relatively large particles of dirt and toilet paper, vinyls and hairs, which are sucked through a suction port.

As shown in FIG. 1, a general vacuum cleaner includes a cleaner body 1, a connection hose 2 connected to the main body 1, a plurality of extension pipes 3 connected to the connection hose 2, and the extension pipe. And an inlet 4 connected to the end of (3). A cover 5 is rotatably installed on the cleaner body 1, and a connection hose 2 is connected to the cover 5. In addition, a dust collecting chamber 6 is provided inside the cleaner main body 1, and a paper filter 7 for collecting dust such as dust is housed in the dust collecting chamber 6 so as to be detachably attached thereto.

In the drawing, reference numeral 8 is a handle grip.

In the general vacuum cleaner as described above, dirt is sucked through the suction port 4 together with the suction air by a suction force by a motor (not shown) installed inside the cleaner main body 1. The suction air and the dirt sucked in this way are introduced into the cleaner body 1 through the extension pipe 3 and the connection hose 2. Here, the dirt is collected in the paper filter 7 stored in the dust collecting chamber 6 of the cleaner body 1, and the suction air is discharged to the outside of the cleaner body 1 through the paper filter 7.

However, in the general vacuum cleaner as described above, dust and dirt sucked with the air through the suction port 4 are collected in one paper filter 7 housed in the dust collecting chamber 6 of the cleaner body 1. As a result, the paper filter 7 is easily filled with dirt. When the paper filter 7 is full of dirt, the suction force is not only lowered, but also causes an overload of the motor, so that the paper filter 7 needs to be replaced. The conventional vacuum cleaner is easily filled with the dirt. By being filled, there is an inconvenience in use that requires frequent replacement of the paper filter 7.

In order to solve the problems of the general vacuum cleaner as described above, that is, the inconvenience of using the cleaner due to frequent replacement of the paper filter, a vacuum cleaner having a cyclone dust collector has been proposed. Cyclone is a device that separates particles in a fluid using centrifugal force, and has been widely used as a dust collector in industrial sites for a long time because of its simple structure and the ability to withstand high temperature and high pressure.

Such a cyclone vacuum cleaner is configured to first collect the relatively large particles of dirt sucked through the suction port before being introduced into the paper filter of the cleaner body. Therefore, the amount of dirt collected by the paper filter can be reduced, so that the paper filter can be used for a longer time. In addition, there is an advantage that the paper filter can be easily filled with dirt to prevent the lowering of suction force and the overload of the motor.

Representative examples of such cyclone vacuum cleaners include Korean Utility Model Registration No. 1993-4891 (name: vacuum cleaner with cyclone), and Korean Patent Application No. 1993-5099 (name: vacuum cleaner). .

A vacuum cleaner (utility model registration application 93-4891) provided with the former cyclone has a structure in which a cyclone capable of separating and collecting dirt can be coaxially installed in a connecting pipe of a vacuum cleaner. Here, the cyclone is an outer cylinder, an inner cylinder provided inside the outer cylinder, a hopper provided at the lower portion of the inner cylinder, a suction hose connecting the head of the cleaner and the outer cylinder, and the inner cylinder and the outer cylinder. It consists of a Volt's finder which penetrates the upper surface of a sieve, and the cyclone inlet formed in one side surface of the said inner cylinder. Such a vacuum cleaner can collect dust collected by the cyclone from the dust collected through the suction port by the cyclone, thereby reducing the amount of dust collected by the paper filter of the cleaner body.

On the other hand, the latter vacuum cleaner (patent application 93-5099) has a structure in which the sewage separation and collecting means for separating and collecting the dirt in the extension pipe connecting the cleaner body and the suction port. Here, the dust separation and collecting means, a case having a first and a second dust collecting chamber therein, a Voltes finder formed on the upper portion of the case, a connection portion formed to communicate with the first dust collecting chamber at the bottom of the case, The cyclone separator of the conical structure is stored in the case and the inner diameter gradually decreases toward the lower side, the hopper of the conical structure is coupled to the lower end of the cyclone separator, the inner diameter gradually increases toward the lower side, the middle of the cyclone separator An inlet filter coupled to the portion to separate the first and second dust chambers, a filter coupled to the upper portion of the cyclone separator and splitting the second dust chamber into two parts again, and a vortex breaker formed under the cyclone separator. It is. In this vacuum cleaner, too, large particles of dust and the like, which are collected through the suction port, are collected by the dust separation and collecting means, thereby reducing the amount of dust collected in the paper filter of the cleaner body.

