The refrigerator 10 is a heat insulating refrigerator main body 11 having a vertically long box shape with a front opening, and one vertical edge (for example, right edge) of the front opening 12 of the refrigerator main body 11 that is swingably opened and closed. It is composed of a heat insulating door 13.

As shown in FIG. 9, a vertically long cooling duct 18 having a substantially trapezoidal cross section is formed at a corner on the left side of the refrigerator main body 11 on the left side when viewed from the front by a duct panel 17 extending vertically. Therefore, the area on the near side of the cooling duct 18 in the refrigerator main body 11 is a refrigerator compartment 15 in which the beer barrel B described above is stored. In this example, as shown in FIGS. 5 and 6, a maximum of four beer barrels B can be stored in the form of being stacked in two tiers in each region on the right back side and the left front side in a front view. Yes.

The machine room 30 arranged on the lower surface of the refrigerator 10 is formed in a flat box shape whose peripheral surface shape substantially follows the peripheral surface shape of the refrigerator 10 described above. Although not shown in detail in the machine room 30, a refrigeration apparatus comprising a compressor, an air-cooled condenser, etc., an electrical box, etc. are housed, and

casters

31, 32 are provided on the bottom surface of the machine room 30. It is provided and is movable, that is, portable.

The duct panel 17 constituting the inner surface of the cooling duct 18 is formed with a suction port 20 for air inside the cabinet, and a cold air outlet 21 is formed at the upper end. .
In the cooling duct 18, a cooler 23 (evaporator) is installed at a position between the air outlet 21 and the suction port 20 described above. The cooler 23 is circulated and connected to a refrigeration apparatus installed in the machine room 30 through a refrigerant pipe, thereby forming a known refrigeration circuit.
A cooling fan 25 composed of a fan motor is provided on the back side of the air outlet 21. Here, as shown in FIG. 6, the cooling fan 25 is at a height corresponding to the region of the ceiling portion 15 A above the beer barrel B packed in two stages, and the rotation center axis thereof is as shown in FIG. 5 and FIG. As shown in FIG. 9, it is directed near the center of the refrigerator compartment 15.
The cold air supply apparatus of the present invention is configured as described above.

Therefore, when the refrigeration apparatus and the cooling fan 25 are driven, the internal air is sucked in from the suction port 20 and flows upward in the cooling duct 18 to exchange heat with the cooler 23 to generate cold air. The cold air is blown out from the outlet 21 to the ceiling portion 15A of the refrigerator compartment 15 in the direction along the rotation center axis of the cooling fan 25 and is circulated and circulated in the refrigerator compartment 15.
A drain pan 26 that receives defrosted water from the cooler 23 is disposed on the bottom surface of the cooling duct 18.

On the upper surface of the beer barrel B, as shown in FIG. 6, a connection port B1 of a beer pressure hose 35 (beer hose 35) and a gas supply hose (gas hose) drawn from a gas cylinder G (see FIG. 5). Connection port B2 (not shown).
As will be described in detail later, the beer hose 35 connected to the connection port B1 of the beer barrel B to be poured is poured with an opening / closing cock 53 provided in the pouring part 40 constructed on the upper surface of the refrigerator 10. Connected to the outlet 52.

On the other hand, the gas cylinder G is accommodated in the holder 37 in a posture of lying down in the front-rear direction, as shown in FIG. 5, at a substantially central position of the depth at the upper end of the right side surface of the refrigerator compartment 15. Here, the lower corner of the inner side of the holder 37 is an R surface 38, and the cold air blown out from the outlet 21 of the cooling duct 18 hits the R surface 38 of the holder 37. As shown by the line a, it is guided in the direction of flowing down along the right side surface. That is, the R surface 38 is a wind direction surface.
When the gas hose of the gas cylinder G is connected to the connection port B2, carbon dioxide gas is supplied. When the cock 53 is opened, the cooled beer in the beer barrel B reduces the pressure of carbon dioxide gas. In response to this, it is poured out from the spout 52 of the pouring section 40.

