[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifying apparatus which is inexpensive and can have high performance, and more particularly to an air purifying apparatus which is suitable for use in a household cleaning apparatus in consideration of portability.

[0002]

2. Description of the Related Art In a conventional household air purifier, activated carbon or fiber such as polypropylene is used as a filter, and forcibly sucked air is passed through the filter to remove dust and odor contained in the air. There is a filter-type cleaning device that removes the like. In addition, there is also an ion-type purifier in which dust and odor components in the air are charged, for example, to the + side, attracted to the − side electrode, and collected with a paper towel.

[0003]

In the filter type purifier, since the filter is clogged relatively quickly, the filter must be replaced frequently, which is not only troublesome but also has a problem that the cost of the filter is high. . Further, the filter has a problem that the pressure loss is large because the activated carbon and the fibers are almost completely clogged with no gap, and the fan for sucking the air must use a fan having a large capacity.

In an ion-type purifier, if the air flows at a high speed, dust or the like charged on the + side is discharged to the outside together with the air without being attracted to the − side. Can not be sucked and flowed. Therefore, there is a problem that the air outside the purifier is only cleaned, and the air outside the purifier cannot be cleaned.

[0005] The present invention solves the above-mentioned problems, and it is possible to purify a wide range of air at low cost and improve the recovery rate of clean water. An air purifying device is proposed.

[0006]

According to the first aspect of the present invention, an air intake passage and an exhaust passage are provided inside a wind tunnel, and the intake passage and the exhaust passage are provided. A direction changing unit for changing the direction of the flow of air is provided between the air passage and the air passage; a fan for sucking external air is provided in the wind tunnel; and water for purifying the air is sprayed to the suction passage. A nozzle is provided, an air outlet is provided on an upper side of the discharge passage, a water outlet is provided on a lower side of the wind tunnel, and the fan is provided only on the discharge passage side of the wind tunnel. It is a feature. According to another aspect of the present invention, an air intake passage and an exhaust passage are provided inside the wind tunnel, and a direction change unit that changes the direction of air flow is provided between the intake passage and the exhaust passage. A fan for sucking external air into the wind tunnel, a nozzle for spraying water for purifying the air into the suction passage, and an air outlet at an upper side of the discharge passage. A water outlet is provided at a lower side of the wind tunnel, and an air passage cross-sectional area of the suction passage is smaller than an air passage cross-sectional area of the discharge passage.

[0007]

In FIG. 1, the dirty air sucked into the suction passage 13 is cleaned through the water sprayed by the small-diameter nozzle 16 or the large-diameter nozzle 17, and is purified by the air outlet 21 of the discharge passage 14. Is discharged from the outside. The water sprayed in the suction passage 13 collides with the wall surface of the funnel 23 and is discharged from the water outlet 24.

At this time, since the direction of the air flowing through the suction passage 13 and the discharge passage 14 is changed by 180 degrees, water droplets in the air flowing through the suction passage 13 are caused to flow by the inflow inertia at the time of suction and the gravity, so that the wall surface of the funnel 23 is formed. Collisions easily. Furthermore, since the air passage cross-sectional area B of the discharge passage 14 is larger than the air passage cross-sectional area A of the suction passage 13, the flow velocity of the air in the discharge passage 14 decreases. Therefore, the water is almost completely discharged from the water discharge port 24 because the force for raising the water is weakened.
That is, the water recovery rate is improved.

[0009]

Next, an embodiment of an air purifying apparatus according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the configuration of a home air purifying apparatus 1 according to the present invention. The air purifying device 1 is small and portable, and the inside of a relatively small cylindrical wind tunnel 11 is partitioned by a partition plate 12 into two right and left sides in the figure. The partition plate 12 is provided so as to be closer to the right side than the center.
As shown in FIG. 2, the narrow space on the right side is an air intake passage 13 and the wide space on the left side is an air discharge passage 14. That is, the cross-sectional area A of the passage of the air in the suction passage 13 is smaller than the cross-sectional area B of the passage of the air in the discharge passage 14.

