  FIG. 8 shows a connection state between the lower duct member 7a and the wind tunnel 60 of the cooling / heating unit 6. FIG. 8A shows a state where the wind tunnel 60 is connected to the lower duct member 7a, and FIG. The state which decomposed | disassembled the duct member 7a and the wind tunnel 60 is shown. In FIG. 8, the upper duct member 7b is omitted.

  As shown in FIG. 8, the wind tunnel 60 has a size that surrounds the inlet-side opening 74 of the lower duct member 7 a, and locking pieces 611 and 612 that protrude rearward are formed on the rear edges of the left and right side walls 61. I have. The locking piece 611 is formed as a trapezoidal protrusion inserted into a slit-shaped locking groove 77 formed on the front wall 71 of the lower duct member 7a, and a bulging portion 611a is provided on the plate surface. . The locking piece 612 is formed as a hook-shaped protrusion that is inserted into a slit-shaped locking groove 78 formed in the front wall 71 of the lower duct member 7a.

  The vending machine having such a configuration opens the outer door 2 and the heat insulating inner door 3 shown in FIG. 1 so that the product S is placed in the product storage passage 43 (product column) defined in the product storage shelf 10 from the product input port 44. Loaded. The product loaded first in the product storage passage 43 (product column) is held by the pedal member BM1 of the product delivery device BM protruding in the product storage passage 43 and becomes the product with the highest sales order (also called sales product). The next loaded product is stacked on the front side of the sales product held by the pedal member BM1 to become the next sales product, and the subsequently loaded product is sequentially stacked in front of the next sales product. After the product is loaded, the product S stored in the product storage rack 4 is cooled or heated by the cooling / heating unit 6 and is stored in a cold or hot state suitable for sale and is ready for sale (sales standby state).

  Here, referring to FIGS. 9 and 10, the flow of the internal air (cold air or warm air) circulating in the product storage when the product stored in the product storage rack 4 is cooled or heated by the cooling / heating unit 6. I will explain. FIG. 9 shows the state of the circulating airflow when the zone is cooled or heated, and FIG. 10 shows the state of the circulating airflow when the whole is cooled or heated.

  Although not shown in the figure, it has a control unit that controls the entire vending machine. This main control unit includes a ROM that stores various execution programs, a RAM that stores various data, and various input signals. The internal lower fan F1 and the internal upper fan F2 are driven and controlled according to a program for zone cooling or zone heating, overall cooling, or overall heating.

  FIG. 9 shows the state of the circulating airflow at the time of zone cooling or zone heating. In this case, the internal lower fan F1 and the internal upper fan F2 of the cooling / heating unit 6 are driven. In this case, the internal lower fan F1 is controlled to drive at a predetermined low speed lower than the rated speed (for example, 40% to 60% of the rated speed), while the internal upper fan F2 is rated. Drive control is performed in the following manner. When the internal lower fan F1 is driven at a predetermined low rotational speed lower than the rated rotational speed, the internal air (cold air cooled by the cooler 6a or warm air heated by the heater 6b) is cooled by the cooling / heating unit 6. After entering the inside of the lower duct member 7a from the wind tunnel 60 through the inlet side opening 74 of the lower duct member 7a, the air is blown out from the outlet side opening 78 of the lower duct member 7a to the lower end of the upper duct member 7b. The flow rate of the internal air blown out from the outlet side opening 78 of the duct member 7a to the lower end of the upper duct member 7b and ascending the upper duct member 7b is a predetermined low speed that the internal lower fan F1 is lower than the rated speed. Since it is driven, it is relatively weak (that is, it is weaker than the flow velocity when the lower fan F1 is driven at the rated rotational speed), and the circulating airflow A1 and the circulating airflow A1 from the vent hole 70 formed in the upper duct member 7b. Thus, the airflow A0 reaches the upper part of the upper duct member 7b (the upper end of the product storage) while being divided. The circulating airflow A0 that has reached the upper end of the upper duct member 7b becomes the circulating airflow B in a manner of turning downward when the internal upper fan F2 is driven. The circulating airflow B is directed downward while being divided into the circulating airflow B1 by the attitude control plate 7. The circulating airflows A1 and B1 are divided into the circulating airflows A2 and B2 through the vent holes 10a drilled in the product storage shelf 10 by the suction of the lower fan F1 in the warehouse, and become the circulating airflow C. It circulates through 5a so as to return to the internal lower fan F1. The circulating airflows A1 and A2 are located in a zone near the rear end of the product storage passage 43 (product column) in the product storage shelf 10 below the fifth level from among the product storage shelves 10 arranged in multiple stages in the vertical direction. The stored products are washed and cooled or heated, while the circulating airflows B1 and B2 are the product storage shelves on the upper side (the sixth and subsequent steps from the bottom) of the product storage shelves 10 arranged in multiple stages in the vertical direction. 10, the product stored in the zone near the rear end of the product storage passage 43 (product column) is washed and cooled or heated.

