Description

The water filter for air filtering with improved purification efficiency

The present invention relates to a water filter for air purification, which can significantly improve purification efficiency by reducing a bottleneck phenomenon when external polluted air sucked by a vacuum suction force is put into water, thereby injecting a larger amount of polluted air into water. It relates to a water filter for air purification that can be used.

The causes of indoor air pollution in buildings can be divided into outdoor pollution sources and indoor pollution sources. Outdoor pollutants include various types of fine dust, dust, and air pollutants included in the outdoor air introduced from the outside. etc. In order to prevent an increase in the degree of pollution of indoor air due to the above pollution sources, it is necessary to maintain and manage the indoor air pleasantly by supplying fresh air to the room through appropriate ventilation.

In addition, various pollutants (noxious gas and oil smoke) are emitted from the range hood of the kitchen and industrial sites, and various air purification devices have been developed and used in the effort to purify them.

In addition, a lot of harmful gases and oil smoke are mixed with the meat smoke produced when grilling meat in commercial facilities such as restaurants. However, since this is also just emitted into the atmosphere, concerns about exhaust gas and fine dust emitted from commercial facilities at the national level are also a topic of discussion.

In general, the air purifying device includes an air purification method through a physical filter using a nonwoven fabric, a method of purifying air through a liquid such as water, an adsorption method using electricity, and the like.

Among them, the air purifier using a physical filtration method using a filter made of non-woven fabric or fiber is designed to filter out dust and foreign substances while the indoor air passes through a dense filter. The filter loses its ability to purify due to a decrease in suction power by blocking all the micropores of this filter. For this reason, the filter must be changed frequently. In particular, as the filter is used in heavily polluted areas and the performance of the filter is excellent, the life of the filter is quickly exhausted.

As another prior art, there is a method of purifying the air by spraying water on the inhaled polluted air. This method has a problem in that the purification ability rapidly decreases when the amount of inhaled air increases, and the polluted air and water are mixed evenly There is a problem in that the filtration efficiency for dust and the like is significantly lowered.

In order to solve the various problems as described above, a "water filter for air purification" by the present applicant is disclosed in Korean Patent No. 10-2047383.

As shown in Fig. 1a), the water filter is a hollow body filled with water up to a predetermined water level, and a body 110 configured to be sealed inside is provided, and a hollow tube 120 is vertical in the inner center of the body. and a vacuum unit providing a vacuum suction force inside the main body is formed to communicate with an upper side of the main body.

Here, the upper end of the hollow tube 120 is composed of an outdoor air intake unit 1210 through which external polluted air is sucked, and the lower end is composed of an outdoor air discharge unit 1220 through which the polluted air is discharged into the water. In addition, the outdoor air discharge unit 1220 is formed with an eccentric discharge port 1221 so that the contaminated air is discharged into the water while turning in a spiral direction by centrifugal force.

In the water filter as described above, as the inside of the body becomes a vacuum by the vacuum suction force, the water filled in the hollow tube and the polluted air sucked through the outside air suction part escape into the body and come into direct contact with the water turning in the spiral direction. During mixing and stirring, foreign substances and odors in the air were removed, and only purified air was discharged out of the water.

However, if the water filter purifies a large amount of air, resistance is inevitably generated in the process of passing through the water surface when the inhaled polluted air is introduced into the water through the open lower end of the hollow tube submerged in water. There was a problem in that a bottleneck was generated on the water surface by this, and the efficiency of inputting polluted air was lowered. To explain the degree of the bottleneck, it is caused by the difference in mass between water and air, and the difference is much larger than expected. The density of water is 1,000 kg/m ³ , and the density of air is 1.2 kg/m ³ , so water has a mass value about 833 times greater than that of air. If the hollow tube is immersed in water by 1 cm, the polluted air has to pass through the mass of air corresponding to the length of the tube 8m and 33cm. Therefore, the depth of the distribution pipe submerged in water is preferably 10 mm or less. In the prior art, in order to reduce the input resistance, a number of main bodies 110 are configured in parallel as shown in FIG. 1b) to secure a path through which as much air passes as possible, thereby creating a bottleneck. However, when a plurality of main bodies are configured in parallel as described above, there is a problem in that the overall volume of the purification unit becomes too large and complicated.

The present invention was invented to solve the above problems, and when the external polluted air sucked by the vacuum suction force is put into the water, the bottleneck is reduced and the purification efficiency is achieved by putting a larger amount of polluted air into the water. It aims to provide a water filter for air purification that can significantly improve air quality and minimize components and volume.

