A wall formed to divide a main body 100 equipped with a suction hose 130 so as to be injected into the main body, and a space disposed in the main body, partially submerged in water, and where air or air containing dirt collides with the water and is filtered ( 200), and a cover having a horizontal cross-sectional size larger than the horizontal cross-sectional size of the wall, disposed on the upper side of the wall at a certain distance from the wall, and guiding the mixture of air and water containing air or dirt to the intended flow (300), coupled to the lower end of the cover, the center is formed so that the wall is accommodated at a predetermined distance, and has an inclined trough to accommodate water and dirt in the mixture of air and water and flow well, Formed around the end, the gutter 410 is inclined from an arbitrary highest point to both sides and formed lowest on the opposite side, and has a drain hole 420 of a certain size at the lowest gutter portion. And, it consists of a strainer 440 hanging by surrounding a plurality of attachment protrusions 430 formed on the outside of the drain hole 420 of the water separation plate.

Specifically, the main body includes a housing 110 that forms a kind of cylinder and has one side open, and a cover 120 that covers and opens and closes the open side of the housing, so that the user can easily hold it by hand. 102) is formed. The inside of the housing is filled with water to serve as a filter, and a suction hose 130 for sucking air or air containing dirt is mounted on the hose coupling part 122 formed on the cover.

An air discharge unit through which air is discharged is provided on one side of the cover. Accordingly, air sucked through the suction hose or air containing dirt is introduced into the housing 110 .

On the other hand, on the bottom of the main body, that is, the bottom of the housing, water inside the wall 200 and water outside the wall 200 circulate, and a water passage 112 is provided at the bottom of the main body so that it can continuously act as a filter. is preferably formed.

The water passage 112 is connected from the bottom of the main body outside the wall 200 to the bottom of the main body inside the wall by a gap formed below the wall, and is spaced apart from the inner side wall of the wall 200 to the main body along the inner side wall of the wall. The water passage 112 is completed by the cylindrical protrusion 116 built on the bottom of.

In particular, a plurality of water passages 112 connected from the outside of the wall 200 on the bottom of the body to the inside of the wall are formed, preferably three, so as to smoothly supply water from the outside to the inside of the wall.

And, the wall 200 according to the present invention is a component that divides a space in which a part of the wall 200 is inserted into and coupled to the bottom of the main body submerged in water, and air or air containing dirt is filtered through the water. The wall 200 is formed in the shape of a cylinder with both sides open and empty inside, and is inserted into a cylindrical groove formed lower than the bottom of the main body. The wall is then mounted.

Even if the wall is inserted into the cylindrical groove and fitted in this way, the water passage formed on the bottom of the main body outside the wall is connected to the water passage inside the wall by a gap of an appropriate size formed at the bottom of the wall inserted into and coupled to the cylindrical groove. Water on the outside of the wall can move inward.

A guide tube mounting portion 210 is formed inside the wall so that a cover 300 described below can be mounted thereon.

On the other hand, when air or air containing dirt flows into the inside of the wall through the suction hose, the air or air containing dirt flows from the inside of the wall 200 to the outside through the water passage 112 to the outside of the wall. To prevent this, a cylindrical protrusion 116 is formed from the bottom of the main body along the inner side wall of the wall at a distance from the inner side wall of the wall, and the cylindrical protrusion also serves as a water passage 112 inside the wall. has been described previously.

And, as shown in FIG. 2, the cover 300 according to the present invention has a larger horizontal cross-sectional size than the horizontal cross-sectional size of the wall 200, and is separated from the wall 200 by a certain distance from the upper side of the wall. It is disposed in the bottom side, has an inverted bowl shape so that the diameter increases toward the bottom side, and is formed in a multi-stage shape so that the diameter increases discontinuously toward the bottom side, and covers a certain portion on the wall 200, so that air or dirt is contained. The air/water mixture flows in the intended direction, and the air/water/dirt can be separated as the speed of the mixture decreases.

In addition, a guide tube is formed and opened near the center of the cover 300, and is connected to a suction hose to guide air or air containing dirt to the inside of the wall 200, and the guide tube 310 It rests on the guide tube mounting portion 210 of the wall and is coupled.

In this way, in a state where the guide tube 310 is completely coupled to the guide tube mounting portion 210, the cover 300 is disposed at a certain distance from the wall 200, and protrudes in a horizontal plane along the end of the cover 300, that is, along the outer circumferential surface. A nose separator plate 400 to be described later is coupled and mounted to the formed wing 320.

And, as shown in FIGS. 3, 5 and 6, the air separator 400 according to the present invention has an inclined trough 410 to accommodate water and dirt in a mixture of air and water so that they flow well. It is formed surrounding the end of the cover 300, but the gutter 410 is inclined to both sides from an arbitrary highest point and is lowest on the opposite side, and has a drain hole 420 of a certain size at the lowest gutter portion. A strainer 440 is suspended while surrounding the separation plate 400 and a plurality of attachment protrusions 430 formed outside the drainage hole 420 of the water separation plate.

The nose separation plate 400 is formed to be detachable and coupled to the wings 320 of the cover 300, and the center portion is made spaced apart from the wall 200 to have a ring shape as a whole.

