Abstract
An airflow window includes an outer frame, an inner frame, and shutters. The outer frame defines a first opening and a plurality of guiding slots. The inner frame defines a second opening. The first opening communicates with the second opening. Each shutter includes an interfering tab. The shutters cooperatively block the first opening and the second opening in a closed state. A surface in each guiding slot retards a moving speed of the shutters on the interfering tab when the shutters rotate from an open state to the closed state.

An airflow window comprising:
- an outer frame defining a first opening and a plurality of guiding slots;
- an inner frame defining a second opening, and the first opening communicating with the second opening;
- a plurality of shutters, each of the plurality of shutters comprising an interfering tab, the plurality of shutters being adapted to cooperatively block the first opening and the second opening in a closed state;
- and
- wherein a surface in each of the plurality of guiding slots retards a moving speed of the plurality of shutters on the interfering tab when the plurality of shutters rotate from an open state to the closed state.
An airflow window comprising:
- an outer frame;
- an inner frame engaged with the outer frame;
- and
- a plurality of shutters being pivotably retained cooperatively by the inner frame and the outer frame,
- wherein each of the plurality of shutters is interfered with the outer frame to reduce a rotating speed of the plurality of shutters when each of the plurality of shutters rotates up or down.
An airflow window comprising:
- an outer frame, defining at least one guiding slots;
- an inner frame engaged with the outer frame;
- and
- a plurality of shutters being pivotably retained between the inner frame and the outer frame, and each of the plurality of shutter comprising an interfering tab,
- wherein each of the plurality of shutters is rotated from an open state, where the interfering tab is located at a bottom end of the at least one guiding slot, to a closed state, where the interfering tab is located at a top end of the at least one guiding slot.
