It is preferable to configure the integrated type, and to configure the communication between the filter life checking device and the control unit by receiving power as the connector is exposed by connecting only the connector.

When the power is supplied and ready for operation, the control unit 9 checks whether the filter is installed, checks whether the filter life checking devices are installed, and checks the manufacturer, capacity and function of the currently installed filter from the filter life checking device. Check whether the filter is set to be usable by the ionizer and check whether the normal filter is adopted and control the display.

Each solenoid valve is controlled to select one of the filtered integers to withdraw. This mode-specific solenoid valve control is as described above with reference to FIG.

Since the present invention is for displaying the filter replacement time, the flow rate passing through the filter is checked through the flow meter 4, and the life of the filter is calculated by the filtering flow rate using a predetermined filter life calculation algorithm. When the life of each filter is calculated, the filter life information is transmitted to the filter life checking devices 3a and 5a to be stored in the nonvolatile memory, respectively.

Then, the control unit 9 displays the current filter life and each operation state through the display device 100.

4 is a front view of a display device for displaying the remaining filter usage of the ionizer according to the present invention.

The ionizer display device 100 can display each operation state under the control of the control unit 9 and can indicate the filter replacement time by displaying the filter life, that is, the remaining filter use, which is a key feature of the present invention. It would be.

As shown in FIG. 3, the raw water inflow display unit 101 which displays the raw water inflow, the volume display unit 102 which displays the volume, the upper water outlet display unit 104 in the water extraction direction during water purification, and the lower water outlet display unit 103 in the purified water And a check display unit 105 for an operation abnormality such as insufficient flow rate or no filter installation, a cleaning display unit 106 for displaying a cleaning operation state, a water discharge flow rate display unit 107 for displaying the discharge water flow rate, and a pH set value.

The display device 100 as described above is easily displayed using a graphic of each display function through the LCD, and a lower portion of the display device is provided with a button for driving operation as a quench cap to facilitate driving operation.

In the present invention, the display device 100 is provided with the remaining amount of display unit 111, 110 of the filter 1, the filter 2 to inform the filter replacement time, which is the control unit 9 is the filter life confirmation device (3a) Control life information is read and displayed from " 5a ".

5 is a flowchart illustrating a method for displaying a filter remaining amount of an ionizer according to the present invention.

When the power is turned on to start the operation of the ionizer, the control unit 9 reads the filter information from the filter life check device (S1), checks the filter information (S2), and determines whether the filter is normally installed. ; When the filter is normally installed in the first step, the filter life information is read from the filter life check device (S3), and the filter life information is checked (S4) to determine whether the filter life remains normally instead of the end of life or an error. Judging a second step; When the filter life is normal in the second step, the normal operation of the ionizer is controlled, and the discharge flow rate of each filter is measured to calculate filter life information according to the discharge flow rate from the remaining filter life information (S5). Step 3; When the filter life information according to the discharge flow rate is calculated in the third step, the filter life information is periodically transmitted to the filter life checking apparatus, and the fourth step of restoring the filter life information (S6) is performed.

The first step is a step in which the control unit 9 reads filter information by accessing the filter life checking devices 3a and 5a attached to the respective pretreatment filters 3 and the post-treatment filters 5. If, as a result of the filter information check (S2), if there is no filter information or no filter is installed, an error display and a corresponding error message are output through the speaker 23. At this time, the control unit 9 stores filter information such as the type, manufacturer and capacity of the filter that can be installed in the ionizer, and the type of filter that is allowed to mount the filter information read from the filter life checking devices 3a and 5a. , It checks the capacity and judges whether it is normal, and if it is not normal, it outputs the corresponding message and controls the check display unit 105 of the display device 100 in the state of stopping the operation of the ionizer to indicate that it is a filter error. .

Further, in the first step, the control unit 9 reads filter information from the filter life checking device 3 and 5 to determine whether the filter manufacturer and the filter are available models, which is an ionizer. It utilizes the manufacturer and model information set in advance and controls whether the filter mounted on the ionizer is a genuine filter or an unusable filter to restrict the operation of the ionizer.

When the filter life check device is attached to the filter, the filter life check device (3) (5) does not erase the filter life data even when power is not supplied, and at the same time as the filter life check device, Filter information and filter life information are stored and managed by using a nonvolatile memory that prevents the use of the expired filter.

In the second step, the filter life information stored in each of the filter life checking devices 3a and 5a is read (S3), and it is checked whether or not the filter life information is normal for the operation of the ionizer (S4). When the filter life information is normal, the remaining available amount of the filter is displayed on each of the filter life display parts 111 and 110 of the display device 100. The remaining amount is indicated by the filtering capacity (in liters L).

