CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application claims priority under 35 U.S.C. 119 and 35 U.S.C. 365 to Korean Patent Application No. 10-2019-0058389, filed in Korea on May 17, 2019, which is hereby incorporated by reference in its entirety.

BACKGROUND
1. Field

A beverage maker is disclosed herein.

2. Background

Beverages are collectively referred to as drinkable liquids, such as alcohol or tea. For example, beverages may be divided into various categories, such as water (a beverage) to solve thirst, juice beverages with unique flavor and taste, refreshing beverages giving a refreshing sensation, favorite beverages with an arousal effect, or alcoholic beverages with an alcohol effect.

Representative examples of such a beverage is beer. The beer is an alcoholic beverage made by making juice of malt sprouting from barley, filtering the juice, adding hop, and fermenting the juice using the yeast.

Consumers may purchase ready-made products made and sold by a beer maker or make beer at home (hereinafter “homemade” beer) by directly fermenting beer ingredients at home or in a bar. Homemade beer may be made in a variety of types and may be made to suit a consumer's taste.

The ingredients for making beer may include water, malt, hop, fermentation accelerators, and flavoring additives, for example. The fermentation accelerators, which are called yeast, may be added to malt to ferment the malt and help to produce alcohol and carbonic acid. The flavor additives are additives that enhance the taste of beer, such as fruit, syrup, and vanilla beans, for example.

Generally, homemade beer may include three stages or operations, namely, a wort stage or operation, a fermentation stage or operation, and an aging stage or operation, and it may take about two to three weeks from the wort stage or operation to the aging stage or operation. It is important for the homemade beer to maintain an optimum temperature during the fermentation operation, and the easier the beer is to make, the more user convenience is improved.

Recently, a beverage maker capable of easily making beer at home or in a bar has been gradually used. It is preferable that such a beverage maker be capable of safely and easily making beer.

The bypass check valve 324 may be disposed between the bypass valve 35 and the second main channel 42 with respect to the bypass channel 43.

Hereinafter, the ingredient supplier 3 will be described.

When beer is made using the beverage maker, the ingredients for making the beer may include a fluid, such as water, malt, a fermentation facilitator, for example, yeast, hop, and a flavouring additive, for example. The beverage maker may include both the ingredient supplier 3 and the fermentation container 12. The ingredients for making the beverage may be accommodated in and divided between the ingredient supplier and the fermentation container 12. A portion of the ingredients for making the beverage may be accommodated in the fermentation container 12, and the remaining ingredients may be accommodated in the ingredient supplier 3. The remaining ingredients accommodated in the ingredient supplier 3 may be supplied to the fermentation container 12 together with the fluid supplied from the fluid supply module 5 and mixed with the portion of the ingredients accommodated in the fermentation container 12.

A main ingredient which is essential for making a beverage may be accommodated in the fermentation container 12, and additives added to the main ingredient may be accommodated in the ingredient supplier 3. In this case, the additives accommodated in the ingredient supplier 3 may be mixed with the fluid supplied from the fluid supply module 5 and supplied to the fermentation container 12 and then may be mixed with the main ingredient accommodated in the fermentation container 12.

The main ingredient accommodated in the fermentation container 12 may have a capacity or amount greater than a capacity or amount of other ingredients. For example, when beer is made, the main material may be malt of the malt, the fermentation facilitator, the hop, and the flavouring additive. Also, the additives accommodated in the ingredient supplier 3 may be the other ingredient except for the malt of the ingredients for making the beer, for example, the fermentation facilitator, the hop, and the flavouring additive.

The beverage maker may not include the ingredient supplier 3 but may include only the fermentation container 12. In this case, the main ingredient may be accommodated in the fermentation container 12, and a user may directly put the additives into the fermentation container 12.

If the beverage maker includes both the ingredient supplier 3 and the fermentation container 12, the beverage may be more easily made. Hereinafter, a case in which the beverage maker includes both the ingredient supplier 3 and the fermentation container, will be described as an example. However, embodiments are not limited to the case in which the beverage maker includes both the ingredient supplier 3 and the fermentation container 12.

The ingredients within the fermentation container 12 may be fermented as time elapses, and the beverage made in the fermentation container 12 may flow to the second main channel 42 through the main channel connection portion 115 and also flow from the second main channel 42 to the beverage dispenser 6 so as to be dispensed. The ingredients necessary for making the beverage may be accommodated in the ingredient supplier 3, and the fluid supplied from the fluid supply module 5 may pass through ingredient supplier 3. For example, when the beverage made in the beverage maker is beer, the ingredients accommodated in the ingredient supplier 3 may be the fermentation facilitator, the hop, and the flavouring additive, for example.

The ingredients accommodated in the ingredient supplier 3 may be directly accommodated in the ingredient accommodation portions 31, 32, and 33 provided in the ingredient supplier 3. At least one ingredient accommodation portion 31, 32, and 33 may be provided in the ingredient supplier 3. Further, a plurality of ingredient accommodation portions 31, 32, and 33 may be provided in the ingredient supplier 3. In this case, the ingredient accommodation portions 31, 32, and 33 may be partitioned with respect to each other.

Inlets 31a, 32a, and 33a through which fluid may be introduced and outlets 31b, 32b, and 33b through which the fluid may be discharged may be provided in the ingredient accommodation portions 31, 32, and 33, respectively. The fluid introduced into the inlet of one ingredient accommodation portion may be mixed with ingredients within the ingredient accommodation portion and then discharged through the outlet.

The ingredients accommodated in the ingredient supplier 3 may be accommodated in ingredient containers C1, C2, and C3. In this case, the ingredient containers C1, C2, and C3 may be accommodated in the ingredient accommodation portions 31, 32, and 33, and each of the ingredient accommodation portions 31, 32, and 33 may be referred to as an “ingredient container mounting portion”.

