Description of the Invention: [Technical Field] The present invention relates to stain removal, and in particular, the present invention relates to a method and apparatus for removing a stain from a target object. [Prior Art] It is difficult to remove some stains by a laundry or washing machine (most notably stains caused by some foods (for example, carrot and spinach). Matte-free processing devices for stains caused by such foods are currently known. SUMMARY OF THE INVENTION Clothes are usually bleached in the sun. Recently, it has been found that various stains caused by foods (for example, carrots, spinach, tomatoes, berries, red wine, etc.) can be almost completely removed by the sun, and they are difficult to remove at the laundry. The inventors have performed some experiments to mimic the effects of using artificial light. Although most people attribute the bleaching effect of the sun to the uv portion of the sun, these experiments have shown that the uv portion of the sun is a small part of the key factor in removing stains from food, possibly because of such foods (such as Hu The radish or tired vegetables mainly absorb some of the lower visible wavelengths (ie, 400 nm to 5 Å nanometers). Some of the wavelengths from 400 nm to 5 Å around a purple LED array also work on stains caused by spinach, etc., but are less energetic than a blue LED array. Thus, with one wavelength of around 460 nm, the blue LED can act as an effective source for removing (by illumination) one of the stains caused by some food products. And so far, there is no device that can mimic this effect, this light processing device is very convenient for stain removal, especially when there is no sunlight. In view of the lack of convenience and effectiveness in removing stains caused by food, it is advantageous to implement a method and apparatus for removing a stain from a target article. According to an embodiment of the present invention, there is provided a method of removing a stain from a target object, the method comprising the steps of: placing a light source at a predetermined distance from one of the stains; The light having a wavelength between one of 400 nm and 5 nanometers illuminates the stain, wherein the light produced has a predetermined light intensity at the surface of the stain. Illumination with light having a wavelength between one of 400 nm and 500 nm can remove some stains from the target object (for example, fabric) (for example, stains caused by food) . Moreover, in accordance with another embodiment of the present invention, there is provided an apparatus for removing a stain from a target article, the apparatus comprising: a light source configured to produce between 4 nanometers to a light of one wavelength between the ranges of 5 nanometers; a support configured to set a distance between the light source and the stain; wherein the light source is configured to generate light to use the stain A predetermined light intensity at the surface of the spot illuminates the stain. Advantageously, the apparatus includes an of 3f -1·*· -5 4- Z At 7匕 child head configured to inject a fluid to wet the target article. With the fluid provided by a showerhead (for example, water), it is easier to remove a stain from the target object 160403.doc 201239152. [Embodiment] Other features, objects, and advantages of the invention will be apparent from the description of the accompanying claims. The same or similar reference symbols refer to the same or similar devices or circuits. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional side elevational view of one embodiment of an apparatus for removing a stain according to the present invention. As shown in FIG. ,, the apparatus 10A for removing a stain 101 from a target object 100 includes a light source u and a support 12°. FIG. 2 is a bottom view of one embodiment of the apparatus of FIG. The light source 11 is configured to produce light having a wavelength between 4 nanometers and 5 nanometers. And the support body 12 is configured to set a distance between the light source 丨丨 and the β 污 stain 1 1 1 in order to achieve a light intensity and an illumination area on the surface of the stain 1 〇 1 Light source 11 is further configured to generate light to illuminate the stain at a surface of the stain 101 with a predetermined light intensity. And the δ-Xuan source 11 emits light toward the stain 101 in a dispersed manner as indicated by the directional arrows in FIG. Optionally, the device 10 can further include a timer configured to set a predetermined duration, wherein the light source 11 illuminates the stain 10 for less than or longer than the predetermined duration. Optionally, the light source 11 can include at least one blue LED. In some of the above embodiments, the light source 11 is further configured to produce light that is dependent on the intensity of one of the sizes of the stain 101. For example, if the stain 101 occupies a relatively large area on the fabric 100, the light can be adjusted 160403.doc

Therefore, the intensity of the light source 11 can be set higher to ensure that the light intensity at the surface of the stain 101 is sufficiently strong. Moreover, of course, the adjustment of the distance between the light source 11 and the stain 1 〇 1 can be achieved by using the support body 12. Preferably, the predetermined light intensity is not less than 50 W/cm 2 so that the stain 1 〇 1 can be removed in a relatively short time. It should be understood that the light intensity referred to above generally means the intensity of light at the surface of the target article (for example, a fabric) and the intensity of light at the location of the stain. In general, the intensity of the light can depend on the amount of optical power emitted by the source and the spot size. Since the LED has a scattered beam, the spot size can depend on the angle of dispersion and the distance of the LED (or other dispersed source) from the fabric. For example, the experiments were performed using a light output power of one of 7 〇〇 mW and a dispersion angle of one of 120 degrees. In the experiment, the distance between the source and the stain is approximately 5 mm' resulting in a spot size of 7.3 mm and a spot area of 2.4 cm2, and thus one of approximately 300 m W/cm2 Average intensity. Therefore, it is easy to achieve an intensity of 5 〇 m W/cm 2 using currently available LEDs. For the device 10 A, preferably, the preset light intensity is set depending on the type of stain. If the stain 101 is found to be stubborn, for example, since the stain is caused by red fruits such as red wine or berries, the preset light intensity can be set to a high value (for example, 9 〇 w/cm 2 ) ). And if the stain 1〇1 is less stubborn, for example, because the stain is caused by spinach, carrot, or tomato which is more sensitive to light, one light intensity of 5〇w/cm2 is enough to be 160403 .doc 201239152 is used to remove this stain. 