Abstract
A water purifier includes an ozone generator and a filter. Water is passed through the ozone generator wherein ozone is produced by electrolysis to sterilize the water. The sterilized water can be drawn-off after being sterilized, or can be conducted through the filter and then drawn-off. The water exiting the ozone generator can be conducted through a convoluted mixing conduit to mix the water and ozone. The ozone generator includes a cylindrical bobbin having positive and negative electrodes wound alternatingly around its outer surface. The electrodes pass across water channels formed in the bobbin outer surface. Water is passed through the channels whereby ozone is formed by electrolysis.