  Here, when the product S is placed on the product storage shelf 10, the product S closes the ventilation hole 10 a at the projected portion of the product S viewed from the upstream side in the flow direction of the circulating airflows C, A 2, and B 2. The product and the partition plate 42 (or the rack side plate 41) generated when the gap outside the projected portion of the product S, that is, the width of the product storage passage 43 (product column) is set slightly longer than the length of the product S. The vent hole 10a corresponding to the gap between the two is opened. Accordingly, even when the product S is placed on the product storage shelf 10, the circulating airflows C, A2, and B2 are formed (if the product S is compared to a shoji of a Japanese-style building, the circulating airflow D is a gap. Equivalent to wind). Thus, when zone cooling or zone heating is performed, the internal lower fan F1 is driven and controlled in a mode (for example, 40% to 60% of the rated rotational speed) that is a predetermined low speed rotational speed lower than the rated rotational speed. By controlling the driving of the internal upper fan F2 at a rated rotational speed, the product S (stored in the product storage rack 4) stored in the zone near the rear end of the product storage passage 43 of the product storage shelf 10 of each stage. It is possible to cool or heat the products S) having a high sales order to a temperature suitable for sales without any temperature difference.

  The interior lower fan F1 is controlled to drive at a predetermined low speed (for example, 40% to 60% of the rated speed) lower than the rated speed (the upper fan F2 is controlled to drive at the rated speed). ), The product stored in the zone near the rear end of the product storage passage 43 of the product storage shelf 10 in each stage when the internal lower fan F1 is driven and controlled at 40% or less of the rated rotational speed. When it takes a long time to cool or heat S to an appropriate sales temperature, a temperature difference occurs in each stage of the product S in the zone, and the internal lower fan F1 is driven and controlled at 60% or more of the rated speed Although there is no great difference in the time until the product S stored in the zone near the rear end of the product storage passage 43 of each stage of the product storage shelf 10 is cooled or heated to a suitable sales temperature, the product storage shelf 10 of each stage Product storage passage 4 Temperature difference product S contained in the rear end zone that occurs has been confirmed by our experiments for. Rotating the lower fan F1 in the cabinet at the rated speed where there is no great difference in the time until the product S stored in the zone near the rear end of the product storage passage 43 of the product storage shelf 10 at each stage is cooled or heated to a suitable sales temperature. Although the cause of the temperature difference in the product S at each stage in the zone when the drive control is performed at 60% or more of the number has not been sufficiently analyzed, the lower fan F1 is driven at 60% or more of the rated speed In the case of control, the flow rate of the internal air rising in the upper duct member 7b becomes faster and has straightness, so that the circulating airflow A1 from the vent hole 70 formed in the upper duct member 7b is reduced. This is thought to be due to

  FIG. 10 shows the state of the circulating airflow when the entire cooling or the entire heating is performed. In this case, the internal lower fan F1 of the cooling / heating unit 6 is driven while the internal upper fan F2 is stopped. In this case, the internal lower fan F1 is driven and controlled so as to rotate at a high speed at the rated rotational speed. When the internal lower fan F1 is driven and controlled at a high speed, the flow rate of the internal air (circulating airflow A0) rising up the upper duct member 7b via the lower duct member 7a becomes a fast and fast moving straight air. The diversion (diversion corresponding to the circulating air flow A1 as shown in FIG. 9) discharged from the inside of the member 7b to the inside of the product storage through the vent hole 70 of the upper duct member 7 is reduced. For this reason, most of the interior air blown from the outlet side opening 78 of the lower duct member 7a to the lower end of the upper duct member 7b reaches the upper end of the upper duct member 7b.

  The circulating airflow A0 that reaches the upper end of the upper duct member 7b is provided at the rear end of the shielding member 200 that is located above the internal upper fan F2 and that is spaced from the internal upper fan F2. The guide plate 202 is sprayed. Thus, since it is comprised so that the circulating airflow A0 which rose through the said upper duct member 7b by the shielding member 200 may prevent contacting with the upper wall 1a of the main body cabinet 1, especially goods are cooled. In this case, the circulating airflow A0 (cold air) rising through the upper duct member 7b is in direct contact with the upper wall 1a of the main body cabinet 1 to prevent condensation on the upper wall 1a due to the temperature difference between the inside and the outside of the box. can do.

