In addition, a sterilizing water valve 44 may be installed in the sterilizing water pipe 34 to control the flow of water in the sterilizing water pipe 34 .

In addition, a flow control valve 37 for controlling the amount of water flowing into the hot water tank 130 may be installed in the hot water pipe 33 . In addition, a safety valve 51 for discharging steam may be installed in the hot water tank 130 .

On the other hand, when the flow rate sensor 36 is provided as described above, the amount of water supplied to the cold water tank 140 and the hot water tank 130 can be sensed, and the cold water tank 140 and hot water can be measured using the flow rate information. The output supplied to the tank 130 can be adjusted.

In addition, when the flow control valve 37 is provided, the amount of water supplied to the hot water tank 130 can be adjusted, so that hot water at a desired temperature can be immediately generated by the user.

In addition, the purified water pipe 31, the cold water pipe 32, the hot water pipe 33, and the sterilizing water pipe 34 each have a water purification valve 41, a cold water valve 42, a hot water valve 43, sterilization When the water valve 44 is provided, the flow of water supplied to the cold water tank 140, the hot water tank 130, and the sterilizing water module 150 can be controlled. In addition, the cold water valve 42, the hot water valve 43, and the sterilizing water valve 44 are opened only when it is necessary to generate cold water, hot water, or sterilizing water, so that the cold water tank 140, the hot water tank 130, and the sterilizing water module ( 150) to supply water. In addition, the water purification valve 41 is opened only when purified water is required, and thus purified water can be supplied to the water outlet 200 .

The water outlet 200 supplies purified water, cold water, hot water, and sterilized water supplied from the purified water pipe 31, the cold water pipe 32, the hot water pipe 33, and the sterilized water pipe 34 to the user. Includes water outlet nozzles 210 and 220 of. The plurality of water outlet nozzles 210 and 220 may extend horizontally from the body 230 extending vertically to be exposed to the upper side of the sink 10 .

The water extraction nozzles 210 and 220 may include a first water extraction nozzle 210 through which purified water, cold water, and hot water are discharged, and a second water extraction nozzle 220 through which sterilized water is discharged.

For example, the first water outlet nozzle 210 and the second water outlet nozzle 220 may be spaced apart from each other in the vertical direction. At this time, the first water outlet nozzle 210 may be disposed on the upper side, and the second water outlet nozzle 220 may be disposed on the lower side.

Therefore, as the sterilized water discharged from the second water outlet nozzle 220 falls on the first water outlet nozzle 210 through which purified water, cold water, and hot water are dispensed, the first water outlet nozzle 210 is contaminated by the sterilizing water. can be prevented. In addition, since the first water outlet nozzle 210 for dispensing cold, hot, and purified water, which is relatively frequently used, is disposed on the upper side, it is easy for users to access, operate, and dispense water. In addition, the second water outlet nozzle 220, which is used relatively little, is disposed below the first water outlet nozzle 210, can be concealed, and is difficult to access compared to the first water outlet nozzle 210, so sterilizing water is accidentally released In this way, accidents can be prevented.

As another example, the first water outlet nozzle 210 and the second water outlet nozzle 220 may be spaced apart in a horizontal direction.

The first water outlet nozzle 210 and the second water outlet nozzle 220 may be rotatably mounted with respect to the body 230 . The first water outlet nozzle 210 and the second water outlet nozzle 220 may rotate independently.

On the other hand, purified water and cold water flowing along the purified water pipe 31 and the cold water pipe 32 are joined in one first common pipe 38, and through the first common pipe 38, toward the water outlet 200. can be supplied. Therefore, purified water, cold water, and hot water flowing through the first common pipe 38 and the hot water pipe 33 are supplied to the user through the first water outlet nozzle 210 .

In addition, the hot water pipe 33 may also join the first common pipe 38 . Also, the second common pipe 39 may connect the water outlet 200 from a point where the hot water pipe 33 and the first common pipe 38 join. In this case, purified water, cold water, and hot water flowing through the second common pipe 39 may be supplied to the user through the first water outlet nozzle 210 .

In addition, the sterilizing water generated by the sterilizing water module 150 may flow through the sterilizing water pipe 34 and then be supplied to a user outside the sink 10 through the second water outlet nozzle 220 .

A second water outlet valve 62 may be installed on the sterilizing water pipe 34 . The second water outlet valve 62 may be installed between the sterilizing water pipe 34 and the water outlet 200 .

The second water outlet valve 62 can supply the sterilized water flowing toward the water outlet 200 through the sterilizing water pipe 34 to the water outlet 200 or discharge it through a separate drain pipe 50. .

In addition, a first water outlet valve 61 may be installed on the second common pipe 39 . The first water outlet valve 61 may be installed between the second common pipe 39 and the water outlet 200 .

The first water outlet valve 61 supplies purified water, cold water, and hot water flowing toward the water outlet 200 through the second common pipe 39 to the water outlet 200, or a separate drain pipe 50 can be emitted as

For example, the first water outlet valve 61 and the second water outlet valve 62 each have one inlet and a first outlet and a second outlet that are selectively opened, and selectively open and close the two outlets. It may be provided as a 3-way valve including an actuator. At this time, the first outlet may be connected to the water outlet nozzles 210 and 220, and the second outlet may be connected to the drain pipe 50.

In detail, the inlet of the first water outlet valve 61 is connected to the second common pipe 39, the first outlet is connected to the first water outlet nozzle 210, and the second outlet is connected to the drain pipe 50. do.

In addition, the inlet of the second water outlet valve 62 is connected to the sterilizing water pipe 34, the first outlet is connected to the second water outlet nozzle 220, and the second outlet is connected to the drain pipe 50. .

For reference, the drain pipe connected to the first water outlet valve 61 and the drain pipe connected to the second water outlet valve 62 may be provided separately, or one drain pipe may be used in common.

On the other hand, as shown in FIG. 1, the water outlet 200 may be mounted on the sink 10 such that at least a portion thereof is exposed to the top of the sink 10. Accordingly, the body 230 and the first water outlet nozzle 210 and the second water outlet nozzle 220 extending to one side of the body 230 may be exposed to the outside while being positioned above the sink 10.

In the prior art, as in the present invention, a device configured to discharge purified water, hot water, purified water, and sterilized water through a water discharge nozzle exposed to the outside of a sink has not been proposed.

However, in the present invention, the water outlet nozzle is configured so that cold, hot, purified water and sterilized water can be discharged from one water outlet.

Even if the water outlet is configured so that purified water, cold water, hot water, and sterilized water are discharged out of the sink, if the water outlet nozzle is arranged so that purified water, cold water, hot water and sterilized water are not discharged at the same point, the user can wash vegetables, fruits, etc. When washing, first, bacteria and dirt on the surface of vegetables and fruits are first washed under the sterilizing water outlet nozzle, and the vegetables and fruits washed with sterilized water are moved to the bottom of the outlet nozzle where purified water is discharged, There is no choice but to discharge the purified water and remove the sterilizing water on the vegetables and fruits by washing them a second time. Therefore, as the first washing and the second washing are performed in different places, the washing process is inevitably very cumbersome.

However, in the case of the present invention, the object to be washed is placed in one location, sterilized water is discharged through the second water outlet nozzle 220, and after the first washing, the first water outlet disposed above the second water outlet nozzle 220 Purified water may be discharged through the nozzle 210 to finish washing the purified water. Therefore, as the first washing and the second washing are performed in one place, the washing process can be greatly simplified.

In addition, water mainly used by users is purified water, hot water, and cold water. Sterilized water may only be discharged under special circumstances. Therefore, in the present invention, the first water extraction nozzle 210 is disposed above the second water extraction nozzle 220 so that the user can select purified water discharge without selecting sterilizing water discharge in an unconscious state.

In general, when sterilized water is discharged and consumed, hypochlorous acid is contained in the sterilized water, which is not beneficial to the user's health.

For this reason, in the present invention, the first water outlet nozzle 210 capable of dispensing cold, hot, and purified water is disposed on the upper side of the cylindrical body portion 230, and the second water outlet nozzle 220 through which sterilizing water is discharged is disposed on the lower side. did

In addition, as shown in the drawing, the width and extended length of the first water outlet nozzle 210 through which purified water, hot water, and cold water are discharged are wider and longer than those of the second water discharge nozzle 220 through which sterilized water is discharged from the lower portion. . Therefore, the second water outlet nozzle 220 through which sterilizing water is discharged can be concealed by the first water outlet nozzle 210 .

In addition, in the prior art, an individual rotation structure of water extraction nozzles arranged up and down has been disclosed.

In the present invention, the upper water outlet nozzle and the lower water outlet nozzle have a structure in which they can rotate separately. If the upper water outlet nozzle and the lower outlet nozzle do not rotate independently but have a structure that rotates simultaneously, the lower outlet nozzle may interfere with the container receiving water when dispensing hot, cold, or hot water from the upper outlet nozzle. there is. Therefore, the two water outlet nozzles are disposed inside the cylindrical body 230 forming the outer shape, and are configured to have a structure capable of rotating at a predetermined angle with respect to the cylindrical inner member 260 fixed to the sink. The first water outlet nozzle 210 and the second water outlet nozzle 220 may be designed to rotate about 180 degrees.

In addition, in the case of the present invention, in order to prevent the two independently rotating water extraction nozzles 210 and 220 from randomly moving due to external interference, that is, to prevent unwanted rotation by the user, a gap between the fixed body and the rotating body is formed. A plurality of O-rings and angular rings were placed.

For reference, the 'rotating body' may refer to the first water outlet nozzle 210 and the second water outlet nozzle 220. In addition, the 'fixed body' may refer to the body portion 230, the inner member 260 to be described later, the first and second connecting members 214 and 215, and the coupling member 216 to be described later.

Each of the O-rings and each ring is made of a material having elasticity. In addition, the first water outlet nozzle 210 and the second water outlet nozzle 220 may be fixed to positions set by the user by the action of the O-ring and each ring.

In particular, in the case of the O-ring, friction is formed in the circumferential direction, and in the case of the angular ring, friction is formed in the vertical direction by forming a predetermined height. Therefore, in the case of the first water outlet nozzle 210 and the second water outlet nozzle 220, shaking in the circumferential direction and the vertical direction (axial direction) can be prevented by the O-ring and the angular ring. In addition, the O-ring and each ring can hold the gap between each component. While friction is generated by the O-ring and each ring, rotation of the first water outlet nozzle 210 and the second water outlet nozzle 220 proceeds smoothly, and the feeling of operation can be improved, and the first water outlet nozzle 210 and the second water outlet 220 can be rotated smoothly. The nozzle 220 may be fixed in a rotated position.

In addition, a display and input unit 240 may be provided in the water outlet 200 .

For example, the display and input unit 240 may be provided in a touch screen manner. The display and input means 240 may include an input unit for inputting various commands and settings, including a water extraction button 244, and a display unit for externally displaying various conditions.

For example, the display and input unit 240 may be provided on the upper surface of the first water outlet nozzle 210 . Therefore, the display and input unit 240 may be located on the uppermost side of the water outlet 200 .

And, the display and input unit 240 selects hot water, purified water, cold water, sterilization water, water extraction command function, cold water and hot water temperature setting and display function, drain selection function, filter replacement cycle notification function, and discharged water capacity. It is possible to perform a setting function, a function to set the extraction time of water to be discharged, and the like.

In addition, a sterilizing water selection button and a sterilizing water outlet button are also provided on the upper side of the first water outlet nozzle 210, so that the user can always recognize the water to be discharged.

The display and input means are provided in the water extraction nozzle, and include a first input unit for selecting the sterilizing water as the water output, a second input unit for setting the output water capacity, and a display unit for displaying the output water capacity. can do ha

Here, the sterilizing water selection button may refer to the first input unit, the capacity selection button may refer to the second input unit, and the capacity display unit may refer to the display unit.

The water extraction button 244 may be disposed vertically above the first cock 219 to be described later. That is, the water extraction button 244 may be formed at a position overlapping the first cock 219 in the vertical direction.

