In the following description, members and parts having the same functions are denoted by the same reference numerals, and repeated descriptions of members and parts denoted by the same reference numerals are omitted. In addition, in the following embodiment, a drink is "beer", for example. When the beverage is "beer", the word "beverage" in the following embodiments is read as "beer". "Beer" is, for example, alcoholic beer. Also, the beverage in the embodiment may be a sparkling beverage other than beer (for example, a sparkling alcoholic beverage other than beer or a sparkling non-alcoholic beverage).

(First embodiment)
A method of using the beverage server in the first embodiment will be described with reference to FIGS. 1 to 3. FIG. FIG. 1 is a flow chart showing an example of how to use the beverage server according to the first embodiment. FIG. 2 is a schematic diagram showing each step of the usage method of the beverage server in the first embodiment. FIG. 3 is a diagram schematically showing an example of a beverage or foam pouring mechanism.

In the first step ST1, the beverage B is poured out from the pouring port 21 of the beverage pouring part 20. As shown in FIG. FIG. 2(a) shows a state in which the first step ST1 (beverage dispensing step) is being executed.

In the second step ST2, the foam F is poured out from the pouring port 21 of the beverage pouring part 20. As shown in FIG. FIG. 2(b) shows a state during execution of the second step ST2 (bubble pouring step).

After execution of the second step ST<b>2 , bubbles remain in the first flow path 23 of the beverage extraction part 20 . FIG. 2(c) shows the state after execution of the second step ST2 (bubble pouring step). In general, the finer the texture, the easier it is for bubbles to remain in the first flow path 23, and the coarser the texture, the less likely it is for the foam to remain in the first flow path 23. However, in the first embodiment, the size (fineness of texture) of the bubbles remaining in the first channel 23 is not limited.

In the third step ST3, the foam F remaining in the first channel 23 of the beverage extraction part 20 is removed. FIG. 2(d) shows a state during execution of the third step ST3 (bubble removal step). As shown in FIG. 2(d), the foam F is removed from the first channel 23 by executing the third step ST3. In addition, in the third step ST3, it is preferable that the bubbles remaining in the first flow path 23 are completely removed.

3rd step ST3 is performed by introduce|transducing the pressurized gas G into the 1st flow path 23. As shown in FIG. More specifically, by introducing the pressurized gas G into the first flow path 23 , the bubbles F remaining in the first flow path 23 are pushed out from the first flow path 23 by the pressurized gas G.

By executing the first step ST1 to the third step ST3, the beverage and foam are poured from the beverage server (more specifically, the outlet 21) into a drink container such as a glass or mug. Note that the foam F removed from the first channel 23 by the execution of the third step ST3 may be poured into a drink container such as a glass or mug, or may not be poured into the drink container. Execution of the first step ST1 to the third step ST3 corresponds to execution of one cycle (for example, the first cycle) of how to use the beverage server. In the first cycle, one beverage container is dispensed with beverage and foam.

In the fourth step ST4, the beverage B is poured out from the pouring port 21 of the beverage pouring part 20. As shown in FIG. 4th step ST4 is performed after 3rd step ST3 (bubble removal process). Since the foam remaining in the beverage extraction part 20 is removed before the execution of the fourth step ST4, it is suppressed from being mixed with the beverage during the execution of the fourth step ST4. A fourth step ST4, a fifth step ST5, and a sixth step ST6 are processes similar to the first step ST1, the second step ST2, and the third step ST3, respectively. Execution of the fourth step ST4 to sixth step ST6 corresponds to execution of one cycle (for example, the second cycle) of the method of using the beverage server. In the second cycle, another beverage container is dispensed with beverage and foam.

In the usage method of the beverage server in the first embodiment, a cycle consisting of first step ST1 to third step ST3 is repeatedly executed. It should be noted that between cycles the beverage container receiving the beverage and foam is different.

The method of using the beverage server in the first embodiment comprises a foam removal step of removing foam remaining in the first flow path within the beverage dispensing section. Therefore, when the beverage is poured into the beverage container in one cycle, the bubbles remaining in the beverage dispensing portion are prevented from being mixed with the beverage. As a result, in the initial stage of pouring the beverage into the drink container, bubbles are prevented from entering the drink container, and excessive foaming of the drink in the drink container due to bubbles being generated is suppressed.

In the method of using the beverage server in the first embodiment, the foam remaining in the first channel inside the beverage dispensing section is forcibly removed. For this reason, the problem that bubbles are likely to mix into the beverage at the initial stage of pouring out the beverage is fundamentally solved. On the other hand, the technique of physically separating the foam flow path and the beverage flow path does not solve the problem of foam remaining in the flow path (foam flow path). Therefore, the foam remaining in the flow path is removed from the gap between the flow paths (the gap between the flow path for foam and the flow path for beverage) or the wall surface between the outlets (between the beverage outlet and the foam outlet). contamination of the beverage via the walls between the In addition, it is not preferable from a sanitary point of view that bubbles remain in the channel (channel for foam) for a long period of time. The method of using the beverage server in the first embodiment solves the problem of foam mixing into the beverage, and is also hygienically preferable because the foam remaining in the flow channel is forcibly removed.

In addition, in the example shown in FIG. 2, the outlet 21 serves as both a beverage outlet and a foam outlet. For this reason, the structure of the beverage extraction part 20 becomes simple.

As shown in Figure 3, the beverage server in the first embodiment may comprise a pump 40a. In this case, the above-described beverage pouring step (in other words, the first step ST1 or the fourth step ST4) increases the pressure in the beverage storage container C using the pump 40a such as an electric pump. It may involve pushing the beverage from the beverage storage container C into the beverage dispensing portion 20 . The beverage storage container C is, for example, a container made of stainless steel such as a PET bottle, a can such as an aluminum can, or a beer barrel. The capacity of the beverage storage container C is, for example, 1 liter or more and 20 liters or less, 1 liter or more and 10 liters or less, 1 liter or more and 5 liters or less, 1 liter or more and 3 liters or less.

Alternatively or additionally, the foam removal step described above (in other words, the third step ST3 or the sixth step ST6) is applied to the first flow path 23 using a pump 40a such as an electric pump. Providing pressurized gas may be included.

The pump for sending the pressurized gas to the first flow path 23 and the pump for increasing the pressure in the beverage storage container C are preferably the same pump. To remove foam from the first flow path 23 by using the same pump for sending pressurized gas to the first flow path 23 and for increasing the pressure in the beverage storage container C. This suppresses an increase in weight or complication of the structure of the entire beverage server when adding the foam removing mechanism.

(Second embodiment)
A beverage server 1A in the second embodiment will be described with reference to FIG. FIG. 4 is a schematic cross-sectional view schematically showing a beverage server 1A according to the second embodiment.

A beverage server 1A in the second embodiment includes a beverage server main body 10, a beverage pouring section 20, and a pressurized gas supply section 40 that supplies pressurized gas to a first flow path 23 of the beverage pouring section 20. Prepare.

In the example shown in FIG. 4, a beverage storage container C is arranged inside the beverage server body 10 . The beverage server main body 10 may include a cooling mechanism for cooling the beverage in the beverage storage container C. Alternatively, a cooling pipe may be arranged in the beverage server main body 10, and the beverage may be supplied to the cooling pipe from a beverage storage container C outside the beverage server main body. Therefore, the beverage server main body 10 may be a housing that can accommodate the beverage storage container C, or may be a housing that incorporates a cooling pipe.

The beverage pouring unit 20 is a portion of the beverage server 1A that corresponds to a mechanism for pouring out beverages or foam. In the example illustrated in FIG. 4 , the beverage dispensing portion 20 includes at least a first flow path 23 and a foam generating portion 25 that generates foam within the first flow path 23 . The beverage dispensing part 20 may include at least one of a beverage supply channel 31, a gas supply channel 32, and a pressurized gas supply part 40 (for example, a pump 40a).

