Abstract
A device for silverizing running water and an electrode therefor are formed so that the electrode has a curved guide provided on its one surface and a plurality of through-going openings located outside of the curved guide, to direct water to be silverized from inside of the curved guide to its outside and then through the openings.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a device for silverizing water and an electrode for a silverizing device.
Devices of the above mentioned general type are known in the art. The known silverizing device includes a plurality of positive electrodes and a plurality of negative electrodes alternatingly arranged in a housing provided with inlet and outlet for water. During running of water through the device, silver ions produced by positive electrodes saturate the running water. The electrodes are formed with different shapes and designs to provide a sufficient path of water for its saturation with a required quantity of positive ions of silver. There are further requirements to increase the path of water flowing near and through the electrodes so as to further increases the efficiency of the device for silverizing water.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a device for silverizing water and an electrode therefor, which insures a significant path of flow of water near the electrodes to provide efficient saturation of the electrodes with positive ions of silver.
In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a device for silverizing water and in an electrode in which one surface of the electrode is provided with a curved guide, and through-going openings are arranged outside of the curved guide, so that water flows inside the curved guide, is guided by the curved guide to outside of the guide, and then passes through the openings toward a next electrode.
The electrodes can be arranged over one another so that their curved guides extend in the same direction, or they extend in two opposite directions to further make longer the path of water and time of its contact with the electrodes.
The novel features of the present invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its manner of operation, will be best understood from the following description of preferred embodiments which is accompanied by the following drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a view showing a device for silverizing water as a whole;
FIG. 2 is a view showing an electrode for a silverizing device in accordance with one embodiment of the invention;
FIG. 3 is a view showing an electrode in accordance with another embodiment of the present invention; and
FIG. 4 is a view showing an electrode in accordance with still a further embodiment of the invention.
DESCRIPTION OF PREFERRED EMBODIMENTS
As shown in FIG. 1 , a device for silverizing running water has a housing 1 which is provided with an inlet 2 and an outlet 3 , and has an inner chamber 4. A plurality of electrodes 5 are arranged in the chamber 4 one above the other and have through-going openings.
When the device is attached to a water source for example a faucet by its inlet 2, and the electrodes 5 are supplied with respective current to provide alternatingly arranged positive electrodes and negative electrodes (of which the positive electrodes are silver-containing), water flows over and through the electrodes, is saturated by positive ions of silver produced by the positive electrodes, and issues through the outlet 2. The faucet and the current supply are not shown in the drawings for the sake of simplicity.
Each electrode in accordance with the present invention has a disc-shaped body 6 having two opposite surfaces. One of the surfaces of the body is provided with a curved guide 7 which in FIG. 2 is curved in a clockwise direction. Near its end which is located closer to a periphery of the body, a plurality of openings 8 are provided and extend through the body 6 of the electrode. These openings are located in a wedge-shaped surface portion which is limited by the curved guide 7. The curved guide is formed as a continuous uninterrupted member from its one end to its other end. As can be seen from FIG. 2, the through-going openings 8 can be inclined relative to the surfaces of the body of the electrode. The curved guide and the body can be formed as separate members connectable with one another or as a one-piece element.
When water supplied through the inlet 2 reaches the center of the first upper electrode, it is guided from inside of the curved guide 7 to outside of the curved guide, and then flows through the openings of the electrode downwardly to a lower electrode, then through the latter etc.
As can be seen from FIG. 3, the electrode shown in this figure has a curved guide 7' which extends, contrary to the curved guide if FIG. 2, in a counterclockwise direction, with through-going openings 8' also formed outside the curved guide 7'. In the device for silverzing water in accordance with the present invention, identical electrodes can be arranged one above the other, for example only the electrodes shown in FIG. 2 or only the electrodes shown in FIG. 1. In these case the projections of the curved guides 7 or 7' of all electrodes on a common horizontal plane will coincide with one another. On the other hand, the electrodes can be arranged so that the electrodes with clockwise and counterclockwise curved paths are arranged alternatingly with one another. In the latter case, the path of flow of water to be silverized is even longer and therefore the time of contact of water with the electrodes is also longer.
As shown in FIG. 2, the body of the electrodes can be formed as a flat disc. On the other hand, an additional peripheral wall 9 can extend upwardly from the same upper surface from which the curved guide 7 or 7' extend. While with the electrodes of FIG. 2 without the additional wall the wall of the housing 1 limits the inner chamber 4, with the electrodes of FIGS. 3 and 4 provided with the additional wall 9 the electrodes can just be directly installed on one another so that no housing wall is needed. The thusly formed electrodes can be connected by connecting means which are conventional and therefore and not shown in the drawings for the sake of simplicity. The wall portion which forms the curved guide 7' can be formed as a separate member, or on the other hand as a one-piece member with the additional wall 9.
The invention is not limited to the details shown since various modifications and structural changes are possible without departing in any way from the spirit of the present invention.
What is desired to be protected by Letters Patent is set forth in particular in the appended claims.