The structure of the extraction part 40 will be described with reference to FIGS. On the upper surface of the refrigerator main body 11, a mounting stage 41 having a plane shape substantially the same as that of the refrigerator 10 (including the door 13) is installed. Accordingly, the edge on the near side of the mounting stage 41 is arranged so as to cover the upper side of the closed door 13. A center hole 42 having an oblong cross section elongated in the front-rear direction is opened in the mounting stage 41, and an annular drain pan 43 that is one step lower is formed around the center hole 42. A grill 45 that has a central hole 46 that is slightly smaller than the central hole 42 and is divided into two in the front-rear direction is attached to the upper surface opening of the drain pan 43. A plurality of through holes 47 are formed in the grill 45, and a spacer 48 that receives the grill 45 is formed on the bottom surface of the drain pan 43. A discharge port 49 is formed at a front edge of the bottom surface of the drain pan 43, that is, a portion protruding to the front side of the front opening 12 of the refrigerator main body 11, and is always closed with a cap 49A.
As will be described later, when beer overflowing from a container such as a mug spills on the grill 45, the beer is dropped onto the drain pan 43 through the through-hole 47 of the grill 45, and can be discharged from the discharge port 49 by removing the cap 49A. It has become.

A pouring tower 50 stands up and is installed at the center of the mounting stage 41. The pouring tower 50 is formed in a cylindrical shape having an oblong cross section elongated in the front-rear direction. The upper surface of the pouring tower 50 is closed by a cover 51 and is disposed on the front surface of the upper end portion of the pouring tower 50. The spout 52 with the opening / closing cock 53 is mounted so as to protrude to the front side. Although not shown in detail, screw receivers with screw holes are formed at the four corner positions on the inner peripheral surface of the lower end portion of the pouring tower 50 so as to protrude.
The lower end surface of the pouring tower 50 is placed on the hole edge portion 42A of the center hole 42 in the placement stage 41 via the spacer 55, and is fastened together by a bolt 58 for attaching a cooling tool 60 described later. .
In the ceiling wall 15B of the refrigerator compartment 15, a window hole 16 having an oval cross section aligned with the center hole 42 is formed through the top and bottom surfaces immediately below the center hole 42 of the mounting stage 41. .

Now, means are provided in the pouring tower 50 to cool around the beer hose 35 that stands up in the pouring tower 50 and is piped. Therefore, a cooling tool 60 as shown in FIG. 7 is prepared. The cooling tool 60 includes a pipe 61 and a cold heat collecting plate 62 made of a metal having excellent heat conductivity such as aluminum.
The pipe 61 is a circular pipe through which the above-described beer hose 35 can be inserted with a clearance. As shown in FIG. 6, the pipe 61 is attached to the pouring tower 50 from the lower end surface of the window hole 16 of the ceiling wall 15B. It has a height dimension that reaches the vicinity of the outlet 52.
The cold heat collecting plate 62 is formed in a rectangular shape that is slightly long in the front-rear direction and can cover the lower surface opening of the window hole 16 of the ceiling wall 15B, and the mounting hole 63 in which the lower end of the pipe 61 is tightly fitted in the center. Are opened, and through holes 64 for bolts 58 are formed at the four corners.

The cooling tool 60 is formed by fitting the lower end of the pipe 61 into the mounting hole 63 of the cold heat collecting plate 62 so as to be flush with the lower surface and fixing by welding or the like.
In this cooling tool 60, after the pipe 61 is inserted into the pouring tower 50 from the window hole 16 of the ceiling wall 15B and the cold heat collecting plate 62 is applied to cover the lower surface opening of the window hole 16 of the ceiling wall 15B, Bolts 58 are passed through the insertion holes 64, pass through the window holes 16 and the edge of the center hole 42 of the mounting stage 41, and then provided from the insertion hole 56 of the spacer 55 to the inner periphery of the lower end of the pouring tower 50. It is fixed by screwing into the four screw holes (not shown). At the same time, the pouring tower 50 is also fixed.
As described above, the cold heat collecting plate 62 is stretched on the lower surface of the ceiling wall 15B where the window hole 16 is opened, and the pipe 61 integrally coupled with the cold heat collecting plate 62 is formed at the center of the pouring tower 50. It will be in the state where it stood and arranged near the attachment position of spout 52. Further, as shown in FIG. 9, the vicinity of the center of the cold heat collecting plate 62 is located on an extension line in the axial direction of the cooling fan 25 (cooling air blowing direction).