For the above purpose, the present invention provides an air purification water filter for purifying external polluted air, which is a hollow body filled with water to a predetermined water level inside, and is configured to be sealed inside, but external air intake through which polluted air is introduced. a main body connected in communication with a vacuum device for providing a vacuum suction power and a vacuum device, and having a vacuum discharge unit formed on one side and the other side of the upper portion to discharge purified air; a hollow tube whose upper end is connected to be in communication with the outside air inlet, and through which external polluted air is vacuum sucked into the inside by a vacuum suction force; A plurality of branches are formed along the vertical and radial directions from the lower end of the hollow tube, the lower part is submerged in water to a predetermined height, and the lower end of the hollow tube consists of an outdoor air inlet through which polluted air is put into the water.

In addition, the present invention provides a cyclone fan in which a discharge port inclined from a radial direction is formed at the lower end of each branch pipe submerged in the water so that the vacuum-sucked polluted air is introduced into the water through the outdoor air inlet while turning in the circumferential direction. characterized by being

In addition, the present invention prevents the rotational force from being canceled by colliding with the air discharged through the adjacent cyclone fan while the contaminated air inside the hollow tube is rotated and discharged in the spiral direction through the cyclone fan. It is characterized in that a cyclone guide crossing between the cyclone fan and the cyclone fan is formed so that the airflow from the clone fan can rotate continuously without losing rotational force.

In addition, in the present invention, in the cyclone guide, when the contaminated air is rotated and discharged through each cyclone fan and the contaminated air and water are mixed and rotated, the rotational force of the discharge air stream discharged from each cyclone fan is the sum. It is characterized in that it is formed in a spiral shape in a direction corresponding to the rotational direction of the discharge air stream so that the outermost inside of the body can rotate strongly.

In addition, in the present invention, the cyclone fan formed in the branch pipe disposed in the center among the plurality of branch pipes is composed of a sun cyclone fan, and is formed in the branch pipe surrounding the branch pipe disposed in the center. The cyclone fan is composed of a planetary cyclone fan in which the discharge port is formed in the opposite direction to the sun cyclone fan and the air discharged in the opposite direction rotates in the opposite direction. It is characterized in that it is arranged in a form wrapped around it and is configured to accelerate rotation with each other when the external air is discharged and rotated.

In addition, in the present invention, a cyclone guide traversing between each planetary cyclone fan is formed between the planetary cyclone fan and the planetary cyclone fan so that the rotational force is not offset. When the contaminated air is rotated and discharged through the air, the respective rotational forces are summed so that the outermost inside of the body can rotate strongly.

In addition, in the present invention, the hollow tube is characterized in that it is arranged eccentrically from the main body so that the area of the vacuum part is formed to be wider when the vacuum is formed from the vacuum discharge part.

In addition, the present invention is a water splash prevention plate for preventing the water inside the main body from flowing into the vacuum discharge unit due to the vacuum suction force of the vacuum device is coupled along the horizontal direction in a form that surrounds a part of the hollow tube, the water The anti-friction plate is characterized in that one side is high and the other side is low, so that moisture separated from the air by weight flows along the slope and is recovered to the bottom surface of the body.

In addition, the present invention is a water filter for purifying air for purifying external polluted air, which is a hollow body filled with water to a predetermined water level inside, and is configured to be sealed inside, and an external air inlet and vacuum suction power through which polluted air from the outside is introduced. a main body connected in communication with a vacuum device providing a hollow tube whose upper end is connected to be in communication with the outside air inlet, and through which external polluted air is vacuum sucked into the inside by a vacuum suction force; a diffusion unit connected in communication with the lower end of the hollow tube and formed of a hollow structure with an empty interior to move contaminated air from the upper part to the lower part; As a middle bow structure, the upper end is connected in communication with the diffusion unit, and the outdoor air inlet at the lower end is submerged in water to put the contaminated air inside the diffusion unit into the water, and the diffusion unit so that a large amount of contaminated air can be simultaneously introduced into the water. A plurality of distribution pipes arranged to the maximum from the; A vacuum unit that is formed between the vacuum outlet and the outdoor air inlet and that the vacuum suction force by the vacuum device acts, so that the polluted air that has passed through the outdoor air inlet is put into water to be purified and then put into the vacuum outlet. characterized in that

When the purification efficiency according to the present invention made as described above is achieved by the water filter, the following effects are provided.

First, the present invention relates to the total length of the perimeter of the outdoor air inlet, which becomes a path for contaminated air to move from the inside of the hollow tube to the outside while the lower portions of the plurality of branch pipes branched from the lower end of the hollow tube are submerged in water to a predetermined depth. The bottleneck can be remarkably reduced when the polluted air is put into the water by maximizing it, and thus, a larger amount of polluted air can be put into the water than per unit time, which has the advantage of maximizing the purification efficiency.

Next, according to the present invention, a cyclone fan having a discharge port inclined from the radial direction is formed at the bottom of each branch, and when the vacuum-sucked polluted air is introduced into the water through the outdoor air inlet, the cyclone fan is rotated along the circumferential direction. As the polluted air and water rotate together, active mixing and stirring can be induced to improve the purification efficiency. In addition, the contaminated air is crushed through a plurality of outlets formed in the cyclone fan in the process of exiting the cyclone fan and put into the water to maximize contact with water. As a result, it is possible to maximize the mixing of the discharged air and water while reducing the input resistance of the polluted air into the water.

