Ｅから水と共に吹きこぼれてしまう。 Generally, a water resistor is used as a dummy load for a large power generator. As shown in FIG. 1, electrodes B are inserted facing each other into water in a water tank A, and power is consumed by increasing the temperature of the water due to the electrical resistance of the water. In this case, the water storage tank A is provided with a water supply port C and a drain port D, and since water is continuously supplied and drained, an abundance of high-quality water is required. However, in places such as desert areas where abundant water cannot be expected, the water tank is sealed and the water is vaporized without being drained.
If water is supplied in a timely manner, the amount of water supplied will be about 1/50 of the amount in the above case. However, in this case,
As shown in Figure 2, when the water in the water tank A boils and the upper space becomes hot and humid, the water bubbles caused by the boiling are not destroyed and fill the upper space, and eventually boil over violently from the exhaust port E along with the water. It ends up.

以下第３図について本考案の一実施例を説明す

つながる電極２が上下に対向するように挿入され
ている。 An embodiment of the present invention will be described below with reference to FIG. Electrodes 2 connected to a generator G are inserted into the water in a closed water tank 1 so as to face each other vertically.

る。水の温度がさらに上昇して沸騰を始めても、
上部空間が送風により除湿、冷却されているため
水泡は瞬時に破壊され、充満することがない。 Next, the action will be explained. Electric power generated from the generator G is consumed as an increase in water temperature due to the electrical resistance of the water. The water vaporizes in the upper space of the water storage tank, and the temperature of the upper space rises, but it is constantly cooled by the cold air from the air outlet 5, and the water vapor is discharged to the outside from the exhaust port 6. Even if the water temperature rises further and begins to boil,
Since the upper space is dehumidified and cooled by air blowing, blisters are instantly destroyed and do not become full.

な量でよい。 The amount of air blown needs to be adjusted appropriately depending on the amount of power consumed by the water resistor and the capacity of the water tank 1, but in short, the amount that can keep the humidity in the space 7 above the water surface below the saturation point is sufficient. However, only a small amount is sufficient.
