The controller 13 is located on the upper part of the outdoor air radiator 1 and controls the rotational speed of the driving motor 11 in response to signals from the oxygen / carbon dioxide concentration measuring sensor 31 and the dust sensor 24 do. When it is determined through the oxygen / carbon dioxide concentration sensor 31 that the oxygen concentration has decreased to require air delivery, the drive motor 11 rotates in the forward direction to send outdoor air to the room, and the dust sensor 24, When it is determined that more dust than the reference value is accumulated in the pipeline 2, the drive motor 11 rotates in the reverse direction to perform the pipeline cleaning procedure.

As shown in FIG. 1 and the like, the indoor air purifier 3 is installed in the room and discharges the air introduced through the pipeline outdoors. The indoor air purifier 3 includes an interchangeable tertiary filter 32 so that the contaminants filtered by the primary filter 14 and the duct cleaning device 23 pass through the tertiary filter 32, So that the clean air is discharged through the clean air discharge port 33.

Further, the indoor air purifier 3 attaches an oxygen / carbon dioxide concentration sensor 31 to measure the concentration of oxygen and carbon dioxide in the room, collects information and sends information to the controller 13, (13) controls the delivery amount of air. When the concentration of carbon dioxide in the room is increased and the oxygen concentration is decreased, the oxygen concentration in the room can be maintained and a pleasant environment can be created by supplying clean air.

The duct 2 connects the outdoor air and the room to the room, and connects the outdoor air dispenser 1 to the indoor air purifier 3. [ The pipeline 2 is connected to an outside air delivery pipe 21 located outside the room and an air inlet pipe 22 located inside the room. In addition, the pipeline 2 includes a channel cleaning device 23 and a dust sensor 24.

The dust removing unit 232 is made of a vinyl material and is formed in the form of a fine pine tree of pine trees, and functions as a filter to remove dust secondarily when outside air is introduced.

A dust sensor 24 is installed inside the pipeline 2. The dust sensor 24 measures the degree of accumulation of dust in the pipeline and sends the collected information to the controller 13 when dust having a predetermined standard value or more is accumulated . The controller 13 can determine the degree of contamination with the collected information and execute the channel cleaning procedure.

In the conduit cleaning procedure, the conduit cleaning device 23 rotates in association with the driving motor 11, and the dust removing part 232 having a vinyl-like leaf shape due to the centrifugal force generated when the conduit cleaning device 23 is rotated, And the dust adhered to the inner wall can be removed, and the contaminants adsorbed on the leaves can also be removed.

The outdoor air discharger 1 includes a coupling unit 15 connecting the fan 12 and the duct cleaning apparatus 23 and the coupling unit 15 is connected to the duct cleaning apparatus 23 So that the pipeline can be cleaned.

3 and the like, the coupling portion 15 includes a protrusion 151 and a seating portion 152. The protrusion 151 protrudes from the driving motor 11 in the direction of the channel cleaning device 23, And the seating part 152 is formed on one side of the rotating shaft 231 of the channel cleaning device 23 in the direction of the drive shaft 111. The controller 13 is provided on one side of the driving shaft 111, It is possible to fasten or disassemble the protruding portion 151 and the seating portion 152 of the binding portion 15 under the control of the user.

If it is determined that the supply of clean air to the room is necessary due to the information collected by the oxygen / carbon dioxide concentration sensor 31, the coupling unit 15 may be configured such that the driving motor 11 rotates in the forward direction, And the pressure is applied to the outside in the room according to the moving direction of the air. At this time, the fan 12 is influenced by the moving direction of the air, and the fan 12 and the driving shaft 111 are moved in the direction of the motor so that the binding unit 15 is disassembled. When the degree of contamination is judged to be higher than the reference value by the information collected by the dust sensor 24, the driving motor 111 rotates in the reverse direction to move the air from the room to the outside, In the indoor direction. The fan 12 and the drive shaft 111 are moved in the direction of the channel cleaning device 23 and the rotation of the drive shaft 111 and the channel cleaning device 23 (231) are coupled with each other so that the coupling portion (15) is engaged.

When the purified air is supplied to the room, the fan 12 moves in the direction of the driving motor 11 to move the binding unit 15 in the direction of the driving motor 11, The fan 12 is moved in the direction of the coupling part 15 and the driving shaft of the coupling part 15 is rotated 111 and the rotary shaft 231 of the duct cleaning apparatus 23 are coupled to each other so that the drive motor 11 rotates in reverse while rotating the rotary shaft 231 of the duct cleaning apparatus 23 Switch. The binding portion 15 can turn ON / OFF the binding portion 15 with a change in pressure without an additional device to be controlled.

