The specific embodiment
Come with reference to the accompanying drawings embodiment more of the present utility model are elaborated.It is pointed out that such embodiment does not have the effect that limits the utility model scope.
(embodiment 1)
Fig. 1 is the structural section figure of the washing machine among the utility model embodiment 1, and Fig. 2 is the oblique view of the electrolytic cell in this washing machine, and Fig. 3 is the impulse stroke figure of this washing machine.
As shown in fig. 1, body 1 inside of washing machine is provided with: outer bucket 2 and be arranged in the outer bucket 2 and can rotate freely interior bucket 3.Outer bucket 2 and interior bucket 3 have been formed washtub 4.The leading flank of outer bucket 2 is provided with opening portion 2a, is provided with light irradiation device 5 near the periphery of opening portion 2a.The bottom of outer bucket 2 and an end of drainpipe 6 link, and drainpipe 6 links with draining valve 7, are used for the washings in the washtub 4 are discharged.When washtub 4 adds water, open the water intaking valve 8 on the water inlet pipe 9, in washtub 4, add water through electrolytic cell 10.
The face of rearward toppling over of the face side of outer bucket 2 is provided with opening portion 2a, and this opening portion 2a is covered in the mode that opens and closes freely by cover 13.After cover 13 opened, just inwardly drop into washings or therefrom take out washings in the bucket 3.Because cover 13 is arranged on the face of tilted rearward, so the input/taking-up of the washings of need not bending over just can finish.Therefore, adopt after the above-mentioned formation, can improve the problem of the inconvenient operation from the washing machine of opening portion input/taking-up washings 14 of being provided with laterally or up.
The operation of 15 pairs of draining valves 7 of control device, water intaking valve 8, motor 12 is controlled.
In box body 31, have under the state of water existence,, the metal ion stripping of the formation metal of electrode 32 will be arranged from the anode-side of electrode 32 when when electrode 32 applies the voltage of regulation.In electrolytic cell 10, apply stripping and the non-stripping that voltage can be selected metal ion by having or not.
In addition, by the size and the voltage application time of control electric current, can be controlled the stripping quantity of metal ion.If electric current in electrolytic cell 10 for a long time towards folk prescription when mobile, the electrode 32 that constitutes anode-side will constantly consume, simultaneously, impurities such as the calcium in the water will harden with the form of metal oxide film on the electrode 32 that constitutes cathode side.
In addition, on the surface of electrode 32, also can produce the chloride and the sulfide of the composition metal of electrode 32.Because salt and sulfide can cause the decreased performance of electrolytic cell 10, so adopted the formation that makes the polarity generation counter-rotating of electrode 32 by the electrode drive circuit that does not illustrate among the figure in the present embodiment.
Next, the working condition to the washing machine in the present embodiment 1 is described.During laundry, at first open cover 13, inwardly drop into washings 14 and washing powder in the bucket 3, make washing machine begin operation then.After the operation beginning, at first, drive interior bucket 3 by motor 12 and rotate, begin to carry out washing stroke from the water inlet pipe 9 outside bucket 2 interior water that inject ormal weight.When 3 rotations of interior bucket, baffle plate in the washings 14 in being contained in the bucket 3 is set on the internal face of bucket 3 11 is mentioned along direction of rotation, will fall again after mentioning certain height, and such stirring operation constantly repeats, and realizes washing by knocking cleaning function.
After the washing of having carried out the stipulated time, dirty cleaning solution is discharged from drainpipe 6.Then, carry out the dehydrating operations that bucket 3 rotates at a high speed in making, cleaning solution contained in the washings 14 is dewatered; Afterwards, add the silver ion that generates by 10 pairs of water that inject from water inlet pipe 9 of electrolytic cell, such water is added in the outer bucket 2, implements the rinsing stroke.In such rinsing stroke, the washings 14 of bucket in 3 also is that rotation along with interior bucket 3 is raised earlier, falls by baffle plate 11 in being contained in, and constantly carries out stirring operation, carries out the rinsing washing.
