[Industrial applications]

 The present invention relates to an air purifying device that is inexpensive and capable of achieving high performance, and particularly relates to an air purifying device that is suitable for application to a domestic air purifying device in consideration of portability.

[0002]

[Prior art]

 A conventional household air purifier uses activated carbon or fibers such as polypropylene as a filter, and forcibly sucks air through this filter to remove dust and odor contained in the air. There is a filter type cleaning device. In addition to this, there is also an ion type cleaning device in which dust and odor components in the air are charged to, for example, the + side, which is attracted to the-side electrode and collected with a paper towel.

[0003]

[Problems to be solved by the device]

 In the filter type cleaning device, the filter is clogged relatively quickly, so the filter must be replaced frequently, which is not only troublesome but also the filter cost is high. In addition, since the filter is filled with activated carbon and fibers with almost no gaps, the pressure loss becomes large, and the fan that sucks in air must also have a large capacity, which is also expensive.

In the ion type cleaning device, when the air flow speed is high, dust and the like charged on the + side are not attracted to the − side and are discharged to the outside together with the air. Therefore, the air is forcibly forced. It was difficult to aspirate and flush. Therefore, there is a problem that only the air very close to the cleaning device is cleaned, but the air outside it cannot be cleaned.

Therefore, the present invention solves the above-mentioned problems, and proposes an air purifying device that can purify a wide range of air at a low cost.

[0006]

【Example】

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

FIG. 1 shows the configuration of a household air cleaning device 1 to which the present invention is applied. The air purifying device 1 is small and portable, and a cap-shaped straightening plate 12 is provided on the upper part of a relatively small cylindrical wind tunnel 11 to straighten air. Further, a funnel portion 13 having a lower constriction is provided below the wind tunnel 11 in order to prevent the water and the liquid scattered in the wind tunnel 11 from being scattered around. A fan 14 is installed on the upper side inside the wind tunnel 11, and by driving this fan, the air around the air purifying device 1 is sucked into the wind tunnel 11 from the suction port 12a of the flow regulating plate 12. This is discharged from the discharge port 13a of the funnel portion 13 to the outside.

A nozzle 15 is arranged at the lower side of the fan 14 in the center of the wind tunnel 11, and this is connected to a discharge pipe 17 of a pump 16 arranged outside the wind tunnel 11. The suction pipe 18 of the pump 16 extends into the water supply unit 19a of the recovery tank 19 below the wind tunnel 11. 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 has a shape capable of spraying water over the entire air passage of the wind tunnel 11.

The recovery tank 19 includes the water supply unit 19a, the partition unit 19b, and the recovery unit 19c described above. As shown in FIG. 2, the partition 19b is provided with an opening 19d from the upper end to an appropriate depth, and a filter 20 is fitted in a groove 19e around the opening. The filter 20 is for cleaning the dirty water in the recovery part 19c, and a fiber filter 22 made of an appropriate material is attached to the inside of a rectangular frame part 21. A handle 23 is provided on the upper portion of the frame portion 21 so that the filter 20 can be easily attached / detached and washed.

The water sucked up from the water supply unit 19a and scattered in the wind tunnel 11 is discharged from the discharge port 13a of the funnel unit 13 and collected in the collecting unit 19c. The exhaust port 13a is arranged above the water surface of the collecting unit 19c, and the air that has passed through the wind tunnel 11 is discharged from the exhaust port 13a to the outside without resistance.

In the air purifying apparatus 1, when the start button (not shown) is pressed, the fan 14 and the pump 16 are driven. As a result, the ambient 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 over a relatively long distance and is discharged to the outside.

At this time, dust and odor components contained in the air dissolve in water, and when the air is discharged to the outside, it becomes clean air that does not contain them. On the contrary, since the clean air discharged from the air cleaning device 1 has a proper amount of water added thereto, it can be used as a humidifier. In addition, when the outside air temperature is high, such as during summer, the heat of vaporization of the sprayed water is removed from the air and the temperature drops, which has the effect of discharging cold air.

Further, in this air purifying apparatus 1, since the air only passes through the water sprayed from the nozzles 15, the resistance applied to the air is small, so that the fan 14 also has an ability like an axial fan. It is possible to use a small and inexpensive one. The water in the recovery unit 19c of the recovery tank 19 is returned to the water supply unit 19a via the filter 20 and is circulated for use, which makes it possible to save water.

FIG. 3 shows another embodiment of the recovery tank 19. In this recovery tank 19, a holding section 31 having a U-shaped opening 30 is provided on the side of the partition section 19b on the recovery section 19c side, and a shutter 32 for opening and closing the filter 20 is attached thereto. The shutter 32 is detachable, which makes it possible to select whether or not to reuse water. For example, when the water in the collection unit 19c cannot be cleaned even if the filter 20 is used, a shutter 32 is attached to prevent the water from being circulated and the collection unit 19c collects a certain amount of water. You can discard this.

Although water is used to clean the air in the above-mentioned embodiments, it is possible to add perfume or a fragrance to this, and it is also possible to use an appropriate liquid other than water. It is possible.

[0020]

[Effect of device]

 As described above, the invention according to claim 1 is one in which water or an appropriate liquid is sprayed in a wind tunnel, and air is allowed to pass through the wind tunnel, and used water is filtered by a filter. It is designed to be cleaned. Therefore, according to the invention described in claim 1, it is possible to purify a wide range of air with a simple structure, and it is possible to save water by circulating water. is there.

Further, the invention according to claim 2 is to provide a shutter for opening and closing the filter. Therefore, according to the invention as set forth in claim 2, there is an effect that it is possible to select whether to reuse the water or to discard the water as it is depending on the condition of the recovered water.
