Description

AIR CLEANING DEVICE AND AIR CLEANING MONITORING SYSTEM USING THE SAME

The present invention relates to an air cleaning device installed in an indoor space, and more particularly to an air cleaning device effective in monitoring an indoor space environment and an air cleaning monitoring system using the same.

As conventional air cleaning monitoring systems, for example, techniques described in Patent Documents 1 to 4 are known.
Patent Document 1 is a technique for monitoring information from an air cleaner that cleans indoor dust at a monitoring center.
Patent Document 2 is a technique for monitoring incomplete combustion of a gas burner from temperature detection information by a thermistor.
Patent Document 3 is a system for monitoring fire information.
Patent Document 4 is a system that monitors the degree of removal of chemical contaminants in a clean room.

JP 2008-82661 A (Best Mode for Carrying Out the Invention, FIG. 1) Japanese Patent Laying-Open No. 2005-49077 (Best Mode for Carrying Out the Invention, FIG. 2) JP 2004-317103 A (Embodiment of the Invention, FIG. 6) JP 2004-263985 A (Example, FIG. 1)

This type of air cleaning monitoring system (for example, Patent Documents 1 to 4) monitors indoor dust information, temperature information of the thermistor to determine incomplete combustion of a gas burner, fire information, or contamination information in a clean room. All of them are used to monitor whether or not they are outside the allowable range. A security system that monitors crime prevention information and a system that automatically controls uncomfortable information such as temperature and humidity by an air conditioner are also known.
However, what is required as an indoor space environment is not limited only to whether or not the monitoring target is outside the allowable range.
For example, city gas, propane gas, etc. leak into the room, resulting in accidents such as poisoning, fire, and explosion. Therefore, it is necessary to take measures to prevent gas leakage. In general, a gas leak detector is often installed in the kitchen. This gas leak detector is installed near the ceiling surface when using city gas, and near the floor surface when using propane gas or LP gas. In either case, the gas leak detector sounds when detected.
The main causes of this type of gas leakage include 1) gas stove and water heater disappearing, and 2) instrument deterioration.
Here, in the case of 1), a gas leak occurs at a stretch and the indoor gas concentration rapidly increases. In the case of 2), the indoor gas concentration tends to gradually increase.
The gas leak detector described above mainly assumes the case of 1), and functions only when the indoor gas concentration suddenly rises. However, in the case of 2), the situation is dangerous (out of the allowable range). It cannot be detected until (Situation).
For this reason, for example, as in the case of 2), there is a strong demand for measures for quickly ascertaining the situation where the gas leakage gradually rises and preventing a gas leakage accident or the like in advance. .

Such a request is not limited to the above-described gas leakage, and the same applies to, for example, an exhaust gas leakage phenomenon caused by incomplete combustion of a combustion appliance.
That is, in recent years, there have been frequent cases in which combustion exhaust gas from gas / oil burning appliances used indoors leaks into the room, causing problems such as carbon monoxide poisoning. This type of combustion appliance is roughly classified into a closed type and an open type. The closed type discharges exhaust gas to the outside via a chimney, whereas the open type directly discharges exhaust gas into the room. In the former, it is important that the air in the chimney does not leak into the room, and in the latter, the deterioration of the combustion equipment, the decrease in the oxygen concentration in the room, or the generation of carbon monoxide and various VOCs due to the synergistic effect of both. You have to be careful. In either case, a one-time phenomenon rarely leads to a serious accident, and instrument deterioration with increasing burner use time causes serious indoor air pollution, for example in poisoning accidents.
In other words, there is a strong demand for measures to prevent accidents due to incomplete combustion.

