In addition, the coupling structure of the water penetration barrier wall 401 and the plotter guide 700 may be of a removable type consisting of a structure such as screw coupling or interference fit.

The water penetration barrier 401 may be shaped in the shape of various polygons in cross section when viewed in plan, or may be a shape that is open to the other side while blocking the portion of the inlet 601 which is the water splashes the most. .

4A and 4B are representative exemplary views showing a cross section of a water penetration barrier, and FIG. 4A is a water penetration barrier 401 having an arc shape in cross section among various types of polygons, and FIG. 4B is a water penetration barrier made of a circular cross section. The prevention wall 401 is shown.

Referring to the operation according to the first embodiment of the present invention configured as described above is as follows.

Dirt containing strongly sucked water and dust is subjected to cyclone rotation flow in the dust collector (300).

Among the dirt, the water flows directly in the direction of the plotter guide 700 while colliding and splashing between the flowing water or the wall surface of the inside of the dust collecting container 300 during the rapid rotational flow in the dust collecting container 300. do.

At this time, since the water flowing into the plotter guide 700 has a high impact amount and a high speed, after passing through the inlet hole 710 of the plotter guide 700, it penetrates directly into the plotter guide 700. The water discharge prevention wall 401 that surrounds the floater guide 700 is crashed and splashed as described above, and the water is changed into the floater guide 700. It will prevent it from penetrating immediately.

In this case, the air, which is relatively small in mass and does not flow with water and is rapidly sucked into the dust collector 300 and has lost centrifugal force, is sucked by the plotter guide 700 by the suction force generated from the fan / motor assembly 200. Flow toward the fan / motor assembly 200 through the first outlet (500) of the), and then is discharged to the outside through the second outlet (900) behind the main body (100).

Figure 5 shows a water cleaning combined vacuum cleaner according to a second embodiment of the present invention, Figure 5 is a longitudinal sectional view of the present invention according to the second embodiment.

That is, according to the second embodiment of the present invention, the cleaner body 100 is provided with a fan / motor assembly for generating a suction force; A dust collecting tube 300 provided inside the cleaner main body to communicate with the suction hose 600 and having various kinds of foreign substances or water collected / collected while the upper surface is opened; A cover 400 which closes the opened upper surface of the dust collecting container and has a first discharge port 500 formed therein; Opening and closing means for opening and closing the first outlet of the cover according to the amount of water collected in the dust collecting container; A filter assembly 800 installed to surround the outside of the opening and closing means to allow air to pass through and filter out water; And a water penetration barrier 401 for blocking the water sucked from the suction hose from being directly discharged toward the opening and closing means before being collected in the dust collecting container. .

Hereinafter, for convenience, components using the same name as in the first embodiment will be given the same numbers.                     

The opening and closing means supports the movement of the plotter 770 and the floater 770 to open and close the first discharge port 500 of the dust collecting container while rising according to the amount of water collected in the dust collecting container 300 as in the first embodiment. While the inlet hole 710 is formed through the plotter guide 700 so that the inflow of air and water along the circumferential surface is made.

In addition, an upper side of the main body 100 and an upper portion of the cyclone dust collector 300 and the fan / to allow air to flow to the fan / motor assembly 200 through the cyclone dust collector 300. The connection passage 450 is configured to connect the motor assembly 200 in communication.

The cyclone dust collector 300 has a substantially cylindrical body 310, an inlet 601 formed to communicate with the suction port 110 at an upper end of the body 310, and air sucked through the center portion thereof. A first discharge port 500 is formed and is configured as a cover 400 mounted to cover the upper end of the body 310.

Here, the inlet 601 is formed with a flow path toward the circumferential direction of the body to guide the air and water introduced through the suction port 110 in the circumferential direction of the body.

The cylindrical plotter guide 700 extending to the lower portion of the first discharge port 500 is fixed to the inner side of the cyclone dust collecting container 300, and is freely moved up and down inside the floater guide 700. A floater 770 is formed and floated by the water collected in the cyclone dust collector 300, and closes the first outlet 500.

A plurality of inlet holes 710 are formed at the side of the plotter guide 700 to allow air to pass therethrough.                     

In addition, the filter assembly 800 is detachably installed on the outside of the plotter guide 700 to surround the plotter guide 700.

The filter assembly 800 is composed of a cylindrical filter body portion 810 having a plurality of through holes 820 formed in the side portion, and a filtering net 830 installed to surround the outer surface portion of the filter body portion 810, By filtering the dust and water having a large particle from the air to be the air to remove the dust and water serves to discharge through the first outlet (500).