After the rinsing washing of having carried out the stipulated time, rinsing liquid is discharged from drainpipe 6.Then, carry out the dehydrating operations that bucket 3 rotates at a high speed in making, make rinsing liquid dehydration contained in the washings 14, also come to an end to this rinsing dehydration stroke.In addition, in rinsing dehydration stroke, also carry out illumination and penetrate by 5 pairs of washings 14 of light irradiation device and the rinsing liquid that is added with metal ion water.
In addition, if cover 13 is also made by translucent material, except the light of light irradiation device 5, the light of room lighting also can shine in the interior bucket 3, thereby can further improve the light bacteria-eliminating efficacy.
In addition, if washtub 4 is the formation with inclination angle that the front portion upwarps, adds cover 13 and made by translucent material, except the light that light irradiation device 5 sends, the light of room lighting also can be shining into easilier, thereby can improve the light bacteria-eliminating efficacy.This be because, compare with the existing lid of being arranged to horizontal direction, washtub 4 upwarps ground during run-off the straight with front portion, an inclination angle, even if the cover area is the same, also can be shining into more scattered light.
In addition, though the pivot of bucket 3 is for roughly being in the rotating shaft 3b of incline direction in the present embodiment 1, and the direction that the axis direction of interior bucket 3 is arranged in from rear side to face side is inclined upwardly, but the pivot of interior bucket 3 also can be the rotating shaft that roughly is in horizontal direction, and promptly the axis direction of interior bucket 3 also can be arranged on the direction of basic horizontal.In addition, the pivot of interior bucket 3 also can be the rotating shaft that is in vertical direction basically, and promptly the axis direction of interior bucket 3 can also be arranged on the vertical substantially direction.
In addition, though outside light irradiation device 5 is arranged in embodiment 1 of the present utility model near the circumference of bucket 2 opening portion 2a, also be no problem on the cover 13 on the extended line of barrels 3 pivot even be located in roughly being in.
In addition, electric current in electrolytic cell 10 or conduction time are adjusted according to the water yield of washtub 4, make the concentration of silver ions that adds behind the water become 0.01ppm～1ppm.So, the degerming of washings 14, anti-microbial property just can be kept.Under the few situation of the amount of washings 14 or water injection rate, control device 15 reduces concentration of silver ions; On the contrary, under the many situations of the amount of washings 14, because not being amount with washings 14, do not increase pro rata water injection rate, so control device 15 will make the concentration of silver ion heighten.
In addition, control device 15 is also controlled washing stroke and rinsing dehydration stroke, is in washing stroke and rinsing dehydration stroke water flood operations, washing (rinsing) operation, drain operation and dehydrating operations to be controlled particularly.
As shown in Figure 3, embodiment 1 of the present utility model carries out twice rinsing dehydration stroke (being made of water filling, rinsing, draining and dehydration), and is dissolved into silver ion in each water flood operations in the water of water inlet pipe 9.In addition, when carrying out water filling, rinsing, draining and dehydrating operations, 5 pairs of washings of light irradiation device 14 and the water that is dissolved with silver ion carry out illumination and penetrate.
In addition, in order to bring into play degerming, antibacterial effect to greatest extent, embodiment 1 of the present utility model carries out the silver ion dissolving in rinsing dehydration stroke each time and illumination is penetrated.But, under rinsing dehydration stroke carries out repeatedly situation,, just can give play to the degerming antibacterial effect as long as carry out once at least in any stroke therein.
And, if supply with silver ion from electrolytic cell 10 in the water flood operations of rinsing dehydration stroke the last time, can make the utilization ratio of silver ion reach the highest, washings 14 is carried out degerming and antibiotic.In addition, also have under the situation of drying stroke after dehydration stroke the last time finishes, also can be to carry out in the clothing stroke illumination and penetrate, can more effectively realize degerming, antibiotic like this.
