Description

Air purifying device

Technical Field

The invention relates to an air purification device, in particular to an air purification device without replacing a filter.

Background

Generally, an air cleaner is a device for sucking air, filtering out impurities such as fine dust contained in the air, and discharging clean air.

Such an air cleaning apparatus is provided in a vehicle, home, or office and is used to clean air.

Generally, an air cleaning apparatus needs to be provided with a filter for filtering air. Such filters include dry filters in which impurities are filtered out using paper, cloth, or the like, and wet filters in which impurities are attached by allowing oils to permeate through fibers of iron, copper, or glass.

If the filter used in the air cleaning apparatus is not replaced in time, impurities attached to the filter increase, causing an increase in impedance when air is sucked, and even a path through which air flows is blocked.

Accordingly, an air cleaning apparatus has been developed, which removes impurities having a specific gravity greater than that of air using centrifugal force, and thus can be permanently used without replacing a filter.

An example of such a swirling-type air cleaning device is disclosed by japanese patent laid-open No. 2001-73890 (hereinafter referred to as 'prior art document 1').

As shown in fig. 9, the conventional swirling-type air cleaning device disclosed in prior art document 1 includes a main body 2 connected to an air introduction duct 10 and having an inner diameter gradually expanding toward one side, an air discharge portion 6 fixed to a lower portion of the main body 2 and having an upper end extending toward an inner side of the main body 2, a rotation pin 4 provided at an inlet 3 of the main body 2 and converting an inflow air into a swirling flow, a trap portion 7 formed between the upper end of the air discharge portion 6 and a lower end of the main body 2 and trapping foreign substances, and a foreign substance discharge port 8 formed at a portion of the trap portion 7 and discharging foreign substances.

Accordingly, the air flowing in through the inlet 3 of the body 2 forms a rotational flow by the rotation pin 4, and by the rotational flow, the foreign substances having a higher specific gravity than the air move along the inner wall of the body 2 due to a centrifugal force and are caught in the catching part 7, and the foreign substances caught in the catching part 7 are discharged to the outside through the foreign substance discharge port 8. At the same time, the air from which the impurities have been removed in the center of the swirling flow is moved to a desired place by the air discharge portion 6.

However, the conventional swirling-type air cleaning device disclosed in the aforementioned prior art document 1 utilizes a single swirler, and thus has limitations in terms of efficiency and performance.

Detailed Description

Hereinafter, an air cleaning apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 8, an air cleaning apparatus according to an embodiment of the present invention includes: a housing 110 provided on a path through which air flows from the outside; an assembly composed of cyclone units 200 arranged in a plurality of rows and columns, the cyclone units 200 being disposed at the housing 110 and filtering air; and an air-directing member that directs air flowing into the assembly.

The housing 110 is composed of an upper plate 112 disposed on a path in which air flows from the outside, a lower plate 114 spaced apart from the upper plate 112, and a partition wall 116 formed to connect an edge of the upper plate 112 and an edge of the lower plate 114.

In order to provide the cyclone unit 200 inside the upper plate 112, a plurality of upper plate through holes 113 are formed in a row in the upper plate 112. The lower plate 114 is disposed in parallel with the upper plate 112, and a plurality of lower plate penetration holes 115 are formed in lines at corresponding positions of the upper plate 112 in order to dispose the cyclone units 200.

Meanwhile, a partition wall 116 is formed between the edge of the upper plate 112 and the edge of the lower plate 114. Among them, it is preferable that the upper end of the partition wall 116 is connected to the edge of the upper plate 112 and the lower end of the partition wall 116 is connected to the edge of the lower plate 114 so that there is no portion protruding to the outside. Among them, the discharge port 118 is formed at a portion of the partition wall 116 and discharges the foreign substances discharged from the cyclone unit 200 to the outside. Meanwhile, since the impurities discharged through the cyclone unit 200 reach the bottom of the lower plate 114 by gravity, the discharge port 118 is preferably formed at the lower portion of the partition wall 116.

The swirling units 200 arranged in rows and columns include: a cyclone body 210 penetrating the upper plate 112 and having an open upper portion and a closed lower portion; an air discharge pipe 220 penetrating the lower plate 114 and having an upper end extending to the inside of the cyclone body 210; a plug 230 located at the center of the inlet of the cyclone body 210 and dispersing air flowing in from the upper portion in a radius direction; a plurality of vanes 240 which are bent in a radius direction from the plug 230 and extend to an inner wall of the cyclone body 210 to swirl air flowing into the cyclone body 210; and an opening 212 formed on a lower circumferential surface of the cyclone body 210 to discharge impurities separated from the air flowing into the cyclone body 210 by a centrifugal force.

