THERMOSTATIC FAN CLUTCH FOR BLENDER NOISE REDUCTION AND MOTOR EFFICIENCY IMPROVEMENT

1 . A blending apparatus comprising: a motor, a fan, and a thermostatic fan clutch.

2 . The blending apparatus of claim 1 , wherein the fan is engaged with a secondary drive shaft of the motor and wherein the thermostatic fan clutch engages the secondary drive shaft to cause the fan to rotate.

3 . The blending apparatus of claim 1 , wherein the fan is engaged with a secondary drive shaft of the motor and wherein the thermostatic fan clutch disengages the secondary drive shaft to cause the fan to stop rotating.

4 . The blending apparatus of claim 1 , wherein the fan is engaged with a secondary drive shaft of the motor and wherein the thermostatic fan clutch partially engages the secondary drive shaft to cause the fan to rotate at a controlled speed or an adjusted speed.

5 . The blending apparatus of claim 1 , wherein the fan is engaged with a secondary drive shaft of the motor and wherein the thermostatic fan clutch partially disengages the secondary drive shaft to cause the fan to rotate at a controlled speed or an adjusted speed.

6 . The blending apparatus of claim 1 , wherein the fan is engaged with a secondary drive shaft of the motor and wherein the thermostatic fan clutch engages or disengages or both engages and disengages the secondary drive shaft based on a temperature of the motor.

7 . The blending apparatus of claim 6 , wherein the thermostatic fan clutch engages the secondary drive shaft to cause the fan to rotate if the motor is determined to be at or above an engagement temperature.

8 . The blending apparatus of claim 6 , wherein the thermostatic fan clutch disengages the secondary drive shaft to cause the fan to stop rotating if the temperature of the motor is determined to be at or below a disengagement temperature.

9 . The blending apparatus of claim 6 , wherein the thermostatic fan clutch partially engages the secondary drive shaft to cause the fan to rotate at a controlled speed or an adjusted speed if the temperature of the motor exhibits or exceeds a predetermined partial-engagement temperature.

10 . The blending apparatus of claim 6 , wherein the thermostatic fan clutch partially disengages the secondary drive shaft to cause the fan to rotate at a controlled speed or an adjusted speed if the temperature of the motor exhibits or falls below a predetermined partial-disengagement temperature.

11 . The blending apparatus of claim 1 , wherein the thermostatic fan clutch comprises at least one of a bi-metallic coil, a fluid, and a mechanical engagement to engage, disengage, or both engage and disengage a secondary drive shaft of the motor to cause the fan to at least one of rotate and stop rotating.

12 . The blending apparatus of claim 11 , wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement engages, disengages or both engages and disengages the secondary drive shaft based on a temperature of the motor.

13 . The blending apparatus of claim 12 , wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement engages the secondary drive shaft to cause the fan to rotate if the motor is at or above an engagement temperature.

14 . The blending apparatus of claim 12 , wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement disengages the secondary drive shaft to cause the fan to stop rotating if the motor is at or below a disengagement temperature.

15 . The blending apparatus of claim 11 , wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement partially engages, partially disengages, or both partially engages and disengages the secondary drive shaft of the motor to cause the fan to rotate at a controlled speed or an adjusted speed.

16 . The blending apparatus of claim 15 , wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement partially engages the secondary drive shaft to cause the fan to rotate at a controlled speed or an adjusted speed if the motor is at or above a partial-engagement temperature.

17 . The blending apparatus of claim 15 , wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement partially disengages the secondary drive shaft to cause the fan to rotate at a controlled speed or an adjusted speed if the motor is at or below a partial-disengagement temperature.

18 . A blending apparatus comprising: a motor, a fan, and a thermostatic fan clutch, wherein the thermostatic fan clutch engages, disengages, or both engages and disengages a secondary drive shaft of the motor to cause the fan to rotate or stop rotating or both, and wherein the thermostatic fan clutch engages, disengages, or both engages and disengages the secondary drive shaft based on a temperature of the motor.

19 . The blending apparatus of claim 18 , wherein the thermostatic fan clutch comprises at least one of a bi-metallic coil, a fluid, and a mechanical engagement, wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement engages and/or disengages the secondary drive shaft to cause the fan to rotate or stop rotating, and wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement engages, disengages, or both engages and disengages the secondary drive shaft based on a temperature of the motor.

20 . The blending apparatus of claim 18 , wherein the thermostatic fan clutch comprises at least one of a bi-metallic coil, a fluid, and a mechanical engagement, wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement partially engages, partially disengages, or both partially engages and disengages the secondary drive shaft to cause the fan to rotate at a controlled speed or an adjusted speed, and wherein the at least one of a bi-metallic coil, a fluid, and a mechanical engagement partially engages, partially disengages, or both partially engages and disengages the secondary drive shaft based on a temperature of the motor.
