Abstract

An air cleaner for an enclosed electronic device such as an electronic slot machine, for use in areas that have a high level of air contamination from cigarette smoking such as casinos, includes an active field polarized media air cleaner or other filters for removing sub-micron particles, tars and/or volatile organic compounds (VOC'"'"'s). In addition, a shared air cleaner for removing sub-micron particles, tars and/or VOCs is coupled to a plurality of enclosed electronic devices, such as a cluster of electronic slot machines.

Claims

1. A casino gaming device comprising:

an enclosure comprising vents open to air outside the enclosure;

a polarized active media air cleaner comprising an inlet port, an outlet port, and at least one filter;

casino gaming electronic components located within the enclosure;

wherein outside air flows through the inlet port, through the at least one filter, and through the outlet port to create filtered air;

wherein the filtered air cools the electronic components and then exits the enclosure through the vents;

wherein the polarized active media air cleaner comprises two dielectric layers between two outer layers of conductive material and at least two electrodes with a voltage differential therebetween and the at least one filter is located in an electrostatic field created by the at least two electrodes;

wherein the polarized active media air cleaner filters sub-micron particles, tars, and VOCs.

2. The casino gaming device of claim 1, wherein the at least one filter is an active field polarized media air cleaner filter that removes one of sub-micron particles, tars or VOCs from the air flowing through the at least one filter.

3. The casino gaming device of claim 1, wherein the air flow is driven by a fan.

4. The casino gaming device of claim 1, wherein the polarized active media air cleaner is located outside the enclosure.

5. The casino gaming device of claim 1, wherein the polarized active media air cleaner is located inside the enclosure.

6. The casino gaming device of claim 1, wherein the at least one filter comprises a rough filter.

7. The casino gaming device of claim 6, wherein the at least one filter comprises a gaseous contaminant filter.

8. The casino gaming device of claim 7, wherein the at least one filter comprises a fine particle filter.

9. A casino gaming device for providing cooled air to a plurality of electronic components comprising:

a plurality of enclosures comprising vents open to air outside the enclosures and an inlet;

a polarized active media air cleaner comprising an inlet port, an outlet port, and at least one filter;

casino gaming electronic components located within each of the plurality of enclosures;

ductwork that connects the polarized active air media cleaner outlet to each of the plurality of enclosures'"'"' inlets;

wherein air flows through the polarized active media air cleaner inlet port, through the at least one filter, and through the outlet port to create filtered air;

wherein the filtered air passes through the ductwork through the enclosures'"'"' inlets where the filtered air cools the electronic components and then exits the enclosures through the vents;

wherein the polarized active media air cleaner comprises two dielectric layers between two outer layers of conductive material and at least two electrodes with a voltage differential therebetween and the at least one filter is located in an electrostatic field created by the at least two electrodes;

wherein the polarized active media air cleaner filters sub-micron particles, tars, and VOCs.

10. A casino gaming device for providing cooled air to a plurality of electronic components comprising:

a plurality of enclosures comprising vents open to air outside the enclosures;

at least one polarized active media air cleaner comprising an inlet port, an outlet port, and at least one filter;

casino gaming electronic components located within each of the plurality of enclosures;

ductwork that connects a forced air source to each of the plurality of enclosures;

wherein air flows through the ductwork through the at least one polarized media air cleaner inlet port, through the at least one filter, and through the at least one polarized active media air cleaner outlet port to create filtered air;

wherein the filtered air passes into the plurality of enclosures to cool the electronic components and then exits the enclosures through the vents;

wherein the polarized active media air cleaner comprises two dielectric layers between two outer layers of conductive material and at least two electrodes with a voltage differential therebetween and the at least one filter is located in an electrostatic field created by the at least two electrodes;

wherein the polarized active media air cleaner filters sub-micron particles, tars, and VOCs.
