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 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 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 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 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, in the present invention, a wind tunnel having an air inlet and an air outlet, and air surrounding the wind tunnel are introduced into the wind tunnel from the suction side. A fan for sucking and discharging from the discharge side, a nozzle for spraying water or liquid for purifying the sucked air into an air passage of the wind tunnel, and collecting the sprayed water or liquid. A collection tank for the, provided on the discharge port side of the wind tunnel, and a water guiding unit for guiding the sprayed water or liquid into the collection tank, the lower end of the water guiding unit is located in the recovery tank, The water guide section is provided with a discharge port for discharging air upward from a lower end thereof.

[0007]

In the air purifying apparatus 1, as shown in FIG. 1, the air sucked into the wind tunnel 11 by the fan 14 passes through the water sprayed from the nozzle 15 as shown in FIG. A plurality of outlets 13 formed in the water guide 13
a is discharged outside. The water discharged from the discharge port 13a is recovered in the recovery part 19c of the recovery tank 19.
In the air cleaning device 1, dust and odor components in the air are dissolved in the sprayed water, so that the air is purified. The water sprinkled in the wind tunnel 11 is guided along the inner surface of the water guide section 13 into the water stored in the collection tank section 19c, so that the water is scattered outside the collection tank section 19c or a dropping sound of water drops is generated. Can be prevented.

[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 an air purifying apparatus 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 suction port 12a for sucking outside air. In addition, a water guiding portion 13 is provided below the wind tunnel 11 so as to prevent water and liquid sprayed in the wind tunnel 11 from scattering around.
The lower end edge of the water guiding section 13 is disposed in a water storage in a collecting section 19c to be described later, and as shown in FIG.
A plurality of outlets 13a formed in a V-shape from the lower end edge are provided to discharge the air in 1.

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

In 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 pump 16 disposed outside the wind tunnel 11. The suction pipe 18 of the pump 16 is connected to the wind tunnel 11.
And extends into the water supply section 19a of the recovery tank 19 below the storage tank. As a result, the water in the water supply unit 19 a is sucked up by the pump 16 and sprayed into the wind tunnel 11 via the nozzle 15. The nozzle 15 is shaped such that water can be sprayed over the entire air passage of the wind tunnel 11.

The recovery tank 19 is provided with the above-mentioned water supply section 19a.
And a partitioning section 19b and a collecting section 19c. The lower edge of the water guide 13 is disposed in the water storage in the recovery unit 19c. Therefore, the water sprayed in the wind tunnel 11 travels along the inner surface of the water guiding section 13 and is guided into the water storage in the collecting section 19c.

In the air purifying apparatus 1, for example, when a start button (not shown) is pressed, the fan 14 and the pump 16 are driven. Thereby, the surrounding air is sucked into the wind tunnel 11, and the clean water in the water supply unit 19a is sprayed into the wind tunnel 11. Therefore, the sucked air passes through the sprayed clean water for a relatively long distance 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 the sprayed water is taken away from the sucked air to lower the temperature, so that there is also an effect that the cool air is discharged.

In this air cleaning device 1, the nozzle 1
Since the air only passes through the water sprayed from 5, the resistance to the air is small, so that the fan 14 having a small capacity, such as an axial fan, can be used at a low cost. . Further, the water sprayed in the wind tunnel 11 travels along the inner surface of the water guiding portion 13 and is guided into the water storage in the collecting portion 19c, so that the water does not scatter outside the collecting portion 19c, and the water droplets fall. There is no sound.

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

[0017]

[Effect of the Invention] As described above, the present invention sprays water or an appropriate liquid into a wind tunnel so that air passes through the wind tunnel. A water guiding section is provided, and the water guiding section is provided with a discharge port for discharging air above a lower end thereof.

Therefore, according to the present invention, it is possible to purify a wide range of air with a simple structure, to prevent scattering of water and a dropping sound of water droplets, The outlet for discharging air is provided above the lower end of the water supply, so even if the lower end of the water guide section is in water or liquid, for example, the power of the fan for discharging air can be small, and power can be saved. There are effects such as being able to.
