[0041] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0042] FIG. 1 is a drawing schematically illustrating a water purification system connectable to a water supply according to one embodiment of the present disclosure.

[0043] Referring to FIG. 1, a water purification system (10) (hereinafter, “water purification system”) connectable to a water supply according to one embodiment may include a direct water module (11), a water purification module (12), and a lever (not shown). However, in some embodiments, the water purification system (10) may include fewer or more components than the components shown in FIG. 1.

[0044] The water purification system (10) can operate the water purification module (11) when in the water purification mode, and the water purification module (12) when in the water purification mode. The change between the water purification mode and the water purification mode can be made through a lever (not shown).

[0045] A lever (not shown) is provided at a specific location of the water module (11) so that the direction can be manipulated (changed). However, the invention is not limited thereto, and the lever (not shown) may also be provided at a specific location of the water module (12).

[0046] Specifically, when the lever (not shown) is switched from a first direction to a second direction (e.g., from left to right), it can be set to a straight mode. When the lever (not shown) is switched from a second direction to a first direction (e.g., from right to left), it can be set to a constant mode.

[0047] When in direct mode, the direct water module (11) can directly discharge water (i.e., direct water) flowing in from the water supply through the outlet.

[0048] When in the purification mode, the purification module (12) can introduce water (i.e., direct water) from a water source through the direct water module (11), undergo a purification process, and then discharge purified water (i.e., purified water) through the outlet.

[0049] That is, the direct water module (11) and the water purification module (12) are connected, so that the water purification module (12) can receive direct water (tap water) from the direct water module (11).

[0050] The water purification module (12) generates its own power through the inflowing water (i.e., direct water) when in the water purification mode, and components within the water purification module (12) can be operated by the induced power generated through the self-generation.

[0051] Since the communication module included in the water purification module (12) operates with the induced power generated when in water purification mode, the water purification module (12) can communicate with the user terminal (20) only when in water purification mode.

[0052] Hereinafter, with reference to FIGS. 2a and 2b, the change in operation mode between the direct mode and the purified mode and the flow of water in each mode will be described.

[0053] FIG. 2A and FIG. 2B are drawings for explaining a direct mode and an integer mode according to one embodiment of the present disclosure.

[0054] The direct module (11) may include a first inlet (11-1), a first outlet (11-2), and a second outlet (11-3), and the purification module (12) may include a second inlet (12-1) and a third outlet (12-2).

[0055] Referring to FIG. 2a, when the water purification system (10) is set to the direct mode by a lever (not shown), the first inlet (11-1) and the first outlet (11-2) may be open, and the second outlet (11-3), the second inlet (12-1), and the third outlet (12-2) may be blocked.

[0056] At this time, the first inlet (11-1) and the third outlet (12-2) may always be open regardless of the operating mode.

[0057] The direct module (11) can discharge water introduced from the first inlet (11-1) connected to the water supply through the first outlet (11-2).

[0058] At this time, the water flowing out through the first outlet (11-2) may be direct water (tap water).

[0059] Referring to FIG. 2b, when the water purification system (10) is set to the water purification mode by a lever (not shown), the first outlet (11-2) may be blocked, and the first inlet (11-1), the second outlet (11-3), the second inlet (12-1), and the third outlet (12-2) may be open.

[0060] At this time, the first inlet (11-1) and the third outlet (12-2) may always be open regardless of the operating mode.

[0061] The water purification module (12) can introduce water into the direct water module (11) through the first inlet (11-1) connected to the water supply, through the second inlet (12-1) connected to the second outlet (11-3) included in the direct water module (11), and can discharge water introduced through the second inlet (12-1) through the third outlet (12-2).

[0062] At this time, the water flowing out through the third outlet (12-2) may be purified water.

[0063] The second outlet (11-3) and the second inlet (12-1) may be connected in a contacting manner, or may be connected in a manner spaced apart from each other by a certain distance.

[0064] Hereinafter, the integer module (12) will be described with reference to FIGS. 3 to 6.

[0065] FIG. 3 is a block diagram of a water purification module according to one embodiment of the present disclosure.

[0066] FIG. 4 is a drawing for explaining the positional relationship between a self-generator and a filter according to one embodiment of the present disclosure.

[0067] FIG. 5 is a drawing for explaining an operation timeline of a water purification module in a water purification mode according to one embodiment of the present disclosure.

[0068] FIG. 6 is a drawing for explaining the positional relationship between a self-generator and a sensor and the positional relationship between a filter and a sensor according to one embodiment of the present disclosure.

[0069] Referring to FIG. 3, the water purification module (12) may include a euro (not shown), a self-generator (121), a sensor unit (122), a filter (123), a display (124), a Bluetooth module (125), and a control unit (126). However, in some embodiments, the water purification module (12) may include fewer or more components than the components shown in FIG. 3.

[0070] A flow path (not shown) may be a water passage connecting a second inlet (12-1) and a third outlet (12-2). Water may be purified by passing through a filter (123) as it passes through the flow path.

[0071] The self-generator (121) is placed on a euro (not shown) and can generate induced power by the flow of water flowing in while in the purification mode.

