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 wet vacuum cleaner capable of easily processing collected dust.

[0002]

2. Description of the Related Art In general, a dry vacuum cleaner that collects dust with a filter such as paper or non-woven fabric is passed through water previously put in a water pan (water dish) through suction air containing the sucked dust. BACKGROUND ART A wet vacuum cleaner for collecting dust is known. This wet-type vacuum cleaner does not cause local filter clogging unlike a dry-type vacuum cleaner, and can theoretically collect fine dust.

[0003] However, dust to be collected generally has a size and a weight, and a wet vacuum cleaner which is originally effective for fine dust is limited to a limited amount of water in a water pan. On the other hand, if dust of any form and weight is inhaled, lint and cotton dust will float on the water surface in the water pan, sand and soil will settle at the bottom, and general dust will float in the water. And the behavior of water as a dust collection medium is likely to be reduced. In particular, in principle, dust containing water is smashed on the water surface of the dust catching water to catch dust. Not only does it impair the fluidity of the dust but lowers the dust-collecting ability, but when the collected dust is discarded, it contains a large amount of water, so the separation of water is necessary, and there is a drawback that the waste disposal work is troublesome. .

Heretofore, a wet-type vacuum cleaner has been proposed in which the above-mentioned drawbacks have been eliminated and dust is collected through suction air containing suctioned dust in dust-collecting water previously placed in a substantially cylindrical water pan. In the vicinity of the outer periphery of the inner side of the pan, a dust catching net including an inlet and a net portion is detachably attached to the water pan, and the intake air generates a flow of dust passing through the dust catching net. The following is known (Japanese Utility Model Laid-Open No. 4-36954). This vacuum cleaner
Since the dust catching net is disposed from the bottom of the water pan to a position higher than the level of the dust catching water in the water pan when the vacuum cleaner is stopped, the operation of the vacuum cleaner makes the water pan. Even in a state where the level of the dust catching water near the outer periphery of the inside is high, most of the dust in the dust catching water can be collected by the dust catching net.

[0005]

By the way, in the vacuum cleaner having the above-mentioned dust catching net, when removing the dust catching net from the water pan in order to discard the collected dust,
Since the dust in the dust catcher is immersed in the dust catching water, handling of the removed dust catcher and removal of dust from the dust catcher becomes troublesome. The present invention has been made in view of the above points, and an object of the present invention is to provide a vacuum cleaner that facilitates trash disposal.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a vacuum cleaner according to the present invention is characterized in that suction air containing suctioned dust is passed through dust-collecting water previously placed in a substantially cylindrical water pan. What is claimed is: 1. A wet vacuum cleaner for collecting dust, wherein a dust catching net including an inlet and a net portion is detachably attached to the water pan near an inner periphery of the water pan, and the dust is collected by the suction. In the apparatus for generating a flow of water passing through the dust catching net, the dust catching net is disposed only at a position higher than the level of the dust catching water in the water pan when the vacuum cleaner is stopped. It is characterized by the following.

[0007]

In the wet vacuum cleaner constructed as described above,
Among the sucked dust, dust floating in the dust catching water, such as hair dust and cotton dust, is caused to rotate together with the dust catching water in the substantially cylindrical water pan by the intake of the electric blower.
At this time, at the same time as the outer peripheral water level of the water pan rises, the floating dust moves to the outer peripheral side due to centrifugal force, enters with the water from the water inlet, and is caught by the dust catcher. When the use of the vacuum cleaner is stopped, the outer water level of the water pan falls, so that both the water inlet and the net part come out of the water, and only the floating dust is left behind in the dust catching net, and draining is performed by its own weight. .

[0008]

1 and 2 show an embodiment of the present invention.
Will be described. FIG. 1A is a schematic sectional view of a main body of a wet-type vacuum cleaner according to the present invention, in which an upper case 2 in which an electric blower 1 is provided, a substantially cylindrical water pan (water tray) 3 and the water pan 3. It is constituted by an upper lid 4.
The upper case 2, the upper lid 4 and the water pan 3 are assembled in a watertight manner by the clamp 5. The water pan 3 is provided with a suction port 6 for introducing dust-containing intake air from a suction port body (not shown) with its discharge port 7 facing one direction of the inner wall circumference of the water pan 3 ( 1 (b), and an outlet 8 is provided at the center of the upper lid 4 to reach the electric blower 1.

When this vacuum cleaner is used, water 9 for collecting dust is charged to a designated water level of the water pan 3, and a dust catching net 10 is attached to an inner wall of the water pan. The dust catching net 10 is composed of a water inlet 11 and a net portion 12 and is integrally formed of resin or the like, and can be detachably attached to the inner wall rib 13 of the water pan 3. When the electric blower 1 of the vacuum cleaner is stopped, the dust catching net 10 is attached to a position where the dust collecting net 10 is entirely exposed to the air as shown in FIG. However, when the electric blower 1 operates, the water pan 3
Since the dust collecting water 9 is forced to rotate by the intake air containing dust, the outer peripheral water level of the dust collecting water 9 rises as shown by a two-dot chain line in FIG. The 10 water inlets 11 open the outer surface of the dust catching water 9.

FIG. 1B shows the flow of intake air (dotted arrow) and the movement of the dust catching water 9 (solid arrow) during operation of the electric blower 1 as viewed from above. At this time, the intake air containing dust reaches the discharge port 7 from the suction port 6 and is struck by the dust catching water 9 so as to pass through, so that relatively light dust such as lint and cotton dust is removed from the dust catching water. 9, gradually move to the outer peripheral side by centrifugal force, and then enter with the surrounding water from the water inlet 11 of the dust catching net 10 to enter the net portion 1.
2 is stored. Thereafter, the electric blower 1 is stopped to expose the dust catching net 10 to the air. If the dust catching net 10 is left for a while in this state, the water contained in the dust in the dust catching net 10 will lose its own weight. Drip with. For this reason, it is possible to easily dispose of the dust collecting net 10 from the water pan 3 without scattering only the slightly moist floating dust in the dust collecting net 10 without scattering.

[0011]

As described above, the present invention relates to a wet-type vacuum cleaner in which dust is sucked into dust-collecting water 9 previously placed in a substantially cylindrical water pan 3 through suction air containing dust. In the vicinity of the outer periphery of the inside of the water pan 3, a dust catching net 10 including a water inlet 11 and a net portion 12 is detachably attached to the water pan 3, and the dust catching net 9 is attached to the dust catching water 9 by the suction. Since the dust catching net 10 is arranged only at a position higher than the water level of the dust catching water 9 in the water pan 3 when the electric vacuum cleaner is stopped, the electric cleaning is performed. When the machine is stopped, the dust catching net 10 is exposed from the dust catching water 9, and the water contained in the dust catching net 10 drips under its own weight.
The dust that has entered becomes dry, facilitating treatment when the dust is discarded.