3 is a cross-sectional side view of another embodiment of an apparatus for removing smudges in accordance with the present invention. As shown in Figure 3, the device hall may further include a spray head 13 configured to eject a fluid 14, such as 'water, to wet the target article 1 (i.e., have the stain) Ι〇ι one fabric). The device has been used in a simple manner. For example, when the clothes are taken out of the washing machine and noticed that a stain (for example, a stain caused by food) is not removed, the wet clothes are placed on the table and the device is placed in the rain. on. The light source u is turned on, properly positioned on the stain 1 , and the stain is checked after a certain time. If it still exists, you can continue processing. And if the garment is dry and the stain has not been removed, the spray head can be configured to spray some water to re-wet the stain to effectively continue the stain removal process. 4 is a flow chart of a method for removing a stain from a target object in accordance with an embodiment of the present invention. As shown in Figure 4, the method includes a step S1 and a step S2. In step S1, a light source is placed at a predetermined distance from one of the stains. In step S2, the stain is illuminated with light generated by the light source having a wavelength between 4 nanometers and 5 nanometers, wherein the light is generated at the surface of the stain Has a preset light intensity. Figure 5 illustrates another step S3 of one of the methods of removing a stain from a target article in accordance with another embodiment of the present invention. In step S3, wetting of the target object is performed. 160403.doc 201239152 and in some cases, in cooperation with step 83, the illumination of step s2 may have a better stain removal effect. And if the stain is not completely removed after the illumination of step 82, as the case may be, the step coffee is again performed to re-wet the target object having the stain. The illumination of step 82 is then continued as indicated by the dashed arrows in FIG. In order to obtain a desired duration of illumination in step S2, in some embodiments, the method of removing the stain from the target object further comprises two additional steps: depending on the type of stain, set for illumination duration One of the timers, and when the timer expires, turns off the light source to stop illumination. Prior to step S2, depending on the type of stain, one of the illumination durations is selected to correspond to the timer setting. And when the timer expires, the light source turns off to stop illumination. With these two additional steps, there is not much or too little illumination for a given stain type. In general, illumination with a high light intensity will help to remove the stain in a relatively short period of time. Therefore, preferably, in some of the above embodiments, the predetermined light intensity on the stain is at least 5 〇 w/cm 2 . It should be understood that the preset light intensity is set depending on the type of stain. If there is a stubborn stain (for example, red fruit stain (red wine, berry)), the preset light intensity can be set to a high value (for example, 9〇w/cm2) ^ and if § hai The stain is less stubborn (for example, the stain is caused by spinach, carrots or tomatoes), and one of the 50 W/cm2 light intensity is sufficient to remove the stain. In some experiments, according to one embodiment of the invention, one of the 300 m W/cm light intensities allowed the slow dish to be removed in 5 minutes, but the carrot took approximately 60 minutes. At one light intensity of m W/cm2, remove a spinach stain 160403.doc 201239152 minutes and 6 hours corresponding lighting time can be about 30 respectively. In some of the above examples, the light source can be A blue LED array is included to produce light having a blue color of between 4 nanometers. There is no "one of the surrounding conditions". The above example - this sentence - includes a step for setting the power of the light source depending on the size of the stain. Therefore, if the stain occupies the One of the fabrics, for the large area, can adjust the distance between the light source and the stain to achieve the spot size completely covering the stain, and the power of the light source can be set higher because of A ' To ensure that the light intensity at the surface of the stain is sufficiently strong. Figure 6 depicts one of the stain removal effects during the illumination time of one of the devices of Figure 3 using the following experimental conditions: Cleaning the target prior to use Object ιοο (for example, a t-shirt); put food (spinach and carrot) on the t-shirt to form a tired stain 1 〇 1 1 and a carrot _ stain 1 0 12, etc. The dividing line is drawn by the dotted line in the figure 且 and the t-shirt is dried at night; the t-shirt is washed with detergent in a short program (15 minutes); at a light intensity of about 〇3 w/em2 The device of Figure 3 processes a slightly wet stain 101 1 and stain 1012 due to cleaning, and within the device 10B The light source 11 is in the form of a blue LED having a wavelength of 460 nm. As shown in Fig. 6, the gradual lengthening processing time is shown in Figs. 6A to 6E (t = 0.2 minutes, 5 minutes, 20). A plurality of stains are removed within minutes, 3 hours, and finally, the stains are almost completely removed after 3 hours of illumination.
