Abstract

A cooking and processing appliance includes a container having a lid and a stirring mechanism for rotating at least one processing attachment of a plurality of processing attachments, a housing having a receptacle for receiving the container and having a motor in communication with the stirring mechanism, a heating structure disposed within the housing and a wall of the container, a heating activation system included within the housing and the container, wherein the heating structure defines a heating-active state when the container is received within the receptacle, a mixing activation system, wherein the motor defines a mixing active state when the container is received within the receptacle and the lid is in a closed position and a control in communication with the heating structure and the stirring mechanism.

First claim

What is claimed is:

1. A food processing appliance comprising:
a container having a lid and a stirring mechanism for rotating at least one processing attachment of a plurality of processing attachments, wherein the at least one processing attachment includes a flipping attachment having a flipper paddle adapted to slidably engage a bottom surface of an interior volume of the container;
a housing having a receptacle for receiving the container and having a motor in communication with the stirring mechanism;
a mixing activation system that includes an interlock in communication with the lid, wherein the mixing activation system defines a mixing-active state of the motor when the container is received within the receptacle and the lid is in at least a closed position; and
a control in communication with the stirring mechanism.

2. The food processing appliance of claim 1 , wherein the interlock of the mixing activation system includes an external interlock positioned proximate an exterior of the container.

3. The food processing appliance of claim 2 , wherein the lid is operable between a plurality of rotational positions, and wherein the interlock includes an elongated member that extends from the lid to an area proximate a base of the container, and wherein operation of the lid between the plurality of rotational positions engages the elongated member of the interlock to control the operation of the mixing activation system.

4. The food processing appliance of claim 2 , wherein the lid is operable between a plurality of rotational positions that includes the closed position, an open position and a partially-open position, wherein when the lid is in the closed position, the mixing activation system is in the mixing-active state, wherein when the lid is in the partially-open position, the mixing activation system is in the mixing-active state and engaged only for low-speed operation of the stirring mechanism, and wherein when the lid is in the open position, the mixing activation system is deactivated.

5. The food processing appliance of claim 1 , wherein the flipping attachment includes a post that selectively engages the lid and the interlock when the lid is in the closed position and a partially-open position.

6. The food processing appliance of claim 5 , wherein the mixing activation system further defines the mixing-active state when the post engages a stir assist interlock disposed within the lid.

7. The food processing appliance of claim 1 , wherein the flipping attachment includes an enlarged attachment base that includes a frusto-conical surface having at least one vent slot defined therein.

8. The food processing appliance of claim 7 , wherein the flipper paddle extends from the enlarged attachment base.

9. The food processing appliance of claim 1 , wherein the stirring mechanism of the container is at least partially disposed within a base of the container.

10. A food processing appliance comprising:
a housing having a receptacle, the receptacle including a stirring mechanism;
a container configured to be received by the receptacle, wherein the container includes a shaft, wherein when the container is disposed in the receptacle, the shaft is in communication with the stirring mechanism;
at least one processing attachment selectively disposed on the shaft, wherein the at least one processing attachment includes a flipper attachment having a flipper paddle that extends from an enlarged attachment base that couples with the shaft;
an interlock in communication with the stirring mechanism, wherein the interlock operates to activate, deactivate and modify the stirring mechanism; and
an operable lid rotationally coupled to the container, wherein rotation of the operable lid between a plurality of rotational positions at least partially controls the interlock and the stirring mechanism.

11. The food processing appliance of claim 10 , wherein the enlarged attachment base includes at least one vent aperture that provides for fluid flow between an area under the enlarged attachment base and a remainder of an interior volume of the container.

12. The food processing appliance of claim 11 , wherein the shaft includes an outer surface that defines a spiral profile, wherein when the flipper attachment is engaged with the shaft, the spiral profile of the shaft operates to bias the flipper attachment toward a base of the container.

13. The food processing appliance of claim 10 , wherein the flipper attachment includes a stir assist post that, when disposed on the shaft, engages a stir-assist interlock disposed on an underside of the operable lid when the operable lid is in a closed position, wherein the stir-assist interlock modifies a potential speed of the stirring mechanism when the operable lid is removed from the closed position to at least a partially-open position.

14. The food processing appliance of claim 10 , wherein the interlock includes an interlock tab that is operated between a plurality of inward and outward positions when the operable lid is rotationally operated, wherein operation of the operable lid between the plurality of rotational positions operates the interlock.

15. The food processing appliance of claim 10 , wherein the operable lid is selectively removable from the container to define a lid-removed position of the interlock, wherein the lid-removed position is defined by the stirring mechanism being limited to a slow-speed function.

16. A food processing appliance comprising:
a container having a shaft for rotating a processing attachment;
a housing having a receptacle for receiving the container and having a motor in communication with a stirring mechanism that selectively operates the shaft when the container is received in the receptacle;
an interlock system in communication with the stirring mechanism and including an elongated interlock that at least partially defines a mixing activation system that regulates a speed of the stirring mechanism;
a lid of the container that is rotationally operable between a plurality of rotational positions, wherein when the container is received by the receptacle, rotation of the lid between the plurality of rotational positions operates the elongated interlock, and wherein a mixing-active state of the motor is defined by the lid being in at least one of a closed position and a partially-open position of the plurality of rotational positions, wherein the lid includes a removable seal having a folding portion that exerts an upward bias against the lid and away from the closed position of the lid, wherein a lid latch of the lid selectively secures the lid in the closed position and against the upward bias of the removable seal, and wherein when the lid latch is disengaged, the upward bias of the folding portion of the removable seal rotates the lid away from the closed position such that the lid operates the interlock system to modify the stirring mechanism; and
a control in communication with the stirring mechanism.

17. The food processing appliance of claim 16 , wherein when the container is received by the receptacle, the lid is in communication with the housing, wherein operation of the lid between the plurality of rotational positions operates the elongated interlock relative to the container and an interlock tab contact disposed within the housing.
