Heated or cooled drinkware
A container with active temperature control is provided. The container has a body with a chamber that receives a liquid. A temperature control system housed in the portable body has one or more heating element in thermal communication with at least a portion of the chamber to heat the liquid. Control circuitry controls the operation of the one or more heating elements and one or more power storage elements to provide electrical energy to the one or more heating element and/or control circuitry. The control circuitry controls the one or more heating elements 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. The container can have a cooling element (e.g., a phase change material) that can remove heat from the liquid poured into the chamber.
1. A beverage container with active temperature control, comprising:
a body having a chamber configured to receive and hold a liquid; and
a temperature control system, comprising
one or more heating elements in thermal communication with at least a portion of the chamber,
circuitry configured to control an operation of the one or more heating elements; and
one or more sensors configured to sense a temperature of the liquid and communicate sensed temperature information to the circuitry,
wherein when the sensed temperature of the liquid is greater than a predetermined temperature setpoint, the circuitry is operable to turn off or maintain in an off state power to the one or more heating elements such that the temperature of the liquid drops toward the predetermined temperature setpoint, the circuitry configured to turn on power to the one or more heating elements to add an amount of heat to the liquid while the sensed temperature of the liquid is above the predetermined temperature setpoint and before the sensed temperature of the liquid reaches the predetermined temperature setpoint.
2. The container of claim 1 , further comprising one or more power storage elements configured to power one or both of the circuitry and the one or more heating elements.
3. The container of claim 1 , wherein the predetermined temperature setpoint is a user selected temperature.
4. The container of claim 1 , wherein the predetermined temperature setpoint is a previously selected temperature stored in a memory of the container.
5. The container of claim 1 , wherein the circuitry is configured to wirelessly communicate with a remote electronic device to one or both of wirelessly transmit information to the remote electronic device and wirelessly receive information from remote electronic device.
6. The container of claim 1 , wherein the one or more heating elements comprise a heater coil, the circuitry configured to switch power to the heater coil on and off such that an inductance of the heater coil limits a current delivered to the heater coil, thereby inhibiting a temperature of the heater coil from increasing above a target temperature.
7. A beverage container with active temperature control, comprising:
a body having a chamber configured to receive and hold a liquid; and
a temperature control system, comprising
one or more cooling elements operable to passively cool at least a portion of the chamber to cool the liquid disposed in the chamber,
one or more heating elements in thermal communication with at least a portion of the chamber,
circuitry configured to control an operation of the one or more heating elements, and
one or more sensors configured to sense a temperature of the liquid and communicate sensed temperature information to the circuitry,
wherein said one or more cooling elements remove heat from the liquid disposed in the chamber that has a temperature above a predetermined temperature setpoint to lower the temperature of the liquid toward the predetermined temperature setpoint, and wherein when the sensed temperature of the liquid is greater than the predetermined temperature setpoint, the circuitry is configured to turn off or maintain in an off state power to the one or more heating elements such that the temperature of the liquid drops toward the predetermined temperature setpoint, the circuitry configured to turn on power to the one or more heating elements to add an amount of heat to the liquid while the sensed temperature of the liquid is above the predetermined temperature setpoint and before the sensed temperature of the liquid reaches the predetermined temperature setpoint.
8. The container of claim 7 , further comprising one or more power storage elements configured to provide electrical energy to one or both of the circuitry and one or more heating elements.
9. The container of claim 7 , wherein the predetermined temperature setpoint is a user selected temperature.
10. The container of claim 7 , wherein the predetermined temperature setpoint is a previously selected temperature stored in a memory of the container.
11. The container of claim 7 , wherein the circuitry is configured to wirelessly communicate with a remote electronic device to one or both of wirelessly transmit information to the remote electronic device and wirelessly receive information from remote electronic device.
12. The container of claim 7 , wherein the one or more heating elements comprise a heater coil, the circuitry configured to switch power to the heater coil on and off such that an inductance of the heater coil limits a current delivered to the heater coil, thereby inhibiting a temperature of the heater coil from increasing above a maximum target temperature.
13. The container of claim 7 , wherein the one or more cooling elements comprises a phase change material in thermal communication with the chamber.