Hereinafter, with reference to FIGS. 1 and 2, a process of dispensing purified water, cold water, hot water, and sterilized water in the water dispensing device according to the present invention will be described.

The main body 100 receives raw water through a raw water pipe 20 connected to a water supply source such as a water pipe, a water tank, or an underground water pipe. A pressure reducing valve 21 is installed on the raw water pipe 20, and raw water is reduced to a set pressure while passing through the pressure reducing valve 21.

Also, the decompressed raw water flows into the filter 120 through a pipe connecting the pressure reducing valve 21 and the filter 120 . The raw water that has passed through the filter 120 is purified by removing foreign substances. In addition, when the inlet valve 35 is opened, purified water passing through the filter 120 passes through the flow sensor 36 while flowing through the water outlet pipe 30 .

At this time, the flow rate detected by the flow sensor 36 may be used as data required for output control of the hot water tank 130 or the cold water tank 140 .

Meanwhile, purified water passing through the flow sensor 36 flows along the water outlet pipe 30 . And, it can be branched into a sterilizing water side, a cold water-purifying water side, and a hot water side.

First, the purified water branched into the cold water-pure water side is branched into the cold water side and the purified water side again and flows into the purified water pipe 31 and the cold water pipe 32, respectively. The purified water pipe 31 and the cold water pipe 32 are provided with a purified water valve 41 and a cold water valve 42 for regulating the flow of water, respectively. The purified water valve 41 and the cold water valve 42 can be selected by the user's operation to select purified water or cold water, and the selected valve is opened through the user's manipulation of the water extraction button, so that purified water or cold water can be supplied through the first water extraction nozzle 210. ) through which it can be supplied to the user.

In detail, when the user requests cold water dispensing, the cold water valve 42 is opened. As described above, when the cold water valve 42 is opened, the purified water of the outlet pipe 30 passes through the cold water pipe 32 and the cold water valve 42, and the water in the cold water pipe 32 enters the cold water tank 140. passes through the cooling coil of The water flowing along the cooling coil exchanges heat with the cooling water inside the cold water tank 140 and is cooled to cold water. To this end, the cooling water is continuously cooled to maintain the set temperature.

The cold water passing through the cold water tank 140 flows toward the water outlet 200 through the first common flow path 38 and the second common flow path 39 connected to the cold water pipe 32, and the first water outlet valve 61 ), it can be supplied to the first water outlet nozzle 210.

For reference, a compressor may be driven to cool the cooling water. The operation of the compressor may be determined by a cold water temperature sensor provided inside the cold water tank 140 . Therefore, the cooling water can always maintain a set temperature, and for this purpose, driving of the compressor can be controlled. The compressor is an inverter compressor, the frequency of which is adjusted in response to a required load, and the cooling capacity can be adjusted. That is, the compressor can be driven by inverter control and can cool the cooling water with optimum efficiency.

Meanwhile, when a user requests purified water, the purified water valve 41 is opened. As described above, when the water purification valve 41 is opened, purified water from the water outlet pipe 30 passes through the water purification pipe 31 and the water purification valve 41, and the first common flow path 38 connected to the water purification pipe 31 And through the second common flow path 39, it flows toward the water outlet 200 side. Then, it may be supplied to the first water outlet nozzle 210 through the first water outlet valve 61 .

Meanwhile, when the user requests hot water to be discharged, the hot water valve 43 is opened. When the hot water valve 43 is opened as described above, purified water from the outlet pipe 30 passes through the hot water pipe 33 and the hot water valve 43 . In addition, the flow rate of the water passing through the hot water pipe 33 may be controlled by the flow control valve 37 . While passing through the flow control valve 37 as described above, the purified water whose flow rate is adjusted passes through the hot water tank 130. And, in the process of passing the hot water tank 130, it can be heated to a set temperature. The hot water tank 130 may be heated by an induction heating method, and for this purpose, the output of the working coil included in the hot water tank 130 may be adjusted.

The purified water passing through the hot water tank 130 may be heated to a set temperature.

Hot water heated while passing through the hot water tank 130 flows toward the water outlet 200 through the second common flow path 39 connected to the hot water pipe 33 . Then, it may be supplied to the first water outlet nozzle 210 through the first water outlet valve 61 .

Also, the hot water tank 130 may be further connected to the drain pipe 50. The drain pipe 50 allows steam generated when the water inside the hot water tank 130 boils to be discharged to the outside. In addition, a safety valve 51 is provided in the drain pipe 50, and when a pressure higher than a set pressure is generated, the safety valve 51 is opened to discharge steam to the outside.

In detail, the safety valve 51 is for discharging steam generated when hot water is heated in the hot water tank, and prevents excessive increase in pressure of the inside of the hot water tank due to steam. The safety valve 51 is configured to be opened at a set pressure, and may have various structures in which steam in the hot water tank can be discharged smoothly.

In the case of the drain pipe for discharging steam, it may be formed separately from the drain pipe connected to the first water outlet valve 61 and the second water outlet valve 62 . Also, in the case of the drain pipe for discharging steam, the drain pipe connected to the first water outlet valve 61 and the second water outlet valve 62 may join.

For reference, the hot water tank 130 may generate instantaneous hot water using an induction heating method. In addition, when the water flow rate flowing into the hot water tank 130 is small due to the characteristics of instantaneous hot water, boiling may occur in the hot water tank 130 .

In the case of the present invention, in order to prevent this, a temperature sensor is mounted on a heat sink of an element (eg, IGBT) included in a control module that supplies an output to the hot water tank. And, when the temperature of the heat sink exceeds a set temperature (eg, 70° C.), the supply of output to the hot water tank 130 is stopped.

For example, the hot water tank 130 may include an induction heating assembly for making hot water and a control unit for controlling driving of the induction heating assembly and valves. The induction heating assembly and the control unit may be coupled to each other as one module, and may be mounted inside the housing 110 in a coupled state.

The induction heating assembly is configured to receive purified water supplied to the hot water tank 130 and heat it as hot water, and to be heated by an induction heating (IH) method. The induction heating assembly may include a working coil (not shown) for heating water passing through the hot water tank 130 .

In the case of the water dispensing device according to the present invention as described above, cold water, purified water, and hot water may be discharged to the outside through one first water discharge nozzle 210 .

For reference, the first water outlet valve 61 is provided with a temperature sensor 68 (see FIG. 7B) for measuring the temperature of the cold water and hot water supplied through the second common pipe 39, and the temperature sensor is connected to the second common pipe 39. The temperature of cold water and hot water supplied from the pipe 39 is sensed. Further, the first water outlet valve 61 supplies cold water and hot water to the first water outlet nozzle 210 when the temperature sensed by the temperature sensor is within the preset satisfaction range, and the detected temperature falls within the preset satisfaction range. If not included, purified water, cold water, and hot water may be discharged to the drain pipe 50 side.

The temperature sensor (68, see FIG. 7B) may be installed on the flow path of the first water outlet valve (61). In detail, the temperature sensor 68 (see FIG. 7B) may be installed to be exposed on the side of the inlet through which cold/hot water flows.

In addition, when hot water or cold water is discharged, when the user presses the water discharge button, the water in the pipe is unconditionally drained regardless of whether the temperature is satisfied, and then hot water and cold water may be discharged.

In detail, when the user requests cold water discharge, the water (residual water) filled between the cold water tank 140 and the first water discharge valve 61 is automatically drained through the drain pipe 50, and the discharge of the residual water proceeds. After that, the water in the cold water tank 140 may be supplied to the first water outlet nozzle 210 through the first water outlet valve 61 . Therefore, only cold water can be supplied to the user.

In addition, when the user requests hot water outlet, the water (residual water) filled between the hot water tank 130 and the first water outlet valve 61 is automatically drained through the drain pipe 50, and the residual water is discharged. Afterwards, water in the hot water tank 130 may be supplied to the first water outlet nozzle 210 through the first water outlet valve 61 . Therefore, only hot water can be supplied to the user.

On the other hand, in the case of purified water, the extraction of purified water may proceed immediately without draining residual water.

Meanwhile, when the user requests the sterilizing water to be discharged, the sterilizing water valve 44 is opened. As described above, when the sterilizing water valve 44 is opened, purified water in the water outlet pipe 30 passes through the sterilizing water pipe 34 and the sterilizing water valve 44, and the water in the sterilizing water pipe 34 is sterilizing water. It passes through module 150. Then, the sterilizing water generated in the sterilizing water module 150 flows to the water outlet 200 along the sterilizing water pipe 34, passes through the second water outlet valve 62, and passes through the second water outlet nozzle 220. can be supplied externally.

Due to the nature of the undersink water purifier, the distance between the body part 100 installed inside the sink and the water outlet part 200 installed outside the sink is large, and the passage connecting them becomes long. In addition, since the residual water remaining in the flow path affects the water outlet temperature, the valves 61 and 62 are installed as close as possible to the water outlet 200 to selectively drain the residual water remaining in the flow path. can be made to satisfy the temperature performance.

That is, according to the present invention, after draining the residual water remaining in the long passage connecting the main body 100 and the water outlet 200 through the valve 61 installed directly below the water outlet 200, Only produced direct water (hot water or purified water) may be discharged through the water extraction nozzle 210 to satisfy the target extraction temperature.

Also, the plate 241 may be larger than the top surface of the frame 241 . Therefore, at least a portion of the boundary portion 241a of the plate 241 protrudes outward from the frame 241, and accordingly, even if water or foreign matter flows between the plate 241 and the first water outlet nozzle 210, the frame ( Water or foreign matter passes between the sidewalls 242g (see FIG. 22) of the frame 241, and as a result, the inflow of water or foreign matter into the PCB disposed inside the sidewall 242g (see FIG. 22) of the frame 241 is prevented. can That is, waterproof performance can be improved.

In addition, a step 213a may be formed on the inner side along the circumference of the open top of the first water outlet nozzle 210 . Also, the boundary portion 241a of the plate 241 may be seated on the stepped portion 213a. The depth of the step 213a may be formed as much as the thickness of the plate 241 . In this case, the open top of the first water outlet nozzle 210 and the plate 241 may form a plane.

The first water outlet nozzle 210 forms a first insertion portion 212 extending downward to be inserted inward from the upper end of the second body 232 at the lower end of one side. The first insertion part 212 may have a hollow cylindrical shape. The outer diameter of the first insertion portion 212 may be smaller than or equal to the inner diameter of the second body 232 . The first insertion part 212 may be formed on the opposite side of the water outlet 211 . The outer diameter of the first insertion portion 212 may be smaller than the width of the first water extraction nozzle 210 (length in a direction crossing the extension direction of the water extraction nozzle). Accordingly, a step 212a may be formed between the upper end of the first insertion part 212 and the lower end of the first water outlet nozzle 210 . Also, the outer surface of the rear end (right side of FIG. 4 ) of the first water outlet nozzle 210 and the outer surface of the second body 232 may be connected smoothly.

In addition, the outer diameter of the first insertion portion 212 may gradually decrease from the upper side to the lower side. In addition, the inner diameter of the second body 232 into which the first insertion part 212 is inserted may gradually decrease from the upper side to the lower side. Therefore, the operation of inserting the first insertion part 212 into the second body 232 can be easily performed.

Meanwhile, a first cock 219 having a water outlet 211 is disposed at the front end of the first water outlet nozzle 210 . The first cock 219 is connected to the first water outlet valve 61 through the second common pipe 39. Therefore, cold water, hot water, and purified water passing through the first water outlet valve 61 may be supplied to the first cock 219 through the second common pipe 39 . The second common pipe 39 serves to guide cold water, hot water, and purified water to the first water outlet valve 61, and at the same time, cold water, hot water, and purified water passing through the first water outlet valve 61 are discharged from the first cock. (219). In this case, it can be understood that the first water outlet valve 61 is installed on the second common pipe 39.

In addition, a first cock installation hole in which the first cock 219 is installed may be formed at the front end of the first water outlet nozzle 210 . The first cock 219 may pass through the first cock installation hole from the upper side to the lower side, so that at least a portion of the first cock 219 may be exposed to the lower side of the first water outlet nozzle 210 .