When washings 14 was carried out degerming, antibacterial treatment, the concentration of silver ion was important factors.If washings to be processed 14 is (for the water of washtub was 12L, washings was 0.5kg) under the minimum situation, concentration of silver ions is set at 0.01ppm, just can give play to degerming, antibacterial effect fully.Along with increasing of the amount of washings 14, concentration of silver ions also will improve, but along with the rising of concentration of silver ions, deposited phenomenon can occur in the water of electrolytic cell 10.This deposited phenomenon begins to take place from 1ppm, and silver ion will become and can not be dissolved in the water fully.Therefore, in order to realize high efficiency degerming, concentration of silver ions need be set at and be less than or equal to 1ppm.And, be less than or equal to 1ppm as long as concentration of silver ions is set at, silver ion can not take place in normal the use make the painted phenomenon of washings 14.
In addition,, also need to generate hydroxyl free radical isoreactivity oxygen base to carrying out degerming, antibiotic for effectively by photocatalysis attached to the microorganisms such as bacterium on the washings 14.For this reason, the amount attached to the silver on the washings 14 is set to 0.001 μ g/cm
2～0.30 μ g/cm
2Like this, not only can make the consumption of silver reach minimum degree, can also generate free radical, generate hydroxyl free radical isoreactivity oxygen class free radical expeditiously, improve the degerming antibacterial effect from silver attached to the surface of washings 14.
The another kind of time sequential routine figure of the washing machine of the utility model embodiment 1 has been shown among Fig. 4, and wherein the rinsing stroke behind the washing stroke carries out 3 times altogether.In " rinsing 2 " and " rinsing 3 " that " rinsing 1 " carried out afterwards, carry out silver ion dissolving and illumination and penetrate operation.As shown in Figure 4, after opening draining valve 7 used washings discharge (A) in " rinsing 1 ", interior bucket 3 carries out high speed rotation in official hour, carry out the centre and dewater; When washings contained in the washings tail off, make low speed rotation into, open water intaking valve 8, add water (B) to washtub 4.At this moment, electrolytic cell 10 is carried out the energising of stipulated time, is added into silver ion in the washings that are added in the washtub 4; Then, carry out illumination by light emitting diode (light irradiation device 5) and penetrate (C).When the washings in being added to washtub 4 reach ormal weight, make interior barrel 3 just changeing, reversing (D) by motor (drive unit 12), washings 14 in the internal bucket 3 stirs in official hour on one side, and the position of washings 14 is changed, and penetrates Yi Bian carry out illumination continuously.
Behind the EO of above-mentioned " rinsing 2 ", then in " rinsing 3 ", carry out and " rinsing 2 " identical operations, enter the dehydration stroke then.In the dehydration stroke, Yi Bian bucket 3 is done rotation at a high speed in making, washings is dewatered, penetrate Yi Bian carry out illumination.
Below light irradiation device 5 is specifically described.Light irradiation device 5 is set near the circumference of opening portion 2a of outer bucket 2, and the inboard of bucket 3 is carried out illumination and penetrated inwardly.In the inside of washtub 4, washings 14 also and then rotates when rotating owing to interior bucket 3, so washings can splash.But, if light irradiation device 5 is located near the circumference of opening portion 2a of washtub 4, with near light irradiation device 5 for example is located at the circumference of opening portion 2a of outer bucket 2 bottom or be located at roughly be in situation on the cover 13 on the extended line of pivot of bucket 3 compare, be not vulnerable to the influence of the water that splashing, can internally carry out illumination in the bucket 3 with very high efficient and penetrate.
In addition, near the top of the circumference of the opening portion 2a of bucket 2, can prevent because of adhering to washings dirty outside light irradiation device 5 is arranged on.In addition, owing to can penetrate, can prevent that light from being taken place by the situation that near the washings 14 the light irradiation device 5 stops from carrying out illumination away from the position of the washings 14 in the interior bucket 3.
Fig. 5 has been used to represent the summary sectional view of light irradiation device of the washing machine of the utility model embodiment 1.As shown in Figure 5, be formed with electrode 17 on the substrate 16.The light source of light irradiation device 5 is a light emitting diode 18, and light emitting diode 18 is connected in series with above-mentioned electrode 17.Resistance 19 is set to and makes the forward current that flows through in the light emitting diode 18 become the value of regulation.In light emitting diode, above-mentioned current value generally is set to 20mA～30mA.