[0072] The sensor unit (122) may include one or more sensors that operate only in the constant mode by inductive power.

[0073] The filter (123) is placed in the euro (not shown) and can filter the water flowing in while in the purification mode.

[0074] The display (124) can be operated by the induced power generated only when in the constant mode to display the status of the filter. That is, the display (124) can be operated only when in the constant mode by the induced power.

[0075] The Bluetooth module (125) can be connected to the user terminal (20) by operating with the induced power generated only when in the constant mode. That is, the Bluetooth module (125) can be operated only when in the constant mode by the induced power.

[0076] The communication module of the present disclosure is not limited to a Bluetooth module (125), and various wired communication modules, wireless communication modules, short-range communication modules, location information modules, etc. may be applied.

[0077] The control unit (126) can control the operation of components included in the water purification module (12) by operating only when the water purification mode is activated by inductive power.

[0078] The control unit (126) can perform operations using a memory that stores data for an algorithm for controlling the operation of components within the present integer module (12) or a program that reproduces the algorithm, and data stored in the memory (not shown). In this case, the memory (not shown) and the control unit (126) may be implemented as separate chips. Alternatively, the memory (not shown) and the control unit (126) may be implemented as a single chip.

[0079] In addition, the control unit (126) can control any one or a combination of the components discussed above to implement various embodiments according to the present disclosure described in FIGS. 3 to 6 on the water purification module (12).

[0080] That is, the water purification module (12) can start the operation of the remaining components by the induced power generated by the self-generator (121). To this end, the self-generator (121) must be placed first on the flow path (not shown) (i.e., it must be placed at the closest location to the second inlet (12-1)).

[0081] Here, induced power can be generated by rotating the rotary blade with the flow of water (tap water) provided from the direct current module (11).

[0082] In an embodiment, when the second outlet (11-3) and the second inlet (12-1) are connected at a certain distance apart, the distance between them can be set based on a preset reference power.

[0083] Specifically, the greater the reference power, the greater the distance between the two can be set. The greater the reference power, the more rotary blades are required for power generation, and the greater the distance between the two can be set to ensure that multiple rotary blades are spaced at preset intervals.

[0084] Referring to FIG. 4, on the path connecting the second inlet (12-1) connected to the direct current module (more specifically, the second outlet (11-3)) to the third outlet (12-2) that discharges purified water, the self-generator (121) can be positioned closer to the second inlet (12-1) than to the filter (123).

[0085] Referring to FIG. 5, when set to the constant mode, direct water flows into the purification module (12), and the self-generator (121) starts to operate using the introduced direct water, and when induced power is generated by the self-generator (121), the sensor unit (122), the display (124), the Bluetooth module (125), and the control unit (126) can all start to operate.

[0086] The sensor unit (122) of the present disclosure may include a first water quality sensor (122-1) disposed on one side of the flow path and operated by inductive power generated only when in the purification mode, and a second water quality sensor (122-2) disposed on the other side of the flow path and operated by inductive power generated only when in the purification mode.

[0087] The first water quality sensor (122-1) can measure the first characteristic of water before passing through the filter (123), and the second water quality sensor (122-2) can measure the first characteristic of water purified through the filter (123).

[0088] Here, the first property of water may be the total dissolved solids content of the water.

[0089] The control unit (126) can determine whether to replace the filter (123) based on the measurement values ​​of the first water quality sensor (122-1) and the second water quality sensor (122-2).

[0090] The control unit (126) can determine whether the filter needs to be replaced based on the difference between the total dissolved solids measurement value of the first water quality sensor (122-1) on one side and the total dissolved solids measurement value of the second water quality sensor (122-2) on the other side.

[0091] The sensor unit (122) of the present disclosure may further include a third water quality sensor (12-3) disposed on the other side of the euro and operated by induced power generated only when in the purification mode.

[0092] The third water quality sensor (12-3) can measure the second characteristic of water purified through the filter (123).

[0093] Here, the second characteristic of water may be its turbidity.

[0094] The control unit (126) can determine whether purified water is suitable for drinking based on the measurement values ​​of the third water quality sensor (12-3). By including sensors for determining whether the filter is functioning normally at the rear end of the flow path and sensors for measuring other characteristics, it is possible to determine whether filtered water is suitable for drinking separately from determining whether the filter is functioning normally.

[0095] Referring to FIG. 6, the first water quality sensor (122-1) may be positioned in front of the filter (123) on the euro, and the second water quality sensor (122-2) and the third water quality sensor (12-3) may be positioned in the rear of the filter (123). Through this positional relationship, the first water quality sensor (122-1) can measure the first characteristic of water before being filtered, and the second water quality sensor (122-2) and the third water quality sensor (12-3) can measure the first characteristic and the second characteristic of water after being filtered, respectively.

[0096] In addition, although FIG. 6 illustrates that the first water quality sensor (122-1) is positioned between the self-generator (121) and the filter (123) on the euro, the present invention is not limited thereto, and the first water quality sensor (122-1) may be positioned in front of the self-generator (121) or may be positioned in parallel with the self-generator (121).

