MULTI-FUNCTIONAL SILVER HUMIDIFIER CAPABLE OF USING DISTILLED WATER AND SILVER SOLUTION SELECTIVELY AND HUMIDIFICATION METHOD THEREOF Technical Field The present invention relates to a multi-functional silver humidifier, more particularly to a multi-functional silver humidifier capable of producing silver solution using distilled water obtained from general water, or using selectively the produced distilled water or silver solution, and humidification method thereof Background Art Generally, in the winter when the rainfall is very insufficient and the humidity greatly decreases due to freezing of moisture by cold, the surrounding air is very dry, moreover the indoor air is exceedingly dry by the heat evolved from a heater used in home or office. If the dry indoor is lastly maintained, such a condition is detrimental to human health.

Accordingly, to get rid of such a problem, a humidifier for artificially creating the moisture in the dry indoor air is used. The humidifier can be classified into two large groups based on how to generate the moisture. One is a heating type humidifier in which the water in a water reservoir is heated up to the predetermined temperature, thereby the vapor created by the heating is sprayed naturally into the air. The other is an ultrasonic wave type humidifier in which the water in a water reservoir is minute by oscillation of ultrasonic wave, thereby the minute water particles are sprayed into the air.

In a conventional humidifier, considering that it is very harmful to a human body, especially a patient or infant when bacteria in the water are not sterilized and vaporized particles are sprayed into the indoor, the humidifier may be provided with a sterilizing chamber having a heater. Also a heater may be installed in a humidifying chamber in order to enhance the vaporization efficiency according to oscillation of an oscillator by means of heating the water and relaxing water molecules. However, in such a case, the oscillator is heated over a Curie point of 140-150°C by humidification of heated water and

its magnetic properties are changed, thus its efficiency and lifetime are greatly deteriorated.

Also, an additional device should be purchased to obtain the distilled water in the prior art. Also, there was inconvenience to put the distilled water into the humidifier for the production of the silver solution.
