A core cooker device is used for cooking food, and has a heating element adapted for insertion into food to be cooked, a temperature control device for controlling power supplied to the heating element, and a power supply for providing power to the temperature control device. The core cooker heating element has a stem portion, and the power supply includes a coaxial cable connector and an interior wire, and includes a BNC connector and an O-ring. The BNC connector is connected to the stem portion, and the coaxial cable connector is secured by threaded engagement with the BNC connector. The interior wire is connected to a heating wire at a junction of the BNC connector and the stem portion.

A liquid heating appliance for placement on an induction hob includes a liquid vessel, a ferromagnetic heating plate mounted within the vessel by a lifting mechanism, and a thermally sensitive actuator. The lifting mechanism is operable to move the ferromagnetic heating plate upwards within the vessel in response to the thermally sensitive actuator detecting that the heating plate exceeds a predefined temperature.

A container adapted to store and heat a liquid, such as water, or other content is presented herein. The container includes a main body including an interior portion and an at least partially open top end. A dual opening top cap is removably connected to the at least partially open top end of the body. Furthermore, a heating assembly is connected to a bottom end of the body. The heating assembly includes an at least partially exposed heating element that is adapted to be in direct contact with the fluid, beverage or other liquid contained within the body. In some embodiments, the heating assembly is adapted to and capable of heating the liquid and/or other contents contained with within the interior portion of the body to a boiling temperature.

A sous-vide circulator cooker includes a casing including a front shell and a rear shell; a wheel control device, a temperature limiting thermostat, a circuit board for controlling switch, a mechanical fan for drawing cold air in and expelling hot air out, a main circuit board configured to activate heating and agitation; a drive source for agitation and testing, a support for heating member, an electric heating member, a fan blade assembly, a lower case section configured to store a quantity of liquid which is configured to be agitate by the fan blade assembly, an inlet device including, a fastening assembly, and an AC power cord for supplying power to electrical components of the circulator cooker.