However, in the conventional cyclone vacuum cleaner as described above, since the cyclone (in other examples, the waste separation means) is coaxially installed in the extension pipe of the vacuum cleaner, the cyclone or the waste separation in order to discard the waste collected therein Since the collecting means must be completely separated from the extension pipe of the cleaner, there is a problem that use is inconvenient.

In addition, the conventional cyclone vacuum cleaner has a problem in that the structure of the cyclone or the waste separation means is complicated, not only difficult to manufacture but also high manufacturing cost.

The present invention has been made in view of the above problems, and provides a vacuum cleaner having a cyclone dust collector that can easily discard the collected dust therein without completely separating the cyclone dust collector from the extension pipe of the cleaner. There is a purpose.

It is another object of the present invention to provide a vacuum cleaner having a cyclone dust collector which is simple in structure and easy to manufacture as well as low in production cost.

Vacuum cleaner according to the present invention for achieving the above object is provided in the extension pipe connecting the cleaner body and the suction port, the cyclone dust collector for separating and collecting relatively large dust and dirt sucked from the suction port of the vacuum cleaner by centrifugal force action Include. This cyclone dust collector is provided biaxially with respect to the extension pipe of the cleaner. Thereby, when discarding the waste collected separately by the cyclone dust collector, it is possible to discard the cyclone dust collector without completely removing it from the extension pipe of the cleaner.

The cyclone dust collecting device includes a cyclone body having first and second connecting pipes connected to the extension tube of the cleaner, a waste container that is detachably coupled to the cyclone body, and the waste container is attached to and detached from the cyclone body. Possibly locking means.

The cyclone body is separated into upper and lower body parts and is assembled to each other by several screws. The lower body portion is formed with an air inlet communicating with the first connecting tube, the upper body portion is formed with an air outlet communicating with the second connecting tube. The first connector is connected to the suction port side extension tube of the cleaner, and the second connector is connected to the body side extension tube of the cleaner. The air including the dirt sucked through the inlet of the cleaner is introduced in an oblique direction to the cyclone body through the air inlet of the cyclone body, thereby forming a vortex air flow inside the cyclone body. The dust contained in the air by the vortex air flow is separated from the air by the centrifugal force and collected in the waste container, and the air is discharged through the air outlet as it rises by starting the reverse upward movement at the bottom of the waste container. .

At this time, the dust and the like can be flowed back with the air through the air outlet of the cyclone body, in order to prevent this, the cyclone dust collector according to the present invention, a plurality of fine extending and installed downward from the air outlet of the cyclone body A dirt separation grill having a through hole is provided. As a result, the air rising from the waste container is discharged through the fine passage hole, but the dirt larger than the fine passage hole does not escape, and descends again and is collected in the waste container.

In addition, the lower end of the dirt separation grill is provided with a dirt blocking means for blocking the dirt rising up with the air flow up the air before reaching the dirt separation grill to reach the dirt separation grill. As a result, dirt such as toilet paper does not fully rise to the upper portion of the cyclone body, but is blocked on the way and descends again. Therefore, it is possible to significantly reduce the amount of dirt flowing back through the fine passage hole of the dirt separation grill, and to prevent the phenomenon that dirt such as toilet paper blocks the fine passage hole of the dirt separation grill.

The dirt blocking means having the above function may be configured by integrally forming a cone-shaped dirt blocking plate that increases in width from the top to the bottom at the bottom of the dirt separation grill, or separately at the bottom of the dirt separation grill. The conical dirt blocking rotary plate may be installed to be rotated by the vortex air of the air. In addition, an auxiliary blocking member may be installed at a lower end of the dirt blocking plate and the dirt blocking rotary plate. The auxiliary blocking member may be constituted by, for example, a brush, and is installed to be widely distributed while maintaining the same angle as the downward extension of the dirt blocking plate and the dirt blocking rotary plate.

