Abstract
This invention relates to temperature control of hot beverages served in mugs/cups. It is particularly well suited for ensuring that temperatures of hot drinks can be maintained in an optimum/preferred range for long periods of time. It can also be used for heating and/or temperature control of other food items such as soups and gravy, as well as fluids/suspensions/slurries in various consumer, commercial and industrial applications. The invention achieves this by utilizing one or more compact heating blocks that comprises an electrical energy storage module with electric heating, power receiving and recharging circuits that are encapsulated together to permit total immersion in a hot drink. During use, these are be added to a drink to maintain it at a high temperature in a manner similar to ice-cubes that are used with cold drinks. A separate charger is then used to charge/recharge the heating block(s) in a non-contact manner after each use.
