In this case, any one material receiving portion may be the original material receiving portion, the other material receiving portion may be the final material receiving portion, and the remaining material receiving portion may be the intermediate material receiving portion. In this case, since the serial connection relation between the respective material accommodating portions can be easily understood by those skilled in the art, detailed description is omitted.

The plurality of material receiving portions 31, 32, and 33 are connected in series, which has an advantage that the channel configuration of the material feeder 3 can be simplified. Further, since the additive contained in each of the capsules (C1), (C2) and (C3) is extracted at one time, there is an advantage that the required time is shortened. In addition, since the user does not have to worry about the mounting order of the capsules C1, C2, and C3, malfunctions caused by mounting the capsules C1, C2, and C3 in the wrong order may not occur. In addition, the leakage point of the material feeder 3 is minimized, so that reliability can be always maintained.

As an example of the watering step (S200), the case where the watering step (S200) is performed only in the hot water supplying process is the same as that described above, and therefore, a detailed description thereof will be omitted.

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

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

Water may be introduced into the fermentation container 12 during the primary hot water supply process and the fermentation container 12 may be expanded by the incoming water and the water may be introduced between the fermentation container 12 and the fermentation tank 112 Some of the air may be pushed into the expanding fermentation container 12 to flow into the air supply channel 154 and be exhausted to the outside through the exhaust valve 156.

The controller 281A can determine 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. The controller 281A determines that the first hot water supply process is completed when the flow rate sensed by the flow meter 56 reaches the first set flow rate during the first hot water supply process and controls the water supply 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 can maintain the open state of the gas discharge valve 73 and the exhaust valve 156 at the completion of the primary hot water supply process.

When the first hot water supply process is completed, the air injection process can be performed.

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

The 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 while the air pump 82 is on, And may be introduced into the fermentation container 12 through the valve 40. In this way, the air introduced into the fermentation container 12 can hit the liquid malt so that the malt and hot water can be mixed more evenly.

As the air is introduced into the fermentation container 12, the fermentation container 12 can be inflated and a portion of the air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 is introduced into the fermentation container 12, To the air supply channel 154, and can be exhausted to the outside through the exhaust valve 156.

The controller 281A can complete the air injection process and turn off the air pump 82 to complete the air injection process if the pressure sensed by the gas pressure sensor 72 is equal to or higher than the set pressure. The control module 280 can 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.

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

The controller 281A can turn on the water feed pump 52 and the water heater 53 at the start of the second hot water supply process.

Water in the water tank 51 can be supplied to the fermentation container 12 as in the case of the first hot water supply process and fresh water can be additionally supplied to the fermentation container 12.

During the second hot water supply, the fermentation container 12 can be further inflated by the incoming 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 Can be pushed by the expanding fermentation container 12 to flow into the air supply channel 154 and can be exhausted to the outside through the exhaust valve 156.

The controller 281A can determine completion of the second hot water supply process according to the flow rate sensed by the flow meter 56 during the second hot water supply process. The controller 281A determines that the second hot water supply process is completed when the flow rate sensed by the flow meter 56 reaches the second set flow rate in the middle of the second hot water supply process and the water supply pump 52 and the water heater 53) and close the main valve (40) and the bypass valve (35). Further, at the completion of the second hot water supply process, the controller 281A can close the gas discharge valve 73 and the exhaust valve 156. [

On the other hand, the beverage preparation step may include a fermentation tank cooling step (S300).

More specifically, when the watering step (S200) is completed, a fermentation tank cooling step (S300) for cooling the fermentation tank (112) may be performed.

The controller 281A can control the temperature controller 11 to cool the fermenter 112. [ More specifically, the controller 281A may control the refrigeration cycle unit 13 to cool the fermentation tank 112. [ The refrigerant passes through the evaporator 134, takes heat of the fermentation tank 112, and can be evaporated. The fermentation tank 112 can be gradually cooled and the fermentation container 12 accommodated in the fermentation tank 112 and the liquid malt contained in the fermentation container 12 can be cooled.

The evaporator 134 can cool the fermentation container 12 and the controller 281A can cool the fermentation container 12 according to the temperature sensed by the temperature sensor 16 provided in the fermentation tank 112, It is possible to control the cycle device 13.

