An induction range apparatus includes a controller determine whether the container is disposed on the working coil, and the container disposed on the working coil is heated through induction heating, in a container sensing mode, and configured to output a block signal so that induction power outputted from an inverter driver is prevented from being input into a first detector, in an induction heating mode; and a blocking part outputting the induction power input from the inverter driver to the working coil or preventing the induction power input from the inverter driver from being input into the first detector or outputting the sensing signal to the working coil, on the basis of any two or less of the input of the induction power from the inverter driver, the input of the unblock signal from the controller, and the input of the block signal from the controller.

A cooking appliance device includes a control and/or regulating unit provided to repetitively control a first induction target with a first heating current frequency in a periodic continuous heating operating state, which is allocated an operating period, to supply the first induction target with energy, and to operate the first induction target in a switched-on interval of the operating period with a heating power. The control and/or regulating unit is provided to select in the continuous heating operating state a sum of all switched-on intervals of the operating period as a multiple of a reciprocal value of the first heating current frequency.

A cooking appliance device includes a control and/or regulating unit which is provided such that in a periodic continuous heating operation state, which is allocated at least one operating period, an induction target is repetitively controlled, supplied with energy, and operated in a switched-on interval of the operating period with a heating power, and that in the continuous heating operating state a heating current frequency for the induction target in the switched-on interval of the operating period is varied.

In the interests of improved temperature detection and temperature control of a cooking appliance on a hob by means of an induction coil, the cooking appliance has specific and individual identification. This can be contained in an NFC tag, by way of identification means. This identification can be read out on a hob, either by means of the hob itself or by means of a mobile telephone, and transferred to a database in an Internet cloud storage facility. From the latter, specific characteristics for this cooking appliance can be downloaded and employed for a temperature-controlled heating of the cooking appliance.

A cooktop appliance includes a cooking surface configured for receipt of a cooking utensil and an induction heating element operable to inductively heat a load with a magnetic field. The induction heating element includes a coil. The cooktop appliance also includes a sensor. The sensor is operable to detect a location and an efficiency of the cooking utensil. The sensor may be positioned between the coil of the induction heating element and the cooking surface and/or may include a plurality of semi-circular loops spaced apart around a circumference of the coil.

An induction cooktop and a control method for the induction cooktop, the induction cooktop includes: a processing module, a power supply module and a heating module; the power supply module is configured to supply power to the heating module. The heating module includes: a heating circuit configured to heat a pot and a detection circuit connected to the heating circuit. The processing module is configured to acquire a parameter value of a signal collection point of the detection circuit, determine, according to the parameter value, whether the pot is placed on the heating module, and control the heating circuit to heat the pot if it is determined that the pot is placed on the heating module, so as to provide a high heating efficiency.

An output control device includes an output component, a first switch and a second switch. The output component includes a first output coil used for controlling, when the first circuit is turned on and the second circuit is not turned on, the first output coil to enter a heating working state, and controlling, when the first circuit is not turned on and the second circuit is turned on, the first output coil to enter a power transmission working state. The first switch is located in the first circuit and used for turning on the first circuit when being closed. The second switch is located in the second circuit and used for turning on the second circuit when being closed.

According to an embodiment, an electric range includes a core frame. The core frame includes a withdrawal portion on a top surface thereof, formed by removing a portion of a guide rail.
