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

To this end, the beverage supply unit 150 includes a beverage extraction unit 160 for generating a beverage, a pump 153 for pressurizing and supplying purified water to the beverage extraction unit 160 , and purified water to the beverage extraction unit 160 . It may be configured to include a heater 154 for heating and supplying, and a second flow sensor 152 for measuring the flow rate of purified water supplied to the beverage extraction unit 160 .

In addition, the beverage supply unit 150 may include a feed valve 151 that is connected to the beverage supply passage L11 and is turned on when beverage is extracted.

The second flow 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 measure the flow rate even at a low flow rate (for example, 0.1 to 0.6 LPM) in consideration of the small extraction amount of the beverage extraction unit 160 . That is, the above-described first flow sensor 113 cannot measure the low flow rate of the beverage supply unit 150 because only a high flow rate (eg, approximately 0.4 to 2.0 LPM) can be measured. Therefore, it is possible to accurately measure the amount of beverage extracted from the beverage supply unit 150 by installing the second flow rate sensor 152 capable of detecting a low flow rate separately from the first flow rate sensor 113 .

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

And, the heater 154 may be configured to heat the introduced water to supply water or steam of high temperature (eg, 90 to 95?) to the beverage extraction unit 160 . The heater 154 may be configured as a high-pressure pump capable of stably operating at a pressure of 7 bar or more (eg, 7 to 10 bar) to withstand the high pressure caused by the above-described pump 153 . As an example of such a heater 154, a die-casting heater may be used.

The die-casting heater may be configured such that a heating element and a flow tube through which water flows are provided together in a heat conductor, heat is transferred from the heating element to the flow tube, and the water flowing through the flow tube is heated. In this case, the thermal 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. Since the flow tube is mounted inside the die-casting metal (heat conductor), the die-casting heater can be used stably even in a high-pressure environment.

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

And, the beverage extraction unit 160 may be configured to extract a liquid beverage by supplying high-temperature and high-pressure hot water by the pump 153 and the heater 154 to beverage powder such as coffee powder.

At this time, the beverage extraction unit 160 may extract a beverage directly from the beverage powder, but may be configured to extract the beverage using the beverage capsule 165 in which the beverage powder is accommodated.

Referring to FIG. 12 , the beverage extraction unit 160 may include a capsule mounting unit (not shown) in which a beverage capsule 165 such as a coffee capsule is mounted, and high-pressure water (or steam) in the coffee capsule 165 . ) to extract liquid coffee. On the other hand, in the present specification, it is described that 'water' is supplied to the beverage extraction unit 160 for convenience, but when the water heated by the heater 154 is supplied at high pressure, it is changed into steam to be supplied to the beverage extraction unit 160. can Therefore, in the present specification including the claims, 'water' supplied to the beverage extraction unit 160 may include steam, and is defined as may be composed of only steam.

And, the upper side of the coffee capsule 165 is provided with an upper perforating mechanism 161 for perforating 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. . In addition, the lower side of the coffee capsule 165 is provided with a lower perforating mechanism 162 for perforating the lower side of the coffee capsule 165, beverage powder such as coffee powder 169 inside the coffee capsule 165 and high pressure water This contact allows the liquid coffee to be supplied to the user through the perforated portion.

In addition, the coffee capsule 165 has a structure in which the coffee powder 169 is accommodated inside the capsule body 166, as shown as an example in FIG. An upper cover 167 and a lower cover 168 for protection may be provided. 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.

In addition, the beverage, such as coffee, generated by the beverage extraction unit 160 may be provided to the user through the beverage extraction unit 192 through the beverage extraction flow path (LCF).

In addition, a drain port 156 for discharging the residual water or washing water generated in the beverage extraction unit 160 may be provided at the lower portion of the beverage extraction unit 160, and the water falling from the drain hole 156 is a drip tray member 157. can be accepted in

On the other hand, the extraction unit 190 having the above-described purified water extraction unit 191 and beverage extraction unit 192 may be configured separately as shown in FIG. 7 , but it is also possible to be configured as one.

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

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

That is, when the flow rate detected by the second flow rate sensor 152 is less than the set flow rate, it may mean that the flow rate of water supplied to the beverage extraction unit 160 is extremely small or absent, which is a coffee capsule by high pressure water. (165) It can be determined that the blocking phenomenon has occurred inside.

Accordingly, when the flow rate sensed by the second flow rate sensor 152 is less than the set flow rate, the control unit 170 may control the operation of the pump 153 in order to cope with the blocking phenomenon.

Specifically, when the flow rate sensed by the second flow rate sensor 152 is less than the set flow rate, the control unit 170 may stop the pump 153 and then restart the pump 153 .

