The first branching section R1 may be located at a rear end of the first flow sensor 113. [

At this time, the first flow sensor 113 can sense the flow rate of the purified water supplied to the purified water supply unit WP, and the control unit 170, which will be described later, , Hot water, and the like. It is also possible to determine the replacement timing of the filter provided in the filter unit 120 based on the flow rate sensed by the first flow rate sensor 113.

The constant water supply unit WP may be a direct formula that supplies the purified water filtered by the filter unit 120 to the water extracting unit 191 using the pressure of the raw water. Since the water purifier WP does not have a large-capacity tank, it is possible to reduce the size of the water purifier and to reduce the power consumption for keeping the temperature of the water held in the tank constant. In addition, So that the phenomenon of contamination by the proliferation of bacteria in the water contained in the tank can be minimized, thereby providing a sanitary advantage.

The purified water supply unit WP includes a hot water supply unit for supplying filtered water to the filter unit 120 at a normal temperature, a hot water supply unit for heating and supplying purified water filtered at the filter unit 120, And a cold water supply unit for cooling and supplying purified water filtered by the water supply unit.

That is, unlike the conventional hot water tank, the instantaneous heating unit 130 is not configured to receive the hot water at a predetermined temperature, but only when the hot water is extracted, power consumption can be reduced.

At this time, the flow rate of water in the flow rate control valve 131 is controlled through the temperature of the water sensed by the temperature sensor (not shown) installed in the instantaneous heating unit 130 and the flow rate sensed by the first flow rate sensor 113, So that hot water can be extracted at a required temperature. The instantaneous heating unit 130 may be a ruthenox heater, but is not limited thereto.

Further, since the instantaneous heating unit 130 has a structure which is difficult to withstand high pressure, the instantaneous heating unit 130 can be connected to the steam discharge path L5 for safety when the internal pressure rises above the set pressure. The steam discharge passage (L5) prevents external air from flowing into the instantaneous heating unit (130), and when the pressure of the instantaneous heating unit (130) becomes equal to or higher than a set pressure, (133) may be installed. At this time, the check valve 133 is connected to the steam discharge pipe 134.

To this end, the cold water tank 140 may be provided with a cold water circulation unit including a cold water extraction pump 142, a flow path switching valve 143, and a cold water circulating flow path L8.

The flow path switching valve 143 is connected to the cold water circulation flow path L8 and the cold water extraction flow path LC, respectively, and can open and close the respective flow paths during cold water circulation and cold water extraction.

Therefore, during the cold water circulation, the cold water can be circulated through the cold water circulating flow path L8 via the flow path switching valve 143 by the operation of the cold water extraction pump 142. [

The cold water contained in the cold water tank 140 is supplied to the user through the cold water extraction channel LC through the channel switching valve 143 by the operation of the cold water extraction pump 142 to the purified water extracting unit. The cold water tank 140 may be provided with a drain line L9, a drain valve 144 and a drain pipe 145 to drain the water contained in the cold water tank 140 when necessary for cleaning.

Meanwhile, the supply of the cold water is not limited to the operation performed by the operation of the cold water extraction pump 142, and the cold water may be discharged through the rectifier in which the cold water stored therein is discharged by the pressure of the introduced purified water. The direct water cold water tank may be configured to discharge the cold water that has been cooled before the cold water is introduced.

As described above, the cold water cooled by the direct water cold water tank can be supplied to the user through the cold water extraction channel (LC) to the purified water extractor 191.

On the other hand, the purified water introduced into the cold water branch channel L6 can flow into the ice supply channel L10 through the fourth branch R4 for generating and extracting ice, and the ice supply channel L10 can flow into the ice And may be connected to a supply unit (not shown). The ice supply unit (not shown) may be provided inside the cold water tank 140, but it is not limited thereto and may be provided separately from the cold water tank 140.

An ice tray inlet valve 146 connected to the ice supply passage L10 is provided on the other side of the fourth branching section R4 so that the ice tray inlet valve 146 is opened to open the ice supply passage 146 through the ice supply passage L10, (Not shown).

The ice supply unit (not shown) is provided with a cooling unit (not shown) and can cool the purified water contained therein through a cooling unit (not shown) to generate ice.

