- FIG. 20 shows a drive circuit 120 of the water treatment unit 100.
- Transformer 122 is connected to commercial power supply 121, and steps down 100V to a predetermined voltage. After the output voltage of the transformer 122 is rectified by the full-wave rectifier circuit 123, the output voltage is made constant by the constant voltage circuit 124.
- a constant current circuit 125 is connected to the constant voltage circuit 124. The constant current circuit 125 operates so as to supply a constant current to the electrode driving circuit 150 described later irrespective of a change in the resistance value in the electrode driving circuit 150.
- a rectifier diode 126 is connected to the commercial power supply 121 in parallel with the transformer 122. After the output voltage of the rectifier diode 126 is smoothed by the capacitor 127, the output voltage is made constant by the constant voltage circuit 128 and supplied to the central control unit 130.
- the central control unit 130 starts and controls a triac 129 connected between one end of the primary coil of the transformer 122 and the commercial power supply 121.
- the electrode drive circuit 150 is configured by connecting NPN transistors Q1 to Q4, diodes Dl and D2, and resistors Rl_R7 as shown in the figure.
- Transistor Q1 and diode D1 form photocoupler 151
- transistor Q2 and diode D2 form photopower blur 152. That is, diodes Dl and D2 are photodiodes, and transistors Ql and Q2 are phototransistors.
- the central control unit 130 also has a high level voltage on line L1 and a low level voltage on line L2 (or When a zero voltage (ie, “OFF”) is applied, diode D2 turns on, and concomitantly transistor Q2 turns on.
- a zero voltage ie, “OFF”
- diode D2 turns on
- concomitantly transistor Q2 turns on.
- the transistor Q2 is turned on, current flows through the resistors R3, R4, and R7, a bias is applied to the base of the transistor Q3, and the transistor Q3 is turned on.
- the central control unit 130 switches the control so that the current flows through the 114 in the reverse direction. In this case, transistors Ql and Q4 are turned on, and transistors Q2 and Q3 are turned off.
- the central control unit 130 has a power counter function, and performs the above-described switching every time a predetermined count is reached.
- the constant current circuit 125 outputs the output. Increase the voltage to prevent the current from decreasing. However, if the cumulative usage time is prolonged, the water treatment unit 100 reaches the end of its life, and the current cannot be prevented from decreasing even if the mode is switched to the forced electrode cleaning mode or the output voltage of the constant current circuit 125 is increased.
- the current flowing between the electrodes 113 and 114 of the 7 processing unit 100 is monitored by the voltage generated at the resistor R7, and when the current reaches a predetermined minimum current value, this is detected by the current detection circuit 160. Is trying to detect. Information that the minimum current value has been detected is transmitted from the photodiode D3 constituting the photo power plug 163 to the central control unit 130 via the phototransistor Q5.
- the central control unit 130 drives the warning notifying means 131 via the line L3 to cause a predetermined warning display to be displayed.
- the warning notification means 131 is arranged on the operation / display unit 81.
- the current is reduced to a predetermined maximum.
- a current detection circuit 161 for detecting that the current value has become greater than or equal to the current value is provided. Based on the output of the current detection circuit 161, the central control unit 130 drives the warning notification unit 131. Further, when the output voltage of the constant current circuit 125 becomes equal to or less than a predetermined minimum value, the voltage detection circuit 162 detects this, and similarly, the central control unit 130 drives the warning notification means 131.
- the drive circuit 120 drives the water treatment unit 100 mounted on the washing machine 1 as follows.
- FIG. 21 is a flowchart showing a sequence of inputting metal ions.
- the sequence in FIG. 21 occurs in the final rinsing step in step S405 (main water flow) in the flow in FIG. That is, when the final rinsing is started, it is checked in step S411 whether or not the input of metal ions has been selected. If “input of metal ions” is selected by the selection operation of the operation / display unit 81, the process proceeds to step S412. If not, the process proceeds to step S414.
- step S412 the main water supply valve 50a is opened, and a predetermined flow rate of water flows into the water treatment 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 current flowing between the electrodes is DC.
- the metal ion-containing water is supplied to the washing tub 30 from the water supply port 53.
