Description

Beverage maker {BAVERAGE MAKER}

The present invention relates to a beverage maker, and more particularly, to a beverage maker for producing a fermented beverage.

Beverage is a general term for drinkable liquids such as alcohol and tea. For example, beverages are classified into various categories such as water (beverage) to quench thirst, fruit drinks with unique aromas and tastes, soft drinks that give a refreshing feeling, favorite drinks that can be expected to wake up, or alcoholic drinks with alcohol effects. It can be.

A typical example of such a beverage is beer. Beer is an alcoholic beverage made by making juice from malt (malt) made from sprouted barley, filtering it, adding hops, and fermenting it with yeast.

Consumers can purchase ready-made products manufactured and sold by beer manufacturers, or drink house beer (or craft beer) produced by directly fermenting beer ingredients at home or in a bar.

House beer can be manufactured in a variety of types rather than ready-made beer, and can be manufactured to suit consumer tastes.

Materials for making beer may be water, malt, hops, yeast, flavor additives, and the like.

Yeast may be called yeast, and may be added to malt to ferment the malt and help produce alcohol and carbonic acid.

Flavoring additives are additives that enhance the taste of beer, such as fruit, syrup, or vanilla beans.

Typically, house beer may include a total of three stages of wort production, fermentation, and maturation, and it may take about 2 to 3 weeks from wort production to maturation.

It is important to maintain the optimal temperature during the fermentation step of house beer, and user convenience can be increased as it is simply produced.

Recently, a beverage maker that can easily prepare house beer at home or in a bar is gradually being used, and it is desirable that such a beverage maker safely and conveniently prepares beer.

One problem to be solved by the present invention is to provide a beverage maker in which the temperature of the fermenter can be maintained uniformly.

Another problem to be solved by the present invention is to provide a beverage maker capable of accurately measuring the temperature of the fermenter.

Beverage maker according to an embodiment of the present invention, the base; A fermenter disposed above the base; Fermentation leads for opening and closing the fermentation tank; Refrigeration cycle device including an evaporator wound around the outer circumference of the fermentation tank; a heater disposed below the fermenter; And it may include a temperature sensor disposed in the fermentation tank to measure the temperature of the fermentation tank. A first height between the base and the temperature sensor may be higher than a second height between the base and the heater, and may be lower than a third height between the base and the evaporator.

A difference between the first height and the second height may be smaller than a difference between the first height and the third height.

The heater may be a plate heater attached to the bottom outer surface of the fermenter.

The temperature sensor may be attached to an outer circumference of the fermenter.

A fermentation case supported by the base and accommodating the fermentation tank may be further included. The outer circumference and outer bottom surface of the fermentation tank may be spaced apart from the inner surface of the fermentation case.

The evaporator may be spaced apart from the inner circumference of the fermentation case, and the heater may be spaced apart from the inner bottom surface of the fermentation case.

The temperature sensor may be located between the inner circumference of the fermentation case and the outer circumference of the fermentation tank.

The fermentation tank is formed with a support for supporting a fermentation container accommodated inside the fermentation tank, and when the fermentation container is expanded, at least a part of an outer surface of the fermentation container may come into contact with an inner wall of the fermentation tank.

At least one rib is formed on the inner wall of the fermentation tank to separate the outer surface of the fermentation container and the inner wall of the fermentation tank, and the height between the base and the top of the evaporator is lower than the height between the base and the rib.

A controller for selectively controlling the refrigerating cycle device and the heater based on the temperature measured by the temperature sensor may be further included.

According to a preferred embodiment of the present invention, since the heater is located on the bottom of the fermenter, natural convection may occur as the content heated by the heater rises. In addition, since the evaporator wound around the fermenter is located at a relatively upper side, the content cooled by the evaporator descends and natural treatment may occur. This allows the fermenter to be heated evenly.

In addition, the height of the temperature sensor attached to the fermenter may be higher than the heater and lower than the evaporator based on the base. Accordingly, erroneous measurements caused by overheating or supercooling of the contents are minimized, and representative temperature values of the fermenter can be accurately measured.