The cyclone body 210 is formed in a cylindrical shape to facilitate the formation of a swirling flow inside the cyclone body 210, and has an open upper portion and a closed lower portion. The cyclone body 210 is formed to penetrate through an upper plate 212. Also, although the lower portion of the cyclone body 210 is closed, in order to discharge the air from which the foreign substances have been removed in the cyclone body 210, the air discharge pipe 220 penetrates the lower portion of the cyclone body 210 and extends to the inside of the cyclone body 210. A space is formed in a radial direction between a lower portion of the cyclone body 210 and an upper portion of the air discharge pipe 220 extending to the inside of the cyclone body 210, and impurities are trapped in the space. Meanwhile, an opening 212 for discharging foreign substances caught in the space is formed at a lower portion of the cyclone body 210. Wherein the opening 212 formed at the lower portion of the cyclone body 210 needs to be formed to be spaced apart from the upper end of the air discharge pipe 220 sufficiently so as not to interfere with the air from which the foreign substances are removed moving inside the cyclone body 210.

The air discharge pipe 220 has a cylindrical shape and is formed to penetrate through the lower portion of the cyclone body 210 and extend to the inside of the cyclone body 210. Therefore, the outer diameter of the air discharge pipe 220 is formed smaller than the inner diameter of the cyclone body 210. The air discharge pipe 220 is fixed to the cyclone body 210 and inserted into the lower plate penetration hole 115 of the lower plate 114. Therefore, the lower portion of the air outlet duct 220 is exposed to the outside of the lower plate 114.

The plug 230 is located at the center of the inlet of the cyclone body 210 for dispersing air flowing from the upper portion to allow the air to flow in a radius direction. The peg 230 may be located at the centre of the inlet of the cyclone body 210 by means of a plurality of vanes 240 extending to the centre of the cyclone body 210. In order to smoothly flow the air flowing in through the inlet of the cyclone body 210, the plug 230 is preferably formed in a streamline shape such as a cone or a hemisphere. Meanwhile, in order to disperse the air flowing into the plug 230 and prevent the air flowing along the outer circumferential surface of the plug 230 from forming a vortex at the rear end portion of the plug 230 to cause a pressure drop to disturb the flow of the air, the rear end portion of the plug 230 is preferably formed in a streamline shape of a hemispherical shape or a conical shape.

The plurality of vanes 240 are bent in a radial direction from the plug 230 and extend to the inner wall of the cyclone body 210, so that air flowing into the cyclone body 210 forms a swirling flow. In order to make the air flowing into the cyclone body 210 flow along the swirling flow and make the impurities in the air easily separated by the centrifugal force, it is necessary to consider the shape and size of the vane 240.

The air guide member is an air flow guide 310 for guiding air flowing into the assembly, and is installed at an upper end of the cyclone body 210 of the cyclone unit 200. Here, the air flow guide 310 is integrally formed with the cyclone unit in the present embodiment, but the air flow guide 310 may be combined or assembled as needed.

The upper end of the air flow guide 310 is formed in a quadrangular cross section and the lower end is formed in a circular cross section. As described above, since the upper end of the air flow guide 310 is formed in a quadrangular cross section, a blank space is not generated when the plurality of air flow guides 310 are arranged in a matrix. The cross section of the lower end of the airflow guide 310 is formed in a circular shape and corresponds to the upper end of the cyclone body 210. Therefore, the air flow guide 310 may smoothly guide the air flowing into the air cleaning apparatus of the present invention to the cyclone unit.

The cyclone bodies 210 are preferably arranged at a prescribed distance from each other in the particle discharge space inside the casing 110 so as not to obstruct the discharge of the particle flow from the cyclone bodies 210. At this time, the inlets at the upper end of the cyclone body 210 are necessarily spaced apart from each other on the upper plate 112, and therefore, the inlets are blocked by the upper plate 112, and such a blocked structure causes a problem of causing a pressure loss to the air flow. The plurality of air flow guides 310 are provided to prevent the aforementioned problems, thereby minimizing the pressure loss.

Meanwhile, in order to prevent the air flow guides 310 arranged in rows and columns from being separated to the outside, a quadrangular frame 410 is provided at the upper end of the housing 110. Wherein the frame 410 provided at the upper end of the outer shell 110 has a quadrangular cross-section to correspond to the shape of the outer shell 110.

Preferably, the frame 410 is formed with meshes 412 so that the airflow guide parts 310 are aligned in a row at a correct position. The mesh 412 is preferably formed in a size corresponding to the shape of the airflow guide 310.

Hereinafter, an operation of the air cleaning apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

First, air flowing from the outside flows into the cyclone body 210 through the airflow guide 310. At this time, since the air flow guide portion 310 is formed to span the entire cross section of the air inflow path, all the air flowing into the cyclone body 210 is purified.

Next, the air flowing into the cyclone body 210 reaches the plug 230 and is dispersed in the radial direction. At this time, the air dispersed in the radial direction forms a swirling flow by the plurality of blades 240 and continues to travel.

When the swirling flow is formed, impurities having a large specific gravity in the air are moved in a radial direction from the center by a centrifugal force.

The impurities moving in the radius direction move along the inner circumferential surface of the cyclone body 210, and the impurities moving along the inner circumferential surface of the cyclone body 210 are discharged into the casing 110 through the opening 212.

The foreign substances discharged to the inside of the casing 110 are discharged to the outside through a discharge port 118 formed on a partition wall 116 of the casing 110.

Meanwhile, the air from which the foreign substances have been removed in the cyclone body 210 moves to a place where the air from which the foreign substances have been removed is required through the air discharge pipe 220.
