Further, the door body support member 40 holds the shaft portion 32 on the right side of the right edge portion of the rear surface opening 15 while separating the shaft portion 32 rearward from the rear surface 14 of the case body 10.

  As shown in FIG. 3, when the door body 30 is opened, such a door body support member 40 slides backward on the shelf board 17 as indicated by a two-dot chain line in FIG. 3. The door body 30 is allowed to move from the possible region S so that not only the gasket member 31 but also a member attached to the front surface of the door body 30 is retracted.

  The cooling unit 50 is disposed in the machine room 12 of the case body 10. The cooling unit 50 includes a cooler 51, a radiator 52, a circulation fan (circulation means) 53, and a radiation fan (blower means) 54.

  The cooler 51 is disposed below the suction port 61 formed on the bottom surface of the storage chamber 11 that divides the storage chamber 11 and the machine chamber 12, and is thermally connected to a cold temperature portion of the Peltier element 55. It is. Here, the Peltier element 55 is a conventionally known element, in which p-type semiconductors and n-type semiconductors are alternately connected in series by electrode plates, and insulating plates are disposed on the front and back of these semiconductors. In such a Peltier element 55, when a direct current is applied to the electrode plate, one insulating plate absorbs heat (becomes a cold part) and the other insulating plate generates heat (becomes a high temperature part).

  The cooler 51 is made of a material having excellent thermal conductivity, and although not shown in the drawing, a plurality of fins are provided, and an air passage for allowing air to pass between the fins is formed. ing. The cooler 51 cools the air passing through the air passage by the cold heat given from the Peltier element 55.

  The radiator 52 is disposed on the front side of the cooler 51 and is thermally connected to a high temperature portion of the Peltier element 55. The radiator 52 is made of a material having excellent thermal conductivity, and although not clearly shown in the drawing, a plurality of fins are provided, and an air passage for allowing air to pass between the fins is formed. ing. The heat radiator 52 heats the air passing through the air passage by the high-temperature exhaust heat given from the Peltier element 55 to radiate heat.

  The circulation fan 53 is located on the rear side of the cooler 51 inside the wind tunnel 56 formed so as to communicate with the suction port 61 and the discharge port 62 formed on the bottom side of the storage chamber 11 on the rear side of the suction port 61. It is arranged. The circulation fan 53 is driven to suck the air inside the storage chamber 11 through the suction port 61 and allows the sucked air to pass through the air passage of the cooler 51.

  The circulation fan 53 discharges the air that has passed through the air passage of the cooler 51 to the storage chamber 11 through the discharge port 62, so that the air inside the storage chamber 11 is between the storage chamber 11 and the machine chamber 12. It is something to circulate in.

  The heat dissipation fan 54 is disposed on the front side of the heat radiator 52. The heat radiating fan 54 is driven to suck outside air through the suction port 63 formed on the bottom surface of the machine room 12 and to pass through the air passage of the radiator 52. The heat radiating fan 54 blows outside air that has passed through the air passage of the radiator 52 to the outside through the air outlet 64 formed in the bottom surface of the machine room 12.

  In addition to the suction port 61 and the blower port 64, a drain water discharge port 65 is formed on the bottom surface of the machine room 12, that is, the bottom surface of the case body 10, and a drain pan 71 and a guide member 75 are provided. It is.

  The drain water discharge port 65 is formed on the rear side of the air outlet 64 and is used to discharge the drain water generated inside the case body 10 (for example, the cooler 51 and the like) and moving through the gutter member 66 to the outside. Is the opening.

  The drain pan 71 is disposed below the drain water discharge port 65 and stores drain water discharged through the drain water discharge port 65. As shown in FIG. 4, the drain pan 71 is supported by a pair of left and right drain support members 73 formed in a manner in which a flange portion 72 formed at the upper portion projects downward from the bottom surface of the machine chamber 12.

  The guide member 75 is formed by bending a flat plate-like member, and is arranged in such a manner as to protrude downward from the bottom surface of the machine chamber 12 between the suction port 63 and the blower port 64. The guide member 75 has a base portion 751, a downward extension portion 752, and a rear extension portion 753.

  The base 751 is a part that is attached to the bottom surface of the machine room 12. The downward extending portion 752 is a portion that extends downward from the rear end edge portion of the base portion 751. The rear extension 753 is a part extending rearward from the lower end that is the extension end of the lower extension 752.

  The guide member 75 is formed such that the length in the left-right direction is larger than that of the suction port 63 and the air outlet 64, and that air blown from the air outlet 64 passes toward the front air inlet 63. It guides to pass around the drain pan 71 on the rear side while regulating. 1 is a leg portion of the case main body 10, and 34 is a handle portion provided on the rear surface 14 of the door body 30.

