First, the air purifier according to an embodiment of the present invention is characterized in that it comprises a rotary brush that is rotated in contact with the surface of the filter assembly 11 installed in the main body case 10 as shown in FIG. To present.

That is, the present invention allows the foreign matter to be separated from the surface of the filter assembly 11 while the rotary brush sweeps off the foreign matter such as dust accumulated on the surface of the filter assembly 11 and sweeps it down. The surface cleaning of the filter assembly 11 by the automatic control, rather than the surface cleaning of the filter assembly 11 by the one is to be made.

Of course, by installing a separate mesh filter element 12 on the surface of the filter assembly 11 is configured to accumulate various dust and the like on the surface of the mesh filter element 12, the rotary brush is More preferably, it is configured to clean the surface of the mesophilic filter element 12, and in the embodiment of the present invention, the rotary brush may be used to clean the surface of the mesh filter element 12 installed on the surface of the filter assembly 11. Configured as an example.

Hereinafter, the structure of the rotating brush according to an embodiment of the present invention described above will be described in more detail with reference to FIGS. 2 to 4.

First, the rotating brush according to the embodiment of the present invention is largely configured to include a rotary wing portion 100, a pair of brush portion and the brush cover 300.

Here, the rotary vane 100 is provided on the inner wall of the front panel 20 of the air purifier, which is a portion facing the surface of the filter assembly 11 (the surface of the mesh filter body 12) in the body case 10. As a series of configurations, the center end 110 and the pair of wing ends 120 and 130 extending outward to both sides of the center end 110 to form a rotation center is formed.

In particular, the edge rim 140 is formed in the entire circumferential portion of the rotary wing 100 is configured to have an installation space therein.

In addition, a plurality of locking projections 150 are formed at the edge end 140 to protrude inwards, respectively, to prevent the brush cover 300 from being recessed and mounted in the installation space.

In addition, the pair of wing ends (120, 130) is formed to be curved in a shape that is vertically symmetric with each other toward both ends from the connection portion with the central end (110). That is, when one wing end 120 is formed convexly curved upward, the other wing end 130 is formed convexly curved downward. At this time, the curved direction is formed to have a convex shape toward the direction opposite to the rotation direction of the rotary blade 100.

This structure is to minimize the resistance due to the contact between the pair of the brush portion and the surface of the mesh-type filter body to be described later when cleaning the surface of the mesh-type filter body according to the rotation of the two wing ends (120,130) to be.

In addition, through slits 121 and 131 are formed in the pair of wing ends 120 and 130 along the longitudinal direction, respectively. In this case, each of the through slits 121 and 131 may be partially exposed to the outside of the pair of wing ends 120 and 130 (the direction opposite to the mesh filter body) and may be stable. A series of configurations for installation. Of course, each of the through slits 121 and 131 is also formed to be curved in the same shape as that of each of the wing ends 120 and 130.

Next, the pair of brush portions will be described.

The brush part is a series of components for cleaning the surface of the substantially mesh-type filter element 12, and includes a brush 210 in the form of a brush and a contact plate 220 in the form of a plate.

In this case, the brush 210 and the contact plate 220 are located at the rear ends of the two wing ends 120 and 130 constituting the rotary wing part 100, respectively, and the tip is connected to the rotary wing part 100. The through slits 121 and 131 formed at the two wing ends 120 and 130 are respectively penetrated to protrude toward the surface of the mesh filter body 12.

In addition, at the rear ends of the brush 210 and the contact plate 220, wider locking ribs 211 and 221 are formed, respectively, than the through slits 121 and 131, so that the brush 210 and the contact plate 220 pass through the brush 210 and the contact plate 220. It is configured to completely penetrate the slits 121 and 131 to be prevented from being removed forward.

In particular, in the embodiment of the present invention, the contact plate 220 is installed so as to penetrate from the rear side of the wing end 130 toward the front side, in the case of the brush 210 of the wing end 120 It is proposed to be configured to be recessed toward the inner side (side connected with the center end) from the outer side (side most spaced from the center end). This is because, in the case of the contact plate 220, there is no difficulty in directly penetrating the through slit 131, but in the case of the brush 210, since the brush 210 is made of a brush, it is difficult to penetrate the through slit 121 directly. Because there is.

