Detailed Description

Hereinafter, preferred embodiments of the present invention will be described based on the drawings. However, the scope of the claims of the present invention should be defined as described in the claims of the present invention. Also, a description of a related art that may obscure the gist of the present invention will be omitted.

As shown in fig. 4, the basic structure of the air cleaning apparatus of the present invention includes an outer tank 100, an inner tank 200, a moisture remover 300, a combining cover 101, an inhalation apparatus 400, a dust collector 500, a control switch 600, a power supply apparatus 700, and a housing 800, and may further include a deodorizer 1000.

The suction device 400 reduces the internal pressure by sequentially sucking the internal air of the moisture remover 300, the inner tank 200, and the outer tank 100 so as to suck the internal air through the suction pipe 130. Therefore, when air is sucked into the inhalation device 400, the space from the suction pipe 130 to the outer canister 100, the inner canister 200, the moisture remover 300, and the inhalation device 400 should be unobstructed.

The dust collector 500 functions to remove foreign substances in the air passing through the moisture remover 300. In detail, foreign substances such as dust in the air passing through the dust collector 500 are removed by an electric dust collector such as an RC dust collector.

The power supply device 700 supplies power to the inhalation device 400, and the power supply of the power supply device 700 is controlled by controlling the switch 600.

The deodorizer 1000 functions to remove the smell of the air passing through the dust collector 500, and an activated carbon filter may be used, for example.

All of the above-described structures are housed in the housing 800.

Fig. 1 is a diagram showing the configuration of the main part of the present invention, and referring to the diagram, the outer tank 100, the inner tank 200, and the moisture remover 300, which are the main characteristic parts thereof, will be described in more detail as follows.

The outer tank 100, which is a tank that sucks contaminated external air through the suction pipe 130 and accommodates water therein, preferably has a cylindrical shape in consideration of a coupling relationship with a coupling cap 101 described later.

As shown in fig. 5, if the outer cover 120 having a bamboo hat shape is provided at the introduction part of the suction pipe 130, contaminated outside air can be collected by the suction pipe 130 without diffusion.

The inner tank 200 is received inside the outer tank 100 such that water of the outer tank 100 and contaminated external air sequentially flow in to generate a mixing action of contaminated materials of the contaminated external air adsorbed to the water, and as such a tank, also takes a cylindrical shape, a diameter and a height which are smaller than those of the outer tank 100, including a plurality of perforated plates 230. The reason why the inner tank 200 is formed in a cylindrical shape is to immediately condense and drop the moisture removed through the dewatering ports 331 of the dewatering pipes 330, which will be described later, and it is not necessary to form the entire shape in a cylindrical shape, and at least a portion for accommodating the dewatering pipes 330 may be formed in a cylindrical shape corresponding thereto.

The porous plate 230 is a thin plate having a plurality of holes formed therein and a diameter corresponding to the inner diameter of the inner tank 200, and the plurality of porous plates 230 penetrating the inner tank 200 are stacked at predetermined intervals. The water is introduced into the inner tank 200 through the holes formed in the perforated plate 230, and then a lot of bubbles, that is, a foaming phenomenon, are generated when air is introduced into and passes through the water. Therefore, the pollutants contained in the contaminated air PA are effectively adsorbed to the water W by enlarging the contact surface area between the contaminated air PA and the water.

The lower end of the inner tank 200 may have a structure in which an opening and closing valve 210 and an inflow pipe 220 are formed as proposed in korean laid-open patent No. 10-2011-0120655, and may be divided from the inside of the outer tank 100 by forming a porous plate 230 up to the lower end of the inner tank 200.

Therefore, in the case where the suction apparatus 400 is not activated, if the suction apparatus 400 is activated after the water W maintains the same water level in the inner tank 200 and the outer tank 100 as shown in part (a) of fig. 2, water flows into the inner tank 200 first and then air flows into the water as shown in part (b) of fig. 2. When the power supply to the suction device 400 is turned off after the air cleaning operation is finished, the state is returned to the state shown in fig. 2 (a).

