The dispensing head 50 is configured to switch the communication state between the first fluid inlet 516 and the second fluid inlet 517 and the fluid outlet 521 . Specifically, the dispensing head 50 switches the communication state of the plunger 52 within the housing 51 by sliding.

The plunger 52 directly communicates the first fluid inlet 516 and the fluid outlet 521 and blocks the second fluid inlet 517 from the inside of the beverage container 20 and the fluid outlet 521 In position 1, the first fluid inlet 516 is blocked from the interior of the beverage receiving container 20 and the fluid outlet 521 and the second fluid inlet 517 and the fluid outlet 521 are connected to the beverage receiving container 20 between the second positions communicating through the interior of the In the present embodiment, the upper position of the plunger 52 corresponds to the first position, and the lower position of the plunger 52 corresponds to the second position.

By the way, after the supply of the drink by the drink supply system 1 is complete|finished, a drink remains in the flow path of a drink. The remaining beverage causes deterioration of the beverage, propagation of microorganisms, and the like. For this reason, in order to prevent the fall of the taste of a drink, the drink supply system 1 must be wash|cleaned regularly.

In the present embodiment, when cleaning the beverage supply system 1 , the user sets the position of the operation unit 53 to the upward position and opens the main cock of the water supply source 100 . As a result, the plunger 52 is positioned in the upward position, and water is supplied to the first fluid inlet 516 . Fig. 2 shows the dispensing head 50 when the plunger 52 is positioned at the upper position.

As shown in FIG. 2, when the plunger 52 is located in an upper position, the 1st sealing member 301 is the 1st recessed part 522 and the 2nd recessed part in a vertical direction (axial direction). 523) is located above it. As a result, the first sealing member 301 contacts the outer surface of the plunger 52 to seal the space between the housing 51 and the plunger 52 . Accordingly, it is possible to prevent the water supplied to the first fluid inlet 516 from flowing upward through the space between the housing 51 and the plunger 52 .

On the other hand, when the plunger 52 is located in the upper position, the positions of the first concave portion 522 and the second sealing member 302 in the vertical direction coincide, and the second sealing member 302 is a first concave It faces the portion 522 .

As a result, a space is created between the spindle 542 of the on-off valve 54 and the plunger 52, and no force opposing the biasing force of the spring 544 of the on-off valve 54 is generated. For this reason, the on-off valve 54 closes the second fluid inlet 517 , so that the gas supplied to the second fluid inlet 517 cannot flow into the space between the housing 51 and the plunger 52 . .

Further, when the plunger 52 is positioned in the upward position, the fourth sealing member 304 disposed on the outer surface of the plunger 52 does not contact the gas flow path closing portion 23 . For this reason, the 5th sealing member 305 arrange|positioned at the upper end of the gas flow path closing part 23 contacts the valve case 22 by the biasing force of the 1st spring 401, and the valve case 22 and gas Seal the space between the flow path closures 23 . Accordingly, water flowing into the valve case 22 through the space between the housing 51 and the plunger 52 can be prevented from flowing between the valve case 22 and the gas flow path closing part 23 .

Further, when the plunger 52 is positioned in the upward position, the lower end of the plunger 52 does not contact the beverage passage closing portion 24 . For this reason, the beverage flow path closing part 24 comes into contact with the sixth sealing member 306 by the urging force of the second spring 402 , and the sixth sealing member 306 is connected to the gas flow path closing part 23 and 23 . Seals the space between the beverage flow path closures 24 . Accordingly, it is possible to prevent water flowing into the valve case 22 through the space between the housing 51 and the plunger 52 from flowing between the gas flow path closing part 23 and the beverage flow path closing part 24 . .

Water flowing into the valve case 22 flows through the space between the gas flow path closing part 23 and the plunger 52 and the beverage flow path closing part 24 and the plunger 52 into the fluid outlet 521. is brought in Accordingly, when the plunger 52 is in the upward position, the first fluid inlet 516 is in direct communication with the fluid outlet 521 , and the second fluid inlet 517 is in direct communication with the interior of the beverage receiving container 20 and the fluid. It is blocked from the outlet 521 . In this state, when the tap 32 is opened, the water supplied from the water supply source 100 flows through the flow path of the beverage, that is, the dispense head 50, the beverage transfer path 70 and the beverage dispenser 30 (beverage introduction tube ( 31 ) and tab 32 ) are cleaned and discharged from the tab 32 . Water discharged from the tap 32 is accommodated in a drain container 200 installed in advance by a user.

