  • Patent number: 8702850
    Abstract: In an electric device (1), an air inlet (3),a gas-liquid contact portion (5), a water collecting portion (6) and an air outlet (7) are arranged in sequential order from upstream of an air duct (2). In a water storage portion (8) the gas-liquid contact portion (5) is dipped and the water collected thereby is stored. An electrolyzing portion (9) generates the electrolyzed water (4) containing an active oxygen species by electrolyzing the water stored in the water storage portion (8). As a result, a compact electric device with an air cleaning function is provided at low cost that is capable of generating water containing an active oxygen species without requiring additional water feed and without generating a by-product.

  • Patent number: 6905580
    Abstract: A water treating apparatus is provided which is capable of producing a hypochlorous acid-containing electrolytic water having a satisfactory sterilizing ability in a household. The water treating apparatus is an apparatus for producing hypochlorous acid in for-treatment water containing a salt by use of an electrochemical reaction which occurs in the for-treatment water when a direct current voltage is applied to at least a pair of electrodes oppositely disposed in the for-treatment water, wherein the direct current voltage to be applied to the electrodes is obtained by smoothing an alternating voltage of domestic use power supply into direct current power of a predetermined voltage, an electrode having titanium covered with a coating containing at least palladium or ruthenium is used as an anode, and at most 90% of the salt added to the for-treatment water is converted into hypochlorous acid by the electrochemical reaction.
