A water purifier having a filter exchanging time indication equipment

The present invention relates to a water purifier having a filter replacement display function, and in particular, a casing forming an appearance of a predetermined shape; At least one filter connected to the inlet pipe to allow the constant to be introduced into the casing and the inlet pipe to purify the constant, and a connection pipe and the inlet pipe connected between the filters to provide a constant A water purifier having a filter change indication function including a flow meter which allows a passage to be generated and generates a pulse according to the rotational speed of the impeller that is rotated when the built-in constant pass is passed. Even the last consumer without a filter can know the optimal replacement time of the filter to prevent the waste of resources in advance, and the filter can always be replaced at the optimum time even if the degree of pollution of the constant and the effective constant of the filter differ by manufacturer. Not only that, but also that the purified water can be used in an optimal state, It provides a water purifier having a filter function that allows exchange display.

In general, a water purifier allows a user to drink water introduced through an inlet pipe by filtering a plurality of filters, and a method using a timer is used as a method for informing the replacement time of the plurality of filters. The method of using the timer is to display the use time of the filter in the existing water purifier as a timer, so that the life of the filter can be known in advance. Even when not in use, it has been pointed out that when a certain time elapses, the timer displays the replacement time, thereby deteriorating the reliability of the filter replacement.

In the improved conventional filter replacement method that solves the above problems, the effective water purification amount is determined according to the filter filtration capacity of the first filter and the raw water filtration amount of the first filter is checked. Calculated by the filter, and when the raw water more than the effective water is filtered, the filter is replaced. Accordingly, the second filter, the third filter, and the fourth filter also set a certain amount of effective constant water, and if the effective water quantity is exceeded, the user can change the filter time. I let them know.

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. By alerting consumers to the timing of filter replacement compared to the effective water flow rate and flow rate value, the filter can be replaced at the optimum time, thus saving the economic waste and resources, as well as the filtered water by the filter that guarantees the optimal filtration capacity. Its purpose is to contribute to the promotion of national health by making it drinkable.

The above object, according to the present invention, the casing 101 to form an appearance of a predetermined shape; An inlet pipe 102 for allowing a constant to be introduced into the casing 101 and at least one filter 103 connected to the inlet pipe 102 to purify the constant, and a connection between the filter 103. Flow meter is installed in any one of the connecting pipe 104 and the inlet pipe 102 to pass the constant and at the same time to generate a pulse according to the rotational speed of the impeller rotated when the built-in constant passing ( A water purifier having a filter 103 replacement display function comprising a filter 103, comprising: a reference flow rate value of a constant supplied to the filter 103 and an effective constant amount for each filter 103 based on the sorting order; One memory 106; The first memory 106 is connected so as to be communicable and the flow rate value calculated as the pulse signal of the flow meter 105 is accumulated in the second memory 107 to calculate the accumulated flow rate value, and the accumulated 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; The filter 103 is achieved by a water purifier having an exchange display function, characterized in that it comprises a reset unit 108 for erasing and initializing the comparison value to date after the filter 103 has been 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 the buzzer 120 that generates an audible warning sound to the user and the LED 121 that visually indicates an exchange time of the filter 103 may be used.

In addition, the notification means; The LCD 123 may further include an LCD (123) indicating the cumulative flow rate value accumulated in the second memory 107 by the analyzing unit 109a 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 3.

First, as shown in FIG. 1, tap water is supplied to a plurality of filters 103 such as first, second, third, and fourth filters 103a, 103b, 103c, and 103d through the inlet pipe 102. As it flows in, the flow meter 105 may be installed in the connecting pipe 104 between the filter 103 and the filter 103, and the flow meter 105 is installed in the inlet pipe 102 or the outlet pipe 112. It may be.

Here, the flow meter 105 is known, and only its appearance is shown in FIG. 1, and to explain schematically, an impeller is built in, and an impeller (not shown) is installed with a pulse generator 114 (magnetic sensor). Pulse is generated by the rotation of.

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 114 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 has been applied to the second memory 107 so far. 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 114 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 1000L, 1200L, 1600L and 2000L, respectively, The analysis unit 109a analyzes the pulse generated by the pulse generator 114 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. 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 cumulative 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. However, if the flow rate value is larger than the reference flow rate value, the filter 103 is not replaced. Do not notify the user of the message.

Therefore, the first first filter 103a should be replaced with a cumulative flow rate value of about 1000L, but since the pollution concentration of raw water varies according to the user's use area, an exchange message may be notified to the user below 1000L. You can also notify the user of the message.

When the cumulative flow rate value exceeds 1200L, 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 cumulative 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 replaced 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 is 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 is a buzzer (buzzer) so that the user can know the exchange time audibly ( 120 to transmit a signal so that a warning sound can be generated, and on the other hand, the LED is supplied with power so that the user visually knows when to replace the filter 103. To make it flash or light up.

On the other hand, the above notification 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 on the LCD 123 to exchange any filter 103. Let the user know what to do.

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 this way, the cumulative flow rate value passed through the flowmeter is compared with the effective constant amount of each filter, so that the filter replacement time can be optimized individually. Has the effect of