The ingredient containers C1, C2, and C3 may each include a capsule or a pod; however, embodiments are not limited thereto. When the ingredients are accommodated in the ingredient containers C1, C2, and C3, the ingredient supplier 3 may be configured so that the ingredient containers C1, C2, and C3 are seated therein and withdrawn therefrom. The ingredient supplier 3 may be provided as an ingredient containers kit assembly in which the ingredient containers C1, C2, and C3 are separably accommodated.

For example, a first additive, a second additive, and a third additive may be accommodated in the ingredient supplier 3. The first additive may be the fermentation facilitator, the second additive may be the hop, and the third additive may be the flavouring additive. The ingredient supplier 3 may include a first ingredient container mounting portion 31 in which a first ingredient container C1 containing the first additive is accommodated, a second ingredient container mounting portion 32 in which a second ingredient container C2 containing the second additive is accommodated, and a third ingredient container mounting portion 33 in which a third ingredient container C3 containing the third additive is accommodated.

The ingredients contained in the ingredient accommodation portion or the ingredient containers C1, C2, and C3 may be extracted by a fluid pressure of the fluid supplied from the fluid supply module 5. When the ingredients are extracted by the fluid pressure, the fluid supplied from the fluid supply module 5 to the first main channel 41 may pass through the ingredient accommodation portion or the ingredient containers C1, C2, and C3 and then be mixed with the ingredients, and the ingredients accommodated in the ingredient accommodation portion or the ingredient containers C1, C2, and C3 may flow to the second main channel together with the fluid.

A plurality of additives different from each other may be accommodated separately in the ingredient supplier 3. For example, when beer is made, the plurality of additives accommodated in the ingredient supplier 3 may be the fermentation facilitator, the hop, and the flavouring additive, which may be accommodated separately from each other.

When the plurality of ingredient accommodation portions are provided in the ingredient supplier 3, the plurality of ingredient accommodation portions 31, 32, and 33 may be connected in series to each other in a flow direction of the fluid. That is, the ingredient supplier 3 may include at least one connecting channel 311 and 312 that connects the outlet of one ingredient accommodation portion of the plurality of ingredient accommodation portions 31, 32, and 33 to the inlet of another ingredient accommodation portion.

Further, the plurality of ingredient accommodation portions 31, 32, and 33 may include an initial ingredient accommodation portion 31 and a final ingredient accommodation portion 33. The plurality of ingredient accommodation portions 31, 32, and 333 may further include an intermediate ingredient accommodation portion 32.

The inlet 31a of the initial ingredient accommodation portion 31 may be connected to the first main channel 41, and the outlet 33b of the final ingredient accommodation portion 33 may be connected to the second main channel 42. The intermediate ingredient accommodation portion 32 may be disposed between the first ingredient accommodation portion 31 and the second ingredient accommodation portion 33 in the flow direction of the fluid. The inlet 32a and the outlet 32b of the intermediate ingredient accommodation portion 32 may be connected to the connecting channels 311 and 312 different from each other.

As illustrated in FIG. 1, when three ingredient accommodation portions are provided in the ingredient supplier 3, the outlet 31b of the final ingredient accommodation portion 31 may be connected to the inlet 32a of the intermediate ingredient accommodation portion 32 through the first connecting channel 311, and the outlet 32b of the intermediate ingredient accommodation portion 32 may be connected to the inlet 33a of the final ingredient accommodation portion 33 through the second connecting channel 312. In this case, the fluid introduced into the inlet 31a of the final ingredient accommodation portion 31 through the first main channel 41 may flow to the first connecting channel 311 through the outlet 31b together with the first additive accommodated in the initial ingredient accommodation portion 31.

The fluid (a mixture of the fluid and the first additive) introduced into the inlet 32a of the intermediate ingredient accommodation portion 32 through the first main channel 311 may flow to the second connecting channel 312 through the outlet 32b together with the second additive accommodated in the intermediate ingredient accommodation portion 32. The fluid (the mixture of the fluid and the first and second additives) introduced into the inlet 33a of the final ingredient accommodation portion 33 through the second main channel 312 may flow to the second connecting channel 42 through the outlet 33b together with the third additive accommodated in the final ingredient accommodation portion 33. The fluid (the mixture of the fluid and the first, second, and third additives) discharged through the second main channel 42 may be guided to the main channel connection portion 115 of the fermentation module 1 and then introduced into the fermentation container 12.

However, the configuration of the ingredient supplier 3 is not limited thereto. For example, when the intermediate ingredient accommodation portion is not provided, two ingredient accommodation portions may be provided in the ingredient supplier 3. In this case, one ingredient accommodation portion may be the initial ingredient accommodation portion, and the other ingredient accommodation portion may be the final ingredient accommodation portion. The outlet of the initial ingredient accommodation portion and the inlet of the final ingredient accommodation portion may be connected to each other by the connecting channel.

For another example, when a plurality of intermediate ingredient accommodation portions is provided, four or more ingredient accommodation portions may be provided in the ingredient supplier 3. In this case, one ingredient accommodation portion may be the initial ingredient accommodation portion, another ingredient accommodation portion may be the final ingredient accommodation portion, and the remaining ingredient accommodation portions may be intermediate ingredient accommodation portions. In this case, as the connection between the ingredient accommodation portions in series is easily understood by a person skilled in the art, their detailed descriptions has been omitted.

As the plurality of ingredient accommodation portions 31, 32, and 33 is connected in series to each other, a channel configuration of the ingredient supplier 3 may be simplified. Also, as additives contained in the ingredient containers C1, C2, and C3 are extracted at once, a time taken to extract the additives may decrease. Also, the ingredient supplier 3 may minimize fluid leakage points to improve reliability.

When the ingredients accommodated in the ingredient supplier 3 are accommodated in the ingredient containers C1, C2, and C3, the initial ingredient accommodation portion 31 may be referred to as an “initial ingredient container mounting portion”, the intermediate ingredient accommodation portion 32 may be referred to as an “intermediate ingredient container mounting portion”, and the final ingredient accommodation portion 33 may be referred to as a “final ingredient container mounting portion”.