In Fig. 5, a plurality of light emitting diodes 18 are connected in series mutually.Light emitting diode 18 also can use 1 big light emitting diode of power output, but power output is when becoming big, and temperature also will rise, so radiator structure need be set.In addition, from the angle in service life, also be that to be dispersed into a plurality of light emitting diodes more favourable.
Transparent resin general operable have PET, PBT, PEN, PC etc., the performance that these materials see through visible light is very excellent, but ultraviolet ray almost can't see through.If what light emitting diode sent is ultraviolet ray, then can not make waterproof cover 23 with these materials.Use in light emitting diode under the situation of ultraviolet light, operable have glass materials such as above-mentioned MMA resin and PFA, quartz glass, boron Gui acid glass, soda-lime glass.But glass lacks the shaping free degree, and damaged easily, thus among the embodiment of the present utility model 1 use be the MMA resin.
Adopt at light source under the situation of ultraviolet light source, also can use light supply apparatuses such as black light lamp, bactericidal lamp.But, because light irradiation device 5 will be set to the inside of washing machine body 1, so the light emitting diode that can make light source do very for a short time is the most suitable.In addition, light emitting diode 18 can be selected according to pointing to the purpose that angle (that is the emission angle of light, the luminosity on the normal optical axis is that 1 o'clock luminosity is reduced to 0.5 o'clock angle) is about 10 °～140 °.In addition, light emitting diode 18 can send the light that wavelength is 350nm～660nm, so can select polychromatic lights such as ultraviolet light, purple, green grass or young crops, monochromatic light such as green, yellow, red and white for use according to application target.
Light source is selected for use after the light emitting diode, can dwindle the volume of light source, thereby can be arranged on very compactly in the very little space.In addition, can also change irradiating angle (sensing angle) by changing light-emitting diode structure, the range of exposures in therefore can at random setting in the bucket 3.
Fig. 6 is the bacteria-eliminating efficacy performance plot in the washing machine of the utility model embodiment 1, wherein shows the wavelength (color) of light emitting diode 18 and the relation between the bacteria-eliminating efficacy.Test process is: at first make bacterial suspension in the water through sterilization, gather bacterium with test cloth, put in the washing machine with washings 14 then, wash; After washing is finished, carry out rinsing dehydration stroke, in the time that comprises the drying stroke, carry out illumination thereafter and penetrate with the water that is added with the light stimulus anti-biotic material.Bacterial population (the E of final residual on test cloth has been shown among Fig. 6
L) with the bacterial population (E of light pre-irradiation
O) ratio (logE
L/ E
O) and the light emitting diode wavelength between relation.Result from Fig. 6 as can be seen, though with wavelength the light (redness) of long 630nm also produce effect, the short more bacteria-eliminating efficacy of wavelength is high more, the light source of light irradiation device 5 uses ultraviolet ray the most suitable.
Therefore, light irradiation device 5 uses the light source that contains ultraviolet light most suitable, can be created on the hydroxyl free radical isoreactivity oxygen class free radical that can produce very big degermation under the photocatalysis expeditiously, improves bacteria-eliminating efficacy.
For this reason, be provided with in the washing machine of the utility model embodiment 1: the washtub 4 that is used to accommodate washings 14; Thereby make light stimulus anti-biotic material dissolve, add to make in the water light stimulus anti-biotic material to add water and be added to light stimulus anti-biotic material generator 10 in the washtub 4 with light stimulus effect; With carry out light-struck light irradiation device 5 to containing the washings 14 that the light stimulus anti-biotic material adds water.Like this, the illumination that light irradiation device 5 is launched is mapped to attached to the light stimulus anti-biotic material on the washings 14 and is added to light stimulus anti-biotic materials in the washtub 4 to be added when waterborne, will produce photocatalysis, generate the very big hydroxyl free radical isoreactivity oxygen class free radical of degermation, carry out degerming by its extremely strong acidization.Also degerming, antibacterial effect can have been given play to even light stimulus anti-biotic material and active oxygen free radical concentration are low.Because be the acidifying of active oxygen free radical to be decomposed utilize, antibiotic scope can enlarge, and also can play antibacterial effect for bacterium and mildew beyond coliform and the staphylococcus aureus.