The controller 281A can control the compressor such that the temperature sensed by the temperature sensor 16 is maintained at a set temperature (e.g., 35 DEG C). More specifically, the controller 281A can turn on the compressor of the refrigeration cycle device 13 if the temperature sensed by the temperature sensor 16 is above the compressor on temperature (e.g., 35.5 ° C). The control module 280 may turn off the compressor if the temperature sensed by the temperature sensor 16 is below the compressor off temperature (e.g., 34.5 [deg.] C).

The water heater 53 is turned off in the additive injecting step S500 to be described later and the water introduced into the fermentation container 12 together with the additive is set to the temperature at which the temperature of the fermentation container 12 was set at the cooling step S300 It can be lowered somewhat compared to the set temperature. For example, if the temperature of the fermentation container 12 is maintained at about 35 ° C., the temperature of the fermentation container 12 may be lowered to about 30 ° C. when the additive and water are introduced into the fermentation container 12. Therefore, it is preferable that the set temperature in the cooling step (S300) is determined in consideration of such a temperature lowering.

The controller 281A can 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 is exhausted through the exhaust valve 156 to the outside And the air inside the fermentation tank 112 can be quickly cooled.

If the temperature of the fermentation container 12 is lower than the set temperature even when the temperature of the outside is extremely low and the refrigeration cycle device 13 is turned off, the controller 281A controls the heater 14 Can be turned on. The controller 281A can turn on the heater 14 if the temperature sensed by the temperature sensor 16 is lower than the heater on temperature. The control module 280 may turn off the heater if the temperature detected by the temperature sensor 16 is equal to or higher than the heater off temperature.

Meanwhile, the beverage manufacturing step may include an air supply step (S400).

More specifically, if the temperature sensed by the temperature sensor 16 is at least once below the compressor off temperature after the fermenter cooling step S300 as described above is started and the compressor of the refrigeration cycle device 13 is turned on, (S400) in which air is supplied into the fermentation container 12 to mix the liquid malt. Alternatively, the beverage maker may operate in the fermentation container 12 if the temperature sensed by the temperature sensor 16 is at least once above the heater-off temperature when the fermentation tank cooling step S300 is started and the heater 14 is turned on, (S400) for mixing the liquid malt with the air can be performed.

The beverage maker can turn on and off the refrigeration cycle unit 13 and the heater 14 according to the temperature sensed by the temperature sensor 16 even during the air supply step S400, And the heater 14 can be continued until the additive injecting step (S500) described later is completed.

The controller 281A turns on the air pump 82 and opens the bypass valve 35 and the main valve 40 at the air supply step S400. Further, the controller 281A can open the gas discharge valve 73 and the exhaust valve 156, and can keep the air supply valve 159 and the material supply valve 310 closed.

The 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 while the air pump 82 is on, And may be introduced into the fermentation container 12 through the valve 40. Thus, the air introduced into the fermentation container 12 can help the malt and hot water to be mixed more evenly by bumping the liquid malt, and the air impinging on the liquid malt can supply oxygen to the liquid malt. That is, stirring and aeration can be performed.

While air is being injected into the fermentation container 12, the fermentation container 12 may be inflated by air injected into the fermentation container 12. A portion of the air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 can be pushed by the fermentation container 12 to be expanded and flowed into the air supply channel 154, Can be exhausted. Thereby, the fermentation container 12 can be easily expanded, and the air in the second main channel 42 can be quickly introduced into the fermentation container 12 and mixed with the liquid malt.

The controller 281A can complete the air supply step S400 when the air pump 82 is turned on and the mixing set time has elapsed so that the air pump 82 can be turned on and mix the air into the liquid malt during the mixing set time have. Upon completion of the air supply step (S400), the controller (281A) can turn off the air pump (82) and close the bypass valve (35). Further, the controller 281A may close the gas discharge valve 73 and the exhaust valve 156 at the completion of the air supply step (S400).

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

More specifically, the drink maker may perform the additive adding step (S500) after the supply step (S400).

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 at the additive injecting step S500 . The second capsule C2 is a capsule mounted on the intermediate capsule mounting portion 32 and the third capsule C3 is a capsule mounted on the final capsule 30, And is mounted on the mounting portion 33.

At the additive injecting step S500, the controller 281A can turn on the water feed pump 52 and keep the water heater 53 in the off state. The controller 281A can keep the bypass valve 35 closed and open the material supply valve 310 and the main valve 40. [ Further, the controller 281A can open the gas discharge valve 73 and the exhaust valve 156. [

The water in the water tank 51 flows into the first main channel 41 through the water feed pump 52 and the water heater 53 and flows through the material supply valve 310 And may be introduced into the first capsule C1. Water introduced into the first capsule C1 can be mixed with the first additive contained in the first capsule C1 and flow into the first connection channel 311 together with the first additive.