Hereinafter, the fluid supply module 5 will be described.

The decompression component 60 may be disposed adjacent to the beverage dispensing valve 64.

The pressure of the beverage passing through the decompression component 60 may gradually decrease. The beverage passing through the decompression component 60 may be dispensed from the dispenser 62 and may not generate excessive bubbles.

When the beverage is dispensed, the beverage dispensing valve 64 may be opened. When the beverage is not dispensed, the beverage dispensing valve 64 may remain closed.

The dispenser 62 may include lever 620. When the user manipulates the lever 620, the beverage dispensing valve 64 may be opened, and when the lever 620 returns to its original position, the beverage dispensing valve 64 may be closed.

Hereinafter, the gas discharger 7 will be described.

The gas discharger 7 may be connected to the fermentation module 1 to discharge a gas generated in the fermentation container 12. The gas discharger 7 may include a gas discharge channel 71 connected to the fermentation module 1, a gas pressure sensor 72 installed in the gas discharge channel 71, and a gas discharge valve 73 connected to the gas discharge channel 71. The gas discharge valve 73 may be disposed behind or downstream of the gas pressure sensor 72 in a gas discharge direction.

The gas discharge channel 71 may be connected to the fermentation module 1, particularly, the fermentation lid 107. A gas discharge channel connection portion 121 to which the gas discharge channel 71 may be connected may be provided in the fermentation lid 107.

The gas within the fermentation container 12 may flow into the gas discharge channel 71 through the gas discharge channel connection portion 121. The gas pressure sensor 72 may detect a pressure of the gas discharged to the gas discharge channel 71 through the gas discharge channel connection portion 121 within the fermentation container 12.

The gas discharge valve 73 may be turned on to be opened when air is injected into the fermentation container 12 by the air injector 8. The beverage maker may uniformly mix the malt with the fluid by injecting the air into the fermentation container 12. Foam generated in the liquid malt may be discharged from an upper portion of the fermentation container 12 to the outside through the gas discharge channel 71 and the gas discharge valve 73. The gas discharge valve 73 may be opened or closed at least one time to detect fermentation during a fermentation process or operation.

The gas discharger 7 may further include a safety valve 75 connected to the gas discharge channel 71. The safety valve 75 may be disposed behind or downstream of the gas pressure sensor 72 with respect to the gas flow direction.

The safety valve 75 may restrict a maximum pressure of the fermentation container 12 and the gas discharge channel 71. For example, the safety valve 75 may restrict the maximum pressure of the fermentation container 12 and the gas discharge channel 71 to a pressure of about 3.0 bar.

The gas discharger 7 may further include a pressure release valve 76. The pressure release valve 76 may be connected to the gas discharge channel 71. The pressure release valve 76 and the gas discharge valve 73 may be selectively opened/closed. The pressure release valve 76 may be disposed behind or downstream of the gas pressure sensor 72 with respect to the gas flow direction.

A noise reducing device 77 may be mounted on the pressure release valve 76. The noise reducing device 77 may include at least one of an orifice structure or a muffler structure.

Even though the pressure release valve 76 is opened, an inner pressure of the fermentation container 12 may be gradually decreased by the noise reducing device 77. When fermentation of the beverage progresses, the pressure release valve 76 may be opened to release the pressure in a state in which the inner pressure of the fermentation container 12 increases. The noise reducing device 77 may effectively reduce noise generated due to a difference in pressure between the inside and outside of the fermentation container 12. The pressure release valve 76 may be opened/closed in the fermentation process or operation in which the inner pressure is relatively high.

Hereinafter, the air injector 8 will be described.

The air injector 8 may be connected to the fluid supply module 5 or the first main channel 41 to inject air. The air injector 8 may be connected to an opposite side of a sub channel 91, which will be described hereinafter, with respect to the heater 53.

In this case, air injected by the air injector 8 may pass through the heater 53 to flow to the sub channel 91 together with residual fluid within the heater 53. Thus, the residual fluid within the heater 53 may be removed to maintain a clean state of the heater 53.

Alternatively, air injected by the air injector 8 to the first main channel 41 may successively pass through the bypass channel 43 and the second main channel 42 and then be injected into the fermentation container 12. Thus, stirring or aeration may be performed in the fermentation container 12.

Alternatively, the air injected from the air injector 8 to the first main channel 41 may be guided to the ingredient supplier 3 to flow to the ingredient container mounting portions 31, 32, and 33. Residual fluid or residue within the ingredient containers C1, C2, and C3 or the ingredient container mounting portions 31, 32, and 33 may flow to the second main channel 42 by the air injected by the air injector 8 and then be discharged to the beverage dispenser 6. The ingredient containers C1, C2, and C3 and the ingredient container mounting portions 31, 32, and 33 may be cleanly maintained by the air injected by the air injector 8.

The air injector 8 may include an air injection channel connected to the fluid supply channel 55b or the first main channel 41 and air injection pump 82 connected to the air injection channel 81. An air injection check valve 83 that prevents the fluid within the fluid supply channel 55b from being introduced into the air injection pump 82 through the air injection channel 81 may be installed in the air injection channel 81.

The air injection pump 82 may pump the air to the air injection channel 81. A discharge portion of the air injection pump 82 may be connected to the air injection channel 81.

Air passing through an air filter 150 may be suctioned into a suction portion of the air injection pump 82. That is, the beverage maker may include air filter 150 and an air suction channel 152 connected to the air filter 150. A muffler 150a that reduces noise generated when the air is suctioned may be installed in the air suction channel 152.

The air suction channel 152 may be branched into a first suction channel 84 and a second suction channel 153. The first suction channel 84 may be connected to a suction portion of the air injection pump 82, and the second suction channel 153 may be connected to a suction portion of an air supply pump 151 described hereinafter. However, embodiments are not limited thereto, and thus, air passing through different filters may be suctioned into the suction portion of the air injection pump 82 and the suction portion of the air supply pump 151.