  Here, since the guide plate 202 of the shielding member 200 is provided so as to be inclined downward, the circulating airflow A0 that has risen through the upper duct member 7b is forwarded by the shielding plate 200 via the guide plate 202. It becomes the circulation airflow D guided to. The circulating airflow E reaches the front of the product storage, and the product stored near the front end of the product storage passage 43 (product column) of the product storage shelf 10 is washed and cooled or heated. After descending, the product returns to the internal lower fan F1 through the vent hole 5a of the product carry-out shooter 5. In this way, the air in the product storage box is sucked into the lower cabinet fan F1 through the vent hole 5a of the product carry-out shooter 5 by the driving of the lower cabinet fan F1, so that the suction of the lower cabinet fan F1 is performed. The circulating airflow D guided forward by the shielding plate 200 is also diverted gradually through the ventilation holes 10a perforated in the product storage shelf 10 to the downward circulating airflow D1 and descends in the product storage. In the process, all the products stored in the product storage passage 43 (product column) of the product storage shelf 10 are washed and cooled or heated. As described above, in the case of overall cooling or overall heating, the internal lower fan F1 is controlled to drive at a rated rotational speed while the internal upper fan F2 is stopped to drive the upper duct member 7b. After the internal air reaches the upper end of the upper duct member 7b without being diverted to the inside of the product storage through the vent hole 70, the product storage rack becomes the circulating airflows D and D1 guided forward by the shielding member 200. 4 can cool or heat the products in all the regions stored in 4 to a temperature suitable for sale.

  As described above, according to the vending machine according to this embodiment, a plurality of products are arranged in a line in the front-and-rear direction in a posture of lying down in the product storage of the main body cabinet 1 constructed as a heat-insulating housing. The product storage racks 10 defining the product storage passages 43 to be stored are provided in a plurality of stages in the vertical direction, the product storage racks 4 are inclined forward and downward, and the products S stored in the product storage passages 43. A cooling / heating means (cooling / heating unit 6) having an in-compartment lower fan F1 that cools or heats the product to a temperature suitable for sale is arranged in the top-bottom order, and the product storage shelf 10 becomes a product input port 44. Inclined so that the rear side serving as the product outlet 45 becomes lower than the front side, and the products S stored in a posture lying down in the product storage passage 43 in the vicinity of the product outlet 45 are cut out and delivered one by one. A product drop passage 46 extending in the vertical direction is formed between the rear end of the product storage shelf 10 and the back wall 1c of the main body cabinet 1, and is carried out from the product carry-out device BM. In the vending machine in which the finished product S is delivered onto the product carry-out shooter 5 through the product drop passage 46, the product S extends in the vertical direction along the back wall 1 c of the main body cabinet 1. It is arranged in a mode, and is guided in a mode of raising the cool air or the heated warm air cooled by the cooling / heating means (cooling / heating unit 6) blown by the internal lower fan F1, and the center of the plate surface A duct member (upper duct member 7b) having a vent hole 70 is provided from the region to the lower region, and the duct member (upper duct) is positioned above the rear end of the uppermost product storage shelf 10. An internal upper fan F2 that blows the cool air or warm air that has risen through the material 7b) downward through the product drop passage 46 is provided, and the lower internal fan F1 is rated for overall cooling or overall heating. While driving at a rotational speed, the internal upper fan F2 is stopped, and when cooling or heating the zone, the lower fan F1 is driven at a predetermined low speed lower than the rated rotational speed. On the other hand, by driving the internal upper fan F2 in a mode that achieves the rated rotational speed, the duct member (upper part) is driven by the internal lower fan F1 that is driven in a mode that achieves the rated rotational speed when the entire cooling or overall heating is performed. The inside air that has been moved straight up in the duct member 7b) is blown forward in the product storage by the stop of the upper fan F2 and stored in the product storage rack 4. The product lower fan F1 is automatically cooled or heated to an appropriate sales temperature without a temperature difference, and is driven at a predetermined low speed lower than the rated speed when zone cooling or zone heating is performed. As a result, the straightness of the internal air that rises in the duct member (upper duct member 7b) is lost, and a part of the internal air that rises in the duct member (upper duct member 7b) thereby becomes part of the duct member (upper duct). Near the rear end of the product storage passage 43 of the product storage shelves 10 below the middle of the product storage shelves 10 that are flown into the interior from the vent hole 70 formed in the member 7b) and arranged in a plurality of stages in the vertical direction. While the product S stored in the zone is concentrated and cooled or heated, the internal air rising to the upper end of the duct member (upper duct member 7b) is directed downward of the product drop passage 46 by the internal upper fan F2. The products S stored in a zone near the rear end of the product storage passage 43 of the product storage shelf 10 on the upper stage side among the product storage shelves 10 arranged in a plurality of stages in the vertical direction are concentrated by being blown. Cooling or heating the product S stored in a zone near the rear end of the product storage passage 43 of the product storage shelf 10 from the upper side to the lower side automatically concentrates and cools or heats the product S at a suitable sales temperature without any temperature difference. There is an effect that it is possible to provide a vending machine capable of performing the above.
