The height of the duct 50 is set such that the top plate 56 contacts the outer bottom surface of the box bottom 30 of the heat insulating box 12, and the stored items stored in the slide doors 16, 16 and the storage chamber 14. When the box bottom portion 30 is bent downward by a load such as the like, the bottom portion 30 is configured to be supported by the duct 50. That is, the height of the opening at the entrance / exit 36, that is, the distance between the mounting surface of the movable table 42 and the outer bottom surface of the box bottom 30 in the guide rails 40, 40 is an error in the assembly size of the cooling unit 26. Considering only the variation in the height of the unit itself, the cooling unit 26 is set to a value that can be taken in and out.
[0015]
[Effect of the embodiment]
Next, the operation of the refrigerated showcase according to the embodiment will be described. With the front panel removed from the chassis 24 and the entrance 36 opened, the moving base 42 of the cooling unit 26 is pushed into the machine room 28 along a pair of guide rails 40, 40 and is regulated by the stoppers 40a, 40a. The unit 26 is positioned at the stored position. At this time, the front plate 58 of the duct 50 is removed, and the suction side of the condenser 44 in the cooling unit 26 reaches a position below the top plate 56 in the duct 50. In this state, the cooling unit 26 is screwed and fixed to the guide rails 40 and 40, and the front plate 58 is screwed and fixed to the front side of the duct 50, so that the suction side of the condenser 44 is connected to the back of the duct 50. Surrounded by the plate 52, the right side plate 54, the top plate 56 and the front plate 58.
[0016]
When the condenser fan 46 is rotated after the front panel is attached to the chassis 24, the air below the base is sucked into the duct 50 through the plurality of intake holes 18 a drilled in the base 18. The air is sucked in from the suction side of the condenser 44 to exchange heat, and then blown out from the condenser fan 46 toward the compressor 48. After heat exchange with the compressor 48, the base 18 It is discharged to the outside below the base through a plurality of exhaust holes 18b drilled in the base.
[0017]
As described above, since the suction side of the condenser 44 is surrounded by the duct 50, the air after heat exchange blown out from the condenser fan 46 moves through the gap and again from the suction side of the condenser 44. It is possible to effectively prevent the sneak in phenomenon. Thereby, insufficient cooling of the heat generating parts such as the condenser 44 and the compressor 48 due to overheating in the machine room can be prevented, and efficient operation of the condenser 44 and the compressor 48 can be achieved.
[0018]
In addition, the height of the duct 50 is set so that the top plate 56 abuts against the box bottom 30, so that the box bottom 30 is lowered by the load of the slide doors 16, 16 and stored items. This can be supported by the duct 50 when bent. That is, the opening height dimension of the inlet / outlet 36 for taking the cooling unit 26 into and out of the machine room 28 can be set in consideration of only the variation in the height dimension due to an error in the assembly dimension of the unit 26. . Accordingly, it is possible to prevent the total height of the refrigerated showcase 10 itself from increasing or the volume of the storage chamber 14 from decreasing. Further, since the duct 50 also serves as a reinforcing material, it is possible to prevent an increase in the number of parts and an increase in cost by separately using the reinforcing material.
[0019]
In the embodiment, the air cooling air of the cooling unit is circulated through the air intake holes and the air exhaust holes formed in the base. However, the air intake holes and the air exhausts are provided on the side panel, the rear panel, or the front panel disposed in the chassis. It is possible to adopt a configuration in which holes are formed and air for cooling is circulated. Further, the cooling unit may be inserted into and removed from the machine room from the side or the rear, and a duct is disposed so as to surround the suction side of the condenser when the unit is stored in the machine room. Just do it. In the embodiment, the main body is composed of separate members of the heat insulating box and the chassis. However, the main body may be a single body, and the storage room and the machine room are vertically partitioned by a partition wall in the main body. Just do it.
[0020]
【The invention's effect】
As mentioned above has been described, according to the reservoir according to the present invention, a duct for the condenser in the cooling unit standing on the inner bottom surface of the machine room, may receive support partition wall separating the storage chamber and a machine chamber by said duct With this configuration, the opening height of the inlet / outlet of the cooling unit can be set considering only the variation in height due to the assembly error of the unit, and the storage can be enlarged or the storage chamber can be reduced in volume. Can be prevented. Further, since the duct is also used as a reinforcing material, it is not necessary to separately provide a member for reinforcement, and the number of parts can be reduced and the cost can be reduced. Furthermore, since the front plate facing the entrance / exit side of the machine room in the duct is configured to be detachable, the cooling unit can be taken in and out by removing the front plate.
