An electric heater includes a substrate and an inner plane heating element formed on one surface of the substrate. The inner plane heating element includes an inner pattern portion connecting a start point with an end point. The inner pattern portion includes a first track, a second track located outside the first track and spaced part from the first track, a first bridge connecting the first track with one end of the second track, a third track located outside the second track and spaced apart from the second track, and a second bridge connecting the other end of the second track with the third track. A first gap G1 between the first and second tracks is shorter than a second gap G2 between the second and third tracks along a virtual line crossing the first, second and third tracks and closer to the first bridge than the second bridge.

A cooking apparatus is disclosed, which comprises a first housing provided with an inverter for induction heating; and a second housing including a working coil to which a current supplied from the inverter is transferred, heated as a container for receiving cooking food is arranged thereon, wherein the first housing and the second housing constitute spaces detached from each other.

Disclosed are a split-type cooking appliance and a control method therefor. The control method includes acquiring state information of an identification device after a base is powered on; if the state information is a first state, forbidding the base from operating in an induction cooker operation mode and allowing the base to operate in an electric cooker operation mode; if the state information of the identification device is a second state, determining whether a wireless transmission coil circuit detects a feedback signal; if so, forbidding the base from operating in the induction cooker operation mode and allowing the base to operate in the electric cooker operation mode; and if not, allowing the base to operate in the induction cooker operation mode, and forbidding the base from operating in the electric cooker operation mode.

A cooking unit includes a cooktop, a hood assembly, a duct assembly, and a fan. The cooktop defines a slot at least partially extending along a peripheral edge of the cooktop. The hood assembly includes a hood support extending upward from the cooktop and a hood coupled to the hood support. The hood support defines a conduit. The hood defines an intake and a hood chamber connecting the intake to the conduit of the hood support. The duct assembly includes ducting extending beneath the cooktop. The ducting connects the conduit to the slot. The fan is positioned to drive air into the intake, through the hood chamber, through the conduit, through the ducting, and out of the slot. At least a portion of the air exiting the slot returns to the intake such that an air curtain is generated between the slot and the intake.

A temperature controller assembly is configured to heat and cool liquid within a container. The temperature control assembly has a printed circuit board electrically coupled to a battery, a heat exchanger, and a control switch. A container is mechanically coupled to the heat exchanger and has a volume less than 30 ml. The battery has a battery capacity of 18.5A-h such that when connected to a 3.7 V output to the heat exchanger the battery provides approximately 60-80 watt-hours of energy to the heat exchanger to heat or cool the liquid in the container.

An electric heater includes a substrate; and a plane heating element disposed on one surface of the substrate, in which the plane heating element includes a pattern portion including a start point and an end point; and an electrode portion connected to the start point and the end point of the pattern portion, and a thickness of the electrode portion is thicker than a thickness of the pattern portion.

An electronic stove incorporates a cylindrical outer shell and a concentric copper heater core. A foil heater surrounds the copper heater core and a heater control PCB carried in the outer shell is connected to the foil heater. A battery assembly has a cylindrical second outer shell carrying a battery pack. A power controller carried in the second outer shell is connected to the battery pack. A connector carriage is engaged between the battery assembly and cylindrical outer shell, extending through the shell of the battery assembly and received in the cylindrical outer shell aligned proximate a lower surface of the first outer shell whereby the lower surfaces of the first outer shell and the second outer shell are in planar alignment. A first contact set of a connector is connected to the heater control PCB. A second contact is connected to the power controller.

There is provided an apparatus for heating a pot of food or beverage, the apparatus comprising at least one receptacle (20), each receptacle for temporarily receiving a pot of food or beverage to be heated. Each receptacle comprises a base (22), sidewalls (24), and an opening opposite from the base (22) for receiving the pot; a heater element (43) mounted to the sidewalls; a temperature sensor (45) mounted to the base; a pot sensor (40, 41) for detecting whether or not a pot is present in the receptacle; and a controller connected to the heater element, temperature sensor, and pot sensor. The controller is configured to control the heater element in response to the pot sensor and temperature sensor.

A temperature regulation device for positioning in a well of food service equipment, the temperature regulation device including a housing and a support coupled to the housing. The housing includes a top surface and a bottom surface and the support includes a connector having a connector axis, an outer surface, and an inner surface. The support is rotatable about the connector axis between an extended position and a retracted position. In the extended position of the support, the housing is positioned in a first position relative to the well, and in the retracted position of the support, the housing is positioned in a second position relative to the well.

Temperature regulation devices for heating food are disclosed. The temperature regulation device is configured to heat food held in a food pan positioned in a well of food service equipment. The temperature regulation device includes a module or housing and heating element, and is configurable in a variety of positions, orientations, locations, or configurations relative to the well and the food pans to accommodate a variety of sizes and configurations of food pans.
