BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter cleaning system for an air cleaner and an air cleaner,

An embodiment of the present invention relates to an air purifier.

Generally, the air cleaner is a device configured to suck and purify the air in the contaminated room, and to discharge the air to the room.

BACKGROUND OF THE INVENTION [0002] Recent air purifiers are configured to purify room air by performing not only dust collection for ordinary dust and bacteria but also deodorization.

Further, when the air cleaner is operated for a predetermined period of time, a large amount of foreign matter such as dust is accumulated on the filter member, so that the function of purifying the air can not be accomplished. Therefore, the user should periodically clean the filter or replace the filter. In general, the filter is designed to be washable with water for easy cleaning.

However, in many cases, the user misses a time for cleaning the filter or replacing the filter. In this case, the air contaminated by the foreign substances in the air cleaner can not be cleaned and circulates inside the room.

In addition, the process of washing the filter with water is not only troublesome to the user, but also provides a non-biased cleaning environment, so that the user is often reluctant to clean it. As a result, according to the conventional air purifier, the air purifier does not perform periodic filter cleaning and filter replacement, and accordingly, the reliability of the product is reduced due to failure to perform the function.

The air purifier according to an embodiment of the present invention has been proposed in order to solve the above problems and aims to provide a convenience to the user by improving the structure of the air purifier so that foreign substances such as dust are easily removed from the filter .

According to an aspect of the present invention, there is provided an air purifier including: a main body portion having an air suction portion; A suction device provided inside the main body part and providing a driving force for air suction; A guide unit for guiding the flow of air sucked by the suction unit; A filter member provided at one side of the suction device, the filter member allowing foreign matter in the sucked air to be filtered; And a filter cleaning unit to which dust separated from the filter member is sucked, wherein the filter cleaning unit is provided at one side of the filter member and forms a flow path through which air flows; A plurality of suction portions provided in the flow path pipe to receive foreign matter adsorbed on the filter member and arranged to face each other; And a dust discharge unit for discharging the foreign substances introduced from the plurality of suction units and capable of connecting the vacuum cleaner.

In detail, the filter cleaning unit 100 includes a first flow path pipe 101 and a second flow path pipe 102, which form an intermediate flow path so that dust separated from the filter member 51 is discharged to the vacuum cleaner 80, A suction unit 103 provided on at least one side of the first flow path pipe 101 and through which the dust is sucked from the filter member 51 and a vacuum cleaner 80 connected to the flow pipe 101, And a dust discharging portion 104 for discharging the dust that has been moved through the vacuum cleaner 80.

More specifically, the flow path pipes 101 and 102 form an overall appearance of the filter cleaning part 100. The plurality of first flow path pipes 101 are arranged in a state of being spaced apart from each other in the transverse direction and the second flow path pipes 102 are arranged in the longitudinal direction, And communicates with one side.

However, the number and position of the flow pipes 101 and 102 are not limited to those shown in FIG. 3, and various embodiments may be proposed if the airflow is smooth.

The suction unit 103 is provided on the outer circumferential surface of the flow path pipes 101 and 102 and has a cylindrical shape with a smaller diameter than the flow path pipes 101 and 102. The suction unit 103 is connected to the upper and lower sides of the flow path pipes 101 and 102 and extends upward and downward, respectively. That is, as shown in FIG. 3, the plurality of suction units 103 may be disposed to face each other.

A suction hole 103a is formed at the side end of the suction unit 103 to allow air containing dust to flow therethrough.

 The suction hole 103a is positioned adjacent to one surface of the filter member 51 in a state where the filter cleaning unit 100 is mounted. In this case, the suction force by the vacuum cleaner 80 can be easily applied to the filter member 51.

As a result, the dust separated from the filter member 51 can be introduced into the suction unit 103 from above and below the suction unit 103.

