Description

[0001] The present invention relates to an ice water purifier having a beverage extracting function,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice water purifier having a beverage extracting function, and more particularly, to an ice water purifier having a beverage extracting function capable of supplying beverage from a powdered coffee, cocoa, or tea.

As everyday and social life advances and specializes, various devices that can be simply and efficiently used and utilized in life have been developed in great numbers, and a coffee extracting device such as a coffee maker is one of the devices that can be used simply and effectively in daily life.

Such a coffee extracting apparatus is an apparatus for producing a liquid beverage from a capsule containing coffee and powder such as black tea and cocoa. The coffee extracting apparatus supplies high-temperature and high-pressure water (steam) to a capsule loaded in a capsule extracting unit The liquid beverage is extracted.

Recently, there has been developed a coffee purifier which is provided with a coffee extracting device in a water purifier so that a user can take a drink such as coffee as well as purified water.

A conventional coffee water purifier supplies hot water stored in a hot water tank installed in a water purifier to a coffee extracting unit to provide coffee.

The conventional coffee purifier is a hot water tank (not shown), although a significant factor that determines the taste and aroma of coffee extracted from the coffee extraction unit is a constant pressure (e.g., 7 to 10 Bar) and a suitable temperature The temperature of the water supplied to the coffee extracting unit is dependent on the temperature of the hot water contained in the hot water tank, so that there is a problem that the taste and flavor are not constant and the best quality can not be guaranteed.

In addition, the conventional coffee purifier has a problem in that a large capacity storage tank is provided to limit the miniaturization and a large amount of power is consumed to maintain the temperature of the cold water tank and the hot water tank.

On the other hand, when a high-pressure water (steam) is supplied to the coffee powder contained in the capsule, the conventional coffee purifier using the capsule may block the powder to be compressed at a high pressure, so that coffee extraction is sometimes impossible. That is, the coffee powder contained in the coffee capsules is blocked at a high pressure during the extraction to cut off the extraction path. In such a case, coffee extraction is not performed even though the high-pressure pump is operated. In such a block situation, there is a problem that a high pressure pump may fail due to an excessive load applied to the high pressure pump, and a coffee capsule (capsule coffee) which can not be extracted may be discarded.

Further, since the coffee extracted from the coffee extraction unit has a relatively high temperature (for example, 90 to 95 DEG C), it is difficult to drink coffee at various temperatures (for example, cold coffee or hot coffee).

The filter unit 120 may include a sediment filter, a pre-carbon filter, a reverse osmosis membrane filter, a hollow fiber membrane filter, and a post-carbon filter for sequentially purifying raw water. However, the type, number and order of the filters can be changed according to filtration performance required for the water purifier. The filters constituting the filter unit 120 are not limited to the independent cartridges. The first filter 121 and the second filter 122, which are composed of a composite filter as shown in FIG. 1, .

The raw water flowing through the raw water inflow passage L1 is filtered while passing through the filter section 120 provided in the filter medium passage L2.

Meanwhile, the raw water inflow passage L1 may be provided with a pressure reducing valve 111 for reducing the pressure of raw water to a predetermined level or less and a normally open solenoid (NOS) valve 112 for maintaining the normally open state .

As described above, the purified water in the filter unit 120 flows through the first flow rate sensor 113, the flow paths L3, L4, and L6 branched from the first branching unit R1 and provided to the purified water supply unit WP, And is supplied to the flow path L11 provided in the beverage supply unit 150. [

The first branching part R1 is positioned at the rear end of the first flow sensor 113. [

The control unit 170 detects the flow rate of the purified water supplied to the purified water supply unit WP and controls the first flow rate sensor 113 and the second flow rate sensor 113 based on the flow rate sensed by the first flow rate sensor 113, And so on. In addition, it is also possible to determine the replacement time of the filter provided in the filter unit 120 based on the flow rate sensed by the first flow rate sensor 113.

The purified water supplier WP may be configured to supply the purified water filtered by the filter unit 120 to the water extracting unit 191 under 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.

Specifically, the purified water supply unit WP includes a hot water supply unit for supplying purified water filtered at the filter unit 120 to a room 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 filter unit 120, but it is also possible to provide only a part of them.

At this time, the hot water is discharged to the purified water extracting unit 191 through the hot water extracting line LH by opening the hot water extracting valve 132.

On the other hand, the instantaneous heating unit 130 is configured such that the purified water introduced by the opening of the hot water extraction valve 132 is instantaneously heated and discharged. 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 hot water extraction is performed, 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, Thus, hot water at a required temperature can be extracted. 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. When the check valve 133 is opened, the steam discharged to the steam discharge line L5 flows to the outside through the steam discharge pipe 134 .

2, the cold water supply unit is configured such that the purified water supplied from the first branching unit R1 flows through the second branching unit R2 and the third branching unit R3, And the purified water introduced into the cold water branch passage L6 flows into the cold water supply passage L7 through the fourth branch R4 and the cold water supply passage L7 And may be connected to the cold water tank 140.

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 passage switching valve 143 is connected to the cold water circulation passage L8 and the cold water extraction passage LC and opens and closes the respective flow paths during cold water circulation and cold water extraction.

