Description

Indicator of water purifier noting filter exchange}

The present invention relates to a filter replacement indicator of a water purifier that notifies the filter replacement time according to the usage amount of purified water in a water purifier which filters raw water by itself using a filter.

In general, a water purifier having a function of directly purifying raw water is installed in a structure in which a plurality of filters are arranged in a row, and then raw water passes through the plurality of filters in turn and is discharged to a water outlet formed by a one-touch cock or a valve.

In the prior art, in order to determine the replacement cycle of a plurality of filters built in the water purifier, regardless of the amount of water used, the replacement is performed uniformly according to the period of use. Increase or decrease the filter.

For example, four filters are equipped with a first-order sediment filter, a second-order post carbon filter, a third-order hollow fiber filter, and four fourth-order precarbon filters. In the case of the water purifier, the replacement cycle of each filter is set to about 6 months for the primary sediment filter and the secondary post carbon filter, and 12 for the third hollow fiber filter and the fourth primary carbon filter. It's set for about a month.

Reference numeral 1 denotes a main body of the water purifier, and a plurality of filters 2a, 2b, 2c, and 2d are built into the main body 1.

The filters are, for example, secondary, tertiary and quaternary filters 2b, 2c, and 2d based on the primary filter 2a to which the raw water supply tube 3 is connected. Is connected in series, and the purified water passing through the 4th order filter 2d is discharged to the water outlet 4 installed in the front of the main body 1.

In the above embodiment, the number of filters is set to four, but the filters may be installed in increments or decrements depending on the size and the amount of purified water used.

In addition, the filters in the above embodiments have different structures, and are generally composed of a sediment filter, a post carbon filter, a hollow fiber filter, a free carbon filter, and the like as in the prior art.

The body 1 is equipped with a flow rate detection unit 5, the flow rate detection unit 5 is connected to the fourth filter (2d) and the water outlet (4) on the purified water outflow tube 34 to discharge the purified water It is equipped to detect the purified water flow rate which flows out to the water extraction part 4 when it is attached.

The flow rate detection unit 5 has a water inlet port 51a and a water outlet port 51b connecting the purified water outlet tube 34 to both sides, and a space communicating with the water inlet port and the water outlet port while the upper portion is opened. In one direction by the flow rate of the purified water flowing into the inlet 51a, which is rotatably installed in the case 51 and the lower hinge 52 formed in the inner center of the case 51 and exits the outlet 51b. While rotating the impeller 53, the magnet 54 is fixedly attached to the upper end of the shaft 53a of the impeller 53 and rotates together with the impeller 53, and the upper part of the case 51 An upper hinge 53b fixedly installed at an upper end of the shaft 53a of the impeller 53 is rotatably installed, and is fixedly installed on an upper surface of the cover 55 and above one side of the magnet 54. In the magnet 54 each time It is composed of a magnetic sensor 56 for detecting the total number, the cover 55 as a bolt 58 in the state of sandwiching the packing (57) between the upper inner peripheral surface of the case 51 and the outer peripheral surface of the cover 55 Fixed to the case 51 so that the purified water flowing into the case 51 through the water inlet 51a is not leaked, and the magnetic sensor 56 installed on one side of the cover 55 is covered. The protection plate 59 which gives and protects is attached.

The magnetic sensor 56 of the flow rate detection unit 5 configured as described above is connected by an electric wire 7 so as to send an electric signal to the flow rate display and the filter exchange display unit 6 attached to the front surface of the main body 1.

The flow rate display and the filter change display unit 6 receive a signal output from the CPU 61 which automatically calculates an electrical signal input from the magnetic sensor 56 and displays a liquid crystal display digitally. And a filter replacement display panel 63 provided with a plurality of lamps 63a, 63b, 63c, and 63d formed of the same number of LEDs or LCDs as the respective filters built into the main body 1.

In addition, the flow rate display and the filter replacement display unit 6 cause the liquid crystal panel 62 to be exposed to the front surface of the main body 1, and each lamp of the filter replacement display panel 63 protrudes to the front side. It is fixedly installed inside.

The liquid crystal panel 62 has a function of displaying the used purified water flow rate as a letter and indicating the flow rate of the purified water. When the purified water does not flow out, the liquid crystal display panel 62 has a function of a clock and also informs to replace the battery. It also has a function, and furthermore, when the purified water is leaked, the arrow indicators indicating the leaked state of the purified water are sequentially turned on so that the user can visually check the leaked state of the purified water.

The operation of the present invention configured as described above will be described.

