Abstract

A thermostat comprising a body, a passage, and at least one corona discharge apparatus is provided. The passage passes through the body and extends between an inlet and an outlet. The corona discharge apparatus is positioned within the passage to draw air into the passage through the inlet and to expel the fluid through the outlet such that the thermostat is able to sense the actual ambient air within the structure within which it is mounted without having to rely on free rise convection of the air. As such, the thermostat is able to be flush mounted in a wall or other structure.

Claims

1. A thermostat comprising:

a body defining a passage therethrough and extending between an inlet and an outlet;

an environmental condition sensor positioned within the passage; and

at least one corona discharge apparatus positioned within the passage to draw air into the passage through the inlet and to expel the air through the outlet.

2. The thermostat of claim 1, wherein the environmental sensor senses at least one of a temperature and a humidity of the air.

3. The thermostat of claim 1, further comprising means operatively coupled to the at least one corona discharge apparatus for varying a flow rate of the fluid through the passage.

4. The thermostat of claim 1, further comprising a touch screen user interface.

5. The thermostat of claim 1, wherein the thermostat is adapted for flush mounting in a wall.

6. The thermostat of claim 1, wherein the thermostat further comprises an ozone depletion apparatus for removing ozone from the fluid.

7. The thermostat of claim 1, further comprising control components operatively coupled to the environmental condition sensor, and wherein the passage is configured to exhaust heat generated by the control components.

8. The thermostat of claim 1, wherein the at least one corona discharge apparatus comprises at least one electrode array that is removably mounted in the passage.

9. The thermostat of claim 1, wherein the at least one corona discharge apparatus permits a variable flow of the air to flow through the thermostat.

10. The thermostat of claim 1, wherein the at least one corona discharge apparatus comprises an emitter array in spaced relation to a collector array.

11. The thermostat of claim 1, wherein the environmental condition sensor is a thermistor.

12. The thermostat of claim 1, wherein the at least one corona discharge apparatus is removably positioned in the passage to allow cleaning thereof.

13. The thermostat of claim 1, further comprising a high voltage power supply operatively coupled to the at least one corona discharge apparatus.

14. A thermostat, comprising:

a passage extending between an inlet and an outlet;

a temperature sensor disposed within the passage;

an emitter array positioned in the passage; and

a collector array positioned in the passage and in spaced relation to the emitter array, the emitter array and the collector array cooperatively producing an electric wind in the passage when energized such that air is drawn from an environment into the passage through the inlet, moved past the temperature sensor, and expelled through the outlet into the environment.

15. The thermostat of claim 14, wherein the positively charged emitter array and the negatively charged collector array are disposed proximate the inlet.

16. The thermostat of claim 15, wherein the thermostat further comprises a second emitter array and a second collector array in spaced relation to the second emitter array, the second emitter array and the second collector array disposed proximate the outlet.

17. The thermostat of claim 14, wherein the temperature sensor is a thermistor.

18. A method of controlling a temperature in a structure, comprising the steps of:

producing an electric wind in a passage of a thermostat thereby drawing air from an environment into the passage;

circulating the air past a temperature sensor of the thermostat; and

expelling the fluid into the environment such that the temperature of the air is monitored.

19. The method of claim 18, wherein the method further comprises the step of filtering the air to remove ozone in the electric wind.

20. The method of claim 18, further comprising the step of filtering the air prior to reaching the temperature sensor.
