Part of the air that has passed through the cooler 16 is supplied to the suction portion 49 of the showcase 40A through the air flow path 30A. The cool air supplied to the suction part 49 of the showcase 40A flows into the duct 46 of the showcase 40A, is accelerated by the blower 48 for circulation in the display room disposed in the duct 46, and It is discharged toward the inside of the display chamber 41 from the discharge port of the case 40A. The cool air discharged into the display chamber 41 circulates in the display chamber 41, whereby the display chamber 41 of the showcase 40A is cooled to a predetermined cooling temperature. In the present embodiment, a temperature space in the freezing temperature zone is formed in the display chamber 41 of the showcase 40A. Then, the air sucked from the suction port of the showcase 40A returns into the duct 46, and a part of the returned air returns to the refrigerator unit 10 through the outflow part.

  On the other hand, a part of the remaining portion of the cold air that has passed through the cooler 16 other than that having flowed into the air flow path 30 </ b> A flows into the air flow path 30 </ b> B, and the remaining flow flows into the first radiator 13. A part of the air heated by the heat radiation action of the first heat radiator 13 through the first heat radiator 13 flows into the air flow path 30B, and the rest flows into the air flow paths 30E and 30F. To do. Here, cold air that has flowed in through the cooler 16 and air that has been heated by the heat radiation action of the first heat radiator 13 through the cooler 16 flow into the air flow path 30B. Therefore, in the air flow path 30B, the cold air and the warm air are mixed to form a predetermined temperature, here, temperature-adjusted air in a chilled temperature zone. At this time, the air passing through the first radiator 13 is air that has been once cooled by the cooler 16. Therefore, moisture contained in the air passing through the first radiator 13 is once cooled by the cooler 16 and condensed and removed. Therefore, since the air passing through the first radiator 13 has a small water content, it is possible to suppress the occurrence of condensation when heated and supplied to the showcase side.

  The temperature-adjusted air adjusted to a predetermined chilled temperature zone in the air flow path 30B is supplied to the suction part 49 of the showcase 40B. The temperature adjustment air in the chilled temperature zone supplied to the suction portion 49 of the showcase 40B flows into the duct 46 of the showcase 40B and is displayed in the duct 46, like the showcase 40A. The air is accelerated by the blower 48 for indoor circulation and discharged from the discharge port of the showcase 40B into the display chamber 41. The temperature adjustment air in the chilled temperature zone discharged into the display chamber 41 circulates in the display chamber 41, whereby the display chamber 41 of the showcase 40B has a temperature space in which the temperature is adjusted to a predetermined chilled temperature zone. Is formed. Then, the air sucked from the suction port of the showcase 40B returns into the duct 46, and a part of the returned air returns to the refrigerator unit 10 through the outflow part.

  On the other hand, the air that has flowed into the air flow paths 30E and 30F is cooled in the cooler 16 and the contained moisture is condensed and removed, and then heated in the first radiator 13 to obtain a predetermined temperature, It is temperature adjustment air adjusted to the refrigeration temperature range mentioned above. The temperature-adjusted air that has been adjusted to the refrigeration temperature zone that has flowed into the air flow paths 30E and 30F is supplied to the suction portion 49 of each showcase 40E or 40F. The temperature adjustment air in the refrigeration temperature zone supplied to the suction portion 49 of the showcase 40E or 40F flows into the duct 46 of the showcase 40E or 40F and is arranged in the duct 46, similarly to the showcase 40A. The air is accelerated by the provided circulation fan 48 for display room circulation, and discharged from the discharge port of the showcase 40E or 40F toward the display room 41. The temperature adjustment air in the refrigeration temperature zone discharged into the display chamber 41 circulates in the display chamber 41, so that the temperature in the display chamber 41 of the showcases 40E and 40F is adjusted to a predetermined refrigeration temperature zone. A temperature space is formed. Then, the air sucked from the suction port of the showcase 40E or 40F returns to the duct 46, and a part of the returned air returns to the refrigerator unit 10 through the outflow portion. Note that, similarly to the temperature adjustment air supplied to the chilled temperature zone, the temperature adjustment air supplied to the refrigeration temperature zone is subjected to the first heat dissipation after the condensed moisture once cooled in the cooler 16 is condensed and removed. Since the air is heated in the container 13, it is possible to suppress the occurrence of condensation when supplied to the showcase side.