A spout 21 is provided at the tip of the first channel 23 . The first channel 23 is the channel through which the beverage or foam passes, and the outlet 21 is the outlet through which the beverage or foam is poured.

In the example shown in FIG. 4, when the beverage supply channel 31 and the first channel 23 are in communication (for example, when the first valve V1 described later is in an open state), the first channel 23 is supplied with a beverage. Beverage is supplied from the channel 31 . At this time, foam is poured out from the spout 21 when the foam generating part 25 is in the operating state, and the beverage is poured out from the spout 21 when the foam producing part 25 is in the non-operating state.

In the example shown in FIG. 4, when the gas supply channel 32 and the first channel 23 are in communication (for example, when the second valve V2 described later is in an open state), the gas is supplied to the first channel 23. Pressurized gas is supplied from the flow path 32 . As a result, the bubbles remaining in the first flow path 23 are discharged from the spout 21 together with the pressurized gas.

The bubble generator 25 generates bubbles inside the first flow path 23 . In the example shown in FIG. 4, the bubble generator 25 includes an ultrasonic transducer 25a. The ultrasonic transducer 25a is arranged in contact with a first pipe 23p that defines the first flow path 23, for example. In addition, it is preferable that the hard portion H be a portion of the first pipe 23p that contacts the ultrasonic transducer 25a. When the bubble generator 25 includes the ultrasonic vibrator 25a, the active state of the foam generator 25 corresponds to the vibrating state of the ultrasonic vibrator 25a. Being there corresponds to the ultrasonic transducer 25a being in a non-vibrating state.

In the example shown in FIG. 4, the vibration of the ultrasonic transducer 25a causes the vibration to be transmitted to the beverage in the first flow path 23, and as a result of the transmission of the vibration to the beverage, bubbles are generated from the beverage in the first flow path 23. generated. When bubbles are generated by the ultrasonic transducer 25a, there is no need to complicate the shape of the first channel 23 for generating bubbles. In particular, when the first pipe 23p that defines the first flow path 23 is a replaceable replacement part (for example, a disposable part), the manufacturing cost of the replacement part is reduced. However, the generation of bubbles in the second embodiment is not limited to the generation of bubbles by the ultrasonic transducer 25a. The generation of bubbles may be performed using means other than the ultrasonic transducer 25a.

The pressurized gas supply unit 40 supplies pressurized gas to the first channel 23 through the gas supply channel 32 . The pressurized gas supply unit 40 includes, for example, a pump 40a such as an electric pump. When the pressurized gas is supplied by the pump 40 a , the pressurized gas can be stably sent to the first flow path 23 . By stably supplying the pressurized gas to the first flow path 23, the bubbles remaining in the first flow path 23 can be reliably removed. The pressurized gas is supplied to the pump 40a through, for example, an air supply pipe 41p one end of which is open to the atmosphere. In this case, the pressurized gas supplied to the first flow path 23 by the pump 40a is air.

In the example shown in FIG. 4 , the pump 40 a can supply pressurized gas directly to the gas supply channel 32 . More specifically, the first end E1 of the gas pipe 32p that defines the gas supply channel 32 is connected to the pump 40a, and the second end E2 of the gas pipe 32p defines the first channel 23. It is arranged in contact with the pipe 23p. The beverage flows from the first channel 23 to the gas supply channel 32 at the connecting portion between the gas pipe 32p and the first pipe 23p (more specifically, the second end E2 of the gas pipe 32p). A check valve V3 is preferably arranged to prevent reverse flow. In addition, a sealing member S1 for preventing leakage of the beverage or pressurized gas is provided at the connecting portion between the gas pipe 32p and the first pipe 23p (more specifically, the second end E2 of the gas pipe 32p). is preferably arranged. The seal member S1 may be a seal member incorporating a check valve V3.

In the example shown in FIG. 4, the gas pipe 32p is a branch pipe, and the gas pipe 32p includes a first branch pipe 32p-1 extending from the branch portion 32s to the first pipe 23p and a beverage storage pipe extending from the branch portion 32s. and a second branch pipe 32p-2 extending toward the container C. The end of the second branch pipe 32p-2 (in other words, the third end E3 of the gas pipe 32p) is placed in contact with the lid member CP of the beverage storage container C. As shown in FIG. A seal member S2 is arranged at the end of the second branch pipe 32p-2 (in other words, the third end E3 of the gas pipe 32p) to be in close contact with the lid member CP.

In the example illustrated in FIG. 4 , the beverage server 1A includes a first valve V1 that opens and closes the beverage supply channel 31 and a second valve V2 that opens and closes the gas supply channel 32 .

As a method for opening and closing the beverage supply channel 31 by the first valve V1, any known method can be adopted. For example, the first valve V1 may be a valve (for example, an electromagnetic valve) capable of crushing the beverage pipe 31p defining the beverage supply channel 31 . It should be noted that the first valve V1 does not necessarily have to be an electromagnetic valve, and may be an electric valve or a mechanical valve that is opened and closed by operating an operation unit. Further, the first valve V1 may be a valve that acts on the beverage supply channel 31 from the outside of the beverage pipe 31p, or may be a valve built into the beverage pipe 31p. In the example shown in FIG. 4, the first end E4 of the beverage line 31p is inserted into the beverage storage container C and the second end E5 of the beverage line 31p is the first line defining the first flow path 23. 23p.

As a method for opening and closing the gas supply channel 32 by the second valve V2, any known method can be adopted. For example, the second valve V2 may be a valve (for example, an electromagnetic valve) capable of crushing the gas pipe 32p that defines the gas supply channel 32 . It should be noted that the second valve V2 does not necessarily have to be an electromagnetic valve, and may be an electric valve or a mechanical valve that is opened and closed by operating an operation unit. Further, the second valve V2 may be a valve that acts on the gas supply passage 32 from the outside of the gas pipe 32p, or may be a valve built into the gas pipe 32p.

In the example shown in FIG. 4, the beverage dispensing unit 20 has a beverage or foam supply mode in which the first valve V1 is opened, the second valve V2 is closed, and the pump 40a is driven; It is possible to execute a foam removal mode in which the second valve V2 is opened, the first valve V1 is closed, and the pump 40a is driven.

When the beverage server 1A includes the ultrasonic transducer 25a, the beverage dispensing unit 20 opens the first valve V1, closes the second valve V2, and deactivates the ultrasonic transducer 25a. and a beverage supply mode in which the pump 40a is driven, the first valve V1 is opened, the second valve V2 is closed, the ultrasonic vibrator 25a is activated, and the pump 40a is turned on. It is preferable to be able to execute a foam supply mode in which the second valve V2 is opened, the first valve V1 is closed, and the pump 40a is in a driven state.

In the beverage server 1</b>A of the second embodiment, the pressurized gas is supplied from the pressurized gas supply unit 40 to the first channel 23 to remove bubbles remaining in the first channel 23 . Therefore, the second embodiment has the same effect as the first embodiment.

(How to use the beverage server in the second embodiment)
A method of using the beverage server 1A in the second embodiment will be described with reference to FIGS. 4 to 8. FIG. FIG. 5A is a flow chart showing an example of how to use the beverage server 1A in the second embodiment. FIG. 5B is a diagram schematically showing an example of a mode executable by the beverage dispensing section 20. FIG. 6 to 8 are diagrams schematically showing one process of how to use the beverage server 1A.

In the first step ST101 (beverage pouring step), the beverage is poured from the pouring port 21 of the beverage pouring part 20 .

In the first step ST101, the beverage pouring mode is executed according to the operation of the operation section (not shown). In the beverage dispensing mode, the first valve V1 is opened, the second valve V2 is closed, the foam generator 25 (more specifically, the ultrasonic transducer 25a) is deactivated, Also, the pump 40a is activated.

