Abstract: A cooking appliance includes a pot lid, a pot body, and a pot lid. The pot lid has an oval cross section with a long axis and a short axis orthogonal to each other. The pot body includes a limiting boss provided at an upper surface of the pot body. The limiting boss is configured to abut against an outer peripheral edge of the pot lid when the pot lid is closed. The pot lid locking assembly is configured to lock the pot lid in a closed state. The pot lid locking assembly includes at least one of a lid locking part disposed at the pot lid or a pot locking part disposed at the pot body.

Abstract: An inner cover assembly and a lid for a cooking utensil. The inner cover assembly includes: an inner cover having a major axis and a minor axis orthogonal each other; and a seal ring fitted over an outer peripheral edge of the inner cover. When the seal ring is not fitted over the inner cover in a natural state, a smooth transition is provided along an extending direction of the seal ring, and a maximum inner diameter of the seal ring is less than a length of the major axis of the inner cover.

Abstract: A pressure cooking apparatus, a method and device for controlling the same are provided. During a heating process of the apparatus, the device detects a pressure value inside the inner liner, a first temperature value when the detected pressure value rises to a first preset pressure threshold, and a second temperature value when the detected pressure value drops from the preset first pressure threshold to a second preset pressure threshold. Next the device acquires a temperature reference value according to a preset setting strategy using the first temperature value and the second temperature value and then compares a current temperature value detected by the temperature sensor with the temperature reference value. Finally, the device starts or stops the heating process based on the comparison result, thus reducing the on/off frequency of the apparatus and controlling the pressure inside the cooking apparatus more precisely and smoothly.