  The air that has flowed into the air flow path 32 described above is heated by the heating action of the first radiator 13 in the process of passing through the first radiator 13. The warm air that has passed through the first radiator 13 is supplied to the suction portion 49 of the showcase 40C through the air flow path 30C. The warm air supplied to the suction portion 49 of the showcase 40C flows into the duct 46 of the showcase 40C, is accelerated by the blower 48 for circulation in the display room disposed in the duct 46, and It is discharged toward the display chamber 41 from the discharge port of the case 40C. As the cool air discharged into the display chamber 41 circulates in the display chamber 41, a temperature space adjusted to a predetermined storage temperature is formed in the display chamber 41 of the showcase 40C. Then, the air sucked from the suction port of the showcase 40C returns into the duct 46, and a part of the returned air returns to the refrigerator unit 10 through the outflow part.

  In the operation of forming the temperature space of the predetermined temperature zone in the display chamber of each showcase described above, if the heating action by the first radiator 13 becomes excessive, the electromagnetic valve 17 is closed or the refrigerant flow rate is set to Decrease and open the solenoid valve 18. By opening the electromagnetic valve 18, all or part of the high-temperature refrigerant discharged from the compressor 12 can flow into the second radiator 14 and be cooled. Thereby, the heating action in the first radiator 13 can be reduced without reducing the refrigeration capacity in the cooler 16. Therefore, it becomes possible to appropriately cool or heat the inside of each showcase to a predetermined temperature range.

  With the above configuration, the operation of the mobile sales vehicle 1 will be described. First, in a state where the mobile sales vehicle 1 stands by at a base such as a store, the above-described power outlet of the mobile sales vehicle 1 is connected to a commercial AC power source. Therefore, the compressor 12 of the refrigerator unit 10 mounted on the mobile sales vehicle 1, the blower 26 for the duct, the blower 23 for the radiator, the blower 48 for circulation in the display room of each showcase, etc. are supplied from a commercial AC power source. Driven by supply. When the refrigerator unit 10 and each showcase are operated, a predetermined temperature space is formed and maintained in the display chamber of each showcase by temperature-adjusted air (including cool air and warm air) in a corresponding temperature range. . In parallel with the operation of the refrigerator unit 10 and the showcase, the storage battery 5 is charged.

  Until the above-described charging of the storage battery 5 is completed, a product replenishment operation is performed in the display room 41 of each showcase at a base such as a store. As described above, since the temperature spaces in the corresponding temperature zones are formed and maintained in the display chambers 41 of the respective showcases, the products displayed in the display chambers 41 can be kept cool at an appropriate temperature. It becomes possible to keep warm.

  When starting to move the mobile sales vehicle 1, the power outlet is disconnected from the AC power source. When the power supply from the AC power supply is cut off, the refrigerator unit 10 and each showcase are operated by the electric power supplied from the storage battery 5. The mobile sales vehicle 1 can move from a base of a store or the like to a store opening location in each place according to a predetermined route, and the products loaded on the mobile sales vehicle 1 can be displayed and sold at each store opening location. it can.

  Here, as described above, the mobile sales vehicle 1 in the present embodiment arranges each showcase in which the display chamber 41 is configured along the side edge portions 3A, 3B and the rear edge portion 3C of the loading platform 3. doing. Accordingly, at the store opening location, the customer etc. does not enter the loading platform 3 of the mobile sales vehicle 1, and the products displayed in each showcase installed on the loading platform 3 from the outer periphery such as both sides and rear of the loading platform 3. Can be picked and picked up.

  In particular, in the mobile sales vehicle 1 according to the present embodiment, the refrigerator unit 10 for forming a predetermined temperature space in the display room 41 of these showcases is disposed in the center of the cargo bed 3 surrounded by these showcases. Has been. Therefore, the refrigerator unit 10 necessary for cooling or heating the inside of the display chamber 41 of the showcase can be arranged in the center of the loading platform 3 that tends to become a dead space by the arrangement of the showcase. The space at the center of the cargo bed 3 can be used effectively.

