A pressure cooker comprises a main body, a lid assembly, and an open-prevention assembly disposed on the lid assembly. The main body comprises a cooker rim and a cooker tooth extending therefrom, the open-prevention assembly comprises an open-prevention sliding block and a float device disposed on the lid assembly. With no pressure in the cooking chamber, rotating the lid will cause sliding movements of the open-prevention sliding block. With pressure in the cooking chamber, the float device will rise to prevent the open-prevention sliding block from sliding, thereby preventing the rotation of the lid. The open-prevention assembly comprises a locking sliding block coupled to the open-prevention sliding block. When a forced opening of the lid causes a deformation of the open-prevention sliding block, the locking sliding block lockingly engages the cooker tooth to prevent lid rotation, thereby ensuring safe use of the cooker.

An induction heating cooker includes: a lid including at least one electronic device and a first terminal electrically connected to the electronic device; a main body having a upper surface that defines an opening, in which the main body includes a second terminal configured to connect to the first terminal based on rotation of the lid with respect to the upper surface of the main body; an internal pot configured to be accommodated in the main body; a coil part configured to heat the internal pot based on (i) external power being supplied to the coil part or (ii) electric currents being induced by a working coil of an induction heating apparatus; and a power supplying circuit configured to supply power to the electronic device in the lid through the first and second terminals.

An electric cooker is configured to cook in a pressure state and a non-pressure state of an inner pot, thereby improving the cooking quality and convenience of use. The electric cooker includes a main body provided, at an upper end thereof, with a flange portion and configured to accommodate an inner pot therein; a lid coupled to an upper portion of the main body and opened/closed by an opening/closing unit; a locking ring rotated by interworking with the opening/closing unit, selectively engaged with the flange portion, and provided, at an upper surface thereof, with a marker configured to indicate a rotational direction; a pressure switching unit arranged to pass through the lid and opened or closed by interworking with the opening/closing unit to discharge internal steam from the inner pot; a sensor unit configured to sense the marker when the locking ring is rotated to be locked or unlocked; and a control unit that activates power supply to the main body when a sensing signal is received from the sensor unit.

An electric cooker is configured to cook in a pressure state and a non-pressure state of an inner pot, thereby improving the cooking quality and convenience of use. The electric cooker includes a main body configured to accommodate an inner pot; a lid coupled to an upper portion of the main body and having a handle portion provided at one side of an upper portion of the lid to interwork with an inner pot locking unit configured to lock the inner pot; a pressure switching unit arranged to pass through the lid and configured to switch or maintain an opened or closed state to discharge internal steam from the inner pot according to a rotation of the handle portion; and a pressure-responsive operating unit which is selectively opened or closed according to a pressure inside the inner pot in a pressure cooking mode in which the pressure switching unit is closed.

The present disclosure is directed to a lid for a cooking appliance with a protective shield. One form of a lid comprises a shield; a pressure release valve positioned on a first side of the shield, configured to move between an open position and a closed position; a switch positioned on a second side of the shield; a slider in communication with the switch; and a lever, where a first end of the lever is in communication with the pressure relief valve and a second end of the lever is in communication with the slider. The switch is configured to, when activated, move the slider such that the slider depresses the second end of the lever, thereby raising the first end of the lever and moving the pressure release valve from the closed position to the open position.

A cooking device according to an exemplary embodiment of the present disclosure includes: a main body in which an inner pot is accommodated; a top plate provided in a lid cover coupled to the main body; a locking slide coupled on the top plate so as to be linearly movable in a first direction; and a locking structure including an engagement protrusion which is configured to be engaged with a flange portion of the inner pot. The locking structure is configured to be linearly moved, depending on a position of the locking slide performing a linear movement in the first direction, between a locking position where the engagement protrusion is positioned so as to overlap with the flange portion of the inner pot in a vertical direction and an unlocking position spaced apart from the locking position toward an outside of the top plate.

A pressure cooker system having a cooking vessel, a removable pot, and a lid securable to the vessel. The lid is rotatable from a locked and fully-secured position to an unlocked and hinged position. The pressure cooker system also includes a plurality of locking flanges on an upper periphery of the open cooking vessel which correspond and interlock with a plurality of locking flanges on an interior periphery of the lid. A pressure indicator cooperates with a locking mechanism to prevent opening of the lid when the contents are under pressure. As an added safety feature, a pressure release gap located on one of the interlocking flanges prevents pressure build-up when the lid is not in the closed and locked position.

The invention relates to a food-cooking utensil including: locking/unlocking means; and a control member (6) for controlling the movement of said locking/unlocking means; the control member (6) and the locking/unlocking means co-operating so that the position of the locking/unlocking means varies as a function of the position of the control member (6) in a first relationship while the control member (6) is being moved from its locking position towards its unlocking position, and so that the position of the locking/unlocking means varies as a function of the position of the control member (6) in a second relationship while the control member (6) is being moved from its unlocking position towards its locking position. Food pressure cooking devices.

A pot lid assembly includes a lid body, a plurality of lock members arranged in a circumferential direction of the lid body and each being movable between a lock position at which the lock member is close to a middle of the lid body and an unlock position at which the lock member is far away from the middle of the lid body, a connector extending in the circumferential direction of the lid body and connected to the plurality of lock members, and a drive device connected to the connector. The drive device is configured to drive the connector deform to drive the plurality of lock member

An onboard multi-functional thermal-insulation and explosion-proof pressure steamer, relating to the technical field of heating cooking appliances, and in particular, to the field of cooking appliances mounted on a travelling apparatus, comprising a steamer body and a steamer outer cover covering the top of the steamer body, a steam pot being provided in the steamer body. The steam pot is provided in the steamer body to seal a steam container in the steam pot, and the steam pot is heated by means of the onboard heat energy, heat exchange is performed by means of a heat exchange device to generate high-temperature steam to heat the food material in the steam pot of the steam or to heat the water in a water tank.
