INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION C FIELD OF THE INVENTION The present invention relates to an air purifying apparatus and an air conditioner or refrigerator using the air purifying apparatus. C. Prior Art 3 [Invention] In the air purifying apparatus disclosed in Patent Document 1, the light from the light-emitting diode is irradiated onto the substrate on which the photocatalyst substance is disposed, 10 to decompose and purify the air. Not pure. Further, as disclosed in Patent Document 2, a photocatalyst and a light source are used to decompose an odor adsorbed on the adsorbent. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. A photocatalyst that utilizes irradiation with light to increase activity is used, and in the absence of light, it has no effect at all. When the apparatus having the air purifying device is stopped, the electric power cannot be supplied to the air purifying device, and the light source cannot be activated without activation of the photocatalyst, so that the odor decomposition effect or the antibacterial effect of the air purifying device cannot be exhibited. Further, when the light is irradiated on the photocatalyst, when the light of the low-wavelength ultraviolet region 200909010 is irradiated, the resin constituting the air purifying device is deteriorated due to the combination of the decomposing molecules in the ultraviolet region, and therefore it is necessary to take countermeasures. In addition, in the ultraviolet light, a light source of a low-wavelength sterilization line is emitted, and at the same time, ozone which affects the human body is emitted, and countermeasures for removing ozone 5 are also required. Even with high-wavelength light, the energy is too small to obtain sufficient effects. SUMMARY OF THE INVENTION An object of the present invention is to provide an air purifying device which can solve the above-mentioned conventional problems and which has an antibacterial action when the device is operated or stopped, does not deteriorate the resin, and is safe and inexpensive for the human body. And an air conditioner or refrigerator using the air purifying device. [Means for Solving the Problems] In order to solve the above-mentioned problems, the air purifying apparatus of the present invention includes: a filter member having at least silver formed on the surface; and light having a wavelength of more than 400 nm and 520 nm or less The light source of the surface 15 of the filter and member. Thereby, even if the air purifying device is stopped and the light source is not irradiated with light, the filter member can be made antibacterial by the silver placed on the surface. Further, when the air purifying device is operated, i.e., light from a light source is irradiated to the filter member, it exhibits higher antibacterial properties. Further, since the wavelength of light is limited, 20 can maintain the antibacterial property of silver in a high state, and deterioration of the resin used in the air purifying device can be suppressed. Moreover, since the light of this wavelength does not cause ozone, it is safe for the human body. Therefore, the effect of the above invention is to provide an inexpensive air purifying device. [Effects of the Invention] 200909010 The air purifying device of the present invention also has an antibacterial action at the time of stopping, and exhibits a higher antibacterial action during the charging operation, does not deteriorate the resin, is safe for the human body, and can purify the air inexpensively. . The air conditioner of the present invention can be used in a manner that further enhances the antibacterial property of the air purifying device, and is hygienic. The refrigerator of the present invention can be used in a manner that can improve the performance of the air purifying device during the refrigerating operation, and is hygienic. [Capital method j [Best form of the present invention (4)] The first invention is characterized in that a filter element having at least silver on the surface thereof is provided, and light having a wavelength of more than 400 nm and 520 nm or less can be irradiated to the foregoing. The light source on the surface of the transition member can further enhance the antibacterial activity of silver, and can also exert an antibacterial effect when light is not irradiated. Moreover, since the resin is not deteriorated due to the limitation of the wavelength of light, it is possible to provide an air purifying device having an antibacterial ability which is inexpensive and safe for the human body. According to the second aspect of the invention, the silver is formed into an acid-filled silver, and since the acid-impaired silver is reported as a non-dissolving type, the filter member can be washed with water and is hygienic. According to the third aspect of the invention, the illuminance of at least a part of the surface of the filter member is set to be more than 10 lux, whereby a sufficient antibacterial effect can be obtained. According to a fourth aspect of the invention, the light source is formed as a light-emitting diode, whereby an inexpensive air purifying device can be provided. According to a fifth aspect of the invention, the air purifying device according to the first