Description

Beverage Maker {BAVERAGE MAKER}

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

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

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

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

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

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

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

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

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

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

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

Hereinafter, the material feeder 3 will be described in detail.

In the case of manufacturing beer using a beverage maker, materials for manufacturing beer may include water, malt, yeast, hops, flavor additives, and the like.

The beverage maker may include both the ingredient feeder 3 and the fermentation container 12, and ingredients for preparing the beverage may be distributed and accommodated in the ingredient feeder 3 and the fermentation container 12. Fermentation container 12 may contain some of the ingredients for beverage preparation, and the material feeder 3 may contain the rest of the ingredients. The remaining ingredients contained in the material feeder 3 may be supplied to the fermentation container 12 together with water supplied from the water supply module 5, and may be mixed with some of the materials contained in the fermentation container 12.

The fermentation container 12 may contain main ingredients essential for beverage production, and the material feeder 3 may contain additives added to the main ingredients. In this case, the additives contained in the material feeder 3 may be mixed with water supplied from the water supply module 5 and supplied to the fermentation container 12, and mixed with the main material contained in the fermentation container 12.

The main material accommodated in the fermentation container 12 may be a material having a higher capacity than other materials. For example, in the case of beer production, the main material may be malt among malt, yeast, hops and flavor additives. In addition, the additives accommodated in the material feeder 3 may be materials other than malt among materials for manufacturing beer, and may include yeast, hops, flavor additives, and the like.

The beverage maker may include the fermentation container 12 without including the material feeder 3, in which case the main material may be accommodated in the fermentation container 12, and the user may enter the fermentation container 12. Additives may be added directly.

When the beverage maker includes both the material feeder 3 and the fermentation container 12, it is possible to more conveniently prepare the beverage. Hereinafter, for convenience, both the material feeder 3 and the fermentation container 12 are included. An example will be described. However, it goes without saying that the present invention is not limited to including both the material feeder 3 and the fermentation container 12 .

Materials in the fermentation container 12 may be fermented over time, and beverages prepared in the fermentation container 12 may flow to the second main channel 42 through the main channel connection 115, and may flow from the second main channel 42 to the beverage dispenser 6 and be dispensed.

Ingredient feeder 3 may contain ingredients necessary for preparing a beverage, and may be configured to allow water supplied from the water supply module 5 to pass through. For example, when the beverage produced in the beverage maker is beer, the material accommodated in the material feeder 3 may be yeast, hops, flavor additives, and the like.

The material accommodated in the material feeder 3 may be directly accommodated in the material containing portions 31, 32, and 33 formed in the material feeder 3. At least one material accommodating part 31, 32, 33 may be formed in the material feeder 3. A plurality of material accommodating portions 31, 32, and 33 may be formed in the material supply unit 3, and in this case, the plurality of material accommodating portions 31, 32, and 33 may be formed separately from each other.

Inlets 31A, 32A, and 33A through which fluid flows in and outlets 31B, 32B, and 33B through which fluid flows out may be formed in each of the material accommodating portions 31, 32, and 33. The fluid introduced into the inlet of one material accommodating unit may be mixed with the material of the material accommodating unit and flowed out through the outlet.

On the other hand, the material accommodated in the material feeder 3 can be accommodated in the capsules C1, C2, and C3. In this case, the capsules C1, C2, and C3 may be accommodated in the material accommodating parts 31, 32, and 33, and the material accommodating parts 31, 32, and 33 may be referred to as capsule mounting parts.

When materials are accommodated in the capsules C1, C2, and C3, the material feeder 3 may be configured to allow the capsules C1, C2, and C3 to be seated and withdrawn, and the material feeder 3 may be configured as a capsule kit assembly in which the capsules C1, C2, and C3 are detachably accommodated.

For example, a first additive, a second additive, and a third additive may be accommodated in the material supplier 3 . The first additive may be yeast, the second additive may be hops, and the third additive may be a flavor additive. The material feeder 3 may include a first capsule mounting portion 31 in which the first capsule C1 containing the first additive is accommodated, a second capsule mounting portion 32 in which the second capsule C2 containing the second additive is accommodated, and a third capsule mounting portion 33 in which the third capsule C3 containing the third additive is accommodated.

The material contained in the material container or the capsules C1, C2, and C3 may be extracted by the hydraulic pressure of the water supplied from the water supply module 5.

When the material is extracted by water pressure, water supplied from the water supply module 5 to the first main channel 41 may be mixed with the material while passing through the material accommodating part or the capsules C1, C2, and C3, and the material contained in the material accommodating part or the capsules C1, C2, and C3 may flow into the second main channel 42 together with the water.

In the material feeder 3, a plurality of additives of different types may be accommodated separately from each other. For example, when preparing beer, a plurality of additives accommodated in the material feeder 3 may be yeast, hops, and flavor additives, which may be accommodated separately from each other.

When a plurality of material accommodating portions are formed in the material feeder 3, the plurality of material accommodating portions 31, 32, and 33 may be connected in series with respect to the flow direction of water.

In more detail, the material supplier 3 connects the outlet of any one of the plurality of material accommodating parts 31, 32, and 33 to the inlet of the other material accommodating part. It may include at least one connection channel 311, 312.

In addition, the plurality of material accommodating units 31, 32, and 33 may include an initial material accommodating unit 31 and a final material accommodating unit 33. The plurality of material accommodating parts 31, 32, and 33 may further include an intermediate material accommodating part 32.

The inlet 31A of the first material accommodating part 31 may be connected to the first main channel 41, and the outlet 33B of the final material accommodating part 33 may be connected to the second main channel 42.

The intermediate material accommodating part 32 may be located between the first material accommodating part 31 and the second material accommodating part 33 with respect to the flow of fluid. The intermediate material accommodating portion 32 may be connected to different connection channels 311 and 312 at the inlet 32A and the outlet 32B, respectively.

As shown in FIG. 1, when three material accommodation units are formed in the material supply unit 3, the outlet 31B of the first material accommodation unit 31 may be connected to the inlet 32A of the intermediate material accommodation unit 32 and the first connection channel 311, and the outlet 32B of the intermediate material accommodation unit 32 may be connected to the inlet 33A of the final material accommodation unit 33 and the second connection channel 312.

In this case, the water introduced into the inlet 31A of the first material accommodating portion 31 through the first main channel 41, along with the first additive accommodated in the initial material accommodating portion 31, may flow into the first connection channel 311 through the outlet 31B.

The fluid (mixture of water and the first additive) introduced into the inlet 32A of the intermediate material accommodating portion 32 through the first connection channel 311, along with the second additive accommodated in the intermediate material accommodating portion 32 It may flow into the second connection channel 312 through the outlet 32B.

The fluid (a mixture of water, the first additive and the second additive) introduced into the inlet 33A of the final material accommodating portion 33 through the second connection channel 312 may flow to the second main channel 42 through the outlet 33B together with the third additive accommodated in the final material accommodating portion 33.

The fluid (a mixture of water, the first additive, the second additive, and the third additive) flowing out through the second main channel 42 is guided to the main channel connection part 115 of the fermentation module 1, and the fermentation container 12. It can be introduced into the interior.

However, the configuration of the material supplier 3 is not limited thereto, and for example, when there is no intermediate material accommodation unit, the material supplier 3 may be formed with two material accommodation units. In this case, one material accommodating part may be an initial material accommodating part, and the other material accommodating part may be a final material accommodating part. An outlet of the first material accommodating unit and an inlet of the final material accommodating unit may be connected by a connection channel.

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

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

When the material accommodated in the material feeder 3 is accommodated in the capsules C1, C2, and C3, the first material accommodating portion 31 may be referred to as an initial capsule loading portion, the intermediate material accommodating portion 32 may be referred to as an intermediate capsule loading portion, and the final material containing portion 33 may be referred to as a final capsule loading portion.

Hereinafter, the gas discharger 7 will be described in detail.

The gas discharger 7 is connected to the fermentation module 1 and can discharge gas generated inside the fermentation container 12 .

In more detail, 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 after the gas pressure sensor 72 in the gas discharge direction.

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

Gas in the fermentation container 12 may flow to the gas discharge channel 71 and the gas pressure sensor 72 through the gas discharge channel connection part 121 . The gas pressure sensor 72 may detect a pressure of gas flowing from the fermentation container 12 through the gas discharge channel connection 121 to the gas discharge channel 71 .

The gas discharge valve 73 may be turned on and opened when air is injected into the fermentation container 12 by the air injector 8. The beverage maker may inject air into the fermentation container 12 to evenly mix malt and water, and at this time, air bubbles generated in the liquid malt may be discharged to the outside through the gas discharge channel 71 and the gas discharge valve 73 at the top of the fermentation container 12.