In addition, even when the beverage accommodated in the beverage container 20 is depleted and the beverage container 20 is replaced with a new beverage container, the position of the operation unit 53 is set to the upper position by the user. Thereby, gas leakage at the time of replacing|exchanging the beverage container 20 can be prevented. In addition, when replacing the beverage container 20 , the main cock of the water supply source 100 is placed closed.

On the other hand, when the beverage in the beverage container 20 is supplied to the beverage transfer path 70 by gas, that is, when the beverage is supplied from the beverage dispenser 30, the position of the operation unit 53 is set to the downward position by the user. do. As a result, the plunger 52 is located in the downward position. 4 is a partial cross-sectional view of the dispense head 50 and the spear valve 21 when the plunger 52 is in the downward position.

As shown in FIG. 4, when the plunger 52 is located in a downward position, the 1st sealing member 301 is a vertical direction. WHEREIN: Above the 1st recessed part 522 and the 2nd recessed part 523. is located in As a result, the first sealing member 301 contacts the outer surface of the plunger 52 to seal the space between the housing 51 and the plunger 52 . Accordingly, even if water is supplied to the first fluid inlet 516 , it is possible to prevent water from flowing upward through the space between the housing 51 and the plunger 52 . Further, the first sealing member 301 is in contact with the outer surface of the plunger 52 irrespective of the sliding position of the plunger 52 .

Moreover, when the plunger 52 is located in a downward position, the 2nd sealing member 302 is located above the 1st recessed part 522 and the 2nd recessed part 523 in a vertical direction. As a result, the second sealing member 302 contacts the outer surface of the plunger 52 to seal the space between the housing 51 and the plunger 52 . Accordingly, even if water is supplied to the first fluid inlet 516 , it is possible to prevent water from flowing into the spear valve 21 through the space between the housing 51 and the plunger 52 .

Further, when the plunger 52 moves from the upper position to the lower position, the spindle 542 of the on-off valve 54 is pressed by the inclined surface of the second concave portion 523 . As a result, the spindle 542 moves against the biasing force of the spring 544 , and the on-off valve 54 opens the second fluid inlet 517 . The valve open state of the on-off valve 54 is maintained by the outer surface of the plunger 52 pressing the spindle 542 . Further, the movement of the fluid upward from the second fluid inlet 517 is prevented by the second sealing member 302 . For this reason, the gas supplied to the 2nd fluid inlet port 517 passes through the on-off valve 54 , and flows into the inside of the spear valve 21 through the space between the housing 51 and the plunger 52 .

Further, when the plunger 52 is moved from the upward position to the downward position, the lower end of the plunger 52 presses the beverage passage closing portion 24, and thereafter, a fourth sealing member disposed on the outer surface of the plunger 52 ( 304 presses the gas flow path closure 23 . As a result, the beverage passage closing portion 24 moves against the biasing force of the second spring 402 , thereby creating a space between the sixth sealing member 306 and the beverage passage closing portion 24 . Thereafter, the gas flow path closing portion 23 moves against the biasing force of the first spring 401 , thereby creating a space between the fifth sealing member 305 and the valve case 22 .

Accordingly, the gas flowing into the valve case 22 flows into the beverage container 20 through between the valve case 22 and the gas flow path closing part 23 . As a result, the liquid level of the beverage is pushed down by the gas, and the beverage rises through between the gas flow path closing part 23 and the beverage flow path closing part 24 . The rising beverage flows into the fluid outlet 521 through the through hole 527 formed at the lower end of the plunger 52 .

Accordingly, when the plunger 52 is positioned in the downward position, the first fluid inlet 516 is blocked from the interior of the beverage containing container 20 and the fluid outlet 521 , and the second fluid inlet 517 is configured to receive the beverage. It communicates with the fluid outlet 521 through the interior of the vessel 20 . When the tab 32 is opened in this state, the beverage supplied from the beverage container 20 by gas is poured out from the tab 32 through the beverage transfer path 70 .

As described above, the user sets the position of the operation unit 53 to the upward position when cleaning the beverage supply system 1 . However, there is a risk that the user forgets to switch the operation unit 53 and water is supplied to the dispensing head 50 from the water supply source 100 when the operation unit 53 is positioned at the lower position. Also in this case, in the present embodiment, the inflow of water into the inside of the valve case 22 is prevented by the plunger 52 and the second sealing member 302 . Therefore, it is possible to prevent mixing of the washing water into the beverage in the beverage container 20 during cleaning of the beverage supply system 1 without detecting the position of the operation unit 53 .

