I don't believe it does. The dryer is described as "ventless", and if it were drawing air in it would have to vent it out. From what I have been able to infer, the drying cycle is an extraction process, aided by some heat, but the water leaves the machine via the drain, not through venting.

This apparently is more efficient than an evaporative process from an energy consumption standpoint, but less efficient in terms of time.