Accordingly, during the cold water circulation, the cold water is circulated through the cold water circulating flow path L8 through the flow path switching valve 143 by the operation of the cold water extraction pump 142. [

The cold water stored in the cold water tank 140 is supplied to the purified water extracting unit through the cold water extracting channel LC via the channel switching valve 143 by the operation of the cold water extracting pump 142, Lt; / RTI > The cold water tank 140 may be provided with a drain passage L9, a drain valve 144 and a drain pipe 145 to drain water contained in the cold water tank 140 when necessary for cleaning.

The supply of the cold water is not limited to the operation of the cold water extraction pump 142, and it may be a direct-current type in which the cold water stored therein is discharged by the pressure of the introduced purified water. The direct water cold water tank is configured to discharge 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 is supplied to the water extracting unit 191 through the cold water extraction channel LC, and is provided to the user.

On the other hand, the purified water flowing 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 purified water flowing into the ice supply channel L10, May be connected to an ice supply (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 branch R4 to open the ice supply passage L10 by opening the ice tray inlet valve 146, The purified water is supplied to the ice supplying unit (not shown).

The ice supply unit (not shown) is provided with a cooling unit (not shown) to cool the purified water stored therein through the 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 generated ice is stored in an ice storage unit (not shown) provided in the ice supply unit (not shown), and is supplied to the user when requested by the user.

Next, the drink supply unit 150 will be described.

Referring to FIG. 3, the purified water filtered in the filter unit 120 is supplied to the beverage supply passage L11 through the first branching unit R1.

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

The beverage supply unit 150 includes a beverage extraction unit 160 for generating a beverage, a pump 153 for supplying 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. In this case,

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, the second flow rate sensor 152, which can be sensed at a low flow rate, is provided separately from the first flow rate sensor 113, so that the amount of the beverage to be extracted from the beverage supply unit 150 can be accurately measured.

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, detailed description thereof will be omitted.

The heater 154 is configured to heat the inflow water to supply a high temperature (for example, 90 to 95 ° C) water or steam to the beverage extracting unit 160. The heater 154 is preferably 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.

In the die casting heater, a heat pipe and a flow pipe through which water flows are provided together in the heat conductor, and heat is transferred from the heat generation body to the flow pipe to heat water flowing in the flow pipe. At this time, the heat conductor is made of a material having high thermal conductivity such as aluminum, and is 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 is 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.

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.

6, the beverage extracting unit 160 is provided with a capsule mounting portion (not shown) on which a beverage capsule 165 such as a coffee capsule is mounted, and a high pressure water (or steam) So that the liquid coffee is extracted. 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 pressurized water from the pump 153 can be introduced into the coffee capsule 165 do. 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.

6, 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 cover 167 and a lower cover 168 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.

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

A lower part of the beverage extracting unit 160 is 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, Respectively.

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. 1, but they may be formed by combining them.

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 controls 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 judged that a block phenomenon has occurred in the inside.

Accordingly, when the flow rate detected by the second flow rate sensor 152 is less than the preset flow rate, the controller 170 controls the driving of the pump 153 to cope with the blocking phenomenon.

Specifically, when the flow rate sensed by the second flow rate sensor 152 is less than the preset 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.

7 and 8, during a period of time t _2a to t _2b of at least a part of the re-application of the voltage (t _2a to t _2c ) of the pump 153, A second voltage V ₂ higher than the first voltage V ₁ applied to the pump 153 can be applied to the pump 153 during the initial operation of the pump 153.

7 and 8, when a voltage applied to the pump 153 at the time of initial driving (t ₀ to t ₁ ) of the pump 153 is referred to as a first voltage V ₁ , ₁ to t _2a ). The second voltage (V ₂ ) for restoration after the stop of the pump (153) can be made larger than the first voltage (V ₁ ). Thus, the case for increasing the second voltage (V ₂₎ than the first voltage (V ₁₎ higher pressure than in the case of applying a first voltage (V ₁₎ to the pump 153 is applied to the coffee capsule 165 So that it is easier to solve the block phenomenon of the coffee powder 169.

Further, the control unit 170 to rebuild at the same time, pump 153, the second set voltage (V ₂₎ the time (t _2a ~ t _2b) after applying said second voltage (V ₂₎ during the pump 153 A lower third voltage V ₃ can be applied for the remaining time t _2b to t _2c . That is, since the blocking phenomenon can be solved by applying the second voltage V ₂ , which is larger than the first voltage V ₁ , to the pump 153, it is not necessary to keep the second voltage V ₂ , t _2a to t _2b ), the third voltage (V ₃ ) lower than the second voltage (V ₂ ) can be supplied.

The third voltage V ₃ may be set to be equal to the first voltage V ₁ as shown in FIG. 7, and may be set to be greater than the first voltage V ₁ It may be set high.

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 blocking 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.

When the flow rate sensed by the second flow rate sensor 152 is less than the set flow rate at the time of the re-start of the pump 153, the controller 170 stops the pump 153 for the set time, It can be restarted. That is, as shown in FIGS. 7 and 8, the pump 153 can be driven again after a predetermined time (t _2c to t _3a ) has elapsed. Also in this case, the second voltage V ₂ is applied to the pump 153 for the set time t ₃ to t _3b and is lower than the second voltage V ₂ for the remaining time t _3b to t _3c The third voltage V ₃ can be applied.