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

By means of the noise reducer 77, even if the pressure relief valve 76 is opened, the internal pressure of the fermentation container 12 can be gradually lowered compared to the gas discharge valve 73.

The pressure release valve 76 may be opened to release the pressure in a state in which the internal pressure of the fermentation container 12 is increased due to gas generation as fermentation of the beverage proceeds. The noise reduction device 77 can effectively reduce noise generated due to a pressure difference between the inside and outside of the fermentation container 12 .

The pressure release valve 76 may be controlled to open/close in a secondary fermentation step (S800) to be described later.

The air injector 8 will be described below.

The air injector 8 may be connected to the water supply channel 55B or the first main channel 41 to inject air. Hereinafter, for convenience of description, a case in which the air injector 8 is connected to the water supply channel 55B will be described.

The air injector 8 may be connected to the opposite side of the sub-channel 91 to be described later with respect to the water supply heater 53.

In this case, the air injected from the air injector 8 may pass through the water heater 53 and flow into the sub channel 91 together with the remaining water inside the water heater 53 . As a result, residual water in the feed water heater 53 is removed and the feed water heater 53 can be kept clean.

Alternatively, the air injected from the air injector 8 into the first main channel 41 may pass through the bypass channel 43 and the second main channel 42 in sequence and be injected into the fermentation container 12 . This allows stirring or aeration to be performed within the fermentation container 12 .

Alternatively, the air injected from the air injector 8 into the first main channel 41 may be guided to the material supplier 3 and flow to the capsule mounting parts 31, 32, and 33. Residual water or debris in the capsules C1, C2, and C3 or the capsule mounting parts 31, 32, and 33 may flow into the second main channel 42 by the air injected by the air injector 8. The capsules C1, C2, and C3 and the capsule mounting parts 31, 32, and 33 can be kept clean by the air injected by the air injector 8.

The air injector 8 may include an air injection channel 81 connected to the water supply channel 55B or the first main channel 41 and an air pump 82 connected to the air injection channel 81 . The air pump 82 may pump air into the air injection channel 81 .

An air injection check valve 83 that prevents water flowing into the water supply channel 55B by the water supply pump 52 from flowing into the air pump 82 through the air injection channel 81 may be installed in the air injection channel 81.

The air injector 8 may further include an air filter 82A. The air filter 82A may be provided in the suction part of the air pump 82, and external air may pass through the air filter 82A and be sucked into the air pump 82. Thus, the air pump 82 may inject clean air into the air injection channel 81 .

Hereinafter, the air regulator 15 will be described in detail.

The air regulator 15 can regulate the pressure between the inner wall of the fermenter 112 and the outer surface of the fermentation container 12 .

The air regulator 15 may supply air between the fermentation container 12 and the inner wall of the fermentation tank 112 or, conversely, exhaust air between the fermentation container 12 and the inner wall of the fermentation tank 112 to the outside.

The air regulator 15 may include an air supply channel 154 connected to the fermentation module 1 and an exhaust channel 157 connected to the air supply channel 154 to exhaust air to the outside.

One end 154A of the air supply channel 154 may be connected to the first main channel 41, and the other end may be connected to the fermentation module.

The air supply channel 154 may be connected to the fermentation module 1, in particular, the fermentation lid 107. An air supply channel connection unit 117 to which the air supply channel 154 is connected may be provided in the fermentation module 1, and the air supply channel connection unit 117 may communicate with the inner wall of the fermentation tank 112 and the outer surface of the fermentation container 12.

Air injected from the air injector 8 into the first main channel 41 may be guided between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 through the air supply channel 154 .

The air injector 8 may function as an air supplier supplying air between the fermentation container 12 and the fermentation tank 112 together with the air supply channel 154 .

The air supplied into the fermentation tank 112 may pressurize the fermentation container 12 between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 .

The beverage in the fermentation container 12 can be pressurized by the fermentation container 12 pressed by air, and when the main valve 40 and the beverage take-out valve 64 are opened, the main channel connection portion 115 passes through and flows into the second main channel 42. The beverage flowing from the fermentation container 12 to the second main channel 42 may be taken out through the beverage dispenser 6 .

The air pump 82 may supply air such that a predetermined pressure is formed between the fermentation container 12 and the fermentation tank 112, and between the fermentation container 12 and the fermentation tank 112, the fermentation container 12. A pressure that facilitates taking out the beverage may be formed.

The air pump 82 maintains an off state while beverage dispensing is in progress, and when the beverage dispensing is finished, the air pump 82 may be driven for the next beverage dispensing and then stopped.

Thereby, when the beverage preparation is completed, the beverage maker does not take the fermentation container 12 out of the fermentation module 1, and the beverage in the fermentation container 12 is placed inside the fermentation module 1. The beverage can be taken out through the beverage take-out channel module 6.

A configuration in which the air regulator 15 includes the air injector 8 and a separate air supply pump is also possible. In this case, the air supply channel 154 may be connected to the air supply pump without being connected to the first main channel 41 . However, the air pump 82 is configured to simultaneously inject air into the fermentation container 12 and supply air between the fermentation container 12 and the fermentation tank 112 to compact the product and reduce costs. It will be more preferable in terms of reduction.

On the other hand, the exhaust channel 157, along with a portion of the air supply channel 154, may function as an air exhaust passage for exhausting air between the fermentation container 12 and the fermentation tank 112 to the outside.

The exhaust channel 157 may be located outside the fermentation module 1. The exhaust channel 157 may be connected to a portion of the air supply channel 154 located outside the fermenter 112.

The air supply channel 154 may include a first channel from the connection part 154A connected to the first main channel 41 to the connection part 157A to which the exhaust channel 157 is connected, and a second channel from the connection part 154A to which the exhaust channel 157 is connected to the air supply channel connection part 117. The first channel may be an air supply channel that guides the air pumped by the air pump 82 to the second channel. In addition, the second channel supplies air that has passed through the air supply channel between the fermentation tank 112 and the fermentation container 12, or air flowing out between the fermentation tank 112 and the fermentation container 12 to the connection channel 157. It may be a combined air supply and exhaust channel for guiding.

An exhaust valve 156 opening and closing the exhaust channel 157 may be connected to the exhaust channel 157 .

The exhaust valve 156 may be opened to exhaust air between the fermentation container 12 and the fermentation tank 112 to the outside when the fermentation container 12 is inflated during beverage preparation. The exhaust valve 156 may be controlled to open when water is supplied by the water supply channel module 5 . When air is injected by the air injection channel module 8, the exhaust valve 156 can be controlled to open.

The exhaust valve 156 may be opened to bleed air between the fermentation container 12 and the fermentation vessel 112 when beverage extraction from the fermentation container 12 is completed. After the beverage is taken out, the user may take the fermentation container 12 out of the fermentation tank 112, because safety accidents may occur when the inside of the fermentation tank 112 maintains a high pressure. The exhaust valve 156 may be controlled to open when beverage dispensing from the fermentation container 12 is completed.

The air controller 15 may further include an air supply valve 159 that regulates air pumped by the air pump 82 and supplied between the fermentation container 12 and the fermentation tank 112 .

The air supply valve 159 may be installed in the air supply channel 154. In more detail, the air supply valve 159 may be installed between a connection part 154A of the air supply channels 154 with the first main channel 41 and a connection part 157A with the exhaust channel 157.

The sub-channel 91 may be connected between the feed water pump 52 and the feed water heater 53 for the feed water channel 55B.

In addition, the sub-channel 91 may be connected to the beverage dispensing channel 61 between the connection portion 61A of the second main channel 42 and the beverage dispensing valve 64 .

Water supplied by the water supply pump 52 or air pumped by the air pump 82 may be guided to the beverage dispensing channel 61 through the sub channel 91, and may be dispensed into the dispenser 62, and residual water or beverage remaining inside the beverage dispenser 6 may be removed.

A sub-valve 92 opening and closing the sub-channel 91 may be installed in the sub-channel 91 .

The sub valve 92 may open the sub channel 91 when dispensing beverages or cleaning the inside.

