Air cleaner airflow shaper
View Patent ↗An airflow shaper for use in an air cleaner is provided according to an embodiment of the invention. The airflow shaper includes a body including a substantially central axis and a raised central region formed on the body. The raised central region transitions an impinging axial airflow into a substantially radial airflow or transitions an impinging radial airflow into a substantially axial airflow.
1. A tower air cleaner, comprising:
a base portion;
a tower portion extending substantially vertically above the base portion;
an air inlet extending at least partially around a first circumference of the tower portion;
an air outlet;
an air duct connecting the air inlet to the air outlet and including an inlet end and an outlet end; and
at least one airflow shaper with a substantially cylindrical raised central region positioned in the air duct, wherein the airflow shaper transitions airflow in the tower air cleaner between a substantially vertical airflow and an airflow at an angle less than vertical.
2. The tower air cleaner of claim 1 , with the air duct extending substantially vertically in the tower portion and with the air inlet being vertically spaced apart from the air outlet.
3. The tower air cleaner of claim 1 , with the at least one airflow shaper comprising an airflow shaper located at the outlet end of the air duct.
4. The tower air cleaner of claim 1 , with the at least one airflow shaper comprising an airflow shaper located at the inlet end of the air duct.
5. The tower air cleaner of claim 1 , with the at least one airflow shaper comprising a first airflow shaper located at the inlet end of the air duct and a second airflow shaper located at the outlet end of the air duct.
6. The tower air cleaner of claim 1 , with an airflow shaper of the at least one airflow shaper comprising:
a body including a substantially central axis; and
a raised central region formed on the body, wherein the raised central region transitions an impinging axial airflow into a substantially radial airflow or transitions an impinging radial airflow into a substantially axial airflow.
7. The airflow shaper of claim 6 , with the raised central region being substantially centered on the axis.
8. The airflow shaper of claim 6 , with the raised central region being substantially hollow and substantially cylindrical.
9. The airflow shaper of claim 6 , with the raised central region being substantially cylindrical and with the raised central region being adapted to substantially match an exterior profile of an air moving device.
10. The airflow shaper of claim 6 , with the airflow shaper further comprising a plurality of vent apertures.
11. The airflow shaper of claim 6 , with the airflow shaper further comprising an ionizer cut-out.
12. The airflow shaper of claim 6 , with the airflow shaper further comprising a wiring channel.
13. A tower air cleaner, comprising:
a base portion;
a tower portion extending substantially vertically above the base portion;
an air inlet extending at least partially around a first circumference of the tower portion;
an air outlet;
an air duct connecting the air inlet to the air outlet and including an inlet end and an outlet end; and
at least two airflow shapers positioned in the air duct, wherein the at least two airflow shapers transition airflow in the tower air cleaner between a substantially vertical airflow and an airflow at an angle less than vertical.
14. A tower air cleaner, comprising:
a base portion;
a tower portion extending substantially vertically above the base portion;
an air inlet extending at least partially around a first circumference of the tower portion;
an air outlet;
an air duct connecting the air inlet to the air outlet and including an inlet end and an outlet end; and
at least one airflow shaper positioned in the air duct, wherein the airflow shaper comprises projections and transitions airflow in the tower air cleaner between a substantially vertical airflow and an airflow at an angle less than vertical.