aspect of the invention is installed in an air conditioner, and can be used in a manner that improves the antibacterial performance of the air purifying device, and is hygienic. In the sixth aspect of the invention, the air purifying device according to the first aspect of the invention is installed in a refrigerator, and can be used in a manner that improves the antibacterial performance of the air purifying device during the refrigerating operation, and is hygienic. Embodiments of the present invention will be described below with reference to the drawings. Further, the present invention is not limited to the embodiment. (Embodiment 1) Fig. 1 is a cross-sectional view showing an air purifying device according to a first embodiment of the present invention. As shown in the figure, the air purifying device 5 has a casing 1 on which the inner wall 10 of the casing i is provided with a filter member 2, and a plurality of light sources 3 are disposed at positions where the light can be irradiated on the filter member 2. Between the filter member 2 and the light source 3, a vent hole 4 for venting or discharging air from the outside of the air cleaning device 5 is formed. The light source 3 is a light emitting diode (hereinafter referred to as lED). Further, light having a wavelength greater than 400 nm and 520 nm or less can be irradiated. 15 The filter member 2 is made of a polyester resin as a base material, and a zirconium phosphate having a silver blending amount of 3 wt% is used as an acrylic binder, and is applied to the surface of the substrate at 2_2. Further, as the carrier of silver, a carrier such as zeolite, silicone, glass, calcium phosphate, citrate or titanium oxide may be used. In particular, when silver zirconium phosphate is used, since silver is not easily eluted in water, it is the best choice when it is decided to wash the filter member 2 with water. Further, the filter member 2 is not only coated on the surface of the substrate by using silver strontium phosphate as a binder, but also molded by stirring a polyester resin having a phosphoric acid wrong silver. Further, in the embodiment of the present invention, the filter member 2 is formed in a thin plate shape, but 200909010 is not limited to the shape, and may be formed into a honeycomb shape, a folded shape, a non-woven fabric or the like. (Experimental Example 1) First, in Comparative Example 1, a thin plate-shaped filter member containing no silver was prepared as a 5 fake product. The bacterial solution of S. aureus was spray-coated on the filter member of the silver-free fake product of the air purifying device 5 of Fig. 1, and then light-shielded for 3 hours. Then, the counterfeit filter member was removed and washed with physiological saline, and the number of bacteria in the eluate was set to be about 1 〇xl 〇 6 CFU/cc. The measurement of the number of bacteria was carried out by subjecting a standard cold weather medium to a plate dilution, and after 48 hours of culture at 35 ° C, a method of calculating colonies in the form of cold days was carried out. Then, the bacterial solution of S. aureus was spray-coated on the thin plate-shaped filter member 2 of the polyester resin in the same manner as the spray state set in Comparative Example 1, and 2% by weight of the polyester resin was mixed therein. The silver mixed amount of 3 wt% contains 15 silver zirconium phosphate. Then, the light source 3 was not caused to emit light, and the air purifying device 5 was allowed to stand for 3 hours. Thereafter, the filter member 2 was removed, and washed out with physiological saline. The number of bacteria in the eluate was 1.0 x 10 〇 3 CFU/cc, which was confirmed to be more antibacterial than Comparative Example 1. Further, the same test is performed using the LEDs of various wavelengths in the light source 3. The irradiation time was set to 3 hours, and the external light was shielded from light. The average illumination intensity on the filter member was adjusted to 150 LUX. (Table 1) shows the peak wavelength of the center of the LED used in the experiment and the number of bacteria after the culture of the filter member washed out after the irradiation. [Table 1] 9 200909010 It is clear from the results of (Table 1) that if the center of the test 丨~6 has a central bee wavelength of 520· or less, and the center peak wavelength exceeds 520 nm, the test is performed. 8 comparison, the number of bacteria after cultivation is greatly reduced. Here, the light energy of the wavelength of 5 center peak wavelengths of 53 Gnm or more is insufficient, so that sufficient antibacterial effect cannot be obtained, and sufficient light energy can be obtained by irradiating light having a center peak wavelength of 52 Å or less, and not only silver can be improved. The antibacterial activity can obtain a larger antibacterial effect. Further, from Tests 1 to 4, the acrylic binder was mixed with the silver-containing phosphoric acid 10 zirconium and applied to the surface of the filter member, and the filter member 2 was used to continuously operate for 2 hours. In the test crucible and the test 2, the filter member 2 was deteriorated by the ultraviolet rays destroying the molecular structure of the resin, and the film applied to the surface of the filter member was peeled