In the beverage dispensing mode, the pump 40a supplies pressurized gas to the pressurization chamber CB via the gas pipe 32p (more specifically, the second branch pipe 32p-2). In the example shown in FIG. 4, the pressurization chamber CB is a gas chamber within the beverage reservoir C. In the example shown in FIG. Alternatively, the pressurized gas may be supplied into the pressurized chamber containing the entire beverage storage container C with the lid open.

When pressurized gas is supplied into the pressurization chamber, the pressure of the pressurized gas pushes the beverage out of the beverage storage container C. As shown in FIG. The extruded beverage passes through the beverage supply channel 31 and the first channel 23 and is poured out from the outlet 21 .

In the second step ST102 (foam pouring step), foam is poured from the pouring port 21 of the beverage pouring part 20 .

In the second step ST102, the foam pouring mode is executed according to the operation of the operating section (not shown). In the foam pouring mode, the first valve V1 is opened, the second valve V2 is closed, the foam generator 25 (more specifically, the ultrasonic transducer 25a) is activated, and , the pump 40a is activated.

In the foam dispensing mode, the pump 40a supplies pressurized gas to the pressurizing chamber CB via the gas pipe 32p (more specifically, the second branch pipe 32p-2).

When pressurized gas is supplied into the pressurized chamber CB, the beverage is pushed out of the beverage storage container C by the pressure of the pressurized gas. The extruded beverage flows through the beverage supply channel 31 into the first channel 23 . In the bubble ejection mode, the bubble generator 25 (more specifically, the ultrasonic transducer 25 a ) is in an operating state, so bubbles are generated in the first flow path 23 by the bubble generator 25 . The foam generated in the first channel 23 passes through the first channel 23 and is discharged from the outlet 21 .

In the third step ST103 (foam removing step), the foam remaining in the first flow path 23 of the beverage dispensing portion 20 is removed.

In the third step ST103, the bubble removal mode is executed according to the operation of the operation section (not shown). In the bubble removal mode, the second valve V2 is opened, the first valve V1 is closed, and the bubble generator 25 (more specifically, the ultrasonic transducer 25a) is activated or deactivated. and the pump 40a is activated or deactivated. When the pump 40a is inactive, the foam in the first channel 23 is forced out by the residual pressure in the beverage storage container C.

In the bubble removal mode, the pump 40a supplies pressurized gas to the first flow path 23 via the gas pipe 32p (more specifically, the first branch pipe 32p-1).

When the pressurized gas is supplied to the first flow path 23 , the bubbles remaining in the first flow path 23 are pushed out from the spout 21 by the pressurized gas.

A cycle consisting of the above-described first step ST101 to third step ST103 is repeatedly executed, and the beverage container for receiving the beverage or foam to be poured out from the outlet 21 is replaced between cycles.

In the fourth step ST104, the beverage storage container C (for example, the beverage storage container C housed inside the beverage server main body 10) is replaced with a new beverage storage container. The replacement timing is, for example, when the remaining amount of beverage in the beverage storage container C becomes zero (including substantially zero).

In the second embodiment, the wetted part PA including the first pipe 23p that defines the first flow path 23 may be replaced or cleaned in accordance with the replacement timing of the beverage storage container C. The wetted part PA including the first pipe 23p may be replaced or cleaned.

In the example shown in FIGS. 6 to 8, the liquid contacting part PA including the first pipe 23p (or the liquid contacting part PA including the drink pipe 31p and the first pipe 23p) is connected to the beverage server main body 10 together with the beverage storage container C. taken out from After that, the wetted part PA is washed and reused, or the wetted part PA is replaced with a new wetted part.

In the fourth step ST104, first, the lid portion 10b of the beverage server main body 10 is opened. In the example shown in FIG. 6, the lid portion 10b of the beverage server main body 10 is hinged to the base portion 10a of the beverage server main body 10. As shown in FIG. Therefore, the lid portion 10b is opened by rotating the lid portion 10b about the hinge axis AX with respect to the base portion 10a.

Next, as shown in FIG. 7 , the beverage storage container C and the wetted parts PA are integrally taken out from the beverage server body 10 . The beverage reservoir C and wetted parts PA may then be separated, as shown in FIG. In addition, in the example shown in FIG. 8, the wetted part PA includes a lid member CP attached to the beverage storage container C. As shown in FIG.

The ultrasonic transducer 25a is arranged in contact with a first pipe 23p that defines the first flow path 23, for example. It should be noted that the portion of the first pipe 23p that contacts the ultrasonic transducer 25a is preferably a hard portion (for example, hard resin). Note that the generation of bubbles in the third embodiment is not limited to the generation of bubbles by the ultrasonic transducer 25a. The generation of bubbles may be performed using means other than the ultrasonic transducer 25a.

The pressurized gas supply unit 40 supplies pressurized gas to the first channel 23 via the pressurization chamber CB and the gas supply channel 32 . The pressurized gas supply unit 40 includes, for example, a pump 40a such as an electric pump.

In the example shown in FIG. 9, the pump 40a supplies pressurized gas to the gas supply channel 32 via the pressurization chamber CB.

More specifically, the first end E6 of the first gas pipe 33p that supplies gas to the pressurizing chamber CB is connected to the pump 40a, and the second end E7 of the first gas pipe 33p is connected to the pressurizing chamber CB. communicate.

It is preferable to be able to execute a foam supply mode in which the second valve V2 is opened, the first valve V1 is closed, and the pump 40a is in a driven state.

In the beverage server 1</b>B of the third embodiment, the pressurized gas is supplied from the pressurized gas supply unit 40 to the first flow path 23 to remove bubbles remaining in the first flow path 23 . Therefore, the third embodiment has effects similar to those of the first and second embodiments.

(How to use the beverage server in the third embodiment)
A method of using the beverage server 1B in the third embodiment will be described with reference to FIGS. 5, 9, and 10 to 12. FIG. FIG. 5A is a flow chart showing an example of how to use the beverage server 1B in the third embodiment. FIG. 5B is a diagram schematically showing an example of a mode executable by the beverage dispensing section 20. FIG. 10 to 12 are diagrams schematically showing one process of how to use the beverage server 1B.

In the first step ST101 (beverage pouring step), the beverage is poured from the pouring port 21 of the beverage pouring part 20 .

In the first step ST101, the beverage pouring mode is executed according to the operation of the operation section (not shown). In the beverage dispensing mode, the first valve V1 is opened, the second valve V2 is closed, the foam generator 25 (more specifically, the ultrasonic transducer 25a) is deactivated, Also, the pump 40a is activated.

In the beverage dispensing mode, the pump 40a supplies pressurized gas to the pressurized chamber CB via the first gas pipe 33p. In the example shown in FIG. 9, the pressurization chamber CB is a gas chamber within the beverage reservoir C. In the example shown in FIG. Alternatively, the pressurized gas may be supplied into the pressurized chamber containing the entire beverage storage container C with the lid open.

When pressurized gas is supplied into the pressurization chamber, the pressure of the pressurized gas pushes the beverage out of the beverage storage container C. As shown in FIG. The extruded beverage passes through the beverage supply channel 31 and the first channel 23 and is poured out from the outlet 21 .

In the second step ST102 (foam pouring step), foam is poured from the pouring port 21 of the beverage pouring part 20 .

In the second step ST102, the foam pouring mode is executed according to the operation of the operating section (not shown). In the foam pouring mode, the first valve V1 is opened, the second valve V2 is closed, the foam generator 25 (more specifically, the ultrasonic transducer 25a) is activated, and , the pump 40a is activated.

In the foam extraction mode, the pump 40a supplies pressurized gas to the pressurized chamber CB through the first gas pipe 33p.

