DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view from the front showing the structure of the cooling server of the present invention. Here, a description will be given by taking draft beer as a beverage and a beer barrel as a beverage container. The server body 1 of the cooling server has a substantially cylindrical shape, and a cylindrical cooling chamber 2 is formed inside the server body 1. The cooling chamber 2 is configured to be large enough to store the beer barrel 8. Further, the cooling chamber 2 is provided with a heat insulating material 13.
The lid 4 blocks the flow of heat from the outside air.

The cylindrical side wall 201 and the disk-shaped bottom surface 202 forming the cooling chamber 2 are integrally formed of stainless steel. The beer barrel 8 is stored by the positioning member 23 provided on the bottom surface 202 so as to be located at the center of the bottom surface 202. The diameter of the cylindrical server body 1 depends on the outer surface of the beer barrel 8 and the side wall 2 when the beer barrel 8 is stored.
01 and a space is created. It is sufficient that the distance between the outer surface of the beer barrel 8 and the side wall 201 is about 5 cm. The cooling body is stored in this space. Ice is most preferred as the cooling body in terms of cooling temperature, cooling efficiency and cost.

The base 81 of the beer barrel 8 projects out of the cooling server from the center hole of the lid 4. The dispensing head 7 is attached to the base 81.
The dispensing head 7 and the base 81 can be connected with one touch by a connection mechanism such as a bayonet mechanism. The dispense head 7 is a device for discharging draft beer inside the beer barrel 8 out of the container by the pressure of carbon dioxide gas.

A cooling pipe 3 is closely fixed to a side wall 201 of the cooling chamber 2 by continuous welding. Cooling pipe 3
Means that the inflow side connected to the dispense head 7 is the side wall 2
01, the pipe is spirally lowered from the top of the side wall 201, and then piped spirally on the bottom face 202 toward the center. The inflow side of the cooling pipe 3 is connected to a dispense head 7 directly or via a connection pipe, and the outflow side of the cooling pipe 3 is connected to the discharge cock 5 directly or via a connection pipe.

The cooling pipe 3 is a single pipe made of an aluminum alloy, stainless steel or the like, and cools draft beer while draft beer passes through the pipe. The cooling body cools draft beer through the cooling pipe 3 and also cools the container 8 directly to cool draft beer as a content. The pouring cock 5 is fixed so as to protrude from the outer surface of the server main body 1, and the beer is discharged from the pouring port 52 into a mug or the like by tilting the pouring lever 51 by hand.

A mini cylinder 6 of carbon dioxide gas is attached to the outer surface of the server body 1. From the mini cylinder 6, carbon dioxide gas is supplied to the dispense head 7 via a pressure reducing valve 61 and a gas supply pipe 62. Although the structure and function of the dispense head 7 will be described in detail later, when the opening / closing handle 73 is rotated around a vertical axis and lowered, the dispense head 7 supplies carbon dioxide gas into the beer barrel 8 and cools draft beer. It can flow out to the pipe 3 side. When the carbon dioxide gas is supplied from the dispense head 7 into the beer barrel 8, the pressure in the beer barrel 8 increases, and the draft beer is reduced to the down tube 83.
It is supplied to the cooling pipe 3 via the dispense head 7. Draft beer is cooled while passing through the cooling pipe 3 and is discharged from the discharge cock 5.

It is not always necessary to fix the bottom pipe 202 and the cooling pipe 3 and the portion near the bottom face of the side wall 201 and the cooling pipe 3 by continuous welding. As described above, since the side wall 201 and the cooling pipe 3 are closely adhered and fixed by continuous welding, not only direct heat transfer between the cooling body and the cooling pipe but also indirect heat transfer via the side wall can be used. . Therefore, the heat transfer efficiency is improved, and the cooling capacity is greatly increased.

