Mode of Poverty: J. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. Further, the present invention is not limited to the embodiment. (Embodiment 1) Fig. 1 is a cross-sectional structural view of a washing machine in accordance with a first embodiment of the present invention. Fig. 2 is a perspective view of an electrolytic cell of a washing machine, and Fig. 3 is a plan view of a washing machine. As shown in Fig. 1, the "1520 .... eight W" of the washing machine is disposed in the outer tub 2 and is freely rotatable in the inner tub 3, and the outer tub 2 and the inner tub 3 form the washing tub 4. The light irradiation device 5 is disposed in the vicinity of the peripheral edge portion of the opening slightly provided on the front side of the outer groove 2. One end of the drainage path 6 is connected to the lower portion of the outer tank 2, and the drain valve 6 is connected to the drain valve 7, so that the washing water in the washing tank 4 can be discharged. The water supply to the washing tank 4 opens the water supply valve 8 of the water supply path 9, and is supplied to the washing tank 4 through the electrolytic cell 10. The inner groove 3 is formed in a cylindrical shape with a bottom portion, and a plurality of water-passing holes 3a communicating with the outer groove 形成 are formed on the circumferential surface thereof, and a plurality of water-passing holes 3a are provided at a plurality of positions on the inner circumferential surface. The center of rotation of the inner groove 3 is provided with a rotation b in a direction slightly inclined, and the axial direction of the inner groove 3 is inclined upward from the back side toward the front side with 200902790. The rotating shaft 3b is coupled to the motor 12 attached to the back side of the outer tub 2, and the driving inner tub 3 is rotated in the normal rotation direction and the reverse rotation direction. Further, the lid 13 can cover the opening portion 2a of the upward inclined surface provided on the front side of the outer tub 2 so as to be freely switchable. Moreover, by opening the lid 13, the laundry can be taken in the inner tank 3. Since the cover 13 is disposed on the upwardly inclined surface, the washing and discharging can be performed without using the waist. Therefore, the washing machine of such a configuration can improve the problem of poor workability of the washing machine in which the laundry is handled by the opening in the lateral direction or the upward direction. Further, the control device 15 operates the drain valve 7, the water supply valve 8, and the motor 1210. As shown in Fig. 2, the electrolytic cell 10 for supplying the photo-activated antibacterial material is provided with two plate-shaped silver electrodes 32 in the casing 31, and a water flow population 33 is provided at one end of the long-hand direction. - The end is provided with a water outlet % and is connected to the 15 20 water supply path 9. The inside of the casing is - along the water flowing from the inflow to the heart, and the 2# plate electrode is arranged in the side, that is, the ions are supplied with light to stimulate the silver of the antibacterial material. Further, a voltage connection terminal 35 is applied to the electrode 32. In the state where water is present in the casing 31, when a predetermined voltage is applied to the electrode η, metal ions constituting the metal of the electrode 32 are eluted from the anode side of the electrode 32: in the electrolytic cell 10, by application of voltage To choose the bath of metal ions, non-dissolving. Second, by controlling the current or voltage application time, the metal ion can be controlled: 1. When the current flows for a long time in the electrolysis (4), the electrode 32 of the anode is consumed, and the electrode on the cathode side is in the water 9 200902790. The impurity is fixed on the scale. Also, the sulfide is low, due to 5 operation. The chloride of the constituent metal of the electrode 32 is generated on the surface of the electrode 32. Since the performance of the electrolytic cell 1 is lowered by the vaporization and the sulfide, the polarity of the electrode 32 is reversed to cause an electro-dynamic circuit (not shown). Next, the operation of the washing machine of the embodiment of the present invention will be described. The cover 13 is opened. When the washing material 14 and the lotion are put into the inner tank 3 to start the washing machine, the water of the air volume is injected into the outer tank 2 by the water supply path 9, and the material 12 is driven to rotate the inner tank 3 to start the washing step. By the rotation of the inner tank 3, the sump 14 accommodated in the inner tank 3 repeatedly lifts the baffle 11 provided on the inner circumferential surface of the inner tank 3 in the rotational direction, and is raised by the appropriate height. The stirring action of the falling