Hereinafter, the air controller 15 will be described.

The air controller 15 may control a pressure between the inner wall of the fermenter 112 and the outer surface of the fermentation container 12. The air controller 15 may supply air into the space between the fermentation container 12 and the fermenter 112. On the other hand, the air controller 15 may exhaust the air within the space between the fermentation container 12 and the fermenter 112 to the outside.

The air conditioner 15 may include air supply pump 151, an air supply channel 154 that connects the air supply pump 151 to the fermentation module 1, an exhaust channel 157 connected to the air supply channel 154 to exhaust air to the outside, and an exhaust valve 156 connected to the exhaust channel 157. The air supply pump 151 may inject air into the air supply channel 154. A discharge portion of the air supply pump 151 may be connected to the air supply channel 154, and a suction portion may be connected to the second suction channel 153 described above.

The air supply channel 154 may be connected to the fermentation module 1, particularly, the fermentation lid 107. An air supply channel connection portion 117 to which the air supply channel 154 may be connected may be provided in the fermentation module 1. The air supply channel connection portion 117 may communicate with the space between the inner wall of the fermenter 112 and the outer surface of the fermentation container 12.

The air injected from the air supply pump 151 to the air supply channel 154 may be guided between the outer surface of the fermentation container 12 and the inner wall of the fermenter 112. The air supplied into the fermenter 112 may press the fermentation container 12 between the outer surface of the fermentation container 12 and the inner wall of the fermenter 112.

The beverage within the fermentation container 12 may be pressed by the fermentation container 12 which is contracted by the air. When the main valve 40 and the beverage dispensing valve 64 are opened, the beverage may pass through the main channel connection portion 115 to flow to the second main channel 42. The beverage flowing from the fermentation container 12 to the second main channel 42 may be dispensed to the outside through the beverage dispenser 6.

The air supply pump 151 may supply air so that a predetermined pressure occurs between the fermentation container 12 and the fermenter 112. Thus, a pressure at which the beverage within the fermentation container 12 is easily dispensed may be occur between the fermentation container 12 and the fermenter 112.

The air supply pump 151 may be maintained in a turned-off state while the beverage is dispensed. When the beverage is completely dispensed, the air pump 82 may be driven for next beverage dispensing and then stopped. Thus, the beverage maker may dispense the beverage to the beverage dispenser 6 in a state in which the fermentation container 12 is disposed within the fermentation module 1 without withdrawing the fermentation container 12 to the outside of the fermentation module 1.

The exhaust channel 157 may function as an air exhaust passage, through which the air between the fermentation container 12 and the fermenter 112 may be exhausted to the outside, together with a portion of the air supply channel 154. The exhaust channel 157 may be disposed outside of the fermentation module 1. The exhaust channel 157 may be connected to a portion of the air supply channel 154, which is disposed outside of the fermenter 112.

The air supply channel 154 may include a first channel connected between the air supply pump 151 to a connection portion 157a, to which the exhaust channel 157 may be connected, and a second channel between a connection portion 154a, to which the exhaust channel 157 may be connected, and the air supply channel connection portion 117. The first channel may be an air supply channel that guides the air pumped by the air supply pump 151 to the second channel. Also, the second channel may be an air supply and exhaust-combined channel that supplies the air passing through the air supply channel into the space between the fermenter 112 and the fermentation container 12 or guides the air discharged from the space between the fermenter 112 and the fermentation container 12 to the exhaust channel 157.

The exhaust channel 157 may exhaust air therethrough. The exhaust valve 156 may be opened so that the air between the fermentation container 12 and the fermenter 112 may be exhausted to the outside when the fermentation container 12 is expanded while the beverage is made. The exhaust valve 156 may be opened when fluid is supplied by the fluid supply module 5. The exhaust valve 156 may be opened when air is injected by the air injector 8.

The exhaust valve 156 may be opened so that the air between the fermentation container 12 and the fermenter 112 may be exhausted when the beverage within the fermentation container 12 is completely dispensed. The user may take the fermentation container 12 out of the fermenter 112 when the beverage is completely dispensed. This is done because safety accidents occur when the inside of the fermenter 112 is maintained at a high pressure. The exhaust valve 156 may be opened when the beverage within the fermentation container 12 is completely dispensed.

The air controller 15 may further include an air restriction valve 159 that restricts the air pumped by the air supply pump 151 and supplied between the fermentation container 12 and the fermenter 112. The air restriction valve 159 may be a check valve.

The air restriction valve 159 may be installed in the air supply channel 154. That is, the air restriction valve 159 may be installed between the air supply pump 151 of the air supply channel 154 and the connection portion 157a of the exhaust channel 157.

Hereinafter, the sub channel 91 will be described.

The sub channel 91 may connect the fluid supply module 5 to the beverage dispenser 6. The sub channel 91 may have one or a first end 91a connected to the fluid supply channel 55b and the other or a second end 91b connected to the beverage dispensing channel 61.

The sub channel 91 may be connected between the pump 52 and the heater 53 with respect to the fluid supply channel 55b. The sub channel 91 may be connected to the connection portion 61a of the second main channel 42 and the beverage dispensing valve 64 with respect to the beverage dispensing channel 61.

The fluid supplied by the pump 52 and the air pumped by the air injection pump 82 may be guided to the beverage dispensing channel 61 through the sub channel 91 and then dispensed to the dispenser 62. Thus, residual fluid or beverage remaining in the beverage dispenser 6 may be removed.

A sub valve 92 that opens and closes the sub channel 91 may be installed in the sub channel 91. The sub valve 92 may be opened to open the sub channel 91 when the beverage is dispensed, or cleaning is performed.

