An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

An oven appliance includes a cooking chamber positioned within a cabinet and a heating assembly for selectively heating the cooking chamber. The cooking chamber has two or more separate regions, and a temperature sensing assembly includes a temperature sensor positioned within each region of the cooking chamber. A switching assembly is coupled to the first temperature sensor and the second temperature sensor and is adjustable between a first position that connects the first temperature sensor to a controller and a second position that connects the second temperature sensor to the controller.

A gas burner assembly includes a gas burner and a grate with a plurality of fingers positioned above the gas burner. The plurality of fingers include a sensor finger. The gas burner assembly also includes a temperature sensor mounted to the sensor finger of the plurality of fingers of the grate. The temperature sensor is thermally isolated from the sensor finger.

A system for igniting a grill can include a solenoid valve, a flame rectification sensor, an igniter, and a control circuit connected to the solenoid valve and the flame rectification sensor. The solenoid valve controls flow of gas to the grill's burner and includes a switch that closes when a handle connected to the switch opens the solenoid valve. The control circuit sends current to the solenoid valve when the switch is closed to hold the solenoid valve open. After the switch closes, the igniter is ignited. After ignition, the control circuit monitors the presence of a flame with a flame rectification sensor. If no flame is detected after a certain amount of time, the control circuit stops sending current to the solenoid valve to close the solenoid valve.

A cooktop includes a knob assembly controls a heating part. The knob assembly includes: a knob body disposed at a front surface of a control panel and rotating around a rotation shaft extended in a front-rear direction, a light diffusing part disposed at a rear side of the knob body and diffusing light, and a light source part disposed at a rear side of the light diffusing part and including one or more light sources. The light diffusing part includes a light source corresponding part disposed at a position corresponding to one of the light sources, and a thickness of the light diffusing part along a first straight line that passes from a center of the light diffusing part through the light source corresponding part is greater than a thickness of the light diffusing part along a straight line that does not pass through the light source corresponding part.

A cooking apparatus including a cooking chamber configured to accommodate food, a camera configured to photograph inside of the cooking chamber, a communication interface, a memory configured to store a cooking method, and a processor configured to, based on food being selected, drive the cooking chamber based on a cooking method corresponding to the selected food, control the camera to photograph the food inside the cooking chamber, and control the communication interface to transmit a photographed image of the food to a user terminal device. The processor is configured to, based on a first feedback related to the photographed image being received, provide a plurality of images for selecting additional cooking states for the food to the user terminal device, and based on a second feedback related to the photographed image being received, provide a plurality of menus for analyzing a cause of a cooking state of the food to the user terminal device.

The present disclosure relates to an artificial intelligence (AI) system for simulating functions, such as recognition and determination, of the human brain by using a machine learning algorithm such as deep learning, and an application thereof. Provided are an automatic cooking device and method for selectively emitting light of different wavelength bands to a food material, identifying the food material by obtaining information about the food material, based on reflected light, and controlling a cooking process of the food material.

Food cooking unit composed of gas burners (1), regulation electrovalves (3) of the supplied gas; an infrared sensor (5) focused towards the cooking zone; a thermocouple (6) in thermal contact with the flames and in connection with a safety electrovalve (4) through a relay (10) and an electronic control device (7) connected to said infrared sensor (5), to said at least one regulating electrovalve (3) and the relay (10) and that stores different regulation programs and that regulates the regulating electrovalve (3) and/or interrupts the thermocouple connection with the safety electrovalve in response to the signals obtained from the infrared sensor (5) and/or the thermocouple (6), and issues warnings in response to signals from the thermocouple (6).
