Abstract

An ice shaver/blender control apparatus and method includes monitoring the operation of a blender motor as a measure of monitoring the quality and results of blending. By connecting a feedback sensor to the motor, it is possible to determine whether a blend process is complete. It is also possible to identify when cavitation is occurring or about to occur. In another aspect, the blender controls are directed to an improved method for portion blending. The method includes a two-step query to the user to determine both a predetermined portion size and the number of portions to be blended.

providing a blender assembly comprising the blender jar and a blender motor operatively connected to a cutter assembly mounted in the blender jar;

providing a user interface operatively connected to the shaver motor and to the blender motor; and

employing a user input, two-step portion blending process comprising:

selecting, via the user interface, a predefined portion size; and

selecting the number of portions of material to be blended by pushing one of a plurality of portion selection buttons, each button corresponding to a different portion number.

10. The method described in claim 9 , wherein the selecting of a predefined portion size occurs before selecting the number of portions of material to be blended.

11. The method described in claim 9 , wherein the predefined portion size corresponds to a type of drink.

12. The method described in claim 9 , wherein the portions of material correspond to the number of drinks to be served from the blended material.

13. The method described in claim 9 , wherein the portions of material correspond to the amount of ice to be shaved and dispensed into the blender jar.

14. An ice shaver/blender for producing a consistent, blended material, the ice shaver/blender comprising:

(a) an ice shaver assembly comprising an ice hopper, an ice agitator that is connected to and rotatably driven by a shaver motor, a blade mounted adjacent the ice agitator, and a shaved ice chute adapted to dispense shaved ice into a blender jar;

(b) a blender assembly comprising the blender jar and a blender motor operatively connected to a cutter assembly, the cutter assembly mounted in the blender jar for blending material placed within the jar;

(c) an energy control switch that activates and controls the amount of energy delivered to the blender motor during operation of the motor;

(d) a feedback sensor electrically connected to the energy control switch, the feedback sensor adapted to detect an attribute associated with the operation of the blender motor and send a signal to the energy control switch based on the attribute detected; and
