It includes a flow path switching valve 300 to supply or drain outward.

In this case, the first temperature sensor may be installed inside the flow path switching valve 300.

In this embodiment, the flow path switching valve 300 is opened and closed by the valve control unit.

The valve control unit controls the flow path switching valve 300 to drain outward when the hot water introduced into the flow path switching valve 300 is the 'first cup'.

For reference, in the standby mode in which hot water is not discharged, the flow path switching valve 300 may be open to the drain side.

For example, the valve control unit controls the flow path switching valve 300 so that the drain proceeds for a predetermined time when the hot water introduced into the flow path switching valve 300 is the first cup. After the drain is completed, the flow path switching valve 300 is controlled to supply hot water to the water outlet nozzle 210.

As another example, when the hot water introduced into the flow path switching valve 300 is the first cup, the valve controller controls the flow path switching valve 300 to drain until the water temperature detected by the first temperature sensor reaches a reference temperature. do. After the drain is completed, the flow path switching valve 300 is controlled to supply hot water to the water outlet nozzle 210.

On the other hand, the valve control unit controls the flow path switching valve 300 so that hot water is supplied to the water outlet nozzle 210 without draining, when the hot water introduced into the flow path switching valve 300 is a "repeated cup."

In the above description, the meaning of 'first cup' may be defined by various criteria.

For example, after the hot water is discharged to the water extraction nozzle 210, it may be divided into the first glass and the repetitive glass according to the last time. In detail, when the N-th hot water discharge proceeds in the state where the reference time t1 is set, when the reference time t1 elapses after the previous (N-1th) hot water discharge proceeds, it is determined as the first cup. On the other hand, if the reference time (t1) has not passed since the previous (N-1) hot water discharge proceeds, it is determined as a repetitive cup.

As another example, after the operation of the hot water module 70 is finished, it may be divided into a first cup and a repeating cup according to the last time. In detail, when the hot water is discharged while the reference time t2 is set, it is determined as the first cup when the reference time t2 elapses after the operation of the hot water module 70 ends. On the other hand, if the reference time (t2) has not passed after the operation of the hot water module 70 ends, it is determined as a repetitive cup.

As another example, the first glass and the repeating glass may be divided according to the temperature of the water filled in the hot water flow passage 33. In detail, when the hot water is discharged while the reference temperature is set, if the temperature of the water introduced into the hot water flow passage 33 or the flow path switching valve 300 is lower than the reference temperature, it is determined as the first cup. On the other hand, if the temperature of the water introduced into the hot water flow passage 33 or the flow path switching valve 300 is higher than or equal to the reference temperature, it is determined as a repetitive cup.

As another example, the first glass and the repetitive glass may be classified according to the temperature difference of the water filled in the hot water flow passage 33 and the temperature of the water filled in the water discharge passage 30. In detail, when the hot water is discharged while the reference value is set, if the difference between the temperature of the water introduced into the hot water flow passage 33 or the flow path switching valve 300 and the temperature of the water filled in the discharge flow passage 30 is lower than the reference value, Judging by the first cup. On the other hand, if the difference between the temperature of the water introduced into the hot water flow passage 33 or the flow path switching valve 300 and the temperature of the water filled in the water discharge passage 30 is higher than or equal to the reference value, it is determined as a repetitive cup.

In addition, various embodiments may occur as a criterion for distinguishing the first cup and the repeating cup.

In addition, when any one of the first cup definition criteria of the various examples described above is satisfied, it may be determined as the first cup, and it may be determined as the first cup only when a plurality of criteria are satisfied. It may also be determined as the first cup if all the criteria are satisfied.

On the other hand, the facet 200 may be mounted so that the whole is exposed to the upper portion of the sink 10, as shown in FIG. Accordingly, the body 220 having the flow path switching valve 300 embedded therein and the water extraction nozzle 210 extending to the upper portion of the body 220 may be positioned at the top of the sink 10.