The bundling unit 15 connects the channel cleaning device 23 and the fan 12 so that the channel can be cleaned by one driving motor 11. Therefore, when a pipeline cleaning procedure is performed, a driving motor for rotating the pipeline cleaning device 23 is not required separately, so that power consumption can be prevented.

Further, the indoor air purifier 3 is provided with a valve opening / closing device 34, which can be closed or opened according to the flow of air. When the clean air is supplied to the room, when the air moves from the outside to the room due to the forward rotation of the driving motor 11, the valve-closing device 34 is closed, and when the pipe cleaning procedure is performed, The valve-opening / closing device 34 is opened when the air moves from the room to the outside. The valve opening / closing device 34 is opened in accordance with the reverse rotation of the drive motor 11 at the time of cleaning the duct, so that clean indoor air flows into the duct 2, and the introduced clean air passes through the duct cleaning device 23 It is possible to clean the pipeline by moving to the outside while shaking off the dust and dust in the pipeline 2.

According to the embodiment of FIG. 1, in the case of the indoor clean air supply system according to the present invention, the dust sensor 24 attached to the pipeline 2 senses dust accumulated in the pipeline, Send the collected information. The controller (13) judges the degree of contamination by the information collected by the dust sensor (24), and performs a channel cleaning procedure. The pipeline cleaning procedure is performed by tightening the protruding portion 151 of the binding portion 15 and the seating portion 152 and reversing the drive motor 11 to switch the flow of air from the room to the outside, . A dust removing unit 232 in the form of a pine pine needle made of vinyl material rubs against the outer wall of the duct to generate dust that is attached to the inner wall of the duct cleaning unit 23 by the centrifugal force generated when the duct cleaning apparatus 23 fastened by the binding unit 15 rotates It also shakes off pollutants adsorbed on the leaves. The pressure of the pipeline is reduced according to the air flow flowing from the room to the outside, and the valve opening / closing device 34 is opened, so that the clean air in the room flows into the pipeline, cleaning the pipeline with clean air to clean the pipeline When air is delivered to the room, more clean air is supplied to maintain the oxygen concentration in the room and to create a pleasant environment.

That is, in the case of the conventional indoor air cleaner, the polluted air flowing into the room from outside the room can not be prevented by filtering pollutants from the air entering the room. Or when there is no cleaning device in the apparatus when the air is blown out from the outside to the room, the air is blown out with the dust or contaminants piled up in the apparatus, and it is difficult to supply completely clean air. However, the indoor clean air supply system according to the present invention essentially blocks indoor air inflow of outdoor air, and is installed in the duct 2 without separating the apparatus through the dust sensor 24 and the duct cleaning device 23 Dust and dust can be removed.

1, in the indoor clean air supply system according to the present invention, the oxygen / carbon dioxide concentration sensor 31 measures the oxygen concentration of the indoor air, collects information, and transmits information to the controller The amount of air to be delivered is controlled. If the oxygen concentration decline in the room is measured, the air output from the room to the outside is increased. When the clean function is operated, the drive motor 11 rotates in the forward direction and the binding portion 15 is released according to the movement of air and the moving direction of the fan, and the valve-closing device 34 is in a closed state. After the pollutants are filtered through the primary filter 14, the outside air is introduced into the outdoor air discharger 1, and the outdoor air is sent to the duct 2 at a constant pressure using the fan 12. The outside air sent to the pipeline passes through the channel cleaning device 23, and the dust removing unit 232 adsorbs the pollutant to thereby secondarily remove the pollutant. The outside air passing through the duct 2 flows into the indoor air purifier 3, and after the pollutant is finally filtered by the tertiary filter, the clean air is discharged through the clean air outlet 33.

Therefore, the indoor clean air supply system according to the present invention is capable of cleaning the dust primarily through the primary filter 14 of the outdoor air discharger 1, and the filter function of the duct cleaning device 23, Dust can be filtered through the third filter 22 of the room air purifier 3 to clean air in the room and the third filter in the room can be replaced, If dust accumulates, clean air can be supplied by replacing the filter.

Therefore, clean air can be supplied even in an environment where windows are difficult to open due to external noise (factory noise, traffic noise, artificial noise, natural noise, etc.).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be interpreted as belonging to the scope.
