Description

Filter exchanging time indication equipment

The present invention relates to a filter replacement display device. Even though a filter for each manufacturer having a different effective constant is installed, the effective constant quantity of each filter can be programmed so that the effective constant quantity can be compared with the flow rate value for optimum filter replacement. The present invention relates to a filter replacement display device which improves the reliability of the device by informing a user of a time period so as to replace the available filter in advance to prevent waste of resources and to prevent the use of a filter having a reduced filter function.

In general, filters for directly purifying groundwater or household water purification are arranged in a row, and each filter is connected to each other through a connecting pipe so that raw water can be purified step by step through the filter in turn. .

Since the plurality of filters are raw water passes in order, each filter replacement time is different, and accordingly, the use period of the filters is also different, thereby causing a waste of resources by replacing the available filters when performing a batch replacement. This was raised.

In order to solve the above problems, there is a slight difference in each manufacturer, but after a certain period of time, the A / S agent is dispatched according to the standard that appears in its own database, inviting consumers to replace the filter or using a timer. After the measurement, the filter was replaced after a certain time.

On the other hand, when a plurality of filters are installed, the first filter, the second filter, the third filter, and the fourth filter, through which the raw water passes first, have different filtration amounts. As a result, it is not a very efficient method to replace the filter by a timer. Therefore, the improved conventional technique sets the effective constant amount according to the filter filtration capacity of the first filter. By checking the amount of raw water filtration, it was estimated by experiments and experience that the filtration capacity of the filter is lowered when a certain amount, and the filter is replaced when the raw water more than the effective water is filtered, accordingly, the second filter, the third filter, and the fourth filter also If a certain amount of effective constant is set and the effective constant is exceeded, filter The ring was time to let the user gege.

As described above, the exchange time notification means by the timer and the filter replacement time notification means by the effective water amount are calculated by the manufacturer regardless of the amount of purified water used by the consumer and the quality of raw water supplied to the region. For example, there is a risk that consumers with high levels of contaminated water or high consumption of purified water will have to use contaminated filters. As a result, there is a problem that economic loss or waste of resources is caused.

The present invention devised to solve the above problems, the filter's filtration capacity is lowered when the filter is used according to the degree of pollution of the raw water, and the flow rate of the purified water decreases, and the flow rate used by the consumer is calculated for each filter. It warns consumers when to change filters compared to the effective water and flow rate values, so that filters can be replaced at the optimal time, enabling economical waste and resource savings, as well as the use of filters that guarantee optimum filtration capacity. The purpose is.

The above object is to be installed in any one of the connection pipe 104 connecting between the water inlet pipe 102 and the at least one filter 103, the water is introduced into the impeller embedded in the water at the same time A filter replacement display device including a flow meter 105 configured to generate a pulse in accordance with a rotational speed (not shown), wherein a reference flow rate value and a sorting sequence of a constant supplied to the filter 103 are used. A first memory 106 for storing an effective constant amount for each filter 103 separately; The first memory 106 is connected so as to be communicable and the flow rate value calculated as a pulse signal of the flow meter 105 is accumulated in the second memory 107 to calculate a cumulative flow rate value, and the cumulative flow rate value is the first memory. If it is larger than the effective constant amount of each filter 103 previously stored in the 106, an exchange signal of the corresponding filter 103 is generated, but only when the calculated flow rate value is smaller than the reference flow rate previously stored in the first memory 106. A processing unit 109 for generating a filter 103 replacement signal; A warning unit 110 for informing a user of an exchange message of the filter 103 by using a predetermined signal according to a predetermined signal generated by the processing unit 109; It is achieved by a water purifier having a filter replacement display function, characterized in that it comprises a reset unit 108 for erasing and initializing the comparison value to date after the filter 103 is replaced.

Here, the processing unit 109; An analysis unit (109a) electrically connected to the flow meter (105) to analyze the pulse signal generated from the flow meter (105) to calculate flow rate values and flow rate values; The cumulative flow rate value accumulated in the second memory 107 is compared with the effective constant amount for each filter 103 of the first memory 106, and the current flow rate value calculated by the analysis unit 109a is the first memory 106. And a comparison unit 109b for generating a signal according to the comparison value in comparison with the reference flow rate value.

And, the notification means; At least one of a buzzer (not shown) that generates an audible warning sound to the user and an LED (not shown) 9 that visually indicate when to replace the filter 103 are preferable.

In addition, the notification means; Preferably, the analysis unit 109a further includes an LCD (not shown) indicating a cumulative flow rate value accumulated in the second memory 107 to indicate when to replace the filter 103.

The apparatus further includes a program input unit 111 configured to update an effective constant amount, a reference flow rate value, and a cumulative flow rate value of the second memory 107 of each filter 103 stored in the first memory 106. desirable.

