Vacuum cleaner with improved cooling

摘要

A vacuum cleaner has a case (55) including a dust chamber (56) filtering dust included in air, an appliance chamber (57) sucking the filtered air from the dust chamber (56) and discharging the air through a discharge port (57b), and a cord chamber (58) storing a wound electrical cord (81). A fan motor assembly (70) is installed inside the appliance chamber (57) of the case (55) for forcedly sucking the air inside the appliance chamber (57) and discharging the air. An exhaust duct (77) is installed between the fan motor assembly (70) and the discharge port (57b) in the case (55) and guiding the air discharged from the fan motor assembly (70) to the discharge port (57b), and a flowing passage (58a) is disposed between the dust chamber (56) and the cord chamber (58) so that the air is able to flow therein, whereby overheating of case (55) and of the electrical cord (81) can be prevented and the durability and reliability of the cleaner can be enhanced.
