Abstract

An apparatus for generating an effective concentration of ozone for killing bacteria, viruses and other harmful microorganisms includes a housing having an ozone chamber defining an enclosed space for containing elevated concentrations of ozone. The ozone chamber includes ports providing access to the interior of the ozone chamber. A second chamber of the apparatus houses an ozone reactor. A programmable control circuit operates both the ozone reactor and a pump for directing ambient air to the ozone reactor. The control circuit includes a motion detector mounted in the ozone chamber for activating the ozone generator of the invention and initiating the generation of ozone directed into the ozone chamber of the apparatus of the invention.

Claims

1. An ozone generator comprising:

a) a housing contoining first and second enclosed compartments;

b) said first compartment including access means permitting a user'"'"'s hands and forearms to be inserted into said first compartment;

c) ozone generating means housed in said second compartment of said housing;

d) a conduit having one end connected to an outlet end of said ozone generating means and an opposite end opening into said first compartment;

e) means for controlling the operation of said ozone generating means; and

f) means for automatically activating said ozone generating means upon insertion of a user'"'"'s hands and forearms into said first compartment.

2. The apparatus of claim 1 including a pump for pumping ambient air to said ozone generating means.

3. The apparatus of claim 2 including a silica gel filter for removing water vapor from the air pumped into said ozone generating means.

4. The apparatus of claim 1 including a control circuit for controlling operation of said ozone generating means.

5. The apparatus of claim 4 wherein said control circuit includes a timer for controlling the run cycle of said ozone generating means.

6. The apparatus of claim 5 including a time delay relay circuit operatively connected to an exhaust fan and set for delayed operation for removing ozone from said first enclosed compartment.

7. The apparatus of claim 1 wherein said activating means includes a motion detector housed in said first enclosed compartment for energizing a control circuit for activating said ozone generating means upon sensing motion in said first enclosed compartment.

8. The apparatus of claim 7 including a bypass switch for bypassing said motion detector for repetitive and continuos operation of said ozone generator.

9. The apparatus of claim 1 including a DC to AC converting circuit for operation of said ozone generating means.

10. The apparatus of claim 1 wherein said first enclosed compartment includes fabric mounted on one or more interior walls thereof for neutralizing ozone generated by said ozone generating means.

11. The apparatus of claim 1 wherein said access means comprises arm holes formed in a top panel of said first compartment.

12. The apparatus of claim 11 including sleeves circumscribing said arm holes providing a passageway for inserting a user'"'"'s arms and forearms into said first compartment.

13. An ozone generator comprising:

a) a housing containing first and second enclosed compartments;

b) said first compartment including access means permitting a user'"'"'s hands and forearms to be inserted into said first compartment;

c) ozone generating means housed in said second compartment of said housing operatively connected to a control circuit for activating said ozone generating means, and wherein upon activation said ozone generating means releases ozone into said first compartment; and

d) wherein said first compartment includes fabric mounted on the interior thereof for aiding in the neutralization of ozone within said first compartment.
