Claims

[Scope of utility model registration request]

The inner and outer double inner and outer ducts that form the circulation ventilation path are separated between the outer box and the inner box of the open-front case body, and the inner duct is equipped with a cooler and an inner fan.
The outer duct houses an outer fan, and operates the cooler and each fan during cold storage operation to form a two-layer cold air curtain inside and outside the front opening of the case body through each duct, and during defrosting operation, the outer fan is In an open showcase in which the outside air sucked in from the air curtain outlet of the outer duct by running the fan in reverse is reversed from the air curtain inlet and sent into the inner duct to defrost the cooler, the open end of the air curtain inlet A ventilation window that communicates between the two ducts is opened in the partition wall that partitions the inner duct and the outer duct in the vicinity, and a wind direction vane is provided above the ventilation window that projects from the partition wall into the outer duct at an acute angle. Features an open showcase.