When pressurized gas is supplied into the pressurization chamber, the pressure of the pressurized gas pushes the beverage out of the beverage storage container C. As shown in FIG. The extruded beverage flows through the beverage supply channel 31 into the first channel 23 . In the bubble ejection mode, the bubble generator 25 (more specifically, the ultrasonic transducer 25 a ) is in an operating state, so bubbles are generated in the first flow path 23 by the bubble generator 25 . The foam generated in the first channel 23 passes through the first channel 23 and is discharged from the outlet 21 .

In the third step ST103 (foam removing step), the foam remaining in the first flow path 23 of the beverage dispensing portion 20 is removed.

In the third step ST103, the bubble removal mode is executed according to the operation of the operation section (not shown). In the bubble removal mode, the second valve V2 is opened, the first valve V1 is closed, and the bubble generator 25 (more specifically, the ultrasonic transducer 25a) is activated or deactivated. and the pump 40a is activated.

In the bubble removal mode, the pump 40a supplies pressurized gas to the first flow path 23 via the first gas line 33p, the pressurization chamber CB, and the second gas line 32p' defining the gas supply flow path 32. supply.

When the pressurized gas is supplied to the first flow path 23 , the bubbles remaining in the first flow path 23 are pushed out from the spout 21 by the pressurized gas.

A cycle consisting of the above-described first step ST101 to third step ST103 is repeatedly executed, and the beverage container for receiving the beverage or foam to be poured out from the outlet 21 is replaced between cycles.

In the fourth step ST104, the beverage storage container C (for example, the beverage storage container C housed inside the beverage server main body 10) is replaced with a new beverage storage container. The replacement timing is, for example, when the remaining amount of beverage in the beverage storage container C becomes zero (including substantially zero).

In the third embodiment, the wetted part PA including the first pipe 23p that defines the first flow path 23 may be replaced or cleaned in accordance with the replacement timing of the beverage storage container C. The wetted parts PA including the first pipe 23p may be replaced or cleaned, and the wetted parts PA including the second gas pipe 32p′, the beverage pipe 31p and the first pipe 23p may be replaced or washed. .

In the example shown in FIGS. 10 to 12, the liquid-contacting part PA including the first pipe 23p (or the liquid-contacting part PA including the second gas pipe 32p', the beverage pipe 31p, and the first pipe 23p) is used for beverage storage. It is taken out from the beverage server main body 10 together with the container C. After that, the wetted part PA is washed and reused, or the wetted part PA is replaced with a new wetted part.

In the fourth step ST104, first, the lid portion 10b of the beverage server main body 10 is opened. In the example illustrated in FIG. 10 , the lid portion 10b of the beverage server main body 10 is hinged to the base portion 10a of the beverage server main body 10 . Therefore, the lid portion 10b is opened by rotating the lid portion 10b about the hinge axis AX with respect to the base portion 10a.

Next, as shown in FIG. 11, the beverage storage container C and the wetted part PA are taken out integrally from the beverage server main body 10 . Thereafter, as shown in FIG. 12, the beverage storage container C and wetted parts PA may be separated. In addition, in the example shown in FIG. 12, the wetted part PA includes a lid member CP attached to the beverage storage container C. As shown in FIG. The lid member CP has a first through hole h1 for supplying pressurized gas into the beverage storage container C, a second through hole h2 for taking out the beverage from the beverage storage container C, and a gas outlet from the beverage storage container C. A third through hole h3 for supplying the pressurized gas to the supply flow path 32 may be provided. The wetted parts PA removed from the beverage server 1A may be reused after cleaning, or may be replaced with new wetted parts.

In the examples shown in FIGS. 10 to 12, it is possible to remove the entire wetted part PA that contacts the beverage from the beverage server main body 10 and clean or replace it. Therefore, it is easy to maintain the sanitary condition of the beverage server 1A. Further, when the beverage server main body 10 and the liquid-contacting part PA are separate bodies and the beverage server main body 10 does not include liquid-contacting parts, the frequency of cleaning the beverage server main body 10 can be reduced.

It is clear that the present invention is not limited to the above embodiments, and that each embodiment can be appropriately modified or changed within the scope of the technical idea of the present invention. Also, various techniques used in each embodiment can be applied to other embodiments as long as there is no technical contradiction. Furthermore, optional additional configurations in each embodiment can be omitted as appropriate.

For example, the beverage pouring mode, the foam pouring mode, and the foam removing mode described above may be implemented by the controller sending control commands to the first valve V1, the second valve, the pump 40a, and the foam generator 25. good. Alternatively, the opening and closing of the first valve V1 and the second valve may be mechanically performed by operating an operation part (such as an operation lever). In this case, it is preferable that the foam removing mode is automatically executed after the foam pouring mode is executed. For example, between the foam dispensing mode and the foam removing mode, the foam removing mode is automatically executed after the foam dispensing mode without the user of the beverage server actively operating the operation unit. It is preferably configured as follows. With this configuration, since the bubble removal mode is automatically executed, the operation burden on the user can be reduced. Also, the operation of the pump 40a and the foam generating section 25 may be performed by a mechanical switch that switches ON/OFF by operating an operation section (such as an operation lever).

In the second embodiment described above, the example in which the seal member S1 and the check valve V3 are arranged in the gas pipe 32p that defines the gas supply flow path has been described. As shown in FIG. 4, the seal member S1 prevents the beverage from leaking out from between the gas pipe 32p and the first pipe 23p, and the check valve V3 prevents the gas supply from the first flow path 23. To prevent the beverage from flowing back into the flow path 32. - 特許庁However, when the sealing member S1 and the check valve V3 are arranged in the gas pipe 32p that defines the gas supply flow path, when the sealing member S1 is separated from the first pipe 23p (see FIG. 13). , the beverage adhering to the area AR of the seal member S1 on the distal end side of the check valve V3 may adhere to the beverage server main body 10 . In other words, the beverage may adhere to the beverage server main body 10 when the lid portion 10b of the beverage server main body 10 is opened and closed.

Therefore, instead of arranging the seal member S1 and the check valve V3 in the gas pipe 32p that defines the gas supply flow path 32, the seal member S1 and the check valve V3 are arranged in the first pipe 23p. good too. In this case, when the lid portion 10b of the beverage server main body 10 is opened and closed, adhesion of the beverage to the beverage server main body 10 is suppressed.

Further alternatively, as shown in FIG. 14, the seal member S1 may be arranged in the gas pipe 32p defining the gas supply flow path 32, and the check valve V3 may be arranged in the first pipe 23p. Also in this case, when the lid portion 10b of the beverage server main body 10 is opened and closed, adhesion of the beverage to the beverage server main body 10 is suppressed. In addition, in the example shown in FIG. 14, the sealing member S1 is arranged in the gas pipe 32p instead of in the first pipe 23p. Therefore, when the wetted part PA including the first pipe 23p is a replacement part, an increase in the manufacturing cost of the replacement part is suppressed.

Further, in the above-described embodiment, the example of removing bubbles remaining in the first flow path 23 by introducing the pressurized gas into the first flow path 23 has been described. Alternatively, residual bubbles in the first flow path may be removed by introducing unpressurized atmospheric gas into the first flow path 23 . For example, in the example shown in FIG. 15, the gas supply channel 32 that supplies gas to the first channel 23 has an air release hole 40b, and the air release hole 40b functions as the gas supply section (40).

It should be noted that the gas supply channel 32 need not be connected to the pump 40a when the bubble removal process is performed using non-pressurized atmospheric gas. In this case, the “pressurized gas” in the above-described first to third embodiments is read as “non-pressurized atmospheric gas (or “gas”)”, and the gas supply channel 32 is pressurized. The pressurized gas supply unit 40 that supplies gas can be read as the atmosphere opening hole 40 b (or “gas supply unit”) that supplies non-pressurized atmospheric gas to the gas supply channel 32 . Also, in the bubble removal mode shown in FIG. 5B, the pump 40a need not be activated.