temperature is performed by the action of the knocking. When the washing is performed for a predetermined period of time, the dirty washing liquid is discharged from the drain path S. Then, the dewatering operation is performed by rotating the inner tank 3 at a high speed. The washing ship contained in the washing material 14 is dehydrated, and then the water to which the silver ion water generated by the electrolytic cell is added is injected into the outer tank 2 by the water supply path 9, and the washing process is performed. The sulcus 14 contained in the inner tank 3 is also repeatedly rotated by the inner tank 3. The rinsing is performed by the hoisting and lifting of the damper 11. When the rinsing is performed for a predetermined period of time, the washing liquid is discharged by the draining path 6. And the knee is washed by the dehydrating action of rotating the inner tank 3 at a high speed. The knee-washing liquid contained in the substance 14 is dehydrated, and the rinsing is completed; the water-removing step is performed. In the step of consuming the money, the light is irradiated to the washing material 14 and the washing liquid to which the metal ions are added by the light irradiation device 5. When the cover 13 is made of a light-transmitting material, in addition to the light of the light returning device 5 200902790, the indoor light can also receive the light of the indoor lighting, which can improve the sterilization effect of the light. The groove 4 is formed to have a tilt angle of the front lift, and further, when the cover 13 is formed of a light transmissive material, in addition to the light 5 of the light irradiation device, the light of the indoor illumination can be easily received, and the light can be improved. The sterilization effect is because the inclined cover 13 which makes the washing tank 4 to be inclined at an oblique angle can absorb a large amount of diffused light in the same area as compared with the conventionally disposed cover provided in the horizontal direction. In the embodiment, the rotation center of the inner groove 3 is 1〇 The rotation axis 3b in the oblique direction is substantially inclined, and the axial direction of the inner groove 3 is inclined upward from the back side toward the front side. However, the rotation center of the inner groove 3 may be a rotation axis of a substantially horizontal direction, and the inner groove 3 may be provided. The axial direction is arranged in a substantially horizontal direction. Alternatively, the center of rotation of the inner groove 3 may be formed as a substantially vertical direction of the axis of rotation 'and the axial direction of the inner groove 3 may be arranged in a substantially vertical direction. 15 Further, the present invention In the first embodiment, the light irradiation device 5 is disposed in the vicinity of the peripheral edge portion of the opening 2a of the outer tub 2. However, the cover 13 may be disposed to be slightly extended on the center of rotation of the inner groove 3. In 10, the amount of water in the washing tank 4 is adjusted to adjust the current or the energization time so that the concentration of the silver ions after the water supply is O.Olppm~lppm. By this, the sterilization and antibacterial properties of the laundry 14 are maintained. When the amount of washings, or the amount of water injected, is small, the concentration of silver ions is lowered. Further, when the amount of the laundry 14 is large, since the amount of water to be injected does not become much larger as the amount of the laundry 14, the silver ion concentration can be increased by the adjustment of the control unit 15. Further, the control device 15 performs control of the washing step and the washing and dewatering step 11 200902790. Specifically, the washing degree and the washing and dewatering step are controlled by the water injection operation, the "washing" operation, the drainage operation, and the dehydration operation.

However, in the rinsing and dehydrating step which is performed several times, at least one of them can be carried out once, whereby the antibacterial effect can be exerted. Further, when the final water refilling operation in the rinsing and dehydrating step is performed, silver ions are supplied from the electrolytic cell 10, so that silver ions can be used most efficiently, and the cleaning can be performed to eliminate bacteria and anti-a. Further, if d is present after the end of the final (four) water step, the light can be irradiated in the drying step, whereby sterilization and antibacterial can be performed more effectively. 