In this case, one material accommodating part may be an initial material accommodating part, and the other material accommodating part may be a final material accommodating part. An outlet of the first material accommodating unit and an inlet of the final material accommodating unit may be connected by a connection channel.

As another example, when there are a plurality of intermediate material accommodating units, four or more material accommodating units may be formed in the material supplier 3 . In this case, one material accommodating part may be an initial material accommodating part, another material accommodating part may be a final material accommodating part, and the remaining material accommodating part may be an intermediate material accommodating part. In this case, since the serial connection relationship between each material accommodating portion can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

Since the plurality of material accommodating portions 31, 32, and 33 are connected in series, the channel configuration of the material feeder 3 can be simplified. In addition, since the additives contained in each of the capsules (C1, C2, and C3) are extracted at once, there is an advantage in that the required time is shortened.

The controller 281A first introduces water into the fermentation container 12 and then stops it, then injects air into the fermentation container 12 and then stops it, and finally into the fermentation container 12. It is possible to stop after the second inflow of hot water, and it is also possible to complete the water supply step (S200) after completing all of the first water inflow, the air injection, and the second water inflow sequentially.

An example of the water supplying step (S200) may be carried out only the hot water supplying process of supplying hot water.

Another example of the water supply step (S200) is to sequentially perform a first hot water supply process for firstly supplying hot water, an air injection process for injecting air, and a second hot water supply process for injecting hot water secondly. .

As an example of the water supplying step (S200), when only the hot water supplying process is performed in the water supplying step (S200), the details are the same as those described above, and thus a detailed description thereof will be omitted.

Hereinafter, as another example of the water supply step (S200), a case in which the first hot water supply process, the air injection process, and the second hot water supply process are sequentially performed in the water supply step (S200) will be described.

The controller 281A may turn on the feed water pump 52 and the feed water heater 53 and open the bypass valve 35 and the main valve 40 at the start of the first hot water supply process. The supply valve 310 can be kept closed. In addition, the controller 281A may open the gas discharge valve 73 and the exhaust valve 156 at the start of the first hot water supply process.

During the first hot water supply process, water may be introduced into the fermentation container 12, the fermentation container 12 may be inflated by the inflowing water, and there is a gap between the fermentation container 12 and the fermentation tank 112. Some of the air may be pushed by the expanding fermentation container 12 and flow into the air supply channel 154, and may be exhausted to the outside through the exhaust valve 156.

Also, the controller 281A may determine the completion of the first hot water supply process according to the flow rate sensed by the flow meter 56 during the first hot water supply process. When the flow rate detected by the flow meter 56 reaches the first set flow rate during the first hot water supply process, the controller 281A determines that the first hot water supply process is complete, and the water pump 52 and the water heater ( 53) can be turned off, and the open state of the bypass valve 35 and the main valve 40 can be maintained. In addition, the controller 281A may maintain the open state of the gas discharge valve 73 and the exhaust valve 156 upon completion of the first hot water supply process.

When the first hot water supplying process is completed, an air injection process may be performed.

The controller 281A may turn on the air pump 82 at the start of the air injection process. Also, the controller 281A may keep the air supply valve 159 closed.

While the air pump 82 is on, air injected into the air injection channel 81 can flow from the first main channel 41 to the second main channel 42 through the bypass channel 43, It may pass through valve 40 and flow into fermentation container 12 . In this way, the air introduced into the fermentation container 12 may hit the liquid malt to help the malt and hot water be more evenly mixed.

As air flows into the fermentation container 12, the fermentation container 12 can be inflated, and some of the air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 is expanded fermentation container 12 It can be pushed to the air supply channel 154 and can be exhausted to the outside through the exhaust valve 156.

The controller 281A may complete the air injection process when the pressure detected by the gas pressure sensor 72 is equal to or greater than the set pressure, and may turn off the air pump 82 to complete the air injection process. When the air injection process is completed, the control module 280 may keep the main valve 40, the bypass valve 35, the gas discharge valve 73, and the exhaust valve 156 open.

When the air injection process is completed, a second hot water supplying process may be performed.

The controller 281A may turn on the feed water pump 52 and the feed water heater 53 when the secondary hot water supply process starts.

Water in the water tank 51 may be supplied to the fermentation container 12 as in the first hot water supply process, and new hot water may be additionally supplied to the fermentation container 12.

When the secondary hot water is supplied as described above, the fermentation container 12 can be further expanded by the additionally introduced water, and some of the air remaining between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 Pushed by the inflated fermentation container 12, it may flow into the air supply channel 154, and may be exhausted to the outside through the exhaust valve 156.

The controller 281A may determine the completion of the secondary hot water supply process according to the flow rate detected by the flow meter 56 during the secondary hot water supply process. When the flow rate detected by the flow meter 56 reaches the second set flow rate during the secondary hot water supply process, the controller 281A determines that the secondary hot water supply process is complete, and the water pump 52 and the water heater ( 53) can be turned off, and the main valve 40 and the bypass valve 35 can be closed. Also, upon completion of the secondary hot water supply process, the controller 281A may close the gas discharge valve 73 and the exhaust valve 156.

Meanwhile, the beverage manufacturing step may include a fermentation tank cooling step (S300).

In more detail, when the water supply step (S200) is completed, a fermentation tank cooling step (S300) of cooling the fermentation tank 112 may be performed.

The controller 281A may control the temperature controller 11 for cooling of the fermenter 112. In more detail, the controller 281A may control the refrigeration cycle device 13 for cooling the fermenter 112. The refrigerant may take heat from the fermentation tank 112 while passing through the evaporator 134 and evaporate. When the refrigerating cycle device 13 is driven, the fermentation tank 112 may be gradually cooled, and the fermentation container 12 accommodated in the fermentation tank 112 and the liquid malt contained in the fermentation container 12 may be cooled.

