Description

{AIR CLEANER WITH WATER CURTAIN}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner, and more particularly, to an air cleaner having a water curtain structure using a water film formed by spraying water in a water tank on a water surface.

Generally, an air purifier is a sanitary device that filters contaminants or fine dust in contaminated air and discharges cleaned air into the room while forcibly circulating the air through the room.

Such an air cleaner can be classified into a filter system and a water system.

The filter type air cleaner uses a filter that catches dust and VOC gas, respectively, but it has a disadvantage that it has to be replaced every predetermined time.

Activated carbon filters are widely used for reducing VOC gas. In this case, it is necessary to periodically replace the activated carbon filter.

A disk-type air cleaner using water is also called an air washer, and dust containing air is introduced into a rotating disk to attach dust.

However, the disk type air cleaner using such water has a problem that the air cleaning effect is inferior.

On the other hand, when it rains, the atmosphere is cleaned because the dust and VOC gas in the air are swept away or dissolved by the rain. By using this feature, it is possible to obtain a good cleaning effect by injecting air containing dust into water and discharging it from the water due to density difference.

In order to realize this, it is possible to devise a method in which a rotating body formed with an air chamber or an air collecting part in which air can stay is partially rotated while being immersed in water. However, when air is put into water or when water is lifted into the rotating body There is a problem in that a large energy is consumed and noise is generated when air is discharged or water is dropped.

That is, the intensity of the water 10 is highest in the first spray part 122 and the intensity of the water 10 in the order of the second spray part 124 to the third spray part 124 is small Can be.

The arrangement of the spray unit 120 takes into consideration a situation in which the air introduced into the water tub 110 gradually becomes cleaner as the water sprayed by the spray unit 120 passes through each stage. That is, since the impurities contained in the air decrease as the inflow air moves from the front end to the rear end in the multi-stage structure, the n-th spray unit 124 is blown with less intensity than the (n-1) It is possible to purify the air with only the water particles. Thus, the air cleaning efficiency of the air cleaner can be improved.

Meanwhile, at least a part of the upper part of the water tub 110 is opened so that air can freely flow in and out. In this case, ambient air can be introduced and discharged in a natural manner.

However, in the present invention, an air inlet 130 for introducing air and an air outlet 140 for discharging air may be separately provided in a part of the water tub 110.

Specifically, the water tub 110 may include an air inlet 130 having a fan for forcibly introducing the air outside the water tub 110 to one side. In addition, the water tub 110 may include an air discharge unit 140 formed at a predetermined size to discharge air inside the water tub 110 on the other side. The air discharge unit 140 may include a first air discharge unit 140 formed on the other side of the water tub 110 facing the air inlet unit 130.

In this case, the air outside the water tub 110 is forced to flow into the water tub 110, and can be purified by the water particles blown up by the spray unit 120, The water can be discharged to the outside of the water tub 110 through the water pipe 140.

Here, the first air discharge unit 140 may be equipped with a fan for forcibly discharging purified air from the inside of the water tub 110. Accordingly, it is possible to induce an increase in the flow rate of the air circulating inside and outside the water tub 110, thereby providing an environment that can purify the air outside the water tub 110 more quickly.

The water particle collecting part 150 is formed on the other side of the water tub 110 to collect the water particles discharged together with the purified air from the first air discharging part 140. Here, it is preferable that the water particle collecting part 150 is disposed in parallel with the first air discharging part 140 and the water tray 110 in the direction transverse to the longitudinal direction.

The water particle collecting part 150 may be equipped with a fan for forcibly collecting the water particles discharged from the first air discharging part 140. Accordingly, it is possible to provide an environment in which the discharged water particles can be guided to flow quickly into the water tub 110.

With such a structure, it is possible to prevent the external humidity of the water in the water tub 110 from rising, and the water particles can be introduced into the water tub 110 again and reused as the water sprayed by the spray unit 120 .

3 is a cross-sectional view of an air cleaner having a water curtain structure according to another embodiment of the present invention.

Specifically, as shown in FIG. 4, the water guide member 160 may be formed at a position higher than the water surface a in the water tub 110 as a water-bearing member. That is, the water guide member 160 can guide water falling freely after being sprayed by the spraying unit 120.

In other words, the free falling water falls on the surface of the water guide member 160, and the dropped water may fall on the water surface a after a certain time. Thereby, it is possible to reduce the noise generated by water falling on the water surface (a).

The water guide member 160 of FIG. 4 has a rectangular cross section, but is not limited thereto and may be embodied in various forms.

For example, the water guide member 160 may be formed such that its tip is inclined at a predetermined angle? Toward the water surface a so that free-falling water flows down along the surface. Specifically, the end of the water guide member 160 may be formed to be inclined toward the lower right side, or may be inclined toward the lower left side.

As another example, the water guide member 160 may include a bent portion 131, a portion of which is bent downward.

With this structure, it is possible to minimize the noise generated when the falling water falls on the water surface (a) after being sprayed by the spray part (120).

Although not shown in the drawing, the water guide members 160 may be arranged in a multi-stage structure with a plurality of water guide members 160 spaced downward. For the sake of reference, the downward direction refers to a direction toward a position where the spray part 120 in the water tub 110 is disposed.

Specifically, the water guide member 160 includes a first water guide member (not shown) to (n-1) water guide members (not shown) spaced apart from the upper end of the multi- (N is a natural number of 3 or more)

Here, the distances between the first water guide member and the nth water guide member are preferably equal to each other.

In the multi-stage structure, the (n-1) water guide member may be formed such that the vertical center line of the end toward the water surface (a) crosses the n-th water guide member.

That is, in order for the n-th water guide member to retract the water flowing down along the surface of the (n-1) water guide member, the vertical center line passes through a part of the n-th water guide member, Member can be arranged.

As a result, the height at which free-falling water falls on the water surface (a) can be reduced to reduce noise.

In addition, although not shown in the drawing, the water guide member 160 may be formed so that its central portion is curved downward. In other words, the central portion of the water guide member 160 may be formed to be recessed downward so that water falling off the surface freely falls and collects.

Here, a water guide sub-member (not shown) may be provided under the water guide member 160 to guide water falling from the water guide member 160.

At this time, the end of the water guide sub-member may be inclined at a predetermined angle toward the water surface a so that water falling from the water guide member 160 flows along the surface. Specifically, the end of the water guide sub-member may be formed to be inclined toward the lower right side, or may be formed to incline toward the lower left side.

The water guide member 160 may have a through hole (not shown) for passing the collected water to the water guide sub member.

The through holes may be formed through the water guide member 160 in the thickness direction.

The through hole 135 may be formed to have a smaller diameter as it goes down. Thereby, the passing water can be more safely dropped to the water guide sub-member.

The through hole 135 may have a groove (not shown) formed in a spiral shape on the inner side so that water passing therethrough passes therethrough.

With such a structure, the passing water flows down along the groove portion, and the descending speed gradually decreases due to the rotational force, and flows down along the surface of the water guide sub member in a state where the speed is reduced, It is possible to further reduce the noise generated when falling.
