[0014] Then, the sterilizing means stops the supply of both the contaminated air and water to the air purification chamber 8 at a fixed cycle, supplies the electrolytic solution, and supplies the electrolytic solution into the air purification chamber 8 after the sterilization is completed. This is an electrolytic sterilizer 2 for supplying a certain amount of water for washing the liquid.

Further, a drive fan 10 is provided which also serves as a drying means for drying the inside of the air purification chamber 8 after sterilization and washing with the electrolytic solution.

The perforated plate 1 is disposed substantially in the middle of the air purification chamber 8, and a demister 7 is disposed above the perforated plate 1, and a driving fan 10 is provided between the demister 7 and the exhaust port 9.
Is arranged.

The perforated plate 1 has a large number of small holes formed in the plate thickness direction. The perforated plate 1 is provided with a water supply pipe 17 serving as washing water supply means for supplying washing water onto the perforated plate 1. The cleaning water is supplied to the cleaning water layer 6 to form a cleaning water layer 6, and the outdoor contaminating air and the indoor contaminating air are passed through the cleaning water layer 6. At this time, the outdoor contaminating air and the indoor contaminating air are brought into contact with the cleaning water. Thus, dust, odor components, harmful gas components and the like in the contaminated air are removed to form purified air.

The demister 7 is formed by stacking mesh plates.
It is arranged above the perforated plate 1. The purified air that has passed through the perforated plate 1 passes through the demister 7 to remove splashes of water contained in the purified air.

An intake port 3 is arranged below the perforated plate 1 and beside the air purification chamber 8, and contaminated air is taken in from the intake port 3.

m and the Cl ^- concentration is 10 ppm. The Cl ^-
The a bactericidal action in the electrolytic sterilizer 2 ClO ^- is to electrolysis.

As shown in FIG. 2, first, washing water H ₂ O
To produce H ⁺ and OH ⁻ . Then, Cl contained in the wash water ^- but generates an, this time in H ₂ O and electrons e ^{- -} and OH ^- from the ClO is produced. The electron e ^- is moved in the positive electrode, the electrons e ^- and H ⁺ from H ₂
Is generated. Then, ClO ^- performs a disinfection of the air cleaning chamber 8 by using the electrolyte containing.

Hereinafter, the operation of the air purifying apparatus will be described with reference to FIG. When the drive fan 10 is operated, the pump 20 is operated in conjunction with the drive fan 10 to continuously supply the washing water onto the perforated plate 1 from the water pumping pipe 17 to form the washing water layer 6 on the perforated plate 1. .

The washing water dropped from the washing water layer 6 after passing through the perforated plate 1 is stored in the water storage section 4. As described above, the washing water is stored in the water storage unit 4, the water pump 20, the water pump 1
7. Circulate on the perforated plate 1 and the water storage unit 4 in this order.

Now, the contaminated air taken in from the air inlet 3 passes through the washing water layer 6 on the perforated plate 1 and comes into contact with the washing water, whereby the dust, odor components,
Purified air is obtained by removing harmful gas components and the like.

When the contaminated air passes through the washing water layer 6, the purified air is cooled by an amount corresponding to the latent heat of evaporation of the washing water. At this time, the purified air is humidified, It will contain water droplets.

Thereafter, the purified air is passed through the demister 7 to remove water droplets contained in the purified air. Thereafter, the purified air is discharged from the exhaust port 9 and supplied to a predetermined place.

By the way, at 4:00 am according to a signal from the timer, the air purification device closes the solenoid valve 18a and stops the water supply from the water supply pipe 5. At this time, the driving fan 10 also stops, and the water pump 20 also stops. Further, the electromagnetic valve 18b is opened, and the contaminated washing water is drained from the drain pipe 19. When the drainage is completed, the solenoid valve 18 is turned off.
b is closed, and thereafter tap water is supplied to a certain water level.

Next, the electrolytic sterilizer 2 is operated to perform cleaning.
The concentration of HClO in water, ie ClO ^-With increased concentration of
A solution is generated, and the electrolyte is supplied into the air purification chamber 8.
You. That is, the pump 20 is operated, and the
, The electrolytic solution is continuously supplied to the water storage section 4,
Circulation in the order of pump 20, pumping pipe 17, on perforated plate 1, and water storage section 4.
I do. This operation is performed for about 30 minutes. During this time, the perforated plate 1,
The inner wall surface of the air purification chamber 8 and the inside of the water pipe 17 are sterilized.
You.

Thus, the inside of the air purification chamber 8 can be evenly sterilized by the electrolytic solution stored in the water storage section 4. Moreover, by performing this sterilization at a constant cycle, the inside of the air purification chamber 8 can be uniformly and reliably sterilized.

After the sterilization is completed, the water pump 20 is stopped, the solenoid valve 18b is opened, and the electrolyte after the sterilization is drained from the drain pipe 1.
Drained from 9. Next, the solenoid valve 18b is closed, and tap water is again supplied to a certain water level. Then, the pump 20 is operated to continuously supply the tap water onto the perforated plate 1, and circulates in the order of the water storage unit 4, the water pump 20, the water pump 17, the perforated plate 1, and the water storage unit 4. Then, the residual chlorine component in the perforated plate 1, the inner wall surface of the air purification chamber 8, and the inside of the pumping pipe 17 is washed. After washing for about 3 minutes, the solenoid valve 18b is opened again, and the washed water is drained from the drain pipe 19.

Electrolytic sterilizer 2 for performing a series of operations described above
Thereby, the inside of the air purification chamber 8 can be evenly sterilized, and the obtained purified air has no odor and can provide an air purification device that does not cause health damage to the human body.

Next, when air purification is performed continuously after the drying operation, the solenoid valve 18a is opened again to supply tap water. When the water level reaches an optimum level, the water supply is stopped by the float valve 11. Thereafter, when the drive fan 10 is operated, the water pump 20 is operated in conjunction therewith to start air purification.

If the air purification is not performed after the drying operation, the water is not supplied, the driving fan 10 is operated for a certain time, and the inside of the air purification chamber 8 is dried. Stop operation of. in this way,
Drying the inside of the air purification chamber 8 can suppress the growth of bacteria, and is particularly effective when the air purification device is not used for a long time.