FIG. 2 is a front sectional view showing the structure of the cooling server according to the second embodiment of the present invention. In the second embodiment, the server main body is vertically divided into an upper main body 11 and a lower main body 12. The upper main body 11 and the lower main body 12 are formed in a cylindrical shape having the same radius, and have a structure in which the engaging portions are fitted to each other, so that the engaged portions are not displaced from each other in the radial direction. The upper cooling chamber 21 inside the upper main body 11 and the lower cooling chamber 22 inside the lower main body 12 constitute one continuous cooling chamber when the upper main body 11 and the lower main body 12 are engaged. This cooling chamber is also shielded from heat from the outside air by the heat insulating material 13 and the lid 4.

The cooling pipe 3 is tightly fixed to the side wall 211 of the upper cooling chamber 21 by continuous welding. The cooling pipe 3 has an inflow side connected to the dispense head 7 disposed at an upper portion of the side wall 211, from which the side wall 21 is spirally formed.
1, the pipe is descended, and then spirally wound toward the center near the lowermost surface of the upper body. The space between the cooling pipes 3 is set such that a cooling body such as ice does not fall down. The cooling body is held and housed in a cooling pipe 3 arranged in a basket. Water formed by the melting of the ice of the cooling body and small pieces of ice fall down to the lower cooling chamber 2
The horizontal beer barrel 9 in 2 is directly cooled.

The inflow side of the cooling pipe 3 is connected to a dispense head 7 directly or via a connecting pipe, and the outflow side of the cooling pipe 3 is connected to the pouring cock 5 directly or via a connecting pipe. The pouring cock 5 is fixed so as to protrude from the outer surface of the upper main body 11.
Is to be poured into a mug or the like. A pocket 63 is fixed to the upper main body 11, and the mini cylinder 6 is stored in the pocket 63.

In the second embodiment, the dispense head 7 is attached to the upper main body 11. That is,
At the lower part of the upper cooling chamber 21 of the upper main body 11, a thin plate member 212 formed of a spring material or the like is arranged in a diametrically bridging manner, and both ends thereof are fixed to the upper side wall 211 by welding or the like. I have. The dispense head 7 is fixed at the center of the plate member 212, that is, at the center of the upper cooling chamber 21 so as to be aligned with the center axis of the upper cooling chamber 21.

FIG. 3 is a plan view of the cooling server according to the second embodiment as viewed from above, and shows the positional relationship between the plate member 212 and the dispense head 7. The vertical position and the inclination angle of the dispense head 7 can be displaced by a predetermined amount due to the elasticity of the plate member 212. For this reason, even if the base 81 of the horizontally long beer barrel 9 accommodated in the lower cooling chamber 22 and the dispense head 7 are not completely aligned, the dispense head 7 is displaced by a predetermined amount due to the elasticity of the plate member 212 and does not cause any trouble. Installation work can be performed. The mounting operation can be easily performed simply by mounting the upper main body 11 on the lower main body 12 with the phases of the bayonet mechanism and the like of the base 81 and the dispense head 7 and rotating the upper main body 11 rightward by a predetermined angle. .

On the bottom surface 222 of the lower cooling chamber 22, a horizontally long beer barrel 9 whose width is longer than its height is placed, and the whole container is stored in the cooling chamber. In the second embodiment, it is not necessary to provide a large space between the outer surface of the horizontally long beer barrel 9 and the lower side wall 221 of the lower cooling chamber 22. The horizontal beer barrel 9 is directly cooled by water or a small piece of ice formed by melting ice of a cooling body that falls down from between the cooling pipes 3, and is cooled by air in a cooling room cooled by the cooling body. Is also cooled.

