A coupler for use in a liquid heater includes a male connector and a female socket connector. The male connector includes a connecting wall and an annular cylindrical wall formed around the connecting wall. The female socket connector comprises an end wall joined with the connecting wall of the male connector and a peripheral wall formed around the end wall and arranged perpendicularly to the end wall. The surface of the end wall joined with the connecting wall is gradually lowered from the center towards the periphery and is convex-hull shaped. The peripheral wall includes arced sections and gapped sections connected between two arced sections. When the male connector is coupled with the female socket connector, this allows the arced sections to be coupled with the annular cylindrical wall and forms no coupling between the gapped sections and the annular cylindrical wall.

A smart kettle is disclosed. The smart kettle includes a body that is configured to increase in temperature in response to a magnetic field. The smart kettle further includes a temperature sensor that is located on a bottom of the body and that is configured to measure a temperature of the bottom of the body. The smart kettle further includes a controller that is configured to adjust a strength of the magnetic field based on the temperature measured by the temperature sensor by outputting a control signal.

An electric heating pot including a body unit and a heating unit configured to provide heat to the body unit. The body unit includes an accommodation space configured to accommodate liquid, the heating unit includes a housing formed such that electrolyzed water is disposed therein, and an electrode portion that is disposed in the housing, formed such that at least one region thereof is in contact with the electrolyzed water in the housing, and includes a plurality of electrodes.

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.

Collapsible heatable liquid containers having three non-inverting tiers and two inverting tiers interposed between the non-inverting tiers. The non-inverting tiers are typically formed of a stiff (i.e., stiff or rigid) material that is different from the material of the inverting tiers, which is typically a resilient polymer such as a thermoplastic elastomer or silicone. The bottom non-inverting tier is typically formed of a material suitable for inductive, contact, and flame heating, such as stainless steel. The container may be a liquid vessel suitable for drinking, beverage heating and serving, or cooking, such as a drinking bottle or kettle. A bottle may include an attached cap that engages the top tier to close the bottle, and a kettle may include a pour spout connected to the middle or top tier.

A beverage apparatus, system and methods for use are provided. The apparatus includes a pressure vessel configured to receive a flexible bag for containing a beverage. A pressure release valve is connected to the bag, and a pressure source connected to the pressure vessel. A temperature adjustment device is also provided to adjust temperature within the pressure vessel. A controller controls the temperature adjustment device and the pressure source to achieve a desired temperature and pressure within the pressure vessel according to a current mode of the apparatus, where the current mode is selected from a plurality of modes.

A rice cooker assembly uses machine learning models to identify and classify different types of food stored. The rice cooker has a chamber including different compartments for storing different types of food. A camera is positioned to view an interior of the chamber. The camera captures images of the contents of the chamber. From the images, the machine learning model classifies the different types of food stored. The rice cooker determines a mixture of different types of food based on nutrition value and/or taste. The rice cooker creates the mixture and controls the cooking process accordingly. The one or more machine learning models may be resident in the rice cooker or it may be accessed via a network.

In the present invention, provided is a monitoring device (10) including an operating-state-change information acquisition unit (11) that acquires operating-state-change information indicating a time-series change in operating states of an electrical device, the device being capable of assuming multiple types of operating states, a standard transition pattern storage unit (12) that stores standard transition pattern information indicating a pattern of transition between operating states generated in a normal electrical device, and a monitoring unit (13) that determines whether or not the electrical device is normal using the operating-state-change information and the standard transition pattern information.
