In general, the impeller is mounted on a rotating motor to suck in and discharge air, and to mix the surrounding fluid by rotation. have.

For example, a radial impeller used in a wet air purifier pushes a fluid radially outward by a centrifugal force generated by rotation.

However, the impeller according to the prior art has a limitation in refining the particles of the fluid when the fluid is scattered outward in the radial direction. That is, since there is a limit to atomizing the size of the liquid scattered through the impeller, the probability that the liquid scattered through the impeller falls to the periphery of the air purifier increases. Therefore, only pollutants (eg, chemicals, fine dust, bacteria, pollen, etc.) existing in a small space around the air purifier are purified, and pollutants in the air present in a large space cannot be removed.

Accordingly, there is an increasing demand for an impeller having a new structure capable of removing contaminants in the air existing in a large space by atomizing the liquid scattered through the impeller.

Accordingly, an impeller (Korean Patent Application Laid-Open No. 10-2019-0139730) that can atomize and scatter liquid has been proposed, and the impeller is by installing a porous mesh network on the wing portion, thereby atomizing the liquid scattered through the impeller. However, since the porous mesh network is provided to surround a plurality of wings on the outer side of the wing in the circumferential direction, the time and space for contacting water and fine dust or harmful gas is insufficient, and the water surface area is narrow, so the adsorption efficiency is lowered. In addition, there is a problem of cumbersome use because the discharge path of the removed foreign substances is blocked, and the cleaning cycle for the foreign substances is short.

In order to solve this problem, the present applicant has applied for a fan blade No. 10-2020-0035122, the fan blade is disposed in the air flow path of the water treatment type air purifier, is installed on the rotating shaft of the motor and rotates, and the upper and lower plates are It is formed in a circular shape, and an open first flow path is formed in the center of the lower plate, and extends between the upper plate and the lower plate along the circumference of the first flow path. Water and air continuously collide in the first and second passages on a plurality of perforated mesh plates attached to either side of the upper or lower plate of the formed blade body, reducing the size of water and increasing the contact time and space with air, By passing it through, foreign matter contained in the air was removed, but workability during assembly was poor and water and air quickly escaped the porous mash plate due to the strong centrifugal force generated by fast rotation, so the porous mash plate was broken and crushed. There was a problem with losing.

The porous mesh plate 150 is reflected in the central direction (all directions) while strongly colliding with air containing water and fine dust or harmful gas or passes through the second flow path 141 formed by the upper and lower limbs 140 . to the outside or move along the third flow path 142 formed between the plurality of upper and lower limbs 140 to widen the surface area, and to allow water and fine dust or harmful gas to contact as much as possible. At this time, the second flow path 141 is a movement path that passes through the perforated mesh plate 150, and passes through when water or air to which foreign substances are not attached is crushed by diffuse reflection to the outside immediately without passing through the second flow path. is the way out

At this time, the fan blade 100 for air purification is fixedly installed between the central axis column 130 and the upper and lower legs 140 between the upper plate 110 and the lower plate 120 , and the water sprayed from the central axis column 130 . A guide unit 160 for guiding the air and the upper and lower limbs 140 to which the porous mesh plate 150 is coupled is installed so that the guide unit 160 is connected to the upper and lower limbs 140 , that is, the porous mesh plate 150 . It is provided to guide the moving water.

On the other hand, the guide part 160 is provided with a curved wing part 161 with an open upper part and a closed lower part for guide, so that water and air are transferred to the perforated mesh plate 150 through the second flow path 141 and the third A lower plate coupling groove 162 that is guided to the flow path 142 and fixedly coupled to the guide part coupling protrusion 123 formed on the lower plate 120 is formed and is fixedly installed on the lower plate 120 .

The guide part 160 is formed with a guide part upper plate 160a and a guide load plate 160b, the guide part upper plate 160a is fitted to the upper plate 110, and the guide part plate 160b is a lower plate ( The lower plate coupling groove 162 is fitted and coupled to the guide part coupling protrusion 123 of 120).

In addition, the guide part 160 is seated between the lower fixtures 121 on the outside of the guide part coupling protrusion 127 formed on the lower plate 120 .

Here, the second flow path 141 is formed between the upper and lower limbs 140 to which the porous mesh plate 150 is coupled to a plurality of detailed flow paths, so that water and air move, and the third flow path 142 moves to It can also be a passage.

When water and foreign substances move through the porous mesh plate 150 along the second flow path 141 and the third flow path 142 , the water passes through the porous mesh plate 150 and the foreign substances are transferred to the porous mesh plate 150 . It is caught and moved to the outside by the centrifugal force of the fan blade 100 for air purification to move to the end of the fourth perforated mesh plate 150 .