The fluid (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, To the second connection channel (312).

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

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

The controller 281A can complete the additive injecting process (S500) when the cumulative flow rate detected by the flow meter 56 reaches the additive load setting flow rate from the start of the additive injecting process (S500). Upon completion of the additive injecting process (S500), the controller 281A can turn off the water feed pump (52).

The beverage manufacturing step may include a step S600 of removing the material supplier residuals.

More specifically, when the additive adding step (S500) is completed, a material feeder residual amount removing step (S600) for removing the residual water in the material feeder (3) may be performed.

In step S600, the controller 281A turns on the air pump 82 and keeps the air supply valve 159 closed. Further, the controller 281A can open control the material supply valve 310 and the main valve 40. [ In addition, the controller 281A can open control the gas discharge valve 73 and the exhaust valve 156. [

The air injected into the air injection channel 81 flows into the first main channel 41 and flows into the first capsule C1 through the material supply valve 310 when the air pump 82 is turned on . The air introduced into the first capsule C1 flows through the first capsule C1, the second capsule C2 and the third capsule C3 in order and the residual water remaining in each of them passes through the second main channel 42 You can blow it. The air that has flowed into the second main channel 42 may flow into the fermentation container 12 together with residual water.

As a result, the additives and residues remaining in the capsules (C1), (C2) and (C3), which have not been extracted yet, can be fed into the fermentation container (12).

As the 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 the fermentation container 12 can be expanded, Some of the air may be pushed into the expanding fermentation container 12 to flow into the air supply channel 154 and be exhausted to the outside through the exhaust valve 156. Thereby, the fermentation container 12 can be easily inflated, and the air and the residual water of the second main channel 42 can be rapidly introduced into the fermentation container 12.

The controller 281A can turn on the air pump 82 for the set remaining time of the remaining amount of water and complete the step S600 of removing the remaining amount of the material supplying unit when the set remaining time of the remaining amount of time has elapsed.

 The controller 281A can turn off the air pump 82 and close the material supply valve 310 and the main valve 40 when the step S600 of removing the material feeder residuals is completed. Further, the controller 281A can close the gas discharge valve 73 and the exhaust valve 156. [

The controller 281A may display a capsule separation message indicating that capsules C1, C2 and C3 may be removed from the display 282 upon completion of the material supplier residual amount removal step S600, 3) to remove empty capsules.

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

More specifically, after the completion of the step S600 of removing the material feeder residual amount, the primary fermentation step (S700) and the secondary fermentation step (S800) may be sequentially performed.

According to one example of the first fermentation step (S700), the first fermentation step (S700) may include a pre-fermentation process and a main fermentation process. This process of fermentation may be carried out after the completion of the pre-fermentation process.

The pre-fermentation process is a process for rapidly and actively activating the yeast added to the fermentation container 12 in the additive adding step S500.

The controller 281A can control the refrigeration cycle device 13 and the heater 14 so that the temperature measured by the temperature sensor 16 maintains the pre-fermentation target temperature (for example, 30 占 폚) have. The controller 281A periodically opens and closes the gas discharge valve 73 after the start of the pre-fermentation process and stores the pressure value sensed by the gas pressure sensor 72 immediately after the gas discharge valve 73 is closed (Not shown). The controller 281A can calculate the change amount of the pressure by comparing the stored pressure value with the pressure value sensed after a predetermined time elapses from the state in which the gas discharge valve 73 is closed. If the calculated amount of change in the pressure exceeds the pre-fermentation setting pressure, the controller 281A can determine that the pre-fermentation has been completed and complete the pre-fermentation process.

The controller 281A can start the main fermentation process when the pre-fermentation process is completed.

The controller 281A can control the refrigeration cycle device 13 and the heater 14 so that the temperature measured at the temperature sensor 16 maintains the main fermentation target temperature (for example, 21 DEG C) have. At this time, the present fermentation target temperature may be lower than the pre-fermentation target temperature.

The control module 280 periodically opens and closes the gas discharge valve 73 after the start of the main fermentation process and the pressure sensed by the gas pressure sensor 72 during the closing of the gas discharge valve 73, Not shown). The control module 280 may determine that the main fermentation is completed when the change in the pressure periodically sensed by the gas pressure sensor 72 exceeds the main fermentation set pressure and complete the first fermentation step S700.