In addition, in this embodiment, the on-off valve 54 is arrange|positioned at the 2nd fluid inlet port 517. As shown in FIG. Thereby, the pressure loss at the time of water passing through the on-off valve 54 can be avoided, and by extension, the fall of the washing|cleaning power of water can be avoided.

The user sets the positions of the operation units 53 of the two dispensing heads 50 to the upward position when cleaning the two flow paths of the beverage at the same time, and opens the main cock of the water supply source 100 . Then, when the tabs 32 of the two beverage dispensers 30 are opened, the two flow passages of the beverage are washed with water.

However, there exists a possibility that a user may forget to switch the at least one operation part 53. As shown in FIG. Even in this case, mixing of water into the inside of the beverage container 20 is prevented by the above-described configuration of the dispensing head 50 . In addition, when the user sets the position of the operation unit 53 of one dispensing head 50 to the upper position and sets the position of the operation unit 53 of the other dispensing head 50 to the downward position, one Water is supplied to the beverage transport path 70 of the, and beverage is supplied to the beverage transport path 70 of the other side.

The gas check valve 64 is disposed in the second gas supply path 62 , and prevents a reverse flow of gas (flow to the gas supply source 10 ). In this embodiment, the gas check valve 64 is arrange|positioned in the 2nd gas supply path 62 downstream from the gas on-off valve 63 .

The water on-off valve 91 is electrically connected to the control device 80 , and the control device 80 controls the water on-off valve 91 . The water on/off valve 91 is, for example, a solenoid valve. The water on/off valve 91 is configured to close the water supply path 90 when de-energized and to open the water supply path 90 when energized.

The water check valve 92 is disposed in the water supply path 90 , and prevents a reverse flow of water (flow to the water supply source 100 ). In the present embodiment, the water check valve 92 is disposed in the water supply path 90 downstream of the water on-off valve 91 . The water supply path 90 and the second gas supply path 62 are integrated into one shared flow path on the downstream side of the gas check valve 64 and the water check valve 92 .

The flow rate sensor 44 is disposed in the water supply path 90 , and detects a flow rate of water flowing through the water supply path 90 .

In addition, the flow rate sensor 44 may be arrange|positioned in the water supply path 90 downstream of the water on-off valve 91 and the water check valve 92.

The warning device 45 outputs a warning. For example, the warning device 45 is configured as a sound emitting part such as a piezoelectric sound emitting part, and outputs a warning sound as a warning. The warning device 45 is electrically connected to the control device 80 , and the control device 80 controls the warning device 45 .

Conventionally, in washing|cleaning of the beverage supply system 1b, it was thought that the washing|cleaning power will become high by supplying a large amount of water at once. On the other hand, as a result of earnest examination, the inventor of this application discovered that the washing|cleaning power became high by making the linear velocity of water fast and raising the energy of water. In order to increase the linear speed of water, it is necessary to reduce the amount of water supplied at one time. However, when the amount of water is small, water cannot flow in the beverage transfer path 70 due to resistance in the beverage transfer path 70 .

Therefore, in this embodiment, the control device 80 controls the water on-off valve 91 and the gas on-off valve 63 so that water and gas are alternately supplied to the beverage transfer path 70 . Specifically, the control device 80 closes the gas opening/closing valve 63 and opening the water opening/closing valve 91 so that a reference amount of water is supplied from the water supply path 90 to the beverage transport path 70 . and water shot control in which the gas on-off valve 63 is opened only for a predetermined period of time and the water on-off valve 91 is closed alternately repeated.

In the water shot control, water and gas are intermittently supplied to the beverage transfer path 70, and so-called water shot cleaning is performed. At this time, in order for the gas to function to extrude water, a small amount of water may flow in the beverage transfer path 70 . Therefore, the linear velocity of water can be made fast, and the flow path of the beverage of the beverage supply system 1b can be efficiently cleaned with high cleaning power.

Further, the control device 80 calculates an estimated value of the amount of water supplied from the water supply path 90 to the beverage transfer path 70 in the water shot control based on the output of the flow rate sensor 44 , and the estimated value is The gas on-off valve 63 and the water on-off valve 91 are controlled to reach the reference amount. That is, the control device 80 closes the gas on/off valve 63 until the estimated value of the amount of water supplied from the water supply path 90 to the beverage transfer path 70 reaches the reference amount in the water shot control. Also, the water on-off valve 91 is opened. In other words, the control device 80 closes the water on/off valve 91 when the estimated value of the amount of water supplied from the water supply path 90 to the beverage transfer path 70 in the water shot control reaches the reference amount. and also opens the gas on-off valve 63 . Accordingly, it is possible to suppress fluctuations in the amount of water supplied to the beverage transfer path 70 due to a change in water pressure or the like in the water shot control, and furthermore, it is possible to suppress a decrease in the cleaning power in the water shot control.

