Claims

[Scope of utility model registration request]

A plurality of ventilation passages are formed by providing a partition wall between an outer box having a generally U-shaped cross section and an opening at the front, and an inner box forming an inside of the refrigerator, and each ventilation passage has the opening at both upper and lower ends. In the cold air circulation type open show case, which has a blowout port and a suction port facing the wall, and each has a fan therein, the fan blows out a plurality of layers of air curtain to the opening. At both ends of the ventilation passage, the space between the outer box and the inner box is partitioned into the inside and outside to form an inside and outside ventilation passage, and at the middle part of the ventilation passage, the space between the outer box and the inner box is partitioned into the inside and outside. The box is divided into three in the longitudinal direction to form a central and side ventilation passage, and the outside ventilation passage and the central ventilation passage are connected and communicated with the inside ventilation passage and the side ventilation passage, respectively. A cold air circulation type open case, characterized in that the plurality of ventilation passages are formed.
