Description

[Detailed description of the invention] Industrial field of application This invention relates to a cleaning tool for cooling coils of draft beer barrel dispensers and the like.

2. Description of the Related Art A device shown in FIG. 5 is known as a device for instantaneously cooling and dispensing carbonated beverages, such as barreled draft beer. 1 is a dispenser (cooling tank) having a spiral cooling coil 2 therein for cooling the passing draft beer, 3 is a draft beer barrel, 4 is a dispense head attached to the mouth of the draft beer barrel 3, and 5 is a dispenser head that is attached to the mouth of the draft beer barrel 3. A beer hose connects the mouth of the barrel 3 and one end of the cooling coil 2 via a dispense head 4, 6 is a collar attached to the other end of the cooling coil 2, and 7 is a carbon dioxide cylinder.

In the above system, to dispense draft beer, the carbon dioxide gas in the carbon dioxide gas cylinder 7 is introduced into the draft beer barrel 3 through the gas passage of the dispensing head 4 by opening the pressure reducing valve, and the introduced carbon dioxide gas is The draft beer in the barrel was supplied to the cooling coil 2 through the beer passage of the dispense head 4 and the beer hose 5 through a siphon pipe (not shown) under pressure, and the draft beer was cooled to an appropriate temperature while passing through the cooling coil 2. After that, pour out by opening the pot 6. During such pouring, the draft beer to be poured is cooled by cooling coil 2,
It progresses or stays in the beer hose 5, and especially in the cooling coil 2, it is sometimes cooled from the surroundings, so that the dissolved substances in the beer tend to precipitate.
Eventually, some will adhere to the inner wall of the cooling coil 2. Therefore, after using the dispenser 1, if it will not be used for a while, such as during a certain period of time at night, it is necessary to carefully clean the cooling coil 2, etc., through which beer passes, to remove deposits that have adhered to the inner walls.

Conventionally, in order to clean the cooling coil 2 as described above, the beer hose 5 is removed from one end of the cooling coil 2 as shown in FIG.
Connect the other end of the cooling coil 2 from which the
Insert a sponge ball (not shown) larger than the diameter of cooling coil 2 into cooling coil 2 along with tap water.
Water was allowed to flow through the tank for an appropriate amount of time and at a predetermined pressure. When this is completed, one end of the cooling coil 2 and the tap water tank 8 are connected with a hose 9, and in the opposite direction to the above, the sponge bulb is flowed together with tap water into the cooling coil 2 at a predetermined water pressure. Tap water was passed through the bulb in both forward and reverse directions to remove deposits adhering to the inner wall of the cooling coil 2. The reason why the tap water flows between the sponge bulb and the tap water in both the forward and reverse directions is only from one direction in the case of stubborn dirt that adheres to the inner wall of the cooling coil 2, which is difficult to remove.The cooling coil 2 has a spiral shape. This is because the cleaning effect is not very good and it is extremely difficult to completely remove dirt.

Problems to be solved by the invention By the way, in the above method, when the sponge bulb and tap water are flowing in different directions, the hose 9 connected to the cooling coil 2 is connected alternately to one end or the other end of the cooling coil 2. There was a problem that the work was complicated and the workability was poor.

Therefore, the object of this invention is to solve the problems of the conventional ones and to provide a cleaning tool that can perform cleaning operations efficiently with simple operations.

In the above embodiment, tap water from the tap water tank 8 is supplied to the liquid supply cylinder 13, but the invention is not limited to this. Therefore, the cleaning liquid may be used to supply the liquid supply cylinder 13.

Effects of the invention Since this invention has the above-mentioned configuration, one end of the first hose is connected to the liquid supply cylinder with a four-way socket, the other end is connected to the cleaning liquid supply device, and one end is connected to the first hose with a four-way socket. The other end of the second hose connected to the connecting tube is connected to one end of the cooling coil, and the other end of the third hose, one end of which is connected to the second connecting tube with a four-way socket, is connected to the other end of the cooling coil. Then, by supplying the cleaning liquid from the supply device and switching the switching valve body, the cleaning liquid directs the elastic body stored in the first storage chamber or the second storage chamber toward the second storage chamber or the first storage chamber. Since the elastic body can be passed through the cooling coil as many times as desired, the cleaning process can be performed efficiently with simple operations.

Further, when moving the elastic body, the first and second
Since the connecting tube is transparent, it is possible to visually confirm the movement of the starting and ending points of the elastic body due to switching of the switching valve body, and therefore, the movement of the elastic body due to switching of the switching valve body can be confirmed visually.
It is possible to quickly deal with problems such as poor movement.

Moreover, the fact that the arrival of the elastic body to the starting and ending point can be confirmed means that the elastic body has already reached the first storage chamber from the second storage chamber to the second storage chamber or the first storage chamber. This eliminates the problem of insufficient use of the elastic body, where only the cleaning liquid continues to flow indefinitely without being able to see where the elastic body is, and the flow of the cleaning liquid can be switched without loss time, making it possible to constantly clean the elastic body back and forth, thereby increasing cleaning efficiency. can.

Furthermore, since the stopper member is removably provided on the switching valve body side of each storage chamber of the first and second connecting cylinders, which are provided to protrude from the outer surface of the casing, the aforementioned malfunction of the elastic body may occur. Not only can it be easily repaired by removing the stopper member when the stopper member is damaged, but it also has excellent effects such as being able to be removed and easily cleaned or replaced when dirt adheres to the stopper member. There is.