In addition, since the beverage sensor is disposed on the outer circumference of the fermentation tank rather than the bottom surface, erroneous measurements caused by contents accumulated on the lower side of the fermentation tank or fermentation container are minimized, and the representative temperature value of the fermentation tank can be accurately measured.

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 higher than the previous 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 from 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.

If a considerable time interval exists between the completion of the last beverage dispensing process and the next beverage dispensing process, there is a concern that the inside of the dispenser 62 may be contaminated by the beverage remaining in the dispenser 62.

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, the water may be removed together with the dregs and foreign substances inside the dispenser 62 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 can be taken out together with residual water remaining inside the dispenser 62 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 can flow through the bypass valve 35 to 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 channel, 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.

5 is an enlarged view of the fermenter module shown in FIG. 1;

As described above, the fermentation vessel module 111 may include a fermentation case 160, a fermentation vessel 112, and a lid seating body 179.

The fermentation case 160 may be supported by the base 100 and may accommodate the fermentation vessel 112 . The lid seating body 179 is disposed on the upper side of the fermentation tank 112, and the fermentation lid 170 (see FIG. 1) is seated on the lid seating body 179 to seal the fermentation tank 112.

The outer circumference and outer bottom surface of the fermentation tank 112 may be spaced apart from the inner surface of the fermentation case 160. A heat insulating unit may be provided between the fermentation case 160 and the fermentation tank 112 . The insulator may surround the evaporator 134 and the heater 14 together with the fermenter 112 . As a result, the temperature of the fermenter 112 cooled or heated by the evaporator 134 and the heater 14 can be maintained.

At least one rib 114 may be formed on the inner surface of the fermenter 112. The rib 114 may protrude from the inner upper part of the fermentation tank 112. The rib 114 may be formed long in the vertical direction. A plurality of ribs 114 may be formed spaced apart from each other by a predetermined interval along the circumferential direction of the fermentation tank 112.

Meanwhile, a support 112A supporting the fermentation container 12 may be formed in the fermentation tank 112 . The fermentation container 12 may be accommodated inside the fermentation tank 12 while being supported by the support 112A of the fermentation tank 112 .

The fermentation container 12 may generate gas as fermentation of the material proceeds, and may be expanded by the gas therein. At this time, the rib 114 may allow the fermentation container 12 formed of a flexible material to expand evenly.

In addition, the rib 114 may separate the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112. During the beverage dispensing process, air supplied from the air supply channel (154, see FIG. 1) may flow between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112, and a plurality of ribs formed on the inner wall of the fermentation tank 112 114 may help smooth flow of air supplied from the air supply channel 154 into the fermenter 112.

An evaporator 134 for cooling the fermentation tank 112 may be wound around the outer circumference of the fermentation tank 112 . In more detail, the evaporator 134 may be wound around an upper part of the outer circumference of the fermentation tank 112. The evaporator 134 may be located between the inner circumference of the fermentation case 160 and the outer circumference of the fermentation tank 112 .

Since the mixture cooled by the evaporator 134 descends due to the increase in density, the mixture (eg, beverage before fermentation) in the fermenter 112 can be evenly cooled.

The evaporator 134 may be spaced apart from the inner circumference of the fermentation case 160 and may be covered together with the fermentation tank 112 by an insulator. As a result, the cooling effect of the fermentation tank 112 by the evaporator 134 can be increased, and the temperature drop of the fermentation case 160 can be minimized.

In addition, a heater 14 for heating the fermentation tank 112 may be disposed below the fermentation tank 112 . The heater 14 may be positioned between the inner bottom surface of the fermentation case 160 and the outer bottom surface of the fermentation tank 112 . The heater 14 may include a plate heater attached to the bottom outer surface of the fermenter 112.

Since the mixture heated by the heater 14 rises due to the decrease in density, the mixture in the fermenter 112 (eg, beverage before fermentation) can be evenly heated.

