  FIG. 1 also shows a back part 4a of the freezer compartment 4 which is the inner wall of the refrigerator. Although the back part 4a of the freezer compartment 4 is also a part of the inner box 1b, a concave part 30 having a small depth is formed in the central part of the inner box 1b, and the back part of the defrost water discharge rod 28 is formed in the concave part 30. The side part 28c is accommodated. Accordingly, the defrosting water discharge rod 28 is disposed with the remaining portion 28d (particularly both the left and right sides of the portion 28d) protruding from the inner wall (the back of the freezer compartment 4) 4a into the chamber. The rail mechanism 29 overlaps the protruding portion 28d of the defrost water discharge rod 28 in the depth direction. That is, the length of the rail mechanism 29 is a length that overlaps the protruding portion 28d of the defrost water discharge rod 28 in the depth direction.

  In addition, although the heat insulation wall of the store | warehouse | chamber main body 1 becomes thin in the inner part with the elongate of the rail mechanism 29, although not shown in detail in the heat insulation wall, the heat insulation material 1c has the vacuum heat insulation excellent in heat insulation performance. The panel is used together with a foam heat insulating material such as foamed polyurethane, or alone, so there is no deterioration in heat insulation performance. Moreover, the vacuum heat insulation panel is used also in the both right and left sides of the storage body 1 heat insulation wall.

  And the heat insulation part 31 is provided in the outer side of the said protrusion part 28d of the defrost water discharge rod 28. FIG. In this case, as shown in FIG. 4, the heat insulating portion 31 is provided by forming an outer wall 31 a continuous with a predetermined distance from the protruding portion 28 d outside the protruding portion 28 d of the defrosting water discharge rod 28. The defrosting water discharge rod 28 is connected to the upper surface and the front surface, and has a rectangular bag shape with the lower surface and the rear surface opened. However, in a state where a part 28c of the defrost water discharge rod 28 is housed and disposed in the recess 30, the open portion of the lower surface of the outer wall 31a is in contact with the bottom 18a of the cooler chamber 18 as shown in FIG. As shown in FIG. 1, the open portion on the rear surface is closed in contact with the inner portion 4 a of the freezer compartment 4.

As a result, air is contained inside the outer wall 31 a, and the outside of the protruding portion 28 d of the defrost water discharge rod 28 is insulated by the contained air so that the heat insulating portion 31 is formed.
In addition, as shown in FIG. 4, although the front edge part of the defrost water discharge rod 28 has the upper edge part parallel to the inclination shape of the above-mentioned inner bottom face, the rear edge part has an upper edge part on another surface. It has the same non-inclined shape as the upper edge of both the left and right side surfaces.

The outer wall 31a is integrally formed with the defrost water discharge rod 28 by plastic molding.
Further, a plurality of ribs 32 reaching the outer wall 31a from the protruding portion 28d are provided between the protruding portion 28d of the defrosting water discharge rod 28 and the outer wall 31a. The rib 32 is also formed integrally with the defrost water discharge rod 28 by plastic molding, that is, provided integrally with the defrost water discharge rod 28 and is also integrated with the outer wall 31a. .
In addition, the rib 32 is provided from the upper surface portion to the lower end portion of the outer wall 31a, and at the same time, provided from the lower edge portion of the protruding portion 28d of the defrost water discharge rod 28.

Next, the function and effect of the refrigerator having the above configuration will be described.
In the refrigerator having the above-described configuration, the defrost water discharge rod 28 is provided so as to protrude into the chamber, but since the heat insulating portion 31 is provided outside the protruding portion 28d, the inside of the refrigerator and the protruding portion 28d are separated from each other. The space is insulated and insulated by the heat insulating portion 31. For this reason, it is avoided that the inside air touches the protruding portion 28d directly, and the inside air is not cooled via the protruding portion 28d by the cool air in the defrost water discharge rod 28 by the cooler 20. . Thereby, dew condensation and icing outside the protruding portion 28d can be prevented.

Further, in the refrigerator having the above-described configuration, the heat insulating portion 31 is provided on the outside of the protruding portion 28d of the defrosting water discharge rod 28 by forming an outer wall 31a continuous with a predetermined distance from the protruding portion 28d. The required heat insulation can be reasonably obtained by the air in the outer wall 31a.
However, a heat insulating material such as polystyrene foam may be loaded in the outer wall 31a, and the heat insulating portion 31 itself and the heat insulating material such as polystyrene foam may be attached to the outside of the protruding portion 28d of the defrost water discharge rod 28. It may be provided.

  Further, in the refrigerator having the above-described configuration, the rib 32 reaching the outer wall 31a from the protruding portion 28d of the defrosting water discharge rod 28 is provided so that the outer wall 31a can be reinforced and the outer wall 31a is not deformed such as a dent. Therefore, the heat insulating part 31 can be held in a fixed shape, and as a result, the desired heat insulating action can be obtained more reliably.

In addition, in the refrigerator having the above-described configuration, the rib 32 is provided by integral molding with the defrost water discharge rod 28, thereby eliminating the trouble of separately creating and attaching the rib 32. The sex can be improved.
And in the refrigerator of the said structure, since the rib 32 is provided over the lower end part of the outer wall 31a, the reinforcement effect | action of the above-mentioned outer wall 31a can be increased by this, and the heat insulation part 31 can be hold | maintained more firmly and fixedly, The thermal insulation effect of the period can be obtained more reliably. In this case, the rib 32 may be provided separately from the defrost water discharge rod 28.
