FIG. 1 is a longitudinal sectional view of a cleaner body according to a fifth embodiment of the present invention.

In FIG. 1, a centrifugal dust collector 19 is located below the electric blower 11.

The operation of the above configuration is as follows.

By the suction force of the electric blower 11, the dust on the surface to be cleaned which has been scooped up by the rotating brush 17 is sucked by the suction body 1.
Inhale from 2. The sucked dust is introduced into the centrifugal dust collecting unit 19 from the air inlet 20 through the air intake passage 26 communicating with the air suction body 12 together with the air.

The air containing dust introduced from the intake port 20 rotates as a vortex along the inner peripheral surface of the centrifugal force collecting unit 19 and is collected along the inner peripheral surface of the dust box 21.
Large dust collects at the bottom of the dust box 21 due to gravity, and small dust is sucked into the upper part of the dust box 21 on the electric blower 11 side, and only extremely fine dust adheres to the filter 24.

That is, it is possible to separate the dust into large and small pieces, so that the dust is not clogged, high dust collecting performance can be obtained for a long time, and the usability can be improved.

(Embodiment 6) Next, a sixth embodiment of the present invention will be described with reference to FIGS.

FIG. 11 is a longitudinal sectional view of a cleaner body according to a sixth embodiment of the present invention, and FIG. 12 is an operation diagram of the cleaner body.

In the figures, components having the same reference numerals as those of the above-described embodiment have the same structure, and therefore description thereof will be omitted.

The centrifugal dust collector 19 is located above the electric blower 11.
Is located.

The operation of the above configuration is as follows.

The distance B between the floor and the electric blower 11 is shortened, and the center of gravity of the electric blower 11 is located below, so that the load on the handle 14 can be reduced and the usability is improved.

(Embodiment 7) Next, a seventh embodiment of the present invention will be described with reference to FIGS.

FIG. 14 is a partially enlarged view of a suction port showing a seventh embodiment of the present invention, and FIG. 15 is a bottom view of the same.
In the drawings, the components having the same reference numerals as those of the above-described embodiment have the same structure, and thus the description thereof will be omitted.

Reference numeral 50 denotes a protrusion formed near the inlet of the suction port 51 of the suction body 12 so as to be substantially perpendicular to the rotation direction of the rotating brush 17. Reference numeral 52 denotes a rib formed in the suction passage 26 near the inlet of the suction port 51 of the suction body 12, and only the inlet portion is formed from the cross-sectional area of the other suction passage 26 communicating with the suction port 20 of the centrifugal dust collecting portion 19. I'm making it smaller.

The operation of the above configuration is as follows. The suction force of the electric blower 11 sucks the dust on the surface to be cleaned which has been scooped up by the rotating brush 17 from the suction port 51. At this time, if dust such as a relatively heavy clip is sucked, the rotation of the rotating brush 17 causes the rotating brush 17 to rotate.
Is kept from rotating around the rotating brush 17 to prevent it from being easily sucked by the suction port 51. When dust such as a clip rotating around the rotary brush 17 is sucked and moved near the suction port 51, The dust hits the protrusion 50 and stops its rotation, and at the same time, can be sucked into the suction port 51.

Next, a description will be given of a partially cutaway plan view of the vacuum cleaner of FIG. When relatively large dust is sucked, the sucked dust is sucked into the rib 52 at the entrance of the suction port 51.
Is not sucked inside. In other words, if large dust is clogged in the suction port 51, it can be easily removed. However, if dust is clogged in the other suction passage 26 communicating with the suction port 20 of the centrifugal dust collecting section 19, it takes a lot of trouble to remove the dust.
Since the cross-sectional area of the passage is reduced by the rib 52 at the inlet of the suction port 51, no pressure loss occurs in the suction passage 26, and a decrease in suction force can be prevented.

Here, the suction port 5 is formed by the rib 52.
Although the cross-sectional area of the passage is reduced at the inlet portion, it goes without saying that the same effect can be obtained with other configurations.