The cooling unit (not shown) may have the same configuration as the cooling unit (not shown) used to generate cold water, but it is also possible that a separate cooling unit is provided for generating ice.

The ice generated through the cooling unit may be stored in an ice storage unit (not shown) provided in the ice supply unit (not shown), and may be supplied to a user at the request of the user.

Next, the drink supply unit 150 will be described.

Referring to FIG. 9, the purified water in the filter 120 may be supplied to the beverage supply passage L11 through the first branch R1.

Accordingly, the beverage supply unit 150 is configured to generate beverage by heating and pressurizing the purified water that is filtered at the filter unit 120 and branched at the first branching unit R1.

The beverage supply unit 150 includes a beverage extraction unit 160 that generates beverage, a pump 153 that supplies purified water to the beverage extraction unit 160, And a second flow rate sensor 152 for measuring the flow rate of the purified water supplied to the beverage extracting unit 160. [

The beverage supply unit 150 may include a feed valve 151 connected to the beverage supply passage L11 and turned on at the time of extracting the beverage.

The second flow rate sensor 152 measures the flow rate of water supplied to the beverage extraction unit 160 side. The second flow sensor 152 may be configured to be capable of measuring the flow rate even at a low flow rate (for example, 0.1 to 0.6 LPM) in consideration of a small extraction amount of the beverage extraction unit 160. [ That is, since the first flow rate sensor 113 can only measure a high flow rate (for example, about 0.4 to 2.0 LPM), the low flow rate of the drink supply unit 150 can not be measured. Therefore, by providing the second flow sensor 152 capable of sensing a low flow rate separately from the first flow sensor 113, it is possible to accurately measure the amount of the beverage to be extracted from the beverage supply unit 150.

In addition, the pump 153 may be configured as a high-pressure pump to supply water to the beverage extracting unit 160 at a high pressure (for example, 7 to 10 bar). Since the structure of such a high-pressure pump is known, a detailed description thereof will be omitted.

The heater 154 may be configured to heat the inflow water to supply a high temperature (for example, 90 to 95?) Water or steam to the beverage extracting unit 160. The heater 154 may be composed of a high-pressure pump which can stably operate at a pressure of 7 bar or more (for example, 7 to 10 bar) so as to withstand the high pressure by the pump 153 described above. As an example of such a heater 154, a die casting heater can be used.

The die casting heater may include a heat pipe and a flow pipe through which the water flows, and the heat is transferred from the heat generating device to the flow pipe to heat water flowing through the flow pipe. At this time, the heat conductor may be made of a material having high thermal conductivity, such as aluminum, and may be configured to surround the heating element and the flow tube. Such a die casting heater can be stably used in a high pressure environment because a flow tube is mounted inside a die-cast metal (a heat conductor).

However, the heater 154 used in the present invention is not limited to the above-mentioned die casting heater, and various known heaters may be used as long as they can be used in an environment of high pressure (for example, 7 to 10 bar).

The beverage extracting unit 160 may be configured to extract the liquid beverage by supplying hot water of high temperature and high pressure by the pump 153 and the heater 154 to beverage powder such as coffee powder and the like.

At this time, the beverage extracting unit 160 may extract the beverage directly from the beverage powder, but may be configured to extract the beverage using the beverage capsule 165 containing the beverage powder.

12, the beverage extraction unit 160 may be provided with a capsule mounting portion (not shown) in which a beverage capsule 165 such as a coffee capsule is mounted, and a high pressure water ) Can be supplied to extract the liquid coffee. In the present specification, 'water' is supplied to the beverage extracting unit 160 for convenience. However, when water heated by the heater 154 is supplied at a high pressure, it is converted into steam and supplied to the beverage extracting unit 160 . Accordingly, in the present specification including the claims, 'water' supplied to the beverage extracting unit 160 is defined to include steam and may consist of only steam.

An upper puncturing mechanism 161 for puncturing the upper side of the coffee capsule 165 is provided on the upper side of the coffee capsule 165 so that the water pressurized from the pump 153 can be introduced into the coffee capsule 165 . The lower side of the coffee capsule 165 is provided with a lower perforation mechanism 162 for piercing the lower side of the coffee capsule 165 so that the beverage powder such as the coffee powder 169 inside the coffee capsule 165, So that the liquid coffee can be supplied to the user through the perforated portion.