On the other hand, the second water outlet nozzle 220 forms a second insertion portion 222 extending downward to be inserted inward from the upper end of the first body 231 at the lower end of one side. The second insertion part 222 may have a hollow cylindrical shape. The outer diameter of the second insertion portion 222 may be smaller than or equal to the inner diameter of the first body 231 . The second insertion part 222 may be formed on the opposite side of the water outlet 221 . The outer diameter of the second insertion portion 222 may be smaller than the width of the second water extraction nozzle 220 (length in a direction crossing the extending direction of the water extraction nozzle). Accordingly, a step 222a may be formed between the upper end of the second insertion part 222 and the lower end of the second water outlet nozzle 220 . Also, the outer surface of the rear end (right side of FIG. 4 ) of the second water outlet nozzle 220 and the outer surface of the first body 231 may be connected smoothly.

Meanwhile, a second cock 229 having a water outlet 221 is disposed at the front end of the second water outlet nozzle 220 . The second cock 229 is connected to the second water outlet valve 62 through the sterilizing water pipe 34. Therefore, the sterilizing water passing through the second water outlet valve 62 can be supplied to the first cock 219 through the sterilizing water pipe 34 . The sterilizing water pipe 34 serves to guide the sterilizing water to the second water outlet valve 62 and at the same time guides the sterilizing water passing through the second water outlet valve 62 to the second cock 229. there is. In this case, it can be understood that the second water outlet valve 62 is installed on the sterilizing water pipe 34 .

In addition, a through hole 220d opened to expose the second cock 229 downward may be formed in the lower frame 220a of the second water outlet nozzle 220 to be described later.

The second cock 229 may pass through the passage hole 220d from the upper side to the lower side, so that at least a portion of the second cock 229 may be exposed to the lower side of the lower frame 220a.

The lower frame 220a may form an extension wall extending upward along the circumference. The extension wall is accommodated inside the second water outlet nozzle 220 .

In addition, the width of the first water outlet nozzle 210 (the length in the left and right directions in reference to FIG. 4 ) may be larger than the width of the second water outlet nozzle 220 . Also, the length of the first water extraction nozzle 210 (the length in the extension direction of the water extraction nozzle) may be longer than that of the second water extraction nozzle 220 .

In detail, the water outlet 211 formed at the tip of the first water outlet nozzle 210 may be formed at a position more protruding than the tip of the second water outlet nozzle 220 . Therefore, water discharged from the first water outlet nozzle 210 can be supplied to the user without touching the second water outlet nozzle 220 .

That is, in a state where the first water extraction nozzle 210 and the second water extraction nozzle 220 are placed side by side facing the same direction, the water outlet 211 of the first water extraction nozzle 210 is the second water extraction nozzle ( 220) and may be formed at a position that does not overlap in the vertical direction.

In addition, as described above, in the case of the second water outlet nozzle 220, compared to the first water outlet nozzle 210, the length is shorter and the height is lower, so water can be discharged smoothly only inside the sink bowl 12 of the sink 10. . That is, since the lower space of the second water outlet nozzle 220 is narrow, sterilizing water can be easily discharged only in a state in which the second water outlet nozzle 220 is positioned toward the sink bowl 12 of the sink 10. Therefore, the sterilizing water can be induced to be discharged only from the inside of the sink bowl 12 as much as possible. Further, the rotation of the second water outlet nozzle 220 may be limited to the rotation range only within the sink bowl 12 .

On the other hand, in the case of the first water outlet nozzle 210, compared to the second water outlet nozzle 220, since the length is longer and the height is higher, water can be freely dispensed even outside the sink 10. That is, the lower space of the first water outlet nozzle 210 is secured relatively wide, and cold water, hot water, and purified water can be discharged smoothly in a state where a container such as a cup is placed below the first water outlet nozzle 210. there is.

In addition, since the first water outlet nozzle 210 is larger in size and positioned higher than the second water outlet nozzle 220, the user can more easily recognize the first water outlet nozzle 210 than the second water outlet nozzle 220. And, while operating more easily, cold / hot / purified water can be dispensed.

If you want to receive cold water, hot water, or purified water from a container such as a pot that is higher than the first water outlet nozzle 210, put a large container such as a pot into the sink bowl 12, and use the first water outlet nozzle 210 In a state of being rotated to be positioned on the upper side of a large container such as a pot, water is discharged to receive cold water, hot water, or purified water into a large container such as a pot.

The first water outlet nozzle 210 may have curved portions 213 formed convexly forward and backward at both end portions, respectively. The second water outlet nozzle 220 may have a rounded tip at which the water outlet 221 is formed. In addition, a cylindrical connecting portion 223 may be formed at the rear end. The second insertion part 222 is formed at the lower end of the connection part 223 . An outer diameter of the connection part 223 may be formed larger than a width of the second water extraction nozzle 220 .

The radius of curvature of the outer surface of the curved portion 213, the outer diameter of the connecting portion 223, and the outer diameters of the first body 231 and the second body 232 may be formed identically.

In addition, the first water outlet nozzle 210 and the second water outlet nozzle 220 are freely rotatable while being coupled to the sink 10 . For example, the first water extraction nozzle 210 and the second water extraction nozzle 220 may rotate in a range of 180 degrees. As another example, the first water extraction nozzle 210 rotates within a range of about 180 degrees, and the second water extraction nozzle 220 may also rotate within a range of about 180 degrees.

The first water outlet nozzle 210, the second water outlet nozzle 220, and the body 230 are exposed to the outside of the sink. Therefore, it has no choice but to come into contact with water and is bound to rust. Therefore, the first water outlet nozzle 210, the second water outlet nozzle 220, and the body portion 230 may be formed of a plastic material to prevent rust.

Figure 7b is a front view showing another example of the coupling portion of the water outlet and the sink. 7C is a view showing an example of operation of the first water outlet valve and the second water outlet valve.

Hereinafter, with reference to the drawings, the coupling structure of the water outlet 200 and the sink 10, which are the main components of the present invention, will be described.

4 to 7c, the water outlet 200 according to the present invention may further include a penetrating member 250 penetrating the sink 10.

The upper side of the penetrating member 250 is located on the upper side of the sink 10, and the lower side is located on the lower side of the sink 10. A screw 251 having a thread formed on an outer circumferential surface may be formed at a lower side of the penetrating member 250 . The penetrating member 250 may have a flange 252 formed by extending an outer diameter at a central portion. The flange 252 may have a screw thread 252a formed on an outer circumferential surface and fastened with a screw thread 231a formed on a lower inner circumferential surface of the first body 231 .

Also, by fastening the screw threads 231a and 252a, the penetrating member 250 and the first body 231 may be coupled.

Meanwhile, an extension 253 having a smaller diameter than the flange 252 and extending upward may be formed on the upper side of the flange 252 . In addition, the penetrating member 250 may form a hollow part 254 in the vertical direction. The hollow part 254 passes through the extension part 253 , the flange 252 , and the screw 251 .

The sterilizing water pipe 34 and the second common pipe 39 can pass through the hollow part 254, and the sterilizing water pipe 34 passing through the hollow part 254 is the second water outlet nozzle 220. ), and the second common pipe 39 passing through the hollow part 254 is inserted into the second water outlet nozzle 210.

In addition, the extension part 253 is accommodated inside the inner member 260 to be described later. And, the inner member 260 is accommodated inside the first body 231. Therefore, through the hollow part 254 of the penetrating member 250, when the pipes 34 and 39 are inserted inside the sink, the pipe 34 passing through the hollow part 254 without being caught by a step, 39) can be smoothly inserted into the first body 231 and the inner member 260.

On the other hand, the inner member 260 has a hollow tube shape with open top and bottom. And, the upper end of the inner member 260 is accommodated inside the second body 232 and inside the insertion part 212 . And, the lower end of the inner member 260 is accommodated inside the first body 231 . Also, the extension part 253 of the penetrating member 250 is inserted into the lower end of the inner member 260 .

The inner member 260 may be formed in a cylindrical shape. The inner member 260 is fixed to a sink, has a cylindrical shape, and serves as a rotating shaft of the first water outlet nozzle 210 and the second water outlet nozzle 220. That is, the inner member 260 maintains a fixed state when the first water outlet nozzle 210 and the second water outlet nozzle 220 rotate. The inner member 260 may be formed of a rigid material. The inner member 260 may be formed of a metal material. The inner member 260 may be formed of an aluminum material.

A hole having the same size as or larger than the screw 251 of the penetrating member 250 is formed in the sink 10 . Then, through the hole, the screw 251 of the penetrating member 250 penetrates the sink 10. Therefore, the screw 251 of the penetrating member 250 is exposed at the lower end of the sink 10. Then, the screw 251 of the penetrating member 250 exposed to the lower side of the sink 10 is fastened to the nut member 270. Thus, the penetrating member 250 may be fixed to the sink 10.

The extension part 253 forms a plurality of grooves 255 (see FIG. 4) on the outer circumferential surface, and a groove part 268 (see FIG. 4) can be formed.

Also, a coupling piece 298 may be inserted between the grooves 255 and 268. The coupling piece 298 may be formed of an elastic material.

The grooves 255 and 268 and the coupling piece 298 may be provided as a pair, respectively, and may be formed at opposite positions. That is, the grooves 255 and 268 and the coupling piece 298 may be formed at symmetrical positions with respect to the central axes of the penetrating member 250 and the inner member 260 .

With the configuration of the grooves 255 and 268 and the coupling piece 298 as described above, the distance between the extension portion 253 and the inner member 260 is secured, and at the same time, the bonding force between the extension portion 253 and the inner member 260 is secured. It can be.

In addition, a sealing O-ring 299 may be inserted between the flange 252 of the penetrating member 250 and the upper surface of the sink 10 . To this end, a groove into which the sealing member 299 is inserted may be formed concave upward at an outer lower end of the flange 252 of the penetrating member 250 .

With the configuration of the sealing O-ring 299, the gap between the flange 252 of the penetrating member 250 and the sink 10 is caught, and the coupling force between the flange 252 of the penetrating member 250 and the sink 10 is can be improved Then, while friction occurs between the penetrating member 250, the inner member 260 and the first body 231 and the sink 10, the penetrating member 250, the inner member 260 and the first body 231 Can be more securely fixed to the sink (10).

8 is a view of a state in which a nut member and a screw are fastened as seen from below. 9 is a side view of a state in which a nut member and a screw are fastened;

Referring to FIGS. 8 to 9 , a screw thread is formed on an inner circumferential surface of the nut member 270 to be fastened with the screw 251 .

In addition, the nut member 270 may have a prism-shaped body 274 . For example, the body 274 may be formed in the shape of a hexagonal column.

In addition, the nut member 270 may form a fastening hole 271 having a screw thread formed on an inner circumferential surface thereof. In addition, the nut member 270 may form an extension 273 extending in a disk shape at an upper end adjacent to the sink 10 . A plurality of protrusion-shaped segments may be formed on the upper surface of the expansion part 273 to improve fixing force.

In addition, the nut member 270 may form a pair of hooking parts 275 extending along the radial direction of the extension part 273 at opposite sides of the body 274 . The hooking portion 275 may extend from an outer surface of the body 274 to a boundary of the extension portion 273 .

As described above, when the body of the nut member 270 is provided in the form of a prism, including a hexagonal column, it is easy to rotate the nut member 270 from the side using a tool such as a spanner or pliers. In addition, when the locking portion 275 is formed on the nut member 270 as described above, it is easy for the user to hold the body 274 and rotate the nut member 270 while preventing slipping of the hand. In addition, when the extension part 273 is formed as described above, the contact area with the sink 10 is widened, and the nut member 270 can be more stably coupled with the sink 10. And, the coupling force between the water outlet 200 and the sink 10 can also be improved.

In addition, if the user rotates the nut member 270 by hand and rotates the nut member 270 by one or two rotations as a tightening means, the fastening force can be strengthened.

For reference, a structure for fixing a tap to a sink has been disclosed in Registered Utility Model No. 0276610 (hereinafter referred to as prior literature).

