An electric cooker capable of changing between a high-pressure mode and a non-pressure mode and cooking a menu corresponding to the changed mode. The electric cooker includes a main body having an accommodation space therein to receive an inner pot, a lid coupled to the upper portion of the main body to be opened and closed, a pressure conversion part for selecting a high-pressure mode and a non-pressure mode by opening and closing a plurality of discharge paths configured to pass through and to block the gap between the inside of the inner pot and the outside of the lid, a sensor for sensing the high-pressure mode or the non-pressure mode selected by the pressure conversion part, and a controller for determining the pressure mode based on the sensing signal from the sensor among the pressure modes at least including the high-pressure mode and the non-pressure mode.

The invention concerns a food preparation device 1 comprising a food preparation pot 2, a heating element 3 for heating food 4 in the food preparation pot 2, a tool 5 for blending and/or comminuting food 4 in the food preparation pot 2, a lid 6, 7 for the food preparation pot 2, and an electric motor 8 for rotating the tool 5. A monitoring unit monitors a power input of the electric motor 8 for detecting an overpressure in the food preparation pot 2. The invention also concerns a method and a computer program product. A very reliable detection of overpressure can thereby be enabled.

A cooking machine equipped with such a lid assembly, wherein, the lid assembly includes: a cover lid, venting holes arranged at a middle part of the cover lid; a baking assembly arranged on the cover lid and communicating with the venting hole; an air discharging tube passing through the cover lid; a pressure limiting valve arranged on the air discharging tube; a sealing hood detachably arranged below the cover lid and including a first annular position-limiting protrusion protruding upward, the first annular position-limiting protrusion surrounding the outer side of the venting holes and located at the inner side of the air discharging tube; a first sealing part includes a first sealing lip, a second sealing lip, and a position-limiting part in cooperation with the first annular position-limiting protrusion to fix the first sealing part to the sealing hood. The first sealing lip cooperates in a sealed manner with the outer face of the first annular position-limiting protrusion, and the second sealing lip cooperates in a sealed manner with a lower surface of the cover lid, to separate the air discharging tube from the baking assembly.

An exhaust assembly, an upper cover assembly, and a cooking device. The exhaust assembly includes: an exhaust system can be opened and closed; an exhaust trigger member that is connected to the exhaust system and suitable for triggering the opening of the exhaust system; a reset trigger member that is connected to the exhaust system and suitable for triggering the closing of the exhaust system; and a toggle member adapted to move between an exhaust position and a close position, and when located at the exhaust position, the toggle member actions on the exhaust trigger member and makes the exhaust trigger member trigger the opening of the exhaust system, and when located at the close position, the toggle member actions on the reset trigger member and makes the reset trigger member trigger the closing of the exhaust system.

A device for and method of releasing pressure from a pressure cooker using an arrangement of magnets that influence the opening and closing characteristics of a pressure relieve device used in a pressure cooker. The device configured using magnets which act to repel each other causing the pressure release valve to operating more quickly than valves relying on gravity to open.