A cap-shaped rectifying plate 15 is provided at the upper end of the suction passage 13 for rectifying the air to be sucked in.
An air inlet 15A is provided at its lower end. In addition, a small-diameter nozzle 16 and a large-diameter nozzle 17 are attached to the upper side of the suction passage 13 in order to spray water over the entire air passage portion.

The small diameter nozzle 16 and the large diameter nozzle 17 are connected to a switching cock 18. The switching cock 18 is connected to a submersible pump 20 via a pipe 19. The small-diameter nozzle 16 is used, for example, when atomizing water particles, such as a mist, and spraying it, and the large-diameter nozzle 17 is used, for example, when coarsely spraying water particles such as a droplet. Switching of these nozzles 16 and 17 is performed by a switching cock 18.

The upper end of the discharge passage 14 has a large opening and is provided with an air discharge port 21 from which the purified air is discharged to the outside. Further, a fan 22 is mounted on the upper side of the discharge passage 14, and by rotating the fan 22, air is sucked in from the air inlet 15A.

A funnel 23 is provided at a lower portion of the wind tunnel 11, and a water outlet 24 is provided at a lower end thereof. A tank 25 is arranged below the wind tunnel 11, and is divided by a partition plate 26 into a water supply unit 27 and a recovery unit 28. Clean water is stored in the water supply unit, and the above-described submersible pump 20 is disposed here. The water discharged from the water discharge port 24 of the wind tunnel 11 is collected by the collection unit 2 of the tank 25.
Collected in 8.

In the air purifying apparatus 1, for example, when a start button (not shown) is pressed, the fan 22 and the submersible pump 20 are driven. As a result, wind tunnel 1
The air around 1 is sucked into the suction passage 13 from the air suction port 15 </ b> A, and the clean water in the water supply unit 27 is sprayed into the suction passage 13. Accordingly, the sucked air passes through the sprayed clean water for a relatively long distance. At this time, the dust and odor components contained in the air are dissolved in the water and removed, thereby purifying the air.

Since the water that has fallen in the suction passage 13 has a large specific gravity, it is discharged from the water discharge port 24 at the lower end of the funnel 23 and is recovered in the recovery section 28 of the tank 25. The air purified when passing through the suction passage 13 is:
Since the specific gravity is low, the air discharge port 14
1 to the outside. Further, in this example, as described above, since the cross-sectional area B of the discharge passage 14 is larger than the cross-sectional area A of the suction passage 13, the force for pulling up water from the discharge passage 14 is reduced. Therefore, the water that has fallen in the suction passage 13 collides with the wall surface of the funnel 23 and is easily discharged from the water discharge port 24 without being pulled up. In this way, in the air purifying apparatus 1, it is possible to completely separate the water for purifying the air from the air and recover most of the water.

In this air purifying apparatus 1, the fan 2
2 is arranged near the air outlet 21, the air collides with the wall surface of the funnel 23 and the air inlet 15 is smaller than when the fan 22 is arranged near the air inlet 15 </ b> A.
The components that return to the A side are reduced, and the occurrence of turbulence is reduced. Therefore, the air flows easily, and it becomes possible to inhale and purify more air.

Further, since the air purifying apparatus 1 is provided with the small-diameter nozzle 16 and the large-diameter nozzle 17, the size and amount of water particles sprayed into the suction passage 13 when humidifying or purifying the air. Can be appropriately adjusted. In addition,
It is also possible to provide three or more types of nozzles having different diameters.

[0019]

As described above, according to the present invention, an air intake passage, an air discharge passage, and a direction change portion are provided inside the wind tunnel, and a fan for sucking external air is provided in the wind tunnel, and the air is discharged. A nozzle for spraying water for cleaning into the suction passage is provided, an air outlet is provided on an upper side of the discharge passage, and a water outlet is provided on a lower side of the wind tunnel. Furthermore, the air passage cross-sectional area of the suction passage is formed smaller than the air passage cross-sectional area of the discharge passage.

Therefore, according to the present invention, a wide range of air can be purified with a simple configuration. Further, since water and air can be completely separated, there is an effect that the recovery rate of water is improved.