Next, according to the present invention, a cyclone guide crossing between the cyclone fan and the cyclone fan is formed, and the contaminated air inside the hollow tube is discharged through the adjacent cyclone fan in the process of turning and discharging through the cyclone fan. It is possible to prevent the rotational force from being canceled by colliding with each other, and through this, continuous mixing and stirring can be carried out by allowing the rotational power of the air and water discharged through each cyclone fan to be continuously rotated without losing the rotational power. and can promote the inhalation of external polluted air.

Next, in the present invention, when the cyclone guide is spirally formed in a direction corresponding to the rotational direction of the discharge air stream, the contaminated air is rotated and discharged through each cyclone fan, and the contaminated air and water are mixed and rotated. The rotational force of the discharge air stream discharged from the cyclone fan of can be induced to be discharged out of the water more smoothly.

Next, in the present invention, a cyclone fan formed in a branch pipe disposed in the center among a plurality of branch pipes is composed of a sun cyclone fan, and is formed in a branch pipe surrounding the branch pipe disposed in the center. The cyclone fan is composed of a planetary cyclone fan in which the discharge port is formed in the opposite direction to the sun cyclone fan and the air discharged in the opposite direction rotates in the opposite direction. It is arranged in a surrounding shape and operates in the same direction as the driving direction of the planetary gear system so that the rotation of each other can be accelerated when the external air is discharged and rotated. At this time, the cyclone guide is formed across each planetary cyclone fan to prevent the rotational force from being offset when the contaminated air is rotated and discharged through each planetary cyclone fan. In this way, the sun cyclone fan and the planetary cyclone fan rotate and discharge in opposite directions to accelerate the rotational force. It prevents the rotational force from being offset by colliding, and as a result, it creates a powerful rotational force on the outside of the body, which can be expected to further promote the mixing and agitation of polluted air and water. have.

Next, in the present invention, the hollow tube is arranged eccentrically from the main body to further expand the area of the vacuum unit inside the main body. As described above, when the area of the vacuum part is widened, the vacuum suction force acts more strongly, so that the suction improvement effect of the outside air can be expected, and it is possible to induce the rapid discharge of the purified air.

Next, according to the present invention, the water splash prevention plate is coupled along the horizontal direction in a form that surrounds a part of the hollow tube to prevent the water inside the main body from flowing into the vacuum outlet by the vacuum suction force of the vacuum device. In particular, according to the present invention, the water splash prevention plate is made of a sloping plate having one side high and the other side low, so that moisture separated from the air by weight flows along the sloping surface, so that it can be easily recovered to the bottom surface of the main body.

Next, the present invention has a wider diffusion than the hollow tube and a plurality of distribution tubes, so that a large amount of air can be injected at the same time. The total length of the perimeter of the outdoor air inlet, which is a path for moving from the inside to the outside, is maximized, so that when the polluted air is put into the water, the bottleneck can be significantly reduced. Therefore, since a larger amount of polluted air can be put into the water per unit time, there is an advantage in maximizing the purification efficiency.

Disclosed is a water filter for air purification that can significantly improve purification efficiency by introducing a larger amount of polluted air into the water by reducing the bottleneck phenomenon when external polluted air sucked by the vacuum suction force is put into the water. do.

For the above purpose, the present invention includes a main body 100 , a hollow tube 110 , a branch pipe 120 , and a vacuum unit 130 .

2a) and 2b), the main body 100 according to the present invention is a hollow body configured to be sealed inside, and is filled with water (W) up to a predetermined water level inside, and external polluted air is provided on one upper side. The outside air inlet 101 is formed, and the other side is connected in communication with an external vacuum device (not shown) providing a vacuum suction force and a vacuum outlet 102 is formed so that purified air is discharged.

It is preferable that the main body 100 has a cylindrical shape so that, after being put into water and purified, the purified air discharged out of the water moves in a spiral direction and then discharged to a vacuum outlet.

The body 100 may be made of various materials such as metal or synthetic resin, and preferably made of a transparent or semi-transparent material so that the inside can be checked from the outside with the naked eye.

The hollow tube 110 is a hollow column of a predetermined length with an empty inside and both ends are open, and is vertically disposed inside the body.

The upper end of the hollow tube 110 is connected in communication with the outside air inlet, the external polluted air is vacuum sucked by the vacuum suction force of the vacuum device, and the lower end is spaced apart at a predetermined height from the water surface filled in the body. and placed

The branch pipe 120 is a hollow pipe that is branched in a plurality of vertical and radial directions from the lower end of the hollow pipe, the lower part is submerged in water to a predetermined height, and the lower end of which is outdoor air into which contaminated air is introduced into the water. It consists of an inlet 121 .