Hereinafter, the operation according to the configuration of the present invention will be described with reference to FIGS. 1 to 2.

First, a substance that needs purification, such as foreign matter or residual chlorine, is first, second, third, and fourth filters 103a, 103b, 103c, and 103d through the inlet pipe 102 as shown in FIG. The plurality of filters 103 are introduced into the filter 103, and the flow meter 105 may be installed in the connecting pipe 104 between the filter 103 and the filter 103. ) May be provided.

Here, the flow meter 105 is a known impeller (not shown) is built, the pulse generator 113 (magnetic sensor) is installed to generate a pulse in accordance with the rotation of the impeller.

Therefore, the generated pulses are such that the analysis unit 109a of the processing unit 109 counts the number of pulses to calculate the flow rate that has passed through the flowmeter 105.

Since the signal generated from the pulse generator 113 is calculated as a flow rate value by the analysis unit 109a of the processing unit 109 and accumulated in the second memory 107, the filter 103 is currently present in the second memory 107. The cumulative flow rate value passed through) is stored.

In addition, the analysis unit 109a is capable of analyzing the flow rate of the raw water passing through the current flow meter 105 as well as the flow rate in analyzing the pulse, the number of pulses and pulses generated from the pulse generator 113 It is possible to calculate the flow rate by checking the time interval between pulses.

When the cumulative flow rate value and the flow rate value are calculated by the analysis unit 109a as described above, the comparison unit 109b of the processing unit 109 performs the effective constant amount and the accumulated flow rate for each filter 103 stored in the first memory 106. Compare the values.

For example, when the effective constant amounts of the first, second, third and fourth filters 103a, 103b, 103c and 103d are 1000cc, 1200cc, 1600cc and 2000cc, respectively, The analysis unit 109a analyzes the pulse generated by the pulse generator 113 to calculate the accumulated flow rate value and the flow rate value, and stores the accumulated flow rate value and the flow rate value in the second memory 107, and the comparison unit 109b stores the flow rate value in the first memory. It is checked whether the flow rate value is smaller than the reference flow rate value in comparison with the reference flow rate value in the memory 106.

Therefore, when the measured flow rate value is smaller than the reference flow rate value as described above, the user will be described later to replace the filter 103 in which the accumulated flow rate value and the effective constant amount and the accumulated flow rate value of each filter 103 are approximated. Notified by means.

In addition, if the measured cumulative flow rate value is larger than the effective constant amount for each filter 103, the corresponding filter 103 should be replaced. If the flow rate value is smaller than the reference flow rate value, the effective filter quantity reference filter 103 should be replaced. If not, the exchange message is notified to the user.

Therefore, the first first filter 103a needs to be replaced at a cumulative flow rate of about 1000 cc. However, since the pollution concentration of raw water varies depending on the user's use region, the first filter 103a may notify the user of the replacement message at 1000 cc or less.

When the cumulative flow rate value exceeds 1200 cc, the cumulative flow rate value exceeds the effective constant amount of the first and second filters 103a and 103b by the comparing unit 109b, and compares the flow rate value with the reference flow rate value. When the result value is the flow rate value is smaller than the reference flow rate value, the user is notified by the notification means of the exchange message of the first and second filters 103a and 103b.

In this way, it is possible to know that it is time to replace each of the first, second, third, and fourth filters 103a, 103b, 103c, and 103d based on the accumulated flow rate value. By comparing the flow rate values, it is possible to know the exact replacement timing of the filter 103.

After replacing the filter 103 to be exchanged as described above, the reset unit 108 is operated to clear the values compared so far in the comparator 109b and compare the next exchange time.

On the other hand, when the notification means to inform the user of the replacement time of the filter 103, the processing unit 109 according to the exchange time notification signal of the comparator 109b to the buzzer so that the user can know the exchange time audibly. The alarm signal may be transmitted by transmitting an electrical signal. On the other hand, the LED may be turned on or off by supplying power to the LED so that the user may visually know when to replace the filter 103. To ensure that

On the other hand, the above-mentioned notifying means displays the corresponding filter 103 to be exchanged with the accumulated flow rate value accumulated in the second memory 107 by the analyzing unit 109a to which LCD 103 to replace. To inform the user.

In addition, the filter 103 has a program input unit 111 so that the user can store the effective constant amount of the filter 103 used in the first memory 106 because the effective constant amount is different for each manufacturer. By directly updating and storing the effective constant amount for each filter 103, the compatibility with respect to the filter 103 for each manufacturer is improved.

As described above, the present invention detects the flow rate value of raw water passing through the flowmeter and compares it with the reference flow rate value to calculate the optimum filter replacement time, and also stores the effective constant amount for each filter among the plurality of filters. In addition, the cumulative flow rate value passed through the flowmeter can be compared with the effective constant amount of each filter so that the replacement time of the filter can be optimized individually.
