Claims (1)

[Scope of Claim for Utility Model Registration] (1) A cold air inlet that communicates with a cold air blowing means including an evaporator provided on the back plate of the freezer compartment and a duct attachment port that communicates with the refrigerator compartment. At the same time, a partition plate having a cold air outlet is provided on the front side of the back plate to form a cold air distribution chamber therebetween, and the cold air from the cold air blowing means is passed through the cold air distribution chamber to the freezer compartment. In an electric refrigerator of a forced circulation type that supplies cold air to both the refrigerator compartment and the refrigerator compartment, a flange bent at a substantially right angle toward the inside of the freezer compartment is connected to the lower end of the back plate, and the flange is An electric refrigerator characterized in that the electric refrigerator is airtightly joined to the inner box formed on the bottom wall of the freezer compartment. (2) In claim (1) for utility model registration, the above-mentioned partition plate consists of a plate-shaped body large enough to cover almost the entire surface of the above-mentioned back plate, and the above-mentioned cold air outlet is provided at the upper and lower parts of the partition plate, respectively. An electric refrigerator characterized in that the electric refrigerator is provided with a flange formed at a lower end thereof to be superimposed on the flange of the back plate. (3) The electric refrigerator according to claim (1) for utility model registration, characterized in that the inner box has a protrusion for positioning the flange of the back plate between it and the evaporator. . (4) In claim (2) for utility model registration, between the flange of the back plate and the flange of the partition plate,
An electric refrigerator characterized in that it is provided with engagement means consisting of a combination of a locking piece and an engagement hole.
