Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an easy-to-maintain air cleaner that not only removes indoor dust but also removes especially cigarette odor and body odor.

Conventional technology Nowadays, comfort and cleanliness are required in living and office environments, and the need for air purification is increasing, and sales of air purification equipment products are showing significant growth. Among these, the removal of cigarette smoke and odor was a major need, and the greatest challenge was to find a perfect method for removing it. Therefore, product development is actively underway to solve these needs.

However, the current mainstream of air purification is
The combination of electrostatic precipitator and activated carbon filter, as exemplified by Publication No. 5, has not been able to completely remove cigarette smoke and odor for a long time. Therefore, attention has been focused on water, which has a high dissolution characteristic for malodorous components, and water, or aqua-type deodorization methods, are attracting attention.

Wet-type G2 odor devices using sprays such as scrubbers have traditionally been used for industrial purposes, but because of the large size of the devices, they have been avoided for commercial or home use. For commercial use, wet filter single-type systems and water eddy current systems in which gas is passed through the water have been devised, but they are still too large for commercial or household use. For home use, the product is an Aqua-type air purifier that aims to be more compact and uses ultrasonic vibrations to atomize the water in the aquarium, absorb dust and odors, and then reconstitute the water with a drainer shielding plate and circulate it through the ultrasonic tank. has been made into However, with this method, the circulating water becomes extremely dirty, and not only does the water become contaminated in a short period of time, but also dirt such as resin sticks to various parts, and furthermore, mold and mildew can occur due to the high humidity. It was considered that it was not good for environmental health. Therefore, it is necessary to replace each member in a short period of time, which not only requires time and effort for maintenance, but also poses a problem of high running costs.

In order to solve the above problems,
In this publication, a method is devised in which an ozone generator is installed in the air discharge section of the pump, and the bubbles generated in the bath contain ozone, which has a high sterilizing and deodorizing ability, to sterilize and deodorize the bathtub.

Problems to be Solved by the Invention However, in the above-mentioned Japanese Patent Application Laid-Open No. 56-106651, ozone is used to sterilize and deodorize circulating water;
Since the method of injecting ozone into water requires large pumping capacity, it is difficult to treat large volumes of air with this method.

In view of the above-mentioned problems, the present invention atomizes the water in the aquarium using ultrasonic vibrations to efficiently adsorb dust and bad odors, and then returns the water to water using a drainage shielding plate, etc., and removes the dust and bad odors by draining water. By applying ozone gas, the generation of dirt and mold on each part is minimized, simplifying maintenance and reducing running costs.

Means for Solving the Problems In order to solve the above-mentioned source M, the air purifier of the present invention includes a sprayer that converts water in an aquarium into atomized water droplets, and an ozone generator that blows ozone gas into the atomized water droplets. A gas mixing zone, a draining zone, and an intake/exhaust fan are provided between the intake port and the exhaust port, and in the gas mixing zone, a mixed gas of the atomized water droplets, outside air from the intake port, and ozone gas is generated. After that, the gas is exhausted by an intake/exhaust fan from an exhaust port through a draining zone. In the draining zone, a draining plate converts the mixed gas into a large aqueous solution, and the aqueous solution is drained from a drain port.

Effect of the present invention With the above-described configuration, the atomizer generates atomized water droplets in the gas mixing zone and significantly increases the surface area of the water, thereby efficiently adsorbing dust contained in the outside air and the depths of cigarettes, etc. Ozone gas is also adsorbed at the same time.

Then, in the next draining zone, water droplets adsorbing particulate dust and cigarette smoke collide with the draining plate, converting into large aqueous solutions, falling under their own weight, and being drained outside through the drain port. At this time, most of the dust, cigarette odor, etc. is drained while being adsorbed by the aqueous solution, and some of it is decomposed by ozone. In addition, the remaining ozone sterilizes and purifies the surfaces of each component, thereby preventing the water from rotting and molding, thereby suppressing dirt on each component and requiring almost no maintenance.

EXAMPLE Hereinafter, an air cleaner according to an example of the present invention will be described with reference to the drawings.

1 is an air cleaner having an intake port 2 and an exhaust port 3. A space between the intake port 2 and the exhaust port 3 is composed of a gas mixing zone 4, a draining zone 5, an intake/exhaust fan 6, and an ozone decomposition filter 7. In the gas mixing zone 4, an ultrasonic oscillator 8
The atomized water droplets generated by the atomizer 9 with the ozone generator 10, the ozone gas formed by the ozone generator 10, and the outside air sucked through the inlet 2 are mixed to form a mixed gas. The draining zone 5 is composed of a plurality of draining plates 12 having an intricate structure that slopes downward toward the drain port 11 side.

