Description

  TECHNICAL FIELD The present invention relates to a structure for cleaning a beverage pipeline in a beverage supply apparatus including a beverage dispenser that cools and supplies a beverage such as draft beer, and particularly relates to a structure that circulates and cleans sponge balls in the pipeline. Is.

  FIG. 7 shows an example of a general beverage supply apparatus in which draft beer is supplied. In FIG. 7, reference numeral 121 denotes a beer dispenser, which instantly cools draft beer by a built-in cooling coil tube (not shown) and pours an appropriate amount of draft beer into a beer mug by opening and closing the pouring cock 122. It can be done. A beer barrel 123 stores draft beer. A dispenser head 124 is attached to the upper end opening of the beer barrel and is connected to the beer dispenser 121 via a supply hose 125. Reference numeral 126 denotes a carbon dioxide gas cylinder, which is attached to the dispenser head 124 via a hose 127 and is configured to pump draft beer in the beer barrel 123 to the beer dispenser 121 via a supply hose 125 by the pressure of the gas. It is.

  In such a beverage supply apparatus, various germs and dirt adhere to the inner wall of a pipeline (such as a supply hose and a cooling coil tube in a beer dispenser) through which the beverage flows. For example, since draft beer contains nutrients and inorganic components, these germs and the like adhere to the inner wall of the pipeline, causing the quality of draft beer supplied from this beer dispenser to deteriorate. For this reason, it is necessary to periodically clean the pipeline, and various methods and apparatuses for cleaning the pipeline have been proposed in this type of beverage supply device.

  The simplest method for cleaning this pipe line is a method in which a beer supply hose is directly connected to a tap, and tap water is passed through the pipe for cleaning. In addition, instead of a beer barrel, a barrel containing predetermined washing water is connected, and the operation of a dispenser head attached to the barrel allows the washing water in the barrel to flow through the pipeline using the gas pressure of the carbon dioxide cylinder. There are means for cleaning. Furthermore, as shown in Patent Document 1 and Patent Document 2, there is a device in which a special device for supplying cleaning water is provided and the pump is operated with carbon dioxide gas to supply the cleaning water.

  In this case, for example, as shown in paragraph 23 of Patent Document 2, the external beverage hose is removed from the dispenser head, and a sponge ball is inserted from the end of the hose so that the sponge ball circulates in the pipeline. There is also a means. By circulating the sponge balls, various kinds of dirt attached to the inner wall of the pipe line can be physically removed.

  And as a washing structure of the pipe line of the beverage supply device, a means of adopting a washing structure of the pipeline of the beverage supply apparatus provided with any one of the above sponge ball supply devices and any one of the above circuit changers was adopted. .

  The washing structure of the pipe of the beverage supply device having the above-described structure is as follows. First, in the sponge ball supply device, the sponge is very easily passed through the through hole of the supply device fixed between the supply hose and the hose connection portion of the dispenser head. The ball can be supplied to the pipeline. In this case, the sponge ball can be supplied to the pipe line by an extremely simple operation without removing the supply hose or temporarily stopping the supply of gas.

  On the other hand, in the circuit switching device, the flow path of the beverage is switched via the moving circuit portion, and the flow path is formed by separating the blocking device from the pipe line, so that the circulation of the sponge balls is obstructed.

  And the washing structure of the pipe of the beverage supply device according to the present invention is the one in which a sponge ball supply device is attached between the dispenser head and the supply hose, and a circuit switch is interposed in the middle of the pipe. When cleaning the pipeline, the sponge ball can be put into the pipeline very easily, and the sponge ball can be freely released in the pipeline by blocking the obstruction device that does not allow the sponge ball to pass through the circuit switch. It will be possible to wash the pipes reliably.

  Hereinafter, a preferred embodiment of a cleaning structure for a pipeline of a beverage supply device according to the present invention will be described with reference to the drawings. FIG. 1 shows an example of a structure for supplying a sponge ball for cleaning to a pipe line. In the figure, 1 is a dispenser head connected to an upper end opening of a beer barrel (not shown) or the like, and a supply hose (not shown) for supplying beer to a beer dispenser (not shown) at the upper end. ) Is formed, and at the lower end, a barrel connecting portion 3 for connecting to the upper end opening (not shown) of the beer barrel is formed. Reference numeral 4 denotes a cylinder connecting portion for connecting a carbon dioxide gas cylinder (not shown) for supplying beer by gas pressure. This dispenser head 1 is generally used in this type of beverage supply apparatus.

