Moreover, the small refrigerator R includes an assembly of the upper frame 14 and the lid 15 which are assembled in advance to form a unit,
By using the refrigerating unit U and the beverage container take-out control member C, it can be manufactured with excellent work efficiency.

Next, the operation of the embodiment of the small refrigerator for in-vehicle sales of the present invention having the above-mentioned structure will be described. The small refrigerator mounting plate B1 mounted on the rear surface of the backrest A1
The small refrigerator R mounted on the socket 21g is always supplied with power to the socket 21g by a power supply cable (not shown). In this case, the solenoid 29, which operates only when a predetermined amount of coins are inserted, is always off and does not operate. At this time, the retractable locking member 29a of the solenoid 29 is held at the projecting position by a spring (not shown) of the solenoid 29 to prohibit the left end slide plate 25 from moving to the left. In this case, the opening 28 cannot expand. Therefore, even if the passenger of the taxi illegally tries to take out the soft drink from the small refrigerator R without inserting a coin, the soft drink is caught in the opening 28 and cannot be taken out.

However, while power is supplied to the small refrigerator R, the Peltier element 34 and the fan 31 are constantly operating. At this time, the cooling air is sequentially supplied by the operation of the fan 31, and the suction port R1 and the heat exchange fin 32a are sequentially supplied.
The surface flows through the discharge port R2. At that time, the heat of the refrigerating container 33 is transferred from the Peltier element 34 to the heat dissipation member 3
2 is connected to the connecting plate 32b and the plurality of heat exchange fins 32a. The heat conducted to the heat dissipation member 32 is exchanged with the cooling air blown from the suction port R1 by the fan 31. The air whose temperature has risen due to this heat exchange is discharged from the discharge port R2. The refrigerating container 33 is cooled by continuously performing the heat exchange.

Therefore, if a beverage container containing a soft drink is stored in the refrigerating container 33, the soft drink is always kept cold. When a taxi passenger inserts three 100 coins from the coin slot 43 (FIGS. 1, 3 and 11), a sensor (not shown) detects that three 100-yen coins have been inserted, and the take-out permission signal is output. Occurs. Then, the solenoid 29 operates to move the retractable locking member 29a to the retracted position (in FIG. 10,
Move downward). In this state, the opening 28 can be expanded. Therefore, when the passenger lifts the lid 15 supported by the upper frame 14 and pulls out the soft drink stored in the refrigerating container 33, the opening 28 expands, so that the cold soft drink can be taken out.

Although one embodiment of the small refrigerator for in-vehicle sales according to the present invention has been described in detail above, the present invention is not limited to the above embodiment, and deviates from the invention described in the claims. It is possible to make various small design changes without doing so.

For example, the lid 15 of the small refrigerator R can be automatically opened and closed. In that case, the lid 15 can be kept closed at all times, and the lid 15 can be opened only when a coin is inserted. Further, the arrangement position of the small refrigerator R in the vehicle is
It can also be placed in the rear tray behind the rear seats. In that case, passengers may not be aware that they are selling soft drinks in the car, so by providing an in-vehicle announcement device, it is voiced that a small refrigerator R for soft drinks vending is installed in the rear tray. It can also be configured to notify. Further, the take-out permission signal for actuating the solenoid 29 to move the retractable locking member 29a to the retracted position is not generated when a predetermined amount of coins are inserted, but according to the passenger's order. It is also possible for the driver to press the take-out permission signal generation button provided at his / her side. In this case, since the inserted coin processing space S2 can be omitted, the small refrigerator R can be further downsized, and the space S can be further reduced.
Since it is possible to omit the commercially available coin processing device to be assembled in 2, it is possible to save the manufacturing cost of the small refrigerator R.

Further, a solenoid 29 is used as a slide amount control member that allows the slide plates to slide when the take-out allowance signal is generated and allows the space between the adjacent slide plates to widen. Instead, it is also possible to employ a member that moves back and forth by a motor. And the small refrigerator R of the present invention
It is also possible to form the outer surface of the refrigerating container 33 shown in FIG. In this case, since the inner surface of the heat insulating material 35 can be formed into a flat shape, the manufacturing cost of the heat insulating material 35 can be saved. And further,
It is also possible to combine the heat dissipation member 32 and the fan 31 of the refrigeration unit U with a screw or the like to form a unit. In this case, the front wall member 11 and the rear wall member 1 of the small refrigerator R
Since all the constituent elements arranged in the refrigerating container / heat radiating member accommodation space S1 inside 2 can be made into one unit, the working efficiency of the assembling process is improved.

INDUSTRIAL APPLICABILITY The above-mentioned small refrigerator for in-vehicle sales of the present invention normally prohibits the taking out of the beverage container, but allows the taking out of the beverage container when necessary (when the take-out permission signal is generated). The container take-out control member prohibits the slide (movement) of the slide plate at all times and the guide plate, a plurality of slide plates slidably supported by the guide plate, and when necessary (take-out permission signal is generated). In this case), the slide amount control member that allows the slide is provided.
The beverage container take-out control member can have a simple structure and a small volume. Therefore, the installation space for the beverage container take-out control member in the small refrigerator can be reduced.
