Description

Method for informming filter exchange time in water purifier}

The present invention relates to a water purifier, and more particularly, to detect the amount of purified water in the water purifier and to accurately manage the replacement time of the water filter installed inside the water purifier, thereby providing a hygienic and economic benefit to the consumer. The present invention relates to a notification method of filter replacement time of a water purifier.

In general, the water purifier is configured to pass the non-purified water through the nonwoven fabric filter, the ultra membrane filter, the precarbon filter, the post carbon filter, the post filter, etc. In addition, it is well known that sanitary water purification is provided through various water purification methods or apparatuses.

On the other hand, the filter of the general water purifier, after purifying water of 1800 ~ 2000ℓ (Ministry of Environment, water purifier quality inspection standard value), the end of life as a filter will be replaced with a new one.

However, the existing water purifier does not have a device that can measure the amount of water purified by the filter, there is a disadvantage that the replacement time of the filter does not match the life.

That is, in the related art, the filter is not replaced after detecting that the filter life is completed through water purification. Instead, the filter replacement cycle is 2 months, 3 months or 6 months, 8 months, 12 months, etc. If it meets the predetermined cycle according to the product specification during the cycle, it will be replaced.

Therefore, conventionally, regardless of the case where the volume of water used by the water purifier is small in the replacement cycle (that is, the amount of purified water is small) or when the volume of water used by the water purifier is actually very large (that is, the amount of purified water is large) in the replacement cycle. Filter replacement is performed uniformly, causing problems in a sanitary and economic manner.

In other words, when the filter replacement time has passed because of the large amount of purified water, there is a problem in which the user drinks the water that is not properly purified, and when the filter is replaced while the filter replacement time is not yet practically small. There was a problem of economic and financial losses.

In addition, when the filter replacement time is over due to a large amount of purified water, water may be contaminated secondary due to the filter, and when the filter is replaced when the filter is not replaced due to the small amount of purified water, it is inefficient in resource utilization and environmental. There were many problems, such as increasing the amount of waste generated in terms of.

Accordingly, the present invention has been proposed to solve all the problems occurring in the conventional general water purifier as described above, and an object of the present invention is to detect the purified amount of the water purifier and to replace the water filter installed in the water purifier. It is to provide a method of notifying when to change the filter of the water purifier so that it can be beneficial to the consumer hygienically and economically by ensuring accurate management.

Reference numeral 5 denotes purified water amount detecting means provided on the flow path of the purified water unit 2, and reference numeral 6 controls the operation of the water purifier according to the purified water amount detected by the purified water amount detecting means 5. A control means is shown.

Further, reference numeral 7 denotes a liquid crystal display for displaying the purified water amount, time, stop message, etc. under the control of the control means 6, and reference numeral 8 indicates an alarm when the reference purified water amount is exceeded under the control of the control means 6; An alarm generating unit for generating a signal is indicated, and reference numeral 9 denotes a memory for storing purified water amount data, first and second set values SV, and the like, detected under the control of the control means 6.

The water purification unit 2 is composed of a pre-filter 200, a pre-treatment carbon filter 201, a post-treatment filter 202, a post-filter 203, etc., The purified water amount detecting means 5 may be installed anywhere between each filter and in front of or behind the purified water unit 2, but it is most preferable that the purified water amount detecting means 5 is provided on a flow path between the prefilter 200 and the pretreated carbon filter 201. .

In addition, although not shown in the drawings, a discharge unit for discharging a proper amount according to a user's selection is provided at a predetermined position of the main body, and the discharge unit is further provided with a solenoid valve for preventing the discharge of the purified water to the outside.

In addition, although not shown in the drawings, a lamp for visually informing the replacement time of the filter is further provided.

The water purifier to which the present invention configured as described above is applied turns the rotary blade installed inside the flowmeter while passing water through the flowmeter in the purified water detection means 5 installed on the flow path of the water purification unit 2, and thus the rotation speed of the rotary blade. The amount of purified water is detected in proportion to.

The detected purified water amount is transmitted to the control means 6, which stores the stored water in the memory 9 and periodically stores the purified water amount stored in the memory 9 and the first and first stored in the memory 9. 2 Set value SV is compared and it is determined whether it is an excess integer.

When the amount of purified water exceeds the first set value, the alarm generator 8 is operated to generate a primary alarm, thereby allowing the user to first recognize the filter replacement time.

