Lid locking system and cooking apparatus having lid lock

摘要

A cooking apparatus includes a cooking chamber for receiving a. cooking medium, a lid configured to cover the cooking chamber, and a lid locking system. The lid locking system includes a pressure lock pin coupled to a movable diaphragm, an electronic lock pin coupled to the lid, and a latch. The latch includes a pressure lock pin aperture formed therein to accommodate the pressure lock pin, and an electronic lock pin aperture formed therein to accommodate the electronic lock pin. The pressure lock pin engages the latch in response to pressure in the cooking chamber exceeding a predetermined threshold, and the electronic lock pin engages the latch in response to a lock signal from a controller.

1. A cooking apparatus comprising:
a cooking chamber configured to receive a cooking medium therein; a lid configured to cover the cooking chamber, the lid comprising a diaphragm; and a lid locking system comprising:
a pressure lock pin coupled to the diaphragm;an electronic lock pin coupled to the lid; anda latch comprising:
a pressure lock pin aperture formed therein configured to accommodate the pressure lock pin, andan electronic lock pin aperture firmed therein configured to accommodate the electronic lock pin, wherein the pressure lock pin is configured to automatically engage with the pressure lock pin aperture in response to flexing of the diaphragm when pressure in the cooking chamber exceeds a predetermined threshold, and the electronic lock pin is configured to selectively engage with electronic lock pin aperture in response to a lock signal from a controller generated in response to at least one of a cook cycle start and feedback from a pressure sensor configured to detect when the pressure in the cooking chamber exceeds another predetermined threshold.