[0097] Additionally, the Bluetooth module (125) and control unit (126) not shown in FIG. 6 may be placed anywhere within the euro, or may be attached outside the euro.

[0098] Additionally, a display (124) not shown in FIG. 6 may be exposed outside the integer module (12) to convey information to the user.

[0099] The display (124) can display information on the water supply status, water quality status, and whether the filter needs to be replaced, and can display information on whether the filter needs to be replaced based on color, pattern, etc.

[0100] The control unit (126) can control the display (124) to display different colors depending on the status of the filter (123) or whether it is drinkable.

[0101] For example, when filter replacement is not required, the color of the display (124) may be set to glow blue, and when filter replacement is required, the color of the display (124) may be set to glow red.

[0102] As another example, if the purified water is potable, the color of the display (124) can be set to glow white, and if the purified water is not potable, the color of the display (124) can be set to glow yellow.

[0103] The control unit (126) can determine whether the filter needs to be replaced by using the difference between the measured values ​​of the first water quality sensor (122-1) and the second water quality sensor (122-2). Specifically, if the difference between the two measured values ​​is within a predetermined value, it can be determined that the filter is not functioning properly and thus needs to be replaced.

[0104] Additionally, if the measurement value of the second water quality sensor (122-3) is higher than a predetermined value, the control unit (126) can determine that the purified water passing through the filter (123) is unsuitable for drinking.

[0105] When the control unit (126) is connected to the user terminal (20) via the Bluetooth module (125), it can transmit a message informing the user terminal (20) of the current status information of the filter (123). The user can know when to replace the filter through the transmitted message.

[0106] According to an embodiment, the status information of the filter (123) provided to the user terminal (20) can be accumulated and managed, and the control unit (126) can analyze the pattern of the period in which the function of the filter (123) is reduced through the accumulated status information, and can predict the next replacement time through the analyzed pattern.

[0107] The control unit (126) can transmit a message to the user terminal (20) notifying the next predicted replacement time.

[0108] A user terminal (20) may refer to a terminal of a customer using the water purification management service of the present disclosure, or a device of an administrator providing the water purification management service. Customers can install a customer service application (program) on their user terminal (20) to use the service in the form of an online web or app. Administrators can install an administrator service application (program) on their user terminal (20) to manage customers.

[0109] The user terminal (20) may be applied with an information processing means such as a computer, and may include a processor such as a control unit, a photographing means such as a camera, an input / output means including a touch screen, and may mean any device with a communication function. In other words, any device such as a smartphone, tablet, PDA, laptop, or desktop may be applied.

[0110] Hereinafter, the method performed by the water purification system (10) will be described with reference to FIG. 7.

[0111] FIG. 7 is a flowchart of a water purification method performed by a water purification system according to one embodiment of the present disclosure.

[0112] Referring to Fig. 7, when the direct water module (11) of the water purification system (10) is set to the direct water mode, water (tap water) flowing in from the first inlet (11-1) connected to the water supply can be discharged through the first outlet (11-2) (S710).

[0113] It is possible to change from the straight water mode to the purified water mode by a lever included in the straight water module (11) or the purified water module (12) of the purified water system (10) (S720).

[0114] When set to the purification mode by the lever, the purification module (12) can introduce the water (tap water) through the second inlet (12-1) connected to the second outlet (11-3) (S730). Here, the second outlet (11-3) may be included in the direct water module (11), and the second inlet (12-1) may be included in the purification module (12).

[0115] The water purification module (12) can purify (filter) water (tap water) introduced through the second inlet (12-1) using a filter (123) (S740).

[0116] The water purification module (12) can discharge purified water (purified water) through the filter (123) through the third outlet (12-2) (S750).

[0117] The contents of steps S710 to S750 are the same as those described above with reference to FIGS. 1 to 6, so detailed descriptions are omitted.

[0118] In addition, although the steps of FIG. 7 are described as being performed by a water purification system (10), the subject performing the steps of FIG. 7 may be a water purification device connected to a water supply. That is, the steps of FIG. 7 may be performed by a water purification device including a lever, a direct-flow module (11), and a water purification module (12).

[0119] At this time, the water purification module (12) of the water purification device may include a flow path (not shown), a self-generator (121), a sensor unit (122), a filter (123), a display (124), a Bluetooth module (125), and a control unit (126) as described above. However, depending on the embodiment, the display (124), the Bluetooth module (125), and the control unit (126) may be included in the water purification device as separate components from the water purification module (12).

[0120] Although FIG. 7 describes the steps as being executed sequentially, this is merely an example of the technical idea of ​​the present embodiment, and a person having ordinary knowledge in the technical field to which the present embodiment belongs can modify and apply various modifications and variations by changing the order described in FIG. 7 or executing them in parallel without departing from the essential characteristics of the present embodiment, and therefore FIG. 7 is not limited to a chronological order.

[0121] Meanwhile, in the above description, the steps described in FIG. 7 may be further divided into additional steps or combined into fewer steps, depending on the implementation example of the present disclosure. Furthermore, some steps may be omitted as needed, and the order of the steps may be changed.
