- An object of the present invention is to provide a washing machine in which metal ions having antibacterial properties can be added to water in a predetermined step of the washing process, and in which the effect of adding metal ions can be fully exhibited. Aim.
- a washing machine that performs a balance correction process in consideration of the presence of the input metal ions should be provided. With the goal.
- a washing machine is configured as follows.
- the time of the predetermined step when metal ions are put into the washing machine is as follows. It is longer than when no metal ions are injected. In the first place, it takes a certain amount of time for the metal ions to be sufficiently adsorbed on the laundry, but according to this configuration, when the metal ions are supplied, the process is more complicated than when the metal ions are not supplied. Since the time is longer, metal ions can be sufficiently adhered to the laundry and the desired antibacterial effect can be exhibited.
- the washing machine is configured as follows. That is, in a washing machine in which metal ions having antibacterial properties can be introduced into water at a predetermined step in the washing process, the strong water flow period and the weak water flow period or the strong water flow period and the stationary period are added to the predetermined process. Shall be placed. In the first place, it is not always necessary to stir the water vigorously to attach metal ions to the laundry. According to this configuration, the metal ions are uniformly dispersed in the water, and the strong water flow period for the metal ions to reach every corner of the laundry, and also the metal ions adhere to the laundry. Since there is a period of quiet water flow or a period of stillness waiting quietly, there is no need to accelerate the damage to laundry and increase power consumption. Also, due to weak water flow, The person knows that the washing machine is running and does not have to worry that the washing machine has failed.
- the time ratio between the strong water flow period and the weak water flow period or the strong water flow period and the stationary period is constant regardless of the amount of water in the washing tub and / or the amount of laundry. And According to this configuration, control programming is facilitated.
- the time ratio between the strong water flow period and the weak water flow period or the strong water flow period and the stationary period is changed according to the amount of water in the washing tub and / or the amount of laundry. It was made to be.
- the ratio of the strong water flow period and the weak water flow period or the ratio of the strong water flow period and the stationary period can be appropriately set according to the amount of water and the amount of laundry, thereby reducing damage to the cloth and unnecessary consumption of electric power. can do.
- the washing machine is configured as follows.
- antibacterial metal ions can be added to the water that is poured when rinsing.
- the required amount of metal ions can be attached to the laundry without the metal ion concentration in the water being reduced even when the water is rinsed.
- the washing machine is configured as follows. That is, in a washing machine in which antibacterial metal ions can be injected into water at a predetermined stage during the washing process, when an imbalance is detected during the spinning of the washing tub, which is performed after the injection of the metal ions. It is assumed that processing different from that when unbalance is detected when metal ions are not input is performed. According to this configuration, when the imbalance is detected during the spin-drying after the metal ions are input, the balance correction process can be executed in consideration of the antibacterial effect of the metal ions.
- the different treatment is a balance correction rinsing in which metal ion added water is supplied and agitated. According to this configuration, even when the balance is rinsed by newly pouring water, the effect of the antibacterial treatment applied to the laundry is not diminished because the water contains metal ions. Further, in the present invention, in the washing machine configured as described above, when the balance correction rinsing is performed by supplying the metal ion added water, the metal ion input amount is made smaller than the metal ion input amount in the previous process. According to this configuration, the consumption of metal ions can be suppressed without unnecessarily replenishing the laundry once treated with metal ions with a large amount of metal ions.
- the different treatment is to supply and / or notify that the supplied water is the non-metal ion-added water while supplying the non-metal ion-added water. It was determined that the balance was adjusted and rinsed. If metal ion-added water is used to correct the balance in the first place, the metal may be consumed earlier than the design life, and the time when metal ions cannot be used may come earlier. According to this configuration, when the balance is rinsed with non-metal ion-added water in order to suppress the consumption of metal ions, the effect is displayed, Z or notified, and the user cannot obtain the desired antibacterial effect. You know what is possible.
- the different processes are a stop of the spin-drying operation, a display indicating that unbalance has been detected, and a Z or notification.
- the balance correction rinsing, etc. it is not necessary to carry out the balance correction rinsing, etc., but to inform the user that imbalance has occurred and have the user correct the balance of the laundry with his / her hand, thereby reducing the consumption of metal ions. It is possible to obtain the antibacterial effect expected by the user while suppressing the noise.