In addition, when the purified water amount exceeds the second set value, the alarm generating unit 8 is operated to generate a final alarm, and at the same time, a stop message is displayed through the liquid crystal display unit 7, and the solenoid valve in the discharge unit. To prevent water from being discharged to the outside.

Hereinafter, a preferred embodiment of the present invention will be described with reference to a water purifier to which the present invention operating as described above is applied.

2 is a flowchart illustrating a method of notifying filter replacement time of a water purifier according to the present invention.

As shown in the drawing, when power is supplied, checking whether data exists in the memory (S101), and in the initial state in which no data exists in the memory, initializing the memory and storing data set by the user ( S102), after the data magnetic field or when there is data in the memory (S103) and reading the data in the memory (S103), the first set value (100%) set for notification of the purified water amount and filter replacement time of the read data (S104 to S105) for notifying the filter replacement time first by generating an alarm when the purified water amount reaches the first set value (S104 to S105), and when the purified water amount exceeds the first set value, the purified water amount and the final filter Compare the second set value (110%) set for notification of exchange time and generate an alarm when the purified water amount exceeds the second set value. Finally notifying the user, displaying a stop message, and simultaneously shutting off the solenoid valve to prevent water discharge (S106 to S107); and in a state in which the purified water does not exceed the second set value, When the correction is required, changing the hours and minutes in response to the user's operation (S108 to S109), and checking the time and storing the daily purified amount data in the memory when the checked time reaches 12 am (S110). S111), and if the date is checked and the first day of the month is reached, storing monthly purified water amount data in the memory (S112 to S113), and storing main data (S114).

In the method for notifying the filter replacement time of the water purifier according to the present invention thus made, first, in step S101, the control means 6 checks whether data stored in the memory 9 exists.

If there is no data in the memory as a result of the checking, that is, when the filter is first operated after replacing the filter with a new one or when the product is first operated after the product is shipped, the initial setting data is stored in the memory in step S102. For example, the present constant amount PV is set to 0, the constant amount set value SV is set to 3,000EA, the current set value PV is set to 0, and the data set value SV is set to 238 ( 34 weeks).

On the other hand, if there is data in the memory as a result of the checking, the memory data is read in step S103.

The data judged here reads the constant amount present value PV, the constant amount set value SV, the data present value PV, the data set value SV, and the like.

Next, in step S104, the first set value set in advance is compared in order to inform the filter replacement time firstly of the purified water amount. Here, the first set value is set to 100% of the purified water amount.

If the first set value (100%) set in order to inform the filter replacement time as a result of the comparison as the result of the comparison is primarily the same, a primary alarm is generated through the alarm generator 8 in step S105. Here, in the method of notifying the first filter replacement time, an alarm is generated for a predetermined time by turning the beeper on for 1/4 second on and off for 8 seconds, and the FIL (abbreviation indicating filter) message is prescribed on the liquid crystal display 7. Display every 2 seconds for time. In addition, the yellow LED flashes 1/2 second on / 1/2 second off to inform the user of the first filter replacement time. Of course, in normal condition, the green LED turns on to inform the user that the water purification is normally performed.

On the other hand, after notifying the first filter replacement time as described above, or when the purified water amount is not the same as the first set value, the second preset value preset in order to finally inform the purified water amount and filter replacement time read out from the memory in step S106. Compare Here, the second set value is set to 110% of the purified water amount.

When the purified water amount read as a result of the comparison is larger than the second set value (110%) set to finally notify the filter replacement time, the final alarm is generated through the alarm generator 8 in step S175. Here, the method of notifying the final filter replacement time generates an alarm for a predetermined time by turning the beeper on for 1/4 second on and off for 2 seconds, and displays a FIL (abbreviation for filter) message on the liquid crystal display 7. At the same time, it displays a message of suspension. In addition, the red LED flashed separately by 1/2 second on / 1/2 second off to notify the user of the final filter replacement time, and at the same time the solenoid valve in the discharge part is shut off so that the purified water is discharged to the outside. To prevent them. Here, the solenoid valve is shut off because the purified water in the state in which the filter function is paralyzed may increase contamination. Of course, when the filter is replaced with a new one, it is preferable to discard the purified water and clean the storage tank before use.