That is, when the operation of the pump 153 is stopped for a predetermined time, the pressure applied to the coffee capsule 165 is lower than the pressure before the stop of the pump 153 . In this state, when the pump 153 is re-driven, a change occurs in the pressure applied to the coffee powder 169, which makes it possible to change the pressure distribution or arrangement state of the powder. Therefore, stable extraction is possible by eliminating the blocking phenomenon due to the re-driving after stopping the pump 153 or allowing a flow path to be formed in an area where the blocking phenomenon does not occur.

At this time, as shown in FIGS. 13 and 14 , the control unit 170 controls at least a portion of the voltage application time (t2a to t2c) during the re-driving of the pump 153 (t2a to t2b). A second voltage V2 higher than the first voltage V1 applied to the pump 153 during initial driving may be applied to the pump 153 .

That is, when the voltage applied to the pump 153 is the first voltage V1 when the pump 153 is initially driven (t0 to t1), the pump 153 is stopped for a predetermined time (t1 to t2a) and then restarted The second voltage V2 may be greater than the first voltage V1. In this way, when the second voltage (V2) is greater 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, so coffee powder It becomes easier to solve the blocking phenomenon of (169).

In addition, the controller 170 applies the second voltage V2 to the pump 153 for a set time t2a to t2b when the pump 153 is re-driven, and then a third voltage V3 lower than the second voltage V2. ) may be applied for the remaining time (t2b to t2c). That is, the control unit 170 can solve the blocking phenomenon by applying the second voltage (V2) greater than the first voltage (V1) to the pump 153, so there is no need to continuously maintain the second voltage (V2). After time t2a to t2b, a third voltage V3 lower than the second voltage V2 may be supplied.

In this case, the third voltage V3 may be set to be equal to the first voltage V1 as shown in FIG. 13 or set to be higher than the first voltage V1 as shown in FIG. 14 .

On the other hand, there may be a case in which the blocking phenomenon is not resolved even after the pump 153 is stopped and then restarted. That is, when the blockage phenomenon is not resolved even after the pump 153 is re-driven, the flow rate sensed by the second flow rate sensor 152 is less than the set flow rate.

As such, when the control unit 170 restarts the pump 153, when the flow rate sensed by the second flow rate sensor 152 is less than the set flow rate, the control unit 170 stops the pump 153 for a set time and then stops the pump ( 153) may be restarted. That is, as shown in FIGS. 13 and 14 , the control unit 170 may restart the pump 153 after a predetermined period of time (t2c to t3a) has elapsed. Also in this case, the controller 170 applies the second voltage V2 to the pump 153 for the set time t3a to t3b and then for the remaining time t3b to t3c, the second voltage V2 lower than the second voltage V2. 3 voltage V3 may be applied.

On the other hand, if the flow rate sensed by the second flow rate sensor 152 continues to be less than the set flow rate even after the pump 153 is re-driven, the control unit 170 continues to perform the restarting process after the pump 153 is stopped. However, if the set flow rate is not reached even when the pump 153 is re-driven a certain number of times (for example, 3 times), the waiting time for the user becomes excessively long, and the coffee powder 169 ), it may be difficult to solve the blocking phenomenon.

Accordingly, when the number of re-driving of the pump 153 is equal to or greater than the set number, the control unit 170 may notify the user that there is an abnormality in the coffee extraction function through the display unit 180 . Accordingly, the user can take measures such as removing the coffee capsule 165 that cannot be extracted from the beverage extraction unit 160 and mounting a new coffee capsule 165 to the beverage extraction unit 160 . At this time, since residual pressure exists in the coffee capsule 165 even in a state where the operation of the pump 153 is stopped, a safety accident may occur due to water splashes, etc. when the user opens the beverage extraction unit 160, It is preferable to include a process of removing the residual pressure inside the coffee capsule 165 through the opening of the flow path connected to the beverage extraction unit 160, etc., when notifying the malfunction.

Meanwhile, the control unit 170 may notify the user of the washing time of the beverage extraction unit 160 through the display unit 180 .

For example, when a predetermined time has elapsed based on the time when the beverage extraction unit 160 was last used, the control unit 170 displays a washing notification through the display unit 180 to allow the user to select the beverage extraction unit 160 . may be induced to wash.

Even in a state where the washing notification is displayed on the display unit 180, beverage extraction may be possible, but even in this case, the washing notification display on the display unit 180 does not disappear, and the washing notification is only when the user washes the beverage extraction unit 160 The display may disappear.

In addition, in the ice water purifier 100 having a beverage extraction function according to an embodiment of the present invention, a cover (not shown) provided in the beverage extraction unit 160 to mount the coffee capsule 165 to the beverage extraction unit 160 . time), the heater 154 may be controlled to be preheated by the controller 170 .

By preheating the heater 154 in conjunction with the opening of the cover (not shown) provided in the beverage extraction unit 160, the preheating time of the heater 154 can be shortened, and thus the time for extracting the beverage can be shortened. Therefore, it is possible to more quickly supply the beverage to the user.

