Operation If “input of metal ions” is selected in the selection operation through the Z display section 81, the flow proceeds to step S412. If it is not selected, the process proceeds to step S414.
- step S412 the main water supply valve 50a is opened, and a predetermined flow rate of water flows through the ion elution unit 100.
- the drive circuit 120 applies a voltage between the electrodes 113 and 114 to elute ions of the metal constituting the electrodes into water.
- the metal ion-containing water is supplied from the water supply port 53 to the washing tub 30.
- step S413 the rinsing water is stirred to promote the contact between the laundry and the metal ions. Stir for a predetermined time.
- the pulsator 33 After adding the metal ion-containing water, the pulsator 33 is used to stir the rinsing water and laundry for a certain period of time (assuming it to be stirred with a certain degree of intensity as in a normal rinsing), then stand still, or You may switch to gentle agitation.
- the metal ions By initially stirring the rinse water and the laundry into which the metal ion-containing water has been introduced, the metal ions can be spread to all corners of the laundry, and thereafter, can be kept still or gentle for a certain period of time. By stirring, metal ions can be adhered well to the laundry.
- the metal ions are thoroughly stirred to spread the metal ions throughout the laundry, and then the mixture is stopped or gently stirred, thereby reducing the load on the motor 41 that performs the stirring operation. Power consumption can also be reduced.
- the laundry may be immersed in rinsing water containing metal ion-containing water for a longer time, for example, about 30 minutes to 1 hour.
- rinsing water containing metal ion-containing water for a longer time, for example, about 30 minutes to 1 hour.
- Laundry clothes and linens used in hospitals. Clothes and linens used outside hospitals. Even when clothes and linens are used outside hospitals, stool adheres and is contaminated with E. coli. It can remove bacteria and kill bacteria on moldy laundry (such as unit bus curtains).
- bacteria may grow, such as water that has not been sterilized with hypochlorous acid, such as tap water, for example, rainwater, pumping water, or bath water that has been left alone. Even when water is used for washing, the water itself is disinfected and killed, so it can be used for washing with ease.
- hypochlorous acid such as tap water, for example, rainwater, pumping water, or bath water that has been left alone. Even when water is used for washing, the water itself is disinfected and killed, so it can be used for washing with ease.
- step S414 it is confirmed whether or not the supply of the finishing agent is selected.
- This confirmation step may be preceded, if at all.
- step S411 the confirmation may be made simultaneously with the confirmation of the metal ion injection setting. If “injection of finishing agent” has been selected in the selection operation through the operation display section 81, the flow advances to step S415. Selection If not, the process proceeds to step S406.
- step S406 the pulsator 33 is turned upside down to loosen the laundry, and the laundry is distributed in the washing tub 30 in a well-balanced manner to prepare for the spin-drying operation.
- step S415 the sub water supply valve 50b is opened, and water flows into the finishing agent chamber 55 of the water supply port 53. If a finishing agent is put in the finishing agent room 55, the finishing agent is put into the washing tub 30 together with water from the siphon section 57. Since the siphon effect occurs only when the water level in the finishing agent chamber 5 reaches the predetermined height, the liquid finishing agent is supplied with the finishing agent until the time comes and water is injected into the finishing agent room 5 5. It can be kept at 5.
- the sub water supply valve 50b When a predetermined amount of water (a sufficient amount to cause the siphon section 57 to have a siphon action or more) is injected into the finishing agent chamber 55, the sub water supply valve 50b is closed.
- the water injection step that is, the finishing agent charging operation is automatically executed if the finishing agent charging step is selected, regardless of whether the finishing agent is put in the finishing agent chamber 55.
- step S416 the rinsing water is stirred to promote the contact between the laundry and the finishing agent. After stirring for a predetermined time, the process proceeds to step S406.
- the finishing agent is charged into the rinsing water after a predetermined time has elapsed. Therefore, if the metal ions and the finishing agent (softening agent) are added to the rinsing water at the same time, the metal ions react with the softening agent components to reduce the antibacterial properties, but after the metal ions have sufficiently adhered to the laundry, the finishing is completed. The reaction between the metal ions and the finishing component is prevented, and the antibacterial effect of the metal ions can be left on the laundry.
