Description:
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. 10-2019-0056408, filed in Korea on May 14, 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&#39;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.

     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 flavoring 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 flavoring 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 flavoring 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 flavoring 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  31   a ,  32   a , and  33   a  through which fluid may be introduced and outlets  31   b ,  32   b , and  33   b  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 C 1 , C 2 , and C 3 . In this case, the ingredient containers C 1 , C 2 , and C 3  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 C 1 , C 2 , and C 3  may each include a capsule or a pod; however, embodiments are not limited thereto. When the ingredients are accommodated in the ingredient containers C 1 , C 2 , and C 3 , the ingredient supplier  3  may be configured so that the ingredient containers C 1 , C 2 , and C 3  are seated therein and withdrawn therefrom. The ingredient supplier  3  may be provided as an ingredient containers kit assembly in which the ingredient containers C 1 , C 2 , and C 3  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 flavoring additive. The ingredient supplier  3  may include a first ingredient container mounting portion  31  in which a first ingredient container C 1  containing the first additive is accommodated, a second ingredient container mounting portion  32  in which a second ingredient container C 2  containing the second additive is accommodated, and a third ingredient container mounting portion  33  in which a third ingredient container C 3  containing the third additive is accommodated. 
     The ingredients contained in the ingredient accommodation portion or the ingredient containers C 1 , C 2 , and C 3  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 C 1 , C 2 , and C 3  and then be mixed with the ingredients, and the ingredients accommodated in the ingredient accommodation portion or the ingredient containers C 1 , C 2 , and C 3  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 flavoring 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  31   a  of the initial ingredient accommodation portion  31  may be connected to the first main channel  41 , and the outlet  33   b  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  32   a  and the outlet  32   b  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  31   b  of the final ingredient accommodation portion  31  may be connected to the inlet  32   a  of the intermediate ingredient accommodation portion  32  through the first connecting channel  311 , and the outlet  32   b  of the intermediate ingredient accommodation portion  32  may be connected to the inlet  33   a  of the final ingredient accommodation portion  33  through the second connecting channel  312 . In this case, the fluid introduced into the inlet  31   a  of the final ingredient accommodation portion  31  through the first main channel  41  may flow to the first connecting channel  311  through the outlet  31   b  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  32   a  of the intermediate ingredient accommodation portion  32  through the first main channel  311  may flow to the second connecting channel  312  through the outlet  32   b  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  33   a  of the final ingredient accommodation portion  33  through the second main channel  312  may flow to the second connecting channel  42  through the outlet  33   b  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 C 1 , C 2 , and C 3  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 C 1 , C 2 , and C 3 , 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”.

     When the pump  52  is driven, the fluid within the tank  51  may be introduced into the pump  52  through the tank discharge channel  55   a , and the fluid discharged from the pump  52  may be heated in the heater  53  while flowing through the water supply channel  55   b  and then be guided to the first main channel  41 . 
     Hereinafter, the beverage dispenser  6  will be described. 
     The beverage dispenser  6  may be connected to the second main channel  42 . That is, the beverage dispenser  6  may include dispenser  62  that dispenses the beverage and a beverage dispensing channel  61  that connects the dispenser  62  to the second main channel  42 . 
     The beverage dispensing channel  61  may connect the second main channel  42  to the dispenser  62 . The beverage dispensing channel  61  may have one or a first end  61   a  connected between the main check valve  314  and the main valve  40  with respect to the second main channel  42  and the other or a second end connected to the dispenser  62 . 
     A beverage dispensing valve  64  that opens and closes the beverage dispensing channel  61  may be installed in the beverage dispensing channel  61 . The beverage dispensing valve  64  may be opened when the beverage is dispensed to open the beverage dispensing channel  61 . The beverage dispensing valve  64  may be opened when residual fluid is removed to open the beverage dispensing channel  61 . The beverage dispensing valve  64  may be opened when the beverage dispenser is cleaned to open the beverage dispensing channel  61 . 
