のであった。With the above configuration, when the inside of the bathroom 101 becomes high humidity after taking a bath, the dew condensation sensor 1 connected to the ventilation fan control device 106
05 detects dew condensation, the ventilation fan control device 106 operates to operate the ventilation fan 103 and exhaust the high humidity air in the bathroom 101 to the outside 107. After taking a bath, if the air in the bathroom 101 becomes low humidity due to the operation of the ventilation fan 103 and reaches a normal humidity state where the dew condensation sensor 105 no longer detects dew, the ventilation fan control bag f\il 06 will operate again. , the ventilation fan 103 is delayed for a certain period of time and then stopped. In this way, it is possible to automatically prevent the inside of the bathroom 101 from always being in a high humidity state, suppress the growth of mold, etc., and prevent the bathroom 101 from rotting.
発明が解決しようとする課題
しかし、このような従来の構成では、入浴中でも入浴後
であっても、換気扇は一定量の排気を行うため、冬期に
おいては入浴中に寒さを感じさせ、また、入浴者に寒さ

して一定時間運転し、そののち換気扇３を停止させる。When the user takes a bath in the bathroom 1, the humidity in the bathroom 1 begins to rise (point S). When the humidity rises to a certain level (determined by the temperature and humidity of the outside air, the temperature of the bathroom wall, the material of the bathroom wall, etc.), condensation occurs on the inner wall of the bathroom 1 (point a). At this point, dew condensation also occurs in the dew condensation sensor 5 , the dew condensation sensor detects that the wall surface of the bathroom 1 is in a condensed state, and outputs this detection result to the ventilation fan control device 6 . The ventilation fan il control device 6 receives this output, determines to energize the low tap of the motor 8 of the ventilation fan 3, and causes the ventilation fan 3 to operate in low mode. Then, when you finish bathing (point E), continue this gentle operation,
As the humidity inside the bathroom 1 decreases, and when it drops to near the initial humidity state, the condensation on the wall of the bathroom 1 begins to disappear (point b. This is also determined by the same environment and other conditions as point a). At this point b, the condensation on the condensation sensor 5 also disappears, and the condensation sensor 5
determines that the wall surface of the bathroom 1 is dry, and stops outputting the detection signal to the ventilation fan control device 6. Upon this stop, the ventilation fan control device 6 determines to operate the ventilation fan 3 at full strength, operates for a certain period of time, and then stops the ventilation fan 3.

Ｆ状態とし、一連の換気動作が終了する。- During boat fishing, the drying speed of the inner wall of the bathroom 1 varies depending on the location, and the ceiling surface of the bathroom 1 where the dew condensation sensor 5 is installed
Since the drying time is considered to be different between the drying area and other parts, a certain delay time (1) is experimentally determined, and the ventilation fan 3 is operated in a delayed manner from point B to point C. This is the setting for the ventilation fan control device 6. At this point C, the ventilation fan control device 6 determines to stop energizing the motor 8 of the ventilation fan 3, stops the energization, and turns the ventilation fan 3 off.
The state is set to F, and a series of ventilation operations are completed.