However, the first fermentation step (S700) is not limited thereto. According to another example of the first fermentation step (S700), the first fermentation step (S700) may include only the present fermentation process have. The explanation of this is redundant and will be omitted.

On the other hand, the controller 281A can start the secondary fermentation step (S800) after the completion of the primary fermentation step (S700).

The controller 281A can control the refrigeration 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 stage (S800).

In the second fermentation step (S800), since the internal pressure of the fermentation container (12) is high, opening of the gas discharge valve (73) may cause a large noise. The controller 281A keeps the gas discharge valve 73 closed during the secondary fermentation step S800 and sets the pressure release valve 76 provided with the noise reduction device 77 to open / close Can be controlled.

The controller 281A periodically opens and closes the pressure release valve 76 after the start of the secondary fermentation step S800 and the pressure sensed by the gas pressure sensor 72 while the pressure release valve 76 is closed May be stored in a storage unit (not shown). The controller 281A may determine that the secondary fermentation is completed when the change in the pressure periodically sensed by the gas pressure sensor 72 exceeds the second fermentation set pressure and complete the secondary fermentation step S800.

The beverage preparation step may include an aging step (S900).

More specifically, when the primary fermentation step (S700) and the secondary fermentation step (S800) are all completed, the aging step (S900) may be performed.

The controller 281A can wait for the aging time during the aging step and the temperature of the beverage is kept between the upper limit value of the set aging temperature and the lower limit value of the set aging temperature during the aging time, 14 can be controlled.

Since the beverage maker is mainly used indoors, the temperature outside the beverage maker is generally between the upper limit value of the set maturity temperature and the lower limit value of the set maturity temperature, or higher than the upper limit value of the set maturity temperature. In this case, the controller 281A can turn off the compressor of the refrigeration cycle apparatus 13 when the temperature sensed by the temperature sensor 16 is lower than the lower limit value of the set maturing temperature, and the temperature sensed by the temperature sensor 16 If the upper limit of the set maturation temperature is exceeded, the compressor can be turned on.

The controller 281A can turn on the heater 14 if the temperature sensed by the temperature sensor 16 is lower than the lower limit value and the temperature sensor 16 ), The heater 14 can be turned off if the detected temperature is higher than the upper limit of the set maturing temperature.

When the beverage maker has elapsed the aging time, all beverage manufacturing can be completed.

However, in some cases, the aging step S900 may be omitted and the beverage may be completed when the second fermentation step S800 is completed.

The controller 281A can indicate the completion of the manufacture of the beverage through the display 282 or the like.

The controller 281A can also control the compressor 134 to maintain the temperature of the fermentation tank 112 between the upper limit value and the lower limit value of the predetermined drinking temperature. The controller 281A can turn on the compressor of the refrigeration cycle apparatus 13 when the temperature sensed by the temperature sensor 16 is equal to or higher than the upper limit value of the drinking temperature and the temperature sensed by the temperature sensor 16 is lower than the lower limit value of the drinking temperature The compressor can be turned off. Whereby the drink maker can always provide the user with a cool drink.

The controller 281A can maintain the temperature of the fermentation tank 112 between the upper limit value and the lower limit value of the predetermined drinking temperature until the beverage taking-out step (S1000) to be described later is completed.

The beverage maker according to an embodiment of the present invention may further include a beverage taking-out step (S1000) for taking out the beverage after the beverage manufacturing is completed.

According to one example of the beverage taking-out step S1000, the beverage taking-out step S1000 may include a beverage taking-out process and a dispenser cleaning process.

In the beverage taking-out step (S1000), the user can operate the dispenser 62 to take out the beverage.

After the beverage manufacturing is completed, when the user opens the dispenser 62, the controller 281A can open the main valve 40 and the beverage extraction valve 64. [

When the main valve 40 and the beverage extraction valve 64 are opened, the beverage in the fermentation container 12 is introduced into the fermentation container 12 by the air pressure between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 Can be flowed to the second main channel 42 and flowed from the second main channel 42 to the beverage extraction channel 61 and can be taken out to the dispenser 62.

The controller 281A can close the main valve 40 and the beverage extraction valve 64 when the user closes the dispenser 62 after partially taking out the beverage through the dispenser 62. [ Thereby, the one-time drink extracting process can be completed.

