The accumulator 36 is connected to the bottom of the compressor 33, and the refrigeration cycle S is configured as described above.

  This is an open showcase configured as described above. By driving the compressor 33 and driving the outside air blower 37 and the cold air blower 31, the refrigerant is compressed by the compressor 33, and the condenser 34 is converted into a high-temperature and high-pressure gas refrigerant. Led to.

  The outside air blower 37 takes outside air into the machine room M and blows it to the condenser 34 through the vent hole 7 provided in the lower part of the showcase body 1. In the condenser 34, the gas refrigerant is condensed and liquefied by exchanging heat with the outside air blown from the outside air blower 37.

  The outside air led to the condenser 34 flows through the compressor 33 and the accumulator 36, cools them, and then is led out to the outside of the showcase body 1 through the vent hole 7 provided in the opposing surface portion.

  On the other hand, the liquid refrigerant led out from the condenser 34 adiabatically expands in the expansion valve 35 and is led to the evaporator 30 disposed in the bottom ventilation path 25 which is the bottom of the first and second display chambers 1R and 2R. .

  Since the air is blown from the cold air blower 31 to the evaporator 30, the refrigerant evaporates by exchanging heat with the air blown in the evaporator 30. At this time, the refrigerant takes the latent heat of evaporation from the air guided by the cold air blower 31 and lowers the temperature. The evaporated refrigerant is led to the accumulator 36 to be gas-liquid separated, and only the gas component is led to the compressor 33 to be compressed and circulates in the above-described system path.

  The air blown by the cold air blower 31 and circulated through the evaporator 30 to lower the temperature, that is, the cold air is led out from the bottom ventilation passage 25, and the lower end openings of the first duct portion 11 and the second duct portion 12, respectively. The inside of each duct 11 and 12 rises.

  In the middle of the ascending, the cool air is blown out from the display chamber outlet 20 opened between the display shelves 17 of each stage in the first display chamber 1R and the second display chamber 2R. Therefore, the inside of each display room 1R, 2R is kept at a low temperature, and the products on the display shelf 17 in each display room 1R, 2R are cooled.

  The cool air reaching the upper end portions of the first duct portion 11 and the second duct portion 12 is guided to the upper ventilation path 21 communicating with the respective duct portions 11 and 12. And it blows off toward the downward direction from the blowout opening 24 for air curtains formed in the one end part of the upper ventilation path 21. FIG.

  The cool air is blown down from the front upper ends of the first display chamber 1R and the second display chamber 2R, and is opened along the first surface a and the third surface c that are the front surfaces of the display chambers 1R and 2R. It flows down and forms a cold air curtain.

  In the middle of the flow, the cool air is conducted through the gap between the end of each display shelf 17 and the rectifying plate 9, and the rectifying plate 9 rectifies the cold air. And finally, it guide | induces along the bottom ventilation path 25 from the cold air inlet 28 opened to the bottom part of each display chamber 1R, 2R, and circulates the above-mentioned system path.

  In the first display chamber 1R and the second display chamber 2R, the cool air is blown out from the display chamber outlet 20, and the cool air is blown out from the air curtain outlet 24 to thereby front the display chambers 1R and 2R. A cold air curtain is formed in each of the display chambers 1R and 2R to sufficiently lower the temperature.

Since it comprises using a member, the goods displayed by the other display room 2R / 1R from the one display room 1R / 2R side can be seen.

  Therefore, the open showcase according to the present invention can perform an exhibition with a sense of volume, and the display effect is improved. At the same time, it is possible to obtain product management benefits such as inventory check.

  Since it is a four-sided open type, there is substantially no rear side, and since the arrangement area is compact, it is not necessary to be restricted by the arrangement place in the store. As a showcase, there is no closed back side, and products can be displayed on both the front and rear sides and can be freely taken out, so that the display efficiency can be doubled compared to the current front open type showcase.

  A first duct portion 11 is provided in the first display chamber 1R, and a second duct portion is provided in the second display chamber 2R, with a partition plate 10 that divides the interior of the showcase body 1 into two front and rear chambers. Since 12 is provided, the strength of the showcase body 1 which is a housing can be improved.

  The cold air flowing vertically upward from the lower part of the showcase body 1 can be evenly flowed uniformly between the front side and the rear side. Since the air curtain is formed so that the door is not opened and closed, even when the product is frequently taken out, the cooling efficiency is not lowered in each of the display rooms 1R and 2R, and the best cooling effect can always be obtained.

  The partition plate 10 and the first and second duct portions 11 and 12 are made of a heat insulating material so that the first display chamber 1R and the second display chamber 2R are not affected by heat. Since each display room 1R, 2R has heat insulation performance, the occurrence of dew condensation on the surface of each duct part 11, 12 is prevented due to the temperature difference between the front side and the rear side, thereby reducing the product value of the displayed products. Stop.