20 ^ Wash _14 (4), anti-g treatment, the concentration of silver ions into the sputum. If the treatment of the wash 14 is the minimum amount (relative to the washing and filling of the secrets such as), if the concentration of 赖 _ 卯 m, high silver from the m / pain effect * the amount of the washing of the sputum will increase Degree, but the money solves the groove shot 'When the concentration of the miscellaneous material of the towel is unable to be charged == move, the phenomenon occurs from 1 to 1 and becomes 1ΡΡ_Γ Therefore, it is necessary to perform sterilization effectively. The right silver ion concentration is at 1 ppm, and under normal use 12 200902790, there is no case where the laundry 14 is colored due to silver ions. Further, in order to efficiently generate an active oxygen species such as a hydroxylation group to the bacterial cage attached to the laundry material 14, it is possible to enhance sterilization and antibacterial action by sterilization, and it is necessary to act by photocatalyst. A chemical oxygen species is formed. Therefore, the amount of silver attached to the laundry 14 is 〇〇〇1 in the range of cm2 to 0.30" g/cm2. Thereby, the consumption of the adhered silver can be minimized, and a group can be generated, and the table attached to the laundry 14 can be most effective, and the antibacterial fourth embodiment shows another embodiment of the washing machine according to the embodiment of the present invention. The time sequence diagram is a rinsing step after three cleaning steps. When "flush 2" and "flush 3" after ", order, first 1" are performed, silver ions are dissolved and light is irradiated. (A) Open the drain valve 7 and discharge the flushing water used in the "flushing bowl". (The inner tank 3 is rotated at a high speed for a predetermined time to perform intermediate dewatering, and the washing water contained in the washing strip becomes less. Listening speed, and (4) water supply has just been supplied to 15 washing tank 4. At this time, '(〇 〇 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ (9) When the flushing water is injected into the washing tank 4, the inner tank 3 can be forwardly rotated and reversed by the motor (driving device 12), and the washing material I4 is sand mixed in the inner crucible for a predetermined time and continues. The light is irradiated to change the position of the washing device 20. When the above-mentioned "flushing 2" operation is completed, the same operation as "flushing 2" is continued in "flushing 3", and then the process is switched to the dehydrating step. In the middle, the inner tank 3 is rotated at a high speed to perform dehydration of the washing and to illuminate the light. The human light is irradiated with the moonlight. The light irradiation device 5 is disposed near the peripheral edge portion of the opening 2a of the outer groove 2 13 200902790. And illuminating the light inside the inner tank 3. In the interior of the washing tank 4, The washing material 14 is rotated by the rotation of the inner tank 3, so that the washing water is also scattered. However, when the light irradiation device 5 is placed in the vicinity of the peripheral edge portion of the opening portion of the washing tub 4, When the light irradiation device 5 is placed at a lower portion 13 which is located near the lower end portion of the opening portion 2a of the outer groove 2 or the rotation center of the inner groove 3, it is less likely to be affected by water scattering, and may be more In the case where the light irradiation device 5 is provided in the upper portion near the peripheral edge portion of the opening portion 2a of the outer groove 2, it is possible to prevent the washing water from being contaminated and contaminated. The light is irradiated away from the position of the laundry 14 in the inner tank 3, so that the light is prevented from being blocked by the laundry 14 in the vicinity of the light irradiation device 5. Fig. 5 is a view showing the light irradiation device of the washing machine of the embodiment of the present invention. In Fig. 5, an electrode I? is formed on the substrate 16. The electrode 17 has a series of LEdi8 as a light source of the light irradiation device 5. The resistor 19 is set to 15 so that the forward current flowing to the LED 18 is a predetermined 値. In a typical LED, the current is set to 20 mA to 30 mA. In the middle, a plurality of LEDs 18 are connected in series. The LED 18 can also use one high output, but since the temperature rises at a high output, a heat dissipation structure is required, and it is advantageous from the viewpoint of the life to be dispersed into a plurality of. Further, the casing 20 houses the LEDs 18, and the wires 21 are connected to the electrodes 17 and the control device 15. The insulating material 22 is filled under the substrate 16, and the waterproof cover 23 is formed of methacrylic resin and has a thickness of 2. 