  On the other hand, in this merchandise storage device, an upper wind shielding plate (upper wind shielding member) 50 is disposed at a position above the main body casing 10 in the distribution center building 1. The side wind shielding plates 60 are respectively disposed at the positions where the rear body wind shielding plate 60 is located, and the rear wind shielding screen (rear wind shielding member) 70 is disposed at the position behind the main body housing 10. A front windshield 80 is disposed at a position in front of the body 10.

  The upper wind shielding plate 50 is a plate-like member having a size larger than that of the upper wall 14 of the main body casing 10, and is configured by a member having substantially zero air permeability. The upper wind shielding plate 50 is disposed at a position covering the upper wall 14 in a state where a predetermined gap is ensured between the upper wind shielding plate 50 and the upper wall 14 of the main body casing 10, and the upper draft is provided between the upper wind shielding plate 50 and the upper wall 14. A space 51 is formed.

  The side wind shielding plates 60 are plate-like members each having a size larger than that of the side wall 13 of the main body housing 10, and, like the upper wind shielding plate 50, are configured by members that have substantially zero air permeability. . The respective side wind shielding plates 60 hang downward from both side edges of the upper wind shielding plate 50 and are arranged in a state where the individual inner surfaces are in contact with the outer surface of the side wall 13 of the main body housing 10. is there. The lower ends of the side wind shielding plates 60 are in contact with or close to the floor surface 1a of the distribution center building 1, respectively.

It arrange | positions so that it may hang down from a rear edge and a front edge, respectively. The lower ends of the rear windshield 70 and the front windshield 80 are in contact with or close to the floor surface 1a of the distribution center building 1, respectively. Both side edges of the rear windshield 70 and the front windshield 80 are in contact with or close to the side windshield 60, respectively.

  The rear windshield 70 is disposed at a position covering the rear wall 12 in a state where a predetermined gap is secured between the rear windshield 70 and the rear wall 12 of the main body housing 10, and the upper ventilation space is provided between the rear windshield 70 and the rear wall 12. A rear ventilation space 71 communicated with 51 is formed. The rear ventilation space 71 has a dimension sufficient for a person to enter and exit between the rear wall 12 of the main body housing 10 and the rear windshield 70, and the space between them can be used as a passage. .

  The front windshield 80 is disposed at a position covering the front wall 15 in a state where a predetermined gap is secured between the front windshield 80 and the front wall 15 of the main body housing 10. A ventilation space 81 is configured. The front ventilation space 81 has a dimension sufficient for a person to enter and exit between the front wall 15 of the main body casing 10 and the front windshield 80, and the space between them can be used as a passage. It is.

  Although not clearly shown in the drawing, the upper windshield 50, the rear windshield 70, and the front windshield 80 are each constituted by a member having translucency, and is provided inside the distribution center building 1. It is possible to transmit the arranged illumination light (not shown).

  Further, in the product storage device, a lower ventilation duct 90 is provided between the bottom wall 11 of the main body housing 10 and the floor surface 1 a of the distribution center building 1. The lower ventilation duct 90 has an external suction port 91 at a portion corresponding to the lower edge of the product outlet 16 outside the main body housing 10, and the rear wall 12 and the rear windshield 70 outside the main body housing 10. And an external air outlet 92 at the lower part of the rear ventilation space 71 between the two. Inside the lower ventilation duct 90, a recovery fan (blower unit) 93 is disposed. When the recovery blower fan 93 is driven, it sucks air from the external suction port 91 into the lower ventilation duct 90, passes below the main body housing 10, and then sucks the air sucked into the lower ventilation duct 90 into the external blower outlet 92. It functions to blow out from.

  In the product storage device configured as described above, if the product replenishment port 12 a provided in the rear wall 12 of the main body housing 10 is opened by opening the lid member 40, each rack plate is externally attached to the main body housing 10. A product to be temporarily stored can be placed on the upper surface of 30. The products placed on the upper surface of the rack plate 30 sequentially move forward according to the inclination of the rack plate 30 by appropriately rotating rollers (not shown). Thereby, in the product storage device, the products are stored in a state in which the products are arranged in order from the front end side to the rear end side of the rack plate 30, and the products always stored in the front row of the rack plate 30. Can be taken out from the product outlet 16.