In detail, in the prior literature, a fastening pipe having a thread formed on the outer circumferential surface is formed at the lower part of the faucet to which the cold and hot water pipes are connected, and after the fastening pipe passes through the fastening hole of the sink, the fastening nut is attached to the fastening pipe at the bottom of the sink A technique for fixing a faucet to a sink by inserting it has been disclosed.

At this time, since the lower space of the sink is narrow, a problem in assembling the fastening nut may be difficult. In addition, in the case of a structure in which the water extraction nozzles 210 and 220 rotate as in the present invention, since the nut member 270 may be loosened according to the repeated rotation of the water extraction nozzles 210 and 220, the nut member ( 270) needs to be signed.

In the present invention, to solve this problem, the shape of the nut member 270 is integrally formed with the disk-shaped extension part 273 and the hexagonal column-shaped body 274. In addition, straight hooking parts 275 are formed symmetrically on both sides of the hexagonal columnar body 274,

In addition, the hooking part 275 overlaps with the virtual extension lines EL1 and EL2 of the inclined surfaces 275b and 274c formed on both sides adjacent to one surface 274a of the body 274 to which the hooking part 275 is connected, or , It is formed so as not to protrude beyond the virtual extension lines EL1 and EL2.

Therefore, when the body part 274 is rotated using a tool for fastening the nut member 270, for example, a spanner or pliers, interference of the locking part 275 can be prevented.

And, the hooking part 275 may be formed only on two sides of the body 274 . The reason is that the nut member 270 can be turned by inserting a wrench or the like through the remaining four sides on which the engaging portion 275 is not formed.

Describing the fastening process of the penetrating member 250 and the nut member 270, first, the user inserts the penetrating member 250 from the upper side of the sink 10 into the hole 13 formed in the sink 10 (see FIG. 7A). Insert and fasten the nut member 270 to the screw 251 exposed to the lower side of the sink (10). At this time, even when the user's field of view is blocked, the user can easily and primarily fasten the nut member 270 to the screw 251 by holding the hooking part 275 with his or her hand. At this time, since the locking portion 275 is formed to cross the rotational direction of the nut member 270, the user can easily rotate the nut member 270 while holding the locking portion 275 with his/her hand.

In addition, when the primary fastening is completed as described above, after inserting a separate tool into the body 274, the nut member 270 may be secondarily fastened to the screw 251 by turning the tool. Therefore, the nut member 270 can be more easily and firmly fastened to the screw 251.

In addition, in order to improve the fastening force of the penetrating member 250, the nut member 270, and the sink 10, a rubber washer 276 is placed between the bottom surface of the sink 10 and the extension 273 of the nut member 270. , see FIG. 7A) may be inserted.

Meanwhile, the hole 13 (see FIG. 7A) formed in the sink 10 is smaller than the diameter of the flange 252.

In addition, the diameter of the flange 252 is smaller than the inner diameter of the first body 231 and the inner diameter of the inner member 260 . Accordingly, the flange 252 may be accommodated inside the first body 231 and the inner member 260 .

Meanwhile, the first water outlet valve 61 and the second water outlet valve 62 may be installed inside the water outlet 200 . In detail, the first water outlet valve 61 and the second water outlet valve 62 may be installed inside the first body 231 or the second body 232 .

As another example, the first water outlet valve 61 and the second water outlet valve 62 may be installed outside the water outlet 200 . In detail, the first water outlet valve 61 and the second water outlet valve 62 may be installed outside the first body 231 or the second body 232 .

In this case, the first water outlet valve 61 and the second water outlet valve 62 may be installed under the sink 10 .

The water outlet 200 may further include a bracket 280 on which the first water outlet valve 61 and the second water outlet valve 62 are installed. The bracket 280 includes a horizontal portion 281 inserted between the lower surface of the sink 10 and the nut member 270 and a vertical portion 282 extending vertically from one side of the horizontal portion 281. can include A hole through which the screw 251 of the penetrating member 250 passes may be formed in the horizontal portion 281 . The screw 251 passes through the hole 13 of the sink 10 (see FIG. 7A) and the hole of the horizontal portion 281 in turn, and then, at the lower side of the horizontal portion 281, the nut member 270 and can be contracted.

A reinforcing rib 283 may be formed on an inner surface of the corner defined by the horizontal portion 281 and the vertical portion 282 .

In addition, the first water outlet valve 61 and the second water outlet valve 62 may be coupled to the vertical portion 282 .

In addition, the vertical portion 282 is provided with a plurality of pipe fixing hooks 285 for fixing various pipes 34 and 39 in a gripping manner and valve fixing hooks 286 for fixing the valves 61 and 62. can

In addition, the vertical portion 282 may form an extension wall in a vertical direction with the vertical portion 282 on one side or both sides. In addition, a pipe passage hole or a pipe passage groove 288 through which the various pipes 34 and 39 pass may be formed in the extension wall 287 .

Meanwhile, the first water outlet valve 61 and the second water outlet valve 62 may be vertically disposed on the vertical portion 282 . As another example, the first water outlet valve 61 and the second water outlet valve 62 may be horizontally disposed on the vertical portion 282 . As another example, the first water outlet valve 61 and the second water outlet valve 62 may be displaced from each other on the vertical portion 282 . That is, the first water outlet valve 61 and the second water outlet valve 62 may be respectively disposed at an upper end of one side and a lower end of the other side of the vertical portion 282 .

Referring to FIG. 7A , the first water outlet valve 61 and the second water outlet valve 62 may be arranged so that cold, hot, purified water, and sterilized water flow from the lower side to the upper side. In addition, cold, hot, purified water, and sterilization water may be discharged from the lower side to the upper side toward the water outlet nozzles 210 and 220, and the drain may proceed from the upper side to the lower side.

Referring to FIG. 7B , the first water outlet valve 61 and the second water outlet valve 62 may be disposed so that cold, hot, purified water, and sterilized water flow from right to left. In addition, cold, hot, purified water, and sterilization water may be discharged from the lower side to the upper side toward the water outlet nozzles 210 and 220, and the drain may proceed from the left side to the right side.

Hereinafter, the opening and closing operations of the first water outlet valve 61 and the second water outlet valve 62 will be described with reference to FIG. 7C.

The first water outlet valve 61 and the second water outlet valve 62 may be opened and closed by a plunger 66 that moves up and down by an electric signal.

First, as shown in (a) of FIG. 7C, when the plunger 66 rises, a passage connecting the inlet 63 through which water is introduced and the outlet 64 through which water is discharged is opened.

At this time, the inlet 63 and the outlet 64 are formed at opposite positions. That is, it is formed on both sides based on the plunger 66. Accordingly, the water introduced through the inlet 63 is discharged through the outlet 64, and the water discharged through the outlet 64 is supplied to the water outlet nozzles 210 and 220.

At this time, as the plunger 66 rises, the passage connecting the drain hole 65 and the inlet 63 is blocked.

The drain hole 65 may be arranged in a vertical direction with the inlet 63 (refer to FIG. 7C).

A sealing portion 67 may be formed below the plunger 66 to prevent leakage.

Meanwhile, the temperature sensor 68 may be installed to be exposed on the inlet 63 side.

The temperature sensor 68 may be installed to be exposed between the inlet 63 side and the branch point 69 opened and closed by the plunger 66 based on the flow of water.

On the other hand, as shown in (b) of FIG. 7C, when the plunger 66 descends, the passage connecting the inlet 63 through which water is introduced and the outlet 64 through which water is discharged is blocked.

Also, as the plunger 66 descends, the passage connecting the drain hole 65 and the inlet 63 is opened.

Accordingly, the water introduced through the inlet 63 exits through the drain hole 65, and the water that flows through the drain hole 65 is drained.

For reference, the temperature sensor described above and the temperature sensor described later may be installed on the inlet 63 side. In addition, based on the temperature sensor described above and the direction in which water flows, the temperature sensor may be installed between the inlet 63 and the plunger 66.

Due to the nature of undersink water purifiers, a water outlet nozzle coming out of the sink is required.

In the case of the present invention, a water outlet nozzle for drinking water (cold, hot, purified water) and a water outlet nozzle for sterilized water are distinguished, but each water outlet nozzle is implemented as a single body and independently rotatable.

In addition, in the case of the first water outlet nozzle, touch input and display output are possible.

As each of the water extraction nozzles rotates left and right as described above, user convenience can be maximized.

<Structure limiting rotation angle of water outlet nozzle>

10 is a cross-sectional view of a first water outlet nozzle, which is a part of the present invention. 11 is an enlarged view of a portion of FIG. 10 . And, FIG. 12A is a view from the top of a state in which the display and input means are separated from the first water outlet nozzle. Also, FIG. 12B is an enlarged view of a portion of FIG. 12A. 13 is a view showing a state in which a first connection member, a second connection member, and a coupling member, which are some components of the present invention, are coupled.

Referring to FIGS. 10 to 13 , the rotation angle of the first water outlet nozzle 210 may be limited. For example, the first water extraction nozzle 210 may rotate in a range of 90 degrees to 270 degrees. To this end, a rotation limiting structure for limiting the rotation angle of the first water extraction nozzle 210 is required.

In the case of the first water outlet nozzle 210, a first stopper 2111 protruding into the inner hollow of the insertion part 212 may be formed at the rear end of the lower frame 2110 forming the bottom surface. The first stopper 2111 protrudes to the right with reference to FIG. 10 .

And, inside the insertion part 212, when the first water outlet nozzle 210 rotates, there is a ring-shaped first connecting member 214 that does not rotate together and maintains a fixed state. can be formed Rotation limiting protrusions 214a protruding upward may be formed on both sides of the first connection member 214 to limit rotation of the first stopper 2111 .

<Sterilization water module>

24 is a perspective view of a sterilizing water module, which is a part of the present invention. 25 is an exploded perspective view of a sterilizing water module, which is a part of the present invention. 26 is a cross-sectional view of an electrode part included in a sterilizing water generating module, which is a part of the present invention.

Referring to the drawings, the sterilizing water module 150 according to the present invention includes a casing 1510, an electrode unit 1520, a spacer 1530, and a cap 1540.

First, the casing 1510 forms the outer body of the sterilizing water module 150.

A space in which the electrode unit 1520 and the spacer 1530 are accommodated is formed inside the casing 1510 . The casing 1510 has one side open to form an opening 1511, and the other side has a discharge pipe 1512 through which sterilizing water is discharged. The casing 1510 may have a box shape at least partially flat.

The thickness or width of the inner space defined by the casing 1510 may maintain a constant size along the longitudinal direction so that a constant water pressure is maintained during water inflow and outflow.

The opening 1511 of the casing 1510 may be shielded by a cap 1540 . For example, a cylindrical inlet 1513 may be formed at one end of the casing 1513 where the opening 1511 is formed, and the cap 1540 may also be formed in a cylindrical shape. The cap 1540 may be coupled to the casing 1510 in a form surrounding the inlet 1513 of the casing 1510 in which the opening 1511 is formed. The inlet 1513 may have a stepped shape with an outer diameter gradually increasing from the upper side to the lower side. A plurality of grooves 1513b may be formed on an outer surface of an end of the inlet 1513 .

Meanwhile, the cap 1540 may include an upper cap 1541 and a lower cap 1542.

The upper cap 1541 may have a hollow shape so that at least a portion of the casing 1510 may pass therethrough.

The upper cap 1541 may be inserted downward from the upper side (refer to FIG. 25 ) where the discharge tube 1512 of the casing 1510 is formed. Also, the upper cap 1541 may be seated on the upper side of the inlet 1513 in a form surrounding the inlet 1513 from the upper side.

The lower cap 1542 is fastened to the upper cap 1541 while shielding the opening 1511 at the lower side of the casing 1510 . For example, a screw thread 1543 may be formed on an outer circumferential surface of the lower side of the upper cap 1541 . Also, a screw thread (not shown) to which the screw thread 1543 of the upper cap 1541 is fastened may be formed on an inner circumferential surface of an upper end of the lower cap 1542 .

When the upper cap 1541 and the lower cap 1542 are fastened as described above, the opening 1511 of the casing 1510 may be shielded by the cap 2540 .