In addition, a sub check valve 93 may be installed in the sub channel 91 to prevent the beverage in the beverage dispensing channel 61 from flowing backward to the water supply module 5 . The sub check valve 93 may be located 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 water removal channel of the water supply module 5 . For example, when the air pump 82 is turned on while the air supply valve 159, the bypass valve 35, and the material supply valve 310 are closed and the sub valve 92 is open, the air injected into the air injection channel 81 passes through the water supply heater 53 and flows into the sub channel 91, passes through the sub valve 92, flows into the beverage dispensing channel 61, and then is discharged through the dispenser 62. there is In this process, the air is discharged to the dispenser 62 together with the remaining water remaining in the water supply module 5, more specifically, the water supply heater 53 and the water supply channel 55B, so that the remaining water can be removed.

Also, the sub-channel 91 may function as a cleaning channel. This will be described in detail in the cleaning step (S100) (S1100) and the dispenser cleaning process of the beverage dispensing step (S1000), which will be described later.

The water flowing into the bypass channel 43 may flow into the second main channel 43 through the bypass valve 35, flow into the beverage dispensing channel 62, pass through the beverage dispensing valve 64, and then be dispensed from the dispenser 62.

During the above control, the main channels 41 and 42, the bypass channel 43, the sub channel 91, the beverage dispensing channel 64, the valves installed in the respective channels, and the dispenser 62 can be sterilized and washed. In addition, each capsule mounting portion 31, 32, 33 and the connection channel 311, 312 can be sterilized and washed.

The beverage maker may perform the cleaning as described above during the cleaning set time, and may complete the cleaning process after the cleaning set time.

The controller 281A may turn off the water supply pump 52 and the water supply heater 53 after the cleaning set time has elapsed, and may close the beverage dispensing valve 64, the bypass valve 35, the material supply valve 310 and the sub valve 92.

And, the beverage maker of this embodiment may include a beverage production step of producing a beverage.

For the beverage manufacturing step, the user may open the fermentation lid 107 and insert the fermentation container 12 into the opening 170 to be seated in the fermentor module 111 . At this time, malt may be accommodated inside the fermentation container 12 . The malt may be accommodated in the form of malt.

Then, the user can close the fermentation lid 107, and the fermentation container 12 can be accommodated in the fermenter module 111 and the fermentation lid 107. At this time, the inside of the fermentation tank 112 may be closed by the fermentation lid 107.

In addition, the user inserts a plurality of capsules C1, C2, and C3 into the material feeder 3 before and after the fermentation container 12 is seated, and then the plurality of capsule mounting portions 31, 32, and 33 are covered with the lead module 37.

The user may input a beverage preparation command through an input unit connected to the controller 281A, a remote control, or a mobile terminal. The controller 281A may control the beverage maker to a beverage preparation step according to an input of a beverage preparation command.

The beverage preparation step may include a water supply step (S200).

The water supply step (S200) may be a liquid malt forming step of forming liquid malt by evenly mixing (Mixing) the malt in the fermentation container 12 with hot water.

The controller 281A may turn on the water supply pump 52 and the water supply heater 53 during the water supply step (S200), and may keep the material supply valve 310 closed. The controller 281A may open the bypass valve 35 and the main valve 40 during the water supply step (S200).

Meanwhile, the controller 281A may open the exhaust valve 156 when water is supplied to the fermentation container 12 .

During the above control, the water discharged from the water tank 51 may pass through the feed water pump 52, flow to the feed water heater 53, and be heated by the feed water heater 53. Water heated by the feedwater heater 53 may flow from the first main channel 41 to the bypass channel 43 and pass through the bypass valve 35 to flow to the second main channel 42 . Water flowing through the second main channel 42 may pass through the main valve 40 and be introduced into the fermentation container 12 . The hot water introduced into the fermentation container 12 may be mixed with the malt contained in the fermentation container 12, and the malt in the fermentation container 12 may be mixed with water and gradually diluted. Since hot water is supplied to the fermentation container 12, the malt contained in the fermentation container 12 can be quickly and evenly mixed with the hot water.

The fermentation container 12 can be gradually expanded when the water is introduced as described above, and a part of the air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 is inflated as the fermentation container 12 is expanded. It may flow into the air supply channel 154 and be discharged through the exhaust valve 156.

Thus, while water is introduced into the fermentation container 12, the fermentation container 12 can be supplied with water without bursting or tearing inside the fermentation tank 112.

On the other hand, in the water supply step (S200), it is preferable that the water supply heater 53 heats the water to 50 ° C to 70 ° C, and the controller 281A may control the water supply heater 53 according to the temperature detected by the water supply temperature sensor 57.

The controller 281A may perform the water supplying step (S200) until the accumulated water quantity detected by the flow meter 56 reaches the set flow rate, and when the accumulated water quantity detected by the flow meter 56 reaches the set flow rate, the water supplying step (S200) may be completed.

Upon completion of the water supplying step (S200), the controller 281A may turn off the water supply pump 52 and the water supply heater 53, and may close the bypass valve 35. The controller 281A may close the gas discharge valve 73 and the exhaust valve 156 when the water supply step (S200) is completed.

Meanwhile, the controller 281A may control air to be introduced into the fermentation container 12 during the water supply step (S200).

The controller 281A firstly introduces water into the fermentation container 12 and then stops it, then injects air into the fermentation container 12 and then stops it, and finally, it is possible to secondarily introduce hot water into the fermentation container 12 and then stop it. It is also possible to complete the water supply step (S200) after sequentially completing all of these primary water introduction, air injection, and secondary water introduction.

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

In another example of the water supply step (S200), it is possible to sequentially perform a first hot water supply process of first supplying hot water, an air injection process of injecting air, and a second hot water supply process of secondly injecting hot water.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Even during the air supply step (S400), the refrigerating cycle device 13 and the heater 14 may be turned on and off according to the temperature detected by the temperature sensor 16, and the refrigerating cycle device 13 and the heater 14 may be controlled on and off until the additive input step (S500) described later is completed.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

When the remaining water removal step (S600) of the material feeder is completed, the controller 281A may display a capsule separation message on the display 282 indicating that the capsules C1, C2, and C3 may be removed, and the user may remove the empty capsule from the material feeder 3.

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

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

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

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

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

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

During the fermentation process, the controller 281A controls the refrigerating cycle device 13 and the heater 14 so that the temperature measured by the temperature sensor 16 maintains the fermentation target temperature (eg, 21° C.). At this time, the fermentation target temperature may be higher than the previous fermentation target temperature.

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

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

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

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

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

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

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

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

During the aging step, the controller 281A may stand by for the aging time, and during this aging time, the temperature of the beverage is maintained between the upper limit of the set aging temperature and the lower limit of the set aging temperature. The refrigeration cycle device 13 and the heater 14 can be controlled.

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

Exceptionally, when the temperature outside the beverage maker is lower than the lower limit of the set aging temperature, the controller 281A may turn on the heater 14 if the temperature detected by the temperature sensor 16 is less than the lower limit, and may turn off the heater 14 if the temperature detected by the temperature sensor 16 is greater than or equal to the upper limit of the set aging temperature.

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

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

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

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

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

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

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

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

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

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

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

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

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

A user may take out a beverage at least once through the dispenser 62 . That is, the beverage dispensing process may be performed at least once, and the controller 281A may determine whether the beverage dispensing is completed using information such as the time when the dispenser 62 is open, the time the air pump 152 is driven, and the time when the main valve 40 is turned on after beverage production is completed.

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

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

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

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

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

On the other hand, before the user opens the fermentation lid 107, if some of the air between the fermentation container 12 and the fermentation vessel 112 is exhausted through the exhaust valve 156, the fermentation lid 107 is opened. When the fermentation container 12 does not bounce upward, it is maintained inside the fermentation vessel 112.

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

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

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

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

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

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

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

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

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

When the water supply pump 52 is turned on, the water sucked into the water supply pump 52 from the water tank 51 may flow from the water supply channel 55B to the sub channel 91, pass through the sub valve 92, flow to the beverage dispensing channel 61, pass through the beverage dispensing valve 64, and be discharged to the dispenser 62. In the process of dispensing the water into the dispenser 62, the water may be removed together with the dregs and foreign substances inside the dispenser 62 to perform cleaning.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The water flowing through the material feeder 3 passes through the material supply valve 310, the first capsule mounting unit 31, the middle capsule mounting unit 32, and the final capsule mounting unit 33 in sequence, flows into the second main channel 43, passes through the main valve 40, and flows into the cleaning pack accommodated in the fermenter 112.

The water flowing into the bypass channel 43 may flow into the second main channel 43 through the bypass valve 35, and pass through the main valve 40 to the cleaning pack accommodated in the fermenter 112. It may flow into the pack.

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

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

After the second cleaning set time elapses, the controller 281A may turn off the feed water pump 52 and the feed water heater 53, and may close the main valve 40, the bypass valve 35, the material supply valve 310, the sub valve 92, the gas discharge valve 73, and the exhaust valve 156.