〇mm. 320nm~visible light can pass through more than 90%. Generally used as transparent resin PET (polyethylene terephthalate 14 200902790 ester), PBT (polybutylene glycol ester), PEN (poly pair) The naphthalene phthalate), PC (polycarbonate), etc. have excellent visible light transmittance, but since the ultraviolet ray is hardly transmitted, the LED is not used as the waterproof cover 23 when ultraviolet light is used. When the LED uses ultraviolet light, in addition to the aforementioned methacrylic acid 5 grease, PFA (tetrafluoroethylene-perfluorofluoro-perfluoroalkoxyethylene), quartz glass, borosilicate glass, Glass such as nano-calcium glass does not have a degree of freedom in forming and is easily broken. Therefore, in the first embodiment of the present invention, a methyl propylene resin is used. The light irradiation device 5 has a waterproof cover 23 made of any one of glass, mercapto propylene resin, and PFA resin. Since the light source can be covered by such a waterproof cover 23, the visible light can be transmitted through the ultraviolet light by 80% or more, and the irradiated matter can be effectively sterilized. Further, when the light source is an ultraviolet light source, it may be an invisible light or a germicidal lamp or the like which is generally used. However, since the light irradiation device 5 is provided inside the washing machine body 1, it is suitable for an LED having a very small light source. Also, the LED 18 can be selected to be about 1 依 depending on the purpose. ~14〇. Orientation angle (angle of light emission: usually the illuminance is 〇 5 with respect to the luminosity 1 on the optical axis). In addition, the LED 18 can emit light of a wavelength of 350 nm to 66 〇 nm, and can select ultraviolet light, 2 〇 violet, blue, green, yellow, red or the like for monochromatic light or white depending on the purpose of use. By making the light source LED ’, the light source can be reduced and can be easily arranged in the second room. Further, since the angle of irradiation (orientation angle) can be changed by the configuration of the LED, the irradiation range in the inner tank 3 can be arbitrarily set. Fig. 6 is a view showing the sterilization effect of the washing machine of the first embodiment of the present invention. 15 200902790] The graph shows the relationship between the wavelength (color) of the LED 18 and the sterilization effect. The bacteria are suspended in the sterilized water, and after the bacteria are taken on the test cloth, the dish is washed into the washing machine, and after washing, the water-inducing antibacterial material is used to add water to the dehydration step, and the drying step is included (4). Shoot light. The second graph shows the ratio of the number of bacteria (8) of the test cloth remaining at this time to the number of bacteria (E〇) before the irradiation ("l〇gEL//E〇) relative to the wavelength of the LED. As can be seen from the results of Fig. 6, the wavelength of light (red) at a wavelength of 63 〇 is also effective, but the shorter the wavelength, the higher the sterilization effect, and the light source of the light irradiation device 5 is suitable for ultraviolet rays. Therefore, the light irradiation device 5 is preferably a light source containing ultraviolet light, and can effectively generate an active oxygen species such as a chemical group having a large sterilization effect by photocatalytic action, thereby improving the sterilization effect. As described above, the washing machine of the first embodiment of the present invention has the H groove 4 for accommodating the laundry 14; the photosensitive antimicrobial supply device ι (electrolyzer), 15 for making the light stimuli The light-irritating antibacterial material is eluted, and the light-irritating antibacterial material added to the water is supplied to the washing tub 4; and the light-irradiating device 5 is irradiated with the washing material 14 containing the photo-vibrating antibacterial material-added water. Therefore, when the light emitted from the light irradiation device 5 is irradiated to the photo-activated antibacterial material attached to the laundry 14 and the photo-activated antibacterial material supplied to the washing tank 4, water is generated by the action of 2 photocatalysts. An active oxygen species such as a large chemical group, and is sterilized by such strong oxidizing power. It can also be used for sterilization and antibacterial effects by using a light-sensitive antibacterial material and an active oxygen species, that is, low/initial. Further, since the oxidative decomposition is carried out by the active oxygen species, the antibacterial spectrum can be expanded, and the bacteria or mold other than coliform or κ-colored staphylococcus can also be exerted. 16 200902790 Two = anti-supply (4) has an electrolytic cell, which is supplied with metal ions into the water by electrolysis. As a result, since the metal element having photoexcitation is electrolytically eluted, the current and the energization time can be controlled to adjust the concentration of the metal element of the photoexcited water, and can be supplied to a predetermined concentration.
