DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner provided with a centrifugal dust collecting device above a suction tool.

[0002]

2. Description of the Related Art Conventionally, there is a vacuum cleaner for wet dust as shown in FIG. In this vacuum cleaner, dust sucked by a floor nozzle 1 as a suction tool is accumulated in a dust collecting chamber of a cleaner body 4 via an extension pipe 2 and a bellows hose 3.

As shown in FIG. 6, in an upright type vacuum cleaner in which a cleaner main body 12 is rotatably attached to a part of a floor nozzle 11, a collection of the floor nozzle 11 and the cleaner main body 12 is provided. The dust chamber is connected by a bellows hose 13 or the like, and dust is accumulated in the dust collecting chamber of the cleaner body 12.

However, in this type of vacuum cleaner, when sucking wet refuse or mud, the refuse adheres to the extension pipe 2 or the inner walls of the bellows hoses 3, 13 and after the operation is stopped, the mud drips on the floor. Or water leaks from the seam along the way.

As a vacuum cleaner to cope with this, FIGS.
As shown in FIG. 9, in addition to a filter-type dust collector 22 provided in a cleaner body 21, a cylindrical centrifugal-type dust collector 23 is detachably provided above a floor nozzle 24 as a suction tool. There is something. Suction port 24 of floor nozzle 24
a, a rotating brush 25 for scraping up dust is rotatably provided by a driving means (not shown).
The suction port 24 a of the centrifugal force type dust collecting device 23 is communicated with a peripheral portion of a cylindrical dust collecting portion 26 through a dust collecting tube 27. At the center of the cylindrical dust collecting portion 26 of the centrifugal dust collecting device 23, a suction pipe 28 to the cleaner main body 21 side is protruded and opened substantially upward. The suction pipe 28 is a suction connection pipe 29
Is connected to the mounting portion of the filter 30 in the cleaner main body 21 via the. In addition, 31 is an electric blower built in the cleaner body 21.

In this configuration, the electric blower 31 is operated to generate a suction force and rotate the rotating brush 25. Then, dust and muddy water are collected by the dust collecting tube 27 by the suction force of the electric blower 31 and the scraping force of the rotating brush 25.
The dust and muddy water are conveyed into the centrifugal dust collecting device 23 through the inside, and rotate along the inner wall of the cylindrical dust collecting portion 26 in the centrifugal dust collecting device 23. At this time, relatively heavy dirt, muddy water and the like fall by the gravity of the cylindrical dust collecting portion 26 and fall to the bottom of the cylindrical dust collecting portion 26 by the action of the centrifugal force, and are accumulated. On the other hand, light dust has a stronger suction force to the suction pipe 28 than the centrifugal force, and is sucked into the suction pipe 28 to be collected by the filter 30 of the cleaner body 21.

As described above, muddy water and relatively heavy dust are collected in the centrifugal dust collector 23, and light dust such as fine powder is stored in the filter dust collector 22, so that even if wet dust is sucked, the dust is clogged. Without this, the initial performance can be maintained for a long time. In addition, a cylindrical dust collecting section 26 is provided immediately above the floor nozzle 24.
Is provided, adhesion of dirt and the like to the passage is reduced, and sewage or the like does not drop on the floor after the operation is completed.

[0008]

However, the centrifugal dust collecting device 2 is provided above the floor nozzle 24 as a suction device.
In the conventional vacuum cleaner provided with 3, there is a problem that the entire centrifugal dust collector 23 must be removed when the refuse collected in the centrifugal dust collector 23 is discarded, which is inconvenient. Was.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide an easy-to-use vacuum cleaner provided with a centrifugal dust collecting device above a suction tool.

[0010]

In order to solve the above problems, a vacuum cleaner according to the present invention is connected to a cleaner body having an electric blower and a filter type dust collector via a connecting pipe. A substantially cylindrical centrifugal dust collecting device is directly provided on the sucking device, and a suction port of the suction device is provided around a cylindrical dust collecting portion of the centrifugal dust collecting device. Is communicated via a dust collection tube, and the connection tube is provided at the center of the cylindrical dust collection portion so as to protrude so as to open substantially upward, and is detachably provided outside a circumferential portion of the cylindrical dust collection portion. Is provided, and the collecting chamber is provided with respect to the cylindrical dust collecting section.
Through the holes formed in the
Structured to be held by ribs integrally formed on the periphery
It is characterized by having been done.

By the above means, muddy water and relatively heavy garbage
Collect in the centrifugal dust collector installed directly on the suction device
So that even if you inhale wet garbage
Clogging in the dust device is unlikely to occur, and after operation
When disposing of accumulated garbage, etc., without dripping sewage
Also, it is only necessary to remove the collection chamber, so that the usability is improved.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. In the following embodiment,
Only the part of the centrifugal dust collector that differs from the conventional vacuum cleaner in which the centrifugal dust collector is provided on the upper part of the suction tool is the same as that of the conventional vacuum cleaner. The description is omitted here.

As shown in FIGS. 1 to 3, a collecting chamber 52 as shown in FIG. 2 is provided at a part of the circumference of a cylindrical dust collecting portion 51 in the centrifugal dust collecting device 50 of the vacuum cleaner. Are provided detachably. Reference numeral 53 denotes a hole formed in the collecting chamber 52, and reference numeral 54 denotes a hole formed in the cylindrical dust collecting section 51. The collecting chamber 52 is connected to the cylindrical dust collecting section 5 through these holes 53 and 54.
It is connected to 1. Reference numeral 55 denotes a rib integrally formed on the circumferential portion of the cylindrical dust collecting portion 51 so as to be able to hold the collecting chamber 52. Arrows in FIGS. 4 and 5 indicate flows of wind and dust.

In the above configuration, dust sucked from the suction port 24a of the floor nozzle (suction unit) 24 rotates along the inner wall of the cylindrical dust collecting portion 51. At this time, relatively heavy dirt and muddy water are collected by the cylindrical dust collecting section 5 by centrifugal force.
1 through the holes 53 and 54 while rotating around the periphery of the collection chamber 5.
Go into 2. In addition, light refuse is collected by the filter 30 of the vacuum cleaner main body 21 as before.

When discarding the refuse collected in the centrifugal dust collector 50, it is only necessary to remove the small collecting chamber 52.
Easy garbage disposal.

[0016]

As described above, according to the present invention, by providing a detachable collecting chamber at a part of the circumferential portion of the centrifugal dust collecting apparatus, refuse disposal can be easily performed and usability is improved. I do.