     A decompression component  60  that prevents a pressure of the beverage passing through the beverage dispensing channel  61  from rapidly increasing may be installed in the beverage dispensing channel  61 . The decompression component  60  may be installed behind the beverage dispensing valve  64  with respect to the dispensing direction of the beverage. 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 C 1 , C 2 , and C 3  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 C 1 , C 2 , and C 3  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  55   b  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  55   b  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  150   a  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  157   a , to which the exhaust channel  157  may be connected, and a second channel between a connection portion  154   a , 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  157   a  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  91   a  connected to the fluid supply channel  55   b  and the other or a second end  91   b  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  55   b . The sub channel  91  may be connected to the connection portion  61   a  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  55   b  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  55   a , and the outlet may be connected to the fluid supply channel  55   b.    
     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  55   b.    
     The air removal module  50  may include an air removal channel  50   a  and an air removal valve  50   b  connected to the air removal channel  50   a . The air removal channel  50   a  may be connected to the fluid supply channel  55   b . That is, the air removal channel  50   a  may be branched from the fluid supply channel  55   b.    
     The air removal channel  50   a  may be connected to a point on the fluid supply channel  55   b , which is adjacent to the pump  52 . For example, the air removal channel  50   a  may be connected between the pump  52  and the heater  53  in the fluid supply channel  55   b . In this case, the connection portion between the air removal channel  50   a  and the fluid supply channel  55   b  may be closer to the pump  52  than the heater  52 . 
     The air removal valve  50   b  may include a solenoid valve. When the air removal valve  50   b  is opened, the air removal channel  50   a  may be opened, and air in the air removal channel  50   a  may be discharged to the outside through the air removal valve  50   b . As a result, the air in the pump  52  may flow into the air removal channel  50   a , 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  50   b  in a closed state when the pump  52  operates so that the fluid does not flow through the fluid supply channel  55   b . In a state in which operation of the pump  52  is stopped, the air removal valve  50   b  may be opened. The beverage maker may allow the pump  52  to operate after the air removal valve  50   b  is opened for a predetermined period of time, and the air removal valve  50   a  is closed when the tank  51  is empty to refill the tank  51 .

The base  100  may constitute an outer appearance of a bottom surface of the beverage maker and support the fermentation module  1 , the tank  51 , the heater  53 , and a main frame  130 , which are disposed thereabove. As necessary, components supported by the base  100  may be added, removed, or changed. 
     The beverage maker may further include a residual fluid tray  101  that receives and stores a beverage dropping from the dispenser  62 . The residual fluid tray  101  may be integrated with the base  100  or be coupled to the base  10 . The residual fluid tray  101  may be disposed in front of the base  100 . 
     The fermentation module  1  may have an approximately cylindrical shape. The fermentation module  1  may be supported by the base  100  at a lower side. 
     The fermentation module  1  may be disposed above the base  100 . The fermentation module  1  may be disposed and supported on a fermentation module support portion or support  109  of the base  100 . 
     As described above, the fermentation module  1  may include fermenter module  111  and fermentation lid  107 . Fermentation container  12  (see  FIG.  1   ) may be accommodated in the fermenter module  111 . 
     Fermenter  112  (see  FIG.  1   ) may be accommodated in the fermentation case  160 . The insulation portion may be disposed between the fermenter  112  and the fermentation case  160  to insulate the fermenter  112 . The evaporator  134  (see  FIG.  1   ) and the heater  14  (see  FIG.  1   ) may be disposed between the insulation portion and the fermenter  112 . That is, the insulation portion may surround the evaporator  134  and/or the heater  14  together with the fermenter  112 . Thus, the temperature of the fermenter  112  may be easily controlled. 
     The fermentation lid  107  may be disposed above the fermenter module  111  to open and close the fermenter module  111  at an upper side. Lid seating body  179  may be disposed above the fermentation case  160  to support the fermentation lid  107  at a lower side. 
     The fermentation case  160  may be placed on the fermentation module support  109  of the base  100 .

FIG.  16    is a horizontal cross-sectional view of the heater and the heater case according to an embodiment. 