However, when cleaning the beverage supply system 1b , there is a risk that the user erroneously sets the position of the operation unit 53 of the dispense head 50 to the downward position. In this case, even if the water on/off valve 91 is opened and water is supplied to the dispensing head 50, mixing of water into the inside of the beverage container 20 is prevented by the above-described configuration of the dispensing head 50. .

When the position of the operation unit 53 is set to the downward position during water shot control, the flow of water is blocked by the dispensing head 50 and the water supply amount does not reach the reference amount. In addition, if the tap 32 is closed due to a user's erroneous operation during water shot control, the flow of water is blocked by the tap 32, so that the water supply amount does not reach the reference amount. For this reason, the control device 80 controls the water shot when the time until the estimated value of the amount of water supplied from the water supply path 90 to the beverage transfer path 70 reaches the reference amount is longer than the predetermined time in the water shot control. , a warning is output to the warning device 45 . Thereby, the user can be made to recognize an erroneous operation, and a user can be urged to wash in a correct order.

Moreover, in this embodiment, the 1st gas supply path 61 which supplies the gas for supplying a beverage, and the 2nd gas supply path 62 which supplies the gas for cleaning the beverage supply system 1b are separate. is provided with In this case, only when the beverage supply system 1b is cleaned, gas may be supplied from the second gas supply path 62 to the dispensing head 50 . For this reason, in the present embodiment, the gas opening/closing valve 63 is configured to close the second gas supply path 62 when de-energized and to open the second gas supply path 62 when energized.

<Washing treatment>

Hereinafter, with reference to the flowchart of FIG. 9, the above-mentioned control is demonstrated in detail. It is a flowchart which shows the control routine of the washing|cleaning process in 3rd Embodiment. This control routine is repeatedly executed by the control device 80 (specifically, the processor 83 ).

First, in step S101, the control device 80 determines whether a cleaning mode has been selected by the user. When the user requests cleaning of the beverage supply system 1 , the user selects a cleaning mode through the input device. The input device is electrically connected to the control device 80 and is configured, for example, as a button 49 (refer to FIG. 6 ) provided on the outer surface of the control box 40 . The control device 80 determines whether or not the cleaning mode is selected based on the output signal of the input device. When it is determined in step S101 that the cleaning mode is not selected, the present control routine ends.

On the other hand, when it is determined in step S101 that the cleaning mode has been selected, the control routine proceeds to step S102. In step S102, the water shot control shown in FIG. 10 is executed.

10 is a flowchart showing a control routine of water shot control. First, in step S201 , the control device 80 opens the water on-off valve 91 and closes the gas on-off valve 63 . Specifically, the control device 80 supplies electric power to the water on-off valve 91 .

Then, in step S202 , the control device 80 acquires the output of the flow rate sensor 44 .

Subsequently, in step S203 , the control device 80 controls the amount of water supplied from the water supply path 90 to the beverage transfer path 70 in the water shot control based on the output of the flow rate sensor 44 . Calculate the estimated value (EA). Specifically, the control device 80 calculates the estimated value EA of the amount of water by integrating the flow rate of the water detected by the flow rate sensor 44 .

Subsequently, in step S204, the control device 80 determines whether the estimated value EA of the amount of water is equal to or greater than the reference amount A. The reference amount A is predetermined based on experimental results and the like so that the cleaning power is increased. If it is determined that the estimated value EA of the amount of water is less than the reference amount A, the control routine proceeds to step S208.

In step S208, the control device 80 determines whether a predetermined time has elapsed since the water on-off valve 91 was opened and the gas on-off valve 63 was closed in step S201. The predetermined time is predetermined in consideration of the time required for the water supply amount to reach the reference amount A when the water pressure is low. If it is determined that the predetermined time has not elapsed, the control routine returns to step S202.

On the other hand, if it is determined in step S208 that the predetermined time has elapsed, the control routine proceeds to step S209. In step S209 , the control device 80 outputs a warning to the warning device 45 . For example, the control device 80 outputs a warning sound to the warning device 45 only for a predetermined period of time. Thereby, the user is notified that an erroneous operation is being performed. After step S209, the present control routine ends.

Further, when it is determined in step S204 that the estimated value EA of the amount of water is equal to or greater than the reference amount A, the control routine proceeds to step S205. In step S205 , the control device 80 closes the water on-off valve 91 only for a predetermined period of time and also opens the gas on-off valve 63 . Specifically, the control device 80 supplies electric power to the gas on-off valve 63 only for a predetermined period of time. The predetermined period of time is predetermined based on experimental results and the like so that the cleaning power is increased.