  In the showcase having the above-described configuration, the circulation fan 53 is driven in a state where the door 30 closes the rear opening 15, so that the internal air of the storage chamber 11 passes through the suction port 61 and the air passage of the cooler 51. And then discharged to the storage chamber 11 through the discharge port 62, thereby cooling the air inside the storage chamber 11, thereby cooling the product placed on the product placement shelf 16. .

  On the other hand, when the heat radiating fan 54 is driven, outside air passes through the air passage of the radiator 52 through the suction port 63 and is heated, and then blown out through the air outlet 64. The air blown out moves to the rear by the guide member 75, passes around the drain pan 71, and is discharged.

  Further, when the showcase performs an operation of taking out the product placed on the product placement shelf 16, the rear opening 15 is opened by opening and moving the door body 30. Thereafter, the shelf 17 of the product placement shelf 16 on which the desired product is placed is pulled out rearward, so that the shelf 17 slides rearward to take out the product. Work is done.

  After the product is taken out, an extrusion operation is performed in which the shelf board 17 that has been pulled out is pushed forward, whereby the shelf board 17 slides forward. Thereafter, the door body 30 is closed and moved, whereby the gasket member 31 is attracted to the peripheral edge of the rear surface opening 15 on the rear surface 14 of the case body 10 and the rear surface opening 15 is closed.

  According to the showcase according to the present embodiment as described above, the rear body opening 15 is opened by opening and moving the door body 30, and the shelf plate 17 of the desired product placement shelf 16 is pulled out. By operating and slidingly moving the shelf 17 through the rear opening 15 to the outside of the case body 10, the case body 10 can be moved without having to put the fingers of the store employees into the case body. It is possible to perform operations such as taking out products from the shelf plate 17 slid to the outside. Therefore, operations such as taking out a product can be easily performed.

  In particular, when the door body 30 is opened, the door body support member 40 is attached not only to the gasket member 31 but also to the front surface of the door body 30 from the region S that can be slid rearward of the shelf board 17. Since the door body 30 is allowed to open so that the member is retracted, the gasket member 31 and the shelf board 17 do not interfere with each other, and the gasket member 31 can be prevented from being damaged. Since the gasket member 31 can be prevented from being damaged in this way, the sealing performance of the storage chamber 11 can be maintained for a long period of time when the door 30 eventually closes the rear opening 15. At the same time, the service life can be extended.

  Further, since the door body support member 40 holds the shaft portion 32 at a position separated rearward from the rear surface 14 of the case main body 10, the front surface of the gasket member 31 can be moved when the door body 30 closes the rear surface opening 15. The case main body 10 can be brought into contact with the peripheral edge portion of the rear surface opening 15 on the rear surface 14. That is, when the door body 30 closes the rear opening 15, only the gasket member 31 disposed on the right side of the front surface of the door body 30 closest to the shaft portion 32 is elastically deformed before the other gasket members 31. It is possible to prevent the gasket member 31 from being damaged before the other gasket members 31. Therefore, the service life can be extended by this as well.

  Further, since the gasket member 31 is a magnet gasket, when the door body 30 that moves and closes to the case body 10 to some extent, the gasket member 31 is attracted to the peripheral portion of the rear opening 15 of the case body 10 by the action of magnetic force. The airtightness of the storage chamber 11 can be improved, and the door body 30 can reliably close the rear surface opening 15.

  According to the showcase, the cooler 51 and the circulation fan 53 can cool the internal air of the storage chamber 11 to cool the product placed on the product placing shelf 16 well. Since the guide member 75 passes the heated outside air toward the drain pan 71, the drain water generated inside the case main body 10 can be evaporated and processed.

  In particular, by allowing the outside air heated by the radiator 52 to pass toward the drain pan 71, the drain pan 71 can be downsized. By reducing the size of the drain pan 71 in this way, the wind tunnel 56 through which the air cooled by the cooler 51 passes can be relatively enlarged. Therefore, the cooling efficiency of the product by the cooler 51 can be improved.

  Further, by passing the outside air heated by the guide member 75 toward the drain pan 71, an evaporating sheet or the like for evaporating the drain water stored in the drain pan 71 is not required, and the manufacturing cost is increased. It can also be suppressed.

  Furthermore, by allowing the outside air heated by the guide member 75 to pass toward the drain pan 71, the outside air passes toward the rear. The outside air used for drain water evaporation is not blown out to those who wish.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the embodiment described above, the door body support member 40 is disposed on the right edge of the rear opening 15 on the rear surface 14 of the case body 10. However, in the present invention, the door body support member 40 is formed on one side edge of the rear opening. If there is, the arrangement location is not particularly limited.