- the process to be executed is changed depending on the number of times. If the balance was corrected with metal ion-added water every time an imbalance was detected in the first place, the metal that would be the source of metal ions would be quickly consumed. According to this configuration, it is possible to suppress the consumption of metal by mixing the processing of the balance correction without using the metal ion-added water.
- the washing machine configured as described above, a plurality of types of processing after the unbalance detection are prepared, and the type and / or order of the processing to be executed can be selected. .
- metal ions are spared. Depending on the user's wishes, it is possible to give priority to maintaining antimicrobial effect by using it without priorities or to save metal ions.
- the metal ions are generated by an ion eluting unit that applies a voltage between the electrodes to elute the metal ions. According to this configuration, the concentration of metal ions in the water can be easily adjusted by controlling the voltage / current and controlling the voltage application time, and the desired antibacterial effect can be produced on the laundry.

- a predetermined amount of metal ion-added water is poured into the washing tub 30, and after that, metal ion-free water is poured to the set water level. Voltage application to 1 14 stops.
- the main water supply valve 50a continues to supply water even after the ion elution unit 100 stops generating metal ions, and stops supplying water when the water level inside the washing tub 30 reaches the set water level.
- the metal ions and the finishing agent (softening agent) are simultaneously added in step S422, but this is not always necessary when the ion elution unit 100 is generating metal ions during the siphon action. This does not mean that the time for the finish (softener) to be added to the washing tub 30 must completely overlap. Either one may be shifted back and forth. After the ion elution unit 100 stops generating metal ions, the finishing agent (softening agent) may be added when the metal ion-free water is additionally injected. In short, it suffices that the input of metal ions and the input of finishing agent (softening agent) are performed in one sequence.
- terminal 115 is connected to electrode 113
- terminal 116 is connected to electrode 114, and so on.
- Each is integrally formed of the same metal material. Therefore, unlike the case where different metal parts are joined together, there is no potential difference between the electrode and the terminal, and no corrosion occurs. Further, the integration makes it possible to simplify the manufacturing process.
- the interval between the electrodes 113 and 114 is set to be tapered so as to become narrower from the upstream side to the downstream side. Therefore, when the electrode is worn down and the plate thickness becomes thinner along with the flow of water, the electrode is less likely to cause chattering and is not easily chipped. Also, there is no risk of excessive deformation and short circuit.
- Electrodes 1 13 and 1 14 are supported in such a way as to create a space between them and the inner surface of case 110. Therefore, a metal layer does not grow from the electrodes 113 and 114 to the inner surface of the case 110, and a short circuit does not occur with the other electrode.
- the portions of the terminals 115 and 116 located inside the case 110 are protected by sleeps 174 and 175 made of an insulating material, so that there is little wear due to conduction. This prevents the terminals 115 and 116 from being broken during use.
- the locations where the terminals 115 and 116 are provided are locations that enter inside from the upstream end.
- the electrodes 1 13 and 1 14 wear down from the part where the distance between them becomes smaller.
- the terminals 1 15 and 1 16 are the upstream part of the electrodes 113 and 114, but they are not at all ends, but the parts that entered inside from there. Since it is formed at the end, it is not necessary to worry that the depletion starting from the end of the electrode reaches the terminal and the terminal is broken from the base.
- the upstream side of the electrodes 113, 114 is supported by the first sleep 174 and the support part 176.
- the downstream sides of the electrodes 113, 114 are supported by supporting portions 177, 178.
- the electrodes 113, 114 do not vibrate even in the water flow because they are firmly supported on the upstream side and the downstream side. Therefore, the electrodes 113 and 114 do not break due to vibration.
- Terminals 1 1 5 and 1 1 6 project downward through the bottom wall of the case body 1 10a You. For this reason, steam may come into contact with the case 110a (when washing with bath water, steam easily penetrates into the washing machine 1), or the case 110 may be cooled by passing water. Therefore, even if dew condensation occurs on the outer surface of case 110, the condensed water will flow down the cables connected to terminals 115, 116 and terminals 115, 116 and case 115 Does not stay at the boundary with 0. Therefore, a situation where the terminals 115 and 116 are short-circuited by dew condensation water does not occur. Since the case body 110a is arranged with the long side horizontal, the terminals 115, 116 provided on the sides of the electrodes 113, 114 are connected to the bottom of the case body 110a. It is easy to adopt a configuration that projects downward from the wall.