In the following description, a branch pipe disposed in a vertical direction from the lower end of the hollow pipe is referred to as a "first branch pipe" 120, and a branch pipe branched in a radially downward diagonal direction is referred to as a "second branch pipe 120". ')", the outdoor air inlet at the lower end of the first branch is referred to as the "first outdoor air inlet 121", and the outdoor air inlet at the lower end of the second branch is referred to as the "second outdoor air inlet (121'). In addition, the branch pipe refers to the first branch pipe 120 and the second branch pipe 120 ′ at the same time, and the outdoor air inlet also refers to the first outdoor air inlet 121 and the second outdoor air inlet 121 ′ at the same time.

The vacuum unit 130 is formed between the vacuum outlet 102 and the outdoor air inlets 121 and 121 ′, and a vacuum suction force by a vacuum device (eg, a vacuum motor) acts to pass through the outdoor air inlet 121 . It is a space part where a vacuum suction force acts so that a polluted air is put into water and purified, and then introduced into the vacuum outlet 102 .

The operating principle of the water filter according to an embodiment of the present invention including the main body 100, the hollow tube 110, the branch pipes 120 and 120 ′, and the vacuum unit 130 as described above will be briefly described below. same as

First, when the vacuum device (not shown) is operated, the vacuum unit 130 inside the main body is vacuumed through the vacuum discharge unit 102 by the vacuum suction power to raise the water inside the main body. When the water is pulled up, the water and contaminated air inside the branch pipes 120 and 120 ′ escape into the water through the outdoor air inlets 121 and 121 ′, mix with water, and the pollutant source is adsorbed and dissolved in water, and light air flows out of the water. escapes into a vacuum. The water, which was pulled up, falls down due to its own weight as much as the escaped air, and the escaped air passes through the vacuum unit and is discharged out of the body through the vacuum discharge unit 102 . When the water and polluted air of each branch pipe escape into the water, a vacuum is also formed in the branch pipes 120 and 120 ′ and the hollow pipe 110 communicating with the branch pipe to suck the polluted air through the outside air inlet 101 . has a working principle.

As shown in Figure 1a), a water filter in which a hollow tube is vertically disposed inside the body so that the lower end is submerged in the water by a predetermined depth inevitably generates resistance in the process of passing the water surface when polluted air is introduced into the water, causing a bottleneck. Due to the stagnation caused by the phenomenon, the amount of air that can be injected into the water per unit time is limited. Therefore, in order to achieve the desired suction efficiency, it is inevitable to increase the diameter of the hollow tube, which is the path through which the polluted air passes.

When the diameter of the hollow tube 110 in the inner center of the main body 100 shown in FIG. 1A is widened, the area submerged in water is expanded so that the amount of polluted air injected into the water per unit time can be increased. However, as the diameter of the hollow tube increases in the limited internal space of the main body, the area of the vacuum unit 120 inevitably becomes narrower, and as the area of the vacuum unit becomes narrower, the vacuum suction power is lowered, so that the external polluted air is sucked and purified. The exhaust of the exhausted air is not smooth. In order to prevent such a problem, the body should also be widened in proportion to the diameter of the hollow tube, which is not appropriate because it is accompanied by problems that it is not easy to move, carry, store, etc. as the body grows.

Next, there is a method of connecting a plurality of water filters in parallel as a method of securing the amount of polluted air introduced into the water per unit time.

Referring to FIG. 1b), for example, three water filters 100, 100', 100″ are provided, but each vacuum unit 130, 130′, 130″ is connected to communicate with each other so that external polluted air is removed. By simultaneously inhaling through the outdoor air intakes 1210, 1210', 1210″ of each water filter, it is possible to secure a path through which as much air as possible passes, allowing a larger amount of polluted air to be introduced into the water per unit time. However, this method can be effective in suction efficiency, but has fatal disadvantages in space utilization and cost in that several water filters (each body and component) must be prepared.

As shown in Fig. 1c), when a vacuum force is applied to the vacuum unit and polluted air is put into the water through the outdoor air inlet, the air absorbs the entire mass of water inside the outdoor air inlet at once, unless a strong vacuum suction force acts. It escapes first along the outer wall circumference of the outdoor air inlet where the vacuum force acts first. The conclusion is that the passage through which the polluted air passes is not the total area of the outdoor air inlet, but the outer wall circumference (the length of the outdoor air inlet).

In the water filter for air purification according to the present invention, a plurality of branch pipes 120 and 120 ′ are branched from the lower end of the hollow pipe in the vertical and radial directions so that the lower part is submerged into the water by a predetermined depth, and a plurality of outdoor air inlets 121 and 121 ′). By maximizing the total length of the perimeter of the outside air inlet, which is a path for the contaminated air and the outside air inlet to move from the inside of the hollow tube to the outside as it is submerged in the water, it reduces the bottleneck so that a larger amount of polluted air can be put into the water. That is, it can be seen that making multiple branch pipes in a certain area rather than a single large-area hollow pipe is significantly longer than the total length of the perimeter of the outdoor air inlet. In addition, the space and action of the vacuum part are significantly increased through the blank space between the branch pipes.