(Fourth embodiment)
A method of using the beverage server in the fourth embodiment will be described with reference to FIGS. 16 to 19. FIG.

A schematic perspective view of the valve member 5 is shown on the upper left side of FIG. On the side is a cross-sectional view of the valve member 5 showing the valve in its open state. 18 and 19 are schematic diagrams showing each step of the method of using the beverage server in the fourth embodiment.

In the above-described first to third embodiments, the example of removing the bubbles remaining in the first flow path 23 by introducing the pressurized gas into the first flow path 23 has been described. In a fourth embodiment, bubbles remaining in the first flow path 23 are removed by introducing an unpressurized gas (eg air at atmospheric pressure) into the first flow path 23 . In the fourth embodiment, the points different from the above-described first to third embodiments and modified examples will be mainly described, and the items already described in the first to third embodiments and modified examples will be repeated. The explanation that becomes is omitted. Therefore, even if not explicitly described in the fourth embodiment, it goes without saying that the matters already described in the first to third embodiments and modifications are applicable to the fourth embodiment.

In the example shown in FIG. 16, a gas pipe 32p having an air release hole 40b is attached to the first pipe 23p that defines the first flow path 23. In the example shown in FIG. The air release hole 40b functions as a gas supply section (40). The shape and length of the gas supply channel 32 defined by the gas pipe 32p are arbitrary.

In the example shown in FIG. 16, the gas pipe 32p is provided in the valve member 5. As shown in FIG. In other words, the valve member 5 functions as a member that defines the gas supply channel 32 and also functions as a valve.

In the example shown in FIG. 16, the valve member 5 has a first tubular body 51 and a second tubular body 52 defining the gas supply channel 32 . The first tubular body 51 defines a channel communicating with the first channel 23 (for example, a channel always communicating with the first channel 23). The second tubular body 52 also has a closing portion 521 capable of opening and closing the opening 51 a of the first tubular body 51 .

In the example shown in FIG. 16, the valve member 5 is attached to the first pipe 23p by press-fitting the first tubular body 51 into the first pipe 23p. More specifically, in the example shown in FIG. 16, the first tubular body 51 is attached to the branch portion 23D perpendicular to the longitudinal direction of the first pipe 23p. Note that the method of attaching the valve member 5 to the first pipe 23p is not limited to the example shown in FIG. 16, and is arbitrary.

In the example shown in FIG. 16, the first tubular body 51 defines a vertical hole 51h. The axis of the vertical hole 51h is non-parallel to the longitudinal direction of the first pipe 23p. The axis of the vertical hole 51h is preferably perpendicular to the longitudinal direction of the first pipe 23p. The length of the vertical hole 51h is, for example, 2 cm or less, or 1 cm or less.

In the example shown in FIG. 16, the second tubular body 52 defines a horizontal hole 52h, and the horizontal hole 52h functions as the gas supply channel 32. In the example shown in FIG. The axis of the horizontal hole 52h is non-parallel to the axis of the vertical hole 51h. The axis of the horizontal hole 52h is preferably perpendicular to the axis of the vertical hole 51h. The length of the horizontal hole 52h is, for example, 2 cm or less, or 1 cm or less.

In the example shown in FIG. 16 , the second tubular body 52 has a flange portion 522 that protrudes outward from the outer peripheral surface of the first tubular body 51 . The flange portion 522 is arranged in contact with the branch portion 23D of the first pipe 23p.

As shown in FIG. 17, the second tubular body 52 may be a deformable tube (in other words, a flexible tube). In the example shown in FIG. 17 (upper right view of FIG. 17), the deformable upper wall of the second tubular body 52 is a closing portion 521 (in other words, a closed portion 521) capable of opening and closing the opening 51a of the first tubular body 51. , valve body). Further, in the example shown in FIG. 17, the flange portion 522 of the first tubular body 51 functions as a valve seat portion. A second valve V2 is configured by the valve body and the valve seat portion.

In the example shown in FIG. 17, the upper surface 521u of the closing portion 521 functions as a surface to be pressed by the pressing member. Then, when the pressed surface is pressed by the pressing member, the second valve V2 is closed, and when the pressed surface is released, the second valve V2 is opened.

In the example shown in FIG. 17 (the diagram on the lower right side of FIG. 17), the second tubular body 52 includes a first atmosphere opening hole 40b-1 arranged at the first end of the second tubular body 52, and a second air opening hole 40b-2 arranged at the second end of the second tubular body 52. As shown in FIG. Further, in the example shown in FIG. 17, a T-shaped flow path is formed by the horizontal hole 52h and the vertical hole 51h.

In the example shown in FIG. 17, the valve member 5 is made of resin or rubber. Moreover, the valve member 5 is formed by integral molding. When the valve member 5 is formed by integral molding, the manufacturing cost of the valve member 5 is reduced. Further, when the valve member 5 is made of resin or rubber, in other words, when the valve member 5 does not include metal parts, the valve member 5 is connected to the first pipe 23p (for example, the first pipe made of resin). It can be discarded together with the pipe 23p). In other words, there is no need to dispose of the valve member 5 and the first pipe 23p separately.

(How to use the beverage server)
Next, an example of how to use the beverage server in the fourth embodiment will be described with reference to FIGS. 18 and 19. FIG. In the first step ST1, the beverage B is poured out from the pouring port 21 of the beverage pouring part 20. As shown in FIG. FIG. 18(a) shows a state in which the first step ST1 (beverage dispensing step) is being executed. In the first step ST1, the first valve V1 arranged in the beverage pipe 31p is opened so that the beverage is supplied from the beverage pipe 31p (beverage supply channel 31) to the first pipe 23p (first channel 23). is supplied. Then, the beverage supplied to the first channel 23 is poured out from the outlet 21 .

In the second step ST2, the foam F is poured out from the pouring port 21 of the beverage pouring part 20. As shown in FIG. FIG. 18(b) shows a state during execution of the second step ST2 (bubble pouring step). In the second step ST2, by opening the first valve V1 arranged in the beverage pipe 31p, the beverage is supplied from the beverage pipe 31p (beverage supply channel 31) to the first pipe 23p (first channel 23). is supplied. Also, the beverage supplied to the first pipe 23p becomes foam due to the action of the foam generator 25 (for example, the ultrasonic transducer 25a). Then, the foam F in the first pipe 23p is poured out from the outlet 21. As shown in FIG.

After execution of the second step ST<b>2 , bubbles remain in the first flow path 23 of the beverage extraction part 20 . FIG. 19(a) shows the state after execution of the second step ST2 (bubble pouring step).

In the third step ST3, the foam F remaining in the first channel 23 of the beverage extraction part 20 is removed. FIG. 19(b) shows the state during execution of the third step ST3 (bubble removal step). As shown in FIG. 19(b), the bubbles F are removed from the first channel 23 by executing the third step ST3. It should be noted that most of the bubbles remaining in the first channel 23 are preferably removed in the third step ST3.

In the example shown in FIG. 19B, the third step ST3 is performed by introducing air (atmospheric pressure air) into the first flow path 23 . More specifically, in the third step ST3, the state of the second valve V2 is changed from the closed state to the open state. As a result, air is introduced into the first flow path 23 through the atmosphere release hole 40b of the valve member 5 (or the gas pipe 32p). The bubbles F remaining in the first flow path 23 are removed from the first flow path 23 by the air introduced into the first flow path 23 .

