Description
- 1. Field of the Invention
- The present invention relates to a vacuum cleaner, and more particularly, to a filtering device for a vacuum cleaner capable of removing dust attached to a filter in operation of a cleaner.
- 2. Description of the Background Art
- In general, a vacuum cleaner is an electronic device for cleaning an indoor space such as a room, an office or the inside of a car. Undesired impurities such as dust, which exists at home or in a car can be removed by using a suction force of the vacuum cleaner.
-
FIG. 1 is a perspective view showing a structure of a general vacuum cleaner. - As shown therein, a general vacuum cleaner includes a cleaner
main body 1 and asuction head 2 connected to the cleanermain body 1 by a suction hose 3 and an extension pipe 4, to which dust and foreign substances are sucked from a floor. - The cleaner
main body 1 includes a suction force generating part (not shown) for generating a suction force and afiltering device 6 for filtering dust and foreign substances by the suction force generated from the suction force generating part. - As shown in
FIG. 2 , thefiltering device 6 is provided with aknob 8 and is detachably attached to a filtering device mounting portion 5 recessed from one side of the cleanermain body 1. Accordingly, a user can couple thefiltering device 6 to the cleanermain body 1 and separate thefiltering device 6 therefrom, more conveniently, by using theknob 8. -
FIG. 3 is a disassembled perspective view showing a filtering device of a conventional vacuum cleaner, andFIG. 4 is a longitudinal sectional view taken along line IV-IV ofFIG. 3 . - The filtering device of a conventional vacuum cleaner includes a casing 12 having a collecting space therein, a
suction opening 14 through which air including dust is sucked and adischarge opening 15 through which purified air is discharged; and afilter 13 installed at the internal space of the casing 12, for filtering dust from air sucked through thesuction opening 14. - The casing 12 includes a
body 10 formed in a cup shape an upper side of which is opened and having thesuction opening 14 at its one side; and acover 11 installed for covering the upper surface of thebody 10. - A
filter supporter 18 through which adischarge opening 15 penetrates is installed at thecover 11, and thefilter 13 is mounted at thefilter support plate 18, so that purified air is discharged outside. In addition, when thecover 11 and thebody 10 are coupled to each other, thefilter 13 is positioned inside thebody 10. - A
support wall body 16 is protruded from an inner lower portion of thebody 10 at a predetermined height. A pair of blockingplates 17 are installed to face each other at an upper surface of thesupport wall body 16, having a certain gap therebetween, so that relatively big dust or foreign substances of dust introduced into thebody 10 are prevented from escaping therefrom. - A process for collecting dust in a
filtering device 6 of a conventional vacuum cleaner will now be described. - When power is applied, a suction force is generated from a suction force generating part (not shown), and dust and foreign substances are sucked into the casing 12 through the
suction opening 14 via the suction head 3, the expansion pipe 4 and the suction hose 3. The dust sucked into the casing 12 is purified by thefilter 13 and collected in the casing 12, and only air purified while passing through thefilter 13 is discharged through the discharge opening. Here, dust or foreign substances having a relatively great weight fall to a gap between the blockingplates 17 by their weights and then are collected at an inner lower portion of the casing 12. Thesupport wall body 16 cuts off an eddy that may occur in a space under the blockingplate 17 so as to prevent dust from floating and so from moving into a space above the blockingplate 17. Fine dust or foreign substances which are relatively light are not collected in the space under the blockingplate 17 but float together with air and are purified again by thefilter 13. - However, the above-mentioned conventional vacuum cleaner has disadvantages in that the filter has to be cleaned or replaced periodically. This is because when the conventional vacuum cleaner is used for a certain period of time, fine dust is attached to the filter of the filtering device, thereby deteriorating a suction force. That is, since fine dust fills up a close mesh of the filter, it is difficult to discharge air, which is sucked through the suction opening, through the filter, and finally a decrease in suction force is caused. Accordingly, if the filter is not cleaned or replaced periodically, cleaning cannot be effectively performed due to the deterioration of the suction force.