Then, in step S206, the control device 80 updates the number of executions N. Specifically, the control device 80 calculates the new number of executions N by adding 1 to the current number of executions N. The initial value of the number of executions N when the present control routine is started is zero.

Subsequently, in step S207, the control device 80 determines whether the number of executions N is equal to or greater than the threshold number Nth. The threshold number Nth is predetermined. If it is determined in step S207 that the number of executions N is less than the threshold number Nth, the control routine returns to step S201. That is, the water shot control continues.

On the other hand, when it is determined in step S207 that the number of executions N is equal to or greater than the threshold number Nth, the water shot control is terminated, and the control routine proceeds to step S103 shown in FIG.

In step S103, the control device 80 executes water discharge control in order to quickly discharge the water left in the flow path of the beverage by the water shot control. In the water discharge control, the control device 80 closes the water on-off valve 91 only for a predetermined time and also opens the gas on-off valve 63 . Specifically, the control device 80 supplies electric power to the gas on-off valve 63 only for a predetermined period of time. The predetermined time is predetermined in consideration of the time required for discharging water by gas.

Subsequently, in step S104 , the control device 80 closes the gas on-off valve 63 . Specifically, the control device 80 stops the power supply to the gas on-off valve 63 .

Subsequently, in step S105 , the control device 80 outputs an end alarm sound to the warning device 45 . At this time, even if the user forgets to close the tab 32, since the gas on-off valve 63 is closed, gas leakage is prevented. After step S105, the present control routine ends.

Further, the warning device 45 is configured as a display such as a liquid crystal panel, and may output a warning message as a warning. In this case, the warning device 45 is disposed on the outer surface of the control box 40 , and in step S209 of FIG. 10 , the control device 80 outputs, for example, a warning message to the warning device 45 only for a predetermined period of time.

In addition, the warning device 45 may be configured as a light emitting body such as a light emitting diode (LED) and output light as a warning. In this case, the warning device 45 is disposed on the outer surface of the control box 40 , and in step S209 of FIG. 10 , the control device 80 outputs light to the warning device 45 only for a predetermined time, for example.

In addition, the upper end of the main body 511 may be connected to the beverage transfer path 70 through a joint or the like.

The plunger 52' has a recess 522a. The concave portion 522a is formed on the outer surface of the plunger 52' and extends in the circumferential direction of the plunger 52'.

Further, the plunger 52 ′ has a spherical member 524 , a projection 525 , and a stepped portion 526 . The spherical member 524 , the protrusion 525 , and the stepped portion 526 are configured to prevent a backflow of the fluid from the fluid outlet 521 to the inside of the spear valve 21 , as in the first embodiment, a non-return mechanism function as

Moreover, as shown in FIG. 1, the dispensing head 50' is provided with the operation part 53. As shown in FIG. The operation part 53 slides the plunger 52' in the housing 51' by manual operation. The operation unit 53 is rotatably attached to, for example, the housing 51 ′, and is connected to the plunger 52 ′ so that the rotational motion of the operation unit 53 is converted into a linear motion of the plunger 52 ′. The operation unit 53 is configured as, for example, an operation lever.

In 5th Embodiment, the operation part 53 is rotatable between an upper position, an intermediate position, and a downward position. When the operation unit 53 is rotated from the upper position to the lower position through the intermediate position, the plunger 52 ′ moves vertically downward to approach the spear valve 21 . On the other hand, when the operation unit 53 is rotated from the lower position to the upper position through the intermediate position, the plunger 52 ′ moves upward in the vertical direction to move away from the spear valve 21 . Accordingly, the plunger 52' is slidable between an upward position and an intermediate position and a downward position.

In addition, the dispensing head 50' is provided with the on-off valve 54 similarly to 1st Embodiment. The on/off valve 54 is disposed inside the second fluid inlet 514 , that is, at the second fluid inlet 517 , and opens and closes the second fluid inlet 517 .

12 to 14 , the dispensing head 50' includes a first sealing member 301 , a second sealing member 302 , a third sealing member 303 , and a fourth sealing member 304 . ) and a seventh sealing member 307 . The first seal member 301, the second seal member 302 and the seventh seal member 307 are respectively disposed in circumferential grooves formed on the inner surface of the body portion 511 of the housing 51', It extends around the plunger 52'.

