Hereinafter, with reference to FIGS. 1 to 3, a process for discharging purified water, cold water, and hot water in the water dispensing apparatus according to the present invention will be described.

The undersink unit 100 receives raw water through the raw water pipe 11 connected to the water pipe. A pressure reducing valve 12 is installed on the raw water pipe 11, and the raw water passing through the pressure reducing valve 12 is reduced in pressure at a set pressure.

The decompressed raw water flows to the filter 120 along a pipe connecting the pressure reducing valve 12 and the filter 120. The raw water passing through the filter 120 is purified to remove foreign substances. And, by opening the inlet valve 13, the purified water passes through the inflow valve 13 along the water discharge pipe 30 in order to pass through the flow rate sensing unit 14 in order.

In this case, the flow rate detected by the flow rate detection unit 14 may be used as data necessary for output control of the hot water module 130.

On the other hand, the purified water passing through the flow rate sensing unit 14 flows along the water discharge pipe (30). Then, it may be branched to the cold water side and the hot water side through the branch pipe (15).

Further, the purified water branched to the cold water side is branched to the cold water side and the purified water side again by the T connector 16 and flows to the purified water pipe 31 and the cold water pipe 32, respectively. The purified water discharge valve 18 and the cold water discharge valve 17 are respectively installed in the purified water pipe 31 and the cold water pipe 32. The purified water discharge valve 18 and the cold water discharge valve 17 may be selected by a user of the purified water / cold water selection operation, and the selected valve may be opened by operating the user's discharge button to extract purified water or cold water. .

At this time, the water passing through the cold water pipe 32 and the cold water outlet valve 17 connected to the cold water side of the T connector 16 passes through the cooling coil inside the cooling tank 140. Water flowing along the cooling coil is heat-exchanged with the cooling water inside the cooling tank 140 to be cooled by cold water. To this end, the coolant is cooled to maintain a set temperature.

In addition, a compressor may be driven to cool the cooling water. The driving of the compressor may be determined by a cold water temperature sensor provided in the cooling tank 140. Thus, the coolant can always maintain the set temperature, the drive of the compressor can be adjusted for this purpose. The compressor may be adjusted in frequency in response to a load required by the inverter compressor, and the cooling capacity may be adjusted. That is, the compressor can be driven by the inverter control and can cool the cooling water at the optimum efficiency.

On the other hand, the compressor may be set to a force off (off) operation by the user operating the operation unit of the water purifier. It is possible to force the compressor to be in the off state when cold water consumption is low in winter or when power saving is needed, or when cold water is not desired.

The cold water passing through the cooling tank 140 may be extracted to the outside through the connection pipe 40 and the water discharge nozzle 210 connected to the cold water pipe 32.

On the other hand, when the purified water outlet valve 18 is opened, the purified water flowing into the purified water side of the T connector 16 passes through the purified water pipe 31 and the purified water outlet valve 18, and is connected to the purified water pipe 31 It may be taken out through the connection pipe 40 and the water extraction nozzle 210.

On the other hand, when the user selects the hot water withdrawal, the purified water flows to the hot water side of the branch pipe 15, and then flows to the hot water pipe (33).

At this time, the hot water outlet valve 19 and the flow rate control unit 20 are opened by the control of the control unit 150, and the water flowing in the hot water pipe 33 through the flow rate control unit 20 to the heating of the hot water. It can be adjusted to an appropriate flow rate. In detail, the controller 150 adjusts the amount of purified water supplied to the hot water tank side of the hot water module 130 so that the water is heated to the temperature set by the hot water module 130.

As described above, the purified water passing the flow control unit 20 passes through the hot water module 130. Then, the hot water module 130 can be heated to a set temperature in the process of passing. The hot water module 130 may be heated by an induction heating method, and for this purpose, the output controller 520 adjusts the output of the working coil included in the hot water module 130.