On the other hand, the waste container is formed in a substantially cylindrical shape, it is necessary to have a strength that is not easily damaged by an external impact. The lower one side of the waste container is integrally formed with a support for supporting the waste container in the extension pipe when installed in the extension pipe. This support is inserted into the slide groove of the fixing ring fixed to the extension tube, and is assembled to the cyclone body by the upper part of the waste container being coupled to the cyclone body by the locking means. In addition, the waste container may be a cylindrical having a predetermined diameter, or may be a lower-shrink cylinder that becomes smaller in diameter from the top to the bottom. In addition, the waste container may be a lower expandable cylinder having a lower diameter than the upper diameter thereof. In this case, the waste container may lower the rotational speed of the air in the waste container toward the lower portion. It is effective in preventing backflow. Here, in the case of the lower expansion type waste container, it is composed of a first cylindrical portion on the upper side with a smaller diameter and a second cylindrical portion on a lower side with a larger diameter than the first cylindrical portion. As a result, the air sucked into the waste container is separated from the dust while rotating at a relatively high speed in the first cylinder portion, and rotates in a state where the rotation speed is relatively slow in the second cylindrical portion in the lower portion. Therefore, it is possible to minimize the amount of dirt collected by the waste container by piggybacking in the vortex air stream. The second cylindrical portion may have a shape in which the diameter gradually increases from the upper portion to the lower portion, and may be formed as a cylindrical body having a simple shape larger in diameter than the first cylindrical portion.

The locking means is coupled to a pair of locking holes formed on both sides of the lower body portion, a pair of rocker supports integrally formed on both sides of the upper part of the waste container, and a pair of rockers having hooks formed at the ends at the ends thereof; It is composed of a spring which is interposed between the inner end of the rocker and the rocker support of the waste container, and elastically supports the rocker in one direction. Here, each rocker is elastically supported by the spring in the direction in which its hook is caught by the locking hole of the lower body part. Therefore, when the waste container is pushed against the lower body part of the cyclone body, the locker's hook is inserted into the catch hole and the waste container is coupled to the cyclone body. When removing the waste container against the cyclone body, pull out while pressing both lockers. Then, the hook of the locker is removed from the catching hole of the lower body part, and the support part of the lower part of the waste container is detached from the fixing ring of the extension pipe, so that only the waste container can be separated and the waste collected therein can be easily discarded.

According to a preferred embodiment of the present invention, the vacuum cleaner is installed in the extension pipe connecting the cleaner body and the suction port is a cyclone dust collector for separating and collecting relatively large dust and dirt sucked from the suction port by the centrifugal force action with respect to the extension pipe It is installed by accumulation; The cyclone dust collector is provided with a first and a second connection pipe connected to the extension pipe of the cleaner, one side is formed with an air inlet communicating with the first connection pipe, the other side is an air outlet communicating with the second connection pipe Is formed, the cyclone body to form a vortex air flow with respect to the air sucked; A sewage container detachably coupled to the cyclone body and collecting sewage separated from air; A dirt separation grill extending and installed downward from an air outlet of the cyclone body, and having a plurality of fine passage holes formed therein to prevent dust and the like from flowing back to the air outlet of the cyclone body; A dirt blocking means provided at a lower end of the dirt separation grill and blocking the dirt rising together with the air by piggybacking up the airflow of the dirt before reaching the dirt separation grill; And locking means for detachably supporting the waste container with respect to the cyclone body.

According to this, since dust and dirt of comparatively large particle | grains which are sucked through the suction port, or dirts, such as toilet paper and vinyl, are collected by a cyclone dust collector primarily, the replacement | exchange period of the paper filter of a cleaner can be extended.

In addition, even when the waste container of the cyclone dust collector is full of waste, it is very convenient because the cyclone dust collector can be simply discarded by simply separating the waste container without completely removing it from the extension pipe of the cleaner.

Objects and other advantages of the present invention as described above will become more apparent by describing the preferred embodiments of the present invention in detail with reference to the accompanying drawings.

It is an assembling perspective view of the cyclone dust collector shown, and FIG. 5 is sectional drawing for demonstrating the dust collecting action of the cyclone dust collector shown in FIG.

For reference, the same reference numerals refer to the same parts as those in the related art in the configuration and operation, and detailed description thereof will be omitted, and only the characteristic parts of the present invention will be described.

Accordingly, in the drawings, reference numeral 1 denotes a cleaner body, 2 a connection hose, 3 an extension tube, 4 an inlet, 5 a cover, 6 a dust collecting chamber, 7 a paper filter, and 8 a handle grip. Reference numeral 10 denotes a cyclone dust collector which is a main part of the present invention.

As shown in FIG. 2, the cyclone dust collector 10 is connected to the extension pipe 3 connecting the cleaner body 1 and the suction port 4.