  Therefore, unlike the conventional mobile sales vehicle, there is no need to provide a machine room containing various devices constituting the refrigerator unit at the lower part of each showcase, and the display room 41 can be configured from the lower part of the showcase. It becomes. Accordingly, the showcases arranged at the side edge and the rear edge of the cargo bed 3 constitute the display chamber 41 from a position higher than the height of the cargo bed 3 by the thickness of the heat insulating wall of the showcase and the duct size. It becomes possible to do. With such a configuration, the mobile sales vehicle 1 according to the present invention has a showcase installed on the loading platform 3 higher than a normal store, but it is easy to use even for a relatively short customer such as an elderly person. Products can be displayed at a height.

  In particular, most of the height from the ground of a truck corresponding to a mini vehicle to the floor of the cargo bed 3 is 64 cm to 67 cm. For this reason, the lowermost display shelf on the showcase disposed on the loading platform 3 has high visibility even for elderly people and children who are relatively short, and it is easy to pick up products without bending the knees. Corresponds to the height. Therefore, the lowermost display shelf can be effectively used as a shelf having a higher advantage than other display shelves, and a higher display effect can be exhibited.

  Furthermore, in the mobile sales vehicle 1 in the present embodiment, temperature spaces of different predetermined temperature zones are formed by the refrigerator unit 10 in the display chamber 41 of each showcase 40A, 40B, 40C, 40E, and 40F. ing. Specifically, as described above, the display room 41 of each showcase installed in the mobile sales vehicle 1 includes 5 of a refrigeration temperature zone, a chilled temperature zone, a refrigeration temperature zone, a normal temperature zone, and a warmer temperature zone. A temperature-space display space is formed. Therefore, even in summer when the outside air temperature rises, the products displayed in the display room 41 can be displayed and stored at an appropriate temperature without being greatly affected by the outside air temperature. Accordingly, the mobile sales vehicle 1 is provided with a display room 41 that forms a temperature space of another kind of temperature zone, including the display room of the showcase 40D that is a temperature space of a normal temperature temperature zone. Variations of products that can be handled in the mobile sales vehicle 1 can be expanded, and the product lineup can be expanded.

  Further, the mobile sales vehicle 1 of the present embodiment includes a storage battery 5 having a predetermined capacity for driving the refrigerator unit 10, the showcase, and other devices mounted on the mobile sales vehicle 1. It is installed. The storage battery 5 has a capacity capable of continuously driving each device including the refrigerator unit 10 for, for example, 8 hours to 10 hours. Therefore, after moving to the store opening location, the mobile sales vehicle 1 can continue to operate the refrigerator unit 10 and each showcase without any trouble while the vehicle engine is stopped. It becomes possible to maintain the inside of 41 in a predetermined temperature range.

Therefore, the mobile sales vehicle 1 in the present embodiment is different from the case where the refrigerator unit 10 or the like is operated depending on the engine mounted on the vehicle, even when the outside air temperature is high and the operation efficiency is lowered. Further, it is possible to avoid the possibility that the fuel used for the movement is consumed for the operation of the refrigerator unit 10 and the return to the base such as the store becomes impossible. Further, since fuel such as gasoline is not used as a power supply source for operating a refrigeration unit mounted on the vehicle, the fuel efficiency of the vehicle itself can be improved, and the CO ₂ emission amount can be greatly increased. Can be reduced.

  After the mobile sales described above are completed, the mobile sales vehicle 1 returns to a base such as a store, and then connects the power outlet to a commercial AC power source, and the refrigerator unit 10 and the show mounted on the mobile sales vehicle 1 The case is operated again by supplying power from a commercial AC power source. Further, the storage battery 5 mounted on the mobile sales vehicle 1 is charged by connecting the power outlet to the commercial AC power source.

  The mobile sales vehicle 1 that has returned to the base of the store or the like can operate the refrigerator unit 10 and the showcase by connecting the power outlet to a commercial AC power supply. , Can be maintained in a predetermined temperature range. Therefore, when returning to the base, it is not necessary to take down the products displayed in each showcase and manage them in a cooling facility installed in a store or the like. Also, when going from the base to the mobile sales destination, since many of the products are displayed in the showcase, it is possible to leave by simply performing replenishment work. Therefore, complicated work at a base such as a store can be avoided, and workability can be improved.