If the flow rate sensed by the second flow sensor 152 continues to be smaller than the preset flow rate after the pump 153 is restarted, the pump 153 may be restarted and then restarted. However, (For example, three times), if the set flow rate can not be reached even when the pump 153 is restarted, the waiting time of the user becomes excessively long. In addition, by the above-described method, the blockage of the coffee powder 169 It may be difficult to resolve.

Accordingly, when the number of re-driving of the pump 153 is equal to or greater than the set number of times, the control unit 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.

Meanwhile, the controller 170 can inform the user of the cleaning time of the beverage extracting unit 160 through the display unit 180.

For example, when a predetermined time elapses based on the last time the beverage extracting unit 160 is used, the controller 170 displays a wash notification through the display unit 180, (Not shown).

In this case, the indication of the cleaning indication of the display unit 180 does not disappear, and when the user has cleaned the beverage extraction unit 160 Only the wash 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 beverage can be supplied to the user more quickly.

When the cover (not shown) provided in the beverage extracting unit 160 is opened and is not closed even after a predetermined time has elapsed, the control unit 170 controls the heater 154 to stop preheating .

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 operation unit 185, the extraction 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.

9, the flow path between the heater 154 and the beverage extraction unit 160 is branched by the fifth branch R5 to the beverage supply passage L11 and the bypass passage L12 And a bypass valve 155 may be provided in the bypass line L12.

There may be a residue in the flow path between the heater 154 and the beverage extracting unit 160 during the beverage extraction process and there is a fear that the temperature of the water supplied to the beverage extracting unit 160 may be lowered due to such residual water have.

That is, even if water at a high temperature (for example, 90 to 95 ° C) is supplied to the heater 154, the temperature of water entering the beverage extracting unit 160 can be lowered by the residual water.

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

The bypass valve 155 is connected to the drain port 156 of the beverage extracting unit 160 through the bypass line L12.

Therefore, the remaining amount 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, if 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 is 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 preset temperature.

The heater 154 is heated until the temperature of the heater 154 reaches a predetermined temperature (for example, 90 to 95 DEG C) sufficient for extracting the beverage. When the temperature of the heater 154 reaches a predetermined temperature, .

While the pump 153 is being driven, the bypass valve 155 remains open for a predetermined 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 is discharged to the outside.

When the predetermined time (for example, two seconds) has elapsed while the bypass valve 155 is opened while the pump 153 is being driven, the bypass valve 155 is closed and the pump 153 The high-temperature, high-pressure water is supplied to the beverage extracting unit 160 to extract the beverage.

When the beverage is extracted, the driving of the pump 153 is stopped, and the driving of the beverage supply unit 150 is 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 is preheated.

The heater 154 is heated until the temperature of the heater 154 reaches a predetermined temperature (for example, 90 to 95 DEG C) sufficient for extracting the beverage. When the temperature of the heater 154 reaches a predetermined temperature, .

By driving the pump 153, high-temperature, high-pressure water is supplied to the beverage extracting unit 160 to extract the beverage.

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

Even if the driving of the pump 153 is stopped, a residual pressure exists in the internal flow path of the beverage supply unit 150, The number can be discharged to the outside.

When the bypass valve 155 is opened for a predetermined period of time (for example, two seconds), the bypass valve 155 is closed, and the driving of the beverage supply unit 150 is 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 the driving of the pump 153, and then the beverage is extracted. And the driving of the pump 153 is stopped, the bypass valve 155 is opened and closed for a predetermined time (for example, two seconds).

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

In this way, the bypass valve 155 is opened during the beverage extraction process to discharge the residual water present in the flow path between the heater 154 and the beverage extraction unit 160, so that the water supplied from the heater 154 It is possible to prevent the temperature from varying.

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.

4, when the user selects the beverage extraction and the ice extraction through the operation unit 185, the beverage is stored in the ice storage unit (not shown) while the beverage is extracted through the beverage extraction unit 150 The ice can be provided to the user.

That is, since beverage extraction and ice extraction can be performed at the same time, a user who wants a cold beverage can mix a hot beverage and ice to drink a cold beverage.

5, in an ice water purifier 100 having a beverage extracting function according to an embodiment of the present invention, a beverage such as coffee and a cold water and / or purified water can be simultaneously extracted at the user's choice have. Of course, as described with reference to Fig. 4, extraction of ice can also be performed at the same time.

Thus, it is possible for a user to drink cold water and / or purified water without any waiting time during the extraction of beverages such as coffee.

However, when extracting beverages such as coffee or the like, the extraction of hot water is limited.

Since the heater 154 for supplying the beverage and the instantaneous heating unit 130 for supplying the hot water simultaneously operate when the beverage and the hot water such as coffee are extracted at the same time, there is a risk of malfunction due to overload or breakage of the apparatus, It is preferable that the extraction of the beverage and the extraction of the hot water are not performed at the same time.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be obvious to those of ordinary skill in the art.