  Next, 11 is a sponge ball supply device, which is connected between the supply hose and the hose connection portion, and in a mode in which the sponge ball supply shaft 13 is slidably orthogonal to the cylindrical main body 12. is there. The main body 12 forms a beer flow path 14 at the center in the axial direction, a hose connection portion 15 having a shape to which a beer supply hose can be connected at the outer periphery of the upper end, and an upper end of the dispenser head 1 at the lower end. A dispenser head connecting portion 16 having a shape connectable to the hose connecting portion 2 is formed.

  The sponge ball supply shaft 13 is a rod-like body that is slidably attached to a shaft hole 17 provided in the middle portion of the main body 12 and perpendicular to the flow path 14, and is 2 perpendicular to the axis of the rod-like body. Circulation holes 18 and 19 are provided at locations, and the circulation holes 18 and 19 can communicate with the flow path 14 of the main body 12. Then, by pushing and pulling the sponge ball supply shaft 13 in the axial direction, the flow path 14 and either one of the flow holes 18 and 19 communicate with each other, and the liquid can flow through the flow path 14.

  Then, the use procedure of this sponge ball supply apparatus 11 is demonstrated. During normal use, the dispenser head 1 is connected to the beer barrel via the barrel connecting portion 3, and the carbon dioxide cylinder is connected to the cylinder connecting portion 4. And as shown in FIG. 1, the said sponge ball supply apparatus 11 is connected to the hose connection part 2 of the upper end of the dispenser head 1, and also a supply hose is connected to the hose connection part 15 of this sponge ball supply apparatus 11. . At this time, the sponge ball supply shaft 13 of the sponge ball supply device 11 is in a state where the flow hole 18 communicates with the flow path 14. When gas pressure is supplied from a carbon dioxide gas cylinder in such a connected state and an injection cock (not shown) of the beer dispenser is operated, draft beer in the beer barrel is supplied by gas pressure to supply pipes such as a supply hose and a beer dispenser. You can infuse draft beer into a mug.

  When cleaning the pipeline, the dispenser head 1 is once removed from the beer barrel and replaced with a mini barrel containing cleaning water. When the beer dispenser is operated in this state, the cleaning liquid in the mini barrel flows through the pipeline, and the pipeline can be washed. At this time, when the sponge ball (S) is inserted into the circulation hole 19 exposed to the outside of the sponge ball supply shaft 13 and the sponge ball supply shaft 13 is pushed in the sponge ball supply device 11, the sponge ball supply device 11. The flow path 14 and the flow hole 19 communicate with each other, and the sponge ball (S) is supplied into the pipe. Therefore, sponge balls circulate in the pipeline, and various stains adhering to the inner wall of the pipeline can be physically and efficiently removed to clean the pipeline. That is, according to the present apparatus, the sponge ball can be supplied to the pipe line by an extremely simple operation without the need to open and close the gas cylinder or to remove the supply hose as in the prior art.

  Next, FIG. 2 shows another embodiment of the sponge ball supply device, and the dispenser head 1 will be described with the same reference numerals as in the above embodiment. In FIG. 2, reference numeral 21 denotes a sponge ball supply device in which a supply ring 23 is fitted on the outer periphery of the intermediate portion of the cylindrical main body 22. The main body 22 forms a beer flow path 24 in the center in the axial direction, a hose connection portion 25 having a shape connectable to a beer supply hose on the outer periphery of the upper end, and a lower end of the upper end of the dispenser head 1. A dispenser head connection portion 26 having a shape connectable to the hose connection portion 2 is formed. Further, an insertion hole 27 into which a sponge ball can be inserted is formed in the side surface of the intermediate portion of the main body 22.

The insertion hole 27 is normally closed by shifting the positions of the insertion hole 27 and the through hole 28 so that the liquid flows in the flow path 24, and the positions of the insertion hole 27 and the through hole 28 are made to coincide. Thus, the sponge ball (S) can be introduced into the flow path 24 from the communicating hole.

  Then, the use procedure of this sponge ball supply apparatus 21 is demonstrated. As in the previous embodiment, the sponge ball supply device 21 is connected between the beer supply hose and the dispenser head. If the positions of the insertion hole 27 and the through hole 28 are shifted as described above, the flow path 24 can be secured. In this state, draft beer can be injected into the mug by operating the injection cock of the beer dispenser. When washing the pipeline, a mini barrel containing washing water is connected instead of the beer barrel, and the washing water is circulated by the operation of the beer dispenser to wash the pipeline. At this time, the gas cylinder is closed to temporarily stop the flow of the cleaning water, and then the insertion hole 27 and the through hole 28 are made to coincide with each other and the sponge ball (S) is inserted. If the positions of the insertion hole 27 and the through hole 28 are shifted again and the gas cylinder is opened, the sponge balls circulate through the pipe along with the washing water, and the pipe inner wall can be washed.
