Abstract

Certain embodiments of the present invention provide a deicing system configured to prevent ice from forming in a water containment vessel. The system includes a heating element configured to heat the water within the containment vessel, a first temperature sensor and a second temperature sensor. The first temperature sensor is electrically connected to the heating element through an electrical path and may be configured to monitor water temperature. The second temperature sensor is electrically connected to the heating element through the electrical path and may be configured to monitor heating element temperature. At least one of the temperature sensors may include a reset button.

Claims (34)

1. A deicing system configured to prevent ice from forming in a water containment vessel, the deicing system comprising:

a heating element configured to heat the water within the containment vessel;

a first temperature sensor electrically connected to said heating element through an electrical path, said first temperature sensor configured to monitor water temperature;

a second temperature sensor electrically connected to said heating element through said electrical path, said second temperature sensor monitoring heating element temperature;

one or both of a first additional temperature sensor that is configured to monitor the water temperature, or a second additional temperature sensor that monitors the heating element temperature; and

at least one alert device that is activated when said first temperature sensor does not act in synchronization with said first additional temperature sensor and/or when said second temperature sensor does not act in synchronization with said second additional temperature sensor.

2. The deicing system of claim 1 , wherein each of said first and second temperature sensors comprises a thermostat.

3. The deicing system of claim 1 , wherein said first temperature sensor closes said electrical path when the water temperature is at or below a low point, and wherein said first temperature sensor opens said electrical path when the water temperature is at or above a high point.

4. The deicing system of claim 3 , wherein said second temperature sensor opens said electrical path when the heating element is at or above an overheated point that exceeds the high point.

5. The deicing system of claim 1 , wherein said second temperature sensor comprises a reset button, wherein said reset button is configured to be manually engaged to close said electrical path after said second temperature sensor opens said electrical path.

6. A deicing system configured to prevent ice from forming in a water containment vessel, the deicing system comprising:

a heating element configured to heat the water within the containment vessel;

a first temperature sensor electrically connected to said heating element through an electrical path, said first temperature sensor opening said electrical path based on a detected temperature;

a reset button operatively connected to said first temperature sensor, said reset button configured to be manually engaged to close said electrical path after said first temperature sensor opens said electrical path based on the detected temperature;

an additional temperature sensor that acts as a backup to said first temperature sensor; and

an alert device that is activated when said first temperature sensor does not act in synchronization with said additional temperature sensor.

7. The deicing system of claim 6 , wherein said first temperature sensor monitors heating element temperature.

8. The deicing system of claim 6 , comprising a second temperature sensor electrically connected to said heating element through said electrical path.

9. The deicing system of claim 8 , wherein said second temperature sensor monitors water temperature.

10. The deicing system of claim 9 , wherein said second temperature sensor closes said electrical path when the water temperature is at or below a low point, and wherein said first temperature sensor opens said electrical path when the water temperature is at or above a high point.

11. The deicing system of claim 10 , wherein said first temperature sensor opens said electrical path when the heating element is at or above an overheated point that exceeds the high point.

12. The deicing system of claim 6 , wherein said first temperature sensor comprises a thermostat.

13. A method of preventing ice from forming within a water containment vessel, the method comprising:

detecting a temperature of the water within the water containment vessel through a first thermostat;

activating a heating element when the temperature of the water is below a predetermined low point;

deactivating the heating element when the temperature of the water is at or above a predetermined high point;

detecting a heating element temperature with a second thermostat;

preventing the heating element from activating when the heating element temperature is at or above an overheated point that exceeds the predetermined high point;

backing-up one or both of the first and second thermostats with at least one backup temperature sensor; and

providing an audible or visual alert when the one or both of the first and second thermostats does not act in synchronization with the at least one backup temperature sensor.

14. The method of claim 13 , comprising manually resetting the second thermostat after said preventing in order to reactivate the heating element.

15. The method of claim 13 , wherein said activating a heating element when the temperature of the water is below a predetermined low point comprises closing an electrical path between the first thermostat and the heating element, and wherein said deactivating the heating element when the temperature of the water is at or above a predetermined high point comprises opening the electrical path between the first thermostat and the heating element.

16. The method of claim 13 , wherein said preventing the heating element from activating when the heating element temperature is at or above an overheated point that exceeds the predetermined high point comprises keeping an electrical path between the first thermostat and the heating element open until the second thermostat is manually reset.

17. The method of claim 13 , wherein said overheated point is below a damaging temperature that can cause damage to the heating element and/or the water containment vessel.
