DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water quality management system for managing the water quality of a water purifier at a centralized water quality management center using a communication line, and belongs to the field of water quality management technology.

[0002]

2. Description of the Related Art In recent years, a water purifier is often connected to a water pipe in order to purify tap water supplied to each household or company to obtain better-quality cooked drinking water and the like. Is coming. This type of water purifier has various filters, and these filters are designed to remove dirt such as germs and eluate mixed in the tap water and to remove the bad smell of the tap water. Good quality cooked drinking water and the like can be supplied to the user.

[0003]

In this type of water purifier, however, the performance of the filter deteriorates after a certain period of use, so that it is necessary to perform maintenance such as replacement of the filter. Since the user of the water purifier often overlooks even if the performance of the filter has deteriorated, the time for replacement of the filter has passed, and the quality of the water that has passed through the purification section of the water purifier has been extremely deteriorated. Notice that the performance of the filter has deteriorated. Therefore, it is late to notify the water quality manager or the like of the information, and it takes time to arrange supplies such as filters and consumables.

Further, if such maintenance is delayed, the purity of the water passing through the purifying section of the water purifier becomes low, so that it is impossible to supply high-purity water with high safety.

Accordingly, the present invention detects deterioration of the performance of a plurality of water purifiers provided in water supply facilities at various places and changes in the quality of water passing through the purification section of each water purifier, and based on the detected values, detects each of them. It is an object of the present invention to provide a water quality management system capable of appropriately and collectively determining the purification capacity of a water purifier by a centralized water quality management means.

[Means for Solving the Problems]

In order to solve the above problems, a water quality management system according to the present invention is characterized in that it is configured as follows.

That is, the present invention relates to a water quality management system in which a plurality of water purifiers provided in water supply facilities at various locations and a centralized water quality control means are connected via a communication line. And at least one of a purity sensor for detecting the purity of water that has passed through the purification unit of the water purifier, and determining an abnormal state of the water purifier based on the detection value of the sensor on the water purifier side. Abnormality determination means for performing the determination and the determination result of the abnormality determination means on a regular basis.
Or at least one time when it is determined to be abnormal
In a communication means for transmitting to said water centralized management means via the communication line, the abnormality determination means when operated manually
The determination result is transmitted to the water quality central management means via the communication means.
And an operation switch for transmitting the data to the computer .

[0008] By configuring as described above, the present invention
According to the description , the following operation is obtained.

[0009] First, since the abnormality determination means for determining an abnormal state of the water purifier is provided in the water purifier side, if the purifying performance of the purifier is determined to be degraded by the abnormal judgment means, is determined as abnormal The abnormality determination result is automatically transmitted from the water purifier to the centralized water quality control means. Therefore, the administrator of the water quality management system can quickly perform maintenance such as replacement of the filter of the water purifier based on the determination result.

[0010] In the case where the abnormal condition of the water purifier is periodically judged by the abnormality judging means and the judgment result is transmitted to the centralized water quality managing means, similarly, the manager of the water quality managing system has a plurality of managers. The purification capacity of the water purifier can be accurately grasped, and maintenance can be performed promptly.

Furthermore, when installing both dirt sensor and purity sensor to the water purifier, it becomes degraded or purifying ability of the performance of a plurality of water purifier can be comprehensively judged by quality centralized unit, more precisely The purifying ability of each water purifier can be grasped.

[0012] And when operated manually,

[0027] The setting change of criteria abnormality determination is performed by operating the operation unit 25.

[0028] Next, a description will be given of the operation of the water quality management system 1.

[0029] First, when the tap water is supplied to the water purifier 2 from the water supply pipe 10, dirt is adhered tap water to non-twist film filter 7, the dirt adhered to the radio twisting membrane filter 7 is increased, The non-twist membrane filter 7 is clogged and the water supply pipe 1
A pressure difference between tap water and the first discharge pipe 11 occurs.
When the differential pressure is compared and detected by the dirt sensor 21 and the detected value is transmitted to the abnormality determination unit 23, and when the detected value exceeds a reference value previously set by the operation unit 25 of the abnormality determination unit 23, The determination unit 23 determines that the purification performance of the water purifier 2 has deteriorated. Then, the information is transmitted to the communication processing unit 24, converted into communication data by the communication processing unit 24, output, and transmitted to the modem 6 of the water quality detection device 3. The communication data transmitted to the modem 6 is analog-processed by the modem 6, and the analog-processed information is transmitted to the centralized water quality monitoring device 4 via the telephone line 5.

In the purity sensor 22, as in the case where the dirt sensor 21 detects dirt, the purity sensor 22 detects the purity of water.
To the abnormality determination unit 23
If the reference value set by the operation unit 25 is exceeded, the determination unit 23 determines that the purification performance of the water purifier 2 has deteriorated. Then, the information is transmitted to the communication processing unit 24, converted into communication data by the communication processing unit 24, output, and transmitted to the modem 6 of the water quality detection device 3. The communication data transmitted to the modem 6 is analog-processed by the modem 6, and the analog-processed information is transmitted to the centralized water quality monitoring device 4 via the telephone line 5.

The water quality detecting device 3 is provided with an abnormality determining unit 23.
A control unit (not shown) may be provided for determining an abnormal state of the water purifier 2 and periodically transmitting the determination result to the centralized water quality monitoring device 4.

Although the telephone line is used as an example of the communication line in the above embodiment, the same effect as described above can be obtained when a digital communication line other than the telephone line or a communication line for dedicated data is used.

Further, in addition to the above embodiment, it may be used provided only either the contamination sensor or purity sensor.

Furthermore, in the above embodiment, although the purity sensor is equipped in the purified water extraction pipe connected between the storage tank and the second opening and closing cock, connected between the activated carbon filter and the storage tank A purity sensor may be provided immediately after the third extraction pipe, that is, the purification section.

[0035]

As described above, according to the present invention, since the abnormality determining means for determining the abnormal state of the water purifier is provided on the water purifier side, the purification performance of the water purifier is deteriorated by the abnormality determining means.