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

5 is a perspective view of the material feeder in a closed state, and FIG. 6 is a perspective view of the material feeder in an open state.

The capsules C1, C2, and C3 described above are exemplary, and hereinafter, material containers C1, C2, and C3 will be named and described instead of capsules. In addition, the material accommodating portion will be described by naming the container mounting portions 31, 32, and 33.

The material supplier 3 may include a material accommodating body 36 having container mounting portions 31, 32, and 33 on which the material containers C1, C2, and C3 containing beverage materials are detachably mounted, and a lid module 37 covering the container mounting portions 31, 32, and 33.

Since a material container can be accommodated in the material feeder 3, the material accommodating body 36 can also be defined as a material container accommodating body.

The lid module 37 may include a lid 38 covering the material receiving body 36 and a locking manipulation unit 371 releasing the locking of the lid 38 . The lid 38 may be rotatably connected to the material receiving body 36 or may be slidably disposed. The lid 38 may be hinged to the material receiving body 36 .

The lead 38 may be composed of a combination of a plurality of members. For example, the lead 38 may include a lower lead 39 and an upper lead 40 . At least one of the lower lead 39 and the upper lead 40 may be connected to the material receiving body 36 .

When the user manipulates the locking manipulation unit 371, locking of the lid 38 may be released. As the locking is released, the lead 38 hinged with the material receiving body 36 may rotate upward of the material receiving body 36 . As the lid rotates upward, the container mounting portions 31, 32, and 33 provided in the material receiving body 36 may be opened to the outside.

In the material receiving body 36 of the material supply unit 3, container mounting portions 31, 32, and 33 in which the beverage material-accommodated material containers C1, C2, and C3 are detachably accommodated may be formed. The number of container mounting parts 31, 32, and 33 is not limited, and at least one may be provided.

The plurality of container mounting parts 31, 32, and 33 may be arranged in a line on the material receiving body 36. The plurality of container mounting parts 31, 32, and 33 may be formed to be spaced apart from the material receiving body 36 in a front-back direction or a left-right direction. The beverage maker is preferably configured to be slim in the left and right directions, the material feeder 3 may be formed long in the front and rear directions, and the plurality of container mounting parts 31, 32, and 33 may be formed to be spaced apart in the front and rear directions on the material receiving body 36.

The lid module 37 may include lockers 372A and 372B for locking the lid 38 . In addition, a support groove 361 for supporting the lockers 372A and 372B and a locking groove 362 for holding the lockers 372A and 372B may be formed in the material receiving body 36 .

The lockers 372A and 372B may be movably provided on the lid module 37 . The lockers 372A and 372B may include at least one locking part 376, and the locking part 376 may be supported by the support groove 361 and caught in the locking groove 362.

The support groove 361 and the locking groove 362 communicate with each other, and the locking part 376 can move from the support groove 361 to the locking groove 362 . The support groove 361 and the locking groove 362 may be formed stepwise from each other.

Based on the upper surface of the material receiving body 36, the support groove 361 may be formed at a higher position than the locking groove 362. Accordingly, when the locking part 376 moves from the support groove 361 to the locking groove 362, the lead module 37 can move downward.

More specifically, when the lid module 37 is closed but unlocked, the lockers 372A and 372B may be supported by the support groove 361 . In this state, when the user rotates the locking manipulation unit 371 in one direction (eg, clockwise), the lead module 37 is locked and can move downward.

When the lid module 37 is closed and in a locked state, the lockers 372A and 372B may be hooked into the locking groove 362 and fixed. Accordingly, the container mounts 31, 32, and 33 may not be opened because the lid 38 rotates arbitrarily. In this state, when the user rotates the locking manipulation unit 371 in the opposite direction (eg, counterclockwise), the lead module 37 is unlocked and can move upward. This will be described in detail later.

FIG. 7 shows the first container mounting unit 31, and it is apparent that those skilled in the art can easily grasp the configuration of the intermediate container mounting unit 32 and the final container mounting unit 33 therefrom.

Hereinafter, a case in which three container mounting portions 31, 32, and 33 are formed in the material feeder 3 will be described as an example.

The container mounting parts 31, 32, and 33 may form an accommodation space S3 defined by the bottom surface 316 and the inner circumferential surfaces 319A and 319B, respectively. Beverage ingredients or ingredient containers (C1) (C2) (C3) can be accommodated in each accommodating space (S3).

The initial container mounting part 31 may be connected to the first main channel 41 through the inlet 31A and connected to the first connection channel 311 through the outlet 31B. The intermediate container mounting portion 32 may be connected to the first connection channel 311 through the inlet 32A and connected to the second connection channel 312 through the outlet 32B. The final container mounting part 33 may be connected to the second connection channel 312 through the inlet 33A and connected to the second main channel 42 through the outlet 33B.

The inlet 31A, 32A, 33A and the outlet 31B, 32B, 33B may protrude from the bottom surface 315 of the container mounting portion 31, 32, 33 to the opposite direction of the accommodation space S3.

The material feeder 3 supplies the fluid to the accommodation space S3 in the container mounting parts 31, 32, 33 through the inlets 31A, 32A, and 33A, or to the accommodation space S3. It may be configured to supply fluid into the material containers C1, C2, and C3 mounted in the space S3.

The container mounting portions 31, 32, and 33 are connected to the inlets 31A, 32A, and 33A to supply fluid into the accommodation space S3 or the material container C1. It may include a fluid supply portion 41.

The fluid supply unit 41 may protrude from one surface (eg, the bottom surface 316) of the container mounting units 31, 32, and 33 into the accommodation space S3. In this case, when the material containers C1, C2, and C3 are accommodated in the accommodation space S3 and the lid module 37 covers the container mounting parts 31, 32, and 33, the fluid supply part 41 can perforate the material container cover CC of the material containers C1, C2, and C3, and a part of the fluid supply part 41 enters the inside of the material container C1, C2, and C3. can

That is, when the lid module 37 covers the container mounting portion 31, the fluid supply unit 41 has a height at which at least a portion of the fluid supply unit 41 is located inside the material containers C1, C2, and C3.

A discharge hole 316A communicating with the outlets 31B, 32B, and 33B may be formed on one surface (eg, bottom surface 316) of the container mounting parts 31, 32, and 33.

At least one perforation part 313A or 313B may be further formed on the one surface (eg, the bottom surface 316) of the container mounting part 31. The perforations 313A and 313B are formed to be adjacent to the discharge holes 316A, so that the material extracted through the holes formed by the perforations 313A and 313B can be easily moved to the discharge holes 316A.

The perforations 313A and 313B may include a first perforation part 313A and a second perforation part 313B positioned on the opposite side of the first perforation part 313A with respect to the discharge hole 316A. The first perforation part 313A and the second perforation part 313B may be spaced apart from each other. That is, the discharge hole 316A may be located between the first perforation part 313A and the second perforation part 313B. As a result, the material contained in the material containers C1, C2, and C3 can be extracted without any residue and moved to the discharge hole 316A more easily.

The fluid supply part 41, the perforation parts 313A and 313B, and the discharge hole 316A may be disposed at positions eccentric from the center of the container mounting parts 31, 32, and 33. In addition, the fluid supply part 41, the perforation part 313A, 313B, and the discharge hole 316A may be spaced apart from each other. As a result, the contact time between the fluid and the material may increase, and the amount of the material mixed with the fluid may increase, and as a result, the amount of the material extracted may also increase.

In addition, as the fluid supply part 41 and the perforation parts 313A and 313B are formed on the same surface (eg, the bottom surface 316) of the container mounting part 31, the flow path between the fluid supply part 41 and the perforation part 313A and 313B can be simpler. In this case, the resistance of the passage is lowered so that the material in the container mount 31 can be extracted more easily.

An inner supply channel 41A (see FIG. 8 ) may be formed in the fluid supply unit 41 . The inner supply channel 41A may include an inner passage 412 formed inside the fluid supply unit 41 and at least one hole 411 supplying the fluid of the inner passage 412 to the accommodation space S3. The inner supply channel 41A may communicate with the inlets 31A, 32A, and 33A. The fluid passing through the inlets 31A, 32A, and 33A may be guided into the accommodation space S3 or the material containers C1, C2, and C3 through the inner supply channel 41A of the fluid supply unit 41.

At least one hole 411 may be formed closer to the upper end than the lower end of the fluid supply unit 41 (or the bottom surface 316 of the container mounting unit 31). Preferably, the hole 411 may be formed at the top of the fluid supply unit 41 .