When the fermentation tank 112 is cooled as described above, the evaporator 134 may cool the fermentation container 12, and the controller 281A freezes according to the temperature detected by the temperature sensor 16 installed in the fermentation tank 112. The cycle device 13 can be controlled.

The controller 281A may control the compressor so that the temperature sensed by the temperature sensor 16 is maintained at a set temperature (eg, 35° C.). In more detail, the controller 281A may turn on the compressor of the refrigeration cycle device 13 when the temperature detected by the temperature sensor 16 exceeds the compressor on temperature (eg, 35.5° C.). The control module 280 may turn off the compressor when the temperature detected by the temperature sensor 16 is equal to or less than the compressor off temperature (eg, 34.5° C.).

Since the feed water heater 53 is turned off during the additive input step (S500) to be described later, the temperature of the fermentation container 12 is set during the cooling step (S300) by the water introduced into the fermentation container 12 together with the additives. It may be slightly lower than the set temperature. For example, the temperature of the fermentation container 12 is maintained at about 35 ° C. until then, and when the additive and the water are put into the fermentation container 12 together, the temperature of the fermentation container 12 may decrease to about 30 ° C. Therefore, it is preferable that the set temperature in the cooling step (S300) is determined in consideration of this temperature drop.

The controller 281A may keep the exhaust valve 156 closed during the fermentation tank cooling step (S300), and the air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 passes through the exhaust valve 156 to the outside. It does not escape, and the air inside the fermenter 112 can be quickly cooled.

Exceptionally, when the temperature of the fermentation container 12 is lower than the set temperature even when the refrigerating cycle device 13 is turned off because the external temperature is very low, the controller 281A controls the heater 14 located at the bottom of the fermentation tank 112. ) can be turned on. The controller 281A may turn on the heater 14 when the temperature detected by the temperature sensor 16 is lower than the heater on temperature. The control module 280 may turn off the heater when the temperature detected by the temperature sensor 16 is equal to or higher than the heater off temperature.

On the other hand, the beverage manufacturing step may include an air supply step (S400).

In more detail, in the beverage maker, after the fermentation tank cooling step (S300) is initiated and the compressor of the refrigeration cycle device 13 is turned on, the temperature detected by the temperature sensor 16 is at least once below the compressor off temperature, An air supply step (S400) of mixing liquid malt by supplying air into the fermentation container 12 may be performed. Alternatively, in the beverage maker, when the fermentation tank cooling step (S300) is initiated and the heater 14 is turned on, the temperature detected by the temperature sensor 16 is at least once the heater off temperature or higher, the fermentation container 12 An air supply step (S400) of mixing liquid malt by supplying air therein may be performed.

The beverage maker can turn on and off the refrigerating cycle device 13 and the heater 14 according to the temperature detected by the temperature sensor 16 even during the air supply step (S400), and such a refrigerating cycle device 13 And the on/off control of the heater 14 may be continued until the additive input step (S500) to be described later is completed.

During the air supply step (S400), the controller 281A may turn on the air pump 82 and open the bypass valve 35 and the main valve 40. In addition, the controller 281A may open the gas discharge valve 73 and the exhaust valve 156, and may keep the air supply valve 159 and the material supply valve 310 closed.

While the air pump 82 is on, air injected into the air injection channel 81 can flow from the first main channel 41 to the second main channel 42 through the bypass channel 43, It may pass through valve 40 and flow into fermentation container 12 . As such, the air introduced into the fermentation container 12 may help the malt and hot water to be more evenly mixed by hitting the liquid malt, and the air hitting the liquid malt may supply oxygen to the liquid malt. That is, agitation and aeration can be performed.

While air is injected into the fermentation container 12, the fermentation container 12 may be inflated by the air injected into the fermentation container 12. Some of the air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 may be pushed by the expanding fermentation container 12 and flow into the air supply channel 154, and may flow to the outside through the exhaust valve 156. can be exhausted. As a result, the fermentation container 12 can be easily inflated, and air in the second main channel 42 can quickly flow into the fermentation container 12 and be mixed with liquid malt.

The controller 281A can mix air into liquid malt for the mixing set time when the air pump 82 is turned on, and the air supply step (S400) can be completed when the air pump 82 is turned on and the mixing set time elapses. there is. Upon completion of the air supply step (S400), the controller 281A may turn off the air pump 82 and close the bypass valve 35. In addition, the controller 281A may close the gas discharge valve 73 and the exhaust valve 156 upon completion of the air supply step (S400).

The beverage preparation step may include an additive input step (S500).

In more detail, the beverage maker may perform an additive input step (S500) after the air supply step (S400).

In the additive input step (S500), the first additive of the first capsule (C1), the second additive of the second capsule (C2), and the third additive of the third capsule (C3) are introduced into the fermentation container (12). It can be. At this time, the first capsule (C1) is a capsule mounted on the first capsule mounting portion 31, the second capsule (C2) is a capsule mounted on the intermediate capsule mounting portion 32, and the third capsule (C3) is a final capsule. It is a capsule mounted on the mounting portion 33.

During the additive input step (S500), the controller 281A may turn on the feed water pump 52 and maintain the feed water heater 53 in an off state. Also, the controller 281A may keep the bypass valve 35 closed and open the material supply valve 310 and the main valve 40 . Also, the controller 281A may open the gas discharge valve 73 and the exhaust valve 156.

When the feed water pump 52 is turned on, the water in the water tank 51 flows through the feed water pump 52 and the feed water heater 53 to the first main channel 41, passes through the material supply valve 310, It can flow into the first capsule (C1). Water introduced into the first capsule C1 may be mixed with the first additive contained in the first capsule C1 and flow together with the first additive into the first connection channel 311 .