又於使具有光激作用之金屬元素溶出至流通於電 解槽10之水且供給顺_4，因此可藉由簡單之構成進行 光激抗g材添加水之生成與供給的控制。 又’在沖洗脫水步驟中，藉由將光照射至含浸有供給 10到洗衣槽4之絲抗n材添加权洗祕14，可使溶出於水 之光激抗菌材有效地含浸於洗務物14，並可藉由光觸媒作 用，生成除菌作用大之羥化基等活性氧種。 又’光照射裴置5係當洗滌槽4内之光激抗菌材添加水

照射領域，依各個領域任意設定照射方法。因此，可縮短 D又疋與照射對象之間的距離，並可於每一領域將光集中照 15射於照射對象。 又，也可藉由將LED18並聯，在沖洗時，可於脫水時 改變照射方法。沖洗時，洗滌物14會反覆進行被内槽3之旋 轉及擋板11抬起到上方後落下於光激抗菌材添加水之授摔 動作。 2〇 又，若朝内槽3之底部照射，則必定洗滌物14會被光照

又，藉由將複數光源配置於外槽2之開口部2a側之端周 緣部之不同位置，可由不同之方向照射光於洗滌物14上， 減少光照射不到的部分，可有效率地照射光。 (實施形態3) 15 第1 〇圖係本發明之實施形態3之洗衣機之光照射裝置 之截面圖，第11圖係本發明之實施形態3之洗衣機之光照射 裝置之特性圖。光照射裝置之基本構成與本發明之實施形 態1及2相同，因此僅就相異點說明。

而放射強度變強之LED27，並藉由將該等LED串聯，可任 意設定照射方法。 即，如本發明之實施形態2中所說明，沖洗時，點量在 光軸上具有最大強度之LED18點亮，脫水時則點亮LED18 5 與在遠離光軸上之位置具有最大強度之LED27。又，亦可 因應於洗滌物14之量而變化照射方法。即，當洗滌物14之 量少時，則點亮在光軸上具有最大強度之LED18，在洗滌 物14之量多時，則點亮LED18與在遠離光軸上之位置具有 最大強度之1^〇27。此時，1^5〇18及1^〇27也可如第10圖所 10 示，收納於一個殼體20内，又，亦可如第9圖所示，配置於 與外槽2之端周緣部不同之位置。 (實施形態4) 第12圖係本發明之實施形態4之洗衣機之光照射裝置 之裁面圖。光照射裝置之基本構成與上述本發明之實施形 15 態1〜實施形態3相同，因此僅就不同點作說明。 第12圖中，LED28係可視光之波長領域發光。除菌效 果大之紫外光的LED18中，可將至少1個置換成該LED28。 要除菌本來係使全部使用發出紫外線之LED18者較有效。 可是，由於人看不到紫外線，含有螢光劑之洗務物14等沒 20 有放入洗衣槽4的話’難以辨識為除菌中。因此，除菌中， 點亮紫外線之LED18時’同時點亮可視光LED28，藉此以 視覺方式通知為除菌中。 如第6圖所示’對於除菌係波長短者效果大。波長 630nm (紅色）之光也可得到除菌效果，但為了盡可能不損 23 200902790 及除菌效果，可視光LED28宜為具有46〇nm附近之波長（綠 色）者。 因此，由於本發明之實施形態4之洗衣機的光照射裝置 可作成可視光，因此可以視覺方式通知正在進行除菌動 5 作。又，藉由組合含有紫外光之波長不同之光源，可藉由 光觸媒作用’有效地生成除菌作用大之羥化基等等活性氧 種。 (實施形態5) 本發明之洗衣方法包含：將光激抗菌材添加水供給至 10洗衣槽4之光激抗菌材添加水供給步驟、使洗務物含有光激 抗菌材添加水之含浸步驟、及於含有光激抗菌材添加水之 洗滌物照射光之步驟。 藉由使光激抗菌材添加水接觸洗滌物，溶出於水之光 激抗菌材會附著於洗滌物。藉由將光照射於該光激抗菌 15材，藉由光觸媒作用生成除菌作用大之羥化基等活性氧 種，並藉由該活性氧種之氧化作用分解細菌。因此，藉由 光激抗菌材及活性氧種，即使為低濃度之抗菌材，也可有 效地進行洗滌物之除菌、抗菌。又，利用活性氧種進行之 氧化分解’可擴大抗菌範圍，對大腸菌或黃色葡萄球菌以 20 外之細菌或黴菌也可發揮效果。 又’本發明之實施形態中，係顧銀作為光激抗菌材， 並於電解槽U)内設置銀電極，藉由電氣分解來調整溶解於

the control of the generation and supply of the photo-induced anti-g material addition water can be performed by a simple configuration. In addition, in the rinsing and dehydrating step, by irradiating light to the wire anti-n material added with the supply 10 to the washing tank 4, the light-sensitive antibacterial material can be effectively impregnated with the washing material. 14. An active oxygen species such as a hydroxylation group having a large sterilization effect can be produced by photocatalytic action. In addition, when the light-irradiating antibacterial material is added to the water in the washing tank 4, or after the light-activated antibacterial material is added, the light is irradiated onto the washing material 15 14 ', thereby irradiating the light to the light. The light-sensitive antibacterial material is added with the water-exposed laundry 14, and the active oxygen species can be efficiently produced. (Table 1) shows the sterilization effect of the mold of the washing machine of the first embodiment of the present invention. The mold is suspended in the sterilized water, and after the bacteria are taken up in the test cloth, it is placed in the washing tank 4 together with the laundry 14, and after washing, the light is irradiated by adding light to the antibacterial material (silver ion). The sterilization rate of the mold is determined in the case of the rinsing and dehydrating step and the rinsing and dehydrating step without irradiating the light. It can be understood that the sterilization rate of the mold is greatly improved after the light irradiation as compared with the case where the light is not irradiated, and the mold can be effectively removed by causing the light to touch the silver ion. 17 200902790 [Table 1] Table 1 Silver ion + light effect sterilization rate (%) Bacteria (Staphylococcus aureus) Mold (Mycobacterium) Only silver ion >99 22 Silver ion + light >99 90 ( Table 2) shows the sterilization rate of bacteria relative to the concentration of photoactivated antimicrobial material (silver ion). The silver ion concentration varies depending on the amount of the laundry 14. 5 Therefore, for the amount of washing materials of 0.5 kg, 3.5 kg, and 7 kg, the silver ion concentrations are 0.1 ppm, 0.03 ppm, and 0.1 μm, respectively. The bacteria are suspended in the sterilized water, and after the bacteria are taken on the test cloth, they are placed in the washing tank 4 together with the laundry 14, and after washing, the light is irradiated with water by a photo-activated antibacterial material (silver ion), and is washed. After the dehydration step, the sterilization rate of the bacteria was determined. Even if the silver ion concentration 10 is a low concentration of O.Olppm, a high bacterial sterilizing rate can be obtained by irradiating light. [Table 2] Table 2 Silver ion concentration and sterilization rate Silver ion concentration Clothing type sterilization rate (ppm) (kg) (%) 0.01 0.5 >99 0.03 3.5 >99 0.10 7 >99 Figure 7 A A schematic cross-sectional view showing a