Abstract

Apparatus, systems and methods of 70 (seventy) CFM (cubic feet per minute) ventilation fans for bathrooms with recessed can with light and having the motor partially inside and beneath the blower wheel. A housing for the bath fan can be attached to joists in the ceiling by a long telescoping mounting brackets. The motor and blower wheel can be attached to a mounting plate inside of the housing, which can be removed as a single unit to allow the motor to be easily replaced or repaired, and also to allow for the inside of the housing to be inspected during and after installation of the exhaust fan. A ring about the light can have vents that receive incoming air into the fan, which is exhausted therefrom by the blower. Seals such as elastomeric rings can seal the bottom of the can to the light, and the top end of the can to the decorative ring shaped pan. A vertical panel can separate a first compartment having the motor and blower from a second adjacent compartment having the light.

Claims

1. A ventilation exhaust fan, comprising:

a housing having top, side walls and bottom, and outlet;

a blower wheel inside of the housing;

a motor in the housing for rotating the blower wheel;

a recessed can mounted to the bottom of the housing adjacent to the wheel and motor, the recessed can having an interior end;

a light in the recessed can adjacent to the interior end;

a solid vertical panel in the housing between the recessed can and the motor mounted blower wheel for separating the recessed can from the motor, the solid vertical panel having an upper end attached to the housing, the vertical panel separating a first compartment having the motor and blower wheel, from a second compartment having the recessed can and the light, the first compartment being side by side with the second compartment, with the first compartment having a closed bottom, beneath the motor and the blower wheel, the solid vertical panel further preventing airflow from the blower wheel contacting the light.

2. The exhaust ventilation fan of claim 1, wherein the solid vertical panel includes:

a first male plug and a first female receptacle on a bent edge of the solid vertical panel connecting power to the light; and

a second male plug and a second female receptacle on the bent edge of the solid vertical panel connecting power to the motor.

3. The ventilation exhaust fan of claim 1, wherein the motor is an approximately 70 (seventy) CFM (cubic feet per minute) generating motor.

4. The ventilating exhaust fan of claim 1, further comprising:

an elongated side telescoping bracket directly mounted along the housing for mounting the housing to structural supports within a ceiling.

5. The ventilating exhaust fan of claim 1, wherein the recessed can includes:

a recessed shade.

6. The ventilating exhaust fan of claim 5, further comprising:

a pan having vents about the recessed shade, wherein air enters through the vents into the exhaust fan and passes about an exterior surface of the light shade.

7. The ventilating exhaust fan of claim 6, further comprising:

a sealing ring for sealing the can to the pan, so that moisture and air does not pass into the recessed can.

8. A ventilation exhaust fan, comprising:

a housing having sides, top and bottom;

a blower inside of the housing;

a motor in the housing for running the blower;

a light mounted in a recess in the bottom of the housing; and

a solid vertical panel in the housing between and separating the recess from the motor with the blower, the vertical panel separating a first compartment having the motor and blower, from a second compartment having the recess and the light, the first compartment being adjacent the second compartment, the solid vertical panel further preventing airflow from the blower contacting the light.

9. The ventilation exhaust fan of claim 8, wherein the first compartment includes:

a closed bottom wall beneath the motor and the blower.

10. The ventilation exhaust fan of claim 8, wherein the solid vertical panel includes:

a first male plug and a first female receptacle on a bent edge of the solid vertical panel connecting power to the light; and

a second male plug and a second female receptacle on the bent edge of the solid vertical panel connecting power to the motor.

11. The ventilation exhaust fan of claim 8, further comprising:

a ring shaped pan having vents about a perimeter edge of the pan positioned about the recess, the vents for allowing incoming air to pass into the housing by the blower.

12. The ventilation exhaust fan of claim 8, further comprising:

a sealing member attached to the recess for preventing the incoming air from entering into the recess and contacting the light.

13. The ventilation exhaust fan of claim 11, wherein the sealing member includes:

a sealing ring for sealing the recess to the ring shaped pan, so that moisture and air does not pass into the recess.

14. The ventilation exhaust fan of claim 12, wherein the sealing member includes;

a first sealing ring for sealing the recess to the ring shaped pan, so that moisture and air does not pass into the recess; and

a second sealing ring for sealing the recess to the light, so that moisture and air does not pass into the recess.

15. The ventilation exhaust fan of claim 8, further comprising:

a motor mounting plate having an opening therethrough; and

a generally U-shaped motor bracket attached to the motor mounting plate for mounting the motor in the opening of the motor mounting plate, with the blower to one side of the motor mounting plate, wherein the motor mounting plate with the mounted motor and blower are both insertable into the housing as a single unit, and are removable from the housing as the single unit.

16. The ventilation exhaust fan of claim 8, further comprising:

an elongated side telescoping bracket directly mounted along the housing for mounting the housing to structural supports within a ceiling.

17. A ventilating exhaust fan comprising:

a housing having sides, top, bottom, and an outlet;

a blower inside of the housing;

a motor for running the blower;

a light attached to the housing; and

a solid vertical panel in the housing between and separating the motor with the blower wheel, and the light, the vertical panel separating a first compartment having the motor and blower, from a second compartment, the first compartment being adjacent the second compartment, with the first compartment having a closed bottom under the motor and the blower, the solid vertical panel further preventing airflow from the blower from contacting the light.

18. The ventilating exhaust fan of claim 17, wherein the solid vertical panel includes:

a first male plug and a first female receptacle on a bent edge of the solid vertical panel connecting power to the light; and

a second male plug and a second female receptacle on the bent edge of the solid vertical panel connecting power to the motor.

19. The ventilating exhaust fan of claim 17, further comprising:

vents about the light for allowing incoming air to pass into the vents.

20. The ventilating exhaust fan of claim 19, further comprising:

a seal for preventing air coming into the housing from contacting the light.
