The invention relates to a method for boil detection at a heating zone of an induction hob (1), the method comprising the steps of: disabling (S110) a power control mechanism of the induction hob by setting the frequency of the AC-current provided to an induction coil of the induction hob to a fixed value; measuring (S120) values of an electrical parameter provided within the induction hob (1); interpolating (S130) the measured electrical parameter values by gathering a plurality of values of the electrical parameter within a time window and calculating the average value of said gathered plurality of values thereby obtaining interpolated electrical parameter values. calculating (S140) a gradient measure indicative for the differential change of the interpolated electrical parameter values over time; determining (S150) the boil point based on the calculated gradient measure.

A circulating bath (10) including a heater (18) configured to heat a fluid (34) in a reservoir (22). The heater (18) is configured to be operatively connected to a source of power (50) by a control circuit (39) operatively coupled to the heater (18). First and second fluid level sensors (14) (16) are operatively coupled to the control circuit (39), and provide signals indicative of a low fluid condition in the reservoir (22). The control circuit (39) is configured to receive the signals from the fluid level sensors (14) (16), and disconnect the heater (18) from the source of power (50) in response to receiving a signal from either of the first and second fluid level sensors (14), (16) indicative of a low fluid condition.

An electric kettle may include a body configured to form a space in which liquid, such as water may be contained, a handle that protrudes from an outer surface of the body, a heating module provided inside of the body to heat liquid inside of the body, an operation portion provided in the handle to operate so as to control an operation of the heating module, and a main printed circuit board (PCB) provided inside of the handle to control the operation of the heating module according to an operation of the operation portion. The body may have a double wall structure including two walls spaced apart from each other, and an electric wire that connects the main PCB and the heating module may be guided from the handle to the heating module through a space between the two walls.

An electric kettle may include a body made of a metal material and configured to form a space in which fluid, such as water is contained, a heating module provided in the body to heat the space, a handle mounted to protrude from an outer surface of the body, a handle cover made of a metal material and configured to form a protruding upper surface of the handle, and a handle printed circuit board (PCB) provided inside of the handle and including a touch sensor in close contact with a rear surface of the handle cover to sense a touch operation of the handle cover. An operation of the heating module may be controlled by the handle PCB.

In order to heat a bag filled, for example, with a food product to a predeterminable temperature, the entire cassette (1) has been heated in the past. The invention relates to a cassette (1) made of plastic, wherein in each of the cassette shells (2, 3) a receiving recess (10) is formed, in each of which a respective heat-conducting plate (11) is arranged securely in position. A heating element (20) is applied to the heat-conducting plate (11) and the heat-conducting plate (11) is retained in an insulated manner on the respective cassette shell (2, 3) such that a thermal insulating air gap remains between the heat-conducting plate (11) or the heating element (20) and the cassette shell (2, 3).

An infant bottle is provided. The infant bottle comprises an open-top receptacle for receiving liquid, a nipple sealably connectable to the open-top end of the receptacle, a formula compartment disposed adjacent the open-top end of the receptacle, an open-top end of the formula compartment corresponding and fitted within the open-top end of the receptacle, and a formula release mechanism to empty the contents contained in the formula compartment into the receptacle. A removable warming cover substantially covering at least a portion of the outer surface of the receptacle and comprising a sleeve of material for receiving the receptacle, a base comprising a rechargeable battery, and a heating element operatively connected to the battery, is also provided. A method of using the same is also provided.

An actively heated or cooled portable container has a body with a chamber that receives and holds a liquid, and one or more heating or cooling elements in thermal communication with at least a portion of the chamber. An outer surface of the body has one or more electrical contacts. A module is removably coupled to a portion of the body. The module has one or more electrical contacts on an outer surface of the module that contact the one or more electrical contacts on the outer surface of the body, control circuitry, and one or more power storage elements that provide power to the control circuitry and/or the one or more heating or cooling elements. The control circuitry wirelessly communicates with a mobile electronic device to wirelessly transmit information to the mobile electronic device associated with the operation of the module and/or wirelessly receive instructions from a user via the mobile electronic device.

A steam generator has a water container and an upper heating device and a lower heating device, a first temperature detection device covering a temperature detection area including the area covered by the two heating devices, a control device for monitoring and evaluating the first temperature detection device and for controlling the activation state of the two heating devices. A flat first temperature detection device covers the outside of the container, and a second spot-like temperature sensor is located on the water container in a region of an upper border of the upper heating device. Both temperature detection devices are used to activate and deactivate the two heating devices such that at first the lower heating device is activated to start generating steam as fast as possible.

A control circuit, connectable to a domestic power line (L1, L2), includes a logic controller (1), a power supply (2) for the logic controller (1), at least one control switch (3) for an electrical load (4, 5) connected to the logic controller (1), and an electrically actuated deviator (6) connected to the logic controller (1). The deviator (6) is switchable between a machine activation status, where a main power line (7) of the power supply (2) is connected to the domestic power line (L1, L2), and a machine deactivation status, where a secondary power line (8) of the power supply (2) is connected to the domestic power line (L1, L2), having a normally open switch (9) connected to the logic controller (1), and energy storage that maintains power supply to the logic controller (1) for an operating time of the deviator (6) switching.
