Description

[Detailed Description of the Invention] This invention relates to a device that efficiently generates steam with little electric power.

Conventionally, it is known that each of a pair of electrodes is cylindrical, and one cylinder is placed inside the other cylinder so that they face each other.

However, in this case, when bubbles are generated between the two electrodes, that is, between the two cylinders, there is no way for them to escape, and they all rise between the cylinders.

Therefore, there are many air bubbles between the cylinders, and these air bubbles have the disadvantage of decreasing thermal efficiency.

In addition, since there is a large amount of water in deep water areas, it is not possible to boil the water sufficiently, resulting in an increase in power consumption.

This invention eliminates the above-mentioned conventional drawbacks, and will be described below with reference to the illustrated embodiments.

The steam generator of this embodiment has a pair of electrodes 2 and 3 built into its tank 1, and the shapes of these electrodes are as shown in FIG. 2.3.

That is, each of these electrodes consists of three rings 4.5, and these rings 4 and 5 are connected by support pieces 6 and 7 to maintain a required distance in the vertical direction.

When looking at the overall state in which the three rings are connected, it forms a funnel shape that becomes smaller in diameter as it goes downward.

In addition, the ring 5 of the other electrode 3 is made smaller in diameter than the ring 4 of one electrode 2, so that the other electrode 3 fits completely into the one electrode 2, and each ring 4, 5 maintains a constant spacing. We have a relationship where we face each other.

The electrodes 2 and 3 as described above are installed on the bottom plate 9 of a support tube 8 made of an insulator provided in the tank 1, and the lower side of this support tube 8, that is, the wall surface surrounding the electrode of this invention. is funnel-shaped to fit each ring of the electrode.

A water intake port 10 is formed in the center of the bottom plate 9,
Water introduced from the inlet 11 is guided into the support cylinder 8 from this inlet.

Note that the reference numeral 12 in the figure is a heat insulating material, and the lower part thereof is also funnel-shaped like the support tube 8.

However, when the electrical connection end led from the insulator 13 into the tank 1 is connected to the support pieces 6 and 7 and energized, the water between the rings 4 and 5 becomes a resistance and generates Joule heat. The water between the rings boils and produces steam.

At this time, air bubbles are generated between the rings 4 and 5, but since these air bubbles escape from the upper and lower spaces between the rings, the thermal efficiency does not decrease as a result.

Further, in the lower part of the electrode, the volume of the support tube 8 is smaller, and the amount of water is correspondingly smaller, so that the thermal efficiency is extremely improved.

The steam generated as described above passes through the baffle plate 14 to have its dew drops removed and is ejected from the spout 15. The baffle plate 14 is supported as follows.

That is, a support plate 16 is provided on the upper side of the support cylinder 8, and the baffle plate 14 is suspended from this support plate 16.

Note that the reference numeral 17 in the figure is a safety valve.

As is clear from the above description, according to the device of this invention, bubbles generated between the electrodes can easily escape, and the thermal efficiency is improved accordingly.

In addition, since the required spacing is provided between the top and bottom of each ring, when the water level drops below a certain ring, it can be detected electrically.
It has also become possible to cut off electricity to the ring above the water level.

Furthermore, since the lower part of the electrode contains less water, the thermal efficiency is improved accordingly, steam can be generated in a single time period, and the amount of power consumed is also reduced.
