Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air purifier that is easy to maintain and that not only removes indoor dust but also removes 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-related equipment products are showing significant growth. Among these, the main need was to remove cigarette smoke and odor, and the greatest challenge was to find a perfect method for removing it. Furthermore, dryness during heating during winter was a major cause of loss of comfort and was a problem. 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 property for malodorous components, and water, or aqua-type deodorization methods, are attracting attention. With this deodorizing method, it is possible to add a humidifying function at the same time.

Wet-type deodorizing devices using sprays such as scrubbers have traditionally been used for industrial purposes, but they have been avoided for commercial or home use because of the large size of the devices. 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.
Not only did the water become contaminated in a short period of time, but various parts were covered with dirt and grime, and the humid conditions led to the growth of mold, which was considered bad for the environment. 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. Further, although humidification in winter is possible, the capacity is insufficient and there is a problem in that the humidity increases further in the humid summer.

Furthermore, in order to solve the above problems,
Japanese Patent No. 6651 devises a method of sterilizing and deodorizing a bathtub by installing an ozone generator in the air discharge section of the pump and causing bubbles generated in the bath to contain ozone, which has a high sterilizing and deodorizing ability.

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 a national problem to treat large volumes of air using this method. Furthermore, there is currently no concrete plan for adding a humidity control function.

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. Further, by controlling the temperature of the surface of the draining plate, dehumidification and humidification can be controlled.

Means for Solving the Problems In order to solve the above eight problems, the air purifier of the present invention includes a sprayer that converts water in an aquarium into S-shaped water droplets, and an ozone generator that blows ozone gas into the mist 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 the exhaust port through a draining zone having a draining plate. It has a humidity control function by controlling the temperature of the surface of the draining board.

Effects 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. Ozone gas is also adsorbed at the same time. Then, in the next draining zone, water droplets adsorbing fine particles of dust and cigarette smoke collide with the draining plate.
It converts into a large aqueous solution, falls under its own weight, and is drained outside through the drain. 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. Furthermore, the humidity at the exhaust port can be adjusted by controlling the temperature using a heater and a refrigerant pipe on the draining plate.

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. Further, a heater 13 and a refrigerant pipe 14 are integrally formed on this draining plate 12, so that the surface temperature can be freely controlled.

The sprayer 9 includes a water tank 15, a piezoelectric element 16, and an ultrasonic generator 8.
The water filled in the water tank 15 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 15 by receiving an electric signal from a water level sensor 17 and opening and closing a water injection valve 19 of a water pipe 18 to set the water level to an appropriate level.

The ozone generator 10 includes a high voltage power supply 20 and an ozonizer 21.
and a fan 22 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 water solution collides with the draining plate 12, condenses into large aqueous solution particles, and even if it flows down the draining plate 12, it always falls into the drainage tank 23.

The drain tank 23 is connected to the drain valve 2 by a float switch 25.
The water level in the drainage tank 23 is controlled by opening and closing 6. That is, when drainage water accumulates, the float switch 25 operates to open the drainage valve 26 to complete the drainage at once, and when the drainage is completed, the drainage valve 26 closes.

Note that 27 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 into the gas mixing zone 4 in the air cleaner 1 through the intake port 2. In the gas mixing zone 4, there are atomized water droplets obtained by converting water in a water tank 15 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 23 along the plurality of draining plates 12. The aqueous solution that has flowed into the drain tank 23 remains there until the float switch 25 of the drain tank 23 is activated. When the aqueous solution accumulates up to the position of the float switch 25, the float switch 25 is activated and the drain valve 26 is opened to drain the water all at once. The reason for temporarily storing the waste water is to prevent dust extracted from the outside air from accumulating at the bottom of the drain tank 23 and clogging the drain port 11. This is to wash it off regularly. Furthermore, if the drain port 11 is always left open, not only is it easy for dust etc. to accumulate, but also there is a possibility that outside air with a bad odor may flow back through the drain port 11.

In addition, the temperature of the draining plate 12 can be controlled by a heater 13 and a refrigerant pipe 14, and when you want to humidify, heating the draining plate 12 with the heater 13 increases the amount of natural evaporation, and when you want to dehumidify, you can pass the refrigerant through the draining plate. Cooling makes aggregation more active.

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 exhaust gas 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 includes a @ fogger 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. A gas mixing zone, a draining zone, and an intake/exhaust fan are provided between the exhaust port and the atomized water droplets, outside air from the intake port, and ozone gas are made into a mixed gas in the gas mixing zone, and then drained. The system uses an intake/exhaust fan to exhaust air from the exhaust port through a draining zone with a plate.The draining plate in the draining zone converts the mixed gas into a large aqueous solution, and the aqueous solution is drained from the draining port, and the surface of the draining plate is It has a humidity control function by controlling the temperature, and not only does it completely remove dust and cigarette odors, but it also uses ozone to sterilize and clean each component, reducing maintenance as much as possible. This allows humidity control.