In addition, an O-ring 1550 for sealing may be inserted between the upper cap 1541 and the lower cap 1542 or between the casing 1510 and the cap 1540 .

An inlet pipe 1544 into which purified water supplied from the sterilizing water pipe 34 flows may be formed in the lower cap 1542 . The inlet pipe 1544 may be connected to the sterilizing water pipe on the filter side, and the discharge pipe 1512 may be connected to the sterilizing water pipe on the water outlet 200 side.

In addition, non-slip protrusions 1545 and 1546 may be respectively formed on the outer surface of the upper cap 1541 and the outer surface of the lower cap 1542 to prevent the user's hand from slipping. On the outer surface of the upper cap 1541 and the outer surface of the lower cap 1542, grooves and protrusions may be alternately formed along the circumferential direction to form the non-slip protrusions 1545 and 1546.

In addition, the casing 1510 may include a plurality of reinforcing ribs 1514 integrally formed on the outer surface.

Surfaces of the casing 1510 facing each other may form a plane. The plurality of reinforcing ribs 1514 provided on the outer surface of the flat-shaped casing 1510 may be composed of a plurality of transverse reinforcing ribs and longitudinal reinforcing ribs. The plurality of longitudinal reinforcing ribs and the plurality of transverse reinforcing ribs may form a grid pattern while crossing each other.

With the configuration of the plurality of reinforcing ribs 1514 as described above, the pressure resistance performance of the casing 1510 can be further improved.

Meanwhile, the outer appearance of the sterilizing water module 150 is formed by the casing 1510 and the cap 1540 as described above.

The sterilizing water module 150 may be disposed such that the inlet pipe 1544 faces downward and the discharge pipe 1512 faces upward. Accordingly, water obtained through the inlet pipe 1544 may flow upward from the inner lower portion of the casing 1510 . The discharge pipe 1512 is located on the upper side of the casing 1510, and sterilizing water may be discharged to the outside of the casing 1510 through the discharge pipe 1512.

The inlet pipe 1544 and the discharge pipe 1512 are connected to the sterilizing water pipe 34, respectively. Therefore, the purified water flowing into the sterilizing water pipe 34 flows into the sterilizing water module 150 through the inlet pipe 1544, and the sterilizing water generated in the sterilizing water module 150 sterilizes through the discharge pipe 1512. After exiting the water module 150, the sterilized water may be supplied to the water outlet 200 through the pipe 34.

As described above, when the inlet pipe 1544 through which purified water is introduced is disposed on the lower side and the discharge pipe 1512 through which sterilizing water is discharged is provided on the upper side, water flows slowly from the lower side to the upper side, and in the process of generating sterilizing water After the generated air bubbles are collected upward, they may escape through the discharge pipe 1512 .

If the inlet pipe 1544 is located on the upper side of the casing 1510, the water obtained through the inlet pipe 1544 flows rapidly downward due to gravity, and the purified water does not sufficiently react with the electrode unit 1520. There is a possibility that it will be discharged without it. Accordingly, it is difficult to secure a desired concentration of sterilizing water.

In addition, when the inlet pipe 1544 and the discharge pipe 1512 are arranged in a horizontal direction, bubbles generated in the process of generating the sterilizing water are not smoothly discharged, resulting in a decrease in the efficiency of generating the sterilizing water.

In order to prevent this problem, the inlet pipe 1544 and the discharge pipe 1512 are arranged in the vertical direction, but the inlet pipe 1544 is disposed on the lower side and the discharge pipe 1512 is disposed on the upper side. Install (150).

According to this, as the water level gradually rises from the bottom to the top, the contact area between the water and the electrode part 1520 expands, so that the efficiency of generating sterilizing water according to the chemical reaction between the electrode part 1520 and the water can be increased.

Inside the casing 1510, a flow path through which water can flow is formed along the longitudinal direction of the casing 1510.

Inside the casing 1510 as described above, two electrode parts 1520 may be disposed to overlap each other. In addition, a spacer 1530 may be provided inside the casing 1510 to maintain a distance between the two electrode parts 1520 .

The electrode part 1520 includes a first electrode 1521 and a second electrode 1522 . One or more holders (not shown) may be provided on an inner surface of the casing 1510 to fix at least a portion of the first electrode 1521 and the second electrode 1522 .

For example, the first electrode 1521 and the second electrode 1522 may be provided in a plate shape.

As another example, the first electrode 1521 may be provided in a plate shape, and the second electrode 1522 may have a folded shape with one side and the other side facing each other. The second electrode 1522 may have a 'U' shaped cross section.

The second electrode 1522 may include a pair of electrode plates 1522a and 1522b facing each other and a bent portion 1522c connecting one side of the electrode plates 1522a and 1522b.

At least one cut-out slit 1522d may be formed in the bent portion 1522a.

The first electrode 1521 may be disposed between the electrode plates 1522a and 1522b.

The electrode plates 1522a and 1522b and the first electrode 1521 are disposed parallel to each other and are spaced apart from each other. That is, a gap G is formed between the electrode plates 1522a and 1522b and the first electrode 1521 .

In addition, in order to maintain the gap G formed between the electrode plates 1522a and 1522b and the first electrode 1521 as described above, between the electrode plates 1522a and 1522b and the first electrode 1521, or the above A space 1530 is inserted between the electrode plates 1522a and 1522b.

A plurality of spacers 1530 may be provided. The spacer 1530 may be inserted into the slit 1522d. For example, two slits 1522d may be spaced apart in the longitudinal direction, and two spacers 1530 may also be provided corresponding to the slits 1522d.

The spacer 1530 includes a central portion 1531 formed parallel to the longitudinal direction of the electrode 1520, and a plurality of protrusions ( 1532) may be included.

For example, the protrusion 1532 may be inserted between the electrode plates 1522a and 1522b to maintain a distance between the electrode plates 1522a and 1522b.

As another example, the protrusion 1532 may be inserted between the electrode plates 1522a and 1522b and the first electrode 1521 to maintain a distance between the electrode plates 1522a and 1522b and the first electrode 1521 .

As described above, when the spacer 1530 is formed of the central portion 1531 and the protrusion 1532, water can flow through the protrusion 1532 while maintaining the distance between the electrodes 1521-1522. , the flow resistance of water can be reduced.

In addition, terminal portions 1523 and 1524 may be formed on the first electrode 1521 and the second electrode 1522, respectively. A gripping portion 1521a formed of a curved surface and protruding to surround at least a portion of the terminal portion 1523 may be formed in the first electrode 1521 .

The terminal portions 1523 and 1524 may pass through the lower cap 1542 and be exposed to the outside. The terminal portions 1523 and 1524 may be formed parallel to each other.

A fitting portion 1513a to which the terminal portions 1523 and 1524 are fixed may be formed on an inner surface of the inlet portion 1513 of the casing 1513 . In addition, a passage hole 1547 through which the terminal parts 1523 and 1524 pass may be formed in the lower cap 1542 . In addition, O-rings 1561 and 1562 may be inserted between the passage hole 1547 and the terminal portions 1523 and 1524 to prevent leakage.

On the other hand, through the terminal parts 1523 and 1524 exposed to the outside of the lower cap 1542, the first electrode 1521 and the second electrode 1522 receive power from the outside and generate water (pure water) in which chlorine ions are dissolved. It is possible to produce hypochlorous acid water having sterilizing power by electrolysis. Due to its characteristics, hypochlorous acid water contains a large amount of air bubbles and comes out cloudy. Therefore, the user can visually check the sterilizing water containing many bubbles and distinguish between purified water and sterilizing water. At this time, the concentration of the sterilizing water may be set within a range that does not cause problems when the user drinks.

In addition, the first electrode 1521 and the second electrode 1522 are disposed to face each other on both sides of the solid polymer electrolyte membrane, and generate high-concentration ozone by inducing an electrolysis reaction in water to generate ozone with strong sterilizing power. This mixed sterilization water can also be produced.

As described above, the terminal portions 1523 and 1524 are provided on the two electrodes 1521 and 1522, respectively, so that external power (current) can be applied to the electrodes 1521 and 1522 through the terminal portions 1523 and 1524. . Each of the terminal portions 1523 and 1524 may protrude in the same direction from one side of the respective electrodes 1521 and 1522 and pass through the lower cap 1542 to protrude outwardly. In addition, the terminal portions 1523 and 1524 may be spaced apart from each other in a horizontal direction (width direction) of the electrodes 1521 and 1522 .

As described above, when the electrode unit 1520 is provided with a flat first electrode 1521 and a folded second electrode 1522,

The size of the electrode unit 1520 is reduced, and as a result, the size of the sterilizing water module 150 may be reduced.

On the other hand, since the second electrode 1522 has a folded shape and the first electrode 1521 is disposed between the electrode plates 1522a and 1522b of the second electrode 1522, the water and the electrodes 1521 and 1522 The contact area can be improved, and furthermore, the chemical reaction between the electrodes 1521 and 1522 and water can be efficiently increased.

For reference, the first electrode 1521 and the second electrode 1522 may be coated on facing surfaces to form a coating layer. For example, the first electrode 1521 and the second electrode 1522 may be formed of a titanium (Ti) material. Also, the coating layer may be formed of a mixture of iridium (Ir) and platinum (Pt). The first electrode 1521 and the second electrode 1522 may have a thickness of 0.5 mm, and the coating layer may have a thickness of 1.6 μm. The coating layer may be formed on both surfaces of the first electrode 1521 . Also, the coating layer may be formed on inner surfaces of the second electrode 1522 facing each other.

The filter bracket 170 may be disposed inside the housing 110 so as to be adjacent to the front cover 113 (see FIG. 1 ) forming the front surface of the housing 110 .

The filter 120 may be coupled to the lower side of the filter bracket 170, and the controller 160 for controlling the sterilizing water module 150 may be coupled to the upper side.

The controller 160 may be detachably coupled to the filter bracket 170 . The controller 160 may include a box-shaped case.

For example, the filter bracket 170 and the control unit 160 may have a screw fastening hole 174 formed at a position facing each other, and the filter bracket 170 and the control unit may be screwed together. At this time, the controller 160 may have a protruding part protruding outward on one side or both sides, and a fastening hole may be formed in the protruding part.

As another example, the filter bracket 170 includes a first extension 171 extending horizontally from an inner surface of the filter bracket 170 and a second extension extending vertically upward from an end of the first extension 171. A first extension protrusion 173 including two extension parts 172 may be formed.

The fourth extension part 172 may support one side of the controller 160 while contacting an upper side of one side surface of the controller 160 .

The first extension projection 173 and the second extension projection 178 may be formed symmetrically on both sides of the filter bracket 170 .

In addition, the filter bracket 170 may be formed with a support protrusion 179 extending toward the front equipped with a front cover 113 (see FIG. 1) to support the lower side of the control unit 160.

Accordingly, the controller 160 may be disposed and coupled to the upper side of the filter bracket 170.

That is, the filter 120 is mounted on the lower side of the filter bracket 170, and the control unit (PCB Assembly, 160) for sending electrical signals to the bacteria count module 150 and the sterilizing water module 150 is installed on the upper side of the filter bracket 170. ) is installed.

While adding a sterilizing water discharge function to an existing water purifier, there is no choice but to place a sterilizing water module 150 that functions to generate sterilizing water and a control unit (PCB Assembly, 160) that gives an electrical signal inside the housing 110.

In the existing water purifier, in order to add the sterilizing water module 150 and the control unit (PCB Assembly, 160) without structurally significant changes, the volume of the sterilizing water module 150 was minimized and a sterilizing water outlet flow path was added.

In addition, as purified water that has passed through the filter 120 passes through the sterilizing water module 150 formed by coating platinum and iridium on electrodes made of titanium inside the sterilizing water module 150, hypochlorous acid is generated while sterilizing water is generated. It can be.

First, referring to FIG. 29 , raw water passes through the filter 120, purified purified water passes through the inflow valve 35 and the flow sensor 36, and then flows into the sterilizing water module 44.

The purified water passing through the sterilizing water module 44 is changed into sterilizing water, and the sterilizing water discharged from the sterilizing water module 44 flows into the second water outlet valve 62 .