The cyclone dust collector 10 may be detachably coupled to the cyclone body 20 having the first and second connecting pipes 11 and 12 connected to the extension pipe 3, and the cyclone body 20. A waste container 30 and a locking means 40 for detachably supporting the waste container 30 with respect to the cyclone body 20.

The first and second connectors 11, 12 of the cyclone body 20 are connected to one side with respect to the center of the cyclone body 20. When the cyclone dust collector is connected to the extension pipe 3 of the cleaner by such a configuration, as shown in FIG. 5, the center axis of the cyclone dust collector, more specifically, the central axis C2 of the waste container 30 is It is not on the axis C1 of the extension pipe 3, but is located biaxially. Therefore, in order to discard the waste collected in the waste container (30), it is not necessary to remove the extension tube of the cleaner as in the prior art. That is, as shown in Figure 2, by separating only the waste container 30 in the cyclone body 20 can be easily discarded.

The cyclone body 20 is separated into a lower body portion 21 in which the first connecting pipe 11 is integrally formed, and an upper body portion 22 in which the second connecting pipe 12 is integrally formed. The upper and lower body parts 22 and 21 are coupled to each other by several screws 29.

The lower body portion 21 has an air inlet (11a) is formed in communication with the first connecting pipe (11), the upper body portion 22 is an air outlet communicating with the second connecting pipe (12) 12a is formed. Here, these air inlets 11a and air outlets 12a are formed by partitioning the inside of the upper and lower body portions 22 and 21 into curved ribs 22a and 21a, respectively. In addition, the upper and lower body portions 22, 21 are formed to correspond to each other a plurality of pairs of high information 22b (21b) having a screw hole at each predetermined position. In addition, the first connecting pipe (11) and the second connecting pipe (12) is provided with a detachable hole (11b) and a detachable protrusion (12b) for coupling with the extension pipe (3 ', 3'), respectively, Extension pipes 3 'and 3' are formed with a detachable protrusion 3'b and a detachable hole 3'b corresponding to the detachable hole 11b and the detachable protrusion 12b, respectively.

The first connecting pipe 11 is connected to the suction port side extension pipe 3 'of the cleaner, and the second connecting pipe 12 is connected to the body extension pipe 3' of the cleaner. Air containing dirt sucked through the suction port of the cleaner is introduced in an oblique direction to the cyclone body 20 through the air inlet (11a) of the first connecting pipe (11). Thereby, the vortex airflow (arrow shown by the solid line in FIG. 5) is formed in the cyclone body 20 and the waste container 30. As shown in FIG. Sludges of large particles contained in the air are separated from the air by the centrifugal force by the vortex air of such air, and the air flows upwards from the bottom surface of the waste container 30 upwardly (dotted line in FIG. 5). Arrow) is discharged toward the cleaner body 1 through the air outlet 12a of the cyclone body 20.

The waste container 30 is detachably coupled to the cyclone body 20 by the locking means 40, and forms a vortex air flow for the air introduced in cooperation with the cyclone body 20, while vortexing. The centrifugal force caused by the air flow collects the dirt separated from the air.

Such a waste container 30 is formed in a substantially cylindrical shape, but is not necessarily limited thereto. However, in consideration of the external appearance, as shown in the example, it can be formed as a lower reduction cylindrical body that becomes smaller in diameter from the top to the bottom.

In addition, the waste container 30 is preferably formed of a translucent material in order to easily identify the waste collected in the outside from the outside, but it is not necessarily limited thereto. In addition, it is preferable that the waste container is formed of a material having a certain strength so as not to be damaged when the impact container is dropped or dropped from the outside.

On one side of the outer circumferential surface of the bottom of the waste container 30, a support part 31 for supporting the waste container 30 with respect to the extension tube 3 of the cleaner is integrally formed. This support part 31 is inserted in the slide groove 32a of the fixing ring 32 provided in the extension pipe 3. The support part 31 is formed on the front of the fixing projection 31b having a locking projection 31a fixed to the slide groove 32a of the fixing ring 32 and fixed to the slide groove 31b. It is composed of a guide projection (31c) for guiding the insertion of the fixing projection (31b) to (32a). The guide protrusion 31c is formed in a shape in which the width decreases toward the front of the fixing protrusion 31b. The fixing ring 32 is fixed to the extension pipe 3 with a screw (not shown).

