ンシヨーケースの背面吹出し装置。 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 an open cold air circulation case that forms a cold air curtain at the opening by drawing air in, a hole is provided at the back of the inner box for communication between the inside of the inner box and the cold air ventilation path, and air is blown through the hole. A back blowing device for a cold air circulation type open show case, characterized by being provided with an air guide that guides the blowing direction of cold air upward parallel to the back surface of the inner box or upward at an acute angle with the back surface.
