However, it is desirable to operate the water purifier automatically for efficient management of the water purifier and safe use of the artificial kidney.

Therefore, the artificial kidney water purifier according to the embodiment of the present invention is provided with a control unit 600 for controlling each pump and valve, etc., it is possible to automatically operate the water purifier.

The controller 600 includes a signal processor 610 and an input / output interface 620. A microcomputer may be used as the signal processor 610, and a touch panel may be used as the input / output interface 620. Can be used. 3 illustrates an example of an operation screen of the input / output interface 620 using the touch panel.

Hereinafter, the function and operation of the controller 600 will be described in detail.

The controller 600 may operate and stop the water purifier, select automatic operation and manual operation, and receive an abnormal signal of each component to display an alarm signal. In addition, an operation screen of the I / O interface 620 may display operation data of each component in a graph or the like.

First, the controller 600 may set and control operations of the raw water supply pump 110, the high pressure pump 230, and the pure water pump 410. That is, it is possible to select automatic / manual operation and start / stop of the pump for each pump, and to set a delay time at the start or stop timing as necessary. In addition, for the raw water supply pump 110 and the pure water pump 410, one of the A pump and the B pump may be selected or replaced.

The output screen of the input / output interface 620 may be displayed to the user as a graph. For example, by receiving information on the water quality of the purified water from the conductivity meter 260 and displaying it on the output screen, the user can confirm the water quality of the purified water in real time.

Moreover, the operation | movement of various pumps and valves can be determined from such data, and an alarm signal may be generated when it determines with abnormal operation.

In addition, initial setting values of the low pressure switch LPS and the high pressure switch HPS may be set, and an operation time and a standby time of the heater 340 may be controlled.

Next, the automatic operation operation of the water purifier for artificial kidneys according to an embodiment of the present invention will be described in detail.

When the operation of the water purifying device is started from the control unit 600, the raw water valve 210, the raw water supply pump 110, and the high pressure pump 230 are operated in order, and the raw water is supplied from the pressure sensor PG of the pretreatment unit 100. Check that the inlet is at the correct pressure. At this time, the pure water pump 410 and the UV sterilizer 420 is turned OFF.

The high pressure pump 320 is controlled to start pumping after the raw water valve 110 is opened, and to control the raw water valve 110 to be closed after the pumping is stopped.

When pure water is automatically produced through the pretreatment unit 100 and the reverse osmosis treatment unit 200 and flows into the storage tank 310, the three-way valve 250 is opened when the conductivity is 10 s / cm or more, and the production water is discarded. . In some cases, the three-way valve 250 may be opened for a predetermined time so that the product water is discarded.

If the conductivity is 10 s / cm or less, the three-way valve 250 is closed and the production water flows into the storage tank 310. Alternatively, after the set time, the three-way valve 250 may be closed to allow the production water to flow into the storage tank 310.

Through the flow control valve (CV) installed in the reverse osmosis treatment unit 200 may be adjusted the amount of purified water.

Water purified through the pretreatment unit 100 and the reverse osmosis treatment unit 200 flows into the storage tank 310, and when the water level of the storage tank 310 reaches a predetermined level, the reverse osmosis unit stops.

The pure water pump 410 stops the pure water pump and activates the pressure sense operation alarm when the pressure not satisfied with the set value is maintained for a predetermined time or more, and the pure water pump 410 is automatically operated when the set value is satisfied.

At this time, the pure water pump 430 is operated by the timer only for a set time.

During the automatic operation, if the water level of the storage tank 310 reaches the upper-level, the standby state is maintained, and if the down to the middle-level, the automatic operation is repeated until the upper-level. When the water level is lowered to the lower level, the controller 600 displays an alarm signal.

The raw water valve 110, the raw water supply pump 100, and the high pressure pump 320 are operated in the order of the high pressure pump 320, the raw water supply pump 100, and the raw water valve 110.

The artificial kidney water purifier according to the embodiment of the present invention may automatically generate an alarm signal when a problem occurs in the operation of each component. The alarm signal may be displayed using an output screen or a warning light of the controller 600.

First, when the pressure of the incoming raw water is lower than the initially set pressure (for example, 5 kgf /), a low pressure alarm is generated. When the low pressure alarm is generated, in order to prevent a malfunction of the high pressure pump 230, the operation of the high pressure pump 230 is temporarily stopped and immediately restarts when the low pressure is released. However, if a continuous low pressure occurs, the system will shut down. On the other hand, if the incoming water pressure is higher than the initially set pressure, a high pressure alarm is generated and the system is stopped.

Next, when the water level of the storage tank 310 is at the low-level, a low water level alarm is generated. This is a case where the amount of water consumed is greater than the amount of water produced, so that the water in the storage tank 310 is insufficient. When a low water level alarm occurs, the valve or pipe is checked for leakage.

Next, if the pressure of the water supplied to the dialysis chamber 500 is less than the set pressure measured by the sensor, and generates a sensor alarm, check whether the leakage of the dialysis chamber 500 side, the raw water (pure) supply pump 110 Actions such as checking the operation state and checking the final filter 430 are taken.

Next, when there are abnormalities in various pumps due to overload, an alarm of a pump trip is generated, and measures such as a trip release are taken.

Next, if conductivity (for example, 10 s / cm) or higher than a set value is displayed from the conductivity meter 260, it is determined that the water quality is abnormal and an alarm is generated, so that the drain valve is opened.

As described above, the artificial kidney water purifier according to the embodiment of the present invention can quickly detect the abnormal operation of each component and take appropriate measures, so that the system can be stably operated.
