Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaning system, and more particularly to an indoor air cleaning system for removing complex pollutants, that is, gaseous pollutants, particulate pollutants and harmful microorganisms.

[0002]

[Prior Art] With the recent progress in building materials and the spread of air conditioning equipment, the space in which we live is becoming more and more airtight and sealed. For this reason, indoor air, as well as outdoor air, is now full of various pollutants. Gaseous pollutants (SOx, NOx,
COx, O ₃ , hydrocarbons, ammonia), particulate pollutants (Pb, Mn, Ca, Cl, Si, Cd, dust), odor pollutants (amine organic compounds), harmful microorganisms (bacteria, viruses, protozoa) , Molds, mites, etc.), and there are a wide variety of things such as those that are floating indoors and those that are sinking. These combined pollutions are certainly eroding our health. It is also reported that individuals are exposed to more pollution indoors than outdoors.

Originally, Japanese dwellings had a breathable structure, so sufficient ventilation was secured, but with the westernization of lifestyles, the dwelling of the dwellings increased, making indoor ventilation difficult. Has become. Stroke used for heating in winter
The amount of NOx in the room varies greatly depending on whether the exhaust gas type is an exhaust type or an exhaust type. An air conditioner with a filter and a fan heater are good as long as the filter is kept clean, but once dust is attached and the filter is clogged, it is not possible to adsorb the dust in the room. Alternatively, the dust adhering to the filter is scattered to the inside of the room and becomes a pollution source.

Further, when the operation of the air conditioner or the fan heater is stopped, moisture condenses on the filter, and molds and bacteria are easily propagated. Therefore, fungi and bacteria that have propagated through the filters of the air conditioner and the fan heater are scattered in the room and become a pollution source. With the spread of air conditioners and fan heaters, ultrasonic humidifiers have also become popular, but the atomization is based on the exciting action of ultrasonic surface waves and has no bactericidal effect. It is a source of pollution that is scattered.

On the other hand, cigarette smoke is of course one of the sources of pollution. 90% of cigarette smoke is gas, such as air, COx, and steam, and the remaining 10% is a particle component. In addition to tar, it contains about 20,000 kinds of compounds, and about 4000 kinds. The structure of the compound has been confirmed. The degree of pollution is large in closed spaces such as inside cars and conference rooms. As a countermeasure, ventilation using a ventilation fan or the like, and an air purifier are most often used. However, the air purifier is also removed by using a filter like an air conditioner or a fan heater, and it does not have a sterilizing effect, and it is troublesome to replace the filter, or if it is not replaced, it may become a pollution source. .

[0006] In the operating room of a hospital, the air in the room is also cleaned by using an air purifier. However, sterilization of bacteria and viruses is necessary in order to prevent hospital infections that have become a problem recently. It is difficult to prevent infectious diseases because it has no bactericidal function. Commercial air purifiers are not enough. In addition, infectious diseases are caused by overseas travelers and returnees,
The number of cases brought in by imported goods such as food has been increasing in recent years, and it is necessary to clean various sealed indoor air such as toilets in restaurants, restaurants, customs, and inspection rooms for imported goods.

[0007] The air purifier is a dust collector that collects dust with a positive load and collects dust with a negatively charged filter, and a static collector that collects dust with a fan. There are three types: an electric filter type and an electron ion type in which dust is charged negatively and is adsorbed by a filter of a positive electrode portion.

However, all of the above three types of air purifiers seem to be effective for removing tobacco smoke, pollen, and other polluting causes, but cannot remove gaseous substances such as COx and NOx. Things like indoor dust, mites, molds,
Microorganisms such as bacteria, protozoa and viruses have drawbacks such as poor removal efficiency.

[0009]

As a conventional air cleaning method, there are a circulation method in which dirty air in a room is passed through a filter to be cleaned and discharged again into the room, an exhaust type stove, and the like. It is roughly classified into two types, that is, an outside air introduction method in which outside air is passed through a filter and introduced into a room such as a fan heater and a ventilation fan. The former circulation method is NOx or C
Gaseous substances such as Ox cannot be removed. Further, it is less effective when mites, molds, bacteria, protozoa, viruses, dusts, etc. are immobilized and present in a specific place in the room.

