Added. As a result, the cooling plate 15 is cooled by the Peltier module 23, and when the cooling plate 15 is cooled below the set temperature, the bimetal thermo 38 is cut off and the supply of voltage to the Peltier module 23 is stopped.
Further, when the battery 41 is used, the same effect as that after rectification by the bridge diode 43 when the commercial power source 40 is used is obtained.
[0012]
1 and 2 again, a cover 13 is attached to the upper surface side of the main body 12 of the above-described cooler 11. The cover 13 functions to cover the outer periphery of the base 3a of the dispenser 3 provided in the barrel-shaped container 1, and is formed by filling foamed urethane in the outer shell body made of hard resin, like the heat insulating case 14. ing. The cover 13 has a shape in which a cover plate 48 is formed on the upper surface of a short cylindrical portion 47 and an escape hole 49 is provided in the cover plate 48, and is divided into two so as to be attachable from the side. Specifically, the two cover components 13a divided into two are connected by a hinge 50 so as to be opened and closed, and a hook lock 51 is provided on each free end side. As shown in FIG. 7A, the hook lock 51 is constituted by a locking ring 52 provided at one free end of the cover structure 13a and a holding piece 53 provided at the other free end. By holding the retaining ring 52 on the restraining piece 53 and restraining the restraining piece 53 against the spring elasticity, the two free ends are held in a combined state as shown in FIG. It has become.
Moreover, between the heat insulation case 14 of the main body 12 and the cover 13, the same hook lock 51 for hold | maintaining them in a coupling | bonding state is provided in two sets symmetrical position.
[0013]
The first embodiment has the structure as described above. Next, a method of using the structure will be described.
First, the barrel-shaped container 1 cooled to an appropriate temperature by a refrigerator or the like is inserted into the main body 12 of the cooler 11. Subsequently, the opened cover 13 is attached from the side around the base portion 3a of the dispenser 3, and the hook lock 51 is stopped to join the both cover components 13a. At the same time, two sets of hook locks 51 provided between the cover 13 and the main body 12 are stopped, and both are coupled. Thereby, as shown in FIGS. 3 and 4, the barrel-shaped container 1 is accommodated in the cooler 11 from the main body 2 to the base 3 a of the dispenser 3, and in particular, the main body 2 is fitted just inside the cooling plate 15. Become.
[0014]
In this state, when the electronic cooling device 17 is connected to the commercial power supply 40 or the battery 41, the motor 44 is started and the radiating fan 20 rotates as described above, and a DC voltage is supplied to the Peltier module 23. Then, heat transfer from the inner heat absorbing surface 23a to the outer heat radiating surface 23b occurs due to the Peltier effect, the cooling plate 15 is cooled via the heat absorbing side heat conductor 24, and the inside of the barrel-shaped container 1 stored therein The draft beer is cooled. At that time, the heat transferred to the heat radiation side heat conductor 25 is sequentially dissipated by the heat radiation fins 19 and the heat radiation fan 20 as shown by arrows in FIGS. Further, since the electronic cooler 18 is applied to the upper side of the cooling plate 15, the upper part is quickly cooled, but the whole of the barrel-shaped container 1 is cooled evenly by the cold air being sequentially flowed downward by natural convection. . When the cooling plate 15 is cooled below the set temperature, the bimetal thermo 38 is cut off, the supply of voltage to the Peltier module 23 is stopped, and the draft beer in the barrel-shaped container 1 is cooled and stored at an appropriate temperature by repeating the operation.
And when pouring the draft beer in the barrel-shaped container 1, the draft beer cooled well can be poured by operating the extraction cock 4 with the barrel-shaped container 1 being accommodated in the cooler 11. it can.

As described above, according to the first embodiment, since the cooling plate 15 can be continuously cooled by the electronic cooling device 17, the draft beer in the barrel-shaped container 1 can be cooled and stored at an appropriate temperature for a long time. In addition, since both the commercial power source 40 and the vehicle battery 41 can be used, they can be used in various places. In addition, it is convenient that the draft beer can be poured out without removing the barrel-shaped container 1 from the cooler 11 one by one.
[0016]
Further, since the cooling load is reduced as a structure in which the main body 2 of the barrel-shaped container 1 is accommodated immediately inside the cooling plate 15, a sufficient cooling effect can be obtained even with a Peltier module 23 having a relatively small cooling capacity. In addition, since the cover 13 is divided into two, the cover 13 can be mounted even after the dispenser 3 is attached to the barrel-shaped container 1, and it is excellent in usability. Furthermore, by adopting a structure in which the electronic cooler 18 is placed on the upper side of the cooling plate 15, the entire barrel-shaped container 1 can be evenly cooled using natural convection of cold air.