At least one hole 411 may be formed at a height located inside the material containers C1, C2, and C3 when the material containers C1, C2, and C3 are accommodated in the container mounting portions 31, 32, and 33. Accordingly, the fluid may be guided into the material containers C1, C2, and C3 through the at least one hole 411.

On the other hand, as described above, the container mounting portions 31, 32, and 33 may include perforations 313A and 313B forming a hole in the material container cover CC of the material containers C1, C2, and C3. The perforated portions 313A and 313B may be installed to protrude from the bottom surface 316 of the container mounting portion 31 into the accommodation space S3. The material containers C1, (C2, and C3) are inserted into the container mounting portions 31, 32, and 33 at the upper positions of the container mounting portions 31, 32, and 33 (or the container mounting portion 31). It can be seated on the upper side).

The material container cover CC of the material containers C1, C2, and C3 may be perforated by the fluid supply unit 41, and as a result, the inner supply channel 41A of the fluid supply unit 41 may flow into the material containers C1, C2, and C3.

In addition, the material container cover CC of the material containers C1, C2, and C3 may be cut by the perforations 313A and 313B of the container mounting parts 31, 32, and 33, and as a result, perforations through which material flows may be formed in the material container cover CC of the material containers C1, C2, and C3.

The material accommodated in the material containers C1, C2, and C3 may be extracted through a gap between the perforations 313A and 313B and the perforations or may be extracted through a gap between the fluid supply part 41 and the perforations. In particular, the perforations 313A and 313B may have a shape for widening the area of the gap.

The material extracted from the material containers C1, C2, and C3 may flow into the second main channel 42 through the discharge holes 316A formed in the container mounting portions 31, 32, and 33 and the outlets 31B, 32B, and 33B communicating with the discharge holes 316A.

In order to smoothly move the material extracted through the gap between the fluid supply unit 41 and the perforation to the discharge hole 316A, the bottom surfaces 316 of the container mounting parts 31, 32, and 33 may be inclined at a predetermined angle with respect to the horizontal direction. In particular, the bottom surface 316 is inclined so as to be lowered from the fluid supply unit 41 to the discharge hole 316A, so that the material extracted from the material containers C1, C2, and C3 smoothly moves to the discharge hole 316A.

In more detail, the height H1 from the top of the accommodation space S3 to the discharge hole 316A may be higher than the height H2 from the top of the accommodation space S3 to the bottom of the fluid supply unit 41 . In addition, the height H1 from the upper end of the accommodation space S3 to the discharge hole 316A may be higher than the height H3 from the upper end of the accommodation space S3 to the lower ends of the perforations 313A and 313B.

Meanwhile, as described above, the container mounting parts 31, 32, and 33 may include outlets 31B, 32B, and 33B for guiding materials or a mixture of water and materials.

The outlets 31B, 32B, and 33B may protrude from the bottom of the container mounting parts 31, 32, and 33. An extraction channel through which a material or a mixture of water and material is guided may be formed at the outlets 31B, 32B, and 33B.

The material containers C1, C2, and C3 may be seated on the container mounting parts 31, 32, and 33. In addition, when the lid 38 covers the container mounting portions 31, 32, and 33 and is in a locked state, the container mounting portion 31, 32, and 33 may further include a material container stopper 317 with which the seating surfaces of the material containers C1, C2, and C3 come into contact, and a pressing portion contact portion 318 that contacts the pressing portions 47A, 47B, and 47C of the lid 38. The material container stopper 317 and the pressing portion contact portion 318 will be described in detail later.

The material receiving body 36 may be formed with at least one container mounting portion 31, 32, 33. The material receiving body 36 may include housings 362A, 362B, and 362C formed to protect outer circumferences of the container mounting portions 31, 32, and 33. At least a portion of each of the container mounting parts 31, 32, and 33 may be accommodated inside the housings 362A, 362B, and 362C. In this case, the outer circumferential surfaces 319C and 319D of the container mounting portion 31 may contact the housing 362A.

A through portion through which the inlets 31A, 32A, and 33A and the outlets 31B, 32B, and 33B pass may be formed in the material receiving body 36 . The housings 362A, 362B, 362C and the penetrating portion fix the container mounting portions 31, 32, and 33 to the material receiving body 36, thereby preventing the container mounting portions 31, 32, and 33 from being separated.

Each of the container mounting portions 31, 32, and 33 may be opened together or closed together by the lid module 37. The sum of the areas of the plurality of container mounting parts 31, 32, and 33 may be smaller than the area of the lid module 37.

Meanwhile, the material supply unit 3 may also include a lead module for each container mounting portion. That is, in the material supply unit 3, one lid module can open and close one container mount. In this case, when three container mounting parts are formed in the material supply unit 3, three lead modules that can rotate independently of each other can be connected to the material receiving body 36. However, when a plurality of lead modules are installed in the material accommodating body 36, the number of parts of the material supply unit 3 is large, and mounting and dismounting of the plurality of material containers may be cumbersome.

On the other hand, when one lead module 37 opens and closes all of the plurality of container mounting parts 31, 32, and 33, the number of parts can be minimized, the structure is simple, and the user can easily handle the material feeder 3. A user can open all of the plurality of container mounting parts 31, 32, and 33 by a simple operation of rotating the lid module 37 upward. In addition, the user can cover all of the plurality of container mounting parts 31, 32, and 33 at once by a simple operation of rotating the lid module 37 in a downward direction.

The lead 38 may be composed of a combination of a plurality of members. For example, the lead 38 may include a lower lead 39 and an upper lead 40 . One of the lower lead 39 and the upper lead 40 may be connected to the material receiving body 36 .

The upper lid 40 may be combined with the lower lid 39 to cover the open upper surface of the lower lid 39 .

Pressing portions 47A, 47B, and 47C may be formed on the lower lid 39 to press the material containers C1, C2, and C3 to the bottom surface 316 when the lid 38 covers the container mounting portions 31, 32, and 33. The pressing parts 47A, 47B, and 47C may protrude downward from the lower surface 391 of the lid module 37, more specifically, the lower lid 39.

The lead module 37 may be connected to the material receiving body 36 through hinges 38A and 38B.

In more detail, the rear end of the material receiving body 36 and the rear end of the lead module 37 may be connected to each other by hinges 38A and 38B.

A hinge shaft 38A may be formed on any one of the lead module 37 and the material receiving body 36 . Hinge shaft 38A may be formed horizontally on any one of the lead module 37 and the material receiving body 36 . A hinge shaft connecting portion 38B rotatably supported by inserting a hinge shaft 38A into the other of the lead module 37 and the material receiving body 36 may be formed.

Hereinafter, for convenience of description, a case in which the hinge shaft 38A is formed in the lead module 37 and the hinge shaft connecting portion 38B is formed in the material receiving body 36 will be described as an example.

The hinge shaft connecting portion 38B may be larger than the hinge shaft 38A so that the hinge shaft 38A is movable inside the hinge shaft connecting portion 38B. The hinge shaft 38 can move between a first position and a second position inside the hinge shaft connecting portion 38B. When the lid module 37 is in an open and unlocked state, the hinge shaft 38A may be located at the first position, and when the lid module 37 is in a locked state, the hinge shaft 37 may be located at the second position.

For example, the hinge shaft connecting portion 38B may be vertically longer than the hinge shaft 38A so that the hinge shaft 38A can move in the vertical direction. In this case, the hinge shaft 38A can move up and down between the upper inner circumferential surface 381 and the lower inner circumferential surface 382 of the hinge shaft connecting portion 38B.

The lead module 37 may be rotated about the hinge axis 38A. In addition, the lead module 37 can move in the vertical direction together with the hinge shaft 38A.

The lead module 37 may further include a connection portion 383 connecting the lead 38, more specifically, the lower lead 39 and the hinge shaft 38A.

One side of the connection part 383 may be connected to the hinge shaft 38A, and the other side may be connected to the lower lead 39.

When the fermentation reed 37 is closed and unlocked by the connection part 383, the bottom surface 391 of the fermentation reed 37 and the upper surface 36A of the material receiving body 36 may be spaced apart from each other. That is, a gap g having a predetermined height may be formed between the lower surface 391 of the fermentation reed 37 and the upper surface 36A of the material receiving body 36.

When the fermentation reed 37 is closed and unlocked, the hinge shaft 38A contacts the upper inner circumferential surface 381 of the hinge shaft connecting portion 38B, and when the fermentation reed 37 is locked, the connecting portion 383 may be formed to a length in contact with the lower inner circumferential surface 382 of the hinge shaft connecting portion 38B.

