Abstract

An actively heated mug or travel mug is provided. The mug or travel mug can include a body that receives a liquid therein and a heating system at least partially disposed in the body. The heating system can include one or more heating elements that heat a surface of the receiving portion of the body and one or more energy storage devices. The mug or travel mug can include a wireless power receiver that wirelessly receives power from a power source and control circuitry configured to charge one or more power storage elements and to control the delivery of electricity from the one or more power storage elements to the one or more heating elements. The mug or travel mug also can have one or more sensors that sense a parameter of the liquid or sense a parameter of the heating system and communicates the sensed information to the control circuitry. The control circuitry can turn on, turn off, and/or operate the heating element to actively heat at least a portion of the body to maintain the liquid in a heated state generally at a user selected temperature setting based at least in part on the sensed parameter information. The mug or travel mug can also be paired with a remote device or mobile electronic device to send or receive communications or commands.

Claims

1. An actively heated and cooled mug or travel mug, comprising:

a body having a receiving portion for receiving and holding a liquid; and

a heating and cooling system, comprising

three or more thermoelectric heating and cooling elements electrically isolated from each other and configured to actively heat and cool at least a portion of the receiving portion of the body,

one or more power storage elements,

a wireless power receiver configured to wirelessly receive power from a power source,

control circuitry electrically connected to the wireless power receiver, the control circuitry configured to charge the one or more power storage elements and to control the delivery of electricity from the one or more power storage elements to the heating and cooling elements, and

one or more temperature sensors configured to sense a temperature of the liquid in the receiving portion,

wherein the control circuitry is configured to operate each of the of heating and cooling elements independently of each other to actively decrease the temperature of the liquid if said temperature is greater than a predetermined drinking temperature, and configured to operate the heating and cooling elements to actively increase the temperature of the liquid if said temperature is lower than the predetermined drinking temperature.

2. The mug or travel mug of claim 1, further comprising one or more ultrasound liquid sensors configured to sense when a liquid is poured into the receiving portion via a change in frequency and to communicate said sensed information of liquid presence to the control circuitry, the control circuitry configured to transmit to the user via a user interface information indicative of the volume of liquid in the receiving portion based on said sensed liquid level.

3. The mug or travel mug of claim 1, wherein the control circuitry is configured to automatically shut off power to the heating and cooling elements when a charge level of the one or more power storage elements falls below a predetermined percentage of an amount corresponding to a full charge.

4. The mug or travel mug of claim 1, further comprising a wireless transmitter or receiver and/or transceiver configured to establish a communication connection with a remote electronic device or mobile electronic device.

5. The mug or travel mug of claim 1, wherein the body of the mug or travel mug is water tight and/or dishwasher safe.

6. The mug or travel mug of claim 1, further comprising an orientation sensor configured to sense an orientation of the body, the control circuitry configured to turn off power to the heating and cooling elements and disable said sensors when the body is tilted by more than a predetermined amount from an upright vertical orientation of the body, where an opening of the mug body is at a top end and a base of the body is at a bottom of the mug or travel mug.

7. The mug or travel mug of claim 1, further comprising a water resistant lid removably coupleable to a portion of the body, the water resistant lid selectively removable to allow access to at least the one or more power storage elements.

8. An actively heated and cooled mug or travel mug, comprising:

a body having a receiving portion for receiving and holding a liquid, the body having a vacuum insulated chamber configured to reduce the rate in which heat energy exits the mug or travel mug; and

a heating and cooling system, comprising

three or more heating and cooling elements electrically isolated from each other and configured to actively heat and cool at least a portion of the receiving portion of the body,

one or more power storage elements,

a wireless power receiver configured to wirelessly receive power from a power source, and

control circuitry electrically connected to the wireless power receiver, the control circuitry configured to control charging of the one or more power storage elements and to control the delivery of electricity from the one or more power storage elements to the heating and cooling elements to maintain a temperature of the liquid generally at a predetermined drinking temperature or within a predetermined drinking temperature range, the control circuitry configured to operate the heating and cooling elements independently of each other.

9. The mug or travel mug of claim 8, further comprising one or more sensors configured to sense a parameter of the liquid and communicate said sensed information to the control circuitry.

10. The mug or travel mug of claim 9, wherein the one or more sensors is a liquid sensor configured to sense the presence of liquid in the receiving portion of the body, the control circuitry configured to turn on power to the heating and cooling elements in response to said sensed presence of the liquid.

11. The mug or travel mug of claim 8, further comprising a wireless transmitter or receiver and/or transceiver configured to establish a communication connection with a remote device or mobile electronic device.

12. The mug or travel mug of claim 8, wherein the body of the mug or travel mug is water tight and/or dishwasher safe.

13. The mug or travel mug of claim 8, further comprising an orientation sensor configured to sense an orientation of the body, the control circuitry configured to turn off power to the heating and cooling elements and disable one or more sensors when the body is tilted by more than a predetermined amount from an upright vertical orientation of the body where an opening of the body is at a top end and a base of the body is at a bottom of the mug or travel mug.

14. The mug or travel mug of claim 8, wherein the one or more power storage elements comprise a battery pack removably coupleable to the dishwasher safe body.