The sprayer 9 includes a water tank 13, a piezoelectric element 14, and an ultrasonic generator 8.
The water filled in the water tank 13 can be converted into atomized water droplets using the power of ultrasonic waves and blown up into the gas mixing zone 4. Water is poured into the water tank 13 by receiving an electric signal from a water level sensor 15 and opening and closing a water injection valve 17 of a water pipe 16 to set the water level to an appropriate level.

The ozone generator 10 includes a high voltage power supply 18 and an ozonizer 19.
and a fan 20 to blow ozone gas into the gas mixing zone 4.

The draining zone 5 is composed of a plurality of draining plates 12 having an intricate structure that slope downward toward the drain port 11 side. The structure is such that the rice collides with the draining plate 12, condenses into large aqueous solution particles, and falls along the draining plate 12 into the drainage tank 21.

The drain tank 21 is connected to the drain valve 2 by a float switch 23.
The water level in the drainage tank 21 is controlled by opening and closing 4. That is, when drainage water accumulates, the float switch 23 operates to open the drainage valve 24 to complete the drainage at once, and when the drainage is completed, the drainage valve 24 is closed.

In addition, 25 is a control box of the air cleaner 1.

The operation of the air cleaner 1 configured as above will be described below with reference to the drawings.

First, by operating the intake/exhaust fan 6, outside air containing dust and cigarette odor is introduced from the intake port 2 into the gas mixing zone 4 in the air cleaner 1. In the gas mixing zone 4, there are atomized water droplets obtained by converting water in a water tank 13 by a sprayer 9 using ultrasonic waves, and ozone gas produced by an ozone generator.

Dust, especially cigarette smoke and odor components, and ozone gas have the property of being relatively easily adsorbed to water, and furthermore, as the surface area increases approximately 7000 times through atomization, they can easily be absorbed into atomized water droplets. is adsorbed to create a gas mixture.

This gas mixture is pulled by the intake/exhaust fan 6 and then introduced into the draining zone 5. In the draining zone 5, since the draining plate 12 has a complicated structure,
The mixed gas does not flow smoothly and collides with the drain plate 12, causing the mist water droplets to condense and turn into large aqueous solution.

The large aqueous solution contains ozone, dust adsorbed from the outside air, and the smell of cigarettes. This aqueous solution will flow into the drainage tank 21 along the plurality of draining plates 12. The aqueous solution that has flowed into the drain tank 21 remains there until the float switch 23 of the drain tank 21 is activated. When the aqueous solution accumulates to the position of the float switch 23, the float switch 23 is activated and the drain valve 24 is opened to drain the water all at once. The purpose of the layer in which wastewater is temporarily stored is to prevent dust extracted from the outside air from accumulating at the bottom of the drainage tank 21 and clogging the drain port 11. This is to wash it away regularly. Furthermore, if the drain port 11 is left open all the time, not only will dust and the like be likely to accumulate, but also there is a possibility that outside air with foul odor may flow back through the drain port 11.

The mixed gas that has not condensed in the draining zone 5 is exhausted into the room by an intake/exhaust fan 6 through an ozone decomposition filter 7 and an exhaust port 3. The ozone decomposition filter 7 is mainly composed of activated carbon and titanium oxide, and is set as a precaution to prevent unreacted ozone from being discharged into the room. Exhaust gas treated in this way has its original dust and cigarette odor completely removed with water and ozone, resulting in clean air.

Effects of the Invention As described above, the air purifier of the present invention has a sprayer that converts water in an aquarium into atomized water droplets, an ozone generator that blows ozone gas into the atomized water droplets, and an intake port and an exhaust port. A gas mixing zone, a draining zone, and an intake/exhaust fan are provided in between.
In the gas mixing zone, the above-mentioned mist water droplets, outside air from the intake port, and ozone gas are mixed into a gas mixture, which is then exhausted by an intake/exhaust fan from the exhaust port through the draining zone, and mixed in the draining zone. It converts gas into a large aqueous solution and drains the aqueous solution from the drain port, removing dust and dirt.
Not only does it completely remove the smell of cigarettes, but it also uses ozone to sterilize and clean each component, thereby minimizing maintenance.