Then, one end of the beer hose 35 is connected to the spout 52, the other end of the hose 35 is passed downward through the pipe 61, and the other end hangs down into the ceiling portion 15A of the refrigerator compartment 15, It can be connected to the connection port B1 of the barrel B.
A heat insulating material 70 is attached from the inside of the pouring tower 50 to the center hole 42 of the mounting stage 41 and the inside of the window hole 16 of the ceiling wall 15B so as to cover the periphery of the pipe 61. A heat insulating material 71 is also attached to the upper end portion of the tower 50.
Both heat insulating

materials

70 and 71 are formed in advance in a predetermined shape from polypropylene. As shown in FIGS. 3 and 6, the heat insulating material 70 has a large-diameter portion whose upper side fits tightly into the pouring tower 50, and a lower end portion of the ceiling wall 15 B from the center hole 42 of the mounting stage 41. The stepped shape is a small-diameter portion that fits tightly across the window hole 16, and the center hole 70A through which the pipe 61 of the cooling tool 60 is inserted is formed over the entire height. The heat insulating material 71 has a thick plate shape.

The reason why the

heat insulating materials

70 and 71 are not separately foam-filled but formed as a separate body and attached later is to make the pouring tower 50 detachable. If the bolt 58 is removed from the state shown in FIG. 8 and the cooling tool 60 is pulled into the refrigerator compartment 15, the pouring tower 50 can be pulled out together with the

heat insulating materials

70 and 71 and removed. When the extraction tower 50 can be removed in this way, when transporting a beer dispenser as a product, the product size can be lowered by the amount of the extraction tower 50, so that the transportation cost can be reduced. Further, it is possible to avoid damage caused by contact of foreign matter with the pouring tower 50 during transportation. Furthermore, since the removed extraction tower 50 should just be accommodated in the refrigerator 10 at the time of transport, it is not necessary to carry the extraction tower 50 separately.
When assembling after carrying in, the small diameter part of the heat insulating material 70 protruding from the lower surface of the pouring tower 50 is fitted over the window hole 16 of the ceiling wall 15B from the central hole 42 of the mounting stage 41, and the pouring tower 50. It is only necessary to place the lower end of the upper end on the hole edge portion 42A of the center hole 42, and then push the cooling tool 60 in from the refrigerator compartment 15 side, and finally fix it with the bolts 58, so that assembly work on site can be facilitated. In the state where the pouring tower 50 is assembled, the heat insulating material 70 has a stepped shape, so that the cold air in the refrigerator compartment 15 is hardly leaked.

The beer dispenser of the present embodiment has the above-described structure, and subsequently an example of use will be described.
The door 13 is opened, and up to four beer barrels B are stored in the refrigerator compartment 15, and the gas cylinder G is stored in the holder 37. The lower end of the beer hose 35 hanging down in the refrigerator compartment 15 is connected to the connection port B1 of one beer barrel B, and the gas hose drawn from the gas cylinder G is connected to the connection port B2 of the beer barrel B. Carbon dioxide is supplied into the beer barrel B. The beer in the beer barrel B is in a state of being pumped to the spout 52 through the beer hose 35. When the pipe connection as described above is finished, the door 13 is closed.

When the cooling operation is started in this state, that is, when the refrigeration apparatus and the cooling fan 25 are operated, the internal air is sucked in from the suction port 20 provided in the lower end portion and flows upward in the cooling duct 18. Then, cold air is generated by exchanging heat with the cooler 23, and the cold air is blown out from the air outlet 21 in a direction along the rotation center axis of the cooling fan 25.
As shown by an arrow a in FIG. 5, the cold air is basically blown out toward the upper position of the right side surface facing through the ceiling 15 A of the refrigerator compartment 15, and the gas cylinder G disposed at the same position is blown out. A circulating flow is generated such that it is guided by the R surface 38 of the holder 37 and directed downward, and subsequently sucked from the suction port 20 at the lower end of the cooling duct 18. Along with this, as shown by the arrow b in FIG. 6, the beer barrel B, that is, the beer inside thereof, is circulated around the beer barrel B in which cold air is stored.

