Claims

[Scope of utility model registration request]

A refrigerant evaporator is placed in the upper or lower part of the refrigerator, a ventilation path including the refrigerant evaporator is formed by an internal circulation fan, and at least one hole is provided to communicate between the inside and outside of the refrigerator. After passing the connected outside air suction pipe into the refrigerant evaporator or contacting or adhering a part of the pipe to the compressor suction pipe, the end of the pipe is connected to the inside circulation fan. In a forced circulation type high-humidity refrigerated showcase set on the suction side, a small hole is provided in addition to the above-mentioned hole to communicate between the outside and the inside of the refrigerator, and a fan exclusively for exhaust is provided opposite the small hole. High humidity refrigerated showcase.
