Description

Air purifier using water filter {AIR PURIFIER USING WATER FILTER}

An embodiment of the present invention relates to an air purifier using a water filter.

An air purifier is a generic term for a device that cleans the air by filtering out dust or bacteria in the air, and it varies according to the type of built-in filter.

Since contaminated air can harm human health and lower the quality of life, various types of air purifiers are used to prevent this.

Some air purifiers are equipped with only the function of purifying air, while others are added as a single function to air conditioners.

In addition, it is known that air purifiers range from small to large, depending on their size.

On the other hand, the air purifier is known to have a primary function of filtering out dust or bacteria in the air as described above, and thus cleaning of the filter, especially filter replacement, is known to be of the utmost importance.

In the case of a large air purifier, since the interior space is large, it is possible to implement a structure to open the front case and replace the filter like an air conditioner, but in the case of a small size, it is possible to replace the filter due to space limitations. It is not easy to implement the structure.

Even if it is easy to replace the filter, if the replacement cycle is too fast, inconvenience in use may occur.

As a result, in the case of a small air purifier, it must have a compact shape to improve the aesthetics of the exterior due to the product characteristics, and have an efficient structure for air cleaning. In particular, the filter can be easily replaced and the replacement cycle can be extended. A structure to ensure that there is a need to be added, but the need for a small air purifier equipped with these items emerges from the point that a small air purifier that satisfies these items has not yet been disclosed.

The housing 200 may have a substantially cylindrical shape, and in this embodiment, the structure of the housing 200 is not limited to a cylindrical shape, but may be changed to a regular cube, a rectangular parallelepiped, or various polygonal structures.

A conical protrusion 210 may be formed at a portion of the housing 200 corresponding to the lower end of the air intake pipe 300 of the bottom surface of the housing. Air sucked through the lower part of the air intake pipe 300 is discharged toward the bottom surface of the housing 200, at which time the discharged air hits the protrusion 210 and the liquid contained in the housing 200 (water, fragrance, etc.) It can help to better disperse or spread.

The air intake pipe 300 is vertically disposed in the housing 200 and may serve to guide air sucked through the air intake unit 100 to the lower portion (bottom surface) of the housing 200.

The air intake pipe 300 may include a plurality of unit intake pipes, which are vertically arranged from an upper portion of the housing 200 to a lower portion of the housing 200 and each have a cylindrical structure having a different diameter. The unit suction pipe may be arranged such that a unit suction pipe having a gradually smaller diameter is disposed from the top to the bottom of the housing 200, and a step portion due to a difference in diameter may be formed between the unit suction pipes connected to each other among the plurality of unit suction pipes. have.

For example, as shown in Figure 2, the air intake pipe 300 is a first unit suction pipe 310, a second unit suction pipe 320, a third unit suction pipe 330, a fourth unit suction pipe 340, A fifth unit suction pipe 350 and a sixth unit suction pipe 360 may be included. The first unit suction pipe 310 is connected to the air suction unit 100 so that air sucked from the air suction unit 100 may be introduced, and the uppermost portion of the first to sixth unit suction pipes 310 to 360 It may be positioned at, that is, positioned on the upper side of the housing 200. Thereafter, the second to sixth unit suction pipes 320 to 360 may be sequentially arranged vertically in a row toward the bottom surface of the housing 200.

That is, the first unit suction pipe 310, the second unit suction pipe 320, the third unit suction pipe 330, the fourth unit suction pipe 340, the fifth unit suction pipe 350, and the sixth unit suction pipe 360, in that order. As a result, the diameter can be gradually reduced.

Accordingly, the air intake pipe 300 may better allow the air sucked in through the air intake unit 300 to be introduced, and as the air flow width is narrowed, the air discharge speed at the lower end of the air intake pipe 300 is increased. It is possible to increase the speed of hitting the protrusion 210, and accordingly, air dispersion and diffusion by the protrusion 210 may be made better.

In addition, a step portion may be formed between unit suction pipes adjacent to each other (or connected to each other) due to a difference in diameter between the first to sixth unit suction pipes 310 to 360, for example, as shown in FIG. 2, A first step portion S1 is formed between the first and second unit suction pipes 310 and 320, and a second step portion S2 is formed between the second and third unit suction pipes 320 and 330, A third step S3 is formed between the third and fourth unit suction pipes 330 and 340, and a fourth step S4 is formed between the fourth and fifth suction pipes 340 and 350. A fifth step S5 may be formed between the fifth and sixth suction pipes S350 and 360, respectively.

Accordingly, after the fifth to first unit filter plates 360 are sequentially stacked from the bottom of the housing 200 to the top, and the air intake pipe 300 is inserted and disposed, a liquid (water or When the fragrance) is filled, the fifth to first unit filter plates 360 rise toward the top by the buoyancy force, and at this time, they can be arranged spaced apart from each other by being fixed in a state caught on each step according to the arrangement position and diameter. have.

A plurality of filter holes for filtering contaminants of air discharged through the air intake pipe 300 may be formed in the first to unit filter plates 410 to 450, respectively. For example, as shown in FIG. 3, a plurality of first filter holes 412 are formed in the first unit filter plate 410, and a plurality of second filter holes ( 422 is formed, a plurality of third filter holes 432 are formed in the third unit filter plate 430, a plurality of fourth filter holes 442 are formed in the fourth unit filter plate 440, A plurality of fifth filter holes 452 may be formed in the fifth unit filter plate 450.

Here, the diameters of the first to third filter holes 412 to 452 may be formed differently for each of the first to fifth unit filter plates 410 to 450, and more specifically, the first to fifth unit filter plates In 410 to 450, a unit filter plate having a gradually larger filter hole diameter may be disposed from the top to the bottom of the housing 200. That is, the diameter of the first filter hole 412, the second filter hole 422, the third filter hole 432, the fourth filter hole 442, and the fifth filter hole 452 may be gradually increased in order. have.

In this way, the first to fifth unit filter plates 410 are disposed so that the filter hole gradually decreases from the bottom of the housing 200 to the top, so that dust contained in the external air discharged to the bottom of the housing 200 As the dust of the medium-sized particles is gradually removed, the purified air may rise upward of the housing 200.
