Abstract

PROBLEM TO BE SOLVED: To enhance efficiency to separate water from air and to catch dust in water by means of a vortex generated when air including dust and water collides with a wave resistance wall by providing the wave resistance wall between an intake port in a water tank and a separator. SOLUTION: The water resistance wall 13 is arranged to be connected or adjacent to the bottom part and the upper part of the water tank 3. Then, a splash scattered when air including dust is hit against a water surface from the sucking port 11 is prevented from being directly spattered on the separator 10, an effect to suppress the generation of large wave on a water surface (c) just under the separator 10 is obtained and water is hardly stuck to the separator 10 so that an effect to separate water from air is enhanced. Besides, an effect to catch a lot of dust in water by the vortex (d) generated when the water in the water tank 3 and air including sucked dust collide with the wave resistance wall 13 is obtained, a plurality of projections are arranged in the neighborhood of the wall 13 to divide the vortex into the small ones, and then, a catching effect is enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric blower and a detachable water tank housed in a main body case, and blows air containing sucked dust into water previously contained in the water tank. The present invention relates to a water filter type vacuum cleaner having a structure in which the dust is captured by water, and water and air are separated and exhausted by a separator.

[0002]

2. Description of the Related Art In a water filter type vacuum cleaner of this type, an appropriate amount of water, which has been drawn in according to a water level guide in a water tank, is supplied to an air blower to drive the electric blower. When the dust-laden air is hit against water and the dust is captured by the water, the scattered water droplets b fall on the separator, so that water and air cannot often be separated, and water is mixed in the exhaust. Would. Therefore, the suction force cannot be increased. Also, not all of the dust contained in the sucked air comes into contact with water and is trapped, and there are not a few dusts that pass through the separator directly and are exhausted without touching water. for that reason,
The amount of dust mixed in the exhaust gas is larger than that of the dry paper or cloth filter type vacuum cleaner. As a means for solving this, there is Patent No. 2642665, in which a fine filter is arranged between the separator and the water surface, and water droplets accumulated in the fine filter are sucked again by the suction force of the electric blower. I am worried. In addition, there remains a problem that the fine filter is clogged and that it is troublesome to remove dust such as lint entangled in the fine filter.

[0003]

When the air containing the sucked dust is slammed against water previously contained in the water tank 3 and the dust is captured by the water, the scattered water droplets b are caught on the separator. Often, air and water cannot be separated. In addition, a part of the air containing the sucked dust passes directly through the separator without passing the water, passes through the electric blower, and is exhausted from the exhaust port. Rather, it is a problem to remove a defect in which the amount of dust mixed into the exhaust gas is large.

[0004]

Means for Solving the Problems When the air containing the sucked dust is hit against water previously put in the water tank 3 and the dust is captured by the water, the splashed water droplets b are deposited on the separator 10. By providing a break wall 13 as shown in FIG. 2 between the intake port 11 and the separator 10 in order to prevent the water from being directly applied, the efficiency of separating water and air by the separator 10 can be increased. . In addition, since the water near the inlet 11 is swirled by the wave preventing wall 13 and the air containing the sucked dust becomes small bubbles, it is expected that more dust is captured.

[0005] By making the breakwater wall 13 detachable, the washing of the breakwater wall 13 and the water tank 3 becomes easy.

Further, by providing a plurality of projections 14 around the breakwater wall 13, when a vortex f is generated in the water near the intake port 11, the air including the sucked dust is further divided into small bubbles. Therefore, it can be expected that more garbage will be captured.

[0007]

[Effect of the present invention] In a water filter type vacuum cleaner,
By providing the breakwater wall 13 of the present invention between the intake port 11 and the separator 10 in the water tank 3, the efficiency of separating water and air is increased, and the water and air containing dust is further reduced on the breakwater wall 13. The vortex generated when hitting the breakwater wall 13 enhances the efficiency of capturing dust in water.

[0008]

[Embodiment of the present invention] Water containing dust is scattered when the air containing dust is slammed from the intake port 11 to the water surface by connecting or disposing the breakwater wall 13 at the bottom and top of the water tank 3. b has an effect of preventing a large wave from rising on the water surface c directly below the separator 10 at the same time as preventing the separator 10 from directly hanging on the separator 10.
Since water is less likely to adhere to water, the efficiency of separating water and air can be further increased. In addition, the vortex d generated when the water containing the water in the water tank 3 and the air containing the sucked dust collides with the breakwater wall 13 has an effect of capturing a lot of dust in the water. By providing a plurality of protrusions 14 as shown in FIG. 4, the vortex f is further divided and the efficiency of capturing dust in water is increased. The water barrier 3 and the water barrier 13 can be easily cleaned by making the water barrier 3 easily removable and provided with a positioning guide 15 as shown in FIG.