The fluid (a mixture of water and the first additive) introduced into the second capsule C2 through the first connection channel 311 is mixed with the second additive contained in the second capsule C2, and the second additive It can flow to the second connection channel 312 together with.

The fluid (a mixture of water, the first additive and the second additive) introduced into the third capsule C3 through the second connection channel 312 is mixed with the third additive contained in the third capsule C3, , It can flow into the second main channel 42 together with the third additive.

The fluid (a mixture of water, the first additive, the second additive, and the third additive) flowing through the second main channel 42 may pass through the main valve 40 and be introduced into the fermentation container 12 . Thus, all of the additives contained in each of the capsules C1, C2, and C3 may be put into the fermentation container 12.

The controller 281A may complete the additive input process S500 when the cumulative flow rate detected by the flow meter 56 reaches the additive input set flow rate from the start of the additive input process S500. Upon completion of the additive input process (S500), the controller 281A may turn off the water supply pump 52.

The beverage preparation step may include a material feeder residual water removal step (S600).

In more detail, when all of the additive inputting step (S500) is completed, a material feeder residual water removing step (S600) of removing residual water in the material feeder 3 may be performed.

In the step of removing residual water from the material supplier (S600), the controller 281A may turn on the air pump 82 and keep the air supply valve 159 closed. In addition, the controller 281A may open and control the material supply valve 310 and the main valve 40 . Also, the controller 281A may open and control the gas discharge valve 73 and the exhaust valve 156 .

When the air pump 82 is turned on, the air injected into the air injection channel 81 flows into the first main channel 41 and passes through the material supply valve 310 to flow into the first capsule C1. . The air introduced into the first capsule (C1) passes through the first capsule (C1), the second capsule (C2), and the third capsule (C3) in order, and the residual water remaining in each is transferred to the second main channel (42). can blow The air flowing through the second main channel 42 may flow into the fermentation container 12 together with the residual water.

As a result, additives and residual water remaining in each of the capsules C1, C2, and C3 without being extracted can be introduced into the fermentation container 12 without leaving any residue.

As residual water and air are injected into the fermentation container 12 from the second main channel 42, the fermentation container 12 can be further expanded, and there is a gap between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112. Some of the air may be pushed by the expanding fermentation container 12 and flow into the air supply channel 154, and may be exhausted to the outside through the exhaust valve 156. Thus, the fermentation container 12 can be easily inflated, and air and residual water in the second main channel 42 can be quickly introduced into the fermentation container 12 .

The controller 281A may turn on the air pump 82 for a set residual water removal time, and may complete the step of removing residual water from the material supplier (S600) when the set residual water removal time elapses.

When the material supply residual water removal step (S600) is completed, the controller 281A may turn off the air pump 82, and may close the material supply valve 310 and the main valve 40. Also, the controller 281A may close the gas discharge valve 73 and the exhaust valve 156.

The controller 281A may display a capsule separation message indicating that the capsules C1, C2, and C3 may be removed on the display 282 when the step of removing residual water from the material supplier (S600) is completed, and the user may use the material supplier ( In 3), the empty capsule can be removed.

The beverage preparation step may include fermentation steps (S700) and (S800).

In more detail, after the completion of the material feeder residual water removal step (S600), the first fermentation step (S700) and the second fermentation step (S800) may be sequentially performed.

According to an example of the first fermentation step (S700), the first fermentation step (S700) may include the entire fermentation process and the main fermentation process. This fermentation process may be carried out after the entire fermentation process is completed.

The entire fermentation process is a process for rapidly and actively activating the yeast added to the fermentation container 12 during the additive input step (S500).

The controller 281A may control the refrigerating cycle device 13 and the heater 14 so that the temperature measured by the temperature sensor 16 maintains the target temperature of the entire fermentation (eg, 30 ° C) during the entire fermentation process. there is. The controller 281A periodically opens and closes the gas discharge valve 73 after the entire fermentation process starts, and stores the pressure value detected by the gas pressure sensor 72 immediately after the gas discharge valve 73 is closed. It can be stored in a sub (not shown). The controller 281A may compare the stored pressure value with a pressure value sensed after a predetermined time elapses in a closed state of the gas discharge valve 73 to calculate a change in pressure. The controller 281A may determine that all fermentation is completed when the calculated pressure change exceeds the pre-fermentation set pressure, and complete the entire fermentation process.

The controller 281A may start the fermentation process when the entire fermentation process is completed.

The controller 281A may control the refrigeration cycle device 13 and the heater 14 so that the temperature measured by the temperature sensor 16 maintains the fermentation target temperature (eg, 21 ° C) during the fermentation process. there is. At this time, the fermentation target temperature may be lower than the total fermentation target temperature.

After starting the fermentation process, the control module 280 periodically opens and closes the gas discharge valve 73, and stores the pressure detected by the gas pressure sensor 72 while the gas discharge valve 73 is closed. not shown). When the change in pressure periodically detected by the gas pressure sensor 72 exceeds the main fermentation set pressure, the control module 280 may determine that the main fermentation is complete and complete the primary fermentation step (S700).

However, the first fermentation step (S700) is not limited thereto, and according to another example of the first fermentation step (S700), the first fermentation step (S700) may include only this fermentation process without including the entire fermentation process. there is. Descriptions thereof are omitted because they are redundant.

Meanwhile, the controller 281A may start the second fermentation step (S800) after the first fermentation step (S700) is completed.

The controller 281A may control the refrigerating cycle device 13 and the heater 14 so that the temperature measured by the temperature sensor 16 becomes the secondary fermentation target temperature during the secondary fermentation step (S800).