12, the coffee capsule 165 has a structure in which the coffee powder 169 is accommodated in the capsule body 166 and the coffee powder 169 housed in the upper and lower sides, respectively, An upper lid 167 and a lower lid 168 may be provided for protection. However, the coffee capsule 165 used in the present invention is not limited to the structure shown in Fig. 6, and a known capsule in which the coffee powder 169 is accommodated may be used.

The beverage such as coffee produced in the beverage extracting unit 160 may be provided to the user through the beverage extracting unit 192 via the beverage extracting channel LCF.

The lower part of the beverage extracting unit 160 may be provided with a drain hole 156 for discharging residual water or washing water generated in the beverage extracting unit 160. Water dropped from the drain hole 156 is supplied to the water receiving unit 157, Lt; / RTI >

Meanwhile, the extracting unit 190 including the integer extracting unit 191 and the beverage extracting unit 192 described above may be separated as shown in FIG. 7, but may be formed by combining the extracting unit 190 and the extracting unit 190 together.

Meanwhile, the ice water purifier 100 having a beverage extracting function according to an embodiment of the present invention may include a controller 170 for controlling the driving of the beverage supply unit 150.

The control unit 170 can control the driving of the pump 153 based on the flow rate sensed by the second flow sensor 152. [

That is, when the flow rate sensed by the second flow rate sensor 152 is less than the set flow rate, it means that the flow rate of the water to be supplied to the beverage extraction unit 160 is extremely small, It can be determined that a block phenomenon has occurred in the memory 165.

Therefore, when the flow rate sensed by the second flow sensor 152 is less than the set flow rate, the controller 170 may control the driving of the pump 153 to cope with the block phenomenon.

Specifically, when the flow rate detected by the second flow rate sensor 152 is less than the set flow rate, the controller 170 may stop the pump 153 and may restart the pump 153. [

That is, if the driving of the pump 153 is stopped for a predetermined time, the pressure applied to the coffee capsule 165 becomes lower than the pressure before the pump 153 stops. In this state, when the pump 153 is driven again, the pressure applied to the coffee powder 169 fluctuates. As a result, the pressure distribution and the arrangement state of the powder can be changed. Therefore, stable extraction can be performed by eliminating the blocking phenomenon due to the re-driving after the pump 153 is stopped or by forming the flow path in the area where the blocking phenomenon does not occur.

13 and 14, the controller 170 controls the operation of the pump 153 during at least a portion of the time t2a to t2b of the re-excitation voltage application time t2a to t2c of the pump 153. At this time, The second voltage V2 higher than the first voltage V1 applied to the pump 153 can be applied to the pump 153 during the initial operation.

That is, when the voltage applied to the pump 153 at the time of initial driving (t0 to t1) of the pump 153 is the first voltage V1, the pump 153 is stopped for a predetermined period of time (t1 to t2a) The second voltage V2 of the first voltage V1 can be made larger than the first voltage V1. When the second voltage V2 is higher than the first voltage V1, a higher pressure is applied to the coffee capsule 165 than when the first voltage V1 is applied to the pump 153, It becomes easier to solve the blocking phenomenon of the memory 169.

The controller 170 applies the second voltage V2 to the pump 153 for the set time t2a to t2b after the pump 153 is reconnected and then applies the third voltage V3 lower than the second voltage V2 ) For the remaining time t2b to t2c. That is, the controller 170 can eliminate the blocking phenomenon by applying the second voltage V2, which is larger than the first voltage V1, to the pump 153, so that it is not necessary to continuously maintain the second voltage V2, It is possible to supply the third voltage V3 lower than the second voltage V2 after the time t2a to t2b.

At this time, the third voltage V3 may be set to be equal to the first voltage V1 as shown in FIG. 13, or may be set higher than the first voltage V1 as shown in FIG.

On the other hand, there may occur a case where the block phenomenon is not solved even after the pump 153 is stopped and restarted. That is, when the block phenomenon is not solved even after the pump 153 is driven again, the flow rate detected by the second flow rate sensor 152 becomes smaller than the set flow rate.

