The partition 4 is made of plastic or the like, and is provided with a substantially inverted L-shaped upper rib 8 forming a fitting groove 7 at the front, and is fitted to an upper plate 9 constituting the upper surface of the partition 4 at the front. A lower plate 10 which constitutes a lower surface of the partition body 4 and a lower plate 11 which constitutes a lower surface of the partition body 4 are provided.
A heat insulating body 12 is accommodated between the lower plate 11 and a front plate 14 having a U-shaped cross section and having a flange 13 fitted in the fitting groove 7.

A hot pipe 15 for preventing dew is disposed between the front plate 14 and the heat insulating body 12, and the hot pipe 15 sufficiently contacts the front plate 14 to sufficiently transfer heat and to prevent heat from being transmitted to the inside of the refrigerator. In order to prevent low temperature from being transmitted to the front plate 14, a heat insulating material 17 made of aluminum foil 16, soft urethane foam or the like is interposed between the hot pipe 15 and the heat insulator 12.

At the rear of the lower plate 11, a gutter section 18 for collecting defrost water flowing down from an evaporator (not shown) disposed behind the freezer compartment 5, and a lower part of the gutter section 18 A drain port 19 for drainage is integrally formed. A drain pipe 20 is connected to the drain port 19, and the defrost water flowing down from the evaporator is drained from the drain pipe 20.
Through the evaporating dish below the refrigerator (not shown).

A front surface of the fitting groove 7 on the substantially inverted L-shaped rib 8 of the upper plate 9 is provided between the left and right ends of the upper plate 9 and has an upper end formed by a flange of the front plate 14. A weir 21 is provided to abut on the inner surface of 13, and the weir 21 is formed integrally with the heat insulator 12,

A drain hole 23 communicating with the upper surface of 11 is provided by cutting out the heat insulator 12.

In the above configuration, when water, drinks, etc. are spilled on the front surface of the upper plate 9 in the refrigerator, the water flows into the flange of the upper plate 9 and the front plate 14 as shown by the arrow in FIG. 13 and flows into the upper surface of the heat insulator 12. The flowing water does not flow to the hot pipe 15 side by the weir 21, but is collected in the concave portion 22 on the back surface of the rib 8, passes through the drain hole 23, and
Flows over the top of The surface of the heat insulator 12 is rough and expands and contracts depending on the temperature, so that a gap is formed between the heat insulator 12 and the lower plate 11, so that water discharged from the drain hole 23 flows into the gutter portion 18 from this gap, The water is drained from the drain pipe 20 through the drain port 19 to the evaporating dish. As a result, it is possible to prevent the intrusion of water and the like into the hot pipe 15 side, and to provide a refrigerator capable of preventing corrosion of the hot pipe 15.
