2. Description of the Related Art As a beverage cooling device of this type, there has been known one in which a heat exchange pipe is passed through an insulating container containing cooling water (Japanese Utility Model Publication No. 63-30715). This device requires a device for cooling and circulating the cooling water, which makes the device bulky and requires a power supply. Therefore, it is not suitable as a beverage cooling device that is easily used at various events such as outdoors where there is no power supply.

For this reason, in order to cool the apparatus in a relatively small size without using a power source, a heat exchanger 2 is installed on the bottom surface of the heat insulating container 1 as shown in FIG. It is known that a place 3 is provided.

The heat exchanger 2 is made of aluminum die-cast, and is provided with a passage 5 inside and a large number of fins 4 on the surface to increase a contact area with an ice block. The heat insulating container 1 is provided with a beverage supply port 6 and a drink outlet 7 with a cock.

[0005] The type of cooling with ice as described above is used as a simple beverage cooling device that does not require a power source, but since the heat exchanger 2 is made of aluminum die-cast, the entire weight is reduced. There is a problem that it becomes heavy, inconvenient to carry, and high in cost. As described above, when supplying a cold beverage such as draft beer at an event held outdoors or the like, it is desirable that the cooling device can be easily carried.

[0006] Therefore, an object of each invention of this application is to provide a beverage cooling device which is lightweight and easy to carry, and has a heat exchange efficiency comparable to that of the conventional one.

[0007]

In order to achieve the above-mentioned object, the invention according to claim 1 is such that the upper surface of a heat insulating container body is covered with a heat insulating lid so as to be openable and closable. The main body is provided with a beverage supply port and a beverage pouring port, the heat exchange pipe is stored inside the container main body by placing an ice lump storage space in the lower part and the upper part, and the inlet and the outlet of the heat exchange pipe are the beverage supply port. And the beverage pouring outlet are respectively connected via flexible joints.

In the beverage cooling device having the above structure, not only the heat exchange pipes contact the ice blocks stored in the upper and lower storage spaces, but also the heat exchange pipes melt the lower layer ice blocks as the heat exchange progresses. As it bites, the contact area with the ice mass increases.

According to a second aspect of the present invention, a heat-insulating container body is covered with a heat-insulating lid so as to be openable and closable, and the container body is connected to a beverage tank with a flexible beverage supply pipe and beverage pouring. A flexible joint pipe connected to the outlet is provided, and the heat exchange pipe is stored inside the container body with an ice lump storage space at the lower portion and the upper portion thereof, and the inlet and outlet of the heat exchange pipe are stored. The beverage supply pipe and the joint pipe are connected to each other.

The beverage cooling device having the above-described structure operates in the same manner as in the first aspect, but in this case the beverage supply pipe is directly connected to the inlet of the heat exchange pipe, so the number of parts is reduced.

According to the third aspect of the present invention, the inlet and the outlet of the heat exchange pipe are arranged at positions near one side wall of the container body.

In the beverage cooling device having the above-mentioned structure, the whole heat exchange pipe is bent upward at the joint portion, the ice mass is stored in the lower ice mass storage space of the container body, and then the heat exchange pipe is returned to the top thereof, Store the ice blocks in the upper ice block storage space above the exchange pipe. The heat exchange pipe gradually melts the ice block on the lower side by the width of the pipe and gradually enters the inside of the ice block to increase the contact area with the ice block.

According to a fourth aspect of the present invention, the heat exchange pipe includes an outward pipe extending from one wall of the container body to an opposite wall thereof, and an end pipe bent upward or downward and displaced by one pitch. To be a return pipe, and the same bending shape at the end of the return pipe is repeated from the inlet to the outlet, and flexibility is given to the bent portions at both ends of each forward pipe and return pipe. Is.

In this case, since the heat exchange pipe as a whole has flexibility due to the flexibility of the bent portions at both ends of the outward path and the return path of the heat exchange pipe, the heat exchange pipe has unevenness of ice blocks housed above and below it. It deforms to some extent according to the shape and increases the contact area with the ice blocks.

According to a fifth aspect of the present invention, an inclined plate is housed in the bottom surface of the container body, and the inclination direction of the inclined plate is lower on the outward pipe side connected to the inlet of the heat exchange pipe and connected to the outlet. The configuration is such that the return pipe is formed high.

