On the other hand, the compressor 5e and the electric component box 5f are disposed on the upper surface 2b of the main body case 2 in a state of being stored in a box-like case 20 and unitized.
In addition, the evaporator 5 c is disposed in the rear duct 2 a formed in the main body case 2 at the rear of the display room 3. The rear duct 2a constitutes a part of the air passage which continues to the cold air discharge port of the top face of the display room 3, and the evaporator fan is provided in the air passage. The air flowing to the evaporator 5c by the operation of the evaporator fan is cooled by the evaporator 5c, becomes cold air, and is discharged to the display chamber 3 from the cold air discharge port.

[2. Detailed configuration]
The detailed configuration of the showcase 1 will be described with reference to FIGS. 3A to 4B.
FIG. 3A is a perspective view showing a configuration inside a machine room according to an embodiment of the present invention.
FIG. 3B is a side view showing the configuration inside the machine room according to the embodiment of the present invention.
FIG. 4A is a perspective view showing the configuration in the box of one embodiment of the present invention.
FIG. 4B is a side view showing the configuration in the box of one embodiment of the present invention.

As described above, in the machine room 4, as shown in FIGS. 3A and 3B, the condenser 5a, the condenser blower 5b, and the drain tray 6 are disposed.
For example, the condenser 5a is disposed at the foremost part of the machine chamber 4, and the condenser blowers 5b are juxtaposed in plurals along the horizontal direction (hereinafter referred to as "width direction") immediately behind the condenser 5a. 6 are spaced apart behind condenser blower 5b.
The operation of the condenser blower 5b forms an air flow which flows from the front to the rear, and this air flow becomes warm air by the heat release of the condenser 5a and flows to the rear drain tray 6.

  In the drain plate 6, dew condensation water or defrost water (hereinafter referred to as drain) generated in the display room 3 or the evaporator 5c passes through the drain passage 4b installed below the drain inlet (not shown) of the machine room 4. Sent in.

  The drain passage 4b includes a funnel-shaped member 4b1 located vertically below the drain inlet, and an open low-profile box-shaped member 4b2 at the top. The box-shaped member 4 b 2 is disposed on the front side below the funnel-shaped member 4 b 1 and on the rear side above the drain plate 6. Moreover, the hole 4b3 is formed in the location located above the drain pan 6 in the box-shaped member 4b2. With such a configuration, the drain that has flowed down from the drain inlet to the funnel-shaped member 4b1 flows down to the box-shaped member 4b2, and then flows down from the hole 4b3 to the drain pan 6.

  Inside the drain tray 6, a plurality of plate-like evaporation promoting members 6a are provided, which absorb drain accumulated in the drain tray 6 to promote evaporation of the drain. A plurality of evaporation promoting members 6a are arranged side by side with a gap in the width direction in an upright state in which the upper ends thereof project beyond the upper edge of the drain plate 6. By the operation of the condenser blower 5b, air flows in the gap between the condenser 5a and the evaporation promoting member 6a in this order. The air that has passed through the condenser 5a is heated by the exhaust heat of the condenser 5a, and the heated air efficiently evaporates the drain absorbed by the evaporation promoting member 6a.

As shown in FIGS. 4A and 4B, in the case 20, an electrical component box 5f is disposed on the front side thereof, and a compressor 5e is disposed adjacent to the rear left of the electrical component box 5f. Moreover, the component represented by the code | symbol 5g of the back right of the electrically equipped box 5f is an accumulator (it abbreviate | omits in FIG. 1).

In addition, a plurality of slit-shaped vents 20a are arranged vertically and in the front and back, at a location facing the cooling fan 5f1 on the left side wall of the case 20 (see FIG. 1).

[3. Action / Effect]
The operation and effect of the showcase 1 according to the embodiment of the present invention will be described.
When the compressor 5e is disposed in the machine room 4, the height of the machine room 4 and the floor surface height in the display room 3 above the machine room 4 are restricted by the height of the compressor 5e. The room 3 can not be lowered. On the other hand, according to the showcase 1 of the present embodiment, since the compressor 5e is installed on the upper surface 2b of the main body case 2, the display room 3 can be lowered in floor and expanded downward.

  Further, air flow through the machine room 4 is improved by the amount that the compressor 5e and the electrical component box 5f are not disposed in the machine room 4. Therefore, the amount of the warm air delivered to the drain pan 6 by the operation of the condenser blower 5b increases, and the drying of the drain by the warm air can be effectively performed. Further, the space in which the condenser 5a and the condenser fan 5b can be installed is expanded, and as shown in FIG. 3A, the condenser fan 5b can be installed over substantially the entire width of the condenser 5a.
