Next, the operation of the vacuum cleaner 1 according to this embodiment will be described.

First, the user of the vacuum cleaner 1 connects the pipe portion 3, that is, the dust collecting hose 21, the extension pipe 25, and the suction port body 26 to the vacuum cleaner body 2 in an appropriate order.

Next, the power cord 11 is pulled out from the cleaner body 2, and the power plug 14 is connected to an outlet (not shown) for supplying commercial power.

Next, the user of the vacuum cleaner 1 grips the grip portion 23 and operates the start switch 24b.

Then, the control unit 9 drives the electric blower 8 according to the operation mode set by the start switch 24b. By driving the electric blower 8, a negative pressure is generated in the vacuum cleaner main body 2 and the pipe portion 3, and the vacuum cleaner 1 sucks air from the suction port 38 and the dust suction port 39 of the suction port body 26.

Next, the user of the vacuum cleaner 1 places the suction port body 26 on the surface to be cleaned, and reciprocates the hand operation tube 22 and the extension tube 25 back and forth while holding the grip portion 23.

Then, the suction port body 26 sucks dust from the surface to be cleaned together with air (dust-containing air) from the dust suction port 39 while traveling back and forth on the surface to be cleaned. Dust-containing air sucked from the dust suction port 39 is guided to the cleaner body 2 through the connection pipe 32.

At this time, the suction port body 26 also sucks air from the suction port 38. The air sucked from the intake port 38 is guided to the moving blade portion 47 by the guide blade portion 46 of the turbines 41 and 41A, passes through while rotating the moving blade portion 47, and is sucked from the dust suction port 39 in the suction chamber 36. It joins the dust-containing air and reaches the connecting pipe 32. The rotation of the moving blade portion 47 is input to the planetary gear mechanism 43 via the turbine shaft 42 to drive the rotary cleaning body 44. By driving the rotary cleaning body 44, the suction port body 26 sweeps up dust on the surface to be cleaned and polishes the surface to be cleaned. The dust swept up by the rotary cleaning body 44 is sucked into the suction port body 26 from the dust suction port 39. At this time, the flow of the air F sucked into the suction chamber 36 from the auxiliary intake port 60 is blown to the cleaning body 59 of the rotary cleaning body 44 to assist the rotation of the rotary cleaning body 44.

The dust-containing air sucked into the suction port body 26 sequentially passes through the extension pipe 25, the hand operation pipe 22 and the dust collection hose 21, and is then guided to the cleaner body 2.

The dust-containing air guided to the vacuum cleaner body 2 is sucked into the dust separation and collection unit 7 and separated into dust and air. The separated dust is collected by the dust separation and collection unit 7. On the other hand, the separated air passes through the dust separation and collection unit 7 and is sucked into the electric blower 8 and is exhausted from the cleaner body 2.

Thus, the vacuum cleaner 1 collects the dust sucked from the suction port body 26.

The rotary cleaning body units 33 and 33A, the suction port body 26, and the electric vacuum cleaner 1 according to the present embodiment are configured so that the rotational diameter of the rotary cleaning body 44 and the diameter of the turbines 41 and 41A are approximately the same, and the turbines 41 and 41A are configured. (More specifically, the rotor blade portion 47), the drive shaft that is the rotation center of the turbine shaft 42 and the sun gear 51, the driven shaft that is the revolution center of the planetary gear 52 (that is, the rotation center of the carrier 54), and the rotary cleaning body 44 It becomes possible to arrange the rotation centers on substantially the same straight line (rotation axis C), and elements that cause mechanical loss due to friction or sliding when transmitting torque from the turbines 41 and 41A to the rotary cleaning body 44 as much as possible. Can be reduced. Specifically, this mechanical loss substantially depends on the mechanical loss of the planetary gear mechanism 43, and the loss of the entire mechanism for driving the rotary cleaning body 44 can be easily reduced.

Further, the rotary cleaning body units 33 and 33A, the suction port body 26, and the electric vacuum cleaner 1 according to the present embodiment are cases where the torque generated by the turbines 41 and 41A is not sufficient to directly drive the rotary cleaning body 44. However, since the planetary gear mechanism 43 having a relatively large reduction ratio as compared with a reduction gear composed of a spur gear or a bevel gear that can be incorporated in the same capacity (volume) is provided, the carpet is laid and the cleaning coefficient is high. Also on the surface, a torque that can reliably drive the rotary cleaning body 44 can be obtained.

Furthermore, the rotary cleaning body unit 33A according to the present embodiment is configured with the turbine 41, the turbine shaft 42, the planetary gear mechanism 43, and the rotary cleaning body 44 as a single module so that the handling convenience and the suction port body 26 can be improved. Improve assembly.

Therefore, according to the vacuum cleaner 1, the suction port body 26, and the rotary cleaning body units 33 and 33A according to the present embodiment, the rotary cleaner 44 having the turbines 41 and 41A as a prime mover is provided, and the suction work of the vacuum cleaner 1 is performed. The rotary cleaning body 44 can be driven with high torque without reducing the rate.