     As described above, the heater  53  may heat the fluid supplied to the fermentation module  1 . The heater  53  may include a housing  530 , an inner passage S provided in the housing  530  (see  FIG.  16   ), and an inlet  531   a  and outlet  531   b  that communicate with the inner passage S. The heater  53  may further include a heating coil C (see  FIG.  16   ) disposed within the inner passage S. 
     The housing  530  may be made of a metal material. The inner passage S may be disposed inside of the housing  530  and have a ring shape. That is, the inner passage S may be a substantially donut-shaped space. 
     The fluid introduced into the inlet  531   a  may pass through the inner passage S and then be discharged to the outlet  531   b  after being heated by the heating coil C. The inlet  531   a  and the outlet  531   b  may protrude from the housing  530 . A channel (not shown) through which the fluid may flow may be connected to the inlet  531   a  and the outlet  531   b . Each of the channels connected to the inlet  531   a  and the outlet  531   b  may be provided in the fluid supply channel  55   b  (see  FIG.  1   ). 
     The inlet  531   a  and the outlet  531   b  may be spaced apart from each other. The inlet  531   a  may be disposed at one or a first side of the housing  530 . The outlet  531   b  may be disposed at the other or a second side of the housing  530 . The inlet  531   a  and the outlet  531   b  may be disposed in a straight line. 
     The inlet  531   a  may protrude downward from a bottom surface of the housing  530 , and the outlet  531   b  may protrude upward from a top surface of the housing  530 . In this case, the inlet  531   a  and the outlet  531   b  may be disposed in a straight line passing through a middle portion of the heater  53  in the lateral direction. Thus, a distance from the inlet  531   a  to the outlet  531   b  with respect to the flow direction of fluid may be elongated, and the fluid passing through the inner passage S may be sufficiently heated. 
     The heating coil C may heat the fluid flowing inside of the inner passage S. The heating coil C may have a shape wound several times to surround at least one of a front recess  532  (see  FIG.  16   ) or a rear recess  538 , which will be described hereinafter. 
     Protrusion bosses  533  and  534  may be disposed on the heater  53 . The protrusion bosses  533  and  534  may communicate with the inside of the heater  53 , that is, the inner passage S. 
     The protrusion bosses  533  and  534  may protrude forward from the front surface of the housing  530 . The protrusion bosses  533  and  534  may include at least one of a sensor connection boss  533  to which the temperature sensor  57  (see  FIG.  1   ) may be connected and a valve connection boss  534  to which the safety valve  53   a  may be connected. Hereinafter, a case in which both the sensor connection boss  533  and the valve connection boss  534  are disposed on the heater  53  will be described as an example. 
     The temperature sensor  57  may be connected to the sensor connection boss  533  to sense the fluid supply temperature of the heater  53 , that is, the temperature of the fluid heated while passing through the inside of the inner passage S. 
     The sensor connection boss  533  may be adjacent to the outlet  531   b  among the inlet  531   a  and the outlet  531   b . The fluid temperature sensor  57  may sense the fluid temperature immediately before passing through the outlet  531   b.    
     A sensor fixing boss  533   a  to fix the temperature sensor  57  may be further disposed on the heater  53 . The sensor fixing boss  533   a  may protrude from the housing  530  in a direction parallel to the sensor connection boss  533 . The sensor fixing boss  533   a  may not communicate with the inner passage S. 
     The temperature sensor  57  may include a sensor body connected to the sensor connection boss  533  and a sensor bracket on which the sensor body may be mounted and coupled to the sensor fixing boss  533   a . While the sensor body is connected to the sensor fixing boss  533   a , a coupling member, such as a screw, may couple the sensor bracket to the sensor fixing boss  533   a . A screw thread configured to be coupled to the coupling member may be disposed on an inner circumference of the sensor fixing boss  533   a.    
