DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a vacuum cleaner,
The present invention relates 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 of paper, nonwoven fabric, or the like, captures dust that has been sucked into water that has been put in a water pan (water tray) in advance. 2. Description of the Related Art A wet vacuum cleaner that generates 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, since the collected dust is generally captured by the water for dust previously stored in the water pan, it is necessary to clean the water pan each time the cleaner is used. . By the way, at the time of cleaning this water pan, if the dust-collecting water is allowed to flow into the sewage as it is, it will cause clogging of the sewage, so that it is necessary to separate the collected dust from the sewage, and it takes considerable time after cleaning. There is.

In general, this type of wet vacuum cleaner has a water reservoir at the bottom and a main body including a fan motor at the upper part, and it is necessary to remove and attach a heavy main body every time dust collection is performed. 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.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a vacuum cleaner according to the present invention captures dust by suctioning dust-containing water into a substantially cylindrical water pan in advance. In a dusty wet vacuum cleaner, an openable and closable drain port is provided at the bottom of the water pan, and an openable and closable water supply port on an upper wall surface of the water pan, and a connection means for connecting a hose to the water supply port. The water supplied from the water supply port is provided so as to flow along the circumferential direction of the inner wall of the water pan. Further, mounting means for detachably mounting the dust catching net may be provided so as to cover the drain port from outside the water pan.

[0006]

In the wet vacuum cleaner constructed as described above, after use of the vacuum cleaner (after completion of cleaning), the water pan of the water pan is connected to the openable and closable drain provided at the bottom of the water pan. A dust catcher is put on from the outside, and then the drainage port is opened to discharge dust catching water including dust collection. After this, the hose connected to the water tap was directly connected to the water supply port arranged on the upper wall, and the tap water was poured,
Dust remaining in the water pan is pushed out to the drain by the flow of tap water, and the collected dust can be separated and collected by the dust catching net of the drain.

1 and 2 show an embodiment of the present invention.
Will be described. FIG. 1 is a schematic partially cutaway sectional view of a wet-type vacuum cleaner according to the present invention, and FIG. 2 is a schematic plan view near a water pan (water tray) with an upper lid described below removed. This vacuum cleaner includes an upper case 2 in which an electric blower 1 is provided, a substantially cylindrical water pan 3, and an upper lid 4 of the water pan 3. 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 directed in one direction around the inner wall of the water pan 3. An exhaust port 8 is provided at the center of the upper lid 4 to reach the electric blower 1.

At the center of the bottom of the water pan 3 is provided a protruding water level gauge 10 serving as a reference for setting the water level of the dust catching water 9. An openable water supply port 11 and a hose connection section 12 are provided on a side wall surface of the water pan 3 having a height corresponding to the level of the dust catching water 9, and a drain port 13 is provided at the bottom of the water pan 3. Has been established. The direction of disposing the water supply port 11 is along the circumferential direction of the inner wall of the water pan 3, and is oriented so as to cause the running water to rotate in the water pan 3. A guide groove 14 for guiding water to the drain 13 along the circumferential direction is provided at the bottom of the water pan 3.
When water is poured into the water pan 3, an appropriate rubber stopper (not shown) is inserted into the drain port 13 from below the water pan.

The outlet 13 of the water pan 3
Is slightly projected below the bottom surface of the water pan 3. The protruding portions are angular, and the parallel straight portions are provided with grooves 15 respectively. 1
Reference numeral 6 denotes a flexible dust catching net.
A convex shape that can be fitted into the groove 15 is provided.

After using the vacuum cleaner (after cleaning),
In a drainage place such as a bathroom, the convex shape of the frame portion 17 of the dust catching net 16 is fitted into the groove 15 provided at the bottom of the water pan 3 as it is, and Cover the drain 13. Thereafter, the rubber stopper is grasped by hand through the dust catcher 16 and the rubber stopper is removed. Thereby, the dust-collecting water 9 containing the dust is discharged.

Thereafter, a hose joint 19 at the tip of a water supply hose 18 connected to a water tap is connected to a hose connection portion 12 provided at the water supply end of the water supply port 11 provided on the upper wall surface of the water pan 3. When the water is poured, the valve body 20 temporarily provided by the elasticity of the water supply port 11 is opened by the water pressure, and the dust remaining in the water pan 3 is pushed out to the drain port 13 by the running water of the tap water. The collected dust can be separated and collected by the dust catching net 16 covered with the dust. At this time, the valve body 20
Serves as a water flow guide that gives direction to incoming tap water. The separated and collected dust is drained appropriately, and is not scattered if discarded. When the vacuum cleaner is used again, after cleaning the water pan 3 as described above, the dust catcher 16 is removed, the drain port 13 is closed with a rubber stopper, and the drain port is closed. If water is continuously supplied from the water supply port 11, clean dust catching water 9 can be supplemented.
Note that the arrows in FIG. 2 indicate the rotation direction of the dust catching water 9 during use of the vacuum cleaner and the flowing direction of tap water supplied when the water pan 3 is cleaned.

In the above embodiment, the convex shape of the frame portion 17 of the dust catching net 16 is fitted into the groove 15 and the dust catching net is attached to the water pan 3. However, a suction cup may be provided in the frame portion 17 without providing the groove 15 and the like, and the dust catching net 16 may be attached to the water pan 3 by the suction cup. Also,
The above-mentioned protruding portion slightly protruding below the bottom surface of the water pan 3 may protrude somewhat more, and a dust catching net may be attached to the protruding portion by a rubber band or the like. By attaching a string to the rubber stopper, the rubber stopper can be easily removed.

[0013]

Since the present invention is constructed as described above, it does not require a filter pack as a consumable item like a general vacuum cleaner, and also causes local filter clogging. With the simple structure and without attaching and detaching the heavy body, the cleaning of the water pan, which is more troublesome than before, can be performed easily while maintaining the features of the conventional wet vacuum cleaner without the above. Further, since the collected dust can be separated and collected, there is no problem of clogging of sewage or the like.
