Patent ID: 7984859

Claim:
In combination with an air moving device, an apparatus for controlling at least one of a humidity and odor in an enclosed confine, said apparatus comprising: (a) a switch mounted within a path of electric power between an electric power source and said air moving device, said switch operable by a presence of a control signal to supply said electric power to said air moving device and is operable by an absence of said control signal to remove said electric power therefrom; (b) a humidity sensor mounted in a predetermined location and is operable to output a humidity signal defining level of relative humidity within said enclosed confine, said humidity signal being a voltage signal; (c) a resistive voltage divider for providing a reference voltage signal associated with a predetermined level of humidity; (d) means coupled to each of said humidity sensor and said resistive voltage divider for comparing said humidity signal with said reference signal and providing said control signal when a value of said humidity signal is equal to or greater than a value of said reference signal, said control signal causing said switch to supply said electric power to said air moving device; (e) a first timing circuit activatable by said control signal and is operable to maintain said presence thereof for a predetermined period of time when said value of said humidity signal decreases below said value of said reference signal; (f) means operable by a user for providing said control signal independently from said comparing means; (g) a second timing circuit coupled to said user operable means and operable thereby to maintain said control signal for a second predetermined period of time upon activation of said user operable means, whereby said switch is deactivated after expiration of said second predetermined period of time to remove said electric power from said air moving device; and (h) a third timing circuit activatable by said user operable means at a predetermined time delay after activation of said second timing circuit and is operable for a third predetermined period of time.
