A heating preservation system includes a selected unit, a control unit, a detection unit, and a heating unit. The selected unit is configured to select a preset temperature from amongst a plurality of differing preset temperatures, each preset temperature corresponds to a preset voltage. The control unit is configured to send out the preset voltage according to the selected preset temperature. The detection unit is configured to detect a temperature of fluid and convert the temperature to a detected voltage. The comparison unit is configured to receive the preset voltage and the detected voltage and compare the detected voltage with the preset voltage. The heating unit is configured to heat the fluid when the detected voltage is less than the preset voltage, and stop heating the fluid when the detected voltage is more than the preset voltage. A smart cup using the heating preservation system is further disclosed.

An electric kettle may include a body formed in a cylindrical shape having an open upper surface and an open lower surface, the body defining a space in which fluid, such as water may be contained, an upper body mounted on an upper end of the body and communicating with the open upper surface of the body, a lid seated on the upper body to open and close the open upper surface of the body, a heating module inserted and mounted through the open lower surface of the body to partition an inside of the body vertically and heat fluid inside of the body, and a base on which the lower surface of the body is seated and which transfers power applied from outside to the heating module when the body is seated. The body may include an outer body forming an outer surface and an inner body forming an inner surface. The heating module may be mounted on the inner surface of the inner body.

An actively heated or cooled portable container is provided. The container has a portable body with a receiving portion defined by an inner wall that receives a liquid. A heating and cooling system housed in the portable body has a cooling element in thermal communication with at least a portion of the inner wall to remove heat from the liquid. The heating and cooling system also has a heating element in thermal communication with at least a portion of the inner wall, control circuitry to control the operation of the heating element and one or more power storage elements to provide electrical energy to the heating element and/or control circuitry. The control circuitry controls the heating element to add heat to the liquid in the receiving portion to maintain the temperature of the liquid at a predetermined temperature or increase the temperature of the liquid above said predetermined temperature. Optionally, the control circuitry can calculate a volume of the liquid in the receiving portion of the portable body based on sensed information indicative of a temperature of the liquid in the receiving portion.

A breast milk sterilizing apparatus provided with a nursing bottle holding breast milk, a holder cylinder body of metal having a cylindrical wall portion to which the nursing bottle is inserted, a heater and a heater temperature sensor wound around a periphery of the cylindrical wall portion, a breast milk temperature sensor to measure breast milk temperature on a bottom face of the nursing bottle, and a breast milk temperature controlling portion to control the heater based on a breast milk temperature measured value measured by the breast milk temperature sensor.

A kettle (10) comprising: a hollow body (14) having a bottom wall (16) and a side wall (18) extending upwardly from the bottom wall (16) to a rim (19), with the side wall (18) surrounding a cavity (22) to receive water to be heated, the bottom wall (16) having an inner surface (17) facing the cavity (22), the inner surface (17) having an area; and a heating element (32) in thermal communication with the bottom wall (16) to thereby heat the water, the heating element (32) occupying a horizontal area that is at least 30% of the inner surface area (17).

An electric kettle has a kettle body and a power supply unit that is configured to supply power to the kettle body. The power supply unit has a power supply base, a mounting unit and a first detection part. The power supply base is configured such that the kettle body is placed on top thereof, and has a power supply connection part that is configured to be electrically removably connected to a power receiving connection part. The mounting unit is configured such that a battery pack is removably coupled thereto as an external power source for supplying power to a heating part via the power supply connection part and the power receiving connection part. The first detection part is configured to detect that the power supply unit is on a plane.

A power electronics assembly of a domestic appliance includes a first relay controlling an electrical contact between a first current-carrying conductor and an electric consumer. The assembly further includes a semiconductor switching element that switches the electrical contact between the first current-carrying conductor and the electric consumer and is arranged in parallel with the first relay. A controller is programmed to activate the semiconductor switching element to switch on the electrical consumer before the first relay is closed.

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.