The locking means 40 is hinged to a pair of locking holes 41 formed symmetrically on both sides of the lower body portion 21 and a pair of rocker support portions 42 formed on both sides of the upper portion of the waste container 30. A pair of lockers 43 are coupled to the end, and a hook 43a is formed on the locking hole 41 and between the rear end of the locker 43 and the locker support 42 of the waste container 30. Interposed in the locker 43 is composed of a pair of springs 44 to elastically support in one direction.

The rocker support part 42 has a substantially 'U' shape, and a pair of hinge holes 42a and spring support protrusions 42b are formed at predetermined positions, respectively. The rocker 43 rotates forward and reverse at a predetermined angle about the hinge protrusion 43b by inserting a pair of hinge protrusions 43b formed at both sides thereof into the hinge hole 42a of the rocker support part 42. To be installed. In addition, a spring support protrusion 43c for supporting the spring 44 is formed on the inner surface of the locker 43. Here, the spring 44 elastically supports each rocker 43 in a direction in which the hook 43a thereof is caught by the locking hole 41. Therefore, when the waste container 30 is pushed against the lower body portion 21 of the cyclone body 20, the hook 43a of the locker 43 is inserted into the catch hole 41 and the waste container 30 is the cyclone body. Coupled to (20). When removing the waste container 30 with respect to the cyclone body 20, pull out while pressing both lockers 43. Then, the hook 43a of the locker 43 is pulled out of the catching hole 41 of the lower body portion 21, and the support part 31 below the waste container 30 is removed from the fixing ring 32 of the extension pipe 3. By separating only the waste container (30) can be easily discarded waste collected therein.

In the drawings, reference numeral 50 denotes a dirt separation grill. The dirt separation grill 50 serves to prevent dust and the like from flowing backward through the air outlet 12a of the cyclone body 20 during operation of the cyclone dust collector of the present invention. The dirt separation grill 50 extends downward from the air outlet 12a and is provided with a plurality of fine passage holes 50a. As a result, the air rising from the waste container 30 exits through the fine passage hole 50a, but the dirts larger than the fine passage hole 50a do not escape and fall back to be collected in the waste container 30.

Looking in more detail, the dirt separation grill 50 is formed by integrally formed with the upper grill guide portion 51, the hollow conical grill portion 52 and the lower cylindrical grill portion 3 is integrally formed, The fine passage hole 50a is formed over the entirety of the outer circumferential surface of the cylindrical grill portion 53 and the remaining portion except for a predetermined portion proximate to the air inlet 11a of the conical grill portion 52.

Such a dirt separation grill 50 is provided by the grill guide portion 51 thereof is supported by the curved ribs 22a and 21a formed on the upper and lower body portions 22 and 21. To this end, a rib groove 51a for accommodating the curved ribs 22a of the upper body part 22 is formed at an upper edge of the grill guide part 51, and a curved rib of the lower body part 21 is formed on the opposite side thereof. A stepped portion 51b to which 21a is in close contact is formed.

In addition, a conical dirt blocking plate 60 is formed integrally at the lower end of the dirt separating grill 50 from the upper part to the lower part.

The dirt blocking plate 60 performs a role of blocking the dirt that rises with the air by climbing up the air flow before reaching the dirt separating grill 50 before descending again. As a result, dirt such as toilet paper does not fully rise to the upper portion of the cyclone body 20 and is blocked in the middle and descends again. Therefore, the amount of dirt flowing back through the fine passage hole 50a of the dirt separation grill 50 can be significantly reduced, and dirt, such as toilet paper, can be used to reduce the fine passage hole 50a of the dirt separation grill 50. The blocking phenomenon can be prevented.

Hereinafter, the operation of the vacuum cleaner having the cyclone dust collector as described above will be described.

When the power is applied, suction power is generated by driving the motor mounted on the cleaner body 1, so that dust such as dust passes through the suction port together with the suction air, as shown in FIG. It is introduced into the cyclone dust collector through the. At this time, the air flowing into the cyclone dust collector is introduced in an oblique direction to the cyclone body 20 by the air inlet 11a of the first connecting pipe (11). As a result, the air starts to descend to the bottom of the waste container 30 while causing a vortex air stream. In this process, dirt containing large particles, toilet paper, and vinyls contained in the air by centrifugal force are separated from the air and descended on the inner wall of the waste container to be collected into the waste container 30. Then, the air starts the inverted upward movement at the bottom surface of the waste container 30 and the cleaner body 1 through the air outlet 12a and the second connecting pipe 12 by the air flow rising while rotating at a smaller radius of rotation. ) Is discharged to the side. At this time, the dirt that rises with the air by the air flow rising in the waste container (30) is lowered again as it does not escape the fine passage hole (50a) of the dirt separation grill (50) to the waste container (30) In addition, some relatively large dirt is collected again by falling down while hitting the dirt blocking plate (60). The dust collecting and collecting process in the cleaner body 1 is the same as a general vacuum cleaner.

