Claims

[Scope of utility model registration request]

A cold air circulation path is formed in a main body case having a U-shaped cross section with an opening at the front and a door at the opening, and whose upper and lower ends face the opening on the inside of the door and form a cold air outlet and an inlet, respectively. A fan and a cooler are disposed in the cold air circulation path, and the fan circulates the air inside the refrigerator through the cooler to cool the interior of the refrigerator, and also stops the flow of refrigerant to the cooler. In a refrigerated case with a front door that defrosts air by circulating uncooled air using the fan, a variable speed motor is used as the fan motor of the fan, and the fan motor is linked to the opening and closing of the door, and when the door is opened, the cooling air is removed. 1. A refrigerated case with a front door, characterized in that the flow of refrigerant to the container is stopped and the fan is operated at high speed.
