Abstract

Systems and methods provide airflow to a first area from a second area within a vehicle. The system includes a fan mounted within a door separating the first area from the second area. The fan is configured to direct airflow from the second area into the first area. The fan having a shield positioned adjacent to the second area that is configured to conceal the fan.

First claim

What is claimed is:

1. A system for providing airflow in a vehicle, the system comprising:
a fan mounted within a door separating a first area from a second area, the fan being configured to direct airflow from the second area into the first area; and
a shield positioned adjacent to the fan and facing the second area, the shield configured to conceal the fan.

2. The system of claim 1 , wherein the airflow increases an air pressure within the first area.

3. The system of claim 2 , wherein the door includes a vent valve configured to reduce the air pressure within the first area.

4. The system of claim 1 , further comprising a filter situated between the shield and the fan within the door, the filter configured to remove particles from the airflow.

5. The system of claim 4 , wherein the filter is a high efficiency particulate air (HEPA) type filter.

6. The system of claim 1 , wherein the fan includes a light source configured to indicate at least one of operation of the fan, a status of a filter, or a condition within the first area.

7. The system of claim 1 , wherein the fan is operably coupled to an environmental control system (ECS), the fan being configured to activate based on instructions received from the ECS.

8. The system of claim 1 , wherein the first area includes a user interface, the fan being configured to activate based on instructions received from the user interface.

9. The system of claim 1 , further comprising a second fan mounted within the door configured to direct airflow from the second area into the first area, wherein the shield is configured to conceal both the first fan and the second fan.

10. The system of claim 1 , further comprising an elastomeric mount configured to dampen sound emitted by the fan.

11. The system of claim 1 , wherein the shield is a metal or ceramic plate configured to absorb an impact or stop penetration of an external projectile into the fan.

12. A method for providing airflow in a vehicle, the method comprising:
mounting a fan within a door that separates a first area from a second area, wherein the fan is coupled to a shield positioned adjacent to the second area, and wherein the fan is configured to direct an airflow from the second area into the first area.

13. The method of claim 12 , wherein the directing operation includes adjusting an air pressure within the first area.

14. The method of claim 13 , further comprising releasing air pressure from the first area via a vent valve positioned on the door.

15. The method of claim 12 , further comprising filtering the airflow from the second area by removing particles from the airflow into the first area.

16. The method of claim 12 , further comprising activating a light source that indicates at least one of operation of the fan, a status of a filter, or a condition within the first area.

17. The method of claim 12 , further comprising activating the fan based on instructions received from an environmental control system or a user interface.

18. The method of claim 12 , further comprising activating a second fan mounted within the door to direct airflow from the second area into the first area, wherein the shield is configured to conceal the second fan.

19. The method of claim 12 , further comprising dampening sound emitted by the fan by an elastomeric mount.

20. A method for providing airflow in a vehicle, the method comprising:
causing a fan to direct airflow from a second area to a first area, wherein the fan is within a door that separates the first area from the second area, and wherein the fan is coupled to a shield positioned adjacent to the second area.