When the sewage that is separated and collected by the above process is filled in the sewage container 30, only the waste container 30 is separated from the cyclone body 20 in a state where the cyclone dust collector is not separated from the extension tube of the cleaner. Discard the collected dirt.

6 is an exploded perspective view showing the configuration of a cyclone dust collector according to a second embodiment of the present invention, and FIG. 7 is a cross-sectional view for explaining the dust collecting action of the cyclone dust collector shown in FIG.

As shown, the basic configuration of the cyclone dust collector according to the second embodiment of the present invention is configured in the same manner as the first embodiment of the present invention described above. However, in configuring the dirt blocking means at the lower end of the dirt separating grill 50, unlike the first embodiment, the separate dirt blocking rotary plate 60 'is installed to be rotated by the rising air. There is a difference.

According to this, there is an advantage that the dirt blocking rotary plate 60 ′ lowers various dirts hitting while being rotated by the vortex air flow of air formed in the dirt container 30.

Here, the dirt blocking rotary plate (60 ') has a conical shape that increases in width from the top to the bottom, the shaft (60a) provided in the central portion of the upper portion of the lower surface of the dirt separation grill (50) It is provided so that rotation is possible by being fitted in the formed shaft hole. The installation structure of such a dirt blocking rotary plate can be easily configured by anyone skilled in the art.

Other configurations and operation effects are the same as those of the first embodiment of the present invention, and the same reference numerals are used for detailed description thereof.

8 is an exploded perspective view showing the configuration of a cyclone dust collector according to a third embodiment of the present invention, and FIG. 9 is a cross-sectional view for explaining the dust collecting operation of the cyclone dust collector shown in FIG.

The cyclone dust collector according to the third embodiment of the present invention as shown is characterized in that it comprises an auxiliary blocking member 70 to assist the action of the dirt blocking plate (60).

The auxiliary blocking member 70 may be configured with a brush, and is installed along the lower edge of the dirt blocking plate 60. At this time, the auxiliary blocking member 70 is installed to be widely distributed while maintaining the same angle as the downward extension of the dirt blocking plate (60).

According to this, the dirt which rises with air in the inside of the waste container 30 can be blocked more effectively.

Other configurations and operation effects are the same as those of the first and second embodiments described above, and therefore the same reference numerals are used to omit specific descriptions.

FIG. 10 is an exploded perspective view showing the configuration of the cyclone dust collector according to the fourth embodiment of the present invention, FIG. 11 is a cross-sectional view for explaining the dust collecting operation of the cyclone dust collector shown in FIG. 10, and FIG. It is sectional drawing for demonstrating the structure and dust collection action of the cyclone dust collector which concerns on 5th Example of this invention.

As shown, the basic configuration of the cyclone dust collectors according to the fourth and fifth embodiments of the present invention is the same as the first embodiment described above. However, the waste container 30 is characterized in that it consists of a first cylindrical portion (30a) of the upper portion having a constant diameter (d1) and a second cylindrical portion (30b) of the lower portion having a larger diameter (d2) than this.

According to this, the vortex airflow of the air formed in the waste container 30 has a relatively high rotational speed in the 1st cylindrical part 30a, but has a relatively slow rotational speed in the 2nd cylindrical part 30b. Therefore, it is possible to minimize the amount of dirt collected on the bottom of the second cylindrical portion 30b by piggybacking in the vortex air flow of air.

Here, as shown in FIG. 11, the second cylindrical portion 30b may be formed in a conical shape, the diameter of which gradually increases from top to bottom, and as shown in FIG. 12, the first cylindrical portion 30a. It may be formed in a cylindrical shape of a simple shape having a diameter larger than the diameter of.

Other configurations and operation effects are the same as those of the first and second embodiments described above, and therefore the same reference numerals are used to omit specific descriptions.

As described above, according to the present invention, relatively large particles of dirt and toilet paper contained in the air sucked through the inlet are collected by the cyclone dust collecting device, and thus, the paper filter of the cleaner body. The amount of dirt collected in the plant can be significantly reduced. Therefore, the replacement cycle of the paper filter can be extended.
