Abstract
A cooking appliance includes a base upon which a pot is supported, with a stirrer configured as a lid, for closing an open top of the pot. A tool coupled to a motorized drive of the stirrer extends downwardly into the pot. A heating element is coupled to the base and resiliently biased outwardly from the base to engage the base of the pot. A latch mechanism is provided for releasably connecting the pot to the base. The motorized drive includes a planetary gear set mounted coaxially with a pot axis, and a tool coupling is connected to a planet gear of the planetary gear set to drive the stirring tool in an orbital motion.
Claims28
A cooking appliance comprising:
- a base member;
- a heating element mounted to the base member, the heating element having an outer element surface;
- resilient means urging the heating element outwardly from the base member;
- a pot having a closed bottom and an open top, the bottom having an outer face complementary to the outer element surface, the base member and the bottom of the pot having complementary features for locating the pot on the base;
- a stirrer housing comprising a closure portion for closing the top of the pot;
- a support surface on the base for supporting the pot;
- a motorised drive in the stirrer housing;
- a housing electrical connector and base electrical connector in the stirrer housing and base member. respectively, wherein the housing and base electrical connectors are connected to supply power to the motorised drive;
- a coupling drivingly connected to the motorised drive, the coupling being disposed in the closure portion;
- a tool for engaging the coupling and protruding into the pot, wherein, in an operating position, the resilient means is deflected and holds the outer element surface in contact with the outer face of the bottom of the pot;
- and
- a latch mechanism for releasably connecting the pot to the base, in the operating position.
