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

[0002]

2. Description of the Related Art In a conventional home 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 an ion-type cleaning device in which dust and odor components in the air are charged, for example, to the + side, and the dust is attracted to the − side electrode and collected with a paper towel.

[0003]

In the filter type cleaning device, the filter is clogged relatively quickly, so that the filter must be replaced frequently, which is not only troublesome but also increases the cost of the filter. . Further, the filter has a problem that the pressure loss is large because the activated carbon and the fiber are almost completely clogged without any gap, and the fan for sucking air must use a large capacity, so that the filter becomes expensive.

In an ion-type cleaning device, if the air flows at a high speed, dust or the like charged on the positive side is discharged to the outside together with the air without being attracted to the negative side.
It was difficult to forcibly suck and flow air. Therefore, there is a problem that only the air very close to the cleaning device is cleaned, and the air outside the cleaning device 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]

In order to solve the above-mentioned problems, according to the present invention, a wind tunnel having an air inlet and an air outlet, and air surrounding the wind tunnel being introduced into the wind tunnel from the inlet. A fan for sucking and discharging from the outlet, and an opening provided in the wind tunnel and formed continuously over the entire circumference as an ejection port, and water or liquid for purifying the air is supplied to the wind tunnel. An air purifying device having a nozzle that jets out radially at a substantially right angle to the flow direction of air inside the nozzle, the nozzle comprises an upper first member and a lower second member, and the first member And the second member are opposed to each other to form the opening. On the side of the second member opposed to the first member, a protrusion having an inner side inclined is provided. Spout diagonally upward, water or liquid Changing the ejection direction of, and is characterized in adjusting the thickness of the water or liquid is ejected.

[0007]

In the air cleaning apparatus 1, as shown in FIG. 1, the air sucked into the wind tunnel 11 by the fan 14 passes through the water or liquid ejected from the nozzle 15 to the outside through the outlet 13a. Is discharged to Dust and odor components in the air dissolve in the jetted water or liquid, so that the air is cleaned. As shown in FIGS. 2 and 3, the nozzle 15 ejects water or liquid substantially at right angles to the flow direction of the air in the wind tunnel 11 and radially, so that the water or liquid is disc-shaped into the wind tunnel 11. collide. Therefore, wind tunnel 1
1 only needs to have a length sufficient to receive at least the disc-shaped water or liquid, so that the overall height of the air cleaning device 1 can be reduced. Since the inside of the projection 27 forming the spout 30 is inclined, water or liquid is spouted horizontally and obliquely upward. This makes it possible to increase the thickness of the jetted water or liquid. The water or liquid discharged from the discharge port 13a is collected in the collection part 19c of the collection tank 19.

[0008]

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 household air purifier 1 to which the present invention is applied. The air purifying device 1 is small and portable, and a cap-shaped rectifying plate 12 is provided above a relatively small cylindrical wind tunnel 11 for rectifying air. The current plate 12 is provided with a downward suction port 12a for sucking outside air. Further, a funnel portion 13 is provided below the wind tunnel 11 so as to prevent water and liquid jetted into the wind tunnel 11 from scattering around. The lower end of the funnel 13 has a wind tunnel 1
A discharge port 13a for discharging the air in 1 is provided.

[0010] Inside the wind tunnel 11, a fan 14
When the fan 14 is driven, air around the air purifying device 1 is sucked into the wind tunnel 11 from the inlet 12a of the rectifying plate 12, and is discharged from the outlet 13a of the funnel 13 to the outside. Is discharged.

At the center of the wind tunnel 11, a nozzle 15 is disposed below the fan 14, and is connected to a discharge pipe 17 of a submersible pump 16 disposed outside the wind tunnel 11. As shown in FIG. 2, the nozzle 15 is composed of a fixed part 21 attached to the discharge pipe 17 with a screw, and a movable part 22 that can move up and down. In the fixing part 21,
A water chamber 23 connected to the discharge pipe 17 is formed, and a columnar support portion 24 is protruded from the center of the water chamber 23. Water room 23
The surface facing the moving part 22 is open, and the support part 24 is provided with an internal screw 25.