By executing the first step ST1 to the third step ST3, the beverage and foam are poured from the beverage server (more specifically, the outlet 21) into a drink container such as a glass or mug. Execution of the first step ST1 to the third step ST3 corresponds to execution of one cycle (for example, the first cycle) of how to use the beverage server. In the first cycle, one beverage container is dispensed with beverage and foam.

In the fourth step ST4, the beverage B is poured out from the pouring port 21 of the beverage pouring part 20. As shown in FIG. 4th step ST4 is performed after 3rd step ST3 (bubble removal process). Since the foam remaining in the beverage extraction part 20 is removed before the execution of the fourth step ST4, mixing of the foam into the beverage is suppressed during the execution of the fourth step ST4. A fourth step ST4, a fifth step ST5, and a sixth step ST6 are processes similar to the first step ST1, the second step ST2, and the third step ST3, respectively. Execution of the fourth step ST4 to sixth step ST6 corresponds to execution of one cycle (for example, the second cycle) of the method of using the beverage server. In the second cycle, another beverage container is dispensed with beverage and foam.

In the usage method of the beverage server in the fourth embodiment, a cycle consisting of first step ST1 to third step ST3 is repeatedly executed. It should be noted that between cycles the beverage container receiving the beverage and foam is different.

The usage method of the beverage server in the fourth embodiment has the same effects as the usage method of the beverage server in the first embodiment. Further, in the fourth embodiment, it is not necessary to supply the pressurized gas to the first flow path 23 in the bubble removing step (third step ST3). Therefore, in the fourth embodiment, it is possible to employ a simple gas pipe 32p instead of the pipe for supplying the pressurized gas illustrated in the first embodiment.

As shown in Figures 18 and 19, the beverage server in the fourth embodiment may comprise a pump 40a. In this case, the above-described beverage pouring step (in other words, the first step ST1 or the fourth step ST4) increases the pressure in the beverage storage container C using the pump 40a such as an electric pump. It may involve pushing the beverage from the beverage storage container C into the beverage dispensing portion 20 .

In the example shown in FIG. 20, the beverage storage container C is arranged inside the beverage server main body 10 . The beverage server main body 10 may include a cooling mechanism for cooling the beverage in the beverage storage container C. Alternatively, a cooling pipe may be arranged in the beverage server main body 10, and the beverage may be supplied to the cooling pipe from a beverage storage container C outside the beverage server main body. Therefore, the beverage server main body 10 may be a housing that can accommodate the beverage storage container C, or may be a housing that incorporates a cooling pipe.

In the example illustrated in FIG. 20 , the beverage extraction unit 20 includes a first flow path 23 , a foam generation unit 25 that generates foam in the first flow path 23 , and a beverage flow path that supplies the beverage to the first flow path 23 . It includes a supply channel 31 and a pump 40a for supplying beverage to the beverage supply channel 31 .

In the example shown in FIG. 20, when the beverage supply channel 31 and the first channel 23 are in communication (in other words, when the first valve V1 is open), the first channel 23 is supplied with the beverage. Beverage is supplied from the channel 31 . In the example shown in FIG. 20, when the gas supply channel 32 and the first channel 23 are in communication (in other words, when the second valve V2 is open), the first channel 23 has Air is supplied from the gas supply channel 32 . As a result, the bubbles remaining in the first channel 23 are discharged from the outlet 21 .

The bubble generator 25 generates bubbles inside the first flow path 23 . In the example shown in FIG. 20, the bubble generator 25 includes an ultrasonic transducer 25a. Alternatively, the foam generator 25 may be a foam generator that generates foam by a mechanism other than ultrasonic vibration.

In the example illustrated in FIG. 20, the pump 40a (for example, an electric pump) supplies pressurized gas to the pressurizing chamber CB via the first gas pipe 33p.

More specifically, the first end E6 of the first gas pipe 33p that supplies gas to the pressurizing chamber CB is connected to the pump 40a, and the second end E7 of the first gas pipe 33p is connected to the pressurizing chamber CB. communicate. In addition, in the example shown in FIG. 20, a sealing member S2 that adheres to the lid member CP of the beverage storage container C is arranged at the second end E7 of the first gas pipe 33p.

In the example illustrated in FIG. 20 , the beverage server 1C includes a first valve V1 that opens and closes the beverage supply channel 31 and a second valve V2 that opens and closes the gas supply channel 32 .

As a method for opening and closing the beverage supply channel 31 by the first valve V1, any known method can be adopted. In the example shown in FIG. 20, the first valve V1 is a valve capable of crushing the beverage pipe 31p that defines the beverage supply channel 31. In the example shown in FIG. Further, in the example shown in FIG. 20, the first valve V1 is a mechanical valve that is opened and closed by operating the operating portion 6. As shown in FIG.

As a method for opening and closing the gas supply channel 32 by the second valve V2, any known method can be adopted. In the example shown in FIG. 20, the second valve V2 is a valve capable of closing the gas supply channel 32 by crushing the gas pipe 32p. Further, in the example shown in FIG. 20, the second valve V2 is a valve that is opened and closed by operating the operation unit 6. In the example shown in FIG. The valve member 5 described in the fourth embodiment may be employed as the second valve V2 and the gas pipe 32p.

In the example shown in FIG. 20, the beverage dispensing unit 20 has a beverage or foam supply mode in which the first valve V1 is opened, the second valve V2 is closed, and the pump 40a is driven; A foam removal mode in which the second valve V2 is opened and the first valve V1 is closed can be executed.

It is preferable to be able to execute a foam supply mode in which it is in a driven state or in a non-driven state.

In the example shown in FIG. 20, when the operating portion 6 is changed from the neutral position to the beverage dispensing position (in other words, when the operating portion 6 is operated in the first operating direction), the beverage is dispensed. becomes. Further, when the operating portion 6 is changed from the neutral position to the foam pouring position (in other words, when the operating portion 6 is operated in the second operating direction), a foam pouring state is entered in which foam is poured. Further, when the operating portion 6 is returned from the foam pouring position to the neutral position, the gas (more specifically, air at atmospheric pressure) is supplied to the first flow path 23 and the foam remaining in the first flow path 23 is removed. is removed. In the example shown in FIG. 20, when the operating portion 6 is returned to the neutral position, the atmosphere release hole 40b is automatically communicated with the first flow path 23. In the example shown in FIG. Therefore, it is not necessary to perform complicated operations to perform the foam removal process.

(How to use the beverage server in the fifth embodiment)
A method of using the beverage server 1C in the fifth embodiment will be described with reference to FIGS. 20 to 22. FIG. 20 to 22 are diagrams schematically showing one step of how to use the beverage server 1C.

In the first step ST101 (beverage pouring step), the beverage is poured from the pouring port 21 of the beverage pouring part 20 .

In the first step ST101, the beverage pouring mode is executed according to the operation of the operation section 6 (more specifically, the operation section 6 is operated in the first operation direction). In the beverage dispensing mode, the first valve V1 is opened, the second valve V2 is closed, the foam generator 25 (more specifically, the ultrasonic transducer 25a) is deactivated, Also, the pump 40a is activated.

In the beverage dispensing mode, the pump 40a supplies pressurized gas to the pressurized chamber CB via the first gas pipe 33p. In the example shown in FIG. 20, the pressurized chamber CB is a gas chamber within the beverage reservoir C. In the example shown in FIG. Alternatively, the pressurized gas may be supplied into the pressurized chamber containing the entire beverage storage container C with the lid open.

When pressurized gas is supplied into the pressurization chamber, the pressure of the pressurized gas pushes the beverage out of the beverage storage container C. As shown in FIG. The extruded beverage passes through the beverage supply channel 31 and the first channel 23 and is poured out from the outlet 21 .

In the second step ST102 (foam pouring step), foam is poured from the pouring port 21 of the beverage pouring part 20 .

