If the detected intensity is greater than the standard intensity, it can be predicted that the current state is daytime or the lighting is turned on and the user is active.However, if the detected intensity is less than the standard intensity, the present state is night and the light is turned off. It can be predicted as

Accordingly, when the detected luminous intensity is greater than the reference luminous intensity, the controller 100 controls to output the forward current power (or reverse current power) to the power supply 114, and the power supply 114 controls the forward current power (or reverse current). Power supply) is applied to the exhaust / intake ventilator 27, 37.

The electromagnets 27c of the exhaust / intake doors 27 and 37 move the exhaust / intake doors 24 and 34 according to the left (or right) linear motion according to the forward current power source (or reverse current power source). Slid to the left (or right) to open.

The control unit 100 controls the exhaust / intake fan motors 22 and 32 to the general mode to control the exhaust fan 25 to the intake fan 35 at an appropriate rotational speed according to the degree of contamination. In operation S16, the timer 108 for limiting the driving time of the fan motors 22 and 32 is initialized.

On the other hand, if the detected luminous intensity is less than or equal to the reference luminance, the controller 100 controls the fan motors 22 and 32 to be driven in the low noise mode, and blocks the driving of the fan motors 22 and 32, or Control to run at low speed compared to normal mode.

In order to prevent noise, the fan motors 22 and 32 are preferably not driven. However, when the pollution degree is too high, the fan motors 22 and 32 are driven to the minimum, and the fan motor ( The timer 108 for limiting the driving time of the 22 and 32 is initialized (S18).

After the driving of the fan motors 22 and 32 is started, the controller 100 determines whether the driving time limit set for limiting the driving of the fan motors 22 and 32 is reached through the timer 108. Check (S20).

Here, the driving time limit may be a time set by the user to prevent overheating of the fan motors 22 and 32 when the user sets an appropriate time or when the user does not set a separate driving time.

When the driving time limit is reached, the control unit 100 stops driving by applying a driving stop signal to the driving fan motors 22 and 32 (S24).

The control unit 100 applies a control signal to output the reverse current power (or forward current power) to the power supply unit 114, the power supply 114 exhausts / intakes the forward current power (or reverse current power) according to the control signal It is applied to the door openers 27 and 37.

The electromagnet 27c of the exhaust / intake door switch 27 and 37 moves linearly to the left (or right) according to the reverse current power source (or forward current power source) of the power supply unit 114 to exhaust / intake door 24 ( 34) Close by sliding.

When the driving time limit is not reached, the controller 100 checks whether the pollution degree of the current indoor air detected by the pollution degree sensor unit 112 is reduced enough to meet the driving stop condition of the ventilator 10. In operation S22, when the driving stop condition of the ventilation device 10 is met, driving stop signals are applied to the fan motors 22 and 32 to stop driving (S24).

The control unit 100 applies a control signal to output the reverse current power (or forward current power) to the power supply unit 114, and the power supply unit 114 exhausts the reverse current power (or forward current power) according to the control signal. / Is applied to the intake door opener (27, 37).

The electromagnet 27c of the exhaust / intake door switch 27 and 37 slides the exhaust / intake doors 24 and 34 to the left (or right) according to the reverse current (or forward current) of the power supply 114. Close it.

As described above, the present invention can be forced to be ventilated by the rotation of the intake fan and the exhaust fan according to the pollution degree of the indoor air without being affected by the external environment, and at night the drive of the ventilation fan is blocked or controlled at low speed The driving noise is minimized.

Embodiments according to the present invention described above are not limited to those described above, it can be carried out in various modifications within the scope obvious to those skilled in the art with respect to the present invention.

As described above, according to the ventilator according to the present invention, the ventilation may be forced by the rotation of the intake fan and the exhaust fan without being affected by the external environment. By having an air flow structure installed to be adjacent to the external exhaust port and the internal intake port, ventilation can be easily achieved.

In addition, according to the present invention, carcinogens such as volatile organic compounds emitted from various building materials used in a new house, for example, benzene, toluene, chloroform, acetone, and formaldehyde and carbon monoxide, carbon dioxide, nitrogen oxide, And by detecting the pollutants such as ozone by the sensor and discharged to the outside can prevent headache, cough, itching, dizziness, fatigue caused by the so-called 'sick house syndrome'.
