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.

[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 used to catch dust through water contained in a water pan (water tray) containing suctioned dust. A wet vacuum cleaner as shown in FIG. 3 is known. Unlike a dry vacuum cleaner, this wet vacuum cleaner does not cause extreme clogging of the filter, and can theoretically collect fine dust. In FIG. 3, reference numeral 1 denotes a main body case, in which a suction motor 4 is provided, and a centrifugal fan 5 and a water separator 7 are fixed to a shaft of the motor 4. Numeral 8 indicates an air route.

When the motor 4 is operated by an operation power supply unit (not shown), the intake air containing dust sucked from an intake hose (not shown) passes through the intake port 6, passes through the introduction unit 10, and enters the water pan 2. Is discharged. Dust water 3 is previously contained in the water pan 2, and dust contained in the intake air is collected. The intake air leaving dust in the water 3 passes through the slit of the rotating water separator 7 and is exhausted from the exhaust port 9 by the centrifugal fan 5. In the vacuum cleaner shown in FIG. 3, the dust-containing intake air is discharged into the water in the water pan 2. However, as a conventional wet-type vacuum cleaner, the dust-containing intake air is hit on the water surface in the water pan. Some release to

[0004]

In the conventional wet vacuum cleaner described above, relatively heavy dust contained in the intake air comes into contact with water and is easily caught in the water, but light floating dust is described with reference to FIG. Even those that are configured to be released into water float in large bubbles of intake air and are difficult to contact with water, so they are easily collected and discharged. The present invention eliminates the above-mentioned drawbacks of the conventional wet-type vacuum cleaner, and is capable of sufficiently collecting light floating dust.

[0005]

In order to achieve the above object, a vacuum cleaner according to the present invention is a wet vacuum cleaner that captures dust through suction air containing suctioned dust in water previously contained in a water pan. A rotating body rotated by rotation of a suction motor, and a rotor provided on the water pan, wherein the rotor and the rotating body are magnetically coupled, and the rotation of the suction motor causes the rotation. The child is configured to be rotated.

[0006]

In the wet vacuum cleaner constructed as described above, the rotor is rotated by the rotation of the suction motor, and the water in the water pan rotates. Due to the rotation of the water, the intake air containing dust is diffused and mixed into the water, and the air bubbles caused by the intake air become fine.

FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a schematic sectional view of a main portion mainly showing a portion related to the present invention of a wet-type vacuum cleaner, and the same reference numerals as those in FIG. 3 indicate the same portions. Parts not shown are configured similarly to FIG. FIG. 2 is a plan view of a main part of FIG. In FIG. 1, reference numeral 11 denotes a conventionally used water level pin, which is integrally formed with the water pan 2 and serves as a measure of the amount of water when the dust collecting water 3 is put into the water pan 2. Reference numeral 12 denotes a rotor, which is provided rotatably about the water level pin 11. As shown in FIG. 2, the rotor 12 is provided with a magnet 13 having the same polarity facing the upper surface at an upper portion thereof.
Further, it has four arms 14 having a circular cross section.

When this vacuum cleaner is used, after water 3 for dust collection is put into the water pan 2 with the water level pin 11 as a guide, the center of the rotor 12 is put on the water level pin 11, and The main body case 1 including the motor 4 described in FIG. Thus, the rotor 12 is also set at the center. A magnet 15 for guiding rotation of the rotor 12 is disposed on the lower surface of the water separator 7. When the motor 4 is operated, the magnet 15 rotates, and the rotor 12 having the magnet 13 rotates. Is done. The rotation of the rotor 12 is desirably designed to rotate at about 50 to 200 rpm during use, taking into account its own weight and the resistance of the water 3 due to the arms 14.

In the vacuum cleaner constructed as described above,
The water 3 for dust collection is rotated by the rotor 12 into a circular water pan 2.
The dust is forcibly rotated inside and the dust tends to accumulate on the outer periphery. The arm 14 of the rotator 12 crosses the introduction portion 10 following the intake port 6 due to the rotation thereof, and the intake water 3 and the intake air containing dust are diffused and mixed. The bubbles are subdivided by this diffusion and mixing, and the contact efficiency of the light floating dust in the bubbles with the water 3 can be increased, so that the dust collecting effect is improved. Water pan 2 is water 3
In order to see the dirt (the amount of dust), it is usually transparent, so that the rotation of the rotor 12 can also be seen. If the water 3 becomes dirty, the rotation of the rotor 12 becomes slow because the viscosity of the water 3 increases. Therefore, the contamination of the water 3 can be grasped by the rotation of the rotor 12. Conventionally, the water 3 was replaced based on the abstract judgment of water contamination.
The water 3 can be accurately exchanged by grasping with the rotation of.

In the above embodiment, the number of the arm portions 14 of the rotor 12 is four, but the number is not limited to four. The number of the arms 14 is desirably two to four. In the above embodiment, the magnets 15 and 1 are provided in both the water separator 7 and the rotor 12.
Although 3 is provided, one of them may be a magnetic material that is not magnetic. In the above embodiment, the magnet 15 is provided on the water separator 7 rotated by the motor 4, but the magnet 15 may be provided on another rotating body rotated by the motor. still,
Since the rotor 12 can be easily attached and detached, cleaning is also easy.

[0011]

Since the present invention is configured as described above, it is possible to efficiently collect light airborne dust with a simple configuration, and more specifically to the degree of contamination of the water for dust collection. You can figure out.
