An electro-mechanical energy regulator for controlling an application of power supplied to a heating element of a cooking appliance that provides simmer operation is provided. The temperature and/or mode of operation is made via a user interface knob that is coupled to a switching control cam. This cam has an outer profile configured to drive a switching element via a power switch cam follower to close two power line contacts to power a heater. The heater drives a bimetal element whose deflection forces a temperature control switching element to close to enable power to flow to the heating element. The regulator also includes a cooking mode selector operable to open and close a pair of electrical contacts coupled in series with the heating element, and a diode coupled in parallel with the pair of electrical contacts.

The invention relates to a method for operating a heating element (210), in particular in a food processor (1) for the at least partially automatic preparation of foodstuffs, wherein the following steps are performed: a) detecting an electrical resistance of the heating element (210) such that at least one resistance value is determined, b) performing a heating operation on the heating element (210) based on the at least one determined resistance value to perform the heating operation depending on a temperature of the heating element (210).

A heating circuit includes: an inverter circuit, a heating element, a detection element, a first power supply and a second power supply. The first power supply, the heating element and the inverter circuit form a first loop; the second power supply, the detection element and the heating element form a second loop; the first power supply supplies power to the heating element by means of the first loop, and the heating element generates heat on the basis of the power supply of the first power supply; and the second power supply supplies power to the heating element and the detection element by means of the second loop.

An electrical appliance comprising a heating element, the heating element including a heating wire, the heating wire encased within an iron shell, the iron shell having an exterior surface, and a first coating layer disposed on the exterior surface of the shell, wherein the first coating layer is stainless steel. The appliance also includes a power supply. The power supply includes a heating element, a temperature sensor to sense the temperature of the appliance, and a temperature controller in communication with the temperature sensor to maintain the appliance within a desired temperature range. The power supply also includes at least one electrical contact rod operatively engaged with the appliance to supply electrical power to the heating element, and at least one contact receptacle adapted to accept the at least one electrical contact rod. The at least one contact receptacle has a length proportional to the electrical power supplied to the appliance to prevent overheating of the power supply.

A cooking grill utilizes at least one resistive heating element below a cooking grate and radiating heat to the cooking grate when a voltage is applied thereto. A first power source provides an alternating current, and a second power source provides a direct current. First and second power sources provide voltage to the at least one resistive heating element individually or simultaneously.

An induction heating device includes a case, working coils, a cover plate, an input interface, a first control module configured to detect one or more of the working coils at a position of an object seated on the cover plate, a second control module configured to receive information on the position of the object and control the input interface to display an image of a heating zone, and light emitting elements disposed below a periphery of each of the plurality of working coils. The second control module is configured to analyze an arrangement form of the one or more of the working coils based on the information on the position of the object, and control driving of at least one of the light emitting elements based on a result of analyzing the arrangement form.

A range has burner coil elements which have temperature switches as a portion of the replaceable coils. Upon reaching a predetermined temperatures, the switch opens and power through the burner element is secured. The burner elements are preferably open coil units. Lowering the temperature in a cooking utensil below common ignition temperatures while still allowing boiling is an objective of many embodiments.

A kitchen appliance is disclosed for cooking a meat product. The kitchen appliance includes a heating element adapted to heat a medium for transferring heat to the meat product, a sensor for detecting loss of water from a contact surface of the meat product with the medium, and a controller conductively coupled to the sensor. The controller processes a sensor signal produced by the sensor, and generates a control signal indicative of the meat product reaching a defined cooking state in response to the processed sensor signal being indicative of a loss of water associated with the desired cooking state from the contact surface of the meat product.

A cooking appliance having a cooktop that is regulated by a fire prevention module is provided. In addition to its fire prevention and safety features, the fire prevention module includes a communication module that enables communication between the cooktop appliance and a remote device, such as a smartphone or tablet computer. Using this communication link, the fire prevention module can be used to expand the ability of a user to monitor and/or control operation of the cooktop appliance from a remote location. For example, using a software application on their smartphone, a user may monitor the temperature of a cooking utensil and initiate a particular cooking profile, or be notified when an unsafe cooking condition might be present and that the cooktop unit has been automatically deactivated to remedy the situation.