Thereafter, the controller 281A can 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 flows to the outer surface of the fermentation container 12 and the fermentation tank 112, As shown in FIG. The air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 can press the fermentation container 12 at a pressure such that the beverage in the fermentation container 12 can be raised to the second main channel 42 . The inner wall of the fermentation tank 112 and the outer surface of the fermentation container 12 are formed at a sufficiently high pressure so that the beverage in the fermentation container 12 can be taken out smoothly and promptly at the time of taking out the beverage afterwards.

The user can take out the drink at least once through the dispenser 62. [ That is, the beverage taking-out process can be performed at least once, and the controller 281A can control the time at which the dispenser 62 is opened, the time at which the air pump 152 is driven, It is possible to determine whether or not the beverage extraction is completed using the information such as the time when the beverage is turned on.

The controller 281A can close the air supply valve 159 when the beverage extraction is completed. In addition, the controller 281A can open the exhaust valve 156 for the completion setting time when the beverage removal is completed and the dispenser 62 is closed.

During the open control of the exhaust valve 156, air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 is exhausted to the exhaust valve 156 through the air supply channel 154 and the exhaust channel 157 And the pressure in the space between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 can be equal to the atmospheric pressure.

The controller 281A can turn on the exhaust valve 156 and then close the exhaust valve 156 when the completion set time has elapsed.

If the cleaning step S1100 is not performed after the beverage removal is completed or the cleaning step S1100 does not include the main channel cleaning process to be described later, the controller 281A controls the fermentation container 12, such as the display 282, To remove the unpacked message. The user may open the fermentation lid 107 to remove the fermentation container 12 from the fermentation module 111. [

When the inside of the fermentation tank 112 is at a higher pressure than the atmospheric pressure or higher when the fermentation lid 107 is opened, the fermentation container 12 can bounce to the upper portion of the fermentation tank 112 due to such a pressure difference.

On the other hand, when a part of the air between the fermentation container 12 and the fermentation tank 112 is exhausted through the exhaust valve 156 before the user opens the fermentation lid 107, when the fermentation lid 107 is opened , The fermentation container 12 does not bounce upward but is retained inside the fermentation tank 112.

That is, the user can take the fermented container 12, which has been used safely and cleanly, from the fermentation tank 112.

On the other hand, the dispenser cleaning process may be performed after at least one beverage taking-out process.

If there is a considerable time interval between the completion of the last beverage taking process and the next beverage taking process, the inside of the dispenser channel 611 is contaminated by the beverage remaining in the dispenser channel 611 (see FIG. 4) There is a concern.

Accordingly, when the user intends to take out the beverage after the dispenser cleaning set time has elapsed from the last beverage taking out process, the controller 281A can perform the dispenser cleaning process.

More specifically, the controller 281A can start a timer (not shown) when each drink taking process is completed, and can reset the timer when the next drink taking process starts. The controller 281A may perform a dispenser cleaning process when the timer expires and the dispenser 62 is opened.

Also, the controller 281A may receive a dispenser cleaning command from an input unit, a mobile terminal, or the like, and perform a dispenser cleaning process.

When the dispenser cleaning process is started, the controller 281A can display a cleaning notification on the display 282 and the like. The cleaning notification may include notifying the user that the dispenser 62 does not draw a cup or a cup.

One example of a dispenser cleaning process may include a water washing process and an air cleaning process.

In the water washing process, the controller 281A can turn on the water supply pump 52. [ The controller 281A can open the sub valve 92 and the beverage extraction 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, Can be flowed to the outlet channel 61 and can be taken out to the dispenser 62 through the beverage extraction valve 64. [ In the process of taking out the water to the dispenser 62, the water can be taken out together with the scum and the foreign matter in the dispenser channel 611 to perform cleaning.

The water and the foreign matter taken out by the dispenser 62 can fall into the beverage container 101 (see Fig. 2).

The controller 281A can complete the water washing process when the cumulative quantity of the flow meter 56 reaches the water washing set flow rate from the start of the water washing process. At this time, the water washing set flow rate may be smaller than the cleaning set flow rate in the cleaning step S100 (S1100).

The controller 281A can turn off the water supply pump when the water washing process is completed. Further, the controller 281A can start the air cleaning process when the water cleaning process is completed.

The controller 281A can turn on the air pump 82 when the air cleaning process is started.

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

The controller 281A can complete the air cleaning process when the air cleaning process is started and the air cleaning setting time has elapsed. When the air cleaning process is completed, the controller 281A can turn off the air pump 82 and close the sub valve 92. [ Thereby, the dispenser cleaning process can be completed.

The controller 281A can start the drink taking-out process again when the dispenser cleaning process is completed.