For example, as shown in FIGS. 2a) and 2b), in the present invention, seven branch pipes 120 and 120 ′ are branched from the bottom of the hollow tube submerged in water along the vertical and radial directions, and seven outdoor air inlets submerged in water. By allowing the polluted air to be introduced into the water at the same time from (121 and 121'), the bottleneck is significantly reduced, and a larger amount of polluted air per unit time can be injected into the water for purification.

As described above, according to the present invention, a plurality of branch pipes are branched from the lower end of the hollow pipe so that the lower part is submerged in water by a predetermined depth, and the outdoor air inlets 121 and 121 ′ that become a movement path of contaminated air from the plurality of branch pipes 120 and 120 ′. ), the purification efficiency can be significantly improved by securing a plurality, and in particular, since the size of the main body 100 is not expanded or a plurality of main bodies are not connected in parallel, movement, portability, and storage can be made easily.

Since the conventional general air purifier uses a physical filtering method that purifies the polluted air through a filter, heavily polluted air (for example, polluted air containing oil, smoke, and odors generated during roasting or tobacco) is applied. When exposed to smoke) for a long time, the contamination level of the filter is inevitably deteriorated, and the life of the filter is shortened.

Since the water filter for air purification according to the present invention uses water as a means for purifying polluted air, it is exposed for a long time to polluted air containing oil, smoke and odors generated during roasting, or air with a high degree of pollution such as cigarette smoke. Even if it is cleaned, the purification efficiency does not decrease, and the maintenance and repair work can be completed by washing the components such as the body and hollow tube while replacing the water inside the body after using it for a certain period of time. The efficiency is remarkably excellent, and it has the advantage of minimizing the cost for maintenance and the waste of manpower.

Next, as shown in FIGS. 3a) and 3b), the cyclone fans 122 and 122' for introducing the vacuum-sucked polluted air into the water are formed at the lower ends of the branch pipes 120 and 120' submerged in water according to the present invention.

The cyclone fans 122 and 122' are formed with discharge ports 123 and 123' inclined in a radial direction so that the vacuum-sucked polluted air can be introduced while turning in the circumferential direction when it is introduced into the water.

When the contaminated air is rotated and discharged along the spiral direction through the discharge ports 123 and 123', the water inside the main body is rotated and the contaminated air and water rotate together, thereby inducing active mixing and stirring, thereby improving the purification efficiency. In addition, as water and polluted air rotate, vacuum suction and discharge are naturally performed, so that the input resistance of air is greatly reduced. In addition, in the process of exiting the cyclone fan, the contaminated air is crushed finely through the plurality of outlets 123 and 123' formed in the cyclone fan and put into the water, thereby maximizing the contact with the water. As a result, it is possible to maximize the mixing of the discharged air and water while reducing the input resistance of the polluted air into the water.

If the discharge port is not inclined, the power to rotate the water inside the body cannot be provided when the polluted air is introduced into the water, so the mixing and agitation of the polluted air and water cannot be smoothly performed. Since it is discharged out of the water after staying for a relatively short time, the purification efficiency may be reduced. Moreover, as large bubbles are formed in the water in the process of discharging the purified air out of the water, a loss occurs in which the area in which the contaminated air can come into contact with the water is reduced by the area of the bubbles, which is undesirable.

In the following description, the cyclone fan at the lower end of the first branch pipe is referred to as "first cyclone fan 122", and the cyclone fan at the lower end of the second branch pipe is referred to as "second cyclone fan 122'". The outlet of the first cyclone fan is referred to as a “first outlet 123”, and the outlet of the second cyclone fan is referred to as a “second outlet 123′”. In addition, the cyclone fan simultaneously refers to the first cyclone fan 122 and the second cyclone fan 122', and the outlet refers to the first outlet 123 and the second outlet 123' at the same time.

On the other hand, according to an embodiment of the present invention, when the polluted air is rotated and discharged through the outlets 123 and 123' of the cyclone fans 122 and 122' disposed in the water, the air discharged through the adjacent cyclone fan as shown in FIG. A problem in which rotational force is offset by collision may occur.

5a) to 5c) are schematic exemplary views showing a cyclone guide crossing between a cyclone fan and a cyclone fan according to an embodiment of the present invention for solving the above problems.

First, as shown in FIG. 5a ), the cyclone guide 140 according to an embodiment of the present invention is a first cyclone guide 1401 surrounding the first outdoor air inlet 121 at the lower end of the first branch pipe 120 . and a second cyclone guide 1402 crossing between the second outdoor air inlet portions 121 ′ at each lower end of two adjacent second branch pipes 120 ′ surrounding the first branch pipe.

