4 is an operation diagram showing the operation of the ventilation means 100 for balcony ventilation.

Referring to Figure 4 looks at the operation sequence of the ventilation means 100 by the control panel 60 as follows.

When the indoor humidity of the balcony rises above the reference value set in the humidity sensor, the motor 43 rotates forward by detecting the humidity sensor 30 so that the direction change damper 40 connected to the motor 43 is removed from the bathroom suction port. Move in the (71) direction. The direction change damper 40 arriving at the bathroom suction port 71 comes into contact with the limit switch 41 provided at the bathroom suction port 71, and the limit switch 41 is connected to the limit switch 41 through a signal generated by the contact. The operation of the motor 43 is stopped. Thereafter, the exhaust fan 70 is operated to perform ventilation of the air inside the balcony.

When the relative humidity in the balcony falls below the set humidity through the above process, the operation of the exhaust fan 70 is stopped through the control of the control panel 60 according to the control signal of the humidity sensor 30. By repeating the above process it is possible to maintain the proper humidity of the balcony, thereby preventing the condensation of the balcony.

Balcony condensation is the main cause of the humidity inside the balcony above a certain level, but condensation occurs even at relatively low humidity when the temperature gradient between the inside and outside of the balcony is large. Therefore, it is difficult to effectively prevent condensation simply by exhausting the humid air inside the balcony to the outside. That is, it is more effective to prevent condensation by lowering the temperature gradient by sucking outside air into the balcony in addition to the exhaust of the air inside the balcony by the forced suction. In addition, if the interior space of the balcony is completely closed and only the air inside the balcony is exhausted in the absence of indoor and outdoor air flow, the exhaust capacity per unit time is reduced, thereby reducing the efficiency.

As described above, the outdoor air flowing into the natural air supply 90 is provided with a natural air supply 90 on one side of the balcony which is in contact with the outside, and the exhaust grill 50 and the exhaust fan 70 installed in the balcony. As it is discharged to the outside through), the air flow is induced to reduce the humidity in the room more efficiently, and it is possible to reduce the indoor and outdoor temperature gradient within a short time, thereby completely preventing the condensation of the balcony.