In the meantime, as shown in FIG. 8, a part of the cold air blown out from the outlet 21 flows while hitting the cold heat collecting plate 62 of the cooling tool 60, thereby cooling the cold heat collecting plate 62. As shown by the line c, the cold heat is conducted to the pipe 61 to be cooled, and the beer hose 35 inserted into the pipe 61 is cooled by the radiant heat and the beer waiting in the beer hose 35 is also cooled. To be cooled.
When the blown cold air hits the cold heat collecting plate 62, it tries to enter the pipe 61, but the beer hose 35 is inserted into the pipe 61, so that there is a slight clearance. In addition, the amount of cold air entering the pipe 61 is minimized, in other words, there is almost no decrease in the amount of cold air circulated and supplied into the refrigerator compartment 15, and the cooling rate in the refrigerator compartment 15 is not reduced. .

For example, in the case where 40 L (liter) of water stored in the refrigerator compartment 15 is cooled from 25 ° C. to 2 ° C., this embodiment is compared with the case where cold air is positively introduced into the conventional pouring tower. It was confirmed that the cooling time was reduced by about 30 minutes.
Further, the beer hose 35 is passed through the small-diameter pipe 61 in the cooling device 60, and the thick

heat insulating materials

70 and 71 can be attached around the pipe 61. As a result, the beer hose 35 can be hardly affected by external heat. Thus, it is effective to maintain the inside of the pipe 61 in a cooling atmosphere. In the present embodiment, the temperature in the pipe 61 can be maintained near 0 ° C.

When pouring beer, placing a container such as a mug on the grill 45 and opening the cock 53 of the spout 52, the beer cooled in the predetermined beer barrel B receives the pressure of carbon dioxide and receives the beer hose. 35 is pumped and poured out from the spout 52 into the container. During this time, as described above, the beer hose 35 inserted into the pouring tower 50 is cooled by the cold heat of the surrounding pipe 61, so that the temperature of the beer is prevented from rising while circulating the beer hose 35. The
When the beer barrel B that has been poured out becomes empty, the beer hose 35 and the gas hose are removed from the beer barrel B, and replaced with another beer barrel B that has been stored before. If necessary, the beer barrel B that has been emptied and the new beer barrel B are exchanged and stored.

During the above-described pouring or the like, beer overflowing from a container such as a mug is dropped and collected in the drain pan 43 through the through hole 47 of the grill 45. When discharging the accumulated beer, after opening the door 13, a drain container such as a bucket is arranged below the discharge port 49 provided at the front side of the drain pan 43, and the cap 49A is removed and discharged. What is necessary is just to discharge | emit to the drain container from the exit 49. FIG.
Since the discharge port 49 is provided in the portion of the mounting stage 41 (drain pan 43) that protrudes from the upper portion of the door 13, the discharge operation can be easily performed in view of attaching the drain container or removing the cap 49A. Further, since the discharge port 49 is provided at a position hidden by the closed door 13, there is no possibility that the aesthetic appearance is impaired for the user.

As described above, in the beer dispenser of the present embodiment, when cold air is circulated and supplied to cool the beer barrel B in the refrigerator compartment 15, a part thereof contacts the cold heat collecting plate 62 of the cooling tool 60. The cold heat collecting plate 62 is cooled, and the cold heat is conducted to the pipe 61 to be cooled, and the beer hose 35 inserted into the pipe 61 is cooled by radiant heat, and waits in the beer hose 35 before pouring. It is possible to prevent the temperature of the beer that is being circulated and the beer that circulates in the beer hose 35 at the time of pouring.
Since the beer hose 35 can be cooled by heat conduction without introducing cool air into the pouring tower 50, the air volume of the cool air that is circulated into the refrigerator compartment 15 is not reduced, and the beer barrel B is cooled. A reduction in speed is prevented. In particular, since the relatively cool air after heat exchange with the cooler 23 comes into contact with the cold heat collecting plate 62 of the cooling tool 60, the pipe 61 is more easily cooled. Further, since a thick layer of

