Abstract

PROBLEM TO BE SOLVED: To provide an air cleaner capable of removing fine particles, bad odors, and disease germs from object air and discharges an extremely small amount of wastes.SOLUTION: A mechanism for removing fine particles has a built-in prefilter (1), electrostatic type filter (2), ionizer (3), film dust collection electrode (4), and electret filter (7). These apparatuses (1), (2), (3), (4) are reusable by cleaning. A mechanism for removing bad odors has a built-in antibacterial deodorant filter. A mechanism for removing disease germs has a built-in germicidal lamp (5). These built-in apparatuses contribute to both removing harmful substances from object air and reducing wastes.SELECTED DRAWING: Figure 1

Description

The invention of the present application relates to an air cleaner having a function of collecting and removing particulates represented by PM2.5 in the air. It also sterilizes bacteria in the air. At the same time, it removes odors in the air.

As represented by PM2.5, at present, in the field of air purifiers, it is an important theme to remove fine particles such as soot, dust, bacteria, pollen and ultra fine particles floating in the air. In order to remove these fine particles, a HEPA filter (High Efficiency Particulate Air Filter) is often used, but such a filter is mostly made of a fine fibrous material in a mesh shape. When used, target air is sent by a fan and applied to the surface of the filter to collect and remove particulates.

unknown

None

The absolute amount of fine particles and ultrafine particles in the air varies depending on the number of people in the room. When the HEPA filter as described above is used, it exhibits sufficient performance for home use, but when used in a large number of environments such as hospitals and elderly facilities for business use, the HEPA filter is used for a short time. Saturated at this point, it is not possible to demonstrate sufficient performance.

In addition, when used for business purposes, there are many health-impaired people in hospitals, elderly facilities, etc., and thus bacterial suppression is necessary, but general air purifiers do not have sufficient bacterial suppression functions.

The air cleaner of the present invention includes a pre-filter that collects dust having a large particle size, an electrostatic filter that collects dust having a positive potential, an ionizer that charges the dust with a positive potential, and a positive potential. A negatively charged film dust collecting electrode to collect the dust, a germicidal lamp that sterilizes bacteria attached to the film dust collecting electrode and electret filter, and a fiber containing a deodorant and an antibacterial agent It consists of an antibacterial deodorizing filter, an electret filter that collects dust that does not carry a positive potential, and a crossflow fan with a fan attached to the rotor.

By configuring as described above, the present invention can completely remove pollen, asbestos, glass fiber or the like of about 10 μm from fine bacteria of about 0.01 μm (micrometer 1 μm = 0.001 mm). Is to provide.

FIG. 1 is a block diagram of the present invention, wherein 1 is a pre-filter, 2 is an electrostatic filter, 3 is an ionizer, 4 is a wound film dust collecting electrode, 5 is a germicidal lamp, and 6 is an antibacterial deodorant. A filter, 7 is an electret filter, and 8 is a cross flow fan.

Examples will be described in detail.

FIG. 1 is a block diagram of the present invention, wherein 1 is a pre-filter, 2 is an electrostatic filter, 3 is an ionizer, 4 is a wound film dust collecting electrode, 5 is a germicidal lamp, and 6 is an antibacterial deodorant. A filter, 7 is an electret filter, and 8 is a cross flow fan.

Next, the operation will be described in detail. When the power of the air cleaner configured as shown in FIG. 1 is turned on, the cross flow fan 8 rotates and dirty air is sucked from the prefilter 1 side. A large dust particle in the sucked dirty air is captured by the electrostatic filter 2 charged to a negative potential. The dust that has passed through the electrostatic filter 2 has a positive potential and is attracted to the film dust collecting electrode 4 by an ionizer 3 for charging the dust with a positive potential. In addition, dust that is partially repelled by the ionizer 3 and has a positive potential is absorbed by the electrostatic filter 2.

Dust that has not passed through the film dust collecting electrode 4 and that has not been captured by the film dust collecting electrode 4 or fine particles that cannot be captured by the film dust collecting electrode 4, such as viruses or minerals, is captured by the electret filter 7 having a negative potential. To do. Further, the bacteria attached to the electret filter 7 are sterilized by the germicidal lamp 5.

Bacteria or odors that have not been sterilized or deodorized even by the germicidal lamp 5 are treated by an antibacterial deodorizing filter 6 in which fibers containing an antibacterial agent are stacked on the deodorizing filter.

Furthermore, the rotor and fan of the cross flow fan 8 are made of synthetic resin and molded by containing an antibacterial agent therein, and bacteria attached to the rotor and the fan are sterilized.

With the rapid economic development of Southeast Asian countries in recent years, air pollution is spreading at an unimaginable speed. Originally, polluted air is purified by forest trees, seawater, and sunlight, but it is difficult to purify polluted air by such natural power alone. However, a device that purifies all the air on the earth is not possible. Therefore, it is thought that it is possible to protect against air pollutants, pathogens, and viruses by purifying only the room where human beings live for a long time.