The moving portion 22 is disposed to face the open surface of the water chamber 23. A protrusion 27 having a triangular cross section is provided on the outer periphery of the disk-shaped bottom portion 26 over the entire circumference.
A column-shaped boss 28 is provided at the center of 6. A screw shaft 29 is provided upright at the center of the boss 28. By moving the screw shaft 29 into the inner screw 25 of the fixed part 21, the moving part 22 is attached so as to be able to move up and down.

The tip of the projection 27 faces the outer peripheral wall of the water chamber 23, and a water outlet 30 is formed between the fixed part 21 and the moving part 22. Since the spout 30 is opened over the entire circumference of the nozzle 15, water is spouted radially from the spout 30 as shown in FIG. That is, the water spouted from the nozzle 15 has a disk shape, and the air passes therethrough. If you want to change the thickness of the disc-shaped water or change the state of the water jet,
The width d of the ejection port 30 may be changed by rotating the moving unit 22. As the width d increases, the jetted water changes from a mist state to a water droplet state and finally to a flowing water state.

In the present embodiment, the projection 27 forming the ejection port 30 is formed.
Is inclined, so that water is spouted horizontally and diagonally upward. As a result, the thickness of the disc-shaped water can be increased, the contact area between air and water increases, and the ability to clean the air improves. Note that the ejection port 30 may be formed of only flat upper and lower surfaces without providing such an inclination. That is, the shape may be such that the protrusion 27 is removed from the bottom portion 26 of the moving portion 22.

In FIG. 1, the submersible pump 16 is disposed in the water supply section 19a of the recovery tank 19 below the wind tunnel 11. As a result, the water in the water supply unit 19a is sucked up by the pump 16 and jetted into the wind tunnel 11 via the discharge pipe 17 and the nozzle 15. The recovery tank 19 includes the water supply unit 19a and the partition unit 19b.
And a collection unit 19c. Here, for example, if a filter (not shown) is attached to the partition part 19b and the water in the recovery part 19c is purified by the filter and returned to the water supply part 19a, the water can be circulated and used. .

In the air purifying apparatus 1, for example, when a start button (not shown) is pressed, the fan 14 and the submersible pump 16 are driven. Thereby, the surrounding air is sucked into the wind tunnel 11 and the water supply unit 19a
The clean water inside is blown into the wind tunnel 11. Then, the sucked air passes through the jetted clean water and is discharged to the outside.

At this time, the dust and odor components contained in the air are dissolved in the water, and when the air is discharged to the outside, the air becomes clean air containing no such components. Conversely, the clean air discharged from the air cleaning device 1 is added with an appropriate amount of moisture, so that it can be used as a humidifier. Furthermore, when the outside air temperature is high such as in summer, the heat of vaporization of water is taken from the sucked air to lower the temperature, so that there is also an effect that the cool air is discharged.

In the air cleaning device 1, the nozzle 1
Since the air only passes through the disc-shaped water spouted from the fan 5, the resistance applied to the air is small, and the fan 14
For example, it is possible to use an inexpensive one having a small capacity such as an axial fan. Furthermore, since the water ejected from the nozzle 15 is in a disk shape substantially perpendicular to the flow direction of the air, the wind tunnel 11 has at least a length sufficient to receive the disk-shaped water, that is, the thickness of the disk-shaped water. It is only necessary that the length is substantially the same or slightly larger than that, so that the height of the entire air cleaning device 1 can be reduced.

In the above-described embodiment, water is used for purifying the air. However, it is possible to add perfume and fragrance to the air, and it is also possible to use an appropriate liquid other than water. It is possible.

[0020]

[Effects of the Invention] As described above, according to the present invention,
Water or a suitable liquid is ejected radially at a right angle to the flow direction of the air, and the air passes through the jet, so that it is possible to purify a wide range of air with a simple configuration. In addition, the height of the entire air cleaning device can be reduced because the wind tunnel needs to be at least as long as or slightly longer than the thickness of the jetted water or liquid. Further, an opening is formed by opposing the upper first member and the lower second member, and a projection whose inner side is inclined is provided on a side of the peripheral edge of the second member facing the first member. Therefore, water or liquid can be ejected horizontally and obliquely upward, changing the direction of ejection of water or liquid, making it possible to increase the thickness of ejected water or liquid, and making air and water or The contact area of the liquid increases, and the ability to purify air can be improved.