Then, according to the open position of the second water outlet valve 62, the sterilized water flowing into the second water outlet valve 62 flows into the water outlet 200 and is supplied to the user through the second water outlet nozzle 220 or , through the drain pipe 50, can be dumped into the drain.

The second water outlet valve 62 is opened and closed by the controller 160. In detail, when the controller 160 instructs to open the first outlet connected to the second water outlet nozzle 220, the second water outlet valve 62 opens the first outlet connected to the second water outlet nozzle 220, The introduced sterilizing water is supplied to the side of the second water outlet nozzle 220.

Meanwhile, as described above, when sterilizing water is generated by electrolyzing purified water through the sterilizing water module 150, hypochlorous acid water remains in the casing 1510 or the electrode part 1520 after the sterilizing water is discharged. And, accordingly, the electrolysis performance may be deteriorated. In addition, problems such as discoloration and corrosion may occur in the sterilizing water module 150, the sterilizing water pipe 34, the second water outlet valve 62, and the second water outlet nozzle 220.

In detail, as shown in Chemical Formula 1 below, a problem arises in that manganese ions (Mn 2+ ) contained in water are quickly precipitated in the form of manganese oxide.

[Formula 1]

HOCl + Mn ^{2 +} + H ₂ O → 2MnO _2(s) + Cl ^- + 3H ⁺

Therefore, after sterilizing water is discharged, washing and draining of the sterilizing water module 150, the sterilizing water pipe 34, and the second water outlet nozzle 220 are required.

30 shows a control method for cleaning the sterilizing water module 150.

Referring to FIG. 30, the method for controlling a water purifier according to the present invention includes receiving a sterilizing water output request and a sterilizing water output capacity from the first input unit and the second input unit, turning on the power to the sterilizing water module, and After the purified water is supplied to the sterilizing water module and the sterilizing water is generated in the sterilizing water module, the sterilizing water in the received water output capacity is discharged through the water outlet nozzle, and the sterilized water in the received water output capacity is discharged, the user In a state in which the display and input means are not operated, the power of the sterilizing water module is cut off and purified water is continuously supplied to the sterilizing water module, the purified water flowing into the sterilizing water module and the sterilizing water pipe is and maintaining an open state of the water extraction valve so that a set capacity is supplied to the user via the water extraction nozzle.

The method may further include flowing residual purified water remaining in the sterilizing water pipe into the drain pipe by switching the water outlet valve after the purified water having the set capacity is discharged.

Referring to FIG. 30 , first, when the user requests the sterilizing water to be dispensed, the sterilizing water can be dispensed (S110).

At this time, the amount of sterilized water discharged once may be automatically set as a reference value.

At this time, the water inlet valve 35 and the sterilizing water valve 44 are opened, and the second water outlet valve 62 blocks the second outlet connected to the drain pipe 50 and connects the second outlet connected to the second water outlet nozzle 220. Exit 1 is open. Then, power is supplied to the sterilizing water module 150.

Accordingly, the purified water that has passed through the filter 120 passes through the sterilizing water module 150, is converted into sterilizing water, and is supplied to the second water outlet nozzle 220, and the user can receive the sterilizing water.

Thereafter, it is determined whether a forced stop command is generated from the user (S120).

In step S120, when forced stop occurs, step S190 of proceeding to drain, which will be described later, proceeds.

On the other hand, in step S120, if forced stop does not occur, the amount of washing water (cumulative pulse value) discharged through the second water extraction nozzle 220 is compared with a preset reference value (washing pulse value). (S130)

In step S130, when the amount of washing water discharged (accumulated pulse value) exceeds the preset reference value (washing pulse value), generation of sterilizing water is stopped, and the purified water introduced into the sterilizing water module 150 is in the form of purified water. supplied to the user. (S140)

At this time, the water inlet valve 35 and the sterilizing water valve 44 are opened, and the second water outlet valve 62 blocks the second outlet connected to the drain pipe 50 and connects the second outlet connected to the second water outlet nozzle 220. Exit 1 is open. Then, power supply to the sterilizing water module 150 is cut off.

Thereafter, it is judged whether or not a forced stop command is generated from the user (S150).

In step S150, when forced stop occurs, step S190 of proceeding to drain, which will be described later, proceeds.

On the other hand, in step S150, if forced stop does not occur, the amount of purified water (accumulated value) discharged through the second water extraction nozzle 220 is compared with a preset target value. (S160)

In the step S160, if the amount of purified water (accumulated pulse value) exceeds the preset target value (target pulse value), the discharge of purified water to the second water outlet nozzle 220 is stopped and the drain proceeds. ( S170)

At this time, the water intake valve 35 and the sterilizing water valve 44 are opened, the second water outlet valve 62 opens the second outlet connected to the drain pipe 50, and the second outlet connected to the second water outlet nozzle 220 is opened. 1 exit is shielded. Then, power supply to the sterilizing water module 150 is cut off.

Then, it is determined whether or not the drain has progressed for a preset reference time (S180).

For example, the reference time may be set to about 10 seconds.

Thereafter, if it is determined that the drain has progressed for the reference time, the drain is stopped (S190).

At this time, the water inlet valve 35 and the sterilizing water valve 44 are also blocked, and the second outlet connected to the drain pipe 50 of the second water outlet valve 62 is also blocked, and the second outlet connected to the second water outlet nozzle 220 is also blocked. Exit 1 is also shielded. And, the power supply to the sterilizing water module 150 is maintained in a cut-off state.

According to the foregoing, after the sterilizing water is discharged, purified water is supplied to the second water outlet nozzle 220, and the piping connecting the sterilizing water module 150 and the second outlet nozzle 220 is washed. , The second water outlet nozzle 220 can also be washed. Accordingly, discoloration of the flow path by MnO 2 can be prevented. In addition, as the drain progresses, residual water from the sterilizing water module 150 and the sterilizing water pipe 44 may be discharged to the drain through the drain pipe 50.

For example, the amount of water discharged per time of the washing water may be set to 120ml, 500ml, or 1000ml.

In addition, when the amount of water discharged once is 120ml, the reference value (pulse value) may be set to 205 and the target value (pulse value) may be set to 248.

In addition, when the amount of water discharged once is 500 ml, the reference value (pulse value) may be 849 and the target value (pulse value) may be set to 999.

In addition, when the amount of water discharged once is 1000 ml, the reference value (pulse value) may be 1848 and the target value (pulse value) may be set to 1998.

Although not shown, the sterilizing water module 150 flows the purified water that has passed through the filter from the sterilizing water module 150 to the drain pipe 50 after the drain process, and directs current to the respective electrodes 1521 and 1522. Reliability of the electrodes 1521 and 1522 may be secured by additionally proceeding with a reversal step of applying the reverse. In addition, after the inversion step is performed, an additional drain may be selectively performed.

31 shows a control method for drain.

Referring to FIG. 31, first, the drain proceeds. (S210)

The drain as described above may be performed by a user's manipulation or may be automatically performed.

In the latter case, it is a case where the amount (accumulated value) of washing water and purified water discharged through the second water outlet nozzle 220 exceeds a preset target value. stops, and the drain proceeds automatically.

In step S210, the water inlet valve 35 and the sterilizing water valve 44 are opened, the second water outlet valve 62 opens the second outlet connected to the drain pipe 50, and the second outlet nozzle 220 and The connected first outlet is shielded. Then, power supply to the sterilizing water module 150 is cut off.

In the process of draining as described above, the control unit determines whether there is a request for cold water, hot water, or purified water from the user. (S220)

If, in step S220, it is determined that a command for dispensing cold water, hot water, or purified water has occurred from the user, the drain is stopped (S250).

Then, cold water, hot water, or purified water is dispensed according to the user's request (S260).

On the other hand, in step S220, if a command for dispensing cold water, hot water, or purified water by the user does not occur, it is determined whether the drain has progressed for a predetermined reference time (S230).

For example, the reference time may be set to about 10 seconds.

Thereafter, if it is determined that the drain has progressed for the reference time, the drain is stopped (S240).

At this time, the water inlet valve 35 and the sterilizing water valve 44 are also blocked, and the second outlet connected to the drain pipe 50 of the second water outlet valve 62 is also blocked, and the second outlet connected to the second water outlet nozzle 220 is also blocked. Exit 1 is also shielded. And, the power supply to the sterilizing water module 150 is maintained in a cut-off state.

According to the foregoing, if a request for cold/hot/clean water extraction occurs from the user during the process of draining, the drain is stopped so that cold/hot/purified water extraction immediately proceeds at the user's request. Therefore, the user Regardless of whether it is drained or not, it is possible to immediately receive purified water at a desired temperature, and accordingly, a sense of satisfaction felt by the user can be increased.

32 is a timing diagram showing the operating state of the sterilizing water module and each valve when the sterilizing water is dispensed in a fixed amount. 33 is a timing diagram showing the operation state of the sterilizing water module and each valve before the fixed amount of sterilizing water is discharged and at the time of forced termination. FIG. 34 is a timing diagram showing the operation state of the sterilizing water module and each valve before the quantitative sterilizing water is dispensed and when cold/hot/clean water is dispensed.

First, referring to FIG. 32 , when the sterilizing water is discharged in a fixed amount, when the sterilizing water is completely discharged, it can be confirmed that the purified water is discharged and the pipe cleaning proceeds.

In detail, when a user requests the discharge of sterilizing water, power is supplied (on) to the sterilizing water module 150, and the inlet valve 35 and the sterilizing water valve 44 are opened (on). Also, the first outlet of the second water outlet valve 62 connected to the second water outlet nozzle 220 is turned on.

Then, when the sterilizing water is discharged in a fixed amount, the sterilizing water is discharged, and purified water is discharged through the second water outlet nozzle 220, and the pipe between the sterilizing water module 150 and the second outlet nozzle 220 is washed. In this process, the second water outlet nozzle 220 is also washed. At this time, the power to the sterilizing water module 150 is cut off (off), and the inlet valve 35 and the sterilizing water valve 44 remain open (on). And, the second water outlet valve 62 maintains a state in which the first outlet connected to the second water outlet nozzle 220 is open (on). For example, the time during which purified water is discharged through the second water extraction nozzle 220 as described above may be set to 5 seconds.

As described above, after sterilized water is discharged through the second water outlet nozzle 220, after purified water is discharged, the user uses the sterilized water to wash fruits, vegetables, dishes, etc., and then uses purified water to wash fruits, vegetables, dishes, etc. You can easily rinse the sterilizing water on the object to be washed on the back.

As described above, when the purified water outlet through the second water outlet nozzle 220 is completed, the drain is started. In this process, residual water from the sterilizing water module 150 and the sterilizing water pipe 34 may be discharged through the drain passage 50 . At this time, the sterilizing water module 150 maintains a state in which the power is cut off (off), and the inlet valve 35 and the sterilizing water valve 44 maintain an open state (on). And, the second water outlet valve 62 closes the first outlet connected to the second water outlet nozzle 220 and opens the second outlet connected to the drain pipe 50. For example, as described above, the time during which purified water is discharged through the drain pipe 50 may be set to 10 seconds.

Then, when the drain is completed, the standby mode is entered. In the standby mode, the sterilizing water module 150 maintains a power off state, and the inlet valve 35 and the sterilizing water valve 44 are closed.

32, when the first outlet of the second water outlet valve 62 is open, it means that the second outlet is blocked, and conversely, when the second outlet of the second water outlet valve 62 is open, the first outlet It can mean blocked.

That is, when water is supplied from the second water outlet valve 62 to the second water outlet nozzle 220, the discharge of water to the drain pipe 50 is blocked, and from the second water outlet valve 62, the drain pipe 50 When water is supplied to the side, it can be understood that the discharge of water to the second water outlet nozzle 220 is blocked.

On the other hand, referring to FIG. 33 , it can be confirmed that the drain proceeds immediately when a forced termination is requested from the user before the quantitative discharge of sterilizing water is completed.

In detail, when a user requests the discharge of sterilizing water, power is supplied (on) to the sterilizing water module 150, and the inlet valve 35 and the sterilizing water valve 44 are opened (on). Also, the first outlet of the second water outlet valve 62 connected to the second water outlet nozzle 220 is turned on.

