But, the water in this moment in the bucket 4 is that described water storage barrel 31 is included hypochlorous water through dilution, in the hypochlorous acid concentration that obtains under the state of dilution more than 0.5 above-mentioned (ppm), should adjust the concentration in the described water storage barrel 31 in advance.

Like this, in the 1st rinse cycle, can obtain hypochlorous bactericidal action.

Even the 1st rinse cycle also will be opened draining valve 16 at last, the water in making in the bucket 4 is discharged by drainpipe 17.

Then, in the 2nd rinse cycle, with the above-mentioned the same water-supply valve 42 of opening, running water will inwardly be supplied with in the bucket 4 by the main path 30a that gives water route 30, until the required water level of the above-mentioned decision of arrival.

Then, again with above-mentioned the same, under the static state of interior bucket 4, make stirring body 7 revolutions by driving mechanism 10, the water in making in the bucket 4 stir with washings and wash.The washing of this moment is also not contain hypochlorous water and carry out rinsing with neither containing washing agent, thus, can be when detergent ingredients residual on the washings be removed in dilution, the dilution removing is soaked in the hypochlorous acid in the washings.

Last at the 2nd rinse cycle also will be opened draining valve 16, and the water in making in the bucket 4 are discharged by drainpipe 17.

In the dehydration of back, make interior bucket 4 and stirring body 7 one high speed rotaries by driving mechanism 10, rely on its centrifugal force that the moisture that contains in the washings is separated from dewatering hole 5, and discharge by drainpipe 17.

If it is and different with above-mentioned steps, in the initial operational phase, select sterilizing function " nothing " back to start running, then the 1st rinse cycle is also the same with the 2nd rinse cycle, use and neither to contain washing agent and also do not contain hypochlorous water and wash (rinsing), " having " of this sterilizing function, the selection of " nothing " can be not yet according to user's wish, but automatically perform by the setting of washing machine, also can take the step different to carry out with above-mentioned process.

As mentioned above, this structure is to be provided with by contact the back with water at interior bucket 4 slowly to discharge hypochlorous solid 37, inwardly supply with the hypochlorous water that contains from 37 releases of this solid in the bucket 4 again, bacterial reproduction in the hypochlorous bactericidal action that dependence is supplied with suppresses in bucket 4 and the washings, so can suppress the mouldy, smelly of these objects and jaundice, and can suppress that the human body generation is infected etc.Add, hypochlorous acid also has discoloration, can make the washings bleaching thus.

Again, this structure is that giving in the water route 30 of feedwater is provided with secondary path 30b and main path 30a in inside bucket 4, the former is provided with the portion that is provided with 39 that above-mentioned solid 37 can be set, and the latter then is not provided with portion 39, wherein at least with feeding water by selecting execution in the inside bucket 4 in the path that is provided with the portion of setting 39.Thus, can obtain the inwardly bucket 4 interior hypochlorous bactericidal actions of supplying with selectively according to user's wish and program.

And, this structure is the inside that the portion that is provided with 39 that will above-mentioned solid 27 be set is located at water storage barrel 31, solid 37 discharges hypochlorous acid to the water that is accumulated in these water storage barrel 31 inside, hypochlorous these water storage barrel 31 interior water that will contain release are more inwardly supplied with in the bucket 4, thus, can after the solution that generates sufficient hypochlorous acid concentration, inwardly supply with in the bucket 4.

And for example preceding described, in laundry processes, by retaining in water storage barrel 31, generate the solution of sufficient hypochlorous acid concentration, solution after generating is inwardly supplied with in the bucket 4 in the 1st rinse cycle thereafter, just can generate the solution of hypochlorous acid concentration in a short period of time efficiently, obtain sufficient bactericidal effect.And,, when beyond laundry processes, not generating the solution of hypochlorous acid concentration,,, prolong the service life of solid 37 so can suppress from solid 37, to discharge hypochlorous acid because of not retaining in the water storage barrel 31 in this occasion.

The laundering process of this structure through use the water that contains washing agent carry out washings washing (laundry processes) stage, use and contain hypochlorous water and carry out the stage of washings washing (the 1st rinse cycle), use and do not contain the stage that washing agent and hypochlorous water carry out washings washing (the 2nd rinse cycle) then.In the laundry processes therein, from the isolated organic matter that is immersed in the interior bucket 4 interior water of washings hypochlorous acid can't be played one's part to the full, so will avoid hypochlorous too much supply, and in not containing organic the 1st rinse cycle thereafter, use contains hypochlorous water and carries out the washings washing, can obtain hypochlorous bactericidal action effectively thus.In this occasion,,, further prolonged the service life of solid 37 so only need a small amount of hypochlorous acid because of efficiently having brought into play hypochlorous effect.

In the 2nd rinse cycle, do not contain washing agent and hypochlorous water carries out the washings washing by using, residual hypochlorous acid in bucket 4 and the washings in both can having removed avoids the distinctive stink of hypochlorous acid to remain in interior bucket 4 and the washings, can prevent that again washings from fading.

In addition, especially in this structure, solid 37 is shaped in the water miscible polymer body by medicines such as chlorination fulminuric acid compound are dispersed in, and after this water miscible polymer body dissolves contained medicine is entered in the water, just can need bring into play bactericidal action for a long time and not with safeguarding.Again, water miscible polymer body is adsorbed on the fiber and dirt particle of washings, has the effect that prevents the phase inter coagulation,, uses this solid 37 that is, can improve the dirt effect again that prevents of washings, improves detergency.

