Abstract

Apparatus, systems and methods of 110 (one hundred ten) CFM (cubic feet per minute) generating ventilation fans for bathrooms with grill covers and with or without lights in the grill covers. Spring clip type washers can attach the grill covers to the housings. Suspension brackets directly attached to outer side walls of the housing can support the housings. One suspension bracket can be mounted on a bottom wall of the housing and another suspension bracket of equal length can be mounted on a side wall of the housing that is oriented perpendicular to the bottom wall. Bent flanges on the suspension brackets can be on opposite ends of the respective brackets. A lens cover can cover a light box that holds light sources centrally located in the grill cover. The grill cover can include vent openings that allow incoming air to bypass the light sources that can be located inside of the light box.

Claims

1. An exhaust fan, comprising:

a housing having a top, side walls and bottom with an opening, the housing adapted to be mounted to a ceiling with the top and bottom parallel to the ceiling;

a blower inside of the housing, the blower having a rotational axis perpendicular to the top of the housing;

a motor mount having an opening therethrough, the motor mount having a bent side edge with an outer edge being directly attached to pass through an opening in the top of the housing;

a motor having top, bottom, side walls, and protruding portions on the sidewalls between the top and the bottom, the protruding portions being attached to edges about the opening in the motor mount so that the motor has a lower portion partially inside of the blower, and an upper portion above the blower, such that the motor mount is located about a midway point on the sidewalls of the motor; and

a grill covering the opening of the bottom of the housing, wherein air enters into the housing through the grill, and is exhausted by the motor run blower.

2. The exhaust fan of claim 1, further comprising:

an outlet power box with removable cover, the box being attached to an external side wall outside of the housing.

3. The exhaust fan of claim 1, further comprising:

a first suspension bracket directly mounted along a bottom wall of the housing.

4. The exhaust fan of claim 3, further comprising:

a second suspension bracket directly mounted along a side wall of the housing, the side wall being perpendicular to the bottom wall, the second suspension bracket being substantially identical in length to the first suspension bracket.

5. The exhaust fan of claim 4, wherein the first suspension bracket has one end with a bent mounting flange, and the second suspension bracket has one end with a bent mounting flange, wherein the bent mounting flange on the first suspension bracket faces toward one side direction of the housing, and the bent flange on the second suspension bracket faces toward an opposite side direction of the housing.

6. The exhaust fan of claim 1, further comprising:

a light box supporting a light source beneath a lens cover, and

vent openings about a perimeter edge of the lens cover, wherein incoming air passes through the vent openings to pass into the fan and not passing to the light source inside of the light box.

7. The exhaust fan of claim 1, further comprising:

spring loaded washers for attaching the grill to the housing, without other fasteners.

8. The exhaust fan of claim 1, wherein the housing further includes:

key hole slots for allowing the housing to be directly attached to enlarged headed fasteners adjacent to a ceiling.

9. The exhaust fan of claim 1, wherein the housing further includes:

enlarged headed fasteners for allowing the housing to be directly attached to keyhole slots adjacent to a ceiling.

10. A ventilation fan, comprising:

a housing having a top, side walls and bottom with an opening, the housing adapted to be mounted to a support surface with the top and bottom generally parallel to the support surface;

a blower inside of the housing, the blower having a rotational axis perpendicular to the top of the housing;

a mount board having an opening therethrough, the mount board having a bent side edge with an outer edge being directly attached to pass through an opening in the top of the housing;

a motor for operating the blower, the motor having top, bottom, sidewalls and protrusions on the sidewalls between the top and the bottom, the protrusions being attached to edges about the opening in the mount board so that a lower portion of the motor is partially inside of the blower and an upper portion located above the blower, and the mount board is located about a midway point on the sidewalls of the motor;

a grill covering a bottom of the housing, wherein air enters into the housing through openings in the grill, and is exhausted therefrom by the motor run blower;

a first suspension bracket mounted along a bottom wall of the housing; and

a second suspension bracket mounted along a side wall of the housing, the side wall being perpendicular to the bottom wall.

11. The ventilation fan of claim 10, further comprising:

a light box supporting a light source beneath a lens cover, and

vent openings about a perimeter edge of the lens cover, wherein incoming air passes through the vent openings to pass into the fan and not pass into the light box.

12. The ventilation fan of claim 10, further comprising:

spring loaded washers for attaching the grill to the housing.

13. The ventilation fan of claim 10, wherein the housing further includes:

key hole slots for allowing the housing to be directly attached to enlarged headed fasteners adjacent to a ceiling.

14. The ventilation fan of claim 10, wherein the housing further includes:

enlarged headed fasteners for allowing the housing to be directly attached to keyhole slots adjacent to a ceiling.

15. A ventilation fan, comprising:

a housing having top, side walls and bottom with an opening, the housing adapted to be mounted to a support surface with the top and bottom parallel to the support surface;

a blower in the housing, the blower having a rotational axis perpendicular to the top of the housing;

a mount having an opening therethrough, the motor having a bent edge with an outer edge being directly attached to pass through an opening in the top of the housing;

a motor for operating the blower, the motor having top, bottom, sidewalls and outer edges on the sidewalls between the top and the bottom of the motor, the outer edges being attached to the opening in the mount so that the motor has a lower portion partially inside of the blower, and an upper portion above the blower, and the mount located along the sidewalls of the motor; and

a grill covering a bottom portion of the housing, wherein air enters into the housing through openings in the grill, and is exhausted by the motor run blower.