And, before the sterilizing water is discharged in a fixed amount, a request for forced termination of the sterilizing water occurs. As described above, when forced termination is input, the sterilizing water outlet ends and the drain immediately starts.

In this process, residual water from the sterilizing water module 150 and the sterilizing water pipe 34 may be discharged through the drain passage 50 . At this time, the power of the sterilizing water module 150 is turned off, and the inflow valve 35 and the sterilizing water valve 44 remain open (on). And, the second water outlet valve 62 closes the first outlet connected to the second water outlet nozzle 220 and opens the second outlet connected to the drain pipe 50. For example, as described above, the time during which purified water is discharged through the drain pipe 50 may be set to 10 seconds.

Then, when the drain is completed, the standby mode is entered. In the standby mode, the sterilizing water module 150 maintains a power off state, and the inlet valve 35 and the sterilizing water valve 44 are closed.

33, when the first outlet of the second water outlet valve 62 is open, the second outlet is blocked, and conversely, when the second outlet of the second water outlet valve 62 is open, the first outlet is blocked. can be understood

That is, when water is supplied from the second water outlet valve 62 to the second water outlet nozzle 220, the discharge of water to the drain pipe 50 is blocked, and from the second water outlet valve 62, the drain pipe 50 When water is supplied to the side, it can be understood that the discharge of water to the second water outlet nozzle 220 is blocked.

According to the foregoing, when the sterilizing water is not discharged in a fixed amount, the drain is immediately performed, and only when the sterilizing water is discharged in a fixed amount, the first washing is performed while supplying purified water to the second water outlet nozzle 220, and the first When washing is finished, draining can proceed.

When the drain does not proceed for the set time and is forcibly terminated due to a request for cold/hot/clean water discharge, there is an advantage in that the pipe cleaning can be reliably progressed while the drain proceeds again after cold/hot/purified water discharge.

On the other hand, referring to FIG. 34 , when cold/hot/clean water extraction is requested while the drain is in progress, it can be seen that the drain is stopped, cold/hot/clean water is discharged, and then the drain is resumed.

In detail, when a user requests the discharge of sterilizing water, power is supplied (on) to the sterilizing water module 150, and the inlet valve 35 and the sterilizing water valve 44 are opened (on). Also, the first outlet of the second water outlet valve 62 connected to the second water outlet nozzle 220 is turned on.

And, before the sterilizing water is discharged in a fixed amount, a request for forced termination of the sterilizing water occurs. As described above, when forced termination is input, the sterilizing water outlet ends and the drain immediately starts.

In this process, residual water from the sterilizing water module 150 and the sterilizing water pipe 34 may be discharged through the drain passage 50 . At this time, the power of the sterilizing water module 150 is turned off, and the inflow valve 35 and the sterilizing water valve 44 remain open (on). And, the second water outlet valve 62 closes the first outlet connected to the second water outlet nozzle 220 and opens the second outlet connected to the drain pipe 50. For example, as described above, the time during which purified water is discharged through the drain pipe 50 may be set to 10 seconds.

As described above, in the process of draining, cold/hot/purified water is requested from the user before the drain is finished.

As described above, when cold/hot/purified water is input, the drain is terminated, and cold/hot/clean water is immediately proceeded. In the process of dispensing cold/hot/clean water, the first water outlet valve 61 opens the first outlet connected to the first water outlet nozzle 210.

Also, the sterilizing water valve 44 is closed, and the inlet valve 35 remains open.

In addition, when the cold/hot/purified water is discharged at a fixed rate, the cold/hot/purified water discharge ends. To terminate cold/hot/clean water output as described above, the first water outlet valve 61 blocks the first outlet connected to the first water outlet nozzle 210 and opens the second outlet connected to the drain pipe 50. can do.

Then, the drain proceeds again.

At this time, the power of the sterilizing water module 150 is turned off, and the inflow valve 35 and the sterilizing water valve 44 remain open (on). Further, the second water outlet valve 62 closes the first outlet connected to the second water outlet nozzle 220 and maintains a state in which the second outlet connected to the drain pipe 50 is open (on). For example, as described above, the time during which purified water is discharged through the drain pipe 50 may be set to 10 seconds.

Then, when the drain is completed, the standby mode is entered. In the standby mode, the sterilizing water module 150 maintains a power off state, and the inlet valve 35 and the sterilizing water valve 44 are closed.

In FIG. 34, when the first outlet of the first water outlet valve 61 is opened, the second outlet is blocked, and conversely, when the second outlet of the first water outlet valve 61 is opened, the first outlet is blocked. can be understood

That is, when water is supplied from the first water outlet valve 61 to the first water outlet nozzle 210, the discharge of water to the drain pipe 50 is blocked, and from the first water outlet valve 61, the drain pipe 50 When water is supplied to the side, it may be understood that the discharge of water to the first water outlet nozzle 210 is blocked.

In addition, it will be understood that when the first outlet of the second water outlet valve 62 is opened, the second outlet is blocked, and conversely, when the second outlet of the second water outlet valve 62 is opened, the first outlet is blocked. can

That is, when water is supplied from the second water outlet valve 62 to the second water outlet nozzle 220, the discharge of water to the drain pipe 50 is blocked, and from the second water outlet valve 62, the drain pipe 50 When water is supplied to the side, it can be understood that the discharge of water to the second water outlet nozzle 220 is blocked.

According to the above, when the drain does not proceed for the set time and is forcibly terminated due to a request for cold/hot/clean water extraction, the drain resumes after the cold/hot/purified water is discharged, and the pipe cleaning can surely proceed. there is.

<Hot water output control>

35 is a flowchart showing a control method for hot water dispensing of a water dispensing device according to an embodiment of the present invention. 36 is a flowchart showing a control method for hot water dispensing of a water dispensing device according to another embodiment of the present invention.

Referring to FIG. 35 , a process of dispensing hot water when the hot water dispensed is ‘first cup’ will be described.

The criteria for the first cup and repeated cups can be set in various ways.

For example, the first cup and the repeated cup may be determined according to whether a waiting time has elapsed after the 'n-1st' hot water extraction when the 'nth' hot water extraction command is input. When the waiting time elapses about 3 minutes, it can be determined as the first cup.

As another example, the first cup and repeated cups may be determined according to the temperature of the hot water in the hot water tank or the remaining water detected by the first water outlet valve 61 .

As another example, the first half and the repeated cups may be determined by the difference between the temperature of purified water flowing into the hot water tank and the temperature of the remaining water detected by the first water outlet valve 61 .

As another example, the first half and repeated cups may be determined by the difference between the temperature of the hot water detected in the hot water tank and the temperature of the remaining water detected by the first water outlet valve 61 .

First, while the user presses the water extraction button 240, a hot water extraction command is input (S301).

Then, whether it is the first cup or repeated cup is judged, and if it is the first cup, preheating proceeds immediately (S302).

In the preheating state, the first water outlet valve 61, the inlet valve 35, and the hot water valve 43 maintain a closed state (S303, S304, S305).

However, the outlet connected to the first water outlet nozzle 210 of the first water outlet valve 61 may remain closed, and the outlet connected to the drain side may remain open.

After the preheating is finished, the preset fixed output is supplied to the hot water tank 130, and real-time temperature control is performed (S306).

For example, in step S306, the output of a working coil (not shown) for heating the hot water tank 130 may be kept constant.

As another example, in step S306, the output of a working coil (not shown) for heating the hot water tank 130 may be adjusted in real time. In detail, factors such as the temperature of the hot water tank 130 or the temperature of hot water heated in the hot water tank 130 or the temperature of purified water flowing into the hot water tank 130 or the flow rate of purified water flowing into the hot water tank 130 in real time It is possible to detect and adjust the output of a working coil (not shown) for heating the hot water tank 130 according to each factor.

The preheating process as described above may be performed in the range of about 4.2 seconds to about 5.0 seconds.

Then, the inflow valve 35 and the hot water valve 43 are opened sequentially. (S307, S308)

Then, draining of residual water and/or hot water in the pipe starts. (S309)

When hot water is drained, the drain-side outlet of the first water outlet valve 61 is opened.

The drain time can be set in various ways. For example, draining may proceed for about 3.6 seconds.

When the drain is completed, hot water is discharged through the first water discharge nozzle 210 .

For hot water dispensing, the drain side of the first water dispensing valve 61 is closed, and the outlet connected to the first dispensing nozzle 210 is opened (S310).

Then, after the set amount of hot water is discharged, the hot water discharge is terminated. (S311)

After that, the first water outlet valve 61 is closed. (S312)

Then, the hot water valve 43 and the inflow valve 35 are sequentially closed (S313, S314).

However, the outlet connected to the first water outlet nozzle 210 of the first water outlet valve 61 may remain closed, and the outlet connected to the drain side may remain open.

Hereinafter, with reference to FIG. 36, a process of dispensing hot water when the hot water dispensed is a 'repeated cup' will be described.

The criteria for the first cup and repeated cups can be set in various ways.

For example, the first cup and the repeated cup may be determined according to whether a waiting time has elapsed after the 'n-1st' hot water extraction when the 'nth' hot water extraction command is input. When the waiting time elapses about 3 minutes, it can be determined as the first cup.

As another example, the first cup and repeated cups may be determined according to the temperature of the hot water in the hot water tank or the remaining water detected by the first water outlet valve 61 .

As another example, the first half and the repeated cups may be determined by the difference between the temperature of purified water flowing into the hot water tank and the temperature of the remaining water detected by the first water outlet valve 61 .

As another example, the first half and repeated cups may be determined by the difference between the temperature of the hot water detected in the hot water tank and the temperature of the remaining water detected by the first water outlet valve 61 .

First, while the user presses the water extraction button 240, a hot water extraction command is input. (S401)

Then, preheating proceeds immediately (S402).

Then, in the preheating state, the water outlet temperature is compared with the reference temperature (S403).

Here, 'output temperature' means the temperature of the hot water sensed by the temperature sensor mounted on the first water out valve 61.

For example, the reference temperature may be set to 75°C.

If the water outlet temperature is below the reference temperature (75°C), preheating is performed.

Then, in order to predict the temperature of the hot water tank 130, it is determined whether or not the waiting time has elapsed beyond the reference time after water extraction (S411).

By winning, the meaning of ‘waiting time after exiting water’ means the waiting time after the ‘n-1th’ hot water extraction when the ‘nth’ hot water extraction is in progress.

If, after water extraction, the waiting time does not elapse beyond the reference time (about 3 minutes), the first water extraction valve 61, the inlet valve 35, and the hot water valve 43 remain closed.

In detail, the first water outlet valve 61 is controlled to be closed. (S412)

However, the outlet connected to the first water outlet nozzle 210 of the first water outlet valve 61 may remain closed, and the outlet connected to the drain side may remain open.

Then, the hot water valve 43 is controlled to be closed. (S413)

Then, the inlet valve 35 is controlled to be closed. (S414)

The hot water valve 43 is installed in front of the hot water tank 130 based on the flow of water.

And, even if the hot water valve 43 is closed, when the water boils inside the hot water tank 43, the pressure of the hot water tank 43 increases, and a part of the heated hot water exits the hot water tank 130. can Then, the hot water that escapes is drained through the first water outlet valve 61. And, the temperature of the drained hot water is sensed in real time by a temperature sensor installed on the inlet side of the first water outlet valve 61 .

In addition, even if the waiting time elapses beyond the reference time (about 3 minutes), the first water outlet valve 61, the inlet valve 35, and the hot water valve 43 remain closed.

In detail, the first water outlet valve 61 is controlled to be closed. (S412)

However, the outlet connected to the first water outlet nozzle 210 of the first water outlet valve 61 may remain closed, and the outlet connected to the drain side may remain open.

Then, the hot water valve 43 is controlled to be closed. (S413)

Then, the inlet valve 35 is controlled to be closed. (S414)

Similarly, the hot water valve 43 is installed in front of the hot water tank 130 based on the flow of water.