If the flow rate sensed by the second flow rate sensor 152 is less than the set flow rate, the controller 170 stops the pump 153 for the set time period, 153 may be re-driven. That is, as shown in FIGS. 13 and 14, the controller 170 may restart the pump 153 after a predetermined period of time (t2c to t3a) has elapsed. In this case, the controller 170 also applies the second voltage V2 to the pump 153 for the set time t3a to t3b, and then the second voltage V2 is lower than the second voltage V2 for the remaining time t3b to t3c. 3 voltage V3 can be applied.

On the other hand, if the flow rate sensed by the second flow sensor 152 continues to be smaller than the set flow rate even after the pump 153 is re-driven, the controller 170 continues the re-driving process after the pump 153 is stopped However, if the set flow rate is not reached even when the pump 153 is restarted a predetermined number of times (for example, three times), the waiting time of the user becomes excessively long, and the coffee powder 169 It may be difficult to solve the block phenomenon.

Accordingly, when the number of re-driving of the pump 153 is equal to or greater than the set number of times, the controller 170 can notify the user of the abnormality in the coffee extracting function through the display unit 180. [ Accordingly, the user can take measures such as removing the coffee capsule 165 which is not to be extracted from the beverage extraction unit 160 and mounting the new coffee capsule 165 in the beverage extraction unit 160 or the like. At this time, even when the driving of the pump 153 is stopped, a residual pressure exists in the coffee capsule 165, so that when the user opens the beverage extracting unit 160, a safety accident due to water splashing or the like may occur. It is preferable to include a step of removing the residual pressure inside the coffee capsule 165 through a channel opening connected to the beverage extracting unit 160 when the function abnormality is noticed.

On the other hand, the controller 170 can notify the user of the cleaning time of the beverage extracting unit 160 through the display unit 180.

For example, when a certain period of time has elapsed based on the last time the beverage extracting unit 160 is used, the controller 170 displays a wash notification through the display unit 180 to allow the user to operate the beverage extracting unit 160 To be cleaned.

Even if the beverage can be extracted even in the state that the display unit 180 displays the wash notification, the wash indication of the display unit 180 does not disappear even in this case, and only when the user cleans the beverage extraction unit 160, The indication may disappear.

The ice water purifier 100 having a beverage extracting function according to an embodiment of the present invention may include a cover (not shown) provided in the beverage extracting unit 160 for mounting the coffee capsule 165 in the beverage extracting unit 160 The control unit 170 controls the heater 154 to be preheated.

It is possible to shorten the preheating time of the heater 154 by preheating the heater 154 in conjunction with the opening of the cover (not shown) provided in the beverage extracting unit 160, So that the drink can be supplied to the user more quickly.

In addition, the controller 170 may control the heater 154 to stop preheating if the cover (not shown) provided in the beverage extracting unit 160 is not opened even after a predetermined time has elapsed.

This is to prevent the unnecessary heater 154 from being preheated, because a cover (not shown) provided in the beverage extracting unit 160 may be kept open depending on the user.

On the other hand, the types of beverage capsules such as the coffee capsules 165 may vary, and the extraction amount extracted may be different for each capsule type. For example, in the case of the coffee capsule 165, the extraction amount may be different, such as 35 cc for espresso, 65 cc for Lungo, and 120 cc for Americano.

Accordingly, when the user selects the type of beverage to be extracted through the input unit 185, the extracted amount can be determined.

Therefore, the control unit 170 is configured to drive the pump 153 until the extraction amount sensed through the second flow sensor 152 reaches a setting extraction amount extracted according to the type of beverage according to the user's selection . In this case, since water is supplied to the beverage extracting unit 160 through the beverage supply passage L11 separated from the flow path of the constant supply portion WP, the temperature and pressure of the water supplied to the beverage extracting unit 160 can be optimized There is an advantage that the taste and flavor of beverages such as coffee are excellent.

Meanwhile, the ice water purifier 100 having a beverage extracting function according to an embodiment of the present invention can maintain the temperature of water supplied to the beverage extracting unit 160 constant.

15, the flow path between the heater 154 and the beverage extracting unit 160 is branched into the beverage supply passage L11 and the bypass passage L12 by the fifth branching section R5 And a bypass valve 155 may be provided in the bypass passage L12.

