[0002]

2. Description of the Related Art Conventionally, a method of inserting dry ice has been used as a means for preserving the bodies contained in the casket. However, dew condensation locally occurs on the outer wall surface of the casket in contact with the dry ice. There is a problem that dry ice causes a feeling of strangeness when it occurs or when fresh flowers are displayed around the body.

Further, since dry ice is difficult to burn, it has to be taken out from the coffin when it is to be cremated, which is extremely complicated. Furthermore, there is a problem that dry ice must be frequently replenished in hot and humid conditions such as in the summer or in a heated room.

In view of this, in Japanese Patent Laid-Open No. 4-244153 (A61G17 / 04), a cooling device having a refrigerating cycle is attached to a heat insulating box body having a size capable of accommodating a casket, and the heat insulating box is installed. A cooling system has been developed in which a casket is stored inside a box.

When the cooler 1 is operated with the above configuration,
Condensation occurs on the inner surface of the heat insulating material 4 due to the cooling action of the thermoelectric element 16, but this condensed water (hereinafter referred to as drain water) is discharged through the drain pipe 17 and stored in the drain pan 62. The good water-absorbent member 63 has a lower part soaked in drain water and an upper part exposed to the water surface. Therefore, the drain water in the drain pan 62 is sucked up by the good water-absorbing member 63 due to the capillary phenomenon, and evaporates from its wide surface.

In particular, at this time, warm air heated by the radiation fins 23 (air that has cooled the heat-generating portion 16B) is blown from the blower 24 to the drain pan 62 (good water-absorbing member 63), so that the area is enlarged. And the supply of warm air cause the drain water in the drain pan 62 to be absorbed by the good water-absorbing member 63.
Actively evaporates from the surface and the surface of the drain water itself. Therefore, according to this structure, the drain water in the drain pan 62 can be quickly treated.