The first sealing member 301 is disposed above the first fluid inlet 513 in the vertical direction. The second sealing member 302 is disposed between the first fluid inlet 513 and the second fluid inlet 514 in the vertical direction. The seventh sealing member 307 is disposed below the second fluid inlet 514 in the vertical direction. Therefore, the 1st sealing member 301 is arrange|positioned uppermost in a vertical direction, and the 2nd sealing member 302 is arrange|positioned between the 1st sealing member 301 and the 7th sealing member 307 in a vertical direction. and the 7th sealing member 307 is arrange|positioned most downward in a vertical direction.

The third sealing member 303 contacts the valve case 22 of the spear valve 21 , and seals the space between the flange portion 512 and the valve case 22 . Accordingly, it is possible to prevent the fluid flowing into the spear valve 21 from flowing out through between the flange portion 512 and the valve case 22 .

A fourth sealing member 304 is disposed on the outer surface of the plunger 52' and extends around the plunger 52'. The 4th sealing member 304 is arrange|positioned below the recessed part 522a in the vertical direction, and is arrange|positioned near the spear valve 21 rather than the recessed part 522a.

The dispense head 50 ′ is configured to switch the communication state between the first fluid inlet 516 and the second fluid inlet 517 and the fluid outlet 521 . Specifically, the dispensing head 50' switches the communication state of the plunger 52' within the housing 51' by sliding.

In the fifth embodiment, when the beverage contained in the beverage storage container 20 is exhausted and the beverage storage container 20 is replaced with a new beverage storage container, the user sets the position of the operation unit 53 to the upward position. As a result, the plunger 52' is positioned in the upward position. Fig. 12 shows the dispensing head 50' when the plunger 52' is positioned at the upper position.

As shown in FIG. 12, when the plunger 52' is located in an upper position, the 1st sealing member 301 is located above the recessed part 522a in a vertical direction (axial direction). As a result, the first sealing member 301 comes into contact with the outer surface of the plunger 52' to seal the space between the housing 51' and the plunger 52'. Accordingly, even if water is supplied to the first fluid inlet 516 , it is possible to prevent water from flowing upward through the space between the housing 51 ′ and the plunger 52 ′.

In addition, when the plunger 52' is located in the upper position, the 7th sealing member 307 is located between the recessed part 522a and the 4th sealing member 304 in a vertical direction. As a result, the seventh sealing member 307 comes into contact with the outer surface of the plunger 52' to seal the space between the housing 51' and the plunger 52'. Accordingly, even if water is supplied to the first fluid inlet 516 , it is possible to prevent water from flowing into the spear valve 21 through the space between the housing 51 ′ and the plunger 52 ′. Therefore, by the 1st sealing member 301 and the 7th sealing member 307, water leakage at the time of replacing|exchanging the beverage container 20 can be prevented.

In addition, when the plunger 52 ′ is positioned in the upper position, the position in the vertical direction of the concave portion 522a and the second fluid inlet 517 coincides, and the on/off valve 54 faces the concave portion 522a. do. As a result, a space is created between the spindle 542 of the on-off valve 54 and the plunger 52', and no force opposing the biasing force of the spring 544 of the on-off valve 54 is generated. For this reason, the on-off valve 54 closes the second fluid inlet 517, so that the gas supplied to the second fluid inlet 517 can be introduced into the space between the housing 51' and the plunger 52'. none. Thereby, gas leakage at the time of replacing|exchanging the beverage container 20 can be prevented.

Accordingly, when the plunger 52 ′ is in the upward position, the first fluid inlet 516 and the second fluid inlet 517 are blocked from the interior of the beverage container 20 and from the fluid outlet 521 . In this state, the dispensing head 50 ′ is detached from the spear valve 21 , and the beverage container 20 is exchanged.

When cleaning the beverage supply system 1 , the user sets the position of the operation unit 53 to the intermediate position and opens the main cock of the water supply source 100 . As a result, the plunger 52 ′ is positioned at the intermediate position, and water is supplied to the first fluid inlet 516 . Fig. 13 shows the dispense head 50' when the plunger 52' is positioned at the intermediate position.

As shown in FIG. 13, when the plunger 52' is located in an intermediate position, the 1st sealing member 301 is located above the recessed part 522a in a vertical direction. As a result, the first sealing member 301 comes into contact with the outer surface of the plunger 52' to seal the space between the housing 51' and the plunger 52'. Accordingly, it is possible to prevent the water supplied to the first fluid inlet 516 from flowing upward through the space between the housing 51 ′ and the plunger 52 ′.