Since the internal pressure of the fermentation container 12 is high during the secondary fermentation step (S800), when the gas discharge valve 73 is opened, there is a risk of generating loud noise. In order to solve the above concerns, the controller 281A keeps the gas discharge valve 73 closed during the second fermentation step (S800) and opens/closes the pressure release valve 76 equipped with the noise reduction device 77. You can control it.

After the second fermentation step (S800) starts, the controller 281A periodically opens and closes the pressure release valve 76, and the pressure detected by the gas pressure sensor 72 while the pressure release valve 76 is closed. may be stored in a storage unit (not shown). When the change in pressure periodically detected by the gas pressure sensor 72 exceeds the second fermentation set pressure, the controller 281A determines that the secondary fermentation is complete, and may complete the secondary fermentation step (S800).

The beverage manufacturing step may include a ripening step (S900).

In more detail, when both the first fermentation step (S700) and the second fermentation step (S800) are completed, the aging step (S900) may be performed.

During the aging step, the controller 281A may stand by for the aging time, and during this aging time, the temperature of the beverage is maintained between the upper limit of the set aging temperature and the lower limit of the set aging temperature. 14) can be controlled.

Since the beverage maker is mainly used indoors, the temperature outside the beverage maker is generally between the upper limit of the set aging temperature and the lower limit of the set aging temperature, or higher than the upper limit of the set aging temperature. In this case, the controller 281A may turn off the compressor of the refrigerating cycle device 13 when the temperature detected by the temperature sensor 16 is less than the lower limit of the set ripening temperature, and the temperature detected by the temperature sensor 16 is If it is more than the upper limit of the set aging temperature, the compressor can be turned on.

Exceptionally, when the temperature outside the beverage maker is lower than the lower limit of the set aging temperature, the controller 281A may turn on the heater 14 when the temperature detected by the temperature sensor 16 is less than the lower limit, and the temperature sensor 16 ) If the detected temperature is higher than the upper limit of the set ripening temperature, the heater 14 may be turned off.

When the aging time has elapsed in the beverage maker, all beverage preparations may be completed.

However, in some cases, the aging step (S900) may be omitted and the preparation of the beverage may be completed when the secondary fermentation step (S800) is completed.

The controller 281A may display the completion of preparation of the beverage through the display 282 or the like.

In addition, the controller 281A may control the compressor 134 to maintain the temperature of the fermenter 112 between an upper limit and a lower limit of a preset drinking temperature. The controller 281A may turn on the compressor of the refrigerating cycle device 13 when the temperature detected by the temperature sensor 16 is higher than the upper limit of the drinking temperature, and the temperature detected by the temperature sensor 16 is higher than the lower limit of the drinking temperature. When low, the compressor can be turned off. As a result, the beverage maker can always provide a cool beverage to the user.

The controller 281A may maintain the temperature of the fermenter 112 between the upper and lower limits of the predetermined drinking temperature until the beverage dispensing step (S1000) to be described later is completed.

The beverage maker according to an embodiment of the present invention may further include a beverage dispensing step (S1000) of dispensing the beverage after beverage preparation is completed.

According to an example of the beverage dispensing step (S1000), the beverage dispensing step (S1000) may include a beverage dispensing process and a dispenser cleaning process.

In the beverage dispensing step (S1000), the user may manipulate the dispenser 62 to dispense the beverage.

When the user opens the dispenser 62 after beverage preparation is completed, the controller 281A may open the main valve 40 and the beverage dispensing valve 64 .

When the main valve 40 and the beverage take-out valve 64 are opened, the beverage in the fermentation container 12 is released from the fermentation container 12 by air pressure between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112. It can flow into the second main channel 42, flow from the second main channel 42 to the beverage dispensing channel 61, and can be dispensed into the dispenser 62.

When the user closes the dispenser 62 after partially dispensing a beverage through the dispenser 62, the controller 281A may close the main valve 40 and the beverage dispensing valve 64. As a result, one beverage dispensing process can be completed.

Thereafter, the controller 281A may turn on the air pump 82, open the air supply valve 159, and keep the exhaust valve 156 closed.

When the air pump 82 is turned on, the air injected into the air injection channel 81 flows from the first main channel 41 to the air supply channel 154, and the outer surface of the fermentation container 12 and the fermentation tank 112 It can be supplied between the inner walls of. The air between the outer surface of the fermentation container 12 and the inner wall of the fermentation vessel 112 may pressurize the fermentation container 12 to a pressure that allows the beverage in the fermentation container 12 to rise into the second main channel 42. . This is to form a sufficiently high pressure between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 so that the beverage in the fermentation container 12 can be smoothly and quickly taken out during subsequent beverage dispensing.

A user may take out a beverage at least once through the dispenser 62 . That is, the beverage dispensing process may be performed at least once, and the controller 281A determines the time when the dispenser 62 is open, the time when the air pump 152 is driven, and the main valve 40 after beverage preparation is completed. It is possible to determine whether or not beverage dispensing has been completed using information such as the on-in time.

The controller 281A may close the air supply valve 159 when beverage dispensing is completed. In addition, the controller 281A may open the exhaust valve 156 for a set completion time when beverage dispensing is complete and the dispenser 62 is in a closed state.

When the exhaust valve 156 is controlled to open, the air between the outer surface of the fermentation container 12 and the inner wall of the fermenter 112 is exhausted to the exhaust valve 156 through the air supply channel 154 and the exhaust channel 157. The pressure in the space between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 may be equal to atmospheric pressure.

The controller 281A may close the exhaust valve 156 when the completion set time has elapsed after turning on the exhaust valve 156 .

If the cleaning step (S1100) is not performed after beverage dispensing is completed, or if the cleaning step (S1100) does not include a main channel cleaning process to be described later, the controller 281A displays the fermentation container 12 on the display 282 or the like. may prompt you to uninstall the pack. A user may open fermentation lid 107 to take fermentation container 12 out of fermenter module 111 .

