Abstract

A sterilization, sanitization and/or decontamination device 1 comprising at least a humidifier unit, an ozone generator unit 60, at least one discharge outlet 16 and a controller for controlling the humidifier and ozone generator units, the at least one discharge outlet 16 comprising at least two at least partially converging plates 72, 74 between which substances are discharged.

Claims

1. A sterilisation, decontamination and/or sanitation device comprising at least a humidifier unit, an ozone generator unit, at least one discharge outlet and a controller for controlling the humidifier and ozone generator units, the at least one discharge outlet comprising at least two at least partially converging plates including an upper plate and a lower plate between which air containing ozone is discharged, and wherein the humidifier comprises a water reservoir and at least one discharge nozzle for releasing water droplets as a fine spray, the at least one discharge nozzle being attached to the upper plate of the discharge outlet, remote from the lower plate.

2. A device as claimed in claim 1 wherein the ozone generator is provided within a delivery conduit that leads to the discharge outlet.

3. A device as claimed in claim 2 wherein a fan is provided at the base of the conduit for moving air and ozone through the conduit and out of the discharge outlet.

4. A device as claimed in claim 2 wherein the humidifier, ozone generator, controller and conduit are provided within a housing with the discharge outlet extending from the intended upper surface of the housing.

5. A device as claimed in claim 2 wherein the humidifier, ozone generator, controller and conduit are provided within a housing with the discharge outlet extending from the intended upper surface of the housing and a spacer element is provided between the lower plate of the discharge outlet and the intended upper surface of the housing to provide a minimum distance of 50 mm therebetween.

6. A device as claimed in claim 2 wherein the humidifier, ozone generator, controller and conduit are provided within a housing with the discharge outlet extending from the intended upper surface of the housing and a spacer element is provided between the lower plate of the discharge outlet and the intended upper surface of the housing, the peripheral edges of the plate extending beyond the periphery of the spacer element.

7. A device as claimed in claim 1 wherein a cover plate is provided over the discharge nozzles attached to the upper plate.

8. A device as claimed in claim 1 wherein a mesh or gauze is provided across the opening between the upper and lower plates.

9. A sterilisation, decontamination and/or sanitation device comprising at least a humidifier unit, an ozone generator unit, at least one discharge outlet and a controller for controlling the humidifier and ozone generator units, the at least one discharge outlet comprising at least two at least partially converging plates including an upper plate and a lower plate between which air containing ozone is discharged, and wherein the lower plate has an angle of inclination that is between 1-5 degrees greater than the upper plate.

10. A sterilisation, decontamination and/or sanitation device comprising at least a humidifier unit, an ozone generator unit, at least one discharge outlet and a controller for controlling the humidifier and ozone generator units, the at least one discharge outlet comprising at least two at least partially converging plates including an upper plate and a lower plate between which air containing ozone is discharged, and wherein the ozone generator is provided within a delivery conduit that leads to the discharge outlet, and the humidifier, ozone generator, controller and conduit are provided within a housing with the discharge outlet extending from the intended upper surface of the housing and a spacer element is provided between the lower plate of the discharge outlet and the intended upper surface of the housing to provide a minimum distance of 50 mm therebetween.
