Description

Functional Air Cleaner Using Water Curtain Filter

The present invention is a functional air purifier using a water film filter, more specifically, by using the water film generated by the surface tension and capillary phenomenon of water as a filter to remove foreign substances in the air and at the same time to have a sterilization treatment capacity economical without the burden of frequent replacement of the filter The present invention relates to an air purifier that provides excellent air purification while ensuring a high quality.

As the industry develops, the problem of air pollution due to various soot is getting more and more serious. In particular, as China develops into a full-fledged industrialized country, various pollution problems are serious. However, various pollutants from China, especially fine dust, continue to cross over to Korea in a whistle wind, and the Meteorological Agency announces the concentration of fine dust several times a day.

Fine dust is a small substance that is invisible to our eyes and is a particulate matter with a diameter of 10 μm or less that floats or scatters in the air for a long time. Fossil fuels such as coal and petroleum are combusted, or come from exhaust gases from manufacturing and automobile fumes. They are adsorbed into the lungs through bronchial tubes and cause various waste diseases.

According to the National Institute of Environmental Research (2006), dust is divided into total dust, fine dust (PM 10) with a diameter of 10 µm or less, and ultra fine dust with a diameter of 2.5 µm or less (PM 2.5), depending on the particle size. Fine dust is composed of ionic components such as nitrate (NO3-), ammonium (NH4 +), sulfate (SO42-), carbon compounds, and elements compounds. The World Health Organization (WHO) Black carbon (BC) from diesel has been designated as a primary carcinogen. When exposed to fine dust for a long time, the immunity is rapidly lowered and can be exposed to various diseases such as cardiovascular disease, skin disease, eye disease, as well as respiratory diseases such as cold, asthma and bronchitis. In particular, ultrafine dust having a diameter of 2.5 μm or less easily penetrates deep into the bronchus and lungs in the human body and causes various diseases in the bronchus and lungs.

  Meanwhile, the World Health Organization (WHO) has proposed air quality guidelines for fine dust (PM10, PM2.5) since 1987, and in 2013, the International Agency for Research on Cancer under the World Health Organization (IARC). ) Was designated as a group 1 carcinogen (Group 1) confirmed to be carcinogenic to humans.

As such, the fine dust has a very harmful effect on the human body, the sales of air cleaners increased rapidly as the frequency of contamination by these fine dust has become more frequent in recent years.

Air cleaners provide cleaner air by removing harmful substances as well as foreign substances such as fine dust in the air by filtering the filter, and many related arts related to filter technology and sterilization technology using germicidal lamps have been published. .

1 is a side cross-sectional view schematically showing the overall configuration of an air purifier according to the present invention, Figure 2 is a perspective view showing the external configuration of the air purifier according to the present invention, Figure 3 is a view of the air purifier according to the present invention It is a cross section.

1 to 3, it can be seen that the air purifier according to the present invention basically includes a water tank 100, a connection chamber 200, and a sterilization chamber 300.

Referring first to the water tank 100, the water tank 100 of the present invention serves to serve as a primary gateway through which the outside air is introduced while serving as a fresh water or a reservoir of the filtering solution 10, and is limited in its shape. However, referring to the drawing, it is formed in a cuboid shape and takes a structure that can be stably supported on the floor where the air cleaner is disposed in a state in which the filtering solution 10 is accommodated.

At this time, the cover 130 is formed on the upper surface of the water tank 100 to be opened and closed to replace the filtering solution 10 according to a predetermined cycle.

The air inlet 120 is formed on one side of the upper portion of the portion in which the filtering solution 10 is accommodated, and serves to inject air. The air inlet 120 may be formed in the cover 130 as well as the side wall. It may also be formed on the support surface 160 extending from the top to the top.

The filtering solution 10 rises through the water film filter 110 by capillary action to cause a water film phenomenon in the water film filter 110. In general, the filtering solution 10 may be made of purified water or tap water. As will be described later, the filtering solution 10 may include a functional material in addition to water.

In addition, the auxiliary sterilization lamp 140 may be formed in a state partially contained in the filtering solution 10.

