Abstract
A system for controlling air quality in a vehicle cabin includes at least one mechanical filtering device receiving unfiltered air and collecting particulate matter from the unfiltered air. Air flow downstream from the mechanical filtering device is a first filtered air flow. At least one ultraviolet (UV) light source is positioned within the vehicle between the at least one mechanical filtering device and the vehicle cabin, wherein the UV light source directs UV light into the first filtered air flow.
Claims12
A system for controlling air quality in a vehicle cabin, the system comprising:
- at least one mechanical filtering device receiving unfiltered air from outside the vehicle cabin into an outside air inlet conduit and collecting particulate matter from the unfiltered air to create a first filtered air flow;
- a recirculation flap positioned in the outside air inlet conduit receiving the first filtered air flow, said recirculation flap being movable to allow and disallow the first filtered air flow into a blower feed conduit directing air flow into the vehicle cabin;
- an ultraviolet (UV) light source positioned within the blower feed conduit between the at least one mechanical filtering device and the vehicle cabin, wherein the UV light source directs UV light into the air flow within the blower feed conduit regardless of a position of the recirculation flap allowing or disallowing the first filtered air flow.
A system for controlling air quality in a vehicle cabin, the system comprising:
- at least one mechanical filtering device receiving unfiltered air from outside the vehicle cabin into an outside air inlet conduit and collecting particulate matter from the unfiltered air to create a first filtered air flow;
- a recirculation flap positioned in the outside air inlet conduit receiving the first filtered air flow, said recirculation flap being movable to allow and disallow the first filtered air flow into a second conduit;
- an ultraviolet (UV) light source positioned within the outside air inlet conduit, wherein the UV light source directs UV light into the first filtered air flow;
- and
- an additional UV light source positioned in the second conduit, wherein the additional UV light source directs UV light into a cabin air flow during a recirculation mode in which the recirculation flap is positioned to disallow the first filtered air flow into the second conduit.

- an ultraviolet (UV) light source positioned within the outside air inlet conduit, wherein the UV light source directs UV light into the first filtered air flow;
- and
- an additional UV light source positioned on an opposite side of the recirculation flap in another conduit;
- wherein the additional UV light source directs UV light into a cabin air flow during a recirculation mode in which the recirculation flap is positioned to disallow the first filtered air flow into the another conduit connected to the outside air inlet conduit.