As another example, the facet 200 may have a lower portion mounted inside the sink 10. Accordingly, the body 220 in which the flow path switching valve 300 is embedded is disposed inside the sink 10, and the water extraction nozzle 210 extending upward of the body 220 is exposed to the upper side of the sink 10. Can be mounted.

In this embodiment, the flow path switching valve 300 may be provided as a 2-way valve. The flow path switching valve 300 communicates with the inlet connected to the hot water flow passage 33, the inlet, the outlet connected to the outlet nozzle 210 side, the inlet and the drain pipe 23 or drain (not shown) When the body is formed with a drain hole connected to the side and provided inside the body, it may include an opening and closing means for selectively opening and closing the outlet and the drain.

In addition, the facet 200 may be provided with a display and input means 240.

The display and input unit 240 may be provided by a touch screen method.

For example, the display and input unit 240 may be provided on the water extraction nozzle 210. The display and input unit 240 may be provided with hot water, purified water, cold water selection function, withdrawal command function, cold water and hot water temperature setting function, drain selection function, filter replacement cycle notification function.

In addition, the facet 200 may be provided with sterilized water cock 230. In addition, the undersink unit 100 is provided with a sterilizing water generating unit (not shown). Therefore, the sterilizing water generated in the sterilizing water generating unit may be supplied to the outside of the sink 10 through the sterilizing water cock 230.

In addition, the water extraction nozzle 210 and the sterilizing water cock 230 may be rotatably mounted about the body 220.

Hereinafter, with reference to FIG. 2, the process of taking out purified water, cold water and hot water in the water dispensing apparatus according to the present invention will be described.

The undersink unit 100 is connected to the water supply through the raw water pipe 11 to receive the raw water. 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.

Then, the decompressed raw water flows to the filter 60 along the pipe connecting the pressure reducing valve 12 and the filter 60. The raw water passing through the filter 60 is removed to be purified water. 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 detection unit 14 may be connected to the valve control unit 510, and the opening degree of the flow rate control unit 20 may be adjusted according to a signal transmitted from the valve control unit 510. In addition, the flow rate detected by the flow rate sensing unit 14 may be transmitted to the output control unit 520 which will be described later and used as data necessary for output control of the hot water module 70.

On the other hand, the purified water passing through the flow control unit 20 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 outlet valve 18 and the cold water outlet valve 17 may be connected to the valve controller to determine whether the water purification valve 18 and the cold water outlet valve 17 are opened or closed. By the user's setting, the purified water discharge valve 18 and the cold water discharge valve 17 may be selected, and the selected valve may be opened by manipulating the discharge button provided on the outside of the water purifier 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 40. Water flowing along the cooling coil is heat-exchanged with the cooling water inside the cooling tank 40 to be cooled by cold water. To this end, the coolant is cooled to maintain a set temperature.

A compressor connected to the output control unit may be driven to cool the cooling water. The operation of the compressor may be determined by a cold water temperature sensor provided in the cooling tank 40. 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.

Cold water passing through the cooling tank 40 may be taken out through the water outlet pipe 34 and the water outlet nozzle 210.

On the other hand, when the purified water outlet valve 18 is opened, the purified water passing through the purified water pipe 31 and the purified water outlet valve 18 connected to the purified water side of the T connector 16 is discharged water pipe 34 and the outlet nozzle ( It can be taken out through the 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 valve control unit, the water flowing in the hot water pipe 33 through the flow rate control unit 20 flow rate suitable for heating the hot water Can be adjusted. In detail, the valve controller adjusts the amount of purified water supplied to the hot water tank side of the hot water module 70 so that the water is heated to the temperature set in the hot water module 70.

As described above, the purified water passing through the flow controller 20 passes through the hot water module 70. Then, the hot water module 70 can be heated to a set temperature in the process of passing. The hot water module 70 may be heated by an induction heating method, and for this purpose, the output control unit 520 adjusts the output of the working coil included in the hot water module 70.