     The safety valve  53   a  may be connected to the valve connection boss  534  to limit a maximum inner pressure of the heater  53 . That is, the safety valve  53   a  may limit the inner pressure of the inner passage S. If the inner pressure of the inner passage S is greater than or equal to a specific pressure, the safety valve  53   a  may be opened. When the safety valve  53   a  is opened, a portion of the fluid in the inner passage may pass through the safety valve to flow along a channel (not shown) connected to the safety valve. The channel may allow the fluid to return between the pump  52  and the heater  53  among the fluid supply channels  55   b  (see  FIG.  1   ). 
     The valve connection boss  534  may be adjacent to the outlet  531   b  of the inlet  531   a  and the outlet  531   b . When the inner pressure of the inner passage S is greater than or equal to a specific pressure, sufficiently heated fluid may be returned to the inlet  531   a  by returning to a previous state of the heater  53 , and efficiency of the heater  53  may be improved. 
     The heater  53  may be provided with the thermostat  58  that constantly adjusts the temperature of the heater  53 . The thermostat  58  may be disposed on an outer surface of the housing  530 , more specifically, on a top surface of the housing  530 . The thermostat  58  may be accommodated in the heater case  113 . 
     The thermostat  58  may be adjacent to the outlet  531   b  among the inlet  531   a  and the outlet  531   b . The thermostat  58  may easily adjust the temperature of the fluid flowing out of the outlet  531   b.

     The fuse bracket  540  may be coupled to a rear surface of the housing  530 . The heater  53  may have a rear recess  538 , in which the fuse bracket  540  may be disposed, and a coupling boss  539  to which the fuse bracket  540  may be coupled in the rear recess  538 . 
     The rear recess  538  may be recessed forward from the rear surface of the housing  530 , and the coupling boss  539  may protrude backward from the rear recess  538 . That is, the coupling boss  539  may protrude in a direction opposite to the protrusion bosses  533  and  534 . 
     The fuse bracket  540  may be coupled to the coupling boss  539  and be disposed within the rear recess  538 . The fuse bracket  540  may protrude backward from the rear surface of the housing  530 . 
     One of the front recess  532  and the rear recess  538  may be referred to as a first recess, and the other may be referred to as a second recess. A recessed depth of the rear recess  538  may be greater than a recessed depth of the front recess  532 . The rear recess  538  and the front recess  532  may contact each other. 
     The inner passage S in the housing  530  may be provided in a donut shape. The heating coil C disposed in the inner passage S may surround at least one of the front recess  532  or the rear recess  538 . For example, the heating coil C may be disposed to surround the rear recess  538  several times, as illustrated in  FIG.  16   . 
     The heater  53  may be accommodated in the heater case  113 . The heater case  113  may minimize heat transfer from the heater  53  to surroundings. As described above, the heater case  113  may support the tank case  149  (see  FIG.  3   ). 
     The heater case  113  may space the heater  53  upward with respect to the base  100 . Thus, heat transfer of the heater  53  to the base  100  may be minimized. Also, the wire may be connected to the terminals  536   a  and  536   b  provided on the bottom surface of the heater  53 , and the channel may be connected to the inlet  531   a.    
     Front openings  113   a  and  113   b  may be defined in the heater case  113 . The front openings  113   a  and  113   b  may be defined by penetrating a portion of a front surface of the heater case  113 .

For example, the first opening  113   a  may be defined above the coupling portion  114  and the second open portion  113   b  may be defined below the coupling portion  114 . 
     The protrusion bosses  533  and  534  of the heater  53  may protrude toward the first opening  113   a  or be disposed in the first opening  113   a . That is, the sensor connection boss  533  and the sensor fixing boss  533   a  may protrude toward the first opening  113   a  or be disposed in the first opening  113   a . Thus, the fluid temperature sensor  57  may be connected to the sensor connection boss  533  through the first opening  113   a  and fixed to the sensor fixing boss  533   a.    
     The valve connection boss  534  may protrude toward the first opening  113   a  or be disposed in the first opening  113   a . The safety valve  53   a  may be connected to the valve connection boss  534  through the first opening  113   a.

A coupling member, such as a screw, may be coupled to the fixing bracket  535  through the coupling hole  114   c . The heater  53  may be firmly fixed to the heater case  113 . 