- the outlet 1 1 2 of the ion elution unit 100 has a smaller cross-sectional area than the inlet 1 1 1 and the flow resistance is larger. For this reason, the water that has entered the case 110 from the inlet 1 11 overflows without creating an air pocket inside the case 110, and soaks the electrodes 113, 114 . Therefore, there is a portion in the electrodes 113 and 114 that is not involved in the generation of metal ions, and a situation in which this portion remains undissolved does not occur.
- the cross-sectional area of the outlet 1 1 2 is smaller than the cross-sectional area of the inlet 1 11, but also the cross-sectional area of the internal space of the case 110 gradually decreases from the upstream side to the downstream side. For this reason, turbulence and bubbles are unlikely to be generated inside the case 110, and the water flow is smooth. Bubbles do not dissolve in the electrodes. The metal ions also quickly leave the electrodes 113 and 114 and do not return to the electrodes 113 and 114, so that the ion extraction efficiency is improved.
- the ion elution unit 100 is arranged in the main water supply passage 52a having a large flow rate, and the amount of flowing water is large. For this reason, the metal ions are immediately carried out of the case 110 and do not return to the electrodes 113 and 114. Therefore, the ion elution efficiency is improved.
- the outlet 1 1 2 is provided at the lowest position in the internal space of the case 110.Therefore, when the flow of water to the ion eluting unit 100 is stopped, the water in the ion eluting unit 100 All flow out of outlets 1 1 2. Therefore, the residual water in case 110 freezes during cold weather, and ion elution unit 100 breaks down, or Little happens when you destroy it.
- a strainer 180 exists upstream of the electrodes 113 and 114. Therefore, even if solid foreign matter exists in the water supplied to the ion elution unit 100, the foreign matter is captured by the strainer 180 and does not reach the electrodes 113, 114. Therefore, the foreign matter does not damage the electrodes 113, 114, and the electrodes are not short-circuited by the foreign matter, so that an excessive current does not flow or insufficient generation of metal ions occurs.
- a strainer 118 exists downstream of the electrodes 113 and 114. Even if the electrodes 113, 114 are worn out or become brittle due to long-term use, they may be broken and the debris may flow out, but the debris will be captured by the strainer 181, It does not flow further downstream. Therefore, the fragments of the electrodes 113 and 114 do not damage the articles on the downstream side.
- foreign substances and electrode fragments may adhere to the laundry without the strainers 180 and 181. obtain. Foreign matter or electrode fragments may stain or damage the laundry, and if dehydration and drying are performed with foreign matter or electrode fragments attached to the laundry, the person who later wears the laundry If you touch them, they may feel uncomfortable or, in extreme cases, get injured, which may lead to a situation, but the strainers 180, 181 can avoid such situations.
- step S4243 the rinse water into which the metal ions and the finishing agent (softening agent) have been introduced is stirred by a strong water flow (strong water flow) to bring the laundry into contact with the metal ions and the finishing agent (softening agent) for the laundry. Agent) is promoted.
- step S424 the agitation is performed with a weak water flow (weak water flow). The aim is to make metal ions adhere to the surface of the laundry and exert its effect. If the water flow is weak, the user does not misunderstand that the operation of the washing machine 1 has been completed.
- the display can be displayed on the operation Z display section 81 to call the user's attention, stop stirring and drain water. It may be left stationary.
- the stirring is performed with a strong water flow (strong water flow).
- strong water flow strong water flow
- step S405 the process moves to step S406.
- step S406 the pulsator 33 is flipped in small increments to loosen the laundry. This allows the laundry to be distributed in the washing tub 30 in a well-balanced manner, and prepares for the spin-drying operation.
- FIG. 15 is a sequence diagram showing the operation of each component from step S422 to step S406.
- Step S 4 2 3 strong water flow
- step S 4 24 weak water flow
- step S 4 25 strong water flow

- the weak flow period may be replaced by a stationary flow period.
- step S425 strong water flow
- step S425 strong water flow
- step S406 balance
- the motor 41 When the water flow is generated, the motor 41 periodically repeats ON (forward rotation), OFF, ON (reverse rotation), and OFF.
- the ratio between the ON time and the OFF time depends on the amount of water and the amount of Z or the amount of washing.

- Step S 4 2 3 strong water flow: 1.9 / 0.7
- Step S 4 2 4 weak water flow: 0.6 Z 10.0
- Step S 4 25 strong water flow: 1.4 Z 1.0
- Step S406 (balance): 0.9 Z0.4
- the total time of the step is longer than when metal ions are not added.
