The air cleaner of the present invention includes a purification filter 40 for purifying the air cleaning liquid 5 separated and collected by the liquid separation filter 8, and a collection tray 41 for recovering the air cleaning liquid 5 purified by the purification filter 40. an observation window 42 formed on the surface of the main body 1 to observe the contamination state of the air cleaning liquid 5 inside the main body 1 collected by the collection tray 41; and a lighting device 50 for illuminating the air cleaning liquid 5 that has passed through the purification filter 8. and is provided.

The collection tray 41 is a rectangular transparent body, and a recess 41a is formed in the center of the rear surface to accommodate the illumination device 50. 15 and a support piece 45 protruding from the front wall 10.

The observation window 42 is made by bonding a transparent plastic plate to a square hole provided in the front wall 10 above the support piece 45, and waterproofing the bonded portion with adhesive or the like.

The purification filter 40 is provided below the liquid separation filter 8 and has a function of purifying the air cleaning liquid 5 collected by the liquid separation filter 8 and dripped onto the collection tray 41. The purification filter 40 is a porous filter composed of an activated carbon layer, a layer formed by melting antibacterial metal ions, a layer containing an antibacterial agent or a bactericidal agent, etc., and the center part thereof is a slightly thin flat plate. It is formed in a shape and slopes downward from the outer periphery to the center. The purification filter 40 is supported by protruding pieces 47 provided at the upper four corners of the collection tray 41.

Then, the purification filter 40 and the collection tray 4
1 is formed to be detachable from the main body 1. That is, when the lid 14, the upper plate 25, and the collision plates 27, 28 are removed upwardly, the purification filter 40 and the recovery tray 41 can be removed laterally and replaced.

The lighting device 50 is a general miniature light bulb,

In the figure, 48 is a replacement door for the tank 37, and 49 is a power switch that also serves as a power/weak switch.

In the above configuration, the user can switch the power switch 49
When turned on, the fan motor 34 starts rotating,
The blower device 4 is driven, and an air flow from the intake port 2 to the exhaust port 3 is formed. At the same time, the ultrasonic oscillation circuit 36 starts oscillating, the piezoelectric element 35 is driven, and the air cleaning liquid 5 is atomized into droplets.

The air sucked in from the intake port 2 passes through the passage 19 from the air intake chamber 21 and is guided to the atomization section 31 of the mixing chamber 7 via the prevention tube 24 opened above the water surface. Here, the air cleaning liquid 5 that has been atomized into droplets by the atomization device 6 is mixed with the air, and then collides with the collision plates 27 and 28 in the mixing section 32, so that the air and the droplets can be further improved. mixed. At this time, dust and odor components in the air adhere to or dissolve into the liquid droplets and are removed, reaching the liquid separation filter 8.

The mixture of droplets and cleaned air to which contaminants such as dust and odor components have adhered or dissolved is removed here, and only the clean air is sent from the exhaust port 3 via the blower 4. It is discharged indoors.

The operations described above remove pollutants from indoor air.

On the other hand, the air cleaning liquid 5 separated and collected by the liquid separation filter 8 is dropped onto the purification filter 40, purified by the purification filter 40, and then placed in the collection tray 4.
It reaches 1. Then, after temporarily staying in the collection tray 41, it returns to the cleaning liquid reservoir 26.

When this circulation is repeated, the purification filter 40 gradually deteriorates, and as a result, the air cleaning liquid 5 inside the main body becomes less transparent and turns brown. In this case, the air cleaning ability decreases, and it becomes necessary to replace the purification filter 40.

At this time, since the lighting device 50 is provided inside the main body 1 and illuminates the air cleaning liquid 5 in the collection tray 41, the state of the air cleaning liquid 5 in the collection tray 41 is as follows.
It can be clearly observed through the observation window 42.

That is, when the capacity of the purification filter 40 decreases and the degree of contamination of the air cleaning liquid 5 exceeds a certain level,
Since the light from the illumination device 50 is no longer observed through the observation window 42, contamination of the air cleaning liquid 5 can be avoided by simply looking through the interior illuminated by the illumination device 50 through the observation window 42, without having to take the trouble to open the lid 14 and disassemble the interior. can be easily discovered, and the time to replace the purification filter 40 can be known.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, the illumination device 50 may be installed at another location (for example, point A in the figure), and the collection tray 41 may not be provided independently, but may also be the same as the cleaning liquid reservoir 26.

<Effects of the invention> As is clear from the above explanation, according to the present invention, the main body includes an atomization device that atomizes air cleaning liquid into droplets, and a droplet atomized by the atomization device and intake air. The liquid separation filter has a mixing chamber that mixes the air inhaled through the mouth and allows the contaminants contained in the air to adhere and dissolve into the droplets, and the liquid separation filter removes contaminants such as dust and odor components. Droplets are removed from the mixture of adhered or dissolved droplets and cleaned clean air, and only the clean air can be discharged into the room from the exhaust port, making the overall structure simple and compact, and improving the living space. The air purifying liquid separated and recovered by the liquid separation filter is illuminated by a lighting device and can be clearly observed through the observation window, making it easy to know the state of contamination and when to replace the purifying filter. It has an excellent effect.