Adopt this structure, can utilize water filling portion 71 that solid is set, do not need to be provided with again in addition portion to water route 30.

In this occasion, water level H height when setting the portion that is provided with 78 of solid 62 to such an extent that throw in softeners than the siphonic outlet 81 of softener storage part 75, thus, viscosity is big, the easy film forming softener in surface can be attached to the surface of solid 62, so can avoid the medicine deterioration of solid 62.

In this occasion, can not supply with from the hypochlorous feedwater that contains that solid 62 discharges by softener storage part 75 yet, but independent the supply.Again, solid 62 also can be arranged on the top (upstream) of water injection box 72.

In washing machine, also be provided with not shown water-supply valve sometimes, water for bathing inwardly can be supplied with in the bucket 4 by this water-supply valve.As previously mentioned, contain a large amount of bacteriums in this water for bathing, its quantity can reach 10 ⁴～10 ⁶Individual, in addition, also contain the organic matter of number (ppm)-10 numbers (ppm).Therefore, for these materials of oxidation can expend hypochlorous acid, bactericidal action can not be brought into play fully effectively.

Strengthen the hypochlorous acid quantity delivered in inside barrel 4 when for this reason, preferably in inside bucket 4, supplying with water for bathing.Its method is to strengthen the water yield that contacts with solid 62, perhaps increases contact time.When in inside bucket 4, supplying with water for bathing, can automatically carry out said method.

When in inside bucket 4, supplying with water for bathing,, also can detect the dirt of washings, adjust automatically to increase and decrease by dirt sensor 18 though do not limit hypochlorous quantity delivered.

In the washing after hypochlorous acid is supplied with the neutralization supply, also cover plate 25 can be locked in blocking, contact with hypochlorous acid to prevent the user.Again, also can detect, only when this cover plate 25 is in blocking, supply with hypochlorous acid by locking to cover plate 25.

In addition, as washing methods, also can be through carry out with the water that contains washing agent washings washing (laundry processes) on one side stage, then by for example make interior 4 low speed revolution in this in bucket 4 feedwater so that do not contain that the washings that dewaters after the water saturates washings of washing agent washs the stage of (being so-called trickle rinsing or expelling water and rinsing), use contains hypochlorous water and carries out the stage that washings washs (rinsing) then.

Adopt this method, not only can obtain hypochlorous bactericidal action, and, wash with dewatering with the water saturates that does not contain washing agent, so can economize the consumption of about water because of in interior bucket 4 and in the outer bucket 2, not accumulating washings before this.

Have, hypochlorous generation can be different because of the temperature contrast of supplying with water again.For example, near summer of 20 ° or when supplying with water and being hot water or not yet cooling water for bathing, hypochlorous stripping quantity just increases in water temperature, and performance surpasses the bactericidal action that needs, otherwise when if water temperatures such as winter are low, hypochlorous stripping quantity just reduces.

Thus, preferably use cooling-water temperature sensor 47 to detect the temperature of washings, control the water yield that contact with solid 37,62 and contact time etc., just can under any water temperature condition, produce an amount of hypochlorous acid, the bactericidal action that acquisition is appropriate according to the result who detects.That is, when water temperature is higher, the water yield that minimizing contacts with solid 37,62 and contact time etc., otherwise, when water temperature is low, the water yield that increase contacts with solid 37,62 and contact time etc.But the final hypochlorous acid amount that produces does not reduce to water temperature just the same when low when will temperature of washing water higher, and this is because the high more bacterium of temperature is just many more, so hypochlorous generation excessively can not be reduced.

Producing hypochlorous solid and can make shape beyond aforesaid lever and the ring-type by contacting with water, also can be powder.

Be placed on solids 62 in the box body 56 and also can be arranged on the portion that is provided with 39 in the water storage barrel 31 again.

In addition, the present invention is not limited to above-mentioned and illustrated embodiment, can suitably change enforcement in the scope that does not break away from main design.

The present invention has following effect.

Adopt the washing machine of technical scheme 1, under the hypochlorous acid bactericidal action of in wash bucket, supplying with, can suppress the bacterial reproduction in wash bucket and the washings, so can suppress mouldy, smelly, turn to be yellow and produce infection etc.

Adopt the washing machine of technical scheme 2, can be according to user's wish and program, by the hypochlorous bactericidal action of selecting to obtain in wash bucket, to supply with.

Adopt the washing machine of technical scheme 3, can after the solution that generates sufficient hypochlorous acid concentration, in wash bucket, supply with.

Adopt the washing machine of technical scheme 4, the hypochlorous solid of release is disposed easily, be convenient to dress and get.

Adopt the washing machine of technical scheme 5, can utilize water filling portion to be provided with and discharge hypochlorous solid with water filling road.

Adopt the washing machine of technical scheme 6, can more can carry out sterilization to water for bathing with imitating.

Adopt the laundering process of technical scheme 7, not only can obtain hypochlorous bactericidal action effectively, and its distinctive stink can not remained in wash bucket and the washings, can prevent that also washings from fading.

Adopt the laundering process of technical scheme 8, not only can obtain hypochlorous bactericidal action effectively, but and the consumption of conserve water.