- This program was used because it takes a certain amount of time for the metal ions to be sufficiently absorbed by the laundry. As a result, the metal ions can be sufficiently attached to the laundry, and the desired antibacterial effect can be exerted.
- step S 4 23 strong water flow
- step S 4 24 weak water flow
- step S 423 strong water flow
- step S 424 weak water flow
- the ratio of the strong water flow period to the weak water flow period can be appropriately set according to the amount of water and the amount of laundry, and it is possible to reduce damage to the cloth and not to consume unnecessary power.
- metal ions and finishing agent be originally charged separately. This is because metal ions are converted into compounds when they come into contact with the softener component, and the antibacterial effect of metal ions is diminished. However, considerable amounts of metal ions remain in the rinse water. The effect reduction can be compensated to some extent by setting the metal ion concentration. Therefore, metal ions and a finishing agent (softener) are added at the same time, and although the effect of imparting antibacterial properties is slightly reduced, the rinsing time is shortened compared to the case of separately adding and rinsing each, and the This is to improve efficiency.
- the metal ions are injected into the washing tub 30 from the main water supply path 52 a through the detergent room 54.
- the finishing agent (softening agent) is supplied from the finishing agent room 55 to the washing tub 30.
- the route for introducing metal ions into the rinsing water and the finishing agent Since the entry route is different from the system, the metal ion does not come into contact with the finishing agent (softening agent) until it meets in the washing tub 30, and the metal ion has a high concentration of the finishing agent (softening agent). )
- the explanation has been made assuming that the rinsing water is stored in the washing tub 30 and the rinsing is performed, but the final rinsing is performed with the ⁇ rinsing rinse ''. May go. In that case, the water to be poured shall be ice with added metal ions.
- the input of the metal ion as the first finishing substance and the input of the finishing agent (softening agent) as the second finishing substance are both optional items. Either one can be stopped or both can be stopped. If both inputs are stopped, the process proceeds from step S420 to step S401, as described above. Hereafter, the case where only one of the two types of finishing materials is introduced will be described.
- step S421 If it is determined in step S421 that the finishing materials to be charged are not two types, that is, metal ions and softeners, it means that only one of the two is selected. In this case, the process proceeds to step S 4 26.
- step S426 it is confirmed whether the finishing material to be charged is metal ions. If it is a metal ion, the process proceeds to step S 427. Otherwise, go to step S428.
- step S427 the main water supply valve 50a is opened, and water flows through the main water supply path 52a.
- the sub water valve 50b does not open.
- the drive circuit 120 applies a voltage between the electrodes 113 and 114 to elute ions of the metal constituting the electrode into the water.
- a predetermined amount of metal ion-added water is poured into the washing tub 30, and after that, metal ion-free water is poured to the set water level, and then the rinse water metal is added.
- the application of the voltage to the electrodes 113 and 114 is stopped.
- the main water supply valve 50a continues to supply water even after the ion elution unit 100 no longer generates metal ions, and stops supplying water when the water level inside the washing tub 30 reaches the set water level.
- step S4 23 strong water flow
- step S 4 24 weak water flow
- step S 4 25 strong water flow
- step S406 balance
- step S426 If it is determined in step S426 that the finishing substance to be charged is not a metal ion, the finishing agent (softening agent) is charged alone. In this case, the process proceeds to step S428.
- step S4208 both the main water supply valve 50a and the sub water supply valve 50b are opened, and water flows to both the main water supply path 52a and the sub water supply path 52b.
- the ion elution unit 100 is not driven, and no metal ions are generated.
- the finishing agent softener
- the main water supply valve 50a continues to supply water even after the sub water supply valve 50b is closed, and stops supplying water when the water level inside the washing tub 30 reaches the set water level.
- step S428, go to step S432. Thereafter, as in the case where the metal ions and the finishing agent (softening agent) are simultaneously injected, step S 4 23 (strong water flow) ⁇ step S 4 24 (weak water flow) ⁇ step S 4 25 (strong water flow) ⁇ Proceed to step S406 (balance).
- the weak flow period can be replaced by a stationary flow period.
- step S4208 only steps S424 (strong water flow) and S406 (balance) are placed, and step S424 (strong water flow) can be completed in a short time, for example, two minutes. It is possible.
- step S406 the washing machine 1 vibrates greatly in the subsequent water removal process. Vibration due to laundry imbalance is detected by physical detection means such as a touch sensor, shock sensor, acceleration sensor, or by software detection means such as analyzing the voltage / current pattern of the motor 41. Is done.