The moisture remover 300 functions to remove moisture from the air passing through the water in the inner tank 200, and as shown in the drawing, includes a moisture filter 310, an inner cover 320, and a dehydrating pipe 330 in the upper portion of the inner tank 200.

The moisture filter 310 is densely woven so that air in the air containing moisture passes through and moisture with large particles is filtered. As shown in fig. 2, such a moisture filter 310 may be divided into two embodiments according to the installation position, and a reference numeral "310 a" is given to the moisture filter 310 provided at the lower end of the inner cover 320, and a reference numeral "310 b" is given to the moisture filter 310 provided inside the coupling cover 101, that is, at the coupling portion between the coupling cover 101 and the dewatering pipe 330.

First, the moisture filter 310a provided at the lower end of the inner cover 320 is explained, and the air passing through the inner tank 200 contains a lot of moisture, and the water itself flowing into the inner tank 200 is quickly sucked up by the suction force of the suction device 400, and the moisture of such macro-particles is first blocked by the moisture filter 310 a. Sponge or non-woven fabric can be used, and waterproof fabric with good air permeability but poor hydrophilicity can also be used. As shown in fig. 2, the most preferable form is to surround the entire upper portion of the inner tank 200, and the moisture filtered by the moisture filter 310a directly falls to the inner tank 200.

The moisture filter 310b provided at the coupling portion between the coupling cover 101 and the dehydrating pipe 330 is made of the same material as the moisture filter 310a described above, and serves to completely filter out moisture that has not been filtered out in the dehydrating pipe 330 and prevent the moisture from flowing into the suction device 400.

The inner cover 320 functions to collect air passing through the inner can 200 or the moisture filter 310a, and is shaped like the outer cover 120 to form a bamboo hat shape at the upper portion of the inner can 200.

In summary, the outer peripheral surface of the moisture filter 310a is coupled to the lower end inner surface of the inner cover 320 corresponding to the inner peripheral surface of the inner cover 320. Except that the diameter of the inner cup 320 is smaller than the inner diameter of the inner can 200, thereby creating a space between the inner cup 320 and the inner face of the inner can 200. This is to provide a space for allowing the water flowing out of the dewatering port 331 to flow down.

The dehydration pipe 330 is a pipe connected to the inner cover 320 and bent several times in a spiral form, and allows moisture having small particles contained therein to be adsorbed on an inner wall of the pipe in a process of passing the air collected in the inner cover 320. This is to filter out moisture having small particles that cannot be filtered out by the moisture filter 310a (although the moisture filter 310a is not a requirement), and if a plurality of dewatering ports 331 are formed in the side wall of the dewatering tube where the moisture moving along the dewatering tube 330 collides with the side wall by the centrifugal force, the moisture adsorbed on the side wall of the dewatering tube 330 can be discharged and flow into the inner tank 200 again.

As described in more detail with reference to fig. 3, when moisture is contained in the air a moving along the dehydrating pipe 330, the moisture is separated in the opposite direction to the rotation center by the centrifugal force during the rotation movement, and collides with the inner wall of the dehydrating pipe 330 in the process. The water attached to the inner wall of the dewatering pipe 330 is condensed and discharged to the dewatering port 331. Only, even if the dewatering port 331 is not formed, the condensed moisture is not discharged to the connection pipe 101c by its weight and stays in the dewatering pipe 330, and then naturally drops to the inner tank 200 through the inner cover 320 and the moisture filter 310a by gravity when the operation of the suction device 400 is interrupted. However, since there is a possibility that the water cannot pass downward through the water filter 310a, in the case where the dehydration opening 331 is not formed in the dehydration tube 330, it is preferable to form a hole through which the water can fall toward the water filter 310a alone or use a special waterproof material through which the water can pass from the top to the bottom and cannot pass from the bottom to the top.

In the case of forming the dewatering opening 331, it is preferable that the dewatering opening 331 is formed in a side wall contacting an outer diameter of a circle formed by spirally rotating the dewatering pipe 330, and as shown in fig. 3, a hole 331a is formed when viewed from a direction in which air is rotated, and a partition 331b is formed when viewed from the opposite direction. That is, if the tangential line (moving direction of air) at the position where the dewatering port 331 is formed is 0 degree and the opposite direction from the dewatering port 331 to the center of the dewatering pipe 330 is 90 degrees, it is preferable to form the hole so that the angle of the direction of the through hole 331a is 0 degree to 60 degrees. Accordingly, the water droplets condensed in the holes 331a can be easily discharged to the outside of the dehydrating pipe 330 by the force of the rotation of the air.

