Abstract

Apparatus, systems and methods of 50/60 CFM exhaust and ventilation fans for bathrooms with flaps/ears that allow the housings to mount directly to joists and/or other structural members inside of a ceiling or inside of a wall. The housing can include a mounting plate having a motor with attached impeller thereon, wherein the mounting plate with motor and attached impeller can be removed as a single unit from the housing for accessing and inspecting interior wire connections during inspection and for ease in replacing parts such as burned out motors overtime.

Claims

1. An exhaust fan, comprising:

a housing having side walls, a top and a bottom with an opening;

a blower inside of the housing;

a motor for running the blower; and

at least one external flap adaptable for mounting the housing to a support member, wherein the flap includes a base plate with a flat front face and a flat rear face, the flat rear face fastened to an exterior of the housing, and a swinging flat flap plate, the swinging flat flap plate having a side attached by a hinge to a side of the base plate, the flap plate having a fastening opening for mounting the housing to the support member, wherein the flap plate is bendable from a coplanar position with the base plate to pivot about the hinge relative to the base plate.

2. The exhaust fan of claim 1, wherein the motor is a 50 (fifty) CFM (cubic feet per minute) generating motor.

3. The exhaust fan of claim 1, wherein the motor is a 60 (sixty) CFM (cubic feet per minute) generating motor.

4. The exhaust fan of claim 1, wherein the motor includes:

an open motor with C-frame.

5. The exhaust fan of claim 1, wherein the fastening opening includes:

an opening and a keyhole slot.

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

a removable mounting plate having a central opening therethrough with the motor and the blower pre-attached to the mounting plate the mounting plate attached by removable fasteners to internally facing side portions along the side walls between the top and the bottom, the motor being substantially on one side of the plate and the blower being substantially on an opposite side of the plate with a rotatable axle portion which attaches the motor to the impeller, wherein the mounting plate with the motor and blower are removable as a single piece from the inside of the housing by removing the removable fasteners.

7. The exhaust fan of claim 6, wherein the internally facing side portions includes:

side ledge clips, and the mounting plate sits on the side ledge clips and the removable fasteners are selected from screws and bolts.

8. The exhaust fan of claim 1, wherein the base plate is a single base plate.

9. The exhaust fan of claim 1, wherein the flap plate is a singular rectangular flap plate.

10. A ceiling mounted exhaust fan, comprising:

a housing having side walls, an exhaust side opening, a top and a bottom with an opening, the top being parallel to and adapted to be above a ceiling, with the bottom adjacent to an opening in the ceiling;

a motor attached to an impeller, both inside of the housing; and

at least one external flap adaptable for mounting the housing to a support, wherein the flap includes a base plate with a flat front face and a flat rear face, the flat rear face fastened to an exterior of the housing, and a swinging flap plate with a flat front face and a flat rear face, the swinging flap plate having one side attached by a hinge to one side of the base plate, the flap plate having an opening for mounting the housing to the support, wherein the flap plate is bendable from a coplanar position with the base plate to pivot about the hinge relative to the base plate.

11. The exhaust fan of claim 10, wherein the motor is a 50 (fifty) CFM (cubic feet per minute) generating motor.

12. The exhaust fan of claim 10, wherein the motor is a 60 (sixty) CFM (cubic feet per minute) generating motor.

13. The exhaust fan of claim 10, wherein the fastening opening includes:

an opening and a keyhole slot.

14. The exhaust fan of claim 10, wherein the flap plate is a singular rectangular flap plate.

15. A ceiling exhaust fan, comprising:

a housing having side walls, a side exhaust, a top above and parallel to a ceiling in which the exhaust fan is adapted to be installed, and a bottom with an opening therethrough adjacent to an opening in the ceiling;

a blower wheel inside of the housing;

a motor for running the blower wheel; and

at least one external flap adaptable for mounting the housing to a support, wherein the flap includes a base plate having a flat front face and a flat rear face, the flat rear face fastened to an exterior of the housing, and a swinging flap plate having a side attached by a hinge to one side of the base plate, the flap plate having an opening for mounting the housing to the support, wherein the flap plate is bendable from a coplanar position with the base plate to pivot relative to the base plate.

16. The ceiling exhaust fan of claim 15, wherein the flap plate is a singular rectangular flap plate.

17. The ceiling exhaust fan of claim 15, wherein the fastening opening includes:

an opening and a keyhole slot.
