The unit portion 3 includes an angle member (not shown) extending from the rear portion (the other end portion) to the lower portion, and the upper end of the rear side of the angle member passes through the connecting portion 4A to the rear portion (the other end portion) of the display portion 2. As a result, the display unit 2 and the unit unit 3 are integrated with sufficient strength. The unit base 18 of the unit unit 3 is fixed by welding to the lower side of the angle described above, and a machine room 20 is formed in a space above the unit base 18, and a part of the refrigerant circuit of the cooling unit 12 is formed in the machine room 20. The heavy components such as the compressor 19, the condenser 21, and the condenser blower 22 are housed and installed on the unit base 18. The cooler 13 in the display unit 2 is connected to the compressor 19 and the condenser 21 in the unit unit 3 by a refrigerant pipe 23 (with two paths) that passes through the connecting portion 4A of the heat insulating wall 4. A known refrigerant circuit of the cooling unit 12 is configured by connecting the pressure reducing devices not to be annular.

  In the embodiment, the compressor 19 having the heaviest weight is arranged at the front part (one end part) of the unit base 18, the condenser 21 is located at the rear part (the other end part), and the condenser blower 22 is interposed between them. Has been placed. The periphery of the machine room 20 of the unit portion 3 is covered with a casing 24, and a plurality of vent holes 26 (shown in the perspective view of FIG. 3) are formed on the front surface, side surface, rear surface, and bottom surface of the casing 24. Has been. A drain pan (not shown) is provided in the unit portion 3. Drain water from the cooling chamber 11 of the display unit 2 is discharged into a drain pan from a water pipe (not shown) that passes through the connecting portion 4A and is evaporated.

  Further, the upper surface 24A of the casing 24 is located below the bottom surface 4B of the heat insulating wall 4 so as to be separated from the front surface and the left and right (one end and both sides) between the display unit 2 and the unit unit 3. A table mounting portion 27 is configured. The vertical dimension of the table mounting portion 27 is set to a sufficient value even when a thicker table plate is inserted than usual, and is 140 mm in the embodiment.

  A mounting bolt 28 is screwed onto the upper surface 24A of the casing 24 and protrudes to the table mounting portion 27 side. In the embodiment, the position of the mounting bolt 28 is on the left and right sides of the substantially central portion of the upper surface 24A in consideration of operability. The mounting bolts 28 are not limited to the two in the embodiment, and may be provided at the four corners (four) of the upper surface 24A. Further, leg portions 29 made of hard rubber or resin are attached to the four corners of the bottom surface 4B of the heat insulating wall 4.

  When the compressor 19 in the unit section 3 is operated, the high-temperature and high-pressure refrigerant discharged from the compressor 19 is cooled by the condenser 21 by the condenser blower 22 and condensed. The outside air for air-cooling the compressor 19 and the condenser 21 flows into the machine room 20 from the vent 26 on the rear surface of the casing 24 and is discharged from the vents 26 on the left, right, bottom, and front surfaces. The condensed refrigerant reaches the display unit 2 through the refrigerant pipe 23, is throttled by a decompression device (an expansion valve or a capillary tube) (not shown), and then flows into the cooler 13 and evaporates. The cooling effect is exhibited by the heat absorption at this time. The refrigerant exiting the cooler 13 returns to the unit section 3 through the refrigerant pipe 23 and repeats circulation sucked into the compressor 19.

  When the blower 14 is operated, the cool air in the cooling chamber 11 cooled by exchanging heat with the cooler 13 is discharged from the cool air discharge port 16 in the opening direction (front) of the display chamber 9 to form an air curtain in the opening. While circulating into the cool air suction port 17 and returning into the cooling chamber 11, the circulation is repeated. A part of the cool air forming the air curtain circulates in the display chamber 9 and cools goods (such as beverages) in the display chamber 9. Further, the compressor 19 is operated and controlled so as to maintain the temperature in the display chamber 9 at a predetermined refrigeration temperature, whereby the products in the display chamber 9 are displayed while being cooled to the predetermined temperature.

