## Abstract

A food processor is provided. The food processor comprises a base, a container removably mountable on the base for receiving food, a rotatable mixing member disposed within the container for processing the food, an induction coil enclosing at least a portion of the container, and an electrically conducting member removably receivable within the container in a substantially parallel relationship with a surface defined by at least a portion of the induction coil.

## Claims

### Claim 1

A food processor comprising:
a base;
a container removably mountable on the base that receives food, the container comprising a ledge formed on an inner wall of the container;
an electrically conducting member removably receivable within the container, the electrically conducting member mountable on the ledge;
a rotatable mixing member disposed within the container that processes the food, wherein the ledge is formed at a height above the rotatable mixing meber; and
an induction heating device supported by the base and being constructed and arranged to enclose at least a portion of a sidewall of the container.

### Claim 2 (depends on 1)

The food processor of claim 1, further comprising an eddy current sensor that detects a presence of the electrically conducting member within the container.

### Claim 3 (depends on 1)

The food processor of claim 1, wherein at least a portion of the container is made of transparent material.

### Claim 4 (depends on 1)

The food processor of claim 1, wherein at least a portion of the container is made of glass or plastic.

### Claim 5 (depends on 1)

The food processor of claim 1, wherein the electrically conducting member is a ferromagnetic metal.

### Claim 6 (depends on 1)

The food processor of claim 1, wherein the electrically conducting member is ring-shaped.

### Claim 7 (depends on 1)

The food processor of claim 1, wherein the electrically conducting member comprises a support frame that couples to at least one of the container and a lid of the food processor.

### Claim 8 (depends on 1)

The food processor of claim 1, wherein the induction heating device is an induction coil.

### Claim 9 (depends on 1)

The food processor of claim 1, further comprising a temperature sensor disposed within the container.

### Claim 10 (depends on 1)

The food processor of claim 1, further comprising a lid that covers the container.

### Claim 11 (depends on 10)

The food processor of claim 10, further comprising a device that detects a first lid location wherein the lid is in position relative to the container, and a second lid location wherein the lid is out of position relative to the container.

### Claim 12 (depends on 1)

The food processor of claim 1, wherein a food contacting surface of the electrically conducting member is covered by a layer of metal or alloy having a higher thermal conductivity than the electrically conducting member.