The purified water passing through the hot water module 70 may be heated to a set temperature.

The hot water heated while passing through the hot water module 70 flows toward the water extraction nozzle 210 along the hot water flow passage 33, and can be taken out through the water discharge pipe 34 and the water discharge nozzle 210. .

The hot water module 70 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 70 to boil to be discharged to the outside. In addition, the safety valve 231 may be provided in the drain pipe 23 so that the safety valve 231 may be opened 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.

Meanwhile, in the water dispensing apparatus according to the present invention, cold water, purified water, and hot water may be extracted to the outside through one water outlet pipe 34 and the water outlet nozzle 210.

As described above, if the cold water, purified water, hot water is withdrawn through one of the water outlet pipe 34, the heat effect is bound to occur.

In detail, when the cold water is discharged after the hot water is discharged, there is a problem that relatively less cold water is discharged to the water extraction nozzle 210 while the temperature of the cold water is increased due to the influence of the hot water.

In addition, when the hot water is discharged after the cold water discharge, there is a problem that relatively less hot (lukewarm) water is discharged to the discharge nozzle 210 while the temperature of the hot water decreases due to the influence of the cold water.

Therefore, even when one water outlet pipe 34 and the water outlet nozzle 210 are used, it is necessary to take measures to ensure that the hot water and the cold water can be discharged to the water extraction nozzle 210 at a satisfactory temperature without the influence of heat between each other. .

In addition, in the case of the undersink water purifier, the water extraction nozzle 210 through which hot water is discharged is installed outside the sink 10, and the hot water module 70 in which the hot water is generated is installed inside the sink. Therefore, the length of the hot water flow passage 33 connecting the hot water module 70 and the water extraction nozzle 210 is long. In the standby mode, the hot water flow passage 33 is filled with hot water.

In this state, if time passes, the hot water filled in the hot water flow passage 33 is forced to cool down while the temperature is lowered due to external influences. And, when the hot water is discharged, the filled equation of the hot water flow passage 33 is discharged to the water extraction nozzle 210, the user has a problem that the hot water of the hot temperature is provided.

According to the present invention, at least a part of the water filled in the long hot water flow passage 33 according to the condition is drained, and the newly generated hot water is supplied to the water extraction nozzle 210 to provide hot water at a temperature satisfactory to the user. have. That is, the hot water temperature of the first cup can be improved, and further, hot water of a desired temperature can be provided.

To this end, the valve control unit 510 determines that the water filled in the hot water flow passage 33 has cooled down when the hot water introduced into the flow path switching valve 300 is the 'first cup', and the flow path switching valve so as to drain outward. Control 300).

For example, the valve control unit 510 controls the flow path switching valve 300 so that the drain proceeds for a predetermined time when the hot water introduced into the flow path switching valve 300 is the first cup. After the drain is completed, the flow path switching valve 300 is controlled to supply hot water to the water outlet nozzle 210. Here, the drain time may proceed until all the water filled in the hot water flow passage is drained.

As another example, when the hot water introduced into the flow path switching valve 300 is the first glass, the valve controller 510 drains the water until the water temperature detected by the first temperature sensor 410 reaches a reference temperature. The valve 300 is controlled. Thereafter, while the temperature condition of the hot water is satisfied, when the drain is completed, the flow path switching valve 300 is controlled to supply the hot water to the water outlet nozzle 210.

On the other hand, when the hot water introduced into the flow path switching valve 300 is a "repeating cup," the valve controller 510 opens the flow path switching valve 300 so that the hot water is supplied to the water outlet nozzle 210 without a separate drain. To control.

Accordingly, there is an advantage that the user is provided with hot water of the desired temperature.

Hereinafter, some components of the present invention will be described in more detail the 'hot water module'.

3 to 4 is a perspective view of a hot water module which is a component of the present invention. And, Figure 5 is an exploded perspective view of a hot water module which is a component of the present invention.