The forward pipe connected to the inlet of the heat exchange pipe has the highest temperature, and the temperature gradually decreases as it approaches the outlet side. Therefore, the portion near the inlet most deeply melts the ice block. Therefore, the heat exchange pipe is inclined so that the front side of the container body is low and the rear side is high. Therefore, it is not necessary to store ice blocks evenly between the lower storage chambers. Therefore,
According to the invention of claim 5, the amount of ice on the rear surface side of the container body is reduced by the inclined plate on the bottom surface of the container body.

According to a sixth aspect of the present invention, a partition wall is provided inside one side wall of the container body, and notch portions are provided at front and rear ends of the partition wall, and the heat exchange is performed at one of the notch portions. A part of the outward pipe connected to the inlet of the pipe is fitted, and a part of the outward pipe also connected to the outlet is fitted to the other notch.

According to this structure, both ends (inlet and outlet) of the heat exchange pipe are fitted into the notches of the partition wall, so that the space between the both ends of the heat exchange pipe is kept constant, whereby the outward path can be maintained. The distance between the pipe and the return pipe can be kept constant.

[0019]

EXAMPLE As shown in FIG. 1, the beverage cooling apparatus of the first example (the example of the invention described in claims 1, 3 to 6) has a heat insulating container body 10 with a heat insulating lid 11 attached and detached. They are freely covered, and these are made by filling urethane foam 12 (see FIG. 3) between double walls made of synthetic resin.

A partition wall 14 parallel to the one side wall 13 of the container body 10 is provided at a position close to the side wall 13. The side wall 13
Is provided with a beverage supply port 15 (see FIGS. 2 and 3), and a front wall 16 near the side wall 13 thereof is provided with a drink pouring port 17 with a cock. Further, a drain port 18 (see FIG. 3) is provided below the side wall 13.

Inside the container body 10, in the space between the partition wall 14 and the side wall 13, flexible joint pipes 19 and 19 'connected to the beverage supply port 15 and the beverage spout 17 are housed. To be done.

Further, notches 21 and 21 'are provided at both front and rear ends of the partition wall 14. However, for the reasons described below,
The front notch 21 is deeply cut downward.

The bottom surface of the container body 10 accommodates an inclined plate 23 having a lower front wall 16 side and a higher rear wall 22 side.

The heat exchange pipe 24 housed on the inclined plate 23 has an inlet 25 and an outlet 26, and the inlet 2
5 is connected to the joint pipe 19 connected to the beverage supply port 15 and the outlet 26 is connected to the joint pipe 19 ′ connected to the beverage pouring port 17.

From the inlet 25, the heat exchange pipe 24 is
Forward pipe 28 extending to the other side wall 27 along the front wall 16
Other, it bends upward at a position close to the side wall 27 and shifts backward by one pitch to become a return pipe 29 parallel to the forward pipe 28. The return pipe 29 is downward at a position close to the partition wall 14. It bends and shifts backward by one pitch to become the next outward pipe 28. After that, this shape is repeated, and the final return pipe 29 is connected to the outlet 26.

The heat exchange pipe 24 is made of stainless steel, and its forward and backward pipes 28 and 29 are used.
The curved portion is flexible. Therefore, the heat exchange pipe 2
No. 4 is flexible as a whole because it is deformed in the horizontal direction or the vertical direction at the bent portion while maintaining the linearity of the outward pipe 28 and the return pipe 29.

Further, in order to keep the interval between the forward pipe 28 and the return pipe 29 constant, the inlet wall 25 and the outlet wall 26 of the heat exchange pipe 24 are separated from each other by the partition wall 14.
It is fitted in each of the notches 21 and 21 '. This allows
In the heat exchange pipe 24, the distance between the pipes 28 and 29 is kept constant.

In the state where the heat exchange pipe 24 is held in a horizontal state, a lower ice mass storage chamber space 31 is formed between the lower surface of the heat exchange pipe 24 and the inclined plate 23 (see FIG. 3).
An upper ice lump storage space 32 is formed between the upper surface of 4 and the lid 11.

The beverage cooling device of the embodiment is as described above. When using this, the lid 11 is removed and the heat exchange pipe 24 is bent upward at the joint pipes 19 and 19 '. Lifting (see the chain double-dashed line in FIG. 3), ice block 33 in the lower ice block storage space 31 on the inclined plate 23 (see FIG. 4)
Is put in, and the heat exchange pipe 24 is returned to the horizontal state on its upper surface. Furthermore, an ice block 33 is also placed in the upper ice block storage space 32 above it.
And put on the lid 11.