When the fermentation lid 107 is opened as described above, if the inside of the fermentation tank 112 is at a pressure higher than the set pressure than the atmospheric pressure, the fermentation container 12 may bounce upward of the fermentation tank 112 due to this pressure difference.

On the other hand, before the user opens the fermentation lid 107, if some of the air between the fermentation container 12 and the fermentation tank 112 is exhausted through the exhaust valve 156, when the fermentation lid 107 is opened , The fermentation container 12 is maintained inside the fermentation tank 112 without bouncing upward.

That is, the user can safely and cleanly withdraw the used fermentation container 12 from the fermentation tank 112.

Meanwhile, the dispenser cleaning process may be performed after at least one beverage dispensing process.

When a considerable time interval exists between the completion of the last beverage dispensing process and the next beverage dispensing process, the inside of the dispenser channel 611 may be contaminated by the beverage remaining in the dispenser channel 611 (see FIG. 4). There are possible concerns.

Accordingly, when the user intends to dispense a beverage after the dispenser cleaning set time elapses from the last beverage dispensing process, the controller 281A may perform the dispenser cleaning process.

In more detail, the controller 281A may start a timer (not shown) when each beverage dispensing process is completed, and reset the timer when the next beverage dispensing process is started. The controller 281A may perform a dispenser cleaning process when the timer elapses the dispenser cleaning set time and the dispenser 62 is opened.

In addition, the controller 281A may perform a dispenser cleaning process by receiving a dispenser cleaning command from an input unit or a mobile terminal.

When the dispenser cleaning process starts, the controller 281A may display a cleaning notification on the display 282 or the like. The cleaning notification may include content instructing the user not to bring a cup or glass to the dispenser 62 .

An example of the dispenser cleaning process may include a water cleaning process and an air cleaning process.

During the water washing process, the controller 281A may turn on the water supply pump 52. In addition, the controller 281A may open the sub valve 92 and the beverage dispensing valve 64 and keep the material supply valve 310 and the bypass valve 35 closed.

When the water supply pump 52 is turned on, the water sucked into the water supply pump 52 in the water tank 51 can flow from the water supply channel 55B to the sub-channel 91, and passes through the sub-valve 92 to drink beverages. It can flow into the dispensing channel 61, pass through the beverage dispensing valve 64, and be dispensed into the dispenser 62. In the process of dispensing the water into the dispenser 62 , it may be dispensed together with debris and foreign substances inside the dispenser channel 611 to perform cleaning.

Water and foreign substances taken out by the dispenser 62 may fall into the beverage container 101 (see FIG. 2).

The controller 281A may complete the water washing process when the water washing process starts and the accumulated water quantity of the flow meter 56 reaches the water washing set flow rate. At this time, the water washing set flow rate may be less than the cleaning set flow rate during the cleaning steps (S100) (S1100).

When the water washing process is completed, the controller 281A may turn off the water supply pump. Also, the controller 281A may start an air washing process when the water washing process is completed.

The controller 281A may turn on the air pump 82 when the air washing process starts.

When the air pump 82 is turned on, the air injected from the air pump 82 through the air injection channel 81 into the first main channel 41 passes through the water heater 53 and into the sub channel 91. It flows, passes through the sub valve 92, flows into the beverage dispensing channel 61, passes through the beverage dispensing valve 64, and can be discharged to the dispenser 62. In the process of discharging the air to the dispenser 62, the air may be taken out along with residual water remaining in the dispenser channel 611 to perform cleaning. Accordingly, it is possible to minimize the influence of remaining water on the taste of the beverage in the subsequent beverage dispensing process.

The controller 281A may complete the air washing process when the air washing process starts and the air washing set time elapses. When the air cleaning process is completed, the controller 281A may turn off the air pump 82 and close the sub valve 92 . In this way, the dispenser cleaning process may be completed.

When the dispenser cleaning process is completed, the controller 281A may start the beverage dispensing process again.

On the other hand, when all beverages in the fermentation container 12 are taken out and the controller 281A determines that the beverage is taken out, the controller 281A may further perform a beverage preparation step and a cleaning step after the beverage takeout (S1100).

The cleaning step (S1100) after preparing the beverage and dispensing the beverage may include at least one of a first cleaning process and a second cleaning process. When the cleaning step ( S1100 ) includes a first cleaning process and a second cleaning process, the order of performing each cleaning process may not be limited.

Since the first cleaning process is the same as or similar to the cleaning step (S100) before the beverage manufacturing step described above, overlapping information will be omitted. Hereinafter, the second cleaning process will be described.

The second cleaning process is carried out in a state in which beverage dispensing is completed and the empty fermentation container 12 is mounted, or the user removes the empty fermentation container 12 and attaches a separate cleaning pack to the fermentation tank 112. may be performed later. Hereinafter, for convenience of explanation, a case in which a separate cleaning pack is accommodated in the fermentation tank 112 will be described as an example.

When the beverage extraction from the fermentation container 12 is completed, the controller 281A may display a container replacement notification on the display 282 or the like. A user may open the fermentation lid, remove the empty fermentation container 12 from the fermentation vessel 112, and insert a separate cleaning pack into the fermentation vessel 112. Thereafter, the fermentation lid 107 may be closed.

After that, the controller 281A may start a second cleaning process.

When the second cleaning process starts, the controller 281A may turn on the water supply pump 52 and the water supply heater 53 and close the beverage dispensing valve 64 . In addition, the controller 281A may open the material supply valve 310, the bypass valve 35 and the main valve 40.

