Field of the Invention The present invention relates to a vacuum cleaner capable of water suction cleaning, and more particularly, to a filter assembly of a vacuum cleaner combined with a water cleaner capable of preventing the water sucked into the main body of the vacuum cleaner from flowing into the motor through the suction passage. .

In general, a vacuum cleaner is a household appliance that generates a strong suction force in the main body to clean by collecting dust and dirt from the floor, such as flooring floor inside the main body of the vacuum cleaner, in recent years, in addition to the basic function of collecting dry dust, Detachable mop cleaning can be carried out, or a simple attachment, such as replacing the nozzle assembly, can be used to repeatedly clean and spray water and detergent from the vacuum cleaner itself and perform water cleaning. have.

Korean Patent Application No. 2003-0056923 (filed Aug. 18, 2003) discloses a water cleaning combined use vacuum cleaner developed by the applicant, which uses a cyclone dust collection method. By allowing the collection of dry foreign material, it is configured to perform water suction cleaning and dry foreign material suction cleaning without using a paper filter.

The combined water cleaning vacuum cleaner is provided with a cylindrical cyclone sump collecting and collecting water and air from the outside inside the main body, and the cyclone sump is in communication with a fan / motor assembly installed inside the main body through a suction flow path. The cyclone sump and the suction passage are connected to a filter assembly for filtering fine dust and water and a plotter for blocking the suction passage when full water is provided, and the suction force is caused by the fan / motor assembly. When this occurs, water and air are circumferentially sucked into the cyclone sump from the outside, and the sucked water and air are separated by centrifugal force so that the water is collected inside the cyclone sump and only the air passes through the suction channel. It is designed to flow towards the motor assembly.

By the way, the conventional vacuum cleaner combined with the above-described structure of the vacuum cleaner generates a strong rotational flow while the water sucked into the cyclone sump flows in the circumferential direction, so that the water is filled to the bottom of the bottom of the filter assembly. If the rotating water hits the filter assembly or suddenly springs into the filter assembly due to vortex generation, the overflow occurs. Therefore, the overflowed water in the state that does not support the floater There is a problem that flows into the fan / motor assembly through the suction passage and adversely affects.

Accordingly, the present invention has been made in order to solve the above problems, and prevents the water flowing into the cyclone sump can overflow into the filter assembly before the plotter operates, the fan / motor through the suction flow path It is an object of the present invention to provide a filter assembly of a vacuum cleaner combined with a water cleaner to prevent water from flowing into the assembly.

The present invention for achieving the above object, the fan / motor assembly is installed inside the main body to generate a suction force, the outlet port is formed in communication with the fan / motor assembly in the main body and the air discharged, A suction hose connected to the main body from the outside to guide the air and water sucked from the outside into the main body, and guides the air and water sucked through the suction hose in the circumferential direction to separate the water, foreign matter and air by centrifugal force A substantially cylindrical cyclone sump, a suction flow path connecting the upper portion of the cyclone sump and a fan / motor assembly, and a substantially cylindrical floater installed in a connection portion of the cyclone sump inside the suction flow path. The guide and the inside of the plotter guide can be freely moved up and down to fill the amount of water filled in the cyclone sump. And a floater which moves up and down and blocks and opens the suction flow passage, and comprises a substantially cylindrical filter assembly installed to surround the outside of the plotter guide and having a filtering network for filtering water on the side. The at least one rib protrudes downward from the bottom surface of the filter assembly, and provides a filter assembly for a vacuum cleaner as well as water.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the filter assembly of the combined water cleaning vacuum cleaner according to the present invention will be described in detail.

First, Figure 1 is a cross-sectional view of the main portion schematically showing the configuration of the vacuum cleaner combined with the filter assembly according to the present invention, as shown in Figure 1, the suction force to the lower rear portion inside the vacuum cleaner main body 10 The fan / motor assembly 20 is installed, and a suction port 11 connected to an external suction hose 60 is formed in front of the main body 10, and the suction part is provided at the front of the main body 10. The cyclone sump 30 which is connected to the port 11 and collects water and dirt introduced through the suction port 11 is separably installed, and the fan / motor assembly is located behind the main body 10. The outlet 12 is formed in communication with the 20 so that the air is discharged to the outside.

In addition, the upper side of the main body 10, the upper portion of the cyclone sump (30) and the fan / motor assembly (so that the air flows to the fan / motor assembly 20 through the cyclone sump (30) ( A suction passage 40 is configured to connect 20 to each other.

The cyclone sump 30 has a substantially cylindrical body 31, an inlet 32 formed to communicate with the suction port 11 at an upper end of the body 31, and air sucked through the central portion. Opening hole 34 is formed and is mounted to cover the upper end of the body 31, and is installed rotatably in the vertical direction in the middle portion of the inside of the body 31, the body to the upper and lower It consists of the partition bodies 35 of the shape of two semicircle plates which are made to partition.