In order to prevent the contaminated air discharged from the first cyclone fan 122 from colliding with the contaminated air discharged from the adjacent second cyclone fan 122', the first cyclone guide 1401 naturally has a predetermined height. It is formed in a cylindrical shape with

In addition, the second cyclone guide 1402 is formed to extend from the outer peripheral surface of the side surface of the first cyclone guide 1401 in a plurality along the radial direction, each of the second cyclone fan (122') through the contaminated air When the air is rotated and rotated while the polluted air and water are mixed, the rotational force of the discharge air flow discharged from each second cyclone fan 122' is summed up so that the outermost inside the body can rotate strongly. It is formed in a spiral shape in a direction corresponding to the direction of rotation.

That is, in the cyclone guide 140 according to an embodiment of the present invention, as shown in FIG. 5c , the contaminated air inside the hollow tube is branched into each branch pipe, and the first cyclone fan 122 along the spiral direction. The first cyclone fan 122 and each second cyclone fan 122' by preventing the rotational force from being offset by colliding with the air discharged through the adjacent second cyclone fan 122' in the process of turning and discharging. Continuous mixing and agitation can be performed by continuously rotating with a constant rotational force without losing the rotational force of the airflow and water by the discharged air discharged through the ventilator, and the intake of external polluted air can be promoted.

In addition, the rotational force of the discharge air flow discharged from each of the second cyclone fans 122 ′ is added to the outermost part of the main body to strongly rotate, thereby forming a strong spiral air flow to each of the second cyclone fans 122 . '), it produces the effect of improving the rotational force of the discharge air stream, and provides the effect of more active intake of polluted air, mixing of polluted air and water, and discharge of purified air.

Next, a cyclone fan and a cyclone guide according to another embodiment of the present invention will be described with reference to FIGS. 6a) and 6b).

First, FIG. 6a) is an exemplary view showing a general planetary gear system. The planetary gear system refers to a planetary gear system in which a plurality of planet gears are arranged in a form wrapped around a sun gear inside a ring gear, and the rotational force transmitted from the sun gear fixed to the drive shaft causes the planetary gear system. It refers to a power transmission system in which a planet gear is rotated and a ring gear is revolved by the planet gear.

The present invention can utilize the power transmission principle of such a planetary gear system to accelerate rotation of each other when external air is discharged from the cyclone fan and rotates.

Referring to FIG. 6b ), in the present invention, the cyclone fan formed in the first branch pipe 120 is composed of a sun cyclone fan 124 , and surrounds the first branch pipe 120 . The cyclone fan formed in the second branch pipe 120 ′ may be composed of a planet cyclone fan 125 .

Here, the planetary cyclone fan 125 is preferably formed in the direction of the discharge port in the opposite direction to the sun cyclone fan 124 so that the discharge outside air rotates in the opposite direction.

When the directions of the outlets of the sun cyclone fan 124 and the planetary cyclone fan 125 are opposite to each other, the outdoor air discharged from each planetary cyclone fan 125 collides with the outdoor air discharged from the sun cyclone fan. Thus, the rotational force can be continuously rotated without being offset, and when external air is discharged from each of the sun cyclone fan 124 and the planetary cyclone fan 125 and rotates, the effect of accelerating rotation can be expected.

In addition, as shown in FIG. 6b ), a cyclone guide 130 ′ crossing between each planetary cyclone fan 125 is formed so that the rotational force is not offset between each planetary cyclone fan 125 in the present invention.

The cyclone guide 130 ′ is spirally formed in a direction corresponding to the rotational direction of the discharge air flow to prevent each rotational force from being canceled when the contaminated air is rotated and discharged through each planetary cyclone fan 125 . It is preferable to consist of

As described above, the sun cyclone fan 124 and the plurality of planetary cyclone fans 125 surrounding the sun cyclone fan are rotated and discharged in opposite directions to accelerate the rotational force, and the cyclone guide is a partition wall between each planetary cyclone fan. (130′) is formed to prevent the air discharged from each planetary cyclone fan from colliding with each other to cancel the rotational force. It can also allow the purified air to be discharged out of the water more smoothly.

Next, in the present invention, the hollow tube 110 may be arranged eccentrically from the main body 100 .

As described above, the vacuum part 130 is a space part where a vacuum suction force for sucking in polluted external air acts, and is used as a path for the purified air discharged out of the water to be discharged to the vacuum outlet 102 . do.

If the area of the vacuum unit 130 is increased, a stronger vacuum suction force is applied to the inside of the main body, so that the suction of the outside polluted air and the discharge of the purified air can be made more quickly and smoothly.

Here, in order to widen the area of the vacuum unit 130 , there may be a method of extending the diameter of the body 100 or reducing the diameter of the hollow tube 110 . As the diameter of the body increases, the overall volume increases. This is not preferable, and since a bottleneck may occur when the diameter of the hollow tube is reduced, it is not preferable.