Furthermore, in recent years, health damage caused by indoor chemical substance contamination has continued, and the sick house problem has become a social issue.
This type of sick house problem is caused by harmful gaseous chemicals such as formaldehyde and other VOCs (Volatile Organic Compounds) generated from building materials and furniture that partition the interior space, but residents are not aware of it. Moreover, there are many cases in which the cause of health is lost without knowing the cause.
Therefore, as a countermeasure against such a sick house problem, there is an increasing demand for monitoring how much pollutants such as VOC exist in the indoor space and to grasp early on the increase of the pollutant concentration in the indoor space. is there.
In addition, pets are often kept in the indoor space and ornamental plants are placed, but with this, microbial particles (ticks, molds, pollen, bacteria, viruses, etc.) are not present in the indoor space. There are many cases where it is necessary, and in some cases, it becomes an allergen or pathogen and causes health damage.
Even under such circumstances, there is also a demand for monitoring the state of the indoor space environment and grasping the existence state of microbial particles at an early stage from the viewpoint of preventing health damage caused by microbial particles.

In addition, gaseous substances generated from the human body such as exhaled breath and body odor contain chemical information such as the generated gas and its composition according to the human health condition. Against this background, there is an increasing demand for grasping the health condition of residents in the indoor space environment and responding promptly before serious health damage occurs.

Embodiment 1
FIG. 2 shows an overall configuration of Embodiment 1 of an air cleaning monitoring system to which the present invention is applied.
In the figure, the air purification monitoring system includes an air purification device 20 installed in an indoor space R in which a person M lives, and a management center 100 that manages gas leakage information and combustion information from the air purification device 20. ing. Reference numeral 50 denotes a combustion appliance installed in the indoor space R.
In the present embodiment, as shown in FIG. 3, the air cleaning device 20 has an air duct 21 as a cleaning device body in which an air flow passage 22 is defined, and an inlet louver 24 is provided at an inlet opening 23 of the air duct 21. In addition, an outlet louver 26 is provided at the outlet opening 25 of the air duct 21, and a coarse pre-filter 27 and a fine particle removing filter 28 for fine dust removal are arranged in the air flow passage 22 in order from the inlet side. Furthermore, a suction fan 30 for sucking air A is disposed in the air flow passage 22 between the pre-filter 27 and the particle removal filter 28.
A sensor 40 is disposed in the air flow passage 22 upstream of the particle removal filter 28 in the air flow direction. The sensor 40 includes the gas leak information (for example, city gas and propane gas) and combustion information. A gas sensor 41 for detecting (for example, carbon monoxide accompanying incomplete combustion) is used.
Here, the gas sensor 41 may be a detector configured to detect both gas leak information and combustion information, or may be a detector configured to individually detect each of them. In the present embodiment, the gas concentration of carbon monoxide is detected by the gas sensor 41 (40) as combustion information. However, before a serious accident such as carbon monoxide poisoning occurs, some kind of VOC or the like is detected. Gases such as noxious gases may be generated, so that a serious accident such as carbon monoxide poisoning may be prevented by using a specific gas sensor for detecting the specific gas.

In the present embodiment, as shown in FIG. 3, the management center 100 includes a management device 110 in which gas leak information and combustion information from the gas sensor 41 of the air cleaning device 20 is captured so as to be communicable. The factor substance is qualitatively and quantified based on the detection information managed by the management device 110.
More specifically, the management device 110 records and manages gas leak information or combustion information (gas concentration) detected by the gas sensor 41 in time series, for example, as shown in FIG. The two level values L ₁ and L ₂ (L ₁ <L ₂ ) are set in advance, and the time until the gas concentration reaches the level value L ₂ after reaching the level value L ₁ (t ₂ −t _{If 1} ) is shorter than a predetermined time, it is possible to determine that there is a possibility that gas leakage has occurred or incomplete combustion has occurred, although it is within the allowable range. Yes.
Then, as shown in FIG. 2, the management center 100 provides such gas leakage information or combustion information to the gas company 121 or the combustion appliance manufacturer 122, and receives the information from the gas company 121 or the combustion appliance manufacturer 122. Takes the provided gas leak information or combustion information (gas concentration) into the improvement discriminating device 130, and the improvement discriminating device 130 improves the air clean state of the indoor space R based on the gas leak information or the combustion information. It is determined whether or not it is necessary to perform the maintenance, and when it is determined that improvement is necessary, maintenance work is performed on the combustion appliance 50 installed in the indoor space R to be monitored.
As described above, the management center 100 collects information intensively, and when it is determined that the information is problematic or dangerous, it is possible to take an appropriate countermeasure or improvement.

