Abstract

A blender system is shown and described herein. In one aspect, the blender system includes a base with an interior and an exterior formed by a housing. The housing may include an air inlet port and an exhaust port. The interior of the base includes a motor bore forming an air pathway connecting the air inlet port to the exhaust port. The motor bore also includes an entry aperture fluidly connecting the motor bore to the air inlet port. The entry aperture is indirectly in line with the air inlet port. The exit aperture fluidly connects the motor bore to the exhaust port, and the exit aperture is indirectly in line with the exhaust port.

First claim

What is claimed is:

1. A blender base, comprising:
a housing comprising an air inlet aperture;
a motor disposed within a motor bore in the housing;
a diffuser disposed in the housing and comprising a diffuser aperture operatively in fluid communication with the air inlet aperture;
a fan operatively forcing air to travel in a path from the air inlet aperture, about the diffuser, and then through the diffuser aperture; and
a motor baffle member positioned about at least a portion of the motor, wherein the motor baffle member restricts airflow, forcing air through the motor bore,
wherein the diffuser aperture is out of a line of sight of the air inlet aperture and the air inlet aperture is positioned above the fan.

2. The blender base of claim 1 , wherein the diffuser comprises a curved wall.

3. The blender base of claim 1 , wherein the diffuser comprises a wall comprising at least one corner.

4. The blender base of claim 1 , wherein the housing further comprises an exhaust aperture.

5. The blender base of claim 4 , wherein the exhaust aperture is out of a line of sight of the fan.

6. The blender base of claim 1 , wherein the motor baffle member comprises a body comprising an aperture having a perimeter, wherein the perimeter is positioned about the at least a portion of the motor.

7. The blender base of claim 6 , wherein the body is attached to the housing at a joint.

8. The blender base of claim 1 , further comprising a fan chamber disposed in the housing, wherein the fan is disposed within the fan chamber.

9. The blender base of claim 1 , wherein the motor operatively drives the fan.

10. A blender base, comprising:
a housing;
a motor disposed within the housing and comprising a motor bore;
a motor baffle member disposed about at least a portion of the motor; and
a fan disposed in an air passageway within the housing,
wherein the motor baffle member operatively directs all air from the fan through only the motor bore and out of the housing such that the air from the fan is restricted from circulating about the housing.

11. The blender base of claim 10 , wherein the motor baffle member comprises a body comprising an aperture having a perimeter, wherein the perimeter is positioned about at least a portion of the motor.

12. The blender base of claim 11 , wherein the body is attached to the housing at a joint.

13. The blender base of claim 10 , wherein the housing further comprises a fan chamber; and
wherein a gasket is positioned between the motor baffle member and the fan.

14. The blender base of claim 13 , wherein the gasket dampens vibrations between the motor baffle member and the fan chamber.

15. The blender base of claim 13 , wherein the motor baffle member comprises a body having an aperture, the aperture operatively in a closely fitting engagement with at least a portion of the motor.

16. The blender base of claim 13 , wherein the gasket generally seals the fan chamber from other portions of the housing.

17. The blender base of claim 10 , wherein the housing further comprises a user interface disposed on a first side of the housing.

18. A blender system, comprising:
a blender base comprising a housing having an air inlet port and defining an air passageway;
a motor bore positioned within the housing and a motor disposed within the motor bore;
a motor baffle member operatively restricting the air passageway from circumventing the motor bore;
a fan disposed in the air passageway; and
a diffuser disposed between the air inlet port and the fan,
wherein the fan operatively pulls air through the diffuser and pushes the air through the motor bore.

19. The blender system of claim 18 , wherein the diffuser defines an aperture and is disposed in the housing,
the aperture being disposed generally opposed to the air inlet port.

20. The blender system of claim 18 , further comprising a fan chamber housing the fan and a gasket, wherein the gasket dampens vibrations between the motor baffle member and the fan chamber.
