Abstract

The vacuum cleaner includes a hose connection port provided at the front end of a vacuum cleaner body and connecting a connection hose, an exhaust port provided at the vacuum cleaner body, the blower commutator motor provided in the vacuum cleaner body, a filter provided in an air passage between the commutator motor and the exhaust port and an ozone generator provided in an air passage from the filter to the exhaust port and adjacent to the filter. The ozone generator is controlled to be operated in a predetermined time period after a blower is stopped. To provide a vacuum cleaner allowing sterilization of a filter disposed on the downstream side of a blower commutator motor.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, in particular to the sterilization of a filter provided between a commutator motor for a blower and an exhaust port of a vacuum cleaner body. Background technique [0002] In conventional electric vacuum cleaners, the dust-containing air sucked in from the suction port enters the dust collection chamber and is removed by the dust collection bag, and then is distributed to the exhaust port for releasing the air to the outside of the machine through the blower, the motor for the blower, and The air is sent to the return exhaust port of the return flow path for exhaust (refer to JP-A-2001-178664). In addition, in this electric vacuum cleaner, a commutator motor is used as the motor for the blower similarly to the conventional general structure. In this commutator motor, carbon powder is generated and scattered by the contact between the carbon brushes of the motor and the commutator due to the ...