- step S413 the rinsing water is stirred to promote the contact between the laundry and the metal ions. Stir for a predetermined time.
- step S414 it is confirmed whether or not the supply of the finishing agent is selected. If you have this confirmation step, put it in front of you. In step S411, the confirmation may be made at the same time as the confirmation of the metal ion dosing setting. If “injection of finishing agent” is selected by the selection operation through the operation Z display section 81, the process proceeds to step S415. If not, the process proceeds to step S406. In 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 the finishing agent is put in the finishing agent room 55, the finishing agent is put into the washing tub 30 together with the water from the siphon part 57. Since the siphon effect occurs only when the water level in the finishing agent chamber 55 reaches a predetermined height, the liquid finishing agent is supplied to the finishing agent room 55 until the time comes and water is injected into the finishing agent room 55. Can be kept.
- sub water supply valve 50b closes. Note that this water injection step, that is, the finishing agent charging operation is automatically executed if the finishing agent charging step which is related to whether the finishing agent is put in the finishing agent chamber 55 is selected.
- step S416 the rinsing water is stirred to promote the contact between the laundry and the finish. After stirring for a predetermined time, the process proceeds to step S405.
- the finishing agent is charged into the rinsing water after a predetermined time has elapsed. Therefore, if the metal ion and the finishing agent (softening agent) are simultaneously added to the rinsing water, the metal ions react with the softening agent component and the antibacterial properties are reduced, but the metal ions have sufficiently adhered to the laundry. Since the finishing agent is added later, the reaction between the metal ions and the finishing agent components is prevented, and the antibacterial effect of the metal ions can be left on the laundry.
- the metal forming 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 sterilizing effect, and copper ions eluted from the copper electrode have an excellent antifungal effect.
- the alloying power of silver and copper can elute silver ions and copper ions simultaneously.
- Silver ions are cations.
- the laundry is negatively charged in water, so silver ions are electrically adsorbed to the laundry.
- Silver ions are electrically neutralized when adsorbed on the laundry. For this reason, it reacts with the salt ion (anion), which is a component of the finishing agent (softener).
- anion which is a component of the finishing agent (softener).
- silver ions are absorbed into the laundry over time, so some time must be allowed before the finishing agent is charged. 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 introduced into the washing tub 30 from the main water supply pipe 52a through the detergent room 54.
- the finishing agent is introduced into the washing tub 30 from the finishing agent room 55. In this way, metal ions are rinsed into water Since the path for charging and the path for charging the finishing agent into the rinsing water are separate systems, metal ions pass through the path for charging the finishing agent to the rinsing water and remain in this path. When the metal ions come into contact with the finishing agent to form a compound and lose their antibacterial activity, they cannot be treated.
- 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, the metal ion concentration in the washing tub 30 can be controlled by controlling the amount of water flowing into the water treatment unit 100 and the ion elution time. It is easier to obtain the metal ion concentration.
- the voltage required to maintain a constant current increases. If the voltage exceeds a predetermined threshold value, it is determined that the wear of the electrodes 113 and 114 has reached the limit, and the warning notification means 131 is notified of that fact. In addition, a message prompting replacement of the water treatment unit 100 is issued. In response, the user replaces the water treatment unit 100.
- washing machine 1 in which the water treatment unit 100 is combined in addition to the fully automatic washing machine as in this embodiment, a horizontal drum (tumbler type), an oblique drum, a dryer that also serves as a dryer, or a two-layer type is used. This applies to all types of washing machines.
- the posture of the water treatment unit is the “horizontal posture” in the above embodiment
- the “vertical posture” that is, the posture in which the longitudinal direction of the case is vertical and the inflow port and the outflow port project horizontally.
- it can be used in a "sideways posture”, that is, a posture in which the longitudinal direction of the case is horizontal and the inlet and outlet protrude horizontally.
- the content of the water treatment is not limited to elution of metal ions, and it is also possible to implement generation of electrolyzed water.
- Industrial applicability INDUSTRIAL APPLICABILITY The present invention can be used not only for washing machines, but also for general appliances using water, such as dishwashers and humidifiers.