When the second cleaning process starts, the controller 281A may open the gas discharge valve 73 and the exhaust valve 156 . Also, the controller 281A may open the sub valve 92.

When the feed water pump 52 is turned on, water in the water tank 51 flows to the feed water heater 53 and can be heated in the feed water heater 53 .

Water heated by the feedwater heater 53 (ie, hot water) may be divided into a sub channel 91 and a first main channel 41 to flow.

Water flowing through the sub-channel 91 may flow into the beverage dispensing channel 61 through the sub-valve 92 . Water flowing through the beverage dispensing channel 61 may flow into the second main channel 42 , pass through the main valve 40 , and flow into the cleaning pack accommodated in the fermenter 112 .

In addition, the water flowing through the first main channel 41 may be divided into the material supplier 3 and the bypass channel 43 to flow.

The water flowing through the material feeder 3 sequentially passes through the material supply valve 310, the first capsule mounting part 31, the intermediate capsule mounting part 32, and the final capsule mounting part 33 to the second main channel 43. It can flow and pass through the main valve 40 and flow into the cleaning pack accommodated in the fermenter 112.

The water flowing into the bypass channel 43 passes through the bypass valve 35 and flows into the second main channel 43, and passes through the main valve 40 to the cleaning pack accommodated in the fermentation tank 112. can be infiltrated.

During the above control, the main channels 41 and 42, the bypass channel 43, the sub-channel 91, the valves installed in each of the channels, and the main channel connection part 115 can be sterilized and washed. In addition, each capsule mounting portion 31, 32, 33 and the connection channel 311, 312 can be sterilized and washed.

The controller 281A may perform the cleaning as described above during the second cleaning set time, and may complete the second cleaning process after the second cleaning set time.

The controller 281A may turn off the water supply pump 52 and the water supply heater 53 after the second cleaning set time has elapsed, the main valve 40, the bypass valve 35, and the material supply valve 310 ), the sub valve 92, the gas discharge valve 73, and the exhaust valve 156 can be closed.

Meanwhile, after the cleaning step (S1100) is completed, the user may open the fermentation reed 107 and take out the cleaning pack containing the water that has been washed in the fermentation tank 112 for treatment.

Figure 6 is a flowchart for explaining the temperature control steps of the beverage maker according to an embodiment of the present invention.

During some of the beverage preparation steps performed by the beverage maker as shown in FIG. 5 and storage of the prepared beverage, the beverage maker may perform a temperature control operation for controlling the temperature of the fermenter 112.

Referring to FIG. 6 in relation to the temperature control operation, the beverage maker may perform the fermentation tank cooling control step (S2000).

The step S2000 may be performed in the fermentation tank cooling step (S300) of FIG. 5. The controller 281A may control the temperature controller 11 to cool the fermentation tank 112 in the fermentation tank cooling step. Specifically, the controller 281A may drive the refrigeration cycle device 13 to cool the fermentation tank 112 and lower the temperature of the fermentation tank 112 based on the set temperature of the fermentation steps S700 and S800. there is.

The step S2000 of controlling the cooling of the fermentation tank 112 may be continuously performed until the fermentation tank cooling step (S300) to the material feeder residual water removal step (S600) are completed.

In the fermentation steps (S700) (S800) of the beverage maker, the beverage maker may perform the fermentation temperature control step (S2100).

The controller 281A may control the temperature controller 11 to adjust the temperature of the fermenter 112 based on the fermentation set temperature. Specifically, the controller 281A may control at least one of the refrigerating cycle device 13 and the heater 14 to maintain the temperature of the fermenter 112 in a range between the upper and lower limits of the set fermentation temperature.

Depending on the embodiment, as described above in FIG. 5 , when the primary fermentation step (S700) includes pre-fermentation and main fermentation, the pre-fermentation set temperature and the main fermentation set temperature may be different from each other. For example, the pre-fermentation set temperature may be set higher (about 28 °C to 35 °C) than the main fermentation set temperature (eg, about 21 °C) to promote yeast activation.

In this case, the controller 281A controls at least one of the refrigeration cycle device 13 and the heater 14 to maintain the temperature of the fermenter 112 in the range between the upper limit and the lower limit of the pre-fermentation set temperature during the pre-fermentation step. can do. In addition, the controller 281A controls at least one of the refrigerating cycle device 13 and the heater 14 to maintain the temperature of the fermenter 112 in the range between the upper limit and the lower limit of the main fermentation set temperature during the main fermentation step. can

In the aging step (S900) after completion of the fermentation step (S700) (S800) of the beverage maker, the beverage maker may perform the aging temperature control step (S2200).

The aging setting temperature in the aging step may be lower than the fermentation setting temperature. Accordingly, the controller 281A may control the refrigeration cycle device 13 to lower the temperature of the fermenter 112 at the beginning of the ripening temperature control step (S2200). When the temperature of the fermenter 112 reaches the aging set temperature (or the lower limit of the aging set temperature) by driving the refrigerating cycle device 13, the controller 281A may stop the driving of the refrigerating cycle device 13. . Thereafter, the controller 281A may control at least one of the refrigerating cycle device 13 and the heater 14 so that the temperature of the fermenter 112 is maintained within a range between the upper and lower limits of the maturation temperature.

After the aging of the beverage is complete, the beverage maker may perform a storage temperature control step (S2300) for the prepared beverage.

The storage temperature of the beverage may be lower than the aging set temperature. Accordingly, the controller 281A may control the refrigeration cycle device 13 to lower the temperature of the fermenter 112 at the beginning of the storage temperature control step (S2300). When the temperature of the fermenter 112 reaches the storage temperature (or the lower limit of the storage temperature) by driving the refrigerating cycle device 13, the controller 281A may stop driving the refrigerating cycle device 13. Thereafter, the controller 281A may control at least one of the refrigerating cycle device 13 and the heater 14 so that the temperature of the fermenter 112 is maintained within a range between the upper limit value and the lower limit value of the storage temperature.