- the metal constituting the electrodes 113 and 114 is preferably silver, copper, or an alloy of silver and copper.
- Silver ions eluted from the silver electrode have an excellent bactericidal effect, and copper ions eluted from the copper electrode have an excellent protective effect.
- Silver ions and copper ions can be eluted simultaneously from an alloy of silver and copper.
- Silver ions are cations. Laundry is negatively charged in water, which causes silver ions to be electrically absorbed by the laundry. Silver ions are electrically neutralized when they are absorbed by the laundry. Therefore, chloride, which is a component of the finishing agent (softener), It is difficult to react with anions. However, silver ions are adsorbed on the laundry over time, so it is necessary to allow some time before the finish is added. Therefore, 10 minutes of stirring time is required after silver ion injection. A stirring time of about 3 minutes after the finish is charged is sufficient.
- Metal ions are supplied from the main water supply pipe 52 a through the detergent chamber 54 to the washing tub 30.
- the finishing agent is put into the washing tub 30 from the finishing agent room 55.
- the path for charging the finishing agent to the rinsing water is a metal ion.
- metal ions do not come into contact with the finishing agent remaining in this pathway to become a compound, and the antibacterial activity is not lost.
- the stirring of the rinsing water is performed with the introduction of the metal ions and the finishing agent.
- the metal ions and the finishing agent can be securely adhered to the entire laundry.
- the input of the metal ions is an optional matter, and when the input of the metal ions is not selected, the input of the finishing agent is performed in an initial stage of the final rinsing step. Therefore, the time required for the final rinsing step can be limited to the time required for attaching the finish to the laundry. In addition, the finish can be securely attached to the entire laundry by stirring the rinse water.
- the charging operation itself is performed when the finishing agent is charged. For this reason, the operation of selecting the addition of the finishing agent does not necessarily have to be performed. If the finishing agent is not desired to be introduced, it is sufficient if the finishing agent is not simply put into the finishing agent chamber 55.
- the sequence of FIG. 11 is obtained by deleting step S 4 11 1 (selection of metal ion input) from the sequence of FIG.
- the input of the finishing agent can be arbitrarily selected, but the metal ions are always input.
- the sequence of Fig. 12 is the sequence of Fig. 10 with the following modifications. is there. That is, step S 4 21 (water level adjustment) was placed before step S 4 12 (input of metal ion-containing water). Step S 4 2 2 (water level adjustment) was also placed before step S 4 15 (finish agent charging operation). This is for the following reason.
- Metal ions are introduced in a form contained in water. Finishing agent is also charged with water. This inevitably causes the water level in the washing tub 30 to rise. If the water level in the washing tub 30 is high, there is a possibility that the washing tub 30 will overflow when metal ions or finishing agents are charged. It is wasteful to wash away metal ions and finishing agents due to flooding. Also, the noise during flooding may be annoying.
- step S421 the drain valve 68 is opened prior to the introduction of metal ions, and a little water is discarded.
- the amount to be discarded is the same as or less than the input amount of the metal ion-containing water, and an amount that does not cause the washing tub 30 to overflow.
- step S422 the drain valve 68 is opened and the water is slightly discarded before the finish agent is charged. The amount to be discarded should be the same as or less than the amount of water containing the finishing agent, and should not cause overflow of the washing tub 30.
- Fig. 13 is the sequence of Fig. 12 with the following modifications. That is, first place step S 4 1 4 (selection confirmation of finishing agent input), and if finishing agent selection is selected, proceed to step S 4 11 1 (selection confirmation of metal ion input), if not, select It was decided to proceed to step S406 (balance).
- step S 4 11 If the selection of “input metal ions” is confirmed in step S 4 11 1, step S 4 2 1 (water level adjustment) is followed by step S 4 1 2 (input of metal ion-containing water) ⁇ step S 4 1 3 ( Stirring) ⁇ Step S 4 2 2 (water level adjustment) ⁇ Step S 4 15 (finishing agent charging operation) ⁇ Step S 4 16 (stirring). If the selection of “Metal ion injection” is not confirmed in Step S 411, Step S 4 2 2 (Water level adjustment) is followed by Step S 4 15 (Finishing agent charging operation) ⁇ Step S 4 16 ( (Mixing).