Further, as shown in FIG. 6, a gas cylinder 34
Beverage supply pipe 3
6 is connected to the beverage supply port 15 and the drain port 18
The drain hose 37 connected to is inserted into the bucket 38.

When the valve of the beverage tank 35 is opened and the cock of the beverage outlet 17 is opened, the pressurized beverage such as draft beer in the tank 35 is supplied with the beverage supply pipe 36, the inlet side joint pipe 19, and the heat exchange. It is poured out from the beverage outlet 17 through the pipe 24 and the outlet side joint pipe 19 ′.

At this time, the beverage passing through the heat exchange pipe 24 and the ice block 33 exchange heat with each other to cool the beverage. The relationship between the heat exchange pipe 24 and the ice lump 33 is initially such that the ice lump 33 is in contact with the upper and lower surfaces of the heat exchange pipe 24 as shown in FIG. 5A. As shown in (b), the ice blocks 33 below are melted by the widths of the pipes 28 and 29 and gradually eat into them. The amount of bite is 25 at the entrance.
The heat exchange pipes 24 gradually incline because there are a lot of those close to the outlet 26 and a lot of those near the outlet 26. In order not to prevent the inclination at this time, the front notch portion 21 is provided with the rear notch portion 2.
It is deeper than 1 '(see the chain double-dashed line in FIG. 4).

As the bite progresses, the contact area with the ice blocks further increases, so the heat exchange efficiency improves.

Since the heat exchange pipe 24 is inclined as described above, it is not necessary to store the ice blocks 33 up to the bottom surface of the container body 10 on the rear wall 22 side, and the inclined plate is used to save the amount of the ice blocks 33 used. I have entered 23. When the ice blocks 33 are excessive, it is safe to remove the inclined plate 23 and expand the lower ice block storage space 31.

Instead of the heat exchange pipe 24 of the above-mentioned embodiment, other heat exchange pipes having a zigzag shape in the two planes of the upper layer and the lower layer, that is, a zigzag shape in the plane of the upper layer and at the end thereof. It is possible to use one that bends and moves to the lower layer, and becomes zigzag in the plane of the lower layer. When the container body 10 has a cylindrical shape, it may have a spiral shape (single layer or upper and lower two layers).

Next, a second embodiment (claim 2) shown in FIG.
The embodiment of the invention described in (1) is the beverage supply pipe 36 described above.
Is drawn directly into the container body 1 and its tip is connected to the inlet 25 of the heat exchange pipe 24. Since the beverage supply pipe 36 also has flexibility, the inner portion of the container body 1 of the pipe 36 is the inlet side joint pipe 1 of the first embodiment.
Works the same as 9.

Since the other construction is the same as that of the first embodiment, the same parts are designated by the same reference numerals and the description thereof is omitted.

[0038]

Since the respective inventions of the present application are as described above, the invention according to claim 1 sandwiches the upper and lower sides of the heat exchange pipe with ice blocks, so that as the heat exchange progresses, the ice blocks in the lower part The heat exchange pipe bites into the inside, and the contact area between the two becomes large. Therefore, heat exchange efficiency equivalent to that of a conventional aluminum die-cast heat exchanger can be secured. Also,
Since the heat exchange pipe is significantly lighter than the aluminum die-cast heat exchanger, it is convenient to carry and the cost can be reduced.

The invention according to claim 2 has an advantage that the number of parts is reduced because the inlet side joint pipe can be omitted.

According to the third aspect of the invention, the ice mass can be stored in the lower ice mass storage space by bending the joint portion upward without removing the heat exchange pipe,
It is convenient.

According to the fourth aspect of the invention, since the entire heat exchange pipe is flexible, even if there is unevenness in the clogging of ice blocks, it deforms along the uneven shape. Therefore, the adhesion to the ice blocks is good, and the heat exchange efficiency is improved.

According to the fifth aspect of the present invention, the presence of the inclined plate makes it possible to save the amount of ice blocks used without hindering heat exchange.

According to the sixth aspect of the present invention, since the intervals between the heat exchange pipes are kept constant, it is possible to prevent a decrease in the contact area with the ice lumps, which is useful for improving the heat exchange efficiency.