On the other hand, if the controller 281A determines that the beverage is completely taken out of the fermentation container 12 and the controller 281A has completed the beverage extraction, the controller 281A can further perform the beverage manufacturing step and the cleaning step S1100 after the beverage extraction.

The cleaning step S1100 after the beverage preparing step and the beverage removing step may include at least one of the first cleaning step and the second cleaning step. When the cleaning step S1100 includes the first cleaning process and the second cleaning process, the order of execution of each cleaning process may not be limited.

The first cleaning process is the same as or similar to the cleaning process (S100) before the beverage manufacturing process described above, so duplicate description is omitted. The second cleaning process will be described below.

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

The controller 281A can display a container replacement notification on the display 282 or the like when the beverage extraction of the fermentation container 12 is completed. The user may open the fermentation lead, remove the fermentation container 12 from the fermentation tank 112, and insert a separate cleaning pack into the fermentation tank 112. Thereafter, the fermentation reed 107 can be closed.

Then, the controller 281A can start the second cleaning process.

At the start of the second cleaning process, the controller 281A can turn on the water feed pump 52 and the water heater 53, and can close the beverage extraction valve 64. [ Further, the controller 281A can open the material supply valve 310, the bypass valve 35 and the main valve 40. [

At the start of the second cleaning process, the controller 281A can open the gas discharge valve 73 and the exhaust valve 156. [ Further, the controller 281A can open the sub valve 92. Fig.

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

The water heated by the water heater 53 (i.e., hot water) can be divided into the sub-channel 91 and the first main channel 41 and flow.

The water that has flowed into the sub-channel (91) can flow through the sub-valve (92) to the beverage extraction channel (61). The water that has flowed into the beverage extraction channel 61 flows into the second main channel 42 and flows into the cleaning pack stored in the fermentation tank 112 through the main valve 40.

In addition, the water flowing into the first main channel 41 can be divided into the material feeder 3 and the bypass channel 43 and flow.

The water that has flowed into the material feeder 3 sequentially passes through the material supply valve 310, the initial capsule mounting portion 31, the intermediate capsule mounting portion 32 and the final capsule mounting portion 33 to the second main channel 43 And may be introduced into the cleaning pack contained in the fermentation tank 112 through the main valve 40.

FIG. 6 is a flowchart illustrating temperature control steps of a 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 during storage of the prepared beverage, the beverage maker may perform a temperature control operation to control the temperature of the fermenter 112.

Referring to FIG. 6 in connection with the temperature control operation, the beverage maker may perform the fermenter cooling control step (S2000).

The step S2000 may be performed in the fermenter cooling step S300 of FIG. The controller 281A can control the temperature controller 11 to cool the fermenter 112 in the fermenter cooling stage. Specifically, the controller 281A drives the refrigeration cycle unit 13 to cool the fermentation tank 112 and can lower the temperature of the fermentation tank 112 based on the set temperature of the fermentation steps S700 and S800 have.

The step S2000 for controlling the cooling of the fermentation tank 112 may be continuously performed until the fermentation tank cooling step S300 to the material feeder stock removal step S600 is completed.

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

The controller 281A can control the temperature controller 11 to adjust the temperature of the fermenter 112 based on the fermentation set temperature. Specifically, the controller 281A can control at least one of the refrigeration cycle apparatus 13 and the heater 14 so as to maintain the temperature of the fermentation tank 112 within a range between the upper limit value and the lower limit value of the fermentation set temperature.

According to the embodiment, when the primary fermentation step (S700) includes the pre-fermentation and the main fermentation as described above with reference to FIG. 5, 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 than the main fermentation set temperature (e.g., about 21 캜) (about 28 캜 to 35 캜) to promote activation of yeast.

In this case, the controller 281A controls at least one of the refrigeration cycle device 13 and the heater 14 so as to maintain the temperature of the fermentation tank 112 within a range between the upper limit value and the lower limit value of the pre- can do. The controller 281A controls at least one of the refrigeration cycle apparatus 13 and the heater 14 so as to maintain the temperature of the fermentation tank 112 within a range between the upper limit value and the lower limit value of the main fermentation set temperature at the main fermentation stage .