In the second step ST102, the foam pouring mode is executed according to the operation of the operation section 6 (more specifically, the operation section 6 is operated in the second operation direction). In the foam pouring mode, the first valve V1 is opened, the second valve V2 is closed, the foam generator 25 (more specifically, the ultrasonic transducer 25a) is activated, and , the pump 40a is activated or deactivated.

In the foam extraction mode, the pump 40a supplies pressurized gas to the pressurized chamber CB through the first gas pipe 33p.

When pressurized gas is supplied into the pressurized chamber CB, the beverage is pushed out of the beverage storage container C by the pressure of the pressurized gas. Alternatively, the residual pressure in the pressurization chamber CB may be used to force the beverage out of the beverage storage container C. In this case, there is no need to operate the pump 40a. Beverage extruded from the beverage storage container C flows through the beverage supply channel 31 into the first channel 23 . In the bubble ejection mode, the bubble generator 25 (more specifically, the ultrasonic transducer 25 a ) is in an operating state, so bubbles are generated in the first flow path 23 by the bubble generator 25 . The foam generated in the first channel 23 passes through the first channel 23 and is discharged from the outlet 21 .

In the third step ST103 (foam removing step), the foam remaining in the first flow path 23 of the beverage dispensing portion 20 is removed.

In the third step ST103, the bubble removal mode is executed in accordance with the operation of the operation section 6 (more specifically, the operation of returning the operation section 6 to the neutral state). In the bubble removal mode, the second valve V2 is opened, the first valve V1 is closed, and the bubble generator 25 (more specifically, the ultrasonic transducer 25a) is activated or deactivated. and the pump 40a is activated or deactivated.

In the bubble removal mode, air is introduced into the first flow path 23 through the air release hole 40b of the valve member 5 (or the gas pipe 32p). The air introduced into the first flow path 23 causes the foam F remaining in the first flow path 23 to be discharged from the spout 21 .

A cycle consisting of the above-described first step ST101 to third step ST103 is repeatedly executed, and the beverage container for receiving the beverage or foam to be poured out from the outlet 21 is replaced between cycles.

In the fourth step ST104, the beverage storage container C (for example, the beverage storage container C housed inside the beverage server main body 10) is replaced with a new beverage storage container. The replacement timing is, for example, when the remaining amount of beverage in the beverage storage container C becomes zero (including substantially zero).

In the fifth embodiment, the wetted part PA including the first pipe 23p that defines the first flow path 23 may be replaced or cleaned in accordance with the replacement timing of the beverage storage container C. The wetted part PA including the first pipe 23p may be replaced or cleaned.

In the example shown in FIGS. 21 and 22, the liquid-contacting part PA including the first pipe 23p (or the liquid-contacting part PA including the beverage pipe 31p and the first pipe 23p) is connected to the beverage server main body 10 together with the beverage storage container C. taken out from After that, the wetted part PA is washed and reused, or the wetted part PA is replaced with a new wetted part.

As shown in FIG. 21, in the fourth step ST104, first, the lid portion 10b of the beverage server main body 10 is opened.

Next, as shown in FIG. 22 , the beverage storage container C and the wetted part PA are integrally taken out from the beverage server main body 10 .

The fifth embodiment has the same effect as the second embodiment. Further, in the fifth embodiment, it is not necessary to supply the pressurized gas to the first flow path 23 in the bubble removing step (third step ST103). Therefore, in the fifth embodiment, a simple gas pipe 32p can be employed instead of the pipe (32p-1) for supplying the pressurized gas illustrated in the second embodiment. .

Further, in the fifth embodiment, the gas pipe 32p is attached to the first pipe 23p that defines the first flow path 23. As shown in FIG. Then, when replacing the beverage storage container C, it is possible to discard the gas pipe 32p together with the first pipe 23p. Further, in the fifth embodiment, all wetted parts PA can be removed integrally from the beverage server main body 10 . Therefore, it is possible to easily replace the wetted parts including the beverage storage container C. As shown in FIG.

Furthermore, in the fifth embodiment the valve member 5 defining the second valve V2 is a disposable part. Therefore, there is no need to worry about failure of the second valve V2.

(Mechanism for transmitting the force acting on the operation part 6 to the first valve and/or the second valve)
An example of a mechanism for transmitting force acting on the operating portion 6 to the first valve V1 and/or the second valve V2 will be described with reference to FIGS. 23 and 24. FIG. 23 and 24 are schematic cross-sectional views schematically showing part of the beverage server.

First, the first operating force transmission mechanism for transmitting the force acting on the operating portion 6 to the first valve V1 will be described. The first operating force transmission mechanism includes an operating portion 6 , a support portion 13 that supports the operating portion 6 so as to be able to swing about the swing axis AX<b>2 , and a first pressing portion 61 . The first operating force transmission mechanism may include a biasing member that biases the operating portion 6 toward the neutral position. The biasing member is, for example, a spring (for example, a torsion coil spring) arranged between the operating portion 6 and the support portion 13 .

In the example shown in FIGS. 23 and 24, the support portion 13 that rockably supports the operation portion 6 is provided on the beverage server main body, more specifically on the lid portion 10b. Also, the first pressing member 61 is provided at the distal end of the operating portion 6 .

As shown in FIGS. 23(a) and 24(a), the beverage pipe 31p is crushed by the first pressing portion 61 when the operation portion 6 is in the neutral position. More specifically, when the operating portion 6 is at the neutral position, the beverage pipe 31p is configured to be the first pressing portion 61 and the receiving portion 62 arranged on the beverage server main body (more specifically, the base portion 10a). crushed by being sandwiched between In the example shown in FIGS. 23(a) and 24(a), the first pressing portion 61 and the receiving portion 62 constitute a pinch valve, and the pinch valve functions as the first valve V1.

When the operating portion 6 is operated in the first operating direction, the first pressing portion 61 moves away from the receiving portion 62 as shown in FIGS. 23(b) and 23(c). More specifically, when the operating portion 6 is operated in the first operating direction, the first pressing portion 61 moves backward and upward with respect to the receiving portion 62 . Thus, the crushed state of the beverage pipe 31p is released. As a result, the beverage supply channel 31 is opened and the first valve V1 is opened.

When the operating portion 6 is operated in the second operating direction, the first pressing portion 61 moves away from the receiving portion 62 as shown in FIGS. 24(b) and 24(c). More specifically, when the operating portion 6 is operated in the second operating direction, the first pressing portion 61 moves forward and upward with respect to the receiving portion 62 . Thus, the crushed state of the beverage pipe 31p is released. As a result, the beverage supply channel 31 is opened and the first valve V1 is opened.

Next, the second operating force transmission mechanism for transmitting the force acting on the operating portion 6 to the second valve V2 will be described. The second operating force transmission mechanism includes the operation portion 6, the support portion 13 that supports the operation portion 6 so as to be able to swing about the swing axis AX2, the pressing member 72 (in other words, the second pressing portion), and an operation force transmission member 70 that transmits force acting on the operation portion 6 to the pressing member 72 . The second operating force transmission mechanism includes a biasing member 73 that biases the pressing member 72 away from the closing portion 521 (in other words, biases the pressing member 72 upward). may be

As shown in FIGS. 23(a) and 24(a), the second valve V2 is in the open state when the operating portion 6 is in the neutral position. In other words, the pressing member 72 does not press the closing portion 521 of the valve member 5 when the operating portion 6 is in the neutral position.

As shown in FIG. 23( b ), when the operating portion 6 is operated in the first operating direction, the first pressing piece 63 a of the operating portion 6 presses the operating force transmission member 70 . The operating force transmission member 70 pressed by the operating portion 6 presses the pressing member 72 . Also, the pressing member 72 pressed by the operating force transmission member 70 presses the closing portion 521 of the valve member 5 . Thus, the second valve V2 is closed as shown in FIG. 23(b).