A sub check valve 93 that prevents the beverage of the beverage dispensing channel 61 from flowing back to the fluid supply module 5 may be installed in the sub channel 91. The sub check valve 93 may be disposed between the sub valve 92 and the beverage dispensing channel 61 with respect to the sub channel 91.

The sub channel 91 may function as a residual fluid removing channel of the fluid supply module 5. For example, when the air injection pump 82 is turned on in a state in which the bypass valve 35 and the ingredient supply valve 310 are closed, the sub valve 92 is opened, the air injected into the air injection channel 81 may pass through the heater 53 to flow to the sub channel 91. Then, the air may pass through the sub valve 92 to flow to the beverage dispensing channel 61 and then be dispensed to the dispenser 62. In this process, the air may be dispensed together with the fluid supply module 5, more particularly, residual fluid remaining in the heater 53 and the fluid supply channel 55b so that residual fluid may be removed.

The sub channel 91 may also function as a cleaning channel. When a portion of the beverage is dispensed from the dispenser 62, and a long time has elapsed until the next dispensing, the dispenser 62 may be cleaned by allowing fluid to flow into the sub channel 91 before performing the next dispensing.

Hereinafter, the air removal module 50 will be described.

The pump 52 may include a gear pump. As the gear pump is used, a lubricant (grease) applied to a surface of an inner rotor and an inner wall of the pump may be gradually exhausted. Then, when used over a certain number of times, a pressure difference between an inlet and an outlet of the pump 52, which is generated by the gear pump, may gradually decrease. The inlet of the pump 52 may be connected to the tank discharge channel 55a, and the outlet may be connected to the fluid supply channel 55b.

The air removal module 50 may temporarily remove flow path resistance acting on the pump 52. That is, the air in the pump 52 may be removed by the air removal module 50, and instead, the fluid in the tank 51 may be introduced into the pump 52 by a head pressure. Thus, the pump 52 may smoothly supply fluid through the fluid supply channel 55b.

The air removal module 50 may include an air removal channel 50a and an air removal valve 50b connected to the air removal channel 50a. The air removal channel 50a may be connected to the fluid supply channel 55b. That is, the air removal channel 50a may be branched from the fluid supply channel 55b.

The air removal channel 50a may be connected to a point on the fluid supply channel 55b, which is adjacent to the pump 52. For example, the air removal channel 50a may be connected between the pump 52 and the heater 53 in the fluid supply channel 55b. In this case, the connection portion between the air removal channel 50a and the fluid supply channel 55b may be closer to the pump 52 than the heater 52.

The air removal valve 50b may include a solenoid valve. When the air removal valve 50b is opened, the air removal channel 50a may be opened, and air in the air removal channel 50a may be discharged to the outside through the air removal valve 50b. As a result, the air in the pump 52 may flow into the air removal channel 50a, and the fluid in the tank 51 may be introduced into the pump 52 by the head pressure.

The beverage maker may maintain the air removal valve 50b in a closed state when the pump 52 operates so that the fluid does not flow through the fluid supply channel 55b. In a state in which operation of the pump 52 is stopped, the air removal valve 50b may be opened. The beverage maker may allow the pump 52 to operate after the air removal valve 50b is opened for a predetermined period of time, and the air removal valve 50a is closed when the tank 51 is empty to refill the tank 51.

A support body 102 that supports the tank case 149 may be disposed on the base 100, and a first support portion or support 511 supported to contact the support body 102 may be disposed on the tank case 149.

The support body 102 may protrude upward from the base 100, and the first support 511 may protrude downward from the tank case 149. As the support body 102 and the first support 511 extend lengthwise vertically, a bottom surface of the tank case 149 may be spaced apart from the base 100.

A heater case 113 in which the heater 53 (see FIG. 1) may be accommodated may be installed on the base 100, and a second support portion or support 514 supported by the heater case 113 may be installed on the tank case 149.

The heater case 113 may extend lengthwise vertically, and the inner bottom surface of the tank case 149 may be spaced apart from the base 100. That is, one or a first side of the tank 51 may be supported by the support body 102 disposed on the base 100, and the other or a second side may be supported by the heater case 113.

A machine room 148 may be defined between the tank case 149 and the base 100. The machine room 148 may refer to a space between the tank case 149 and the base 100. Components, such as the pump 52, the air injection pump 82, and the compressor 131 may be disposed in the machine room 148.

The controller 284 may receive a measured value of at least one of the flow meter 56, the thermistor 54a, the fluid supply temperature sensor 57, the temperature sensor 16, or the gas pressure sensor 72. The controller 284 may detect an inner pressure of the fermentation container 12 by the gas pressure sensor 72 and detect a temperature of the fermenter 112 by the temperature sensor 16. The control module 280 may determine a degree of fermentation of the beverage using the detected pressure or temperature.

The controller 284 may detect a temperature of fluid supplied from the fluid supply module 5 to the first main channel 41 using the fluid supply temperature sensor 57. The controller 284 may control the heater 53 according to the detected temperature of the fluid. The controller 284 may control the temperature controller 11 to maintain the temperature of the fermenter 112 at an adequate temperature.

The controller 284 may accumulate at least one of a time taken to open the dispenser 62, a time taken to drive the air supply pump 151, and a time taken to turn on the main valve 40 after the beverage is completely made, for example. The controller 284 may calculate an amount of dispensed beverage dispensed from the fermentation container 12 according to the accumulated time. The controller 284 may calculate an amount of residual beverage from the calculated amount of dispensed beverage. The controller 284 may determine whether the beverage within the fermentation container 12 is completely dispensed from the calculated amount of residual beverage. The controller 284 may determine that the beverage is completely dispensed when it is determined that the beverage within the fermentation container 12 is completely dispensed. In addition, the controller 284 may control an overall operation of the beverage maker.

The beverage maker may further include a condenser case 130. The condenser case 130 may be disposed on the base 100 and may accommodate the condenser 132.

