GENERAL DESCRIPTION OF THE PREFERRED EMBODIMENT: With reference to the figures 1-2, the constituents of this invention include a tank (10), inner ring electrode (20), outer ring electrode (30), the adjustable button for the up or down of the outer ring electrode, the water supply tube (60), water storage bottle (70) for the supply of water required inthe tank (10). It also keeps the water to the predetermined level. After the water level is determined, the electrode ring is immersed in the certain depth of water (20). Another electrode ring (30) is adjusted to be dipped in the water to some depth. It keeps a distance from the other electrode in space. That area is used for the heating of water. When the local part of water is heated and swell up to form the steam and foam. The water in that area is influenced by the electrodes (20) & (30).As for the frame (40), it is fixed upon the tank (10) to connect the power source and the installation of adjustable button (50). It also sets up a stabilizing rod (80) so that the two electrodes would not rotate to each other.

As shown in the drawing, the bottom (11) of the tank (10) indicates the concave groove for the sedimentation of dregs to be introduced out by a pipe so that the water in the tank (10) can be clean and can also keep the stabilization of the electrical current. In the fringe of the bottom (11) of the tank (10), installed was a ring shape platform (13) so that the ring of electrode can be placed thereon. A round hole is made in the vertical wall (14) of the tank (10) in supply of the water liquid through the pipe for the water supply.

Except for the unit (71), the water storage bottole is closely sealed. Hence, the water level of the tank (10) will be maintained on the upper brim of the round hole (15). In other words, when the water level of the tank (10) reduces, the air enters through the water liquid supply pipe (60) to the mouth of the bottle (71). Then the water raises to the inside of the water storage (70). The water storage bottole (70) shall immediately release the water so that the tank (10) can be replenished with water. The water level of the device can be maintained in the stable manner. Due to the stability of the water level, we can forecast that the depth in which the lower part of the electrode is immersed. Its stability can be maintained.

If the tank (10) is made up of the metal, then an insulated pad (16) between electrode ring (20) and the tank shall be installed. A wire is connected from the tank (10) to the ground for safety purpose. But in case that the tank (10), water supply pipe (60) and water storage bottle are not made up of metal. The material is electrically nonconductive, then the "ground wire connection" will otherwise be installed.

Electrode ring (20) is a slanting conical body which is made up of non-oxidable metal as shown in the Drawings 1-2. Its lower part has opening (21). The circumference of the opening (21) shows many apertures (22), which can make the flows of water more easily in the tank (10).

The upper part of electrode ring (20) is in the shape of a platform (23). In the platform, there installs two concave holes (24.25). The concave hole (24) is in the middle for the insertion of the bottom of the adjustable button so that the rotation shaft of the adjustable button (50) can be firmly fixed in the position.

The concave hole (25) is provided for the insertion of the bottom part of the stabilization rod so that its lower part (80) can be stabilized. Also, in the platform 23, there install many ventilation holes (26) to make the inner and outside parts having the stable pressures.

The electrode ring (30) is also a slanting conical body. Its slanting degree is same as that of electrode ring (20). In other words, the functional positions of the electrode rings (20) (30) are in parallel. In the upper part of the electrode ring (30), there installs a platform (31). In the middle of the platform (41), a block (31) is fixed. At the middle of the platform (41), there is a fixation of a block (32).

In the middle of the block (32), there are threadings which are used for the coordination with the screw rod (51) of the adjustable button (50) to make the whole electrode ring (30) to be adjustable in up or down position. In the platform (31), another hole is made (33) for the passing through of the stabilizing rod (80). But because the stabilizing rod's upper part is fixed at the frame (20) and its lower part is inserted into the concave hole (25) of the electrode ring (20), the stabilizing rod (80) will make the electrode ring (30) to be incapable to rotate so that it can only move up and down. In the platform (31), there installs another hole (34) for the passage of the electrically conductive part (27) of the electrode ring (20). Also, in the platform (31) some holes are made to provide the passing of the steam vapor.Certainly, the holes (34,33) can be provided for the passage of the vapor steam.

