Description

[Detailed Description of the Invention] a. Industrial Application Field The present invention relates to a spouting pipe attachment device for a beverage dispenser.

b. Conventional technology Conventional frozen beverages (called frozen)
is manufactured by supplying raw materials such as syrup, water, carbon dioxide gas, etc. into a cooling chamber, cooling and freezing these raw materials while stirring in the cooling chamber, and pouring them out from a pouring pipe with a pouring valve. Since the cooling chamber is under pressure, the fitting of the spout pipe to the cooling chamber must be able to withstand that pressure.

That is, as shown in FIG.
A cooling pipe 2 is spirally wound around the outer periphery of the cooling pipe 2, and is connected to a refrigeration system (not shown). A stirring blade 3 is provided in the cooling chamber 1 , and the stirring blade 3 is supported by a bearing on a lid 5 and is rotationally driven by a drive device 4 . The spout valve 9 is connected via a spout pipe provided on the lid 5 of the cooling chamber 1, the details of which are shown in FIG. A mounting hole 5a is formed in the lid 5, and a spouting pipe 6 is inserted into the mounting hole 5a, and is fastened with a nut 8 from the outside of the lid 5. A flange 14 is provided on the head 6a of the spouting pipe 6, a screw 16 is provided on the body 6b, and a spouting valve 9 is connected to the outlet with a cap nut 10 at the end thereof.
- fixed connection via ring 11; When tightening the nut 8, a groove 13 provided adjacent to the screw 16 is formed by applying a tool such as a spanner to the groove 13 to prevent the spout pipe from rotating while rotating the nut 8. This is for tightening.

Note that 15 is a passageway for pouring beverages.

As shown in FIG. 5, when the flange 14 projects inward from the inner surface 5b of the lid 5, the nut 8 can be rotationally tightened by gripping the flange 14 with a tool.

C. Problems to be solved by the invention In the case of conventional spout pipe attachment devices, it is necessary to provide a groove in the spout pipe and tighten the nut while using another tool in the groove to prevent rotation. There were processing problems in that the spout pipe was made longer and the grooves were processed, and there were work problems in that the tightening work was complicated. In addition, if the flange protrudes into the cooling chamber, good results may not be obtained when stirring and dispensing the frozen beverage, and the nut may become loose when the frozen beverage is inside the cooling chamber. In such cases, there was a problem in that the lid could not be refastened unless the lid was removed after all the frozen beverage had been expelled.

It is conceivable that the shape of the flange of the spouting tube is other than round, for example, polygonal, and that a concave portion of the same shape is formed in the lid, but this poses the problem of requiring special and difficult machining.

The present invention was made in order to solve these conventional problems, and the object is to provide a pouring pipe attachment device for a beverage dispenser that has a simple structure and is easy to tighten. It is.

d Means for Solving the Problems In order to achieve the above object, the present invention includes a cooling chamber for cooling and stirring the beverage, a mounting hole formed in the lid or wall of the cooling chamber, and a flange on the head. In the spout pipe mounting device for a beverage dispenser, the spout pipe has a screw for tightening on the body, and the spout pipe is inserted into the mounting hole and tightened from the outside with a nut. A mortar-shaped taper part is formed on one side, and a conical part is provided at the head of the spouting pipe to match the taper part, and when the spouting pipe is tightened, the flat surface of the flange and the lid of the cooling chamber are formed. Or, it is configured so that it is flush with the inner surface of the wall.

e Action A mortar-shaped taper part is formed inside the mounting hole, a conical part that matches the taper part is provided at the head of the spouting pipe, and the spouting pipe inserted into the mounting hole is tightened from the outside with a nut. Since the nut is tightened by rotation, the conical part of the spout pipe enters the tapered part of the mounting hole, and the contact friction between the two eliminates idle rotation of the spout pipe, making it easy to tighten the nut. .