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

The aging set temperature of the aging step may be lower than the fermentation set temperature. Accordingly, the controller 281A can control the refrigeration cycle apparatus 13 to lower the temperature of the fermentation tank 112 at the beginning of the maturing temperature control step S2200. When the temperature of the fermentation tank 112 reaches the aging set temperature (or the lower limit value of the aging set temperature) by driving the refrigeration cycle unit 13, the controller 281A can stop the driving of the refrigeration cycle unit 13 . Thereafter, the controller 281A can control at least one of the refrigeration cycle apparatus 13 and the heater 14 so that the temperature of the fermentation tank 112 is maintained in the range between the upper limit value and the lower limit value of the aging temperature.

After the fermentation of the beverage is completed, the beverage maker may perform the 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 can control the refrigeration cycle apparatus 13 to lower the temperature of the fermentation tank 112 at the beginning of the storage temperature control step S2300. When the temperature of the fermentation tank 112 reaches the storage temperature (or the lower limit value of the storage temperature) by driving the refrigeration cycle unit 13, the controller 281A can stop driving the refrigeration cycle unit 13. [ The controller 281A can control at least one of the refrigeration cycle apparatus 13 and the heater 14 so that the temperature of the fermentation tank 112 is maintained in the range between the upper limit value and the lower limit value of the storage temperature.

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

6, the controller 281A of the beverage maker controls at least one of the refrigeration cycle device 13 and the heater 14 to adjust the temperature of the fermentation tank 112 according to each temperature control step, You can control one.

For example, the controller 281A can stop driving the refrigeration cycle device 13 when the temperature of the fermentation tank 112 reaches the lower limit value of the set temperature for each temperature control step.

7, at a first time point T1 at which the fermentation tank temperature reaches the lower limit value ST1-M of the fermentation set temperature in the fermentation tank cooling control step S2000, the controller 281A controls the refrigeration cycle apparatus 13 Can be stopped.

However, although the driving of the refrigeration cycle device 13 is stopped at the first time point T1, the fermentation bath temperature may further drop to the predetermined temperature TEMP. In particular, the driving time of the refrigeration cycle device 13 in the fermentation tank cooling control step S2000 is controlled by the drive time T3-T2 of the refrigeration cycle device 13 at the beginning of the aging temperature control step S2200, (T5-T4) of the refrigeration cycle apparatus 13 at the beginning of the operation (S2300).

That is, as the driving time of the refrigeration cycle apparatus 13 becomes longer, the remaining amount of cold heat after stopping the operation of the refrigeration cycle apparatus 13 is higher. Therefore, even if the temperature of the fermentation tank 13 It can be further lowered. 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 refrigeration cycle apparatus 13 is relatively short, The temperature of the fermenter can be lowered or minimized after the driving of the evaporator 13 is stopped.

In this case, the controller 281A can drive the heater 14 to raise the temperature of the fermentation tank. However, if the capacity of the heater 14 provided in the beverage maker is small, the rising speed of the fermentation tank temperature may be slow. When the fermentation tank temperature is lower than the lower limit value of the fermentation set temperature, the powdery yeast injected for the fermentation step is not smoothly activated. As the yeast can not be activated smoothly, the yeast growth and propagation may not be effectively performed and the fermentation step may not be performed normally. As a result, the quality of the taste and flavor of the manufactured beverage is lowered, and the user's satisfaction may be lowered.

To solve this problem, the beverage maker can adjust the fermenter temperature according to different standards according to the temperature control step shown in Fig. One embodiment related to this will be described with reference to FIGS. 8 to 9. FIG.

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

Referring to FIG. 8, the beverage maker can check whether the current temperature control step is the fermentation tank cooling control step (S2000) (S3000). If the present temperature control step is the fermentation tank cooling control step (YES in S3000), the beverage maker can drive the refrigeration cycle apparatus 13 (S3010).

In the fermentation tank cooling control step S2000, the controller 281A drives the refrigeration cycle device 13 to lower the temperature of the fermentation tank 13, have.

If the fermenter temperature is lower than the set temperature (fermentation set temperature) (YES in S3020), the beverage maker can stop driving the refrigeration cycle unit 13 (S3030).

The controller 281A can sense the fermenter temperature 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 value of the fermentation set temperature may be 20.5 ° C and the upper limit value of the fermentation set temperature may be 21.5 ° C.

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

On the other hand, when the current temperature control step is the control step S2100 (S2200) (S2300) except for the fermentation tank cooling control step S2000 (NO in S3000), the beverage maker sets the fermentation tank temperature to the set temperature It is possible to drive the refrigeration cycle apparatus 13 or the heater 14 to adjust the range between the upper limit value and the lower limit value.