FIG. 4 is an enlarged sectional view of the dispense head 7. FIG. 5 shows a beer barrel 8 and a horizontally long beer barrel 9.
It is an expanded sectional view near the base 81 of FIG. A mounting member 82 is screwed and fixed to the base 81 of the beer barrel 8 and the horizontally long beer barrel 9. The attachment member 82 has a down tube 83.
Are mounted by being urged upward by a coil spring. The down tube 83 has a lower end opened near the bottom of the beer barrels 8 and 9 and has a function of guiding draft beer pressurized by carbon dioxide gas to the dispense head 7. A beer valve 84 urged upward by a coil spring is provided inside the upper end of the down tube 83. A sealing material is fixed to the upper end of the down tube 83, and constitutes a gas valve for supplying and shutting off carbon dioxide gas into the beer barrels 8 and 9. At the same time, the seal material at the upper end of the down tube 83 and the beer valve 84 cooperate to supply and shut off draft beer.

By aligning the central axes of the dispense head 7 and the mounting member 82 and rotating the dispense head 7 around the central axis, the dispense head 7 and the mounting member 82 are airtight and liquid-tight by a connection mechanism such as a bayonet mechanism. Tightly connected. A hollow shaft 71 is provided at the center of the dispense head 7 so as to be vertically slidable. The hollow shaft 71 is urged upward by a coil spring. A cap 72 is attached to the upper end of the hollow shaft 71, and one end of the cooling pipe 3 is connected to the cap 72 directly or via a connection pipe.

Open / close handle 73 is connected to dispense head 7
Is rotated about the center axis of the dispensing head 7 by a cam mechanism or the like (not shown). When the opening / closing handle 73 descends, the hollow shaft 71 axially engaged with the opening / closing handle 73 also descends, and the tip of the hollow shaft 71 lowers the beer valve 84 against the spring force, and the down tube 83 Is lowered against the spring force.

Then, the gas valve and the beer valve 84 are opened, the carbon dioxide gas from the gas supply pipe 62 is supplied into the beer barrels 8 and 9, and the draft beer pressurized by the carbon dioxide gas is cooled by the cooling pipe 3. Can be spilled. When the opening / closing handle 73 is rotated in the opposite direction to return to the original position, the opening / closing handle 73 and the hollow shaft 71 are raised, the gas valve and the beer valve 84 are closed, and the supply of carbon dioxide gas and draft beer is shut off. .

The cooling pipe 3 may have a constant inner diameter from the inflow side connected to the dispense head 7 to the outflow side connected to the pouring cock 5. It is more preferable to change the inner diameter on the outflow side to two or several stages on the way so as to be smaller. Draft beer tends to foam when the temperature is high,
The flow rate must be reduced in order to suppress foaming. However, when the temperature is lowered, there is a characteristic that the foaming does not occur much even if the flow rate is increased.

Therefore, unnecessary foaming can be suppressed by increasing the inside diameter of the inflow side of the draft beer having a high temperature and decreasing the flow velocity. Also, by reducing the inner diameter of the cooling pipe 3 on the outflow side, the flow rate is squeezed and a flow rate adjusting action is produced. On the outflow side, the draft beer's flow rate increases, but no extra foaming occurs because it is cooled. Specifically, an inflow side pipe having an inner diameter of 5 mm and a length of 6 m and an outflow side pipe having an inner diameter of 4 mm and a length of 4 m are joined in the middle,
The cooling pipe 3 can be used. As a result, the uncooled draft beer at 30 ° C. was cooled to 7 ° C. or lower, and an appropriate flow rate and an appropriate discharge amount could be obtained without excessive foaming.

The vertical position and the inclination angle of the dispense head 7 can be displaced by a predetermined amount due to the elasticity of the plate member 212. For this reason, even if the base of the beer barrel 10 stored in the lower cooling chamber 22 and the dispense head 7 are not completely aligned, the dispense head 7
Is displaced by a predetermined amount due to the elasticity of the plate member 212, and the mounting operation can be performed without any trouble. The mounting operation can be easily performed simply by placing the upper main body 11 on the lower main body 12 with the phases of the base and the bayonet mechanism of the dispense head 7 matched, and rotating the upper main body 11 to the right by a predetermined angle.