To this end, the locking rib 211 of the brush 210 penetrates toward the center end 110 through an outer surface of the wing end 120 of the two wing ends 120 and 130 where the brush 210 is installed. The recessed groove 122 corresponding to the shape of the locking rib 211 is formed to be formed. That is, in the case of the brush 210, the locking rib 211 is used to be smoothly coupled to the wing end 120. This is as shown in Figure 3 attached.

In addition, in the embodiment of the present invention, the contact plate 220 is formed from the contact end 222 and the surface of the meshed filter body 12 in contact with the surface of the meshed filter body 12 along the longitudinal direction. It is suggested that the non-contact ends 223 spaced apart from each other are sequentially formed in the unevenness.

This configuration is to reduce the contact area between the contact plate 220 and the mesh-like filter body 12 so that the maximum contact resistance can be reduced.

Of course, the non-contact portion 223 is preferably formed to a width that can be scratched while the dust accumulated on the surface of the mesh filter body 12 smoothly sweep.

Next, the brush cover 300 will be described.

The brush cover 300 receives a driving force to rotate the rotary wing unit 100 and at the same time a series of stably mounted brush 210 and the contact plate 220 from the rotary wing unit 100 It is the composition.

The brush cover 300 is formed in a shape corresponding to the rotary wing unit 100 is configured to be concaved in the installation space formed by the edge end 140 of the rotary wing unit 100, the rear surface thereof A coupling end 310 for shaft coupling with a driving motor (not shown) providing a driving force is formed in the central side portion.

At this time, the brush cover 300 is prevented from being separated by a plurality of engaging jaw 150 formed along the edge end 140 of the rotary wing unit 100.

On the other hand, the rotary brush according to an embodiment of the present invention can be smoothly progressed only if the surface of the mesh filter body 12 is in close contact with the surface, the rotary blade 100 forming the rotary brush in the above-described embodiment This may cause a problem of being pushed to the rear (inner wall of the front panel) due to the close contact load when rotating in contact with the mesh-like filter body 12.

Accordingly, the embodiment of the present invention further suggests that the support protrusion 320 protrudes from the rear surface of the brush cover 300 in order to prevent the rotation of the rotary brush.

At this time, the support protrusion 320 is configured to be in contact with the inner wall surface of the front panel 20 located on the rear side of the brush cover 300.

That is, the rear side of the brush cover 300 is prevented by the contact between the support protrusion 320 and the component, thereby causing the brush 210 and the contact plate 220 of the mesh filter body 12 It can be rotated in close contact with the surface.

Hereinafter, an operation state of the rotating brush according to the above-described embodiment of the present invention will be described with reference to FIGS. 5 to 8.

First, when the cleaning performance cycle or the operation control according to the user's need for the mesh filter element 12 is made, the driving motor (not shown) is driven.

Accordingly, the brush cover 300 is axially coupled with the driving motor and the rotation of the rotary wing unit 100 is performed.

In this case, the brush 210 and the contact plate 220 constituting the rotary brush are in contact with the surface of the mesh-type filter body 12, the rotation operation is made.

At this time, the brush 210 is dropped while sweeping the dust accumulated in the corresponding portion from the surface of the mesh-type filter body 12 in a state in contact with the surface of the mesh-type filter body 12, thereby causing the dust Are moved along the direction of movement of the brush 210 while forming a state of being agglomerated with each other.

In addition, since the contact plate 220 passes through the place where the brush 210 has passed, the brush 210 has been separated from the surface of the mesh filter body by the brush 210, but is swept along the brush 210. Part of the dust bundle that has not gone is swept away by the contact plate 220.

In addition, when the positions of the brush 210 and the contact plate 220 are rotated beyond the vertical direction, the aggregated dust is dropped to the bottom by its own weight. Of course, even in this process, the bundle of dust that did not fall down is continuously swept away by the brush 210 and the contact plate 220, the fall is made.

In addition, the support protrusion 320 protruding from the back of the brush cover 300 during the above-described series of processes to prevent the rotary brush from being pushed to the rear side in contact with the inner wall surface of the front panel 20. do.

Accordingly, the brush 210 and the contact plate 220 constituting the rotating brush are always in contact with the surface of the mesh filter body 12, and thus the surface of the mesh filter body 12 is maintained. Cleaning can be done smoothly.