method of light irradiation 15 of a washing machine in accordance with a first embodiment of the present invention, and a seventh section showing a light-emitting view of the other light irradiation of the washing machine 18 200902790, and a seventh drawing showing the other light irradiation of the washing machine. A rough outline of the method. As shown in Fig. 7A, the light irradiation device 5 can be set to be irradiated toward the bottom portion of the inner tank 3 (the portion where the water is excited during the rinsing (4) is added with water storage). In this case, by using a smaller orientation angle, it is possible to concentrate on the narrow range and to illuminate the light to promote the sterilization effect of the portion. At the time of rinsing, the strip 14 is repeatedly subjected to the action of adding the water to the photo-activated antibacterial material by the rotation of the inner tub 3 and the baffle (10). Therefore, if the bottom portion of the inner tank 3 is irradiated, the laundry 14 will be irradiated with light, and the laundry 14 can be sterilized. Therefore, the light is irradiated toward the bottom of the inner tank 3 by the light irradiation device 5, and σ is surely carried by the light-sensitive material-added water and the laundry 14 impregnated with the light-sensitive antibacterial material-added water. By the light irradiation device 5, the water surface irradiation light of the photo-activated antibacterial material in the inner tank 3 is added to the water surface of the water-repellent material, which can be sufficiently impregnated on the silk material 14 exposed on the water surface and the laundry material 14 which is present on the water surface. The light is efficiently emitted while the light is excited by the light (4) material. ~ The washing tank 4 has a groove 2 disposed in the outer groove 2, and an inner groove 3' which is rotatable and disposed in the inner groove 2, and is driven by the motor 12 (drive: set) in the inner groove 3 Wash the seam 14. Further, by changing the washing material Μ = illuminating light, the _ overlapping yarn 14 is replaced by the inner container 3 to be exposed. Therefore, the filament 14 can be completely irradiated to the light, and the reactive oxygen species of the photo-excited metal material can be generated to enhance the effect of removing the ®. Further, the inner groove 3 is reversely swirled and uniformly irradiated. "Scrubbing 14 of the mixing effect, the light 19 200902790, by the speed of the washing object by the baffle 11 to fall, for example, 45 rotation / minute to rotate the inner groove 3, the light can be irradiated to the laundry 14, The laundry can be effectively discarded, and the light can be uniformly irradiated to the laundry. The light irradiation device 5 can be used as shown in Fig. 7B, and the radiation can be used at a large angle of 5 shots. In this case, although For example, the f7A map focuses on a narrow range to illuminate light, but it can uniformly illuminate the inner groove 3 to remove _. Further, since the inner groove is generally made of a metal such as stainless steel, when the LED 18 having a large orientation angle is used, The light is reflected on the surface of the inner groove 3, and the addition of light can also reach the opportunity of the laundry 14 which is not directly contacted by the LED 18, and is sterilized by 10. However, in this case, direct radiation is not exposed. The outside of the washing tank 4, that is, the leakage through the cover 13. Thus, the washing tank 4 can effectively use light to remove bacteria. Moreover, especially when the wavelength of the ultraviolet light 2LED18 is used, The composition of the leakage can suppress the influence on the human body. Therefore, by setting the orientation angle of the light source of the light irradiation device 5 or the setting angle of the light source, light can be efficiently introduced into the inner groove 3 without directly irradiating the outside of the inner groove 3. The ultraviolet light can be reduced. The effect on the human body. The 'lighting device 5 can also be used to illuminate the wider range of the cleaning tank 4 using a plurality of LEDs 18' as shown in Fig. 7C. By using an LED 18' with an orientation angle of 20 In the different places, a plurality of irradiated portions having a large intensity can be formed and irradiated in a wide range, so that the same effects as in the case of FIG. 7B can be obtained. (Embodiment 2) FIG. 8 is an embodiment of the present invention. (2) The light irradiation device of the washing machine of the second embodiment of the present invention has the same configuration as that of the light irradiation