  Referring to FIG. 15, the inner cylinder unit 530 includes an upper cup cover 537 accommodating the filter unit 550, a lower dust partition 535, and an inner cylinder 533 connecting the two. An opening is formed at the bottom of the cup cover 537 to which the inner cylinder 533 is connected. A slit-like outlet 533 b is formed around the inner cylinder 533, and a mesh-like filter (not shown) is disposed at the outlet 533 b. The dust partition 535 includes a flange 535a having an outer diameter larger than that of the inner cylinder 533, a large diameter cylindrical portion 535b surrounding the outer periphery of the flange, and a small diameter cylindrical portion 535c whose lower end is in contact with the bottom center of the dust cup 501.

  When the electric blower 106 is operated, the air flow flows into the dust cup 501 straight in the circumferential tangential direction through the connection portion 306 and the lateral relay duct 104 a to form a high-speed swirling air flow in the dust cup 501.

  Thereby, dust contained in the air flow is centrifuged. The dust collection unit 500 is installed so that the central axis of the swirling air flow to be formed is directed to the direction of gravity, so that among the centrifugally separated dust, heavy dust is collected below the flange portion 535a by the action of gravity. .

  Here, the central axis of the swirling air flow of the dust collection unit 500 does not have to point in the direction of gravity if the central axis of the swirling air flow does not have to point directly below, and the dust collection unit 500 is vertically aligned with the cleaner body 100A. It should just be arrange | positioned.

  The lighter ones are filtered together with the air flow by means of a mesh filter arranged at the outlet 533b. In addition, fine dusts rise through the inner cylinder 533 via the outlet 533 b and are filtered by the filter unit 550. The filter unit 550 is composed of a pleated filter in which peaks and valleys are continuous. The filtered air flow is drawn into the electric blower 106 through the outlet duct 571.

  In addition, although the dust collection unit 500 centrifuges and collects dust, it is not limited to this. For example, dust may be collected using a paper pack.

In the state of being pulled forward by the suction hose 301, the pair of wheels 140 is supported by the wheel body 110 and the front wheel 117. That is, the center-of-gravity position of the cleaner body 100A is set so as to be in such a state. In this way, it is possible to improve the over-stepping performance while suppressing the lifting of the front side of the cleaner body 100A.

  FIG. 17 is an explanatory view showing the flow path of the air flow in the cleaner body 100A shown in FIG. As shown in FIG. 17, the air flow from the suction hose 301 flows over the electric blower 106 through the connection portion 306 and flows into the dust collection unit 500.

  The inflowing air flow is swirled in the dust cup 501 of the dust collection unit 500. Then, after centrifugal separation of dust collection is performed, the air flow ascends inside the inner cylinder 533, passes through the filter unit 550, passes through the electric blower 106, and flows to the lower flow path 138 below the dust collection unit 500. enter. The pivot axis is slightly inclined upward to the rear with respect to the vertical direction. When viewed from the side as shown in FIG. 17, the flow path flowing into the dust cup 501 from the connection portion 306 is substantially orthogonal to the pivot axis.

Then, after the air flow passes through the lower flow passage 138 while cooling the circuit boards K ₁ and K ₂ , a part of the air flow flows into the first rear flow passage 139 a of the rear flow passage 139 and the storage battery B It cools and exhausts from the exhaust port 133 to the outside. On the other hand, the remaining part of the air flow having passed through the lower flow passage 138 flows into the second rear flow passage 139 b and is discharged to the outside from the exhaust port 133. At this time, a part of the air flow passing through the second rear flow passage 139b flows into the area surrounded by the surrounding wall 101c ₃ (see FIG. 13), and the ions generated with the ion generator P are ionized. It discharges from the discharge port 134 (refer FIG. 5) outside. Ions are not released to the outside by a large amount of air flow from the rear flow path 139, and a small amount of air flow limited to the area surrounded by the surrounding wall 101c ₃ causes high concentration ions to be output from the ion discharge port 134. Released into

In addition, the noise that tries to get out of the air flow from the electric blower 106 is attenuated by the long lower flow path 138 below the dust collection unit 500 and the circuit boards K ₁ and K in the lower flow path 138. ₂ and are dispersed and absorbed by obstacles such as the storage battery B in the rear flow passage 139, the connector terminal unit C, and the ion generator P. By this, the noise of the electric blower 106 which comes out of the cleaner body 100A is effectively reduced.

  Further, as shown in FIG. 17, the flow path of the air flow is provided separately in the upper part and the lower part of the cleaner body 100A, and is not provided in the side part, so the width of the cleaner body 100A is minimized. ing.

In the first embodiment, the case where the circuit boards K ₁ and K ₂ and the storage battery B are entirely housed inside the exhaust flow path is exemplified, but the present invention is not limited to this. For example, a part of the circuit boards K ₁ and K ₂ and the storage battery B may constitute a wall portion of the exhaust flow path, and the remaining portion thereof may be disposed outside the exhaust flow path.

Second Embodiment
FIG. 18 is an explanatory view showing the flow path of the air flow in the cleaner body 100B of the second embodiment. In FIG. 18, the same components as those in FIG. 17 are denoted by the same reference numerals.

The cleaner body of the _second embodiment is the cleaner body of the first embodiment except that the storage battery B is disposed in the lower flow passage 138 and the circuit boards K ₁ and K ₂ are disposed in the rear passage 139. It is similar to 100A.

In this way, since the storage battery B is cooled on the upstream side of the circuit boards K ₁ and K ₂ , the cooling effect of the storage battery B can be enhanced, and the cleaner body 100 B has a low center of gravity and the vehicle is running. Stability is improved.
