Description

[Detailed description of the invention]

[0001]

The present invention relates to an ultrasonic filter provided with a sterilizing water purification filter made of fibrous activated carbon containing ceramics carrying at least one metal ion selected from silver, copper and zinc as a sterilizing water purification filter. It relates to a humidifier.

[0002]

2. Description of the Related Art Humidifiers are roughly classified into two types, a heater type and an ultrasonic type. Since the heater type generates steam, germs are not blown indoors,
Running costs are high and there is a problem in safety such as burns due to boiling water. The ultrasonic method sprays the water in the aquarium as fine mist-like water droplets, and there is a possibility that various bacteria that have propagated in the aquarium are blown into the room and cause symptoms such as a humidifier lung. For this reason, it is considered that the water tank is made of antibacterial plastics, and a sterilizing material is put in the water tank so that various bacteria do not propagate in the water tank.

[0003] For example, Japanese Utility Model Laid-Open No. 57-62813 discloses that a sterilizing filter in which silver, copper or an alloy thereof is adsorbed on fibers or activated carbon is installed in a water tank. It proposes that the sprayed water droplets diffuse through an antimicrobial filter. However, these methods have a poor sterilizing effect, cannot provide a very high effect, and are not effective in removing harmful ions such as chlorine. On the other hand, Japanese Utility Model Laid-Open No. 1-144724 proposes installing a chlorine filter. Thus, in the ultrasonic humidifier, it is desired to efficiently remove harmful ions such as bacteria and chlorine.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an ultrasonic humidifier capable of generating sterilized and purified spray safely and efficiently.

[0005]

A sterilizing filter used in an ultrasonic humidifier requires that a sterilizing agent does not elute into water. However, there are very few fungicides of such properties. It has long been known that metals such as silver, copper and zinc and their salts have antibacterial properties.The antibacterial properties of metals are such that metals are ionized in water in trace amounts to form colloidal carbonates and hydroxides. It is believed to show. However, since silver and copper metals and their alloys are extremely difficult to ionize even when immersed in water, silver, copper and their alloys are adsorbed on activated carbon and fibers as disclosed in Japanese Utility Model Application Laid-Open No. 57-62813. An antibacterial agent cannot have a strong antibacterial effect unless it contains a large amount of metal. On the other hand, these metal salts are often soluble in water,
It is difficult to use it for an ultrasonic humidifier because some of them show colors unique to metal salts.

[0006] Therefore, as a result of various investigations on the method of utilizing the bactericidal properties of metal ions such as silver, copper, and zinc, and the elimination of those metal ions into water, at least one of the methods selected from silver, copper, and zinc was selected. By installing an antibacterial filter made of fibrous activated carbon containing ceramics supporting metal ions, it was found that by installing an ultrasonic humidifier in the water tank, especially around the vibrator, it was possible to suppress the growth of various bacteria and purify the water. .

The ceramics in the present invention mean phosphates such as hydroxyapatite, tricalcium phosphate, zinc phosphate and zirconium phosphate, and silicates such as zeolite and silica glass. Zeolites and the like are particularly preferable as ceramics. Ceramics are added to an aqueous solution of a metal salt of silver, copper, and zinc, and the mixture is sufficiently stirred and filtered at room temperature or slightly heated to obtain a ceramic in which metal ions are supported by ion exchange or adsorption. The supported amount of metal ions is easily defined by the concentration and amount of the metal salt used, but the supported amount must be less than the saturated ion exchange amount or adsorption amount to the ceramic. Therefore, metal ions excessively contained in ceramics are sufficiently washed and removed with water. Since ceramics supporting metal ions by ion exchange are not affected by the counter anions of metal ions, elution of metal ions into water is preferred with almost no elution. The obtained metal ion-supporting ceramic is dried and pulverized before use.

[0008] However, depending on the type of metal salt used, metal ions may elute into water from the metal ion-supporting ceramics, albeit slightly. In order to prevent such elution of metal ions, it is preferable to fire the obtained metal ion-supporting ceramic at 800 ° C. or higher. By this firing operation, the ceramic shrinks and the bond between the metal ion and the ceramic is strengthened, so that the metal ion is not eluted into water, and the antibacterial property is maintained. 80
The metal ion-supporting ceramics fired at 0 ° C. or higher is used after being pulverized.

The fine powder of the metal ion-carrying ceramic obtained in this manner is mixed with fibrous activated carbon, and if necessary, heated and pressed in the presence of a generally used water-insoluble binder to a predetermined shape. Into a sterile water filter. The mixing ratio between the metal ion-supporting ceramic and the fibrous activated carbon is arbitrarily selected depending on the desired antibacterial property, or the mixing amount of the metal ion-supporting ceramic is at least 0.001% by weight based on the fibrous activated carbon. Need
Preferably, it is about 0.01 to 10%.

[Effect of the Invention] The sterilizing water purification filter according to the present invention is made of fibrous activated carbon containing ceramics carrying antibacterial metal ions, and thus exhibits strong antibacterial properties. Without elution,
In addition, it absorbs and removes harmful ions such as chlorine in water. Therefore, the ultrasonic humidifier provided with the humidifier does not cause germs and harmful ions to fly into the room.