A residual amount may remain in the flow path between the heater 154 and the beverage extracting unit 160 during the beverage extracting process and the temperature of the water supplied to the beverage extracting unit 160 may be lowered due to such residual water.

That is, even if high temperature (for example, 90 to 95?) Of water is supplied to the heater 154, the temperature of the water entering the beverage extracting unit 160 due to the residual water can be lowered.

Therefore, by opening the bypass valve 155 before and / or after the beverage is extracted and discharging the residual water present in the flow path between the heater 154 and the beverage extraction unit 160, the temperature of the water supplied from the heater 154 It is possible to prevent change.

The bypass valve 155 may be connected to the drain port 156 of the beverage extraction unit 160 via the bypass line L12.

Therefore, residual water existing in the flow path between the heater 154 and the beverage extracting unit 160 through the opening of the bypass valve 155 can be discharged to the drain port 156.

Describing in detail the process of discharging the residual water before and / or after the beverage is extracted.

For example, when the user selects the beverage extraction in the case of discharging the residual water before extracting the beverage, the heater 154 provided in the beverage supply unit 150 may be preheated.

At this time, the bypass valve 155 is opened with the preheating of the heater 154. However, the bypass valve 155 is not limited to being opened simultaneously with the preheating of the heater 154, and it is also possible that the bypass valve 155 is opened when the temperature of the heater 154 reaches the set temperature.

The heater 154 can be heated until the temperature of the heater 154 reaches a predetermined temperature (for example, 90 to 95 캜) .

While the pump 153 is being driven, the bypass valve 155 may remain open for a certain period of time.

Therefore, by driving the pump 153, residual water remaining in the flow path between the heater 154 and the beverage extracting unit 160 can be discharged to the outside.

When the predetermined time (for example, two seconds) elapses while the bypass valve 155 is opened during the driving of the pump 153, the bypass valve 155 is closed and the pump 153 is driven High-temperature, high-pressure water is supplied to the beverage extracting unit 160, so that the beverage can be extracted.

When the extraction of the beverage is completed, the driving of the pump 153 can be stopped, and the driving of the beverage supply unit 150 can be terminated.

Next, a process of discharging the residual water after extracting the beverage will be described.

When the user selects beverage extraction, the heater 154 provided in the beverage supply unit 150 can be preheated.

The heater 154 can be heated until the temperature of the heater 154 reaches a predetermined temperature and the pump 153 is driven (for example, .

By driving the pump 153, high-temperature, high-pressure water is supplied to the beverage extracting unit 160 so that the beverage can be extracted.

When the beverage is extracted, the driving of the pump 153 can be stopped, and the bypass valve 155 can be opened.

Even if the driving of the pump 153 is stopped, residual pressure may exist in the inner flow path of the beverage supply unit 150, so that residual water existing in the flow path between the heater 154 and the beverage extraction unit 160 Can be discharged.

When the bypass valve 155 is opened for a predetermined time (for example, two seconds), the bypass valve 155 can be closed and the driving of the beverage supply unit 150 can be terminated .

Next, the process of discharging the residual water before and after the beverage extraction will be described.

The process of discharging the residual water before and after the beverage extraction passes both the process of discharging the residual water before the beverage extraction and the process of discharging the residual water after extracting the beverage.

That is, before the beverage is extracted, the bypass valve 155 is opened and closed for a predetermined time (for example, 2 seconds) during driving of the pump 153, and then the beverage is extracted. The bypass valve 155 is opened and closed for a predetermined time (for example, two seconds) after the driving of the bypass valve 153 is stopped.

Therefore, the discharge of the residual water is performed twice before and after the beverage extraction.

In this way, when the beverage is extracted, the bypass valve 155 is opened to discharge the residual water present in the flow path between the heater 154 and the beverage extraction unit 160, whereby the temperature of the water supplied from the heater 154 changes Can be prevented.

Meanwhile, the ice water purifier 100 having a beverage extracting function according to an embodiment of the present invention can provide a hot beverage or a cold beverage to the user.

As described above, since the beverage is extracted by hot water at high temperature and high pressure, the beverage to be extracted is supplied to the user at a relatively high temperature.

However, in the ice water purifier 100 having a beverage extracting function according to an embodiment of the present invention, beverage extraction such as coffee and ice extraction can be performed at the same time by the user's choice.