On the other hand, when the dewatering pipe 330 is bent several times in a spiral form so as to maintain a predetermined interval from the inner wall of the inner tank 200, the water W discharged through the dewatering port 331 collides with the inner wall of the inner tank 200 and directly flows down as shown in the right part of fig. 3, and thus the water W discharged from the dewatering pipe 330 can be easily collected in the inner tank 200. In particular, if the dewatering ports 331 are positioned on a straight line in the longitudinal direction on the pipes in which the dewatering pipes 330 spirally rotate and are stacked, the water W discharged through the dewatering ports 331 falls down along the inner tank 200 and is aggregated with each other, and can be easily collected in the inner tank 200 without scattering particles.

The dehydration pipe 330 and the suction device 400 are connected by a connection pipe 101c, and the purified air CA circulated in the dehydration pipe 330 and having moisture removed flows into the dust collector 500 through the suction device 400 by the connection pipe 101 c.

The coupling cover 101 serves to couple the outer tank 100, the inner tank 200, and the moisture remover 300, and may include an outer tank coupling portion 101a, an inner tank coupling portion 101b, and a connection pipe 101 c.

The outer can coupling part 101a is formed in a groove shape corresponding to the upper end of the outer can 100 at the lower surface of the coupling cover 101 such that the upper end of the outer can 100 is snap-coupled to the outer can coupling part 101 a. In the case where the upper end of the outer can 100 is formed in a circular shape and has a screw thread, and the outer can coupling portion 101a is also formed with a circular groove having a corresponding screw thread, the outer can 100 and the coupling cover 101 can be rotated to open and close, thereby improving sealing force.

The inner tank coupling part 101b is formed in a groove shape corresponding to the upper end of the inner tank 200 at the lower surface of the coupling cover 101 such that the upper end of the inner tank 200 is snap-coupled to the inner tank coupling part 101 b. It goes without saying that the outer tank coupling part 101a is formed inside the outer tank coupling part 101a in a smaller size.

The connection pipe 101c is formed on a side surface of the coupling cover 101, and forms a space inside the coupling cover 101 so as to be connected to the dehydration pipe 330 coupled to a lower surface of the coupling cover 101. Accordingly, the air is moved from the dehydrating duct 330 to the suction device 400 through the coupling cover 101 and the connection duct 101 c.

Fig. 6 is a view showing a process of separation for cleaning the air cleaning apparatus of the present invention. First, in the drawings, the portions denoted by C1 to C5 are detachable portions. First, in the state shown in fig. 6 (a), when the joint C1 between the outer tank 100 and the suction pipe 130 is separated and the joint C2 between the joint cover 101 and the connection pipe 101C is separated, the state shown in fig. 6 (b) is formed. When the coupling portion C3 of the coupling cover 101 and the outer can 100 is separated, the state shown in part (C) of fig. 6 is formed. Thereafter, when the coupling cover 101 is separated from the coupling portion C4 of the inner tank 200 and the coupling portion C5 of the coupling cover 101 and the dehydrating pipe 330 is separated, all the components are disassembled as shown in fig. 6 (d). In this case, as shown in the drawing, each porous plate 230 may be connected by a support frame 230a so as to be an integral member.

The form of the joint portion may be a screw joint, and may be implemented in various forms.

Thereby, water is easily injected and discharged into and from the outer tank 100 and the inner tank 200, so that the cleaning of the respective components of the air cleaning apparatus becomes easy.

Also, the air cleaning apparatus thus constructed can minimize the volume, and thus, as shown in fig. 5, can be manufactured in a seat form for easy removal and use.

It will be apparent to those skilled in the art that the present invention described above is not limited to the above-described embodiments and drawings, and that various substitutions, modifications and changes may be made to the present invention without departing from the scope of the technical idea of the present invention.
