[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator,
In particular, the present invention relates to a structure of a partition panel on an inner wall of a freezer compartment and a mounting structure of the automatic icemaker in a refrigerator with an automatic ice making device having a convex portion on a ceiling surface of the freezing room.

[0002]

2. Description of the Related Art FIG. 11 shows a conventional refrigerator with an automatic ice making device. This refrigerator has a refrigerator compartment 3 and a freezer compartment 5 partitioned vertically by a partition wall 1, and a recess 9 in which a water supply tank 7 for ice making is arranged on the side of the refrigerator compartment 3.
Are formed. Due to the concave portion 9, the convex portion 13 is present on the ceiling surface portion 11 of the freezer compartment 5, and the automatic ice making device 15 is installed behind the convex portion 13. The automatic ice making device 15 is attached by inserting the automatic ice making device 15 from the front of the freezer compartment 5 behind the convex portion 13 of the partition wall 1 and fixing the automatic ice making device 15 to the partition wall 1 and the like with screws (not shown). Is being done.

FIG. 12 shows a conventional refrigerator with an automatic ice making device of a forced air circulation type. The refrigerator has a cooler (heat exchanger) 17 at the back of the freezer compartment 5, and a blower fan 19 for blowing out cool air is provided in front of the cooler 17.
Is disposed. Partition panel 21
Is a panel with a fan grille that also serves as a partition from the cooler arrangement portion, and is formed entirely of a single panel structure, and is located substantially behind the convex portion 13 of the partition wall 1 in the freezer compartment 5. It has a wall.

To assemble the partition panel 21, the lower end 21 a of the partition panel 21 is inserted first into the lower rear side of the freezer compartment 5, and the lower end 21 a is formed in the lower rear wall 25 of the freezer compartment 5.
