Description

The present invention relates to a photocatalyst-equipped air purifying computer having a kind of multifunctional function. In particular, using a computer power supply and a heat dissipation fan, the action of photocatalysts and ultraviolet rays absorbs organic matter such as dust, odors, bacteria, molds, mites, pollen, pollen, etc. into the air inside and outside the computer casing. -It is related with the computer with an air purifying function which has the function to decompose | disassemble.

A conventional computer with an air purifying function has been devised to adopt a method of inserting into a computer expansion bay. (See Patent Document 1)
Utility Model Registration No. 3097434 (Figure 5)

This is a cartridge system in which a cartridge for obtaining a photocatalytic effect is inserted into an expansion bay of a computer, and an independent computer peripheral device needs to be configured separately. Further, the cartridge is only stored in the expansion bay for the purpose of purifying the air outside the computer casing, and the photocatalytic effect cannot be exhibited in the entire computer internal space. That is, there are the following problems.

First, a cleaning function for the entire air inside the housing cannot be obtained. Since the cartridge is attached to the expansion slot, it is expected that only the slot is cleaned. From the experience of PC repair work over the past nine years, the inventor discovered that the cause of computer failure / failure was organic matter such as dust, mold, mites, and pollen accumulated inside the housing.

Unlike metal housings, the main electronic components of computers such as motherboards and memories are the most demanding parts of the cleaning, though they are difficult to clean with chemicals. When the air flowing inside the housing is purified, the organic matter is reduced, the electronic components inside the computer are purified, and the useful life is extended.

Second, it cannot be installed on current mainstream desktop computers due to space constraints. As recent computers are downsized and space-saving desktops without extended bays are common, the range of applications for computers that can be fitted with conventional cartridge-type air cleaning functions is relatively reduced.

As these improvement measures, an object of the present invention is to provide a computer that can be mounted on a general-purpose computer and has a function of purifying air inside and outside the casing.

In order to solve the above-described problems, the present invention has a filter structure filter using activated carbon added with titanium oxide and a pair of titanium oxide coatings sandwiching the filter structure filter in the vicinity of an air-cooled fan inside the computer casing. When the computer is turned on, an ultraviolet ray is irradiated from the ultraviolet ray irradiation body to the triple structure filter and sucked for air cooling. By passing air through the pair of titanium oxide coating filters when air is sucked into and exhausted from the filter structure filter in the triple structure filter, dust, odor, bacteria, mold, mite carcass and Absorbs and decomposes organic matter such as dung and pollen.

According to this, when the air sucked for air cooling is sucked into the filtration structure filter in the triple structure filter, if it passes through one of the pair of titanium oxide coating filters, it is absorbed and decomposed by the photocatalytic effect. Such an air cleaning action is obtained. Further, when the organic matter absorbed and decomposed is filtered by the filtration filter and then passes through the other of the pair of titanium oxide coating filters, an air cleaning action that is absorbed and decomposed again by the photocatalytic effect is obtained. After that, this air is released outside the computer. Furthermore, the deodorizing effect by the filtration structure filter using activated carbon is also acquired.

In this case, by providing the triple structure filter in the vicinity of both the intake and exhaust fans for heat dissipation, the air cleaning action can be obtained twice. In addition, these triple structure filters are installed perpendicular to the air flow, so that the air sucked for air cooling will efficiently contact and pass through the area of the triple structure filter, Effective absorption and decomposition effects can be obtained.

According to the present invention, by combining a computer heat dissipation fan and photocatalytic technology and incorporating an air purifier in the computer, the photocatalytic effect of ultraviolet rays and titanium oxide can be obtained, and harmful organic substances and allergens can be removed. And the deodorizing effect by activated carbon is also acquired. And since it operates using the internal power supply of a computer, the energy saving effect is also acquired. A more compact design is possible.