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

The hot water heated while passing through the hot water module 130 flows toward the water discharge nozzle 210 along the hot water pipe 33 and is connected to the hot water pipe 33 through a connection pipe 40 and a water discharge nozzle 210. It can be taken out to the outside.

In addition, the hot water module 130 may be further connected to the drain pipe 23. The drain pipe 23 allows the steam generated when the water inside the hot water module 130 to boil to be discharged to the outside. In addition, the safety valve 231 is provided in the drain pipe 23 to open the safety valve 231 to discharge steam to the outside when a pressure higher than a predetermined pressure is generated.

In detail, the safety valve 231 is for discharging steam generated when the hot water is heated in the hot water tank, and prevents the pressure of the inside of the hot water tank from being excessively increased. The safety valve 231 may be configured to open at a set pressure, and may have various structures to smoothly discharge steam in the hot water tank.

Figure 4 is a perspective view showing the top cover and the extraction pipe and the connection pipe. 5 is a longitudinal cross-sectional view of FIG. 4. And, Figure 6, in Figure 4, is a perspective view showing a state in which the protective cap is separated. 7 is an enlarged view of a part of FIG. 6. And, Figure 8 is a plan view showing a state in which the protective cap is removed in FIG.

4 to 8, a pipe hole 112 is formed in the top cover 111 to allow the water outlet pipe 30 to pass therethrough.

In the case of the undersink water purifier, the length of the passage connecting the undersink part 100 and the faucet 200 is reduced, through the top cover 111 to minimize the temperature loss during the supply of hot or cold water, hot and cold water. , Discharge the purified water.

Conventionally, the water discharge pipe 30 was not a structure passing through the pipe hole 112, the water discharge pipe is connected to the lower end of the pipe hole 112, based on the top cover 111, connected to the top of the pipe hole The pipe is connected to form a structure. That is, the discharge pipe is provided on the inside of the housing, the connection pipe is provided on the outside of the housing.

In such a state, if the connection pipe is separated from the top of the top cover 111 for reasons such as replacement of the connection pipe, leakage occurs between them, and the water filled in the connection pipe passes through the housing hole 112. There was a problem flowing into the inside of 110).

In the case of the present invention, in order to solve this leakage problem, the water discharge pipe 30 forms a structure passing through the pipe hole 112.

When the water discharge pipe 30 itself is formed to pass through the pipe hole 112 as described above, even if the connection pipe 40 connected to the water discharge pipe 30 is separated separately, the water flowing out of the connection pipe 40 is a pipe hole Through the 112, a phenomenon that flows into the housing 110 may be prevented.

In detail, in the case of the present invention, the end of the water discharge pipe 30 exposed to the outside of the housing 110 is spaced apart from the pipe hole 112 by a predetermined distance (the length of the water discharge pipe extending to the outside of the pipe hole).

Therefore, even if water leak occurs at the end of the water discharge pipe 30 while separating the connection pipe 40, the leaked water is not introduced through the pipe hole 112.

Here, the water discharge pipe 30 may mean a purified water pipe 31, cold water pipe 32, hot water pipe (33). The connection pipe 40 may include a water connection pipe connected to the purified water pipe 31, a cold water connection pipe connected to the cold water pipe 32, and a hot water connection pipe connected to the hot water pipe 33.

In addition, the water discharge pipe 30 may mean a common pipe (not shown), hot water pipe 33, the cold water and the purified water in common. The connection pipe 40 may include a common connection pipe connected to a common pipe (not shown), and a hot water connection pipe connected to the hot water pipe 33.

The connection pipe 40 is connected to the water discharge pipe 30, and supplies purified water, cold water, hot water received from the water discharge pipe 30 to the faucet 200.

The connection pipe 40 and the water discharge pipe 30 may be connected through a separate connection member 160.

The connecting member 160 may be connected to both ends of the connection pipe 40 and the outlet pipe 30 is formed on each side, the inner passage may be formed in communication with the connector. Therefore, the water in the water outlet pipe 30 may be delivered to the connection pipe 40 through the connection member 160.

