Description

Filter change notification device of water purifier

The present invention relates to a filter replacement notification device for a water purifier, and more particularly, a water purifier is used as a replacement time of each filter after calculating a life time according to the characteristics of each filter for removing foreign substances contained in water supplied to the water purifier. The present invention relates to a filter change notification device for a water purifier, which allows a user who uses the water purifier to always receive clean water.

In general, the water purifier is provided with a cold water tank and a hot water tank each having a temperature sensor installed therein, each of the first filter to sterilize after removing the foreign substances contained in the raw water sequentially in the passage for supplying the raw water to the hot water tank and the cold water tank And a membrane filter, a fourth filter and a fifth filter, raw water sterilized through the fifth filter flows into the hot water tank and the cold water tank by the fourth solenoid valve and the third solenoid valve, and is caught by the membrane filter. The concentrated water is configured to be discharged to the outside of the water purifier by the second solenoid valve.

In addition, when the water stored in the hot water tank and the cold water tank passes for a predetermined time (4-5 hours), the sixth solenoid valve and the seventh solenoid valve are introduced into the drip tank, and the water introduced into the drip tank is connected to the third pump. It is configured to be discharged to the outside of the water purifier through.

Here, the conventional filter is connected to a microprocessor set to the purified water (approximately 4300 hours = about 6 months) when the power is applied, the power supply applied to the filter to the purified water (approximately 4300 hours = about 6 months) The lamp or alarm that is activated when is exceeded is connected.

The conventional microprocessor uses a calculator to operate the power-on time of each filter, and when a filter water purification time (4300 hours = approximately 6 months) elapses, a lamp or a warning lamp is activated to inform the user of the water purifier that it is time to replace each filter. have.

However, such a conventional filter replacement method uses a predetermined time (about 4300 hours = about 6 months) calculated by a laboratory of each product, and then replaces the filter and uses a water purifier, so that environmental conditions (quality of water and consumer In the case where the water purification capacity of the water purifier is poor, the filter water is quickly lost, but each filter is used as much as the time entered into the microprocessor. In addition to receiving raw water as it is, as well as good environmental conditions, the lamp or warning lamp is activated when the time entered into the microprocessor passes even though the water purification capacity of the filter remains. There was a problem that wastes unnecessary resources by performing the replacement of.

It is an object of the present invention to solve the problems as described above, the degree of water quality and water purification capacity (compared to the level of water level compared to the use time of the initial pump) during the water level after three times of initial operation (consumer daily Water Purification: Check the 1al / 1 day), the environment sensing device with the data measured for 3 times, the power sensing unit to detect whether the power is supplied, and the operating cycle and lifespan of each filter according to the operation period of the pump It checks the life time according to the filter life cycle selection device and the value calculated for each filter and informs the filter when the life time is completed 42 hours before the life time and when the filter is changed through the color and buzzer of the lamp. By connecting the filter change notification device to the microprocessor, the water quality of raw water flowing into the water purifier, the frequency of using the water purifier, and the amount of purified water Ink stone as a foundation will tell time to replace the proper time, and for users who use the water purifier provides filter change notification system that allows you to use a water purifier water purifier going to replace each filter to the correct time.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

In the filter change notification device of the water purifier of the present invention, as shown in FIG. 2, the degree of water quality and the water purification capacity (comparison of the level of water with respect to the service time of the initial pump) during the three times of water level after initial operation are used. Environmental sensing device 10 to check (consumer daily water consumption: 1al / day basis) for three times, power detection unit 20 for detecting the presence or absence of power supply, and use cycle for each filter And the filter life cycle selection device 40 whose life span is equal to the pump operation period, and checks the life time according to the value calculated for each filter to inform the end of the life time of the filter 42 hours before the life time, Through the color and the buzzer of the filter replacement notification device for notifying the exchange time of the filter 50 is connected to the microprocessor 30 as a technical feature in its technical configuration.

On the other hand, the microprocessor 30 is to be used while adjusting the life time of each filter to the maximum (Min) average (AVG) according to the water quality, the water purification capacity and the frequency of use of the raw water flowing into the water purifier. It is preferable to install the key input 60.

As shown in FIG. 2 and FIG. 3, the present invention configured as described above includes a power detection unit 20 for calculating the life of each filter through the frequency of use of the pump from the time when the input for power supply is turned on. The water quality and water purification capacity (compared to the level of water compared to the initial pump usage time) during the three levels of water level after initial operation are detected by the customer. Checked and measured three times the data is input to the microprocessor through the environmental sensor 10, the filter life cycle selection device 40 is operated by the life cycle and life of each filter by the value input to the microprocessor 42 hours before the end of the life of the filter is completed, the filter replacement notification device 50 informs the end of the life time, and when the life time is completed through the color of the lamp and the buzzer It will give us the time.

On the other hand, the filter life time of the filter is determined by the user using the water purifier by using the key input 60, the maximum, minimum, average.

Therefore, in the present invention, the microprocessor performs a calculation according to the water quality of the raw water flowing into the water purifier, the water purification capacity of each filter, and the frequency of use, and checks the life time, and then replaces the filter through the filter replacement notification device 50. By making it easy for the user using the water purifier to replace each filter installed in the water purifier at an appropriate exchange time, the user using the water purifier always receives clean purified water, as well as the water purification function. By not replacing this remaining filter, there is an effect that waste of unnecessary resources is prevented.

As described above, according to the present invention, by changing each filter installed in the water purifier at an appropriate replacement time, the user using the water purifier is always supplied with purified water, as well as preventing unnecessary exchange of filters. This wasteful invention is a very useful invention to prevent it from happening.