As places where mites, molds, etc. exist,
Examples include filters for floors, clothes, futons, carpets, tatami mats, furniture gaps, air conditioners and air purifiers. In particular,
There is a problem that filters such as air conditioners and air purifiers take in mold and bacteria suspended in the room and, as a result, propagate these on the filters.
If the filter can be cleaned at all times, the problem can be solved, but there is a problem that it takes a lot of time and effort for the user.

Since dust and the like are adsorbed at a specific place,
It will be difficult to remove completely unless it is suspended in the air. Vapors such as volatile organic compounds, insecticides, and insect repellents used as solvents in paints and building materials have a problem that it is difficult to remove them by the former circulation method.
In order to remove the dust, volatile organic compounds and the like, the latter outside air introduction method of exchanging indoor air with outside air is most desirable.

However, the removal efficiency of the intake of the outside air and the exhaust of the indoor air differ depending on the positions of the inlet and the outlet, and have no effect on the fixed mites, molds, bacteria, protozoa, viruses, dusts, etc. Things can be mentioned. For example, a ventilation fan is provided to remove only a specific pollutant generated in a specific place such as a kitchen, a bathroom, a toilet, a smoking place, and has a drawback that it is not effective for other pollutants. In addition, the ventilation fan,
Ignore outside air pollution, except dust, NO
There is also a problem that x, COx, bacteria, protozoa, viruses, molds, etc. are re-introduced from the outside to the inside of the room.

The object of the present invention is to solve the above-mentioned problems of the prior art.

This operation is repeated several times to complete the operation. These operations are performed by opening a solenoid valve by setting a predetermined time with a timer (not shown).

The above suction operation will be described in more detail. A dust sensor (not shown) is usually provided at the discharge port 11, and the dust sensor is operated or the user operates the dust sensor.
The discharge preparation chamber 12 is connected to the vacuum pump 10 to make a negative pressure by turning on the switch at the desired time by the user or by a timer or remote operation. The magnitude of the negative pressure at this time depends on the volume of the operating room O and the discharge preparation chamber 1.
760mmH of atmospheric pressure, depending on the volume ratio with 2
It is desirable to make a difference of 50 mmHg or more with respect to g. This negative pressure can create a strong air flow.

By means of the pressure sensor-9, the discharge preparation chamber 1

From the outlet 11, dust, mold, mites, etc. in the operating room O
Bacteria, protozoa, viruses, etc. are sucked into the discharge preparation chamber 12, and then the electromagnetic valve 13'a is closed again.

By performing the above operation intermittently, the operating time can be shortened, and efficient discharge can be achieved. Dust, mold, etc. once inhaled into the discharge preparation chamber 12
Mites, bacteria, protozoa, viruses, etc. are introduced into the sterilization chamber 5 when the discharge preparation chamber 12 is set to a negative pressure.

As described above, the shutoff of each chamber is performed by the control by the measurement value of the pressure sensor 9 by the pressure control device 8 and the control by the timer (not shown).

On the other hand, clean air is introduced into the operating room O. The method will be described below. The outside air is sucked into the charging chamber 3 by the compressor-1. A negative ion generator (not shown) is attached to the charging chamber 3, and negative charges are added to contaminants in the outside air such as dust, mold, mites, bacteria, protozoa, and viruses in the charging chamber 3. .

As the blower 7, a device having a temperature adjusting function is usually used. A comfortable temperature is introduced into the operating room O.

When introduced into the room, it may be jetted using a plurality of nozzles or blades, or may be once compressed and then jetted. By increasing the injection speed as much as possible and releasing it into the room, contaminants such as dust, mold, mites, bacteria, protozoa, and viruses that are adsorbed in the room can be lifted up and sucked into the discharge preparation room 12. Can be made easier.

At this time, since the pressure in the operating room O rises, the differential pressure between the discharge preparation chamber 12 and the discharge preparation chamber 12 is further increased, and the suction preparation chamber 12 is easily sucked. Also, a pressure sensor 9 may be provided to monitor the pressure rise in the chamber, and when the pressure rises to a certain level, the discharge preparation chamber 12 may be exhausted and sucked.

