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 bore disposed within a motor chamber within the housing, the motor chamber defining an entry aperture, an exit aperture, and a flowpath between the entry aperture the exit aperture, the flowpath including at least a portion of the motor bore;
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
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 , further comprising a motor baffle member positioned about at least a portion of a motor, 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 a motor operatively drives the fan.

10. A blender base, comprising:
a housing;
a motor chamber disposed within the housing and comprising a motor bore, the motor chamber defining an entry aperture and an exit aperture; and
a fan disposed in an air passageway within the housing,
wherein the motor chamber 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 housing includes an air inlet port that comprises a first grill.

12. The blender base of claim 11 , wherein the housing comprises a second grill disposed within the housing.

13. The blender base of claim 10 , wherein the housing further comprises an upper chamber, wherein the upper chamber is disposed between the housing and the motor chamber.

14. The blender base of claim 13 , wherein the fan operatively circulates air in the upper chamber.

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

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

17. The blender base of claim 16 , wherein an air inlet is disposed on a second side of the housing, wherein the second side is generally opposed to the first side.

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 chamber defining an entry aperture and an exit aperture 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, the fan chamber comprising a fan inlet operatively receiving air flow from the air inlet; wherein the fan inlet is out of the line of site of the air inlet port.