The first fluid level scale 511a may be displayed on an outer surface of the curved portion 511 of the tank 51. The first fluid level scale 511a may be directed forward when viewed from a front side. Thus, the user may easily check an amount of fluid contained in the tank 51 by looking at the first fluid level scale 511a in a state in which the tank 51 is separated from the tank case 149.

The second fluid level scale 512a may be displayed on a rear surface of the tank 51, that is, on the outer surface of the flat portion 512. The second fluid level scale 512a may be directed forward when viewed from the front side. That is, the second fluid level scale 512a may be appear upside down when viewed from the rear side.

The user may view the second fluid level scale 512a from the front side through the transparent or translucent curved portion 511 while the tank 51 is accommodated in the tank case 149, and also the user may easily check an amount of fluid contained in the tank 51 by viewing the second fluid level scale 512a.

In order to allow visibility of the second fluid level scale 511a to increase in a state in which the tank 51 is accommodated in the tank case 149, a color of the second fluid level scale 511a may be contrasted with a color of the inner circumference of the tank case 149.

The inclined portion 514 may be inclined in a direction in which a height thereof decreases toward the inside. As the inclined portion 514 has a diameter that gradually decreases toward the lower side, a diameter of the lower rib 513 may be less than a diameter of the outer circumference of the tank 51. The diameter of the outer circumference of the tank 51 may refer to a diameter of the curved portion 511.

The lower rib 513 may be guided by a guide rib 602 disposed on the tank case 149 (see FIG. 15). When the user puts the tank 51 into the tank case 149, a lower end of the lower rib 513 may be slid down along an inclined upper end of the guide rib 602, and the lower rib 513 may move to the inside of the guide rib 602. Thus, the tank 51 may be mounted in place in the tank case 149.

When the lower rib 513 moves inside of the guide rib 602, the inclined portion 514 of the tank 51 may be disposed above the guide rib 602. That is, the guide rib 602 and the tank 51 may not interfere with the inclined portion 514.

At least one hook groove 513a may be defined in the lower rib 513. The hook groove 513a may be cut out in the lower rib 513. Ends of the hook groove 513a may be inclined in a direction in which the ends are close to each other toward an upper side.

The handle seating portion 522 may be stepped downward with respect to a top surface of the lid seating body 520. An upper end of the handle 540 seated on the handle seating portion 522 may be disposed on the top surface and a horizontal surface of the lid seating body 520.

A rotational direction of the handle 540 and the tank lid 530 may be opposite to each other. For example, the handle 540 may rotate forward to be separated from the handle seating portion 522 and also rotate backward to be seated on the handle seating portion 522. On the other hand, the tank lid 530 may rotate backward to be opened and rotate forward to be closed.

A space 541 may be defined between the connection portion 532 of the tank lid 530 and the handle 540. The space 541 may be stepped downward with respect to a top surface of the tank lid 530 and a top surface of the handle 540, and a bottom surface of the space 541 may be blocked.

The user may rotate the handle 541 upward by putting a finger into the space 541. The user may allow the handle 541 to easily rotate upward in a state in which the tank 51 is accommodated in the tank case 149 and also may hold the handle 541 which has been rotated upward to take the tank 51 out of the tank case 149.

FIG. 15 is a cross-sectional view of an inside of the tank and the tank case according to an embodiment. FIG. 16 is a view of a bottom surface of the tank according to an embodiment. FIG. 17 is a view illustrating the inside of the tank case when viewed from the upper side according to an embodiment. FIG. 18 is a view for explaining an operation of a fluid leakage prevention valve according to an embodiment. FIG. 19 is a view illustrating a state in which the fluid leakage prevention valve is opened according to an embodiment.

The tank 51 may be separably accommodated in the tank case 149. The user may insert the tank 51 from the upper side of the tank case 149 into the tank case 149.

The tank case 149 may be provided with a configuration for mounting the tank 51 in place. For example, the tank case 149 may be provided with mounting guide 601, guide rib 602, and protrusion 603.

The mounting guide 601 may be provided on an inner circumference of the tank case 149. The mounting guide 601 may contact the flat portion 512 of the tank 51. The mounting guide 601 may be disposed behind the tank 51. The mounting guide 601 may guide the tank 51 to be mounted in the tank case 149 only in a predetermined direction. Also, the tank 51 may not rotate within the tank case 149 due to the mounting guide 601.

The guide rib 603 may protrude upward from the bottom surface of the tank case 149. The guide rib 603 may be connected to the inner circumference of the tank case 149. An upper end of the guide rib 603 may be inclined in a direction in which a height thereof gradually decreases toward the inside.

As described above, the lower rib 513 of the tank 51 may move down along the upper end of the guide rib 602 and then move inside of the guide rib 602. Thus, the guide rib 603 may be disposed outside of the lower rib 513 of the tank 51 and be disposed below the inclined portion 514.

A plurality of guide ribs 602 may be provided. The plurality of guide ribs 602 may be spaced apart from each other in the circumferential direction of the tank case 149 or the lower rib 513.

Also, the protrusion 603 protruding upward from the bottom surface of the tank case 149 may be disposed on the tank case 149. The protrusion 603 may be hooked with the hook groove 513a defined in the lower rib 513 of the tank 51. As ends of the hook groove 513a are inclined in a direction in which the ends are close to each other toward the upper side, the protrusion 603 may be guided by the ends of the hook groove 513a and then inserted up to the end of the hook groove 513a.

The protrusion 603 may be disposed inside of the guide rib 602. In a state in which the lower rib 513 of the tank 51 is disposed inside of the guide rib 602, the protrusion 603 may be hooked with the hook groove 513a of the lower rib 513.

The tank 51 may be provided with a fluid leakage prevention valve 535 that blocks the discharge hole 515. A hollow portion 516 that protrudes downward from the bottom surface of the tank 51 and communicating with the discharge hole 515 may be defined in the tank 51, and the fluid leakage prevention valve 535 may be mounted within the hollow portion 516. The hollow portion 516 may be disposed inside of the lower lid 513.