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

Thereafter, the beverage maker stops the driving of the refrigeration cycle device 13 when the fermentation bath temperature reaches the difference between the set temperature and the margin value, that is, the lower limit value of the set temperature (or becomes lower than the lower limit value) (S3070).

That is, the controller 281A may stop driving the refrigeration cycle device 13 when the temperature of the fermentation tank reaches the lower limit value of the set temperature, unlike the step S3060 to S3020. 7, since the driving time of the refrigeration cycle device 13 is relatively short in comparison with the fermentation tank cooling control step S2000 in the aging temperature control step S2200 or the storage temperature control step S2300, The additional drop of the temperature of the fermentation tank by the freezing heat is also relatively small.

That is, in the case of the fermentation tank cooling control step S2000, the beverage maker controls to stop the driving of the refrigeration cycle device 13 under conditions different from the other steps S2100, S2200, S2300, It is possible to prevent the phenomenon that the yeast can not be smoothly activated.

Referring to FIG. 9, in contrast to the embodiment shown in FIG. 7, the controller 281A controls the temperature of the fermentation tank to be frozen at the time T1 when the fermentation tank temperature 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 fermentation tank temperature from becoming lower than the lower limit value ST1-M of the fermentation set point temperature. That is, the controller 281A can precisely control the fermentation tank temperature between the lower limit value ST1-M of the fermentation set point temperature and the upper limit value ST1 + M in the fermentation temperature control step S2100.

8, when the fermenter temperature is lower than the set temperature of the current temperature control step and the margin value, that is, the lower limit value of the set temperature (YES in S3080), the beverage maker sets the heater 14 to raise the fermenter temperature, (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, when it reaches the upper limit value of the set temperature (or becomes higher than the upper limit value) (YES in S3100) (S3110).

That is, the beverage maker can precisely control the temperature of the fermentation tank within the range between the lower limit value and the upper limit value of the set temperature, thereby preventing the beverage quality from deteriorating due to the temperature fluctuation.

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

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

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 can be increased. In this case, there is a possibility that the flow of the beverage is reduced, and the temperature of the beverage in the fermentation tank 112 is not uniform.

For example, during the operation of the refrigeration cycle apparatus 13, the descending rate of the fermentation tank temperature (or beverage temperature) around the refrigeration cycle apparatus 13 may be faster than the descending rate of the fermentation tank temperature around the temperature sensor 16. Accordingly, even if the temperature of the fermentation tank around the refrigeration cycle device 13 reaches the lower limit of the set temperature, the temperature of the fermentation tank around the temperature sensor 16 can be sensed higher than the lower limit of the set temperature. As a result, the refrigeration cycle device 13 is continuously driven, so that the beverage present around the refrigeration cycle device 13 is supercooled, and the quality of the beverage may be deteriorated.

10, when the fermenter temperature sensed by the temperature sensor 16 is higher than the sum of the set temperature of the present temperature control step and the first margin value, that is, the upper limit value of the set temperature (S4000 YES), the refrigeration cycle apparatus 13 can be driven to lower the fermentation tank temperature (S4010).

On the other hand, the beverage maker counts the driving time of the refrigeration cycle device 13, and compares the driving time with the reference time. The reference time may correspond to a predetermined time at the time of shipment of the product in order to prevent the supercooling by the refrigeration cycle device 13. [

If the driving time exceeds the reference time (YES in S4020), the beverage maker determines whether the fermenter temperature reaches a difference between the set temperature and the second margin value (or becomes lower than the difference between the set temperature and the second margin value) (YES in S4030), the driving of the refrigeration cycle unit 13 can be stopped (S4050).

On the other hand, if the drive time does not exceed the reference time (NO in S4020), the beverage maker determines whether the fermenter temperature reaches the difference between the set temperature and the first margin value, (YES in S4040), the driving of the refrigerating cycle apparatus 13 can be stopped (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. Thus, in step S4030, the controller 281A can stop driving the refrigeration cycle apparatus 13 when the fermenter temperature reaches a temperature value higher than the lower limit value of the set temperature.

That is, the beverage maker according to the embodiment of the present invention can adjust the temperature value for stopping the operation of the refrigeration cycle device 13 based on the comparison result of the driving time of the refrigeration cycle device 13 and the reference time . Specifically, when the driving time of the refrigeration cycle device 13 exceeds the reference time, the beverage maker determines that the temperature of the fermenter detected by the temperature sensor 16 is lower than the lower limit of the set temperature The driving of the refrigeration cycle unit 13 can be stopped.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.

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

The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