The beer barrel 10 is placed on the bottom surface 222 of the lower cooling chamber 22. A positioning structure such as a concave portion, a convex portion, and a locking piece (not shown) is formed on the bottom surface 222, and positions the beer barrel 10 at the center of the bottom surface 222. The diameter of the cylindrical upper body 11 and lower body 12 is
In a state in which 0 is stored, a space is formed between the outer surface of the beer barrel 10 and the lower side wall 221 in which a cooling body can be stored. It is sufficient if the distance between the outer surface of the beer barrel 10 and the lower side wall 221 is about 5 cm. A cooling body is stored in this space, and the beer barrel 10 itself is cooled.

In the third embodiment, the beer barrel 10 is first pre-cooled in the lower cooling chamber 22 by a cooling body, and then the draft beer is completely cooled by the cooling pipe 3 at the time of pouring. Can be further improved, and even draft beer whose temperature has risen to about room temperature can be cooled to an appropriate temperature. Although the upper main body 11 and the lower main body 12 have a cylindrical shape with the same radius, any shape other than the cylindrical shape can be used as long as the engaging portions are rotationally symmetrical shapes that fit together.

FIG. 7 is a front sectional view showing the structure of the cooling server according to the fourth embodiment. In the fourth embodiment, the server main body is vertically divided into an upper main body 11 and a lower main body 12, as in the third embodiment. The inside of the upper body 11 constitutes an upper cooling chamber 21, and the inside of the lower body 12 constitutes a lower cooling chamber 22. The structure of the upper main body 11 and the lower main body 12 is substantially the same as that of the third embodiment.

A lining made of stainless steel or the like is provided on the inner surface of the upper body 11, and the lining goes around the bottom surface side to form the bottom surface 213 of the upper cooling chamber 21. Also,
The opening / closing handle 73 is provided at an upper position near the lid 4 to facilitate opening / closing operations. The feature of the fourth embodiment is the mounting structure of the dispense head 7. Other configurations are almost the same as those of the other embodiments, and thus detailed description is omitted.

FIG. 8 is a sectional view from the front showing only the upper body 11 of the cooling server. FIG. 9 is a bottom view of the upper main body 11 viewed from below. Upper cooling room 2
Below the bottom surface 213 of one, four vertical guide members 15 are fixed in a vertical state. As the vertical guide member 15, a thick bolt or the like can be used, which is fixed below the bottom surface 213 by welding, a nut or the like. The number of the vertical guide members 15 is not limited to four, and may be any number as long as it is three or more.

Holes are provided at four corners of the vertical moving plate member 14, and the vertical moving member 14 is inserted into the holes so that the vertical moving plate member 14 can be moved up and down and guided to the vertical guide member 15. Be attached. At this time, a coil spring 16 is arranged between the vertical moving plate member 14 and the bottom surface 213 to urge the vertical moving plate member 14 downward. The lower end position is restricted by a stopper nut 151 so that the vertical moving plate member 14 does not fall out of the vertical guide member 15.

The vertical moving plate member 14 is provided with a hole at the center thereof through which the lower part of the dispense head 7 is inserted. The dispense head 7 is fixed to the vertical moving plate member 14 by a fixing screw 17 so as to be located at the center position of the upper main body 11. The dispensing head 7 can be displaced by a predetermined amount in the vertical position and the inclination angle together with the vertical moving plate member 14 by the elasticity of the coil spring 16. Further, the displacement can be made larger than that of the third embodiment.

The vertical moving plate member 14 can be guided by the vertical guiding member 15 to have a vertical moving stroke of 10 mm or more, and even if the beer barrel 10 has an error of a height of about ± 5 mm. The dispensing head 7 can be mounted normally. As in the third embodiment, the upper body 11 is placed on the lower body 12 by adjusting the phases of the base and the bayonet mechanism of the dispense head 7 in the same manner as in the third embodiment, and the upper body 11 is turned rightward by a predetermined angle. It can be done simply by turning. When the upper body 11 is rotated, the dispense head 7 is also rotated via the vertical guide member 15 and the vertical moving plate member 14.