The hot water tank 71 is mounted to the rear of the heating bracket. The hot water tank 71 is made to generate heat under the influence of the magnetic force line formed by the working coil 72. Therefore, the purified water is heated while passing through the internal space of the hot water tank 71 to become hot water.

In addition, the overall shape of the hot water tank 71 may be formed in a flat and compact shape. The hot water tank 71 is formed to correspond to the overall shape of the hot water module 70 so that the hot water tank 71 may be accommodated in a slim space provided in the water dispensing apparatus. In addition, the hot water tank 71 is formed to have a large area, the heating area can be sufficiently secured and instantaneous heating is possible.

The hot water tank 71 is formed by joining a planar first cover 711 and at least a portion of the second cover 712 having a concave-convex shape while making surface contact. In addition, an output tube 713 through which heated water is discharged is formed at an upper end of the hot water tank 71, and an input tube 714 is formed at a lower end or a center of the hot water tank 71 to supply water for heating. do. The output tube 713 extends laterally to have an upward slope, and the input tube 714 extends laterally to have a downward slope. Therefore, the connection space of the pipe connected to the hot water tank 71 is secured, so that the water flows easily.

The output pipe 713 is connected to the hot water flow passage 33 extending to the outlet nozzle 210 side. In addition, the input pipe 714 is connected to the hot water flow passage 33 extending to the filter side.

As shown in the figure, the hot water tank 71 is formed by combining the first cover 711 and the second cover 712. The first cover 711 and the second cover 712 may be coupled to each other by welding or the like to maintain airtightness.

The first cover 711 has a flat plate shape so as to generate heat under the influence of the magnetic force line formed by the working coil 72. The first cover 711 may be made of a suitable material for heat generation. The first cover 711 may be made of a stainless material, and preferably may be made of four series of stainless materials. More preferably, the first cover 711 may be made of STS (Sainless Steel, Korea Industrial Standard) 439 material.

Since the second cover 712 is disposed on the opposite side of the working coil 72 with respect to the first cover 711 and has less influence of the magnetic force line, the second cover 712 has less relationship with heat generation than the first cover 711. Therefore, it is preferable that the second cover 712 is made of a material having corrosion resistance property rather than heat generation property. In addition, an output tube 713 and an input tube 714 are provided at the centers of upper and lower ends of the second cover 712. The output tube 713 and the input tube 714 may extend in opposite directions.

The second cover 712 includes a base surface 7121 and a protrusion 7122 formed in a plane. The base surface 7121 and the protrusion 7122 may be integrally formed by press working. When the second cover 712 having the base surface 7121 is partially pressed, a protrusion 7122 protruding in the opposite direction of the first cover 711 may be formed on the second cover 712.

The base surface 7121 is coupled to the first cover 711 while being in surface contact with the first cover 711. In addition, the protrusion part 7142 protrudes from the base surface 7121 in the opposite direction to the first cover 711, and when the first cover 711 and the second cover 712 are bonded to each other, It is spaced apart from the first cover 711. The circumference of the protrusion 7122 may be inclined or rounded. For example, the cross section of the protrusion part 7142 may be formed in a semi-circle shape or an arc shape.

The protrusion part 7142 is positioned between the input tube 714 and the output tube 713, and may be bent a plurality of times to extend the residence time of water in the hot water tank 71.

The protrusion part 7142 defines a 'heating flow path' through which the purified water passes along with the first cover 711. In the following description, since the heating flow path is defined by the projection portion 7142, and the shape of the heating flow path is determined according to the shape of the projection portion 7122, the projection portion 7122 is called the heating flow path. In other words, the protrusion and the heating passage can be understood as the same concept.

According to the present invention, the purified water introduced into the input pipe 714 is heated while passing through the heating flow path 7122 and discharged to the output pipe 713.

At this time, the purified water flowing into the hot water tank 71 is changed through the heating flow path (7122) of the bent form a plurality of times, the flow direction changes a plurality of times.
