を蒸発皿に導いて蒸発させる構造である。(Prior Art) Conventional refrigerators, such as those seen in Electrolux's product number RE-800 (released in April 1989), use so-called defrosted water (hereinafter referred to as defrost water). To evaporate, attach the defrost water evaporation tray closely to the high-temperature, high-pressure pipe installed at the bottom of the refrigerator.
The drain tray, which is molded integrally with the inner box of the refrigerator, has a drain guide that penetrates the refrigerator wall and guides defrost water out of the refrigerator, and is in close contact with the drain hole of the tray, and a drain hose is connected to it to allow the defrost water to evaporate. It has a structure that leads it to a dish and evaporates it.

Frost that adheres to the cooling pipe 11 and the heat conductive plate 12 during cooling can be removed by turning off the bush switch 14 of the thermostat 13, which simultaneously turns off the power to the heater 15 for refrigerant circulation, stopping cooling and removing the frost. Clearing is started, the frost is naturally melted, and the frost tray at the upper part of the inner box 3 falls into the tray 5 as water. The water is guided from the drain hole 6 of the frost tray 5, through the drain guide 7, to the evaporation tray 10 by the drain hose 8, and the defrost water that accumulates in the evaporation tray 10 is naturally heated by the high temperature and high pressure pipe 9. It will be evaporated.

れ溢れ出る問題があった。(Problems to be Solved by the Invention) In the conventional refrigerator defrost water evaporation device as described above, the evaporation dish 10 has poor heat conduction efficiency with the high temperature and high pressure pipe 9, so the water evaporation capacity is small, and therefore , defrosting water will remain in the evaporating dish 10, and if you open and close the refrigerator door frequently in a high-temperature, high-humidity room, the cooling pipe 11 and heat conduction plate 1 will be damaged.
There was a problem in that a large amount of frost adhered to the evaporating tray 2, and the defrosting water flowed directly from the drainage hole 6 of the tray 5, through the drain hose 8, and overflowed into the evaporating tray 10.
本発明は上記従来の冷蔵庫の問題点に鑑み、霜とり水が
溢れない蒸発装置の提供を目的とする。In view of the above problems of conventional refrigerators, the present invention aims to provide an evaporator that does not overflow with defrosting water.
