The ventilator cleaner 100 may further include a wireless communication unit (not shown) for receiving a measurement signal from a separate sensor, and the wireless communication unit may be implemented by a wireless communication technology such as Bluetooth, Wi-Fi, or 3G .

In addition, the ventilation cleaner 100 may receive an air condition related signal from outside (for example, a weather information provider or a vendor such as a weather station) through the wireless communication unit described above.

Meanwhile, the ventilation cleaner 100 according to an embodiment of the present invention can sense the dust or outdoor dust in the room through the indoor sensor unit 51 and the outdoor sensor unit 52, A control unit (not shown) may be configured to control the operation of the ventilation cleaner 100. For example, when the amount of dust in the room is higher than the set amount, the ventilator cleaner 100 is automatically operated, or when the amount of dust outside the room is higher than the set amount, the ventilator cleaner 100 is automatically operated, And can inform the user through the display unit (not shown) in a tone mode such as sound or flicker.

Accordingly, the inner door 23 and the outer door 24 can be interlocked and opened and closed. The pinion 26 may be connected to a driving motor, that is, a rotating motor, to receive a rotational force.

In other words, the inner door 23 and the outer door 24 are arranged so as to move the pinion 26 in the direction of the inner door 23 to the maximum extent to open the inner door 23 only, And the third door is opened at the third stage that simultaneously opens the inner door 23 and the outer door 24 by moving the second door 24 and the pinion 26 to the neutral position, Can be manipulated.

The ventilation cleaner 100 may further include a controller (not shown) for controlling the opening and closing of the inner door 23 and the outer door 24.

The control unit can control opening and closing of the inner door 23 and the outer door 24 by controlling the operation of the rack. More specifically, the opening and closing of the inner door 23 and the outer door 24 can be controlled by the first to third stages described above.

Can control the opening and closing of the inner door 23 and the outer door 24 according to the amount of dust detected by the indoor sensor unit 51 and the sensor unit 52. [

For example, when the amount of dust detected by the indoor sensor unit 52 is greater than the set amount, the control unit can automatically control the indoor air in the first stage because it is required to clean the indoor air. When the amount of dust detected by the outdoor sensor unit 52 is greater than the set amount, the control unit controls the second stage or the third stage to prevent the outdoor air from entering the room, Or to stop the operation.

Further, the housing 10 is provided with a carbon dioxide sensor 53 for sensing the carbon dioxide contained in the air sucked in the inner suction port 12, and the control unit controls the inside of the housing 10 according to the concentration of carbon dioxide detected by the carbon dioxide sensor 53 The opening and closing of the door 23 and the outer door 24 can be controlled.

For example, when the concentration of the carbon dioxide detected by the carbon dioxide sensor 53 is greater than a predetermined amount, the control unit may automatically detect that the outdoor air is being controlled to the first stage so as to be introduced into the room, Can be controlled to be changed. In addition, if it is not in operation, it can be controlled to start operation in the second-stage or third-stage manner.

In addition, the control unit can control the operation of the ventilation cleaner 100 based on a signal received from a sensor or a weather information provider through a wireless communication unit (not shown) as described above.

For example, when the concentration of carbon dioxide in the indoor air exceeds a predetermined reference value, or when the oxygen concentration is lower than a predetermined reference value, or when the indoor radon concentration is equal to or higher than a predetermined reference value, the control unit cleans the outdoor air, (23) and the outer door (24). In this case, it is possible to prevent sudden changes in the indoor air temperature by controlling the degree of opening of the inner door 23 and the outer door 24 by further considering the temperature difference between the indoor air and the outdoor air.

If the amount of dust in the indoor air or the amount of dust in the outdoor air exceeds a predetermined reference value, the control unit can control the inner door 23 and the outer door 24 at the first end so as to purify and discharge only indoor air .

In addition, the control unit can control the inner door 23 and the outer door 24 so that the indoor air can maintain a proper humidity based on the humidity of the indoor air and the outdoor air and the temperature of the indoor air.

For example, if the indoor air temperature is 30 ° C, the humidity is 80%, the outdoor air temperature is 27 ° C, and the humidity is 60%, open the outer door 24 so that relatively dry outdoor air flows into the room So that the humidity of the room air can be lowered.

The controller may be implemented by a processor such as a central processing unit (CPU), a graphics processing unit (GPU), a microprocessor, an application specific integrated circuit (ASIC), or a field programmable gate array .

The inner filter 41 and the outer filter 43 are a combination of a plurality of filtering means for filtering out foreign matter or dust in the air to provide clean air. To this end, the inner filter 41 and the outer filter 43 may have filters combined with at least two of a pre-filter, a pre-filter, a functional filter, a hepar filter, and a deodorizing filter.

That is, the inner filter 41 and the outer filter 43 are installed in the housing 10 to purify the incoming air.

The both suction fans 30 are disposed approximately in the central portion of the inner space 11. [ More specifically, the both suction fans 30 are disposed between the inner filter 41 and the outer filter 43 to suck air from both the inner suction port 12 and the outer suction port 13, . That is, the both suction fans 30 introduce the indoor or outdoor air into the inner space 11 of the housing 10, clean the filtered air while passing the filtered air through the filter, and discharge the air into the indoor space.

In this embodiment, both suction fans 30 may be bidirectional suction fans such as sirocco fans.

(Not shown) is disposed on at least one of the flow path between the both suction fans 30 and the inner suction port 12 and the flow path between the both suction fans 30 and the outer suction port 13, The function can be performed by the user.

In addition, in order to perform the humidifying function of the humidifier, any of humidification using the ultrasonic wave method and heating humidification using the temperature raised may be adopted.

The humidifier may perform a dehumidifying or humidifying function for the purified air passing through the inner filter 41 and the outer filter 43 under the control of the controller.

On the other hand, the display unit displays the state of indoor and outdoor air (for example, the concentration of carbon dioxide, the concentration of radon, the degree of contamination depending on the amount of dust, the temperature of the room, and the like) measured by the indoor sensor unit 51, the outdoor sensor unit 52 and the carbon dioxide sensor 53 And relative humidity) can be displayed.

The display unit is also provided with a predetermined behavioral guidance based on the indoor and outdoor air conditions measured by the indoor sensor unit 51, the outdoor sensor unit 52 and the carbon dioxide sensor 53 (for example, , Mask preparation, etc.).