  Next, the installation method of the low-temperature showcase 1 of this invention is demonstrated. First, for example, when a product is displayed and sold on a counter table (table) CT of a store, as shown in FIGS. 1 and 2, the attachment is performed in a table attachment portion 27 between the display portion 2 and the unit portion 3. The display unit 2 is placed on the upper surface of the counter table TC in such a manner that the counter table TC is inserted from the front side of the unit 27. In this case, the counter table TC is inserted into the table mounting portion 27 until it approaches or comes into contact with the connecting portion 4A.

  Next, the mounting bolt 28 is rotated to raise its upper surface, and is brought into contact with the lower surface of the counter table TC and tightened. Accordingly, the counter table TC is sandwiched between the display unit 2 and the unit unit 3 (the mounting bolt 28), and in the embodiment, the low temperature showcase 1 is detachably attached to the counter table TC. At this time, the unit unit 3 is located and stored below the counter table TC. That is, in this attached state, the display section 2 including the display chamber 9 is divided on the counter table TC, and the unit section 3 including the compressor 19 of the cooling unit 12, the condenser 21 and the like is divided below the counter table TC. Installed.

  As a result, the occupied space on the counter table TC can be reduced. In particular, since the unit unit 3 in which the compressor 19 and the like are installed is stored below the counter table TC, the height of the display chamber 9 is set to a low position even when the counter table TC is high. Can be suppressed. Thereby, it becomes possible to ensure the ease of taking out the product.

  When the low temperature showcase 1 is moved, the low temperature showcase 1 can be easily detached from the counter table TC by loosening the mounting bolt 28 and lowering the upper surface thereof and separating it from the lower surface of the counter table TC. The position can be moved. That is, in the present invention, since the display unit 2 and the unit unit 3 are integrated, the installation work and the moving work are facilitated, and the advantages of the so-called desktop type low temperature showcase can be maintained.

  In particular, in this embodiment, a cooler 13 is provided in the cooling chamber 11 of the display unit 2, and the cooler 13 and the compressor 19 in the unit unit 3 are connected by piping. Here, when a cooler is provided in the unit part 3, it is necessary to surround the cooler in the unit part 3 with a heat insulating wall. However, the cooler 13 is arranged in the display part 2 as in this embodiment. If it is provided on the side, such a heat insulating structure is not required, and the overall size can be reduced.

  When not installed on the counter table TC as shown in FIG. 1 or FIG. 2, the plate-like table T is inserted into the table mounting portion 27 as shown in FIG. If attached, a low-temperature showcase having a table T between the display unit 2 and the unit unit 3 can be configured.

  In the above embodiment, the cooler 13 is provided in the cooling chamber 11 of the display unit 2. However, the present invention is not limited thereto, and the cooler 13 and the blower 14 may be provided in the unit unit 3. In that case, the heat insulation box is accommodated in the unit part 3, and the cooling chamber 11 is comprised in this heat insulation box. And while accommodating the cooler 13 and the air blower 14 in this cooling chamber 11, the duct part of a 2 system path is comprised in the connection part 4A, on the other hand, the cold air discharge side (on the cooling chamber 11 in this heat insulation box body ( The cool air outlet side of the cooler 13 and the cool air discharge port 16 of the display unit 2 communicate with each other, while the cool air suction port 17 of the display unit 2 and the cool air suction side of the cooling chamber 11 in the heat insulating box (the cool air suction side of the blower 14). ).

  Then, the cool air in the cooling chamber 11 that exchanges heat with the cooler 13 in the heat insulating box of the unit portion 3 is sent to the cool air discharge port 16 of the display unit 2 through the duct, and discharged from the cold air discharge port 16 to be displayed in the display chamber 9. Cool inside. And the cool air circulation which draws in the cool air in this display room 9 from the cool air suction inlet 17, and returns to the air blower 14 in the heat insulation box of the unit part 3 through a duct is comprised.

  With such a configuration, it is not necessary to configure the cooling chamber 11 below the display chamber 9 as in the above-described embodiment, so that the height of the transparent wall 6 is made lower if the volume of the same display chamber 9 is the same. This is extremely suitable for installation in stores where the height of the counter table TC is high.