  Meanwhile, in the product storage device, when the refrigeration cycle including the evaporator 24 is driven and the circulation blower fan 23 is driven, the air inside the main body housing 10 is sucked into the internal circulation duct 20 from the internal suction port 21. The air sucked into the internal circulation duct 20 is blown out from the internal air outlet 22 into the main body housing 10. Since the air sucked into the internal circulation duct 20 is cooled by heat exchange when passing through the evaporator 24, the air is always supplied to the inside of the main body housing 10 in a cooled state. As a result, even if a certain period of time is required until the products stored in the main body housing 10 are sorted through the rack plate 30, temporary storage is performed while maintaining a desired temperature, for example, the freezing temperature. It becomes possible to do.

  Here, in this kind of product storage device, since the product outlet 16 provided on the front wall 15 of the main body housing 10 is always open, the temperature-controlled internal air leaks to the outside and energy loss occurs. There is a risk of inviting. Further, when the lid member 40 is opened to replenish the product while the refrigeration cycle including the evaporator 24 is being driven and the product replenishment port 12a is opened, the inside of the main body housing 10 is opened through the product replenishment port 12a. There is a risk that the outside air may enter and cause energy loss.

  However, according to the above-described product storage device, when the recovery blower fan 93 is driven, the lower ventilation duct 90 extends from the external suction port 91 opened to the portion corresponding to the lower edge of the product take-out port 16 outside the main body housing 10. The air is sucked into the lower air duct 90 and the air sucked into the lower air duct 90 is blown out to the rear airflow space 71 through the external air outlet 92. The air blown into the rear ventilation space 71 is guided and rises between the rear wall 12 of the main body casing 10 and the rear wind shielding screen 70, and the upper ventilation between the upper wall 14 and the upper wind shielding plate 50. After moving forward in the space 51, it is guided and lowered by the front windshield 80 and reaches the external suction port 91 or the internal suction port 21 of the internal circulation duct 20. The air sucked into the lower ventilation duct 90 from the external suction port 91 is cooled inside the main body housing 10. Therefore, the periphery of the main body housing 10 is surrounded by the cooled air, and heat exchange with the outside air through the main body housing 10 is suppressed, and energy saving can be achieved.

  In addition, the rear ventilation space 71 formed between the main body housing 10 and the rear wall 12 has a dimension sufficient for people to enter and exit. Further, as the rear windshield 70, a flexible one is applied. For this reason, it is possible to enter the rear ventilation space 71 and replenish the product into the main body housing 10 from the product replenishment port 12a. In this case, since the temperature-adjusted air leaked from the product outlet 16 is supplied to the rear ventilation space 71, the main body can be used even when the lid member 40 is opened and the product replenishment port 12a is opened. There is no risk of sudden temperature changes inside the housing 10. As a result, the energy consumption can be reduced even in the product storage device having the product replenishment port 12a on the rear wall 12 of the main body casing 10. As the rear windshield 70 and the front windshield 80, curtain-shaped ones may be applied, but if they are formed in a warm shape by providing elongated slits extending in the vertical direction, people can enter and exit. This can be facilitated.

FIG. 3 shows a product storage device according to Embodiment 2 of the present invention. As in the first embodiment, the product storage device illustrated here is installed inside the distribution center building 1 serving as a distribution base, and sorts products that are carried in a desired temperature state, for example, a frozen state, for each shipping destination. The present invention is applied as a temporary storage rack in the work, and the first embodiment is different from the first embodiment in the number of rack plates 30 provided inside the main body housing 10 and the rack plates 30 for arranging products outside the main body housing 10. The difference is that it is arranged. That is, in the commodity storage device of the second embodiment, the two-stage rack plate 30 is disposed inside the main body housing 10. A new rack plate 130 is disposed between the upper wall 14 of the main body housing 10 and the upper wind shielding plate 50, and the function of the rack plate is imparted to the upper wall 14 of the main body housing 10. The rack plate disposed outside the main body housing 10 (hereinafter referred to as “external rack plate 130” when distinguished from the rack plate 30 disposed inside the main body housing 10) is the main body housing 10. As in the case of the rack plate 30 (hereinafter referred to as “internal rack plate 30” when distinguished from the external rack plate 130), the respective rack plates 30 are inclined to be slightly lower toward the front. A product mounting surface is formed on each upper surface. Although not clearly shown in the figure, the point that a plurality of rollers (not shown) are rotatably disposed along the front-rear direction on the upper surface of each external rack plate 130 is the same as in the first embodiment. is there. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

