An electric cooker is configured to cook food in a pressurized state and a non-pressurized state of an inner pot, thereby improving the cooking quality and convenience of use. The electric cooker includes a main body having an inner pot configured to accommodate food and a heating unit; a lid coupled to an upper portion of the main body and opened/closed by an opening/closing unit; and a pressure switching selection unit arranged to pass through the lid and configured to switch or maintain opened/closed states to discharge internal steam from the inner pot by interworking with the opening/closing 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.

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.

Disclosed is a pressure cooker having a negative pressure vacuum state, including a body having an accommodating space, a cover, and a control structure. The control structure includes a sealing elastic member, a pressure relief valve, and a stop valve. The accommodating space includes a high pressure state, a micro-positive pressure state, and a negative pressure vacuum state, and when the accommodating space is in the high pressure state, the pressure relief valve is lifted upward by a high pressure thrust, to discharge high pressure gas in the accommodating space, and the stop valve is lifted upward under pressure to limit opening of the cover and is in a sealed state; and when the accommodating space is in the micro-positive pressure state or the negative pressure vacuum state, the pressure relief valve, the stop valve, the body, and the cover each are in the sealed state.

To enable a user to cook both in a pressure state and in a non-pressure state inside the inner pot and thus improve cooking quality and ease of use, the present invention provides an electric cooker including a main body in which an inner pot for accommodating food is installed; a lid coupled to the main body to be opened or closed, in which a passthrough portion is formed; a pressure converter communicating with the passthrough portion, in which a selectively opened/closed state for discharging steam inside the inner pot is maintained; and a pressure-responsive actuators communicating with the passthrough portion and selectively opened/closed depending on a pressure level inside the inner pot in a pressure cooking mode.

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 lid for a pressure cooking pot includes a lower lid module having an edged lid fitted on a pouring edge of the pressure cooking pot, and a seal sealing the lower lid module when fitted on the pouring edge. An upper lid module includes a closure unit movable between a first position in which the upper and lower lid modules are locked to one another and a second position in which the upper module is separable from the lower module. Fixing claws are coupled to the closure unit and engages under the pouring edge of the pressure cooking pot, when the closure unit is in the first position.

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.

The present invention provides a cover assembly for a cooking apparatus configured to seal a gap between an inner pot accommodated in a main body of the cooking apparatus and a top plate of a main body lid of the cooking apparatus, wherein the cover assembly includes: a cover plate; and a packing coupled to and extending along a circumference of the cover plate, wherein the packing includes: a central body; an upper close contact protrusion extending inward from the central body to be inclined upward and configured to make close contact with the top plate; a lower close contact protrusion extending inward from the central body to be inclined downward and configured to make close contact with the inner pot; an upper air groove provided in an upper surface of the central body; and a lower air groove provided in a lower surface of the central body.

A cooking appliance with features for locking a surface heating element of the cooking appliance such that a power level of the heating element cannot be adjusted through unintended inputs by a user of the cooking appliance is provided. A method for operating a cooking appliance with a surface heating element also is provided. More particularly, a method is provided that includes features for locking a surface heating element of the cooking appliance such that a power level of the heating element cannot be adjusted through inadvertent inputs by a user of the cooktop appliance. Further, a method for operating an appliance is provided; the method includes features for locking a functionality of the appliance such that a setting of the functionality cannot be adjusted through unintentional inputs by a user of the appliance.
