Abstract

A blending system includes a container or housing, a blade assembly, and an insert are described herein. The insert is disposed in or on the container or housing. The blade assembly includes a drive shaft. The drive shaft is rotatable. A magnet is attached to the drive shaft. Rotation of the magnet induces current in the insert. The current induces heat.

First claim

What is claimed is:

1. A blending system for blending foodstuff, comprising:
a blender base having a motor;
a container selectively attachable to the blender base;
a blade assembly operatively attached to the container, the blade assembly comprising a drive shaft that is operatively driven by the motor to blend the foodstuff; and
an insert embedded within the container, wherein rotation of the drive shaft operatively induces current within the insert.

2. The blending system of claim 1 , wherein the blade assembly further comprises at least one blade, and wherein the blade is magnetized.

3. The blending system of claim 1 , wherein the blade assembly further comprises at least one magnet operatively attached to the drive shaft.

4. The blending system of claim 1 , further comprising at least one wireless communication device.

5. The blending system of claim 1 , wherein the insert is hermetically sealed.

6. The blending system of claim 1 , wherein the container further comprises a clutch configured to selectively induce heat in the insert by driving the drive shaft.

7. The blending system of claim 1 , further comprising at least one sensor.

8. The blending system of claim 7 , wherein the at least one sensor is a temperature sensor.

9. A blending system for blending foodstuff, comprising:
a blender base having a motor;
a container selectively attachable to the blender base;
a blade assembly operatively attached to the container, the blade assembly comprising a drive shaft that is operatively driven by the motor to blend the foodstuff; and
an insert embedded within the container, wherein rotation of the drive shaft relative to the insert operatively induces heat in the container.

10. The blending system of claim 9 , wherein the insert is magnetized.

11. The blending system of claim 9 , wherein the blade assembly further comprises at least one blade, and wherein the blade is magnetized.

12. The blending system of claim 9 , further comprising at least one wireless communication device.

13. The blending system of claim 9 , wherein the insert is hermetically sealed.

14. The blending system of claim 9 , further comprising at least one sensor.

15. The blending system of claim 14 , wherein the at least one sensor is a temperature sensor.

16. The blending system of claim 9 , wherein the container further comprises a clutch configured to selectively induce heat in the insert by driving the drive shaft.

17. A blender container for blending foodstuff, comprising:
a container body having at least one sidewall defining a cavity;
a lid operatively attachable to the container body;
a blade assembly disposed within the cavity, the blade assembly comprising one or more blades and a rotatable drive shaft, wherein the rotatable drive shaft drives the one or more blades to blend the foodstuff contained in the blender container; and
an insert disposed within the blender container, wherein rotation of the rotatable drive shaft operatively induces current within the insert.

18. The blender container of claim 17 , wherein the blade assembly comprises at least one magnetized blade.

19. The blender container of claim 17 , wherein the blade assembly further comprises at least one magnet operatively coupled to the drive shaft.

20. The blender container of claim 17 , wherein the container further comprises a clutch capable of selectively coupling the insert to the rotatable drive shaft.

21. The blender container of claim 17 , wherein at least one blade of the blade assembly is configured to interact with the insert to inductively heat foodstuff within the cavity.

22. The blending system of claim 1 , wherein at least one blade of the blade assembly is configured to interact with the insert to inductively heat foodstuff within the container.
