る冷気循環形オープンシヨーケース。 A cold air circulation path containing a cooler, a fan, and a heater is formed between an outer box and an inner box of the main body case having an opening on the front or top surface, and during cooling operation, the cold air is circulated through the cooler by the fan. The cold air flow forms an air curtain in the opening and cools the inside of the display room, and during defrosting operation, the cold air is defrosted by the warm air flow that is heated by the heater and made to flow through the cold air circulation path by the fan. In the circulation type open shower case, the heater is provided in at least two places, one on the air inlet side of the cooler and the other in the center, and
A cold air circulation type open shower case characterized by being provided with a changeover switch for selectively energizing both of the heaters during defrosting operation.