The fluid leakage prevention valve 535 may have a cylindrical shape that extend lengthwise vertically. The fluid leakage prevention valve 535 may be mounted on the hollow portion 516 so as to be elevatable. When the tank 51 is mounted on the tank case 149, the fluid leakage prevention valve 535 may be pressed upward by a pressing protrusion 606 described hereinafter, and the discharge hole 515 may be opened. On the other hand, when the tank 51 is separated from the tank case 149, the fluid leakage prevention valve 535 may descend by elastic force of an elastic member 519 described hereinafter, and the discharge hole 515 may be blocked.

An insertion portion 604 into which the hollow portion 516 may be inserted may be defined in the bottom surface of the tank case 149. The insertion portion 604 may protrude upward from the inner bottom surface of the tank case 149. The insertion portion 604 may have an approximately annular shape.

An outlet 605 that communicates with an inside of the insertion portion 604 and connected to the tank discharge channel 55a (see FIG. 1) may be disposed in the tank case 149. The outlet 605 may have a hollow shape that communicates with an inside of the insertion portion 604 and protrudes to a lower side of the tank case 149.

The pressing protrusion 606 that presses the fluid leakage prevention valve 535 of the tank 51 upward may be disposed inside of the insertion portion 604. The pressing protrusion 606 may be disposed above the outlet 605 and be connected to the outlet 605. The pressing protrusion 606 may have a size that does not block the outlet 605. When the tank 51 is mounted on the tank case 149, the pressing protrusion 606 may press the fluid leakage prevention valve 535 of the tank 51 upward, and the discharge hole 51 of the tank 51 may be opened so that the fluid of the tank 51 may flow to the tank discharge channel 55a (see FIG. 1).

A valve guide rib 515a that guides elevation of the fluid leakage prevention valve 535 may be disposed on the tank 51. The valve guide rib 515a may protrude upward from the bottom surface of the tank 51. The valve guide rib 515a may be connected to the upper end of the discharge hole 515. A plurality of valve guide ribs 515a spaced apart from each other in a circumferential direction of the outlet port 515 may be provided. However, embodiments are not limited thereto. For example, the valve guide rib 515a may have a single ring shape surrounding an upper side of the discharge hole 515.

An inside of the hollow portion 516 of the tank 51 may be provided with elastic member 519 that presses the fluid leakage prevention valve 535 downward. The elastic member 519 may be a coil spring that is biased to apply elastic force downward and disposed to surround a periphery of the fluid leakage prevention valve 535.

An expansion portion 532 pressed by the elastic member 519 may be disposed on the fluid leakage prevention valve 535. The expansion portion 532 may be expanded in a radially outward direction from a periphery of the fluid leakage prevention valve 535. The expansion portion 532 may be disposed around a lower end of the fluid leakage prevention valve 535. The elastic member 519 may be compressed/tensioned between a periphery of a lower end of the discharge hole 515 and the extension portion 532.

The fluid leakage prevention valve 535 may be provided with an inner O-ring 518 that blocks between an outer circumference of the fluid leakage prevention valve 535 and an inner circumference of the discharge hole 515. That is, an O-ring fitting groove 531 in which the inner O-ring 518 may be mounted may be defined in the fluid leakage prevention valve 535. The O-ring fitting groove 531 may be defined in an upper outer circumference of the fluid leakage prevention valve 535 and extend lengthwise in the circumferential direction of the fluid leakage prevention valve 535.

An inner diameter of the discharge hole 515 of the tank 51 may gradually decrease downward. When the fluid leakage prevention valve 535 descends due to the elastic force of the elastic member 519, the inner O-ring 518 may contact the inner circumference of the discharge hole 515 to block the discharge hole 515. The fluid leakage prevention valve 535 may prevent the fluid of the tank 51 from leaking to the discharge hole 515.

When the tank 51 is mounted in place in the tank case 149, the hollow portion 516 may be inserted into the insertion portion 604, and the pressing protrusion 606 may be inserted into the hollow portion 516 to press the fluid leakage prevention valve 535 upward. When the fluid leakage prevention valve 535 ascends by the pressing protrusion 606, the inner 0-ring 518 may be spaced apart from the inner circumference of the discharge hole 515. The fluid of the tank 51 may flow between the inner circumference of the discharge hole 515 and the inner O-ring 518 by gravity to flow into the hollow portion 516. The fluid flowing into the hollow portion 516 may pass between the inner circumference of the hollow portion 516 and the outer circumference of the fluid leakage prevention valve 535 to flow into the insertion portion 604 of the tank case 149. The fluid flowing into the insertion portion 604 of the tank case 149 may pass through the outlet 605 to flow to the tank discharge channel 55a (see FIG. 1).

The hollow portion 516 may be provided with an outer O-ring 517 that blocks between the outer circumference of the hollow portion 516 and the inner circumference of the insertion portion 604. The hollow portion 516 may have an O-ring fitting groove 516a in which the outer 0-ring 517 may be mounted. The 0-ring fitting groove 516a may be defined in a lower outer circumference of the hollow portion 516 and may extend lengthwise in the circumferential direction of the hollow portion 516. The outer O-ring 517 may prevent the fluid passing through the hollow portion 516 from leaking between the hollow portion 516 and the insertion portion 604.

FIG. 20 is a view for explaining a coupling relationship between the tank body and the lid seating body according to an embodiment. A packing 526 may be mounted on the lid seating body 520. The packing 526 may be mounted under the lid seating body 520. The packing 526 may have a ring shape corresponding to the lid seating body 520.

A first upper rib 523 and a second upper rib 524 may be disposed on the lid seating body 520. The first upper rib 523 and the second upper rib 524 may protrude downward from the lid seating body 520. Each of the first upper rib 523 and the second upper rib 524 may have an annular shape that extends lengthwise in the circumferential direction of the lid seating body 520.