A recessed portion 384 in contact with the hinge shaft connecting portion 38B may be formed in the lower lead 39 . The recessed portion 384 may be formed by recessing the lower surface of the lower lid 39 upward.

The recessed portion 384 may be formed as a curved surface corresponding to the outer circumferential surface of the upper side of the hinge shaft connecting portion 38B. The recessed portion 384 may face the hinge shaft connecting portion 38B in the vertical direction.

When the lead module 37 is in a locked state, the upper outer circumferential surface of the hinge shaft connecting portion 38B may contact the recessed portion 384, and when the lead module 37 is in an unlocked state, the upper outer circumferential surface of the hinge shaft connecting portion 38B may be spaced apart from the recessed portion 384 in the vertical direction.

Interference with the lower lid 39 of the hinge shaft connecting portion 38B, which is vertically formed, can be prevented by the recessed portion 384 .

Referring to FIG. 9 , the material containers C1, C2, and C3 may be seated on the container mounting parts 31, 32, and 33, respectively.

The material containers C1, C2, and C3 may include a material container body CB, a material container cover CC, and a pressure contact portion CD. The material container body CB, the material container cover CC, and the pressurized contact portion CD seal the beverage material contained in the material containers C1, C2, and C3 from the outside so that it does not deteriorate, or the beverage material. It can be protected from leaking out.

The material container body CB may form a side portion of the material container C1. The material container body CB is implemented as a plastic material such as polypropylene (PP) or polyethylene terephthalate (PET), so that the inside thereof can be effectively protected without being damaged or damaged even with a predetermined impact. Depending on the embodiment, the material container body CB may be made of aluminum or the like.

The material container body CB may include a material container cover junction CB2 to which the material container cover CC is bonded, and a body portion CB1 connected to the material container cover junction CB2 to form a side surface of the material container C1.

The material container cover junction CB2 may be formed to have a predetermined length in the radial direction so that the material container cover CC is effectively joined.

As an example, the outer diameter of the material container cover junction CB2 is formed to be larger than the outer diameter of the body portion CB1, so that the material inside the material containers C1, C2, and C3 remains on the material container cover junction CB2. It can be prevented, and the pressing parts 47A, 47B, and 47C can effectively press the material container cover junction CB2.

The body portion CB1 may be formed to have a narrower width from the material container cover CC toward the pressure contact portion CD. For example, the body portion CB1 may have a cylindrical shape in which the outer diameter and the inner diameter become narrower toward the pressure contact portion CD from the material container cover CC. However, it is not limited thereto.

The material container cover CC may be made of a material that is easily cut by the perforations 313A and 313B of the material supply unit 3 and the fluid supply unit 41 . For example, the material container cover CC may be implemented with a soft material such as aluminum foil or polyethylene film. The strength of the material container cover (CC) may be lower than that of the material container body (CB). In this case, when the material container cover CC is cut by the perforations 313A and 313B and the fluid supply part 41, not only the part in contact with the perforation part 313A and 313B and the fluid supply part 41, but also the portion adjacent thereto and may be cut. Further, when the material is extracted by the fluid supplied into the material containers C1, C2, and C3, the cut area of the material container cover CC may be wider due to the pressure. As a result, the material can flow out more easily through the cutout (perforation) of the material container cover CC.

When the lid module 37 covers the container mounting parts 31, 32, and 33 and is in a locked state, the press contact portion CD is in contact with the press parts 47A, 47B, and 47C of the lid module 37 and can be pressed toward the material receiving body 36.

As at least one of the pressurizing contact portion CD and the material container cover joining portion CB2 is pressed by the pressing portions 47A, 47B, and 47C, the material containers C1, C2, and C3 can move toward the container mounting portions 31, 32, and 33, and the material container cover CC can be punctured by the perforation portions 313A, 313B and the fluid supply portion 41.

The pressure contact portion CD may be made of the same material as the material container body CB.

Materials for preparing beverages may be accommodated in the material containers C1, C2, and C3. The material contained in the material containers C1, C2, and C3 may be in liquid form or powder form.

10 and 11, after the material containers C1, C2, and C3 are seated on the container mounting parts 31, 32, and 33, the user rotates the lid module 37 around the hinge axis 38A to cover the container mounting parts 31, 32, 33, and the material containers C1, (C2, and C3) with the lid module 37.

At this time, the hinge shaft 38A can be rotated while in contact with the upper inner circumferential surface 381 of the hinge shaft connecting portion 38B, and interference between the lead module 37 and the material receiving body 36 can be prevented.

When the lid module 37 is closed but unlocked, the lower surface 391 of the lid module 37 and the upper surface 36A of the material receiving body 36 are spaced apart from each other, and the material containers C1, C2, and C3 may not be perforated while being placed on the perforated parts 313A, 313B and the fluid supply part 41. In addition, the hinge shaft 38A may be in contact with the upper inner circumferential surface 381 of the hinge shaft connecting portion 38B.

When the user rotates the locking manipulation unit 371 of the lead module 37 in the locking direction, the lead module 37 descends and can be locked to the lead receiving body 36 . The detailed configuration and operation of the locking operation unit 371 will be described in detail later.

When the lid module 37 is locked, the lid module 37 moves toward the lid receiving body 36, and the pressing portions 47A, 47B, and 47C of the lid 38 may press down at least one of the pressing contact portion CD and the material container cover bonding portion CB2 of the material containers C1, C2, and C3.

By the pressurization, the material containers C1, C2, and C3 may descend. At this time, the seating surface including the material container cover (CC) of the material container (C1) (C2) (C3) is in contact with the material container stopper 317 of the container mounting portion (31) (32) (33) and can no longer descend, and the material container cover (CC) can be cut by the perforated portions 313A, 313B and the fluid supply portion 41 formed in each container mounting portion 31, 32, and 33.

To this end, the height of the material container stopper 317 based on the base 100 (see FIG. 3) may be formed lower than the height of the upper ends of the perforations 313A and 313B and the fluid supply unit 41.

In addition, at least one hole 411 of the fluid supply unit 41 is formed at a higher position from the base 100 than the material container stopper 317, so that the material containers C1, C2, and C3 may be located inside the material containers C1, C2, and C3 when they contact the material container stopper 317 and do not move any further.

Meanwhile, when the lead module 37 is in a locked state, the hinge shaft 38A descends together with the lead module 37 and may come into contact with the lower inner circumferential surface 382 of the hinge shaft connecting portion 38B. In addition, the bottom surface 391 of the lead module 37 and the top surface 36A of the material receiving body 36 may come into contact with each other.

After the material container cover CC is cut, fluid is introduced through the fluid supply unit 41, and the introduced fluid may be guided into the material containers C1, C2, and C3. The fluid guided into the material container (C1) (C2) (C3) is the beverage material inside the material container (C1) (C2) (C3) through the perforated portion by the perforation portion (313A) (313B) It can be extracted to the outlet portion (31B) (32B) (33B).

Meanwhile, a material container sealing portion 317A may be formed on an upper surface of the material container stopper 317 . When the material containers C1, C2, and C3 are seated on the material container stopper 317 and the material in the material container is extracted by supplying fluid, the material container sealing portion 317A may seal the material to be extracted so as not to leak between the material container stopper 317 and the material containers C1, C2, and C3. Thereby, the cleanliness of the material feeder 3 can be maintained.

In addition, a pressure sealing portion 318A may be formed on an upper surface of the pressing portion contact portion 318 . When material leaks through the gap between the material containers C1, C2, and C3 and the material container stopper 317 despite the fact that the material container sealing portion 317A is formed, the pressure sealing portion 318A can prevent the leaked material from leaking out of the container mounting portions 31, 32, and 33. Accordingly, the cleanliness of the material feeder 3 can be maintained more effectively.

However, it is also possible, of course, that the pressure sealing portion 318A is not provided on the pressing portion contact portion 318 and a seal (not shown) is provided on the pressing portions 47A, 47B, and 47C. The sealing may be provided to surround outer circumferences of the lower sides of the pressing parts 47A, 47B, and 47C, and may come into contact with inner circumferences of the container mounting parts 31, 32, and 33. Accordingly, it is possible to prevent material from leaking between the pressing portions 47A, 47B, and 47C and the container mounting portions 31, 32, and 33.

Meanwhile, a first magnetic body 392 may be disposed in the material accommodating body 36 , and a second magnetic body 393 acting with the first magnetic body 392 and a repulsive force may be disposed in the lead module 37 .