When the raw water supply tube 3 is connected to the primary filter 2a embedded in the main body 1 and then the raw water is supplied, the raw water passes through the first to fourth filter 2a, 2b, 2c, and 2d in order. Each filter, each connecting tube (31.32., 33) and the purified water outflow tube 34 is filled with raw water or purified water, in this state open the water outlet (4) installed on the front of the body (1) In operation, the purified water passing through the fourth filter 2d passes through the purified water outlet tube 34 and the flow rate detection unit 5 installed therein, and then flows out to the water extraction unit 4, where the fourth filter 2d is used. When passing through the inlet 51a of the case 51 of the flow rate detection unit 5 and flows out to the outlet 51b, the impeller 53 mounted inside the case 51 is rotated. The impeller 53 rotates quickly or slowly depending on the flow rate of the purified water flowing out to the water outlet 4. That is, when a large amount of purified water flows out to the water outlet 4, the impeller 53 rotates quickly. On the contrary, when a small amount of purified water flows out to the water outlet 4, the impeller 53 rotates slowly. Thus, the flow rate of the purified water flowing out to the water outlet 4 and the rotation speed of the impeller 53 are in a state directly proportional to each other.

When the impeller 53 is rotated as the purified water flows out to the water extraction unit 4 as described above, the magnet 54 installed while wrapping the upper end of the shaft 53a is also rotated together. ) Is divided into the S pole and the N pole, while the magnetic sensor 56 fixedly installed above one side of the magnet 54 detects that the polarity of the magnet 54 alternately changes and electrically transmits the signal. It has a function to send to the CPU 61 of the flow rate display and the filter replacement display part 6.

Therefore, the magnetic sensor 56 accurately detects the rotational speed of the magnet 54 that rotates together with the impeller 53, and simultaneously uses the detected rotational speed as an electrical signal of the flow rate display and the filter replacement display unit 6. The CPU 61 transmits the signal input from the magnetic sensor 56 electronically to display the flow rate of the purified water on the liquid crystal panel 62 in digital characters. It is possible to visually check the purified water consumption displayed on the display panel 62 in digital characters.

On the other hand, each of the plurality of lamps 63a, 63b, 63c, and 63d formed on the filter replacement display plate 63 of the flow rate display and the filter replacement display unit 6 uses the primary filters 2a to the fourth filter 2d. When the life reaches the measured value, it will light up sequentially to indicate when it is time to replace the filter.

For example, the primary and secondary filters 2a and 2b each have a life expectancy of 2000 liters, and the tertiary and quaternary filters 2c and 2d each assume that the measured lifespan is 4000 liters, respectively. Referring to the flow rate display indicating the replacement time of the filter and the operating state of the filter replacement display unit 6, first, when the purified water flowed out to the water outlet unit 4 reaches 2000 liters, the liquid crystal panel 62 displays digital characters. The lamps 63 and 63b indicating the replacement timing of the primary and secondary filters 2a and 2b of the four lamps displayed at 2000 liters and simultaneously formed on the filter replacement display panel 63 are turned on. Therefore, the user checks the lamps 63a and 63b that are turned on in the filter replacement display panel 63 and replaces the primary and secondary filters 2a and 2b, and the primary and secondary filters 2a and 2b. After replacement of the liquid crystal display, press the receptor button (not shown) mounted on the flow rate display and the filter replacement display unit 6, thereby turning off the lamps 63a and 63b which were previously turned on and simultaneously the digital display of the liquid crystal display panel 62. The character is also deleted, and the water consumption is displayed again from " 0 ", while the CPU 61 of the flow rate display and the filter replacement display unit 6 indicates the timing of replacing the primary and secondary filters 2a and 2b. When the water consumption (2000 liters) is stored and the purified water usage reaches 2000 liters, the lamps 63a and 63b for notifying the replacement of the primary and secondary filters 2a and 2b are turned on. And lamps 63c and 63d indicating when to replace the 3rd and 4th filters 2c and 2d. As to allow the exchange of all of the first through the fourth filter to the correct replacement time.

According to the present invention as described above, the liquid crystal display panel for installing the flow rate detection unit for detecting the purified water flow rate in the purified water outflow tube for distilling the purified water to the water outlet of the water purifier and receiving the signal detected by the flow rate detection unit and displayed in digital characters and each filter The filter replacement display board is equipped with a lamp to inform you of the replacement time on the front of the main body.It is possible to replace each filter according to the service life of the water purifier with a built-in filter. By knowing the timing individually, you can expect the effect of accurately measuring the lifespan of each filter so that it can be exchanged in a timely manner, contributing to your health by conserving resources and allowing you to use purified water with confidence. It is a useful invention that provides advantages.