Here, the improvement determination device 130 determines whether or not it is necessary to improve the air clean state of the indoor space R using the gas leak information or the combustion information (gas concentration) as it is, but is not limited thereto. A gas generation amount unique to each device such as the combustion appliance 50 is calculated, and based on the calculated gas generation amount, the state of the device is diagnosed, and the necessity of improving the air clean state of the indoor space R is determined. It does not matter if you do it.
For example, when using the aspect in which the combustion appliance 50 is an open type in the indoor space R, VOCs such as CO (carbon monoxide), HC (hydrocarbon), formaldehyde and the like as the combustion appliance 50 deteriorates and the indoor oxygen concentration decreases. The gas generation amount of (volatile organic compound) increases as compared with the normal time. For this reason, the gas concentration in the indoor space R increases. This abnormal concentration increase sometimes causes serious accidents such as CO poisoning.
Therefore, paying attention to such a gas generation amount, the following method has been found as a method for obtaining the gas generation amount of the pollutant to be monitored by analyzing the detection signal from the gas sensor 41 (40). .
That is, as shown in FIG. 4 (a), the gas generation amount of a certain pollutant in the meantime due to the increase value (dC) of the gas concentration in the indoor space R in a certain short time (dt) is shown in FIG. ).
In this way, by using the arithmetic expression shown in FIG. 4 (b), by measuring a minute indoor concentration change (dC) in a certain limited time (dt), it is possible to measure from a device such as the combustion appliance 50 in the meantime. The amount of gas generated can be determined with high accuracy. Thereby, abnormal pollutant generation | occurrence | production from apparatuses, such as the combustion instrument 50, can be detected.
Note that the arithmetic expression shown in FIG. 4B is a highly accurate calculation of the generation amount of factor substances such as substances generated from human bodies and pets, and contaminants from furniture and furniture, as in the embodiments described later. This makes it possible to detect the occurrence of an abnormal factor substance.

In the present embodiment, the management device 110 manages the gas leak information or the combustion information using only the information from the gas sensor 41 (40) installed in the air cleaning device 20. As shown in phantom lines in FIG. 2, information from a sensor 51 (for example, FID (abbreviation of Flame Ionization Detector) that directly monitors the combustion state) installed in the combustion instrument 50 is used. You may make it do.
Further, in the present embodiment, the gas sensor 41 (40) detects gas leak information or combustion information. However, the present invention is not limited to this. For example, as shown in FIG. Instead of the gas sensor 41 (40) of the air cleaning device 20, a collecting member 60 for collecting gas that becomes gas leakage information or combustion information passing through the air flow passage 22 is detachably mounted in the air duct 21. It may be.
Then, in the management center 100, as shown in FIG. 2 and FIG. 5B, the collecting member 60 is removed from the air cleaning device 20, and collected by the collecting member 60 removed by the collected substance analyzing device 111. The collected material (gaseous material in this example) is analyzed.
Here, as the collection member 60, a gas removal filter 61 (see FIG. 5A) capable of removing the gas to be collected or a collection tube 62 shown in FIG. 5B is used. Then, the gas removal filter 61 is removed, and the gas collected by the collection tube 62 is sampled and collected by the sampler 63 and brought into the management center 100.
And as the collection substance analyzer 111 of the management center 100, a gas chromatograph, a gas chromatograph mass spectrometer, a high performance liquid chromatograph, an ion chromatograph, etc. are adopted, and the collection member 60 (the gas removal filter 61 or the collection tube). The gas collected in 62) is analyzed.
Furthermore, in this embodiment, the gas company 121 or the combustion appliance manufacturer 122 determines whether or not improvement is required by the improvement determination device 130. However, the present invention is not limited to this. The discrimination process by 130 may also be performed, the discrimination result may be transmitted to the gas company 121 or the combustion appliance manufacturer 122, and maintenance work may be performed based on information provided from the management center 100. This also applies to the following embodiments.