Auxiliary sterilization lamp 140 is to sterilize the filtering solution 10 containing the harmful components such as bacteria that purify the air and the residual, unlike the sterilization lamp 310 to be described later sterilize the air, an embodiment As one side is attached to the inner surface of the cover 130 as the other side is extended to the bottom is immersed in the filtering solution (10). The auxiliary germicidal lamp 140 may be made of a known UV lamp, in particular it needs to be waterproofed because it is immersed in the filtering solution 10 and is further wrapped in a protective tube such as a quartz tube to provide light (eg, visible light). To infrared) wavelength can be ensured high transmittance.

The water film filter 110 is disposed at one side of the inside of the tank 100 in which the filtering solution 10 is accommodated, preferably from the bottom of the water tank 100 so as to be soaked in the filtering solution 10, above the surface of the filtering solution. It takes a structure such as a standing sheet, panel or membrane extending up to. At this time, the water film filter 110 has a plurality of fine through holes and may be made of a material and a structure such as a non-woven fabric or a microfiber cloth through which a plurality of fine through holes are implemented.

A portion of the side wall of the water tank 100 in which the water film filter 110 stands is open to provide a space in which air passing through the water film formed in the water film filter 110 can move to the connection chamber 200. That is, the water film filter 110 is attached to cover the filter mounting surface 150 having one side wall, that is, the open area, which is open to the upper surface of the water surface of the filtering solution 10 among the side walls of the water tank 100.

The membrane filter 110 acts as a thin tube to provide a phenomenon that the filtering solution 10 may rise through the membrane filter 110, that is, a capillary phenomenon. The filtering solution 10, which is taken up through the water film filter 110, wets the surface and the back surface of the water film filter 110 and remains between the micro-holes. Particularly, the filtering solution 10 may be formed by the surface tension, which is inherent in water. ) Aggregates to form a kind of water film.

That is, the water film filter 110 filters the air passing through the water film by the filtering solution 10, that is, provides a foundation for filtering foreign substances and harmful substances of the air through the water film.

According to such a water film filter 110, the air purification while solving the above-mentioned problems compared to the known air purifier that can not only need the hassle and maintenance cost of frequent replacement of the filter, but also cause environmental pollution problems for the waste filter It provides the property to keep the function as it is.

The connection chamber 200 of the present invention is located between the water tank 100 and the sterilization filter 300 to be described later to perform the function of delivering the air passing through the water film filter 110 to the sterilization filter 300, the The shape is not limited and may be made of, for example, a pipe shape such as a pipe.

However, the water tank 100 and the sterilization filter 300 of the present invention are not shown in Figure 1, 2 and the like to smoothly purify the air while at the same time not to occupy a larger space than necessary and to promote the flow of air As described above, it is preferable that the sterilizing filter 300 is standing on the water tank 100. Accordingly, the connection chamber 200 has a housing shape, that is, a chamber structure having a predetermined space therein to deliver air while securing a sufficient physical volume capable of stably supporting the sterilization filter 300 in the upper portion of the water tank 100. It may be made of.

As described above, in order to pass through the air without remaining in the water film filter 110, an external force must act. For this purpose, the air cleaner of the present invention includes a fan 210.

The fan 210 provides an external force through which the air can move in the outward direction of the water tank 100 through the rotational force in the inside of the water tank 100, wherein the fan 210 is the water tank 100 and the connection chamber 200. It is possible to be mounted on at least one side of the sterilization chamber (300).

In particular, the fan 210 induces a dynamic flow of air in the sterilization chamber 300 while allowing the air to smoothly move from the water film filter 110 toward the connection chamber 200. It is more preferable to be mounted at one side of the connection chamber 200 which is an intermediate portion of the 300, more preferably at the boundary between the connection filter 200 and the sterilization filter 300.

In this case, the filtering solution 10 as well as the air in the water film filter 110 may be moved to the connection chamber 200 together with the size of the fan 210 to the intensity of the rotation speed. In this case, the filtering solution 10 is already Since the air is filtered, it may be in a contaminated state, and furthermore, the fan 210 may directly contact water to cause a breakdown.

