A method of heating/cooling one or more substrates includes placing the one or more substrates on a rotatable hot-cold plate, wherein each substrate of the one or more substrates is placed on a corresponding sub-plate of a plurality of sub-plates of the rotatable hot-cold plate. The method further includes rotating the one or more substrates, wherein rotating the one or more substrates comprises rotating each substrate of the one or more substrates independently. The method further includes heating or cooling the one or more substrates using a heating-cooling element, wherein rotating the one or more substrates comprises rotating the one or more substrates relative to the heating-cooling element.

Disclosed herein are a surface heater, an electric range having the same, and a manufacturing method thereof. The surface heater includes a substrate including a surface formed of an electrically insulating material, heating element attached to the surface of the substrate by sintering predetermined powder including lanthanide oxide powder, and a power supply unit configured to supply electricity to the heating element. The electric range includes the surface heater. The manufacturing method of the surface heater includes baking the predetermined powder at a baking temperature of 900° C. or lower.

A placeable cooktop utensil includes: a handle for handling the placeable utensil; a controller; a transmitter unit for transmitting signals from the placeable utensil to the cooktop; and at least one input unit having at least one input area integrated in the handle for a user of the placeable utensil to input a user command, the transmitter unit and the at least one input unit being connected in signal communication with the controller, and the cooktop being controllable by the user command. The handle has a gripping portion for gripping and manually moving the placeable utensil and at least one input portion. The at least one input area is in the at least one input portion. At least one sensor for detecting the handle being approached and/or contacted by the user, is in the gripping portion.

Embodiments of the present disclosure generally relate to methods and apparatus for visual lamp failure detection in a processing chamber, such as an RTP chamber. Visual feedback is facilitated through the use of a wide-angle lens positioned to view lamps within the process chamber. The wide-angle lens is positioned within a probe and secured using a spring in order to withstand high temperature processing. A camera coupled to the lens is adapted to capture an image of the lamps within the process chamber. The captured image of the lamps is then compared to a reference image to determine if the lamps are functioning as desired.

An oven appliance, as provided herein, may include a plurality of chamber walls, a bottom heating element, a base panel, and a cooking plate. The plurality of chamber walls may define an oven chamber. The plurality of chamber walls may include a back wall, a top wall, a first side wall, a second side wall, and a bottom wall. The bottom heating element may be mounted above the bottom wall to heat a cooking surface within the oven chamber. The base panel may be disposed over the bottom heating element. The base panel may define an oven vent and a receiving zone spaced apart from the oven vent. The base panel may further define an enclosed region with the bottom wall about the bottom heating element. The cooking plate may be disposed on the base panel within the receiving zone. The cooking plate may define the cooking surface.

Presented is a heating element, and method for producing same, comprised of strip material having a length, width and depth where the strip material is twisted at least once axially relative to its length and bent at least once across its width resulting in a generally flat profile. The twists and bends provide for expansion and contraction of the heating element and thereby provide stress relief during heating and cooling.

A measurement device for determining heating parameters of an oven may generally include a support plate and at least one sensor cup coupled to the support plate. The sensor cup may define a liquid well for receiving a volume of liquid and may include a bottom wall defining a floor of the liquid well. In addition, the measurement device may include a temperature sensor positioned adjacent to the floor of the liquid well such that the temperature sensor is configured to be in fluid contact with at least a portion of the volume of the liquid received within the liquid well. The temperature sensor may be configured to monitor a temperature of the liquid as the liquid is heated and evaporates from the sensor cup.

Provided is an apparatus and method for protecting against unsafe electric current conditions. A protections circuit may be used in a device, such as an electric grill, that has one or more electric loads, such as heating elements. The protection circuit may protect against various failure scenarios, including, without limitation, instances of ground fault, over current, driver failure, and failure of a microprocessor. The microprocessor may further be in wireless communication with a remote device and wirelessly communicate error codes indicative of an error, and receive control signals from the remote device for controlling temperature or turning the grill off. The remote device may also receive operating parameters and create a log of the electric grill's conditions at the time of an error.

A multi-sensored smart cooking apparatus includes a setting module for setting at least one of a cooking time and a cooking temperature, a sensing module comprising at least one of a temperature sensor, a weight sensor, and a water level sensor, a controller coupled to the setting module and the sensing module, a cooking module coupled to the sensing module and the controller, where the controller is configured to adjust at least one of the cooking time and the cooking temperature in response to one or more sensed signals from the sensing module. The multi-sensored smart cooking apparatus is configured to turn off, when a sensed temperature of the cooking module is above a temperature threshold, when a sensed weight on the cooking module is below a weight threshold, or when a sensed water level is below a water level threshold.