The first magnetic body 392 may be located in front of the container mounting parts 31, 32, and 33, and the second magnetic body 393 may be located in front of the pressing parts 47A, 47B, and 47C. When the lead module 37 is closed, the first magnetic body 392 and the second magnetic body 393 may face each other vertically.

At least one of the first magnetic body 392 and the second magnetic body 393 may include a magnet.

When the first magnetic body 392 and the second magnetic body 393 exert a repulsive force on each other, the lid module 37 may be unlocked more easily. In addition, the gap g between the lower surface 391 of the lid module 37 and the upper surface 39A of the material receiving body 36 can be easily maintained in the unlocked state.

12 is a perspective view of a state in which an upper lead of a lead module having a locking operation unit is removed according to an example.

Hereinafter, FIG. 12 will be described with reference to FIG. 6 .

The beverage maker may include lockers 372A and 372B provided on the lid module 37 . In addition, the beverage maker may include a support groove 361 for supporting the lockers 372A and 372B in an unlocked state, and a locking groove 362 for engaging the lockers 372A and 372B in a locked state.

The lockers 372A and 372B may lock the lid module 37. The lockers 372A and 372B may be movably provided on the lid module 37 .

The lockers 372A and 372B may include a first locker 372A and a second locker 372B. The first locker 372A and the second locker 372B may be positioned opposite to each other with respect to the pressing parts 47A, 47B, and 47C. That is, the first locker 372A may be disposed on one side of the lid module 37, the second locker 372B may be disposed on the other side of the lid module 37, and the pressing parts 47A, 47B, and 47C may be located between the first locker 372A and the second locker 372B.

The first locker 372A and the second locker 372B may move in opposite directions. For example, when the first locker 372A moves forward during a locking operation, the second locker 372B may move backward. Conversely, when the first locker 372A moves backward during an unlocking operation, the second locker 372B can move forward. Accordingly, the locking of the lid module 37 and the material receiving body 36 by the lockers 372A and 372B can be more robust.

Guide holes 379A and 379B for guiding the lockers 372A and 372B may be formed in the lead module 37 . The guide holes 379A and 379B may be formed to penetrate long in the front and rear directions. Guide holes 379A and 379B may be formed in the lower lid 39 .

The lengths of the guide holes 379A and 379B may be longer than those of the lockers 372A and 372B. The guide holes 379A and 379B may be formed as a long penetrating single hole or as a set of relatively short holes spaced apart from each other.

The guide holes 379A and 379B may include a first guide hole 379A for guiding the first locker 372A and at least one second guide hole 379B for guiding the second locker 372B. The first guide hole 379A and the second guide hole 379B may be formed on opposite sides of each other with respect to the pressing parts 47A, 47B, and 47C.

Meanwhile, the lockers 372A and 372B may include a locker body 375, a locking part 376, and an operating protrusion hooking part 377.

At least a part of the rocker body 375 may pass through the guide holes 379A and 379B. An upper part of the rocker body 375 may be located between the lower lid 39 and the upper lid 40, and a lower part may protrude downward from the bottom surface of the lower lid 39 through the guide holes 379A and 379B.

At least one fixing hole 378 formed long in the front-rear direction may be formed in the rocker body 375 . The fixing hole 378 may be located inside the lower lid 39 .

A locker support portion 379 passing through the fixing hole 378 of the lockers 372A and 372B may be formed in the lower lid 39 . The locker support portion 379 is located inside the lower lid 39 and may protrude outward in the radial direction from the upper outer circumference of the pressing portions 47A, 47B, and 47C.

The locker support portion 379 can pass through the fixing hole 378 of the lockers 372A and 372B to support the lockers 372A and 372B in the vertical direction, thereby preventing the lockers 372A and 372B from falling through the guide holes 379A and 379B. In addition, since the fixing hole 378 is formed to be long in the forward and backward directions, when the lockers 372A and 372B move, the locker support 379 moves back and forth with respect to the fixing hole 378, and the movement of the lockers 372A and 372B may not be hindered.

The locking part 376 may protrude downward from the locker body 375 . The locking part 376 is supported by the support groove 361 formed in the material receiving body 36 and can be caught in the locking groove 362 .

Since the locking part 376 is inclined, it can easily move between the support groove 361 (see FIG. 13) and the locking groove 362 (see FIG. 13).

A plurality of locking parts 376 spaced apart from each other may be formed. For example, each of the first locker 372A and the second locker 372B may include three locking parts 376 .

The operating protrusion engaging portion 377 may protrude upward from the rocker body 375 . The operating protrusion hooking portion 377 can be caught on the operating protrusion engaging portions 374A and 374B, which will be described later, so that the locking operation unit 371, in detail, the rotational force of the handle 372 is transmitted to the lockers 372A and 372B, so that the lockers 372A and 372B can move forward and backward.

Meanwhile, the locking control unit 371 may include a handle 372, a rotating body 373, and control protrusions 374A and 374B.

The handle 372 is rotatably provided on the upper lid 40, and the user can lock/unlock the lid module 37 by holding and turning the handle 372. Rotating the handle 372 in one direction (eg, clockwise) may lock the lid module 37, and rotating the handle 372 in the opposite direction (eg, counterclockwise) may unlock the lid module 37.

The rotating body 373 is disposed below the handle 372 and can rotate together with the handle 372 . The rotating body 372 may be positioned above one of the plurality of pressing parts 47A, 47B, and 47C, or may be disposed to surround an outer circumference of any one pressing part. The rotating body 373 may be located inside the lower lid 39 .

The manipulation protrusions 374A and 374B may protrude from the outer circumference of the rotating body 373 . The control protrusions 374A and 374B may move the lockers 372A and 372B according to the rotation of the handle 372 and the rotating body 373 . The operating protrusions 374A and 374B may move the lockers 372A and 372B by pushing the operating protrusion engaging portions 377 of the lockers 372A and 372B.

The manipulation protrusions 374A and 374B may include a first manipulation protrusion 374A that moves the first locker 372A and a second manipulation protrusion 374B that moves the second rocker 372B.

Each of the manipulation protrusions 374A and 374B may include an unlocking protrusion 374C that pushes the lockers 372A and 372B in one direction when the rotating body 373 rotates in one direction, and a locking protrusion 374D that pushes the lockers 372A and 372B in the opposite direction when the rotating body 373 rotates in the other direction. The unlocking protrusion 374C and the locking protrusion 374D may be spaced apart from each other.

The unlocking protrusion 374C of the first manipulation protrusion 374A and the unlocking protrusion 374C of the second manipulation protrusion 374B may be formed at symmetrical positions with respect to the center of the rotating body 373. Similarly, the locking protrusion 374D of the first manipulation protrusion 374A and the locking protrusion 374D of the second manipulation protrusion 374B may be formed at symmetrical positions with respect to the center of the rotating body 373.

For example, when the user rotates the handle 372 clockwise, the rotating body 373 rotates, the locking protrusion 374D of the first operating protrusion 374A pushes the protrusion engaging portion 377 of the first locker 372A forward, and the locking protrusion 374D of the second operating protrusion 374B moves the protrusion engaging portion 377 of the second locker 372B. ) can be pushed backwards.

Conversely, when the user rotates the handle 372 in a counterclockwise direction, the rotating body 373 rotates, the unlocking protrusion 374C of the first operating protrusion 374A pushes the operating protrusion engaging portion 377 of the first locker 372A backward, and the unlocking protrusion 374C of the second operating protrusion 374B moves the operating protrusion engaging portion 37 of the second locker 372B. 7) can be pushed forward.

Accordingly, the first locker 372A and the second locker 372B moving in opposite directions can be simultaneously and easily operated by manipulating the single handle 372 .

13 is a view showing a material feeder in an unlocked state in which the locking part is supported in the support groove, and FIG. 14 is a view showing a material feeder in a locked state in which the locking part is engaged in the locking groove.

13 and 14 are shown based on the locking part 376 of the first locker 372A, but those skilled in the art will be able to easily understand the second locker 372B (see FIG. 6) based on the above description.

At least one support groove 361 for supporting the locking part 376 of the lockers 372A and 372B and at least one locking groove 362 for engaging the locking part 376 may be formed in the material receiving body 36.

When the lead module 37 is closed but unlocked, the locking part 376 may be supported by the support groove 361 . The support groove 361 may be formed by being depressed downward in the upper surface 36A of the material receiving body 36.

When the lead module 37 is closed and in a locked state, the locking part 376 may be caught and fixed by the locking groove 362 . The locking groove 362 may communicate with the support groove 361 and may be formed to be stepped downward with respect to the support groove 361 .