The heater 14 may be spaced apart from the inner bottom surface of the fermentation case 160 and may be covered together with the fermentation tank 112 by a heat insulating unit. As a result, the heating effect of the fermentation tank 112 by the heater 14 can be increased, and the temperature rise of the fermentation case 160 and the base 100 can be minimized.

Meanwhile, a temperature sensor 16 for sensing the temperature of the fermentation tank 112 may be disposed on the outer surface of the fermentation tank 112 .

The temperature sensor 16 preferably measures a representative temperature value inside the fermenter. However, if the temperature sensor 16 is located on the bottom of the fermenter, since the mixture is piled on the bottom of the fermenter 112, the temperature sensor 16 may have a problem in that it may be difficult to measure an accurate temperature value inside the fermenter 112. . Therefore, the temperature sensor 16 may be attached to the outer surface of the fermenter 112 rather than to the bottom surface. In more detail, the temperature sensor 16 may be disposed on the lower side of the outer circumference of the fermenter 112.

Since the heater 14 is disposed on the bottom surface of the fermentation tank 112, the first height H1 between the base 100 and the temperature sensor 16 is the second height between the base 100 and the heater 14 ( H2) may be higher.

Also, the first height H1 between the base 100 and the temperature sensor 16 may be lower than the third height H3 between the base 100 and the evaporator 134 .

That is, in the vertical direction with respect to the base 100, the height of the temperature sensor 16 may be between the height of the heater 14 and the height of the evaporator 134. Thus, the temperature sensor 16 can easily measure the representative temperature inside the fermenter 112 .

The fermentation container 12 shown in FIG. 5 is shown in an unexpanded state, and the fermentation container 12 may be expanded until the outer surface contacts the inner wall of the fermenter 112. However, the portion of the inner wall of the fermentation tank 112 where the rib 114 is formed may be spaced apart from the inner wall of the fermentation tank 112 by the rib 114.

With respect to the radial direction of the fermenter 112, the ribs 114 and the evaporator 134 may not overlap. A height H4 between the base 100 and the top of the evaporator 134 may be lower than a height H5 between the base 100 and the rib 114 .

Therefore, when the fermentation container 12 is inflated, a portion of the outer surface of the fermentation container 12 corresponding to the position of the evaporator 134 is in contact with the inner surface of the fermentation tank 12 so that the distance to the evaporator 134 can be minimized. In this way, the beverage or mixture contained in the fermentation container 12 can be easily cooled by the evaporator 134.

Since both the evaporator 134 and the temperature sensor 16 are located on the outer circumference of the fermenter, if the temperature sensor 16 is too close to the evaporator 134, the temperature sensor ( The temperature measured in 16) may be lower than the actual temperature of the fermentation tank 12. On the other hand, since the temperature sensor 16 is located on the outer surface of the fermentation tank 112 and the heater 14 is located on the bottom of the fermentation tank 112, a minimum distance between the heater 14 and the temperature sensor 16 can be maintained. can

Therefore, the difference (H1-H2) between the first height (H1) and the second height (H2) is smaller than the difference (H3-H1) between the first height (H1) and the third height (H3). can That is, in the vertical direction with respect to the base 100, the height of the temperature sensor 16 may be closer to the height of the heater 14 than the height of the evaporator 134.

Meanwhile, the fermentation case 160 may include an upper case body 160A and a lower case body 160B.

The upper case body 160A and the lower case body 160B may be integrally formed. The upper case body 160A may constitute the upper exterior of the fermentation case 160, and the lower case body 160B may constitute the lower exterior of the fermentation case 160.

The inner diameter of the upper case body 160A may be larger than that of the lower case body 160B. At this time, the evaporator 134 wound around the fermentation tank 112 may overlap the upper case body 160A in the radial direction of the fermentation case 160, and may not overlap the lower case body 160B.

Thus, a sufficient distance can be secured between the evaporator 134 and the inner surface of the fermentation case 160, so that the temperature drop of the fermentation case 160 can be minimized.