On the other hand, when the plunger 52' is positioned at the intermediate position, the positions in the vertical direction of the recessed portion 522a and the second sealing member 302 and the seventh sealing member 307 coincide, and the second sealing member ( 302 and the seventh seal member 307 face the recess 522a. As a result, a space is created between the second sealing member 302 and the seventh sealing member 307 and the plunger 52', and the water supplied to the first fluid inlet 516 passes through this space to the valve case ( 22) moves downward toward the inside.

Further, when the plunger 52 ′ is positioned at the intermediate position, the position in the vertical direction of the concave portion 522a and the second fluid inlet 517 coincides, and the on/off valve 54 faces the concave portion 522a. do. As a result, a space is created between the spindle 542 of the on-off valve 54 and the plunger 52', and no force opposing the biasing force of the spring 544 of the on-off valve 54 is generated. For this reason, the on-off valve 54 closes the second fluid inlet 517, so that the gas supplied to the second fluid inlet 517 can be introduced into the space between the housing 51' and the plunger 52'. none.

Further, when the plunger 52' is positioned at the intermediate position, the fourth sealing member 304 disposed on the outer surface of the plunger 52' does not come into contact with the gas flow passage closing portion 23 . For this reason, the 5th sealing member 305 arrange|positioned at the upper end of the gas flow path closing part 23 contacts the valve case 22 by the biasing force of the 1st spring 401, and the valve case 22 and gas Seal the space between the flow path closures 23 . Accordingly, water flowing into the valve case 22 through the space between the housing 51 ′ and the plunger 52 ′ can be prevented from flowing between the valve case 22 and the gas passage closing part 23 . .

Also, when the plunger 52 ′ is in the intermediate position, the lower end of the plunger 52 ′ does not contact the beverage passage closure 24 . For this reason, the beverage passage closing portion 24 is in contact with the sixth sealing member 306 by the urging force of the second spring 402 , and the sixth sealing member 306 is connected to the gas passage closing portion 23 and the beverage. Seal the space between the flow path closures 24 . Thereby, water flowing into the valve case 22 through the space between the housing 51 ′ and the plunger 52 ′ can be prevented from flowing between the gas flow path closing part 23 and the beverage flow path closing part 24 . can

Water flowing into the valve case 22 passes through the space between the gas flow path closing part 23 and the plunger 52' and the beverage flow path closing part 24 and the plunger 52' through the fluid outlet ( 521). Thus, when the plunger 52' is in the intermediate position, the first fluid inlet 516 is in direct communication with the fluid outlet 521, and the second fluid inlet 517 is connected to the interior and It is blocked from the fluid outlet 521 . When the tap 32 is opened in this state, the water supplied from the water supply source 100 flows through the flow path of the beverage, that is, the dispense head 50 ′, the beverage transfer path 70 and the beverage dispenser 30 (beverage introduction pipe). (31) and tab (32) are cleaned and discharged from tab (32). Water discharged from the tap 32 is accommodated in a drain container 200 installed in advance by a user.

When the beverage in the beverage container 20 is supplied to the beverage transfer path 70 by gas, that is, when the beverage is supplied from the beverage dispenser 30, the position of the operation unit 53 is set to the downward position by the user. As a result, the plunger 52' is located in the downward position. 14 is a partial cross-sectional view of the dispense head 50' and the spear valve 21 when the plunger 52' is in the down position.

As shown in FIG. 14, when the plunger 52' is located in a downward position, the 1st sealing member 301 is located above the recessed part 522a in a vertical direction. As a result, the first sealing member 301 comes into contact with the outer surface of the plunger 52' to seal the space between the housing 51' and the plunger 52'. Accordingly, even if water is supplied to the first fluid inlet 516 , it is possible to prevent water from flowing upward through the space between the housing 51 ′ and the plunger 52 ′. Further, the first sealing member 301 is in contact with the outer surface of the plunger 52' irrespective of the sliding position of the plunger 52'.

Moreover, when the plunger 52' is located in a downward position, the 2nd sealing member 302 is located above the recessed part 522a in a vertical direction. As a result, the second sealing member 302 comes into contact with the outer surface of the plunger 52' to seal the space between the housing 51' and the plunger 52'. Accordingly, even if water is supplied to the first fluid inlet 516 , it is possible to prevent water from flowing into the spear valve 21 through the space between the housing 51 ′ and the plunger 52 ′.