In addition, the connection member 160, the water flows from the water discharge pipe 30 to the connection pipe 40, to be provided as a check valve to control the flow of water from the connection pipe 40 to the water discharge pipe 30. Can be.

When the connection member 160 is provided as a check valve as described above, when the connection pipe 40 is separated, a phenomenon in which water from the connection pipe 40 flows into the water discharge pipe 30 may be prevented.

As another example, the connection member 160 may be provided as a check valve that is automatically closed when the outlet pipe 30 or the connection pipe 40 is separated.

According to this, when the connection pipe 40 is separated, the connector that was connected to the connection pipe 40 is automatically closed, the water of the connection pipe 40 is not introduced into the water outlet pipe 30. In addition, it is possible to prevent the phenomenon that the water in the water outlet pipe 30 is leaked to the outside of the connection member 160.

In addition, the top cover 111 is formed to protrude upward from at least one pipe hole 112 formed so that the water discharge pipe 30 penetrates, and an upper surface of the top cover 111, and the pipe hole An outer blocking wall 113 may be formed to be spaced apart from the 112 so as to surround the periphery of the pipe hole 112.

The pipe hole 112 is formed in an inner region of the outer blocking wall 113.

In addition, the connection member 160 may be disposed in an outer region of the outer blocking wall 113. That is, the water discharge pipe 30 and the connection pipe 40 may be connected in the outer region of the outer blocking wall 113.

The outer blocking wall 113 is formed to surround the pipe hole 112. For example, the external blocking wall 113 may be formed in a closed curve shape. As another example, the outer blocking wall 113 may be provided in a rectangular shape with rounded corners.

When the external blocking wall 113 is formed as described above, even if water leakage occurs in the connection member 160 disposed outside the external blocking wall 113, the leaked water is blocked by the external blocking wall 113, Accordingly, the leaked water may be prevented from flowing into the pipe hole 112.

The outer blocking wall 113 may protrude to a uniform height.

In addition, three to four pipe holes 112 may be formed in an inner region of the outer blocking wall 113. Then, through each of the pipe holes 112, the water discharge pipe through which purified water, cold water, hot water, sterilization water and the like may pass.

In addition, the top cover 111 may be formed to protrude upward from an upper surface of the top cover 111, and an internal blocking wall 114 formed along a circumference of the pipe hole 112.

When the inner blocking wall 114 is formed as described above, even if the leakage occurs in the connection member 160 disposed outside the outer blocking wall 113, the leaked water is the outer blocking wall 113 and the inner blocking wall ( It is blocked by the double 114 so that it does not flow into the pipe hole (112).

In addition, even if the leaked water flows beyond the external blocking wall 113, the flow of water is once again restricted by the internal blocking wall 114, so that it does not flow into the pipe hole 112.

In this embodiment, the protrusion height of the inner blocking wall 114 may be higher than the protrusion height of the outer blocking wall 113.

Therefore, even if the leaked water flows over the external blocking wall 113, the flow of water is more restricted by the internal blocking wall 114 formed higher than the external blocking wall 113, and then flows into the pipe hole 112. Will not be.

On the other hand, the water discharge pipe 30 may be bent while passing through the top cover 111.

In detail, the other end portion of the water discharge pipe 30 exposed to the outside of the top cover 111 includes a bent portion 30a that is bent in the horizontal direction in the vertical direction while penetrating the top cover 111.

The water discharge pipe 30 penetrates through the top cover 111 and is bent about 90 ° to the rear and extends backward. Thereafter, the rear end portion 30b is connected to the connection pipe 40 through the connection member 160.

When the water outlet pipe 30 is provided in a shape bent backward, as described above, the connection member 160 may be spaced apart from the pipe hole 112 in the horizontal direction. Therefore, even if the leakage occurs in the connecting member 160, the leaked water is not introduced into the pipe hole 112. In addition, the phenomenon that water leaked by the outer blocking wall 113 and the inner blocking wall 114 flows into the pipe hole 112 can be more surely prevented.