device of the washing machine according to the first embodiment of the present invention. In the first embodiment of the present invention, the plurality of LEDs 18 are connected in series. However, in the second embodiment of the present invention, the five LEDs 18 are connected in parallel (the L1 to L4 of the figure) and are arranged corresponding to the respective LEDs 18. Resistance 1 9 (R1 to R4 in Fig. 8) Further, by providing the switching device 24, it is possible to arbitrarily set the illumination method of the plurality of LEDs 18 by using LEDs of different orientation angles, and it is impossible to emit light even if there is a problem with any of the light sources. In addition, Fig. 9 is a schematic cross-sectional view showing a light irradiation method of the washing machine according to the second embodiment of the present invention, and as shown in the figure, a plurality of LEDs 25 are shown. And 26 are disposed at different positions of the peripheral edge portion of the opening portion 2a of the outer tank 2, and the irradiation field of the divided light is arbitrarily set in accordance with each field. Therefore, the distance between the D and the object to be irradiated can be shortened, and In each field, the light is concentrated on the illuminated object. Further, by connecting the LEDs 18 in parallel, the irradiation method can be changed during the rinsing at the time of rinsing. At the time of rinsing, the laundry 14 is repeatedly subjected to the rotation by the inner tank 3 and the baffle 11 being lifted up and then dropped into the light-activated antibacterial material to add water. 2〇 Further, if the bottom portion of the inner tank 3 is irradiated, the laundry 14 is necessarily irradiated with light to sterilize the laundry 14. On the other hand, at the time of dehydration, since the laundry 14 is rotated at a high speed, it can be attached to the inner wall of the inner tank 3 by centrifugal force. Therefore, in the dehydration, in addition to the LED 25 being irradiated to the lower portion of the inner tank 3, the inner portion of the inner tank 3 can be irradiated by the LED 26, whereby the light 21 200902790 can be efficiently irradiated to the laundry 14 for sterilization. Further, the illumination method of the LEDs 25 and 26 can be set in accordance with the amount of the laundry 14. In the first embodiment of the present invention, the concentration of silver ions is changed in accordance with the amount of the detergent material 14, but the irradiation method of changing the light according to the amount of the laundry 14 may be described. That is, when the amount of the laundry 14 is small, the LEDs 25 that illuminate the lower portion of the washing tub 4 can be illuminated, and when the laundry 14 is large, the LEDs 25 and 26 can be spotted to efficiently sterilize. Further, by irradiating the same place in the inner tank 3 with a plurality of light sources, the portion irradiated with light can be concentrated to increase the production efficiency of the active oxygen species. Moreover, by setting a plurality of light sources, the load of each light source can be reduced, and the life of the light source can be increased. Further, by arranging the plurality of light sources at different positions on the peripheral edge portion of the opening portion 2a side of the outer tank 2, the light can be irradiated onto the laundry 14 in different directions, and the portion which is not irradiated with light can be reduced, and the light can be efficiently irradiated. Light. (Embodiment 3) FIG. 11 is a cross-sectional view showing a light irradiation device for a washing machine according to Embodiment 3 of the present invention, and FIG. 11 is a characteristic view of a light irradiation device for a washing machine according to Embodiment 3 of the present invention. The basic configuration of the light irradiation device is the same as that of the first and second embodiments of the present invention, and therefore only the differences will be described. Generally, the LED used has the maximum intensity of radiation on the optical axis, and 20 is enlarged as the angle is amplified by the optical axis, and the intensity of the LED 27 is as shown in Fig. 11, and has a line on the display optical axis (angle of 0°). The radiation intensity is small, and the intensity tends to increase as the angle is enlarged by the optical axis. Such an LED 27 is formed as a recessed portion at the front end of the LED as shown in Fig. 10, and the front end is smoothed. At least one of the plurality of LEDs 18 is formed as an LED 27 whose radiation intensity is increased by an optical axis of 22 200902790 at such an angle, and by