Abstract

Certain embodiments of the present invention provide a deicer system for heating water within a fluid receptacle to prevent ice from forming, the system including a main body configured to be positioned within the fluid receptacle, a heating element adapted to heat the water, a temperature sensor adapted to detect a temperature of the water, a switch adapted to activate and deactivate the heating element, and a control unit in communication with the heating element, the temperature sensor, and the switch. The heating element is supported by the main body. The control unit is adapted to control the heating element using the switch based at least in part on a temperature detected by the temperature sensor.

Claims (50)

1. A deicer system for heating water within a fluid receptacle to prevent ice from forming, the system comprising:

a main body configured to be positioned within the fluid receptacle;

a heating element adapted to heat the water, wherein said heating element is supported by said main body;

a temperature sensor adapted to detect a temperature of the water;

a switch adapted to activate and deactivate said heating element; and

a control unit that is separate and distinct from said switch, said control unit being in communication with said heating element, said temperature sensor, and said switch, wherein said control unit is adapted to control said heating element using said switch based at least in part on a temperature detected by said temperature sensor, wherein said control unit is adapted to be programmed at least in part by an input device that includes a power line receiver, said power line receiver adapted to receive a programming signal superimposed on an alternating current.

2. The system of claim 1 , wherein said temperature sensor is thermally isolated from said heating element.

3. The system of claim 1 , wherein said switch includes a triac.

4. The system of claim 3 , wherein said control unit controls said triac in a proportional mode, wherein the proportional mode includes enabling said triac for less than all of an alternating current cycle.

5. The system of claim 1 , wherein said control unit enables and disables said switch to control said heating element at nodes in an alternating current cycle.

6. The system of claim 1 , wherein said temperature sensor includes at least one of a thermistor, thermocouple, resistance temperature detector, thermometer, and silicon bandgap temperature sensor.

7. The system of claim 1 , wherein said control unit comprises at least one of a processor, a microprocessor, an integrated circuit, and a plurality of discrete logic components.

8. The system of claim 1 , wherein said input device includes at least one of a tilt sensor and a tip sensor.

9. The system of claim 1 , wherein said input device includes a communications port, said communications port adapted to facilitate communication with an external programming device.

10. The system of claim 1 , wherein said input device includes an antenna, said antenna adapted to receive a wireless radio frequency signal.

11. The system of claim 1 , wherein said control unit is adapted to be programmed at least in part by a sequence of being plugged in and unplugged to a power source.

12. The system of claim 1 , wherein said control unit is adapted to control said heating element based at least in part on said temperature detected by said temperature sensor.

13. The system of claim 1 , wherein said control unit is adapted to control said heating element based at least in part on a time interval.

14. The system of claim 1 , further comprising a power input component electrically connected to said heating element.

15. The system of claim 14 , wherein said control unit is located at least in part in said power input component.

16. The system of claim 14 , wherein said power input component includes an air temperature sensor.

17. The system of claim 1 , further including an air temperature sensor adapted to sense the temperature of air outside of said fluid.

18. The system of claim 1 , further including a tilt sensor, wherein at least one operating parameter of said control unit is configured based at least in part on said tilt sensor.

19. The system of claim 1 , further including a plurality of temperature sensors in electrical communication with said control unit.

20. The system of claim 19 , wherein said control unit is adapted to monitor said plurality of temperature sensors.

21. The system of claim 20 , wherein said control unit is adapted to deactivate said heating element based at least in part on said monitored temperature sensors.

22. The deicer of claim 1 , wherein said input device includes a communications port, said communications port adapted to facilitate communication with an external programming device.

23. The deicer of claim 1 , wherein said input device includes an antenna, said antenna adapted to receive a wireless radio frequency signal.

24. The deicer of claim 1 , wherein said control unit is adapted to be programmed at least in part by a sequence of being plugged in and unplugged to a power source.

25. A deicer system for heating water within a fluid receptacle to prevent ice from forming, the system comprising:

a main body configured to be positioned within the fluid receptacle;

a heating element adapted to heat the water, wherein said heating element is supported by said main body;

a temperature sensor adapted to detect a temperature of the water;

a switch adapted to activate and deactivate said heating element; and

a control unit that is separate and distinct from said switch, said control unit being in communication with said heating element, said temperature sensor, and said switch, wherein said control unit is adapted to control said heating element using said switch based at least in part on a temperature detected by said temperature sensor, wherein said control unit is adapted to be programmed at least in part by a sequence of being plugged in and unplugged to a power source.

26. A method for controlling a heating element of a deicer system configured to be positioned within a fluid receptacle to prevent ice from forming within the fluid receptacle, the method comprising:

detecting a temperature of a fluid within the fluid receptacle;

communicating the detected temperature to a control unit, wherein said control unit is adapted to be programmed at least in part by an input device that includes a power line receiver, said power line receiver adapted to receive a programming signal superimposed on an alternating current;

determining whether the detected temperature is below a predetermined value stored within the control unit;

activating a heating element if the detected temperature is below the predetermined temperature; and

using a switch that is separate and distinct from the control unit to activate said heating element.

27. The method of claim 26 , wherein said switch includes at least one of a semiconductor switch and a relay.

28. The method of claim 26 , further including programming the control unit through an input device.

29. The method of claim 26 , further comprising configuring an operating parameter of the control unit based at least in part on a tilt sensor.

30. A method for controlling a heating element of a deicer system configured to be positioned within a fluid receptacle to prevent ice from forming within the fluid receptacle, the method comprising:

detecting a temperature of a fluid within the fluid receptacle;
