Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a device for silverizing water. 
     Devices of the above mentioned general type are known. The known devices include silver electrodes and a water passage formed so that during activation of the electrodes the water is saturated with silver ions which have a string bactericidal action. Thus the water is cleaned of bacteria, viruses,etc. and can be used for drinking. The device can be installed even on a faucet of tap water. The known devices however possess some disadvantages in the sense of providing an automatic operation and insuring a stable and desired degree of silver ions saturation. 
     SUMMARY OF THE INVENTION 
     Accordingly it is an object of the present invention to provide a device for silverizing water which operates automatically and provides a desired silver ions saturation of water. 
     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 which has a plurality of electrodes supplied with electric current, water inlet and outlet means arranged to direct water alternatingly past the electrodes, and means for maintaining a desired water temperature in the device, and a silver concentration. 
     It is another feature of the invention to provide a device in which first portions of water are drained without being silverized. 
     It is a further feature of the invention to provide a cup-shaped device which utilized a float-like activator and can also be provided with the temperature stabilizing or maintaining means. 
     The novel features of the present invention are set forth in the appended claims. The invention itself however both as to its construction and its method of operation will be best understood from the following description of preferred embodiment which is accompanied by the following drawings.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     The device in accordance with a first embodiment shown in FIGS. 1 and 2 has a pressure relay 2 operatively connected with a magnetic valve 3 cooperating with the plunger 4 for acting on an opening for draining 5 and a main passage 6. The latter leads to a filter 7. A cooling medium condensor 8 is connected through a cooling medium filter 9 with a compressor 10 having a cooling medium supply valve 11. A passage 12 is a starting part of an outer helical passage in the wall 31 for the cooling medium. The filter 7 is connected with a central helical passage 13 for water. An inner helical passage 14 is provided for accommodating a heating medium or wire. 
     A control panel 16 has a button polarity reversal 24 for activating the silverizing process, and a button 25 for acting on a magnetic valve 15 to allow passage of water without silverizing. The counter 17 counts the amount of used water by a user and after a certain amount has been used activates a yellow lamp indicator 18 to indicate that the device must be cleaned, or more particularly its electrodes must be cleaned. 
     The green lamp indicator signals that a standard dosage of silver saturates the water, and a user can drink this water. A time relays 20 operates the magnetic valve 3 to allow a desired amount of first water to be drained through the opening 5. A thermostat 21 determines the temperature of water and activates the heating medium 14 to heat the water. A thermostat 22 determines the temperature of water and activates the cooling medium system, as will be explained hereinbelow. 
     A magnetic valve 23 operates for supplying the water to the electrodes 32. The electrodes can be formed as alternatingly polarized silver electrodes connected with electrical conductors 30. A spring 26 cooperates with the plunger 3 for closing and opening the latter, as will also be explained hereinabove. 
     A helical passage or pipe 13 of silverized water ends in a pipe 27 which connects the helical passage with an opening 35 of a lower electrode 34, and then water passes the the neighboring electrode 36 with the guide 37 and a plurality of openings 38. As shown in FIG.3, the flow of water can be in an opposite direction, namely downwardly. 
     The device has a housing 28 and an electrical push button relay or on-off switch 29. 
     When water is supplied into the device as identified with reference numeral 1 the pressure relay senses the water pressure and activates the time relay 20. The latter during 1-2 sec. allows the spring 26 to hold the plunger 4 so that the draining opening 5 is open and first water is drained. Then after the above time elapses the magnetic valve displaces the plunger so that the draining opening is closed and a supply opening 6 is opened. The water runs into the filter 7 in which it is mechanically (or in other ways) filtered. The filtered water then flows into the central spiral passage of the wall 31 which surrounds the electrodes 32, and then through a magnetic valve 23 which is open runs into schematically shown space between the electrodes 32. After being saturated with silver, the water leaves the devices through an outlet pipe 33. 
     If the water is too warm, the thermostat 22 activates the compressor 10 which through the cooling medium (freon) filter 9 and condensor 8 supplies the cooling medium through the passage 12 into the outer cooling medium passage of the wall 31. If however the water is too cold, the heating medium is supplied into the inner heating medium passage of the wall from a not shown source, or a heating wire in this passage can be heated electrically. 
     The device is started by pressing the electrical relay--29. By pressing the button 25 of non-silverized water the magnetic valve 15 is activated and provides a passage of the water without silverizing. In contrast, by pressing the button 24 the water is subjected to silverizing. The counter 17 counts the quantity of glasses of water produced by the device and after for example 500 glasses activates a yellow lamp indicator 18 which signals that the electrode must be cleaned. The green lamp indicator indicates that the standard dosage of silver is present in water and a user can drink the water. 
     The electrodes can include a plurality of pairs each having an electrode 34 with a central opening 35 and a neighboring electrode 36 with a guiding projection 37 and a plurality of openings 38. 
     The device shown in FIG. 4 is a cup to be used during travels, trip, and also in other situations. It has a housing 7, a cover 1 which is pivotable on a hinge 11 between a closed and an open position, a guide 9 formed as a pipe with perforated walls can be plastic, electrodes 45 and 46 located in the bottom region of the guide, and a float 4 moveable in the guide and having a height which corresponds to the height of the electrodes. Electrical conductors 3 extend inside a handle 8 and are connected with a switch 2 and a battery 6 with a time relay 5. A green lamp indicator 10 signals that a user can drink the water. 
     The housing is filled with water and the float 9 raises and switches on the switch 2 which activates through the time relay the battery 6. The latter supplies the electrodes and the electrodes during the time designated by the relay saturate the water with silver ions. The user opens the cover and drinks the water. When all water has been used, the float descends and occupies a space between the electrodes so that no current can pass between the electrodes when there is no water in the device. The float is composed of an electrically isolating material. 
     It should be emphasized that in the second embodiment of the invention shown in FIG.4, the device can also be provided with the same heating and cooling means which are alternatingly activated as in the first embodiment. Also the means for signalling a need of cleaning can be provided in the second embodiment as well. 
     The invention is not limited to the details shown since various modification 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.