In addition, the control unit 170 may control to stop the preheating of the heater 154 when the cover (not shown) provided in the beverage extraction unit 160 is opened and does not close even after a preset time elapses.

This is to prevent unnecessary preheating of the heater 154 since there may be cases where the cover (not shown) provided on the beverage extraction unit 160 is kept open depending on the user.

On the other hand, there are various types of capsules for beverages such as coffee capsules 165, and the extraction amount extracted at this time may also be configured differently for each type of capsule. For example, even in the coffee capsule 165, the extraction amount may vary, 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 extraction amount can be determined through this.

Therefore, the control unit 170 is configured to drive the pump 153 until the extraction amount detected through the second flow sensor 152 reaches a set extraction amount extracted according to the type of beverage selected by the user. can In this case, since water is supplied to the beverage extraction unit 160 through the beverage supply passage L11 separated from the flow path of the purified water supply unit WP, the temperature and pressure of the water supplied to the beverage extraction unit 160 can be optimized. There is an advantage in that the taste and aroma of beverages such as coffee are excellent.

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

To this end, referring to FIG. 15 , the flow path between the heater 154 and the beverage extraction unit 160 is branched into the beverage supply flow path L11 and the bypass flow path L12 by the fifth branch R5, and , a bypass valve 155 may be provided in the bypass flow path L12 .

Residual water may remain in the flow path between the heater 154 and the beverage extraction unit 160 in the extraction process of the beverage, and there is a fear that the temperature of the water supplied to the beverage extraction unit 160 may be lowered by the remaining water.

That is, even if the heater 154 supplies high-temperature (eg, 90 to 95?) water, the temperature of the water entering the beverage extraction unit 160 may be lowered by the residual water.

Therefore, the temperature of the water supplied from the heater 154 by opening the bypass valve 155 before and/or after the extraction of the beverage to discharge the residual water present in the flow path between the heater 154 and the beverage extraction unit 160 is change can be prevented.

The bypass valve 155 may be connected to the drain port 156 of the beverage extraction unit 160 through the bypass flow path L12.

Accordingly, the residual water present in the flow path between the heater 154 and the beverage extraction unit 160 through the opening of the bypass valve 155 may be discharged to the drain port 156 .

The process of discharging the residual water before and/or after brewing the beverage will be described in more detail.

For example, if the user selects beverage extraction in the case of discharging the remaining water prior to beverage extraction, the heater 154 provided in the beverage supply unit 150 may be preheated.

At this time, the bypass valve 155 is opened together 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 may be opened when the temperature of the heater 154 reaches the set temperature.

The heater 154 may be heated until it reaches a temperature sufficient for extraction of the beverage (eg, 90 to 95 ℃), and when the temperature of the heater 154 reaches a preset temperature, the pump 153 is driven can be

While the pump 153 is being driven, the bypass valve 155 may maintain an open state for a predetermined time.

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

When a preset time (for example, 2 seconds) elapses while the bypass valve 155 is opened while the pump 153 is being driven, the bypass valve 155 is closed and the pump 153 is closed. By this, high-temperature, high-pressure water is supplied to the beverage extraction unit 160 so that the beverage can be extracted.

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

The heater 154 may be heated until it reaches a temperature sufficient for extraction of the beverage (eg, 90 to 95?), and when the temperature of the heater 154 reaches a preset temperature, the pump 153 is driven can be

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

When the extraction of the beverage is completed, the driving of the pump 153 may be stopped, and the bypass valve 155 may be opened.

Even if the drive of the pump 153 is stopped, since residual pressure may exist in the internal flow path of the beverage supply unit 150, the residual water existing in the flow path between the heater 154 and the beverage extraction unit 160 by the residual pressure is discharged to the outside. can be emitted.

When a preset time (eg, 2 seconds) has elapsed in the open state of the bypass valve 155 , the bypass valve 155 may be closed, and the driving of the beverage supply unit 150 may be terminated. .

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

The process of discharging the residual water before and after extracting the beverage goes through both the process of discharging the residual water before extracting the beverage and the process of discharging the residual water after extracting the beverage.

That is, before beverage extraction, the bypass valve 155 is opened and closed for a preset time (eg, 2 seconds) during the operation of the pump 153, and then beverage extraction is made, beverage extraction is terminated, and the pump After the operation of 153 is stopped, the bypass valve 155 is opened and closed for a preset time (eg, 2 seconds).

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

In this way, the temperature of the water supplied from the heater 154 changes by opening the bypass valve 155 in the beverage extraction process to discharge the residual water present in the flow path between the heater 154 and the beverage extraction unit 160 . can be prevented from doing

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

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

However, in the ice water purifier 100 having a beverage extraction function according to an embodiment of the present invention, extraction of beverages such as coffee and extraction of ice may be simultaneously performed by a user's selection.