In the example shown in FIG. 23(b), since the first valve V1 is in the closed state, it is necessary to further operate the operating portion 6 in the first operating direction in order to open the first valve V1. When the operation portion 6 is further operated in the first operation direction, the first valve V1 is opened as shown in FIG. 23(c).

On the other hand, in the example shown in FIG. 23(b), the pressing member 72 is at the lower limit position. Therefore, when the operation portion 6 is further operated in the first operation direction from the state shown in FIG. 23(b), the pressing member 72 cannot move. In the example shown in FIG. 23(b), the operating force transmission member 70 includes an elastically deformable portion 71 (for example, leaf spring). Therefore, the operation portion 6 can be operated in the first operation direction while the pressing member 72 is not moving. In other words, the operating force acting on the operating portion 6 can be absorbed by the elastic deformation of the elastically deformable portion 71 .

In the example shown in FIG. 23, when the operating portion 6 is operated in the first operating direction, the second valve V2 is closed as shown in FIG. 23(b), and then, as shown in FIG. , the first valve V1 is opened. Therefore, the first valve V1 and the second valve V2 are not opened at the same time, and the beverage passing through the first valve V1 does not leak through the second valve V2.

Further, in the example shown in FIG. 23, when the operating portion 6 is released, the operating portion 6 is moved by the biasing force of a biasing member (for example, a torsion coil spring) that biases the operating portion 6 toward the neutral position. , automatically returns to the neutral position. When the operating portion 6 returns to the neutral position, the first valve V1 is closed and the second valve V2 is opened.

Further, when the operating portion 6 returns to the neutral position, the pressing member 72 moves upward (in other words, away from the closing portion 521) due to the biasing force of the biasing member 73. As shown in FIG. In the example shown in FIG. 23, the biasing member 73 includes a guide portion 12 (more specifically, a guide portion 12 provided in the lid portion 10b) that slidably guides the pressing member 72; 72 (more specifically, the upper end of the pressing member 72).

As shown in FIG. 24B, when the operating portion 6 is operated in the second operating direction, the second pressing piece 63b of the operating portion 6 presses the operating force transmission member 70. As shown in FIG. The operating force transmission member 70 pressed by the operating portion 6 presses the pressing member 72 . Also, the pressing member 72 pressed by the operating force transmission member 70 presses the closing portion 521 of the valve member 5 . Thus, the second valve V2 is closed as shown in FIG. 24(b).

In the example shown in FIG. 24(b), since the first valve V1 is in the closed state, it is necessary to further operate the operating section 6 in the second operating direction in order to open the first valve V1. When the operating portion 6 is further operated in the second operating direction, the first valve V1 is opened as shown in FIG. 24(c).

On the other hand, in the example shown in FIG. 24(b), the pressing member 72 is at the lower limit position. Therefore, when the operation portion 6 is further operated in the second operation direction from the state shown in FIG. 24(b), the pressing member 72 cannot move. In the example shown in FIG. 24(b), the operating force transmission member 70 includes an elastically deformable portion 71 (for example, leaf spring). Therefore, the operation portion 6 can be operated in the second operation direction while the pressing member 72 is not moving. In other words, the operating force acting on the operating portion 6 can be absorbed by the elastic deformation of the elastically deformable portion 71 .

In the example shown in FIG. 24, when the operating portion 6 is operated in the second operating direction, the second valve V2 is closed as shown in FIG. , the first valve V1 is opened. Therefore, the first valve V1 and the second valve V2 are not opened at the same time, and the beverage passing through the first valve V1 does not leak through the second valve V2.

Further, in the example shown in FIG. 24, when the operating portion 6 is released, the operating portion 6 is moved by the biasing force of a biasing member (for example, a torsion coil spring) that biases the operating portion 6 toward the neutral position. , automatically returns to the neutral position. When the operating portion 6 returns to the neutral position, the first valve V1 is closed and the second valve V2 is opened. When the second valve V2 is opened, air is introduced into the first flow path 23 via the second valve V2, and bubbles in the first flow path 23 are removed.

In the example shown in FIG. 23, when the operating portion 6 is operated in the first operating direction, the beverage pouring mode is executed. For example, when the operating portion 6 is operated in the first operating direction, the second valve V2 is closed, the first valve V1 is opened, and the pump 40a is operated. Further, in the example shown in FIG. 24, when the operating portion 6 is operated in the second operating direction, the foam pouring mode is executed. For example, when the operating portion 6 is operated in the second operating direction, the second valve V2 is closed, the first valve V1 is opened, and the ultrasonic transducer 25a is activated. At this time, the pump 40a may or may not be operated.

In addition, in the foam dispensing mode, if an excessive amount of beverage is supplied to the first flow path 23, there is a risk that the generation of foam in the first flow path 23 will be insufficient. Therefore, it is preferable that the opening degree of the first valve V1 remains half open even when the operating portion 6 is operated to the maximum extent in the second operating direction. In other words, the maximum opening of the first valve V1 in the foam pouring mode is preferably set to be smaller than the maximum opening of the first valve V1 in the beverage pouring mode. The maximum degree of opening of the first valve V1 in the foam pouring mode can be set by, for example, providing a stopper 74 on the lid portion 10b. In the example shown in FIG. 25, the stopper 74 is provided on the lid portion 10b. The stopper 74 is, for example, an edge that defines the operating portion insertion hole 6h.

With reference to FIG. 25, an example of the execution procedure of the foam pouring process and the foam removing process will be described. FIG. 25 is a diagram for explaining an example of the execution procedure of the foam pouring process and the foam removing process.

In the foam pouring step, the operating portion 6 is operated in the second operating direction. When the operation portion 6 is operated in the second operation direction, the operation portion 6 swings around the swing axis AX2. When the operating portion 6 swings around the swing axis AX2, the second pressing piece 63b of the operating portion 6 presses the operating force transmission member . When the operating force transmitting member 70 is pressed, the operating force transmitting member 70 swings around the second swing axis AX3, and the elastically deformable portion 71 of the operating force transmitting member 70 presses the pressing member 72. As shown in FIG. The pressing member 72 pressed by the elastically deformable portion 71 presses the second valve V2 to close the second valve V2.

When the operation portion 6 is further operated in the second operation direction, the operation portion 6 swings around the swing axis AX2 while the pressing member 72 is stopped from moving. As a result, the first pressing portion 61 of the operating portion 6 moves away from the receiving portion 62, and the first valve V1 is in a half-open state. Since the movement of the operating portion 6 in the second operating direction is restricted by the stopper 74, the first valve V1 is prevented from being fully opened.

Further, the pump 40a is operated in response to the operating portion 6 being operated in the second operating direction. Therefore, the beverage is supplied from the beverage supply channel 31 to the first channel 23 via the half-opened first valve V1. In addition, when the beverage is supplied to the beverage supply channel 31 by the residual pressure in the pressurization chamber CB, the pump 40a does not have to be operated.

The ultrasonic transducer 25a may be actuated in response to the operating portion 6 being operated in the second operating direction. In this case, foam is produced from the beverage supplied to the first channel 23 . The generated foam is poured out from the outlet 21 .

In the foam removing process, the operating portion 6 is returned from the foam pouring position to the neutral position. For example, when the operating portion 6 is released, the operating portion 6 returns to the neutral position due to the biasing force of the biasing member that biases the operating portion 6 toward the neutral position. When the operating portion 6 returns from the foam pouring position to the neutral position, first the first valve V1 is closed and then the second valve V2 is opened. When the second valve V2 is opened, air is introduced into the first flow path 23 through the atmosphere opening hole 40b and the gas supply flow path 32. As shown in FIG. As a result, the bubbles remaining in the first channel 23 are discharged from the outlet 21 . Bubbles are thus removed from the first flow path 23 .
