An oven appliance with one or more features for controlling airflow within a cooking chamber of the oven appliance. Further, a method for operating an oven appliance to control airflow within a cooking chamber of the oven appliance. In particular, the oven includes features for and the method includes steps for dynamic control of the speed of a convection fan over an oven cycle to maintain proper airflow within the cooking chamber for cooking performance of the cooking chamber.

A cooking appliance and method may generate one or more audible and/or visual indications to a user of various gas burner states during the operation of a gas burner, including, for example, states that are associated with different types of ignition operations, such as initial ignition operations, programmed re-ignition operations and/or flame loss re-ignition operations and/or states that are associated with ignition operations, normal operating conditions, and/or failure conditions.

A stove controller starts an unattended timer when a cooking process is started. The controller monitors whether motion is detected in the kitchen prior to the unattended timer expiring and resets the unattended timer each time motion is detected. If the unattended timer expires without any motion being detected, the controller disables the heating elements of the stove and starts a return timer. The controller monitors whether motion is detected in the kitchen prior to the return timer expiring. When motion is detected, the controller automatically re-enables the heating elements of the stove so that cooking can continue. If motion is not detected and the return timer expires, the controller locks the stove until a reset procedure is performed. Alerts of the stove activity are sent to external devices over the Internet, and the reset procedure may be performed on the controller or on one of the external devices.

A system for heating and/or cooking food whose upper heating limit is adjustable. An energy setting assembly is provided with the system that includes a knob, a restrictor plate, and a limit pin. The limit pin is selectively inserted into openings formed along multiple locations in the restrictor plate, where the openings follow a generally curved path. The knob rotatably mounts over and is generally coaxial with the restrictor plate. Rotating the knob regulates heat output of the system. Web members are formed on the knob and that project in a radial direction from a receptacle in the knob. The web members come into interfering contact with the limit pin when knob is rotated to a designated orientation, so that strategically locating the limit pin, limits angular movement of the knob to the designated orientation, thereby limiting a maximum energy input to the system.

A knob assembly with a display that displays information such as power level and a timer time, and a cooking apparatus including a knob assembly are provided. The knob assembly may include a knob coupled to an adjustment shaft configured to adjust power level and a knob ring configured to surround a periphery of the knob, configured to be rotatable independent of the knob, and provided with a display. The display may be provided at the knob ring, and information may be displayed on the display so that a user may easily manipulate the knob assembly.

A cooking appliance and method generate an audible and/or visual indication to a user when a user control for a gas burner is in a position within which an igniter is active and a gas valve is supplying sufficient gas flow to the gas burner to support ignition and thereby assist a user in properly positioning the user control during ignition of the burner.

A knob assembly includes a light guide and a control knob that is independently rotatable relative to the light guide. The light guide is positioned at an aperture formed on a surface such that the light guide receives light emitted by a light source positioned below the surface along a vertical direction. The light guide also defines a guide opening, and further includes an opaque and translucent region. The control knob defines a light opening and is rotatably coupled to a stem extending through the guide opening. The control knob is rotatable between a first and second position. In the first position, the light opening is positioned entirely over the opaque region of the light guide along the vertical direction. In the second position, the light opening is positioned entirely over the translucent region of the light guide along the vertical direction. A related cooktop appliance is provided.

Provided is a cooking appliance that includes an oven cavity and an oven door is pivotally coupled adjacent to an entrance leading into the oven cavity, and a method of controlling such a cooking appliance. The oven door includes a substantially opaque region that interferes with external observation of the oven cavity while the door is in the closed orientation, and an electrochromic indicator provided to the opaque region. The electrochromic indicator includes a material with a first appearance that renders the electrochromic indicator substantially indistinguishable from the opaque region in a first operational state, and a second appearance in a second operational state that contrasts with the opaque region to issue a notification related to operation of the cooking appliance.

A knob assembly includes a knob, a light assembly, a light socket, and a receptacle. The light assembly includes a light diffuser, a light source, and a light connector prong. Light from the light source is transmitted through the light diffuser. The light connector prong is electrically connected to the light source to provide power to the light source when the knob is rotated. The light socket includes a socket housing, a light connector aperture wall, an electrical connector aperture wall, and an internal conductor. The light connector prong is mounted within the light connector aperture wall. A power connector prong connectable to a power source is mounted within the electrical connector aperture wall. The connector housing of the receptacle is configured to house the light socket. The light connector prong is inserted into the light connector aperture wall through a first wall of the device.

A knob assembly for a gas valve of a cooking appliance and a method of assembling said knob assembly is provided. The knob assembly can include a knob configured to engage a valve stem of the gas valve and a lock assembly including a locking element and a locking plate. The locking element can include at least one cam element that can be engaged by at least one projection carried by the locking plate. The locking plate can be configured to rotate relative to the locking element between a first position in which the at least one projection engages the at least one cam element and a second position in which the at least one projection is disengaged from the at least one cam element, and wherein in the first position the at least one cam element inhibits actuation of the gas valve by the knob.