- Therefore, an object of the present invention is to provide a filtering device for a vacuum cleaner capable of preventing a channel of a filter from being closed with dust, by self-removing fine dust attached to a filter in a cleaning operation.
- To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a filtering device for a vacuum cleaner comprising: a casing having a collecting space therein, a suction opening through which air including dust is sucked and a discharge opening through which purified air is discharged; a filter installed at the internal space of the casing, for filtering dust from air sucked through the suction opening; and a filter cleaning unit disposed to encompass an outer circumferential surface of the filter, for cleaning the filter by being rotated by a rotation force of the air sucked through the suction opening.

FIG. 5 is a disassembled perspective view of a filtering device for a vacuum cleaner in accordance with the present invention,FIG. 6 is a longitudinal sectional view taken along line VI-VI ofFIG. 5 and showing an assembled filtering device in accordance with the present invention, andFIG. 7 is a perspective view of a filter cleaning unit in accordance with the present invention. - As shown therein, a filtering device of a vacuum cleaner in accordance with the present invention is provided with a
knob 80 and detachably attached to a filtering device mounting portion 5 recessed from one side of themain body 1. Accordingly, a user can couple the filtering device to the cleanermain body 1 and separate the filtering device therefrom, more conveniently, by using theknob 80. - A filtering device of a vacuum cleaner in accordance with the present invention includes a
casing 120 having a collecting space therein, a suction opening 140 through which air including dust is sucked and a discharge opening 150 through which purified air is discharged; a filter installed at an internal space of thecasing 120, for filtering dust from air sucked through the suction opening 140; and afilter cleaning unit 200 disposed to encompass an outer circumferential surface of thefilter 130, for cleaning thefilter 130 by being rotated by a rotation force of air sucked through the suction opening 140. - The casing includes a
body 100 formed in a cup shape an upper side of which is opened; and acover 110 installed for covering the upper surface of thebody 100. - A
cylindrical filter supporter 180 through which adischarge opening 150 penetrates is installed at thecover 110, and the filter is mounted to thefilter supporter 180, so that purified air can be discharged outside. In addition, when thecover 110 and thebody 100 are coupled to each other, the filter is positioned inside thebody 100. - A
support wall body 160 having a predetermined height is protruded from an inner lower portion of thebody 100. A pair ofblocking plates 170 are installed to face each other, having a certain gap therebetween, so that relatively big dust or foreign substances of dust introduced into thebody 100 are prevented from escaping therefrom. - The
filter 130 can filter even fine dust and is formed in a cylindrical shape as to be mounted to thefilter supporter 180. - Preferably, the
suction opening 140 is eccentrically formed at one side of thebody 100 so that introduced air and dust can rotate in thecasing 120. - The
filter cleaning unit 200 includes arotary ring 210 disposed to encompass an outer circumferential surface of thefilter 130; ablade 220 formed at an outer circumferential surface of therotary ring 210, for rotating and lifting therotary ring 210 by a rotation force of air sucked through thesuction opening 140; and abrush 230 mounted inside therotary ring 210, for removing dust attached to the surface of thefilter 130 by being rotated together with therotary ring 210. - Preferably, the
rotary ring 210 is formed in a round ring shape having a predetermined width and is made of light material such as plastic so as to be easily rotated and lifted. - The
blade 220 is integrally protruded from an outer circumferential surface of therotary ring 210. In addition, preferably, at least twoblades 220 are formed at the outer circumferential surface of therotary ring 210. - In addition, the
blade 220 is inclined at a predetermined angle (θ) on the basis of an axial direction of thefilter 130 in order to rotate and simultaneously lift therotary ring 210 by air introduced through thesuction opening 140 formed at thebody 100. - In addition, a pair of
blades 220 are formed to face each other in a diagonal direction of therotary ring 210, so that therotary ring 210 can be stably rotated. That is, preferably, a pair ofblades 220 are formed in a diagonal direction of therotary ring 210 so that the center of gravity of therotary ring 210 does not become eccentric. In addition, in view of a design condition, several pairs of blades may be formed in diagonal directions of therotary ring 210, or a plurality ofblades 220 may be formed at an outer circumferential surface at regular intervals. -
FIG. 8 shows a modified example of ablade 220 in accordance with the present invention. As shown therein, ablade 220 formed at an outer circumferential surface of therotary ring 210 is formed in a curved shape, so that therotary ring 210 can be rotated and lifted much more efficiently. - The
brushes 230 are protruded at regular intervals from an inner circumferential surface of therotary ring 210 toward the center of therotary ring 210. - As shown in the drawing, preferably, four brushes are installed at intervals of 90°. However, in view of the design, more than four
brushes 230 may be formed by pairs to face each other, or only twobrushes 230 may be formed to face each other at the inner circumferential surface of therotary ring 210 at an interval of 180°. In addition, thebrushes 230 may be successively formed at the entire inner circumferential surface of therotary ring 210, facing the center of therotary ring 210. - An operation of the filtering device for a vacuum cleaner in accordance with the present invention will now be described.