off. In Tests 3 and 4, the resin did not deteriorate due to the wavelength of the non-ultraviolet light, and the film did not peel off. 15 (Experimental Example 2) Next, in the air purifying device 5 similar to the test 3 of Experimental Example 1, the illuminance of the filter member 2 can be changed by adjusting the distance between the light source 3 and the filter member 2. The change of the bacteria applied to the filter member was ascertained in the same manner as in Experimental Example 1. (Second table) is the number of bacteria after the illuminance of the filter member 2 and the bacteria washed out from the filter member 2 after the irradiation. The test conditions were the same as in Experimental Example 1. [Table 2] It is apparent from (Table 2) that if the illuminance of the test 13 to 18 is above 10 OLux, and the illuminance of the test Π and 12 is less than 90 Lux, the number of bacteria after the culture of 200909010 becomes Quite a few, with excellent antibacterial effect. On the contrary, the illuminance is below 90 Lux, and since there is not enough light energy, sufficient antibacterial effect cannot be obtained. By using light having an illuminance of 10 or more ohms, sufficient light energy can be obtained, which not only improves the antibacterial activity of silver, but also obtains a greater antibacterial effect than the fifth. (Embodiment 2) FIG. 2 is a cross-sectional view showing an indoor unit of an air conditioner according to a second embodiment of the present invention. The air conditioner 15 as shown in the figure is an air conditioner which can be a cooler, that is, a so-called air conditioner. The air conditioner 15 has a casing 10, a heat exchanger 11, a crossflow fan 12, and a wind direction plate 13, and has the air cleaning device 5 used in the first embodiment. Further, the above respective devices or members are disposed inside the air conditioner 15. First, in Comparative Example 2, a thin plate-shaped filter member containing no silver was prepared as a 15 fake product. In the air purifying device 14, a bacterial solution of Staphylococcus aureus is spray-coated on a filter member containing no silver fake, and then light-shielded for 3 hours, and then the dummy filter member is removed to physiological saline. The water was washed out, and the number of bacteria in the eluate was set to be approximately 1 · 〇 X 106 CFU / cc of the bacterial liquid spray state. The number of bacteria was measured by plate dilution in a standard cold day medium, and after 20 hours of incubation at 35 ° C, the method of calculating the colony of the cold day culture medium was carried out. Further, the air conditioner 15 was tested in a non-operating state. (Experimental Example 3) Experimental Example 3 was applied to an air purifying device 5 using a silver compounding amount of 3 wt% 11 200909010 = phosphoric acid silver as an acrylic binder, and coating it in a thin plate shape of a polyester resin at 2 g/m 2 . On the transition member, after the spray coating and the same amount of the same amount of the staphylococcus aureus as in Comparative Example 2, the entire air purifying device 5 was shielded from light, and after standing for 3 hours, the filter member 2 was removed and washed with physiological saline. 5 out. The number of bacteria in the eluate was 攸 攸 / / ", and it was confirmed that the antibacterial property was obtained. Further, the air conditioner 15 was tested in a non-operating state. (Experimental Example 4) Next, Experimental Example 4 was in the light source 3. The test was carried out using a 1 〇 LEDit with a center peak wavelength of 45 〇 11 claws. The air purifying device 5, the filter member (10) was prepared by using silver cerium phosphate in an amount of 3 wt% of silver as an acrylic binder, and coated at 2 g/m 2 . The thin resin of the ester resin was sprayed onto the filter member 2 by the same amount of the same amount of the bacterial solution of S. aureus as in Comparative Example 2. The light of the above wavelength was irradiated against the filter member 2 for 3 hours, and the filtration was removed. The member was washed out in a row with physiological saline. In addition, the entire air conditioner 15 was shielded from light by external light, and the average illuminance on the filter member 2 was adjusted to 150 LUX. The number of bacteria after the culture of the bacteria washed out by the filter member 2 was 4.0×10′, and it was confirmed that the bacteria had an antibacterial effect.