In the present invention, the maximum width of the vacuum unit 130 is secured inside the limited body by eccentrically disposing the hollow tube 110 on one side of the body.

7a) and 7b) are schematic exemplary views for comparing the change in the width of the vacuum unit 130 according to the change in the position of the hollow tube 110 . As shown in Fig. 7a), when the hollow tube 110 is disposed in the inner center of the main body 100, the vacuum unit 130 has a constant width d1 throughout the interior, whereas the hollow tube 110 as shown in Fig. 7b) has a constant width d1. When 110) is arranged eccentrically on one side from the main body, the maximum width d2 of the vacuum unit 130 is expanded to secure an area where a strong vacuum suction force acts, and active suction of polluted air and purified air by stronger vacuum suction force can lead to the rapid release of

7a) and 7b), reference numeral 103 is a communication part that connects the upper end of the hollow tube 110 and the outdoor air inlet 101 to guide the external polluted air to be introduced into the hollow tube.

Next, Figures 8a) to 8c) is a schematic illustration for explaining a water splash prevention plate according to an embodiment of the present invention.

Since the main body 100 according to the present invention is sealed so that a vacuum unit 130 is formed between the vacuum outlet and the outdoor air inlet, when the vacuum suction force is strong, the purified air bounces off the water surface when it is discharged out of the water. Water may be drawn into the vacuum outlet along with the purified air.

If the water splashing out of the water enters the vacuum discharge unit 102, damage to the vacuum device or deterioration in durability is inevitable, as well as the amount of water charged inside the body is gradually reduced, such as foreign substances in polluted air, fashionable components, etc. The performance that can purify is inevitably reduced.

The water splash prevention plate 150 is formed to prevent this problem in advance, and the hollow tube 110 along the horizontal direction is located at a position higher than the water level in the lower part of the vacuum part where the vacuum suction force acts and the water level inside the body. ) is formed to surround the outer circumferential surface, and is preferably formed in the direction in which the suction rotational force of the air acts by the vacuum suction force.

In addition, the water splash prevention plate 150 is a hollow tube so that the outer wall of the water splash prevention plate 150 and the hollow tube 110 and the vacuum unit 130 can serve as a passage through which air rotates and flows. It is preferable to wrap only a part of the outer circumferential surface of 110, for example, in the form of a half donut, and by this structure, there is an air inlet 160 in the body so that the vacuum suction force can be sufficiently transmitted to the lower portion as shown in FIG. 8a). is secured

In the air vacuum sucked through the air inlet 160, water droplets that bounce off the water surface when the purified air is discharged are mixed. The air mixed with water droplets rotates along the passage formed by the splash-proof plate 150 as shown in FIG. 8a), and at this time, the water droplets, ie, moisture, fall to the splash-proof plate 150 by the weight.

Here, the water splash prevention plate 150 has one side high and the other side low so that moisture separated from the air by weight flows along the slope and is recovered to the bottom surface of the body. Although not shown in the drawings, the water splash prevention plate may be formed in the form of a perforated plate in which a plurality of drain holes are formed.

In addition, the shape of the water splash prevention plate 150 and the width of the air intake port 160 may vary according to the position of the hollow tube 110 . In particular, the air intake 160 serves as a passage for the delivery of vacuum suction force and the discharge of purified air, and as shown in FIG. 8c ), when the hollow tube 110 is eccentric from the body, the air intake 160 is wide. It is possible to more effectively transmit the vacuum suction force and induce the purified air to be discharged out of the water more smoothly.

Next, a water filter with improved purification efficiency according to another embodiment of the present invention will be described with reference to FIGS. 9a) and 9b). In FIG. 9A , reference numeral “W” denotes water filled in the body.

The water filter according to another embodiment of the present invention is characterized in that it is possible to remarkably improve the purification efficiency by simultaneously injecting a remarkably large amount of polluted air into the water per unit time.

For the above purpose, the present invention includes a main body 200 , a hollow tube 210 , a diffusion unit 220 , a distribution tube 230 , and a vacuum unit 240 .

First, the main body 200 is a hollow body configured to be sealed inside, and water (W) is filled therein to a predetermined water level, and an outside air inlet 201 through which polluted air from the outside is introduced is formed on one upper side, and , the other side is connected in communication with an external vacuum device (not shown) that provides a vacuum suction power and a vacuum discharge unit 202 for discharging purified air is formed.

It is preferable that the main body 200 has a cylindrical shape so that the purified air discharged from the water after being put into the water and purified is rotated in a spiral direction and then discharged to the vacuum outlet.

The body 200 may be made of various materials such as metal or synthetic resin, and preferably made of a transparent or semi-transparent material so that the inside can be checked from the outside with the naked eye.

The hollow tube 210 is a hollow column of a predetermined length having an empty inside and both ends are open, and is vertically disposed inside the body.

