Abstract:
To prevent excessive circulation of exhaust air between a suction port and an external discharge port in a vacuum cleaner.SOLUTION: A vacuum cleaner comprises a suction port provided in a bottom surface opposed to an object to be cleaned, an electric air blower for sucking air to the inside via the suction port, and an external discharge port for discharging air sucked from the suction port to the outside. Air sucked by the electric air blower is heated, and heated air is blown to the object to be cleaned from external discharge port. The suction port and the external discharge port are arranged so that air discharged from the external discharge port is not sucked from the suction port when the suction port is closely opposed to the object to be cleaned. Air is discharged from the external discharge port to the outside while air is sucked from the suction port.SELECTED DRAWING: Figure 5
