Airflow window
View Patent ↗An airflow window includes an outer frame, an inner frame located in the outer frame, a plurality of shutters, and a magnet. The plurality of shutters is pivotably mounted on the inner frame. Each shutter includes metal. The magnet includes at least one magnet strip. The at least one magnet strip attracts the plurality of shutters at an open state. In the open state, the plurality of shutters is slanted relative to the outer frame.
1. An airflow window comprising:
an outer frame defining a first opening, the outer frame comprising two sidewalls;
an inner frame defining a second opening, the inner frame located in the outer frame, and the first opening communicating with the second opening;
a plurality of shutters, each of the plurality of shutters, being pivotably mounted on the inner frame, each of the plurality of shutters comprising metal, each of the plurality of shutters located in a shutter plane, said plane is substantially perpendicular to each of the sidewalls, and the plurality of shutters being adapted to cooperatively block the first opening and the second opening when said shutters are in a closed state; and
a magnet comprising a magnetic strip, and the magnetic strip is located on one of the sidewalls of the outer frame to attract the plurality of shutters on a substantially lateral side of the plurality of shutters to reduce a rotating speed of the plurality of shutters when the plurality of shutters rotates from an open state to the closed state.
2. The airflow window of claim 1 , wherein each of the plurality of shutters comprises a pivot portion, and each of the plurality of pivot portions extends along a first direction that is substantially perpendicular to the two sidewalls.
3. The airflow window of claim 2 , wherein the magnetic strip is located in a magnetic plane, that is substantially perpendicular to the first direction.
4. The airflow window of claim 1 , wherein the inner frame comprises a plurality of resilient hooks, and the outer frame comprises a plurality of locking holes corresponding to the plurality of resilient hooks.
5. The airflow window of claim 1 , wherein a plurality of blocks is located on the outer frame for preventing any excessive opening of the plurality of shutters, and the magnetic strip abuts the plurality of blocks.
6. The airflow window of claim 1 , wherein the plurality of shutters comprises iron, and the magnetic strip is a permanent magnet.
7. An airflow window comprising:
an outer frame;
an inner frame located in the outer frame;
a plurality of shutters being pivotably mounted on the inner frame, each of the plurality of shutters comprising metal; and
a magnet comprising at least one magnetic strip, and the at least one magnetic strip adapted to attract the plurality of shutters towards a partially open state, where the plurality of shutters is slanted relative to the outer frame.
8. The airflow window of claim 7 , wherein the outer frame comprises two substantially parallel sidewalls, the at least one magnetic strip is attached to the at least one of the two substantially parallel sidewalls; the each of the plurality of shutters comprises a pivot portion, and each pivot portion extends along a first direction that is substantially perpendicular to the two substantially parallel sidewalls.
9. The airflow window of claim 8 , wherein the at least one magnetic strip is located in a magnetic plane, that is substantially perpendicular to the first direction.
10. The airflow window of claim 7 , wherein the inner frame comprises a plurality of resilient hooks, and the outer frame comprises a plurality of locking holes corresponding to the plurality of resilient hooks.
11. The airflow window of claim 7 , wherein a plurality of blocks is located on the outer frame for preventing excessive open of the plurality of shutters, and the at least one magnetic strip abuts the plurality of blocks.
12. The airflow window of claim 7 , wherein the plurality of shutters comprises iron, and the at least one magnetic strips is a permanent magnet.