- Figure 16 is a sequence diagram showing the operation of each component in the “balance rinsing”. After water supply, agitation and agitation are performed in agitation 1 to change the arrangement of the laundry. After that, stir agitation in Stirring 2 to balance the laundry in preparation for resuming the spinning cycle. Time distribution is, for example, 2 minutes and 5 seconds for water supply, 1 minute for agitation 1 and 30 seconds for agitation 2.
- the motor 41 periodically returns ON (forward rotation), OFF, ON (reverse rotation), and OFF.
- the ratio between ON time and OFF time depends on the amount of water and the amount of Z or laundry.
- the time ratio (ON / OFFF) at the rated load is as follows (unit is seconds).
- the first “different treatment” is to “supply water with added metal ions and perform balance correction too”. In this way, even when new water is poured and the balance is rinsed, the metal ions are added to the water, and the water is applied to the laundry. The effect of the antibacterial treatment does not diminish.
- the metal ion input amount may be smaller than the metal ion input amount in the previous process. In this way, the consumption of metal ions can be suppressed without unnecessarily capturing a large amount of metal ions in the laundry once treated with metal ions.
- the second ⁇ different treatment '' is ⁇ balance correction rinsing by supplying and stirring metal ion-free water while indicating and / or notifying that water is being supplied. is there.
- metal ion-added water is used at the time of balance correction, the metal of electrodes 113 and 114 will be consumed earlier than the design life, and the time when metal ions cannot be used may come earlier.
- the balance is rinsed with non-metal ion added water in order to suppress the consumption of metal ions, the effect is displayed on the operation / display unit 81 or is notified by voice, etc. By this means, the user can be informed that the desired antibacterial effect may not be obtained.
- the third “different treatment” is “stopping spin-drying and displaying and notifying or notifying that imbalance has been detected”.
- the user is notified that imbalance has occurred, and has the user correct the balance of the laundry with the user's hand, without performing a balance correction rinse or the like.
- the antibacterial effect expected by the user can be obtained while suppressing the consumption of water.
- the metal which is the source of the metal ions, ie, the electrodes 113, 114, was quickly depleted. According to the above, it is possible to suppress the wear of the electrodes 113 and 114 by mixing the processing of the balance correction without using the metal ion added water.
- a plurality of options of "processing after unbalance detection" are prepared, and the type and / or order of the processing to be executed can be selected. Can be.
- the constant current circuit 125 of the drive circuit 120 controls the voltage so that the current flowing between the electrodes 113 and 114 becomes constant. This makes the amount of metal ion eluted per unit time constant. If the amount of metal ions eluted per unit time is constant, it is possible to control the metal ion concentration in the washing tub 30 by controlling the amount of water flowing into the ion elution unit 100 and the ion elution time. Therefore, it becomes easy to obtain a desired metal ion concentration.
- the current flowing between the electrodes 113 and 114 is DC. If this is an exchange, the following phenomenon occurs. That is, when the metal ion is, for example, silver ion, the silver ion once eluted returns to the electrode by the reverse reaction of Ag + + e- ⁇ Ag when the polarity of the electrode is reversed. Such is not the case with direct current. Scale is deposited on the side of the electrodes 113 and 114 used as the cathode. If DC continues to flow without reversing the polarity and the amount of deposited scale increases, it becomes difficult for the current to flow, and it becomes difficult to elute metal ions at a predetermined rate. In addition, the problem of "one-sided reduction" in which the electrode used as an anode wears out quickly also occurs. Therefore, the polarities of the electrodes 113 and 114 are periodically inverted.
- the electrodes 113 and 114 gradually deplete as the metal ions continue to elute, and the elution amount of the metal ions decreases. If used for a long time, the elution amount of metal ions becomes unstable or the specified elution amount cannot be secured. For this reason, the ion elution cut 100 is made replaceable, and when the life of the electrodes 113 and 114 comes, a new unit can be replaced. Further, the operation of the electrodes 113, 114 is reached. The user is notified through the Z display section 81 to encourage maintenance such as replacement of the ion elution unit 100. .
- the present invention can be applied to all types of washing machines such as a horizontal drum (one tumbler type), a diagonal drum, a dryer and a double-layer type. Applicable to Industrial applicability
- the present invention can be used for imparting the antibacterial action of metal ions to textiles using a washing machine regardless of whether it is for home use or business use.