FIG. 1 shows a local structure of a triple structure filter used in the present invention. In the vicinity of the intake fan 1, there is a triple structure filter comprising a titanium oxide coating filter 2a, 2b provided at a certain interval, and a filtration structure filter 3 using activated carbon added with titanium oxide provided therebetween. , Installed in the irradiation range of ultraviolet black light 4. When the cooling air is sucked from the intake fan 1 while the ultraviolet ray is irradiated from the ultraviolet black light 4, when the air passes through the titanium oxide coating filter 2a, dust, odor, bacteria and mold in the air -Absorbs and decomposes mite carcass and organic matter such as dung and pollen (first stage air cleaning effect). The air that has passed through the titanium oxide coating filter 2a is further debrominated by passing through the filtration structure filter 3 using activated carbon added with titanium oxide. Then, when passing through the titanium oxide coating filter 2b, organic substances such as dust, odor, bacteria, mold, mite carcass, dung and pollen are absorbed and decomposed (second stage air purification effect).

FIG. 2 is a side view of a computer equipped with this triple structure filter. In this computer, an intake fan 1 and an exhaust fan 5 are provided at both front and rear ends of the computer housing 6, and further, triple-structure filters are respectively provided inside these. A motherboard 7 is installed below the computer housing 6, and when the main switch 8 on the front is turned on, the CPU 9 is activated. Further, a CD-ROM 10 is installed on the front side of the computer housing 6, and an FD 11 is installed just below the CD-ROM 10. A PC power source 12 is installed on the back side, and an ultraviolet black light power unit 13 and an ultraviolet black light 4 are installed in the center. In the vicinity of the intake fan 1, a photocatalytic filter 2a coated with titanium oxide, a photocatalytic filter 3 with activated carbon filtration structure, and a photocatalytic filter 2b coated with titanium oxide are installed. Therefore, the photocatalytic effect is exhibited when the sucked air passes through the filter in the state where the ultraviolet ray black light 4 is irradiated during the computer operation, and the first air cleaning is performed.

In the vicinity of the exhaust fan 5, a triple-structured filter comprising a photocatalytic filter 2 a ′ coated with titanium oxide, a photocatalytic filter 3 ′ with activated carbon filtration structure, and a photocatalytic filter 2 b ′ coated with titanium oxide is installed. When the air purified in the vicinity of the intake fan 1 is sent out toward the exhaust fan 5, the photocatalytic effect is obtained by passing again through the triple-structure photocatalytic filter in the state irradiated with ultraviolet rays from the ultraviolet black light 4. Is exhibited and the second air cleaning is performed. Then, the air purified twice is discharged from the exhaust fan 5 to the outside of the computer.

FIG. 3 is a top view of the computer. The air sucked from the intake fan 1 and discharged from the exhaust fan 5 is purified twice when passing through the two triple structure filters. At this time, since the triple structure filters are respectively installed perpendicular to the air flow, they pass efficiently in contact with the area of the filter surface, and an effective absorption / decomposition effect is obtained. .

Using this machine shown in FIGS. 2 and 3, air containing cigarette smoke was sucked and exhausted, and the residual amounts of ammonia, acetaldehyde and acetic acid in the exhaust were measured. The measurement method was in accordance with the Japan Electrical Manufacturers' Association standard JEM1467 household air purifier 7.10 deodorization performance test. As a result, the results shown in Table 1 and FIG. 4 were obtained. As shown in Table 1 and FIG. 4, by operating this machine, it can be seen that the reduction of each component in the air is maintained over time after the first irradiation of ultraviolet rays.

After a few days, air containing cigarette smoke was sucked and exhausted, and the residual amounts of ammonia, acetaldehyde and acetic acid in the exhaust were measured, and the results shown in Table 2 and FIG. 5 were obtained. From these, despite the shutdown of the machine for several days, the initial values of ammonia, acetaldehyde, and acetic acid have not increased significantly compared to the previous time. Furthermore, when this machine is operated with respect to this air, ammonia, acetaldehyde, and acetic acid in the air are again reduced.
