Abstract
A method for monitoring ozone generation in an oxygen containing gas within a chamber in an ozone generator in which ozone is generated comprising: sensing with a sensor a parameter within the chamber with time; wherein the parameter is selected from the group consisting of sound and electromagnetic radiation and estimating an amount of ozone generated with time as a function of the parameter sensed by the sensor.
Claims20
A method for controlling operation of an ozone generator in which ozone is generated by converting oxygen within an oxygen containing gas in a corona discharge mechanism by corona discharge of electromagnetic radiation through the oxygen containing gas by providing electrical power to the corona discharge mechanism to render the corona discharge mechanism operative to convert oxygen to ozone, and in which the amount of ozone generated with time is a function of one or more of the voltage, amperage and frequency of the electrical power provided to the corona discharge mechanism,
- the method comprising:
- sensing with a sound sensor sound created by the corona discharge mechanism while operative to convert oxygen into ozone with time,
- estimating an amount of ozone generated with time as a function of the sound sensed by the sound sensor and
- controlling the amount of ozone generated with time by controlling one or more of the voltage, amperage and frequency of the electrical power provided to the corona discharge mechanism as a function of the estimate of the amount of ozone generated with time.
A method of operating a hand cleaner dispenser comprising:
- generating ozone in an ozone generator in a chamber in which ozone is generated by converting oxygen in an oxygen containing gas to ozone to produce ozonated air containing ozone in a corona discharge mechanism by the corona discharge of electromagnetic radiation through the oxygen containing gas by providing electrical power to the corona discharge mechanism to render the corona discharge mechanism operative to convert oxygen to ozone, and in which the amount of ozone generated with time is a function of one or more of the voltage, amperage and frequency of the electrical power provided to the corona discharge mechanism,
- passing the ozonated air and a liquid through a foam generator to generate a foamed mixture of the ozonated air and the liquid out a discharge outlet,
- producing sound in the generation of the ozone,
- sensing with a sound sensor sound created by operation of the corona discharge mechanism,
- estimating an estimate of the amount of ozone generated with time as a function of the sound sensed by the sound sensor,
- controlling the amount of ozone generated with time by controlling one or more of the voltage amperage and frequency of the electrical power provided to the corona discharge mechanism as a function of the estimate of the amount of ozone generated with time.
