The ceramic balls 28 in the lower and middle layers are added with minerals by immersing them in mineral water in advance. Here, the plant P which rooted by making the ceramic ball 28 culture | cultivate only in each accommodating port 20 is accommodated.

On the other hand, the water supply tank 15 has a slightly larger cylindrical shape than the receiving portion 14, the upper end of the flange of the receiving portion 14 by the connecting portion (29, 29 ...) arranged at predetermined intervals along the circumferential edge ( By being connected to the lower surface of 16, it is supported below the accommodating part 14 in the state which opened the outer side of the ventilation board 17. FIG. Therefore, the receiving portion 14 is formed with an internal vent 30 through which air, which has entered from the upper surface opening, exits radially outward through the vent holes in the front, rear, left, and right vent plates 17.

Moreover, the cover part 31 which closes between the connection parts 29 and 29 and reaches the upper side of the water supply tank 15 is provided in the back side of the water supply tank 15, and the opening provided in the side surface of the cover part 31 is provided. The water supply path to the water supply tank 15 is formed by the notch 33 provided in the upper part of the water supply tank 15 in the cover part 31. As shown in FIG. On the back side of the lower case 3, a water supply port 34 corresponding to the opening 32 is provided on the outside of the cover portion 31 so as to be opened and closed by the lid 35.

In the air cleaner 1 comprised as mentioned above, the water supply tank 34 is supplied from the water supply port 34 in the state which accommodated the ceramic ball 28 and the plant P in each accommodating port 20, and inserted into each holding cylinder 18. As shown in FIG. A predetermined amount of water is supplied into (15). As a result, the lower portion of each accommodation port 20 is submerged in the water in the water supply tank 15, and the porous ceramic balls 28 absorb the water to supply water to the plant P. FIG. In addition, the decay of water is prevented by the mineral added to the ceramic balls 28 at the bottom, and the nutrients necessary for the plant P are also supplied. Thus, the plant P is grown at each receiving port 20.

In addition, since the lower portion of the water supply pipe 24 is submerged in water, the nonwoven fabric 25 sucks water, and water is also supplied to the ceramic balls 28 around the holding cylinder 18.

If power is supplied to the fan 9 by operating the operation switch 12 in this state, and the fan 9 is driven, as shown by the arrow in FIG. 2, the inlet 6 from the upper surface into the upper cover 5 is shown. Outside air is introduced. At this time, dust in the air is first removed by the dustproof filter of the inlet 6.

Next, the air introduced into the upper cover 5 passes through the inside of the receiving portion 14 by the internal aeration passage 30 as shown in FIG. ) Radially outward. At this time, air passes between and inside the plurality of ceramic balls 28 in the accommodating portion 14, so that harmful substances such as formaldehyde, toluene and xylene, odorous components such as acetaldehyde and ammonia, and various germs are absorbed. .

Moreover, since the through holes 19 and 21 are formed in the holding cylinder 18 and the accommodating port 20, air also passes between the ceramic balls 28 in the accommodating port 20. As shown in FIG. Since useful microorganisms, such as the mycorrhizal fungi, are generated in the roots and surroundings of plants, harmful substances are more effectively absorbed and decomposed by these useful microorganisms. In particular, since these useful microorganisms can also flow out of the holding cylinder 18 via the through holes 19 and 21, they are propagated to the ceramic balls 28 in the receiving portion 14. Therefore, the absorption and decomposition action of harmful substances and the like in the accommodating portion 14 are suitably obtained.

Air passing through the receiving portion 14 in this way reaches the inlet 11 through the side surface of the water supply tank 15, and is discharged from the exhaust port 4 through the duct 10 from the fan 9. Here again, the deodorization filter purifies and deodorizes the air.

Therefore, when the air cleaner 1 is installed and operated indoors, the indoor air can be effectively purified and deodorized to maintain a comfortable indoor space. In addition, since the water level in the water supply tank 15 can be confirmed by the float pipe 26, what is necessary is just to supply water from the water supply port 34 when water decreases. Moreover, when the top cover 5 is removed, the plant growth unit 7 is exposed so that the accommodation port 20 can be easily removed from the holding container 18, so that the plant can be easily cleaned or replaced.

As described above, according to the air cleaner 1 of the above aspect, the air passage 30 through which the air can pass through is formed in the receiving portion 14 of the plant growth unit 7 so that the plant growth unit 7 is inlet ( 6) and a plurality of holding cylinders 18 which communicate with the water supply tank 15 at the bottom of the receiving portion 14, are arranged on the bottom of the air passage between the exhaust port 4, and the holding cylinder ( 18, the receiving port 20 of the bottomed container containing the ceramic balls 28 and the plant P is kept detachably inserted while the lower end of the receiving port 20 protrudes into the water supply tank 15. At the same time, through-holes 19 and 21 are formed in the holding cylinder 18 and the receiving port 20 to communicate the inside and the outside, and the ceramic balls 28 are also filled around the holding cylinder 18 to form a cylindrical shape. In addition to the dustproof filter and the deodorizing filter, the ceramic balls 28 and the plant P can be used to effectively absorb and decompose harmful substances in the air. Excellent purification can be performed, this deodorizing function is obtained. In particular, the introduced air has a structure that reliably passes through the accommodation portion 14 and the accommodation port 20 in the plant growth unit 7, thereby sufficiently exhibiting the absorption and decomposition of harmful substances by useful microorganisms generated. .

In particular, the main body case 2 is a bottomed cylindrical case 3 having a bottom having a fan 9 and having an exhaust port 4 provided on the side thereof, and an upper surface of the lower case 3. It has the transparent cylindrical upper cover 5 provided with the inlet port 6, and hangs the flange 16 of the accommodating part 14 of the plant growth unit 7 to the upper opening of the lower case 3. The lower end opening of the upper cover 5 is deposited on the flange 16, and the internal aeration path 30 is an air vent provided from the upper opening of the accommodation portion 14 on the side wall of the accommodation portion 14. It is formed so as to radially escape out of the accommodating portion 14 from the hole, and the air introduced into the main body case 2 passes through the entire accommodating portion 14, thereby causing harmful substances caused by the ceramic balls 28 or useful microorganisms. Absorption and decomposing action of the back can be more suitably exhibited.

And the water supply pipe 24 which supplies the water in the water supply tank 15 to the ceramic balls 28 around the holding cylinder 18 in the accommodating part 14 is provided, and is filled around the holding cylinder 18. Moisture is also supplied to the ceramic balls 28 to promote the deodorizing effect. In addition, since the same growth environment as that in the receiving port 20 is formed, the root of the plant is easily extended to the outside of the holding container 18, which leads to more effective breeding of useful microorganisms.