Of course, since the filter net 830 is formed through the micro-pores through which air can pass, most of the minute dust and moisture in the air that is instantaneously filtered out from the filter net, but is gradually collected from the lower portion of the cyclone dust collector 300 There is no problem in supporting the plotter 770 because the accumulated water can naturally pass through the filter net.

Meanwhile, in order to detachably fix the filter assembly 800 to the outside of the plotter guide 700, three 'L' shaped locking jaws 720 are formed at the outer circumference of the upper end of the plotter guide 700, and the filter Three fixing ribs 840 are inserted into and coupled to the outer circumference of the upper end of the filter body 810 of the assembly 800 through the open portion of the locking jaw 720.

Therefore, if one end of each of the fixing ribs 840 is aligned with the open portion of the locking jaw portion 720, and then the filter body portion 810 is rotated, the fixing ribs 840 are caught and supported while being inserted into the locking jaw portion 720. In the case where the filter assembly 800 is separated from the plotter guide 700, the filter body 810 is rotated in the opposite direction to the fixing rib 840, and the fixing rib 840 is easily separated from the locking jaw 720.

The water penetration barrier 401 is formed to surround the outside of the filter assembly 800.

The water penetration barrier 401 may be formed integrally with the cover 400 from the time of manufacture, or may be of a removable structure.

Although not shown, in the second embodiment, the water penetration barrier 401 as in the first embodiment shown in FIG. 3 has a structure integrated with the plotter guide 700 instead of the cover 400 or the plotter guide ( 700 may be of a removable structure coupled to the screw coupling, interference fit, of course.

 On the other hand, the combined water cleaning vacuum cleaner of the present invention may be configured to clean by spraying water and / or detergent to the carpet surface when performing cleaning by sucking water from the bottom surface, such as carpet, for this purpose 100) A storage container (not shown) storing water and / or detergent on one side of the inside and a pump 190 for pumping water and / or detergent of the storage container and discharging them to the outside may be additionally installed.

The operation of the second embodiment configured as described above is as follows.

When the user applies power, suction power is generated in the fan / motor assembly 200, and water and dirt are sucked together with air through an external nozzle assembly (not shown), and the sucked air, water, and dirt are suction hoses. Through the 600 and the suction port 110 is introduced into the inlet 601 of the cyclone dust collector (300).                     

At this time, the inlet 601 has a flow path in the circumferential direction with respect to the body 310 of the cyclone dust collector 300, the air, water and dirt discharged into the body 310 through the inlet 601 is the body It has a velocity component in the circumferential direction of the 310 to rotate and spiral down along the inner wall surface of the body 310, the relatively heavy water and dirt are descending while rotating spirally along the circumferential direction by centrifugal force It is guided to the lower body 310.

Among the dirt, such as water and dust, which are strongly sucked by the cyclone dust collecting method, the water collides and splashes with each other or the inner surface of the dust collecting container when the water rotates rapidly in the dust collecting container 300 directly, toward the filter assembly 800. It may flow.

In this case, although a very small through hole 820 and the like are formed in the filter assembly 800, water is splashed at a high speed and a strong impact amount, so that water immediately passes through the through hole 820 of the filter assembly 800. It may enter and exit through the first outlet 500, the water penetration barrier 401 surrounding the filter assembly 800 to prevent the fried water from flowing directly to the filter assembly 800. do.

In addition, since the lower portion of the water penetration barrier 401 has an open structure, the air having a relatively small weight and water having a fine particle size almost flows toward the filter assembly 800 by suction because there is almost no centrifugal force. The fine water is filtered by the filter net 830 of the filter assembly 800, only the air is passed through the filter net 830 and blown through the connection flow path 450 to the fan / motor assembly 200, the outlet 900 Is discharged to the outside through.

As described above, the present invention is not limited to the above embodiments, and one of ordinary skill in the present invention can implement another modified embodiment within the essential technical scope of the present invention.

For example, as shown in Figure 6 by adding a protective portion 402 made of a sound-absorbing material to the outer surface of the water penetration barrier 401 was strongly sucked to rotate in a cyclone method inside the dust collector (300) When an object made of a hard material is splashed with water to hit the water penetration barrier 401, noise and damage that may occur may be prevented.

In FIG. 6, the protection unit 402 is attached to the water penetration barrier 401 in the vacuum cleaner having the filter assembly 800, but the protection unit 402 does not have the filter assembly 800. Of course, it is also applicable to a vacuum cleaner.

As described above, according to the present invention, a wall is formed around the plotter guide in a predetermined shape to prevent the water coming into the plotter guide from penetrating into the plotter guide while being directly splashed by the water with strong suction force.

This prevents water penetrating into the plotter guide from escaping and affecting components such as a fan / motor assembly or an electric circuit, thereby improving reliability of the product.
