Accordingly, the hygiene and space efficiency of the water purifier can be increased.

The valve 260 is disposed between the water intake passage 220 and the water outlet 250 to open and close the passage between the water intake passage 220 and the water outlet 250. More specifically, the valve 260 is disposed between the water flow path 220 and the water outlet 250, connects the water flow path 220 and the water outlet 250 in the open state, and connects the water flow path 220 and the water outlet 250 in the closed state. The outlet unit 250 is disconnected. That is, when the valve 260 is opened, the fluid in the water intake passage 220 may flow toward the water outlet 250 and be discharged to the outside. On the other hand, when the valve 260 is closed, the fluid in the intake passage 220 cannot flow toward the water outlet 250, and flows toward the purified water generation module 100 through the drain passage 270.

The valve 260 may be disposed inside the housing 210 and coupled to the water outlet 250. As the valve 260 is disposed inside the housing 210, the length of the flow path between the valve 260 and the water outlet hole 252h is minimized, and the capacity of purified water remaining despite the opening of the drain flow path 270 is reduced. It can be minimized.

A drain valve (not shown) may be provided in at least one of the purified water generation module 100, the recovery flow path 150, the water discharge module 200, and the drain flow path 270. When the valve 260 is opened to discharge fluid, the drain valve (not shown) is closed to block fluid flow through the drain passage 270. When valve 260 is closed for draining, the drain valve (not shown) opens to allow fluid flow through drain flow path 270.

Additionally, the connecting member 265 is connected to the drain passage 270. In a state in which the valve 260 is closed, the fluid in the intake passage 220 may flow into the drainage passage 270 through the connection member 265.

The drain passage 270 drains the fluid present in the water intake passage 220 to the outside of the water outlet module 200 when the valve 260 is closed. The drain flow path 270 is a flow path for draining the flow rate provided through the water intake flow path 220 that is not discharged to the outside and needs to be drained toward the purified water generation module 100. The drain flow path 270 is connected to the recovery flow path 150. The remaining fluid in the water flow path 220 before water discharge may be drained toward the purified water generation module 100 through the drain flow path 270.

In addition, the interface unit 280 additionally provides an interface through which selection information for any one of the first integer, second integer, and third integer can be input when an activation request for the outlet unit 250 is input. , after a selection has been made for any one of the first integer, the second integer, and the third integer, an interface can be provided through which a request for extraction of the selected integer can be input. At this time, the interface unit 280 may provide an interface through which selection information and a water extraction request for one of the first integer, second integer, and third integer can be input simultaneously. For example, the interface unit 280 provides a touch screen-type interface, and activation requests, selection information, and water extraction requests may be input through touching icons, but are not limited thereto. For example, the water outlet module 200 may include a cup detection sensor (not shown), and the interface unit 280 may receive an activation request through detection of a cup monitoring sensor (not shown).

In an embodiment of the present invention, the interface unit 280 is coupled to the moving unit 230 to provide a manipulation interface and is displaced integrally with the moving unit 230. The interface unit 280 may be coupled to the second moving unit housing member 232 that partitions the front portion of the moving unit 230. For example, the interface unit 280 may provide a touch screen-type operating interface. Additionally, the interface unit 280 can display various types of information.

Below, the process of discharging water from a water purifier according to an embodiment of the present invention will be described in detail. Water extraction is accomplished by first inputting an activation request for the water outlet unit 250, and then inputting selection information and a water extraction request for any one of the first integer, second integer, and third integer. At this time, activation requests, selection information, and water extraction requests may be input through the interface unit 280.

Figure 10 is a diagram showing the flow of purified water when the valve of the water outlet module of the water purifier according to an embodiment of the present invention is closed.

Referring to FIG. 10, when a request for activation of the water outlet 250 is input, the valve 260 is closed and the fluid existing in the water flow path 220 is disconnected from the water flow path 220. is drained through the drain flow passage 270. To this end, the drain passage 270 may be opened by the aforementioned drain valve (not shown). Through this, the fluid remaining inside the water flow passage 220 before water discharge proceeds can be drained, and the problem of the remaining water being discharged at the beginning of water discharge and not satisfying the user's desired appropriate temperature can be solved. In this regard, as described above, the valve 260 may have a closed state as a default condition.

Meanwhile, when the fluid existing in the water intake flow path 220 is drained through the drain flow path 270, second purified water may be supplied to the water intake flow path 220 from the purified water generation module 100. That is, the second purified water may be filled in the flow path that becomes empty as the remaining fluid in the water flow path 220 is drained. As described above, the second purified water refers to cold water having a temperature lower than room temperature.

Figure 11 is a diagram showing the flow of purified water when the valve of the water outlet module of the water purifier according to an embodiment of the present invention is open.

