  • Air-conditioning unit with ionizer having self-cleaning electrodes
    Patent number: 10883732
    Abstract: An air conditioner device having a housing or duct with an opening for exit of air and one or more rotatable flaps for adjusting air flow rate and angle exiting through the opening. An ionizer having an electrode is configured to ionize air exiting through the opening, and a cleaning pad is adapted to frictionally remove debris from the electrode consequent to rotation of the flaps without requiring manual operation by a user.
    Type: Grant

  • AIR-CONDITIONING UNIT WITH IONIZER HAVING SELF-CLEANING ELECTRODES
    Publication number: 20190353359
    Abstract: An air conditioner device includes a housing or duct having an opening for exit of air and one or more rotatable flaps for adjusting air flow rate and angle exiting through the opening. Further provided are an ionizer having an electrode for ionizing air exiting through the opening, and a cleaning member adapted to automatically frictionally remove debris from the electrode consequent to rotation of the flaps without requiring manual operation of a user.

  • Bipolar ionizer with external ion imbalance indicator
    Patent number: 9843169
    Abstract: Bipolar ionizer circuit includes a high voltage AC voltage generator having a high potential output and a low potential output, the high potential output being capacitively coupled to respective high potential inputs of a pair of mutually opposite polarity voltage multipliers and the low potential output being capacitively coupled via an auxiliary capacitor to respective low potential inputs of the voltage multipliers. Outputs of the voltage multipliers are connected to respective ionizing electrodes, and an external ion imbalance indicator is connected in parallel to the auxiliary capacitor, which is thereby able to provide automatic balance of the ion current.