arranging the LEDs in series, the irradiation method can be arbitrarily set. That is, as described in the second embodiment of the present invention, when flushing, the LED 18 having the maximum intensity on the optical axis is lit, and when dehydrating, the LED 18 5 is illuminated and the LED 27 having the maximum intensity at a position away from the optical axis. . Further, the irradiation method may be changed depending on the amount of the laundry 14. That is, when the amount of the laundry 14 is small, the LED 18 having the maximum intensity on the optical axis is illuminated, and when the amount of the laundry 14 is large, the LED 18 is illuminated and has the maximum intensity at a position away from the optical axis. ^〇27. At this time, 1^5〇18 and 1^〇27 may be housed in one casing 20 as shown in Fig. 10, or may be disposed at the end of the outer tank 2 as shown in Fig. 9. The peripheral part is different. (Fourth Embodiment) Fig. 12 is a plan view showing a light irradiation device of a washing machine in accordance with a fourth embodiment of the present invention. The basic configuration of the light irradiation device is the same as that of the above-described embodiment 1 to the third embodiment of the present invention, and therefore only differences will be described. In Fig. 12, the LED 28 emits light in the wavelength range of visible light. In the LED 18 of the ultraviolet light having a large sterilization effect, at least one of the LEDs 18 can be replaced with the LED 28. It is more effective to remove all of the LEDs that emit ultraviolet light. However, since the human is not exposed to ultraviolet rays, the laundry containing the phosphor 14 or the like is not placed in the washing tank 4, and it is difficult to recognize that it is in the sterilization. Therefore, in the case of sterilizing, when the LED 18 of the ultraviolet ray is turned on, the visible light LED 28 is simultaneously lit, whereby it is visually notified that it is sterilized. As shown in Fig. 6, the effect on the short wavelength of the sterilization system is large. The light having a wavelength of 630 nm (red) can also be sterilized, but in order to minimize the damage of 23 200902790 and the sterilization effect, the visible light LED 28 should preferably have a wavelength (green) near 46 〇 nm. Therefore, since the light irradiation device of the washing machine according to the fourth embodiment of the present invention can be made visible light, it is possible to visually notify that the sterilization operation is being performed. Further, by combining light sources having different wavelengths of ultraviolet light, an active oxygen species such as a hydroxylation group having a large sterilization effect can be efficiently produced by photocatalytic action. (Embodiment 5) The washing method of the present invention includes a step of supplying a photo-activated antibacterial material-added water to the 10th washing tank 4, and a step of adding the water to the washing agent containing the photo-vibrating antibacterial material, And a step of irradiating light to the laundry containing the light-activated antibacterial material and adding water. By bringing the light-sensitive antimicrobial material into contact with the laundry, the photo-activated antimicrobial material dissolved in the water adheres to the laundry. By irradiating light onto the light-sensitive antibacterial material 15, an active oxygen species such as a hydroxylation group having a large sterilization effect is generated by photocatalytic action, and the bacteria are decomposed by oxidation of the active oxygen species. Therefore, the photo-excited antibacterial material and the active oxygen species can effectively perform sterilization and antibacterial action of the laundry even at a low concentration of the antibacterial material. Further, the oxidative decomposition by the active oxygen species can expand the antibacterial range, and can also exert effects on bacteria or molds other than coliform or Staphylococcus aureus. Further, in the embodiment of the present invention, silver is used as the photo-active antibacterial material, and a silver electrode is provided in the electrolytic cell U), and the dissolved concentration dissolved in water is adjusted by electrical decomposition, but in addition to silver, Recording and copper can be used as photo-activated antibacterial materials with antibacterial action. By categorizing the objects to be used for the sterilization and antibacterial microorganisms 24 200902790, the most suitable sterilization and antibacterial effects can be expected. For example, copper and nickel are effective in terms of zinc and algae relative to mold. I.
