に吸引される。The operation of the above construction will be described. When the suction tool main body 21 and the cleaner main body 30 are energized, the rotor of the electric motor 29 built in the rotary brush 26 rotates, and is decelerated by the reduction gear 28 to increase the rotational torque. The rotary brush 26 is driven to rotate. By the rotation of the rotating brush 26, dust adhering to the surface to be cleaned is scraped up, and the scraped-up dust passes through the suction port 24, the extension pipe 34, the hose 3
5, the dust collecting chamber 31 of the cleaner body 30 through the intake passage 40.

The air is returned to the suction tool main body 21 by the exhaust passage 41 formed by the connection pipe 37, and is blown from the suction tool main body 21 to the surface to be cleaned. As a result, dust on the surface to be cleaned is blown off and separated from the surface to be cleaned,
Further, as the rotary brush 26 rotates, dust lurking behind the hairs on the floor such as a carpet is scraped out. The dust released from the surface to be cleaned rides on the airflow returning to the intake port 24 and the airflow of the intake air 42 sucked from the intake port 24, and is carried into the dust collection chamber 31 through the intake passage 40.

The peripheral speed is increased, and the performance of scraping dust from the surface to be cleaned can be improved.

こととなる。The recirculation of the exhaust gas 39 from the electric blower 32 to the suction device main body 21 causes the suction device main body 2
1, the degree of negative pressure in the air blower 1 decreases, and the electric blower 3
In the past, especially in carpet cleaning, in which the exhaust gas 39 was not recirculated, the adsorbing power was reduced moderately, while the rotating brush 26 efficiently brushed the carpet fibers and scraped up dust, while the carpet was being cleaned. The suction tool main body 21 is in a state of being relatively raised from the carpet surface, and the brushing ability and the scraping performance are reduced and the dust collecting ability is reduced. However, the electric motor 29 is built in the rotating brush 26. As a result, the mass of the rotating brush 26 itself increases, which results in compensating for the decrease in the attraction force, so that the relative lifting does not occur and the brushing ability and the scraping performance are maintained.

ととなる。On the other hand, the operating force for moving and operating the suction tool body 21 on the surface to be cleaned is proportional to the mass of the suction tool body 21 and the suction force on the surface to be cleaned. However, as described above, the carpet cleaning has a reduced suction power, and as a result, the operation can be performed lightly, and the usability can be improved.

できるものである。According to the above embodiment, since the exhaust gas 39 containing dust is hardly exhausted indoors, it is possible to reduce the noise of the vacuum cleaner and clean the indoor environment.
The method of returning the exhaust gas 39 discharged from the electric blower 32 to the suction tool main body 21 can be widely used in general household cleaners.

It is formed. A vent hole 48 is formed on the outer peripheral surface of the brush holder 27.

える効果も得られる。The operation and operation according to the above configuration are as follows. In FIG. 2, the exhaust 39 discharged from the electric blower 32 passes through an exhaust passage 41, a part of which is discharged from the front of the suction tool main body 21, and the other flows into the rotating brush 26 and the outer periphery of the brush holder 27. The air is blown and discharged from the ventilation hole 48 formed on the surface to the surface to be cleaned. As a result, dust on the surface to be cleaned is blown off at the opening 25 and separated from the surface to be cleaned, but the exhaust 39 is blown from the rotating brush 26 to the surface to be cleaned, so that the dust is widely and strongly blown to the surface to be cleaned. Thus, the effect of releasing dust from the surface to be cleaned can be increased. In addition, the motor 39 in the rotating brush 26 is forcibly air-cooled by the exhaust gas 39 flowing into the rotating brush 26, and an effect of suppressing an increase in the temperature of the windings of the motor 29 can be obtained.