In this process, water and air continuously collide, separate, and come into contact, so that foreign substances in water and air are combined.

The movement of water and foreign substances moves to the wind wing plate 144 of the upper and lower limbs 140 formed at the edges of the upper plate 110 and the lower plate 120, so that the air easily escapes to the outside, and the foreign substances fall and fall into a water tank (not shown). ) falls on

Since the movement of water and foreign substances does not stop between the porous mesh plates 150 and moves to the water tank, the adhesion of foreign substances to the porous mesh plate 150 is minimized, so that their cleaning intervals are increased. In addition, the perforated mesh plate 150 located at the edge continues to strongly collide with the air, allowing some to pass, and some to move to a curved surface.

On the other hand, the present invention is a fan blade 100 for air purification that is mounted on a motor at the top of the water treatment air purifier and rotates. There is a water tank (not shown) at the bottom, and indoor air can enter the side, and the water tank by a separate driving force. The water inside rises from the water tank to the top of the fan blade 100 for air purification.

In addition, the fan blade 100 for air purification that circulates the indoor air allows water and air to meet in the passage through which the indoor air circulates so that foreign substances in the air are adsorbed.

As described above, the fan blade 100 for air purification of the present invention is rotated by a motor, and as water rises, the air is discharged outside in a purified state.

Air containing foreign substances directly and repeatedly passes through the porous mesh plate 150 together with water, and some water and large particles flow along the porous mesh plate 150 surface.

In this process, air containing foreign substances is adsorbed to water through repeated contact.

And, in the porous mesh plate 150, dust particles of a certain size or more do not accumulate and do not pass through the porous mesh plate 150 and flow along the outside side through the edge gap open at the end between the upper and lower limbs 140 to the lower part. falls and enters the tank.

Therefore, the fan blade 100 for air purification of the present invention is disposed in the air passage of the water treatment type air purifier, and a central shaft column through which water flows is formed in the center of the upper and lower plates, so that the water and air introduced from the plurality of passages are separated from each other. By continuously colliding and reducing the size of water while passing through the fan blade while increasing the contact time and space with the air, there is an effect that the foreign matter contained in the air is easily removed.

In addition, in the present invention, the upper and lower limbs 140 are provided in a form in which a plurality of H-shape are connected to each other, the porous mesh plate 150 is coupled from the inside, and is fixedly installed to the upper plate 110 and the lower plate 120, The upper plate 110 and the lower plate 120 are firmly fixedly coupled by the upper fixture 111 and the lower fixture 121 protrudingly formed to stably support the porous mesh plate 150 .

And, the present invention blocks both sides of the upper and lower supports 140 on the upper plate 110 and the lower plate 120 like weirs and supports the perforated mesh plate 150. The upper fixture 111 and the lower fixture 121 protrude. is formed, and the pillars of the upper and lower supports 140 are inserted between the upper fixture 111 and the lower fixture 121, and the upper step 112 and the lower step on the outside of the upper fixture 111 and the lower fixture 121 (122) is further formed, there is also an effect of firmly fixing it so as not to fall backward.

On the other hand, in the present invention, the wind blade plate 144 inclined so as to protrude to the outside of the upper plate 110 and the lower plate 120 from the upper and lower limbs 140 is further formed, so that the fan blade rotates counterclockwise and air is blown out. When exiting, it increases the sound pressure inside, helping the air inside to escape smoothly to the outside.

In addition, in the present invention, the inner corners of the upper fixture 111 and the lower fixture 121 are formed to be rounded, so that the porous mesh plate 150 is not slippery when inserted into the upper fixture 111 and the lower fixture 121. It is inserted to facilitate assembly.

And, in the present invention, the guide part 160 is mounted between the upper and lower supports 140 to which the central shaft column 130 and the perforated mesh plate 150 are coupled between the upper plate 110 and the lower plate 120, so that the central axis Water and air sprayed from the column 130 are guided between the upper and lower limbs 140 to which the porous mesh plate 150 is coupled.

On the other hand, in the present invention, the upper and lower supports are bent at both ends of the porous mesh plate 150 at the beginning and the end of the pillars 143 for assembly coupled to the upper and

lower plates

110 and 120 in the upper and lower supports 140. Since the fixing part insertion groove 143b into which the top 151 is inserted is formed and coupled to the porous mesh plate 150, the porous mesh plate 150 is firmly fixedly coupled.

And, in the present invention, a plurality of upper and lower limbs 140 and porous mesh plate 150 are alternately arranged at intervals of 90 degrees on the upper plate 110 and the lower plate 120 to increase the surface area and air containing fine dust or harmful gas. As the water and the water pass through the porous mesh plate 150 of several stages, the contact is repeated, and there is an advantage in that fine dust or harmful gases are maximally adsorbed to the water.