The products placed on the rack plates 30 and 130 are sequentially moved forward according to the inclination of the rack plates 30 and 130 by appropriately rotating rollers (not shown). Thereby, in the product storage device, the products are stored in a state in which the products are sequentially arranged from the front end side to the rear end side of the rack plates 30 and 130, and are always placed in the front row of the rack plates 30 and 130. The stored product can be taken out from the front wall 15 side of the main body housing 10.

  Meanwhile, in the product storage device, when the refrigeration cycle including the evaporator 24 is driven and the circulation blower fan 23 is driven, the air inside the main body housing 10 is sucked into the internal circulation duct 20 from the internal suction port 21. The air sucked into the internal circulation duct 20 is blown out from the internal air outlet 22 into the main body housing 10. Since the air sucked into the internal circulation duct 20 is cooled by heat exchange when passing through the evaporator 24, the air is always supplied to the inside of the main body housing 10 in a cooled state. As a result, even if a certain period of time is required until the products stored in the main body housing 10 are sorted through the internal rack plate 30, the desired temperature, for example, the freezing temperature is temporarily maintained. It can be stored.

  On the other hand, according to the product storage device described above, when the recovery blower fan 93 is driven, the lower ventilation duct 90 extends from the external suction port 91 opened to a portion corresponding to the lower edge of the product outlet 16 outside the main body housing 10. The air is sucked into the lower air duct 90 and the air sucked into the lower air duct 90 is blown out to the rear airflow space 71 through the external air outlet 92. The air blown into the rear ventilation space 71 is guided and rises between the rear wall 12 of the main body casing 10 and the rear wind shielding screen 70, and the upper ventilation between the upper wall 14 and the upper wind shielding plate 50. After moving forward in the space 51, it is guided and lowered by the front windshield 80 and reaches the external suction port 91 or the internal suction port 21 of the internal circulation duct 20. The air sucked into the lower ventilation duct 90 from the external suction port 91 is cooled inside the main body housing 10. Therefore, the cooled air can be supplied to the goods temporarily stored in the external rack plate 130, and even if it takes some time until the goods are sorted, the desired temperature, for example, the refrigeration temperature It is possible to store temporarily while maintaining the above. Furthermore, the periphery of the main body housing 10 is surrounded by the cooled air, so that heat exchange with the outside air through the main body housing 10 is suppressed, and energy saving can be achieved.

  In addition, the rear ventilation space 71 formed between the main body housing 10 and the rear wall 12 has a dimension sufficient for people to enter and exit. Further, as the rear windshield 70, a flexible one is applied. For this reason, it is possible to enter the rear ventilation space 71 and replenish the product into the main body housing 10 from the product replenishment port 12a. In this case, since the temperature-adjusted air leaked from the product outlet 16 is supplied to the rear ventilation space 71, the main body can be used even when the lid member 40 is opened and the product replenishment port 12a is opened. There is no risk of sudden temperature changes inside the housing 10. As a result, the energy consumption can be reduced even in the product storage device having the product replenishment port 12a on the rear wall 12 of the main body casing 10.

  In addition, in Embodiment 1 and Embodiment 2 mentioned above, the temporary storage rack used in the case of a picking operation | work is illustrated, However, The goods storage apparatus which concerns on this invention is not restricted to this, For example, in a shop The present invention can also be applied as a showcase for displaying products for sale.