An outer surface of the second upper rib 524 may be continuously connected to the outer circumference of the lid seating body 520 without being stepped. The second upper rib 524 may be spaced apart from the first upper rib 523 in a radially outward direction, and the packing 526 may be fitted between the second upper rib 524 and the first upper rib 523.

The lid seating body 520 may be coupled, for example, fused to a top end of the main body 510. The packing 526 may prevent the fluid from leaking between the main body 510 and the lid seating body 520, which are coupled, for example, fused to each other.

The lid seating body 520 may be coupled, for example, fused to the top end of the main body 510 in a state in which the packing 526 is mounted. Thus, the packing 526 may be disposed between the lid seating body 520 and the main body 510 and may not be visible from the outside.

The main body 510 may include a first lower rib 510a and a second lower rib 510b. The first lower rib 510a and the second lower rib 510b may be disposed on the upper end of the main body 510. The second lower rib 510b may be spaced apart from the first lower rib 510a in a radially outward direction.

The first lower rib 510a may contact the first upper rib 523. An upper end of the first lower rib 510a may contact a lower end of the first upper rib 523. In this case, the packing 526 may contact the first lower rib 510a to close a gap between the first lower rib 510a and the first upper rib 523. Therefore, the fluid inside of the tank 51 may be prevented from being introduced between the first lower rib 510a and the first upper rib 523.

The second lower rib 510b may be coupled, for example, fused to the second upper rib 524. A fused (coupled) portion 527 that is coupled, for example, fused with the second lower rib 510b may be disposed on the second upper rib 524. The fused portion 527 may protrude downward from an inner end of the second upper rib 524. The fused portion 527 may have a ring shape like the second upper rib 524.

A fused mountain may be disposed on the second upper rib 524 before the lid seating body 520 is fused to the main body 510. In a process in which the lid seating body 520 is fused with the main body 510, the fused mountain may be melted to form the fused portion 524. Thus, the second lower rib 510b and the second upper rib 524 may be fused to each other.

An upper protrusion 525 may be disposed on the second upper rib 524, and a lower protrusion 510c that contacts the upper protrusion 525 may be disposed on the second lower rib 510b. The upper protrusion 525 may protrude downward from the second upper rib 524. An outer surface of the upper protrusion 525 may be continuously connected to an outer circumference of the second upper rib 524.

The lower protrusion 510c may protrude upward from the second lower rib 510b. An outer surface of the lower protrusion 510c may be continuously connected to an outer circumference of the second lower rib 510b.

The upper protrusion 525 may be disposed above the lower protrusion 510c, and a lower end of the upper protrusion 525 may contact an upper end of the lower protrusion 510c. The upper protrusion 525 and the lower protrusion 510c may cover the fused portion 527 from the outside. The upper protrusion 525 and the lower protrusion 510c may prevent the melted fused mountain from being separated to the outside of the tank 51 in the process of forming the fused portion 527.

According to embodiments disclosed herein, the lower end of the lower rib may be slid along the upper end of the guide rib, and the lower rib may be guided to the inside of the guide rib. Therefore, the tank may be mounted in place on the tank case.

The protrusion piece may be hooked with the hook groove so that the tank is mounted in place on the tank case, and the tank may be fixed so as not to rotate inside of the tank case. As ends of the hook groove may be inclined in the direction, in which the ends are close to each other, toward the upper side, the protrusion may be guided by both the ends of the hook groove and inserted up to the end of the hook groove.

As the hollow portion of the tank is inserted into the insertion portion of the tank case, the fluid in the tank may flow through the hollow portion and the inside of the insertion portion to flow to the tank discharge channel. The discharge hole may have an inner diameter that gradually decreases downward. As a result, the lower end of the lower rib may slide along the upper end of the guide rib, and the lower rib may be guided to the inside of the guide rib.

In addition, the O-ring may be provided between the outer circumference of the hollow portion and the inner circumference of the insertion portion. Thus, the fluid may not leak between the outer circumference of the hollow portion and the inner circumference of the insertion portion. As the fluid leakage prevention valve is normally pressed downward by the elastic member, the fluid may not leak from the tank.

The pressing protrusion of the tank case may press the fluid leakage prevention valve upward. Thus, when the tank is mounted on the tank case, the discharge hole of the tank may be opened.

Elevation of the fluid leakage prevention valve may be guided by the valve guide rib. The 0-ring may be provided between the outer circumference of the fluid leakage prevention valve and the inner circumference of the discharge hole. Thus, the fluid leakage prevention valve may reliably close the discharge hole.

The inclined portion of the tank may have a diameter that gradually decreases downward and be disposed above the guide rib. Thus, the guide rib may not interfere with the tank, and the tank may be mounted in place in the tank case.

The mounting guide may contact the flat portion of the tank in the tank case. Thus, the tank may be mounted on the tank case with directivity.

The fluid level scale that is directed in the forward direction when viewed from the front may be displayed on the outer surface of the flat portion. This allows the user to check the fluid level immediately without removing the tank from the tank case.

The color of the fluid level scale may be contrasted with the color of the inner circumference of the tank case. Thus, visibility of the fluid level scale may be improved.

The packing may be disposed between the main body and the lid seating body. Thus, fluid may not leak between the main body and the lid seating body, and the tank may be reliably sealed.

As the main body and the lid seating body are coupled to each other in a fusion manner, even if a size of the tank is large, it may be easily coupled, and a coupling strength may be improved.

The handle may be disposed to surround a portion of the outer circumference of the tank lid, and the connection portion between the tank lid and the lid seating body may be disposed inside of the handle. A rotational direction of the tank lid and the handle may be reversed. Thus, the tank lid and the opening of the corresponding tank may be provided to be sufficiently large, and thus, the user may easily clean the inside of the tank.

The upper protrusion and the lower protrusion may cover the fusion portion from the outside. As a result, in a process of fusing the main body and the lid seating body, the melted fused mountain may not leak out of the tank, and the fused portion may not be visible from the outside.