If the result of the comparison of step S106 is less than the second set value of the purified water, go to step S108 to check whether time correction is required. If time correction is required, go to step S109 to determine the hours and minutes. Here, since the time correction method is the same as the time correction method of a typical electronic product, its detailed description is omitted.

After the time correction or when the time is not corrected, it is checked in step S110 whether the current time is 12:00 AM. If the current time is 12:00 AM, the daily unit data is stored in step S111. The daily data storage will be described later in detail.

In addition, if the data is stored in the unit of the day or if it is not at 12:00 AM, the process moves to step S112 to check the date, and confirms whether the checked date is one day. If the check result is 1 day, the process moves to step S113 to store monthly data. The monthly data storage process will also be described in detail later.

In addition, if the monthly data is stored or if it is not one day, the main data (for example, the present purified water amount) is stored in step S114, and the process moves to step S104.

On the other hand, if the interrupt occurs during the operation as described above to process the interrupt generated through the process as shown in FIG.

As shown in FIG. 3, in the interruption process, when an interrupt occurs in a state in which the water purifier normally operates, analyzing the interrupt type (S201) and displaying the current time when the analysis result is a time display interrupt. Step (S202 to S203), displaying the purified water amount when the analysis result is an integer quantity display interrupt (S204 to S205), displaying the error contents when the analysis result is an error display interrupt (S206 to S207), Transmitting check data to a memory in response to a read request (S208 to S209) in the case of the analysis result data transmission interrupt; and storing data generated during the water purifier operation in the memory in the case of the data storage interrupt in the analysis result memory (S208). S210 to S211).

In the interrupt processing performed in this way, first, when an interrupt occurs in step S201, the generated interrupt is analyzed.

Then, it is checked whether the interrupt generated in step S202 is an interrupt that requires time display. If the check result is an interrupt that requires time display, the current time is displayed in step S203.

Next, if the generated interrupt is not an interrupt requiring time display, it is checked whether the interrupt generated in step S204 is an interrupt requiring a constant amount display. If the interrupt generated as a result of the check is an interrupt requiring display of the integer amount, the integer amount up to the present is displayed in step S205.

If the generated interrupt is not an integer quantity display interrupt, it is checked in step S206 whether the interrupt requires an error display. In the case of an interrupt requesting an error display as a result of this check, the error content is displayed on the liquid crystal display unit 7 in step S207.

If the generated interrupt is not an error display interrupt, it is checked in step S208 whether it is an interrupt requesting data transmission. If the check result is an interrupt requesting data transmission, the process moves to step S209 to execute a data transmission routine.

The data transmission routine is as shown in FIG.

As shown in Fig. 4, in step S301, it is checked whether it is an interrupt requesting daily meter reading data transmission. If the check result is an interrupt requesting daily meter reading data transmission, the ID, set value (SV), current time, and integer amount ( Transmit PV).

If it is not the daily reading data transmission request, it is checked whether the interrupt requesting monthly reading data transmission is performed in step S303. If the checking result is an interrupt requesting transmission of monthly reading data, 90 days data and Send monthly data.

On the other hand, in Fig. 3, if the result of the check in step S208 is not a data transmission interrupt, the process moves to step S210 to check whether it is an interrupt for requesting data storage in the memory, and if it is an interrupt for storing data in the memory as a result of the check. In step S211, the data storage routine is executed.

The data storage routine is shown in FIG.

As shown in Fig. 5, it is confirmed in step S401 whether the ID recording signal is applied, and in the case of the ID recording signal, ID data is stored in the memory 9 in step S402. For ID, 6-digit number is applied for convenience.

Next, in step S403, it is confirmed whether the set value (SV) recording signal is applied. If the result of the check is the set value write signal, the set value data is stored in the memory 9 in step S404. The set value here represents 0 to 9999 liters for the filter constant amount.

Further, in step S405, it is confirmed whether the purified water amount (PV) recording signal is applied. If the result of the check indicates that the purified water amount write signal is positive, the purified water amount data detected in step S406 is stored in the memory 9.

In step S407, it is confirmed whether or not the time recording signal is applied, and when the result of the check is a time recording signal, time data obtained by detecting the purified water amount is stored in the memory 9. Here, the time data stores the time data in memory in the order of year, month, day, hour, and minute.

According to the present invention "filter replacement time notification method of the water purifier" described above, it is possible to accurately notify the user of the filter replacement time, there is an advantage that provides a user benefit hygienically and economically.