     According to embodiments, the heater case may accommodate the heater. Thus, heat transfer from the heater to surroundings may be minimized. 
     The heater case may allow the heater to be spaced apart from the base. In addition, heat of the heater may not be transferred to the base, and the wire and the channel may be connected to the bottom surface of the heater case. 
     The heater case may support the tank case. As the number of members for supporting the tank case is reduced, production costs may be reduced, and the beverage maker may be compact. 
     The thermostat accommodated in the heater case may be connected to the heater. Thus, fluid having an appropriate temperature may be supplied to the fermentation module, and the thermostat may be protected. 
     The thermostat may be disposed closer to the outlet of the inlet and outlet of the heater. The thermostat may easily control the temperature of the fluid discharged from the outlet. 
     The protrusion boss that protrudes toward the first opening of the heater case or disposed in the first opening may be disposed on the heater. Thus, the temperature sensor or safety valve may be easily connected to the protrusion boss through the first opening. 
     The opening facing the space between the base and the heater may be defined in the heater case. Thus, the wire or the channel may be connected to the heater from the lower side of the heater. 
     The fixing bracket for fixing the heater to the heater case may be coupled to the coupling portion of the heater case, and the coupling portion may be connected to the opening. Thus, coupling of the fixing bracket and the coupling portion may be facilitated. 
     The protrusion boss may be adjacent to the outlet of the inlet and outlet of the heater. Thus, the fluid supply temperature sensor may detect the fluid temperature just before passing through the outlet. In addition, when the safety valve is opened, sufficiently heated fluid may pass through the safety valve and then be reintroduced into the heater, and efficiency of the heater may be improved. 
     The fuse bracket may be disposed in the recess defined in the heater and be coupled to the coupling boss disposed in the recess. Thus, the fuse bracket may be easily coupled to the heater. 
     The inner passage may have the ring (donut) shape surrounding the recess. Thus, the heater may be compact, and also, the flow path from the inlet to the outlet may be elongated so that the fluid is sufficiently heated. 
     The heating coil may be disposed inside of the inner passage to surround the recess. Thus, the heating coil may efficiently heat the fluid throughout the inner passage. 
     The first recess to which the fixing bracket may be coupled and the second recess to which the fuse bracket may be disposed may contact each other. The inner passage may have the ring (donut) shape. 
     The inlet and outlet of the heater may be disposed in a straight line. Thus, the fluid may flow uniformly and smoothly along the inner passage, and the flow path from the inlet to the outlet may be elongated so that the fluid is sufficiently heated. 
     The heater may be provided with the terminal to which a ground line may be connected. Thus, the user may be prevented from being injured due to electric shock.

     The beverage maker may further include an ingredient supplier configured to supply an ingredient to the fermentation module. The heater case may be spaced downward from the ingredient supplier. 
     The details of one or more embodiments are set forth in the accompanying drawings and the description. Other features will be apparent from the description and drawings, and from the claims. 
     The disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments, which fall within the true spirit and scope. Thus, embodiments are to be considered illustrative, and not restrictive, and the technical spirit is not limited to the embodiments. Therefore, the scope is defined not by the detailed description but by the appended claims, and all differences within the scope will be construed as being included. 
     It will be understood that when an element or layer is referred to as being “on” another element or layer, the element or layer can be directly on another element or layer or intervening elements or layers. In contrast, when an element is referred to as being “directly on” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     It will be understood that, although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section could be termed a second element, component, region, layer or section without departing from the teachings of the present invention. 
     Spatially relative terms, such as “lower”, “upper” and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “lower” relative to other elements or features would then be oriented “upper” relative to the other elements or features. Thus, the exemplary term “lower” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     Embodiments of the disclosure are described herein with reference to cross-section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of the disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the disclosure should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
     Any reference in this specification to “one embodiment,” “an embodiment,” “example embodiment,” etc., means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with any embodiment, it is submitted that it is within the purview of one skilled in the art to effect such feature, structure, or characteristic in connection with other ones of the embodiments. 
     Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
