A cooking appliance capable of preventing a user's unintended rotation of a knob assembly includes: a main body including a control panel; a valve positioned inside the main body, and including a valve shaft being pushable and rotatable; and a knob assembly including an inner knob coupled with the valve shaft, and an outer knob being movable with respect to the inner knob in a first direction in which the outer knob approaches the inner knob, wherein, when the outer knob moves by a first push distance in the first direction, the valve shaft and the inner knob are prevented from rotating.

A cooking device including a frame that defines a cooking chamber, a burner cover provided in the frame to form a combustion chamber and includes an opening for flowing air, a burner provided inside the combustion chamber, and a barrier member provided between the burner cover and the frame in order to prevent heat of air discharged from the combustion chamber from being delivered to the frame.

A system for controlling an appliance having a plurality of burners operated by a plurality of digital gas valves includes a plurality of control selectors that are configurably assigned to a specified burner or burners.

A convection cooking oven includes a cooking cavity for receiving food product to be cooked, a door movable between an open condition and a closed condition relative to the cooking cavity and a heater for generating heat. A fan system is provided for moving heated air within the cooking cavity, the fan system operable in both a first mode in which air is moved at a first rate, and a second mode in which either (i) air is moved at a second rate, which is lower than the first rate, or (ii) air is not moved by the fan system. A fan system override control is configured such that, when the fan system is operating in the first mode, the fan system is automatically switched to operate in the second mode based upon occurrence of a first predefined oven condition.

A switch assembly for controlling the ignition of gas burners of a cooking appliance having one or more gas valves. The switch assembly includes at least one first support member, operably couplable to a first gas valve, a spring biased ignition switch operably mountable to the at least one first support member, and an actuating member, having a longitudinal axis and operably couplable to at least the first gas valve between the at least one first support member and at least a control knob of at least the first gas valve. The actuating member is adapted to move between a first position, actuatingly engaged with the ignition switch, and a second position, actuatingly disengaged from the ignition switch, wherein the actuating member is moved towards the first position by at least the control knob, and back towards the second position by the spring biased ignition switch.

Systems and methods for radiative heat transfer are disclosed. In an exemplary embodiment, an infrared heater comprises infrared heating elements and a controller. The infrared heating elements correspond to respective heating zones. The controller causes the infrared heating elements to turn on at different time in succession such that respective heating zones are radiatively heated at different times. In some instances, the respective heating zones correspond to different heating zones of a user, and the user feels a heating wave effect as the infrared heating elements are turned on and off at different times.

A cooking appliance includes, a gas cooking element; an electromechanical valve fluidly coupled with the gas cooking element to regulate a flow of gas to the cooking element; a manually-actuated user control movable over a range of positions; and a controller coupled to the user control and the electromechanical valve, the controller configured to determine a position of the manually-actuated user control within the range of positions and to control the electromechanical valve based at least in part upon the determined position to provide a controlled flow curve for the gas cooking element over the range of positions of the user control.

A gas cooktop includes one or more gas burners on a top panel. A high output gas burner is also positioned on the top panel. The high output gas burner is separate from each of the one or more gas burners. The high output gas burner has a maximum heat output greater than each of the one or more gas burners. An electronic control valve is coupled to a supply line of the high output gas burner. The electronic control valve is operable to adjust a flow rate of fuel through the supply line of the high output gas burner. A controller is in communication with the electronic control valve and the one or more control valves. The controller is configured for throttling the maximum heat output of the high output gas burner with the electronic control valve.

A stove knob capable of automatically shutting down a stove in cooperation with heat includes a knob body, an adapter module and a steering joint. The adapter module and the steering joint are selected to be individually or mutually pivoted and then installed between the knob body and the ignition shaft of the stove, and the knob body can be installed to an automatic thermal shutdown machine to fit the use of various different stoves and achieve the effect of expanding the scope of use. The knob body, the adapter and the steering joint can pivotally combined by different orientations and pivotally connected to an ignition shaft of the stove in a predetermined direction, so that a rotary handle of the knob body can be aligned with the best direction and angle towards a user to provide smooth and convenient operations.

A system for controlling an appliance having a plurality of burners operated by a plurality of digital gas valves includes a plurality of control selectors that are configurably assigned to a specified burner or burners.