Meanwhile, although the suction unit 103 is provided on the upper and lower sides of the flow pipes 101 and 102, the suction unit 103 may be provided on one side of the flow pipes 101 and 102. In this case, the suction unit 103 may be arranged to be in contact with one surface of the filter member 51 so that the dust accumulated in the filter member 51 can be sucked into the filter cleaning unit 100 more easily .

In addition, the dust discharging portion 104 is connected to one side of one pipe of the first flow path pipe 101. Dust moved through the first flow pipe 101 and the second flow pipe 102 may be discharged to the outside through the dust discharge unit 104.

The vacuum cleaner 80 may be connected to the dust outlet 104.

In general, a vacuum cleaner is provided with a suction motor, a dust separator for separating dust from the sucked air, a cleaner main body provided with a dust storage part for storing separated dust in the air, And a cleaner nozzle for sucking dust-containing air from the cleaning surface. Between the cleaner main body and the nozzle, a connecting means for moving the sucked air may be provided.

4, the vacuum cleaner 80 includes a nozzle connection part 81 connected to the cleaner nozzle and an extension pipe 82 extending from the nozzle connection part 81 to the cleaner main body 83 .

The nozzle connecting portion 81 may be connected to the dust discharging portion 104.

Hereinafter, the process of separating the dust from the filter member 51 of the air cleaner according to the first embodiment of the present invention and discharging it to the vacuum cleaner 80 will be briefly described.

First, the front case 20 is opened so that the inside of the main body 10 is opened, and then the filter assembly 50 is pulled out forward. Then, the nozzle connecting portion 81 of the vacuum cleaner 80 is connected to the dust discharging portion 104.

In this state, when the vacuum cleaner 80 is operated, a suction force is generated by a suction motor (not shown) of the vacuum cleaner 80, and the suction force is transmitted through the extension pipe 82 and the nozzle connection portion 81 And acts on the filter cleaning unit 100.

Since the suction force is applied to the suction unit 103 through the flow path pipes 101 and 102, the dust accumulated in the filter member 51 is separated from the filter member 51 and is discharged through the suction hole 103a And then flows into the suction portion 103.

The dust is moved to the dust discharging part 104 through the flow path pipes 101 and 102 and may be introduced into a dust collecting device (not shown) of the vacuum cleaner 80.

Since the suction unit 103 is arranged at a predetermined distance, suction force through the suction unit 103 can be applied to the filter member 51 over almost the entire range. As a result, the dust collected in the filter member 51 can be easily separated.

Hereinafter, an air purifier according to a second embodiment of the present invention will be described. The present embodiment differs from the first embodiment in the structure of the filter cleaning section. Therefore, differences will be mainly described, and the same description and reference numerals will be used for the same portions as in the first embodiment.

6 is a front view showing a filter cleaner of an air cleaner according to a second embodiment of the present invention.

6, the air purifier 1 according to the second embodiment of the present invention is provided with a plurality of filter members 51, and a suction force acts to separate dust collected in the filter member 51 And a filter cleaning unit 200 is provided.

In detail, the filter cleaning unit 200 includes a first flow path pipe 201 provided at a rectangular rim and providing a flow path for moving dust separated from the filter member 51, And a plurality of second flow path pipes 202 arranged in a diagonal direction.

The second flow path pipe 202 is provided with a suction portion 203 protruding from the filter member 51 so that suction force acts on the dust of the filter member 51. Dust is sucked into the end portion of the suction portion 203 And a suction hole 203a is formed through the through hole. Since the suction portion 203 is in communication with the second flow path pipe 202, the dust sucked through the suction portion 203 can be moved through the second flow path pipe 202.

The dust moving through the flow pipes 201 and 202 may be discharged to the filter cleaning unit 204 through the dust discharge unit 204.

Since the plurality of suction portions 203 are provided inside the first flow path pipe 201 at a predetermined distance apart from each other as in the first embodiment, Can be easily separated and removed.

Meanwhile, the process in which the dust collected in the filter member 51 is separated and sucked into the vacuum cleaner 80 is the same as that in the first embodiment, and therefore, description thereof is omitted here.