Further, when the plunger 52' moves from the intermediate position to the downward position, the spindle 542 of the on-off valve 54 is pressed by the inclined surface of the concave portion 522a. As a result, the spindle 542 moves against the biasing force of the spring 544 , and the on-off valve 54 opens the second fluid inlet 517 . The valve open state of the on-off valve 54 is maintained by pressing the spindle 542 on the outer surface of the plunger 52'. Further, the movement of the fluid upward from the second fluid inlet 517 is prevented by the second sealing member 302 . For this reason, the gas supplied to the second fluid inlet 517 passes through the on-off valve 54 and flows into the interior of the spear valve 21 through the space between the housing 51 ′ and the plunger 52 ′. do.

Further, when the plunger 52' moves from the intermediate position to the downward position, the lower end of the plunger 52' presses the beverage passage closing portion 24, and then, a fourth disposed on the outer surface of the plunger 52' The sealing member 304 presses the gas flow path closure 23 . As a result, the beverage passage closing portion 24 moves against the biasing force of the second spring 402 , thereby creating a space between the sixth sealing member 306 and the beverage passage closing portion 24 . Thereafter, the gas flow path closing portion 23 moves against the biasing force of the first spring 401 , thereby creating a space between the fifth sealing member 305 and the valve case 22 .

Accordingly, the gas flowing into the valve case 22 flows into the beverage container 20 through between the valve case 22 and the gas flow path closing part 23 . As a result, the liquid level of the beverage is pushed down by the gas, and the beverage rises through between the gas flow path closing part 23 and the beverage flow path closing part 24 . The rising beverage flows into the fluid outlet 521 through the through hole 527 formed at the lower end of the plunger 52'.

Thus, when the plunger 52' is in the downward position, the first fluid inlet 516 is blocked from the interior of the beverage receiving container 20 and from the fluid outlet 521, and the second fluid inlet 517 is the beverage It communicates with the fluid outlet 521 through the interior of the receiving vessel 20 . When the tab 32 is opened in this state, the beverage supplied from the beverage container 20 by gas is poured out from the tab 32 through the beverage transfer path 70 .

As described above, the user sets the position of the operation unit 53 to the intermediate position when cleaning the beverage supply system 1 . However, there is a risk that the user forgets to switch the operation unit 53 and water is supplied from the water supply source 100 to the dispensing head 50 ′ when the operation unit 53 is positioned at the upper or lower position. Also in this case, in this embodiment, the inflow of water into the inside of the valve case 22 is prevented by the plunger 52', the 2nd sealing member 302, and the 7th sealing member 307. Accordingly, it is possible to prevent mixing of the washing water with the beverage in the beverage container 20 during cleaning of the beverage supply system 1 without detecting the position of the operation unit 53 .

<Other embodiments>

As mentioned above, although preferred embodiment which concerns on this invention was described, this invention is not limited to these embodiment, Various correction and change can be implemented within description of a claim.

For example, the positional relationship between the first fluid inlet part 513 connected to the water supply path 90 and the second fluid inlet part 514 connected to the gas supply path 60 may be opposite to each other. That is, the first fluid inlet 516 may be disposed downstream of the second fluid inlet 517 , and the on/off valve 54 may be disposed at the first fluid inlet 516 . In this case, with respect to the dispensing head 50 shown in FIGS. 2 and 4 , the user sets the position of the operation unit 53 to the downward position when cleaning the beverage supply system 1 , and when supplying the beverage, the operation unit Set the position of (53) to the upward position. In addition, with respect to the dispensing head 50' shown in FIGS. 12 to 14 , the user sets the position of the operation unit 53 to the downward position when the beverage supply system 1 is cleaned, and the operation unit when the beverage is supplied. Set the position of (53) to the intermediate position.

In addition, in the dispensing head 50, the correspondence relationship between the position of the operation part 53 and the position of the plunger 52 may differ. For example, the dispensing head 50 may be configured such that the position of the plunger 52 becomes the upper position when the position of the operation unit 53 is the lower position. The same applies to the dispense head 50'.

Further, in the dispensing head 50 , the first fluid inlet 516 and the second fluid inlet 517 are disposed at the same position in the axial direction of the main body 511 of the housing 51 , and the main body portion (511) may be spaced apart in the circumferential direction. In this case, for example, two sealing members are disposed on the inner surface of the body portion 511, and when the plunger 52 is positioned at the upper position, one sealing member surrounds the second fluid inlet 517, and the plunger ( When 52 is in the down position, the other seal member surrounds the first fluid inlet 516 . In this way, when the first fluid inlet 516 and the second fluid inlet 517 are selectively sealed by the sealing member, the on/off valve 54 may be omitted.

In addition, the above-mentioned embodiment can be implemented by combining arbitrarily. That is, the dispense head 50' in the fifth embodiment may be used in the second to fourth embodiments.
