At present, the beer dispenser 1 is set in the beer dispensing ready operation state, and as shown in the figure, the signal output by the control unit 90 turns on the dispensing / washing lamp 92, and the first on-off valve 11 and the second The on-off valve 12 is opened, the third on-off valve 13 is closed, and the beer derivation probe 43 is located at the lower position (position B), so that the reed switch 51 sends a position signal (position B) to the controller 90. Is in the state of output. Accordingly, the carbon dioxide gas stored in the carbon dioxide gas cylinder 60 passes through the first on-off valve 11 and is supplied from the gas pipe line 15 through the connector 16 to the air cylinder 31 of the dispense head 30 from the gas pipe line 17. Similarly, the carbon dioxide gas that has passed through the second on-off valve 12 and the check valve 19 is supplied from the manifold 20 to the cleaning water, the gas common pipe 21 and the connector 22 to the washing water and the gas common pipe 23 to the dispensing head 30. Since it is supplied to the gas inlet 32, the gas inlet 32 and the gas inlet passage of the outlet 3 are made to communicate with each other, and the beer outlet 3 and the beer outlet passage of the beer outlet 33 are connected to make beer from the beer barrel 2. It can be derived (see FIG. 3). When the operation lever 8a is tilted, the valve of the dispense valve 8 is opened, and the beer pushed out from the beer barrel 2 by the pressure of the carbon dioxide gas supplied from the carbon dioxide gas cylinder 60 is the beer outlet 33 of the dispense head 30, the beer pipe. It passes through the passage 4, is cooled by the cooling coil 7, and is poured out from the spout 8 b of the dispense valve 8.

  And in order to wash | clean the beer pipeline 4, the cooling coil 7, and the dispense valve 8 which are drink supply pipelines, when the dispense valve 8 is opened and the pouring / washing switch 91 is pushed (T1), a signal is sent to the control unit 90. The control unit 90 outputs a signal based on the control data stored in the memory 95, blinks the dispensing / cleaning lamp 92, and closes the second on-off valve 12. When the first on-off valve 11 is closed at T2 (for example, after a lapse of 1 second from T1) and the carbon dioxide gas is discharged, the beer derivation probe 43 fixed to the piston 31a of the air cylinder 31 is in the upper position (position A). The reed switch 51 outputs a position signal (position A) to the control unit 90, the gas inlet 32 and the beer outlet 33 are closed from the connection passage of the spout 3 and the gas inlet 32 and the beer guide The outlet 33 is in direct communication (see FIG. 2). Further, the third on-off valve 13 is opened at T3 (for example, after a lapse of 2 seconds from T2), and the cleaning water supplied from the water supply 70 is supplied to the third on-off valve 13, the check valve 25, and the manifold 20 from the cleaning water. When the cleaning water is supplied to the gas inlet 32 from the gas common pipe 23 via the gas common pipe 21 and the connector 22, as shown in FIG. 6, the supplied wash water is used for extracting beer from the carbon dioxide gas passage 32a. The probe 43 flows through the beer outlet port 33, the beer pipe 4 and the cooling coil 7, and the beer remaining in the pipe is pushed out and washed to be discharged from the spout 8 b of the dispense valve 8. The time for opening the third on-off valve 13 (time from T3 to T4, for example, 20 seconds to 60 seconds) is stored in advance in the memory 95 of the control unit 90, and the timer 96 counts the clock. When the predetermined time T4 is reached, the third on-off valve 13 is closed, and the cleaning with the cleaning water ends.

  Next, when the second on-off valve 12 is opened at T5 (for example, after 1 second from T4), the carbon dioxide gas stored in the carbon dioxide gas cylinder 60 passes through the second on-off valve 12 and the check valve 19. Then, the cleaning water and the gas common line 21 and the connector 22 are supplied from the manifold 20 to the cleaning water and the gas common line 23 to the gas inlet 32, and the supplied carbon dioxide gas is supplied from the beer outlet 33 to the beer pipe. The washing water remaining in the pipes of the passage 4, the cooling coil 7, and the spout 8b of the dispense valve 8 is blown out and discharged from the spout 8b. After this gas blow is continued until T6 (for example, 10 seconds to 30 seconds), the second on-off valve 12 is closed, and the supply of carbon dioxide gas to the gas inlet 32 of the dispense head 30 is stopped. Then, at T7 (for example, after 1 second from T6), the dispensing / cleaning lamp 92 finishes blinking, the beverage supply line cleaning control of the control unit 90 is completed, the dispensing valve 8 is closed, and the cleaning operation is completed. . Even after the beverage supply line cleaning is completed, the beer line 4 and the cooling coil 7 still have a carbon dioxide gas having an effect of suppressing the growth of bacteria, so that the drink supply line can be kept hygienic. it can.