From the first drawing, the gap between the electrodes (20, 30) is the main place for the generation of the steam vapor. The place where the two electrodes are immersed in water is the heating whereabout. Its depth is 30mm-20 mm with good effect. When the water is heated up, it becomes the foaming and vapor which swell up in the space between the two electrodes (20, 30) forit receives the heating effect. On that account, we know that the gap between the two electrodes (20, 30) must be long enough to allow the part of electrodes to be immersed in the water where the water can be heated up into steam vapor. That position is very important part of this invention.

The frame (40) is installed on the upper part of the tank (10) like a wheel shape inluding outer ring (41), four legs (42) and inner rings (43). In the lower part of the outer ring (41), some insertion legs are installed (44) to be inserted firmly into the vertical walls (14) of the tank (10) so as to make the tank frame secured. Three of four legs shall respectively be installed with electrode rings (20,30), screws (28,36) and stabilizing rod (80). The electrically conductive screw (28) is connected to the electrode (30) with the ring shaped spring board (37) as conductive part. The stabilizing rod (80) shall pass through the hole (33) and reaches the concave hole (25). The above ring shaped spring board (37) is used to coordinate with the up and down movement of the electrode ring (30) to be condusive to the electrical current effectively.

The adjustable button (50) is installed at the middle of the inner ring (43). The structure of the adjustable ring (50) includes the long screw rod (51) and adjustable button (52) with a washer (53) to be fixed on the long screw rod (51) so as to make the whole adjustable button which can be move upward.

The threading of the above long screw rod is in coincidence with the threading of the block (32). Because the movement of adjustable button (52) makes the rotation of the long screw rod (51), then the block (32) moves up and down.

When the block moves up or down, the electrode ring (30) moves up or down. Thus the gap between the two electrodes (20,30) and the depth of the immersion of the electrode rings in the water have been changed.

The purpose for such change is to (1) accomodate the device to the different kinds of water qualities so as to regulate the consumption of electricity. (2) to adjust the volume of steam vapor.

In summary, the characteristics of this invention is to use the two electrodes (20, 30) and their gap as well as the depth of immersion of the electrodes in the water and the their length above water to constitute a high efficient, practical, and fast steam generator.

By the advantages of these characteristics, you may use the designing in the Drawing 3-4 to generate more steam vapor within certain scope. Its difference with the designing of Drawings 1-2 is to change the form of the electrode rings so that more and smaller positions are formed. In other words, the installation of more gaps for the generation of steam vapor. Now we discuss it briefly.

A tank (10) is installed. In it, the bottom (11) of a concave tank is equipped with a pipe to introduce the water out. Some fixation blocks (13) are installed to place the electrode plate (20) in the vertical wall (14). In the wall, hole is made (15), in coordination with the water supply pipe (60) to make usre of water level. On the fixation block (13), the convex point (16) is installed to stabilize the lectrode plate (20). In the vertical wall (14), there in stalls concave tank (17) to place the electrically condusive plate (24).

In the middle of electrode plate (20), there installs a round hole (21) to pass through the long screw rod (51). On the electrode plate (20), some ring tanks (22) are installed. The lower parts of these ring tanks are inserted in the water. The upper part are left above the water.

The middle of the electrode plate (30) is equipped with block (31). By the use of threading (32) and long screw rod (51), it coordinate with their functions to make the electrode plate to move up or down. On the electrode plate (30), there install some ring tanks (33). Their lower parts are inserted in the water. In other words, some ring tanks (22,33) are coordinated together to produce the steam vapor. The outer ring of the electrode plate is lighter. In the plate, there are some apertures (34) to vent off the upward steam vapor.

The frame (40) is also installed with some insertion legs to make the frame to be stable.

The frame will firmly inserted into tank (10).

Some branch legs are installed (42) to equip the condusive screws (23, 35) of the two electrode plates. By the use of the conductive plate (24) and ring shaped spring board (36), the two conductive screws (23, 35) are connected to the two electrode plates (20,30).

The adjustable button (50) is equipped with long screw rod (51), adjustable button (52), washer (53) to be coordinated with the blcok (31) to make the electrode plates (30) up or down.
