Contact plate 432 includes many of the contact ends 432a made with the possibility of contact with the mesh body 320 of the filter, and many non-contact end 432b, located at a distance from the mesh body 320 of the filter. The contact ends 432a and the corresponding contact ends 423b continuously alternate with each other.

The width of the contact ends 432a, preferably, greater than the width of avoidant all 432b. This is done with the objective as minimizing the area of contact between the contact plate 432 and net housing 320 of the filter, and effectively wipe dust from the surface of the mesh body 320 of the filter.

A rotating device 420 of the blade and the device 430 brushes also have the following structure: a pair of blades 422 and 423, form is their rotating device 420 blades, contain end-to-end slots 422a and 423a, educated in them, respectively. The front part of the brush 431 and the contact plate 432 pass through the corresponding through slots 422a and 423a to partially extend on the outer side. The rear part of the brush 431 and the contact plate 432 contain resistant ribs 431c and 432c, having a width that is defined in such a way that they do not pass through the corresponding through slots 422a and 423a.

This design ensures that the device 430 brush remains stably mounted on a rotating device 420 blade.

In accordance with the embodiment of the present invention, the contact plate 432 is installed to pass through the second blade 423 from the rear surface to the front surface, and brush 431 is installed to pass through the side wall of the first blade 422 for insertion into the inner portion of the first blade 422. The reason for this is that although the contact plate 432 can easily pass through the through slot 423a, it is very difficult to brush 431 passed through a through slot 422a in such a direction that leaves the brush 431.

Therefore, the first blade 422 includes an installation hole 422b formed on the outer surface in the cross-sectional shape corresponding to the cross-sectional shape of the thrust rib 431c brush 431, so that the emphasis is th edge 431c may be inserted into the installation hole 422b and pass through it. In other words, brush 431 is connected with the first blade 422 by inserting the thrust ribs 431c in the installation hole 422b to pass through it.

Cover 440 brush connected with the rear surface of the rotating device 420 blades to prevent disconnection device 430 brush.

The closing plate 530 is installed to cover the area between the two reference edges 312a and 312b.

Hard protrusions 510 are along one edge 312a of both edges 312a and 312b, through which the device 400 brush is first on the direction of rotation of the device 400 brush (the clockwise direction in the drawings). Hard protrusions 510 are toothed shape (i.e., the projections and recesses alternating with each other).

Specifically, the discharge guiding device 500 is formed on the Central area of the lower part of the cover 510 of the filter to minimize plot hole 313 through which pass the falling foreign matter, so that as they pass in the node 300 of the filter are not shed into the environment.

Dust collection device 600 has a shape of a box with an upward opening and inserted into the lower branch of the node 300 of the filter around the front side with the possibility of selective removal.

While various constructions can be used to connect/detach the dust collection device 600 corresponding to the mounting device (for example, two magnets or a magnet and a metal element), preferably installed on the rear surface of the dust collection device 600 and the front surface of the body 311 of the cover forming the cover 310 of the filter corresponding to the o so they can easily connect to each other or disconnected from each other.

Next will be described processes control the operation of the cleaner in accordance with the embodiment of the present invention.

In the case of a control operation for cleaning the air in the room, based on user needs, the air cleaner is actuated to clean the air in the same manner as known to the cleaners.

Specifically, the device for suction air is driven to generate power for the suction air, which sucks air from the room into the main body 100 through the intake holes 11 formed on both side surfaces of the main body 100. Then, the air passes through the node 300 of the filter in the main body 100, and the cleaned air is produced in the internal environment through the vent hole 12 formed on the upper surface of the main body 100.

When the air passes through the node 300 filter, mesh body 320 of the filter and the other filter housing remove foreign matter (e.g. dust) and odors from the air.

If the cleaner does not work after the above series of processes, or when the user interrupts, the device for sucking air off and the air more n the passes.

Then, the rotating device 400 brush cleans the surface of the mesh body 320 of the filter on the front surface of the cover 310 of the filter.

Specifically, the drive motor comprising a rotating device 400 brush is driven to rotate the rotating device 420 blade. Then, brush 431 and the contact plate 432 to rotate while maintaining contact with the surface mesh of the body 320 of the filter and wash foreign matter from the surface, as shown in Fig.7-10.

More specifically, the brush 431 rotates in contact with the surface mesh of the body 320 of the filter so that dust that have accumulated on the surface is removed and unloaded. As a result, a large amount of dust is moved along the brush 431.

Contact plate 432 is followed by brush 431 and re-captures some of the particles that were separated from the surface of the mesh body 320 of the filter brush 431, but were not captured by the brush 431.

As a result, foreign matter (e.g. dust) are mixed in the total weight and move in the direction of rotation of the brush 431 and the contact plate 432. When foreign substances reach the area, which formed lots of hard protrusions 510, forming a discharge guiding device 500, they stop spinning and fall.

Although some particles may pass chere is C resistant protrusions 510, they linger thrust rib 520 and fall vertically instead continue to capture brush 431 and the contact plate 432.

Foreign matter falling after separation from net housing 320 of the filter is collected in the dust collection device 600, located in the lower part.

The user only has to empty dust collection unit 600, when you need it. This operation completes the cleaning of the surface mesh of the body 320 of the filter.

Specialists in the art should be understood that the cleaning of the surface mesh of the body 320 of the filter is not required when the unit is not running or when it is turned off.

This means that rotating the device 400 brush can operate to clean the surface mesh of the body 320 of the filter, even when the air cleaner is actuated to clean the air in the room.

The reason is that the space between the thrust protrusions 510 and thrust rib 520, forming a discharge guiding device 500, closed by a closing plate 530, so that the flow of dust falling into the dust collection unit 600 through the corresponding site is not disturbed.

In addition, it is possible to measure the amount of dust that have accumulated on the surface of the mesh body 320 of the filter before you begin rotating device is 400 brush. In this case, the rotating device 400 brushes managed to clean the surface mesh of the body 320 of the filter only if the amount of dust exceeds the threshold value.

This is possible because the newly created air purifiers are usually equipped with sensors to measure the amount of dust or sensors to detect odors.
