Abstract

A clothes dryer apparatus and system that reduces the buildup of electric charges within a dryer drum by introducing ions. The system monitors the voltage within the drum by taking measurements on voltage sensor assembly. The sensor assembly obtains a voltage when two areas of a fabric, or two separate items of the clothing, contact the sensor. If a threshold voltage is obtained, an ion generator introduces cations and anions into the drum of the dryer to neutralize the static charge of the clothing. The reduction of static electricity increases efficiency as the clothing items do not stick together which permits better heat flow and increases safety by reducing the amount of electrical charge within the drum.

Claims (14)

1. A static electricity reduction system for a clothes dryer comprising:

a drum for receiving clothing;

a voltage sensor positioned to measure the voltage of at least a portion of the clothing within the drum;

an ion source in fluid communication with the interior of the drum; and

a controller in electrical communication with the voltage sensor and the ion source wherein the controller activates the ion source upon the voltage sensor measuring a predetermined activation threshold voltage and deactivates the ion source upon the voltage sensor measuring a predetermined cutoff threshold voltage; and

a heat source in fluid communication with the interior of the drum wherein the controller is programmed to cycle between periods in which the heat source is on and the ion source is off and periods in which the heat source is off and the ion source is on.

2. The static electricity reduction system for a clothes dryer of claim 1 wherein the controller deactivates the ion source upon the passage of a predetermined amount of time.

3. The static electricity reduction system for a clothes dryer of claim 1 wherein the ion source further comprises an ion generator fluidly connected to an air compressor.

4. The static electricity reduction system for a clothes dryer of claim 3 wherein the air compressor is a modulating air compressor.

5. The static electricity reduction system for a clothes dryer of claim 1 wherein a non-metallic conduit connects the ion source to the drum.

6. The static electricity reduction system for a clothes dryer of claim 3 wherein a non-metallic conduit connects the ion source to the drum.

7. The static electricity reduction system for a clothes dryer of claim 1 further comprising an ultraviolet light source in visual communication with the interior of the drum.

8. The static electricity reduction system for a clothes dryer of claim 1 further comprising at least one baffle within the drum wherein the baffle contains a conductive material.

9. The static electricity reduction system for a clothes dryer of claim 8 wherein the baffle is a plastic material containing carbon fiber or aluminum shards.
