System and method for detecting and removing odor and bacteria from a sealed volume of an appliance using ozone

An appliance, comprising:

• a housing defining a sealable volume;
• an ozone generator operable to dispense ozone into the sealable volume;
• an ozone detection device operable to detect a concentration level of ozone within the sealable volume;
• a controller communicatively coupled with the ozone generator and the ozone detection device, the controller configured to:
• i) cause, at a predetermined injection interval, the ozone generator to inject a predefined dosage of ozone into the sealable volume;
• ii) receive, from the ozone detection device, an input indicative of the concentration level of ozone within the sealable volume;
• iii) determine the concentration level of ozone within the sealable volume based at least in part on the received input;
• and
• iv) ascertain whether the determined concentration level has reached a maximum concentration level threshold, and
• wherein the controller iteratively i) causes, ii) receives, iii) determines, and iv) ascertains until the determined concentration level reaches the maximum concentration level threshold or a maximum generator on time has elapsed.