In the fourth embodiment, the vertical movement stroke of the dispense head 7 can be increased, so that one type of cooling server can handle various types of beer barrels. Even the beer barrels of the same standard have a variation of about ± 5 mm depending on the manufacturer and the type of the barrel, but the cooling server according to the fourth embodiment can cope with such a height error. It is.

As described above, the cooling server of the present invention accommodates a beer barrel in the cooling chamber, cools draft beer flowing out of the beer barrel through the cooling pipe by the cooling body, and also cools the beer barrel itself. Cooling by air cooled by body and cooling body. Therefore, the cooling capacity of draft beer is improved, and the consumption of the cooling body is also reduced.

The appropriate pressure of the carbon dioxide gas for discharging the draft beer is determined by the temperature of the draft beer. The appropriate pressure decreases as the temperature of the draft beer decreases. Therefore, the pressure reducing valve 61 is adjusted to adjust the carbon dioxide gas pressure to about 3.
And 0 kg / cm ^2, beer barrel temperature of about 1.5 kg / cm ² of carbon dioxide gas pressure if 15 ° C.. That is, by cooling the beer barrel, the carbon dioxide gas pressure can be reduced, and the carbon dioxide gas consumption is reduced. These points reduce running costs.

Further, the cooling server of the present invention accommodates beer barrels in the cooling chamber, and thus is optimal for small-volume beer barrels of about 5 liters. There is no need for a power supply or the like, nor is it necessary to cool the beer barrel in advance. It is stable even on slopes. For this reason, it can be used for a wide range of uses such as evening drinks at home, home parties, camping, and group customers at restaurants. In addition, since stainless steel beer barrels can be used as many times as they are washed, the cost of recycling is reduced compared to conventional bottles and cans made of glass, aluminum, etc., which is also effective in saving resources. .

In the above embodiment, draft beer is taken as an example of a beverage, but the invention can be applied to any other beverage.

[0051]

Since the present invention is configured as described above, it has the following effects.

Since the beverage container is housed in the cooling chamber, the whole container is cooled and the cooling capacity is improved. Even in a small-capacity beverage container, the overall stability is large and it is difficult to collapse. Also,
The amount of use of the cooling body and the gas for dispensing the beverage can be reduced, and the running cost is reduced.

By storing the cooling body in the space between the side wall of the cooling chamber and the outer surface of the beverage container, the cooling body can simultaneously cool the cooling pipe and the beverage container powerfully, thereby cooling the beverage. The ability is further improved.

Since the cooling pipe and the side wall of the cooling chamber are joined by continuous welding, not only direct heat transfer between the cooling body and the cooling pipe but also indirect heat transfer through the side wall can be utilized. . Therefore, the heat transfer efficiency is improved, and the cooling capacity is greatly increased.

Since the server body is divided into upper and lower parts, simply placing the upper body on the lower body and rotating it,
The mounting work of the dispense head is completed, and the mounting work can be easily performed. Further, since the beverage container can be completely stored in the cooling server, the heat retention is improved.

Since the dispensing head is fixed to the elastic plate member, the dispensing head can be mounted without trouble even if the cap of the beverage container and the dispensing head are not perfectly aligned.

Unnecessary foaming can be suppressed by increasing the inside diameter of the cooling pipe on the inflow side where the draft beer has a high temperature and decreasing the flow velocity. Also, by reducing the inner diameter of the cooling pipe on the outflow side, the flow rate is reduced and a flow rate adjusting action is produced.

By pre-cooling the entire beverage container in the lower cooling chamber before the main cooling of the beverage in the upper cooling chamber, the cooling capacity of the entire cooling server is further improved.

Since the vertical movement stroke of the dispense head can be increased, one type of cooling server can cope with various types of beer barrels having variations in height.
