Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The clean air generator according to the present invention performs primary filtering through the outside air filter unit 100 in the process of introducing outdoor air into the inflow pipe 110 by the air blower 120, The next outdoor air is subjected to secondary filtering by a process in which fine bubbles generated by an air stone 230 installed so as to be submerged in the water tank 200 are in contact with and passed through the water, After filtering, clean air containing oxygen outside the room is supplied to the room through the discharge port 215 together with natural humidification.

The outside air filter unit 100 is installed at a wall surface entrance through which outdoor air can be introduced into a room from a high position on the upper side of a building to perform a filtering function. The outside air filter unit 100 is a nonwoven fabric, A filter made of a filter such as a filter for filtering dust larger than a hole in the process of passing air, and an activated carbon filter for adsorbing the odor contained in the air using activated carbon.

An air knife 130 having a plurality of air nozzles 132 formed therein is provided in the outside air filter unit 100 so that compressed air can be injected in the outside air direction by the compressor 150, The air filtering unit 100 is installed on the inner side of the outside air filter unit 100 so as to slide up and down or to the left and right by an operation member 140 such as a cylinder to perform a filter cleaning function to remove foreign substances adhered to the outside air filter unit 100.

The air knife 130 installed on the inner surface of the outside air filter unit 100 is connected to the outside air filter unit 100 through the outside air filter unit 100 through the air blower 120, In order to prevent the filtering operation, the air filtering unit 100 is provided at an eccentric position on the inner side, the lower side, the left side, or the right side of the outside air filter unit 100, 140, the compressed air is sprayed in the outside direction by the compressor 150 to perform filter cleaning.

 The filter cleaning of the outside air filter unit 100 by the air knife 130 is performed by operating the air knife 130 so as to stop the operation of the air blower 120 and prevent the inflow of air into the inflow pipe 110, The air blower 120 may be operated to operate the air knife 130 to perform the filter cleaning even in the process of air inflow into the inflow pipe 110. [

The reason why the filter of the outside air filter unit 100 can be cleaned in the process of operating the air blower 120 and introducing the outside air into the inflow pipe 110 is that the air is blown by the air blower 120 into the inflow pipe 110, The pressure of the compressed air injected from the air knife 130 to the outside air by the compressor 150 is much larger than the air pressure flowing into the air knife 130. Therefore, even if the operation of the air blower 120 is not interrupted, .

The filter cleaning of the outside air filter unit 100 by the air knife 130 may be performed by setting a time at which the filter function may deteriorate by setting a filter cleaning time or the like in advance with a timer or the like, It is preferable that the air knife 130 and the compressor 150 are operated by a vacuum cleaner (not shown) to perform filter cleaning.