And, even if the hot water valve 43 is closed, when the water boils inside the hot water tank 43, the pressure of the hot water tank 43 increases, and a part of the heated hot water exits the hot water tank 130. can Then, the hot water that escapes is drained through the first water outlet valve 61. And, the temperature of the drained hot water is sensed in real time by a temperature sensor installed on the inlet side of the first water outlet valve 61 .

Meanwhile, in step S403, when the water outlet temperature exceeds the reference temperature (75° C.), the preheating drain (primary drain) proceeds.

To this end, the hot water valve 43 is controlled to open. (S421)

The hot water valve 43 is installed in front of the hot water tank 130 based on the flow of water.

Then, the inlet valve 35 is controlled to open. (S422)

At this time, the outlet connected to the first water outlet nozzle 210 of the first water outlet valve 61 is closed, and the outlet connected to the drain side remains open.

Therefore, the preheating drain proceeds, and when the set time elapses, the preheating drain is terminated (S423).

Also, in the preheating drain process, the hot water exiting the hot water tank 130 is drained through the first water outlet valve 61 . And, the temperature of the drained hot water is sensed in real time by a temperature sensor installed on the inlet side of the first water outlet valve 61 .

For example, the preheating drain may be performed for about 0.8 seconds to about 1 second.

That is, in step S403, when the outlet temperature exceeds the reference temperature (75 ° C), preheating and draining for about 1 second are performed while opening the hot water valve 43 and the inlet valve 35, and the step S403 In , when the outlet temperature is below the reference temperature (75° C.), only preheating proceeds with the hot water valve 43 and the inflow valve 35 closed.

The 'preheating time' as described above may be performed for about 1.0 seconds to 5.2 seconds.

Thereafter, the preset fixed output is supplied to the hot water tank 130, and real-time temperature control is performed (S430).

That is, after the step S414 or step S423, the preset fixed output is supplied to the hot water tank 130, and real-time temperature control is performed. (S430)

Then, it is judged whether or not the water is going out intermittently (S431).

Whether or not the water is discharged intermittently may be determined according to the determination in step S411.

For example, in step S411, if the waiting time is longer than the reference time after water extraction, it is determined as intermittent water extraction in step S431.

As another example, in step S411, if the waiting time after water extraction is less than the reference time, in step S431, it is determined that the water is not intermittent water extraction but a repeated cup.

In step S431, if it is determined that the water outlet is intermittent, the water outlet temperature detected by the temperature sensor in real time is compared with the second reference temperature (approximately 88° C.) (S432).

On the other hand, in step S431, if it is not determined that the water outlet is intermittent, step S432 is omitted, and step S441, which will be described later, proceeds.

Meanwhile, in step S432, when the real-time water outlet temperature exceeds the second reference temperature (about 88° C.), hot water is discharged.

To this end, first, the hot water valve 43 is opened (S441).

Then, the inlet valve 35 is opened (S442).

Thereafter, hot water is discharged. (S443)

And, for hot water dispensing, the drain side of the first water dispensing valve 61 is closed, and the outlet connected to the first dispensing nozzle 210 is opened (S444).

Then, after the set amount of hot water is discharged, the hot water discharge is terminated. (S461)

Then, the first water outlet valve 61 is closed (S462).

Then, the hot water valve 43 and the inlet valve 35 are sequentially closed (S463, S464).

However, the outlet connected to the first water outlet nozzle 210 of the first water outlet valve 61 may remain closed, and the outlet connected to the drain side may remain open.

Meanwhile, in step S432, when the water outlet temperature is lower than the second reference temperature (about 88° C.), an additional drain is performed before hot water is discharged.

To this end, the hot water valve 43 is controlled to open. (S451)

Then, the inlet valve 35 is controlled to open. (S452)

At this time, the outlet connected to the first water outlet nozzle 210 of the first water outlet valve 61 is closed, and the outlet connected to the drain side remains open.

Therefore, the additional drain proceeds, and when the set time elapses, the additional drain ends. (S453)

When the additional drain ends as described above, the drain side of the first water outlet valve 61 is closed and the outlet connected to the first water outlet nozzle 210 is opened to discharge hot water (S444).

Then, after the set amount of hot water is discharged, the hot water discharge is terminated. (S461)

Then, the first water outlet valve 61 is closed (S462).

Then, the hot water valve 43 and the inlet valve 35 are sequentially closed (S463, S464).

In summary, when the water outlet temperature exceeds 75° C., preheating drain (primary drain) may proceed during the preheating process.

This is to prevent boiling in the hot water tank.

On the other hand, when the water outlet temperature is 75° C. or less, since the possibility of boiling in the hot water tank is low, the preheating drain (primary drain) may be omitted and only preheating may proceed. However, even at this time, a small amount of hot water is drained due to boiling in the hot water tank.

In addition, after preheating, when the temperature of hot water sensed by the first water outlet valve 61, that is, 'output temperature' is 88°C or less, additional drain (secondary drain) may proceed.

On the other hand, after preheating, when the temperature of the hot water sensed by the first water outlet valve 61, that is, 'output temperature' exceeds 88 ° C, the additional drain (secondary drain) is omitted and hot water can be discharged immediately. .

Here, the time of the additional drain (secondary drain) may vary according to the water temperature.

The higher the temperature of the water flowing into the hot water tank, the shorter the additional drain time may be.

For example, when the water temperature flowing into the hot water tank is less than 30° C., the additional drain time may be 9.5 seconds minus the preheating time.

As another example, when the water temperature flowing into the hot water tank is greater than or equal to 30° C. and less than 45° C., the additional drain time may proceed by subtracting the preheating time from 9.0 seconds.

As another example, when the water temperature flowing into the hot water tank is greater than or equal to 45° C. and less than 60° C., the additional drain time may be 5.0 seconds minus the preheating time.

As another example, when the water temperature flowing into the hot water tank is 60° C. or higher, the additional drain time may be omitted.

Although not shown, when a command for dispensing hot water is input at the nth water outlet and cold water is dispensed at the n−1th water outlet, the drain proceeds unconditionally. Here, the drain may proceed within a range in which all remaining water in the passage between the hot water tank and the first water outlet valve 61 can be discharged.

In addition, even when a command for dispensing hot water is input at the nth water outlet and purified water is dispensed at the n−1th water outlet, the drain proceeds unconditionally. Here, the drain may proceed within a range in which all remaining water in the passage between the hot water tank and the first water outlet valve 61 can be discharged.

On the other hand, only when a command for dispensing hot water is input at the nth outlet and hot water is also dispensed at the n−1th outlet, drain proceeds or proceeds directly without draining according to the temperature of the residual water sensed by the first water outlet valve 61. You can proceed with the exit.

In addition, even when a cold water dispensing command is input at the nth water dispensing, draining may proceed unconditionally. Here, the drain may proceed within a range in which all remaining water in the passage between the cold water tank and the first water outlet valve 61 can be discharged.

Hereinafter, another example of a process of dispensing hot water from the water dispensing device according to the present invention will be described.

First, hot water is requested from the user.

Thereafter, it is determined whether or not the reference time has elapsed after the previous water exit.

For example, the reference time may be set to 3 minutes.

If hot water is requested at the n-th water outlet and hot water is discharged at the n-1th water outlet and the elapsed time is longer than the reference time, only preheating is performed without a drain.

That is, if the hot water extraction proceeds in succession and the time between the consecutive hot water extraction is longer than the reference time, it is determined as the first blessing, and only preheating proceeds without drain. The reason that only preheating proceeds without draining is because the boiling phenomenon due to overheating of the hot water tank does not occur.

For example, preheating may be performed for about 1.8 seconds to about 3.9 seconds. The preheating time may vary depending on the target hot water temperature, the water inflow temperature into the hot water tank, the water flow rate, and the output supplied to the hot water tank.

Thereafter, when the preheating is completed, the water outlet temperature is compared with the reference temperature.

As an example, the 'output water temperature' may mean the temperature of residual water detected by the first water extraction valve 61.

As another example, the 'output temperature' may mean the temperature of hot water discharged from the hot water tank.

Here, the reference temperature may be set to about 88°C.

If the water outlet temperature is equal to or higher than the reference temperature, hot water is immediately discharged from the first water outlet nozzle 210 .

Then, when the set time elapses or when hot water of the target flow rate is discharged, the hot water discharge is terminated.

On the other hand, when the water outlet temperature is lower than the reference temperature, the drain proceeds selectively, and then hot water is discharged from the first water outlet nozzle 210 .

At this time, here, the drain time may vary according to the temperature of the water flowing into the hot water tank or the temperature of the hot water tank itself.

The drain time may be shortened as the temperature of the water flowing into the hot water tank or the temperature of the hot water tank itself is higher.

For example, when the temperature of the water flowing into the hot water tank or the temperature of the hot water tank itself is less than 30° C., the drain time may be 8.5 seconds minus the preheating time.

As another example, when the temperature of the water flowing into the hot water tank or the temperature of the hot water tank itself is greater than or equal to 30° C. and less than 45° C., the drain time may proceed by subtracting the preheating time from 8.0 seconds.

As another example, when the temperature of the water flowing into the hot water tank or the temperature of the hot water tank itself is greater than or equal to 45° C. and less than 60° C., the drain time may proceed by subtracting the preheating time from 4.0 seconds.

As another example, when the temperature of the water flowing into the hot water tank or the temperature of the hot water tank itself is 60° C. or higher, the drain time may be omitted. In addition, hot water is immediately discharged from the first water extraction nozzle 210 .

Hereinafter, another example of a process of dispensing hot water from the water dispensing device according to the present invention will be described.

First, hot water is requested from the user.

Thereafter, it is determined whether or not the reference time has elapsed after the previous water exit.

For example, the reference time may be set to 3 minutes.

If hot water is requested at the n-th water outlet and the time elapsed after hot water is discharged at the n-1th water outlet is less than the reference time, draining is performed simultaneously with preheating.

That is, if the hot water extraction proceeds in succession and the time between the consecutive hot water extraction is less than the reference time, it is determined as a repeated cup, and the drain proceeds simultaneously with preheating. The reason why draining is performed simultaneously with preheating is to prevent boiling due to overheating in the hot water tank.

The drain time may be made within 0.6 seconds to 1.8 seconds.

When the draining and preheating are completed, hot water is immediately discharged from the first water dispensing nozzle 210 .

Then, when the set time elapses or when hot water of the target flow rate is discharged, the hot water discharge is terminated.

In the case of the present invention as described above, the temperature sensor is mounted on the first water outlet valve 61 disposed adjacent to the first water outlet nozzle 210 . Accordingly, temperature satisfaction of cold water and hot water discharged through the first water outlet nozzle 210 may be improved.

If the temperature sensor is disposed on the side of the water purifier body installed inside the sink, even if the temperature of hot or cold water is satisfied in the water purifier body, the long pipe connecting the water purifier body inside the sink and the water outlet outside the sink is A temperature change occurs, and as a result, a user may not be supplied with hot water or cold water of a satisfactory temperature.

On the other hand, in the case of the present invention, since the temperature sensor is mounted on the first water outlet valve 61 disposed near the water outlet nozzle through which water is supplied to the user, the user can receive hot or cold water at a desired temperature.

As in the present invention, when a temperature sensor is mounted on the first water outlet valve 61, the temperature sensor detects the temperature of the hot or cold water, and when the detected temperature of the hot or cold water is unsatisfactory, the hot or cold water in the pipe is drained without supplying it to the water outlet nozzle, and hot or cold water is supplied to the outlet nozzle only when the temperature of the hot water or cold water sensed by the temperature sensor is satisfactory. In addition, the distance between the water outlet nozzle and the first water outlet valve 61 is short, and the temperature of the water hardly changes while hot or cold water flows from the first water outlet valve 61 to the outlet nozzle. Even when the water purifier body is disposed inside the sink and the water outlet nozzle is disposed outside the sink, the water outlet nozzle and the water outlet valve 61 are disposed adjacent to each other and a temperature sensor is mounted on the first water outlet valve 61 Due to the structure, the user can be supplied with hot and cold water at a desired temperature.

And, the drain time may be set differently according to the temperature of purified water flowing into the hot water tank.