The vertical distance H1 between the upper surface 36A of the material accommodating body 36 and the support groove 361 may be shorter than the vertical distance between the upper surface of the material accommodating body 36 and the locking groove H2. Therefore, when the locking part 376 moves from the support groove 361 to the locking groove 362, the lead module 37 can move downward, and when the locking part 376 moves from the locking groove 362 to the support groove 361, the lead module 37 can move upward.

Therefore, even if the user does not apply a sufficient downward pressing force to the lid module 37 during the locking operation, the lid module 37 is lowered and can be easily locked, and the container mounting parts 31, 32, 33 are completely sealed, so reliability can be improved.

In addition, even if the user does not apply a sufficient upward pulling force to the lid module 37 during the unlocking operation, the lid module 37 rises and can be easily unlocked, and the sealing of the container mounting parts 31, 32, and 33 can be easily released.

The lower surface of the support groove 361 may be inclined downward toward the locking groove, and the inclined locking part 376 may be stably supported.

The upper surface of the support groove 361 may be open, so that the locking part 376 may not be restrained in the vertical direction.

When the locking part 376 is caught in the locking groove 362, the locking part 376 may be constrained between the top surface 362A and the bottom surface of the locking groove 362. Accordingly, the locking portion 376 is constrained in the vertical direction, and opening of the lid module 37 can be limited.

A guide groove 363 may be formed between the support groove 361 and the locking groove 362 . During the locking operation of the locking manipulation unit 371, the locking unit 376 located in the support groove 361 may pass through the guide groove 363 and move to the locking groove 362. During an unlocking operation of the locking manipulation unit 371 , the locking unit 376 located in the locking groove 362 may pass through the guide groove 363 and move to the support groove 361 .

The bottom surface of the guide groove 363 may include a flat surface and an inclined surface. The plane may be close to the support groove 361 and the inclined surface may be close to the locking groove 362 . The lower end of the locking part 376 supported by the support groove 361 can be stably supported by the plane, and the locking part 376 can be easily moved from the support groove 361 to the locking groove 362 by the inclined surface.

Meanwhile, the locking portion 376 of the first locker 371A and the locking portion 376 of the second locker 372B may be inclined in opposite directions. For example, the locking portion 376 of the first locker 371A may be inclined downward toward the front as shown in FIGS. 13 and 14 . Conversely, the locking portion 376 of the second locker 372B may be inclined downward toward the rear.

6, at least one first support groove supporting the locking portion 376 of the first locker 372A and at least one second support groove supporting the locking portion 376 of the second locker 372B may be formed in the material receiving body 36, respectively. In addition, the material accommodating body 36 may have at least one first catching groove for engaging the locking part 376 of the first locker 372A and at least one second catching groove for engaging the locking part 376 of the second locker 372B.

The number of first support grooves and first locking grooves may be the same as the number of locking parts 376 of the first locker 372A, and the number of second support grooves and second locking grooves may be the same as the number of locking parts 376 of the second locker 372B. For example, each of three first support grooves, second support grooves, first locking grooves, and second locking grooves may be formed in the material receiving body 36 .

Based on the container mounting parts 31, 32, and 33, the first support groove and the second support groove may be located on opposite sides of each other, and the first locking groove and the second locking groove may also be located on opposite sides of each other.

13 and 14, the front and rear distance L1 between the front surface of the material receiving body 36 and the first support groove may be longer than the front and rear distance between the front surface of the material receiving body 36 and the first locking groove. Accordingly, when the first locker 372A moves forward, the locking part 376 of the first locker 372A can move from the first support groove to the first locking groove.

Conversely, the front and rear distance between the front surface of the material receiving body 36 and the second support groove may be closer than the front and back distance between the front surface of the material receiving body 36 and the second locking groove. Accordingly, when the second locker 372B retreats, the locking part 376 of the second locker 372B can move from the second support groove to the second locking groove.

As a result, each locking part 376 of the first locker 372A and the second locker 372B moving in opposite directions can be easily caught in each locking groove and locked.

15 is a perspective view of a state in which an upper lid of a lead module having a locking operation unit is removed according to another embodiment, and FIG. 16 is a perspective view of a state in which a handle of the locking operation unit shown in FIG. 15 is removed.

Hereinafter, contents overlapping with those described above will be omitted, and description will focus on the differences.

The locking operation unit 371 according to the present embodiment may include a handle 372 and a power transmission unit 380 that transmits rotational force of the handle 372 to the lockers 372A and 372B.

The power transmission unit 380 may be disposed between the upper lead 40 and the lower lead 39 . At least a portion of the power transmission unit 380 may be located below the handle 372 .

The power transmission unit 380 may include a rotating gear 381 and a pinion gear 382 . However, the power transmission unit 380 does not include the pinion gear 382, and the rotating gear 371 is gear-engaged directly with the rack gear unit 384, or transmits the rotational force of the rotating gear 371 to the pinion gear 372. Of course, it is also possible to further include at least one gear.

Hereinafter, a case in which the rotating gear 381 is gear-coupled with the pinion gear 382 and the pinion gear 382 is gear-coupled with the rack gear portion 384 of the lockers 372A and 372B will be described.

The rotating gear 381 is located on the lower side of the handle 372 and can rotate together with the handle 372 .

The pinion gear 382 may be gear-coupled with the rotating gear 381 . The pinion gear 382 may be located behind the rotating gear 381 .

When the user rotates the handle 372, the rotating gear 381 rotates together with the handle 372, and the rotational force of the rotating gear 381 is transmitted to the pinion gear 382 so that the pinion gear 382 can rotate.

The pinion gear 382 may have a larger diameter than the rotating gear 381 . The diameter of the pinion gear 382 may be formed to a size that is gear-coupled with the rack gear portion 384 of the lockers 372A and 372B. The diameter of the pinion gear 382 may correspond to the distance between the rack gear part 384 of the first rocker 372A and the rack gear part 384 of the second rocker 372B.

The lockers 372A and 372B according to this embodiment may include a locker body 375, a locking part 376, and a rack gear part 374. Since the contents of the locker body 375 and the locking part 376 are the same as those described above, they are omitted.

The rack gear unit 374 may be gear-coupled with the pinion gear 382 . The rack gear part 374 may be formed on the rocker body 375 and may be formed to face the pinion gear 382 . The rack gear unit 374 may be integrally formed with the rocker body 375 .

The rack gear unit 374 may be located between the upper lead 40 and the lower lead 39 .

The pinion gear 382 may be gear-coupled to the rack gear part 384 of the first rocker 372A and the rack gear part 384 of the second rocker 372B, respectively. The rotational force of the pinion gear 382 may be transmitted to the rack gear unit 384 of the first locker 372A and the rack gear unit 384 of the second locker 372B, respectively.

Since the rack gear part 384 of the first locker 372A and the rack gear part 384 of the second locker 372B are located on opposite sides of the pinion gear 382, when the pinion gear 382 rotates, the rack gear part 384 of the first locker 372A and the rack gear part 384 of the second rocker 372B can move opposite to each other.

For example, when the user rotates the handle 372 in one direction (eg, clockwise), the rack gear unit 384 of the first locker 372A moves backward, and the rack gear unit 384 of the second locker 372B can move forward.

On the other hand, when the user rotates the handle 372 in the opposite direction (for example, counterclockwise), the rack gear part 384 of the first locker 372A moves forward, and the rack gear part 384 of the second locker 372B can move backward.

Accordingly, the first locker 372A and the second locker 372B moving in opposite directions can be simultaneously and easily operated by manipulating the single handle 372 .

17 is a view for explaining a modified example of a hinge shaft and a hinge shaft connecting portion.

A first hinge magnetic body 394 may be disposed at the hinge shaft connecting portion 38B, and a second hinge magnetic body 395 may be disposed at the hinge shaft 38A.

At least one of the first hinge magnetic body 394 and the second hinge magnetic body 395 may include a magnet. The first hinge magnetic body 394 and the second hinge magnetic body 395 may have an attractive force acting on each other.

The first hinge magnetic body 394 may be positioned lower than the second hinge magnetic body 395 . As a result, the mutual attractive force may be relatively large in the locked state of the lead module 37, and the mutual attractive force may be relatively small in the unlocked state.

The first hinge magnetic body 394 and the second hinge magnetic body 395 may face each other.

The first hinge magnetic body 394 and the second hinge magnetic body 395 may be inclined. In this case, the slopes of the first hinge magnetic body 394 and the second hinge magnetic body 395 may be the same.

When the first hinge magnetic body 394 and the second hinge magnetic body 395 act on each other, locking of the lead module 37 may be more robust.

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

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