  Next, in order to start beer pouring, when the pouring / washing switch 91 is pressed (T8), a signal is output to the control unit 90, and the control unit 90 generates a signal based on the control data stored in the memory 95. Is output, the discharge / cleaning lamp 92 is turned on, a signal is output to the second on-off valve 12 to open the valve, and the carbon dioxide gas stored in the carbon dioxide gas cylinder 60 is transferred to the second on-off valve 12, After passing through the check valve 19, the cleaning water is supplied from the manifold 20 to the gas inlet 32 of the dispensing head 30 from the cleaning water and the gas common pipe 23 through the connector 22. Then, at T9 (for example, after 1 second from T8), the first on-off valve 11 is opened, and carbon dioxide gas is supplied from the gas pipe 17 to the air cylinder 31 of the dispense head 30, and the beer derivation probe 43 is set. When moved to the lower position (B position), the reed switch 51 outputs a position signal (B position) to the control unit 90, and the packing 45 provided near the tip of the beer derivation probe 43 pushes down the dip tube 35, leading to the tip 36. A gas introduction passage is formed between the outer edge of the sleeve 34 and the valve seat 37 inside the sleeve 34 so that carbon dioxide gas is introduced into the beer barrel 2 as a beer outlet pressure, and the tip 44 of the beer outlet probe 43 is connected to the dip tube 35. The tip 39 and the valve body 41 are pushed down to form a beer outlet passage between the beer outlet probe 43 and the beer barrel 2 and stored in the beer barrel 2. Le is derivable state receives the derived pressure of carbon dioxide gas (see FIG. 3). Here, when the operation lever 8a of the dispensing valve 8 is tilted, the valve is opened, and the beer pushed out from the beer barrel 2 by the pressure of the carbon dioxide gas supplied from the carbon dioxide gas cylinder 60 is discharged from the spout 3 into the beer outlet of the dispensing head 30. 33, passes through the beer pipeline 4, is cooled by the cooling coil 7, and is poured out from the spout 8b.

  The control unit 90 outputs a signal based on the control data stored in the memory 95 to blink the dispensing / cleaning lamp 92, closes the second on-off valve 12, and closes T2 (for example, for 1 second from T1). When the first on-off valve 11 is closed and the carbon dioxide gas is discharged after the elapse of time), the malfunction of the air cylinder 31 or the malfunction of the beer outlet probe 43 fixed to the piston 31a being caught by the main body case 46, etc. Occurs, the beer outlet probe 43 stops at the lower position (position B), and the gas introduction passage is still formed between the outer edge of the tip 36 of the dip tube 35 and the valve seat 37 inside the sleeve 34. When the third on-off valve (washing water on-off valve) 13 is released in this state, the washing water supplied from the water supply 70 is supplied from the check valve 25 and the manifold 20 to the washing water and gas common pipe 2. The cleaning water flows from the gas common line 23 through the connector 22 into the beer barrel 2 through the gas introduction port 32. However, a predetermined time (T2 and T2) after the first on-off valve 11 is released. If the control unit 90 cannot receive the position signal (position A) from the reed switch 51 within a time shorter than the setting time T3, for example, 1 second, it is determined that an abnormality has occurred in the dispensing head 30. Then, an abnormal signal is output to cause the abnormal lamp 92 to blink, and the third on-off valve 13 is not released so as to stop the introduction of the cleaning water (see FIG. 7). As described above, the controller 90 can control each on-off valve by determining whether or not there is a malfunction in the dispensing head 30 based on the position signal (A position, B position) output from the reed switch 51. It is possible to prevent water from entering the beer barrel 2.
