Abstract

Embodiments of the invention provide a lighting and ventilating system including a main housing. The main housing can include an inlet through which air can be received within the main housing and an outlet through which the air can exit the main housing. A fan wheel can be supported in the main housing and it can be operable to generate a flow of air. A grille can be coupled to the main housing and the grille can comprise at least one aperture. The system can include a plate coupled to the grille and the plate can include a recess. Also, a set of illumination devices can be at least partially disposed within the recess.

Claims

1. A ventilating system comprising:

a main housing defining an inlet configured to receive air into the main housing and an outlet configured to allow the air to exit the main housing;

a fan in the main housing and configured and arranged to generate a flow of air into the main housing through the inlet and from the main housing through the outlet;

a grille configured to be coupled to the main housing and defining at least one aperture; and

a plate coupled to the grille and defining an airflow path into the main housing between the plate and the grille.

2. The ventilation system of claim 1 wherein the plate defines a generally annular shape.

3. The ventilation system of claim 1 wherein the plate is larger than the grille.

4. The ventilation system of claim 1 wherein the plate is larger than the grille such that it extends laterally beyond the at least one grille aperture.

5. The ventilation system of claim 1 wherein the plate is smaller than the grille.

6. The ventilation system of claim 1 wherein the surface of the plate is at least partially textured.

7. The ventilation system of claim 1 wherein the plate comprises multiple plate units.

8. The ventilation system of claim 1 wherein the plate defines a plate aperture located substantially centrally on the plate.

9. The ventilation system of claim 1 wherein the plate defines a plate aperture located substantially centrally on the plate formed by a plate aperture wall and the plate aperture wall having a generally textured surface.

10. The ventilation system of claim 1 wherein the plate defines a plate aperture located substantially centrally on the plate formed by a plate aperture wall and the plate aperture wall including mounting notches.

11. The ventilation system of claim 1 wherein the grill defines a substantially curved area which engages the plate.

12. The ventilation system of claim 1 wherein the plate and the grille define an intake gap and air first passes through the intake gap before passing through the at least one grille aperture.

13. A ventilating system configured for ventilating a space comprising:

a main housing defining an inlet configured to receive air from the space into the main housing and an outlet configured to allow the air exit the main housing;

a fan supported in the main housing and configured and arranged to generate a flow of air from the space into the main housing through the inlet and from the main housing through the outlet;

a grille configured to be coupled to the main housing, the grille defining at least one aperture; and

a plate engaged with the grille defining an intake gap, such that air must first pass through the intake gap before passing through the at least one grille aperture.

14. The ventilation system of claim 13 wherein the plate defines a generally annular shape.

15. The ventilation system of claim 13 wherein the plate is larger than the grille.

16. The ventilation system of claim 13 wherein the plate is larger than the grille such that it extends laterally beyond the at least one grille aperture.

17. The ventilation system of claim 13 wherein the plate is smaller than the grille.

18. The ventilation system of claim 13 wherein the surface of the plate is at least partially textured.

19. The ventilation system of claim 13 wherein the plate comprises multiple plate units.

20. The ventilation system of claim 13 wherein the plate defines a plate aperture located substantially centrally on the plate.

21. The ventilation system of claim 13 wherein the plate defines a plate aperture located substantially centrally on the plate formed by a plate aperture wall and the plate aperture wall having a generally textured surface.

22. The ventilation system of claim 13 wherein the plate defines a plate aperture located substantially centrally on the plate formed by a plate aperture wall and the plate aperture wall including mounting notches.

23. The ventilation system of claim 13 wherein the grill defines a substantially curved area which engages the plate.

24. A ventilating system configured for ventilating a space comprising:

a main housing defining an inlet configured to receive air from the space into the main housing and an outlet configured to allow the air exit the main housing;

a fan supported in the main housing and configured and arranged to generate a flow of air from the space into the main housing through the inlet and from the main housing through the outlet;

a grille configured to be coupled to the main housing, the grille comprising a support frame and the grille defining at least one aperture; and

a plate engaged with the support frame.

25. A ventilating system comprising:

a main housing defining an inlet configured to receive air into the main housing and an outlet configured to allow the air to exit the main housing;

a fan in the main housing and configured and arranged to generate a flow of air into the main housing through the inlet and from the main housing through the outlet;

a grille configured to be coupled to the main housing and defining at least one aperture;

a plate coupled to the grille and defining a recess substantially adjacent an outer perimeter of the plate; and

a set of illumination devices disposed in the recess so that their illumination is directed inward and diffuses through the plate.

26. The ventilation system of claim 25 wherein the set of illumination devices is coupled to the plate.

27. The ventilation system of claim 25 wherein an interior surface of the recess is textured.

28. The ventilation system of claim 25 wherein the set of illumination devices is positioned so that their illumination generally illuminate the plate.

29. The ventilation system of claim 25 further comprising a panel coupled to the plate and surrounding an outer perimeter of the plate.

30. The ventilation system of claim 25 further comprising a panel having a panel flange engaging a recess defined in the plate.

31. The ventilation system of claim 25 wherein the grille comprises a support frame and at least one support flange coupled to the plate.

32. The ventilation system of claim 25 wherein the set of illumination devices comprises LEDs.

33. A ventilating system comprising:

a main housing defining an inlet configured to receive air into the main housing and an outlet configured to allow the air to exit the main housing;

a fan in the main housing and configured and arranged to generate a flow of air into the main housing through the inlet and from the main housing through the outlet;

a grille configured to be coupled to the main housing and defining at least one aperture;

a plate coupled to the grille; and

a set of illumination devices disposed substantially adjacent an outer perimeter of the plate so that their illumination is directed inward to generally illuminate the plate.
