Abstract

An electronic drinking mug includes a mug having an outer surface, a heating element in thermal communication with the mug for heating a liquid disposed in the mug, and a temperature sensor in communication with the heating element. The mug has a controller in communication with the heating element for selectively activating and deactivating the heating element for heating the liquid in the mug to a desired temperature, and a user interface attached to the outer surface of the mug and being in communication with the controller for establishing the desired temperature of the liquid.

Claims

1. An electronic drinking mug comprising:

a mug having an outer surface;

a heating element in thermal communication with said mug for heating a liquid disposed in said mug;

a temperature sensor in communication with said heating element;

a controller in communication with said heating element for selectively activating and deactivating said heating element for heating said liquid in said mug to a desired temperature; and

a user interface attached to the outer surface of said mug and being in communication with said controller for establishing the desired temperature of said liquid.

2. The electronic drinking mug as claimed in claim 1, wherein said controller receives temperature signals from said temperature sensor and deactivates said heating element when the monitored temperature of said liquid is greater than or equal to the desired temperature of said liquid.

3. The electronic drinking mug as claimed in claim 1, wherein said mug has an upper end and a lower end and wherein said user interface is located closer to the upper end of said mug than the lower end of said mug.

4. The electronic drinking mug as claimed in claim 1, wherein said user interface includes a visual display for displaying the monitored temperature or the desired temperature of said liquid.

5. The electronic drinking mug as claimed in claim 4, wherein said visual display includes a liquid crystal display (LCD).

6. The electronic drinking mug as claimed in claim 1, wherein said user interface includes a LED panel having a series of light emitting diodes, each said light emitting diode being associated with liquid temperature levels selected from the group consisting of room temperature, lukewarm, hot, and very hot.

7. The electronic drinking mug as claimed in claim 1, further comprising a thermostat in communication with said heating element for regulating a temperature of said heating element.

8. The electronic drinking mug as claimed in claim 1, further comprising a sound generating element in signal receiving relation with said controller for selectively generating an audible sound.

9. The electronic drinking mug as claimed in claim 1, wherein said controller includes a logic subroutine that deactivates said heating element when the monitored temperature is greater than or equal to said desired temperature and reactivates said heating element when the monitored temperature falls at least 2°

F. below the desired temperature.

10. The electronic drinking mug as claimed in claim 1, further comprising an electrical connector accessible at the outer surface of said mug for providing electrical power to said controller and said heating element.

11. The electronic drinking mug as claimed in claim 1, wherein said mug includes an outer mug, a removable inner mug insertable in said outer mug, and said heating element disposed between said outer and inner mugs.

13. The electronic drinking mug as claimed in claim 11, wherein the lower end of said mug is insertible into a cup holder so that said user interface is visible and accessible above the cup holder.

12. An electronic drinking mug comprising:

said drinking mug including an outer mug and an inner mug insertable into said outer mug, said mug having an upper end and a lower end;

a heating element in communication with said inner mug for heating a liquid contained in said inner mug;

a temperature sensor in communication with said inner mug for monitoring a temperature of said liquid;

a controller in communication with said heating element and said temperature sensor;

a user interface attached to an exterior surface of said outer mug and being in communication with said controller for establishing a desired temperature for said liquid, wherein said user interface is located closer to the upper end of said mug than the lower end of said mug.

14. The electronic drinking mug as claimed in claim 12, wherein said controller selectively activates and deactivates said heating element so as to heat said liquid in said inner mug to said desired temperature and wherein said controller is adapted to receive temperature signals from said temperature sensor and deactivate said heating element when the monitored temperature of said liquid is greater than or equal to said desired temperature of said liquid.

15. The electronic drinking mug as claimed in claim 12, wherein said outer mug includes a recess and said user interface is secured to said recess.

16. The electronic drinking mug as claimed in claim 12, wherein said outer mug includes a recess and said controller is secured to said recess.

17. The electronic drinking mug as claimed in claim 16, wherein said recess includes a series of anchor points and said controller is secured to said anchor points by securing elements.

18. The electronic drinking mug as claimed in claim 12, wherein said user interface includes a series of light emitting diodes that are each activated by said controller at distinct temperature levels.

19. The electronic drinking mug as claimed in claim 18, wherein each one of said light emitting diodes is associated with one of said distinct temperature levels, and wherein only one of said light emitting diodes is illuminated at any one time.

20. The electronic drinking mug as claimed in claim 12, further comprising a handle secured to the exterior surface of said outer mug, said handle having a first section secured to said mug that extends substantially perpendicular to a longitudinal axis of said mug, said handle having a second section that extends from the first handle section, the second section extending downwardly toward the lower end of said mug, said second handle section having a free end spaced from the exterior surface of said outer mug.

21. The electronic drinking mug as claimed in claim 20, wherein the second section of said handle is curved.

22. The electronic drinking mug as claimed in claim 20, wherein the first section of said handle is substantially straight.

23. The electronic drinking mug as claimed in claim 12, further comprising an electrical connector provided at the exterior surface of said outer mug for providing electrical power to said controller and said heating element.

24. The electronic drinking mug as claimed in claim 12, wherein the exterior surface of said outer mug tapers inwardly between the upper end and the lower end of said outer mug.

25. An electronic drinking mug comprising:

a mug having an outer surface;

a heating element in thermal communication with said mug for heating a liquid disposed in said mug;

a temperature sensor in communication with said heating element; and

controller means for establishing a desired temperature for said liquid and for selectively activating and deactivating said heating element for heating said liquid in said mug to the desired temperature, wherein said mug has an upper end and a lower end and wherein said controller means is located closer to the upper end of said mug than the lower end of said mug.
