Claims

[Scope of utility model registration request]

A case body having an opening on one side is constituted by an outer box and an inner box each having a U-shaped longitudinal section, and one of the ends facing the opening serves as a cold air outlet and the other serves as a cold air intake port. A ventilation path is formed between the outer box and the inner box of the case body, and the cooler and blower installed here blow out cold air from the outlet through the cold air ventilation path, and then blow it out from the intake port. In a cold air circulation type open store case that forms a cold air air curtain at the opening by suction, a plurality of rows of holes communicating with the cold air ventilation path in the warehouse formed inside the inner box are provided on the back of the inner box, and the rows of holes are provided on the back of the inner box. The cold air is characterized by having a number of shelves greater than the number of product display shelves provided vertically in the refrigerator, and an opening adjustment device for adjusting the opening degree of the communication hole by operating from inside the show case refrigerator. Rear air blowing device for circulation open case.