If only the remaining available remaining capacity of the filter life information is less than the normal operation of the ionizer, an error is displayed and a message indicating that it is time to replace the filter. If the filter life information cannot be read, an error is displayed to indicate that the filter life information is an error.

At this time, if the filter life information is less than the usage limit value, or if the filter life check device is detached and the life information cannot be read, an error is displayed and the flow rate discharge algorithm S10 is performed.

6 is a flow rate discharge algorithm when removing the filter life confirmation device according to the present invention. As described above, the flow rate discharge algorithm is performed when the filter life information is zero and the filter life information is zero, the life is expired, or when the filter life information is removed or the filter is replaced or the filter life check device is removed.

The raw water control solenoid 2 is controlled to block the water inlet valve, and the purified water solenoid 7 and the ion solenoid 6 are controlled to open the purified water valve and the ion valve (S11). Then, it is determined whether the remaining water discharge time is greater than or equal to a predetermined set time (S12), and maintaining the step of closing the inlet valve and opening the purified water valve and the ion valve. Then, when the residual water discharge time is more than the set time, each valve is notified to replace the filter by notifying that the residual water discharge is completed while performing the step (S13) to block the operating power to prevent heat dissipation.

That is, the control unit 9, by removing the connection between the filter life confirmation device (3) (5) and the control unit 9 when the filter is replaced, the filter automatically operates the flow opening and closing device to shut off the water and discharge the remaining water. It controls to prevent the water remaining in the filter from overflowing or inflow of foreign matters, and stops the operation of the flow switchgear after a certain time so that no heat is generated in the flow switchgear.

In the third step, when the filter life information is normal, the flow rate check is performed using the flow rate sensors 3b and 5b of the filter while the ionizer is operating normally to calculate each filter life information. This is to calculate the life information for each filter, the discharge flow rate of each filter is detected using the flow meter 4 at regular intervals, and the remaining life of the filter is calculated based on the discharge flow rate.

The fourth step transmits and stores the filter life information periodically calculated in the third step to the corresponding filter life check apparatus.

The normal operation is to set the filter life of the pretreatment filter 3 to 6000L and the filter life of the post-treatment filter 5 to 9000L as initial filter values, for example, when water passes through each filter. The pulse according to the flow rate is input through (4), and the control unit 9 calculates the number of input pulses periodically (500 msec) to reduce the filter life. In the step S4 of checking the filter life information, when the remaining filter usage is 70L or less, a voice message, "It is time to replace the filter. Please prepare for replacement", is output.

Accordingly, the control unit 9 periodically stores the filter life in the filter life checking device in consideration of the used flow rate and periodically checks the stored filter life so as to replace the filter by voice and screen when the filter life is short. When the filter reaches the end of its life, allow it to be used up to a certain amount and then stop using it.

The error judgment is that if the filter is not connected when the ionizer is turned on and the filter information or the filter life information cannot be read, the filter life display parts 111 and 110 can be used while the check display part 105 is lit. The filter indicators 110 and 111 (filter 1 and filter 2) are periodically blinked while the remaining amount is displayed as 0000L and E1 (no filter error) is displayed in the flow rate.

Filter life check If a write error occurs when sending and saving the filter life information to the device, a check is displayed and if the last value read is 0, it is 0000L. If the value is greater than 0 and less than the filter maximum life value, the value is read. If it is greater than the maximum service life value, the relevant residual amount L is displayed and it blinks periodically, displaying E3 (write error) in the flow rate.

As described above, in the present invention, the filter life checking device (3) (5) is attached to each filter and attached together with the filter, and the filter life checking device (3) (5) and the main control unit (9) of the ionizer are used. The controller 9 checks whether the filter is installed, the filter information, and the filter life information through the wired or wireless communication, and displays the information on the display device 100. The remaining amount of filter remaining is periodically checked by checking the flow rate of each filter. The calculated filter life information is stored in the filter life checking apparatus. When the power is turned on, the filter life information is read from the filter life check device to continuously display the filter usage level. If an error occurs, an error indication is displayed and the remaining usage of the filter is less than or equal to the preset operating limit value (for example, 70L). If so, it will indicate when it is time to replace the filter and inform you with a message. It also outputs messages periodically.

On the other hand, the control unit 9 implements a clock function to automatically record the filter usage information by date when the filter is replaced, providing a filter usage history, so that the user can know the filter usage history and the user can replace the normal filter. The period can be predicted.
