Abstract

A blending system is shown and described herein. The blending system may include a base including a motor, a blade selectively and operably engaged with the base, where the motor rotates the blade, a container having an open end and a lid configured to cover the open end. The blending system may also include an interlock system that may include a plurality of induction coils positioned on the base and the container and be in electrical communication with at least one lid sensor, wherein the power is translated through the induction coils to engage a switch device to complete a power circuit to allow a user to operate the motor of the blender.

First claim

What is claimed is:

1. An interlocking blending system comprising:
a base comprising a motor, power circuit comprising a switch and a first set of inductive coils; and
a container including a second set of inductive coils that selectively inductively couples with the first set of inductive coils when the second set of inductive coils are operatively positioned on top of the first set of inductive coils;
wherein the base selectively permits operation of the motor based on the inductive coupling of the first set of coils and the second set of coils when the container is operatively positioned on top of the base, which causes the switch device to be in closed state completing the power circuit providing power to the motor.

2. The blending system of claim 1 , wherein the first set of inductive coils includes at least one transmitter coil and at least one receiving coil.

3. The blending system of claim 2 , wherein the second set of inductive coils includes at least one transmitter coil and at least one receiving coil.

4. The blending system of claim 3 , wherein the at least one transmitter coil of the first set of inductive coils induces current in the at least one receiving coil of the second set of inductive coils in response to power supplied to the at least one transmitter coil of the first set of inductive coils when the container is operatively attached to the base.

5. The blending system of claim 2 , wherein the transmitter coil and the receiving coil are generally concentric.

6. The blending system of claim 1 , wherein the second set of inductive coils includes an inner coil and an outer coil.

7. The blending system of claim 5 , wherein the outer coil and the inner coil are generally concentric.

8. The blending system of claim 1 , wherein the coils of the first set of inductive coils are generally similar in dimensions to coils of the second set of inductive coils.

9. The blending system of claim 1 , wherein the base comprises a sensor that monitors change in an electrical property of the first set of coils.

10. The blending system of claim 9 , wherein the base determines whether the container is attached to the base based on the monitored change in the electrical property.

11. The blending system of claim 9 , further comprising a lid, wherein at least one of the lid or the container alter the electrical property of the first set of coils when the lid or the container are operatively coupled to the blender base.

12. The blending system of claim 1 , wherein the first set of inductive coils and second set of conductive coils are each planar.

13. The blending system of claim 1 , wherein the first set of inductive coils are adjacent to each other.

14. The blending system of claim 1 , wherein the container is capable of being positioned on top of the base in more than one position to provide inductive coupling of the first set of coils and the second set of coils.

15. An interlocking blending system comprising:
a base including a motor and a first set of inductive coils; and
a container including a second set of inductive coils that selectively inductively couples with the first set of inductive coils when the second set of inductive coils are operatively positioned on top of the first set of inductive coils;
wherein the base selectively permits operation of the motor based on the inductive coupling of the first set of coils and the second set of coils when the container is operatively positioned on top of the base,
wherein the first set of inductive coils includes at least one transmitter coil and at least one receiving coil, and wherein the base comprises a switch that in response to induced current in the at least one receiving coil of the first set of inductive coils moves to the closed position to allow operation of the motor.

16. An interlocking blending system comprising:
a base including a motor and a first set of inductive coils; and
a container including a second set of inductive coils that selectively inductively couples with the first set of inductive coils when the second set of inductive coils are operatively positioned on top of the first set of inductive coils;
wherein the base comprises a switch that selectively permits operation of the motor based on the inductive coupling of the first set of coils and the second set of coils when the container is operatively positioned on top of the base, wherein the first set of inductive coils includes at least one transmitter coil and at least one receiving coil and the second set of inductive coils includes at least one transmitter coil and at least one receiving coil, and wherein the at least one transmitter coil of the first set of inductive coils induces current in the at least one receiving coil of the second set of inductive coils in response to power supplied to the at least one transmitter coil of the first set of inductive coils when the container is operatively attached to the base and wherein the switch moves to closed position.

17. The interlocking blending system of claim 16 , wherein the at least one transmitter coil of the second set of inductive coils induces current in the at least one receiving coil of the first set of inductive coils in response to current induced in the receiving coil of the second set of inductive coils when the container is operatively attached to the base.