Specifically, the outer rim of the rider plate is formed higher than the inner rim 413, and the outer rim is formed with a locking jaw 411 along the circumference so that it is well engaged with the cover, and the outer rim of the outer rim A plurality of coupling lock protrusions 412 are formed on one side of the locking jaw, so that the cover 300 and the rider separation plate 400 are coupled and fixed.

In addition, in the air separation plate, the inner rim 413 of the air separation plate 400 is the wing 320 at the lower end of the cover 300 so that water, dirt and foreign substances can be effectively accommodated while excluding air from the mixture. It is formed by entering a certain distance toward the center rather than the edge leading to .

As a result, in the air water separator of the water washing dust collector Patent No. 10-1578758, the trough 410 and the drain 420 of the first water separator plate, which were separated into four, were integrated into one, inclined, and the lowest gutter It is changed and improved to a structure having a drain hole at the site to become a separator plate 400, and a strainer 440 hanging while surrounding a plurality of attachment protrusions 430 for the strainer provided on the outside of the drain hole 420 is additionally provided. , The second water separation plate was omitted and disappeared, which slightly reduced the water separation efficiency, but compared to the loss of the water separation effect, the benefit obtained by filtering and separating the dirt and foreign matter collected in the water was slightly reduced. There are advantages to being much larger.

Hereinafter, the operation and effect of the present invention will be described with reference to FIG. 6 .

A case in which cleaning is performed using a vacuum cleaner equipped with a water separator of a water washing dust collector according to an embodiment of the present invention will be described as an example. Of the arrows shown in FIG. 6 , arrows indicated by dotted lines indicate the flow of air, and arrows indicated by solid lines indicate the flow of water. Small water particles may be included in the air or in the water depending on the situation. There will be.

First, referring to FIG. 6 , water is filled in the main body to filter air that is sucked in when cleaning with a vacuum cleaner or air containing dirt. In addition, the wall 200, along with the cover 120, is placed on top of the water passage 112 formed on the bottom of the housing 100 constituting the main body 100, particularly in the cylindrical groove. In addition, the guide tube 310 of the cover 300 is mounted on the guide tube mounting portion 210 in the wall 200 so that the cover 300 is disposed away from the wall 200 .

In this state, when the vacuum cleaner is operated after connecting the suction hose to the hose coupling part of the cover, air or air containing dirt is sucked through the suction hose by the suction force of the motor (not shown). Inhaled air or air containing dirt is introduced into the wall through the guide tube 310 .

Next, the air introduced into the wall or the air containing dirt is mixed with the water filled in the main body, especially during the initial operation, a lot of water is filled inside the wall, and a lot of water is momentarily pushed out by the sucked air. During operation, since the water level inside the main body is higher than the water level inside the wall, water is supplied to the inside of the wall through the water passage and filled in the water passage formed by the cylinder protrusion and the inner wall of the wall. It hits the floor inside and is scattered in all directions, and when it is directed upward, it sweeps the water in the water passage 112 inside the wall and moves together to become a mixture, which is mixed by the vacuum suction force of the motor (not shown). It moves along the wall surface of the wall and moves toward the cover side.

In addition, the cylindrical protrusion 116 simultaneously serves as a windbreak to prevent the air injected into the wall from colliding with the bottom surface inside the wall and scattered air from escaping to the outside of the wall through the water passage 112.

The mixture is then directed in the intended flow and flows along the inner surface of the cover.

In the process of mixing water and air and moving and flowing together as a mixture, a water filtering process in which contaminants in the air are well washed and collected in water proceeds.

Further, the cross-sectional area of the passage through which the mixture flows gradually increases as it gradually widens toward the end of the cover. Accordingly, the flow rate of the mixture gradually slows down so that the water and air start to be separated, and the water and air are better separated by the multi-stage cover.

And, as shown in FIG. 6, water and foreign substances in the guided mixture are accommodated in the gutter of the brackish separation plate 400 and flow down along the inclined gutter into the drain 420 and the sieve 440 to flow into the sieve. Particles (foreign matter) that are larger than the size of the eye are filtered out, collected and separated.

In addition, unlike the complicated internal structures of the first and second water separators before the improvement, dirt and foreign substances were caught and tangled and deposited, the gutter of the improved water separator is smooth and inclined, so there is no place for foreign substances to get caught in the water. It flows well together with foreign matter and flows into the drain, where it is filtered by the sieve.

The air introduced inside the wall or the air containing dirt and the water inside the wall are mixed together to form a mixture, and this mixture is pushed up toward the cover along the inner wall of the wall.

As a result, the water inside the wall is consumed and reduced, so the water level inside the wall is lower than the water level outside the wall. will continue to flow. As such, since the water consumed inside the wall can be supplemented by the continuously flowing water, the water filter function continuously works well.

As designed in this way, air and water containing air or filth are mixed together to form a mixture, and contaminants are collected in the water as they move and flow, and the purified air is separated from the water and discharged to the outside, and the water is recovered at the same time. In the process, the dirt and foreign substances collected in the water are filtered through the sieve and collected and separated to achieve the intended purpose.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, but should be defined by not only the claims to be described later, but also those equivalent to these claims.