In addition, be provided with electrolytic cell in the light stimulus anti-biotic material generator 10, be provided with the electrode 32 that contains metal at least in the electrolytic cell, in water, provide metal ion by electrolysis.Its result, owing to can make metallic element generation stripping with light stimulus effect by electrolysis, size and conduction time by the control electric current can be adjusted the metallic element concentration that the light stimulus anti-biotic material adds in the water, and therefore the metallic element of normal concentration can stably be provided.
In addition, by in the water that flows, dissolving the metallic element that to have the light stimulus effect with electrolytic cell 10, metallic element is added in the washtub 4, so just can control to the generation and the supply of light stimulus anti-biotic material interpolation water by simple apparatus structure.
In addition, in rinsing dehydration stroke, by being carried out illumination, penetrates the washings 14 that is impregnated with the light stimulus anti-biotic material interpolation water that is added in the washtub 4, the light stimulus anti-biotic material that is dissolved in the water is impregnated in the washings 14 effectively, and can generates the hydroxyl free radical isoreactivity oxygen class free radical that can produce very big degermation by photocatalysis.
In addition, when the light stimulus anti-biotic material interpolation water in washtub 4 is discharged from or after light stimulus anti-biotic material interpolation water is discharged from, penetrate by carrying out illumination by 5 pairs of washings of light irradiation device 14, just can carry out illumination and penetrate, generate the active oxygen free radical effectively the washings 14 that from light stimulus anti-biotic material interpolation water, exposes.
The effect of [table 1] silver ion+light
Above table 1 in the mildew that illustrated in the washing machine of the utility model embodiment 1 remove effect, its test process is as follows.Mildew is suspended in through in the water of sterilizing, takes the mildew bacterium with test cloth then, put in the washtub 4 with washings 14; Then, while carry out illumination after washing finished and penetrate and use light stimulus anti-biotic material (silver ion) to add water to carry out the situation of rinsing dehydration stroke and measure in the mildew clearance rate of the situation of not carrying out carrying out under light-struck condition rinsing dehydration stroke.As can be seen from Table 1, compare with not carrying out light-struck situation, the mildew clearance rate when carrying out illumination and penetrating is improved significantly, penetrates and can also play the effect of disposing mildew by silver ion being carried out illumination.
Table 2 concentration of silver ions and bacteria clearance
| Concentration of silver ions (ppm) | Laundry amounts (kg) | Clearance rate (%) |
| 0.01 | 0.5 | ＞99 |
| 0.03 | 3.5 | ＞99 |
| 0.10 | 7 | ＞99 |
Relation between the clearance rate of the concentration of light stimulus anti-biotic material (silver ion) and bacterium has been shown in the table 2.Concentration of silver ions changes according to the amount of washings 14, particularly, is under the situation of 0.5kg, 3.5kg and 7kg in the washings amount, and concentration of silver ions is set to 0.01ppm, 0.03ppm and 0.1ppm respectively.Test process is as follows: at first make bacterial suspension in the water through sterilization, gather bacterium with test cloth, will test cloth then and washings 14 is put in the washtub 4 together.After washing is finished, penetrate Yi Bian carry out illumination, carry out rinsing dehydration stroke Yi Bian add water with light stimulus anti-biotic material (silver ion).Then, the clearance rate of bacterium is measured.As can be seen from Table 2, even reach under the situation of 0.01ppm in that concentration of silver ions is low, penetrate also and can obtain very high bacteria clearance by carrying out illumination.