In addition, when the spout pipe is tightened, the flat surface of the flange and the inner surface of the lid or wall of the cooling chamber are flush with each other, so that stirring and cooling of frozen beverages within the cooling chamber is possible. There is no obstacle to pouring from the chamber.

f. Embodiment Hereinafter, an embodiment of the present invention will be described with reference to a beverage dispenser pouring pipe attachment device shown in the drawings.

FIG. 2 shows a side view of the spouting pipe, and FIG. 3 shows a cross section showing the relationship between the lid 5 of the cooling chamber 1, the spouting pipe 6, and the nut 8.

Note that the same or equivalent parts as in the conventional spouting pipe attachment device are given the same reference numerals. Further, since the entire cooling chamber 1 has already been described, the description thereof will be omitted here.

In FIG. 2, the spouting pipe 6 has a flange 14 on the head 6a, and the flange 14 is formed into a conical part 17 having an inverted conical shape. Further, the body portion 6b has only a screw 16. Note that 7 and 11 are grooves for O-rings, groove 7 is for O-rings to form a seal between spout pipe 6 and lid 5, and groove 1
1 is for an O-ring for forming a seal between the spout pipe 6 and the spout valve 9. Further, 18 is a flat surface of the flange of the spouting pipe, and the spouting pipe 6 is connected to the lid 5.
This is a portion that forms a plane flush with the inner surface 5b of the lid 5 when it is inserted into the mounting hole 5a and tightened with the nut 8.

Insert the spouting pipe 6 into the mounting hole 5a of the lid 5 from inside the cooling chamber 1, screw the nut 8 onto the screw 16 from the outside, and turn the nut 8, so that the head 6 of the spouting pipe 6
The conical portion 17 of a contacts the tapered portion 19 of the mounting hole 5a. Furthermore, when the nut 8 is rotated, the conical part 1
The resistance due to the contact friction between the spout 7 and the tapered portion 19 is increased, and the spout tube 6 no longer rotates along with the rotation of the nut 8, so that the nut 8 can be firmly fastened.

With the spouting tube 6 firmly fastened to the lid 5, the conical portion 17 and the tapered portion 19 are aligned so that the flat surface 18 of the flange 14 and the inner surface 5b of the lid 5 are flush with each other.
The shape and dimensions of the pipe are determined, and the spout pipe 6 is connected to the lid 5
When firmly fastened, the flat surface 18 of the flange 14 and the inner surface 5b of the lid 5 become flush with each other, so the flange 14 becomes an obstacle when the frozen beverage is stirred in the cooling chamber 1. There is no problem, and there is no problem when the frozen beverage is poured out from inside the cooling chamber 1.

The pouring pipe 1 does not rotate with the rotation of the nut 8 even if it is not fixed with a tool, so it can be easily tightened by rotating the nut 8, and the pouring tube 1 can be easily tightened by rotating the nut 8. When manufacturing the pipe, there is no need to provide a groove for fixing with a tool, and the screw 16 to which the nut 8 is screwed and the screw to screw the cap nut 10 for connecting the spout valve 9 can be integrated. Since it only needs to be processed, its production is easy.

Note that the conical part does not necessarily have to be formed into a flange, but by forming the conical part following the disc-shaped flange and forming the mortar-shaped taper part of the corresponding mounting hole in the same shape, the same result can be achieved. action, you can get a high price.

g. Effects of the invention According to the invention, in the spout pipe mounting device for a beverage dispenser in which the spout pipe is inserted into the mounting hole of the cooling chamber and tightened with a nut from the outside, a mortar is installed inside the mounting hole. A conical part is formed at the head of the spouting pipe to match the tapered part, and when the spouting pipe is tightened, the flat surface of the flange and the inner surface of the lid or wall of the cooling chamber are formed. Since it is constructed so that the two sides are flush with each other, the spout pipe can be easily installed in the cooling chamber by simply turning the nut without having to secure the spout pipe with a tool. It can be fastened easily and is easier to manufacture than conventional ones. Further, when the pouring pipe is attached to the cooling chamber, no unevenness is formed on the inner surface of the cooling chamber, so stirring of the frozen beverage within the cooling chamber and pouring out of the frozen beverage from the cooling chamber are extremely smooth.
