As shown in FIG. 4, the compressor 10 is installed on one end side (right side when viewed from the front) of the bottom surface of the machine room 3 in a posture facing the depth direction. This compressor 10 is the same as the existing one.

A condenser 11 is provided beside the compressor 10. The condenser 11 is formed to be shorter than the compressor 10. For this purpose, the condenser 11 has a generally long shape in the width direction, and has a structure in which three condenser fans 14 are mounted side by side on the rear side. It is shaped to be short while keeping the capacity.

At the other end of the bottom of the machine room 3, a cooler 12
And a cooling fan 15. The cooler 12 and the cooling fan 15 are housed in a shallow dish-shaped heat insulating case 16. The cooler 12 is formed in a shorter shape than the conventional one. For this purpose, by disposing a drain pipe (not shown) further to the side of the heat insulating case 16 (the far side in FIG. 4), a space in the depth direction near the installation position of the cooler 12 is gained, and the cooling is performed accordingly. The dimension in the depth direction of the cooler 12 was made longer, and the dimension in the width direction was made longer by utilizing the space accompanying the relocation to the end side of the compressor 10, thereby ensuring the same capacity as the conventional cooler. The shape is short. On the other hand, the cooling fan 15
2 is accommodated in an oblique posture on the side. As a result, the height of the cooling fan 15 is reduced while ensuring the flow rate of air. As described above, as shown in FIG.
The positions of the upper surfaces of the cooler 12 and the cooling fan 15 housed in the compressor 6 are suppressed to approximately the same level as the upper surface position of the compressor 10.

As shown in FIG. 3, a short heat insulating plate 18 is provided between the end of the heat insulating case 16 on the cooling fan 15 side and the lower end of the vertical heat insulating plate 6A on the right side in FIG. A long transverse heat insulating plate 19 is disposed so as to cover the upper surface of the condenser 11 from the opposite end of the heat insulating case 16, and an end of the heat insulating plate 19, Between the lower end of the vertically oriented heat insulating plate 6B on the left side, a heat insulating plate 20 in an oblique posture is stretched so as to cover the upper right portion of the compressor 10 in FIG.

The display room 2 is provided with a bottom plate 21. As shown in FIG. 3, the bottom plate 21 is stretched horizontally immediately above the cooler 12, and has a stepped surface provided with a high surface 22 having a predetermined dimension higher at the end portion where the compressor 10 is installed. It is formed in a shape. Then, the lower surface of the bottom plate 21, the heat insulating plate 18, the heat insulating case 16, and the heat insulating plate 1
A lower passage 24 passing through the cooler 12 and the cooling fan 15 is formed between the lower passages 9 and 20. In addition, the above-mentioned bottom plate 2
1 from the left and right end portions, respectively, a vertically oriented heat insulating plate 6A,
6B, the side plate 23 is formed so as to stand up with a predetermined gap therebetween, and is connected to the inner surface of the front panel 7.
Side passages 25A and 25B communicating with the air passage are formed.

As shown in FIG. 5, a passage forming panel 26 made of a transparent resin plate having a double structure is disposed inside the upper surface of the front panel 7, and an upper passage 27 is interposed therebetween.
Are formed, and both ends of the upper passage 27 are connected to the side plates 23.
Through the opening 28 formed in the left and right side passages 25
A, 25B. In addition, passage configuration panel 2
The lower surface of 6 is formed in a slanted shape having a downward slope toward the back, a dew-drop prevention film 30 is stretched on the surface thereof, and a dew receiver 31 is provided at the lower end.

When the refrigeration cycle 4 and the cooling fan 15 are driven, as shown by arrows in FIG. 3, the air sucked by the cooling fan 15 passes through the cooler 12 to generate cool air. The cool air passes through passages 24 and 25B,
Flowing around the display room 2 while passing through 27 and 25A,
Circulation circulation such as suction to the cooler 12 again occurs, whereby the inside of the display room 2 is indirectly cooled.

On the back side of the display room 2, as shown in FIG. 2, a back plate 33 is provided only behind the above-mentioned portion of the bottom plate 21 where the high-order surface 22 is provided. The opening 8 described above is formed toward the side. The opening 8 is divided right and left by a partition frame 35 to form two entrances 36, and each entrance 36
Is provided with a sliding door 38 in which two glass doors 37 are arranged in a sliding manner. In the case of a product having a narrow frontage, a sliding door may be constituted by only two glass doors without providing a partition frame.

The display case 1 of this embodiment has the above-described structure, and the compressor 10 is arranged at one end of the machine room 3 in the depth direction, and is restricted by the height of the compressor 10. The raised portion of the bottom surface of the display room 2 is provided as the high surface 22 only in a narrow region above the compressor 10, and in most other regions, the condenser 11 and the cooler 1 are provided.
2 are flattened and the cooling fan 15 is arranged in an oblique attitude, and the bottom surface is lowered accordingly. Therefore, when the total height of the display case 1 is set to be the same as that of the conventional product, the capacity of the display room 2 and the height of the entrance 36 can be increased, and a large amount of food such as sushi nata is used. Not only can it be stored, it also makes it easier to put food in and out, making it easier to use.

On the other hand, when the capacity of the display room 2 and the size of the entrance 36 are set to be the same as those of the conventional product, the display case 1
Can be reduced. Then, for example, it becomes easier to provide sushi to the customer of the counter through the display case 1, and the usability is improved in another sense. In addition, since the high-order surface 22 on the bottom surface of the display room 2 is also a portion that is easily noticeable to customers, it can be effectively used as a place for placing products to be advertised to customers.

<Second Embodiment> FIG. 6 shows a second embodiment of the present invention.
