Abstract
An electric vacuum cleaner has an air discharge duct and an ozonizer arranged within the exhaust duct for defining air passages through which the exhaust air is constrained to flow and generating a corona discharge laterally across the air passages. Ozone is thereby generated and mixed with the exhaust air. The voltage which generates the corona discharge is varied in accordance with changes in room temperature in order to minimize changes in the quantity of ozone generated.
