ある。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner, and more particularly to an exhaust gas recirculation (circulation) in which exhaust gas from an electric blower built in a vacuum cleaner body is returned to a floor suction tool or the like via a hose and a pipe. ) -Type vacuum cleaner.

All exhaust air from the electric blower built into the cleaner body is exhausted to the outside through exhaust ports formed on the rear side of the cleaner body.

具合が生じる。That is, dust sucked together with air from a floor suction tool or the like is taken into the cleaner body via pipes and hoses, and the air from which dust has been removed by a dust-collecting paper pack or the like is used to drive a motor of an electric blower. After the part is cooled, it is discharged to the outside from the exhaust port. However, since all the exhaust from the electric blower is discharged, the part is blown to the outside with considerable force. Therefore, there is a problem that dust stagnates on the floor or carpet due to the exhaust air soars and scatters in the room.

路を形成して成る電気掃除機が提案されている。Conventionally, a hose, a pipe, and a suction tool connected to a cleaner main body are electrically driven together with an intake passage for the purpose of reducing the exhaust air blown out to the outside and improving the dust collecting effect. 2. Description of the Related Art A vacuum cleaner has been proposed in which an exhaust ring channel for recirculating exhaust gas from a blower is formed.

してしまう。However, when all the exhaust air from the electric blower is passed through the motor drive unit, and the exhaust air that has cooled the motor drive unit is circulated, the exhaust air whose temperature has increased by cooling the motor drive unit circulates. As a result, the temperature of the cleaner itself, hoses and pipes, and the motor itself are also increased, resulting in discomfort when using the vacuum cleaner, and further, deformation of the cleaner body, deterioration of the motor, and destruction of the motor. There is fear. Also, the exhaust air that has cooled the motor drive
It contains carbon powder generated by the contact between the carbon brush of the motor and the commutator, and when this circulates, the carbon powder adheres to the exhaust circulation path and becomes dirty, or is blown out from the suction tool and the cleaning surface becomes dirty. Failure occurs. In addition, when all the exhaust gas is recirculated, the amount of outside air newly sucked from the suction tool decreases, so that the suction force (suction force) also decreases.

うにしたものを既に提案している。Accordingly, the applicant of the present invention has formed an exhaust port on the outer peripheral portion of a fan cover for covering a centrifugal fan of a conventional general electric blower, and a part of the exhaust air discharged from the centrifugal fan is similar to the conventional one. It has already been proposed to use it to cool the motor drive unit and then discharge it from the main body exhaust port to the outside, and discharge the remainder from the fan cover exhaust port to the exhaust circulation channel without passing through the motor drive unit. .

抵抗によって決まり、所望の割合になるように設計され
る。In the above construction, the ratio between the amount of exhaust gas to be circulated and the amount of exhaust gas discharged to the outside from the main body exhaust port is determined by the flow resistance of the exhaust circulation passage from the electric blower to the suction device. And the flow path resistance of the exhaust path to the main body exhaust port, and is designed to have a desired ratio.

るので、このような使用形態には対応できない。However, when the ratio of the exhaust gas recirculation is set to be high, the amount of exhaust air from the exhaust port of the cleaner body is reduced, so that the scattering of dust due to the exhaust air is reduced, but the suction force (suction force) cannot be so strong. Therefore, in order to clean a large amount of dust in a short time, it is necessary to increase the amount of exhaust air from the exhaust port of the cleaner body. That is, in the case of cleaning requiring suction force, for example, when using a gap nozzle formed with a narrow suction port, dust to be sucked is generated by blowing out from the suction port of the gap nozzle when the exhaust gas flow rate increases. Conversely, it will scatter, so we want to increase the amount of exhaust from the exhaust port of the cleaner body, reduce the exhaust recirculation flow, and increase the suction power, but the ratio of the exhaust recirculation is fixedly set at the time of design, so this way Cannot be used for various usage patterns.