Referring to FIG. 11, when selection information for the first purified water or the second purified water and a water discharge request are input after inputting the activation request, the valve 260 is opened and the fluid filled in the water flow path 220 is discharged into the water discharge portion 250. ) is released through. To this end, the drain passage 270 may be closed by the aforementioned drain valve (not shown). As described above, when an activation request is input, the remaining water in the water intake channel 220 is drained, and the second purified water is supplied into the water intake channel 220 to fill it. In this state, when selection information for the second purified water and a request for water extraction are input, water extraction can proceed immediately because the second purified water is already filled inside the water intake passage 220. Accordingly, the valve 260 is opened to discharge the second purified water inside the water intake passage 220, and then the second purified water is discharged from the second purified water generating unit 120 of the water purification generation module 100 toward the water intake passage 220. It is supplied additionally and released. Meanwhile, even when selection information for the first purified water and a request for water discharge are input after the activation request for the water outlet unit 250 is input, the valve 260 is opened and the second purified water inside the water flow passage 220 is preferentially discharged. do. In addition, first purified water is additionally supplied from the first purified water generator 110 of the purified water generation module 100 to the water intake passage 220 and discharged. The second purified water has a lower temperature than the first purified water, but the amount of fluid inside the water flow passage 220 is not large, and when a relatively large amount of the first purified water is discharged and mixed with the initially discharged second purified water, when the user drinks it The temperature of purified water is room temperature. In this way, according to the present invention, when selection information for the first or second purified water and a water discharge request are input after inputting the activation request, the valve 260 is immediately opened and the fluid filled in the water flow path 220 is discharged to the water outlet. By dispensing water through 250, the user can immediately receive the first or second purified water.

When a small amount of second purified water and a large amount of first purified water filled inside the water inlet flow passage 220 are mixed, the user recognizes it as room temperature purified water, but the small amount of first purified water and a large amount of first purified water filled inside the water inlet flow path 220 are mixed. 2 When purified water is mixed, the user perceives the temperature of the cold water as lukewarm. In consideration of this, the water purifier according to the embodiment of the present invention fills the water intake passage 220 with the second purified water in advance before discharging water, and discharges purified water at the temperature desired by the user.

Meanwhile, in an embodiment of the present invention, when selection information for the third purified water and a water discharge request are input after the activation request is input, the valve 260 is closed until the third purified water reaches a predetermined temperature. is maintained, and when the third purified water reaches a predetermined temperature, the valve 260 is opened and the third purified water is discharged through the water outlet 250. At this time, the third constant refers to hot water having a temperature higher than room temperature. As seen above, when an activation request is input, the remaining water in the water intake flow path 220 is drained, and the second purified water is supplied into the water water flow path 220 to fill it. In this state, if the valve 260 is immediately opened when the selection information for the third purified water and the water discharge request is input, the third purified water (hot water) of the user's desired temperature cannot be discharged. Therefore, the valve 260 remains closed until the third purified water supplied by the third purified water generator 130 of the purified water generation module 100 reaches a predetermined temperature. At this time, the fluid inside the water intake passage 220 may be drained through the drain passage 270 until the third purified water of a predetermined temperature is supplied. In addition, when the third purified water supplied by the third purified water generator 130 reaches a set predetermined temperature, the valve 260 is opened, water is discharged, and the user receives third purified water (hot water) at a predetermined temperature from the beginning of water discharge. ) can be provided.

In the water purifier according to an embodiment of the present invention, an activation request for the water outlet unit 250 is first input, and then selection information and a water discharge request for any one of the first integer, the second integer, and the third integer are additionally inputted. It is done by inputting. In this regard, in the water purifier according to an embodiment of the present invention, when an activation request is input, the moving part 230 is displaced from the first position to the second position, and the drain passage 270 is moved while the moving part 230 is being displaced. ) can be configured to allow drainage to proceed. In addition, the water purifier according to the embodiment of the present invention is configured to input selection information and a water discharge request for any one of the first purified water, the second purified water, and the third purified water while the moving unit 230 is displaced to the second position. It can be.

According to this configuration, in the process of displacement of the moving unit 230 after an activation request is input, that is, in the process of preparing for water extraction, the remaining water in the water flow passage 220 can be drained and the second water purifier can be newly filled. Additionally, if selection information for the first purified water or the second purified water and a water dispensing request are input while the moving unit 230 has completed displacement to the second position, water dispensing may proceed immediately. In other words, according to the present invention, when the final water discharge request is input, the remaining water inside the water flow passage 220 is already drained, and additional time consumption for draining the remaining water can be minimized. In other words, by using the time for the moving part 230 to displace as the time to drain the remaining water in the water flow passage 220, the time required to discharge the first or second purified water at the desired temperature is shortened and the water discharge efficiency is improved. This can be maximized.