- When a fan-motor of a vacuum cleaner is operated, and a suction force work in the
casing 120 of the filtering device, dust or foreign substances sucked through the suction head of the cleaner are sucked into thecasing 120 through thesuction opening 140 formed at one side surface of thecasing 120, together with air. Big dust or foreign substances of the dust or foreign substances sucked in such a manner fall by self-weight and are collected at an inner lower portion of thecasing 120 divided by the blocking plate 105. Only fine dust is discharged toward thedischarge opening 150 together with air. Dust in the air discharged toward thedischarge opening 150 is filtered by thefilter 130, and only filtered air is discharged through the discharge opening 102. - In addition, the
rotary ring 210 is rotated and simultaneously lifted by a rotation force of air introduced from the inner side surface of thecasing 120 through thesuction opening 140, which is applied to theblade 220 formed at an outer circumferential surface of therotary ring 210 of thefilter cleaning unit 200. Thebrush 230 installed inside therotary ring 210 is rotated together therewith, thereby removing dust attached to an outer surface of the filter 103. - That is, when the vacuum cleaner performs a cleaning operation, the filter-
cleaning unit 200 encompassing the outer circumferential surface of thefilter 130 is operated. Dust attached to the outer surface of the filter 103 is removed by the operation of the filter cleaning unit 104, so that a rapid decrease in suction force due to a channel closed with dust attached to the filter 103 can be prevented. -
FIGS. 9A to 9C are operational views showing that a filter is cleaned in accordance with the present invention. As shown therein, thefilter cleaning unit 200 rises and falls according to a cleaning mode to thereby remove dust. When a suction force of a cleaner is weak, thefilter cleaning unit 200 is rotated at a lower end portion of the filter 103 as shown inFIG. 9 a, thereby removing dust attached to an outer surface of thefilter 130. When a suction force is normal, thefilter cleaning unit 200 is rotated at a central portion of thefilter 130 as shown inFIG. 9B . When the suction force is strong, thefilter cleaning unit 200 is rotated at an upper end portion of the filter 103, thereby removing dust attached to the outer surface of thefilter 130. That is, in general, when a user uses a cleaner, changing a cleaning mode, thefilter cleaning unit 200 is rotated at the outer surface of the filter and moves upwardly and downwardly, thereby removing dust attached to thefilter 130. - As so far described, in the filtering device for a vacuum cleaner in accordance with the present invention, a filter cleaning unit is rotated, falling and rising by a rotation force of air sucked into an internal space of the casing, thereby cleaning the outer circumferential surface of the filter. Hence, even if the cleaner is operated for a long time, flow resistance of air passing through the filter is reduced. Accordingly, a sudden deterioration of a suction force of a cleaner is prevented from occurring so that efficiency of a cleaner is remarkably improved.
- As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