Here, the inlet 32 has a flow path formed in the circumferential direction of the body to guide the air and water introduced through the suction port 11 in the circumferential direction of the body.

In addition, a through hole 36 is formed at an outer circumferential portion of the partition wall 35 so that water and dirt introduced from the upper part may be sent to the lower wall of the partition wall 35. The partition 35 functions to isolate foreign substances such as dust when inhaling general dry foreign substances rather than cleaning them with water.

A cylindrical plotter guide 70 extending downward of the opening hole 34 is fixed to the lower side of the cover 33 of the cyclone sump container 30, and the upper and lower sides of the plotter guide 70 are fixed. The floater 75 is provided to close the opening 34 while being freely moved and being floated when the water collected in the cyclone sump 30 reaches a predetermined level. A plurality of through holes 71 are formed at the side of the plotter guide 70 to allow air to pass therethrough.

In addition, the filter assembly 80 is detachably installed on the outside of the plotter guide 70 so as to surround the plotter guide 70. The filter assembly 80 has a cylindrical shape in which a plurality of through holes 82 are formed at a side surface thereof. The filter body portion 81 and the filter net 83 is provided so as to surround the outer surface portion of the filter body portion 81, the air from which the water is removed by filtering the water from the intake air is open hole (34) It serves to discharge through.

On the other hand, as shown in detail in Figure 2, the lower surface of the filter assembly 80, ribs 85 for preventing the rotation of water immediately below the filter assembly 80 so as to protrude in a cross (+) shape. Wherein the end of the cross-shaped rib 85 is almost in contact with the partition wall (35).

Combined water cleaning vacuum cleaner configured as described above operates as follows.

When the user applies power while cleaning the water suction, suction power is generated in the fan / motor assembly 20, and water and dirt are sucked together with the air through an external nozzle assembly (not shown), and the sucked air and water and The dirt flows into the inlet 32 of the cyclone sump 30 through the suction hose 60 and the suction port 11.

At this time, since the inlet 32 has a flow path in the circumferential direction with respect to the body 31 of the cyclone sump 30, the air, water and dirt discharged into the body 31 through the inlet 32 are the body It has a velocity component in the circumferential direction of (31) to rotate spirally along the inner wall surface of the body 31, the relatively heavy water and dirt is descending while rotating spirally along the circumferential direction by centrifugal force As a result, dust is collected on the partition 35 installed below the body 31 and then guided to the lower portion of the body 31 through the through hole 36.

In addition, since the relatively small weight of the air and the water of the fine particles have almost no centrifugal force, the air flows toward the filter assembly 80 by the suction force. At this time, the water is filtered by the filter network 83 of the filter assembly 80. Only air passes through the filter net 83 and is blown through the suction flow path 40 to the fan / motor assembly 20 is discharged to the outside through the outlet (12).

When water is accumulated in the body 31 of the cyclone sump 30 through a process as described above, the floater 75 located inside the plotter guide 70 is supported by the internal pressure to float the cyclone home. The upper opening 34 of the water bottle 30 is closed, thereby blocking the suction flow path.

When the water in the cyclone sump (30) is filled to a predetermined level, the user may open the cover of the body 10, separate the cyclone sump (30) and discard the water.

On the other hand, as described above, the water sucked into the cyclone sump (30) causes a strong rotational water flow by the centrifugal force, the height of the water accumulated in the cyclone sump (30) ribs 85 of the filter assembly 80 When the height is reached, the rotation of the water is prevented by the ribs 85 directly below the filter assembly 80, thereby preventing the vortex phenomenon. The phenomenon of overflowing is prevented, so that water does not flow into the suction flow path 40 in the state in which the plotter 75 is not supported.

And, if you want to clean the general dry dust by using the combined water cleaning vacuum cleaner, when the power is applied in a state in which the cyclone sump (30) is empty suction power is generated by the operation of the fan / motor assembly 20 Air and dust are sucked through the inlet 32 of the cyclone sump (30).

Air and dust sucked into the cyclone sump (30) has a velocity component in the circumferential direction of the body 31, as described above, the relatively heavy dust is inside the body 31 by centrifugal force Spirally rotated downward along the wall and collected, relatively small air and fine dust are directed toward the filter assembly 80 by suction force because there is little centrifugal force, where air is filtered through the filter network (83) of the filter assembly (80). ) Is blown through the suction passage 40 toward the fan / motor assembly 20, and the fine dust is caught by the filter net 83 of the filter assembly 80 and filtered.

As described above, according to the present invention, since the water sucked inside the cyclone sump is blocked by the ribs of the filter assembly, the water sucked in the state where the plotter is not operated suddenly overflows into the filter assembly and is sucked in. Inflow into the flow path is prevented, and thus the fan / motor assembly generating the suction force can be safely protected from water.
