Abstract

A device for sanitizing objects using ozone is disclosed having a container defining an enclosed space and a selectively closeable opening for enclosing the space, an ozone generator, an ozone converter, a controller, and a timer working together to generate a predetermined concentration of ozone within the enclosed space and maintain approximately the same concentration for a predetermined period of time. Also disclosed are assemblies and methods detecting and warning of entrapment within the enclosure and halting ozone production when it occurs. Further disclosed are devices and methods for coupling a maintenance device to the sanitizing system to perform various maintenance operations such as adjusting operational control parameters, and observing conditions within the enclosed chamber in real-time such as temperature, humidity, and ozone concentration.

Claims

1. An ozone sanitizing system comprising:

a container defining an interior space, the interior space being accessible by a selectively closeable opening;

an ozone generator having a generator outlet in fluid communication with the interior space, wherein the ozone generator has an ultraviolet light in fluid communication with the atmosphere, and wherein the ultraviolet light converts at least a portion of the atmosphere to ozone gas;

an ozone converter having a converter inlet in fluid communication with the interior space;

a timer;

an ozone sensor in fluid communication with the interior space, and;

a controller responsive to the ozone sensor and the timer for controlling the ozone generator and the ozone converter.

2. The ozone sanitizing system of claim 1 further comprising a temperature sensor, or a humidity sensor, or any combination thereof, in fluid communication with the interior space.

3. The ozone sanitizing system of claim 1 further comprising:

a locking mechanism configured to maintain the closeable opening in place;

wherein the locking mechanism is responsive to the controller.

4. The ozone sanitizing system of claim 1 further comprising

a floor within the interior space, and;

a sensing device responsive to objects resting on the floor;

wherein the controller is configured to stop ozone generation if the sensing device indicates an object resting on the floor.

5. The ozone sanitizing system of claim 1 wherein the closeable opening is configured to substantially hermetically seal the opening.

6. The ozone sanitizing system of claim 1 wherein the controller is configured to keep the closeable opening closed while ozone concentrations within the interior space are above a predetermined level.

7. The ozone sanitizing system of claim 1 further comprising:

a memory accessible by the controller for storing one or more operating parameters and a current sanitizing cycle, and;

a control panel coupled to the controller, the control panel having one or more indicators for indicating at least the current sanitizing cycle.

8. The ozone sanitizing system of claim 7 wherein the memory is configured to store one or more current state values including a current temperature measured by a temperature sensor in fluid communication with the interior space, a current humidity measured by a humidity sensor in fluid communication with the interior space, a current ozone concentration measured by the ozone sensor, a sanitizing cycle, a total time of ozone production, a total time of ozone conversion, a sanitizing cycle duration, or any combination thereof.

9. The ozone sanitizing system of claim 7 further comprising a coupling device coupled to the controller for coupling the controller to a maintenance device operable to adjust one or more operating parameters.

14. The ozone sanitizing system of claim 1 further comprising a temperature sensor, or a humidity sensor, or any combination thereof, in fluid communication with the interior space.

15. The ozone sanitizing system of claim 1 further comprising:

a locking mechanism configured to maintain the selectively closeable opening in a closed state, wherein the locking mechanism is responsive to the controller.

16. The ozone sanitizing system of claim 1 further comprising

a floor within the interior space, and;

a sensing device responsive to objects resting on the floor;

wherein the controller is configured to stop ozone generation if the sensing device indicates an object resting on the floor.

17. The ozone sanitizing system of claim 1 wherein the controller is configured to keep the closeable opening closed while ozone concentrations within the interior space are above a predetermined level.

18. The ozone sanitizing system of claim 1 further comprising:

a memory accessible by the controller for storing one or more operating parameters and a current sanitizing cycle, and;

a control panel coupled to the controller, the control panel having one or more indicators for indicating at least the current sanitizing cycle.

19. The ozone sanitizing system of claim 16 further comprising a coupling device coupled to the controller for coupling the controller to a maintenance device operable to adjust one or more operating parameters.

10. An ozone sanitizing system comprising:

a container defining an interior space, the interior space being accessible by a selectively closeable opening, wherein the container is substantially hermetically sealed when the selectively closeable opening is closed;

an ozone generator having a generator outlet in fluid communication with the interior space, wherein the generator is configured to convert diatomic oxygen in at least a portion of the atmosphere to ozone gas;

an ozone converter having a converter inlet in fluid communication with the interior space, wherein the ozone converter is configured to convert ozone gas to diatomic oxygen when the container is substantially hermetically sealed;

a timer;

an ozone sensor in fluid communication with the interior space, and;

a controller responsive to the ozone sensor and the timer for controlling the ozone generator, the ozone converter, and the selectively closeable opening, wherein the controller is configured to control the ozone generator to produce ozone gas when the container is substantially hermetically sealed.

11. The ozone sanitizing system of claim 10, wherein the ozone generator includes an ultraviolet light in fluid communication with the atmosphere in the container, and wherein the diatomic oxygen in a portion of the atmosphere is converted to ozone using the ultraviolet light.

12. The ozone sanitizing system of claim 10, wherein the ozone generator includes a cold plasma generator in fluid communication with the atmosphere in the container, and wherein the diatomic oxygen in a portion of the atmosphere is converted to ozone using the cold plasma generator.

13. The ozone sanitizing system of claim 10, wherein the ozone generator is configured to produce ozone gas by electrolytic ozone generation that includes splitting water into hydrogen, diatomic oxygen, and ozone gas.

20. An ozone sanitizing system comprising:

a container defining an interior space, the interior space being accessible by a selectively closeable opening;

an ozone generator having a generator outlet in fluid communication with the interior space, wherein the ozone generator converts at least a portion of the atmosphere to ozone gas by any of an ultraviolet light, a cold plasma generator, or electrolytic ozone generation that includes splitting water into hydrogen, diatomic oxygen, and ozone gas;

an ozone converter having a converter inlet in fluid communication with the interior space;

a timer;
