A solid-state radio frequency (SSRF) water heating apparatus is disclosed. In embodiments, the SSRF water heater includes a water tank, SSRF generator array and RF sensors enclosed within an RF-shielded cage. The SSRF array synthesizes RF signals in the microwave range and transmits the RF energy through the water tank, exciting and heating the water molecules without direct contact. The RF sensors at the opposite end of the tank sense residual RF energy not absorbed by the water. Control processors regulate the generation and transmission of the RF energy based on the sensed residual energy. The heated water and/or generated steam is piped to hot water dispensers, beverage makers, or steam ovens.

An actively heated drinkware container includes a vessel with a chamber that receives and holds a volume of liquid. The drinkware container includes a heating module with a first heating element operable to heat one portion of the chamber and a second heating element operable to heat another portion of the chamber, the second heating element spaced from the first heating element. Operation of the first and second heating elements generates a circulation current in the volume of liquid in the chamber that mixes the liquid and diffuses a temperature of the liquid to thereby reduce temperature stratification of the liquid in the chamber and so that a temperature of the liquid throughout the volume of liquid in the chamber is approximately uniform.

A system for detecting a possibility of boiling over and preventing said boiling over, the system comprising a vessel (101) having a lid (102), the lid (102) being characterised in that it is configured: to receive information on an initial level of a vessel content and a current level of the vessel content; and based on a difference between the initial level and the current level as well as the time of a creation of said difference: to instruct, by means of a controller (203), a height actuator (207) of the lid (102) to extend said lid (102) vertically, in order to extend the height of said vessel (101); and to instruct, by means of a controller (203), an aperture actuator (206) to create an aperture in a top of the lid (102) in order to facilitate exchange of heat.

An article of manufacture includes a wall portion having a wall inner surface and a wall outer surface, a base portion having a base inner surface and a base outer surface, at least a portion of the wall portion and the base portion forming a vessel to retain fluid therein, at least part of the base portion configured to receive heat, and a plurality of shaped portions with at least three sides extending above, each shaped portion of the base inner surface including at least three sides and polygonal shaped tops, each of the plurality of shaped portions capable of supplying heat from the sides to fluid adjacent to the sides, the plurality of shaped portions including the polygonal shaped tops to induce creation of a plurality of hexagonal convection cells in contact with a surface of the fluid which increases heat transfer from a heating source to the fluid.

A mobile liquid tank is disclosed that includes an insulated tank body and two heating elements. Also disclosed is a liquid heating system comprising the mobile liquid tank, as well as methods of heating a liquid using the mobile liquid tank.

The present disclosure relates to an apparatus and a method for estimating a state of an object to be heated based on sound which is generated when the object to be heated is heated, and providing the estimated information to other devices in an Internet of Things (IoT) environment through a 5G communication network. The heating apparatus may include a housing having a receiving space therein, a heating member disposed within the housing, a power supplier for supplying power to the heating member, a top plate disposed on the top of the housing to support the object to be heated, a sound sensor disposed on the bottom of the top plate, and a controller for predicting the state of the object to be heated by using a deep neural network model that has been trained through machine learning based on a sound signal received from the sound sensor.

According to an example aspect of the present invention, there is provided a method, kettle and temperature sensor for measuring temperature in a kettle. The method comprises a heatable vessel formed by a bottom (16) and a wall (17) and a mixer tool (3) mounted in the vessel and having a rotation axle (18) in the middle of the vessel, the method comprising providing a temperature sensor, comprising a wireless transmitter (5), a sensor element setup (11, 12, 13, 14) connected to the wireless transmitter (5), comprising at least two temperature sensor elements, a sensor body (10) for the sensor element setup (11, 12, 13, 14), mountable to the mixing tool (3) so that at least the temperature sensor elements (11, 12, 13) are set radially at a distance from the rotation axle (18) of the mixer tool (3) and at different distances from the bottom (16) of the vessel and measuring the temperature within the vessel at least at two points set radially at a distance from the rotation axle of the mixer tool and at different distances from the bottom (16) of the vessel.

An electric kettle includes a power supply base, and a kettle main body to be removably mounted on the power supply base. The kettle main body has: a container having a bottomed cylindrical shape that contains a liquid; a nozzle provided in a lower part of a side surface of the container; and a valve mechanism that opens and closes a flow channel for the liquid from the container to the nozzle.
