Abstract

An air cleaner (100) is provided according to an embodiment of the invention. The air cleaner (100) includes a high voltage power supply (108) configured to provide a high voltage to a collector cell (114) and a shut-down circuit (111) coupled to the high voltage power supply (108). The shut-down circuit (111) is configured to monitor an electrical current supplied to the collector cell (114), remove electrical power to the collector cell (114) if the electrical current exceeds a predetermined cell current threshold for a predetermined time period, and generate an indication if the electrical power is removed from the collector cell (114).

Claims (23)

1. An air cleaner (100), comprising a high voltage power supply (108) configured to provide a high voltage to a collector cell (114), with the air cleaner (100) being characterized by:

a shut-down circuit (111) coupled to the high voltage power supply (108) and configured to monitor an electrical current supplied to the collector cell (114), remove electrical power to the collector cell (114) if the electrical current exceeds a predetermined cell current threshold for a predetermined time period, and generate an indication if the electrical power is removed from the collector cell (114).
2. The air cleaner (100) of claim 1, with the collector cell (114) comprising an ionizer.
3. The air cleaner (100) of claim 1, with the collector cell (114) comprising an electrostatic precipitator.
4. The air cleaner (100) of claim 1, with the collector cell (114) comprising an electrostatic precipitator in combination with an ionizer.
5. The air cleaner (100) of claim 1, further comprising an air moving device (116) and wherein electrical power to the air moving device (116) is maintained when the electrical power to the collector cell (114) is removed.
6. The air cleaner (100) of claim 1, with generating the indication comprising illuminating a check collector cell indicator (131).
7. The air cleaner (100) of claim 1, with generating the indication comprising blinking a check collector cell indicator (131).
8. The air cleaner (100) of claim 1, with the shut-down circuit (111) being further configured to restore the electrical power to the collector cell (114) upon a power cycle and monitor the electrical current and remove electrical power to the collector cell (114) if the electrical current exceeds a predetermined cell current threshold for a predetermined time period after restoring the electrical power.
9. A shut-down method for a collector cell of an air cleaner, the method comprising:

monitoring an electrical current supplied to the collector cell;

removing electrical power to the collector cell if the electrical current exceeds a predetermined cell current threshold for a predetermined time period; and generating an indication if the electrical power is removed from the collector cell.
10. The method of claim 9, with the collector cell comprising an ionizer.
11. The method of claim 9, with the collector cell comprising an electrostatic precipitator.
12. The method of claim 9, with the collector cell comprising an electrostatic precipitator in combination with an ionizer.
13. The method of claim 9, further comprising an air moving device and wherein electrical power to the air moving device is maintained when the electrical power to the collector cell is removed.
14. The method of claim 9, with generating the indication comprising illuminating a check collector cell indicator.
15. The method of claim 9, with generating the indication comprising blinking a check collector cell indicator.
16. The method of claim 9, further comprising:

restoring the electrical power to the collector cell upon a power cycle; and monitoring the electrical current and removing electrical power to the collector cell if the electrical current exceeds a predetermined cell current threshold for a predetermined time period after restoring the electrical power.
17. A shut-down method for a collector cell of an air cleaner, the method comprising:

monitoring an electrical current supplied to the collector cell;

removing electrical power to the collector cell if the electrical current exceeds a predetermined cell current threshold for a predetermined time period;
generating an indication if the electrical power is removed from the collector cell;

restoring the electrical power to the collector cell upon a power cycle;
monitoring the electrical current; and removing the electrical power to the collector cell and generating the indication if the electrical current exceeds the predetermined cell current threshold for the predetermined time period after restoring the electrical power.
18. The method of claim 17, with the collector cell comprising an ionizer.
19. The method of claim 17, with the collector cell comprising an electrostatic precipitator.
20. The method of claim 17, with the collector cell comprising an electrostatic precipitator in combination with an ionizer.
21. The method of claim 17, further comprising an air moving device and wherein electrical power to the air moving device is maintained when the electrical power to the collector cell is removed.
22. The method of claim 17, with generating the indication comprising illuminating a check collector cell indicator.
23. The method of claim 17, with generating the indication comprising blinking a check collector cell indicator.
