Abstract

Some embodiments of the invention include a ventilation apparatus including a housing assembly with at least one fluid inlet, and at least one fluid outlet, and an exhaust fan assembly coupled to the housing assembly within an inner region. The exhaust fan assembly can include a scroll positioned within and coupled to the main housing, and a blower wheel positioned within the scroll and mechanically coupled to the motor. The ventilation assembly can include a configurable mounting panel including a main panel and at least one tab, and at least one configurable flange coupled to the main panel and extending outwardly from the main panel. The configurable mounting panel can include at least one bending region with at least one aperture. The ventilation apparatus can also include a muffler including an aperture, an electrical box enclosure including a lid, and a duct connector assembly each coupled with the housing assembly.

Claims

1. A ventilation apparatus, comprising:

a housing assembly including a main housing comprising a plurality of side walls including at least a first side wall coupled to a second side wall at an edge to at least partially enclosing an inner region, the housing assembly including at least one fluid inlet for receiving fluid from a surrounding environment, and at least one fluid outlet positioned through the first side wall of the main housing, wherein at least one of the side walls comprises a tab;

an exhaust fan assembly coupled to the housing assembly within the inner region, the exhaust fan assembly comprising a scroll positioned within and coupled to the main housing, and a blower wheel positioned within the scroll and mechanically coupled to a motor and capable of generating a fluid flow within the scroll;

a configurable mounting panel comprising;

a main panel configured to be positioned-against at least one of the plurality of side walls of the main housing such that the main panel is integral to the at least one of the plurality of side walls,

at least one configurable flange coupled to the main panel and extending outwardly from the main panel, and

at least one bending region coupled between the main panel and the at least one configurable flange, wherein the at least one bending region comprises at least one aperture and is positioned proximate the edge permitting deflection of the at least one configurable flange relative to the main panel around the edge.

2. The ventilation apparatus of claim 1, further comprising a muffler including a muffler aperture, the muffler positioned within and coupled to the housing assembly.

3. The ventilation apparatus of claim 2, wherein the muffler includes a top panel top side, a bottom side and an outer periphery region around the muffler aperture, the outer periphery region comprising a substantially convex surface on the top side and a substantially concave surface on the bottom side.

4. The ventilation apparatus of claim 2, wherein the muffler further includes a plurality of structural ridges coupled to the substantially concave surface in the bottom side.

5. The ventilation apparatus of claim 2, wherein the muffler further includes a plurality of fastening mounts, the plurality of fastening mounts configured and arranged to couple the muffler to the exhaust assembly and the main housing.

6. The ventilation apparatus of claim 1, wherein the configurable mounting panel is coupled to the second side wall.

7. The ventilation apparatus of claim 1, wherein the second side wall comprises the configurable mounting panel.

8. The ventilation apparatus of claim 1, wherein the configurable mounting panel includes at least one mounting aperture.

9. The ventilation apparatus of claim 1, wherein the configurable mounting panel includes a first configurable flange and a second configurable flange.

10. The ventilation apparatus of claim 9, wherein the first configurable flange and the second configurable flange each comprise at least one mounting aperture.

11. The ventilation apparatus of claim 10, wherein the first configurable flange and the second configurable flange each further comprise an aperture.

12. The ventilation apparatus of claim 1, further comprising at least one electrical box enclosure.

13. The ventilation apparatus of claim 12, wherein the at least one electrical box enclosure includes at least two anchoring flanges;

and

wherein the electrical box enclosure is secured to the housing assembly by a first anchoring flange coupling with a third side wall of the main housing, and a second anchoring flange coupling with a fourth side wall of the main housing.

14. The ventilation apparatus of claim 12, wherein the at least one electrical box enclosure includes an electrical box cover plate.

15. The ventilation apparatus of claim 14, wherein the electrical box cover plate is secured to the electrical box enclosure using at least one screw.

16. The ventilation apparatus of claim 15, wherein the electrical box cover plate further comprises a lifting tab.

17. The ventilation apparatus of claim 16, wherein the electrical box cover plate can be at least partially opened by pivoting the plate about an edge by applying a lifting force to the lifting tab following loosening and removal of the screw.

18. The ventilation apparatus of claim 1, further comprising a duct connector assembly coupled to the first side wall of the main housing.

19. A ventilation apparatus, comprising:

a housing assembly including at least one fluid inlet for receiving fluid from a surrounding environment and a main housing comprising at least a first side wall coupled to a second side wall at an edge, wherein the housing assembly comprises a configurable mounting panel, wherein at least one of the side walls comprises a tab;

a fluid outlet positioned through the first side wall of the main housing;

an exhaust fan assembly comprising a scroll positioned within and coupled to the main housing, and a blower wheel positioned within the scroll and mechanically coupled to a motor and capable of generating a fluid flow within the scroll and fluid discharge through the fluid outlet; and

a muffler including an aperture, the muffler positioned within and coupled to the housing assembly;

wherein the configurable mounting panel comprises;

a main panel configured to be positioned against the second side wall such that the main panel is integral to the at least one of the plurality of side walls,

at least one configurable flange coupled to and extending outwardly from the main panel, and

at least one bending region coupled between the main panel and the at least one configurable flange, wherein the at least one bending region comprises at least one aperture and is positioned proximate the edge permitting deflection of the at least one configurable flange relative to the main panel around the edge.

20. The ventilation apparatus of claim 19, further comprising an electrical box enclosure coupled within the main housing and a duct connector assembly coupled to the first side wall.