In order to prevent such a problem, a peripheral wall of the fan 210, for example, as can be seen in Figure 1, the lower side of the fan 210 is formed with a blocking wall 220 extending to a predetermined length. The blocking wall 220 not only blocks the filtering solution 10 from entering the pan 210 and moves to the sterilization chamber 300, but more preferably, an end portion of the blocking wall 220 has a water tank direction (FIG. It can be extended to bend down to 1 criterion) to guide the water so that water can be restored back to the water tank direction.

Such a connection chamber 200 may have a variety of volumes and shapes according to the position and size of the sterilization chamber 300 and the water tank 100, as well as a single unit as well as a combination of the connection plate 230, etc. It is also possible to consist of a composite unit.

4 is a partial perspective rear view showing the germicidal lamp in accordance with the present invention.

The sterilization chamber 300 of the present invention performs a function of sterilizing the air introduced through the connection chamber 200, that is, the air purification mechanism of the present invention is applied through the water film filter 110 of the water tank 10. The first is to filter the foreign matter of the air and to sterilize the air secondary through the sterilization chamber 300.

Specifically, the sterilization chamber 300 is located on one side of the water tank 100, preferably on the upper side of the water tank 100 to secure the efficiency of the air flow path described above, and supports the connection chamber 200 through the medium. do. The sterilization chamber 300 is also made of a housing shape having a sufficient volume to perform a sterilization function and its shape is not particularly limited. In addition, one side (lower one side) of the sterilization chamber 300, the connector 340 for receiving air from the connection chamber 200 is connected to the connection chamber 200 and the other side of the sterilization chamber 300 (Upper one side) is discharged through the discharge port 350 to discharge the foreign matter as well as to discharge the sterilized air back to the outside.

The sterilization lamp 310 is mounted inside the sterilization chamber 300, and the sterilization lamp 310 may be made of a UV lamp like the auxiliary sterilization lamp 140 described above and may be formed of a light (sterilization lamp) such as titanium dioxide. It is also possible to incorporate a photocatalyst which performs a function such as antibacterial and deodorization by promoting a chemical reaction through light).

In particular, the sterilization chamber 300 of the present invention is divided into a plurality of partitions 320 at regular intervals along the air flow direction, that is, the height direction to form a plurality of spaces based on the partitions 320, An embodiment in which a germicidal lamp 310 is provided in each space is shown. In this case, air partitions 330 through which air flows are formed in each partition wall.

2 to 3, the sterilization lamp 310 extends in a direction parallel to the partition wall 320 so as to secure a sufficient contact area with the air introduced from the air outlet 330 as much as possible.

As a result, the air introduced from the connection chamber 200 may be sterilized through the sterilization lamp 310 of the sterilization chamber 300, and then the purified air may be discharged through the discharge port 350.

The flow of air by the air purifier of the present invention according to such a structure is summarized as follows with reference to FIG.

First, when the fan 210 is operated by a user's manipulation, air is introduced into the water tank 100 through the air inlet 120 of the water tank 100. The air introduced into the water tank 100 comes into contact with the water film filter 110. The foreign matters or harmful components in the air are removed while passing through the water film formed in the filtering solution 10 with the help of the rotational force of the fan 210.

At this time, the auxiliary sterilization lamp 140 sterilizes harmful components such as foreign substances and bacteria remaining in the filtering solution 10 to prevent the filtering solution from being left in a contaminated state.

The air passing through the water film filter 110 is also moved to the sterilization chamber 300 through the connection chamber 200 by the rotational force of the fan 210 and the sterilization lamp 310 provided in each space of the sterilization chamber 300. Sterilized by contact with

Finally, the air after removing the foreign substances and sterilization is discharged to the outside through the discharge port 350 can supply clean air to the space in which the air cleaner of the present invention is installed.

According to the air purifier according to the present invention, since only the filtering solution 10 needs to be replaced without the need for frequent replacement of the filter, the cost of the filter replacement is reduced and the problem of polluting the environment by the waste filter is minimized. It can provide cleaner air by removing foreign substances and sterilization.