Fig. 7 A is the summary sectional view of the light illuminating method in the washing machine of expression the utility model embodiment 1, Fig. 7 B is the summary sectional view of the another kind of light illuminating method in this washing machine of expression, and Fig. 7 C is the summary sectional view of another light illuminating method in this washing machine of expression.As shown in Figure 7A, inner bottom part (the light stimulus anti-biotic material adds the part that stockpiles of water when the being rinsing) irradiation be arranged to towards interior bucket 3 of light irradiation device 5 is just passable.At this moment, can use and point to the smaller device in angle, penetrate carrying out illumination in the narrow range set, with the bacteria-eliminating efficacy that promotes that this is a part of.When carrying out rinsing, washings 14 constantly repeats along with the rotation of interior bucket 3 is mentioned the top, dropped to the light stimulus anti-biotic material again and add action in the water by baffle plate 11, so as long as face toward the words that the inner bottom part of interior bucket 3 shines, light can shine on the washings 14 certainly, thereby makes washings 14 obtain degerming.
Therefore, penetrate, can add water and be impregnated with washings 14 that the light stimulus anti-biotic material adds water the light stimulus anti-biotic material and carry out illumination reliably and penetrate by making light irradiation device 5 carry out illumination towards the inner bottom part of interior bucket 3.
In addition, carrying out illumination by the water surface that is added water by the light stimulus anti-biotic materials in the bucket 3 in 5 pairs of the light irradiation devices penetrates, for at the washings 14 that exposes washings 14 on the water surface and on the water surface, haunt, can under the state that is fully flooding light stimulus anti-biotic material interpolation water, carry out illumination and penetrate with very high efficient.
The interior bucket 3 that comprises the outer bucket 2 that is located in the body 1 in the washtub 4 and be arranged in the bucket 2 outside to rotate freely, bucket 3 rotations in motor 12 (drive unit) drives, internally the washings 14 in the bucket 3 stir.Then, carry out illumination and penetrate while change by the position that makes washings 14, can the washings 14 that coincide together be stirred, the washings 14 that exposes from the teeth outwards in the bucket 3 in making is replaced; So, can carry out illumination equably to washings 14 and penetrate, the active oxygen free radical that takes place on the light stimulus anti-biotic material can not occur irregular yet, thereby can improve bacteria-eliminating efficacy.In addition, alternately carry out positive and negative rotation, can improve the mixing effect of washings 14, carry out illumination equably and penetrate by bucket 3 in making.
In addition, under the situation of speed as 45 rev/mins speed rotation that washings can be mentioned earlier, fallen with baffle plate 11 by bucket in making 3 washings 14 being carried out illumination penetrates, can all effectively stir washings, and washings be carried out illumination equably penetrate.
In addition, light irradiation device 5 also can use the big device of the sort of irradiating angle as shown in Fig. 7 B.Though this situation can't resemble shown in Fig. 7 A illumination carried out in narrow scope concentrated area penetrated, can to shine uniformly in the bucket 3 in whole, degerming.In addition, because interior bucket 3 is made of stainless steel and other metal materials usually, when use pointing to the big light emitting diode 18 in angle, the inner surface of interior bucket 3 can reflect light, the direct light that light arrives light emitting diode 18 according to less than washings 14 on, realize that the chance of degerming also can increase.
But, under these circumstances, preferably be arranged to direct light and can be leaked to washtub 4 structure outward through cover 13, light can be used for effectively to carrying out degerming in the washtub 4 like this.Particularly when use has the light emitting diode 18 of ultraviolet wavelength,, can also suppress influence to human body by being arranged to the formation that direct light can not leak.Therefore, the angle initialization that is provided with that points to angle or light source by the light source with light irradiation device 5 becomes to make not directly inwardly bucket 3 external exposures of light, light can be directed in the interior bucket 3 with very high efficient, but also can reduce the influence of ultraviolet light to human body.

In addition, Fig. 9 is the summary sectional view of the light illuminating method in the washing machine of expression the utility model embodiment 2.As shown in Figure 9, on the diverse location of the circumference of the opening portion 2a of bucket 2, the irradiation area of light is cut apart outside a plurality of light emitting diodes 25,26 are set at, in each zone, can at random be set illuminating method.Therefore, if will and irradiation object between distance set shortly, just can be in each zone carry out illumination in the object set and penetrate shining.