7 is an exemplary diagram showing a fermentor temperature change according to a general temperature control operation of a beverage maker according to an embodiment of the present invention.

Referring to FIG. 7, as described above in FIG. 6, the controller 281A of the beverage maker operates at least one of the refrigeration cycle device 13 and the heater 14 to adjust the temperature of the fermenter 112 according to each temperature control step. You can control one.

For example, the controller 281A may stop driving the refrigerating cycle device 13 when the temperature of the fermenter 112 reaches the lower limit of the set temperature for each temperature control step.

As shown in FIG. 7, the controller 281A controls the refrigerating cycle device 13 at the first time point T1 when the temperature of the fermenter reaches the lower limit value ST1-M of the fermentation set temperature in the fermentation tank cooling control step S2000. ) can be stopped.

However, despite the fact that the driving of the refrigerating cycle device 13 is stopped at the first time point T1, the temperature of the fermenter may further decrease to a predetermined temperature TEMP. In particular, the driving time of the refrigerating cycle device 13 in the fermentation tank cooling control step (S2000) is the driving time (T3-T2) of the refrigerating cycle device 13 at the beginning of the aging temperature control step (S2200), and the storage temperature control step (S2300) may be longer than the driving time (T5-T4) of the refrigerating cycle device 13 at the beginning.

That is, as the driving time of the refrigerating cycle device 13 increases, the amount of remaining cooling heat after stopping the driving of the refrigerating cycle device 13 increases, so that the fermenter temperature remains even after stopping the driving of the refrigerating cycle device 13 at the first time point T1. You can descend further. On the other hand, in the aging temperature control step (S2200) and the storage temperature control step (S2300), in which the driving time of the refrigerating cycle device 13 is relatively short, the refrigerating cycle device at the third time point T3 and the fifth time point T5 After the driving of (13) is stopped, there may be no or minimal drop in fermenter temperature.

In this case, the controller 281A may increase the temperature of the fermenter by driving the heater 14, but when the capacity of the heater 14 provided in the beverage maker is small, the rate of increase of the temperature of the fermentor may be slow. When the fermenter temperature is lower than the lower limit of the fermentation set temperature, a problem arises in that yeast in the form of powder introduced for the fermentation step is not smoothly activated. As the yeast is not smoothly activated, the growth and reproduction of the yeast may not be performed effectively, so that the fermentation step may not be normally performed. As a result, the quality of the prepared beverage, such as taste or aroma, may deteriorate, resulting in lower user satisfaction.

To solve this problem, the beverage maker may adjust the temperature of the fermenter according to different criteria according to the temperature control step shown in FIG. 6 . An embodiment related to this will be described with reference to FIGS. 8 to 9 below.

8 is a flow chart specifically showing a temperature control operation of a beverage maker according to an embodiment of the present invention, and FIG. 9 is an exemplary view showing a fermentor temperature change according to a temperature control operation of the beverage maker shown in FIG. 8 .

Referring to FIG. 8, the beverage maker may check whether the current temperature control step is the fermentation tank cooling control step (S2000) (S3000). As a result of the confirmation, if the current temperature control step is the fermentation tank cooling control step (YES in S3000), the beverage maker may drive the refrigerating cycle device 13 (S3010).

In the case of the fermentation tank cooling control step (S2000), since hot water is introduced into the fermentation tank 112 and the fermentation tank temperature is higher than the fermentation set temperature, the controller 281A can drive the refrigeration cycle device 13 to lower the fermentation tank temperature. there is.

The beverage maker may stop driving the refrigeration cycle device 13 when the fermentation tank temperature is lower than the set temperature (set fermentation temperature) (YES in S3020) (S3030).

The controller 281A may detect the temperature of the fermenter using the temperature sensor 16.

For example, when the fermentation set temperature is 21°C and the margin value is 0.5°C, the lower limit of the fermentation set temperature may be 20.5°C and the upper limit of the fermentation set temperature may be 21.5°C.

The controller 281A may stop the driving of the refrigerating cycle device 13 before the fermentation tank temperature reaches the lower limit of the fermentation set temperature, that is, when the fermentation tank temperature is higher than the lower limit of the fermentation set temperature. Preferably, the operation of the refrigerating cycle device 13 may be stopped at a specific time when the fermenter temperature is higher than the lower limit value of the set fermentation temperature and lower than the upper limit value. In step S3020, it is shown that the operation of the refrigerating cycle device 13 is stopped when the fermentation tank temperature is lower than the fermentation set temperature, but this corresponds to an embodiment for convenience of explanation. That is, according to the embodiment, the controller 281A may stop driving the refrigerating cycle device 13 when the temperature of the fermenter becomes lower than the upper limit of the set fermentation temperature.

On the other hand, if the current temperature control step is the other control steps (S2100) (S2200) (S2300) except for the fermentation tank cooling control step (S2000) (NO in S3000), the beverage maker sets the temperature of the fermentor to the set temperature in each control step. It is possible to drive the refrigerating cycle device 13 or the heater 14 so as to adjust the range between the upper limit value and the lower limit value.

Specifically, in the beverage maker, if the fermentation tank temperature is higher than the sum of the set temperature (fermentation set temperature, aging set temperature, or storage set temperature) and the margin value of the current temperature control step, that is, the upper limit of the set temperature (YES in S3040), The temperature of the fermenter may be lowered by driving the refrigeration cycle device 13 (S3050).

Thereafter, the beverage maker stops driving the refrigerating cycle device 13 when the fermentation tank temperature reaches the difference between the set temperature and the margin value, that is, the lower limit value of the set temperature (or lower than the lower limit value) (YES in S3060) It can be done (S3070).