The number of bacteria after the culture of the filter member 2 washed out after 3 hours of self-irradiation was 1 〇 X 12 200909010 ίο. Here, after the air-conditioning operation, the inside of the air conditioner 15 becomes wet, and since it is rich in moisture required for the photocatalytic reactivity of silver at the time of irradiation, it is possible to improve the activity. Further, in the air conditioner 15 of Experimental Example 4, the cold air was operated for one hour and then stopped, and the light source 3 was tested using an LED having a center peak wavelength of 450 nm. The irradiation time was 3 hours, and the entire air conditioner 15 was shielded from light from the outside to the air purifying device 5. The average illuminance on the filter member 2 was adjusted to 150 LUX. Filtration after 3 hours from the irradiation 10 The number of bacteria after the culture of the bacteria washed out of the member 2 was 1.2 x 10. Here, after the cooling operation, the inside of the air conditioner 15 becomes high temperature, and the photocatalytic reactivity of silver at the time of light irradiation should be improved. (Embodiment 3) Fig. 3 is a cross-sectional view showing an air purifying device 15 according to a third embodiment of the present invention. The air purifying device 5 as shown in the figure has a housing 1. The inner wall of one of the casings 1 is provided with a filter member 2, and a plurality of light sources 3 are mounted on the inner wall of the other face. A vent hole 4 for venting or discharging air from the outside of the air cleaning device 5 is formed between the filter member 2 and the light source 3. Further, the air purifying device 5 has a supply unit 20 that supplies water to the vent hole 4 through the casing 1. The filter member 2 was a polyester resin coated with 2 wt% of silver zirconium silver as an acrylic binder and 2 g/m2. Further, the air purifying device 5 is mounted on the top of the inside of the refrigerating compartment 102 of the refrigerator 1 (see Fig. 4). First, in Comparative Example 3, a thin plate-shaped filter member containing no silver was prepared as a 13 200909010 fake. In the air purifying device 5, the bacteria liquid of the Pluto Station and the S. sphaeroides are sprayed on the transition member which is not impregnated with silver, and then placed in a light-shielded place for 3 hours, and then the shouting member is removed. The finances are washed out, and the number of bacteria in the eluate is set to be about 1.0xl06CFU / cr々, and the spray state of the liquid i. The measurement system of the number of bacteria, the standard cold weather base was used for plate dilution, and after 48 small _ riding under the pit, the method of calculating the colony of the cold day culture was carried out. In addition, the test was carried out in a state where the refrigerator was not operating. (Experimental Example 5) As Experimental Example 5 'In the air purifying device 5, the filter member city (4) Π) used a silver mixed amount of 3 wt% of silver citrate as a (tetra) acid-based binder, and clothed at 2 g/m. The thin plate of lyophile. Then, after the spray coating and the same amount of the same amount of the bacterium of the yellow staphylococcus of Comparative Example 3 were applied, the air purifying device 5 was shielded from light and left for 3 hours. Thereafter, the filter member 2 is removed and washed out with physiological saline. The number of bacteria in the eluate was i〇x1〇3cfu 15 /CG, and it was confirmed that it had antibacterial properties. Further, the test was carried out under the condition that the ice liHK) was not in operation. (Experimental Example 6) Next, in Experimental Example 6, the light source 3 was touched using an LED having a center peak wavelength of 47 fine. In the air net area, 5 towels were used, and _ survey 2 was used. 20 silver mixed amount of 3 wt% of zirconium phosphate was used as the acrylic acid binder, and 2 Å was applied to the thin plate of the poly S resin. Then, the same amount of the same amount of the bacterium of the bacterium of the genus Staphylococcus aureus was applied to the transition member 2, and the light was irradiated with the light source 3 for 3 hours. Then, the filter member was removed and washed out with physiological saline. In addition, in the test, the external air is not allowed to enter, and the air purifying device 200909010 is set to 5 to shield the light. Further, the average illuminance on the filter member was adjusted to 150 LUX. The number of bacteria after the culture of the bacteria washed out from the filter member 2 was 3.9 x 10. When compared with Experimental Example 5, it was confirmed by light irradiation that the antibacterial property was improved upward. 5 (Experimental Example 7) Next, in Experimental Example 7, the refrigerator 100 was refrigerated for 1 hour, and after stopping, the light source 3 of the air purifying device 5 was tested using an LED having a center peak wavelength of 470 nm. Moreover, the atomized ice making water is supplied from the supply unit 20. The irradiation time was 3 hours, and the air purifying device was set to 5 to prevent light from entering from outside. The average illuminance on the filter member was adjusted to 150 LUX. The number of bacteria after the culture of the bacteria washed out by the filter member 2 after the irradiation for 3 hours was 0.9 x 10, and when compared with the experimental example 6, it was confirmed that the antibacterial performance was improved upward. In Experimental Example 7, the inside of the air purifying device 5 became moist, and since it was necessary to absorb the moisture required for the photocatalytic reaction of silver at the time of irradiation, it should be possible to enhance the activity. [Industrial Applicability] As described above, in the air purifying apparatus of the present invention, since the antibacterial activity of the silver-containing filter member is increased by the irradiation light, the use 20 is not limited to the air purifying device.
