Abstract

A blending system includes a blender base. The blender base includes a housing. The housing defines a cavity. A motor is disposed within the cavity. An insulating material is disposed between the housing and the cavity. The insulating material defines air channels. The air channels are in fluid communication with a fan. The fan operates independent of the motor. The motor is suspended from a suspension bracket. The suspension bracket isolates the motor from the housing.

First claim

What is claimed is:

1 . A blender system, comprising:
a blender base comprising:
a housing comprising a base wall and one or more side walls, the housing defining a cavity;
a motor disposed within the cavity of the housing, the motor positioned to define a space within the cavity between the motor and the one or more side walls of the housing;
a fan operatively driven by a second motor; and
an insulating material dispersed throughout the space of the cavity, the insulating material contacting at least a portion of the one or more side walls of the housing and at least a portion of the motor, the insulating material defining at least one air channel therethrough, and the insulating material comprising a foam material dispersed throughout the space of the cavity.

2 . The blender system of claim 1 , wherein insulating material at least partially supports the motor.

3 . The blender system of claim 1 , further comprising a suspension bracket disposed between the motor and the housing, wherein the motor is operatively suspended from the suspension bracket.

4 . The blender system of claim 3 , wherein the suspension bracket comprises a semi-ridged thermoplastic elastomer.

5 . The blender system of claim 1 , wherein the at least one air channel defined by the insulating material allows for passage of ambient air into the housing and to the motor.

6 . The blender system of claim 1 , wherein the at least one air channel defined by the insulating material allows for passage of air from within the housing to an exhaust of the housing.

7 . The blender of claim 1 , wherein the insulating material generally fills open space in the cavity except for at least one air channel.

8 . The blender system of claim 1 , further comprising a controller that operatively controls the fan at a different speed than the motor.

9 . The blender system of claim 1 , wherein the blender base further comprises at least one sensor operatively sensing a temperature within the housing.

10 . The blender system of claim 1 , wherein the fan is configured to be driven when the motor is not operating.

11 . A blender system, comprising:
a blender container operatively coupled to a blade assembly; and a blender base comprising:
a housing comprising a base wall and one or more side walls, the housing defining a cavity;
a motor disposed within the cavity of the housing, the motor positioned to define a space within the cavity between the motor and the one or more side walls of the housing, wherein the motor operatively drives the blade assembly;
a fan comprising a fan motor, the fan configured to be driven by the motor and the fan motor to force air through the housing; and
an insulating material dispersed throughout the space of the cavity and between the motor and the housing, the insulating material contacting at least a portion of the one or more side walls of the housing and at least a portion of the motor, wherein the insulating material defines at least one air channel in fluid communication with the fan,
wherein the blender container is operatively attached to the blender base.

12 . The blender system of claim 11 , wherein the insulating material comprises a foam material.

13 . The blender system of claim 11 , wherein the insulating material contacts at least a portion of the housing and at least a portion of the motor.

14 . The blender system of claim 13 , wherein the insulating material occupies space between the housing and the motor, such that the at least one air channel defines the only open space within the cavity.

15 . The blender system of claim 11 , wherein the at least one air channel includes at least one baffle.

16 . The blender system of claim 11 , wherein the insulating material comprises compressed insulating material between the housing and the motor.

17 . A blender system comprising:
a blender base comprising a housing comprising a cavity defined by a base wall and one or more side walls, wherein the housing houses a motor, a motor drive shaft, a fan comprising a fan motor, and a control board within the cavity, wherein the motor is positioned to define a space within the cavity between the motor and the one or more side walls, and wherein the fan is configured to be driven by the motor and the fan motor; and a sound insulating material dispersed throughout the space of the cavity, the sound insulating material contacting at least a portion of the one or more side walls and at least a portion of the motor, and wherein the sound insulating material is disposed around the motor, the motor drive shaft, the fan, and the control board.

18 . The blender system of claim 17 , wherein the sound insulating material further defines an air flow path between at least one air inlet and at least one exhaust.

19 . The blender system of claim 18 , wherein the fan is disposed within the air flow path between the motor and the at least one exhaust.

20 . The blender system of claim 17 , wherein the sound insulating material supports at least one of the motor or the fan.