That is, the controller 281A may stop driving the refrigerating cycle device 13 when the temperature of the fermenter reaches the lower limit of the set temperature in step S3060, unlike step S3020. As described above in FIG. 7, in the case of the aging temperature control step (S2200) or the storage temperature control step (S2300), the driving time of the refrigerating cycle device 13 is relatively short compared to the fermentation tank cooling control step (S2000), so the remaining This is because the additional drop in temperature of the fermenter due to the freezing heat is also relatively small.

That is, in the case of the fermentation tank cooling control step (S2000), the beverage maker controls the operation of the refrigerating cycle device 13 to be stopped under conditions different from the other steps (S2100) (S2200) (S2300), thereby further lowering the temperature of the fermenter. Thus, it is possible to prevent a phenomenon in which yeast is not smoothly activated.

In this regard, referring to FIG. 9, unlike the embodiment shown in FIG. 7, the controller 281A is refrigerated at the time T1 when the temperature of the fermentor reaches the fermentation set temperature ST1 in the fermentation tank cooling control step S2000. By stopping the driving of the cycle device 13, it is possible to prevent the fermenter temperature from being lower than the lower limit value (ST1-M) of the set fermentation temperature. That is, in the fermentation temperature control step (S2100), the controller 281A can precisely control the fermenter temperature between the lower limit value (ST1-M) and the upper limit value (ST1+M) of the set fermentation temperature.

8, the beverage maker uses the heater 14 to raise the temperature of the fermenter when the fermenter temperature is lower than the difference between the set temperature and the margin value of the current temperature control step, that is, the lower limit of the set temperature (YES in S3080) can be driven (S3090).

Thereafter, the beverage maker can stop driving the heater 14 when the fermentation tank temperature reaches the sum of the set temperature and the margin value, that is, the upper limit value of the set temperature (or higher than the upper limit value) (YES in S3100) (S3110).

That is, the beverage maker can prevent the quality of the beverage from deteriorating due to temperature fluctuations by precisely adjusting the temperature of the fermenter within the range between the lower limit and the upper limit of the set temperature.

10 is a flowchart specifically showing a temperature control operation of a beverage maker according to another embodiment of the present invention.

In the case of a beverage maker according to an embodiment of the present invention, the temperature sensor 16 may be disposed at a position spaced apart from each of the refrigerating cycle device 13 and the heater 14.

On the other hand, when the external temperature is low and the temperature of the beverage being manufactured or stored in the fermentation tank 112 is low, the density of the beverage may be increased. In this case, the flow of the beverage is reduced, and there is a possibility that the temperature of the beverage in the fermenter 112 is not uniform.

For example, during operation of the refrigerating cycle device 13, the rate of decrease of the temperature of the fermenter around the refrigeration cycle device 13 (or beverage temperature) may be faster than the rate of decrease of the temperature of the fermenter around the temperature sensor 16. Accordingly, even if the temperature of the fermenter around the refrigerating cycle device 13 reaches the lower limit of the set temperature, the temperature of the fermentor around the temperature sensor 16 may be detected higher than the lower limit of the set temperature. As a result, the refrigerating cycle device 13 is continuously driven so that the beverage present around the refrigerating cycle device 13 is supercooled, and the quality of the beverage may deteriorate.

In this regard, referring to FIG. 10, in the beverage maker, when the fermentation tank temperature detected by the temperature sensor 16 is higher than the sum of the set temperature and the first margin value of the current temperature control step, that is, the upper limit of the set temperature (S4000 YES of), it is possible to drive the refrigerating cycle device 13 to lower the temperature of the fermenter (S4010).

On the other hand, the beverage maker may count the driving time of the refrigerating cycle device 13 and compare the driving time with the reference time. The reference time may correspond to a preset time when the product is shipped to prevent overcooling by the refrigerating cycle device 13 .

When the driving time exceeds the reference time (YES in S4020), the beverage maker when the fermentation tank temperature reaches the difference between the set temperature and the second margin value (or when lower than the difference between the set temperature and the second margin value) (YES in S4030), it is possible to stop driving the refrigerating cycle device 13 (S4050).

On the other hand, if the driving time does not exceed the reference time (NO in S4020), the beverage maker when the fermentation tank temperature reaches the difference between the set temperature and the first margin value, that is, the lower limit of the set temperature (or the set temperature and the first If lower than the margin value difference) (YES in S4040), it is possible to stop driving the refrigerating cycle device 13 (S4050).

The second margin value in step S4030 may be smaller than the first margin value, and in this case, the difference between the set temperature and the second margin value may be higher than the lower limit value of the set temperature. Therefore, in step S4030, the controller 281A may stop driving the refrigerating cycle device 13 when the fermenter temperature reaches a temperature value higher than the lower limit of the set temperature.

That is, the beverage maker according to the embodiment of the present invention, based on the comparison result of the driving time of the refrigerating cycle device 13 and the reference time, it is possible to adjust the temperature value for stopping the driving of the refrigerating cycle device 13 . Specifically, in the beverage maker, when the driving time of the refrigerating cycle device 13 exceeds the reference time, the fermenter temperature detected by the temperature sensor 16 is the lower limit of the set temperature in order to prevent overcooling due to a decrease in the flow of the beverage. Even if it does not reach, the driving of the refrigerating cycle device 13 can be stopped.

The above description is merely an example of the technical idea of the present invention, and various modifications and variations can be made to those skilled in the art without departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention, but to explain, and the scope of the technical idea of the present invention is not limited by these embodiments.

The protection scope of the present invention should be construed according to the claims below, and all technical ideas within the equivalent range should be construed as being included in the scope of the present invention.