In addition, after light emitting diode 18 is connected in parallel, can also be when rinsing and change illuminating method during dehydration.When rinsing, washings 14 constantly repeats earlier to be mentioned, to drop the light stimulus anti-biotic material by baffle plate 11 and add stirring operation in the water along with the rotation of interior bucket 3, if the bottom towards interior bucket 3 is shone, light is certain to shine on the washings 14, makes washings 14 obtain degerming.On the other hand, owing to will carry out the high speed rotation, washings 14 can become the state that is adjacent on the inwall of interior bucket 3 under action of centrifugal force during dehydration., shine by the bottom that makes bucket 3 in 25 pairs of the light emitting diodes in when dehydration, the top of bucket 3 is shone in 26 pairs of the light emitting diodes simultaneously, just can carry out illumination to washings 14 effectively and penetrate, the realization degerming for this reason.
In addition, the illuminating method of light emitting diode 25,26 also can be set according to the amount of washings 14.Though just mentioned the example that concentration of silver ions changes according to the amount of washings 14 among the utility model embodiment 1, the illuminating method of light also can change according to the amount of washings 14.Particularly, more after a little while, only allow the light emitting diode 25 of bottom of irradiation washtub 4 luminous in the amount of washings 14; And the amount of washings 14 more for a long time, and then light emitting diode 25 and 26 is all luminous, thereby can realize high efficiency degerming.
In addition, internally shine in bucket 3 interior same places, can make the part that is mapped to by illumination concentrated relatively, improve the formation efficiency of active oxygen free radical by using a plurality of light sources.And, by a plurality of light sources are set, can also reduce the load of each light source, prolong the life-span of light source.
In addition, on the diverse location by the circumference of the opening portion 2a side of bucket 2 outside a plurality of light sources are arranged on, just can carry out illumination to washings 14 and penetrate from different directions, illumination less than dash area can reduce, thereby can realize that illumination penetrate with very high efficient.
(embodiment 3)
Figure 10 is the sectional view of the light irradiation device of the washing machine among the utility model embodiment 3, and Figure 11 is the performance plot of the light irradiation device of the washing machine among the utility model embodiment 3.Because the basic comprising of light irradiation device is identical with the embodiment 1 and 2 of front, so only its difference is described here.
Normally used light emitting diode has maximum exposure intensity on optical axis, the angle that departs from optical axis is big more, and intensity is also just more little.But light emitting diode 27 is different, as shown in Figure 11, has exposure intensity angle little, that depart from optical axis on the optical axis (line that angle is 0 °) and becomes big intensity also with the tendency of grow.Therefore, this effect can smoothly realize by front end face depression or the leading portion face of light emitting diode 27 being made light emitting diode as shown in Figure 10.In a plurality of light emitting diodes 18, have at least one to be arranged to the big more exposure intensity of angle that departs from optical axis as described above also with regard to strong more light emitting diode 27, by these light emitting diodes are carried out parallel connection, just can at random set illuminating method.
Particularly, as described in example 2 above, when rinsing, make the light emitting diode 18 that has maximum intensity on the optical axis luminous, and the time not only make light emitting diode 18 luminous, also make simultaneously in that to depart from the light emitting diode 27 that has maximum intensity on the position of optical axis luminous in dehydration.In addition, illuminating method also can change according to the amount of washings 14.As, more after a little while, only make the light emitting diode 18 that has maximum intensity on the optical axis luminous in the amount of washings 14, and in the amount of washings 14 more for a long time, then not only make light emitting diode 18 luminous, also make simultaneously in that to depart from the light emitting diode 27 that has maximum intensity on the position of optical axis luminous.In this case, light emitting diode 18 and light emitting diode 27 promptly can be installed in the box body 20 as shown in Figure 10 like that, also can be arranged on like that as shown in Figure 9 on the diverse location of outer bucket 2 circumferences.
