程度とするとよい。(20) is a plate-shaped evaporation member composed of a hydrophilic perforated plate such as Univex (trade name) SB which constitutes an evaporation device together with the evaporation tray (13). Fine-grained phenol is heat-cured to form a sticking agent, which is then dipped in an alcohol solvent to obtain a capillary action and then dried. Because of its fibrous nature, it is bendable and bendable. It has a repulsive force against. As shown in FIGS. 4 and 5, the evaporation member (20) includes a plurality of bent portions (21) and valleys (2).
2) and the inclined portion (23) are bent in a meandering manner a plurality of times to be arranged in the evaporation dish (13). Further, an air passage (24) is formed in the peak portion (21) and the valley portion (22), and this is formed by pressing when it is plate-shaped as shown in FIG. . In addition, the smaller the dimension (a) between the ventilation passages (24), the better the dimension (a) is 4-5 [mm].
It is good to set it as a degree.

る。With the above configuration, as shown by the arrows in FIGS. 1 and 2,
The evaporation device is arranged in the machine room (5), and as the air is blown by the blower (12), the evaporation of the defrost water (W) sucked up by the capillary action is promoted and the evaporation member (20) Increase evaporation. At this time, as part of the wind passes through the ventilation path (24), the wind hits both sides of the evaporation member (20), and the contact time of the wind with the evaporation member (20) becomes longer. In addition, because the resistance of the wind passing through the air passage (24) changes, turbulent flow occurs near the air passage (24),
Due to this turbulent flow, the contact time of the wind with the evaporation member (20) is further lengthened, and the temperature in the vicinity of the ventilation path (24) of the evaporation member (20) can be maintained high, that is, the temperature decrease can be largely prevented.

果が得られる。Also, since the evaporation member (20) has a repulsive force, it is a member that is very difficult to bend, but by forming the ventilation passage (24) in the bent portion, the bent portion becomes shorter, Since the repulsive force is weak in the bent portion, it is easy to bend. Further, when the evaporating member (20) is stretched into a plate shape and washed, and then placed in the evaporating dish (13) again, the evaporating member (20) can always be bent at a fixed position. Therefore, the best evaporation effect can always be obtained by forming the ventilation path (24) at the position where the evaporation effect is most likely to occur first.

できると共に、単位時間当たりの蒸発量を多くできる。(G) Effect of the Invention According to the above-described evaporation device of the present invention, since a part of the air blown from the blower passes through the ventilation passage, the contact area of the wind with the evaporation member increases, and turbulence occurs near the ventilation passage. A flow is generated, and the contact time of the wind with the evaporating member is lengthened. As a result, water can be evenly evaporated and evaporated from the evaporating member, and the evaporation amount per unit time can be increased.