The upper end of the hollow tube 210 is connected in communication with the outside air inlet, the external polluted air is vacuum sucked by the vacuum suction power of the vacuum device, and the lower end is spaced apart at a predetermined height from the water surface filled in the body. and placed

The diffusion unit 220 is connected in communication with the lower end of the hollow tube and has a hollow structure with an empty interior, and serves as a passage through which contaminated air can be smoothly supplied from the hollow tube to the plurality of distribution tubes.

The distribution pipe 230 has an open upper end and an open lower end, and is in the form of a hollow tube with an empty inside. The lower end is composed of an outdoor air inlet 231 for introducing the contaminated air introduced into the water from the diffusion unit 220 into the water.

Here, the distribution pipe 230 is arranged in plurality from the diffusion unit 220, and a large amount of contaminated air introduced into the diffusion unit through the hollow tube is distributed to the plurality of distribution tubes 230 and simultaneously into the water. allow it to be put in.

As a method of reducing such a bottleneck, there is a method of injecting contaminated air into the water using the cyclone rotation method described above. There is a way to secure a lot of paths for the contaminated air to pass through as a number of outdoor air inlet parts are placed in the water.

At this time, it is preferable to configure the interval between each distribution pipe 230 to be constant so that the vacuum suction force evenly acts on the submerged distribution pipe 230 and the outdoor air inlet 231 .

As a method for securing a plurality of distribution tubes, there may be a method of increasing the area of the diffusion unit. However, if the area of the diffusion portion increases in the limited internal space of the body, the area of the vacuum portion becomes relatively narrow, so that the vacuum force acts. As the road (passage) becomes narrower, the suction efficiency decreases. Therefore, it is very important to properly adjust the area of the diffusion unit 220 and the area of the vacuum unit 240 in the limited internal space of the body 200, and secure the total circumference of the outdoor air inlet while ensuring a sufficient width of the vacuum unit. It can be said that the diameter of the distribution pipe, the distance between the distribution pipe and the distribution pipe, or the arrangement shape are important.

For example, as shown in FIG. 9B ), the distribution tube 230 may have a cylindrical shape having the same diameter and length so that the vacuum suction force can be equally applied to each of the plurality of distribution tubes. In addition, when arranging a plurality of distribution pipes 230 having the same diameter on the bottom surface of the diffusion portion 220, it is preferable that the diffusion portion has a hexagonal cross-section so as to minimize the idle space. Due to the nature of the circle, if circles of the same size are arranged on a plane at regular intervals, the shape of the entire circumference is hexagonal. Therefore, when the diffusion unit 230 is configured in a hexagonal shape, a sufficient number of vacuum units 240 is secured while maintaining a constant distance between the distribution pipes 230 under the same area (the operation passage of the vacuum unit). of the distribution pipe 230 can be arranged.

The vacuum unit 240 is formed between the vacuum outlet 202 and the outdoor air inlet 231, and the vacuum suction force by the vacuum device (for example, a vacuum motor) acts to pass through the outdoor air inlet 231. It is a space part that allows polluted air to be introduced into the water and then purified and then introduced into the vacuum outlet 202 .

The principle of operation of a water filter according to another embodiment of the present invention including the main body 200, the hollow tube 210, the diffusion unit 220, the distribution tube 230, and the vacuum unit 240 as described above. A brief description is as follows.

First, when the vacuum device (not shown) operates, the vacuum unit 240 inside the main body is vacuumed through the vacuum discharge unit 202 by the vacuum suction power to raise the water inside the main body. When the water is pulled up, the water and contaminated air inside the distribution pipe 230 escape into the water through the outdoor air inlet 231, mix with the water, and the pollutants are adsorbed and dissolved in the water, and the light air is removed from the vacuum part outside the water. exits with At this time, the water that was pulled up falls down due to its own weight as much as the escaped air, and the escaped air passes through the vacuum unit and is discharged out of the body through the vacuum discharge unit 202 . When the water and polluted air of each distribution pipe escape into the water, a vacuum is also formed in the hollow pipe 210 communicating with the distribution pipe and the distribution pipe to suck the polluted air through the outside air inlet 231 It has an operating principle. .

The water filter for air purification according to another embodiment of the present invention includes a diffusion unit 220 and a plurality of distribution tubes 230 wider than the hollow tube 210, so that a large amount of air can be simultaneously injected, and each distribution tube The total length of the perimeter of the outdoor air inlet 231, which is a path for the contaminated air to move from the inside to the outside of the hollow tube, is maximized, so that the lower part of the can be significantly reduced. Therefore, since a larger amount of polluted air can be put into the water per unit time, there is an advantage in maximizing the purification efficiency. In addition, the narrower and larger the diameter of the distribution pipe, the longer the circumferential length of the outdoor air inlet 231 can be secured, and small air bubbles are formed, thereby increasing the efficiency.

The present invention described above is merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the forms recited in the above detailed description.

Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