Next, the effect of this embodiment will be described. First, indoor dust, mold, mites, bacteria, protozoa, viruses and the like are present on floors, clothes, futons, carpets, tatami mats, furniture crevices, and the like. These are present in a wide range of the room, especially near the floor. Therefore, the outlet for these pollutants should be near the floor.
Desirably, it is integrated with a floor, such as a tile, tatami mat, carpet, or floor. Alternatively, it may be installed on the wall near the floor. In such cases,
The resulting air flow passes through the tatami and carpet gaps and is even more effective.

The discharge port has, for example, a plurality of holes on the floor, and suction is performed through the holes. Except for discharge, this hole may be closed to function as a floor. Thus, conventionally, an air cleaning system effective only for removing a specific pollutant whose source is limited, such as smoking and pollen, has been provided. An effective system for can be provided.

[Embodiment 2] Another embodiment of the indoor air cleaning system according to the present invention will be described with reference to FIG. FIG. 2 is a schematic explanatory view of another embodiment of the air cleaning system according to the present invention. In the present embodiment, an air cleaning system in the spaceship will be described. In the figure, the same reference numerals as those in FIG. 1 are equivalent parts, and therefore detailed description thereof will be omitted and only new reference numerals will be described. 16 is a catalyst chamber. Since this embodiment is almost the same as [Embodiment 1], the description of the same parts will be omitted and different parts will be described.

As shown in FIG. 2, in this embodiment, the introduced outside air sterilized in the sterilization chamber 5 is introduced into the catalyst chamber 16 for processing. In the catalyst chamber 16, the complex contaminants in the introduced outside air are adsorbed and removed for cleaning. The clean introduced outside air is diffused into the room using the air blower 7 so as to be scattered in all directions from the ceiling or the wall surface near the ceiling.

Here, for example, when activated carbon is used as the catalyst, it is possible to remove the amine-based organic matter, ammonia, aldehydes, hydrocarbons, ozone, and COx. After the removal, the treatment and the exhaust are performed in the same manner as in [Example 1]. Similar to [Example 1], this example can also provide an effective system against all pollutants in the room.

[Embodiment 3] Still another embodiment of the indoor air cleaning system according to the present invention will be described with reference to FIG. FIG. 3 is a schematic explanatory view of still another embodiment of the air cleaning system according to the present invention. In this embodiment, an air cleaning system in a child room will be described. In the figure, the same reference numerals as those in FIG. 1 are equivalent parts, and therefore detailed description thereof will be omitted and only new reference numerals will be described. 17 is a heat exchanger. Since this embodiment is almost the same as [Embodiment 1] and [Embodiment 2], the description of the same parts is complicated and therefore omitted, and the different parts will be described.

As shown in FIG. 3, in this embodiment, the introduced outside air from which moisture has been removed from the duct between the dehumidifying chamber 6 and the blower 7 and the exhaust from the discharge preparation chamber 12 are heat-exchanged by the heat exchanger 17. However, the piping path differs depending on the model of the heat exchanger 17. Air is introduced from outside using the compressor-1. The introduced air is sterilized in the sterilization chamber 5 after collecting dust in the same manner as in [Example 1] and [Example 2]. After sterilization, ammonia, NOx, COx, ozone and SOx are adsorbed and removed in the catalyst chamber 16, and then water is removed in the dehumidifying chamber 6.

After the moisture removal treatment, the outside air is heat-exchanged with the indoor exhaust sucked from the discharge preparation chamber 12 through the heat exchanger 17, and then compressed by the air blower 7 to be blown into the room to be stirred. In this case, the solenoid valve 13f opens and closes the outside air flow path to the heat exchanger 17 as needed. Similar to [Example 1] and [Example 2], this example also provides a system effective against all pollutants in the room and at the same time improves the thermal efficiency.

Although the respective embodiments of the present invention have been described as above, the comparison of the dust collection rate between the conventional air cleaning system and the air cleaning system of the present invention will be shown numerically. The room air was measured before the device was activated and three hours after the device was activated. The measurement method was a relative display method by absorption spectrophotometry by collecting and collecting the complex pollutants in the room air with a filter paper. As a result, in the conventional air cleaning system, the dust collection rate was only about 50%, but in the present invention, the dust collection rate of more than 70% was obtained.