heat insulating materials

70 and 71 can be secured around the pipe 61, it is hardly affected by external heat.
As a result, the surroundings of the hose in the pouring tower 50 can be efficiently cooled without causing a decrease in the cooling rate of the refrigerator compartment 15.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS.
In the second embodiment, the structure of the cooling tool 60A is changed. That is, the dimension of the pipe 61A is longer than the pipe 61 of the first embodiment by a predetermined length, and after the pipe 61A is fitted in the mounting hole 63 of the cold heat collecting plate 62, the lower end portion 65 becomes longer. They are integrally coupled in such a manner as to protrude to the lower surface side of the cold heat collecting plate 62.
Therefore, when the cooling tool 60A is fixed by being applied to the ceiling wall 15B of the refrigerator compartment 15, the predetermined length portion of the lower end portion 65 of the pipe 61A is on the lower surface side of the cold heat collecting plate 62, that is, the ceiling portion 15A of the refrigerator compartment 15. It becomes a form protruding.
About another structure, it is the same as that of the said Embodiment 1, Comprising: The duplicate description is abbreviate | omitted by attaching | subjecting the same code | symbol about the member and site | part which have the same function as Embodiment 1. FIG.

In the second embodiment, a part of the cold air blown out from the air outlet 21 hits the cold heat collecting plate 62 of the cooling tool 60A and also hits the protruding lower end portion 65 of the pipe 61A. This further promotes cooling of the pipe 61A.

<Embodiment 3>
13 and 14 show Embodiment 3 of the present invention. In the cooling tool 60B of the third embodiment, a wind direction plate 67 made of a metal plate that is also excellent in thermal conductivity, such as aluminum, is integrally fixed to the cold heat collecting plate 62 of the cooling tool 60 illustrated in the first embodiment. Has been. Specifically, the wind direction plate 67 is disposed in an oblique posture with the lower end protruding toward the front side at a position on the front side of the mounting hole 63, and is fixed by welding or the like. The lower end of the wind direction plate 67 is directed, for example, near the center of the upper surface of the upper beer barrel B stacked on the front side.

In the third embodiment, by providing the wind direction plate 67, the contact area with the cold air blown out from the outlet 21 is expanded, and the collection of cold heat is promoted. Further, as shown by the arrow d in FIG. 14, the cold air hitting the wind direction plate 67 is directed to the upper surface of the beer barrel B along the wind direction plate 67, that is, storing the beer barrel B in the refrigerator compartment 15. It can be circulated in the region and efficiently applied to the beer barrel B, and the cooling rate in the refrigerator compartment 15 can be increased.

<Embodiment 4>

In addition, a spout 52 is mounted at the opening position of the upper bent portion 84 of the pipe 82 on the side surface of the spout tower 80, and the beer hose 35 connected to the spout 52 is inserted into the pipe 82 and stored in the refrigerator compartment 15. Is pulled out to the ceiling portion 15A of the beer barrel B and can be connected to the connection port B1 of the beer barrel B.

In the beer dispenser of this embodiment, when cold air is circulated and supplied to cool the beer barrel B in the refrigerator compartment 15, a part of the cold air is brought into contact with the cold heat collecting plate 86 of the cooling tool 81, so 86 is cooled, the cold heat is transferred to the pipe 82 and cooled, the beer hose 35 inserted into the pipe 82 is cooled by radiant heat, and the beer that is waiting in the beer hose 35 before pouring The temperature of beer flowing through the beer hose 35 at the time of pouring is prevented from rising.
Since the beer hose 35 can be cooled by heat conduction without introducing cool air into the pouring tower 80, the air volume of the cool air that is sent to the refrigerating room 15 does not decrease, and the beer barrel B is cooled. A reduction in speed is prevented. Further, since a thick layer of heat insulating material 90 can be secured around the pipe 82, it is not easily affected by external heat. As a result, the periphery of the hose 35 in the pouring tower 80 can be efficiently cooled without causing a decrease in the cooling rate of the refrigerator compartment 15.

As a modification of the fourth embodiment, the arrangement position of the pouring tower 80 may be raised from another peripheral surface such as the back surface of the refrigerator main body 11.
Further, the height position of the extraction tower 80 that communicates with the refrigerator compartment 15 may be set to an arbitrary height position on the peripheral wall of the refrigerator compartment 15.
