[0003]

Conventionally, as described above, the suction port for the first and second dust collecting sections and the connection port for connecting the second and third dust collecting sections to the third dust collecting section have been described. The filter is installed at almost the same height and the filter is mounted on the second dust collecting part side of the connection port from the second dust collecting part to the third dust collecting part. There was a problem that the covering ability and the suction ability were reduced, and sufficient cleaning could not be performed. The present invention has been made to solve the above-mentioned problems.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a rotating brush disposed at a lower portion of a vehicle body and rotating in a direction perpendicular to a traveling road surface. In an automatic cleaner for cleaning a traveling road surface by sucking into a dust collecting portion and a third dust collecting portion, a suction port from the first dust collecting portion to the second dust collecting portion and a third dust collecting portion from the second dust collecting portion. The position of the connection port to the first dust collection section is located above the connection port from the second dust collection section to the third dust collection section, and is disposed in the vehicle body, and the lower portion of the suction port from the first dust collection section to the second dust collection section A configuration is provided in the second dust collecting section, wherein a partition plate connecting the second dust collecting section and a lower portion of a connection port from the second dust collecting section to the third dust collecting section is provided, thereby solving the above-described problem.

[0005]

With the provision of the partition plate, dust can be collected without any obstacle in the third dust collecting portion, and in the case of large dust, the wall below the connection port between the second dust collecting portion and the third dust collecting portion. In doing so
The dust falls from the top of the partition plate into the second dust collecting section, and large garbage does not block the connection port.
In addition, since the large dust is not sucked into the third dust collecting portion, the number of times of replacing the paper pack filter used as the third dust collecting portion is reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG.
FIG. 1 is a side view of an automatic cleaner used in the present invention, 1 is a main body of the automatic cleaner, 2 is a body of the automatic cleaner 1, and 3 is a body 2
A rotating brush provided in a lower portion of the rotating brush and rotating in a direction perpendicular to a traveling road surface, a first dust collecting portion covering a rotating brush and having a discharge port formed at an upper portion; A second dust collecting unit 8 connected to the outlet 5 of the dust collecting unit 4 by a hose 7;
Is a suction port of the second dust collection section 6 connected to the discharge port 5 of the first dust collection section 4 by a hose 7, and 9 is a second collection section formed slightly above the suction port of the second dust collection section 6. The first connection port 10 of the dust section 6 is a third dust collection section connected to the first connection port 9 of the second dust collection section 6 through a hose 11, and the first connection section 12 is a first connection of the second dust collection section 6. Mouth 9
Of the third dust collection unit 10 connected to the
The connection port 13 is a partition plate having a width smaller than the entire width of the second dust collecting portion 6 as shown in FIG. It is fixed to the lower part of one connection port 9.

[0007]

As described above, the present invention relates to an automatic cleaner provided on the lower side of a vehicle, which is provided on a rotating brush side in a vacuum cleaner for cleaning a traveling road surface with a rotating brush rotating in a direction perpendicular to the traveling road surface. (2) The third dust collector connected to the vacuum motor and the third dust collector, and the connection port between the second dust collector and the third dust collector is located above the suction port of the second dust collector in the vehicle body. By arranging and fixing the partition plate to the lower portion of the suction port, the lower portion of the first connection port, and the lower portion of the first connection port of the second dust collection section, the second collection section has a second collection section. The air flow from the suction port of the dust section toward the connection port to the third dust collection section is formed without disturbance, so that the light-weight trash stored in the second dust collection section is prevented from rising, and the third dust collection section has Small and light garbage is collected without any obstacles. The frequency of replacement of the Iruta is reduced.

Claims (1)

(57) [Claims] 1. A rotating brush disposed at a lower portion of a vehicle body and rotating in a direction perpendicular to a traveling road surface, sweeps up dust to a first dust collecting portion, and removes light dust to a second dust collecting portion and a third dust collecting portion.
In an automatic vacuum cleaner that cleans a traveling road surface by sucking into a dust collecting section, positions of a suction port from a first dust collecting section to a second dust collecting section and a connection port from a second dust collecting section to a third dust collecting section. The connection is established in the vehicle body with the connection port from the second dust collection section to the third dust collection section facing upward, and the lower portion of the suction port from the first dust collection section to the second dust collection section and the second collection section. An automatic cleaner in which a partition plate having a narrower width than the entire width of the second dust collecting portion, which connects the lower portion of a connection port from the dust portion to the third dust collecting portion, is provided in the second dust collecting portion.
