Claims

[Scope of utility model registration request]

A cold air ventilation path and an air ventilation path are formed with a partition plate between the outer box and the inner box of the case body, which have an opening on one side. are formed with an air outlet and an air inlet each having a flow regulator facing the opening, and the air outlet of the cold air ventilation path is provided protruding from the air outlet of the air ventilation path, and the air outlet of the cold air ventilation path is provided. A cold air circulation type in which a cold air curtain and a protective air curtain are formed in the opening between the blow-off port and the suction port by operating a cooler and a blower provided in the air passage, and a blower provided in the air ventilation path. In the open show case, a ventilation hole is provided in the partition plate in front of the outlet of the cold air ventilation path to introduce a part of the cold air from the cold air ventilation path into the air outlet of the air ventilation path, and this part of the cold air is removed from the air. A cold air outlet condensation prevention device for a cold air circulation type open show case, characterized in that the air flows along the surface of the end of the partition plate exposed outside the outlet of the ventilation path.
