Abstract
The invention provides a method and apparatus for controlling a ventilation device. When the power switch of a room is turned on, the light of the room is turned on and the fan of the room is also turned on. When the power switch is turned off the light goes off, the automatic controlled fan still works for a predetermined amount of time (say, 5 minutes) and then shuts off automatically. If later the room is not being used, the automatic controlled fan will automatically repeat turning on and off (only turned on for a short time say, 5 minutes) periodically according to a set interval (say, repeat every 30 minutes). By the above automatic control of the ventilation fan, the bad odors or humid air in the room can be removed. If the room is not used for a longer period of time (say, 12 hours), the automatic controller enters sleep mode and the sleep timer will shut off the automatic repeat on/off function. In sleep mode, the fan won't be automatically turned-on/off to save energy assuming that the humid air in the room is well ventilated. With the user-friendly and energy saving automatic control features over the ventilation fan, the user can enjoy a better living quality.