Previously, the air inlet 120 may be penetrated to one side of the side wall of the cover 130 to the water tank 100, and ensures sufficient surface area to allow more outside air to flow into the water tank, as well as a connection chamber (to be described later) It is possible to form an additional configuration on top of the water tank 100 to provide a physical structure that can more stably support the 200 and the sterilization chamber (300).

1 and 2, the filter mounting surface 150 on which the water film filter 110 is mounted extends beyond the top of the water tank 100 to the bottom of the sterilization filter 300. In this case, one surface (front surface) of the connection chamber 200 may be connected, or may be one surface itself constituting the connection chamber 200.

In addition, the support surface 160 is extended from the upper portion of the water tank 100 to the lower portion of the sterilization chamber 300 at regular intervals from the filter mounting surface 150. At this time, the air inlet 120 is formed on the support surface 160 so that the air passing through the air inlet 120 is spaced between the support surface 160 and the filter mounting surface 150 as the fan 210 rotates. After passing through the membrane filter 110 may be moved to the filter mounting surface 150 is mounted.

According to such a structure, the water tank 100 may further include a support (that is, a support surface) serving to support the sterilization chamber 300, and at the same time, the air inlet 120 may be formed. By securing an additional sufficient area may provide an advantage to increase the amount of air filtered by introducing more outside air into the water tank (100).

Figure 5 is a side cross-sectional view showing a state in which the air inlet and the sterilization lamp in a zigzag arrangement according to the present invention.

As mentioned above, it is known that bacteria or viruses in the air can be sterilized smoothly when the air contacts the UV lamp itself or the photocatalyst provided in the UV lamp for at least several seconds (for example, 2 to 3 seconds). By the driving of the contact time is not secured, there is a probability that the air located in the sterilization chamber 300 exits the sterilization chamber 300 in an instant. In this case, more sterilization lamps 310 need to be disposed in the sterilization chamber 300 in order to prevent the sterilization power from dropping. However, in this case, the product price is inevitably increased.

In order to solve this problem, the air outlets 330 penetrated through the partition wall 320 of the present invention are penetrated in a staggered manner with respect to the space or each partition wall 320.

As can be seen from FIG. 5, for example, the air outlet 330 penetrates through the right portion of the partition wall 320 in the bottom space and the air outlet 330 in the center portion of the partition wall 320 in the middle space. ) Is penetrated and the air outlet port (or discharge port) penetrates to the right side of the partition wall 320 again in the uppermost space, and as a result, the air outlet port 330 is penetrated in a zigzag structure based on each space. .

In addition, the germicidal lamp 310 is also disposed around the air outlet 330 zigzag through, as a result, the germicidal lamp 310 is also arranged in a zigzag based on the space.

According to such a structure, as can be seen in Figures 1 and 2, the air passing through the sterilization chamber 300 is not easily discharged or moved out along the one-line line to form a vortex or force circulation in each space As a result, it is possible to secure more time for staying in the sterilization chamber 300, and consequently, the time for contacting the sterilization lamp 310 and air is also provided. At this time, the germicidal lamp 310 may be provided with a stainless mirror to increase the reflectance to further promote the sterilization action, thereby active treatment of the contact reaction with air.

In addition, the air outlet 330 may be provided with a blade 331 extending inclined so that the diameter becomes smaller downward.

The wing 331 has a small diameter in the peripheral side of the air outlet 330 but extends so that the diameter becomes wider at the end side, for example, the air is diffused from the lower first space to the middle second space. Can be. That is, the wing 331 allows the air to be widely distributed in the subsequent space instead of traveling in only one direction, resulting in a random circulation in the space to remain more in the space. Can be performed.

As described so far, the configuration and operation of the functional air cleaner using the water film filter according to the present invention have been expressed in the above description and the drawings, which are merely examples, and the spirit of the present invention is not limited to the above description and the drawings. Of course, various changes and modifications are possible without departing from the spirit of the present invention.
