[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.

The present invention has been made to solve the above-mentioned problem, and proposes an air purifying apparatus which is inexpensive and can purify a wide range of air.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, in the present invention, a wind tunnel having an air inlet and an air outlet, and air around the wind tunnel being sucked into the wind tunnel from the air inlet and discharged. A fan for discharging from the outlet, a water supply means for supplying water for purifying air into the wind tunnel, and a water spraying means for spraying the water over the entire air passage in the wind tunnel;
A water storage tank with an inflow opening for water discharged from the wind tunnel opening upward, a lid movably mounted below the inflow opening to open and close the inflow opening, and a water storage tank with a predetermined angle A pressing means for pressing the lid toward the inflow port when tilted as described above, wherein the inflow port is closed by the lid when the water storage tank is tilted to a predetermined angle or more.

[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 into the suction passage 13 collides with the wall surface of the funnel 23, is discharged from the water discharge port 24, and is stored in the water storage tank 25.

[0008] As shown in FIG.
Is inclined by a predetermined angle θ or more, the interval L between the hook portion 38 of the pendulum 34 and the water outlet 24 becomes narrower, and the lid 31
4 is pressed against the lower surface side. Thereby, the water storage tank 25 is completely sealed, so that it is possible to prevent the internal water from leaking to the outside.

[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 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. Water sprayed in the wind tunnel 11 falls from the water outlet 24. A water outlet 24 is provided below the funnel 23.
A closed water storage tank 25 is provided except for.
The water dropped from the water discharge port 24 is stored in a water storage tank 25, sucked by a pump 20 via a suction pipe 26, and supplied to a small-diameter nozzle 16 or a large-diameter nozzle 17.

In the water storage tank 25, a lid 31 for closing the water outlet 24 from below is disposed. One end of the lid 31 is rotatably supported by a rotation shaft 32 provided on a side wall of the water storage tank 25. A hole 33 of an appropriate size is provided on the plate surface of the lid 31, and a pendulum 34 is movably inserted therein.

The pendulum 34 has a spherical pivot 36 at the upper end of a rod 35 and a spherical weight 37 at the lower end of the rod 35. In the middle part of the rod 35, a disc-shaped or polygon-shaped pressing portion 38 is provided so that an appropriate distance L is opened from the lower end surface of the water discharge port 24. The pivot 36 of the pendulum 34 is rotatably supported by an appropriate angle in all directions by a support portion 39 provided below the funnel portion 23.

If the air purifying apparatus 1 is placed on a horizontal surface 27 such as a table in a normal state, the lid 31
Is hooked on the press hook portion 38 of the pendulum 34 so that an appropriate gap is formed between the lid 31 and the water discharge port 24. This allows water sprayed in the wind tunnel 11 to flow into the water storage tank 25.

In the air purifying apparatus 1, when a start button (not shown) is pressed, for example, the fan 22 and the pump 20 are driven. Thereby, the air around the wind tunnel 11 is sucked into the suction passage 13 from the air suction port 15 </ b> A, and the water in the water storage tank 25 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 dropped in the suction passage 13 has a large specific gravity, it is discharged from a water discharge port 24 at the lower end of the funnel 23 and collected in a water storage tank 25. Inhalation passage 13
When passing through the air, the purified air has a low specific gravity and rises along the discharge passage 14 to be discharged from the air discharge port 21 to the outside. 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.

Further, as shown in FIG. 2, even when the air purifying device 1 is tilted for some reason, the pendulum 34 maintains a vertical state. In this case, the distance L between the pressing portion 38 of the pendulum 34 and the water outlet 24 is smaller than in the normal state. In other words, the lid 3 is
1 is pressed to the water discharge port 24 side.

When the air purifying apparatus 1, that is, the water storage tank 25 is inclined to a predetermined angle θ, the lid 31 abuts on the lower end surface of the water discharge port 24, and the water storage tank 25 is completely sealed. Therefore, the water in the water storage tank 25 is prevented from leaking out. Even if the air purifying device 1 is tilted any more, for example, completely falls down, the water outlet 24
Remains sealed with the lid 31, so that the water storage tank 25
Water in the inside is prevented from leaking to the outside.

Although FIG. 2 shows the case where the water storage tank 25 is tilted to the right in the figure, the pendulum may be tilted in any other direction, for example, to the left or the front-rear direction in the figure. Since the distance L between the pressing hook 38 and the water outlet 24 becomes narrower, the lid 31 is pressed against the water outlet 24 by the pressing hook 38 so that the water storage tank 25 is completely sealed. Therefore, even if the water storage tank 25 inclines or falls in any direction, it is possible to prevent the water in the water storage tank 25 from leaking out.

[0023]

[Effect of the Invention] As described above, the present invention provides an air purifying apparatus for purifying air with water sprayed in a wind tunnel, comprising a water storage tank for storing water discharged from the wind tunnel, and an inlet. A lid movably mounted below the inlet for opening and closing, and a pressing means for pressing the lid toward the inlet when the water storage tank is tilted at a predetermined angle or more, wherein the water storage tank is tilted to a predetermined angle or more. The inlet is closed by a lid when the lid is closed.

Therefore, according to the present invention, even if the air purifying device falls down due to an earthquake or the like, the water in the water storage tank does not leak out, so that the surroundings can be used without being polluted. There are effects such as becoming.
