"Flushing device for a beverage dispenser"

The invention relates to a flushing device for a beverage dispensing system essentially consisting of a carbon dioxide bottle and a beverage barrel, provided with a lock-coupling combination for closing the barrel or coupling it with the line leading to the counter and Colilensaur line.

A flushing device is already known in which there is a connection in the line between a beer keg and the counter is arranged, to which a water pipe can be connected, so that after emptying the beer barrel or after Curfew, water can be allowed in the beer line to rinse and water instead of beer in the same Maintain management when the system is out of order.

The disadvantage of the known device is that the line section between the water connection and the beer keg, as well as .h f. connection combination of the beer line on the beer keg is not rinsed.

It is the object of the invention to create a flushing device in which all parts of the beverage dispensing system that come into contact with the beverage are flushed through.

ORtGlMAL SMSPSOTED

For this purpose, the invention proposes the flushing device with a connection to be arranged in the carbon dioxide line for a lockable water line, as well as a to provide a non-return valve arranged in the carbon dioxide line between the carbon dioxide bottle and the connection.

The invention uses the fact that the lock-coupling combination is formed on the beverage barrel in such a way that when the beverage barrel is closed, the carbonic acid pressure takes effect immediately on the beverage line to the counter. By now branching off the carbon dioxide line and a branch is connected to a water supply, can be emptied after closing the beverage barrel or not, the water supply is released, causing water to flow through the carbon dioxide line and the lock-coupling combination flows to the beverage line. The check valve in the carbon dioxide line, the "upstream" prevents water from flowing into the carbon dioxide bottle.

The well-known lock-coupling combination of a beer keg is designed with a manually operated mechanism, by means of which the beer keg can be opened after the vAirschluss-coupling combination via, for example, a Bayonet lock is arranged on the beer keg. According to a further development of the invention, this operating mechanism can be adjusted by means of a piston-cylinder.

709824/0726

The pressure medium required to move the piston in the cylinder can particularly advantageously extract the piston acid tt.it; the carbon dioxide bottle belonging to the beer dispenser.

in a preferred embodiment of the invention is ii'ii'iioration of the carbonic acid cylinder and the water pipe • •! I'lctrisch effected, the electrical circuit in such a way That is realized by switching a single Sehalter, the closure-coupling combination of the keg viii. Is closed, so that the beer line from the contents c.itstä barrel is disconnected and the water supply at the same time he follows. The control switch can be arranged near the counter, so that the operating personnel only to switch the switch and then tap until the entire line is filled with water.

The above and further features of the invention are referred to below on the basis of an exemplary embodiment described in more detail on the drawing. They represent:

Lock-coupling combination 2, of which the detachable part i is coupled to the line 5 leading to the carbon dioxide bottle 4 and a line 7 leading to the counter 6.

il.M-h the main feature of the invention is the carbon dioxide ii'i.j 5 is provided with a connection 8, which is connected via a valve 9 mi nine water pipe 10 is connected. Between the ■. '!.' ■ «.. • connection 8 and the carbonic acid bottle 4 is in the carbon -.-. R.utre line 5 a check valve 11 is arranged.

If the locking / coupling ^{combination 2, 3 comprises a valve 12 belonging to the I 1} ...! Detect, which is pressed against a seat 14 by springs 13. A ball valve 15 is arranged in the valve 12 and is pressed by a spring 16 against the valve seat 17 connected to the main valve 12.

In the detachable part 3 of the lock-coupling combination, a hollow operating rod is guided that against the ball valve 15 presses and then with a shoulder arranged around the rod 18 the valve 12 against the action .If.'r springs 13 pushes downwards, which position in the figure dar ^ i-.si .. ·! ι t is :. When the operating rod 18 moves upward vvi rd, Ruh ι the Kiujel 15 against their seat 17 and that Valve 12 against its seat 14.

The up and down operating movement of the rod 18 is

709824/0726

according to the invention by means of a cylinder-piston mechanism brought about, on the one hand with an ear connected to the detachable 'Peil 3 and on the other hand with a rocker arm is coupled, which acts on the operating rod 18.

The piston-cylinder mechanism 19 is preferably by means of carbonic acid originating from the carbonic acid bottle 4 actuated, the lines being shown schematically by dash-dotted lines 20 in the drawing.

The control of the double-acting in this version Cylinder 19 takes place by means of a two-way valve 21, which is electrically in one position and in by means of a spring the other position is brought.

The two-way valve 21 and the valve 9 for the water are operated with the same electrical control circuit 22 brought about. A switch 23, which is preferably arranged near the counter 6, is arranged in the control circuit 22.

The device works as follows:

When the switch 23 is open, the control circuit 22 is voltage-free, whereby both the valve 9 and the valve 21 are pressed into their position by their adjusting springs that the The water supply is shut off and the carbonic acid line is fed with carbonic acid, so that the cylinder disconnects the operating

709824/0726

rod 18 pushes down, causing the beer from pass 1 over the riser in the barrel, the ball valve 15 and the operating rod 18 to the beer line 7 flows. The pressure on the barrel is brought about that carbon dioxide on the bottle 4 via the line 5, the closure-coupling combination 2, 3 reaches the valve 12 raised from its seat into the space above the beer in barrel 1 and pressurized the beer. When the switch 23 is closed, the control circuit 22 is energized, the valve 21, and the valve 9, moved into the other position, in such a way that the cylinder 19 assumes a different position, the .stab 18 is moved upwards, the ball valve 15 and the valve 12 closes, and at the same time the water over the line 8 enters the carbon dioxide line 5. By moving the rod 18 upward, a connection is established between the carbon dioxide line 5 and the operating rod 18, whereby the water through this line 5 and this operating rod 18 arrives in the beer line. the end The drawing clearly shows that the water cannot flow in the direction of the carbon dioxide bottle 4 because the check valve 11 then becomes effective.

In the embodiment shown, it can be clearly seen that it is only wet when the switch 23 is in the closed position the rinse cycle of the beer dispenser can be started, This ensures that if the mains voltage fails, flushing will not take place, but will be tapped can.

Fig. 2 shows an alternative embodiment of the invention Flushing device, which embodiment differs from the preceding essentially by a separate valve Ln of the carbon dioxide line 5 between the bottle 4 and the Beer barrel 1 differs.

In the embodiment shown, the valve is a electromagnetic valve 24, which by means of a switch

25 is switched. The switch 25 is in series with the switch 23 and is with a switch 26 in the power line coupled to the electromagnetic valve for shutting off the water. The coupling between switch 25 and

26 is such that when energizing the electromagnetic. Valve 24, the magnetic valve 9 is not energized.

The advantage of an additional valve in the carbon dioxide line 5 is that the loose part 3 of the lock-coupling combination can easily be placed on another barrel 1. When the original barrel 1 is empty, it closes the operator presses the switch 23, whereby initially. Water through the lock-coupling combination to the Beer line 7 is performed. When uncoupling the loose Part 3, however, must include the water supply and the carbon :; äureleiiung 5 are locked. For this purpose, the Switches 25, 26 switched over, whereby the valve 24 and 9 shut off the supply of carbonic acid or water. After that you can the loose part 3 of the lock-coupling combination released
